In order to know the meaning of the term dermatitis, it is necessary, first of all, to discover its etymological origin. In this case, we can establish that it is a word of Greek origin, since it is the result of the sum of two components of said language:
-The noun "derma, dermatos", which can be translated as "skin".
-The suffix "-itis", which is used to indicate "inflammation."
Dermatitis is an inflammation that affects the skin , the largest organ in the body. Dermatitis can present in different forms and exhibit various characteristics that give it less or greater severity.
Simple dermatitis is a skin rash. An allergic reaction, an infection or a systemic disease are possible causes of such dermatitis, which may be accompanied by itching, fever and other disorders.
Contact dermatitis , on the other hand, is known as an irritation that occurs in a localized sector of the skin, caused by the action of an external agent. It may be due to an irritant substance or an allergen . To reduce or eliminate symptoms , it is possible to wash the area with soap and water, apply an acid solution and, in some cases and according to medical indication, take antihistamines.
The face, scalp, torso, and the folds in the area of the knees and elbows can be affected by atopic dermatitis , a very common skin disorder. Although its origin is not clear, this dermatitis is linked to immune system problems, genetic causes and environmental factors. Itching, redness of the skin and the appearance of blisters are part of the clinical picture of atopic dermatitis, whose treatment may include the administration of drugs, cosmetic actions and changes in diet .
Dermatitis herpetiformis and seborrheic dermatitis are other types of dermatitis that can affect humans for different reasons.
Specifically, regarding seborrheic we can establish that it is chronic and that it is identified because the person who suffers from it has both peeling of the skin and areas of the body that are red and itchy. Typically, these symptoms affect parts such as the chest, scalp, genitals, and face.
Likewise, we cannot forget perioral dermatitis, which causes small bumps with pus to appear around the mouth. It is unknown what causes it, although it is considered that one of the reasons it arises may be the use of certain creams and even the inappropriate use of aerosols, for example.
