STUDY POPULATION. Data were analyzed from the anaphy-laxis registry of German-speaking countries, which included 197 reported anaphylactic reactions from children and adolescents between 2006 and 2009. This database is based on an online questionnaire for providers of allergy specialty care in Germany, Austria, and Switzerland. METHODS. The questionnaire included demographic data, clinical symptoms, the cause of reaction, accompanying or possible aggravating factors, history of previous reaction , and treatment. To focus on reactions that involved life-threatening symptoms, only children who experienced reactions with at least 1 pulmonary or cardio-vascular symptom were included in the analysis. RESULTS. The most frequently affected organ systems involved in anaphylaxis cases of children and adolescents were the skin (89%) and respiratory tract (87%). Car-diovascular (47%) and gastrointestinal manifestations (43%) were noted less frequently. The most common triggering allergens were foods (58% of cases), followed by insect venoms (24%) and drugs (8%). Peanut was the most frequent food allergen provoking anaphylaxis, followed by tree nuts, cow's milk, and egg. Accompanying or aggravating factors, such as exercise, drug use, coexisting infection, psychological stress, and menses, were noted in 18% of all cases. Only 26% had a history of a previous reaction. Treatment data demonstrated that antihistamines were given 87% of the time and corticosteroids were given 85% of the time, but epi-nephrine was given only 22% of the time. CONCLUSIONS. Use of registry data can provide insight into the features of children presenting with anaphylaxis. Food allergens were the most common triggers for anaphylaxis and possible aggravating factors were noted in nearly 1 in 5 cases, with exercise being the most common. The low frequency of epinephrine administration suggests ongoing need for education for both families and physicians. REVIEWER COMMENTS. This study aimed to characterize children with life-threatening anaphylactic reactions by selecting those with cardiovascular and/or pulmonary involvement. Consistent with other studies, food aller-gens (most commonly peanut) were the most frequent trigger for reaction. The rate of accompanying or aggravating factors suggests that these should be considered in evaluation of all children with anaphylaxis. The low rate of epinephrine use is concerning, especially given that this study focused on more severe reactions, although this is consistent with most other studies of anaphylaxis from around the world. et al. Clin Exp Allergy. 2011;42(2):284-292 PURPOSE OF THE STUDY. To evaluate the rate at which adrenaline autoinjectors are used during anaphylactic reactions by patients who have had them prescribed, and to assess the number of devices used for each reaction. STUDY POPULATION. Participants (N 5 969) were children and teenagers aged 18 years or less who had been prescribed an adrenaline autoinjector for at least 1 year, recruited from 14 pediatric allergy clinics throughout the Unite...

Peutz-Jeghers syndrome (PJS) is a well-described inherited syndrome, characterized by the development of gastrointestinal polyps, and characteristic mucocutaneous freckling. Development of small bowel intestinal polyps may lead to intussusception in children may require emergency laparotomy with potential loss of bowel. Gastrointestinal polyps may lead to bleeding and anemia. This European Society for Paediatric Gastroenterology Hepatology and Nutrition position paper provides a guide for diagnosis, assessment, and management of PJS in children and adolescents and guidance on avoiding complications from PJS or from the endoscopic procedures performed on these patients. This is the first position paper regarding PJS published by European Society for Paediatric Gastroenterology Hepatology and Nutrition. Literature from PubMed, Medline, and Embase was reviewed and in the absence of evidence, recommendations reflect the opinion of pediatric and adult experts involved in the care of polyposis syndromes. Because many of the studies that form the basis for the recommendations were descriptive and/or retrospective in nature, some of the recommendations are based on expert opinion. This position paper will be helpful in the appropriate management and timing of procedures in children and adolescents with PJS.

The European Society for Paediatric Gastroenterology, Hepatology and Nutrition (ESPGHAN) Polyposis Working Group developed recommendations to assist clinicians and health care providers with appropriate management of patients with juvenile polyposis. This is the first juvenile polyposis Position Paper published by ESPGHAN with invited experts. Many of the published studies were descriptive and/or retrospective in nature, consequently after incorporating a modified version of the GRADE system many of the recommendations are based on expert opinion. This ESPGHAN Position Paper provides a guide for diagnosis, assessment, and management of juvenile polyposis syndrome in children and adolescents, and will be helpful in the appropriate management and timing of procedures in children and adolescents. The formation of international collaboration and consortia is proposed to monitor patients prospectively to advance our understanding of juvenile polyposis conditions.
