OBJECTIVES Sonographic artifacts known as B-lines can been used to estimate alterations of lung parenchyma. Multiple B-lines on sonography are seen in congestive heart disease, interstitial lung disease, respiratory infections, and neonates. The aim of this study was to compare the amount of B-lines on sonography to the extent of parenchymal changes on(More)
BACKGROUND Delayed postnatal removal of lung liquid may result in respiratory distress, which is more common in infants born by cesarean section. Vertical artefacts (B-lines) arising from the lung surface in lung ultrasound have been shown to correlate with the liquid content of the lungs. OBJECTIVES We studied whether lung ultrasound could be used for(More)
AIM To determine the usefulness of magnetic resonance enterography (MRE) in treatment for paediatric patients with Crohn's disease. METHODS To evaluate small bowel involvement, 45 children with Crohn's disease were scheduled for MRE. Two radiologists blinded to the patient data independently re-evaluated the images. Findings in images were compared to(More)
BACKGROUND B-lines in lung ultrasound can be used to estimate lung liquid. B-lines are ring-down artifacts that arise from alterations to subpleural lung parenchyma. Lung ultrasound has been used to differentiate between diseases causing respiratory symptoms in neonates. B-lines are also seen in healthy infants during postnatal adaptation. Static lung(More)
OBJECTIVE Ambient hypoxia impairs the airway epithelial Na transport, which is crucial in lung edema reabsorption. Whether chronic systemic hypoxemia affects airway Na transport has remained largely unknown. We have therefore investigated whether chronic systemic hypoxemia in children with congenital heart defect affects airway epithelial Na transport, Na(More)
BACKGROUND Lung ultrasounds show vertical artifacts known as B-lines in the presence of increased extravascular lung water (EVLW). We aimed to investigate whether lung ultrasound could estimate EVLW after congenital cardiac surgery. METHODS This prospective observational study comprised 61 children (age range 3 days to 7.4 years) undergoing congenital(More)
