Understanding factors influencing primary treatment with intradetrusor onabotulinumtoxinA versus augmentation cystoplasty in patients with spina bifida.

PURPOSE: Surgical interventions in the urologic management of children with neurogenic bladder secondary to spina bifida aim to preserve upper tract function, prevent urinary tract infections, and optimize quality of life. However, since the introduction of intravesical onabotulinumtoxinA (Botox) in the management of these patients, the indications for choosing Botox over augmentation cystoplasty (AC) remain undefined. The objective of this study was to determine which factors lead patients to undergo Botox versus AC as a primary surgical treatment after failing medical management. METHODS: We retrospectively reviewed the records of pediatric patients with myelomeningocele undergoing either primary Botox or primary AC at our institution between 2013 and 2018. We recorded demographic and clinical information. We identified 10 important clinical decision-making factors: bladder trabeculation, vesicoureteral reflux, or hydronephrosis on imaging; end-filling pressure (EFP) ≥40 cm H2O, detrusor overactivity, detrusor-sphincter dyssynergia, or reduced capacity on urodynamic studies; physician-perceived bladder hostility; and patient/family desire for continence and independence. The presence of these factors was compared between patients undergoing either primary Botox or primary AC. RESULTS: We identified 14 and 50 myelomeningocele patients who underwent primary AC and primary Botox, respectively. We found no significant differences in age, sex, race, or history of reconstructive surgery (antegrade continence enema or catheterizable channel). For the 10 decision-making factors, desire for independence/continence (p = <0.001) and reduced capacity (p = 0.002) were significantly associated with AC, while trabeculation (p = 0.006), EFP ≥40 cm H2O (p = 0.029), rising slope (p = 0.019), and physician-perceived hostility (p = 0.012) were significantly more common with Botox. CONCLUSIONS: At our institution, quality of life measures prompted AC over objective urodynamic or imaging findings before attempting Botox. These findings support a shared decision-making approach when considering surgical intervention for neurogenic bladder secondary to myelomeningocele.

Association between gestational phthalate exposure and newborn head circumference; impacts by race and sex.

Observational and experimental studies report associations between gestational phthalate exposure and fetal development, yet few data exist to characterize phthalate effects on head circumference (HC) or to estimate the impact of race or sex. To address this data gap, we enrolled 152 African American and 158 white mothers with uncomplicated singleton pregnancies from the Charleston, South Carolina (USA) metropolitan area in a prospective birth cohort. Study participants provided up to two urine specimens during mid and late gestation, completed a study questionnaire, and allowed access to hospital birth records. We measured eight phthalate monoester metabolites using liquid chromatography with tandem mass spectrometry, and calculated molar sums of phthalate parent diesters. After specific gravity correction, we tested for associations between phthalates and neonatal HC (cm) and cephalization index (cm/g) using multiple informant linear regression with inverse probability weighting to account for selection bias between repeated urine sampling, adjusted for maternal race, age, body mass index, education, and smoking. We explored interactions by maternal race and infant sex. A doubling of urinary monoethyl phthalate (MEP) concentration was associated with a -0.49% (95%CI: -0.95%, -0.02%) smaller head circumference, although seven other phthalate metabolites were null. There were no statistically significant associations with cephalization index. HC was larger for whites than African American newborns (p < 0.0001) but similar for males and females (p = 0.16). We detected interactions for maternal race with urinary monobutyl phthalate (MBP; p = 0.03), monobenzyl phthalate (MBzP; p = 0.01), monoethylhexyl phthalate (MEHP; p = 0.05), monomethyl phthalate (MMP; p = 0.02), and the sum of dibutyl phthalate metabolites (∑DBP; p = 0.05), in which reduced HC circumference associations were stronger among whites than African Americans, and interactions for sex with MBP (p = 0.08) and MiBP (p = 0.03), in which associations were stronger for females than males. Our results suggest that gestational phthalate exposure is associated with smaller neonatal HC and that white mothers and female newborns have greater susceptibility.

Effect of Prenatal Repair of Myelomeningocele on Urological Outcomes at School Age.

