Study Notes
Pathology: The Study of Disease
- Pathology is the scientific study of disease, derived from the Latin words "patho" (disease) and "logy" (study).
- Disease is defined as an abnormal variation in body structure or function.
Four Aspects of Disease Study
-
Etiology: The cause of the disease.
- Primary Etiology: Known cause.
- Idiopathic: Unknown cause.
-
Pathogenesis: The mechanism by which the cause produces disease manifestations.
- Occurs during the latent or incubation period.
-
Morphologic Changes: Structural alterations in cells or tissues.
- Gross changes: Visible to the naked eye.
- Microscopic changes: Visible only with a microscope.
- Specific changes can aid in disease diagnosis.
- Lead to functional alterations, and disease symptoms/signs.
- Influence organ function, determining disease course and prognosis.
- Functional Derangements and Clinical Significance: The impact of the disease on organ function and resulting symptoms and signs.
Diagnostic Techniques in Pathology
- Histopathology: Tissue examination.
- Cytopathology: Cell examination.
- Hematopathology: Blood examination.
- Immunohistochemistry: Using antibodies to detect specific molecules.
- Microbiological examination: Identifying microorganisms.
- Biochemical examination: Analyzing bodily chemicals.
- Cytogenetics: Studying chromosomes.
- Molecular techniques: DNA and RNA analysis.
- Autopsy: Post-mortem examination.
