| anaemia, refractory | Anaemia (a shortage of red blood cells) unresponsive to treatment. (12 Dec 1998) |
| anaemia, refractory, with excess of blasts | Chronic refractory anaemia with granulocytopenia, and/or thrombocytopenia. Myeloblasts and progranulocytes constitute 5 to 40 percent of the nucleated marrow cells. (12 Dec 1998) |
| refractory | Not readily yielding to treatment. Origin: L. Refractorius (18 Nov 1997) |
| refractory anaemia | <haematology> A form of myelodysplasia which primarily affects the red cell production by the bone marrow. In some cases the developing red cells show an internal ring of iron granules. These cells are called sideroblasts. Refractory anaemia and refractory anaemia with sideroblasts are the most common forms of myelodysplasia. Origin: Gr. Haima = blood (13 Nov 1997) |
| refractory anaemia with excess blasts | <haematology> A form of myelodysplasia characterised by the build up of immature white blood cells (blasts) in the bone marrow. If the immature cells are particularly numerous it may indicate a chance of transformation to acute leukaemia and the condition is called refractory anaemia with excess blasts in transformation (RAEBt). Acronym: RAEB (13 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) |
