  abstract  = {Background and objectives: Urticaria is a frequent skin condition, but reliable prevalence estimates from population studies particularly of the chronic form are scarce. The objective of this study was to systematically evaluate and summarize the prevalence of chronic urticaria by evaluating population-based studies worldwide. Methods: We performed a systematic search in PUBMED and EMBASE for population-based studies of cross-sectional or cohort design and studies based on health insurance/system databases. Risk of bias was assessed using a specific tool for prevalence studies. For meta-analysis, we used a random effects model. Results: Eighteen studies were included in the systematic evaluation and 11 in the meta-analysis including data from over 86 000 000 participants. Risk of bias was mainly moderate, whereas the statistical heterogeneity (I\(^{2}\)) between the studies was high. Asian studies combined showed a higher point prevalence of chronic urticaria (1.4\%, 95\%-CI 0.5-2.9) than those from Europe (0.5\%, 0.2-1.0) and Northern American (0.1\%, 0.1-0.1). Women were slightly more affected than men, whereas in children < 15 years we did not find a sex-specific difference in the prevalence. The four studies that examined time trends indicated an increasing prevalence of chronic urticaria over time. Conclusions: On a global level, the prevalence of chronic urticaria showed considerable regional differences. There is a need to obtain more sex-specific population-based and standardized international data particularly for children and adolescents, different chronic urticaria subtypes and potential risk and protective factors.},

  abstract  = {Background The allergy preventive effects of gut immune modulation by bacterial compounds are still not fully understood. Objective We sought to evaluate the effect of bacterial lysate applied orally from the second until seventh months of life on the prevalence of allergic diseases at school age. Methods In a randomized, placebo-controlled trial, 606 newborns with at least one allergic parent received orally a bacterial lysate consisting of heat-killed Gram-negative Escherichia coli Symbio and Gram-positive Enterococcus faecalis Symbio or placebo from week 5 until the end of month 7. A total of 402 children were followed until school age (6-11 years) for the assessment of current atopic dermatitis (AD), allergic rhinitis (AR), asthma and sensitization against aeroallergens. Results AD was diagnosed in 11.0\% (22/200) of children in the active and in 10.4\% (21/202) of children in the placebo group. AR was diagnosed in 35\% (70/200) of children in the active and in 38.1\% (77/202) children in the placebo group. Asthma was diagnosed in 9\% (18/199) of children in the active and in 6.6\% (13/197) of children in the placebo group. Sensitization occurred in 46.5\% (66/142) of participants in the active and 51.7\% (76/147) in the placebo group. Conclusion An oral bacterial lysate of heat-killed Gram-negative Escherichia coli and Gram-positive Enterococcus faecalis applied during the first 7 months of life did not influence the development of AD, asthma and AR at school age.},

  abstract  = {Hintergrund. Die Entwicklung und das Wohl von Kindern aus Familien mit schweren psychosozialen Belastungen k{\"o}nnen schon in der Schwangerschaft und im S{\"a}uglingsalter gef{\"a}hrdet sein. In der Geburtsmedizin in Deutschland fehlen einfache, valide Fr{\"u}hwarnsysteme, um Risikofamilien rechtzeitig zu identifizieren. Zielsetzung. Unser Ziel war es, die diagnostische Genauigkeit eines perinatal eingesetzten, einfachen Screeningbogens zur Identifizierung psychosozial belasteter Familien zu evaluieren. Methoden. F{\"u}r alle Geburten der Berliner Charit{\´e} im Zeitraum 1.1.-31.8.2013 f{\"u}llte medizinisches Personal im Rahmen des Projekts Babylotse-Plus einen 5-min{\"u}tigen Screeningbogen mit 27 Items aus. Ein daraus resultierender Summenscore ≥3 wurde als „auff{\"a}llig" definiert. Anschließend erfolgte zur genauen Erfassung der famili{\"a}ren Ressourcen undm{\"o}glicher psychosozialer Belastungen ein einst{\"u}ndiges, standardisiertes Elterninterview, welches als Referenzstandard f{\"u}r die Evaluation des Screeningbogens verwendet wurde. Ergebnisse. In die vorliegende Analyse konnten 279 Familien eingeschlossen werden. Beim Vergleich der 215 Familien mit „auff{\"a}lligem" Score mit einer Zufallsauswahl von 64 Familien mit „unauff{\"a}lligem" Score <3, zeigte sich f{\"u}r den Screeningbogen eine hervorragende Sensitivit{\"a}t (98,9\%; 95\%- Konfidenzintervall 93,4-99,9\%), jedoch nur eine geringe Spezifit{\"a}t (33,0\%; 95\%- Konfidenzintervall 30,5-33,5\%). Die daraus resultierende positive Likelihood Ratio fiel mit 1,5 schwach, die negative Likelihood Ratio dagegen mit 0,03 sehr gut aus. Schlussfolgerungen. Mithilfe des Screeningbogens konnten psychosoziale Risikofamilien sehr gut identifiziert werden, jedoch wurden auch viele Familien ohne oder mit nur einem geringen Risiko f{\"a}lschlicherweise als unterst{\"u}tzungsbed{\"u}rftig eingestuft. Weitere Studien sollten in anderen Settings und zur Verbesserung der Spezifit{\"a}t bei m{\"o}glichst gleichbleibender Sensitivit{\"a}t des Screeningbogens durchgef{\"u}hrt werden.},
