Abstract
OBJECTIVE Evidence points to a decreased breast cancer risk in systemic lupus erythematosus (SLE). We analyzed data from a large multisite SLE cohort, linked to cancer registries. METHODS Information on age, SLE duration, cancer date, and histology was available. We analyzed information on histological type and performed multivariate logistic regression analyses of histological types according to age, SLE duration, and calendar year. RESULTS We studied 180 breast cancers in the SLE cohort. Of the 155 cases with histology information, 11 were referred to simply as 'carcinoma not otherwise specified'. In the remaining 144 breast cancers, the most common histological type was ductal carcinoma (n = 95; 66%) followed by lobular adenocarcinoma (n = 11; 8%), 15 cancers were of mixed histology, and the remaining ones were special types. In our regression analyses, the independent risk factors for lobular versus ductal carcinoma was age [odds ratio (OR) 1.07, 95% confidence interval (CI) 1.01-1.14] and for the 'special' subtypes it was age (OR 1.06, 95% CI 1.01-1.10) and SLE duration (OR 1.05, 95% CI 1.00-1.11). CONCLUSIONS Generally, up to 80% of breast cancers are ductal carcinomas. Though our results are not definitive, in the breast cancers that occur in SLE, there may be a slight decrease in the ductal histological type. In our analyses, age and SLE duration were independent predictors of histological status.

Abstract
Integrin very late antigen-4 (VLA4) is induced during inflammation and can regulate monocyte migration. It has been implicated in atherogenesis, a significant concern in systemic lupus erythematosus (SLE). The aim of this study was to define VLA4 expression in SLE monocytes. Flow cytometry, reverse transcription polymerase chain reaction, Western blotting, and immunohistochemistry staining with confocal microscopy were used to evaluate VLA4 expression in SLE patients and controls. We found elevated expression of VLA4 in SLE patients with significantly increased VLA4 staining intracellularly compared to control. Exposure of control monocytes to SLE sera or immune complexes led to increased intracellular expression, and immune complexes were capable of driving redistribution of surface VLA4 to the cytoplasm. Therefore, VLA4 was found to be subject to complex regulation with SLE sera driving both RNA expression and redistribution of protein. Stimulation of SLE monocytes with a VLA4 ligand induced significant TNFα expression, confirming a functional effect. This behavior may contribute to increased atherosclerosis and monocyte infiltrates in end organs.

Abstract
Intermediate-energy Coulomb excitation measurements are performed on the N ≥ 40 neutron-rich nuclei (66,68)Fe and (64)Cr. The reduced transition matrix elements providing a direct measure of the quadrupole collectivity B(E2;2(1)(+) → 0(1)(+)) are determined for the first time in (68)Fe(42) and (64)Cr(40) and confirm a previous recoil distance method lifetime measurement in (66)Fe(40). The results are compared to state-of-the-art large-scale shell-model calculations within the full fpgd neutron orbital model space using the Lenzi-Nowacki-Poves-Sieja effective interaction and confirm the results of the calculations that show these nuclei are well deformed.

Abstract
OBJECTIVE Our aim was to assess whether erythrocyte sedimentation rate (ESR) levels correlate with the level of disease activity at each visit and whether a change in ESR could be useful in predicting changes in disease activity. METHODS Thousands of visits in a prospective systemic lupus erythematosus (SLE) cohort were analyzed to assess the association of ESR and level of disease activity. We explored whether ESR was cross-sectionally associated with disease activity, whether changes in ESR were associated with changes in disease activity, and whether changes in ESR predicted future changes in disease activity. Visits when patients had cancer, infection, pregnancy or were in renal failure were excluded. RESULTS After adjusting for confounding factors, mild (25-50 mm/h), moderate (51-75 mm/h), and marked (>75 mm/h) elevations in ESR levels at a given visit correlated with the SELENA-SLEDAI, the Physician Global Assessment (PGA), fatigue, renal, joint, rash, serositis, hematological visual analogue scale (VAS), hematuria and proteinuria (p<0.0001) levels at that visit. A change in ESR between two visits was highly correlated with a concurrent change in PGA, renal, fatigue and joint VAS (p<0.0001). There was no statistically significant correlation between change in ESR between two visits and change in disease activity at a future visit. The subgroup analysis of patients who do not have anti-dsDNA and low complement levels as a feature of their disease showed ESR to be positively associated with SLEDAI, PGA, renal and joint VAS at that visit (p<0.0001), but there were few significant associations between changes in ESR and changes in disease activity. CONCLUSION ESR is associated with disease activity in SLE measured by the SELENA-SLEDAI, the PGA, and with organ-specific activity including serositis, rash, joint, renal and hematological VAS. Grouping baseline ESR into four levels does associate with both global and organ-specific disease activity. A change in ESR between two visits was highly correlated with a change in PGA, renal, fatigue and joint VAS. In patients without anti-dsDNA and low complement levels, ESR was positively associated with SLEDAI, PGA, renal and joint VAS at the same visit. Until more specific biomarkers are validated, serial ESR does have some utility in following disease activity in SLE.

