Abstract
Although folic acid fortification and advances in prenatal repair have reduced Spina Bifida (SB) prevalence and the severity of comorbidities, individuals with SB remain at elevated risk for neurocognitive impairments that studies have shown can negatively impact, among other things, urological self-care. Identifying and addressing these impairments with practical interventions can meaningfully improve long-term outcomes for individuals with SB. We review neurocognitive impairments associated with SB and provide practical solutions to support improvement of long-term urological outcomes.

Abstract
There is paucity of evidence regarding relative performance of antibiotic-medicated (AM), silver-medicated (SM) and non-medicated (NM) ventricular catheters in controlling infection rate. We aim to quantitatively synthesize the current evidence after addition of the three-armed British Antibiotic and Silver Impregnated Catheters for ventriculoperitoneal Shunts (BASICS) trial, understand the need for further evidence using trial sequential analysis (TSA) and incorporate the indirect evidence using network meta-analysis (NMA). Randomized controlled trials (RCTs) comparing AM, SM and NM ventriculoperitoneal shunt (VPS) or external ventricular drain (EVD) were included. Antibiotic-medicated VPS show a significantly lower infection rate as compared to non-medicated VPS (RR 0.44; 95% CI: 0.27-0.73; p = 0.001), however, TSA reveals need for further evidence. SM including both EVD as well as VPS were found to be inferior to AM while no significant difference was found in comparison to the NM catheters. In NMA for VPS, the AM were found to be significantly better than SM (RR 0.41, 95% CI: 0.22-0.75) as well as NM (RR 0.42; 95% CI: 0.25-0.71) with a SUCRA of 99.8% and a mean rank of 1. However, antibiotic medicated shunts did not show a statistically significant association with reoperation rate (RR 0.99; 95% CI:0.81-1.20; p = 0.9) with no further need for evidence as per TSA.

Abstract
OBJECTIVE Lifespan outcomes of simultaneous versus sequential myelomeningocele repair and shunt placement or effects of repeated shunt revisions on specific domains of IQ or fine motor dexterity are largely unknown. The current study addressed these gaps in a large cohort of children and adults with spina bifida myelomeningocele (SBM). METHODS Participants between 7 and 44 years of age with SBM and shunted hydrocephalus were recruited from international clinics at two time points. Each participant completed a standardized neuropsychological evaluation that included estimates of IQ and fine motor dexterity. Simultaneous versus sequential surgical repair and number of shunt revisions were examined in relation to long-term IQ and fine motor scores. RESULTS Simultaneous myelomeningocele repair and shunting were associated with more frequent shunt revisions, as well as to lower Full Scale and verbal IQ scores, controlling for number of shunt revisions. More shunt revisions across study time points were associated with higher nonverbal IQ (NVIQ) scores. No effects were observed on fine motor dexterity. CONCLUSIONS Findings indicate generally greater influence of surgery type over shunt revision history on outcomes in well-managed hydrocephalus. Findings supported apparent, domain-specific benefits of sequential compared to simultaneous surgery across the lifespan in SBM. Higher NVIQ scores with greater number of additional shunt revisions across surgery type supported positive outcomes with effective surgical management for hydrocephalus.

