Study Notes

Pathology: The Science of Studying Diseases

Etiology, Pathogenesis, Morphological changes, and Fate & Complications are the main components of studying diseases

Inflammation

Definition: Dynamic response of vascularized living tissue to injury
Aim: Protective mechanism to get rid of microbes and necrotic tissue
Characteristics: Red, hot, pain

Vascular Reaction in Inflammation

Aim: Increase blood flow and vascular permeability
Mechanisms:
- Vasodilation with increased blood flow
- Increase vascular permeability (protein and cells) through:
  - Contraction of endothelial cells
  - Endothelial cell injury
  - Transcytosis

Causes of Inflammation

Physical: Trauma, Heat, Radiation, Cold
Chemical: Acids, Alkali, Poisons
Infection: Bacteria, Viruses, Fungi, Parasites
Immunological: Antigen-antibody, Cell-mediated

Types of Inflammation

Acute Inflammation:
- Definition: Rapid host response to deliver leukocytes and plasma protein to site of infection or tissue injury
- Characteristics: Sudden onset, rapid, short duration, prominent vascular response
Chronic Inflammation:
- Characteristics: Gradual onset, slow, long duration, less prominent vascular response

Leukocytes Journey

Steps:
- Increase vascular permeability
- Leukocytes migration
- Chemotaxis (movement of cells towards a chemical stimulus)
- Phagocytosis (engulfing of foreign particles or bacteria)

Abscess

Definition: Localized collection of pus
Mechanism of formation: Accumulation of leukocytes and dead tissue
Example: Pus-filled cavity in the skin
Fate: May resolve or lead to chronic inflammation

Comparison between Abscess and Cellulitis

Abscess: Localized collection of pus
Cellulitis: Inflammation of subcutaneous tissue
