Müllerian anomalies in girls with congenital solitary kidney. Pediatr Nephrol 2024; 39:1783-1789. [PMID: 38197956 PMCID: PMC11026257 DOI: 10.1007/s00467-023-06266-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/24/2023] [Revised: 12/14/2023] [Accepted: 12/15/2023] [Indexed: 01/11/2024]
Abstract
BACKGROUND The prevalence of Müllerian anomalies (MA) among patients with congenital solitary functioning kidney (SFK) is not well defined. A delay in diagnosis of obstructive MA can increase the risk of poor clinical outcomes. This study describes the prevalence of MA in patients with congenital SFK. METHODS A retrospective review was performed of patients within the Nationwide Children's Hospital system with ICD9 or ICD10 diagnostic codes for congenital SFK defined as either unilateral renal agenesis (URA) or multicystic dysplastic kidney (MCDK) and confirmed by chart review. Patients with complex urogenital pathology were excluded. Renal anomaly, MA, reason for and type of pelvic evaluation, and age of diagnosis of anomalies were evaluated. RESULTS Congenital SFK occurred in 431 girls due to URA (209) or MCDK (222). Pelvic evaluation, most commonly by ultrasound for evaluation of abdominal pain or dysmenorrhea, occurred in 115 patients leading to MA diagnosis in 60 instances. Among 221 patients ages 10 years and older, 104 underwent pelvic evaluation and 52 were diagnosed with an MA of which 20 were obstructive. Isolated uterine or combined uterine and vaginal anomalies were the most common MA. MA were five-fold more common in patients with URA compared to MCDK. In 75% of patients, the SFK was diagnosed prior to the MA. CONCLUSIONS The prevalence of MA in patients with congenital SFK was 24% among those age 10 years or older, and 38% were obstructive. This justifies routine screening pelvic ultrasound in girls with congenital SFK to improve early diagnosis.

Learning from the past: How lessons from Hinman syndrome can inform the psychological management of lower urinary tract dysfunction. J Pediatr Urol 2024:S1477-5131(24)00048-2. [PMID: 38302319 DOI: 10.1016/j.jpurol.2024.01.018] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 10/20/2023] [Revised: 12/19/2023] [Accepted: 01/17/2024] [Indexed: 02/03/2024]
Abstract
INTRODUCTION Pediatric patients with lower urinary tract dysfunction (LUTD) experience a variety of medical and psychosocial concerns that can negatively impact their clinical management and quality of life. When initially described by Drs Hinman and Baumann, patients with a form of severe LUTD, later dubbed Hinman syndrome, were characterized as having a "general attitude of being failures." While this mention was noteworthy as it incorporated an understanding of the interplay between psychological factors and urologic conditions, there have been delays in implementing psychological intervention as a standard of care in patients with LUTD broadly, and perhaps too keen of a focus on youth diagnosed with Hinman syndrome specifically. METHODS A non-systematic reviewed of LUTD related to psychological management was performed. Clinical recommendations were developed by a multicenter and multidisciplinary team of care providers with topic expertise. OBJECTIVE The aim of this paper is to propose a systems thinking paradigm for how to involve psychology, or psychological principles, across the spectrum of patients with LUTD with the hope of improving attention to specific aspects of care that may improve clinical management. DISCUSSION Children across the spectrum of LUTD are likely to benefit from psychological interventions and would benefit from such involvement early on to mitigate the impact of psychosocial concerns on medical outcomes. Pediatric psychologists are well-suited to identify and provide individualized care to patients in greatest need of intervention, such as through pre-procedural preparedness, addressing non-adherence, and with the use of evidence-based, targeted mental health interventions. Psychologists are also apt at implementing interventions while taking into consideration the severity of LUTD, in the context of the patient's psychological, developmental, cultural, familial, and social determinants of health considerations. Youth with severe forms of LUTD, such as Hinman syndrome, likely exemplify the challenges of LUTD that benefit from multidisciplinary intervention. CONCLUSION Medical and psychological collaboration are key to ensuring symptom mitigation and emotional support for patients across the entire spectrum of LUTD.

Outcomes after dextranomer/hyaluronic acid bladder neck injection in patients with urethral incontinence following bladder neck repair. J Pediatr Urol 2023; 19:743-748. [PMID: 37596195 DOI: 10.1016/j.jpurol.2023.07.002] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/12/2022] [Revised: 06/27/2023] [Accepted: 07/03/2023] [Indexed: 08/20/2023]
Abstract
INTRODUCTION Many patients who undergo surgery for bladder neck (BN) incompetence may still experience incontinence postoperatively. Dextranomer/hyaluronic acid (Dx/HA) is widely used for endoscopic treatment of vesicoureteral reflux in children; however, few studies have reported its use in treating incontinence after BN surgery. OBJECTIVE The aim of this study was to evaluate outcomes after Dx/HA bladder neck injection in patients with persistent outlet incompetency following BN Repair. STUDY DESIGN We retrospectively reviewed patients at a single pediatric tertiary care center with history of prior bladder neck surgery and reported persistent incontinence who then underwent endoscopic bladder neck Dx/HA injection from 2013 to 2018 and had subsequent follow-up post-injection. We described primary outcomes of reported incontinence as "wet" (leakage similar to before injection), "improved" (wet but leakage improved), and "dry" (no leakage). Our secondary outcome was need for a secondary procedure after Dx/HA injection, including Dx/HA injection or bladder neck closure (BNC). RESULTS At first follow-up (median 2.3 months post-op), 7/19 were wet, 6/19 were improved, and 6/19 were dry. At last follow-up (median of 34.7 months), only three patients (16%) were dry. Only one patient who received a single surgery for Dx/HA injection was "dry", though nearly 2/3rds (12) were initially "improved" in their continence. Overall, seven patients had another intervention or surgery after first injection. Five patients had multiple Dx/HA injections after first procedure, which resulted in dryness by last assessment in two of these. Four patients (21%) in the overall cohort required subsequent BNC. DISCUSSION Longer-term follow-up in our study demonstrated that only one patient who received a single procedure of Dx/HA injection remained dry. Several studies had follow up for greater than 1 year after initial bladder neck Dx/HA injection; rates of dryness after a single surgery for injection were variable and reported between 20 and 40% over follow-up times ranging from 1.5 to 7 years (Alova et al., 2012; DaJusta et al., 2013; Lottmann et al., 2006a; Lottmann et al., 2006b; Kitchens et al., 2007). Our st udy does have inherent limitations. This study was performed at a single institution in a retrospective manner, with a single surgeon reviewing the medical record to determine operative techniques and continence outcomes. The patient population is small, although relatively comparable to other previously reported studies. Outcomes were based on documentation of patient reports and are therefore lacking in objectivity. CONCLUSION In patients with prior unsuccessful BN repair, long-lasting dryness after single Dx/HA BN injection is unlikely, although one-third may demonstrate relatively durable improvement in incontinence.

