Webster's New World Medical Dictionary

tick-borne disease
A disease that is carried by or
caused by a tick. Examples of tick-borne diseases in
the US include babesiosis (a malaria-like infection),
ehrlichiosis, Lyme disease, relapsing fever (also
called tick fever, most common in the western US),
Rocky Mountain spotted fever, tick paralysis, and
tularemia (rabbit fever). Anyone working in the out-
doors, especially in areas with tall grasses, shrubs,
low-hanging branches, or leaf mold, is susceptible to
being bitten by a tick. Ticks do not jump, crawl, or
fall onto a person. They are picked up when clothing
or hair brushes leaves or other objects that they are
on. Ticks are generally found within 3 feet of the
ground. After a tick is picked up, it crawls until it
finds a likely site to feed. Ticks often find spots at the
back of the knee, near the hairline, and behind the
ears. The best way to prevent tick-borne diseases is to
avoid being bitten by ticks.

tilt-table test
A test that involves placing a
patient on a table with a foot-support, tilting the
table upward, and measuring the blood pressure
and pulse. Symptoms are recorded with the patient
in diverse positions. The tilt-table test is designed to
detect postural hypotension (orthostatic hypoten-
sion), a condition caused by changing body position
from a prone, supine, or sitting position to a more
vertical position. Poor tone of the nerves of the legs
can cause a disproportionate distribution of blood
to the legs, instead of to the brain, so the patient
feels lightheaded and may even faint. See also 
syn-
cope; syncope, situational; vasovagal reaction.
