The sixth report of the National Confidential Survey on Maternal Deaths provides insights into the frequency, risk factors, causes, adequacy of care, and preventability of maternal deaths occurring in 2013-2015 in France. The method developed ensures an exhaustive identification and a confidential analysis of maternal deaths. It was organized in three steps. 1) All deaths occurring during pregnancy or up to 1 year after its end, whatever the cause or mode of termination, being considered 2) A pair of volunteer assessors (midwives, gyneco-obstetricians, anesthesiologists, psychiatrists) was in charge of collecting the information (history of the woman, course of her pregnancy, circumstances of the event that led to the death and management); 3) Review and classification of deaths by the National Committee of Experts on Maternal Mortality which made a collective judgment on the cause of death, on the adequacy of the care provided, and on what could been done to avoid the death depending on the existence of circumstances that could have prevented the fatal outcome. The operation of the committee has been enriched by new resources to further explore these cases. Specifically, a module of the survey questionnaire, the recruitment of psychiatrists whose contribution allows relevant documentation of the suicides, and the participation of a psychiatrist as an associate expert for the analysis of the appropriateness of the management and the variable determining factors of these cases. Suicide becomes one of the two main causes of maternal mortality, (the other cause being cardiovascular pathologies), with 35 suicides on the triennium among the 262 maternal deaths, that is to say 13.4 % of maternal deaths, about 1 per month. In this population, the average age of women who died by suicide was 31.4years. The majority of the women were born in France, 68 % were prima parous, and in 9 % of cases suicide followed a twin pregnancy. Psychiatric history was known in 33.3 % of the suicidal mothers, and 30.3 % had a history of psychiatric care that was unknown to the maternity team.43 % of the women had psychosocial vulnerability factors, a history of violence, and eviction from the home and/or financial difficulties. In 23 % of the cases, the time of occurrence of these suicides was within the first 42days postpartum, and in 77 % between 43 days and one year after birth with a median delay of 126days. Only one suicide occurred during pregnancy. Maternal suicides were mostly violent deaths. Suboptimal care was present in 72 % of cases, where 91 % of potentially preventable deaths related to a lack of multidisciplinary management and/or inadequate interaction between the patient and the health care system. Among these potentially avoidable deaths, we were able to distinguish: women whose psychiatric pathology was known and for whom multidisciplinary management was not optimal, and women whose psychiatric pathology was not known or was not present - for whom it was rather a matter of a failure to detect and identify the signs, particularly by obstetric care providers or general emergency services. Based on the analysis of the cases, strong messages were identified, with the aim of optimizing management: - The screening by structured questioning of psychiatric history from the moment of registration in the maternity ward, repeated at each consultation throughout the pregnancy. - The reassessment of the psychological and somatic state through an early postnatal interview at one month; - The identification of warning symptoms, with screening tools for depression. If necessary, a further recourse to the psychologist and/or psychiatrist of the maternity hospital, organisation of a home hospitalization, and a private midwife to provide a link in the pre- and postpartum period. This, in addition to the earliest possible care in the PMI (Maternal and Infantile Protection, of the French social care system), appointments with mental health professionals,and the link with the attending physician; - The implementation of a coordinated care pathway in case of a known psychiatric pathology with pre conception counselling. This includes a multidisciplinary collaboration, an adaptation of psychotropic treatment, management of comorbidities referral to specialized perinatal psychopathology teams, prenatal meeting with the pediatrician of the maternity hospital, anticipation of the birth, postpartum and discharge options, liaison sheet established for the organization of the delivery and postpartum, and a regular written transmissions between the intervening parties throughout the care; - The generalization of medico-psycho-social staffs, in maternity wards, for all situations identified as at risk. In addition to the need for training and increased awareness on psychological issues during the perinatal period and on the different pathologies encountered by adult mental health professionals and front-line workers, it is necessary to encourage the development of resources in the country. Particularly, joint child psychiatrist-adult psychiatrist consultations at the territorial level, responsible for being resource contacts for maternity wards and local care professionals, as well as the promotion of case pathway referrals.

