925 infection in AIDS patients. MAC is believed to be a major cause of the wasting syndrome that affects many AIDS patients. Criteria for eligibility for rifabutin under the Treatment IND (investigational new drug) protocol are a diagnosis of AIDS as defined by the US Centers for Disease Control, no history of MAC infection, and a CD4 cell count of200/u.l or less. Rifabutin is the 26th drug to receive Treatment IND status since this programme was introduced in 1987. It was granted this status on the basis of two large controlled clinical studies indicating that it may be effective in preventing or delaying MAC infection in patients with impaired immune systems. There is no evidence from these clinical studies that the drug reduces or delays mortality. The most serious adverse effect of rifabutin seems to be marrow depression. Other common side- effects include influenza-like symptoms, gastrointestinal disorders, and rash. Food for thought For those readers who have carnivorous inclinations, the latest World Health Organisation (WHO) technical report on veterinary drug residues in food! makes dyspeptic reading. Toxicological and safety data about ten drugs used in animal medications or as aids to animal production are reviewed. They include carazolol (a &bgr;-blocker given to prevent stress-induced sudden death in pigs), anthe1mintics, antimicrobials, and tranquillisers. Drugs given immediately before slaughter may lead to adverse effects among consumers-eg, carazolol in asthmatics. The report recommends both acceptable daily intakes and maximum residue levels for six of the ten drugs under review; insufficient data are available for advice about tranquillisers and tylosin, a macrolide antibiotic. The need for further toxicological studies (eg, on teratogenicity) is also outlined. Attention to improvements in pre-slaughter animal handling should diminish the need for drug treatment. Illicit drug administration to animals was not covered in the report, although this can produce important clinical sequelae .1,3 WHO plans to convene the committee annually and it is to be hoped that non-veterinary drugs given to increase muscle growth and weight gain will be included in their future deliberations.

More about tobacco control The worldwide fight against tobacco gained impetus last month with the Australian Government’s announcement of a ban on tobacco advertising and all forms of promotion, including sponsorship of sports.

The Australian authorities’ decision is welcome, but it carries several caveats-sponsorship for cricket is excluded from the ban until the end of 1995/96 season, and there are exemptions for internationally televised events held in Australia that would be in jeopardy if immediately covered by the ban.
