Dermatitis - a syndrome is an inflammatory skin reaction to various stimuli. Distinguish contact dermatitis and drug reaction.

 General Information
Distinguish contact dermatitis and drug reaction. Contact dermatitis occur when the direct effects of the stimulus on the skin, toksidermii foreign substances penetrate into the body, causing a number of changes, one manifestation of which is dermatitis. For example, if the inflammatory reaction in the skin with the cream occurred with any drug substance that is contact dermatitis, and if the same material received in the body through the intestines (tablets or with food), and rash occurred - a drug reaction.
In addition, such diseases include dermatitis is seborrheic dermatitis (dandruff, acne, acne pimples), atopic dermatitis (allergic) dermatitis herpetiformis, eczema, and others. In this article, we will examine a few of them.

Causes of Dermatitis
Irritants that cause dermatitis, may have physical, chemical or biological nature.
There are so-called obligate irritants that cause dermatitis easy for each person. These include friction, pressure, radiation and temperature effects, acid and alkali, some plants (nettle, fraxinella, acrid buttercup, spurge). We all know what burns and frostbite, blisters, every once in my life, "burned" nettle. Manifestations and severity of dermatitis are determined by a simple strength and duration of exposure factor. Simple contact dermatitis symptoms appear immediately or shortly after the first contact with an irritant and lesion area corresponds to the area of ​​contact. Sometimes it is possible chronic dermatitis with prolonged action of the stimulus.
Optional stimuli cause inflammation of the skin only in individuals with hypersensitivity to them. We are talking about diseases such as allergic contact dermatitis and atopic (allergic) dermatitis. Number of elective stimuli (sensitizers) is enormous and growing.
Allergic contact dermatitis, in contrast to the simple, does not develop immediately after exposure to the stimulus, and the first contact. To allergic reaction (sensitization) formed require up to several weeks from the first contact. Then repeated contact dermatitis develops. Inflammatory skin reaction does not correspond to the intensity of the stimulus, which does not cause any changes in people without allergies. The area of ​​skin changes may extend beyond the contact.
Atopic dermatitis - a very complex disease, a chronic inflammatory skin lesions of allergic nature. It may cause a very few, and even many factors - allergens, and thus not only contact but also received by inhalation (pollen, dust) or food (food allergy). It also includes atopic diseases bronchial asthma, allergic rhinitis and others. Predisposition to atopy is transmitted genetically.
Atopic dermatitis usually develops in early childhood. Often with age manifestation of the disease subside or disappear altogether.

The symptoms of dermatitis
Simple dermatitis occurs acutely or chronically. For acute dermatitis is characterized by bright inflammation, accompanied by itching, burning, pain, and sometimes - blistering and areas of necrosis, leaving scars.
Chronic dermatitis appear stagnant edema, cyanosis, thickening of the skin, lichenification (desquamation), cracked reinforced keratinization, sometimes atrophy of the skin.For acute manifestations of allergic contact dermatitis and atopic dermatitis are also characterized by a bright red skin with marked edema. Further, bubbles may appear and even blisters opened and leaving oozing erosion (Moisture). Decaying leaves inflammation peel and flake.

What you can do
The appearance of dermatitis better to consult a doctor and not to self-medicate. In the treatment of simple contact dermatitis is the main termination of the stimulus. Often patients, understanding the cause of disease, cope with it themselves.However, there are cases (for example, severe chemical and thermal burns, frostbite) when the intervention of a doctor is necessary.

What can a doctor
In the treatment of dermatitis can help you dermatologist and allergist. If necessary, you may be referred to a gastroenterologist and other specialists.
Treatment of allergic contact dermatitis is assigned to a dermatologist and reduced primarily to identify the allergen. You ask in detail about the lifestyle, occupational hazards, cosmetics that you use, and others. With the exclusion of the allergen contact dermatitis symptoms usually disappear.
Much more complicated treatment of atopic dermatitis. This disease should be treated by qualified allergist. Applied antihistamines (such as oral, and ointments), glucocorticoid drugs, allergen-specific immunotherapy (SIT).

Preventive measures
Observe safety in the workplace and at home. If you had once been allergic dermatitis and the cause is known, try to avoid contact with the relevant allergen.
The main directions of profilaktikiatopicheskogo dermatitis is adherence to diet.
