Randomized Controlled Trial Multicenter Study Comparative Study
Subperiosteal vs Subdural Drain After Burr-Hole Drainage of Chronic Subdural Hematoma: A Randomized Clinical Trial (cSDH-Drain-Trial).
The use of a subdural drain (SDD) after burr-hole drainage of chronic subdural hematoma (cSDH) reduces recurrence at 6 mo. Subperiosteal drains (SPDs) are considered safer, since they are not positioned in direct contact to cortical structures, bridging veins, or hematoma membranes. ⋯ Although the noninferiority criteria were not met, SPD insertion led to lower recurrence rates, fewer surgical infections, and lower drain misplacement rates. These findings suggest that SPD may be warranted in routine clinical practice.

More than half of astronauts returning from long-duration missions on the International Space Station present with neuro-ocular structural and/or functional changes, including optic disc edema, optic nerve sheath distension, globe flattening, choroidal folds, or hyperopic shifts. This spaceflight-associated neuro-ocular syndrome (SANS) represents a major risk to future exploration class human spaceflight missions, including Mars missions. Although the exact pathophysiology of SANS is unknown, evidence thus far suggests that an increase in intracranial pressure (ICP) relative to the upright position on Earth, which is due to the loss of hydrostatic pressure gradients in space, may play a leading role. This review focuses on brain physiology in the spaceflight environment, specifically on how spaceflight may affect ICP and related indicators of cranial compliance, potential factors related to the development of SANS, and findings from spaceflight as well as ground-based spaceflight analog research studies.

Neurological surgery practice is based on the science of balancing probabilities. A variety of clinical guidance documents have influenced how we collectively practice our art since the early 20th century. The quality of the science within these guidelines varies widely, as does their utility in positively shaping our practice. ⋯ The guidelines development process identifies areas, issues, and strategies for which little medical evidence exists, as well as topics that need focused scientific investigation and future study. The production of evidence-based practice recommendations is a vital part of furthering our specialty. Guidelines development advances our science, augments the resident education process, and protects our practice from undue external influence.

Multicenter Study
Association of Surgical Overlap during Wound Closure with Patient Outcomes among Neurological Surgery Patients at a Large Academic Medical Center.
Several studies have explored the effect of overlapping surgery on patient outcomes, but impact of surgical overlap during wound closure has not been studied. ⋯ Surgical overlap during wound closure (STO) is associated with improved or at least noninferior patient outcomes, as it pertains to readmissions and wound revisions.

Recommendations on the management of brain arteriovenous malformations (bAVM) with respect to pregnancy are based upon conflicting literature. ⋯ There is no conclusive evidence of an increased risk of first hemorrhage during pregnancy from bAVM. Because advice to women with bAVM may influence the management of pregnancy or bAVM with significant consequences, we believe that a retrospective multicenter, case crossover study is urgently required.
