CT-abnormalities, bacteriology and symptoms of sinonasal disease in children with Cystic Fibrosis

Sinonasal pathology in adults with Cystic Fibrosis (CF) is common but the extent of CT-abnormalities and symptoms of sinonasal disease in children with CF and the age of onset are less frequently studied. In this observational, cross-sectional study 58 children with CF from two CF centres were included. All subjects completed a questionnaire regarding sinonasal symptoms, underwent a CT scan of the paranasal sinuses, and in each subject a culture of the upper airways was performed. Subjects were divided in 6 age cohorts (0-2, 3-5, 6-8, 9-11, 12-14 and 15-17years) and were divided into severe and mild CF based on their CFTR mutation. Opacification of the sinonasal system of the subjects was compared with opacification on MRI-scans of an age-matched control group without CF. Most frequently reported symptoms were nasal obstruction and posterior/anterior nasal discharge. Opacification was abundant in every age cohort of the study group and was significantly more compared to the control group. In patients with severe CF the opacification was higher than subjects with mild CF. Upper airway cultures showed predominantly Staphylococcus aureus, Haemophilus influenzae and Pseudomonas aeruginosa. CT-abnormalities indicating sinonasal disease and symptoms are present from shortly after birth which may argue for a thorough examination of the upper airways in children with C

Sacral abnormalities including caudal appendage, skeletal dysplasia, and prenatal cardiomyopathy associated with a pathogenic TAB2 variant in a 3-generation family

Haplo-insufficiency of the TGF beta-activated kinase 1 binding protein 2 (TAB2) gene is associated with short stature, facial dysmorphisms, connective tissue abnormalities, hearing loss, and cardiac disease. Skeletal dysplasia and sacral dimples are also found in a minority of patients. Here, we describe a 3-generation family with caudal appendage, other sacral anomalies, and skeletal abnormalities including hypoplasia of the iliac wings and scapulae, fusion of the carpal bones and stenosis of the spinal canal, as well as a remarkable course of prenatally-detected cardiomyopathy with characteristics changing over time. Genetic analysis showed a heterozygous nonsense variant in the TAB2 gene.Otorhinolaryngolog
