Case Report: Blinatumomab as upfront consolidation and maintenance therapy in a pediatric patient with high-risk B-cell acute lymphoblastic leukemia.

Introduction: B-cell acute lymphoblastic leukemia (B-ALL) is the most common malignancy in children. The current conventional chemotherapy regimens have high overall survival but with significant short- and long-term toxicities, sometimes requiring delay and termination of chemotherapy. Bispecific T-cell engager antibody blinatumomab has been successful in achieving bone marrow remission and acting as bridging therapy in minimal residual disease (MRD)-positive relapsed adult and pediatric B-ALL patients. Its role as upfront therapy is being explored. Here, we report the first case to our knowledge showing the feasibility, tolerability, and sustained remission using blinatumomab upfront as consolidation and maintenance therapy for 2 years in a pediatric patient with high-risk B-ALL who had significant toxicities with conventional chemotherapy. 'Case presentation: An 11-year-old Hispanic girl presented with complaints of fever, abdominal pain, and fatigue. On further evaluation, she had tachycardia, pallor, cervical lymphadenopathy, and pancytopenia. Bone marrow studies confirmed high-risk B-ALL. The patient was started on induction chemotherapy per AALL1131. Her induction course was complicated by syncope, febrile neutropenia, and invasive cryptococcal fungal infection. End-of-induction bone marrow results were MRD negative. Further chemotherapy was withheld due to cardiopulmonary and renal failure, along with ventricular arrhythmias requiring intensive care. The patient received two cycles of blinatumomab as consolidation therapy and then transitioned back to conventional consolidation therapy; however, it was terminated mid-consolidation due to Pseudomonas and Aspergillus sepsis. She was then given blinatumomab maintenance therapy for 2 years and tolerated it well without any irreversible toxicity. She had an episode of Staphylococcus epidermidis sepsis and pneumonia treated by antibiotics and a single episode of a seizure while on blinatumomab therapy. At the time of publication, she is 25 months off treatment and in sustained remission without any further transplant or chemotherapy. She received monthly intravenous immunoglobulin G during the blinatumomab maintenance. Conclusion: Blinatumomab given upfront as consolidation and maintenance therapy for 2 years in a pediatric high-risk B-ALL patient with significant toxicities to conventional chemotherapy was feasible and very well tolerated without any irreversible toxicity and led to sustained remission without any bridging transplant or further chemotherapy.

Use of retrograde pyelogram to plan for miniature open incision in pediatric pyeloplasty.

INTRODUCTION: As robotic-assisted surgery becomes increasingly utilized for pediatric ureteropelvic junction (UPJ) obstruction, open surgeons have countered by using muscle-splitting, miniature (≤2 cm) incisions. To prepare for this type of incision during pyeloplasty, it is necessary to define the exact location of the UPJ. The use of retrograde pyelogram (RPG) at the time of pyeloplasty helps the surgeon to identify the exact location of UPJ, and thus be able to use a muscle-splitting, miniature incision for open pyeloplasty. OBJECTIVE: We hypothesize that when performing a muscle-splitting, miniature incision open approach; preoperative RPG frequently changes the traditional pyeloplasty flank incision at the tip of the 11th or 12th rib. MATERIALS & METHODS: A retrospective review of open pyeloplasties performed by a single surgeon at our institution from 7/1/2010 to 12/31/2018 was performed to determine rate of use of RPG, open pyeloplasty incision location and to determine what factors are predictive of incisional site. RESULTS: 114 of 122 (93.4%) patients with 115 renal units had pyeloplasties with preoperative RPG performed. Of the 8 procedures without RPG, two had a pelvic kidney diagnosed prior to surgery, two had narrow ureteric orifices that were difficult to cannulate, and four had associated reflux. In 31/115 (27%) pyeloplasties the incision was changed from a standard incision position at the 11th or 12th rib to an alternative incision (i.e. extended muscle-transecting incision at the tip of the 11th or 12th rib, or to an alternate incision site including Gibson, McBurney's incision, or low anterior abdominal incision). 84/115 (73.0%) had a miniature (<2 cm) incision at the tip of the 11th or 12th rib. Grade IV hydronephrosis was a significant predictor for changing the traditional incision site (p = 0.02). Preoperative nephrostomy tube insertion was also associated with an increased likelihood of having an alternate incision (p = 0.04). Incision site was not significantly affected by age of the patient at surgery, patient sex, size of the affected kidney, T1/2 times of <30 min, split function of <30%, kidney length differential, or laterality. CONCLUSION: The consistent use of RPG prior to pyeloplasty helps surgeons to plan for a small muscle-splitting, miniature open incisions. In our experience, 27% of pyeloplasties required alternative incision sites based on the results of pre-operative RPG.

