* Body piercing where rings and studs are put into the ear, tongue, navel or genitalia can cause infections in up to 25 per cent of cases, a report has discovered. The practice has also been blamed for transmitting TB, hepatitis B and C, and even HIV (Clin Infect Dis, 1998; 26: 735-40).
* Chocolate is often blamed for migraines, but perhaps we should look elsewhere. Sixty three women who suffer headaches were given 60 g of chocolate or of carob (a caffeine free chocolate substitute). Just 17 per cent of those who had chocolate reported a headache afterwards, compared with 40 per cent of those who had carob (Cephalalgia, 1997; 17: 855-62).
* The US Food and Drug Administration is debating whether to approve a dieting drug that may increase breast cancer risk. Nine cases were detected in a group of 4000 women testing the drug, Orlistat (Lancet, 1988; 351: 885).
