Study Notes
Introduction to Pathology
- Pathology is the scientific study of disease.
- The term derives from Latin words: "patho" (disease) and "logy" (study).
- Disease is defined as an abnormal variation in the structure or function of any body part.
- Pathology examines four aspects of disease:
- Etiology (cause of disease)
- Pathogenesis (mechanism of disease)
- Morphologic changes (structural alterations in cells/tissues)
- Functional derangements and clinical significance (impact on function and symptoms)
Etiology
- Etiology is the cause of a disease.
- Primary etiology: the cause of the disease is known.
- Idiopathic: the cause of the disease is unknown.
Pathogenesis
- Pathogenesis describes how the cause produces disease and its symptoms.
- It occurs during the latent or incubation period.
- Pathogenesis leads to changes in structure.
Morphologic Changes
- Morphologic changes describe structural alterations in cells or tissues.
- Gross changes are visible to the naked eye.
- Microscopic changes require a microscope.
- Morphologic changes are particular to specific diseases.
- Pathologists use these to diagnose.
- Morphologic changes cause functional changes and symptoms.
Functional Derangements and Clinical Significance
- Structural changes impact organ function.
- Clinical features (symptoms and signs), course, and prognosis of the disease are determined by this.
Diagnostic Techniques in Pathology
- Pathologists use various techniques to diagnose diseases:
- Histopathology
- Cytopathology
- Hematopathology
- Immunohistochemistry
- Microbiological examination
- Biochemical examination
- Cytogenetics
- Molecular techniques
- Autopsy
