ABSTRACT

This study examines patterns of injecting drug use and hepatitis C (HCV) risk behavior among injecting drug users. A survey of injecting drug users attending needle and syringe programs (NSPs) in the Sydney metropolitan area and members of NSW Users and AIDS Association (NUAA) yielded 336 responses. Demographic, behavioral and drug-use information was collected from injecting drug users aged from 14 to 64 years. The majority of respondents (66%) were HCV positive, 28% had tested negative and 5% did not know their status. Prevalence was higher among men than among women (54% vs 44%). Two thirds of respondents (72%) reported frequent heroin injection. Multivariate analysis identified the following significant risk factors for hepatitis C: being more than 30 years of age, an injecting history of five years or more, and having shared drug injecting equipment with a HCV positive user. The most significant factor associated with needle sharing was having unprotected sex with sexual partners and having a positive hepatitis C test result. Early identification of these factors should be a component of HCV prevention programs. Our data indicate that the promotion of safer injecting continues to be an important public health issue with regard to reducing HCV infections.

ABSTRACT

Cysticercosis, once rare in Australia, is now more frequently diagnosed. This change reflects the countries of origin of new immigrants and the destinations of Australians travelling. Five cases of neurocysticercosis diagnosed at Westmead Hospital in Sydney are described. Two involved Australians, a father and son who had visited eastern and southeastern Asia 10 years before presentation. The other three included immigrants from Chile and India and a visitor from Timor. Ages ranged from 5 to 57 years. Three individuals presented after focal seizures involving the upper limb, one had a long standing history of neurological dysfunction and one suffered from persistent headaches. In all cases computed tomographic scanning (CT) or magnetic resonance imaging (MRI) revealed cystic brain lesions and three of the five were seropositive as well. Four were treated with praziquantel and in one the lesions regressed significantly following treatment. However, the lesion in one case had decreased in size prior to treatment and that in the untreated individual also became smaller.
