Contact Dermatitis Knowledge Study – Symptoms, Causes, Diagnosis & Treatment

Contact dermatitis is a red, itchy rash that originated from direct contact with a substance or an allergic reaction to it. The rash isn’t contagious or life-threatening, but it can be very problematic and irritating.
Many substances can create such reactions, including soaps, cosmetics, fragrances, jewelry, and plants.
To treat contact dermatitis successfully, you have to identify and neglect the production of your reaction. If you can ignore the offending substance, the rash clears typically up in two to four weeks. You can try to soothe your skin with cold, wet compresses, anti-itch creams, and other self-care steps. This is another severe dermatitis after Atopic dermatitis.

Causes of Contact Dermatitis

Contact dermatitis is caused by a substance you’re exposed to that irritates your skin or hits an allergic reaction. The content could be one of the thousands of known allergens and irritants. Some of these substances may occur both irritant contact dermatitis and allergic contact dermatitis. Irritant contact dermatitis is the most common type of contact dermatitis. This nonallergic skin reaction arises when a substance injures your skin’s outer protective layer. Some people react to strong irritants after a single exposure. Others may promote signs and symptoms after repeated exposure to even little irritants. And some people promote tolerance to the substance over time.
Common Causes of Contact Dermatitis include:

1) Solvents
2) Rubbing alcohol
3) Bleach and detergents
4) Shampoos, permanent wave solutions
5) Airborne substances, such as sawdust or wool dust Plants
6) Fertilizers and pesticides
Allergic contact dermatitis arises when a material to which you’re sensitive (allergen) hits an immune reaction in your skin. It generally damages only the area that came into contact with the allergen. But it may be hit by something that enters your body through foods, flavorings, medicine, or medical or dental procedures (systemic contact dermatitis).
You may become sensitized to a potent allergen like poison ivy after a single exposure. Weaker allergens may need multiple exposures over many years to hit an allergy. Once you promote an allergy to a substance, even a small amount of it can cause a reaction.

Risk factors of Contact Dermatitis

Some jobs and hobbies place you at a higher risk of contact dermatitis. Examples consist:

1) Health care and dental employees
2) Metalworkers
3) Construction workers
4) Hairdressers and cosmetologists

8) Gardeners and agricultural workers
9) Cooks and others who work with food

Complications of Contact Dermatitis

Contact dermatitis complications can lead to an infection if you repeatedly scratch the injured area, making it wet and oozing. This creates the right place for bacteria or fungi to grow and may occur an infection.

Diagnosis procedure of Contact Dermatitis

The doctor may be able to diagnose contact dermatitis and identify its cause by consulting to you about your signs and symptoms, asking you to disclose clues about the target substance, and testing your skin to note the pattern and intensity of your rash. The doctor may suggest a patch test to identify if you’re allergic to something. This test can be beneficial if the cause of your outbreak isn’t apparent or if your rash recurs sometimes.
During a patch test, small amounts of potential allergens are used to adhesive patches, which are then put on your skin. The pieces remain on your skin for two to three days, during which time you’ll require to keep your back dry. The doctor then monitors for skin reactions under the patches and determines whether further testing is needed. These are the diagnosis procedure of Contact Dermatitis.

Treatments of Contact Dermatitis

If home care steps don’t ease your signs and symptoms, the doctor may prescribe medications. Examples consist:

1) Steroid creams or ointments: These topically used creams or lotions help to soothe the rash of contact dermatitis. A topical steroid may be used one or two times a day for two to four weeks.
2) Oral medications: In chronic cases, your doctor may suggest oral corticosteroids to decrease inflammation, antihistamines to relieve itching or antibiotics to fight a bacterial infection.
