[Association between the violence in the community and the aggressive behaviors of psychotics during their hospitalizations]. / Relation entre la violence intra-hospitalière des patients avec psychoses et la violence dans la communauté.

BACKGROUND: Violence is a common issue in psychiatry and has multiple determiners. The aim of this study is to assess the psychotic inpatients' violence in association with the violence of the neighborhood from which the patients are drawn and to estimate the impact of this environmental factor with regard to other factors. METHOD: A prospective multicenter study was led in nine French cities. Eligible patients were psychotic involuntary patients hospitalized in the cities' psychiatric wards. During their treatments, any kind of aggressive behavior by the patients has been reported by the Overt Aggression Scale (OAS). RESULTS: From June 2010 to May 2011, 95 patients have been included. Seventy-nine per cent of the patients were violent during their hospitalizations. In a bivariate analysis, inpatient violence was significantly associated with different factors: male gender, patient violence history, substance abuse, manic or mixed disorder, the symptoms severity measured by the BPRS, the insight degree and the city crime rate. In a multivariate analysis, the only significant factors associated with the patients' violence were substance abuse, the symptoms severity and the crime rates from the different patients' cities. CONCLUSION: These results suggest that violence within the psychotic patients' neighborhood could represent a risk of violence during their treatments.

Translation and validation of the PREE (Patient Rated Elbow Evaluation) to a French version.

BACKGROUND: Only a few outcome measures specific to elbow pathology and the assessment of their impacts on function are valid and reliable when used in French speaking populations. The English version of the Patient Rated Elbow Evaluation (PREE) was determined to be an optimal candidate for translation. HYPOTHESIS: A French version of the PREE (PREE-Fr) will be generated and compared to its original version in terms of reliability and responsiveness. MATERIALS AND METHODS: The PREE was translated following the guidelines of the American Academy of Orthopedic Surgeons. Patients with a variety of elbow pathologies completed the French version of the PREE (PREE-Fr), the Quick Disabilities of the Arm, Shoulder and Hand (QuickDASH) and the Mayo Elbow Performance Score (MEPS) on three different occasions. The test-retest reliability of the PREE-Fr was calculated using questionnaires that were filled out with a one-week interval between them. The responsiveness was assessed using questionnaires filled out six months after treatment. RESULTS: A French version of the PREE was generated. Data gathered from 54 patients yielded an intra-class correlation coefficient for reliability of 0.89 (CI95%: 0.79-0.94) for the PREE-Fr. For construct validity, using the Pearson correlation coefficient, we obtained excellent correlation between the PREE-Fr and QuickDASH at day one, one week and six months (0.89-0.96) while that between the PREE and MEPS was good to excellent (0.70-0.95). Responsiveness of the PREE-Fr was assessed and yielded a standardized response mean of 1.03, meaning that a large change was recorded between day one and six months. DISCUSSION: The PREE-Fr should be considered in French speaking populations for patients with elbow pathology, whether it is for research or evaluation purposes as it is valid, reliable and responsive to change.

Association of the intronic rs2072621 polymorphism of the X-linked GPR50 gene with affective disorder with seasonal pattern.

This case-control study found an association between Seasonal Affective Disorder (SAD) and a single nucleotide polymorphism (intronic rs2072621) of the gene encoding GPR50 (an orphan member of the G protein-coupled melatonin receptor subfamily) in females. This may represent a gender-specific risk factor and a molecular link between melatonin and SAD.

[Milnacipran and venlafaxine at flexible doses (up to 200 mg/d) in the outpatient treatment of adults with moderate-to-severe major depressive disorder: a 24-week randomised, double blind exploratory study]. / Milnacipran et venlafaxine à posologie flexible (jusqu'à 200 mg/j) dans le traitement ambulatoire des épisodes dépressifs majeurs modérés à sévères de l'adulte: étude exploratoire de 24 semaines, randomisée en double insu.

