Study Notes
Pathology
- The scientific study of disease.
- Pathology aims to understand the causes, mechanisms, structural changes, and clinical manifestations of diseases.
Key Aspects of Pathology
-
Etiology: The cause of a disease.
- Primary Etiology: When the cause of a disease is known.
- Idiopathic/Cryptogenic: When the cause of a disease is unknown.
- Pathogenesis: The mechanism by which the cause produces the clinical signs and symptoms.
-
Morphologic Changes: Structural changes in cells or tissues due to disease.
- Gross/Macroscopic Findings: Changes visible to the naked eye.
- Microscopic/Histologic Findings: Changes visible only under a microscope.
-
Functional Derangements & Clinical Significance: The functional effects of damage caused by disease, leading to clinical signs and symptoms.
- Symptoms: Subjective experiences reported by the patient.
- Signs: Objective findings observed by the doctor during examination.
- Clinical Features: The combination of signs and symptoms.
Etiologic Factors
- Congenital: Existing at birth or before birth.
- Acquired: Developed after birth, including infectious, inflammatory, chemical, physical, and other factors.
Diagnostic Techniques
-
Histopathology: Examination of tissues under a microscope.
- Involves obtaining tissue through biopsies or surgical excision.
- Processed and stained to create thin slices for microscopic analysis.
- Cytopathology: Study of cells from various body sites to identify the cause of disease.
- Hematological Examination: Examination of blood cells to study diseases related to them.
- Immunohistochemistry: Staining technique using antibodies to identify specific antigens in cells or tissues.
- Microbiological Examination: Identification of microorganisms in body fluids or tissues.
- Biochemical Examination: Measurement of changes in substances (proteins, sugars, oxygen, etc.) in blood and urine to diagnose diseases.
- Clinical Genetics (Cytogenetics): Study of chromosomal abnormalities.
- Molecular Techniques: Detection of genetic diseases.
- Autopsy/Forensic Pathology: Examination of a dead body to determine the cause of death.