PURPOSE: We investigated longer term urological outcomes in patients enrolled in the Management of Myelomeningocele Study (MOMS). MATERIALS AND METHODS: Women who participated in the original trial were asked for consent for followup for their child at age 6 years or older in a single comprehensive study visit to a MOMS center. Participating children underwent urological and radiologic procedures to provide objective evidence of current bladder functioning. Primary urological outcome was defined as any among need for clean intermittent catheterization, vesicostomy, urethral dilatation or augmentation cystoplasty. RESULTS: A total of 156 children were evaluated, with a mean age of 7.4 years. Overall 62% vs 87% in the prenatal and postnatal surgery groups, respectively, were placed on clean intermittent catheterization (RR 0.71, 95% CI 0.58-0.86, p <0.001). Voiding status was significantly different between the groups (p <0.001) as 24% in the prenatal group vs 4% in the postnatal group (RR 5.8, 95% CI 1.8-18.7) were reported to be voiding volitionally. Augmentation cystoplasty, vesicostomy and urethral dilation did not differ between the 2 groups. Aside from a larger post-void residual urodynamic catheterization volume, there were no other statistical differences in videourodynamic data or findings on renal/bladder ultrasound. CONCLUSIONS: Prenatal closure of myelomeningocele resulted in less reported clean intermittent catheterization at school age and the mechanism for this is unclear. Although most children are in diapers or on clean intermittent catheterization, parental reports showed children who underwent prenatal closure may be more likely to void volitionally than the postnatal group. Despite these findings, urological outcomes alone should not be the sole impetus to perform in utero closure in children with spina bifida.

Pelvic floor biofeedback therapy in children: Assessment of symptom scores in responders and non-responders.

INTRODUCTION: Pelvic Floor Biofeedback Therapy (PFBT) can be an effective treatment for pediatric lower urinary tract symptoms (LUTS). Due to differing perceptions of efficacy and practice patterns, we sought to further evaluate PFBT in our practice. We hypothesized that PFBT results in quiescence of EMG activity during voiding and improves questionnaire scores in patients with LUTS. METHODS: We retrospectively reviewed all patients undergoing PFBT and refined the analysis to females ≥6 years old with ≥2 sessions with completed voiding questionnaires pre- and post-treatment, active EMG during voiding, with non-neurogenic urinary tract complaints refractory to standard urotherapy. Validated Bladder Bowel Dysfunction (BBD) questionnaires were collected at each visit. Quiescence of EMG activity and changes in BBD score were the primary outcomes. RESULTS: 229 patients underwent ≥1 PFBT session, of which 64 females ≥6 years of age with ≥2 PFBT sessions and completed pre and post PFBT voiding questionnaires were identified. In this group, mean age at PFBT start was 10.1 (6.2-17.0). Patients completed 3.1 sessions (2-6). No difference was seen in post-void residual (PVR) between first and last session (23.8 vs 22.6 mL, P = 0.55). Median questionnaire score decreased from 18 (4-42) before to 13 (2-28) following PFBT (P < 0.0001). Responders, characterized by silencing of the EMG after PFBT, occurred in 31% (20/64). Non-responders were younger (P = 0.007) with higher pre-PFBT questionnaire scores. CONCLUSION: The use of PFBT appears to result in a significant reduction in symptom scores, though quiescence of EMG was observed following therapy in less than 1/3 of patients.

In utero effects of maternal phthalate exposure on male genital development.

BACKGROUND: Phthalates are used extensively in commercial and personal care products and maternal exposure is ubiquitous. Phthalates are anti-androgenic, but the potential effects of phthalates on male penile development have not been assessed in utero. OBJECTIVE: The study aims to investigate the association between early pregnancy phthalate exposure and fetal penile development, overall and by race. METHODS: Prospective cohort study of women with singleton pregnancies presenting for prenatal ultrasound between 18 and 22 weeks' gestation. Maternal urine samples were assayed for eight phthalate monoester metabolites. We used maternal phthalate levels at 18 to 22 weeks' gestation as predictors of fetal size using multiple linear regression models, adjusted for fetal gestational age, maternal age, race, smoking, and education. We incorporated a phthalate by race interaction into a second set of regression models. RESULTS: We detected statistically significant race interactions for continuous phthalates with penile width. Race interactions were also suggested for penile length and volume using tertiles of phthalates with point estimates generally positive for whites and negative for African Americans. CONCLUSION: Penile development is significantly influenced by race, and the impact of maternal phthalates on penile measurements also varies by race. Maternal phthalate exposure can adversely affect in utero penile growth and development, especially among African Americans.

