    Etiology and pathogenesis of a demodekoz

    The tick of Demodex folliculorum causing was found in 1842. Today 65 species of a tick are known, but only three of them strike the person, the others parasitize only on animals. Habitats of a tick – a sebaceous gland and hair follicles; the favourite place of localization - a chin, a nose; can meet on eyebrows and eyelashes, in the latter case blefarita develop.

    The size of an adult individual about 0,3-0,4 mm, and its little body is covered with scales thanks to which the tick strongly is fixed in hair follicles. The tick eats skin fat and hormones of the person. Pincers avoid daylight, and therefore come to the surface of skin only in night-time, as explains the itch and discomfortable feelings at a demodekoza amplifying by the evening.

       Life cycle of the activator of a demodekoz makes several weeks, during this time the female is capable to make not one laying of eggs, but the amount of eggs in a laying can reach several tens. In 3-4 days there are new individuals who in a week are already ready to reproduction. Old individuals of a tick die and decay in hair follicles.

    Kleshchik is found in 90% of the population, but he does not cause a demodekoz whereas others cannot recover a long time in one people. If in a follicle single individuals are found, then it is not a reason for concern, in this case the activator of a demodekoz is inactive and practically does not breed.

    The trigger when the kleshchik begins to breed promptly, up to the end is not studied, but the people having stresses, nerve strains because all this intensifies production of skin fat which creates favorable conditions for activity of a tick get into risk group. Decrease in immunity, tendency to skin a disease, spicy food, long insolation, hobby for baths and saunas also causes activization of the activator of a demodekoz.

    Besides use of cosmetics containing hormonal medicines at many women as a result leads to emergence of a demodekoz as hormones and nutrients in creams is its favourite food. At such way of infection to a jar with cream individuals of a demodeks daily get, and then cream bears not beauty and youth, but a serious disease. Of course, does not involve deep violations, but face skin spoils, besides at extensive defeats perhaps secondary infection with pathogenic microflora that even more complicates a current of a demodekoz.

    Women with the friable and sensitive skin inclined to reddenings get into risk group, most often it is blondes or brown-haired women. occurs at men less often, it is connected with shaving as the horny layer of skin almost daily is removed and the kleshchik cannot become stronger in skin layers.

    If the immune system of the person is not broken, then does not arise as the parasite does not get out of limits of a basal membrane, but if reception of hormonal medicines is conducted or there are standings at which there is an activization of immune system, then the structure of skin changes and the probability of a demodekoz sharply increases. The combination of all or several pathogenetic mechanisms increases probability of developing of a disease though cases are not rare that diagnose for people who do not get into one risk group.

    Manifestations of a demodekoz

     The main manifestation of a demodekoz are inflammations of the skin of the person. And, if usual antiacne cosmetics does not bring effect, and instead the quantity of pink eels, spots increases, increases a salootdeleniye, complexion becomes unhealthy (from gray to crimson shades), then it is necessary to conduct a microscopic research on contents of hair follicles.

    Clinical manifestations of a demodekoz depend on quantity of actively breeding individuals, on the general condition of an organism and on skin type, in development of symptomatology also the wrong care of face skin is of great importance. There is a classification of a demodekoz, depending on type of rashes, but most often is shown by various forms of rash. Also the form of a demodekoz speaks about weight of process.

    Eritematozny form of a demodekoz

     It is characterized by face reddening and single rashes, in this case it is necessary to differentiate from a rozatse. Vascular neurosis and accession of bacterial microflora is the reason of a rozatse. Demodekoz can complicate a current of a rozatse, but is not the reason of its emergence.

    Education is possible, they are formed because of overflow of follicles by skin fat which is again infected further. Papules at a demodekoza meet most often. Their size fluctuates from 0,5 to 2 mm. As a result the person is covered with various elements from pink till dark red color.

    Rashes cause to patients discomfort, many try to get rid of them mechanically, and therefore except inflammations it is possible to see the dried-up crusts and cyanotic infiltrative sites. Inflammatory process provokes the excessive growth of epitelialny cages and breaks natural peeling, the skin layer is thickened that creates even more comfortable conditions for progressing of a demodekoz. The activator most actively breeds during the spring and autumn periods, seasonality of a recurrence is connected with it.

