Abstract
Gastric heterotopia is characterized by the presence of mature gastric tissue outside the stomach, yet its occurrence in the palate has not been previously documented. We describe a case of gastric heterotopia in the hard palate of an elderly female patient, presenting as a swollen mass with associated secretion. Given the patient's age and clinical symptoms, a presumptive diagnosis of a malignant tumor originating from the minor salivary glands was made. An incisional biopsy of the mass revealed gastric heterotopia. Subsequently, the extended excision of the lesion was performed, leading to the full resolution of the patient's symptoms. After a two-year follow-up period, no evidence of recurrence was observed. The importance of this case, underscored by the unprecedented location of gastric heterotopia, emphasizes the critical need for thorough evaluation to avert misdiagnosis, as well as the complete surgical excision of the lesion to prevent recurrence.

Abstract
Eagle syndrome is a rare disease characterised by symptoms associated with an elongated styloid process or calcification of the stylohyoid and stylomandibular ligament. Symptoms associated with Eagle Syndrome include orofacial and cervical pain, dysphagia, and pharyngeal foreign body sensation. Additionally, it can present with cerebrovascular symptoms due to the compression of adjacent neurovascular structures within the vicinity of the styloid process during rotation and extension of the neck. This report presents the case of a 33-year-old male with bilateral elongated styloid processes in whom the only symptom referred was recurrent syncope. The diagnosis was made years after the initial complaints and after several observations and imagings performed by different specialities. Surgical resection of the elongated process by the cervical approach was the treatment of choice. In patients with cerebrovascular symptoms, principally those induced by positional changes of the neck, Eagle syndrome should be considered in the differential diagnosis.

Abstract
Leveraging the differential response of genes to mechanical loading may allow for the identification of novel therapeutics and we have recently established placental growth factor (PGF) as a mechanically augmented gene which promotes angiogenesis at higher doses and osteogenesis at lower doses. Herein, we sought to execute a mechanobiology-informed approach to regenerative medicine by designing a functionalized scaffold for the dose-controlled delivery of PGF which we hypothesized would be capable of promoting regeneration of critically-sized bone defects. Alginate microparticles and collagen/hydroxyapatite scaffolds were shown to be effective PGF-delivery platforms, as demonstrated by their capacity to promote angiogenesis in vitro. A PGF release profile consisting of an initial burst release to promote angiogenesis followed by a lower sustained release to promote osteogenesis was achieved by incorporating PGF-loaded microparticles into a collagen/hydroxyapatite scaffold already containing directly incorporated PGF. Although this PGF-functionalized scaffold demonstrated only a modest increase in osteogenic capacity in vitro, robust bone regeneration was observed after implantation into rat calvarial defects, indicating that the dose-dependent effect of PGF can be harnessed as an alternative to multi-drug systems for the delivery of both pro-angiogenic and pro-osteogenic cues. This mechanobiology-informed approach provides a framework for strategies aimed at identifying and evaluating novel scaffold-based systems for regenerative applications.

Abstract
Background People suffering from schizophrenia cannot easily access employment in European countries. Different types of vocational programs coexist in France: supported employment, sheltered employment (ShE), and hybrid vocational programs. It is now acknowledged that the frequent cognitive impairments constitute a major obstacle to employment for people with schizophrenia. However, cognitive remediation (CR) is an evidence-based nonpharmacological treatment for these neurocognitive deficits. Methods RemedRehab was a multicentric randomized comparative open trial in parallel groups conducted in eight centers in France between 2013 and 2018. Participants were recruited into ShE firms before their insertion in employment (preparation phase). They were randomly assigned to cognitive training Cognitive Remediation for Schizophrenia (RECOS) or Treatment As Usual (TAU). The aim of the study was to compare with the benefits of the RECOS program on access to employment and work attendance for people with schizophrenia, measured by the ratio: number of hours worked on number of hours stipulated in the contract. Results Seventy-nine patients were included in the study between October 2018 and September 2019. Fifty-three patients completed the study. Hours worked / planned hours equal to 1 or greater than 1 were significantly higher in the RECOS group than in the TAU group. Conclusions Participants benefited from a RECOS individualized CR program allows a better rate of work attendance in ShE, compared to the ones benefited from TAU. Traditional vocational rehabilitation enhanced with individualized CR in a population of patients with schizophrenia is efficient on work attendance during the first months of work integration.

