| Beckwith-Wiedemann syndrome | <syndrome> This syndrome, of unknown cause, is characterised by a group of the following findings: large tongue, organ enlargement (visceromegaly), large body size, umbilical hernia and neonatal hypoglycaemia. Evidence suggests a genetic lesion. Birth weight is often more than 8 pounds. Complications include Wilm's tumour, seizures, aspiration and hypoglycaemia. (27 Sep 1997) |

| Behcet's syndrome | <syndrome> A multisystem, chronic recurrent disease characterised by ulceration in the mouth and genitalia, iritis, uveitis, arthritis and thrombophlebitis. Often treated with immunosuppressive therapy (corticosteroids, chlorambucil). (27 Sep 1997) |
| Behr's syndrome | <syndrome> Adult or presenile form of heredomacular degeneration. Synonym: Behr's disease. (05 Mar 2000) |
| Benedikt's syndrome | <syndrome> Hemiplegia with clonic spasm or tremor and oculomotor paralysis on the opposite side. (05 Mar 2000) |
| Beradinelli's syndrome | <syndrome> The clinical findings of accelerated growth, lipodystrophy with muscular hypertrophy, hepatomegaly and lipaemia. (27 Sep 1997) |
| Bernard-Horner syndrome | <syndrome> A nerve condition which involves a dropping eyelid (ptosis), constricted pupil, enophthalmos and lack of sweating on one side of the face. Often seen in association with injury (for example neck fracture, penetrating injury) to the cervical sympathetic nerve trunk in the neck or a Pancoast tumour involving both the upper and lower brachial plexus. (29 Sep 1997) |
| Bernard-Sergent syndrome | Severe adrenocortical insufficiency when an intercurrent illness or trauma causes an increased demand for adrenocortical hormones in a patient with adrenal insufficiency due to disease or use of relatively large amounts of similar hormones as therapy; characterised by nausea, vomiting, hypotension, and frequently hyperthemia, hyponatraemia, hyperkalaemia, and hypoglycaemia; can be fatal if untreated. Synonym: addisonian crisis, adrenal crisis, Bernard-Sergent syndrome. (05 Mar 2000) |
| Bernard Soulier syndrome | <haematology, syndrome> A congenital disorder where the platelets lack receptors which allow them to adhere to the walls of blood vessels. The genetic deficiency in platelet membrane glycoprotein Ib allows platelets to aggregate normally (c.f. Glanzmann's thrombasthenia) but they do not stick to collagen of sub endothelial basement membrane. The net result is a platelet function disorder that causes a prolonged bleeding time. Symptoms include nosebleeds, easy bruising, heavy menstrual periods, bleeding gums and increased post-operative bleeding. Avoidance of aspirin, anti-inflammatories or any other agents which can cause bleeding is critical. (06 Oct 1997) |
| bernard syndrome | <syndrome> A complex of abnormal findings, namely sinking in of one eyeball, ipsilateral ptosis (drooping of the upper eyelid on the same side) and miosis (constriction of the pupil of that eye) together with anhidosis (lack of sweating) and flushing of the affected side of the face. Due to paralysis of certain nerves (specifically, the cervical sympathetic nerves). Also called Horner-Bernard syndrome, Bernard-Horner syndrome and Horner's ptosis, but best known today as Horner syndrome. (12 Dec 1998) |
| Bernhardt-Roth syndrome | <symptom> A tingling, formication, itching, and other forms of paresthesia in the outer side of the lower part of the thigh in the area of distribution of the lateral femoral cutaneous nerve; there may be pain, but the skin is usually hypesthetic to the touch. Synonym: Bernhardt's disease, Bernhardt-Roth syndrome, Roth's disease, Roth-Bernhardt disease. (21 Sep 2000) |
| Bernheim's syndrome | <syndrome> Systemic congestion resembling the consequences of right heart failure (enlarged liver, distended neck veins, and oedema) without pulmonary congestion in subjects with left ventricular enlargement from any cause. A reduction in the size of the right ventricular cavity is found by contrast imaging or echocardiography or at postmortem due to encroachment by the hypertrophied or aneurysmal ventricular septum. (14 Aug 2000) |
| Besnier-Boeck-Schaumann syndrome | <disease> Disease of unknown aetiology in which there are chronic inflammatory granulomatous lesions in lymph nodes and other organs. (18 Nov 1997) |
| Beuren syndrome | <syndrome> Supravalvular aortic stenosis with multiple areas of peripheral pulmonary arterial stenosis, mental retardation, and dental anomalies. (05 Mar 2000) |
| Biemond syndrome | <syndrome> Iris coloboma, mental retardation, obesity, hypogenitalism, and postaxial polydactyly; a recessive inheritance disorder resembling Laurence-Moon and Bardet-Biedel syndrome's. (05 Mar 2000) |
| billowing mitral valve syndrome | <syndrome> The clinical constellation of findings with or without symptoms due to prolapse of the mitral valve: a nonejection systolic click accentuated in the standing posture, sometimes multiple, sometimes with mitral regurgitation occurring relatively late in systole, and accompanied by echocardiographic evidence of the mitral valve prolapse, usually with thickened leaflets of the valve. Symptoms are non-specific and may include vague chest pains and dyspnea on exertion. Synonym: billowing mitral valve syndrome. (05 Mar 2000) |
