Identification and characterization of the bacterial etiology of clinically problematic acute otitis media after tympanocentesis or spontaneous otorrhea in German children

Abstract Background Acute Otitis Media (AOM) is an important and common disease of childhood. Bacteria isolated from cases of clinically problematic AOM in German children were identified and characterized. Methods In a prospective non-interventional study in German children between 3 months and less than 60 months of age with Ear, Nose and Throat Specialist –confirmed AOM, middle ear fluid was obtained by tympanocentesis (when clinically indicated) or by careful sampling of otorrhea through/at an existing perforation. Results In 100 children with severe AOM, Haemophilus influenzae was identified in 21% (18/21, 85.7% were non-typeable [NTHi]), Streptococcus pneumoniae in 10%, S. pyogenes in 13% and Moraxella catarrhalis in 1%. H. influenzae was the most frequently identified pathogen in children from 12 months of age. H. influenzae and S. pneumoniae were equally prevalent in children aged 3–11 months, but S. pyogenes was most frequently isolated in this age group. NTHi AOM disease appeared prevalent in all ages. Conclusions NTHi, S. pneumoniae and S. pyogenes are implicated as important causes of complicated AOM in children in Germany. NTHi disease appears prevalent in all ages. The impact of vaccination to prevent NTHi and S. pneumoniae AOM may be substantial in this population and is worth investigating.</p

The Alberta Congenital Anomalies Surveillance System: a 40-year review with prevalence and trends for selected congenital anomalies, 1997–2019

IntroductionCurrent published long-term provincial or territorial congenital anomaly data are lacking for Canada. We report on prevalence (per 1000 total births) and trends in 1997–2019, in Alberta, Canada, for selected congenital anomalies. Associated risk factors are also discussed. MethodsWe used data from the Alberta Congenital Anomalies Surveillance System (ACASS) to calculate the prevalence and perform chi-square linear trend analyses. ResultsFrom 1997 to 2019, the overall prevalence of neural tube defects was stable, at 0.74 per 1000 total births. The same was true for spina bifida (0.38), orofacial clefts (1.99), more severe CHDs (transposition of the great arteries, 0.38; tetralogy of Fallot, 0.33; and hypoplastic left heart syndrome, 0.32); and gastroschisis (0.38). Anencephaly, cleft palate and anorectal malformation significantly decreased with a prevalence of 0.23, 0.75 and 0.54 per 1000 total births, respectively. Significantly increasing trends were reported for anotia/microtia (0.24), limb reduction anomalies (0.73), omphalocele (0.36) and Down syndrome (2.21) and for hypospadias and undescended testes (4.68 and 5.29, respectively, per 1000 male births). ConclusionCongenital anomalies are an important public health concern with significant social and societal costs. Surveillance data gathered by ACASS for over 40 years can be used for planning and policy decisions and the evaluation of prevention strategies. Contributing genetic and environmental factors are discussed as is the need for continued surveillance and research

Le système de surveillance des anomalies congénitales de l’Alberta : compte rendu des données sur 40 ans avec prévalence et tendances de certaines anomalies congénitales entre 1997 et 2019

IntroductionOn manque de données provinciales ou territoriales à long terme publiées et actuelles sur les anomalies congénitales Au Canada. Cette étude fait état de la prévalence (pour 1000 naissances totales) et des tendances pour diverses anomalies congénitales de 1997 à 2019 en Alberta (Canada). Les facteurs de risque associés sont également abordés. MethodsNous avons utilisé les données du Système de surveillance des anomalies congénitales de l’Alberta (ACASS) pour calculer la prévalence et effectuer des analyses de tendance linéaire par test du chi carré. ResultsEntre 1997 et 2019, la prévalence globale des anomalies du tube neural est demeurée stable, à 0,74 pour 1000 naissances totales. C’était également le cas pour le spina bifida (0,38), les fentes orofaciales (1,99), les cardiopathies congénitales graves (transposition des grandes artères, 0,38; tétralogie de Fallot, 0,33; hypoplasie du coeur gauche, 0,32) et le gastroschisis (0,38). L’anencéphalie, la fente palatine et les anomalies anorectales ont diminué significativement, avec une prévalence de respectivement 0,23, 0,75 et 0,54 pour 1000 naissances totales. Une tendance significativement à la hausse a été relevée pour l’anotie/microtie (0,24), les anomalies de raccourcissement des membres (0,73), l’omphalocèle (0,36) et le syndrome de Down (2,21), ainsi que pour l’hypospadias et la cryptorchidie (respectivement 4,68 et 5,29 pour 1 000 naissances masculines). ConclusionLes anomalies congénitales constituent un important problème de santé publique, qui est associé à des coûts sociaux et sociétaux substantiels. Les données de surveillance recueillies par l’ACASS sur plus de 40 ans peuvent servir à la planification et aux décisions en matière de politiques ainsi qu’à l’évaluation des stratégies de prévention. Les facteurs génétiques et environnementaux contributifs sont abordés, de même que la nécessité de poursuivre la surveillance et la recherche
