Review Meta Analysis Comparative Study
Determining the difference in clinical and radiological outcomes between expandable and non-expandable titanium cages in the cervical fusion procedures: A Systematic Review and Meta-Analysis.
Expandable cages have been increasingly used in cervical and lumbar reconstructions; however, there is a paucity in the literature on how they compare with traditional nonexpandable cages in the cervical spine. We present a systematic review and meta-analysis, comparing the clinical and radiologic outcomes of expandable versus nonexpandable corpectomy cage use in the cervical spine. ⋯ The use of expandable cages may carry a modest improvement in radiologic outcomes compared with nonexpandable cages in the cervical spine; however, they may also lead to a higher rate of revisions based on our analyses.

Review Meta Analysis
Intraoperative magnetic resonance imaging for low- and high-grade gliomas: what is the evidence? A meta-analysis.
The benefit of intraoperative magnetic resonance imaging (iMRI) in gliomas remains unclear. We performed a meta-analysis of outcomes with iMRI-guided surgery in high-grade gliomas (HGGs) and low-grade gliomas (LGGs). ⋯ IMRI use improved GTR in gliomas, including LGGs. However, no PFS and OS benefit was shown in the meta-analysis.

Diagnosis, Management, and Current Treatment Options: A Cervical Spine Osteochondroma Meta-Analysis.
Osteochondroma is described as a capped benign bony neoplasm that forms on the outer surface of bone. These tumors affect nearly 6 million people per year. Although osteochondromas most often involve the appendicular skeleton, many involve the spine, with many cases located in the cervical spine. ⋯ Spinal osteochondromas can be classified into 2 types: multiple osteochondromas in the context of patients with multiple hereditary exostosis (MHE) and solitary osteochondroma or solitary exostosis (SE). Previous reviews have captured only some of the available literature on cervical osteochondromas and have generally focused on either SE or those associated with MHE. The purpose of our review was to provide an extensive review of all previously reported cervical osteochondromas and to compare osteochondroma characteristics, clinical presentation, and outcomes in the context of MHE and SE.

Transient cardiac dysfunction, or Takotsubo cardiomyopathy, is a well-known complication among patients presenting with neurologic insult, who are described as having takotsubo syndrome. This condition is commonly associated with aneurysmal subarachnoid hemorrhage but has also been described in patients after cerebral surgery or in those with ischemic stroke, seizure, and traumatic brain injury. Current evidence suggests that cardiac dysfunction in these patients is a result of increases in catecholamines that are induced by supraphysiologic levels of sympathetic activity. The cardiac injury is typically reversible and carries a good prognosis, but secondary complications may arise if the diagnosis is not recognized early.

Review Meta Analysis
Failures in Revascularization for Pediatric Moyamoya Disease and Syndrome: A Scoping Review.
Moyamoya disease (MMD) and moyamoya syndrome (MMS) are a rare cause of stroke commonly managed surgically. We conducted a scoping review to identify the current scope of the literature regarding factors associated with failure of revascularization surgery for MMD and MMS in pediatric patients and to catalyze future research. ⋯ The existing literature indicates that factors such as cause, degree of moyamoya vessels, and surgical approach may affect the likelihood of Matsushima grade C revascularization in pediatric patients with MMD and MMS. Future studies are necessary to definitively elucidate factors associated with failure of revascularization surgery for pediatric MMD.
