[Proton pump inhibitors in pediatrics: Review of the prescriptions' relevance for hospitalised children in a university hospital]. / Les inhibiteurs de la pompe à protons en pédiatrie : audit des prescriptions chez les enfants hospitalisés dans un centre hospitalier universitaire.

INTRODUCTION: Proton Pump Inhibitors (PPIs) are a pharmacological class designed to reduce the acidity of gastric secretions. They are prescribed for 11 % of the children in our institution. AIMS: To assess the relevance of PPI prescriptions in pediatrics. MATERIAL AND METHOD: A clinical audit according to the methodology proposed by the High Authority of Health was carried out between August 27 and August 31, 2018 in the pediatric departments of our institution. The main judgement criteria were the indication of the PPI. The main guidelines are the recommendations of the European society of pediatric gastroenterology, hepatology and nutrition. RESULTS: Thirty patients were included. The average age was 8.6 years. The indication was compliant in 19 patients. The non-compliant indications were: two ulcer risk preventions related to the prescription of non-steroidal anti-inflammatory drugs (NSAIDs), one endoscopic biopsy, four ulcer risk preventions related to corticosteroid therapy, one hematopoietic stem cell transplantation and three mucositis. DISCUSSION: The sample of patients included in the study was representative of the pediatric population with PPIs in our institution. The non-conformities identified could be justified in some cases. Only one study reported a compliance rate for PPI indications in pediatrics in the literature. This rate, in the order of 34 %, was much lower than that found in our institution (P<0.01). CONCLUSION: The respect of the latest recommendations for the prescription of PPIs is quite good. A usage sheet will be diffused to improve the practices.

Are vaccinated measles cases protected against severe disease?

OBJECTIVES: We aimed to estimate vaccine effectiveness against severe measles based on the number of vaccine doses administered and the time since last vaccination. PATIENTS AND METHODS: We included measles cases aged at least 2 years and born since 1980 who were notified in France between 2006 and mid-2019. We considered two severity levels (moderate, severe) and calculated adjusted relative risks (aRR) using multinomial logistic regression. RESULTS: We included 10,399 cases. The risk of severe measles in two-dose vaccine recipients was 71% (aRR = 0.29 [95%CI 0.12-0.72]) and 83% (aRR = 0.17 [95%CI 0.04-0.70]) lower than in unvaccinated cases, if the time since last dose was less or more than 15 years, respectively. The risk of moderate disease followed a similar pattern. CONCLUSIONS: Two-dose measles vaccination provided long-term protection against severe cases, even after vaccine failures. These findings underscore the need for compliance to the recommended measles vaccination schedule to prevent severe cases.

Management of eosinophilic esophagitis in children according to atopic status: A retrospective cohort in northeast of France.

INTRODUCTION: Most children with eosinophilic esophagitis (EoE) are atopic, but the impact of atopy on the remission and development of EoE is still unclear. The aim of our study was to determine the impact of atopy on remission of EoE and to describe allergy tests and the choice of treatment for a cohort of EoE children in France. METHODS: All children diagnosed with EoE between January 2013 and June 2018 in the five pediatric centers in the northeast of France were included. Children were divided into two groups according to personal atopic disorders. Histological remission was defined on the basis of an eosinophilic count below 15 eosinophils per high-power field. RESULTS: Among the 49 children included, 38 (78%) were atopic. Allergy tests were performed for 45 children (92%). Rates of sensitization were similar in both groups: 64% had food sensitization and 64% had aeroallergen sensitization. The most commonly attempted first-line therapy was with proton pump inhibitors (63%), followed by swallowed topical steroids (STS) (18%). First-line therapy was not associated with atopic status (P=0.88). Atopic children had a nonsignificant tendency for a higher remission rate after STS (55% vs. 0%, P=0.24) and a higher global remission rate (54% vs. 33%, P=0.18) compared with non-atopic children. CONCLUSION: Allergy testing is relevant in the majority of children with EoE whether or not they have atopic disorders. Atopy seems to be associated with better response to STS. Further studies are needed to determine whether atopic status determines histological response.

Healthcare workers' knowledge and perceptions of the risks associated with emerging extensively drug-resistant bacteria.

OBJECTIVE: Guidelines have been issued in 2010 to prevent the spread of emerging extensively resistant bacteria (eXDR), but their implementation is difficult. We aimed to evaluate healthcare workers' (HCW) knowledge and their risk perception to identify barriers to the implementation of guidelines. METHODS: Semi-structured interviews were conducted at a University Hospital, where case patients are regularly admitted. The interviews focused on HCW's knowledge, risk perception, and challenges met. The evaluation of HCW's knowledge and contagiousness and perception of severity of eXDR carriage were analyzed statistically. Risk perception and opinion about guidelines were analyzed by qualitative description. RESULTS: One hundred and twenty-one HCWs were interviewed. The category of HCW, having searched for information on resistant bacteria, and having taken care of case patients were associated with better knowledge. The HCW category, age, type of unit, seniority, and having taken care of case patients were associated with risk perceptions. Qualitative analysis identified 61 themes. HCWs were extremely concerned by the spread of bacteria within the hospital. The main challenges identified were organizational and communication issues. CONCLUSION: HCWs reported a lack of knowledge and a lack of resources to implement guidelines. Strategies to improve guidelines implementation must be based on a better availability of resources, better communication, and new educational methods.
