| brisket disease | A disease of cattle, characterised by edematous swelling of the brisket and the tissues of the neck; the body cavities also contain large quantities of clear straw-coloured transudate; this disease results from right heart failure as a consequence of increased pulmonary resistance, which is in some way associated with movement of animals to high altitudes. Synonym: mountain sickness. (05 Mar 2000) |

| Brissaud's disease | <clinical sign> An involuntary compulsive, repetitive, stereotyped movement, resembling a purposeful movement because it is coordinated and involves muscles in their normal synergistic relationships, tics usually involve the face and shoulders. (18 Nov 1997) |
| broad beta disease | Hyperlipoproteinaemia characterised by increased plasma levels of LDL, beta-lipoproteins, pre-beta-lipoproteins, cholesterol, phospholipids, and triglycerides; hypertriglyceridemia induced by a high carbohydrate diet, and glucose tolerance is abnormal; frequent eruptive xanthomas and atheromatosis, particularly coronary artery disease; biochemical defect lies in apolipoproteins; there are many varieties. Synonym: carbohydrate-induced hyperlipaemia, dysbetalipoproteinaemia, familial hyperbetalipoproteinaemia and hyperprebetalipoproteinaemia, familial hypercholesterolaemia with hyperlipaemia.

| Brodie's disease | Chronic hypertrophic synovitis of the knee. Synonym: Brodie's disease. (05 Mar 2000) |
| bronzed disease | A genetic disease in which the body takes in too much iron from food, this causes excess iron to be deposited in the liver and heart and other organs, eventually leading to organ failure and death. This illness is called bronze diabetes because the kidneys often fail, leading to symptoms similar to those found with diabetes mellitus, and because the deposition of iron into the skin makes the person look like he or she has an all-over tan. It used to be believed that this disease was rare and mainly affected people of Caucasian descent, butin recent years scientists have realised it is more common and affects a wide range of ethnic groups. Some believe that this genetic defect actually helps people (especially women) survive in areas where malnutrition is widespread and iron is scarce in food. Regular venesection may help people suffering from this disease. (09 Oct 1997) |

| Bruton's disease | <disease, immunology> An inherited disease due to agammaglobulinaemia caused by a deficiency in B lymphocyte function. Inheritance: sex-linked recessive. (18 Nov 1997) |
| Buerger's disease | <cardiology> A progressive occlusive disease of the arteries and veins. The cause of Buerger's disease is unknown. Smoking appears to accelerate the occlusive effects of Buerger's. (27 Sep 1997) |

| Bury's disease | A chronic symmetrical eruption of flattened nodules, of a pinkish or purplish colour, occurring in plaques on the buttocks and extensors of wrists, elbows, and knees, becoming fibrotic and finally scarring; early lesions show necrotizing vasculitis with fibrinoid or lipid deposits in vessel walls. Synonym: Bury's disease. (05 Mar 2000) |
| Buschke's disease | A diffuse, non-pitting induration of the skin of unknown aetiology that occurs most commonly in association with diabetes mellitus, predominantly in females. It typically begins on the face or head and spreads to other areas of the body, sometimes involving noncutaneous tissues. Often it is preceded by any of various infections, notably staphylococcal infections. The condition resolves spontaneously, usually within two years of onset. (12 Dec 1998) |
