The high level of morbidity and mortality indicates the current crisis, the need for in-depth study and adoption of urgent measures to improve the health of the population [61]. Particularly alarming in the trend among children, whose bodies are in the stage of growth and on interaction even with minimal adverse environmental factors react by pathological development.[68, 6, 7] The increased sickness rate of children in Russia (on the basis of clinical examination in 2002) was recorded for all categories of diseases according to the report “On the health status of children in Russia during the period from 1992 to 2002”. [7, 51] According to the government statistics, the sickness rate of child population is increasing annually by 4-5 %. At the present time no more that 10 % of children of senior preschool age and no more than 5 % of children of older adolescents can be considered completely healthy. Almost 60% of children have chronic diseases. In separate industrialized regions of Russia up to 40 % of pathological changes of health are due to harmful effects of air pollution and water pollution, soil, poor quality of food, production environment, level of medical care and life conditions. Significant contribution of environment factors to the development of various types of pathology of children makes it necessary to develop a system of medical and ecologically rehabilitation of children living in ecologically disadvantaged areas. To form high risk groups among children’s population to carry out adequate medical and preventive measures it is necessary to take into account the relationship between the health status of children and factors of environment, which to some extent are indicators of risk. In this regard, it seems topical the introduction of noninvasive methods of screening of diseases, allowing to draw significant numbers of children and develop a system of approaches to their recovery. In 1998 at the initiative of a number of environmental experts (Federal Environmental Fund of Russia, Association of environmental funds of the RF), doctors (Children’s Republican Clinical Hospital, Research Institute of Transplantation and Artificial Organs), sociologists (Center for the Protection of Children and Adolescents “Preodolenie”). There was established Ecorehabilitaion Health Сentre “Green House”. Its primary objective is the realization of the principle of human medical skilled care of every child or teenager. With it all it was proposed that a special attention would be given to children living in disadvantaged, in terms of ecology, regions. Modern methods of diagnostics, qualification of clinicians of various specialities allowed to work out the original technologies of diagnostics treatment, prevention and rehabilitation of children living in adverse environments. The study was carried our within the framework of the All-Russia Public Movement “Children – the future of Russian”. Funding of the program “Sanatorium rehabilitation of children from areas of ecological trouble, suffering from chronic diseases for 2000-2002”, was provided at the expense of the Federal Environmental Fund of Russia, the regional public organization “Hematologists of the world to children”. Environmental Safety Policy provides for a comprehensive solution of the three key tasks: prevention and reduction of environmental pollution, protection and restoration of natural complexes, rehabilitation of the health of the population living in ecologically unfavourable territories. Significant improvement of ecological situation in the coming years doesn’t seem possible, so in this situation the only effective way to oppose anthropogenic environmental factors is medical-ecological 5 rehabilitation, allowing to minimize the risk and harm to human health in large industrial cities. Recommendations of the State Duma to the RF Government and to the subjects of the Federation in letter № 3.13-684 of 26.08.98 indicate the necessity to implement rehabilitation programs. Statistics show and increasing number of diseases of the musculoskeletal and endocrine systems, mental and nervous disorders, chronic respiratory diseases, infectious and parasitic diseases, disorders of the immune status, malignant tumors of children. Taking into consideration that environmental factors contribute significantly to the development of pathological processes of children, there is a need for early preclinical diagnostics and development of a system of medical - ecological rehabilitation of children living in ecologically unfavorable areas. The purpose of the study: the scientific justification of the use of rational methods of screening and medical-ecological rehabilitation of children living in ecologically unfavourable areas (for example, settlements in Sverdlovsk and Tula regions). Objectives: 1. Analysis of the sanitary conditions of the selected areas. 2. Screening and in-depth survey of children in the selected locations to form high-risk groups with ecologically dependent violations of health. 3. Evaluation of information of non-invasive autonomic-resonance electro-diagnostic test (VRT), used as a method of prenosological diagnostics to form risk groups among child’s population. 4. Development of a different approach to the choice of the principles bringing into a healthy state of child’s population of ecologically unfavourable areas. Scientific novelty of the study. It was been development and tested in practice an integrated approach, based on screening tests of the child’s population living in ecologically unfavourable areas, to indentify children having a high risk of ecologically dependent diseases in order to carry out a set of preventive and curative measures in accordance with a risk group. Practical significance and implementation of the research results. The obtained results are recommended for use in practical work of health authorities to rehabilitate children from areas of ecological trouble, evaluation of sanitary-hygienic state of the environment and social conditions of environment where children live on the basis of the high prevalence of certain diseases, as well as for assistance to health service in conducting consultations and survey of children in their regions. A survey of children with the help of non-invasive method of bio-resonance diagnostics (VRT) allows to screen at the optimal time and thus significantly reduce, the time and cost to indentify prenosological and chronic diseases of children. The results of the studies are used to develop “Medico-ecological rehabilitation of the population sub program” under the program “Environmental Protection in Tula region in 2001-2005”. The devised method of organizing and conducting health measures is implemented in several other regions (Arkhangelsk, Moscow, Yaroslavl regions, Primorsky Kray, the Republic of Karelia, and Khakassia) with the participation of the State Enterprise “International Children’s Center”, which is one of the participants in the federal target program “Development of All-Russia children’s centres “Eaglet” and “Ocean””. In 2001-2005 2,638 children were sent to get some rest and health-environmental 6 rehabilitation to rest homes and sanatoriums. The methodical educational materials for children and parents were issued. Regulations issued for the protection. Population peculiarities in ecologically unfavourable areas form the specific structure of infant morbidity and determine the severity of pathology. A rational approach to screening to identify child’s pathology in view of ecological trouble areas allows to determine risk groups and to develop an adequate strategy for bringing into a healthy state and preventing ecological diseases of children. It is advisable to use non-invasive method of bio-resonance diagnostics (VRT) to determine the extent of toxic load on the body while examining large numbers of children in ecologically unfavourable areas.

