ObjectivesTo evaluate the presence of lymphocyte aggregates in synovial tissue of patients with early arthritis in relationship to clinical outcome and to determine whether this is a stable feature over time.MethodsArthroscopic synovial biopsy samples were collected in a prospective cohort of disease-modifying antirheumatic drug-naïve patients with early arthritis (<1 year's disease duration) at baseline (n=93) and, if rheumatoid arthritis was suspected, after 6 months of follow-up (n=17). After 2 years of follow-up, definitive diagnosis and clinical outcome were assessed. Size of synovial lymphocyte aggregates was graded (score 1–3). Lymphoid neogenesis (LN) was defined by the presence of grade ≥2 aggregates and subclassified based on the presence of follicular dendritic cells (FDCs).ResultsLN was present in 36% of all patients and FDCs in 15% of patients with LN. Presence of lymphocyte aggregates differed over time. LN was associated with the degree of synovial inflammation. There was no relationship between the presence of lymphocyte aggregates at baseline and definitive diagnosis or clinical outcome after follow-up.ConclusionsPresence of lymphocyte aggregates is a dynamic phenomenon related to the degree of synovitis and can be detected in different forms of early arthritis. This feature does not appear to be related to clinical outcome.

Background and Purpose: There is interest in what happens over time to the thrombus after intravenous alteplase. We study the effect of alteplase on thrombus structure and its impact on clinical outcome in patients with acute stroke. Methods: Intravenous alteplase treated stroke patients with intracranial internal carotid artery or middle cerebral artery occlusion identified on baseline computed tomography angiography and with follow-up vascular imaging (computed tomography angiography or first run of angiography before endovascular therapy) were enrolled from INTERRSeCT study (Identifying New Approaches to Optimize Thrombus Characterization for Predicting Early Recanalization and Reperfusion With IV Alteplase and Other Treatments Using Serial CT Angiography). Thrombus movement after intravenous alteplase was classified into complete recanalization, thrombus migration, thrombus fragmentation, and no change. Thrombus migration was diagnosed when occlusion site moved distally and graded according to degrees of thrombus movement (grade 0–3). Thrombus fragmentation was diagnosed when a new distal occlusion in addition to the primary occlusion was identified on follow-up imaging. The association between thrombus movement and clinical outcome was also evaluated. Results: Among 427 patients in this study, thrombus movement was seen in 54% with a median time of 123 minutes from alteplase administration to follow-up imaging, and sub-classified as marked (thrombus migration grade 2–3 + complete recanalization; 27%) and mild to moderate thrombus movement (thrombus fragmentation + thrombus migration grade 0–1; 27%). In patients with proximal M1/internal carotid artery occlusion, marked thrombus movement was associated with a higher rate of good outcome (90-day modified Rankin Scale, 0–2) compared with mild to moderate movement (52% versus 27%; adjusted odds ratio, 5.64 [95% CI, 1.72–20.10]). No difference was seen in outcomes between mild to moderate thrombus movement and no change. In M1 distal/M2 occlusion, marked thrombus movement was associated with improved 90-day good outcome compared with no change (70% versus 56%; adjusted odds ratio, 2.54 [95% CI, 1.21–5.51]). Conclusions: Early thrombus movement is common after intravenous alteplase. Marked thrombus migration leads to good clinical outcomes. Thrombus dynamics over time should be further evaluated in clinical trials of acute reperfusion therapy.

