Comparative Study Clinical Trial
Comparative Cohort Study of Percutaneous Pedicle Screw Implantation without Versus with Navigation in Patients Undergoing Surgery for Degenerative Lumbar Disc Disease.
The major limitation of computer-based three-dimensional fluoroscopy is increased radiation exposure of patients and operating room staff. Combining spine navigation with intraoperative three-dimensional fluoroscopy (io3DF) can likely overcome this shortcoming, while increasing pedicle screw accuracy rate. We compared data from a cohort of patients undergoing lumbar percutaneous pedicle screw placement using io3DF alone or in combination with spine navigation. ⋯ io3DF with spine navigation minimized radiation exposure of patients and operating room staff and provided an excellent percutaneous pedicle screw accuracy rate with no permanent complications compared with io3DF alone. This setup is recommended, especially for patients with a complex degenerative spine condition.

Acoustic neuroma is the most common extra-axial primary cerebellopontine angle tumor in adults. A plethora of studies have been published on acoustic neuroma, but none of the previous works have highlighted the most influential articles. Our objective was to perform a bibliometric analysis of the 50 most-cited articles on acoustic neuroma. ⋯ Identifying articles on acoustic neuroma with the most impact provides an important overview of the historical development of treatment methods and publication trends related to this condition. A finalized, comprehensive list of the most important works represents an excellent tool that can serve as a guide for evidence-based clinical practice.

Soccer, bicycling, and horseback riding are sports most commonly associated with traumatic brain injury (TBI) in Germany. The latter 2 sports activities are commonly practiced with helmets, and data on helmet use and usefulness vary widely. ⋯ We gained important epidemiologic data on pediatric TBI in our region. Despite the descriptive nature of the data, a trend toward reduced odds of loss of consciousness was seen in the helmet wearers. Nevertheless, serious injury can occur despite helmet use.

Case Reports
Rapid-Onset Thoracic Myelopathy due to an Epidural Sarcoid-Like Lesion in a Pediatric Patient.
Isolated intraspinal neurosarcoidosis is a rare clinical entity, with most reports describing intramedullary involvement in adults. ⋯ Although less likely than neoplasia, rheumatologic processes such as inflammatory granulomatous disease warrant consideration in similar cases.

Herpes zoster ophthalmicus (HZO) is caused by reactivation of the herpes simplex virus in the trigeminal nerve. HZO-initiated cerebral vasculopathy is well characterized; however, there are no documented cases that report the efficacy of surgical revascularization for improving cerebral hemodynamics following progressive HZO-induced vasculopathy. We present a case in which quantitative anatomic and hemodynamic imaging were performed longitudinally before and after surgical revascularization in a patient with HZO and vasculopathic changes. ⋯ HZO can lead to progressive, symptomatic intracranial stenoses. This report suggests that surgical revascularization techniques can improve cerebral hemodynamics and symptomatology in patients with aggressive disease when medical management is unsuccessful; similar procedures could be considered in managing HZO patients with advanced or progressive vasculopathy.
