Early involvement and research in neurosurgery can increase chances for medical students to matriculate successfully into residency. This study reports the creation of a Neurological Surgery Interest Group (NSIG) at the University of Pittsburgh School of Medicine and shares its activities over 2 academic years. ⋯ An NSIG can be mutually beneficial to both medical students and an institution's neurosurgical department. This study's findings may be applied to numerous specialties and across various academic institutions.

Observational Study
Incidence of postoperative hematomas requiring surgical treatment in neurosurgery: a retrospective observational study.
We aimed to characterize the occurrence of postoperative hematoma (POH) after neurosurgery overall and according to procedure type and describe the prevalence of possible confounders. ⋯ POH after neurosurgery was rare in this series but was associated with poor outcome. Identification of risk factors of bleeding, and avoiding them, if possible, might decrease the incidence of POH.

Frailty, decreased physiologic reserve and increased vulnerability to stressors beyond what is expected for normal aging, is associated with increased risk of morbidity and mortality. The objective of this study was to develop a preoperative frailty index for patients undergoing surgery for primary spinal column tumors that predicts morbidity, mortality, and length of stay. ⋯ Compared with patients without frailty, patients with mild, moderate, and severe frailty had significantly increased odds of developing postoperative complications. Systematic evaluation of preoperative frailty should play a key role in decision making for patients undergoing surgery for primary spinal tumors.

Magnetoencephalography (MEG) and functional magnetic resonance imaging (fMRI) provide noninvasive localization of eloquent brain areas for presurgical planning. The aim of this study is the integration of MEG and fMRI maps into a CyberKnife (CK) system to optimize dose planning. ⋯ The availability of advanced neuroimaging techniques is playing an increasingly important role in radiosurgical planning strategy. We successfully imported MEG and fMRI activations into a CK system. This additional information can improve dose sparing of eloquent areas, allowing a more comprehensive investigation of the related dose-volume constraints that in theory could translate into a gain in tumor local control, and a reduction of neurological complications.

Posterior fossa decompression surgeries for Chiari malformations are susceptible to postoperative complications such as pseudomeningocele, external cerebrospinal fluid (CSF) leak, and meningitis. Various dural substitutes have been used to improve surgical outcomes. ⋯ Dural substitutes generated from porcine collagen, compared with those from bovine collagen, were associated with a higher likelihood of pseudomeningocele development in adult patients undergoing Chiari I malformation decompression and duraplasty.
