Psoriasis is NOT contagious , it is a chronic immune-mediated disease that occurs when skin cells grow too quickly.
Faulty signals in the immune system cause new skin cells to form quicker then it suppose to . Due to the occurrence of abnormal
new skin cells formation,the body is unable to shed these excess skin cells, so the cells pile up on the surface of the skin and lesions form.
Psoriatic arthritis is a chronic disease characterized by inflammation of the skin (psoriasis) and joints (arthritis).It is a common skin condition affecting 2.5% of the Caucasian population and 1.3 percent African Americans in the United States .
What are the signs and symptoms?
There are many different types of psoriasis. Each type may be vary in appearance of its form and shape. The common major symptoms of psoriasis include:
Bright red areas of raised patches (plaques) on the skin, often covered with loose, silvery scales. Plaques can occur anywhere,but commonly they occur on the knees, elbows, scalp, hands, feet, or lower back. Tiny areas of bleeding when skin scales are picked or scraped off (Auspitz’s sign). Mild scaling to thick, crusted plaques on the scalp. Itching, especially during sudden flare-ups or when the psoriasis patches are in body folds, such as under the breasts or buttocks.
Nail disorders. Nail disorders are common, especially in severe psoriasis. Nail symptoms include:
Tiny pits in the nails (not found with fungal nail infections).Yellowish discoloration of the toenails and sometimes the fingernails.Separation of the end of the nail from the nail bed.Less often, a buildup of skin debris under the nails.
The lesions vary in appearance with the type of psoriasis. There are five types of psoriasis:
About 80% of people living with psoriasis have plaque psoriasis, also called “psoriasis vulgaris.” Plaque psoriasis causes patches of thick, scaly skin that may be white, silvery, or red. Called plaques (plax), these patches can develop anywhere on the skin.
Psoriasis also can affect the nails. About 50% of people who develop psoriasis see changes in their fingernails and/or toenails.
If the nails begin to pull away from the nail bed or develop pitting, ridges, or a yellowish-orange color, this could be a sign of psoriatic (sore-EE-at-ic) arthritis.
Without treatment, psoriatic arthritis can progress and become debilitating. It is important to see a dermatologist if nail changes begin or joint pain develops.
Early treatment can prevent joint deterioration.