Abstract
Core-shell scaffolds offer a promising regenerative solution to debilitating injuries to anterior cruciate ligament (ACL) thanks to a unique biphasic structure. Nevertheless, current core-shell designs are impaired by an imbalance between permeability, biochemical and mechanical cues. This study aimed to address this issue by creating a porous core-shell construct which favors cell infiltration and matrix production, while providing mechanical stability at the site of injury. The developed core-shell scaffold combines an outer shell of electrospun poly(caprolactone) fibers with a freeze-dried core of type I collagen doped with proteoglycans (biglycan, decorin) or glycosaminoglycans (chondroitin sulphate, dermatan sulphate). The aligned fibrous shell achieved an elastic modulus akin of the human ACL, while the porous collagen core is permeable to human mesenchymal stem cell (hMSC). Doping of the core with the aforementioned biomolecules led to structural and mechanical changes in the pore network. Assessment of cellular metabolic activity and scaffold contraction shows that hMSCs actively remodel the matrix at different degrees, depending on the core's doping formulation. Additionally, immunohistochemical staining and mRNA transcript levels show that the collagen-chondroitin sulphate formulation has the highest matrix production activity, while the collagen-decorin formulation featured a matrix production profile more characteristic of the undamaged tissue. Together, this demonstrates that scaffold doping with target biomolecules leads to distinct levels of cell-mediated matrix remodeling. Overall, this work resulted in the development of a versatile and robust platform with a combination of mechanical and biochemical features that have a significant potential in promoting the repair process of ACL tissue.

Abstract
OBJECTIVE Although lithium is widely used in current practice to treat bipolar disorder (BD) and treatment-resistant major depressive disorder (MDD) among older adults, little is known about its efficacy and tolerability in this population, which is generally excluded from randomized clinical trials. The objective of this study was to evaluate the efficacy and tolerability of long-term use of lithium among older adults with BD and MDD. METHOD Data from the Cohort of individuals with Schizophrenia and mood disorders Aged 55 years or more (CSA) were used. Two groups of patients with BD and MDD were compared: those who were currently receiving lithium versus those who were not. The effects of lithium on psychiatric (i.e., depressive symptoms severity, perceived clinical severity, rates of psychiatric admissions in the past-year), geriatric (overall and cognitive functioning) and physical outcomes (i.e., rates of non-psychiatric medical comorbidities and general hospital admissions in the past-year) were evaluated. All analyses were adjusted for age, sex, duration of disorder, diagnosis, smoking status, alcohol use, and use of antipsychotics, antiepileptics or antidepressants. RESULTS Among the 281 older participants with BD or MDD, 15.7% were taking lithium for a mean duration of 12.5(SD = 11.6) years. Lithium use was associated with lower intensity of depressive symptoms, reduced perceived clinical global severity and lower benzodiazepine use (all p < 0.05), without being linked to greater rates of medical comorbidities, except for hypothyroidism. LIMITATIONS Data were cross-sectional and data on lifetime history of psychotropic medications was not assessed. CONCLUSION Our results suggest that long-term lithium use may be efficient and relatively well-tolerated in older adults with BD or treatment-resistant MDD.

Abstract
INTRODUCTION Bronchogenic cysts are rare malformations, mostly diagnosed in children. We report the rare case of a neck bronchogenic cyst diagnosed in an elderly patient. PRESENTATION OF CASE The patient complained of a long-standing submental mass. The diagnostic work-up resulted in a thyroglossal duct cyst diagnosis for which the patient underwent a Sistrunk procedure. However, the histological analysis of the lesion ultimately revealed a bronchogenic cyst. DISCUSSION Neck bronchogenic cysts are rare and, in adults, normally asymptomatic. Imaging exams can suggest the diagnosis but they are most important for surgical planning. Surgery is the elected treatment for bronchogenic cysts and the histopathologic exam of the specimen provides definitive diagnosis. CONCLUSION This case demonstrates than even though they are a rare diagnosis, bronchogenic cysts should be considered in the diagnostic work-up of neck cysts, even in elderly patients.

IntroductionThe relationship between brain tumours, temporal epilepsy and psychiatric symptoms are historically known.ObjectivesTo report a case of mania in a patient with previous diagnosis of bipolar disorder, temporal tumour and temporal epilepsy.MethodsClinical records. Research on PubMed, using “lateral temporal epilepsy” or “brain tumour” and “mania”.ResultsA 52 years old man was conducted to the emergency department by the police. He was found with psychomotor agitation at the Sanctuary of Fátima. He was apparently hyperthimic with flight of ideas. He had a history of epilepsy and temporal tumour and two previous manic episodes. It was assumed as a maniac episode.During inpatient evaluation, patient had memory for the occurrence. He described a sudden onset on the day before, after drinking wine. He described delirant atmosphere, persecutory and mystic delusional beliefs “this is the third secret of Fátima being revealed”, followed by ecstasy and psychomotor agitation. Remission was obtained in one week on psychotropics. MRI documented the lesion. Electroencephalography performed one month later revealed “slow waves.”ConclusionsOrganic causes should be excluded before consider a psychiatric disorder. The hypothesis of epilepsy-related psychosis or mania and other effects of a temporal tumour should be considered in etiology. However, co morbidity with bipolar disorder cannot be excluded.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
IntroductionDisorders of endocrine function are among the most common etiology of psychiatric illness.The link between psychosis and hyperthyroidism is still poorly understood. We report an unusual presentation of hyperthyroidism as a psychotic state. Careful history, physical examination, and laboratory investigation, including thyroid function tests, should be part of the assessment of patients with any unexplained acute psychosis to detect this potentially curable disease. In this way, this article analyzes the psychiatric, physical and laboratory findings associated with hyperthyroidism and treatment.ObjectivesTo report a case of psychosis in a patient with endocrine disease.MethodsClinical records. Research on PubMed and Medscape using the Mesh Terms “hyperthyroidism”, “psychosis” and “thyroid and psychiatric manifestations”.ResultsWe present the case of a male patient, previously followed on our ambulatory psychiatric service for drug-induced psychosis. He was hospitalized due to psychotic symptoms, without substance abuse. Inpatient evaluation diagnosed hyperthyroidism. The patient did not present any somatic changes, except for psychosis. The patient was effectively treated with antipsychotics. He was referred to further evaluation and started antithyroid therapy.ConclusionsThyroid disease should be considered in the differential diagnosis of a broad spectrum of psychiatric symptoms. Psychosis is a rare complication of hyperthyroidism, ranging between 1–20%. The typical psychosis is reported to simulate manic-depressive psychosis. This association reinforces the need of a careful clinical evaluation in patients presenting with psychosis. Such psychiatric symptoms remit successfully with concomitant administration of antipsychotics and normalization of thyroid levels.Disclosure of interestThe authors have not supplied their declaration of competing interest.