INTRODUCTION: Serotonin (HT) and noradrenaline (NA) reuptake inhibitors (SNRIs) are commonly used as first line treatment of major depressive disorders (MDD). As compared to tricyclic antidepressants, they have proved similar efficacy and better tolerability. Milnacipran (MLN) (Ixel) and venlafaxine (VLF) (Effexor) are two SNRIs pharmacologically differing by their NA/HT ratio of potency: 1:1 and 1:30, respectively. OBJECTIVES: To investigate the efficacy and safety/tolerability of MLN and VLF administered at flexible doses (100, 150 or 200 mg/day) for 24 weeks (including 4 weeks of up-titration) in the outpatient treatment of adults with moderate-to-severe MDD. DESIGN: Multicentre, randomised, double blind, 2-parallel-arm, 24-week exploratory trial conducted in France by 50 psychiatrists. DIAGNOSIS AND MAIN INCLUSION CRITERIA: Male or female outpatients, aged 18 to 70, meeting the DSM-IV-TR and related MINI criteria for recurrent, unipolar, moderate-to-severe MDD, with neither psychotic features nor severe suicidal risk. A Montgomery-Asberg depression rating scale (MADRS) score> or =23 was required at inclusion. TREATMENT SCHEDULE: Patients were randomised to receive either MLN or VLF (1:1 ratio) for 24 weeks in double-blind conditions. Regardless of the treatment received, the following dosing schedule was applied: during the initial 4-week up-titration phase, the dosage was progressively increased from 25 mg/day (qd administration) to 150 mg/day (bid administration). At week 4, the dosage was either maintained at 150 mg/day, or adapted to 100 or 200 mg/day, based on the investigator's clinical judgement. At any time during the 20 following treatment weeks, the dose could be lowered for safety concerns until a minimal threshold of 100 mg/day. From Week 24, the dosage was decreased by 50mg/day every five days. After randomisation, eight assessment visits were organised at 2, 4, 6, 8, 12, 18, 24 weeks, and at study end (after the 5-15 days of down-titration and 10 days free of treatment). Efficacy evaluation ratings included the MADRS and global disease severity (CGI-S) total scores. Rates of MADRS response (reduction of initial score> or =50%) and remission (score< or =10) were calculated at Week 8 and Week 24 in the full analysis set as well as in the subgroups of patients with depressive disorder of severe DSM-IV intensity and with a MINI evaluation of suicidal risk (rated as required 'moderate' at the worst). STATISTICAL ANALYSIS: Standard distribution statistics (including mean and standard deviation [S.D.]) of scores and their changes from baseline, were calculated using the observed-case (OC) approach at all assessment times for the MADRS score, and the last-observation-carried-forward (LOCF) at 8 and 24 weeks for both MADRS and CGI-S scores. MADRS response and remission rates at 8 and 24 weeks were calculated using the LOCF approach by normal approximation of the binomial distribution. Bilateral exploratory statistical tests at 5% significance level were performed for results at 8 and 24 weeks of: (i) MADRS score changes from baseline, based on the score progress at each visit (mixed model for repeated measurements [MMRM]), and (ii) global MADRS response and remission rates (Chi(2)). RESULTS AND PATIENTS: A total of 195 patients were randomly assigned MLN (n=97) or VLF (n=98) and 134 (68.7%: 61.9%/MLN and 75.5%/VLF) completed the trial. At the end of the up-titration, patients received 100 mg/day (11.4%/MLN, 10%/VLF), 150 mg/day (30.4%/MLN, 43.8%/VLF), or 200 mg/day (58.2%/MLN, 46.3%/VLF). Totals of 177 patients (90/MLN and 87/VLF) and 181 patients (90/MLN and 91/VLF) were analysed for efficacy and safety, respectively. Treatment groups were similar for baseline characteristics except a higher proportion of MLN patients with a severe depressive episode (63.3% versus 54%). RESULTS AND EFFICACY: MADRS score (mean [S.D.] initial score: 31 [4.5]) progressively decreased all along the treatment course and similarly in both groups (Week 8-OC : -18.8 [7.7]/MLN and -18.6 [7.3]/VLF, p(MMRM)=0.95 ; Week 24-OC : -23.1 [7.8]/MLN and -22.4 [7.3]/VLF, p(MMRM)=0.37 ). At week 8-LOCF, MADRS response rates were similar in both groups (64.4%/MLN, 65.5%/VLF, p(chi2)=0.88) as well as remission rates (42.2%/MLN, 42.5%/VLF p(chi2)=0.97). At week 24 they remained non clinically and statistically different between groups (response rates: 70%/MLN, 77%/VLF, p(chi2)=0.29; remission rates: 52.2%/MLN, 62.1%/VLF, p(chi2)=0.19). In both "severe depressive episode" and "MINI mild or moderate suicidal risk" subgroups (n=104 and 75, respectively), response and remission rates were non clinically different at both time points, however in the "MINI mild-to-moderate suicidal risk" subgroup, MLN tended to be more rapidly active (remission rate at week 8-LOCF: 44.7%/MLN, 35.1%/VLF). The changes in CGI-S were also indicative of a significant improvement of the global illness severity with both treatments. RESULTS AND SAFETY/TOLERABILITY: The tolerability profile of both drugs was in line with their pharmacological activity. About 70% of patients in both groups experienced at least one adverse event (AE). In both groups, the most common AEs were nausea, dizziness, headache and hyperhidrosis, and, in the male patients, genito-urinary problems: orgasmic disorders (VLF only) and dysuria (MLN only). These AEs were mostly responsible for definitive treatment discontinuation for tolerability concerns. None of the 6 serious adverse events (SAEs) on MLN and 4 of the 8 SAEs on VLF were related to the test drug. CONCLUSION: MLN and VLF at flexible doses up to 200 mg/day globally exhibited similar efficacy and tolerability profiles in the long-term treatment of adults with MDD.

