Effects of Non Contact Low Frequency Ultrasound in Healing Venous Leg Ulcers
Venous InsufficiencyVenous Reflux1 moreThis trial is a prospective, randomized, controlled, multi-center study of subjects presenting with chronic lower extremity venous ulcers. The study will evaluate the safety and effectiveness of MIST Therapy® plus standard of care (MIST+SOC) compared to Standard of Care (SOC) alone in the treatment of lower extremity venous ulcers.
Topical Sodium Nitrite for Chronic Leg Ulcers in Adult Patients With Blood Disorders
Sickle Cell AnemiaSickle Cell Disease1 moreBackground: - Chronic leg ulcers are a complication of many blood disorders such as sickle cell disease, thalassemia, and other red blood cell disorders. In these disorders, red blood cells break down earlier than normal, which researchers suspect may cause or contribute to the development of leg ulcers; however, the exact cause is unknown, and current therapies are not very effective. Researchers are interested in determining if a research cream made with sodium nitrite, a substance that is known to increase blood flow by dilating blood vessels, may speed up the healing of skin ulcers. Objectives: - To evaluate the safety and effectiveness of topical sodium nitrite cream as a treatment for chronic leg ulcers in individuals with sickle cell disease or other red blood cell disorders. Eligibility: - Individuals at least 18 years of age who have sickle cell disease or another red cell disorder and have had a leg ulcer for more than 4 weeks. Design: Participants will be screened with a physical examination, medical history, blood tests, and an examination of the ulcer, including x-ray of the leg(s) with the ulcer and swabs from the wound. Participants will be scheduled for a 5-day inpatient stay at the Clinical Center, with the following procedures: Days 1 and 2: Participants will have blood draws, a wound assessment, ultrasound of the affected leg, imaging studies (magnetic resonance imaging and infrared photography), thermo-patch application to monitor temperature changes, measurements of blood flow in the skin, and questionnaires about pain and quality of life. An optional skin biopsy may also be conducted with samples taken near the skin ulcer Day 3: Participants will have one ulcer treated with the topical cream. Frequent blood draws will be conducted before application and then regularly for up to 6 hours after application of the cream. Thirty minutes after the research cream is applied, participants will have imaging studies of the treated leg and measurements of pain levels and blood flow. Day 4: Participants will have a blood draw and temperature recordings taken. Day 5: Participants will have the research cream applied and the same imaging studies as before, and will be discharged for care at home. For the following 3 weeks, participants will come to the clinical center twice a week to have the research cream applied to the leg ulcer and tests performed by the study researchers. For the fourth and final week, participants will return for additional cream treatment sessions, imaging studies, blood draws, and other tests as directed by the study researchers. Study participation will end in the following week (week 5). Subjects will come for a final visit one month after the end of the study.

Evaluation of Bilayered Cellular Matrix (OrCel) for the Treatment of Venous Ulcers
Venous Leg UlcerVenous Stasis UlcerThis study was designed to evaluate the clinical benefits and safety of OrCel in the treatment of venous ulcers. OrCel and standard care were compared to standard care alone. Standard care consisted of currently accepted compression therapy. Patients were treated for 12 weeks. Patients with healed ulcers were followed for an additional 12 weeks to assess durability of the healed wound.
