Disease Of The Skin [HOT]


Skin disease symptoms vary significantly, depending on what condition you have. Skin changes are not always due to skin diseases. For example, you may get a blister from wearing ill-fitting shoes. However, when skin changes show up with no known cause, they may be linked to an underlying condition.

Skin diseases include all conditions that irritate, clog or damage your skin, as well as skin cancer. You may inherit a skin condition or develop a skin disease. Many skin diseases cause itchiness, dry skin or rashes. Often, you can manage these symptoms with medication, proper skin care and lifestyle changes. However, treatment can reduce symptoms and may even keep them at bay for months at a time. Many skin conditions never go away completely. Also, remember to check your skin for any changes, including new or non-healing spots or changes in moles. Most skin cancers can be cured if diagnosed and treated early.


The mission of the National Institute of Arthritis and Musculoskeletal and Skin Diseases is to support research into the causes, treatment, and prevention of arthritis and musculoskeletal and skin diseases; the training of basic and clinical scientists to carry out this research; and the dissemination of information on research progress in these diseases.


Reema Patel is a physician assistant specializing in dermatological skin conditions and aesthetic medicine who has a special interest in treating skin of color. She has previously worked in the emergency room as a physician assistant and for several years in a cosmetic plastic surgery office, gaining experience in aesthetic dermatology.


Many childhood skin problems disappear with age, but children can also inherit permanent skin disorders. In most cases, doctors can treat childhood skin disorders with topical creams, medicated lotions, or condition-specific drugs.


Pregnancy causes significant changes in hormone levels that may lead to skin problems. Preexisting skin problems may change or get worse during pregnancy. Most skin conditions that arise during pregnancy go away after the baby is born. Others require medical attention during pregnancy.


The sun can cause many different skin disorders. Some are common and harmless, while others are rare or life threatening. Knowing if the sun causes or worsens your skin disorder is important for treating it properly.


People with permanent skin conditions often go through periods of severe symptoms. Sometimes people are able to force incurable conditions into remission. However, most skin conditions reappear due to certain triggers, such as stress or illness.


Noninfectious skin disorders, such as acne and atopic dermatitis, are sometimes preventable. Prevention techniques vary depending on the condition. Here are some tips for preventing some noninfectious skin disorders:


According to the American Academy of Dermatology Association, acne is the most common skin condition in the United States. Other common skin disorders include atopic dermatitis, hair loss, and rosacea.


There are several serious skin conditions. In particular, melanoma is a type of skin cancer that can be especially dangerous, as it could spread to other parts of the body if not caught early. Cellulitis and latex allergy can also be very serious if left untreated.


Cutaneous manifestations of thyroid disease are protean in nature and can be divided into specific lesions such as the thyroglossal duct cyst and cutaneous metastases from thyroid malignancy, nonspecific signs secondary to thyroid hormone imbalance, and associated dermatologic and systemic disorders. This review represents a summary and update of thyroid disease and the skin.


Psoriasis is a common, long-term (chronic) disease with no cure. It can be painful, interfere with sleep and make it hard to concentrate. The condition tends to go through cycles, flaring for a few weeks or months, then subsiding for a while. Common triggers in people with a genetic predisposition to psoriasis include infections, cuts or burns, and certain medications.


Ms. Williams: And other issues. Here are six examples: No. 1 is pitting. This could be a sign of psoriasis. Two is clubbing. Clubbing happens when your oxygen is low and could be a sign of lung issues. Three is spooning. It can happen if you have iron-deficient anemia or liver disease. Four is called "a Beau's line." It's a horizontal line that indicates a previous injury or infection. Five is nail separation. This may happen as a result of injury, infection or a medication. And six is yellowing of the nails, which may be the result of chronic bronchitis.


Psoriasis is thought to be an immune system problem that causes skin cells to grow faster than usual. In the most common type of psoriasis, known as plaque psoriasis, this rapid turnover of cells results in dry, scaly patches.


The cause of psoriasis isn't fully understood. It's thought to be an immune system problem where infection-fighting cells attack healthy skin cells by mistake. Researchers believe that both genetics and environmental factors play a role. The condition is not contagious.


