What is Raynaud’s phenomenon? Raynaud’s phenomenon is a condition that affects your blood vessels. If you have Raynaud’s phenomenon, you have periods of time called “attacks” when your body does not send enough blood to the hands and feet. Attacks usually happen when you are cold or feeling stressed. During an attack, your fingers and toes may feel very cold or numb. Raynaud’s phenomenon is also called Raynaud’s disease or Raynaud’s syndrome.

https://www.niams.nih.gov/health-topics/lupus

What is systemic lupus erythematosus (lupus)? Systemic lupus erythematosus (lupus) is a chronic (long-lasting) autoimmune disease that can affect many parts of the body, including the: Skin. Joints. Heart. Lungs. Kidneys. Brain. Lupus happens when the immune system, which normally helps protect the body from infection and disease, attacks its own tissues. This attack causes inflammation and, in some cases, permanent tissue damage. If you have lupus, you may have times of illness (flares) and times of wellness (remission). Lupus flares can be mild to serious, and they do not follow a pattern. However, with treatment, many people with lupus

¿Qué es el lupus eritematoso sistémico (lupus)? El lupus eritematoso sistémico es una enfermedad autoinmunitaria crónica (de larga duración) y que puede afectar muchas partes del cuerpo, tales como: la piel las articulaciones el corazón los pulmones los riñones el cerebro. El lupus ocurre cuando el sistema inmunitario, que normalmente ayuda a proteger al cuerpo contra infecciones y enfermedades, ataca sus propios tejidos. Este ataque causa inflamación y, en algunos casos, daño permanente de los tejidos. Si usted tiene lupus, puede haber momentos en los que está enfermo (brotes) y períodos en que está bien (remisión). Los brotes de lupus

Giant Cell Arteritis

https://www.niams.nih.gov/health-topics/giant-cell-arteritis

What is giant cell arteritis? Giant cell arteritis causes the arteries of the scalp and neck to become red, hot, swollen, or painful. The arteries most affected are those in the temples on either side of the head. These arteries narrow, so not enough blood can pass through. It is important that you get treatment right away. Otherwise, the arteries could be permanently damaged. There is also a risk of blindness or stroke. If you have giant cell arteritis, your doctor should also look for signs of another disorder, polymyalgia rheumatica. These conditions often occur together.

Psoriasis

What is psoriasis? Psoriasis is a skin disease that causes red, scaly skin that may feel painful, swollen or hot. If you have psoriasis, you are more likely to get some other conditions, including: Psoriatic arthritis, a condition that causes joint pain and swelling. Cardiovascular problems, which affect the heart and blood circulation system. Obesity. High blood pressure. Diabetes. Some treatments for psoriasis can have serious side effects, so be sure to talk about them with your doctor and keep all your appointments.

Osteonecrosis

https://www.niams.nih.gov/health-topics/osteonecrosis

What is osteonecrosis? Osteonecrosis is a bone disease. It results from the loss of blood supply to the bone. Without blood, the bone tissue dies. This causes the bone to collapse. It may also cause the joints that surround the bone to collapse. If you have osteonecrosis, you may have pain or be limited in your physical activity. Osteonecrosis can develop in any bone, most often in the: Thigh bone (femur). Upper arm bone (humerus). Knees. Shoulders. Ankles. It is also called: Avascular necrosis. Aseptic necrosis. Ischemic necrosis.

Lupus Ban Đỏ Hệ Thống (lupus) là gì? Lupus ban đỏ hệ thống (lupus) là một bệnh tự miễn mạn tính (kéo dài) có thể ảnh hưởng đến nhiều bộ phận của cơ thể, bao gồm: Da. Khớp. Tim. Phổi. Thận. Não. Lupus xảy ra khi hệ miễn dịch, mà thường giúp bảo vệ cơ thể khỏi nhiễm trùng và bệnh tật, tấn công các mô của chính mình. Cuộc tấn công này gây viêm và dẫn đến tổn thương mô vĩnh viễn trong một số trường hợp. Nếu quý vị mắc bệnh lupus, quý vị có thể có khoảng

Bioengineered Compound May Aid in Treating Osteoarthritic Joints

https://www.niams.nih.gov/newsroom/spotlight-on-research/bioengineered-compound-may-aid-treating

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

MRI Findings Reveal Early Changes to Joint That Predict Development of Knee Osteoarthritis

https://www.niams.nih.gov/newsroom/spotlight-on-research/mri-findings-reveal-early-changes

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.

New Insights Into How Psoriasis Arises and How It Heals

https://www.niams.nih.gov/newsroom/spotlight-on-research/new-insights-how-psoriasis-arises

Psoriasis is a chronic skin condition characterized by itchy red patches and silvery scales, usually on the elbows, knees or scalp. It affects about 2 percent of Americans, and is sometimes associated with other health problems, such as arthritis, diabetes and heart disease. The causes are not fully understood, but the condition is related to an abnormal immune assault on skin cells that triggers inflammation. Scientists have been trying to understand the molecular details of what causes psoriasis. Now, two studies funded in part by the NIH’s National Institute of Arthritis and Musculoskeletal and Skin Diseases (NIAMS) and published in
