Atopic eczema - Atopic dermatitis in infants (Paediatrics)

Very low urgency
--

This is an inflammatory, chronic, recurrent skin condition whose sebaceous glands increase oil production. It particularly affects children who are less than one year old. It is included in the cutaneous eccema group.

There are a lot of different factors that condition its appearance: genetic components, allergic predisposition, infectious causes, psychological causes.

It manifests with red, scaly, irritated and itchy skin, especially in the cheeks, elbows and knees. In many cases, is associated with cutaneous injuries by scratching the area that end up infecting.

Diagnosis is suspected through a clinical questioning that makes a history of atopy or allergies (including family history) come to light and also by examining the lesions.

The outbreaks will be controled with corticosteroids, antihistamines. If there is a local infection, antibiotics may be used.

It is recommended for the skin to be looked after with a gentle cleanser, appropriate creams and by avoiding sweat. The causes of the outbreaks should be avoided once they are known, as well as the smallpox vaccine as it is a potential risk.