REVIEW OF THE LITERATURE. HEALTH STATUS OF CHILDREN AS A CRITERION OF SOCIOHYGIENIC WELFARE OF THE POPULATION. 1.1. Socio-economic factors and their impact on children’s health. 1.2. Ecology and sickness rate of children (factors and the development of specific pathological conditions). 1.3. Approaches to preventions and rehabilitation of ecologically-dependent diseases of children. 1.1 Socio-economic factors and their impact of on children’s health. Studies of factors affecting health, showed that about 50% account for socio-environmental conditions and lifestyles, 18-25% - biological and genetic, 10-20% - climatic and environmental influences, 10-15 % - health organization (68,72], i.e. social and environmental factors are leading among other reasons that affect health. It is known that economic growth indexes cannot be the only indicators of society development. At present, the formation of a social state became a state philosophy of European countries with a social market economy. In Russia the transition to a market economy extremely strained social problems and led to an abrupt decline in population living standard which focuses the results of the state in social policy. According to Goscomstat of Russia, in 2000 in Russia 30,2% (nearly one third of the population), had cash incomes below the subsistence level. The standard of living, i.e. the extend of the vital interests of the people and their preferences, is one of the most important integral characteristics of the socio-economic system. At 29th UN Statistical Commission Session in February 1997 was approved the minimum national social data set recommended by the Working Group on International Statistical Programs and Coordination of the UN Economic and Social Council, half of them (7 out of 14) are health and hygienic indicators [27]. Children’s health is the most important integral indicator of their well-being in specific social conditions and reflects an integrated system of material and spiritual relationships that exist in a society. Every aspect of public policy is reflected in one way or another on the medical characteristics of the children’s population. In the period of a social and economic crisis first of all suffer the least socially protected sections of a society which include children as well. In the early 90-s children of Russia were the first to take the blow of “shock therapy”. Splash of morbidity and mortality of children signaled the public about the viciousness of the new adopted guidelines of the socio-economic transformations. In 1993 the infant mortality rate rose sharply to 19,9 per 1000 births (in 1990 – 17,4 per 1000). In the Russian Federation 1990-1998 are characterized by a steady deterioration of the health status of children and teenagers. Of the total number of children born in 1998 only 20% can be considered healthy, 44% are at risk and 35% were born sick [12]. Children at the age of 0-14 years old had frequency of hyperthyroidism 3,8 times as many, diseases of the musculoskeletal system and connective tissue 2,2 times as many, anemia 2,2 times as many, diseases of the circulatory system 2,1 times as many, allergic diseases by 71,4%, neoplasms by 74,1%. Maximum growth rates of the diseases’ number are found among teenagers. The frequency of anemia has increased 3,8 times more, diseases of the endocrine system – 2,8 times, diseases of the musculoskeletal system – 2,6 times, diseases of the digestive system-1,9 times, allergic diseases – 1,6 times, diseases of the circulatory system – 1,9 times. The number of children with functional disabilities and chronic diseases significantly increased. Reactive states and psychopathies, as a response to the negative impact of environmental factors, have grown in children by a third. 8 “Trofologichesky syndrome” – disharmonic physical development, reduction of functional reserves, delay of sexual development becomes typical for teenagers [6,7]. In subsequent years (1999-2003) the situation with children’s sickness rate has not only improved but continued to deteriorate: there was marked increase in sickness rates for all major classes of diseases [76]. Statistics of morbidity of population, including children are generally based on visits of doctors. Clinical examination results most fully characterize a picture of health status of the population. Clinical examination allows to identify not only chronic and acute diseases with clinical manifestations but also early, preclinical forms proceeding without violating of organs and systems function. [19, 51, 99]. It should be noted that a five-year period of 1991-1995 had the lowest socio-economic indicators for the period of 1966-2000 [76]. At that time Russia’s government was forced to admit that during conducting economic reforms accompanied by declining living standards of the population consequences of their impact on children’s conditions were not taken into account, compensatory and protective measures were not held in necessary volume. Among the most significant social (non-medical) conditions and factors impacting negatively on activities of medical services of children’s health protection determining the main trends in dynamics of indicators of their health status are lack of funding of health and medical science, the adverse socioeconomic conditions of the majority of the population, continuing environmental degradation in many regions. As mentioned above, children’s health can serve as an indicator of social welfare, and the State’s attitude to children determines the degree of its civility. The instability of the social economic situation of recent years has noticeably worsened the situation of children, possibilities of a family, the state concerning their livelihoods and development. This has resulted in deterioration of the main indicators that determine the health of the child population. A vivid illustration of the role of social factors in forming health, physical development and functional status of children are the results of the study carried out by the Institute of Social Hygiene Economics and Management of Health, N.A. Semashko RAMS. Survey of parents of 1100 children (Muscovites of 4years old attending kindergartens) clearly demonstrated in influence of a social status of families on a child’s health – the distribution of ratings indicates a worse situation of health among those children who are brought up in the economically less advantaged families. Social differences affect the prevalence of harmful habits in a family, recreation and sport activities: the proportion of children travelling to resorts with their parents, as well as involved in sport activities twice as big among wealthier families. Socio-economic status of a family affects not only a level of physical development of a child, but also his progress at school, an opportunity to visit additional classes (music, foreign languages), i.e. the process of comprehensive development of a child [32, 98, 48]. 1.2. Ecology and sickness rate of children (factors and the development of specific pathological conditions). Adverse social and economic factors, increased sharply in recent years, mental stresses and demands to the mechanisms of stress-stability not only adults but also children and teenagers significantly affect their mental health. For example, territorial analysis of areas of Volgograd has shown that visiting doctors by children in connection with mental disorders is higher in regions with low per head income of the working population [66, 97]. Mental health of children begins to develop in the prenatal period. Exposure of mother to heavy metals, polycyclic aromatic hydrocarbons leads to a violation of a reproductive function, complicated childbirth, 9 may cause neurotoxic effect on a fetus. The consequence of this may be a subsequent decline of cognitive functions of a child and his intellectual development [65, 90, 121]. Child’s body is more sensitive to the action of harmful factors including carcinogenic. Moreover their impact can begin as early as a prenatal period of development of an organism, when a mechanism of the so-called transplacental carciongenesis is switched on. It should be also indicated that children’s malignant tumors are among medical and geographical health criteria of population used in assessing an ecological status of a territory. Areas with excess child’s cancer incidence rate in 1,5-2 times are referred to zones of extreme ecological situation in 2 or more times – the zones of ecological disaster. As additional indicators of an ecological condition of a territory the data of the violation of women’s reproductive function (a complication of the course and outcome of pregnancy), are used a frequency of low birth weight (less than 2500 g), etc. [37], as the state of the reproductive function is the most important biological and social indicator of women’s health. Her condition is affected by many factors, including factors of production and environment, socio-economic indicators of life and etc. [87, 83, 122, 127]. As epidemiological data show there is a strong connection between a violation of women’s reproductive function and cancer risk of posterity. Thus, according to a large national study it was found a trustworthy connection between children’s cancer risk and pathology of the pregnancy. Parents’ work under the influence of harmful factors also significantly increased the risk of cancer with children. In this connection it should be noted that a profession is often a marker of social status of a man [85, 86]. Speaking about the role of various factors in forming children’s health we must not forget that Russia is divided into climatic, administrative and economic regions, sharply different in accordance with levels of development. Natural and climatic conditions have a tremendous impact on living standards in Russia, because the territory is crossed by several climatic zones. In adverse climatic and environmental conditions of emergency a child has an additional stress of functional systems which contributes to the formation of hidden and then apparent deviations in health status and imbalance to physiological standards of central Russia [15, 93]. These data revealing the fundamental biosocial regularities of formation of health directly indentify the need and urgency of solving social problems related to livelihood of children, including these items in the strategic documents on development of the country and close monitoring of their practical realization at all levels [49]. This is especially important that the negative effect of harmful environmental factors on a child’s body appears more actively on an unfavourable social background [91, 92, 31]. Children’s health is one of the most sensitive indicators of the change in environmental quality. As the level of pollution is increasing the number of children in the population with ecological changes of health is increasing too. [114, 115]. The reaction of a child’s organism to an impact of unfavourable environmental factors is sufficiently non-specific and is characterized by reduction of immunologic reactivity and deterioration of general health indicators. Moreover sensitivity of children to suck an effect is particularly enhanced during critical periods of their growth and development. It is the highest with the embryo, newborn and a child of an early age [102, 128, 133]. WHO studied a part of environmentally caused diseases among children of the European Regions [96]. The results convincingly showed that about one-third of all children and teenager’s morbidity (0-19 years old) can be attributed to unsafe and unhealthy environmental conditions [127, 131, 134, 130, 132]. The United States face similar problem. The USA in the 20th century infant mortality from asthma 10 doubled, significantly increased the child’s leukemia and brain tumors. Encephalopathies got a wide spreading. [124, 135]. Due to the urgency of the problem, WHO had established a special subdivision dealing with the problem of “environment – children’s health”. In 2003 this problem was declared the main theme of World Health Day. Currently the major studies to assess the impact of pollution on children’s health are focused on solving of the following tasks: Assessment of air pollution and air quality of homes as a risk factor for asthma and other allergic diseases of children; Revelation and evaluation of chemical and physical risk factors development of leukemia and brain cancer of children; Revelation and evaluation of an impact of chemical risk factors including SOP, lead and mercury on the neuropsychiatric status of the child; Revelation and evaluation of an impact of chemical risk factors on an endocrine status and a reproductive system of a child. As a rule, children more than adults, spend time outdoors. Because of the physiological needs of a child’s organism, children are basically more physically active which is accompanied by an increase in pulmonary ventilation [117]. Air pollution by various toxicants even at low concentrations leads to an increase of level of their effects on a child’s organism [104, 105, 111, 129]. Under the influence of xenobiotics children suffer various clinical manifestations which are determined by a class of substance dangerous a duration of exposure as well as age and individual sensitivity (106, 107, 110, 112). Clinical spectrum of environmentally determined syndromes and diseases is extremely wide, and their detection and differential diagnosis are extremely challenging. Children living in areas of ecological trouble, together with general deterioration of health indicators showed increase in the frequency of allergic diseases (allergodermatozy, food allergy), the respiratory organs (acute pneumonia and bronchitis, bronchial asthma), congenital malformations, diseases of the nervous system, gastro intestinal tract, kidneys, and ENT-organs, there endocrinopathy, stunted physical and neuropsychological development (Table 1.2.1). According to leading experts involved in the study of the health status of children in regions of ecological trouble, all these manifestations characterize the environmental maladaptation syndrome [13, 100]. It is known that the physiological adaptation abilities of a child's organism to rapidly changing environmental conditions is lower than of adults’. Growing child's organism is most sensitive to external influences. This primarily refers to children of the first years of life, Table 1.2.1 Comparative analysis of the main forms of pathology of children (per 1000 people) in the areas of ecological trouble and on average in Russia * 11 Prevalence Pathology form On average in Russia In the areas of ecological trouble Allergic diseases 35 180 Food allergies at an early age 70 400 Asthma 10 24 Respiratory allergies 48 122 Recurrent bronchitis 6 94 Vegeto-vascular dystonia 12 144 Gastritis and gastroduodenitis 60 180 Nephropathy 33 187 Chronic diseases of the nose, sinuses 21 31 Chronic tonsillitis 116 239 Chronic otitis 7 9 Encephalopathy 30 50 * According to U.E. Veltischev’s data, 2000. quote from: [101]. when the most intensive development of the organism occurs. As the physical mass during the growth of a child increases his body accumulate various xenobiotics selectively depositing in certain tissues and organs. It’s connected with physiological characteristics of a child's organism: increased permeability of skin and blood-brain barrier, mucous membranes of the respiratory and digestive systems, the low acidity of gastric juice, immaturity of liver enzyme systems, low glomerular filtration rate of kidneys, immaturity of a system and general immunity [33, 116]. With increasing concentration of xenobiotics, intensity or time of exposure of physical and biological factors and their combinations with each other, adaptive systems of a body begin to work with greater congestion, there is a failure of strain compensation and a state of exhaustion or depletion of separate systems take place. This condition is called "anthropo-ecological exhaustion" and is characterized by failure of adaptation mechanisms to transition to a disease [13]. It creates a basis for greater sickness rate of child’s population and a growth of environmentally caused diseases. Prolonged exposure of low concentrations of xenobiotics on the body of a child has a genotoxic, metabolic and carcinogenic effects, fermentopathic membranopatological action [14, 5]. A major feature of a child’s organism is existence of critical periods of growth and development when sensitivity of a child's body to external pathogenic factors (xenobiotics, physical factors) is increasing. As a result of increasing body weight of a child nonmetabolized xenobiotics are constantly accumulated in his body (polychlorinated compounds, 12 dioxins, heavy metals, etc.) selectively depositing in certain tissues and organs. The embryo, newborn and a child of an early age have the highest sensitivity to chemical agents. Placenta has a sufficiently high permeability for these substances, which creates conditions for their accumulation in fetal tissues [44]. Birth defects and development anomalies can be the result of it [74, 36, 79, 80]. There is a direct link between air pollution (suspended solids, sulfur dioxide, carbon monoxide, nitrogen dioxide) and the frequency of stillbirths in industrial cities [23]. Investigation of the role of metals in the genesis of various diseases of children shows that some metals are uniformly distributed in various organs (chromium, manganese, cobalt, nickel, arsenic, selenium). Other metals (cadmium, mercury) cumulate; in renal tissue [30, 58, 63, 70, 108, 119, 109]. The kidneys are the main organ egesting endogenous and exogenous toxins. It has been found a high risk (absolute, relative, attributive) of forming of nephropathy and abnormalities of urinary organs of children living in a region polluted with heavy metals salts [62]. Accumulation of lead and cadmium in biological media of a child's body with immune imbalance contribute to a chronic disease of a gastrointestinal tract, kidney and urinary tract infections of children [81, 57, 59, 95, 126]. The immune system is one of the major homeostatic systems of a body and largely determines a degree of human health and its adaptive capabilities [24]. Child's immune system can be regarded as a sensitive indicator reflecting environment pollution [67, 50.113]. This primarily refers to a body of children of the first years of life, when the most intensive development is carried out. In the process of a child’s growth and increase of physical weight, many xenobiotics are accumulated in his body, and they are selectively deposited in certain tissues and organs. Critical periods of development of the immune system are established, when the impact of xenobiotics leads to a change or distortion of immune reactions that leads to allergies, or to the oppression of the immune reactions, ie formation of secondary immune deficiencies [1, 2, 45]. In numerous studies conducted in different regions of the country, the relationship between the level of environmental contamination by anthropogenic chemicals and morbidity of children in traced [125, 4, 11, 47, 46]. In large industrial cities with high levels of air pollution the frequency of abnormalities in the physical and neuro-psychological development of children, allergic diseases, the manifestations of secondary immunodeficiency, chronic inflammatory or degenerative diseases, cancer is increased [77, 8, 94, 18, 56, 43, 31]. In the centers of metallurgy disease incidence of children with chronic diseases of the respiratory, digestive and central nervous system, skin, eyes, including allergic diseases is 40% higher than in the relatively "clean" areas and cities [69, 17, 123]. 13 Ecologically unfavourable areas are characterized by a high frequency of endocrinopathy, most often it comes to thyroid disease [75]. Chronic somatic diseases, the presence of chronic foci of infection in otolaryngology and urinary tract infections, manifestations of secondary immunodeficiency or allergy are found with 40% of children [84]. It is shown that in zones of ecological tension and crisis, where there are elevated levels of atmospheric pollution by hydrogen sulfide, hydrocarbons, ammonia, sulfur-fluoride gas, there is a backlog of children in physical, neuro-psychological development, there is a high prevalence of chronic disease 3-4 times larger than disease incidence of children of "clean" regions [22, 118]. Diagnosis of environmentally dependent diseases of children consists in comparing of data on environmental contamination by xenobiotics with indicators of hypersensitivity of a child's body. It should be taken into account the age reactivity and possible hereditary predisposition of a child to an illness. The complexity of ecological and hygienic diagnosis of disease of children is that this may not be specifically expressed morbidity associated with the change in the reactivity of a child's body. On the other hand, it may be non-specific manifestations of a specific origin, due to the influence of factors that have tropism to different organs and systems. And finally, it can be diseases caused by indirect effects of exogenous factors that have become pathogenic under the influence of the environment [42]. Establishment of cause-effect link between an illness of the child and an action of a certain chemical agent is an important and challenging task. A child who is suspected of environmentally dependent disease is to be carefully clinically examined with skin test, functional and load tests, a full clinical analysis of blood, urine and in accordance with testimony - determination of xenobiotics and their concentrations in biological fluids and substrates (blood, urine, hair, precipitated teeth removed polyps and tonsils). It has become topical the use of new technologies to identify the causes of health deterioration by examining the results of socio-hygienic and ecological monitoring of the factors stipulating for the reduction of public health, as well as the mathematical prediction of the risk of disease in the childish population [34, 35, 47]. To confirm the causal role of xenobiotics in a disease of a child modern techniques of molecular biochemistry, genetics and immunology are used. Now such methods are available only to clinical institutions, general hospitals and children's ecopathologi centres [28, 29, 75, 38]. 1.3 Approaches to prevention and rehabilitation of ecologically dependent diseases of children. From the above there is a need for targeted state and regional programs of prevention and rehabilitation of children with ecologically dependent pathology as the right of a child to health protection. The legal basis for the creation of these programs are the following regulatory documents of international and state level: The UN Convention on the Rights of the Child (1990); World Declaration on 14 the Survival, Protection and Development of Children (2000); Constitution of Russia (1993) ; Basic Laws of Russia on Health Care № 5487-1 (1993), the Law "On Basic Guarantees of the Rights of a Child in Russia", the Law "On Sanitary and Epidemiological Welfare of Russia; RF Government Resolution of 29 December 2001 № 916 "About the all-Russia system of monitoring of the state of physical health, physical development of children, teenagers and youth”; Concept of demographic development of the RF for the period up to 2015 (Government Decree of 24.09.2001. № 1270-p); RF Government Resolution dated June 1, 2000 № 426 "On Approval of the sanitary-hygienic monitoring" (as amended on April 29, 2002). It should be emphasized that the above mentioned documents are only a small part of the legal framework upon which is based the scientific, medical and organizational activities aimed at improving the health status of children. A presidential program "Children of Russia" has been working sinece 1993. In 2003, the subprogram “A Healthy Child" is included in it and is financed. It says in particular: "The impact of environmental and socio-psychological factors, the intensity of which in the past decade has increased immensely, leads to the fact that children’s health is assessed as catastrophic. In the subjects of the RF the proportion of healthy children is from 4 to 10 percent. One of the reasons for the progressive deterioration of children’s health, especially infants and teenagers, is the inefficiency of ongoing preventive and rehabilitative measures aimed at preserving and strengthening physical and mental health of children and teenagers, adaptation to changes in social, economic, ecological, educational environment". The problem of progression deterioration of children’s health is multifaceted. According to the above data, the imperfection of the legislative regulation of children's health protection, the negative effects of socio-economic changes in the country, the ambiguity of organizational changes in the field of health care, etc. have been focused in it. So far as the problem is interdisciplinary in nature, for its comprehensive solution it is necessary to attract structures of different profile and the level from federal, regional to non-governmental organizations and funds, which aim to protect public health. The decisive condition is to be a systematic approach in which each block of the system is interconnected with its other components, has clearly defined objectives and methods of their solution. An important system unit is the existence of well-organized and structured dynamic information base which tasks include the following [34, 35]: • monitoring of environmental pollution both according to individual pollutants of classes I and II toxicity and according to their total effects (in the case of single direction of pathogenic action); • choice of diseases that can serve as markers of ecological trouble in the region; • periodic refinement of the relationship between morbidity and the nature and level of chemical pollution of the environment; 15 • creation of integrated medico-ecological databases according to "marker" nosological groups of different territorial-administrative levels (from regional to federal); • medico-ecological ranking of territories in accordance with various degrees of threat to health; • dynamic risk assessment and forecast of changes in health status of children in accordance with a changing environmental situation; • assessment of effectiveness of natureprotective measures. This system is to operate within the SHM, as directly corresponds to its tasks, and it is to lean on existing automatic state information systems (ASIS) “Health – Environment”. In addition it provides the basis for the following units, namely: the territorial arrangement of priorities in solving environmental problems and the formation of groups of high risk of development of ecologically dependent diseases of children. Together with forming these blocks the first priority is to define the criteria and ranking problems [53]. Thus, a formation of high-risk groups taking into account the existing harmful factors, and pathological conditions caused by them proposes a development of criteria which depend on the specificity of a harmful factor (content in environmental objects, route of entry, etc.), the nature of pathology caused by it, child population groups which are most affected by its influence, etc. As a result, it defines the principles of clinical examination, rehabilitation and prevention of ecologically dependent diseases of children. Thus, the overall system of program activities for the prevention of ecologically dependent diseases of children can be represented as follows: 1. Improving the legislative, regulatory, organizational, scientific-technical and economic base of prevention 2. Creation of an information base - a system of paired registers according to environment condition and population health of different territorial-administrative levels on the basis of monitoring of the environment and health. 3. Formation of high risk groups of children of ecologically dependent pathology. 4. Medico-prophylactic and medico-biological activities. Clearly, each block requires detailed work and linkages with other blocks. For some compounds, such as lead that carries a serious health threat to children there is a special program "Protecting the environment from lead pollution and reduce of its impact on human health" [81]. The materials above illustrate a complexity of the problem and the need for an integrated approach to its solution. To resource ensuring of such programs financial means of the federal budget are attracted as well as 16 means of the RF subjects, companies and organizations engaged in technological improvements, grants and funds aimed at solving the major humanitarian problems [81]. Conclusion A great number of literature devoted to the impact of environmental factors on children's health shows the actuality and diversity of the problem. Improvement of health or medico-ecological rehabilitation of children from areas of ecological trouble is the rehabilitation and expansion of children's adaptive capacities of an organism, increase of its resistance to multiple environmental factors and, in conditions of living in a city. To implement it to improve health or medico-ecological rehabilitation of children from areas of ecological trouble, it is necessary to create the conditions and implementation of a complex of measures aimed at protecting and strengthening children's health, broadening of their adaptive resources [21]. Despite efforts at different levels (federal, regional, etc.) and in different directions, there is no improvement of health of children’s population - statistics say quite the contrary. Worsening socio-economic status of large population groups requires a differentiated approach at working out and implementation of prevention and rehabilitation programs to various social groups including children, as well as taking into consideration socio-economic, environmental and climatic characteristics of a region. Taking into account the fact that the effect of harmful environmental factors is more active on the socially disadvantaged background, one of the priority is the task of not only medical but also social rehabilitation of children. For successful implementation of hygiene and preventive measures to reduce the influence of harmful factors on human health it is required awareness of population and preparedness of medical personnel, i.e. ecological and sanitary education and public education. It is also important cooperative efforts of scientists, physicians, ecologists, hygienists, a combination of theoretical and practical approaches for effective rehabilitation of children from ecologically unfavourable areas [90]. Medico-ecological rehabilitation of children living in zones of ecological trouble, should take into account specific harmful factors and severity of their consequences. So it is necessary to determine a burden of the most important toxicants, in particular, heavy metals, and diagnosis of pathology. On the base of the accurate diagnosis it is possible to develop a strategy and tactics of preventive and rehabilitative measures. 17 CHAPTER 2. MATERIALS AND STUDY METHODS The object of the study was the child’s population living in settlements of the Sverdlovsk (19 towns) and Tula (Novomoskovsk) regions, which are characterized as ecologically unfavourable territories. In the Sverdlovsk region examinations of children were conducted by two teams of pediatricians on two routes: the 1 st route included the towns: Revda, Pervouralsk, Kamensk-Uralskiy, Artyomovskiy, Bogdanovich, Irbit, Turinsk, Tavda, Cushva, the 2 nd route passed across the towns: Ivdel, Karpinsk, Sosva, Kachkanar, Krasnouralsk, Verhnya Tura, Nizhniy Tagil, Verhnya and Nizhnya Salda, Nevyansk. (The map of the Sverdlovsk region showing the towns where the surveys of children took place (Appendix 1). According to the State report "On the sanitary-epidemiological situation in the Sverdlovsk region in 2003" the most disadvantaged localities, from the point of view of the environment condition are towns included in the study: Nizhny Tagil, Kamensk-Uralskiy, Krasnouralsk, Pervouralsk, Revda, Bogdanovich, Artyomovskiy, Verhnya Salda, Irbit, Ivdel [25]. The surveys were carried out in the period of 2000 - 2003 by a visiting group of pediatricians, experts of a number of leading children's hospitals and research institutes of Moscow. Comprehensive survey was carried out: by a cardiologist, endocrinologist, gastroenterologist, neurologist, orthopedist, dermatologist, neonatologist, electro diagnostics experts. Along with outpatient examination the examination included both consultations and treatment of children in hospital. Epidemiological ecological examination included a comparative multigrop analysis of the results of clinical examination of children executed according to one methodological protocol. This examination was conducted by the search screening method. Patients with certain medical problems are usually exposed to this method. Contigents of children for the examination were formed in accordance with directives of local pediatricians who participated in this study. A preliminary briefing was conducted with doctors. It targeted them to select children on the basis of ecologically dependent disease: often and prolonged ill, chronically ill and children who need advice of narrow outline specialists as well as children with polisimptomatik that doesn’t not fit the nosological form. Administration and health authorities included in the examination of the towns participated in the organization of medical examinations of the child’s population. Mass media (press, TV) announced about conducting medical examinations of children and teenagers by a Moscow group of highly qualified doctors. In this regard, both children with the direction of medical institutions, and children whose parents decided to bring them to the survey themselves, came to the examination. It should be emphasized that the examined contingent was not representative to a children's population of the regions because it was a "condenced" selection with the predominance of children with chronic diseases. In the Sverdlovsk region in 19 towns in 2003, 3183 children of all age groups (from 0 to 17) were examined. The number of consultations was 5565. 18 In Novomoskovsk of the Tula region in 2000 medical experts examined 933 children of all age groups (from 0 to 17). The number of consultations was 1642. In the outpatient department of the Republican Children's Clinical Hospital (RCCH) of Moscow fifteen children with a diagnosis of bronchial asthma were re-examined, thirteen children were hospitalized for verification of the diagnosis. In the Tula region organization of medical examinations of children was carried out base on the Novomoskovsk Children's Hospital with the participation of local health authorities. The clinical examination consisted of examination of a child, study of a history of medical records and a survey of parents, consultations of other specialists when it was necessary. As a result of the examination "Health passport" was filled in. It included: passport data (name, surname, date of birth, address), information about parents (date of birth, education, occupation), extracurricular activities (participation in circles, sports activity and others), a list of previous diseases, information on medical examinations, recommendations on health improvement (residential treatment, hospitalization in a specialized medical facility, spa treatment, etc.) (Appendix 2). Then on the base of the examination the final diagnosis was formed, and recommendations for in-depth examination, treatment and preventive measures were given. Conclusions about a child’s health included the diagnosis (main and concomitant diseases). Assessment of a child’s health was conducted in the light of previous diseases, existing chronic diseases, functional status of the leading systems, the level and nature of functional and mental development (questionnaire in Appendix 3). In the Sverdlovsk region in addition to a comprehensive clinical examination, 953 children were examined using vegetative resonance test (VRT) for prenosological diagnosis and evaluation of modified adaptive processes. Child's body hypersensitivity to heavy metals was determined. Vegetative resonance test (VRT) is one of methods of electro-punctural diagnostic which is a further development of electro-punctural diagnostic of P. Foll. It allows to carry out an integrated assessment of human health, revealing itself as changes in adaptive processes [52,53,54]. Electropunctural diagnostics were applied for examination of children in the Sverdlovsk region in the light of the preliminary hygienic characteristic of the towns were the children lived. This method is the result of synthesis and in-depth development of methods and electro-punctural and bioresonance diagnosis. This method is based on the correlation between changes of the electrically conductive properties of the measuring points and the functional state of the corresponding organs and systems. When interpreting the data obtained by this method, the standard terminology for this method of classification was used. The term "toxic encumbrances" means an indication of the presence of unfavourable factors of different nature: chemical, physical, biological, on the principle of "yes-no" [103]. 19 Usage of the method of VRT is shown for: 1) the integral functional assessment of organs and systems condition, 2) topical diagnosis of pathological process with the help of proper preparations 3) etiological diagnosis with the help of various nosodes. While forming diagnosis test data, computer processing, medical history and clinical examination were taken into account. In processing of the examination results the status of various body systems was etimated: nervous, cardiovascular, endocrine, digestive, respiratory, urinary. In all groups, an analysis indicating the content of toxic metals was carried out. All patients with positive reaction for mercury, lead, cadmium, chromium, molybdenum and cobalt were included in this group. The survey of children by the method of electro-punctural diagnostic (VRT) was conducted on the "Miniexpert-PK" apparatus using computer software of IMEDIS allowing, to determine the degree of damage of various organs (License № 99-03-000420 of 29 December 2005; Health Ministry of the Russian Federation approved for use in medical practice, № 99/96, 2000). 953 children were examined (children and teenagers aged from 1 year to 17). Taking into account the nature of the screening examination, a survey was conducted only on the control points of the examination with subsequent computer processing. When analyzing the results there were taken into account: the complaints of the child, the information obtained from the parents, the results of physical examination, specialists consultaions. It should be noted that for all methods of diagnosis there is an inherent mismatch between the sensitivity and specificity, i.e. an increase in sensitivity will be accompanied by a decrease in specificity. As a result of clinical examination were formed groups of children with high risk of chronic disease development and living in adverse social and ecological conditions. The children selected during the examination were sent to a commission to decide the issue of rehabilitation in the specialized sanatorium departments. First of all children with chronic main disease, living in adverse social and environmental conditions were selected. Sanatorium treatment of the patients was carried out in specialized departments of sanatoriums. Diseases were coded according to the International Classification of Diseases of the 10 th revision (ICD10). The prevalence indexes of all diseases and some of their types in examined groups were calculated. Processing of the resulting examination data was carried out using statistical methods (programs Excel, SPSS., etc.). 20 CHAPTER 3. Sanitary-hygienic / Characteristic of the Studied areas The factors determined the choice of children screening areas in this study were: the presence of sanitary-hygienic characteristics of the territories excluding an additional hygiene surveys, environmental adversity of territories [25, 26]. Hygienic criteria for choosing areas of children examination were as follows: • High multi-component burden of environment; • availability of substances of the first and second class of danger in the environment; • adverse health and demographic indicators that 2-3 times or more as big than the baseline in the republic (high morbidity including certain kinds of pathology); • active growth of cancer sickness rate (the Sverdlovsk region takes the first place in the Russian Federation according to cancer sickness rate level of children); • the need for highly specialized pediatric care to people living in remote from health centres areas. The selected areas that meet the above conditions included 19 industrial cities in the Sverdlovsk region with the presence on their territories, ferrous, nonferrous metallurgy and mining industries and the town Novomoskovsk of the Tula region - the centre of the "great" chemistry. Health problems are mostly related to environmental pollution defined by the negative impact of industry primarily ferrous and nonferrous metallurgy and automobile transport. Industry is responsible for more than 80% of the volume of pollutants coming into the atmosphere from all stationary sources recorded in Russia. Twothirds of the volume of pollutants are discharged by enterprises of electric power engineering, nonferrous and ferrous metallurgy, oil industry. Indexes of the emission of pollutants into the atmosphere in the Russian Federation included in the study of the areas in 2000-2002 are presented in Table 3.1. Table 3.1 Emissions of pollutants into the atmosphere in the Sverdlovsk and Tula regions in 2000-2002.

