Filter by:The purpose of this study is to compare the effectiveness of Vacuum Assisted Closure® (V.A.C.®) Therapy to moist wound therapy of amputation wounds of the diabetic foot. The primary objective is to determine the effect of V.A.C.® Therapy on the incidence of complete wound closure. Secondary objectives include evaluating the acceleration of wound closure, facilitation of surgical closure, incidence of foot salvage, and incidence of wound complications.
The main objective of the proposed research study is to determine the potential utilization of [18-F] Fluorodeoxyglucose (FDG) positron emission tomography (PET) in patients with complicated diabetic foot, especially in the diagnosis or exclusion of osteomyelitis in this setting. We intend to validate and establish the necessary criteria for making such a diagnosis and determine the accuracy of the technique through comparison with other existing modalities, including MRI, and patient outcome. We expect that at the completion of the proposed research, the role of these powerful imaging modalities will be clearly defined in the management of patients with this challenging and serious complication.
The condition Charcot foot has been known in more than 130 years, and yet there still remains a large effort to find the cause, diagnostic and medical treatment of the condition. Charcot neuroarthropathy is a progressive disease of bone and joints characterized by often-painless bone and joint destruction in limbs that have lost sensory innervation. The incidence of acute Charcot among diabetic patients is 0,2 % the prevalence is 7,5 %. In the group of patients with neuropathy the prevalence is even higher –29%. The diagnosis is often made on a clinical basis, particularly in the early stages of the condition. The aim of this study is to find a method that makes the diagnosis primarily on the basis of paraclinical information. Clinical presentation: The typical patients have had diabetes in 10 years and have distal symmetrical neuropathy. The common lesion is unilateral with an acute phase, which may occur either spontaneously or be triggered by a minor trauma. The foot becomes swollen, warm, red and oedematous. Some patients have pain, and the condition could be misdiagnosed as cellulites, acute gout, deep vein thrombosis and osteomyelitis. If the patient has a foot ulcer it is important to rule out osteomyelitis and cellulites. In the initial phase it is difficult to make the right diagnose because Charcot is a rare condition. This leads to a delay in the treatment of the Charcot foot, which, for the moment, is reduction of weight bearing. The patient is equipped with an air cast, and the non weight-bearing regime is in some cases maintained in 12 months. The chronic Charcot is characterized by established deformity. The deformity can be in different sites in the foot, the most common is in the mid foot. Because of the deformity there is abnormal weight pressure on the weight bearing sites on the foot. This is associated with callus formation and there is a higher risk for ulceration.
Lower limb complications are a substantial matter in the diabetic population and studies show that the annual incidence of foot ulcers ranges from 1.0-4.1% while the cumulative lifetime incidence is approximately 15%. Foot ulcers may become complicated by infection or gangrene, and ultimately result in amputation. In addition, foot ulcers have a significant impact on quality of life (QoL). The treatment of diabetic foot ulcers has not made substantial progress in recent years with regards to improved healing although there have been several actions taken to update the process. The current practice consists of wound debridement, treatment of underlying infections and pressure relief. This trial investigates the adjunctive effects of high (80 mg) or low (10 mg) dose atorvastatin to conventional treatment on the healing of diabetic foot ulcers.
This is a Phase I, double blind, randomized, placebo-controlled study that will enroll approximately 50 adult subjects with Type 1 or Type 2 diabetes mellitus and chronic, diabetic foot ulcers. The study will be conducted at approximately 12 investigational sites in the United States.
Patients with diabetes may develop chronic wounds that respond poorly to treatment. Gene therapy with the platelet-derived growth factor-B gene has been shown to help with the healing of chronic wounds. This study will evaluate a new way to deliver the gene to the wound tissue.
Phase IV Open-Label Foot Infection Study is being conducted to generate comparative Efficacy and Safety data in Diabetic Inpatients.
The purpose of this study is to evaluate the efficacy and safety of REGRANEX® Gel compared with placebo when applied for up to 52 consecutive weeks to recurring or non-healing ulcers of the ankle or foot related to diabetes.
This is a randomized clinical trial to: (1) Determine the extent to which custom made study shoes will reduce the incidence of reulceration in diabetic individuals with prior history of foot ulcers, and (2) Estimate costs of ulcer prevention using these strategies.
This project will identify risk factors for diabetic foot ulcer by studying the relationship between endothelial dysfunction and foot ulcer risk. A fundamental defect in type 1 and 2 diabetic subjects is impaired vasodilatory reserve which is reflected in the dysfunction of endothelium-dependent vasodilation. Findings thus far point to an important role of the microvasculature in the development of diabetic foot ulcer and amputation. In this study a a well-characterized cohort of 750 diabetic veterans without foot ulcer will be followed over 3-years.
