Eczema:
Dermatitis is a general term encompassing various
inflammatory skin conditions. It is characterized
by itching, redness, thickening and scaling of the
skin and skin eruptions.
The most common form of dermatitis is Atopic
Eczema, a general allergic, hyper-sensitivity to
allergens.
Although its underlying cause is unknown, Atopic
Eczema appears to be an excessive response of the
body's immune system to allergens.
Allergens enter the skin and activate the cells of
the immune system present in the skin.
These cells on activation release mediators of
inflammation such as histamine and prostaglandins.
The resulting reaction results in the itching,
redness and skin eruptions commonly experienced in
patients with Eczema.
In
more severe or chronic cases, Eczema can also
cause scaling and thickening of the skin.
Eczema can be caused by:
-
Contact with substances that chemically
aggravate the skin like detergents, soaps,
engine oils, strong chemicals, etc.
-
Stress, dry weather or, hot or cold
temperatures.
-
Environmental allergens.
Eczema is usually treated by removing known
allergens, preventing the skin from becoming dry
and utilizing steroid creams or antihistamines.
