A few days back came the horrendous news of Kim Kardashian. Kim was diagnosed suffering from Psoriasis. When Kim Kardashian stepped out on July 19 with red marks on her calves, bloggers ended up swift to point out the odd spots – which appeared like bug bites – covering the truth star’s legs (watch photo). Read far more detail (with bigger photo at ICYDK.Com. What is Psoriasis ? According to MayoClinic, Psoriasis is a common skin disease that affects the life cycle of skin cells. Psoriasis causes cells to build up rapidly on the surface of the skin, forming thick silvery scales and itchy, dry, red patches that are sometimes painful. Psoriasis Symptoms Psoriasis signs and symptoms can vary from person to person but may include one or more of the following: Red patches of skin covered with silvery scales Small scaling spots (commonly seen in children) Dry, cracked skin that may bleed Itching, burning or soreness Thickened, pitted or ridged nails Swollen and stiff joints
Psoriasis ( /səˈraɪ.əsɨs/) is a chronic immune-mediated disease that appears on the skin. It occurs when the immune system sends out faulty signals that speed up the growth cycle of skin cells. Psoriasis is not contagious.[1] There are five types of psoriasis: plaque, guttate, inverse, pustular and erythrodermic. The most common form, plaque psoriasis, is commonly seen as red and white hues of scaly patches appearing on the top first layer of the epidermis (skin). Some patients, though, have no dermatological symptoms. In plaque psoriasis, skin rapidly accumulates at these sites, which gives it a silvery-white appearance. Plaques frequently occur on the skin of the elbows and knees, but can affect any area, including the scalp, palms of hands and soles of feet, and genitals. In contrast to eczema, psoriasis is more likely to be found on the outer side of the joint. The disorder is a chronic recurring condition that varies in severity from minor localized patches to complete body coverage. Fingernails and toenails are frequently affected (psoriatic nail dystrophy) and can be seen as an isolated symptom. Psoriasis can also cause inflammation of the joints, which is known as psoriatic arthritis. Between 10% and 40% of all people with psoriasis have psoriatic arthritis.[2][citation needed] The cause of psoriasis is not fully understood, but it is believed to have a genetic component and local psoriatic changes can be triggered by an injury to the skin known as the Koebner phenomenon,[3] see Koebnerisin. Various environmental factors have been suggested as aggravating to psoriasis, including stress, withdrawal of systemic corticosteroid, as well as other environmental factors, but few have shown statistical significance.[4] There are many treatments available, but because of its chronic recurrent nature, psoriasis is a challenge to treat.
Classification The symptoms of psoriasis can manifest in a variety of forms. Variants include plaque, pustular, guttate and flexural psoriasis. This section describes each type (with ICD-10 code [5]).[6] Psoriasis is a chronic relapsing disease of the skin that may be classified into nonpustular and pustular types as follows[7]: [edit] Nonpustular Psoriasis vulgaris (chronic stationary psoriasis, plaque-like psoriasis)(L40.0) is the most common form of psoriasis. It affects 80 to 90% of people with psoriasis. Plaque psoriasis typically appears as raised areas of inflamed skin covered with silvery white scaly skin. These areas are called plaques. Psoriatic erythroderma (erythrodermic psoriasis)(L40.85)involves the widespread inflammation and exfoliation of the skin over most of the body surface. It may be accompanied by severe itching, swelling and pain. It is often the result of an exacerbation of unstable plaque psoriasis, particularly following the abrupt withdrawal of systemic treatment. This form of psoriasis can be fatal, as the extreme inflammation and exfoliation disrupt the body's ability to regulate temperature and for the skin to perform barrier functions.[8] [edit] Pustular Pustular psoriasis (L40.1-3, L40.82) appears as raised bumps that are filled with noninfectious pus (pustules). The skin under and surrounding the pustules is red and tender. Pustular psoriasis can be localised, commonly to the hands and feet (palmoplantar pustulosis), or generalised with widespread patches occurring randomly on any part of the body. Types include: Generalized pustular psoriasis (pustular psoriasis of von Zumbusch) Pustulosis palmaris et plantaris (persistent palmoplantar pustulosis, pustular psoriasis of the Barber type, pustular psoriasis of the extremities) Annular pustular psoriasis Acrodermatitis continua Impetigo herpetiformis [edit] Other Additional types of psoriasis include[9]: Drug-induced psoriasis Inverse psoriasis (flexural psoriasis, inverse psoriasis)(L40.83-4) appears as smooth inflamed patches of skin. It occurs in skin folds, particularly around the genitals (between the thigh and groin), the armpits, under an overweight abdomen (panniculus), and under the breasts (inframammary fold). It is aggravated by friction and sweat, and is vulnerable to fungal infections. Napkin psoriasis Seborrheic-like psoriasis Guttate psoriasis (L40.4) is characterized by numerous small, scaly, red or pink, teardrop-shaped lesions. These numerous spots of psoriasis appear over large areas of the body, primarily the trunk, but also the limbs and scalp. Guttate psoriasis is often preceded by a streptococcal infection, typically streptococcal pharyngitis. The reverse is not true. Nail psoriasis (L40.86) produces a variety of changes in the appearance of finger and toe nails. These changes include discolouring under the nail plate, pitting of the nails, lines going across the nails, thickening of the skin under the nail, and the loosening (onycholysis) and crumbling of the nail. Psoriatic arthritis (L40.5) involves joint and connective tissue inflammation. Psoriatic arthritis can affect any joint, but is most common in the joints of the fingers and toes. This can result in a sausage-shaped swelling of the fingers and toes known as dactylitis. Psoriatic arthritis can also affect the hips, knees and spine (spondylitis). About 10–15% of people who have psoriasis also have psoriatic arthritis. The migratory stomatitis in the oral cavity mucosa and the geographic tongue that confined to the dorsal and lateral aspects of the tongue mucosa, are believed to be oral manifestations of psoriasis, as being histologically identical to cutaneous psoriasis lesions and more prevalent among psoriasis patients[10], although these conditions are quite common in the non-psoriatic population, affecting 1% to 2.5% of the general population.[10]