Abstract
INTRODUCTION In schizophrenic disorders, supportive psychosocial therapies have been used as adjuncts to pharmacotherapy to help alleviate residual symptoms and to improve social functioning and quality of life. Among these therapies, psychoeducational therapies showed a significant efficacy on improving drug adherence and on reducing relapses. However, according to the French Health Agency, fewer than 10% of psychiatric structures in France offer registered psychoeducation programs. Caregiver apprehension of patients' depressive reactions to the awareness of the disease could underlie the underuse of psychoeducation therapies. Indeed, the psychoeducation programs' impact on objective and subjective quality of life is discussed among the literature. In this context, we conducted a retrospective, monocentric, open-labelled and non-controlled pilot study to measure the impact of a registered psychoeducation program on objective and subjective quality of life of patients suffering from schizophrenia. Secondary objectives included measures of the effects on drug observance and awareness of the disease. METHODS We included stabilized patients over the age of eighteen suffering from schizophrenia. Referent psychiatrics were asked to inform the patient of the diagnosis and to prescribe psychoeducation therapy. From 2011 to 2014, we offered three ambulatory programs, each program including fifteen two-hour group sessions. The groups were opened for three to six patients and managed by two caregivers. Themes discussed during the sessions included: schizophrenic disease, treatments, relationships to family, diet, social issues, toxics, relaxation. Objective and subjective quality of life were evaluated one month before and one month after the program using respectively the global assessment functioning (GAF) and the subjective quality of life (SQoL) scales. The Medical Adherence Rating Scale (MARS) and the French IQ8 scale evaluated respectively drug adherence and awareness of the disease. All patients gave their written consent for the study. Based on medical records and scales, we compared data before and after the program using the Wilcoxon test, adapted for small samples. RESULTS Fourteen patients, with a mean age of 37.6 years, were included. All patients had a chronic antipsychotic treatment and four benefitted from a bitherapy with a mood stabilizer. The mean length of disease was 15.3 years, with a mean number of 3.4 hospitalizations before inclusion. The participation rate was nearly twelve sessions out of fifteen. Mean GAF score before the program was 48/100. After the program, mean GAF score was significantly increased to 54/100 (P=0.008). As to SQoL score, we found a significant difference of the sub item psychological well-being from 3.2/5 before the program to 3.8/5 after the program (P=0.03). Global SQoL score and other sub items (self-esteem, resilience, and physical well-being) showed a slight but not significant improvement. The sub items family relationships and sentimental life were diminished, non-significantly. Concerning the drug adherence, the mean MARS score was significantly increased from 6.1 to 6.4/8 (P=0.03). Comparison of the insight IQ8 scale showed a slight but non-significant increase. When asked to note the program, patients were globally very satisfied, with a mean rate of 8.6/10. Of fourteen patients, one needed to be hospitalized three years after program. DISCUSSION This retrospective study on a small sample of patients suffering from schizophrenic disorder pointed out a significant improvement on drug adherence, objective quality of life and psychological well-being, after an eight-month registered program of psychoeducational therapy. These results are in line with a recent report from the Cochrane group who reported a significant raise of GAF associated with psychoeducational therapies. The literature data for subjective quality of life are more contradictory. Despite the small sample and evaluation means that need to be corrected in further studies, we reproduced the results described in the literature regarding the improvement on drug adherence. However, the stability of these effects should be checked in the medium and long term. CONCLUSION Adjunctive psychoeducation therapy has a positive impact on reducing relapses in schizophrenia. In this study, we showed a significant benefit on drug adherence, objective quality of life and psychological well-being on a small sample of patients and provide arguments for the development of psychoeducation programs which are currently underrepresented in France. Our results encourage conducting a further prospective multicenter controlled study on a larger sample to clarify the benefit of psychoeducational therapy on objective and subjective quality of life in schizophrenia.

