| Rothera's nitroprusside test | A test for ketone bodies; 5 ml of fresh urine are saturated with solid ammonium sulfate and mixed with 10 drops of freshly prepared 2% sodium nitroprusside solution, which is then mixed with 10 drops of concentrated ammonia water and allowed to stand for 15 min; the presence of acetoacetic acid, or of larger concentrations of acetone, is indicated by the development of a blue-purple colour.

| Rothia | A genus of nonmotile, nonsporeforming, non-acid-fast, aerobic to facultatively anaerobic bacteria (family Actinomycetaceae) containing Gram-positive, coccoid, diphtheroid, or filamentous cells; metabolism is fermentative, and glucose fermentation yields primarily lactic acid but no propionic acid. These organisms are normal inhabitants of the human oral cavity and are opportunistic pathogens. The type species is Rothia dentocariosa. Origin: G. D. Roth Rothia dentocariosa, rare cause of infective endocarditis in humans. (05 Mar 2000) |
| Rothmund's syndrome | <syndrome> Atrophy, pigmentation, and telangiectasia of the skin, usually with juvenile cataract, saddle nose, congenital bone defects, disturbance of hair growth, hypogonadism; autosomal recessive inheritance.

| Rothmund, August von | <person> German physician, 1830-1906. See: Rothmund's syndrome, Rothmund-Thomson syndrome. (05 Mar 2000) |
| rothmund-thomson syndrome | <syndrome> A genetic disorder with numerous features affecting skin (premature aging, excess pigmentation, dilated blood vessels),eyes (juvenile cataract), nose (saddle nose), teeth (maldeveloped), skeletal system (congenital bone defects) hair (abnormal), gonads (underdevelopment) limbs (soft tissue contractures), growth (short stature), blood (anaemia) and a tendency to develop a type of bone cancer (osteogenic sarcoma). The rts gene is on chromosome 8. The syndrome is recessive so to be affected with rts a child has to have two rts genes, one from each parent. Rts is also called poikiloderma atrophicans and cataract. (12 Dec 1998) |
