| latent syphilis | Infection with Treponema pallidum, after the manifestations of primary and secondary syphilis have subsided (or were never noticed), before any manifestations of tertiary syphilis have appeared. (05 Mar 2000) |
| latent tetany | A rather vague disorder recognised more in Europe than in the U.S. Consisting of a number of non-specific complaints, including generalised weakness, hand and foot cramping, distal paresthesia, anxiety, and depression. Some think it is a "normocalcaemic tetany"; others consider it "chronic hyperventilation syndrome." Typically with certain provoking procedures (e.g., limb ischemia, hyperventilation) in which case, obvious tetany develops. See: Trousseau's sign, Chvostek's sign, Erb sign. Synonym: crytotetany, spasmophilia. (05 Mar 2000) |
| latent typhoid | walking typhoid |
| latent virus | <virology> Virus integrated within host genome but inactive: may be reactivated by stress such as ultraviolet irradiation. (18 Nov 1997) |
| latent zone | That portion of the cerebral cortex, the stimulation of which produces no movement and a lesion of which produces no symptoms; mainly the more anterior areas of the frontal lobes. (05 Mar 2000) |
| adrenal gland insufficiency | <endocrinology> A condition that results from the inadequate production of adrenal hormones (see Addison's disease). (27 Sep 1997) |
| adrenal insufficiency | <endocrinology> A condition that results from the inadequate production of adrenal hormones (see Addison's disease). (27 Sep 1997) |
| aortic insufficiency | A congenital or acquired heart valve abnormality that results in the abnormal back flow of blood in the aorta, through an incompetent aortic valve and into the left ventricle. Chronic aortic insufficiency leads to enlargement of the left ventricle and pulmonary congestion. If left uncorrected, congestive heart failure will result. Aortic valve replacement is eventually necessary in most cases of significant valvular incompetence. (27 Sep 1997) |
| aortic valve insufficiency | Backflow of blood from the aorta into the left ventricle, owing to imperfect functioning of the aortic semilunar valve. (12 Dec 1998) |
| cardiac insufficiency | A condition where there is ineffective pumping of the heart leading to an accumulation of fluid in the lungs. Typical symptoms include shortness of breath with exertion, difficulty breathing when lying flat and leg or ankle swelling. Causes include chronic hypertension, cardiomyopathy and myocardial infarction. (27 Sep 1997) |
| valvular insufficiency | A leaky state of one or more of the cardiac valves, the valve not closing tightly and blood therefore regurgitating through it. Synonym: valvular incompetence, valvular insufficiency. (05 Mar 2000) |
| pancreatic insufficiency | Not enough of the digestive enzymes normally secreted by the pancreas into the intestine. Pancreatic insufficiency is a hallmark of cystic fibrosis. (12 Dec 1998) |
| velopharyngeal insufficiency | Failure of the soft palate to reach the posterior pharyngeal wall. It may be caused by cleft palate surgery, palatal or pharyngeal abnormalities or injury, or neuromuscular dysfunction of the velopharyngeal sphincter. It causes hypernasality of speech. (12 Dec 1998) |
| venous insufficiency | <cardiology, surgery> A condition in which the vein do not channel the flow of blood adequately. most often this condition is seen in the veins of the lower extremities. Symptoms include leg swelling, leg pain and muscle cramps. This condition can predispose to venous thrombosis. (12 Jan 1998) |
