Risk factors and scores for prediction of coronary artery aneurysms in Kawasaki disease: a European monocentric study.

Background: Japanese Kawasaki disease (KD) risk scores cannot be adopted in non-Japanese patients. In North American populations a baseline coronary artery Z-score > 2 and the Son score are associated with coronary artery aneurysms (CAAs) at 4 and 8 weeks from disease onset. In European populations, the Kawanet and Kawanet-echo scores are associated with intravenous immunoglobulin resistance.

Development of a score for early identification of children with Kawasaki disease requiring second-line treatment in multi-ethnic populations in Europe: A multicentre retrospective cohort study.

Background: Early identification of high-risk patients is essential to stratify treatment algorithms of Kawasaki disease (KD) and to appropriately select patients at risk for complicated disease who would benefit from intensified first-line treatment. Several scores have been developed and validated in Asian populations but have shown low sensitivity in predicting intravenous immunoglobulin (IVIG) resistance in non-Asian populations. We sought methods to predict the need for secondary treatment after initial IVIG in non-Asian populations.

A Comparative Study of Febrile Seizures and Febrile Convulsions Associated With Mild Gastroenteritis.

Background: Children presenting with complex febrile seizures (FS) have an increased risk of developing epilepsy. This study aimed to investigate the occurrence of complex seizures in children presenting with FS and those with both convulsions associated with mild gastroenteritis (CwG) and fever.

Methods: Children admitted to our Pediatric Emergency Department between January 2017 and April 2019 with seizures were enrolled in this cross-sectional study.

Infection-Triggered Hyperinflammatory Syndromes in Children.

An association between infectious diseases and macrophage activation syndrome (MAS) has been reported, yet the exact role of infection in MAS development is still unclear. Here, a retrospective analysis of the clinical records of patients with rheumatic diseases complicated with MAS who were treated in a pediatric tertiary care center between 2011 and 2020 was performed. Any infection documented within the 30 days preceding the onset of MAS was reported.
