Streptoderma - a group of skin diseases caused by streptococcus. The pathogenic activity of streptococcal bacteria is accompanied by the appearance of the skin round pink spots of irregular shape. Size streptococcal foci can vary from a few millimeters to a few centimeters in diameter. Outbreaks are localized mainly on the back, face and lower extremities. Streptoderma often affects children and women.
Forms and streptococcal species
There are the following varieties streptoderma: bullous impetigo, strep impetigo (contagious impetigo), slit impetigo (angular stomatitis, Zayed), impetigo nail ridges (turniol), lichen simplex.
According to the degree of destruction of epithelial tissues emit deep and superficial form of streptococcal. Surface form called streptococcal streptococcal impetigo, and a deep common form is called ecthyma. When strep impetigo festering blisters quickly burst, leaving no cosmetic defects.
When ecthyma affects deeper layers of skin. In this form large ulcerated elements coated with a dense shell. After healing of ulcers on the skin are clearly visible scars. In the diffuse type of streptococcal affects extensive areas of the body. When intertriginoznoy type of disease festering pockets are located in the skin folds. The disease affects healthy skin and attached to the current inflammatory process.
Streptoderma transmitted from person to person. The incubation period of the disease lasts about a week. The chronic form of the disease may occur in the redistribution of ulcers and wounds that do not heal for a prolonged period of time. The risk of streptococcal increases for varicose veins, violation of local circulation processes, endocrine disorders, diseases of the gastrointestinal tract as well as in long-term cooling of the extremities, resulting in improvement of skin sensitization to staphylococcal and streptococcal infections.
An important role in the development of the disease plays an imbalance in the skin metabolism. Chronic forms of the disease are common in patients with renal insufficiency, diabetes and other chronic conditions.
The symptoms of streptococcal
Subjective feelings when streptoderma virtually absent. Swollen lymph nodes and fever to subfebrile - common symptoms of streptococcal children. Some patients complain of dry skin and slight itching of affected areas.
When slotted impetigo after opening purulent vesicles formed shallow linear cracks. They periodically covered by yellow crusts that disappear fairly quickly, again exposing cracks in the skin. This form is accompanied by a streptococcal discomfort, burning, itching. Maybe salivation, pain when eating.
When impetigo nail ridges bubbles are localized on the hands, the skin in the area of the nail plate. Development of the disease is usually preceded by trauma to the skin. During the development of the contents of the vial streptoderma changes from serous to purulent. After opening the vial is formed on the skin ulcer or erosion, covering the nail fold. Symptoms of streptococcal species may be general weakness, fever, swollen lymph nodes, asthenia.
Strep diaper rash most commonly affects the inner thighs, the area under the breasts, groin and buttock area. The disease tends to be recurrent or chronic.
Streptoderma in children is most often seen as a simple stripping. The disease spreads rapidly in children's groups. The rise of the incidence observed in the spring and fall. In a simple herpes usually affects the cheeks, legs, oral part of the face. Progression of the disease is accompanied by strong pruritus. Symptoms in children streptoderma reduced or completely disappear after exposure to the sun.
For the treatment of streptococcal besides local drugs usually prescribed restorative drugs, vitamin therapy, therapeutic ultraviolet radiation affected areas, as well as ultraviolet blood irradiation (UBI).
During treatment streptoderma should avoid contact with water. Synthetic fabrics, warm clothing can promote excessive sweating. It is necessary to wear only natural fabrics and observe the temperature conditions in the room. If this disease is very important to stick to hypoallergenic diet with the exception of fatty, spicy and sweet.
When streptoderma children must assign contact persons for quarantine for ten days.
In the lesions produce skin treatment. The pustules and bubbles reveal sterile needles at the base, and then twice a day, the affected skin is treated with aniline dyes. After that applied to the affected areas dry aseptic bandage with disinfectant ointments. Salicylic crust smeared with Vaseline. In the long streptoderma doctor may prescribe antibiotics.