Persistent organic compounds: organochlorine pesticides, dioxins and dioxin-like compounds, polycyclic aromatic hydrocarbons (PAHs), have high toxicity, are resistant to degradation, are characterized by bioaccumulating, accumulation in ecosystems of water and land. 3.1 Sanitary- hygienic characteristics of the studied towns in the Sverdlovsk region. According to the official statistics, the Sverdlovsk region is among the regions of the Russian Federation, leading on account of the volume of harmful emissions into the atmosphere. Socio-hygienic monitoring data showed that in the Sverdlovsk region about 3 million people live in areas with unfavourable sanitary and hygienic conditions and are heavily influenced by various environmental stresses (chemical, biological, noise, radiation, etc.), which stipulates in its turn, a low level of the population health. According to the degree of influence on the level of the population health and population quantity affected by adverse effects, environmental risk factors are ranked in the following order of priority on ecologically unfavourable territories of the Sverdlovsk region (Table 3.2). Table 3.2. Ranking of the major groups of risk factors of the environment for health of the Sverdlovsk region population.

Negative impact on health has chemical contamination of drinking water (over 2,4 million are exposed to the effect), air (about 3,2 million people), soil (about 3 million) and food (about 1,6 million). The ranks of the risk factors of chemical burden: Chemical burden with drinking water ………………………………….. 1 Chemical burden with atmospheric air ………………………..……2 Chemical contamination of soil ……………………………….…….3 Chemical load with food ………………………………………….…….4 Table 3.4 Complex chemical burden on the population in ecologically unfavourable towns of the Sverdlovsk region in 2000 Area Air (Ksum) Soil Water 24 (Zs) (Ktox) Nizhniy Tagil 8.5 13.3 3.4 Pervouralsk 7.7 20.2 1.39 Revda 2.9 23.35 3.2 Kamensk-Uralskiy 2.6 9.42 2.2 Krasnouralsk 1.4 7.78 4.6 Ksum - the total index of air pollution (the permissible level at Ksum ≤ 1); Zc – the total index of soil pollution with substances of the 1 and 2 danger class (permissible level at Zc ≤ 16); Ktox - the total index of contamination of drinking water with substances, normalized according to toxicological indicator of unhealthiness (the permissible level at Ktox ≤ 1). Chemical burden on the population related to the quality of drinking water. The largest contribution (52.6%) to the pollution of water makes housing and communal services, 85% of the volume of wastewater do not meet normative standards. The average content of specific pollutants (some toxic metals, oil, nitrogen, etc.) in rivers Iset, Chusovaya, Pyshma is significantly higher than permissible levels, 6 major rivers of the area are included in the list of the most polluted water objects of the Russian Federation. Over 3.5 million people are provided with water from centralized water supply systems, of which about 2.4 million people use water that does not meet sanitary standards according to organoleptic indexes, and more than 1.3 million people – according to sanitary chemical (in particular organochlorines, a group of nitrogen, heavy metals, etc.). Another one million people use water for drinking from non-centralized sources and its quality does not meet hygienic requirements by sanitary - chemical parameters (organoleptic properties, nitrates, oil, etc.) in 30% of cases and epidemiologically dangerous – in 25%. Approximately 15% of centralized water supply sources do not meet sanitary rules and norms for water quality. The share of sources that do not have sanitary protection zones was 12,9% (1999 -11.4 %) in 2000. A critical situation for providing population with drinking water has been created in the surveyed towns: Irbit, Turinsk, Kamensk-Uralskiy, Pervouralsk where drinking water is often supplied according to a certain schedule. Chemical contamination of drinking water is the major of ecological and hygienic risks affecting people's health and demographic situation which ultimately causes significant economic damage and ultimately unnecessarily high social 25 loss. The main agents of adverse effects on human organism are organochlorine compounds that are formed during disinfection of drinking water with chlorine. Disadvantaged with respect to organochlorine compounds remain the towns of the region using surface sources for centralized water supply: Verhnya Salda, Kamensk-Uralskiy, Kachkanar, Krasnouralsk, Nizhny Tagil, Verhnya Tura, Ivdel, Pervouralsk, Revda, Tavda (Table 3.5).

The analysis results of about 2000 water samples from the of centralized water-supply and noncentralized water supply sources have shown that practically all the population of the area uses drinking water with low fluoride content that contributes to the high rate of tooth decay. Calcium excess and increased hardness in the underground sources of drinking water is observed in Artemovsk, Bogdanovich and Kamensk-Uralskiy regions, which increases the risk of urolithiasis, leads to a violation of water-salt metabolism state, early calcification of bones, stunted growth of the skeleton of children. More than half of the water supplies of serve water with high content of iron and manganese. Verhnya Tura, Irbit, Ivdel, Cushva, Turinsk are particularly unfavourable in this respect. Periodically there is an excess of residual aluminum in drinking water (Tavda etc.). It was revealed unfavourable influence on the health of the population using drinking water containing aluminum in concentrations of 5.0 mg / l for a long time1, in 2002, according to the estimation of risk to public health in urban areas of Nizhniy Tagil (Leninsky and Tagilstroevskiy), Pervouralsk (village Dinas and district Tehgorod), Krasnouralsk, Cushva, Sysert), it was found that the water route of priority pollutants takes by importance the 2-nd – 3-rd places. As a result of coming with drinking water: • fluoride - in low concentrations increases the risk of dental caries: for the last three years in average more than 1,5 million cases are registered among the population of the area; • high concentrations of calcium – increases the risk of urolithiasis, violations of water-salt metabolism, early calcification of bones, skeletal growth retardation of children; • increased concentrations of iron and manganese - promotes the development of allergic reactions, blood diseases, deposition of iron compounds in organs and tissues; • high doses of aluminum - increase the risk of hypertonia and disorders of the gastrointestinal tract. It is confirmed that prolonged consumption of drinking water containing aluminum in concentrations of 5.0 mg / l leads to increase of prevalence of anemia among the population up to seven times, cystitis up to four times, dermatosis - two times, in comparison with the areas where the aluminum in drinking water did not exceed 0.02 mg / l; • Arsenic – it is forecasted to 228 cancer cases (while maintaining the forecasted level of exposure during the whole life) among all population groups. And the highest risk is predicted in the cities, where water supply is organized from surface sources; 1 Residual aluminum in drinking water after coagulation refers to the second class of danger. 27 • Cadmium – it is forecasted damage to renal tubules and development of toxic nephropathy - about 4315 cases among the whole population at continuing exposure throughout life. Chemical stress associated with air pollution. The Sverdlovsk region ranks third in Russia's total emissions of pollutants into the air, due to highly concentrated industry in settlements, the presence of salvo and emergency releases at the unstable mode of production, lack and inefficient work of gas-cleaning equipment. Fuel-energetic and metallurgical complexes are making the greatest contribution to air pollution. There is worry because of an increase of gross emissions of energetic enterprises in connection with change of fuel structure (transition to high-zolnye types of solid fuel) as well as air pollution by automobile transport in large industrial centres. Over 80% (of emissions in Russia in general) of gross lead-containing industrial emissions into the atmosphere are from enterprises of primary and secondary metallurgy of copper and its alloys. Mentioned above enterprises are located in the Sverdlovsk region. That is why this problem is of particular significance for this region. The main contributors to air pollution are companies located in towns with the most unfavourable environmental conditions: Pervouralsk, Nizhniy Tagil, Kamensk-Uralskiy, Krasnouralsk, Revda. Large air pollutants: Revdinsk Hydro-electric power-station (HEPS) (21% of the regional emissions), Joint-stock company "Sredneuralskiy Copper Plant (4%) (Table 3.6) Total emissions of pollutants in some towns of the Sverdlovsk region in 1996 (tons) Towns From stationary sources Pervouralsk Revda 210,983 6,353 102,397 30,241 88,673 6,295 105,175 7,861 1,257 12,648 2,778 38,102 89,93 From vehicles In all Kamensk Nizhniy Tagil 14,208 225,191 Uralskiy Krasnouralsk Pervouralsk. The major sources of air pollution in the town are: Pervouralsk Pipe Works, Dinas, Heat Electric generating Station (HEGS), Hrompik, The radio-television Equipment Plant, Tubular Building Constructio’s Plant, motor transport. Priority air pollutants: dust, sulfur dioxide, carbon monoxide, 28 nitrogen dioxide, hydrogen sulfide, sulfuric acid, hydrogen fluoride, formaldehyde, phenol, lead, cadmium, arsenic. The number of people exposed to air pollutants was 135,400 people. Nizhniy Tagil. The major air pollution sources are the following: industrial works: Heat Electric Generating Station (HEGS), Uralchemplast, Lebyazhka sintering plant, boiler-houses, vehicles. Prior air pollutants: dust, sulfur dioxide, carbon monoxide, nitrogen dioxide, hydrogen sulfide, carbon disulfide, phenol, ammonia, formaldehyde, xylene, cadmium, lead, copper, hexavalent chromium, benzpyrene. The number of people exposed to the influence of air pollution are 349,000 people. Kamensk-Uralskiy. The main sources of air pollution are: Tube Works, engineering plants, industrial and domestic boiler-houses, motor vehicles. Prior pollutants: dust, hydrogen fluoride, solid fluoride, nitrogen dioxide, sulfur dioxide, benzpyrene, copper, nickel, hexavalent chromium, carbon monoxide. The number of people exposed to air pollutants was 176,847 people. Aluminum plants, are powerful sources of carcinogenic risks to people living in areas of their deployment. It was found that the composition of resinous substances released into the air with emissions of aluminum plants includes such carcinogensmutagens as chrysene, benzo (a) pyrene, benzo (a) anthracene, dibenzo (a, h) anthracene, carbazole. The total content of only these well-known compounds in the emissions of aluminum plants exceeds the content of benzo (a) pyrene to 10 times [78]. Krasnouralsk. The main sources of air pollution: JCS ‘Svyatogor’, a chemical plant. Prior pollutants: sulfur dioxide, lead, arsenic anhydride. The number of people exposed to the influence of air pollutants was 23900 people. Compared with other similar towns with large industrial enterprises Krasnouralsk is consided to be safe for air pollution but it does not quite correspond to reality. The fact is that the integral indexes are calculated on the basis of the results of laboratory control of atmospheric pollution load on the population. The main source of emissions into the atmosphere – Krasnouralsk Cooper Industrial Complex emitting lead, arsenic, copper, cadmium and other contaminants. It has a favourable position according to the wind rose with respect to the housing building of the town. In this connection an air pollution post control located in a residential area is outside the influence of the plant emission most of the year. Therefore the average concentration of impurities recorded at the post control, have values mostly below acceptable standards. At the same time during the investigation conducted by the enterprise and the health service of the town under the torch concentrations of harmful substances in its emissions are registered. They substantially exceed the limits determined for them and are among the largest in the region. It confirms the aggregate index (AIC). It is calculated on the basis of gross emissions into the atmosphere. According to this index the load of air pollution of Krasnouralsk in one of the largest in the region 0,3 THI/person (THI – technical hydrocarbon index). The report “On the sanitary-epidemiological situation in the Sverdlovsk region in 2003”, Ekaterinburg 2004, 116 pp. In Krasnouralsk on the background of stabilization of lead emission with industrial discharges of JSC 29 Svyatogor into the air (1999-161, 577 tons/year, 2000 – 161.436 tons/year). In realization only the organizational and technical measures and improvement to the town allowed to achieve environmental quality improvements. In 2000 the average lead concentration in the air of the town was two times lower in comparison with 1999 levels (0.00028 mg/m3-1999, 0,00014 mg/m3- 2000). In particular administrative and technical measures were conducted at JSC Svyatogor during 1997-2000. They were directed to reducing industrial emission into the atmosphere at the expenсe of reducing productivity at unfavourable weather conditions and wind directions to the residential area of Krasnouralsk. A similar situation exists in Revda. The main sources of air pollution in the city are SMP (Sredneuralskiy Metallurgical Plant), brickyard, boiler houses, vehicles. Prior air pollutants are dust, hydrogen fluoride, sulfur dioxide, cadmium, lead, nickel, copper, arsenic anhydride. The number of people exposed to the influence of harmful substances in the air was 60000 persons. Sredneuralsk Copper Smelter has a favourable position according to the wind rose with respect to the housing building of the town. As a result two posts of monitoring the atmospheric pollution are outside the influence of the plant emissions most of the time during the year. Emissions of SMP mostly have permanent negative effect on health and living conditions of the population of Pervouralsk, which is located in the downwind direction with respect to SMP. In this regard, according to the integral parameters of the atmosphere pollution load on the population in accordance with the importance of the indicators Revda is in the second group of ten territories and according to aggregate index (gross emissions) in the fourth place. Priority air pollutants of inhabited territories are the following: dust, sulfur dioxide, nitrogen dioxide, phenol, formaldehyde, benzo (a) pyrene, fluoride and hydrogen chloride, lead, manganese, cadmium, hydrocarbons, arsenic anhydride, hydrogen sulphide, nickel, fluorides , sulfuric acid. The analysis of the received data shows that the load of atmospheric pollution on the population of the surveyed areas slightly decreased in 2000. These areas are: Artyomovskiy, Verhnya Salda, Cushva, Krasnouralsk, Nevyansk, Revda). The decrease took place mainly on account of the content of dust, phenol, nitrogen dioxide, formaldehyde, sulfur dioxide, which form the general background of the air pollution of the populated areas at the expense of both enterprises and life providing objects of localities and motor transport. Speaking about specific substances typical for certain specific enterprises emissions an insignificant positive trend is observed in V. Salda (fluoride and chloride hydrogen), in Krasnouralsk (sulfuric acid). However there is a slight increase in the atmospheric pollution load on the population in Pervouralsk, Nizhniy Tagil. Impurities on the account of which there is an insignificant increase of their concentration in the atmosphere relate mostly as in the first case to substances that form the general background of air pollution, and they are also a part of industrial pollution of enterprises (dust, nitrogen dioxide, carbon oxide, phenol, formaldehyde, hydrocarbons). 30 To access the degree of influence of air pollution on the population and to rank areas of "risk" according to the complex effect of pollutants, it was calculated the index of relative complex load of atmospheric pollutants on the population (API), on the basis of the facts of the laboratory testing (Fig. 3.1). 10 9 API 8 7 6 5 4 3 2 1 0 Fig. 3.1. Air pollution index in the Sverdlovsk region towns. To access the degree of influence of air pollution on the population and to rank areas of “risk” according to the complex effect of pollutants, it was calculated the total index of air pollutants on the population (Ksum) on the basis of the facts of the laboratory testing (Table 3.7) as seen from the table: • Nizhny Tagil, Pervouralsk, Ksum > 5 corresponds to very high levels of air pollution, causing a dangerous impact on the population health, which requires urgent measures to estimate and manage the protection of air quality and population health; Table 3.7 Comparative data on the total load indicator of atmospheric pollution on the population (Ksum) in the surveyed areas Name of the territory Nizhniy Tagil Total index of air pollutants on the population (Ksum) 1996 г. 1997 г. 1998 г. 1999 г. 2000 г. 9,0 6,5 6,1 8,5 8,5 31 Pervouralsk 5,0 9,4 11,5 7,0 7,7 Cushva 1,0 3,8 3,4 2,6 1,7 Bogdanovich 5,1 2,8 2,9 2,9 3,2 Kachkanar 2,4 2,4 2,8 1,2 1,9 Verhnya Salda 1,4 4,3 2,6 6,5 4,5 Kamensk - Uralskiy 9,0 7,8 2,6 2,2 2,6 Revda 3,1 9,0 2,2 3,3 2,9 Artemovskiy 0,4 1,1 1,4 2,5 2,3 Nevyansk 0,3 0,6 0,6 0,4 1,1 Ivdel 0,3 0,3 0,3 0,3 0,6 • Kachkanar, Krasnouralsk, Cushva, Nevyansk - K sum. > 1 <2 corresponds to exceed the permissible levels of complex atmospheric pollution resulting in increased risk of negative effect on the population health, but is not critical for the population. • Ivdel - K Sum. <1, which corresponds to the permissible loads levels for the population. • Artyomovskiy, Bogdanovich, Kamensk-Uralskiy, Verhnya Salda, Revda- K sum. > 2 <5, corresponds to high level of air pollution and is the cause of additional risk to public health, requires active intervention to assess environmental problems and health management of residential areas air. Comparative data by aggregate index of complex load (AIC) show that in 2000 there is an increase of this index in Pervouralsk (Table 3.8).

It can be seen of these pollutants that they are typical for both separate enterprises emissions and general background of air pollution of residential areas formed at the expence of motor transport emissions and life providing objects. At the same time it should be marked a slight decrease of this index to 10 territories (Nizhniy Tagil, Verhnya Salda, Artemovskiy, Cushva, Kamensk-Uralskiy, Krasnouralsk). Typical impurities at the expence of which a load on the population in this index reduced are: suspended substances, nitrogen dioxide, sulfur dioxide, formaldehyde, phenol, which form the general background of the residential area and their change depends mainly on meteorological factors and weather conditions. Specific impurities, which provided a reduction of load on the population the most significant are: fluoride and hydrogen chloride, nickel, zinc in Kamensk-Uralskiy, iron, manganese, nickel, hexavalent chromium in Nizhniy Tagil, hydrogen chloride, marganese, copper in the Verhnya Salda, copper and zinc in Cushva, arsenic in Krasnouralsk. This index practically has not changed in comparison with the previous years in Bogdanovich, Kachkanar, Revda. For the total load index of air pollution on the population (K sum.) the situation is the same. There is some increase of the load on the population in this index in Pervouralsk, Bogdanovich in 2000. It is clear that the territories above are mainly in the list of the towns where there is an increase in aggregate index of complex load of air pollutants on the population (AIC). The data analysis presented in the table shows that there is a slight decrease of the load on the population in the index on four territiries (Verhnya Salda, Revda, Artyomovskiy, Nizhniy Tagil). Tables 3.7 and 3.8 analysis data showed that the most unfavourable territories in accordance with Ksum and AIC are: Pervouralsk, Nizhniy Tagil, Verhnya Salda. The same territories, including Kamensk-Uralskiy, have been in the list of unfavourable territories from the last 5 years. In 2002 the most unfavourable territories from the point of view of Ksum and AIC were: Pervouralsk, N. Tagil, V. Salda, Kamensk-Uralskiy, N. Tura, Cushva. 33 Krasnouralsk, Pervouralsk, Nizhniy Tagil take first places in areas ranking according to the sum of the coefficients of habitat contamination risk with arsenic, zinc and copper. The harmful effect of lead on human health is combined with the effect of other industrial pollutants (copper, cadmium, arsenic, sulfur dioxide, mineral dust). Chemical load connected with soil contamination of residential areas High anthropogenic load is the reason of soil pollution of populated areas, agricultural lands with different substances including substances of the 1st and 2nd rate of harmfulness (lead, nickel, cobalt, cadmium, etc.). In order to range region areas according to the degree of soil pollution with substances of the 1st and 2nd rate of harmfulness taking into consideration the number of the population, Regional Sanitary and Epidemiological Surveillance Centre calculated soil contamination relative index (Br) (Table 3.9) and soil contamination average total index (Zsum) of (Table 3.10).

