Different Types Of Psoriasis
The most common form of the disease is plaque psoriasis, by far: up to 90% of patients are diagnosed with this type.
But there are other types of psoriasis:
- Pustular psoriasis: patients develop pustules , filled with non-infectious liquid
- Inverse psoriasis: typically affects skin folds like around the genitals, the armpits or under the breasts
- Napkin psoriasis: common in infants, it causes scaling in the diaper area
- Guttate psoriasis: small droplet-like spots appear on the body
- Erythrodermic psoriasis: widespread inflammation and scaling this form of the disease often affects over 90% of the body
- Mouth psoriasis: although very rare, psoriasis can affect the mouth, appearing as grey or yellowish plaques
- Nail psoriasis: rarely found separately, this form of the disease specifically targets nails, which become harder than usual and can therefore crack, break or even separate from the nail bed

is one form of that affects plastics exposed to . The problem appears as discoloration or fading, cracking, loss of strength or disintegration. The effects of attack increase with exposure time and sunlight intensity. The addition of UV absorbers inhibits the effect.
Sensitive polymers include and speciality fibers like . UV absorption leads to chain degradation and loss of strength at sensitive points in the chain structure. Aramid rope must be shielded with a sheath of thermoplastic if it is to retain its strength.
Many and absorb UV and change colour, so and textiles may need extra protection both from sunlight and fluorescent bulbs, two common sources of UV radiation. Window glass absorbs some harmful UV, but valuable artifacts need extra shielding. Many museums place black curtains over and ancient textiles, for example. Since watercolours can have very low pigment levels, they need extra protection from UV. Various forms of , including acrylics , laminates, and coatings, offer different degrees of UV protection.
What Is Cdc Doing About Psoriasis
In 2010, CDC worked with experts in psoriasis, psoriatic arthritis, and public health to develop a public health perspective that considers how these conditions affect the entire population. The resulting report is Developing and Addressing the Public Health Agenda for Psoriasis and Psoriatic Arthritis pdf icon. You can read a short article about the agendaexternal icon in The American Journal of Preventive Medicine.
CDCs National Health and Nutrition Examination Survey , an intermittent source of national psoriasis data, has included questions about psoriasis as late as the 2013-2014 cycle. A recent analysis of NHANES data estimates that 7.4 million adults had psoriasis in 2013external icon.
- Psoriasis causes patches of thick red skin and silvery scales. Patches are typically found on the elbows, knees, scalp, lower back, face, palms, and soles of feet, but can affect other places . The most common type of psoriasis is called plaque psoriasis.
- Psoriatic arthritis is an inflammatory type of arthritis that eventually occurs in 10% to 20% of people with psoriasis. It is different from more common types of arthritis and is thought to be related to the underlying problem of psoriasis.
- Psoriasis and psoriatic arthritis are sometimes considered together as psoriatic disease.

Psoriasis Causes Symptoms Treatment
Psoriasis is a common inflammatory disease of the skin which affects 2-3% of New Zealanders.
Characteristic symptoms are thick, red skin, with flaky, silver-white patches. These patches can be small and may or may not be itchy and sore. More severe cases can cover large areas of the body and have a major impact on quality of life. The aim of treatment is to minimise symptoms and prevent infection of the skin.
Psoriasis is often a life-long condition. Anyone can get psoriasis, but it is more likely to occur in people aged between 15 and 35 years and those aged between 50 and 60 years. It is not contagious, i.e. it cannot be caught from or spread to another person.
There are several different types of psoriasis, each with its own distinctive appearance. Some people will develop stiff swollen joints in combination with their psoriasis a condition known as psoriatic arthritis. The persistent visual, and sometimes disabling, nature of psoriasis can result in social, psychological, and economic consequences for people with the condition. Hence, it is important to seek effective treatment and support.
What Are The Symptoms Of Psoriasis
Psoriasis happens to anyone despite race, gender, age, and skin colour. Although psoriasis commonly carry the same attributes, symptoms may vary from one another. Some people may develop all the symptoms, and some may only have half of it.
The most common symptoms of psoriasis include:
- Red, raised, thick and inflamed patches of skin
- Itchy, dry skin that may crack and bleed
- Whitish-silver scales or plaques on the patches
- Thick, pitted fingernails and toenails.
- Scaly plaques on the scalp
- Soreness around patches
There are several types of psoriasis including:
Plaque psoriasis/ psoriasis vulgaris
Also known as psoriasis vulgaris. It is the most common type of psoriasis. It appears in a form of whitish-silver scales or plaques that covers the patches and cause redness and inflamed on the skin. This skin condition is commonly found on the elbows, knees, and scalp.
Guttate psoriasis
Commonly appear as small, pink and teardrop-shaped spots at the torso, arms and legs. It usually happens during childhood or young adult and not as common as plaque psoriasis.
Inverse psoriasis
Inverse psoriasis is a skin condition that develops in the folds of the skin where it sweats more and sensitive compared to the other parts. It can be seen at the armpits, under the breasts, groin, skin around genitals and between the buttocks. Lesions may cause itching, pain and bleeding to the affected area.