Preattentional processes and disorganization in schizophrenia: Influence of a 6-week risperidone treatment.

INTRODUCTION: Visual orientation and attention are impaired in schizophrenia. Engagement and disengagement of attention and the ability to prompt responses to a stimulus in patients before and after six weeks of risperidone were compared to controls. METHODS: Ten unmedicated (nine naïve) schizophrenic patients, and eleven controls performed 1) A visual orienting task, the Cued Target Detection task (CTD), with the detection of a visual stimulus in valid, invalid, no cue and double cue trials, two conditions for fixation offset for a modulation of visual fixation: Gap: 200 ms before target; No Gap: simultaneous with target, 2) Choice Reaction Time (CRT 0.5 and 2 s delays). RESULTS: At baseline, patients showed longer RT than controls in CRT, but not in CTD, with in CTD, no facilitation of RT with the gap procedure. The alertness index was almost null in CTD-Gap and comparable to controls in CTD-No Gap. Efficiency to detect attended stimuli (CTD-No Gap) and warning effect (CRT 0.5 s) were negatively correlated to disorganization. After treatment, readiness to act in CRT had decreased. In CTD-No Gap, change in PANSS disorganization was correlated to an increased validity index, change in negative sub-score was correlated to decreased attention cost. CONCLUSION: Untreated patients displayed a deficit of Gap effect and a slowing in sustained attention. Disorganization interfered with warning and visual detection. After treatment, its improvement and negative symptoms improvement were associated with better visual detection. These alterations in visual orienting provide new evidence for an oculomotor dysregulation of attentional engagement in schizophrenia.

(AAT)n repeat in the cannabinoid receptor gene (CNR1): association with cocaine addiction in an African-Caribbean population.

Owing to their agonist action on dopaminergic systems, cannabinoids may play a major role in substance dependency and schizophrenia. We examined the (AAT)n triplet repeat polymorphism nearby the CNR1 gene, which encodes human cannabinoid (CB1) receptor, in a male Afro-Caribbean population. The allelic and genotypic distributions were significantly different in non-schizophrenic cocaine dependents (n = 97), schizophrenic cocaine dependents (n = 45) and matched controls (n = 88) (P < 10(-4)). The frequency of the (AAT)12 repeat allele was increased in non-schizophrenic cocaine dependents and schizophrenic cocaine dependents vs controls (25.3 and 26.7 vs 5.7%) (P < 10(-4)). Our results support that the (AAT)n polymorphism nearby the CNR1 gene could be associated with predisposition to cocaine dependency.