Abstract
OBJECTIVE Predictors of permanent disability among individuals with spinal dysraphism are not well established. In this study, the authors examined potential risk factors for self-reported permanent disability among adults with spinal dysraphism. METHODS A total of 188 consecutive individuals undergoing follow-up in an adult spinal dysraphism clinic completed a standardized National Spina Bifida Patient Registry survey. Chi-square tests and logistic regression were used to assess bivariate relationships, while multivariate logistic regression was used to identify factors independently associated with self-identification as "permanently disabled." RESULTS A total of 106 (56.4%) adults with spina bifida identified themselves as permanently disabled. On multivariate analysis, relative to completion of primary and/or secondary school, completion of technical school (OR 0.01, 95% CI 0-0.40; p = 0.021), some college (OR 0.22, 95% CI 0.08-0.53; p < 0.001), college degree (OR 0.06, 95% CI 0.003-0.66; p = 0.019), and holding an advanced degree (OR 0.12, 95% CI 0.03-0.45; p = 0.002) were negatively associated with permanent disability. Relative to open myelomeningocele, diagnosis of closed spinal dysraphism was also negatively associated with permanent disability (OR 0.20, 95% CI 0.04-0.90; p = 0.036). Additionally, relative to no stool incontinence, stool incontinence occurring at least daily (OR 6.41, 95% CI 1.56-32.90; p = 0.009) or more than weekly (OR 3.43, 95% CI 1.10-11.89; p = 0.033) were both positively associated with permanent disability. There was a suggestion of a dose-response relationship with respect to the influence of educational achievement and frequency of stool incontinence on the likelihood of permanent disability. CONCLUSIONS The authors' findings suggest that level of education and degree of stool incontinence are the strongest predictors of permanent disability among adults with spinal dysraphism. These findings will be the basis of efforts to improve community engagement and to improve readiness for transition to adult care in a multidisciplinary pediatric spina bifida clinic.

Are Shunt Revisions Associated with IQ in Congenital Hydrocephalus? A Meta -Analysis. Neuropsychol Rev 2016; 26:329-339.

Abstract
Although it is generally acknowledged that shunt revisions are associated with reductions in cognitive functions in individuals with congenital hydrocephalus, the literature yields mixed results and is inconclusive. The current study used meta-analytic methods to empirically synthesize studies addressing the association of shunt revisions and IQ in individuals with congenital hydrocephalus. Six studies and three in-house datasets yielded 11 independent samples for meta-analysis. Groups representing lower and higher numbers of shunt revisions were coded to generate effect sizes for differences in IQ scores. Mean effect size across studies was statistically significant, but small (Hedges' g = 0.25, p < 0.001, 95 % CI [0.08, 0.43]) with more shunt revisions associated with lower IQ scores. Results show an association of lower IQ and more shunt revisions of about 3 IQ points, a small effect, but within the error of measurement associated with IQ tests. Although clinical significance of this effect is not clear, results suggest that repeated shunt revisions because of shunt failure is associated with a reduction in cognitive functions.

Abstract
OBJECT No previous reports exist that have evaluated the relationships of white matter (WM) integrity with the number of shunt revisions, ventricular volume after shunting, and cognition in medically stable children who have spina bifida and hydrocephalus (SBH). The authors hypothesized that enlarged ventricles and a greater number of shunt revisions decrease WM integrity in children. METHODS In total, 80 children (mean age 13.7 years) who had SBH underwent MRI and IQ testing. Probabilistic diffusion tractography was performed to determine mean diffusion tensor imaging (DTI) metrics along the frontal and parietal tectocortical pathways. The DTI metrics were evaluated for significant correlation with a composite IQ measure and with the total number of shunt revisions and the total lateral ventricular volume obtained through semiautomated parcellation of T1-weighted MRI scans. RESULTS An enlargement in total lateral ventricle volume and an increase in the number of shunt revisions were both associated with higher fractional anisotropy (FA) and with lower radial diffusivity (RD) along both frontal and parietal tectocortical pathways. Children who had not undergone a shunt revision had on average a greater lateral ventricle volume and higher FA and lower RD along frontal and parietal pathways than those who had undergone multiple shunt revisions. The mean DTI metrics along parietal pathways predicted IQ scores, but intellectual ability was not significantly correlated with ventricular volume or with the number of lifetime shunt revisions. CONCLUSIONS Significant changes in DTI metrics were observed as a function of ventricular volume. An increased lateral ventricle volume was associated with elevated FA and decreased RD. Given that the participants were medically stable at the time of the MRI examination, the results suggested that those who have enlarged ventricles show a DTI pattern consistent with axonal compression due to increased intracranial pressure (ICP) in attenuated hydrocephalus. Although limited by a cross-sectional design, the study's findings suggest that DTI metrics may serve as sensitive indicators for chronic, mild hydrocephalus in the absence of overt clinical symptoms due to increased ICP. Having enlarged ventricles and undergoing multiple shunt revisions did not affect intellectual ability in children with SBH.

