Daniel Ruge: the first neurosurgeon to serve as physician to the president.
The role of chief White House physician has traditionally been held by an individual with a background in a broad medical field, such as emergency medicine, family medicine, or internal medicine. Dr. Daniel Ruge, who served as the director of the Spinal Cord Injury Service for the Veterans Administration and was appointed during President Ronald Reagan's first term, was the first neurosurgeon to become the chief White House physician. ⋯ Dr. Ruge's actions after the assassination attempt on President Reagan resulted in the rapid, smooth recovery of the then-president. Daniel Ruge's background, his high-profile roles and heavy responsibilities, and his critical decision-making are characteristics that make his role in the history of medicine and of neurosurgery unique.

Rear Admiral (Astronaut) Alan Shepard: Ménière's disease and the race to the moon.
On May 5, 1961, Alan B. Shepard Jr. piloted the Freedom 7 craft into a suborbital flight to become the first American man in space. His promising astronautical career was soon scuttled by spells of dizziness and tinnitus later diagnosed as Ménière's disease, until William F. ⋯ In 1968 House implanted an endolymphatic-subarachnoid shunt, which at the time was a virtually experimental procedure. Shepard's debilitating Ménière's disease was cured, but not quite in time for him to pilot the doomed Apollo 13 mission; he was reassigned to Apollo 14 and as a result would step foot on the moon on February 5, 1971. This historical vignette depicts the tale of how the career trajectories of Shepard and House-two notable figures in their respective fields-fatefully intersected.

Endonasal endoscopic resection of olfactory neuroblastoma: an 11-year experience.
Olfactory neuroblastoma (ONB) is a rare malignant neoplasm of the sinonasal cavity. Surgery has been and remains a mainstay of treatment for patients with this tumor. Open craniofacial resections have been the treatment of choice for many decades. More recently, experience has been growing with endoscopic approaches in the management of patients with ONB. The object of this study is to report the authors' experience over the past 11 years with ONB patients treated with purely endonasal endoscopic techniques. ⋯ The current results provide additional evidence for the continued use of endoscopic procedures in the management of this malignancy.

Development of a performance model for virtual reality tumor resections.
Previous work from the authors has shown that hand ergonomics plays an important role in surgical psychomotor performance during virtual reality brain tumor resections. In the current study they propose a hypothetical model that integrates the human and task factors at play during simulated brain tumor resections to better understand the hand ergonomics needed for optimal safety and efficiency. They hypothesize that 1) experts (neurosurgeons), compared to novices (residents and medical students), spend a greater proportion of their time in direct contact with critical tumor areas; 2) hand ergonomic conditions (most favorable to unfavorable) prompt participants to adapt in order to optimize tumor resection; and 3) hand ergonomic adaptation is acquired with increasing expertise. ⋯ The study results confirm the experts' (neurosurgeons) greater capacity to adapt their hand ergonomics during simulated neurosurgical tasks. The proposed hypothetical model integrates the study findings with various human and task factors that highlight the importance of learning in the acquisition of hand ergonomic adaptation.

Subcortical stimulation mapping of descending motor pathways for perirolandic gliomas: assessment of morbidity and functional outcome in 702 cases.
Herein, the authors report their experience with intraoperative stimulation mapping to locate the descending subcortical motor pathways in patients undergoing surgery for hemispheric gliomas within or adjacent to the rolandic cortex, with particular description of the morbidity and functional outcomes associated with this technique. ⋯ Stimulation mapping allows surgeons to identify the descending motor pathways during resection of tumors in perirolandic regions and to attain an acceptable rate of morbidity in these high-risk cases.
