Trends in medical device company payments in neurosurgery: a nationwide, multidatabase, geospatial analysis.
Industry partnerships help advance the field of neurosurgery. Given the nature of the field and its close relationship with innovation, neurosurgeons frequently partner with the medical device industry to advance technology and improve outcomes. However, this can create important ethical concerns for patients. In this paper, the authors sought to comprehensively study how physician payments from medical device companies have changed and what geographic parameters influence the trends observed over the years. ⋯ This analysis demonstrates that there are national hot spots and cold spots of physician payments, and offers some social, economic, and company-dependent predictors that may influence the magnitude of payments. Further analysis is needed to better understand this clinical-commercial partnership in healthcare, specifically within neurosurgical practice.

Association of persistent postoperative hyperglycemia with mortality after elective craniotomy.
The influence of persistent postoperative hyperglycemia after craniotomy has not yet been explored. This study aimed to investigate the hypothesis that persistent postoperative hyperglycemia is associated with mortality in patients undergoing an elective craniotomy. ⋯ In patients undergoing an elective craniotomy, moderate and severe persistent postoperative hyperglycemia were associated with an increased risk of mortality compared with normoglycemia, regardless of preoperative hyperglycemia.

The longitudinal risk of hemorrhage of melanoma brain metastases after Gamma Knife radiosurgery.
The objective of this study was to analyze the hemorrhagic risk of melanoma brain metastases after Gamma Knife radiosurgery (GKRS). ⋯ The definite hemorrhage risk of melanoma brain metastases after GKRS was 17% in the first 3 years and 95% of the lesional hemorrhage occurred within the 1st year. Surgical intervention was needed in 5% of patients. Antiplatelet agents and immune checkpoint inhibitors were associated with improved OS, while definite/possible hemorrhage was associated with worse OS.

The influence of prior percutaneous rhizotomy on outcomes following microvascular decompression for trigeminal neuralgia.
Microvascular decompression (MVD) is an effective intervention in patients with trigeminal neuralgia (TN). How prior rhizotomy can impact long-term pain outcomes following MVD is not well understood. In this study, the authors sought to compare pain outcomes in patients who had undergone primary MVD versus those who had undergone secondary MVD after a single or multiple rhizotomies. ⋯ Percutaneous rhizotomy does not complicate outcomes following subsequent MVD for TN pain. However, patients undergoing rhizotomy before MVD may have an increased risk of postoperative facial numbness compared to that in patients undergoing primary MVD.

Sanford Larson, MD, PhD: a pioneering neurosurgeon, scientist, and educator.
Dr. Sanford Larson, MD, PhD (1929-2012), was an influential figure in spinal neurosurgery. Dr. ⋯ His mentorship produced numerous leaders in organized neurosurgery and neurosurgical education, including Edward Benzel, MD, Dennis Maiman, MD, PhD, Joseph Cheng, MD, Shekar Kurpad, MD, PhD, and Christopher Wolfla, MD. Dr. Larson was a prominent leader in spinal neurosurgery and his legacy carries on today through his contributions to research, education, and surgical technique.
