Tinea pedis (commonly known as "athlete's foot" or athlete's foot) is caused by a fungal infection. The skin damage often occurs on one side (i.e. one foot) first, and then becomes infected on the opposite side weeks or months later. Blisters mainly appear on the abdomen and sides of the toes, most commonly between the third and fourth toes, and can also appear on the soles of the feet. They are small deep blisters that can gradually merge into bullae. The skin lesions of tinea pedis have a characteristic that they have clear borders and can gradually expand outward. As the disease progresses or is scratched, erosion, exudation, or even bacterial infection, pustules, etc. may occur.

Causes of tinea pedis

Tinea pedis is a foot skin disease caused by pathogenic fungi and is contagious. Tinea pedis is widespread throughout the world and is more common in tropical and subtropical regions. In our country, the incidence of tinea pedis is also quite high. There are no sebaceous glands on the soles of human feet and between the toes, so they lack fatty acids to inhibit skin filamentous fungi and have poor physiological defense functions. However, the skin sweat glands in these parts are very rich and sweat more. In addition, the air circulation is poor and the local area is moist and warm. Conducive to the growth of filamentous fungi. In addition, the stratum corneum of the skin on the sole of the foot is thicker, and the keratin in the stratum corneum is a rich nutrient for fungi, which is conducive to the growth of fungi.

During pregnancy, women are susceptible to tinea pedis due to endocrine changes that reduce the ability of the skin to resist fungal infections. Obese people are prone to tinea pedis due to moisture between their toes and soaked in sweat. Trauma to the skin of the feet destroys the skin's defense function and is also one of the factors inducing tinea pedis. Diabetic patients are also prone to tinea pedis due to the lack of insulin leading to substance metabolism disorders and increased sugar content in the skin leading to reduced resistance. Abuse of antibiotics and long-term use of corticosteroids and immunosuppressants can cause imbalance in the normal flora of the skin and increase susceptibility to tinea pedis.

The onset of tinea pedis is also related to living habits. Some people do not pay attention to foot hygiene and footwear, which provides a good breeding ground for fungi.

Clinical manifestations of tinea manuum and pedis

The clinical manifestations are blisters between the toes, peeling, or the skin becomes white and soft, and erosion or skin thickening, roughness, cracking, and spread may also occur. Severe itching reaching the soles and edges of the feet. It may be accompanied by local suppuration, redness, swelling, pain, swollen inguinal lymph nodes, and even secondary infections such as calf erysipelas and cellulitis. Tinea manuum (tinea manuum) often occurs due to scratching the itchy areas with hands. Fungus grows on the nails, causing onychomycosis (onychomycosis). Fungi like a moist and warm environment. In summer, the weather is hot and sweaty, and people wearing rubber shoes and nylon socks provide a breeding ground for fungi. In winter, the condition often improves, manifesting as skin cracking. There are the following types:

1. Blister type

Most occur in summer, manifesting as rice-sized, deep blisters appearing between the toes, edges and soles of the feet, with evacuated or Distributed in groups, the blister wall is thick, the content is clear, and it is not easy to rupture. They merge with each other to form multi-room blisters. If the blister wall is torn off, a honeycomb base and bright red eroded surface can be seen, with severe itching.

2. Erosive type

It manifests as localized maceration and whitening of the epidermal cuticle. Due to constant friction while walking, the epidermis peels off, revealing a bright red eroded surface; in severe cases, the skin between the toes, the junction between the toe belly and the sole of the foot can be affected, and the itching is severe, mostly between the 3rd, 4th, and 5th toes. Common in people with excessive sweating.

3. Squamous keratosis type

The symptoms are thickening, roughness and desquamation of the skin on the soles of the feet, edges of the feet, heels and toes, and the scales are in the form of flakes or small dots. Falling off repeatedly.

Treatment of tinea manuum and pedis

1. Those with erosion and exudation between toes

Do not use strong irritating drugs externally. It is best to make the wound converge first Dry before applying. You can use 1:8000 potassium permanganate solution for wet compress, and then apply oil or powder externally. After the skin is dry, you can use terbinafine hydrochloride and other creams or ointments.

2. If the skin is severely keratinized and thickened, antifungal drugs are difficult to penetrate and absorb.

You can first use 10% salicylic acid ointment or compound benzoic acid ointment to soften the cuticles. Use antifungals again. If the skin is obviously dry and cracked, you can soak it in warm water each time to soften the cuticle, and then use antifungal drugs. For those with obvious dry and cracked skin, you can apply ointment locally after soaking in warm water each time, then seal it with a plastic film and wrap it with a bandage. Remove it after 24 to 48 hours, and then use antifungal drugs.

3. Those who have small blisters on their feet that have not burst

can first soak them in 3% boric acid solution, and then use antifungal creams such as bifonazole cream.

4. If tinea pedis is complicated by bacterial infection, in principle, local antibacterial infection should be treated first

You can use nitrofuracil solution or 1:2000 berberine solution for wet compresses. For severe infections, you can take it orally. Antibiotics, such as cephalexin capsules, erythromycin, etc.

5. Systemic treatment

For stubborn tinea pedis, oral medications can be given if there are no contraindications. Such as terbinafine, itraconazole, fluconazole, etc. These oral drugs are effective, but attention should be paid to their possible side effects and should not be used by people with poor liver function.

6. Adhere to medication

Tinea pedis is a chronic infection. The fungus grows and reproduces in the stratum corneum and requires long-term medication to completely remove it. Therefore, after the symptoms of tinea pedis are relieved, you still need to continue taking medication. The metabolic cycle of the skin is about 28 days, and the medication must be continued for more than four weeks. It is best to conduct fungal examination and culture. If it is negative for three consecutive weeks, it is considered cured.

7. Don’t use drugs indiscriminately

The most important thing about tinea pedis medication is to carry out consistent and regular treatment according to the classification. Do not treat blindly on your own, which often delays and aggravates the condition.

8. Medication should be based on the specific conditions of the lesion

Tinctures cannot be used on ulcerated areas. If the skin becomes thicker, ointment should be used on cracks.

9. When secondary infection occurs in tinea pedis and local acute inflammation occurs,

it cannot be treated as usual for tinea pedis. The secondary infection should be treated first. If there is redness and swelling, apply cold and warm compresses of boric acid water or nitrofuracil solution locally, and systemic antibiotics if necessary.

Prevention of tinea pedis

1. Pay attention to cleaning, keep the skin dry, keep the feet clean, wash them several times a day, and change socks frequently.

2. Foot basins and foot towels should be used separately to avoid infecting others.

3. It is not advisable to wear non-breathable shoes such as sports shoes, travel shoes, etc. to avoid excessive foot sweat and aggravation of foot odor. People with tight toe seams can use clean gauze or cotton balls sandwiched between the toes or choose split-toed socks to facilitate water absorption and ventilation.

4. Do not eat foods that easily cause sweating, such as peppers, raw onions, raw garlic, etc.

5. The mood should be calm. Excitement and agitation can easily induce excessive sweating and aggravate tinea pedis.

6. Tinea pedis is a contagious skin disease. You should avoid scratching to prevent self-infection and secondary infection.
