Contact dermatitis is a skin disease. It is usually a skin lesion that occurs after the skin contacts external irritants. This lesion can cause skin damage, mainly erythema, swelling, papules , and blisters. In severe cases, bulla will appear, which has a very great impact on the skin. Regarding contact dermatitis, many people will confuse it with allergic dermatitis.
In order to better identify this type of disease, everyone should learn some medical knowledge by themselves in their daily lives. This is not only beneficial to themselves, but also more or less helpful to the people around them. So, what are the causes of contact dermatitis? If you have contact dermatitis, how can you use Western medicine to diagnose and treat it? Learning these 3 points may help you easily deal with them.
1. What are the causes of contact dermatitis?
If you want to figure out the cause of contact dermatitis, you must first know that contact dermatitis mainly includes two major categories: one is primary stimulation, and the other is allergic reaction. Therefore, contact dermatitis also includes allergic dermatitis.
Generally speaking, dermatitis caused by primary stimulation is usually related to some irritants. For example, in daily life, if people accidentally contact paint, chemical reagent and other irritants, it will cause an inflammatory reaction in the skin. This is a typical contact dermatitis.
In addition, for skin diseases caused by some allergens, symptoms such as redness, swelling, itching and other symptoms of the skin throughout the body within 12 to 48 hours, which is allergic dermatitis. Therefore, it is best not to confuse the two different mechanisms of dermatitis.
2. How should contact dermatitis be diagnosed?
Diagnosing contact dermatitis is actually not too difficult. At present, some medical testing methods can be used to differential diagnosis of contact dermatitis. If the index of immunoglobulin in the serum has increased, then in general, it is not contact dermatitis, but allergic dermatitis caused by allergic reactions, which can also be understood as dermatitis not caused by external stimulation.
Of course, if you are diagnosing this type of dermatitis, you should also find out whether the patient has been exposed to irritants or allergens before the dermatitis occurs. If there are related behaviors, it is not too difficult to diagnose.
3.How does Western medicine treat contact dermatitis?
The treatment of contact dermatitis mainly requires the following principles:
First, pay attention to actively seeking allergens. That is, when asking the patient, you should figure out what items the patient is allergic to, so that you can prescribe the right medicine;
Second, you should pay attention to avoid unnecessary stimulation, especially some people's skin is more sensitive and should not accept stimulation such as hot water and strong light. So it is better to have less contact in normal times and try not to cause trouble to your skin;
Third, you should pay attention to local treatment of the skin. For the acute stage of contact dermatitis, local application of drugs is mainly used. For the subacute or chronic stage, corticosteroid hormone ointment can be used, and dermatitis-related complications should also be actively treated. In short, the treatment of dermatitis requires a process. During this process, don’t be impatient and respond step by step to turn danger into safety.
