Observational Study
Non-English Primary Language Is Associated with Short-Term Outcomes after Supratentorial Tumor Resection.
Despite research indicating that patients with non-English primary language (NEPL) have increased hospital length of stay (LOS) for craniotomies, there is a paucity of neurosurgical research examining the impact of language on short-term outcomes. This study sought to evaluate short-term outcomes for patients with English primary language (EPL) and NEPL admitted for resection of a supratentorial tumor. ⋯ Patients with NEPL have different short-term outcomes after supratentorial tumor resection that varies based on primary language. More research is needed to understand the mechanisms driving these findings and to clarify unique experiences for different populations with NEPL.

Occlusion of ventriculoperitoneal shunts placed after intraventricular hemorrhage occurs frequently. The objective of this study was to develop a hemorrhagic hydrocephalus model to assess the ability of an oscillating microactuator within the ventricular catheter (VC) to prevent shunt obstruction. ⋯ In addition to protecting the VC, the microactuator appeared to prevent hematoma obstructing the valve or distal catheter, resulting in a much longer duration of low intraventricular pressures. A microactuator activated by placing the patient's head in an external magnetic field could reduce shunt obstructions in hemorrhagic hydrocephalus.

Cortical spreading depolarization (CSD), cortical spreading ischemia (CSI), and early brain injury are involved in the occurrence of delayed brain ischemia after subarachnoid hemorrhage (SAH). We tested whether local application of magnesium (Mg) sulfate solution suppressed CSD and CSI, and decreased brain damage in a rat SAH-mimicking model. ⋯ Local application of Mg suppressed CSI and reduced brain damage in a rat SAH-mimicking model. Mg irrigation therapy may be beneficial to suppress brain damage due to CSI after SAH.

Case Reports
Minimally invasive contralateral over the top approach for lumbar calcified foraminal lesions: a technical note.
Various surgical techniques have been described to address intraforaminal/extraforaminal lumbar lesions. They vary from the classic posterior open approaches to minimally invasive techniques with tubular retractors and even endoscopy. These lesions have been approached from either an ipsilateral or a contralateral approach. Only a few reports have described a contralateral minimally invasive tubular approach to address these lesions. However, none of them have been able to address calcified pathologies. ⋯ To our knowledge, this is the first report of the expanded use of fixed tubular retractors to address calcified lumbar intraforaminal disc herniations. This approach allows a satisfactory access and view of the contralateral foramen and offending lesion. It permits a wide decompression while preserving the facet joint and thus prevents iatrogenic instability. It can also avoid the iliac crest, which does not allow an ipsilateral extraforaminal approach at the L5-S1 level. This approach is a safe and effective way to treat this specific pathology.

Juvenile nasopharyngeal angiofibromas (JNAs) are highly vascularized benign lesions that mainly arise in adolescent male patients. Current treatment options include observation, radiotherapy, or surgical resection. Surgical resection is the treatment of choice as it achieves immediate and complete results, thereby minimizing the risk of recurrence. ⋯ The sinonasal cavity was widely patent and no tumor recurrence was noted 5 months postoperatively. JNAs can be challenging to treat as they can invade extensively into local structures. A careful consideration of treatment options and approaches are necessary when faced with these lesions.
