In fact, this nail replacement is called "nail separation", which means the separation of the deck and nail bed. The reason is not clear. Some children are related to certain diseases such as hand, foot and mouth disease and scarlet fever, and some are related to the use of nail polish.
Ask carefully, it turns out that this child was infected with hand, foot and mouth disease by kindergarten children three months ago. So it can be confirmed that this nail separation is secondary to hand, foot and mouth disease, so don't be nervous. As the nails grow, they will gradually return to normal.
So, what is onychomycosis?
Onychomycosis, medically known as onychomycosis, is a kind of onychomycosis, which is an infection of deck or subungual tissue caused by various fungi. Fingernails and toenails can be infected. People with beriberi are more likely to get onychomycosis, so onychomycosis on their feet is more common.
The picture below shows the clinical classification of onychomycosis. However, no matter which one, it will never change. As long as the deck is thickened, damaged and discolored, and the auxiliary examination of "fungal microscopy+fungal culture" is positive, it can be completely diagnosed as onychomycosis.
But, but, but, please note that nails turn gray and yellow, and nails become thicker. Are they all onychomycosis? The answer is of course "no"! The key depends on whether your nails have fungal infection, otherwise, blindly taking medicine or even pulling out your nails without symptoms is not only time-consuming and laborious, but also full of disappointment, and even doctors will feel distressed for your heartbreak.
Yes, it is emphasized that fungal examination and fungal culture are the most direct and effective methods to diagnose onychomycosis without pain and trauma.
In order to show you better, the following common nail (toenail) problems are similar to onychomycosis. Let's identify their true faces:
1. Thickening of nails caused by trauma: Many patients have thickening of their little toes. According to clinical experience, their fungal examination results are mostly negative and will not develop to other toenails. This is often caused by improper wearing of shoes and long-term exercise friction, and onychomycosis is mostly manifested in the big toe on the foot. Patients in this situation don't have to worry, just reduce the squeezing and trauma to their toes.
2. Nail damage involved in chronic eczema: allergic constitution, eczema, especially hand and foot eczema patients, should pay attention. Finger eczema often appears blisters and desquamation repeatedly, which can affect nail development and lead to rough deck, which is quite similar to onychomycosis. In this case, the patient should start with eczema, and when the root of the disease is removed, A will naturally return to normal slowly.
3. Nail lesions involved in psoriasis: Nail lesions are more common in psoriasis, often showing a "sharp needle" depression. When the psoriasis lesions are relieved, the nail lesions will also be improved. Therefore, the source of treatment is the key.
If onychomycosis is diagnosed, how to treat it?
1. If only one or two nails have onychomycosis, and the degree is mild, antifungal drugs can be used externally;
2. However, if multiple nails are involved or serious, oral antifungal drugs are the most scientific and have the highest cure rate, but attention should be paid to the side effects on liver and kidney and drug interaction;
3. onychomycosis treatment is expensive! Never fish for three days and dry the net for two days;
4. The so-called magic medicine for treating onychomycosis advertised in the market is not efficient, so people are advised to choose carefully!
So how to prevent onychomycosis?
Healthy people are not easily infected with fungi. Friends who say that onychomycosis is discolored should not be overly nervous, and pay attention to the following precautions:
1. Fungi are more likely to grow in a humid and warm environment, so it is necessary to develop good hygiene habits. Usually try to penetrate air-soaked shoes and cotton sweat-absorbent socks, wash your feet frequently and change socks frequently, and shoes and socks are often exposed to the sun to keep dry.
2. Summer is a frequent season for tinea manus and pedis. People with sweaty hands and feet should pay special attention to it, and some treatments to inhibit local perspiration can be used appropriately;
3. Don't borrow daily necessities, such as shoes and socks, slippers, footbath, foot towel, etc. Don't share it with others, which is the key to prevent indirect infection of fungi;
4. Do a good job in environmental sanitation, and do not create an external environment for the growth and reproduction of pathogenic fungi, such as avoiding crowded and humid houses, paying attention to indoor ventilation, and often drying bedding and washing sheets. The daily necessities of patients with onychomycosis and tinea of hands and feet at home should be disinfected regularly with boiling water, and the items that cannot be burned should be disinfected by sunlight for 2-3 hours;
5. Strengthening the body's resistance, such as strengthening physical exercise, rational nutrition, and enhancing physical fitness, is conducive to improving the prevention of onychomycosis;
6. Some patients' onychomycosis evolved from tinea manus and pedis, so patients with beriberi should be actively treated to avoid the development of the disease and toenails.
