Kawasaki disease may be rare, but it's now the commonest cause of acquired heart disease in children under 5. It's an acute, self limiting, multiorgan vasculitis of unknown cause. The problem is the vasculitis tends to affect coronary arteries and can cause sudden death if untreated. Immunoglobulins and aspirin reduce cardiac complications significantly.Diagnosis is essentially clinical-fever for five days and at least 4 of the following: * Red eyes (bilateral conjunctivitis, no pus) * Sore red mouth, * red cracked lips, and * classically a "strawberry" tongue with protuberant papillae * Polymorphous maculopapular skin rash * Cervical lymphadenopathy, usually unilateral and >1.5 cm in diameter * Erythema and oedema of the hands and feet (with desquamation of the skin in the later stage of the illness).

Source: BMJ 2009;338:b1668 New NICE guidelines in the UK on newer drugs for use in diabetes are summarised in the BMJ. Some key points are: Add sitagliptin (a DPP-4 inhibitor) as second line treatment with metformin instead of a sulphonylurea when blood glucose control is inadequate if sulphonylureas are contraindicated or if the patient is at risk of hypoglycaemia Add sitagliptin or a thiazolidinedione (pioglitazone or rosiglitazone) as a third line treatment if metformin and a sulphonylurea are not adequately controlling blood glucose and insulin is unsuitable Don't use thiazolidinediones in patients with heart failure or at high risk of fracture Add pioglitazone to insulin therapy if a thiazolidinedione has lowered blood glucose in the past or if high dose insulin is not adequately controlling blood glucose.
