[Thesaurus n°1] suicideMots-clés : electroconvulsive therapy schizophrenia depression mania Chinese race Résumé : Objective: Electroconvulsive therapy (ECT) was first introduced in China in the early 1950s and has evolved into a significant psychiatric treatment. Research from Chinese psychiatrists provides important clinical data for ECT practitioners. However, most of the research has only been published in Chinese language journals. This article summarizes data from publications in the Chinese scientific community related to the clinical practice of ECT and research on efficacy in the treatment of psychiatric disorders.Methods: Descriptive study primarily based on Chinese language literature identified from searches of the China National Knowledge Infrastructure and the Medline databases (1979-2012).Results: More than 900 journal papers on ECT have been published in the Chinese language between 1979 and 2012. Currently, modified ECT has replaced unmodified ECT, and treatments were performed both in inpatient and outpatient settings. Electroconvulsive therapy is primarily used for the treatment of schizophrenia and mood disorders and has been shown to be very effective in both. The primary use of ECT in China is in the treatment of schizophrenia. The Chinese literature provides a rich database on the efficacy of modified and unmodified ECT, with and without adjunctive antipsychotics, in the treatment of schizophrenia.Conclusion: The Chinese medical literature provides an important database that will help advance the practice of ECT in both China and the international community.

Titre : Canadian Survey of Perianesthetic Care for Patients Receiving Electroconvulsive Therapy Type de document : texte imprimé Auteurs : Ian Gilron ; Nicholas Delva ; Peter Graf Année de publication : 2013 Article en page(s) : 219-224 p. Note générale : Reçu le 7 Janvier 2013 Langues : Anglais (eng) Mots-clés : electroconvulsive therapy anesthesia clinical survey practice patterns Résumé : Objectives: We report on the anesthesia subsection of a comprehensive nationwide survey (Canadian Electroconvulsive Therapy Survey/Enquête canadienne sur les electrochocs) on the practice of electroconvulsive therapy (ECT) in Canada.Methods: This comprehensive survey was sent to the 175 Canadian institutions identified as providers of ECT in 2007. Among other topics, 9 anesthesia-related questions were administered regarding anesthesiology consultation; high-risk patients; credentials of the anesthesia provider; monitoring, airway, and resuscitation equipment; anesthetic induction, muscle relaxant, vasoactive, and other perianesthetic drugs and practices; and postanesthetic discharge.Results: Sixty-one percent (107/175) of the institutions returned completed survey questionnaires. More than 70% of the sites reported pre-ECT anesthesiology consultation for all (61%) or most (11%) patients. In more than 90%, a Canadian Royal College-certified anesthesiologist, or equivalent, provided anesthetic care. Routine use of oximetry, electrocardiography, and blood pressure monitoring were reported by all but 2 sites; use of bite block was reported by all but 4 sites; and preoxygenation was reported by all but 7 sites. Dantrolene and capnography were not reported as readily available by 35% and 40%, respectively, with comparatively less frequent availability at non-operating room and lower-volume sites.Conclusions: These results suggest safe practices of anesthesia for ECT in Canada. Further attention needs to be paid to ready availability of dantrolene and capnography, particularly at non-operating room ECT sites. Improvements in anesthetic care of patients undergoing ECT may be realized through continued knowledge translation efforts and by expanding access to currently unavailable anesthetic induction agents and, in some settings, limited clinical anesthesiology resources.

Titre : One-Year Follow-Up After Discontinuing Maintenance Electroconvulsive Therapy Type de document : texte imprimé Auteurs : Kaija Huuhka ; Merja Viikki ; Tarja Tammentie Année de publication : 2013 Article en page(s) : 225-228 p. Note générale : Reçu le 7 Janvier 2013 Langues : Anglais (eng) Mots-clés : continuation ECT maintenance ECT ECT MDD Résumé : Objectives: Electroconvulsive therapy (ECT) has been established as an effective method in the treatment of severe depressive or psychotic disorders. Its efficacy is greatest in severe major depressive disorder (MDD) with or without psychotic symptoms. However, maintaining remission after a successful course of short-term ECT is often difficult owing to resistance to medication in these patients. Therefore, the relapse rate after short-term ECT is high; 40% to 60% of patients relapse even with adequate antidepressant continuation therapy. The risk of relapse is greatest during the first months after discontinuation of short-term ECT. Continuation/maintenance (c/m) ECT is an option in maintaining remission, but systematic data and clinical guidelines are lacking. The point at which to discontinue this treatment has not been adequately established.Methods: Altogether 45 consecutive patients treated with c/mECT after short-term ECT to prevent relapse were followed up 1 year after discontinuation of this treatment.Results: Twenty (44%) of 45 patients relapsed during follow-up, all within the first 8 months. Patients having a diagnosis other than MDD (bipolar disorder, depressive episode type I, schizophrenia, and schizoaffective disorder) were more likely to relapse than MDD patients.Conclusions: Almost half of the patients relapsed in 1 year after discontinuation of c/mECT, most of these within the first 3 months and all within the first 8 months. The risk of relapse is greater in the patients with diagnoses other than MDD. When discontinuing c/mECT, patients should be carefully followed up; and for those at risk of relapse, even permanent mECT should be considered. To the best of our knowledge, the present study is the first to report the prognosis of patients after discontinuing c/mECT.