Abstract
Purpose Organ damage in systemic lupus erythematosus (SLE) patients is highly associated with the use of corticosteroids. Doses of prednisone below 6 mg daily are associated with reduced organ damage. We now report on the largest prospective cohort study of predictors of prednisone tapering in SLE patients. Methods A total of 866 SLE patients (91% female, 50% Caucasian, 43% African-American, mean age 43 years) who consented for the Hopkins Lupus Cohort from 1987 through 2009 were included. The analysis was based on patient visits in which the previously prescribed dose of prednisone was 5 mg/day. We then examined the proportion of times the patient’s dose was reduced to below 5 mg/day (“tapering”). Among those patients who tapered and were followed for at least one year thereafter, we examined the proportion whose prednisone dose remained below 5 mg/day for at least one year (“Successful tapering”). Rates of tapering and successful tapering were calculated for patient subsets based on demographic and clinical characteristics. Result The analyses showed that Caucasians, younger patients, patients with a higher level of education, lower disease activity, or absence of urine protein were more likely to have a prednisone taper. However, successful tapering was not dependent on age, ethnicity, or education. As expected, successful tapering was more frequent in those with lower disease activity. Successful tapering was achieved more often after the year 2000. Conclusion Our study suggests that successful tapering of prednisone below 5 mg has increased since the year 2000, which may reflect the greater knowledge of the long-term harm of even low-dose chronic corticosteroid use. Caucasians, younger age, higher level of education, and absence of proteinuria predicted tapering, but not successful tapering. Ongoing cutaneous or arthritis activity were associated with unsuccessful tapering. Lack of disease activity, as expected, was the only major clinical variable that significantly predicted successful tapering.

Abstract
Complex ligament injuries can compromise a knee joint and residual conditions comprise stiffness (arthrofibrosis), instability, cartilage damage leading to osteoarthritis and bone deformity. Accurate diagnosis must address the direction and extent of the instability, the severity of any cartilage lesion and an analysis of the axis and bone deformity as well as important cofactors. Therapeutic options are adhesiolysis, ligament reconstruction, cartilage regeneration and axis correction. As a consequence patients mostly profit from the procedure but there is never a return to the functional level that existed before injury.

Abstract
We report the 18-year follow-up of a patient who underwent rotationplasty for severe bone loss and infection after an grade IIIC open fracture of the distal femur. The patient is now 49 years old and fully satisfied with his life. During the follow-up period, he has never had significant physical or psychological problems directly concerning the rotationplasty. The analysis of quality of life using the SF36 questionnaire revealed even higher scores than the normal healthy population in seven out of eight sub-categories. Clinical examination revealed bland soft tissues without hyperkeratosis or other signs of maladaptation. Articular and cutaneous proprioception was intact all over the left leg. The active extension/flexion of the prosthetic knee was 0°-0°-100° and 10°-0°-70° of the ankle joint. Manual testing of motor strength revealed grade five of five for dorsiflexion and plantar flexion of the ankle. Gait patterns including climbing slopes and stairs were close to normal. Examination in sports physiology showed lower maximum power of hip and knee muscles compared to the healthy side, but better muscular endurance. These findings emphasize that rotationplasty can be a good alternative to arthrodesis or amputation in trauma patients providing high satisfaction and activity levels in the long-term follow-up.

