What is atopic dermatitis? Atopic dermatitis, often called eczema, is a chronic (long-lasting) disease that causes the skin to become inflamed and irritated, making it extremely itchy. Scratching leads to: Redness. Swelling. Cracking. “Weeping” clear fluid. Crusting. Scaling. In most cases, there are times when the disease is worse, called flares, followed by times when the skin improves or clears up entirely, called remissions. Atopic dermatitis is a common condition, and anyone can get the disease. However, it usually begins in childhood. Atopic dermatitis cannot be spread from person to person. No one knows what causes atopic dermatitis. Depending on
What is pemphigus? Pemphigus is a rare disease that causes blistering on many parts of the body, including the skin and the inside of the mouth, nose, throat, eyes, and genitals. In pemphigus, the immune system mistakenly attacks cells in the top layer of the skin.
What is ichthyosis? Ichthyosis is a group of skin disorders. It leads to dry, itchy skin that appears scaly, rough, and red. The symptoms can range from mild to severe. Ichthyosis can affect only the skin, but sometimes the disease can affect internal organs, too.
What is giant cell arteritis? Giant cell arteritis causes the arteries of the scalp and neck to become red, hot, swollen, or painful. The arteries most affected are those in the temples on either side of the head. These arteries narrow, so not enough blood can pass through. It is important that you get treatment right away. Otherwise, the arteries could be permanently damaged. There is also a risk of blindness or stroke. If you have giant cell arteritis, your doctor should also look for signs of another disorder, polymyalgia rheumatica. These conditions often occur together.
Integrins, a large class of cell surface molecules, play a role in a skin disease called scleroderma, according to research funded in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases and published in the journal Nature. The study showed that targeting integrins in mice with a form of scleroderma reversed the skin abnormalities associated with the disease. Scleroderma is a potentially life-threatening condition in which previously healthy people develop scarring of the skin, and in some cases damage to blood vessels and internal organs. In most forms of scleroderma, the cause of the disease is
A higher level of a small signaling molecule correlates with a more severe form of scleroderma, a chronic autoimmune disorder that involves the abnormal growth of connective tissue, according to a study funded in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases and published in The New England Journal of Medicine. The findings suggest that the molecule, CXCL4, could be used as a diagnostic marker for the disease and as a therapeutic target. Scleroderma is an autoimmune disease characterized by damage to blood vessels and thickening and scarring of the skin. In some cases, internal
