A Proposed Grading System for Posterior Atlanto-Occipital Membrane Complex Injuries on Cervical MRI.
The posterior atlantooccipital membrane complex consists of the posterior atlantooccipital membrane and posterior atlantoaxial membrane. Posttraumatic, posterior atlantooccipital membrane complex injuries may have varied appearances on cervical magnetic resonance imaging. The purpose of this study was to identify the different types of posterior atlantooccipital membrane complex injuries that occur in trauma patients. ⋯ A grading system for posterior atlantooccipital membrane complex injuries is proposed on the basis of these data: grade 1-edema confined to the posterior atlantooccipital and atlantoaxial membrane; grade 2-edema confined to the posterior atlantooccipital and atlantoaxial membrane and ligamentum nuchae; grade 3-stripping injury of the posterior atlantooccipital membrane with C1-C2 dorsal epidural hematoma; and grade 4-frank disruption of the posterior atlantooccipital membrane at C1 with edema in the remaining posterior atlantooccipital membrane complex.

Review Meta Analysis
A systematic review and meta-analysis of antiepileptic prophylaxis in spontaneous intracerebral hemorrhage.
Frequency of clinical seizures may be as high as 16% in patients with spontaneous intracerebral hemorrhage (ICH). Current guidelines recommend against antiepileptic drug (AED) prophylaxis, but this recommendation is based on older trials, and the effect of newer AEDs is uncertain. The aim of this review was to study effects of AEDs on seizure occurrence and outcome in patients with spontaneous ICH. ⋯ This systematic review and meta-analysis including recent studies focusing on newer AEDs supports the 2015 guidelines regarding AED use in spontaneous ICH. There are some important caveats, including a possible confounding association between AED use and higher ICH score and the overall poor quality of the available data. A randomized clinical trial may be helpful.

Meta Analysis
Expandable versus Static Cages in Minimally Invasive Lumbar Interbody Fusion: A Systematic Review and Meta-analysis.
Expandable cages for interbody fusion allow for in situ expansion optimizing fit while mitigating endplate damage. Studies comparing outcomes after using expandable or static cages have been conflicting. ⋯ Expandable interbody cages in MIS-LIF were associated with a decrease in subsidence rate, operative time and greater in increase in disc height.

The best surgical treatment for adult Chiari malformation type 1 remains widely debated. ⋯ Posterior fossa decompression and duraplasty with arachnoid preservation is a beneficial technique to treat Chiari malformation type 1 and reduces the risk of complications, particularly cerebrospinal fluid-related complications and the rate of reoperation.

Review Meta Analysis
Near-Infrared Spectroscopy in Neurocritical Care: a Review of Recent Updates.
Neurocritical diseases and conditions are common causes of long-term disability and mortality. Early recognition and management of neurocritically ill patients is a significant challenge for neurosurgeons, neurologists, and neurointensivists. Although cerebral angiography, magnetic resonance imaging, computed tomography, and radionuclide imaging are useful in neuromonitoring and neuroimaging, they have several important limitations: they are not readily available, cannot be used for a continuous assessment of cerebral function, and frequently require patient transport to the radiological department. ⋯ NIRS can detect and monitor multiple critical parameters, including cerebral oximetry, intracranial pressure, temperature, and cerebral blood flow. NIRS can be valuable for a wide variety of neurocritical diseases and conditions, such as ischemic and hemorrhagic strokes, severe traumatic brain injury, brain tumors, and perioperative neurosurgery. Although NIRS has been studied extensively in multiple neurocritical conditions, more evidence on its application is needed.
