Review
Top 100 most-cited articles on Spontaneous Intracerebral Hemorrhage: A bibliometric analysis.
A bibliometric uses the citation count of an article to determine its impact on the clinical world. There is a paucity of literature concerning top article citations on spontaneous intracerebral hemorrhage (ICH). The main objective of this investigation was to bridge this gap and to provide understanding of the trends on the most influential articles written on this subject. ⋯ Our study identifies the trends related to spontaneous ICH by analyzing the citation frequency of the most-cited articles in the field.

Meta Analysis
Association of SOX17 Gene Polymorphisms and Intracranial Aneurysm: A Case-Control Study and Meta-Analysis.
Genome-wide association studies have revealed an association between SRY-box 17 (SOX17) gene and intracranial aneurysm (IA) formation. However, results were mainly derived from European and Japanese populations. We investigated the association between SOX17 gene polymorphisms and IA in a homogeneous Korean population. We performed a meta-analysis to assess these results in East-Asian populations. ⋯ Identification of genetic variants located near SOX17 is likely to be clinically significant for IA formation. rs10958409 and rs9298506 may increase risk of IA in East-Asian populations. Our findings may help in the identification of IA pathogenesis.

Randomized Controlled Trial Comparative Study
Comparison of clinical and radiographic outcomes for posterior fossa decompression with and without duraplasty for treatment of pediatric Chiari I malformation: a prospective study.
The aim of this study was to prospectively compare the radiographic and clinical outcomes between the posterior fossa decompression (PFD) and PFD with duraplasty (PFDD) procedures in adolescent patients with Chiari malformation type I (CMI). ⋯ Compared with the more aggressive decompression with duraplasty, PFD without duraplasty produces comparable radiologic and clinical outcomes and is associated with a lower risk of complications.

Neurosurgical educators strive to identify the best applicants, yet formal study of resident selection has proved difficult. We conducted a systematic review to answer the following question: What objective and subjective preresidency factors predict resident success? ⋯ Standardized testing most strongly correlated with future examination performance but correlated poorly with faculty evaluations. Moderate predictors of faculty evaluations were aggregate rank scores, letters of recommendation, and athletic or musical talent. The ability to predict success of neurosurgical residents using an evidence-based approach is limited, and few factors have correlated with future resident performance. Given the importance of recruitment to the greater field of neurosurgery, these data provide support for a national, prospective effort to improve the study of neurosurgery resident selection.

Review Case Reports
The relationship between hematoma and pachymeninges in an interdural hematoma: diagnosis and surgical strategy.
The exact location of a hematoma in relation to the pachymeninges contributes to typical radiographic presentations. However, because of the complexity of hematoma evolution and neomembrane formation, an unexpected intraoperative finding can lead to a change of surgical strategy. In addition, the concentration of hemoglobin and its degradation products, the integrity of red blood cells, and the infiltration of fibroblasts, polymorphonuclear neutrophils, and macrophages are factors that affect the imaging characteristics on computed tomography and magnetic resonance imaging as the hematoma ages. ⋯ A careful evaluation of cerebral expansion before membranectomy was mandatory intraoperatively. For IDH, wide inner membranectomy (i.e., excision of meningeal dura mater) should not be necessary. An IDH should be considered as a distinct disease category when evaluating an extra-axial hematoma despite its rarity, because the characters of radiologic, histopathologic findings are different. In addition, surgical strategy varies for epidural or subdural hematoma in different hematoma stages.