Abstract
BACKGROUND A phase II trial of conformal radiotherapy (CRT) for pediatric high-grade glioma (HGG) was performed to evaluate disease control and late effects. METHODS Between July 1997 and January 2003, 34 pediatric patients (median age, 13.2 ± 6.7 years) with HGG were enrolled on an International Commission on Radiation Units and Measurements Report 50-compliant prospective trial using CRT with a 2 cm clinical target volume margin. Baseline and serial evaluations were performed to assess functional outcomes. RESULTS Median follow-up for the entire group was 18 months (range, 2-134 months). Twenty (58.8%) patients developed local progression, and 6 (17.6%) patients developed distant progression. Progression-free and overall survival at 10 years were 18.8% ± 6.9% and 16.8% ± 6.5%, respectively. At baseline, 40% of patients evaluated for intelligence quotient (IQ) scored below 85. Measures of cognitive function obtained during the first 12 months fit a mixed model with a quadratic function. The relationship between IQ and time was -1.1883 points/month for the linear term and 0.07728 points/month for the quadratic term (P = .0454). IQ decreased between baseline and 6 months and then increased slightly through 12 months. The opposite was found for (all P values of the quadratic term) activities of daily living (P = .0155), socialization (P = .0049), and the composite score (P = .0257) of adaptive behavior. CONCLUSION CRT using a 2 cm clinical target volume margin in pediatric HGG demonstrated tumor control comparable to conventional radiation therapy. Disrupted cognitive and adaptive behavioral functioning were present at baseline and throughout the course of disease.

Abstract
AbstractBackground: Cognitive dysfunction is a common complaint associated with obstructive hydrocephalus. The purpose of this study was to determine the effect of endoscopic third ventriculostomy (ETV) on the neuropsychological outcome in patients presenting with cognitive decline and obstructive hydrocephalus. Methods: A retrospective review of patients who underwent ETV at the University of Calgary and had both pre and post operative neuropsychological testing, was completed. Presenting clinical features, etiology of hydrocephalus and ventricle size utilizing frontal occipital horn ratio was obtained. Outcomes and complications of the ETV were recorded. Detailed measures of intelligence, attention and concentration, executive function, visual and verbal memory, language functions and fine motor skills were completed. Post treatment change was determined utilizing Reliable Change Index. Results: A total of 13 patients were identified. Etiology of the hydrocephalus was aqueductal stenosis in 8 and tectal glioma in 4. The majority of patients (11 of 13, 85%) demonstrated cognitive dysfunction at the borderline (≤1 SD) or impairment level (≤1.5 SDs) in at least one domain. Nine patients (69%) showed reliable improvement in at least one cognitive domain. The greatest improvement was seen with visual memory (42%). One quarter to one third of patients demonstrated improvement on tests of intelligence quotient, verbal memory, attention and concentration, and executive function. Two patients declined in executive functioning. Ventricle size improved in eight patients. Conclusions: ETV is a safe effective procedure, capable of producing reliable improvements in cognitive dysfunction with hydrocephalus. Patients with cognitive complaints alone may benefit from ETV.

Abstract
OBJECT The objective of this investigation was to review the clinical characteristics of recurrent CSF shunt infections in a large pediatric neurosurgical practice and to assess the safety and efficacy of reusing original ventricular entry sites for external ventricular drainage during treatment of infections and for subsequent reinsertion of shunts. METHODS Prospectively accrued clinical data on all patients treated at Children's Hospital Colorado for CSF shunt infections within a 10.5-year span were retrospectively investigated. RESULTS One hundred twenty-one consecutive cases of CSF shunt infection met inclusion criteria. Recurrent shunt infection attributable to the management of these infections occurred in 14 cases (11.6%). Three recurrent infections were with their original organisms, 7 were organisms different from the original organisms, and 4 were indeterminate. CONCLUSIONS Half or more of recurrent shunt infections were with organisms different from the original organism, and hence were new-type infections introduced during the management of the original infections. Incomplete eradication of original pathogens accounted for 3 (21.4%) of the 14 recurrent infections. Reusing recently infected or contaminated ventricular entry sites, both for CSF drainage during treatment and for implantation of new shunts, was as safe, with regard to risk of recurrent infection, as switching to new entry sites. Prior evidence of shunt infection is not, alone, a sufficient reason to change to a previously well-functioning site, and reuse of contaminated ventricular entry sites avoids all risks associated with making new ventricular entries.

