Introduction Tunisian emigrants may consume psychoactive substances in other countries. This community is exposed to sociocultural and legal contexts different from those in Tunisia and the degree of acculturation would tend to increase over time. However, data on the use of psychoactive substances, particularly cannabis, in this particular population are scarce. Objectives This study aims to determine the profile of Tunisian young adults residing abroad who use cannabis. Methods We conducted a cross-sectional, descriptive and analytic study. It was carried out in the form of an online survey. We focused on young Tunisians people who have completed their secondary studies at the pilot high school of Sfax and currently residing abroad. Data collection was through Google Forms administred questionnaire. Results Thirty-five participants were included in our study. Cannabis use behavior affected 48.6% of them (N=17)) and it was done with friends in a festive setting in 88% of cases (N=15). Cannabis use was more common among people who were single (p=0.001), living alone (p=0.047), had a psychiatric history (p=0.032) and hanging out with friends who also smoked cannabis (p=0.032).Cannabis use was also more common among cigarette smokers (p=0.000) and alcohol consumers (p=0.000). It was significantly more common among people who shared erroneous beliefs about cannabis, that it is a mild drug (p= 0.024) and that it does not cause dependence (p= p=0.042). Conclusions Cannabis use among Tunisian young adults residing abroad seems to be a form of poly-consumption, more common among singles, living alone and having a psychiatric vulnerability. These findings underscore the need for targeted interventions and educational initiatives to address cannabis use within this specific population. Disclosure of Interest None Declared

Introduction Understanding adolescents perceptions of their weight status and the factors influencing these perceptions is pivotal for developing targeted interventions and policies to counteract the rising obesity trends. Objectives This cross-sectional study aimed to determine the accuracy of weight status perceptions among Tunisian adolescents compared to objective metrics and to identify sociodemographic characteristics and life habits associated with the underestimation of weight status. Methods A cross-sectional, school-based study was conducted among a randomized sample of adolescents attending secondary schools in Sousse, Tunisia. A total of 1399 students participated, with anthropometric measurements taken, and a pre-tested Arabic questionnaire administered to gather sociodemographic data and perceived weight status, assessed using the Figure Rating Scale (FRS). The accuracy of perceived weight status was determined by comparing the measured weight status with participants; self-reported perceptions. We evaluated the association between body weight distortion and life habits which included regular physical activity, screen time (time spent on internet per day), number of fruits and vegetables consumed per day, and fast-food consumption. Results The study achieved an 86.68% response rate, with over half of the participants being female (60.5%), and the average age being 17 years. The majority of adolescents (41%) perceived themselves as having normal body weight, while 34.5% perceived themselves as underweight, 16.6% as overweight, and 7.9% as obese. However, based on BMI categories, 72.6% had a normal measured weight, 20.4% were overweight, and 6.9% were obese. A substantial proportion of participants (45.6%) underestimated their weight status, with a significant proportion being objectively overweight or obese (26%). Furthermore, we found a significant association between the perception of weight accuracy with four correlates: gender, mother educational level, regular physical activity, and the number of fruits and vegetables consumed per day. Conclusions The findings revealed a disparity between perceived and actual weight status among Tunisian adolescents, with a significant underestimation of weight status, particularly among those who are overweight or obese. The results highlighted the crucial need for interventions that address weight perception inaccuracies and promote healthy weight awareness and management among adolescents in Tunisia. The study underscored the importance of further research to understand the development and progression of body weight underestimation throughout adolescence and the roles of lifestyle behaviors in shaping weight perceptions.

