Pathology
• Study of the nature and cause of disease and the condition produced by disease (deviation from
normal health)
Pathophysiology
• Study of how normal physiological processes are altered by disease
Firm foundation in anatomy and physiology is particularly important when a disease affects several
organs or systems
Health care professions require knowledge in pathology and pathophysiology so that they have a
considerable foundation of information to apply in their speciality area
• Confer with other HCPs
• Apply knowledge to image and/or treat their patient correctly
• To be able to care and empathize of patients appropriately
Diagnosis
• Identification of a specific disease through the evaluation of signs and symptoms, lab tests,
imaging tests, etc…
Prognosis
• Refers to probability for recovery (prediction or forecast regarding the possible outcome of the
course and the end of the disease)
Etiology
• Cause of disease
• May be one or several
• Examples:
o Congenital
o Inherited
o Microorganisms
o Immune disorder
o Degenerative disorder
o Degenerative
o Malignancy
o Trauma
Iatrogenic
• Condition/disease caused by the treatment/ activities of a physician or surgeon (medical
treatment)
• Benefit/risk needs to be assessed
• Examples:
o Bladder infection after catheterization
o Vessel damage after angiogram
o Complication from radiation therapy
Idiopathic
• Cause of the disease is unknown
Predisposing Factors
• Susceptibility to disease or indicating a high risk of a high disease
• Example:
o Occupational exposure
Precipitating Factors
• Condition/circumstance that triggers an acute episode
• if doing normal activities, you may not show any signs/symptoms
• Example:
o Angina attack
Prevention
• Keeping an illness from happening
• Example:
o Vaccines
o Diet
o Lifestyle modification
Pathogenesis
• Development of the disease
• “sequence of events”
• Tissue changes
Acute
• Sudden onset of disease or short-termed
• Often with high fever, pain
• Example:
o Appendicitis
Chronic
• Often a milder condition but with a longer term
• Can have acute episodes
Document Summary
Pathology: study of the nature and cause of disease and the condition produced by disease (deviation from normal health) Pathophysiology: study of how normal physiological processes are altered by disease. Firm foundation in anatomy and physiology is particularly important when a disease affects several organs or systems. Identification of a specific disease through the evaluation of signs and symptoms, lab tests, i(cid:373)agi(cid:374)g tests, etc . Prognosis: refers to probability for recovery (prediction or forecast regarding the possible outcome of the course and the end of the disease) Etiology: cause of disease, may be one or several, examples, congenital. Immune disorder: degenerative disorder, degenerative, malignancy, trauma. Iatrogenic: condition/disease caused by the treatment/ activities of a physician or surgeon (medical treatment, benefit/risk needs to be assessed, examples, bladder infection after catheterization, vessel damage after angiogram, complication from radiation therapy. Idiopathic: cause of the disease is unknown.
