ABSTRACT

Acute liver failure (ALF) in childhood is a life-threatening emergency. ALF is often caused by drug toxicity, autoimmune hepatitis, inherited metabolic diseases, and infections. However, despite thorough investigations, a cause cannot be determined in approximately 50% of cases. Here, we report three cases with recurrent ALF caused by NBAS and SCYL1 pathogenic variants. These patients did not present with any other phenotypic sign usually associated with NBAS and SCYL1 pathogenic variants. Two of them underwent liver transplantation and are healthy without recurrence of ALF. We propose NBAS and SCYL1 genetic analysis in children with unexplained fever-triggered recurrent ALF even without a typical phenotype.

ABSTRACT

OBJECTIVE: Congenital diaphragmatic hernia (CDH) is a severe anomaly. The observed-to-expected lung-area-to-head-circumference ratio (o/e-LHR) has been shown to provide a useful prediction of subsequent survival of fetuses with CDH in referral centers with expertise and a large caseload. However, the accuracy of o/e-LHR measurements in general fetal medicine units with less expertise is not well known. The aim of this study was to evaluate the capacity of o/e-LHR to provide a useful prediction of mortality of fetuses with CDH when the measurement is performed in fetal medicine units with different levels of expertise. METHODS: Between January 2008 and November 2013, 305 live births with expectantly managed left-sided isolated CDH were recorded in the database of the French National Center for Rare Diseases (31 centers) and followed up after birth. Centers were grouped into two categories according to their mean annual CDH caseload over the study period: large centers with an average of ≥ 14 cases and smaller centers with < 14 cases per year. The relationship between o/e-LHR and 28-day and 6-month mortality was modeled using fractional polynomials and the predictive value of o/e-LHR was quantified using the area under the receiver-operating characteristics curve. Comparisons between the two center categories were carried out. Analyses were adjusted for potential confounders such as thoracic herniation of the liver and gestational age at birth and at diagnosis. RESULTS: During the study period, two large centers managed a total of 82 CDH cases and 29 smaller centers a total of 223 CDH cases. Overall, there was a significant inverse relationship between 28-day mortality rate and o/e-LHR, which decreased from 54% when o/e-LHR was 20% to 6% when o/e-LHR was 75% (P < 0.01). When the category of center was considered, adjusted associations between o/e-LHR and 28-day mortality were significantly different (P = 0.032) between large and smaller centers. The ability to predict survival at 28 days postpartum based on o/e-LHR was better in large centers; for a specificity of 0.30, the sensitivity was 0.71 in large centers and 0.55 in smaller ones. The results were similar for 6-month mortality. CONCLUSIONS: Our results show that o/e-LHR measured on two-dimensional ultrasound is a good indicator of neonatal prognosis in cases of CDH that may be used even in fetal medicine centers with a small caseload. However, our results also suggest that LHR measurement may be difficult to perform correctly. Therefore, appropriate training should be offered to professionals. Copyright © 2017 ISUOG.

ABSTRACT

The French Rare Disease Reference Center for congenital diaphragmatic hernia (CDH) was created in 2008, to implement a national protocol for foetuses and children with this serious condition. Neonatal mortality from CDH is 30-40%, mainly due to pulmonary hypoplasia and persistent pulmonary hypertension, and half of those who live have high respiratory, nutritional and digestive morbidity. CDH management requires long-term and specialised multidisciplinary care. It has been well established that a standardised management protocol improves the prognosis of children with CDH. CONCLUSION: Organising health care and implementing a nationwide French protocol were key factors for reducing mortality and morbidity from CDH.

ABSTRACT

Abnormalities of the male genitalia have increased in the last 2 decades in numerous developed countries and remain a frequent reason of consultation in pediatric surgery. The diagnostic spectrum is wide, and surgeons should pay particular attention to these abnormalities because of their potential psychological effect. Anatomically, these abnormalities can affect one of three parts of the penis. First, the foreskin may not be fully retracted. This is normal at birth and can be caused by prepuce adherents that can continue until adolescence. Today, true phimosis is treated with topical corticoids from the age of 3 years. If medical treatment fails, a surgical procedure is required. Second, the urethra can be affected by hypospadia, which is the most frequent abnormality of the urethra. It is associated with ectopic urethral meatus, hypoplastic foreskin, and penis curvature. Its pathogenic background is not clearly understood. Surgery options differ according to the type of hypospadia and according to the surgeon's experience. It is sometimes hard to deal with, especially in a perineal form, where genetic and hormonal studies are recommended. These interventions can lead to complications ranging from stenosis to fistula. Therefore, parents have to be informed of the benefits and risks of the surgical procedures. Epispadias is rare but more serious because of the increasing risk of urinary incontinence. Finally, abnormalities of the corpora cavernosa - often associated with hypospadias - can include penis curvature and micropenis, for which an endocrinological analysis is essential.

ABSTRACT

Eosinophilic cystitis (EC) is a rare disease that frequently suggests a bladder tumour at presentation. It affects both children and adults and its pathophysiology remains unclear. EC usually shows a benign course, but serious complications can occur and relapsing forms have been described. It has rarely been reported in children and therefore, might be poorly known by physicians and underdiagnosed. We report a case that differs from other observations by its unusually rapid resolution, and review the literature on EC's diagnosis, treatment, and course in children.

ABSTRACT

PURPOSE: The aim of this study was to evaluate the prognostic significance of intrarenal reflux (IRR) regarding urinary tract infection (UTI), renal scarring and spontaneous resolution after 3 years of follow up. PATIENTS AND METHODS: 33 patients (42 refluxing units) with IRR were compared to 27 children (44 refluxing units) with high-grade vesicoureteral reflux (VUR) without IRR (controls) matched for gender, age and VUR grade. All patients received antibiotic prophylaxis during observation and antireflux surgery was performed in children with recurrent UTI. DMSA scan was performed at study entry, and 18 and 36 months. RESULTS: DMSA scores at entry showed a higher proportion of moderate and severe damage in the IRR group (25/42) compared to the control group (16/44) (Chi squared, P < 0.03). During follow up the incidence of UTI was similar in the two groups, as well as the stability of DMSA scintigraphy and the rate of spontaneous disappearance of the reflux. A similar proportion of patients underwent surgery (18/33 patients with IRR and 13/27 control patients; Chi squared, not significant). CONCLUSIONS: Under medical management, the prognosis for IRR is not different from high-grade VUR without IRR. The presence of IRR does not justify more aggressive management than a high-grade VUR without IRR.