Abstract
BACKGROUND Cutaneous melanoma is often characterized by its pigmented appearance; however, up to 8.1% of such lesions contain little or no pigmentation. Amelanotic melanomas, lesions devoid of visible pigment, present a diagnostic quandary because they can masquerade as many other skin pathologies. Recognizing amelanotic melanoma is even more clinically challenging when it is first detected as a metastasis to the secondary tissue. METHODS We report a rare case of metastasis of an amelanotic melanoma to the parotid gland. RESULTS A 75-year-old man presented with an 8-month history of a painless, mobile, hardened mass in the right parotid region. Histopathological analysis of a fine-needle aspiration biopsy of the parotid mass indicated that the mass was melanoma. Careful clinical and radiological examination revealed an 8 mm erythematous papule in the right temporal scalp, initially diagnosed by visual examination as basal cell carcinoma. After right superficial parotidectomy, neck dissection, and excision of the temporal scalp lesion, histological examination revealed the scalp lesion to be amelanotic melanoma. CONCLUSION Although metastatic amelanotic melanoma to the parotid gland is a rare diagnosis, the clinician should be familiar with this presentation to increase the likelihood of making the correct diagnosis and delivering prompt treatment.

Abstract
The hypothesis of cerebral plasticity in psychiatric disorders has encouraged clinicians to develop cognitive remediation therapy (CRT), a new therapeutic approach based on attention, memory, planning, and mental flexibility tasks. The first cognitive remediation programs were developed and validated for adults with schizophrenia and were shown to have a positive impact on executive functions as well as on quality of life. In children and adolescents, researchers emphasized the existence of executive dysfunction in neurodevelopmental disorders such as autistic spectrum disorder, attention deficit disorder, and eating disorders. For these disorders, neuropsychological studies suggest that memory, planning, attention and mental flexibility are impaired. Despite the paucity of studies on cognitive remediation (CR) in children, preliminary results have suggested, as in adults with schizophrenia, good compliance and optimization of executive functioning. Consequently, programs dedicated to young subjects were developed in English-speaking countries, and the Department of Child and Adolescent Psychiatry of Sainte Anne Hospital (Paris) developed a new CR program for children with attention deficit disorder, academic problems, or eating disorders. These programs complete the field of CRT proposed by Sainte Anne Hospital's Remediation and Psychosocial Rehabilitation Reference Center, initially designed for adults with schizophrenia. Our team used and adapted validated tools such as Delahunty and Wykes's CRT program (translated and validated in French by Amado and Franck) and Lindvall and Lask's CRT Resource Pack. One program was developed for an adolescent with anorexia nervosa and applied to the subject and her family, but the purpose of this paper is to present a CR approach for children with attention deficit disorder or academic disorder, a 6-month program based on paper-pencil tasks and board and card games. The team was trained in different kinds of cognitive remediation, and the program was applied by a clinical nurse with the supervision of a child and adolescent psychiatrist and the department's neuropsychologists. Paper-pencil tasks were adapted from the CRT program for adults; the card and board games used were geometric figures, illusions, Rush Hour(®), Set(®), Jungle Speed(®), Color Addict(®), etc. These games are available in stores and the program can be applied at home, which helps families set aside their preoccupations with their child's academic performance. Diagnostic and neuropsychological evaluations were done before the beginning of the therapy and repeated at the end of the 6-month program. This program does not ignore the metapsychological impact of the therapy, and work on self-esteem is also done. The presence of the therapist is necessary, which seems better than a computer program, which cannot encourage the young subject in the same personalized and empathetic way. We therefore conducted the first clinical feasibility trial of cognitive remediation in young subjects and present a clinical case of a 6-year-old boy with attention deficit disorder and academic disorder. The results of neuropsychological evaluations before and after therapy suggest improvement in executive functions and better self-esteem. Satisfaction for the boy and his family was high. Even if these results need to be replicated, cognitive remediation appears to be a new therapeutic tool, complementary to classical approaches used in childhood psychiatric disorders. The Department of Child and Adolescent Psychiatry will submit this program to a research program conducted by the National Health Department to study the impact of this approach in a controlled study.