Psychiatric disorders (more specifically mood disorders and psychosis) represent the 1st cause of disability among young people. Unemployment rate between 75 to 95% for the person with schizophrenia. It is correlated to poor social integration and bad economic status, worse symptomatology loss of autonomy as well as global bad functioning. It is responsible of more than half of the overall cost of psychosis. The onset of most of psychiatric disorders occur between the age of 25 and 35 years old, a critical time in young adult life when they should build their professional as well as social future. Without appropriate care, young adult are unable to build satisfactory emotional relationships, continue their studies, live independently or fit into life. They are frequently dependent on their environment. They also have an increased suicide rate and frequent comorbid substance abuse. Despite this context, their care pathway is often marked by a delay or premature stop of care, drug treatments not always suitable and a lack of specific relay post-hospitalization regarding continuity of professional training or studies. All factors impacting future employability of adolescents. Furthermore they spend most of their time in school and school plays a key part in an individual's development including peer relationships, social interactions, academic attainment, cognitive progress, emotional control, behavioral expectations and physical and moral development. These areas are also reciprocally affected by mental illness. The initial phases of FEP are characterized by impaired academic performance, change in social behaviors and increasing absences from school, reflecting the prodrome of the illness that leads to disengagement from education. Functional decline often precedes onset of clinical symptoms and many adolescents and young adults are therefore isolated from school before their illness is recognized. School support staff may fail to recognize those who are functionally impaired because of evolving FEP although school is a key setting for promoting positive mental health, fostering resilience, detecting and responding to emerging mental ill health. So, people with psychotic illness have low levels of secondary school completion. School dropout has been defined as leaving education without obtaining a minimal credential, most often a higher secondary education diploma. In France, the school is compulsory up to the age of 16. Consequences are significant: among young people without a degree out of initial training for one to four years and present on the labour market, 47% are unemployed. School dropout depends on a number of factors, including grades, family and social environment and the relationship with the school, but also the emergence of psychiatric disorders. For first episode psychotic patients, age of onset, lack of family support, longer duration of psychosis, levels of premorbid global functioning and education, negative and cognitive symptoms, addictions, depressive comorbidities and stigma plays an important role in school dropout. However, young adults have historically received less treatment than expected considering prevalence of mental illness at that age. In the last few decades, early intervention programs for psychosis have been developed all around the world in order to promote rehabilitation and prevent long-term disabilities. Early intervention programs focus on the special needs of young people and their families and engage in some form of assertive community treatment, which attempts to treat patients in the community rather than using inpatient services. For early intervention in psychosis programs, the goal is to keep patients engaged with treatment, prevent them from further psychotic episodes and hospitalizations and promote rehabilitation. The additional services of an early intervention program include staff specialized in psychosis treatment, family/group/individual counseling sessions, assertive case management, and low-dose second generation anti-psychotics. In these programs, psychiatric rehabilitation practitioners already use individual counseling and supported education programs (SEd) to improve postsecondary educational outcomes. The goals of SEd are for individuals with serious mental illness to successfully be able to set and achieve an educational goal (e.g., training certificate or degree), to improve educational competencies (literacy, study skills, time management), to navigate the educational environment (e.g., applications, financial assistance), and to improve motivation toward completing educational goals. These approaches are often combined with efforts to support transitions to sustainable employment. Current evidence of these interventions are weak with limited information on specific difficulties experienced by young adults with FEP in educational tasks. Adaptive strategies are needed by young adults with FEP to succeed in educational settings but most studies do not explore it with rigorous methodology. However, common SEd components emerge: specialized and dedicated staffing, one-on-one and group skill-building activities, assistance with navigating the academic setting and coordinating different services, and linkages with mental health counseling. Continued specification, and testing of SEd core components are still needed. It is important that occupational therapy researchers and practitioners develop, and evaluate effective interventions to improve education outcomes for young adults with FEP. The objective of this work is to define school dropout, assess causes and consequences of FEP. How to help young people to maintain education? We will detail measures to support the academic re-insertion in France.

Resume La loi du 5 juillet 2011 sur les soins psychiatriques sans consentement repond a la necessite d’une harmonisation europeenne et a l’urgence imposee par le Conseil Constitutionnel qui declarait la loi du 27 juin 1990 inconstitutionnelle en aout 2011. Elle s’inscrit dans un climat securitaire mais tente de trouver un equilibre entre les droits et la liberte des patients d’une part et la contrainte au soin d’autre part. Cette loi introduit de nouveaux acteurs dans les soins sous contrainte en donnant une place importante au juridique, elle permet de nouvelles pratiques avec les soins ambulatoires sans consentement et la possibilite d’hospitaliser sous contrainte sans tiers avec le peril imminent. Comment ce dispositif particulier qu’est le peril imminent s’est-il inscrit dans nos pratiques ? Quel peut etre son impact sur les patients et leurs proches, ainsi que sur les rapports medecin-patient ? Nous tenterons d’extraire des elements de reponses a partir de l’experience du centre hospitalier Sainte-Anne en s’appuyant sur les hospitalisations sous contrainte de 2010 a 2012.

Schizophrenia is a debilitating disease that usually begins in young adulthood, at a time when a person would usually make the transition to independent living, but it can occur at any age. The symptoms and behaviour associated with psychosis and schizophrenia have a distressing impact on the individual, and the family. The course of schizophrenia varies considerably. Although most patients will recover, some will have persisting difficulties or remain vulnerable to future episodes. Therefore, stabilisation of patients in acute phases and avoidance of relapse are major objectives of management throughout the course of this disease. The purpose of this article is to clarify the stabilisation, to study the contributing factors and strategies to implement to achieve stability, through a literature review and key guidelines. Thus, the patient is stabilised when productive symptoms and behavioural problems have decreased. So, the stable phase represents a prolonged period of treatment and rehabilitation during which symptoms are under adequate control and the focus is on improving functioning and recovery. Important predictive criteria of stabilisation include: positive symptoms, the number of previous relapses, cooperation with the patient and family, good adherence to treatment and the use of long acting injectable second-generation antipsychotics. After an acute relapse, the careful organization of the discharge and the development of a proposed ambulatory care in tailored care structures will help consolidate stabilisation and obtain remission. Accepting the idea of continuing treatment is a complex decision in which the psychiatrist plays a central role beside patients and their families. The course of integrated actions on modifiable risk factors such as psychosocial support, addictive comorbidities, identification of prodromes, active information for the therapeutic education of patients and families and access to care will also be supported. This would improve the functional abilities of patients, their social adaptation and particularly their quality of life.