Psoralen Plus Ultraviolet A
For this treatment, you’ll first be given a tablet containing compounds called psoralens, or psoralen may be applied directly to the skin. This makes your skin more sensitive to light. Your skin is then exposed to a wavelength of light called ultraviolet A . This light penetrates your skin more deeply than ultraviolet B light.
This treatment may be used if you have severe psoriasis that hasn’t responded to other treatment. Side effects of the treatment include nausea, headaches, burning and itchiness. You may need to wear special glasses for 24 hours after taking the tablet to prevent the development of cataracts. Long-term use of this treatment isn’t encouraged, as it can increase your risk of developing skin cancer.
What Are Other Types Of Psoriasis
Plaque psoriasis is the most common type. About 80% to 90% of people with psoriasis have plaque psoriasis.
Other, less common types of psoriasis include:
- Inverse psoriasis appears in skin folds. It may look like thin pink plaques without scale.
- Guttate psoriasis may appear after a sore throat caused by a streptococcal infection. It looks like small, red, drop-shaped scaly spots in children and young adults.
- Pustular psoriasis has small, pus-filled bumps on top of the red patches or plaques.
- Sebopsoriasis typically appears on the face and scalp as red bumps and plaques with greasy yellow scale. This type is a cross between psoriasis and seborrheic dermatitis.

Problems With The Immune System
Your immune system is your body’s defence against disease and it helps fight infection. One of the main types of cell used by the immune system is called a T-cell.
T-cells normally travel through the body to detect and fight invading germs, such as bacteria. But in people with psoriasis, they start to attack healthy skin cells by mistake.
This causes the deepest layer of skin to produce new skin cells more quickly than usual, triggering the immune system to produce more T-cells.
It’s not known what exactly causes this problem with the immune system, although certain genes and environmental triggers may play a role.
Psoriasis: More Than Skin Deep
The first accurate medical discussion of psoriasis dates back to 1801, but the disease itself is much older. In fact, its very name is borrowed from an ancient Greek word meaning an itchy or scaly condition. About 7 million Americans are plagued by this itching and scaling, and many of them have serious complications involving other organs. Although psoriasis is classified as a dermatologic disease, it doesn’t start in the skin, and its damage may be more than skin deep.

Ultraviolet absorbers are molecules used in organic materials to absorb UV radiation to reduce the of a material. The absorbers can themselves degrade over time, so monitoring of absorber levels in weathered materials is necessary.
In , ingredients that absorb UVA/UVB rays, such as , and , are or “blockers”. They are contrasted with inorganic absorbers/”blockers” of UV radiation such as , , and .
For clothing, the represents the ratio of -causing UV without and with the protection of the fabric, similar to ratings for . Standard summer fabrics have UPFs around 6, which means that about 20% of UV will pass through.
Suspended nanoparticles in stained-glass prevent UV rays from causing chemical reactions that change image colors. A set of stained-glass color-reference chips is planned to be used to calibrate the color cameras for the 2019 Mars rover mission, since they will remain unfaded by the high level of UV present at the surface of Mars.

Is It Scalp Psoriasis Or Dandruff
More than half of all psoriasis patients have scalp psoriasis, according to the NPF. Itchy plaques can extend beyond the hairline onto the forehead, neck, and around the ears.
“Most people with scalp psoriasis have it on other parts of their body as well,” says Dina D. Strachan, MD, a dermatologist and assistant clinical professor of dermatology at NYU Langone Medical Center in New York City.
Scalp psoriasis is sometimes confused with seborrheic dermatitis, or dandruff. According to Dr. Strachan, dandruff which causes a flaky, itchy scalp without signs of inflammation tends to itch more than scalp psoriasis. It has a greasy-appearing yellow scale, Strachan says. In contrast, psoriasis whether it’s on your scalp or any other body part tends to have a thick, silvery scale.”
Uncommon Types Of Psoriasis
Some uncommon types of psoriasis can have more serious effects.
Erythrodermic psoriasis causes all of the skin on the body to become red and scaly. This form of psoriasis is serious because, like a burn, it keeps the skin from serving as a protective barrier against injury and infection.
Pustular psoriasis is another uncommon form of psoriasis. In this form, large and small pus-filled blisters are scattered widely on the body.
Palmoplantar psoriasis is a form of pustular psoriasis in which pustules occur primarily on the hands and feet. It is sometimes called palmoplantar psoriasis of the palms and soles.

