Multimodal Imaging of Subchondral Bone in Knee Osteoarthritis : Predictive Model
Knee OsteoarthritisJoint Disease2 morePredictive factors of osteoarthritis progression are not yet well understood. However, a growing role attaches importance to the subchondral bone. The aim of the present project is to determine predictive factors of progression of osteoarthritis at the knee by a multimodal characterization of subchondral bone by Medical Resonnance Imaging, direct high resolution digitization radiographs and bone texture analysis. At the end of the project, an innovative imaging device, combining semi-automatic softwares for texture analysis, control detection and image registration would be supplied. This will enable on the one hand a more accurate and reproducible way to measure the joint space width of the affected compartment and on the other hand, an assistance to better detect patients at risk of progression of their knee osteoarthritis. Identifying These "progressors" patients might permit their selection in clinical trials at baseline adapted to their severe disease, using for example biologic treatments targeting knee osteoarthritis. The main objective of this study is to analyze the predictive capacities of bone texture parameters measured on the high-resolution radiography of the knee on the structural evolution of the knee osteoarthritis at 3 years.
Trapeziometacarpal Prosthesis vs. Resection-Interposition Arthroplasty
Arthropathy of HandRhizarthrosis is a frequently occurring pathology leading to severe limitations in daily life due to pain and loss of function. Good clinical results have been reported for some carpometacarpal (CMC) joint prosthesis designs, but high failure rates due to loosening and dislocation must be considered. The study aim was to investigate a new, double mobility CMC-prosthesis design with special focus on (1) the functional outcome and (2) patient quality of life (QOL)

The Relationship Between the Parameters Affecting the Functionality of the Pelvic Floor and the...
Pelvic Floor DisordersTemporomandibular Joint DisordersThe aim of our study is to examine the relationship between the parameters affecting the pelvic floor and temporomandibular joint (TMJ) functionality and to emphasize the necessity of investigating combined and coordinated exercise approaches in the treatment of dysfunctions that may occur in both specific regions. Our study, which is planned as an epidemiological research, will include 59 women between the ages of 20-50, who applied to the Istanbul Research and Training Hospital, Gynecology and Obstetrics Polyclinic, and volunteered to participate in the study. Assessments include pelvic floor dysfunction, pelvic floor muscle activation, sacroiliac joint mobility, pelvis position, and pain for pelvic floor functionality; temporomandibular joint dysfunction, masseter muscle activation, temporomandibular joint range of motion, position of the mandible and pain for temporomandibular joint funstionlaity; strength of the muscles located on the deep anterior line and thought to be related, flexibility, myofascial trigger points and depression level for mediating factors affecting functionality. After the data are completed, the Kolmogorov-Smirnov test will be applied to determine whether the data fit the normal distribution before starting the statistical analysis. Pearson Correlation test will be applied between dependent variables, independent variables and mediating factors in case the data show normal distribution, and Spearman Correlation test will be applied if it does not show normal distribution. Significance value will be determined as p<0.05, correlation coefficient between variables r: 0-0.46 (weak); r: 0.5-0.74 (medium); r: will be interpreted as 0.75-1.0 (strong).
Steroid Injection for Sickle Cell Arthropathy Pain Therapy
Sickle Cell DiseaseSickle Cell AbnormalitySickle cell disease (SCD) is associated with arthropathy. Arthropathy may require periarticular corticosteroid injection therapy. This observational study examines efficacy, and safety of steroid injections in SCD patients. Data collection includes patient's gender, age, race, smoking history, alcohol intake, analgesic use, pain score, sleep quality, limb joint injections, post-injection analgesia, and post-injection complication. Pain is measured using numeric pain scale. Sleep quality is measured using Likert scale.
Magnetic Ressonance Imaging of Temporomandibular Joint
Temporomandibular Joint DysfunctionBackground: Among the instrumental devices that have been proposed over the years to integrate the clinical evaluation of temporomandibular joint disorders (TMD), imaging techniques are the most studied, showing that magnetic resonance imaging (MRI) is the technique most need to describe the anatomy of the TMJ and to evaluate the correlation of imaging findings with the clinical diagnosis . Despite the amount available studies on the use of MRI for evaluation of TMJ disorders and treatments, there is a lack of studies that evaluate the imaging findings after physical therapy. Purpose: To evaluate the influence of nonspecific mandibular mobilization about the positioning of the articular disc by MRI in individuals with TMD diagnosis of anterior disc displacement with and without reduction according to the Research Diagnostic Criteria for Temporomandibular Disorders (RDC/TMD). Analyze the behavior of pain through the numerical scale of pain assessment (END) at baseline and after each treatment session, the quality of life of individuals with TMD at baseline, immediately, three and six months after the treatment sessions by the World Health Organization Quality of Life Assessment (WHOQOL - BREF), and The Patient's Specific Functional Scale (PSFS) at baseline and after treatment. The treatment will be performed three times a week during four weeks. Metodology: This is a randomized, placebo controlled, blind study designed to assess the effects of techniques nonspecific mandibular mobilization x placebo. Individuals will be randomized and divided into two groups: Group A (intervention) and Group B (placebo). Statistic analysis: The positioning of the articular disc, extracted through the use of MRI, will be considered the primary outcome and, as a secondary outcome will be assessed the quality of life, pain and function after treatment. The adherence of the data to a Gaussian curve will be verified by the Shapiro-Wilk and the data are expressed as mean values and standard deviation. Two-way repeated measures analysis of variance with Bonferroni post hoc test will be used for inter-and intra-group comparisons. The significance level is adjusted p ≤ 0.05.

English speaking American Society of Anesthesiologists (ASA) 1-3 patients ages 18-80 receiving prolonged interscalene nerve block will be randomized into 3 groups: first group receiving a perineural catheter infusing 0.2% ropivacaine; the second group receiving a single shot injection of 10mL liposomal bupivacaine (Exparel; n=20) plus 5 mL 0.5% bupivacaine and the third receiving 20mL liposomal bupivacaine plus 5mL bupivacaine (to be determined by the attending anesthesiologist).Primary outcome will be incidence of hemidiaphragmatic paralysis postoperative day 1 as measured by point of care (POCUS) ultrasound.
Alloplastic Total Temporomandibular Joint (TMJ) Replacement Registry
Temporomandibular Joint DisordersProspective data will be collected in approximately 200 patients treated with an TMJ replacement. Patients will be followed up according to the standard (routine) for up to 5 years after the treatment. Data collection will include underlying disease, treatment details, functional and patient reported outcomes (PRO)s and anticipated or procedure-related adverse events (i.e. complications). This registry is designed to be able to assess the number of patients who refuse alloplastic total TMJ replacement. Therefore, the participating sites are asked to register all cases of refused TMJ replacements too.
