Introduction Sleep disturbances are commonly observed in schizophrenia and are associated with worse psychotic symptoms and poorer clinical outcomes. This has generated considerable interest in characterizing the relationship between disturbed sleep and schizophrenia. Objectives The aim of this study is to assess sleep quality in patients recently diagnosed with schizophrenia that are antipsychotic-naïve and to analyze their association with sociodemographic and clinical data in the same patient group. Methods We conducted a cross-sectional, descriptive and analytical study among patients in the psychiatry department "G" at Razi Hospital, over a period of six months. Three scales were used: the Global Assessment of Functioning (GAF) Scale, the Positive and Negative Syndrome Scale (PANSS) and the Pittsburgh Sleep Quality Index (PSQI). Results The mean age of patients was 26.8 years and 65% were male. The mean age of onset of the disease in patients included in our study was 24.8 years. The majority of patients (96.3%, n=52) were considered poor sleepers (PSQI threshold value >5). We objectified a negative and statistically significant association between patient functioning (total GAF score) and sleep quality (r= -0.277, p=0.043). The PSQI total score was positively and significantly correlated with the negative scale scores (r=0.315, p=0.021), the general psychopathology scale scores (r=0.411, p=0.002) and the PANSS total score (r=0.378, p=0.005); while no significant association was objectified with scores of the positive scale. Conclusions Our study has demonstrated a high prevalence of sleep disorders during the first episode of schizophrenia, as well as their association with the severity of symptoms.

Introduction Substance abuse is a common problem associated with significant morbidity and mortality, but is often underdiagnosed and unrecognized in geriatric patient populations. Objectives to determine the prevalence of substance use disorders geriatricic inpatient population. Methods Data from 2010 to 2020 were retrospectively reviewed from a clinical database. 148 admissions of patients older than 60 years were identified. Descriptive statistics were used to group patients with and without a diagnosis of substance use, which included intoxication, withdrawal, abuse, dependence, and substance-induced disorders. Results There were 148 hospital admissions for patients over 60 years of age, with a mean age of 72.38 ± 5.64 years and a mean length of stay of 13.91 ± 14.15 days. Of all admissions, 44% (n=64) were associated with at least one substance use diagnosis. In this group of 64 patients, the most frequently used substance was tobacco with associated disorders ( 65% N=42). The prevalence of other substance use diagnoses was as follows: sedative-hypnotic abuse/dependence 32% (N=21), cannabis abuse 10% (N=6), alcohol-related disorder 12.5% (N=8). Compared with patients without a substance abuse diagnosis, these patients were significantly younger, had shorter lengths of stay, were less likely to be readmitted, and were more likely to be single men Conclusions Given the inherent difficulties in diagnosing substance use disorders and the retrospective nature of this study, the true prevalence of substance use disorders in elderly psychiatric inpatients is likely higher than found. Cross-sectional or cohort studies are more appropriate to shed light on this condition. Disclosure of Interest None Declared

Introduction Data on the differences between young and elderly patients with bipolar disorder and between elderly patients with early and late age of onset are limited. Objectives to study the clinical differencies between bipolar patients with an onset in old age and other bipolar patients. Methods This is a retrospective study of 420 bipolar patients. In this study, patients with onset after age 60 (n=37) were compared to other patients with early-onset bipolar (EOB) (<>50 years; n=383). Results In the year before recruitment, older patients more frequently reported a rapid course of the illness, but fewer suicide attempts , more often a single psychotropic medication and had less severe manic and psychotic symptoms, atypical antipsychotics were administered less frequently. but no difference in depressive symptomatology was observed. Conclusions Elderly bipolar patients differ from younger bipolar patients in course and treatment. Medication use and the occurrence of rapid cycling in elderly bipolar patients deserve careful investigation. Disclosure of Interest None Declared

