What is osteogenesis imperfecta? Osteogenesis imperfecta (OI) is a disease that causes your bones to break (fracture) easily. OI is also called brittle bone disease. Your symptoms may be mild or severe, depending on the type of OI you have.
What is osteonecrosis? Your bones are made up of living cells that need a blood supply to stay healthy. In osteonecrosis, blood flow to part of a bone is reduced. This causes death of bone tissue, and the bone can eventually break down and the joint will collapse. Osteonecrosis can happen to any bone, but most often it develops in the ends of long bones, such as the: Thigh bone. Upper arm bone. Less often, the bones of the elbows, ankles, feet, wrists, and hands are affected. When the disease involves part of a bone in a joint, it can
What is tendinitis? Tendinitis is swelling and pain in a tendon, which is tissue that connects muscles to bones. It is a common condition, usually caused by repeated injuries to a tendon.
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 Marfan syndrome? Marfan syndrome is a genetic disorder that affects the body’s ability to make healthy connective tissue, which supports the bones, muscles, organs, and tissues in your body. The condition can affect different areas of the body, including: Bones, ligaments, tendons, and cartilage. Organs, such as the heart and lungs. Skin.
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
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
