Use of intravenous alfentanil-midazolam anesthesia for sedation during brief endourologic procedures.

Traditionally, general or regional anesthesia has been employed during endourologic procedures. The success of sedative-analgesic sedation during SWL prompted an investigation into its use in minor endourologic procedures. We compared intravenous alfentanil-midazolam anesthesia (n = 30) with spinal anesthesia (n = 35) during procedures such as ureteroscopy and stent placement using physiologic measures and patient and anesthetist ratings. The former series was prospective; the latter was retrospective. Physiologic measures remained stable and oxygen saturation was above 90% in all patients in both groups during the procedures. The average anesthesia and recovery room times were significantly shorter for patients given alfentanilmidazolam: 23.3 v 36.1 minutes and 85.5 v 179.6 minutes, respectively (P < 0.001; t-test), and this difference reduced the anesthesia cost an average of 46%. The anesthetists rated the intravenous regimen satisfactory in 92% of the patients, and 94% of the patients rated the procedure as comfortable. All 18 of the patients who had previously had spinal anesthesia considered alfentanil-midazolam superior. Intravenous alfentanil-midazolam sedation anesthesia can provide adequate analgesia for many minor endourologic procedures while shortening the anesthesia recovery time.

[Predictors of sexual behavior in a group of heterosexual university students at risk for AIDS in Montreal].

In order to evaluate the predictors of risky sexual behavior and AIDS, 573 male and female college students enrolled in French speaking universities in Montreal answered a questionnaire dealing with their sexual behaviors, from which an index of risks was computed (CASH). The analyses show that the best predictors of the CASH for men are associated to their sexual partner taking the pill, peer attitudes toward sexuality and individual sensation-seeking index. For women the best predictors of risky sexual behaviors are the perception of chances to catch AIDS, use of drugs or alcohol during coital behavior, peer group attitudes, personal sexual attitudes and using the pill as a contraceptive. These results suggest that risky sexual behaviors depend on complex processes associated to lifestyle and personality structures.

[Sexual attitudes and scenarios among students in France, Quebec, and Spain].

Sexual behaviors and attitudes were surveyed among 787, 17-21 years-old students in Lyon (France), Montreal (Quebec) and Salamanque and Madrid (Spain). Near 55% have had intercourse and oral sex in France, while this was the case of almost 80% in Quebec and only about 30% in Spain. Students from France and Quebec were younger at first intercourse, have had more sexual partners, and higher frequencies of intercourse and oral sex than those from Spain. Girls from Quebec have shown higher sexual permissiveness than other girls. Spanish students, particularly girls, consider their parents' sexual attitudes as far less permissive. Religiosity and church attendance seem to still put a strong damper, in Spain, on young people's sexual behaviors.

[Risky sex and contraception in students in France, Quebec and Spain].

In the context of a transational study, 404 sexual active 17-21 years-old students living in Lyon (France), Montreal (Quebec) and Salamanque and Madrid (Spain) have answered a questionnaire dealing with their contraceptive patterns, their perceptions of AIDS and their risky sexual behaviors. Results show that each group uses a different contraceptive strategy. In France and in Quebec those who had their first intercourse before 17 years of age used oral contraceptive rather than the condom. As for AIDS girls from Quebec had a higher index of risky sexual behaviors (CASH) than French, but the opposite was true among boys, while both girls and boys from Spain adopted safer sexual behaviors. Multiple regression analysis shows that the CASH rests on different predictors according to each national context.

Homophobia and attitudes about AIDS.

A random sample of 407 French Canadian adults responded to a questionnaire about perception of AIDS. Negative attitudes about AIDS are better predicted by homophobia than other measures as are attitudes about extramarital relations and attitudes abut adolescent heterosexuality.

[Not Available].

The results of a poll on the attitudes towards death of a representative sample of the Quebec population are presented. The Templer Scale on death anxiety was employed. These results indicate that death is not a preoccupation which triggers a high degree of tension in Quebec society. However, education level, salary, religions belief, age and sex influence the distribution of responses. Moreover, this anxiety is tied to the non-permissiveness in relation to sexuality as well as to sexism.
