Automation of Wilms' tumor segmentation by artificial intelligence.

Background: 3D reconstruction of Wilms' tumor provides several advantages but are not systematically performed because manual segmentation is extremely time-consuming. The objective of our study was to develop an artificial intelligence tool to automate the segmentation of tumors and kidneys in children.

Methods: A manual segmentation was carried out by two experts on 14 CT scans.

Clinical Effectiveness of Transversus Abdominis Plane (TAP) Block versus Local Anesthesia Wound Infiltration for Postoperative Pain Relief After Laparoscopic Appendicectomy in Children: A Study Protocol for a Multicenter Double-Blind Randomized Controlled Phase III Trial.

Purpose: Postoperative pain relief after laparoscopic appendicectomy is a key determinant of early rehabilitation in children. Recent guidelines recommend performing either a transversus abdominis plane (TAP) block or local anesthesia (LA) wound infiltration as part of multimodal postoperative analgesia after appendectomy. To date, the clinical effectiveness of TAP block versus LA wound infiltration has never been compared.

Financial and relational impact of having a boy with posterior urethral valves.

Introduction: Childhood chronic diseases affect family functioning and well-being. The aim of this study was to measure the impact of caring for a child with PUV, and the factors that most impact the burden of care.

Patients And Method: We gave a questionnaire on the familial impact of having a child with posterior urethral valves to all parents of a child included in the CIRCUP trial from 2015 onwards.

Risk factors for febrile urinary tract infection in boys with posterior urethral valves.

Objective: Boys with posterior urethral valves (PUV) present an increased risk of febrile urinary tract infection (fUTI). Identifying specific risk factors could allow for tailoring UTI prevention. The aim of this study was to use the data from the CIRCUP randomized controlled trial data to identify patient characteristics associated with a higher risk of fUTI.

Nutritional status at age 1 year in patients born with esophageal atresia: A population-based, prospective cohort study.

Objective: Despite recent progress in caring for patients born with esophageal atresia (EA), undernutrition and stunting remain common. Our study objective was to assess nutritional status in the first year after birth with EA and to identify factors associated with growth failure.

Study Design: We conducted a population-based study of all infants born in France with EA between 2010 and 2016.

Lessons from a large nationwide cohort of 350 children with ovarian mature teratoma: A study in favor of ovarian-sparing surgery.

Background: Ovarian mature teratoma (OMT) is a common ovarian tumor found in the pediatric population. In 10%-20% of cases, OMT occurs as multiple synchronous or metachronous lesions on ipsi- or contralateral ovaries. Ovarian-sparing surgery (OSS) is recommended to preserve fertility, but total oophorectomy (TO) is still performed.

Esophageal Atresia and Respiratory Morbidity.

Background And Objectives: Respiratory diseases are common in children with esophageal atresia (EA), leading to increased morbidity and mortality in the first year. The primary study objective was to identify the factors associated with readmissions for respiratory causes in the first year in EA children.

Methods: A population-based study.

Risk Factors of Early Mortality and Morbidity in Esophageal Atresia with Distal Tracheoesophageal Fistula: A Population-Based Cohort Study.

Objective: To identify the risk factors for early mortality and morbidity in a population with distal esophageal atresia (EA)-tracheoesophageal fistula.

Study Design: Cohort study from a national register. Main outcomes and measures included early mortality, hospital length of stay (LoS), need for nutritional support at 1 year of age as a proxy measure of morbidity, and complications during the first year of life.

Congenital Urethral Fistula: A Case Report and Literature Review.

Male congenital urethral fistula is an extremely rare condition. It is characterized by an abnormal opening of the ventral aspect of the penis. We report the case of a 1-month-old boy with congenital urethral fistula.

3D reconstruction of Wilms' tumor and kidneys in children: Variability, usefulness and constraints.

Introduction: Wilms' tumor (WT) is the most common type of malignant kidney tumor in children. Three-dimensional reconstructions can be performed pre-operatively to help surgeons in the planning phase.

