| Sturge-Kalischer-Weber syndrome | <syndrome> A congenital syndrome consisting of nevus flammeus of the face, haemangiomas of the leptomeninges and choroid, and late glaucoma. It is often associated with intracranial calcification, mental retardation, contralateral hemiplegia, and epilepsy. (12 Dec 1998) |
| sturge-weber-dimitri syndrome | <radiology> Encephalotrigeminal angiomatosis, leptomeningeal capillary-venous angiomatosis, with subjacent cortical calcification, ipsilateral port-wine stains (venous angioma) of face, ipsilateral congenital glaucoma, contralateral focal sz (90%) and hemiparesis (33-66%), subnormal mentation (50%) (12 Dec 1998) |

| syndrome, klippel-trenaunay-weber | A congenital malformation syndrome characterised by the triad of asymmetric limb hypertrophy, haemangiomata, and nevi. Asymmetric limb hypertrophy is enlargement of one limb and not the corresponding limb on the other side, the enlarged limb being 3 times more likely to be a leg than an arm in ktw; and the limb enlargement is of bone as well as soft tissue. The haemangiomas, abnormal nests of blood vessels that proliferate inappropriately and excessively, cover a remarkable range from small innocuous capillary haemangiomas ( strawberry marks ) to huge cavernous haemangiomas. The nevi are pigmented moles on the skin; in ktw there are often also dark linear streaks on the skin, streaks due to too much pigment. There can be other abnormalities but the triad is the consistent clinical centrepiece of the disease. most persons with ktw have an enlarged leg and do relatively well without treatment or, for example, with only compression from an elastic stocking. Skin ulcers and other skin problems can occur over the swollen leg. Usually, the treatment is conservative. Surgery is almost never needed. The only possible exceptions are the very rare situations in which the leg reaches gigantic proportions or secondary clotting difficulties arise (due to trapping and destruction of blood platelets in a huge haemangioma). Then, amputation may become necessary. The cause of ktw syndrome is unknown. (12 Dec 1998) |
| osler-weber-rendu disease | <disease> An inherited disease characterised by thin blood vessel walls in the nose, skin and gastrointestinal tract. This condition ins associated with a high risk of bleeding complications. (27 Sep 1997) |
| Fechner-Weber law | The intensity of a sensation varies by a series of equal increments (arithmetically) as the strength of the stimulus is increased geometrically; if a series of stimuli is applied and so adjusted in strength that each stimulus causes a just perceptible change in intensity of the sensation, then the strength of each stimulus differs from the preceding one by a constant fraction; thus, if a just perceptible change in a visual sensation is produced by the addition of 1 candle to an original illumination of 100 candles, 10 candles will be required to produce any change in sensation when the original illumination was one of 1000 candles. Synonym: Fechner-Weber law, Weber's law. (05 Mar 2000) |

| administration, rectal | The insertion of drugs into the rectum, usually for confused or incompetent patients, like children, infants, and the very old or comatose. (12 Dec 1998) |
| cancer, rectal | A malignant tumour arising from the inner wall of the end (rectum) of the large intestine. The third leading cause of cancer in males, fourth in females in the U.S. Risk factors for cancer of the colon and rectum (colorectal cancer) include heredity, colon polyps, and long standing ulcerative colitis. most colorectal cancers develop from polyps. Removal of colon polyps can prevent colorectal cancer. Colon polyps and early cancer can have no symptoms. Therefore, regular screening is important. Diagnosis can be made by barium enema or by colonoscopy with biopsy confirmation of cancer tissue. Surgery is the most common treatment for colorectal cancer. (12 Dec 1998) |
| rectal | <anatomy> Pertaining to the rectum, the distal portion of the large intestine. (18 Nov 1997) |
