Camp Discovery Contact Us Kids' Connection Medical Web Guide ... Skin Cancer Updates Urticaria - Hives Hives , or "wheals", are pale red swellings of skin that occur in groups on any part of the skin. Urticaria is the medical word for hives. Each hive lasts a few hours before fading without a trace. New areas may develop as old areas fade. They can vary in size from as small as a pencil eraser to as large as a dinner plate and may join together to form larger swellings. Hives usually are itchy, but may also burn or sting. Hives are formed by blood plasma leaking out of small blood vessels in the skin. This is caused by the release of a chemical called histamine. Histamine is released from cells called "mast cells" that lie along the blood vessels in the skin. Allergic reactions, chemicals in foods, or medications can cause histamine release. Sometimes it's impossible to find out why hives are forming. Hives are very common - 10-20 percent of the population will have at least one episode in their lifetime. Most episodes of hives disappear quickly in a few days to a few weeks. Occasionally, a person will continue to have hives for many years.

ACAAI Homepage About ACAAI Bulletins Information for: Patients Physicians Employers News Media Urticaria Urticaria, commonly known as hives, usually strikes suddenly. First the skin itches, then it erupts into red welts. The itching may be severe, keeping people from working or sleeping. It's a distressing disorder which affects an estimated 20 percent of the population at one time or another in their lives. What is urticaria? Most cases of urticaria are acute, lasting from a few hours to less than six weeks. Some cases are chronic, lasting more than six weeks. The welts may appear in one place, disappear after a short time, then erupt at another spot, then another. They are made worse by scratching. Each individual hive lasts no more than 24 hours. What kinds of things can trigger attacks of urticaria? Bouts of urticaria have been traced to such triggers as infections, drugs (including aspirin), certain foods and additives, cold, sun exposure, insect stings, alcohol, exercise, endocrine disorders and emotional stress. In some people, pressure caused by belts and constricting clothing causes eruption. Urticaria may be a response to infection including the common cold, strep throat and infectious mononucleosis. In the urticaria-prone person, these triggers cause the body to release chemical mediators, including histamine, from cells. Histamine (which causes itchy, runny noses and watery eyes in hay fever sufferers) dilates the walls of blood vessels, allowing fluids to leak out into the surrounding tissues. Swelling and itching are the result.

Site map Search: Home Reactions Urticaria Urticaria refers to a group of disorders in which red patches and weals occur in the skin. The release of chemicals from mast cells in the skin causes small blood vessels to leak and results in tissue swelling. The weals can be a few millimetres or several centimetres in diameter, coloured white or red, often surrounded by a red flare, and frequently itchy. Each weal may last a few minutes or several hours, and may change shape. Weals may be round, or form rings, a map-like pattern or giant patches. The surface weals may be accompanied by deeper swelling of eyelids, lips, hands and elsewhere. The swelling is called angioedema . Angioedema may occur with or without urticarial weals (10%).

Lanternier, MD and Karen Brannon, MD Department of Family Medicine, University of Iowa College of Medicine, and Private Practice, Muscatine, Iowa Peer Review Status: Externally Peer Reviewed by Mosby Overview . Urticaria is a common disorder that affect 15%-20% of the population at some time. Urticaria is characterized by a transient, pruritic, patchy eruption that consists of lightly erythematous papules or wheals with raised borders and blanched centers involving the superficial skin layers; involvement of the deeper layers and/or the submucosa is called angioedema . Lesions vary considerably in size, from 2 mm to over 30 cm and may be circular or irregularly shaped. The most common site for urticaria is the trunk, although lesions may occur on any part of the body. Urticaria has been divided into two major groups: Acute urticaria . Defined as hives persisting for less than 4 to 6 weeks (usually two to three days). It occurs with a higher incidence in atopic individuals. Commonly identified causes include foods, drugs, and infections but in over half of patients there is no identifiable cause. Angioedema . Acute attacks are manifested as large irregular areas of subcutaneous swelling. Cause is similar to urticaria but may also include hereditary angioedema (see below) or, commonly, ACE inhibitors

In UK about 1% of the population will suffer from urticaria during their lifetime. Out of this appox. 25 % of the patients would be of chronic urticaria. Chronic urticaria presents in a variety of presentation. About 5 % are shown to be Reactive to the food allergens . 5% may have urticarial vasculitis Physical urticaria is seen in about 35%-40 %, while aprox. 50 % have so called Idiopathic Urticaria Physical Urticaria - in this most striking is dermographism. A useful procedure in confirming the diagnosis of dermographism is challenge test with a caliberated dermographometer, which measures the pressure being applied to the skin. Other common physical urticarias are cold urticaria, cholinergic urticaria and solar urticaria. Cold urticaria can be tested by appliing ice to the skin., cholinergic urticaria can be seen by exercising the patient or bathing in warm water and solar urticaria can be tested by solar simulator lamp. Patients with physical urticaria need no firther investigations. The patients shold be informed of the condition for which the average time cource os 2-3 years. and during this time the main therapeutic approach is to cover the patient with H1 antihistamine. Very little is known about the pathogenesis of the physical urticaria.

Site map Search: Home Arthropods Papular Urticaria Papular urticaria most commonly affects children but adults may also be affected. Crops of very itchy red bumps, 0.2 - 2 cm in diameter, appear every few days. Sometimes each spot develops a fluid-filled blister up to one centimetre in diameter. They are most often on the legs and other uncovered areas such as forearms and face but sometimes they are scattered in small groups all over the body. It is difficult not to scratch the spots, which become crusted and may get infected - they are then pussy and sore. Sometimes one new spot provokes all the old ones to come up again and itch intensely. The spots seem to remain for a few days to a few weeks and can leave persistent marks or scars, especially if they have been scratched deeply. Papular urticaria is more common in spring and autumn. It may clear up on holiday or on moving house. One or several members of the family may be affected. Occasionally the eruption can clear up for years and then recur unexpectedly. It is not associated with any internal complaint and is never a serious disease. Papular urticaria is thought to be an allergic reaction to insects in the environment. Often after a few years the person becomes desensitized to these insects and the reaction dies down. A bite isn't usually noticed and it is thought that the reaction can occur simply from skin contact with parts of the insect such as its faeces and eggs - this accounts for spots in unexpected places. The most common identified causes are insects that live on cats and dogs, such as fleas and mites.
