Contact Dermatitis

Contact Dermatitis is a medical condition, in which an inflammation is resulted from specific substances; the rashes are confined to a particular region and frequently have clearly Contact Dermatitisrecognized boundaries.

Substance may result in 1 or 2 skin inflammatory mechanisms: allergic contact dermatitis (allergic reaction) or irritant contact dermatitis (irritation). Even too mild specific metals, detergents, and soaps can irritate the person’s skin after frequent contacts. In some cases, repeated exposures (even to water), can dry out and irritate the person’s skin. Strong irritants such as certain organic solvents (for example, polish remover), alkalis (for example, drain cleaners), or acids, can result in skin changes in a several minutes. With the allergic Contact Dermatitis, the 1st exposure to certain substances does not result in reaction, but the next exposure can result in dermatitis and itching within four and twenty four hours.

Individuals can be exposed to substances for years without problems, but then abruptly progress an allergic Contact Dermatitis later on in life. Even lotions, creams, and ointments used to treat dermatitis may result in such a reaction. Appr. 10% of females are allergic to nickel, the most common dermatitis caused from jewelry. Individuals can also progress dermatitis from any material they get in contact with, while working (called occupational dermatitis).

When dermatitis happens after an individual touches specific substances and then exposes the skin to sunlight, the condition is known as Phototoxic Contact Dermatitis. These substances include oils, sunscreen, coal tar, aftershave lotions, antibiotics and specific perfumes. The Contact Dermatitis effects range from mild, short-lived redness to blisters and severe swellings. Frequently, the rash consists of vesicles (tiny itching blisters). At the beginning, such rash is limited only to the contact site, but later, it can spread.

The rash region can be very small (for instance, the earlobes as a result of dermatitis due to earrnings), or it can cover a large body’s region(for instance, if a body lotion results in dermatitis). If the substances resulting in the rash are removed, the redness generally disappears in several days. Blisters can ooze and create crusts, but they soon become dry.

Temporary thickening , residual scaling, and itching of the skin can last for weeks or days. Diagnosis of Contact Dermatitis is not always easy, because of endless possibilities. Also, most individuals are not aware of all substances touching their skin. Frequently, the initial rash location is a major clue. If a dermatologist suggests Contact Dermatitis, but elimination careful process does not indicate the cause, a patch test may be done. For such test, small patches consisting of substances that usually result in dermatitis, are placed on the person’s skin for two days to check if a rash develops beneath 1 of them. Although, this type of testing is fairly complicated.

A dermatologist should determine, when the tests must be performed, how much of each substance to apply, and which substances to test. Also, patch testing results may be difficult to interpret. Tests can be falsely negative or positive. Most individuals may discover their dermatitis source without patch tests by eliminating possible cause. However, patch test may give important clue in defining the cause. Treatment of Contact Dermatitis consists of avoiding or removing whatever results in this condition.

To avoid irritation and prevent infection, an individual must clean the region regularly with soapy water. Blisters must not be cut open. Dry bandages can also prevent infections. Corticosteroid ointment or cream frequently subsides mild Contact Dermatitis symptoms until the individuals have a lot of blistering (as is common in poison ivy). Corticosteroids, such as prednisone in form of tablets are in some cases used for severe Contact Dermatitis cases. Also, antihistamines may be prescribed to relieve itching.
