Differential diagnosis
Abdominal migraine must be distinguished from other causes of chronic or recurrent abdominal pain. These include irritable bowel syndrome, peptic ulcer disease, gastroesophageal reflux disease, mast cell activation syndrome, and celiac artery compression syndrome. It must also be distinguished from causes of acute abdominal pain, such as appendicitis, as wrong diagnosis may lead to unnecessary appendectomy. Treatment
Short term
Analgesia may be effective against abdominal migraine in some patients. Avoidance of intense light tends to have a short-term beneficial effect. Long term
Avoidance of triggers can be very helpful. Medications such as pizotifen, propanolol, and cyproheptadine may be used in rare circumstances. Prognosis
Abdominal migraine can have a significant impact on day-to-day life. Children may miss school or other activities. It resolves in many patients. Prognosis is generally good in children, but variable in adults. Epidemiology
Abdominal migraine primarily affects children, for whom it is a common cause of chronic abdominal pain. It may be as high as 9% or as low as 1% among children. It is rare in adults. However, children diagnosed with abdominal migraines may have migraine headaches as adults. The mean age of diagnosis is 7 years. It appears to be slightly more common in women.
Arthritis is a term often used to mean any disorder that affects joints. Symptoms generally include joint pain and stiffness. Other symptoms may include redness, warmth, swelling, and decreased range of motion of the affected joints. In some types of arthritis, other organs are also affected. Onset can be gradual or sudden.There are over 100 types of arthritis. The most common forms are osteoarthritis (degenerative joint disease) and rheumatoid arthritis. Osteoarthritis usually occurs with age and affects the fingers, knees, and hips. Rheumatoid arthritis is an autoimmune disorder that often affects the hands and feet. Other types include gout, lupus, fibromyalgia, and septic arthritis. They are all types of rheumatic disease.Treatment may include resting the joint and alternating between applying ice and heat. Weight loss and exercise may also be useful. Recommended medications may depend on the form of arthritis. These may include pain medications such as ibuprofen and paracetamol (acetaminophen). In some circumstances, a joint replacement may be useful.Osteoarthritis affects more than 3.8% of people, while rheumatoid arthritis affects about 0.24% of people. Gout affects about 1–2% of the Western population at some point in their lives. In Australia about 15% of people are affected by arthritis, while in the United States more than 20% have a type of arthritis. Overall the disease becomes more common with age. Arthritis is a common reason that people miss work and can result in a decreased quality of life. The term is derived from arthr- (meaning joint) and -itis (meaning inflammation).
