Study Notes

Definition of Pathology

  • Study of disease, its causes, mechanisms, and effects.
  • Focuses on the structural and functional changes in cells, tissues, and organs.

Types of Pathology

  1. Anatomical Pathology

    • Examines tissues and organs to diagnose disease.
    • Includes surgical pathology (biopsies) and autopsy pathology.
  2. Clinical Pathology

    • Involves laboratory analysis of bodily fluids (blood, urine).
    • Assesses disease through chemical, microbiological, and hematological tests.
  3. Molecular Pathology

    • Studies diseases at the molecular level.
    • Utilizes techniques such as PCR, gene sequencing, and biomarkers.

Key Concepts

  • Etiology: Causes of disease, including genetic, infectious, environmental factors.
  • Pathogenesis: Development and progression of disease from initial stimulus to final outcome.
  • Morphological Changes: Structural alterations in cells and tissues, observed microscopically or macroscopically.

Disease Classification

  • Congenital: Present at birth (e.g., genetic disorders).
  • Acquired: Develops after birth due to various factors (e.g., infections, lifestyle).

Common Pathological Terms

  • Lesion: Abnormal change in tissue structure.
  • Inflammation: Body's response to injury or infection, characterized by redness, heat, swelling, and pain.
  • Necrosis: Premature death of cells or tissues due to injury or disease.
  • Apoptosis: Programmed cell death, a controlled mechanism.

Diagnostic Techniques

  • Biopsy: Removal of tissue for examination.
  • Imaging: Techniques like X-rays, CT scans, MRI to visualize changes.
  • Cytology: Study of cells for diagnosis, often using smears or aspirates.

Pathological Conditions

  • Tumors: Abnormal growths that can be benign or malignant (cancer).
  • Infectious Diseases: Caused by pathogens (bacteria, viruses, fungi, parasites).
  • Autoimmune Disorders: Immune system attacks the body's own cells.
  • Degenerative Diseases: Progressive loss of function or structure (e.g., Alzheimer's, osteoarthritis).

Role of Pathologists

  • Analyze samples to provide diagnostic information.
  • Collaborate with clinicians to guide treatment decisions and prognosis.
  • Conduct research to advance understanding of diseases and develop new therapies.

  • Infectious Diseases: Caused by pathogens like bacteria, viruses, fungi, and parasites.
  • Autoimmune Disorders: When the immune system attacks the body's own cells.
  • Degenerative Diseases: Progressive loss of function or structure, like Alzheimer's disease and osteoarthritis.

Role of Pathologists

  • Analyze samples to provide diagnostic information for clinicians.
  • Collaborate with clinicians to guide treatment decisions and prognosis.
  • Conduct research to advance understanding of diseases and develop new therapies.