    Complications of a demodekoz and its communication with other diseases

        The condition of skin at a demodekoza promotes development of other skin diseases. The symptomatology of a rozatse, simple acne rash and dermatitis becomes brighter too. If it is observed a century, then blefarita and conjunctivitis join.

    Raschesa and constant traumatizing skin because of desire of patients to remove rashes mechanically, can lead to a widespread pustulous infection which unlike a demodekoz, affects various parts of the body.

    One of complications can also call isolation and impossibility to lead a former life because of low-esthetic appearance, in some cases it can lead to psychoses and psychoneurosises. Patients with the diagnosis "" at the anamnesis have chronic diseases of digestive organs, endocrinological violations, and also existence of the centers of a chronic infection.

    Treatment and prevention of a demodekoz

    Demodekoz is a chronic disease with the periods of remissions and aggravations. Completely it is impossible to cure it, but it is possible to reach long and permanent remission when a condition of skin clinically healthy.

    Use of antiparasitic medicines is not always expedient. As features of life cycle of the activator of a demodekoz are that that long courses of antiparasitic therapy are required. And almost only medicines which treatment of a demodekoz is possible are medicines of group of a tinidazol and metronidazole. But to reach the necessary concentration in skin, it is required to accept high dosages that adversely is reflected in a liver and on blood formation function.

    The gel medicines containing metronidazole are quite effective as they thanks to the structure are capable to get into deep layers of skin, do not contain fat in the presence of which the activator of a demodekoz begins to breed more actively, render the cooling and moistening effect. The spirit and radio "talkers" made in a drugstore according to the recipe of the doctor are effective at deep damages of skin demodekozy. Their short-term application is pernicious for the main quantity of parasites. But at prolonged use alcohol and air cause dryness of skin, in response to it production of skin fat increases. And flashes with a new force.

    The most productive treatment of a demodekoz consists in joint therapy from the dermatologist and the dermatocosmetologist. In this case medicamentous medicines influence a demodeks, and cosmetic procedures restore protective functions of skin to that state when skin can independently cope with a parasite. So, favorable impact is made by an electrophoresis with the moisturizing substances when effect of electricity for a while blocks activity of a kleshchik, and the moisturizing medicines get into deep layers of skin, thereby revitalizing it and reducing production of skin fat.

    The microdermabrasion course at a demodekoza in a remission stage when there is not a lot of rashes and inflammations, helps to remove mechanically a skin layer with the greatest localization of pincers. Not hardware face peel is also shown. And the subsequent peeling of a face with fruit acids, acidifying skin, in principle interferes with emergence of inflammations and a recurrence of a demodekoz.

    After full clinical treatment from a demodekoz the course of laser coagulation or photocoagulation of vascular defects as because of long and intensive influence of medicines and difficult cosmetic procedures capillaries in a face extend is recommended, and at times there is a formation of a new capillary grid. Inflow of blood increases, so, also skin temperature increases that provokes production of skin fat, it can serve as the trigger for a recurrence of a demodekoz again. Besides, patients should be examined by the endocrinologist, to reconsider a diet, it is better to pass during treatment to dairy and vegetable food.

    Before an initiation of treatment of a demodekoz it is necessary to get rid of all cosmetics and accessories (a brush for powder, a brush for lipstick) and throughout all treatment to avoid uses of decorative cosmetics. For moistening of skin to use light gels, it is desirable in single packings or in a container with the batcher to prevent hit of kleshchik in a bottle. Daily shift of bed linen and more frequent washing of pillows and blankets with the subsequent proglazhivaniye on both sides as temperature influences are pernicious for the activator of a demodekoz is recommended.

    There is also special medical cosmetics which is widely offered to patients demodekozy everywhere with a guarantee of 100% result, but the confirmed statistical data on its efficiency were not submitted yet by any of the cosmetic companies. Treatment of a demodekoz long because for each patient it is necessary to select the individual scheme.

    Specific prevention of a demodekoz does not exist, but if to observe a diet, it is correct to look after skin, not to use someone else's cosmetics, then the probability to ache demodekozy sharply decreases. Patients who achieved permanent remission in the spring and in the fall in the period of aggravations of a demodekoz should pass to vegetable food, more to show consideration for a condition of skin and to hold preventive events, visiting the dermatocosmetologist.

    Demodekoz - treatment should be carried out only under the supervision of a doctor. Self-treatment is unacceptable!!!
