Glioma and meningioma are the most common primary brain tumors in adults. Epidemiologic studies of the relationship between female hormone exposure and exogenous hormone use and the risk of meningioma and glioma in females have yielded inconsistent results. ⋯ OC use may not increase the risks of glioma and meningioma in females. Instead, the long-term use of OCs may significantly decrease the risk of glioma, and the benefits are even more pronounced when the time window is >7.5 years. Nonetheless, the pooled results in this study suggest that OC use may not increase the risk of meningioma. Therefore, our conclusion should be validated and supplemented in future larger studies.

Review Historical Article
The Original Cushing Society: A Historical Review of the Senior Society's First 6 Meetings.
The Society of Neurological Surgeons (SNS), founded in 1920, is one of the oldest neurosurgical society in the world. The founding members were prominent surgeons that met with the idea of furthering the field of neurosurgery. Initial meetings were forums to observe and discuss new surgeries. ⋯ Cases that ultimately changed the practice of neurosurgery at that time will be profiled. The SNS began as a traveling club of neurosurgical leaders who learned from each other's clinical experience to mold this burgeoning new field. However, the members made an impact on how neurosurgery was practiced nationally.

The extreme lateral supracerebellar infratentorial (ELSI) approach has the potential to access several distinct anatomical regions that are otherwise difficult to reach. We have illustrated the surgical anatomy through cadaveric dissections and provided an extensive review of the literature to highlight the versatility of this approach, its limits, and comparisons with alternative approaches. ⋯ The ELSI approach represents one of the most versatile approaches with respect to its ability to address several anatomical regions centered at the posterior and middle incisural spaces. For intra-axial pathologies, the approach allows for access to the central core of the brain with several advantages compared with alternate approaches that frequently involve significant brain retraction and cortical incisions. In specific cases of skull base lesions, the ELSI approach is an elegant alternative to traditionally used skull base approaches, thereby avoiding approach-related morbidity.

Lesioning the Forel field or the subthalamic region is considered a possible treatment for tremoric patients with Parkinson disease, essential tremor, and other diseases. This surgical treatment was performed in the 1960s to 1970s and was an alternative to thalamotomy. Recently, there has been increasing interest in the reappraisal of stimulating and/or lesioning these targets, partly as a result of innovations in imaging and noninvasive ablative technologies, such as magnetic resonance-guided focused ultrasonography. ⋯ Based on the significant breakthrough that magnetic resonance-guided focused ultrasonography has meant in the neurosurgical world, some classic targets such as the pallidothalamic tract, Forel field, and posterior subthalamic area may be reconsidered as surgical alternatives for patients with movement disorders.

This study set out to investigate the relationships between the neutrophil-to-albumin ratio (NAR) in the early stages of aneurysmal subarachnoid hemorrhage (aSAH) and the occurrence of delayed cerebral ischemia (DCI). ⋯ NAR, in positive correlation with the severity of hemorrhage, appears to be a novel predictive biomarker of DCI after aSAH.
