    Conventional medical therapies for osteoarthritis are mainly palliative in nature, aiming to control pain and symptoms. Traditional intra-articular therapies are not recommended in guidelines as first line therapy, but are potential alternatives, when conventional therapies have failed. Current and future intra-articular drug therapies for osteoarthritis are highlighted, including corticosteroids, hyaluronate, and more controversial treatments marketed commercially, namely platelet rich plasma and mesenchymal cell therapy. Intraarticular disease modifying osteoarthritis drugs are the future of osteoarthritis treatments, aiming at structural modification and altering the disease progression. Interleukin-1β inhibitor, bone morphogenic protein-7, fibroblast growth factor 18, bradykinin B2 receptor antagonist, human serum albumin, and gene therapy are discussed in this review. The evolution of drug development in osteoarthritis is limited by the ability to demonstrate effect. High quality trials are required to justify the use of existing intra-articular therapies and to advocate for newer, promising therapies. Challenges in osteoarthritis therapy research are fundamentally related to the complexity of the pathological mechanisms of osteoarthritis. Novel drugs offer hope in a disease with limited medical therapy options. Whether these future intra-articular therapies will provide clinically meaningful benefits, remains unknown.

    Full text: The objective of this study is to determine the therapeutic efficacy of radiosynovectomy on rheumatoid and hemophilic arthropathy as compared to the usual intra-articular steroids on painful joints. Rheumatoid arthritis is a chronic, systemic and inflammatory disease that involves the joints and is quite disabling. It has a worldwide prevalence of 1%. Hemophilia is a congenital blood disease that produces abnormal bleeding at the musculoskeletal level. It is a sex-linked trait that cause coagulation defects brought about by lack of Factor Vlll for Hemophilia A and Factor lX for Hemophilia B. In this study, under the auspices of IAEA, we used Yttrium 90 colloids and Rhenium 188 intra-articularly in the knee in the experimental group and steroids on the control group. Radioactive colloids (beta radiation) create fibrosis of the hypertrophic and highly vascularized synovium. It leads to coagulation necrosis and sloughing of the cells, destroying diseased pannus and inflamed synovium with the hope that the regenerating synovium, after destruction, will be free of the disease. Included in this study were established cases of RA set by the American Rheumatoid Assn which are stage 1, 2, and 3 by Larsen classification, no ankylosis, non-responders for NSAIDS and DMARDS for at least 6 months and with their informed consent. For the hemophilic group, they should have at least 3 bleeding episodes for the last six months and at least with 30% coagulopathy at the time of the procedure. Exclusion criteria included being pregnant or lactating, with infection on site of injection, beyond stage 3 and presence Baker's cyst. Baseline radiography and two-phase bone scans were taken as well as repeating these procedures at 6 an 12 months post-treatment. There were 39 evaluable patients under the experimental group consisting of 18 RA patients (mostly females) and 21 HA patients (all males). Thirty-eight patients were given Yttrium-90 colloid with doses ranging from 60 Mbq to

    Full Text Available In this review the main stages in the history of intra-articular therapy of the rheumatic diseases are summarized. The first approach to such a local treatment has been likely performed in 1792 by the French physician Jean Gay, who injected in a swelling knee the “eau du Goulard” (Goulard’s water, namely a mixture based on lead compounds. In the XIX century iodine derivatives have been mainly applied as an intra-articular treatment. In the XX century, before the wide use of intra-articular corticosteroids, chiefly due to the Joseph Lee Hollander’s experiences, a variety of drugs has been employed, including cytostatics and sclerosing substances. A further important stage has been synoviorthesis, by using specific radionuclides, that would actually represent an anti-synovial treatment. In the last years a spread use of intra-articular hyaluronic acid, particularly in osteoarthritis, has been recorded, with the aim to warrant articular viscosupplementation. Future of intra-articular treatment should be represented by the biological drugs, i.e., anti-TNF, but it is still untimely to define the exact role of such a local treatment of arthritis.

    Full Text Available OBJECTIVE: The aim of the study was to identify the main aspects involved in patient selection, the choice of therapeutic agents and the safety profile, as well as the medico-legal and organizational aspects of intra-articular injection therapies for osteoarthritis. METHODS: A committee of 10 experts from Italian universities, public hospitals, territorial services, research institutes and patient associations was set up. Fifty-two clinicians from a large number of Italian medical centers specialized in intra-articular injection therapy took part in a Delphi process aimed at obtaining consensus statements among the participants. RESULTS: Large consensus was obtained for statements grouped under the following main themes: treatment indications; drug/medical device choice; treatment efficacy; and appropriate setting. CONCLUSIONS: The consensus statements developed by a large number of experts may be used as a practical reference tool to help physicians treat osteoarthritis patients by means of intra-articular injection therapies.

    This study supports the existing literature and suggests that the use of IV Tranexamic acid alone or in combination with intra-articular dose in TKA may reduce the requirement for transfusion (Level IV evidence. Furthermore, this study suggests that the use of tranexamic acid as a combination of Intravenous and intra-articular administration has no effect on range of motion, or medical complications during hospital stay. Although it was not a statistically significant finding, our study suggested a trend towards a greater reduction in haemoglobin and haematocrit fall in the combination therapy group when compared to IV Tranexamic acid alone

    Rotator cuff problems are common causes of pain and restriction of movement in shoulder. The aim of this study to compare the effect of intra-articular injection of corticosteroid and conventional transcutaneous electrical nerve stimulator (TENS) treatment in treatment of rotator cuff tendinitis. Subjects were randomly allocated into Group 1 (intra-articular injection of corticosteroid) and Group 2 (conventional transcutaneous electrical nerve stimulation-TENS). Outcome measurements were performed using the Visual Analogue Scale (VAS) for pain, range of motion (ROM), the Shoulder Disability Questionnaire (SDQ), the Short Form-36 (SF-36), and Beck Depression Scale (BDS) questionnaires and paracetamol consumption. In both groups, significant improvement was observed in all weeks in VAS, ROM and SDQ scores (P0.05). In both treatment groups, paracetamol consumption decreased in time (Protator cuff tendinitis. When two treatments are compared, it may be concluded that intra-articular steroid injection was more effective especially in the first weeks regarding pain, ROM and disability. Otherwise, use of TENS allow to patients to increase activity level, improve function and quality of life like that in our study. TENS, as it is cheaper, non-invasive, more easily performed and efficient, may be preferable for the treatment of shoulder pain. Further studies are needed to include these results in the prospective treatment guidelines.

    Objective: To assess the value of sonographic criteria, based on measurements of joint capsule distension and synovial hyperemia, during the course of repeated ultrasound (US)-guided intra-articular injections of hyaluronic acid (HA) in hand osteoarthritis (OA). Materials and methods: Thirty-three patients (28 females/5 males), with hand OA in 78 joints, were included in this study. Patients underwent sonographic evaluation at baseline and consecutively for 4 weeks at weekly US-guided intra-articular injections of HA (Hyalgan ® ). Measurements of joint thickening and joint inflammation were performed with Grey-scale and semi-quantitative Power-Doppler US (PDUS). Sonographic values were correlated with weekly patients self-assessment of pain for each treated joint. Results: The mean (SD) patients self-assessment of pain statistically significantly (p < 0.0001) decreased from the first [68.3(22.3)] to the last week [37.3(30.34)]. A steady pain relief could be noticed in 67 (86%) of all treated joints. Over the whole observation period, the mean (SD) joint thickening of all joints markedly decreased from 15.6 mm (5.3) to 13.1 mm (6.4) (p < 0.0001). The PDUS-score before initiation of HA treatment was statistically significantly higher than at the end of therapy (p < 0.0001). The decrease in pain statistically significantly correlated with the decrease of joint thickening and PDUS-score between baseline and the end of therapy (p < 0.001). Conclusion: In this study, we demonstrate the meaningfulness of sonographic evaluation criteria including measurements of joint capsule distension and PDUS vascularization, both significantly correlating with the decrease of pain, during the therapy follow-up of US-guided intra-articular HA-injections in patients with hand OA.

    Treatment with intravenous enzyme replacement therapy and hematopoietic stem cell transplantation for mucopolysaccharidosis (MPS) type I does not address joint disease, resulting in persistent orthopedic complications and impaired quality of life. A proof-of-concept study was conducted to determine the safety, tolerability, and efficacy of intra-articular recombinant human iduronidase (IA-rhIDUA) enzyme replacement therapy in the canine MPS I model. Four MPS I dogs underwent monthly rhIDUA injections (0.58 mg/joint) into the right elbow and knee for 6 months. Contralateral elbows and knees concurrently received normal saline. No intravenous rhIDUA therapy was administered. Monthly blood counts, chemistries, anti-rhIDUA antibody titers, and synovial fluid cell counts were measured. Lysosomal storage of synoviocytes and chondrocytes, synovial macrophages and plasma cells were scored at baseline and 1 month following the final injection. All injections were well-tolerated without adverse reactions. One animal required prednisone for spinal cord compression. There were no clinically significant abnormalities in blood counts or chemistries. Circulating anti-rhIDUA antibody titers gradually increased in all dogs except the prednisone-treated dog; plasma cells, which were absent in all baseline synovial specimens, were predominantly found in synovium of rhIDUA-treated joints at study-end. Lysosomal storage in synoviocytes and chondrocytes following 6 months of IA-rhIDUA demonstrated significant reduction compared to tissues at baseline, and saline-treated tissues at study-end. Mean joint synovial GAG levels in IA-rhIDUA joints were 8.62 ± 5.86 μg/mg dry weight and 21.6 ± 10.4 μg/mg dry weight in control joints (60% reduction). Cartilage heparan sulfate was also reduced in the IA-rhIDUA joints (113 ± 39.5 ng/g wet weight) compared to saline-treated joints (142 ± 56.4 ng/g wet weight). Synovial macrophage infiltration, which was present in all joints at baseline, was

    It is debated whether intra-articular viscosupplementation with hyaluronic acid (HA) can lead to improvements in subjects with osteoarthritis (OA) undergoing physical and rehabilitative interventions. To assess the effects of intra-articular viscosupplementation on disability in subjects with OA undergoing physical and rehabilitative interventions. Information on pain and quality of life were also collected. The databases of PubMed, Medline, EMbase and CINAHL were searched for English language full-text randomized controlled trials comparing intra-articular viscosupplementation alone or associated with physical and rehabilitative interventions to viscosupplementation alone, shame treatment, waiting lists, and any type of rehabilitative interventions. Methodological quality of each study was assessed by using the Physiotherapy Evidence Database (PEDro) Scale. A total of 115 references were retrieved, and 8 studies were selected. Three trials compared HA injection and physical therapy in knee OA, with disability and pain improvements in all studies, and between-group differences in favor of physical therapy in two studies; two trials compared HA injection and home exercises in knee OA, with improvements in pain, disability and quality of life in all studies, without between-group differences; two trials compared HA injection plus physical therapy agents and exercises to exercises plus physical therapy agents in knee OA, with improvements in disability and pain in both studies, and between-group differences in favor of the inclusion HA in one study; one trial compared HA injection and home exercises in ankle OA, with improvements in disability and pain in both arms without between-group differences. Physical therapy agents seemed to have greater effects than intra-articular viscosupplementation on disability and pain. In the other cases both intra-articular viscosupplementation and physical and rehabilitative interventions seemed to be equally effective in improving

    The present study investigated intra-articular injection of bone-marrow-derived mesenchymal stem cells (MSCs) combined with articulated joint distraction as treatment for osteochondral defects. Large osteochondral defects were created in the weight-bearing area of the medial femoral condyle in rabbit knees. Four weeks after defect creation, rabbits were divided into six groups: control group, MSC group, distraction group, distraction + MSC group, temporary distraction group, and temporary distraction + MSC group. Groups with MSC received intra-articular injection of MSCs. Groups with distraction underwent articulated distraction arthroplasty. Groups with temporary distraction discontinued the distraction after 4 weeks. The rabbits were euthanized at 4, 8, and 12 weeks after treatment except temporary distraction groups which were euthanized at only 12 weeks. Histological scores in the distraction + MSC group were significantly better than in the control, MSC group or distraction group at 4 and 8 weeks, but showed no further improvement. At 12 weeks, the temporary distraction + MSC group showed the best results, demonstrating hyaline cartilage repair with regeneration of the osteochondral junction. In conclusion, joint distraction with intra-articular injection of MSCs promotes early cartilage repair, and compressive loading of the repair tissue after temporary distraction stimulates articular cartilage regeneration. © 2015 Orthopaedic Research Society.

    The purpose of this study was to present clinical and MR imaging features of intra-articular ganglion cysts of the knee. Retrospective review of 1685 consecutive medical records and MR examinations of the knee performed at three imaging centers allowed identification of 20 patients (13 men and 7 women; mean age 35 years), in whom evidence of intra-articular ganglion cyst was seen. Of the 20 ganglion cysts, 5 were found in the infrapatellar fat pad, 10 arose from the posterior cruciate ligament, and 5 from the anterior cruciate ligament. Three of five patients with ganglion cyst in the infrapatellar fat pad had a palpable mass. In 7 of 15 patients with ganglion cyst in the intercondylar notch, exacerbation of pain occurred in a squatting position. On four MR arthrographies, ganglion cysts were an intra-articular round, lobulated, low signal intensity lesion. Five cases of fat-suppressed contrast-enhanced T1-weighted SE images demonstrated peripheral thin rim enhancement. The clinical presentation of intra-articular ganglion cyst is varied according to its intra-articular location. The MR appearance of intra-articular ganglion cyst is characteristic and usually associated with the cruciate ligament or the infrapatellar fat pad. Magnetic resonance arthrography has no definite advantage over conventional MR in the evaluation of the lesion. For intra-articular ganglion cyst in the infrapatellar fat pad, fat-suppressed contrast-enhanced MR imaging could be useful, because a thin, rim-enhancing feature of intra-articular ganglion cyst allows it to be distinguished from synovial hemangioma and synovial sarcoma.

    separated by a three week washout period. Before each treatment, radiocarpal synovitis was induced by IA injection of lipopolysaccharide (LPS). For each of the two 168-hours study periods, local and systemic measures of pain and inflammation as well as blood and synovial fluid (SF) samples...... for pharmacological analysis were obtained repeatedly. Pain was evaluated by degree of lameness as well as using a visual analogue scale of pain intensity (VAS) and a composite measure pain scale (CMPS), developed for this purpose. Intra-articular injection of LPS elicited a marked synovitis resulting in lameness...... and pain. Intra-articularly administered morphine showed a significant analgesic effect as measured by reduced lameness scores, less administered rescue analgesia and lower pain scores. A significant anti-inflammatory effect was demonstrated by reduced joint swelling, reduced SF serum amyloid A (SAA...

    Knee osteoarthritis is a leading cause of chronic pain, disability, and decreased quality of life. Despite the long-standing use of intra-articular corticosteroids, there is an ongoing debate about their benefits and safety. This is an update of a Cochrane review first published in 2005. To determine the benefits and harms of intra-articular corticosteroids compared with sham or no intervention in people with knee osteoarthritis in terms of pain, physical function, quality of life, and safety. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, and EMBASE (from inception to 3 February 2015), checked trial registers, conference proceedings, reference lists, and contacted authors. We included randomised or quasi-randomised controlled trials that compared intra-articular corticosteroids with sham injection or no treatment in people with knee osteoarthritis. We applied no language restrictions. We calculated standardised mean differences (SMDs) and 95% confidence intervals (CI) for pain, function, quality of life, joint space narrowing, and risk ratios (RRs) for safety outcomes. We combined trials using an inverse-variance random-effects meta-analysis. We identified 27 trials (13 new studies) with 1767 participants in this update. We graded the quality of the evidence as 'low' for all outcomes because treatment effect estimates were inconsistent with great variation across trials, pooled estimates were imprecise and did not rule out relevant or irrelevant clinical effects, and because most trials had a high or unclear risk of bias. Intra-articular corticosteroids appeared to be more beneficial in pain reduction than control interventions (SMD -0.40, 95% CI -0.58 to -0.22), which corresponds to a difference in pain scores of 1.0 cm on a 10-cm visual analogue scale between corticosteroids and sham injection and translates into a number needed to treat for an additional beneficial outcome (NNTB) of 8 (95% CI 6 to 13).

    Aim: To demonstrate the benefits of fluoroscopy-guided intra-articular steroid injection in the hip with varying degrees of disease severity, and to investigate the financial aspects of the procedure and impact on waiting time. Materials and methods: A prospective study was undertaken of patients who underwent fluoroscopic intra-articular steroid injection over the 9-month study period. Comparative analysis of the Oxford hip pain score pre- and 6–8 weeks post-intra-articular injection was performed. Hip radiographs of all patients were categorised as normal, mild, moderate, or severe disease (four categories) based on the modified Kellgren–Lawrence severity scale, and improvement on the Oxford hip pain score on each of these four severity categories were assessed. Results: Within the study cohort of 100 patients, the mean increase in post-procedure hip score of 7.32 points confirms statistically significant benefits of the therapy (p<0.001, 95% confidence interval: 5.55–9.09). There was no significant difference in pre-injection hip score or change in score between the four severity categories (p=0.51). Significant improvement in hip score (p<0.05) was demonstrated in each of the four severity categories 6–8 weeks post-injection. No associated complications were observed. Conclusion: The present study confirms that fluoroscopy-guided intra-articular steroid injection is a highly effective therapeutic measure for hip osteoarthritis across all grades of disease severity with significant cost savings and the potential to reduce waiting times. - Highlights: • Comparable clinical effectiveness of fluoroscopy guided and theatre based therapeutic intra-articular hip injections. • Significant cost savings on fluoroscopy guided hip injection performed in a radiology department. • A potential reduction in patients' waiting time for the procedure.

  19. Intra-Articular Viscosupplementation With Hylan G-F 20 To Treat Osteoarthritis of the Knee

    2005-01-01

    Executive Summary Objective To assess the effectiveness and cost-effectiveness of hylan G-F 20 as a substitute for existing treatments for pain due to osteoarthritis (OA) of the knee, other viscosupplementation devices, and/or as an adjunct to conventional therapy. Hylan G-F 20 (brand name Synvisc, which is manufactured by Genzyme) is a high molecular weight derivative of hyaluronan, a component of joint synovial fluid. It acts as a lubricant and shock absorber. It is administered by injection into the joint space to treat pain associated with OA of the knee. Although the injection procedure is an insured service in Ontario, the device, hylan G-F 20, is not. Clinical Need Osteoarthritis is prevalent in 10% to 12% of Ontario adults, and exceeds 40% in Ontario residents aged 65 years and older. About one-half of these people have mild, moderate, or severe OA of the knee. Conventional treatment involves a combination of nonpharmacological management (e.g., weight loss, exercise, social support, and patient education), drugs, (e.g., acetaminophen, COX-2 inhibitors, nonsteroidal anti-inflammatory drugs with/without misoprostol, intra-articular glucocorticoids, opioids, and topical analgesics) and surgical interventions, such as debridement and total knee replacement, when pharmacological management fails. The growing burden of OA of the knee in the aging Ontario population combined with recent safety concerns about COX-2 inhibitors and long wait times for total joint replacement is placing pressure on the demand for new, effective technologies to manage the pain of OA. The Technology Hylan G-F 20 is derived from rooster comb hyaluronan (HA). At the time of writing, eight viscosupplement hyaluronic products are licensed in Canada. Hylan G-F 20 is distinguished from the other products by its chemical structure (i.e., cross-linked hyaluronan, hence hylan) and relatively higher molecular weight, which may bestow greater therapeutic viscoelastic properties.

    The aim of this retrospective study was to investigate the frequency of intra-articular osteoid osteoma (iaOO) in a large study cohort and to demonstrate its clinical relevance as an important differential diagnosis of non-specific mono-articular joint pain. We searched the registry for bone tumours of the University Medical Centre Hamburg-Eppendorf for osteoid osteomas in the last 42 years. Herein, we present three selected iaOO which were detected in the three major weight-bearing joints. Computed tomography (CT) or magnetic resonance imaging (MRI) scans were performed for initial diagnosis. Out of a total of 367 osteoid osteomas, 19 (5.2 %) tumours were localized intra-articularly. In all three presented tumours, a history of severe mono-articular pain was reported; however, the mean time to correct diagnosis was delayed to 20.7 months. Clearly, the nidus seen in CT and MRI images in combination with inconsistent salicylate-responsive nocturnal pain led to the diagnosis of iaOO. Rarely, osteoid osteoma can occur in an intra-articular location. In cases of diffuse mono-articular pain, iaOO should be considered both in large and smaller joints to avoid delays in diagnosis and therapy of this benign bone tumour.

    2015-04-01

    Osteoarthritis of the knee can be a debilitating and extremely painful condition. In patients who desire to postpone knee arthroplasty or in those who are not surgical candidates, percutaneous knee injection therapies have the potential to reduce pain and swelling, maintain joint mobility, and minimize disability. Published studies cite poor accuracy of intra-articular knee joint injections without imaging guidance. We present a sonographically guided posteromedial approach to intra-articular knee joint injections with 100% accuracy and no complications in a consecutive series of 67 patients undergoing subsequent computed tomographic or magnetic resonance arthrography. Although many other standard approaches are available, a posteromedial intra-articular technique is particularly useful in patients with a large body habitus and theoretically allows for simultaneous aspiration of Baker cysts with a single sterile preparation and without changing the patient's position. The posteromedial technique described in this paper is not compared or deemed superior to other standard approaches but, rather, is presented as a potentially safe and efficient alternative. © 2015 by the American Institute of Ultrasound in Medicine.

    Full Text Available Intra-articular osteotomy is considered in the rare case of malunion after a fracture of the distal humerus to restore humeral alignment and gain a functional arc of elbow motion. Traumatic and iatrogenic disruption of the limited blood flow to the distal end of the humerus resulting in avascular necrosis of capitellum or trochlea is a major pitfall of the this technically challenging procedure. Two cases are presented which illustrate the potential problems of intra-articular osteotomy for malunion of the distal humerus.

    Peroneal tendon displacement (subluxation or dislocation) accompanying an intra-articular calcaneal fracture is often undetected and under-treated. The goals of this study were to determine (1) the prevalence of peroneal tendon displacement accompanying intra-articular calcaneal fractures, (2) the association of tendon displacement with fracture classifications, (3) the association of tendon displacement with heel width, and (4) the rate of missed diagnosis of the tendon displacement on radiographs and computed tomography (CT) scans and the resulting treatment rate. A retrospective radiographic review of all calcaneal fractures presenting at three institutions from June 30, 2006, to June 30, 2011, was performed. CT imaging of 421 intra-articular calcaneal fractures involving the posterior facet was available for review. The prevalence of peroneal tendon displacement was noted and its associations with fracture classification and heel width were evaluated. Peroneal tendon displacement was identified in 118 (28.0%) of the 421 calcaneal fracture cases. The presence of tendon displacement was significantly associated with joint-depression fractures compared with tongue-type fractures (p displacement had been identified in the radiology reports. Although sixty-five (55.1%) of the fractures with tendon displacement had been treated with internal fixation, the tendon displacement was treated surgically in only seven (10.8%) of these cases. Analysis of CT images showed a 28% prevalence of peroneal tendon displacement accompanying intra-articular calcaneal fractures. Surgeons and radiologists are encouraged to consider this association.

    This systematic review aimed to investigate whether intra-articular injections of hyaluronic acid (HA) are better than other drugs used in temporomandibular joint arthrocentesis, for the improvement of temporomandibular disorder (TMD) symptoms. Two independent reviewers performed an electronic search of the MEDLINE and Web of Science databases for relevant studies published in English up to March 2016. The key words used included a combination of 'hyaluronic acid', 'viscosupplementation', 'intra-articular injections', 'corticosteroids', or 'non steroidal anti inflammatory agents' with 'temporomandibular disorder'. Selected studies were randomized clinical trials and prospective or retrospective studies that primarily investigated the application of HA injections compared to other intra-articular medications for the treatment of TMD. The initial screening yielded 523 articles. After evaluation of the titles and abstracts, eight were selected. Full texts of these articles were accessed and all fulfilled the inclusion criteria. Intra-articular injections of HA are beneficial in improving the pain and/or functional symptoms of TMDs. However, other drug therapies, such as corticosteroid and non-steroidal anti-inflammatory drug injections, can be used with satisfactory results. Well-designed clinical studies are necessary to identify an adequate protocol, the number of sessions needed, and the appropriate molecular weight of HA for use.

    The purpose of this study was to document and compare the incidence of intra-articular hip pathologic findings identified using arthroscopy versus conventional imaging in patients with acute trauma to the hip. This was a blinded prospective case series study designed to review the incidence of intra-articular pathologic disorders in patients with post-traumatic injury between the ages of 18 and 65 years who were referred to a single surgeon. Injuries included hip dislocation, proximal femur fracture, pelvic ring fracture, acetabular fracture, penetrating injury (gunshot wound), and soft tissue injury. Preoperative radiographs, computed tomographic (CT) scans, or magnetic resonance imaging/magnetic resonance angiography (MRI/MRA) scans (or a combination of these) were obtained. Findings were documented and compared with intraoperative findings. A total of 29 post-traumatic hips were enrolled in this study. Hip arthroscopy identified 17 of 29 hips (59%) as having loose bodies, 11 of 29 (38%) hips as having an intra-articular step deformity, 14 of 29 (49%) hips as having an osteochondral lesion, and 27 of 29 (93%) hips as having a labral tear. Plain radiographs and CT scans yielded low sensitivity when compared with arthroscopy for the identification of loose bodies and step deformities. MRI/MRA comparison with arthroscopic findings suggest that MRI/MRA is an accurate tool for identification of labral tears, because 91% of tears seen on arthroscopy were also identified by MRI/MRA. In 4 hips, however, MRI/MRA failed to identify osteochondral lesions that were subsequently identified by arthroscopy. Traumatic injuries of the hip result in substantial intra-articular pathologic findings, including loose bodies, labral tears, step deformities, and osteochondral lesions. The arthroscope is a powerful tool in identifying these injuries. Plain radiographs and CT scans appear to underestimate the true incidence of loose bodies and step deformities within the joint when

    OBJECTIVE: To control local inflammation, the role of intra-articular corticosteroid is well established; similarly, with time there are more reports on the experience of intra-articular anti-TNF agent for localized joint inflammation. The aim of this study was to assess the safety, local tolerability and clinical response after combining intra-articular administration of corticosteroids and anti-TNF agents for recurrent inflammatory monoarthritis. METHODS: Patients with recurrent monoarthritis of the knee were recruited from our inflammatory arthritis clinics. These patients required intra-articular corticosteroids every 8-12 weeks, with good short-term results. Five such consecutive patients were invited to partake in this study. Patients were maintained on their baseline immunosuppressive therapy. After aspiration of knee joint, the involved joint was injected with 80mg of methylprednisolone mixed with 5ml of lignocaine 1%; this was followed by the injection of an anti-TNF agent. RESULTS: In majority of our patients (three out of five), combining anti-TNF agent and methylprednisolone led to prolonged anti-inflammatory response, and these patients remain in remission to date (mean follow-up of 12 months). These responders were noted to be naive to anti-TNF therapy. Conversely, the remaining two patients were found to be on baseline systemic anti-TNF therapy, and both of them failed to respond either partly or completely. CONCLUSION: Combining intra-articular corticosteroid and anti-TNF agent has proved to be safe in our cohort of patients. We conclude that in particular subset of patients who suffer from recurrent inflammatory monoarthritis or oligoarthritis, combination therapy of intra-articular corticosteroids and anti-TNF agents appears attractive and promising.

    The goal of this study was to identify baseline prognostic factors of outcome in ankle osteoarthritis patients after intra-articular hyaluronic acid injection. Patients with ankle osteoarthritis who received hyaluronic acid injection therapy were retrospectively reviewed. Each patient received weekly intra-articular hyaluronic acid injections (2 mL) for 3 weeks. Six predictors including gender, age, symptom duration, radiographic osteoarthritis stage, radiographic subchondral cyst, and fracture history were evaluated. Visual analogue scale (VAS) and patient satisfaction were evaluated as outcome measures. These predictors and outcome measurements were included in a logistic regression model for statistical analysis. Total of 40 consecutive patients (21 male, 19 female) were included in this study. Mean age was 60.6. Average follow up period was 13 months. The mean VAS recorded 3, 6, and 12 months after the first injection was 3.6 (SD 2.54, phyaluronic acid injection for ankle osteoarthritis is a safe and effective treatment, careful selection of patients should be made according to the above prognostic predictors.

    The aim of this study was to evaluate the benefit provided by intraosseous infiltration combined with intra-articular injection of platelet-rich plasma to treat mild and moderate stages of knee joint degeneration (Kellgren-Lawrence score II-III) compared with other treatments, specifically intra-articular injection of PRP and of HA. Eighty-six patients with grade II to grade III knee OA according to the Kellgren-Lawrence classification were randomly assigned to intra-articular combined with intraosseous injection of PRP (group A), intra-articular PRP (group B), or intra-articular HA (group C). Patients in group A received intra-articular combined with intraosseous injection of PRP (administered twice, 2 weeks apart). Patients in group B received intra-articular injection of PRP every 14 days. Patients in group C received a series of five intra-articular injections of HA every 7 days. All patients were evaluated using the Visual Analogue Scale (VAS) and Western Ontario and McMaster Universities (WOMAC) score before the treatment and at 1, 3, 6, 12, and 18 months after treatment. There were significant improvements at the end of the 1st month. Notably, group A patients had significantly superior VAS and WOMAC scores than were observed in groups B and C. The VAS scores were similar in groups B and group C after the 6th month. Regarding the WOMAC scores, groups B and C differed at the 1st, 3rd, 6th, and 12th months; however, no significant difference was observed at the 18th month. The combination of intraosseous with intra-articular injections of PRP resulted in a significantly superior clinical outcome, with sustained lower VAS and WOMAC scores and improvement in quality of life within 18 months.

    Regenerative medicine has become one of the most promising therapies of equine osteoarthritis. Platelet lysate (PL) is rich in bioactive proteins and growth factors that play a crucial role in tissue healing. To evaluate the efficacy of intra-articularly injected autologous PL in equine athletes with naturally occurring osteoarthritis. Fifteen warmblood geldings aged 8-19 years with osteoarthritis of the distal interphalangeal joint were included in this study. They were randomly divided into two groups; 10 horses received intra-articular injections of PL and 5 of normal saline (controls). Before treatment, platelet-derived growth factor (PDGF) levels in basal plasma and prepared PL were estimated. Each joint was injected twice within a three-week period. Lameness was evaluated using the American Association of Equine Practitioners grading system, before treatment and 10 days after each intra-articular injection. Horses were examined fortnightly for one year. Radiographic examination was performed six months post-treatment. The generalized estimating equation test was used for statistical analysis. Acceptable levels of PDGF were detected in PLs (mean ± SD: 258.0 ± 52.3 pg/ml). The majority of horses (9/10) responded positively to PL treatment presenting lower lameness grades (p < 0.0005) compared to controls 10 days after the second injection, and returned to normal athletic activity. Radiographs revealed no changes in osteoarthritis lesions six months after treatment. One year post-injections, however, all horses relapsed to their initial degree of lameness. Intra-articularly injected autologous PL is an efficient method for temporarily managing osteoarthritis of the distal interphalangeal joint in athletic horses.

    Full Text Available Mechanisms to reduce lameness associated with osteoarthritis (OA are vital to equine health and performance. This study was designed to quantify response to autologous, intra-articular platelet-rich plasma (PRP in horses with OA. Kinetic gait analysis was performed on 12 horses with unilateral forelimb lameness and OA in the same limb before and after intra-articular anesthesia (IAA. Radiographs and kinetic data were obtained before, 6 and 16 weeks after PRP administration to same joint 4 weeks after IAA. Statistical evaluations included filtration effect on platelet concentration, relationship between kinetic variable changes after IAA versus PRP in the affected limb, and associations between response to PRP and response to IAA, platelet concentration and radiographic OA. A positive response to IAA or PRP was defined as ≥5% improvement in peak vertical force, vertical impulse or breaking impulse of the affected limb. Out of 10 horses that responded to IAA, 4 responded to PRP at both time points and 2 responded at one. Of 2 horses that did not respond to IAA, one responded to PRP at both time points. Filtration increased platelet concentration significantly. The relationship between kinetic variable alterations of the affected limb after IAA and PRP was not significant, and response to PRP was not associated with response to IAA, platelet concentration or radiographic OA. Changes in kinetic variables following IAA in joints with naturally occurring OA provide a custom standard to assess intra-articular therapy. Kinetic gait changes after intra-articular PRP are variable in horses with moderate to severe forelimb OA.

    Intra-articular injection of hyaluronic acid is a well-established therapy for the treatment of knee osteoarthritis. The aim of the study was to assess the effectiveness and safety of the use of Arthrum HCS(®) (40 mg hyaluronic acid and 40 mg chondroitin sulfate in 2 mL). This was an open, multicenter, prospective study. Men or women over 40 years of age with documented knee osteoarthritis and WOMAC subscore A (severity of pain) ≥25 were enrolled. They received three weekly intra-articular injections of sodium hyaluronate 2 % and chondroitin sulfate 2 % in combination. WOMAC subscore A was assessed at 1, 3 and 6 months after the last injection. One hundred and twelve patients were included (women, 66 %). The mean (SD) WOMAC subscore A decreased from 52.1 (15.2) at inclusion to 20.5 (19.7) at month 6 (P chondroitin sulfate in reducing pain (77 %), improving mobility (78 %) and reducing the consumption of analgesics (74 %). Only one adverse effect was reported by one patient (knee tumefaction). These results suggest that intra-articular injections of Arthrum HCS(®) (sodium hyaluronate plus chondroitin sulfate) in patients with knee osteoarthritis are efficient and safe. These results should be confirmed in a randomized controlled study. IV.

    The purpose of this study was to assess the value of intra-articular fluid injection under pressure, as a technique suggested for temporo-mandibular joint (TMJ) closed-lock treatment, and to determine if there is a persisting lock resolution in time. Twelve patients were studied at our centre, with a diagnosis of TMJ closed-lock, not amenable with conventional therapies. All patients underwent a MRI scan, confirming the presence of anteriorly displaced disk. This technique is based on intra-articular injection of anaesthetic (mepivacaine cloridrate) under pressure, using the so called pumping technique, that allows an inferior distraction of the condyle. The study has a six months follow-up. After closed-lock resolution all patients underwent physiotherapy with guided mouth opening, for one month. Mandibular function (maximal mouth opening) increased on average of 20.2 mm after treatment, and of 21.1 mm six months later (p=0.00000; with p<0.005). Pain decreased on average from VAS=6.75 to VAS=0.3 (p=0.00001; with p<0.005). The masticatory efficiency improved from VAS=5.25 to VAS=8.75 (p=0.002; p<0.005). Functional TMJ limitation level is significantly increased (p=0.002; p<0.005). Also, patient's efficacy judgement (mean value 3.58= good) and tolerability judgement (mean value 2.92=good) indicate that this therapy is well accepted. This technique is easy to perform, well tolerated and does not need specific instruments: it permits the resolution of TMJ closed-lock, decreases the pain and improves masticatory efficiency. All these effects persist in time. Subjects with recent closed-lock have an immediate and complete functional recovery while patients with chronic closed-lock do not.

    Tissue necrosis is a rare yet potentially serious complication of intra-articular (IA) hyaluronic acid (HA) injections for treatment of knee osteoarthritis. To report a case of a patient with cutaneous necrosis after IA HA injection for treatment of knee osteoarthritis, presenting as a livedoid violaceous patch on the right knee. We report a case of cutaneous necrosis as a rare complication of IA HA injection for treatment of knee osteoarthritis. A literature review was undertaken of similar cases. Use of HA IA injections in the treatment of osteoarthritis can result in similar skin necrosis at uncommon anatomic locations corresponding to the site of HA injection. Although tissue necrosis is a rare complication, physicians need to be aware of this possibility as a complication of HA IA injections in the treatment of osteoarthritis and should be mindful of potential treatment options to manage this adverse event. © 2014 Canadian Dermatology Association.

    Full Text Available Osteoarthritis is a chronic disorder characterized by joint cartilage degeneration with concomitant changes in the synovium and subchondral bone metabolism. Many conservative treatment modalities, one of which is intra-articular injections, have been described for the treatment of this disorder. Traditionally, hyaluranic acid and corticosteroids are the agents that have been used for this purpose. Recently, polyacrylamide hydrogels are being used widely. Biocompatibility, nonbioabsorbability, and anti-infectious effect obtained by silver addition made polyacrylamide hydrogels more popular. In this paper, we present a case and the method of our management, in whom host tissue reaction (foreign body granuloma, edema, inflammation, and redness induration has been observed, as the first and unique adverse effect reported in the literature.

    Full Text Available Introduction: Primary therapeutic aim in treatment of osteoarthritis of the knee is to relieve the pain of osteoarthritis. The aim of this study was to compare the efficacy of intra-articular triamcinolone with intra-articular morphine in pain relief due to osteoarthritis of the knee in the elderly population. Materials and Methods: Patients between 50 and 80 years of age were randomized into three groups. Group M received morphine plus bupivacaine intra-articularly, Group T received triamcinolone plus bupivacaine intra-articularly, and Group C received saline plus bupivacaine intra-articularly. Patients were evaluated before injection and in 2nd, 4th, 6th, and 12th weeks after injection. First-line supplementary analgesic was oral paracetamol 1500 mg/day. If analgesia was insufficient with paracetamol, oral dexketoprofen trometamol 50 mg/day was recommended to patients. Results: After the intra-articular injection, there was statistically significant decrease in visual analog scale (VAS scores in Groups M and T, when compared to Group C. The decrease of VAS scores seen at the first 2 weeks continued steadily up to the end of 12th week. There was a significant decrease in Groups M and T in the WOMAC scores, when compared to Group C. There was no significant difference in the WOMAC scores between morphine and steroid groups. Significantly less supplementary analgesics was used in the morphine and steroid groups. Conclusion: Intra-articular morphine was as effective as intra-articular triamcinolone for analgesia in patients with osteoarthritis knee. Intra-articular morphine is possibly a better option than intra-articular steroid as it has lesser side effects.

    The purpose of our study was to investigate the role of intra-articular pulse-dose radiofrequency in management of painful hallux valgus refractory to conservative therapies. Between November 2010 and April 2012, 51 patients (15 male, 36 female) with a median age of 71.4 years were included in our clinical trial. Under fluoroscopic guidance we introduced a 22 gauge 10 cm length cannula by a percutaneous access in the first metatarsophalangeal joint and its tip was placed intra-articularly. After removing the spindle, a radiofrequency needle with a 5 mm active tip was introduced. The following parameters were used: 1200 pulses at high voltage (45 V) with 20 msec duration followed by 480 msec silent phases. A great reduction in pain intensity was documented at 1 week, 1 month and 3 months after procedures. Pain intensity increased between 5 and 8 months after treatments, so we performed a second procedure in all patients between 7 months and 9 months since the first treatment. Also in this case we obtained a great reduction of pain intensity in the first 3 months after the procedure. Pain intensity returned at preprocedural values after 9 months after second procedure. No complications were observed. Our experience shows pulse-dose radiofrequency is a safe, repeatable and effective technique for managing patients with symptomatic hallux valgus in the short and medium term. Pulse-dose radiofrequency may improve pain control and quality of life in patients with hallux valgus refractory to conservative therapies. © 2014 Asia Pacific League of Associations for Rheumatology and Wiley Publishing Asia Pty Ltd.

    The aim of this study was to compare the efficacy of intra-articular injections of three different agents with well known anti-inflammatory properties. Between April 2010 and January 2013 a total of 100 patients who were diagnosed as temporomandibular joint disorder in the Department of Otolaryngology at Bozok University School of Medicine were prospectively studied. Patients with symptoms of jaw pain, limited or painful jaw movement, clicking or grating within the joint, were evaluated with temporomandibular CT to investigate the presence of cartilage or capsule degeneration. In the study group there were 55 female and 45 male patients who were non-responders to conventional anti-inflammatory treatment for TMJ complaints. The patients were randomly divided into four groups consisting of a control group and three different groups who underwent intra-articular injection of one given anti-inflammatory agent for each group. We injected saline solution to intra-articular space in the control group. Of three anti-inflammatory agents including hyaluronic acid (HA, Hyalgan intra-articular injection, Sodium hyaluronate 10 mg/ml, 2 ml injection syringe, Bilim Pharmaceutical Company, Istanbul, Turkey); betamethasone (CS, Diprospan flacon, 7.0 mg betamethasone/1 ml, Schering-Plough Pharmaceutical Company, Istanbul, Turkey) and; tenoxicam (TX, Tilcotil flacon, 20 mg tenoxicam/ml, Roche Pharmaceutical Company, Istanbul, Turkey) were administered intra-articularly under, ultrasonographic guidance. Following the completion of injections the, changes in subjective symptoms were compared with visual analogue scales, (VAS) scores at 1st and 6th weeks' follow-up visits between four groups. The HA group did significantly better pain relief scores compared to the, other groups at 1st and 6th weeks (p 0.05). We found that HA produced better pain relief scores when compared to the other anti-inflammatory agents studied. The main disadvantage of HA is its relatively higher cost

    2011-10-01

    A new sensor array intended to accurately and directly measure spatial and time-dependent pressures within a highly curved biological intra-articular joint was developed and tested. To evaluate performance of the new sensor array for application within intra-articular joints generally, and specifically to fit within the relatively restrictive space of the lumbar spine facet joint, geometric constraints of length, width, thickness and sensor spatial resolution were evaluated. Additionally, the effects of sensor array curvature, frequency response, linearity, drift, hysteresis, repeatability, and total system cost were assessed. The new sensor array was approximately 0.6mm in thickness, scalable to below the nominal 12 mm wide by 15 high lumbar spine facet joint size, offered no inherent limitations on the number or spacing of the sensors with less than 1.7% cross talk with sensor immediately adjacent to one another. No difference was observed in sensor performance down to a radius of curvature of 7 mm and a 0.66±0.97% change in sensor sensitivity was observed at a radius of 5.5mm. The sensor array had less than 0.07 dB signal loss up to 5.5 Hz, linearity was 0.58±0.13% full scale (FS), drift was less than 0.2% FS at 250 s and less than 0.6% FS at 700 s, hysteresis was 0.78±0.18%. Repeatability was excellent with a coefficient of variation less than 2% at pressures between 0 and 1.000 MPa. Total system cost was relatively small as standard commercially available data acquisition systems could be utilized, with no specialized software, and individual sensors within an array can be replaced as needed. The new sensor array had small and scalable geometry and very acceptable intrinsic performance including minimal to no alteration in performance at physiologically relevant ranges of joint curvature.

    Arthroscopic ankle arthrodesis has shown high rates of union comparable to those with open arthrodesis but with substantially less postoperative morbidity, shorter operative times, less blood loss, and shorter hospital stays. To easily perform arthroscopic resection of the articular cartilage, sufficient distraction of the joint is necessary to insert the arthroscope and instruments. However, sometimes, standard noninvasive ankle distraction will not be sufficient in post-traumatic ankle arthritis, with the development of arthrofibrosis and joint contracture after severe ankle trauma. In the present report, we describe a technique to distract the ankle joint by inserting a 4.6-mm stainless steel cannula with a blunt trocar inside the joint. The cannula allowed sufficient intra-articular distraction, and, at the same time, a 4.0-mm arthroscope can be inserted through the cannula to view the joint. Screws can be inserted to fix the joint under fluoroscopic guidance without changing the patient's position or removing the noninvasive distraction device and leg holder, which are often necessary during standard arthroscopic arthrodesis with noninvasive distraction.

    Cryotherapy is commonly applied without research documenting the intra-articular (IA) temperature changes or subject discomfort between ice and a cryotherapy device. The null hypothesis is that no difference would be observed in IA temperature decline or subject tolerance between ice and the cryotherapy device in normal knees. Prospective, within-subject controlled clinical trial. Twelve subjects had IA temperature in suprapatellar pouch and skin recorded bilaterally after application of cryotherapy versus ice. Subject tolerance was recorded by 10-cm visual analog scale (VAS). Statistical evaluation was by Spearman's correlation analysis and paired, nonparametric Wilcoxon's signed rank test. Both significantly lowered (P cryotherapy) at 30 (3.3 degrees C/2.2 degrees C), 60 (12.8 degrees C/7.1 degrees C), and 90 (15.2 degrees C/9.7 degrees C) minutes. However, ice lowered the IA temperature significantly more than the cryotherapy device (P < 0.001) and was more painful by VAS at 30 and 60 minutes (P < 0.01). Both methods produced large declines in skin and IA temperatures. However, ice was more effective yet resulted in higher pain scores. The authors hypothesize that IA temperatures below a threshold are associated with increased perceived pain.

    We report a case of intra-articular intracortical chondroblastoma of the femoral condyle which radiologically appeared to be osteoid osteoma. A 19-year-old woman presented with a 3-year history of gradually increasing pain in the right knee and had been on nonsteroidal anti-inflammatory drugs for pain relief. Laboratory data were within normal limits. Radiographs showed a well-demarcated lucent lesion in the medial condyle of the right femur. A nidus-like lesion with calcifications and a sclerotic rim located in the cortex was imaged by computed tomography scan. Magnetic resonance imaging revealed bone marrow edema and soft tissue swelling around the lesion, with low signal intensity of the nidus-like lesion on both T1- and T2-weighted images. The lesion was excised en bloc and the histological diagnosis of chondroblastoma was made. A mild inflammatory reaction was observed in the bone marrow and synovium around the tumor. The chondroblastoma cells were shown to express cyclooxygenase-2 with immunohistochemistry. (orig.)

    Full Text Available Cytokine regulation possibly influences long term outcome following ankle fractures, but little is known about synovial fracture biochemistry. Eight patients with an ankle dislocation fracture were included in a prospective case series and matched with patients suffering from grade 2 osteochondritis dissecans (OCD of the ankle. All fractures needed external fixation during which joint effusions were collected. Fluid analysis was done by ELISA measuring aggrecan, bFGF, IL-1β, IGF-1, and the complement components C3a, C5a, and C5b-9. The time periods between occurrence of fracture and collection of effusion were only significantly associated with synovial aggrecan and C5b-9 levels (P<0.001. Furthermore, synovial expressions of both proteins correlated with each other (P<0.001. Although IL-1β expression was relatively low, intra-articular levels correlated with C5a (P<0.01 and serological C-reactive protein concentrations 2 days after surgery (P<0.05. Joint effusions were initially dominated by neutrophils, but the portion of monocytes constantly increased reaching 50% at day 6 after fracture (P<0.02. Whereas aggrecan and IL-1β concentrations were not different in fracture and OCD patients, bFGF, IGF-1, and all complement components were significantly higher concentrated in ankle joints with fractures (P<0.01. Complement activation and inflammatory cell infiltration characterize the joint biology following acute ankle fractures.

    We describe a case of a small intra-articular foreign body in the foot presenting 48 hours following injury, which at operation showed early evidence of septic arthritis. It is essential to accurately localise periarticular foreign bodies in the foot and proceed to arthrotomy and debridement in all cases where there is radiological or clinical evidence to suggest intra-articular retention of a foreign body.

    Full Text Available The aim of this study was to assess a novel approach to treating severe knee osteoarthritis by targeting synovial membrane, superficial articular cartilage, synovial fluid, and subchondral bone by combining intra-articular injections and intraosseous infiltrations of platelet rich plasma. We explored a new strategy consisting of intraosseous infiltrations of platelet rich plasma into the subchondral bone in combination with the conventional intra-articular injection in order to tackle several knee joint tissues simultaneously. We assessed the clinical outcomes through osteoarthritis outcome score (KOOS and the inflammatory response by quantifying mesenchymal stem cells in synovial fluid. There was a significant pain reduction in the KOOS from baseline (61.55±14.11 to week 24 (74.60±19.19, after treatment (p=0.008, in the secondary outcomes (symptoms, p=0.004; ADL, p=0.022; sport/rec., p=0.017; QOL, p=0.012, as well as VAS score (p<0.001 and Lequesne Index (p=0.008. The presence of mesenchymal stem cells in synovial fluid and colony-forming cells one week after treatment decreased substantially from 7.98±8.21 MSC/μL to 4.04±5.36 MSC/μL (p=0.019 and from 601.75±312.30 to 139.19±123.61  (p=0.012, respectively. Intra-articular injections combined with intraosseous infiltrations of platelet rich plasma reduce pain and mesenchymal stem cells in synovial fluid, besides significantly improving knee joint function in patients with severe knee osteoarthritis.

However, its oral administration often results in serious gastrointestinal adverse effects including duodenal ulceration. Thus, a novel cationic nanoparticle (NP was explored to minimize the systemic exposure and increase the retention time of PRX in the joint after intra-articular (IA injection, by forming micrometer-sized electrostatic clusters with endogenous hyaluronic acid (HA in the synovial cavity. PRX-loaded NPs consisting of poly(lactic-co-glycolic acid, Eudragit RL, and polyvinyl alcohol were constructed with the following characteristics: particle size of 220 nm, zeta potential of 11.5 mV in phosphate-buffered saline, and loading amount of 4.0% (w/w of PRX. In optical and hyperspectral observations, the cationic NPs formed more than 50 µm-sized aggregates with HA, which was larger than the intercellular gaps between synoviocytes. In an in vivo pharmacokinetic study in rats, area under the plasma concentration–time curve (AUC0–24 h and maximum plasma concentration (Cmax of PRX after IA injection of the cationic NPs were <70% (P<0.05 and 60% (P<0.05, respectively, compared to those obtained from drug solution. Moreover, the drug concentration in joint tissue 24 h after dosing with the cationic NPs was 3.2-fold (P<0.05 and 1.8-fold (P<0.05 higher than that from drug solution and neutrally charged NPs, respectively. Therefore, we recommend the IA cationic NP therapy as an effective alternative to traditional oral therapy with PRX, as it increases drug retention selectively in the joint. Keywords: piroxicam

  14. Intra-articular viscosupplementation with hylan g-f 20 to treat osteoarthritis of the knee: an evidence-based analysis.

    2005-01-01

    To assess the effectiveness and cost-effectiveness of hylan G-F 20 as a substitute for existing treatments for pain due to osteoarthritis (OA) of the knee, other viscosupplementation devices, and/or as an adjunct to conventional therapy. Hylan G-F 20 (brand name Synvisc, which is manufactured by Genzyme) is a high molecular weight derivative of hyaluronan, a component of joint synovial fluid. It acts as a lubricant and shock absorber. It is administered by injection into the joint space to treat pain associated with OA of the knee. Although the injection procedure is an insured service in Ontario, the device, hylan G-F 20, is not. Osteoarthritis is prevalent in 10% to 12% of Ontario adults, and exceeds 40% in Ontario residents aged 65 years and older. About one-half of these people have mild, moderate, or severe OA of the knee. Conventional treatment involves a combination of nonpharmacological management (e.g., weight loss, exercise, social support, and patient education), drugs, (e.g., acetaminophen, COX-2 inhibitors, nonsteroidal anti-inflammatory drugs with/without misoprostol, intra-articular glucocorticoids, opioids, and topical analgesics) and surgical interventions, such as debridement and total knee replacement, when pharmacological management fails. The growing burden of OA of the knee in the aging Ontario population combined with recent safety concerns about COX-2 inhibitors and long wait times for total joint replacement is placing pressure on the demand for new, effective technologies to manage the pain of OA. Hylan G-F 20 is derived from rooster comb hyaluronan (HA). At the time of writing, eight viscosupplement hyaluronic products are licensed in Canada. Hylan G-F 20 is distinguished from the other products by its chemical structure (i.e., cross-linked hyaluronan, hence hylan) and relatively higher molecular weight, which may bestow greater therapeutic viscoelastic properties. A complete treatment cycle of hylan G-F 20 involves an intra-articular

    Objective. To define the imaging characteristics of intra-articular tophi of the knee. Design and patients. Twelve patients with intra-articular tophi in the knee were studied with routine MR imaging, gadolinium (Gd)-enhanced MR imaging, and CT over a 4-year period. There were 11 men and one woman, 25-82 years of age (mean age 48 years). Four patients did not have a documented history of gout at the time of the MR examination. The diagnosis of intra-articular tophi was provided by arthroscopy and histological examination (5 patients), by microscopic study of joint fluid (5 patients), or by characteristic clinical, laboratory and imaging findings (2 patients). Results. In 15 MR examinations the tophi were located purely intra-articularly in 10 knees. In the remaining five MR studies, periarticular soft tissues or bone, or both, were involved. All the intra-articular tophi manifested low to intermediate signal intensity on both T1- and T2-weighted images. All five Gd-enhanced MR examinations demonstrated a heterogeneous peripheral enhancement. All 10 CT scans showed varying degrees of stippled calcifications within the tophi. The nature of the calcifications was confirmed on histological examination in three patients. Conclusion. Presenting clinical manifestations of gout may relate to intra-articular tophaceous deposits. Such deposits present as masses on MR images with low to intermediate signal intensity on both T1- and T2-weighted images and a characteristic enhancement pattern following intravenous Gd administration. These features relate primarily to internal calcifications, which are most evident on CT images. MR evaluation (including Gd administration) supplemented, in some cases, with CT scanning allows accurate diagnosis of intra-articular tophaceous deposits. (orig.)

