Pyoderma

PyodermaPYODERMA is a group of diseases of the skin, the main symptom of which is festering. Etiology, pathogenesis. Pathogens - Staphylococcus and Streptococcus spp. In the pathogenesis of an important role of endogenous disorders (diabetes, blood diseases, abnormalities in vitamin metabolism, gastrointestinal disorders, obesity, liver disease, neuropathy, and others), exogenous exposure (minor injuries, scrapes, cooling, overheating, contamination of the skin, malnutrition and other) and long-term treatment with corticosteroids and cytotoxic drugs. On the etiological principle distinguish stphiladelphia and streptoderma, which in turn are divided into superficial and deep. Stphiladelphia. Distinguish the following types of stafilodermy: ostiofollikulit, folliculitis, sycosis, epidemic disease of the newborn (surface stphiladelphia), furuncle, carbuncle and hydradenitis (deep stphiladelphia). Ostiofollikulit is located at the mouth of the hair follicle is a small pustules with a tight lid, from the centre of which stands the hair; on the periphery of the pustule bordered by a narrow rim of hyperemia. When the distribution of festering deep into the follicle ostiofollikulit transformed into folliculitis, which is clinically differs from the first by the presence of infiltration in inflammatory nodule, located around the hair. Osteopathically and folliculitis can be singular and plural. They are localized in any part of the skin where there are long or well developed vellus hair. When the involution is formed purulent crust, apostasy which reveals the bluish-pink spot, eventually disappearing. Staphylococcal sycosis - multiple, dense to bluish-red and infiltrated the skin usually of the chin and upper lip astrophysically and tinea in various stages of evolution and tends to be a long, sometimes many years, recidivisim. Epidemic disease of the newborn - is a highly contagious acute disease that affects infants in the first 7-10 days of life. Characterized by numerous bubbles of various sizes of clear or turbid contents and thin loose tire. Affected the entire skin except the palms and soles. Bubbles part dry to form a thin crusts or continuing to grow, merge with each other and burst, leading to the formation of erosive surfaces, sometimes exciting all the skin (exfoliative dermatitis Ritter). Possible involvement of the mucous membranes. Can join a General phenomenon, sometimes severe, leading to death. Furuncle-purulent-necrotic inflammation of the hair follicle and surrounding tissue; clinically is an acute inflammatory site with pustules on top. At the opening is exposed necrotic rod, the rejection of which is a plague, healing the scar. Subjective pain. Boils can be single or plural, for their acute and chronic. Sometimes join lymphadenitis and lymphangitis, fever. When localization on the face, especially in the nasolabial triangle, possible meningeal complications. Carbuncle - thick deep infiltration crimson red with the phenomena pronounced perifocal edema resulting from a deathly-purulent inflammation of the skin and subcutaneous fat. Through holes formed dense stands pus, mixed with blood. Upon rejection of necrotic masses formed deep ulcer, healing rough scar. Subjective excruciating pain. Overall condition is generally violated. Carbuncles occur in immunocompromised and debilitated individuals on the nape of the neck, back and rump. Extremely dangerous carbuncles person. Hydradenitis - purulent inflammation of the apocrine sweat glands. In the skin (usually axillary hollows formed acute inflammatory site, at the opening of which pus. Subsequently, the process undergoes scarring. Marked tenderness. Possible violations, especially when multiple hidradenitis forming massive conglomerates. Hydradenitis more common in women suffering from sweating. Streptoderma. The basic morphological element streptoderma conflicts is a cavity in the epidermis with thin and flabby tire, filled with serous-purulent or purulent content located on the smooth skin and is not associated with the balances and hair follicle. There are streptococcal impetigo, bullous impetigo and vulgar actimo. Streptococcal impetigo is a contagious disease affecting children and young women. Characterized by a rash flicken, surrounded by rim of hyperemia. Often tire flicken is broken with the formation of superficial erosions pink-red color separating rich exudate. Exudate, and the contents flicken, dries quickly with the formation of a honey-yellow crusts on apostasy being discovered pink spots, soon disappearing. With the progression of flickery be multiple, and can merge in the vast areas covered with massive crusts. Noted mild itching or slight burning. The General condition is usually not disturbed. The process is localized on any area of skin, often on the face, in particular in the corners of the mouth in the form of cracks (Zayed); sometimes conflicts horseshoe covers the nail (okolonogtevogo impetigo). When joining a staphylococcal infection formed amber-yellow pustules quickly podsypaya in thick loose serous-purulent crusts, sometimes mixed with blood - there is vulgar impetigo, particularly those with a high contagiousness, the damage was extensive areas of the skin, the accession of folliculitis, boils, and lymphadenitis.
