14 Clinical Trials for Various Conditions
Multi-center, prospective, open-label, single arm study. The study aims to evaluate the safety and efficacy of Laser Assisted Liposuction procedure performed with the LipoLife system. The study will include twenty (20) eligible subjects, that are willing to undergo abdominal or outer thighs laser-assisted liposuction. Five to twenty (5-20) subjects out of this study group should also be eligible for facial fat grafting. Follow up visits to evaluate study endpoints will take place at 1, 3 and 6 months after the surgery.

The purpose of this study is to evaluate the safety and effectiveness of a study medication that contains a combination of a pain medication, sufentanil, and a sedative, triazolam. This drug is being designed to provide mild sedation as well as reduce anxiety and pain before and during a procedure (in this case elective abdominal liposuction).
Sedation, Anxiety, Pain
The purpose of this study is to determine if a less invasive procedure such as liposuction can be used to effectively reduce arm lymphedema (swelling of the arm) resulting from breast cancer treatment. The standard surgery involves the removal of large portions of skin and tissue leaving a large scar. This less invasive procedure (liposuction) uses 3 to 4 tiny puncture sites and a vacuum tube leaving minimal scars.

This study is for women who have already decided to undergo liposuction at Georgetown University Medical Center in Washington, D.C. To take part in this study, a woman must first meet with the plastic surgeons there, and be accepted by them to have liposuction. This study will investigate whether large volume liposuction improves risk factors for heart disease in overweight women with type 2 (adult onset) diabetes, impaired glucose tolerance, or elevated blood insulin levels. Large volume liposuction is the surgical removal of at least 10 pounds (4.5 kg) of body fat, usually from the abdomen, hips or chest. Risk factors for heart disease include high blood pressure and elevated levels of blood lipids (cholesterol and triglycerides), blood glucose (sugar), and blood insulin. Subjects who participate in all parts of this study will receive a total of $930.00. Overweight women 18 years or older with high blood insulin levels, impaired glucose tolerance, or type 2 diabetes, who are planning to have large volume liposuction performed at Georgetown University Medical Center in Washington, D.C., may be eligible for this study. For a subject to be accepted into this study, she must first meet with the plastic surgeons at Georgetown University Medical Center, and they have to agree to perform large volume liposuction. The decision that someone is suitable for liposuction is not under the control of the NIH or of any NIH investigator. Those enrolled will undergo the following procedures at four separate times - before undergoing liposuction, 4 weeks after surgery, 4 months after surgery and 1 year after surgery: * Body measurements - taken with calipers to measure several skinfold thicknesses (the width of a fat fold) and with a tape measure to measure the circumference of parts of the body. * Urine sample and 6-hour urine collection - to test for pregnancy and to evaluate kidney function. * Glucose tolerance test - measures insulin sensitivity and how the body uses sugar, how well insulin works, and insulin sensitivity. The procedure involves placement of two catheters (thin, flexible tubes) through a needle into a vein in each arm. Sugar water is infused into one catheter and 20 minutes into the test a small amount of insulin is injected. Blood samples are drawn from the other catheter at frequent intervals for a total of 5 hours. * Electrocardiogram (ECG) and echocardiography - measure the heart's electrical activity and function. * Abdominal computerized tomography (CT) scan - produces images for measuring body fat in the abdomen. (not done at the 4-week visit). Takes about half an hour to complete. * DXA X-ray - measures body fat, muscle and bone mineral content. Takes about half an hour to complete. * Bod Pod - capsule-like device used to determine the proportion of body weight composed of fat and non-fat tissue. Takes less than 10 minutes * Bioelectric impedance analysis device - measures the proportions of body fat based on electrical conduction of a small electric current. Takes 2-3 minutes. * 24-hour blood pressure monitoring - a device attached to a blood pressure cuff strapped to the arm measures blood pressure every 15 to 30 minutes continuously for 24 hours. * Vascular reactivity tests - a blood pressure cuff is inflated for about 4 minutes before deflating, providing information on the function of the small blood vessels in the skin, as well as an idea of the function level of small blood vessels elsewhere in the body. Takes half an hour. * Blood samples - collected to evaluate kidney and liver function and to measure body lipids, such as cholesterol, minerals, and other substances.

This prospective study aims to evaluate the safety and effectiveness of AVELI for reducing cellulite and fibrotic tissue in patients undergoing High-Definition Liposculpture, exploring if AVELI improves the aesthetic outcomes, and reduced the clinically evident cellulite and/or fibrosis. The main questions this study seeks to answer are: * Does AVELI safely reduce cellulite and fibrotic tissue without causing serious adverse events? * How effective is AVELI in improving patient-reported outcomes and aesthetic appearance? Through this study, the study team aims to evaluate the safety and effectiveness of AVELI. The study procedures include: * Baseline data collection of sociodemographic variables. Data collection of surgical variables, adverse events, and satisfaction scores. * All patients will undergo the standardized High-Definition Liposculpture technique, with AVELI applied to all identified cellulite and/or fibrosis release. * Photographic and 3D imaging preoperatively and at follow-ups (1, 3, 6, and 9 months).

The purpose of this study is to compare the effectiveness of two methods in the treatment of excessive underarm sweating (axillary hyperhidrosis): suction-curettage and Botox injections. Suction-curettage is a method in which the doctor will insert a suction tool into two small incisions in order to suction out the sweat-producing glands. It is similar to liposuction, but instead of suctioning out fat, the doctor suctions out the layer of the deep skin where the sweat glands are located. This method has been shown in some studies to effectively reduce underarm sweating for months at a time. Botox is a Food and Drug Administration (FDA) approved drug that in small doses, paralyses muscles. It is most commonly and famously used in the treatment of facial wrinkles. However, it has also been approved to treat excessive sweating. When injected in areas that sweat excessively, sweating can be significantly reduced in that area for months at a time. This study is a pilot study designed to determine feasibility of these procedures.
Axillary Hyperhidrosis
The typical female pattern of accumulating fat in the hips and thighs has long been thought to confer less risk for disease than the typical male abdominal fat pattern. However, leg fat may not simply be benign with respect to disease risk, but may in fact protect against cardiovascular disease risk. Although the mechanism for this is unknown, the investigators hypothesize that removing a portion of this important fat depot (via liposuction) could increase disease risk. Such unfavorable results may or may not be transient depending on an individual's ability to defend their fat mass. Because sex hormones appear to play a role in regional fat accumulation, the investigators hypothesize that estrogen-deficient postmenopausal women may have an augmented abdominal fat accumulation and an attenuated hip and thigh re-accumulation compared to premenopausal women following lipectomy and compared to non-surgical controls. As a result, the increased abdominal fat accumulation may worsen disease risk in postmenopausal women. Menopause-related differences in fat storage at baseline are also expected to determine the degree to which lipectomy alters disease risk and the propensity for AT re-accumulation.

This research study is to evaluate the natural history of fat transplanted from a person's body to their breasts. We are seeking a natural, safe, and effective alternative to breast implants. Patients will undergo liposuction of their body followed by infiltration of this harvested fat around their breasts. The study protocol will involve preoperative and postoperative photographs, mammograms, and MRI to look for changes in the breast shape and size, as well as any internal changes in the breast tissue.
