Atopic eczema - Atopic dermatitis in non-lactating child (Paediatrics)

Very low urgency
--

Inflammatory, chronic, recurring skin condition in which the sebaceous glands increase oil production. It mainly affects children under the age of one year. It belongs to the group of cutaneous eczemas.

There are many different factors that determine its appearance: genetic components, allergic predisposition, infectious causes, psychological causes.

It is characterised by red, scaly, irritated and itchy skin, especially on the cheeks, elbows and knees. In many cases, it is associated with skin injury due to scratching, which leads to infection.

Diagnosis is suspected by a clinical interview that reveals a history of atopy or allergies (including family history) and by examination of the lesions.

Outbreaks are controlled with corticosteroids, antihistamines and immunomodulators. If there is a local infection, antibiotics may be used.

It is recommended that the skin is cared for with a gentle cleanser, appropriate creams and by avoiding perspiration. The causes of outbreaks should be avoided once they are known, as should the smallpox vaccine, which poses a potential risk.
