talipes
See 
clubfoot.
talipes equinovarus
The most common (clas-
sic) form of clubfoot. With this talipes equinovarus,
the foot is turned in sharply, and the person seems
to be walking on the ankle. See 
clubfoot.
talus
The ankle bone, or the ankle itself. The
ankle joint is formed by the talus and the bottom of
the tibia and fibula, which rest upon it.
tamoxifen
An antiestrogen that competes with
estrogen for binding sites in target tissues such as
breast tissue and blocks the effects of estrogen
there. Tamoxifen may be used to treat breast cancer,
help prevent it in women at high risk, and treat
women who have had surgery and radiation therapy
for ductal carcinoma in situ, to lower the risk of
invasive breast cancer arising from the intraductal
carcinoma.
tampon
A pack or pad that is used to stop or col-
lect the flow of blood or other fluids. A tampon may
be made of cotton, sponge, or another material.
Tampons serve in surgery to control bleeding and
are used to stop severe nosebleeds. Vaginal tampons
collect the flow of menstrual blood.
tamponade, balloon
See 
balloon tamponade.
tamponade, cardiac
A life-threatening situation
in which there is such a large amount of fluid (usu-
ally blood) inside the pericardial sac around the
heart that it interferes with the performance of
the heart. If cardiac tamponade is left untreated, the
result is dangerously low blood pressure, shock,
and death. The excess fluid in the pericardial sac
acts to compress and constrict the heart. Cardiac
tamponade can be due to excessive pericardial
fluid, a wound to the heart, or rupture of the heart.
Also known as pericardial tamponade.
tamponade, chronic
A long-standing situation
in which an excess of fluid inside the pericardial sac
combines with thickening of the pericardial sac to
progressively compress the heart and impair its per-
formance.
