[Post-traumatic stress disorder, depression and anxiety in parents of children with epilepsy]. / Trouble stress post traumatique, dépression et anxiété chez les parents d'enfant(s) atteint(s) d'épilepsie.

INTRODUCTION: Post-traumatic Stress Disorder (PTSD), depression and anxiety are the most common psychiatric consequences among parents of children with epilepsy. OBJECTIVES: We aimed to investigate the prevalence and predictors of PTSD, depression and anxiety in a sample of parents of children with epilepsy. METHODS: A survey of 135 parents of children with epilepsy, treated in the pediatric neurology department at the Sfax Teaching Hospital in Tunisia, was conducted in the last quarter of 2019. The PTSD Checklist for DSM-5 and the Hospital Anxiety and Depression Scale (HADS) were used to assess, respectively, PTSD, depression and anxiety in parents. Associations with clinical and demographic variables with PTSD, depression and anxiety were evaluated in a logistic regression model. RESULTS: Results revealed PTSD rates of 20.7%, depression rates of 28.9% and anxiety rates of 55.6%. The main factors associated with PTSD on multivariable analysis were female gender (P=0.026, ORa=13.1), insufficient involvement of partner in disease management (P<10-3, ORa=12.1) and duration of epilepsy less than 12 months (P=0.001; ORa=0.1). Female gender (P=0.006, ORa=18.1) and restriction of social life (P=0.006, ORa=4.1) were associated with depression. Factors associated with anxiety were insufficient involvement of partner in disease management (P=0.03, ORa=4.6) and PTSD (P=0.005, ORa=9.1). CONCLUSION: These findings suggest that clinicians should pay more attention to psychological health of parents of children with epilepsy and help healthcare providers to develop preventive and intervention strategies for parents of such children.

[Metacognitive deficit in schizophrenia: Characteristics and links]. / Déficit métacognitif dans la schizophrénie : caractéristiques et liens.

OBJECTIVES: Research indicates that many patients with schizophrenia experience deficits in metacognitive capacity defined as the ability to form complex representations of themselves and others. The aim of the current study was to assess metacognitive deficit in patients with schizophrenia. These variables were collected together with many other sociodemographic, clinical and therapeutic data. METHODS: We conducted a descriptive and analytical cross-sectional study in the psychiatry department at the Hedi Chaker University Hospital in Sfax (Tunisia). Patients were in a non-acute phase, defined by the absence of any psychiatric symptoms during the last four weeks, also, no changes in medication during the previous month had been required. An informed written consent was obtained, following which patients completed questionnaires assessing sociodemographic and clinical data during structured interviews. Symptoms and severity of the illness were assessed using the Positive and Negative Symptoms Scale (PANSS). Insight was assessed using the Insight Scale (Q8). In addition, the Metacognition Assessment Scale-Abbreviated (MAS-A) was used to assess metacognitive capacities. The MAS-A contains four dimensions: self-reflectivity, awareness of the mind of others, decentration, and mastery. Higher scores reflect an ability to effectively respond to psychological challenges on the basis of psychological knowledge. RESULTS: We recruited 74 adults with schizophrenia disorder. The diagnosis was with DSM5. Their average age was 45 years (SD=9.84 years) with a sex ratio (M/F) of 1.552. Nineteen patients (25.5%) were married, and low educational level was present in 43% of cases. Forty patients (54%) were unemployed. Metacognitive deficit was detected in all the patients. They had low levels in all four dimensions of metacognition. The most affected dimension in our series was "Mastery". All patients had an overall insight score less than six (the average score was 2.73) with poor awareness in 62% of patients. The main factors correlated with metacognitive deficit were: occupational inactivity (P-0.015), Primary education level (P=0.045), tobacco consumption (P=0.002), low insight (P-0.001), negative symptomatology (P<10-3) and the use of first generation of antipsychotics (P=0.003). The multivariate analysis showed that three factors (occupational inactivity, low insight and the presence of negative symptomatology) were predictors of metacognitive deficits. CONCLUSION: Based on our results, occupational inactivity, negative symptomatology and low insight are predictors of metacognitive deficit in schizophrenia. Specific therapeutics should be proposed to act on these factors. A metacognitive training program, tailored to this vulnerable population, is a priority to improve their quality of life.

[Effects of continuous positive airway pressure on depression, anxiety and quality of life in obstructive sleep apnea hypopnea syndrome patients]. / Effets de la ventilation en pression positive continue sur la dépression, l'anxiété et la qualité de vie au cours du syndrome des apnées-hypopnées obstructives du sommeil.

