Study Notes
Introduction to Pathology
- Pathology is the study of disease, encompassing the structural, functional, and biochemical changes in cells, tissues, and organs.
- It analyzes the causes, mechanisms, and effects of diseases.
- Pathological processes affect all aspects of human health.
- Pathology is vital for diagnosis, prognosis, and treatment planning.
Types of Pathology
- Gross pathology: Examines tissues and organs using the naked eye, noting visible changes in size, shape, color, and texture. This often involves viewing organs, tissues, or lesions.
- Microscopic pathology: Examines tissues and cells under a microscope, focusing on cellular morphology, abnormalities, and specific cell types.
- Molecular pathology: Explores disease at the genetic and molecular levels, identifying genetic defects, mutations, and other related changes.
Branches of Pathology
- Surgical Pathology: Diagnoses abnormal tissues or lesions removed during surgery.
- Anatomic Pathology: Examines disease presence, cause, impact, and mechanisms using various techniques.
- Clinical Pathology: Uses lab analyses of blood, urine, and other body fluids for disease diagnosis and monitoring.
- Forensic Pathology: Applies pathology principles to legal investigations, determining cause and manner of death.
- Infectious Disease Pathology: Focuses on the effects of infections and diseases on body tissues and organs.
- Cardiovascular Pathology: Studies heart and blood vessel diseases.
- Neurological Pathology: Investigates brain and nervous system diseases.
Diagnostic Methods in Pathology
- Histological analysis: Examines stained tissue sections under a microscope to assess cells and tissues.
- Immunohistochemistry: Detects the presence and location of specific proteins within cells using antibodies.
- Immunofluorescence: Locates specific antigens in tissues and cells using fluorescent dyes and antibodies.
- Cytological analysis: Examines cells from body fluids (blood, sputum) to identify abnormalities.
- Molecular techniques (PCR, DNA sequencing): Reveal genetic changes causing disease.
- Electron microscopy: Creates high-resolution images of cellular structures and subcellular components, aiding in diagnoses not observable by light microscopy.
Key Concepts & Principles in Pathology
- Cellular adaptations: Cells adjust to stress for survival (atrophy, hyperplasia, hypertrophy, metaplasia).
- Cell injury and death: Cellular response to injurious stimuli.
- Inflammation: Body's reaction to injury or infection (redness, swelling, heat, pain).
- Repair and regeneration: Processes of replacing injured or lost cells and tissues.
- Neoplasia: Abnormal cell growth forming tumors (benign and malignant).
- Genetic Factors: Mutations, genetic defects, and inherited conditions contributing to diseases.
- Environmental Factors: Exposures to harmful substances, toxic chemicals, radiation, or infections as disease causes.
- Pathogenesis: The sequence of events from initial cause to disease presentation.
- Etiology: Study of the cause of a disease.
Importance of Pathology in Healthcare
- Accurate diagnosis: Detects disease in body tissues for confirming diagnoses.
- Treatment planning: Identifying specific diseases allows for treatment plans.
- Prognosis: Determining disease potential outcome for developing treatment and patient counseling.
- Research: Leads to new diagnostic tools, therapies, and understanding of disease mechanisms.
