Seborrheic Dermatitis The word "eczema" has come to mean a great variety of inflammatory, scaly, itchy skin conditions. One person may have atopic dermatitis and another seborrheic dermatitis, but they both describe their conditions as "eczema". Seborrheic Dermatitis Seborrheic dermatitis is a relatively common skin condition that usually is easily recognized and differentiated from other eczematous conditions. Its characteristics are: • Reddened, somewhat swollen patches of skin; and, • Yellowish-brown scales and crusts on affected areas of the skin, frequently on the scalp (a common cause of dandruff), and around the nose and mouth. • Seborrheic dermatitis is common in infancy and can occur again after puberty and in adulthood. Its cause is unknown. Unlike acne, which also has increased sebum production, seborrheic dermatitis is not a disease of the hair follicles and attendant sebaceous glands. The following photos are characteristic examples of seborrheic dermatitis: In adults, seborrheic dermatitis can resemble psoriasis, especially on the scalp. In some patients with a genetic predisposition for psoriasis, seborrheic dermatitis may be a forerunner or trigger for psoriasis Seborrheic Dermatitis in Infants The typical form of seborrheic dermatitis in infancy is "cradle cap"—oily scales and crusts on hairy portions of the scalp that may extend to the face and neck. The groin and armpits may also be affected, resembling "diaper rash." The infant form of seborrheic dermatitis is usually self-limiting and disappears after a period of weeks to months. A dermatologist to relieve symptoms and to be sure that the condition is not atopic dermatitis—a condition requiring different management, should treat seborrheic dermatitis. Seborrheic Dermatitis in Adults The manifestations of the mildest form of seborrheic dermatitis in adults are oily- appearing skin, scaling skin, mild skin redness, and itching of eyelids, scalp, face and body. Scaling skin on the scalp often presents as dandruff. In young women, especially, seborrheic dermatitis often occurs in the facial areas around the mouth and nose. In its more severe form of patchy seborrheic dermatitis, more areas of the body are covered and lesions are more severe. Adult seborrheic dermatitis often persists for years to decades and may be associated with Parkinson’s disease and other neurological disorders. The disease may worsen in cold weather and improve in warm weather. A dermatologist’s examination must differentiate seborrheic dermatitis from other skin conditions such as atopic dermatitis, contact dermatitis, rosacea, and psoriasis. Treatment of seborrheic dermatitis is directed toward loosening and removing scales and crusts, preventing skin infections, and reducing inflammation and itching. Standbys of treatment include daily shampoos with a product recommended by a dermatologist, topical steroids, anti-bacterial and anti-fungal agents, and anti-itch medications. Infant and adult forms of seborrheic dermatitis may require different formulations and applications of standard treatment. .

Genital Lichen Simplex Chronicus (Eczema, Neurodermatitis, Dermatitis) !
Libby Edwards, MD Genital Lichen Simplex Chronicus (eczema, neurodermatitis, dermatitis) ! Lichen simplex chronicus (LSC), or eczema, is a common skin condition that is very itchy. Although not dangerous in any way, both the itching, and the pain from rubbing and scratching, can be miserable. Eczema/LSC of the genital area most often affects the scrotum of men, the vulva of women, or the rectal skin of both. Many people with eczema/LSC have had sensitive skin or eczema/LSC on other areas of the skin at some point, and many have a tendency towards allergies, especially hay fever or asthma. ! The skin usually appears red or dark, and thick from rubbing and scratching, sometimes with sores from scratching. ! The cause of eczema/LSC is not entirely clear. However, eczema/LSC starts with irritation that triggers itching. Often, at the office visit with the health care provider, the original infection or other initial cause of irritation is no longer present. Common triggers include a yeast or fungus infection, an irritating medication, moisturizer or lubricant, a wet bathing suit, anxiety or depression, over-washing, panty liners, sweat, heat, urine, a contraceptive jelly, an irritating condom, or any other activity or substance that can irritate the skin and start the itching. ! Although rubbing and scratching often feel good at first, rubbing irritates the skin and ultimately makes itching even worse, so that there is more scratching, then more itching, then more scratching. This is called the “itch-scratch cycle.” Treatment is very effective and requires clearing any infection and avoiding irritants as well as using a strong cortisone.

Lichen Simplex Chronicus
LICHEN SIMPLEX CHRONICUS http://www.aocd.org Lichen simplex chronicus is a localized form of lichenified (thickened, inflamed) atopic dermatitis or eczema that occurs in well defined plaques. It is the result of ongoing, chronic rubbing and scratching of the skin in localized areas. It is generally seen in patients greater than 20 years of age and is more frequent in women. Emotional stress can play a part in the course of this skin disease. There is mainly one symptom: itching. The rubbing and scratching that occurs in response to the itch can become automatic and even unconscious making it very difficult to treat. It can be magnified by seeming innocuous stimuli such as putting on clothes, or clothes rubbing the skin which makes the skin warmer resulting in increased itch sensation. The lesions themselves are generally very well defined areas of thickened, erythematous, raised area of skin. Frequently they are linear, oval or round in shape. Sites of predilection include the back of the neck, ankles, lower legs, upper thighs, forearms and the genital areas. They can be single lesions or multiple. This can be a very difficult condition to treat much less resolve. It is of utmost importance that the scratching and rubbing of the skin must stop. Treatment is usually initiated with topical corticosteroids for larger areas and intralesional steroids might also be considered for small lesion(s). If the patient simply cannot keep from rubbing the area an occlusive dressing might be considered to keep the skin protected from probing fingers. Since this is not a histamine driven itch phenomena oral antihistamines are generally of little use in these cases.

