BACKGROUND Keloid and hypertrophic scars represent an aberrant response to the wound healing process. These scars are characterized by dysregulated growth with excessive collagen formation, and can be cosmetically and functionally disruptive to patients. OBJECTIVE Objectives are to describe the pathophysiology of keloid and hypertrophic scar, and to(More)
A new keratin-based hydrogel wound dressing was applied to the neck of a patient who was suffering from recessive dystrophic epidermolysis bullosa. A significant improvement was observed in the robustness of skin in this area: reduced propensity to blister and improved healing of blisters. The improvement allowed the cessation of use of secondary dressings(More)
Treatment of chronic wounds can present a challenge, with many patients remaining refractory to available advanced therapies. As such, there is a strong need for the development of new products. Unfortunately, despite this demand, few new wound-related drugs have been approved over the past decade. This is in part due to unsuccessful clinical trials and(More)
Linear porokeratosis is one of the infrequent variants of porokeratosis, a rare disorder of keratinization that may develop into several epidermal malignancies, among them squamous cell carcinoma. Clinical surveillance for malignancy is imperative, but in cases when large or many lesions are present, surgical removal of porokeratosis lesions would result in(More)
IMPORTANCE How complications associated with chronic venous insufficiency (CVI) develop is not clear. The central source of the complications is likely a dysfunction of the calf muscle pump, which includes veins and their valves, the gastrocnemius and other lower leg and foot muscles as well as the nerves supplying the muscles, and ankle mobility(More)
Chronic lower extremity ulcers are a significant burden on patients and health care systems worldwide. Although relatively common, these wounds can be difficult to treat and present a challenge to physicians. Treatment has often been based on anecdotal accounts; however, there is a growing emphasis on using evidence-based conclusions to guide clinical(More)
Diabetic foot ulcers (DFUs) represent an important clinical problem resulting in significant morbidity and mortality. Ongoing translational research studies strive to better understand molecular/cellular basis of DFU pathology that may lead to identification of novel treatment protocols. Tissue at the non-healing wound edge has been identified as one of(More)
Diabetic foot ulcers (DFUs) are a common complication of diabetes and present a significant health risk to patients, as well as impose a large economic burden. Evaluation for contributory factors that may impact general health or healing, such as hyperglycemia, peripheral artery disease, neuropathy, and nutritional status, is of the utmost importance.(More)
