There are about 28871 clinical studies being (or have been) conducted in Canada. The country of the clinical trial is determined by the location of where the clinical research is being studied. Most studies are often held in multiple locations & countries.
The primary goal of this trial is to compare prospectively stent opening of Supera (IDEV Technologies) versus a reference stent (LifeStent, Bard Medical) using C-arm CT. A secondary goal is to correlate stent opening with stent patency as documented by Doppler ultrasound at one year post implantation.
The results of studies conducted until now does not determine what the best way to treat infertility in the first line with patients with Polycystic ovary syndrome (PCOS). This study objective is to determine the best treatment for such patients. The long-term consequence health of women with PCOS are multiple. The woman with PCOS has a risk of developing metabolic diseases, heart diseases, diabetes Type II or anovulatory infertility. The insulin resistance plays an important role in all this medical condition. Clomiphene Citrate (CC) remains the first line treatment to induce ovulation in women with PCOS and anovulatory infertility.
Objective: The aim of this study is to investigate whether Crohn's Disease patients with peri-anal fistulas will suffer from sexual dysfunction in an attempt to help us identify Crohn's Disease patients that would benefit from sexual health interventions. Hypothesis: Crohn's patients with active perianal fistulas will have decreased sexual drive, performance, and satisfaction than those with Crohn's Disease in remission.
This study will examine how successfully nerves are blocked or frozen for hand surgery. Traditionally, the nerves are frozen at the base of the neck, just above the clavicle or collarbone (the supraclavicular block). This is mostly successful by itself, and provides anesthesia of the entire arm. Occasionally, an additional nerve block is required further down the arm, as the supraclavicular block may have missed a segment, or it is taking too long to come on. In this study the investigators will compare the traditional technique, with a similar but lower volume supraclavicular block plus an immediate low volume block of one nerve further down the arm (the ulnar or median nerve block, depending on which digits are being operated on). The investigators will compare success rates, speed of onset, procedural comfort and length of time of weakness and numbness, plus any adverse events.
Left main stenosis use to be treated by bypass but with the improvement of angioplasty techniques, an increasing number of patients are submit to left main coronary angioplasty. Consequences of left main intra stent stenosis can be disastrous yet, for the moment, no precise recommendation concerning the follow up of these patients exist. The investigators ought to determine if stress echocardiography can predict left main intra stent stenosis as well (non inferiorly)as control angiography that use to be done.
The purpose of this study is to evaluate leg health for one additional year in patients with symptomatic proximal deep venous thrombosis who did not already develop Post-Thrombotic Syndrome (PTS) during the 2 years of follow up in the SOX Trial.
The investigators will test whether hypotonic (diluted) remodulin solution causes less pain than the eutonic (undiluted) solution supplied by the manufacturer.
The hypothesis of this study is that canine fossa trephination (CFT) improves surgical outcomes for patients with a severely diseased maxillary sinus.
Participants will be randomized to undergo a High Tibial Osteotomy (HTO) with or without a knee scope. Patients will be tested in the Gait Lab, will fill out quality-of-life questionnaires, and have a clinical evaluation done preoperative and at each follow-up visit.
The aim of our study is to determine the time to resolution of individual acne lesions using a popular handheld heat based device in comparison to no treatment and to standard topical therapy with benzoyl peroxide in order to determine its effectiveness in the spot treatment of acne vulgaris. Patient satisfaction and potential side effects will be examined as well.