    To compare the clinical and inflammatory joint responses to intra-articular injection of bone marrow-derived mesenchymal stem cells (MSC) including autologous, genetically modified autologous, allogeneic, or xenogeneic cells in horses. Six five-year-old Thoroughbred mares had one fetlock joint injected with Gey's balanced salt solution as the vehicle control. Each fetlock joint of each horse was subsequently injected with 15 million MSC from the described MSC groups, and were assessed for 28 days for clinical and inflammatory parameters representing synovitis, joint swelling, and pain. There were not any significant differences between autologous and genetically modified autologous MSC for synovial fluid total nucleated cell count, total protein, interleukin (IL)-6, IL-10, fetlock circumference, oedema score, pain-free range-of-motion, and soluble gene products that were detected for at least two days. Allogeneic and xenogeneic MSC produced a greater increase in peak of inflammation at 24 hours than either autologous MSC group. Genetically engineered MSC can act as vehicles to deliver gene products to the joint; further investigation into the therapeutic potential of this cell therapy is warranted. Intra-articular MSC injection resulted in a moderate acute inflammatory joint response that was greater for allogeneic and xenogeneic MSC than autologous MSC. Clinical management of this response may minimize this effect.

    Hemarthrosis after acute knee trauma is a sign of a potentially serious knee injury. Few studies have described the epidemiology and detailed injury spectrum of acute knee injuries in a general pediatric population. To document the current injury spectrum of acute knee injuries with hemarthrosis in children aged 9 to 14 years and to describe the distribution of sex, age at injury, type of activity, and activity frequency in this population. Descriptive epidemiology study. All patients in the Stockholm County area aged 9 to 14 years who suffered acute knee trauma with hemarthrosis were referred to Astrid Lindgren Children's Hospital, Karolinska University Hospital, from September 2011 to April 2012. The patients underwent clinical examination, radiography, and magnetic resonance imaging (MRI). The type of activity when injured, regular sports activity/frequency, and patient sex and age were registered. The diagnoses were classified into minor and serious injuries. The study included 117 patients (47 girls and 70 boys; mean age, 13.2 years). Seventy percent had a serious knee injury. Lateral patellar dislocations, anterior cruciate ligament ruptures, and anterior tibial spine fractures were the most common injuries, with an incidence of 0.6, 0.2, and 0.1 per 1000 children, respectively. The sex distribution was equal up to age 13 years; twice as many boys were seen at the age of 14 years. The majority of injuries occurred during sports. Forty-six patients (39%) had radiographs without a bony injury but with a serious injury confirmed on MRI. Seventy percent of the patients aged 9 to 14 years with traumatic knee hemarthrosis had a serious intra-articular injury that needed specific medical attention. Fifty-six percent of these patients had no visible injury on plain radiographs. Physicians who treat this group of patients should consider MRI to establish the diagnosis when there is no or minimal radiographic findings. The most common serious knee injury was a lateral

    Parenterally administered steroids have been shown to affect the metabolism of glucose and to cause abnormal blood glucose levels in diabetic patients. These abnormal blood glucose levels in diabetic patients raise concerns that intra-articular steroid injections also may affect blood glucose levels. We performed a systematic review of studies examining the effect of intra-articular steroid injections on blood glucose levels in patients with diabetes mellitus. A literature search of the PubMed, EMBASE, AMED, and CINAHL databases using all relevant keywords and phrases revealed 532 manuscripts. After the application of inclusion criteria, seven studies with a total of seventy-two patients were analyzed. All studies showed a rise in blood glucose levels following intra-articular steroid injection. Four of the seven studies showed a substantial increase in blood glucose. Peak values reached as high as 500 mg/dL. The peak increase in blood glucose did not occur immediately following intra-articular steroid injection, and in some cases it took several days to occur. In many patients, post-injection hyperglycemia occurred within twenty-four to seventy-two hours. Intra-articular steroid injections may cause hyperglycemia in patients with diabetes mellitus, and patients should be warned of this complication. Diabetic patients should be advised to regularly monitor their blood glucose levels for up to a week after injection and should seek medical advice if safe thresholds are breached.

    Objective: To determine the role of intra-articular corticosteroid injections in pain management during physical rehabilitation of moderate to severe cases of knee osteoarthritis. Study Design: Randomized control trial (RCT). Place and Duration of Study: Department of Rheumatology and Rehabilitation, Fauji Foundation Hospital Rawalpindi during June 2011 to February 2012. Patients and Methods: Sixty patients with moderate to severe knee osteoarthritis were randomly selected by using probability simple random sampling technique, and randomly placed into two groups A and B through flip a coin method. The intra-articular corticosteroid injections were administered into 30 patients, including 22 female and 08 male, followed by a 2 weeks physical rehabilitation program. In group B all 30 patients, 19 female and 11 male, underwent through a 2 weeks physical rehabilitation program. The visual analog scale (VAS) was used to assess the intensity of pain and was measured at the start and at completion of the 2 week treatment program. Results: There were 60 cases in the study; 30 in each treatment groups A and B, and no drop outs. Mean age of the patients in group A was 56.25 and group B it was 58.75 years. Majority of patients in both the groups were between 44 - 77 years of age. The pain intensity was calculated in group A (p-value=0.007) and group B (p-value=0.009) at baseline. The patients in group A was treated by intra-articular corticosteroid injections followed by physical rehabilitation and group B was treated only with physical rehabilitation for two months. The pain intensity was measured at the completion of treatment for group A (p - value = 0.006) and B (p - value 0.271). Conclusion: The study concluded that intra-articular corticosteroid injections combined with physical therapy management are more effective in pain management during physical rehabilitation of moderate to severe cases of knee osteoarthritis as compare with physical therapy alone.

  20. Intra-articular Nodular Fasciitis: An Unexpected Diagnosis for a Joint Lesion: A Case Report

    MF Michelle Chan

    2014-07-01

    Full Text Available Pathological lesions in and around a joint can arise from underlying dermis, subcutis, deep muscle, bone or synovium. Clinical presentation can include joint pain, joint swelling, palpable masses and mechanical restriction. Whilst giant cell tumour of tendon sheath, pigmented villonodular synovitis, synovial chondromatosis, lipoma arborescens, juxta articular myxomas and inflammatory arthritis are the better-known conditions of the joint. Intra-articular nodular fasciitis, on the other hand, is less well recognized both clinically and radiologically. It is rarely seen in routine practice and is only described in case reports in the literature. Due to the non-specific clinical and radiological findings as well as the unfamiliarity with the entity, the diagnosis of intra-articular nodular fasciitis is usually clinched only after histological examination. We present a case of intra-articular nodular fasciitis arising in the knee joint which was not suspected clinically or radiologically.

    Meniscus injury is frequently encountered in clinical practice. Current surgical therapy involving partial or complete meniscectomy relieves pain in the short-term but often leads to osteoarthritis (OA) in the long-term. In this study, we report a new strategy of articular cartilage protection by intra-articular injection of novel human meniscus stem/progenitor cells (hMeSPCs). We found that hMeSPCs displayed both mesenchymal stem cell characteristics and high expression levels of collagen II. In the rat meniscus injury model, hMeSPC transplantation not only led to more neo-tissue formation and better-defined shape but also resulted in more rounded cells and matured extracellular matrix. Stromal cell-derived factor-1 (SDF-1) enhanced the migration of hMeSPCs, whereas AMD3100 abolished the chemotactic effects of SDF-1 on hMeSPCs, both in vitro and in vivo. In an experimental OA model, transplantation of hMeSPCs effectively protected articular cartilage, as evidenced by reduced expression of OA markers such as collagen I, collagen X, and hypoxia-inducible factor 2α but increased expression of collagen II. Our study demonstrated for the first time that intra-articular injection of hMeSPCs enhanced meniscus regeneration through the SDF-1/CXCR4 axis. Our study highlights a new strategy of intra-articular injection of hMeSPCs for meniscus regeneration. PMID:24448516

    To determine the accuracy of the intra-articular location of hyaluronic acid injection using a blind approach and to establish the usefulness of fluoroscopy-guided intra-articular injection. A fluoroscopy unit was used for 368 intra-articular injections of hyaluronic acid to 93 knees in 65 patients. Initially, blind needle positioning was conducted on the fluoroscopy table. The failure rate of the blind approach among the 368 injections was evaluated, and a relationship between the Kellgren-Lawrence grade (K-L grade) and the incidence of repeated failures using the blind approach was determined for injections to 52 knees in 37 patients who received a complete cycle of injections (five consecutive injections with a one-week interval between injections). Using a blind approach, 298 of 368 trials (81.2%) resulted in a needle tip being placed in an intra-articular location, while 70 of 368 trials resulted in an extra-articular placement of the needle tip. Among 52 knees to which a complete cycle of injection (five consecutive injections with a one-week interval between injections) was administered, repeated failure of intra-articular placement using the blind approach was seen for 18 knees (34.6%); a more severe K-L grade assigned was associated with a higher rate of repeated failure. However, the trend was not statistically significant based on the Chi-squared test ({rho} value = 0.14). Fluoroscopy-guided needle placement may be helpful to ensure therapeutic intra-articular injection of the knee.

    Post-traumatic osteoarthritis (PTOA) is responsible for the majority of cases of ankle arthritis. While acute and end-stage intra-articular inflammation has previously been described, the state of the joint between fracture healing and end-stage PTOA remains undefined. This study characterized synovial fluid (SF) composition of ankles after bone healing of an intra-articular fracture to identify factors that may contribute to the development of PTOA. Of an original 21 patients whose SF was characterized acutely following intra-articular ankle fractures, 7 returned for planned hardware (syndesmotic screw) removal after bone healing (approximately 6 months) and consented to a second bilateral SF collection. SF concentrations of 15 cytokines and matrix metalloproteinases (MMPs) and 2 markers each of cartilage catabolism (CTXII and glycosaminoglycan) and hemarthrosis (biliverdin and bilirubin) were compared for previously fractured and contralateral, uninjured ankles from the same patient. Analysis was also performed to determine the effect of the number of fracture lines and involvement of soft tissue on SF composition. Interleukin (IL)-6, IL-8, MMP-1, MMP-2, and MMP-3 were significantly elevated in the SF from healed ankles compared to matched contralateral uninjured ankles at approximately 6 months after fracture. There were no differences in markers of cartilage catabolism or hemarthrosis. Only IL-1α was affected by the number of fracture lines while differences were not detected for other analytes or with respect to the involvment of soft tissue. Sustained intra-articular inflammation, even after complete bone healing, was suggested by elevations of pro-inflammatory cytokines (IL-6 and IL-8). In addition, elevated concentrations of MMPs were also noted and were consistent with a persistent inflammatory environment. This study suggests new evidence of persistent intra-articular inflammation after intra-articular ankle fracture healing and suggests potential

    Full Text Available Abstract Background Human adipose-derived mesenchymal stem cells (haMSCs have shown efficacy in treating osteoarthritis (OA both preclinically and clinically via intra-articular (IA injection. However, understanding the mode of action of the cell therapy has been limited by cell tracking capability and correlation between the pharmacokinetics of the injected cells and the intended pharmacodynamics effect. This study aims to explore methodology and to understand in vivo biodistribution of clinical-grade haMSCs labeled with fluorescent dye and injected into an immunocompetent OA rat model. Methods haMSCs labeled with fluorescent dye were investigated for their proliferation and differentiation capabilities. Labeled cells were used to establish detection threshold of a noninvasive biofluorescent imaging system before the cells (2.5 × 106 were injected into a conventional rat OA model induced by medial meniscectomy for 8 weeks. We attempted to reveal the existence of labeled cells in vivo by imaging and a molecular biomarker approach, and to correlate with the in vivo efficacy and physical presence over a follow-up period up to 10 weeks. Results In vitro proliferation and differentiation of haMSCs were not affected by the labeling of DiD dye. Detection thresholds of the labeled cells in vitro and in vivo were determined to be 104 and 105 cells, respectively. When 2.5 × 106 haMSCs were injected into the joints of a rat OA model, fluorescent signals (or >105 cells lasted for about 10 weeks in the surgical knee joint at the same time as efficacy was observed. Signals in nonsurgical rats only lasted for 4 weeks. The human MSCs were shown to engraft to the rat joint tissues and were proliferative. Human FOXP2 gene was only detected in the knee joint tissue, suggesting limited biodistribution locally to the joints. Conclusions The current study represents the first attempt to correlate cell therapy efficacy on OA with the physical presence

    Piroxicam (PRX), a potent nonsteroidal anti-inflammatory drug, is prescribed to relieve postoperative and/or chronic joint pain. However, its oral administration often results in serious gastrointestinal adverse effects including duodenal ulceration. Thus, a novel cationic nanoparticle (NP) was explored to minimize the systemic exposure and increase the retention time of PRX in the joint after intra-articular (IA) injection, by forming micrometer-sized electrostatic clusters with endogenous hyaluronic acid (HA) in the synovial cavity. PRX-loaded NPs consisting of poly(lactic- co -glycolic acid), Eudragit RL, and polyvinyl alcohol were constructed with the following characteristics: particle size of 220 nm, zeta potential of 11.5 mV in phosphate-buffered saline, and loading amount of 4.0% (w/w) of PRX. In optical and hyperspectral observations, the cationic NPs formed more than 50 μm-sized aggregates with HA, which was larger than the intercellular gaps between synoviocytes. In an in vivo pharmacokinetic study in rats, area under the plasma concentration-time curve (AUC 0-24 h ) and maximum plasma concentration ( C max ) of PRX after IA injection of the cationic NPs were <70% ( P <0.05) and 60% ( P <0.05), respectively, compared to those obtained from drug solution. Moreover, the drug concentration in joint tissue 24 h after dosing with the cationic NPs was 3.2-fold ( P <0.05) and 1.8-fold ( P <0.05) higher than that from drug solution and neutrally charged NPs, respectively. Therefore, we recommend the IA cationic NP therapy as an effective alternative to traditional oral therapy with PRX, as it increases drug retention selectively in the joint.

    Effective pain control following outpatient surgical procedures is an important aspect of patient discharge. This study was carried out with an aim to investigate the histopathological effects of intra-articular dexketoprofen trometamol injection in knee joint on synovium and cartilage in an experimental rat model. In each of 40 rats, the right knee was designated as the study group and the left knee as the control group (NS group). Under aseptic conditions, 35 rats received an injection of 0.25 ml (6.25 mg) dexketoprofen trometamol into the right knee joint and an injection of 0.25 ml 0.9 per cent normal saline solution into the left knee joint. On the 1st, 2nd, 7th, 14th, and 21st days after intra-articular injection, rats in specified groups were sacrificed by intraperitoneal injection of 120 mg/kg sodium thiopental. Knee joints were separated and sectioned for histopathological examination. Inflammatory changes in the joints were recorded according to a grade scale. No significant difference in terms of pathological changes both in synovium and cartilage was observed between the NS group and the study group on days 1, 2, 7, 14 and 21 after intra-articular injection of dexketoprofen or saline in the knee joint. The findings showed no evidence of significant histopathological damage to the cartilage and synovia for a period up to 21 days following intra-articular administration of dexketoprofen trometamol in the knee joints of rats.

    Introduction Knee osteoarthritis (OA) is a common and progressive joint disease. Treatment options for knee OA vary from simple analgesia in mild cases to knee replacement for advanced disease. Knee pain due to moderate OA can be targeted with intra-articular injections. Steroid injections have been used widely in managing acute flare-ups of the disease. In recent years, viscosupplementation has been used as a therapeutic modality for the management of knee OA. The principle of viscosupplementation is based on the physiological properties of the hyaluronic acid (HA) in the synovial joint. Despite a sound principle and promising in vitro studies, clinical studies have been less conclusive on the effectiveness of HA in managing osteoarthritic knee pain. The aim of this systematic review was to assess the effectiveness of HA intra-articular injections in the management of osteoarthritic knee pain. Methods A systematic review of the literature was performed using MEDLINE®, Embase™ and CINAHL® (Cumulative Index to Nursing and Allied Health Literature). The databases were searched for randomised controlled trials available on the effectiveness of HA intra-articular injections in managing osteoarthritic knee pain. Results The search yielded 188 studies. Of these, 14 met the eligibility criteria and were reviewed in chronological order. Conclusions HA intra-articular injections have a modest effect on early to moderate knee OA. The effect peaks at around 6–8 weeks following administration, with a doubtful effect at 6 months.

    To compare the postoperative analgesic effects of intra-articular levobupivacaine with bupivacaine following knee arthroscopy. Forty patients, aged between 20-60 years and undergoing elective knee arthroscopy were enrolled into the study protocol that was carried out in Tepecik Education and Research Hospital, Izmir, Turkey between January and June 2007. General anesthesia protocol was the same in all patients. At the end of surgery, the patients were randomly assigned into 2 groups (n=20 in each group). Group L received 20 ml 0.5% levobupivacaine and Group B received 20 ml 0.5% bupivacaine intra-articularly. We evaluated the level of postoperative pain (by visual analoque scale at 1, 2, 4, 6, 12, and 24 hours after surgery), first analgesic requirement time (period measured from the end of the surgery until further analgesia was demanded), and total analgesic consumption during 24 hours. There were no significant difference in the postoperative pain scores of the patients between groups. The first analgesic requirement times were not statistically different. Twelve patients in Group L (60%) and 9 patients in Group B (45%) needed no additional analgesic during the 24 hours (p>0.05). No complications and side effects were found related to the intra-articular treatment. The results of the study show that intra-articular 20 ml 0.5% levobupivacaine provides effective analgesia comparable to that provided by 20 ml 0.5% bupivacaine. (author)

    Intra-articular hyaluronic acid (HA) injection, known as viscosupplementation, is a widely used therapy for pain relief in knee osteoarthritis (OA). Long-term clinical efficacy of HA has been reported in spite of a relatively short residence time. Herein, we evaluated our hypothesis that intra-articular HA injection could reduce the OA-associated changes in joint afferents. OA was induced by intra-articular injection of mono-iodoacetate in rats. Animals in the OA + HA group were given three weekly intra-articular HA injections. Pain-related behaviours, including weight-bearing asymmetry and mechanical hyperalgesia of the paw, knee joint histology and immunohistochemistry of joint afferents identified by retrograde labelling, were compared between groups (naïve, OA and OA + HA). OA rats showed pain-related behaviours and up-regulation of pain-related neurochemical markers [calcitonin gene-related peptide (CGRP), tyrosine receptor kinase A (TrkA) and acid-sensing ion channel 3 (ASIC3)] in joint afferents. HA injections reduced not only the severity of OA and pain behaviours but also OA-associated neurochemical changes in joint afferents. The differences between OA and OA + HA were statistically significant in CGRP (61 ± 10% vs. 51 ± 10%; p = 0.0406) but not significant in TrkA (62 ± 10% vs. 54 ± 9%; p = 0.0878) and ASIC3 (38 ± 9% vs. 32 ± 8%; p = 0.3681). Intra-articular HA injections reduced the severity of OA, decreased mechanical hyperalgesia of the paw, but not weight-bearing asymmetry, and attenuated OA-associated up-regulation of CGRP, but not TrkA and ASIC3, in joint afferents. The modulatory effects of HA on joint afferents is one of the underlying mechanisms of the gap between HA residence time and duration of clinical efficacy. © 2014 European Pain Federation - EFIC®

    The use of triamcinolone acetonide (TA) in performance horses necessitates establishing appropriate withdrawal times prior to performance. To describe the plasma pharmacokinetics of TA and time-related urine and synovial fluid concentrations following i.m. and intra-articular administration to exercised Thoroughbred horses. Block design. Twelve racing fit adult Thoroughbred horses received a single i.m. administration of TA (0.1 mg/kg bwt). After an appropriate washout period, the same horses then received a single intra-articular TA administration (9 mg) into the right antebrachiocarpal joint. Blood, urine and synovial fluid samples were collected prior to, and at various times, up to 60 days post drug administration and analysed using liquid chromatography-mass spectrometry. Plasma data were analysed using noncompartmental analysis. Maximum measured plasma TA concentrations were 0.996 ± 0.391 at 13.2 h and 1.27 ± 0.278 ng/ml at 6.5 h for i.m. and intra-articular administration, respectively. The plasma terminal elimination half-life was 11.4 ± 6.53 and 0.78 ± 1.00 days for i.m. and intra-articular administration, respectively. Following i.m. administration, TA was below the limit of detection (LOD) by Days 52 and 60 in plasma and urine, respectively. Following intra-articular administration TA was undetectable by Day 7 in plasma and Day 8 in urine. Triamcinolone acetonide was also undetectable in any of the joints sampled following i.m. administration and remained above the limit of quantitation (LOQ) for 21 days following intra-articular administration. This study extends previous studies describing the pharmacokinetics of TA following i.m. and intra-articular administration to the horse and suggests that plasma and urine concentrations are not a good indicator of synovial fluid concentrations. Furthermore, results of this study supports an extended withdrawal time for TA given i.m. © 2013 EVJ Ltd.

    To compare clinical efficacy and complication rate as measured by postoperative falls and development of peripheral neuritis between intra-articular blockade and femoral nerve block in patients undergoing arthroscopic hip surgery. An institutional review board approved retrospective review was conducted on a consecutive series of patients who underwent elective arthroscopic hip surgery by a single surgeon, between November 2013 and April 2015. Subjects were stratified into 2 groups: patients who received a preoperative femoral nerve block for perioperative pain control, and patients who received an intra-articular "cocktail" injection postoperatively. Demographic data, perioperative pain scores, narcotic consumption, incidence of falls, and iatrogenic peripheral neuritis were collected for analysis. Postoperative data were then collected at routine clinical visits. A total of 193 patients were included in this study (65 males, 125 females). Of them, 105 patients received preoperative femoral nerve blocks and 88 patients received an intraoperative intra-articular "cocktail." There were no significant differences in patient demographics, history of chronic pain (P = .35), worker's compensation (P = .24), preoperative pain scores (P = .69), or intraoperative doses of narcotics (P = .40). Patients who received preoperative femoral nerve blocks reported decreased pain during their time in PACU (P = .0001) and on hospital discharge (P = .28); however, there were no statistically significant differences in patient-reported pain scores at postoperative weeks 1 (P = .34), 3 (P = .64), and 6 (P = .70). Administration of an intra-articular block was associated with a significant reduction in the rate of postoperative falls (P = .009) and iatrogenic peripheral neuritis (P = .0001). Preoperative femoral nerve blocks are associated with decreased immediate postoperative pain, whereas intraoperative intra-articular anesthetic injections provide effective postoperative

    The development of an allogeneic mesenchymal stem cell (MSC) product to treat equine disorders would be useful; however, there are limited in vivo safety data for horses. We hypothesized that the injection of self (autologous) and non-self (related allogeneic or allogeneic) MSC would not elicit significant alterations in physical examination, gait or synovial fluid parameters when injected into the joints of healthy horses. Sixteen healthy horses were used in this study. Group 1 consisted of foals (n = 6), group 2 consisted of their dams (n = 5) and group 3 consisted of half-siblings (n = 5) to group 1 foals. Prior to injection, MSC were phenotyped. Placentally derived MSC were injected into contralateral joints and MSC diluent was injected into a separate joint (control). An examination, including lameness evaluation and synovial fluid analysis, was performed at 0, 24, 48 and 72 h post-injection. MSC were major histocompatibility complex (MHC) I positive, MHC II negative and CD86 negative. Injection of allogeneic MSC did not elicit a systemic response. Local responses such as joint swelling or lameness were minimal and variable. Intra-articular MSC injection elicited marked inflammation within the synovial fluid (as measured by nucleated cell count, neutrophil number and total protein concentration). However, there were no significant differences between the degree and type of inflammation elicited by self and non-self-MSC. The healthy equine joint responds similarly to a single intra-articular injection of autologous and allogeneic MSC. This pre-clinical safety study is an important first step in the development of equine allogeneic stem cell therapies.

    We describe a low-cost (instrument cost) technique for joint distraction using 2 Kirschner wires and a toothed lamina spreader in lieu of a Hintermann distractor. The described technique allows for temporary intra-articular distraction and visualization and preservation of the articular surface with extra-articular instrumentation. The technique can also allow for closed reduction and percutaneous treatment in cases of soft tissue compromise. Additionally, the technique uses common orthopedic surgical instruments, leading to a minimal learning curve for novice surgeons. We have found this distraction technique to be most effective for intra-articular preparation of hindfoot and midfoot arthrodeses and for navicular fracture reduction.

    Full Text Available A 41-year-old female presented with a 3-month history of gradually worsening anterior knee pain, swelling and inability to flex the knee. Magnetic resonance imaging (MRI revealed a large intra-articular cystic swelling anterior to the anterior cruciate ligament (ACL, extending into the Hoffa's infrapatellar fat pad. Following manipulation under anaesthesia and arthroscopic debridement of the cyst, the patient's symptoms were relieved with restoration of normal knee motion. ACL ganglion cysts are uncommon intra-articular pathological entities, which are usually asymptomatic and diagnosed incidentally by MRI. This is the first reported case of an ACL cyst being so large as to cause a mechanical block to knee flexion.

This study was carried out with an aim to investigate the histopathological effects of intra-articular dexketoprofen trometamol injection in knee joint on synovium and cartilage in an experimental rat model. Methods: In each of 40 rats, the right knee was designated as the study group and the left knee as the control group (NS group. Under aseptic conditions, 35 rats received an injection of 0.25 ml (6.25 mg dexketoprofen trometamol into the right knee joint and an injection of 0.25 ml 0.9 per cent normal saline solution into the left knee joint. On the 1 st , 2 nd , 7 th , 14 th , and 21 st days after intra-articular injection, rats in specified groups were sacrificed by intraperitoneal injection of 120 mg/kg sodium thiopental. Knee joints were separated and sectioned for histopathological examination. Inflammatory changes in the joints were recorded according to a grade scale. Results: No significant difference in terms of pathological changes both in synovium and cartilage was observed between the NS group and the study group on days 1, 2, 7, 14 and 21 after intra-articular injection of dexketoprofen or saline in the knee joint. Interpretation & conclusions: The findings showed no evidence of significant histopathological damage to the cartilage and synovia for a period up to 21 days following intra-articular administration of dexketoprofen trometamol in the knee joints of rats.

    Intra-articular membranous interposition was detected by MRI in the hip joint with residual subluxation of a girl aged 5 years 10 months. This structure, which had low signal intensity on both T1- and T2-weighted images, separated the femoral head from the acetabulum. Histological examination revealed chondrometaplasia, which suggested that this interposition might be transformed to a surface cartilaginous tissue of the secondary acetabulum often observed in residual subluxation of the hip.

    Full Text Available Background: In a retrospective study we analysed intra-articular calcaneal fracture treatment by comparing results and complications related to fracture stabilization with nonlocking calcaneal plates and locking compression plates. Materials and Methods: We performed 76 osteosynthesis (67 patients of intra-articular calcaneal fractures using the standard extended lateral approach from February 2004 to October 2007. Forty-two operations using nonlocking calcaneal plates (group A were performed during the first three years, and 34 calcaneal fractures were stabilized using locking compression plates (group B in 2007. In the Sanders type IV fractures, reconstruction of the calcaneal shape was attempted. Depending on the type of late complication, we performed subtalar arthroscopy in six cases, arthroscopically assisted subtalar distraction bone block arthrodesis in six cases, and plate removal with lateral-wall decompression in five cases. The patients were evaluated by the AOFAS Ankle-Hindfoot Scale. Results: Wound healing complications were 7/42 (17% in group A and 1/34 (3% in group B. No patient had deep osseous infection or foot rebound compartment syndrome. Preoperative size of Bφhler´s angle correlated with postoperative clinical results in both groups. There were no late complications necessitating corrective procedure or arthroscopy until December 2008 in Group B. All late complications ccurred in Group A. The overall results according to the AOFAS Ankle Hindfoot Scale were good or excellent in 23/42 (55% in group A and in 30/34 (85% in group B. Conclusion: Open reduction and internal fixation of intra-articular calcaneal fractures has become a standard surgical method. Fewer complications and better results related to treatment with locking compression plates confirmed in comparison to nonlocking ones were noted for all Sanders types of intra-articular calcaneal fractures. Age and Sanders type IV fractures are not considered to be the

    The aim of the study is to retrospectively review the patients admitted and treated in the "Alexandru Rădulescu" Orthopedics and Traumatology Clinic, Cluj-Napoca for an anterior cruciate ligament tear over a 2-year period and document the intra-articular lesions found at arthroscopy as well as the treatment used for these associated lesions. The case records of 88 patients operated for anterior cruciate ligament tear over a period of 2 years were reviewed. There were 67 males and 21 females with a mean age of 28.9 years, ranging from 14 to 49 years. After recording the patient demographics, we documented all the intra-articular lesions found during knee arthroscopy, as well as all procedures undertaken concomitant with the ACL reconstruction. 50 of the 88 patients (56.8%) had associated intra-articular lesions at the time of anterior cruciate ligament reconstruction. The most common injury found was a meniscus tear, 48 patients (54.5%) had a meniscal pathology at the time of ligament reconstruction, medial meniscus being the most frequent injured one, found in 37 patients. Meniscectomy and meniscus suture were the procedures performed for these lesions, meniscectomy being more frequent. Chondral defects were the next associated injuries found with an incidence of 15.9% of the cases. The medial side of the knee was the most common site of chondral pathology. ACL tears are frequently associated with other intra-articular lesions, especially medial meniscus tears and chondral defects affecting the medial compartment. Such pathology most often needs surgical attention during the anterior cruciate ligament reconstruction.

    Controversy exists regarding the efficacy of ligament prolotherapy in alleviating sacroiliac joint pain. The inconsistent success rates reported in previous studies may be attributed to variability in patient selection and techniques between studies. It was hypothesized that intra-articular prolotherapy for patients with a positive response to diagnostic block may mitigate the drawbacks of ligament prolotherapy. The purpose of this study was to evaluate the efficacy and long-term effectiveness of intra-articular prolotherapy in relieving sacroiliac joint pain, compared with intra-articular steroid injection. This was a prospective, randomized, controlled trial. The study was conducted at an outpatient pain medicine clinic at Chonnam National University Hospital in Gwang-ju, Korea. The study included patients with sacroiliac joint pain, confirmed by ≥50% improvement in response to local anesthetic block, lasting 3 months or longer, and who failed medical treatment. The treatment involved intra-articular dextrose water prolotherapy or triamcinolone acetonide injection using fluoroscopic guidance, with a biweekly schedule and maximum of three injections. Pain and disability scores were assessed at baseline, 2 weeks, and monthly after completion of treatment. The numbers of recruited patients were 23 and 25 for the prolotherapy and steroid groups, respectively. The pain and disability scores were significantly improved from baseline in both groups at the 2-week follow-up, with no significant difference between them. The cumulative incidence of ≥50% pain relief at 15 months was 58.7% (95% confidence interval [CI] 37.9%-79.5%) in the prolotherapy group and 10.2% (95% CI 6.7%-27.1%) in the steroid group, as determined by Kaplan-Meier analysis; there was a statistically significant difference between the groups (log-rank p prolotherapy provided significant relief of sacroiliac joint pain, and its effects lasted longer than those of steroid injections.

    Full Text Available This work aimed to evaluate the analgesic efficacy of intra-articular injection of magnesium sulphate (4% compared with equivalent volume of bupivacaine (0.5% after outpatient knee arthroscopic meniscectomy. Forty patients were randomly assigned to two groups. Group M (n = 20 received intra-articular magnesium sulphate 4%, group B (n = 20 received bupivacaine (0.5%. Analgesic effect was evaluated by analgesic duration, and by measuring pain intensity at 1, 2, 4, 6, 12, 24 h both at rest and on knee movement to 90°. The primary outcome variable was pain intensity on the VAS at 1, 2, 4, 6, 12, 24 h post arthroscopy at rest and on movement (flexion of knee to 90°, although the magnesium group had lower time weighted averages (TWAs at rest and on movement, these TWAs were not statistically significant. The median duration of postoperative analgesia was significantly longer in the patients treated with magnesium sulphate (528 min than in the bupivacaine group (317 min (p < 0.0001, with less number of patients needing supplementary analgesia in magnesium group (8/20 than those of the bupivacaine group (16/20 (p < 0.022. Also analgesic consumption was significantly lower in the magnesium sulphate group (p < 0.002. We concluded that the use of magnesium sulphate is rational and effective in reducing pain, and is more physiological and shortens convalescence after outpatient arthroscopic meniscectomy, however our hypotheses that analgesic efficacy of intra-articular isotonic magnesium sulphate would be superior to intra-articular local anaesthetic cannot be supported with this study.

    Full Text Available This study was conducted to evaluate the efficacy of intra- articular injection of hyaluronic acid for the treatment of knee osteoarthritis. Patients with knee osteoarthritis were followed for a period of six months to assess the efficacy of intra-articular injection of hyaluronic acid given three times in three consecutive weeks. Fifty patients were reviewed at two, eight and 24 weeks post-injection. The average age was 60.9 years and female to male ratio was 3:1. Patients were assessed using the Lequesne Algofunctional Index for function, and the visual analogue score for pain and side effects. We found that the knee pain reduced and the function improved in most patients and these beneficial effects maintain till the last follow up. The only side effect noted was one case of acute non-septic joint effusion after the 3rd injection. We concluded that intra-articular injection of hyaluronic acid can produce pain relief and functional improvement for up to 6 months.

    Effective joint distraction is crucial in arthroscopic ankle surgery. We describe an effective and controlled intra-articular ankle distraction technique that we have studied by means of a fresh-frozen cadaver model. Using a kyphoplasty balloon, which is currently used in spine surgery, we tried to achieve a controlled distraction. After the fixation of the cadaver model, standard anteromedial and anterolateral portals were used for ankle arthroscopy. From the same portals, the kyphoplasty balloon was inserted and placed in an appropriate position intra-articularly. The necessary amount of distraction was achieved by inflating the kyphoplasty balloon with a pressure regulation pump. All anatomic sites of the ankle joint were easily visualized with the arthroscope during surgery by changing the pressure and the intra-articular position of the kyphoplasty balloon. Ankle distraction was clearly seen on the arthroscopic and image intensifier view. The kyphoplasty balloon is simple to place through the standard portals and the advantage is that it allows easy manipulation of the arthroscopic instruments from the same portal.

    Methadone hydrochloride is an opiate that has pharmacodynamic and pharmacokinetic properties that suggest it may provide longer analgesia than morphine when administered via the intra-articular route. However, no studies to date have been conducted examining the effects of intra-articular methadone hydrochloride on local tissues. Therefore, the purpose of this study was to determine the histopathologic effects of intra-articular methadone hydrochloride on local tissues in the canine knee. Nine canines, 1 to 4 years old, weighing between 20 kg and 23 kg were used. All canines had their knees randomized to receive either bupivacaine, 0.5% with epinephrine 1:200,000 (4.5 mL), and 5 mg methadone hydrochloride (0.5 mL) for the study knee, or bupivacaine, 0.5% with epinephrine 1:200,000 (4.5 mL), and 0.5 mL normal saline for the control knee. Serum methadone hydrochloride levels were obtained on all canines at 6 and 24 hours. Canines were randomly assigned to 1 of 3 groups to be euthanized at either 24 hours, 14 days, or 28 days. Following euthanization and necropsy, synovial fluid levels and tissue samples were obtained and examined for histopathologic changes. Synovial fluid samples noted a few white blood cells at 24 hours and none at 14 and 28 days. Tissue samples showed no histopathologic changes, and serum concentration levels of methadone hydrochloride were negligible.

    Full Text Available Abstract Background Intra-articular corticosteroid injection in juvenile idiopathic arthritis (JIA is often associated with anxiety and pain. Recent reports advocate the use of nitrous oxide (NO, a volatile gas with analgesic, anxiolytic and sedative properties. Objective To prospectively evaluate the effectiveness and safety of NO analgesia for intra-articular corticosteroid injection in JIA, and to assess patients and staff satisfaction with the treatment. Methods NO was administered to JIA patients scheduled for joint injection. The patient, parent, physician and nurse completed visual-analog scores (VAS (0–10 for pain, and a 5-point satisfaction scale. Change in heart rate (HR during the procedure was recorded in order to examine physiologic response to pain and stress. Patient's behavior and adverse reactions were recorded. Results 54 procedures (72 joints were performed, 41 females, 13 males; 39 Jewish, 13 Arab; mean age was 12.2 ± 4.7 year. The median VAS pain score for patients, parents, physicians and nurses was 3. The HR increased ≥ 15% in 10 patients. They had higher VAS scores as evaluated by the staff. The median satisfaction level of the parents and staff was 3.0 and 5.0 respectively. Adverse reactions were mild. Conclusion NO provides effective and safe sedation for JIA children undergoing intra-articular injections.

    The aim of this study was to describe a new magnetic resonance imaging (MRI) classification system for intra-articular soft tissue tumours based on the morphology of the lesion, with the aim to aid the differential diagnosis. We performed a retrospective review of 52 consecutive patients presenting to a specialist musculoskeletal oncology unit with a suspected intra-articular tumour. Lesions were categorised into one of four groups according to a simple classification system based on their morphological features on MRI. Distinct groupings of pathologies emerged corresponding to each of the morphological categories. Particularly when combined with radiographic features of calcification and bone erosion, certain patterns were found to be characteristic of specific diagnoses. For example multifocal, calcified lesions were found exclusively in synovial osteochondromatosis and diffuse synovitis with hypointense T2-weighted signal intensity was typical of pigmented villonodular synovitis. Certain combinations of imaging features such as diffuse solid lesions and focal lesions with bone erosion were commonly associated with malignant lesions. We suggest that by classifying intra-articular masses according to their morphological features on MRI, particularly when combined with simple radiographic features, an additional parameter may be generated to aid the radiologist in making a diagnosis. In addition, particular combinations of features provide 'red flags' to increase the index of suspicion for malignancy. (orig.)

    To determine the success rate and whether specific patient and treatment factors influenced the outcome after conservative treatment with a bar shoe with quarter clips of intra-articular fractures of the distal phalanx in horses not used for racing. Retrospective study. Thirty-two client-owned horses. Hospital records of horses that had been treated conservatively for intra-articular fractures of the distal phalanx at Skara Equine Hospital or Halland Animal Hospital in Sweden between 1995 and 2001 were reviewed. Racehorses in active training and horses affected with other musculoskeletal diseases were excluded from the study. Follow-up was performed by questionnaire and telephone inquires to the owners 1 to 7 years after injury. Twenty-two horses (69%) returned to their previous or expected level of use and did not wear their bar shoe when they were put back into training. There was no statistically significant correlation between outcome and patient or treatment variables, or bony union of the fracture. Conservative treatment of intra-articular fractures of the distal phalanx carries a fair prognosis for return to previous or expected level of use in horses not used for racing. Radiographic evidence of fracture healing and age of the patient do not seem to influence the prognosis. Horses not used for racing do not need to be shod with a bar shoe with quarter clips for the rest of their athletic career.

  18. Intra-articular pressures and joint mechanics: should we pay attention to effusion in knee osteoarthritis?

    Rutherford, Derek James

    2014-09-01

    What factors play a role to ensure a knee joint does what it should given the demands of moving through the physical environment? This paper aims to probe the hypothesis that intra-articular joint pressures, once a topic of interest, have been left aside in contemporary frameworks in which we now view knee joint function. The focus on ligamentous deficiencies and the chondrocentric view of osteoarthritis, while important, have left little attention to the consideration of other factors that can impair joint function across the lifespan. Dynamic knee stability is required during every step we take. While there is much known about the role that passive structures and muscular activation play in maintaining a healthy knee joint, this framework does not account for the role that intra-articular joint pressures may have in providing joint stability during motion and how these factors interact. Joint injuries invariably result in some form of intra-articular fluid accumulation. Ultimately, it may be how the knee mechanically responds to this fluid, of which pressure plays a significant role that provides the mechanisms for continued function. Do joint pressures provide an important foundation for maintaining knee function? This hypothesis is unique and argues that we are missing an important piece of the puzzle when attempting to understand implications that joint injury and disease have for joint function.

  19. The safety of intra-articular injections for the treatment of knee osteoarthritis: a critical narrative review.

    Science.gov (United States)

    Nguyen, Christelle; Rannou, François

    2017-08-01

    International guidelines recommend that the management of knee osteoarthritis (OA) combine both nonpharmacological and pharmacological interventions. Intra-articular (IA) therapies are considered part of this multimodal approach and are well-established Food and Drug Administration (FDA) and European Medicines Agency (EMA)-approved treatments. Areas covered: Safety data for knee OA, including IA corticosteroids, hyaluronic acid, platelet-rich plasma and botulinum toxin are critically reviewed, and evidence- and pratice-based measures to improve safety of IA therapies are discussed. Expert opinion: The incidence of AEs attributable to IA therapies across clinical trials in knee OA is very low, and barely reaches significance when compared to the incidence of AEs in the comparator group. These events are exceptionally serious. Mild differences between products have been inconsistently reported mainly for IA HA. One can distinguish self-limited AEs such as post-injection pain and swelling that are the most frequently reported AEs, from AEs that are not self-limited but rare such as septic arthritis. The safety of IA therapies can be improved by applying simple measures designed to prevent AEs. However, even though no specific safety concerns have been raised to date about IA therapies, the quality of evidence is low, and there is a need to improve the monitoring and reporting of safety data from clinical trials and post-marketing surveillance.

    The primary purpose of this review article is to discuss the role of diagnostic, corticosteroid, hyaluronic acid (HA) and platelet rich plasma (PRP) in the treatment of osteoarthritis (OA) and femoroacetabular impingement (FIA). These treatments play an important biological role in the non-operative management of these conditions. Two independent reviewers performed an search of PubMed for articles that contained at least one of the following search terms pertaining to intra-articular hip injection—local anaesthetic, diagnostic, ultrasound, fluoroscopic, image guided, corticosteroid, HA, PRP, OA, labral tears and FAI. Seventy-two full text articles were suitable for inclusion. There were 18 articles addressing the efficacy of diagnostic intra-articular hip injections. With respect to efficacy in OA there were 25 articles pertaining to efficacy of corticosteroid, 22 of HA and 4 of PRP. There were three articles addressing the efficacy of biologics in FAI. Diagnostic intra-articular hip injections are sensitive and specific for differentiating between intra-articular, extra-articular and spinal causes of hip symptoms. Ultrasound and fluoroscopy improves the precision of intra-articular positioning of diagnostic injections. Corticosteroids are more effective than HA and PRP in alleviating pain from hip OA. A higher dose of corticosteroids produces a longer benefit but volume of injection has no significant effect. Intra-articular corticosteroids do not increase infection rates of subsequent arthroplasty. There is currently limited evidence to warrant the routine use of therapeutic injections in the management of labral tears and FIA. PMID:27026814

    The goal of this study was to determine whether intra-articular administration of the potentially anti-fibrotic agent decorin influences the expression of genes involved in the fibrotic cascade, and ultimately leads to less contracture, in an animal model. A total of 18 rabbits underwent an operation on their right knees to form contractures. Six limbs in group 1 received four intra-articular injections of decorin; six limbs in group 2 received four intra-articular injections of bovine serum albumin (BSA) over eight days; six limbs in group 3 received no injections. The contracted limbs of rabbits in group 1 were biomechanically and genetically compared with the contracted limbs of rabbits in groups 2 and 3, with the use of a calibrated joint measuring device and custom microarray, respectively. There was no statistical difference in the flexion contracture angles between those limbs that received intra-articular decorin versus those that received intra-articular BSA (66° vs 69°; p = 0.41). Likewise, there was no statistical difference between those limbs that received intra-articular decorin versus those who had no injection (66° vs 72°; p = 0.27). When compared with BSA, decorin led to a statistically significant increase in the mRNA expression of 12 genes (p Cite this article: Bone Joint Res 2014;3:82-8.

    Aim: To determine reliable magnetic resonance imaging (MRI) features differentiating three paediatric intra-articular congenital or neoplastic synovial lesions that contain blood products, from post-traumatic or haemorrhagic inflammatory processes. Materials and methods: This was a retrospective review of MRI findings of 22 paediatric intra-articular congenital or neoplastic synovial lesions, including venous malformation (VM) (n = 12), pigmented villonodular synovitis (PVNS; n = 8), and synovial sarcoma (SS; n = 2). These MRI features were compared with 22 paediatric post-traumatic or inflammatory intra-articular processes containing blood products and producing mass effect. The following imaging features were assessed: presence of a discrete mass, extension, extra-articular oedema, susceptibility, joint effusion, and size. Fisher's exact test was used and results were considered statistically significant when p < 0.05. Results: The three intra-articular synovial lesions, compared with controls, were more likely to directly invade osseous structures when a discrete mass was present (13/16, 81.3% versus 1/9, 11.1%; p < 0.002) and extend into extra-articular soft tissues (13/21, 61.9% versus 2/17, 11.8%; p < 0.003), but were less likely to show extra-articular oedema (3/22, 13.6% versus 13/22, 59.1%; p < 0.004), a joint effusion (10/22,45.5% versus 19/22, 86.4%, p < 0.01), susceptibility within a joint effusion (0/22, 0% versus 11/22, 40.9%; p = 0.00), osseous oedema (3/16, 18.8% versus 7/9, 77.8%; p < 0.009), and synovial enhancement (8/21, 38.1% versus 14/16, 87.5%; p < 0.003). VMs had characteristic tubular vessels with internal fluid-fluid levels (11/12) that extended into bone (10/12) and extracapsular soft tissues (11/12). Conclusion: Our study indicates that, despite the overlapping presence of haemorrhagic products, intra-articular VM, PVNS, and SS show MRI features that permit distinction from acquired post-traumatic and haemorrhagic inflammatory

    Knee osteoarthritis (OA) is a common and often disabling joint disorder among adults that may result in impaired activity and daily function. A variety of treatment options are currently available and prescribed for knee OA depending on the severity of the disorder and physician preference. Intra-articular hyaluronic acid (IA-HA) injection is a treatment for knee OA that reportedly provides numerous biochemical and biological benefits, including shock absorption, chondroprotection, and anti-inflammatory effects within the knee. Clarity is needed as to whether the available IA-HA products should be considered for therapy as a group or whether there are significant differences in the products that need to be considered in treatment of OA of the knee. To determine whether there are differences in efficacy and safety with respect to intrinsic properties of available IA-HA injections for knee OA. Meta-analysis. A comprehensive literature search of the Medline, EMBASE, and PubMed databases was conducted for all existing randomized trials of IA-HA. The primary outcome measure analyzed was the mean pain score at the reported follow-up nearest to 26 weeks after injection. Pooled efficacy and safety results were recorded for subgroupings of HA product characteristics. A total of 68 studies were included for analysis. Products with an average molecular weight ≥3000 kDa provided favorable efficacy results when compared with products of an average molecular weight injection site than did avian-derived HA products, while high-molecular-weight products demonstrated the highest rate of injection site flare-up. Despite similarities, IA-HA products should not be treated as a group, as there are differences in IA-HA products that influence both efficacy and safety. In the available literature, IA-HA products with a molecular weight ≥3000 kDa and those derived from biological fermentation relate to superior efficacy and safety-factors that may influence selection an IA-HA product

    2018-02-01

    INTRODUCTION: In our practice Platelet Rich Plasma (PRP) injections effectively reduce pain in most but not all arthritic patients. However, for patients who fail PRP treatment, no good alternative currently exists except total joint replacement surgery. Low level laser therapy (LLLT) on the surface of the skin has not been helpful for arthritis patients in our experience. However, we hypothesized that intra-articular laser treatment would be an effective augmentation to PRP injection and would increase its efficacy in patients who had failed prior PRP injection alone. METHODS: We offered Intra-articular Low Level Laser Therapy (IAL) treatment in conjunction with repeat PRP injection to patients who had received no benefit from PRP injection alone at our center. They were the treatment group. They were not charged for PRP or IAL. They also served as a historical control group since they had all had failed PRP treatment alone. 28 patients (30 joints) accepted treatment after informed consent. 22 knees, 4 hips, 2 shoulder glenohumeral joints and 1 first carpo-metacarpal (1st CMC) joint were treated RESULTS: All patients were followed up at 1 month and no adverse events were seen from the treatment. At 6 months post treatment 46% of patients had good outcomes, and at 1 year 17% still showed improvement after treatment. 11 patients failed treatment and went on to joint replacement. DISCUSSION: A single treatment of IAL with PRP salvaged 46% of patients who had failed PRP treatment alone, allowing avoidance of surgery and good pain control.

    Full Text Available Abstract Background Up to date, no information exists about the intra-articular temperature changes of the knee related to activity and ambient temperature. Methods In 6 healthy males, a probe for intra-articular measurement was inserted into the notch of the right knee. Each subject was jogging on a treadmill in a closed room at 19°C room temperature and skiing in a ski resort at -3°C outside temperature for 60 minutes. In both conditions, temperatures were measured every fifteen minutes intra-articulary and at the skin surface of the knee. A possible influence on joint function and laxity was evaluated before and after activity. Statistical analysis of intra-articular and skin temperatures was done using nonparametric Wilcoxon's sign rank sum test and Mann-Whitney's-U-Test. Results Median intra-articular temperatures increased from 31.4°C before activity by 2.1°C, 4°C, 5.8°C and 6.1°C after 15, 30, 45 and 60 min of jogging (all p ≤ 0.05. Median intra-articular temperatures dropped from 32.2°C before activity by 0.5°C, 1.9°C, 3.6°C and 1.1°C after 15, 30, 45 and 60 min of skiing (all n.s.. After 60 minutes of skiing (jogging, the median intra-articular temperature was 19.6% (8.7% higher than the skin surface temperature at the knee. Joint function and laxity appeared not to be different before and after activity within both groups. Conclusion This study demonstrates different changes of intra-articular and skin temperatures during sports in jogging and alpine skiing and suggests that changes are related to activity and ambient temperature.

    Intra-articular physeal fractures of the distal femur are an uncommon injury pattern, with only a few small case series reported in the literature. To pool patients from 3 high-volume pediatric centers to better understand this injury pattern, to determine outcomes of surgical treatment, and to assess risk factors for complications. Case series; Level of evidence, 4. A multicenter retrospective review of all patients presenting with an intra-articular physeal fracture between 2006 and 2016 was performed. Patient demographic and injury data, surgical data, and postoperative outcomes were documented. Radiographs were evaluated for fracture classification (Salter-Harris), location, and displacement. Differences between patients with and without complications were compared by use of analysis of variance or chi-square tests. A total of 49 patients, with a mean age of 13.5 years (range, 7-17 years), met the inclusion criteria. The majority of fractures were Salter-Harris type III fractures (84%) involving the medial femoral condyle (88%). Football was responsible for 50% of the injuries. The initial diagnosis was missed in 39% of cases, and advanced imaging showed greater mean displacement (6 mm) compared with radiographs (3 mm). All patients underwent surgery and returned to sport with "good to excellent" results after 2 years. Complications were more common in patients with wide-open growth plates, patients with fractures involving the lateral femoral condyle, and patients who were casted ( P < .05). Clinicians evaluating skeletally immature athletes (particularly football players) with acute knee injuries should maintain a high index of suspicion for an intra-articular physeal fracture. These fractures are frequently missed, and advanced imaging may be required to establish the diagnosis. Leg-length discrepancies and angular deformities are not uncommon, and patients should be monitored closely. Surgical outcomes are good when fractures are identified, with high rates

    Intra-articular injection is being used widely for both diagnostic and therapeutic purposes in the hip. However, its efficacy is not always predictable in patients with hip osteoarthritis (OA). The purpose of this study was to determine whether the degree of radiographic severity of OA was predictive of the response to intra-articular injection of local anesthetic with corticosteroid and to determine the relationship between immediate pain relief resulting from the anesthetic and delayed pain relief resulting from corticosteroid administration. This retrospective study included 217 patients (220 injections) with diagnosis of hip OA who underwent a fluoroscopically guided therapeutic hip injection of local anesthetic and corticosteroid. Hip radiographs were scored using the Kellgren-Lawrence scale. Immediate and delayed pain relief was documented using a visual analog scale. Logistic regression analysis was performed to investigate whether age, gender or radiographic severity of OA were independent predictors of pain relief. Degree of agreement between immediate and delayed response was assessed with the kappa coefficient. Immediate pain relief was reported in 68.2% of hips and delayed relief in 71.4% of hips. A high level of agreement was observed between immediate and delayed pain relief (kappa = 0.80, p < 0.001). 94% of patients reporting immediate relief also reported relief 2 weeks later. Univariate and multivariate analysis revealed that neither gender nor age was related to immediate or delayed pain relief. Only severity of OA (based on radiographic analysis) was observed to be predictive of pain relief. Pain relief following intra-articular hip injection correlated with radiographic severity of OA. This intervention may be of therapeutic and prognostic value in patients awaiting hip arthroplasty. (orig.)

    Unlike with anterior cruciate ligament injury, little is known about the prevalence of intra-articular pathology associated with isolated posterior cruciate ligament (PCL) injury in the knee. The objectives of this study were to characterize and identify the frequency of meniscal tears and osteochondral injuries in these patients, and to see if management might be affected. Altogether, 48 knee MRI exams with isolated PCL tears were evaluated for the presence of: grade and location of PCL tear, meniscal tear, articular chondral lesion, bone bruise, and fracture. Comparisons between PCL tear grade and location, as well as mechanism of injury when known, with the presence of various intra-articular pathologies, were made using the chi-square or Fisher's exact test as appropriate. In all, 69 % of isolated PCL tears occur in the midsubstance, 27 % proximally. Meniscal tears were seen in 25 % of knees, involving all segments of both menisci, except for the anterior horn medial meniscus. Altogether, 23 % had focal cartilage lesions, usually affecting the central third medial femoral condyle and medial trochlea, while 12.5 % of knees had fractures, and 48 % demonstrated bone bruises, usually involving the central to anterior tibiofemoral joint. The presence of a fracture (p = 0.0123) and proximal location of PCL tear (p = 0.0016) were both associated with the hyperextension mechanism of injury. There were no statistically significant associations between PCL tear grade and presence of intra-articular abnormality. Potentially treatable meniscal tears and osteochondral injuries are relatively prevalent, and demonstrable on MRI in patients with isolated acute PCL injury of the knee. (orig.)

