    Study Notes

    Introduction to Pathology

    • Pathology studies abnormalities in anatomy and physiology due to disease, focusing on structural, biochemical, and functional changes.
    • The term originates from Greek: 'Pathos' (suffering) and 'logos' (study).
    • Illness reflects individual reactions to disease through symptoms.

    Categories of Disease

    • Developmental
    • Inflammatory
    • Neoplastic
    • Degenerative

    Key Aspects of Disease

    • Definition: Disease signifies structural or functional abnormalities.
    • Epidemiology: Investigates when and where diseases occur.
    • Etiology: Examines the causes of diseases.
    • Pathogenesis: Describes disease evolution mechanisms.
    • Morphology: Involves examining structural changes in tissues.
    • Functional Consequences: Impact of the disease on normal body functions.
    • Management: Approaches for treatment.
    • Prognosis: Expected outcomes - cure, morbidity, or mortality.
    • Prevention: Strategies to avert disease.

    Terminology in Pathology

    • Patient: An individual afflicted by disease.
    • Lesion: Characteristic changes in tissue or cells.
    • Morphology: Study of diseased tissue appearance, both gross and microscopic.
    • Symptoms: Subjective manifestations reported by patients.
    • Signs: Objective findings observed by clinicians.
    • Pathognomonic: Specific signs indicative of a disease.
    • Syndrome: A cluster of associated clinical features.
    • Acute Illness: Sudden onset, potentially self-resolving.
    • Chronic Disease: Gradual onset, prolonged duration.

    Cell and Tissue Responses

    • Elimination of Cells: Involves apoptosis and clearance of mature immune cells after their function.
    • DNA Damage: Caused by radiation, drugs, temperature extremes, and hypoxia.

    Dysregulated Apoptosis

    • Disorders arising from inadequate or excessive apoptosis may lead to abnormal cell survival or tissue accumulation.
    • Accumulation Examples: Carbon in lungs, tattooing, calcifications.

    Specific Conditions

    • Dysplasia Cervix: Abnormal changes in cervical epithelium linked to chronic inflammation.
    • Fatty Change of Liver (Steatosis): Abnormal triglyceride accumulation in hepatic cells, often due to toxins, malnutrition, diabetes, obesity, or alcohol.

    Pigments in Pathology

    • Endogenous Pigments: Produced internally, accumulating over time (e.g., lipofuscin, melanin, bilirubin, haemosiderin).
    • Exogenous Pigments: Originating externally, such as from pollutants or tattoos.

    Jaundice

    • Characterized by a yellow sclera due to bodily excess bilirubin, indicating possible liver dysfunction.