Prevalence of Eight Phthalate Monoesters in Water from the Okavango Delta, Northern Botswana.

Phthalate diesters are used in personal care products, plastics, and pesticides, resulting in widespread human and wildlife exposure. Phthalate diesters leach out of these products and ultimately enter biological systems where they are quickly metabolized to phthalate monoesters and glucuronides. As such, phthalate monoesters can serve as indicators of anthropogenic activity in wilderness areas. The Okavango Delta, an inland seasonal wetland covering 5000-12,000 km2 in Botswana, provides fresh water to many species of birds, fish, reptiles, and large mammals. Water samples (N = 46) were taken from across the Okavango water system, extracted, and analyzed for eight different phthalate monoesters using liquid chromatography and isotope dilution mass spectrometry. Seven of eight phthalate monoesters were detected from the low ng/L to low µg/L levels. Phthalate monoesters were found in samples from all five sampling regions. Sources of these contaminants are unknown, but their presence indicates encroachment of human activity on the Okavango Delta.

Interrater Reliability in Interpretation of Neuropathic Pediatric Urodynamic Tracings: An Expanded Multicenter Study.

PURPOSE: Urodynamic findings often guide treatment for neuropathic bladder and are reported as objective data points in multi-institutional trials. However, urodynamic interpretation can be variable. In a pilot study pediatric urologists interpreting videourodynamics exhibited only moderate agreement despite similar training and practice patterns. We hypothesized the pilot study variability would be replicated in a multi-institutional study. MATERIALS AND METHODS: We developed an anonymous electronic survey that contained 20 scenarios, each with a brief patient history, 1 urodynamic tracing and fluoroscopic imagery. All videourodynamics were completed during routine care of patients with neuropathic bladder at a single institution. Pediatric urologists from Centers for Disease Control and Prevention Urologic Protocol sites were invited to complete an interpretation instrument for each scenario. Fleiss kappa and 95% confidence limits were reported, with Fleiss kappa 1.00 corresponding to perfect agreement. RESULTS: The survey was completed by 14 pediatric urologists at 7 institutions. Substantial agreement was seen for assessment of fluoroscopic bladder shape (Fleiss kappa 0.73), while moderate agreement was observed for assessment of bladder safety, end filling detrusor pressure and bladder capacity (Fleiss kappa 0.50, 0.56 and 0.54, respectively). Fair agreement was seen for electromyographic synergy and presence of detrusor overactivity (Fleiss kappa 0.21 and 0.35, respectively). CONCLUSIONS: Experienced pediatric urologists demonstrate variability during interpretation of videourodynamic tracings. Subjectivity of assessment of electromyographic activity and detrusor overactivity was confirmed in this expanded study. Future work to improve the reliability of videourodynamic interpretation would improve the quality of clinical care and the quality of multi-institutional studies that use urodynamic data points as outcomes.

The Management of Myelomeningocele Study: full cohort 30-month pediatric outcomes.