    To evaluate the association of preoperative intra-articular hip injection with surgical site infection after hip arthroscopy. A large administrative database was used to identify all patients undergoing hip arthroscopy from 2007 to 2015 within a single private insurer and from 2005 to 2012 within Medicare in the United States. Those that received an ipsilateral preoperative intra-articular hip injection were identified. The patients were then divided into the following groups based on the interval between preoperative injection and ipsilateral hip arthroscopy: (1) 12 months) of preoperative hip injection. Patients developing a surgical site infection within 6 months following hip arthroscopy were identified using International Classification of Diseases, Ninth Revision, and Current Procedural Terminology codes associated with infection. Groups were compared using a multivariate logistic regression analysis to control for age, gender, body mass index, smoking status, alcohol usage, and multiple medical comorbidities including diabetes mellitus, hemodialysis use, inflammatory arthritis, and peripheral vascular disease. In total, 19% of privately insured and 6% of Medicare patients received a hip injection within 12 months of hip arthroscopy. The overall infection rate in privately insured and Medicare patients was 1.19% and 1.10%, respectively. Preoperative hip injection within 3 months of surgery was associated with a significantly higher risk of postoperative infection versus controls (2.16%, odds ratio [OR] 6.1, P arthroscopy increased when preoperative intra-articular hip injections were given within 3 months of surgery.

    Full Text Available CONTEXT AND OBJECTIVE: Shoulder dislocation is the most common dislocation among the large joints. The aim here was to compare the effectiveness of reduction of acute anterior shoulder dislocation with or without articular anesthesia. DESIGN AND SETTING: Prospective randomized trial conducted in Escola Paulista de Medicina, Universidade Federal de São Paulo (EPM-Unifesp. METHODS: From March 2008 to December 2009, 42 patients with shoulder dislocation were recruited. Reductions using traction-countertraction for acute anterior shoulder dislocation with and without lidocaine articular anesthesia were compared. As the primary outcome, pain was assessed through application of a visual analogue scale before reduction, and one and five minutes after the reduction maneuver was performed. Complications were also assessed. RESULTS: Forty-two patients were included: 20 in the group without analgesia (control group and 22 in the group that received intra-articular lidocaine injection. The group that received intra-articular lidocaine had a statistically greater decrease in pain over time than shown by the control group, both in the first minute (respectively: mean 2.1 (0 to 5.0, standard deviation, SD 1.3, versus mean 4.9 (2.0 to 7.0, SD 1.5; P < 0.001 and the fifth minute (respectively: mean 1.0; 0 to 3.0; SD = 1.0 versus mean 4.0; 1.0 to 6.0; SD = 1.4; P < 0.001. There was one failure in the control group. There were no other complications in either group. CONCLUSION: Reduction of anterior shoulder dislocation using intra-articular lidocaine injection is effective, since it is safe and diminishes the pain. CLINICAL TRIAL REGISTRATION: ISRCTN27127703.

    Full Text Available Treatment of displaced intra-articular fractures of the calcaneus remains a challenge for the orthopaedic surgeon. Conservative therapy is known to produce functional impairment. Surgical approach is plagued by soft-tissue complications and insufficient fracture reduction. We describe a minimally invasive technique that will hopefully improve these issues. We want to present our first experience through two cases. The first was a 46-year-old man who presented with a Sanders type IIBC calcaneal fracture, and the second was a 86-year-old woman with a type IIIBC calcaneal fracture. We introduced 2 Schanz screws in the talus and the calcaneus. After distraction, we introduced an inflatable balloon inside the calcaneus. By inflating the balloon, the articular surface was reduced by lifting it up. Then bone cement was injected in order to maintain the reduction. Additional screw fixation was used in the young patient. Postoperative imaging showed good congruence of the subtalar joint without leakage of cement, for the two cases. After 2 months, the patients had no pain and were without soft-tissue complications. We advocate this technique to perform a minimally invasive reduction and fixation of intra-articular calcaneal fractures because it preserves soft-tissues and provides good clinical results with early weight-bearing.

    Full Text Available Intra-articular gene therapy has potential for the treatment of osteoarthritis and rheumatoid arthritis. To quantify in vitro relative gene transduction, equine chondrocytes and synovial cells were treated with adenovirus vectors (Ad, serotype 2 adeno-associated virus vectors (rAAV2, or self-complementary (sc AAV2 vectors carrying green fluorescent protein (GFP. Using 6 horses, bilateral metacarpophalangeal joints were injected with Ad, rAAV2, or scAAV2 vectors carrying GFP genes to assess the in vivo joint inflammation and neutralizing antibody (NAb titer in serum and joint fluid. In vitro, the greater transduction efficiency and sustained gene expression were achieved by scAAV2 compared to rAAV2 in equine chondrocytes and synovial cells. In vivo, AAV2 demonstrated less joint inflammation than Ad, but similar NAb titer. The scAAV2 vectors can induce superior gene transduction than rAAV2 in articular cells, and both rAAV2 and scAAV2 vectors were showed to be safer for intra-articular use than Ad vectors.

    Dextrose injection is reported to improve knee osteoarthritis (KOA)-related clinical outcomes, but its effect on articular cartilage is unknown. A chondrogenic effect of dextrose injection has been proposed. To assess biological and clinical effects of intra-articular hypertonic dextrose injections (prolotherapy) in painful KOA. Case series with blinded arthroscopic evaluation before and after treatment. Physical medicine and day surgery practice. Symptomatic KOA for at least 6 months, arthroscopy-confirmed medial compartment exposed subchondral bone, and temporary pain relief with intra-articular lidocaine injection. Four to 6 monthly 10-mL intra-articular injections with 12.5% dextrose. Visual cartilage growth assessment of 9 standardized medial condyle zones in each of 6 participants by 3 arthroscopy readers masked to pre-/postinjection status (total 54 zones evaluated per reader); biopsy of a cartilage growth area posttreatment, evaluated using hematoxylin and eosin and Safranin-O stains, quantitative polarized light microscopy, and immunohistologic cartilage typing; self-reported knee specific quality of life using the Western Ontario McMaster University Osteoarthritis Index (WOMAC, 0-100 points). Six participants (1 female and 5 male) with median age of 71 years, WOMAC composite score of 57.5 points, and a 9-year pain duration received a median of 6 dextrose injections and follow-up arthroscopy at 7.75 months (range 4.5-9.5 months). In 19 of 54 zone comparisons, all 3 readers agreed that the posttreatment zone showed cartilage growth compared with the pretreatment zone. Biopsy specimens showed metabolically active cartilage with variable cellular organization, fiber parallelism, and cartilage typing patterns consistent with fibro- and hyaline-like cartilage. Compared with baseline status, the median WOMAC score improved 13 points (P = .013). Self-limited soreness after methylene blue instillation was noted. Positive clinical and chondrogenic effects were seen

    Non-physiological stretch of the cervical facet joint's capsular ligament induces persistent behavioral hypersensitivity and spinal neuronal hyperexcitability via an intra-articular NGF-dependent mechanism. Although that ligament is innervated by nociceptors, it is unknown if a subpopulation is exclusively responsible for the behavioral and spinal neuronal responses to intra-articular NGF and/or facet joint injury. This study ablated joint afferents using the neurotoxin saporin targeted to neurons involved in either peptidergic ([Sar(9),Met (O2)(11)]-substance P-saporin (SSP-Sap)) or non-peptidergic (isolectin B4-saporin (IB4-Sap)) signaling to investigate the contributions of those neuronal populations to facet-mediated pain. SSP-Sap, but not IB4-Sap, injected into the bilateral C6/C7 facet joints 14 days prior to an intra- articular NGF injection prevents NGF-induced mechanical and thermal hypersensitivity in the forepaws. Similarly, only SSP- Sap prevents the increase in mechanical forepaw stimulation- induced firing of spinal neurons after intra-articular NGF. In addition, intra-articular SSP-Sap prevents both behavioral hypersensitivity and upregulation of NGF in the dorsal root ganglion after a facet joint distraction that normally induces pain. These findings collectively suggest that disruption of peptidergic signaling within the joint may be a potential treatment for facet pain, as well as other painful joint conditions associated with elevated NGF, such as osteoarthritis.

    To evaluate the efficacy of intra-articular hyaluronic acid (IAHA) injection for hemiplegic shoulder pain (HSP) after stroke. Thirty-one patients with HSP and limited range of motion (ROM) without spasticity of upper extremity were recruited. All subjects were randomly allocated to group A (n=15) for three weekly IAHA injection or group B (n=16) for a single intra-articular steroid (IAS) injection. All injections were administered by an expert physician until the 8th week using a posterior ultrasonography-guided approach. Shoulder joint pain was measured using the Wong-Baker Scale (WBS), while passive ROM was measured in the supine position by an expert physician. There were no significant intergroup differences in WBS or ROM at the 8th week. Improvements in forward flexion and external rotation were observed from the 4th week in the IAHA group and the 8th week in the IAS group. Subjects experienced a statistically significant improvement in pain from the 1st week in the IAS and from the 8th week in IAHA group, respectively. IAHA seems to have a less potent ability to reduce movement pain compared to steroid in the early period. However, there was no statistically significant intergroup difference in WBS and ROM improvements at the 8th week. IAHA might be a good alternative to steroid for managing HSP when the use of steroid is limited.

    Clinical practice guidelines are of increasing importance in the decision making for the treatment of knee osteoarthritis. Inconsistent recommendations regarding the use of intra-articular hyaluronic acid for the treatment of knee osteoarthritis have led to confusion among treating physicians. Literature search to identify clinical practice guidelines that provide recommendations regarding the use of intra-articular hyaluronic acid treatment for knee osteoarthritis was conducted. Included guidelines were appraised using the AGREE II instrument. Guideline development methodologies, how the results were assessed, the recommendation formation, and work group composition were summarized. Overall, 10 clinical practice guidelines were identified that met our inclusion criteria. AGREE II domain scores were variable across the included guidelines. The methodology utilized across the guidelines was heterogeneous regarding the evidence inclusion criteria, analysis of evidence results, formulation of clinical practice recommendations, and work group composition. The recommendations provided by the guidelines for intra-articular hyaluronic acid treatment for knee osteoarthritis are highly inconsistent as a result of the variability in guideline methodology. Overall, 30% of the included guidelines recommended against the use of intra-articular hyaluronic acid in the treatment of knee osteoarthritis, while 30% deemed the treatment an appropriate intervention under certain scenarios. The remaining 40% of the guidelines provided either an uncertain recommendation or no recommendation at all, based on the high variability in reviewed evidence regarding efficacy and trial quality. There is a need for a standard "appropriate methodology" that is agreed upon for osteoarthritis clinical practice guidelines in order to prevent the development of conflicting recommendations for intra-articular hyaluronic acid treatment for knee osteoarthritis, and to assure that treating physicians who

    Iliotibial band (ITB) friction syndrome is a common overuse injury typically seen in the active athlete population. A nodular lesion on the inner side of the ITB as an etiology or an accompanying lesion from friction syndrome has been rarely reported. A 45-year-old male presented with recurrent pain and a movable nodule at the lateral joint area, diagnosed as ITB friction syndrome. The nodule was confirmed as a rare intra-articular fibroma of the tendon sheath (FTS) on the basis of histopathologic findings. We describe the MRI findings, arthroscopic and pathologic features, in this case of intra-articular FTS presenting with ITB friction syndrome.

    Full Text Available BACKGROUND There are always difference of opinion in the importance of Bohler’s angle in evaluating the severity of displaced intra-articular calcaneal fractures and predicting the functional outcome following surgical fixation. The purpose of this research, the relationship exists between Bohler’s angle and the injury severity of displaced calcaneal fractures and between surgical improvement of Bohler’s angle and its practical outcome. MATERIALS AND METHODS Patients were treated surgically for unilateral closed displaced intra-articular calcaneal fractures from May 2014 to October 2016 were identified. The Bohler’s angles of bilateral calcaneus were measured and was compared to the dimension of the uninjured foot was used as its normal control. The difference in the value of Bohler’s angle measured preoperatively or after surgery between the angle of the damaged foot and that of the contralateral calcaneus was calculated, respectively. The change in Bohler’s angle by ratio was calculated by dividing the variation in the value of Bohler’s angle between bilateral calcaneus by its typical control. The injury severity was assessed according to Sanders classification. The functional outcomes were assessed using American Orthopaedic Foot and Ankle Society hindfoot scores. RESULTS 30 patients were included into the study with a mean follow-up duration of 30 months. According to Sanders classification, the fracture pattern included 12 type II, 10 type III and 8 type IV fractures. According to American Orthopaedic Foot and Ankle Society hindfoot scoring system, the excellent, good, fair and poor results were achieved in 10, 8, 4 and 2 patients, respectively. The preoperative Bohler’s angle, difference value of Bohler’s angle between bilateral calcaneus and change in Bohler’s angle by ratio each has a significant relationship with Sanders classification (P=0.003; P=0.004; P=0.005, respectively, however, is not correlated with

    Epicondylitis is the most common disease of the elbow. It is a tendinitis caused, in most cases, by repetitive motion of the forearm extensor muscles, and belongs to the group of occupational diseases that are related to work activity or sport. Intra-articular injections of glucocorticoids are often used by dermatologists, rheumatologists, orthopaedic surgeons, and primary care due to their ease of administration. However, this procedure has potential side effects. There are a limited number of case reports describing atrophy and hypopigmentation of the skin as a side effect. The general indications for glucocorticoid injections are monofocal and multifocal inflammatory disease, multifocal articular or soft tissue disease. It is more often used in more severe monofocal or multifocal inflammation, failure of drug treatment and/or rehabilitatory when other treatments are contraindicated.

    To demonstrate the clinical use of digital tomosynthesis in the depiction of labral and chondral pathology in the setting of post-operative CAM-type impingement of the hip following intra-articular administration of dilute iodinated contrast. We present images from a 46 year-old African American female with suspected CAM-type femoroacetabular impingement (FAI) following percutaneous pinning of the right hip for slipped capital femoral epiphysis (SCFE). A partial tear of the labrum and clinically significant acetabular chondral abnormalities were demonstrated with the use of digital tomosynthesis with superb anatomic detail. Digital tomosynthesis can be of great clinical utility and can depict pathology in superb anatomic detail, particularly in situations in which MRI is not available as well as under circumstances in which artifact due to orthopedic hardware is of concern as shown in this case.

    The pilon fracture is a complex injury. The purpose of this study was to evaluate the outcome of minimally invasive techniques in management of these injuries. This was a prospective study of closed AO type C2 and C3 fractures managed by early (<36 hours) minimally invasive surgical intervention and physiotherapist led rehabilitation. Thirty patients with 32 intra-articular distal tibial fractures were treated by the senior surgeon (GK). Our aim was to record the outcome and all complications with a minimum two year follow-up. There were two superficial wound infections. One patient developed a non-union which required a formal open procedure. Another patient was symptomatic from a palpable plate inferiorly. An excellent AOFAS result was obtained in 83% (20\\/24) of the patients. Early minimally invasive reduction and fixation of complex high velocity pilon fractures gave very satisfactory results at a minimum of two years follow-up.

    Fifteen patients with bilateral, symmetrical chronic pyrophosphate arthropathy of the knee were given intra-articular injections of yttrium-90 (5 mCi) plus steroid (triamcinolone hexacetonide, 20 mg) into one knee, and saline plus steroid into the other (control) knee. Allocation of the 90 Y injection was random and double blind. After 6 months there was significantly less pain, inactivity stiffness, joint-line tenderness, and effusion in the 90 Y-injected knees than in the controls (p 90 Y-injected and control knees in the changes in range of movement (p 90 Y may be of benefit in chronic pyrophosphate arthropathy, a disease for which there is no treatment. The predilection of this condition to affect the knees of the elderly makes such treatment highly suitable because the joint lends itself readily to injection and the procedure carries very few actual or potential risks in this age group.

    Tranexamic acid decreases blood loss in primary total knee arthroplasty, and no related prospective randomized clinical trials have been conducted to evaluate the effectiveness and safety of tranexamic acid in revision total knee arthroplasty. Thus, we conducted this work to evaluate the synergistic effects of intravenous plus intra-articular tranexamic acid on reducing hemoglobin loss compared with intra-articular tranexamic acid alone in revision total knee arthroplasty. This prospective, controlled study randomized 96 patients undergoing revision total knee arthroplasty into two groups: an intravenous plus intra-articular tranexamic acid group (48 patients who received 20 mg/kg intravenous tranexamic acid and 3.0 g intra-articular tranexamic acid); and an intra-articular tranexamic acid alone group (48 patients who received the same intravenous volume of normal saline and 3.0 g intra-articular tranexamic acid). The primary outcome was hemoglobin loss. Secondary outcomes included the volume of drain output, the percentage of patients who received transfusions, the number of units transfused, and thromboembolic events. The baseline data, preoperative hemoglobin, and tourniquet time were similar in both groups. There was significantly less hemoglobin loss in the intravenous plus intra-articular tranexamic acid group compared with the intra-articular tranexamic acid alone group (2.7 ± 0.6 g/dL and 3.7 ± 0.7 g/dL; p tranexamic acid alone group, the intravenous plus intra-articular tranexamic acid group also had significantly less drain output, fewer patients who received transfusions, and fewer units transfused (all p tranexamic acid alone, combined intravenous plus intra-articular tranexamic acid significantly reduced hemoglobin loss and the need for transfusion without an apparent increase in thromboembolic events in patients who underwent revision total knee arthroplasty. © 2018 AABB.

    Full Text Available Intra-articular adipose tissue deposits known as articular fat pads (AFPs are described to exist within synovial joints. Their assumed role in normal joint biomechanics is increasingly objectivized by means of advanced methods of functional imaging. AFPs possess structural similarity with body subcutaneous white adipose tissue (WAT, however, seems to be regulated by independent metabolic loops. AFP dimension are conserved during extreme WAT states: obesity, metabolic syndrome, lipodystrophy, and cachexia. Hoffa fat pad (HFP in the knee is increasingly recognized as a major player in pathological joint states such as anterior knee pain and osteoarthritis. HFP contains numerous population of mesenchymal and endothelial progenitors; however, the possible role of mature adipocytes in the maintenance of stem cell niche is unknown. We propose that AFP is an active component of the joint organ with multifunctional roles in the maintenance of joint homeostasis. Endowed with a rich network of sensitive nervous fibbers, AFPs may act as a proprioceptive organ. Adipokines and growth factors released by AFP-resident mature adipocytes could participate in the maintenance of progenitor stem cell niche as well as in local immune regulation. AFP metabolism may be locally controlled, correlated with but independent of WAT homeostasis. The identification of AFP role in normal joint turnover and its possible implication in pathological states could deliver diagnostic and therapeutic targets. Drug and/or cell therapies that restore AFP structure and function could become the next step in the design of disease modifying therapies for disabling joint conditions such as osteoarthritis and inflammatory arthritis.

    In the surgical treatment for lower-leg intra-articular fractures, the fragments have to be positioned and aligned to reconstruct the fractured bone as precisely as possible, to allow the joint to function correctly again. Standard procedures use 2D radiographs to estimate the desired reduction position of bone fragments. However, optimal correction in a 3D space requires 3D imaging. This paper introduces a new navigation system that uses pre-operative planning based on 3D CT data and intra-operative 3D guidance to virtually reduce lower-limb intra-articular fractures. Physical reduction in the fractures is then performed by our robotic system based on the virtual reduction. 3D models of bone fragments are segmented from CT scan. Fragments are pre-operatively visualized on the screen and virtually manipulated by the surgeon through a dedicated GUI to achieve the virtual reduction in the fracture. Intra-operatively, the actual position of the bone fragments is provided by an optical tracker enabling real-time 3D guidance. The motion commands for the robot connected to the bone fragment are generated, and the fracture physically reduced based on the surgeon's virtual reduction. To test the system, four femur models were fractured to obtain four different distal femur fracture types. Each one of them was subsequently reduced 20 times by a surgeon using our system. The navigation system allowed an orthopaedic surgeon to virtually reduce the fracture with a maximum residual positioning error of [Formula: see text] (translational) and [Formula: see text] (rotational). Correspondent physical reductions resulted in an accuracy of 1.03 ± 0.2 mm and [Formula: see text], when the robot reduced the fracture. Experimental outcome demonstrates the accuracy and effectiveness of the proposed navigation system, presenting a fracture reduction accuracy of about 1 mm and [Formula: see text], and meeting the clinical requirements for distal femur fracture reduction procedures.

    In this study, thirty-nine knee and three ankle effusions and pains unresponsive to the usual methods of therapy were treated by intra-articular injection of radioactive colloidal gold from November 1964 to January 1979 and followed up. Thirteen cases had classical rheumatoid arthritis: fifteen non-specific synovitis: two pigmented villonodular synovitis: one post-synovectomy, and one tuberculous arthritis. The results were as follows: 1) In eleven cases (84.6 %) of rheumatoid arthritis fourteen cases (93.3 %) of non-specific synovitis, and five cases (50.0 %) of osteoarthritis, the effusion disappeared. 2) In twelve cases (92.3 %) of rheumatoid arthritis, thirteen cases (86.7 %) of non-specific synovitis, and only two cases (20.0 %) of oseoarthritis, the pain disappeared. 3) As a whole, in thirty-three cases (78.6 %), the effusion disappeared and in twenty-eight cases (66.7 %) the pain disappeared.

    To determine if intra-articular signal changes at the sacroiliac joint space on MRI have added diagnostic value for spondyloarthritis, when compared to bone marrow edema (BME). A retrospective study was performed on the MRIs of sacroiliac joints of 363 patients, aged 16-45 years, clinically suspected of sacroiliitis. BME of the sacroiliac joints was correlated to intra-articular sacroiliac joint MR signal changes: high T1 signal, fluid signal, ankylosis and vacuum phenomenon (VP). These MRI findings were correlated with final clinical diagnosis. Sensitivity (SN), specificity (SP), likelihood ratios (LR), predictive values and post-test probabilities were calculated. BME had SN of 68.9%, SP of 74.0% and LR+ of 2.6 for diagnosis of spondyloarthritis. BME in absence of intra-articular signal changes had a lower SN and LR+ for spondyloarthritis (SN = 20.5%, LR+ 1.4). Concomitant BME and high T1 signal (SP = 97.2%, LR + = 10.5), BME and fluid signal (SP = 98.6%, LR + = 10.3) or BME and ankylosis (SP = 100%) had higher SP and LR+ for spondyloarthritis. Concomitant BME and VP had low LR+ for spondyloarthritis (SP = 91%, LR + =0.9). When BME was absent, intra-articular signal changes were less prevalent, but remained highly specific for spondyloarthritis. Our results suggest that both periarticular and intra-articular MR signal of the sacroiliac joint should be examined to determine whether an MRI is 'positive' or 'not positive' for sacroiliitis associated with spondyloarthritis.

    Mesenchymal stem cells (MSCs) therapy is a field in progress in cartilage repair strategies. We tried to investigate the functional properties of the joint and cartilage in experimental haemarthrosis (EH) after MSCs intra-articular (IA) injection. One millilitre of fresh autologous blood was injected twice a week for three consecutive weeks in three groups including control haemophilia 10 days (n = 8), control haemophilia 38 days (n = 8) and MSCs (n = 8) group. In later, 10 days after the end of IA blood injections, MSCs IA injection was performed. Eight animals received no treatment as the normal control group. Thirty-eight days after the end of IA blood injections, animals were sacrificed. Joint friction and stress-relaxation tests were done, inflammatory cytokines of synovial membrane and scanning electron microscopy of the cartilage assessed. Joint friction decreased in MSCs in comparison to other groups and was significant with normal control group, (P = 0.011). The mechanical properties of cartilage showed no significant differences between groups. Tumour necrosis factor alpha and interleukin 1 beta decreased and IL-4 very slightly increased in MSCs in comparison to the time-matched control group. Scanning electron microscopy enabled acquisition of good structural properties of the surface and layers of the cartilage after MSCs injection. The hole induced in the medial plateau of the tibia bones, after inducing haemarthrosis, were covered with cartilage-like structure. The results showed that MSCs IA injection has some beneficial effects on cartilage structure and function in haemarthrosis model and is promising in patients with haemophilia. © 2015 John Wiley & Sons Ltd.

    Purpose Knee osteoarthritis (OA) is a common disease, imposing a great burden through pain and decreased function. There are many therapeutic modalities including non-pharmacologic choices and oral, topical, and intra-articular medications. New studies have shown promising results for ozone application in knee OA. Our aim was to compare the effects of ozone therapy versus hyaluronic acid (HA) intra-articular injection in knee OA patients. Methods In this randomized clinical trial, a total of 174 patients with more than 3 months of chronic pain or swelling in the knee joints along with consistent imaging findings were enrolled and randomly allocated into two groups of HA and ozone, which were planned to undergo 3 weekly injections of HA (Hyalgan®) and 10 mL of a 30 μg/mL ozone solution, respectively. Patients were evaluated at baseline and 6 months after the last injection for pain, stiffness, and function using the visual analog scale (VAS) and the Western Ontario and McMaster Universities Arthritis Index (WOMAC) questionnaire. Results No major adverse events were detected in this study. Total WOMAC score decreased from 40.8±9.8 to 20.4±4.9 (p<0.01) in the ozone group and from 38.5±7.9 to 17.1±4.2 (p<0.01) in the HA group. A similar trend was observed in pain improvement according to VAS. Pain, stiffness, and function significantly improved in both the groups, but no between-group difference was found. Conclusion Although both ozone and HA can be effectively used for improving function and reducing pain in selected knee OA patients, neither of the two showed any superiority at 6-month follow-up.

    We used T2 mapping to quantify the effect of intra-articular hyaluronic acid administration (IAHAA) on cartilage with correlation to clinical symptoms. One hundred two patients with clinical and MRI diagnosis of hip or knee grade I-III chondropathy were prospectively included. All patients received a standard MRI examination of the affected hip/knee (one joint/patient) and T2-mapping multiecho sequence for cartilage evaluation. T2 values of all slices were averaged and used for analysis. One month after MR evaluation 72 patients (38 males; mean age 51±10 years) underwent IAHAA. As a control group, 30 subjects (15 males; 51 ± 9 years) were not treated. MR and WOMAC evaluation was performed at baseline and after 3, 9, and 15 months in all patients. T2 mapping in hyaluronic acid (HA) patients showed a significant increase in T2 relaxation times from baseline to the first time point after therapy in knees (40.7 ± 9.8 ms vs. 45.8 ± 8.6 ms) and hips (40.9 ± 9.7 ms; 45.9 ± 9.5 ms) (p evaluations, T2 relaxation dropped to values similar to the baseline ones (p T2 increase and pain reduction after IAHAA was statistically significant (r = 0.54, p T2 mapping can be used to evaluate the effect over time of IAHAA in patients with hip and knee chondropathy. • T2 relaxation times change over time after hyaluronic acid intra-articular administration • T2 relaxation times of the medial femoral condyle correlate with WOMAC variation • T2 relaxation times are different between Outerbridge I and II-III.

    ?To discuss the effectiveness of limited open reduction via sinus tarsi approach using medial distraction technique in the treatment of intra-articular calcaneus fractures by comparing with open reduction and internal fixation via extensile L-shaped incision. ?A retrospective analysis was made on the clinical data of 21 patients with intra-articular calcaneus fractures treated by sinus tarsi approach combined with medial distraction technique between April 2013 and November 2014 (minimally invasive group), and 32 patients treated by extensile L-shaped incision approach between June 2012 and September 2014 (extensile incision group). No significant difference was found in gender, age, injury pattern, fracture classification, time from injury to operation, preoperative Böhler angle, Gissane angle, calcaneal varus angle, the ankle and hind-foot score of American Orthopaedic Foot and Ankle Society (AOFAS), and visual analogue scale (VAS) score between 2 groups (P>0.05), which was comparable. The operation time, wound complications, and bone healing time were recorded. The postoperative function was also evaluated by AOFAS score and VAS score. The pre-and post-operative Böhler angle, Gissane angle, and calcaneal varus angle were measured on the X-ray films, and the corrective angle was calculated. ?Sixteen patients were followed up 6-18 months (mean, 11.5 months) in the minimally invasive group, and 23 patients for 6-24 months (mean, 13.5 months) in the extensile incision group. Difference was not significant in operation time between 2 groups (t=0.929, P=0.796). No complication occurred in the minimally invasive group; partial skin flap necrosis occurred in 3 cases of the extensile incision group, was cured after dressing change. There was no loosening of implants or reduction loss in 2 groups at last follow-up. Subtalar joint stiffness occurred in 1 case of the minimally invasive group and 4 cases of the extensile incision group, and 1 patient had discomfort for the

    The increasing demand for total knee arthroplasty (TKR) and the initiatives to reduce health care spending have put the responsibility for efficient care on hospitals and providers. Multidisciplinary care pathways have been shown to shorten length of stay and result in improved short-term outcomes. However, common problems such as post-op nausea, orthostasis, and quad weakness remain, while reliance on discharge to rehabilitation facilities may also prolong hospital stay. Our aim was to document that combined modifications of our traditional clinical pathway for unilateral TKR could lead to improved short-term outcomes. We pose the following research questions. Can pathway modifications which include intra-articular infusion and saphenous nerve block (SNB) provide adequate pain relief and eliminate common side effects promoting earlier mobilization? Can planning for discharge to home avoid in-patient rehab stays? Can these combined modifications decrease length of stay even in patients with complex comorbidities indicated by higher ASA class? Will discharge to home incur an increase in complications or a failure to achieve knee range of motion? A retrospective review was performed and identified two cohorts. Group A included 116 patients that underwent unilateral TKR for osteoarthritis between August 2009 and August 2010. Group B included 171 patients that underwent unilateral TKR for osteoarthritis between February 2012 to February 2013. Group A patients were treated with spinal anesthesia with patient-controlled epidural analgesia (PCEA)/femoral nerve block (FNB) for the first 48 h after surgery. Discharge planning was initiated after admission. Group B had spinal anesthesia with SNB and received a continuous intra-articular infusion of 0.2% ropivicaine for 48 h post-op. Discharge planning was initiated with a case manager prior to hospitalization and discharge to home was declared the preferred approach. An intensive home PT program was made available through

    The aim of this study was to generate and characterize a chondroitin sulfate-cysteine conjugate (CS-cys) as a novel bioadhesive agent for intra-articular use. Mucoadhesive properties of synthesized CS-cys were investigated by rheological measurement of polymer-mucus mixture and rotating cylinder method, while bioadhesive features of CS-cys on porcine articular cartilage were evaluated via tensile studies. Thiolation was achieved by attachment of l-cysteine to CS via amide bond formation mediated by carbodiimide as a coupling reagent. The conjugate exhibited 421.17±35.14 μmol free thiol groups per gram polymer. The reduced CS-cys displayed 675.09±39.67 μmol free thiol groups per gram polymer after disulfide bonds reduction using tris(2-carboxyethyl)phosphine hydrochloride. The increase in dynamic viscosity of thiolated CS due to oxidative disulfide bond formation was demonstrated using capillary viscometer. The combination of CS-cys and mucus led to 4.57-fold increase in dynamic viscosity in comparison with mucus control. Furthermore, adhesion time to porcine mucosa of CS-cys-based test disk was enhanced by 2.48-fold compared to unmodified CS as measured by rotating cylinder method suggesting the interaction between thiomers and mucus gel layer via disulfide bonds formation. Tensile studies of thiolated CS on porcine articular cartilage showed 5.37- and 1.76-fold increase in the total work of adhesion and the maximum detachment force, respectively, in comparison with unmodified CS indicating bioadhesive features of CS-cys. Cytotoxicity of CS-cys was assessed in Caco-2 cells and rat primary articular chondrocytes using MTT and LDH release assay, thereby showing the safety of CS-cys at a concentration of 0.25% (w/v) in Caco-2 cells. Furthermore, 0.1% of CS-cys was found non-toxic to rat primary articular chondrocytes. According to these results, CS-cys provides improved bioadhesive properties that might be useful as an intra-articular agent for treatment of

    For a fracture classification to be useful it must provide prognostic significance, interobserver reliability, and intraobserver reproducibility. Most studies have found reliability and reproducibility to be poor for fracture classification schemes. The purpose of this study was to evaluate the interobserver and intraobserver reliability of the Sanders and Crosby-Fitzgibbons classification systems, two commonly used methods for classifying intra-articular calcaneal fractures. Twenty-five CT scans of intra-articular calcaneal fractures occurring at one trauma center were reviewed. The CT images were presented to eight observers (two orthopaedic surgery chief residents, two foot and ankle fellows, two fellowship-trained orthopaedic trauma surgeons, and two fellowship-trained foot and ankle surgeons) on two separate occasions 8 weeks apart. On each viewing, observers were asked to classify the fractures according to both the Sanders and Crosby-Fitzgibbons systems. Interobserver reliability and intraobserver reproducibility were assessed with computer-generated kappa statistics (SAS software; SAS Institute Inc., Cary, North Carolina). Total unanimity (eight of eight observers assigned the same fracture classification) was achieved only 24% (six of 25) of the time with the Sanders system and 36% (nine of 25) of the time with the Crosby-Fitzgibbons scheme. Interobserver reliability for the Sanders classification method reached a moderate (kappa = 0.48, 0.50) level of agreement, when the subclasses were included. The agreement level increased but remained in the moderate (kappa = 0.55, 0.55) range when the subclasses were excluded. Interobserver agreement reached a substantial (kappa = 0.63, 0.63) level with the Crosby-Fitzgibbons system. Intraobserver reproducibility was better for both schemes. The Sanders system with subclasses included reached moderate (kappa = 0.57) agreement, while ignoring the subclasses brought agreement into the substantial (kappa = 0.77) range

    Tibial plateau fractures occur frequently while participating in winter sports, but there is no information on whether skiers can resume sports and recreational activities after internal fixation of these fractures. Skiers can resume low-impact sports activity after internal fixation of tibial plateau fractures. Case series; Level of evidence, 4. A total of 103 patients were surveyed by postal questionnaires to determine their sports activities at a mean of 7.8 ± 1.8 years after internal fixation of intra-articular tibial plateau fractures. The survey also included the Lysholm score, the Tegner activity scale, and a visual analog scale (VAS) for pain. At the time of the survey, 88% of the patients were engaged in sports activities (rate of return to sports, 88%), and 53% continued to participate in downhill skiing. The median number of different activities declined from 5 (range, 1-17) preoperatively to 4 (range, 0-11) postoperatively (P Sports frequency and duration per week did not change: 3 (range, 1-7) preoperatively versus 3 (range, 0-7) postoperatively (P = .275) and 4 hours (range, 1-16 hours) preoperatively versus 3.5 hours (range, 0-15 hours) postoperatively (P = .217), respectively. Median values of all outcome scores declined: Lysholm score, 100 (range, 85-100) preoperatively versus 94.5 (range, 37-100) postoperatively (P sports at the time of follow-up compared with the ability before the accident was rated as "similar" by 57 patients (62.0%) and as "worse" by 35 patients (38.0%). The more severe fracture types, B3 and C3 according to the AO classification system, were associated with poorer outcomes related to return to sports and functional scores. A large percentage of skiers with surgically treated intra-articular tibial plateau fractures cannot continue to participate in downhill skiing; however, the majority could resume an active lifestyle for several years after the trauma. Fracture type seems to be an important factor influencing physical

    The objective of this study was to evaluate intra-articular dextrose prolotherapy for osteoarthritis of the elbow or stifle in dogs in a randomized, double-blind, placebo-controlled, prospective pilot study. Seventeen dogs were evaluated with 10 meeting inclusion criteria for this study. Evaluations included orthopedic exam, visual lameness scoring, Canine Brief Pain Inventory (CBPI), goniometry, kinetic gait analysis, and radiography. Initial lameness score, age, body weight, duration of lameness, and CBPI scores did not differ between groups. Change in CBPI pain severity score in the prolotherapy group from wk 6-12 was significantly less improved than in the placebo group, with no other significant differences in pain severity or pain interference scores between groups. Range of motion and radiographic scores did not differ between groups at any time. Mean kinetic forces improved in prolotherapy dogs but were not significantly different between treatment groups at any time. Although easily performed and well-tolerated, there were no statistically significant benefits of dextrose prolotherapy for treatment of osteoarthritis of the elbow and stifle in dogs. Post hoc power analysis of these sample means and standard deviations found that 29-106 animals per group would be necessary to demonstrate significant differences in kinetic forces, providing useful guidance for future studies.

    Intra-articular (IA) injection of hyaluronic acid (HA) into the hip joint appears to be safe and well tolerated but only a small number of randomized clinical trials in humans has been published. The objective of this prospective study was to evaluate the efficacy and safety of a single IA injection of high-molecular-weight (2800 kDa) HA (Coxarthrum) for hip osteoarthritis. All patients received a single IA administration of 2.5 % sodium hyaluronate (75 mg/3 mL) of high molecular weight. Fluoroscopy requires an iodized contrast medium (iopamidol, 1 ml) which highlights the capsule before administering HA. Patients were evaluated before IA injection (T0), after 3 months, after 6 months and after 1 year from injection. Results were evaluated by the Brief Pain Inventory (BPI II), Harris Hip Score and a visual analog scale of pain (pain VAS). All treated patients were considered for statistical analysis. Two hundred seven patients were included at T0. The mean age was 67 years (range 46-81). Regarding BPI severity score, changes in pain between T0 and the three following visits were statistically highly significant (p injection of Coxarthrum is effective from the third month and that the results are stable or continue to improve up to 1 year.

    One hundred and eleven patients who had seropositive rheumatoid arthritis and persistent synovitis of the knee were treated with intra-articular injection of 270 millicuries of dysprosium-165 bound to ferric hydroxide macroaggregates. A two-year follow-up was available for fifty-nine of the treated knees. Thirty-nine had a good result; nine, a fair result; and eleven, a poor result. Of the twenty-five knees that had Stage-I radiographic changes, nineteen had a good result. Of the thirty-four knees that had Stage-II radiographic changes, twenty showed a good result. Systemic spread of the radioactivity from the injected joint was minimum. The mean whole-body dose was calculated to be 0.3 rad and that to the liver twenty-four hours after injection, 3.2 rads. The results indicated that dysprosium-165-ferric hydroxide macroaggregate is an effective agent for performing radiation synovectomy, particularly in knees that have Stage-I radiographic changes. Because of the minimum rate of systemic spread of the dysprosium-165, it offers a definite advantage over agents that previously have been used

    Full Text Available Osteoid osteoma of the calcaneus is rare and frequently misdiagnosed as arthritis because of similar symptoms. In addition, radiographic findings may be nonspecific, and magnetic resonance imaging (MRI may show a bone marrow edema and changes in adjacent soft tissue. A 19-year-old man presented with a 6-month history of persistent pain and swelling in the left hind foot; diagnostic computed tomography and MRI analyses revealed lesions suggesting an intra-articular osteoid osteoma of the calcaneus. Initial MRI did not show specific findings. On operation, the tumor was removed by curettage; pathologic findings demonstrated woven bone trabeculae surrounded by connective tissue, confirming the diagnosis. To the best of our knowledge, MRI scans in all cases of calcaneal osteoid osteoma reported till 3 months after the injury exhibited a nidus. We believe that calcaneal osteoid osteoma should be considered as a differential diagnosis in patients undergoing MRI 3 months after symptom presentation; early computed tomography is critical in diagnosis.

    Nano scale wear particles would generate from orthopedic implants with nano scale surface topography because of residual stress. In this study, the effect of TiO 2 nanoparticles on articular cartilage was investigated by intra-articular injection in rats. Using contrast-enhanced high-resolution micro computed tomography (micro-CT) technology, the decreased thickness of articular cartilage in distal femur was determined at 1, 7, 14, and 30 days after nanoparticle exposure. A strong linear correlation (r=0.928, P 2 nanoparticles, cartilage thickness showed time-dependent decrease, and cartilage volume was decreased too. Further, the histopathological examination showed the edema chondrocyte and shrinked nucleus in the radial and calcified zone of cartilage. The ultrastructure of articular cartilage implied that the chondrocytes was degenerated, expressing as the condensed chromatin, the dilated endoplasmic reticulum, and the rich mitochondria. Even, the fragments of ruptured endoplasmic reticulum were observed in the cytoplasm of chondrocytes at postexposure day 30. Results indicate that potential damage of articular cartilage was induced by particles existed in knee joint and imply that the bio monitoring should be strengthened in patients with prostheses replacement.

    Thirty-six patients with intra-articular displaced calcaneal fractures were examined to determine both physician- and patient-based outcomes. Three groups were selected. Group A was treated with open reduction and internal fixation, group B was treated with open reduction internal fixation and supplemental bone graft augmentation and the patients in group C were treated with plaster cast immobilisation and no formal operative treatment. All cohorts were well matched for age, sex and severity of injury. Patients were evaluated using both the American Foot and Ankle Society Scoring System (AFASS) and the short form 36 (SF-36). Minimum time to follow up was 4 years. No significant difference was observed between the three groups with regards to pain and functional outcomes using the AFASS score (P>0.05). No difference was observed between the three groups using the SF-36 score (P>0.1). A statistically significant difference was observed, using radiological criteria, between both groups A and B when compared to the non-operative group C. The rate of wound infection in groups A and B was 31.5%. No correlation was found between the SF-36 score and the AFASS score. No correlation was found between the radiological score and either the SF-36 or the AFASS score. This study has found that the conservative treatment of calcaneal fractures can produce satisfactory outcomes with lower morbidity than surgically treated fractures.

    The purpose of this study was to investigate and validate the accuracy and safety of a technique using an anterior approach for non-image-guided intra-articular injection of the hip by use of anatomic landmarks. We enrolled 55 patients. Injections were performed before supine hip arthroscopy after landmarking and before application of traction. After the needle insertion, success was confirmed with an air arthrogram and by direct visualization after arthroscope insertion. Accuracy and difficulty achieving correct needle placement were correlated with age, weight, height, body mass index, body type, gender, and surgical indication, as well as femoral and pelvic morphology. Forty-five patients who underwent injection in the office were followed up separately to document injection side effects. Needle placement accuracy was correlated to patients' demographics. All statistical tests with P values were 2 sided, with the level of significance set at P injections by use of the direct anterior approach, from the intersection of the lines drawn from the anterior superior iliac spine and 1 cm distal to the tip of the greater trochanter, are safe and reproducible. Patient characteristics, such as increased subcutaneous adipose tissue or osseous anatomic variants, can lead to difficulty in placing the needle successfully. These characteristics can be predicted with the aid of physical examination and careful study of the pelvic radiographs. Level IV, therapeutic case series.

    An intra-articular injection of platelet-rich plasma (PRP) may be an effective treatment for osteoarthritis (OA). However, its efficacy in ankle OA has not been investigated yet. The purpose of this study was to assess the safety and efficacy of an intra-articular injection of PRP in patients with ankle OA during a 24-week period. Twenty ankles of 20 patients with varus-type ankle OA who received intra-articular injections of PRP were evaluated. PRP was extracted from whole blood by using the double-spin technique. Three injections of 2-mL PRP were administered to the ankle at an interval of 2 weeks under ultrasonographic guidance. Adverse events and efficacy were assessed at 4, 12, and 24 weeks after the last injection. Clinical outcomes were assessed by using the visual analog scale (VAS) for pain, the Japanese Society for Surgery of the Foot (JSSF) ankle/hindfoot scale, and the Self-Administered Foot Evaluation Questionnaire (SAFE-Q). No serious adverse effects were observed during the follow-up period. The VAS and JSSF scale scores significantly decreased from baseline to 4, 12, and 24 weeks after treatment ( P SAFE-Q significantly improved from baseline to 12 weeks after treatment ( P = .04). Overall, the amount of pain reduction was maximal at 12 weeks after the last injection, and the effect was reduced at 24 weeks. The patients with late-stage OA had worse scores in all outcomes than those with early-stage OA. Intra-articular injections of PRP resulted in no serious adverse effects and significantly reduced pain in the patients with ankle OA. PRP treatment can be safe and effective and may be an option in the treatment of ankle OA. Level IV, case series.

    Deep infection is a debilitating complication after shoulder arthroplasty. Intra-articular injection of antibiotic can give a higher concentration compared with intravenous administration. We hypothesized that a group of patients given an intra-articular, intraoperative injection of gentamicin would report a lower infection rate than a group without local antibiotics. Between 2005 and 2011, the senior author performed 507 shoulder arthroplasties. We retrospectively reviewed all of those cases. All patients were administered systemic prophylactic antibiotics. Beginning in June 2007, patients were also injected with 160 mg of gentamicin in the glenohumeral joint at the end of their surgery. Patient records were examined for preexisting medical conditions, type of surgery, and presence of infection. Patients receiving surgery before 2007 were compared with those after to determine the effect of prophylactic gentamicin administration in preventing deep infection associated with surgery. All patients were observed for a minimum of 1 year. Of the 507 surgeries, 164 were performed before 2007 (without intra-articular injection of gentamicin; group A) and 343 were performed with addition of gentamicin (group B). In group A, 5 patients presented with infection (3.0%) compared with 1 in group B (0.29%). The gender, mean age, mean body mass index, and prevalence of comorbidities were similar between the groups. The data from this study support the conclusion that intra-articular intraoperative gentamicin administration may reduce postoperative infection.

    Medial epicondyle entrapment after an acute fracture dislocation of the elbow is a common finding in the pediatric population, but a rare finding in adults. We present a case of an adult patient diagnosed with a traumatic fracture dislocation of the elbow joint with intra-articular entrapment of the medial epicondyle. After initial evaluation, closed reduction was done. Stability testing after reduction showed an unstable joint; thus, open reduction and internal fixation was decided. PMID:29666736

    The present study examined the analgesic effects of slow-releasing bupivacaine from hydrogel on chronic arthritic pain in rats. Osteoarthritis (OA) was induced by monosodium iodoacetate (MIA) injection into the right knee joint. Hydrogel (HG: 20, 30, and 50 μL) and temperature-sensitive hydrogel containing bupivacaine (T-gel: 20, 30, and 50 μL) were injected intra-articularly 14 days after MIA injection. Behavioral tests were conducted. The rats showed a significant decrease in weight load and paw withdrawal threshold (PWT). Intra-articular 0.5% bupivacaine (10 and 20 μL) significantly reversed MIA-induced decreased PWT, with no effect on weight load. In normal rats, hydrogel did not produce significant changes in PWT but at 30 and 50 μL slightly decreased weight bearing; T-gel did not cause any changes in both the weight load and PWT. In OA rats, T-gel at 20 μL had a significant analgesic effect for 2 days, even though T-gel at 50 μL further reduced the weight load, demonstrating that intra-articular T-gel (20 μL) has long-lasting analgesic effects in OA rats. Thus, T-gel designed to deliver analgesics into the joint cavity could be an effective therapeutic tool in the clinical setting. PMID:26881207

    Treatment of intra-articular fractures of the mandibular condyle head is conservative at most institutions dealing with facial fractures. Recently, reports had been published about benefits of surgical treatment in these fractures. From July 2004 until the end of June 2006, 13 patients with 16 displaced intra-articular fractures of the mandibular condyle were treated with open reduction and internal fixation at the Department of Oral and Maxillofacial Surgery in Ljubljana, Slovenia, using the preauricular approach and the lag screw technique. Twelve of the 13 patients could open their mouths for 40 mm or more, and 10 had a deflection of the chin of less than 2 mm upon maximal opening. None of the patients experienced pain upon rest, palpation, or chewing. Occlusion was not noted as altered in any of the cases, neither subjectively, nor on examination. There were no cases of postoperative weakness of the temporal branch of the facial nerve. Surgical treatment of intra-articular condyle fractures using the preauricular approach achieves a good exposure and enables proper reduction. Stable fixation of fractured bony fragments can be achieved using the lag screw technique. Another benefit of open exposure is revision and repair of TMJ soft tissues. With the appropriate surgical technique, the surgical procedure is safe and leads to good results.

    Abstract: The optimum anaesthetic and analgesic management following hip arthroscopy is yet to be determined. There is, in addition, some concern over the use of intraarticular local anaesthetic. We compared the analgesic efficacy of intra-articular infiltration compared with portal infiltration of bupivacaine following hip arthroscopy. Patients were randomised to receive either 10ml of 0.25% bupivacaine either into the joint or around the portal sites following completion of surgery. 73 patients were recruited (40 intra-articular). The portal infiltration group required significantly more rescue analgesia immediately after surgery (2.33mg vs.0.57mg, p=0.036). Visual Analogue Scale pain scores were not significantly different at 1 and 2 hours following surgery, but at 6 hours the portal group had significantly lower VAS scores (p=0.0036). We believe that the initial pain following surgery results from capsular injury and this explains the need for more rescue analgesia in the portal infiltration group. Further work is needed to establish the ideal regimen. A combination of portal and intra-articular infiltration may be the most efficacious.

    Full Text Available Background & Objectives: Acute anterior shoulder dislocation needs prompt reduction of the dislocation. The ideal reduction method should be simple, fast, effective and non- traumatic, with minimal pain, and should not cause further injury to the affected shoulder. Intra-articular local lignocaine injection is a means of achieving analgesia with less complication, and allowing prompt patient discharge of patient after reduction. The study was conducted with objective to evaluate the effectiveness of intra-articular lignocaine for reduction of acute anterior shoulder dislocation.Materials & Methods: Twenty- one cases of acute anterior shoulder dislocation were reduced using intra-articular local lignocaine injection as a method of analgesia by modified Hippocrates method.Results: The mean age was 44.71 years ± SD 20.14 while 11 cases were reduced with one to six hours of injury. Pain assessed through application of a visual analogue scale during the maneuver revealed scores ranging from two to eight with mean score of 4.29 ± SD 1.55.Conclusion: This method is not only safe and effective but also reduces hospital stay and has negligible adverse effects making it a popular choice for most orthopedists.

    The use of corticosteroids, such as betamethasone, in performance horses is tightly regulated. The objective of the current study was to describe the plasma pharmacokinetics of betamethasone as well as time-related urine and synovial fluid concentrations following intra-articular administration to horses. Twelve racing-fit adult Thoroughbred horses received a single intra-articular administration (9 mg) of a betamethasone sodium phosphate and betamethasone acetate injectable suspension into the right antebrachiocarpal joint. Blood, urine, and synovial fluid samples were collected prior to and at various times up to 21 days post drug administration. All samples were analyzed using tandem liquid chromatography-mass spectrometry. Plasma data were analyzed using compartmental pharmacokinetic modeling. Maximum measured plasma betamethasone concentrations were 3.97 ± 0.23 ng/mL at 1.45 ± 0.20 h. The plasma elimination half-life was 7.48 ± 0.39 h. Betamethasone concentrations were below the limit of detection in all horses by 96 h and 7 days in plasma and urine, respectively. Betamethasone fell below the limit of detection in the right antebrachiocarpal joint between 14 and 21 days. Results of this study provide information that can be used to regulate the use of intra-articular betamethasone in the horse. Copyright © 2017 John Wiley & Sons, Ltd.

A randomized observational non-interventional non-placebo controlled trial was conducted. It included 18 patients who were randomized to 2 groups with 9 in each. One patient group took only ASU along with nonsteroidal anti-nflammatory drugs (NSAIDs; the other received ASU in combination with intra-articular hyaluronic acid. Their treatment was performed for 6 months, followed by a 6-month follow-up. The results were assessed by the WOMAC index. Account was taken of the opinions of a patient and his / her physician on therapeutic effectiveness, as well as altered needs for NSAIDs during treatment and after the follow-up.Results. There was a gradual reduction in joint pain, stiffness, and dysfunction (as shown by the visual analog scale in both groups just one month posttherapy. This trend remained for 3 months. After 6 months of therapy, there were slight increases in the values of joint pain, stiffness, and dysfunction in the combined therapy group whereas the values continued to decrease in the monotherapy group. Six months after termination of treatment, the examined values doubled in the ASU monotherapy group and remained at posttreatment visit levels in the combined therapy group. Just the same, six months after termination of 6-month therapy, both groups displayed the significantly lower values of pain, stiffness, and dysfunction than those prior to treatment. ASU used both alone and in combination with hyaluronic acid was noted to be well tolerated. The considerable reduction in the needs for NSAIDs in both groups and, in a number of cases, the possibility of reducing their intake proved the efficiency of ASU used alone and in combination with hyaluronic acid.

    The intra-articular (IA) application of pulsed radiofrequency (PRF) for pain in small and large joints represents a recent development that has proven to be effective in many cases. We performed a retrospective study of 89 such procedures in 57 consecutive patients with chronic articular pain. The aim of this retrospective study is to evaluate the effectiveness of intraarticular PRF in a group of 57 consecutive patients with chronic joint pain. Patients with intractable joint pain for more than 6 months were treated with IA PRF 40-45V for 10-15 min in small joints and 60V for 15 min in large joints using fluoroscopic confirmation of correct needle position. A total of 28 shoulders, 40 knees, 10 trapezio-metacarpal, and 11 first metatarso-phalangeal joints were treated. Results were evaluated at 1, 2, and 5 months. The procedure was repeated after 1 month in 10 patients with initial suboptimal results. Success was defined as a reduction of pain score by at least 50%. All groups showed significant reductions in pain scores at all three follow-up visits. Success rates were higher in small joints (90% and 82%, respectively) than large ones (64% and 60%, respectively). Interestingly, IA PRF was successful in 6 out of 10 patients who had undergone previous surgery, including 3 with prosthetic joint replacement and in 6 of the 10 repeated procedures. There were no significant adverse effects or complications. IA PRF induced significant pain relief of long duration in a majority of our patients with joint pain. The exact mechanism is unclear, but may be related to the exposure of immune cells to low-strength RF fields, inducing an anti-inflammatory effect. The success rate appears to be highest in small joints. We recommend additional research including control groups to further investigate and clarify this method; our data suggest that it may represent a useful modality in the treatment of arthrogenic pain.

