Trichophyton (ringworm) - a fungal infection of the skin, caused by a parasitic fungi of the genus Trichophyton.After contact with skin, the fungus is introduced into it, starting to actively proliferate.If the spores germinate near the hair follicles, hair loss occurs.After the fungus feet, trichophytosis is perhaps the most common fungal infection.Most often suffer from trihofitii children (adults are much less likely, and younger women are more likely than men)
trihofitii ways of infection
main source of the disease are cats / kittens (less dogs, rodents and cattle).Trichophytosis Infection occurs through direct close contact with a sick animal or a person, or through the subjects infected wool flakes or infected animal.When injected into the soil with scales or hair, the fungus can remain viable for one to three months.Splash trihofitii often recorded in the autumn, many researchers have linked with the period of active agricultural operations
trihofitii symptoms and types
There are chronic, superficial and infiltrative - suppurative trichophytosis
Chronic trichophytosis majority of cases occur in women (frommen only 20% of the total number of infected adults), as well as in adolescents and is quite scarce clinical manifestations.This is due to the fact that emerged in childhood and not receiving proper treatment in time, in the period of puberty in boys' self-healing takes place, and the girls in front trichophytosis a protracted chronic.
on the scalp with chronic trihofitii observed small-sized lesions, having a form of black dots.On the smooth skin, the disease manifests purple - pink spots with flaky surface and do not have clearly defined borders.In chronic trihofitii most often affects the elbows, forearms, buttocks and lower leg;less body and face.Also in this form of the disease often occurs defeat nail plates, which begins with a gradually increasing small gray spots.After a certain period of time, the nail plate is deformed, it becomes lumpy, crumbles easily and gets dirty - gray with a yellowish tint
trihofitii superficial scalp mainly observed in the occipital region and shows multiple scaly in the center of round spots with a diameter of one centimeterhaving raised edges.In some cases, small foci may coalesce, thereby forming large enough destruction to several centimeters in diameter.The hair in the affected foci broken off at the level of the hair follicle.The skin in the area of centers of hyperemic and slightly swollen.In some cases, lesions emit exudate
trihofitii surface on the smooth skin takes the form of rounded bright - pink spots with clear boundaries.Lesions crusts, small bubbles or flakes.Over time, the inflammatory manifestation in the central parts begin to weaken, and the lesion gradually takes the form of a ring.Itching or completely absent or very weakly expressed.The most common surface trichophytosis smooth skin localized on exposed skin (trunk, forearms, neck, face)
trihofitii infiltrative - suppurative begins with the appearance on the skin of one or a group of well-defined scaly pale - pink spotswhich further due to peripheral growth start to increase in size and rise to the level of healthy skin.Over time, the inflammation in the centers (growth area mustache, beard, and scalp) grow - swelling and redness amplified;hemispherical form sharply defined bluish - red nodes which are lumpy surface covered with numerous erosions, folliculitis, and sometimes ulcerations.A characteristic feature of infiltrative - suppurative trihofitii are filled with pus expanded mouth of the hair follicles, which is released when pressed in the form of large drops or jets.On the smooth skin lesions in most cases take the form of flat plaques (sometimes quite large) with peripillyarnymi papules on the surface, which gradually transformed into pustular elements.The developed suppurative process resulting in the death of fungi and they are stored only on the periphery of the lesions.When infiltrative - suppurative trihofitii deteriorating overall health, there is a general malaise, increase in regional lymph nodes, increases the overall body temperature, headaches, increased erythrocyte sedimentation rate
diagnosis trichophytosis established on the basis of visual inspection, anamnesis, as well as instrumental and laboratory studies
Treatment trihofitii smooth skin without hair destruction is carried out by means of external antifungal drugs.In the morning hours on the affected pockets applied 2 - 5% tincture of iodine, and in the evening lesions smeared with antifungal ointment (sulfuric acid, sulfur - sulfur or Tar - salicylic ointment).In addition, twice a day, apply an ointment such as ciclopirox, clotrimazole, isoconazole, bifonazole etc.. Suffice well established drug Lamisil (terbinafine), which is available as a 1% cream or spray.
In the presence on the skin of multiple lesions, as well as in the defeat of the scalp (especially if you have been involved in the process of vellus hair), for several weeks carried out systemic antifungal therapy (in this case necessarily shave the hair).The main drug used in the treatment of this case is an antibiotic - griseofulvin.The drug must be taken every day during meals in three - four reception with a teaspoon of vegetable oil (oil is necessary to increase the duration of action and increase the solubility of the drug in the body).
