Surgery for adult spinal deformity (ASD) improves quality of life, yet morbidity is high. Sepsis is a challenging postoperative complication that can result in death and drive inpatient resources. ⋯ In patients undergoing ASD surgery, male sex, diabetes, ascites, bleeding disorder, functional dependency, excessive weight loss and increased operative time independently predicted sepsis. This perioperative patient profile can be used for preoperative risk assessment, patient counseling, and postoperative management for patients undergoing ASD surgery.

Military conflict and neurosurgery date back to antiquity. Neurosurgery's development is intimately linked with Harvey Cushing's military experience. Previous papers highlighted unique opportunities and socioeconomic challenges facing military neurosurgeons. ⋯ Those still currently serving trended towards dissatisfaction (P = .08), and current military neurosurgeons were only 0.29 times as likely to recommend military service to another neurosurgeon as compared to those who were retired or separated (P < .024). Service as a military neurosurgeon is an overwhelmingly positive experience but opportunities exist for mechanisms to increase operative case load, reduce administrative responsibilities, and reduce military-civilian income disparity. Addressing these issues is important as current military neurosurgeons were more likely to be dissatisfied with their military experience and less likely to recommend military service to another neurosurgeon.

Novel Findings in Obstetric Brachial Plexus Palsy: A Study of Corpus Callosum Volumetry and Resting-State Functional Magnetic Resonance Imaging of Sensorimotor Network.
The response of the brain to obstetric brachial plexus palsy (OBPP) is not clearly understood. We propose that even a peripheral insult at the developmental stage may result in changes in the volume of white matter of the brain, which we studied using corpus callosum volumetry and resting-state functional magnetic resonance imaging (rsfMRI) of sensorimotor network. ⋯ OBPP occurs in an immature brain and causes central cortical changes. There is secondary corpus callosum atrophy which may be due to retrograde transneuronal degeneration. This in turn may result in disruption of interhemispheric coactivation and consequent reduction in activation of sensorimotor network even in the ipsilateral hemisphere.

Rapid advancement of medical and surgical therapies, coupled with the recent preoccupation with limiting healthcare costs, makes a collision of the 2 objectives imminent. This article explains the value of cost-effectiveness analysis (CEA) in reconciling the 2 competing goals, and provides a brief introduction to evidence-based CEA techniques. The historical role of CEA in determining whether new neurosurgical strategies provide value for cost is summarized briefly, as are the limitations of the technique. Finally, the unique ability of the neurosurgical community to provide input to the CEA process is emphasized, as are the potential risks of leaving these important decisions in the hands of others.

Vincristine is a commonly used chemotherapeutic agent that results in debilitating untreatable peripheral neuropathy. ⋯ Our data suggest that HIFU increases mechanical and thermal thresholds in VIN rodents. Whether HIFU can preclude the development of reduced thresholds in the VIN model warrants further study.
