Knowledge of Tunisian physicians about electronic cigarettes.

INTRODUCTION: The electronic cigarette is a new-generation smoking product whose mechanism of use could, in theory, minimize adverse health effects. AIM: Determine the knowledge and perceptions of a sample of Tunisian doctors regarding electronic cigarettes. METHODS: We conducted a descriptive cross-sectional study over a two-month period with a sample of Tunisian doctors. We used an online self-questionnaire on physicians' knowledge and perceptions of e-cigarettes. RESULTS: Data were obtained from 216 physicians. Of the participants, 97.2% were familiar with e-cigarettes, 56.5% reported low knowledge, and 83.4% expressed motivation to learn more about e-cigarettes. Overall, 83.8% of doctors felt that electronic cigarettes are harmful to the user's health. Use of this product would increase the risk of cancer according to 73.1% of participants, the risk of cardiovascular disease according to 68.5% of participants, and the risk of chronic lung disease according to 79.2% of participants. The perception of e-cigarettes as harmful to the user's health was associated with the physicians' medical specialty (p=0.032). The recommendation of e-cigarettes as a smoking cessation tool was negatively correlated with addictology training (p=0.027). CONCLUSIONS: Physicians' knowledge of electronic cigarettes is heterogeneous, reflecting the current lack of information and consensus.

Charles Bonnet Syndrome Related to a Pituitary Adenoma: A Case Study in a Tunisian Woman.

According to the International Statistical Classification of Diseases and Related Health Problems 11th Revision (ICD-11) definition, "Charles Bonnet Syndrome" (CBS) refers to the experience of complex visual hallucinations in a person who has experienced a partial or complete loss of vision. Pituitary adenoma is a rare situation that may be associated with CBS. We report a case of CBS in a Tunisian 44-year-old female with pituitary macroadenoma. The patient reported visual hallucinations which persisted after transsphenoidal adenomectomy. She had no prior psychiatric history. She did not take any medication that could produce hallucinations. After Olanzapine initiation, hallucinations were completely resolved. It is the first Tunisian case of CBS reported in English language. This peculiar condition seems to be under-recognized in our country. Clinicians should be aware that visual hallucinations may concern patients without psychiatric disorders.

Incidence of treatment-resistant depression during the first mood depressive episode.

INTRODUCTION: In spite of several approaches and therapeutic measures, treatment-resistant depression (TRD) continues to inflict serious, individual and collective consequences. Therefore, there is a persistent need to scrutinize the concept of TRD in order to adapt the therapeutic strategies. AIM: To estimate the incidence of TRD in patients with a first major depressive episode (MDD), and study factors associated with resistance. METHODS: A descriptive prospective longitudinal study of outpatients with a first MDD, was conducted. Patients with a history of subthreshold hypomania were excluded. Eligible patients were put on a selective serotonin reuptake inhibitor (SSRI), either fluoxetine or sertraline. Participants were followed regularly until they had a therapeutic response or they met the criteria for TRD. RESULTS: The study involved 82 adults. The incidence of treatment-resistant depression was 19.4% CI95%=[5.5-33.3]. Among the sociodemographic and clinical factors, family history of psychosis (p=0.038) and chronic respiratory comorbidities (p=0.016) were associated with TRD. The small size of the sample is a potential limitation of this study. Besides, the use of only two SSRIs could influence the results. CONCLUSION: In this study, the incidence of TRD was at the lower limit of the rates reported in clinical studies. Clinical factors associated with TRD suggest the relevance of genotype analysis to identify patients with TRD. Furthermore, our results highlight the importance of heeding comorbidities to optimize care. Larger multicenter studies are needed to generalize.

The first Tunisian case of postorgasmic illness syndrome: A case report.

Postorgasmic illness syndrome (POIS) is a rare and singular syndrome. About fifty cases have been reported in the medical literature. Through a clinical observation, we illustrate the first case diagnosed in Tunisia and the difficulties in the etiological diagnosis and the therapeutic management of this syndrome. Given the shortage of cases reported in the literature, the syndrome of POIS remains poorly identified and subsequently misdiagnosed. The clinical diagnosis is relatively simple, yet etiological and therapeutic questions remain to overcome.

Correlates of benzodiazepine dependence in patients with depression followed up in a psychiatric outpatient unit in Tunisia.

