Study Notes
- Pathology is the study of diseases, bridging basic medical sciences like anatomy and physiology with clinical sciences such as medicine and surgery.
- Disease is defined as a state where an individual shows anatomical, physiological, or biochemical deviations from what is considered normal.
Classification of Diseases
- Congenital and hereditary diseases are one category.
- Acquired diseases include degeneration, inflammation, circulatory disturbances, and tumors.
Key Aspects of Diseases
- Definition of the Disease
- Epidemiology: Study of the distribution and determinants of health-related states or events in specified populations
- Etiology: The causes of the disease
- Pathogenesis: How the disease develops
- Pathologic Changes (Morphology): Structural alterations in cells or tissues
- Symptoms and Signs (Manifestations): Subjective and objective indications of disease
Epidemiology
- Prevalence is the total number of cases in a population.
- Incidence is the count of new cases within a specific time frame in a population
Etiology Components
- Predisposing factors increase susceptibility to disease, like obesity or poor ventilation.
- Exciting factors are directly responsible for a disease.
- Congenital or Hereditary factors: Defective fetal development in uterus.
- Acquired factors come after birth, including exogenous (environmental) factors like microbes and endogenous (internal) factors like endocrine disturbance.
Pathogenesis
- Pathogenesis is the process by which a disease develops, including the mechanisms and sequence of events.
Pathologic Changes (Morphology)
- Pathologic changes are alterations in cells and organs caused by disease.
- Examined tissue can be obtained through biopsy during life or autopsy post-mortem.
- Examination includes gross (macroscopic) and microscopic analysis using light and electron microscopy.
Clinical Signs & Symptoms
- Clinical signs and symptoms reflect the clinical effects of pathological changes.
- A symptom is a subjective complaint reported by the patient, like pain whose experience is not measurable.
- A sign is an objective medical observation made by a physician, such as elevated blood pressure.
Prognosis & Fate
- Prognosis & fate is the expected outcome or forecast of a disease's course and termination.
- Prognosis & fate depends on the disease itself, patient-related factors, and effective management.
Complications
- Complications are additional pathological changes that worsen the original disease.
- These can occur during or after the original disease.
Surgical Pathology
- Surgical pathology involves examining surgical specimens and biopsies.
- Surgical pathology is essential for diagnosis, determining treatment, and assessing therapy effectiveness.
Types of Specimens for Surgical Pathology
- Excision biopsy involves therapeutic surgical removal of an entire lesion.
- Incision biopsy involves surgical removal of a part of a lesion for diagnosis.
- Punch biopsy obtains tissue from superficial lesions.
- Tru-cut biopsy obtains a core of tissue using large-bore needles, sometimes radiologically guided.
- Fine needle aspiration collects fluid from a lesion using a fine needle for cytologic analysis.
- Aspiration of body fluids examines fluids like urine for cytologic analysis.
- Exfoliative cytology involves scraping the surface of a lesion.
- Brush cytology collects cells from all layers of epithelium using a stiff brush.
Fixation
- Immediate specimen fixation is mandatory to preserve morphology, prevent decomposition, minimize microbial growth, and minimize loss of molecular components.
- Formalin (10% formaldehyde buffered to neutral pH) is a widely used fixative.
- Good fixation is vital for satisfactory results in histopathology.
Gross Examination
- In gross examination, recognition of the anatomic landmarks, localization of the lesion, proper sectioning for diagnosis (sampling), and detection of organ changes via radiology occur.
Microscopic Examination
- All cut tissue samples are processed and sectioned on glass slides.
- Sections are stained with Hematoxylin and Eosin (H&E) for microscopic examination.
- Other special stains may be used.
- Immunohistochemistry with specific monoclonal antibodies helps to identify cell products and surface markers.
Intraoperative Consultation
- Rapid microscopic examination of fresh tissue is done during surgery.
- Intraoperative consultation can direct decisions during the operation.
- Methods include frozen section technique preparing histologic slides, and imprint cytologic slides.