Titre : Comparison of Ictal Electroencephalogram Between Ultrabrief- and Brief-Pulse Right Unilateral Electroconvulsive Therapy: A Multitaper Jackknife Analysis Type de document : texte imprimé Auteurs : Prashanth Mayur ; Anthony Harris ; Chris Rennie Année de publication : 2013 Article en page(s) : 229-233 p. Note générale : Reçu le 7 Janvier 2013 Langues : Anglais (eng) Mots-clés : EEG ultrabrief-pulse width ECT spectral power peak frequency jackknife sampling Résumé : Objective: Characterization of the ictal electroencephalogram (EEG) generated during ultrabrief pulse electroconvulsive therapy (ECT) is important to progress its use in routine ECT practice particularly in indicating treatment efficacy. The study compared 2- to 5-Hz and 5.2- to 13-Hz bands of the ictal EEG signal between brief- and ultrabrief-pulse ECT.Methods: Twenty-five patients with major depression were randomized to brief- (1 millisecond [ms]) and ultrabrief-pulse (0.3 ms) right unilateral ECT. In sessions 2 to 8, when patients in either group received 6 times threshold ECT, right and left frontal ictal EEG between ultrabrief (n = 60) and brief pulse (n = 63) were compared. Electroencephalographic spectra from 2- to 5-Hz and 5.2- to 13-Hz bands in the mid and postictal phases were subjected to multitaper jackknife analysis of spectral power density (uV2/Hz) and its SD or «regularity» (uV2/Hz), peak spectral frequency (Hz), and its standard deviation (SD) or regularity (Hz). Linear mixed-effect models were used to compare the outcomes.Results: In ultrabrief ECT, spectral power density and its SD were significantly smaller within the mid seizure of both bands, whereas peak frequency and its SD were similar. Postseizure suppression of spectral power density of both bands was similar in either treatments.Conclusion: Lower spectral power densities were noted with ultrabrief-pulse ECT vis-a-vis brief-pulse ECT. However, in ultrabrief pulse ECT, regularity measures and postseizure suppression were comparable to brief-pulse ECT. Permalink : https://ch-poitiers.fr/opac_css/index.php?lvl=notice_display&id=77240

Titre : Effects of Electroconvulsive Therapy on Brain Functional Activation and Connectivity in Depression Type de document : texte imprimé Auteurs : Erik B. Beall ; Donald A. Malone ; Roman M. Dale Année de publication : 2013 Article en page(s) : 234-241 p. Note générale : Reçu le 7 Janvier 2013 Langues : Anglais (eng) Mots-clés : functional MR functional connectivity resting state depression electroconvulsive therapy Résumé : Objective: Past neuroimaging work has suggested that increased activation to cognitive and emotional tasks and decreased connectivity in frontal regions are related to cognitive inefficiency in depression; normalization of these relationships has been associated with successful treatment. The present study investigated brain function before and after electroconvulsive therapy (ECT) in patients with major depressive disorder (MDD) and demonstrated the effect of treatment on cortical activation patterns.Methods: Six ECT-naive patients with depression (mean + SD age, 39.0 + 5.4 years) were treated with ECT. Within 1 week before and 1 to 3 weeks after ECT, the patients underwent a magnetic resonance imaging session with functional magnetic resonance image scanning during working memory and affective tasks and during rest. Changes in voxelwise statistical maps of brain response to each task in regions identified to be relevant from past studies of depression were compared with changes in depression severity as measured by the Hamilton Depression Rating Score. Changes in functional connectivity between brain regions were also compared with changes in depression severity.Results: Activation during both tasks was generally found to be decreased after ECT. Remission of depression was significantly associated with reduced affective deactivation after ECT in the orbitofrontal cortex (P = 0.03). Whole-brain functional connectivity of the anterior cingulate cortex showed a consistent increase in connectivity to the right dorsolateral prefrontal cortex and posterior cingulate cortex after ECT.Conclusions: These results suggest that successful ECT for MDD is associated with decreased activation to cognitive and emotional tasks and an increase in resting connectivity.

