Study Notes

Introduction to Pathophysiology

Pathophysiology connects basic sciences with clinical medicine, enhancing understanding of diseases and their mechanisms.

Common Pathological Terms

Pathology: The study of diseases.
Disease: An abnormal disturbance of bodily function or structure due to injury.
Pathogenesis: Sequence of events leading to cellular changes and clinical manifestations.
Symptoms: Patient-reported perceptions of disease (e.g., headache).
Signs: Observable indicators detected by a physician.
Syndrome: A cluster of signs and symptoms that characterize a specific disorder.
Etiology: Study of the causes of diseases.
Nosocomial Infections: Hospital-acquired infections (HAI).
Iatrogenic Reactions: Adverse effects resulting from medical treatment.
Idiopathic Diseases: No identifiable causative factor.
Acute Disease: Quick onset, short duration (e.g., pneumonia).
Chronic Diseases: Slow onset, prolonged duration (e.g., hypertension).
Prognosis: Prediction of a disease's course and outcome.

Disease Classifications

Congenital Diseases: Present at birth due to genetic or environmental factors.
Hereditary Diseases: Developmental disorders genetically passed from parents.
Sex-Linked Disorders: Genetic abnormalities on sex chromosomes (e.g., hemophilia).
Autosomal Inheritance: Genetic abnormalities on non-sex chromosomes.
Degenerative Diseases: Pathologies due to bodily deterioration, often age-related (e.g., atherosclerosis).
Metabolic Diseases: Result from disturbed metabolic functions, such as hormonal imbalance (e.g., diabetes).
Traumatic Diseases: Caused by mechanical injuries or environmental extremes (e.g., burns).
Inflammatory Diseases: Body's response to localized injury (e.g., pneumonia).
- Infective Diseases: Caused by microorganisms.
- Toxic Diseases: Due to poisoning by biological substances.
- Allergic Diseases: Excessive reaction of the immune system.
- Autoimmune Disorders: Immune system attacks the body's own tissues (e.g., rheumatoid arthritis).
Neoplastic Diseases: Result in abnormal tissue growth.
- Lesion: Cellular changes in response to disease.
- Benign Neoplasm: Localized, non-invasive tumors.
- Malignant Neoplasm: Invasive tumors that spread.
- Metastasis: Spread of malignant cells to other tissues.