Effects of lithium on saccadic eye movements in healthy subjects in a ten-day double-blind placebo-controlled cross-over pilot study.

INTRODUCTION: Although previous studies have shown that lithium modifies eye movements or psychomotor speed, no studies have ever explored the predictive saccades or memory guided saccades during lithium administration. We took the objective to determine the influence of lithium in pseudo-random, predictive or memory-guided saccades in healthy subjects with a view to detect reduced psychomotor speed, inability to anticipate incoming events, or working memory deficits. METHODS: A ten day lithium-placebo randomized double-blind cross-over pilot study was carried out with 12 healthy male volunteers. The cognitive assessment included pseudo-random, predictive and memory guided saccades before and after lithium and placebo periods. A biological assay substantiated the lithium effect on TSH and thyroid hormones. RESULTS: There was no change in pseudo-random or memory guided saccades when comparing lithium or placebo administration. However the ratio of anticipated saccades decreased under the lithium sequence while it remained stable under placebo. Also, subjects having lithium serum levels of > 0.5 meq/l had longer latencies in anticipated saccades. CONCLUSION: The findings do not support a major effect of lithium on alertness or on working memory, although the dosage and duration of lithium was sufficient to modify TSH blood level. Nevertheless, lithium treatment was associated with decreased anticipation in predictive saccades, suggesting this could reflect a reduced ability to anticipate quick motor movements and could be related to the well-known effect of lithium as an anti-impulsive medication.

[Visuospatial context processing in untreated schizophrenic patients and relation to disorganization syndrome]. / Traitement du contexte visuospatial chez des patients schizophrènes non traités -- influence de la désorganisation.

AIM: Previous studies on schizophrenia have suggested that context-processing disturbances were one of the core cognitive deficits present in schizophrenia. Schizophrenic patients have a failure either of inhibition strategy and maintenance of visuospatial information (25) in condition of contextual interference. In the present study, we explored the performances of untreated schizophrenic patients with 2 tasks exploring detection and long term retention of complex visual features and field dependence-independence tasks were selected. These abilities involve temporary maintenance of visuospatial information and executive functioning of visual working memory system. Several studies have shown that cognitive deficit may depend on schizophrenic symptomatology. However results remain controversial in determining the specific influence of negative and positive symptomatologies as well as clinical disorganization. Our goal was to explore the processing of spatial context and its relation to disorganized syndrome. This study was approved by the local ethic committee. METHODOLOGY: Thirty-six schizophrenic patients were included according to DSM IV criteria (19 neuroleptic naïve, 17 unmedicated patients during more than 3 months). Thirty-six healthy controls were matched to patients for age, gender and level of education. Absence of axis 1 pathology was attested for controls with SCID-NP. Current symptomatology was evaluated by the Positive and Negative Syndrome Scale (PANSS) (14). Clinical disorganisation was evaluated with the disorganisation score established upon a factorial analysis of PANSS by Lepine and Lançon. Items selected to distinguish the disorganised group were abstraction, disorganization, orientation, and attention. PROCEDURE: Two tasks of embedded figures were administered individually to patients and controls. The Faverge task (Research of Figures-RF) (10) evaluates the ability to recognize the target from spatial complex geometrical figures. The Group Embedded Figure Task (GEFT - Oltman) assesses the detection and maintenance of visual target and its recognition within a complex figure. Performance between patients and controls were compared with the Student T test. The comparison of two clinical subgroups of disorganized and low disorganized patients and control group was performed with an ANOVA. Tuckey test was used for pairwise comparisons. RESULTS: We defined two subgroups of patients, disorganized patients (subscore 12, n=17) and low disorganized patients (subscore<12, n=19). Theses 2 subgroups were similar for age and level of education. Concerning the two tasks, there was no significant difference between schizophrenic patients and normal controls. The comparison between subgroups of disorganized and low disorganized patients, for RF task, showed a decrease of correct answers with disorganized patients (p<0.05). For GEFT task, disorganized patients had a decrease of correct answers p<0.01) and more errors (p<0.01) and omissions (p<0.05). The low disorganized patients exhibited for the two tests comparable performance to controls. The disorganized patients had a decrease of right answers (p<0.05) and more errors (p<0.05) than controls for GEFT task and no significant difference for RF. However, with IQ (evaluated with an abstract reasoning test) introduced as covariate, only correct answers for GEFT task remain significant (p<0.05). DISCUSSION: The weak performance of disorganized schizophrenic patients for two tasks RF and GEFT showed that treatment of visuospatial information was impaired in the first perceptive phase of selection and in the organization of information (RF), especially with the maintenance of visual information in memory (GEFT). By contrast, low disorganized patients demonstrated a correct analytic treatment of elementary processing and visuospatial working memory. CONCLUSION: The severity of disorganization influences the visuospatial context processing and visuospatial working memory. These results show the heterogeneity of cognitive functioning regarding to schizophrenic symptomatologies. This difficulty could be related to a problem of central executive functioning in the visuospatial component of working memory, possibly mediated by the dysfunction of dorsolateral prefrontal cortex.

