Growth is… Increase of cell number, cell size, and intercellular space over the time Growth Assessment HEIGHT/LENGTH, WEIGHT, OFC IMPORTANT PARAMETERS OF GROWTH • Weight for Height or Length • BMI • Upper segment : Lower segment Ratio • Height Velocity • Mid Parental Height Range • Bone Age Growth charts COMMONLY USED WHO GROWTH CHARTS • Weight for age chart (Birth to 5 years) • Length for age chart (Birth to 2 years) • Height for age chart (2 to 5 years) • Weight for length/Height chart (Birth to 5 years) • Head circumference for Age chart (Birth to 3 years) • Body mass index for Age chart (2 to 20 years) Factors affecting Growth BIOLOGICAL FACTORS ENVIRONMENTAL FACTORS • Genetic potential • Socio-economic background • Nutrition • Parental education and parenting abilities • Endocrine factors : GH, Thyroxin, Insulin, Sex hormones • Fetal Health • Chronic Disease/ Syndromes • Emotional support for child • Adverse environmental and natural disasters (eg; famines) Low • Poor growth Nutrition Nutrition Excessive • Over growth Nutrition High • Poor growth Demand Growth Growth Related Disorders Primary weight related disorders Under weight Under weight with wasting Under weight with stunting Under weight with wasting and stunting Over weight Primary stature related disorders Short stature Proportionate Disproportionate Tall stature Proportionate Disproportionate Malnutrition Overweight, Obesity & Diet related noncommunicable disease Under weight Micronutrient related malnutrition Under Nutrition Stunting Wasting MAM SAM Micronutrient Deficiencies Micronutrient Excess Moderate Acute Malnutrition (MAM) When to suspect ? Moderate Acute Malnutrition Cont. Diagnosis • Mid Upper Arm Circumference (MUAC) 115 to 124 mm, or • Weight-for-height Z-score (WHZ) -2 to -3, and • No bilateral pitting edema MAM Associated Risk Progression to Severe Acute Malnutrition Faltering growth Cognitive deficits Acquired immunodeficiency Management In-patient Care Community Based Community-Based management of MAM • Supplementary feeding ◦ Ready-to-use therapeutic food (RUTF) ◦ Ready-to-use supplementary food (RUSF) ◦ Fortified flours • Preventive care Community-Based Preventive Care • Recognition of at-risk populations o Diarrheal illness o HIV • Supplementation strategies for prevention of malnutrition •Nutrition Counselling and Education Severe acute Malnutrition (SAM) Major problem in many low and middle income countries. Due to severe protein-calorie malnutrition. Contributes to about 1/3 of childhood deathsworldwide. Definition of SAM • Weight-for-height <-3 z-score of the child growth standards median • MUAC less than 115 mm in children, 6 months to 5 years old • +/- Bilateral oedema Complications of SAM Loss of appetite & Hypoglycaemia (<54mg/dl) Hypothermia (<35.5°C body temp. / <35°C under arm temp.) LRTI Severe pallor High fever Severe dehydration Not alert Convulsion SAM at Health Care WITH COMPLICATION WITHOUT COMPLICATION • Admit to hospital for inpatient treatment • Follow up in a clinic or health post every week or fortnightly • Take home ration of RUTF • Ensure that they receive other services (Deworming, Vitamin A, Immunization, etc…) Identify SAM in the Community When children between 0 to 59 months are brought to the clinic or health post OR Door to Door visits by Pubic Health Staff Measure Height/length Measure Weight Check for Oedema Identify SAM in the community Contd. Bilateral pitting oedema Refer to a PEDIATRITION Weight-for-height <3SD Management of SAM GENERAL PRINCIPLES FOR ROUTINE CARE (the ‘10 Steps’) 1. Treat/prevent Hypoglycaemia 2. Treat/prevent Hypothermia 3. Treat/prevent Dehydration 4. Correct Electrolyte imbalance 5. Treat/prevent Infection 6. Correct Micronutrient deficiencies 7. Start cautious Feeding 8. Achieve Catch-up growth 9. Provide Sensory stimulation and Emotional support 10. Prepare for Follow-up after recovery GENERAL PRINCIPLES … Cont. These steps are accomplished in 02 phase 1. Stabilization phase (2-7 days) 2. Rehabilitation phase (several weeks) I 1 Step 01:Treat /prevent Hypoglycaemia Treatment- ASYMPTOMATIC SYMPTOMATIC / <1.5MG/DL • Feed of F-75* OR Give 50ml bolus of 10% glucose orally • Recheck in 30 minutes • If not corrected, repeat above • IV 10% dextrose 5ml/kg followed by 50ml of 10% glucose by NG tube • Start feed F-75 after 30minutes & continue it every 1/2hourly for 2 hours • Monitor RBS after 2 hours • If blood glucose >3mmol/L, feed F-75 2 hourly • If blood glucose <3mmol/L, repeat F-75 every ½ hourly & start