What is pachyonychia congenita? Pachyonychia congenita is a very rare disorder. It causes thick nails and painful calluses on the bottoms of the feet. In some cases, blisters also form on the palms of the hands.
Is your back hurting? You’re in good company. In any 3-month period, about 1 in 4 adults in the U.S. has at least one day of back pain, mostly in the lower back. The back is a complicated structure. Its center is the spine, which is made up of 33 bones called vertebrae, stacked in a column. The nerves of the spinal cord run in a tunnel through the middle of those bones. Spongy discs between the vertebrae act as cushions. Ligaments and tendons hold everything together. A lot of things can go wrong with your back. A strained muscle
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.
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
What is scleroderma? Scleroderma is an autoimmune connective tissue and rheumatic disease that causes inflammation in the skin and other areas of the body. This inflammation leads to patches of tight, hard skin. Scleroderma involves many systems in your body. A connective tissue disease is one that affects tissues such as skin, tendons, and cartilage. There are two major types of scleroderma: Localized scleroderma only affects the skin and the structures directly under the skin. Systemic scleroderma, also called systemic sclerosis, affects many systems in the body. This is the more serious type of scleroderma and can damage your blood
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 Sjögren’s syndrome? Sjögren’s syndrome is a chronic (long-lasting) disorder that happens when the immune system attacks the glands that make moisture in the eyes, mouth, and other parts of the body. The main symptoms are dry eyes and mouth, but the disorder may affect other parts of the body. Many people with Sjogren’s syndrome say they feel tired often (fatigue). They also may have joint and muscle pain. In addition, the disease can damage the lungs, kidneys, and nervous system.
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 back pain? Back pain is one of the most common medical problems in the United States. It might feel like a dull, constant ache or a sudden, sharp pain. Back pain can result from: An accident. A fall. Lifting something heavy. Changes that happen in the spine as you age. A disorder or medical condition. Treatment depends on the cause and symptoms of your pain. You can do things to improve your health and lower your chance of developing chronic (long-lasting) back pain.
What are heritable disorders of connective tissue? There are more than 200 heritable disorders of connective tissue that can affect the tissues between the cells of your body that give tissues form and strength. All of these diseases are directly related to problems in genes that are responsible for building connective tissues. The disorders are called “heritable,” because they are passed on from parent to child. Some heritable disorders of connective tissue change the look and growth of skin, bones, joints, heart, blood vessels, lungs, eyes, and ears. Others change how these tissues work. Many, but not all, are rare
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
