Empirical data about contact frequencies of children is needed for estimating parameters in mathematical modelling studies that investigate the effect of targeting influenza intervention to children. A survey about the social contacts of school children was conducted in a primary school in Germany. The distribution of the daily numbers of contacts was(More)
BACKGROUND Child abuse is a recognized public health and social problem worldwide. Using data from the Multiple Indicator Cluster Surveys (MICS) we aimed to (i) compare different forms of child abuse across countries and regions, and (ii) examine factors associated with different forms of child abuse.

OBJECTIVE Amyloid deposition in multiple myeloma (MM) may lead to an arthropathy resembling rheumatoid arthritis (RA). Since a systematic description of its natural history is lacking, we have performed a systematic analysis of all published cases. METHODS Literature review featuring backward and forward database searches and direct inspection of(More)
BACKGROUND The need for the timely collection of diagnostic biosamples during symptomatic episodes represents a major obstacle to large-scale studies on acute respiratory infection (ARI) epidemiology. This may be circumvented by having the participants collect their own nasal swabs. We compared self- and staff-collected swabs in terms of swabbing quality(More)
OBJECTIVE The findings from truly randomized community-based studies on Staphylococcus aureus nasal colonization are scarce. Therefore we have examined point prevalence and risk factors of S. aureus nasal carriage in a non-hospitalized population of Braunschweig, northern Germany. METHODS A total of 2026 potential participants were randomly selected(More)
Parental attitudes towards childhood vaccinations are recognized to be important determinants of vaccination compliance. We examined this issue in Kyrgyzstan, a former Soviet Republic in Central Asia. Some parents expressed concerns about vaccination safety and/or were against mandatory vaccination. Although the fractions were lower than known from(More)
BACKGROUND Increased migration volume and different Hepatitis B prevalence between immigration and emigration countries have changed the Hepatitis B virus (HBV) epidemiology considerably in Northern and North-Western European migrants-receiving countries. Due to the difference in migration status monitoring, the HBV infection data on migrants are not easily(More)
We aimed to evaluate the fraction of exhaled nitric oxide (FENO50) and deaerated exhaled breath condensate pH (dEBCpH) as non-invasive markers of subclinical airway inflammation in pediatric patients with rheumatologic disorders. We determined FENO50 and dEBCpH in a prospective study spanning at least 12 months, comprising 85 pediatric patients with(More)