[Personality tests and gender identification in male transsexuals]. / Tests de personnalité et identification sexuée chez des transsexuels masculins.

The aim of this research project was to study gender identification in male transsexuals compared to male and female controls, using the Rorschach test and the MMPI. In the international literature, many researches have shown that the nature of the human response on Rorschach card III is linked to gender identification, as is the MMPI Mf scale. Ten untreated male homosexual transsexuals and 18 treated and operated male homosexual transsexuals were compared to 10 male and 12 female controls regarding verbal IQ, human content on Rorschach card III and the MMPI Mf scale. Absence of hormonal treatment for the first group of transsexuals was checked by a blood test at the time of the psychological testing. Responses on Rorschach card III were scored according to different kinds of human contents: male (M), female (F), gender-unidentified/neutral (N), bisexual (B), feminine then masculine or the opposite (M/F), and nonhuman (NH). N, B, M/F and NH responses were rare in all Rorschach protocols. As expected, responses given by participants in the control group were significantly more consistent with their anatomical sex than with the opposite sex. Untreated transsexuals do not differ from treated and operated transsexuals on Rorschach data, and both transsexual groups give significantly more female human representations than male controls. Transsexuals' results are similar to female controls. Untreated transsexuals' mean score on the MMPI Mf scale is significantly higher than that of treated and operated transsexuals' score, in the male profile (biological sex). Both groups of transsexuals score higher on the Mf scale in the male profile than in the female profile. The mean Mf score in the male profile is significantly higher than that of male controls, whereas, in the female profile, the mean Mf score is similar to that of female controls. This study shows that for both groups of transsexuals, results are homogenous in respect of Rorschach and MMPI, showing hyper-conformism to self-perceived gender. Results in both groups are similar to results of female controls, but tend to show even more feminine gender identification. The absence of any significant difference between untreated and treated and operated transsexuals seems surprising, suggesting that the hormonal treatment has not had a major impact on gender identification processes. It would doubtless be interesting to study gender identification using even more kinds of data: all human contents in the Rorschach protocol (not just the responses given to card III), MMPI Mf scale, Draw-A-Person Test and Animal-and-Opposite Drawing Test. This would enhance result liability and could provide useful information about how gendter identification processes evolve after surgical sex reassigment.

[Assessment of metabolic impairments inducted by atypical antipsychotics among schizophrenic patients]. / Evaluation des troubles du métabolisme induits par les antipsychotiques atypiques chez les patients schizophrènes.

Conventional and atypical antipsychotics are known to induce weight gain, cause glucose and lipid impairments among schizophrenic patients. These impairments contribute to the intrinsic risk factors linked to the psychiatric pathology (sedentary state, nicotin addiction, diabetes) increasing numbers of cardiovascular complications. We propose to study ponderal modifications and presence of metabolic abnormalities in a population of schizophrenic patients treated by conventional or atypical antipsychotics, depending on the received treatment; 32 patients, whose schizophrenia diagnosis had been previously made, were consecutively included over a 4 months period. They were divided into three groups: patients treated by conventional antipsychotics (n = 6), by atypical antipsychotics (n = 16) or by a combination of both (n = 10); 6 patients (18%) display overweight problems, 4 patients (12.5%) got hypertriglyceridemia and 4 other patients (12.5%) have hypercholesterolemia. No particular drug could be directly targeted, partly because of the restricted size of our sample, but the patients presenting metabolism impairment were treated by atypical antipsychotic. The observance of these abnormalities is reflected in publications and lead to some antipsychotic treatments monitoring rules.

