Study Notes
Foundations of Pathology
- Pathology combines principles from chemistry, biochemistry, cell biology, anatomy, genetics, and physiology.
- General pathology includes topics such as cell injury, inflammation, immune disorders, thromboembolism, neoplasia, and infections.
- Clinical cases illustrate core principles of general pathology for better understanding.
Medical Specialty of Pathology
- Pathology involves examining patient specimens to diagnose diseases, including organs, tissue biopsies, blood, and other body fluids.
- Essential in prevention, diagnosis, treatment, and management of diseases.
Basic Competencies in Pathology
- Grasp core mechanisms of diseases: cell injury, inflammation, hemodynamics, immune disorders, neoplasia, genetics, and environmental factors.
Cell Injury and Responses
- Cellular injury occurs when stress exceeds a cell's adaptive capacity, potentially leading to cell death.
- Causes of cell injury: hypoxia, pathogens, immunologic dysfunction, inherited mutations, chemical exposure, physical trauma, and nutritional imbalances.
- Responses to injury include adaptations (hypertrophy, atrophy, hyperplasia, metaplasia), reversible injury, and irreversible injury leading to necrosis or apoptosis.
Inflammation and Repair
- Inflammation is a tissue reaction to injury, facilitating entry of immune cells and plasma proteins.
- Acute inflammation is an immediate response, involving vascular changes and neutrophils, while chronic inflammation is a prolonged response to persistent causes.
- Tissue repair starts during inflammation and involves coagulation, regeneration of cells, fibrosis, and remodeling.
Hemodynamic Disorders
- Tissue health relies on proper blood circulation for nutrient delivery and waste removal.
- Edema occurs when fluid balance is disrupted, while inadequate hemostasis can lead to hemorrhage and shock.
- Excessive clotting or embolism can result in ischemia or infarction.
Immune System Diseases
- Immunodeficiency diseases increase susceptibility to infections.
- Autoimmune disorders occur when the immune system mistakenly targets self-antigens.
Neoplasia
- Neoplasia involves unregulated tissue growth, which can be benign or malignant and arises from a single neoplastic cell.
Genetic and Environmental Diseases
- Genetic mutations can alter protein function, disrupt cellular homeostasis, and lead to disease.
- Environmental diseases stem from factors like climate change, drugs, physical injury, and nutritional imbalances.
Application of Pathology Knowledge
- Pathologists must apply their understanding of disease mechanisms to various organ systems and familiarize themselves with epidemiology, pathologic features, and diagnostic techniques.
- Knowledge of the clinical presentation and natural history of untreated diseases is crucial.
Diagnostic Methods in Pathology
- Pathologists perform gross and microscopic examinations, analyze laboratory tests, and oversee clinical laboratory functions.
- Two main areas: Clinical pathology (includes chemical analysis and microbiology) and Anatomic pathology (examines the structural effects of disease).
- Surgical pathology is prevalent in clinical practice, often focusing on neoplasms.
- Subspecialties include cytopathology, dermatopathology, hematopathology, and molecular genetic pathology.
Microscopic Examination Techniques
- Sampling methods include excision or biopsy, fine-needle aspiration, and cytologic smears (e.g., cervical Pap smears).
