[Hemodynamic instability and long-term lithium therapy]

International audienceLithium is known to be responsible for many adverse events on the cardiovascular system. Among these events, it was experimentally noted that lithium could block the action of catecholamines on myocardium. The authors report the case of a patient under lithium therapy developing a myocardial infarction secondarily complicated of a severe cardiac failure. The inotropic support essential to balance hemodynamic could be raised only after lithium's stop. This example could be a clinical translation of the experimental effect previously observed

A case of agitated catatonia.

International audienceAgitation is one of the diagnostic features of catatonia in the DSM IV classification, but permanent forms of agitated catatonia have occasionally been described. We report the case of a 43-year-old man who had already suffered from undifferentiated schizophrenia for 7 years, and in whom we diagnosed agitated catatonia. While our patient was being treated with a neuroleptic during a second episode of paranoia, a state of agitation was observed which persisted for a further 8 months. During this period, he was treated with several different neuroleptics and benzodiazepines, either alone or in association, without any improvement. No organic cause was found. He was then transferred to our electroconvulsive therapy (ECT) unit, with a diagnosis of schizophrenic agitation resistant to drug therapy. ECT was begun, and he was only given droperidol in case of agitation and alimemazine for insomnia, neither of which had any effect. In view of his persistent agitation without any purpose, echolalia and echopraxia, stereotyped movements with mannerisms and marked mimicking and grimacing, we diagnosed him as having agitated catatonia. After the fourth session of ECT, we decided to stop all treatment and gave him lorazepam at a dose of 12.5 mg daily. Twenty-four hours later, all symptoms of agitation had disappeared. In our opinion, permanent catatonic agitation is not rare. In our case, the neuroleptic treatment maintained and may even have worsened the symptomatology. Lorazepam can be used as a therapeutic test for this type of agitation, especially if it does not respond to neuroleptics. This also allows the patient to be sedated rapidly and effectively, thus preventing him from injuring himself further

Conduites addictives, psychotraumatisme et accidents de la route

International audienceHuit à quarante pour cent des sujets confrontés à un accident de la voie publique présentent un état de stress post-traumatique. En plus de son retentissement social, familial, professionnel et fonctionnel, ce trouble présente une comorbidité importante avec les addictions. Nous présentons les résultats d'une étude prospective épidémiologique d'une population de 273 patients victimes d'un accident de la route hospitalisés en Traumatologie et suivis sur six mois

Supervised injection services : what has been demonstrated? A systematic literature review

BACKGROUND: Supervised injection services (SISs) have been developed to promote safer drug injection practices, enhance health-related behaviors among people who inject drugs (PWID), and connect PWID with external health and social services. Nevertheless, SISs have also been accused of fostering drug use and drug trafficking. AIMS: To systematically collect and synthesize the currently available evidence regarding SIS-induced benefits and harm. METHODS: A systematic review was performed via the PubMed, Web of Science, and ScienceDirect databases using the keyword algorithm [("supervised" or "safer") and ("injection" or "injecting" or "shooting" or "consumption") and ("facility" or "facilities" or "room" or "gallery" or "centre" or "site")]. RESULTS: Seventy-five relevant articles were found. All studies converged to find that SISs were efficacious in attracting the most marginalized PWID, promoting safer injection conditions, enhancing access to primary health care, and reducing the overdose frequency. SISs were not found to increase drug injecting, drug trafficking or crime in the surrounding environments. SISs were found to be associated with reduced levels of public drug injections and dropped syringes. Of the articles, 85% originated from Vancouver or Sydney. CONCLUSION: SISs have largely fulfilled their initial objectives without enhancing drug use or drug trafficking. Almost all of the studies found in this review were performed in Canada or Australia, whereas the majority of SISs are located in Europe. The implementation of new SISs in places with high rates of injection drug use and associated harms appears to be supported by evidence

Stressful life events and pemphigus.

International audienceBACKGROUND: Stress might be a triggering factor causing pemphigus. We studied 11 consecutive cases of pemphigus over 5 years. OBJECTIVE: Studying and looking for a link between severe life events and the history of the disease. METHODS: An epidemiological retrospective and prospective study was carried out, including an interview and a collection of the clinical history; then the life events were integrated into the clinical history with the patient blind. Two scales were used: Paykel's inventory (assessing the negative impact of life events) and the Mini International Neuropsychiatric Interview DSM-IV (MINI). RESULTS: 10 patients out of 11 were included. With the MINI, 2 patients presented anxiety. Paykel's inventory showed type 3 life events for numerous patients, life event type 4 for 7 patients and type 5 for 3 patients, happening from 1 to 6 months before the first signs or worsening of pemphigus. We found stressful life events before the start or worsening of pemphigus for all patients with no other risk factors. CONCLUSION: Stressful life events can worsen or trigger off a pemphigus. Psychological care, associated with the immunosuppressive treatment, should entail a better management of these patients
