Streptodermia


Streptodermia-streptococcal

Streptodermia or streptococcal pyoderma is an infectious skin disease that develops as a result of the introduction into it of pathogens, streptococci. In this case, the most important is beta – hemolytic Streptococcus group A. it is Known that this microorganism is pathogenic not only for the skin. During its impact on the human body often affects the heart and kidneys, and developing various autoimmune diseases and allergic dermatitis.

Causes of streptococcal

The skin of a healthy person performs a good barrier function of penetration into the body of various pathogenic agents. However, when exposed to the human body of various factors external and internal environment, this protective effect is greatly reduced. This should involve contamination of the skin, and disturbed local blood circulation (varicose veins), and local impact high and low temperatures. Different microtrauma of the skin also contribute to the penetration of pathogenic organisms into the skin. It and abrasions, and bites, and scratches, and abrasions. The decrease of immune protection as a result of chronic diseases and intoxications, fatigue, stress, starvation and weight are confounding factors for the occurrence of streptococcal impetigo.

Symptoms of streptococcal impetigo

Symptoms and causes of streptococcalThe most common manifestation of streptococcal impetigo is a impetigo. This most often affects thin and fragile skin of the face (around the nose and mouth ) or open skin other areas of the body (hands, feet, shins) in children and women. Impetigo is characterized by sudden onset. On the background of reddened skin appears a bubble the size of a pea, filled with turbid yellowish contents. This bubble very quickly increases in size, up to 1-2 cm, then opened, exposing the erosive surface with bits of epidermis on the periphery. Almost instantly in the drying up of this element to form honey-yellow crusts. The metamorphosis of these elements is accompanied by intolerable itching. Scratching contribute to the rapid infection of healthy skin areas and spread of process on the periphery, where they form such new elements of the rash. Thus formed extensive lesions. One of the additional factors of infection are household items ( towel, pillow case, etc.). In this case, there are multiple infected areas of the skin, unrelated geographically. So the picture of classic impetigo.

In recent years, increasingly began to appear, especially the development of bubbles. When the cystic form of impetigo appear rash elements-bubbles with tighter lid. Such an element has no tendency to peripheral growth and autopsy. At this skin hand and body marked with numerous small bubbles with serous-purulent contents. These bubbles with a tight lid and often striking okolonogtevoy roller. Outwardly, it looks like bubble the shape of a horseshoe with the respective content. This form of lesion the skin Streptococcus is called turnil. You can often see bubbles of large size, dries in the center and at the periphery surrounded by rolling, containing sero-purulent contents.

Most often, when impetigo patients worried about itching and dryness of the affected areas. Sometimes, children with extensive skin lesions and the presence of comorbidities may be fever and swollen lymph nodes close to the lesions.

With the recovery in place of impetigo there remains no cosmetic defects and scars, in addition to post-inflammatory hyperpigmentation.

Streptococcus can also affect the deeper layers of the skin. This so-called streptococcal ecthyma, in which the abscess occurs with serous-purulent contents not riddled with hair that has a tendency to peripheral growth and rapidly increasing in size. This item is soon shrinking in the crust of greenish-yellow colour, which, unlike impetiginoznoy sits tightly on the skin. When rejection crusts exposed this painful ulcer, with uneven edges and purulent discharge. Because ecthyma affects the malpighian layer of the skin, the healing of such element causes the formation of a visible scar. The most frequently ecthyma is located on the lower limbs.

Diagnosis of streptococcal

Due to the fact that the streptoderma is an acute lesion of the skin and tends to a rapid expansion, with the appearance of symptoms such as bladder and itching should immediately consult the doctor. In this case, to confirm the diagnosis will be assigned and mycological microscopic studies of skin flakes. It is clear that self-medication is unacceptable, because when using antibacterial ointments diagnosis may not be confirmed.

Treatment streptococcal

To exclude peripheral spread of the skin around the lesion is wiped with a disinfectant solution (boric or salicylic alcohol) at each change of dressings, namely 2 times a day.

At the initial stage of the pathological process, in the presence of bubbles and erosions on a background of reddened skin it is necessary to conduct outdoor treatments. Quick and positive effect wet-drying bandages with different aqueous solutions (1-2% resorcinol, 0, 25% silver nitrate). The therapeutic effect depends on technology perform such procedures. Sterile gauze cloth, from 6-8 layers soaked in a treatment solution at room temperature, is extracted and superimposed on the damaged surface of the skin. After 15 minutes, the same to be re-wetted cloth in the prepared solution, and pressed again covering the area of streptococcal impetigo. Thus within one and a half hours is carrying out manipulations with wet-drying bandages. During the first days of treatment of streptococcal wet-drying bandage, thus conducted, should be repeated 2 to 3 times, with breaks of 3 hours.

Treatment streptococcalCracks at the corners of his mouth – binding, should be lubricated 1-2% silver nitrate 2 to 3 times a day.

Tyre bubbles should be opened with observance of all rules of aseptics. In the subsequent processed bubbles overlap bandage with antibiotic ointment, such as tetracycline eye ointment or streptocidal ointment, 12 hours, 2 times a day. On peel also requires the use of ointments with disinfectants:3% rivanol, ethacridine-boric-naphthalan and erythromycin ointment.

