Spinal myxopapillary ependymomas (MPEs) are slowly growing ependymal gliomas with preferential manifestation in young adults. The aim of this study was to assess the outcome patients MPE treated surgery, radiotherapy (RT), and/or chemotherapy. medical records 183 (male: 59%) at MD Anderson Cancer Center and 11 institutions from Rare Network were retrospectively reviewed. Mean patient' age diagnosis 35.5 ± 15.8 years. Ninety-seven (53.0%) underwent surgery without RT, 86 (47.0%) RT. Median RT...

: Patient safety is an activity to mitigate preventable patient harm that may occur during the delivery of medical care. The European Board Anaesthesiology (EBA)/European Union Medical Specialists had previously published recommendations on minimal monitoring and postanaesthesia care, but with growing public professional interest it was decided produce a much more encompassing document. EBA Society (ESA) consensus what needs be done/achieved for improvement peri-operative safety. During...

Background An unplanned admission to the intensive care unit within 24 h of a procedure (UIA) is recommended clinical indicator in surgical patients. Often regarded as surrogate marker adverse events, it has potential direct measure patient safety. Its true validity for such use currently unknown. Methods The authors validated UIA an safety patients prospective cohort study 44,130 admitted their hospital. They assessed association with intraoperative incidents and near misses, increased...

Summary Intra‐operative awareness in paediatric patients has been little studied for many years because of the difficulties relying on children's testimony. Earlier questionnaires used to detect this complication were not adapted language and memory capacities. By using a qualitative method, semi‐structured in‐depth interview their cognitive abilities, we have now conducted prospective evaluation incidence risk factors intra‐operative children undergoing general anaesthesia.
