CausesThe disease is caused by the invasion of group A, type B hemolytic streptococci. The precipitating factors are mainly skin or mucosal abrasions or other minor trauma, but can also be caused by bloodstream infection. It is often secondary to rhinitis, oral mucosa and dental infection lesions. Tinea pedis, calf ulcers, pruritic dermatoses, inoculations, radioactive injuries, and chapped or slightly rubbed skin, scratching, and minor trauma can all trigger it. In particular, unclean wounds are more susceptible to infection. Some wounds can be so small that they are not easily detected, for example, facial dermatophytosis can be caused by a small wound in the nasal cavity that has been scratched. Recurrent dermatophytosis is caused by bacteria lurking in the lymphatic vessels, and can recur when the body’s resistance is reduced. Systemic diseases such as diabetes mellitus, chronic nephritis, hypogammaglobulinemia, and alcoholism can be triggers for the development of this disease. In infants, septicemia can occur and the mortality rate is high. The first choice of penicillin 4.8-8 million units / day static point, allergy with erythromycin 1 ~ 1, 5g / d static point or choose ciprofluoperazine 0, 2g / time, twice a day static point, oral Telbivitol 0, 2g / time, twice a day, can also be used to choose vanguardomycin V 6g / d static point or cephalosporin antibiotics. Generally 10 to 14 days is a course of treatment, which should be maintained for a period of time after the skin lesions have subsided. Sulfonamide drugs can also be taken internally. For recurrent dermatophytosis than the treatment of acute dermatophytosis medication should be longer, do not stop the drug too early, try to prevent recurrence, so as to avoid the continuous development of lymphedema. First, treatment: 1, systemic treatment. The principle is to remove the triggering factors, actively treat the primary lesion, and give the necessary supportive therapy to those with severe systemic symptoms. 2.Antibiotic treatment. The first choice is penicillin, which can be injected intravenously or intramuscularly, and the treatment should be insisted on for about 2 weeks after the body temperature returns to normal. Sulfonamides or other antibiotics can also be applied. 3, local treatment. The principle is anti-inflammatory. Local antibiotic ointment, dandruff ointment, 20% ichthyolite ointment or pure ichthyolite paste can be used. The area around the affected part can be coated with 2% tincture of iodine or wet compress with 0,1% epsom salicylic acid (Levanox) solution. For chronic recurrent tinea pedis and varicose veins of the lower limbs as its cause, helium-neon laser, ultraviolet light and superficial X-ray irradiation treatment is effective, and local injection of streptococcal antitoxin can prevent recurrence. 4.Chinese medical treatment.
