Using a whole-exome sequencing strategy, we identified recessive CCNO (encoding cyclin O) mutations in 16 individuals suffering from chronic destructive lung disease due to insufficient airway clearance. Respiratory epithelial cells showed a marked reduction in the number of multiple motile cilia (MMC) covering the cell surface. The few residual cilia that(More)
IL-6 plays a central role in supporting pathological T(H2) and T(H17) cell development and inhibiting the protective T regulatory cells in allergic asthma. T(H17) cells have been demonstrated to regulate allergic asthma in general and T-bet-deficiency-induced asthma in particular. Here we found an inverse correlation between T-bet and Il-6 mRNA expression(More)
BACKGROUND Diffuse parenchymal lung diseases (DPLD) in children represent a rare and heterogeneous group of chronic pulmonary disorders. Despite substantial advances in enetics and pathomechanisms, these often lethal diseases are still under-diagnosed. This is due to the fact that (i) the incidence is low, and (ii) clinical presentation, (iii) disease(More)
Diagnostic and treatment modalities have changed substantially over the past years in the field of pediatrics and neonatal medicine. As a result, the indications and outcome after tracheostomy in young patients have evolved. The aim of this study is to present our experience with pediatric tracheostomies and provide an up-to-date review of the literature(More)
Clinical evaluation and mutation analysis was performed in 51 consecutive probands with severe eye malformations - anophthalmia and/or severe microphthalmia - seen in a single specialist ophthalmology center. The mutation analysis consisted of bidirectional sequencing of the coding regions of SOX2, OTX2, PAX6 (paired domain), STRA6, BMP4, SMOC1, FOXE3, and(More)
BACKGROUND Mice without the basic leucine zipper transcription factor, ATF-like (BATF) gene (Batf(-/-)) lack TH17 and follicular helper T cells, which demonstrates that Batf is a transcription factor important for T- and B-cell differentiation. OBJECTIVE In this study we examined whether BATF expression would influence allergic asthma. METHODS In a(More)
X-linked hypohidrotic ectodermal dysplasia (XLHED; ectodysplasin deficiency) has been classically described as affecting hair, sweat glands, and dentition. What may be underappreciated is the effect ectodysplasin deficiency has on glands surrounding the airways and eyes and the resulting chronic health issues. In this study, 12 male children (age range 6–13(More)
To the Editor: The majority of viral infections of the airways are associated with asthma exacerbations in children. Two thirds of these viral infections are caused by rhinovirus, and hospital admissions for asthma correlate with the seasonal peak of rhinovirus infections. TGF-b is a cytokine known to induce forkhead box P3 (FoxP3) regulatory T (Treg) cells(More)
OBJECTIVE Physical activity is an important and frequent trigger of airways obstruction in asthmatic children. We aimed to compare the efficacies of 50 microg salmeterol twice daily and 2 mg SCG four times daily with respect to protection from exercise induced bronchoconstriction (EIB). METHODS Twenty seven children and adolescents aged 4 to 16 years with(More)
