Coronary artery lesions in Kawasaki disease are related to gene polymorphisms
The risk of coronary artery lesions (CALs) in Kawasaki disease (KD) is related to CYP2E1 gene polymorphisms, a study from Taiwan confirmed.
Study validates new test for bacterial vs viral infections
A novel assay for distinguishing bacterial from viral infections significantly outperformed routine laboratory parameters and biomarkers in a study using serum remnants from children suspected to have acute infection.
Immediate amoxicillin is the most cost-effective choice for AOM
Using a cost-utility model of a hypothetical group of symptomatic children aged younger than 2 years who were diagnosed with acute otitis media (AOM), investigators evaluated whether antimicrobial therapy reduces time to symptom resolution, overall symptom burden, and persistence of infection.
