It consists of a study of specific disease processes as they affect particular organs and systems. This manual therefore aims to: 1. reinforce the concepts and facts about gross and microscopic changes in various diseases; 2. facilitate the understanding and retention of information regarding major features of important pathologic condition by means of drawings; 3. encourage understanding of diseases through ClinicoPathologic Correlation; 4. encourage supplementary reading through answers to questions at the end of each exercises. Each exercise starts with a general discussion of the diseases of the particular organ-system in consideration. This is followed by a short description of the specific disease for study and a short clinical protocol, where warranted. Spaces are provided for drawings of gross and/or microscopic features of the diseases included in the manual. Efforts have been exerted to include only diseases which are commonly encountered by a primary health care physician and those not so common but interesting conditions. Students are encouraged to think of the clinical manifestations which may arise from the morphologic findings found in the diseases and vice versa, that is, think of the possible pathologic findings giving rise to a patient’s clinical manifestations. Pages of the textbook where the diseases are discussed were likewise included to facilitate reading on the topic. The questions at the end of each disease serve to further increase knowledge and stress certain important points on the topic. Always include a landmark in your drawing to help you identify the organ of involvement. This manual serves as a guide in the laboratory and does not replace the textbook in any way. Requirements: Colored pencils - individual Robbins and Cotran Pathologic Basis of Disease by Kumar, Abbas, and Aster; 9th Edition – one per group Textbook of Histology by de Fiore – one per group M.A.E.

DISEASES OF THE HEART Slides: # 184 Myocardial Hemorrhage # 39 Subacute Bacterial Endocarditis DEMO Rheumatic Heart Disease Gross : Rheumatic Heart Disease Tetralogy of Fallot Subacute Bacterial Endocarditis Patent Ductus Arteriosus Introduction: Cardiovascular disease tops the cause of death in the world. The developing countries account for about 80% of the burden. In the Phillipines, the 2016 DOH statistics place Ischemic heart disease as the number cause of death causing 12.7% death but if Hypertensive diseases (5.3%) and other Heart diseases (4.5%) are included the total death rate goes up to 22.5%. The major categories of heart diseases include congenital heart, ischemic heart, hypertensive heart, valvular, and primary myocardial diseases. CONGENITAL HEART DISEASES Congenital heart disease refers to cardiovascular abnormalities that one is born with. Most of these disorders arise from errors in embryogenesis during the third to eight weeks of gestation, when major cardiovascular structures start to form and to function. Congenital heart diseases are mainly caused by sporadic genetic abnormalities such as single gene mutations, small chromosomal deletions, and monosomies and trisomies. The most common genetic cause of congenital heart disease is trisomy 21 (Down Syndrome) where 40% of the patients have one or more heart defects. Most affected patients have no identifiable genetic factors such that environmental factors, alone or in combination with genetic factors may also contribute to congenital heart disease. In some cases, environmental factors (toxin or infection) may be the primary cause, e.g., congenital rubella infection, gestational diabetes, and exposure to teratogens. Nutritional factors may also modify risk of congenital heart disease. The major categories of congenital heart disease include malformations causing: - left-to-right shunt (Atrial Septal Defect, Ventricular Septal Defect and Patent Ductus Arteriosus) - right-to-left shunt (Tetralogy of Fallot, Transposition of Great Arteries, and Tricuspid Atresia - obstruction (Coarctation of the aorta, pulmonary stenosis and atresia and Thisaortic material is downloaded for Timothy Sam M.

PATENT DUCTUS ARTERIOSUS: p 535 1.1 Definition: PDA is persistence after birth of the normal communication between the pulmonary arterial system and the aorta of the fetus. About 90% occurs as an isolated anomaly and 10% in association with VSD, coarctation of the aorta or pulmonary or aortic stenosis. PDA normally constricts and closed functionally 1 – 2 days after birth. 1.2 History: An intrauterine fetal death baby, 37 – 38 weeks, was delivered in the hospital. History revealed mother had viral infection during the first trimester of pregnancy. P.E. revealed a macerated fetus.

