Rheumatoid arthritis rarely involves the cricoarytenoid joint. The possible consequent symptom includes hoarseness, dysphagia, odynophagia, dysfunctional dysphonia, and acute dyspnea. Etiologic diagnosis is possible with high-resolution computed tomography, which can show spacing of the articular cartilage, density and volume alterations, and subluxation of the cartilage. However, these radiologic signs are not pathognomonic for rheumatoid arthritis, and they should be combined with anamnestic data.

Curr Treatm Opt Rheumatol

Division of Rheumatology, Inflammation, and Immunity, Brigham and Women's Hospital, Boston, MA USA.
Purpose Of Review: To summarize the current treatment landscape of rheumatoid arthritis-associated interstitial lung disease (RA-ILD) in the context of the recent 2023 American College of Rheumatology/American College of Chest Physicians guideline for ILD treatment in systemic autoimmune rheumatic diseases.
Recent Findings: The guideline conditionally recommends mycophenolate, azathioprine, and rituximab for first-line RA-ILD therapy, with cyclophosphamide and short-term glucocorticoids as additional options. For RA-ILD progression after first line, mycophenolate, rituximab, nintedanib, tocilizumab, cyclophosphamide, and pirfenidone are conditionally recommended, while long-term glucocorticoids are conditionally recommended against.

This study reports the preparation of hydrogels (HG) made with xanthan gum (XG) and ƙ-carrageenan (KC) polysaccharides containing ketoprofen (KET)-loaded nanoemulsions (NK) and their evaluation in a rheumatoid arthritis (RA) model. The nano-based HGs exhibited nanometric-sized droplets (~ 100 nm), an acidic pH (5.10-6.

Background: Hyperbaric Oxygen Therapy (HBO) is a treatment modality that exposes patients to 100% oxygen at higher atmospheric pressures. Recently, HBO has emerged as a potential therapeutic option for various liver diseases, offering advantages such as improved tissue oxygenation, anti-inflammatory effects, enhanced wound healing, and potential hepatoprotective properties. Understanding the benefits of HBO in liver diseases can pave the way for novel therapeutic strategies and improved patient outcomes.

Rheumatoid arthritis (RA) is a chronic, systemic autoimmune disease characterized by chronic inflammation of the synovium and progressive joint damage. Fibroblast-like synoviocytes (FLSs) exhibit excessive proliferative and aggressive phenotypes and play a major role in the pathophysiology of RA. Previous studies have confirmed the pathologic role of L-selectin in cell adhesion and migration.

This study attempted to explore the molecular mechanism of Epimedium herb (EH) on rheumatoid arthritis (RA) treatment. We employed network pharmacology, molecular docking, and HPLC analysis to investigate the molecular mechanisms underlying the efficacy of EH in treating RA. To assess the efficacy of EH intervention, RA fibroblast-like synoviocytes (RA-FLS) and collagen-induced arthritis (CIA) mouse models were utilized.