Benzodiazepines may be prescribed to manage anxiety and insomnia in patients with depression. However, as noticed during our daily practice, a considerable proportion of patients treated for depression and receiving benzodiazepines developed a dependence to these medicines. Our aims were to estimate the proportion of patients with depression who develop a benzodiazepine dependence and to identify its correlates. We conducted a comparative study in Razi Hospital's outpatient psychiatry unit (Tunisia). We included patients aged 18 to 65 years who were diagnosed with depression during the first three quarters of 2014. Included patients were prescribed benzodiazepines. Follow-up period was of 2 years. A multivariate analysis was performed to identify dependence-associated factors. We included 54 patients, and 52% developed a benzodiazepine dependence during the follow-up period. Two associated factors were identified: a daily mean benzodiazepine dose of more than 9.5 milligrams of diazepam equivalents prior to taper off (p = .001) and a benzodiazepine taper-off initiated after the fifth week of benzodiazepine intake onset (p = .007). The proportion of patients who developed a benzodiazepine dependence was high. Low doses and time-limited benzodiazepine prescription should be taken into consideration when managing patients with depression in order to prevent dependence.

[Clinical and evolutionary characteristics of bipolar disorder according to the polarity of the first episode]. / Aspects cliniques et évolutifs du trouble bipolaire en fonction de la polarité du premier épisode. A propos de 38 cas.

BACKGROUND: The polarity of the inaugural episode seems to determine the clinical and evolutionary profile of bipolar disorder. AIM: To study the clinical and evolutionary characteristics bipolar disorder according to the polarity of the first episode. METHODS: We undertook a retrospective, descriptive and comparative study including all the patients reached of bipolar disorder I and II (DSM IV TR) who were hospitalized between January 1 2000 and December 31 2006. The minimal duration of follow-up was 4 years. Patients were divided into two groups according to the polarity of the first episode: maniac or hypomaniaque and depressive. The characteristics sociodemographic, clinical, evolutionary and therapeutic were raised and compared between the two groups. RESULTS: The sample was composed of 38 patients (23 men and 15 women). The first episode was of polarity maniac in 57.89% of cases. This mode of beginning was related to a later polarity preferentially maniac, more often punctuated of characteristics psychotics with a sur representation of the addictives conduits and bipolar disorder of type I an episode index of depressive polarity was associated to more chronic evolution, marked by a stronger recurrence of episodes particularly depressive episodes, with a raised suicidal risk and a high representation of the bipolar disorder II. CONCLUSION: The clinical and evolutionary profile of the bipolar disorder seems strongly related to the polarity of the first episode. The strategies of prevention must take account of the inaugural polarity.

[Offensive and criminal acts in schizophrenia: comparative study according to gender]. / Actes délictuels et criminels dans la schizophrénie: étude comparative selon le genre.

BACKGROUND: Schizophrenia does not involve the same risk of violence among women than men. The offensive and criminal acts were less studied in women. AIMS: To raise the sex ratio of the criminal acts and to seek the characteristics and the risk factors of this female violence. METHODS: We carried out a comparative descriptive retrospective study, including 107 patients having schizophrenia according to criteria's of the DSM IV, hospitalized due to insanity according to article 38 of the Tunisian Penal Code. RESULTS: The sex ratio was 1 woman for 10 men. The women were older at the time of the offence or criminal act (46 years, 39 years), men were more often unmarried or divorced (50% vs 89.7%) and had more psychiatric family history (30% vs 40,2%). The duration of untreated psychoses was longer among women (65.3 months vs 22.4 months). The women more often made homicides or attempts of homicides (70%, 33%), the infanticides were raised only among women and arsons were noted only among men. The hospitalization was significantly longer among women (18.8 monthsvs 11.2 months). CONCLUSION: The preventive of offence and criminal acts in schizophrenia is also necessary among women as men.

Acute psychosis under efavirenz in a HIV patient.

BACKGROUND: Efavirenz is one of the most prescribed HIV drugs, it can have number of psychiatric adverse effects varying from sleeping disorders to psychotic symptoms. AIM: Through a case-report study we tried to evaluate the imputability of an acute psychosis to Efavirenz. CASE: Mr. B is 25-year-old, he had hemophilia A, he has been infected by HIV and HVC during one of the transfusion sessions. He'd had Combined therapy, component of Epivir, Zerit and Efavirenz. Three months after Efavirenz's prescription he presented a schizophreniform disorder according to DSM IV criteria. The onset of psychotic manifestations, 3 months after prescription is not in favor of drug's etiology. Neuropsychiatric side effects generally appear rapidly after the first dose and usually decrease during the first four months. Psychotic disorders are generally rare. However those side effects have been reported 03 years after drug introduction. CONCLUSION: Such information has an impact on drug prescription. In fact, efavirenz had been stopped, although the improvement of CD4 and the difficulty to prove the imputability of psychotic syndrome to efavirenz.