    INTRODUCTION: Although regularly ignored, there is growing evidence that posterior tibial plateau fractures affect the functional outcome. The goal of this study was to assess the incidence of posterior column fractures and its impact on functional outcome and general health status. We aimed to identify all clinical variables that influence the outcome and improve insights in the treatment strategies. A retrospective cohort study including 218 intra-articular tibial plateau fractures was conducted. All fractures were reclassified and applied treatment was assessed according to the updated three-column concept. Relevant demographic and clinical variables were studied. The patient reported outcome was assessed using the Knee injury and Osteoarthritis Outcome Score (KOOS). Median follow-up was 45.5 (IQR 24.9-66.2) months. Significant outcome differences between operatively and non-operatively treated patients were found for all KOOS subscales. The incidence of posterior column fractures was 61.9%. Posterior column fractures, sagittal malalignment and an increased complication rate were associated with poor outcome. Patients treated according to the updated three-column concept, showed significantly better outcome scores than those patients who were not. We could not demonstrate the advantage of posterior column fracture fixation, due to a limited patient size. Our data indicates that implementation of the updated three-column classification concept may improve the surgical outcome of tibial plateau fractures. Failure to recognize posterior column fractures may lead to inappropriate utilization of treatment techniques. The current concept allows us to further substantiate the importance of reduction and fixation of posterior column fractures with restoration of the sagittal alignment. 3.

    There are several published computed tomography (CT) classification systems for calcaneus fractures, each validated by a different standard. The goal of this study was to measure which system would best predict clinical outcomes as measured by a widely used and validated musculoskeletal health status questionnaire. Forty-nine patients with isolated intra-articular joint depression calcaneus fractures more than 2 years after treatment were identified. All had preoperative CT studies and were treated with open reduction and plate fixation using a lateral extensile approach. Four different blinded reviewers classified injuries according to the CT classification systems of Crosby and Fitzgibbons, Eastwood, and Sanders. Functional outcomes evaluated with a Musculoskeletal Functional Assessment (MFA). The mean follow-up was 4.3 years. The mean MFA score was 15.7 (SD = 11.6), which is not significantly different from published values for midfoot injuries, hindfoot injuries, or both, 1 year after injury (mean = 22.1, SD = 18.4). The classification systems of Crosby and Fitzgibbons, Eastwood, and Sanders, the number of fragments of the posterior facet, and payer status were not significantly associated with outcome as determined by the MFA. The Sanders classification trended toward significance. Anterior process comminution and surgeon's overall impression of severity were significantly associated with functional outcome. The amount of anterior process comminution was an important determinant of functional outcome with increasing anterior process comminution significantly associated with worsened functional outcome (P = .04). In addition, the surgeon's overall impression of severity of injury was predictive of functional outcome (P = .02), as determined by MFA. Level III, comparative series. © The Author(s) 2014.

    Full Text Available ABSTRACT Introduction: Intra-articular injection of corticosteroids (IIC for treatment of patients with juvenile idiopathic arthritis (JIA is increasingly used in Pediatric Rheumatology. Objectives: To describe the clinical course of patients undergoing IIC in our Pediatric Rheumatology Unit. Methods: Retrospective study of patients with JIA undergoing IIC from January 2008 to December 2012, with a minimum follow-up of six months after the injection. Good response to IIC was set as the presence of inactivity on the infiltrated joint by at least six months. Results: Eighty-eight patients underwent a total of 165 IICs. Of these, 75% were girls and 35.2% had persistent oligoarticular JIA. The mean age at diagnosis was 6.8 years, and when IIC was carried out, 12.2 years. Regarding patients, younger age at diagnosis (p = 0.037 and the occurrence of uveitis in the course of the disease (p = 0.015 were associated with good response to IIC. From 165 IICs, 63% had a good response and joints remained inactive for a median of 18.1 months. The type of joint injection (p = 0.001, lesser values stated in the overall visual analog scale by the physician (p = 0.015 and by parents/patient (p = 0.01 have been associated with a good response to IIC. Nine adverse events (5.4% were observed. Conclusion: In our study, more than half of the joints showed a good response to IIC. Younger patients at diagnosis and uveitis during the course of the disease had good response to IIC. Knees, wrists and elbows were the joints that best responded to IIC. IIC proved to be a safe procedure.

    The dispersion of non-steroidal antiinflammatory drugs (NSAIDs) into biodegradable polymeric matrices have been accepted as a good approach for obtaining a therapeutic effect in a predetermined period of time meanwhile minimizing the side effects of NSAIDs. In the present study, it was aimed to prepare Naproxen Sodium (NS), (a NSAID) loaded microsphere formulation using natural Bovine Serum Albumin (BSA) and synthetic biodegradable polymers such as poly(lactide-co-glycolic acid) (PLGA) (50:50 MW 34,000 and 88,000 Da) for intra-articular administration, and to study the retention of the drug at the site of injection in the knee joint. NS incorporated microspheres were evaluated in vitro for particle size (the mean particle size; for BSA microspheres, 10.0 +/- 0.3 microm, for PLGA microspheres, 9.0 +/- 0.2 and 5.0 +/- 0.1 microm for MW 34,000 and 88,000 Da, respectively), yield value, drug loading, surface morphology and drug release. For in vivo studies, monoarticular arthritis was induced in the left knee joints of rabbits by using ovalbumin and Freund's Complete Adjuvant as antigen and adjuvant. A certain time (4 days) is allowed for the formation of arthritis in the knee joints, then the NS loaded microspheres were injected directly into the articular cavity. At specific time points, gamma scintigrams were obtained to determine the residence time of the microspheres in knee joints, in order to determine the most suitable formulation. This study indicated that PLGA, a synthetic polymer, is more promising than the natural type BSA microspheres for an effective cure of mono-articular arthritis in rabbits.

    Compare the effectiveness of ultrasound and fluoroscopy to guide intra-articular injections (IAI) in selected cases. A prospective study in our outpatient clinics at the Rheumatology Division at Universidade Federal de São Paulo (UNIFESP), Brazil, was conducted to compare the short-term (4 weeks) effectiveness of ultrasound and fluoroscopy-guided IAI in patients with rheumatic diseases. Inclusion criteria were: adults with refractory synovitis undergoing IAI with glucocorticoid. All patients had IAI performed with triamcinolone hexacetonide (20mg/ml) with varying doses according to the joint injected. A total of 71 rheumatic patients were evaluated (52 women, 44 whites). Mean age was 51.9 ± 13 years and 47 of them (66.2%) were on regular DMARD use. Analysis of the whole sample (71 patients) and hip sub-analysis (23 patients) showed that significant improvement was observed for both groups in terms of pain (P < 0.001). Global analysis also demonstrated better outcomes for patients in the FCG in terms of joint flexion (P < 0.001) and percentage change in joint flexion as compared to the USG. Likert scale score analyses demonstrated better results for the patients in the USG as compared to the FCG at the end of the study (P < 0.05). No statistically significant difference between groups was observed for any other study variable. Imaging-guided IAI improves regional pain in patients with various types of synovitis in the short term. For the vast majority of variables, no significant difference in terms of effectiveness was observed between fluoroscopy and ultrasound guided IAI.

    Purpose  Multifragmentary intra-articular fractures displaced in multiple planes are a challenge. We use a reproducible technique of fracture and articular reduction using an initial volar approach targeting reduction in the volar lunate facet first with plate and unicortical locking screws. This creates a template for reduction in dorsal fragments through a dorsal approach. Our study investigated the radiological, clinical, and functional outcomes of patients treated with this technique. Materials and Methods  We reviewed the postoperative radiographs and notes of 18 patients that had this method of fixation between the years 2008 and 2015, the mean age being 43. These patients were reviewed functionally on average 2 years and 3 months following their definitive operation. Results  Normal alignment and length to the distal radius were restored with on average a 0.6 mm articular step. The average range of motion was 64% and preservation of grip strength was 71% compared with the uninjured wrist. Functional assessment averages were 29 for both the quick Disabilities of the Arm, Shoulder and Hand (DASH) and for Patient Rated Wrist Evaluation. The modified system of Green and O'Brien had results of good in 10, fair in 7, and poor in 1. With respect to the Gartland and Werley system, three patients had an excellent result, four had a good result, six had a fair result, and five had a poor result. The mean arthritic grading was 1 (grading 0-3) according to Knirk and Jupiter. Conclusion  This reproducible technique provides an option for these devastating fractures providing a functioning wrist with all of the patients returning to their original form of employment.

The program consisted of five intra-articular knee injections of sodium hyaluronate (Hyalgan®, with each injection given 1 week apart, structured physical therapy, knee bracing, and patient education. Clinical outcomes included knee pain severity, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC subscores, current medication use, and history of total knee arthroplasty. Base-case, subgroup, and sensitivity analyses were conducted to determine the incremental cost-effectiveness ratio (ICER of the treatment program with comparisons made to historical literature controls undergoing usual care. Results: A total of 218 patients (54% provided long-term follow-up data. Knee pain severity decreased 60% and WOMAC subscores decreased 33%–42% compared to baseline (all p<0.001. Total knee arthroplasty was performed in 22.8% (81/356 of knees during follow-up. The treatment program was highly cost-effective compared to usual care with a base-case ICER of $6,000 per quality-adjusted life year (QALY. Results of subgroup analyses, one-way deterministic sensitivity analyses, and second-order probabilistic sensitivity analyses resulted in ICERs ranging from $3,996 to $10,493 per QALY.

    Edema surrounding the medial collateral ligament (MCL) is seen on MR imaging in patients with MCL injuries and in patients with radiographic osteoarthritis in the non-traumatic knee. Because we noted MCL edema in patients without prior trauma or osteoarthritis, we studied the association between intra-articular pathology and MCL edema in patients without knee trauma. We evaluated the MR examinations of 247 consecutive patients (121 male, 126 female with a mean age of 44 years) without recent trauma for the presence of edema surrounding the MCL, meniscal and ACL tears, medial meniscal extrusion, medial compartment chondromalacia, and osteoarthritis. The percentages of patients illustrating MCL edema with and without each type of pathology were compared using Fisher's exact test to determine if there was a statistically significant association. We found MCL edema in 60% of 247 patients. MCL edema was present in 67% of patients with medial meniscal tears, 35% with lateral meniscal tears, 100% with meniscal extrusion of 3 mm or more, 78% with femoral chondromalacia, 82% with tibial chondromalacia, and 50% with osteoarthritis. The percentage of patients with edema increased with the severity of the chondromalacia. These associations were all statistically significant (p <0.02). The mean age of those with MCL edema was 49.7 years compared with 34.9 years without MCL edema (p <0.001). Patient gender and ACL tear did not correlate with MCL edema. Nine (4%) of the 247 patients had MCL edema without intra-articular pathology. None of these 9 patients had MCL tenderness or joint laxity on physical examination. We confirmed that MCL edema is associated with osteoarthritis, but is also associated with meniscal tears, meniscal extrusion, and chondromalacia. In addition, MCL edema can be seen in patients without intra-articular pathology, recent trauma or MCL abnormality on physical examination. (orig.)

    Purpose: To evaluate the influence of shorter- and longer-acting intra-articular anaesthetics on post-arthrographic pain. Materials and methods: 154 consecutive patients investigated by MR or CT arthrographies were randomly assigned to one of the following groups: 1 – intra-articular contrast injection only; 2 – lidocain 1% adjunction; or 3 – bupivacain 0.25% adjunction. Pain was assessed before injection, at 15 min, 4 h, 1 day and 1 week after injection by visual analogue scale (VAS). Results: At 15 min, early mean pain score increased by 0.96, 0.24 and 0 in groups 1, 2 and 3, respectively. Differences between groups 1 and 3 and 1 and 2 were statistically significant (p = 0.003 and 0.03, respectively), but not between groups 2 and 3 (p = 0.54). Delayed mean pain score increase was maximal at 4 h, reaching 1.60, 1.22 and 0.29 in groups 1, 2 and 3, respectively. Differences between groups 1 and 2 and 2 and 3 were statistically significant (p = 0.002 and 0.02, respectively), but not between groups 1 and 2 (p = 0.46). At 24 h and 1 week, the interaction of local anaesthetics with increase in pain score was no longer significant. Results were independent of age, gender and baseline VAS. Conclusion: Intra-articular anaesthesia may significantly reduce post-arthrographic pain. Bupivacain seems to be more effective than lidocain to reduce both early and delayed pain

    The purpose of the study was to evaluate the results of surgical treatment in athletes with associated intra-articular hip pathology and extra-articular sports pubalgia. Between December 2003 and September 2009, 37 hips (mean patient age, 25 years) were diagnosed with both symptomatic athletic pubalgia and symptomatic intra-articular hip joint pathology. There were 8 professional athletes, 15 collegiate athletes, 5 elite high school athletes, and 9 competitive club athletes. Outcomes included an evaluation regarding return to sports and modified Harris Hip Score, Short Form 12 score, and visual analog scale score. We evaluated 37 hips at a mean of 29 months (range, 12 to 78 months) after the index surgery. Thirty-one hips underwent thirty-five athletic pubalgia surgeries. Hip arthroscopy was performed in 32 hips (30 cases of femoroacetabular impingement treatment, 1 traumatic labral tear, and 1 borderline dysplasia). Of 16 hips that had athletic pubalgia surgery as the index procedure, 4 (25%) returned to sports without limitations, and 11 (69%) subsequently had hip arthroscopy at a mean of 20 months after pubalgia surgery. Of 8 hips managed initially with hip arthroscopy alone, 4 (50%) returned to sports without limitations, and 3 (43%) had subsequent pubalgia surgery at a mean of 6 months after hip arthroscopy. Thirteen hips had athletic pubalgia surgery and hip arthroscopy at one setting. Concurrent or eventual surgical treatment of both disorders led to improved postoperative outcomes scores (P pubalgia or intra-articular hip pathology in this patient population, outcomes were suboptimal. Surgical management of both disorders concurrently or in a staged manner led to improved postoperative outcomes scoring and an unrestricted return to sporting activity in 89% of hips.

    The use of isoflupredone acetate in performance horses and the scarcity of published pharmacokinetic data necessitate further study. The objective of the current study was to describe the plasma pharmacokinetics of isoflupredone acetate as well as time-related urine and synovial fluid concentrations following intra-articular administration to horses. Twelve racing-fit adult Thoroughbred horses received a single intra-articular administration (8 mg) of isoflupredone acetate into the right antebrachiocarpal joint. Blood, urine and synovial fluid samples were collected prior to and at various times up to 28 days post drug administration. All samples were analyzed using liquid chromatography-Mass Spectrometry. Plasma data were analyzed using a population pharmacokinetic compartmental model. Maximum measured plasma isoflupredone concentrations were 1.76 ± 0.526 ng/mL at 4.0 ± 1.31 h and 1.63 ± 0.243 ng/mL at 4.75 ± 0.5 h, respectively, for horses that had synovial fluid collected and for those that did not. The plasma beta half-life was 24.2 h. Isoflupredone concentrations were below the limit of detection in all horses by 48 h and 7 days in plasma and urine, respectively. Isoflupredone was detected in the right antebrachiocarpal and middle carpal joints for 8.38 ± 5.21 and 2.38 ± 0.52 days, respectively. Results of this study provide information that can be used to regulate the use of intra-articular isoflupredone in the horse. Copyright © 2015 John Wiley & Sons, Ltd.

    Methylprednisolone acetate (MPA) is commonly administered to performance horses, and therefore, establishing appropriate withdrawal times prior to performance is critical. The objectives of this study were to describe the plasma pharmacokinetics of MPA and time-related urine and synovial fluid concentrations following intra-articular administration to sixteen racing fit adult Thoroughbred horses. Horses received a single intra-articular administration of MPA (100 mg). Blood, urine, and synovial fluid samples were collected prior to and at various times up to 77 days postdrug administration and analyzed using tandem liquid chromatography-mass spectrometry (LC-MS/MS). Maximum measured plasma MPA concentrations were 6.06 ± 1.57 at 0.271 days (6.5 h; range: 5.0-7.92 h) and 6.27 ± 1.29 ng/mL at 0.276 days (6.6 h; range: 4.03-12.0 h) for horses that had synovial fluid collected (group 1) and those that did not (group 2), respectively. The plasma terminal half-life was 1.33 ± 0.80 and 0.843 ± 0.414 days for groups 1 and 2, respectively. MPA was undetectable by day 6.25 ± 2.12 (group 1) and 4.81 ± 2.56 (group 2) in plasma and day 17 (group 1) and 14 (group 2) in urine. MPA concentrations in synovial fluid remained above the limit of detection (LOD) for up to 77 days following intra-articular administration, suggesting that plasma and urine concentrations are not a good indicator of synovial fluid concentrations. © 2013 John Wiley & Sons Ltd.

    Intra-articular injection (IAI) of both hyaluronic acid (HA) and depot-steroid preparations had the advantage of quick and prolonged favorable effects on pain relief among patients with symptomatic osteoarthritis of the knee (OAK). The effect of IAI of HA on the systemic effects of the intra-articular steroids had not been investigated. Non-selected patients attending the rheumatology clinic with symptomatic OAK who failed NSAIDS and physical therapy were offered an IAI of HA at the knee joint followed 20 min later by an IAI of 1 ml of Celestone Chronodose at the same joint (group 1). Morning serum levels of cortisol were obtained just prior to the IAI and 1, 2 and 8 days later. Demographic, clinical, and laboratory parameters were obtained also from all the patients. Age- and sex-matched group of patients from the same clinic were recruited as a control group (group 2). Mean baseline serum cortisol levels in group 1 was 381 ± 154 mmol/l vs. 376 ± 119 in group 2 (p = 0.954). Morning serum cortisol levels at day 1 and day 2 were 24 ± 6 and 22 ± 6 mmol/l, respectively, in group 1 patients vs. 27 ± 5.8 (p = 0.214) and 25 ± 5.6 mmol/l (p = 0.200), respectively, in group 2. These levels were significantly lower than baseline levels in each group. Morning serum cortisol levels at day 8 in group 1 and group 2 were 349 ± 128 and 314 ± 99 mmol/l, respectively (p = 0.419). Pre-injection of HA at the knee joint did not affect the systemic effect on the hypothalamic-pituitary-adrenal axis of IAI of Celestone Chronodose.

    Full Text Available Abstract Background Treatment of distal tibial intra-articular fractures is challenging due to the difficulties in achieving anatomical reduction of the articular surface and the instability which may occur due to ligamentous and soft tissue injury. The purpose of this study is to present an algorithm in the application of external fixation in the management of intra-articular fractures of the distal tibia either from axial compression or from torsional forces. Materials and methods Thirty two patients with intra-articular fractures of the distal tibia have been studied. Based on the mechanism of injury they were divided into two groups. Group I includes 17 fractures due to axial compression and group II 15 fractures due to torsional force. An Ilizarov external fixation was used in 15 patients (11 of group I and 4 of group II. In 17 cases (6 of group I and 11 of group II a unilateral hinged external fixator was used. In 7 out of 17 fractures of group I an additional fixation of the fibula was performed. Results All fractures were healed. The mean time of removal of the external fixator was 11 weeks for group I and 10 weeks for group II. In group I, 5 patients had radiological osteoarthritic lesions (grade III and IV but only 2 were symptomatic. Delayed union occurred in 3 patients of group I with fixed fibula. Other complications included one patient of group II with subluxation of the ankle joint after removal of the hinged external fixator, in 2 patients reduction found to be insufficient during the postoperative follow up and were revised and 6 patients had a residual pain. The range of ankle joint motion was larger in group II. Conclusion Intra-articular fractures of the distal tibia due to axial compression are usually complicated with cartilaginous problems and are requiring anatomical reduction of the articular surface. Fractures due to torsional forces are complicated with ankle instability and reduction should be augmented with ligament

    Even with the invention of locking plates, intra-articular fractures of distal radius with extreme comminution remain a challenge for orthopaedic surgeons. Osteochondral graft is a potential choice to reconstruct the articular defect. We report a patient who had a fracture of distal radius with costo-osteochondral graft for articular reconstruction which has not yet been described in the English literature. At nine-year follow-up, he was pain free and had full range of movement of the wrist. The authors suggest that costo-osteochondral graft could be an option with satisfactory result.

    The aim was to identify factors explaining inconsistent observations concerning the efficacy of intra-articular hyaluronic acid compared to intra-articular sham/control, or non-intervention control, in patients with symptomatic osteoarthritis, based on randomized clinical trials (RCTs). A systematic review and meta-regression analyses of available randomized trials were conducted. The outcome, pain, was assessed according to a pre-specified hierarchy of potentially available outcomes. Hedges׳s standardized mean difference [SMD (95% CI)] served as effect size. REstricted Maximum Likelihood (REML) mixed-effects models were used to combine study results, and heterogeneity was calculated and interpreted as Tau-squared and I-squared, respectively. Overall, 99 studies (14,804 patients) met the inclusion criteria: Of these, only 71 studies (72%), including 85 comparisons (11,216 patients), had adequate data available for inclusion in the primary meta-analysis. Overall, compared with placebo, intra-articular hyaluronic acid reduced pain with an effect size of -0.39 [-0.47 to -0.31; P hyaluronic acid. Based on available trial data, intra-articular hyaluronic acid showed a better effect than intra-articular saline on pain reduction in osteoarthritis. Publication bias and the risk of selective outcome reporting suggest only small clinical effect compared to saline. Copyright © 2016 Elsevier Inc. All rights reserved.

    We performed a meta-analysis of randomized controlled trials (RCTs) to compare the efficacy and safety of intra-articular methylprednisolone and hyaluronic acid (HA) in term of pain reduction and improvements of knee function in patients with knee osteoarthritis (OA). The PubMed, EMBASE, ScienceDirect, and Cochrane Library databases were systematically searched for literature up to January 2018. RCTs involving HA and methylprednisolone in knee OA were included. Two independent reviewers performed independent data abstraction. The I 2 statistic was used to assess heterogeneity. A fixed or random effects model was adopted for meta-analysis. All meta-analyses were performed by using STATA 14.0. Five RCTs with 1004 patients were included in the meta-analysis. The present meta-analysis indicated that there were no significant differences in terms of WOMAC pain, physical function and stiffness at 4 week, 12 weeks and 26 weeks between HA and methylprednisolone groups. No increased risk of adverse events were identified in both groups. Both HA and methylprednisolone injections were effective therapies for patients with knee OA. Methylprednisolone showed comparable efficacy in reducing pain and improving functional recovery to HA. And no significant difference was found in long-term of follow-up in terms of adverse effects.

    Full Text Available The purpose of this study was to compare the efficacy of the intra-articular (IA hyaluronic acid injection to traditional conservative treatment (TCT in dogs with osteoarthritis (OA induced by hip dysplasia. Sixteen dogs were distributed into two groups: Hyal: IA injection of hyaluronic acid (5–10 mg, and Control: IA injection with saline solution (0.5–1.0 mL in combination with a TCT using an oral nutraceutical (750–1000 mg every 12 h for 90 days and carprofen (2.2 mg/kg every 12 h for 15 days. All dogs were assessed by a veterinarian on five occasions and the owner completed an assessment form (HCPI and CPBI at the same time. The data were analyzed using unpaired t test, ANOVA, and Tukey’s test (P<0.05. Compared with baseline, lower scores were observed in both groups over the 90 days in the veterinarian evaluation, HCPI, and CPBI (P<0.001. The Hyal group exhibited lower scores from 15 to 90 and 60 to 90 days, in the CBPI and in the veterinarian evaluation, respectively, compared to the Control group. Both treatments reduced the clinical signs associated with hip OA. However, more significant results were achieved with intra-articular hyaluronic acid injection.

    This study was performed to compare the efficacy of treatment in three groups of patients with knee osteoarthritis (OA) given an intra-articular injection of platelet-rich plasma (PRP), hyaluronic acid (HA) or ozone gas. A total of 102 patients with mild-moderate and moderate knee OA who presented at the polyclinic with at least a 1-year history of knee pain and VAS score ≥4 were randomly separated into three groups. Group 1 (PRP group) received intra-articular injection of PRP × 2 doses, Group 2 (HA group) received a single dose of HA, and Group 3 (Ozone group) received ozone × four doses. Weight-bearing anteroposterior-lateral and Merchant's radiographs of both knees were evaluated. WOMAC and VAS scores were applied to all patients on first presentation and at 1, 3, 6 and 12 months. At the end of the 1st month after injection, significant improvements were seen in all groups. In the 3rd month, the improvements in WOMAC and VAS scores were similar in Groups 1 and 2, while those in Group 3 were lower (p injections, as the application alone was sufficient to provide at least 12 months of pain-free daily living activities.

    The objective of this study was to assess the safety and efficacy of intra-articular injections of hyaluronic acid (HA) versus saline for symptomatic treatment of osteoarthritis (OA). Twenty-five adult purpose-bred dogs underwent meniscal release of one knee. Clinical, arthroscopic, and radiographic signs of OA were confirmed in all dogs prior to treatment. Dogs were randomized into five groups: HA-1 (n = 5), HA-3 (n = 5), HA-5 (n = 5), Saline-1 (n = 5), and Saline-3 (n = 5). Each dog received intra-articular injections of the respective substance into the affected knee at the pre-determined time points. Dogs were assessed for heat, swelling, and erythema after each injection and for lameness, pain, effusion, range of motion, kinetics, radiographic OA scoring, and arthroscopic scoring prior to treatment and for 6 months after injection. Dogs were then humanely euthanatized and the knees assessed grossly and histologically. Only mild heat, swelling, and/or erythema were noted in some dogs following injection and resolved within 1 week. Dogs treated with HA-1, HA-3, and HA-5 were significantly (p injection protocols were safe, superior to saline for short-term amelioration of symptoms associated with chronic OA, and can be translated to human OA treatment. © 2016 Orthopaedic Research Society.

Fluorescence imaging was used to visualize the distribution of nanoparticles after intra-articular injection. The chondrocyte-targeting efficiency and cellular uptake mechanism of HA-BSANPs were investigated using endocytic inhibitors.Results: HA-BSANPs were successfully prepared with HA coating the surface and amorphous drug in the core. Compared with BSANPs, HA-BSANPs exhibited improved uptake by chondrocytes through a receptor-mediated active uptake mechanism. The endocytosis process of BSANPs and HA-BSANPs involved clathrin-mediated endocytosis, caveolae-mediated endocytosis, and macropinocytosis. No apparent thickening or hyperplasia of the synovium was observed in either BSANPs or HA-BSANPs. The HA-BSANPs could reside in the articular cavity of rats for more than 14 days, which was significantly longer than BSANPs.Conclusion: HA-BSANPs are a promising carrier for articular-related diseases due to elongated articular residence and improved chondrocytic accumulation.Keywords: chondrocyte, intra-articular injection, hyaluronic acid, BSA, nanoparticles

    The aims of this study were to prepare fine intra-articular-administrated chitosan thermosensitive hydrogels combined with alginate microspheres and to investigate the possibility of those hydrogels as a drug delivery system for promoting the anti-inflammation effect. Diclofenac sodium containing alginate microspheres was prepared by a modified emulsification and/or gelation method and then dispersed into injectable thermosensitive hydrogels, consisting of chitosan and β-glycerophosphate. The final combined hydrogels were evaluated in terms of their morphology properties, rheological properties, in vitro drug release, and in vivo biocompatibility and pharmacodynamics behaviors. The optimized formulation exhibited sol-gel transition at 31.72 ± 0.42°C and quickly turned into gel within 5 min, with sustained drug release characteristics followed Ritger-Peppas equation, which could prolong the in vitro drug release to 5 days. In addition, the anti-inflammation efficacy of the combined hydrogels in rabbits with experimental rheumatoid arthritis was higher than that of drug solution and pure chitosan hydrogels. Those results demonstrated that these combined hydrogels could become a potential drug delivery system for improving the therapeutic effect of diclofenac sodium and suggested an important technology platform for intra-articular administration.

    As a potential treatment for osteoarthritis (OA), we have developed injectable and hydrolytically degradable heparin-based biomaterials with tunable sulfation for the intra-articular delivery of tumor necrosis factor-alpha stimulated gene-6 (TSG-6), a protein known to inhibit plasmin which may degrade extracellular matrix within OA joints. We first assessed the effect of heparin sulfation on TSG-6 anti-plasmin activity and found that while fully sulfated (Hep) and heparin desulfated at only the N position (Hep-N) significantly enhanced TSG-6 bioactivity in vitro, fully desulfated heparin (Hep-) had no effect, indicating that heparin sulfation plays a significant role in modulating TSG-6 bioactivity. Next, TSG-6 loaded, degradable 10 wt% Hep-N microparticles (MPs) were delivered via intra-articular injection into the knee at 1, 7, and 15 days following medial meniscal transection (MMT) injury in a rat model. After 21 days, cartilage thickness, volume, and attenuation were significantly increased with soluble TSG-6, indicating degenerative changes. In contrast, no significant differences were observed with TSG-6 loaded MP treatment, demonstrating that TSG-6 loaded MPs reduced cartilage damage following MMT injury. Ultimately, our results indicate that Hep-N can enhance TSG-6 anti-plasmin activity and that Hep-N-based biomaterials may be an effective method for TSG-6 delivery to treat OA.

  18. Intra-articular nerve growth factor regulates development, but not maintenance, of injury-induced facet joint pain & spinal neuronal hypersensitivity.

    Science.gov (United States)

    Kras, J V; Kartha, S; Winkelstein, B A

    2015-11-01

    The objective of the current study is to define whether intra-articular nerve growth factor (NGF), an inflammatory mediator that contributes to osteoarthritic pain, is necessary and sufficient for the development or maintenance of injury-induced facet joint pain and its concomitant spinal neuronal hyperexcitability. Male Holtzman rats underwent painful cervical facet joint distraction (FJD) or sham procedures. Mechanical hyperalgesia was assessed in the forepaws, and NGF expression was quantified in the C6/C7 facet joint. An anti-NGF antibody was administered intra-articularly in additional rats immediately or 1 day following facet distraction or sham procedures to block intra-articular NGF and test its contribution to initiation and/or maintenance of facet joint pain and spinal neuronal hyperexcitability. NGF was injected into the bilateral C6/C7 facet joints in separate rats to determine if NGF alone is sufficient to induce these behavioral and neuronal responses. NGF expression increases in the cervical facet joint in association with behavioral sensitivity after that joint's mechanical injury. Intra-articular application of anti-NGF immediately after a joint distraction prevents the development of both injury-induced pain and hyperexcitability of spinal neurons. Yet, intra-articular anti-NGF applied after pain has developed does not attenuate either behavioral or neuronal hyperexcitability. Intra-articular NGF administered to the facet in naïve rats also induces behavioral hypersensitivity and spinal neuronal hyperexcitability. Findings demonstrate that NGF in the facet joint contributes to the development of injury-induced joint pain. Localized blocking of NGF signaling in the joint may provide potential treatment for joint pain. Copyright © 2015 Osteoarthritis Research Society International. Published by Elsevier Ltd.

    Purpose: The prospective investigation of the therapeutic effect of CT-guided intra-articular corticosteroid injection into inflammatory sacroiliac (SI) joints compared to conventional treatment with nonsteroidal anti-inflammatory drugs (NSAIDS) in children with juvenile spondyloarthropathy (jSpA) and the determination of the role of dynamic magnetic resonance imaging (MRI) in establishing the indication and monitoring the therapy. Materials and Methods: The study comprises 89 children with known jSpA who were diagnosed by MRI to have a unilateral or bilateral sacroiliitis. Therapy with NSAIDS was initiated or continued in all 89 patients. Four weeks after the diagnostic MRI, two groups were distinguished according to the clinical response of NSAIDS, with group 1 consisting of 22 responders and group 2 of 56 non-responders. The patients of group 2 were treated with CT-guided intra-articular corticosteroid injection (low-dose injection) while the therapy with NSAIDS was continued. A total of 83 SI joints were punctured without complications, 27 bilaterally and 29 unilaterally. The indication for the intervention was based on inflammatory activity as determined by MRI. The therapy was monitored by clinical follow-up every 8 to 12 weeks over a period of 20 months. Follow-up by dynamic MRI was performed in all 56 children of group 2 and 15 of the 33 children of group 1 within 8{+-}4 months of the initial examination. Results: A total of 87.5% of the children in group 2 showed a statistically signficant decrease in their subjective complaints from 6.9{+-}3.4 to 1.8{+-}1.7 (p<0.05) as measured on a visual analog scale (VAS from 0 to 10). Improvement was seen as early as 1.5{+-}1.0 weeks after the intervention and lasted for a mean of 12{+-}6 months. The children in group 1 already showed similar improvement of the VAS from 6.8{+-}3.2 to 1.5{+-}1.4 (p<0.05) during the initial four weeks of NSAIDS therapy, with the improvement lasting for the 20-month observation period

    This study aimed to describe patients treated for knee osteoarthritis between 2006 and 2013 in France and to compare the delay from diagnosis to total knee replacement between patients who received intra-articular hyaluronic acid injections and those who did not receive the injections. A second objective was to compare direct medical costs for ambulatory care between treatment groups. Patients were selected from a representative sample of the real world administrative claims database using an algorithm developed by experts from the scientific committee of the study. Data were matched with the medico-administrative database for hospital care. A Cox proportional hazards model was stratified for the treatment group and adjusted for available socio-demographic and medical covariates to compare restricted mean survival times at different time points (1, 3, 5 and 7.5 years) between groups. Costs were expressed in 2013 euros. A total of 14,782 patients were treated for knee osteoarthritis (67% women; mean age = 68 years). Among this population, 1,662 patients had total knee replacement (11.2%). At each time point, restricted mean survival time without total knee replacement was significantly higher (p-valueshyaluronic acid group, from +51 to +217 days at 1 and 7.5 years, respectively. For the year preceding total knee replacement, the means for total direct medical costs were similar between groups, €744 vs €805 for treatment and control groups, respectively, (p-value = 0.104). Intra-articular injections accounted for less than 10% of the total costs. This is the first retrospective longitudinal study involving knee osteoarthritis patients using medico-administrative databases in France. The results support the effectiveness of hyaluronic acid injections in delaying total knee replacement and show that patients treated with hyaluronic acid have similar direct medical costs for ambulatory care compared to patients treated with corticosteroids only.

    ABSTRACT Intra-articular osteoid osteoma (IAOO) of the hip is a relatively rare diagnosis, but one that can closely mimic symptomatic presentation of femoroacetabular impingement (FAI). Although there are multiple case reports of osteoid osteoma (OO) in the hip, we present the largest case series of hip IAOO treated with hip arthroscopy and discuss limited patient-reported outcomes after treatment with hip arthroscopy. We retrospectively identified patients diagnosed with IAOO of the hip with confirmatory computed tomography, magnetic resonance imaging or biopsy diagnoses of OO. We analyzed lesion location, main presenting symptoms, symptom duration and treatment undertaken. For the patients who underwent hip arthroscopy for treatment of their IAOO, we reviewed patient-reported outcome scores when available. Forty patients with confirmed IAOO were identified. Thirteen underwent excision with hip arthroscopy. The most common presenting symptom was groin pain. In limited patients who had pre- and post-operative outcome scores, we found significant improvements in modified Harris Hip Score (mHHS), Hip Outcome Score-Activity of Daily Living (HOS-ADL) and international Hip Outcomes Tool (iHot33) scores. Compared with patients undergoing hip arthroscopy for FAI alone, baseline mHHS, HOS-ADL, Hip Outcome Score–Sport-Specific Subscale and iHot33 scores were almost identical. We found that the presenting symptoms of hip IAOO closely mimic symptomatic FAI, including groin pain and anterior hip pain, so it is important to keep IAOO of the hip in the differential diagnosis of hip pain. Based on our experience, arthroscopy can be an effective treatment option for excision of intra-articular OO and is especially effective in patients with concomitant FAI in treating both pathologies.

    The objective of this study is to assess the safety and efficacy of repeated intra-articular injection of high molecular weight hyaluronic acid (LBSA0103) at a 26-week interval, in patients with osteoarthritis of the knee. The study was an open-label, single arm, multicentre prospective trial conducted in patients with symptomatic knee osteoarthritis. The intervention consisted of two intra-articular injections of LBSA0103, with the second injection performed 26 weeks after the first injection. The primary outcome was the incidence of adverse drug reactions related to each injection. Assessment of efficacy of repeated injections in terms of maintenance of pain relief was a secondary objective of this study. Of the 185 patients screened, 174 patients received the first injection and 153 patients received both injections of LBSA0103. Nine adverse drug reactions occurred in seven patients (4.02%) after the first injection, while only one adverse drug reaction occurred (0.65%) after the second injection. As a secondary outcome measure, the improvements in the efficacy parameters including total WOMAC score and weight-bearing pain were all significant at both week 13 and 39 compared to the baseline value (P injection were consistent with those after the initial injection of LBSA0103 (between week 26 and week 39, P injection of LBSA0103 at a 26-week interval is safe without increased risk of adverse drug reactions. Additionally, LBSA0103 is effective in reduction of osteoarthritis knee pain and in maintenance of pain reduction for a 39-week period when a second injection is administered.

The primary outcomes are Western Ontario and McMaster Universities Arthritis Index (WOMAC) pain scores and WOMAC function scores. Each outcome was combined and calculated using the statistical software STATA 12.0. Fixed/random effect model was adopted based on the heterogeneity tested by I statistic. A total of 739 patients were analyzed across 4 randomized controlled trials (RCTs). The present meta-analysis revealed that there were significant differences between groups regarding the WOMAC pain scores at 4 weeks (WMD = -1.384, 95% CI: -1.975 to -0.793, P = .000), 12 weeks (WMD = -1.587, 95% CI: -2.489 to -0.685, P = .001), and 24 weeks (WMD = -1.563, 95% CI: -2.245 to -0.881, P = .000). Significant differences were identified in terms of physical function at 4 weeks (WMD = -7.925, 95% CI: -13.359 to -2.491, P = .004), 12 weeks (WMD = -7.314, 95% CI: -13.308 to -1.320, P = .117), and 24 weeks (WMD = -6.484, 95% CI: -11.256 to -1.711, P = .008). Intra-articular methylprednisolone injection was associated with an improved pain relief and physical function in patients with knee osteoarthritis. Additionally, no severe adverse effects were observed. Due to the limited quality of the evidence currently available, higher quality RCTs were required.

    To determine the effectiveness of a protocol for the treatment of fracture-dislocations of the elbow based on the concept that, if dislocation of the elbow with associated fractures can be made to resemble a simple elbow dislocation by repairing or reconstructing the fractured structures, repair of the medial collateral ligament (MCL) will not be necessary. Over a 5-year period, a single surgeon operated on 34 patients with a posterior dislocation of the elbow associated with one or more intra-articular fractures. The mean age of these 19 men and 15 women was 48 years. Associated fractures included the capitellum, trochlea, and lateral epicondyle in 3 patients; the olecranon in 1 patient; and the radial head in 30 patients (with concomitant fracture of the coronoid process-the so-called "terrible triad" of the elbow-in 22 patients, and concomitant fracture of the coronoid and olecranon in 1 patient). Operative treatment consisted of open reduction internal fixation (ORIF) or prosthetic replacement of all fractures and reattachment of the origin of the lateral collateral ligament (LCL) complex to the lateral epicondyle. The MCL was not repaired. Two patients (1 with a terrible triad injury and 1 with fracture of the capitellum and trochlea) had postoperative instability related to noncompliance, had reconstructive procedures, and were considered failures. An average of 32 months after injury, the remaining 32 patients regained an average of 120 degrees ulnohumeral motion and 142 degrees forearm rotation. Twenty-five of 34 patients (74%) had good or excellent results according to the system of Broberg and Morrey. Patients with terrible triad injuries had an average of 117 degrees ulnohumeral motion and 137 degrees forearm rotation, and 17 of 22 patients (77%) had good or excellent results. MCL repair is unnecessary in the treatment of dislocation of the elbow with associated intra-articular fractures, provided that the articular fractures and the LCL are repaired or

    Full Text Available CONTEXT AND OBJECTIVE: Osteoarthritis causes pain and disability in a high percentage of elderly people. The aim of the present study was to assess the efficacy of intra-articular morphine and bupivacaine on the joint flexion and extension angles of patients with knee osteoarthritis. DESIGN AND SETTING: A randomized double-blind study was performed at a pain clinic of Universidade Federal de São Paulo. METHODS: Thirty-nine patients with pain for more than three months, of intensity greater than three on a numerical scale (zero to 10, were included. G1 patients received 1 mg (1 ml of morphine diluted in 9 ml of saline, intra-articularly, and G2 patients received 25 mg (10 ml of 0.25% bupivacaine without epinephrine. Pain was assessed on a numerical scale and knee flexion and extension angles were measured after administration of the drugs at rest and during movement. The total amount of analgesic supplementation using 500 mg doses of paracetamol was also determined. RESULTS: No significant difference in pain intensity was observed between G1 and G2. Significant decreases in pain at rest and during movement and significant increases in mean flexion and extension angles were observed in both groups, with no significant difference between the two groups. The mean total amount of paracetamol used over a seven-day period was 3578 mg in G1 and 5333 mg in G2 (P = 0.2355; Mann-Whitney test. CONCLUSION: The analgesic effects of 1 mg of morphine and 25 mg of 0.25% bupivacaine were similar among patients with osteoarthritis of the knee.

    Full Text Available Osteoarthritis (OA is one of the leading musculoskeletal disorders in the adult population. It is associated with cartilage damage triggered by the deterioration of the extracellular matrix tissue. The present study explores the effect of intra-articular injection of autologous microfragmented adipose tissue to host chondrocytes and cartilage proteoglycans in patients with knee OA. A prospective, non-randomized, interventional, single-center, open-label clinical trial was conducted from January 2016 to April 2017. A total of 17 patients were enrolled in the study, and 32 knees with osteoarthritis were assessed. Surgical intervention (lipoaspiration followed by tissue processing and intra-articular injection of the final microfragmented adipose tissue product into the affected knee(s was performed in all patients. Patients were assessed for visual analogue scale (VAS, delayed gadolinium-enhanced magnetic resonance imaging of cartilage (dGEMRIC and immunoglobulin G (IgG glycans at the baseline, three, six and 12 months after the treatment. Magnetic resonance sequence in dGEMRIC due to infiltration of the anionic, negatively charged contrast gadopentetate dimeglumine (Gd-DTPA2− into the cartilage indicated that the contents of cartilage glycosaminoglycans significantly increased in specific areas of the treated knee joint. In addition, dGEMRIC consequently reflected subsequent changes in the mechanical axis of the lower extremities. The results of our study indicate that the use of autologous and microfragmented adipose tissue in patients with knee OA (measured by dGEMRIC MRI increased glycosaminoglycan (GAG content in hyaline cartilage, which is in line with observed VAS and clinical results.

    Intra-articular injections of hyaluronic acid are potentially useful to treat ankle osteoarthritis, yet their effectiveness has not been proven. Both single and multiple-dose treatments for ankle arthritis with use of various hyaluronic acid products have been recommended, but few high-quality studies have been published. The aim of this study was to compare the effectiveness of a single intra-articular injection of hyaluronic acid with a single intra-articular injection of normal saline solution (placebo) for osteoarthritis of the ankle. Sixty-four patients with ankle osteoarthritis who met all study criteria were randomly assigned to a single intra-articular injection of 2.5 mL of low-molecular-weight, non-cross-linked hyaluronic acid or a single intra-articular injection of 2.5 mL of normal saline solution. The primary outcome measure was the change from baseline in the American Orthopaedic Foot & Ankle Society (AOFAS) clinical rating score at the six-week and twelve-week follow-up examination. Secondary outcome measures included the Ankle Osteoarthritis Scale score and patient-reported pain with use of a visual analog pain scale. Of the sixty-four patients randomized and treated, eight patients withdrew, leaving fifty-six patients who completed the entire study. There was one mild adverse event (1.6%) among the sixty-four patients. At six weeks and twelve weeks, the mean AOFAS scores in the hyaluronic acid group had improved from baseline by 4.9 and 4.9 points, respectively, whereas the mean AOFAS scores in the placebo group initially worsened by 0.4 point at six weeks and then improved by 5.4 points at twelve weeks. While the change at twelve weeks from baseline was substantial for both groups, the between-group differences were not significant. We found that a single intra-articular injection of low-molecular-weight, non-cross-linked hyaluronic acid is not demonstrably superior to a single intra-articular injection of saline solution for the treatment of

    Full Text Available Background: Despite the advances in the design and fixation of implants in total knee replacement (TKR. the amount of postoperative bleeding is still an important issue that has not been resolved. This study aimed to measure the effectiveness of various tranexamic acid administration.Methods: This was a randomized controlled trial study, held from August 2014 to February 2016 at Cipto Mangunkusumo Hospital, Jakarta. Twenty two patients having TKR were divided into three groups: the control group, the tranexamic acid intra-articular-intraoperative group, and the intravenous preoperative group. Intraoperative bleeding, haemoglobin (Hb level on preoperative to five-day-post-surgery, total drain production, total blood tranfusion needed and the drain removal timing were recorded and compared. Numerical data were analyzed by using parametric and non-parametric test, depended on the normality of the data.Results: The amount of blood transfusion needed in both the intra-articular group (200±SD 100 mL and the intravenous group (238±SD 53 mL were significantly different compared to those in the control group (1,016±SD 308.2 mL (p=0.001. Meanwhile, there was no significant difference between the amount of blood transfusion needed in the intra-articular group and the intravenous group. Total drain production in the intra-articular group (328±SD 193 mL and intravenous group (391±SD 185 mL was significantly different compared to the control group (652±SD 150 mL (p=0.003. No significant difference between the levels of both preoperative and postoperative haemoglobin, the amount of intraoperative bleeding, and the duration of drain usage.Conclusion: Intravenous and intra-articular tranexamic acid effectively decreased transfusion volume and drain production in patients undergoing TKR.

    Dexketoprofen and tramadol, alone or in combination, were evaluated after oral or intra-articular administration on knee osteoarthritis nociception induced by intra-articular (i.ar.) monosodium iodoacetate (MIA, 1 mg/25 µl) in the rat right knee while the left knee received saline (25 µl). Seven days after MIA treatment, dexketoprofen, tramadol, their combination or the vehicle were administered. Nociception was evaluated as alteration in hind limb weight distribution with Incapacitance tester at different time-points after drug administration. Oral dexketoprofen (0.1-1 mg/kg) or tramadol (0.5-5 mg/kg) induced maximal antinociception at 1 and 5 mg/kg, respectively. Their combination dose-dependently increased the intensity and duration of antinociception, that was additive and lasted up to 3 days. Also the intra-articular administration of dexketoprofen or tramadol (10-100 µg/25 µl) inhibited MIA-induced nociception, and the combination of the lower doses (10 µg/25 µl) produced a long lasting more than additive antinociceptive effect indicating a synergistic interaction between the two drugs. This effect was significantly reduced by naloxone (10 μg/25 μl, i.ar.) co-administered with both compounds. The intra-articular administration of both drugs at 10 µg/25 µl in the contralateral control knee joint provoked a marked synergistic antinociceptive effect indicating significant systemic diffusion through synovial membrane. The oral or intra-articular combination of dexketoprofen and tramadol produced additive or synergistic antinociceptive effects, respectively, in the model of MIA-induced osteoarthritis in rats, that might allow to obtain therapeutic advantages with lower side effects. © 2013 Elsevier B.V.

    Full Text Available Introduction: Intra-articular (IA local anesthetics are often used for the management and prevention of pain after arthroscopic knee surgery. Clonidine prolongs the duration of local anesthetics. In this study, analgesic effect of intra-articular administration of levobupivacaine and clonidine was compared with ropivacaine and clonidine in knee joint arthroscopic surgery under spinal anesthesia. Method: 88 patients, aged between 15 to 55 years, ASA I and II undergoing knee arthroscopy under spinal anesthesia were assigned into two equal groups (n = 44 in a randomized double blind protocol. Patients in Group L received 10 ml of 0.50% levobupivacaine and 1 mcg/kg clonidine and Group R received 10 ml of 0.75% ropivacaine and 1 mcg/kg of clonidine through intra-articular route at the end of the procedure. In the post-operative period, pain intensity was assessed by VAS (Visual Analogue Scale Score recorded at 1 st , 5 th , 8 th , 12 th , 18 th post-operative hours. Duration of analgesia, total rescue analgesic dose in first 18 hours and any side effects were also recorded. Result: Group L experienced significantly longer duration of effective postoperative analgesia and lesser rescue analgesic compared to group R. Group R had higher mean VAS score at 5 th and 12 th post-operative hours (P < 0.05. No side effects were observed among the groups. Conclusion: Intra-articular administration of levobupivacaine and clonidine give better post-operative pain relief by increasing duration of analgesia, and decreasing need of rescue analgesic compared to intra-articular ropivacaine and clonidine.

    To compare both safety and efficacy of a novel intra-articular viscosupplement made of intermediate molecular weight (MW) hyaluronic acid (HA) mixed with high concentration of mannitol with a marketed high MW HA, in patients with knee osteoarthritis (OA). Patients with symptomatic knee OA, with radiological OARSI grades 1 to 3, were enrolled in a controlled, double-blind, parallel-group, non-inferiority trial. They were randomized to receive three intra-articular injections, at weekly intervals, of either HAnOX-M made of a combination of HA (MW one to 1.5MDa, 31mg/2ml) and mannitol (70mg/2ml) or Bio-HA (MW 2.3 to 3.6MDa, 20mg/2ml). The primary outcome was six-month change in the WOMAC pain subscale (0 to 20). Sample size was calculated according to a non-inferiority margin of 1.35. Secondary endpoints included six-month change in function and walking pain, analgesic consumption and safety. The intention-to-treat (ITT) and per-protocol (PP) populations consisted of 205 and 171 patients. HAnOX-M and Bio-Ha groups did not differ statistically at baseline. The primary analysis was conducted in the PP population, then in the ITT population. The average WOMAC pain score at baseline was 9.5 in both groups. Mean (SD) variations in WOMAC pain score were -4.4 (3.8) and -4.5 (4.3) mm, for HAnOX and Bio-HA respectively, satisfying the claim for non-inferiority. Similar results were obtained for all other secondary endpoints. Treatment with of HAnOX-M is effective to alleviate knee OA symptoms and to improve joint function over six months, with similar safety than conventional HA viscosupplement. Copyright © 2016.

    Due to the growing worldwide prevalence of knee osteoarthritis, the optimal management of this issue is critical for reducing its burden. Objectives This study aimed to describe patients treated for knee osteoarthritis between 2006 and 2013 in France and to compare the delay from diagnosis to total knee replacement between patients who received intra-articular hyaluronic acid injections and those who did not receive the injections. A second objective was to compare direct medical costs for ambulatory care between treatment groups. Materials and methods Patients were selected from a representative sample of the real world administrative claims database using an algorithm developed by experts from the scientific committee of the study. Data were matched with the medico-administrative database for hospital care. A Cox proportional hazards model was stratified for the treatment group and adjusted for available socio-demographic and medical covariates to compare restricted mean survival times at different time points (1, 3, 5 and 7.5 years) between groups. Costs were expressed in 2013 euros. Results A total of 14,782 patients were treated for knee osteoarthritis (67% women; mean age = 68 years). Among this population, 1,662 patients had total knee replacement (11.2%). At each time point, restricted mean survival time without total knee replacement was significantly higher (p-valueshyaluronic acid group, from +51 to +217 days at 1 and 7.5 years, respectively. For the year preceding total knee replacement, the means for total direct medical costs were similar between groups, €744 vs €805 for treatment and control groups, respectively, (p-value = 0.104). Intra-articular injections accounted for less than 10% of the total costs. Conclusion This is the first retrospective longitudinal study involving knee osteoarthritis patients using medico-administrative databases in France. The results support the effectiveness of hyaluronic acid injections in delaying total knee

    Full Text Available BACKGROUND The aim of this prospective randomized control study is to compare the functional outcome between hydrodilatation and intraarticular steroid injection in patients with primary frozen shoulder. MATERIALS AND METHODS A total number of 52 patients who attended the orthopaedic outpatient between November 2014 and January 2016 were included in this study. The patients were categorized into two groups. Group I patients were treated with hydrodilatation method and Group II patients were treated with intra-articular steroids. Both the group of patients were advised to perform home exercise programs. The patients were assessed at baseline (before the procedure at two weeks, six weeks, three months and six months. All patients were evaluated for functional improvement by measuring the range of active movements and Constant and Murley shoulder outcome scores. RESULTS Up to three months patients treated with hydrodilatation have significantly better functional outcome as evaluated by active range of movements and Constant and Murley score. But at six months there is no significant difference in functional outcome between two methods of treatment. CONCLUSION There was improvement in functional outcome in both the methods of treatment. But patients treated by hydrodilatation showed more significant increase in functional outcome for the first three months. Home exercise forms an integral part in the management of primary frozen shoulder.

    To examine the kinetic features in patients with knee osteoarthritis (OA) after intra-articular hyaluronic acid (IAHA) injections in different time periods. A single group repeated measures study. Gait laboratory in a tertiary hospital. Twenty-five subjects with bilateral symptomatic knee OA and 15 healthy control subjects. Gait analyses were performed in both control and OA groups before (baseline), and after the completion of IAHA injections (1 week, 3 months, and 6 months). Knee pain and functional indices were assessed using a visual analogue scale (VAS) and the Lequesne function Index (LI). Joint kinetic changes were analyzed in the frontal and sagittal planes with 6-camera motion analysis system and two AMTI force plates. VAS and LI scores were both improved in OA group after IAHA injections (pinjections (pinjections can provide significant pain relief and improvement in activity of daily living function for patients with knee OA. However, the reduction in pain and the increase in knee adduction moment may last up to 6 months. This may cause excessive loading on the knee joints, which may further accelerate the rate of knee degeneration. As a result, longer study time is needed to determine whether the observed kinetic findings in this study are associated with detrimental outcomes on the knee joints. © 2015 Elsevier B.V.

