CASE: We present a case of rice-body formation and partial flexor tendon rupture in a 3-year-old child with seronegative juvenile idiopathic arthritis (JIA), which presented as a painless soft-tissue mass of the volar aspect of the hand. The diagnosis was not confirmed until histologic examination. The patient was managed with a tenosynovectomy and oral medication; he made a full recovery. CONCLUSION: JIA is one of the most common rheumatologic conditions of childhood...

Interleukin-6 (IL-6) is implicated in the pathogenesis of both systemic juvenile idiopathic arthritis (SJIA) and syndrome of inappropriate secretion of antidiuretic hormone (SIADH), but the 2 have not been previously described as occurring together. We report a case of a 6-year-old girl with symptoms of arthralgia, daily fevers, evanescent rash, lymphadenopathy, and laboratory evaluation showing elevated inflammatory markers, consistent with SJIA. At presentation, the patient had hyponatremia with a sodium level of 128 mEq/L...

Objective: JIA is an autoimmune, inflammatory disease with involvement of innate and adaptive immune responses. However, the role of neutrophils in JIA pathogenesis remains unclear. This study aimed to identify and validate neutrophil gene expression signatures in JIA using public microarray datasets and new clinical samples. Methods: Three suitable datasets were analysed by significance analysis of microarray and Ingenuity. Neutrophils and peripheral blood mononuclear cells (PBMCs) were isolated from a new cohort of JIA patients and healthy paediatric controls (HCs)...

BACKGROUND: Knowledge of normal appearances of the temporomandibular joint (TMJ) is paramount when assessing the joint for disease in juvenile idiopathic arthritis. Reliable features defining normal TMJs in children are limited. OBJECTIVE: To establish reliable normal standards for the TMJ at magnetic resonance imaging (MRI). MATERIALS AND METHODS: We included children and young adults aged 2-18 years undergoing a head MRI for reasons not believed to affect the TMJs...

OBJECTIVES: Anti-tumor necrosis factor alpha (anti-TNF-α) agents are generally well tolerated, yet they can be associated with serious adverse events (SAEs) in a minority of patients. We examined the incidence of SAEs in a pediatric referral center for chronic rheumatologic and gastroenterological inflammatory disorders. METHODS: Retrospective analysis of SAEs occurring during treatment with anti-TNF-α agents in patients with juvenile idiopathic arthritis (JIA) (n = 78)  or pediatric-onset inflammatory bowel disease (IBD) (n = 105) seen at the Institute for Maternal and Child Health IRCCS "Burlo Garofolo" in Trieste, Italy, between June 2001 and February 2016...

Synovial fluid (SF) is a protein-rich fluid produced into the joint cavity by cells of the synovial membrane. Due to its direct contact with articular cartilage, surfaces of the bone, and the synoviocytes of the inner membrane, it provides a promising reflection of the biochemical state of the joint under varying physiological and pathophysiological conditions. This property of SF has been exploited within numerous studies in search of unique biomarkers of joint pathologies with the ultimate goal of developing minimally invasive clinical assays to detect and/or monitor disease states...

PURPOSE OF REVIEW: Aberrant epigenetic changes in DNA methylation, histone marks, and noncoding RNA expression regulate the pathogenesis of many rheumatic diseases. The present article will review the recent advances in the epigenetic profile of inflammatory arthritis and discuss diagnostic biomarkers and potential therapeutic targets. RECENT FINDINGS: Methylation signatures of fibroblast-like synoviocytes not only distinguish rheumatoid arthritis (RA) and osteoarthritis (OA), but also early RAs from late RAs or juvenile idiopathic arthritis...

REVIEW
Sriharsha Grevich, Susan Shenoi
Systemic juvenile idiopathic arthritis (SJIA) is a disease marked with arthritis and several features of systemic inflammation including fevers, rashes, hepatosplenomegaly, lymphadenopathy, and serositis. The presentation can be variable and arthritis can be a later feature. Macrophage activation syndrome can be a life-threatening complication of this illness and requires early recognition and prompt therapy. Advancements in understanding the biology of SJIA have led to the development of cytokine-targeted therapies, mainly interleukin-1 (IL-1) and IL-6 inhibitors that have significantly improved outcomes...

OBJECTIVES: Pain is a very common symptom of juvenile idiopathic arthritis (JIA). Disease activity alone cannot explain symptoms of pain in all children, suggesting other factors may be relevant. The objectives of this study were to describe the different patterns of pain experienced over time in children with JIA and to identify predictors of which children are likely to experience ongoing pain. METHODS: This study used longitudinal-data from patients (aged 1-16 years) with new-onset JIA...

BACKGROUND AND PURPOSE: MR imaging has been shown to be useful in the diagnosis of juvenile idiopathic arthritis of the temporomandibular joint. Prior MR imaging approaches have relied mainly on the subjective interpretation of synovial enhancement as a marker for synovial inflammation. Although, more recently, several attempts have been made to quantify synovial enhancement, these methods have not taken into account the dynamic enhancement characteristics of the temporomandibular joint and the effect of sampling time...
