Dermatophyte is a common disease in skin diseases. Getting dermatophyte is really an uncomfortable thing. We must pay attention to it in ordinary life. Today, I'll introduce the causes of skin ringworm to you. I hope it will be helpful to you!
I. endocrine dysfunction
Clinical studies have found that female patients are related to menstruation and pregnancy. Most patients get better during menstruation and pregnancy. The improvement of skin lesions mostly occurs within 3-6 months after pregnancy, while most patients get worse after delivery, which may be related to the increased secretion of corticosteroids during pregnancy.
II. Infection factors
Local infection focus is an important cause of skin tinea, especially after a cold, complicated with tonsillitis and tracheitis, which needs active treatment to shorten the course of the disease as far as possible, and tonsil anti aggravating inflammation. These infections can activate some factors in the patient's body, so as to cause tinea bovis and worsen the condition.
III. allergic factors
Allergies caused by eating, taking drugs or contacting certain substances can often also induce skin ringworm. After the patient's condition worsens, we should carefully recall what substances caused it, so as to avoid exposure to such substances in the future.
IV. trauma
It is a common phenomenon after injury, such as burn, insect bite and skin scratch. These stimuli can cause skin damage, and then induce the occurrence of skin tinea.
V. mental factors
Skin is one of the expression organs of human internal psychological activities. Excessive mental tension is a non negligible inducement for the onset and deterioration of dermatophyte. Due to excessive mental tension, irritability, depression, irritability and insomnia, it accounts for the first of all other inducements, accounting for about 20%. Excessive mental tension produces a series of psychological or physiological reactions, promotes endocrine disorders, damages the body's immune defense system and enzyme metabolism disorders, thus promoting the occurrence of skin tinea.
1. Tinea corporis and tinea cruris: tinea corporis and tinea cruris refer to the infection of dermatophytes with smooth skin epidermis. Tinea cruris refers to tinea corporis that occurs in the groin, perineum, perianal and hip. At the initial stage of the disease, the skin turns red, with red spot papules and small water sores of large needle or grain size, but the edge is clear. With the progress of the disease, the skin lesions gradually expand outward, and the central part heals. Obvious water sores, mound herpes and concentric circles can be seen on the expanded edge, with large or small area and conscious pruritus. The incidence rate is influenced by many factors such as climate, occupation, living habits, health status, body resistance and so on.
2. Tinea capitis: tinea capitis is a dermatophytosis of scalp hair follicles, which can usually lead to inflammatory or non-inflammatory hair loss, mainly in pre adolescent children. There are three types of tinea capitis under the microscope: external type, internal type and tinea flavum. The clinical manifestations are hair loss and scales, often accompanied by inflammatory reaction.
3. Tinea manus and pedis: tinea manus and tinea pedis refer to the infection of dermatophytes on the skin of hands and feet except the back. In particular, tinea pedis is common, and the prevalence rate of the population is as high as 30% - 70%. The susceptible factors are humid climate, sweaty foot, less fat, partial lack of air and diabetes.
Tinea manus and pedis can be divided into three types: scaly keratosis, blister and abrasion.
Scaly keratosis is characterized by excessive skin keratosis, roughness, no sweat, dryness, scaly, keratosis and rupture, which can cause pain.
Blister type is characterized by scattered or clustered small deep blisters, which occur between palms and soles or fingers (toes). The conscious symptom is severe pruritus. Blisters can be secondary to infection, causing lymphadenitis and so on.
The rubbed type often exists in combination with the blister type. The skin on the toe surface is impregnated and white. The impregnated epidermis is is often removed due to scratching, exposing the ruddy wet rotten surface. It is easy to secondary bacterial infection, causing lymphangitis, erysipelas, cellulitis and so on.
4. Onychomycosis and onychomycosis: fungal infection of deck and subungual tissues caused by pathogenic fungi. Fungi often come from tinea manus and pedis. The fungi that invade the nails are mainly tinea rubrum. Most of the fungi that invade the toenails are tinea epidermidis, and a few are Candida albicans and tinea rubrum. It is a common and frequently occurring disease. The older you are, the more susceptible you are to infection. Patients with obesity and diabetes, HIV infection, abuse of antibiotics and impaired renal function are prone to develop the disease.
1. To prevent skin ringworm, we should first pay attention to hygiene, take a bath frequently, and keep ventilation at home. The humid environment provides good conditions for the growth of fungi. We should always open the doors and windows to make the indoor air convection and keep the room dry.
2. In summer, when the weather is hot, we'd better not go swimming in places with incomplete disinfection facilities, such as rivers and swimming pools with poor disinfection, because there are many people with skin fungal infection among swimmers. If the water is not disinfected thoroughly, it is easy to cause skin fungal infection.
3. Don't share towels, shoes, clothes and combs with people with tinea manus, tinea capitis and tinea pedis, because fungi can spread through these ways. If we don't pay attention to our usual living habits, we are easy to be infected with fungi.
4. After fungal infection, the skin will itch and desquamate, which will affect our health and life. If tinea pedis and tinea manus occur, we can use antifungal drugs with better effect. Before using antifungal drugs, we can soak our hands and feet in hot water, remove the soft skin and desquamate skin, and then apply the medicine continuously, The drug can not be stopped until the skin completely returns to normal for another week.
5. Those with severe tinea capitis will have running water, scab, pain and pruritus. Tinea capitis is easy to infect. After tinea capitis is cured, the pillow towel, comb and other items that contact the head should be disinfected and exposed to the sun to kill the fungi attached to it.
6. Patients with tinea manus and tinea pedis should be treated in time. If the treatment is not timely, the scope of fungal damage to the skin will expand. After tinea manus and tinea pedis are cured, the original shoes and socks that can be disinfected should be disinfected, and those that cannot be disinfected should be replaced with new ones, so as to prevent the residual fungi in the shoes from infecting the feet again and causing skin lesions.
7. People with skin ringworm had better eat more garlic at ordinary times. Garlic contains garlic capsaicin, which can fight against fungi.
