Active clinical trials for "Skin Ulcer"

Skin ulcer is a common disease with complicated etiopathogenes, which makes it hard to be cured. It has been reported that photodynamic therapy (PDT) can be used to treat skin ulcers which were caused by different diseases. However, PDT is an expensive treatment and patients always experience obvious pain during or after the treatment, which hinders the application of PDT in skin ulcer. Our previous study found that PDT using a low concentration of 5-Aminolevulinic acid (ALA) could promote the healing of skin ulcer without obvious adverse reactions, which suggests us that low concentration ALA-PDT might be an efficient and cost effective treatment in skin ulcer. To further investigate the use of low concentration ALA-PDT in skin ulcer, we plan to recruit patients with skin ulcers caused by different diseases, and divide these patients into different groups according to their causes of disease, and then treat them using low concentration ALA-PDT to observe the healing process of skin ulcer. This study could further optimize and promote the use of low concentration ALA-PDT in skin ulcer.

Management of chronic diabetic foot skin ulcers require multidisciplinary approaches including diabetic control, wound care, antibiotic, shoe wear off-loading, and surgery in selected cases. The results are inconsistent and irregular, and most studies reported unsatisfactory results. Many adjunctive therapies are implemented in the care of chronic diabetic foot ulcers including hyperbaric oxygen therapy (HBO), ultrasound, recombinant human platelet-derived growth factor-BB (rPDGF-BB), vacuum assisted wound closure (VAWC) and acellular matrix. HBO is the most commonly utilized at the investigators institution. Mixed results of HBO in chronic diabetic foot ulcers are reported. Several studies reported that the beneficial effects of HBO, but none showed universal success. Therefore, the development of a new effective method of treatment for chronic diabetic ulcers is extremely valuable. Extracorporeal shockwave therapy (ESWT) acts as mechanotransduction that produces the therapeutic benefits through complex biological pathways including neovascularization and tissue regeneration. ESWT also showed bacteriostatic effects in experiments. Some studies reported the effectiveness of ESWT in acute and chronic soft tissue wounds. Others reported effectiveness of ESWT in chronic ulcers with 50% completely healed with 6 sessions of treatment. With this background, it appears that ESWT may be effective in the treatment of chronic diabetic foot ulcers. The purpose of this study is to evaluate the efficacy of ESWT in chronic foot ulcers, and to compared with that treated with HBO, and to study the molecular and blood flow perfusion before and after ESWT.

The purpose of this study is to evaluate the safety and efficacy of autologous bone marrow stem cell implantation for the treatment of leg ulcer in adult patients with sickle cell disease.

In this study, the investigators hypothesize that the use of olivamine-containing products in the management of patients with compromised nonhealing lower extremity ulcers is feasible in the Philippine setting. It will result in complete ulcer healing or wound closure after 16 weeks.

The hypertensive leg ulcer is a very painful leg related to acute skin microangiopathy. It occurs in patients older than 60 years followed for hypertension. Clinical diagnosis requires eliminating other causes arterial ulcers, cryoglobulinemia, thrombophilia, cholesterol crystal emboli, vasculitis associated with hepatitis C, myeloproliferative disorders and ulcers associated with the Hydrea ® outlet. There is no treatment of the ulcer because conventional treatments are ineffective. The pain has subsided by analgesics III. Other treatments are not effective outside skin grafts to be repeated because they necrotic regularly. In a prospective uncontrolled study, 11 patients healed through autohemotherapy. Ineffective treatment of this painful condition and efficiency of these cells to the damaged tissue, due to the secretion of many bioactive molecules, led us to propose subcutaneous injections of autologous fat to change the wound bed, promote healing and eliminate pain. This treatment should help to avoid long-term hospitalization (about 15 days) that can lead to physical and psychological degradation of these elderly patients. The investigators propose an open clinical study of 10 patients with a single-center recruitment (CHU Caen). The study took place over a period of 18 months with a 12-month recruitment and follow-up of 6 months for each patient. The purpose of this study was to evaluate the one hand, tolerance, in terms of pain and side effects, and, on the other hand, the effectiveness of this therapeutic approach, in terms of healing of the ulcer assuming a decrease in the size of the estimated at least 40% at 3 months wound. The measure of effectiveness will also focus on the changing appearance of the wound, including the relative areas of fibrin, necrosis and budding. These efficiency measures (area ratio) will be done through a computer program (CANVAS ®) on photographs taken at each assessment time. Eventually, if this study was to demonstrate the effectiveness of this treatment lipofilling, it would be possible to perform a multicenter study on a large number of patients to demonstrate the effectiveness, in terms of wound healing that the pain it causes and offer a shorter hospital stay, and in parallel, this approach should improve the pathophysiology of ulceration (translational research).

This is a double-blind randomized controlled clinical trial, that compares the percentage of epithelialization of skin defects using the conventional meshed split thickness skin grafts vs skin micro grafts. Two techniques will be applied in the same patient. The skin defect will be divided in two parts, and with a randomized method each half of this defect will be assigned to one of the two techniques.

The presence of pressure injuries has been considered a quality indicator of health care services and efforts has been made to develop guidelines to prevent this issue. Intensive care unit admissions (ICU) are recognized as risk factors to develop pressure injuries due to reduced mobility of critically ill patients and large number of devices and hard technologies that jeopardize preventive measures, such as, decubitus changes. There are not current definitive evidence about the superiority of any support surface to treat or prevent pressure injuries. The objective of the present study is to analyze if the use of viscoelastic support surface in vulnerable critically ill patients decreases the incidence of pressure injury compared with pyramidal foam support surface. Randomized clinical trial performed in an intensive care unit for adult patients in a philanthropic hospital. Inclusion criteria are patients admitted to ICU with Braden scale ≤ 14. Exclusion criteria are age under 18 years, less than 24 hours of ICU length of stay, contraindication of performing complete institutional preventive measures for support injuries, presence of support injuries at ICU admission or absence of informed consent. Randomization will be made by computerized generated numbers and patients will be allocated in two groups in a ratio of 1:1. All study patients will be cared for according to standard institutional preventive measures. The interventional group will be placed in an ICU bed with viscoelastic support surface and the control group in an ICU bed with pyramidal foam support surface. The main outcome evaluated will be the occurrence of type II pressure injury. Secondary outcomes are the time to the occurrence of pressure injury, length of ICU and hospital stay and 28 days mortality rate. Significance level will be 5%.

The etiology of non-healing ulcers depends on both systemic and local factors. The introduction of advanced dressing, negative wound therapy and compression therapy have undoubtedly improved clinical outcomes. The principal aim of study was to demonstrate the efficacy of skin micrografts in the treatment of skin substance loss.

GRegistry is a significant collection of data and information on the clinical practice of systemic scleroderma finger ulcers. The GRegistry study is a nationwide (Greece) prospective study recording, which includes consecutive patients with SC-DU diagnosis in clinical management departments of different hospitals, selected in such a way as to reflect a representation of the country. The use of Bosentan in the treatment of patients suffering from systemic sclerosis with digital ulcer disease is supported by data from large, placebo-controlled, randomized studies. The beneficial effect of Bosentan in digital ulcers, a vascular event of systemic sclerosis consistent with its beneficial effect on pulmonary arterial hypertension associated with connective tissue disease and its beneficial effect on vascular remodeling.

A single center, randomized, parallel, clinical outcome trial to compare the rate of healing in chronic wounds debrided with either high energy ultrasonic debridement (with cavitation) or standard of care sharp debridement.