Abstract
Les jeunes adultes consultant dans les services de psychiatrie générale présentent parfois des symptômes psychotiques associés à un développement atypique (troubles comportementaux dans l’enfance, troubles des apprentissages, etc.). Ces patients constituent un enjeu pour les équipes de psychiatrie adulte : la prise en charge apparaît souvent peu efficiente (intolérance aux traitements, difficulté à établir un projet de réinsertion, etc.). Pour ces cas complexes de « psychoses de l’adolescent », nous proposons dans notre unité de remédiation cognitive (C3RP) une investigation approfondie et multidisciplinaire de la période développementale, de la petite enfance jusqu’à l’émergence des premiers symptômes psychotiques. Cette relecture sémiologique nous permet d’affiner le diagnostic et de proposer un parcours de soin individualisé, combinant des traitements pharmacologiques et des prises en charge rééducatives. Nous présentons ici le cas de Mademoiselle C., jeune femme pour laquelle le diagnostic de schizophrénie a été porté initialement. L’examen neuropsychologique et l’entretien psychiatrique centré sur la petite enfance, associés aux examens biologiques, anatomiques et génétiques nous ont permis de repenser le diagnostic comme un trouble du développement avec symptômes psychotiques dans un contexte d’anomalie génétique de novo (microduplication 17p13.3). Un traitement pharmacologique adapté (aripiprazole, méthylphénidate et S-citalopram) ainsi qu’une rééducation logico-mathématique ont été associés à des programmes de remédiation cognitive (cognition froide et cognition sociale). Pour les aspects attentionnels, exécutifs et mnésiques le programme CRT avec une adaptation spécifique au cursus universitaire a été suivi. En parallèle, le SAMSAH Prepsy a pu ajuster au quotidien les conditions de son apprentissage et l’aider à la réalisation d’une formation d’assistante de librairie. Pour ces jeunes patients complexes avec nécessité cruciale d’un parcours de réhabilitation, la conjonction d’une remédiation et d’un service d’accompagnement au quotidien est décisive pour l’accomplissement des projets professionnels et personnels.

Abstract
INTRODUCTION Neurological soft signs (NSS) are subtle neurological abnormalities that cannot be linked to the achievement of a specific region of the central nervous system and which are not part of a particular neurological syndrome. These signs are observed in the case of diseases supporting the neurodevelopmental model such as schizophrenia in general and its early form defined notably by an age of onset of less than 18 years. Indeed, the NSS belong to a set of clinical, cognitive, electrophysiological and neuroanatomical markers reflecting neurodevelopmental brain abnormalities in patients with schizophrenia. OBJECTIVE The objectives of our study were to determine the prevalence, the scores, and the nature of neurological soft signs (NSS) in adolescent patients suffering from early onset schizophrenia diagnosis in comparison to healthy controls, and to explore the correlations between NSS and the demographic, clinical and therapeutic features of these patients. MATERIALS AND METHODS Twelve adolescents were recruited in the Child Psychiatry Department at the Razi Hospital (Tunisia), with the diagnosis of schizophrenia according to the DSM-IV supplemented by the Kiddie SAD PL. They were matched by age and educational level with twelve healthy controls without psychiatric family or personal history. The clinical status of the patients was assessed using the Positive and Negative Syndrome Scale (PANSS). Neurological soft signs (NSS) were rated with the Neurological Soft Signs Examination (NSSE) by Krebs et al. (2000) for the two groups. This scale is composed of 23 items exploring motor coordination, motor integrative function, sensory integration, involuntary movements and quality of lateralization. RESULTS The mean age of our population was 14.7 years. The average age of onset of the disease was 12.2 years. The sex-ratio was 1.4. Educational level was 7.4 years. The PANSS mean total score was 74.3. The mean daily dose, in chlorpromazine equivalents, was 523.9 mg/day. Four patients received a strict monotherapy of antipsychotics, while the other patients were receiving an association of two neuroleptics. The prevalence of NSS was 100% (cut-off point=11) with a mean total score of 29.3±4.1. The highest score was for the motor coordination (10.1). As for the control group, the mean total score was 7±1.3. A highly significant difference was found between patients and controls for all sub-scores of NSS. Negative correlations were found in patients, between age and neurological soft signs total score (P=0.05; r=-0.57) and also with sensory integration score (P=0.04; r=-0.58). The NSS total score was also correlated with low educational level (P=0.03; r=-0.61). There was no correlation between neurological soft signs scores and PANSS scores or the daily dose of antipsychotics. CONCLUSION The prevalence and NSS scores are high among young people with early onset schizophrenia diagnosis illustrating the existence of structural abnormalities of the brain, themselves consequences of early neurodevelopmental disturbances, which would support the neurodevelopmental hypothesis concerning this pathology.

