Cloacal Exstrophy Closure Without Osteotomy and Immobilization: A Recipe for Failure.

Background: Cloacal exstrophy (CE) remains one of the most severe birth defects compatible with life with a constellation of anomalies involving the bladder, genitalia, hindgut, and spinal cord. Pelvic osteotomy and immobilization have been utilized to facilitate bladder closure, yet their role as adjuncts remains a topic of debate. The authors sought to evaluate the outcomes of CE closure without the use of osteotomy or lower extremity (LE)/pelvic immobilization.

Patients were randomized (1:1) to receive either the Food and Drug Administration (FDA) opioid disposal best practices worksheet plus nursing parental education or routine postoperative instructions alone.

A Rocky Road: Bladder Stones in the Augmented Exstrophy-Epispadias Complex Patient.

Objective: To determine the rate of stone formation amongst patients of the exstrophy-epispadias complex with augmentation cystoplasty. We hypothesize that bowel segment choice influences the rate of stone formation after bladder augmentation and the rate of complications from bladder stone surgery.

Methods: An IRB-approved institutional database of 1512 exstrophy-epispadias patients was reviewed retrospectively.

Stomal Stenosis After Continent Urinary Diversion in Bladder Exstrophy: Risk Factors and Management.

Objective: To identify risk factors for stenosis and compare management strategies for stenosis etiology and to examine the efficacy of each approach. Patients with classic bladder exstrophy (CBE), a rare genitourinary malformation, may require construction of a continent urinary stoma (CUS) if incontinence persists. Stomal stenosis is a challenging complication as it is common, progressive, and recurrent.

Variations in germ cell tumor histology by age and implications for cancer-specific survival among pediatric and adult males: A population-based study.

Purpose: Few studies have quantified differences in histology and implications for survival between male children and adults with germ cell tumors (GCT). We evaluated these differences and associations with cancer-specific survival (CSS) using Surveillance, Epidemiology, and End Results (SEER) cancer registries.

Methods: SEER (1988-2016) was used to identify male patients 0 to 40 years of age diagnosed with seminoma and nonseminomatous GCT (NSGCT).

Perioperative management of primary classic bladder exstrophy: A single institutional pathway to success.

Purpose: Appropriate perioperative management is crucial in patients undergoing classic bladder exstrophy closure (CBE). Therefore, the authors sought to review their intra and postoperative management of patients with CBE undergoing primary closure and examine the impact of this pathway on patient outcomes.

Method: A prospectively maintained institutional approved exstrophy-epispadias complex database was reviewed for patients with CBE who had undergone primary closure between 2016 and 2022 and whose closure was performed within one year of age.

Clinical patterns and implications of prescription opioid use in a pediatric population for the management of urolithiasis in the emergency room.

Extrapolations from the adult population have suggested that opioids should be avoided in the management of pediatric urolithiasis, but the literature is sparse with regards to actual practice patterns and the downstream implications. We sought to investigate the rate of oral opioid administration for children presenting to the emergency room (ER) with urolithiasis and to identify associations between opioid administration and return visits and persistent opioid use. The TriNetX Research and Diamond Networks were used for retrospective exploratory and validation analyses, respectively.

De novo variants identified by trio whole exome sequencing of bladder exstrophy epispadias complex.

Bladder exstrophy epispadias complex (BEEC) encompasses a spectrum of conditions ranging from mild epispadias to the most severe form: omphalocele-bladder exstrophy-imperforate anus-spinal defects (OEIS). BEEC involves abnormalities related to anatomical structures that are proposed to have a similar underlying etiology and pathogenesis. In general, BEEC, is considered to arise from a sequence of events in embryonic development and is believed to be a multi-etiological disease with contributions from genetic and environmental factors.

Purpose: We sought to determine if the addition of liposomal bupivacaine to bupivacaine hydrochloride improves opioid-free rate and postoperative pain scores among children undergoing ambulatory urologic surgery.

Materials And Methods: A prospective, phase 3, single-blinded, single-center randomized trial with superiority design was conducted in children 6 to 18 years undergoing ambulatory urologic procedures between October 2021 and April 2023. Patients were randomized 1:1 to receive dorsal penile nerve block (penile procedures) or incisional infiltration with spermatic cord block (inguinal/scrotal procedures) with weight-based liposomal bupivacaine plus bupivacaine hydrochloride or bupivacaine hydrochloride alone.

Preparation and characterization of NaF/Chitosan supramolecular complex and their effects on prevention of enamel demineralization.

Fluoridated mouthrinse is indicated for individuals with high risk of caries. Chitosan (Chit) exhibits antibacterial properties, but little is known about its effects on enamel when combined with sodium fluoride (NaF) to form NaF/Chit supramolecular complexes. In our study, NaF/Chit supramolecular complexes structured as microparticles were synthetized and characterized, and their effects on human enamel were evaluated after cariogenic challenge simulating the daily mouthrinse use.

Achieving goal capacity for continence surgery: A cumulative event analysis of bladder exstrophy patients.

Background: Following successful closure of patients with classic bladder exstrophy (CBE), the next major milestone is the establishment of urinary continence. Prior to determining the most appropriate continence surgery, it is imperative to reach an adequate bladder capacity minimum of 100 cc in order to make the decision between bladder neck reconstruction (BNR) or continent stoma, with or without augmentation cystoplasty (AC).

Objective: To examine the timing of when patients achieve threshold bladder capacity for BNR eligibility.

Bladder capacity and growth in classic bladder exstrophy: A novel predictive tool.

Introduction: Bladder capacity (BC) is an important metric in the management of patients with classic bladder exstrophy (CBE). BC is frequently used to determine eligibility for surgical continence procedures, such as bladder neck reconstruction (BNR), and is associated with the likelihood of achieving urinary continence.

Objective: To use readily available parameters to develop a nomogram that could be used by patients and pediatric urologists to predict BC in patients with CBE.

Translucency and Radiopacity of Dental Resin Composites - Is There a Direct Relation?

Objectives: The purpose of this study was to correlate the translucency degree of varying resin composites with their radiopacity.

Complications of delayed and newborn primary closures of classic bladder exstrophy: Is there a difference?

Introduction: The authors aim to compare single institutional 30-day complication rates between delayed and neonatal closure of classic bladder exstrophy (CBE).

Materials And Methods: An institutional database of 1415 exstrophy-epispadias patients was reviewed retrospectively for CBE patients who underwent primary closures at the authors' institution between 1990 and 2020. Patients were identified as having received either neonatal or delayed (at age >28 days) closures.

Abdominal Mass in a Phenotypic Female with 46,XY Differences in Sex Development.

We present a case of a large intra-abdominal mass found to be localized pure seminoma within a retained gonad of a 53-year-old phenotypic female with 46,XY differences in sex development (DSD) and androgen insensitivity syndrome (AIS). Our management included extirpation of the mass with contralateral gonadectomy. Historically, patients with AIS would undergo gonadectomy to mitigate the lifetime risk of testicular germ cell tumor development; however, growing evidence suggests safety in retention and surveillance of these gonads into adulthood.

Possible Relationship Between the Oral and Gut Microbiome, Caries Development, and Obesity in Children During the COVID-19 Pandemic.

The COVID-19 pandemic has brought health damage and socioeconomic disruptions, together with lifestyle disorders around the world. Children are one of the most commonly affected, mainly due to social isolation and changes in eating habits and physical activities. This way, the risk of weight gain and obesity is possibly enhanced, as well as poor oral hygiene conditions and early childhood caries (ECC) development during the lockdown.
