Review Meta AnalysisInsular epilepsy surgery: lessons learned from institutional review and patient-level meta-analysis.
Insular lobe epilepsy is a challenging condition to diagnose and treat. Due to anatomical intricacy and proximity to eloquent brain regions, resection of epileptic foci in that region can be associated with significant postoperative morbidity. The aim of this study was to review available evidence on postoperative outcomes following insular epilepsy surgery. ⋯ These findings may serve as a benchmark when tailoring decision-making for insular epilepsy, and may assist surgeons in their preoperative discussions with patients. Although seizure freedom rates are quite high with insular epilepsy treatment, the associated morbidity needs to be weighed against the potential for seizure freedom.

Review Meta AnalysisFormation of intracranial de novo aneurysms and recurrence after neck clipping: a systematic review and meta-analysis.
Incidence rates of de novo aneurysm formation and recurrence after clip ligation remain controversial. In this meta-analysis, the authors provide data on pooled annual incidence rates and the association of patient characteristics with time to formation of de novo aneurysms and time to recurrence after clipping. ⋯ Despite low reported annual incidence rates, the cumulative risk of 9.6%-22% for aneurysm recurrence or de novo formation 20 years after clip ligation warrants lifelong follow-up. Screening at 5, 10, and 20 years would detect 30.8% (95% CI 23.3%-37.6%), 64.2% (95% CI 55.9%-70.9%), and 95.9% (95% CI 90.9%-97.9%) of de novo aneurysms. Screening for recurrent aneurysms at 10, 15, and 20 years would detect 36.6% (95% CI 26.5%-45.4%), 65.3% (95% CI 54.7%-73.5%), and 95.1% (95% CI 85.8%-96.6%) of lesions.

Review Meta AnalysisSurgical management of camptocormia in Parkinson's disease: systematic review and meta-analysis.
Camptocormia is a potentially debilitating condition in the progression of Parkinson's disease (PD). It is described as an abnormal forward flexion while standing that resolves when lying supine. Although the condition is relatively common, the underlying pathophysiology and optimal treatment strategy are unclear. In this study, the authors systematically reviewed the current surgical management strategies for camptocormia. ⋯ Surgical options include transient, external spinal stimulation; DBS targeting the subthalamic nuclei; and spinal deformity surgery. Benefit from DBS stimulation was inconsistent. Spine surgery corrected spinal imbalance but was associated with a high complication rate.

Meta Analysis Comparative StudyPhenytoin versus levetiracetam as prophylaxis for postcraniotomy seizure in patients with no history of seizures: systematic review and meta-analysis.
OBJECTIVEDe novo seizure following craniotomy (DSC) for nontraumatic pathology may adversely affect medical and neurological outcomes in patients with no history of seizures who have undergone craniotomies. Antiepileptic drugs (AEDs) are commonly used prophylactically in patients undergoing craniotomy; however, evidence supporting this practice is limited and mixed. The authors aimed to collate the available evidence on the efficacy and tolerability of levetiracetam monotherapy and compare it with that of the classic AED, phenytoin, for DSC. ⋯ However, the discontinuation rate of AEDs due to ADR was 53/297 in the phenytoin group and 6/196 in the levetiracetam group (POR 0.266, 95% CI 0.137-0.518, p < 0.001). CONCLUSIONSLevetiracetam is superior to phenytoin for DSC prevention for nontraumatic pathology and has fewer serious ADRs that lead to discontinuation. Further high-quality studies that compare levetiracetam with placebo are necessary to provide evidence for establishing AED guidelines.

Meta AnalysisChemical venous thromboembolism prophylaxis in neurosurgical patients: an updated systematic review and meta-analysis.
Venous thromboembolism (VTE) is a common and potentially life-threatening complication. The risk of serious hemorrhagic complications when starting chemical prophylaxis for VTE prevention is a substantial concern for neurosurgeons. The objective of this study was to perform an updated systematic review and meta-analysis to determine if the rates of VTE and bleeding complications are different in patients undergoing chemoprophylaxis compared with placebo or mechanical prophylaxis alone following cranial or spinal procedures. ⋯ Based on moderate-to-good quality of evidence, chemoprophylaxis is beneficial in preventing VTE, with no significant increase in either major or minor bleeding complications in patients undergoing cranial and spinal procedures. Further research is needed to determine whether this conclusion holds true for more specific subpopulations.
