In severe cases, large areas of the face and trunk can be affected. The cause is uncertain, but may be due to colonisation with lipophile yeast fungi such as pityrosporum ovale. The best treatment is with shampoos containing tar, selenium disulphide, zinc pyrithion, salicylic acid and imidazol (e.g. bifonazol, ketoconazol). In the face and on the body, creams with imidazols such as bifonazol, clotrimazol, ketoconazol or also substituted pyridon ciclopirox should initially be used.

The risk of contracting atopic dermatitis is 30 % where one parent is already a sufferer, and 60 % where both parents are sufferers. A congentital predisposition is found in about two-thirds of atopic dermatitis patients. The initial symptoms appear in 80 % of patients by the time they reach the age of two. It is less common for the illness only to appear in adulthood. Atopic dermatitis is a skin condition with clustering in families. It frequently reacts pathologically to environmental factors. Patients with atopic dermatitis tend to suffer from allergic rhinoconjunctivitis (allergic cold and allergic conjunctivitis) and allergic asthma. This family predisposition is the expression of an atopic reactivity, which is believed to be based on polygenic factors. Polygenic means that a number of different genes are …
