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 purpose of this study is to determine if a new antimicrobial gauze dressing is better than the current method of dressing open wounds with plain sterile gauze. It is hoped that the antimicrobial gauze will reduce the number of germs in the open wound and even improve the rate of healing.
The therapy under investigation involves an implanted Medtronic neurostimulation system to relieve symptoms of angina pectoris pain. Electrical impulses are applied to targeted areas of the spinal cord through an implanted lead (a flexible insulated wire) that is powered by an implanted battery.
Patients with upper ureteral or renal stones will be randomized to undergoing ureteroscopy with or without a ureteral access sheath. The sheath is designed to facilitate ureteroscope insertion and re-insertion, thus allowing fragments to be basketed out. Stone free rates at 3 months will be determined between the two groups. The investigators hypothesize that the use of the ureteral access sheath with ureteroscopy will result in improved stone free rates at 3 months compared to ureteroscopy without use of a sheath.
The purpose of this study is to evaluate the safety and efficacy of the CCR5 antagonist GW873140 or placebo in combination with an optimized background regimen in treatment-experienced HIV-infected subjects with R5-tropic virus
The objective of the study is to evaluate the acceptance and effect of type- specific HSV serologic testing of pregnant women on sexual behavior at the end of pregnancy.
Hypothesis Nevirapine resistance developed in women and infants in the HIVNET 006 and 012 cohorts as a consequence of use of an agent with a long t½ as monotherapy in individuals with high viral loads. Objective 1 To demonstrate that Nevirapine resistance does not develop in HIV infected patients when used as part of triple antiretroviral combination therapy between the initiation of treatment and suppression of HIV RNA to <1000 copies/ml. Objective 2 To demonstrate that resistance to nevirapine does not develop when patients with suppressed HIV RNA discontinue combination antiretroviral therapy which contains nevirapine.
Comparison of humidification devices during non invasive ventilation, in acute respiratory failure. The hypothesis was, due to dead space, lower humidification, a reduced efficiency of the technique (NIV) when HME are used in comparison with HH.
An estimated 20 - 45 % of women treated with breast conserving treatment experience chronic pain in the treated breast. The aetiology of this is poorly understood. Some of these women have signs of chronic radiation mastitis. There is no accepted treatment for this condition. The combination of pentoxifylline and vitamin E has been shown to be effective in reversing radiation fibrosis in this region. Many of these patients have had a benefit in pain response in a time period of a few benefits. This study is a phase II study of these drugs for a 6 month trial period to assess the effect on chronic breast pain in breast cancer patients who are 3 months to 3 years post radiation treatment.
This study is conducting a comparison of chest x-ray (CXR) and minimum dose thoracic CT (MnDCT) in the detection of lung nodules (metastases) in patients with head and neck carcinoma.
Patients with radiation induced injuries experience significant pain and negative effects on quality of life. Currently, no standard therapy for these patients exists, with some patients treated symptomatically, and others treated with hyperbaric oxygen or pentoxifylline/Vitamin E. This study will examine prospectively the safety and efficacy of using a regimen of pentoxifylline and vitamin E in patients with late radiation induced injuries.
