Diseases in News Flashcards
Psoriasis
It is a chronicautoimmune conditionthat causes the rapid buildup of skin cells. This buildup of cells causes scaling on your skin’s surface.
It causes a rash with itchy, scaly patches, most commonly on the knees, elbows, trunk and scalp.
It is a common, long-term (chronic) disease with no cure.
It can be painful, interfere with sleep and make it hard to concentrate.
The condition tends to go through cycles, flaring for a few weeks or months, then subsiding for a while.
It is not contagious.
Causes:
An over-reactiveimmune systemthat creates inflammation in your skin causes psoriasis.
If you have psoriasis, your immune system is supposed to destroy foreign invaders, like bacteria, to keep you healthy and prevent you from getting sick. Instead, your immune system can mistake healthy cells for foreign invaders.
As a result, your immune system creates inflammation or swelling, which you see on the surface of your skin as skin plaques.
Common signs and symptoms of psoriasis include:
raised, inflamed patches of skin that appear red on light skin and brown or purple on dark skin;
whitish-silver scales or plaques on the red patches or grey scales on purple and brown patches;
dry skin that may crack and bleed;
soreness around patches;
itching and burning sensations around patches;
thick, pitted nails;
painful, swollen joints;
Treatment: It has no cure. Treatments aim to
reduce inflammation and scales;
slow the growth of skin cells;
remove plaques;
Common psoriasis treatments include:
Steroid creams.
Moisturizers for dry skin.
Medication to slow skin cell production (anthralin).
Medicated lotions or shampoos.
Vitamin D3 ointment.
Vitamin A or retinoid creams.
