The Nationwide Inpatient Sample Subarachnoid Hemorrhage (SAH) Severity Score (NIS-SSS) was developed as a measure of SAH severity for use in administrative databases. The NIS-SSS consists of International Classification of Diseases Ninth Revision (ICD-9) diagnostic and procedure codes derived from the SAH inpatient course and has been validated against the Hunt-Hess score (HH). ⋯ The NIS-SSS and m-NIS-SSS have good external validity, and therefore, may be suitable to approximate traditional clinical scores of disease severity in SAH research using administrative data.

Spinal cord stimulation (SCS) is an effective treatment in chronic neuropathic pain, but its efficacy in complex regional pain syndrome (CRPS) needs to be proven. ⋯ Despite the fact that CRPS patients were not able to discontinue or reduce their strong opioid or neuropathic pain medication use, 70% continued to use their SCS device during a median 8-yr follow-up.

Historical Article
First Female Neurosurgeon in the United States: Dorothy Klenke Nash, MD.
Dr Dorothy Klenke Nash (1898-1976) became the first female neurosurgeon in the United States in 1928 and maintained her status as the country's only female neurosurgeon until 1960. She graduated with her medical degree from the Columbia College of Physicians and Surgeons in 1927 and then trained at the Neurologic Institute of New York under Dr Byron Stookey. During her training, she contributed to the advancement of neurosurgical practice through academic research. ⋯ She retired from neurosurgical practice in 1965, at which time she devoted herself to her grandchildren and her Catholic faith. She died on March 5, 1976 at the age of 77. With unwavering tenacity, Dr Nash paved the way for all women in neurosurgery.

During focused ultrasound ablation (FUSA), the presumed stereotactic target is tested with subthreshold sonications before permanent ablation. This testing relies on ultrasound-induced reversible clinical effects (thermal neuromodulation, TN). However, the thermal dose and spot size thresholds to induce TN are not yet defined. ⋯ The TN thermal dose and spot size thresholds are significantly higher than the current FUSA standard of care. We recommend long duration (>30 s), subthreshold sonications for intraoperative testing during FUSA. Future investigations should test whether the thermal dose threshold is tissue-specific and determine the mechanisms underlying focused ultrasound TN.

Surgery of Insular Diffuse Gliomas-Part 1: Transcortical Awake Resection Is Safe and Independently Improves Overall Survival.
Insular diffuse glioma resection is at risk of vascular injury and of postoperative new neurocognitive deficits. ⋯ Awake surgery preserving the brain connectivity is safe, allows larger resections for insular diffuse gliomas than asleep resection, and positively impacts overall survival.
