Review Case ReportsTime course of recovery following poor-grade SAH: the incidence of delayed improvement and implications for SAH outcome study design.
Data regarding the time course of recovery after poor-grade subarachnoid hemorrhage (SAH) is lacking. Most SAH studies assess outcome at a single time point, often as early as 3 or 6 months following SAH. The authors hypothesized that recovery following poor-grade SAH is a dynamic process and that early outcomes may not always approximate long-term outcomes. To test this hypothesis, they analyzed long-term outcome data from a cohort of patients with poor-grade aneurysmal SAH to determine the incidence and predictors of early and delayed neurological improvement. ⋯ A substantial minority of poor-grade SAH patients will experience delayed recovery beyond the point at which most studies assess outcome. Younger patients, those presenting in better clinical condition, and those without CT evidence of large or eloquent stroke demonstrated the highest capacity for delayed recovery.

Society of Neurological Surgeons boot camp courses: knowledge retention and relevance of hands-on learning after 6 months of postgraduate year 1 training.
In July 2010, the Society of Neurological Surgeons (SNS) introduced regional courses to promote patient safety and teach fundamental skills and knowledge to all postgraduate Year 1 (PGY1) trainees entering Accreditation Council for Graduate Medical Education (ACGME)-accredited US neurosurgery residency programs. Data from these courses demonstrated significant didactic learning and high faculty and resident satisfaction with hands-on training. Here, the authors evaluated the durability of learning from and the relevance of participation in SNS PGY1 courses as measured midway through PGY1 training. ⋯ The learning and other benefits of participation in a national curriculum for residents entering PGY1 neurosurgical training were maintained 6 months after the courses, halfway through the initial training year.

Biography Historical ArticleWilliam P. Van Wagenen (1897-1961): pupil, mentor, and neurosurgical pioneer.
William Perrine ("Van") Van Wagenen (1897-1961) was the first Chief of Neurosurgery at the University of Rochester Medical Center (URMC), serving from 1928 to 1954, and was a leading figure in 20th-century neurosurgery. He was a devoted pupil of Dr. ⋯ Upon his death in 1961 he bequeathed an endowment for the Van Wagenen Fellowship, which has advanced the education of many leaders in American neurosurgery. His legacy of operative skill, his commitment to resident education and research in neurological disease, his inspiration for the foundation of the Cushing Brain Tumor registry, and his contributions to organized neurosurgery form the foundation of the legacy of neurosurgery at URMC.

Case ReportsLimitations of nerve repair of segmental defects using acellular conduits.
The authors present the case of a 20-year-old man who, 3 months after his initial injury, underwent repair of a 1.7-cm defect of the ulnar nerve at the wrist; repair was performed with an acellular nerve allograft. Given the absence of clinical or electrophysiological recovery at 8 months postrepair, the patient underwent reexploration, excision of the "regenerated cable," and rerepair of the ulnar nerve with sural nerve autografts. ⋯ At the 6- and 12-month follow-ups of the sural nerve graft repair, clinical and electrophysiological evidence of both sensory and motor reinnervation of the ulnar nerve and associated hand muscles was demonstrated. In this report, the authors describe a single case of failed acellular nerve allograft and correlate the results with basic science and human studies reporting length and diameter limitations in human nerve repair utilizing grafts or conduits devoid of viable Schwann cells.