Caregiver disclosure of common early childhood pediatric urologic surgeries. J Pediatr Urol 2023; 19:522.e1-522.e8. [PMID: 36898864 DOI: 10.1016/j.jpurol.2023.02.012] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/30/2022] [Revised: 02/16/2023] [Accepted: 02/19/2023] [Indexed: 02/25/2023]
Abstract
BACKGROUND Certain pediatric urologic diagnoses can have serious long-term adverse health outcomes. As a result, it is important for a child to be aware of their diagnosis and a prior surgery. When children have surgery prior to the age of memory formation, it is incumbent upon their caregiver to disclose this surgery. When and how to disclose this information and even if this occurs, is not clear. OBJECTIVE We developed a survey to assess caregiver plans to disclose early childhood pediatric urologic surgery and evaluate for predictors of disclosure and resources needed. METHODS A questionnaire was distributed to caregivers of male children ≤4 years old undergoing single stage repair of hypospadias, inguinal hernia, chordee, or cryptorchidism as part of an IRB approved research study. These surgeries were chosen due to being outpatient surgeries with potential long-term complications and impact. The age criteria was chosen due to likely being before patient memory formation and thus reliance on caregiver disclosure of prior surgery. Surveys were collected the day of surgery and contained information on caregiver demographics, validated health literacy screening, and plans to disclose surgery. RESULTS 120 survey responses were collected (Summary Table). The majority of caregivers responded affirmatively to planning to disclose their child's surgery (108; 90%). There was no impact of caregiver age, gender, race, marital status, education level, health literacy, or personal surgical history on plans to disclose surgery (p ≥ 0.05). Plan to disclose was also not different across urologic surgery type. Race was significantly associated with being "concerned or nervous about disclosing the surgery to the patient". The median patient age for planned disclosure was 10 years (IQR: 7-13). Only 17 respondents (14%) stated they received any information about how to discuss this surgery with the patient, however 83 (69%) felt this information would be helpful. CONCLUSIONS Our study suggests that most caregivers plan to discuss early childhood urologic surgeries with children, however want further guidance in how to talk to their child. While no specific surgery or demographic factor was found to be significantly associated with plans to disclose surgery, it is concerning that one in ten patients will potentially never learn about impactful surgery they had as a child. There is an opportunity for us to better counsel our patients' families about surgical disclosure and fill this gap with quality improvement efforts.

The December Effect in Pediatric Elective Surgery Utilization: Differences Between Privately and Publicly Insured Children. J Pediatr 2023; 253:213-218.e11. [PMID: 36202235 DOI: 10.1016/j.jpeds.2022.09.045] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/05/2022] [Revised: 09/23/2022] [Accepted: 09/28/2022] [Indexed: 11/13/2022]
Abstract
OBJECTIVES The objective of this study was to identify differences in December elective surgery utilization between privately and publicly insured children, given that increases in the prevalence and size of annual deductibles may be driving more families with commercial health insurance to delay elective pediatric surgical procedures until later in the calendar year. STUDY DESIGN We identified patients aged <18 years who underwent myringotomy, tonsillectomy ± adenoidectomy, tympanoplasty, hydrocelectomy, orchidopexy, distal hypospadias repair, or repair of inguinal, umbilical, or epigastric hernia using the 2012-2019 state inpatient and ambulatory surgery and services databases of 9 states. Log-binomial regression models were used to compare relative probabilities of procedures being performed each month. Linear regression models were used to evaluate temporal trends in the proportions of procedures performed in December. RESULTS Our study cohort (n = 1 001 728) consisted of 56.7% privately insured and 41.8% publicly insured children. Peak procedure utilization among privately and publicly insured children was in December (10.1%) and June (9.6%), respectively. Privately insured children were 24% (95% CI 22%-26%) more likely to undergo surgery in December (P < .001), with a significant increase seen for 8 of 9 procedures. There was no trend over time in the percentage of procedures performed in December, except for hydrocelectomies, which increased by 0.4 percentage points/year among privately insured children (P = .02). CONCLUSIONS Privately insured children are >20% more likely than publicly insured children to undergo elective surgery in December. However, despite increases in the prevalence of high deductibles, the proportion of procedures performed in December has not increased over recent years.

Reducing Opioid Prescriptions after Common Outpatient Pediatric Urologic Surgeries: A Quality Improvement Assessment. Pediatr Qual Saf 2023; 8:e623. [PMID: 36698439 PMCID: PMC9845012 DOI: 10.1097/pq9.0000000000000623] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/22/2022] [Accepted: 12/12/2022] [Indexed: 01/27/2023] Open
Abstract
Pediatric patients undergoing outpatient surgeries often receive prescriptions for postoperative pain, including opioid medications. As a result, the American Academy of Pediatrics formally challenged all pediatric surgeons to decrease opioid prescribing for common specialty-specific outpatient procedures at discharge. To meet this challenge, we designed a quality improvement project to decrease the average number of opioid doses administered to pediatric patients undergoing 3 common outpatient urologic surgeries: circumcision, orchiopexy, and inguinal hernia repair (IHR). Methods We formally challenged providers at our institution to reduce opioid doses per prescription and administration to patients overall. We performed a retrospective chart review at our single pediatric institution to establish baseline opioid prescribing values from July 2017 to March 2018. We aimed to reduce this value by 50% in 6 months and sustain this decrease throughout the project duration. Results We performed 1,518 orchiopexies, 1,505 circumcisions, and 531 IHRs. The percent change in the average number of opioid doses prescribed per patient from baseline values assessed to 2021 was statistically significant for orchiopexies (P < 0.0001), IHRs (P < 0.0001), and circumcisions (P < 0.0001). In addition, the change in the percentage of patients prescribed opioids from baseline was statistically significant for all 3 procedures (P < 0.001). Conclusions This project demonstrated that through an organized quality improvement initiative, the average number of opioid medications prescribed and the total percentage of patients prescribed opioids following common outpatient pediatric urologic procedures can be decreased by at least 50% and sustained through project duration.

