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).