High level of soil contamination of childcare establishments and schools was revealed on different territories of the Sverdlovsk region (table 3.12). Of 941 studies of soil samples for pollution by heavy metals, 39% do not meet the standards. High soil pollution by heavy metals was found in the V. Salda (100%), Tavda (100%), Pervouralsk (96%), Revda (65%), Sysert (62,5%), Krasnouralsk (50%), Kachkanar (40% ). Of 827 studies of soil samples for pollution by lead 24% do not meet the standards. High soil contamination by lead was revealed on the territories of Sysert (100%), Pervouralsk (92%), V. Salda (80%), Krasnouralsk (50%), Revda (50%). Of 701 studies of soil samples for pollution by mercury 3,7% do not meet the standards. High soil pollution by mercury was revealed the territories of Tavda (100%), V. Salda (80%).

In 2002 areas with extremely dangerous levels of soil contamination were Krasnouralsk with a dangerous level – N. Salda, V. Salda, Karpinsk. Pervouralsk (100%), V. Salda (100%), Krasnouralsk (100%), Kamensk Uralskiy (80%), Bogdanovich (66,7%), Kachkanar (40%). The role of soil as a source of secondary contamination of the surface layer of atmospheric air especially increases on these territories. That influences children’s health in their direct contact. A serious problem for the region remains the problem of storing and processing of industrial waste especially toxic. In the region there are practically no landfills for disposal and dumping of toxic industrial waste and municipal waste landfills in most cases are not able to take these species. Annually about 10 million tons of toxic industrial wastes are formed. Not more than 25% of them are neutralized and recycled. High soil contamination with cadmium was detected on the territories of Sysert (100%), Krasnouralsk (50%) (Table 3.13). Table 3.13 Soil contamination with heavy metals on the surveyed areas.

Of 637 samples tested in accordance with microbiological indexes 5,7% of samples do not meet the standards: of 4912 samples tested for the presence of helminths 3% of samples do not meet the norm. Of the 89 samples tested for radioactive substances, 18% do not meet the norm. Kamensk-Uralskiy, N. Tura, Irbit, Cushva, Pervouralsk, Bogdanovich, Sysert are the areas of highest risk. 40 Radiation dose load. More than 3,3 million people are exposed to the effect of radiation load. Increased individual load is typical for areas with high radon release. The main sources of collective dose of irradiation population are natural sources and medical researches. There were no direct effects from exposure of radiation factors to the population health in 2003. Nizhniy Tagil, Kachkanar, Irbit Karpinsk, Ivdel, Sysert, Turin, Nevyansk are territories with increased individual radiation loads, i.e. loads exceeding average regional. They are towns with high radon release. 3.2 Sanitary - hygienic characteristic of Novomoskovsk of the Tula region Novomoskovsk is a large centre of Russian-made fertilizers and other chemical products. There is a large deposit of stone gypsum, limestone, loam, near Novomoskovsk [9]. According to the resolution of the Council of Ministers of the RSFSR of 16 September 1990 Novomoskovsk was named among 43 towns of Russia as the town with tense environmental conditions where environmental protection measures should be a priority. In 1999 the total gross emissions into the atmosphere of Novomoskovsk from all sources amounted to 26,155.1 tons, of which 16,680 tons were industrial emissions, 9,475.1 tons (36,2% of the total amount of emissions) were emissions from motor transport. Compared with 1998, the gross air emissions increased by 920.4 tons. Total increase of emissions in 1999 in connected with increase of production output. At Novomoskovsk hydro-electric power-station emissions increase by 961.4 tons is due to increased delivery of heat energy, coal combustion, and also its quality lowering in sulfur content. The largest contribution to emissions of specific pollutants contribute: “Nitrogen” - ammonia - 1975.1 tons, hydrogen chloride - 378.4 tons, sulfuric acid - 40,5 tons; "Polymercontainer” - ethyl acetate 121,7 tons. 270.8 thousand tons of pollutants a year are caught at the enterprises of the town and 266.6 tons or 98.4% of them are recycled. The contribution of transport to total emissions is as follows: carbon oxide - 63.8 %, nitrogen oxides 13,3 %, hydrocarbons - 97,4 %, sulfur dioxide - 25,5 %. In Novomoskovsk of the Tula region emissions of harmful substances from stationary sources into the air amounted to 22,6 thousand tons in 1996, 15,4 thousand tons in 1997, 15, 4 thousand tons in 1998, 16.7 thousand tons in 1999, 15,5 thousand tons - in 2000, 11.8 thousand tons in 2001. 41 In Novomoskovsk emissions of harmful substances from stationary sources into the air in 2001 were as follows: carbon monoxide - 5,531 thousand tons, nitrogen oxides 0.541 thousand tons, sulfur dioxides 0.121 thousand tons, 0.99 thousand tons of hydrocarbons. Excess of maximum permissible concentration (MPC) in dust, nitrogen dioxide, hydrogen fluoride, hydrogen chloride, ammonia, phenol and formaldehyde were registered in Novomoskovsk (Table 3.14). Table 3.14 List of substances (excess of MPC) released into the atmosphere of Novomoskovsk of the Tula region Substance Substance emission, MPC Hazard class, Mg/m3 Excess of MPC t/year Dust 59,6 3 0,5 To 4 times Nitrogen dioxide 12,5 2 0,085 To 2 times Ammonia 5,4 4 0,2 To 3,7 times Hydrogen chloride 0,3 2 0,2 To 3 times Hydrogen fluoride 0,008 2 0,2 To 3 times Formaldehyde 0,006 2 0,035 To 1,7 times Phenol 0,001 2 0,01 To 6 times Air Pollution Index (API) in Novomoskovsk is 5,4. According to SHM with the participation of the Sysin Institute of Human Ecology and Environmental Hygiene of the Academy of Medical Science, studies of air pollution by organic compounds were carried out. The results showed that in the air of Novomoskovsk there is a large amount of organic compounds. 153 organic compounds were identified in all. The basic mass of them introduce hydrocarbons, aromatic 42 hydrocarbons, aldehydes and ketones which determine total concentration of organic compounds. For the majority of individual organic compounds (aldehydes, geksanal, chloroform, benzene, xylene, ethylbenzene, isopropylbenzene) excess of MAC in 2-18 times was observed [10]. Water Sources of Novomoskovsk Water supply of the city is realized at the expense of underground water sources. The water quality of these aqufers is characterized by a high iron content, high stiffness, low content of fluorine. The low content of fluoride in the water is evidence of its natural -deficiency in the environment and has a direct connection with the high incidence of dental caries among the population. However, it should be noted that for the last 3-5 years the level of fluoride in aquifers has markedly increased, although did not reach the hygienic optimum. If in the early 90-ies the fluorine content in drinking water was at the level of 0,10,3 mg / l, then starting from 1996 - at the level of 0,4-0,8 mg / l. The tests results of heavy metals and organic compounds content in drinking water show that there is a problem of pollution by heavy metals: strontium, cadmium, and to a lesser extent by lead and mercury. The presence of metals in various environmental objects give a ground to suggest that the contamination of drinking water by metals has most likely, natural type and is connected with mineralogical features of water-bearing rocks. We should also note a certain meaning of fertilizers used in agriculture in increasing environmental load on the environment by cadmium. For water purification from iron at the town municipal water supply there are iron removal plants. However a large distance of water intakes from the town and existing intermissions in water supply is contribute to contamination with iron washed away from water supply system. As a result the iron content in the guard network of the town increases to 0,5-0,8 mg / l. In 1999 as a result of revival production at the enterprises of the town 53,7 million m3 of polluted wastewater were thrown down into surface reservoirs, which is 4.3 million m3 more than last year. This increase hasn’t led to deterioration of water quality which is connected with efficient operation of disposal plants "Nitrogen". Water facilities are relatively stable in epidemic relation. It is confirmed by indicators of bacteriological water control. At the same time because of existing deficit of drinking water in the town, water is supplied to the population according to the schedule. The radiation situation in Novomoskovsk Since 1986, the territory of the Novomoskovsk region is located in the zone of radioactive contamination because of Chernobyl accident – the IVzone. Contamination of the Tula region including Novomoskovsk 43 was 37-185 kBk/m2.]. Iodine has the same concentration – 131 kBk/m2. The dominant factor of population irradiation from natural radiation sources is radon accumulating in indoor air (residential, public and industrial premises). Since 1997, the average density of radioactive contamination of the soil according to the data of State Hydrometeorological Committee does not exceed permissible levels [26]. The materials in this Chapter show that the level of anthropogenic impact on the environment and on the urban population of the Sverdlovsk region where children were examined is significantly higher than that in Novomoskovsk of the Tula region. Among Russian towns with intense environmental conditions, where environmental protection measures should be a priority in the 90th years of the 20 century Novomoskovsk held the 43d place (Soviet Ministry Resolution of the RSFSR of 16.09.1990). To some extent it can be regarded as a control area in relation to the mentioned towns of the Sverdlovsk region. 44 CHAPTER 4. EXAMINATION RESULTS OF CHILDREN IN THE SVERDLOVSK AND TULA REGIONS 4.1. EXAMINATION RESULTS OF CHILDREN IN THE SVERDLOVSK REGION In all, 3183 people were examined. The total number of diagnosed diseases was 6322. Most of the children had two or more nosologies. The sex ratio in the studied children's contingent was almost equal: 49.8% of boys and 50,2% of girls. The children’s age was from 13 days to 17 years 11 months. The main part of the examined children (about 40%) were children of school age. Approximately 20% were children of 4-7 years old, 5,5% - children under one year (Fig. 4.1.1.). 45 40 35 30 25 20 15 10 5 0 Boys Under a year 1-3 years 4-7 years 8-14 years Girls 15-17 years Age Fig.4.1.1.

The number of the examined children in these cities was 1389 when the number of diagnosed diseases was equal to 2890. More than half of the children had several diseases of different organs and systems. The prevalence index was 2080.6 per 1000 examined children. Pathology of the respiratory, nervous and digestive systems were in the lead of its structure (Table 4.1.1.). Table 4.1.1.

Chronic inflammatory diseases of upper respiratory tract dominated in the structure of respiratory pathology. In the structure of the prevalence of the nervous system diseases, the most frequent diseases were the following: vegetative-vascular dystonia (VVD), astheno-neurotic syndrome, neurocirculatory syndrome, neurotic reactions, neurasthenia. Totally, they amounted to 31,3% of the total number of children diagnosed with neurological disorders. The second, third and fourth places respectively were given to perinatal encephalopathy, hydrocephalic syndrome, convulsions and epilepsy (Table 4.1.2.). Table 4.1.2.