With strong and unbearable itching, for the exclusion of active infection are appointed by antihistamines, such as claritin, “Telfast”, in standard therapeutic doses. In the same vein, children daily cuticles nails alcoholic solution of iodine.

In marked inflammation at the periphery of the hearth, short-term use of hormonal external means (“Triderm”, “Lorinden A, C”). It must be remembered that prolonged use of these funds, there are irreversible changes in the skin in the form of thinning. In this regard, hormonal and external means should not be used without the supervision of a physician.

During the widespread nature of the process, with increasing temperature and the increase of regional lymph nodes inside antibiotics (semisynthetic penicillins or cephalosporins).

In protracted and sluggish process justified the appointment of vitamin (A, B1, B6, C, R) and immunostimulating therapy (autohemotherapy and appointment of pyrogenal courses).

After removing the acute inflammatory phenomena is assigned to a course of ultraviolet irradiation suberythermal doses to the affected areas of skin.

When the external treatment of stratagemmi has been proven the use of folk remedies.

Self-treatment of streptococcal

To create a drying effect on the skin recommended use of decoctions of various herbs in the form of wet-drying dressings. To exclude the possibility of additional sensitization of the skin is a preference for the least allergenic herbs such as oak bark or chamomile.

For the entire period of treatment of streptococcal prohibited the use of hygienic bath & shower. Instead, healthy skin is wiped with a cloth soaked in chamomile tea.

Diet with the exception of sharp, fatty and sweet reduces allergic mood of an organism, which reduces the exudation (soak the wound), thereby contributing to the drying hearth.

Complications of streptococcal impetigo

When the allergic disposition of the patient and, if wrong and untimely treatment conducted streptococcal lesion may lead to increased sensitivity of the skin to microbes and thus cause more difficult to treat the disease is microbial eczema. On accession to the basic process of eczema can be judged by the appearance of reddened background microarray, which are separated drops of serous fluid.

Prevention of streptococcal

Preschool children with streptoderma isolate and prescribe quarantine for 10 days.

Healthy lifestyle, balanced diet and regular hygienic care of conditions are good for the skin immunity to streptococcal disease.

Consult a dermatologist on the subject of streptoderma:

1. Streptoderma and pyoderma are one and the same?
No, not really. Pyoderma is a skin lesions as a result of the introduction into it of any pathogenic peacocke. Most often it is the Staphylococcus and Streptococcus. Depending on the type of microorganism diseases are named: streptoderma and stafilodermia, and pyoderma is a common name for pustular skin diseases.

2. Possible without making any tests to determine which pathogens caused the skin lesions?
to Determine without testing, of course, impossible, but we can assume. For example, it is known that streptococci cause surface serous exudative nature of the lesion, not penetrating the skin appendages (hair follicles, sebaceous and sweat glands). Such lesions are prone to peripheral growth, often is in the folds and is accompanied by severe itching.

3. Why in kindergartens upon detection of streptococcal imposed quarantine?
In children malformed immunity, so the outbreak of streptococcal impetigo in such groups arise very quickly. The reason for this is the close contact of young children with each other, with the same toys.

4. How many days should pass from the moment of infection until the first appearances of the elements?
In medicine this period is called incubation and streptococcal lasts about 10 days.

5. How can a grown man get infected from a child?
Of course, this infection is possible through close contact with infected skin or through children in common with the child objects.

6.  I heard somewhere that the cracks in the corners of the mouth is often caused by Streptococcus. Is that also a streptoderma?
Such cracks are called Zayed and actually it is – erosion, surrounded by a collar of the stratum corneum, remaining after the autopsy bubbles and surrounded with honey-yellow crusts. Most often it is the lesion of the skin caused by Streptococcus, and constant licking of the lips and increased salivation leads to the development of maceration (swelling of the skin caused by the soaking liquid), thereby reducing the barrier properties of the skin and reproduce it this pathogenic organism. In this case, the aggravating factor is the deficiency of vitamin B2 deficiency Riboflavin. With regards to increased salivation, most often it is the result of teething in children, the wearing of dentures in adults, as well as a sign of worm infestation, which is necessary to perform additional tests.

7. Why fat people are prone to streptococcal skin folds?
It is known that such a process is most often localized in the groin, buttock, armpits, behind folds and under the Breasts. This contributes to increased sweat and sebum secretion, the release of the sugar with then that violates the integrity of the skin and contributes to the development of Streptococcus.

8. my daughter around her nose, after the rejection of the peel is yellow, left pigmented spot with a bluish tinge. Now, this spot will be on her face always?
Hyperpigmented spots after strep skin lesions remain a short time and then fade.

9. What is white versicolor of the face?
This is one of the forms of streptococcal impetigo, which manifests itself melkootrubevidnoe peeling, on a background of red and pink spots. Often occurs in children and in individuals a long time being in the open air and sun. Contributes to the development of this process hypovitaminosis of vitamin A – retinol.
