Contact Dermatitis is widely confused with Atopic eczema as they create almost similar rashes and lesions on the body surface. However, once they are confirmed through Biopsy, it can be found with a retrograde line of thinking that they have their own attributes and specific symptoms too. While Atopic eczema is hereditary, Contact Dermatitis is caused by allergens scouring over the skin surface. It’s a localized rash that requires some foreign object to interfere with the skin. The skin tissues are only affected at the topmost layer and there is no sign of damage beneath the exoderm or the outer integument.
It is not chronic in nature (again quite a departure from eczema and its various forms) and the rashes and lesions disappear within a few days. However, this can happen with a steady line of treatment and again, there should not be any contact with the specific allergens during the period of convalescence. There would be times when you clearly mark out that the elimination of allergens does not provide you relief as expected; this is a sure case of having developed the syndrome.
Contact Dermatitis ramifies into three branches. These are the Irritant Contact Dermatitis, Allergic Contact Dermatitis and Photocontact Contact Dermatitis. Phototoxic and Photoallergic are further divisions of the last branch. Irritant Contact Dermatitis is caused either by a Diaspora of physical irritants or a vast majority of chemical irritants. Metal working fluids like latex and kerosene and solvents like alcohol and acetone can be among the chemical irritants. Physical form of the anomaly may be caused due to very low humidity; in this aspect it is pretty close to eczema that is also aggravated by lack of humidifying agents.
The allergic Contact Dermatitis is not easily explicable in terms of the cause that might trigger it and medical fraternity perceives and defines it as an overreaction of the immune system to certain microscopic allergens and pollens. Having said this, they concur that there isn’t any conclusive theory on which such an assertion can be based. The third kind or the Photocontact Contact Dermatitis occurs when a mildly or severely malicious substance on the skin surface communicates with ultra violet light. This is the chief reason why this form of Contact Dermatitis appears only in places that are exposed to sunlight. Photoproduct related toxins are known to trigger the syndrome.
While the rash can appear right at the moment in Irritant Contact Dermatitis, it might appear in 1 to 3 days in Allergic Contact Dermatitis. Urticaria and blisters are also known to form in skin areas where there is a deemed contract with foreign substance. While the allergic form often creates an itching sensation largely, the irritant form can get painful beyond the endurance level. At this point, people often tend to believe it as eczema. Well, it’s not eczema for sure but if the lesions are scratched a lot then it can lead to further complications owing to sluicing of pus and development of wound over the surface.
The diagnosis related to Contact Dermatitis is more generally based on the look of the syndrome and the history of a person in relation to the syndrome. Allergy testing like patch testing is known to be the most widely acknowledged method to diagnose the disease and has been given a thumbs-up by the medical fraternity and medical associations. Patch testing is usually undertaken for patients who siphon Contact Dermatitis with chronic frequency.
It requires three visits. In the first visit, potential allergens are posted on the skin surface in patches. In the second visit, these patches are taken away (this visit often takes place 48 hours from the first visit but there is no hard and fast rule), the third visit is made further couple of days ahead to find if there is a delayed or procrastinated reaction. Patients are being asked to carry specific allergens that they think might have triggered some irritating response from the skin on testing.
There are many lines of treatment for Contact Dermatitis. Therapists believe that often doing just nothing to the area is a nice way to get freed from the ailment. However, if the rashes persist, it’s an effective remedy to apply lots of water on the surface. If the rashes do not die down yet then the doctors would prescribe you Corticosteroid skin creams and Antipruritic lotions. Wet dressings are also known to register a strong remedying impact on the skin. Tacrolimus ointment has its share of admirers too.
