This was a cross-sectional study of the measured level of PA in children with JIA, compared with age- and gender-matched healthy schoolchildren. PA was estimated using a physical activity questionnaire for children and for adolescents (cPAQ/aPAQ). Disease activity was evaluated with the Juvenile Arthritis Disease Activity Score (JADAS). Functional ability was assessed with the Childhood Health Assessment Questionnaire (CHAQ). A total of 55 children with JIA and 55 healthy control schoolchildren were included. Children with JIA had significantly lower levels of PA compared with their healthy peers as assessed with the cPAQ/aPAQ (P=0.0121). In total, 76% of the JIA group spent the day sleeping and sitting, which was significantly higher compared with the reference group (P=0.001 and P=0.055, respectively). Low PA level was associated with systemic JIA (P=0.002, OR=2.123), polyarticular JIA with positive rheumatoid factor (P=0.001, OR=2.014), JADAS-27≥6 (P=0.001, OR=2.524), patients undergoing treatment (P=0.001, OR=1.271), and higher CHAQ (P=0.002, OR=2.461). Children with JIA were less physically active than their healthy peers and less active than recommended for general health. Children with JIA were less physically active than their healthy peers and less active than recommended for general health.Beta thalassemias are autosomal recessive hemoglobin disorders related to a defect in the beta-globin chain production. Most of the major forms of beta-thalassemia are transfusion dependent leading to iron overload. Today, three iron chelators are available in France. We report the case of a patient suffering from β+ major transfusion-dependent thalassemia who presented with severe skin reactions to deferoxamine and deferasirox as well as with agranulo
