Active clinical trials for "Joint Diseases"

The primary outcome of this study is to determine the true incidence of smokers among patients undergoing joint replacement and secondly, what percent are able to quit smoking before surgery under a structured cessation program with carbon monoxide breath testing. The investigators hypothesize that self-reported smoking status is underreported and that routine carbon monoxide breath testing will improve abstinence rates at the time of surgery.

It is planned to examine the relationship between quality of life in patients with temporomandibular joint dysfunction and the patient's individual, physical and psychosocial characteristics.

The purpose of this study; to compare individuals with and without chronic constipation in terms of sacroiliac joint dysfunction and to examine the relationship between chronic constipation and sacroiliac joint.

Patients suffering from chronic degenerating diseases are often treated by a plethora of NSAIDs, DMARDs, Biologicals, as well as combinations of these therapeutics. However, many patients are refractory to this treatment and suffer from chronic pain over years, leading to a worsening of the quality of live. The mobilization of these patients is one main goal in the therapy of these chronic and inflammatory diseases. Low dose radiation therapy (LDRT) is applied since more than one century for the local treatment of chronic degenerating joint diseases. The success of the treatment was described by many retrospective as well as pattern of care studies, respectively. Local (only at the painful joint) low dose irradiation of the chronic patients results in most patients in a significantly reduced pain, not only direct after the therapy, but also lasting for more than 12 month in many cases. The patients experience enhanced mobility and increased quality of life. The molecular and cellular processes leading to the pain reduction are just fragmentarily analyzed. Our group revealed that macrophages are key players in radiation-induced immune modulation. Inflammatory macrophages exposed to low doses of radiation showed a reduced inflammatory capacity and attenuated an inflammatory microenvironment. Besides macrophages further immune cells are most likely involved in reduction of inflammation following LD-RT, as in vitro already shown for neutrophils. The IMMO-LDRT01 study aims for the first time to analyze in detail the immune status of patients suffering from inflammatory, chronic joint diseases before, during and after LD-RT in a longitudinal manner. The multi-color flow cytometry-based assay will allow determining over 30 immune cell subsets and additionally their activation status. Further, biodosimetry will be performed with the whole-blood samples to get hints about dose that the immune cells are exposed to. This will be performed with national and international co-operation partners. The IMMO-LDRT01 study is a prospective and observational study not influencing the standard therapeutic scheme and will provide hints how the LDRT affects besides local cells in the irradiated area also the systemic inflammatory response.

Hemophilia is a genetic condition characterized by marked phenotypic heterogeneity. Bleeding into a joint is the single most important risk factor for the development of hemophilic arthropathy (HA). It is thought that clinical and imaging manifestations of HA are at least partially attributable to genetic polymorphisms unrelated to the hemophilia genotype. Identifying and characterizing biologic factors that could explain differences in susceptibility to joint degeneration of patients with hemophilia would help stratify patients according to the risk of degeneration of their joints and develop personalized therapeutic and prophylactic strategies. This study is conducted in China.

Sometime osseous reconstruction needs allogeneic bone, in this study we use Ostéopure™ from Ostéobanque d'Auvergne, which is a osseous matrix. However Ostéopure™ integration lasts a long time. To optimize this integration we purpose to associate mesenchymal progenitors cells from autologous bone marrow.

According to our previous research and clinical observation results, the motor function of the oral, maxillofacial and cervical body is closely related to the occlusal contact. Not only that, the occlusal contact also affects the psychological activities related to movement. There are many technical means to evaluate the occlusion clinically. However, the occlusion is a complex motor organ with more than 3 dimensional (including age factors) morphological characteristics, which makes the occlusion have obvious individualized characteristics. It is of great significance to objectively evaluate oral health to accurately extract occlusal contact features, analyze the relationship between occlusion and the motor function of oral, maxillofacial, neck and body as well as the corresponding psychological characteristics, and establish an evaluation method of occlusal function for evaluating motor function and psychological characteristics.

To develop a new type of knee joint pressure detection device and demonstrate its feasibility To analyze individual differences of knee ligament tension using the new device and explore the influencing factors of ligament tension To explore the correlation between knee ligament tension and postoperative knee function

Chronic peripherial arthritides are common diseases with soaring public health consequences. Our goal is to assess the role of photon-counting detector computed tomography in the diagnostics of peripherial arthropathies.

Hemophilia is associated with osteoporosis and increased prevalence of low bone mineral density (BMD). Many clinical risk factors have been reported, such as hemophilic arthropathy, reduced physical activity, decreased sun exposure, hepatitis C virus infections, vitamin D deficiency, and low body mass index (BMI). There is no data on the prevalence of vitamin D deficiency and low BMD in hemophilia patients in Taiwan or Asia. To the best of our knowledge, no previous studies have reported the prevalence of sarcopenia and correlation with osteoporosis in hemophilia adult patients. The purpose of this study will evaluate the prevalence of vitamin D deficiency, low BMD, sarcopenia and body composition in a cohort of patients with hemophilia in Taiwan.
