Ultrasound's role in differentiating camptodactyly-arthropathy-coxa vara-pericarditis (CACP) syndrome from inflammatory arthritis in children. A narrative review.

Camptodactyly-arthropathy-coxa vara-pericarditis (CACP) syndrome is a rare genetic disorder characterized by a combination of congenital flexion contractures of the fingers (camptodactyly), non-inflammatory joint swelling (arthropathy), hip deformities (coxa vara), and recurrent pericarditis. In early childhood, the clinical presentation is dominated by the articular manifestations that can easily mimic juvenile idiopathic arthritis, often leading to delayed diagnosis and inappropriate treatments. Although not pathognomonic, ultrasound may provide specific ultrasound characteristics of joint involvement in CACP syndrome that help differentiate it from inflammatory arthropathies.

New Diagnoses of Juvenile Idiopathic Arthritis Early in the COVID-19 Pandemic: Analysis of a Large United States Commercial Insurance Database.

Radiographs in Pediatric Rheumatology: Where Do We Stand?

Rheumatic disorders in children include inflammatory arthritis, inflammatory bone disorders such as chronic nonbacterial osteomyelitis (CNO), connective tissue disorders, and vasculitides (juvenile dermatomyositis, scleroderma). The diagnosis in these children is based on a combination of history, clinical examination, and laboratory investigations. Radiographs play an important role in children with arthritis, who have atypical presentation or for assessment of disease-related damage and differentiation from mimics.

Consensus on transition care for juvenile idiopathic arthritis: a Delphi study with youth, caregivers, and health professionals.

Background: The field of transitional care for chronic conditions in adolescents, notably juvenile idiopathic arthritis (JIA), is rapidly growing. Transitioning these patients to adult healthcare systems presents significant challenges in practical implementation. Consequently, it would be appropriate for each country to develop a transition program tailored to its specific infrastructure.

New onset heart failure in adolescents with inflammatory joint disease treated with TNF-α inhibitors: a case-based review.

The safety of tumor necrosis factor (TNF) inhibitors has been demonstrated for over two decades. However, their effects on cardiovascular function in patients with rheumatic diseases remain controversial, and conclusions are additionally hampered by the cardiovascular complications inherent in such diseases. We present two 15-year-old patients diagnosed with ankylosing spondylitis and juvenile idiopathic arthritis classified as polyarthritis with positive rheumatoid factor, respectively.

Maximal mouth opening is a simple method to evaluate the treatment outcome of temporomandibular joint arthritis in patients with juvenile idiopathic arthritis.

Objective: Temporomandibular joint (TMJ) arthritis is a common finding in juvenile idiopathic arthritis (JIA) patients. TMJ arthritis can cause significant disturbances in TMJ function and growth without treatment. Our aim was to evaluate the effectiveness of medical treatments used to manage TMJ arthritis and how to evaluate the outcome of the treatment.

Understanding network meta-analysis.

Recently, in the , studied the different non-steroidal anti-inflammatory drugs (meloxicam, celecoxib, naproxen, and rofecoxib) for juvenile idiopathic arthritis with network meta-analysis (NMA). This manuscript aims to introduce to clinicians what NMA is. NMA represents a fundamental technique for simultaneously comparing three or more interventions within a single analysis, harnessing both direct and indirect evidence derived from a network of studies.

Single-Centre Analysis of Magnetic Resonance Imaging of Sacroiliac Joints in a Paediatric Population.

Sacroiliitis in children is usually connected with one of the subtypes of juvenile idiopathic arthritis (JIA), such as enthesitis-related arthritis, psoriatic arthritis, or undifferentiated arthritis. The main diagnostic method is magnetic resonance imaging (MRI) of the sacroiliac joints, which can reveal bone marrow edema (BME) as a sign of an active inflammation process. This research aimed to retrospectively investigate the associations between the clinical presentation, laboratory test results, and MRI results of the sacroiliac joints of children.

Fetal Growth Associated with Maternal Rheumatoid Arthritis and Juvenile Idiopathic Arthritis.

Patients with rheumatoid arthritis (RA) and juvenile idiopathic arthritis (JIA) are at a twice-higher risk of developing adverse pregnancy outcomes, such as preterm births and infants with a low birth weight. We aimed to evaluate fetal growth among patients with and without rheumatoid arthritis and juvenile idiopathic arthritis (RA and JIA). We conducted a population-based cohort study in Denmark from 2008-2018, which included 503,491 singleton pregnancies.