Typical complaints of first year children to a neurologist were about agitated restless sleep and arrested motor development; of children from 1 to 5 years old, respectively - bad behavior, disinhibition, poor sleep, of children older than 6 years old - headaches, frequent fatigue, hyperactivity and violation of attention, astheno-neurotic reactions. Among the examined children of the first year of life perinatal CNS lesion of varying severity was often found. In the course of a survey of mothers it was stated that the majority of children (78%) had a birth trauma, entanglement of umbilical cord, birth asphyxia, resuscitation in the neonatal period. A large number of children (34%) were born at the age of 30-32 weeks, weighing from 1900 to 2300 grams. Practically, children with such pathology were discharged home from a maternity home even without any recommendations to visit a pediatrician (Tavda, Irbit, Bisert). At the same time in larger cities (Kamensk-Uralskiy, Pervouralsk, Artyomovskiy, Revda) the majority of children were under the supervision of a pediatrician and neurologist and received appropriate treatment. In the course of a survey of parents it was stated that during the first year of life most children had a diagnosis of hypertension-hydrocephalic syndrome. Almost all children received the dehydration treatment, moreover in half of the cases without further examination. Parents of 2-6-year-old children more often complained of a "bad character", "tearfulness”, aggressiveness, sleep disturbances. A more detailed survey revealed that the vast majority of children in their history had a birth trauma, and nearly all children of the first year of life were observed by a neurologist. While analyzing the family situation it was revealed that the majority of problems were mostly pedagogical or social (inadequate or increased demands on a child, cruelty to a child, scandals and fights in the family). It was found that the lower the intellectual level of parents was the higher demands on a 49 child's behavior they presented. The most common diagnosis: "neurotic reactions" occurred in Tavda (14,4%), Turinsk (6,0%), Irbit (4,9%), Bogdanovich (8,5%), Bisert (8,8%), Revda (9,6%). The frequency of cephalgias was approximately similar in all towns and ranged from 3,6% (KamenskUralskiy) to 15,3% (Revda). The survey revealed that children with birth or traumatic brain injury history has cephalgias more often. Approximately one third of children were examined in the regional children's hospital (Ekaterinburg) and received supportive therapy. The examination revealed that the majority of children needed in-depth survey (REG2, EEG3, ECHO-EGV4, CT5, ophthalmologist consultation) for further diagnosis and choice of treatment. Children of all towns suffered from hyperactivity syndrome with attention deficiency and minimal brain dysfunction with a frequency from 4,8% to 7,3%. It is remarkable that parents of "advantaged" children more oten complained to the hyperactivity. They were concerned with forecast of morbidity and possible methods of correction. Astheno-neurotic syndrome of children accured in all towns. The main complaints of parents were tearfulness, depressed mood, susceptibility, weakness, heightened fatigue, passivity of children. However none of the children was consulted by a psychologist, psychiatrist or neuropsychiatrist. Most children were from "bad families" and had burdened obstetric history. Enuresis was diagnosed in all towns (from 1,2% to 6,3%), but in Pervouralsk 8% of children complained of bedwetting and only 15% of children were examined by a nephrologist earlier. In other cases the survey was limited only to the analysis of urine. Tic. hyperkinesis were observed in all towns (from 0,6 to 1,7 % of children). In 16% of cases they were combined with logoneurosis. It was found that most children had tic. hyperkinesis "debut" at the age of 5-7 years old, had seasonal exacerbations, were treated symptomatically, and only 5% of children were fully neurologically examined. Convulsive status occurred with a frequency of 1 to 7,9% in all towns. Almost all diagnosticated children were additionally examined (EEG, REG, ECHO-EGV), they were prescribed picked up medication. During the examination of children it was found at that among them neurologically healthy were only 7,1%. Most children who applied were in need of constant surveillance of neurologist and neuropsychiatrist, further in-depth examination and treatment. 2 REG - reoencephalogram EEG - electroencephalogram 4 ECHO-EGV – echoencephalogram of vessels 5 CT – computerized tomography 3 50 The structure of the prevalence of diseases of the digestive system of children living in different examined towns, was different. Pathology of upper gastrointestinal tract was noted most frequently (31-52%). First place is occupied by chronic gastroduodenitis, gastritis and functional dyspepsia. Among the stated pathology chronic gastroduodenitis has consistently high level: from 75 to 82%. Hepatobilliarno-pancreatic pathology was in the second place with significant differences in the towns (2741%). Among the clinical entities dysfunction of the gallbladder was most frequently diagnosed (82%), chronic cholecystitis (1-3%), chronic pancreatitis (1,4-2,6%) and chronic hepatitis (2,9-3,3%) were diagnosed less freguently. Among bowels diseases there are more common functional disorders (irritable bowel syndrome, chronic constipation - 95% of the total number of people with bowels disease). The most common pathology of children living in ecologically unfavourable territories of the Sverdlovsk region, are diseases of the digestive system, the characteristics of which are the early (preschool age) manifestations of nonspecific symptom complex: heaviness in the epigastric region, nausea, belching, rarer - pains after eating, etc. In the history of these children, as a rule, there is a similar pathology their parents have. Children having family predisposition to gastropathology acquire it at an early age because of prolonged xenogeneic sensitization. A child receives from his mother some predisposition to a disease, and implements it under the influence of adverse environmental factors. Hereditary diseases are revealed under the influence of adverse environmental factors. It is a complex reason for formation of pathology in ecologically unfavourable territories. It is known from literary data and own observations that gastrointestinal problems are often combined with psychoneurological, such as neurocirculatory asthenia, neurosis-like states and neurasthenias, minimal brain dysfunctions and hyperexcitability, consequences of natal injury [Ursova]. Children in Irbit are of special concern. In this town psychoneurological pathology was diagnosed 2-2,5 times oftener than it had children living in other localities of the studied area. In-depth survey showed that all patients suffering from disorders of gastrointestinal tract had an astenoneurotic complex of complaints. Namely: deterioration of sleep, anxiety, malaise, unexplained weakness, headaches, lower progress in studies, unmotivated subfebrilitet, etc. In addition, trophic disorders are marked: decrease in elasticity and dryness of the skin, dystrophic changes of hair and nails, periorbital cyanosis, the phenomenon of vegetative dystonia. The mentioned above pathology of these organs and systems fits the symptom complex, which, in our opinion, may be a result of prolonged anthropogenic impact and follow-toxic sensitization of a child's body. The data analysis derived from the comprehensive survey showed that a large number of children (81%) living in towns Sysert and Bogdanovich, along with acute respiratory-viral and children’s infections 51 suffered from acute intestinal infections. In the surveyed region there was a high percentage of children suffering from helminthes and parasitic infections (opisthorchiasis, ascariasis, toxocariasis, giardiasis). So, helminthiasis are observed among children aged from 4 to 7 - 41%, from 8 to 14 - 36,2% and 3% of children and teenagers aged 15 and older (Figure 4.1.7). Salda takes the first place in the infestation 19,1%, then Nevyansk 16,2% and 15,6% Cushva. The clinical case of a child suffering from opisthorchiasis is shown in Appendix 4. 25 20 % 15 Boys 10 Girls 5 0 Under 1 1 - 3 years 4 – 7 years 8 – 14 years 15 years old old and older old old age Fig. 4.1.7. Age and gender structure of helminth infestation of children in the towns of the Sverdlovsk region. High infestation of children with different kinds of worms shows, first of all, a low level of communal and personal hygiene in the surveyed towns of the Sverdlovsk region. The same reasons underlie the prevalence of skin diseases of parasitic and infection type in combination with the revealed immune imbalance. A large number of pustular diseases was revealed in Kamensk-Uralskiy (26%), Tavda (22%), Turinsk (18%); in the settlement Bisert 13,6% of dermatological patients suffered from scabies. A low level of social and living conditions of the population (lack of hot water, natural gas supply in most homes and in the orphanage) in combination with the environmentally unfavourable situation clearly confirm the relevance of monitoring children’s health on environmentally surveyed areas. Children with endocrinopathy amounted to the following number from the total number of the examined children: in Nizhniy Tagil - 74%, in Krasnouralsk, Verhnya Toura, Kachkanar - 71%, in Sosva 62%, in Nevyansk - 61%, in Verhnya Salda - 59%, in Ivdel-50%, in Karpinsk - 39,5%. In the structure of the pathology of the endocrine system dominated euthyroid diffuse thyroid enlargement (88.2%), the genesis of which may be related to the combined effects of goitrogen of different nature: iodine deficiency, man-made chemical stress, immune disorders. The overwhelming number (up to 95%) were children with a small (first) degree of (WHO classification, 1994), thyroid gland enlargement. Children with the second degree of thyroid gland enlargement amounted to 5%. It should be noted a large number of children with pathological overweight (up to 7% of the total number of the examined 52 children), which is apparently connected with the unbalanced nutrition (insufficient intake of protein, vitamins against a background of plentiful intake of fats, carbohydrates). A small percentage of the examined patients (0,3%) were children with diagnosed pathology of genitals: Shereshevsky-Turner syndrome, Klinefelter’s syndrom, cryptorchidism, etc. Allergic diseases (exudative diathesis, food and drug allergy) were in the first place among the children of the first year of life as well as intestinal dysbiosis, lactase deficiency, enterocolitis. The absence in the history of parents and close relatives of similar allergic reactions may indicate acquired nature of the disease (no initial predisposition - atopy). In Cushva it was recorded a large number of children with various allergic disorders: pollinosis, bronchial asthma, allergic rinokonyunktivit, food allergy. The second and third place in allergic diseases occupied such towns as Verhnya Tura and Nevyansk. Neonatologist examined more than 400 young children (0-3 years old). Perinatal lesion of the nervous system of hypoxic, traumatic, infectious genesis with a lot of clinical syndromes of early and late recovery periods was the leading sickness of children under 1 year of life. The leading was the syndrome of intracranial hypertension. Pathology of the digestive system is in the second place according to the frequency. As a result metabolic diseases with a primary infringement of phosphorus – calcium metabolism (rickets) (because of lack of competence of ante – and post-natal prevention, malnutrition of mothers and children) are in the third place in the same category of children. Children of 1 - 3 years of life were diagnosed with a wide range of different kinds of pathology. It should be emphasized a high frequency of pathology of ENT organs as a result of breaking of the mechanisms of anti-infectiveprotection of this group of children (first place). In the second place there was a - pathology of the gastrointestinal tract. In the third place there were deviations in the development of neuropsychological functions (arrested development, abnormal syndromes). It should be emphasized that children often had a multiple organ pathology - affection of several organs or systems. More than half of the children have several different pathological states (clinical case of a child suffering from multiple organ pathology is shown in annex 5). In Figure 4.1.8 is shown the proportion of multiple pathology of children in different towns of the Sverdlovsk region. First place takes Cushva, in which 56% of the examined children suffer from several diseases, among which pathology of the nervous system in combination with diseases of ENT organs and the endocrine system predominate. Then comes Nizhniy Tagil (55%), where the leading pathology is also diseases of the nervous system in combination with the pathology of the ENT organs. Krasnouralsk is in the third place (54%). Pathology of the respiratory system in combination with diseases of the nervous system and gastro - intestinal tract dominate in this town. And, as a rule, the affection of the digestive system (in particular, biliary dyskinesia) is combined with symptoms of vascular dystonia. Such combination is regarded as an organ 53 manifestation of vegetative-vascular dystonia. Endocrine pathology is combined with the pathology of the menstrual cycle, height violation. Allergic syndrome is often accompanied by enlargement of the thyroid gland. It’s taken into account the presence of concomitant severe pathology of early-age children. 60% 50% 40% 30% 20% 10% 0% Fig. 4.1.8. Proportion of multiorgan pathology of children in the cities of the Sverdlovsk region. When examining children from one family it was revealed that brothers and sisters in the family had identical diseases. 175 children from 84 families were examined in different towns of the Sverdlovsk region (Annex 6). Families in which children were healthy, constituted 13,1%; families in which children suffered from various diseases constituted 47,6% of cases. It’s taken into account the high percentage of families (39, 3%), in which brothers and sisters have an identical pathology. In one family more often (about 40%) children suffered from the same ENT diseases (chronic tonsillitis, sinusitis, pharyngitis, adenoiditis). In 30% of cases in one family, both brothers and sisters had diseases of the digestive tract (biliary dyskinesia, gastritis, cholecystitis, dysbacteriosis). Endocrine diseases (euthyroid goiter) of children from one family were observed in 27% of cases. Brothers and sisters in one family in 12% of cases had allergic diseases (atopic dermatitis) and diseases of the nervous system (perinatal encephalopathy, vegetativevascular dystonia). A child inherits a predisposition to a particular disease, and implements it under the influence of adverse environmental factors in his early childhood because his family lives in adverse environmental conditions. Proceeding from the given data, we can assume that the same nosologic forms of diseases of children in one family have the same cause and indicate the existence of a etiotropic factor for a long period of time. 54 4.2. Children examination using bioresonance diagnosis method. As mentioned above, one of the objectives of this study was to study the information content of noninvasive bioresonant diagnostic method - vegetative resonance test (VRT) for screening of "toxic loads" in conjunction with clinical examination of children living in conditions of high man-made pollution. This method was used for early diagnosis of pathological abnormalities in children's health. Moreover, it seemed appropriate to use bioresonant method both in combination with other clinical methods, and as an independent method allowing to reveal a risk group on the basis of found changes. For this purpose, together with pediatricians of various specialties, as indicated above, experts of bioresonance diagnosis examined 953 children aged from 11 months to 17 years old. The total number of examinations was 2490. When analyzing the results of the survey both a patient’ complaints and those complaints which were made by his parents, as well as clinical observations in the form of external examination, the patient's response to the examination , and so on were taken into account. When making a diagnosis, the history and clinical examination data testing, computer processing were taken into account. When processing the research results it was carried out a synthesis of the major diseases of body systems: nervous, cardiovascular, endocrine, digestive, respiratory, urinary, ENT-organs, etc. It is accepted that in carrying out studies to determine the diagnostic capabilities of the new method (in this case VRT) results obtained with its help, are compared with the results of referential method (in our study - a set of modern diagnostic methods used for making a clinical diagnosis). A number of diseases diagnosed clinically and with VRT use are presented in Table 4.2.1. The coincidence of diagnoses made during clinical examination and VRT was 74.4%. 55 Table 4.2.1 Comparative data of children’s examination with methods of clinical diagnosis and bioresonance method (VRT) (absolute number of children) Pathology Clinical Diagnosis Diagnosis VRT Respiratory system 238 168 Nervous System 205 151 29 19 167 121 30 19 280 207 Helminthic invasion 92 68 Allergic diseases 41 28 Bronchial asthma 22 16 Healthy 74 80 1178 877 Cardiovascular system Endocrine system Urinary system Digestive system Total The main parameters that characterize the diagnostic significance of the screening method are its sensitivity and specificity. It should be noted that for all methods of diagnosis there is an inherent mismatch between the sensitivity and specificity, i.e. the increase in sensitivity will be accompanied by a decrease in specificity. In this case there are several possible options and to describe them a special terminology is used: a) true positive results (coincidence of the results of VRT research and the results of modern diagnostic methods with respect to establishing the existence of pathology); b) false-positive results (positive according to VRT and not identified by modern diagnostic methods); 56 c) false negative results (pathology is detected by modern diagnostic methods and is not detected by VRT); d) true negative results (absence of pathology is detected by VRT and by modern diagnostic methods). The following VRT parameters, characterizing the relationship between clinical results and those received with the help of VRT, using test points of measurement (Table 4.2.2) were obtained. When processing the data using the concepts adopted for the standardization of diagnostic studies. Table 4.2.2. Diagnostic parameters of the VRT method Parameter Sensitivity Definition The ratio of true positive results to the amount of true positive and % 72,9 false-negative results (percentage of patients revelation using the VRT method among the children whose disease is determined by clinical exanimations). Specificity The ratio of true negative results to the amount of falsepositive and true negative results (the percentage of revelation of healthy children among the contingent, determined at clinical studies as healthy). 33,8 On the base of the analysis of the results of the examinations and our own experience of applying VRT method, and taking into consideration the sensitivity (72,9%) and specificity (33.8%) of the latter, we can make conclusions about its definite significance and safety. Consequently, the adequacy of the method allows to recommend it as a method of noninvasive diagnostic for screening of toxic loads and formation of risk groups of children in ecologically unfavourable areas. As mentioned above, bioresonance diagnostics entails the use of the term "toxic loads". At the same time the adverse environmental factors with which a body can not cope, which aggravate its internal environment and are important to it are tested. Chronic toxic loads along with other factors lead to the weakening of the barrier functions of the body. Evaluation of environmental loads testing was performed in two directions. First, a positive test itself is a sign of absolute presence of tested loads in the habitat of the examined. And, secondly, a positive test is a sign of their damaging effect on the body. 57 The minutes of astimation of the impact of environmental factors included the definition of: loads by heavy metals salts (lead, cadmium, mercury chromium, molybdenum, cobalt) and total infectious sensitization. In addition, and other types of loads were analyzed: by petrochemical products, electromagnetic and radioactive exposures. However they turned to be less important and were not included in further processing of the material. The examined children in different towns had differences in frequency of toxic loads at different nosological forms of diseases. The frequency of these loads, determined by bioresonance technique method (VRT) at organic lesions of the central nervous system, diseases of the digestive and ENT-organs, endocrine diseases of children in the towns of the Sverdlovsk region (for 1000 examined) is shown in Figures 4.2.1, 4.2.2, 4.2 .3, 4.2.4. ‰ 1000 900 800 700 600 500 400 300 200 100 0 heavy metals common Fig. 4.2.1.

The frequency of toxic stresses in case of the endocrine diseases of children in the towns of the Sverdlovsk region (for 1000 examined). 59 Symptoms of pathological conditions of the examined children were diverse and, as a rule, characterized simultaneously presence of several diseases. So, on the background of the chronic infection of limphoid pharyngeal ring - chronic tonsillitis, adenoid vegetation, etc. - children suffered neuroendocrine pathology, often resulted in delayed development. In its turn, the immune imbalance in the body of the child supports fungal infection and parasitic infestation. Deficiency of minerals, micro elements, vitamins, enzymopathies is detected by this method of bioresonance diagnosis in the form of certain indicators - "toxic load". Thus, the combined data analysis of clinical examination data and results of bioresonans testing gives grounds to assume that certain types of pathology of children of the studied area were attributable to the relevant unfavourable background of the environment. 4.3 The results of children examination in Novomoskovsk of the Tula region In Novomoskovsk it was examined 933 children: 57% were boys and 43% girls. The greatest number of the examined belonged to the children of a school age - 8-14 years old (54%). The next largest group was the group of children of 4-7 years old (21%). At the age of 1-3 years - 13.5% of the examined % children (fig.4.3.1). 70 60 50 40 30 20 10 0 Boys Under 1 1 - 3 years 4 – 7 years 8 – 14 years old old old Girls 15-19 age Ris.4.3.1. The distribution of the examined children in accordance with age and sex Out of 933 examined 88 (9,4%) children had no diseases at the time of examination and were assessed as healthy. 76 children were not finally diagnosed because they needed a detailed clinical examination for its verification. The total number of illness was 1030. The prevalence rate was 1103.5 per 1000 examined children (Table 4.3.1). 60 Table 4.3.1.

The percentage of pathology of the organs of digestion and allergy was three times as small (Fig. 4.3.2). Among the examined children almost 30% of diagnoses accounted for diseases of the nervous system. The group with disorders of the central nervous system included not only 117 patients examined by a neurologist, but not less than 1 / 3 of patients taken by doctors of other specialties. Neurovegetative disfunctions, asthenic syndrome, masked somatopathy depressions predominated. Most often they manifested themselves in the form of vegetative-vascular dystonia (154 children). Among them 61 complaints for frequent headaches, increased irritability, neurotic reactions, sleep disturbance dominated. nervous system locomotor apparatus alimentary canal allergic 0.4 7.5 4 3.7 3.6 1.7 2.3 respiratory organs 29.4 10.9 26.4 10.1 cardiovascular system endocrine system ENT-system unitary system eyesight others Fig.4.3.2. The structure of the pathology of the examined children in Novomoskovsk. Thirty-four children were diagnosed with perinatal encephalopathy, manifesting itself in a small brain dysfunction (SBD), the consequence of hypoxia and mental retardation. In the examined group, with other diseases of the nervous system (115) dominated children suffering from neurosis enuresis (33), which raises the problem of psycho-emotional dysfunctions. In addition to the children with the listed diseases, among the patients who applied were the following diagnoses: convulsion syndrome, epilepticus status, child’s cerebral palsy, paresis, hyperactivity, etc. At the same time, differences were observed in the age structure in some of the above groups: among the children with vascular dystonia dominated students (almost 80%), and with perinatal encephalopathy - pre-school children (70%). It is clear that the consequences of perinatal encephalopathy begin to affect already in infancy. Age and gender structure of children suffering from diseases of the nervous system, did not significantly differ from that among all the examined children (Table 4.3.2). 62 Table 4.3.2. Age and gender structure of the examined children with diseases of the nervous system.

