Our purpose is to describe a method of resecting occipital pole gliomas through a keyhole lobectomy and share the patient outcomes of this technique. ⋯ Our study provides details on the technical aspects of occipital keyhole lobectomies and gives the outcomes of patients who have received an operation for tumors in this uncommon location. Taking white matter tract anatomy into consideration, we show that the keyhole method can be applied to gliomas of the occipital lobe.

Intraoperative monitoring of cochlear nerve action potential (CNAP) has been used in patients with small vestibular schwannoma (<15 mm) to preserve cochlear nerve function. We performed surgery for a larger vestibular schwannoma under CNAP monitoring with the aim of preserving cochlear nerve function, and compared the data with findings from 10 patients with hemifacial spasm who underwent microvascular decompression surgery. ⋯ CNAP monitoring is extremely useful for preserving the function of the unseen cochlear nerve during vestibular schwannoma surgery.

Bone cement augmentation procedures (vertebroplasty and kyphoplasty) are the primary treatments for osteoporotic vertebral compression fracture (VCF). However, these procedures are associated with various problems resulting in subsequent fracture. The purpose of this study was to evaluate the spinal instability factors related to subsequent fracture after vertebral augmentation procedures. ⋯ Predictive scores can be calculated and used to predict the possibility of subsequent fracture according to scores. Group D showed the highest predictive scores and will need more preventative treatment.

Although hyperglycemia is a serious complication of subarachnoid hemorrhage, its pathophysiologic mechanism based on neural circuitry has not been known. ⋯ There is an important linear relationship among the blood glucose levels, DND of the IC, and nodose ganglia and degenerated surface areas of IL following experimentally induced sylvian SAH.