Characteristics of Female Genital Restoration Surgery for Congenital Adrenal Hyperplasia Using a Large-scale Administrative Database.

OBJECTIVE: To analyze nationwide information on the timing of surgical procedures, cost of surgery, hospital length of stay following surgery, and surgical complications of female genital restoration surgery (FGRS) in females with congenital adrenal hyperplasia (CAH). MATERIALS AND METHODS: We used the Pediatric Health Information System database to identify patients with CAH who underwent their initial FGRS in 2004-2014. These patients were identified by an International Classification of Diseases, Ninth Revision (ICD-9) diagnosis code for adrenogenital disorders (255.2) in addition to a vaginal ICD-9 procedure code (70.x, excluding vaginoscopy only) or perineal ICD-9 procedure code (71.x), which includes clitoral operations (71.4). RESULTS: A total of 544 (11.8%) females underwent FGRS between 2004 and 2014. Median age at initial surgery was 9.9 months (interquartile range 6.8-19.1 months). Ninety-two percent underwent a vaginal procedure, 48% underwent a clitoral procedure, and 85% underwent a perineal procedure (non-clitoral). The mean length of stay was 2.5 days (standard deviation 2.5 days). The mean cost of care was $12,258 (median $9,558). Thirty-day readmission rate was 13.8%. Two percent underwent reoperation before discharge, and 1 (0.2%) was readmitted for a reoperation within 30 days. Four percent had a perioperative surgical complication. CONCLUSION: Overall, 12% of girls with CAH underwent FGRS at one of a national collaborative of freestanding children's hospitals. The majority underwent a vaginoplasty as a part of their initial FGRS for CAH. Clitoroplasty was performed on less than half the patients. Overall, FGRS for CAH is performed at a median age of 10 months and has low 30-day complication and immediate reoperation rates.

Complications and Outcomes of Pregnancy and Cesarean Delivery in Women With Neuropathic Bladder and Lower Urinary Tract Reconstruction.

OBJECTIVE: To determine the outcomes of pregnancy and cesarean delivery (CD) in women with neuropathic bladder (NB) and pediatric lower urinary tract reconstruction (LUTR) as these women often have normal fertility and may become pregnant. METHODS: We reviewed consecutive patients with NB due to spinal dysraphism who underwent LUTR, became pregnant, and had a CD at our institution from July 2001 to June 2016. We collected data on demographics, hydronephrosis, symptomatic urinary tract infection, continence, and catheterization during pregnancy. CD data included gestational age, abdominal or uterine incisions, and complications. RESULTS: We identified 18 pregnancies in 11 women. Fifteen live newborns were delivered via CD (53.3% term births). Thirteen of 15 patients (86.7%) developed new (10) or worsening (3) hydronephrosis. Six of 13 patients (46.2%) underwent nephrostomy tube placement. Eight of 15 patients (53.3%) developed difficulty catheterizing (66.7% via native urethra, 44.4% via catheterizable channel); 50.0% of patients required an indwelling catheter. Five of 15 patients (33.3%) developed urinary incontinence during pregnancy. Ten of 15 patients (66.7%) had a urinary tract infection (30.0% febrile). A urologist was present for all CDs: 5 were scheduled, 10 occurred emergently. Complications occurred in 40.0% (5 cystotomies, 1 bowel deserosalization, 1 vaginal laceration). All cystotomies occurred during emergent CD. Three patients (20.0%) developed urinary fistulae after emergent CD. CONCLUSIONS: Women with NB and LUTR have high rates of complications during pregnancy and CD, despite routine involvement of urologists. Women with prolonged labor, previous CD, or those with a history of noncompliance developed the worst complications. Based on our experience, a urologist should always be present and participate in the CD.

