Israeli Christian, Druze, and Moslem adolescents' attitudes toward magazine alcohol advertisements.

This article summarizes the Christian, Druze, and Moslem part of an Israeli study which was carried out in 1988 in the framework of an international comparative project conducted simultaneously also in Australia and in the USA in order to compare the perception of a set of 64 magazine alcohol advertisements by youth from three nations and various cultural and religious groups within those nations. This study is a breakthrough in the Christian, Druze, and Moslem sectors, since it is the first project in the "alcohol domain" among high school students from those sectors. The article presents the results concerning Christian, Druze, and Moslem adolescents' attitudes toward magazine alcohol advertisements. The results have implications for prevention efforts among adolescents from those three religions.

Phase I pharmacokinetic and pharmacodynamic study of a new anthrapyrazole, CI-937 (DUP937).

We performed a phase I trial of CI-937 (DUP937), an anthrapyrazole, with the following objectives: (a) to determine the maximally tolerated dose in humans; (b) to define the toxicity spectrum of this agent; (c) to describe the pharmacokinetics of the drug; (d) to test a pharmacokinetics based hypothesis of dose escalation; and (e) to relate drug pharmacokinetics to pharmacodynamics. CI-937 was administered as a single bolus injection every 3-4 weeks at doses ranging from 3.6 to 25.2 mg/m2. Thirty-two patients and 57 courses were evaluable for toxicity. Pharmacokinetic analysis was performed in 30 patients on the first course using a sensitive and selective radioimmunoassay. The maximally tolerated dose in patients with no prior therapy was 25.2 mg/m2 and dose-limiting toxicity was neutropenia. Thrombocytopenia, nausea, vomiting, stomatitis, and alopecia were mild. A partial response was recorded in a patient with mesothelioma. The area under the curve increased linearly with dose, and total body clearance of CI-937 was independent of dose. The mean total body clearance was 107 +/- 55.8 ml/min/m2, mean steady state volume of distribution was 492 +/- 469 liters/m2, and terminal half-life was 3.78 +/- 2.86 days. The extended factors of 2 methods of pharmacologically guided dose escalation were intended for use but ultimately were equivalent to that of the modified Fibonacci dose escalation method. Dose and the area under the curve were significant predictors of a percentage change in WBC and neutrophil count in a univariate analysis. Only dose and baseline neutrophil count predicted a percentage change in WBCs in a multifactor analysis. Dose and prior chemotherapy predicted percentage change in neutrophil count in a multifactor analysis. We conclude that the dose-limiting toxicity of CI-937 is neutropenia and that the recommended phase II starting dose is 22 mg/m2.

Evidence for the effects of HIV antibody counseling and testing on risk behaviors.

OBJECTIVE: To review published abstracts, journal articles, and presentations for evidence of the effects of human immunodeficiency virus (HIV) antibody counseling and testing on risk behaviors. Studies reviewed focused on homosexual men, intravenous drug users in treatment programs, pregnant women, and other heterosexuals. DATA SOURCES: Peer-reviewed journals (January 1986 through July 1990) and published abstracts and oral presentations from the second (1986) through the sixth (1990) International Conferences on AIDS. STUDY SELECTION: We identified 66 studies that included data on the behavioral effects of HIV antibody counseling and testing. By consensus of the authors, 16 of these were excluded because of small sample size or inadequate study design. DATA EXTRACTION: Studies were assessed by the authors according to methodological strength (sample selection, inclusion of appropriate comparison groups, and inclusion of statistical tests of significance). DATA SYNTHESIS: All longitudinal studies of homosexual men reported reductions in risky behavior among both tested and untested men, and a few reported greater decreases among seropositive men than among seronegative men and those untested or unaware of their serostatus. For intravenous drug users in treatment, we found reductions in intravenous drug use and sexual risk behaviors regardless of counseling and testing experience. We found little evidence for the impact of counseling and testing on pregnancy and/or pregnancy termination rates for either seropositive or seronegative high-risk women. We noted substantial risk reduction among heterosexual couples with one infected partner. Findings among other heterosexuals at increased risk were scanty and mixed. CONCLUSIONS: Further studies should specifically address the behavioral consequences of counseling and testing in various settings.

Local toxicity with subcutaneous methadone. Experience of two centers.

We report on 8 patients treated with subcutaneous methadone for cancer-related pain at 2 institutions. The success of other subcutaneous agents for pain control has been well demonstrated. It was felt that methadone would be useful due to its low cost. Unfortunately, 7 of the 8 patients experienced adverse reactions at the subcutaneous sites requiring cessation of subcutaneous methadone.

Alcohol drinking among Moslem and Druze adolescents in Israel in 1990.

This article describes the Moslem and Druze parts of a survey conducted in the north of Israel during spring 1990 in order to investigate alcohol drinking habits of Moslem, Druze and Jewish high school students and to draw implications for prevention efforts. Of a general sample of 2763 students, 932 Moslem and 215 Druze adolescents were drawn from junior and senior high schools in a Druze village, several Moslem villages, an Arab town, and a mixed Arab-Jewish town. This is the first epidemiological study among students from those sectors in Israel. Involvement with alcohol was greatest among Druze males, lower by Moslem males from an Arab town and Moslem villages, and lowest by Moslem students in a mixed Arab-Jewish town. Druze students reported a higher rate of father's drinking than Moslem students did. Prevention efforts among these populations are discussed.

Evaluation of a spring-loaded syringe driver for the subcutaneous administration of narcotics.