Introduction Despite the projected growth of the geriatric population, there is currently no clear treatment framework for these patients. This treatment requires specific training for psychiatrists in the field of geriatric psychiatry. Objectives to evaluate the attitudes of psychiatric residents in Tunisia with regard to gerontopsychiatry. Methods All psychiatry residents at Razi Hospital in Tunis in April 2022 were asked to complete an anonymous online survey with questions related to previous experience with the elderly, exposure to geriatric psychiatry patients during medical school, future career plans and interest in pursuing a geriatric psychiatry rotation, and factors involved in their decision. Results 55 of 72 (76%) residents responded, of whom 63 (n=34)% were in their second year of residency. 69% (n=38) of residents reported no exposure to geriatric psychiatry patients during medical school, but of those who had, 70% (n=24) had a positive experience. Only four residents (7%) reported considering a career in geriatric psychiatry. With respect to the geriatric psychiatry curriculum, all residents felt that changes were needed in geriatric psychiatry education and career path. Conclusions Residents’ interest in further training in geriatric psychiatry is low. The most common reason is the perception of a poor prognosis for this patient population. Future studies are needed to develop strategies to increase interest in this field. Disclosure of Interest None Declared

Introduction During the course of COVID-19 pandemic, the respiratory system is the most commonly affected while many neuropsychiatric manifestations of the disease have been observed. Objectives Emphasize the importance of detecting psychiatric symptoms in patients infected with Covid 19. Methods Presentation of case report Results A 44-year-old woman with no personal history of chronic diseases and with no psychiatric family history. About her experience with covid 19, her mother died as a result of covid 19 infection and our patient had been hospitalized for 17 days for pulmonary infection covid 19, during her hospitalization in COVID 19 unit she presented insomnia and anxiety without behavioural disorders. She had a good evolution of the respiratory symptoms and she was discharged under corticotherapy and anticoagulants. She was admitted in our department after 45 days of her covid 19 infection for acute behavioural disorders. On physical examination: she was hemodynamically stable and well oriented. Neurological examination was with no abnormalities. Cerebral CT scan was normal and lumbar puncture was indicated and the analysis of the CSF did not reveal any anomalies. At the psychiatric interview she was extremely agitated, anxious and hallucinated, she had disorganised speech with derailment and neologisms, she was disinhibited and her mood was exalted. She presented also a delusion of grandeur and delusion of persecution. Conclusions In individuals presenting with COVID-19 infection, consideration should be made for psychiatric manifestations because COVID-19 diagnosis predispose vulnerable patients to psychosis.

Introduction The diagnosis of leukemia in a child is a difficult moment for the therapist and for the parents. Nevertheless, this moment is crucial and determining in the course of care and the therapeutic relationship. Objectives Determine the quality of diagnosis announcement among mothers of children with leukemia. Methods A cross-sectional study was conducted at Aziza Othmana hospital department of haematology in Tunisia between June and July 2021. We have questioned the mothers about the announcement of the diagnosis: the space frame, the time provided and the availability of the doctor. Results We included 31 mothers, their middle age was 41 years old. Acute lymphoblastic leukemia is the most frequent type of cancer in our sample (94%). According to 4 mothers (13.3%), the diagnosis of leukemia was not announced before the start of treatment. The quality of the diagnostic announcement was judged to be good in 40% of cases (n=12), average in 12.7% (n=8) and mediocre in 20% of mothers (n=6). The space frame of the announcement was perceived as appropriate with respecting confidentiality in 18 mothers (69.2%). The time provided for the announcement was considered sufficient for 17 mothers (65.4%). The doctor who announced the diagnosis was described as available by 69.2% of the mothers and unavailable by 30.8% of the mothers. Conclusions The quality of the diagnosis announcement amoung mothers of children with leukemia in our context is not optimal. Oncologists must be trained in diagnostic announcement and must be aware of the importance of this moment in the subsequent therapeutic relationship. Disclosure of Interest None Declared