    Operative treatment of an intra-articular distal radius fracture is one of the most common procedures in orthopedic and hand surgery. The intra- and interobserver agreement of common radiographical measurements of these fractures using cone beam computed tomography (CBCT) and plain radiographs were evaluated. Thirty-seven patients undergoing open reduction and volar fixation for a distal radius fracture were studied. Two radiologists analyzed the preoperative radiographs and CBCT images. Agreement of the measurements was subjected to intra-class correlation coefficient and the Bland-Altman analyses. Plain radiographs provided a slightly poorer level of agreement. For fracture diastasis, excellent intraobserver agreement was achieved for radiographs and good or excellent agreement for CBCT, compared to poor interobserver agreement (ICC 0.334) for radiographs and good interobserver agreement (ICC 0.621) for CBCT images. The Bland-Altman analyses indicated a small mean difference between the measurements but rather large variation using both imaging methods, especially in angular measurements. For most of the measurements, radiographs do well, and may be used in clinical practice. Two different measurements by the same reader or by two different readers can lead to different decisions, and therefore a standardization of the measurements is imperative. More detailed analysis of articular surface needs cross-sectional imaging modalities. (orig.)

    The purpose of this meta-analysis was to compare the blood loss and complications of intra-articular (IA) with intravenous (IV) tranexamic acid (TXA) for total knee arthroplasty (TKA). A comprehensive search of studies was conducted to identify related articles in Pubmed, Embase, Cochrane central Register of Controlled Trials, springerLink, OVID and the Research published from January 1980 to September 2016. All studies that compared IA TXA with IV TXA application on TKA were included. Main outcomes of the two methods were collected and analyzed by using Review Manager 5.3. There were 16 randomized controlled trials with 1308 cases met the criteria. Compared with IV TXA, IA TXA had similar blood volume of drainage, hidden blood loss, transfusion rate and complications (P > 0.05). IA TXA had lower total blood loss than IV TXA, and there was significant difference (P  0.05) when compared with IA TXA. Both IA TXA and single dose of IV TXA are effective in reducing total blood loss and postoperative hemoglobin drop without increasing complications of DVT or PE. The current meta-analysis suggests that 1.5 g TXA by IA administration or 1 g TXA by IV administration 10 min before tourniquet deflation is effective and safe in patients undergoing TKA.

    Full Text Available Traumatic elbow dislocations in children are rare but most of them are complex dislocations, and in such dislocations, medial humerus epicondyle fractureis the most common associated injury. Fracture incarceration in the elbow joint occurs in 5-18% of medial humerus epicondyle fractures but ulnar neuropraxia is very rare. Open reduction internal fixation is indicated in medial humerus epicondyle fracture with fracture incarceration, ulnar neuropraxia, marked instability or open fracture. Operative treatment options include fragment excision and sutures, closed or open reduction and Kirschner wire fixation, open reduction and suture fixation, open reduction and smooth pin fixation, and open reduction and screw fixation. However, ulnar nerve transposition is debatable as good outcome had been reported with and without nerve transposition. We report a case of a 13-year old boy, who presented with right elbow dislocation and intra-articular entrapment of medial humerus epicondyle fracture fragment, complicated with sensory ulnar neuropraxia, following a fall onto his right outstretched hand in a motor vehicle accident. The elbow joint was reduced using close manipulative reduction but the fracture fragment remained entrapped post-reduction. The patient then underwent open reduction and screw fixation of the medial humerus epicondyle fracture without ulnar nerve transposition. He had good functional outcome six weeks after surgical intervention, with complete recovery of ulnar neuropraxia six months later. Currently, he is doing well at school and is active with his sporting activity.

    1998-12-01

    Intra-articular calcaneal fractures are associated with significant long-term morbidity, and considerable controversy exists regarding the optimum method of treating them. The contact characteristics in the intact subtalar joint were determined at known loads and for different positions of the ankle and subtalar joint, using pressure-sensitive film (Super Low; Fuji, Itochu Canada Ltd, Montreal, Quebec). We measured the contact area to joint area ratio (pressure > 5 kg force/cm2 [kgf/cm2]) which normalizes for differences in joint size and the ratio of high pressure zone (>20 kgf/cm2) as a reflection of overall increase in joint pressure. Three simulated fracture patterns were then created and stabilized with either 1 or 2 mm of articular incongruity. Eight specimens were prepared with a primary fracture line through the posterior facet, eight with a joint depression-type fracture, and six with a central joint depression fracture. A measure of 1 to 2 mm of incongruity in the posterior facet for all three fracture patterns produced significant unloading of the depressed fragment, with a redistribution of the overall pattern of pressure distribution to parts of the facet that were previously unloaded.

    Osteoarthritis is a degenerative joint disease mostly occurring in the knee and commonly seen in middle-aged and elderly adults. Intra-articular injection of hyaluronic acid has been widely used for treatment of knee osteoarthritis. The aim of this study was to evaluate the efficacy of intra-articular injection of a novel highly cross-linked hyaluronic acid, alone or in combination with ropivacaine hydrochloride and triamcinolone acetonide, on knee articular cartilage in a rabbit model of collagenase-induced knee osteoarthritis. After induction of experimental osteoarthritis by intra-articular injection of collagenase, adult New Zealand white rabbits (n = 12) were divided into 3 groups. Group 1 (control group) received 0.3 ml phosphate buffered saline into the right knee joint. Group 2 received 0.3 ml cross-linked hyaluronic acid (33 mg/ml) into the right knee joint. Group 3 received a mixture of 0.15 ml cross-linked hyaluronic acid (33 mg/ml), 0.05 ml ropivacaine hydrochloride 1 % and 0.1 ml triamcinolone acetonide (10 mg/ml) into the right knee joint. Intra-articular injections were given 4 weeks after first collagenase injection and were administered once a week for 3 weeks. Gross pathology and histological evaluation of rabbits' knee joints were performed after 16 weeks following initial collagenase injection. Histological analysis of sections of right knee joints at lesion sites showed a significant decrease in Mankin's score in groups treated with hyaluronic acid alone or in combination with ropivacaine hydrochloride and triamcinolone acetonide versus control group (p hyaluronic acid, alone or in combination with ropivacaine hydrochloride and triamcinolone acetonide, produces a significant improvement in knee articular cartilage degeneration in a rabbit model of collagenase-induced osteoarthritis.

    To investigate the clinical, cytological, and histopathological adverse effects of intra-articularly injected botulinum toxin A in dogs and to study whether the toxin spreads from the joint after the injection. A longitudinal, placebo-controlled, randomized clinical trial was conducted with six healthy laboratory Beagle dogs. Stifle joints were randomized to receive either 30 IU of onabotulinum toxin A or placebo in a 1:1 ratio. Adverse effects and spread of the toxin were examined by evaluating dynamic and static weight-bearing of the injected limbs, by assessing painless range of motion and pain on palpation of joints, and by performing synovial fluid analysis, neurological examination, and electrophysiological recordings at different examination time-points in a 12-week period after the injections. The dogs were then euthanized and autopsy and histopathological examination of joint structures and adjacent muscles and nerves were performed. Intra-articular botulinum toxin A did not cause local weakness or injection site pain. Instead, static weight-bearing and painless range of motion of stifle joints decreased in the placebo limbs. No clinically significant abnormalities associated with intra-articular botulinum toxin A were detected in the neurological examinations. Electrophysiological recordings showed low compound muscle action potentials in two dogs in the botulinum toxin A-injected limb. No significant changes were detected in the synovial fluid. Autopsy and histopathological examination of the joint and adjacent muscles and nerves did not reveal histopathological adverse effects of the toxin. Intra-articular botulinum toxin A does not produce significant clinical, cytological, or histopathological adverse effects in healthy dogs. Based on the electrophysiological recordings, the toxin may spread from the joint, but its clinical impact seems to be low.

    Using a systematic review, we investigated whether there is an increased risk of post-operative infection in patients who have received an intra-articular corticosteroid injection to the hip for osteoarthritis prior to total hip arthroplasty (THA). Studies dealing with an intra-articular corticosteroid injection to the hip and infection following subsequent THA were identified from databases for the period between 1990 to 2013. Retrieved articles were independently assessed for their methodological quality. A total of nine studies met the inclusion criteria. Two recommended against a steroid injection prior to THA and seven found no risk with an injection. No prospective controlled trials were identified. Most studies were retrospective. Lack of information about the methodology was a consistent flaw. The literature in this area is scarce and the evidence is weak. Most studies were retrospective, and confounding factors were poorly defined or not addressed. There is thus currently insufficient evidence to conclude that an intra-articular corticosteroid injection administered prior to THA increases the rate of infection. High quality, multicentre randomised trials are needed to address this issue. Cite this article: Bone Joint J 2016;98-B:1027-35. ©2016 The British Editorial Society of Bone & Joint Surgery.

    The purpose of this meta-analysis was to compare the efficacy and safety of single-dose intra-articular bupivacaine plus morphine versus bupivacaine alone for pain management following arthroscopic knee surgery. A comprehensive literature search was conducted to identify randomized controlled trials that used single-dose intra-articular bupivacaine plus morphine and bupivacaine alone for post-operative pain, using MEDLINE (1966-2014), Cochrane Library and EMBASE databases. The weighted mean difference (WMD), relative risk (RR) and their corresponding 95 % confidence intervals (CIs) were calculated using RevMan statistical software. A total of twenty-nine trials (n = 1167) were included. The post-operative visual analog scale (VAS) pain score of the bupivacaine plus morphine group compared with the bupivacaine alone group was significantly lower (WMD -1.15, 95 % CI -1.67 to -0.63, p bupivacaine plus morphine was shown to be significantly better than bupivacaine alone at relieving post-operative pain after arthroscopic knee surgery without increasing the short-term side effects. Routine use of single-dose intra-articular bupivacaine plus morphine is an effective way for pain management after arthroscopic knee surgery. II.

    Early post-operative exercise and weight-bearing activities are found to improve the functional recovery of patients with displaced intra-articular calcaneal fractures (DIACFs). We hypothesized that early functional exercise after surgery might have a secondary reduction effect on the subtalar joint, in particular the smaller fracture fragments that were not fixed firmly. A prospective study was conducted to verify this hypothesis. From December 2012 to September 2013, patients with unilateral DIACFs were enrolled and received a treatment consisting of percutaneous leverage and minimally invasive fixation. After surgery, patients in the study group started exercising on days two to three, using partial weight bearing starting week three, and full weight bearing starting week 12. Patients in the control group followed a conventional post-operative protocol of partial weight bearing after week six and full weight bearing after the bone healed. Computed tomography (CT) scanning was performed at post-operative day one, week four, week eight, and week 12 to reconstruct coronal, sagittal, and axial images, on which the maximal residual displacements of the fractures were measured. Function was evaluated using the American Orthopaedic Foot and Ankle Society (AOFAS) scoring scale at the 12th post-operative month. Twenty-eight patients in the study group and 32 in the control group were followed up for more than 12 months; their data were collected and used for the final analysis. Repeated-measures analysis of variance (ANOVA) of the maximal residual displacements of the fracture measured on CT images revealed significant differences between the study and the control groups. There were interaction effects between group and time point. Except for the first time point, the differences between the groups at all studied time points were significant. In the study group, the differences between all studied time points were significant. Strong correlations were observed between

    Full Text Available Abstract Background Temporomandibular joint (TMJ arthritis in children causes alterations in craniomandibular growth. This abnormal growth may be prevented by an early anti-inflammatory intervention. We have previously shown that intra-articular (IA corticosteroid reduces TMJ inflammation, but causes concurrent mandibular growth inhibition in young rabbits. Blockage of TNF-α has already proven its efficacy in children with juvenile idiopathic arthritis not responding to standard therapy. In this paper we evaluate the effect of IA etanercept compared to subcutaneous etanercept in antigen-induced TMJ-arthritis in rabbits on histological changes using histomorphometry and stereology. This article presents the data and discussion on the anti-inflammatory effects of systemic and IA etanercept. In Part II the data on the effects of systemic and IA etanercept on facial growth are presented. Methods Forty-two rabbits (10 weeks old pre-sensitized with ovalbumin and locally induced inflammation in the temporomandibular joints were divided into three groups: a placebo group receiving IA saline injections in both joints one week after arthritis induction (n = 14, an IA etanercept group receiving 0.1 mg/kg etanercept per joint one week after arthritis induction (n = 14 and a systemic etanercept group receiving 0.8 mg/kg etanercept weekly throughout the 12-week study (n = 14. Arthritis was maintained by giving four inductions three weeks apart. Additional IA saline or etanercept injections were also given one week after the re-inductions. Histomorphometric and unbiased stereological methods (optical fractionator were used to assess and estimate the inflammation in the joints. Results The histomorphometry showed synovial proliferation in all groups. The plasma cell count obtained by the optical fractionator was significantly reduced when treating with systemic etanercept but not with IA etanercept. Semi-quantitative assessments of synovial proliferation and

    Intra-articular bupivacaine hydrochloride (HCl) infusion catheters and periarticular injections of liposomal bupivacaine are often used as postoperative local anesthetics. The purpose of this study was to compare the efficacies of these local anesthetics following total knee arthroplasty. This study was a superiority trial with a randomized, controlled, double-blinded design. Patients were randomly assigned to either delivery of bupivacaine HCl by the ON-Q* Pain Relief System pump (n = 96) or by an injection of Exparel (liposomal bupivacaine) (n = 104). The primary outcome of this study was cumulative narcotic consumption on postoperative days 0 through 3. Narcotic consumption data were collected retrospectively from in-hospital records while patients were in the hospital. Following discharge, narcotic consumption data were gathered from patient surveys, as were secondary outcomes measures. We did not identify greater narcotic use in the ON-Q* group compared with the Exparel group (p = 0.641). The mean difference between the groups was 0.5 morphine equivalent (95% confidence interval [CI] = -1.7 to +2.8), with the ON-Q* group consuming an average 10.4 morphine equivalents (95% CI = 8.7 to 12.0) compared with 10.9 (95% CI = 9.3 to 12.5) in the Exparel group. There were no significant differences between groups with regard to any of the secondary measures of pain with the exception of pain while walking and pain with physical therapy (p = 0.019 and p = 0.010, respectively), both of which showed an approximately 1-point difference in favor of the ON-Q* group on a visual analog scale (VAS). There were also no differences in the postoperative side effects, including nausea, constipation, or vomiting, or in the rates of study-related complications, patient satisfaction, or length of hospital stay. Exparel did not have superior efficacy compared with the ON-Q* Pain Relief System as reflected by narcotic consumption, our primary outcome. There were small significant

    Background: Knee osteoarthritis (OA) is an incurable joint disorder, representing a major public health issue. Among options for symptom control, viscosupplementation with hyaluronic acid (HA) had established usefulness in pain and function improvement of the knee. However, it is not clear which form of HA yields better results. Material and Methods:We compared two HA preparations with high (HMW) or low molecular weight (LMW) in terms of pain control and function improvement using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and the visual analog scale (VAS) score in patients with knee OA. During 2013, 80 patients were enrolled in this prospective, double-blind, randomized study. Each patient received a weekly injection of either preparation with a total of five injections for the LMW group and three for the HMW group. They were evaluated at baseline, five weeks, three months and one year after treatment. Results: In both groups, HA treatment resulted in significant improvement in pain and function that begun immediately after treatment and lasted for one year. However when compared with each other, HMW and LMW groups were comparable in mean WOMAC, and VAS score at each time point. Neither preparation can interrupt disease progression as radiological findings remained constant during follow-up. Conclusions: Intra-articular injections using HMW or LMW HA can improve stiffness, joint function and pain in patients suffering from knee OA. However, no clear benefit seems to exist between the two preparations and neither can slow disease progression. Hippokratia 2016, 20(1): 26-31 PMID:27895439

    The purpose of this study was to compare the functional outcomes, psychological impact, and complication rates associated with external fixation and volar or dorsal plating in relation to the functional parameters following treatment of intra-articular fractures of the distal radius (IFDR) in patients older than 65 years. We hypothesized that using volar or dorsal plating would improve functional outcomes, but that it would be associated with more complications and equivalent functional outcomes when compared with the external fixation group. A total of 123 consecutive patients suffering from IFDR were recruited into the study. The patients were measured for clinical, radiological, and psychosocial functioning outcomes and were followed up after 1 week and 3, 6 and 12 months. After 3 months, the plating group had better pronation (P=0.001), supination, (P=0.047) and extension (P=0.043) scores. These differences were somewhat attenuated by 6 months and disappeared at 1 year. The plating group had a greater occurrence of wound infection (P=0.043), tendonitis, (P=0.024) and additional surgery compared with the external fixation group. The only TNO-AZL Adult Quality of Life scores in the plating group that were lower than those in the external fixation group were in the “gross motor” category (walking upstairs, bending over, walking 500 yards; P=0.023). Internal fixation was more advantageous than external fixation in the early rehabilitation period; after 1 year the outcomes were similar. The plating group showed significantly higher levels of wound infection and tendonitis and had a greater need for additional surgeries. PMID:27408765

    Orthobiologics such as autologous conditioned serum (ACS) are often used to treat joint disease in horses. Because ACS is generated from the horse's own blood, any medication administered at the time of preparation would likely be present in stored ACS, which could lead to an inadvertent positive drug test following intra-articular (IA) injection. The main objective of this study was to determine if ACS prepared from firocoxib positive horses could result in detectable plasma concentrations of the drug following IA injection. Firocoxib was administered to six horses at 0.1mg/kg PO twice at a 24h interval. Blood was obtained at 4h following the second dose and transferred to a separate syringe (Arthrex IRAP II) for ACS preparation. Plasma and ACS concentrations of firocoxib were analysed by liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS). When horses were confirmed firocoxib negative, 7.5mL of ACS was injected into both tarsocrural joints. Blood samples were collected at 0, 4, 8, 12, 24, and 48h, and firocoxib concentration was measured. Mean (±standard error of the mean, SEM) plasma concentration of firocoxib 4h following the second dose was 33.3±4.72ng/mL. Mean (±SEM) firocoxib concentration in ACS was 35.4±4.47ng/mL. Fourteen days following the second and last dose of firocoxib, mean plasma concentration was below the lower limit of detection (LOD=1ng/mL) in all horses. Following IA injection of ACS, plasma concentrations of firocoxib remained below LOD at all times in all horses. ACS generated from horses with therapeutic plasma concentrations of firocoxib did not contain sufficient firocoxib to lead to a positive plasma drug test following IA administration.

    Full Text Available Abstract Background This work aimed to study the homing evidence and the reparative effect of mesenchymal stem cells (MSCs in the healing process of induced osteoarthritis in experimental animal model (donkeys. Methods Twenty-seven donkeys were equally divided into 3 groups based on the observation period after induction of arthritis (3, 6 and 9 weeks to achieve different degrees of osteoarthritis. Each group was subdivided into three subgroups of three animals each based on the follow-up period (1, 2 and 6 months after treatment. The induction was done through intra-articular (IA injection of 2 ml of Amphotericin-B in both carpal joints. MSCs were harvested in a separate procedure, labeled with green fluorescent protein (GFP using monster GFP vector and suspended in hyaluronic acid for IA injection. Treatment approaches consisted of cell-treatment using MSCs suspended in 3 ml of hyaluronic acid (HA for the right carpal joint; and using the same amount of (HA but without MSCs for the left contralateral carpal joint to serve as a control. Animals were assessed clinically and radiologically before and after treatment. Synovial fluid was also evaluated. Histopathologically; articular cartilage structural changes, reduction of articular cartilage matrix staining, osteophyte formation, and subchondral bone plate thickening were graded. Data was summarized using median and percentile for scores of histopathologic grading. Comparison between groups was done using non-parametric Mann Whitney test. Results The reparative effect of MSCs was significant both clinically and radiologically in all treated groups (P Conclusions Homing was confirmed by the incorporation of injected GFP-labeled MSCs within the repaired newly formed cartilage. Significant recovery proves that the use of IA injection of autologous MSCs is a viable and a practical option for treating different degrees of osteoarthritis.

    Meniscus and cartilage lesions have been reported to be prevalent during delayed reconstruction of anterior cruciate ligament (ACL) injuries. Relatively, little work has been done exploring the influence of patient age on this relationship. The purpose of this study is to determine whether the effect of time from ACL injury to reconstruction on the prevalence of associated meniscal and chondral injury is influenced by patient age. It was hypothesized that patients in whom the time from ACL injury to reconstruction exceeds 12 weeks will exhibit an increased prevalence of medial compartment pathology relative to those reconstructed within 12 weeks of injury in patients of all ages. Data detailing time from ACL injury to reconstruction and the prevalence of intra-articular findings were obtained in 311 of 489 consecutive patients undergoing primary isolated ACL reconstruction. Patients were divided into two groups based on whether the time from ACL injury to reconstruction was time from ACL injury to reconstruction exceeded 12 weeks. The prevalence of lateral meniscal injury did not increase with increasing time ACL injury to surgery. Among patients aged 22 years and under, there was no increase in the prevalence of intra-articular pathology in any compartment in the late reconstruction group. In contrast, among patients over the age of 22, there was a significant increase in the prevalence of medial chondral injury (p = 0.042) in the late reconstruction group. The prevalence of injuries to the meniscus and articular cartilage in the medial compartment of the knee is increased with increasing time from ACL injury to reconstruction. This relationship may vary depending on patient age. Patients over the age of 22 exhibit a higher prevalence of intra-articular injury with delayed reconstruction, while no such differences are noted among younger patients.

The cationic NPs consisting of PLGA, Eudragit RL, and polyvinyl alcohol were fabricated by solvent evaporation technique. The NPs were 170.1 nm in size, with a zeta potential of 21.3 mV in phosphate-buffered saline. Hyperspectral imaging (CytoViva® revealed the formation of the micrometer-sized filamentous aggregates upon admixing, due to electrostatic interaction between NPs and the polysaccharides. NPs loaded with a fluorescent probe (1,1'-dioctadecyl-3,3,3',3' tetramethylindotricarbocyanine iodide, DiR displayed a significantly improved retention time in the knee joint, with over 50% preservation of the fluorescent signal 28 days after injection. When DiR solution was injected intra-articularly, the fluorescence levels rapidly decreased to 30% of the initial concentration within 3 days in mice. From these findings, we suggest that PLGA-based cationic NPs could be a promising tool for prolonged delivery of therapeutic agents in joints selectively.Keywords: PLGA, Eudragit RL, hyaluronic acid, cationic nanoparticles, intra-articular injection, electrostatic interaction

    Full Text Available Introduction: The purpose of this study was to investigate whether intra-articular injection of synovium-derived mesenchymal stem cells (SD MSCs with low molecular weight hyaluronic acid (HA could promote regeneration of massive cartilage in rabbits. Material and methods: The SD MSCs were harvested from the knees of 10 Flemish giant rabbits, expanded in culture, and characterized. A reproducible 4-mm cylindrical defect was created in the intercondylar groove area using a kit for the mosaic chondroplasty of femoral condyle COR (De Puy, Mitek. The defect was made within the cartilage layer without destruction of subchondral bone. Two weeks after the cartilage defect, SD MSCs (2 × 106 cell/0.15 ml were suspended in 0.5% low molecular weight HA (0.15 ml and injected into the left knee, and HA solution (0.30 ml alone was placed into the right knee. Cartilage regeneration in the experimental and control groups were evaluated by macroscopically and histologically at 10, 30, and 60 days. Results: On day 10, after intra-articular injection of SD MSCs, we observed an early process of cartilage regeneration in the defect area. Histological studies revealed that cartilage defect was covered by a thin layer of spindle-shaped undifferentiated cells and proliferated chodroblasts. In contrast, an injection of HA did not induce reparation of cartilage in the defect area. At 30 days, macroscopic observation showed that the size of cartilage defect after SD MSC injection was significantly smaller than after HA injection. Histological score was also better in the MSC- treated intercondylar defect. At 60 days after MSC treatment, cartilage defect was nearly nonexistent and looked similar to an intact cartilage. Conclusion: Thus, intra-articular injection of SD MSCs can adhere to the defect in the intercondylar area, and promote cartilage regeneration in rabbits.

    The study aim was to compare the efficacy and safety of ultrasound-guided intra-articular injections of hyaluronic acid and betamethasone in the management of patients with osteoarthritis of the thumb. Eighty-eight evaluable patients diagnosed with osteoarthritis of the thumb (Kellgren-Lawrence grade II-III) received ultrasound-guided intra-articular treatment with hyaluronic acid (48) or betamethasone (40). In total, 3 local injections were scheduled at 7-day intervals. Assessments were performed at baseline and at 7, 14, 30, 90, and 180 days. In both study groups, the pain Visual Analogue Scale and Functional Index for Hand Osteoarthritis scores decreased significantly during follow-up compared to baseline. There were no significant differences between the groups. However, at 90 days, the functional score showed a trend towards greater clinical improvement in the hyaluronic acid group (P 0.071). A subanalysis of patients with Functional Index score≥5 and Visual Analogue Scale score≥3 at baseline showed a significantly higher median functionality score in the hyaluronic acid group (P 0.005 at 90 days and P 0.020 at 180 days). Further limiting analysis to a baseline pain score≥5 showed significantly greater improvement in functionality score (P 0.004 at 180 days), which was already apparent after the second intra-articular injection at 14 days (P 0.028). In this patient subset, the mean pain score also improved significantly at 180 days (P 0.02). Both hyaluronic acid and betamethasone were effective and well-tolerated for the management of rhizarthrosis. Hyaluronic acid was more effective over time and more efficiently improved functionality and pain in patients with more severe symptoms. Copyright © 2014 Société française de rhumatologie.

    Our purpose was to evaluate the effectiveness of intra-articular injections of hyaluronic acid (HA) into immobilized joints for reducing rigidity and formation of joint adhesions following surgery and prolonged joint immobilization. Twenty-four New Zealand white rabbits were randomly divided into experimental (n = 12) and control groups (n = 12). A model of knee injury was created in the right hind leg, and external plaster fixation was performed for 8 weeks. The experimental and control groups received weekly intra-articular injections of 0.3 mL HA solution or normal saline, respectively, in the knee joint. The degree of adhesions, range of motion (ROM), and collagen content of the synovium of the knee joint were observed after 8 weeks. At the end of 8 weeks, the experimental compared with control group had significantly higher mean ROM (70.3° ± 11.1° vs. 54.6° ± 11.2°, respectively; P = 0.002) and mean adhesion score. The experimental group compared with the control group had significantly lower mean adhesion score (2.2 ± 0.9 vs. 3.1 ± 0.7, respectively; P = 0.012) and collagen content (32.4 ± 4.7 vs. 39.0 ± 4.2 μg/mg, P = 0.001). In a rabbit model of knee injury, intra-articular injection of HA decreased adhesion formation and collagen content and increased ROM after prolonged immobilization. These results indicate that HA may be clinically useful to prevent adhesions and improve joint mobility in patients who require joint immobilization for up to 8 weeks.

    To quantify the amount of the extra-articular long head of the biceps tendon (LHBT) seen during intra-articular shoulder arthroscopy by pulling the tendon into the joint with a probe through an anterior portal while viewing through a standard posterior portal. Intra-articular shoulder arthroscopy was performed on 10 forequarter cadaveric specimens. The extra-articular portion of the LHBT was evaluated by pulling the tendon into the joint with an arthroscopic probe inserted through an anterior portal. The tendon was marked at the pulley insertion on the humerus with a vascular clip before and after the tendon was pulled into the joint. An open deltopectoral approach was performed, and the amount of extra-articular tendon visualized was calculated as an absolute amount and in relation to nearby anatomic structures. An additional 1.9 cm (range, 1.4 to 2.6 cm) of extra-articular LHBT was viewed by pulling the tendon into the joint with an arthroscopic probe through an anterior portal during shoulder arthroscopy. This represented 30.8% of the extra-articular portion of the tendon, 47.7% of tendon in the bicipital groove, and 76.3% of the tendon that lies under the area from the pulley insertion to the distal edge of the transverse humeral ligament. During intra-articular shoulder arthroscopy, the extra-articular portion of the LHBT is incompletely visualized by pulling the tendon into the joint with a probe placed through an anterior portal while viewing through a standard posterior portal. An additional extra-articular portion of the LHBT may be viewed by pulling the tendon into the joint with an arthroscopic probe during shoulder arthroscopy.

    Full Text Available BACKGROUND AND OBJECTIVES: In this study, the aim was to compare postoperative analgesia effects of the administration of ultrasound-guided interscalene brachial plexus block and intra-articular bupivacaine carried out with bupivacaine. METHODS: In the first group of patients 20 mL 0.25% bupivacaine and ultrasound-guided interscalene brachial plexus block (ISPB were applied, while 20 mL 0.25% bupivacaine was given via intra-articular (IA administration to the second group patients after surgery. Patients in the third group were considered the control group and no block was performed. Patient-controlled analgesia (PCA with morphine was used in all three groups for postoperative analgesia. RESULTS: In the ISPB group, morphine consumption in the periods between 0-4, 6-12 and 12-24 postoperative hours and total consumption within 24 h was lower than in the other two groups. Morphine consumption in the IA group was lower than in the control group in the period from 0 to 6 h and the same was true for total morphine consumption in 24 h. Postoperative VASr scores in the ISPB group were lower than both of the other groups in the first 2 h and lower than the control group in the 4th and 6th hours (p < 0.05. In the IA group, VASr and VASm scores in the 2nd, 4th and 6th hours were lower than in the control group (p < 0.05. CONCLUSION: Interscalene brachial plexus block was found to be more effective than intra-articular local anesthetic injection for postoperative analgesia.

    Currently, administration of Botulinum toxin Type A (BoNT/A) to treat arthritic pain has promising efficacy in clinical research. However, the mechanisms underlying anti-neurogenic inflammation mediated by BoNT/A remains unclear. The aim of this study was to demonstrate the effectiveness in macro and micro levels and to explore the causal mechanism of BoNT/A. Wistar rats (n = 60) were injected with 50ul complete Freund's adjuvant (CFA) in the left ankle joint capsule to establish a model of chronic monoarthritis. Pain behaviour (Evoked pain assessment) and infrared thermal imaging testing were performed at the macroscopic level to assess the effectiveness of analgesia and anti-inflammation. Western blotting and immunofluorescence staining were used at the microscopic level in an attempt to determine the mechanisms of anti-nociceptive or anti-inflammatory effects of BoNT/A. Additionally, hematoxylin-eosin staining was also used to visualise the cartilage and the synovial degenerative conditions of arthritis. By comparing the outcome of the evoked pain test and immunofluorescence staining, there was a significant improvement in BoNT/A compared with the normal saline (NS) injected control group. In addition, thermal variations showed that the temperature of ipsilateral ankle joint increased between 1 and 2 weeks following injection of CFA, but decreased after 3 weeks (still above the contralateral side). However, the temperature showed no difference between the BoNT/A group and NS group after treatment. The expression of IL-1β or TNF-α in the ankle synovial tissue was significantly decreased in the BoNT/A group compared to the NS group (p < 0.05). Based on the HE assessment, cartilage degeneration and infiltration of inflammatory cells in the BoNT/A group was alleviated compared to the NS group after treatment. In conclusion, we proposed the hypothesis that intra-articular BoNT/A administration does play an important role in anti-neurogenic inflammation. The

    To compare the lateral mortise and anterior midline approaches to fluoroscopically guided tibiotalar joint injections with respect to successful intra-articular needle placement, fluoroscopy time, radiation dose, and dose area product (DAP). This retrospective study was IRB-approved and HIPAA-compliant. 498 fluoroscopically guided tibiotalar joint injections were performed or supervised by one of nine staff radiologists from 11/1/2010-12/31/2013. The injection approach was determined by operator preference. Images were reviewed on a PACS workstation to determine the injection approach (lateral mortise versus anterior midline) and to confirm intra-articular needle placement. Fluoroscopy time (minutes), radiation dose (mGy), and DAP (μGy-m{sup 2}) were recorded and compared using the student's t-test (fluoroscopy time) or the Wilcoxon rank sum test (radiation dose and DAP). There were 246 lateral mortise injections and 252 anterior midline injections. Two lateral mortise injections were excluded from further analysis because no contrast was administered. Intra-articular location of the needle tip was documented in 242/244 lateral mortise injections and 252/252 anterior midline injections. Mean fluoroscopy time was shorter for the lateral mortise group than the anterior midline group (0.7 ± 0.5 min versus 1.2 ± 0.8 min, P < 0.0001). Mean radiation dose and DAP were less for the lateral mortise group than the anterior midline group (2.1 ± 3.7 mGy versus 2.5 ± 3.5 mGy, P = 0.04; 11.5 ± 15.3 μGy-m{sup 2} versus 13.5 ± 17.3 μGy-m{sup 2}, P = 0.006). Both injection approaches resulted in nearly 100 % rates of intra-articular needle placement, but the lateral mortise approach used approximately 40 % less fluoroscopy time and delivered 15 % lower radiation dose and DAP to the patient.

    Objectives The purpose of this study was to compare the efficacy and safety of a single-dose intra-articular morphine plus bupivacaine versus morphine alone in patients undergoing arthroscopic knee surgery. Methods Randomized controlled trials comparing a combination of morphine and bupivacaine with morphine alone injected intra-articularly in the management of pain after knee arthrocopic surgery were retrieved (up to August 10, 2014) from MEDLINE, the Cochrane Library and Embase databases. The weighted mean difference (WMD), relative risk (RR) and their corresponding 95% confidence intervals (CIs) were calculated using RevMan statistical software. Results Thirteen randomized controlled trials were included. Statistically significant differences were observed with regard to the VAS values during the immediate period (0-2h) (WMD -1.16; 95% CI -2.01 to -0.31; p = 0.007) and the time to first request for rescue analgesia (WMD = 2.05; 95% CI 0.19 to 3.92; p = 0.03). However, there was no significant difference in the VAS pain score during the early period (2-6h) (WMD -0.36; 95% CI -1.13 to 0.41; p = 0.35), the late period (6-48h) (WMD 0.11; 95% CI -0.40 to 0.63; p = 0.67), and the number of patients requiring supplementary analgesia (RR = 0.78; 95% CI 0.57 to 1.05; p = 0.10). In addition, systematic review showed that intra-articular morphine plus bupivacaine would not increase the incidence of adverse effects compared with morphine alone. Conclusion The present study suggested that the administration of single-dose intra-articular morphine plus bupivacaine provided better pain relief during the immediate period (0-2h), and lengthened the time interval before the first request for analgesic rescue without increasing the short-term side effects when compared with morphine alone.

    BACKGROUND: There is conflicting evidence regarding the use of intra-articular lignocaine injection for the closed manual reduction of acute anterior shoulder dislocations. A systematic review may help cohere the conflicting evidence. OBJECTIVES: To compare the clinical efficacy and safety of intra-articular lignocaine and intravenous analgesia (with or without sedation) for reduction of acute anterior shoulder dislocation. SEARCH STRATEGY: We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 1), MEDLINE (1950 to March 2010), and EMBASE (1980 to March 2010). We searched Current Controlled Trials metaRegister of Clinical Trials (compiled by Current Science) (March 2010). We imposed no language restriction. SELECTION CRITERIA: Randomized controlled trials comparing intra-articular lignocaine (IAL) with intravenous analgesia with or without sedation (IVAS) in adults aged 18 years and over for reduction of acute anterior shoulder dislocation. DATA COLLECTION AND ANALYSIS: Two authors independently assessed trial quality and extracted data. Where possible, data were pooled and relative risks (RR) and mean differences (MD), each with 95% confidence intervals (CI), were computed using the Cochrane Review Manager statistical package (RevMan). MAIN RESULTS: Of 1041 publications obtained from the search strategy, we examined nine studies. Four studies were excluded, and five studies with 211 participants were eligible for inclusion. There was no difference in the immediate success rate of IAL when compared with IVAS in the closed manual reduction of acute anterior shoulder dislocation (RR 0.95; 95% CI 0.83 to 1.10). There were significantly fewer adverse effects associated with IAL compared with IVAS (RR 0.16; 95% CI 0.06 to 0.43). The mean time spent in the emergency department was significantly less with IAL compared with IVAS (MD 109.46 minutes; 95% CI 84.60 to 134.32). One trial reported significantly less time for

    Full Text Available Abstract Background Although intra-articular hyaluronic acid is well established as a treatment for osteoarthritis of the knee, its use in hip osteoarthritis is not based on large randomized controlled trials. There is a need for more rigorously designed studies on hip osteoarthritis treatment as this subject is still very much under debate. Methods/Design Randomized, controlled trial with a three-armed, parallel-group design. Approximately 315 patients complying with the inclusion and exclusion criteria will be randomized into one of the following treatment groups: infiltration of the hip joint with hyaluronic acid, with a corticosteroid or with 0.125% bupivacaine. The following outcome measure instruments will be assessed at baseline, i.e. before the intra-articular injection of one of the study products, and then again at six weeks, 3 and 6 months after the initial injection: Pain (100 mm VAS, Harris Hip Score and HOOS, patient assessment of their clinical status (worse, stable or better then at the time of enrollment and intake of pain rescue medication (number per week. In addition patients will be asked if they have complications/adverse events. The six-month follow-up period for all patients will begin on the date the first injection is administered. Discussion This randomized, controlled, three-arm study will hopefully provide robust information on two of the intra-articular treatments used in hip osteoarthritis, in comparison to bupivacaine.

    Autophagy is an essential cellular homeostasis mechanism that was found to be compromised in aging and osteoarthritis (OA) cartilage. Previous studies showed that resveratrol can effectively regulate autophagy in other cells. The purpose of this study was to determine whether the chondroprotective effect of resveratrol was related to chondrocyte autophagy and to elucidate underlying mechanisms. OA model was induced by destabilization of the medial meniscus (DMM) in 10-week-old male mice. OA mice were treated with resveratrol with/without 3-MA for 8 weeks beginning 4 weeks after surgery. The local intra-articular injection of resveratrol delayed articular cartilage degradation in DMM-induced OA by OARSI scoring systems and Safranin O-fast green. Resveratrol treatment increased Unc-51-like kinase1, Beclin1, microtubule-associated protein light chain 3, hypoxia inducible factor-1α, phosphorylated AMPK, collagen-2A1, Aggrecan expressions, but decreased hypoxia inducible factor-2α, phosphorylated mTOR, matrix metalloproteinases13 and a disintegrin and metalloproteinase with thrombospondin motifs 5 expressions. The effects of resveratrol were obviously blunted by 3-MA except HIF and AMPK. These findings indicate that resveratrol intra-articular injection delayed articular cartilage degeneration and promoted chondrocyte autophagy in an experimental model of surgical DMM-induced OA, in part via balancing HIF-1α and HIF-2α expressions and thereby regulating AMPK/mTOR signaling pathway.

    To study and compare the clinical outcomes of open reduction and internal fixation via extensile L-shape incision and limited open reduction via the sinus tarsi approach using the medial distraction technique for intra-articular calcaneal fractures. We performed a retrospective review of 65 intra-articular calcaneal fractures treated operatively between March 2012 and February 2015. Patients were divided into two groups: 28 were in the sinus tarsi approach group and 37 were in the extensile lateral approach group. All patients were asked to return for a research visit that included radiography and clinical evaluation. The postoperative function was evaluated using the ankle and hindfoot score of the American Orthopaedic Foot and Ankle Society (AOFAS) and the visual analogue scale (VAS). No significant difference was found in demographics between the two groups. The corrected value of the calcaneal varus angle between the two groups is statistically significant (P articular calcaneal fractures could reduce the incidence of wound complications effectively, and the medial distraction technique is helpful for correcting the calcaneus varus deformity. © 2017 Chinese Orthopaedic Association and John Wiley & Sons Australia, Ltd.

    To compare the effectiveness and safety of intra-articular injections of autologous expanded mesenchymal stromal stem cells alone (MSCs), or in combination with platelet-rich plasma (MSCs + PRP), in patients with knee osteoarthritis. Eighteen patients (57.6 ± 9.6 years) with radiographic symptomatic knee osteoarthritis (Dejour grades II-IV) were randomized to receive intra-articular injections of MSCs (n = 9) or MSCs + PRP (n = 9). Injections were performed 2-3 weeks after bone marrow aspiration (± 80-100 ml) which was obtained from both posterior iliac crests. The Knee Injury and Osteoarthritis Outcome Score (KOOS) improved significantly throughout the 12 months for both groups (p injections of expanded MSCs alone or in combination with PRP are safe and have a beneficial effect on symptoms in patients with symptomatic knee osteoarthritis. Adding PRP to the MSCs injections did not provide additional benefit. These results are encouraging and support the recommendation of this minimally invasive procedure in patients with knee osteoarthritis, without requiring hospitalization. The CFU-F results may be used as reference for future research. Prospective cohort study, Level II.

    Acetabular dysplasia is one of the most common sources of hip arthritis. With the recent innovation in hip arthroscopy, the question has been raised whether arthroscopy can be used to treat dysplastic hip conditions. The purposes of this systematic review are (i) describe the prevalence of intra-articular pathologies and (ii) report the outcomes of dysplastic hip treatment with hip arthroscopy as a sole treatment. Medical databases were searched for articles including arthroscopic findings and treatment of dysplastic hip with predetermined criteria. PubMed, Ovid database and CINAHL (Cumulative Index to Nursing and Allied Health Literature) were searched up until 7 January 2015. Two reviewers independently assess the eligibility of retrieved studies using titles, abstracts and full-text articles. Thirteen studies were eligible to be included for the systematic review. Overall, labral tear was the most common pathology with a prevalence rate of 77.3%. All of the four studies describing arthroscopic treatment for only borderline dysplasia reported favorable outcome. With regard to more severely dysplastic hips, two out of three studies reported acceptable outcomes while one study reported negative results. This review indicates that intra-articular pathology is commonly observed in symptomatic dysplastic hips with a labral tear being the most common pathology. Arthroscopic treatment of borderline dysplasia could provide benefits whereas treatment of more dysplastic hips is controversial. Nevertheless, there is a lack of evidence for using arthroscopy alone in hips with a center edge angle <20°. Level IV, systematic review of Level IV studies. PMID:27583155

The TXA patients had significantly fewer requirements for allogeneic blood transfusion (p application, maximum TXA concentration at the site of application, no danger associated with administration of a higher TXA dose and minimal TXA resorption into the circulation. On the other hand, there are no exact instructions for an effective and safe topical application of TXA and some authors are concerned that a coagulum arising after TXA application might affect soft tissue behaviour (healing, swelling, rehabilitation) or result in infection. CONCLUSIONS The study showed the efficacy and safety of topical TXA administration resulting in lower peri-operative bleeding, fewer blood transfusion requirements and higher haemoglobin levels after TKA. The patients treated with TXA had less knee swelling, lower incidence of haematomas and used fewer analgesic drugs in the early post-operative period. The economic benefit is also worth considering. In agreement with the recent literature, it is suggested to add topical TXA application to the recommended procedures for TKA surgery.

    Controversy exits over the role of Böhler's angle in assessing the injury severity of displaced intra-articular calcaneal fractures and predicting the functional outcome following internal fixation. This study aims to investigate whether a correlation exists between Böhler's angle and the injury severity of displaced calcaneal fractures, and between surgical improvement of Böhler's angle and functional outcome. Patients treated operatively for unilateral closed displaced intra-articular calcaneal fractures from January 1, 2004 to March 31, 2008 were identified. The Böhler's angles of both calcaneus were measured, and the measurement of the uninjured foot was used as its normal control. The difference in the value of Böhler's angle measured preoperatively or postoperatively between the angle of the injured foot and that of the contralateral calcaneus were calculated, respectively. The change in Böhler's angle by ratio was calculated by dividing the difference value of Böhler's angle between bilateral calcaneus by its normal control. The injury severity was assessed according to Sanders classification. The functional outcomes were assessed using American Orthopaedic Foot & Ankle Society hindfoot scores. 274 patients were included into the study with a mean follow-up duration of 71 months. According to Sanders classification, the fracture pattern included 105 type II, 121 type III and 48 type IV fractures. According to American Orthopaedic Foot & Ankle Society hindfoot scoring system, the excellent, good, fair and poor results were achieved in 104, 132, 27, and 11 patients, respectively. The preoperative Böhler's angle, difference value of Böhler's angle between bilateral calcaneus, and change in Böhler's angle by ratio each has a significant correlation with Sanders classification (rs=-0.178, P=0.003; rs=-0.174, P=0.004; rs=-0.172, P=0.005, respectively), however, is not correlated with functional outcome individually.

    Lumbar facet joint syndrome is currently suggested to be a main source of axial low back pain, and a large portion of axial low back pain is caused by disorders in lumbar facet joints. Intra-articular injection is one of the most common treatment methods in the early clinical application. Therefore, we attempt to seek a new injectable material, autologous platelet rich plasma (PRP), to treat lumbar facet syndrome, as well as to assess its therapeutic effectiveness and safety. A prospective clinic evaluation. The outpatient clinic of a single academic medical center. Total 19 patients with lumbar facet joint syndrome (8 men, 11 women; mean ages: 52.53 ± 6.79 years, range: 38 - 62 years) were enrolled to receive lumbar facet joint injection with autologous PRP under x-ray fluoroscopic control. Patients were followed up immediately, at one week, one month, 2 months, and 3 months following treatment, and the elements of this analysis included low back pain visual analogue scale (VAS) at rest and during flexion, Roland-Morris Disability Questionnaire (RMQ), Oswestry Disability Index (ODI), and modified MacNab criteria for the pain relief. All the 19 patients completed the intra-articular injections with autologous PRP successfully. At one week after treatment, low back pain reduced significantly compared with prior to treatment both at rest and during flexion. The outcomes were assessed as "good" or "excellent" for 9 patients (47.37%) immediately after treatment, 14 patients (73.68%) at one week, 15 patients (78.95%) at one month, 15 patients (78.95%) at 2 months, and 15 patients (78.95%) at 3 months. Statistically significant differences were observed based on RMQ and a more than 10% improvement in lumbar functional capacity was observed based on ODI between pre-treatment and post-treatment. In addition, there were no severe relevant complications during the whole process of injection and follow-up period. A control group and the curative effect observations with

    Recently, combined intra-articular tranexamic acid (IA-TXA) injection with clamping drain method showed efficacy for blood loss and transfusion reduction in total knee replacement (TKR). However, until now, none of previous studies revealed the effect of this technique on pharmacokinetics, coagulation, and fibrinolysis. An experimental study was conducted, during 2011-2012, in 30 patients undergoing unilateral TKR. Patients received IA-TXA application and then were allocated into six groups regarding clamping drain duration (2-, 4-, 6-, 8-, 10-, and 12-hours). Blood and drainage fluid were collected to measure tranexamic acid (TXA) level and related coagulation and fibrinolytic markers. Postoperative complication was followed for one year. There was no significant difference of serum TXA level at 2 hour and 24 hour among groups (p application in TKR with prolonged clamping drain method is a safe and effective blood conservative technique with only minimal systemic absorption and without significant increase in systemic absorption over time.

    The disease modifying potential of osteoarthritis therapies are of increasing interest, including their effects on delaying total knee replacement (TKR). To date, there have been no studies to determine the effect of LMWF-5A, a novel anti-inflammatory compound derived from human serum albumin, on delaying TKR. We evaluated time to TKR three years after patients participated in a randomized trial of three intra-articular injections of LMWF-5A or saline. Patients were contacted via last known phone number and were asked to participate in a short nine item telephone questionnaire; verbal consent was obtained. The primary endpoint was incidence of TKR (%). In total, 39 of 45 patients responded (87% response rate). The overall incidence of TKR was 38.5% (15/39). TKR rates were higher in patients with more severe osteoarthritis defined by Kellgren-Lawrence grade 4, compared to patients with moderate osteoarthritis defined by Kellgren-Lawrence grade 3 (56% vs. 26%, p  = 0.06). Overall, there were no differences in TKR rates by treatment arm (39% LMWF-5A vs. 38% saline, p  = 0.92). In the severe osteoarthritis subset ( n  = 16), treatment with LMWF-5A resulted in a lower incidence of TKR compared to saline vehicle arm (40% vs. 83%, p  = 0.15). TKR rates were significantly lower with LMWF-5A in patients who responded to treatment (14% with LMWF-5A, vs. 100% with saline, p  = 0.03). This study demonstrates significant delays in TKR for patients with severe osteoarthritis treated with LMWF-5A, suggesting that LMWF-5A has the potential to provide structure modifying/preserving therapy in this population.

    The aim of this review was to analyze the available evidence on the clinical application of this biological approach for the injective treatment of cartilage lesions and joint degeneration, together with preclinical studies to support the rationale for the use of platelet concentrates, to shed some light and give indications on what to treat and what to expect from intra-articular injections of platelet-rich plasma (PRP). All in vitro, in vivo preclinical and clinical studies on PRP injective treatment in the English language concerning the effect of PRP on cartilage, synovial tissue, menisci, and mesenchymal stem cells were considered. A systematic review on the PubMed database was performed using the following words: (platelet-rich plasma or PRP or platelet concentrate or platelet lysate or platelet supernatant) and (cartilage or chondrocytes or synoviocytes or menisci or mesenchymal stem cells). Fifty-nine articles met the inclusion criteria: 26 were in vitro, 9 were in vivo, 2 were both in vivo and in vitro, and 22 were clinical studies. The analysis showed an increasing number of published studies over time. Preclinical evidence supports the use of PRP injections that might promote a favourable environment for joint tissues healing. Only a few high-quality clinical trials have been published, which showed a clinical improvement limited over time and mainly documented in younger patients not affected by advanced knee degeneration. Besides the limits and sometimes controversial findings, the preclinical literature shows an overall support toward this PRP application. An intra-articular injection does not just target cartilage; instead, PRP might influence the entire joint environment, leading to a short-term clinical improvement. Many biological variables might influence the clinical outcome and have to be studied to optimize PRP injective treatment of cartilage degeneration and osteoarthritis.

    There are many alternatives for post-operative pain relief in patients who have had general anaesthesia. The aim of this study was to evaluate the efficacy of intra-articular bupivacaine + morphine and bupivacaine + tenoxicam applications in post-operative pain control in patients undergoing knee arthroscopy with general anaesthesia. This was a prospective study. Standard anaesthesia procedures were applied to each patient, and the 240 patients chosen at random were then divided into two groups. Each group received a different combination of drugs for this double-blind study. The first group (group A: 120 patients) received 0.5% bupivacaine 100 mg + tenoxicam 20 mg (22 ml); the second group (group B) received 0.5% bupivacaine 100 mg + morphine 2 mg (22 ml); both groups received their drugs at the end of the intra-articular operation before tourniquet deflation. Before the operation, patients were asked about their post-operative pain at particular periods over the following 24 hours using the visual analogue scale (VAS) and the numeric rating scale (NRS). An additional analgaesic requirement and possible side effects were also recorded. Group A patients needed analgaesics sooner after operation than patients in group B. In Group B, VAS and NRS values were statistically higher compared with group A at the 12th hour. There were also fewer side effects seen in group A versus group B. Effective and reliable results were obtained in post-operative pain control in bupivacaine added to the morphine or tenoxicam groups following arthroscopic meniscectomy. In the tenoxicam group, patients reported less pain, fewer side effects and less need for analgesics at 12 hours after the operation. level 1, therapeutic, randomised, multicentric study.

    Introduction: In cases of patients with ligament hiperlaxity with rupture of ACL, the use of a BTB graft is recommended for its reconstruction. Our job consists of the clinical and functional assessment of a group of 10 patients with ligament laxaty according to Beighton scale, who, after surgery for ACL rupture with BTB technique, suffered a rupture of the plastic. For its reconstruction a combination of intra-articular and extra-articular techniques was used with a BTB graft in the contralateral knee, associated with a modified Lemaire technique. Methods: The series consists of 10 patients, male, average age of 24.2 years, amateur athletes, operated for a second time in March, 2011 and November, 2013, with a minimum follow-up of 24 months. They were evaluated before surgery and 24 months after surgery based on Lysholm scale, IKDC evaluation form and a physical exam (Lachman - Pivot Shift). Results: After surgery, the average in Lysholm scale was of 87.6 and 86.3 for the IKDC subjetive form. In the physical exam, 8 patients showed Lachman 1+, while none of the patients showed Pivot Shift positive. 7 patients were able to return to their usual sport activities. As a postoperative disadvantage, 6 patients reported pain in the external face of the knee in the first 6 months. And 4 patients reported a subjetive loss of full extension that did not interfere with their sport activities. Conclusion: Based on our experience and literature, we believe that the combination of both techniques, intra-articular (BTB) and extra-articular (Lemaire), is a good alternative for patients with ligament laxaty, providing positive clinical and functional results.

    Several studies have shown that blockade of colony stimulating factor-1 (CSF-1) or its receptor (CSF-1R) inhibits disease progression in rodent models of rheumatoid arthritis (RA); however, the role of the CSF-1/CSF-1R pathway in RA-induced pain and functional deficits has not been studied. Thus, we examined the effect of chronic intra-articular administration of a monoclonal anti-CSF-1R antibody (AFS98) on spontaneous pain, knee edema and functional disabilities in mice with arthritis. Unilateral arthritis was produced by multiple injections of complete Freund's adjuvant (CFA) into the right knee joint of adult male ICR mice. CFA-injected mice were then treated twice weekly from day 10 until day 25 with anti-CSF-1R antibody (3 and 10 μg/5 μL per joint), isotype control (rat IgG 10 μg/5 μL per joint) or PBS (5 μl/joint). Knee edema, spontaneous flinching, vertical rearing and horizontal exploratory activity were assessed at different days. Additionally, counts of peripheral leukocytes and body weight were measured to evaluate general health status. Intra-articular treatment with anti-CSF-1R antibody significantly increased horizontal exploratory activity and vertical rearing as well as reduced spontaneous flinching behavior and knee edema as compared to CFA-induced arthritis mice treated with PBS. Treatment with this antibody neither significantly affect mouse body weight nor the number of peripheral leukocytes. These results suggest that blockade of CSF-1R at the initial injury site (joint) could represent a therapeutic alternative for improving the functional disabilities and attenuating pain and inflammation in patients with RA.