Parental decisional regret and views about optimal timing of female genital restoration surgery in congenital adrenal hyperplasia.

PURPOSE: The role of female genital restoration surgery (FGRS) in girls with congenital adrenal hyperplasia (CAH) is controversial, with no long-term parent-reported outcomes available. Decisional regret (DR) affects most parents after their children's treatment of pediatric conditions, including hypospadias. We aimed to assess parental DR after FGRS in infancy or toddlerhood and explore optimal timing for surgery. MATERIALS AND METHODS: One-hundred and six parents of females with CAH undergoing FGRS before 3 years old and followed at our institution (1999-2017) were invited to enroll online. Higher Decision Regret Scale (DRS) scores indicated greater DR (range 0-100). Participants also reported preferred FGRS timing relative to their surgery (earlier, same, later/delayed). Non-parametric statistical tests were used. RESULTS: Thirty-nine parents (median 4.4 years after FGRS) participated (36.8% response rate). Median age at FGRS was 9 months. Median DRS score was 0 (mean: 5.0). Overall, 20.5% of parents reported some regret (all mild-moderate) (Figure). Fewer parents reported DR after FGRS compared with published DR after hypospadias repair (50-92%, p ≤ 0.001) or adenotonsillectomy (41-45%, p ≤ 0.03). No parent preferred delayed FGRS. Seven parents (18.1%) preferred earlier surgery, especially when performed after birthday (80.0% vs. 8.8%, p = 0.004). DISCUSSION: We present the first report of validated long-term parent-reported outcomes after FGRS in infant and toddler girls with CAH. One limitation is that this is largely a single surgeon series. Reasons for the observed low levels of DR are likely multifactorial. Far from a definitive study, we aimed to provide parents willing to share about their experience an opportunity to do so. For that reason, selection bias may exist in our study. While parents with higher DR were potentially less likely to participate because of mistrust of the medical establishment, those with a negative experience may in fact be more likely to voice their opinions. A low participation rate was likely a result of the sensitive nature of FGRS, a desire for privacy, and inability to locate parents. A larger study will be required to assess how DR is affected by sexual function, genital appearance and complications, and DR among women with CAH. CONCLUSIONS: Parents of females with CAH report low levels of DR after FGRS in infancy and toddlerhood. This appears to be lower than after other genital and non-genital pediatric procedures. When present, parental DR is usually mild. No parents preferred delayed surgery, even among those with DR. Some preferred earlier surgery.

Validation of QUALAS-T, a health-related quality of life instrument for teenagers with spina bifida.

