Patients Without a Rheumatic Disease Diagnosis in a Pediatric Rheumatology Unit: Retrospective Analysis and Comparison Between Pre-pandemic and Pandemic Periods.

Objective: Children with suspicious complaints of rheumatic diseases are generally referred to a pediatric rheumatologist. We aimed to evaluate the profile of patients referred to the pediatric rheumatology unit and were not diagnosed with a rheumatic disease and to assess the impact of the coronavirus disease-2019 pandemic on referral complaints.

Materials And Methods: All new outpatients who applied to the pediatric rheumatology department between March 2019 and February 2021 and were not diagnosed with rheumatic disease were included.

Clinical features and outcomes of opsoclonus myoclonus ataxia syndrome.

Results: There were 14 boys and 9 girls aged 4-113 months, median 24 months.

Rice bodies in children with rheumatic disorders: A case series and systematic literature review.

Objectives: Rice body (RB) formation is an uncommon inflammatory process seen in systemic disorders. In this study, we aimed to assess characteristic features of RBs in pediatric patients.

Method: We retrospectively evaluated pediatric patients who underwent joint/extremity magnetic resonance imaging.
