Titre : Rapid Antidepressant Effect of Ketamine in the Electroconvulsive Therapy Setting Type de document : texte imprimé Auteurs : Chadi G. Abdallah ; Madonna Fasula ; Ben Kelmendi Année de publication : 2012 Article en page(s) : 157-161 p. Note générale : Reçu le 8 Octobre 2012 Langues : Anglais (eng) Mots-clés : ECT ketamine rapid antidepressant barbiturate Résumé : Objectives: Studies now provide strong evidence that the N-methyl-D-aspartate receptor antagonist ketamine possesses rapidly acting antidepressant properties. This study aimed to determine if a low dose of ketamine could be used to expedite and augment the antidepressant effects of electroconvulsive therapy (ECT) treatments in patients experiencing a severe depressive episode.Materials and Methods: Subjects with major depressive disorder or bipolar disorder referred for ECT treatment of a major depressive episode were randomized to receive thiopental alone or thiopental plus ketamine (0.5 mg/kg) for anesthesia before each ECT session. The Hamilton Depression Rating Scale (HDRS) was administered at baseline and at 24 to 72 hours after the first and sixth ECT sessions.Results: Electroconvulsive therapy exerted a significant antidepressant effect in both groups (F2,24 = 14.35, P < 0.001). However, there was no significant group effect or group-by-time interaction on HDRS scores. In addition, post hoc analyses of the time effect on HDRS showed no significant HDRS reduction after the first ECT session for either group.Conclusions: The results of this pilot study suggest that ketamine, at a dose of 0.5 mg/kg, given just before ECT, did not enhance the antidepressant effect of ECT. Interestingly, the results further suggest that the coadministration of ketamine with a barbiturate anesthetic and ECT may attenuate the immediate antidepressant effects of the N-methyl-D-aspartate antagonist.

Titre : Is the Use of Electroconvulsive Therapy Falling Because of Fewer Referrals of Patients With Severe Depression? Type de document : texte imprimé Auteurs : Allan Scott Année de publication : 2012 Article en page(s) : 162-164 p. Note générale : Reçu le 8 Octobre 2012 Langues : Anglais (eng) Mots-clés : electroconvulsive therapy (ECT) use diagnosis depression Résumé : Background: The reasons for the fall in the use of electroconvulsive therapy (ECT) in the United Kingdom have never been systematically assessed. Between 2005 and 2006, the Edinburgh clinic saw the greatest fall ever in the rate of ECT usage between consecutive years.Objective: To test the anecdotal hypothesis that this fall resulted from the referral of fewer patients with a diagnosis of severe depression (with or without psychotic symptoms) as per the International Classification of Diseases, 10th Revision. Diagnostic data from 2007 were included to aid comparison.Results: The rates of ECT usage (number of individual patients treated per 10,000 total population) were 1.33, 0.82, and 0.88 in the study years. The numbers of patients with a diagnosis of severe depression of either type were identical in the study years. The fall in the rate of ECT usage resulted mainly from fewer referred patients with a diagnosis of other mood disorders, that is, disorders that did not meet criteria for more specific diagnoses such as depressive episode or bipolar affective disorder.Conclusions: Just as many severely depressed patients were treated despite the marked fall in the rate of ECT usage.

Titre : Asystole in Ultrabrief Pulse Electroconvulsive Therapy Type de document : texte imprimé Auteurs : Jennifer M. Coughlin ; Kyle Rodenbach ; Pin-Hsuan Lee Année de publication : 2012 Article en page(s) : 165-169 p. Note générale : Reçu le 8 Octobre 2012 Langues : Anglais (eng) Mots-clés : electroconvulsive therapy ultrabrief pulse width asystole bradycardia Résumé : Objectives: Ultrabrief (UB) pulse electroconvulsive therapy (ECT) has been gaining popularity in recent years because of its improved cognitive adverse effect profile compared with treatments triggered by brief pulses. When delivered at maximal charge, UB pulses are administered for 8 seconds. Because electrical stimulation triggers a parasympathetic surge and transient asystole, we checked whether UB pulses delivered for 8 seconds were associated with prolonged cardiac pause compared with maximal charge delivered for 4 seconds with brief pulses.Methods: This is a retrospective study of cardiac pause length of all patients undergoing ECT treatment at The Johns Hopkins Hospital during 1 year.Results: Electrocardiac pause length for patients undergoing ECT with right unilateral placement at maximal charge was not affected by pulse width. However, we did find cardiac pause length to be sensitive to 2- versus 4-second duration stimuli using brief pulses (P < 0.0001).Conclusions: Notwithstanding the clear limitations of small sample size and retrospective design, we found that right unilateral ECT was not affected by pulse width when maximal charge was delivered.