Abstract BACKGROUND: Arteriovenous malformations (AVM) with associated aneurysms (AA) increase the risk of hemorrhage in adults. Associated aneurysms are thought to develop over time, and the incidence in children, therefore, has been thought to be minimal, although this has not yet been studied. OBJECTIVE: To define the incidence and morbidity of AA in children and to assess the results of our treatment strategy. METHODS: Patients younger than 18 years of age with pial AVM seen from 2000 to 2009 were reviewed. Demographics, presentation, hemorrhage, AAs, treatment method, and outcome were analyzed. RESULTS: Of 144 patients with AVM, 30 were younger than 18 years of age. AA was identified in 5 of 30 children (16.7%) and 33 of 114 adults (28.9%; P = .25). Mean age at presentation in children was 11.67 years (range, 6 months to 17 years), and mean follow-up was 28.8 months (range, 1-75 months). Hemorrhage at presentation was seen in 80% of patients with AA and 72% with AVM alone. Emergent therapy was required in 60% of patients with AA and 40% with AVM alone (P = .63). Time to treatment was 4.3 days with AA and 27.3 days without (P = .42). There was no difference in outcome between patients with AA and those with AVM alone. CONCLUSION: The incidence of pediatric AA was higher in our series than projected in the current literature. Time to treatment was shorter in children with AA compared with those with AVM alone, although there was no difference in clinical outcome. Although hemorrhage rates were similar, emergent therapy was required more often in patients with AA. Our findings support the need for early diagnosis and treatment of associated aneurysms in children.

Background: Cell-free devices have been introduced to restore osteochondral defects, avoiding the limitations of cell-based procedures. Among these, an osteochondral scaffold made of type I collagen and hydroxyapatite has been investigated with promising results up to medium-term follow-up. However, the clinical and imaging results over time still need to be documented. Purpose: To evaluate the clinical outcome and tissue maturation at long-term follow-up after the implantation of the osteochondral scaffold. Study Design: Case series; Level of evidence, 4. Methods: A total of 24 patients (7 women, 17 men; age, 36 ± 9.5 years) underwent surgical implantation of the osteochondral scaffold and were prospectively evaluated before surgery, at 2-, 5-, and 10-year follow-up. The mean defect size was 2.9 ± 1.4 cm2. Patients were evaluated using the International Knee Documentation Committee (IKDC) subjective and objective scores, and the activity level was documented with the Tegner score. Magnetic resonance imaging (MRI) evaluation involved the use of the magnetic resonance observation of cartilage repair tissue score combined with 5 more variables focused on the bone layer. Results: A statistically significant improvement of all clinical scores was documented from the baseline to the final evaluation. The IKDC subjective score improved from the preoperative level to 2 years (41 ± 13.2 and 77.1 ± 14.6, respectively) ( P < .0005), with stable results up to 10 years (77.4 ± 19.4). The IKDC objective score changed from 52% of normal and nearly normal knees before the treatment to 84% at 10 years ( P < .0005). Tegner sports activity at the final evaluation (3.8 ± 1.7) was higher compared with the preoperative level (1.6 ± 1.1; P < .05), but it remained significantly lower compared with the preinjury level (5.5 ± 2.6; P < .05). Treatment failed in 1 patient. Persisting graft alterations were observed on MRI scans, although without correlating with the clinical outcome. Conclusion: The regenerative potential of this scaffold is limited, as demonstrated by the signal alterations persisting over time on MRI scans. On the other hand, the clinical improvement was significant and stable over time both in terms of subjective and objective outcomes, including activity level, with overall good results.