antibiotics *(F-75; milk base formula that contain 75kCal/100ml & 0.9g protein /100ml) Step 02:Treat /prevent Hypothermia TreatmentKangaroo care & wrap both with blankets Clothed and wrap the child, if mother is absent Monitor temperature 2 hourly to prevent hyperthermia during re-warming PreventionMonitor temperature 3 hourly Kangaroo care Avoid exposure to cold Step 03:Treat/Prevent Dehydration Hypovolaemia co exist with oedema Difficult to estimate dehydration status in severely malnourished children Do not use iv route for rehydration except in case of shock & then do with care. Infusion slowly to avoid overload to heart. Standard oral rehydration solution contain too much sodium and too little potassium for severely malnourished children. Therefore give special Rehydration Solution for Malnutrition(ReSoMal) Step 03:Treat/Prevent Dehydration contd. Treatment• ReSoMal 5ml/kg ever 30 minutes for 2 hours 5-10ml/kg/hour for next 4-10 hours (doses at 4,6,8,10 hours) • Monitor progress of rehydration ½ hourly for 2hours,then hourly for next 6-12 hours • If signs of fluid overload occur, stop fluids immediately and reassess after one hour. Step 4:Correct Electrolyte Imbalance Mainly K and Mg Treatment• Combined electrolyte/mineral solution Prevention• When rehydrating, give low sodium rehydration fluid (Eg: ReSoMal) • Prepare food without salt NOTE:- Oedema is partly due to electrolyte imbalance. So Do NOT treat with diuretics Step 05:Treat /Prevent infections Management• Measles vaccine if child is > 6m and not immunized (delay if the child is in shock) • If no complications If complications present Give Amoxicillin oral 15mg/kg 8 hourly for 5 days Gentamycin IV or IM 7.5 mg/kg once daily for 7 days + Ampicillin IV or IM 50mg/kg every 6 hors for 2 days Followed by Amoxicillin Oral 15mg/kg every 8 hourly for 5days If child fails to improve within 48 hours ADD: Cefotaxime NOTE- If the child is not passing urine, gentamicin may accumulate in the body and cause deafness. Do not give the second dose until the child is passing urine Step 6. Correct Micronutrient Deficiencies Anemia, vitamin and mineral deficiencies. Treatment• Multivitamin supplement • Folic acid 1 mg/d (give 5 mg on Day 1) • Zinc 2 mg/kg/d • Copper 0.3 mg/kg/d • Iron 3 mg/kg/d - but only when after start of gaining weight(DO NOT give iron initially as it can make infections worse) Step 7. Start Cautious Feeding Feeding should start immediately to prevent death. Management• Give F-75 formula 2hourly (or breast feeding + F-75) • Keep a 24-hour intake chart • Weigh daily and plot weight Target100 kcal/kg/d 1-1.5 g protein/kg/d 130 ml/kg/d of fluid (100 ml/kg/d if the child has severe oedema) Step 8. Achieve Catch-up Growth In the rehabilitation weight gain of >10 g gain/kg/d Management• Replace starter F-75 with the same amount of catch-up formula F-100 for 48 hours & then Increase the amount subsequently • Frequent feeds (at least 4-hourly) of unlimited amounts of a catchup formula • If the child is breastfed, encourage to continue with formula feeds (Note: breast milk does not have sufficient energy and protein) Target150-220 kcal/kg/d 4-6 g protein/kg/d Step 9. Provide Sensory stimulation and Emotional support Care, play and stimulation • A cheerful, stimulating environment • Structured play therapy 15-30 min/d • Physical activity as soon as the child is well enough • Maternal involvement when possible (e.g. comforting, feeding, bathing, play) Step 10. Prepare for follow-up after recovery • Closest outpatient care facility from week 1 • Give the mother a weekly ration of RUTF Advise parent or carer to: • Bring child back for regular follow-up checks • Ensure booster immunizations are given • Ensure vitamin A is given every six months Clinical variants of Severe Malnourishment Marasmus Kwashiorkor Marasmic kwashiorkor Marasmus Malnutrition without oedema “Wasting” Due to inadequate intake of all nutrients, but specially dietary energy sources Causes depletion of body fat stores & wasting of muscle mass An ADAPTIVE state Marasmus cont. Typically seen in infants, who are breast fed when the amount of milk is markedly reduced or In those who are artificially fed Earliest manifestation is ‘failure to thrive’ Associated with irritability or apathy Marasmus Clinical Features • Thin and wasted appearance with emaciated arms, thighs and buttocks • Head appears large relatively to the body with staring eyes • Stunting • Thin and dry skin • Thin, sparse hair • Irritable and fretful affect Kwashiorkor