BACKGROUND: Previous reports from the Management of Myelomeningocele Study demonstrated that prenatal repair of myelomeningocele reduces hindbrain herniation and the need for cerebrospinal fluid shunting, and improves motor function in children with myelomeningocele. The trial was stopped for efficacy after 183 patients were randomized, but 30-month outcomes were only available at the time of initial publication in 134 mother-child dyads. Data from the complete cohort for the 30-month outcomes are presented here. Maternal and 12-month neurodevelopmental outcomes for the full cohort were reported previously. OBJECTIVE: The purpose of this study is to report the 30-month outcomes for the full cohort of patients randomized to either prenatal or postnatal repair of myelomeningocele in the original Management of Myelomeningocele Study. STUDY DESIGN: Eligible women were randomly assigned to undergo standard postnatal repair or prenatal repair <26 weeks gestation. We evaluated a composite of mental development and motor function outcome at 30 months for all enrolled patients as well as independent ambulation and the Bayley Scales of Infant Development, Second Edition. We assessed whether there was a differential effect of prenatal surgery in subgroups defined by: fetal leg movements, ventricle size, presence of hindbrain herniation, gender, and location of the myelomeningocele lesion. Within the prenatal surgery group only, we evaluated these and other baseline parameters as predictors of 30-month motor and cognitive outcomes. We evaluated whether presence or absence of a shunt at 1 year was associated with 30-month motor outcomes. RESULTS: The data for the full cohort of 183 patients corroborate the original findings of Management of Myelomeningocele Study, confirming that prenatal repair improves the primary outcome composite score of mental development and motor function (199.4 ± 80.5 vs 166.7 ± 76.7, P = .004). Prenatal surgery also resulted in improvement in the secondary outcomes of independent ambulation (44.8% vs 23.9%, P = .004), WeeFIM self-care score (20.8 vs 19.0, P = .006), functional level at least 2 better than anatomic level (26.4% vs 11.4%, P = .02), and mean Bayley Scales of Infant Development, Second Edition, psychomotor development index (17.3% vs 15.1%, P = .03), but does not affect cognitive development at 30 months. On subgroup analysis, there was a nominally significant interaction between gender and surgery, with boys demonstrating better improvement in functional level and psychomotor development index. For patients receiving prenatal surgery, the presence of in utero ankle, knee, and hip movement, absence of a sac over the lesion and a myelomeningocele lesion of ≤L3 were significantly associated with independent ambulation. Postnatal motor function showed no correlation with either prenatal ventricular size or postnatal shunt placement. CONCLUSION: The full cohort data of 30-month cognitive development and motor function outcomes validate in utero surgical repair as an effective treatment for fetuses with myelomeningocele. Current data suggest that outcomes related to the need for shunting should be counseled separately from the outcomes related to distal neurologic functioning.

Current State of Fetal Intervention for Lower Urinary Tract Obstruction.

PURPOSE OF THE REVIEW: In this article, we explore the origins of intervention of fetal lower urinary tract obstruction, and we specifically discuss the background and recent outcomes of vesicoamniotic shunt placement and fetal cystoscopy. The article seeks to provide a comprehensive overview of the field while bringing the reader quickly up to speed on the pertinent literature and the critical data that are available to guide decision-making regarding intervention. RECENT FINDINGS: Appropriate patient selection for fetal intervention remains challenging despite advances in prenatal imaging. Both a randomized controlled trial and multiple systematic reviews show evidence of a perinatal survival benefit following fetal intervention but rates of renal morbidity remain very high. Despite 30 years of research, fetal lower urinary tract obstruction remains a difficulty entity to treat. Intervention may lead to survival, but physicians and caregivers must remain alert for the distinct possibility of long-term renal morbidity in survivors.

Update on Continent Catheterizable Channels and the Timing of their Complications.

PURPOSE: We previously reported catheterizable channel associated outcomes and concluded that the incidence of postoperative complications was greatest in the first 2 years after surgery. At that time our followup was short. In this series we sought to determine whether complications continued to accumulate with longer followup in an updated cohort of patients. MATERIALS AND METHODS: We comprehensively reviewed the outcomes in 81 consecutive patients who underwent construction of a MACE (Malone antegrade continence enema) and/or a Mitrofanoff channel in association with complex genitourinary reconstruction. Mean followup was 80.1 months. Outcomes of these 119 stomas were classified by Clavien-Dindo grade and time to complication. RESULTS: The 48 unique, channel related events (40.3%) necessitated a total of 70 interventions with a mean 24.2 months to the first event. Difficult catheterization was the most common event, occurring in 20.1% of channels an average of 29.9 months after surgery. Stomal stenosis was also common, developing in 12.6% of channels at an average of 19.9 months after surgery. Unique complications clustered in the first 2 years, after which there was a statistically significant decline (p = 0.0013). High grade complications similarly clustered (p <0.0001). Channel composition was significantly associated with rates of difficult catheterization events. CONCLUSIONS: Compared to our previous cohort of patients with similar volume but shorter followup, our assumption that channel associated complications cluster postoperatively and then decrease significantly was correct. Our current and more detailed series demonstrates that the rate of postoperative complications decreases with time. However, with longer followup patients continue to experience lower grade events requiring fewer interventions.

