OBJECT Seizures occur in approximately 80% of patients with low-grade gliomas (LGGs). The majority of patients are treated with anticonvulsant monotherapy; however, many patients require multidrug therapy, or their seizures are refractory to antiepileptic drugs altogether. The oral alkylating agent temozolomide has emerged as a potential initial treatment(More)
The modified adhesive removal (sticky-tape) test is an assessment of somatosensory dysfunction following cerebral ischemia in rats. This test is less time consuming than the original protocol by virtue of requiring minimal pre-training. We present a detailed protocol describing how to conduct the modified adhesive removal (sticky-tape) test. Following right(More)
BACKGROUND Intracerebral hemorrhage (ICH) is associated with neurological injury that may be ameliorated by a neuroprotective strategy targeting the complement cascade. We investigated the role of C5a-receptor antagonist (C5aRA) solely and in combination with C3a-receptor antagonist (C3aRA) following ICH in mice. METHODS Adult male C57BL/6J mice were(More)
We wanted to determine the neurocognitive profile of adult patients with moyamoya disease prior to neurosurgical intervention. The experience of three United States medical centers, Columbia University, University of Illinois at Chicago, and the University of Texas Southwestern Medical Center at Dallas, were combined. Clinical data from adult patients (N =(More)
OBJECT Pituitary adenomas are fairly common intracranial neoplasms, and nonfunctioning ones constitute a large subgroup of these adenomas. Complete resection is often difficult and may pose undue risk to neurological and endocrine function. Stereotactic radiosurgery has come to play an important role in the management of patients with nonfunctioning(More)
OBJECT Flow diverters are increasingly used for treatment of intracranial aneurysms. In most series, the Pipeline Embolization Device (PED) was used for the treatment of large, giant, complex, and fusiform aneurysms. Little is known about the use of the PED in small aneurysms. The purpose of this study was to assess the safety and efficacy of the PED in(More)
The goal of cerebral arteriovenous malformation (AVM) treatment is to eliminate intracerebral hemorrhage risk and to preserve or maximize neurological functions of the patient. Interventional planning must determine the modality or combination of modalities with the greatest success rate according to patient characteristics, AVM architecture, and the(More)
Moyamoya disease is a chronic cerebrovascular occlusive disorder that results in severe morbidity and death. There is much controversy surrounding the optimal treatment for adult patients with the disorder. There have been no randomized trials to assess the efficacy of any single surgical treatment, and existing case series suffer from inadequate power,(More)
BACKGROUND Endovascular therapy is now the preferred treatment option for basilar tip aneurysms (BTAs). OBJECTIVE To compare the safety and efficacy of common endovascular techniques in the treatment of BTAs. METHODS A retrospective review was conducted of 235 patients with BTAs treated with endovascular means in our institution between 2004 and 2011.(More)
BACKGROUND Neuroblastoma is a childhood cancer with considerable morbidity and mortality. Tumor-derived biomarkers may improve risk stratification. METHODS We screened 915 samples of neuroblastoma for loss of heterozygosity (LOH) at chromosome bands 1p36 and 11q23. Additional analyses identified a subgroup of cases of 11q23 LOH with unbalanced 11q LOH(More)