INTRODUCTION: We aimed to develop and validate a self-reported QUAlity of Life Assessment in Spina bifida for Teenagers (QUALAS-T). MATERIAL AND METHODS: We drafted a 46-question pilot instrument using a patient-centered comprehensive item generation/refinement process. A group of 13-17 years olds with spina bifida (SB) was recruited online via social media and in person at SB clinics (2013-2015). Healthy controls were recruited during routine pediatrician visits. Final questions were identified based on clinical relevance, factor analysis and domain psychometrics. Teenagers with SB completed the validated generic Kidscreen-27 instrument. RESULTS: Median age of 159 participants was 15.2 years (42.0% male, 77.4% Caucasian), similar to 58 controls (p ≥ 0.06). There were 102 online and 57 clinic participants (82.8% of eligible). Patients, parents and an expert panel established face and content validity of the 2-domain, 10-question QUALAS-T. Internal consistency and test-retest reliability were high for the Family and Independence and Bladder and Bowel domains (Cronbach's alpha: 0.76-0.78, ICC: 0.72-0.75). The Bladder and Bowel domain is the same for QUALAS-T , QUALAS-A for adults and QUALAS-C for children. Correlations between QUALAS-T domains were low (r = 0.34), indicating QUALAS-T can differentiate between distinct HRQOL components. Correlations between QUALAS-T and Kidscreen-27 were also low (r ≤0.41). QUALAS-T scores were lower in teenagers with SB than without (p <0.0001). CONCLUSIONS: QUALAS-T is a short, valid HRQOL tool for adolescents with SB, applicable in clinical and research settings. Since the Bladder & Bowel domains for all QUALAS versions are the same, Bladder and Bowel HRQOL can be measured on the same scale from age 8 through adulthood.

Does endoscopy of difficult to catheterize channels spare some patients from formal open revision?

INTRODUCTION: Patients with continent catheterizable channels (CCC) may develop difficulty catheterizing postoperatively. In complex cases, endoscopic evaluation with indwelling catheter placement may be indicated, but the risk factors for subsequent formal channel revision are not well defined. The purpose of this study was to determine the risk factors for formal channel revision after attempted endoscopic management of difficulty catheterizing. MATERIALS AND METHODS: We performed an IRB-approved retrospective review of pediatric (<21 years old) patients undergoing CCC construction at our institution from 1999 to 2014 to identify patients who underwent endoscopy for difficulty catheterizing. Fisher's Exact test was used for categorical data and Mann-Whitney U test for continuous variables to examine the association between endoscopic intervention and subsequent formal revision. RESULTS: Sixty-three of 434 patients (14.5%) underwent at least one endoscopy for reported difficulty catheterizing their CCC, with 77.8% of these requiring additional intervention during endoscopy (catheter placement, dilation, etc.). Of these, almost half with functioning channels (43.5%, 27/62) were managed successfully with endoscopy without formal revision; six (22.2%) of whom underwent more than one endoscopy. These 27 patients continued to catheterize well at a median follow-up of 3.2 years (interquartile range 2.0-6.0). Patients requiring revision had a median of 1.7 years between CCC creation and first endoscopy, versus 1.6 years in those who were not revised (p = 0.60). There was no statistically significant difference between revised and non-revised channels in terms of patient age at CCC creation, underlying patient diagnosis, status of bladder neck, stomal location, or channel type (p ≥ 0.05) (see Table). CONCLUSION: Approximately half of our patients did not require a formal channel revision after endoscopic management. We did not identify any specific risk factors for subsequent formal revision of a CCC. We recommend performing at least one endoscopic evaluation for those with difficulty catheterizing prior to proceeding with formal open revision.

Early Bubble Continuous Positive Airway Pressure: Investigating Interprofessional Best Practices for the NICU Team.

Premature neonates delivered <32 completed weeks gestation are unprepared to handle the physiologic demands of extrauterine life. Within the respiratory system, alveolar instability and collapse can cause decreased functional residual capacity, impaired oxygenation, and hypoxemia leading to respiratory distress syndrome. Supportive measures are indicated immediately after birth to establish physiologic stability including bubble continuous positive airway pressure (CPAP) or endotracheal intubation and mechanical ventilation. CPAP is a noninvasive, gentle mode of ventilation that can mitigate the effects of lung immaturity, but prolonged use can increase the risk for nasal breakdown. Strategies to mitigate this risk must be infused as best practices in the NICU environment. The purpose of this article is to propose an evidence-based best practice care bundle for the early initiation of CPAP in the delivery room and associated skin barrier protection strategies for premature neonates <32 weeks gestation and weighing <1,500 g.