    Context: Low back pain (LBP) is a complex and disabling condition, and its treatment becomes a challenge. Aims: The aim of our study was to assess the clinical outcome of plasma rich in growth factors (PRGF-Endoret) infiltrations (one intradiscal, one intra-articular facet, and one transforaminal epidural injection) under fluoroscopic guidance-control in patients with chronic LBP. PRGF-Endoret which has been shown to be an efficient treatment to reduce joint pain. Settings and Design: The study was designed as an observational retrospective pilot study. Eighty-six patients with a history of chronic LBP and degenerative disease of the lumbar spine who met inclusion and exclusion criteria were recruited between December 2010 and January 2012. Subjects and Methods: One intradiscal, one intra-articular facet, and one transforaminal epidural injection of PRGF-Endoret under fluoroscopic guidance-control were carried out in 86 patients with chronic LBP in the operating theater setting. Statistical Analysis Used: Descriptive statistics were performed using absolute and relative frequency distributions for qualitative variables and mean values and standard deviations for quantitative variables. The nonparametric Friedman statistical test was used to determine the possible differences between baseline and different follow-up time points on pain reduction after treatment. Results: Pain assessment was determined using a visual analog scale (VAS) at the first visit before (baseline) and after the procedure at 1, 3, and 6 months. The pain reduction after the PRGF-Endoret injections showed a statistically significant drop from 8.4 ± 1.1 before the treatment to 4 ± 2.6, 1.7 ± 2.3, and 0.8 ± 1.7 at 1, 3, and 6 months after the treatment, respectively, with respect to all the time evaluations (P PRGF in patients with chronic LBP resulted in significant pain reduction assessed by VAS.

    The aim of this study was to evaluate the impact of intra-articular corticosteroid injection (IACI) of depot betamethasone at the knee joint on insulin resistance (IR). Patients with type 2 diabetes, non-insulin treated, with painful osteoarthritis of the knee were requested to participate in our study. After consent, demographic, clinical, and laboratory parameters were documented in addition to fasting blood glucose (FBG) and fasting blood insulin levels just prior to IACI of 1 mL of depot betamethasone. Fasting blood glucose and fasting blood insulin levels were repeated the next day following the IACI and 8 days later. Age- and sex-matched group of patients with type 2 diabetes from the same clinic were recruited as a control group (case-control study). Insulin resistance was calculated using Homeostasis Model Assessment-Insulin Resistance. Mann-Whitney U test, χ test, and Wilcoxon signed rank tests were used for statistical analysis. Eleven patients were recruited in the patients' group and 10 patients in the control group. Median FBG in the patients' group at baseline was 148 ± 51 mg/dL, and median IR was 5.12 ± 2.46. One day following the IACI, median FBG level was 247 ± 104 mg/dL (P = 0.004, compared with baseline), with median IR of 20.8 ± 7.01 (P = 0.0039). The median ratios of blood glucose and IR 1 day following the IACI compared with baseline were 1.7 and 4.1, respectively. Eight days following the IACI, mean FBG and IR levels were not significantly different from baseline. Intra-articular corticosteroid injection of betamethasone at the knee joint among patients with diabetes was associated with a significant increase in IR levels compared with baseline levels, 1 day following the injection. The mean percentage of increase in IR was higher than that for FBG levels.

    Implantation of PAMPS/PDMAAm double-network (DN) gel can induce hyaline cartilage regeneration in the osteochondral defect. However, it is a problem that the volume of the regenerated cartilage tissue is gradually reduced at 12 weeks. This study investigated whether intra-articular administration of hyaluronic acid (HA) increases the volume of the cartilage regenerated with the DN gel at 12 weeks. A total of 48 rabbits were used in this study. A cylindrical osteochondral defect created in the bilateral femoral trochlea was treated with DN gel (Group DN) or left without any implantation (Group C). In both Groups, we injected 1.0 mL of HA in the left knee, and 1.0 mL of saline solution in the right knee. Quantitative histological evaluations were performed at 2, 4, and 12 weeks, and PCR analysis was performed at 2 and 4 weeks after surgery. In Group DN, the proteoglycan-rich area was significantly greater in the HA-injected knees than in the saline-injected knees at 12 weeks (P = 0.0247), and expression of type 2 collagen, aggrecan, and Sox9 mRNAs was significantly greater in the HA-injected knees than in the saline-injected knees at 2 weeks (P = 0.0475, P = 0.0257, P = 0.0222, respectively). The intra-articular administration of HA significantly enhanced these gene expression at 2 weeks and significantly increased the volume of the hyaline cartilage regenerated by implantation of a DN gel at 12 weeks. This information is important to develop an additional method to increase the volume of the hyaline cartilage tissue in a potential cartilage regeneration strategy using the DN gel.

    Despite regular inhalation of beta-agonists, topical steroids and anticholinergic aerosols and the achievement of therapeutic blood levels of theophylline, some asthmatics have rapidly fluctuating levels of peak flow measurements throughout the day. Often little or no improvement is obtained with larger doses of corticosteroids. Before embarking on more intense drug therapy, attention should be paid to conscientious adherence to the prescribed regimen and avoidance of aspirin and tartrazine, as well as to exposure to allergens such as those associated with household pets. A number of newer therapeutic options are related to the use of air jet or ultrasonic nebulizers, that allow liquid forms of inhalation agents to be taken slowly in the home environment. In this regard, combination therapy with a beta-agonist and the anticholinergic ipratropium has been shown to have bronchodilating properties superior to either agent used alone. Secondly, sodium cromoglycate in its liquid form appears to have bronchodilator properties; taken on a regular basis, four times per day, it appears to have a steroid-sparing effect. Two alternatives are available for increasing the intensity of corticosteroid therapy, other than by prolonged, high-dose prednisone. The first is that of high-dose inhaled beclomethasone (up to 2000 micrograms/day) using the 250 micrograms/puff inhaler. The second is that of intravenous therapy with methylprednisolone, recently shown to have lung permeability superior to that of prednisolone. Office patients can be treated with occasional or even regular 'pulse' doses of methylprednisolone, an approach that is now finding acceptance in the management of the inflammatory alveolitides.

    Diagnosis of intra-articular lesions in children based on clinical examination and MRI is particularly challenging. To evaluate the diagnostic performance of MRI and pre-surgical evaluation of the knee in pediatric patients relative to arthroscopic evaluation as the gold standard. We report diagnoses frequently missed or inaccurately diagnosed pre-operatively. We conducted a retrospective review of MRI and pre-surgical evaluation in children and adolescents ages 1-17 years who were treated by knee arthroscopy during a 21/2-year period. All MRIs were reviewed by a pediatric radiologist blinded to clinical findings. Pediatric orthopedic clinic notes were reviewed for pre-surgical evaluation (based on physical exam, radiograph, MR images and radiologist's MRI report). Arthroscopic findings were used as the gold standard. We calculated the percentages of diagnoses at arthroscopy missed on both MRI and pre-surgical evaluation. Diagnostic accuracy between children and adolescents and in patients with one pathological lesion vs. those with >1 lesion was analyzed. We performed a second review of MR images of the missed or over-called MRI diagnoses with knowledge of arthroscopic findings. We included 178 children and adolescents. The most common diagnoses missed on MRI or pre-surgical evaluation but found at arthroscopy were: discoid meniscus (8/30, or 26.7% of cases); lateral meniscal tears (15/80, or 18.8% of cases); intra-articular loose bodies (5/36, or 13.9% of cases), and osteochondral injuries (9/73, or 12.3% of cases). Overall diagnostic accuracy of MRI and pre-surgical evaluation was 92.7% and 95.3%, respectively. No significant difference in diagnostic accuracy between children and adolescents was observed. When multiple intra-articular lesions were present, lateral meniscal tears were more likely to be inaccurately diagnosed (missed or over-called) on both MRI (P = 0.009) and pre-surgical evaluation (P < 0.001).

    Full Text Available In clinical practice viscosupplementation with hyaluronic acid (HA is common for the treatment of degenerative osteoarthritis (OA. Both molecular weight and concentration of HA have significant impact on its rheological properties, which in turn affects its therapeutic effects. The objective of this study is to evaluate the effectiveness of a double HA preparation for the treatment of knee osteoarthritis with respect to pain reduction, joint function improvement and concomitant medication consumption reduction. One thousand and fourteen patients (521 males and 693 females with a mean age of 62.4 years old, suffering from OA of the knee, were enrolled into this study. All patients received two intra-articular injections one week apart and a third injection one month after the second one. Concomitant medication was recorded and evaluated at follow up visits. Evaluation was performed at baseline, day 30 and day 180, on several parameters: knee pain by visual analog scale (VAS 0-10 cm, Lequesne Index, and consumption of concomitant medications including non-steroidal anti-inflammatory drugs, analgesics and chondoprotective supplementations. A statistically significant reduction in pain VAS score was recorded at D30 (38.01±17.68; P<0.01 before the third injection, and D180 (25.91±15.33; P<0.01 check-points comparing to baseline (67.12±15.99. Similarly, remarkable reduction in Lequesne Index was shown at D30 (5.91±4.01; P<0.01 in 1214 patients before the third injection, and D180 (3.59±3.45; P<0.01 (with 938 patients when compared to the baseline (11.60±5.13. Patients also consumed less concomitant medications after the treatment course. The beneficial effects were maintained for up to six months. Intra-articular injection of a double HA preparation of low molecular weight and high molecular weight of different concentrations was well tolerated, and generated satisfactory results in terms of pain control, joint function improvement and

    Rotator cuff tear is a leading etiology of shoulder pain and disability. Surgical treatment is indicated in patients with persistent pain who fail a trial of non-surgical treatment. Pain reduction following rotator cuff repair, particularly within the first 24-48 h, is a major concern to both doctors and patients. This study aimed to compare the postoperative antinociceptive additive effects of pre-incisional intra-articular (IA) ketamine when combined with morphine with two times the dose of morphine or saline. In this prospective, randomized, double blind, controlled trial patients undergoing arthroscopic rotator cuff tear repair (ARCR) under general anesthesia were enrolled. Patients were randomly assigned to one of the three intervention groups. Twenty minutes prior to incision, morphine (20 mg/10 ml), ketamine (50 mg + morphine 10 mg/10 ml), or saline (0.9 % 10 ml) (n = 15/group), were administered to all patients. First 24 h postoperative analgesia consisted of intravenous patient controlled analgesia (IV-PCA) morphine and oral rescue paracetamol 1000 mg or oxycodone 5 mg. 24-h, 2-week and 3-month patient rated pain numeric rating scale (NRS) and analgesics consumption were documented. Patients' demographic and perioperative data were similar among all groups. The 24-h and the 2-week NRSs were significantly (p pain in the first 2 weeks after arthroscopic rotator cuff repair. Further research is warranted to elucidate the optimal timing and dosing of IA ketamine and morphine for postoperative analgesic effects.

    To assess the efficacy of intra-articular hyaluronic acid (HA) injections and exercise-based rehabilitation (EBR) programme, administered as isolated or integrated for the treatment of knee osteoarthritis. One hundred sixty-five patients affected by moderate degrees of knee OA were randomly divided into three groups. Group 1 (HA) underwent three HA injections (one every 2 weeks); group 2 (EBR) underwent 20 treatment sessions in a month of an individualized programme; and group 3 (HA + EBR) received both treatments simultaneously. Primary outcome was the Italian version of the Western Ontario and McMaster Universities (WOMAC) Osteoarthritis Index; secondary outcome was the evaluation of active range of movement (AROM). All patients were evaluated before and 1, 3 and 6 months after treatment. Significance was set at p injections and individualized rehabilitation programmes administered in isolation or in combination are effective in improving knee function and pain relief. The combined treatment showed the greatest pain relief at 1-month follow-up compared to either in isolation. Compared to the previous studies, this is the first study, which proposed an EBR programme tailored to the compartment of the knee joint most involved in the degenerative process. I.

    Full Text Available Background. Recently, intra-articular tranexamic acid (IA-TXA application has become a popular method for perioperative blood loss (PBL reduction in total knee replacement (TKR. Nevertheless, through our knowledge, no previous studies had shown the correlation perioperative factors and the risk of excessive PBL or need of blood transfusion (BT after IA-TXA. Materials and Methods. A retrospective study was conducted in patients underwent 299 primary TKRs, using IA-TXA, during 2-year period (2013-2014. Patient’s characteristic and perioperative data were reviewed and collected. PBL was measured as total hemoglobin loss (THL, estimated total blood loss (ETBL, and drainage volume per kg (DV/kg. Excessive PBL was defined as PBL that exceeded 90th percentile. Results. From multivariate analysis, low preoperative hemoglobin (Hb level and body mass index (BMI were the significant predictors of postoperative BT (p<0.0001 and 0.003, resp.. Excessive THL significant associated with preoperative Hb (p<0.0001. Excessive ETBL significantly associated with preoperative Hb, height, preoperative range-of-motion, and creatinine clearance (p<0.05 all. Low BMI and large prosthesis size were the significant predictors of excessive DV/kg (p=0.0001 and 0.002, resp.. Conclusions. Low preoperative Hb and BMI were the significant risks of postoperative transfusion after TKR with IA-TXA. Moreover, multiple perioperative factors could result in higher PBL.

    Substantial weakness of the quadriceps muscles is typically observed in patients with arthritis. This is partly due to ongoing neural inhibition that prevents the quadriceps from being fully activated. Evidence from animal studies suggests enhanced flexion reflex excitability may contribute to this weakness. This prospective observational study examined the effects of joint aspiration and intra-articular corticosteroid injection on flexion reflex excitability, quadriceps muscle strength and knee pain in individuals with knee synovitis. Sixteen patients with chronic arthritis and clinically active synovitis of the knee participated in this study. Knee pain flexion reflex threshold, and quadriceps peak torque were measured at baseline, immediately after knee joint aspiration alone and 5 ± 2 and 15 ± 2 days after knee joint aspiration and the injection of 40 mg of methylprednisolone acetate. Compared to baseline, knee pain was significantly reduced 5 (p = 0.001) and 15 days (p = 0.009) post intervention. Flexion reflex threshold increased immediately after joint aspiration (p = 0.009) and 5 (p = 0.01) and 15 days (p = 0.002) post intervention. Quadriceps peak torque increased immediately after joint aspiration (p = 0.004) and 5 (p = 0.001) and 15 days (p knee synovitis.

    To evaluate the prevalence of injuries of the scapholunate and lunotriquetral interosseous ligaments (SLIL, LTIL) as well as the triangular fibrocartilage complex (TFCC) in intra-articular distal radius fractures (iaDRF). Two hundred and thirty-three patients with acute iaDRF underwent MDCT arthrography. The SLIL and LTIL were described as normal, partially or completely ruptured. Major injuries of the SLIL were defined as completely ruptured dorsal segments, those of the LTIL as completely ruptured palmar segments. The TFCC was judged as normal or injured. Interobserver variability was calculated. Injury findings were correlated with the types of iaDRF (AO classification). In 159 patients (68.2 %), no SLIL injuries were seen. Minor SLIL injuries were detected in 54 patients (23.2 %), major injuries in 20 patients (8.6 %). No correlation was found between the presence of SLIL lesions and the types of iaDRF. Minor LTIL injuries were seen in 23 patients (9.9 %), major injuries in only 5 patients (2.2 %). The TFCC was altered in 141 patients (60.5 %). Interobserver variability was high for MDCT arthrography in assessing SLIL and TFC lesions, and fair for LTIL lesions. In iaDRF, prevalence of major injuries of the most relevant SLIL is about 9 % as evaluated with CT arthrography. (orig.)

    The study aims to evaluate whether the analgesic effect of intra-articular (IA) route of xylazine administered to horses following arthroscopic surgery is due to a local or a systemic action. Two connected studies were performed. In the first, 1 mg/kg b.w. of xylazine was injected IA, and blood samples were taken to assess drug systemic absorption. In addition, systemic effects of the drug (sedation, ataxia or reduction of respiratory and cardiac rate) were registered. Control horses injected with saline IA were included in the study to exclude the influence of anaesthesia in the occurrence of these manifestations. In the second study, 1 mg/kg b.w. of xylazine was administered intravenously (i.v.) in healthy horses. Blood samples were collected to determine the concentrations of xylazine, and the same signs of systemic effects of the drug were recorded. By correlating these parameters, a systemic 'no effect' concentration was defined. Pharmacokinetic data after IA administration resulted in some xylazine absorption (bioavailability equal to 58.12%) with values above the systemic 'no effect' concentration. The occurrence of some signs related to systemic effects in horses receiving IA xylazine was significant compared with horses receiving saline. In conclusion, a systemic action of the drug after IA administration cannot be excluded. © 2014 John Wiley & Sons Ltd.

    Full Text Available Background. Recently, combined intra-articular tranexamic acid (IA-TXA injection with clamping drain method showed efficacy for blood loss and transfusion reduction in total knee replacement (TKR. However, until now, none of previous studies revealed the effect of this technique on pharmacokinetics, coagulation, and fibrinolysis. Materials and Methods. An experimental study was conducted, during 2011-2012, in 30 patients undergoing unilateral TKR. Patients received IA-TXA application and then were allocated into six groups regarding clamping drain duration (2-, 4-, 6-, 8-, 10-, and 12-hours. Blood and drainage fluid were collected to measure tranexamic acid (TXA level and related coagulation and fibrinolytic markers. Postoperative complication was followed for one year. Results. There was no significant difference of serum TXA level at 2 hour and 24 hour among groups (p<0.05. Serum TXA level at time of clamp release was significantly different among groups with the highest level at 2 hour (p<0.0001. There was no significant difference of TXA level in drainage fluid, postoperative blood loss, blood transfusion, and postoperative complications (p<0.05.  Conclusions. Low-dose IA-TXA application in TKR with prolonged clamping drain method is a safe and effective blood conservative technique with only minimal systemic absorption and without significant increase in systemic absorption over time.

    Our aim was to compare the effect of sinus tarsi approach (STA) vs extensile lateral approach (ELA) for treatment of closed displaced intra-articular calcaneal fractures (DIACF) is still being debated. A thorough research was carried out in the MEDLINE, EMBASE and Cochrane library databases from inception to December 2016. Only prospective or retrospective comparative studies were selected in this meta-analysis. Two independent reviewers conducted literature search, data extraction and quality assessment. The primary outcomes were anatomical restoration and prevalence of complications. Secondary outcomes included operation time and functional recovery. Four randomized controlled trials involving 326 patients and three cohort studies involving 206 patients were included. STA technique for DIACFs led to a decline in both operation time and incidence of complications. There were no significant differences between the groups in American Orthopedic Foot and Ankle Society scores, nor changes in Böhler angle. This meta-analysis suggests that STA technique may reduce the operation time and incidence of complications. In conclusion, STA technique is reasonably an optimal choice for DIACF.

    2018-05-10

    The aim of this review is to explore the scientific rationale and evidence for a potential benefit of joint lavage followed by intra-articular injection of hyaluronic acid and/or corticosteroids in patients with severe hemophilic arthropathy of the knee (SHAK). Areas covered: This article is a narrative review of the evidence for potential benefits of joint lavage followed by intra-articular injection of hyaluronic acid and corticosteroids in SHAK compared with osteoarthritis of the knee in non-hemophilia patients. Expert commentary: Although some reports on hemophilic arthropathy with a low-grade of evidence seem to indicate a benefit of joint lavage followed by intra-articular injection of hyaluronic acid and/or corticosteroids in patients with SHAK, the short-lived improvements afforded by hyaluronic acid, and the doubtful benefits of corticosteroids and joint lavage in hemophilia, do not warrant their use in hemophilic patients. The scientific rationale of these procedures is poor and they are not recommended.

    The treatment of knee osteoarthritis with hyaluronic acid or corticosteroid injection has been widely used. The purpose of this study was to compare the efficacy of hyaluronic acid (hylan G-F 20) with triamcinolone acetonide as a single intra-articular injection for knee osteoarthritis. This study was a prospective, randomized, double-blind clinical trial. Participants with symptomatic knee osteoarthritis were recruited. They were randomized to receive a single-shot, intra-articular injection of either 6 mL of hylan G-F 20 or 6 mL of a solution comprising 1 mL of 40-mg triamcinolone acetonide and 5 mL of 1% lidocaine with epinephrine. The primary outcomes were knee pain severity, knee function, and range of motion at 6 months. Ninety-nine patients were assessed before injection and underwent a 6-month follow-up. Patients and evaluators were blinded. Multilevel regression models were used to estimate differences between the groups. At the 6-month follow-up, compared with patients who took hylan G-F 20, patients who took triamcinolone acetonide had similar improvement in knee pain, knee function, and range of motion. The difference in mean outcome scores between groups was, with regard to knee pain, a visual analog scale (VAS) score of 3 points (95% confidence interval [95% CI], -6 to 11 points); with regard to knee function, a modified Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) score of 0 points (95% CI, -8 to 6 points); and, with regard to range of motion, flexion of -1° (95% CI, -5° to 2°) and extension of 0° (95% CI, -0.5° to 0.5°). However, patients who took triamcinolone acetonide had better pain improvement from 24 hours until 1 week after injection; the mean difference between groups with regard to the VAS score was 12 points (95% CI, 5 to 20 points; p = 0.002) at 24 hours and 9 points (95% CI, 1 to 15 points; p = 0.018) at 1 week. At 2 weeks after injection, patients who took triamcinolone acetonide also had better knee

    Purpose: To identify and compare magnetic resonance imaging (MRI) characteristics, with and without intravenous contrast medium, of cavernous synovial hemangiomas and cystic synovial hyperplasia. Material and Methods: Four cases of cavernous synovial hemangioma and five of cystic synovial hyperplasia of the knee were studied retrospectively. The patients (5 F and 4 M; 15-25 years of age) all had long-standing knee pain. At clinical examination we observed elastic swelling and pain without significant joint effusion. The patients underwent conventional radiography and MRI without and following intravenous contrast medium before arthroscopic biopsy. Results: The radiographs were interpreted as negative in all patients. MRI examination without contrast medium revealed a similar multicystic appearance for both lesions. Following intravenous contrast agent administration, cavernous synovial hemangiomas demonstrated avid, rather homogenous enhancement, whereas cystic synovial hyperplasia demonstrated less intense, peripheral enhancement only. Arthroscopy with histological examination of the lesions confirmed the MRI diagnosis in every case. Conclusion: In our experience, cavernous synovial hemangioma and cystic synovial hyperplasia have a similar appearance on unenhanced MRI, but can be reliably differentiated on the basis of enhancement characteristics following intravenous contrast administration. Keywords: Cavernous synovial hemangioma; cystic synovial hyperplasia; knee; MRI

    Full Text Available The study deals with mechanical testing of newly developed material polyethylene terephtalate coated with polycaprolactone nanofibers in combination with biodagradable Hexalon ACL/PCL screws as a new possibility of intra-articular reinforcement of partially ruptured cranial cruciate ligament. Four groups of ex vivo models of pig stifle joints were prepared and tested: a model with intact CCL (group 1, a model with partial CCL rupture (group 2, a model with CCL rupture stabilized with 7 mm Mersilene® strip (group 3, and a model with CCL rupture stabilized with 5 mm PET/PCL biomaterial strip (group 4. The models were loaded in the standing angle of 100° and the maximum load (N and the shift (mm were monitored. The mean maximum peak power and the shift were 1266.0 ± 146.9 N and 13.7 ± 2.5 mm for group 1, and 1164.7 ± 228.2 N and 1 6.8 ± 3.3 mm for group 2, respectively. In all cases after reaching the maximum load, a tibial fracture occurred but never a CCL rupture. In groups 3 and 4, the initial fixation failure occurred in the mean values of 375.7 ± 81.5 and 360.4 ± 52.0 N, respectively, and with a bigger shift of 52.3 ± 11.9 mm and 39.4 ± 14.6 mm, respectively, compared to group 1. A critical point of failure was the anchoring in the bone. It can be concluded that the PET/PCL substitute in the ex vivo model has mechanically comparable properties with the clinically used Mersilene®, and based on its proven ability to carry stem cells it could be appropriate for partially ruptured CCL protection.

    Treatment for comminuted fracture dislocations of the proximal interphalangeal joint (pilon injuries) remains a challenge. We present our short term results of twelve pilon fracture dislocations treated by closed reduction and application of a distraction dynamic external fixator. The aim of the study was to assess the clinical outcomes and compare them to the original description by Hynes and Giddins. A cohort of 12 consecutive patients with pilon fracture of the proximal interphalangeal joint (comminuted fracture of the base of middle phalanx, longitudinally unstable with joint subluxation), were treated with this method over the study period. Data was collected by an independent observer at last follow-up appointment in the clinic. The outcome measures recorded were; level of residual pain, arc of motion, X-ray appearance, return to work and satisfaction with the procedure. The study group comprises of 7 male and 5 female patients at a mean age of 38.1 years (range 21-70 years). The average range of movement achieved was 13-87° at a mean follow-up of 16.4 weeks (Range 12-42 weeks). Early return to work, good pain relief and high level of patient satisfaction were achieved. No serious complication was noted during this period. We used the construct with slight modification of the original description and we feel this modification may help to reduce the pin site infection. We found the results reproducible and based on our experience we recommend this technique to treat these complex intra-articular fractures of base of middle phalanx.

    Purpose: To investigate and compare delayed gadolinium (Gd-DTPA)-enhanced magnetic resonance imaging (MRI) of cartilage (dGEMRIC) in the hip joint using intravenous (i.v.) or ultrasound-guided intra-articular (i.a.) Gd-DTPA injection. Material and Methods: In 10 patients (50% males, mean age 58 years) with clinical and radiographic hip osteoarthritis (OA; Kellgren score II-III), MRI of the hip was performed twice on a clinical 1.5T MR scanner: On day 1, before and 90-180 min after 0.3 mmol/kg body weight i.v. Gd-DTPA and, on day 8, 90-180 min after ultrasound-guided i.a. injection of a 4 mmol/l Gd-DTPA solution. Coronal STIR, coronal T1 fat-saturated spin-echo, and a cartilage-sensitive gradient-echo sequence (3D T1 SPGR) in the sagittal plane were applied. Results: Both the post-i.v. and post-i.a. Gd-DTPA images showed significantly higher signal-to-noise (SNR) and contrast-to-noise (CNR) in the joint cartilage compared to the non-enhanced images ( P <0.002). I.a. Gd-DTPA provided significantly higher SNR and CNR compared to i.v. Gd-DTPA ( P <0.01). Furthermore, a better delineation of the cartilage in the synovial/cartilage zone and of the chondral/subchondral border was observed. Conclusion: The dGEMRIC MRI method markedly improved delineation of hip joint cartilage compared to non-enhanced MRI. The i.a. Gd-DTPA provided the best cartilage delineation. dGEMRIC is a clinically applicable MRI method that may improve identification of early subtle cartilage damage and the accuracy of volume measurements of hip joint cartilage

    Summary Background Hip joint diseases are common in adult population and their prevalence increases with age. Osteoarthritis, rheumatoid arthritis and femoroacetabular impingement are the most common chronic diseases in the hip joint. Viscosupplementation with exogenous hyaluronic acid (HA) is one of the most widely used conservative treatment aiming to improve synovial fluid properties and to decrease pain. There is no global consensus on the type of HA, method of injection and frequency, or on its efficacy in hip joint. Methods We selected published data in English in the PubMed and Google Scholar electronic databases up to March 2016 about hyaluronic acid injections in hip disorders. Results 26 articles were included following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Conclusion There is a lack of standardization of HA injections for hip conditions. Our results suggest that this is the best conservative therapy before surgery and it can act on pain relief and function however there is no evidence to prove its ability to modify the morphological structure of the pathological hip and the natural history of the disease. There are few data about the use of HA in other hip disorders rather than osteoarthritis. The most relevant evidence seems to show the utility of HA injections in improving synovial inflammation, but only a few studies have been conducted. Level of evidence I. PMID:28066733

    Full Text Available Pharmaco-economic data on the management of knee osteoarthritis (OA with intra articular hyaluronic acid (IA HA viscosupplementation is limited. We contrasted IA HA with non-steroidal anti-inflammatory drugs (NSAIDs.Observational, prospective and multicenter study comparing treatments of knee OA costs and efficacy with either NSAIDs alone, or hyaluronic acid (Arthrum H 2%®, during a 6-month follow-up period. The investigators were pharmacists who recorded data on disease, drug consumption and healthcare circuit. Retrospectively, the 6-month period preceding inclusion was also studied, to ensure the comparability of groups.199 patients were analyzed in a NSAIDs group and 202 in an IA HA group. Any of the WOMAC sub-scores and the EQ-5D Quality of Life index were significantly improved in the IA HA group (p<0.0001 at 3 and 6 months. Clinical results were therefore in favor of the IA HA group. The total drug expenses per 6-month period were comparable before and after inclusion, €96 and €98 for NSAIDs group vs €94 and €101 for IA HA group, which indicates no evidence of additional cost from IA HA. For the active part of the population, the incidence of sick leave was lower in the IA HA group, indicating a better maintenance of patient activity. The overall expense on 12 months (6 months before and 6 months after inclusion for the national health insurance system was comparable for NSAIDs and IA HA groups: €528 and €526, respectively. The number of patients taking NSAIDs significantly decreased in IA HA group (from 100% at inclusion to 66% at 1-3 months and 44% at 4-6 months, but remained unchanged (100% during the follow-up period, in NSAIDs group.Treatment with IA HA did not generate additional cost for the national health insurance and was associated with a functional improvement of knee osteoarthritis and Quality of Life. The cost-utility analysis was in favor of IA HA, with a gain of QALY equivalent to half a month, after the 6

    The efficacy of oral steroid therapy for autoimmune pancreatitis (AIP) is well known, and oral prednisolone treatment is most usually commenced at 30-40 mg/day, but there have been few reports about comparative studies of oral steroid therapy and steroid pulse therapy as the initial treatment for AIP. We studied the clinical course and image findings to estimate the utility of steroid pulse therapy for AIP, comparing it with oral steroid therapy. Laboratory and image findings were assessed retrospectively in 11 patients who received steroid pulse therapy, and the findings were compared to those in 10 patients who received conventional oral steroid therapy. Change in pancreatic size showed no significant difference between the therapies after 2 weeks of treatment. Significant improvement of lower bile duct strictures after 2 weeks of treatment and that of immunoglobulin values within 6 months were shown with both therapies. However, steroid pulse therapy showed significant improvement of γ-guanosine triphosphate (GTP) in 2 weeks and of alanine aminotransferase (ALT) in 2 and 8 weeks, compared with oral steroid therapy. Moreover, there was one patient in whom the lower bile duct stricture was not improved by oral steroid therapy, but it did show improvement with steroid pulse therapy. Initial steroid pulse therapy is a beneficial alternative to oral steroid therapy for the improvement of bile duct lesions. In future, the accumulation of a larger number of patients receiving steroid pulse therapy is needed, and prospective studies will be required. (author)

    The aim of this study is to assess the effectiveness of Radiosynovectomy (RSV) using 177 Lu-labeled hydroxyapatite ( 177 Lu-HA) in the treatment of painful synovitis and recurrent joint effusion of knee joints in rheumatoid arthritis (RA). Ten patients, diagnosed with RA and suffering from chronic painful resistant synovitis of the knee joints were referred for RSV. The joints were treated with 333 ± 46 MBq of 177 Lu-HA particles administered intra-articularly. Monitoring of activity distribution was performed by static imaging of knee joint and whole-body gamma imaging. The patients were evaluated clinically before RSV and at 6 months after the treatment by considering the pain improvement from baseline values in terms of a 100-point visual analog scale (VAS), the improvement of knee flexibility and the pain remission during the night. RSV response was classified as poor (VAS < 25), fair (VAS ≥ 25-50), good (VAS ≥ 50-75) and excellent (VAS ≥ 75), with excellent and good results considered to be success, while fair and poor as failure and also by range of motion. Three phase bone scan (BS) was repeated after 6 months and changes in the second phase of BS3 were assessed visually, using a four-degree scale and in the third phase, semiquantitatively with J/B ratio to see the response. Biochemical analysis of C-reactive protein (CRP) and fibrinogen was repeated after 48 h, 4 and 24 weeks. In all 10 patients, no leakage of administered activity to nontarget organs was visible in the whole-body scan. Static scans of the joint at 1 month revealed complete retention of 177 Lu-HA in the joints. All patients showed decreased joint swelling and pains, resulting in increased joint motion after 6 months. The percentage of VAS improvement from baseline values was 79.5 ± 20.0% 6 months after RS and found to be significantly related to patients' age (P = 0.01) and duration of the disease (P = 0.03). Knees with Steinbrocker's Grades 0 and I responded better than

    Intra-articular platelet-rich plasma (PRP) injection has been found to be effective for treating osteoarthritis in patients from Western countries; however, the safety and efficacy of PRP have not been sufficiently investigated in Japanese patients. The present study aimed to evaluate the safety and feasibility of intra-articular PRP injection in Japanese patients with knee osteoarthritis. PRP without white blood cells was prepared using a single-spin centrifuge (PRGF-Endoret; BTI Biotechnology Institute, Vitoria, Spain). A 6-mL PRP volume was injected in the knee joint three times at 1 week intervals. All patients were prospectively evaluated before intervention and at 1, 3, and 6 months after the treatment. Adverse events, the Visual Analog Scale (VAS) pain score, Japanese Knee Osteoarthritis Measure (JKOM) score and Japanese Orthopedic Association score were evaluated. Ten patients (all women; average age, 60.6 years) were treated. Only minor adverse events after injection were noted, and symptoms resolved within 48 hours after the injection. The average VAS pain scores were 71.6 mm and 18.4 mm at baseline and the 6-month follow-up, respectively (P PRP injection likely represents a safe treatment option for Japanese patients with mild-to-moderate knee osteoarthritis, and has the potential to relieve pain for up to 6 months, but further study is needed to verify the efficacy.

    Introduction: Intra-articular hyaluronic acid (HA) is widely utilized in the treatment of knee osteoarthritis whereas platelet rich plasma (PRP) enhances the regeneration of articular cartilage. This study analyses the efficacy of HA and PRP in grade III and IV knee osteoarthritis. Methodology: This is a cross sectional study with retrospective review of 64 patients (101 knees) which includes 56 knees injected with HA+ PRP, and 45 knees with HA only. Results: During the post six months International Knee Documentation Committee (IKDC) evaluation, HA+PRP group showed marked improvement of 24.33 compared to 12.15 in HA group. Decrement in visual analogue score (VAS) in HA+PRP was 1.9 compared to 0.8 in HA group. Conclusion: We propose intra-articular HA and PRP injections as an optional treatment modality in Grade III and IV knee osteoarthritis in terms of functional outcome and pain control for up to six months when arthroplasty is not an option.

    Full Text Available Background: Superior labral anterior to posterior (SLAP lesions have been well described in the literature and are thought to be secondary to traction injuries to the biceps anchor and/or falls on the outstretched arm. The pulley has recently been described as a structure that aids in the prevention of biceps instability. The intra-articular subscapularis insertion (IASS has been noted to contribute to the robust nature of the medial sheath. The purpose of the study was to determine a potential correlation of SLAP lesions and pulley lesions with/without IASS lesions, (hereafter referred to as medial sheath as forces that can disrupt the biceps anchor and may also disrupt structures of the medial sheath or vice-versa. Materials and Methods: Three hundred and sixteen consecutive shoulder arthroscopies performed by one surgeon were reviewed retrospectively. Operative reports and arthroscopic pictures were carefully reviewed with particular attention paid to the labral and pulley pathology. Selection bias was noted as the author had never operated primarily for a Type 1 SLAP lesion. Following, however, and as such, the exclusion criteria, was a Type 1 SLAP. Results: There were a total of 30 SLAP lesions and a total of 126 medial sheath lesions. There were 13 patients who had both SLAP and medial sheath lesions. There were 17 patients who had a SLAP lesion without a medial sheath lesion. There were 96 medial sheath lesions without a SLAP. A comparison of rates between patients who had a medial sheath lesion with a SLAP and those who had a medial sheath lesion without a SLAP, for the 316 patients, and when tested with a Fisher exact test revealed that there was no statistical significance, P = 0.673. The prevalence of SLAP lesions in this population of 316 patients was 9.4%, Buford 1%, medial sheath lesions 39%, and SLAP and medial sheath lesions 4%. Interestingly, there were three Buford complexes, all associated with a SLAP and one Buford complex

    Full Text Available Background Tight control of severe rheumatoid arthritis (RA in patients with high disease activity, even when using biologics, is sometimes difficult using a treat-to-target strategy. Switching from one biologic to another is associated with lower efficacy than that in treatment-naive cases. We developed the K-method that involves simultaneous treatment with golimumab and intra-articular joint injection of triamcinolone acetonide (TA in patients undergoing switching of biologics. We performed this retrospective case–control study to investigate the efficacy of achieving an immediate treatment response using the K-method. Methods This study involved 20 patients with RA (control group, 10 patients; K-method group, 10 patients. Patients in the control group were switched to golimumab from other biologics without intra-articular injection of TA. The K-method involved injection of 1 mL of TA (40 mg/mL and 2 mL of 1% lidocaine hydrochloride into swollen or painful joints on the same day as golimumab treatment. A quick response one day after treatment was compared between the two groups according to the disease activity score 28 based on C-reactive protein (DAS28 CRP, clinical disease activity index (CDAI, simplified disease activity index (SDAI, European League Against Rheumatism (EULAR response, and remission rate. These parameters were investigated for 24 weeks. Results The K-method group showed significant improvements in DAS28 CRP, CDAI, and SDAI at one day, 12 weeks, and 24 weeks compared with the control group. The number of swollen and tender joints and the patient and doctor global visual analog scale scores were also significantly different between the two groups. The remission rates based on DAS28 CRP were 30% at one day, 50% at 12 weeks, and 60% at 24 weeks in the K-method group. The EULAR good/moderate response rates were 80% at one day, 90% at 12 weeks, and 90% at 24 weeks in the K-method group; however, these rates were only 10%, 40

    Although treatment of acute heart failure is based primarily on the administration of intravenous loop diuretics, evidence supporting this practice is still scarce and there is uncertainty about the optimal dose. The existence of a considerable percentage of patients refractory to diuretic therapy and worsening of renal failure associated with the use of these drugs, with possible implications for medium-term mortality, have prompted the search for more effective and safer alternatives. Extracorporeal purification techniques, such as ultrafiltration, have demonstrated efficacy, although their superiority is unclear, due to the possible adverse effects associated with the procedure. The use of low-dose dopamine is not superior to conventional diuretic therapy after the first few hours of treatment. Moreover, combination with furosemide and hypertonic saline could be a valid alternative for patients with refractory congestion and depressed ejection fraction and serum creatinine ≤ 2.5mg/dL, but further studies are needed before its widespread use. The use of tolvaptan may be an effective alternative in the short-term but its use may be limited by its price. There is still controversy about whether treatment with loop diuretics is associated with higher mortality in all groups of patients with HF exacerbations. These controversies should be clarified by future clinical trials. Copyright © 2014 Elsevier España, S.L. All rights reserved.

    Knee cartilage or osteochondral lesions are common and challenging injuries. To date, most symptomatic lesions warrant surgical treatment. We present two cases of patients with knee osteochondral defects treated with a one-step surgical procedure consisting of an autologous-based matrix composed of healthy hyaline cartilage chips, mixed plasma poor-rich in platelets clot, and plasma rich in growth factors (PRGF). Both patients returned to playing soccer at the preinjury activity level and demonstrated excellent defect filling in both magnetic resonance imaging and second-look arthroscopy (in one of them). The use of a clot of autologous plasma poor in platelets with healthy hyaline cartilage chips and intra-articular injection of plasma rich in platelets is an effective, easy, and cheap option to treat knee cartilage injuries in young and athletic patients.

    Full Text Available Introduction: Amiodarone as an antiarrhythmic medication is necessary in the prevention and treatment of malignant ventricular arrhythmias, however, it can induce thyroid dysfunction. Thyroid dysfunction may be either hypothyroidism or thyrotoxicosis, however, 50% of patients who have used amiodarone are euthyroid. Case report: A 27-year-old female patient, hospitalized at the Clinic for Endocrinology due to type 2 amiodarone-induced thyrotoxicosis. The patient had previously received amiodarone for two years. At age 25, the patient was diagnosed with dilated cardiomyopathy (EF 25%, EDD/ESD 56-57/47 mm with mild Ebstein’s anomaly, WPW Sy and recorded episodes of non-sustained VT. In order to reduce the risk of sudden death and prevent malignant ventricular arrhythmias, ICD-VR was implanted and amiodarone was prescribed. Treatment with propylthiouracil (PTU and dexamethasone was initiated after thyrotoxicosis was diagnosed. Three weeks after the introduction of PTU, hepatotoxicity was registered, thus the medication was discontinued. Thyrozol, which regulates the hepatotoxicity parameters, was introduced. Sodium perchlorate and glucocorticoid (per os, IV and intrathyroidal therapy was introduced. The treatment had lasted for fifty days and laboratory signs of thyrotoxicosis were still present, which is why a total of eight plasmapheresis sessions were performed. Each plasmapheresis resulted in a significant decrease in FT4 and a slight decrease in FT3. After seventy two days of treatment, an optimal hormonal status of the thyroid gland was established and total thyroidectomy was performed. Conclusion: Patient was treated for amiodarone-induced thyrotoxicosis (AIT type 2, which was resistant to conventional therapy for a long period of time. Successful treatment was achieved by applying plasmapheresis although the effect of perchlorate and glucocorticoids application cannot be disregarded.

    To investigate the effects of VitalStim therapy coupled with conventional swallowing training on recovery of post-stroke dysphagia, a total of 120 patients with post-stroke dysphagia were randomly and evenly divided into three groups: conventional swallowing therapy group, VitalStim therapy group, and VitalStim therapy plus conventional swallowing therapy group. Prior to and after the treatment, signals of surface electromyography (sEMG) of swallowing muscles were detected, swallowing function was evaluated by using the Standardized Swallowing Assessment (SSA) and Videofluoroscopic Swallowing Study (VFSS) tests, and swallowing-related quality of life (SWAL-QOL) was evaluated using the SWAL-QOL questionnaire. There were significant differences in sEMG value, SSA, VFSS, and SWAL-QOL scores in each group between prior to and after treatment. After 4-week treatment, sEMG value, SSA, VFSS and SWAL-QOL scores were significantly greater in the VitalStim therapy plus conventional swallowing training group than in the conventional swallowing training group and VitalStim therapy group, but no significant difference existed between conventional swallowing therapy group and VitalStim therapy group. It was concluded that VitalStim therapy coupled with conventional swallowing training was conducive to recovery of post-stroke dysphagia.

    Background and objectives: Knee osteoarthritis is the most common joint disease. We aimed to compare the efficacy and safety of intra-articular injection of a newly developed plasma rich in growth factor (PRGF) versus hyaluronic acid (HA) on pain and function of patients with knee osteoarthritis. Methods: In this single-blinded randomized clinical trial, patients with symptomatic osteoarthritis of knee were assigned to receive 2 intra-articular injections of our newly developed PRGF in 3 weeks or 3 weekly injections of HA. Our primary outcome was the mean change from baseline until 2 and 6 months post intervention in scores of visual analog scale, Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), and Lequesne index. We used analysis of variance for repeated-measures statistical test. Results: A total of 69 patients entered final analysis. The mean age of patients was 58.2 ± 7.41 years and 81.2% were women. In particular, total WOMAC index decreased from 42.9 ± 13.51 to 26.8 ± 13.45 and 24.4 ± 16.54 at 2 and 6 months in the newly developed PRGF group (within subjects P = .001), and from 38.8 ± 12.62 to 27.8 ± 11.01 and 27.4 ± 11.38 at 2 and 6 months in the HA group (within subjects P = .001), respectively (between subjects P = .631). There was no significant difference between PRGF and HA groups in patients’ satisfaction and minor complications of injection, whereas patients in HA group reported significantly lower injection-induced pain. Conclusions: In 6 months follow up, our newly developed PRGF and HA, both are effective options to decrease pain and improvement of function in patients with symptomatic mild to moderate knee osteoarthritis.

In particular, total WOMAC index decreased from 42.9 ± 13.51 to 26.8 ± 13.45 and 24.4 ± 16.54 at 2 and 6 months in the newly developed PRGF group (within subjects P  = .001, and from 38.8 ± 12.62 to 27.8 ± 11.01 and 27.4 ± 11.38 at 2 and 6 months in the HA group (within subjects P  = .001, respectively (between subjects P  = .631. There was no significant difference between PRGF and HA groups in patients’ satisfaction and minor complications of injection, whereas patients in HA group reported significantly lower injection-induced pain. Conclusions: In 6 months follow up, our newly developed PRGF and HA, both are effective options to decrease pain and improvement of function in patients with symptomatic mild to moderate knee osteoarthritis.

    Full Text Available Abstract Background Fractures of the distal radius represent the most common fracture in elderly patients, and often indicate the onset of symptomatic osteoporosis. A variety of treatment options is available, including closed reduction and plaster casting, K-wire-stabilization, external fixation and open reduction and internal fixation (ORIF with volar locked plating. The latter is widely promoted by clinicians and hardware manufacturers. Closed reduction and cast stabilization for six weeks is a simple, convenient, and ubiquitously available intervention. In contrast, ORIF requires hospitalization, but allows for functional rehabilitation.

    Intra-articular injection of platelet-rich plasma (PRP) has been established as a suitable treatment for knee osteoarthritis. Here, we present a double-blind randomized controlled clinical trial, conducted in a public Hospital of the Spanish National Health Care System, to evaluate the efficacy of injecting autologous PRP versus hyaluronic acid (HA) in knee osteoarthritis. PRP was manufactured in Malaga's Regional Blood Center (Spain). Patients that met the eligibility criteria were randomized into a PRP group or a HA group. Pain and functional improvements were assessed pre- and post-treatment (three and six months follow-up) using the Visual Analogue Scale (VAS); the Knee and Osteoarthritis Outcome System (KOOS) scale and the European Quality of Life scale (EUROQOL). Both groups presented pain reduction at six months. The VAS scores for the PRP group improved by at least 50% from their initial value, particularly at three months following the final infiltration, with results resembling those of the HA group at six months. PRP was more effective in patients with lower osteoarthritis grades. Both treatments improved pain in knee osteoarthritis patients without statistically significant differences between them. However, PRP injection was proved to improve pain three months after the final infiltration and to be more effective in lower osteoarthritis grades.

    To assess the clinical efficacy and safety of a treatment based on one cycle versus two cycles of intra-articular injections of plasma rich in growth factors (PRGF-Endoret) on patients with knee osteoarthritis (OA). Ninety patients with knee OA were included and evaluated. A total of 48 patients received one cycle (OC group) (3 injections on a weekly basis), while 42 patients received two cycles of PRGF-Endoret (TC group) spaced 6 months between them. Patients were evaluated with LEQUESNE and WOMAC scores before treatment and after 48 weeks. Safety assessment was also performed. A significant reduction of all assessed outcome measures was shown for both groups at 48 weeks compared with baseline values (P PRGF did not show a significantly higher pain reduction compared with one cycle treatment. However, two cycles of PRGF showed a significant improvement in WOMAC stiffness, LEQUESNE MCD, LEQUESNE ADV and LEQUESNE global subscales. Therefore, patients treated with two cycles present an improvement in quality of life. II.

    Background and purpose: We sought to evaluate the nature and frequency of late toxicities in a cohort of nasopharyngeal cancer (NPC) patients treated with conventional radiotherapy alone. Methods and materials: Seven-hundred and ninety-six consecutive NPC patients treated using conventional radiotherapy at a single center from 1992 to 1995 were retrospectively analyzed. Patients with histology proven, completely staged, Stage I-IVB World Health Organization Type I-III NPC and completed radical radiotherapy were included. Patients with incomplete staging investigations, distant metastases at diagnosis, previous treatment, and incomplete radiotherapy were excluded. Radiotherapy-related complications were categorized using the RTOG Late Radiation Morbidity Scoring Criteria. Results: Median follow-up was 7.2 years. The 5-year overall survival and disease free survival were 69% and 56%, respectively, and the corresponding 10-year rates were 52% and 44%. Among 771 patients with at least 3 months of follow-up post treatment, 565 (73%) developed RT-related complications. Diagnosed neurological complications were cranial nerve palsies (n = 70; 9%), temporal lobe necrosis (n = 37; 5%), Lhermitte's syndrome (n = 7; 1%), and brachial plexopathy (n = 2; 0.3%). Non-neurological complications included xerostomia (n = 353; 46%), neck fibrosis (n = 169; 22%), hypo-pituitarism (n = 48; 6%), hearing loss (n = 120; 16%), dysphagia (n = 116; 15%), otorrhea (n = 101; 13%), tinnitus (n = 94; 12%), permanent tube feeding (n = 61; 8%), trismus (n = 45; 6%), second malignancies within treatment field (n = 17; 2%), and osteo-radionecrosis (n = 13; 2%). Conclusions: While radiotherapy is curative in NPC, many patients suffer significant late treatment morbidities with conventional radiotherapy techniques.

    Joint injury dramatically enhances the onset of osteoarthritis (OA) and is responsible for an estimated 12% of OA. Post-traumatic arthritis (PTA) is especially common after intraarticular fracture, and no disease-modifying therapies are currently available. We hypothesized that the delivery of mesenchymal stem cells (MSCs) would prevent PTA by altering the balance of inflammation and regeneration after fracture of the mouse knee. Additionally, we examined the hypothesis that MSCs from the MRL...

    The therapeutic approach to soft tissue sarcomas (STS) has evolved over the past two decades based on the results from randomized controlled trials, which are guiding physicians in the treatment decision-making process. Despite significant improvements in the control of local disease, a significant number of patients ultimately die of recurrent/metastatic disease following radical surgery due to a lack of effective adjuvant treatments. In addition, the characteristic chemoresistance of STS has compromised the therapeutic value of conventional antineoplastic agents in cases of unresectable advanced/metastatic disease. Therefore, novel therapeutic strategies are urgently needed to improve the prognosis of patients with STS. Recent advances in STS biology are paving the way to the development of molecularly targeted therapeutic strategies, the efficacy of which relies not only on the knowledge of the molecular mechanisms underlying cancer development/progression but also on the personalization of the therapeutic regimen according to the molecular features of individual tumours. In this work, we review the state-of-the-art of conventional treatments for STS and summarize the most promising findings in the development of molecularly targeted therapeutic approaches.

Patients diagnosed with AGA may experience decreased quality of life, depression, and feel self-conscious. There are a variety of therapeutic options ranging from prescription drugs to non-prescription medications. Currently, AGA involves an annual global market revenue of US$4 billion and a growth rate of 1.8%, indicating a growing consumer market. Although natural and synthetic ingredients can promote hair growth and, therefore, be useful to treat AGA, some of them have important adverse effects and unknown mechanisms of action that limit their use and benefits. Biologic factors that include signaling from stem cells, dermal papilla cells, and platelet-rich plasma are some of the current therapeutic agents being studied for hair restoration with milder side effects. However, most of the mechanisms exerted by these factors in hair restoration are still being researched. In this review, we analyze the therapeutic agents that have been used for AGA and emphasize the potential of new therapies based on advances in stem cell technologies and regenerative medicine.

    Magnetic resonance (MR) imaging has been definitively established as the reference standard in the evaluation of joints in the body. Similarly, magnetic resonance arthrography has emerged as a technique that has been proven to increase significantly the diagnostic performance if compared with conventional MR imaging, especially when dealing with fibrocartilage and articular cartilage abnormalities. Diluted gadolinium can be injected in the joint space using different approaches: under palpation using anatomic landmarks or using an imaging guidance, such as fluoroscopy, computed tomography, or ultrasound. Fluoroscopy has been traditionally used, but the involvement of ionizing radiation should represent a remarkable limitation of this modality. Conversely, ultrasound has emerged as a feasible, cheap, quick, and radiation-free modality that can be used to inject joints, with comparable accuracy of fluoroscopy. In the present paper, we discuss the advantages and disadvantages of using fluoroscopy or ultrasound in injecting gadolinium-based contrast agents in joints to perform magnetic resonance arthrography, also in view of the new EuroSAFE Imaging initiative promoted by the European Society of Radiology and the recent updates to the European Atomic Energy Community 2013/59 directive on the medical use of ionizing radiation.

    Intra-articular (IA) corticosteroids relieve osteoarthritis (OA) pain, but rapid absorption into systemic circulation may limit efficacy and produce untoward effects. We compared the pharmacokinetics (PK) of IA triamcinolone acetonide (TA) delivered as an extended-release, microsphere-based formulation (FX006) vs a crystalline suspension (TAcs) in knee OA patients. This Phase 2 open-label study sequentially enrolled 81 patients who received a single IA injection of FX006 (5 mL, 32 mg delivered dose, N = 63) or TAcs (1 mL, 40 mg, N = 18). Synovial fluid (SF) aspiration was attempted in each patient at baseline and one post-IA-injection visit (FX006: Week 1, Week 6, Week 12, Week 16 or Week 20; TAcs: Week 6). Blood was collected at baseline and multiple post-injection times. TA concentrations (validated LC-MS/MS, geometric means (GMs)), PK (non-compartmental analysis models), and adverse events (AEs) were assessed. SF TA concentrations following FX006 were quantifiable through Week 12 (pg/mL: 231,328.9 at Week 1; 3590.0 at Week 6; 290.6 at Week 12); post-TAcs, only two of eight patients had quantifiable SF TA at Week 6 (7.7 pg/mL). Following FX006, plasma TA gradually increased to peak (836.4 pg/mL) over 24 h and slowly declined to IA injection prolonged SF joint residency, diminished peak plasma levels, and thus reduced systemic TA exposure relative to TAcs.

