Objective: Inconsistent assessment and treatment may impair juvenile idiopathic arthritis (JIA) outcomes. We aimed to improve polyarticular JIA (rheumatoid factor-positive and -negative) outcomes by standardizing point-of-care disease activity monitoring and implementing clinical decision support (CDS) to reduce treatment variation.
Methods: We performed a quality improvement initiative in an outpatient pediatric rheumatology practice. The interventions, implemented from April to November 2016, included standardized disease activity measurement, disease activity target review, and phased introduction of polyarticular JIA CDS to guide medication selection, dosing, treatment duration, and tapering. Process measures included visit-level target attestation (goal: 50%) and CDS use (goal: 15%). Our goal was to reduce the polyarticular JIA clinical Juvenile Arthritis Disease Activity Score (cJADAS-10) by at least 10%. Included patients had at least 2 visits from April 2016 through July 2017, and were classified as having early (≤ 6 mos) or established disease (> 6 mos).
Results: Patients with polyarticular JIA (n = 97; 81% established disease) were observed for 10.3 months (interquartile range: 6.4-12.3). Target attestation and CDS use occurred in a mean of 77% and 45% of polyarticular JIA visits, respectively. The median cJADAS-10 decreased significantly in both early (16.5 to 2.7, p < 0.001) and established polyarticular JIA (2.1 to 1.0, p = 0.01). A high proportion of patients with early disease received biologic therapy (73.7%). In established disease, although prescription of nonbiologic and biologic disease-modifying antirheumatic drugs remained similar overall, adalimumab prescribing increased (12.8% to 23.1%, p = 0.008).
Conclusion: Implementation of structured disease activity monitoring and CDS in polyarticular JIA was associated with significant reductions in disease activity scores in both early and established disease.

Background: Juvenile idiopathic arthritis (JIA), superseding juvenile rheumatoid arthritis (JRA), is a chronic autoimmune disease affecting children and characterized by various types of childhood arthritis. JIA manifests clinically with joint inflammation, swelling, pain, and limited mobility, potentially leading to long-term joint damage if untreated. This study aimed to identify genes associated with the progression and prognosis of JIA polyarticular to enhance clinical diagnosis and treatment.

Objective: Juvenile idiopathic arthritis (JIA) is a common, chronic and inflammatory rheumatological disease of childhood. The disease can affect all synovial joints in the body. Temporomandibular joints (TMJs) are important areas of involvement in JIA, which are frequently involved but often not noticed because the involvement is usually asymptomatic.

Article Synopsis
- Juvenile idiopathic arthritis (JIA) is a common childhood illness, with the polyarticular type affecting 63-66% of patients, and this study focused on its direct medical costs in a Mexican hospital.
- Analyzed records from January to September 2022 revealed that the average medical cost for a patient over the first 10 years of treatment was approximately $4,555, with medications constituting 82.7% of these costs, primarily from biological disease-modifying drugs (bDMARDs).
- The study concluded that the high cost of bDMARDs significantly impacts treatment expenses and suggested exploring generic options and negotiating prices to reduce overall costs for health institutions in Mexico.

Article Synopsis
- The study aimed to apply the PRINTO classification system for diagnosing Juvenile Idiopathic Arthritis (JIA) specifically among Mexican patients, assessing various demographic, clinical, and laboratory factors.
- In a cross-sectional analysis of 76 JIA patients, a reclassification using PRINTO showed significant alignment with categories like systemic JIA (sJIA) and RF positive polyarticular JIA, revealing variations particularly in RF negative polyarticular JIA.
- The findings highlighted a high prevalence of antinuclear antibodies (ANAs) in patients, but only a few were diagnosed with early onset ANAs positive JIA, indicating the need for further evaluation in distinguishing JIA subtypes.

Pachydermodactyly, an uncommon variant of digital fibromatosis, predominantly affects young men and results in fibrous swelling on the sides of the proximal interphalangeal joints. It is generally considered benign and asymptomatic, requiring only regular follow-up. Nevertheless, the absence of established diagnostic criteria has led to misdiagnoses, prompting the administration of unnecessary medications.
