Glioblastoma is the most common primary malignant brain tumor, with more than10,000 new cases each year in the United States. Significant basic science and clinical research has been devoted to understanding this disease, yet median survival with standard of care treatment remains approximately 15 months. ⋯ These advances have generated both prognostic information as well as a multitude of treatment targets that are just now coming into clinical practice. This article aims to provide a comprehensive update on the recent use of genetic profiling to identify the molecular pathways altered in glioblastoma and to describe ongoing clinical trials to exploit these pathways for treatment.

Superior laryngeal neuralgia (SLN) is a relatively rare disorder that is characterized by neck pain. There are only a few reported cases and treatment options for SLN to date. In this study, we report 3 patients with SLN who were treated with Gamma Knife radiosurgery (GKRS) at the time of diagnosis. ⋯ This preliminary report provides encouraging evidence that GKRS represents an effective, safe, and relatively durable noninvasive treatment option for patients with SLN.

Neuroglobin as a Novel Biomarker for Predicting Poor Outcomes in Aneurysmal Subarachnoid Hemorrhage.
Neuroglobin (Ngb) has a high affinity for oxygen and helps prevent hypoxic-ischemic brain damage. In this study we analyzed the relationship between Ngb levels and clinical outcomes of aneurysmal subarachnoid hemorrhage (aSAH). ⋯ Serum Ngb levels on day 2 after aSAH were strongly associated with poor outcomes in aSAH, suggesting that Ngb may be a novel biomarker for predicting poor outcomes in aSAH.

Routine preoperative blood testing has become a dogma. The general practice is to order preoperative workup as a knee-jerk response rather than individualize it for each patient. The fact that the bleeding brain tends to swell, which coupled with limited options for proximal control, packing, and overall hemostasis, leads to an overemphasis on the preoperative coagulation profile. ⋯ We conclude that patients without a history of coagulopathy and normal physical examination do not require routine coagulation screening before elective craniotomy.

To explore the value of the application of neuroendoscopy techniques in the treatment of ventriculoperitoneal (VP) shunt blockage. ⋯ Neuroendoscopy techniques can be used to reveal the various causes of shunt obstruction. Any attempt to extract the tube should be performed with the aid of a neuroendoscope. The 3 surgical revision strategies for a blocked catheter are described for the first time in the literature. These approaches can reduce the operation time, the incidence of intraventricular hemorrhage, and the risk of infection.
