What is psoriasis and what does it appear?Psoriasis is a non -infectious condition of the skin, resulting in red inflamed plaques and dry scales - the result of too rapidly growth of skin cells.The disease most often affects the skin of the elbows, knees and scalp.
Some people are manifested in a slight form, and the symptoms are virtually absent.Others note serious symptoms, frequent downturns.What is psoriasis where it comes from, why it appears, the reasons for appearance, how they are infected - we try to answer these and other questions on the side of the portal.
Psoriasis is an incurable, long -term (chronic) condition of the skin.The aggravation phase is quickly replaced by repair stages.Many patients note the aggravation of the symptoms for November -white months) and for a hot summer period.Psoriasis affects all ethnic species and both genders.Although psoriasis can appear in people of any ages - from infants to the elderly - most often diagnose the disease during adolescence under 20 years of age.
How old does psoriasis appear?The disease is rare in infants (less than 4% of patients) and may be manifested in children's psoriasis when parents are carriers of the disease.Psoriasis of such young children is often preceded by acute pharynx inflammation, tonsillitis, bronchitis or respiratory tract such as cold, influenza or pneumonia.People with psoriasis have more chances to develop diabetes, hyperlipidemia and heart disease.
Why does psoriasis occur?The causes of psoriasis are unknown at the end, but the disease is usually related to the problem of the immune system.What and how does psoriasis appear?The key element is a special type of lymphocytes, so-called T-lymphocytes or T cells.As a general rule, these white blood cells move throughout the body to detect and eliminate foreign substances such as viruses or parasites (streptococcus).However, in patients with psoriasis, T-lymphocytes mistakenly attack healthy skin cells (to combat false infection).
Hyperactive lymphocytes trigger immune reactions, including growth and growth of blood vessels around the papules and pasrias pustulas.These changes lead to an increase in the production of healthy skin cells and other white blood cells.This causes an ongoing cycle against which the new skin cells move too fast on the upper layers of the epidermis - in a few days.
Researchers also found genes related to psoriasis, proving that the disease is inherited, but environmental external factors (physical, chemical, heat effect on the skin) and internal (stress, unbalanced nutrition, sun damage and sleep, infection, alcohol over/regular use).
Signs and symptoms
Psoriasis is manifested in the form of red or pink scaly cones, which are combined into the large papules of the skin.Occasionally, when these small, dry white scales are combed, slight bleeding occurs.
There are many psoriasis - non -pustular (affecting large areas of the skin) and pustular (rarer form, usually on the hands or feet).The rash can be of various outlines and shapes, from points and rocky to a monetary-visible.
The first signs of psoriasis are increased fatigue, weakness throughout the body, sometimes slight dizziness, general malaise.As the rashes develop and increase, symptoms such as itching, burning, pain, sometimes fever, chills.
Stage
In the absence of treatment, psoriasis develops quite rapidly.In the initial stages, a small pink or reddish scales appear on the skin (which are usually placed symmetrically, for example, the spots on both hands are the same).In addition, a scaly surface layer develops at the top of the reddish spots.
This is keratinized skin that can be easily removed independently.After the scales are formed, reddish spots gather in large red plaques, accompanied by severe itching and burning and peeling of the skin.
Aggravation
The aggravation stage is characterized by the occurrence of large (often swollen) spots on the skin (plaque, father), severe itching, burning, often pain.The area of the disease also increases significantly (plaques in diameter is more than 10 cm).A specific feeling of squeezing the skin appears.When you move the disease into the aggravation phase, contact a specialist immediately.At this stage, cracks appear on the skin (due to tightness, dryness and keratinization).
The danger of life
During the aggravation phase, the keratinized dry areas crack, the skin bleeds and becomes more prone to infections, causing the appearance of new plaques (cuber syndrome).
The most serious consequence of aggravation can be psoriatic arthritis (the disease can spread to bones and joints and cause inflammation and deformation) or psoriatic erythroderma (a very serious incurable skin disease that can lead to death).
Psoriasis remains one of the most complex skin diseases.This is illustrated by the procedures available for the treatment of psoriasis.It is very important to take measures to withhold the disease and to prevent it from going to the aggravation phase
