Endoscopic third ventriculostomy (ETV) is currently the principal alternative to cerebrospinal fluid shunt placement in the management of pediatric hydrocephalus. Cost-effectiveness analysis can help determine the optimal strategy for integrating these different approaches. ⋯ In this matched cohort, ETV was not significantly less costly or more effective over a median 35 months of follow-up, with a 54% initial ETV success rate, even before the additional morbidity and mortality encountered were taken into account. The time course for the accrued costs suggests that a larger cohort, longer follow-up, or higher success rates are needed to demonstrate the cost-effectiveness of this therapy.

This study was performed to evaluate the clinical manifestations and prognostic factors for outcomes among patients with nontuberculous spinal epidural abscesses. ⋯ Surgical decompression combined with antimicrobial therapy remains the recommended treatment. In addition to abscess locations and motor deficits, inflammatory markers such as WBC counts and C-reactive protein levels are prognostic for outcomes.

Posttraumatic temperature manipulations have been reported to significantly influence the inflammatory response to traumatic brain injury (TBI). The purpose of this study was to determine the temporal and regional profiles of messenger ribonucleic acid (mRNA) expression and protein levels for the proinflammatory cytokine interleukin-1beta (IL-1beta), after moderate or severe TBI. The effects of posttraumatic hypothermia (33 degrees C) or hyperthermia (39.5 degrees C) on these consequences of TBI were then determined. ⋯ Injury severity determines the degree of IL-1beta protein level elevation after TBI. The effects of posttraumatic hypothermia on IL-1beta protein levels (an important mediator of neurodegeneration after TBI) may partly explain the established effects of posttraumatic temperature manipulations on inflammatory processes after TBI.