A snapshot of the adult spina bifida patient - high incidence of urologic procedures.

INTRODUCTION: To describe the urologic outcomes of contemporary adult spina bifida patients managed in a multidisciplinary clinic. MATERIAL AND METHODS: A retrospective chart review of patients seen in our adult spina bifida clinic from January 2004 to November 2011 was performed to identify urologic management, urologic surgeries, and co-morbidities. RESULTS: 225 patients were identified (57.8% female, 42.2% male). Current median age was 30 years (IQR 27, 36) with a median age at first visit of 25 years (IQR 22, 30). The majority (70.7%) utilized clean intermittent catheterization, and 111 patients (49.3%) were prescribed anticholinergic medications. 65.8% had urodynamics performed at least once, and 56% obtained appropriate upper tract imaging at least every other year while under our care. 101 patients (44.9%) underwent at least one urologic surgical procedure during their lifetime, with a total of 191 procedures being performed, of which stone procedures (n = 51, 26.7%) were the most common. Other common procedures included continence procedures (n = 35, 18.3%) and augmentation cystoplasty (n = 29, 15.2%). Only 3.6% had a documented diagnosis of chronic kidney disease and 0.9% with end-stage renal disease. CONCLUSIONS: Most adult spina bifida patient continue on anticholinergic medications and clean intermittent catheterization. A large percentage of patients required urologic procedures in adulthood. Patients should be encouraged to utilize conservative and effective bladder management strategies to reduce their risk of renal compromise.

Progressive Independence in Clinical Training: Perspectives of a National, Multispecialty Panel of Residents and Fellows.

BACKGROUND: Progressive independence in patient care activities is imperative for residents' readiness for practice and patient safety of those cared for by graduates of residency programs. However, establishing a standardized system of progressive independence is an ongoing challenge in graduate medical education. OBJECTIVE: We aggregated trainees' perspectives on progressive independence, developed a model of the ideal state, and suggested actionable improvements. METHODS: A multispecialty, nationally representative group of trainees conducted a structured exercise that (1) described the attributes of an ideal system of graduated responsibility; (2) compared the current system to that ideal; (3) developed benchmarks to reinforce best practices; and (4) identified approaches to motivate programs to adopt best practices. RESULTS: At the core of an ideal model of graduated responsibility is a well-structured curriculum and assessment of individual learners using educational milestones and patient outcomes. The ideal model also includes robust faculty development and emphasizes faculty mentorship. To address legal and financial restrictions that pose barriers to progressive independent, objective outcome criteria like the milestones could be used to ask payers to alter payment restrictions for work performed by senior trainees, providing financial incentives for programs to encourage appropriate independent practice. Recognition of high-performing programs at the national level could motivate others to adopt best practices. CONCLUSIONS: A multifaceted approach, incorporating robust 2-way feedback about skill level and autonomy between residents and faculty, along with improved faculty development in this area, is needed to optimize residents' attainment of progressive independence. There are incentives to move programs and institutions toward this optimal model.

Adolescent Varicoceles and Infertility.

Varicoceles are associated with testicular atrophy and abnormal spermatogenesis. Varicocele-related testicular damage is thought to be progressive in nature. Adult varicoceles are common in men with infertility, and varicocele repair in this population has demonstrated improved semen parameters and paternity outcomes. However, without solid objective endpoints (reproducible semen analyses, paternity), the indications for adolescent varicocele repair remain controversial. Given the controversy surrounding adolescent varicocele management, it is not surprising that surveys of pediatric urologists have revealed a lack of consensus on diagnostic approaches, treatment decisions, and operative approaches.

Quality of life related to urinary continence in adult spina bifida patients.

