Abstract
INTRODUCTION Standardized consensus criteria for remission in schizophrenia were recently proposed. As yet, the validity of these criteria and their comparability with previously used outcome measures are unclear. METHODS The symptom-severity component of the proposed remission criteria was applied to 288 inpatients who fulfilled the ICD-10 criteria for schizophrenia. Global functioning and psychopathological symptoms were assessed using GAF, PANSS, SANS, HAM-D and CDSS. RESULTS When patients with symptom remission at discharge from hospitalization (n=158, 54.9%) were compared to those without symptom remission, significant differences were found with respect to the global functioning (GAF) and all observed psychopathological symptom dimensions. The percentage agreement with previously used outcome measures ranged between 52.6 and 80.0%, the kappa values between 0.120 and 0.594. A moderate accordance (kappa value: 0.495) was found with a Clinical Global Impression (CGI) severity score of three or less. DISCUSSION The results indicate a high descriptive validity of the symptom-severity component of the proposed remission definition. However, the new criteria differ partially from previously used outcome measures. This aspect should be considered in the interpretation of clinical trials.

Abstract
The defining clinical features of acute and transient psychotic disorders (ICD-10: F23) are an acute onset and a duration of psychotic symptoms not exceeding 1-3 months. Previous empirical investigations show that patients with this diagnosis have a favourable prognosis, but also a high risk of relapses (58-77%). The diagnostic stability in the further course of illness seems to be low (34-73%) with a frequent diagnostic change to schizophrenia and affective disorders being observed. As yet, data from controlled clinical trials regarding therapy do not exist. The implications for the treatment of acute and transient psychotic disorders are discussed with this background.

Abstract
BACKGROUND Working memory as a part of higher-order executive functions is defined by the parallel storage and processing of information. Recent functional fMRI studies have revealed a functional, interregional disintegration of a neuronal network connecting cortical, subcortical and cerebellar regions in schizophrenic patients (SZ). Cognitive impairment in working memory is a core psychopathological correlate of schizophrenic symptoms. Atypical neuroleptics such as quetiapine have shown good efficacy in treating positive and negative symptoms. The presented study evaluated the impact of a neuroleptic steady state treatment with quetiapine on the altered working memory activation patterns in schizophrenia. METHODS Patients were examined by fMRI at baseline and after 12 weeks of steady state treatment with quetiapine. Matched healthy controls (HC) underwent baseline examination. In the scanner, stimuli were presented in a 2-back and 0-back condition of a working memory (wm) paradigm, whereby a degraded and a non-degraded version were used each time. Additionally, behavioural responses (reaction time to target stimuli and error ratio) were measured. RESULTS At baseline, healthy controls revealed increased activity in the frontal lobe, especially in regions of the prefrontal cortex. Compared to HC, SZ showed hypoactivation in the right dorsolateral prefrontal cortex (DLPFC) and the ventrolateral prefrontal cortex (VLPFC) bilaterally for the 2-back condition. In the 2-back degraded condition there was a hypoactivation in both, the right DLPFC and the VLPFC. Additionally, patients showed bilaterally decreased activation in the basalganglia in the 2-back and in the right caudatus in the 2-back degraded condition compared to healthy controls. After treatment with quetiapine, patients activations patterns were increased. The pre-post comparison of the 2-back condition revealed a significant increase of activation in the left VLPFC at a significance level of 0.001 (uncorrected). The 2-back degraded condition led to a significant activation pattern in the lingual gyrus and the right precuneus. In both wm conditions, at baseline there were no differences in reaction time but only a worse performance in SZ. After treatment, behavioural measurement of responses, including reaction time and performance, showed slight improvements in SZ, although these did not reach statistical significance. CONCLUSIONS The neuronal networks underlying working memory are clearly altered in schizophrenia. After 12 weeks of treatment with quetiapine monotherapy, patients showed significant clinical improvement and revealed increased BOLD activity in the VLPFC during a working memory task, although there was no improvement of cognitive performance.

Abstract
Signs of an inflammatory process, in particular increased pro-inflammatory cytokines and increased levels of prostaglandine E(2) (PGE(2)), have repeatedly been described in major depression (MD). As cyclooxygenase-2 (COX-2) inhibitors inhibit the PGE(2) production and the production of pro-inflammatory cytokines, we performed a therapeutic trial with the COX-2 inhibitor celecoxib. In a prospective, double-blind, add-on study, 40 patients suffering from an acute depressive episode were randomly assigned to either reboxetine and celecoxib or to reboxetine plus placebo. After a wash-out period, 20 patients received 4-10 mg reboxetine plus placebo and 20 received reboxetine plus 400 mg celecoxib for 6 weeks. The treatment effect was calculated by analysis of variance. There were no significant differences between groups in age, sex, duration or severity of disease or psychopathology, or reboxetine dose or plasma levels. Over 6 weeks, both groups of patients showed significant improvement in scores of the Hamilton Depression Scale. However, the celecoxib group showed significantly greater improvement compared to the reboxetine-alone group. Additional treatment with celecoxib has significant positive effects on the therapeutic action of reboxetine with regard to depressive symptomatology. Moreover, the fact that treatment with an anti-inflammatory drug showed beneficial effects on MD indicates that inflammation is related to the pathomechanism of the disorder, although the exact mechanisms remain to become elucidated.
