Current Clinical Trials Related to Dermatology
Actinic keratosis (AK) is the most common precancer that forms on skin damaged by chronic exposure to ultraviolet (UV) rays from the sun and/or indoor tanning. Solar keratosis is another name for the condition. AKs result from long-term exposure to ultraviolet (UV) radiation.
Symptoms of this allergic skin condition include itching, reddening, and flaking or peeling of the skin. This rash is usually seen in young infants but can occur later in individuals with personal or family histories of atopy, meaning asthma or allergic rhinitis. No matter which part of the skin is affected, eczema is almost always itchy. Sometimes the itching will start before the rash appears, but when it does, the rash most commonly appears on the face, back of the knees, wrists, hands, or feet. It may also affect other areas as well. Affected areas usually appear very dry, thickened, or scaly. In fair-skinned people, these areas may initially appear reddish and then turn brown.
Prurigo nodularis (PN) is a skin disease that causes hard, itchy lumps (nodules) to form on the skin. The itching (pruritus) can be intense, causing people to scratch themselves to the point of bleeding or pain. Scratching can cause more skin lesions to appear..
Urticaria, also known as hives, is an outbreak of swollen, pale red bumps or plaques (wheals) on the skin that appear suddenly — either as a result of the body’s reaction to certain allergens, or for unknown reasons. Hives usually cause itching, but may also burn or sting.
Other Types of Diseases Related to Dermatology
Rosacea is a common skin condition that causes redness and visible blood vessels in your face. It may also produce small, red, pus-filled bumps. These signs and symptoms may flare up for a period of weeks to months and then diminish for a while. While there’s no cure for rosacea, treatments can control and reduce the signs and symptoms.
Acne is a chronic inflammation of the skin that results in whiteheads, blackheads, pimples, cysts, or nodules. If not treated properly, it can leave skin scars. Our skin has pores that connect to oil glands under the skin and follicles connect the glands to the pores. These follicles are small sacs that produce and secrete a liquid. The glands produce an oily liquid called sebum which carries dead skin cells through the follicles to the surface of the skin. If these follicles get blocked and oil builds up under the skin it forms a pimple. Pimples can appear on the face, back, chest, shoulders, and neck.
Psoriasis is an immune-mediated disease that causes raised, red, scaly patches to appear on the skin. Psoriasis typically affects the outside of the elbows, knees or scalp, though it can appear on any location.