TETRALOGY OF FALLOT: p 535 2.1 TOF represents the most common cyanotic congenital heart disease. The four cardinal features of TOF are ventricular septal defect, subpulmonic stenosis, overriding of the aorta, and hypertrophy of the right ventricle. The clinical consequences of TOF depend primarily on the severity of subpulmonic stenosis. 2.2 History: A 2 year old child was admitted because of difficulty of breathing and cyanosis.

The valves should be mobile, pliable and with structural integrity. The aortic and pulmonic valve should open during systole to allow blood to go to the aorta and systemic circulation and the lungs for gas exchange, respectively. While the mitral and tricuspid valve should close during systole to prevent backflow of blood to the left and right atrium, respectively. The functional disturbances produced by valvular disease are stenosis and insufficiency. Stenosis leads to failure of a valve to open completely, thus impeding forward flow. Insufficiency or regurgitation, on the other hand, is the failure of a valve to close completely, thus allowing backward flow. 4. RHEUMATIC HEART DISEASE: p 557 4.1 Definition: RHD is the long-term result of active rheumatic carditis presenting clinically as valvular heart disease 4.2 Etiology: Recurrent rheumatic fever caused by β-hemolytic streptococcus.

SUBACUTE INFECTIVE ENDOCARDITIS (SBE): p 559 5.1 Definition and Etiology: One of the most serious of all infections is characterized by colonization or invasion of heart valves, mural endocardium, or other cardiovascular sites by a microbiologic agent, leading to the formation of bulky, friable vegetations composed of thrombotic debris and organisms often associated with destruction of the underlying cardiac tissues. Infective endocarditis is classified into acute and subacute forms. Acute endocarditis is characterized by destructive, tumultuous infection, frequently of a previously normal heart valve by a highly pathogenic organism, like S. aureus, leading to death within days to weeks of more than 50% of patients despite antibiotics and surgery. SBE is caused by low virulent organisms, like S. viridans, in a previously abnormal heart especially on deformed valves, appear insidiously, pursue a protracted course for weeks to months, and patients recover after appropriate antibiotic treatment. 5.2 History: A 25 years old, known RHD patient was admitted because of fever, easy fatigability, loss of weight, and flu-like symptoms.

DISEASES OF THE LUNGS Slides: # 46 # 100 # 101 # 48 DEMO Atelectasis Bronchopneumonia Lobar pneumonia Abscess, lungs Bronchiectasis Gross : Bronchiectasis Bronchogenic carcinoma Introduction: The cardinal function of the lung is to facilitate gas exchange between blood and inspired air. The respiratory system arises as an outgrowth from the ventral wall of the foregut. From the trachea, the left and right main stem bronchi arise. The bronchi further divides into bronchioles leading to the terminal bronchioles and the acinus. An acinus is made up of respiratory bronchiole, alveolar ducts and alveolar sacs. Microscopically, the entire respiratory tree is lined by pseudostratified columnar epithelium, except for the vocal cords which are lined by squamous epithelium. 1. ATELECTASIS p 670 1.1 Definition: incomplete expansion (neonatal atelectasis) or collapsed of a previously inflated lung leading to an “airless” parenchyma Forms A. Resorption atelectasis Etiology complete airway obstruction with resorption of air in dependent areas causing collapse and shift of mediastinum towards atelectatic lung B.