A survey of pediatric urology fellowship applicants: past priorities to guide future possibilities. J Pediatr Urol 2022; 18:787.e1-787.e8. [PMID: 35780044 DOI: 10.1016/j.jpurol.2022.06.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/17/2022] [Revised: 06/02/2022] [Accepted: 06/14/2022] [Indexed: 10/18/2022]
Abstract
BACKGROUND The number of applicants to pediatric urology fellowships is often lower than the available positions (chart), giving applicants significant influence over where they ultimately match. Historically, interviews were conducted at individual hospitals, in-person, with residents bearing most costs. The objective of this study was to understand the factors associated with where applicants decide to apply, interview, and match for fellowship, as well as barriers within this process. METHODS A 24-question survey was sent via email to all applicants who successfully matched into pediatric urology fellowship from 2013 to 2019. Questions included: demographics; factors associated with where they applied, interviewed, and ranked; and barriers within the application process. RESULTS A total of 126 recent and current fellows were contacted, and 73 (60%) completed the full survey (51% male and 49% female). On average, respondents applied to 10 programs, interviewed at 9, and ranked 8. The most important factors in choosing where to apply/interview were: volume of surgical cases, diversity of surgical cases, and advice from mentors. The most important factors when making a rank list were: clinical autonomy, reputation of program, and structure of program. Hospital facilities were only rated "important" by 12% of respondents. 82% (60 respondents) faced at least one personal or professional barrier during the application process. The most common barrier was "cost of interviewing" (59%, 43 respondents). Personal vacation time was used by 61% of applicants during interviews, with 37% using more than 5 days. DISCUSSION This study is the first to explore the factors that applicants consider when choosing where to apply, interview, and rank for pediatric urology fellowship. This information is important to understand due to the current supply and demand of fellowship positions. We are limited by extrapolating more general conclusions about applicants as a whole from a survey with a 60% response rate and the lack of an available validated survey in this realm. CONCLUSIONS This study has shown that most pediatric urology fellowship applicants apply to programs primarily based on perceived surgical volume and reputational factors. These same factors are used when making a rank list. Many applicants faced personal or professional barriers during the application process, largely due to costs and time away from work and family. While recent interviews have transitioned to a virtual format by necessity, prior applicants did not rate hospital facilities as important to them. Overall, there is room to improve this process based on such feedback.

An online Sexual Health and Rehabilitation eClinic (TrueNTH SHAReClinic) for prostate cancer patients: a feasibility study. Support Care Cancer 2021; 30:1253-1260. [PMID: 34463836 PMCID: PMC8407130 DOI: 10.1007/s00520-021-06510-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 08/15/2021] [Indexed: 11/29/2022]
Abstract
Purpose The primary objective was to determine the feasibility of implementing the TrueNTH SHAReClinic as a pan-Canadian sexual health and rehabilitation intervention for patients treated for localized prostate cancer. Methods The feasibility study was designed to evaluate the accessibility and acceptability of the intervention. Participants from five institutions across Canada were enrolled to attend one pre-treatment and five follow-up online clinic visits over 1 year following their prostate cancer (PC) treatment. Results Sixty-five patients were enrolled in the intervention. Website analytics revealed that 71% completed the intervention in its entirety, including the educational modules, with an additional 10% completing more than half of the intervention. Five thousand eighty-three views of the educational modules were made along with 654 views of the health library items. Over 1500 messages were exchanged between participants and their sexual health coaches. At 12 months, the intervention received an overall average participant rating of 4.1 out of 5 on a single item satisfaction measure. Conclusion Results support the TrueNTH SHAReClinic as highly acceptable to participants as defined by intervention adherence and engagement. The TrueNTH SHAReClinic demonstrated promise for being a feasible and potentially resource-efficient approach to effectively improving the sexual well-being of patients after PC treatment.

Impact of successful pediatric ureteropelvic junction obstruction surgery on urinary HIP/PAP and BD-1 levels. J Pediatr Urol 2020; 16:592.e1-592.e7.

Abstract
INTRODUCTION In the pediatric patient whose ureteropelvic junction obstruction (UPJO) is not always symptomatic, imaging is the most common means of detecting surgical success. There is interest, however, in other means of post-operative monitoring. A panel of antimicrobial peptides (AMPs) has been previously found to be elevated in UPJO, but the impact of surgical correction on these AMPs is unknown. OBJECTIVE To determine if elevated levels of candidate urinary AMP biomarkers of urinary tract obstruction decrease following UPJO repair. STUDY DESIGN Pediatric patients undergoing surgical correction of an UPJO were recruited for participation. Bladder urine from uninfected consenting/assenting patients was collected immediately prior to surgery and then at least 6 months afterward. Based on prior studies demonstrating significant elevation of beta defensin 1 (BD-1), hepatocarcinoma-intestine-pancreas/pancreatitis-associated protein (HIP/PAP), cathelicidin (LL-37), and neutrophil gelatinase-associated lipocalin (NGAL) in patients with UPJO versus control patients, we performed enzyme-linked immunosorbent assays on these four AMPs to compare their expression before and after surgical intervention. If found to significantly decrease, AMP levels were compared to healthy controls. AMP levels were normalized to urine creatinine. Results were analyzed with paired t test or Wilcoxon test using Graphpad software. Correlation was calculated using Pearson or Spearman correlation. A p-value of <0.05 was considered significant. RESULTS 13 UPJO patients were included in this study; 9 were male (69%). Age at surgery was a median of 4.3 years (average 6.1, range 0.4-18.4 years). Follow-up urine samples were collected a median of 27.4 months after surgery (average 27.4; range 7.8-45.3 months). All 13 patients had clinical improvement and/or signs of improved hydronephrosis on post-operative imaging. HIP/PAP and BD-1 significantly decreased in post-surgical samples compared to pre-surgical samples (p = 0.02 and 0.01, respectively); NGAL and LL-37 did not significantly change. Overall, HIP/PAP decreased in 12 patients (92%) and BD-1 decreased in 11 patients (85%). BD-1 levels after successful repair were not different from healthy controls (p = 0.06). DISCUSSION Urinary biomarkers of obstruction should detect significant obstructive pathology as well as reflect its resolution. This would enable their use in post-operative monitoring and augment current methods of determining successful surgical outcome through imaging. CONCLUSIONS The AMPs HIP/PAP and BD-1 are significantly elevated in UPJO but then significantly decrease after pyeloplasty, with BD-1 returning to healthy control levels. As a result, these AMPs could serve as markers of successful surgical intervention.

