Abstract
This article presents a new instrument with which to assess the effects of opiate treatment. The Opiate Treatment Index (OTI) is multi-dimensional in structure, with scales measuring six independently measured outcome domains: drug use; HIV risk-taking behaviour; social functioning; criminality; health; and psychological adjustment. Psychometric properties of the Index are excellent, suggesting that the OTI is a relatively quick, efficient means of obtaining reliable and valid data on opiate users undergoing treatment over a range of relevant outcome domains.

Abstract
Restricting availability is the major response to illicit drugs in most Western countries including Australia. Prohibition may reduce harm when the drug in question is in low demand, controls are difficult to subvert, and when similar drugs are less toxic or unavailable. However, the health, social and economic costs of supply reduction are substantial and increasing for both injecting drug users and the general community. Population adjusted mortality of heroin users has doubled in Australia in the last decade. The possible impact of supply reduction policy on the spread of HIV infection among IDUs is an important but largely neglected consideration. The effectiveness of supply restriction policy in decreasing the availability of drugs or in reducing drug-related harm is unlikely to be increased significantly by more vigorous implementation of supply reduction or adoption of new technology. Conversely, on the basis of existing data, greater availability of HIV prevention measures attractive to the target population (including especially drug treatment such as methadone maintenance) is likely to be effective and cost-effective. The costs and benefits of innovative methods of providing currently illicit drugs to those who are determined to use them requires careful evaluation and comparison with existing policies. Policy on illicit drugs in most countries including Australia is still dominated by concern about drug use rather than focused on the need to reduce drug-related problems which is the agreed aim of national drug policy.

Abstract
Injecting drug users (IDUs) play a disproportionate role in the spread of HIV given their injecting and sexual contacts, and thereby act as conduits between these risk groups. We investigated differences in risk behaviour and HIV seroprevalence in a Sydney sample of 1,245 IDUs. Significant differences were observed across sexual orientation in HIV serostatus for males, with homosexual men having the highest HIV seroprevalence rate (35%), bisexual men intermediate (12%) and heterosexual men lowest (3%). Sexual HIV risk behaviours were lowest for homosexual men, intermediate for bisexual men, and highest for heterosexual men in the case of condom use: however, for numbers of partners, seroprevalence, and anal sex the trends were reversed. There were no differences across sexual orientation for either sex for injecting drug risk behaviours. Both male and female respondents reported having more than 50% of sexual contacts while under the influence of drugs. This study suggests that risk reduction in the sexual domain has not generalized to the injecting risk domain regardless of sexual orientation, and demonstrates that sexual risk behaviours in IDUs are lowest in homosexual, intermediate in bisexual, and highest in heterosexual IDU men.

Abstract
Current drug use and HIV risk-taking behaviour of a sample of 95 methadone maintenance clients was investigated. Subjects had been on their current programme for an average of 70.9 weeks with a mean daily dose of methadone of 65.6 mg. Two-thirds had injected heroin, and 82% had injected a street drug in the month prior to interview. Over 20% of subjects had shared a needle in the month before interview, all with only one other person. Subjects who had injected cocaine in the month before interview had significantly higher levels of injecting risk-taking behaviour than those subjects who had injected but not used cocaine. Condom use among subjects was low, particularly in regular relationships. While knowledge concerning HIV was high among subjects, there was no relation between level of knowledge and actual behaviour. It is concluded that knowledge alone is not sufficient to ensure behaviour change.

Abstract
Dimensions of HIV infection risks were investigated in 1,245 injecting drug users (IDUs) in Sydney, Australia. Factor analysis of the degree of risk of the 33 items of risk behaviours revealed ten dimensions, which covered the domains of oral sex, withdrawal before ejaculation, protected intercourse, unprotected vaginal intercourse, saliva, blood products, manual sex, needles and syringes, unprotected anal sex, and social transmission. The perceived riskiness of particular activities closely approximated the objectively assessed risk of particular practices. Women assessed the risks of classes of activities (with the exception of oral sex) as being higher than did men. IDUs appear to have readily interpretable and consistent perceptions of HIV transmission risks, and these dimensions have utility for measuring perception and knowledge of HIV transmission risks.

Abstract
The efficient and accurate measurement of recent drug use is an essential component of treatment and research among opioid users. Urinalysis results alone will not give sufficient information to either the clinician or researcher, due to limitations in detection and an inability to distinguish extent of use. The present paper describes a 'recent use episodes method', adapted from the measurement of alcohol consumption, for obtaining self-reported drug use in eleven different drug categories. Reliability and validity data indicate that the method provides a quick means by which accurate information may be obtained on the overall recent drug use of opioid users.

Abstract
The initiation and maintenance of substantial behaviour change is required to reduce the spread of HIV infection among the intravenous drug-using population. In order to ascertain the efficacy of interventions aimed at reducing HIV-related risk-taking behaviour among this population, valid and reliable (yet preferably short) instruments for measuring such behaviour are required. The HIV risk-taking behaviour scale (HRBS) is a brief 11-item interviewer-administered scale which examines the behaviour of intravenous drug users in relation to both injecting and sexual behaviour. This paper describes the construction of the scale, in addition to data evaluating its reliability and validity. Initial analyses indicate that the scale has satisfactory psychometric properties.

