What is gout? Gout is a type of arthritis that causes pain and swelling in your joints, usually as flares that last for a week or two, and then go away. Gout flares often begin in your big toe or a lower limb. Gout happens when high levels of a substance called serum urate build up in your body. When this happens, needle-shaped crystals form in and around the joint. This leads to inflammation and arthritis of the joint. However, many people with high levels of serum urate will not develop gout. With early diagnosis, treatment, and lifestyle changes, gout
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 are autoimmune diseases? Autoimmune diseases refer to problems with the immune system, which usually fights off viruses, bacteria, and infection. The problem causes your immune cells to attack your body by mistake. These diseases can affect almost any part of the body.
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 are growth plate injuries? The growth plate is the area of tissue near the ends of long bones in children and teens that determines what length and shape the bone will be once it is done growing. Each long bone— the thigh bone, the bones in the forearm, and the bones in the hands and fingers—has at least two growth plates, one at each end. Once your child has finished growing, the growth plates close and are replaced by solid bone. The growth plates are weak areas of your child’s growing skeleton, making it easier to injure them. Injuries
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.
What is fibrous dysplasia? Fibrous dysplasia happens when abnormal fibrous (scar-like) tissue replaces healthy bone. The fibrous tissue weakens the bone over time, which can lead to: Broken bones. Bones that are misshapen (bowed or crooked). The disease can affect any bone in the body. Some people have no symptoms or only a few symptoms. Other people may have more symptoms. Although there is no cure for fibrous dysplasia, treatments may help to lessen pain, and physical therapy may help strengthen muscle and improve movement.
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
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.