DISEASES OF THE LIVER AND THE BILIARY SYSTEM Slides on: # 111 # 159 # 174 # 212 # 107 # 151 CPC, liver Post-necrotic cirrhosis ( plus gross ) Parasitic cirrhosis Tuberculosis, liver Cholangiocarcinoma Chronic cholecystitis Introduction: The normal adult liver weighs 1,400 to 1,600 gm. It is supplied by the portal vein (60 – 70%) and the hepatic artery (30 – 40%). The liver has been divided into metabolic lobules (hexagonal) or acini. The acini are triangular areas with apices at the terminal hepatic venules or central veins and bases at the portal tracts. The acinus is further subdivided into zones 1, 2, and 3. Zone 3 is located around the central vein whereas zone 1 is around the portal triad. Many forms of hepatic injury exhibit a zonal distribution. Review the histology of the liver. See the relative locations of the hepatocytes, sinusoids, bile canaliculi, Kupffer cells, Ito cells, limiting plates, and portal triads. 1. CHRONIC PASSIVE CONGESTION, LIVER: p 864 Definition: Accumulation of blood in the vascular system due to obstruction to flow. Etiology: Acute and chronic passive congestion of the liver usually reflects acute or slowly developing cardiac decompensation, most commonly right – sided heart failure. But because there is an element of preterminal circulatory failure in every death, congestive hepatic changes are commonplace at autopsy. History – A 76 year old male was admitted because of dyspnea, wheezing and a a grade 3 pitting pedal edema. He is a 50-pack year cigarette smoker, barrel-chested and breaths through pursed lips. He died one month after admission because of right-sided heart failure. An autopsy was done which showed a right ventricular hypertrophy and hepatomegaly.

DISEASES OF THE ENDOCRINE SYSTEM AND EXOCRINE PANCREAS Slides: # 054 # 056 # 130 # 146 # 125 # 175 # 40 Hurthle cell adenoma Follicular adenoma Hashimoto’s thyroiditis Papillary carcinoma, thyroid Parathyroid adenoma Adrenal hemorrhage Acute hemorrhagic pancreatitis DISEASES OF THE THYROID GLAND Introduction: The thyroid gland is one of the most responsive organs in the body. Free T3 and T4 act through specific nuclear receptors to modulate cell growth and functional activity of all kinds. The gland responds to many stimuli and is in constant state of adaptation. Diseases of the thyroid are of great importance because most are amenable to medical or surgical management. They present principally as thyrotoxicosis (hyperthyroidism), hypothyroidism, and as a focal or diffuse enlargement of the gland (goiter). 1. HURTHLE CELL ADENOMA: pp. 1093-1094 Adenomas of the thyroid are typically discrete, solitary masses derived from follicular epithelium, and hence are also known as follicular adenomas. In general, follicular adenomas are not forerunner to carcinomas but share genetic alterations. Hurthle cell adenomas are composed of follicular cells with abundant granular, eosinophilic cytoplasm, are well-encapsulated, and have a distinct growth pattern from the adjacent non-neoplastic thyroid tissues. History – A 36 year old female from was admitted because of an rightsided anterior neck mass of 1 year duration. On radionuclide scanning, the mass took up less radioactive iodine than the normal thyroid parenchyma (cold nodules). A subtotal thyroidectomy was performed and specimen submitted for histopathologic examination. This material is downloaded for Timothy Sam M.

FOLLICULAR ADENOMA: pp. 1093-1094 Adenomas of the thyroid are typically discrete, solitary masses derived from follicular epithelium, and hence are also known as follicular adenomas. The vast majority of adenomas are nonfunctional although a small proportion produces thyroid hormones which is independent of TSH stimulation (thyroid autonomy) and causes clinically apparent thyrotoxicosis. .

HASHIMOTO’S THYROIDITIS : pp. 1086-1088 Also referred to as struma lymphomatosa, is marked by intense infiltrate of lymphocytes admixed with plasma cells that virtually replace the thyroid parenchyma. It is the most common cause of hypothyroidism in regions that have sufficient iodine and a major cause of nonendemic goiter in children. Hashimoto’s thyroiditis is an organ-specific, autoimmune disease caused primarily by a defect in T-cells. B cells from thyroid tissues of patient with Hashimoto’s disease are activated and secrete autoantibodies directed against thyroid antigens (TSH receptor, iodine transporter, thyroglobulin, and thyroid peroxidase). History- A 50 year old woman was admitted because of an anterior neck mass of 3 months duration associated with lethargy easy fatigability, and cold intolerance. Patient also noticed slow mental process and speech. Pertinent P.E. findings: T=37.2oC, HR= 60/min; BP=90/60 mm Hg; mass at the anterior neck measuring 4x3 cm.; firm, movable, well-delineated borders, and moves with deglutition. Grade II nonpitting pedal edema; TSH=increased, T3 and T4 = decreased. A subtotal thyroidectomy was performed and specimen submitted for histopathological examination. Biopsy revealed normal thyroid follicles with colloid, dense lymphocytic infiltrates, atrophic thyroid follicles, lymphoid follicles with germinal center formation, and Hurthle cells.