Abstract
Evidence suggests multiple anesthetics in early childhood may increase risk for neurodevelopmental injury. We evaluated proportions of children undergoing circumcision and myringotomy, concomitantly with or prior to circumcision, and compared costs between groups. The Pediatric Health Information System was queried for males aged 6 to 36 months who underwent circumcision in 2009-2014. Relative to circumcision, the proportion who underwent myringotomy previously, concomitantly, or both, was calculated. Of 29 789 patients who underwent circumcision, 822 also underwent myringotomy; 342 (41.6%) underwent myringotomy on a previous day, and 480 (58.4%) underwent myringotomy at time of circumcision. Total hospital costs were lower for concomitant procedures (median $2994 vs $4609, P < .001. In total, 58.4% of patients who underwent circumcision and myringotomy did so concomitantly. Combined procedures resulted in significantly reduced costs and potentially minimized neurocognitive risk. Ideally, both referring pediatricians and surgical specialists should inquire about other surgical needs to optimize the availability of concomitant procedures.

Indicators and outcomes of transfer to tertiary pediatric hospitals for patients with testicular torsion. J Pediatr Urol 2017; 13:388.e1-388.e6.

Abstract
INTRODUCTION Testicular torsion threatens testicular viability with increased risk of loss with delayed management. Still, healthy adolescents continue to be transferred from community hospitals to tertiary hospitals for surgical management for torsion even though adult urologists may be available. We sought to determine reasons behind patient transfer and to evaluate whether transfer to tertiary centers for testicular torsion leads to increased rates of testicular loss. MATERIALS AND METHODS A retrospective chart review was performed for patients presenting to our free-standing pediatric tertiary care facility with surgically confirmed testicular torsion during the 5-year period between January 2011 and January 2016. Data was collected regarding transfer status, patient demographics, time of presentation to our facility, duration of symptoms, patient workup, and surgical outcomes. Patients with perinatal or intermittent torsion were excluded. RESULTS One-hundred and twenty-five patients met the inclusion criteria. Thirty-six of those were transferred from outside facilities while 89 presented directly to our hospital. A greater proportion of the transferred patients presented during nights or weekends than those presenting directly to our facility (77.8% versus 51.7%, p = 0.009). Eighty-nine patients presented with symptom duration of less than 24 h and had potentially viable testicles. Of those, 23 were transferred and 66 presented directly to our hospital. Differences are shown in the Table. Transferred patients had twice the rate of testicular loss as those not transferred, although the results were not significant (30.4% versus 15.2%, p = 0.129). Patients undergoing ultrasound prior to transfer had prolonged symptom duration and faced higher rates of testicular loss when compared with patients not transferred, although the latter was not significant (mean duration 8.0 versus 4.9 h, p = 0.025, and testicular loss 40.0% versus 15.2%, p = 0.065, respectively). Patients transferred over 30 miles had over 2.5 times the rate of testicular loss than those not transferred (42.8% versus 15.2%, p = 0.029). DISCUSSION This study is unique in its examination of motivations for transfer of patients presenting with testicular torsion and in its evaluation of the impact of transfer on testicular salvage rates for potentially viable testicles (those with less than 24 h since symptom onset). CONCLUSION Patients are more likely to be transferred to our tertiary pediatric facility for management of testicular torsion during the night or weekend. Transferring patients for management of testicular torsion delays definitive management and threatens testicular viability, especially in those transferred greater distances. Urologists at the facility of initial patient presentation should correct testicular torsion when able.

Abstract
Xanthogranulomatous cystitis (XC) is a rare condition affecting the bladder thought to be caused by chronic inflammation. Fewer than 30 cases have been reported in the literature since being first described in 1932. We present the first reported case of XC in a pre-pubertal male and review the literature. A 10-year-old boy presenting with dysuria subsequently developed frequency. After failure of conservative management, an ultrasound of the bladder revealed a mass. The patient underwent partial cystectomy. Pathology showed XC. At 10 months postoperatively, the patient remained asymptomatic and without evidence of recurrence.

Abstract
BACKGROUND Published reports of outcomes of robot assisted laparoscopic ureteral reimplantation (RALUR) show mixed results that, on average, are inferior to open ureteral reimplant. We present a retrospective analysis of a prospective series of children who had RALUR from 2013 to June 2015. We hypothesized that surgical outcomes are based on identifiable risk variables. We provide a critical analysis of the relationship between patient characteristics and several surgical and non-surgical outcomes. METHODS We reviewed the records of children who had Robot-Assisted Laparoscopic (RAL) Ureteral Reimplant (UR) at Nationwide Children's Hospital. Patient age and gender, preoperative presentation, presence of preoperative bladder and bowel dysfunction (BBD), VUR grade and laterality, indication for operation, operative time, surgical outcome, surgical complications, post-operative prevalence of UTI, and pre- and post-operative status of BBD were recorded. We also recorded techniques for ureteral dissection, and closing the detrusorrhaphy. Surgical outcome was defined by post-operative VCUG. We define BBD based on publications by the standardization committee of International Children's Continence Society (ICCS). All statistical calculations were performed with STATA version 11. RESULTS We performed extravesical RALUR on 54 children for a total of 72 ureters. Overall the study children were 74% female. The mean and median age was 5.2 and 4.9 years, respectively. Mean overall hospital length of stay (LOS) was 1.64 days. The mean LOS was 1.26 for unilateral (RALUUR) and 2.39 days for bilateral (RALBUR) surgeries and was significant (p < 0.05). Overall surgical success was 85.2% of ureters and 84.7% of children. Stratified by unilateral and bilateral surgeries, unilateral success was 91.7%, and bilateral success was 77.8% of ureters, and 72.2% of children. In the 3 failures in the RALUUR group the mean postoperative VUR grade was 1.3 from a pre-op mean grade of 3.3, whereas in the RALBUR group, the mean VUR grade among the failures was 3.0 from a mean pre-op VUR grade of 3.7. Urinary leak from ureteral injury, and urinary obstruction were more common in the RALBUR group. Post-operative urinary retention occurred in 4 children in the RALBUR and none in the RALUUR groups. Four with VUR after RALBUR and one child after RALUUR had open ureteral reimplant. Post-op UTI and non-surgical readmissions were higher in the RALBUR group. CONCLUSIONS Bilateral RALUR is associated with higher failure rates, higher complication rates, higher re-operation rates, and more postoperative UTIs and nonsurgical readmissions compared with unilaterasl RALUR.