    Purpose: To compare whole-brain radiation therapy (WBRT) with WBRT combined with thalidomide for patients with brain metastases not amenable to resection or radiosurgery. Patients and Methods: Patients with Zubrod performance status 0-1, MRI-documented multiple (>3), large (>4 cm), or midbrain brain metastases arising from a histopathologically confirmed extracranial primary tumor, and an anticipated survival of >8 weeks were randomized to receive WBRT to a dose of 37.5 Gy in 15 fractions with or without thalidomide during and after WBRT. Prerandomization stratification used Radiation Therapy Oncology Group (RTOG) Recursive Partitioning Analysis (RPA) Class and whether post-WBRT chemotherapy was planned. Endpoints included overall survival, progression-free survival, time to neurocognitive progression, the cause of death, toxicities, and quality of life. A protocol-planned interim analysis documented that the trial had an extremely low probability of ever showing a significant difference favoring the thalidomide arm given the results at the time of the analysis, and it was therefore closed on the basis of predefined statistical guidelines. Results: Enrolled in the study were 332 patients. Of 183 accrued patients, 93 were randomized to receive WBRT alone and 90 to WBRT and thalidomide. Median survival was 3.9 months for both arms. No novel toxicities were seen, but thalidomide was not well tolerated in this population. Forty-eight percent of patients discontinued thalidomide because of side effects. Conclusion: Thalidomide provided no survival benefit for patients with multiple, large, or midbrain metastases when combined with WBRT; nearly half the patients discontinued thalidomide due to side effects

    A best evidence topic in cardiac surgery was written according to a structured protocol. The question addressed was whether vacuum-assisted closure therapy (VAC) is superior to conventional therapy for treating post-sternotomy mediastinitis. Altogether >261 papers were found using the reported search, of which 9 represented the best evidence to answer the clinical question. The authors, journal, date and country of publication, patient group studied, study type, relevant outcomes and results of these papers are tabulated. Several studies indicate that VAC therapy is associated with shorter lengths of intensive care and in-hospital stay as well as faster rates of wound healing and fewer dressing changes. It has also been shown that VAC therapy is correlated with a statistically significant reduction in reinfection rates, particularly those that occur in the early postoperative period (at the 1-week follow-up). Patients can be discharged with the dressing in situ and managed in the community with a view to delayed closure or reconstruction. However, the studies comparing VAC with conventional therapy are all retrospective in nature and reinforce the need for randomized controlled trials in order to more accurately establish differences in outcomes between VAC and conventional therapy. Additionally, owing tło the variability of treatment protocols within the non-VAC arm, it is more challenging to draw definitive conclusions regarding the superiority of VAC therapy to every modality that is considered conventional treatment. We conclude that VAC therapy is a portable and an increasingly economical option for the treatment of post sternotomy mediastinitis. Although reductions in mortality rates were not reproduced in all studies, evidence suggests that VAC should still be considered as a first-line therapy for post-sternotomy mediastinitis and as a bridge therapy to musculocutaneous reconstruction or primary closure.

    Full Text Available INTRODUCTION Breast cancer is the most common cancer in women worldwide and a leading cause of cancer death in females and accounts for 1.8 million new cases and approximately 0.5 million deaths annually. Patients who present with locally advanced breast cancer (LABC require multidisciplinary team approach that incorporates diagnostic imaging, surgery, chemotherapy and histopathological assessment, including molecular-based studies, radiation, and, if indicated, biologic and hormonal therapies. Hypofractionated radiation therapy following mastectomy has been used in many institutions for several decades and have demonstrated equivalent local control, cosmetic and normal tissues between 50 Gy in 25 fractions and various hypofractionated radiotherapy prescriptions employing 13-16 fractions. Evidence suggests that hypofractionated radiotherapy may also be safe and effective for regional nodal disease. AIMS AND OBJECTIVES To compare the local control and side effects of hypofractionated radiation therapy with conventional radiation therapy in post mastectomy carcinoma breast with stage II and III and to compare the tolerability and compliance of both schedules. MATERIALS AND METHODS The study was conducted on 60 histopathologically proven patients of carcinoma of breast, treated surgically with modified radical mastectomy. Group I patients were given external radiation to chest flap and drainage areas, a dose of 39 Gy/13 fractions/3.1 weeks, a daily dose 3 Gy for 13 fractions in 4 days a week schedule and Group II patients were given external radiation to chest flap and drainage areas, a dose of 50 Gy/25 fractions/5 weeks, to receive a daily dose 2 Gy for 25 fractions in a 5 days a week schedule. RESULTS The median age at presentation in Group I and II was 48 and 50 years respectively. Locoregional control after completion of radiotherapy in Group I vs. Group II was 26/30 (86.7% vs. 27/30 (90% respectively. Acute reactions and their grades in Group

    The aim of this study is to determine the clinical efficacy of high-flow nasal cannula (HFNC) therapy compared with conventional oxygen therapy in children presented with respiratory distress. This was a randomized controlled study. Infants and children aged between 1 month to 5 years who were admitted to our tertiary referral center for respiratory distress (July 1, 2014 to March 31, 2015) and met the inclusion criteria were recruited. Infants and children hospitalized with respiratory distress were randomized into two groups of interventions. All clinical data, for example, respiratory score, pulse rate, and respiratory rate were recorded. The results were subsequently analyzed. A total of 98 respiratory distress children were enrolled during the study period. Only 4 children (8.2%) failed in HFNC therapy, compared with 10 children (20.4%) in conventional oxygen therapy group ( P = 0.09). After adjusted for body weight, underlying diseases, and respiratory distress score, there was an 85% reduction in the odds of treatment failure in HFNC therapy group (adjusted odds ratio 0.15, 95% confidence interval 0.03-0.66, P = 0.01). Most children in HFNC therapy group had significant improvement in clinical respiratory score, heart rate, and respiratory rate at 240, 360, and 120 min compared with conventional oxygen therapy ( P = 0.03, 0.04, and 0.03). HFNC therapy revealed a potential clinical advantage in management children hospitalized with respiratory distress compared with conventional respiratory therapy. The early use of HFNC in children with moderate-to-severe respiratory distress may prevent endotracheal tube intubation. TCTR 20170222007.

    While conventional chemotherapy is effective at eliminating the bulk of leukemic cells, chemotherapy resistance in acute myeloid leukemia (AML) is a prevalent problem that hinders conventional therapies and contributes to disease relapse, and ultimately patient death. We have recently shown that allogeneic double negative T cells (DNTs) are able to target the majority of primary AML blasts in vitro and in patient-derived xenograft models. However, some primary AML blast samples are resistant to DNT cell therapy. Given the differences in the modes of action of DNTs and chemotherapy, we hypothesize that DNT therapy can be used in combination with conventional chemotherapy to further improve their anti-leukemic effects and to target chemotherapy-resistant disease. Drug titration assays and flow-based cytotoxicity assays using ex vivo expanded allogeneic DNTs were performed on multiple AML cell lines to identify therapy-resistance. Primary AML samples were also tested to validate our in vitro findings. Further, a xenograft model was employed to demonstrate the feasibility of combining conventional chemotherapy and adoptive DNT therapy to target therapy-resistant AML. Lastly, blocking assays with neutralizing antibodies were employed to determine the mechanism by which chemotherapy increases the susceptibility of AML to DNT-mediated cytotoxicity. Here, we demonstrate that KG1a, a stem-like AML cell line that is resistant to DNTs and chemotherapy, and chemotherapy-resistant primary AML samples both became more susceptible to DNT-mediated cytotoxicity in vitro following pre-treatment with daunorubicin. Moreover, chemotherapy treatment followed by adoptive DNT cell therapy significantly decreased bone marrow engraftment of KG1a in a xenograft model. Mechanistically, daunorubicin increased the expression of NKG2D and DNAM-1 ligands on KG1a; blocking of these pathways attenuated DNT-mediated cytotoxicity. Our results demonstrate the feasibility and benefit of using DNTs as

    Previous reports have questioned whether an orthogonal or parallel configuration is superior for distal humeral articular fractures. In previous clinical and biomechanical studies, implant failure of the posterolateral plate has been reported with orthogonal configurations; however, the reason for screw loosening in the posterolateral plate is unclear. The purpose of this study was to evaluate biomechanical properties and to clarify the causes of posterolateral plate loosening using a humeral fracture model under axial compression on the radial or ulnar column separately. And we changed only the plate set up: parallel or orthogonal. We used artificial bone to create an Association for the Study of Internal Fixation type 13-C2.3 intra-articular fracture model with a 1-cm supracondylar gap. We used an anatomically-preshaped distal humerus locking compression plate system (Synthes GmbH, Solothurn, Switzerland). Although this is originally an orthogonal plate system, we designed a mediolateral parallel configuration to use the contralateral medial plate instead of the posterolateral plate in the system. We calculated the stiffness of the radial and ulnar columns and anterior movement of the condylar fragment in the lateral view. The parallel configuration was superior to the orthogonal configuration regarding the stiffness of the radial column axial compression. There were significant differences between the two configurations regarding anterior movement of the capitellum during axial loading of the radial column. The posterolateral plate tended to bend anteriorly under axial compression compared with the medial or lateral plate. We believe that in the orthogonal configuration axial compression induced more anterior displacement of the capitellum than the trochlea, which eventually induced secondary fragment or screw dislocation on the posterolateral plate, or nonunion at the supracondylar level. In the parallel configuration, anterior movement of the capitellum or

Methods The data of 40 consecutive patients, 29 women and 11 men, who were prospectively followed up for 6 months, using a standardized procedure, were retrospectively analyzed. All patients have received a single intra-articular injection of H Anox-M-XL (4.4 mL, viscosupplement made of a cross-linked HA (16 mg/mL + mannitol (35 mg/mL, in the target knee. The primary outcome was safety. The secondary end points included 3- and 6-month change in the WOMAC pain (0–50 and WOMAC total (0–240 and patient's global assessment (PGA. Patient's self-assessment of treatment efficacy (0–3 and analgesic consumption were obtained at months 3 and 6. An intent-to-treat analysis was performed. Results Mean (SD age was 60.7 (13.9 years, and mean BMI was 28.6 (5.0. Kellgren–Lawrence radiological grade was I/II and III/IV in 13 and 27 of the subjects, respectively. The average WOMAC pain and WOMAC total scores at baseline were 21.5 (9.8 and 89.9 (42.8, respectively. Thirty-nine patients completed the follow-up. HAnox-M-XL was well tolerated; two patients experienced knee pain after injection, which resolved within three days. No treatment-related severe adverse event was reported. Mean (SD variations in WOMAC pain and WOMAC total scores were –8.2 (8.9 and –38.4 (35.6, respectively, at month 6 ( P = 0.001. PGA decreased from 5.5 (2.0 to 3.0 (2.2 ( P = 0.006. Efficacy was rated as good or very good in 76.9% of the cases. Most of the regular analgesics users decreased their consumption. Conclusion Treatment with one injection of 4.4 mL HAnox-M-XL is effective to alleviate KOA symptoms over six months, without safety concern. Controlled trials are needed to confirm these pilot data.

    The aim of this study is to assess the effectiveness of Radiosynovectomy (RSV) using (177)Lu-labeled hydroxyapatite ((177)Lu-HA) in the treatment of painful synovitis and recurrent joint effusion of knee joints in rheumatoid arthritis (RA). Ten patients, diagnosed with RA and suffering from chronic painful resistant synovitis of the knee joints were referred for RSV. The joints were treated with 333 ± 46 MBq of (177)Lu-HA particles administered intra-articularly. Monitoring of activity distribution was performed by static imaging of knee joint and whole-body gamma imaging. The patients were evaluated clinically before RSV and at 6 months after the treatment by considering the pain improvement from baseline values in terms of a 100-point visual analog scale (VAS), the improvement of knee flexibility and the pain remission during the night. RSV response was classified as poor (VAS body scan. Static scans of the joint at 1 month revealed complete retention of (177)Lu-HA in the joints. All patients showed decreased joint swelling and pains, resulting in increased joint motion after 6 months. The percentage of VAS improvement from baseline values was 79.5 ± 20.0% 6 months after RS and found to be significantly related to patients' age (P = 0.01) and duration of the disease (P = 0.03). Knees with Steinbrocker's Grades 0 and I responded better than those with more advanced changes (Steinbrocker's Grades III and IV) in terms of VAS improvement (75% vs. 45.8%) (P level was not different before and after RSV. RSV side-effects assessed for the whole follow-up period were minor and not significant. RSV with (177)Lu-HA was safe and effective in patients with knee joint chronic painful synovitis of rheumatoid origin. It exhibited significant therapeutic effect after 6 months follow-up period with no significant side-effects. The preliminary investigations reveal that (177)Lu-labeled HA particles hold considerable promise as a cost-effective agent for RSV. More elaborate and

    The purpose of this study was to compare the efficacy and safety in a randomized, clinical trial of 3 injections of PRGF-Endoret (BTI Biotechnology Institute, Vitoria, Spain) versus one single intra-articular injection of Durolane hyaluronic acid (HA) (Q-MED AB, Uppsala, Sweden) as a treatment for reducing symptoms in patients with knee osteoarthritis (OA). Ninety-six patients with symptomatic knee OA were randomly assigned to receive PRGF-Endoret (3 injections on a weekly basis) or one infiltration with Durolane HA. The primary outcome measures were a 30% decrease and a 50% decrease in the summed score for the pain, physical function, and stiffness subscales of the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC) and Lequesne scores from baseline to weeks 24 and 48. The percentage of OMERACT-OARSI (Outcome Measures for Rheumatology Committee and Osteoarthritis Research Society International Standing Committee for Clinical Trials Response Criteria Initiative) responders was also documented. As secondary outcomes, pain, stiffness, and physical function by use of the WOMAC and the Lequesne score were considered and overall safety of the injection themselves. The mean age of the patients was 63.6 years. Treatment with PRGF-Endoret was significantly more efficient than treatment with Durolane HA in reducing knee pain and stiffness and improving physical function in patients with knee OA. The rate of response to PRGF-Endoret was significantly higher than the rate of response to HA for all the scores including pain, stiffness, and physical function on the WOMAC, Lequesne index, and OMERACT-OARSI responders at 24 and 48 weeks. Adverse events were mild and evenly distributed between the groups. Our findings show that PRGF-Endoret is safe and significantly superior to Durolane HA in primary and secondary efficacy analysis both at 24 and 48 weeks; provides a significant clinical improvement, reducing patients' pain and improving joint stiffness and

    Gastroparesis is a debilitating condition that causes nausea, vomiting, and abdominal pain. Management includes analgesics and antiemetics, but symptoms are often refractory. Haloperidol has been utilized in the palliative care setting for similar symptoms. The study objective was to determine whether haloperidol as an adjunct to conventional therapy would improve symptoms in gastroparesis patients presenting to the emergency department (ED). This was a randomized, double-blind, placebo-controlled trial of adult ED patients with acute exacerbation of previously diagnosed gastroparesis. The treatment group received 5 mg of haloperidol plus conventional therapy (determined by the treating physician). The control group received a placebo plus conventional therapy. The severity of each subject's abdominal pain and nausea were assessed before intervention and every 15 minutes thereafter for 1 hour using a 10-point scale for pain and a 5-point scale for nausea. Primary outcomes were decreased pain and nausea 1 hour after treatment. Of the 33 study patients, 15 were randomized to receive haloperidol. Before treatment, the mean intensity of pain was 8.5 in the haloperidol group and 8.28 in the placebo group; mean pretreatment nausea scores were 4.53 and 4.11, respectively. One hour after therapy, the mean pain and nausea scores in the haloperidol group were 3.13 and 1.83 compared to 7.17 and 3.39 in the placebo group. The reduction in mean pain intensity therapy was 5.37 in the haloperidol group (p ≤ 0.001) compared to 1.11 in the placebo group (p = 0.11). The reduction in mean nausea score was 2.70 in the haloperidol group (p ≤ 0.001) and 0.72 in the placebo group (p = 0.05). Therefore, the reductions in symptom scores were statistically significant in the haloperidol group but not in the placebo group. No adverse events were reported. Haloperidol as an adjunctive therapy is superior to placebo for acute gastroparesis symptoms. © 2017 by the Society for Academic

    The informational value of conventional tomography as primary diagnostic method is pointed out in diseases of nasal sinuses resistant to therapy. 5 cases demonstrate the additional information gained by CT-differentiation of soft tissue structures, intraorbital and intracranial expansion. In 78.4% of the examined group of 51 patients conventional tomography allowed the diagnosis of a process limited to the nasal sinuses, further evidence by CT could be omitted. In 11 patients examined by CT additionally, the expansion of the process was defined more precisely and the assumed intraorbital and intracranial growth confirmed. (orig.) [de

    Individuals with chronic stroke often have long-lasting upper extremity impairments that impede function during activities of daily living. Rehabilitation robotics have shown promise in improving arm function, but current systems do not allow realistic training of activities of daily living. We have incorporated the ARMin III and HandSOME device into a novel robotic therapy modality that provides functional training of reach and grasp tasks. To compare the effects of equal doses of robotic and conventional therapy in individuals with chronic stroke. Subjects were randomized to 12 hours of robotic or conventional therapy and then crossed over to the other therapy type after a 1-month washout period. Twelve moderate to severely impaired individuals with chronic stroke were enrolled, and 10 completed the study. Across the 3-month study period, subjects showed significant improvements in the Fugl-Meyer (P = .013) and Box and Blocks tests (P = .028). The robotic intervention produced significantly greater improvements in the Action Research Arm Test than conventional therapy (P = .033). Gains in the Box and Blocks test from conventional therapy were larger than from robotic therapy in subjects who received conventional therapy after robotic therapy (P = .044). Data suggest that robotic therapy can elicit improvements in arm function that are distinct from conventional therapy and supplements conventional methods to improve outcomes. Results from this pilot study should be confirmed in a larger study.

Methods: A decision-analytic model in Microsoft Excel was used to compare vedolizumab with conventional therapy (aminosalicylates, corticosteroids, immunomodulators for the treatment of patients with UC in the UK. We considered the following three populations: the overall intent-to-treat population from the GEMINI I trial, patients naïve to anti-TNF therapy, and those who had failed anti-TNF-therapy. Population characteristics and efficacy data were obtained from the GEMINI I trial. Other inputs (eg, unit costs, probability of surgery, mortality were obtained from published literature. Time horizon was a lifetime horizon, with costs and outcomes discounted by 3.5% per year. One-way and probabilistic sensitivity analyses were conducted to measure the impact of parameter uncertainty. Results: Vedolizumab had incremental cost-effectiveness ratios of £4,095/quality-adjusted life-year (QALY, £4,423/QALY, and £5,972/QALY compared with conventional therapy in the intent-to-treat, anti-TNF-naïve, and anti-TNF-failure populations, respectively. Patients on vedolizumab accrued more QALYs while incurring more costs than patients on conventional therapy. The sensitivity analyses showed that the results were most sensitive to induction response and transition probabilities for each treatment. Conclusion: The results suggest that vedolizumab results in more QALYs and may be a cost-effective treatment option compared with conventional therapy for both anti

    To know the survival rate in patients with RIFLE I and II stages on acute renal failure, treated with supportive care or continuous renal replacement therapy with PRISMA machine, at an intensive care unit. There were included patients of both sexes, aged 16 to 69 years, with acute renal failure in RIFLE I and II stages and score of scale APACHE II lower than 36 points. The sample studied was divided in two groups: a group was treated with supportive care, and the other group received continuous renal replacement therapy via PRISMA machine. We compared mortality between both groups and the association with the RIFLE stages with Pearson's chi-squared test. The average score of the scale APACHE I was 14 points, and the probability of death was 15 %. The patients with acute renal failure RIFLE I were 54.5 % and RIFLE II 45.5 %, with mortality of 30.4 % and 38.8 %, respectively. Patients in RIFLE I stage who received supportive care and continuous replacement therapy had non-statistical differences in mortality (p = 0.356). The mortality in patients with acute renal failure in RIFLE II stage treated with continuous replacement therapy was higher (p = 0.000). Because of its accessibility and lower mortality, supportive care should be the initial procedure in patients with acute renal failure in RIFLE I and II stages.

    To compare the effectiveness of Homeopathy and Conventional therapy in Acute Otitis Media (AOM). A randomized placebo-controlled parallel group pilot study of homeopathic vs conventional treatment for AOM was conducted in Jaipur, India. Patients were randomized by a computer generated random number list to receive either individualized homeopathic medicines in fifty millesimal (LM) potencies, or conventional treatment including analgesics, antipyretics and anti-inflammatory drugs. Patients who did not improve were prescribed antibiotics at the 3rd day. Outcomes were assessed by the Acute Otitis Media-Severity of Symptoms (AOM-SOS) Scale and Tympanic Membrane Examination over 21 days. 81 patients were included, 80 completed follow-up: 41 for conventional and 40 for homeopathic treatment. In the Conventional group, all 40 (100%) patients were cured, in the Homeopathy group, 38 (95%) patients were cured while 02 (5%) patients were lost to the last two follow-up. By the 3rd day of treatment, 4 patients were cured in Homeopathy group but in Conventional group only one patient was cured. In the Conventional group antibiotics were prescribed in 39 (97.5%), no antibiotics were required in the Homeopathy group. 85% of patients were prescribed six homeopathic medicines. Individualized homeopathy is an effective conventional treatment in AOM, there were no significant differences between groups in the main outcome. Symptomatic improvement was quicker in the Homeopathy group, and there was a large difference in antibiotic requirements, favouring homeopathy. Further work on a larger scale should be conducted.

    Full Text Available Introduction: The efficacy of conventional therapy viz. finasteride and minoxidil in androgenetic alopecia (AGA that is based on both preventing hair loss and promoting new hair growth, varies between 30% and 60%. This has led to a large number of patients unsatisfied who demand for a better cosmetic coverage over the scalp. Microneedling has recently been reported to be promising, effective and a safe treatment modality in the treatment of AGA. This augments the response of conventional therapy. Materials and Methods: Four men with AGA were on finasteride and 5% minoxidil solution since 2 to 5 years. Though there was no worsening in their respective AGA stages with the therapy, they showed no new hair growth. They were subjected to microneedling procedure over a period of 6 months along with their ongoing therapy. Patients were assessed with the use of the standardized 7-point evaluation scale and patients′ subjective hair growth assessment scale. The patients were followed up for 18 months post microneedling procedure to assess the sustainability of the response. Results: All patients showed a response of + 2 to + 3 on standardized 7-point evaluation scale. The response in the form of new hair growth started after 8-10 sessions. The patients′ satisfaction was more than 75% in three patients and more 50% in one patient, on patients′ subjective hair growth assessment scale. The obtained results were sustained post procedure during 18 months follow-up period. Conclusion : Treatment with microneedling showed an accelerated response with addition of microneedling procedure leading to significant scalp density. This is the first case series to report the boosting effect of microneedling with respect to new hair follicle stimulation in patients with androgenetic alopecia who were poor responders to conventional therapy.

    Purpose: To determine the incidence of and risk factors for radiation pneumonitis (RP) after stereotactic ablative radiation therapy (SABR) to the lung in patients who had previously undergone conventional thoracic radiation therapy. Methods and Materials: Seventy-two patients who had previously received conventionally fractionated radiation therapy to the thorax were treated with SABR (50 Gy in 4 fractions) for recurrent disease or secondary parenchymal lung cancer (T 10 and mean lung dose (MLD) of the previous plan and the V 10 -V 40 and MLD of the composite plan were also related to RP. Multivariate analysis revealed that ECOG PS scores of 2-3 before SABR (P=.009), FEV1 ≤65% before SABR (P=.012), V 20 ≥30% of the composite plan (P=.021), and an initial PTV in the bilateral mediastinum (P=.025) were all associated with RP. Conclusions: We found that severe RP was relatively common, occurring in 20.8% of patients, and could be predicted by an ECOG PS score of 2-3, an FEV1 ≤65%, a previous PTV spanning the bilateral mediastinum, and V 20 ≥30% on composite (previous RT+SABR) plans. Prospective studies are needed to validate these predictors and the scoring system on which they are based.

    Progressive peri-implanter bone losses, which are accompanied by inflammatory process in the soft tissues is referred to as peri-implantitis. The aim of this study was to compare the effects of lethal photosensitisation with the conventional technique on bacterial reduction in ligature induced peri-implantitis in dogs. Seventeen third pre-molars of Labrador dogs were extracted and, immediately after, the implants were submerged. After osteointegration, peri-implantitis was induced. After 4 months, ligature were removed and the same period was waited for natural induction of bacterial plaque. The dogs were randomly divided into two groups. In the conventional group, they were treated with the conventional techniques of mucoperiosteal flaps for scaling the implant surface and irrigate it. In the laser group, only mucoperiosteal scaling was carried out before photodynamic therapy. On the peri-implanter pocket an azulene paste was injected and a GaAlAs low-power laser (λ= 660 nm, P= 30 mW, E= 5,4 J and Δt= 3 min.). Microbiological samples were obtained before and immediately after treatment. One implant was removed to be analyzed by scan electron microscopy to verify contamination on the implant surface. The results of this study showed that Prevotella sp., Fusobacterium e S. Beta-haemolyticus were significantly reduced for the conventional and laser groups. (author)

    Objective: To compare the spine intensity modulated radiation therapy (IMRT) and the conventional radiation therapy on the beagle spinal cord neurons, in order to prove the biological safety of IMRT of the spinal cord. Methods: Twelve selected purebred beagles were randomly divided into 2 groups. A beagle clinical model of tumor was mimiced in the ninth and tenth thoracic vertebrae. Then the beagles were irradiated by 2 different models of intensity modulated radiotherapy and conventional radiation therapy, with the total irradiation doses of 50 and 70 Gy. The samples of spinal cord were taken out from the same position of the nine and tenth thoracic vertebrae at the third month after radiation.All the samples were observed by the electron microscope, and the Fas and HSP70 expression in spinal cord neurons were evaluated by immunohistochemistry method. Terminal deoxynucleatidyl transferase mediated dUTP nick and labeling (TUNEL) technique was used to examine the apoptotic cells in the spinal cord. Results: The neurons in the spinal cord of IMRT group were mainly reversible injury, and those in the conventional radiation therapy were mainly apoptosis. Compared with the conventional radiation therapy group [50 Gy group, (7.3 ± 1.1)%; 70 Gy group, (11.3 ± 1.4)%], the apoptosis rate of the spinal cord neurons of the intensity modulated radiotherapy group [50 Gy group, (1.2 ± 0.7)%; 70 Gy group (2.5 ± 0.8)%] was much lower[(50 Gy group, t=0.022, P<0.05; 70 Gy group, t=0.017, P<0.05)]. The expression levels of Fas in the IMPT group (50 Gy group, 4.6 ± 0.8; 70 Gy group, 7.4 ± 1.1) were also much lowerthan those in the other group (50 Gy group, 15.1 ± 6.4; 70 Gy group, 19.3 ± 7.6. 50 Gy group, t=0.231, P<0.05; 70 Gy group, t=0.457, P<0.05), while the expression levels of HSP70 in the IMPT group (50 Gy group, 9.1 ± 0.8; 70 Gy group, 7.3 ± 1.4)were much higher than those in the conventional radiation therapy group (50 Gy group, 2.1 ± 0.9; 70 Gy group, 1.7 ± 0

    Osteoarthritis (OA) is the most common form of arthritis. Over the last 20 years, attempts have been made to regenerate articular cartilage to overcome the limitations of conventional treatments. As OA is generally associated with larger and diffuse involvement of articular surfaces and alteration of joint homeostasis, a tissue engineering approach for cartilage regeneration is more difficult than in simple chondral defects. Autologous and allogeneic mesenchymal stem cells (MSCs) have rapidly emerged as investigational products for cartilage regeneration. This review outlines points to consider in MSC-based approaches for OA treatment, including allogeneic MSCs, sources of MSCs, dosages, feasibility of multiple injections, indication according to severity of OA lesion and patient age, and issues regarding implantation versus injection. We introduce possible mechanisms of action of implanted or injected MSCs as well as the immunological aspects of MSC therapy and provide a summary of clinical trials of MSCs in the treatment of OA. Given current knowledge, it is too early to draw conclusions on the ultimate effectiveness of intra-articular application of MSCs in terms of regenerative effects. Further radiological and histological data will be needed, with a larger pool of patients, before this question can be answered.

    Purpose: To review the various radiation therapy quality assurance (RTQA) procedures used by the Global Clinical Trials RTQA Harmonization Group (GHG) steering committee members and present the harmonized RTQA naming conventions by amalgamating procedures with similar objectives. Methods and Materials: A survey of the GHG steering committee members' RTQA procedures, their goals, and naming conventions was conducted. The RTQA procedures were classified as baseline, preaccrual, and prospective/retrospective data capture and analysis. After all the procedures were accumulated and described, extensive discussions took place to come to harmonized RTQA procedures and names. Results: The RTQA procedures implemented within a trial by the GHG steering committee members vary in quantity, timing, name, and compliance criteria. The procedures of each member are based on perceived chances of noncompliance, so that the quality of radiation therapy planning and treatment does not negatively influence the trial measured outcomes. A comparison of these procedures demonstrated similarities among the goals of the various methods, but the naming given to each differed. After thorough discussions, the GHG steering committee members amalgamated the 27 RTQA procedures to 10 harmonized ones with corresponding names: facility questionnaire, beam output audit, benchmark case, dummy run, complex treatment dosimetry check, virtual phantom, individual case review, review of patients' treatment records, and protocol compliance and dosimetry site visit. Conclusions: Harmonized RTQA harmonized naming conventions, which can be used in all future clinical trials involving radiation therapy, have been established. Harmonized procedures will facilitate future intergroup trial collaboration and help to ensure comparable RTQA between international trials, which enables meta-analyses and reduces RTQA workload for intergroup studies.

    Full Text Available Background: Amongst various modalities of post operative rehabilitation in a total knee replacement (TKR surgery, this study focuses on evaluating the effect of additional yoga therapy on functional outcome of TKR patients. Materials and Methods: A comparative study was done to compare the effects of conventional physiotherapy and additional yoga asanas, on 56 patients undergoing total knee arthroplasty due to osteoarthritis. After obtaining written informed consent, the patients were alternately assigned to two groups: Conventional and experimental. Baseline WOMAC scores for pain and stiffness were taken on third post operative day. The subjects in conventional group received physiotherapy rehabilitation program of Sancheti Institute where the study was conducted, the experimental group received additional modified yoga asanas once daily by the therapist. After discharge from the hospital, patients were provided with written instructions and photographs of the asanas, two sets of WOMAC questionnaire with stamped and addressed envelopes and were instructed to perform yoga asanas 3 days/week. Subjects filled the questionnaire after 6 weeks and 3 months from the day of surgery and mailed back. The primary outcome measure was WOMAC questionnaire which consists of 24 questions, each corresponding to a visual analog scale, designed to measure patient′s perception of pain, stiffness and function. Results: The results suggest that there was a significant change (P<0.05 for all the groups for pain, stiffness and function subscales of WOMAC scale. The pain and stiffness was found to be less in experimental group receiving additional yoga therapy than in conventional group on 3 rd post operative day, 6 weeks and 3 months after the surgery. Conclusion: A combination of physiotherapy and yoga asana protocol works better than only physiotherapy protocol. Larger and blinded study is needed.

    Patients with severe ischemic cardiomyopathy (left ventricular ejection fraction assist device as destination therapy is reserved for patients who are too high risk for conventional surgery. We evaluated our outcomes with conventional surgery within this population and the comparative effectiveness of these 2 therapies. We identified patients who underwent conventional surgery or left ventricular assist device as destination therapy for severe ischemic cardiomyopathy (left ventricular ejection fraction assist device as destination therapy. We compared baseline patient characteristics and outcomes in terms of end-organ function and survival. A total of 88 patients were identified; 55 patients underwent conventional surgery (63%), and 33 patients (37%) received a left ventricular assist device as destination therapy. Patients who received left ventricular assist device as destination therapy had the increased prevalence of renal failure, inotrope dependency, and intra-aortic balloon support. Patients undergoing conventional surgery required longer ventilatory support, and patients receiving a left ventricular assist device required more reoperation for bleeding. Mortality rates were similar between the 2 groups at 30 days (7% in the conventional surgery group vs 3% in the left ventricular assist device as destination therapy group, P = .65) and at 1 year (22% in the conventional surgery group vs 15% in the left ventricular assist device as destination therapy group, P = .58). There was a trend toward improved survival in patients receiving a left ventricular assist device compared with the propensity-matched groups at 1 year (94% vs 71%, P = .171). The operative mortality and early survival after conventional surgery seem to be acceptable. For inoperable or prohibitive-risk patients, left ventricular assist device as destination therapy can be offered with similar outcomes.

    Rehabilitation following total knee arthroplasty (TKA) is a costly, cumbersome, and often painful process. Physical therapy contributes to the successful outcome of TKA but can be expensive. Alternative methods of obtaining good functional results that help minimize costs are desirable. Neuromuscular electrical stimulation (NMES) is a potential option. Neuromuscular electrical stimulation has been shown to increase quadriceps muscle strength and activation following TKA. Functional scores also improve following TKA when NMES is added to conventional therapy protocols vs therapy alone. The authors hypothesized that rehabilitation managed by a physical therapist would not result in a functional advantage for patients undergoing TKA when compared with NMES and an unsupervised at-home range of motion exercise program and that patient satisfaction would not differ between the 2 groups. Seventy patients were randomized into a postoperative protocol of conventional physical therapy with a licensed therapist, including range of motion exercises and strengthening exercises, or into a program of NMES and range of motion exercises performed at home without therapist supervision. Noninferiority of the NMES program was obtained 6 weeks postoperatively (Knee Society pain/function scores, Western Ontario and McMaster Universities Osteoarthritis Index, flexion). Noninferiority was shown 6 months postoperatively for all parameters. The results suggest that rehabilitation managed by a physical therapist results in no functional advantage or difference in patient satisfaction when compared with NMES and an unsupervised at-home range of motion program. Neuromuscular electrical stimulation and unsupervised at-home range of motion exercises may provide an option for reducing the cost of the postoperative TKA recovery process without compromising quadriceps strength or patient satisfaction.

    Purpose: Two-dimensional GRID therapy, traditionally planned and delivered using a dedicated GRID block or MLC modulation, has shown clinical efficacy in treating bulky tumors. However, the large dose to normal tissues outside target can be limiting. We hypothesize that modulation in the third dimension will improve dose sparing of normal tissues, maximize the bystander effect within the target, and ultimately improve the therapy effectiveness. This study aims to investigate the feasibility of a three-dimensional GRID technique using conventional LINACs to achieve a 3D lattice of high dose volumes within a target. Methods: Datasets of patient’s having large tumor sizes were used to investigate the planning and delivering of 3D GRID using a Varian TrueBeam linac. Original patient contours of PTV are exported from a TPS to DICOManTX where 3D GRID targets are generated in programmable configurations. A structure of avoidance (SOA), i.e., PTV minus GRID targets, is also generated to facilitate inverse planning to achieve the desired pattern. The artificial structures were sent back to the TPS where an IMRT or VMAT plan is designed to deliver a desired high dose to GRID targets while minimizing the dose to the SOA as much as possible. Results: The programmable GRID target generator enables us to modify the target geometry to maximize the peak-to-valley ratio. Preliminary results show that plans based on spherical GRID targets achieve a higher peak-to-valley dose ratio compared with cylindrical targets. High dose spillage outside the target was eliminated. IMRT planning requires the number of beams to be larger than 16, while for VMAT the number of arcs should be at least 4 in order to achieve dosimetric goals. Conclusion: Planning and delivering 3D GRID therapy using conventional LINACs was shown to be feasible. More research and development are required before this new modality can be implemented clinically.

    Actinic keratosis is a precursor lesion to the most common nonmelanoma skin cancer. Conventional photodynamic therapy (PDT) has been shown to be effective, but the procedure is time-consuming, can be very painful, and requires infrastructure. These shortcomings led to the emergence of daylight PDT. To obtain a global estimate of efficacy, we undertook a systematic literature review and performed a meta-analysis of the available evidence on the efficacy and safety of daylight PDT as compared to conventional PDT in the treatment of actinic keratosis and/or field cancerization. The conclusion is that the difference in efficacy is clinically negligible (global estimate of the mean response rate difference, -3.69%; 95% CI, -6.54% to -0.84%). The adverse effects of daylight PDT are mild and localized (79% of patients report no discomfort), and patients report less pain (P<.001). Daylight PDT gives good to excellent cosmetic results in more than 90% of patients, and patient satisfaction is greater (P<.001). Copyright © 2016 AEDV. Publicado por Elsevier España, S.L.U.

    2011-01-01

    Full Text Available Metastatic germ cell tumours (GCTs are usually cured with cisplatin based chemotherapy and standard treatment algorithms are established. However when this treatment fails and the disease relapses, standard treatment is much more uncertain. Both conventional dose therapy (CDT and high dose therapy (HDT are widely used, due to the lack of conclusive data supporting one specific approach. A recent retrospective analysis focusing on this population suggested a significant benefit for HDT. Retrospective analyses are prone to bias, and therefore while this data is provocative it is by no mean conclusive. For this reason the international community is supporting a prospective randomised trial in this area comparing CDT(TIP with sequential HDT (TICE. The planned open labelled randomised phase III study (TIGER is due to open in 2011 and will recruit 390 patients to detect a 13% difference in 2 year progression free survival (primary endpoint. It is hoped that this large study will conclusively resolve the uncertainty which currently exists.

    To assess the outcome of retinal vasculitis in patients with Behçet disease treated with infliximab compared to treatment with conventional therapy. Nonrandomized, retrospective comparative clinical study. Patients with Behçet disease with all four major criteria were included in this study. Patients had recurrent episodes of uveitis and retinal vasculitis. Thirty-three patients (Group 1) were treated with oral prednisone, cyclosporine, and azathioprine or methotrexate for a minimum period of three months. Ten patients (Group 2) who failed to respond to conventional therapy were given infliximab at a dose of 5 mg/kg in a single intravenous infusion on day 1 and every two weeks for a total of six doses. Patients were given the same treatment during each subsequent relapse. The main outcome measures were the number of relapses, visual outcome, and ocular complications. The mean follow-up period was 36 months in Group 1 and 30 months in Group 2. The mean number of relapses was significantly reduced and the duration of remission was longer in the infliximab therapy group compared to conventional therapy group (P < .0001). The visual acuity at 24 months follow-up was significantly better in patients treated with infliximab (Group 2) when compared to conventional therapy (Group 1) (P = .0059). Patients with Behçet disease had significant decrease in inflammation, improvement of visual acuity, and reduced ocular complications following infliximab when compared to conventional therapy. The number of relapses was less in the infliximab treatment group than the conventional therapy group.

    The aim of this study was to determine the efficacy of electrical stimulation when added to conventional physical therapy with regard to clinical and neurophysiologic changes in patients with Bell palsy. This was a randomized controlled trial. Sixty patients diagnosed with Bell palsy (39 right sided, 21 left sided) were included in the study. Patients were randomly divided into two therapy groups. Group 1 received physical therapy applying hot pack, facial expression exercises, and massage to the facial muscles, whereas group 2 received electrical stimulation treatment in addition to the physical therapy, 5 days per week for a period of 3 wks. Patients were evaluated clinically and electrophysiologically before treatment (at the fourth week of the palsy) and again 3 mos later. Outcome measures included the House-Brackmann scale and Facial Disability Index scores, as well as facial nerve latencies and amplitudes of compound muscle action potentials derived from the frontalis and orbicularis oris muscles. Twenty-nine men (48.3%) and 31 women (51.7%) with Bell palsy were included in the study. In group 1, 16 (57.1%) patients had no axonal degeneration and 12 (42.9%) had axonal degeneration, compared with 17 (53.1%) and 15 (46.9%) patients in group 2, respectively. The baseline House-Brackmann and Facial Disability Index scores were similar between the groups. At 3 mos after onset, the Facial Disability Index scores were improved similarly in both groups. The classification of patients according to House-Brackmann scale revealed greater improvement in group 2 than in group 1. The mean motor nerve latencies and compound muscle action potential amplitudes of both facial muscles were statistically shorter in group 2, whereas only the mean motor latency of the frontalis muscle decreased in group 1. The addition of 3 wks of daily electrical stimulation shortly after facial palsy onset (4 wks), improved functional facial movements and electrophysiologic outcome measures at

    Purpose: To assess the long-term outcome of conventional external beam radiation therapy in the management of clinically confined prostate cancer and to examine the proposition that radiation accelerates tumor growth in those who fail treatment. Methods and Materials: One thousand and forty-four men with T1-4NxM0 prostate cancer treated by conventional external beam radiation therapy at the Massachusetts General Hospital between 1977 and 1991 were analyzed. Median follow-up was 49 months. Failure was defined as: two sequential rises in serum prostate specific antigen (PSA) level; or a PSA > 1 ng/ml 2 or more years after radiation; or any clinical failure. Kaplan-Meier actuarial analyses were used to assess outcome. Results: At 10 years only 40% of the T1-2 group remained disease free. When subdivided by grade, the well-differentiated tumors (Gleason 1-2) exhibited a 53% actuarial 10-year disease-free survival, moderately differentiated (Gleason 3) 42%, and poorly differentiated (Gleason 4-5) 20%. The corresponding values for the T3-4 men were 33% for Gleason 1-2, 20% for Gleason 3, and 10% for Gleason 4-5. Overall the value for T3-4 tumors was 18% at 10 years. On relapse the median PSA doubling times for the T1-2 patients were predicted by histology: 18.8 months for Gleason 1-2 patients; 11.1 months for Gleason 3; and 9.6 months for Gleason 5. Significant differences were found between the Gleason 3 and the Gleason 4-5 groups (p = 0.04) and the Gleason 1-2 and the Gleason 4-5 groups (p = 0.03). A wide range of doubling times was seen within each grade group. When compared with recently reported data on selected T1-2 patients who were managed by expectant observation there was no advantage over the first decade (and certainly no disadvantage) in terms of metastasis-free survival or disease-specific survival for the irradiated Gleason 1-3 patients. However, a gain was seen for those with Gleason 4-5 tumors. Conclusion: Less than half of the T1-2NxM0 and less than one

    Although breast cancer is a highly treatable disease, some women reject conventional treatment opting for unproven "alternative therapy" that may contribute to poor health outcomes. This study sought to understand why some women make this decision and to identify messages that might lead to greater acceptance of evidence-based treatment. This study explored treatment decision making through in-depth interviews with 60 breast cancer patients identified by their treating oncologists. Thirty refused some or all conventional treatment, opting for alternative therapies, whereas 30 accepted both conventional and alternative treatments. All completed the Beck Anxiety Inventory and the Rotter Locus of Control scale. Negative first experiences with "uncaring, insensitive, and unnecessarily harsh" oncologists, fear of side effects, and belief in the efficacy of alternative therapies were key factors in the decision to reject potentially life-prolonging conventional therapy. Refusers differed from controls in their perceptions of the value of conventional treatment, believing that chemotherapy and radiotherapy were riskier (p communicate hope, educate them about their options, and allow them time to come to terms with their diagnosis before starting treatment might have led them to better treatment choices.

    Full Text Available Leading-edge therapeutic laser technologies are not available at every medical facility; therefore, alternative approaches incorporating novel advances in digital and laser technology into more readily available conventional methods have generated significant research interest. Using a rabbit model, this study investigated whether the algorithm used in the Endpoint Management (EM software system of the latest devices could enable subthreshold laser treatment in conventional retinal tissue laser therapy systems.Two types of devices were used, the PASCAL Streamline 577 and the MC 500-Vixi™, and the laser method was classified into three categories: EM; single-shot using PASCAL with arbitrary energy settings (PSS-SDM; and MC500-VixiTM (VX-SDM, which were performed in eight eyes from four Dutch-Belted rabbits. In EM, 100 mW (100% was set as a landmark, and the laser energy parameters were gradually decreased to 80%, 60%, 50%, 40%, 30%, 20%, and 10%, using a 2 × 3 square pattern. In PSS-SDM and VX-SDM, as control, the laser energy was gradually decreased to 100, 80, 60, 50, 40, 30, 20, and 10 mW. The laser settings were fixed at 200 μm, 20 ms, and a wavelength of 577 μm. To identify and compare the extent of tissue damage at each spot size, optical coherence tomography (OCT and histological findings were used to construct a three-dimensional histopathology image using a confocal laser scanning fluorescence microscope.The spot size at 50% setting on EM was 7183 μm2; PSS-SDM required 50 mW (5503 μm2 to 60 mW (10279 μm2 and VX-SDM required 50 mW (7423 μm2 to create the approximate spot size. Furthermore, at 50 mW of PSS-SDM and VX-SDM, the extent of tissue damage in all three methods was generally in accord with the outer nuclear layer by OCT and inner nuclear layer by histopathological imaging.These findings suggest that it may be possible to perform subthreshold laser therapy using approximations from the EM algorithm.

    Purpose: To assess the macroscopic hematuria rates within a single-institution randomized phase 3 trial comparing dose-escalated, conventionally fractionated radiation therapy (CFRT) and moderately hypofractionated radiation therapy (MHRT) for localized prostate cancer. Methods and Materials: Patients with intermediate- to high-risk localized prostate cancer were treated with conformal RT and short-course androgen deprivation. Both the prostate and the entire seminal vesicles were treated to 80 Gy in 40 fractions over 8 weeks (CFRT) or 62 Gy in 20 fractions over 5 weeks (MHRT). The endpoint of the present study was the development of any episode or grade of macroscopic hematuria. The median follow-up period was 93 months (range 6-143). Results: Macroscopic hematuria was reported by 25 of 168 patients (14.9%). The actuarial estimate of hematuria at 8 years was 17.0% (95% confidence interval [CI] 10.7%-23.3%). The number of patients with hematuria was 6 and 19 in the CFRT and MHRT arms, respectively, for an actuarial 8-year estimate of 9.7% and 24.3%, respectively (hazard ratio 3.468, 95% CI 1.385-8.684; P=.008). Overall, 8 of 25 patients were found to have biopsy-proven urothelial carcinoma (3 in the CFRT arm and 5 in the MHRT arm; P=.27). Thus, the 8-year actuarial incidence of macroscopic hematuria (after censoring urothelial cancer–related episodes) was 4.1% and 18.2% after CFRT and MHRT, respectively (hazard ratio 4.961, 95% CI 1.426-17.263; P=.012). The results were confirmed by multivariate analysis after accounting for several patient-, treatment-, and tumor-related covariates. Conclusions: MHRT was associated with a statistically significant increased risk of macroscopic hematuria compared with CFRT.

    Background and purpose: proton therapy for uveal melanoma provides high-conformal dose application to the target volume and, thus, an optimal saving of the organs at risk nearby. Treatment planning is done with the model-based treatment-planning system eyeplan. Tumor reconstruction is based only on a fundus composite, which often leads to an overestimation of the clinical target volume (CTV). The purpose was to exploit MRI on trial in a proton therapy-planning system by using the novel image-based treatment-planning system octopus. Patients and methods: ten patients with uveal melanomas received both a high-resolution planning CT and MRI of the eye. MR examinations were made with an eye coil. Eyeplan requires eye geometry data for modeling, and tantalum marker clips for submillimeter positioning and additional information from ultrasound and 3-D imaging. By contrast, octopus provides the full integration of 3-D imaging (e.g., CT, MRI). CTVs were delineated in each slice. For all patients, CTVs (eyeplan vs. octopus) were compared intraindividually. Results: octopus planning led to a mean reduction of the target volume by a factor of 1.7 (T1-weighted [T1w]) and 2.2 (T2w) without compromising safety. The corresponding field size could be scaled down on average by a factor of 1.2 (T1w) and 1.4 (T2w), respectively. Conclusion: compared with the conventional eyeplan, MRI-based treatment planning of ocular tumors with octopus could be a powerful tool for reducing the CTV and, consequently, the treatment volume and the field size. This might be translated into a better patient compliance during treatment and a decreased late toxicity. (orig.)

    Summary Osteoarthritis (OA) is a chronic degenerative joint disease characterized by pain and progressive functional limitation. Viscosupplementation with intra-articular (IA) hyaluronic acid (HA) could be a treatment option in OA, however recommendations made in different international guidelines for the non-surgical management of OA are not always concordant with regard to the role of IA injection therapies. Results from a recent Italian Consensus Conference underline how IA-HA to treat OA represents a widely used therapy in Italy. Specifically high molecular weight HA, cross-linked HA, and mobile reticulum HA are considered very useful to treat the OA joints from a great number of expert in Italy. These kinds of HA could reduce the NSAIDs intake, furthermore high-molecular weight and mobile reticulum HA are considered to be able to delay or avoid a joint prosthetic implant. This mini review highlights the results obtained from the Italian Consensus Conference “Appropriateness of clinical and organizational criteria for intra-articular injection therapies in osteoarthritis” and give further indication about innovation in IA-HA therapies.

    Purpose: Fractionated external beam radiotherapy (EBRT) ± carmustine (BCNU) is the standard of care for patients with glioblastoma multiforme (GBM), but survival results remain poor. Preclinical studies indicate synergy between RT and paclitaxel (TAX) in astrocytoma cell lines. Phase I studies in GBM have demonstrated a maximum tolerated dose for TAX of 225 mg/m 2 /3 h/week x 6, during EBRT, with no exacerbation of typical RT-induced toxicities. The Radiation Therapy Oncology Group (RTOG) therefore mounted a Phase II study to determine the feasibility and efficacy of conventional EBRT and concurrent weekly TAX at its MTD. Patients and Methods: Sixty-two patients with histologic diagnosis of GBM were enrolled from 8/16/96 through 3/21/97 in a multi-institutional Phase II trial of EBRT and TAX 225 mg/m 2 /3 h (1-3 h before EBRT), administered the first treatment day of each RT week. Total EBRT dose was 60 Gy (200 cGy/fraction), 5 days per week. A smaller treatment field, to include gross disease plus a margin only, was used after 46 Gy. Results: Sixty-one patients (98%) were evaluable. Median age was 55 years (range, 28-78). Seventy-four percent were ≥50 years. Recursive partitioning analysis (RPA) Classes III, IV, V, VI included 10 (17%), 21 (34%), 25 (41%), and 5 (8%) patients, respectively. Gross total resection was performed in only 16%. There was no Grade 3 or 4 neutropenia or thrombocytopenia. Hypersensitivity reactions precluding further use of TAX occurred in 4 patients. There were 2 instances of late neurotoxicity (4% Grade 3 or 4). Ninety-one percent of patients received treatment per protocol. Seventy-seven percent completed prescribed treatment (6 weeks). Of 35 patients with measurable disease, CR/PR was observed in 23%, MR in 17%, and SD in 43%. Seventeen percent demonstrated progression at first follow-up. Median potential follow-up time is 20 months. Median survival is 9.7 months, with median survivals for RPA classes III, IV, V, and VI of 16.3, 10

    Objective. To compare the evaluation of fractures of the distal radius with MRI and conventional radiographs. To demonstrate the ability of MRI to detect unsuspected soft tissue derangement accompanying this common injury. Design and patients. Twenty-one consecutive inpatients admitted following fracture of the distal radius underwent preoperative evaluation with both conventional radiographs and MRI. In each case, analysis was made of both the osseous and soft tissue injury. MRI findings were compared with those identified on conventional radiographs and at subsequent surgical fixation. Results. Of 21 patients with fractures of the distal radius, 20 had extension to the radiocarpal articulation, 14 had distal radio-ulnar joint extension and 5 had avulsion of the ulnar styloid.Occult carpal bone fractures accompanying fracture of the distal radius were identified in two patients: one of the capitate and the other of the second metacarpal base. Ten patients (48%) had associated soft tissue injury: six patients had scapholunate ligament rupture, two patients had disruption of the triangular fibrocartilage, one patient had extensor carpi ulnaris tenosynovitis and one patient had a tear of a dorsal radiocarpal ligament. Of five patients with ulnar styloid avulsions, none had evidence of triangular fibrocartilage tears. Conclusion. MRI affords better evaluation of osseous injury accompanying distal radial fractures than conventional radiographs. Intra-articular soft tissue injury accompanies distal radial fractures in almost 50% of cases. Scapholunate ligament disruption commonly accompanies intra-articular fracture through the lunate facet of the distal radius. Fracture of the ulnar styloid is infrequently associated with tear of the triangular fibrocartilage. (orig.)

    Full Text Available Moxibustion therapy has been used in East Asian medicine for more than a thousand years. However, there are some problems associated with this therapy in clinical practice. These problems include lack of control over the treatment temperature, emission of smoke, and uneven temperature distribution over the treatment region. In order to resolve these problems, we developed a precise temperature-control device for use as an alternate for conventional moxibustion therapy. In this paper, we describe the treatment of a single patient with paralytic ileus that was treated with moxibustion. We also describe an evaluation of temperature distribution on the skin surface after moxibustion therapy, the development of a heat-transfer control device (HTCD, an evaluation of the HTCD, and the clinical effects of treatment using the HTCD. The HTCD we developed can heat the skin of the treatment region uniformly, and its effect may be equivalent to conventional moxibustion, without the emission of smoke and smell. This device can be used to treat ileus, abdominal pain, and coldness of abdomen in place of conventional moxibustion in modern hospitals.

