[Eosinophilic esophagitis in children: Evaluation of practices through a multicenter study]. / L'œsophagite à éosinophiles chez l'enfant : évaluation des pratiques.

Eosinophilic esophagitis (EE) is a recent pathology defined by abnormal immune response of the esophageal mucosa to exogenous allergens, leading to chronic mucosa infiltration by 15 eosinophils per High-Power-Field (Eos/HPF). The present retrospective study was designed to assess the hospital care for children suffering from EE in several hospitals in western France in order to highlight discrepancies and improve future care. Twenty-eight children ranging from 1.5 months to 17 years old were included in the study. Episodes of food blockage were the most frequently reported symptoms (46 %). A ratio of 29 % of EE patients reported macroscopically normal endoscopy; diagnosis was then established upon histological anomalies found in biopsies. The mean eosinophil count was 72.4 Eos/HPF. Centralized immunohistochemical staining revealed the presence of IgG4-responding plasma cells in 76.5 % of patients, as well as IgG4 intraepithelial degranulation in 14 % of them. The evaluation of the treatment plan showed important inter-center discrepancies with only 43 % of patients receiving endoscopic reevaluation. This study objectively highlights heterogeneities in diagnosis and care provided to children suffering from EE. Therefore, improving the consistency of practices seems to be crucial to optimize the patients' outcome. The role of IgG4 as a new diagnosis marker remains to be clarified.

[Peroperative anaphylactic shock in children: management and evaluation]. / Choc anaphylactique peropératoire chez l'enfant : prise en charge et bilan.

Anaphylactic shock is the most severe manifestation of hypersensitivity, whether of allergic origin or not. In the operating theatre, anaphylactic shock is rare in paediatric patients and latex allergy is still the major cause of allergy. Whatever the cause and mechanism of the reaction, its treatment should be started as early as possible: a high level of suspicion is thus necessary to establish a diagnosis as early as possible. Symptomatic treatment is well codified. The results of blood sampling at the time of the reaction and of allergic tests performed a few weeks later will enable a definitive diagnosis to be made and appropriate recommendations (medical alert card) to be given to the patients and its parents.

[Bronchial erosion of mediastinal lymphadenopathy associates with Hodgkin's disease]. / Fistulisation d'adénopathies médiastinales dans les bronches en rapport avec une maladie de Hodgkin.

INTRODUCTION: Erosion of mediastinal adenopathy into the bronchial tree is classically associated with tuberculosis. We describe two cases of of such bronchial erosion with Hodgkin's disease. CASE REPORT: The first case was of a seventy-year old man with a history of pulmonary silicosis. A sub-carenal mass was identified during investigation of chronic cough. The bronchoscopy revealed an inflammatory stenosis due to Hodgkin's disease. The second case was of a thirteen-year old child whose Hodgkin's disease was thought to be in remission following treatment. The erosion of mediastinal adenopathy into the main left bronchus produced complete left pulmonary atalectasis, which required endobronchial stenting. CONCLUSIONS: In both cases, rigid bronchoscopy provided a histological diagnosis with diagnosis of Hodgkin's disease in the first case, and identification of recurrence in the other one. These cases are unusual. Such complications are usually complications of radiotherapy. Classically, erosion of mediastinal adenopathy into the bronchial tree is tuberculous in origin but they can be neoplasic.
