Dermatitis

Dermatitis is inflammation of the various levels of the dermis which is the second layer of the skin. The dermis contains sweat glands, blood vessels and nerves to provide sensations of pleasure, pain, pressure, itch, or temperature. The dermis is composed of tissue types of collagen, elastic tissue, and reticular fibers. Any rash or inflammation such as psoriasis, eczema, skin cancer, seborrhea, etc. is dermatitis. Specific types of dermatitis are as follows: allergic contact dermatitis which is a delayed hypersensitivity reaction involving allergens and antibodies, contact dermatitis is due to exposure to irritating chemicals or detergents, atopic dermatitis which is an allergic reaction that is accompanied by hay fever, asthma, and very dry skin.

Occupational Dermatitis

Hand eczema often results from a combination of causes, including genetic makeup, injury, contact with irritants and allergy. It is frequently caused or aggravated by work, when it is known as occupational dermatitis. Hand dermatitis is particularly common in industries involving cleaning, catering, metalwork, hairdressing, healthcare and mechanical work.Hand dermatitis varies in severity. It may affect the backs of the hands, the palms or both sites. Often it starts as a mild intermittent complaint, but it can become increasingly severe and persistent. The affected skin initially becomes red and dry, then progresses to itchy bumps and fluid-filled blisters, scaling, cracking, weeping and swelling. Bacterial infection can result in pustules, crusting and pain. Longstanding dermatitis at the ends of the fingers may result in deformed nails. Hand dermatitis can spread to affect other sites, particularly the forearms and feet.
