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 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 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 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 is rheumatoid arthritis? Rheumatoid arthritis (RA) is a chronic (long-lasting) disease that mostly affects joints, such as the wrist, hands, feet, spine, knees, and jaw. In joints, RA causes inflammation that leads to: Pain. Swelling Stiffness. Loss of function. Rheumatoid arthritis is an autoimmune disorder because the immune system attacks the healthy joint tissues. Normally, the immune system helps protect the body from infection and disease. RA may cause you to feel unusually tired, to have occasional fevers, and to have a loss of appetite. It also may cause other medical problems in the heart, lungs, blood, nerves, eyes
What is fibromyalgia? Fibromyalgia is a long-lasting or chronic disorder that causes muscle pain and fatigue (feeling tired). If you have fibromyalgia, you have pain and tenderness throughout your body. Sometimes you may have two or more chronic pain conditions at the same time, such as: Chronic fatigue syndrome. Endometriosis. Irritable bowel syndrome. Interstitial cystitis. Temporomandibular joint dysfunction (TMJ). Vulvodynia.
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.
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
Media Availability What: The U.S. Food and Drug Administration recently approved a new oral medication for the treatment of rheumatoid arthritis that represents a new class of drugs for the disease. The drug, tofacitinib (Xeljanz), provides a new treatment option for adults with moderately to severely active rheumatoid arthritis who have had an inadequate response to, or who are intolerant of, methotrexate, a standard therapy for the disease. Affecting nearly 1.5 million adults, rheumatoid arthritis is an inflammatory disease that causes pain, swelling, stiffness, and loss of function in the joints. It occurs when the immune system, which normally defends
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
The AMP® RA/SLE Program brings together the NIH and medical community to address rheumatoid arthritis and lupus with diagnostic and drug advancements.