Interrater Reliability in Pediatric Urodynamic Tracings: A Pilot Study.

PURPOSE: Urodynamic studies are crucial to neuropathic bladder management and they often determine surgical intervention. However, current evidence indicates that interpretations show poor agreement across physicians. We sought to determine the interrater reliability of urodynamic interpretation in our practice. We hypothesized that there would be strong correlation among pediatric urologists of similar training in a single academic practice. MATERIALS AND METHODS: We retrospectively identified patients with neuropathic bladder who underwent urodynamics at our institution between 2014 and 2015. An anonymous electronic survey (phase I) was developed with 20 clinical scenarios, each containing a brief history, a single urodynamic tracing and an accompanying fluoroscopic image. Faculty members assessed each tracing by an online instrument developed using urodynamic reports and published literature. The primary outcome was statistical correlation across raters as measured by the Spearman correlation coefficient. In a followup study (phase II) we investigated the sources of variability in urodynamic interpretations. RESULTS: Six faculty members completed the study with a response rate of 100%. In comparing urodynamic interpretation across raters, the faculty demonstrated a weak to strong correlation (rs 0.39-0.61, p <0.001). A strong correlation was found for fluoroscopic and clinical decision making variables, while electromyography synergy and detrusor overactivity demonstrated weaker correlation across physicians. CONCLUSIONS: Faculty interpretations of urodynamic tracings showed only moderate agreement despite a close working relationship and similar training at a single institution. Variability in interpretation can strongly impact patient treatment. Therefore, further work is needed to standardize the reporting and interpretation of urodynamic studies to optimize patient care.

Modulation of the rat micturition reflex with transcutaneous ultrasound.

INTRODUCTION: Low intensity focused ultrasound has recently been identified as a novel method of stimulating targeted neurons. We hypothesized that ultrasound stimulation of the posterior tibial nerve would inhibit bladder contractions in an established rat model of rhythmic bladder contractions. METHODS: Cyclical detrusor contractions were initiated by placing a transurethral catheter in female rats and infusing saline into the bladder. Transcutaneous ultrasound pulses were then delivered to the lower extremity of a rat (overlying the posterior tibial nerve) using a single element spherically focused 250 kHz transducer. Sixty-three cycles were repeated at 2 kHz for 300 ms at peak negative pressure of 900 kPa pulsed at 0.5 Hz. RESULTS: We report successful suppression of bladder contractions using ultrasound stimulation in 10 animals. The average latency between the initiation of ultrasound and suppression of bladder contractions was 3 min 23 s (±51 s), the average time of contraction suppression was 13 min and 50 s (±2 min 25 s) and the average time from the end of ultrasound to return of contractions was 9 min 37 s (±2 min and 30 s). CONCLUSION: In this work, we demonstrate the ability of targeted transcutaneous ultrasound to inhibit rhythmic bladder contractions in anesthetized rats. Due to its non-invasive nature and ease of application, we believe ultrasound mediated suppression of the micturition reflex is potentially an ideal outpatient treatment of overactive bladder and dysfunctional elimination.

Prospective Evaluation of Sacral Neuromodulation in Children: Outcomes and Urodynamic Predictors of Success.

