The consequences of ventricular entry during resection of high-grade gliomas (HGG) are uncertain and often not detectable clinically. ⋯ The association between ventricular entry during HGG resection and tumor dissemination, hydrocephalus, and decreased survival invites investigations to understand this link. Neurosurgeons and neuro-oncologists must be aware of the consequences of ventricular entry during surgery for HGG.

Timing of surgery and the importance of the size of disc prolapse in cauda equina syndrome (CES) remain controversial. ⋯ No significant correlation was demonstrated between the preoperative duration of urinary dysfunction, the size of disc herniation relative to size of spinal canal, and postoperative urinary function in a large consecutive series of patients with CES.

The Barrow Neurological Institute (BNI) scale is a novel quantitative scale measuring maximal subarachnoid hemorrhage (SAH) thickness to predict delayed cerebral ischemia (DCI). This scale could replace the Fisher score, which was traditionally used for DCI prediction. ⋯ This multicenter external validation analysis confirms that patients with a higher BNI grade show a significantly higher risk for DCI; high BNI grade was a predictor for unfavorable outcome at discharge and 1FU.

Deep Brain Stimulation for Parkinson Disease Does not Worsen or Improve Postural Instability: A Prospective Cohort Trial.
Falls and postural instability (PI) are major sources of morbidity in Parkinson disease (PD). Deep brain stimulation (DBS) is a major therapy for PD. The effects of DBS on PI and falls remain controversial. ⋯ This evidence is consistent with the hypothesis that DBS does not worsen PI when measured at 3 and 12 mo postoperatively.

Stereotactic radiosurgery (SRS) has become popular as a standard treatment for cavernous sinus (CS) meningiomas. ⋯ The literature is limited to level III evidence with respect to outcomes of SRS in patients with CS meningioma. Based on the observed results, SRS offers a favorable benefit to risk profile for patients with CS meningioma.
