BACKGROUND: Multiple organizations have issued guidelines to address the prevention, diagnosis and management of diabetic foot ulcers. These guidelines are based on evidence review and expert opinion. <p>METHODS: Literature review was conducted and guidelines were reviewed to identify consensus (or lack thereof) on the nature of these recommendations, the strength of the recommendations and the level of evidence.</p> <p>RESULTS: Most guidelines were not based on highest level of evidence (randomized controlled trials). A listing of recommendations for prevention, diagnosis and management was created with evidence basis for all recommendations.</p> <p>CONCLUSIONS: Areas for future research were identified among recommendations based on minimal evidence, areas of controversy, or in areas of clinical care without recommendations.</p>
Few scientific data are available on the effectiveness of commonly used modalities for reducing pressure at the site of neuropathic ulcers in persons with diabetes mellitus. The authors' aim was to compare the effectiveness of total contact casts, half-shoes, rigid-soled postoperative shoes, accommodative dressings made of felt and polyethylene foam, and removable walking casts in reducing peak plantar foot pressures at the site of neuropathic ulcerations in diabetics. Using an in-shoe pressure-measurement system, data from 32 midgait steps were collected for each treatment. There was a consistent pattern in the devices' effectiveness in reducing foot pressures at ulcer sites under the great toe and ball of the foot. Removable walking casts were as effective as or more effective than total contact casts. Half-shoes were consistently the third most effective modality, followed by accommodative dressings and rigid-soled postoperative shoes.
BACKGROUND:Diabetic foot ulceration is a severe complication of diabetes characterized by chronic inflammation and impaired wound healing. This study aims to evaluate the effect of a medical device gel based on Adelmidrol + Trans traumatic acid in the healing process of diabetic foot ulcers. METHODS: Thirty-seven diabetic patients with foot ulcers of mild/moderate grade were treated with the gel applied daily for 4 weeks on the affected area. The following parameters were evaluated at baseline and weekly: a) wound area, measured drawing a map of the ulcer then calculated with Photoshop6 tools, b) clinical appearance of the ulcer, assessed recording the presence/absence of dry/wet necrosis, infection, fibrin, neoepithelium, exudate, redness, granulation tissue. RESULTS: Topical treatment led to progressive healing of diabetic foot ulcers with a significant reduction of the wound area and an improvement in the clinical appearance of the ulcers. No adverse events treatment-related were observed. CONCLUSIONS: The results of this open-label study show the potential benefits of Adelmidrol + Trans traumatic acid topical administration to promote re-epithelialization of diabetic foot ulcers. Further studies need to confirm the observed results.
Background: Diabetic foot ulcers (DFUs) are main cause of hospitalizations and amputations in diabetic patients. Failure of standard foot care is the most important cause of impaired DFUs healing. Dakin's solution (DS; sodium hypochlorite) is a promising broad spectrum bactericidal antiseptic for DFUs management. Studies investigating the efficacy of using DS solution on DFUs healing process are scarce. Accordingly, this is the first evidence based randomized control trial study conducted to evaluate the effect of using diluted DS compared with the standard care in the management of infected DFUs. Methods: Randomized control trial study was conducted to assess the efficacy of DS in the management of infected DFUs. Patients were randomly distributed to control group (DFUs irrigated with normal saline) and intervention group (DFUs irrigated with 0.1% DS). Patients were followed for at least 24 weeks for healing, reinfection or amputations. In-vitro antimicrobial testing on DS was performed including determination of its minimum inhibitory concentration (MIC), minimum bactericidal concentration (MBC), minimum biofilm inhibitory concentration (MBIC), minimum biofilm eradication concentration (MBEC) and suspension test. Results: Replacing normal saline irrigation in DFU standard care with 0.1% DS followed by soaking the ulcer with commercial sodium hypochlorite (0.08 %) after patient discharge significantly improved ulcer healing (p< 0.001) and decreased number of amputations and hospitalizations (p< 0.001). The endpoint of death from any cause (RR 0.13; p = 0.029) and the amputation rate (RR 0.27; p<0.001) were also significantly reduced. The effect on ulcer closure (OR 11.9; p<0.001) was significantly enhanced in comparison to the control group. Moreover, DS irrigation for inpatients, significantly decreased bacterial load (p< 0.001), The in-vitro analysis results of DS were: MIC (1.44%), MBC (2.88%), MBIC (1.08%) and MBEC (2.87%). Conclusions: Compared with standard care, diluted DS (0.1%) was more effective in the management of infected DFUs. DS (0.1%) irrigation with debridement followed by standard care is a promising method in the management of infected DFUs.
Addressing pressure reduction in the treatment of diabetic foot wounds is a critical component of therapy. The total-contact cast has proven to be the gold standard of treatment because of its ability to reduce pressure and facilitate patient adherence to the off-loading regimen. Removable cast walkers have proven to be as effective as total-contact casts in pressure reduction, but this has not translated into equivalent time to healing. A simple technique to convert the removable cast walker into a device that is not as easily detached from the lower extremity, thereby encouraging the use of this device over a 24-hour period, is presented in this article. The procedure involves wrapping the cast walker with cohesive bandage or plaster of Paris. In the authors’ opinion, this technique addresses many of the disadvantages of the total-contact cast, resulting in an adequate compromise in this aspect of care.

Both vascular surgeons and podiatric physicians care for patients with diabetic foot ulcerations (DFUs), one of today's most challenging health-care populations in the United States. The prevalence of DFUs has steadily increased, along with the rising costs associated with care. Because of the numerous comorbidities affecting these patients, it is necessary to take a multidisciplinary approach in the management of these patients. Such efforts, primarily led by podiatric physicians and vascular surgeons, have been shown to effectively decrease major limb loss. Establishing an interprofessional partnership between vascular surgery and podiatric medicine can lead to an improvement in the delivery of care and outcomes of this vulnerable patient population.
This study analyzed the histologic effects of and host response to subdermally injected liquid silicone to augment soft-tissue cushioning of the bony prominences of the foot. A total of 148 postmortem and surgical specimens of pedal skin with attached soft tissue were obtained from 49 patients between July 1, 1974, and November 30, 2002. The longest period that silicone was in vivo was 38 years. The specimens were then processed into paraffin blocks and examined for specific findings. The variables considered included distribution of silicone within the tissue, host response, migration to regional lymph nodes, and viability of the host tissue after treatment. The host response to silicone therapy consisted primarily of delicate-to-robust fibrous deposition and histiocytic phagocytosis, with eventual formation of well-formed elliptic fibrous pads. The response in the foot appears different from that in the breast and other areas of the body previously studied. No examples of granulomas, chronic lymphoplasmacytic inflammation, or granulation tissue formation were seen, with only rare foreign-body giant cells present. Silicone injections in fat pads for the treatment of atrophy and loss of viable tissue show a histologically stable and biologically tolerated host response that is effective, with no evidence of any systemic changes.