Titre : Electroconvulsive Therapy in Brazil After the «Psychiatric Reform»: A Public Health Problem--Example From a University Service Type de document : texte imprimé Auteurs : Rafael Bernardon Ribeiro ; Débora Luciana Melzer-Ribeiro ; Sergio Paulo Rigonatti Année de publication : 2012 Article en page(s) : 170-173 p. Note générale : Reçu le 8 Octobre 2012 Langues : Anglais (eng) Mots-clés : ECT statistics Brazilian Public Mental Health System psychiatric reform Résumé : Objectives: The Brazilian public health system does not provide electroconvulsive therapy (ECT), which is limited to a few academic services. National mental health policies are against ECT. Our objectives were to analyze critically the public policies toward ECT and present the current situation using statistics from the Institute of Psychiatry of the University of São Paulo (IPq-HCFMUSP) and summary data from the other 13 ECT services identified in the country.Methods: Data regarding ECT treatment at the IPq-HCFMUSP were collected from January 2009 to June 2010 (demographical, number of sessions, and diagnoses). All the data were analyzed using SPSS 19, Epic Info 2000, and Excel.Results: During this period, 331 patients were treated at IPq-HCFMUSP: 221 (67%) were from São Paulo city, 50 (15.2%) from São Paulo's metropolitan area, 39 (11.8%) from São Paulo's countryside, and 20 (6.1%) from other states; 7352 ECT treatments were delivered--63.0% (4629) devoted entirely via the public health system (although not funded by the federal government); the main diagnoses were a mood disorder in 86.4% and schizophrenia in 7.3% of the cases.Conclusions: There is an important lack of public assistance for ECT, affecting mainly the poor and severely ill patients. The university services are overcrowded and cannot handle all the referrals. The authors press for changes in the mental health policies.

Titre : Repeated Electroconvulsive Seizures Increase the Number of Vessel-Associated Macrophages in Rat Hippocampus Type de document : texte imprimé Auteurs : Linda Jansson ; Karin Orre ; Anders Tingström Année de publication : 2012 Article en page(s) : 174-179 p. Note générale : Reçu le 8 Octobre 2012 Langues : Anglais (eng) Mots-clés : electroconvulsive seizures macrophage recruitment perivascular macrophages CD163 Résumé : Objectives: We have previously reported that electroconvulsive seizure (ECS)--an animal model of the antidepressant treatment electroconvulsive therapy--causes glial cell activation in hippocampus and other limbic areas. In the current study, we have investigated whether the cellular response to ECS includes recruitment and infiltration of nonresident macrophages into the hippocampal brain parenchyma.Methods: Adult rats received 1 ECS daily for 10 consecutive days and were then killed at different time points after the last ECS treatment. Brain sections were immunostained for laminin, a matrix protein expressed in the basal membrane of blood vessels, in combination with anti-CD163, which identifies mature blood-borne macrophages. The number of CD163+ cells in the hippocampus was quantified. We also investigated the number of vessel-associated cells expressing CD4 and major histocompatibility complex class II (MHC II). CD4 is mainly expressed by CD4+ T cells, but can also be found on macrophages, monocytes, and activated microglia, whereas MHC II is expressed by macrophages, activated microglia, dendritic cells, and B cells.Results: Our results demonstrate increased numbers of CD163+ and CD4+ cells following ECS. Most CD4+ cells within the vasculature had a similar morphology to the CD163+ macrophages. No CD163+ cells were detected outside the vessels but a subpopulation of CD4+ cells was seen in the brain parenchyma, here with a morphology resembling microglia. There was a transient increase in the number of blood vessel-associated MHC II+ cells following ECS.Conclusions: Our observations showed that the cellular response to ECS involves recruitment of blood-derived macrophages, but we could not see any infiltration into the brain parenchyma of these cells.

