Study Notes
Definition of Pathology
- Derived from Greek terms: "pathos" meaning suffering and "logos" meaning study.
Branches of Pathology
- Histopathology (anatomical pathology): Study of diseased tissues.
- Forensic Pathology: Application of pathology to legal questions and investigations.
- Clinical Pathology: Involves microbiology, mycology, virology, and parasitology to diagnose diseases.
- Chemical Pathology: Focuses on the biochemical analysis of body fluids for disease identification.
- Molecular Pathology: Examines the molecular basis of disease.
Aspects of Disease
- Etiology: The cause of disease, which can be genetic (inherited mutations) or acquired (infectious agents, nutritional deficiencies).
- Pathogenesis: Process of development and progression of disease at the cellular and molecular levels.
- Morphologic Changes: Structural alterations in cells and tissues linked to specific diseases.
- Functional Derangements: Changes in normal function resulting in clinical manifestations like symptoms and signs.
Etiology
- Can be categorized as genetic (e.g., hereditary mutations) or acquired (e.g., infections, chemicals).
- Typically multifactorial, involving multiple factors contributing to disease onset.
Pathogenesis
- Involves the sequence of cellular, biochemical, and molecular events triggered by harmful agents impacting cells or tissues.
Morphologic Changes
- Structural alterations that characterize a disease or help diagnose it through histopathology.
Functional Derangements
- Reflect the clinical manifestations that can progress and determine the clinical course and outcomes of diseases.
How Disease is Studied in Histopathology
- Involves several methods:
- Postmortem examinations to diagnose diseases after death.
- Cytology: Study of individual cells to assess disease.
- Histology: Examination of tissue sections to identify disease.
- Use of request forms to guide diagnostic processes.
- Collaboration within Multidisciplinary Teams (MDTs) to integrate expertise.
Infection Prevention
- Implements universal precautions to minimize risk of infectious spread.
- Employs biosafety measures to protect laboratory staff and patients.
- Ensures containment protocols are followed.
- Personal Protective Equipment (PPE) is used to safeguard against exposure.
Ethical Aspects in Pathology Practice
- Addresses ethical considerations in anatomical, clinical, and forensic pathology, ensuring integrity and respect for individuals involved.
