To update outcomes and assess prognostic factors in the modern, multimodality treatment of patients with pineoblastoma. ⋯ Modern, multimodality treatment of pineoblastoma yields a high rate of overall survival, with acceptable short- and long-term toxicity. A greater M-stage at presentation and development of disease recurrence correlate with worse overall survival. Patients who received focal radiation initially experienced a greater rate of disease recurrence compared with those treated to the craniospinal axis.

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.

Different surgical approaches have been used over the years in order to access skull base. The endoscopic endonasal approach represents a direct and minimally invasive approach to the suprasellar, retrosellar, and retroclival space, with the advantage of avoid brain retraction and visualize safely and effectively the surgical target. The present contribution aims to provide anatomical details of the skull base as seen from below (i.e., via an endoscopic endonasal approach). ⋯ The development of endoscopic techniques has opened different perspectives over the skull base surgery. Endonasal surgery provides access to a wide range of skull base lesions via a natural surgical corridor (i.e., the nasal cavities).

To describe our designed protocol for the reconstruction of three-dimensional (3D) models applied to various endoscopic endonasal approaches that allows performing a 3D virtual dissection of the desired approach and analyzing and quantifying critical surgical landmarks. ⋯ The methodology for surgical training in the anatomic laboratory described in this article has proven to be very effective, producing a depiction of anatomic landmarks as well as 3D visual feedback that improves the study, design, and execution in various neurosurgical approaches. The Dextroscope as a virtual surgery simulation system can be used as a preoperative planning tool that can allow the neurosurgeon to perceive, practice reasoning, and manipulate 3D representations using the transsphenoidal perspective acquiring specifically visual information for endoscopic endonasal approaches to the skull base. The Dextroscope also can be used as an advanced tool for analytic purposes to perform different types of measurements between surgical landmarks before, during, and after dissection.

The aims of this study were to determine the efficacy and feasibility of implementation of the intraoperative component of a high risk spine (HRS) protocol for improving perioperative patient safety in complex spine fusion surgery. ⋯ The intraoperative component of the HRS protocol, based on two Do-Confirm checklists that focused on 1) organized communication between intraoperative team members and 2) active maintenance of oxygen delivery and hemostasis appears to maintain a safe intraoperative environment and was readily implemented during a 3-year period.
