Central neurocytomas (CNCs) are rare intraventricular lesions comprising <1% of primary brain tumors. Their surgical and adjuvant management is unclear. ⋯ RT remains an important adjuvant treatment that can improve patient survival in the presence of MSR to levels comparable to those of GTR or GTR + RT. Where total resection carries too much risk, MSR + RT can be considered as the next best alternative for tumor control.

Review Meta Analysis
Assessing the Effects of Publication Bias on Reported Outcomes of Cervical Disc Replacement and Anterior Cervical Discectomy and Fusion: A Meta-Epidemiological Study.
There have been several clinical trials as well as observational studies that have compared the outcomes of different cervical disc replacement (CDR) devices with anterior cervical disc replacement and fusion (ACDF). Although the results of these studies have provided sufficient evidence for the safety of CDR, there is still a lack of consensus in terms of longer-term outcomes, with studies providing equivocal results for the 2 procedures. In the current study, we used a novel methodology, a meta-epidemiologic study, to investigate the impact of study characteristics on the observed effects in the literature on CDR and ACDF. ⋯ These results indicate that there may be a publication bias regarding the year of publication, with earlier studies reporting lower reoperation rates for CDR compared with ACDF.

Review Historical Article
Extensive pneumocephalus caused by multidrug-resistant Klebsiella pneumoniae.
The practice of surgical intervention for the treatment of psychiatric disorders has a rich and fascinating history. Arguably dating back to more than 7 millennia ago, neurosurgery for psychiatric disease is shrouded in stigma, being widely portrayed in the media (almost invariably negatively). ⋯ The landscape of neurosurgery for psychiatric conditions has shifted constantly since, guided by new developments in neuroscience and surgical technology. In this article, we outline the salient events in the story of this field.

Cavernous sinus dural arteriovenous fistulas (CS dAVFs) occasionally behave aggressively (e.g., intracranial hemorrhage, venous infarction, seizures) depending on the drainage flow and presence of a collateral route of cortical or basal cerebral venous drainage. When a CS dAVF with aggressive behavior is encountered, a radical cure is required to avoid catastrophic deficits. However, conventional transvenous cavernous sinus (CS) embolization via the inferior petrosal sinus does not always achieve shunt obliteration. We herein report a case of surgical venous drainage disconnection in an 83-year-old woman with a CS dAVF. ⋯ Surgical venous drainage disconnection from the fistulous point may be an alternative radical therapy for CS dAVFs with aggressive behaviors.

Atlantoaxial spine surgery is a challenge to spinal surgeons because of its proximity to neurovascular structures. This study aimed to identify and analyze the scientific publications in atlantoaxial spine surgery from different countries and institutions. ⋯ The atlantoaxial spine surgery literature has grown continuously in recent years. The United States is the largest contributor in this field. Fixation and fusion are the most common areas, and fixation-related studies should be closely followed. The screw-rod fixation system is becoming increasingly popular.