PAPILLARY CARCINOMA, THYROID : pp. 1094-1097 Papillary Carcinoma is the most common morphologic variant of thyroid carcinoma (85%). Irradiation of the head and neck area during the first two decades of life is particularly carcinogenic to the thyroid. Some variants are associated with activation of Papillary thyroid carcinoma (PTC) oncogene in combination with RET proto-oncogene in chromosome 10 (RET/PRC). History: A 24 year old female sought admission because of an anterior neck mass of two years duration not relieved by medications. Patient is generally well. Laboratory examinations were with in normal limits. The only significant finding is the presence of a “cold” nodule within the thyroid. A fine needle aspiration biopsy of the nodule revealed “negative for malignant cells” so a subtotal thyroidectomy with frozen section biopsy was contemplated which was released as “malignant”. A total thyroidectomy was performed. Morphology: normal thyroid follicles, the tree-branching pattern, “Orphan Annie eyes” appearance of nuclei, nuclear grooving, and pseudoinclusions.

It consists mostly of chief cells which are polygonal cells that contain the parathormone. The activity of the pathyroid gland is controlled by the level of ionized (free) calcium in the blood. Decreased level of free calcium stimulate the synthesis and secretion of PTH and increased free calcium level serves as a negative feed-back loop to PTH secretion. 1. PARATHYROID ADENOMA pp. 1101-1103 Parathyroid adenoma causes 85-95% of primary hyperparathyroidism which leads to hypercalcemia . Other causes include Primary hyperplasia, 5-10%, and Parathyroid carcinoma less 1%. The adenomas are almost always solitary, weighs from 0.5 to 5gm., soft, tan, well-circumscribed and covered by a delicate capsule.

The normal gland weighs about 4 gm but may be decreased with acute stress due to lipid depletion and increased due to hypertrophy and hyperplasia in chronic stress. The adrenal cortex secretes glucocorticoids, mainly cortisol (zona fasciculata); mineralocorticoids, most important is aldosterone (zona glomerulosa); and sex steroids (zona reticularis). The adrenal medulla synthesizes and secretes catecholamines (mainly epinephrine). 1. ADRENAL HEMORRHAGE Massive adrenal hemorrhage may destroy sufficient adrenal cortex to cause acute adrenocortical insufficiency. This may occur among newborns following a prolonged and difficult delivery, in patients maintained on anticoagulant therapy, postsurgical patients who developed DIC and as a complication of bacteria (Waterhouse-Friderichsen Syndrome). History – A 2 year old child was admitted because of high grade fever, vomiting , and delirium.

The exocrine pancreas consists of 80-85% of the organ and is composed of acinar cells that secretes variety of proenzymes such as trypsinogen, chymotrypsinogen, procarboxypeptidase, proelastase, kallikreinogen and prophospholipase A & B. 1. ACUTE HEMORRAHGIC PANCREATITIS pp 884-887 Acute pancreatitis is a relatively common disorder characterized by acute onset of abdominal pain due to enzymatic necrosis and inflammation of the pancreas. About 80% of the disease is associated with biliary tract disease and alcoholism. History: A 45 years old, male, chronic alcoholics was brought to the emergency room because of severe abdominal pain of one hour duration. He had just had a drinking spree in a friend’s birthday party and had barely slept when he was awakened by severe abdominal pain and vomiting. Pertinent P.E. findings include BP = 80/50 mm Hg; T = 38.5 oC; HR = 115/min with cold, clammy perspiration. Emergency treatment was given but patient succumbed 16 hours after admission.

