Meningiomas are a common primary central nervous system tumor that lack a U.S. Food and Drug Administration-approved pharmacotherapy. Approximately 20%-35% of meningiomas are classified as higher grade with poor outcome, whereas patients with lower-grade meningiomas are known to have long-term neurologic deficits and reduced overall survival. Recent efforts to understand the epigenetic landscape of meningiomas have highlighted the importance of DNA methylation for predicting tumor outcomes and prognosis; therefore, inhibition of these pathways may present a viable therapy for these tumors. ⋯ Our work has identified a potential drug candidate in decitabine for the treatment of meningiomas regardless of clinical subgroup. These data require further evaluation in preclinical models, and the conclusions based on clinical subgroups need to be evaluated in a larger cohort to achieve appropriate statistical power.

Technological advancement in neurosurgery is a continuous process aimed at improving existing devices and implementing innovative ones. Recently, artificial intelligence (AI)-derived technologies (i.e., machine learning and virtual or augmented reality) have been entering this field, promising to significantly change its future. The acquisition of technological skills should be a goal of training for young neurosurgeons. The aim of this study is the analysis of competence and attitude toward intraoperative devices of young neurosurgeons. ⋯ Italian young neurosurgeons have acquired technical skills sufficient for the autonomous use of the most common operative devices, reporting a positive attitude toward technology with high motivation to learn and awareness of their potential harmfulness. A promising number of participants had already used AI-derived technologies, although only a few had received focused training for these devices.

Given the paucity of relevant data, the Council of State Neurosurgical Societies Workforce Committee launched a survey of neurosurgeons to assess patterns in activity restriction recommendations following spine surgery; the ultimate goal was to optimize and potentially standardize these recommendations. The aim of this initial study was to determine current practices in activity restrictions and return to work guidelines following common spinal procedures. ⋯ This survey demonstrated little consistency regarding return to work recommendations, general activity restrictions, and orthosis utilization following common spinal surgical procedures. Addressing this issue also has significant implications for the societal and personal costs of spine surgery.

The ClearPoint SmartFrame Array (ClearPoint Neuro, Inc., Solana Beach, CA) system consists of a magnetic resonance imaging compatible frame supported by a customized neuro navigation software. This system received U.S. Food and Drug Administrationclearance for clinical use in January 2021. Our objective was to report initial safety data and user experience of SmartFrame Array-supported stereotactic procedures. ⋯ The SmartFrame Array system offers a more rigid and compact build to enhance procedural efficiency while maintaining accuracy and safety. The design supports multi-trajectory stereotaxis, allowing novel clinical applications.

The transorbital endoscopic approach has been increasingly employed in the management of skull base disease.1-4 We present a case of a 48-year-old woman with a 2-month history of progressively worsening headache referred to our neurosurgery division after a new-onset generalized seizure. On examination, she was found to have diminished olfaction with no additional findings, including no visual or cognitive deficits. Preoperative imaging revealed a large anterior fossa mass originating at the left olfactory groove with leftward extension and prominent anterior and posterior ethmoidal arterial feeders. ⋯ Postoperative imaging confirmed gross total tumor resection without evidence of recurrence. This case highlights the application of the transorbital endoscopic approach in the management of anterior cranial base tumors. Advantages of this approach include minimal invasive access, avoidance of brain retraction, and ease for early tumor devascularization.
