Remitting Seronegative Symmetrical Synovitis With Pitting Edema in an Adolescent

Remitting seronegative symmetrical synovitis with pitting edema (RS3PE) is a rare clinical entity characterized by symmetrical tenosynovitis of both hands and ankles with pitting edema, negative rheumatoid factor (RF), absence of radiographic erosions, and excellent response to low-dose steroids. It is classically associated with elderly patients but may occur in younger patients, with only one case reported in the pediatric age. We report a case of RS3PE diagnosed in a pediatric patient.

Long COVID in Children and Adolescents: A Retrospective Study in a Pediatric Cohort

Studies on long coronavirus disease (COVID) in children are scarce. We aimed to describe persistent symptoms and identify risk factors for its development.

Chronic conditions and obesity were risk factors, and adolescents were at a greater risk for long COVID.
