Review Meta Analysis
Duret brainstem hemorrhage following trans-tentorial descending brain herniation: a systematic review and meta-analysis.
Historically, the occurrence of hemorrhage in the brainstem after an episode of supratentorial intracranial hypertension was described by Henri Duret in 1878. Nevertheless, to date the eponym Duret brainstem hemorrhage (DBH) lacks systematic evidence regarding its epidemiology, pathophysiology, clinical and radiologic presentation, and outcome. ⋯ Unlike its historical description, DBH appears as a focal hematoma in the upper brainstem caused by the rupture of anteromedial basilar artery perforators after sudden downward displacement of the brainstem, regardless of its cause.

Review Meta Analysis
Comparison of one-level osteotomy and two-level osteotomy in thoracolumbar kyphotic deformity in ankylosing spondylitis: a systematic review and meta-analysis.
One- and two-level osteotomies have been used to treat thoracolumbar kyphosis in patients with ankylosing spondylitis (AS). However, the effectiveness and safety of the 2 methods have not been systematically compared, and few studies have reported on which method might be more suitable for treating AS. ⋯ Our findings have shown that one-level osteotomy is safer than two-level osteotomy. For AS patients with nonsevere kyphosis, one-level osteotomy will be sufficient for spinal sequence correction and maintenance of balance, and two-level osteotomy will not be needed. For AS patients with severe kyphosis, two-level osteotomy can be recommended for better orthopedic effects; however, a careful surgical technique is required.

Spinal Fusion Versus Repeat Discectomy For Recurrent Lumbar Disc Herniation: A Systematic Review and Meta-Analysis.
Recurrent lumbar disc herniation (RLDH) is one of the major causes of failure for primary surgery. Repeat discectomy (RD) and spinal fusion (SF) are 2 surgical options for RLDH. The objective of our study is to compare the effectiveness of SF compared with RD in the treatment of RLDH. ⋯ The pooled evidence suggests that fusion achieves better results than RD for RLDH. The results of this review should be further confirmed by future high-quality randomized controlled trials.

Review Meta Analysis
Comparison of infection rates following immediate and delayed cranioplasty for post-craniotomy surgical site infections - Results of a meta-analysis.
Postoperative surgical site infections (SSIs) in neurosurgery are rare. However, they pose a formidable challenge to the treating neurosurgeon and substantially worsen patient outcomes. These infections require prompt intervention in the form of débridement, including removal of craniotomy bone. ⋯ Our analysis revealed that the pooled proportion of treatment failure was 10.4% (95% confidence interval [CI] 5.9%-17.8%) when an immediate cranioplasty was done and 16.1% (95% CI 7.2%-32.1%) when delayed cranioplasty was done. The pooled proportion of treatment failure was 12% (95% CI 5.9%-22.9%) when the same bone was used for cranioplasty and was 8% (95% CI 3%-20%) when prosthetic material such as titanium was used for cranial vault reconstruction. Thus, the rate of treatment failure was less when an immediate single-stage cranioplasty was done compared with a delayed cranioplasty following SSIs.

Review Meta Analysis
Targeted Temperature Management in Pediatric Traumatic Brain Injury: A Systematic Review and Network Meta-Analysis.
The efficacy of targeted temperature management, including the appropriate length of time, in pediatric traumatic brain injury is inconclusive. We aimed to compare the efficacy of normothermia and therapeutic hypothermia administered for various durations. ⋯ No conclusive evidence was found on optimal temperature management for pediatric traumatic brain injury. A large randomized controlled trial that considers the temperature control enforcement duration is required.
