The high rate of benzodiazepines (BZD) consumption has been repeatedly confirmed by epidemiological surveys in most major western world countries. In a recent french survey 7% of chronic users of BZD (use in 5/7 days for the last 12 months) were found the general population (17% in the population aged above 65). It has been suggested that the high BZD consumption rate could be related to dependence. The existence of BZD dependence was described in the early sixties with very high dose of chlordiazepoxide but it has become a real concern for the medical community since the late seventies with increasing number of reports of withdrawal symptoms. The extend of the actual rate of withdrawal symptoms at BZD tapering is still very controversial and according to the different studies it varies from 39 to 90%. The between studies difference in parameters such as: the patient populations (psychopathology, treatment duration), the type of tapering employed (duration, nature of the medical and psychological support) and the used operational criteria for withdrawal definition most likely explain this wide variation in the rate of occurrence of withdrawal manifestations. According to the American Psychiatric Association Task Force on Benzodiazepine Dependence, Toxicity and Abuse three type of pathological events can happen after treatment discontinuation: rebound, withdrawal syndrome and recurrence. The rebound consists in the early and transitory reappearance of the anxiety symptoms pre-existing to the treatment but in an exacerbated from; the withdrawal syndrome associates the resurgence of the pre-existing anxiety symptoms and new symptoms as sensory disturbances (metallic taste, hyperosmia, cutaneous exacerbated sensitivity, photophobia...) nausea, headache, motor disturbance in some rare cases depersonalization, paranoid reaction, confusion, convulsion. Rebound or withdrawal syndrome appearance delay varies from hours to few days according mostly to compounds elimination half-life. The relapse develops later with a progressive reapparance of pre-treatment symptoms. In practice recurrence and rebound are often difficult to isolate: recurrence can follow rebound. Different operational criteria of definition for this different entities have been proposed but there is a need for a consensual position. The treatment length, a high daily dose, an alcohol abuse history, a dependent personality and the severity of the psychopathology of the patients have been found to be predictive for the occurrence of withdrawal symptoms. Behavioural therapies (individual or in group) have been proposed with some success for the treatment of benzodiazepine dependence; drug treatment with carbamazepine or imipramine have demonstrated some efficacy. Other drug as buspirone clonidine having anxiolytic properties have not demonstrated efficacy.(ABSTRACT TRUNCATED AT 400 WORDS)

The impact of substance abuse on patients with borderline personality disorder was investigated. Substance abuse was common. Female patients preferred alcohol and sedatives. Male patients preferred stimulants. Substance abuse was associated with poor school performance, unemployment, and promiscuity. Depersonalization-derealization was common in nonsubstance using and alcohol-sedative using patients, but was rarely found in stimulant users. Substance abuse appears to be a devastating complication in the patient with borderline personality disorder.

The authors prospectively assessed symptoms induced by the interruption of antidepressants in 16 patients (11 women and 5 men), aged from 33 to 85 years (mean = 52.4 +/- 16.4), treated with antidepressants since at least two weeks. All patients were free of alcohol abuse or dependence disorder and of other dependence to psychoactive substances. None of them presented medical illness. Diagnosis were made by separate evaluations by two authors and confirmed with a semistructered assessment instrument: the Schedule for Affective Disorders and Schizophrenia (Lifetime Version). All patients were submitted to a brutal discontinuation of their antidepressant agent. Patients were assessed twice, before the interruption of the antidepressant, and 72 hours later. Effects of antidepressant interruption were assessed by several means. Modification of anxiety and depression were evaluated using the Montgomery Asberg Depression Rating Scale (MADRS) and the Hamilton Anxiety Scale. Symptoms of withdrawal were assessed with Cassano and al.'s scale SESSH including an evaluation of anxiety, agitation, irritability, anergy, difficulty on concentrating, depersonalization, sleep and appetite disorders, muscle pains, nausea, tremor, sweating, altered taste, hyperosmia, paresthesias, photophobia, motor incoordination, dizziness, hyperacousia pain, delirium. Fourteen of the 16 patients (87.5%) presented modifications of their somatic or psychic state 3 days after the interruption of the antidepressant treatment. Most frequent symptoms were: increase in anxiety (31%), increase in irritability (25%), sleep disorders (19%), decrease of anergia and fatigue (19%). Mean scores of anxiety and depression were not significantly modified by the withdrawal. Following TCAs interruption (7 patients) most frequent symptoms were sleep disorders; increase in anxiety, nausea. Among patients withdrawn from SSRIs (6 patients), most frequent symptoms were increase in anxiety, increase in irritability, headache. Patients also presented a decrease of nausea, and of anorexia.

The definition of burn-out the most often cited and proposed by Maslach and Jackson, clarifies the three cardinal symptoms affecting doctors, namely, emotional exhaustion, with depersonalization of their patients and reduction of the feeling of personal accomplishment. The causes of this phenomenon are relatively well-known: individual psychological factors, stressful factors intrinsic to the medical practice and finally extrinsic factors related to the professional environment and its organization. The purpose of this review is to estimate the prevalence of burnout within the population of Belgian family physicians and to understand both individual and societal consequences. About the method. This is a literature review using databases Medline, Cochrane Library, and the American Psychological Association from 2000 to 2011 with the keywords: primary health care, family practice, burnout, emotional exhaustion, psychological stressors, distress, fatigue, depersonalization, substance and alcohol abuse, depression, well-being, quality of life, job satisfaction, professional efficiency, patient care, physician-patient relations, medical errors, quality of health care, pharmaceutical/health expenditure/statistics-numerical data, obstacles to prevention, health system assessment, medical demography. Selecting of the most relevant articles through the reading of abstracts and then full text reading of 49 selected articles. In conclusion, the exact prevalence of burn-out amongst Belgian general practitioners is not known. From some works, it is estimated that about half of them would be achieved at least in terms of emotional exhaustion. The symptoms related to burn-out are potentially serious: ea depression, alcohol and tobacco abuse and cardiovascular complications. There are also arguments demonstrating the fact that this disorder amongst general practitioners influences negatively the quality of care, their cost, but also medical demography of primary care with as a corollary a questioning of the viability of the health care system as we know it. At the time of writing this article, the Belgian Health Care Knowledge Centre (KCE) is completing, at the request of the Belgian Ministry (SPF) of Health a study entitled "Burn Out of General Practitioners: which prevention, which solutions" whose goal is to make recommendations for the prevention and support of this issue. To measure the real impact of the solutions eventually implemented, we need to create a tool for a regular assessment of the prevalence of this problem in our country.

Data suggest military personnel involved in U.S. military initiatives in Iraq and Afghanistan are returning from deployment with elevated rates of mental health diagnoses, including posttraumatic stress disorder (PTSD). The aim of this study was to examine difficulties with emotion regulation as a potential contributory mechanism by which soldiers have poorer psychological outcomes, such as depression, dissociation, alcohol abuse, and interpersonal difficulties. Participants were 44 active-duty male service members who comprised three groups, including those deployed with and without diagnosed PTSD and those prior to deployment. Participants in the PTSD group scored significantly higher on measures of self-reported depression, trauma-related dissociation, alcohol misuse, and social adjustment difficulties than did comparison groups. Importantly, difficulties with emotion regulation were found to partially mediate the relationship between PTSD and depression, poor social adjustment, and trauma-related depersonalization but not alcohol misuse. Emotion-regulation difficulties are important to consider in the relationship between PTSD and additional psychological outcomes in recently deployed personnel. Implications for treatment are briefly discussed.
