Hospital and surgeon (provider) volume are associated with clinically significant outcomes for many types of surgery. Volume-outcome studies in patients undergoing radical cystectomy for bladder cancer have focused primarily on postoperative mortality. In the current study, the authors assessed the effect of cystectomy provider volume on long-term mortality. ⋯ High-volume providers were associated with improved long-term mortality rates compared with low-volume providers. This finding was independent of the effect of volume on perioperative mortality, suggesting that provider volume effects continue to manifest long after surgery.

Association of perioperative troponin and atrial fibrillation after coronary artery bypass grafting.
Prediction of atrial fibrillation (AF) after coronary artery bypass grafting (CABG) may lead to preventive or early treatment and improved outcome. We investigated the association of serial perioperative cardiac troponin T (cTNT) measurements with postoperative AF in patients undergoing CABG. ⋯ Perioperative cTNT is univariably associated with postoperative AF after CABG, but not independently. Further, no clinically useful cut-off point for preventive or early treatment could be identified. Both perioperative cTNT and postoperative AF are associated with negative outcome and prolonged hospital stay.

To evaluate EEG predictors of outcome in patients with altered sensorium suspected to have seizure and to assess whether short term EEG is as effective as long term continuous EEG (cEEG) in predicting the outcome of patients with altered sensorium due to neurological causes. ⋯ cEEG monitoring provides independent prognostic information in patients with altered sensorium and suspected seizures. Unfavorable findings include nonconvulsive seizures, periodic epileptiform discharges and abnormal background. Short term EEG is ineffective in detecting seizures on EEG in patients with altered sensorium and should not be used as substitute for Long term EEG.

Brainstem cavernous malformation (CM) poses a challenge to neurosurgeons in terms of operability, postoperative complications and unpredictable outcomes. The present study was conducted to analyze the clinical parameters that might predict the outcomes and to summarize our center experience in treatment of brainstem CM. ⋯ Favorable surgical outcomes can be predicted in brainstem CM patients with early age at presentation, pontine location of the cavernoma, favorable preoperative mRS and those undergoing early surgery. The outcomes at long-term follow-up were associated with location of the CM in the brainstem, size of the CM and the preoperative mRS.

Management and outcome of primary spinal ependymomas: a single center experience from Taiwan.
Surgical treatment of spinal ependymomas requires careful consideration of the relative risks of neurological worsening from surgery. Our aim was to determine the risk factors of neurological deterioration after surgery for spinal ependymomas. ⋯ The risk associated with surgical resection of spinal ependymomas should not be overlooked because of the significant incidence of neurological deterioration. The male gender and long-standing symptom (≥24 months) are risk factors of postoperative neurological worsening. Early diagnosis and surgery are therefore critical for successful treatment of spinal ependymomas.