Titre : Tardive Seizure With Postictal Aphasia: A Case Report Type de document : texte imprimé Auteurs : W Carson Felkel ; Gerhardt Wagner ; James Kimball Année de publication : 2012 Article en page(s) : 180-182 p. Note générale : Reçu le 8 Octobre 2012 Langues : Anglais (eng) Mots-clés : electroconvulsive therapy tardive seizure adverse event Résumé : Electroconvulsive therapy (ECT) is a highly effective treatment for certain psychiatric disorders with relatively few serious adverse effects or complications. Tardive seizures are one of these rare but potentially fatal complications. Recognizing and treating tardive seizures is essential to prevent prolonged postictal confusion, progression to status epilepticus and associated soft tissue injury, anoxia, aspiration, and death. Currently, there is an unknown prevalence of their occurrence and an overall lack of clinical description of their phenomenology. We describe a case in which a patient develops a tardive seizure followed by a receptive and expressive aphasia, thought to be a variant of Todd's postictal paralysis. This case is further unique in that there was a lateralization of a motor seizure presumably to the hemisphere contralateral to the right unilateral electrode placement.

Titre : Flumazenil Pretreatment in Benzodiazepine-Free Patients: A Novel Method for Managing Declining ECT Seizure Quality Type de document : texte imprimé Auteurs : James Yi ; Jonathan Torres ; Yuval Azner Année de publication : 2012 Article en page(s) : 185-189 p. Note générale : Reçu le 8 Octobre 2012 Langues : Anglais (eng) Mots-clés : ECT major depressive disorder flumazenil seizure threshold elderly Résumé : Objective: Seizure threshold increases with successive electroconvulsive therapy (ECT) treatments, which can be especially problematic when treating older patients who have higher seizure thresholds at baseline because ECT devices are limited by the amount of charge that can be delivered.Case Reports: We present a case series of 3 older patients who had long ECT courses that were complicated by inability to generate seizures, poor quality seizures, and inadequate clinical response despite established measures to lower seizure threshold including prehydration, hyperventilation, and minimizing methohexital dose using remifentanil. As preclinical studies show electroconvulsive seizure increases diazepam binding, we hypothesized that a contributor to declining seizure quality and inadequate ECT responsiveness in these individuals was enhanced benzodiazepine receptor function, although none of the 3 patients were taking benzodiazepines or any other anticonvulsant medication. Accordingly, we pretreated patients with flumazenil, a competitive inhibitor at the benzodiazepine-binding site, and observed improvement in seizure quality and clinical response.Conclusion: Flumazenil pretreatment of elderly ECT patients with declining seizure quality and inadequate clinical response in the setting of repeated treatments may represent a novel strategy for managing such patients. A clinical trial would be required to test this hypothesis. Permalink : https://ch-poitiers.fr/opac_css/index.php?lvl=notice_display&id=75982

Titre : Brain-Behavior Relationship in a Case of Successful ECT for Drug Refractory Catatonic OCD Type de document : texte imprimé Auteurs : Griodano D'Urso ; Antonio Mantovani ; Ludovica Labruna Année de publication : 2012 Article en page(s) : 190-197 p. Note générale : Reçu le 8 Octobre 2012 Langues : Anglais (eng) Mots-clés : brain lateralization brain stimulation brain imaging neurological soft signs mind-brain relationship Résumé : his case report describes the successful response to electroconvulsive therapy (ECT) in a patient with an unusual presentation of catatonia, whose onset occurred in the context of an extremely severe form of refractory obsessive-compulsive disorder (OCD). We correlated the clinical improvement in catatonic and OCD symptoms with specific changes in brain function as shown by regional cerebral blood flow scans, neurological soft signs examination, and neuropsychological testing. All assessments were conducted before and after the ECT course. The results strongly suggest that a right hemisphere dysfunction was the neural correlate of our patient's symptoms, and that ECT, by reverting this abnormality, may serve as an effective therapeutic approach for refractory catatonic OCD.