INTRODUCTION: To analyze the correlations of bladder management technique, ambulatory status and urologic reconstruction on quality of life (QOL) as affected by urinary symptoms in adult spina bifida (SB) patients. MATERIAL AND METHODS: Sixty-six adult SB patients completed the RAND 36-Item Health Survey (mSF-36) and Incontinence Quality of Life (I-QOL). Demographic information, history of urinary reconstruction, and bladder management techniques were reviewed and analyzed with respect to survey scores. RESULTS: Mean age of patients was 32.3 (SD ±7.2) years and 44 patients (66.7%) were female. Forty-five patients (68.2%) were mainly ambulatory, 21 (31.8%) use a wheelchair and 10 (15.2%) had urologic reconstruction, while 56 (83.3%) did not. Twelve patients (18.2%) void, 42 (63.6%) perform clean intermittent catheterization (CIC), 4 (6.1%) use an indwelling catheter, 3 (4.5%) have an ileal conduit (IC) and 5 (7.6%) mainly use diapers. Mean mSF-36 General Health score was 56.5 (SD ±22.9) and mean I-QOL Sum score was 50.9 (SD ±21.7), where lower scores reflect lower QOL. mSF-36 and I-QOL scores did not significantly correlate with bladder management technique, ambulatory status or urologic reconstruction. A correlation was noted between I-QOL scales and most mSF-36 scales (all p <0.02). CONCLUSIONS: In our cohort study of adult SB patients, bladder management technique and urologic reconstruction did not correlate with urinary (I-QOL) or general health (mSF-36) domains, although I-QOL and mSF-36 scores correlated closely, suggesting urinary continence is significantly related to general QOL. However, we are unable to identify a single factor that improves either urinary or general QOL.

Association of Uninterrupted Oral Anticoagulation During Cardiac Device Implantation with Pocket Hematoma.

PURPOSE: Implantation of permanent pacemakers (PPMs) or implantable cardiac defibrillators (ICDs) may be complicated by the development of pocket hematomas. Current practice guidelines provide little guidance to clinicians about the preferred strategy for chronic oral anticoagulation (OAC). The purpose of this study was to examine the frequency and clinical significance of pocket hematoma among patients receiving uninterrupted OAC during cardiac device implantation. METHODS: This was a retrospective cohort study of adult patients undergoing cardiac device implantation between January 1, 2011, and December 31, 2012, at an academic teaching hospital. Medical records were reviewed for demographics, comorbidities, and medications. The primary outcome was development of pocket hematomas within 30 days of device implantation. Clinical significance was based on the need for additional intervention. Data were assessed using descriptive statistics, logistic regression, and chi-square tests. RESULTS: The final cohort included 380 patients. The median age was 68.4 years, and 56.6% were male. Cardiovascular comorbidities were common. Among 80 patients receiving uninterrupted OAC, 71.3% were taking warfarin, 11.2% rivaroxaban, and 17.5% dabigatran. The incidence of pocket hematomas for the entire cohort was 9.7%, of which 1.3% were clinically significant. Pocket hematoma occurred in 21.4% of patients continued on OAC versus 7.7% of those not anticoagulated (P = .001). Pocket hematoma was more common among those receiving ICDs than PPMs (18.5% vs 5.7%, respectively; P < .001). CONCLUSIONS: Continuing chronic OAC increased pocket hematoma formation but most were clinically insignificant. Pocket hematoma occurred irrespective of the oral anticoagulant drug used, but additional study is needed to determine comparative risks among the drugs.

Robotic-assisted laparoscopic transplant-to-native ureteroureterostomy in a pediatric patient.

OBJECTIVE: Management of late-occurring or long (>3 cm) post-transplant ureteral strictures usually requires open surgery, which includes ureteroureterostomy (UU) as an option. Recently, robotic-assisted laparoscopic UU for ectopic ureters in a duplicated system has been described. We report a case of a robotic-assisted laparoscopic transplant-to-native side-to-side UU in a 14-year-old girl with a stricture of nearly two-thirds of her transplant ureter 5 years after a cadaveric renal transplant. RESULTS: Robotic-assisted laparoscopic native-to-transplant UU was performed with resultant durable improvement in the patient's hydronephrosis and kidney function. CONCLUSION: Based on our case and review of the literature, robotic-assisted laparoscopic UU should be part of the armamentarium for long or late-occurring transplant ureteral strictures.

