Observational Study
Clinical features of severe pediatric patients with coronavirus disease 2019 in Wuhan: a single center's observational study.
An outbreak of coronavirus disease 2019 (COVID-19) caused by SARS-CoV-2 was first detected in Wuhan, Hubei, China. People of all ages are susceptible to SARS-CoV-2 infection. No information on severe pediatric patients with COVID-19 has been reported. We aimed to describe the clinical features of severe pediatric patients with COVID-19. ⋯ In this series of severe pediatric patients in Wuhan, polypnea was the most common symptom, followed by fever and cough. Common imaging changes included multiple patch-like shadows and ground-glass opacity; and a cytokine storm was found in these patients, which appeared more serious in critically ill patients.

Diffusion-weighted imaging (DWI) of synovitis has been suggested as a possible non-invasive alternative to contrast-enhanced T1w imaging (ce-T1w). We aimed to study DWI for diagnosing synovitis in the knee joint of pediatric patients, to quantify inter-observer agreement on DWI and ce-T1w and to calculate quantitative measures of synovial diffusivity and conspicuity. ⋯ Diffusion-weighted imaging is a promising, though reader-dependent alternative to contrast-enhanced imaging in patients with arthritis of the knee, based on our preliminary findings. It holds potential for increasing patient safety and comfort.

Pediatric patients with croup are frequently admitted if they require two doses of racemic epinephrine (RE) in the emergency department (ED). We aimed to identify factors associated with the need for additional therapy (> 2 RE doses) among pediatric patients with croup. ⋯ Patients hospitalized for croup with recent use of steroids prior to ED presentation have a greater need for > 2 RE during hospitalization. The majority who require inpatient RE will do so within 8-12 hours. These data provide information for risk stratification and duration of monitoring for patients hospitalized with croup.

Biomarkers of intravenous immunoglobulin resistance and coronary artery lesions in Kawasaki disease.
Currently, there are no reliable indicators for predicting intravenous immunoglobulin resistance and coronary artery lesions in the early stage of Kawasaki disease. ⋯ Elevated serum ferritin, globulin and D-dimer levels are significantly associated with intravenous immunoglobulin resistance in Kawasaki disease. Moreover, serum D-dimer is significantly increased in Kawasaki disease with coronary artery lesions.
