Meningioma, a common primary brain tumor in adults, is graded based on World Health Organization criteria that rely on histology alone. This approach is unable to determine conclusively which tumors, especially benign or atypical, will recur. ⋯ Immunotherapy is also being trialed in treating high-grade and recurrent meningioma. This review summarizes recent developments characterizing meningioma using genetic and immunologic biomarkers and how these molecular tools may be integrated into existing care together with current World Health Organization grading to improve diagnosis, prognosis, and therapy.

Multicenter Study Observational Study
Intelligent Surgeon's Arm Supporting System iArmS in Microscopic Neurosurgery Utilizing Robotic Technology.
Based on our previous reports, stabilizing the surgeon's arm with an intraoperative armrest is linked to improved precision of microsurgical and endoscopic procedures. We developed the robotic intelligent surgeon's arm supporting system iArmS, which automatically follows the surgeon's arm and fixes it at an adequate position. ⋯ iArmS allows continuous precise manipulations that provide high-quality surgical results in neurosurgical techniques. Moreover, iArmS is a useful automatic tool for holding and following the surgeon's arm.

Review Case Reports
Traumatic Unilateral L3-4 Jumped Facet Treated with Open Reduction and Short Segment Fusion.
Facet dislocations, or jumped facets, are part of a spectrum of flexion-distraction spine injuries. Bilateral and unilateral facet dislocations are commonly seen in the cervical spine. Traumatic jumped facets in the lumbar spine are rare injuries, and most involve the lumbosacral junction. Lumbar facet subluxations occur commonly in young patients owing to flexion-distraction forces on the lumbar spine at the time of injury combined with ligamentous laxity that exists in young patients. ⋯ Following anatomic reduction, unilateral jumped facets can be effectively treated with instrumented stabilization. This report provides evidence for the durability of short segment arthrodesis in select cases of a rare lumbar facet subluxation.

Comparative Study
Stereoscopic versus monoscopic viewing of aneurysms: experience of a single institution with a novel stereoscopic viewing system.
Stereoscopic viewing of computed tomographic angiography (CT-A) or magnetic resonance angiograms might increase the diagnostic potential of these imaging techniques. Our aim was to evaluate the benefits of a novel stereoscopic viewing system for aneurysm detection compared with standard monoscopic viewing. ⋯ Stereoscopic viewing of CT-As increases the diagnostic accuracy and represents a promising technique to reduce the need for invasive DSA.

The efficacy of tranexamic acid to control blood loss from lumbar spinal fusion surgery remains controversial. We conducted a systematic review and meta-analysis to explore the influence of tranexamic acid on blood loss from lumbar spinal fusion surgery. ⋯ Tranexamic acid has an important ability to decrease intraoperative blood loss and hospitalization for lumbar spinal fusion surgery.