Contemporary national comparison of open, laparoscopic, and robotic-assisted laparoscopic pediatric pyeloplasty.

OBJECTIVE: We sought to determine current and longitudinal trends in the usage of open (OP), laparoscopic (LP), and robotic pyeloplasties. (RALP) Furthermore, we aimed to describe patient and hospital level characteristics associated with the use of minimally invasive pyeloplasties (MIP) and to compare basic utilization metrics for each approach. MATERIALS/METHODS: The 2000, 2003, 2006, and 2009 Kid's Inpatient Databases (KID) were used to determine current and longitudinal trends. As a result of a specific billing code for robotic surgery introduced in 2008, the 2009 KID database was used for analysis of RALP. Patient and hospital characteristics examined included: age, gender, race, insurance status, hospital location, and academic status. Utilization metrics of length of stay (LOS) and cost were determined from each modality. RESULTS: In 2009, there were 3354 pediatric pyeloplasties performed in the USA (85% OP, 3% LP, 12% RP). Compared with 2000, this represents an 11.7% decrease in the overall number of pyeloplasties but a progressive increase in MIP from 0.34% in 2000 to 11.7%. Mean patient age was 3.7 years for OP, 9.3 years for LP and 9.9 years for RALP. MIP was more commonly performed in females, Caucasians, patients with private insurance, at urban hospitals and at teaching hospitals. Although length of stay (LOS) in days was statistically lower for MIP (3.46 OP, 2.86 LP, 1.96 RP, p < 0.001), total cost between the groups was not statistically different. On multivariable logistic regression analysis, age (OR 1.17, p < 0.001) increased the odds of MIP whereas lack of private insurance decreased the odds of MIP (OR 0.62, p = 0.002). CONCLUSION: Although utilization of MIP is increasing in the USA, especially in older children, OP remains predominant. MIP was associated with a decrease in LOS. The odds of MIP were higher in older children, whereas the lack of private insurance decreased the odds of MIP.

Diagnosis of varicoceles in men undergoing vasectomy may lead to earlier detection of hypogonadism.

OBJECTIVE: To determine the temporal relationship between vasectomy, varicocele, and hypogonadism diagnosis. Many young men undergo their first thorough genitourinary examination in their adult lives at the time of vasectomy consultation, providing a unique opportunity for diagnosis of asymptomatic varicoceles. Varicoceles have recently been implicated as a possible reversible contributor to hypogonadism. Hypogonadism may be associated with significant adverse effect, including decreased libido, impaired cognitive function, and increased cardiovascular events. Early diagnosis and treatment of hypogonadism may prevent these adverse sequelae. METHODS: Data were collected from the Truven Health Analytics MarketScan database, a large outpatient claims database. We reviewed records between 2003 and 2010 for male patients between the ages of 25 and 50 years with International Classification of Diseases, Ninth Revision codes for hypogonadism, vasectomy, and varicocele, and queried dates of first claim. RESULTS: A total of 15,679 men undergoing vasectomies were matched with 156,790 men with nonvasectomy claims in the same year. Vasectomy patients were diagnosed with varicocele at an earlier age (40.9 vs 42.5 years; P=.009). We identified 224,817 men between the ages of 25 and 50 years with a claim of hypogonadism, of which 5883 (2.6%) also had a claim of varicocele. Men with hypogonadism alone were older at presentation compared with men with an accompanying varicocele (41.3 [standard deviation±6.5] vs 34.9 [standard deviation±6.1]; P<.001). CONCLUSION: Men undergoing vasectomies are diagnosed with varicoceles at a younger age than age-matched controls. Men with varicoceles present with hypogonadism earlier than men without varicoceles. Earlier diagnosis of varicocele at the time of vasectomy allows for earlier detection of hypogonadism.

