The diagnosis must first be clarified before treatment, and the most reliable basis for diagnosis is a positive fungal microscopy and culture. Anti-ringworm treatment is then given after other dermatological conditions have been excluded. There are both systemic and topical medications for treatment, with topical medications generally being the mainstay because ringworm is parasitic in the cuticle and topical medications can kill it directly. If necessary, systemic medication is also used. Topical treatment: Different forms of topical medications are used according to the clinical typology of ringworm. There are many different types of medications, and each region has its own customary medication, so use them according to the local situation. 1. Blistering type: Small blisters occur on the plantar and foot edges, with thick walls, and form ring-like scales after drying. At this time can be used externally compound benzoic acid rub, compound lezosin solution, compound tincture of hibiscus, etc., with antibacterial and exfoliating effect. You can also use topical creams containing ciclopirox, bifenazole, econazole, ketoconazole, terbinafine, etc. It is usually applied 1-2 times a day. Apply for 3 days and stop for 3 days. Repeat the medication 3 – 5 times. 2, impregnated erosion type between the toes, especially between the third and fourth toes, the skin impregnated white. As a result of walking and constant friction, resulting in epidermal peeling, presenting a flushed vesicular surface, accompanied by a small amount of exudate. It is possible to use antibacterial or antiseptic powders or pastes such as foot powder, zinc ray paste, green peng paste, etc. to dry the lesions and heal the vesicles before applying topical drugs such as ciclopirox, bifenazole, econazole, ketoconazole, terbinafine, etc. Topical application can be irritating and cause pain when it comes to vesicles. 3, scaly hyperkeratosis type At first, there is mild inflammation and desquamation between the toes, gradually spreading to the foot plantar, foot edge and heel. Active lesions occur, erythema and papules, and even clusters of small blisters. Pruritus is aggravated. Keratosis mainly occurs on the plantar, foot edge or heel, showing rough skin, thickened keratinization, and easy chapping and pain in winter. Topical medication in the summer can be used alternately with tinctures and creams, in winter it is appropriate to use creams, ointments are mainly. In order to improve the efficacy of the drug after the addition of sealing package. You can use a plastic bag to cover your feet at night and take it off in the morning. 4. Secondary infections of tinea capitis and tinea pedis Local manifestations of redness, swelling, pain, erosion, and purulent discharge, accompanied by lymphadenitis and lymphangitis. The principle is to treat the secondary infection first, soak the foot with 1:5000 potassium permanganate, or do a cold wet compress with 0.1% Revnur solution or 3% boric acid solution, and apply topical antimicrobial ointments such as compound neomycin ointment, mupirocin ointment, and Dawei gang ointment. At the same time, the whole body with broad-spectrum antibacterial agent oral or injection. After the infection is controlled, then treat with antifungal drugs. Systemic treatment: For severe tinea pedis, often with secondary bacterial infections, systemic administration of medication may be considered. For example, terbinafine tablets, itraconazole, fluconazole, etc. are used, preferably under the guidance of a doctor. The criterion for curing tinea pedis is not the disappearance of symptoms, but preferably repeated negative bacterial checks, even more days after the disappearance of symptoms. However, since there are more pathogenic bacteria in nature and it is easy to re-infection, you should actively prevent it by applying preventive medicine regularly, once every 3-4 weeks, which can ensure that you do not get tinea pedis. So the key to break the root of tinea pedis is to prevent reinfection, and ringworm of the hands can also be treated according to the similar situation described above.
