Anterior limbic alpha-like activity: a low resolution electromagnetic tomography study with lorazepam challenge
Summary Objective To verify findings of an independently regulated anterior limbic alpha band source. Methods In a randomised cross-over study, the spontaneous EEG was recorded in nine healthy subjects after i.v. lorazepam or placebo. Intracerebral current densities within classical frequency bands were estimated with low resolution electromagnetic tomography [LORETA] and compared between groups with t -statistical parametric mapping [SPM{ t }]. A region-of-interest [ROI] based method was used to compare frontal and occipital alpha band activity changes. Results Irrespective of treatment group, local maxima of alpha band power were localised both in the occipital lobe, Brodman area [BA] 18,…
[ 18 F]Fluoroethylflumazenil: a novel tracer for PET imaging of human benzodiazepine receptors
5-(2'-[18F]Fluoroethyl)flumazenil ([18F]FEF) is a fluorine-18 labelled positron emission tomography (PET) tracer for central benzodiazepine receptors. Compared with the established [11C]flumazenil, it has the advantage of the longer half-life of the fluorine-18 label. After optimisation of its synthesis and determination of its in vitro receptor affinities, we performed first PET studies in humans. PET studies in seven healthy human volunteers were performed on a Siemens ECAT EXACT whole-body scanner after injection of 100-280 MBq [L8F]FEF. In two subjects, a second PET scan was conducted after pretreatment with unlabelled flumazenil (1 mg or 2.5 mg i.v., 3 min before tracer injection). A t…
Medikamente zur Behandlung von Persönlichkeitsstörungen
Die Therapie von Personlichkeitsstorungen war lange Zeit ausschlieslich eine Domane psychotherapeutischer Interventionen. Mittlerweile existieren einige kontrollierte Studien auch zum Einsatz von Psychopharmaka bei Personlichkeitsstorungen Die Ergebnisse sind aber fur allgemeine Empfehlungen noch zu wenig abgesichert. Die Diagnose von Personlichkeitsstorungen (z. B. Achse-Il-Storungen nach DSM-IV) ist fehleranfallig. Die diagnostischen Kategorien sind uneinheitlich und derzeit noch im Flus; selbst strukturierte Interviews erfahrener Untersucher zeigen nur begrenzte Verlaslichkeit. Wichtig ist die Erfassung und — wenn moglich — Abgrenzung von gleichzeitig vorhandenen Achse-I-Storungen nach D…
Medikamente zur Phasenprophylaxe affektiver Psychosen und zur Behandlung manischer Syndrome
Folgende Substanzgruppen sind in der Therapie manischer Syndrome und/oder in der Phasenprophylaxe affektiver Storungen etabliert (Im folgenden werden die Begriffe affektive bzw. schizoaffektive „Storung“ bzw. „Psychose“ weitgehend synonym verwendet.)
Symptom-Triggered versus Standard Chlormethiazole Treatment of Inpatient Alcohol Withdrawal: Clinical Implications from a Chart Analysis
To evaluate clinical effectiveness and safety of 2 different detoxification treatment protocols, a chart analysis of hospital inpatients consecutively admitted for alcohol withdrawal during one year was undertaken. Records of 33 patients receiving symptom-triggered treatment (using a modified version of the revised Clinical Institute Withdrawal Assessment for Alcohol Scale) were compared with those of patients treated by applying a fixed-dose regimen (n = 32). Patients (45.3 ± 9.8 years, 21% female) of both groups were comparable regarding illness severity, epidemiologic parameters as well as complications during the observed treatment period. Under symptom-triggered therapy, chlormethiazol…
