Atopic dermatitis, eczema, urticaria ... Allergic skin manifestations are numerous. Although data are lacking to evaluate the evolution of this problem, the available figures show a boom in this phenomenon.
Just like other atopic manifestations (rhinitis, food allergy ...), skin allergies are increasing. Focus on these French who are bad in their skin.
Atopic dermatitis: more than one in ten children affected Skin allergies Atopic dermatitis or atopic eczema is an inflammatory skin disease, often of allergic origin. It affects the infant preferentially and results in a dry skin. Increasing over the past twenty years, this disorder is affecting preferentially developed countries and populations with a high standard of living. An observation which is an argument in favor of the hygienist theory, according to which common pediatric infections 1 confer a certain protection against allergies and their absence a greater sensitivity.
Experts also consider that at least 15 to 20% of the population has developed an acute outbreak of urticaria during its lifetime 4. These manifestations, which appear to be in half of the cases of allergic nature, would determine 1 to 2% dermatology and allergology consultations.
The most common causes of these allergic urticaria are represented by food (eggs, fish, pork, milk, crustaceans, tomatoes, strawberries, chocolate ...) and drugs (penicillin, non-steroidal anti-inflammatory drugs, inhibitors of conversion enzyme ...). The drug allergies seem underestimated because they do not always give very typical cutaneous reactions. In the survey of the French Society of Dermatology, 7.6% of French respondents said they presented this type of allergy 3.
However, contact urticaria can also be observed after sensitization to latex, hair products, cosmetics or industrial products.