Segmental arterial mapping during pediatric robot-assisted laparoscopic heminephrectomy: A descriptive series. J Pediatr Urol 2016; 12:266.e1-6. [PMID: 27321559 DOI: 10.1016/j.jpurol.2016.04.021] [Citation(s) in RCA: 27] [Impact Index Per Article: 3.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/12/2016] [Accepted: 04/30/2016] [Indexed: 01/08/2023]
Abstract
INTRODUCTION The incidence of innocent moiety injury during heminephrectomy is estimated to be 4-5%. This complication can have long-term consequences for the child. Selective arterial mapping (SAM) with indocyanine green (ICG)-aided near infrared fluorescence (NIRF) imaging using the Firefly™ system on the da Vinci(®) surgical robotic console has proven to be valuable in robotic partial nephrectomy for adult renal tumors. However, there is nothing in the literature for using this technique in pediatric robot-assisted laparoscopic heminephrectomy (RALHN). OBJECTIVE To present a descriptive series of children who had SAM RALHN using ICG-aided NIRF imaging. To determine the feasibility of using ICG-aided NIRF SAM during RALHN, and to study if real-time delineation of the selective arterial anatomy of the upper and lower moieties would be helpful or change the immediate outcomes of the surgery. STUDY DESIGN A descriptive series of six children who received RALHN at the present institution. RESULTS Selective arterial mapping was performed safely without toxicity or vascular complications; it did not extend the operative time and did not change the complexity of the operation. As shown in the summary table below, SAM added value by increasing safety of the operation. The individual operation cost increase of using SAM was only related to the single-use vial of ICG. DISCUSSION Inadvertent injury to the innocent moiety in pediatric heminephrectomy is seldom noted intraoperatively, and many times only becomes evident postoperatively when there is acute ischemia or a chronic reduction in renal function. Although there is no replacement for good surgical technique and judgment, SAM during RALHN is a useful real-time way of alerting the surgeon to unexpected anatomy, and possible unintended or occult injury to the innocent moiety that could have devastating short-term and long-term consequences to the child, despite immediate recovery from surgery. CONCLUSIONS This report achieved its aim of reporting the feasibility of SAM on a small descriptive series of children who had RALHN.

Robot-assisted laparoscopic management of duplex renal anomaly: Comparison of surgical outcomes to traditional pure laparoscopic and open surgery. J Pediatr Urol 2016; 12:44.e1-7. [PMID: 26443241 DOI: 10.1016/j.jpurol.2015.04.046] [Citation(s) in RCA: 33] [Impact Index Per Article: 4.1] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/22/2014] [Accepted: 04/14/2015] [Indexed: 11/15/2022]
Abstract
INTRODUCTION Surgical management of duplex renal anomaly (DRA) is complex because of individual anatomic variation, competing priorities of vesicoureteral reflux (VUR) and ureteral obstruction present in the same child, the varied differential function of the different renal moieties, and the presence of voiding dysfunction and recurrent urinary tract infection (UTI). Robot-assisted laparoscopic (RAL) surgical management has been under-reported in this group of children but is becoming a viable alternative to traditional open surgery. OBJECTIVE The aim was to report the surgical outcomes of a series of children with DRA who had RAL surgery and compare these outcomes to historical cohorts of open and laparoscopic surgery. STUDY DESIGN This was a retrospective analysis of a prospective series of children who had RAL surgery for DRA over an 8-year period. Forty-five RAL surgeries were performed in 47 children. RAL heminephrectomy (RAL HN) was performed in 19 children for poorly or non-functional renal moiety. One had staged bilateral RAL HN. RAL ureteroureterostomy (RAL UU) was performed in 14 children for upper pole ureteral obstruction. Thirteen RAL common sheath ureteral reimplants (RAL csUN) with or without ureteral tapering were performed in 12 children with VUR and UTI. Diagnosis and demographics, results of preoperative imaging, intraoperative time stamps, perioperative complications, success rate, and renal outcomes were recorded. RESULTS Low-grade VUR present preoperatively in the RAL UU group all resolved within the follow-up period. Four (25%) children in the RAL HN group developed de novo VUR after surgery, which resolved in two (50%) and required surgery in two (50%). Grade I VUR after RAL csUR that occurred in two (14.3%) children was asymptomatic and observed when off preventative antibiotics. DISCUSSION Most children with DRA who need surgical treatment can be offered RAL surgery. We report good outcomes and improved operative times for RAL HN and UU that approach historical open and pure laparoscopic cohorts. However, RAL csUR, especially with ureteral tapering, is more complex and inherently susceptible to complications, and has not met the outcomes of the open gold standard. The limits of this study are that selection bias is present, and there is no study control cohort. CONCLUSIONS This report achieves its aim to report surgical outcomes of children who had RAL surgery for DRA.

PNPLA3 rs738409 I748M is associated with steatohepatitis in 434 non-obese subjects with hepatitis C. Aliment Pharmacol Ther 2015; 41:939-48. [PMID: 25801076 DOI: 10.1111/apt.13169] [Citation(s) in RCA: 17] [Impact Index Per Article: 1.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/29/2014] [Revised: 01/28/2015] [Accepted: 03/02/2015] [Indexed: 12/18/2022]
Abstract
BACKGROUND The PNPLA3/Adiponutrin rs738409 C/G single nucleotide polymorphism is associated with the severity of steatosis, steatohepatitis and fibrosis in patients with non-alcoholic fatty liver disease, as well as the severity of steatosis and fibrosis in patients with chronic hepatitis C (CHC). AIM To test in genotype 1(G1)-CHC patients, the putative association between the PNPLA3 variant and histological features of steatohepatitis, as well as their impact on the severity of fibrosis. METHODS Four hundred and thirty-four consecutively biopsied Caucasian G1-CHC patients were genotyped for PNPLA3 rs738409, its effect evaluated by using an additive model. Histological features of steatohepatitis in CHC were assessed using the Bedossa classification. Hepatic expression of PNPLA3 mRNA was evaluated in 63 patients. RESULTS The prevalence of steatohepatitis increased from 16.5% in patients with PNPLA3 CC, to 23.2% in CG and 29.2% in the GG genotype (P = 0.02). By multiple logistic regression, PNPLA3 genotype (OR 1.54, 95% CI 1.03-2.30, P = 0.03), together with age (OR 1.03, 95% CI 1.00-1.05, P = 0.02), BMI ≥ 30 (OR 2.06, 95% CI 1.04-4.10, P = 0.03) and homoeostasis model assessment (HOMA, OR 1.18, 95% CI 1.04-1.32, P = 0.006) were independently linked to steatohepatitis. When stratifying for obesity, PNPLA3 was associated with NASH in non-obese patients only (12.0% in CC vs. 18.3% in CG vs. 27.3% in GG, P = 0.01), including after correction for metabolic confounders (OR 2.06, 95% CI 1.26-3.36, P = 0.004). We showed an independent association between steatohepatitis (OR 2.05, 95% CI 1.05-4.02, P = 0.003) and severe fibrosis. Higher liver PNPLA3 mRNA was associated both with the severity of steatosis (adjusted P = 0.03) and steatohepatitis after adjusting for gender, age, BMI and HOMA (P = 0.002). CONCLUSION In patients with genotype 1 hepatitis C, the PNPLA3 G variant is associated with a higher risk of steatosis severity and steatohepatitis, particularly among non-obese subjects.

