Prolonged Thrombocytopenia in a Case of MIS-C in a Vaccinated Child.

Multisystem inflammatory syndrome in children (MIS-C) has been extensively described in patients following severe acute respiratory syndrome coronavirus 2 infection. There are now questions about what MIS-C may look like in vaccinated children. Multisystem inflammatory syndrome in children has many clinical and laboratory features in common with other inflammatory disorders including Kawasaki disease and toxic shock syndrome.

Intraarticular steroids as DMARD-sparing agents for juvenile idiopathic arthritis flares: Analysis of the Childhood Arthritis and Rheumatology Research Alliance Registry.

Background: Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months.

Exercise-Induced Purpura in Children.

Exercise-induced purpura, which has also been called "golfer's purpura," is a phenomenon that has been rarely reported in the pediatric literature. This is the first case series in which this benign vasculopathy, which is most often associated with warm weather and high-impact activity, is described. In this series, we describe 5 patients, most of whom had an erythematous purpuric rash above the sock line that extended to the knees and was associated with warm weather and prolonged activity.

Improvement of medication adherence in adolescents and young adults with SLE using web-based education with and without a social media intervention, a pilot study.

Background: Self-management skills, including medication management, are vital to the health of adolescents and young adults with systemic lupus erythematosus (SLE). The purpose of this study was to assess the feasibility and preliminary effects of an online educational program in a cohort of adolescent and young adults with SLE with and without a social media (SM) experience.

Methods: Adolescents and young adults with SLE participated weekly for 8 sessions on a web-based educational program about SLE created specifically for this project.
