Six Medical Terms likely encountered by a Medical
Assistant:
1. Symptom: (L. and Gr. Symptoma
Anything that has befallen one). Subjective evidence of a disease or a patient’s
condition.
Explanation: a symptom is an
abnormal condition that the patient experiences as a result of disease. For example
headache can be a symptom of brain tumor, abdominal pain a symptom of
appendicitis.
2. Sign: (L. signum). Any
objective evidence of a condition or disease that is perceptible to the examining
physician, as opposed to the subjective sensation (symptom) of the
disease.
Explanation: A heart murmur (heard
through the stethoscope) may be a sign of valvular heart disease, for which chest pain
on exertion might be a symptom.
3. Acute: (L.
acutus sharp). Having a short and relatively severe
course.
Explanation: As used in medicine,
“acute” refers to brief duration or sudden onset of symptoms or disease, and not so much
as the severity of the symptom or condition.
4.
Chronic: (L. chronicus, Gr. Chronos time). Persisting over a long
time.
Explanation: A chronic disease or
condition is one that has been present for a long time, usually weeks to months rather
than days or hours (acute). For example, appendicitis is considered an acute disease
(acute appendicitis), whereas cancer has a chronic
course.
5. Etiology: (Gr. Aitia cause +
logy). The study or the theory of the factors that cause disease; and the method of
their introduction to the host. The cause(s) or origin of a disease or
disorder.
Explanation: A medical chart might
state that a disease or condition has an infectious etiology, indicating that the
disease is caused by the introduction of infectious
organisms.
6. Iatrogenic: (iatro + Gr. Gennan
to produce). Resulting from the activity of physicians. Currently applied to any
adverse condition in a patient occurring as the result of treatment by a physician or
surgeon; especially to infections acquired by the patient during
treatment.
Example: The patient’s sepsis (blood
poisoning) was iatrogenic, occurring as a complication of his infected intravenous fluid
line.
