Impetigo is a superficial bacterial skin infection, caused by a streptococcus (Streptococcus pyogenes) and / or a staph (Staphylococcus aureus). It is a disease and not immunizing autoinoculable. Contrary to popular belief, impetigo does not arise due to poor hygiene.
It is contagious with small family outbreaks or communities that justify the quarantine. Impetigo in adults almost always testifies of pre-existing skin lesions, especially a ectoparasitose, because the bacteria get into the skin through the various lesions. We can see the show for impetigo in various skin diseases (such as eczema, scabies or lice), or simply as a result of scratches and insect bites.
The elementary lesions cause an eruption of vesicles or translucent bubbles, after a few hours, become confused and become pustules that burst, releasing their contents form a yellowish crust on drying. These scabs are called ".
Impetigo appears especially in the face, particularly around the edge of the nose and mouth due to the presence of the bacteria at this level. However, it may appear on other body parts like the scalp, arms and legs due to the porting guide.
In principle, once gone, lesions leave no scar (except in rare cases).
This is the characteristic shape observed in the newborn. It has a bacterial (staph). The bubbles can be large and be surrounded by a diffuse erythema. The lesions that lead to scabs dry and fall quickly.
Made of confluent vesicles in layers. Impetigo dry vine rereading of small plates made of rim polycyclic confluent vesicles.
Also known as toxic epidermal necrolysis, or scalded skin syndrome. It appears during systemic infections (General) by strains of Staphylococcus aureus secretes toxins destroying specific desmosomes, the exfoliatines. It is characterized by detachment and destruction of the epidermis in multiple locations (shreds). It is accompanied by significant impairment of general condition with fever and dehydration.
This is a painful form of burrowing called impetigo. It usually locates in the lower limbs. This form is found most commonly in fragile subjects such as alcoholics, diabetics, immunosuppressed, malnourished subjects and poor hygiene. Ecthyma begins as an ordinary impetigo as a bubble or pustule. The crust that replaces the pustule is very broad, rounded, blackish, measuring 10 to 20 mm in diameter. Ecthyma can be the starting point of a real leg ulcer and take a look extensive.
She rapidly improved. Very rarely impetigo may be the front door of a severe systemic infections with streptococcus or staphylococcus.
Local treatment may be sufficient in form very small areas, it consists in the softening of the crust by spraying water over Dalibour and applying:
It is most often prescribed. A systemic therapy may be necessary if the lesions are too large or if satisfied that the local treatment will be applied correctly is not absolute. But if not very extensive lesions (
