Final answer:
Atopic dermatitis refers to a prolonged allergic response in the skin, characterized by dry, itchy patches. It is commonly known as eczema and is distinct from contact dermatitis, which is a type IV hypersensitivity reaction. Management often includes moisturizers, corticosteroid creams, and immunosuppressants.
Step-by-step explanation:
The condition described as prolonged allergic responses in the skin, also known as apoptotic dermatitis, refers to Atopic dermatitis. This is a chronic skin condition also commonly known as eczema. Atopic dermatitis is characterized by dry, itchy patches of skin, which may swell, flake, and sometimes bleed. It is not a type IV hypersensitivity reaction like contact dermatitis, which results from direct contact with allergens such as latex or poison ivy. Rather, atopic dermatitis is often associated with a family history of allergies and can be linked to asthma and hay fever.
Urticaria, also known as hives, is a different type of allergic reaction featuring red, itchy welts, and Anaphylaxis is a severe, potentially life-threatening allergic reaction. Contact dermatitis is an example of a type IV hypersensitivity reaction that occurs after re-exposure to an allergen, leading to an inflammatory reaction in the skin. Although it shares some characteristics with atopic dermatitis, such as skin irritation, it is different in its pathophysiology and management.
To manage eczema, patients may use moisturizers, corticosteroid creams, and immunosuppressants to alleviate symptoms.
