Comparison of three antipsychotics in the emergency psychiatric setting.

In the present naturalistic study, the effectiveness and safety of quetiapine, risperidone and olanzapine were compared in the treatment of non selected acutely psychotic patients. It was observed that the rate of antipsychotic switch because of a lack of efficacy or side effects was higher in the quetiapine treated cases in comparison with the risperidone or olanzapine treated cases. The proportion of cases concomitantly treated with typical neuroleptics was significantly higher in the quetiapine group compared with the other two groups. In the outcome of non crossover cases, there were more improvements in the risperidone and olanzapine groups than in the quetiapine group. The results of this study suggest that quetiapine is not as efficacious as risperidone or olanzapine in the emergency psychiatric setting. Due to the methodological limitations of the study, these results must be considered preliminary and need confirmation.

Sexual behavior and sexual problems among patients with severe chronic psychoses.

The aim of the present study was to investigate sexual behavior in population of psychiatric patients affected by schizophrenia, schizoaffective disorder or bipolar disorder by means of an ad hoc questionnaire designed to explore the three phases of the sexual response: desire (or interest), arousal, and performance. The study assessed patients' attitude toward sexuality, several aspects of their sexual behavior, including patients' awareness of the risk of sexually transmitted diseases (STD), contraceptive strategy preferred by patients, and sexual effects of psychotropic medication. Patients reported a high frequency of sexual dysfunction, in particular, hyposexuality. Schizophrenia diagnosis and female gender were associated with lower levels of sexual performance. The impact of psychotropic drugs on patients' sexuality was significant, with both positive and negative effects. Although 65.8% of patients reported to be concerned about the risk of contracting infections during sexual intercourse, most of them engaged in sexual behavior at high risk for acquisition and transmission of STD. Patients' compliance with contraceptive measures was poor.

Diabetes is not a risk factor for tardive dyskinesia: a retrospective observational study.

The aim of this observational study was to compare the prevalence of tardive dyskinesia (TD) in diabetic and non diabetic patients. We compared 34 diabetic patients with 34 non diabetic controls, matched by sex, age and time of admission, who had received a complete neuropsychiatric evaluation and who had been exposed to antidopaminergic treatment for at least 3 months. Among them, 8 of 24 diabetic (33.3%) and 6 of 15 (40.0%) non diabetic patients presented TD. The prevalence of TD in the diabetic group is numerically lower than in the controls but the difference is not statistically significant (chi(2) = 0.006; fd = 1; p = 0.937). These results suggest that diabetes is unlikely to play a major role in the pathogenesis of TD.

Three cases of improvement of tardive dyskinesia following olanzapine treatment.

To date, clozapine is the only antipsychotic agent that has established itself as having minimal, if any, risk of tardive dyskinesia (TDk). In patients with TDk, clozapine permits the dyskinesia to disappear in approx. 50% of cases, particularly those with dystonic features, i.e. tardive dystonia (TDt) (Gardos, 1999). Unfortunately, clozapine is not always efficacious. Furthermore, some patients cannot be treated with clozapine because of its side-effects. Olanzapine is a serotonin-dopamine-receptor antagonist, which has an affinity for neuroreceptors similar to that of clozapine. Pooled tolerability data from controlled trials show that the overall incidence of TDk in patients treated with olanzapine is significantly lower than in patients treated with haloperidol (Tollefson et al., 1997). Here, we report three cases of patients affected by tardive disorders who dramatically improved after olanzapine treatment.
