Nerve sonography in the diagnostic evaluation of primary and secondary carpal tunnel syndrome in rheumatoid arthritis.

Background And Purpose: Carpal tunnel syndrome (CTS) is the most common entrapment neuropathy and extra-articular manifestation of rheumatoid arthritis (RA). However, in patients with RA, it is not always possible to clinically distinguish an actual CTS from other RA-based complaints.

Methods: We evaluated the diagnostic role of nerve ultrasound (NUS) as supportive tool in the diagnostic process of CTS in patients with RA and tried to provide etiological clarification in cases of secondary CTS.

The Structured Delegation of Medical Care Services for Patients With Inflammatory Rheumatic Diseases.

Background: In some areas of Germany, there is a shortage of specialist physicians for patients with inflammatory rheumatic diseases. Delegating certain medical care services to qualified, specialized rheumatological assistants (SRAs) might be an effective way to supplement the available capacity for specialized medical care.

Methods: Patients under stable treatment for rheumatoid arthritis (RA) or psoriatic arthritis (PsA) were included in this trial, which was designed to demonstrate, in a first step, the non-inferiority of a form of care involving delegation of physicians' tasks to SRAs (team-based care), in comparison to standard care, with respect to changes in disease activity at one year.

Diagnostic value of a 3-day course of prednisolone in patients with possible rheumatoid arthritis - the TryCort study.

Background: In patients with tender and swollen finger joints, the differential diagnosis between rheumatoid arthritis (RA) and osteoarthritis (OA) of the hands can be initially difficult. This prospective study (the TryCort study) was performed to study the diagnostic value of prednisolone in differentiating between RA and hand OA. We present the results of this potentially diagnostic test in patients with possible RA in daily clinical practice by demonstrating the results of a pilot and a validation part of this 'prednisolone test' (pred-test).

Monitoring ankylosing spondylitis: clinically useful markers and prediction of clinical outcomes.

Patient assessment in axial spondyloarthritis (axSpA) is multidimensional, and monitoring of disease activity, function and radiographic progression is complex. There is no simple 'gold standard' for measuring disease activity in all individual patients, as disease activity in axSpA is the sum of many different aspects and a complexity that cannot be represented by a single variable. Limited spinal mobility is a cardinal sign of ankylosing spondylitis and loss of spinal mobility has been reported to be a prognostic factor and most often evaluated with the Bath Ankylosing Spondylitis Functional Index.
