This is an original report of a 75-year-old woman suffering from multicentric Castleman's disease associated with a destructive polyarthritis, which do not correspond to any known rhumatologic disease. Cattleman's disease (angiofollicular lymph node hyperplasia) is a lymphoproliferative disorder of unknown etiology. Two forms are described: a localized and a multicentric. In the literature, associations of Cattleman's disease and connective tissue disease such as rheumatoid arthritis have been described. Association with POEMS syndrome (polyneuropathy, organomegaly, endocrinopathy, M component, skin changes) and amylosis have also been described.

Cartilage destruction in juvenile idiopathic arthritis (JIA) is diagnosed, often too late, on basis of clinical evaluation and radiographic imaging. This case-control study investigated serum chondroitin/dermatan sulfate (CS/DS) as a potential biochemical marker of cartilage metabolism, aiming to improve early diagnosis and precision treatment for JIA. We also measured the levels of insulin-like growth factor-1 (IGF-1) and insulin-like growth factor-binding protein-3 (IGFBP-3) (using ELISA methods) in JIA patients ( = 55) both before and after treatment (prednisone, sulfasalazine, methotrexate, administered together), and analyzed their relationships with CS/DS levels.

Objective: To identify factors associated with the absence of cervical spine instability in patients with rheumatoid arthritis (RA).
Methods: Cervical spine instability was defined as the presence of at least one of the following: atlantoaxial subluxation, vertical subluxation of the axis, or subaxial subluxation. In 2001-2002, 634 enrolled outpatients with "classical" or "definite" RA underwent a radiographic cervical spine checkup.

Objectives: Septic arthritis after anterior cruciate ligament (ACL) reconstruction is a rare but potentially devastating complication. The imaging findings associated with such infections are not well-described or quantified. The purpose of this study was to describe and quantify the frequency of the characteristic MRI findings of infection following ACL reconstruction.

Rheumatoid arthritis (RA) is a chronic autoimmune disease characterized by persistent inflammation of the synovial joints, leading to cartilage and bone destruction. This study aimed to evaluate the diagnostic utility of specific microRNAs (miRNAs) as potential biomarkers for RA. The study was conducted on 60 patients with RA disease along with 20 control participants.

Rheumatoid arthritis (RA) is characterized by synovial hyperplasia and cartilage/bone destruction. RA affects the synovial joints, the synovial lining and the permeability of the synovium. As the latter is of central relevance for the distribution of systemically delivered therapeutics into synovial fluid (SF), we here assessed the protein composition of paired plasma and SF of patients diagnosed with RA at three distinct levels of depth using mass spectrometric approaches: the "total" proteome, the "total" IgG1 antibody repertoire and the RA-specific ACPA IgG1 autoantibody repertoire.
