Urticaria


There are many different types of Urticaria and is more commonly known as Hives or nettle rash because it is characterised by raised pink welts that appear on the skin in response to an allergic reaction that involves the release of histamine, bradykinin, the slow reactive substance of anaphylaxis, and kallikrein as vasoactive mediators derived from either mast cells and basophils or other immunologic mechanisms that involve the IgE mediated hypersensitivity response. There is an increased number of eosinophils in the blood initially near the inflammation site that is considered an allergic response.
Under this heading is Giant Urticaria, Hives and Angioneurotic Oedema which can be differentiated in the following way.
Urticaria is a localised response in the superficial dermis and can be more noticeable at either certain times of the day when the body temperature may be raised or as a person becomes emotional. As the swelling increases it becomes itchy.
Angioedema is a deeper condition involving more tissue deeper within the dermis and subcutaneous levels. It may also involve the mucous membranes. The oedema is much more pronounced as more layers of the skin are involved. If the swelling which is more pronounced in this condition.
