| resistant ovary syndrome | <syndrome> An obsolete term for amenorrhoea associated with hypergonadotrophism and normal ovarian follicles. Synonym: resistant ovary syndrome. Origin: after the surname of the first reported patient (05 Mar 2000) |
| antibiotic-resistant | Indicating microorganisms that continue to multiply although exposed to antibiotic agents. (05 Mar 2000) |
|---|---|
| vancomycin resistant enterococcus | A form of intestinal bacteria (formerly classed under streptococcus faecalis) which is not sensitive to the big gun antibiotic, vancomycin. This organism is usually only fatal in those who are, for reasons of age or infirmity, immunosuppressed. The pathology of the illness is exacerbated when haemosepsis (blood-stream infection) develops. (09 Oct 1997) |
| vasopressin-resistant diabetes | Diabetes insipidus due to inability of the kidney tubules to respond to antidiuretic hormone; X-linked inheritance, with full expression in males and partial defect in heterozygous females. Synonym: vasopressin-resistant diabetes. (05 Mar 2000) |
| vitamin d-resistant rickets | <radiology> X-linked recessive, defect in renal tubular resorption of phosphate, presents at 1 yr, progressive limb deformities X-ray: less severe changes than other rickets, presents later Differential diagnosis features: family hx, normal serum calcium, marked hypophosphataemia (decreased PO4), no secondary hyperparathyroidism (12 Dec 1998) |
| multiple drug resistant tuberculosis | A strain of TB that does not respond to two or more standard anti-TB drugs. MDR-TB usually occurs when treatment is interrupted thus allowing mutations in the organism to occur that confer drug resistance. (09 Oct 1997) |
| drug resistant | Unresponsive to the desired effects of drugs or other therapy for example: irradiation cytotoxic agents or hormones. Drug resistance of cells within tumours is probably the major cause of treatment failure. (16 Dec 1997) |
| tartrate-resistant acid phosphatase | <biochemistry, enzyme> Acid phosphatase is present in bone, prostate, platelets, erythrocytes and spleen. Osteoclasts contain an isoenzyme that is resistant to tartrate, whereas, the isoenzyme in the prostate is sensitive. Tartrate-resistant acid phosphatase is elevated in the serum of patients with primary hypoparathyroidism, Paget disease, vertebral osteoporosis, T-cell lymphoma and in women after oophorectomy. Oestrogen replacement in osteoporotic postmenopausal women is associated with a decrease in tartrate-resistant acid phosphatase of 70% over 3 to 6 months. Acronym: TRAP (16 Dec 1997) |
| tuberculosis, multidrug-resistant | Tuberculosis resistant to chemotherapy with two or more antitubercular agents. The problem of resistance is particularly troublesome in tuberculosis as an opportunistic disease in HIV infection. (12 Dec 1998) |
| ketosis-resistant diabetes | Type II or adult onset diabetes mellitus, in which episodes of ketoacidosis rarely occur. (05 Mar 2000) |
