Disease characteristic of countries with low cultural and material level.
Favus (scab) is a fungal disease that affects the hair, skin, nails, and in some cases internal organs. The causative agent is the Trichophyton schonleinii mushroom.
Mostly women are ill. The disease remains unnoticed for a long time, therefore, patients are a constant source of infection, infecting their children and grandchildren.
Of great importance in the development of favus is the state of the organism and the level of personal hygiene. People with low immunity, diseases of the endocrine system, poor nutrition who do not comply with sanitary and hygiene rules, the disease progresses most likely. That is why the favus morbidity is very high in poor countries. It also promotes the appearance of a damp and hot climate.
The main symptoms of favus
The first manifestations of the disease occur approximately two weeks after infection. The fawus proceeds in one of three forms: sculptural, squamous or impetiginistic.
The most common is the sculptural form. Ripping on the skin, the mushroom is introduced into the stratum corneum of the epidermis and multiplied there, forming rounded yellow shields with a compression in the center - scraped. They consist of a culture of the fungus, cells of the epidermis and skin fat.
With a defeat of the scalp, the head of the hair becomes dull, brittle, and sluggish. They have a kind of "mouse" smell.
Hair falls out but does not break, which serves as a distinction of favus from other fungal diseases. Over time, the fungus penetrates deeper into the dermis, causing skin atrophy under scrapes. At this place a scar occurs, the hair does not grow there anymore. It also affects the skin on other parts of the body.
In the case of squamous forms rash occurs in the form of pink peeling spots, after which remain atrophic scars. Cutting is often very abundant, grayish-white scales, which is often taken by patients with dandruff.
For impetiginistic forms typical pustules and brown crust instead of scrappy, which also leave behind scars.
In addition to hair and skin at faucus, nails are affected. The fungus culture in the nail plate looks like a yellow stain. Over time, thickening and deformation of the nail develops. Most often, the brushes are struck, the disease occurs only with the generalized (general) form of infection.
Rarely, the favus affects the internal organs. With blood the mushroom is spread in the lungs, the brain, the gastrointestinal tract, the bones.
Favus is dangerous for the development of scarring on the scalp, leading to persistent baldness, as well as the possible severe damage to the internal organs.
When the typical sculptural form of the disease is diagnosed by the characteristic rashes and the state of hair is not difficult. The squamous and impetiginistic forms refer to the atypical varieties of the favus, which are difficult to diagnose. Patients with these forms of illness rarely turn to a doctor, thereby maintaining the focus of infection in their family.
The exact diagnosis is established after microscopic examination of hair and skin. If this is not enough, then conduct a culture study with the release of the culture of the fungus.
Treatment of fava includes the administration of antifungal drugs inside and out. If the hair on the head is shaken, then they are shaved once a week. Corsets soften with vaseline oil, and then removed. The skin is treated with antifungal lotions and ointments.
Mandatory reception of systemic antifungal agents with a wide spectrum of action.