Objectives: The main objective of this study was to determine the variability of WT segmentation and 3D reconstruction.

Fusion of multiple segmentations of medical images using OVASSION and Deep Learning methods: Application to CT-Scans for tumoral kidney.

Nephroblastoma is the most common kidney tumour in children. Its diagnosis is based on imagery. In the SAIAD project, we have designed a platform for optimizing the segmentation of deformed kidney and tumour with a small dataset, using Artificial Intelligence methods.

High Pressure Balloon Dilatation of Primary Obstructive Megaureter in Children: A Multicenter Study.

We described the initial experience of four referral centers in the treatment of primary obstructive megaureter (POM) in children, by high-pressure balloon dilatation (HPBD) of the ureterovesical junction with double JJ stenting. We managed a retrospective multicenter study to assess its effectiveness in long-term. We reviewed the medical records of all children who underwent HPBD for POM that require surgical treatment from May 2012 to December 2017 in four different institutions.

Dual intestinal anomalies in dizygotic twins.

We report on the case of two digestive malformations in dizygotic/dichorionic/diamniotic twins born at 31 weeks of gestation. The mother (gravida 1 para 0) was treated by hydroxychloroquine for systemic lupus erythematosus during pregnancy. Twin A presented an arch-like dilatation on antenatal ultrasounds, characteristic of segmental volvulus.

Current perspectives in robot-assisted surgery.

From classical surgery to robot-assisted surgery (RAS), there has been a long way allowed by the improvements achieved in minimally invasive surgery (MIS). The last three decades have witnessed a prodigious development of MIS, and especially in the field of laparoscopic pediatric surgery but there are several limitations in the use of conventional laparoscopic surgery and RAS was developed to relieve these drawbacks. This new technology enables today the performance of a wide variety of procedures in children with a minimally invasive approach.

How to Explore Fetal Sacral Agenesis Without Open Dysraphism: Key Prenatal Imaging and Clinical Implications.

The estimated prevalence of fetal caudal dysgenesis is 1 per 100,000 births. The functional prognosis of sacral agenesis is dominated by the large spectrum of associated caudal malformations. Except for cases associated with hydrocephalus secondary to open spinal dysraphism or chromosomal anomalies, association with mental deficiency is rare.

Objective: To evaluate the status of congenital diaphragmatic hernia (CDH) management in France and to assess predictors of adverse outcomes.

Study Design: We reviewed the first-year outcome of all cases of CDH reported to the French National Register in 2011.

Results: A total of 158 cases were included.

Management of nonparasitic splenic cysts in children: A French multicenter review of 100 cases.

Background: The management of nonparasitic splenic cysts (NPSC) remains controversial. Surgical resection is indicated for symptomatic or complicated forms, but no guidelines are available for asymptomatic NPSC. The aims of this study were to evaluate the management of NPSC in French hospitals and to analyze the results of management.

Prenatal intestinal volvulus: look for cystic fibrosis.

Intestinal volvulus is a life-threatening emergency requiring prompt surgical management. Prenatal intestinal volvulus is rare, and most are secondary to intestinal atresia, mesenteric defect or without any underlying cause. Cystic fibrosis (CF) is known to cause digestive tract disorders.

Long-term functional outcomes after penoscrotal hypospadias repair: A retrospective comparative study of proximal TIP, Onlay, and Duckett.

Introduction: A variety of techniques are available for proximal hypospadias repair. Onlay, proximal tubularized incised plate (TIP), and Duckett are among the popular choices because they can be performed as a one-step procedure. However, the decision to select a procedure often comes down to the surgeon's preference rather than that supported by evidence-based data.

Robot-assisted surgery: current status evaluation in abdominal and urological pediatric surgery.

Purpose: The last two decades have witnessed a dramatic development of minimally invasive surgery (MIS). Robotic-assisted surgery is currently the latest step in the evolution of MIS. MIS was initially developed for adult surgery, but its use has progressively been extended to pediatrics.