Resume Une etude pharmacoepidemiologique observationnelle, prospective, nationale, multicentrique : REALITE LT a permis d’analyser les donnees cliniques et les modalites d’utilisation de la loxapine chez une population de 645 patients souffrant de schizophrenie et traites par cet antipsychotique depuis au moins quatre mois. L’etude s’est deroulee sur un semestre avec recueil des caracteristiques sociodemographiques, cliniques (sous-types et formes evolutives de schizophrenie), therapeutiques, de tolerance et d’observance. Ces donnees ont ete comparees a une precedente etude REALITE et aux resultats d’autres etudes naturalistiques de patients schizophrenes traites. Les resultats confirmaient la validite de la population d’etude : anciennete de la psychose (50 % au-dessus de dix ans) et du traitement par loxapine (28 mois), formes paranoide et desorganisee predominantes (80 %), frequence des comorbidites addictives. Le respect des recommandations quant au bon usage de la loxapine : posologie entre 75 et 200 mg par jour majoritaire (moyenne : 168,4 mg), monotherapie antipsychotique (27 %) maintenue au long cours avec stabilite posologique (69 %), le bon profil de tolerance avec peu d’effets secondaires extrapyramidaux moins de 9 %, peu de troubles metaboliques ; ces effets secondaires etaient correles avec des coprescriptions de plusieurs antipsychotiques. Quant a l’observance, elle etait jugee bonne dans quatre cas sur cinq.

Resume Introduction Le syndrome de Usher est une maladie genetique comportant une double deficience sensorielle (auditive et visuelle) appelee surdicecite. Des troubles psychiatriques peuvent etre associes, compliquant le diagnostic mais aussi la prise en charge du fait de la reduction d’autonomie et des difficultes de communication. Cas clinique A l’occasion du suivi, dans son service de secteur psychiatrique, d’un patient actuellement âge de 57 ans, considere comme psychotique chronique severe, resistant, hospitalise a plusieurs reprises pour des etats aigus, avec deni des troubles et opposition aux soins, l’exploration d’une surdite ancienne appareillee, associee a une cecite qui a progresse entre 40 et 50 ans, a fait proceder a un bilan a visee diagnostique mais aussi pronostique et therapeutique : ORL, ophtalmologique et neuroradiologique qui a permis d’etablir le diagnostic de syndrome de Usher type 2. Alors qu’il s’etait toujours montre opposant aux soins psychiatriques, le patient a accepte le bilan et les consultations du medecin generaliste de l’hopital et des differents specialistes, et par le biais des soins somatiques, la necessite d’un suivi a intervalle regulier avec mise en place d’un traitement antipsychotique au long cours. Conclusion L’etablissement du diagnostic d’une maladie genetique rare a permis une meilleure prise en charge du patient du fait d’une meilleure adhesion du patient aux traitements antipsychotiques, d’une meilleure comprehension et acceptation des difficultes liees au polyhandicap par l’equipe soignante psychiatrique, et de l’ouverture a un reseau de soins specialises permettant la mise en place de moyens de reassurance et de communication.

Le psychiatre presente au patient sa maladie de facon simple et ce le plus tot possible [17], sans pour autant formuler un diagnostic precis, notamment au debut de la prise en charge. Avec l’accord du patient, il informe egalement l’entourage qui a ete souvent le premier a deceler les troubles, et a diriger le patient vers les soins. L’entourage, sollicite pour l’accompagnement au long cours du patient, est generalement tres curieux du diagnostic et du pronostic ; cependant il convient de temporiser, meme vis-a-vis des proches. Le psychiatre aide le patient a decrypter ses symptomes ; cela lui permet de justifi er l’instauration du traitement et de lui apprendre a reperer par la suite les signes d’une eventuelle rechute. Il informe sur la maladie, son histoire naturelle, son pronostic et l’ensemble des soins necessaires (traitements medicamenteux, strategies psychotherapeutiques et mesures psychosociales), en prenant en compte les principaux facteurs psychologiques, sociaux et educatifs de chaque patient. L’information porte donc sur l’ensemble des strategies ; l’abord medicamenteux Comment prescrire un APAP ?

Resume La prise de poids lors d’un traitement psychotrope chez les patients souffrant de troubles psychiatriques est connue depuis la decouverte des premiers psychotropes, mais elle semble s’intensifier depuis quelques annees. Elle est calculee a l’aide de l’indice de masse corporelle (IMC) et peut aller de la surcharge ponderale a l’obesite. C’est un facteur de risque important et elle expose a de nombreuses complications tant somatiques (hypertension arterielle, insuffisance coronarienne, accident vasculaire cerebral, intolerance au glucose, diabete non insulinodependant, dyslipidemie, troubles respiratoires, osteoarticulaires ou neoplasiques) que psychologiques et sociales (sentiment de demoralisation et de mise a l’ecart). Ces consequences parfois severes entrainent un risque d’interruption du traitement et de rechute de la pathologie traitee, et peuvent parfois engager le pronostic vital. L’article fait le point des etudes menees depuis quelques annees au point de vue de l’epidemiologie, mais aussi du mecanisme d’action et des possibilites de prise en charge des patients souffrant de prise de poids sous antidepresseurs, thymoregulateurs ou antipsychotiques. Des donnees generales, mais aussi specifiques a chacune des 3 classes medicamenteuses sont ici resumees et rapportees aux donnees de la litterature. Si les notions epidemiologiques sont mieux connues, les mecanismes etiologiques restent delicats a elucider (role du controle nerveux central, metabolisme du glucose, pharmacogenetique). Il faut souligner aussi leur association pour ces patients a la difficulte d’equilibrer leur alimentation, au manque d’exercice physique et aux associations medicamenteuses. La prise en charge comporte des mesures associant la surveillance reguliere et precoce du poids et de ses variations, un bilan biologique a intervalle regulier, des conseils hygieno dietetiques pouvant associer un regime prudent a une activite physique reguliere, mais aussi une prise en charge psychotherapeutique individuelle et dans le cadre de groupes de patients. L’instauration la plus precoce possible de ces mesures, associee a l’information donnee aux patients le plus tot possible par rapport a la prescription sont essentielles pour limiter cette prise de poids et les risques qu’elle genere, de mauvaise compliance ou d’interruption du traitement avec risque de rechute, voire d’accident majeur.

