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.
