Modern medicine still can not answer the question of why some people are susceptible to defeat deprive the body, while others do not.In this regard, there are many versions, and neither one of them is not isolated as the most suitable.
According to experts working in this area (dermatologists) in the human body more susceptible to deprive a result of prolonged stress situations, as well as reducing the protective functions of the immune system.
Despite the fact that in most cases, lichens are the result of the defeat of the body's virus, they can also appear due to genetic predisposition.In the study of this disease and all its variants, it was observed that as a result of an allergic reaction caused by the intake of certain drugs may also receive zoster.
The risk of the disease include depriving people often fall ill acute respiratory diseases of viral nature, struck the body due to prolonged exposure.It is believed that in most cases ringworm is found in the more mature age from 30 to 70 years,
etiology (for) depriving quite diverse, everything depends on the individual characteristics of each person.For some there is a gradual loss of the skin, while others cover a rash once large areas of the body.
There are many species of lichen, depending on the form that has infected your body, different color rashes (from pale pink to red), the place of localization (the appearance is possible on any part of the body, but in most cases there is loss of limbs), the form of rash (possible not only peeling spots but blisters filled with liquid).
As mentioned, ringworm can affect any part of the body, less often the disease affects the skin of the neck, the surface of the back of the head, and the cases of the rash in the genital area and mouth very rare.It is known that not all species of lichen must be treated as some forms are on their own, without outside interference.
noted and latent (hidden) form the flow of the disease, the person may not notice as shingles strikes its skin, with this etiology (current) of the disease in most cases do not require special treatment.Still, shingles occurs more often with the symptoms that can be difficult not to notice the constant feeling of itching immediately attracts attention.
So who is it that is the causative agent of lichen?Most varieties of lichen cause microscopic fungi that enter the body.At the moment, we found a lot of varieties of these fungi which are the causative agents depriving.Among these species, there are those who can not live only on human skin, but also animals (zooantropofilnye mushrooms), and in such cases it is sufficient probable transmission of diseases from animals to humans.
addition, there are fungi that can not hit the animal organism and exert their influence on the people only (antropofilnymi fungi), and their transmission is performed only in close contact with an infected person.
third type of fungus - a geofilnye mushrooms, they are also capable of hitting the human body and of antropofilnymi different method of transmission, if the last case, it is in close contact with a sick person, in this case fungi enter the body in contact with the ground (their habitat).
the immune system of most people is at the level at which its defensive reaction enough to stop the vital activity of the fungus, which fell into the body, which saves man from the development of zoster.In cases where the immune system is weakened by a number of reasons (prolonged hypothermia, the struggle with the disease for a long period, children's age, HIV infection, frequent transfer of stressful situations), there is a rapid proliferation of the fungus in the layers of the skin, eats the fungus substance (keratin) contained in the stratum corneum of the skin.Severity of symptoms depends not only on the kind of fungus that hit the human body, but also on how the body reacted to outside interference in their work.
addition to fungi, pathogens may be depriving and viruses.They call such species as shingles in people of adult age (if it enters the body of a child causes chickenpox) and pink shingles have any category of people.The virus that causes these kinds of lichen, not always starting to show, but once in the body, it may be in an inactive state and wait for favorable conditions (lowering of the immune system).

Types of depriving a person
showing signs of depriving allowdetermine its species, but accurate diagnosis is necessary to visit a dermatologist as soon as he will be able to choose the right treatment.
Pink zoster (shingles Gibert) is still not fully understood, the exact cause of the now more is in question, according to some assumptions causative agent is a virus.
In most cases, the disease susceptible women, especially in spring and autumn, because in these times, our body is weakened as a result of hypothermia, vitamin deficiency and a number of other reasons.
Ringworm (trichophytosis) caused by fungi (trifitony) that infect the skin, that their name was the basis for the second title of the disease.Ringworm fungus is considered a type of herpes group.Fungi, is the causative agent of the disease are of two kinds: antropofilnymi and zooantropofilnye.Their fundamental differences have been described above.
In most cases, the variety most susceptible to robbing children, especially those who attend kindergartens or other pre-school institutions.Infection ringworm occurs due to prolonged close contact with an infected person or by sharing with them the use of personal hygiene items (comb) and clothing (hats).
Microsporia - is another fungal species of lichen, And there are times when microsporia confused with ringworm.The causative agents of these diseases are different, at mikrosporii this fungus, called mikrosporium Kanis (live in the fur of animals, mostly cats), it is different from the fungus that causes ringworm.Most often, the disease affects children, because they are by virtue of their curiosity constantly have contact with the animals, not only at home but also in the street.