This article is a review of the various treatments that are currently available, in particular in France, for the treatment of bipolar disorders. This article specifically addresses the use of novel antipsychotic agents as alternative therapy to a lithium therapy and/or the use of conventional antipsychotics. The prevalence of bipolar disorder over a lifetime is around 1% of the general population. Bipolar disorder consists of alternating depressive and manic episodes. It mainly affects younger subjects, and is often associated with alcohol and drug addictions. There are two main subtypes of bipolar disorder. According to the DSM IV-R, type 1 of bipolar disorder is characterised when at least one manic episode (or a mixed episode) has been diagnosed. Type 2 of bipolar disorder is related to patients enduring recurrent depressive episodes but no manic episode. Type 2 affects women more frequently as opposed to type 1 affecting individuals of both sexes. Manic-depressive disorder (or cyclo-thymic disorder) appears in relation to patients who has never suffered manic episode, mixed episode or severe depressive episode but have undergone numerous periods with some symptoms of depression and hypomanic symptoms over a two-year period during which any asymptomatic periods last no longer than two months. The average age of the person going through a first episode (often a depressive one) is 20 years-old. Untreated bipolar patients may endure more than ten manic or depressive episodes. Finally, in relation to 10 to 20% of patients, the bipolar disorder will turn into a fast cycle form, either spontaneously or as a result of certain medical treatments. Psychiatrists are now able to initiate various treating strategies which are most likely to be effective as a result of the identification of clinical subtypes of the bipolar disorder. Lithium therapy has been effectively and acutely used for patients with pure or elated mania and its prophylaxis. However, lithium medication may worsen depressive symptoms when used for a long term maintenance therapy. Additionally, mixed mania, rapid cycling type patients and bipolar disorder associated with substance abuse do not respond well to lithium therapy. In addition to the lithium therapy or in place of a lithium therapy, one can report the frequent use of antipsychotic agents in respect of patients with bipolar disorder during both the acute and maintenance phases of treatment. Antipsychotic agents have been used for almost forty years and may be used in combination with a lithium therapy. Conventional antipsychotics are effective but they may induce late dyskinesia, weight gain, sedation, sexual dysfunction and depression. These adverse side effects often lead to non compliance in particular in circumstances where antipsychotic agents are combined with a lithium therapy. A number of alternative somatic treatment approaches have been reported for patients who do not respond well or who are intolerant to lithium therapy. As such, valproate has received regulatory approval for the acute treatment of mania and carbamazepine has been indicated for this condition in a number of countries. Divalproex (Depakote) has recently obtained the authorization to market in France and may be prescribed for manic states or hypomanic states that do not tolerate lithium therapy or for which lithium therapy is contraindicated. A number of other anticonvulsants (lamotrigine, gabapentin and topiramate) are currently being tested. Because of the side effects of the conventional antipsychotic agents, atypical antipsychotic agents are currently on trial and appear to be of interest in the treatment of bipolar disorders. Currently, a number of prospective studies are available with clozapine, risperidone and olanzapine in the treatment of bipolar disorder. Most are short-term studies. Recent randomised, double-blind, placebo-controlled studies have shown clozapine, risperidone and olanzapine to be effective with antimanic and antidepressive effects, both as monotherapy and as add-on maintenance therapy with lithium or valproate. They also have a favorable side effect profile and a positive effect on overall functioning. Similarly, valproate combined with antipsychotics provides greater improvement in mania than antipsychotic medication alone and results in lower dosage of the antipsychotic medication. There is currently no double-blind study regarding the use of clozapine for bipolar disorders. However, based on the results of a number of open-label studies, clozapine appears to be effective in relation to schizo-affective and bipolar patients including those with rapid cycling or those who respond inadequately to mood stabilizers, carbamazepine, valproate or conventional antipsychotics. Clozapine seems to be more appropriate for bipolar and schizo-affective patients than schizophrenics. In particular, studies show that patients with manic and mixed-psychotic state of illness are better responders than patients with major depressive syndromes. Four open studies suggest the efficacy of clozapine in the maintenance treatment of bipolar disorder and three prospective, open-label studies show the efficacy of clozapine in the manic state of the illness. However, the number of patients in the studies was not important and these studies are not controlled. Clozapine has also adverse side affects, one of which consisting of a major risk of agranulocytosis and, potentially, death. In addition, clozapine has been shown to produce significant weight gain and sialorrhea as well as significant anticholinergic effects. As a result, clozapine should not be prescribed in the first place. As opposed to clozapine, there are open-label reports and controlled studies in respect of risperidone and olanzapine. Two recent double-blind studies of acute mania found olanzapine to be more effective than placebo. Based on these two studies, olanzapine has recently been approved for the indication of mania. The effects of olanzapine and divalproex in the treatment of mania have also been compared in a large randomized clinical trial. The olanzapine treatment group had significantly greater mean improvement of mania ratings and a significantly greater proportion of patients achieving protocol-defined remission. Significantly more weight gain and cases of dry mouth, increased appetite and somnolence were reported with olanzapine while more cases of nausea were reported with divalproex. The comparison of olanzapine with lithium for the treatment of mania has also been the subject of a double-blind randomized controlled trial. That study shows no differences between the two drugs. While these studies support the idea that olanzapine has direct acute anti-manic effects, a number of authors are of the opinion that olanzapine may have specific prophylactic mood-stabilizing properties. Olanzapine would appear to be effective in the maintenance treatment, as it exhibited both antimanic and antidepressant effects. Systematic trials have shown that risperidone may be effective and safe in the treatment of acute mania, as an add-on therapy with lithium or valproate (open studies and two controlled double-blind studies) and as monotherapy (open studies). In an open, multi-center, 6-month study, risperidone seems to be effective and safe as long-term adjunctive therapy in treatment-resistant bipolar and schizo-affective disorders, with no exacerbation of manic symptoms. Risperidone had few adverse side effects (and where there were any, they were mostly mild), mostly consisting of APS and weight gain. A naturalistic comparison of clozapine, risperidone and olanzapine in the treatment of bipolar disorder suggests that the efficacy and tolerability of the three treatments are similar. One major differentiation factor of these drugs appears to be weight gain, particularly between olanzapine and risperidone. However, this may partially be caused by the use of mood-stabilizing agents. Bipolar and schizo-affective patients now require combination therapy approach because of the cyclic nature of these disorders. Many studies report the combination of mood-stabilizing agents with conventional antipsychotics and atypical antipsychotics. Combination therapies produce a number of adverse side effects. Atypical antipsychotics (other than clozapine) are now rated as first-line agents for adjunctive treatment of mania because they produce less adverse side effects. Atypical antipsychotics are also rated as first-line agents for combined treatment of psychotic depression and they are strongly preferred when an antipsychotic is required for long-term maintenance.

