Why is psoriasis difficult to cure
The Skin changes (exanthema) are limited in the form of a flock, whereby the individual flocks can be of different sizes. The focal point is red and sharply demarcated from healthy skin - a visual difference to neurodermatitis. In three out of four people affected, whitish to silvery, shiny scales, the so-called plaques, form. Not many scales are visible at the beginning. Rather, the flocks are very red. Usually the skin changes occur symmetrically. In the acute phase, the affected areas itch and burn.
The spots can go away on their own after weeks or months. However, psoriasis is chronic inpatient in around two thirds of those affected. That is, it never disappears entirely. Extensive sides of the extremities such as elbows, knees, sacrum and the hairy head are particularly often affected. Psoriasis foci in these areas usually do not itch, but heal hardly or only very slowly. In principle, however, psoriasis foci can occur on any skin area.
Psoriasis shows very different manifestations. In principle, everyone with the disease has their “own” psoriasis. Spontaneous healing may also occur - but relapses can occur at any time in the course of life. Appearance-free intervals can last from months to years. An improvement or healing in summer (due to the influence of sunlight and bathing) and relapses in winter are typical.
At younger children often only small spots appear on the face or on the flexor sides of the joints. In infancy, the disease can also manifest itself in the diaper area, including the groin area. Then typical care products and treatment methods for diaper rash do not help to improve the clinical picture.
Only at; only when older children The so-called plaques typically show up on the scalp, face and on the extensor sides of the elbows and knees. The scalp is most commonly affected and is often the area where the condition first shows.
The sick children do not always have more or less extensive diseased areas. In approx. 2% of the cases it shows up all over the body teardrop-like clinical picture (psoriasis guttata), which is often observed about 2 weeks after an infection with streptococci or viruses and often heals within 3 to 4 months. Some sufferers later develop plaque psoriasis.
In the case of children, the exanthemic form observed the disease, which also suddenly z. B. occurs after a streptococcal infection. The foci are distributed almost over the entire surface of the skin, are of different sizes, can enlarge and flow into one another. Often the typical dandruff is missing, so that the disease is mistaken for an infection. In contrast to adults, the face is also often affected in children.
There is also the relatively rare one pustular formin which the skin's inflammatory reaction is so severe that pustules form. About 1 to 5% of children are affected. In addition, the clinical picture can affect the Palms and soles (palmoplantar psoriasis) or the skin folds (inverse psoriasis).
The psoriasis can also affect itself Nails (nail psoriasis) and Joints (psoriatic arthritis) demonstrate.
Changes in the nails occur in up to 40% of the sick children. Boys are more often affected than girls. The nail and its subcutaneous tissue are thickened. Oil stains and longitudinal and transverse grooves can also be observed. The nails may be discolored, brittle or even crumbly. They can also have holes or appear scarred. They can also ignite or fail.
1 to 10% of children suffer from Psoriatic arthritis. The affected children usually show signs of illness on the skin or nails first. But these can also be missing. Several joints are usually affected - but not symmetrically. In 2 out of 3 children the disease begins at the knee. Every 3rd to 4th school child also suffers from inflammation of the joints in the sacrum area (sacroiliac joints). But ankle, elbow, wrist or finger joints can also be affected. The affected joint is typically reddened.
Accompanying or independent of the joints, the Tendon attachments ignite. In children, it is usually the heel at the base of the Achilles tendon or the tendon plate on the sole of the foot that is affected. In addition, the tendon attachments on the knee, shoulder blade or iliac crest can become ill.
Finally, a chronic form of the disease can affect young children eyes occur (iridocyclitis). Since there is neither redness nor pain, it will only be recognized during an examination by the ophthalmologist. If pain, redness and photophobia occur, this is the acute form of the disease, which more often affects older children and adolescents and is usually recognized early.