Introduction Psychological vulnerability and problematic psychotropic drug use among medical residents are critical and intricate areas of study in the field of healthcare and mental well-being. This topic looks into the potential links between the psychological vulnerabilities experienced by medical residents, which are frequently associated with the demanding nature of their profession, and their use of psychotropic drugs in a way that poses problems or risks. Exploring this relationship is critical for understanding the mental health challenges that medical residents face and developing effective strategies to support their psychological well-being. Objectives to identify the psychological factors linked to problematic psychotropic drug use in medical residents. Methods We conducted a cross-sectional descriptive and analytical study among Tunisian medical residents between August and September 2022. We used a self-administered questionnaire with a data collection form, the DAST-10 (Drug Abuse Screening Test) scale, and the DASS-21 (Depression, Anxiety, and Stress Scale) in an online survey. Data was analyzed using the 20th version of the SPSS software. Results The sample consisted of 80 medical residents. Among them, 23.8% (n=19) had reported a previous use of psychotropic drugs, and 15% (n=12) a misuse (without a prescription and/or without following the prescription). The DAST-10 revealed that 6 residents (31.6%) had problematic use of psychotropic drugs. A high level of stress on the DASS-21 scale was associated with a problematic use (p=0.01) and a misuse (p=0.01) of psychotropic drugs. Furthermore, residents with high stress levels were more likely to demonstrate problematic use of psychotropic drugs (p=0.004). Such problematic use was correlated with personal history of anxiety disorders (p=0.01). Furthermore, residents with problematic psychotropic drug use had higher anxiety and depression scores on the DASS-21 scale (p>0.05). Conclusions Our findings revealed a concerning prevalence of psychotropic drug use among medical residents and an association with high stress levels. This result emphasizes the need for targeted interventions to support young doctors’ mental health. Disclosure of Interest None Declared

Introduction Chromatin modifications and epigenetics are important pathogenesis mechanisms leading to various neurologic and psychiatric disorders including epilepsy, drug addictions, depression, autistic spectrum, learning disabilities and schizophrenia. Recently, the disruption of the chromatin remodeling BAF complex has been linked to several neurodevelopmental syndromes, commonly referred to as PBAFopathies. Objectives Here, we review the implication of PBAF complex genes in schizophrenia and we outline syndromes caused by mutations in these chromatin-modifying enzymes labelled as PBAFopathies to discuss the functional consequences of reported mutations in the literature. Methods We comprehensively review the scientific literature using Pubmed database and other search platforms such as Google scholar to state the role of PBAF complex genes in schizophrenia and to reveal the most frequent genes mutations reported in literature. Results Our review revealed that the human analogs of the subfamily of ATP-dependent chromatin remodeling complexes, which are known in eukaryotes as the mammalian SWI/SNF complex (counting a group of proteins that associate and possess a DNA-stimulated ATPase activity that can destabilize histone-DNA interactions in reconstituted nucleosomes providing crucial nucleosome rearrangement and allowing the activation/repression of genes) are crucial for the regulation of genes expression and cells differentiation. They involve two well-known complexes which are SWI/SNF-A (known as BAF complex) and SWI/SNF-B (known as Polybromo-associated BAF or PBAF complex). SWI/SNF is a multisubunit chromatin-remodeling complex that performs fundamental roles in gene regulation, cell lineage specification, and organismal development and mutations that inactivate SWI/SNF subunits are found in nearly 20% of human cancers and in various developmental disorders, forming a continuum or spectrum of diseases. Since the first description of BRG1/BRM mutations in schizophrenia, other mutations of the SWI/SNF subunits have been reported: SMARCA1, SMARCA2, SMARCA4/BRG1, etc. Single nucleotide polymorphisms (SNPs) in these and other genes of PBAF have been also associated with schizophrenia. Conclusions This review focuses on the PBAF SWI/SNF subunits to find out if schizophrenia may be considered as a member of the spectrum of PBAFopathies. Disclosure of Interest None Declared

