| exercise tolerance | The exercise capacity of an individual as measured by endurance (maximal exercise duration and/or maximal attained work load) during an exercise test. (12 Dec 1998) |
|---|---|
| exercise treadmill | A continuous EKG recording of the heart as the patient performs increasing levels of exercise. The exercise treadmill permits the detection of abnormal heart rhythms (arrhythmias) and provides a screening test for the presence of narrowed arteries to the heart (coronary arteries). Narrowing of these arteries can limit the supply of oxygenated blood to the heart muscle during exercise. (12 Dec 1998) |
| acute urticaria | Urticaria accompanied by slight constitutional symptoms. Synonym: acute urticaria, urticaria acuta, urticaria febrilis. (05 Mar 2000) |
| papular urticaria | A sensitivity reaction to insect bites, especially human and pet fleas, seen mostly in young children as wheals followed by papules on exposed areas. Synonym: lichen urticatus, prurigo infantilis, urticaria papulosa. (05 Mar 2000) |
| giant urticaria | A vascular reaction involving the deep dermis or subcutaneous or submucal tissues, representing localised oedema caused by dilatation and increased permeability of the capillaries and characterised by development of giant wheals. (18 Nov 1997) |
| vibratory urticaria | A form of urticaria that occurs in response to vibratory stimuli. (05 Mar 2000) |
| cholinergic urticaria | A form of physical or non-allergic urticaria initiated by heat (e.g., hot baths, physical exercise, pyrexia, exposure to sun or to a warm room) or by excitement; the rather distinctive lesions consist of pruritic areas 1 to 2 mm in diameter surrounded by bright red macules. Synonym: heat urticaria. (05 Mar 2000) |
| chronic urticaria | A form of urticaria in which the wheals recur frequently, or persist. Synonym: urticaria chronica. (05 Mar 2000) |
| cold urticaria | Wheal formation that develops after exposure to lowered temperatures, with or without demonstrable passive-transfer antibodies. Synonym: congelation urticaria. (05 Mar 2000) |
| congelation urticaria | Wheal formation that develops after exposure to lowered temperatures, with or without demonstrable passive-transfer antibodies. Synonym: congelation urticaria. (05 Mar 2000) |
| pressure urticaria | Urticaria of unknown aetiology occurring after local pressure on the skin. (05 Mar 2000) |
| heat urticaria | A form of physical or non-allergic urticaria initiated by heat (e.g., hot baths, physical exercise, pyrexia, exposure to sun or to a warm room) or by excitement; the rather distinctive lesions consist of pruritic areas 1 to 2 mm in diameter surrounded by bright red macules. Synonym: heat urticaria. (05 Mar 2000) |
| solar urticaria | A form of urticaria resulting from exposure to specific light spectra; e.g., sunlight; some patients have passive-transfer antibodies and others do not. (05 Mar 2000) |
| factitious urticaria | A form of urticaria in which whealing occurs in the site and in the configuration of application of stroking (pressure, friction) of the skin. Synonym: autographism, dermagraphy, dermatography, dermographia, dermographism, dermography, factitious urticaria, skin writing, urticaria factitia. Origin: dermato-+ G. Grapho, to write (05 Mar 2000) |
| febrile urticaria | Urticaria accompanied by slight constitutional symptoms. Synonym: acute urticaria, urticaria acuta, urticaria febrilis. (05 Mar 2000) |