Abstract
INTRODUCTION Teenagers and adults with intellectual disabilities are nowadays "over-handicapped", often due to lack of care in self-sufficiency and continued learning, two essential domains for living in a community. Their cognitive limits, particularly on the executive functions, could be an obstacle to their involvement in the daily life activities, through their difficulties to plan, anticipate, shift and maintain information in working memory. These high level mental functions can be taught with the CRT program (Cognitive Remediation Therapy - Wykes and Reader 2005) developed in other pathologies and providing an adaptation regarding the developmental level of the person. METHODS Firstly, it is essential to determine cognitive developmental levels of the teenager or the adult, using standard tools, such as Wechsler scales. Secondly, functional and/or adaptative levels have to be assessed using specific tools, such as the Vineland Adaptative Behavior Scale 2nd Edition (VABS-II, Sparrow et al., 2005) and the Functional Intervention Scale (EFI, Willaye et al., 2005). Finally, in order to clearly distinguish what are the preserved and impaired cognitive domains, standard tools assessing executive functions such as the Wisconsin Card Sorting Test, the Tower of London, Stroop Test and BADS are used if possible for the patient. The setting of cognitive remediation programs, previously developed for schizophrenic patients, requires adaptation for teenagers and adults with intellectual disabilities, taking into account the limitation of their cognitive abilities. In this paper, we will show that the CRT method for cognitive remediation is particularly relevant for subjects with intellectual disabilities. This method is hence focused on strategies and exercises to improve working memory, categorization and moreover executive functions. Of course this method might need adaptations, with examples based on simplification of the different tasks, notably for verbal materials, and with variations of the media used. These sessions will be part of a wider individualized caring project, allowing the person to transfer the cognitive acquisitions to his/her daily life. CONCLUSION The use of cognitive programs adapted to people with intellectual disabilities can provide benefits in the development of autonomy and daily life activities, leading to a better quality of life and self-esteem.

Abstract
L’intérêt de la remédiation cognitive (RC) s’appuie sur l’observation de défaillances des fonctions exécutives dans de nombreux troubles psychiatriques. L’hypothèse est celle d’une restructuration cognitive du fait de la plasticité cérébrale et de la possibilité de remaniements cellulaires neurologiques stimulo-dépendants. Chez les enfants et les adolescents, des essais ont été réalisés chez des sujets cérébro-lésés et chez des sujets présentant un trouble déficit de l’attention/hyperactivité, un trouble du spectre autistique, un trouble des apprentissages ou une anorexie mentale [2–5]. Les programmes de remédiation cognitive s’appuient sur des tâches informatisées ou papier–crayon ou sur des jeux de société ciblant les déficits des fonctions exécutives. Le Centre Hospitalier Sainte-Anne a développé, depuis 2010, un centre psychiatrique de référence de remédiation cognitive et de réhabilitation psychosociale (C3RP) qui propose à des sujets adultes des programmes de Cognitive Remediation Therapy (CRT) [1]. En outre, depuis 2011, notre équipe réalise un travail clinique préliminaire de faisabilité en proposant à des enfants, en complément d’approches classiques appliquées en routine (rééducatives et/ou psychothérapiques), une prise en charge en RC. Nous utilisons des tâches « papier–crayon » de la CRT adaptées à l’enfant ainsi que des jeux de société issus des programmes anglo-saxons qui permettent à l’enfant d’utiliser différentes ressources cognitives. Notre but est d’améliorer les performances cognitives de ces enfants dans les domaines suivants : la flexibilité mentale, l’attention, la mémoire et la planification ainsi que l’estime de soi. Une évaluation neuropsychologique incluant un WISC-IV ; une figure de Rey et des sub-tests de la NEPSY mettent en avant des résultats prometteurs, illustrés par une vignette clinique portant sur un enfant qui a fait de nets progrès dans quatre dimensions sur cinq ciblées (Fig. 1). Ces résultats doivent être étendus à d’autres patients et sur d’autres centres pour envisager la généralisation de cette approche.Fig. 1

Abstract
During visuo-spatial cognitive tasks, patients with schizophrenia show a preference for local (detailed) rather than global (holistic) information processing. The efficiency of such information processing is influenced by task difficulty. We tested whether patients' preference for local processing would persist if task demands favored global or local processing. Twenty-four stabilized patients with schizophrenia (SZ) and 25 healthy, matched controls (C) were tested in a mental mirroring task. Task difficulty was manipulated while stimulus surface structures were maintained unchanged. Information processing was assessed by recording eye movements. SZ were slower than C in the easiest condition but they made more errors than C in the more difficult conditions. Further, SZ did not adapt their average fixation duration to task demands resulting in longer fixation duration in the easiest condition and shorter fixation duration in the most difficult condition compared to C. These findings suggest that patients employ local information processing even when it is maladaptive for task demands. That is, patients do not adapt their fixation duration to task demands implicating (i) a preference for scanning local stimuli features and (ii) information processing inflexibility. These features need to be taken into account when evaluating visuo-spatial cognitive performance in schizophrenia.

