Abstract Background/Aims Conventional synthetic disease-modifying anti-rheumatic drugs (csDMARDs) remain a cornerstone in managing chronic inflammatory rheumatic diseases by slowing disease progression and improving patients’ quality of life. These are often prescribed to women childbearing age, raising concerns about their safety management during pregnancy. Although guidelines exist regarding the use csDMARDs pregnancy, they sometimes insufficient, clinical practices among rheumatologists...

Reactive arthritis is a rare form of spondyloarthropathies occurring after genital or enteric infection. It most often self-limited but can progress to chronic spondylarthritis. We report the case 30-year-old man who presented with acute 2 months an episode urethral discharge. Physical examination revealed polyarthritis, dactylitis, sacroiliac joint involvement, and plantar papulosquamous plaques. The human leukocyte antigen B27 was positive. Detection

Foot function is usually assessed using self-reported outcome measures which remain subjective in patients with rheumatoid arthritis (RA). Physical performance tests were recommended for functional assessment lower limb osteoarthritis. However, foot assessment's guidelines RA are lacking. We aimed to investigate the correlation between a measure and two performance-based physical assessing patients.A cross-sectional study was performed over 7 months' period including patients. used...
