The terms "dermatitis" and "eczema" are often used interchangeably. Dermatitis can be "acute" or "chronic" or both. Acute eczema refers to a rapidly evolving red rash which may be blistered and swollen. Chronic dermatitis refers to a longstanding irritable area. It is often darker than the surrounding skin, thickened (lichenified) and much scratched.
Types of dermatitis include the following:
Atopic dermatitis
Contact dermatitis
Seborrheic dermatitis
Nummular dermatitis
Diagnosis of dermatitis
Individuals react to a substance days after exposure; this is called a Delayed Hypersensitivity Reaction. This delay in reaction time makes identification of the causative allergen very difficult.
Treatment of dermatitis
Topical steroid creams are the mainstay of the acute treatment. Get control with a potent steroid and wean to a less potent steroid cream. Only use dilute hydrocortisone (0,5%) on the face and skin creases.
Avoid offending agent(s) (usually cosmetics, cold creames, etc).
Wear soft smooth cool clothes; wool is best avoided.
Protect your skin from dust, water, solvents, detergents, injury.
Mild steroid cream may be indicated over the affected area.