Abstract
INTRODUCTION Individuals with neurodevelopmental disorders have been observed to show accelerated cognitive aging or even dementia as early as 30 and 40 years of age. Memory deficits are an important component of age-related cognitive loss. METHODS In this study, we investigated prospective memory, which is often impaired in aging, in a group of 32 adults with spina bifida meningomyelocele (SBM), including members of the oldest living cohort successfully treated with shunts to divert excess cerebrospinal fluid, ventriculomegaly, and hydrocephalus, who are now around 50 years of age. Seventeen typically developing adults provided a comparison group. RESULTS The SBM and comparison groups differed in the prospective memory total score as well as in both time-based and event-based subscores. Prospective memory was impaired in both older and younger individuals with SBM. However, the percentage of individuals with impaired or poor prospective memory was three times higher in the older SBM group than in the younger SBM group. The results are considered in relation to specific features of the complex brain reorganization in SBM.

Abstract
OBJECT The safety of reusing ventricular drain sites for shunting CSF in patients with no history of infection involving either the ventricular drain or the CSF was the focus of this investigation. METHODS Prospectively accrued clinical data on all patients who, in an 8-year span ending in June 2008, underwent external ventricular drain placement and subsequently required CSF shunts were retrospectively evaluated for evidence of shunt infection and other complications. RESULTS The infection rate for 50 consecutive operations in 50 patients who met the inclusion criteria was 2.0%. CONCLUSIONS Data from this study support the position that the reuse of ventriculostomy tracts when implanting first-time CSF shunts is, with regard to the risk of infection, a safe practice and avoids all risks associated with making a new ventricular entry.

Abstract
AIMS To explore learning, memory and executive abilities in children with hydrocephalus without learning disabilities, and to find out whether children with an isolated hydrocephalus differed from those with hydrocephalus in combination with myelomeningocele (MMC). METHODS Thirty-six children with an intelligence quotient (IQ) of >or=70 from a population of all the 107 children with hydrocephalus born in western Sweden in 1989-1993 were examined and compared with age- and gender-matched controls. The neuropsychological assessment of the school-aged child (NIMES) test battery was used. RESULTS The children with hydrocephalus differed significantly from controls in all functions apart from registration skills and recognition. Learning, memory and executive functions were all impaired. Twenty children with infantile hydrocephalus did not differ from those with hydrocephalus associated with MMC. Also, children with an IQ of >84 performed significantly worse than controls. CONCLUSIONS Despite an IQ of >or=70, children with hydrocephalus had significantly impaired learning, memory and executive functions. When major brain lesions resulting in learning disability had been excluded, the hydrocephalus, rather than the underlying aetiology, was most important for the development of cognitive functions.

