Adolescent drug using groups in Chicago parks.

In a northern Chicago neighborhood, observational and interview data were collected at parks, school lots, and beaches where adolescents congregate to buy, sell, and use nonopiate drugs. These sites were geographically distinct from areas where heroin is regularly distributed. Users at each area generally resided in the immediate neighborhood, were well known to one another, were predominantly male, displayed similar socioeconomic, religious and ethnic backgrounds, and had attended the same grade schools and high schools. These sites were relatively stable during the summer months, although visitors occasionally changed locations in response to police harassment. Attendance fluctuated with weather and time of day. Drug use was generally confined to the daily use of marihuana and weekend use of alcohol and sedative-hypnotics, but availability seemed to determine the type and frequency of drug use to a greater extent than drug perference. This study suggests the potential of a fieldwork model for prevention and intervention activities prior to the onset of more intense and diversified drug use.

Methadyl acetate and methadone. An open comparison.

Heroin addicts were recruited for a 14-week open clinical comparison of methadone hydrochloride and methadyl acetate. Patients were randomly assigned to a methadyl acetate clinic in which methadyl acetate was dispensed to patients three times per week or to a methadone clinic in which methadone was dispensed six days per week. No statistically significant differences were observed between groups in retention rates, illicit drug use, employment rates, or arrest rates. The group treated with methadyl acetate had more dropouts in the first seven weeks than the second seven weeks: this pattern was reversed for the methadone-treated group. The differences were significant (P = .01). Spontaneously reported symptoms suggest that induction with methadyl acetate may be a more clinically variable phenomenon than induction with methadone. The reduction of number of clinic visits in the group treated with methadyl acetate was not a source of variance in treatment effectiveness.

Withdrawal from methadone maintenance. Rate of withdrawal and expectation.

One hundred twenty-seven successfully methadone-hydrochloride-maintained patients were randomly assigned to one of the following four groups and studied for 30 weeks: (1) known maintenance-patients were maintained on methadone under open conditions; (2) blind maintenance-patients were maintained on methadone under double blind conditions; (3) rapid withdrawal-patients were withdrawn under double-blind conditions at a rate of 10% of initial dose per week; (4) gradual withdrawal-patients were withdrawn under double-blind conditions at a rate of 3% of initial dose per week. Differences in dropout rates, illicit drug use, symptoms scores, and requests for study interruption indicate that withdrawal from methadone maintenance should be carried out at approximately 3% of initial dose per week. Better patient preparation also is indicated to reduce the effects of expectation.

Height and personality characteristics of 47, XYY males in a sample of tall non-institutionalized males.

A sample of 471 enlisted men 183 cm or taller serving in the US Navy, Coast Guard, and Marine Corps was screened for Y-chromosome aneuploidy by use of quinacrine fluorescence of peripheral blood smears. Two 47,XYY males were detected, resulting in a prevalence of 00425 or approximately 1 in 236. The prevalence of 47,XYY males (00331) in a number of samples of tall, non-institutionalized males is significantly higher than the incidence in newborn males (00061), indicating that 47,XYY males are disproportionately represented in tall male populations. The 47,XYY males had significantly higher scores than 46,XY males on the Schizophrenia, Schizophrenia+1K, and Prejudice scales of the Minnesota Multiphasic Personality Inventory and significantly lower scores on the Dominance scale. Since the probability that a randomly selected pair of subjects in the sample had four or more scale scores significantly different from the remainder of the group was greater than 05, it is possible that the differences between the 47,XYY and 46,XY males occurred by chance. On the other hand, one or more of these scales may measure personality dimensions on which non-institutionalized 47,XYY males may, in fact, differ from 46,XY males.