Biochemically it is defined by its special blend of organic (35%), cells and proteins matrix and inorganic (65%) elements, calcium hydroxyapatite. Joints are constructed to provide both mobility and mechanical support. Joints are of two types: solid joints (synarthroses) and cavitated (synovial) joints. Hyaline cartilage is present in the articular surfaces and serves as an elastic shock absorber and wear-resistant surface. 1. OSTEOSARCOMA: pp 1198 – 1200 Osteosarcoma is a malignant mesenchymal tumor in which the malignant cells produce bone matrix. It is the most common primary malignant tumor of the bone (20%), exclusive of myeloma and lymphoma. Bimodal age distribution is noted in osteosarcoma, 75% occurs in those less than 20 years old and smaller second peak in the elderly. Most common site is distal femur and proximal tibia (60%). History: A 24 year old male was admitted because of fracture sustained during a game of basketball. X-ray of the lower right leg showed fracture of the tibia in an area of lytic and blastic mass that has permeative margins. A surgery was performed with frozen section of the lesion.

DISEASES OF THE CENTRAL NERVOUS SYSTEM Slides : # 115 # 003 # 31 # 117 # 162 T.B. meningitis Viral encephalitis Malaria, brain Astrocytoma, brain Meningioma Introduction: The functional properties of the CNS are topographically localized so that diseases in the CNS are also geographically distributed. Thus their topographics serve to individualize them and to facilitate their recognition. Examples: Caudate nuclei Huntington’s disease Substantiate nigra Parkinsonism Motor neurons of spinal cord, brain Amyotrophic lateral sclerosis stem & cerebrum Anterior horn cells of the spinal cord Poliomyelitis and motor nuclei of brain stem Temporal lobe of cerebrum Herpes simplex Medulla Rabies Brain stem and cerebellum Gliomas (childhood) Cerebrum Gliomas (adult) The rate of evolution of the disease process and the age of the patient likewise give some clues as to the diagnosis and etiology of lesion. 1. TUBERCULOUS MENINGITIS: pp. 1274 Tuberculous meningitis may occur as a part of a systemic disease or as an isolated end-organ disease from a silent, usually pulmonary lesion. During hematogenous dissemination, T.B. bacilli may seed distant organ systems, including the meninges where the organism are destroyed in all organs but persist only in the meninges to cause tuberculous meningitis. The brain may also be involved to cause a diffuse meningoencephalitis. History: A 29 year old female was admitted because of severe frontal headache and vomiting of food previously taken of 2 days duration. This started as body malaise, anorexia, and low grade fever of one week. Because of the increasing severity of the headache and persistence of vomiting, patient consulted and subsequently admitted. Pertinent P.E. findings include: T = 380C; BP = 120/80 mm Hg; HR = 88/min; (+) neck rigidity; (+) Babinski and Brudzinski’s sign.

VIRAL ENCEPHALITIS: pp. 1275 -1278 Viral encephalitis or encephalomyelitis is a parenchymal infection of the brain almost invariably associated with meningeal inflammation. The degree of tropism exhibited by some viruses is particularly striking in the nervous system. Some viruses infect specific cell types; others are restricted to particular areas of the brain. Direct indication of viral infection is the presence of inclusion bodies and, most importantly the identification of the virus by ultrastructural, immunocytochemical and molecular methods. History: An 18 year old female was admitted because of convulsions few minutes prior to admission. The present illness started 4 weeks prior to admission as upper respiratory tract infection of one week duration followed by lethargy and body weakness.

ASTROCYTOMA: pp 1306 – 1309 Tumors of the glial cells (Gliomas) include astrocytomas, oligodendrogliomas, and ependymomas. Fibrillary astrocytomas accounts for 80% of adult primary brain tumors. It is usually found in the cerebral hemispheres but may occur in the cerebellum, brain stem, or spinal cord. The highest grade lesions are characterized by a mixture of firm, white areas and softer, yellow foci of necrosis as well as cystic change and hemorrhage (GLIOBLASTOMA). History: A 34 year old male was admitted because of recurrent, severe headache of 8 weeks duration initially relieved by mefenamic acid.

