Crack cocaine use in a cohort of methadone maintenance patients.
We examined crack use in a cohort of methadone patients originally enrolled in 1984-86. Crack use questions were added to the study in 1987. Of the 494 methadone patients originally enrolled, 228 subjects remained in methadone and were re-interviewed in 1987-88, and 234 remained in methadone and were re-interviewed in 1988-89. Approximately one-quarter of the subjects were using crack at each of the 1987-88 and 1988-89 data collection points, and only 3% of the subjects were using crack at daily or greater frequencies at each of the 1987-88 and 1988-89 interviews. Concurrent crack use was associated with (a) the number of noninjected drugs being used; (b) the number of IV drug-using sexual partners; (c) drug injection; and (d) the use of nonheroin opiates. Persistent crack use, defined as use in both 1987-88 and 1988-89, was associated with previous noninjected drug use and previous suicide attempts. While the potential problem of crack use among methadone patients should not be minimized, it appears that, compared to illicit drug injectors not in treatment, being in methadone maintenance may offer a protective effect against crack use.
Implications of the revised surveillance definition: AIDS among New York City drug users.
The Centers for Disease Control (CDC) has proposed revising the AIDS surveillance definition to include any HIV-seropositive person with a CD4 cell count of less than 200 cells per microliter. Based on a study of persons receiving treatment for HIV infection, this new definition would lead to an estimated 50% increase in the number of persons recognized as living with AIDS. Among 440 HIV-seropositive research subjects recruited from drug treatment programs and through street outreach in New York City, 59 met this definition, yet only 25% of those had been reported to the New York City AIDS registry. The new definition, if combined with HIV and T-cell testing at drug treatment and street outreach programs, could thus yield very large increases in the number of injecting drug users meeting the new surveillance definition of AIDS.
Treatment retention of patients referred by public assistance to an alcoholism clinic.
In order to ascertain the relative impact of coercion by a welfare program on retention in an ambulatory alcoholism program, records of 178 consecutive admissions to an inner-city alcoholism clinic were reviewed. Patients who came to the clinic via coerced referral from a public assistance agency were as likely to remain in treatment for at least nine sessions as self-referred patients.
HIV-1 infection among intravenous drug users in Manhattan, New York City, from 1977 through 1987.
Intravenous drug users are the second largest group to develop the acquired immunodeficiency syndrome, and they are the primary source for heterosexual and perinatal transmission in the United States and Europe. Understanding long-term trends in the spread of human immunodeficiency virus among intravenous drug users is critical to controlling the acquired immunodeficiency syndrome epidemic. Acquired immunodeficiency syndrome surveillance data and seroprevalence studies of drug treatment program entrants are used to trace seroprevalence trends among intravenous drug users in the borough of Manhattan. The virus entered this drug-using group during the mid-1970s and spread rapidly in 1979 through 1983. From 1984 through 1987, the seroprevalence rate stabilized between 55% and 60%--well below hepatitis B seroprevalence rates. This relatively constant rate is attributed to new infections, new seronegative persons beginning drug injection, seropositive persons leaving drug injection, and increasing conscious risk reduction.
A larger spectrum of severe HIV-1--related disease in intravenous drug users in New York City.
Increasing mortality in intravenous (IV) drug users not reported to surveillance as acquired immunodeficiency syndrome (AIDS) has occurred in New York City coincident with the AIDS epidemic. From 1981 to 1986, narcotics-related deaths increased on average 32% per year from 492 in 1981 to 1996 in 1986. This increase included deaths from AIDS increasing from 0 to 905 and deaths from other causes, many of which were infectious diseases, increasing from 492 to 1091. Investigations of these deaths suggest a causal association with human immunodeficiency virus (HIV) infection. These deaths may represent a spectrum of HIV-related disease that has not been identified through AIDS surveillance and has resulted in a large underestimation of the impact of AIDS on IV drug users and blacks and Hispanics.
The AIDS epidemic among blacks and Hispanics.
Social researchers and epidemiologists, as well as their major institutions and the general public, have been slow to address the racial and ethnic aspects of the AIDS epidemic. Whether measured by categories associated with major routes of infection, age level, gender, or by diminished length of survival, blacks and Hispanics are disproportionately affected by AIDS. Education, care, and outreach efforts based upon stereotypes of gay white males will have to yield to greater attention to cultural differences--and potential strengths--within each of the special "communities at risk." Evidence indicates areas of social resistance along with unique possibilities for change.

A controlled assessment of propranolol in the treatment of neuroleptic-induced akathisia.
Twelve patients with neuroleptic-induced akathisia were treated in a randomised, double-blind, cross-over design with propranolol and matching placebo. Propranolol caused significant decrements in both subjective and objective ratings of akathisia, but not in anxiety scores. This confirms prior findings of the efficacy of propranolol in akathisia induced by neuroleptic treatment.