Introduction The evolution of schizophrenia with age remains poorly studied. The prevalence of negative symptoms in elderly people with schizophrenia is even less described in the literature. Objectives to evaluate the prevalence of remission of negative symptoms in the elderly and to study the sociodemographic and clinical variables associated with this remission. Methods The sample consisted of 83 subjects aged 55 years and over, followed at the psychiatry department "G" of the Razi hospital in Tunis and suffering from schizophrenia according to the DSM5 criteria. Global remission was defined as a score below 4 on the seven negative symptom items of the PANSS. A questionnaire was administered to each patient to collect epidemiological and anamnestic data. Results 59% of the sample showed remission of global negative symptoms. 84% and 60% were in remission on the emotional and cognitive subscales, respectively. The existence of remission was correlated with lower PANSS global score, more preserved cognitive functioning, later age of onset, more family and social support, and the absence of a concomitant somatic illness. Conclusions This study showed that measures to optimize treatment of positive symptoms and cognitive functioning may have an impact on negative symptoms. Similarly, quality of social network in later life impacts the level of negative symptoms. Disclosure of Interest None Declared

Introduction Announcing a diagnosis of leukemia is a difficult process, especially for a vulnerable population of children. Objectives Determine the attitude of caregivers in the announcement of diagnosis of leukemia among children. Methods A cross-sectional study was conducted at Aziza Othmana hospital department of haematology in Tunisia between June and July 2021. We have questioned the mothers about the announcement of the diagnosis of leukemia to their children. Results We included 31 children with leukemia, 71% of these children were male. Their average age was 10 years ±4.5 with extremes from 4 to 17 years of age. The majority of the children (80.6%) were of school age. The three children who were six years old were not able to integrate into a school and fifteen children stopped their studies because of their disease. Acute lymphoblastic leukemia was the most frequent type of cancer (94%). Fifty five per cent (55%) of these children were not informed of their disease according to their mothers. Conclusions The provision of adapted information, through individualized assessments of each child’s needs, can contribute to the improvement of the child’s experience of the disease.

Introduction Patients with chronic schizophrenia experience significant disturbances in the quality and quantity of their sleep and it had been mainly attributed to severity of symptoms and antipsychotic use. Recent studies suggested that antipsychotic-naïve early course patients with schizophrenia and their non-psychotic first-degree relatives also show altered sleep quality. Objectives In this study we aimed to compare sleep parameters in antipsychotic-naive first-episode schizophrenia patients to their healthy siblings and age- and sex-matched healthy controls. Methods We conducted a cross-sectional, descriptive case-control study in the Psychiatry « G » department at Razi Hospital, for a period of six months. Our sample consisted of three groups: a group of schizophrenic patients, a group of their healthy siblings and a group of healthy controls. The three groups were matched by age and sex. The Positive and Negative Syndrome Scale (PANSS) was used to assess the severity of symptoms in patients with schizophrenia. The Morningness-Eveningness Questionnaire (MEQr), Epworth Sleepiness Scale (ESS), and Pittsburgh Sleep Quality Index (PSQI) were used in the three groups to assess Circadian preference, daytime sleepiness and sleep quality. Results There was no significant difference between the groups regarding the chronotype. Patients had significantly higher daytime sleepiness compared to siblings (p=0.001) and controls (p

Introduction Psychiatric admissions of elderly subjects with mental disorders is a difficulty in management and treatment. This problem is essentially related to somatic comorbidities of this population. Objectives To compare the demographic characteristics, comorbid conditions and functional status of younger and older individuals with major mental illnesses admitted to psychiatry. Methods Using the records of patients admitted between 2015 and 2020 to the psychiatric department "G" of Razi Hospital, we collected the demographic characteristics, comorbid conditions and functional impairments for patients admitted to psychiatry and aged over 65 years. We compared these characteristics to those collected in the total population of admitted patients. Results The study population consisted of 75 elderly patients. Compared to the youngest patients there was a greater male majority, a higher rate of severe cognitive impairment, higher rates of chronic medical illnesses, such as congestive heart failure. Conclusions Our findings suggest an urgent need for integrated psychiatric and medical care for elderly subjects with major mental illness. Future research is needed to adapt evidence-based integrated models of collaborative mental health care. Disclosure of Interest None Declared

