The aim of this study was to characterize the payments made by medical industry to neurosurgeons from 2014 to 2018. ⋯ Our study shows that over the most recent 5-year period (2014-2018) of the Centers for Medicare and Medicaid Services Open Payments Database, there was a decreasing trend of the total number of payments, but an increasing trend of the total amount paid to neurosurgeons.

Observational Study
Automated Pupillometry as a Triage and Assessment Tool in Patients with Traumatic Brain Injury.
Traumatic brain injury (TBI) is a leading cause of morbidity and mortality in young adults. Automated infrared pupillometry (AIP) has shown promising results in predicting neural damage in aneurysmal subarachnoid hemorrhage and ischemic stroke. We aimed to explore potential uses of AIP in triaging patients with TBI. We hypothesized that a brain injury severe enough to require an intervention would show Neurologic Pupil Index (NPI) changes. ⋯ AIP could be useful in triaging comatose patients after blunt TBI. An NPI ≥3 may be reassuring in patients with no signs of mass effect or increased ICP.

Spinal cord injuries (SCIs) are difficult to treat. The first animal SCI model (featuring the dropping of a weight) was established by Allen in 1911, and other animal models have been developed since then. ⋯ No consensus on an optimal animal model for cerebral research has emerged. We discuss the appropriate SCI models for studying secondary brain changes.

Review Meta Analysis
The Effects of Surgery and Adjuvant Therapy on Survival Outcomes in Clear Cell Ependymomas: A Systematic Review and Meta-Analysis of Individual Patient Data.
The survival outcomes of clear cell ependymomas are poorly understood. This study clarifies the role of surgery and adjuvant therapy when this morphologically distinct tumor is encountered. ⋯ Clear cell ependymomas are particularly aggressive in those aged >50 years. Gross total resection remains the cornerstone of management. Postoperative adjuvant therapy is likely to be of survival benefit only after subtotal resection.

Meningiomas are mostly benign intradural tumors. Concerning the spine, some of them can extend outside the canal or even develop extradurally but their primary attach is often located in the vertebral canal. Here we present the case of an exceptional purely intraforaminal meningioma mimicking a neurogenic tumor, involving the vertebral artery and presenting with cervicobrachial neuralgia and slight motor deficit.
