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 joint replacement surgery? Joint replacement surgery removes damaged or diseased parts of a joint and replaces them with new, man-made parts. Replacing a joint can reduce pain and help you move and feel better. Hips and knees are replaced most often. Other joints that can be replaced include the shoulders, fingers, ankles, and elbows.
What is pemphigus? Pemphigus is a type of disease where the body’s immune system attacks healthy cells in the top layer of skin (epidermis). It causes blisters on the skin and in the mouth, nose, throat, eyes, and genitals. Some forms of pemphigus can cause death if not treated.
What is lichen sclerosus? Lichen sclerosus is a long-term problem that usually affects the skin of the genital and anal areas. The disease can also appear on the upper body, breasts, and upper arms. The disease does not cause skin cancer but may increase your risk for cancer if your skin is scarred. You should see your doctor every 6 to 12 months in order to follow and treat skin changes.
Two new studies funded in part by NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) describe efforts to develop stem cell-based approaches for treating Epidermolysis Bullosa (EB), a rare, genetic skin disease. The findings, which were published jointly in the journal, Science Translational Medicine, may lead to individualized therapies for EB, and possibly other genetic diseases. People with EB have skin that is so fragile that the slightest friction causes blisters. The severity of the disease ranges from limited tearing of skin on the hands and feet to widespread blistering and scarring, including mucosal surfaces like the
What is epidermolysis bullosa? Epidermolysis bullosa is a group of rare diseases that cause fragile skin that leads to blisters and tearing. Tears, sores, and blisters in the skin happen when something rubs or bumps the skin. They can appear anywhere on the body. In severe cases, blisters may also develop inside the body. The symptoms of the disease usually begin at birth or during infancy and range from mild to severe.
A bioengineered molecule designed to bind together key components found in the fluid that surrounds joint areas may improve lubrication and minimize friction. This could potentially slow the degeneration of cartilage tissue that occurs in knee osteoarthritis, according to a study conducted in rats and funded in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases. The study was published in Nature Materials. The synovial fluid that bathes our joints is composed of several types of lubricants, including hyaluronic acid (HA) and lubricin. In healthy joints, this fluid ensures that tissues move together smoothly and without
What are knee problems? Knee problems happen when you injure or develop disease in your knee and it can’t do its job. The knees provide stable support for the body. They also allow your legs to bend and straighten. Both flexibility and stability are needed to stand, walk, run, crouch, jump, and turn. Other parts of your body help the knees do their job. These are: Bones. Cartilage. Muscles. Ligaments. Tendons.
What are sports injuries in youth? Although sports injuries can range from scrapes and bruises to serious brain and spinal cord injuries, most fall somewhere between the two extremes. Here are some of the more common types of injuries: Muscle sprains and strains. Injuries of a growth plate, area of tissue at the end of the long bones in growing children and teens. Injuries from overuse of muscles and tendons. Learn more about sports injuries.
Using magnetic resonance imaging (MRI), a team of scientists has detected structural changes in the knee joint that precede signs of osteoarthritis seen on X-rays. The study, which was supported in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS), calls into question the assumption that damage to cartilage is the primary underlying cause of osteoarthritis. The findings appeared in the journal Arthritis and Rheumatology.