In June 2022, WHO published a strategic framework that identifies opportunities to integrate approaches for the control and management of skin NTDs, including common learning platforms, capacity-building for case detection and delivery of treatment. This companion document to the road map emphasizes the three pillars (accelerate programmatic action, intensify cross-cutting approaches, change operating models and culture to facilitate country ownership) to guide implementation of activities.


To facilitate uptake for the control and management of skin NTDs, WHO has developed a manual as well as an interactive mobile phone application (available in both Android and iOS) that not only helps primary health workers to recognize and manage skin NTDs and other common skin conditions, but also provides opportunities for instant exchange of information.


Spending time outside is a great way to be physically active, reduce stress, and get vitamin D.external icon You can work and play outside without raising your skin cancer risk by protecting your skin from the sun.


Most skin cancers are caused by too much exposure to ultraviolet (UV) light. UV rays are an invisible kind of radiation that comes from the sun, tanning beds, and sunlamps. UV rays can damage skin cells.


For the most protection, wear a hat that has a brim all the way around that shades your face, ears, and the back of your neck. A tightly woven fabric, such as canvas, works best to protect your skin from UV rays. Avoid straw hats with holes that let sunlight through. A darker hat may offer more UV protection.


Your skin is your body's largest organ. It has many different functions, including covering and protecting your body. It helps keep germs out. But sometimes the germs can cause a skin infection. This often happens when there is a break, cut, or wound on your skin. It can also happen when your immune system is weakened, because of another disease or a medical treatment.


To diagnose a skin infection, health care providers will do a physical exam and ask about your symptoms. You may have lab tests, such as a skin culture. This is a test to identify what type of infection you have, using a sample from your skin. Your provider may take the sample by swabbing or scraping your skin, or removing a small piece of skin (biopsy). Sometimes providers use other tests, such as blood tests.


The treatment depends on the type of infection and how serious it is. Some infections will go away on their own. When you do need treatment, it may include a cream or lotion to put on the skin. Other possible treatments include medicines and a procedure to drain pus.


The pathogenesis of PG in IBD is proposed to be an abnormal immune response with cross-reacting autoantibodies directed at common antigens in the bowel and skin (Crowson et al., 2003; Feliciani et al., 2009). It is classified as one of the neutrophilic dermatosis. Other factors such as neutrophil dysfunction, abnormal T-cell response, and over-expression of pro-inflammatory cytokines such as IL-8, IL-16, IL-17, and TNF-α have also been proposed as mechanisms in the pathogenesis of PG (Feliciani et al., 2009; Marzano et al., 2010). A case report has implicated the IL-23 and TH17 axis as being responsible for a PG lesion that subsequently resolved with a monoclonal antibody targeted at inhibiting IL-23 expression (Guenova et al., 2011).


The histology of BADAS is characterized by perivascular neutrophilic, mononuclear, and eosinophilic (depending on the stage of the lesions) infiltrate with dermal edema, intraepidermal pustules, minimal alterations of the walls of capillaries and venules without the features of leukocytoclastic vasculitis or fibrinoid necrosis (Georgiou et al., 2006; Nischal and Khopkar, 2007). Similar to PG and SS, BADAS has been classified in the spectrum of aseptic neutrophilic dermatoses with histopathology showing dense neutrophil infiltration and no destruction of vessel walls (Nischal and Khopkar, 2007; Patton et al., 2009). By immunofluorescence staining, the deposition of immunoglobulins and complement has frequently been observed at the dermo-epidermal junction. The pathogenesis of BADAS is hypothesized to be due to immune complex-mediated vessel damage, followed by increased migration and accumulation of neutrophils in the perivascular area (Jorizzo et al., 1984). The circulating immune complexes are believed to form due to an immunological response against antigenic bacterial peptidoglycans in the gut, with subsequent deposition in the skin and joints (Jorizzo et al., 1984; Nischal and Khopkar, 2007; Patton et al., 2009). It is theorized that overgrowth of bacteria, such as seen in active IBD, diverticulitis, appendicitis, blind loop after bypass surgery, or in the inflamed bowel segment after surgery, result in inflammation, and the formation of abnormal immunological responses to bacterial antigens especially peptidoglycans (Georgiou et al., 2006; Patton et al., 2009). Similar pathophysiology is also thought to involve the cutaneous manifestations of EN, PG, and SS (Georgiou et al., 2006; Nischal and Khopkar, 2007). 041b061a72
