Exclamation point hair
Exclamation point hair is a key diagnostic finding in a disorder called alopecia areata. Alopecia areata is patchy baldness (alopecia means baldness and areata means occurring in patches) which typically begins with patchy hair loss on the scalp and sometimes progresses to complete baldness and even loss of body hair. The hair loss tends to be rather rapid and asymmetrical and is different than male pattern baldness.Alopecia areata affects both males and females. It tends to occur most often in children and young adults but older individuals can also be affected.The most common pattern of alopecia areata is one or more spots of hair loss on the scalp. There is also a form with more generalized thinning. When all of the scalp hair is lost, it is called alopecia totalis. Loss of all of the hairs on the body is called alopecia universalis.
Excrescence
An abnormal outgrowth as, for example, a wart.
Exemestane
An oral antiestrogen. Exemestane inhibits the enzyme aromatase in the adrenal glands that produces the estrogens (estradiol and estrone) and thereby lowers their levels.
Exercise test
A test (sometimes called the treadmill test or exercise treadmill test) in which a continuous electrocardiogram (ECG or EKG) recording of the heart is made as the patient performs increasing levels of exercise on the treadmill which is tilted to produce the effect of going up a small hill. The patient can stop the test at any time, if necessary. Afterwards the patient has heart and blood pressure checked. There is very little risk in taking the test in healthy persons -- no more than if a person walks fast or jogs up a big hill. Medical professionals should be present in case something unusual happens during the test. The exercise test screens for the presence of narrowed coronary arteries that can limit the supply of oxygenated blood to the heart muscle during exercise. The test also detects abnormal heart rhythms (arrhythmias).
Exercise treadmill
Exercise on a treadmill, a machine with a moving strip on which one walks without moving forward. A treadmill was originally a wide wheel turned by the weight of people climbing on steps around its edge, used in the past to provide power for machines or as a punishment in prisons.