Abstract
Self-reported histories of sexually transmissible diseases (STDs) and HIV serostatus were investigated as part of a study of HIV risk behaviour in a sample of 1245 Syndey injecting drug users (IDUs) (mean age 27.5 years) both in and out of treatment. A high lifetime prevalence of STDs was reported in both men and women. For male IDUs, the lowest reported lifetime prevalence of STDs was in heterosexuals, with bisexuals intermediate and homosexuals reporting the highest prevalence. HIV seroprevalence followed the same pattern. For women, bisexuals had the highest reported STD history, heterosexual women were intermediate and homosexual women reported the lowest prevalence. Over one third of the bisexual women reported having been involved in prostitution. These data indicate that over one third of IDU men and over half of IDU women reported at least one STD in their lifetime. The high lifetime prevalence of STDs in IDUs indicates that this group is at increased risk of sexual transmission of HIV, given the importance of STDs as a cofactor. Reducing the prevalence of STDs in IDUs is a possible additional strategy to diminish the spread of HIV among IDUs and from them to non-IDU sexual contacts.

Abstract
In November 1986, a pilot needle and syringe exchange was established in Sydney adjacent to a methadone maintenance unit. A retrospective study was carried out to determine the effect of increasing the availability of sterile needles and syringes on the treatment outcome of the methadone maintenance unit. In this study, an increase in availability of sterile needles and syringes was not found to be associated with an increase in the presence of illicit injectable drugs in the urine specimens of clients of the methadone programme compared to a control methadone unit where there was no known change in needle and syringe availability. This study suggests that an increase in the availability of sterile needles and syringes does not appear to lead to an increase in the frequency of intravenous drug use. The possibility of drug and alcohol treatment centres acting as needle and syringe exchange or distribution outlets therefore requires consideration.

Abstract
It illustrates an approach to "at risk" youth which implicates the age group in planning and application, in an area where they are involved. It is a communication and health initiative which has achieved a good measure of success in Australia with the rock'n roll music sub culture. It reaches out not only in the drugs area but also in the area of AIDS.

Abstract
This study was carried out in 1987 to investigate the relationships between human immunodeficiency virus (HIV)-related risk-taking behaviour, demographic characteristics and serostatus of 181 intravenous drug users in Sydney. Subjects were predominantly heterosexual men in their late twenties with limited secondary education. The majority (77%) had been injecting drugs for more than two years and were daily (91%) injectors of heroin (87%). Eighty per cent had shared injection equipment. Condom use was uncommon (15%) except during prostitution (72%). Sixty-nine per cent of all subjects were at risk of HIV infection due to either unsafe sexual practices or sharing of injection equipment. Thirty per cent of the sample had been in prison at some time since 1981 and half of these (15%) had used intravenous drugs and shared injection equipment while in custody. Thirteen per cent of men who had been imprisoned reported anal intercourse with other male prisoners. HIV antibody test results were available from 132 subjects of whom 12 (9%) (95% confidence intervals [CI], 4%-14%) were seropositive. The majority (67%) of seropositive subjects were homosexual/bisexual men but no other behavioural or demographic factor differentiated seropositive from seronegative subjects. The HIV seroprevalence (9%) found in this study of intravenous drug users in Sydney is significantly higher than a 1985 estimate of 0.5% (P less than 0.001). This finding and the level of risk-taking behaviour by this sample indicates that strategies introduced at the time may have been inadequate to prevent HIV infection among intravenous drug users in Sydney. Widespread HIV infection in Australian intravenous drug users may be imminent unless major changes in HIV-related risk-taking behaviour occur in the near future.

Abstract
Gastrointestinal disease in AIDS is common and is due to opportunistic infections, aggressive malignancy and possible direct HIV enteropathy. Disabling gastrointestinal symptoms are prominent both in patients with established AIDS and in patients with earlier stages of HIV infection. We report the cases of 160 patients with AIDS who underwent gastroenterological investigations at St Vincent's Hospital, Sydney, between November 1983 to October 1987. Of these, 127 had the diagnosis of AIDS established prior to referral and 33 patients had the diagnosis of AIDS established as a result of gastroenterological investigations. Diarrhoea and weight loss (88%) were the most frequent reasons for undertaking gastroenterological investigations. Swallowing disorders (47%), abdominal pain (20%), oral and perianal disease (74%) and evidence of hepatobiliary disease were the other major indications for investigation. In 90% of cases there was evidence of concurrent and active gastrointestinal disease at two or more sites within the alimentary tract. Results from this series reveal a wide range of infectious pathogens: viral (Cytomegalovirus, Herpes simplex), bacterial (Mycobacterium avium intracellulare) and parasitic (Cryptosporidium, Isospora belli). Kaposi's sarcoma and non-Hodgkin's lymphoma were the only malignancies detected in this series. Gastrointestinal disease associated with HIV infection is common, and contributes significantly to its overall morbidity and mortality. Moreover, chronic diarrhoea, weight loss and malnutrition may also contribute to the overall immunodeficiency.
