To investigate the acute and long-term effects of vitamin D supplementation on the recovery of patients with traumatic brain injury (TBI). ⋯ Administration of vitamin D supplements in mild-to-moderate TBI patients with significant vitamin D deficiency during the acute phase of the injury may improve long-term performance and cognitive outcomes. Therefore, the treatment strategies should be individually planned for the patients with TBI based on their baseline vitamin D level.

Embolization of the middle meningeal artery (MMA) has emerged as a minimally invasive means of managing subdural hematoma. The purpose of this study was to systematically review the literature on the safety and effectiveness of this treatment and to share our clinical experience. ⋯ MMA embolization of CSDH is safe and effective for CSDH treatment based on a documented recurrence rate of 3.6% and lack of reported complications.

Pituitary adenomas in elderly patients may become more common as the population ages. Surgical benefits, especially for visual outcome, after endoscopic endonasal transsphenoidal surgery for pituitary adenomas remain to be elucidated. This retrospective analysis investigated clinical factors affecting visual outcome. ⋯ Visual disturbances were improved postoperatively in most patients in both groups at similar rates, but preoperative and postoperative visual disturbances were more severe in elderly patients because the symptoms may have been masked by the presence of lens opacity. Early diagnosis and intervention may be required in elderly patients for better visual outcome.

Slit-ventricle syndrome (SVS) is a recognized complication of ventricular shunt malfunction, resulting in cyclical symptoms without ventricular dilatation. We present a case of SVS with transient, repetitive, and progressive signs of brainstem herniation evidenced by pupillary dilatation, posturing, and unresponsiveness, with diffuse voltage attenuation on electroencephalogram (EEG). ⋯ SVS can lead to severe intermittent brainstem herniation syndrome in the setting of shunt malfunction. Seizure diagnosis should be reserved for cases with proven functional shunt and EEG confirmation of epileptiform activity.

Hemostatic thrombin-gelatin matrix leading to intracranial cyst formation : case report.
Local hemostatic agents have been used in the neurosurgical field for many years; it is safe and efficient with no fatal complication reported in the literature. We routinely used a gelatin-thrombin hemostatic agent (FloSeal Hemostatic Matrix) for hemostasis in minimally invasive endoscopic-assisted surgery for more than 500 patients with intracerebral hemorrhage. However, 2 cases with sterile cyst formation were encountered. ⋯ These sterile cysts were very close to the ventricle wall on images. We hypothesized that cyst wall may be formed not only by hemostatic agent-related fibrosis and inflammation according to the previous literature review but also by the presence of the check valve mechanism between the cyst and the ventricle, which caused further dilation of the cyst.
