- the lack in the body of micronutrients and vitamins.
The symptoms of psoriasis of the stages of the
The disease can be in 4 stages:- initial (early);
- the progression;
- fixed;
- the regression.
The symptoms of psoriasis initial of the first stage. The main signs of the disease at an early stage to go with the appearance of epidermalibus rash papular. After 2-3 days in form of silvery-white scales, easily removed (in the photo). Initial, symptoms is classified as the development of a "map" of the psoriasis.
The stage of progression. This stage is characterized by a strong growth and the follow-up of the mixture of the eruption is papular. The main signs of progression are manifested characteristic flaking, present in the central part of the element, without affecting peripheral crown.
Secondary signs of progression characterized by the presence of a symptom Kebnera (isomorphic peripheral of the reaction). When trauma papular field through 6 to 8 days (according to the form of that trauma) occurs, an element of the psoriasis. In addition, the phenomenon of the Kebnera may occur if any of the psoriatic elements elicit strong scalpendi in the hands, in the area of the elbows, feet, face.
The progressive stage is accompanied by itching and painful and is not repeated for the rest of the stages. As a general rule, the progression may take 2 to 3 weeks and up to 3 (or more) months. During the progression stage, it is recommended that the prophylaxis of reception, and hormone therapy outside of the media.
The stationary phase. This stage comes to replace the progressive and does not have defined time limits. She is able to gently will spend in the regression, the final form of a disease, but is able to progress and following. The symptoms of the stationary phase of psoriasis is applied to the suspension of growth of the platelets and the prevention of the emergence of a new rash papular on the face, the hands, in the field of elbows, etc

In this case, we observe a strengthening of the peeling, the 50% of patients occurs psevdoatrofiya, are classified as the corolla of Voronov. In the peripheral occurs papules angustus band of clear skin, reminiscent of the tegimentum the role of emboquillado.
The regression phase. This step closes the process of inflammation with the typical decrease of the peeling, aequandi the central part of the psoriatic elements with its further resolution (in the photo). psoriatic elements can be of different shapes (rings, the trapeze, the arch, etc) and are classified as "geographical of psoriasis".
There is another option regressus stage of the disease, when the resolution begins with the circumference of the part of the papules, without forming scar tissue, and in the absence of atrophic processes. In that part of the body, where it is observed the papules may appearance of hyperpigmentation. It should be noted that this division of the disease of the options is conditional. Often regressus stage is defined by the method of observation of the sintomatologa clinic of the patient.
The symptoms of psoriasis depends on its shape
Currently, there are a multitude of psoriatic forms that differ in external features and the severity of the symptoms.
The following are the most common forms of psoriasis:
- seborrheic scalp psoriasis;
- vulgar;
- longus;
- rheumatoid arthritis psoriatic
- exudative
- guttate;
- TABULA
- of the nail;
- pustular;
- erythroderma.
Common forms of the disease are TABULATED and psoriasis vulgaris. It should be noted that, in any form of the disease is redness and itching on the skin.
TABULA PSORIASIS. This type of disease develops quickly, sometimes by the nerves soil and flows with the acute sintomatologa. Disease starts with the appearance of a small amount scaly papules, which are clearly limited and slightly above the surface (in the photo). In the future, the papules may join together, forming plaques.
<4_img></4_img>This type of psoriasis can affect large areas of the skin, causing an uncomfortable state of the patient. The trauma of platelets is possible to develop fungal and bacterial infections. Clarification of diagnosis of the disease is done with the aid of confirmation "psoriatic triad".
VULGAR FORM OF PSORIASIS. This type of psoriasis accompanied by active papular and genus TABULA, flaking of the scalp, back, hands, elbows, feet. The eruption from the deck of the silver-white fluffy statera willful and has a clear red (pink) of the border (in the photo). In the diagnosis of the skin reveals positive signs "psoriatic triad".
Rashes appear in places on the elbows, scalp, etc) over 1-2 weeks. This rash is called "guardian" or "guard post". In a category of patients papules become erythroderma. Very rarely vulgar way is manifest on the face and in the genital area.
SEBORRHEIC PSORIASIS. This type of disease is localized in the scalp and is characterized by a strong peeling of the head, the ears and the forehead. This symptomatology is called "psoriatic crown" (in the photo). In the future of the crust crack, and the sick areas of the skin (especially in children) very rursus and looking forward to the delivery of a huge discomfort to the patient. As a general rule, the disease is a seasonal development, it is sometimes possible to its appearance in connection with the increase of nerve excitability of the patient. In case of violation of the immune system is possible the appearance of a fungal infection, which worsens the disease.
The diagnosis of the disease makes it difficult because seborrheic psoriasis is similar to seborrhea of symptoms di i, however, when seborrheic psoriasis there is hair loss. Palpation (feeling) seborrhoeic psoriasis are set forth clearly the boundaries of plates, and seborrheic dermatitis has no such limits.
MULTIFORM FORM. This type of disease develops in patients with disorders of the endocrine system (diabetes, obesity). Exudative psoriasis often seen in older people, it's possible refusal of the child's symptoms.
The main symptom of this type of psoriasis is the absence of white flakes plate papules. Instead, the rash can be covered with yellow-brown crustae that the caused by the excess emission of exudate (inflammatory liquid). He wraps the scales of the eruption. When you remove this bark is stripped erosive the surface moist. Typical papules to psoriasis does not exist, and appears edematous sore part of the body without borders.
With more frequency of the precipitation are found in the folds of the skin (genitals, the area of the armpits, under the breasts), the flexure of the surface in feet and hands. If the patient is held by the varicose disease, the symptoms of the exudative psoriasis of the lower extremities are intensified.
THE NAIL PSORIASIS. This type of psoriasis is characterized by the defeat of clavus plates in the form of maps of cavities, entitled "the symptom of a thimble". The nail becomes dull, the outer edge of the affected nail gets a lot of hem. With this, it is observed friability okolonogtevogo roller and the alteration of the structure of the nail. It should be noted, that the same symptoms are observed during the development of onychomycosis, therefore, requires the completion of a detailed diagnosis.
