insatiable hunger, hypotonia, short stature, hypogonadism, cognitive impairment, behavioral problems Angelman Syndrome: Maternal chromosome 15q deletion ("happy puppet syndrome"); severe mental retardation, no speech, ataxia, jerky movements, seizures Genetic Disorders: Beckwith-Wiedemann syndrome (Wilms tumor), retinoblastoma (RB1 gene), Li-Fraumeni syndrome (p53) Gene Regulation: Noncoding RNAs, RNA interference, imprinting, gene silencing MLH1: Role in inherited colon cancer; DNA repair failure Section 2: Immunology (Questions 21-72) HIV/AIDS: Helper T cells (CD4+), combination antiretroviral therapy, CNS reservoir DiGeorge Syndrome: T-cell deficiency, low calcium, tetany Complement System: Anaphylatoxins (C3a, C4a, C5a) Inflammatory Response: Nonspecific, vascular injury (redness, warmth, swelling, pain), systemic effects (fever, leukocytosis) Mast Cells: Activation by venoms and toxins Neutrophils: Predominant phagocytes in early inflammation Immunoglobulins: Classes (IgG, IgA, IgM, IgD, IgE); IgE = primary cause of allergies; IgA with J chain Hypersensitivity Reactions: Type I (allergic, IgE-mediated), Type III (Arthus reaction, immune complex), Type IV (cell-mediated) Alloimmune Disease: Graves disease, erythroblastosis fetalis Serum Sickness: Immune complex formation Infectious Disease: Bacteremia, endotoxins, viral evasion, antigenic variation, pathogenicity Section 3: Hematology (Questions 73-92) Hemolytic Disease of Newborn: Rh incompatibility, ABO incompatibility, phototherapy, phenobarbital Anemia: Iron deficiency (children, pallor with Hb 5 g/dL), hereditary spherocytosis (25% new mutations), aplastic crisis, G6PD deficiency (icterus neonatorum) Sickle Cell Disease: Autosomal recessive, triggers (hypoxemia, dehydration, increased osmolality) Coombs Test: Indirect = maternal antibodies Fetal vs. Adult Hemoglobin: Fetal = 2α + 2γ chains Section 4: Pulmonary System (Questions 93-153) Pulmonary Function Testing: Diagnostic and therapeutic roles; screening for abnormalities Restrictive Lung Disease: Fibrosis → decreased functional residual capacity Oxyhemoglobin Dissociation Curve: Right Shift = Acidosis, fever, hypercapnia, increased metabolism → easier O₂ release Left Shift = Alkalosis, hypothermia, hypocarbia → harder O₂ release Carbon Dioxide Transport: Primarily as bicarbonate Alveolar Physiology: Pores of Kohn, surfactant, alveolar radius, pulmonary vasoconstriction with hypoxia Gas Exchange: Ventilation, diffusion, perfusion; alveolar dead space Lung Volumes: Vital capacity (VC), functional residual capacity (FRC), residual volume (RV) Aging Lung: Increased compliance, decreased elastic recoil, increased residual volume Pathophysiology: Emphysema (increased compliance), asthma (inflammation → hyperresponsiveness), chronic bronchitis (mucus hypersecretion ≥3 months/year ×2 years), ARDS (pulmonary edema) Infections: Tuberculosis (air droplet), viral pneumonia (mild, self-limiting, can lead to secondary bacterial infection), hospital-acquired pneumonia (Pseudomonas aeruginosa) Pediatric: Laryngotracheobronchitis (croup, highest incidence fall/winter), stridor, peritonsillar abscess Section 5: Renal/Urinary System (Questions 154-225) Nephron Structure: Juxtamedullary (urine concentration), renal cortex, glomerulus, Bowman's space Glomerular Filtration: Net ultrafiltration pressure; decreased GFR with increased Bowman's hydrostatic pressure Tubular Functions: Reabsorption (water - passive), secretion (H⁺ and K⁺) Renin-Angiotensin-Aldosterone System: Aldosterone = Na⁺ and water reabsorption; renin = angiotensin activation Renal Blood Flow: mL/min Urinary Tract Obstruction: Hydronephrosis, decreased GFR Renal Calculi: Most common = calcium; struvite = magnesium, ammonium, phosphate Acute Glomerulonephritis: Poststreptococcal (Group A β-hemolytic strep), antigen-antibody complex, hematuria, proteinuria, edema, hypertension, tea-colored urine Nephrotic Syndrome: Proteinuria, hypoalbuminemia, hypercholesterolemia, frothy urine, periorbital edema UTI: E. coli (most common), fimbriae, biofilm, siderophores Congenital: Hypospadias/epispadias repair at 18 months; Potter syndrome (wide-set eyes, parrot beak nose, low-set ears, receding chin); renal dysplasia, horseshoe kidney Section 6: Cancer/Oncology (Questions 226-256) Malignant Tumors: Metastasis via vascular and lymphatic systems; sarcoma = connective tissue origin Tumor-Suppressor Genes: RB1, p53 (Li-Fraumeni syndrome); caretaker genes (DNA repair) Risk Factors: Tobacco (declining since 1997), alcohol (oral cavity, larynx, pharynx, liver), UV radiation (BCC, SCC), asbestos (lung), obesity (esophageal, kidney, colorectal) Melanoma: Fair skin, ≥3 sunburns, sudden appearance Childhood Cancers: Leukemia (most common), CNS tumors (most common solid tumor), embryonic tumors (undifferentiated), 80% cure rate Viral Oncogenesis: Epstein-Barr virus, Hepatitis B & C, HPV Diagnosis: Catecholamines (adrenal tumors), staging (Stage 3 = regional spread) Cachexia: Early satiety, altered metabolism, sign of cancer Radiation Therapy: Kills cancer cells while sparing normal tissue 5.