Introduction Turner syndrome characterized by total/partial and/or homogeneous/mosaic X chromosome monosomy is associated with various physical health concerns, including facial dysmorphism, short stature, infertility, and other organ defects such as heart, kidney, bone, skin, … as well as variable degrees of cognitive impairments. Besides, social skills, communication and relationships are usually disordered. Objectives The aim of this study was to report social challenges of Turner syndrome particularly related to discrimination regarding physical and cognitive impairments. Methods A retrospective analysis of clinic data and karyotypes were carried out for the patients diagnosed with Turner syndrome among patients who consulted at our genetic counselling at the medical University of Sfax, during the last two decades. Cytogenetic analysis were carried out using conventional methods and RHG banding with analysis of at least 20 metaphases and 3 karyotypes for each patient. Social challenges were recorded for each patient during pre-cytogenetic consultation and oriented questioning. Results We identified 23 cases referred with a cytogenetic diagnosis of monsomy X. The karyotyping was indicated for dysmorphism, primary or secondary amenorrhea, female infertility and recurrent pregnancy losses. Homogeneous X chromosome monosomy was recorded in 13% of cases, whereas mosaic forms with and without structural X/Y abnormalities were more frequent (82%). The mean age of patients in the study was twenty years. When the 45,X population was the predominant one (56,5%), dysmorphism and primary amenorrhea were constant. In the mosaic forms, clinical traits of Turner syndrome were insignificant. Discrimination based on physical appearance, intellectual disability, and failure to conceive were the three types of social challenges revealed by patients of our study. Parents of Turner patients were also concerned at the psychological level. They in fact revealed their emotional distress face to stressful experiences of their children with Turner syndrome regarding the social discrimination they encountered particularly in schools. Conclusions Social challenges related to discrimination based on physical appearance, intellectual disability, and failure to conceive in Turner syndrome lead to depression, low self-esteem and anxiety.

Introduction The prevalence of alterations of liver function tests in patients with schizophrenia and bipolar disorders is not well known. These alterations are often considered as side effects of medication Objectives Our study aimed to evaluate and compare liver function before and after treatment in patients with schizophrenia (SCZ), schizo-affective disorder (SCA) and bipolar disorder (BD). Methods This was a prospective study among patients with SCZ, SCA and BD according to DSM-5 criteria. Patients, from the “C” psychiatry department of Hedi Chaker University Hospital in Sfax, were assessed during both acute and remission phases in their illness. The acute phase (T0) assessment was made in drug-free patients from june 2016 to july 2018. As for the remission phase (T1), it was made between november 2019 and march 2020. Blood tests were performed in the Laboratory of Biochemistry at Habib Bourguiba University Hospital in Sfax. Clinical and biological parameters of patients were compared with those of healthy controls. Biological assessment consisted mainly in Aspartate Aminotransferase (AST), Alanine Aminotransferase (ALT) and Albumine. Results Thirty patients were included in our study. Their mean age was 35.83 ± 12.24 years and they were all males. They suffered from SCZ in 33.33% of cases, from SCA in 26.66% of cases and from BD in 40% of cases. Psychoactive substance use was common among 80% of patients. In the remission phase, 90% were polymedicated with use of antipsychotics in 83% of cases and mood stabilisers in 53% of cases. Table 1 shows the evolution of the studied liver function markers in our patients.Table 1: evolution of some liver function markers in patients Markers T0 T1 p AST (UI/L) Patients 33,22 ± 23,18 19,34 ± 4,97 0,05 a: significant difference between patients with SCZ (T1) and controls; b: significant difference between patients with BD (T1) and controls; e: significant difference between patients (T1) and controls Conclusions Our results showed an improvement of liver function in patients with SCZ and BD after treatment. This suggests that liver function alterations are due to these diseases rather than the medication. Disclosure of Interest None Declared

Introduction Maintaining sexuality is important to the well-being of women, particularly after menopause and benefits of sexual satisfaction in terms of emotional well-being and quality of life have been well demonstrated. Objectives This study aims to assess the sexual health behaviors in Tunisian women during and after menopause and the awareness of Tunisian partners about the role of the quality of their sexuality regarding their physical and psychological wellbeing. Methods We comprehensively review the scientific literature using Pubmed database to state Tunisian literature regarding sexual behaviors and function in women during and after menopause. Interviews with twenty Tunisian women after menopause about sexual health have been conducted. Results Our bibliographic research revealed a poor literature with only two papers responding to our inquiry but among a specific female population investigated after experiencing breast cancer “Female sexuality in premenopausal patients with breast cancer on endocrine therapy and sexuality after breast cancer: cultural specificities of Tunisian population”. Interrogated women reported a poor sexual satisfaction as well as sexual difficulties in the partner or with him. In fact, there is an important wrong understanding of the female anatomy and physiology by both partners, for the female sexual satisfaction. There is also many wrong cultural ideas about menopause and sexuality. Conclusions Currently, sexuality in Tunisian women during and after menopause is influenced by ageing, by previous sexual function and experiences, the male domination in partner’s sexual practices and the sexual functioning in the partner. In general, there is an unfavorable body image and disturbed sexual health. Disclosure No significant relationships.

