We describe a case of chronic tenosynovitis in the hand of a 58-year-old cattle farmer. Surgical biopsy specimens grew Mycobacterium arupense. The patient responded to surgery and antimicrobial therapy based on in vitro susceptibility testing. The antimicrobial susceptibility profiles of the isolate from this patient and 39 additional clinical isolates are presented.

Remitting Seronegative Symmetrical Synovitis with Pitting Edema (RS3PE) is an uncommon elderly-onset rheumatic picture descripted for the first time by McCarthy et al. in 1985 [1] characterized by tenosynovitis of extensor tendons at the wrist and (less frequently) at the feet. The edematous imbibition of tendon sheaths determines the “boxing-glove" swelling which can be considered when bilater...

BACKGROUND As an irreversible disease, a treatment delay can negatively affect treatment response in rheumatoid arthritis (RA). Ultrasound and MRI have played an important role in assessing disease progression and response to treatment in RA for many years. The present study was designed to compare the diagnostic efficacy of ultrasound grading and MRI in early RA. METHODS In this retrospectiv...

C ompared with monoarticular arthritis, polyarticular arthritis may yield an initially narrower differential diagnosis that focuses on systemic inflammatory conditions, such as rheumatoid arthritis (RA). Approximately 15% to 30% of septic arthritis is polyarticular, of which about 45% is associated with underlying RA.1,2 Regardless of the number of joints involved, septic (infectious) arthritis...

BACKGROUND AND OBJECTIVES Although morning stiffness has long been recognized as a characteristic feature of rheumatoid arthritis (RA), it is no more included in the 2010 ACR/EULAR Classification Criteria or in the current major instruments for evaluating disease activity of RA. In this cross-sectional study, we aimed to determine the independent value and the optimal measurement of morning sti...

Background. Tenosynovitis is widely accepted to be common in rheumatoid arthritis (RA) and postulated to be the first manifestation of RA, but its true prevalence in early disease and in particular the hand has not been firmly established. The aims of this study were first to investigate the frequency and distribution of finger flexor tenosynovitis using ultrasound in early arthritis, second to...

OBJECTIVE To describe the effect of customized foot orthoses (FOs) on the kinematic, kinetic and EMG features in patients with RA, tibialis posterior (TP) tenosynovitis and associated pes plano valgus. METHODS Patients with RA and US-confirmed tenosynovitis of TP underwent gait analysis, including three-dimensional (3D) kinematics, kinetics, intramuscular EMG of TP and surface EMG of tibialis...