Titre : Effects of Propofol on the Activation of Hippocampal CaMKIIa in Depressed Rats Receiving Electroconvulsive Therapy Type de document : texte imprimé Auteurs : Xiao Li ; Wei Li ; Jie Luo Année de publication : 2013 Article en page(s) : 242-247 p. Note générale : Reçu le 7 Janvier 2013 Langues : Anglais (eng) Catégories : [Thesaurus n°1] calcium Mots-clés : propofol electroconvulsive therapy depression calmodulin-dependent protein kinase type II Résumé : Objectives: The aim of this study was to investigate the effects of propofol on the activation of hippocampal calcium/calmodulin-dependent protein kinase IIa (CaMKIIa) in electroconvulsive therapy (ECT) in a rat model of depression.Methods: Sprague-Dawley rats were stressed repeatedly for 28 days to establish a depressed model. Forty depressed rats were then randomly assigned (n = 10 per group) to the depression group, propofol group (received propofol once a day for 1 week), ECT group (treated with ECT once a day for 1 week), or propofol + ECT group (treated with ECT pretreated and propofol once a day for 1 week). Their depressive state was assessed using the sucrose preference test and open-field test, whereas their learning and memory were evaluated using the Morris water maze task. The expression levels of CaMKIIa and phosphorylated CaMKIIa (pCaMKIIa) were detected by immunohistochemistry.Results: Compared with the depression group, the ECT and propofol + ECT groups had higher sucrose preference percentages and scored higher on the open-field test. The ECT group exhibited longer escape latency, shorter space exploration time, down-regulated expressions of CaMKIIa and pCaMKIIa in the hippocampus, and lower pCaMKIIa/CaMKIIa values. The propofol + ECT group showed up-regulated expressions of CaMKIIa and pCaMKIIa in the hippocampus. Compared with the ECT group, the propofol + ECT group exhibited shorter escape latency, longer space exploration time, up-regulated expressions of CaMKIIa and pCaMKIIa, and higher pCaMKIIa/CaMKIIa values.Conclusions: Propofol may potentially alleviate ECT-induced learning/memory impairment in depressed rats by enhancing CaMKIIa activation in the hippocampus.

Titre : Rethinking Restimulation: A Case Report Type de document : texte imprimé Auteurs : Laura Kranaster ; Christoph Janke ; Antje Lewien Année de publication : 2013 Article en page(s) : 248-249 p. Note générale : Reçu le 7 Janvier 2013 Langues : Anglais (eng) Mots-clés : ECT seizure threshold restimulation insufficient seizure abortive seizure Résumé : The individual time-course of the seizure threshold (ST) in electroconvulsive therapy is mostly unknown. It is assumed that a typical seizure is followed by a short refractory period and that ST increases in the long run. We hypothesize ST to be lowered immediately after the refractory period, particularly after inadequate or abortive seizures where risk for prolonged seizures is generally higher. Ketamine anesthesia does not possess pronounced anticonvulsive properties like propofol, etomidate, thiopental, or methohexital. It is therefore ideal to test such a hypothesis. We report the case of a geriatric patient with a major depressive episode, who received 5 consecutive electroconvulsive therapies with S-ketamine, all with identical right unilateral high-energy stimulation and restimulation. Whereas all primary stimulations were inadequate, all restimulations showed significantly improved seizure parameters such as midictal amplitude, maximal postictal heart rate, and average seizure energy index. In this patient, the refractory period turned out to be longer than 1 minute, and ST was lower in all 5 instances of restimulation. This ST decrease could be clinically useful in one-session restimulations. Permalink : https://ch-poitiers.fr/opac_css/index.php?lvl=notice_display&id=77243

Titre : Electroconvulsive Therapy in a Patient After Radiation Treatment of a Brain Metastasis: A Case Report Type de document : texte imprimé Auteurs : Laura Kranaster ; Carolin Hoyer ; Mathias Krisam Année de publication : 2013 Article en page(s) : 250-251 p. Note générale : Reçu le 7 Janvier 2013 Langues : Anglais (eng) Catégories : [Thesaurus n°1] cancer Mots-clés : ECT electroconvulsive therapy radiation Résumé : Major depression has a high incidence in patients with cancer, but treatment guidelines for this vulnerable population are missing and antidepressants seem to be less effective than in patients not affected by cancer. We report the case of a patient with bronchial cancer with a single temporo-occipital brain metastasis that had been treated by radiotherapy (whole-brain radiation, 40 Gy, followed by a stereotactic radiotherapy, 15 Gy). The patient developed a major depressive episode and was successfully treated with electroconvulsive therapy without relevant adverse events. This case further underscores the safety and effectiveness of electroconvulsive therapy after radiotherapy of the brain and demonstrates a viable alternative for severely depressed patients with cancer who do not adequately respond to psychotherapy or pharmacotherapy alone.
