| Schiff-Sherrington phenomenon | When the spinal cord is transected in the midthoracic region or a little lower, the stretch and other postural reflexes of the upper extremity become exaggerated; if the transection is made in the sacral cord, a similar effect is observed in the lower limbs. The effect is regarded as a release phenomenon, i.e., release from an inhibitory influence normally exerted by the spinal segments below the transection. (05 Mar 2000) |
| schilder syndrome | <radiology> Sudanophilic leukodystrophy, males (2:1), onset prepuberty, rapidly progressive demyelinating disease, weakness may lead to paralysis, apathy may lead to stupor, death usually in months, occipital and temporal most severely affected (12 Dec 1998) |
| Schilder's disease | Term used to describe at least two separate disorders described by Schilder: 1) Diffuse sclerosis or encephalitis periaxialis diffusa; a nonfamilial disorder affecting primarily children and young adults and characterised by progressive dementia, visual disturbances, deafness, pseudobulbar palsy, and hemiplegia or quadriplegia. Most patients die within a few years of onset; pathologically, there is a large, asymmetrical area of myelin destruction, sometimes involving an entire cerebral hemisphere, and typically with extension across the corpus callosum. 2) The leukodystrophies. Synonym: encephalitis periaxialis diffusa, Flatau-Schilder disease. (05 Mar 2000) |

| schiller | <chemical> The peculiar bronzelike luster observed in certain minerals, as hypersthene, schiller spar, etc. It is due to the presence of minute inclusions in parallel position, and in sometimes of secondary origin. <chemical> Schiller spar, an altered variety of enstatite, exhibiting, in certain positions, a bronzelike luster. Origin: G, play of colours. Source: Websters Dictionary (01 Mar 1998) |
| Schiller's test | A test for nonglycogen-containing areas of the portio vaginalis of the cervix, which may be the site of early carcinoma; such areas fail to stain dark brown with iodine solution; loss of glycogen due to erosion and other benign conditions may also give a positive result.

| schilling test | <investigation> This test measures the amount of vitamin B12 in the urine after ingesting a dose of B12. This test evaluates vitamin B12 absorption. The cells in the stomach produce a substance known as intrinsic factor. This substance combines with B12 to allow absorption in the distal ileum. The patient is given a small dose of radioactive B12 which can then be detected in the patients urine. Pernicious anaemia is the clinical result of B12 deficiency. Conditions that can result in an abnormal Schilling test include: deficiency of intrinsic factor, malabsorption or the development of an antibody to intrinsic factor. The Schilling test can be performed with or without administration of intrinsic factor to determine what the underlying cause for pernicious anaemia. Laxative use, renal insufficiency and hypothyroidism can all interfere with the results of this test. (27 Sep 1997) |