Introduction The low prevalence of some genetic neuro-developmental syndromes associated to psychiatric disorders requests to be integrated in human genome-phenome databases from which pleiotropy can be compiled from by systematic integration of phenotypes associated with genetic loci using phenomic inference tools. Williams-Beuren syndrome (WBS) is a neurodevelopmental disorder related to elastin gene at 7q11.23. Anxiety, depression and attention problems are the main behavioral problems found in WBS with no gender differences. Significant differences between cohorts are reported in particular regarding somatic complaints and aggressive behavior. Objectives Here, we report a Tunisian cohort of WBS patients for whom clinical behavioral phenotypes as well as genetic features are detailed. Methods Sixteen patients from Sfax, Tunisia were referred for genetic assessment due to a suspected WBS syndrome. Results Genetic evaluation using fluorescent in situ hybridization confirmed 7q11.23 microdeletion in only eight patients. Comparison of detailed behavioral phenotypes revealed differences between age groups, gender groups and genetic groups. Anxiety and depression were recorded in the two older male patients and aggressive behavior was recorded in only two boys. The severity of behavioral features were dependent to familial environment and to parental socio-economic and educational levels. Conclusions A more complete understanding of phenomic space is critical for elucidating genome-phenome relationships mediating neurodevelopmental disorder associated to psychiatric diseases for assessing and managing psychiatric and behavioral risks in young syndromic children.

Introduction Age at onset of pediatric bipolar spectrum disorder (BSD) is an important marker of a more severe form and a highly heritable mood/mental disorder. Objectives Here, we report a familial Tunisian BSD follow-up study showing a very early onset of the BSD at the neonatal period. Methods A 28-year-old female and her 30-year old sister were referred for genetic and psychological assessments due to recurrent depressive episodes. Results Psychological assessment revealed a BSD type II with episodes of hypomania for both patients. The 30-year old sister presented a mixed form of BSD coupled with autistic traits, hyposomnia and obsessive-compulsive behaviors. Intellectual and cognitive abilities were without concerns. Familial history revealed BDS among paternal relatives including the brothers’ and sisters’ father as well as all their uncles offspring’s, and their grandparents, who were consanguineous. The depressive mood was a common sign in the three generations. Personal history revealed significant signs of a very early onset of the disorder since the neonatal period for the two sisters as well as for their four paternal cousins who also presented BSD features. Familial risk of BSD in this family correlates with a variably higher personal risk of other psychiatric disorders such as anxiety, drug abuse, personality disorders, and autism spectrum disorder. Conclusions Environmental conditions, familial care and educational level have a strong correlation with the severity and the efficiency of cognitive management of BSD and its psychiatric comorbidities. BSD is highly heterogeneous and polygenic and personalized management has considerable clinical repercussions benefits. Disclosure No significant relationships.

Introduction Rarely, thyroid cancer can lead to hyperthyroidism. The link between dysthyroidism and psychiatric symptoms is well established, but cases of psychosis associated with hyperthyroidism are rarely reported in the literature. Objectives Identifying psychosis secondary to hyperthyroidism caused by a secreting tumor through a case and literature review. Methods We report the case of a patient with thyroid suspect tumor and chronic psychosis. We performed a literature review based on a PubMed search with the following keywords: “dysthyroidism psychosis”. Results Mr. S,32, with a personal psychiatric history of chronic psychosis evolving since 4 years, without notable pathological history, was hospitalized in psychiatry for psychomotor instability, verbal hetero-aggressiveness, subtotal insomnia and refusal of treatment. The psychiatric examination revealed the presence of a chronic delusional syndrome with a theme of persecution, mysticism,and an interpretive, intuitive and hallucinatory mechanism, without dissociative syndrome. The somatic examination objectified a cachectic patient with a bilateral symmetrical non-impulsive exophthalmos, a goiter with a thrill on palpation, dysphonia and sinus tachycardia.A laboratory workup revealed inflammatory syndrome, collapsed TSH (