Perhaps it is developed on the ground of environmental and emotional stress. The second largest was the group of children suffering from diseases of the musculoskeletal system (272 people). Among them the most common pathology was the syndrome of connective tissue insufficiency: different types of scoliosis - 59,2%, joint diseases, manifesting in the form of arthritis and osteoarthritis, 10% of children in this group were diagnosed with these illnesses. 23% of children had a pathology of the foot. 7% of children had diseases of the locomotor apparatus. These diseases were consequences of different kinds of injuries. 13,8% of children formed the group with another strain of the skeleton. Age distribution of children in the groups was identical. The largest number of children were at the age of 8-14 years old: from 52,6 to 66,8% in individual nosological groups. At the same time, mardek sexual differences in the groups of children with different pathologies were observed. For example, in a group of children with scoliosis a number of boys and girls did not differ essentially: 47.7% and 52.2% respectively. In the group of children with arthritis and arthrosis girls dominated: 69,2% against 30,8% of boys. In contrast, among children with the consequences of injury the vast majority were boys: 73.6%. 63 Among the examined children 104 (10,1%) had allergic diseases, among them there were 54 cases of bronchial asthma, 13 - allergies and pollinosis and 31 - atopic dermatitis. Among patients with allergic diseases there were mostly boys (67%) than girls (33%). Age distribution of children in these nosological groups was different: in the group of patients with bronchial asthma 28,5% were children at the age of 4-7 years old and 57,1% - 8-14 years old. Infants - children under 4 years old had atopic dermatitis (35% of cases). 15 children were sent for examination to the out-patient department of the Russian Children Clinical Hospital (RCCH). In general, these were children with asthma and related disorders. An important feature of the examined contingent is a large number of children with diseases of the musculoskeletal system, mainly scoliosis. In some cases diseases were neglected. Without questioning the qualifications of the Novomoskovsk Children's Hospital doctors, however it’s impossible to underestimate the support of Moscow specialists in the diagnosis of obscure cases. One girl with a cyst of the pancreas was urgently admitted to the RCCH, where she was operated on. It was given 12 more warrants for hospitalization in departments of clinical immunology, dermatoallergology, gastroenterology, X-ray-surgical treatments. These children required a highly specialized medical assistance in the RCCH, which they could not get in the conditions of Novomoskovsk. In the outpatient department of RCCH there were examined 15 children with asthma and concomitant pathology. In general, these were children with a moderate bronchoobstructive syndrome. It should be noted it was clear that attacks weakened when a child left for another district. In our opinion, this fact may to some extent characterize ecological dependence of this pathology. To assess a social status of families a selective interrogation of 426 mothers was carried out, which showed that two-parent families – (81.8%) predominated among the examined children. The vast majority of families (90.5%) lived in furnished apartments, 5,7% lived in private homes and only 3.6% of families lived in a dormitory. Among the examined children there was one child from an orphanage. Professional occupation of parents is one of the characteristics of the social status of the family. As was shown in chapter 1, harmful professional factors which parents are undergone at work may negatively affect the health of children. According to the interrogation, 25.6% of fathers and 14.6% of mothers were engaged in chemical production, a leading in Novomoskovsk. Among the parents there was fairly high share of unemployed: 17.1% of fathers and 24.6% of mothers. It should be noted, however, a fairly high percentage of unemployed parents. It is possible that this factor has, directly or indirectly in combination with other factors, unexplored in this work, a strong negative impact on the state of the nervous system of children. It should be noted in some cases, the passivity of parents in the case of admitting children to specialized hospitals of Moscow for in-depth examination and treatment. Even having address consultation about 64 50% of families did not bring their children for examination and treatment. This, in our view, can be explained not only by underestimation of severity of a child’s illness, but in some cases, financial failure of families. The apparent problem appears inability of parents in good time and actively respond to the illness of the child, to conduct the treatments and preventive measures, independently in time pay attention to the aggravation of the disease, which requires health education among parents. CHAPTER 5. Risk groups depending on the health of children and degree of environmental stress of their residence. Worsening of socio-economic status of large populations groups requires a differential approach to various groups when developing and implementing prevention and rehabilitation programs and taking into account socio-economic, environmental, climatic characteristics of the region. Among the factors that determined the choice of areas of children examination in this study were, including, environmental adversity of selected areas and significant differences of areas in the spectrum and intensity of impact on the population of man-made environmental factors, suggesting differences in their consequences. The study confirmed practical expediency of the done choice made. It’s fair to compare the received data among themselves, because the same organizational scenario and methodical approach to examination of children was used in all inhabited localities. A comparison of the data on the health of children in the Tula and Sverdlovsk regions suggests that the higher technogenic load with hazards to the environment in inhabited localities in the Sverdlovsk region influences the level and nature of the prevalence of pathology in children’s population. First of all it manifested itself in the fact that the prevalence of all diseases index of the Ural children almost 2 times higher than of the children of Novomoskovsk. There are special high differences in the prevalence of diseases of respiratory and digestion organs, endocrine and nervous systems pathology (Table 5.1).. Table 5.1 The prevalence of different types of pathology among the examined children in the Sverdlovsk and Tula (Novomoskovsk) regions (for 1000 examined) Diseases respiratory organs The Sverdlovsk region 464,0* The Tula region 118,1 65 nervous system 413,2* 324,7 digestion organs 365,0* 120,0 endocrine system 240,5* 40,9 musculoskeletal 118,8 291,5* allergic 78,5 111,4 cardiovascular system 67,7 45,0 urinary tract 56,9* 18,2 Total 2080,6* 1103,5 * - P <0,01 In the Sverdlovsk region more than half of the examined children had at the same time two or more diseases, more frequently concomitant pathology was observed (affection of several systems, organs), and, as a rule, affection of the digestive system combined with symptoms of vegetative-vascular dystonia. Allergic syndrome was often accompanied by an increase of thyroid gland. Among the most gross organ pathology there was also central nervous system affection, immune and endocrine systems, and the liver, burdened by adverse environmental and social factors of the region. The results of the analysis of age and sex peculiarities of the prevalence of diseases of the digestive system clearly demonstrate a progressive rise of the index at the age periods of 2 - 6 years old (51%) and % 11-14 years old (35%), i.e. during the most intense morphofunctional changes in childhood (Fig. 5.1). 45 40 35 30 25 20 15 10 5 0 Under 1 1 - 3 years 4 – 7 years 8 – 14 years 15 years old old and older old old age 66 Fig.5.1. Age structure of the prevalence of digestive system diseases among the children of the Sverdlovsk region. A study of the prevalence of gastroenterological diseases occupies a special place in the practial pediatrics, as the gastrointestinal tract is most vulnerable to the effect of toxicants of technogenic origin, being one of the major routes of heavy metals entering to the body. Consequently, a clear increase in the frequency of gastroenterological pathology of children living in areas with different levels of anthropogenic pollution, in the early and preschool age can be considered one of the peculiarities of the analyzed diseases. The above-mentioned age periods from the point of view of the formation of pathology of the digestive system should be regarded as critical, that should be taken into consideration when forming groups of risk and developing preventive programs. Every third child of preschool and school age is diagnosed as having diseases of the musculoskeletal system and connective tissue disorders. In the structure of these diseases the main place is occupied by incorrect posture (60%), scoliosis (8-10%), chest deformation (12-14%), flat-foot (23%). In some cities of the Sverdlovsk region (Verhnya Tura, Salda, Nizhniy Tagil), and in Novomoskovsk of the Tula region children with deformities of the bones, fibrous dysplasia, dysplasia of the joints, aseptic osteonecrosis dominated. This pathology can be characterized by syndrome of a connective tissue deficiency. This condition accounts for insufficient content in the connective tissue of a specific protein - collagen. Low amounts of collagen may lead to functional, and in some cases to serious organic changes, which lead a child to disability. In the first place - to hypermobility ("looseing") of joints, and as a result to subluxation of the cervical joints of children. The instability of the cervical vertebrae is often the cause of headaches, fatigue, inattention and, finally, asthenia of a child. Violation of posture, a formation of flatfoot pathogenetically are a consequence of the same processes as the emergence of noise in the heart, in other words, the emergence of MAHD syndrome (minor anomaly of the heart development) because of prolapse of the mitral valve. As a result of the integrated examination it is noted by experts and raises concern a number of children (up to 4% of total patients) with arrested physical and sexual development of both sexes, girls with menstrual dysfunction, the genesis of which requires further examination (consultation in that number of endocrinologist’, geneticist, etc.). It’s taken into consideration a high level of metabolic diseases with a primary infringement of phosphorus-calcium metabolism (rickets), which to some extent may be caused by insufficient correct ante-and postnatal prevention in connection with the low level of pediatric care, unbalanced nutrition of mothers and children. 67 The lack of modern methods of diagnosis of mineral metabolism in medical institutions of rural and urban level and timely therapeutic correction of these conditions can later adversely affect reproduction of the population. However, we can not exclude the influence of social factors (lack of sufficient quantities of food rich in proteins and vitamins due to many reasons, the dominanting of which are low social level of the population), lack of educational activities and the promotion of healthy lifestyle. It should be noted that child’s health services in rural area are presented very poorly - quite often a doctor’s assistant gives help to children, there are no medical specialists. At the same time in larger towns where there is a pediatric service, children are rather well examined. Therefore, their examination turned into a detailed consultation. A comprehensive examination has revealed the main "critical" points. 1. It’s revealed the presence of organic pathology of the central nervous system, delayed mental development of children, which may be caused by many factors, the dominant of which are man-made disasters, industrial accidents, radiation. 2. Children with endocrinopathies ranged from 40-74% of the total number of the examined children. In a large percentage of these cases (up to 95%) an increase of the thyroid of the first degree, was registered. It’s stipulated by the combined effect of goitrogen of various origins: natural iodine deficiency, manmade chemical load, micro element imbalance, immune disorders, low doses of radiation. Children with the 2-nd degree of the thyroid increase (WHO classification, 1994) amounted to 5%. It’s necessary to carry out differential diagnosis with autoimmune thyroiditis, which requires more detailed examination (clinical ultrasound of the thyroid gland, hormonal spectrum, which includes the study of antibodies to thyroglobulin, tiroksinpiroksidaze, TSH, T3, T4). 3. Perinatal CNS lesions occurred with similar frequency in all towns. Minimal brain dysfunction, which manifested itself usually in the form of headaches, weakness, sleep disorders, etc. also took place roughly equally in all towns. In the history of children with a small brain dysfunction, there was usually a birth trauma or traumatic brain injury (concussion of the brain). Neurotic reactions, which manifested themselves in the form of disinhibition (aggressiveness), on the whole are peculiar to children under 6 years old. 4. Among the systemic diseases first place in the structure of the pathology occupy functional disorders of hepato-biliary system, the second, respectively - a violation of the genitourinary system: urinary tract infections of various etiologies in a case-history, neurogenic bladder, enuresis, dysmetabolic nephropathies, violations of salt exchange. Attention was attracted to identifying a large number of children of a younger age group (0 - 4 years) revealed by specialists. The children suffered 68 undifferentiated connective tissue dysplasia, manifested itself in weakness of ligamentous apparatus, a violation of posture, flat-foot, hypermobility of joints. 5. Most of the children of different ages had both in their case-history and at the time of the examination symptoms of chronic infection of lymphoepithelialny pharyngeal ring: chronic tonsillitis, adenoid vegetation, etc. In its turn, the latter aggravate, and in some cases determine the immune and endocrine imbalances, a manifestation of what serve developmental delay, chronic inflammatory diseases, allergic reactions. As a rule such children were often and for a long time ill and were carriers of viral and fungal infections. 6. Presence in the studied region a high percentage of children suffering from acute intestinal infections (81%), various pustular diseases (18-26%), fungal infections of the skin (23%), helminthes and parasitic infections (opisthorchiasis, ascariasis, toxocariasis, giardiasis (16 - 20%), scabies (13.6%) also confirms that they have immune imbalance. It can not be dismissed a low level of municipal conditions of the populations of the region and lack of health education of local health and sanitary-epidemiological service. The structure features of child’s pathology in the surveyed towns of the Sverdlovsk and Tula regions show the specifics of the spectrum of environmental hazards and their effects on the organism of a child. In different towns there was their a typical for them structure of the diseases, when individual nosological forms took place more frequently and was drawn some "environmental portrait" (Table 5.2, 5.3).

In Nizhniy Tagil an "environmental portrait" of a child is represented with the respiratory system pathology, organic lesions of the central nervous system (perinatal encephalopathy, hypertensivehydrocephalic syndrome, delayed psychomotor development, episindrom, muscular dystonia with a predominance of hypotension), an increase of thyroid gland (euthyroid goiter), congenital heart failures, myocardiopathy. In Krasnouralsk there are precisely more children with pathology of the upper respiratory tract (chronic tonsillitis, chronic sinusitis, chronic pharyngitis, adenoiditis) and digestive diseases (chronic gastro duodenit reactive pancreatitis, biliary dyskinesia). Table 5.3. Leading Industry (pollutants) and the main types of pathology of children in the surveyed towns.

In Bogdanovich underweight, often accompanied by disorders of the digestive organs and hypermobility syndrome joints syndrome dominated. It is noteworthy that children living in Bogdanovich had in nosological structure erosive gastroduodenitis (18,5%), complicated by gastrointestinal bleeding (3,7%). In Irbit there were more cases of thyroid enlargement, delayed physical development and vegetativevascular dystonia. It should also be noted that in 5.7% of children from Irbit gastroesophageal reflux disease was revealed. Moreover, the emergence of this disease accounts for 10-11 year old children. In Verhnya Tura more frequent were endocrinopathies (euthyroid goiter), multiple bone deformations with weak ligamentous apparatus (scoliosis, kyphoscoliosis, subluxation of cervical vertebrae, congenital habitual dislocation). In Salda an "environmental portrait" of a child is represented by functional cardiomyopathies and congenital heart diseases, perinatal encephalopathy with hypertensivehydrocephalic syndrome. In Artemovsk percentage of children with enlarged thyroid gland was maximum, as well as the widespread food allergy and of joints hypermobility syndrome. In Bisert relatively more frequent a joints hypermobility syndrome in combination with delayed physical and sexual development and food allergy was revealed. It was revealed a significant correlation between the API and the prevalence of neuropsychiatric diseases among the examined children, which can be supposedly caused by the presence in the air of neurotoxic metals (lead, mercury, manganese, cadmium, etc.). Environmental contamination by these metals is typical for towns with advanced ferrous and nonferrous metallurgy. The correlation coefficient between the air pollution index (API) and the prevalence of the nervous system diseases in the examined towns was 0.78 (p <0,04) (Table 5.4). For Novomoskovsk of the Tula region an "environmental portrait" of a child with diseases of the nervous system (neurovegetative dysfunctions, asthenic syndrome, hidden comatic depressions) and musculoskeletal system (incorrect posture, scoliosis, deformities of the chest, flat foot, arthritis and arthrosis) are typical.

Risk markers may be indicators of diseases prevalence, specificity of its structure, age-peculiarities of frequency of this or that pathology, the presence in a population of diseases associated with specific influence of harmful environmental factors, the overall unfavourable ecological situation on the studied area or the pollution of the environment components (air, water or soil), etc. It seemed expedient from this position to carry out the combined analysis of the received data. In the context of this task it is no less important a diagnosis of early adverse changes in health status which have not manifested themselves in the form of a specific nosology yet, but their revealation is important for preventing the subsequent development of a pathological process. However, according to WHO and the Health Ministry of the Russian Federation recommendations in order to prevent infection transmission preference should be given to noninvasive methods of prenosological diagnosis. The combined use of prenosological diagnosis methods and general medical examinations during the study of health status allows to diagnose groups of children with different level of health for a differentiated approach to bringing them into a healthy state. In this work such a noninvasive technique that gives the answer to the question, what is the load of heavy metals to the examined group of children was the VRT method. Evaluation of the relationship between environmental factors and health status and forming risk groups based on it requires, above all, a logical interpretation of the existing relations of qualitative signs and quantitative indicators of the environment state and public health. It is important to define the parameters of regional "norm of reaction" of a man to the effect of adverse factors [73]. Formation of high-risk groups, taking into account the action of harmful factors and pathological conditions caused by them requires the development of criteria, which depend on the specific hazard 73 (the content in the environment objects, ways of income, etc.) the nature of pathology, groups of children most exposed to its effect, etc. In the end, it defines the principles of clinic system, rehabilitation and prevention of environmental-dependent diseases of children. Onischenko G.G. with co-authors offered criteria for distribution of children for risk groups, taking into account the health status to determine a type and amount of specialized medical and preventive care [61] (Table 5.5). Table 5.5 Children risk groups and the type of specialized health and preventive care [according to Onischenko G.G. with co-authors., 2004] Risk Group I II Type of specialized medical and preventive care Practically healthy children (control Preventive set of activities aimed at activation of geral adaptive and immune resistant abilities group) of the body, held in organized children's groups.

Application of these criteria to the received materials allowed to form risk groups, which varied substantially as a percentage in different towns (Table 5.6). Table 5.6 Distribution of children according to risk groups in a number of examined towns. Towns Risk groups (%) I II III IV V Итого N. Tagil 11,8 20,0 15,6 20,3 32,3 100 V.

