Randomized Controlled TrialPalpation versus ultrasound-guided corticosteroid injections and short-term effect in the distal radioulnar joint disorder: a randomized, prospective single-blinded study.
The aim of this study was to conduct a randomized, prospective single-blinded clinical study on the mid-term benefits and accuracy rate of the ultrasound (US)-guided versus palpation-guided intra-articular (IA) injections for the treatment of distal radioulnar joint (DRUJ) disorder. Subjects with DRUJ disorder (n = 60) were randomly assigned to undergo US-guided or palpation-guided IA injection. Primary outcomes were measured with Disability of the Arm, Shoulder, and Hand questionnaire (DASH) and secondary outcomes included Verbal Numeric Pain Scale (VNS), Modified Mayo Wrist Score (MMWS), range of motion (ROM), and accuracy rate between two groups; 1.25 mL of mixed material (0.5 ml Omnipaque + 1 % lidocaine 0.25 ml + triamcinolone 20 mg 0.5 ml) was injected into the intra-articular space of the DRUJ. ⋯ VNS, DASH, MMWS, and ROM were improved at 1, 3, and 6 months in both groups. There was no significant difference in clinical outcomes between the group receiving US-guided injections and the group receiving palpation-guided injections. US-guided IA injection showed significantly higher accuracy than palpation-guided IA injection in the DRUJ, and corticosteroid IA injections were effective in improving of the pain of patients with DRUJ disorder during 6 months of follow-up.

Translation into Brazilian Portuguese, cross-cultural adaptation and validation of the Stanford presenteeism scale-6 and work instability scale for ankylosing spondylitis.
Loss of productivity at work, as a result of health problems, is becoming an issue of interest due to the high burden it represents in society. The measurement of such phenomenon can be made using generic and specific scales for certain diseases such as the Stanford Presenteeism Scale (SPS-6) and the Work Instability Scale for Ankylosing Spondylitis (AS-WIS), specific for patients with ankylosing spondylitis (AS). The aim of this study was to translate and perform a cross-cultural adaptation of SPS-6 and AS-WIS into Portuguese and check their psychometric properties. ⋯ The process of translation, cross-cultural adaptation, and validation of the SPS-6 as a generic measurement for the loss of productivity at work and of the AS-WIS as a specific measurement for patients with AS are valid, reproducible, and specific instruments to be used in Brazil. In both scales, productivity at work was associated to advanced age, higher rate of absenteeism in the last month and year, presence of peripheral arthritis, and a larger number of comorbidities in patients with AS. The AS-WIS and SPS-6 showed a good correlation among them although they are not mutually exclusive but supplementary.
