The Karnofsky Performance Scale (KPS) score is a widespread metric to stratify patient prognosis and determine appropriate management in glioblastoma multiforme(GBM). Low preoperative KPS values have been associated with shorter overall survival (OS). However, surgical resection can have a dramatic effect on a patient’s functional status which subsequently(More)
OBJECT Misrepresentation of scholarly achievements is a recognized phenomenon, well documented in numerous fields, yet the accuracy of reporting remains dependent on the honor principle. Therefore, honest self-reporting is of paramount importance to maintain scientific integrity in neurosurgery. The authors had observed a trend toward increasing numbers of(More)
Subarachnoid hemorrhage related to aneurysmal rupture (aSAH) carries significant morbidity and mortality, and its treatment is focused on preventing secondary injury. The most common-and devastating-complication is delayed cerebral ischemia resulting from vasospasm. In this paper, the authors review the various surveillance technologies available to detect(More)
Pituitary adenomas are common in the general population. They can be complicated by intratumoral hemorrhage, otherwise known as apoplexy, which frequently presents with neurologic deficits that may necessitate urgent surgical decompression. Many risk factors for pituitary apoplexy have been suggested in the literature. We present a case of symptomatic(More)
Objectives To determine the cost of annual magnetic resonance imaging (MRI) surveillance after resection of nonfunctioning pituitary adenomas (NFPAs) and its effectiveness in reducing visual compromise due to tumor recurrence. Design Retrospective case series. Setting Vanderbilt University Medical Center (2003-2011). Participants A total of 120 patients(More)
