A Novel Technique for the Evaluation and Interpretation of Elastography in Salivary Gland Involvement in Primary Sjögren Syndrome.

Ultrasound (US) of major salivary glands (MSG) evaluates echogenicity, border features and vascularization, with elastography, it can detect tissue elasticity and glandular fibrosis, related to inflammation in Primary Sjögren's syndrome (pSS). This study aimed to develop a novel technique by pixel analysis for evaluation and interpretation of elastography in MSG in pSS. A cross-sectional and observational multicenter study was conducted.

Efficacy of leflunomide 100mg weekly compared to low dose methotrexate in patients with active rheumatoid arthritis. Double blind, randomized clinical trial.

Objective: To determine the clinical efficacy and safety of Leflunomide (LFN) 100 mg/week compared to low dose Methotrexate (MTX) 10 mg/week in a double-blind, randomized, controlled trial with 52 weeks of follow up in Rheumatoid Arthritis (RA) patients.

Patients And Methods: Patients who met ARC1987 criteria for RA were included. All patients had medical records, including laboratory tests and hand X-rays.

Chronic eosinophilic pneumonia: autoimmune phenomenon or immunoallergic disease? Case report and literature review.

Eosinophilic pneumonia is classified by its acute or chronic presentation, the distinguishing characteristics of which are based on the presence of cough, dyspnea, fever and pulmonary infiltrates with accumulation of inflammatory cells, predominantly eosinophils. The association of eosinophilia and rheumatologic disorders is well known, as in the case of eosinophilic fasciitis and the Churg-Strauss syndrome. The coexistence of chronic eosinophilic pneumonia and rheumatoid arthritis has been reported, either early rheumatoid arthritis of definitive disease.