Profile picture and Full Name in different platforms (Zoom, Telegram, Moodle, Zimbra) ATTENDANCE Will be checked during lecture and laboratory sessions You will be marked LATE if you enter the chat room within 16-30 minutes of the scheduled start of classes. You will be marked ABSENT if you enter the chat room 30 minutes after the scheduled start of classes. If three absences are incurred, the re-admission slip needs to be secured from the Department Chairman. An accumulated more than three absences (>20% of the total number of subject hours), can be given a grade of “unauthorized widrawal”. This will likewise be reported to the Office of the Dean. LECTURE Lectures will be conducted using ZOOM. Instructional learning objectives per topic will be uploaded via Moodle. LABORATORY Images of the tissues will be provided by the subject coordinator one week prior to slide orientation. Each student will be assigned to prepare a report (etiology, pathogenesis, gross and microscopic appearance, clinical features). The report will be graded accordingly equivalent to one quiz. For lesions that were previously tackled, the presentation need not be repeated again. Activities during the laboratory: orientation of new slides, drawing and labeling of the various lesions and answering guide questions in your manual. The camera needs to be on as the Zoom classes are ongoing to show that the students are answering the manuals after the reporting is conducted. Manuals will be submitted at the end of the session. SMALL GROUP DISCUSSION SGD session will be conducted using ZOOM. Three clinicopathologic (CPC) cases will be discussed during the semester. The case protocol will be uploaded via Moodle Each case will be discussed for three weeks: o The first and third cases will be discussed in the following order: 1st week – Clinical discussion : During this session the student is This material is downloaded for Timothy Sam M. Valdez (20190107101) expected toNicanor know the following main clinical diagnosis, differential at FEU Dr. Reyes Medical: Foundation. diagnosis, other diseases that may be present, clinicalreserved. cause of death For personal use only. No other uses without permission. All rights 2nd week – Anatomic discussion : During this session, the student is expected to enumerate the anatomic diagnosis per organ and the basis. The diagnosis per organ will then be categorized as follows : o o o I : Disease causing death directly II: Disease/s contributing or related to death by cause or effect III: Significant disease/s not related to death but significant enough to contribute to the death of the patient IV: Incidental disease/s V: Anatomic cause of death 3rd week – correlation of clinical and anatomic findings. In the second case, the anatomic discussion will be conducted first before the clinical discussion (reverse CPC). Pretest will be given with MOODLE as platform The class will be divided into small groups with delegated faculty proctor. The students can volunteer to participate or the proctor may call the students randomly. The participation in the discussion will be graded accordingly. Correlation of Clinical and Anatomic Findings : A type written flow chart will be conceptualized showing the sequence of events based on the autopsy findings. The relationship of the autopsy findings with the clinical presentation is established. The pathophysiology needs to be explained. The ancillary procedures will also be discussed in correlation to the clinical and autopsy findings. This is an individual work and needs to be uploaded as an assignment using Moodle.

Laboratory questions will be in the form of “objective structured projection exam”. The fault tolerant system will be used. You are expected to be online 15 minutes prior to the start of examination. Manuals must be uploaded before the start of the long exam via Moodle . Late submission will have corresponding deductions. Coverage of long examinations will be uploaded via Moodle. Complete uniform (or white top with sleeves) must be worn. The laptop is the recommended gadget to use in taking the examination. Other gadgets that are opened which are caught on camera, or, images uploaded via telegram will be interpreted as an act of cheating. Academic dishonesty in any form, such as follows: attempt to cheat, assisting others to cheat or participating or engaging in such improper conduct is a serious violation. This will result in nullification of the student’s exam and administrative process will be initiated. Penalty for cheating/ attempt to cheat is dismissal from the medical foundation (FEU-NRMF revised student code of conduct 2015). Examples of improper conduct: looking at or copying from other student’s exam; using mechanical aid that is not permitted; allowing other student to copy your answer; communicating with another student during the exam; using unauthorized gadgets during the exam. Use Telegram for any questions and clarification and the proctor/IT will assist you. Make up of plating/s (excused) and long examination/s will be given within one week after submission of e-mail addressed to the department chairman, through the subject coordinator via Zimbra. Make-up examination may be in any format (essay, identification, matching, etc.). Answer key to examinations (short and long exam) will be made available via Moddle after all students have submitted. The key can be challenged within twenty-four (24) hours. Moodle count is final.