Introduction Charles Bonnet Syndrome (CBS) is an age-related disorder characterized by complex visual hallucinations in older persons with vision loss and underlying ocular pathology. The management of these symptoms is imprecise and combines psychological measures with psychotropic drugs. Objectives to discuss the non-pharmacological management of Bonnet syndrome through a case report. Methods We report a case of atypical CBS in a 76-year-old male patient presenting with visual and auditory hallucinations that were improved by reassurance. Results The past medical history was significant for diabetic retinopathy, difficulty hearing due to bilateral sensorineural hearing loss. He recognized these visions as unreal and felt distressed by them. No cognitive impairment was observed on several neuropsychological tests. He was reassured of the false nature of the visual experiences after explanations that he had no mental illness and that the problem could disappear. He was taught how to keep the images away by closing his eyes for sometimes and repeated blinking. After six weeks of psychological intervention, the visual experiences had disappeared without using any drug Conclusions In the management of CBS drug treatments remain partially satisfactory. Nonpharmacological interventions focus on the reduction of the visual pathway deprivation. This therapeutic alternative seems to provide positive benefits. Disclosure of Interest None Declared

Introduction Nowadays, the smartphone use is increasing, similar is the trend among medical students and professionals. The problematic use of mobile phone has become a major public health concern as it may lead to its addiction and other disorders such as sleep disorders, depression and decreased life satisfaction. Objectives This study aims to determine the association between mobile phone usage, Insomnia and depressive symptoms among medical students and medical professionals. Methods We conducted a descriptive and analytical study among 40 medical students and doctors. They were asked to fill out an anonymous online survey. Problematic Use of Mobile Phones (PUMP) scale was used to assess mobile phone usage. Insomnia Severity Index (ISI) was used to screen for insomnia and the Patient Health Questionnaire-9 (PHQ-9) to screen for depression. Results The mean age of participants was 27,8 years, with a sex ratio of 1/3. The mean of the duration of mobile phone use was 3.4 hours per day. We found that 77% of participants spend most of their time on social media (Facebook, Instagram, Tik Tok) when using their mobile phones. In our study, participants with higher problematic use of mobile phone (PUMP) score were significantly more likely to present symptoms of insomnia (p=0.031) and depression (p=0.023) according to ISI and PHQ-9 scales. Furthermore, a significant association was found between the duration of mobile phone use, Insomnia and depression. In fact, the Odds Ratio (OR) of Insomnia was 1.66 in participants who used mobile phone more than 2 hours per day compared to those who used mobile phone < 2 hours per day. Similarly, the OR of depressive symptoms was significantly increased with prolonged mobile phone use (>= 2 hours per day) compared to those who used it

Introduction Bipolar disorder is a frequent and particularly severe psychiatric pathology that causes significant morbidity and mortality. The rapid cycling forms are more severe in terms of their expression, evolutionary course, therapeutic responses and associated comorbidities. Objectives The aim of this study is to conduct a descriptive assessment of therapeutic characteristics in patients with rapid cycling bipolar disorder. Methods Our work involved a population of 97 patients followed for bipolar disorder diagnosed according to DSM5 criteria, including 37 patients meeting the specification “with rapid cycles”. The patients were divided into two groups: - Group of patients with bipolar disorder with rapid cycles (TBCR) - Group of patients with bipolar disorder without rapid cycling (TBNCR). We compared the therapeutic features among these two groups. Results The dominant polarity was depressive in patients with rapid cycles. They required more mood stabilizers. A greater proportion of them had received treatment with serotonin reuptake inhibitor antidepressants. They were more likely to use hypnotics such as antihistamines and zolpidem. Conclusions Rapid cycling TB is a relatively common clinical modality that should be investigated and identified.The use of antidepressants is associated with this course of the disease. Their utilization in the treatment of bipolar depression must be thoughtful and well studied Disclosure No significant relationships.

