Malaria prophylaxis in travellers: The current position

Summary Malaria prevention is a main challenge for physicians, nurses, health officers and tour operators. The attack rate of malaria in travellers is 1–10/10,000 departures, and the case fatality rate of imported malaria is around 0.5/100. Travellers should be informed about the risk they are going to take, how to protect against mosquito bites, about the antimalarials they will have to take and about what to do when a malaria breakthrough should occur.The 4-aminoquinolines (chloroquine, amodiaquine) remain the drug of choice for the prevention ofPlasmodium vivax and of sensitiveP. falciparum infections. The problem is to find an effective and safe drug combination for travellers to areas whereP. falciparum is either resistant to chloroquine, to Fansidar (the combination of pyrimethamine plus sulfadoxine) or to both. These travellers will probably best be protected by an individually tailored drug combination, which includes amodiaquine or mefloquine as baseline drugs, and a supplementation with Fansidar, Maloprim (the combination of pyrimethamine with dapsone), paludrine or an antibiotic.     

The consequences of the discovery by W. C. Röntgen for present-day medical physics and radiation protection

When the German physicist W. C. Röntgen discovered X-rays, which were named after him, he introduced a new development in medicine and biology: together with the discoveries of A. H. Becquerel and M. Curie, radiology with its diagnostic and therapeutic methods was made possible. The medical physicist has an important task to fulfill in modern radiotherapy, nuclear medicine and radiodiagnostics. The longtime interdisciplinary collaboration has won the international recognition of medical physics as a scientific discipline, a health care profession and a university subject. Several incidents, including contemporary ones, show that the efforts made towards radiation protection must remain an important domain of the specialist.