Abstract
OBJECT Meningomyelocele (MMC) is a common central nervous system birth defect. As one of many problems facing patients with MMC, learning disabilities are often overlooked. The aim of this study was to evaluate IQs in a group of children with MMCs and determine if a correlation exists between intelligence level and the presence of an MMC and/or its complications. METHODS A case-control study was conducted at the Children's Hospital Medical Center in Tehran, Iran, from December 2004 through December 2005. The patient group included 50 children with MMC from 5 to 12 years of age who were referred to the authors' institution for treatment of complications or for follow up after surgery for MMC closure. The patient group was individually matched for age and sex with a control group of 50 children referred to the hospital for other reasons and who did not have MMC or other neurological abnormalities. The IQs in all children in this study were evaluated using the Ravens Progressive Matrices test. The children in both groups were similar in the socioeconomic status of the family (p = 0.347) and educational status of the father (p = 0.117) and mother (p = 0.439). Patient age at the time of surgery for MMC closure varied from 1 day to 96 months (mean 4.1 months). Only 20% of the patients with MMC could walk with a normal gait. Forty-six percent of the patients had undergone placement of a ventriculoperitoneal shunt, and half of these patients experienced shunt-related complications; 72% of the children in the patient group were completely incontinent for both urine and feces. The IQ results obtained in the patient group ranged from 73 to 134 with a mean (+/- standard deviation) of 96.62 +/- 13.01. In the control group the IQ range was 70 to 128, and the mean was 104.82 +/- 12.30. Compared with the control group there was a statistically significant correlation between having an MMC and having a lower IQ (p < 0.001, paired t-test). CONCLUSIONS Although the average IQ in the patient group was significantly lower than that in the control group, it is important to note that all children in the patient group had an average or above-average IQ. In contrast with the results reported in other studies, earlier repair of the MMC, the presence of a shunt or shunt-related complications, walking difficulty, and the spinal level of the lesion did not correlate significantly with IQs. Therefore, the lower IQ and reduced cognitive levels noted in these patients result from the disease process itself and not from the associated complications.

Abstract
INTRODUCTION Few series compare endoscopic third ventriculostomies (ETV) and ventriculoperitoneal shunts (VPS). To avoid the complications after a shunt insertion, there is an increased tendency to perform a third ventriculostomy. We reviewed all pediatric patients operated in the French-speaking part of Switzerland for a newly diagnosed obstructive hydrocephalus since 1992 and compared the outcome of patients who benefited from ETV to the outcome of patients who benefited from VPS. There were 24 ETV and 31 VPS. DISCUSSION At 5 years of follow-up, the failure rate of ETV was 26%, as compared to 42% for the VPS group. This trend is also found in the pediatric series published since 1990 (27 peer-reviewed articles analyzed). CONCLUSION In accordance to this trend, although a statistical difference cannot be assessed, we believe that ETV should be the procedure of choice in pediatric obstructive hydrocephalus.

Abstract
The consequences of congenital brain disorders for adult cognitive function are poorly understood. We studied different forms of memory in 29 young adults with spina bifida meningomyelocele (SBM), a common and severely disabling neural tube defect. Nondeclarative and semantic memory functions were intact. Working memory was intact with low maintenance and manipulation requirements, but impaired on tasks demanding high information maintenance or manipulation load. Prospective memory for intentions to be executed in the future was impaired. Immediate and delayed episodic memory were poor. Memory deficits were exacerbated by an increased number of lifetime shunt revisions, a marker for unstable hydrocephalus. Memory status was positively correlated with functional independence, an important component of quality of life.

Abstract
PURPOSE To prospectively assess the impact of conformal radiation therapy (CRT) and demographic and clinical variables on four measures of attention in pediatric and young adult patients with localized primary brain tumors. PATIENTS AND METHODS We prospectively evaluated 120 patients with primary brain tumors, ages 2 to 24.4 years (median, 9.2 years). Evaluations were done using the computerized Conners' Continuous Performance Test (CCPT). We analyzed errors of omission (inattentiveness), errors of commission (impulsivity), reaction time, and an overall index of performance before CRT, weekly during CRT, and serially up to 60 months after the start of CRT. RESULTS Before CRT, patients exhibited mild inattentiveness. During CRT, impulsivity decreased significantly (P = .002). After CRT, inattentiveness increased significantly (P = .03), and global attention disorders were associated with craniopharyngioma (P < .0001), supratentorial tumors (P = .008), optic pathway and diencephalic tumors (P = .012), and subtotal resection of the tumor (P = .010). CONCLUSION Brain tumors and their treatment impair sustained attention and reaction time. A decline in impulsivity and relative stability of the other CCPT scores over the course of CRT demonstrated the absence of early radiation-related cognitive sequelae. Local tumor effects, initial surgical intervention, and focal irradiation of central structures contribute to long-lasting attentional problems in pediatric and young adult patients.
