Pathology
A branch of medicine that deals with the structural and functional changes in tissues and organs
of the body that cause or are caused by disease.
Pathophysiology
A specific branch of pathology that studies functional or physiologic changes in the body that
results from disease processes.
Anaerobic
Metabolism and function without oxygen
Apoptosis
Normal programmed cell death in tissues
Autopsy
An examination of part or all of a body postmortem
Biopsy
The removal of a small piece of living tissue for microscopic examination to determine a Dx
Endogenous
Originating from within the body
Exogenous
Originating from outside the body
,Gangrene
Necrotic tissue infected by bacteria
Infection
A disease caused by a microorganism
Homeostasis
A relatively stable or constant environment in the body, including BP, temperature, and pH,
maintained by the carious control mechanisms.
Hypoxia
A decrease or insufficient level of oxygen in the tissues
Iatrogenic
Caused by Tx, procedure, or error
Idiopathic
No known cause
Inflammation
The response to tissue damage, indicted by redness, swelling, warmth, and pain
Ischemia
Decreased blood supply to an organ or tissue
Lysis
Destruction of a cell
Lysosomal
Pertaining to a cell containing digestive or lytic enzymes, including lysozyme
Microorganism
Very small living organism, not visible to the naked eye, usually single-celled
Morphologic
The physical size, form, structure, and shape of cells and organs
Probability
,The likelihood or chance of occurrence
Disease
A deviation from the normal state of health or from a state of wellness. The WHO includes
physical, mental, and social well-being in its definition.
Why is a state of health difficult to define?
Because of the genetic differences among individuals as well as the many variations in life
experiences and environmental influences create a variable base.
Seven Steps to Health
1) Be a non-smoker and avoid second-hand smoke
2) Eat 5-10 servings of vegetables/fruit a day. Choose high-fiber, lower-fat foods. If you drink
ETOH, limit your intake to 1-2 drinks per day.
3) Be physically active on a regular basis: This will help you maintain a healthy body weight
4) Protect yourself and family members from the sun
5) Follow cancer screening guidelines
6) Visit your doctor/dentist if you notice any change in your normal state of health.
7) Follow health and safety instructions at home and at work when using, storing, and disposing
of hazardous materials.
The basic building blocks that facilitates the study of a specific disease
1) The signs related to the specific site of damage.
2) The signs related to the pathologic process.
The primary focus in health care
Prevention
Center for Disease Control and Prevention (CDC)
Based in Atlanta, Ga, is primarily concerned with decreasing the incidence of certain diseases.
Their main focus is the awareness of screening programs and collecting data about all types of
disease and provide evidence based recommendations for prevention.
The Three-stage Process to health research
1st stage- "Basic science" in which researchers ID a technology that will work to limit or prevent
the disease process. Carried out in a lab and often requires the use of animals or cell cultures.
2nd stage- Involves a small number of human subject to determine if the therapy is safe.
, 3rd stage- "Clinical Trails" only takes place if the results of the previous research are positive;
majority don't make it.
Single-blind Studies
Only the pt is unaware of which therapy is being given
Double-blind Studies
Neither pt nor the researchers is aware of which Tx is being given. This study is proctored by a
third party.
Evidence-based Research
Research findings that demonstrate merit after the three-stage process. It does not take into
account cost, availability, or social and cultural factors that may influence use and acceptance of
a therapy.
Importance of Hx, SAMPLE
1) May determine Tx,
2) What impact will it have on pt?
3) How's a pt's illness might complicate care? Ex. therapy/drugs, prescription, non-prescription,
herbal items
HPV
Has a prevalence of about 45% in Americans age 20-24. Est. 70-80% of sexually active
Americans will be infected with it at some point in their life. Gardasil, a new vaccine, prevents
types 16, 18, 6, 11 and can help prevent cervical cancer.
How collects reports from health care professionals?
WHO, United States Public Health Service, CDC
Dx
The identification of a specific disease through evaluation of S/S, laboratory test, or other tools.
More than one factor is usually required to make an accurate Dx.
Etiology
Cause of a specific disease
Idiopathic
Cause of disease is unknown
