What is pachyonychia congenita? Pachyonychia congenita (PC) is a very rare genetic disorder that affects the skin and nails. Most people have thickened nails and calluses on the bottom of the feet. Painful calluses on the soles can make walking difficult. Because of the pain, some people rely on a cane, crutches, or a wheelchair to help with walking.
What is reactive arthritis? Reactive arthritis happens when an infection causes joint pain and swelling. A bacterial infection in the digestive or urinary tract or the genitals usually triggers the condition, but arthritis symptoms typically do not start until a few weeks after you have recovered from the infection. The most common features of reactive arthritis are inflammation of the joints (especially the knees and ankles), eyes, and urinary tract, but not everyone gets all three, or they might not happen at the same time.
What is osteoarthritis? Osteoarthritis is a joint disease that happens when the tissues in the joint break down over time. It is the most common type of arthritis and is more common in older people. People with osteoarthritis usually have joint pain and, after rest, stiffness (inability to move easily) for a short period of time. The most commonly affected joints include the: Hands (ends of the fingers and at the base and ends of the thumbs). Knees. Hips. Neck. Lower back. Osteoarthritis affects each person differently. For some people, osteoarthritis does not affect day-to-day activities. For others, it causes
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 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 spinal stenosis? Spinal stenosis happens when the spaces in the spine narrow and create pressure on the spinal cord and nerve roots. The spinal cord is a bundle of nerves that comes out of the base of the brain and runs down the center of the spine. The nerve roots branch out from the cord. In spinal stenosis, the narrowing usually occurs over time.
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 rosacea? Rosacea (ro-ZAY-she-ah) is a long-term skin condition that causes reddened skin and a rash, usually on the nose and cheeks. It may also cause eye problems.
The human back is a complex structure with bones, nerves, tendons, discs, and more — all places where something can go wrong and cause pain, which, for many people, becomes a long-term or chronic problem. Life stresses and other medical and mental health conditions aggravate the problem. With so many pieces, it’s hard to get a holistic view of the puzzle or pinpoint the cause of the pain. “People tend to focus on one aspect or another,” said Jeffrey Lotz, Ph.D., a medical engineer who studies back pain at the University of California, San Francisco. “Some people think it’s largely
Discussing Bone, Muscle, Skin, & Autoimmune Diseases: Info for American Indians, Alaska Natives - audio
A conversation between Dr. David R. Wilson, director of the NIH Tribal Health Research Office, and Dr. Lindsey A. Criswell, director of NIAMS, about information and resources for American Indians and Alaska Natives related to bone, muscle, skin, and autoimmune diseases.
A research team led by Dr. Makarand Risbud of Thomas Jefferson University tested whether treatment with the drugs dasatinib and quercetin would prevent disc degeneration in mice. Both drugs are senolytics, which selectively remove aged cells known as senescent cells.
NIBIB-funded researchers are developing an implantable, biodegradable film that helps to regenerate the native cartilage at the site of damage. Their study, performed in rabbits, could be an initial, important step in the establishment of a new treatment for this common condition, osteoarthritis.
