Review Meta Analysis
Systemic review and meta-analysis of the intellectual integrity of children with Neurofibromatosis type 1 (NF-1).
Cognitive impairment is a common neurologic complication of neurofibromatosis type 1 (NF-1) in childhood. A great number of learning disabilities appear in 30%-65% of children with NF-1. The aim of the study is to compare intelligence quotient (IQ) scores between children with NF-1 and comparable control groups. ⋯ The current meta-analysis illustrated a significant intellectual deficit in children with NF-1 compared with their typically developed peers who were matched by age. Performance IQ was significantly impaired compared with verbal IQ in NF-1 children. The current findings may guide experts to tailor individualized educational programs for children with NF-1.

Meningioma consistency is one of the most critical factors affecting the difficulty of surgery. Although many studies have attempted to predict meningioma consistency via magnetic resonance imaging findings, no definitive method has been established, because most have been based on qualitative evaluations. Therefore, the present study examined the potential of the T2 relaxation time (T2 value), a tissue-specific quantitative parameter, for assessment of meningioma consistency. ⋯ The T2 values could be a reliable quantitative predictor of meningioma consistency, and the T2 value distribution map, which elucidated the internal structure of the tumor in detail, could provide helpful information for surgical resection.

Racial Disparities in Outcomes After Spine Surgery: A Systematic Review and Meta-Analysis.
Racial disparities are a major issue in health care but the overall extent of the issue in spinal surgery outcomes is unclear. We conducted a systematic review/meta-analysis of disparities in outcomes among patients belonging to different racial groups who had undergone surgery for degenerative spine disease. ⋯ Black patients have a significantly higher risk of unfavorable outcomes after spine surgery compared with white patients. Further work in understanding the reasons for these disparities will help develop strategies to narrow the gap among the racial groups.

Meta Analysis
Natural history of brainstem cavernous malformations: on the variation in hemorrhage rates.
Hemorrhage rates of conservatively managed brainstem cavernous malformations (BSCMs) vary widely in the literature. We aimed to elucidate the reason for the variation and to add the results of our experience of BSCMs management over the past decade. ⋯ The reported hemorrhage rates are calculated in 2 different ways. In our patient cohort, both the retrospective and prospective hemorrhage rates were in accordance with those in the literature. The long-term hemorrhage rate lies between the prospective and retrospective rate.

Multicenter Study Comparative Study
Chronic subdural hematoma drainage under local anesthesia with sedation versus general anesthesia and its outcome.
Burr hole drainage is the criterion standard treatment for chronic subdural hematoma (CSDH), a common neurosurgical condition. However, apart from the surgical technique, the method of anesthesia also has a significant impact on postoperative patient outcome. Currently, there are limited studies comparing the use of local anesthesia with sedation (LA sedation) versus general anesthesia (GA) in the drainage of CSDH. The objective of this study was to compare the morbidity and mortality outcomes of using LA sedation versus GA in CSDH burr hole drainage. ⋯ This study demonstrates that CSDH drainage under LA sedation is safe and efficacious, with a significantly lower risk of postoperative mortality and morbidity when compared with GA.
