| leukoedema, oral | A disorder of the buccal mucosa resembling early leukoplakia, characterised by the presence of filmy opalescence of the mucosa in the early stages to a whitish gray cast with a coarsely wrinkled surface in the later stages, associated with intracellular oedema of the spinous or malpighian layer. (12 Dec 1998) |

| leukoplakia, oral | A white patch seen on the oral mucosa. It is considered a premalignant condition and is often tobacco-induced. When evidence of epstein-barr virus is present, the condition is called hairy leukoplakia (leukoplakia, hairy). (12 Dec 1998) |
| lichen planus, oral | Oral lesions accompanying cutaneous lichen planus or often occurring alone. The buccal mucosa, lips, gingivae, floor of the mouth, and palate are usually affected (in a descending order of frequency). Typically, oral lesions consist of radiating white or gray, velvety, threadlike lines, arranged in a reticular pattern, at the intersection of which there may be minute, white, elevated dots or streaks (wickham's striae). (12 Dec 1998) |
| live oral poliovirus vaccine | Inactivated poliovirus vaccine (IPV), an aqueous suspension of inactivated strains of poliomyelitis virus (types 1, 2, and 3) used by injection; has largely been replaced by the oral vaccine. See: Salk vaccine. (05 Mar 2000) |
| abortion, multiple | Couples who have had 2 or more miscarriages (spontaneous abortions) have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
| advanced multiple-beam equalization radiography | A variant of scanning equalization radiography using several X-ray beams. (05 Mar 2000) |
| amyloidosis of multiple myeloma | Foci of amyloidosis in mesenchymal tissues of some persons with multiple myeloma; no direct relation between amyloid and Bence Jones protein is conclusively known. (05 Mar 2000) |
| cancer, multiple myeloma | A bone marrow cancer involving a type of white blood cell called a plasma (or myeloma) cell. The tumour cells can form a single collection (a plasmacytoma) or many tumours (multiple myeloma). Plasma cells are part of the immune system and make antibodies. Because patients have an excess of identical plasma cells, they have too much of one type of antibody. As myeloma cells increase in number, they damage and weaken the bones, causing pain and often fractures. When bones are damaged, calcium is released into the blood leading to hypercalcaemia (excess calcium in the blood) and that causes loss of appetite, nausea, thirst, fatigue, muscle weakness, restlessness, and confusion. Myeloma cells prevent the bone marrow from forming normal plasma cells and other white blood cells important to the immune system so patients may not be able to fight infections. The cancer cells can also prevent the growth of new red blood cells, causing anaemia. Excess antibody proteins and calcium may prevent the kidneys from filtering and cleaning the blood properly Cancer, non-Hodgkin's lymphoma: A lymphoma is a cancer that develops in the lymphatic system. The most common symptom of non-Hodgkin's lymphomas is a painless swelling in the lymph nodes in the neck, underarm, or groin. Non-Hodgkin's lymphomas are diagnosed with a biopsy of an enlarged lymph node. Follow-up examinations are important after lymphoma treatment. Most relapses occur in the first 2 years after therapy.

| chromosomes in multiple miscarriages | Couples who have had more than one miscarriage (spontaneous abortion) have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
| miscarriages, multiple, chromosomes in | Couples who have had more than one miscarriage have about a 5% chance that one member of the couple is carrying a chromsome translocation responsible for the miscarriages. (12 Dec 1998) |
| multiple | Manifold, occurring in or affecting various parts of the body at once. Origin: L. Multiplex (18 Nov 1997) |
| multiple alcohol | An alcohol containing more than one OH group. (05 Mar 2000) |