What Is Fatty Liver Disease
NAFLD is caused by the accumulation of fat in the liver. The liver is essential because it processes nutrients and regulates the immune system, digestion, hormones, cholesterol, blood sugar, and blood clotting. When lipids build up, it can impair normal liver function and lead to NAFLD.
Nonalcoholic fatty liver disease is often mild and may only be detectable in lab tests. However, NAFLD can progress to nonalcoholic steatohepatitis . With NASH, cells in the liver are damaged. NASH can further progress to liver fibrosis and cirrhosis as well as liver failure or cancer.
Inflammation And Psoriasis: Making The Connection
The immune system and inflammation play a role in psoriasis. Heres how theyre believed to be connected.
Think of the immune system as your bodys alarm system. When you get a cold, infection, or scrape on your knee, your immune system sends out signals that trigger inflammation in an effort to defend itself.
When you have psoriasis, your immune system is out of balance. In fact, its in overdrive. An overactive immune system can send faulty signals and mistake healthy cells for harmful ones. This results in too much inflammation. For psoriasis patients, this means the body rapidly produces more skin cells than necessary.
Luckily, some treatment options can reduce inflammation, which may help the immune system and help to slow the rapid production of skin cells.

Taking Care Of Your Skin
Injuries to the skin, such as sunburns and scrapes, can trigger psoriasis in some people. These types of injuries can usually be prevented by practicing good skin care.
When doing activities that may cause skin injury, you should always take extra precautions. Use sunscreen and wear a hat when spending time outside. You should also use caution when engaging in outdoor activities and contact sports, such as basketball or football.
How Do Psoriasis Treatments Affect The Liver
Systemic therapy may be used for moderate to severe psoriasis to manage symptoms. However, systemic treatments can have varying effects on the liver.
Methotrexate is a psoriasis treatment that can cause NAFLD. People with metabolic syndrome may have a higher risk of NAFLD on methotrexate treatment. People taking methotrexate should monitor their liver function carefully. Talk to your doctor about the benefits and risks of methotrexate regarding your psoriasis and your liver.
Biologic treatments for psoriasis have a varied effect on liver disease as well. To detect these issues, the use of these medications requires regular blood testing and monitoring by your physician.

How Does Psoriasis Develop
Patients afflicted with psoriasis have abnormal skin: the upper layer of the skin overdevelops and skin cells that normally reproduce in a months time are replaced within a week.
This overabundance of skin cells is responsible for all symptoms and is the consequence of the autoimmune reaction: white blood cells move from the dermis to the epidermis and start producing proteins which stimulate skin production.
Also, dying cells produce the same proteins, aggravating the process and causing the already abnormal skin production to increase even further.
What Kind Of Disease Is Psoriasis: How Does It Manifest
With this disease, pimples and patches appear on the skin. Plaques are pink or red tones on the skin, clearly limited, compacted spots with small light scales. Plaques come in different shapes, but more commonly they are round or oval. They can be located on any part of the body, but are more common in the large joints, sacrum and lower back, and under the hair on the head.
Psoriasis papules are characterized by rapid growth, forming plaques of a few centimeters, which then merge into large skin lesions.

What Can I Do To Reduce My Risk Of Fatty Liver Disease
Reducing risk factors for metabolic disease and liver disease is likely the best approach to minimize the risk of NAFLD. For individuals who are overweight, weight loss is an important step for preventing and treating NAFLD. Clinical research studies have shown that even a 5 percent weight loss can improve NAFLD. Your doctor or a nutritionist can help you get started on a diet and exercise plan that works for you.
Controlling alcohol intake is another approach to reduce the risk of liver disease. The liver removes molecules that can harm the body, including alcohol. Limiting or avoiding alcohol consumption can help reduce stress on the liver.
Consuming coffee and caffeine may also help protect your liver, research suggests. A review of studies showed that people diagnosed with NAFLD or NASH who drank caffeinated coffee regularly had lower levels of liver fibrosis.
People with NAFLD who have low levels of vitamin D may benefit from vitamin D supplements.
What Causes Psoriasis Outbreaks
Psoriasis outbreaks differ from person to person. No one knows exactly what causes flare-ups. Common psoriasis triggers may include:
- Skin injury .
- Streptococcal or other infection that affects the immune system.
- Certain prescription medications .
- Cold weather, when people have less exposure to sunlight and humidity and more to hot, dry indoor air.
