Background: \- The immune system is made up of special cells, tissues, and organs that fight infections. Problems with this system may lead to frequent, severe, or unusual fungal infections. These infections are often difficult to treat. Researchers want to collect blood and tis…

Alloimmunization to blood products in transfused patients is a recognized management challenge in the clinical setting. In particular the ethnic and racial specificity of RBC antigens and the limited availability of matched healthy volunteer blood donors have intensified the dile…

The purpose of this study is to determine the effects (good or bad) of pulsed dye laser treatment in burn scar height, texture, redness and pliability in acute burn injury.

While the literature tends to support the use of laser therapy in the management of burn scars, there is a definite lack of appropriately powered, randomized controlled trials. Laser therapy can be quite expensive when compared to other treatment modalities for burn scars, and wh…

The objective of this study is to determine if Gastric Electrical Stimulation may influence vagal outflow via vagal afferent fibers that terminate in the Central Nervous System.

The VITamin D and OmegaA-3 TriaL (VITAL; NCT01169259) is a randomized clinical trial in 20,000 U.S. men and women studying whether taking daily dietary supplements of vitamin D3 (2000 IU) or omega-3 fatty acids (Omacor® fish oil, 1 gram) reduces the risk of developing cancer, hea…

In order to better understand early onset obesity and to identify patients in interested in future research studies, including clinical trials, we aim to develop a registry for patients with early onset obesity.

This registry study is intended to establish a large prospective longitudinal clinical cohort of lymphoma patients in Malawi, as such data is currently lacking from sub-Saharan Africa. The investigators will perform core biopsies on at least 800 consecutively enrolled patients wi…

The primary objective of this study is to compare the efficacy of unilateral and bilateral neuromodulation tests at 1 month.

A clinical trial to evaluate the long-term efficacy and safety of Chondron (Autologous cultured Chondrocyte) administered through arthroscopy from the drug's 48 weeks efficacy and safety evaluation with 96 weeks follow-up in patients with knee cartilage defects.

The goal of this clinical trial is to evaluate the impact of supervised training program on body composition, muscular strenght, insulino-resistance profile, heart rate variability and on heart structure and function between 3 to 6 months after mixed bariatric surgery or restrict…

This Phase I/Ib trial is studying the absorption and metabolism of phytochemicals found in black raspberries in men undergoing surgery for prostate cancer. This knowledge will help us design future chemoprevention studies and assist in making future dietary recommendations for me…

After curative surgical resection, detection of metastatic lymph node remains the main prognostic validated criteria on which is based the decision of adjuvant therapy. To date, none of the molecular alterations, identified as potentially predictive factor, are used in routine fo…

Objective: Epidural analgesia is the gold standard for post-thoracotomy pain relief but is contraindicated in certain patients. An alternative is continuous wound catheter analgesia. We will investigate whether ropivacaine, administered through a wound catheter placed by the surg…

The principal objective is to assess the general health status and the sexual health status of women with Rokitansky syndrome having received a surgical or non surgical treatment. The secondary purpose is to assess the anatomical aspect and the quality of sexual life. To search …

Background: \- The ABCA4 gene contains a blueprint for the ABCA4 protein. When this protein is absent or faulty (such as in Stargardt s disease), waste material from dead cells collects in the eye. The waste material may cause other cells in the eye to die. This can lead to the …

Background: \- Gum disease is a condition in which the tissue around the tooth root becomes swollen and infected. This condition can cause tooth loss if it is not treated. Who gets gum disease and how bad it will be depends on (1) the different bacteria in the mouth and (2) how …

The purpose of this study is to determine whether a standardized education and exercise program proposed before a total knee replacement for knee osteoarthritis is effective in functional recovery after surgery.