Abstract
BACKGROUND Many studies have focused on specific motor signs in autism and Asperger's syndrome, but few has been published on the complete range of neurological soft signs (NSS) in children with pervasive developmental disorder (PDD). Scarce are the studies evaluating NSS in children suffering from PDD not otherwise specified (PDDNOS). METHODS This study compared performance of 11 autistic children (AD) and 10 children with PDDNOS, with controls matched on age, sex and cognitive performance on Krebs et al.'s NSS scale. Because of the duration of the assessments and specific difficulties encountered in managing some items, an adaptation of the scale had to be made during a pilot study with the agreement of the author. To be eligible, patients had to meet the following inclusion criteria: an age range of 6-16 years, a diagnosis of autistic disorder or PDDNOS based on the DSM IV criteria (American Psychiatric Association 1994). The autism diagnostic interview-revised (ADI-R) was used in order to confirm the diagnosis and to evaluate the association of the symptoms to the severity of the NSS. The childhood autism rating scale (CARS) was completed for the patients in order to evaluate symptoms at the time of the NSS examination. Cognitive ability was assessed with Raven's progressive matrices. Were excluded patients with: history of cerebral palsy, congenital anomaly of the central nervous system, epilepsy, known genetic syndrome, tuberous sclerosis, neurofibromatosis, antecedent of severe head trauma, Asperger's syndrome, obvious physical deformities or sensory deficits that would interfere with neurological assessment, deep mental retardation and recent or chronic substance use or abuse. Healthy controls shared the same exclusion criteria, with no personal history of neurological, psychiatric disorder or substance abuse, no family history of psychiatric disorder and normal or retardation in schooling. All study procedures were approved by the local Ethics Committee (Comité d'éthique, Razi Hospital), according to the declaration of Helsinki. RESULTS There was no difference between patients and controls with respect to sex, age and cognitive function. All children had an IQ higher than 81. Significant differences were found between AD children and control group in the motor integration function and sensory integration function. Different NSS scores were significantly higher in the PDDNOS group than in controls: the total scores, motor coordination, motor integration function, sensory integration and abnormal movements. Lower performance in motor coordination skills was associated with higher ADI-R communication score in the AD group. No relationship was found between NSS and CARS' total sore. CONCLUSION This study confirms the impaired neurological functioning in autistic as well as PDDNOS children. The association of motor impairment with autistic symptoms highlights the argument that motor control problems can be part of the autism spectrum disorders. The lack of relationship between NSS and intellectual aptitude in the clinical sample provides new elements for the neurodevelopment model of the autism spectrum.

Abstract
BACKGROUND Ocular-motor inhibition errors and saccadic hypometria occur at elevated rates in biological relatives of schizophrenic patients. The memory-guided saccade (MS) paradigm requires a subject to inhibit reflexive saccades (RSs) and to programme a delayed saccade towards a remembered target. METHOD MS, RS, and central fixation (CF) tasks were administered to 16 patients who met the criteria for DSM-IV schizophrenia, 19 of their psychiatrically healthy siblings, and 18 controls. RESULTS Patients and siblings showed elevated MS error rates reflecting a failure to inhibit RSs to a visible target, as required by the task. In contrast to controls, prior errors did not improve MS accuracy in patients and siblings. CONCLUSIONS The specific characteristics of the elevated MS error rate help to clarify the nature of the disinhibition impairment found in schizophrenics and their healthy siblings. Failure to inhibit premature saccades and to improve the accuracy of subsequent volitional saccades implicates a deficit in spatial working-memory integration, mental representation and/or motor learning processes in schizophrenia.

Abstract
INTRODUCTION Most visual environments contain more information than the human brain can process in real time. To overcome this limitation, the attention system acts as a filter by selectively orienting attention to specific regions of the visual field. This ability to orient attention can be reflected in covert shift processes of attention. LITERATURE FINDINGS In a typical covert orienting task, subjects have to maintain fixation on a central cross and respond as quickly as possible to a target, which appears in a peripheral box following a cue that summons attention to the direction where the target is going to appear (valid cueing) or to the contralateral direction (invalid cueing). When the cues are nonpredictive, the response characteristics critically depend on stimulus-onset asynchrony (SOA). With short SOAs (<300ms), valid cues result in a reaction time advantage over invalid trials, which is due to a reflexive shift of attention towards the source of stimulation. In contrast, with longer SOAs, valid cues result in longer reaction times to the subsequent target. DISCUSSION This phenomenon is known as the inhibition of return and is mostly thought to reflect an inhibitory mechanism protecting the organism from redirecting attention to previously scanned insignificant locations. Many studies have reported blunted or delayed inhibition of return in patients with schizophrenia. However, some authors reported normal amounts of inhibition of return. This can be partly explained by the use of manipulations of the covert orienting of the attention paradigm that is known to enhance the course of inhibition of return. CONCLUSION The deficit of inhibition of return seems to be time-stable and to be unrelated to psychopathology or length of illness. The contribution of neuroleptic medication to this deficit cannot be determined. Recent data suggest a deficit of inhibition of return in two human models of psychosis (dimethyltryptamine and ketamine). Further studies should clarify whether blunted inhibition of return might represent a trait marker of schizophrenia.

Abstract
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.

Abstract
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.

Abstract
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.

