Psychiatry is now subject to two apparently contradictory movements. On the one hand, the need to respect the autonomy and rights of patients is reinforced and coercive measures are strictly defined and limited. On the other hand, security concerns in our society leads to prosecution of psychiatric disorders, especially when accompanied by behavioral problems or criminal acts. In these situations of compulsory treatment or care provided in prisons, a number of dilemmas emerge. The place of the healthcare professional in treatments ordered by the Justice and problems related to administrative detention are discussed in more detail.

Mood disorders represent the most prevalent psychiatric condition in patients infected by HIV virus. Screening and treatment of depression as well as the evaluation of the risk suicide is of the utmost importance. When psychopharmacological treatment is required, interaction with antiretroviral treatment must be carefully considered. More generally a close collaboration between the physician and the psychiatrist is recommended.

Current explanatory models for binge eating in binge eating disorder (BED) mostly rely onmodels for bulimianervosa (BN), although research indicates different antecedents for binge eating in BED. This studyinvestigates antecedents and maintaining factors in terms of positive mood, negative mood and tension in asample of 22 women with BED using ecological momentary assessment over a 1-week. Values for negativemood were higher and those for positive mood lower during binge days compared with non-binge days.During binge days, negative mood and tension both strongly and significantly increased and positive moodstrongly and significantly decreased at the first binge episode, followed by a slight though significant, andlonger lasting decrease (negative mood, tension) or increase (positive mood) during a 4-h observation periodfollowing binge eating. Binge eating in BED seems to be triggered by an immediate breakdown of emotionregulation. There are no indications of an accumulation of negative mood triggering binge eating followed byimmediate reinforcing mechanisms in terms of substantial and stable improvement of mood as observed inBN. These differences implicate a further specification of etiological models and could serve as a basis fordeveloping new treatment approaches for BED.

BACKGROUND: The feasibility of clinical trials depends, among other factors, on the number of eligible patients, the recruitment process, and the readiness of patients to participate in research. Seeking patients' views about their experience in research projects may allow investigators to develop more effective recruitment and retention strategies. METHODS: A total of 100 patients consecutively admitted to a psychiatric university hospital were interviewed with respect to their willingness to participate in a study. For a different study scenario, patients were asked whether they would be ready to participate if such a study were organized in the service and to indicate their reasons for refusing or for participating. RESULTS: The general readiness to participate in a study ranged between 70% and 96%. The prospect of remuneration did not notably augment the potential consent rate. The most common and spontaneous motivation for agreeing to take part in a study was to help science progress and to allow future patients to benefit from improved diagnosis and treatment (87%). The presence or lack of a financial incentive was rarely chosen as an argument to agree (23%) or to refuse (7%) to participate. Patients relied mainly on their treating physicians when contemplating possible participation in a study (family physician [65%] and hospital physician [54%]). CONCLUSIONS: Clinicians and, in particular, treating doctors can play an important role in facilitating the recruitment process.

Anatomical structures and mechanisms linking genes to neuropsychiatric disorders are not deciphered. Reciprocal copy number variants at the 16p11.2 BP4-BP5 locus offer a unique opportunity to study the intermediate phenotypes in carriers at high risk for autism spectrum disorder (ASD) or schizophrenia (SZ). We investigated the variation in brain anatomy in 16p11.2 deletion and duplication carriers. Beyond gene dosage effects on global brain metrics, we show that the number of genomic copies negatively correlated to the gray matter volume and white matter tissue properties in cortico-subcortical regions implicated in reward, language and social cognition. Despite the near absence of ASD or SZ diagnoses in our 16p11.2 cohort, the pattern of brain anatomy changes in carriers spatially overlaps with the well-established structural abnormalities in ASD and SZ. Using measures of peripheral mRNA levels, we confirm our genomic copy number findings. This combined molecular, neuroimaging and clinical approach, applied to larger datasets, will help interpret the relative contributions of genes to neuropsychiatric conditions by measuring their effect on local brain anatomy.Molecular Psychiatry advance online publication, 25 November 2014; doi:10.1038/mp.2014.145.

OBJECTIVE: To examine the relation between depression and substance use in adolescents and the concomitant courses of both disorders. METHODS: Four individual interviews were administered to 85 adolescent substance users aged 14-19 years (mean 17.1 years, SD 1.4) over a 3.5 year period using the Adolescent Drug Abuse Interview (ADAD) and the Beck Depression Inventory (BDI-13). RESULTS: No predictive effect was observed on one dimension over the other, but each dimension was predictive of its own course. A decrease in substance-use severity paralleled a decrease in depressive state. Similarly, stable substance-use rates, either at a low or a high level, tended to be associated with low or high levels of depression, respectively. However, an increase in substance use was not accompanied by an increase in depressive states. Moreover, depression varied greatly between adolescents, and according to gender and age. CONCLUSIONS: Depressive states and substance use in adolescents can vary considerably overtime, and are closely but rather synchronically related. Since most of the adolescents do not seek help for substance-related problems, substance use should be systematically assessed in adolescents presenting with a depressive state.