Antidepressant efficacy and cognitive effects of repetitive transcranial magnetic stimulation in vascular depression: an open trial.

BACKGROUND: Beneficial effects of repetitive transcranial magnetic stimulation (rTMS) were demonstrated by many controlled studies in major depression. Moreover, this promising and non invasive therapeutic tool seems to be better tolerated than electroconvulsive therapy.Vascular depression is a subtype of late-life depression, associated with cerebrovascular disease and means a poorer response to antidepressant treatment. We employed rTMS over the left prefrontal cortex in 11 patients with late-onset resistant vascular depression. The primary purpose of this two-week open study was to examine antidepressant efficacy of rTMS in vascular depression. The secondary aim was to evaluate cognitive effects of rTMS in our sample. METHODS: Clinical status, as measured with the Hamilton Depression Rating Scale (HDRS), and cognitive effects, as evaluated by neuropsychological tests, were assessed at baseline and after two weeks of rTMS. Brain measurements to obtain an index of prefrontal atrophy were performed at both the motor cortex and prefrontal cortex. RESULTS: Five out of 11 resistant patients with late-onset vascular depression were responders. They showed a clinically meaningful improvement in HDRS scores, with a decrease of 11, 4 points (p<0.01). Antidepressant response is correlated to the relative degree of prefrontal atrophy (p = 0.05). After two weeks, verbal fluency and visuospatial memory improved. No cognitive performance deteriorated except for verbal memory, as the delayed recall decreased significantly in the responders' group. CONCLUSIONS: Our preliminary observations prompt to perform a subsequent controlled study to examine if rTMS may constitute an alternative to electroconvulsive therapy.

Double-blind comparative study of the action of repeated administration of milnacipran versus placebo on cognitive functions in healthy volunteers.

OBJECTIVE: The principal objective was to compare the effects of milnacipran, an antidepressant characterized by a dual-action on serotonin and noradrenaline reuptake, with placebo on memory, attention and psychomotor performance in healthy volunteers. The secondary objective was to evaluate the effects of milnacipran on mood, anxiety and vigilance in these subjects. METHODS: In a double-blind crossover randomized trial, milnacipran (50 mg b.d.) or placebo was administered during two periods of 7 days separated by a washout period of 7 days. Memory tests (recall of words, images and coloured bars), tests to evaluate attention and vigilance (squares test, critical flicker fusion test and choice reaction time test) and visual analogue scales for affect and sleep were used. RESULTS: There were no significant differences between milnacipran and placebo groups with respect to the psychomotor functions tested. No differences were observed in the Norris scales for vigilance, anxiety or satisfaction or in the sleep questionnaire (sleep latency, sleep quality and waking). CONCLUSION: Milnacipran, administered at 100 mg per day for 7 days to healthy volunteers, had no effects on cognitive functions.

[Comparison of two assessment tools of antidepressant side-effects: UKU scale versus spontaneous notification]. / Comparaison de deux outils de mesure des effets indésirables d'un traitement antidépresseur: la notification spontanée et l'échelle UKU.