Introduction The epidemic of COVID-19 has affected the psychological health of people, especially frontline medical and paramedical staff. Several coping strategies have been used to combat the impact of this virus on their lives. Objectives Describe the impact of coronavirus on mental health and identify coping strategies Methods We carried out a cross-sectional, descriptive and analytical study, conducted over a period of two months ( september and october 2020), in 22 hospitals in Tunisia, including frontline medical and paramedical staff. To evaluate anxiety and depression, we used the Beck Inventory. To identify coping strategies, we used the Brief COPE. Results We collected 78 professionals. The mean age was 29.86+-5.4. The majority were medical residents (67.9%) working in covid units in 39.7% of cases. The rythm of work was daily in almost half of the cases, giving direct care to the patients tested positive in 76.9%. More than half had not received adequate training, and protective equipment was available in only 50% of cases. We found 35.9% of the staff who had to move for fear of infecting their families. More than half of the frontline staff were victims of stigma (57.7%). Depression and anxiety were tested minor in 40%. The most used coping strategy in the face of this distressing virus was social support (64.1%) followed by emotion-focused mechanisms (53,8%). Social support strategy was significantly correlated with prevention of anxiety (p=0.048) Conclusions Participants practiced and recommended various coping strategies to deal with stress, depression and anxiety emerging from COVID-19 pandemic.

Introduction Tinnitus is an auditory perception of a “phantom” nature with highly changing features. There is an established correlation between anxiety, depression, sleep disorders and tinnitus. Objectives To evaluate the prevalence of sleep disorders and emotional disorders during tinnitus and their correlation to the severity of the symptomatology Methods A descriptive cross-sectional study of 60 patients consulting for subjective tinnitus. For each patient we collected epidemiological data and performed an ENT and general examination, an audiometric and psychoacoustic evaluation and a psychometric evaluation. To evaluate the severity of the tinnitus we used the visual analog scale VAS and the subjective tinnitus severity test (STSS). Disability was assessed by the Tinnitus Handicap Inventory (THI). Anxiety and depression were assessed by: the Hamilton anxiety Rating scale and the Beck depression inventory. Results The prevalence of emotional disorders was: 21.7% for depression, 48.33% for generalized anxiety disorder, 11.67% for dysthymia, 5% for agoraphobia 16.67% for panic disorder and 1.67% for social phobia. The intensity of tinnitus was correlated with more panic disorder (p=0.008). Subjective severity of tinnitus was correlated with disability (p=0.0001), awareness of tinnitus in relation to sleep duration (p=0.006) and disturbed sleep (p=0.047). Disability was correlated with subjective tinnitus severity (p=0.0001), panic disorder (p=0.0007), generalized anxiety disorder (p=0.033), and poor sleep quality (p=0.005). Conclusions Our results emphasize the importance of emotional disorders as well as sleep disorders in chronic “tinnitus”. These disorders should be systematically investigated and eventually treated in order to optimize the management of the patients. Disclosure No significant relationships.

Introduction Marfan syndrome is an autosomal dominant systemic disorder with connective tissue defects in multiple organ systems. Cardinal manifestations of this syndrome involve the cardiovascular, the skeletal and the ocular system. Interestingly, many cases of patients with Marfan syndrome and schizophrenia have been reported. Objectives Discuss the etiological link between Marfan syndrome and schizophrenia Methods Presentation of a clinical case illustrating the comorbidity between schizophrenia and marfan syndrome. A search was conducted in PubMed database using the terms : schizophrenia AND Marfan syndrome. Results Ms JW a 36-year- old single women, she had schizophrenia since the age of 20 years, she was hospitalized in our service for psychotic relapse in a context of treatment discontinuation. She had a personal history of persistence of the ductus arteriosus for which she had been operated during her childhood, a scoliosis operated and multiple pathological fractures. On mental status examination, she was distressed and hallucinated, She had disorganized thought processes and a paranoid delirium. On physical examination, she had features suggestive of Marfan syndrome such as crowded teeth, a high arched palate, arachnodactyly , hyperlaxity and a high myopia. We don’t dispose genetic evaluation for marfan syndrom because of the nonavaibility of facilities to perform genetic analysis. Several studies have indicated that psychiatric symptoms might be part of the clinical profiles of marfan syndrom. However, their relationship and underlying pathogenesis are not easily clarified. Conclusions Co-occurrence of marfan syndrom and schizophrenia might be explained by some shared etiological pathways between both disorders. Disclosure No significant relationships.

Introduction The current coronavirus pandemic is a unique and unusual situation. It is putting the general population under severe strain.

