Meta Analysis
A meta-analysis on the clinical significance of redundant nerve roots in symptomatic lumbar spinal stenosis.
Symptomatic lumbar spinal stenosis (LSS), which leads to severe socioeconomic consequences and places a heavy burden on global healthcare system, is a relatively frequent spine disorder. Redundant nerve roots (RNRs) are a relatively common finding in which slender, serpiginous, or tortuous nerve roots are found in the subarachnoid space of the lumbar spine. Previous studies that evaluated the prognostic assessment of RNRs in patients with symptomatic LSS are composed of doubtful results. Therefore, the clinical significance of RNRs in symptomatic LSS is still uncertain. The aim of this meta-analysis is a systematic assessment of the clinical significance of RNR syndrome in symptomatic LSS. ⋯ RNR is an entity in association with symptomatic LSS, which may be viewed as a potentially powerful prognostic indicator of worse postoperative functional recovery for symptomatic LSS.

Percutaneous dilatational tracheostomy (PDT) is a commonly performed method in neurocritical care, and its safety has been proven in numerous studies. Nevertheless, data regarding the application in patients with acute brain injury and poor respiratory function are poor. The purpose of this study was to evaluate the incidence of hypoxemia and hypercapnia during PDT in those patients. ⋯ Regarding the intraoperative gas exchange, indication of PDT in patients with ABI and ARDS should be considered carefully. However, PDT in ABI patients with reduced PaO2/FiO2 ratio alone appears to be a safe procedure.

An important component of the residency application for neurosurgery is research experience and the subsequent number of produced publications. Bibliometrics research has been developed to establish quantitative methods for the standardization of publishing impactful research. This study aims to quantify the research productivity of medical students who successfully matriculated into a Neurosurgery residency program. ⋯ H-index is a powerful research predictor of matching into neurosurgical research institutions and can be improved by starting research early, targeting high impact journals, and participating in original clinical and laboratory investigations.

Review Case Reports
Spontaneous regression of a hypoglossal neurinoma: a case report and review of the literature.
Hypoglossal neurinomas are very rare intracranial tumors. The management choices include surgery, as the gold standard, and radiosurgery or a combination of both. Little is known about this condition and the behavior of this tumor. ⋯ Our case highlights the importance of considering careful observation and diligent follow-up as a treatment option, as these lesions can show spontaneous regression with no invasive approaches.
