Streptodermiya is the infectious diseases of skin caused by streptococcal microflora, activity of microorganisms is followed by education on skin of the purulent shelled elements of rounded shape. The size of the centers of a streptodermiya varies from several millimeters to tens of centimeters in the diameter. The diagnosis of a streptodermiya confirms detection of streptococci in scrape from an affected area of integuments, and also data of bacteriological crops. Treatment of a streptodermiya can include the local therapy, UFOK, local UF-radiation, vitamin therapy, actions directed to immunity strengthening.

Ways of infection with a streptodermiya
Infection happens in the contact and household way, through direct contact to the infected person or through public objects. Flashes of a streptodermiya are observed especially often in the closed children's collectives and kindergartens as children contact with each other, have the general toys. Non-compliance with sanitary and hygienic norms sometimes leads to the fact that practically all children in establishment can be infected with a streptodermiya. Infection of adults occurs in the contact way, is more often from sick children, or through the objects, general with the child.
Clinical manifestations of a streptodermiya
The incubatory period at damages of skin a streptococcal infection makes 7-10 days then on skin there are roundish pink spots which can have the wrong outlines. In several days of a spot gradually regenerate in gnoynopuzyrkovy elements. Depending on depth of damage of skin divide two forms of a streptodermiya; at streptococcal impetigo purulent bubbles are opened quickly and after healing there is no cosmetic defect left and scars, at an ordinary ektima which is considered a deep form of a streptodermiya, the rostkovy layer of skin is surprised that it can lead to scars. At a sharp superficial streptodermiya after recovery temporary hypopigmentation of skin is observed.
Subjective feelings are practically absent. Some patients show complaints to an insignificant itch and dryness of skin of affected areas. At extensive defeats by a streptodermiya at children and in the presence of a serious illness, rise in temperature to subfebrilny and increase in regionarny lymph nodes can be noted.
At a deep form of a streptodermiya large ulcer elements with a dense crust after which healing on skin there are well noticeable hems are formed. More often the lower extremities are surprised though process can extend on all body. If infectious process accepts diffusion character, then the streptodermiya centers quickly extend on a body, merging with each other. The Intertriginozny form of a streptodermiya differs in the fact that skin folds generally are surprised, and process does not go beyond their limits. The streptococcal infection affects both healthy skin, and skin on which there are already any diseases, but skin appendages – nails and hair are never involved in process and their state does not change.
Overcoolings and overheat, existence of a varicosity, decrease in local immunity and the lowered reactivity of an organism, existence of open wound surfaces and constant travmatization of skin lead to synchronization of a streptodermiya. Chronic forms of a streptodermiya often meet against the background of diabetes, a renal failure and at other chronic pathologies, the disease accepts wavy character, between a recurrence on the place of purulent bubbles the peeling centers are formed.
Clinically chronic streptodermiya is shown by existence of the big centers of defeat to 10 cm in the diameter with uneven scalloped edges and the exfoliating horn layer of epidermis on the periphery. After opening of purulent bubbles are formed it is purulent - serous crusts of yellowish-brown color. If to remove crusts, then the bright pink erosive surface is bared. At a long and long current of a streptodermiya because of increase in sensitivity to microorganisms there is a regeneration of streptococcal defeats in microbic eczema.
Initially the streptodermiya has the localized character, but neglect rules of personal hygiene, lack of adequate treatment and contact of affected areas with water promote spread of an infection. Especially distinctly it can be observed at patients with a streptodermiya of children when when washing the child with damages of face skin, in several hours of a spot considerably increase in sizes and on border with healthy skin hypostasis is observed.
Any violations of local blood circulation and imbalance in a skin metabolism promote increase in sensitivity of skin to pathogenic agents and can provoke a streptodermiya.
Diagnostics of a streptodermiya
Existence of a clinical picture, characteristic of a streptodermiya, and stay in the center of defeat are the main criteria of diagnostics. For confirmation of the diagnosis resort to a microscopic research and bacteriological crops of scrape. In the material taken at scrape find streptococci. The microscopic research needs to be conducted prior to therapy. If the patient carried out self-treatment by antibacterial ointments, then at microscopy the diagnosis can not be confirmed. In this case the streptodermiya is diagnosed on existence of clinical manifestations.
Streptodermy needs to differentiate with a small tortoiseshell, otrubevidny it is deprived, piodermiya, atopic dermatitis and eczema. For this purpose also detailed poll of patients is necessary to exclude contacts with allergens. It is necessary to exclude or confirm existence of fungi at a scrape research on mushrooms and to carry out additional diagnostics for an eczema exception.
Treatment of a streptodermiya
If the centers of a streptodermiya have single character and the general state does not suffer, and also at treatment of children with the normal immune status - rather local therapy. In all other cases besides local medicines appoint vitamin therapy, the all-strengthening medicines, haemo therapy, ultra-violet radiation of blood (UFOK) and medical UF-radiation to sites of the skin affected with a streptodermiya.
For treatment of a streptodermiya it is necessary to exclude contacts with water, instead healthy skin is wiped with a tampon the moistened water or infusion of a camomile. Warm clothes, synthetic fabrics can cause the increased sweating therefore it is necessary to observe temperature condition indoors and to wear clothes from natural fabrics.
Children sick with streptodermiya are isolated and appoint a quarantine for contact persons to 10 days (term of the incubatory period). The hypoallergenic diet with an exception sharp, fat and sweet reduces an allergic state, the ekssudation thereby decreases and the skin affected with a streptodermiya begins to dry up.
Make processing of skin in the defeat centers. Bubbles and pustula accurately open at the basis with sterile needles and twice a day process aniline dyes (diamond greens, a methylene blue, etc.) then the dry aseptic bandage with disinfecting ointments is applied the centers of defeat. Crusts which are often formed at a streptodermiya grease with salicylic vaseline, and in 12-20 hours they without serious consequences act.
If the centers of a streptodermiya are localized on a face, then can be observed is long not healing zayeda which it is necessary to grease 1-2% with nitrate silver. At long slow streptodermiya reception of antibacterial medicines for a period of 5-6 days is shown. Norsulfazol and sulfanylamide medicines render good therapeutic effect.
Prevention of a streptodermiya is maintaining a healthy lifestyle, the balanced food and stimulation of immune system as healthy skin is inaccessible for introduction of microorganisms.