Introduction Mental disorders of pregnancy or postpartum correspond to all the psychopathological states linked to the period of the pregnancy-puerperium. They are the subject of prevention and screening and are currently a public health priority Objectives Describe the socio-demographic characteristics of the patients who presented mental disorders during pregnancy and/or postpartum. Identify the various risk factors predisposing to these disorders Methods We carried out a retrospective descriptive analytical study including patients who presented mental disorders during their pregnancy or postpartum and who were hospitalized during the period from January to October 2020.We collected 20 patients. Results The average age was 39.84 years. Mental disorders were present in 73.7% during the postpartum period. The patients had a personality disorder in 47.7%. They were smokers in 57% of cases. Pregnancy was desired in 73.7% with regular follow-up in 84.2%. Pregnancy was complicated by toxemia in 22% of cases and gestational diabetes in 27% of cases. Delivery was by caesarean section in 68.4% with primiparity in 50%. According to the DSM5, the psychic disorder most often found during pregnancy was the characterized depressive disorder 43%, and during the postpartum we found the brief psychotic episode 42.1%. The treatment was in half of the cases association between antidepressants and antipsychotics. Mental disorders were significantly correlated with the presence of stressful life events during pregnancy (p =0.02) Conclusions Mental disorders during pregnancy and postpartum are frequent and important to detect. Early diagnosis and adequate care are the two essential elements that should allow these women to fully experience their motherhood

Introduction Bipolar disorder is a frequent and serious psychiatric disease. Antipsychotics are habitually required for its management especially during an acute manic episode. The association of cancer with bipolar disorder may impact psychiatric management. The choice of the adequate antipsychotic drug remains a challenge in this case. The clinical benefit of tamoxifen is obtained after the hepatic metabolism with cytochrome P450 2D6 which generates endoxifen, the potent metabolite of tamoxifen. Evidence has emerged that antipsychotics may potentially inhibit the CYP2D6. Study data supporting this interaction are rare. Objectives In this work, we aimed to illustrate the modalities of care of bipolar disorder in a patient receiving tamoxifen. Methods Presentation of a clinical case of a patient treated by Tamoxifen for her breast cancer and who was admitted in our department for acute mania with psychotics features, followed by a literature review. Results A 53-year-old woman with past history of breast cancer diagnosed in 2018, treated with lumpectomy and radiation, followed by tamoxifen. She has been admitted in 2019 in our department for an acute mania with psychotics features. Olanzapine was prescribed with good clinical evolution. The psychiatric and oncologic status of the patient was stable after one year under tamoxifen and olanzapine. Conclusions Psychiatrists must be aware that some of the prescribed medications co-administered with tamoxifen interfere with the CYP2D6 function, which may potentially increase the risk of breast cancer recurrence. A close collaboration between psychiatrists and oncologists is required to adapt therapeutic protocols.

Introduction Tamoxifen is an antioestrogen agent used in breast cancer treatment. According to some guidelines, this molecular was also proposed for the treatment of acute mania. In fact, Tamoxifen inhibits the intracellular action of the protein kinase C (PKC), which is the direct target in the treatment of mania episodes. Lithium and valproate have also the same action. Objectives We aimed to show the case of an acute mania under an inhibitor PKC treatment and insisted that other studies are recommended. Methods Case report description and research on medline, pubmed with the keywords: Tamoxifen, Bipolar disorder, protein kinase C,mania. Results We reported a case of a 53-year-old woman with past history of unipolar depression. In 2018 when she was diagnosed with breast cancer. She received antidepressant drugs but she interrupted the treatment after a few months. She was treated for her breast cancer with mastectomy, radiotherapy, and 20 mg per day of Tamoxifen prescribed since Mars 2018. She had been admitted in June 2019 in our department for acute mania. The patient received Tamoxifen as it was prescribed. She was not taking any concomitant medications. No history of drug abuse was reported. Medical examination, laboratory, and radiological investigations did not indicate any medical pathology. Conclusions In our case, Tamoxifen had not ovoid the acute mania in spite of its Known anti-manic properties as reported in the literature. Possible neurobiological effect of tamoxifen on the nervous system should be studied to evaluate the safety of this treatment mainly in patients with bipolar disorder.
