matters needing attention
Early application of glucocorticoid can prevent systemic complications such as renal damage. The dosage of glucocorticoid should be determined according to the patient's condition. It can be given orally or slowly by intravenous drip. The dosage should be gradually reduced after the body temperature returns to normal and most of the skin lesions subside.