Abstract
PURPOSE Patellar dislocation usually occurs to the lateral side, leading to ruptures of the medial patellofemoral ligament (MPFL) in about 90 % of all cases. Reliable prognostic factors for the stability of the patellofemoral joint after MPFL surgery and satisfaction of the patient have not been established as yet. METHODS This multicentric study retrospectively included 40 patients with a mean age of 22.4 ± 8.1 years (range 9-48) from 5 German Trauma Departments with first-time traumatic patellar dislocation and operative treatment. Surgery was limited to soft tissue repairs, and a preoperative magnetic resonance imaging (MRI) was performed in all cases. Evaluation of the MRI included sulcus angle, dysplasia of the trochlea, depth and facet asymmetry of the trochlea, Insall-Salvati index, Tibial tuberosity to trochlear groove (TTTG) distance, and rupture patterns of the MPFL. Patients were interrogated after 2 years about recurrent dislocation, satisfaction, and the Kujala score. RESULTS Trochlea facet asymmetry was significantly lower in patients with redislocation (23.5 ± 18.8) than in patients without redislocation (43.1 ± 16.5, p = 0.03). Patients with a patellar-based rupture were significantly younger (19.5 ± 7.2 years) than patients without patellar-based rupture (25.4 ± 8.1 years, p < 0.02). Patients with femoral-based ruptures were significantly older (25.7 ± 9.2 years) than patients without femoral-based rupture (19.7 ± 6.1 years, p < 0.02), and had a significantly higher TTTG distance (10.2 ± 6.9 vs. 4.5 ± 5.5, p < 0.02). Patients with incomplete ruptures of the MPFL had a significantly lower Insall-Salvati index (1.2 ± 0.2 vs. 1.4 ± 0.2, p = 0.05). The Kujala score in patients with redislocations was significantly lower (81.0 ± 10.5 points) than in patients without redislocation (91.9 ± 9.2 points, p < 0.02). CONCLUSION Younger patients more often sustain patellar-based ruptures following first-time traumatic patella dislocation, while older patients more often sustain femoral-based ruptures of the MPFL. Incomplete MPFL ruptures are correlated with lower Insall-Salvati indices. Low trochlear facet asymmetry is correlated with higher rates of redislocation. These results may be of relevance for the operative and postoperative treatment in the future. LEVEL OF EVIDENCE Prognostic study, Level IV.

Abstract
INTRODUCTION Patellar dislocation is a common knee injury with mainly lateral dislocations, leading to ruptures of the medial patellofemoral ligament in most of the cases. Even though several prognostic factors for patellofemoral instability have been identified so far, the appropriate therapy for patients with patellar dislocation remains a controversial issue. The purpose of this study was to compare the outcome after conservative or operative treatment in patients after first-time patellar dislocation. PATIENTS AND METHODS This randomized controlled clinical trial was designed multicentric including patients from six German orthopaedic and trauma departments. Twenty patients with a mean age of 24.6 years with first-time traumatic patella dislocation were included and randomized into either a conservative arm or an operative arm. Plain X-ray images of the knee joint (a.p. and lateral view and tangential view of both patellae) were performed in all cases prior to therapy to exclude osteochondral fragments requiring refixation. An MRI was recommended, but not compulsory. Patients were consulted after 6, 12, and 24 months with a questionnaire including the criteria of the Kujala score, recurrent dislocation, and satisfaction. RESULTS The mean Kujala score of the conservative vs operative treatment group was 78.6 vs 80.3 after 6 months (p = 0.842), 79.9 vs 88.9 after 12 months (p = 0.165), and 81.3 vs 87.5 after 24 months (p = 0.339). Redislocation rate after 24 months was 37.5 % in the conservative group and 16.7 % in the operative group (p = 0.347). Due to the small number of patients that could be included, no significant difference between the groups could be detected. We see a tendency towards better results after operative treatment. CONCLUSION Our multicentric prospective randomized controlled trial revealed no significant difference between conservative and operative treatment for patients after first-time traumatic patellar dislocation. However, a tendency towards a better Kujala score and lower redislocation rates for patients with operative treatment was observed. The small number of patients is a limiting factor of the study, leading to results without statistical significance. A meta-analysis including other study's level I data is desirable for the future.

Abstract
Safety data were pooled and analyzed from one phase 2 and two phase 3 double-blind, placebo-controlled, repeat-dose systemic lupus erythematosus (SLE) trials of belimumab 1, 4 (phase 2 only), and 10 mg/kg. Types and rates of adverse events (AEs) were similar across treatment groups. Rates of patients experiencing any serious AE were 16.6%, 19.5%, 13.5%, and 18.0% with placebo, and belimumab 1, 4, and 10 mg/kg, respectively; rates of serious infusion reactions (including hypersensitivity reactions) occurring on the same days as infusions were 0.4%, 0.9%, 0%, and 0.9%, and rates of serious infections were 5.5%, 7.1%, 6.3%, and 5.3%. Malignancy rates/100 patient-years (excluding non-melanoma skin cancer) were 0.29 with placebo vs. 0.20 with all belimumab doses combined; mortality rates/100 patient-years were 0.43 vs. 0.73. These data support the conclusion that belimumab in combination with standard SLE therapy was generally well tolerated in a predominantly autoantibody-positive population with active SLE.
