HIV seropositivity of needles from shooting galleries in south Florida.

Needle/syringe combinations were collected from three shooting galleries in South Florida and tested for the presence of antibodies to HIV-1. Fifteen of 148 needles (10.1 percent) tested positive for HIV-1 antibody. Seropositivity rates did not vary by the day of the week of collection, nor by shooting gallery from which they were collected. When the needle appeared to contain blood residue, 20.0 percent were positive versus 5.1 percent with no blood residue. These findings suggest that needles/syringes used in shooting galleries are likely to serve as reservoirs and/or vectors of transmission of the HIV-1 virus, and that although visual inspection of the needle/syringe may be useful in lessening the chance for transmission, even the visually "clean" needles may result in transmission of infection.

An analysis of the accessibility and nonaccessibility of patients in a follow-up study.

In a follow-up study of 184 emergency room patients experiencing acute drug reactions, several respondents were inaccessible. In this paper the 83 accessible and 101 nonaccessible patients are compared in order to determine why respondents are often difficult to locate in a follow-up study. Those patients who were the most accessible proved to be primarily young, White males who had been referred to a traditional drug treatment program from the hospital emergency room. Those patients who were the least accessible proved to be primarily White females between 24 and 29 years of age who had not been referred for further treatment.

Comprehensive drug programs: the Dade County example.

The authors present data from a survey of four methadone maintenance programs, five outpatient clinics, six nonresidential facilities, and nine therapeutic communities affiliated with the Dade County Comprehensive Drug Program. The treatment population included more blacks but fewer Latins than the general county population. Primary drugs of abuse were narcotics in methadone clinics and "softer" drugs in outpatient and nonresidential facilities. Most patients were either self- or court referrals. Direct per patient costs, which were lowest in the outpatient clinics, averaged $1,041. The authors suggest that their data may aid other comprehensive drug treatment programs in establishing guidelines.

Crack use and correlates of use in a national population of street heroin users. The National AIDS Research Consortium.

Traditionally, researchers and clinicians have viewed street heroin users as representing an end point in a drug-using career. It is toward this population that major national treatment efforts have been directed. Concomitant with the historical national concern about heroin use has been concern about the increase in crack cocaine use. There has been speculation that crack use may have become a substitute for the higher risk of heroin injection. This article examines the impact of crack use in a national population of heroin users. It was consistently found that there was a correlation between the frequency of crack use and the frequency of speedballing as well as the use of other forms of cocaine, amphetamines, and marijuana. There was also a positive relationship between frequency of crack use and such HIV risk behaviors as renting needles and having a large number of sex partners. The data suggest that in this population of heroin users, crack is not a substitute for heroin but rather is a part of a drug-use pattern that includes an increased use of other drugs and increased high-risk behaviors for contracting HIV.
