The symptoms may vary from small scaling spot (which is seen in children), dry, cracked skin which results in bleeding, itching, burning or soreness, thickening and ridging of nails or swollen and stiff joints. Most types of Psoriasis go through cycle of flaring for a few weeks or months to subsiding for a time or going into remission. However in most cases it returns. They generally occur in elbow, knee, scalp, trunk and nails. The different type of psoriasis includes plague psoriasis, nail psoriasis, scalp psoriasis, guttate psoriasis, inverse psoriasis, erythrodermic psoriasis, and psoriatic arthritis.

What causes Psoriasis?

Research says that disorder in the immune system causes psoriasis. Scientist thinks that an abnormal immune system which produces too many of the white blood cell in the skin leads to psoriasis. These trigger inflammation and flaking of skin. In some cases psoriasis is inherited. People affected by psoriasis may see that their skin worsens, and then improves. Psoriasis aggravates due to changes in climate, infections, stress and dry skin. Medicines like nonsteroidal anti-inflammatory drug indomethacin which treats high blood pressure or depression might worsen the disease. Stress, alcohol, smoking should be avoided to prevent psoriasis.

What’s the treatment for Psoriasis?

Moderate sun exposure improves psoriasis but if you are out for a long period a sunscreen is must. Topical lotion, creams, gels, shampoos can help in moderate cases. Coal tar has been used since the beginning of the century to treat Psoriasis. But where the ointments won’t penetrate, corticosteroids, ultraviolet light and cortisone injected into scalp, elbows, toes, and legs can help. Oral treatment, immunobiologics, light therapy, and combination of phototherapy and drugs are used in other serious cases. But research is continuing to find out reasons for the cause of
Psoriasis, what genes are responsible for the disease and find out an eventual cure to this problem.
