Multicenter Study
Assessment of a novel adult cervical deformity frailty index as a component of preoperative risk stratification.
To determine the value of a novel adult cervical deformity frailty index (CD-FI) in preoperative risk stratification. ⋯ Greater frailty was associated with greater risk of major complications for patients undergoing cervical spine deformity surgery. The CD-FI may be used to improve the accuracy of preoperative risk stratification and allow for adequate patient counseling.

Subarachnoid hemorrhage (SAH) is managed across the full spectrum of healthcare, from clinical diagnosis to management of the hemorrhage and associated complications. Knowledge of the pathogenesis and pathophysiology of SAH is widely known; however, a full understanding of the underlying molecular, cellular, and circulatory dynamics has still to be achieved. Intracranial complications including delayed ischemic neurologic deficit (vasospasm), rebleed, and hydrocephalus form the targets for initial management. However, the extracranial consequences including hypertension, hyponatremia, and cardiopulmonary abnormalities can frequently arise during the management phase and have shown to directly affect clinical outcome. This review will provide an update on the pathophysiology of SAH, including the intra- and extracranial consequences, with a particular focus on the extracranial consequences of SAH. ⋯ Although the intracranial complications of SAH can take priority in the initial management, the extracranial complications should be monitored for and recognized as early as possible because these complications can develop at varying times throughout the course of the condition. Therefore, a variety of investigations, as described by this article, should be undertaken on admission to maximize early recognition of any of the extracranial consequences. Furthermore, because the extracranial complications have a direct effect on clinical outcome and can lead to and exacerbate the intracranial complications, monitoring, recognizing, and managing these complications in parallel with the intracranial complications is important and would allow optimization of the patient's management and thus help improve their overall outcome.

Review Biography Historical Article
Paul of Aegina (625-690), his work and his contribution to neurological surgery: trephinations and laminectomies in the Dark Ages.
The purpose of this historical review is to summarize the work of Paul of Aegina, especially his contribution to the treatment of neurosurgical disorders and trauma. Paul performed trephinations for head injuries in the tradition of the Egyptian and the Greek schools of medicine. However, he was an innovator in the treatment of several spine injuries, as his choice to perform laminectomies and his description of them as safe and successful is unprecedented in the history of the recorded medicine and surgery. ⋯ Thus, he may be considered the historic father of spine surgery for his pioneering surgical innovations. This shows clearly that innovation in science and medicine was significantly increased through the rise of Islam and the Arabic conquest of the Middle East. The so-called "Dark Ages" were not so dark after all.

We investigated the prevalence, onset, characteristics, and long-term course of epilepsy disease in children who underwent surgical intervention for diagnosed brain tumors. ⋯ We show a high incidence of epilepsy in the late course of pediatric brain tumor disease. In the long term, seizure outcome was excellent. However, postsurgical onset of epilepsy was associated with a less favorable neurologic outcome.

Three-dimensional (3D) time of flight (TOF) imaging is the current gold standard for noninvasive, preoperative localization of lenticulostriate arteries (LSAs) in insular gliomas; however, the utility of this modality depends on tumor intensity. ⋯ Contrast-enhanced 3D TOF can delineate LSAs in almost all insular gliomas but is limited in identifying the LSA-tumor interface. This limitation can be overcome by addition of analogous CISS sequences that delineate the LSA-tumor interface regardless of tumor intensity. Combined 3D TOF and 3D CISS is a useful tool for surgical planning and safer resections of insular tumors and may have added surgical relevance when included as an intraoperative adjunct.
