| 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) |
|---|---|
| acute rickets | Bone changes seen in infantile scurvy, consisting of subperiosteal haemorrhage and deficient osteoid tissue formation; often used to indicate simultaneous occurrence of rickets and scurvy. Synonym: acute rickets. Hereditary hypophosphatemic rickets, with hypercalciuria, an inherited disorder in which there is a defect in renal tubular reabsorption. (05 Mar 2000) |
| adult rickets | <pathology> A condition marked by softening of the bones (due to impaired mineralisation, with excess accumulation of osteoid), with pain, tenderness, muscular weakness, anorexia and loss of weight, resulting from deficiency of vitamin D and calcium. Origin: Gr. Malakia = softness (18 Nov 1997) |
| refractory rickets | Rickets that does not respond to treatment with usual doses of vitamin D and adequate dietary calcium and phosphorus. Most often due to inherited renal tubular disorder e.g., Fanconi syndrome. Renal rickets, a form of rickets occurring in children in association with and apparently caused by renal disease with hyperphosphatemia. Synonym: pseudorickets, renal fibrocystic osteosis, renal infantilism, renal osteitis fibrosa. (05 Mar 2000) |
| rickets | <rheumatology, orthopaedics> A condition caused by deficiency of vitamin D, especially in infancy and childhood, with disturbance of normal ossification. The disease is marked by bending and distortion of the bones under muscular action, by the formation of nodular enlargements on the ends and sides of the bones, by delayed closure of the fontanelles, pain in the muscles and sweating of the head. Vitamin D and sunlight together with an adequate diet are curative, provided that the parathyroid glands are functioning properly. Origin: Gr. Rhachitis = a spinal complaint (18 Nov 1997) |
| coeliac rickets | Arrested growth, and osseous deformities associated with defective absorption of fat and calcium in coeliac disease. (05 Mar 2000) |
| haemorrhagic rickets | Bone changes seen in infantile scurvy, consisting of subperiosteal haemorrhage and deficient osteoid tissue formation; often used to indicate simultaneous occurrence of rickets and scurvy. Synonym: acute rickets. Hereditary hypophosphatemic rickets, with hypercalciuria, an inherited disorder in which there is a defect in renal tubular reabsorption. (05 Mar 2000) |
| scurvy rickets | infantile scurvy |
| familial hypophosphatemic 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) |
| late rickets | <pathology> A condition marked by softening of the bones (due to impaired mineralisation, with excess accumulation of osteoid), with pain, tenderness, muscular weakness, anorexia and loss of weight, resulting from deficiency of vitamin D and calcium. Origin: Gr. Malakia = softness (18 Nov 1997) |
| 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) |
| resistant | Making or having powers of resistance, resisting. (18 Nov 1997) |
| 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) |