PURPOSE: Sacral neuromodulation has been demonstrated to improve refractory bowel bladder dysfunction in children. The purpose of the current study was to determine whether results are durable in children after longer followup, whether children with a lower body mass index are at risk for device failure and whether pretreatment urodynamic evaluation can predict posttreatment outcome. MATERIALS AND METHODS: Pediatric patients with refractory bowel bladder dysfunction were enrolled following informed consent and followed prospectively. All patients underwent preoperative videourodynamic evaluation and a 2-stage implantation procedure. Validated questionnaires were used to assess symptom severity and quality of life. Complications were analyzed with regard to treatment required and patient body mass index. RESULTS: During 45 months 30 patients were enrolled. Median age was 8.3 years at enrollment. Median followup was 14.8 months. Patients had significant improvement in quality of life and symptom scores, which persisted at the most recent followup. Patients who had uninhibited detrusor contractions on preoperative urodynamic assessment had significantly greater improvement in symptoms. Of the patients 23% had a complication requiring reoperation, most commonly neurostimulator lead breakage in those with a significantly lower body mass index. CONCLUSIONS: Sacral neuromodulation significantly improves quality of life and symptom severity in children with refractory bowel bladder dysfunction. Children gain greater benefit if they show uninhibited bladder contractions on preoperative urodynamic evaluation. Children have a high rate of lead breakage requiring operative revision, which was seen after minor trauma in those with a lower body mass index.

Impact on family and parental stress of prenatal vs postnatal repair of myelomeningocele.

BACKGROUND: The Management of Myelomeningocele Study was a multicenter, randomized controlled trial that compared prenatal repair with standard postnatal repair for fetal myelomeningocele. OBJECTIVE: We sought to describe the long-term impact on the families of the women who participated and to evaluate how the timing of repair influenced the impact on families and parental stress. STUDY DESIGN: Randomized women completed the 24-item Impact on Family Scale and the 36-item Parenting Stress Index Short Form at 12 and 30 months after delivery. A revised 15-item Impact on Family Scale describing overall impact was also computed. Higher scores reflected more negative impacts or greater stress. In addition, we examined Family Support Scale and Family Resource Scale scores along with various neonatal outcomes. Repeated measures analysis was conducted for each scale and subscale. RESULTS: Of 183 women randomized, 171 women completed the Impact on Family Scale and 172 completed the Parenting Stress Index at both 12 and 30 months. The prenatal surgery group had significantly lower revised 15-item Impact on Family Scale scores as well as familial-social impact subscale scores compared to the postnatal surgery group (P = .02 and .004, respectively). There was no difference in total parental stress between the 2 groups (P = .89) or in any of the Parenting Stress Index Short Form subscales. In addition, walking independently at 30 months and family resources at 12 months were associated with both family impact and parental stress. CONCLUSION: The overall negative family impact of caring for a child with spina bifida, up to 30 months of age, was significantly lower in the prenatal surgery group compared to the postnatal surgery group. Ambulation status and family resources were predictive of impact on family and parental stress.

The Management of Myelomeningocele Study: obstetrical outcomes and risk factors for obstetrical complications following prenatal surgery.

BACKGROUND: The Management of Myelomeningocele Study was a multicenter randomized trial to compare prenatal and standard postnatal closure of myelomeningocele. The trial was stopped early at recommendation of the data and safety monitoring committee and outcome data for 158 of the 183 randomized women published. OBJECTIVE: In this report, pregnancy outcomes for the complete trial cohort are presented. We also sought to analyze risk factors for adverse pregnancy outcome among those women who underwent prenatal myelomeningocele repair. STUDY DESIGN: Pregnancy outcomes were compared between the 2 surgery groups. For women who underwent prenatal surgery, antecedent demographic, surgical, and pregnancy complication risk factors were evaluated for the following outcomes: premature spontaneous membrane rupture ≤34 weeks 0 days (preterm premature rupture of membranes), spontaneous membrane rupture at any gestational age, preterm delivery at ≤34 weeks 0 days, nonintact hysterotomy (minimal uterine wall tissue between fetal membranes and uterine serosa, or partial or complete dehiscence at delivery), and chorioamniotic membrane separation. Risk factors were evaluated using χ2 and Wilcoxon tests and multivariable logistic regression. RESULTS: A total of 183 women were randomized: 91 to prenatal and 92 to postnatal surgery groups. Analysis of the complete cohort confirmed initial findings: that prenatal surgery was associated with an increased risk for membrane separation, oligohydramnios, spontaneous membrane rupture, spontaneous onset of labor, and earlier gestational age at birth. In multivariable logistic regression of the prenatal surgery group adjusting for clinical center, earlier gestational age at surgery and chorioamniotic membrane separation were associated with increased risk of spontaneous membrane rupture (odds ratio, 1.49; 95% confidence interval, 1.01-2.22; and odds ratio, 2.96, 95% confidence interval, 1.05-8.35, respectively). Oligohydramnios was associated with an increased risk of subsequent preterm delivery (odds ratio, 9.21; 95% confidence interval, 2.19-38.78). Nulliparity was a risk factor for nonintact hysterotomy (odds ratio, 3.68; 95% confidence interval, 1.35-10.05). CONCLUSION: Despite the confirmed benefits of prenatal surgery, considerable maternal and fetal risk exists compared with postnatal repair. Early gestational age at surgery and development of chorioamniotic membrane separation are risk factors for ruptured membranes. Oligohydramnios is a risk factor for preterm delivery and nulliparity is a risk factor for nonintact hysterotomy at delivery.

