Does onychomycosis belong to dermatology?

Onychomycosis is a highly contagious skin disease. After the onset of this skin disease, the nails will grow very fast, and the color of the nails is different from that of normal people. The color of normal people's nails looks white with pink inside, and very smooth. After getting onychomycosis, the color of the nails looks gray. So, does onychomycosis belong to dermatology?

Onychomycosis belongs to dermatology.

There are many ways to treat onychomycosis, including external application of medicine, oral medication, and surgical removal of the diseased nail. The growth rates of fingernails and toenails are different. From the root to the front free edge, fingernails take 100 days, while toenails take about 300 days, which means that the growth rate of toenails is only 1/3 of that of fingernails. Therefore, patience is required to treat onychomycosis.

Surgical nail extraction is suitable for single onychomycosis. It can be performed under local anesthesia, or the diseased nail can be bandaged with a nail dissolving agent for 3 days before extraction. Since the growth of the nail starts from the root, the new nail can grow normally after the bad nail is removed. However, this method is very painful and difficult to accept.

Local application of the drug is less painful, but more time-consuming and laborious. The advantage is that it is more economical and easy to do. The method is to use a knife to scrape the diseased nail thinly every day, and then apply 30% glacial acetic acid 1 to 2 times a day until it is cured, which takes about 3 to 6 months. When applying the drug, you should pay attention to protecting the skin around the nail.

Oral antifungal drugs are suitable for patients with multiple nails (toenails) being sick at the same time. This method has long been used in clinical practice. For example, griseofulvin and ketoconazole absorption have certain curative effects, but they cannot be promoted due to their large toxic side effects. With the development of medicine, new drugs continue to emerge, which not only improve the efficacy but also greatly reduce the side effects. Now there is a new generation of itraconazole, which can be used for various fungal infections, especially for the treatment of onychomycosis. The specific method is to use shock treatment once a month, that is, 2 pills each time, twice a day, after meals, for 1 week, and stop the drug for 3 weeks as a shock course. Fingernails require two shock courses, and toenails require 3 shock courses. This method has good efficacy and few side effects, but the cost is relatively high, and some patients may still relapse after stopping the drug.

In short, the treatment of onychomycosis should be tailored to the individual and the place, and should be persistent. At the same time, we should also actively treat ringworms and chronic systemic diseases in other parts of the body, improve our own resistance, and pay equal attention to prevention and treatment. Only in this way can we completely cure onychomycosis.

Correct treatment for onychomycosis:

The dense structure of nails (toenails) hinders the penetration of topical drugs, which makes it difficult to treat onychomycosis. Therefore, onychomycosis has always been regarded as a stubborn disease.

After the direct topical application of drugs failed, people tried to remove the nails, that is, remove the nails and then apply topical drugs, but the effect was poor. Although anesthetics were used, the rich nerve endings at the fingertips still caused the patients unbearable pain.

It was not until the late 1980s that foreign countries found the real nemesis of onychomycosis - broad-spectrum antifungal oral drugs. It can really work from the inside out and cure the disease. Another advantage of oral drugs is that it avoids the trouble of applying the drugs every day, which is easy and convenient. At the same time, oral drugs can also treat tinea pedis, tinea corporis, tinea cruris, tinea capitis, etc., such as Sporanox capsules.
