Study Notes
Defining Health and Disease
- Health is defined as a state of complete physical, mental, and social well-being, not merely the absence of disease.
- Homeostasis is the body's dynamic equilibrium, maintained by feedback mechanisms.
- All body systems need to be functioning normally and in balance.
Characteristics of Disease
- Signs: Objective physical manifestations (e.g., swelling, redness).
- Symptoms: Subjective manifestations (e.g., pain, weakness).
- Pathology: The study of disease.
- Pathologist: A physician specializing in diagnosing diseases via cell and tissue examination.
- Clinician: The physician or healthcare professional caring for patients.
Disorders and Syndromes
- A disorder is an abnormal condition of the mind or body, often with combined symptoms, physical findings, or lab results linked by a common factor (genetic, biochemical, physiological, or structural abnormality).
- Syndromes are examples of disorders (e.g., Down syndrome, trisomy 21).
Medical Imaging Techniques
- Medical imaging techniques are used for diagnostics.
Course of Disease
- Acute: Short-term illness.
- Terminal: Illness leading to death.
- Chronic: Long-term illness.
- Remission: Period where disease symptoms lessen or disappear.
- Exacerbation: Increase in severity of a disease.
- Relapse: Recurrence of a disease after remission.
- Complication: A new problem arising from an existing disease.
- Sequela: A condition resulting from a previous disease or injury.
Describing the Occurrence of Disease
- Mortality: Number of deaths.
- Morbidity: Incidence of disease (how many people affected).
- Incidence: Number of newly diagnosed cases.
- Prevalence: Percentage of a population affected by a disease at a given time.
- Epidemiology: Study of disease occurrence, transmission, distribution, and control.
- Etiology: Cause of a disease.
- Pathogenesis: How a disease's cause leads to changes resulting in disease.
- Idiopathic: Disease with no recognizable cause.
Chief Causes of Disease (Etiology)
- Hereditary: Passed down through genes.
- Congenital: Present at birth; birth defects from genetic makeup.
- Degenerative: Continuous process of cell changes leading to deterioration.
- Inflammatory: Uncontrolled inflammation causing tissue destruction.
- Autoimmune: Immune system attacks healthy cells.
- Neoplastic: Abnormal growth (malignant or benign).
- Metabolic: Genetically/acquired-determined factors related to obtaining/making energy from food.
- Traumatic: Physical injury/wound.
- Nutritional: Deficiency or excess of nutrients.
