What is psoriasis?

What is psoriasis The basis of Psoriasis is:
  • excessive multiplication of cells;
  • A violation of the keratinocytes;
  • The emergence of the inflammatory infiltrate in the Dermis.
Speaking of chronic character, it must be emphasized that, if a young man is a tiny Plaque appeared and soon disappeared, which means that in 20 years he can look back on new tiles. Psoriasis "slumbers", but not cured, and his behavior is reminiscent of the man who cured many years ago from alcoholism, but, for obvious reasons, avoid any alcohol because after 30 years of sobriety you get in the fight.

Causes of psoriasis

Causes of psoriasis The incidence of Psoriasis is very high: even in the successful countries of Western Europe, he meets 2% of the population. To start, the disease may at any age, but the debut often occurs at a young age, and only in 1/3 of patients it occurs after 40 years. It is believed that the presence of relatives with Psoriasis significantly increases the risk of its occurrence, and there is an autosomal – dominant mode of transmission of the genetic defect (i.e., not grounded). But most of the time the causes of Psoriasis are the effects of a number of negative factors that contribute to the restructuring of the body. We list the most important causes of psoriasis:

What happens in the skin, or pathogenesis of Psoriasis the pathogenesis of Psoriasis "Unit" Psoriasis is Plaque cutaneous, flows in Immune inflammatio, as well as in the joints in psoriaticheskom Arthritis. In blayshkah many substances, such as analogues discovered leukotrienes, which is a hotbed of leukocytes inflammatio. As a result of the interaction of keratinocytes with immunokompetentnymi cells, a Zone inflammatio occurs, with the release of mediators of inflammatio. In psoriaticheskih blayshkah, and in the synovial fluid in psoriaticheskom Arthritis presence of TNF-Alpha or Tumor necrosis factor. The Tumor itself has nothing to do with it — this is the title of historical. It is known that TNF plays an active role in various chronic inflammatio.
In the skin, various inflammatory changes, leading to the emergence of highly characteristic for the Psoriasis characteristics: spots, Terminal triad-foil, and a bloody dew.

Stages of Psoriasis exacerbation, stability, and Regression

All the worries and grief, falls on the progression of the disease, when the symptoms escalated. For each patient, an exacerbation bears an individual character. Sometimes aggravation occurs in response to the "good deeds". For example, a Patient smoked for several years. The decision that Smoking is a detrimental effect on the course of Psoriasis (and rightly so), he throws it, but after a month added to 5-8 kg. per a result of a significant aggravation to the increase in the weight and "ignored" the fact that a successful fight against Smoking. Aggravation In spite of the "special way", there are some common signs:
  • Aggravation appears after a cold, sore throat, Stress, Binge;
  • The emergence of new patches occurs;
  • On old stains extended peripheral area, patch "to grow";
  • Thickens the layer of scales;

On blayshkah stops the growth, formed "psevdoartoficheskyi" bezel, the disappearance and re-aggravation. Step back Mostly the improvement starts with the middle of the plate. The disappearance of the shed, starts the new skin appears. The Zone of the peripheral growth continues to be pale and inactive, in consequence of the "garlands" of the rings, and all sorts of whimsical spots. If the rash is completely gone, often occurs at this point on the area of the skin with decreased pigmentation. Very often step back psoriaticheskih rash develops in the summer, if the Patient happens in the sun. Deterioration, on the contrary, in spring and in autumn, when the skin suffers from a lack of sun.
  • In the case of the incomplete Regression of the lesions usually the "duty Plaques" that are in the area of the elbows and on the knees.
