Study Notes

Pathology Definition

The study of suffering or diease

Key Terms

Logos: The study of reason or divine wisdom
Disease: An impairment of normal function, a manifestation of aberrant physiology.
Pathogenesis: The sequence of events that leads to disease.
Morbidity: Refers to the diseased state, or ill health due to a disease or lack of treatment.
Mortality: Death

Pathology - Bridging Disciplines

Connects basic sciences such as physiology, microbiology, anatomy, and molecular biology with clinical sciences such as surgery, medicine, and dermatology.
Focus on the relationship between structural and functional changes in cells, tissue, organs, and fluids.
Provides information for patient care, from diagnosis to treatment.

Divisions of Veterinary Pathology

Anatomic Pathologist: Examines structural changes in tissue and organs to identify the cause of disease.
Clinical Pathologist: Examines changes in blood (hematology and serum chemistry) and tissue biopsies (cytology) to identify the cause of disease.

History of Pathology

Early 18th and 19th Centuries: Veterinary pathologists were often butchers, laymen, or field veterinarians.
Rudolf Virchow: Known as the father of modern pathology, his work on "Cellular Pathology" was seminal.

Pathology: Diagnostics

Post Mortem/Necropsy: An autopsy on animals which is often used for diagnosis.
Light Microscopy: Used for histology and cytology, with light magnification to observe tissue structure.
- Various stains are used to identify and differentiate tissue structure.
- Resolution: 200 um

Pathology Definitions

Pathos: Suffering or disease
Logos: Study of reason, divine wisdom
Disease: Impairment of normal function, manifestation of aberrant physiology
Pathogenesis: The mechanism in which a sequence of events from a stimulus leads to disease
Morbidity: Diseased state, ill health
Mortality: Death

Pathology: The Study of Disease

Bridging discipline between basic sciences (physiology, microbiology, anatomy, molecular biology, etc.) and clinical sciences (surgery, medicine, dermatology, etc.)
Examines the relationship between changes in structure and function of cells, tissues, organs, and fluids to an underlying disease
Underpins every aspect of patient care, providing information from diagnosis to treatment

Divisions of Pathology in Veterinary Medicine

Anatomic Pathologist: Examines morphological (structural) changes in tissues and organs to identify the cause of disease
Clinical Pathologist: Examines changes in blood (hematology and serum chemistry) and tissue biopsy (cytology) to identify the cause of disease

The Influence of the Greeks

Early Greeks understood the concept of disease and its causes.
The Greeks developed advanced medical practices for the time.

18th and 19th Century Veterinary Pathology

18th and 19th Century veterinary pathologists were skilled butchers, laymen, or field veterinarians.
Rudolf Virchow is considered the father of modern pathology. His work, "Cellular Pathology," revolutionized the field.

Pathology Diagnostics

Post Mortem (autopsy for humans, necropsy for animals): Common diagnostic technique on dead animals, cost-effective and easy to perform for those skilled.
Light Microscopy (Histology and Cytology): Common diagnostic technique. Magnifies light for detailed examination of tissue structure. Different stains highlight and differentiate specific tissues.
Resolution: The minimum distance between two points at which they are visible. For light microscopy, resolution is 200 um.
