External ventricular drain practice variations: results from a nationwide survey.
OBJECTIVE While guidelines exist for many neurosurgical procedures, external ventricular drain (EVD) insertion has yet to be standardized. The goal of this study was to survey the neurosurgical community and determine the most frequent EVD insertion practices. The hypothesis was that there would be no standard practices identified for EVD insertion or methods to avoid EVD-associated infections. ⋯ CONCLUSIONS This survey demonstrated heterogeneity in the practices for EVD insertion. No standard practices have been proposed or adopted by the neurosurgical community for EVD insertion or complication avoidance. These results highlight the need for the nationwide standardization of technique and complication prevention measures.

An analysis of malpractice litigation related to the management of brain aneurysms.
OBJECTIVE Given the highly complex and demanding clinical environment in which neurosurgeons operate, the probability of facing a medical malpractice claim is high. Recent emphasis on tort reform within the political sphere has brought this issue to the forefront of medical literature. Despite the widespread fear of litigation in the medical community, few studies have provided an analysis of malpractice litigation in the field. ⋯ CONCLUSIONS Unlike other medical specialties, a majority of the verdicts were not in the defendant's favor. The mean payouts were nearly 5-fold less in cases in which a settlement was reached, as opposed to a summary judgment. Neurosurgeons accounted for a small percentage of all codefendants.

Expression profile of long noncoding RNAs in human cerebral aneurysms: a microarray analysis.
OBJECTIVE The pathogenesis of cerebral aneurysms (CAs) remains largely unknown. Long noncoding RNAs (lncRNAs) were reported recently to play crucial roles in many physiological and biological processes. Here, the authors compared the gene-expression profiles of CAs and their control arteries to investigate the potential functions of lncRNAs in the formation of CAs. ⋯ The results of further gene ontology and KEGG pathway analyses indicated that lncRNAs were involved mainly in regulating immune/inflammatory processes/pathways and vascular smooth muscle contraction, both of which are known to have crucial pathobiological relevance in terms of CA formation. CONCLUSIONS By comparing CAs with their control arteries, the authors created an expression profile of lncRNAs in CAs and propose here their possible roles in the pathogenesis of CAs. The results of this study provide novel insight into the mechanisms of CA pathogenesis and shed light on developing new therapeutic intervention for CAs in the future.

Algorithm for bionic hand reconstruction in patients with global brachial plexopathies.
OBJECTIVE Global brachial plexus lesions with multiple root avulsions are among the most severe nerve injuries, leading to lifelong disability. Fortunately, in most cases primary and secondary reconstructions provide a stable shoulder and restore sufficient arm function. Restoration of biological hand function, however, remains a reconstructive goal that is difficult to reach. ⋯ ARAT scores improved from 3.4 ± 4.3 to 25.4 ± 12.7 (p = 0.043; mean ± SD) and SHAP scores improved from 10.0 ± 1.6 to 55 ± 19.7 (p = 0.042). DASH scores decreased from 57.9 ± 20.6 to 32 ± 28.6 (p = 0.042), indicating decreased disability. CONCLUSIONS The authors present an algorithm for bionic reconstruction leading to useful hand function in patients who lack biological treatment alternatives for a stiff, functionless, and insensate hand resulting from global brachial plexopathies.
