Esophageal perforation in eosinophilic esophagitis: five cases in children

Background and study aims  Eosinophilic esophagitis (EoE) is a chronic immune disease with increasing incidence. It is clinically defined by symptoms of esophageal dysfunction and histologically by eosinophilic polynuclear cell infiltration of the esophageal mucosa. Symptoms are not specific and include gastroesophageal reflux disease (GERD), dysphagia, vomiting or dietary blockages. Chronic inflammation of the mucosa may lead to narrowing of the esophageal lumen responsible for impactions. Extraction procedures can be complicated by dissection and perforation. Rare spontaneous ruptures of the esophagus known as Boerhaave syndrome are also possible. We report five cases of esophageal perforation in children with EoE, three with spontaneous rupture and two after an endoscopic procedure. The evolution was favorable under medical treatment

Prenatal imaging features suggestive of liver gestational allo immune disease

International audienceWe report prenatal imaging features of four cases of neonatal hemochromatosis due to an alloimmune disease. All cases exhibited intra uterine growth restriction (IUGR) without arguments for a vascular etiology, associated with oligohydramnios. Placental hydrops was present in 75% of cases. Splenomegaly was identified in one case. Other causes of NH have been ruled out during diagnostic workup including karyotype, detection of IGFBP-1 to evaluate a premature rupture of membranes, maternal serologic tests. MRI was performed in two cases and showed an atrophic liver associated with a low signal intensity on T2-sequence in one case. Prenatal NH was suspected in this later case and the fetus was successfully treated with two IVIG (intravenous immunoglobulins) perfusions performed during pregnancy followed by exchange transfusion and IVIG after birth. The child is doing well with normal liver function tests after 17 months of follow up. Our aim was to highlight the importance of suggesting NH-GALD when facing IUGR with oligohydramnios, ascites, placental hydrops, splenomegaly on prenatal ultrasound with negative work up for placental vascular pathologies and infectious fetopathies. MRI might be of a good help, showing an atrophic liver but enhancing iron overload in hepatic and extrahepatic tissue is helpful but not constant

Dramatic increase of central venous catheter-related infections associated with a high turnover of the nursing team

International audienceBACKGROUND & AIMS: This retrospective study evaluated the impact of new organization during the moving to a new university pediatric hospital on the incidence of central catheter-related blood stream infections (CRBSIs) among children on long-term parenteral nutrition. METHODS: The study ran from April 2007 to March 2014, starting a year prior to reorganisation of the department of pediatric Hepato-Gastroenterology and Nutrition associated to moving the children to a new hospital in April 2008, and continuing for 6 years following the move. During this time, data from all children hospitalized in this department who received parenteral nutrition (PN) for more than 15 days were analysed. RESULTS: During this 7-years study, 183 children aged 4.6 +/- 0.5 years received prolonged PN. Intestinal diseases were the main aetiologies (89%), primarily short bowel syndrome (18.4%), Hirschsprung disease and CIPO (13.5%) and inflammatory bowel disease (13.8%). The mean durations of hospitalization and of PN during hospitalization were, respectively, 70 +/- 2.1 and 55.7 +/- 3.6 days. During the study period, 151 CRBSIs occurred in 77 children (42% of all patients), i.e. 14.8 septic episodes/1000 PN days and 12.0 septic episodes/1000 CVC days. No patient died of a central venous catheter-related infection. However, following the move from the older hospital to the newer one, the rate of CRBSIs significantly doubled, from 3.9/1000 to 8.8/1000 CVC days (p = 0.02). During the following 4 years, the incidence of CRBSIs tended to increase between the 2nd and the 5th year after the move: 11.3 (p = NS); 21.4 (p = 0.01); 17.3 (p = NS), 20.3/1000 (p = NS) CVC days. We also observed that after evaluations by the Department of Infection Control, nurse training and stabilization of the nursing team, the incidence decreased significantly from 20.3 to 11.1/1000 CVC days during the 6th year after the move (p = 0.01). CONCLUSION: Our results reveal the deleterious impact of the reorganization during the hospital moving on the CRBSI incidence rate, and the possible implication of inexperienced team of nurses

Increase of recurrent central line-associated bloodstream infections in children with home parenteral nutrition in a rehabilitation care facility compared to home

International audienceBACKGROUND AND AIMS: Central line-associated bloodstream infections (CLABSIs) are the main complication in children with home parenteral nutrition (HPN) and some patients develop recurrent CLABSIs (REC-CLABSIs), defined as two or more infections within six months. Our aims were to assess the incidence and to characterize the risk factors of REC-CLABSIs in children with HPN. METHODS: We characterized 79 HPN children from 2014 to 2019 and calculated the incidence of CLABSIs. To minimize the risk of bias related to the exposure time of the septic risk, we paired the patients according to their central venous catheter (CVC) dwell time. After analyzing the whole cohort, a univariate and multivariate unconditional logistic regression was performed on the paired cohort. RESULTS: We included 75 (94.9%) children with a mean age of 7.11 years. The rate of septicemia was 1.55/1000 CVC days, mainly with Staphyloccocus sp. The patients with recurrent CLABSIs (REC group) represented 25% of the cohort, with an incidence of 2.99/1000 CVC days. In the whole cohort, a higher risk of recurrent infections was significantly associated with a longer CVC dwell time (OR = 1.04, IC 95% [1.01-1.06], p = 0.004), and with care located in rehabilitation care facilities (RCF) compared to home (OR = 6, IC 95% [1.5-26.6], p = 0.012). When children were paired according to their CVC dwell time, only in univariate analysis did the care in RCF remain significant (OR = 6.27, IC 95% [1.21-32.5], p = 0.03). CONCLUSIONS: Recurrent CLABSIs incidence was 2.99/1000 CVC days. Our study suggests that preventive measures should be implemented especially in RCFs to reduce the proportion of children with recurrent infections. A multicenter study is needed to confirm our results in a larger cohort with several RCFs

Relevance of C5b9 immunostaining in the diagnosis of neonatal hemochromatosis

BACKGROUND: Neonatal hemochromatosis caused by a gestational alloimmune mechanism or gestational alloimmune liver disease (GALD) is a rare perinatal disorder characterized by intra- and extrahepatic iron overload. It is believed to result from complement-mediated liver injury, in which the classical complement pathway is activated by maternal antibody/fetal antigen complexes, leading to hepatocyte lysis by the membrane attack complex C5b9. According to some authors, C5b9 expression in more than 75% of liver parenchyma is specific for GALD. // METHODS: We conducted a retrospective multicentric immunohistochemical study with anti-C5b9 in GALD cases (n = 25) and non-GALD cases with iron overload (n = 36) and without iron overload (n = 18). // RESULTS: C5b9 was expressed in 100% of GALD cases but involved more than 75% of the liver parenchyma in only 26% of the cases. C5b9 was detected in 26.75% of the non-GALD cases with more than 75% of positive parenchyma in maternal erythrocytic alloimmunization, herpes and enterovirus hepatitis, bile acid synthetic defect, DGUOK mutation, Gaucher disease, cystic fibrosis, and giant-cell hepatitis with autoimmune hemolytic anemia. // CONCLUSION: Diagnosis and therapeutic management of GALD cannot only be based on C5b9 expression in liver samples as it is not specific of this disease
