The standard treatment of hydrocephalus is placement of a ventriculoperitoneal (VP) shunt. While infection is a common complication, rarely are fungal organisms implicated. Cryptococcus neoformans has been reported in only nine cases of shunt infection to our knowledge. The timing from shunt placement to symptom onset varies widely from 10 days to 15(More)
STUDY DESIGN Retrospective database review of a prospectively maintained neurosurgical database. OBJECTIVE The surgical management of cervical spinal epidural abscesses (CSEA) is reviewed examining the shift from single to staged anteroposterior decompression and stabilization. SUMMARY OF BACKGROUND DATA CSEA management is guided by small case series.(More)
The Escobar variant of multiple pterygium syndrome (OMIM #265000) is a rare, autosomal recessive disorder associated with mutations in the γ-subunit of the nicotinic acetylcholine receptor (CHRNG). CHRNG is expressed in fetal muscle during motor development and contributes to the formation of neuromuscular junctions (NMJs). Anomalies in NMJ structure and(More)
OBJECT One often overlooked aspect of spinal epidural abscesses (SEAs) is the timing of surgical management. Limited evidence is available correlating earlier intervention with outcomes. Spinal epidural abscesses, once a rare diagnosis carrying a poor prognosis, are steadily becoming more common, with one recent inpatient meta-analysis citing an approximate(More)
INTRODUCTION This article reviews the literature regarding tandem asymptomatic cervical stenosis in the setting of symptomatic lumbar stenosis. The presenting features of cervical spondylotic myelopathy are insidious and consistent with upper motor neuron loss. Often, asymptomatic cervical stenosis is encountered in the clinical setting during the workup of(More)
OBJECTIVE Resection significantly improves the clinical symptoms and functional outcomes of patients with intradural extramedullary tumors. However, patient quality of life following resection has not been adequately investigated. The aim in this retrospective analysis of prospectively collected quality of life outcomes is to analyze the efficacy of(More)
STUDY DESIGN Open-label laboratory investigational study; non-animal surgical simulation. OBJECTIVE The authors perform a comparison of dural closure strength in a durotomy simulator across 2 different suture materials. SUMMARY OF BACKGROUND DATA Incidental durotomy leading to persistent cerebrospinal fluid leak adds considerable morbidity to spinal(More)
Syringomyelia is a potentially debilitating disease that involves abnormal CSF flow mechanics; its incidence after traumatic spinal cord injury (SCI) is approximately 15%. Treatment consists of restoration of CSF flow, typically via arachnoidolysis and syrinx decompression. The authors present a case of pronounced syringomyelia in a patient with concomitant(More)
