There are about 173942 clinical studies being (or have been) conducted in United States. 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 whether suppressing acid production by administration of daily proton pump inhibitors in the early post-operative period will reduce the gastrojejunal anastomosis stricture rate in patients undergoing laparoscopic gastric bypass surgery for morbid obesity.
Lipoatrophy is a condition that affects certain individuals, most commonly those who are infected with the HIV virus. Lipoatrophy however can also affect individuals who suffer from recurrent systemic infections, those who have a weakened immune system, or certain patients who suffer from cancer or receive chemotherapeutics. In contrast, lipoatrophy can sometimes be present in individuals who are perfectly healthy but have genetically predisposing factors that can contribute to facial emaciation or lipoatrophy. The function of injectable fillers for the treatment of dermal contour deformities is to smooth dermal depressions formed by the loss of volume. These often elastic contour fillers (also known as soft tissue augmentation devices) can correct hollowness around the eyes, add fullness to thin lips, balance a disproportionate face or correct topographical anomalies. This study aims to: - Objectively measure the improvement of contour-deformities after Sculptra™ injection from baseline to study closure by utilizing the Primos™ photographic/topographical measuring system. - Evaluate the efficacy, longevity and duration of volume-correction in subjects which are both HIV positive and HIV negative. - Assess the safety of Scupltra™ dermal filler when used to correct volume deformities caused by lipoatrophy in subjects that are HIV negative.
We are investigating whether, after surgical cure of primary hyperparathyroidism, alendronate provides even greater beneficial skeletal effects than parathyroidectomy alone. Primary Hyperparathyroidism (PHPT) is a disorder that can be associated with bone loss. After successful surgery for PHPT bone density improves without any treatment. However, it is possible that bone density might improve to an even greater extent if Fosamax is used after the surgical cure. Fosamax is approved by the FDA for the prevention and treatment of osteoporosis, and the goal of this project is to determine whether after successful surgical cure of PHPT, Fosamax is even better for the skeleton than just parathyroid surgery alone.
Turbinates are large structures in the nasal airway that help the nose to clean and humidify the air we breathe. Inferior turbinates can swell up and block the breathing passage, making it hard to breath. To address this, turbinate size must be reduced. This study looks at two common procedures for turbinate reduction: 1. Radiofrequency Ablation (RFA) involves inserting a special needle into the inferior (lower) turbinate that releases thermal energy, which significantly reduces its size. This can be done under local anesthesia at the doctor's office. 2. Partial Resection of Inferior Turbinate (PRIT) involves surgically removing a piece off the turbinate, which also reduces its size. While both procedures improve nasal obstruction, no study has directly compared which is more effective. Eighty patients being treated for septal deformity and turbinate hypertrophy will be randomly chosen for either PRIT or RFA treatment. They will fill out a simple, five question survey that measures how they view their nasal blockage 4 times in one year. We believe that since PRIT permanently removes a part of the turbinate, PRIT patients will report more improvement than RFA patients one year later. We believe that complications (measured by the doctor) will be the same for both treatments.
Early physical therapy after knee surgery is very painful on top of pain from surgery. Pain following surgery can limit recovery. One way to treat pain is by giving intravenous (IV) pain medication with morphine. Another method is to use a "nerve block" which involves placing a thin catheter (tube) into the lower back near the nerves that sense pain in the knee and give a local anesthetic to numb the nerves. Sometimes both methods are used together. This research is being done to determine whether nerve blocks with a local anesthetic improve knee recovery in addition to providing pain relief as compared to IV pain medicine alone
The purpose of this research project is to determine the effects of oral tetracycline such as Minocycline (Minocin) on tear film composition and tear lipid (meibomian gland secretions) characteristics in patients with chronic Blepharitis and associated dry eyes.
The purpose of this study is to see if treating a donor site wound with the ACell dressing is as good as or better than the dressings we currently treat harvested donor sites with. This will be tested on consenting burn patients who require excision and grafting surgery for their burn wounds. Hypothesis: The mean healing time for wounds treated with the ACell dressing will be less than the mean healing time for wounds treated with the Standard of Care dressing.
The purpose of this study is to see if intravenous Vitamin C will decrease the amount of IV fluids needed following burn injury in the first 48 hours.
The purpose of this study is to investigate the effects of transcranial magnetic stimulation on pain perception.
The purpose of this study is to determine what effect teriparatide will have on vascular (blood vessel) compliance and osteoprotegerin (bone fluid)and RANKL levels (bone cells).
