What about itchy fingers?

The etiology and pathogenesis of tinea manus is called Liriodendron chinense, and its pathogenic fungi are the same as tinea pedis, mainly Trichophyton rubrum. Clinical manifestations often start from a certain part of the hand, especially the side, flexion surface and palm of the thumb or forefinger, and then gradually expand. Its classification is the same as tinea pedis. However, because the palms are exposed, gangs rarely see the erosion between their fingers. But if it is caused by Candida albicans, erosion can be seen between fingers. Papular scale type often has small blisters and persistent annular scales. Blister itching is obvious, and if it happens near the palm and fingers, it is easy to get secondary infection. Overkeratinized palms and fingers are obviously keratinized and often wrinkle. The treatment is the same as tinea pedis. Besides actively treating tinea manuum, we should also prevent and treat tinea pedis, tinea corporis and onychomycosis. Pathological overview of tinea manuum, also known as Liriodendron, tinea manuum is an infection of dermatophytes in the palm. If only the back of the hand is involved and ring-shaped or multi-ring damage occurs, it is still called tinea corporis. Tinea manus is common all over the world, with a high incidence in China. Long-term immersion and friction injury of hands and contact with detergents and solvents are important causes of tinea manuum infection. Most of the patients are young and middle-aged women, and many of them have a history of wearing rings. Epidemic characteristics and pathogenesis can be used for external treatment of blister scale, such as miconazole cream, clotrimazole cream, compound benzoic acid liniment, compound rizosin liniment, etc. Keratinized thickening type can be soaked in compound benzoic acid ointment, miconazole cream or 10% glacial acetic acid. For chapped skin, urea oil can be added. After the lesions subside, medication should be used for at least 2 weeks. The frequency of applying medicine to hands should be increased appropriately, especially after washing hands, applying ointment or cream. Those with long course of disease or poor local treatment effect can take griseofulvin and ketoconazole orally. Or fluconazole 50%mg/ day or 150mg/ week for 2-4 weeks. Itraconazole 200mg/ day for one week. Muxiushu 250mg/ day for 2 weeks. To prevent onychomycosis and tinea manuum from infecting each other, it is necessary to treat tinea in other parts of the body at the same time. Try to avoid scratches and hot water burns. Avoid all kinds of detergents, soaps and organic solvents. There are two types of clinical manifestations: blister scale type: the onset is mostly a single case, starting from a certain part of the palm, especially the palm and root of the index finger and ring finger. At first, it was a needle-sized blister with thick and shiny walls and clear liquid. Blisters gather or disperse in groups, consciously itching. After drying, the blisters desquamate and gradually spread around to form annular or multi-annular lesions with clear edges and a chronic course of disease, which lasts for many years until all palms are involved and spread to the back of the hand and nails, and even to the opposite palms. Sometimes blisters can be secondary to infection and form pustules. Keratinized thickening type: it is mostly developed from blister scale type. The patient has a history of many years and often involves both hands. There is no obvious blister or annular desquamation, diffuse swelling and thickening of palm surface, deepened dermatoglyphics, rough skin, dry desquamation, easy chapping in winter, deep chapping and bleeding, unbearable pain, which affects activities. Besides dermatophytes, the factors that promote the keratinization and thickening of palms are also related to long-term scratching, washing and ironing, soap, detergent, various chemicals and solvents stimulation and improper handling. Diagnosis starts from a certain part of the palm, slowly expands, and finally involves most, all or even both palms. The lesions are erythema, blisters, scales and keratinization and thickening. The diagnosis should be considered as tinea manus, and the diagnosis can be made if the fungus test is positive. Differentiating the causes of complications, tinea manuum mostly comes from direct contact infection such as scratching tinea pedis, tinea cruris and tinea capitis, or the spread of onychomycosis and tinea corporis on the back of the hand. Trichophyton rubrum is the main pathogen of tinea manuum, accounting for 55.6%, followed by Trichophyton gypsum, accounting for 22.7%. Candida albicans can also cause the same damage as tinea manus. Is finger itchy and desquamate necessarily tinea manuum? Tinea manus, commonly known as Liriodendron chinense, is caused by fungal infection. Suffering from tinea manuum, you will often feel itchy, and the skin on your hands will also appear papules, blisters, erythema and desquamation. At first, it was a small piece, then the damage gradually expanded and the boundary was clear. After a long time, the hand skin will become rough, dry and thick, and may be accompanied by chapped and bleeding. But if there are symptoms such as itchy fingers and peeling, can you say that it must be tinea manus? Of course not. There are many skin diseases that can be manifested as itchy fingers and peeling skin, such as eczema, herpes zoster, contact dermatitis and exfoliative keratosis. , should be carefully identified, otherwise it will delay the diagnosis and treatment. Eczema often occurs in the palm of your hand, and your hands are symmetrical. Skin lesions are multiform, with papules, blisters, erosion, exudation and scabbing coexisting, and two or three of them are often dominant. The change of illness is closely related to the season, as well as diet and rest. If the palm comes into contact with water and soap, the injury will be aggravated. The fungal test was negative. The occurrence of herpes zoster has obvious seasonality, mostly at the turn of spring and summer, and it heals itself in winter, mainly among young people. Skin lesions are also symmetrically distributed, mainly blisters, which appear in batches and can be seen on the palm, fingertips and fingertips. Blisters fall off after drying out, exposing new skin, often accompanied by varying degrees of itching and burning sensation. The occurrence of this disease is related to poor sweating or allergic reaction, and the fungal examination of the damaged part is