Shoulder MRI features with clinical correlations in subacromial pain syndrome: a cross-sectional and prognostic study
Abstract Background Previous studies on shoulder patients have suggested that the prevalence of rotator cuff or bursa abnormalities are weakly related to symptoms and that similar findings are often found in asymptomatic persons. In addition, it is largely unknown whether structural changes identified by magnetic resonance imaging (MRI) affect outcome after treatment for shoulder pain. The purpose of this study was therefore to evaluate the presence of structural changes on MRI in patients with subacromial pain syndrome and to determine to what extent these changes are associated with symptoms and predict outcome after treatment (evaluated by the Shoulder Pain and Disability Index (SPADI)). Methods A prospective, observational assessment of a subset of shoulder patients who were included in a randomized study was performed. All participants had an MRI of the shoulder. An MRI total score for findings at the AC joint, subacromial bursa and rotator cuff was calculated. Multiple linear regression analysis was applied to examine the relationship between the MRI total score and the outcome measure at baseline and to examine to what extent the MRI total score was associated with the change in the SPADI score from baseline to the one year follow-up. Results There was a weak, inverse association between the SPADI score at baseline and the MRI total score (β = −3.1, with 95% CI −5.9 to −0.34; p = 0.03), i.e. the SPADI score was higher for patients with a lower MRI total score. There was an association between the change in the SPADI score from baseline to the one year follow-up and the MRI total score (β = 8.1, 95% CI -12.3 to −3.8; p < 0.001), with a poorer outcome for patients with a higher MRI total score. Both tendinosis (p = 0.01) and bursitis (p = 0.04) were associated with a poorer outcome after one year. Conclusions In this study, MRI findings were significantly associated with the change in the SPADI score from baseline and to one year follow-up, with a poorer outcome after treatment for the patients with higher MRI total score, tendinosis and bursitis on MRI.

Not only oxidized R-(+)- but also S-(-)-limonene is a common cause of contact allergy in dermatitis patients in Europe
Limonene, one of the most often used fragrance terpenes in any kind of scented products, is prone to air-oxidation. The oxidation products formed have a considerable sensitizing potential. In previous patch test studies on consecutively tested dermatitis patients, oxidized R-limonene has been proven to be a good and frequent indicator of fragrance-related contact allergy. The current study extends these investigations to 6 European clinics of dermatology, where the oxidation mixture of both enantiomers of limonene (R and S) have been tested in 2411 dermatitis patients. Altogether, 63 out of 2411 patients tested (2.6%) reacted to 1 or both the oxidized limonene preparations. Only 2.3% reacted to the oxidized R-limonene and 2.0% to the oxidized S-limonene. In 57% of the cases, simultaneous reactions were observed to both oxidation mixtures. Concomitant reactions to the fragrance mix, colophonium, Myroxylon pereirae, and fragrance-related contact allergy were common in patients reacting to 1 or both the oxidized limonene enantiomers. Our study provides clinical evidence for the importance of oxidation products of limonene in contact allergy. It seems advisable to screen consecutive dermatitis patients with oxidized limonene 3% petrolatum, although this patch test material is not yet commercially available
Reverse shoulder arthroplasty is superior to plate fixation at 2 years for displaced proximal humeral fractures in the elderly: a multicenter randomized controlled trial
Almost one-third of patients with proximal humeral fractures are treated surgically, and the number is increasing. When surgical treatment is chosen, there is sparse evidence on the optimum method. The DelPhi (Delta prosthesis-PHILOS plate) trial is a clinical trial comparing 2 surgical treatments. Our hypothesis was that reverse total shoulder arthroplasty (TSA) yields better clinical results compared with open reduction and internal fixation (ORIF) using an angular stable plate. The DelPhi trial is a randomized controlled trial comparing reverse TSA with ORIF for displaced proximal humeral fractures (OTA/AO types 11-B2 and 11-C2) in elderly patients (65 to 85 years of age). The primary outcome measure was the Constant score at a 2-year follow-up. The secondary outcome measures included the Oxford Shoulder Score and radiographic evaluation. Results were reported as the mean difference with 95% confidence interval (CI). The intention-to-treat principle was applied for crossover patients. There were 124 patients included in the study. At 2 years, the mean Constant score was 68.0 points (95% CI, 63.7 to 72.4 points) for the reverse TSA group compared with 54.6 points (95% CI, 48.5 to 60.7 points) for the ORIF group, resulting in a significant mean difference of 13.4 points (95% CI, 6.2 to 20.6 points; p < 0.001) in favor of reverse TSA. When stratified for fracture classification, the mean score was 69.3 points (95% CI, 63.9 to 74.7 points) for the reverse TSA group and 50.6 points (95% CI, 41.9 to 59.2 points) for the ORIF group for type-C2 fractures, which yielded a significant mean difference of 18.7 points (95% CI, 9.3 to 28.2 points; p < 0.001). In the type-B2 fracture group, the mean score was 66.2 points (95% CI, 58.6 to 73.8 points) for the reverse TSA group and 58.5 points (95% CI, 49.6 to 67.4 points) for the ORIF group, resulting in a nonsignificant mean difference of 7.6 points (95% CI, -3.8 to 19.1 points; p = 0.19). At a 2-year follow-up, the data suggested an advantage of reverse TSA over ORIF in the treatment of displaced OTA/AO type-B2 and C2 proximal humeral fractures in elderly patients
