[Clinical wound botulism in injecting drug addicts].

Wound botulism among drug abusers was first described in the USA in 1982. From 1988 to 1995, 46 laboratory confirmed cases were reported in California. The condition occurred for the first time in Norway in 1997 when three cases of suspected wound botulism among drug users who injected heroin subcutaneously or intramuscularly were reported. Two of these cases are presented here with neurophysiological findings and differential diagnosis.
