Study Notes
- Aetiology and pathogenesis of diseases: Overview of the causes, mechanisms, manifestations, and consequences of diseases
- Aetiology:
- Cause of diseases
- Genetic: Inherited or acquired during conception, embryogenesis, or post-natal life
- Environmental: Infectious agents (bacteria, viruses, fungi, parasites), chemicals, or physical factors (radiation, mechanical trauma)
- Multifactorial: Combination of genetic and environmental factors
- Unknown aetiology: Classified as idiopathic, primary, essential, spontaneous, or cryptogenic
- Pathogenesis:
- Mechanism through which aetiology operates to produce pathological and clinical manifestations
- Examples: Inflammation, degeneration, carcinogenesis
- Manifestations of disease:
- Characteristics of diseases: structural and functional features, symptoms, signs, complications, and prognosis
- Complications: secondary or distant effects of a disease
- Prognosis: anticipated outcome of the disease
- Epidemiology:
- Determination of causes, incidence, mortality, and characteristic behavior of disease outbreaks affecting human populations
- Morbidity: disease state of an individual or incidence of illness in a population
- Mortality: probability of death as a result of the disease
- Prevalence: total number of cases of a disease in a specified population at a designated time
- Relationship between Aetiology, Pathogenesis, and Disease:
- Disease: structural and functional damage
- Complication: secondary or distant effect of the disease
- Terminology:
- Symptoms: patient complaints
- Signs: physical findings
- Syndrome: aggregate of signs and symptoms or a combination of lesions required for diagnosis
- Lung cancer: specific example of a disease with aetiology, pathogenesis, manifestations, and epidemiology.