Abstract
OBJECTIVE Our study aims to evaluate variations in management of asymptomatic adolescent grade 2 and 3 varicoceles by pediatric urologists. SUBJECTS AND METHODS Electronic survey of all 267 current members of AAP Urology with 74 (28%) responding. RESULTS When managing patients with positive examination findings, 49% of surveyed practitioners use scrotal sonography as initial screening, while 38% use only manual orchidometry and 11% observation with serial examinations. If significant testicular size discrepancy is identified, 32% immediately intervene surgically, while 59% repeat measurements in 6-12 months. When no discrepancy is identified, 36.6% of practitioners discharge their patients with no follow-up, 22.5% refer to an infertility specialist, and 31% evaluate with semen analysis. Fifty-seven percent of practitioners have never sent patients for semen analysis; only 4% send >50% of patients. Of these, 52% and 27% analyzed semen at 17-18 years and 19-20 years, respectively, and 10% send for semen analysis at <17 years. CONCLUSIONS Our survey demonstrates that there does not appear to be a consensus among pediatric urologists managing asymptomatic grade 2 and 3 varicoceles. Better understanding of which adolescent patients with varicoceles will go on to develop male infertility is necessary to identify pediatric patients who could benefit from early intervention.

Abstract
Couplelinks is an original, professionally facilitated online intervention tailored to the unique challenges facing young women with breast cancer and their male partners. The purpose of this evaluation was to determine the feasibility and acceptability of the intervention and areas for improvement. Sixteen couples were sequentially enrolled over an 18-month period. Couples provided feedback via a treatment satisfaction survey, and post-treatment interviews with a sub-group of participants. Qualitative information was analysed for themes relevant to the program's acceptability, perceived benefits and limitations, and directions for improvement. Of the 16 couples who enrolled, six completed four modules or less, and 10 completed the entire program. Completers reported satisfaction with the program overall, as well as with the website useability and professional facilitation. Reported benefits were: enhanced communication and self-other knowledge; creation of opportunities for meaningful, cancer-related discussion; affirmation of relationship strengths; and a greater sense of closeness between partners. The main reported limitation was how program participation disrupted the couple's usual routine. Themes related to non-completion suggest that partners with particularly elevated relational or illness-related distress, or with differential levels of motivation, are less likely to finish. These findings have led to targeted improvements to the website and intervention protocol.

Abstract
PURPOSE The purpose of the present systematic review was to develop a practice guideline to inform health care providers about screening, assessment, and effective management of cancer-related fatigue (crf) in adults. METHODS The internationally endorsed adapte methodology was used to develop a practice guideline for pan-Canadian use. A systematic search of the literature identified a broad range of evidence: clinical practice guidelines, systematic reviews, and other guidance documents on the screening, assessment, and management of crf. The search included medline, embase, cinahl, the Cochrane Library, and other guideline and data sources to December 2009. RESULTS Two clinical practice guidelines were identified for adaptation. Seven guidance documents and four systematic reviews also provided supplementary evidence to inform guideline recommendations. Health professionals across Canada provided expert feedback on the adapted recommendations in the practice guideline and algorithm through a participatory external review process. CONCLUSIONS Practice guidelines can facilitate the adoption of evidence-based assessment and interventions for adult cancer patients experiencing fatigue. Development of an algorithm to guide decision-making in practice may also foster the uptake of a guideline into routine care.

Abstract
Canada is a pioneer in remote cancer care delivery to underserved populations; however, it is trailing behind on policies that would support clinicians in providing care using distance technologies. The current policy framework is disjointed, and discussions by professional boards about online jurisprudence associated with licensure appear to be regressive. We hope that by addressing the discrepancies in interjurisdictional practice and focusing on the key issue of "where therapy resides," we will be able to nudge dialogue and thinking closer toward the reasoning and recommendations of national telehealth organizations. We present this discussion of jurisdictional issues and e-health practice in the context of a pan-Canadian online support program developed for cancer patients and family members. Although the present paper uses online support groups as a springboard to advocate for e-health, it ultimately addresses a broader audience: that of all Canadian health care stakeholders.

Abstract
Approximately 22,700 Canadian women were expected to be diagnosed with breast cancer in 2012. Despite improvements in screening and adjuvant treatment options, a substantial number of postmenopausal women with hormone receptor positive (hr+) breast cancer will continue to develop metastatic disease during or after adjuvant endocrine therapy. Guidance on the selection of endocrine therapy for patients with hr+ disease that is negative for the human epidermal growth factor receptor 2 (her2-) and that has relapsed or progressed on earlier nonsteroidal aromatase inhibitor (nsai) therapy is of increasing clinical importance. Exemestane, fulvestrant, and tamoxifen are approved therapeutic options in this context. Four phase iii trials involving 2876 patients-efect, sofea, confirm, and bolero-2-have assessed the efficacy of various treatment options in this clinical setting. Data from those trials suggest that standard-dose fulvestrant (250 mg monthly) and exemestane are of comparable efficacy, that doubling the dose of fulvestrant from 250 mg to 500 mg monthly results in a 15% reduction in the risk of progression, and that adding everolimus to exemestane (compared with exemestane alone) results in a 57% reduction in the risk of progression, albeit with increased toxicity. Multiple treatment options are now available to women with hr+ her2- advanced breast cancer recurring or progressing on earlier nsai therapy, although current clinical trial data suggest more robust clinical efficacy with everolimus plus exemestane. Consideration should be given to the patient's age, functional status, and comorbidities during selection of an endocrine therapy, and use of a proactive everolimus safety management strategy is encouraged.

