BACKGROUND Influenza-associated myositis (IAM) is an infrequent and poorly known complication of influenza virus infection in children. The aim of this study was to describe five cases of IAM and to review the literature on IAM in children. PATIENTS AND METHODS We conducted a retrospective analysis of cases of IAM diagnosed at two university children's(More)
Children aged 9-11, 12-14 or 15-17 months, respectively were vaccinated with a measles, mumps and rubella (MMR) vaccine and serum antibody responses and reactogenicity were compared. The data of 118 children could be analysed (group 1=9-11 months, n=46; group 2=12-14 months, n=29, group 3, 15-17 months, n=43). The only significant difference observed was(More)
BACKGROUND Despite their potential for increased morbidity, 75% to 90% of asthmatic children do not receive influenza vaccination. Live attenuated influenza vaccine (LAIV), a cold-adapted, temperature-sensitive, trivalent influenza vaccine, is approved for prevention of influenza in healthy children 5 to 19 years of age. LAIV has been studied in only a(More)
UNLABELLED To further scientific progress of immunization safety, comparability of data from clinical trials and surveillance systems is essential. Comparability requires the availability of standardized case definitions for adverse events following immunization (AEFI) and guidelines for case determination, recording and data presentation.

OBJECTIVE Intussusception (IS) is one of the most common paediatric emergencies, and the best mode of conservative reduction and its exact incidence remains unclear. For different reasons, availability of reliable incidence data are useful and additionally may be fundamental to monitor potential effects of recently introduced rotavirus (RV) vaccines. (More)
There is a number of reports on varicella outbreaks in populations where a one dose varicella immunization program has been implemented. We performed a metaanalysis to provide a summary vaccine effectiveness (VE) estimate and to assess the possible impact of waning immunity by means of a subgroup analysis by time since immunization. We found a VE of 72.5%(More)
OBJECTIVES To evaluate the attitudes of pediatric healthcare workers (HCWs) toward influenza vaccination and to increase their rate of immunization. METHODS A survey was conducted among pediatric HCWs using an anonymous questionnaire. Survey results were used to design an intervention to increase the immunization rate of staff. Immunization rates before(More)
Whereas immunization coverage has been repeatedly assessed in the Swiss population, little is known about the timely administration of universally recommended immunizations in Switzerland and elsewhere. The goal of this study was to determine compliance with official standard immunization recommendations in pre-school and school-aged children in Basel,(More)