Schizophrenia is a debilitating disease that usually begins in young adulthood, at a time when a person would usually make the transition to independent living, but it can occur at any age. The symptoms and behaviour associated with psychosis and schizophrenia have a distressing impact on the individual, and the family. The course of schizophrenia varies considerably. Although most patients will recover, some will have persisting difficulties or remain vulnerable to future episodes. Therefore, stabilisation of patients in acute phases and avoidance of relapse are major objectives of management throughout the course of this disease. The purpose of this article is to clarify the stabilisation, to study the contributing factors and strategies to implement to achieve stability, through a literature review and key guidelines. Thus, the patient is stabilised when productive symptoms and behavioural problems have decreased. So, the stable phase represents a prolonged period of treatment and rehabilitation during which symptoms are under adequate control and the focus is on improving functioning and recovery. Important predictive criteria of stabilisation include: positive symptoms, the number of previous relapses, cooperation with the patient and family, good adherence to treatment and the use of long acting injectable second-generation antipsychotics. After an acute relapse, the careful organization of the discharge and the development of a proposed ambulatory care in tailored care structures will help consolidate stabilisation and obtain remission. Accepting the idea of continuing treatment is a complex decision in which the psychiatrist plays a central role beside patients and their families. The course of integrated actions on modifiable risk factors such as psychosocial support, addictive comorbidities, identification of prodromes, active information for the therapeutic education of patients and families and access to care will also be supported. This would improve the functional abilities of patients, their social adaptation and particularly their quality of life.

Data concerning the clinical and therapeutic characteristics of patients with schizophrenia treated by antipsychotic in naturalistic conditions are useful. Two national pharmacoepidemiological studies were conducted in France, a retrospective survey RÉALITÉ and a prospective study RÉALITÉ LT, to examine the use of loxapine, first in acute and chronic psychotic states and second in long-term treatment prescribed for patients with schizophrenia.The aim of RÉALITÉ LT is to specify the clinical characteristics of schizophrenic patients treated by loxapine for at least 4 months and the description of the methods of use of this antipsychotic medication during a 6-month follow-up in "real life" conditions.RÉALITÉ LT is an epidemiologic, observational, longitudinal, prospective (during a half-year period), multicenter and national study of the prescription of loxapine in routine clinical practice. For this study, 645 patients with schizophrenia treated by loxapine were recruited, assessed by PANSS, CGI, GAF, MeDra-SOC-PT for side effects and Girerd questionnaire for compliance; statistical analysis used SAS 9.2.Six hundred and forty-five adult patients were included and assessed at inclusion, month 3 and 6. These patients were mostly male (69%), with an average age of 41, inactive (68%), lonely with no child (79%), under psychiatric care for more than 5 years (81%), less than one third were inpatients. The subtypes of schizophrenia were paranoid (59%), disorganised (21%), undifferentiated or residual (10%), the outcome of psychotic illness was episodic (50%) or continuous (33%). The daily mean dosage of loxapine was 168,4 mg/d, in antipsychotic loxapine monotherapy (27%) or in combination with other antipsychotics (63%); it was often associated with psychotropic medications (anxiolytic [72%], antidepressant [21%], normothymic [19%]). The stability of the dosage of loxapine during the 6 months follow-up (60%) was associated with strict loxapine monotherapy or antipsychotic monotherapy (loxapine associated with other psychotropic medication). Safety, side effects and compliance were compared with previous studies.These results are discussed, comparing the two pharmacoepidemiological studies RÉALITÉ and RÉALITÉ LT, loxapine is used in compliance with the two indications (smpc) and French guidelines (HAS, Haute Autorité de santé).