Urinary Phthalate Metabolites in American Alligators (Alligator mississippiensis) from Selected Florida Wetlands.

Phthalates have been shown to cause endocrine disruption in laboratory animals and are associated with altered development of the reproductive system in humans. Further, human have significant exposure to phthalates. However, little is known concerning the exposure of wildlife to phthalates. We report urinary phthalate metabolite concentrations from fifty juvenile alligators from three Florida lakes and a site in the Everglades. Urinary phthalate monoester concentrations varied widely among alligators from the different sites but also among alligators from the same site. Mono-2-ethylhexy phthalate and monobutyl phthalate were found in most samples of alligator urine with maximums of 35,700 ng/mL and 193 ng/mL, respectively. Monobenzyl phthalate was found in 5 alligators with a maximum of 66.7 ng/mL. Other monoesters were found in only one or two alligator urine samples. The wide variation within and among sites, in addition to the high levels of mEHP, mBP and mBzP, is consistent with exposure arising from the intermittent spraying of herbicide formulations to control invasive aquatic plants in Florida freshwater sites. Phthalate diesters are used as adjuvants in many of these formulations.

Bullying and lower urinary tract symptoms: why the pediatric urologist should care about school bullying.

PURPOSE: Bullying has become a social plague associated with various deleterious outcomes. We hypothesized that pediatric lower urinary tract symptoms could be associated with exposure to bullying. MATERIALS AND METHODS: We assessed exposure to school bullying via the Setting the Record Straight bullying questionnaire in children 8 to 11 years old being evaluated for lower urinary tract symptoms at our pediatric urology clinic. Lower urinary tract symptoms were quantified with the Vancouver Symptom Score. Children 8 to 11 years old presenting for pediatric well visits also completed the questionnaires. Linear regression assessed the relationship between Vancouver Symptom Score and bullying score. Categorical variables were compared by chi-square test, while continuous variables were compared using the Student t-test. RESULTS: A total of 113 children at the urology clinic and 63 children in the primary care setting consented to participate. There were significant differences between the 2 populations, including gender and race, with significantly more perpetrators of bullying in the primary care group (7.9% vs 0.9%, p = 0.02). When looking specifically at the urology group, there was a significant association between Vancouver Symptom Score and self-perceived (p <0.001) and peer perceived (p <0.001) victimization scores. In the primary care group there was also a significant association between Vancouver Symptom Score and self-perceived (p = 0.01) and peer perceived (p = 0.001) bullying perpetrator scores. Of children seen at the primary care office 33% had a significant Vancouver Symptom Score. CONCLUSIONS: Although bullying exposure is multifactorial, we found that Vancouver Symptom Score can be associated with bullying victimization and perpetrator scores.

Spatial variation in hyperthermia emergency department visits among those with employer-based insurance in the United States - a case-crossover analysis.

