Skin ulcers are open sores that are often accompanied by the sloughing-off of inflamed tissue.
Skin ulcers can be caused by a variety of events, such as trauma, exposure to heat or cold, problems with blood circulation, or irritation from exposure to corrosive material. Pressure ulcers, also known as decubitus ulcers or bedsores, are skin ulcers that develop on areas of the body where the blood supply has been reduced because of prolonged pressure; these may occur in people confined to bed or a chair, or in those who must wear a hard brace or plaster cast. Skin ulcers may become infected, with serious health consequences. Other health conditions that can cause skin ulcers include mouth ulcers (canker sores), chronic venous insufficiency, diabetes, infection, and peripheral vascular disease.
Symptoms
People with a skin ulcer may have an area of reddened skin. In advanced cases, people may have areas where the skin is open and oozing fluid.Holistic Options
A double-blind trial found systemic hyperbaric oxygen (HBO) treatments, in which the patient is placed in a chamber with highly concentrated oxygen, five days per week for six weeks significantly improved healing of non-diabetic chronic leg ulcers. This trial confirms the results from several preliminary studies of systemic HBO therapy.While topical application of HBO (the affected body part is encased in a balloon-like chamber and exposed to concentrated oxygen) for skin ulcers has been reported effective in preliminary trials,controlled trials have produced conflicting results. In controlled studies of diabetic patients with skin ulcers or gangrene, systemic HBO has been shown to prevent amputation of affected limbs.Electrical stimulation applied to the skin is thought to have several biological effects that might accelerate skin ulcer healing. A variety of techniques have been investigated, and controlled or double-blind trials have shown positive results for the use of low-voltage galvanic current, high-voltage pulsed current, transcutaneous electrical nerve stimulation (TENS), and pulsed high-frequency electromagnetic therapy.