The coefficient of Kendall rank correlation of percentage of children classified in the high-risk groups with the general air pollution (API) is equal to 0.8 (P <0.05), i.e. to some extent they reflect the ecological stress of the territories where they live. The analysis of the health status of children residing in regions of high industrial load, has shown that a special group of children was formed at ecologically unfavourable territories. This gourp can be 75 considered a risk group. These children suffer maladjustment syndrome, have multiple organ pathology, which is undoubtedly the result of the influence of man-made environmental factors. The results of the work and conclusions of medical specialists confirmed the rationality of the compiled program of the comprehensive survey to identify the earliest symptoms of diseases of children from areas of high technogenic loads. The comprehensive examination was carried out by doctors of various specialities, including a neonatologist, neurologist, gastroenterologist, cardiologist, otorhinolaryngologist, endocrinologist, dermatologist, orthopedist. Taking into account the specificity of the effects of environmental factors on specific areas, it is possible attraction of physicians of other specialities that will contribute to active identifying environmentally-dependent diseases. It’s obvious that there is need for creation targeted prevention programs of child’s morbidity in the light of existing environmental and social situation, involving a wide range of medical specialists and the mass media. Lack of awareness of the specific of the harmful ecological factors which are peculiar to a certain area, puts the question of purposeful propaganda of scientific knowledge on this problem among the medical staff and people living in the zone of high technogenic loads. 76 CHAPTER 6. MEDICAL-ECOLOGICAL REHABILITATION OF CHILD’S POPULATION from environmentally unfavourable zones The results of the ecological and epidemiological studies have shown the need for rehabilitation of children living in areas with high stress. In order to get this goal there has been developed a comprehensive program of rehabilitation of children from risk groups, aimed at prenosological diagnosis, early diagnosis of diseases, prevention of complications. Center for Health ekorehabilitation "Green House" is the structure of the Federal Environmental Fund of the Russian Federation, engaged in health problems of children and adolescents. "Green House" is some kind of a laboratory for testing new modern methods of rehabilitation and strengthening the health of the younger generation and transferring this experience to all regions of the Russian Federation. The program involves the interaction of Centre for health ekorehabilitation "Green House" and the Russian Children's Clinical Hospital (Moscow) with the administrative offices of areas of ecological trouble. "International Children's Center”, the Sysin Human Ecology and Environmental Hygiene Research Institute of RAMS. Financing of this program was provided at the expense of the Federal Ecological Fund of the RF, extrabudgetary funds, as well as sponsorship funds within the limits stipulated in the program “Sanatorium rehabilitation of children from areas of ecological trouble, suffering from chronic diseases for 2000 - 2002". This program realization consists of the following expenses: the draft development of the sanatory rehabilitation of children, development of the protocol of children’s examination with high risk of diseases development, training of sanatoriums departments personnel; holding organizationalmethodological meetings. To provide successful rest and rehabilitation of children from Novomoskovsk of the Tula region, cooperation agreements with the State Enterprise "International Children's Centre were concluded. The Centre has long experience of sending children to holiday homes and camping sites, with the Republican Children's Hospital, as well as the organization “Hematologist’s of the world to children". The comprehensive target program of medical and ecological rehabilitation included prevention of diseases, proper medical care and was based on the following principles: • differentiation - the selection of children for health institutions depending on the state of health of the child and the profile of health institutions; • stages - consistent implementation of health activities in accordance with the state of health of the child; • continuity - the recovery should begin before a child enters a summer institution and continue after his return to his permanent living conditions; 77 • complexity - recreational activities should optimally include various factors (nutrition, training, psychological methods, herbal medicine, etc.). The program of sanatorium rehabilitation of children from areas of ecological trouble is aimed at creating a recovery system based on the selection of patients according to unified criteria of screening examination of children living in areas with high industrial loads. Unified system clinical examination hospital – sanatorium provides: 1. to identify groups of children with high risk of disease development; 2. to examine sick children for determining the quality of compensation of underlying disease, presence of complications; 3. to choose in accordance with medical evidence the most suitable conditions for the rehabilitation of the child; 4. to carry out a set of measures to prevent diseases. The purpose of the examination was to identify children with a high risk of a disease, to determine the degree of its compensation and to prevent complications. Particular attention was paid to examination of brothers and sisters with identical pathology and residing in the same family. To achieve this goal: the Passports of Health were developed; a unified system of selection of candidates for rehabilitation was created; Based on the examination groups of children with high risk of disease were formed; protocols of rehabilitation of sick children in accordance with the nosological form and degree of severity of the pathological process were develop; a system of evaluating the effectiveness of rehabilitation was developed; a method of training patients and their parents in the “Schools of self-control” was developed. The program was tested in Novomoskovsk of the Tula region with experts of RCCH (Moscow). As a result of the examination it has been carried out: 1. Distribution of children to risk groups for further examination Children with neglected latent forms of diseases were revealed, with indeterminate diagnosis accurate diagnosis was made; Children with indeterminate diagnosis were sent to additional examination to specialized medical and diagnostic centres; 78 In accordance with evidence reasons, children were sent to hospitalization to specialized medical treatment facilities. 2. Recommendations ground for medical-preventive maintenance of children. 3. Recommendations ground for further in-depth assessment of health status. The types and amount of specialized medical-preventive measures of 933 examined children of Novomoskovsk were determined in accordance with the distribution of the children under five risk groups, based on somatic diagnosis, taking into account the severity of pathological process (ris.6.1). Group I 25 % 230 children Healthful measures Group II 32 % 297 children Healthful measures At residence At residence Group III 13 % Group VI 20 % Group V 10 % 119 children Ambulant therapy 199 children Hospital treatment 88 children Hospital treatment City Hospital Republican Children’s Clinical Hospital City polyclinic and RCCH polyclinic Sanatorium-spa rehabilitation 673 children Sanatorium dispensary At residence in a green zone 246 children Sanatorium treatment at climatic health resorts 427 children Ris.6.1 Medical and preventive care at risk groups of children from Novomoskovsk. 79 Sanatorium-spa treatment of children subjected to health and environmental rehabilitation was carried out in specialized departments of sanatoriums. Sanatorium staff was trained on the base of the dietetics department of RCCH. According to the preliminary medical examination results groups of children were organized and completed. Activities for their rehabilitation at the Center for Health ekorehabilitation "Green House", in rest homes, as well as in camps located in the ecologically favourable regions were panned. Their meeting and seeing off at airports of departure and arrival were organized. Children were placed in a summer camp. Trips, cultural events and, in addition, special events, with emphasis on environmental education were organized for them ((Annex 7,8). On their arrival at the place of the rest children were examined by pediatricians, orthopedists, vertebral neurologists, hematologists, physicians of functional diagnostics, reflex-therapists, endocrinologists, surgeons, neurologists, nephrologists, allergists, dentists. Recommendations based on surveys that are included in the “Passports of Health” were given to hosts directly in holiday homes and camps, as well as medical personnel who provided ekorehabilitation activities. Treatment and preventive measures aimed at reducing toxic loads and functional recovery of damaged organs were conducted. In order to improve child’s health the following types of medical and ecological rehabilitation were implemented: physical, climatic, psychological, etc. Physical rehabilitation. The use of physical rehabilitation programs and training of fundamentals of sport on the base of health institutions is the necessary condition for removal of psycho-emotional complexes that children with chronic illnesses suffer. In view of physical rehabilitation according to medical evidence children attended surgeries of massage and manual therapy, acupuncture, magnetoelectric laser puncture, solarium, light -, of water - and mud baths, where physiotherapy was implemented. In addition, children took broth herbal and inhalation in the study of herbal medicine. Marine bathing, as well as classes in the pool and medical gymnastic were conducted. Climatic rehabilitation. Beneficial effect of climatic factors on the body of a child helped to restore the acid-alkaline balance, to normalize oxygen deficiency, which ultimately improved the basic health indicators. Doctors-dietitians administered nutrition of full value, age-appropriate to the child and prone to allergic reactions, a reasonable attitude to starchy foods and sweets. Children took stable homeopathic complexes and drainage remedies of vegetable origin, multivitamin preparations, ageappropriate to the child and his loads. For the psychological rehabilitation of children according to a special training program of Health Center "Green House" theoretical and practical training in natural conditions were carried out with them. The main task of educational and environmental activities is to instil love and respect for nature as a source 80 of health and preservation of harmony on the planet. An integral part of the rehabilitation program is to develop children's understanding of healthy lifestyle and their ecological education. An educational program "Green House" including educational supplies and textbooks, designed for children of different ages was elaborated for this purpose. Figurative expression "Green House" is the name of educational courses system developed for the comprehensive school. It provides acquaintance of children with the world around them, their science and ecological education. "Green House" is an educational courses system provided with programs package, a set of text books and educational supplies. They are approved by the Ministry of Compulsory and Trade Education of the Russian Federation. The programs are included in the collections of programs for elementary school. Textbooks and a number of other educational supplies are part of the Federal set of textbooks for educational institutions in Russia (Annex 7). As part of the educational activities significant time was devoted to the development of children's understanding of how important it is to maintain their own health. A series of lectures for the formation of healthy style of life was given. Children were presented with specially prepared booklets on the subject (Annex 8). On children's return from recreation areas they were medically surveyed at their residence. It was noted that during the period of surveillance the children from the group of frequently ill children were rarely ill with acute respiratory infections: 30% of them suffered once every six months, and 50% once a year. Those who were ill once every three months stopped to be ill. In the group of children with chronic nidyses of infection (chronic tonsillitis, adenoiditis) there were no relapses during the current year. When preventive ENT examinations were carried out it was registered that adenoids of the treated children decreased to the first degree, and surgical treatment wasn’t required. In the group of children with the diagnosis: vegetative-vascular dystonia there was progress in studies, work capacity increased, sleep normalized, weight increased, complaints of headaches disappeared, a general favourable background appeared. After the recovery the children were out of the state of asthenia. Effective rehabilitation of the children at the climatic resort had a positive effect on the children suffering from atopic dermatitis. Their disease has been in stable remission for over six months . Health improvement of children suffering from asthma occurred seasonally: children with pollinosis to the pollen of flowering plants were taken at the flowering period to another climate. The principle of rehabilitation in this case is: climate change - an exclusion of allergen - the disappearance of attacks of breathlessness. The hormonic background of the children suffering from endocrinopathies (euthyroid goiter) was restored to normal (TSH, T3, T4), general state of health improved. While examining a thyroid gland with the help of ultrasound diagnostic a positive dynamic was registered. Hydrotherapy with mineral water provided favourable therapeutic effects to children with gastroenterological disorders. Ultraviolet insolation on the climatic resort leads to better absorption of vitamin D. Warm sea salt baths, quartz sand, massage 81 helped diathermy of a child's body, which led to an improvement of metabolic processes and positively influenced the musculoskeletal system. Evaluating of the effectiveness of rehabilitation was carried out by the analysis of feedback questionnaires, compiled in the sanatorium by medical staff and presented to the policlinics at residence on the return from health institutions. In 3 and 6 months after the rehabilitation measures had been carried out outpatient cards of children (Form 112) were analyzed. After the rehabilitation measures beneficial effect was evident judging by changing the ratio of children at risk groups - reducing the proportion of children in high risk groups, moving them with improved health to groups with more favourable health status. However, after 3 months there has been movement in the opposite direction, which in 6 months became more obvious. This illustrates the need for repeated rehabilitations measures in risk groups to the full rehabilitation of children (Fig.6.2). The program realization gave the following practical results: Children with untreated latent forms of diseases were revealed, with indeterminate diagnosis accurate diagnosis was made; Children with indeterminate diagnosis were sent for additional examinations to specialized diagnostic and therapeutic centres: 15 children with the diagnosis of: bronchial asthma and moderate tendency of bronchio-obstruction syndrome were examined in the outpatient % department of RCCH of Moscow; 60 50 40 30 20 10 0 I II III IV V Examination period Fig.6.2. The effectiveness of preventive medical care in high-risk groups of children of Novomoskovsk 82 According to medical reasons, children were sent to hospitalization to specialized medical treatment facilities: 13 children were hospitalized to the department of clinical immunology, dermatoallergology, gastroenterology, radiosurgical methods of treatments of RCCH for giving high specialized medical care, which they could not get in Novomoskovsk. One girl was urgently hospitalized to RCCH, where she was operated on in connection with cyst of the pancreas; In summer camps it was conducted medico-ecological rehabilitation of children (673 children) in accordance with the developed recommendation system (summer school sites and recreation camps of urban and suburban type, All-Russian children's health resorts on the Black Sea coast with a further assessment of health status); Consultations were given to the doctors of the medical institutions, on the basis of which the children were examined. "Manual on rational use of antibiotics, cough medicine and mucolytics to prevent excessive allergization” was given to the medical staff. The parents of the examined children were given recommendations concerning therapeutic and preventive measures in accordance with the child’s health and diagnosed pathology (Annex 8). Thus, analysis of the hygienic sanitary situation in the territories of the examinations, prenosological and clinical diagnosis of the health status of children living in conditions of high technological loads allow to identify groups of high risk of pathology, to determine appropriate conditions for the improvement of children’s health and to hold a set of preventive measures (Fig. 6.3). Environmental and living conditions estimation Hygienic, prenosological and clinical diagnosis of violation of children’s health Risk groups forming Working out of medical-preventive and recreative measures complex Hospital Policlinic Sanatorium Evaluation of medical-preventive and rehabilitative measures effectiveness 83 Fig. 6.3. An integrated approach to the development of therapeutic, preventive and rehabilitating measures of children with ecologically-dependent diseases. As a result, the carried out complex of medical and preventive measures includes all types of prevention of disturbance of children's health: • Primary prevention - the formation of a stable idea of a healthy lifestyle, observance of the day procedure, adequate nutrition, tempering procedures; • Secondary prevention - prenosological diagnosis of health status disturbances, identification and elimination of early symptoms of diseases, carrying out of recreation; • tertiary prevention - treatment of identified pathology, relapses prevention and chronic pathological process through the complex of medical and preventive rehabilitation measures. Governor's Special Purpose Program to provide medical assistance to children living on ecologically unfavourable territories is carried out in the Sverdlovsk region. To avoid duplication, rehabilitation of the examined children in the towns of the Sverdlovsk region was carried out under this program in accordance with medical evidence and the recommendations of doctors who conducted the examination [20, 82]. The methods of organizing and conducting recreational activities developed in this analyse, was also implemented in other regions of Russia (the Arkhangelsk, Moscow, Yaroslavl regions, Primorsky Krai, the Republics of Karelia and Khakassia) with the participation of the State Enterprise "International Children's Centre”, which is one of the participants of the federal special purpose program “Development of All-Russian children’s centres “”Orlenok” and “Ocean”. In 2001-2005 2638 children from these regions were sent for rest and medical-ecological rehabilitation to rest homes and sanatoriums. 84 CONCLUSION The analysis of the results of the comprehensive examination of the child’s contingent according to the program developed by us showed that on the studied territories in the zones of ecological trouble the level of skilled medical care provided for mass child’s population was insufficient. The examination of the children by medical specialists in many cases showed a lag of practical public health in provinces from modern methodologies developed and extensively published in the periodical medical press and at conferences. In order to detect early symptoms of diseases of children from areas of high technogenic load the above-mentioned comprehensive survey was carried out by doctors of various specialities, including neurologist, gastroenterologist, cardiologist, neonatologist, otolaryngologist, endocrinologist, dermatologist, orthopedist. Taking into account the specificity of the effects of environmental factors, it is possible to involve other medical specialists which will contribute to active identification environmentally sensitive pathology. It should be noted that this work on a survey of children was carried out with direct participation and active cooperation of local doctors to carry out the subsequent continuity during dynamic, postrehabilitation observation of the stated contingent. It’s obvious the necessity for creation of targeted programs for prevention child’s morbidity in the light of existing environmental and social situation, involving a wide range of medical specialists and the mass media. Lack of awareness about the specific of harmful environmental factors effect characteristic of a particular area raises the question of targeted promotion of scientific knowledge in this field among medical personnel and the public. An important aspect of environmental factors effect is children's mental health break down and therefore an urgent task of rehabilitation is psycho-correction to improve the emotional and personal sphere and the state of the autonomic nervous system. Taking into consideration the fact that the effect of harmful environmental factors more actively manifests itself on socially disadvantaged background, one of the priority tasks is the task of social rehabilitation of children. It is shown that the negative effect of harmful environmental factors on the body of the child more actively manifests itself on an unfavourable social background. Social gradient in the formation of children's health, identifying modern features of health formation, actually provides and determines the trends in health and qualities of future population of the country, the realization by this contingent of social and biological functions pre-determining the life and health of future generations [92, 31]. The data above show urgent need for solutions in the society of social problems related to livelihood of children, including these items in the strategic documents on development of the country and close monitoring of their practical realization at all levels [48]. The problem of children’s health breakdown is multifaceted. As the above data show, it focused imperfect legal regulation of children's health protection, negative effects of socio-economic changes in 85 the country, the ambiguity of organizational changes in the field of public health, etc. Since the problem is interagency in nature, for its integrated solutions it is necessary to attract structures of different profile and level from federal, regional to non-governmental organizations and funds that put the problems of public health protection. The decisive condition must be a systematic approach in which each block of the system is interconnected with the other components, has clear tasks and methods of their solution. Formation of high-risk groups, taking into account the action of harmful factors and pathological conditions provoked by them requires the development of criteria which depend on the specific of a harmful factor (the content in the environment objects, ways of income, etc.) the nature of pathology caused by it, groups of child’s population mostly affected by its effects, etc. In the end, it defines the principles of health centre system, rehabilitation and prevention of environmentaldependent diseases of children. Bringing into a healthy state should begin before your child enters a summer institution and it should continued after his return to the permanent conditions for him. In order to implement sanitary-hygienic and medical-preventive measures to reduce the impact of harmful factors on children’s health successfully it is necessary to inform population and medical personnel is to be appropriately trained, i.e. ecological and health education is necessary. 86 CONCLUSIONS 1. Priority risk factor for public health in the Sverdlovsk region on the basis of analysis of sanitaryhygienic state of the environment is a complex chemical and biological stress associated with pollution of water, air, soil, mostly marked in Kamensk-Uralskiy, Cushva, Pervouralsk, Revda, Krasnouralsk. In Novomoskovsk of the Tula region chemical stress is associated with air pollution. 2. In the surveyed towns of the Sverdlovsk region the prevalence of pathology of the examined children was significantly higher than of children of Novomoskovsk (p <0,01): the prevalence of all diseases, respectively 2081 ‰ and 1103,5 ‰, respiratory diseases (464 ‰ and 118,1 ‰ ), nervous system (413 ‰ and 324 ‰), digestive system (365 ‰ and 120 ‰). 3. Prevalence of child’s pathology and its structure in individual towns show the specifity of effects of environmental factors, creating a certain "ecological portrait" of a child characteristic of a particular town that may have diagnostic meaning in the formation of hypotheses about possible local factors responsible for the emergence of diseases in the area. Specifity of influence of to environmental factors should be considered in the formation of multidisciplinary teams of medical specialists to examine children from areas of ecological trouble. 4. It is advisable to use non-invasive method of VRT informative with regard to specific environmental factors effecting a human organism, for examination of large contingents both in conjunction with clinical methods and as an independent method of prenosological diagnosis. 5. The program of medical and ecological rehabilitation is to be based on the principle of continuity "clinical examination - hospital - sanatorium" that allows to examine children completely to identify groups at high risk of chronic diseases, qualities of compensation of the main disease, presence of complications and, accordingly, to recommend the most suitable conditions for recovery. 87 Bibliography 1.

Bykov REVIEW of the abstract of the thesis for the scientific degree of Candidate of Medical Sciences of V.A. Sobolev "The scientific basis of screening examinations and health measures among children living in ecologically unfavourable territories" - 14.00.07 - Hygiene, 14.00.33 - Public health and health care. The topicality of the problem is caused by health conditions of the population, high level of morbidity and mortality indicates the current crisis, the need for urgent actions to improve the health of the population (GG Onischenko, 2001). For the formation of risk groups and for adequate medical and preventive measures it’s necessary to take into account the relationship between child’s population health and environmental factors that are indicators of risk. It seems urgent to implement noninvasive methods of screening of diseases, allowing to involve a significant contingent of children. Scientific novelty lies in the fact that the program which has a comprehensive approach to the examination of the child’s population living on ecologically unfavourable territories was worked out for the first time. It is aimed at identifying children at high risk of ecologically-dependent diseases. The practical significance is determined by the fact that noninvasive method of bio-resonance diagnostics is informative which allows to carry out screening in the optimum periods; significantly reduce temporal and financial expenses both to detect early prenosological states and to confirm that pathological processes of the examined children are chronic. Organization of work, scope and examination methods fully meet the requirements made on the theses for the degree of Candidate of Medical Sciences.

"The scientific basis of screening examinations and health measures among children, living in ecologically unfavourable territories" , in specialities - 14.00.07 - "Hygiene" and 14.00.33 - "Public health and health care". Currently, the development of contemporary Russian society is characterized by the transformation of socio-economic, environmental, medical and biological conditions that undoubtedly affects the health of the population, including children. Children's health is influenced by a complex of factors, including environmental factors. In this regard, examinations on the health of children living in ecologically unfavourable areas are topical. The author in accordance with the purpose and objectives of the study used a complex of modern and adequate research methods that provide a reliable material. Selection and volume of the conducted researches are sufficient to carry out reliable statistical processing and to get conclusions. Development of a differential approach to the selection of principles of children’s health improvement is an important element of children's health. This is the first time rational methods of screening examinations, medical and environmental rehabilitation of children living in ecologically unfavourable territories of Sverdlovsk and Tula regions were scientifically based by the author. The results of the study have both research and great practical value. The material of the research is published in the form of 6 scientific papers and approved at 5-scientific-practical conferences. Thus, the thesis of V.A. Sobolev "Scientific basis of screening examinations and health measures among children living in ecologically unfavourable territories”, is an independent qualified complete scientific work, which contains the solution of an important scientific problem having great significance in preserving and improving the health of children, which meets the requirements of item 8 of the “Regulations on the procedure for conferring academic degrees” made on candidate theses, and its author Sobolev V.A. deserves the award of the desired degree of Candidate of Medical Sciences, speciality 14.00.07 - "Hygiene" and 14.00.33 - "Public health and health care."

"The scientific basis of screening examinations and health measures among children, living in ecologically unfavourable territories" , in specialities - 14.00.07 - "Hygiene" and 14.00.33 - "Public Health and Health Care". The thesis of Sobolev V.A. is devoted to the actual and practically important issue of preventive medicine - examination and health care of children. It is important to find out processes of the formation and identification of problematic situations, taking into account the ecological situation in several regions. During the examination the author developed and used the screening system of evaluation to identify ecological burden of health condition, which may affect the severity of the pathology manifestation. The more important are the results of the experiment conducted during the examination, when the instrumental method was used in conjunction with the results of the health examination by representatives of different clinical specialities which confirms its informative content and the ability to use for screening of sick children’s contingents. The received during the examination the author’s conclusion about the necessity of stages and succession in the provision of rehabilitation of children is important. At the same time it should be noted the need for a more rigorous attitude to those used in the research concepts, as "ecologically-dependent diseases”, ecopathology, because the spectrum of diseases that children suffer everywhere not only in the ecologically unfavourable territories is analyzed. A more rigorous attitude should be to the statistics - the author points out that the hygienic criteria for selecting areas of the examination were, in particular, higher levels of morbidity 2-3 times higher than national levels. The overall level of recorded morbidity of children in Russia in 2005 was 2,150.1% 0. Accordingly, it is unlikely that the author found the territories in the country where 3 times higher levels of morbidity of children (more than 6000%0) were registered. It is not enough valid the assertion about a higher proportion of children with congenital anomalies in Nizhniy Tagil in comparison with the average Russian level -the examined contingent in contaminated areas is not strictly representative, in general (as it is presented in the abstract) only sick children were sent for examinations and consultations of specialists, and among Russian children in general, the majority are healthy and practically healthy children. The peculiarities of the examined contingents can have an impact on the results of comparison of the characteristics of children's health at various bases of the study. We should also note the lack of rigour of data in Tables 3 and 4 compared with the information in the text, as well as the need for more strict (according to ICD-10) formulation of diagnoses, and group names of diseases. 121 However, it is very important that is the first time the author scientifically based rational methods of screening examinations and rehabilitation of children living in ecologically unfavourable areas by means of the example of the Sverdlovsk and Tula regions. Although from the positions of hygienists in the first place there is need for work on pollution prevention of areas where people live, the introduction of new production technologies. The list of publications reflects the content of the thesis. In general, appreciating the thesis of Sobolev V.A. "The scientific basis of screening examinations and health measures among children living in ecologically unfavourable territories," we must conclude that it is independent and completed research in the field of hygiene and public health, topical, is executed at the modern methodological level. Judging by its scientific and practical significance the thesis meets the requirements of item.8 of Higher Examination Board of the Russian Federation made for candidate theses, and the author deserves the award of the desired degree of Candidate of Medical Sciences in specialtities 14.00.07 - Hygiene and 14.00.33 – “Public health and health care”.

