This study sought to assess clinical outcomes in patients receiving gamma knife radiosurgery (GK) for treatment of brain metastases from melanoma and evaluate for potential predictive factors. ⋯ GK achieves excellent local control and may improve outcomes as a component of a multidisciplinary treatment strategy. Distant brain failure and neurologic demise remain problematic and prospective trials are necessary.

The current approach for the diagnosis and repair of spontaneous and traumatic anterior skull-base defects is oulined, highlighting the controversies that exist in the field and describing the strategies required to access different segments of the anterior cranial fossa. ⋯ Endoscopic endonasal repair of CSF leaks and encephaloceles has evolved significantly during the past decade. The versatility of different endoscopic approaches through the four endonasal corridors allows for the endoscopic repair of almost all skull-base defects. The use of vascularized pedicled mucosal flaps has evolved to cover these defects as part of multilayered closure strategies.

Biography Historical Article
Antone Tarazi: the first Palestinian neurosurgeon and the first neurosurgeon in Jordan: a neurosurgeon of two countries.
Antone (Tony) Tarazi (1927-1999) was the first Palestinian neurosurgeon and the first neurosurgeon in Jordan. In 1952, Tarazi received his medical degree from the American University of Beirut in Lebanon. After completing neurosurgery training at the Montreal Neurological Institute in 1960, he returned to Palestine to practice neurosurgery in both Palestine and Jordan. ⋯ Tarazi was the president of the Palestinian Neurosurgical Society, a member of Jordan medical societies, and a member of the American Association of Neurological Surgeons. His continuous efforts to improve medical services extended beyond neurosurgery to many other fields. This article recounts Antone Tarazi's achievements and contributions to neurosurgery in Palestine and Jordan.

Multicenter Study
Multicenter registry of liquid embolic treatment of cerebral aneurysms.
The Cerebral Aneurysm Multicenter European Onyx trial was the first multicenter prospective case series using liquid embolization for cerebral aneurysms. It suggested a possible decreased risk for recanalization of smaller aneurysms compared with coil embolization. After publication of that trial, the Onyx HD embolic agent, injection devices, and treatment protocols have all been updated and improved to increase efficacy and decrease adverse events. We present the results from a multicenter registry of liquid embolization treatments using the current method and materials. We hypothesize that the evolution of this technique will result in lower complication and recanalization rates when compared with earlier series. ⋯ Recent advances in liquid embolization have led to decreased recanalization and complications. Liquid embolization is more likely to achieve a durable result in smaller aneurysms that have not been previously treated.

To report a minimally invasive, nontubular endoscopic technique to resect intraparenchymal brain tumors and assess the feasibility, safety, and surgical resection margins achievable by this novel technique. ⋯ Our experience demonstrates that resection of intraparenchymal tumors using a minimally invasive endoscopic technique is technically feasible and safe, achieves good tumor resection margins, and has some potential advantages over a traditional microscopic technique.