Elevated schizotypy relates to similar cognitive attenuations as seen in psychosis and cannabis/polydrug use. Also, in schizotypal populations cannabis and polydrug (including licit drug) use are enhanced.These cognitive attenuations may therefore either be a behavioral marker of psychotic (-like) symptoms or the consequence of enhanced drug use in schizotypal populations.To elucidate this, we investigated the link between cognitive attenuation and cannabis use in largely pure cannabis users (35) and non-using controls (48), accounting for the potential additional influence of both schizotypy and licit drug use (alcohol, nicotine). Cognitive attenuations commonly seen in psychosis were associated with cannabis and alcohol use, but not schizotypy. Future studies should therefore consider (i) non-excessive licit substance use (e.g., alcohol) in studies investigating the effect of cannabis use on cognition and (ii) both enhanced illicit and licit substance use in studies investigating cognition in schizotypal populations.

In this retrospective pragmatic study, we define the necessary conditions that allow outpatient low dose intravenous neuroleptization, when hospitalization should otherwise be required. Intravenous neuroleptization is infrequently used in the outpatient treatment of acute psychotic decompensation. Rapid tranquilization with high dosage neuroleptics is controversial, and has a high risk of side effects. The indications for and potential advantages of this method in the perspective of a long-term ambulatory treatment are discussed by comparing a group of outpatients treated with infusions to a group of hospitalized patients. The method offers a satisfactory alternative to hospitalization for subjects who are not in imminent danger (current GAF rating between 20 and 40) and whose normal functioning is good (past year GAF rating = 70). Previous repeated hospitalizations favor the choice of hospitalization over infusion. Its potential advantages are the rapid evolution of the condition, with controlled regression but without psychosocial withdrawal, and an improvement in the patient's attitude towards treatment.

BACKGROUND AND PURPOSE: Surgical clipping of unruptured intracranial aneurysms (UIAs) has recently been challenged by the emergence of endovascular treatment. We performed an updated systematic review and meta-analysis on the surgical treatment of UIAs, in an attempt to determine the aneurysm occlusion rates and safety of surgery in the modern era. METHODS: A detailed protocol was developed prior to conducting the review according to the Cochrane Collaboration guidelines. Electronic databases spanning January 1990-April 2011 were searched, complemented by hand searching. Heterogeneity was assessed using I(2), and publication bias with funnel plots. Surgical mortality and morbidity were analysed with weighted random effect models. RESULTS: 60 studies with 9845 patients harbouring 10 845 aneurysms were included. Mortality occurred in 157 patients (1.7%; 99% CI 0.9% to 3.0%; I(2)=82%). Unfavourable outcomes, including death, occurred in 692 patients (6.7%; 99% CI 4.9% to 9.0%; I(2)=85%). Morbidity rates were significantly greater in higher quality studies, and with large or posterior circulation aneurysms. Reported morbidity rates decreased over time. Studies were generally of poor quality; funnel plots showed heterogeneous results and publication bias, and data on aneurysm occlusion rates were scant. CONCLUSIONS: In studies published between 1990 and 2011, clipping of UIAs was associated with 1.7% mortality and 6.7% overall morbidity. The reputed durability of clipping has not been rigorously documented. Due to the quality of the included studies, the available literature cannot properly guide clinical decisions.

Q-sort is a research method which allows defining profiles of attitudes toward a set of statements, ordered in relation to each other. Pertaining to the Q Methodology, the qualitative analysis of the Q-sorts is based on quantitative techniques. This method is of particular interest for research in health professions, a field in which attitudes of patients and professionals are very important. The method is presented in this article, along with an example of application in nursing in old age psychiatry.

Aim: There is a scarce literature describing psychological interventions for a young, first-episode cohort who have experienced psychotic mania. This study aimed to assess whether a manualized psychological intervention could be effective in reducing symptomatology and relapse, and improve functional outcome in this population. Methods: The study was an open-label design, drawn from a larger pharmacotherapy trial. All participants in the pharmacotherapy trial were offered a manualized psychological intervention in addition to case management. Inclusion in the psychotherapy group was based on participant's choice, and on completion of four or more of the eight modules offered. All clinical files were audited to ensure accuracy of group allocation. Forty young people aged 15 to 25 years old who had experienced a manic episode with psychotic features were recruited into the study, with 20 people in the combined treatment as usual plus psychotherapy group (P+TAU), and an equal number of matched control participants who received treatment as usual (TAU) within the same service. All participants were prescribed antipsychotic and mood-stabilizing medication. Symptomatic, functional and relapse measures were taken both at baseline and at 18-month follow-up. Results: Manic symptoms improved significantly for both groups, with no differences between groups. Depression scores and overall symptom severity were significantly lower in the P + TAU group. No differences were evident between groups with regard to numbers or type of relapse. The P + TAU group had significantly better social and occupational functioning after 18 months. Conclusion: This study suggests that a manualized psychological intervention targeted to a first-episode population can be effective in reducing depression and overall symptom severity, and can improve functional outcome following a first episode of psychotic mania.
