Introduction to General Pathology Flashcards
(33 cards)
The study of Disease
Pathology
How is pathology used to understand how disease works?
Diagnose disease by signs and disease prevention
What are the three pathology studies?
Structural, Biochemical, Functional
[changes in the cell>tissue>organ]
In response to injuries agents and deprivations
Abnormal body process with or without characteristic signs
Disease
Where does disease begin?
At the molecular and cellular level
What does/can disease affect?
May affect the whole body or any of its parts
List the four aspects of a disease process that form the core of pathology
- Etiology
- Pathogenesis
- Molecular and morphologic changes
- Clinical manifestations
Term that refers to the CAUSE of disease
Etiology
What are the two major classes of Etiology?
Genetic (intrinsic) and Acquired (extrinsic)
Give examples of genetic (intrinsic) etiologies
Inherited mutations
Disease-associated gene variants
Polymorphisms
Give examples of acquired (extrinsic) etiologies
Infectious
Nutritional
Chemical
Physical
Term that refers to the mechanisms of disease development [sequence of events from initial stimulus to the ultimate expression of the disease in the response of cells or tissues to the etiology]
Pathogenesis
Refers to biochemical and structural alterations induced in the cells and organs of the body
Molecular and morphologic changes
May be characteristic of a disease or diagnostic of an etiologic process
Molecular and morphologic changes
This results from genetic, biochemical and structural changes in cells and tissues
Clinical Manifestations
Clinical Manifestations manifest as functional abnormalities such as:
Signs (animals): you see as a clinician
Symptoms (humans): what the patient feels and tells you
Injury to the cells and to the extra-cellular matrix leads to
Tissue and Organ damage
Term for a concise statement or conclusion concerning the nature, cause, or name of a disease
Diagnosis
Types of diagnosis (Dx)
Clinical Diagnoses Differential Diagnoses (DDx) Morpholgic diagnoses (MDx) Etiologic diagnoses (Edx) Clinical pathologic diagnosis
Based on the case history (Hx), clinical signs, physical examination, and may provide a DDx
Clinical diagnosis
List of diseases that could account for the evidence or lesions of the case
Differential diagnosis (DDx)
Based on the predominant lesion(s) in the tissue(s)
Morphologic diagnosis
List the information provided in a morphologic diagnosis
- Location
- Distribution
- Severity
- Duration
- Nature
Morphologic diagnosis location:
Organ tissue