Usher's syndrome is a heterogeneous autosomal recessive disorder characterised by dual sensory impairment: profound congenital hearing impairment and progressive visual loss due to retinitis pigmentosa, sometimes associated with vestibular dysfunction. Some patients develop a psychotic illness, the etiology of which is still debated. Diagnosis may be difficult, and there are only a few reports in the psychiatric literature.The present case reports a 57-year-old man, double diagnosed with sensory impairment and psychosis. The severity of his psychosis required several hospitalisations in a psychiatric in-unit, even under third party decision or compulsory hospitalisation, for acute states with disruptive behaviour, aggressiveness against his mother, persecutory delusion and auditory hallucinations, self-talking, major anxiety, and depressive affects, without dissociation. Deafness had been diagnosed when he was six years old; he was able to attend school and learn to read and speak, using hearing aids, and was able to hold a job for three months. Severe psychotic symptoms appeared when he was 18 years old and contributed in confirming the diagnosis. Progressive loss of vision until blindness began later, between the age of 40 to 50. No specific abnormal results were revealed during the neuroradiological check-up. Treatment consisted in antipsychotics, notably depot, first in a mental health care in-unit and subsequently in an out-patient unit: although he denied psychotic symptoms, he became compliant with medication and could go on with treatment, associated with multidisciplinary interventions at home, in order to improve his quality of life.Usher's syndrome is the most frequent cause of combined deafness and blindness in adults (three and five individuals per 100,000), but difficulties in communication need to increase clinical awareness of this disorder, especially for psychiatrists. Three subtypes are recognized by the International Usher Syndrome Consortium: Type 1 is characterised by profound congenital deafness, retinal degeneration beginning in childhood, and progressive vestibular dysfunction; Type 2 is characterised by moderate to severe hearing impairment, later onset of retinal degeneration, and normal vestibular function; Type 3 is characterised by progressive hearing loss and variable age of onset of retinal degeneration. Although nearly 23% may have psychotic symptoms, the aetiology remains unclear: sensory deprivation associated with environmental stress, organic changes such as cerebral abnormalities, genetic link (two genetic loci for both Usher's syndrome and psychotic illness are very close). Treatment of psychiatric symptoms is based on antipsychotics, well tolerated by the patients, who improve change of behaviour and communication abilities. Genetic counselling may be useful for parents.Access to mental health services is particularly difficult for deaf and deaf-blind people, and difficulties in communication are a challenge for patients and for caregivers too. Antipsychotic medications are helpful for associated psychotic symptoms. Potential link between Usher syndrome and psychosis is still unclear and needs further studies.

Weight gain is associated with the use of many psychotropic medications, including antidepressants, mood stabilizers, antipsychotic drugs, and may have serious long term consequences: it can increase health risks, specifically from overweight (BMI = 25-29.9 kg/m2) to obesity (BMIor =30 kg/m2), according to Body Mass Index (BMI), and the morbidity associated therewith in a substantial part of patients (hypertension, coronary heart desease, ischemic stroke, impaired glucose tolerance, diabetes mellitus, dyslipidemia, respiratory problems, osteoarthritis, cancer); according to patients, psychosocial consequences such as a sense of demoralization, physical discomfort and being the target of substantial social stigma are so intolerable that they may discontinue the treatment even if it is effective. The paper reviews actual epidemiological data concerning drug induced weight gain and associated health problems in psychiatric patients : there is a high risk of overweight, obesity, impaired glucose tolerance, diabetes mellitus, premature death, in patients with schizophrenia or bipolar disorder; and the effects of specific drugs on body weight: Tricyclic Antidepressants (TCA) induced weight gain correlated positively with dosage and duration of treatment, more pronounced with amitriptyline ; Selective Serotonin Reuptake Inhibitors (SSRI) decrease transiently bodyweight during the first few weeks of treatment and may then increase bodyweight; weight gain appears to be most prominent with some mood stabilizers (lithium, valproate); atypical antipsychotics tend to cause more weight gain than conventional ones and weight gain, diabetes, dyslipidemia, seem to be most severe with clozapine and olanzapine. Conceming the underlying mechanisms of drug induced weight gain, medications might interfere with central nervous functions regulating energy balance; patients report about: increase of appetite for sweet and fatty foods or "food craving" (antidepressants, mood stabilizers, antipsychotic drugs) and weight gain despite reduced appetite which can be explained by an altered resting metabolic rate (TCA, SSRI, Monoaminoxidase Inhibitors MAO I). According to current concepts, appetite and feeding are regulated by a complex of neurotransmitters, neuromodulators, cytokines and hormones interacting with the hypothalamus, including the leptin and the tumor necrosis factor system. The pharmacologic mechanisms underlying weight gain are presently poorly understood: maybe the different activities at some receptor systems may induce it, but also genetic predisposition. Understanding of the metabolic consequences of psychotropic drugs (weight gain, diabetes, dyslipidemia) is essential: the insulin-like effect of lithium is known; treatment with antipsychotic medications increases the risk of impaired glucose tolerance and diabetes mellitus. Several management options of weight gain are available from choosing or switching to another drug, dietary advices, increasing physical activities, behavioural treatment, but the best approach seems to attempt to prevent the weight gain : patients beginning maintenance therapy should be informed of that risk, and nutritional assessment and counselling should be a routine part of treatment management, associated with monitoring of weight, BMI, blood pressure, biological parameters (baseline and three months monitoring of fasting glucose level, fasting cholesterol and triglyceride levels, glycosylated haemoglobin). Psychiatrics must pay attention to concomitant medications and individual factors underlying overweight and obesity. Weight gain has been described since the discovery and the use of the firstpsychotropic drugs, but seems to intensify with especially some of the second generation antipsychotic medications ; understanding of the side effects of psychotropic drugs, including their metabolic consequences (weight gain, diabetes, dyslipidemia) is essential for the psychiatrics to avoid on the one hand a risk of lack of compliance, a discontinuation of the pharmacological medication and also a risk of relapse and rehospitalization, and on the other hand to avoid acute life threatening events (diabetic ketoacidocetosis and non ketotic hyperosmolar coma, long term risk complications of diabetes and overweight).

