Abstract

Constitutional eczema (late atopic dermatitis) is a frequent condition: some 30% of the skin diseases seen by the GP involve constitutional eczema. A number of links with (external) factors have meanwhile been established. Patients with constitutional eczema often suffer from food allergy (over 60% of the children with the eczema) and many are allergic to airborne allergens (especially housedust mite allergen). The skin of patients with constitutional eczema has a diminished barrier function against irritants (soaps, acids, bases, water, detergents, biological juices (fruit, meat, fish, vegetables). In 90% of the patients with constitutional eczema the skin contains colonies of Staphylococcus aureus (in 5% of people without eczema). S. aureus can influence the eczema through exoantigens (so-called superantigens) and through conventional antigens that may evoke an IgE-mediated immune response. Emotional stress may influence the eczema. The close anatomical relationship between mast cells and nerve endings and between Langerhans cells and nerve endings suggest that the autonomous nervous system can modulate the immune system of the skin and consequently, the eczema. These factors should be taken into account in the treatment: red...Continue Reading

Atopic Dermatitis

Atopic dermatitis is a chronic inflammatory genetically determined disease of the skin marked by increased ability to form reagin (IgE), with increased susceptibility to allergic rhinitis and asthma, and hereditary disposition to a lowered threshold for pruritus.

CRISPR & Staphylococcus

CRISPR-Cas system enables the editing of genes to create or correct mutations. Staphylococci are associated with life-threatening infections in hospitals, as well as the community. Here is the latest research on how CRISPR-Cas system can be used for treatment of Staphylococcal infections.