Introduction The COVID-19 pandemic represents a stressful event for humanity. The spread of this disease mainly affects health professionals and interests them closely. Objectives Identify the impact of the COVID-19 pandemic on the mental health of healthcare personnels and associated factors exposing them to increased psychological fragility. Methods The current article is a narrative review of the existing literature. A search on electronic database like PubMed was undertaken using the search terms “coronavirus mental health healthcare workers”. 20 articles were included in this review. Results Studies revealed that health care workers have prensented considerable psychiatric symptoms such as anxiety, depression, PTSD, stress, insomnia, somatization, mental and physical exhaustion, addiction and obssessive compulsive symptoms. The prevalence of these symptoms varies from study to another with almost a more notable prevalence of anxiety and depressive symptoms. The following factors that predispose to developing mental distress were noted: being a frontline health worker, having direct contact with infected patients, working in a city with a high infection rate, female sex, isolation, being a suspected case, stigmatization, change of organization, lack of materials, lack of information, lack of communication, lack of support, fear of contamination or of contaminating loved ones, having an organic pathology. Conclusions This notable impact of the pandemic on the mental health of healthcare workers alerts us as colleagues and civil society to the ultimate need for an urgent adequate and up-to-date intervention to alleviate this distress.

Introduction Women around the world are still victims of violence and discrimination in many areas. In Tunisia, discrimination against women remains a reality, and they are often more vulnerable to violence, especially sexual violence, compared to men. Objectives To describe the epidemiological characteristics of victims of sexual assault in the Mahdia region in Tunisia Methods This is a descriptive and retrospective study of 110 sexual assault cases examined at the legal medecin department of Mahdia University Hospital between January 2016 and August 2018. Results The majority of victims were female (80 %). All genders, 77% were under the age of 25 years old. The median age of the men was 11.5 years. The median age of women was 18. The urban origin was more common (55.5%). Only 8.1% were married compared to 87.4% single. Only 2.7% said they were divorced and only one woman was a widow. 41.8% of the sample said they were still in school and almost 29,1% of the cases were out of work. 3.6% reported a history of sexual assault. The sexual act was the same in all situations. The perpetrator was unique in 73.6% of cases, male (100%), known to his victim (57%) or even a member of the family circle (14%). Sexual assault by penetration was mostly reported (51%), and it was almost exclusively penile(98.2%). Conclusions Sexual violence remains under-reported. The statistical data do not allow to know the phenomenon of its whole, because the majority of acts remain unknown, due to the absence of complaints or medical consultations.

Introduction Several studies have mentioned the link between psychotrauma and psychosis. A direct causal link remains to be discussed. Objectives Evaluate the link between sexual abuse and psychosis. Methods We report the case of a male patient who developed schizophrenia following sodomy rape. We performed a literature review based on a PubMed search with the following keywords: “rape sodomy psychosis”. Results Mr. M., 26 years old, with a personal psychiatric history of chronic psychosis evolving for 10 years, consulted us for follow-up of his schizophrenia. When he was 16, the patient was raped by sodomy by a 40-year-old man under stabbing threat. After this incident, the patient did not verbalize this trauma, he isolated himself, became irritable and aggressive and has had olfactory hallucinations. The symptomatology worsened until the age of 24 when the patient presented a delusional syndrome with a theme of persecution, mysticism, bewitchment by a mechanism of interpretation and visual hallucinations. Then,he was hospitalized in psychiatry for psychomotor instability, verbal hetero-aggression. He had been diagnosed with schizophrenia evolving over 9 years. Treatment with an antipsychotic: risperidone and valproic acid was started. The evolution was quickly favorable but the patient currently presents blunted affect, a sexual disinterest and a strong desire for revenge from his rapist. Treatment adjustment and psychotherapy would be considered. Conclusions The onset of subsequent rape psychosis and the persistence of symptoms related to the trauma are arguments in favor of a direct causal link between sexual abuse and schizophrenia. Disclosure No significant relationships.