BACKGROUND: Predictions of intense heat waves across the United States will lead to localized health impacts, most of which are preventable. There is a need to better understand the spatial variation in the morbidity impacts associated with extreme heat across the country to prevent such adverse health outcomes. METHODS: Hyperthermia-related emergency department (ED) visits were obtained from the Truven Health MarketScan(®) Research dataset for 2000-2010. Three measures of daily ambient heat were constructed using meteorological observations from the National Climatic Data Center (maximum temperature, heat index) and the Spatial Synoptic Classification. Using a time-stratified case crossover approach, odds ratio of hyperthermia-related ED visit were estimated for the three different heat measures. Random effects meta-analysis was used to combine the odds ratios for 94 Metropolitan Statistical Areas (MSA) to examine the spatial variation by eight latitude categories and nine U.S. climate regions. RESULTS: Examination of lags for all three temperature measures showed that the odds ratio of ED visit was statistically significant and highest on the day of the ED visit. For heat waves lasting two or more days, additional statistically significant association was observed when heat index and synoptic classification was used as the temperature measure. These results were insensitive to the inclusion of air pollution measures. On average, the maximum temperature on the day of an ED visit was 93.4°F in 'South' and 81.9°F in the 'Northwest' climatic regions of United States. The meta-analysis showed higher odds ratios of hyperthermia ED visit in the central and the northern parts of the country compared to the south and southwest. CONCLUSION: The results showed spatial variation in average temperature on days of ED visit and odds ratio for hyperthermia ED visits associated with extreme heat across United States. This suggests that heat response plans need to be customized for different regions and the potential role of hyperthermia ED visits in syndromic surveillance for extreme heat.

To tell or not: parental thoughts on disclosure of urologic surgery to their child.

PURPOSE: Literature pertaining to surgical disclosure to the pediatric patient is lacking. We hypothesized parents would find it difficult to disclose urologic surgery to a child. MATERIALS AND METHODS: Parents of patients <5 years old undergoing urologic surgery were contacted for telephone survey. Parents were asked about future plans of surgical disclosure, comfort with disclosure, and any support received. RESULTS: 98 parents consented to study participation. 87% of surgeries were on the genitalia with 62% being minor genitalia surgery (i.e. circumcision). 70% of parents would tell their child about minor genital surgery while 84% would tell about major genital surgery (p=0.07). 4 of 20 parents of children undergoing hypospadias repair (major genital surgery) did not plan to tell their child about surgery. All parents of children undergoing non-genital surgery would tell. Of all parents planning to tell their children about surgery, only 14% were nervous. 34% of parents would find guidance in talking to their child helpful despite the majority (90%) stating no guidance had ever been provided. CONCLUSIONS: Parents seem comfortable discussing urologic surgeries with a child but about 1/3 would appreciate further counseling. 20% of parents of children undergoing hypospadias repair hope to avoid telling their child.

A randomized trial of prenatal versus postnatal repair of myelomeningocele.

BACKGROUND: Prenatal repair of myelomeningocele, the most common form of spina bifida, may result in better neurologic function than repair deferred until after delivery. We compared outcomes of in utero repair with standard postnatal repair. METHODS: We randomly assigned eligible women to undergo either prenatal surgery before 26 weeks of gestation or standard postnatal repair. One primary outcome was a composite of fetal or neonatal death or the need for placement of a cerebrospinal fluid shunt by the age of 12 months. Another primary outcome at 30 months was a composite of mental development and motor function. RESULTS: The trial was stopped for efficacy of prenatal surgery after the recruitment of 183 of a planned 200 patients. This report is based on results in 158 patients whose children were evaluated at 12 months. The first primary outcome occurred in 68% of the infants in the prenatal-surgery group and in 98% of those in the postnatal-surgery group (relative risk, 0.70; 97.7% confidence interval [CI], 0.58 to 0.84; P<0.001). Actual rates of shunt placement were 40% in the prenatal-surgery group and 82% in the postnatal-surgery group (relative risk, 0.48; 97.7% CI, 0.36 to 0.64; P<0.001). Prenatal surgery also resulted in improvement in the composite score for mental development and motor function at 30 months (P=0.007) and in improvement in several secondary outcomes, including hindbrain herniation by 12 months and ambulation by 30 months. However, prenatal surgery was associated with an increased risk of preterm delivery and uterine dehiscence at delivery. CONCLUSIONS: Prenatal surgery for myelomeningocele reduced the need for shunting and improved motor outcomes at 30 months but was associated with maternal and fetal risks.
