The impact of provider surgical volumes on survival in children with primary tumors of the central nervous system--a population-based study.
Provider volume is often a central topic in debates about centralization of procedures. In Norway, there is considerable variation in provider volumes of the neurosurgical centers treating children. We sought to explore long-term survival after surgery for central nervous system tumors in children in relation to regional provider volumes. ⋯ In this population-based study of children operated over a period of two decades, we found no evidence of improved long-term survival in the high-provider volume region. Surprisingly, a subgroup analysis indicated that survival in PNET/medulloblastomas was significantly better if living outside the most populated health region with the highest provider volumes. One should, however, be careful of interpreting this directly as a symptom of quality of care, as there may be unseen confounders. Our study demonstrates that provider case volume may serve as an axiom in debates about centralization of cancer surgery while perhaps much more reliable and valid but less quantifiable factors are important for the final results.

Biography Historical ArticleHarvey Cushing's case series of trigeminal neuralgia at the Johns Hopkins Hospital: a surgeon's quest to advance the treatment of the 'suicide disease'.
A review of Dr. Harvey Cushing's surgical cases at the Johns Hopkins Hospital provided insight into his early work on trigeminal neuralgia (TN). There was perhaps no other affliction that captured his attention in the way that TN did, and he built a remarkable legacy of successful treatment. At the time, surgical interventions carried an operative mortality of 20%. ⋯ Modern day interventions of TN are reflective of the legacy left to us by Harvey Cushing, a pioneering forefather in neurosurgery. He pioneered the infra-arterial approach to excision of the Gasserion ganglion in face of problematic bleeding and later the use of sensory root avulsion to spare motor function. Through the evolution of his legacy and the refinement of original approaches, the quest to advance the treatment of TN took him along the trigeminal nerve from the periphery into the brain.

Case Reports Comparative StudySurgical intervention for severe head injury: ethical considerations when performing life-saving but non-restorative surgery.
The aim of this study was to compare the predicted outcome with observed outcome in those patients who have had a unilateral decompressive craniectomy following evacuation of an intracranial mass lesion and to consider some of the ethical issues that need to be addressed when performing life-saving but non-restorative surgery. ⋯ As the index of injury severity (as adjudged by the CRASH outcome prediction model) increases, clinical decision making and discussion with surrogates must reflect the evidence provided by observed outcome, prior to life-saving but potentially non-restorative decompressive surgery.
