In a single patient suffering from a major depressive episode with melancholia (DSM-III), both severe psychomotor symptoms, such as stupor and mutism, and mood disturbances could be abolished completely and promptly by administration of the benzodiazepine lorazepam. Remission of symptoms was entirely and immediately reversed by the benzodiazepine antagonist Ro 15-1788. These drug effects were constantly reproducible. Possible mechanisms of action and the influence of GABAergic neurotransmission on affective and psychomotor state are discussed. 相似文献

The relationship between psychopathology and brain alterations, measured by computed tomography (CT), was investigated in 44 depressed patients. Comparisons of ventricle-brain ratio (VBR) between "endogenous" vs. "nonendogenous" subgroups, classified by six distinct diagnostic systems, revealed no significant differences. The VBR and the width of the third ventricle correlated significantly with scores on the Brief Psychiatric Rating Scale, the Global Assessment Scale, the Bech-Rafaelsen Melancholia Scale, the Rating for Emotional Blunting, and the Scale for the Assessment of Negative Symptoms, but not with scores on the Hamilton Rating Scale for Depression and the Hamilton Rating Scale for Anxiety. Item analyses of the Bech-Rafaelsen Melancholia Scale revealed that retardation-related items were most significantly correlated with ventricular size. The wider diameter of the third ventricle in psychotic patients was associated with higher scores on retardation in the psychotic subgroup, whereas the greater distances of both Sylvian fissures showed no relationship to psychomotor retardation. No significant correlations were found between CT values and anxiety, suicidal impulses, somatic complaints, and sleep disturbances. 相似文献

Preclinical data indicated that seroquel (ICI 204 636), a dibenzothiazepine with 5-HT2 and D2-like receptor antagonistic properties, might be an effective antipsychotic agent, causing fewer extrapyramidal side effects than typical neuroleptics. In the present study, 12 patients suffering from schizophrenia or schizophreniform disorder with predominantly positive symptomatology were treated in an open clinical trial for 4 weeks with seroquel at a maximum dosage of 750 mg/day. The drug was generally well tolerated, and virtually no adverse extrapyramidal side effects such as acute dystonia, parkinsonism or akathisia were observed. Total scores for BPRS (item score 0–6; baseline: 42.0±2.3; mean±SeM), SAPS (64.5±4.8) and SANS (55.0±4.3) showed a moderate decrease at the end of treatment (BPRS: 30.0±3.5; SAPS: 36.1±6.7; SANS: 42.5±5.9), when intention-to-treat analysis was applied. There were considerable interindividual differences in treatment response, with some subjects showing almost full remission of positive symptoms, in contrast to about half of the patients who showed no satisfactory clinical improvement. Interestingly, patients showing good antipsychotic response reported slight initial side effects like mild sedation. Prolactin and TSH levels were not altered during seroquel administration. As to pharmaco-EEG investigations, seroquel caused a moderate increase of the absolute power in the alpha, theta, and beta frequency bands, paralleled by a decrease of delta activity. There were no signs of paroxysmal EEG activity under seroquel. Our results suggest that seroquel may be a well tolerated drug with some antipsychotic properties, exhibiting no extrapyramidal side effects that could be of use in the treatment of schizophrenic patients with positive symptomatology. Further double-blind studies with higher doses, in order to test presumably better efficacy, and with monitoring of plasma levels, are needed to extend the present results. 相似文献

Antipsychotic efficacy and side effects of the selective sigma ligand EMD 57445 (panamesine) were investigated in 12 patients (6 males, 6 females) who met DSM-III-R criteria for schizophrenia. A 4-week open clinical study revealed only modest effects of EMD 57445 and its metabolites on positive and negative symptoms of schizophrenia. Extrapyramidal and other side effects were moderate, although a significant increase in mild dyskinetic movements was found. Five patients, four of whom were females, completed the trial. Dropouts were mainly due to treatment failure. Antipsychotic effects were significantly greater in female than male patients. 相似文献

