A hospital-based analysis of pseudomeningoceles after elective craniotomy in children: what predicts need for intervention?

OBJECTIVE: In pediatric patients, the development of a postoperative pseudomeningocele after an elective craniotomy is not unusual. Most will resolve with time, but some may require intervention. In this study, the authors analyzed patients who required intervention for a postoperative pseudomeningocele following an elective craniotomy or craniectomy and identified factors associated with the need for intervention. METHODS: An institutional operative database of elective craniotomies and craniectomies was queried to identify all surgeries associated with development of a postoperative pseudomeningocele from January 1, 2010, to December 31, 2017. Demographic and surgical data were collected, as were details regarding postoperative events and interventions during either the initial admission or upon readmission. A bivariate analysis was performed to compare patients who underwent observation with those who required intervention. RESULTS: Following 1648 elective craniotomies or craniectomies, 84 (5.1%) clinically significant pseudomeningoceles were identified in 82 unique patients. Of these, 58 (69%) of the pseudomeningoceles were diagnosed during the index admission (8 of which persisted and resulted in readmission), and 26 (31%) were diagnosed upon readmission. Forty-nine patients (59.8% of those with a pseudomeningocele) required one or more interventions, such as lumbar puncture(s), lumbar drain placement, wound exploration, or shunt placement or revision. Only race (p < 0.01) and duraplasty (p = 0.03, OR 3.0) were associated with the need for pseudomeningocele treatment. CONCLUSIONS: Clinically relevant pseudomeningoceles developed in 5% of patients undergoing an elective craniotomy, with 60% of these pseudomeningoceles needing some form of intervention. The need for intervention was associated with race and whether a duraplasty was performed.

Shunt Failure-The First 30 Days.

BACKGROUND: Incontrovertible predictors of shunt malfunction remain elusive. OBJECTIVE: To determine predictors of shunt failure within 30 d of index surgery. METHODS: This was a single-center retrospective cohort study from January 2010 through November 2016. Using a ventricular shunt surgery research database, clinical and procedural variables were procured. An "index surgery" was defined as implantation of a new shunt or revision or augmentation of an existing shunt system. The primary outcome was shunt failure of any kind within the first 30 days of index surgery. Bivariate models were created, followed by a final multivariable logistic regression model using a backward-forward selection procedure. RESULTS: Our dataset contained 655 unique patients with a total of 1206 operations. The median age for the cohort at the time of first shunt surgery was 4.6 yr (range, 0-28; first and third quartile, .37 and 11.8, respectively). The 30-day failure rates were 12.4% when analyzing the first-index operation only (81/655), and 15.7% when analyzing all-index operations (189/1206). Small or slit ventricles at the time of index surgery and prior ventricular shunt operations were found to be significant covariates in both the "first-index" (P < .01 and P = .05, respectively) and "all-index" (P = .02 and P < .01, respectively) multivariable models. Intraventricular hemorrhage at the time of index surgery was an additional predictor in the all-index model (P = .01). CONCLUSION: This study demonstrates that only 3 variables are predictive of 30-day shunt failure when following established variable selection procedures, 2 of which are potentially under direct control of the surgeon.

How Does the Media Portray Neurosurgeons?

BACKGROUND: It is not unusual to find neurosurgeons in the news and entertainment. The present study examined the portrayal of neurosurgeons by major print and online media sources. METHODS: Two search strategies identified articles from October 1, 2012 to October 1, 2017 containing the keyword "neurosurgeon." The top 25 newspapers in the United States, determined by their circulation, were searched using the LexisNexis Academic or NewsBank databases; a layman's Google News search was used to collect online stories. Each identified article was evaluated to confirm the relevance and then examined for content. Relevant characteristics for each article and neurosurgeon were determined and analyzed. RESULTS: Our searches returned 1005 articles comprising 561 unique stories about 203 different neurosurgeons. One particular neurosurgeon had 459 reports (45.7%). More articles were reported in 2015 (405; 40.3%) than any other single year. Most articles featured male neurosurgeons (879; 87.1%) and neurosurgeons who had been practicing for >20 years (636; 63.0%), with just 10 institutions accounting for the training of most of them (733; 72.6%). The articles were classified as positive (270; 26.9%), negative (356; 35.4%), or neutral (379; 37.7%) in terms of their reflection on the field of neurosurgery. The odds of a negative story were greater for male neurosurgeons, within 10 years of residency completion, and in a nonacademic position. CONCLUSIONS: Neurosurgeons are naturally subject to media coverage, and we must be cognizant that this predilection can serve as both an occupational advantage and an occupational hazard.

An Analysis of Publication Productivity During Residency for 1506 Neurosurgical Residents and 117 Residency Departments in North America.

BACKGROUND: Bibliometrics is defined as the study of statistical and mathematical methods used to quantitatively analyze scientific literature. The application of bibliometrics in neurosurgery continues to evolve. OBJECTIVE: To calculate a number of publication productivity measures for almost all neurosurgical residents and departments within North America. These measures were correlated with survey results on the educational environment within residency programs. METHODS: During May to June 2017, data were collected from departmental websites and Scopus to compose a bibliometric database of neurosurgical residents and residency programs. Data related to authorship value and study content were collected on all articles published by residents. A survey of residency program research and educational environment was administered to program directors and coordinators; results were compared with resident academic productivity. RESULTS: The median number of publications in residency was 3; median h-index and Resident index were 1 and 0.17 during residency, respectively. There was a statistically significant difference in academic productivity among male neurosurgical residents compared with females. The majority of articles published were tier 1 clinical articles. Residency program research support was significantly associated with increased resident productivity (P < .001). Scholarly activity requirements were not associated with increased resident academic productivity. CONCLUSION: This study represents the most comprehensive bibliometric assessment of neurosurgical resident academic productivity during training to date. New benchmarks for individual and department academic productivity are provided. A supportive research environment for neurosurgical residents is associated with increased academic productivity, but a scholarly activity requirement was, surprisingly, not shown to have a positive effect.