BACKGROUND AND AIM OF THE STUDY: Overall, the efficacy of the newer antidepressants: serotonin selective reuptake inhibitors (SSRI), selective serotonin/norepinephrine reuptake inhibitor (SNRI), noradrenergic and specific serotonergic antidepressant (NaSSA) and tianeptine is similar to that of the tricyclics, and so their acceptability/safety becomes a selection criterion for the clinician. However, side-effect assessment comes up against several difficulties: distinguishing between somatic symptoms caused by the depression and those caused by the treatment -- which assessment tool to use (spontaneous notification, standardized scales that are not specific for the side effects caused by psychotropic drugs, standardised scales specific for the side effects caused by psychotropic drugs, meta-analysis, etc.) -- which data sources to consult (anecdotal reports, reviews, prospective studies), and which data set to use, etc. As a result, the question of the exhaustiveness and reliability of the data consulted by the clinician can arise. We therefore conducted a comparative study in patients treated with these newer antidepressants, of 2 antidepressants side-effect assessment tools: spontaneous notification (SN) versus the UKU scale, a standardised scale specific for the side effects of psychotropic drugs. METHODOLOGY: The depressed outpatients were selected from a psychiatric unit in a French psychiatric hospital and from a non-hospital consulting room. The main inclusion criteria were: male or female subjects, suffering from major depression without melancholia or psychotic features or suffering from mood disorders (according to DSM IV criteria), who had been treated for at least 4 weeks with one of the newer antidepressants. The main exclusion criteria were: any other psychiatric disorder, a serious physical disorder, treatment with neuroleptics, mood-changing drugs or other antidepressants, and patients who were not able to understand the questionnaire. The investigation was carried out by a clinical pharmacist. RESULTS: Fifty patients were included in the study. There were 18 men and 32 women. The mean age was 53.5 15.9 years [22 - 77], the mean period of treatment was 24 30.5 months [1 - 127] and 52% of the patients received concomitant medication with anxiolitic or hypnotic drug(s). The percentage of patients who reported at least one side effect was significantly higher for the UKU scale than for SN (84% vs 58%, p<0.01). The ratio between SN and UKU scale scores was 2/3. A similar pattern was found for the total number of side effects (n=177 vs n=47, p<0.001). The ratio between the total number of side effects for the SN and UKU scale was 1/4. The side effects were divided into five subgroups: psychiatric, neurovegetative, sexual, neurological and others. In all these subgroups, the number of side effects reported was significantly higher when the UKU scale was used than when SN was used. The values were as follows: psychiatric (n=44 vs n=15, p<0.001), neurovegetative (n=59 vs n=15, p<0.001), sexual (n=36 vs n=10, p<0.001), neurological (n=11 vs n=2, p<0.001) and other side effects (n=27 vs n=5, p<0.001). Nineteen side effects were only reported when SN was used (for example: dry eyes, incompatibility with alcohol, euphoria...). Twenty-four side effects were only reported when the UKU scale was used (for example: increased libido, loss of bodyweight...). The side effects had no impact on daily life in most of 80% of the patients; there was no significant difference between the patient's assessment of the discomfort caused by side effects and the clinician's assessment. In 90% of cases, the side effects did not lead to any change in the treatment. DISCUSSION: The findings of this study show that the collection of data regarding side effects depends on the assessment tool used: the number of side effects reported was significantly higher when the UKU scale was used than when SN was used. However, this finding must viewed with caution, because it has been showed that checklists can induce symptoms in suggestible patients. Neurovegetative troubles are the most commonly reported side effects, and neurological troubles the least often reported. This matches the tolerability profile of these antidepressants. The disorders that were least frequently spontaneously reported were the neurological, sexual and "other" side effects. These emerged only when the clinician asked the patient about them. The 19 side effects that were only reported when SN was used were side effects that were not included in the UKU scale or that had not been present during the three days before we started the investigation. The 34 side effects that were only reported when the UKU scale was used were either side effects with no apparent link with the treatment (for example: micturition troubles) or embarrassing effects (such as increased libido). CONCLUSION: Our findings show that the collection of data on side effects depends on the assessment tool used. These findings need to be confirmed by large-scale comparative studies, and the standardization of the assessment of side effects is a question that needs to be raised.

5HTTLPR polymorphism in schizophrenic patients: further support for association with violent suicide attempts.

Previous studies testing the functional polymorphism in the promoter of the serotonin-transporter gene (5HTTLPR) in various psychiatric conditions have suggested that the association could be with an intermediate phenotype, impulsivity and/or violence rather than with a diagnosis. Schizophrenia is associated with a high risk of suicide, especially in patients with high impulsivity. We examined whether this polymorphism could be associated with violent suicide and/or impulsivity in schizophrenic patients. We genotyped the 5HTTLPR polymorphism in 185 unrelated schizophrenic patients from a French Caucasian population. The genotype frequencies significantly differed between patients who made violent suicide attempts and both, those who attempted suicide with a non-violent method (P = 0.013) and those who never attempted suicide (P = 0.026). The genotypes containing the low activity "short" allele was significantly more frequent in violent suicide attempters (P = 0.007) than in non-violent suicide attempters. No evidence was found for an association either with schizophrenia itself, when compared to gender and ethnically matched controls (n = 159) or with impulsivity, assessed using Barratt's Impulsivity Scale. Although replication studies are warranted, these results in schizophrenia further support the hypothesis that 5HTTLPR polymorphism is a risk factor for violent suicidal behavior.

