Dermatology - diseases of the skin


Impetigo – a skin disease characterized by lesions of its surface layers. The primary form of infection (at the slightest damage to the skin) most often occur in children, secondary (compared to other dermatosis characterized by pruritus) – in adults. Earlier this pathology along with ecthyma called streptoderma. But now it is very common to see this diagnosis.

Causes of impetigo

The main causative agents of this disease are staphylococci or streptococci of group A, or a combination. Predisposing factors for impetigo are: high temperature and humidity, not personal hygiene, decreased immunity, minor injuries, diabetes, a blood disorder, as in obliterating diseases of the lower extremities, itchy dermatitis, treatment with antibiotics. Very often when prescribing or incorrect prescription of hormonal ointments for other skin diseases, “say thank you” pathogens gnojnica skin diseases, in our case of impetigo. Due to hormones everything is growing and developing perfectly. By the way, the disease is very contagious, if it is in the children’s team, even be necessary in the sanitary – hygienic actions.

Symptoms of impetigo

To Distinguish impetigo staphylococcal and streptococcal.

The Streptococcal impetigo begins with the formation of low-lying, prone to peripheral growth of conflicts – cavity elements such as bubbles ranging in size from 2 to 10 mm and more in diameter. Rashes scattered or crowded groups, surrounded by a narrow rim of hyperemia. The contents of the conflict at first transparent, becomes cloudy and then quickly shrinking in light yellow peel, is eliminated after 5-7 days, after which the remains depigmentation.

Causes of impetigoThe varieties of streptococcal impetigo is simple versicolor face or dry pyoderma – foci melkoplastinchatym peeling with slight reddening of the skin.

Another type of streptococcal impetigo – streptococcal binding, which are more common in children. They begin with the appearance in the corner of the mouth bladder with a sluggish thin tires, in its place quickly formed slit-like erosion, after removal of which, found a red wet easily bleeding surface with a crack in the center. After 1-2 hours Zayed road again crusts. The process may be accompanied by small soreness when opening the mouth. The process often extends to the mucous membrane of the mouth. Sometimes impetigo occurs in isolation in the mouth, where conflict quickly opened formed a painful erosion, becoming covered with purulent coating.

A variation of the cystic impetigo is superficial panaritium, which conflicts occur on an arcuate cushion nail around the nail at the site of hangnail injuries (for example, during a manicure), needle sticks, etc. When injury such conflicts is opened and is formed oozing erosion in a large number of streptococci in the discharge.

Staphylococcal impetigo (folliculitis)
Folliculitis is an inflammatory damage of the hair follicle caused by Staphylococcus. Folliculitis may be superficial or deep. Superficial folliculitis is characterized by the formation of multiple small (1-2 mm, some can reach 5 mm) pustules, pierced in the center with hair and surrounded by a narrow pink border. On day 3-4 of their content dries up, there are yellow scabs, which after falling on the skin without leaving marks.

With a deep folliculitis of the skin are formed painful red nodules the size of 5 mm and more in diameter, sometimes with abscess in the middle. After a few days the nodule resolved or suppurate, and then opened. After healing of such a nodule often remains a scar.

Mixed (streptostafilokokkovoe) impetigo
Symptoms of impetigoWith a combination of streptococcal and staphylococcal infection develops mixed (vulgar) impetigo, in which the contents of the conflict is purulent and crusts are massive. When removing the crusts exposed moist from the eroded surface.
Vulgar impetigo is usually on the face and other exposed parts of the skin. Disease tends to the children, adolescents and young women. Without treatment former near or distant lesions on the skin arise the new phlyctenas, the process often takes common. Is set to transfer the infection to new areas through the hands and linen.

Complications impetigo
Most often the disease ends without consequences, but there may be complications. One of the most unpleasant complications are complications on kidneys (nephritis) and the heart (myocarditis).

Staphylococcal impetigo can be complicated by widespread purulent processes – abscesses and phlegmons.

Impetigo Treatment

Impetigo TreatmentImpetigo Treatment is usually performed on an outpatient basis. Affected and adjacent areas of healthy skin cannot be washed water them 2 times a day RUB a 2% salicylic or camphor spirit. Separate phlyctenas opened and treated with alcoholic solution of aniline dyes, fucorcinum, use also disinfectant ointment (erythromycin, heliomycinum, levomicetinom liniment etc) 3-4 times a day without a bandage for 5-10 days until complete epithelialization of erosions. During treatment and then for 1-2 weeks. the affected area is wiped with alcohol. In the case of I. vulgar common in young debilitated children spend antibiotics, the fever and the presence of toxicity is generally in the children’s hospital.