    Purpose: Despite conventional radiation therapy, 54 Gy in single doses of 1.8 Gy (54/1.8 Gy) over 6 weeks, most children with diffuse intrinsic pontine glioma (DIPG) will die within 1 year after diagnosis. To reduce patient burden, we investigated the role of hypofractionation radiation therapy given over 3 to 4 weeks. A 1:1 matched-cohort analysis with conventional radiation therapy was performed to assess response and survival. Methods and Materials: Twenty-seven children, aged 3 to 14, were treated according to 1 of 2 hypofractionation regimens over 3 to 4 weeks (39/3 Gy, n=16 or 44.8/2.8 Gy, n=11). All patients had symptoms for {<=}3 months, {>=}2 signs of the neurologic triad (cranial nerve deficit, ataxia, long tract signs), and characteristic features of DIPG on magnetic resonance imaging. Twenty-seven patients fulfilling the same diagnostic criteria and receiving at least 50/1.8 to 2.0 Gy were eligible for the matched-cohort analysis. Results: With hypofractionation radiation therapy, the overall survival at 6, 9, and 12 months was 74%, 44%, and 22%, respectively. Progression-free survival at 3, 6, and 9 months was 77%, 43%, and 12%, respectively. Temporary discontinuation of steroids was observed in 21 of 27 (78%) patients. No significant difference in median overall survival (9.0 vs 9.4 months; P=.84) and time to progression (5.0 vs 7.6 months; P=.24) was observed between hypofractionation vs conventional radiation therapy, respectively. Conclusions: For patients with newly diagnosed DIPG, a hypofractionation regimen, given over 3 to 4 weeks, offers equal overall survival with less treatment burden compared with a conventional regimen of 6 weeks.

    The therapeutic efficacy of photoradiation therapy (PRT) following hematoporthyrin derivative (HpD) administration was compared in the experimental MS-2 tumour model to that of conventional treatment methods for local control of neoplastic diseases (i.e. surgery and radiotherapy). The therapeutic effects of PRT and surgical removal of primary tumour were comparable in these experiments. However, optimal effects were critically dependent on the stage of tumour development. In addition, the therapeutic advantage of PRT over radiotherapy suggests an interesting role of a new approach in tumours resistant to this conventional treatment. (author)

    To compare acute/late toxicity and biochemical control in contemporaneous prostate cancer patient cohorts treated with hypofractionated postprostatectomy radiation therapy (hypoPORT) or conventional PORT (coPORT). Consecutive patients treated with intensity modulated hypoPORT (2.5 Gy per fraction, median cumulative dose 65 Gy [range, 57.5-70 Gy]) or coPORT (1.8-2.0 Gy per fraction, median cumulative dose 66 Gy [range, 60-74 Gy]) between 2005 and 2016 at 2 institutions constituted the study cohort. Acute toxicity and cumulative late grade 2 and ≥3 genitourinary (GU) and gastrointestinal (GI) toxicity incidences were calculated for all patients using the Kaplan-Meier method and compared between cohorts. Biochemical progression-free survival (bPFS) was calculated in patients with ≥12 months' follow-up. Median follow-up for all 461 patients was 38.6 months. Of the 461 patients, 167 (36%) received hypoPORT, and 294 (64%) patients received coPORT. The hypoPORT cohort had significantly worse baseline urinary incontinence. Acute grade ≥2 GU toxicity was more common after hypoPORT (22% vs 8%) (P = .0001). Late grade ≥3 GU toxicity cumulative incidence at 6 years was 11% (hypoPORT) and 4% (coPORT) (P = .0081). However, hypoPORT was not associated with late grade ≥2 GU toxicity on multivariate analysis (hazard ratio 1.39, 95% confidence interval 0.86-2.34) (P = .18). There was no difference in acute or late GI toxicity. In the subset of patients with ≥12 month's follow-up (n = 364, median follow-up 52 months), 4-year bPFS was 78% (95% CI 69.4-85.0) after hypoPORT (P = .0038) and 65% (95% CI 57.6-71.1) after coPORT. HypoPORT was not significant for bPFS on multivariate analysis (hazard ratio 0.64, 95% CI 0.41-1.02, P = .059). HypoPORT shows promising early biochemical control. After controlling for baseline urinary function, hypoPORT was not associated with greater GU toxicity than coPORT. © 2018 Elsevier Inc. Copyright © 2018 Elsevier Inc. All

    BNCT is an experimental radiotherapeutic modality that uses the capacity of the isotope 10 B to capture thermal neutrons leading to the production of 4 He and 7 Li, particles with high linear energy transfer (LET). The aim was to evaluate and compare in vitro the mechanisms of response to the radiation arising of BNCT and conventional gamma therapy. We measured the survival cell fraction as a function of the total physical dose and analyzed the expression of p27/Kip1 and p53 by Western blotting in cells of colon cancer (ARO81-1). Exponentially growing cells were distributed into the following groups: 1) BPA (10 ppm 10 B) + neutrons; 2) BOPP (10 ppm 10 B) + neutrons; 3) neutrons alone; 4) gamma-rays. A control group without irradiation for each treatment was added. The cells were irradiated in the thermal neutron beam of the RA-3 (flux= 7.5 10 9 n/cm 2 sec) or with 60 Co (1Gy/min) during different times in order to obtain total physical dose between 1-5 Gy (±10 %). A decrease in the survival fraction as a function of the physical dose was observed for all the treatments. We also observed that neutrons and neutrons + BOPP did not differ significantly and that BPA was the more effective compound. Protein extracts of irradiated cells (3Gy) were isolated to 24 h and 48 h post radiation exposure. The irradiation with neutrons in presence of 10 BPA or 10 BOPP produced an increase of p53 at 24 h maintain until 48 h. On the contrary, in the groups irradiated with neutrons alone or gamma the peak was observed at 48 hr. The level of expression of p27/Kip1 showed a reduction of this protein in all the groups irradiated with neutrons (neutrons alone or neutrons plus boron compound), being more marked at 24 h. These preliminary results suggest different radiobiological response for high and low let radiation. Future studies will permit establish the role of cell cycle in the tumor radio sensibility to BNCT. (author)

    Background: Hepatitis is a major public health problem in Pakistan due to its strong association with liver failure and hepatocellular carcinoma. In Pakistan, conventional interferon therapy along with Ribavirin is favoured especially in Government funded programs for treatment of Hepatitis C, over the more expensive Pegylated Interferon and Ribavirin combination therapy as recommended by Pakistan society of Gastroenterology and GI endoscopy due to its favourable results observed in genotype 3 which is the dominant genotype of this region. Objective of our study was to assess the viriological responses with standard interferon therapy and to determine the predictive values of early viriological response (EVR) for Sustained Viriological Response (SVR) in chronic hepatitis C patients treated with standard interferon therapy. Methods: A cross sectional study was conducted on patients with chronic hepatitis C having received standard interferon and ribavirin therapy for six months. EVR and SVR were noted for analysis. Positive and negative predictive values of EVR on SVR were calculated. Results: Out of the total sample (N=3075), 1946 (63.3 percentage) patients were tested for EVR. 1386 (71.2 percentage) were positive while 560 (28.8 percentage) were negative while 516 (16.8 percentage) were tested for SVR. Two hundred and eighty-five (55.2 percentage) were positive while 231 (44.8 percentage) were negative. EVR and SVR tested were N=117. Positive predictive value of EVR on SVR was 67.1 percentage and negative predictive value was 65.8 percentage. Statistically significant association between EVR and SVR was determined with Chi square statistic of 11.8 (p-value <0.0001). Conclusion: EVR is a good predictor of response of patients to standard interferon and ribavirin therapy. In the absence of an EVR, it seems imperative to stop further treatment. Virilogical responses with conventional interferon therapy are comparable to those of pegylated interferon therapy so

    Background and purpose: Nasopharyngeal carcinoma (NPC) is generally responsive to radiation therapy. However therapeutic results after conventional radiotherapy remain relatively poor especially for patients with locoregional advanced NPC. The aim of this study was to evaluate the impact of a split course bifractionated radiotherapy regimen in a phase III randomised trial. Patients and methods: From January 1997 to September 2003, 154 patients with M0 histologically proven NPC were treated in our institution. They were staged according to the American Joint Committee on Cancer - International Union Against Cancer (AJCC-UICC) 1986 TNM classification. Patients with locally advanced nodal disease (N2-N3) received induction chemotherapy. All patients were randomised to receive either conventional radiotherapy at 2 Gy/fraction/day, 5 days/week to 70 Gy/7 weeks or split course bifractionated radiotherapy at 1.6 Gy/fraction, twice daily, 5 days/week to 70.4 Gy/6 weeks. Response and toxicity were evaluated according to the WHO and RTOG criteria. Results: Patients were well balanced between the two arms. The complete remission rate was 91% in conventional radiotherapy arm and 93% in bifractionated radiotherapy arm (p = 0.3). There was more grade II-III skin fibrosis in experimental arm with a 5 year actuarial probability of 66% vs 52% (p = 0.04). Locoregional and distant relapses occurred in 34% of cases in conventional arm and 38% in experimental arm (p = 0.28). With a median follow-up of 56 months, the 5 year overall survival and the disease free survival rates were, respectively (71% and 61%), in conventional arm and (62% and 60%) in bifractionated arm, the difference being statistically non significant. Comments: The present trial comparing conventional radiotherapy to a split course bifractionated radiation therapy failed to demonstrate significant improvement in locoregional control and survival in experimental arm which was associated with more grade II-III skin

    The Nintendo® Wii is a simple and affordable virtual therapy alternative. It may be used at home, and it is a motivating recreational activity that provides continuous feedback. However, studies comparing the use of the Nintendo® Wii to conventional physical therapy are needed. To compare the effect of a rehabilitation treatment using the Nintendo® Wii (NW) with conventional physical therapy (CPT) to improve the sensorimotor function and quality of life for post-stroke hemiparetic patients. The present study applied a randomized, blind, and controlled clinical trial. In total, 30 patients with post-stroke hemiparesis were evaluated. A total of 15 patients were randomly assigned to each group. The SF-36 quality of life and Fugl-Meyer scales were used to evaluate the patients. After treatment, the only variable that differed between the groups was the physical functioning domain of the SF-36 in the group that received conventional physical therapy. A significant difference was observed between both groups before and after treatment in terms of the following Fugl-Meyer scale items: passive movement and pain, motor function of the upper limbs (ULs), and balance. The CPT group also showed a significant difference with regard to their UL and lower limb (LL) coordination. The SF-36 scale analysis revealed a significant difference within both groups with regard to the following domains: physical functioning, role limitation due to physical aspects, vitality, and role limitation due to emotional aspects. The NW group also exhibited a significant difference in the mental health domain. The results indicate that both approaches improved the patients' performance in a similar manner. Virtual rehabilitation using the Nintendo Wii® and CPT both effectively treat post-stroke hemiparetic patients by improving passive movement and pain scores, motor function of the upper limb, balance, physical functioning, vitality, and the physical and emotional aspects of role functioning.

    Full Text Available Background. Herb-derived compound andrographolide sulfonate (called Xiyanping injection recommended control measure for severe hand, foot, and mouth disease (HFMD by the Ministry of Health (China during the 2010 epidemic. However, there is a lack of good quality evidence directly comparing the efficacy of Andrographolide Sulfonate combination therapy with conventional therapy. Methods. 230 patients were randomly assigned to 7–10 days of Andrographolide Sulfonate 5–10 mg/Kg/day and conventional therapy, or conventional therapy alone. Results. The major complications occurred less often after Andrographolide Sulfonate (2.6% versus 12.1%; risk difference [RD], 0.94; 95% CI, 0.28–1.61; P=0.006. Median fever clearance times were 96 hours (CI, 80 to 126 for conventional therapy recipients and 48 hours (CI, 36 to 54 for Andrographolide Sulfonate combination-treated patients (χ2=16.57, P<0.001. The two groups did not differ in terms of HFMD-cause mortality (P=1.00 and duration of hospitalization (P=0.70. There was one death in conventional therapy group. No important adverse event was found in Andrographolide Sulfonate combination therapy group. Conclusions. The addition of Andrographolide Sulfonate to conventional therapy reduced the occurrence of major complications, fever clearance time, and the healing time of typical skin or oral mucosa lesions in children with severe HFMD.

    Dry cow therapy, administered at the end of lactation, is aimed at eliminating current and preventing future intramammary (IMM) bacterial infections and typically involves intramammary administration of antibiotics. Certified organic dairies in the United States are restricted from using antibiotics and must consider an alternative therapy or no dry cow therapy. The current study compared 2 herbal products to conventional dry cow therapy and no treatment for a total of 5 treatments over 2 trials. Trial 1 was conducted over 3 yr on 1 research farm and trial 2 included 4 commercial farms plus the research herd over 2 yr. Treatments included (1) a conventional IMM antibiotic and internal teat sealant (penicillin-dihydrostreptomycin and bismuth subnitrate; CON); (2) an herbal IMM product purported to act as a teat sealant (Cinnatube, New AgriTech Enterprises, Locke, NY; CIN); (3) an herbal IMM product (Phyto-Mast, Bovinity Health LLC, Narvon, PA; P-M); (4) Phyto-Mast and Cinnatube (PC); or (5) no dry cow therapy (NT). Each treatment group was balanced by breed, lactation number, due date, herd, and year. However, the CON treatment was used only in the research herd because of the intent to avoid antibiotic usage on the other 4 farms. Comparisons among treatments included the difference between pre- and posttreatment 305-d mature equivalent milk production (trial 1), somatic cell score change from dry-off to freshening at the cow and quarter levels (trials 1 and 2), and milk microbiology change over the dry period (trial 2). We detected no significant differences among treatments for milk yield differences between the lactation following treatment and the lactation preceding treatment. Changes in somatic cell score from one lactation to the next also did not differ significantly among treatments in either trial. Cure rates were not significantly different among treatments; only 19.6% of all quarters were infected at dry off. The proportion of quarters with new

    To examine whether converting from conventional Spinal Cord Stimulation (SCS) to High Density (HD) SCS reduces neuropathic pain over a period of 12 months in patients with failed SCS therapy. Retrospective, open label, single center, consecutive case series of 30 neuropathic pain patients (Failed Back Surgery Syndrome [FBSS], Complex Regional Pain Syndrome [CRPS], and polyneuropathy [NP]). Patients with an initial adequate response to conventional SCS, but in whom pain increased over time, were included (Numeric Rating Scales [NRS] >6). These patients were stimulated with HD-SCS parameters and followed-up for 12 months. We report pain intensity, measured with NRS, before SCS implantation, 1 and 3 months after starting SCS with conventional stimulation, and after 1, 6, and 12 months of HD SCS. Pain reduction with conventional stimulation was initially adequate (NRS mean 8.6 to 5.3 at three months postimplant) but increased over time to a mean NRS of 7.7 at the time of reprogramming. NRS scores decreased significantly to 4.3 (p = 0.015) after reprogramming from conventional SCS (30 Hz, 300 µsec, 3.0 V) to HD SCS (409 Hz, range 130-1000 Hz, 409 µsec, 2.4V) in the patients still using HD-SCS at 12 months. In the nonresponders (patients who stopped HD-SCS for any reason), 76% had a diagnosis of FBSS. Almost half of the patients aborting HD-SCS preferred to feel paresthesias despite better pain relief. There was a significant difference between nonresponders and responders regarding the amount of electrical energy delivered to the spinal cord. Neuropathic pain suppression is significantly enhanced after converting from failed conventional SCS to HD SCS in patients with FBSS, CRPS, and NP over a measured period of 12 months. There appears to be a dose-related response between the amount of energy delivered to the spinal cord and clinical effect. © 2016 International Neuromodulation Society.

    Despite the aging population, few studies have documented the treatment of geriatric psoriasis. The purpose of this study is to compare the efficacy, safety, and prescribing patterns of biologics and conventional systemic medications in elderly versus adult psoriasis. All patient visits coded for psoriasis or psoriatic arthritis (ICD-9 696.1 or 696.0) at the Tufts Medical Center General Dermatology Clinic from January 1, 2008, to March 1, 2015 were included in this retrospective cohort study. The outcome measure used was the validated simple-measure for assessing psoriasis activity (S-MAPA), the product of the physician's global assessment and the body surface area. 194 patients who underwent 278 treatment courses were included in the study. 48 patients were included in the elderly cohort (≥ 65 years old) and 146 in the adult cohort (18-64 years old). There was no significant difference in S-MAPA improvement at 12 weeks between the two cohorts when treated with biologics (42.92% improvement in adults, 48.77% in elderly; P=0.498) or conventional systemics (43.96% and 51.82%, respectively; P=0.448). Within the elderly cohort, there was no significant difference in efficacy of biologics versus conventional systemics at any time point. Topical prescription rates were significantly higher in the elderly cohort ( P=0.004) while biologic prescription rates were significantly lower ( P=0.014) despite the same baseline S-MAPA in both age groups. For both biologics and conventional systemics, there was no statistically significant intergroup difference in the rate of adverse events ( P=0.322 for biologics; P=0.581 for conventional systemics) or infection ( P=0.753 for biologics; P=0.828 for conventional systemics). Within the elderly cohort, there was a higher rate of adverse events with conventional systemic treatment than with biologic treatment ( P=0.033). This study provides preliminary evidence to suggest that biologic and conventional systemic therapies are similarly

    Aim: To determine when preoperative breast MRI will not be more informative than available breast imaging and can be omitted in patients eligible for breast conserving therapy (BCT). Methods: We performed an MRI in 685 consecutive patients with 692 invasive breast tumors and eligible for BCT based on conventional imaging and clinical examination. We explored associations between patient, tumor, and conventional imaging characteristics and similarity with MRI findings. Receiver operating characteristic (ROC) analysis was employed to compute the area under the curve (AUC). Results: MRI and conventional breast imaging were similar in 585 of the 692 tumors (85%). At univariate analysis, age (p < 0.001), negative preoperative lymph node status (p = 0.011), comparable tumor diameter at mammography and at ultrasound (p = 0.001), negative HER2 status (p = 0.044), and absence of invasive lobular cancer (p = 0.005) were significantly associated with this similarity. At multivariate analysis, these factors, except HER2 status, retained significant associations. The AUC was 0.68. Conclusions: It is feasible to identify a subgroup of patients prior to preoperative breast MRI, who will most likely show similar results on conventional imaging as on MRI. These findings enable formulation of a practical consensus guideline to determine in which patients a preoperative breast MRI can be omitted.

    To compare the effectiveness of antimicrobial photodynamic therapy (PDT), standard endodontic treatment and the combined treatment to eliminate bacterial biofilms present in infected root canals. Ten single-rooted freshly extracted human teeth were inoculated with stable bioluminescent Gram-negative bacteria, Proteus mirabilis and Pseudomonas aeruginosa to form 3-day biofilms in prepared root canals. Bioluminescence imaging was used to serially quantify bacterial burdens. PDT employed a conjugate between polyethylenimine and chlorin(e6) as the photosensitizer (PS) and 660-nm diode laser light delivered into the root canal via a 200-micro fiber, and this was compared and combined with standard endodontic treatment using mechanical debridement and antiseptic irrigation. Endodontic therapy alone reduced bacterial bioluminescence by 90% while PDT alone reduced bioluminescence by 95%. The combination reduced bioluminescence by >98%, and importantly the bacterial regrowth observed 24 hours after treatment was much less for the combination (Ptreatment. Bioluminescence imaging is an efficient way to monitor endodontic therapy. Antimicrobial PDT may have a role to play in optimized endodontic therapy. (c) 2006 Wiley-Liss, Inc.

    Radioisotope therapy began in 1942 with the use of 131 I for Graves disease and 32 P for polycythemia vera. Local therapy with radioisotopes includes radiocolloids for malignant pleural and peritoneal effusions, intra-articular radiocolloids for chronic synovitis, intra-arterial radioactive microspheres for liver metastases, and intralymphatic administration for malignancies of the lymphatic system. The most widely practised use of radioisotopes for therapy is for the management of hyperthyroidism by 131 I. 131 is also being used effectively for thyroid cancer, particularly at the Radiation Medicine Centre, BARC. There is hope that a new generation of radiolabelled compounds is round the corner for therapy. Radiolabelled monoclonal antibodies aimed against specific tumor antigens have already shown great promise. Another area of interest is the use of minute lipid spheroids (vesicles) enclosing the radioactive drug which can be targeted to the tumor. (author). 19 refs

    Full Text Available Fibromyalgia poses a challenge for therapy. Recent guidelines suggest that fibromyalgia should be treated within a multidisciplinary therapy approach. No data are available that evaluated multimodal treatment strategies of Integrative Medicine (IM. We conducted a controlled, nonrandomized pilot study that compared two inpatient treatment strategies, an IM approach that included fasting therapy and a conventional rheumatology (CM approach. IM used fasting cure and Mind-Body-Medicine as specific methods. Of 48 included consecutive patients, 28 were treated with IM, 20 with CM. Primary outcome was change in the Fibromyalgia Impact Questionnaire (FIQ score after the 2-week hospital stay. Secondary outcomes included scores of pain, depression, anxiety, and well being. Assessments were repeated after 12 weeks. At 2 weeks, there were significant improvements in the FIQ (P<0.014 and for most of secondary outcomes for the IM group compared to the CM group. The beneficial effects for the IM approach were reduced after 12 weeks and no longer statistically significant with the exception of anxiety. Findings indicate that a multimodal IM treatment with fasting therapy might be superior to CM in the short term and not inferior in the mid term. Longer-term studies are warranted to assess the clinical impact of integrative multimodal treatment in fibromyalgia.

    The treatment of angina pectoris as a symptom of coronary artery disease usually is focused on restoring the balance between oxygen demand and supply of the myocardium by administration of drugs interfering in heart rate, cardiac pre- and afterload, and coronary vascular tone. For nonresponders to drug therapy or for those with jeopardized myocardium, revascularization procedures such as coronary bypass surgery and percutaneous transluminal coronary angioplasty are at hand. However, the atherosclerotic process is not stopped by these therapies and, at longer terms, angina may recur. It is not always possible to revascularize all the patients who do not positively react to medical treatment. Those with angina, not responding to adequate medication and who are not suitable anymore for revascularization, are considered to suffer from refractory angina pectoris. This group of patients has a poor quality of life, for their exercise tolerance is severely afflicted. For these patients, neurostimulation has been described repeatedly as an effective and safe therapy. The mechanism of action of neurostimulation is not completely known, but recent studies suggest an anti-ischemic effect, exerted through changes in myocardial blood flow. As soon as its safety is sufficiently established, it may become a useful alternative in the treatment of refractory angina pectoris.

Methods. Patients with intermediate to high risk for PPC were enrolled in this study. Subjects were randomly assigned to HFNC group (HFNCG or conventional oxygen group (COG following extubation. Arterial blood samples were collected after extubation at 1, 2, 6, 12, 24, 48, and 72 h. Patients with postoperative hypoxemia and PPC were recorded. Adverse events were also documented. Results. Totally 110 patients were randomly assigned to HFNCG (n=56 and COG (n=54. The occurrence rate of hypoxemia in COG was twice more than that in HFNCG (29.62% versus 12.51%, P0.05. Adverse effects as throat and nasal pain occurred more frequently in COG. Conclusions. HFNC application improves oxygenation and reduces the risk of reintubation following thoracoscopic lobectomy but cannot decrease the incidence of PPC.

    A 19-year-old man presented with an elastofibroma in his left shoulder joint. The patient had had limitation of motion in his left arm for 3 years, especially when rotating internally. Radiography of his left shoulder showed bone erosion in the neck of the humerus. On MR imaging, a soft tissue mass was noted in the shoulder joint eroding bone. The mass showed similar signal intensity to that of surrounding muscles on T1- and T2-weighted images. At surgery, a soft, encapsulated mass was found attached to the subscapularis muscle. It was pathologically confirmed as an elastofibroma. This unusual manifestation of an elastofibroma is discussed. (orig.)

    Contrary to common belief of clinicians that hemorrhagic stroke survivors have better functional prognoses than ischemic, recent studies show that ischemic survivors could experience similar or even better functional improvements. However, the influence of stroke subtype on gait and posture outcomes following an intervention blending conventional physiotherapy with robotic-assisted gait therapy is missing. This study compared gait and posture outcome measures between ambulatory hemorrhagic patients and ischemic patients, who received a similar 4 weeks' intervention blending a conventional bottom-up physiotherapy approach and an exoskeleton top-down robotic-assisted gait training (RAGT) approach with Lokomat. Forty adult hemiparetic stroke inpatient subjects were recruited: 20 hemorrhagic and 20 ischemic, matched by age, gender, side of hemisphere lesion, stroke severity, and locomotor impairments. Functional Ambulation Category, Postural Assessment Scale for Stroke, Tinetti Performance Oriented Mobility Assessment, 6 Minutes Walk Test, Timed Up and Go and 10-Meter Walk Test were performed before and after a 4-week long intervention. Functional gains were calculated for all tests. Hemorrhagic and ischemic subjects showed significant improvements in Functional Ambulation Category (Pbenefits from the same type, length and frequency of blended conventional physiotherapy and RAGT protocol. The use of intensive treatment plans blending top-down physiotherapy and bottom-up robotic approaches is promising for post-stroke rehabilitation.

    Full Text Available Abstract Background While conventionally fractionated radiation therapy alone is an acceptable option for poor prognostic patients with unresectable stage III NSCLC, we hypothesized that accelerated hypofractionated radiotherapy will have similar efficacy without increasing toxicity. Methods This is a retrospective analysis of 300 patients diagnosed with stage III NSCLC treated between 1993 and 2009. Patients included in the study were medically or surgically inoperable, were free of metastatic disease at initial workup and did not receive concurrent chemotherapy. Patients were categorized into three groups. Group 1 received 45 Gy in 15 fractions over 3 weeks (Accelerated Radiotherapy (ACRT while group 2 received 60-63 Gy (Standard Radiation Therapy 1 (STRT1 and group 3 received > 63 Gy (Standard Radiation Therapy (STRT2. Results There were 119 (39.7% patients in the ACRT group, 90 (30.0% in STRT1 and 91 (30.3% in STRT2. More patients in the ACRT group had KPS ≤ 60 (p 5% (p = 0.002, and had stage 3B disease (p Conclusions Despite the limitations of a retrospective analysis, our experience of accelerated hypofractionated radiation therapy with 45 Gy in 15 fractions appears to be an acceptable treatment option for poor performance status patients with stage III inoperable tumors. Such a treatment regimen (or higher doses in 15 fractions should be prospectively evaluated using modern radiation technologies with the addition of sequential high dose chemotherapy in stage III NSCLC.

    Musculoskeletal problems have become a significant issue in the profession of dentistry. There are currently no recommended effective disease-preventing and modifying remedies. High prevalence rates for musculoskeletal disorders (MSDs) among dentists have been reported in the literature. Complementary and alternative medicine can be helpful in managing and preventing the MSDs. The purpose of this study was to determine if dentists in the western part of India are using complementary and alternative medicine therapies for MSDs, and also to find if those who use complementary and alternative medicine therapies have greater job/career satisfaction compared to conventional therapy (CT) users. Dentists of western India registered under the Dental Council of India (N = 2166) were recruited for the study. Data were analyzed using univariate and bivariate analyses and logistic regression. A response rate of 73% (n = 1581) was obtained, of which 79% (n = 1249) was suffering from MSDs. The use of complementary and alternative medicine or CT was reported by 90% (n = 1124) of dentists with MSDs. Dentists using complementary and alternative medicine reported greater health (P alternative medicine therapies may improve the quality of life and enhance job satisfaction for a dentist who suffers from MSDs.

  2. Fifty years of advances in sarcoma treatment: moving the needle from conventional chemotherapy to targeted therapy.

    2014-01-01

    Much of the progress in systemic therapy for sarcomas was accomplished in the first half of the last 5 decades. Various chemotherapeutic agents were tested in the 70s through the 80s and became part of the standard of care for this patient population. During the decade of the 90s, dose intensification became feasible as a result of improved supportive care and the availability of growth factors, thus maximizing the therapeutic potential of this class of agents. However, response rates and survival plateaued and it became obvious that newer and mechanistically different agents were needed to improve the therapeutic index and gain further enhancement of outcomes. Since early 2000, primarily inspired by the experience with imatinib in gastrointestinal stromal tumors (GISTs), several targeted therapies have been tested in sarcomas with modest success. The major limitations encountered include the lack of drivers and actionable targets for bone and soft tissue sarcomas with complex genomic profiles. Continued investigations and sequencing of larger numbers of these rare and heterogeneous malignancies could shed some light on a path toward improved outcomes.

    After a preliminary dose-finding study involving 12 patients with advanced or locally recurrent head and neck cancer, 27 patients were treated on a phase II protocol, using fluorouracil 350 mg/m2/d by continuous intravenous (IV) infusion over 5 days, followed on the sixth day by a 2-hour IV infusion of cisplatin 50 mg/m2, administered during the first and fourth weeks of radiation therapy to total doses between 60 and 64 Gy, using 2 Gy daily fractions. Eight of these 27 patients had American Joint Committee on Cancer Staging (AJCC) stage III disease, and 12 had stage IV disease. Four had recurrent disease after surgery. Three-year follow-up is now available. Twenty-one (77.8%) remitted completely following treatment, and 11 remain free of local and regional relapse at 3 years. Four have developed systemic metastases. Following successful salvage treatment in two cases, estimated determinate survival at 3 years is 64%. Acute toxicity was manageable with this regime. Eleven instances of grade 3 Radiation Therapy Oncology Group/European Organization for Research and Treatment of Cancer (RTOG/EORTC) mucositis were observed, which caused interruptions to radiotherapy in only four cases. No late sequelae have so far been recorded. It is concluded that the protocol described is tolerable but probably did not cause a greater number of locoregional cures than would have been expected following conventional radiotherapy alone in this group of patients. The use of infusional fluorouracil with concurrent conventionally fractionated radiation therapy and cisplatin infusion results in mucositis that limits the dose of fluorouracil to levels that are probably subtherapeutic.

    Purpose: To assess the effect of radiation therapy on lung function over the course of 3 years. Methods and Materials: Evolution of restrictive and obstructive lung function parameters was investigated in 108 breast cancer participants in a randomized, controlled trial comparing conventional radiation therapy (CR) and hypofractionated tomotherapy (TT) (age at inclusion ranging 32-81 years). Spirometry, plethysmography, and hemoglobin-corrected diffusing capacity were assessed at baseline and after 3 months and 1, 2, and 3 years. Natural aging was accounted for by considering all lung function parameters in terms of percent predicted values using the most recent reference values for women aged up to 80 years. Results: In the patients with negligible history of respiratory disease or smoking (n=77), the greatest rate of functional decline was observed during the initial 3 months, this acute decrease being more marked in the CR versus the TT arm. During the remainder of the 3-year follow-up period, values (in terms of percent predicted) were maintained (diffusing capacity) or continued to decline at a slower rate (forced vital capacity). However, the average decline of the restrictive lung function parameters over a 3-year period did not exceed 9% predicted in either the TT or the CR arm. Obstructive lung function parameters remained unaffected throughout. Including also the 31 patients with a history of respiratory disease or more than 10 pack-years showed a very similar restrictive pattern. Conclusions: In women with breast cancer, both conventional radiation therapy and hypofractionated tomotherapy induce small but consistent restrictive lung patterns over the course of a 3-year period, irrespective of baseline respiratory status or smoking history. The fastest rate of lung function decline generally occurred in the first 3 months.

    Purpose: To evaluate the efficacy of conventional radiotherapy for reducing tumor size and endocrine hypersecretion of pituitary adenomas. Methods and Materials: We reviewed the records of 91 patients with pituitary adenoma, who were first treated between 1969 and 1994 and had been followed for more than 2 years (median, 8.2 years.) Of these patients, 86 had received postoperative radiotherapy, and 5 had received radiotherapy alone. The median total dose was 51 Gy. Clinical symptoms related to mass effects or endocrine hypersecretion were assessed. The efficacy of radiotherapy was evaluated before treatment and during the follow-up period (1-14 years; median, 3 years) by estimating tumor size on computed tomography or magnetic resonance imaging in 56 patients, as well as by endocrine testing in the 22 patients who had secreting adenomas. Local control rate, prognostic factors, and side effects were analyzed. Results: Mass-effect symptoms improved in 72% and 79% of patients who had such symptoms due to nonsecreting adenomas and secreting adenomas, respectively. Symptoms of endocrine hypersecretion abated in 67% of patients who had such symptoms. Excessive hormone levels normalized in 74% of patients who showed endocrine hypersecretions. The greatest size reduction was seen 3 years after the completion of radiotherapy (24% CR, 62% PR, 12% NC, and 3% PD in nonsecreting adenomas, and 32% CR, 36% PR, 27% NC, and 5% PD in secreting adenomas). Three patients with secreting adenomas (2 with prolactinoma and 1 with Cushing's disease) showed a mismatch between reduction in tumor size and normalization of endocrine hypersecretion. The 10-year local control rates were 98%, 85%, 83%, and 67% for nonsecreting adenoma, growth-hormone-secreting adenoma, prolactinoma, and Cushing's disease, respectively. Univariate analyses showed that disease type and radiation field size were significant prognostic factors. Brain necrosis occurred in 1 patient who received a 60-Gy dose of

    To investigate the effectiveness of isolated eccentric versus conventional exercise therapy in patients with rotator cuff tendinopathy. Thirty-six patients with rotator cuff tendinopathy, diagnosed by an orthopaedic surgeon, were included and randomly allocated to an isolated eccentric exercise (EE) group (n = 20, mean age = 50.2 ± 10.8 years) or a conventional exercise (CG) group (n = 16, mean age = 48.6 ± 12.3 years). Both groups fulfilled a 12-week daily home-based exercise programme and received a total amount of nine treatment sessions. The Constant Murley score was used to evaluate both objective (e.g. range of motion and strength) and subjective measures (e.g. pain and activities of daily living). A visual analogue scale (VAS) was used to evaluate pain during daily activities. As secondary outcomes, shoulder range of motion and isometric abduction strength in 45° in the scapular plane were evaluated. All measurements were taken at baseline, at 6, 12 and 26 weeks. After 26 weeks, both groups showed a significant increase in the Constant Murley score and a significant decrease in VAS scores. No difference was found between the groups, for any of the evaluated outcome measures. A 12-week-isolated eccentric training programme of the rotator cuff is beneficial for shoulder function and pain after 26 weeks in patients with rotator cuff tendinopathy. However, it is no more beneficial than a conventional exercise programme for the rotator cuff and scapular muscles. Based on the results, clinicians should take into account that performing two eccentric exercises twice a day is as effective as performing six concentric/eccentric exercises once a day in patients with rotator cuff tendinopathy.

    The discovery of penicillin nearly 90 years ago revolutionized the treatment of bacterial disease. Since that time, numerous other antibiotics have been discovered from bacteria and fungi, or developed by chemical synthesis and have become effective chemotherapeutic options. However, the misuse of antibiotics has lessened the efficacy of many commonly used antibiotics. The emergence of resistant strains of bacteria has seriously limited our ability to treat bacterial illness, and new antibiotics are desperately needed. Since the discovery of penicillin, most antibiotic development has focused on the discovery of new antibiotics derived from microbial sources, or on the synthesis of new compounds using existing antibiotic scaffolds to the detriment of other lines of discovery. Both of these methods have been fruitful. However, for a number of reasons discussed in this review, these strategies are unlikely to provide the same wealth of new antibiotics in the future. Indeed, the number of newly developed antibiotics has decreased dramatically in recent years. Instead, a reexamination of traditional medicines has become more common and has already provided several new antibiotics. Traditional medicine plants are likely to provide further new antibiotics in the future. However, the use of plant extracts or pure natural compounds in combination with conventional antibiotics may hold greater promise for rapidly providing affordable treatment options. Indeed, some combinational antibiotic therapies are already clinically available. This study reviews the recent literature on combinational antibiotic therapies to highlight their potential and to guide future research in this field. PMID:28989242

    The treatment options for patients with non metastatic prostate cancer range from observation, radical prostatectomy, radiation therapy, hormonal therapy to various combination of some to all of them. Objective: we evaluated the impact on biochemical control of disease (bNED), acute and late intestinal (GI) and urological (GU) morbidity for a group of patients older than 70 years presenting initial or locally advanced prostate cancer treated with fractionated high dose rate brachytherapy (HDRB) as a boost to conventional external beam radiation therapy (RT) at the Department of Radiation Oncology from Hospital do Cancer A. C. Camargo, Sao Paulo, Brazil. Methods: a total of 56 patients older than 70 were treated from March, 1997 to June, 2002. All patients had prior to HDRB a course of RT to a median dose of 45 Gy. HDRB doses ranged from 16 Gy to 20 Gy, given in 4 fractions. Results: the median age of the patients was 74.4 years (range 70-83) and the median follow-up 33 months (range 24 to 60). The 5-year actuarial bNED rate was 77%. Acute GU and GI morbidity G1-2 were seen in 17.8% and 7.1% of patients, respectively. Late G1 or G2 GU morbidity was seen in 10.7% of the patients, while late G3 morbidity was observed in 7.1% of the patients, represented by urethral strictures. Conclusion: this group of patients had similar bNED rates when compared to literature, with acceptable morbidity rates. (author)

    Objective: To observe the therapeutic effect of three-dimensional conformal radiation therapy (3DCRT) for nasopharyngeal carcinoma (NPC). Methods: 78 patients with NPC was treated by radiation schedule in two phases. In the first phase, nasopharyngeal lesions and metastases of all patients were treated by three-dimensional conformal radiation therapy (3DCRT) with a fraction of 2-5 Gy daily, 5 day per weeks, total dose 30 Gy. The second phase T1N0 or parts of T2N0 patients were done by Conventional radiotherapy with total dose 55 Gy on two small lateral opposing fields + with total dose 50 Gy on neck on tangential field,adding a 3 cm block. Patients with lymph node metastasis were given 55 Gy on the dacio-neck field (After 40 Gy, two small lateral opposing fields were used to boost the primary tumor while the spinal cord shielded) + with total dose 55 Gy on lower neck on tangential field. The upper bound of designed therapeutic field was set to connect with lower bound of main therapeutic field. Results: Three months after treatment,the rate of CR, PR, SD, PD were 38.5%, 55.1%, 5.1%, 1.3%, Total effective rate (CR+PR) were 93.6%. The 1-year, 2-year, 3-year and 5-year local-regional control rates were 92.3%, 88.5%, 78.2%, 70.5%.The 1-year, 2-year , 3-year and 5-year overall survival rate were 96.2%, 89.7%, 83.3%, 71.8%. Appearing early radiation response is well tolerated and no obviously mouth difficulties and cranial nerve damage observed. Conclusion: Clinical result of early-course three-dimensional conformal radiation therapy (3DCRT) for nasopharyngeal carcinoma (NPC) is good. (authors)

    The increased beam-on times which characterize intensity-modulated radiation therapy (IMRT) could lead to an increase in the dose received by radiation therapists due to induced activity. To examine this, gamma ray spectrometry was used to identify the major isotopes responsible for activation at a representative location in the treatment room of an 18 MV accelerator (Varian Clinac 21EX). These were found to be 28 Al, 56 Mn, and 24 Na. The decay of the dose rate measured at this location following irradiation was analyzed in terms of the known half-lives to yield saturation dose rates of 9.6, 12.4, and 6.2 μSv/h, respectively. A formalism was developed to estimate activation dose (μSv/week) due to successive patient irradiation cycles, characterized by the number of 18 MV fractions per week, F, the number of MU per fraction, M, the in-room time between fractions, t d (min), and the treatment delivery time t r ' (min). The results are represented by the sum of two formulas, one for the dose from 28 Al≅1.8x10 -3 F M (1-e -0.3t r ' )/t r ' and one for the dose from the other isotopes ≅1.1x10 -6 F 1.7 Mt d . For conventional therapy doses are about 60 μ Sv/week for an 18 MV workload of 60 000 MU/week. Irradiation for QA purposes can significantly increase the dose. For IMRT as currently practiced, lengthy treatment delivery times limit the number of fractions that can be delivered per week and hence limit the dose to values similar to those in conventional therapy. However for an IMRT regime designed to maximize patient throughput, doses up to 330 μSv/week could be expected. To reduce dose it is recommended that IMRT treatments should be delivered at energies lower than 18 MV, that in multienergy IMRT, high-energy treatments should be scheduled in the latter part of the day, and that equipment manufacturers should strive to minimize activation in the design of high-energy accelerators

    Mycosis fungoides (MF) is the most prevalent subtype of cutaneous T-cell lymphoma, which is characterized by the proliferation of CD4 + T cells. While often an indolent disease, most patients eventually develop progression from isolated patches to tumors and finally nodal or visceral involvement. Treatment choice is largely based on disease burden, though prognostic factors such as disease stage, patient age, and extracutaneous involvement must be taken into consideration. Radiotherapy represents one of the most effective therapeutic modalities in the treatment of MF. Lymphocytes are exquisitely radiosensitive, and excellent responses are observed even with low doses of radiation. Total skin electron beam therapy (TSEBT) is a special technique that allows for the homogenous irradiation of the entire skin. There are well-documented radiation dose-response relationships for achieving a complete response. As such, TSEBT doses ≥ 30 Gy comprise the current standard of care. Although highly effective, most patients experience recurrent disease even after conventional-dose (≥ 30 Gy) TSEBT. In addition, toxicity is cumulatively dose dependent, and there is reluctance to administer multiple courses of conventional-dose TSEBT. Consequently, there has been renewed interest in determining the utility of TSEBT at lower total (≤ 30 Gy) doses. Advantages of low-total-dose (with standard dose per fraction) TSEBT include a shortened treatment course, the potential to minimize the risk of adverse events, and the opportunity to allow for retreatment in cases of disease recurrence. This comprehensive review compares the impact of different TSEBT dosing schemes on clinical outcomes of MF. Copyright © 2016 Elsevier Inc. All rights reserved.

    Migraine headaches are the most common acute and recurrent headaches. Current treatment of a migraine headache consists of multiple medications for control and prevention of recurrent attacks. Global emergence of alternative medicine led us to examine the efficacy of cupping therapy plus serkangabin syrup in the treatment of migraine headaches. This study was a randomized, controlled, open-label, comparative efficacy trial. We randomly assigned patients with migraine into cupping therapy plus serkangabin group (30 patients) and conventional treatment group (30 patients). An investigator assessed the severity of headache, frequency of attacks in a week and duration of attacks per hour in 5 visits (at the end of 2 weeks, 1, 3 and 6 months). Generalized estimating equations approach was used to analyze repeated measures data to compare outcomes in both groups. Average age for cupping therapy group and conventional treatment group were 31.7 (±7.6) and 32.6 (±12.7) years, respectively (P = 0.45). After treatment for 2 weeks; and 1, 3 and 6 months, severity of headache (P = 0.80), frequency of migraine attacks (P = 0.63) and duration of attacks per hours (P = 0.48) were similar in conventional and cupping groups but these symptoms were decreased in each group during the study (P cupping plus serkangabin therapy and conventional treatment in the treatment and prophylaxis of migraine. The alternative therapy may be used in cases of drug intolerance, no medication response, and in primary care.

    The purpose of the study was to evaluate the efficacy of antimicrobial photodynamic therapy (aPDT) used as an adjunct to the endodontic re-treatment in the eradication of microorganisms from previously filled root canals. The study sample consisted of 21 randomly selected patients with root filled and infected root canal system with chronic apical periodontitis on incisors or canines, who have had previously endodontic treatment. Microbiological samples from the root canals were collected after accessing the canal, following the endodontic re-treatment and after the aPDT procedure. During instrumentation, the root canals were irrigated with 2.5% sodium hypochlorite (NaOCl), and the final irrigation protocol included 17% ethylenediaminetetraacetic acid followed by NaOCl. Root canals were filled with a phenothiazinium chloride and irradiated with a diode laser (λ=660 nm, 100 mW) for 1 min. Microbiological samples from the root canals were cultivated on selective plates, and the identification was done by micromorphology, macromorphology and different API strips as well as bacterial counts (colony forming units). Fourteen bacteria species were isolated from the root canals initially, with a mean value of 4.57 species per canal. Although endodontic re-treatment alone produced a significant reduction in the number of bacteria species (pendodontic treatment and aPDT was statistically more effective (proot canals of 11 teeth. The results indicated that the aPDT used as an adjunct to the conventional endodontic therapy achieved a significant further reduction of intracanal microbial load. Copyright © 2014 Elsevier B.V.

    Robot-assisted movement training can help individuals with stroke reduce arm and hand impairment, but robot therapy is typically only about as effective as conventional therapy. Refining the way that robots assist during training may make them more effective than conventional therapy. Here, the authors measured the therapeutic effect of a robot that required individuals with a stroke to achieve virtual tasks in three dimensions against gravity. The robot continuously estimated how much assistance patients needed to perform the tasks and provided slightly less assistance than needed to reduce patient slacking. Individuals with a chronic stroke (n = 26; baseline upper limb Fugl-Meyer score, 23 ± 8) were randomized into two groups and underwent 24 one-hour training sessions over 2 mos. One group received the assist-as-needed robot training and the other received conventional tabletop therapy with the supervision of a physical therapist. Training helped both groups significantly reduce their motor impairment, as measured by the primary outcome measure, the Fugl-Meyer score, but the improvement was small (3.0 ± 4.9 points for robot therapy vs. 0.9 ± 1.7 for conventional therapy). There was a trend for greater reduction for the robot-trained group (P = 0.07). The robot group largely sustained this gain at the 3-mo follow-up. The robot-trained group also experienced significant improvements in Box and Blocks score and hand grip strength, whereas the control group did not, but these improvements were not sustained at follow-up. In addition, the robot-trained group showed a trend toward greater improvement in sensory function, as measured by the Nottingham Sensory Test (P = 0.06). These results suggest that in patients with chronic stroke and moderate-severe deficits, assisting in three-dimensional virtual tasks with an assist-as-needed controller may make robotic training more effective than conventional tabletop training.

    Purpose: To evaluate long-term health effects, costs, and cost-effectiveness of positron emission tomography (PET)-based isotoxic accelerated radiation therapy treatment (PET-ART) compared with conventional fixed-dose CT-based radiation therapy treatment (CRT) in non-small cell lung cancer (NSCLC). Methods and Materials: Our analysis uses a validated decision model, based on data of 200 NSCLC patients with inoperable stage I-IIIB. Clinical outcomes, resource use, costs, and utilities were obtained from the Maastro Clinic and the literature. Primary model outcomes were the difference in life-years (LYs), quality-adjusted life-years (QALYs), costs, and the incremental cost-effectiveness and cost/utility ratio (ICER and ICUR) of PET-ART versus CRT. Model outcomes were obtained from averaging the predictions for 50,000 simulated patients. A probabilistic sensitivity analysis and scenario analyses were carried out. Results: The average incremental costs per patient of PET-ART were €569 (95% confidence interval [CI] €−5327-€6936) for 0.42 incremental LYs (95% CI 0.19-0.61) and 0.33 QALYs gained (95% CI 0.13-0.49). The base-case scenario resulted in an ICER of €1360 per LY gained and an ICUR of €1744 per QALY gained. The probabilistic analysis gave a 36% probability that PET-ART improves health outcomes at reduced costs and a 64% probability that PET-ART is more effective at slightly higher costs. Conclusion: On the basis of the available data, individualized PET-ART for NSCLC seems to be cost-effective compared with CRT.

    Acupuncture has served as a major complementary and alternative therapy that supplements conventional medicine and is the subject of growing public interest. This study was conducted to estimate the usage rate of acupuncture as a supplemental treatment in acute ischaemic stroke patients and to identify factors associated with the choice to use this therapy. Using the registry of stroke patients admitted to an academic medical centre in Korea, the use of acupuncture therapy was recorded and analysed, along with the patients' socio-demographic characteristics, hospital access variables, risk factors for ischaemic stroke and clinical characteristics. The data were analysed using descriptive statistics, chi-square tests and multiple logistic regression analyses. Of 2167 patients, 18% received acupuncture therapy. The choice of acupuncture therapy was significantly associated with stroke severity as well as gender, age, geographical residence and previous history of stroke. After controlling for other significant factors, there was an approximately 3.4-fold greater usage in patients with moderately severe strokes (95% confidence interval (CI)=2.5-4.6) and 4.1-fold greater usage in patients with severe strokes (95% CI=2.7-6.4). The findings provide a better understanding of patients' utilization of acupuncture therapy as a supplement to conventional medical treatments and of factors associated with the utilization of acupuncture in patients with acute ischemic stroke. Strategic implications of acupuncture therapy are suggested for both health-care providers and policy makers. Copyright © 2011 Elsevier Ltd. All rights reserved.

    Low-grade glioma (LGG) is a very common brain tumor in pediatric patients typically associated with a very good prognosis. This prognosis makes it imperative that the risk of long-term treatment-related side effects be kept at an absolute minimum. Proton therapy (PRT) provides a radiation technique that has the potential to further reduce the genesis of radiogenic impairment. We retrospectively assessed 74 patients with LGG who underwent PRT. Conventional three-dimensional photon and PRT plans were generated after contouring structures of neurogenesis, crucial neuronal structures, and areas susceptible to secondary malignancies. Target volume coverage was evaluated using the homogeneity index (HI) and inhomogeneity coefficient (IC). Results were compared using the Wilcoxon-signed rank test, with p < 0.05 being statistically significant. Target volume coverage was comparable for the photon and proton plans. Overall, we could show an essential reduction in maximal, mean, and integral doses in critical neurologic structures, areas of neurogenesis, and structures of neurocognitive function. The study indicated specifically how contralaterally located structures could be spared with PRT. PRT is a highly conformal radiation technique offering superior dosimetric advantages over conventional radiotherapy by allowing significant dose reduction for organs at risk (OAR) that are essential for neurologic function, neurocognition, and quality of life, thus demonstrating the potential of this technique for minimizing long-term sequelae.

    Communication between different health care providers (conventional and complementary) and cancer patients about their use of complementary therapies affects the health and safety of the patients. The aim of this study was to examine the qualitative research literature on the perception of and communication about the risk of complementary therapies between different health care providers and cancer patients. Systematic searches in six medical databases covering literature from 2000 to 2015 were performed. The studies were accessed according to the level of evidence and summarized into different risk situations. Qualitative content analysis was used to analyze the text data, and the codes were defined before and during the data analysis. Twenty-nine papers were included in the primary analysis and five main themes were identified and discussed. The main risk situations identified were 1. Differences in treatment concepts and philosophical values among complementary and conventional health care providers. 2. Adverse effects from complementary products and herbs due to their contamination/toxicity and interactions with conventional cancer treatment. 3. Health care physicians and oncologists find it difficult to recommend many complementary modalities due to the lack of scientific evidence for their effect. 4. Lack of knowledge and information about complementary and conventional cancer treatments among different health care providers. The risk of consuming herbs and products containing high level of toxins is a considerable threat to patient safety (direct risk). At the same time, the lack of scientific evidence of effect for many complementary therapies and differences in treatment philosophy among complementary and conventional health care providers potentially hinder effective communication about these threats with mutual patients (indirect risk). As such, indirect risk may pose an additional risk to patients who want to combine complementary therapies with

    Full Text Available Abstract Background Spontaneous intracerebral hemorrhage (ICH is a devastating form of stroke with the high mortality twofold to sixfold higher than that for ischemic stroke. But the treatment of haematomas within the basal ganglia continues to be a matter of debate among neurologists and neurosurgeons. The purpose of this study is to judge the clinical value of minimally invasive stereotactic puncture therapy (MISPT on acute ICH. Methods A prospective controlled study was undertaken. The clinical trial was in compliance with the WMA Declaration of Helsinki - Ethical Principles for Medical Research Involving Human Subjects. According to the enrollment criterion, there were 168 acute ICH cases analyzed, of which 90 cases were performed by MISPT ( MISPT group, MG and 78 cases by Conventional craniotomy (CC group, CG, by means of compare of Glasgow Coma Scale(GCS score, postoperative complications(PC and rebleeding incidence(RI, moreover, long-term outcome of 1 year postoperation judged by Glasgow Outcome Scale (GOS, Barthel Index (BI, modified Rankin Scale (mRS and case fatality(CF. Results MG patients showed obvious amelioration in GCS score compared with that of CG. The total incidence of PC in MG decreased obviously compared with that of CG. The incidences of rebleeding in MG and CG were 10.0% and 15.4% respectively. There was no obvious difference between CFs of MG and CG. For three parameters representing long-term outcome, the GOS, BI and mRS in MG were ameliorated significantly than that of CG. Conclusion These data suggested that the advantage of MISPT was displayed in minute trauma and safety, and seemed to be feasible and to had a trend towards improved long-term outcome.

    Complement inhibitors have not been thoroughly evaluated in the treatment of acute antibody-mediated rejection (ABMR). We performed a prospective, single-arm pilot study to investigate the potential effects and safety of C1 inhibitor (C1-INH) Berinert added to high-dose intravenous immunoglobulin (IVIG) for the treatment of acute ABMR that is nonresponsive to conventional therapy. Kidney recipients with nonresponsive active ABMR and acute allograft dysfunction were enrolled between April 2013 and July 2014 and received C1-INH and IVIG for 6 months (six patients). The primary end point was the change in eGFR at 6 months after inclusion (M+6). Secondary end points included the changes in histology and DSA characteristics and adverse events as evaluated at M+6. All patients showed an improvement in eGFR between inclusion and M+6: from 38.7 ± 17.9 to 45.2 ± 21.3 mL/min/1.73 m(2) (p = 0.0277). There was no change in histological features, except a decrease in the C4d deposition rate from 5/6 to 1/6 (p = 0.0455). There was a change in DSA C1q status from 6/6 to 1/6 positive (p = 0.0253). One deep venous thrombosis was observed. In a secondary analysis, C1-INH patients were compared with a similar historical control group (21 patients). C1-INH added to IVIG is safe and may improve allograft function in kidney recipients with nonresponsive acute ABMR. © Copyright 2015 The American Society of Transplantation and the American Society of Transplant Surgeons.