[Predictive factors of response to buprenorphine in the substitutive treatment of heroin addicts. Results of a multicenter study of 73 patients]. / Facteurs prédictifs de la réponse à la buprénorphine en traitement substitutif des héroïnomanies. Résultats d'une étude multicentrique sur 73 patients.

OBJECTIVE: Buprenorphine has a partial morphine-agonist pharmacological profile. It is proposed as alternative to methadone in opiate drug addicts with greater safety of use and less cost in terms of public health. The aim of this study was to determine the clinical factors of response to this molecule. METHOD: The study was conducted in 73 patients treated for 3 months with adaptable doses. Mean dose was 8.5 mg/d (range: 3 to 16 mg/d). Response to treatment was defined as: still in the study at 3 months and absence of opiates in 75% of urinary samples over the past month. RESULTS: Forty-eight patients responded and 25 did not. The determinating clinical variables of response were: opiate drug addiction less than 10 years, high score on the Addiction Severity Index (ASI), absence of depression according to the Minnesota Multiphasic Personality Inventory (MMPI) and low rate of disinhibition on Zukerman's sensation seeking scale. Conversely, the dose of buprenorphine within the limits specified in the Marketing Authorisation did not intervene in the response. CONCLUSION: In view of its partial agonist effect, administration of buprenorphine must be reserved for patients addicted to opiates for less than 10 years, non-depressive and with low disinhibition on Zukerman's scale.

[French validation of a Minor Morphologic Anomalies Scale in schizophrenic patients and their parents]. / Validation française d'une échelle d'Anomalies Morphologiques Mineures appliquée à des patients schizophrènes et à leurs parents.

UNLABELLED: Minor Physical Anomalies represent valuable indices of disturbance in early neurodevelopment. They are frequently observed in individuals with various brain disorders, including mental retardation, autism, epilepsy, hyperactivity, foetal alcohol syndrome and schizophrenia. The high prevalence of Minor Physical Anomalies in schizophrenia provides considerable support for a neurodevelopmental model in this disorder. However, studies in large sample using standardised scale are lacking. Such studies are needed in order to confirm their actual frequency and study the clinical correlates or morphological anomalies. OBJECTIVE: The aim of this study was to revise and validate a French version of a scale designed for the evaluation of Minor Physical Anomalies in adult psychiatric patients and notably in patients with schizophrenia. METHODOLOGY: The scale was revised from the Waldrop scale. The choice of items was done on the basis of frequency, reliability in the adult, reliability of rating. Some new items, related to know syndroms with comportmental symptoms were added. Both raters had previously had a short initiation to the rating of the scale. Interrater reliability between two examiners, blind with regards to the diagnosis was evaluated. RESULTS: The interrater reliability was good, with an intraclass correlation coefficient at 0.97. Patients had significantly more minor physical anomalies than comparison subjects, and also more Minor Physical Anomalies than their parents. Fathers and mothers of these schizophrenic patients had significantly more Minor Physical Anomalies than normal comparison subjects. CONCLUSION: Although the evaluation of physical anomalies relies on subjective appreciation of normal vs abnormal, the revised version of minor physical anomalies scale (French version) was found to be a reliable tool, provided that a short initiation to the rating is performed. The scale differentiated schizophrenic patients from their parents, and the latter from the normal controls. A lot of questions remains unanswered concerning the neurodevelopmental hypothesis of schizophrenia. This scale appeared as a useful complementary tool to help in the determination of the developmental phenotypic status of the patients enrolled in pathophysiological studies aiming the identification of developmental factors in schizophrenia.
