Comparative Study
[Validation of the QFS measuring the frequency and satisfaction in social behaviours in psychiatric adult population].
Although everyone working in routine mental health services recognizes the scientific and ethical importance to ensure that treatments being provided are of highest quality, there is a clear lack of consensus regarding what outcome domains to include, what measure of assessment to use and, moreover, who to question when assessing. ⋯ The QFS presented here is a brief, simple and easy to administer self-rating scale that displays satisfactory psychometric properties. It seems to be a valuable instrument for the monitoring of social functioning in psychiatric patients which, from a therapeutic point of view, may have a clear impact as it sets up expectation of change and allows both to reality test patients and therapists beliefs about the presence of progress or not and to identify if therapy is working on this specific outcome domain. Though, to date, the administration of the QFS to other populations and treatment modalities requires further investigation.

Case Reports
[Atypical antipsychotics and sexual dysfunction: five case-reports associated with risperidone].
Sexual and reproductive function side effects of atypical antipsychotics are frequent, often underestimated and badly tolerated. They contribute to the 50% rate of non-compliance reported for treated patients. Prevalence of sexual dysfunction associated with atypical antipsychotic treatment is high, varying from 18 to 96%. Atypical antipsychotics aren't, as a group, much better than typical antipsychotics, and among them, risperidone seems to induce more and quetiapine less sexual dysfunction. Most atypicals are non-selective, and have actions on multiple central and peripheral receptors. Among these, dopaminergic blockade could have a direct - altering motivation (desire) and reward (orgasm) - and an indirect negative influence on sexuality. Actually, the secondary hyperprolactinemia induced by some antipsychotics (typical antipsychotics, risperidone and amisulpiride), is dose-dependent, more pronounced for female patients, and may have a detrimental effect on sexual function. It also may result in hypogonadism, particularly for female patients. The long-term consequences of this secondary hypogonadism are subject to debate but potentially severe. Furthermore, the blocking and/or modulating actions of atypical antipsychotics on adrenaline, serotonine, histamine or acetyl-choline receptors all have the potential to contribute to secondary sexual problems. The pharmacological profile of risperidone, characterized by a strong affinity for D2 and alpha1 receptors, correlates with his tendency to significantly elevate prolactin levels and to produce ejaculatory disturbances. FIVE CASE-REPORTS: We describe five case-reports of sexual or hormonal disturbances associated with risperidone treatment: two cases of ejaculatory disturbance, one case of galactorrhea and two cases of amenorrhea. Alberto and David are two young male schizophrenic patients, treated with risperidone, and complaining of a total absence of ejaculation despite a preserved orgasm. Many recent case-reports describe the occurrence of retrograde ejaculation associated with risperidone but the exact prevalence is unknown. Retrograde ejaculation is thought to be related to the strong adrenolytic activity of risperidone. Alberto refused his medication because the ejaculatory dysfunction was unbearable for him. A switch to haloperidol depot was eventually well tolerated, without any sexual complaints. His case emphasizes the importance of sexual function for self-esteem and how this may amplify the intolerance to side-effects. David is on depot-risperidone in a setting of a legally forced treatment. Though he - reluctantly - accepts his medication, this side effect exacerbates his pre-existing delusions, strongly focused on sexual themes. His case illustrates how intolerance to sexual side-effects may be amplified by nature of delusions. Mireille is a 58 year old psychotic female patient, whose 2 mg risperidone treatment produced a unilateral galactorrhea. This sign became problematic because potentially visible at a time when Mireille started an activity in a sheltered occupation in town. Lowering dosage of antipsychotic allowed disappearance of the problem. Subjective responses to galactorrhea have been reported to be highly individual. Apart being a potentially visible side-effect, it may be misinterpreted as evidence of pregnancy or of a tumoral process. The cases of Ermina and Denise illustrate two contrasted situations in terms of subjective tolerability of reproductive function side-effects. Both were pre-menopausal patients with hyperprolactinemia secondary to risperidone treatment, resulting in amenorrhea. This was unbearable for Ermina. A switch to olanzapine allowed, one month later, the menses to resume. For Denise, on the other hand, the amenorrhea was a positive event, freeing her of unpleasant menses. ⋯ The described cases indicate that solving the problem is often possible, provided that individual preferences and subjective impact are taken in account. Antipsychotic treatment is often prescribed for very long periods. A better knowledge of - and attention to - the associated side effects, particularly on the sexual and reproductive functions, is necessary in order to reduce some potentially negative long-term effects and to improve the adherence to treatment of our patients.

Despite immense importance of auditory verbal hallucinations (AVHs) in the phenomenology of schizophrenia, the neurocognitive and neurophysiological bases of AVHs remain obscure. On the neurocognitive level, it has been proposed that AVHs arise from the disordered monitoring manifested by patients' inability to recognize their inner speech as being their own. On the neurophysiological level, the AVHs have been attributed to the aberrant activity in the primary auditory cortex (Heschl's gyrus). Although interesting, these models cannot account for the very specific and restricted content of AVHs in individual patients. The specific content of AVHs persists across different psychotic episodes even after extended periods of remission. Furthermore, the AVHs are usually triggered by emotionally charged and stressful situations. ⋯ Finally, in contrast to our initial hypothesis we did not observe any significant differences between processing of the hallucinated versus non-hallucinated words in the primary auditory cortex. In retrospect, this result is not surprising because patients did not experience internally generated AVHs while in the scanner, but instead were exposed exclusively to externally generated stimuli.

We report the case of a young woman who deve-loped catatonic syndrome a few days after neuroleptic mali-gnant syndrome (NMS), arising the problem of the chronology of both affections. A 20-year old woman with an history of bipolar disorder, experienced an acute manic syndrome that made hospitalization necessary. Fourteen days after loxa-pine prescription, the patient developed a NMS (DSM IV criteria) dyskinesia, dysphagia, fever and alteration of cons-ciousness. ⋯ A catatonic syndrome is regard as an acute form of malignant syndrome. In the other way, a severity scores of malignant syndrome are correlated among catatonic signs. In this case report, we suggest that the neuroleptic malignant syndrome accelerate the evolution to catatonic syndrome.