Risk of bladder cancer in patients with spina bifida: case reports and review of the literature.

PURPOSE: This article presents four cases of patients with spina bifida who developed bladder cancer while under our care and provides a literature review on the incidence, initial presentation, possible etiologies, and role for screening for bladder cancer in the neurogenic bladder population. METHODS: Case reports of four patients are presented followed by a literature review of the current available studies. RESULTS: Patients with spina bifida present with bladder cancer at an atypically young age with very advanced disease. The dire prognosis associated with bladder cancer in these patients demands that we provide better treatment, diagnosis, and prevention modalities. However, the potential morbidity, financial burden, and lack of proven benefit discourage cystoscopic screening in this patient population. Until we have more data on how to best serve spina bifida patients, this population should receive careful and regular urologic follow-up. CONCLUSION: Given the atypical young age of presentation and very advanced nature of bladder cancer in the spina bifida population, the authors strongly recommend that any new bladder changes, such as including increased urinary leakage, pain, recurrent infections, or increased gross hematuria, prompt immediate urologic referral for endoscopic evaluation and biopsy as indicated.

Pediatric genital injury: an analysis of the National Electronic Injury Surveillance System.

OBJECTIVE: To describe the characteristics of pediatric genital injuries presenting to United States emergency departments (EDs). METHODS: A retrospective cohort study utilizing the U.S. Consumer Product Safety Commission (CPSC) National Electronic Injury Surveillance System (NEISS) from 1991-2010 to evaluate pediatric genital injuries was performed. RESULTS: Pediatric genital injuries represented 0.6% of all pediatric injuries with the incidence of injuries rising through the period studied, 1991-2010. The mean age at injury was 7.1 years old and was distributed 56.6% girls and 43.4% boys. A total of 43.3% had lacerations and 42.2% had contusions/abrasions. The majority of injuries occurred at home (65.9%), and the majority of patients (94.7%) were treated and released from the hospital. The most common consumer products associated with pediatric genital trauma were: bicycles (14.7% of all pediatric genital injuries), bathtubs (5.8%), daywear (5.6%), monkey bars (5.4%), and toilets (4.0%). CONCLUSION: Although pediatric genital injuries represent a small proportion of overall injuries presenting to the emergency department, genital injuries continue to rise despite public health measures targeted to decrease childhood injury. Our results can be used to guide further prevention strategies for pediatric genital injury.

A protocol based, electronic medical record enabled care coordination system improves the timeliness and efficiency of care for patients with hematuria.

PURPOSE: We determined whether including a care coordination system to manage the referral process for hematuria would lead to improved quality of care. MATERIALS AND METHODS: Inflection Navigator, a protocol based, electronic medical record enabled care coordination system, was developed to support primary care physicians evaluating newly discovered hematuria. We studied the system for patients referred for microscopic and gross hematuria from May 2009 to May 2010. We compared outcomes in these 106 patients and in 105 referred to our urology department for hematuria during the same period who did not use the system. RESULTS: Patients in the care coordination group completed the evaluation in a significantly shorter time with more than a 1-month difference in time between referral and the completion of the imaging and cystoscopy components of the assessment (mean 40.9 vs 74.1 days, p <0.05). This system potentially lowered health care costs by decreasing the mean ± SD number of urology visits needed to complete an evaluation from 2.1 ± 1.5 in the standard referral group to 1.6 ± 1.4 in the care coordination group (p <0.05). CONCLUSIONS: A protocol based care coordination system for hematuria decreased the time needed to complete an evaluation and decreased the number of overall visits required to make a final diagnosis. Thus, the Inflection Navigator system is an example of an electronic medical record enabled process innovation that can improve the efficiency of care while potentially lowering health care costs.
