Post-conditioning with volatile anesthetics can create ischemic tolerance against cerebral ischemia-reperfusion injury. The present study was designed to determine whether delayed exposure to sevoflurane could induce ischemic tolerance and if this effect was dependent on increasing phosphorylated Akt-Ser473 and GSK-3β-Ser9 expression in the mitochondria, via a mechanism involving the PI3K/Akt pathway. ⋯ Our data suggested that delayed application of sevoflurane after reperfusion provides neuroprotection by activating phosphorylated Akt-Ser473 and GSK-3β-Ser9 in the mitochondria via the PI3K/Akt pathway.

Randomized Controlled Trial
A single preoperative dose of diclofenac reduces the intensity of acute postcraniotomy headache and decreases analgesic requirements over five postoperative days in adults: A single center, randomized, blinded trial.
Postcraniotomy headache causes considerable pain and can be difficult to treat. We therefore tested the hypothesis that a single 100-mg preoperative dose of diclofenac reduces the intensity of postcraniotomy headache, and reduces analgesic requirements. ⋯ Preoperative diclofenac administration reduces postcraniotomy headache and postoperative analgesic requirements - a benefit that persisted throughout five postoperative days.

Unilateral gaze palsy associated with internuclear ophthalmoplegia (INO), i.e., one-and-a-half syndrome, is well known. Exotropia can also be associated with INO, but it has been reported only rarely. We sought to determine the frequencies and courses of gaze palsy and exotropia in INO. ⋯ Exotropia is not uncommon in the acute stage of INO. However, it is often overlooked because of its short duration.

Brainstem gliomas are rare in adults and overall have superior survival outcomes compared to pediatric brainstem gliomas. ⋯ Survival outcomes for adult WHO Grade II to IV brainstem gliomas were similar to supratentorial IDH1 wild-type tumors of similar grade and histology. Potentially actionable mutations can be identified from small biopsy samples in a subset of adult brainstem gliomas.

This study examined components of the Sports Concussion Assessment Tool, 3rd Edition (SCAT3) and a vision-based test of rapid number naming (King-Devick [K-D]) to evaluate sports and non-sports concussion patients in an outpatient, multidisciplinary concussion center. While the Symptom Evaluation, Standardized Assessment of Concussion (SAC), modified Balance Error Scoring System (BESS), and K-D are used typically for sideline assessment, their use in an outpatient clinical setting following concussion has not been widely investigated. ⋯ This study demonstrates a novel use of sideline concussion assessment tools for evaluation in the outpatient setting, and implicates age and gender as predictors of outcomes for these tests.
