beriberi
Introduction
Introduction Athlete's foot is a very common fungal infectious skin disease. 70-80% of adults have athlete's foot, just different weights. Often aggravated in summer, reduced in winter, and some people do not heal all year round. Athlete's foot is the common name of the foot. Some people confuse "foot athlete's foot" with "foot athlete's disease". This is not right. Medical "beriberi" is a systemic disease caused by vitamin B deficiency, and "foot athlete" is a common skin disease caused by fungal (also known as germ) infection. Footbaths and foot towels should be used separately to avoid infecting others. If the foot is not treated in time, sometimes other parts, such as causing handcuffs and hyperthyroidism, sometimes because the itch is scratched, secondary bacterial infection, can cause serious complications. Chinese medicine said that athlete's foot is "weak feet." "Prepare for the urgent need" Volume 22 "Feng poisoning athlete's foot": "Rather, this disease begins, first from the foot, because it is swollen, when the number is athlete's foot. Shen Shiyun: weak feet, that is Its righteousness too."
Cause
Cause
The pathogenic bacteria are many species of Trichophyton species and Epidermidis, and the main strains are Trichophyton rubrum, Gypsum-like Trichophyton, Floccular epidermidis, Trichophyton rubrum. Because of its strong resistance and difficult to control, Trichophyton rubrum has become the main pathogen of the current ankle in China.
Athlete's foot is a mild mycosis that invades the epidermis, hair and toenails, and is an infectious skin disease. The vast majority of patients are suffering from athlete's foot re-infection to the hands and other parts. The main reasons for the high prevalence of athlete's foot are as follows:
First, the skin of the foot and ankle has no sebaceous glands, and lacks fatty acids that inhibit mold.
Second, the skin and sweat glands of the ankle and foot are richer, sweating more, resulting in a humid environment conducive to mold growth.
Third, the skin and stratum corneum of the ankle and foot are thicker, and the keratin protein in the stratum corneum is a nutrient for mold growth.
Fourth, in addition to wearing shoes and socks, the local environment is stuffy, and the sweat is difficult to pass through and moist, which is more conducive to the growth and reproduction of mold.
The disease can be induced by sweating on the feet or not ventilating the shoes and socks. Dermatophytes are often transmitted through contaminated bathhouses, poolside floors, bath towels, communal slippers, and footbaths.
Examine
an examination
Medically, athlete's foot is usually divided into three types: erosive, blister, and keratotic athlete's foot.
1. Erosion type: occurs in the third and fourth, fourth and fifth toes. At the beginning, the toes are damp, immersed in white or small blisters, and after dryness and desquamation, the dandruff is peeled off into a moist, flushed smashed surface, which is itchy and easy to be infected.
2. Blister type: occurs in the foot edge. From the beginning, there are small blisters with full thickness, some can be fused into bullae, the blister is transparent, and there is no redness around. It is consciously itchy, and it often causes erysipelas and lymphangitis due to secondary infection.
3. Keratinized type: It is good for the heel. Mainly manifested as thick and dry skin, keratinized desquamation, itching, prone to chapped. This type of no blister and suppuration, the course of the disease is slow, and has not healed for many years.
Diagnosis
Differential diagnosis
According to typical clinical manifestations, diagnosis is not difficult. However, atypical hand, foot and ankle are often confused with hand and foot eczema, palmoplantar pustulosis and sweat herpes. It should be noted that fungal examination often helps to confirm the diagnosis.
Eczema is a common inflammatory skin disease caused by a variety of internal and external factors in the epidermis and dermis. It is characterized by conscious and intense itching, morphological lesions, symmetric distribution, tendency to exude, chronic course, and easy recurrence. Medically, athlete's foot is usually divided into three types: erosive, blister, and keratotic athlete's foot.