INTRODUCTION: The obstructive sleep apnea hypopnea syndrome (OSAHS) is a chronic stressor that may alter the emotional state and quality of life (QOL) of patients suffering from it. In this work, we proposed to estimate the prevalence of depression and anxiety, to assess the QOL in a Tunisian population of apneic patients, and to assess their evolution under continuous positive airway pressure (CPAP). METHODS: We conducted a prospective study, involving 33 apneic patients followed for SAHOS with moderate or severe class disease in the pneumology department at Hedi Chaker university hospital in Sfax, Tunisia. They received CPAP treatment for three months. We used an epidemiological record. Two scales, the Hospital Anxiety and Depression Scale (HADS) and the 36-item Short-Form Health Survey (SF-36), were completed before and after treatment to evaluate the effect of three months of treatment with CPAP. RESULTS: The prevalence of depression in the study's patients, according to the HADS, was 45.5% and that of anxiety was 21.2%. After 3months of CPAP, the prevalence of depression and anxiety had become 18.2% and 6.1%, respectively. QOL was impaired in 81.8% of cases before treatment, according to the SF-36. This figure had decreased to 69.7% after 3months of treatment with CPAP. Apart from the third dimension (physical pain), all other dimensions were significantly improved after 3months of CPAP treatment. The treatment with CPAP induced a significant improvement in the average scores of depression (P<0.001), anxiety (P=0.002) and QOL (P<0.001). CONCLUSIONS: These results attest to the importance of the frequency of anxio-depressive disorders as well as an altered QOL in patients with OSAHS. CPAP treatment was shown to be effective in improving these parameters, but this efficacy was partial. Specialized care may be needed in cases of residual anxio-depressive symptoms.

[Variations in immunological parameters after treatment of a manic episode]. / Variations immunologiques après traitement d'un épisode maniaque.

Bipolar disorder is a chronic and disabling mental illness affecting approximately 1-2% of the general population, characterized by the occurrence of manic episodes alone or alternating with depressive episodes. Bipolar disorder is associated with significant morbidity, mortality and personal suffering. The mechanisms underlying the onset and progression of bipolar disease are still poorly understood. Recently, immunological dysfunctions have been suggested in the pathogenesis of bipolar disorder, and many studies have focused on the interaction between bipolar disorder and immunity. Immunological changes have been widely studied during depressive episodes but less explored during manic episodes. The objective of our study was to explore changes in serum proteins and autoantibodies after treatment for a manic episode of bipolar I disorder. This study was carried out over a 30-month period from January 2017 to June 2019, in collaboration between the psychiatry department B of the Hédi Chaker CHU and the immunology department of the Habib Bourguiba CHU, in Sfax, Tunisia. It focused on a sample of 45 bipolar patients with manic relapse, naïve to psychotropic treatment, or discontinuing treatment for a period of at least three months and without a history of autoimmune disease. The study was conducted in two stages : on admission and after treatment. The mean plasma levels of IgG and complement C3 fraction were significantly higher in bipolar patients with relapsing mania. Studies of variation in immunoglobulins and complement fractions during relapses of bipolar disorder have all objected to variations in these serum proteins, but their results were inconsistent regarding the direction of variation and the fractions affected. After treatment, there was a statistically significant increase in the mean plasma levels of IgG and IgA and a decrease in the mean plasma level of the C4 fraction of complement. No significant variation in autoantibodies was noted after treatment. The mean plasma IgM level was significantly lower with sodium valproate. On atypical antipsychotic medication, the mean plasma level of fraction C3 was statistically lower, whereas on conventional antipsychotic medication it was statistically higher. This is in line with the data in the literature which support the immunomodulatory role of thymoregulators and antipsychotics. Serum proteins have been more sensitive than autoantibodies to the effect of psychotropic therapy during manic relapse.

[The handling of psychotropics in diseases of central nervous system]. / Le maniement des psychotropes dans les maladies du système nerveux central.

Psychiatric signs and symptoms occur frequently in individuals with central nervous system diseases. Inadequately treated, these comorbid conditions affect patient rehabilitation, compliance with treatment and quality of life. Their management poses a major challenge given the variable efficacy and safety profiles of available psychotropic drugs and increased risk of drug interaction. This review aims to summarize the existing literature on the prescription of psychotropic drugs for management of psychiatric disorders among persons with central nervous system's diseases.

[Factors associated with Internet addiction among Tunisian adolescents]. / Facteurs associés à la cyberaddiction chez les adolescents Tunisiens.