Background:EULAR guidelines stress timely initiation of DMARD-treatment in early arthritis patients also when classification criteria are not yet fulfilled. Consequently, undifferentiated arthritis (UA) patients may be increasingly treated with disease modifying antirheumatic drugs (DMARDs), despite inadequate placebo-controlled evidence for its effectivity. Implementation of this guideline also hampers future placebo-controlled trials in UA. However, historical data, with inclusion period as instrumental variable, can provide insight whether long term outcome is improved with increased DMARD-use, and thus serve to investigate if DMARD-treatment is effective in UA.Objectives:With 25-years of observational data of newly referred UA-patients, we studied whether enhanced treatment strategies resulted in better long term outcomes for UA.Methods:Between 1993 and 2019, 1132 consecutive UA-patients, not fulfilling the 1987/2010 criteria for RA or any other distinct diagnosis, were included in the Leiden Early Arthritis Cohort; patients were divided in 5 inclusion periods (1993-1998, 1999-2005, 2006-2010, 2011-2014, 2015-2019). Frequency of DMARD-initiation after diagnosis was compared. We studied the following outcomes: the course of disease activity scores (DAS28-CRP) and Health assessment questionnaires (HAQ), progression to RA after 1-year (according to the 1987 and/or 2010 criteria) and the frequency of prolonged DMARD-free status within 10-years of follow-up (this was defined as either spontaneous remission or sustained remission after discontinuation of DMARD-treatment).Results:The current population of UA-patients, thus not fulfilling 1987 or 2010 criteria, had rather mild disease: the median SJC was 1, the median TJC 2, 95% was autoantibody-negative and the median HAQ was 0.6. These characteristics were similar in the different inclusion periods. Initiation of DMARD-treatment in UA increased over time: 18%, 35%, 38%, 43% up to 55% in respectively 1993-1998, 1999-2005, 2006-2010, 2011-2014 and 2015-2019, in which methotrexate became more common in the last decade. Frequency of progression to RA after 1-year did not decrease and was 14%, 21%, 26%, 19% and 28% in the respective inclusion periods. Long-term DAS28CRP-scores improved from 2011 onwards (range -0.18, -0.24; p<0.05). However HAQ-score over time did not improve compared to the 1993-1998 period (range -0.00, -0.08; p>0.05). Also the percentages of patients in DMARD-free status after 10-years of follow-up did not significantly improve over time: 57%, 58%, 59% (for 1993-1998, 1999-2005, 2006-2010 respectively, p=0.59).Conclusion:Intensified DMARD-treatment of patients with UA did not result in improved outcomes. These data may indicate overtreatment of UA-patients. Yet, methods to stratify which UA-patients should be treated remains warranted.Disclosure of Interests:None declared

Purpose To evaluate whether there is a change in findings of coronavirus disease 2019 patients in follow up lung ultrasound and to determine whether these findings can predict the development of severe disease. Materials and methods In this prospective monocentric study COVID-19 patients had standardized lung ultrasound (12 area evaluation) at day 1, 3 and 5. The primary end point was detection of pathologies and their change over time. The secondary end point was relationship between change in sonographic results and clinical outcome. Clinical outcome was assessed on development of severe disease defined as need for intensive care unit. Results Data of 30 patients were analyzed, 26 patients with follow-up lung ultrasound. All of them showed lung pathologies with dynamic patterns. 26,7% developed severe disease tending to have an ubiquitous lung involvement in lung ultrasound. In patients with need for intensive care unit a previously developed increase in B-lines, subpleural consolidations and pleural line irregularities was more common. A statistically significant association between change in B-lines as well as change in pleural line irregularities and development of severe disease was observed (p<0,01). Conclusion The present study demonstrates that follow up lung ultrasound can be a powerful tool to track the evolution of disease and suggests that lung ultrasound is able to indicate an impending development of severe disease in COVID-19 patients.

