OBJECTIVE: Diabetic foot ulcer (DFU), the major complication associated with diabetes mellitus, has been shown to precede amputation in up to 90% of cases. Recent data reveal that procalcitonin (PCT) is a valid marker for the diagnosis of bacterial infections compared with traditional markers like white blood cell count, C-reactive protein levels, and erythrocyte sedimentation rate in DFU patients. Furthermore, cytokines are proposed to act as modulators and mediators for the expression and release of PCT into the circulation...

Chronic wounds are a growing problem worldwide with no effective therapeutic treatments available. Our objective was to understand the composition of the dermal tissue surrounding venous leg ulcers and diabetic foot ulcers (DFU). We used novel 2-photon imaging techniques alongside classical histology to examine biopsies from the edges of two common types of chronic wound, venous leg ulcers and DFU. Compared to normal intact skin, we found that collagen levels are significantly reduced throughout the dermis of venous leg ulcer biopsies and DFU, with a reduction in both fibril thickness and abundance...

Chronic wounds (VLU: venous leg ulcer, DFU: diabetic foot ulcer, PU: pressure ulcer, or complex wounds) affect a significant proportion of the population. Despite appropriate standard wound care, such ulcers unfortunately may remain open for months or even years. The use of leukocyte- and platelet-rich fibrin (L-PRF) to cure skin ulcers is a simple and inexpensive method, widely used in some countries but unknown or neglected in most others. This auto-controlled prospective cohort study explored and quantified accurately for the first time the adjunctive benefits of topical applications of L-PRF in the management of such refractory ulcers in a diverse group of patients...

Diabetic foot ulcers (DFUs) are a serious and common problem in patients with diabetes mellitus and constitute one of the major causes of lower extremity amputation. The microbiological profile of DFUs depends on the acute or chronic character of the wound. Aerobic gram-positive cocci are the predominant organisms isolated from DFUs. Diabetic foot biopsies from patients admitted to the Angiology and Vascular Surgery Hospital of the Northeast, in Reynosa, Tamaulipas from December 2011 to April 2016 were analyzed...

BACKGROUND: Diabetic foot ulcer (DFU) is a devastating complication of diabetes. OBJECTIVES: We aimed to identify genetic contributors of DFU based on a genome-wide association study approach using a Scottish diabetic cohort. METHODS: A genome-wide association approach was applied. A case was defined as a diabetic patient (type 1 or type 2) who had ever been recorded in the linked e-health records as having a foot ulcer (current or previous) in at least one foot as well as a positive result of the monofilament test in the longitudinal e-health records...

The risk of adverse events (AEs) such as infection and amputation related to diabetic foot ulcers (DFUs) has been studied, but less is known about rate of other AEs such as falls. As part of a quality improvement project, AEs in veterans with diabetes mellitus (DM) with and without a DFU were examined. Demographic data including ICD-9 codes, AEs, and comorbidities for all patients with a diagnosis of DM and/or DFU treated between 2009 and 2014 at the James A. Haley Veterans' Hospital, Tampa, FL, were reviewed retrospectively utilizing the Corporate Data Warehouse (CDW) database...

Increasing evidence within the literature has identified the presence of biofilms in chronic wounds and proposed that they contribute to delayed wound healing. This research aimed to investigate the presence of biofilm in diabetic foot ulcers (DFUs) using microscopy and molecular approaches and define if these are predominantly mono- or multi-species. Secondary objectives were to correlate wound observations against microscopy results in ascertaining if clinical cues are useful in detecting wound biofilm. DFU tissue specimens were obtained from 65 subjects...

BACKGROUND: The lifetime risk of developing a diabetic foot ulcer (DFU) is at least 25%. A DFU carries a 50% risk for infection and at least 20% of those receive some form of amputation. The most significant parameter that prevents or delays ulcer healing is high plantar pressure. To improve the patient's healing process, the DFU's plantar pressure should remain cumulatively low. Therefore, a tool that continuously measures the DFU loading, and provides real-time feedback can improve the healing outcome...

Diabetic foot ulcer (DFU) is a frequent complication in diabetic patients, occurring in up to 25% of those affected. Among the treatments available to clinicians, the use of bioengineered skin substitutes is an attractive alternative. Artificial dermis functions as a matrix, covering the wound and supporting healing and reconstruction of the lost tissue. This study was aimed at reviewing the use of five regeneration matrices (namely, Integra, Nevelia, Matriderm, Pelnac, and Renoskin) as reported by clinical trials...
