[Magnet ingestions in children: a French multicenter study]. / Ingestion de corps étrangers aimantés chez l'enfant: enquête multicentrique française.

Digestive complications related to the ingestion of magnetic foreign bodies in children are increasing, especially in Asia and North America. In France, several case reports have been reported since 2008. We conducted a retrospective multicentric study to evaluate the frequency of ingestion of magnet foreign bodies and to describe the complicated cases that have occurred in France over the last 5 years. We report 40 cases of which 60% were multiple magnet ingestions. Eighty-eight percent of the children of the group who had swallowed multiple magnets needed interventional management by endoscopy (33%) or surgery (58%). Only two children (12.5%) of the group who swallowed one magnet required removal. This problem is not uncommon in France (2% of the 1132 foreign bodies investigated in the Toulouse center over 5 years), which justifies clear information for healthcare professionals and caregivers in order to avoid potential intestinal complications. We suggest interventional management or very close monitoring in the cases of multiple magnet ingestion. Meanwhile, in the majority of confirmed cases of simple magnet ingestions, we propose home monitoring.

[Assessment of medical students using a script concordance test at the end of their internship in pediatric gastroenterology]. / Évaluation des étudiants en médecine lors de leur stage en gastro-entérologie pédiatrique par un test de concordance de script.

The Script Concordance Test (SCT) is a tool used to evaluate clinical reasoning in complex medical situations. Our aim was to create the first SCT in pediatric gastroenterology in order to objectively assess medical students. We elaborated a SCT including 31 items divided into ten clinical cases. Topics were chosen within the list comprising the national academic exam. In order to assess medical students, a reference panel was made up of ten residents to establish the scoring process. Answers were noted on a Likert scale, ranging from -2 to +2. Scores were calculated based on the modal response. Depending on the variation of the experts' answers to each item, we classified the questions as correct, incorrect, or uncertain. The SCT was also taken by five GI pediatricians. The results were given as mean/20 ± SEM. The Student t-test was used for the statistical analysis. The scores were 15.35 ± 0.38 and 12.44 ± 0.58 (P=0.0006), respectively, for the reference panel and the students. Scores were unchanged by removing incorrect and uncertain questions. However, the score of the GI pediatricians was 13.37 ± 0.69, significantly lower than the reference panel (P=0.01). The reliability of this SCT is subject to debate. This was the first time the students had taken a SCT, but they considered that this tool was appropriate and in concordance with the objectives. Although the SCT is a useful method, its elaboration can be difficult. It seems important to create a group of teachers to validate the process and eliminate the wide variability.

[Candida albicans endocarditis after pulmonary artery banding]. / Endocardite àCandida albicans sur cerclage de l'artère pulmonaire.

Endocarditis is uncommon in infants and is exceptionally related to Candida albicans on pulmonary banding. We report on a case in a 7-month-old infant who had pulmonary artery banding for a ventricular septal defect and who presented with candidal endocarditis. Banding was chosen because of the patient's poor trophic and unstable status, which could be risky for surgery involving extracorporeal circulation. A few weeks after the banding, the patient developed systemic Candida infection, which was treated successfully. At 7 months, cardiac failure appeared without fever or inflammatory signs. Cardiac echography showed that the banding was not protective as well as a hyperechogenic image on the pulmonary bifurcation. The angioscan showed a hypodense thrombus. Emergency surgery was performed consisting of pulmonary artery exploration, thrombectomy, and ventricular septal defect closure. The exploration showed a pulmonary artery perforation caused by the infected pseudoaneurysm and the migration of the banding into the pulmonary artery. The anatomopathologic analysis of the vegetation identified multisensitive Candida albicans. After surgery and prolonged antifungal treatment, progression was satisfactory.
