| Ayerza's disease | <syndrome> Sclerosis of the pulmonary arteries in chronic cor pulmonale; associated with severe cyanosis, it is a condition resembling polycythemia vera but resulting from primary pulmonary arteriosclerosis or primary pulmonary hypertension and characterised by plexiform lesions of arterioles.

| Azorean disease | A rare form of hereditary ataxia, characterised by onset in early adult life of progressive, spinocerebellar and extrapyramidal disease with external ophthalmoplegia, rigidity dystonia symptoms, and, often, peripheral amyotrophy; found predominantly in people of Azorean ancestry; autosomal dominant inheritance. Synonym: Azorean disease, Portuguese-Azorean disease. Origin: Surnames of two families studied in major descriptions of the disease. (05 Mar 2000) |

| Baelz' disease | An acquired disorder, of unknown aetiology, of the lower lip characterised by swelling, ulceration, crusting, mucous gland hyperplasia, abscesses, and sinus tracts. Synonym: Baelz' disease, myxadenitis labialis, Volkmann's cheilitis. (05 Mar 2000) |
| Balo's disease | Encephalitis that is clinically similar to adrenoleukodystrophy, but pathologically characterised by concentric globes or circles of demyelination of cerebral white matter separated by normal tissue. Synonym: Balo's disease. (05 Mar 2000) |
| Baltic myoclonus disease | One of the familial light sensitive myoclonic epilepsies. Unlike Lafora body polymyoclonus, where inclusion bodies are seen in the brain cells, the prognosis is often favourable. Probably an autosomal recessive disorder. (05 Mar 2000) |

| Bamberger's disease | A spasmodic affection of the muscles of the lower extremities. Synonym: Bamberger's disease, dancing spasm, Gowers disease. (05 Mar 2000) |
| Bang's disease | A disease in cattle caused by Brucella abortus; in pregnant cows, characterised by abortion late in pregnancy, followed by retained placenta and metritis; in bulls, orchitis and epididymitis may occur; the organism may localise in the udder and thus appear in milk from infected cows. Synonym: Bang's disease. (05 Mar 2000) |
| Bannister's disease | A vascular reaction involving the deep dermis or subcutaneous or submucal tissues, representing localised oedema caused by dilatation and increased permeability of the capillaries and characterised by development of giant wheals. (18 Nov 1997) |
| Banti's disease | <syndrome> Chronic congestive splenomegaly that occurs primarily in children as a sequel to hypertension in the portal or splenic veins, usually as a result of thrombosis of the veins; anaemia, splenomegaly, and irregular episodes of gastrointestinal bleeding are usually observed, with ascites, jaundice, leukopenia, and thrombocytopenia developing in various conbinations. Synonym: Banti's disease, splenic anaemia. (05 Mar 2000) |

Synonym: Barraquer's disease, lipodystrophia progessiva superior, partial lipoatrophy, Simons' disease. (05 Mar 2000) |
| bartter's disease | Hypertrophy and hyperplasia of the juxtaglomerular cells, producing hypokalaemic alkalosis and hyperaldosteronism, characterised by absence of hypertension in the presence of markedly increased plasma renin concentrations, and by insensitivity to the pressor effects of angiotensin. It usually affects children, is perhaps hereditary, and may be associated with other anomalies, such as mental retardation and short stature. It is also called juxtaglomerular cell aplasia.