A simple spring-loaded syringe driver was tested for the subcutaneous administration of narcotic analgesics and antiemetics. With concentrations of 2 to 10 mg/mL of hydromorphone and 10 to 50 mg/mL of morphine, the infusion rate during preclinical testing was 1.01 +/- 0.1 mL/hr (range 0.70-1.2 mL/hr). The rate of infusion was not modified by the concentration of narcotic in solution. Clinical trials were performed with morphine in 17 patients, and with hydromorphone in 11 patients. The duration of the infusion was 21 +/- 11 days. The most frequent reason for discontinuation was death (22 cases). The average duration of the site of infusion was 6.3 +/- 4 days. When used subcutaneously, the rate of infusion of the device was 1 +/- 0.15 mL/hr (range 0.70-1.30 mL/hr). Patients and nurses were satisfied with the simplicity and safety of the device. Cost analysis shows that this device is significantly less expensive than currently available portable infusion devices. We conclude that the Medifuse Pump is an inexpensive, safe and effective device for the subcutaneous infusion of narcotics and antiemetics.

Structure of problem behaviors in preadolescence.

Earlier research suggests that diverse adolescent problem behaviors, such as substance use, school problems, early sexual intercourse, and delinquency, reflect a single underlying dimension of behavior. Data from an ongoing longitudinal study were used to examine this issue in a previously unexamined sample (N = 426) of preadolescent sixth-grade youth. Ss included boys and girls from diverse socioeconomic and racial/ethnic backgrounds, whose average ages were 11 and 12. By using confirmatory factor analyses to test competing models, multiple factor structures were detected, suggesting that earlier findings supporting a single factor conceptualization may not be generalizable to this age group. Implications of the finding that problem behaviors may be more differentiated in late childhood than in adolescence are discussed.

Ventilatory function after exposure to various respirable hazards in a population of former coal miners.

The ventilatory function of 406 male former coal miners who had presented at the Cook County Hospital occupational medicine clinic between January 1976 and April 1987 was studied to determine whether subsequent exposure to respiratory hazards after leaving the coal mines adversely affected lung function. The miners were divided into five exposure groups based on their exposure to respirable hazards. These were coal dust only, coal dust plus asbestos dust, coal dust plus silica dust, coal dust plus another respirable hazard and coal dust plus two other respirable dust exposures. Duration of employment in coal mines, race, smoking history, and mean age were not significantly different between the various exposure groups. No significant difference was found in the per cent of predicted forced expiratory volume in one second (FEV1), per cent of predicted forced vital capacity (FVC), and FEV1/FVC when the coal dust only group was compared with each of the other four exposure groups using ANOVA. Among former coal miners who present for a respiratory disability determination, therefore, exposure to respirable hazards subsequent to employment in coal mines is not associated with a statistically significant deterioration in ventilatory function.

How American oncologists treat breast cancer: an assessment of the influence of clinical trials.

The present study was designed to assess the preferred methods of treatment of breast cancer by American oncologists, and the impact of clinical trials on their practice. We mailed 465 questionnaires to surgical, radiation, or medical oncologists. The questionnaire described five hypothetic patients with breast cancer, and respondents were asked to select their preferred treatment for each patient. For primary breast cancer, most physicians would offer the choice of local excision followed by radiation therapy or modified radical mastectomy. About 80% of physicians would prescribe adjuvant chemotherapy for a premenopausal woman with estrogen receptor-negative, axillary node negative breast cancer, and for a postmenopausal woman with estrogen receptor-negative, node-positive disease. This policy was favored by male and female physicians of each specialty. Almost all respondents would treat a young woman with inflammatory breast cancer with initial chemotherapy followed by radiation and/or surgery, and about 60% would recommend chemotherapy to a postmenopausal patient with estrogen receptor-negative disease and minimally symptomatic bone metastases. Clinical trials have compared treatment strategies that could be applied to patients described in our questionnaire. Preferred treatments for primary breast cancer, and for inflammatory breast cancer are supported by the results of clinical trials. Recommendation of adjuvant chemotherapy for node-negative breast cancer is not based on a consistent demonstration of improvement in survival, although randomized trials with short follow-up have shown delay to recurrence. Recommendation of adjuvant chemotherapy for a postmenopausal woman with node-positive breast cancer is contrary to the results of large randomized controlled trials (and to a meta-analysis), which have shown that this policy does not lead to improved survival. Our report suggests that even large randomized clinical trials may have a minimal impact on practice if their results run counter to belief in the value of the treatment.

Nonritual alcohol drinking practices among high school students from the Kibbutz movement in Israel: implications for prevention.

This article describes the Kibbutzim part of a survey conducted in the north of Israel during spring 1990, in order to investigate alcohol drinking habits of Jewish students from Kibbutzim and urban areas, as well as those of Moslem and Druze students, and to draw conclusions for designing alcohol abuse prevention activities. Of the general sample of 2763 students, 572 subjects were drawn from eleven schools which belong to sixty-two Kibbutzim. Exactly 435 students were Kibbutzim-born and 137 were outsiders living and being educated in the Kibbutzim. Kibbutzim-born youth showed the highest rate of involvement with alcohol in Israel, and a striking difference concerning the rates of alcohol consumption was revealed between the above mentioned two groups. This article explains this gap, as well as the high prevalence of alcohol use among Kibbutzim-born youth, and discusses implications for prevention.

Alcohol drinking habits of Israeli Jewish, Moslem and Druze adolescents in the north of Israel in 1990.

The article describes research conducted in the north of Israel on the drinking and smoking habits of 2,763 Moslem, Druze, Kibbutz and urban Jewish adolescents from a big city and a development town. It compares alcohol drinking frequencies (alcohol drunk on a single occasion) and amounts of these four youth populations, as well as cigarette smoking, and hashish use. Also students were asked about the drinking patterns of parents and best friends.
