BACKGROUND The endoscopic endonasal approach for pituitary neoplasms has shown similar efficacy compared with the microscopic approach. However, outcomes and complication rates with larger macroadenomas is not as well documented. This study addresses the efficacy and outcome of the fully endoscopic endonasal approach for large and giant pituitary adenomas.(More)
Objective To establish a maximum tolerated dose of superselective intraarterial cerebral infusion (SIACI) of Cetuximab after osmotic disruption of the blood–brain barrier (BBB) with mannitol, and examine safety of the procedure in patients with recurrent malignant glioma. Methods A total of 15 patients with recurrent malignant glioma were included in the(More)
OBJECT The use of the Pipeline Embolization Device (PED) as a sole endovascular modality has been described for the treatment of brain aneurysms. The benefit of using coils concurrently with a limited number of PEDs is not well documented. The authors describe their experience with this technique as well as their midterm clinical and angiographic results.(More)
Most common reason for the vesicouterine fistula is a cesarean section; no cases were reported of degenerated uterine leiomyoma communicating with the urinary bladder. We report a case of fistulous communication between the degenerated leiomyoma and the bladder. The patient's initial clinical presentation was consistent with recurrent UTI. She underwent(More)
OBJECTIVE Endoscopic thoracic sympathectomy (ETS) remains the definitive treatment for primary focal hyperhidrosis. Compensatory hyperhidrosis (CH) is a significant drawback of ETS. We sought to identify the predictors for the development of severe CH after ETS, its anatomic locations, and its frequency of occurrence, and we analyzed the impact of CH on(More)
We discuss the requirement of basic quality of service (QoS) in optical burst switched WDM networks considering their delay and loss probability. Low delay and reducing burst overlap in the electronic domain of an ingress node reduces burst loss, and hence improves (QoS). A simplified mathematical model for delay versus traffic loads considering both low(More)
OBJECTIVE Conventional surgical treatment of bilateral ophthalmic aneurysms would require bilateral craniotomies and bilateral neck dissections for proximal control of the cervical internal carotid artery (ICA). We present a semiemergent case where bilateral ophthalmic artery aneurysms were clipped using a unilateral mini-pterional craniotomy and(More)
BACKGROUND Neurenteric cysts are rare congenital lesions along the neuroaxis, typically found in the spine, and rarely intracranially. Here, we present 3 patients who presented to our institution during a 6-year period with supratentorial intracranial neurenteric cysts and conduct a comprehensive review of the literature to describe the salient pathology,(More)
The goal of any neurosurgical procedure for tumor removal involves balancing the morbidity of the operation and necessity for total resection of the tumor. This calculation becomes especially complex in regard to chordomas—relatively slowgrowing tumors, which can have devastating effects if either untreated, or improperly resected. As tumors arising from(More)
