BACKGROUND: Evidence regarding the different treatment options of status epilepticus (SE) in adults is scarce. Large randomized trials cover only one treatment at early stage and suggest the superiority of benzodiazepines over placebo, of intravenous lorazepam over intravenous diazepam or over intravenous phenytoin alone, and of intramuscular midazolam over intravenous lorazepam. However, many patients will not be treated successfully with the first treatment step. A large randomized trial covering the treatment of established status (ESETT) has just been funded recently by the NIH and will not start before 2015, with expected results in 2018; a trial on the treatment of refractory status with general anesthetics was terminated early due to insufficient recruitment. Therefore, a prospective multicenter observational registry was set up; this may help in clinical decision-making until results from randomized trials are available. METHODS/DESIGN: SENSE is a prospective, multicenter registry for patients treated for SE. The primary objective is to document patient characteristics, treatment modalities and in-house outcome of consecutive adults admitted for SE treatment in each of the participating centres and to identify predictors of outcome. Pre-treatment, treatment-related and outcome variables are documented systematically. To allow for meaningful multivariate analysis in the patient subgroups with refractory SE, a cohort size of 1000 patients is targeted. DISCUSSION: The results of the study will provide information about risks and benefits of specific treatment steps in different patient groups with SE at different points of time. Thus, it will support clinical decision-making and, furthermore, it will be helpful in the planning of treatment trials. TRIAL REGISTRATION: DRKS00000725.

We tested whether stereotypical situations would affect low-status group members' performance more strongly than high-status group members'. Experiment 1 and 2 tested this hypothesis using gender as a proxy of chronic social status and a gender-neutral task thathas been randomly presented to favor boys (men superiority condition), favor girls (women superiority condition), or show no gender preference (control condition). Both experiments found that women's (Experiment 1) and girls' performance (Experiment 2) suffered more from the evoked stereotypes than did men's and boys' ones. This result was replicated in Experiment 3, indicating that short men (low-status group) were more affected compared to tallmen (high-status group). Additionally, men were more affected compared to women when they perceived height as a threat. Hence, individuals are more or less vulnerable to identity threats as a function of the chronic social status at play; enjoying a high status provides protection and endorsing a low one weakens individual performance in stereotypical situations.

PURPOSE OF REVIEW: Trimodal therapy (TMT) is considered the most effective bladder-sparing approach for muscle-invasive urothelial carcinoma of the bladder (MIBC) and an alternative to radical cystectomy. The purpose of this article was to review and summarize the current knowledge on the equivalence of TMT and radical cystectomy based on the recent literature. RECENT FINDINGS: TMT consists of a maximal transuretral resection of the bladder, followed by a concurrent radiotherapy and chemotherapy, limiting salvage radical cystectomy to nonresponder tumors or muscle-invasive recurrence. In large population studies, less than 6% of the patients with nonmetastatic MIBC receive a chemoradiation therapy and this rate is stable. A growing body of evidence exists that TMT provides good oncologic outcomes with low morbidity when compared with radical cystectomy. TMT requires, however, a close follow-up because of the high risk of local recurrence and salvage radical cystectomy in up to 30% of the patients. Salvage radical cystectomy can be performed with adequate results but does not offer the same opportunity of reconstruction and functional outcomes than primary radical cystectomy. SUMMARY: Although radical cystectomy is still the treatment of reference for most of the patients with localized MIBC, TMT represents a reasonable alternative in highly selected patients. Any firm conclusion on the equivalence or superiority of one treatment to the other is still limited by the lack of randomized controlled trials and the heterogeneity of the available literature. Future studies and multidisciplinary approach are mandatory to optimize the patient selection and regimen of TMT.