This article is a review of the various treatments that are currently available, in particular in France, for the treatment of bipolar disorders. This article specifically addresses the use of novel antipsychotic agents as alternative therapy to a lithium therapy and/or the use of conventional antipsychotics. The prevalence of bipolar disorder over a lifetime is around 1% of the general population. Bipolar disorder consists of alternating depressive and manic episodes. It mainly affects younger subjects, and is often associated with alcohol and drug addictions. There are two main subtypes of bipolar disorder. According to the DSM IV-R, type 1 of bipolar disorder is characterised when at least one manic episode (or a mixed episode) has been diagnosed. Type 2 of bipolar disorder is related to patients enduring recurrent depressive episodes but no manic episode. Type 2 affects women more frequently as opposed to type 1 affecting individuals of both sexes. Manic-depressive disorder (or cyclo-thymic disorder) appears in relation to patients who has never suffered manic episode, mixed episode or severe depressive episode but have undergone numerous periods with some symptoms of depression and hypomanic symptoms over a two-year period during which any asymptomatic periods last no longer than two months. The average age of the person going through a first episode (often a depressive one) is 20 years-old. Untreated bipolar patients may endure more than ten manic or depressive episodes. Finally, in relation to 10 to 20% of patients, the bipolar disorder will turn into a fast cycle form, either spontaneously or as a result of certain medical treatments. Psychiatrists are now able to initiate various treating strategies which are most likely to be effective as a result of the identification of clinical subtypes of the bipolar disorder. Lithium therapy has been effectively and acutely used for patients with pure or elated mania and its prophylaxis. However, lithium medication may worsen depressive symptoms when used for a long term maintenance therapy. Additionally, mixed mania, rapid cycling type patients and bipolar disorder associated with substance abuse do not respond well to lithium therapy. In addition to the lithium therapy or in place of a lithium therapy, one can report the frequent use of antipsychotic agents in respect of patients with bipolar disorder during both the acute and maintenance phases of treatment. Antipsychotic agents have been used for almost forty years and may be used in combination with a lithium therapy. Conventional antipsychotics are effective but they may induce late dyskinesia, weight gain, sedation, sexual dysfunction and depression. These adverse side effects often lead to non compliance in particular in circumstances where antipsychotic agents are combined with a lithium therapy. A number of alternative somatic treatment approaches have been reported for patients who do not respond well or who are intolerant to lithium therapy. As such, valproate has received regulatory approval for the acute treatment of mania and carbamazepine has been indicated for this condition in a number of countries. Divalproex (Depakote) has recently obtained the authorization to market in France and may be prescribed for manic states or hypomanic states that do not tolerate lithium therapy or for which lithium therapy is contraindicated. A number of other anticonvulsants (lamotrigine, gabapentin and topiramate) are currently being tested. Because of the side effects of the conventional antipsychotic agents, atypical antipsychotic agents are currently on trial and appear to be of interest in the treatment of bipolar disorders. Currently, a number of prospective studies are available with clozapine, risperidone and olanzapine in the treatment of bipolar disorder. Most are short-term studies. Recent randomised, double-blind, placebo-controlled studies have shown clozapine, risperidone and olanzapine to be effective with antimanic and antidepressive effects, both as monotherapy and as add-on maintenance therapy with lithium or valproate. They also have a favorable side effect profile and a positive effect on overall functioning. Similarly, valproate combined with antipsychotics provides greater improvement in mania than antipsychotic medication alone and results in lower dosage of the antipsychotic medication.

