To the Editor: Commercial stem-cell clinics have been highly publicized in the lay press and operate worldwide with limited or no regulation.1 We report the case of a 66-year-old man who underwent intrathecal infusions for the treatment of residual deficits from an ischemic stroke at commercial stem-cell clinics in China, Argentina, and Mexico. He was not(More)
OBJECT Although the length of hospital stay is often used as a measure of quality of care, data evaluating the predictors of extended hospital stay after craniotomy for tumor are limited. The goals of this study were to use multivariate regression to examine which preoperative characteristics and postoperative complications predict a prolonged hospital stay(More)
Methods for rapid and objective quantification of interictal spikes in raw, unprocessed electroencephalogram (EEG) samples are scarce. We evaluated the accuracy of a tailored automated spike quantification algorithm. The automated quantification was compared with the quantification by two board-certified clinical neurophysiologists (gold-standard) in five(More)
INTRODUCTION Although reoperation has been utilized as a metric of quality of care, no national analysis has evaluated the rate of, reasons for, and predictors of unplanned reoperation after craniotomy for tumor. METHODS Patients who underwent cranial tumor resection were extracted from the prospective National Surgical Quality Improvement Program (NSQIP)(More)
BACKGROUND In cases of severe traumatic brain injury, cerebrospinal fluid (CSF) diversion though an external ventricular drain (EVD) is a proven method to assist in the control of elevated intracranial pressure. Under normal circumstances, the EVD is placed in a frontal location. However, in cases of multifocal intracranial injury and swelling, collapse of(More)
OBJECTIVE Although there is a growing body of research highlighting the negative impact of obesity and malnutrition on surgical outcomes, few studies have evaluated these parameters in patients undergoing intracranial surgery. The goal of this study was to use a national registry to evaluate the association of body mass index (BMI) and hypoalbuminemia with(More)
Stereotactic radiosurgery is one of the treatment options for brain metastases. However, there are patients who will progress after radiosurgery. One of the potential treatments for this subset of patients is laser ablation. Image-guided stereotactic biopsy is important to determine the histopathological nature of the lesion. However, this is usually based(More)
INTRODUCTION Patients with aneurysmal subarachnoid hemorrhage (SAH) frequently undergo multiple angiographic studies within a 48-h period. We sought to evaluate the impact of these repeated contrast loads on renal function. METHODS We reviewed the records of a consecutive series of 104 patients with aneurysmal subarachnoid hemorrhage, most of whom(More)
