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.

Clinical Trial
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.

Observational Study
Long-Term Effectiveness of Gross-Total Resection for Symptomatic Spinal Cord Cavernous Malformations.
Intramedullary spinal cord cavernous malformations (CMs) account for 5% of all CMs in the central nervous system and 5% to 12% of all spinal cord vascular lesions, yet their optimal management is controversial. ⋯ Gross total resection of symptomatic spinal cord CMs can prevent further neurological decline. Our experience suggests excellent long-term outcomes and minimal surgical morbidity following resection.
