RATIONALE: (18) F-FDG-PET/CT has a potential role in the early detection of haemophilic arthritis, at a time when treatment may still avoid further joint degeneration. The purposes of this pilot study were to determine the ability of (18) F-FDG-PET/CT to detect inflammatory changes associated with blood-induced arthropathy in knees of a rabbit model. METHODS: Ten juvenile rabbits were imaged at baseline and weeks 5 and 17 post intraarticular autologous blood injections (ABI)...

BACKGROUND: Intra-articular injection of tranexamic acid (TXA) is known to be effective in controlling blood loss after total knee arthroplasty (TKA). However, this method has some disadvantages, such as TXA leakage due to soft tissue release. Peri-articular injection provides an alternative to intra-articular administration of TXA. This study aimed to evaluate the effects of peri-articular injection of TXA in reducing blood loss after TKA and compare them to those of intra-articular TXA injection...

BACKGROUND: Aseptic loosening is a significant impediment to joint implant longevity. Prosthetic wear particles are postulated to play a central role in the onset and progression of periprosthetic osteolysis, leading to aseptic loosening of the prosthesis. METHODS: We investigated the inhibitory effects of a lentivirus-mediated short hairpin RNA that targets the TNF-alpha gene on the particle-induced inflammatory and osteolytic changes via macrophages both in vitro and in vivo...

Dupuytren disease is highly prevalent and the finger contractures can be very extensile, compromising the patients' hand function. To restore full function, contractures have been addressed by cutting the causative strands for nearly 200 years, ever since Baron Guillaume Dupuytren demonstrated his technique at the beginning of the nineteenth century. Surgery can be minimal (fasciotomy) or quite invasive (fasciectomy and even skin replacement). However, in the last decade translational research has introduced the non-surgical technique of enzymatic fasciotomy with collagenase injections...

Orofacial pain conditions including temporomandibular joint disorder and migraine are characterized by peripheral and central sensitization of trigeminal nociceptive neurons. Although calcitonin gene-related peptide (CGRP) is implicated in the development of central sensitization, the pathway by which elevated spinal cord CGRP levels promote peripheral sensitization of primary trigeminal nociceptive neurons is not well understood. The goal of this study was to investigate the role of CGRP in promoting bidirectional signaling within the trigeminal system to mediate sensitization of primary trigeminal ganglion nociceptive neurons...

Chronic pelvic pain in women is a very annoying condition that is responsible for substantial suffering and medical expense. But dealing with this pain can be tough, because there are numerous possible causes for the pelvic pain such as urologic, gynecologic, gastrointestinal, neurologic, or musculoskeletal problems. Of these, musculoskeletal problem may be a primary cause of chronic pelvic pain in patients with a preceding trauma to the low back, pelvis, or lower extremities. Here, we report the case of a 54-year-old female patient with severe chronic pelvic pain after a transcutaneous electrical nerve stimulation (TENS) accident that was successfully managed with image-guided trigger point injections on several pelvic stabilizing muscles...

CCN family protein 2/connective tissue growth factor (CCN2/CTGF) is a unique growth factor that promotes the proliferation and differentiation, but not the hypertrophy of articular chondrocytes in vitro. Based on these findings, we previously evaluated the cartilage-regenerative effects of recombinant CCN2 protein (rCCN2) by using both mono-iodoacetate (MIA) injection into the rat joint cavity and formation of full-thickness defects of rat articular cartilage in vivo, and our results suggested the utility of CCN2 in the regeneration of articular cartilage...

OBJECTIVES: OnabotulinumtoxinA (onabotA) attenuates peripheral nociceptive transduction and consequently neuronal firing. The aim of this mechanistic study was to evaluate the effect of intra-articular (IA) onabotA in patients with painful knee osteoarthritis (OA). METHOD: We conducted a double-blind, randomized, placebo-controlled, 12-week trial using a single ultrasound-guided IA injection of onabotA (200 U). Patients (N = 121) were randomized to receive onabotA (n = 61) or placebo (n = 60)...

