There are three main groups of causes of psoriasis:
Heredity - the leading factor in the development of psoriasis.This is confirmed by the study of dermatosis occurring in twins with relatives for several generations, and biochemical studies of healthy family members.If one parent is sick, chances are that the child is sick with psoriasis, 25% if both the sick - is 60-75%.With this type of inheritance remains unclear and is recognized multifactorial.
to environmental factors include seasonal changes, the contact with the skin clothing, the impact on the psyche of the child's stress, peer relationships.Focusing in a group of children on the sick child, the relationship as a "black sheep", limiting contacts for fear of contracting - all of these factors can provoke new exacerbations, increase the area of skin lesions.Especially vulnerable psyche of the child at puberty, due to hormonal changes.Therefore, a large percentage of detection of the disease accounts for teens.
ratio of genetic and environmental factors causing the occurrence of psoriasis, 65% and 35%.
infections trigger an infectious-allergic response mechanisms that can trigger the development of psoriasis.Thus, the disease may occur after suffering flu, pneumonia, pyelonephritis, hepatitis.There are even a post-infectious form of the disease.It is characterized by abundant papular rash in the form of drops throughout the body.
In some cases of psoriasis precede the skin injuries.
Psoriasis is characterized by the appearance of the skin rash in the form of islands ("patches") red with silver-white patches that are easy to peel and itch.The appearance of cracks on the plaques may be accompanied by slight bleeding and is fraught with the addition of a secondary infection.

advanced stage characterized by the formation of small itchy papules surrounded by red rim.Can grow and thicken the lymph nodes, especially in severe forms of psoriasis.In the stationary stage of growth stops rashes, plaques center flattened, reduced flaking.At the stage of regression elements rash dissolve, leaving a depigmented ring (bezel Voronov).Eruptions leave behind a hyper- or hypopigmented spots.
Localization psoriatic lesions may be different.Most often affects the skin elbows, knees, buttocks, navel, scalp.Every third child with psoriasis struck nails (called a symptom of a thimble, in which the nail plate appear on small holes, pits resembling a thimble).Often plaques found in skin folds.Also affects the mucous membranes, especially the tongue, and the rash may change the location and shape ("geographic tongue").The skin of the palms and plantar surface of the foot is characterized by hyperkeratosis (thickening of the top layer of the epidermis).The person affected less often rash appears on the forehead and cheeks and may spread to the ears.
In the blood test detected an increase in the amount of total protein and gamma globulin levels, decreased albumin-globulin ratio, reveal violations of fat metabolism.
most common form - guttate psoriasis .Manifested in the form of red bumps on the body and limbs that occur after minor injuries, and after infection (otitis, rhinopharyngitis, influenza, etc.).The throat swab cytology detected streptococci.Teardrop-shaped psoriasis is often confused with allergic reactions.
plaque psoriasis is characterized by red rashes with clear boundaries and a thick layer of white flakes.
pustular or pustular shape the disease is rare.The appearance of pustules can be triggered by infection, vaccination, use of certain medications, stress.Pustular psoriasis, occurring in infants, called neonatal.
When erythrodermic psoriasis baby's skin looks completely red;in some areas of the skin may be plaque.Often skin manifestations accompanied by fever and joint pain.
Pustular and erythrodermic psoriasis can be generalized to take shape with a severe course.They require in-patient treatment to prevent death.
Psoriasis babies still known as the diaper psoriasis.It is difficult to diagnose, because the skin lesions occur most often in the buttocks and can be mistaken for symptoms of dermatosis due to skin irritation urine and feces.
Psoriatic arthritis affects about 10% of children suffering from psoriasis.Joints swell, muscles become rigid, there are pains in the toes, in the ankle, knee, wrist joints.Often joins conjunctivitis.
Usually for any form of the disease is changing every three months.In the summer due to solar insolation symptoms often subside.
