Evaluation of cost and survival in intracranial gliomas using the Value Driven Outcomes database: a retrospective cohort analysis.
Gliomas occur in 3-4 individuals per 100,000 individuals and are one of the most common primary brain tumors. Treatment options are limited for gliomas despite the progressive nature of the disease. The authors used the Value Driven Outcomes (VDO) database to identify cost drivers and subgroups that are involved in the surgical treatment of gliomas. ⋯ Understanding care costs is challenging because of the highly complex, fragmented, and variable nature of healthcare delivery. Adopting effective strategies that would reduce facility costs and limit LOS is likely the most important aspect in reducing intracranial glioma treatment costs.

Optic nerve sheath diameter ultrasonography at admission as a predictor of intracranial hypertension in traumatic brain injured patients: a prospective observational study.
Intracranial hypertension and impaired cerebral autoregulation are common causes of secondary injuries in patients with traumatic brain injury (TBI). The primary outcome of this study was to assess whether a noninvasive method to estimate intracranial pressure (ICP) based on the ultrasonography of the optic nerve sheath diameter (ONSD) measured at the time of neurocritical care unit (NCCU) admission is correlated with the mean ICP during NCCU stay. Secondary outcomes were to assess whether ONSD is correlated with the dose of ICP > 20 mm Hg and impaired autoregulation during NCCU stay and with instantaneous ICP and whether ONSD is associated with NCCU mortality. ⋯ ONSD measured at NCCU admission can give important information about patients at risk of developing intracranial hypertension and impaired autoregulation. ONSD examination could be useful to screen patients at admission to determine who would benefit from further invasive ICP monitoring.

Hemorrhage risk of cerebral dural arteriovenous fistulas following Gamma Knife radiosurgery in a multicenter international consortium.
The authors performed a study to evaluate the hemorrhagic rates of cerebral dural arteriovenous fistulas (dAVFs) and the risk factors of hemorrhage following Gamma Knife radiosurgery (GKRS). ⋯ Patients have similar rates of hemorrhage before and after radiosurgery until obliteration is achieved. dAVFs that have any CVD or are located in the convexity or torcula were more likely to present with hemorrhage. Patients presenting with nonhemorrhagic neural deficits and a history of endovascular treatments had higher risks of post-GKRS hemorrhage.

Global neurosurgery: continued momentum at the 72nd World Health Assembly.
Global neurosurgery is the practice of neurosurgery with the primary purpose of delivering timely, safe, and affordable neurosurgical care to all who need it. This field is led by neurosurgeons, and global neurosurgery sessions are now part of every major international neurosurgical meeting. The World Federation of Neurosurgical Societies (WFNS) is working to coordinate activities and align all related activities for greater impact. ⋯ Participation by neurosurgeons continues to grow as many WHA events focused on global surgery have intrinsically involved neurosurgical leadership and participation. This year, resolution WHA72.31, entitled "Emergency and trauma care, Emergency care systems for universal health coverage: ensuring timely care for the acutely ill and injured," was passed. This resolution provides further opportunities for neurosurgical advocacy as the landscape of global surgery gains recognition and momentum.

Retrosigmoid approach for glycerin rhizotomy in the treatment of trigeminal neuralgia without overt arterial compression: updated case series.
Trigeminal neuralgia (TN) is a neuropathic pain disorder characterized by severe, lancinating facial pain that is commonly treated with neuropathic medication, percutaneous rhizotomy, and/or microvascular decompression (MVD). Patients who are not found to have distinct arterial compression during MVD present a management challenge. In 2013, the authors reported on a small case series of such patients in whom glycerin was injected intraoperatively into the cisternal segment of the trigeminal nerve. The objective of the authors' present study was to report their updated experience with this technique to further validate this novel approach. ⋯ Intraoperative injection of glycerin into the trigeminal nerve is a generally safe and potentially effective treatment for TN when no distinct site of arterial compression is identified during surgery or when decompression of the nerve is deemed to be inadequate.
