Study Notes
Systemic Pathology: Overview
- Systemic pathology examines diseases affecting specific organ systems.
- It involves understanding the structural and functional changes in tissues and organs due to disease.
- Emphasizes pathologic mechanisms behind disease, not just clinical manifestations.
Cardiovascular System
- Atherosclerosis: Characterized by plaque buildup in arteries. Risk factors include high cholesterol, hypertension, smoking, and diabetes. Leads to decreased blood flow, potentially causing ischemia and infarction. Microscopically, you see accumulation of lipids, smooth muscle cells, and fibrous tissue within the intima.
- Hypertension: Sustained elevation in blood pressure. Causes include various factors, e.g. renal disease, endocrine disorders. Can lead to various cardiovascular complications, including left ventricular hypertrophy.
- Coronary Artery Disease: Narrowing or blockage of coronary arteries, often due to atherosclerosis. Manifestation: Angina and Myocardial Infarction.
- Valvular Heart Disease: Structural defects in heart valves. Results in regurgitation or stenosis. Common causes: rheumatic fever, congenital heart defects.
- Cardiomyopathy: Disease of the heart muscle itself, resulting in impaired pumping ability. Can be hypertrophic, dilated, or restrictive.
Respiratory System
- Pneumonia: Inflammation of the lung tissue, often caused by bacterial, viral, or fungal infections. Clinical presentation: Fever, cough, dyspnea. Microscopically, you see inflammation within alveolar spaces.
- Asthma: Chronic inflammatory disorder of the airways. Characterized by bronchoconstriction, mucus production, and airway hyper-responsiveness.
- Lung Cancer: Aggressive malignancy, often associated with smoking. Classified broadly into small cell and non-small cell types. High mortality rate. Microscopically, diverse appearances based on specific subtypes.
- Pulmonary Embolism: Blood clot obstructing a pulmonary artery, reducing blood flow to lungs. Can lead to acute respiratory distress.
Gastrointestinal System
- Peptic Ulcer Disease: Erosion of the mucosal lining of the stomach or duodenum. Often related to Helicobacter pylori infection or nonsteroidal anti-inflammatory drug (NSAID) use.
- Gastritis: Inflammation of the stomach lining. Can be acute or chronic, associated with H. pylori infection or other factors.
- Crohn's Disease: Chronic inflammatory bowel disease affecting any part of the GI tract, transmural inflammation.
- Ulcerative Colitis: Chronic inflammatory bowel disease affecting primarily the colon. Mucosal inflammation, often limited to the colon.
- Liver Cirrhosis: Chronic liver disease resulting in scarring and fibrosis. Can be caused by various factors, including alcohol abuse, viral hepatitis, or nonalcoholic fatty liver disease (NAFLD).
- Pancreatic Cancer: Malignancy of the pancreas, often aggressive and with poor prognosis. Frequent presentation: painless jaundice. Can cause various gastrointestinal symptoms.
Renal System
- Glomerulonephritis: Inflammation of the glomeruli in the kidney. Can lead to kidney failure if untreated.
- Nephrotic Syndrome: Characterized by massive proteinuria, edema, and hypoalbuminemia. Glomerular damage is a key feature. Various causes possible.
- Acute Kidney Injury (AKI): Rapid decline in kidney function. Causes include prerenal, intrinsic, and postrenal factors.
Endocrine System
- Diabetes Mellitus: Characterized by hyperglycemia due to insulin deficiency or resistance. Type 1 and Type 2 are common forms.
- Thyroid Disorders: Disorders of the thyroid gland. Hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid), both with specific characteristic clinical and pathologic presentations.
Hematologic System
- Leukemia: Malignant disorder of blood cells, often involving abnormal proliferation of white blood cells. Various subtypes, each with distinctive clinical features.
- Lymphoma: Malignant disorder of lymphoid cells. Hodgkin and Non-Hodgkin lymphomas have different prognoses.
- Anemias: Group of disorders characterized by decreased red blood cell count or hemoglobin. Anemia can arise from various deficiency states (iron, B12, folate) or destruction of red blood cells.
Nervous System
- Multiple Sclerosis: Chronic inflammatory disorder affecting the central nervous system.
- Stroke: Disruption of blood flow to the brain, causing severe neurological deficits.
- Neurodegenerative Disorders: Progressive loss of neurons, exemplified by diseases like Alzheimer's disease, Parkinson's disease and Huntington's disease. Key features include accumulation of abnormal proteins in neurons.
Integumentary System
- Skin Cancer: Diverse types of skin cancers exist (basal cell, squamous cell, melanoma). Melanoma is the most significant type. Usually associated with excessive exposure to UV radiation.
- Psoriasis: Inflammatory skin disorder with characteristic red, scaly plaques.
Musculoskeletal System
- Osteoarthritis: Degenerative joint disease characterized by cartilage loss. Common causes include aging and overuse.
- Rheumatoid Arthritis: Autoimmune disease causing chronic inflammation in joints.
- Bone Fractures: Common injury and often a result of trauma or stress. The healing process involves various stages, including remodeling.