Introduction Clozapine is the drug of choice for patients with an unsatisfactory response to classic antipsychotic treatment. Little is known about the involvement of clozapine in the development of parotid disease. Objectives Identify the clinical characteristics of Clozapine-induced parotitis through a case and literature review. Methods We report the case of a patient with a refractory schizoaffective disorder, bipolar type and who developed recurrent parotitis while taking clozapine. We conducted a literature review based on a PubMed search of articles published on this subject with the following keywords: ‘parotitis clozapine’. Results Miss W., 34 years old, suffers from a severe schizoaffective disorder that has been diagnosed for several years. She has received various psychotropic medications. She suffered from frequent relapses that required recurrent hospital admissions. One year ago, a diagnosis of treatment-resistant schizoaffective disorder was made. The decision to introduce clozapine, associated with mood stabilizer treatment, was made on the basis of her treatment refractory symptoms. She experienced considerable sialorrhea after beginning clozapine treatment. Miss W. developed bilateral recurrent swelling over both temporal-mandibular areas after 6 months of treatment. It often appears after eating and lasts from 4 to 6 hours. There was no change in white blood cell count and she was afebrile. An otolaryngologist was consulted and a diagnosis of clozapine-induced parotitis was suggested. A spasmolytic and an anticholinergic treatment were prescribed and clozapine was continued. Conclusions This iatrogenic effect of clozapine must be recognized by clinicians in order to be better prevented.

Introduction Lorazepam is a benzodiazepine derivative that is globally used for the therapy of anxiety and insomnia. Objectives The objective of our work was to show that Lorazepam can be a cause of unexpected liver injury even though it is a rare entity. Methods We reported the case of a patient who had a Drug-Induced Liver Injury (DILI) under Lorazepam. We performed a literature review based on a PubMed search with the following keywords: “Lorazepam,DILI”. Results A 20 year-old-Tunisian woman was hospitalized in the psychiatry department of the hospital of Nabeul in Tunisia for a brief psychotic episode.She had a DILI under Olanzapine, Chlorpromazine and Lorazepam, which conducted us to interrupt her treatments except for the Lorazepam(5mg/day). The hepatic tests went back to normal even under Lorazepam. Few days later, the liver enzymes increased again to reach very high levels. Extensive workup was negative for other causes of liver injury, including viral hepatitis A, B, C and E.; capillary electrophoresis of serum proteins was normal; Exhaustive immunological tests were performed searching for auto immune hepatitis(anti-smooth muscle antibodies, anti-LKM1, anti-LC1, anti-SLA/LP) primary biliary cholangitis(anti-mitochondrial antibodies, anti-GP210, anti-sp100) and other antibodies like antinuclear antibodies were negative. Liver biopsy showed polymorphic inflammatory infiltrate including some eosinophilic polynuclear cells and rare vaguely epitheloid macrophages, with necrotico-inflammatory foci in the lobules, all of which were consistent with DILI. Lorazepam was discontinued and within 10 days her liver enzymes decreased and completely normalized. Conclusions Lorazepam, with an unknown action mechanism, can be a cause of DILI.

The seismic hazard map of the larger Europe-Africa-Middle East region has been generated as part of the global GSHAP hazard map. The hazard, expressing Peak Ground Acceleration (PGA) expected at 10% probability of exceedance in 50 years, is obtained by combining the results of 16 independent regional and national projects; among these is the hazard assessment for Libya and for the wide sub-Saharan Western African region, specifically produced for this regional compilation and here discussed to some length. Features of enhanced seismic hazard are observed along the African rift zone and in the Alpine-Himalayan belt, where there is a general eastward increase in hazard with peak levels in Greece, Turkey, Caucasus and Iran.

Local earthquake data collected by seven national and regional seismic networks have been compiled into a travel time catalog of 32341 earthquakes for the period 1980 to 1995 in South-Central Europe. As a prerequisite, a complete and corrected station list (master station list) has been prepared according to updated information provided by every network. By simultaneous inversion of some 600 well-locatable events we obtained one-dimensional (1D) velocity propagation models for each network. Consequently, these velocity models with appropriate station corrections have been used to obtain high-quality hypocenter locations for events inside and among the station networks. For better control, merging of phase data from several networks was performed as an iterative process where at each iteration two data sets of neighbouring networks or groups of networks were merged. Particular care was taken to detect and correctly identify phase data from events common to data sets from two different networks. In case of reports of the same phase data from more than one network, the phase data from the network owning and servicing the station were used according to the master station list. The merging yielded a data set of 278007 P and 191074 S-wave travel time observations from 32341 events in the greater Alpine region. Restrictive selection (number of P-wave observations >7; gap
