Diabetic foot ulcers stem from multiple factors, including peripheral neuropathy, high plantar pressures, decreased vascularity, and impaired wound healing. Contributing significantly to morbidity, they may cause limb loss and death. (See Foot ulcers and diabetes.)
Initially, hydrocolloid dressings were developed to function as part of the stomal flange. Based on their success in protecting peristomal skin, they were introduced gradually into other areas of wound care. They contain wafers of gel-forming polymers, such as gelatin, pectin, and cellulose agents, within a flexible water-resistant outer layer. The wafers absorb wound exudate, forming a gel and creating a moist healing environment. (more…)

A hydrocolloid dressing is a wafer type of dressing that contains gel-forming agents in an adhesive compound laminated onto a flexible, water-resistant outer layer. Some formulations contain an alginate to increase absorption capabilities. The wafers are self-adhering and available with or without an adhesive border and in various thicknesses and precut shapes for such body areas as the sacrum, elbows, and heels.

At a time when governments are under pressure to reduce healthcare costs, the global advanced wound care market is growing, driven by an aging population and rising incidences of chronic wounds.
Advanced wound care products are typically used to manage complex wounds, including burns, chronic wounds and complex trauma and surgical wounds. Chronic and complex wounds represent one of the predominant challenges to global healthcare systems because they are hard to heal and expensive to treat. (more…)
Negative pressure wound therapy (NPWT) uses negative pressure to draw wound edges together, remove edema and infectious material, and promote perfusion and granulation tissue development. The tissue stretch and compression created by negative pressure during NPWT promotes tissue perfusion and granulation tissue development through angiogenesis, cellular proliferation, fibroblast migration, increased production of wound healing proteins, and reduction of wound area. NPWT has been used to improve healing in a variety of wounds, including traumatic injuries, surgical wounds, pressure ulcers, diabetic foot ulcers, and venous stasis ulcers. (more…)
According to the National Cancer Institute, an estimated 1.6 million new cases of cancer will have been diagnosed in the United States in 2015. During the course of their disease, most cancer patients receive radiation therapy.
Delivering high energy in the form of waves or particles, radiation therapy alters the DNA of cancer cells, causing their death. Radiation can be administered either externally or internally (through materials placed into the body). It’s given in fraction doses, with the total recommended dose divided into daily amounts. Treatment, including the total dose, is determined on an individual basis.
Although improvements have been made in delivery of radiation therapy, approximately 95% of patients who receive it experience a skin reaction. What’s more, radiation therapy commonly is given concurrently with chemotherapy or targeted therapy to improve survival, which increases the toxicity risk. (more…)
