Final answer:
a. Chronic urticaria involves itchy, raised areas of skin and is often treated with antihistamines, anti-inflammatory drugs, and avoidance of known allergens.
b. Diagnosis or workup may include skin testing to identify the causes of allergic symptoms.
c. Treatment (Tx) is managed with moisturizers and corticosteroid creams.
Step-by-step explanation:
Chronic urticaria is a condition characterized by recurrent hives, which are itchy, raised areas of skin typically associated with allergic reactions. Signs and symptoms of chronic urticaria include swelling, redness, and itchiness. The workup for chronic urticaria may involve skin testing for common allergens using a pr*ck-puncture skin test (PPST) or an intradermal test. These tests help to identify the cause(s) of a patient's allergic symptoms and are essential in diagnosing type I hypersensitivities.
The treatment for chronic urticaria often includes antihistamines, anti-inflammatory drugs, and avoiding known triggers such as certain foods (like shellfish and peanuts) or environmental factors related to seasonal allergies. Contact dermatitis and delayed-type hypersensitivity reactions are important to consider during diagnosis and workup. In some cases, such as eczema, treatment may involve moisturizers, corticosteroid creams, and immunosuppressants. It is important for patients to manage symptoms with a healthcare provider's guidance.