Shingles is a viral species of lichen.It gets its development by ingestion of the herpes virus.Mostly localization are most often the intercostal nerves (the area between the ribs).Chickenpox is a form of herpes zoster (in children), adult skin it affects shingles.
of this disease comes amid postponed hypothermia, reduced functioning of the immune system in the presence of HIV in the elderly.Shingles most often affects people who are not ill with chicken pox as a child.
Pityriasis versicolor (multicolored) is a fungal species of lichen.
Lichen planus affects not only the skin but also the nail beds and mucous membranes.Risk group for the disease this kind of depriving were women aged 40 to 60 years, subject to biliary tract disease and digestive tract, as well as those suffering from diabetes.
Ringworm in humans, symptoms
Depending on the variety lichens also have a variety of symptoms.
When ringworm often falls under the lesion of the scalp.It originally appeared on it in the form of a rash of spots with jagged edges, at an inflammation of a feeling of itching.In most cases, the rash shelled and covered with a crust of white hair to break off their shoes at a short distance (1-3 mm) from the scalp (bald spots appear).
the first signs of ringworm after infection can occur immediately, but within 5 days.Ringworm affects the facial beard and mustache (men), hair and breaks off.In other parts of the body, where it is not so pronounced a hair cover, this kind of depriving expressed pale pink centers.When
pink shingles site localization is becoming the human body (chest, shoulders, back, the abdomen, skin folds).The rash is usually scaly and may be from pale pink to brownish hue, which is usually present around the rim of red.
usually on the skin of an infected person initially receive one spot, called maternal plaque, and then around him appear even more.Spot sizes range from a few millimeters to centimeters in diameter.The appearance of the rash is accompanied by a feeling of itching.When
zoster occurs central nervous system (nerve trunks at any location) that leads to pain along them.Also, there is a burning sensation and itching.Then, already appear on the skin rashes Vesicular character (bumps, inside of which is a liquid), which over time begin to burst, which brings even greater discomfort.
Nevertheless, after the fall away crusts, formed as a result of broken bumps on the skin does not remain traces.It is believed that when the first signs of this variety of depriving a person pronounced pain in the area of ribs and a strong sense of itching.Shingles affects not only the intercostal spaces, but other parts of the body, the main condition for when choosing a virus localization is the presence of large nerve trunks.With the development of the most serious form of this type may result in eye, which in some cases leads to loss of vision.
When microsporia on the scalp of the head appear rashes (spots of various sizes, in most cases, pale pink, flaky in the center, on the edge of a dark cushion), which lead to brittle hair at a distance of up to 10 centimeters to the root (for ringwormzoster, the figure is much smaller).The distribution of the species of lichen is not only on the head, the rash can also affect the neck and face, of course.When microsporia not usually a pronounced sense of itching.
When lichen planus patients often complain of a strong sense of itching in places where skin eruptions struck in the form of red bumps (purple-red) color, most often occurs in the presence of micro traumas of the skin.Mostly localization red lichen can be not only the skin but also the mucous membranes (clear, unlike other varieties stripping).
With further course of the disease bumps merge to form plaques quite large.If zoster struck mucous membranes, the observed light pink rash, sometimes gray.With the defeat of the nail plate begins its destruction by chopping.
When pityriasis versicolor lesions of the skin occurs as colorless scaly spots that are most noticeable on tanned skin areas.Small peeling areas of these spots can detect the disease and in areas with light skin.Color spots at pityriasis versicolor may vary.
Ringworm in humans, treatment
Upon detection on the body of the first signs of depriving should immediately contact an experienced, because only he can decide how to treat ringworm in your case in the fastest time possibleand with high efficiency.It depends on many factors, such as shown zoster, is considered the initial stage of the disease or a running event and many other factors.
Treatment pink lichen in some cases resolve spontaneously within 2 months, in other situations needs receiving antihistamines (reducing allergic reaction) such as "Zyrtec", "Tavegil."
Ringworm Treatment: Before treatment to completely shave off all his hair, and then lubricate the area 3-for-5% solution of iodine and at bedtime to lubricate the affected areas with sulfur-salicylic (tar) ointment.
microsporia Treatment in most cases is similar to the treatment of ringworm.
treatment of shingles: the emphasis in the appointment of treatment is to receive antiviral drugs, such as "Acyclovir", "Valacyclovir."
Treatment of tinea versicolor: based on the use of antifungal agents, in most cases, topically (gels, creams, solutions) drugs "Exoderil" and others.
Treatment planus: the first thing eliminated itching ("Tavegil" "Zyrtec"), then the therapy aimed at improving immunity.