"The scientific basis of screening examinations and health measures among children, living in ecologically unfavorable territories" , in specialities - 14.00.07 - "Hygiene" and 14.00.33 - "Public Health and Health Care". Relevance of the study. Children's health determines the health of the country population as a whole. According to the official statistics, the disease incidence of child’s population is increasing annually by 45%. Significant contribution to the negative dynamics of child’s health is made by environmental factors. Therefore, to study the effect of these factors on children's health, development of methods for diagnosis of pathological conditions and health and environmental rehabilitation of sick children is an urgent task. The scientific novelty of the research lies in the scientific basing of technology for screening examination of children living in ecologically unfavourable territories. The practical significance lies in revelation of the influence of environmental factors on the disease incidence of children. The method of children’s rehabilitation is offered and its effectiveness is estimated. The developed methods of organizing and conducting recreational activities is implemented in several regions of Russia: Archangelsk and Moscow regions, Primorsky Krai, the Republic of Karelia and Khakassia, which indicates that the introduction of the results into practice. The work is presented on 140 pages of typewritten text, consists of an introduction, 6 chapters containing the results of own research, findings, conclusions, bibliography. Index of literature contains 135 works, including 103 domestic and 32 foreign authors. Illustrative material is presented in 6 chapters of the thesis, 27 tables, 20 figures, 7 applications. According to the results of the studies it was published 9 scientific papers, including a monograph and 2 articles in journals, recommended by Higher Examination Board. The object of the examination were children living in localities of the Sverdlovsk (19 towns) and Tula regions (Novomoskovsk): Total - 4,116 children of all age groups (3,183 children in the Sverdlovsk region and 933 children in Novomoskovsk). The examinations were carried out in 2000-2003 by a visiting group of pediatricians - some experts of the leading pediatric hospitals and research institutes of Moscow. The comprehensive examination was carried out by: a cardiologist, endocrinologist, gastroenterologist, neurologist, orthopedist, dermatologist, neonatologist, experts of bio-resonance diagnostics. Administration and health services participated in the organization of the medical examination of the child’s population of the towns. To assess the extent of toxic load on the body and the changes of adaptation processes of 953 children in the Sverdlovsk region, along with the traditional clinical 124 examination, the determination of the child's body hypersensitivity to heavy metals was carried out with the help of non-invasive method of bio-resonance diagnostics (VRT). The statistical processing of the material was carried out. The examination results. Non-invasive bio-resonance method (vegetative resonance test) is informative (with regard to specific environmental factors acting on the human body) for screening large contingents of children, both as an independent method of prenosological diagnosis and in combination with traditional clinical methods. Organization of rational complex screening examination of children living in ecologically unfavourable territories, allows to form groups at risk and to develop an adequate strategy for their rehabilitation and subsequent implementation. In the surveyed towns of the Sverdlovsk region prevalence of all diseases of children in general (2081%0 0) was significantly higher than in Novomoskovsk, and due to respiratory diseases (respectively 464% 0 and 118.1%0 of a nervous system (about 413%0 and 324%0) , digestive organs (365%0 and 120%0) (p <0,01). The prevalence of child’s pathology and its structure in individual towns show the specificity of the environmental factors that create a certain "environmental portrait" of the child, which may have diagnostic value in the formation of hypotheses about possible local factors responsible for the emergence of diseases in the territory. A program of rehabilitation of children from ecologically unfavourable territories has been developed with the participation of the author. 673 children from the surveyed in Novomoskovsk took, sanatorium rehabilitation. Evaluation of the effectiveness of rehabilitation was done by analyzing the feedback questionnaires, drawn up in the sanatorium by medical staff and presented to the polyclinics in residence after returning from health institutions. Outpatient medical histories of children (Form 112) were analyzed after 3 and 6 months after curative measures. The positive effect was evident from the change in the proportion of children in risk groups - reducing the proportion of children in high risk groups, the transition them to (in the case of improving health) groups with more favourable health status. However, after 3 months it was indicated movement in the opposite direction, which in 6 months became more manifestative. This illustrates the need for repeated healthful measures in risk groups up to the full rehabilitation of children. The conclusions of the thesis corresponds to the obtained research materials. There are no principle remarks in the work. Conclusion. The thesis of V.A. Sobolev, "Scientific basis of screening examinations and health measures among children living in ecologically unfavorable territories" is a complete independent examination in which 125 the use of screening examination and medico-ecological rehabilitation methods is scientifically proven. The work fully corresponds to the demands of item 8 of the “Regulations on the procedure of awarding scientific degrees”, approved by Government resolution of Russia № 74 of January 30, 2002, presented to the theses for the degree of Candidate of Medical Sciences, and its author deserves the award of the desired degree in specialities 14.00. 07 - Hygiene and 14.00.33 - Public health and health care. Official opponent: Head of the Division of Medical and Social Researches of the Kulakov Scientific Centre of Obstetrics, Gynecology and Perinatology, Honored Scientist of the Russian Federation Ph.D. (Medicine) O.G. Frolova 126 REVIEW of the official opponent for the thesis for the scientific degree of Candidate of Medical Sciences of Sobolev V.A. "The scientific basis of screening examinations and health measures among children, living in ecologically unfavourable territories" , in specialities - 14.00.07 - "Hygiene" and 14.00.33 - "Public health and health care". Relevance of the thesis topic. In the Russian Federation in general and in specific regions of the country for the past 15 years, the health of children and adolescents has been characterized by a stable tendency towards increase of sickness rate, spreading of chronic pathology, reducing the number of healthy children. The reasons for this situation can be a number of factors including ecological. As it is known ecological factors form in average up to 25% of human pathology, and in some regions the percentage of environmentally-related diseases can be much higher. Modern methods of molecular biochemistry, immunology and others have been developed and used to reveal a casual role of environmental xenobiotics in various diseases of children. Now, however, such methods are only accessible to clinical institutions, Centres for Pediatric Ecopathology having proper standard of laboratory-diagnostic equipment and highly skilled physicians. In this regard, the scientific basis for the use of rational methods of screening, identification of risk groups and medico-ecological rehabilitation of children living in contaminated territories is very up-todate and important, and the subject of the thesis of V.A. Sobolev is topical. Scientific novelty of the study is that, on the base of the author’s study of the whole complex of factors affecting the health of children (of anthropogenic chemical contamination of environmental of various quality and quantity contamination of soil with worms, as well as social and endemic biogeochemical factors) V.A. Sobolev developed and carried out rational comprehensive screening examination of children living in ecologically unfavourable territories, with the use of vegetative resonance test both as an independent methods and in conjunction with traditional clinical methods. All this allowed the author to form groups of children at risk objectively and to offer a differentiated approach to their medical and environmental rehabilitation. The reliability and substantiation of the results and conclusions don’t cause any doubts due to the large volume of researches, integrated approach, using modern research methods and adequate statistical methods. Scientific and practical importance of the work. The author has identified the priority risk factors for health of the population in the towns of the Sverdlovsk region and in Novomoskovsk of the Tula region on the base of evaluation of sanitary-hygienic state of the environment. It was analyzed the prevalence and structure of child’s pathology in individual towns, children’s groups of risk were revealed, screening examinations of children with the use of 127 vegetative resonance test were carried out. All this allows reasonably and differentiatedly to carry out medical and environmental rehabilitation of children living in ecologically unfavourable areas. In connection with the foregoing, the results obtained by the author are of great theoretical and practical significance for health and ecology, as well as for practical medicine. The structure of the thesis. The thesis of Sobolev V.A. is written in a traditional style. The work is presented on 140 pages, consists of a list of abbreviations, introduction, the chapter with literature review, the chapter on materials and methods of investigation, the four chapters of own research findings, conclusions, list of literature and applications. The thesis is sufficiently illustrated by 27 tables and 20 pictures. The problems associated with the health of the Russian Federation children living in ecologically unfavourable areas are summarized in the introduction. The aim and objectives of the examination are formulated on the basis of this material. They convincingly demonstrate scientific novelty and practical significance of the thesis. The main provisions for the defense are clearly formulated, reflect the main results of the work. Publication and implementation of the results are very significant and important for the theory and practice of hygiene, human ecology, public health and health care. In the chapter "Literature Review" the author deeply and intelligently analyzes published data on the studied problem. This allowed Sobolev V.A. to define the purpose, objectives and methodological focus of his researches very logically and convincingly. The chapter is written professionally, competently, in a good literary style. In Chapter 2, "Materials and study Methods," the organization of the examination and methodology used in this work are summarized. The understanding by the author of the thesis many-sidedness of the problem and methodically integrated solutions of the task put by the author causes great satisfaction. Chapter 3 presents the results of sanitary-hygienic characteristics of the towns of the Sverdlovsk region and Novomoskovsk of the Tula region. The author was quite right choosing the criteria for examinated areas. He selected the presence of Class 1 and Class 2 anthropogenic unhealthy chemical substances in the environment. He took into consideration the active growth of children’s cancer sickness rate as well. The author has studied and analyzed manmade chemical contamination of air, water and soil by a complex of these substances in 17 towns of the Sverdlovsk region, the sources of this pollution were revealed, endemic geochemical characteristics of the studied areas were established. V.A. Sobolev also introduced the results of the assessment of epidemiological status of drinking water and soil, soil contamination by helmints. It was also studied the sanitary – hygienic condition of atmospheric air and drinking water in Novomoskovsk of the Tula region, which the author has chosen as a control town in relation to the towns of the Sverdlovsk region. Chapters 4 and 5 present the results of health examination of 3183 children in the towns of the Sverdlovsk region and 933 children of Novomoskovsk of the Tula region. The author has convincingly 128 shown that great manmade contamination in the towns of the Sverdlovsk region determines 2 times higher index of prevalence of almost all diseases of children (except for diseases of the musculoskeletal system and allergic diseases). Moreover in the Sverdlovsk region several diseases of different organs and systems had more than 50% of children, and in Novomoskovsk - 23%. The author showed that the specificity of the complex of man-made chemical pollutants in different towns causes certain types of children’s pathologies specific to the town. Thus, the leading diseases in Nizhniy Tagil are the diseases of the respiratory and nervous systems, in Krasnouralsk - respiratory and digestive system diseases, etc. For Novomoskovsk of the Tula region diseases of the nervous and musculoskeletal systems of children have a priority. On the base of such material the author comes to the practically important conclusion that the specific effects of factors of the environment must be taken into account when forming multidisciplinary teams of medical specialists for examination of children from areas of ecological trouble. The use of the vegetative resonance test showed that it is informative (in relation to the child's body hypersensitivity to heavy metals) for screening large contingents of children both as an independent method of prenosological diagnostics, and in combination with traditional clinical methods. Such data are very important and promising for the solution of the corresponding problems of preventive medicine. The organization of the complex screening examination of children allowed the author of the thesis to form five groups at risk and to develop an adequate strategy for their rehabilitation. The author also found that a percentage of risk groups of children in different towns vary substantially. It obviously again mainly proves the specific character of technical chemical pollutions of the environment of different towns. In Chapter 6 of the thesis the author presented a staged program of medical and ecological rehabilitation of children living in ecologically unfavourable areas. The basis of this program was the formation of risk groups of children for a differentiated approach to health and environmental rehabilitation. The author rightly distinguishes the basic principle of rehabilitation of children - the principle of succession: clinical examination - hospital – sanatorium dispensary. This approach allows us to recommend the most effective methods of rehabilitation of children. In the "Conclusion" the main results of the work are summarized "Conclusions" on the thesis (6 points are capacious, quite reasonable and reflect the main points of the work. "Bibliography" contains 135 sources (103 domestic and 32 foreign). The publications of the author fully reflected the scientific results of the thesis. 129 The abstract of the thesis fully reflects the content of the work. Summarizing the above-mentioned I believe that the scientific statements, conclusions and recommendations of this work demonstrated a high degree of justification, reliability and innovation, and the thesis of Sobolev V.A. is a complete independent scientific work on a topical theme, in which a number of scientific problems are formulated and solved. The totality of these problems is essential in studying the influence of environmental factors (especially anthropogenic chemicals substances) on the health of children living in ecologically disadvantaged areas, as well as in the field of the prevention of a number of diseases. However, some observations on the thesis should be made: 1) in the text there are some misprints, statistical and syntactic inaccuracies. 2) At the beginning of Chapter 5 there is some repetition of the material of chapter 4 on the prevalence and structure of morbidity of children, which to some extent is authorized by a great importance of these problems. These remarks are not of fundamental importance and can’t influence the high total appreciation of the work. During the study of the thesis the question occured: What is the reason that the sensitivity of vegetative resonance test, equal to 72.9% and spespecificity - 33,8%, are inversely related to each other? Conclusion. The thesis of Sobolev Vladimir Anatolyevich: "The scientific basis of screening examination and health measures among children living in ecologically unfavourable territories”, is a research-qualification work, it includes a new solution of the topical problem - the development of scientific-based differentiatied approach to selection of principles of rehabilitation of the child’s population of ecologically unfavourable territories on the base of studying the impact of environmental factors complex on children's health. Speaking about relevance, methodological level, scientific novelty and practical significance of the thesis it is original, timely, completed research work. The thesis meets the requirements of Higher Examination Board of the RF for master's theses, and the author (competitor) deserves the award of the scientific degree of Candidate of Medical Sciences in specialties: 14.00.07 - Hygiene, 14.00.33 - Public health and health care.

Relevance of the work. Children's health is one of the most sensitive indicators, which reflect changes in environmental quality. With increasing pollution level the number of children with environmentally dependent changes in health status increases in the population. According to government statistics, almost 60% of children have chronic diseases. Significant contribution of environmental factors to the development of various types of pathology of children makes it necessary to develop a system of medical and ecological rehabilitation of children living in ecologically disadvantaged areas. In this regard, the reviewed manuscript, dedicated to the issue of preserving the health of children living in environmentally unfavourable areas is scientifically relevant. Practical relevance is determined by rational approaches to organizing screening identification of children's pathology and adequate strategy of rehabilitation and prevention of ecologically related diseases of children. These approaches are presented in V.A. Sobolev’s work. Relationship with the plan of the branches of science and economy and science programs. The thesis work was done in the laboratory of evaluation and prediction of population health of the Sysin of Human Ecology and Environmental Hygiene Research Institute of RAMS, in accordance with the program of research, "Development of methodology for use of noninvasive methods to assess the relation of “The Environment - Health» № 066. The study was carried out in the framework of the All-Russian Public Movement "Children are the future of Russia." Funding for the program "Sanatorium rehabilitation of children from areas of ecological trouble, suffering from chronic diseases, 2000-2002" was provided at the expense of Federal ecological fund of the Russian Federation means, the regional public organization "Hematologists of the world to children." The novelty of the research results, the conclusions of the thesis. In the reviewed paper it was developed and for the first time tested in practice, a targeted program aimed at identifying children at high risk of the environmentally dependent diseases to carry out a complex of preventive and curative measures, in accordance with the risk group. 131 It was established that the prevalence of children’s pathology and its structure in some towns, indicate the specificity of the environment factors which create an "ecological portrait" of the child's health, inherent in a particular town, which may have diagnostic value in the formation of hypotheses about possible local factors responsible for the emergence of diseases in the area. Specificity of environmental factors influence should be considered in the formation of multidisciplinary teams of medical specialists to examine children from areas of ecological trouble. The conclusions are convincingly formulated and scientifically grounded on the base of the results of a large volume of own researches and analysis of statistical and literature data. They follow logically from the stated factual materials of the thesis and reflect the objectivity of the received scientific data. Their trustworthiness is defined by a sufficient volume of the studied material, correct discussion of the results, as well as using modern methods of the research, using statistical, mathematical methods using computer program. Significance of the results obtained by the author for science and practice. The obtained results are recommended for use in the practice of public health authorities in order to improve health of children from areas of ecological trouble, to evaluate sanitary-hygienic state and social conditions of environment where children live on the basis of the high prevalence of certain diseases, as well as to help public health to hold consultation and examination of children in residence. Informativeness of noninvasive bio-resonance diagnostic method allows to carry out screening at the optimal time and thus significantly reduce the time and financial cost both for the detection of early prenosological states and for confirmation of the chronicity of pathological processes of the examined children. The results of the examination are used: 1) during the development of subprogram “Medico-ecological rehabilitation of the population" within the framework of the program "Environmental Protection of the Tula region in 2001-2005"; 2) during the implementation of a comprehensive assessment of the impact of human economic activity on the environment and its after-effects on health; this implementation was done by Interregional territorial management of technological and ecological supervision of the Federal Service for Environmental and Nuclear Supervision of the Central Federal District. Federal Research Centre of Pediatric Hematology, Oncology and Immunology of Russia Public Health uses the methods of organization and conducting of screening examinations and recreational activities developed in the thesis to identify ecopathology and to give specialized assistance to children living in ecologically unfavourable territories of the Russian Federation. The developed technique of organizing and conducting of recreational activities is implemented in several other regions (the Arkhangelsk, Moscow, Yaroslavl regions, Primorsky Krai, the Republics of Karelia and Khakassia) with the participation of the State Enterprise "International Children's Centre, which is one of the members of the federal target program "Development of All-Russian Children's Centres “Eaglet” and "Ocean". 132 The proceedings of the thesis of Sobolev V.A. are widely reflected in the scientific literature, including reviewed journals; they were presented at the scientific - practical conferences, including international ones. Assessment of the thesis. The thesis consists of introduction, literature review, the chapter devoted to the description of the scope and methods of the research, six chapters of their own researches, discussion of the findings, conclusions, list of reviewed literature and applications. The material is clearly structured and presented in a good scientific language. The text is found on 141 pages of a typewritten text. A degree of validity of scientific statements and conclusions. The work is performed on big actual material - over 4000 of children were examined. The results are statistically processed. Methodological level of the thesis meets modern requirements. As a result of the examination all the tasks set by the author have been resolved. Key provisions of the thesis are well argued, the findings correspond to the goals and objectives. The results obtained in the study are described in 6 publications. All of the above allows to draw the conclusion of evidence and validity of the scientific statements and conclusions in the thesis. The recommendations for the use of the results and conclusions of the thesis. Practical design can be used during conducting of screening examinations of children in environmentally disadvantaged areas, taking into account the peculiarities of environmental pollution, which form the specific structure of child’s morbidity and determine the severity of pathology. Rational approach to organizing of a screening identification of child’s pathology in view of ecological problems of areas is the definition of risk groups together with the development of adequate strategy for their bringing into a healthy state. The method of bio-resonance diagnostics (VRT) is recommended to determine the extent of the toxic burden on the organism during the examination of large groups of children from ecologically unfavourable areas. Abstract of the thesis corresponds to the content. As the comments it should be noted that not all data listed in the review of the literature are relevant to the research, in particular, issues of regulatory legal ensuring of the development of targeted national and regional programs of prevention and rehabilitation of children with environmentally-dependent pathology as the implementation of child’s rights to health care. It was also necessary to indicate the grouping of diseases according to ICD-10 in the tables describing morbidity of the examined contingents. These comments are not of fundamental nature and do not reduce the high scientific and practical significance of the researches. CONCLUSION The thesis of Sobolev Vladimir Anatolyevich "The scientific basis of screening examinations and curative measures among children living in ecologically unfavorable territories" is a complete scientific and 133 skilled work related to the actual problem in the field of hygiene and public health and health care. The work is fully meets the requirements of item 8 of the “Regulations on the procedure for conferring academic degrees "Higher examination board of the Russian Federation made on candidate theses, and the author deserves the award the scientific degree of Candidate of Medical Sciences in specialities 14.00.07 - Hygiene, and 14.00.33 - Public health and health care.