INTRODUCTION: Internet addiction, a relatively new phenomenon, is a field of recent research in mental health, particularly within young populations. It seems to interact with several individual and environmental factors. OBJECTIVES: We aim to spot internet addiction in a Tunisian adolescent population, and to study its relationship with personal and family factors, as well as with anxious and depressive comorbidities. METHODS: We conducted a cross-sectional study of 253 adolescents recruited in public places in the city of Sfax in the south of Tunisia. We collected biographical and personal data as well as data describing family dynamics. The internet addiction was assessed by Young's questionnaire. Depressive and anxious co-morbidities were assessed using the HADS scale. The comparative study was based on the chi-square test and the Student's test, with a significance level of 5 %. RESULTS: The prevalence of internet addiction was 43.9 %. The average age of internet-addicts was 16.34 years, the male sex was the most represented (54.1 %) and increased the risk of internet addiction (OR a=2.805). The average duration of connection among Internet addicts was 4.6hours per day and was significantly related to internet addiction; P<0.001). Socializing activities were found in the majority of the internet-addicted adolescents (86.5 %). The type of online activity was significantly associated with internet addiction (P=0.03 and OR a=3.256). Other behavioral addictions were frequently reported: 35.13% for excessive use of video games and 43.25 % for pathological purchases. These two behaviors were significantly associated with internet addiction (with respectively P=0.001 and P=0.002 with OR=3.283). The internet-addicted adolescents lived with both parents in 91.9 % of cases. The mother's regular professional activity was significantly associated with internet addiction risk (P=0.04) as was the use of the Internet by parents and siblings (with respectively P=0.002 and P<0.001 with OR=3.256). The restrictive attitude of the parents was significantly associated with internet addiction risk (P<0.001 OR=2.57). Family dynamics, particularly at the level of adolescent-parent interactions, were a determining factor in internet addiction. Anxiety was more frequently found than depression among our cyber-dependent adolescents with frequencies of 65.8 % and 18.9 %, respectively. Anxiety was significantly correlated with the risk of internet addiction (P=0.003, OR a=2.15). There was no significant correlation between depression and the risk of internet addiction. CONCLUSION: The Tunisian adolescent seems at great risk of internet addiction. Targeted action on modifiable factors, especially those affecting family interactions, would be very useful in prevention.

[Affective temperaments in drug addicts: A case-control study]. / Tempéraments affectifs des toxicomanes : étude cas-témoins.

INTRODUCTION: The study of affective temperaments is a dimensional approach to personality that would provide a better understanding of the emergence of psychopathological disorders including addictive behaviors. However, in the literature, there is a lack of studies focusing on the links between this type of disorder and affective temperaments. Our objectives were to study the distribution of the five known affective temperaments in a group of drug addicts compared to a control group, and to identify sociodemographic and clinical factors associated with emotional traits. METHODS: This was a case-control study carried out in the drug abuse prevention center "ATUPRET" of Sfax in Tunisia. It included 50 drug addicts, all male, and 50 healthy control subjects matched for age (P=0.22), marital status (P=0.28), socioeconomic level (P=0.36) and educational level (P=0.95). Sociodemographic data were collected through an interview for drug addicts hospitalized in this center while clinical data were collected from medical records. The TEMPS-A questionnaire, 110 questions validated Tunisian version, has been used to evaluate five affective temperaments. RESULTS: The average age of drug addicts was 32.98 years (19-59 years) and the average age at onset of drug use was 20.36 years (12-52 years). Among drug users, the highest mean scores were observed for hyperthymic temperament (13.68±4.20), followed by cyclothymic (13.14±4.89), anxious (11.32±6.00) and depressive (11.02±3.65) ones. The lowest mean score was for irritable temperament (10.14±3.95). All of these scores, except that of cyclothymic temperament, were significantly higher than in the control group (P<0.01). The age of drug addicts was negatively correlated with cyclothymic (P=0.023) and irritable (P=0.035) temperament scores. These two temperaments were more dominant in the group of drug addicts with post-secondary education (P respectively 0.035 and 0.002). The age of onset of psychoactive substance use was negatively correlated with irritable temperament (r=-0.355, P=0.012). Cyclothymic temperament was correlated with alcohol dependence (P=0.03) and psychiatric comorbidity (P=0.01) among drug addicts. CONCLUSION: The present study provides support for the existence of temperamental dysregulation in drug-addicted patients. This result leads us to suggest that affective temperaments are implicated as a potential endophenotype and may represent a marker for the identification of persons vulnerable to drug use. These affective temperaments also appear to influence clinical features of drug addiction.

Liver monoamine oxidase (MAO) in liver homogenate of mice infected with Schistosoma mansoni and effect of certain therapeutic agents.

MAO activity in liver homogenate of mice infected with Schistosoma mansoni was determined from the second till the 14th week following infection. Significant diminution of MAO activity was noticed starting from the sixth week following infection, reaching its lowest value at the eighth week, obviously denoting progress of hepatic fibrosis. Treatment of the infected, animals with four different antischistosomal agents, tarter emetic, stibophen, niridazole and hycanthone, resulted in an improvement of the enzyme level to an almost normal value. This may indicate the ease with which the lesions in the liver including fibrosis recover when the infection is successfully treated.