Abstract
Using infrared oculography, we compared saccades toward predictable and pseudo-random visual targets in 19 neuroleptic-free patients with schizophrenia (including 13 neuroleptic-naïve patients) and in 29 age- and gender-matched healthy volunteers. Externally driven saccades were not different between patients and controls, whether or not the target was predictable. Anticipated saccades were specifically less accurate in the patients compared to the controls. The difference between primary gain of anticipated and non-anticipated saccades was markedly higher in the patients compared to controls (p=0.003). These results point to a deficit in the early step of internally driven oculomotor planning in schizophrenia.

Abstract
Eye movement anomalies are more frequent in schizophrenic patients than in healthy subjects. This study deals with visually guided saccadic eye movements in seventeen schizophrenic patients [ten untreated (neuroleptic-naive or free), seven treated patients] and their correlations between symptoms presented by patients and oculomotor performances. There was no significant difference between the patients and the control group in visually guided saccades tasks. However, negative correlations between oculomotor performance and positive or disorganisation symptomatology were found. Thus, although no major oculomotor dysfunction in response to external stimulus was seen in schizophrenic patients, some symptoms were linked to oculomotor performance impairment. Thus psychiatric symptoms might share some common cerebral circuits which those involved in oculomotor tasks.

Abstract
RATIONALE Many biological abnormalities have been found in obsessive-compulsive disorder (OCD). The circadian rhythm investigations of different clinical and biological parameters may provide a comparison with depression. Fluoxetine is one of the efficient drugs in alleviating symptoms of OCD. The effect of fluoxetine can highlight some clues to the neurotransmitter alterations in the disorder. OBJECTIVE The present study investigated clinical and biological circadian modifications in OCD patients during a fluoxetine treatment. METHODS Daily clinical symptoms, and circadian rhythms of axillary temperature, plasma cortisol and plasma melatonin were assessed in eight patients suffering from OCD. These parameters were compared in the same patients, before and after an 8-week fluoxetine treatment period. RESULTS A therapeutic effect of fluoxetine was obtained. No significant differences were observed either in daily clinical variations or in biological circadian rhythms measured before and after treatment. CONCLUSION The therapeutic efficacy of fluoxetine was not related to the biological parameters assessed.

Abstract
Recent studies of memory in schizophrenia have shown that explicit but not implicit memory performance is impaired. The hypothesis that schizophrenia is associated with a failure of consciously but not unconsciously (automatic) controlled influence of memory on performance was tested using a procedure providing uncontaminated estimates of consciously controlled and automatic memory processes (i.e., the process-dissociation procedure in a stem completion task). Performance of 35 patients with schizophrenia was compared with that of 35 normal participants. Consciously controlled use but not automatic influences of memory was significantly lower in patients with schizophrenia than in controls. Consciously controlled use of memory was negatively and significantly correlated with positive symptoms of schizophrenia. Schizophrenia differentially affects 2 types of memory processes: It impairs consciously controlled use of memory but spares automatic influences. Positive symptoms could reflect the lack of control from higher level conscious processes.

Abstract
Behavioral modifications induced by psychotropic drugs result primarily from their pharmacological properties. According to classification of psychotropic drugs, sedative compounds contrast with psychostimulating medications. Behavioural effects of psychotropic drugs depend on dosing, subject's status (patient or healthy volunteer), acute or chronic administration, and environment. Some psychotropic compounds, particularly sedative drugs, decrease the level of mental alertness and cognitive functioning. But those deleterious effects tend to disappear during the course of a repeated administration. Some psychotropic drugs, especially benzodiazepines, induce a tolerance effect, eventually a psychic or a physiological dependence state evidenced by withdrawal reactions. Such similar dependence processes have been reported with other psychotropic drugs. Forensic problems have been attributed to some psychotropic compounds, like benzodiazepines: paradoxical aggressive reactions, psychomotor automatism. Psychotropic drugs usually can confer a positive effect on behaviour owing to their therapeutic action by the way of improving the illness and consequently the life of patients in the cases of depression, anxiety or schizophrenia.

Abstract
The prevalence rate of transsexualism varies from 1 to 50,000, to 1 to 100,000. Although it remains an infrequent affliction, transsexualism generates usually major suffering and may be responsible of many complications like suicide, self-mutilations, affective disorders and social disabilities. Since the first descriptions of Esquirol in the nineteenth, the medical community has always been questioned on medical, legal, social or ethical aspects of transsexualism. The aetiology of the trouble is still unknown. In the absence of biological marker, the syndrome of transsexualism can be defined only with clinical criteria. The main differential diagnosis are sexual ambiguities and psychotic disorders. For the specialists, satisfying the patients demand of a surgical and social reassignment still remains the only way to improve their clinical condition and avoid the onset of many dramatic complications. Without any treatment, the evolution of the trouble is chronic, without remission. Longitudinal studies of transsexual patients with a five year follow-up demonstrated subjective improvement in two thirds of the patients and don't find either higher rates of suicides nor psychotic decompensations after surgery and hormonotherapy. Clinical and neuropsychological studies of sexually differentiated cognitive abilities of transsexual patients, before and after hormonotherapy, could allow us in improving the understanding of sexual differences of the brain.
