Review Meta Analysis
Cerebral Hyperperfusion Syndrome after Revascularization Surgery in Patients with Moyamoya Disease: Systematic Review and Meta-analysis.
Cerebral hyperperfusion syndrome (CHS) after bypass surgery is known as a complication of moyamoya disease (MMD). However, the incidence of CHS has not been accurately reported, and there is no consensus on related risk factors. ⋯ CHS is a common complication after revascularization surgery in MMD. It is more frequently seen in adult patients. The most common CHS-related symptom was TNDs, followed by hemorrhage and seizure.

The aim of the present study was to review the reported data for neurosurgical complication definitions, report the current scales used to classify these complications, and discuss their limitations. ⋯ No current standardized neurosurgical complication grade has been used throughout morbidity and mortality conferences. Although scales have been proposed in reported studies, each with their strengths and limitations, none of these has considered surgery complexity or patient frailty and comorbidities. We believe a comprehensive scale is required that includes a preoperative grading system that factors in baseline surgical complexity and patient frailty.

Review Case Reports
Stenting of mobile calcified emboli after failed thrombectomy in acute ischemic stroke: case report and literature review.
Mobile calcified emboli are a rare cause of large vessel occlusion and acute ischemic stroke and pose unique challenges to standard mechanical thrombectomy techniques. Intracranial stenting has been reported as a rescue maneuver in cases of failed mechanical thrombectomy owing to dissection or calcified atherosclerotic plaques, but its use for calcified emboli is not well described. ⋯ Mobile calcified emboli are rare causes of acute ischemic stroke. Intracranial stenting can be used to successfully treat calcified emboli when mechanical thrombectomy has failed.

Comparative Study
Comparison of Subthalamic Nucleus and Globus Pallidus Internus Deep Brain Stimulation Surgery on Parkinson's Disease-related Pain.
To analyze and compare the effects of subthalamic nucleus (STN) deep brain stimulation (DBS) and globus pallidus internus (GPi)-DBS on Parkinson disease (PD)-related pain. ⋯ Both GPi-DBS and STN-DBS were effective for analyzing PD-related pain and seemed to have similar efficacy. This study provides an important first-step toward determining different DBS targets for controlling PD-related pain. Follow-up prospective research is an appropriate next step on the path to multicenter clinical trials.

Review Case Reports
Epstein-Barr Virus-Associated Smooth Muscle Tumor of the Spine after Bone Marrow Transplant - a case report and review of literature.
Epstein-Barr virus-associated smooth muscle tumors (SMTs) are rare neoplasms that have been found to develop in immunocompromised patients. Three distinct groups of affected patients have been described: (1) human immunodeficiency virus-infected patients, (2) post-transplant patients, and (3) patients with congenital immunodeficiency. The tumors can develop anywhere in the body, with 17 reported cases occurring in the spinal canal, all in patients with human immunodeficiency virus infection. ⋯ Despite the growing number of case reports, this diagnosis presents a challenge, as the pathophysiology and optimal treatment regimens are not well understood. Results of a literature review of Epstein-Barr virus-associated SMT of the spine as well as a discussion of the presentation, management, and prognosis of this condition is presented here.