negative. Contact dermatitis is caused by contact with allergic substances, which is an allergic reaction of the skin and has obvious contact history. Skin lesions appear at the contact site, with clear boundaries and consistent shapes, mainly erythema and edema, and blisters and bullae can be seen in severe cases. After disengagement, it can gradually fade to recovery. Local fungal examination was negative. Exfoliative keratosis is a superficial exfoliative dermatosis of palmoplantar, often accompanied by local hyperhidrosis, which is prone to occur in warm and hot seasons. Skin lesions mainly involve hands, feet and bilateral symmetrical hearts, showing small white spots formed by loose keratin and easily falling off tissue-like scales. The underlying skin is normal and the itching is not obvious. The fungal test was negative. Suffering from tinea manuum, can I go to the kitchen? As we know, tinea manuum is caused by fungi, so it is contagious. Especially in the development stage of tinea manuum, the rash is very active, with erythema, papules, blisters and desquamation. At this time, fungi grow and reproduce quickly and are highly contagious. Because fungi will spread out with dander at any time, if you touch food with sick hands, the food will also be contaminated. But the infection of tinea manus is mainly through direct contact, such as shaking hands, not through food. Moreover, most foods are eaten after high-temperature cooking, and fungi have already been eliminated, which will not endanger people's health. So, can I go to the kitchen with tinea manus? Generally speaking, patients with tinea manuum will not cause infection even if they cook in the kitchen; Moreover, the fungus that causes tinea manus will not cause visceral diseases. But in order to ensure the health of consumers, patients with tinea manus are not allowed to work in the kitchen. So what should housewives and other people who do housework at home do if they suffer from tinea manus? First of all, we should treat it immediately. If it can't be cured for a while, it doesn't hurt to do some housework, but try to wash your hands before cooking. It's best not to touch cold food with your hands suffering from tinea manus, so as to reduce the chance of fungal contamination of food and ensure the cleanliness of food. Tinea manus is a chronic skin disease caused by superficial fungi, which is often infected by scratching tinea pedis without careful cleaning, so it often occurs from one hand. Because fungi are easy to reproduce in hot and humid seasons, their condition is easy to deteriorate in rainy or hot weather, with blisters, papules, scales and erosion. Chapped or horny in winter sometimes itches. But there are two basic characteristics: first, it is mostly unilateral localized rash, and the hot weather and cold weather only show dry skin, cracking, bleeding and pain. Second, fungi can be found in the dander on the rash. From this point of view, the most important difference between hand eczema and tinea manuum is to find fungi, especially before the onset of the disease without rubbing medicine in hot weather. Disease name: tinea manuum (Liriodendron) Disease introduction: tinea manuum is an infection of dermatophytes in the palm. If only the back of the hand is involved and ring-shaped or multi-ring damage occurs, it is still called tinea corporis. Tinea manus is common all over the world, with a high incidence in China. Long-term immersion and friction injury of hands and contact with detergents and solvents are important causes of tinea manuum infection. Most of the patients are young and middle-aged women, and many of them have a history of wearing rings. Pathogenesis: tinea manuum mostly comes from the direct contact infection of scratching tinea pedis, tinea cruris and tinea capitis or the spread of onychomycosis and tinea corporis on the back of hand. Trichophyton rubrum is the main pathogen of tinea manuum, accounting for 55.6%, followed by Trichophyton gypsum, accounting for 22.7%. Candida albicans can also cause the same damage as tinea manus. Clinical symptoms: there are two types: blister scale type, single onset. It starts from a certain part of the palm, especially the palm, side and root of the index finger and ring finger. It started as a needle-sized blister with bright walls and clear liquid. Blisters gather or disperse in groups, and feel itchy. After drying, the blister falls off and gradually spreads around, forming a ring-shaped or multi-ring injury with clear edges. Sometimes blisters can be secondary to infection and form pustules. Keratinization and thickening type: The patient has many years' medical history, often involving both hands, without obvious blisters or annular desquamation, diffuse swelling and thickening of the palm surface, deepened dermatoglyphics, rough skin, dry desquamation, chapped skin in winter, deep fissure bleeding, unbearable pain, affecting activities, and long-term scratching besides dermatophytes. Diagnosis: Starting from a certain part of the palm, slowly expanding, and finally involving most, all or even both palms. The lesions are erythema, blisters, scales and keratinization and thickening. The diagnosis should be considered as tinea manus, and the diagnosis can be made if the fungus test is positive. Auxiliary examination: scrape off scales, pick out blister solution and add 10%koH for microscopic examination, and separate hyphae can be seen. However, the positive rate of keratinized and thickened tinea manus is low and needs repeated examination. Take scales or blisters and inoculate them on Sheikh agar, and keep the temperature for culture, and colonies will grow within 2 weeks. According to the morphology and microscopic characteristics of colonies, strains can be identified. Treatment: The blister scale type can be externally applied with miconazole cream, clotrimazole cream, compound benzoic acid liniment, compound resin alcohol liniment, etc. Keratinized thickening type can be soaked in compound benzoic acid ointment, miconazole cream or 10% glacial acetic acid; For chapped skin, urea oil can be added. After the lesions subside, continue to use the drug for at least 2 weeks; Appropriately increase the frequency of hand medication, especially after washing hands, apply ointment or cream, and those with long course of disease or poor local treatment effect can take griseofulvin and ketoconazole orally; Or fluconazole 50%mg/ day or 150mg/ week for 2-4 weeks; Itraconazole 200mg/ day for one week; Muxiushu 250mg/ day for 2 weeks.