Rheumatoid arthritis (RA) and Crohn's disease (CD) are autoimmune disorders with a crosstalk between their pathogenesis such as increased expression of TNF in the target organs. Despite a successful clinical trial with an oral Smad7 antisense oligonucleotide in CD, intraarticular (i.a.) modulation of Smad7 expression has not been performed in rheumatoid joint yet. In this study, contradictory to the findings in CD mucosa, higher levels of pSmad2/3 were found in RA synovium. In vitro experiments with synovial fibroblasts revealed that higher acetylated Smad7 expression was associated with lower activation status...

Systemic lupus erythematosus (SLE), with a high incidence rate and insufficient therapy worldwide, is a complex disease involving multiple organs characterized primarily by inflammation due to deposition of immunocomplexes formed by production of autoantibodies. The mechanism of SLE remains unclear, and the disease still cannot be cured. We used pristane to induce SLE in female BALB/c mice. Methyl salicylate 2-O-β-d-lactoside (MSL; 200, 400, and 800 mg/kg) was orally administered 45 days after pristane injection for 4...

AIMS: Rheumatoid arthritis brings great burdens to the patients. In addition to the highly expensive treatment, they are commonly associated with severe side-effects. In such context, the research for safe and affordable treatments is needed. MAIN METHODS: Arthritis was induced by CFA (0.5mg/mL) in female wistar rats. Trypsin was given p.o. (2.95mg/kg; 2mL) 24 hs after the intra-articular CFA injection. Articular incapacitation was measured daily by counting the paw elevation time (PET; s) during 1-min periods of stimulated walk, throughout the 7-days after intra-articular CFA injection...

Rhein is an active metabolite of the drug diacerein, whose anti-inflammatory properties have been demonstrated in both in vitro and in vivo models. However, the low oral bioavailability of rhein has limited its utility as a potential treatment of osteoarthritis (OA), a chronic inflammatory disease. In order to overcome this limitation, the aim of this work was the development of a drug delivery system intended for intra-articular administration of rhein, based on polymeric biodegradable PLGA microparticles (MPs) loaded with the drug...

BACKGROUND: Internal derangement of the temporomandibular joint (TMJ) is one of the most common forms of temporomandibular disorders. The minimally invasive treatments such as arthrocentesis as well as arthroscopic lysis and lavage are often used as a first-line surgical treatment or in conjunction with nonsurgical modalities with low morbidity and high efficacy. Sodium hyaluronate (SH) has been proposed as an alternative therapeutic agent with similar therapeutic effects. OBJECTIVE: A prospective study was carried out for evaluation of efficacy of TMJ arthrocentesis with and without injection of SH in management of internal derangements...

Osteoarthritis (OA) is a progressive degenerative joint disease and to date, no disease modifying osteoarthritis drug exist. Amniotic membrane and umbilical cord products have been used clinically in several diseases due to their anti-inflammatory and anti-scarring properties. In the present study, we sought to evaluate whether a particulate amniotic membrane and umbilical cord (AM/UC) matrix could aid in attenuating disease progression. Lewis rats underwent medial meniscus transection (MMT) to induce OA. Two weeks after surgery, animals received intra-articular injections (50 μL) of either 50 µg/µL or 100 µg/µL particulate AM/UC or saline control and were subsequently euthanized 1 or 4 weeks later...

: This study showed that autoimmune arthritis induces especially severe osteoporosis in the periarticular region adjacent to inflamed joints, suggesting that arthritis increases the fragility fracture risk near inflamed joints, which is frequently observed in patients with RA. INTRODUCTION: Periarticular osteoporosis near inflamed joints is a hallmark of early rheumatoid arthritis (RA). Here we show that rheumatic inflammation deteriorates the bone quality and bone quantity of periarticular bone, thereby decreasing bone strength and toughness in a mouse model of RA...
