AtheliaAbsence of the nipple. Athelia is a rare condition but it is common in certain conditions. Athelia tends to occurs on one side (unilaterally) in children with the Poland sequence and on both sides (bilaterally) in certain types of ectodermal dysplasia.

Condition
The term "condition" has a number of biomedical meanings including the following: 1.An unhealthy state, such as in "this is a progressive condition." 2.A state of fitness, such as "getting into condition." 3.Something that is essential to the occurrence of something else; essentially a "precondition." 4.As a verb: to cause a change in something so that a response that was previously associated with a certain stimulus becomes associated with another stimulus; to condition a person, as in behavioral conditioning.
Ectodermal
Pertaining to the ectoderm or to tissues derived from the ectoderm, one of the three primary germ cell layers that make up the very early embryo. The ectoderm is the outermost of the three layers.
Dysplasia
An abnormality of growth.

Atherectomy
A non-surgical procedure that involves removing plaque from the walls of arteries with a rotating blade.
Atherectomy (Directional Coronary Atherectomy or DCA)
The DCA catheter has a hollow cylinder on the tip with an open window on one side and a balloon on the other. When the catheter is inserted into the narrowed artery, the balloon is inflated, pushing the window against the fatty matter clogging the vessel. A blade (cutter) within the cylinder rotates and shaves off any fat, which protruded into the window. The shavings are caught in a chamber within the catheter and removed. This process is repeated as needed to allow better blood flow.
Atherogenesis
The process of forming atheromas, plaques in the inner lining (the intima) of arteries.
Atheroma
A fatty deposit in the intima (inner lining) of an artery, resulting from atherosclerosis. Also called an atherosclerotic plaque, arterial plaque or, simply, a plaque.
Atheroma:
Large build-up of fat, cholesterol and other substances on the walls of an artery, causing narrowing. Also called plaque.
Atherosclerosis
Also known as arteriosclerosis, atherosclerosis results from the accumulation of cholesterol-laden plaque in artery walls. Plaque accumulation causes a narrowing and a loss of elasticity of the arteries, sometimes referred to as hardening of the arteries.
Atherosclerotic
Pertaining to atherosclerosis, the process of progressive thickening and hardening of the walls of arteries from fat deposits on their inner lining.
Atherosclerotic aneurysm
The most common type of aneurysm, affecting the abdominal portion of the aorta and other large arteries, particularly with age.
Athetosis
Slow, involuntary movements of the hands and feet.
PREVIOUS AND NEXT TERMS--------------------------------------
Ataxia-telangiectasia
"A progressive neurodegenerative genetic disease characterized by cerebellar ataxia (incoordination and lack of balance), ocular telangiectasia (""red eyes"" due to widening of small blood vessels in the conjunctiva), immune defects, and a predisposition to malignancy. Chromosomal breakage is a feature. Ataxia-telangiectasia (A-T) cells are abnormally sensitive to killing by ionizing radiation."

Atenolol
A medication that blocks the action of a portion of the involuntary nervous system that stimulates the pace of the heartbeat. By blocking the action of these nerves, atenolol reduces the heart rate and is useful in treating abnormally rapid heart rhythms. Atenolol also reduces the force of heart muscle contraction, lowers blood pressure, and is helpful in treating angina. It is also used for the prevention of migraine headaches and the treatment of certain types of tremors. The brand name is Tenormin. Generic is available.
ATG
Antithymocyte globulin.
