Study Notes

General Pathology: Introduction

Pathology is the scientific study of diseases.
Pathology links scientific principles to medicine.
It is crucial for diagnosis, prognosis, and treatment advice.
Pathology examines disease cause, progression, structural/functional changes, and natural history.

General Pathology (Basic Pathology)

Studies cellular and tissue level changes linked to disease causes.
Focuses on biochemical and structural changes within cells and tissues.

Systemic Pathology

Studies diseases affecting specific organs.
Investigates etiology, pathogenesis, morphology, clinical features, and consequences of diseases within organs.

Clinical Pathology

Focuses on clinical level investigation of illness symptoms and signs.
Includes patient medical history and clinical evaluation.
Uses diagnostic procedures like systematic clinical examination, tests on body fluids (blood, urine, CSF), and investigations.
Aims at accurate diagnosis and treatment plans.

Causes of Diseases

Diseases are grouped by congenital/genetic (inherited), acquired causes (trauma, infections), nutritional/environmental factors (chemical, physical), aging, and neoplastic factors (cancer).

Methods in Pathology

Histopathology: Examination of tissues under a microscope.
Cytology: Examination of cells.
Hematology: Examination of blood.
Clinical Biochemistry: Examination of blood and body fluids for chemical components.
Microbiology: Examination for infectious microorganisms.
Immunohistochemistry/immunofluorescence: Identification of proteins and cell markers.
Cytogenetics: Examination of cell chromosomes.
Forensic pathology/autopsy: Examinations for cause of death and medico-legal issues.
Toxicology: Identifying and studying the effects of poisons.

Techniques in Pathology

Anatomic pathology: Studies gross appearance of organs, microscopic examination of tissues (light microscopy ,immunohistochemistry, electron microscopy).
Special stains: These enhance visualization of specific structures or components (e.g., H&E, reticulin, PAS, Giemsa, Perl's).
Electron microscopy (EM): Detailed examination of cellular structures (organelles) to diagnose disorders and detect viruses.
Application of EM in diagnostic pathology: Commonly in renal biopsies, evaluating tumor development, and studying skin disorders.
Forensic Pathology/Autopsy: Examines a dead body to determine cause of death. Includes a post-mortem examination.
