Extensive Spinal Epidural Abscess: A Systematic Review of Risk Factors, Clinical Presentation, and Management with a Case Illustration.
Extensive spinal epidural abscess (ESEA) is a rare clinical entity subject to delayed diagnosis, which can be explained by the extension of the epidural collection, thereby delaying the mass effect responsible for its clinical manifestations. ⋯ Both single and multilevel laminectomy with abscess drainage for ESEA leads to patient recovery from this devastating condition. Evaluation of the outcome with data on time-to-Nadir and Nadir-to-surgery is needed to codify ESEA management.

This study examined clinical outcomes associated with 3 types of noncontiguous cervical surgeries - anterior cervical discectomy and fusion (ACDF), cervical disc arthroplasty (CDA), and hybrid cervical surgery (HCS) - to improve surgeon decision-making. ⋯ There may be no clinically meaningful difference in many clinical outcomes for different non-contiguous surgical interventions for non-contiguous cervical degenerative disc disease (CDDD). However, complication rates, such as dysphagia and ASD, appear higher for non-contiguous ACDF as compared to non-contiguous CDA or HCS.

The Link between Vitamin D and the Risk of Aneurysmal Subarachnoid Hemorrhage: A Systematic Review.
Vitamin D (VD) is one of the fat-soluble vitamins proposed to be associated with aSAH. According to the clinical evidence, this investigation explores the link between VD concentrations and clinical outcomes in aSAH patients. ⋯ This study highlights the complex association between VD concentration and the risk of aSAH. The observed inconsistencies in study outcomes suggest that the relationship between VD and aSAH is multifaceted and may be influenced by various factors, including study population, geographical location, and methodological approach.

Review Case Reports
Management of recurrent cerebrospinal fluid rhinorrhea caused by sequential, anatomically separated skull base defects - A case-based systematic review.
Recurrent cerebrospinal fluid (CSF) rhinorrhea caused by sequential, anatomically separated skull base defects is rarely reported in the literature. Neither management nor etiology has been sufficiently investigated. We present an illustrative case and a systematic review of the literature regarding etiology, diagnostics, and management of this rare phenomenon. ⋯ Occurrence of recurrent CSF rhinorrhea due to an anatomically separated sequential skull base lesion remains a rare phenomenon. Reassessment of imaging studies and a structured diagnostic workup to detect sequential CSF leaks independent of the primary lesion should is recommended.

One of the pressing constraints in the treatment of arteriovenous malformations (AVM) is the potential development of new neurologic deficits, mainly when the AVM is in an eloquent area. The risk of ischemia when an en passage arterial supply is present is not negligible. In this regard, awake surgery holds promise in increasing the safety of low-grade AVM resection. ⋯ Awake craniotomies are safe procedures and may be helpful in avoiding ischemic complications in low-grade AVMs, either affecting eloquent areas and/or when en passage feeders are present.