Zusammenfassung 32 ambulante Hämodialyse-Patienten wurden über einen Zeitraum von 8 Tagen mehrfach täglich durch psychometrische Fremd- und Selbstbeurteilungsskalen in ihrer Befindlichkeit eingeschätzt. Ziel der Untersuchung war es, depressive Verstimmungen in ihrer Häufigkeit und Ausprägung bei Hämodialyse-Patienten zu erfassen. Es sollte zudem geprüft werden, inwieweit derartige depressive Verstimmungen zur Frage der biochemischen Determiniertheit von depressiven Syndromen beitragen können. Es fanden sich subjektiv erlebte kurzfristige depressive Stimmungsschwankungen in etwa 15% der Fälle, die in den psychometrischen Fremdbeurteilungen jedoch nicht zu objektivieren waren. Derartige depressive Verstimmungen sind somit als Modelldepression für die biologische Depressions-Forschung nicht geeignet. Geringe Häufigkeit und Schwere der depressiven Verstimmungen, sowie psychopathologischer Längs- und Querschnitts-befund lassen die Hämofiltration als wesentlichen Depressionsfaktor im Sinne der Katecholamin-/Indolamin-Mangel-Hypothese unwahrscheinlich erscheinen. 相似文献

The present analysis comprises 3 studies on the interrater reliability of the Positive and Negative Syndrome Scale for Schizophrenia (PANSS; German version). To our knowledge this is the first empirical report on interrater reliability and on results of rater training of the German version of the PANSS despite the widespread use of the scale. In a total of 47 training participants with different clinical experience standardized PANSS rater training was carried out and subsequently evaluated. Therefore, concordance rates with an expert standard (C) and weighted coefficients kappa (kappa W) were calculated. As a main outcome of the studies, at least 3 training sessions were necessary but also sufficient to reach acceptable interrater reliability of the PANSS (C > 80%, kw > 0.60). In training participants with low psychiatric experience the level of interrater reliability of schizophrenic negative symptoms did not reach the results of positive symptoms after the training. Despite some conceptual limitations with respect to negative symptoms, the German version of the PANSS seems highly suitable to assess a broad spectrum of schizophrenic psychopathology in a reliable and economic manner. The present results also underline the practicability of our recommendations for conducting PANSS rater training in the clinical and scientific field as part of quality control and quality assurance in psychopathological assessment. 相似文献

AIM:To determine calprotectin release before and after colorectal cancer operation and compare it to tumor and histopathological parameters.METHODS:The study was performed on patients with diagnosed colorectal cancer admitted for operation.Calprotectin was measured in a single stool sample before and three months after the operation using an enzymelinked immunosorbent assay(ELISA).Calprotectin levels greater than or equal to 50μg/g were considered positive.The compliance for collecting stool samples was assessed and the value of calprotectin was correlated to tumor and histopathological parameters of intra-and peri-tumoral inflammation.Surgical specimens were fixed in neutral buffered formalin and stained with hematoxylin and eosin.Staging was performed according to the Dukes classification system and the 7th edition tumor node metastasis classification system.Intra-and peri-tumoral inflammation was graded according to the Klintrup criteria.Immunohistochemical quantification was performed for MPO,CD45R0,TIA-1,CD3,CD4,CD8,CD57,and granzyme B.Statistical significance was measured using Wilcoxon signed rank test,Kruskal Wallis test and Spearman’s rank correlation coefficient as appropriate.RESULTS:Between March 2009 and May 2011,80 patients with colorectal cancer(46 men and 34 women,with mean age of 71±11.7 years old)were enrolled in the study.Twenty-six patients had rectal carcinoma,29 had left-side tumors,23 had right-side tumors,and2 had bilateral carcinoma.In total,71.2%of the patients had increased levels of calprotectin before the operation(median 205μg/g,range 50-2405μg/g)and experienced a significant decrease three months after the operation(46μg/g,range 10-384μg/g,P<0001).The compliance for collecting stool samples was 89.5%.Patients with T3 and T4 tumors had significantly higher values than those with T1 and T2 cancers(P=0.022).For all other tumor parameters(N,M,G,L,V,Pn)and location,no significant difference in calprotectin concentration was found.Furthermore,the calprotectin levels and histological grading of both peri-and intra-tumoral inflammation was not correlated.Additional testing with specific markers for lymphocytes and neutrophils also revealed no statistically significant correlation.CONCLUSION:Fecal calprotectin decreases significantly after colorectal cancer operation.Its value depends exclusively on the individual T-stage,but not on other tumor or histopathological parameters. 相似文献