Oedematous malnutrition Due to very low intake of proteins “Sickness the baby gets when the new baby comes” Marked muscle atrophy with normal or increased body fat (fat maldistribution -> fatty liver) MALADAPTIVE state Kwashiorkor cont. Characterized by symmetrical peripheral pitting oedema in dependent regions and proceed cranially Profoundly low levels of albumin leads to oedema in these children ◦ Mild – Odema involving feet ◦ Moderate – feet,legs +/- Upper limbs ◦ Severe – generalized oedema or moderate + facial odema Kwashiorkor Clinical features Variable weight for age Moon face with or without facial oedema Oedematous extremities Distended abdomen/ pot belly Hepatomegaly (fatty liver) Marked muscle atrophy Apathetic, listless behaviour Kwashiorkor Clinical features cont. Skin Manifestations Flaky paint dermatosis Hair depigmentation Flag sign (due to intermittent adequate dietary intake) Dry, brittle, thin, lusterless hair Fissured or ridged nails Short Stature A height below – 2SD for the age and the sex of the child Causes for Short Stature Familial – within MPHR, normal development, normal onset of puberty. Constitutional delay on growth – short in childhood, delayed puberty, final height normal, FHx Small for gestational age Chromosomal – Down, Turner, Noonan, Russell- Silver Nutritional – insufficient food, restricted diets, poor appetite long term illness – Coeliac disease, Crohn’s disease, CKD Psychological – physical and emotional deprivation Endocrine – Hypothyroidism, GH deficiency, Cushing syndrome Evaluating of Short Stature Short stature Detailed history, examination History and Examination HISTORY EXAMINATION • Birth weight • Growth parameters • When was detected • Upper segment to lower segment proportion • Any significant chronic illness • Dysmorphism • Detailed diet history • Features of endocrine/ nutritional disorders • Long term drugs • Features of chronic illness • Family history of short stature. • Development milestones Short stature Detailed history, examination Abnormal Syndromic Non syndromic Normal BA=CA Within MPHR BA < CA Below MPHR Bone Age Skeletal maturity Normally chronical and bone age should be the same Otherwise health child difference less than 2 years can be normal Mid parental height Male = father’s ht + mother’s ht + 12.5cm Female = father’s ht + mother’s ht − 12.5cm MPHR = MPH +/- 8.5cm Syndromes/ Chromosomal disorder Down syndrome Turner syndrome Noonan syndrome Russell- silver syndrome Short stature Detailed history, examination Abnormal Syndromic Normal Non syndromic Proportionate BA < CA Under nutrition Chronic disease Drugs Disproportionate Endocrine BA=CA BA < CA Within MPHR Below MPHR Familial Short Stature Constitutional Short Stature Short upper segment Short lower segment Thoracic dystrophies/Scoliosis Achondroplasia,osteogenesis imperfecta, rickets Investigations Tall Stature Height for age and sex above +2SD Causes for Tall Stature Familial – most common Obesity – puberty is advanced so final height centile is less Secondary – hyperthyroidism, excess sex steroids, excess adrenal androgen steroids, excess growth hormone secretion Syndromes – Marfan, Homocystinuria, Klinefelter Xn, Sotos Xn Excessive growth at birth – maternal diabetes, primary hyperinsulinism, Beckwith Xn Tall Stature Detailed History & Examination Syndromic Proportionate Non-syndromic Disproportionate Beckwith – Wiedemann Xn Marfan Xn Weaver Xn Klinefelter Xn Sotos Xn BA = CA BA > CA Familial tall stature Non obese Normal Puberty Growth hormone excess Obese Advanced puberty Precocious puberty Exogenous obesity Summary MAM SAM Clinical presentation Incidental finding Parental concern MOH clinic With any complication of SAM Kwashiorkor Marasmus Diagnosis MUAC – 115-124mm OR Weight/Height -2SD to -3SD MUAC less than 115cm Weight/Height <3SD Management Mainly Community Based Supplementation & preventive measures Under Paediatrition 10 steps Complications Progression to SAM Faltering growth Cognitive deficits Acquired immunodeficiency Loss of appetite, hypoglycemia Hypothermia LRTI, High Fever Severe pallor & dehydration Not alert, convulsions Summary Marasmus Kwashiorkor Malnutrition without Oedema Malnutrition with Oedema Inadequate Calorie Intake Inadequate Protein Intake Adaptive state Maladaptive state Low weight/height Variable weight/age References o Illustrated Textbook of Paediatrics o Concise Textbook of Pediatrics o Up to Date o Management of Severe Acute Malnutrition – Manual for Health Workers in Sri Lanka Q & A???