Abstract
BACKGROUND Professional-led cancer support groups can improve quality of life and address unmet needs, but most Canadians affected by cancer do not have access to or do not make use of cancer support groups. A collaborative interdisciplinary team developed, operated, and evaluated Internet-based, professional-led, live-chat support groups (osgs) for cancer patients, caregivers, and survivors across Canada. OBJECTIVE Our study aimed to report participant and participation characteristics in the pan-Canadian initiative known as CancerChatCanada, and to understand participant perspectives about the quality of communication and professional facilitation, overall satisfaction, and psychosocial benefits and outcomes. METHODS Participants in osgs provided informed consent. Participant and participation characteristics were gathered from program data collection tools and are described using frequencies, means, and chi-squares. Patient, survivor, and caregiver perspectives were derived from 102 telephone interviews conducted after osg completion and subjected to a directed qualitative content analysis. RESULTS The 55 professional-led osgs enrolled 351 participants from 9 provinces. More than half the participants came from rural or semirural areas, and more than 84% had no received previous cancer support. The attendance rate was 75%, the dropout rate was 26%, and 80% of participants were satisfied or very satisfied. The convenience and privacy of osgs were benefits. Meaningful communication about important and difficult topics, kinship and bonding with others, and improved mood and self-care were perceived outcomes. CONCLUSIONS Our results demonstrate that this collaborative initiative was successful in increasing reach and access, and that pan-Canadian, professional-led osgs provide psychosocial benefit to underserved and burdened cancer patients, survivors, and family caregivers.

Abstract
BACKGROUND Triple-negative breast cancer (TNBC) is a distinct subset of breast cancer (BC) defined by the lack of immunohistochemical expression of the estrogen and progesterone receptors and human epidermal growth factor receptor 2. It is highly heterogeneous and displays overlapping characteristics with both basal-like and BC susceptibility gene 1 and 2 mutant BCs. This review evaluates the activity of emerging targeted agents in TNBC. DESIGN A systematic review of PubMed and conference databases was carried out to identify randomised clinical trials reporting outcomes in women with TNBC treated with targeted and platinum-based therapies. RESULTS AND DISCUSSION Our review identified TNBC studies of agents with different mechanisms of action, including induction of synthetic lethality and inhibition of angiogenesis, growth, and survival pathways. Combining targeted agents with chemotherapy in TNBC produced only modest gains in progression-free survival, and had little impact on survival. Six TNBC subgroups have been identified and found to differentially respond to specific targeted agents. The use of biological preselection to guide therapy will improve therapeutic indices in target-bearing populations. CONCLUSION Ongoing clinical trials of targeted agents in unselected TNBC populations have yet to produce substantial improvements in outcomes, and advancements will depend on their development in target-selected populations.

Abstract
PURPOSE Although recommended as an essential part of cancer care, there is limited evidence regarding the optimum approach to psychosocial health care needs assessment in this setting. To address this gap, the Cancer Journey Action Group of the Canadian Partnership Against Cancer (CPAC) and the Canadian Association of Psychosocial Oncology (CAPO) partnered to develop consensus-based recommendations regarding the routine assessment of psychosocial and supportive care needs. The purpose of this paper is to summarize the evidence that informed the guideline and disseminate the recommendations developed by the expert panel. METHODS Clinical practice recommendations were developed by a panel comprised of psychosocial and interdisciplinary experts. Recommendations were informed by a review of oncology clinical practice guidelines, systematic reviews, and primary research, through to May 2008. Following expert consensus on the recommendations, the clinical practice guideline was externally reviewed by a purposively selected sample of national and international interdisciplinary experts. RESULTS A total of nine clinical practice guidelines, three systematic reviews, and 14 primary studies were included in the review. Overall, this body of literature suggested that routine collection of psychosocial health care data has an influence on communication with oncologists and other study specific outcomes, but the evidence was limited by heterogeneity and methodological limitations. Based on the interpretation of this body of evidence by clinical experts, research methodologists, and external reviewers, 12 substantive recommendations were developed regarding the process and parameters of psychosocial needs assessment in adult cancer patients. CONCLUSION Given the limitations in the current body of evidence, there remains a need for rigorous empirical research regarding the optimal approach to psychosocial needs assessment, including the specific characteristics that influence effectiveness on patient outcomes. This guideline fills an important gap in psychosocial care, regarding the routine assessment of psychosocial health care needs.

Abstract
BACKGROUND AND STUDY AIMS Complete Barrett's excision (CBE) of short-segment Barrett's high grade dysplasia (HGD) and early esophageal adenocarcinoma by stepwise endoscopic resection is a precise staging tool, detects covert synchronous disease, and may produce a sustained treatment response. Esophageal stricture is the most commonly reported complication of CBE although risk factors have not yet been clearly defined. PATIENTS AND METHODS Data were recorded prospectively on patients with limited co-morbidity and age ≤ 80 years undergoing CBE for histologically proven HGD or esophageal adenocarcinoma within ≤ C3M5 segments. Endoscopic resection was performed by standardized protocol every 6 - 8 weeks until CBE was achieved. Esophageal dilation was performed when patients reported dysphagia. Dysphagia scores were recorded at scheduled endoscopic surveillance or by telephone interview. RESULTS By intention-to-treat analysis, complete eradication of neoplasia and intestinal metaplasia was achieved in 95 % and 82 %, respectively, in 77 patients undergoing a median of 2 resection sessions (interquartile range [IQR] 1 - 3). Esophageal dilation was required in 33 % (median 3 dilations, IQR 1 - 3.5) at median follow-up of 20 months (IQR 6 - 40). Independent risk factors for dilation requirement were the number of mucosal resections at the index procedure (odds ratio [OR] 1.3 per resection, 95 % confidence interval [CI] 1.0 - 1.9; P = 0.043) and maximal extent of the Barrett's segment (OR 2.2 per cm, 95 %CI 1.2 - 3.9; P = 0.009). CONCLUSIONS Although CBE is highly effective in the treatment of Barrett's HGD and esophageal adenocarcinoma, the risk of post-CBE dysphagia increases with the maximal extent of the Barrett's segment and the number of mucosal resections at the index procedure. These data could be used to inform treatment decisions and identify those patients who may benefit from prophylactic therapies such as dilation.