Swimmer's Itch Fact Sheet
Fact Sheet for the general public Swimmer’s Itch (Cercarial Dermatitis) What is swimmer's itch? Swimmer's itch, also called cercarial dermatitis (sir-CARE-ee-uhl der-muh-TIGHT-iss), appears as a skin rash caused by an allergic reaction to certain parasites that infect some birds and mammals. These microscopic parasites are released from infected snails into fresh and salt water (such as lakes, ponds, and oceans). While the parasite’s preferred host is the specific bird or mammal, if the parasite comes into contact with a swimmer, it burrows into the skin causing an allergic reaction and rash. Swimmer’s itch is found throughout the world and is more frequent during summer months. How does water become infested with the parasite? The adult parasite lives in the blood of infected animals such as ducks, geese, gulls, swans, and certain aquatic mammals such as muskrats and beavers. The parasites produce eggs that are passed in the feces of infected birds or mammals. If the eggs land in or are washed into water, the eggs hatch, releasing small, free-swimming larvae. These larvae swim in the water in search of a certain species of aquatic snail. If the larvae find one of these snails, they infect the snail, multiply and undergo further development. Infected snails release a different type of larvae (or cercariae, hence the name cercarial dermatitis) into the water. This larval form then swims about searching for a suitable host (bird, muskrat) to continue the life cycle. Although humans are not suitable hosts, the larvae burrow into the swimmer’s skin, and may cause an allergic reaction and rash.

How to Treat Dandruff
HOW TO TREAT DANDRUFF Dandruff is a common scalp condition in which small pieces of dry skin flake off of the scalp. The most effective way to treat and control dandruff is to use dandruff shampoo and scalp treatments. Follow these tips from dermatologists to get the best results. Dandruff is a common scalp condition in which small pieces of dry skin flake off of the scalp. If you have dark hair or you’re wearing dark colors, you may notice the flakes in your hair or on your shoulders. Dandruff may also make your scalp itch. Many people believe that dandruff is caused by poor hygiene, but this is not true. Although infrequent shampooing can make dandruff more obvious, researchers are still studying the causes, which appear to be complex. The most effective way to treat and control dandruff is to use dandruff shampoo and scalp treatments. Follow these tips from dermatologists to get the best results: 1. Follow the instructions on the dandruff shampoo bottle. There are many different dandruff shampoos, and each contains different active ingredients for controlling symptoms. To get the best results, always follow the instructions on the bottle. For example, some dandruff shampoos require that you lather the shampoo into the hair and scalp and leave the shampoo in for about five minutes before rinsing. Others should not be left on the scalp. 2. If you are Caucasian or Asian, shampoo daily and use dandruff shampoo twice a week. If using one dandruff shampoo does not bring relief, try alternating between dandruff shampoos with different active ingredients.

Lichen Simplex Chronicus (Lsc)
Buffalo Medical Group, P.C. Robert E. Kalb, M.D. Phone: (716) 630-1102 Fax: (716) 633-6507 Department of Dermatology 325 Essjay Road Williamsville, New York 14221 LICHEN SIMPLEX CHRONICUS (LSC) Lichen simplex chronicus is a form of eczema in the skin. It produces red inflamed scaling and itching areas. The first part of the word lichen refers to the fact that the area is slightly raised. The second part of the word simplex means it is the simple form of the condition. The third word chronicus refers to the fact that the problem tends to be present for many months or in some cases years. The exact cause of lichen simplex is unknown. In many cases the problem, which caused the original skin condition, has long since gone away. The original condition, however, set up a pattern where the skin was itched and scratched. This caused more itching and more scratching. Eventually this creates an itch/scratch cycle, which allows the condition to persist. This is despite the fact that the original problem is gone. In many cases, nerves and stress contribute to this itch/scratch cycle. Patches of lichen simplex can be seen in any area of the body. Some of the more common areas are the neck, private area, and around the ankles. Some patients have only one spot on the skin. Some patients have a large number of areas. Lichen simplex is not a sign of an internal problem. It is not a sign of cancer or any contagious skin problem. Fortunately, lichen simplex can be controlled in most cases.

Interdry for Intertrigo
pat hways InterDry for intertrigo Medtech innovation briefing Published: 10 September 2019 www.nice.org.uk/guidance/mib192 Summary • The technology described in this briefing is InterDry. It is used for treating intertrigo, a common inflammatory skin ashr that usually develops in skin folds, such as in the groin, under the breast or in the armpits. • The innovative aspects are that the technology is designed to target all 3 factors associated with intertrigo: moisture, bacteria or fungi and friction from skin-to-skin contact. • The intended place in therapy would be as an alternative to other treatment options used in managing intertrigo. This may include topical or systemic antimicrobial agents and corticosteroids, and absorptive materials such as gauze. • The main points from the evidence summarised in this briefing are from 1 prospective single- arm observational study, 2 case series and 2 case reports including a total of 28 adults with intertrigo or complications associated with skin folds. Evidence suggests that InterDry may help to reduce the symptoms of intertrigo, including itching or burning, loss of skin layers, secondary lesions, redness and odour. • Key uncertainties around the technology are that the available evidence is very limited in quantity and quality. Well-designed comparative studies would be helpful to determine the benefits vo er current management options. The care pathway for intertrigo in the UK is not well defined and standard care may vary. © NICE 2020. All rights reserved. Subject to Notice of rights (https://www.nice.org.uk/terms-and- Page 1 of conditions#notice-of-rights). 12 InterDry for intertrigo (MIB192) • The cost of InterDry is £43.07 for the 25 cm × 91 cm pouch and £105.95 for the 25 cm × 366 cm roll (exclusive of VAT).