However, based on the results of a number of open-label studies, clozapine appears to be effective in relation to schizo-affective and bipolar patients including those with rapid cycling or those who respond inadequately to mood stabilizers, carbamazepine, valproate or conventional antipsychotics. Clozapine seems to be more appropriate for bipolar and schizo-affective patients than schizophrenics. In particular, studies show that patients with manic and mixed-psychotic state of illness are better responders than patients with major depressive syndromes. Four open studies suggest the efficacy of clozapine in the maintenance treatment of bipolar disorder and three prospective, open-label studies show the efficacy of clozapine in the manic state of the illness. However, the number of patients in the studies was not important and these studies are not controlled. Clozapine has also adverse side affects, one of which consisting of a major risk of agranulocytosis and, potentially, death. In addition, clozapine has been shown to produce significant weight gain and sialorrhea as well as significant anticholinergic effects. As a result, clozapine should not be prescribed in the first place. As opposed to clozapine, there are open-label reports and controlled studies in respect of risperidone and olanzapine. Two recent double-blind studies of acute mania found olanzapine to be more effective than placebo. Based on these two studies, olanzapine has recently been approved for the indication of mania. The effects of olanzapine and divalproex in the treatment of mania have also been compared in a large randomized clinical trial. The olanzapine treatment group had significantly greater mean improvement of mania ratings and a significantly greater proportion of patients achieving protocol-defined remission. Significantly more weight gain and cases of dry mouth, increased appetite and somnolence were reported with olanzapine while more cases of nausea were reported with divalproex.

Systematic trials have shown that risperidone may be effective and safe in the treatment of acute mania, as an add-on therapy with lithium or valproate (open studies and two controlled double-blind studies) and as monotherapy (open studies). In an open, multi-center, 6-month study, risperidone seems to be effective and safe as long-term adjunctive therapy in treatment-resistant bipolar and schizo-affective disorders, with no exacerbation of manic symptoms. Risperidone had few adverse side effects (and where there were any, they were mostly mild), mostly consisting of APS and weight gain. A naturalistic comparison of clozapine, risperidone and olanzapine in the treatment of bipolar disorder suggests that the efficacy and tolerability of the three treatments are similar.

Atypical antipsychotics (other than clozapine) are now rated as first-line agents for adjunctive treatment of mania because they produce less adverse side effects. Atypical antipsychotics are also rated as first-line agents for combined treatment of psychotic depression and they are strongly preferred when an antipsychotic is required for long-term maintenance.

Dehydroepiandrosterone (DHEA) and its sulfate ester metabolite (DHEA-S) are precursors to testosterone and, to a lesser extent, to estrogen, and, for both sexes, they are produced in the adrenal cortex. They are among the most abundant steroids in the human body, yet their physiological roles remain unknown. DHEA and DHEA-S appear to have diverse biochemical activities, including actions within the central nervous system. So DHEA is produced in the central nervous system as well as the human adrenals and is present in the brain, concentrated in limbic regions, in levels much higher than other steroids. DHEA has been postulated to function as an excitory neuroregulator, antagonizing g-aminobutyric acid transmission. The main characteristic of DHEA is that its level of concentration in plasma varies throughout life, such level being low during the early childhood and after the age of 60 years. Adrenal production and serum concentrations of DHEA are then known to peak between ages 25 and 30 years and thereafter decrease with age, severe illness and chronic stress. The decrease of DHEA over time would appear to be responsible for morbidity related to aging process. Previous reports have found low levels of DHEA in association with physical and with frailty in the elderly (immunosenescence, increased incidence of osteoporosis, atherosclerosis and cancer, decreased cognitive functions and/or well-being). As it has been touted as a fountain of youth and a sexual tonic and promoted for a variety of illnesses associated with aging, DHEA is widely available over all the United States (since 1994) as a dietary supplement. In France, as a result of a massive advertising campaign, DHEA is already the subject of a widespread use and a growing demand although it has not yet been approved by the relevant authorities for sale as drug to the public. In practice, DHEA is prescribed and delivered under the sole responsibility of both doctor and chemist who ascertain the benefit-risk ratio and the quality of the product. DHEA may then be purchased on the internet or in the form of magistral preparations delivered on the basis of such prescription. Accordingly, there is little information or data on efficacy, drug interactions, results of long-term use, abrupt discontinuation or potential adverse effects related to the use of DHEA. We report a case of mania possibly precipitated by the use of high doses of DHEA (150-200 mg/day at the time of presentation) during several weeks in a 68 years old man who had already been hospitalized for an acute mania many years ago. Although, in this case, the patient suffered a bipolar diathesis in the past, oral DHEA may have played a role in the induction of his acute manic episode. Further research is required to assess the mood effects of DHEA, including its potential risk for patients with bipolar disorder.

Attention deficit, hyperactivity disorder was recently described in adults. The clinical individualization of this syndrome progressed but the categorical approach remains to be entirely completed. The residual form of the childhood disorder does not generate diagnostic problem when childhood previous history is known. ADHD without childhood history refer us to retrospective difficulties of diagnosis and various evolutions of the infantile form linked or not, with other psychiatric pathologies. Etiology remains unknown, hypothesis of an hereditary disfunction of neurotransmitters is the more studied. These patients can benefit from a psychostimulant treatment. Four controlled studies with methylphenidate demonstrated to be significantly superior to placebo. Even if there are methodological difficulties not resolved (comorbidity, homogeneous population) results are encouraging.
