Psoriasis – eMedTV: Health Information Brought To Life

Psoriasis is a chronic skin disease that causes areas of thickened, swollen, and red skin, often covered with silver scales. In people without psoriasis, skin cells grow deep in the skin and slowly rise to the surface. This process is called cell turnover, and it takes about a month. With psoriasis, it can happen in just a few days because the cells rise too fast and pile up on the surface. This disease affects 2 percent to 2.6 percent of the United States population, or between 5.8 and 7.5 million people. Anyone can get psoriasis, but it occurs more often in adults. Sometimes there is a family history of the disease. Certain genes have been linked to it, and men and women get psoriasis at about the same rate. This condition begins in the immune system, mainly with a type of white blood cell called a T cell. T cells help protect the body against infection and disease. With psoriasis, T cells are put into action by mistake. They become so active that they set off other immune responses. This leads to swelling and fast turnover of skin cells. People with this condition may notice that sometimes the skin gets better and sometimes it gets worse. Things that can cause your symptoms to worsen include: Continue reading

What is Psoriasis? – Medical News Today

knowledge center home eczema / psoriasis all about psoriasis what is psoriasis? Psoriasis is a chronic autoimmune disease that mainly affects the skin. It is non-contagious. A reddish, scaly rash – often referred to as red, scaly patches – is commonly found over the surfaces of the scalp, around or in the ears, the elbows, knees, navel, genitals and buttocks. The scaly patches, also known as psoriatic plaques, are areas of inflammation and excessive skin production. Skin quickly builds up in the affected area, because skin production is faster than the bodys ability to shed it. Areas with psoriatic plaques take on a silvery-white appearance. Unlike eczema, psoriasis is more commonly found on the extensor aspect of a joint. Psoriasis varies in severity – some patients may only have minor localized patches, while others are affected all over the body. Psoriatic nail dystrophy is common among patients with psoriasis – where the fingernails and toenails are affected. Psoriasis may also result in inflammation of the joints, as may be the case with psoriatic arthritis, which affects approximately 10% to 15% of all psoriasis patients. Experts are not sure what causes psoriasis. Most believe there is a genetic component that can be triggered by a prolonged injury to the skin. Excessive alcohol consumption, smoking, mental stress, and withdrawal of systemic corticosteroid medications are said to be factors that may aggravate psoriasis. According to the National Health Service, UK, approximately 2% of the British population is affected by psoriasis. People with psoriasis most commonly develop symptoms between the ages of 11 and 45 years. However, it can start at any age. The human body produces new skin cells at the lowest skin level. Gradually those cells move up through the layers of skin until they reach the outermost level, where they eventually die and flake off. The whole cycle – skin cell production to skin death and flaking off – takes between 21 and 28 days. In patients with psoriasis, the cycle takes only between 2 to 6 days; resulting in a rapid buildup of cells on the skins surface, causing red, flaky, scaly, crusty patches covered with silvery scales, which are then shed. Psoriasis is a chronic condition – it is long lasting. Some people have periods with no symptoms, while others live with signs and symptoms all the time. For some people psoriases can be seriously disabling. Although there is no current cure for psoriasis, there are treatments that can help with the symptoms. According to Medilexicon’s medical dictionary: Psoriasis is A common multifactorial inherited condition characterized by the eruption of circumscribed, discrete and confluent, reddish, silvery-scaled maculopapules; the lesions occur predominantly on the elbows, knees, scalp, and trunk, and microscopically show characteristic parakeratosis and elongation of rete ridges with shortening of epidermal keratinocyte transit time due to decreased cyclic guanosine monophosphate. The word psoriasis comes from the Greek word psoriasis, meaning being itchy.

Psoriasis is a common skin disorder affecting around 2% of people in the UK. Different types of psoriasis cause different symptoms, The most common type, plaque psoriasis, causes thick red plaques covered with silvery scales. Psoriasis image Interactive Medical Media, LLC The most common areas affected are the scalp, elbows, knees, and lower back, although any skin surface may be involved. It can also occur in the nails and body folds. Psoriasis is not contagious and cannot be passed from person to person, but it can occur in members of the same family. Psoriasis usually begins in early adulthood or later in life. In most people, the rash is limited to a few patches of skin; in severe cases, it can cover large areas of the body. The rash can heal and come back again throughout a person’s life. Psoriasis starts as small red bumps, which enlarge and become scaly. The skin appears thick, but bleeds easily if the scales are picked or rubbed off. In addition, the rash may produce: If you have a rash that is not healing, seek medical advice for evaluation of the rash to determine if it is psoriasis. The signs of psoriasis vary depending on the type you have. Some common signs for plaque psoriasis – the most common variety of the condition – include: Psoriasis can also be associated with psoriatic arthritis, which causes pain and swelling in the joints. The Psoriasis Association estimates that between 5% and 7% of people with psoriasis have psoriatic arthritis, but this figure rises to about 40% in people who have severe psoriasis. The exact cause of psoriasis is unknown, but it is believed that a combination of factors contributes to the development of the condition. An abnormality in the immune system causes inflammation in the skin, triggering new skin cells to develop too quickly. Normally, skin cells are replaced every 28 to 30 days. With psoriasis, new cells grow and move to the surface of the skin every three to four days. The build-up of old cells being replaced by new cells creates the silver scales of psoriasis.