Objectives: Despite various treatment options, the successful management of irreparable, massive rotator cuff tears (MRCTs) remains challenging. Implantation of a biodegradable subacromial balloon spacer (InSpaceTM system; OrthoSpace, Caesarea, Isreal) has gained considerable interest for the treatment of MCRTs due to its ability to effectively recenter the humeral head within the glenoid. Despite promising results, investigations examining outcomes following balloon spacer implantation are limited to small case series and short-term prospective trials without comparison to other surgical modalities. The purpose of the present investigation was to prospectively evaluate the safety and efficacy of the arthroscopically deployed, subacromial spacer balloon compared to partial rotator cuff repair in patients with MRCTs at 24 month follow up. Methods: A non-inferiority, prospective, single-blinded, multicenter, randomized, controlled, pivotal study was conducted to compare the outcomes of arthroscopic subacromial balloon spacer implantation to partial repair in the treatment of MRCTs. Patients ≥ 40 years of age with symptomatic full thickness MRCTs (tears ≥ 5 cm or ≥ 2 tendons) that had failed non-operative management were included. Clinical outcome data, derived from subjective questionnaires and physical examination, were collected at baseline and follow-up intervals at Day 10, Week 6, Month 3, 6, 12 and 24. Postoperative magnetic resonance imaging (MRI) scans were obtained at 6 weeks and 12 months. The primary composite effectiveness endpoint was defined as achievement of the minimal clinically important difference (MCID) for the Western Ontario Rotator Cuff (WORC) score (275 points) and American Shoulder and Elbow Society (ASES) score (6.4 points) by week 6 and maintenance at month 12 without subsequent secondary surgical intervention (SSSI) or serious adverse device effects (SADEs). Secondary effectiveness endpoints included changes in individual and composite clinical outcome scores relative to baseline in addition to MRI findings. Intention-to-treat (ITT), per-protocol (PP), and safety analyses were performed separately. Results: A total of 20 sites were enrolled in the investigation. One hundred, eighty-four patients were randomized into the clinical study (n= 93 balloon spacer; n= 91 partial repair) and included in the safety population, of which 183 patients were included in the ITT analysis (n=93 balloon spacer; n= 90 partial repair) and 176 in the PP analysis (n= 88 balloon spacer; n= 88 partial repair). No significant difference in demographic characteristics based on mean age, sex, race or body mass index were appreciated between groups. Mean procedure duration was 44.6 ± 16.9 minutes for the balloon spacer group and 71.2 ± 30.1 minutes for the partial repair group. Significant improvement over time relative to baseline was observed in all WORC (Fig. 1) and ASES (Fig. 2) scores in both groups. The magnitude of improvement for subjects in the balloon spacer group was the same or better than for subjects in the partial repair group at 12 and 24 month follow up. At 12 months, 51% (n=45 of 88) of patients in the balloon spacer group and 35 patients 40% (n= 35 of 88) in the partial repair group had reached and maintained the primary composite endpoint, meeting the noninferiority criteria (non-inferiority margin 10%; p = 0.0049) and corresponding to an 11.4% mean advantage for the spacer implant group. Non-inferiority was similarly confirmed in the ITT population (p=0.0089). SSSI occurred in 6 subjects (n=3 balloon spacer; n=3 partial repair), with two subjects in each group requiring reverse shoulder arthroplasty and one subject in each group undergoing shoulder arthroscopy. Conclusions: Use of the balloon spacer was found to produce non-inferior outcomes when compared to partial rotator cuff repair for patients with MRCTs at 24 month follow up. Outcomes following balloon spacer device placement met non-inferiority criteria when compared to the partial repair group based on primary composite endpoints.

AbstractThis study aimed to evaluate whether manipulation under anesthesia (MUA) affect clinical outcome including range of motion (ROM) and patient satisfaction after total knee arthroplasty (TKA). It is hypothesized that MUA improves clinical outcomes and patient satisfaction after primary TKA. This retrospective study analyzed 97 patients who underwent staged bilateral primary TKA. MUA of knee flexion more than 120 degrees was performed a week after index surgery just before operation of the opposite site. The first knees with MUA were classified as the MUA group and the second knees without MUA as the control group. ROM, Knee Society Knee Score, Knee Society Functional Score, Western Ontario and McMaster Universities (WOMAC) score, and patient satisfaction were assessed. Postoperative flexion was significantly greater in the MUA group during 6 months follow-up (6 weeks: 111.6 vs. 99.8 degrees, p < 0.001; 3 months: 115.9 vs. 110.2 degrees, p = 0.001; 6 months: 120.2 vs. 117.0 degrees, p = 0.019). Clinical outcomes also showed similar results with knee flexion during 2 years follow-up. Patient satisfaction was significantly high in the MUA group during 12 months (3 months: 80.2 vs. 71.5, p < 0.001; 6 months: 85.8 vs. 79.8, p < 0.001; 12 months: 86.1 vs. 83.9, p < 0.001; 24 months: 86.6 vs. 85.5, p = 0.013). MUA yielded improvement of clinical outcomes including ROM, and patient satisfaction, especially in the early period after TKA. MUA in the first knee could be taken into account to obtain early recovery and to improve patient satisfaction in staged bilateral TKA.
