Rheumatology 

The main areas of rheumatology:

Rheumatoid arthritis:
A chronic inflammatory disease that affects the joints and leads to deformity and loss of function.
Treatment includes the use of anti-inflammatory drugs, immunosuppressants, and biological therapies.

Osteoarthritis:
A degenerative joint disease characterized by the destruction of cartilage.
Treatment includes exercise, pain medications and, in some cases, surgery such as arthroscopy or joint replacement.

Gout:
A disease caused by the deposition of uric acid crystals in the joints, resulting in sudden and intense pain.
Treatment is aimed at reducing uric acid levels in the blood and controlling inflammation.

Systemic lupus erythematosus (SLE):
An autoimmune disease that affects various organs and systems, including the skin, joints, kidneys, and nervous system.
Treatment includes the use of immunosuppressants, corticosteroids, and other drugs aimed at suppressing the immune response.

Ankylosing spondylitis: An inflammatory disease of the spine and sacroiliac joints that can lead to fusion of the vertebrae.
Treatment includes exercise, nonsteroidal anti-inflammatory drugs (NSAIDs), and biologic therapy.

Diagnostic methods in rheumatology:
Laboratory tests: Blood and urine tests to detect inflammatory markers and specific antibodies.
Radiological methods: X-rays, ultrasound, MRI and CT scans to visualize affected joints and tissues.
Biopsy: Taking tissue samples for histologic analysis.
