Bibliometric studies concerning the quantity and quality of articles published in rheumatology journals are scarce. This study aims to compare scientific production in the field of rheumatology between countries and evaluate the publication trend and citations worldwide. ⋯ The USA and Western Europe clearly dominate the production of scientific publications in rheumatology. However, some smaller European countries have high scientific output relative to their size.

Catastrophic antiphospholipid syndrome (CAPS) is a life-threatening disease caused by the onset of rapidly progressive and widespread small-vessel thromboses in the presence of aPLs. The aim of this study was to examine pregnancy-related CAPS. ⋯ The occurrence of HELLP syndrome in a patient with APS should raise the suspicion of CAPS in the following days, and anticoagulation should be maintained post-partum or post-abortum. Subsequent pregnancies are at very high risk.

Comparative Study
Tactile acuity is disrupted in osteoarthritis but is unrelated to disruptions in motor imagery performance.
To determine whether tactile acuity is disrupted in people with knee OA and to determine whether tactile acuity, a clinical signature of primary sensory cortex representation, is related to motor imagery performance (MIP; evaluates working body schema) and pain. ⋯ In painful knee OA, tactile acuity at the knee is decreased, implying disrupted representation of the knee in primary sensory cortex. That TPD and MIP were unrelated in knee OA, but related in back pain, suggests that the relationship between them may vary between chronic pain conditions. That pain was not related to TPD threshold nor MIP suggests against the idea that disrupted cortical representations contribute to the pain of either condition.

Chronic pain from rheumatic and musculoskeletal conditions is associated with cortical changes and altered tactile acuity. Tactile acuity is considered a clinical signature of primary somatosensory representation. The two-point discrimination (TPD) threshold is increasingly used both clinically and in research. Remarkably, the reliability and precision of the measure at commonly used sites has not been determined. This study aimed to determine the utility, intra- and inter-rater reliability, bias and variability of TPD threshold assessment at the neck, back, hand and foot using mechanical callipers. ⋯ Individual clinicians are able to reliably assess TPD threshold at the neck, back, hand and foot using mechanical callipers. Measures obtained by different clinicians were only reliable for the neck and foot. Large variability was observed in all assessments, which suggests clinicians should be cautious when interpreting changes in tactile acuity in individual patients.

Treatment changes and improved outcomes in RA: an overview of a large inception cohort from 1989 to 2009.
The introduction of effective treatment strategies in the past two decades has changed the management of RA dramatically. The objective was to analyse the changes in disease activity, function, joint damage and incidence of orthopaedic surgery over a period of 20 years (1989-2009) for patients with RA. ⋯ Treatment strategy changed in a large inception cohort of patients with RA which coincided with decreased disease activity, increased functional ability and fewer orthopaedic interventions since the early 1990s.
