Toe gout

Introduction It belongs to the category of traditional Chinese medicine, and it is known as the bones and the wind. It is a systemic disease characterized by chronic polyarticular inflammation. It is often caused by the onset of small joints of the hands and feet. It is often symmetrical. The early symptoms are pain, swelling, difficulty in movement and stiffness of the affected joints. Fingers, palms, and toes are dominant. Late symptoms of long-term unhealed are joint deformities.

Cause

Normal adults produce about 750 mg of uric acid per day, of which 80% are endogenous and 20% are exogenous uric acid. These uric acids enter the uric acid metabolism pool (about 1200 mg), and about 60% of the uric acid in the daily metabolic pool is metabolized. One third of about 200mg is catabolized by the intestine, and about 2/3 of about 400mg is excreted by the kidney, thereby maintaining the stability of uric acid level in the body, and any problem in any part can lead to hyperuricemia.

A normal blood uric acid should be repeated several times to avoid missed diagnosis. Some drugs that affect the excretion of blood uric acid by the kidney include salicylic acid, antihypertensive drugs, diuretics (hydrochlorothiazide), telden, dicoumarin, glycine, methicillin, acesulfame, Vitamin B, C and various X-ray contrast agents.

Differential diagnosis

Gout in the elderly is a high-risk disease in middle-aged and elderly people. Patients often have symptoms of gout prodrosis, which are characterized by migratory joint tingling, low heat fatigue, skin flushing, itching and so on. Older patients have more influence on multiple joints. Clinical manifestations Most patients have found hyperuricemia at the time of physical examination, but no clinical symptoms, blood uric acid >6.0bg / dL (360mol / L) is called hyperuricemia.
