Filter by:Aim of the study: Evaluation of feasibility, safety and potential effects of stem cells on chronic wounds using a pressure sore model. Clinical relevance: - Accelerated healing of uncomplicated wounds - Enhanced healing of complicated (chronic, non-healing) wounds Study design: - Prospective controlled phase I/II study - Cohort of 5 patients in pilot study, then reevaluation Patients: - Para- and tetraplegic patients with sacral pressure sores grade III-IVA according to the classification of Daniel and Seiler Methods: 1. First surgical intervention: - Radical debridement of pressure sore - Bone marrow harvest from the iliac crest - Isolation of hematopoietic stem cells, aiming to gain > 1 mio. CD 34+ cells per patient under GMP conditions 3. Stem cell therapy (after 2 days) - Injection of stem cells in suspension (50'000 CD 34+ cells in 100 microliter saline per cm2 of wound surface) on one half of the total wound surface and cell-free saline on the other half as a control 4. Second surgical intervention (after 3-4 weeks): - Complete excision of the wound - Closure of the defect by fasciocutaneous flap 5. Evaluation of wound healing: - Clinical - 3D laser imaging - Histology - Growth factor assay
The study is a prospective randomised, controlled study of 136 patients undergoing vascular surgery. Their closed wounds were covered with either aquacel, a hydrofiber dressing, or a traditional gauze dressing.Number of changes, patient comfort,number of infections, length of hospital stay and wound complications were compared between the two groups.
The purpose of this study is to examine whether or not Low Level Laser Therapy (LLLT) can reduce pain and/or improve wound healing in patients with an acute traumatic injury to the upper extremity (wrist, forearm, or elbow).
The hypothesis is that topical opioids will hasten wound healing in humans.
This study will evaluate the effects of a protein called secretory leukocyte protease inhibitor (SLPI), on skin wound healing. Produced naturally by the body, SLPI modifies levels of elastase, a substance that breaks down the skin. Older people are at greater risk of impaired wound healing, with increased elastase activity and inflammation. In addition, men heal more slowly than women. Delayed healing is associated with infection and pain and can lead to the development of chronic non-healing skin wounds. Healthy men and women between 60 and 80 years old who wish to participate in this study will have a brief history and physical evaluation to determine their eligibility. Those enrolled will be randomly assigned to receive a gel form of SLPI applied topically (on the skin surface) to a skin wound or a placebo (a look-alike gel with no active ingredient). Participants will undergo the following procedures: First visit - The skin will be numbed with a local anesthetic and two small (4 mm) wounds (about the size of a pencil eraser) made in each upper arm. The drug or placebo will be applied to the wound and gauze placed over it. Two blood samples (20 ml and 7 ml) will be drawn an hour apart to determine blood levels of SLPI. Second visit - The day after the first visit, the wound dressing will be removed and the participant will be evaluated for pain at the wound site, allergic reactions or infection. A blood sample (7 ml) will be taken. Third visit - The wounds will be examined and photographed to evaluate healing. In addition, the strength of the wound may be assessed by means of a vacuum system placed on the skin. (This may cause a tingling sensation over the wound.) A piece of all four wounds will be removed after the skin has been numbed and a dressing applied. Fourth visit - The wounds will be examined for healing and the dressing removed.
