Giant cell tumors of the synovial tendon sheaths (GCTSTS) are a localized form of hemopigmented villonodular synovitis. They mainly affect the hands. This study aims to analyse the epidemiology, clinical and therapeutic characteristics of GCTSTS, to assess the results of surgical treatment and to identify risk factors for recurrences. We conducted a retrospective data collection from medical records of 50 patients with GCTSTS of the hand between 1992 and 2016 in the Department of Orthopaedics at the Hospital of Sahloul (Sousse-Tunisia)...

In this study, we found that catechins found in green tea (EGCG, EGC, and EC) differentially interfere with the IL-1β signaling pathway which regulates the expression of pro-inflammatory mediators (IL-6 and IL-8) and Cox-2 in primary human rheumatoid arthritis synovial fibroblasts (RASFs). EGCG and EGC inhibited IL-6, IL-8, and MMP-2 production and selectively inhibited Cox-2 expression. EC did not exhibit any inhibitory effects. When we looked at the expression of key signaling proteins in the IL-1β signaling pathway, we found all the tested catechins could inhibit TAK-1 activity...

BACKGROUND: Injuries penetrating synovial structures are common in equine practice and often result in septic synovitis. Significantly increased plasma levels of serum amyloid A (SAA) have been found in various infectious conditions in horses including wounds and septic arthritis. Plasma SAA levels were found to decrease rapidly once the infectious stimulus was eliminated. The purpose of the current study was to investigate the usefulness of serial measurements of plasma SAA as a monitoring tool for the response to treatment of horses presented with injuries penetrating synovial structures...

Synovial sarcoma is clinically rare, and cases of synovial sarcoma arising in the omentum are particularly rare. Only 3 cases have been reported in the literature to dtae, and they were associated with a poor prognosis. We herein report a rare case of aggressive primary omental synovial sarcoma presenting as an ovarian malignancy. A 53-year-old multigravida woman was referred to our hospital due to progressive abdominal distension. Magnetic resonance imaging revealed a large heterogeneous mass with an irregular component occupying the lower abdominal cavity, with an intact uterus...

Surface-active phospholipid (SAPL) secreted in the synovial joint plays an important role in cartilage integrity. In healthy joints, phospholipid multibilayers coat the cartilage surface, providing boundary lamellar-repulsive hydration lubrication. Current mechanism for lubrication of synovial joints, as well as the physical and chemical nature of the cartilage surface is discussed. Friction between phospholipid (PL) bilayers attached to cartilage surfaces is considered including a discussion on the recent observation of an extreme friction reduction as a consequence of a less charged hydrophilic cartilage surface...

Adventitial cystic disease is an uncommon condition that is characterized by the collection of mucinous material that accumulates in the adventitial layer of the artery. Predominantly, this entity affects the popliteal artery, whereas it is extremely rare in the radial artery. We report a 72-year-old female patient that underwent surgical treatment of an adventitial cyst of the right radial artery. The involved arterial segment was resected, and reconstruction by means of the interposition of a saphenous vein graft was performed...

Pseudogout is a form of acute calcium pyrophosphate deposition (CPPD) disease that typically afflicts the elderly. CPPD commonly involves larger joints, such as the knees, wrists, shoulders, and hips, and has been known to involve the spine. The authors report the case of a 66-year-old woman with a recent history of lumbar laminectomy and fusion who presented 5 weeks postprocedure with a clinical and radiographic picture consistent with multilevel skip lesions involving the cervical and thoracic spine, thoracic discitis, and epidural abscess...

OBJECTIVE: Prospectively monitor how treatment of acutely ruptured anterior cruciate ligament (ACL) affects biomarkers of inflammation and proteolytic degradation over five years. DESIGN: We studied 119 subjects with acute ACL injury from the randomized controlled KANON-trial (Clinical trial ISRCTN 84752559) who had synovial fluid, serum and urine samples available from at least two out of six visits over five years after acute ACL rupture. All subjects followed a similar rehabilitation protocol where, according to randomization, 60 also had early ACL reconstruction and 59 had the option to undergo a delayed ACL reconstruction if needed...

Deregulation of MYC oncoprotein in cancers can result from multiple oncogenic mechanisms. Although MYC translocations define Burkitt lymphoma and MYC protein expression is a poor prognostic factor in undifferentiated neuroblastomas, the distribution of MYC protein (c-MYC) across other pediatric small round blue cell tumors (SRBCT) has not been well characterized. We undertook this study to assess MYC protein expression in a large cohort of pediatric lymphomas, sarcomas, and other SRBCT. Tissue microarrays containing 302 SRBCT were successfully evaluated by immunohistochemistry using anti-MYC clone Y69, with nuclear positivity scored as 0%, 1%-25%, 26%-50%, 51%-75%, or 76%-100%...

REVIEW
Taha Rashid, Alan Ebringer, Clyde Wilson
Rheumatoid arthritis (RA) is a relatively common and potentially disabling immune-mediated inflammatory systemic disease, predominantly affecting women and characterised by multiple small joint arthritis. Extensive data supports the roles of genetic, environmental and microbial factors in the triggering and development of this disease. Proteus mirabilis is considered as the main microbial culprit in the causation of RA. The evidence for the role of these microbes in RA and their links with commonly associated autoantibodies such as rheumatoid factors and anti-citrullinated peptide antibodies have been elucidated together with their relations with some of the non-microbial environmental factors which have been implicated in the aetiopathogenesis of RA...

REVIEW
Frances Claire Humby, Farida Al Balushi, Gloria Lliso, Alberto Cauli, Costantino Pitzalis
Although great progress has been made in the past decade toward understanding the pathogenesis of rheumatoid arthritis (RA), clinicians remain some distance from a goal of personalized health care. The capacity to diagnose RA early, predict prognosis, and moreover predict response to biologic therapies has been a research focus for many years. How currently available clinical prediction models can facilitate such goals is reviewed in this article. In addition, the role of current imaging techniques in this regard is also discussed...
