BSc Nursing 2nd Year - Pathology: Important Topics (Exam Focus)

UNIT 1: GENERAL PATHOLOGY

1. Cell Injury, Adaptation & Death ⭐⭐⭐ (Most Important)

• Causes of cell injury (hypoxia, chemicals, infections, immune reactions)
• Reversible vs. irreversible cell injury - differences
• Types of cell death: Necrosis (coagulative, liquefactive, caseous, fat, fibrinoid) vs. Apoptosis - compare and contrast
• Cellular adaptations: Hypertrophy, Hyperplasia, Atrophy, Metaplasia, Dysplasia - definitions + examples
• Intracellular accumulations: fatty change (steatosis), glycogen, pigments (lipofuscin, melanin, hemosiderin)
• Pathological calcification: dystrophic vs. metastatic

• "Describe the types of necrosis with examples."
• "Differentiate apoptosis from necrosis."
• "Define and give examples of cellular adaptations."

2. Inflammation ⭐⭐⭐ (Most Important)

• Definition, cardinal signs (Calor, Rubor, Tumor, Dolor, Functio laesa)
• Acute inflammation: vascular changes, cellular events (margination, rolling, adhesion, emigration, phagocytosis)
• Chemical mediators: histamine, prostaglandins, leukotrienes, complement system, cytokines
• Types of exudate: serous, fibrinous, purulent (suppurative), haemorrhagic
• Morphological types of acute inflammation: serous, fibrinous, suppurative, ulcerative
• Chronic inflammation: causes, features, types (non-specific, granulomatous)
• Granuloma: definition, composition, causes (TB, sarcoidosis, leprosy)
• Differences between acute and chronic inflammation

• "Describe the vascular and cellular events of acute inflammation."
• "Write a short note on granulomatous inflammation."
• "List the chemical mediators of inflammation."

3. Repair and Wound Healing ⭐⭐

• Regeneration vs. repair
• Types of healing: primary intention (healing by first intention) vs. secondary intention
• Granulation tissue: composition and significance
• Factors affecting wound healing (local and systemic)
• Complications of wound healing

• "Describe the process of wound healing by primary intention."
• "What are the factors affecting wound healing?"

4. Hemodynamic Disorders ⭐⭐⭐

• Edema: pathogenesis (Starling forces), types - transudate vs. exudate
• Hyperemia and congestion (active vs. passive) - "nutmeg liver"
• Hemorrhage: types (petechiae, purpura, ecchymosis, hematoma)
• Thrombosis: Virchow's triad, types of thrombi, fate of thrombus
• Embolism: types - pulmonary embolism, fat embolism, air embolism, amniotic fluid embolism
• Infarction: red (hemorrhagic) vs. white (anemic) infarcts
• Shock: types (hypovolemic, cardiogenic, septic, neurogenic), stages, morphology

• "Write Virchow's triad for thrombosis."
• "Classify shock and describe its pathophysiology."
• "Differentiate transudate from exudate."

5. Neoplasia ⭐⭐⭐ (Most Important)

• Definition of neoplasm, benign vs. malignant tumor (differences in a table format)
• Nomenclature of tumors (carcinoma, sarcoma, adenoma, etc.)
• Carcinogenesis: chemical, radiation, viral (HPV, HBV, EBV)
• Tumor spread: direct extension, lymphatic, hematogenous, transcoelomic
• Paraneoplastic syndromes
• Tumor markers: PSA, AFP, CEA, CA-125
• Grading and staging of tumors (TNM staging)
• Host defense against tumors (tumor immunology basics)

• "Differentiate benign from malignant tumors."
• "Describe the routes of spread of malignant tumors."
• "Write a short note on carcinogenesis."
• "What are tumor markers? Give examples."

UNIT 2: SYSTEMIC PATHOLOGY

6. Diseases of Blood Vessels & Heart ⭐⭐

• Atherosclerosis: risk factors, pathogenesis (fatty streak - fibrous plaque - complicated lesion)
• Hypertension: benign vs. malignant, effects on target organs
• Ischemic heart disease: angina, MI (acute MI - zones, complications), sudden cardiac death
• Cardiac failure: left-sided vs. right-sided (effects on lungs and liver)
• Rheumatic fever and rheumatic heart disease

7. Respiratory System Pathology ⭐⭐

• Pneumonia: lobar, bronchopneumonia, interstitial - differences; causative organisms
• Tuberculosis (TB): primary vs. secondary TB, Ghon complex, types of lesions, caseous necrosis
• COPD: chronic bronchitis vs. emphysema (compare)
• Bronchial asthma: pathology
• Lung carcinoma: types (squamous cell, adenocarcinoma, small cell), risk factors

8. GIT Pathology ⭐⭐

• Peptic ulcer disease: gastric vs. duodenal ulcer - differences, complications
• Appendicitis: acute appendicitis pathology
• Liver diseases: hepatitis (viral - A, B, C), cirrhosis (causes, morphology, complications like portal hypertension)
• Jaundice: types - pre-hepatic, hepatic, post-hepatic (obstructive)
• Carcinoma stomach, carcinoma colon

9. Urinary System Pathology ⭐⭐

• Glomerulonephritis: nephritic vs. nephrotic syndrome
• Urinary tract infections (UTI)
• Renal calculi (nephrolithiasis): types, complications
• Renal failure: acute vs. chronic, causes
• Carcinoma kidney and bladder

10. Hematology (Diseases of Blood) ⭐⭐

• Anemia classification: microcytic, normocytic, macrocytic
• Iron deficiency anemia: causes, blood picture, treatment
• Pernicious anemia (B12 deficiency)
• Sickle cell anemia: pathogenesis, complications
• Leukemia: acute vs. chronic, lymphoid vs. myeloid - brief overview
• Lymphoma: Hodgkin vs. Non-Hodgkin - Reed-Sternberg cells

11. Endocrine & Other Systemic Topics ⭐

• Diabetes mellitus: Type 1 vs. Type 2, complications (macro- and microvascular)
• Thyroid disorders: goiter (simple, toxic), thyroiditis, carcinoma
• Diabetes insipidus vs. SIADH - briefly

12. Genetics (often included in 2nd Year) ⭐

• Chromosomal disorders: Down syndrome (Trisomy 21), Turner syndrome, Klinefelter syndrome
• Single gene (Mendelian) disorders: autosomal dominant (Huntington's, Marfan's) vs. autosomal recessive (PKU, CF, sickle cell)
• X-linked disorders: Haemophilia, Duchenne muscular dystrophy
• Multifactorial inheritance