Abstract
AIM Baroreflex control of the bronchial circulation is unresolved. Early studies suggested that baroreflexes dilate or have no effect, but recent studies in awake dogs suggested baroreflexes did not normally engage tonic vasoconstrictor efferents but during excitement systemic pressure rises may also trigger local sensory-motor dilator reflexes. We examined the postulate that bronchial flow is normally regulated at rest during controlled changes in pressure gradient (Pg) by integration of tonic autonomic activity with autoregulation. METHODS Twelve greyhounds were instrumented under general anaesthesia by surgical implantation of pulsed Doppler flow transducers on the right bronchial artery (BA). After recovery baroreflex effects were evoked by raising and lowering aortic pressure using a lower thoracic aortic balloon in 11 animals, and in six of these after cholinoceptor plus adrenoceptor blockade. RESULTS The right BA bed showed pressure-passive responses and the time-dependent bronchial bed effects in the autonomically intact state (INT) were largely similar to those in the blocked state (TAB). When results were replotted as pressure-flow relationships and analysed using covariance, the regression line over the pressure range 70-135 mmHg for TAB demonstrated a significant slope (P < 0.05), a linear regression elevated 120% (P = 0.006) above and parallel to INT (Y(Q) = 0.034 + 0.00033(X(Pg) - 104.6). The regression fell on the line of equal proportional change. CONCLUSION Baroreflexes do not functionally engage the autonomic outflow to the bronchial circulation. Under controlled conditions of systemic Pg change, the bronchial circulation is normally controlled by the integration of resting autonomic tone, myogenic autoregulation and pressure-passive effects.

Abstract
Abstract
Background: The Hh signalling pathway plays an important role in a number of malignancies, and accumulating data suggest it contributes significantly to the development and progression of breast cancer. However, there is scant data regarding the clinical significance of its dysregulation in breast cancer and its functional effects in breast cancer models.
Methods: We investigated the clinical significance of the expression of Hh pathway components using immunohistochemistry in a well-characterised cohort of 279 patients with invasive ductal carcinoma (IDC) to determine its prognostic significance. A murine mammary cancer allograft model based on the M6 cell line, derived from the C3/SV40T transgenic mouse was used to determine the effects of Shh overexpression on tumour growth in vitro and in vivo. Finally, the therapeutic potential of Hh blockade using the monoclonal antibody 5E1 was also explored in two mouse mammary carcinoma models; the M6 allograft model and the highly metastatic 4T1 cell line in immunocompetent Balb/C mice.
Results: High Hh ligand expression was observed in 34% of IDC and was associated with increased risk of breast cancer recurrence (HR 1.95, p=0.0004) and breast cancer specific death (HR 2.3, p=0.0002). High Hh expression was also associated with the basal-like subtype (p=0.004). Overexpression of Hh ligand in M6 cells transplanted to fat pads of immunodeficient mice resulted in a 4 fold increase in tumor volume (p= 0.006) and was associated with upregulation of the canonical Hh target genes Gli1 and HHIP. However, Shh promoted peritumoral lymphatic invasion in 4/5 mice compared to only 1/5 in the vector control group and was associated with a significantly shorter time to the development of metastatic disease (p=0.0004). M6 cells overexpressing Hh ligand showed no change in proliferation, self renewal or migration in vitro, suggesting a requirement for stromal interaction in Hh-dependent tumor promotion. Finally, we found that the enhanced tumor growth conferred by Hh ligand overexpression could be blocked by administration of a neutralizing antibody to Hh ligand. Furthermore, using a metastatic mammary carcinoma isograft model (4T1) that endogenously expresses Hh ligand, we demonstrate that Hh blockade resulted in smaller lung metastatic deposits (p=0.045).
Conclusions: We found that high Hh ligand is associated with a poor prognosis in IDC. Overexpression of Hh ligand promotes murine mammary tumor growth, which requires stromal interaction, as well as lymphatic vessel invasion. Finally, we demonstrate that blockade of the Hh ligand is a potential therapy in metastatic breast carcinoma.

Abstract
BACKGROUND AND STUDY AIMS Small flat nonpolypoid lesions of the colorectum can be technically difficult to target and completely remove; techniques such as hot biopsy forceps electrocauterization are associated with serositis, delayed bleeding, and perforation. This study aimed to describe a novel technique for the removal of such lesions and demonstrate its safety and efficacy. PATIENTS AND METHODS Patients aged 18 - 80 years with flat nonpolypoid lesions (Paris-Japanese classification 0-IIa and 0-IIb, measuring less than 10 mm) identified at colonoscopy were included in this prospective study. The lesions were removed by the suction pseudopolyp technique (SPT): the lesion is aspirated into the suction channel of the colonoscope and continuous suction applied for 5 seconds whilst the colonoscope is gently retracted. On release of the suction, the resulting pseudopolyp containing the lesion and a margin of normal tissue is easily ensnared and resected. The primary outcomes were endoscopic completeness of polyp resection and complication rate. RESULTS Over a 12-month period, 1231 polyps were removed during 2656 colonoscopies; 126 polyps (in 101 patients) met inclusion criteria. Complete endoscopic resection was achieved in 100 % of the polyps, without immediate or delayed complication. Of the resected lesions, 57 % had malignant potential (adenomas 47 % and sessile serrated lesions 10 %); a higher proportion of lesions removed from the right colon had malignant potential compared with those from the left colon (75 % vs. 41 %, P = 0.0066). CONCLUSIONS Diminutive flat lesions of the colorectum are predominantly adenomas and sessile serrated lesions. SPT is a safe, effective, and reproducible therapy for removal of these lesions.

Abstract
OBJECTIVES To describe the reference range for heart rate in children aged 3 months-10 years presenting to primary care with self-limiting infections. DESIGN Cross-sectional study of children presenting to primary care with suspected acute infection. Heart rate was measured using a pulse oximeter and axillary temperature using an electronic thermometer. Centile charts of heart rates expected at given temperatures for children with self-limiting infections were calculated. SETTING Ten general practice surgeries and two out-of-hours centres in England. PARTICIPANTS 1933 children presenting with suspected acute infections were recruited from in-hours general practice surgeries (1050 or 54.3%) or out-of-hours centres (883 or 45.7%). After excluding children who subsequently attended hospital and those without a final diagnosis of acute infection, 1589 children were used to create the centile charts of whom (859 or 54.1%) had upper respiratory tract infections and (215 or 13.5%) non-specific viral illness. MAIN OUTCOME MEASURES Median, 75th, 90th and 97th centiles of heart rate at each temperature level. RESULTS Heart rate increased by 9.9-14.1 bpm with each 1 degrees C increment in temperature. The 50th, 75th, 90th and 97th centiles of heart rate at each temperature level are presented graphically. CONCLUSIONS Age-specific centile charts of heart rates expected at different temperatures should be used by clinicians in the initial assessment of children with acute infections. The charts will identify children who have a heart rate higher than expected for a given temperature and facilitate the interpretation of changes in heart rate on reassessment. Further research on the predictive value of the centile charts is needed to optimise their diagnostic utility.
