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

Joe suffers from a rare skin disease, Urticaria Pigmentosa, that effects only one in a half million people. Insect venom is one trigger for the unusual disease. In 2001, Joe nearly died from two ordinary bee stings before learning the medical frailty of his skin disease. Believe it or Not, Joe was stung twice in the same location four weeks apart. His wife, Diane, is credited with saving his life after the second bee attack. While driving with Joe dying in their minivan, Diane miraculously came upon a car wreck with an ambulance on the scene. Diane disregarded the police detour and drove to the accident scene. After rescue workers took one look at Joe, the ambulance transported Joe ahead of the intended accident victim to the closest hospital.

Allergy Capital Urticaria and Angioedema Hives (also known as urticaria or angioedema) look like mosquito bites. Although some unlucky individuals can have them every day for weeks, individual lumps usually go in minutes to hours. Most cases of hives are not due to allergy. Revised 1 February 2003 IMPORTANT The information provided is of a general nature and should not be used as a substitute for professional advice. If you think you may suffer from an allergic or other disease that requires attention, you should discuss it with your family doctor. What are hives? Hives (also known as urticaria) look like mosquito bites. They range from the size of a pinhead to that of a dinner plate. Although some unlucky individuals can have them every day for weeks, individual lumps usually go in minutes to hours. In most people, hives are not due to allergy. How common are hives? Approximately 1 in 6 people will develop hives some time during their life and are most common in children. They eventually disappear in most people. They may reappear following infection, when under stress or for no particular reason. Hives occur in the skin Underneath the lining of the skin, gut, lungs, nose and eyes are mast cells. These are designed to kill worms and parasites. Mast cells are like "land-mines", and contain "bags" filled with irritant chemicals including histamine. When these are released in small amounts, they cause local itch and irritation. In larger amounts, they will cause fluid to leak out of blood vessels, resulting in swelling of the skin. Occasionally, hives may not be itchy at all.

47. Hives Or Urticaria Are Skin Disorders Related  To Food Allergy  That Can Be So Hives are itchy red welts associated with swelling. Hives are food allergy until proven otherwise. http://www.nutramed.com/skin/skinhives.htm

Home Modular Nutrition Logon Skin Center Hives or Urticaria From the Book of Skin Skin Rescue Skin Nutritional Rescue Skin Rescue Starter Pack ... Skin Center Alpha Nutrition Hives or urticaria are common allergic reactions. They are itchy, elevated, red blotches of varying size that appear suddenly and disappear mysteriously after hours to days. Hives may be associated with dramatic swelling reactions; swelling of the lips, eyes, and ears can suddenly and grotesquely alter the appearance of an allergy victim. Marked swelling especially of facial tissues is referred to as angioedema and is often associated with urticaria. Swelling of the lips and tongue may occur immediately after eating a food and may be life-threatening because of airway obstruction. Foods and drugs are the common causes of hives. Some patients get hives occasionally only when they ingest a specific food or food additives. Other get hives as a chronic problem which can go-on for years. Most studies of chronic hives suggest a low % of food allergy causes usually because diet revision attempts were inadequate to reveal the hidden food causes. Acute Urticaria is Immediate Hypersensitivity The type I version of urticaria tends to occur in acute discrete attacks and may follow the ingestion of specific foods, over-the counter medications, or prescription drugs. Atopic children with eczema and rhinitis are prone to urticaria from food. Hives are associated with high IgE and occur usually as acute food reactions. Hives also occur as a feature of anaphylactic reactions. The itchy, erythematous welts, typical of acute urticaria can occur in any distribution in the body. Infants may develop facial wheals on contact with food. Adults often have a single bout of hives when they encounter an unusual or seasonal food or take a drug. Hives following a strawberry feed in the summer or after a eating prawns at a sea-food restaurant are typical examples.

Surrey Allergy Clinic Urticaria (Hives or "Nettle" Rashes) by Dr Adrian Morris Urticaria is a raised itchy and painful skin rash sometimes called a “nettle rash” or hives. There are two distinct types of urticaria: Acute urticaria is often caused by an allergy to food or medication and can last between several hours and six weeks. Chronic urticaria is diagnosed if the rash persists for six weeks or longer, the underlying cause is then usually not due to food allergies. What are the causes? Acute Urticaria The most likely cause of Acute Urticaria is an allergy due to exposure to pets, horses, latex rubber, food such as shellfish, nuts, egg and dairy products or bee and wasp stings. Allergies to medication such as antibiotics (penicillin, tetracycline, sulphonamides and cephalosporins), blood pressure pills (ACE inhibitors and diuretics), codeine and aspirin containing pain killers can cause acute urticaria. Sometimes viral infections such as glandular fever and hepatitis B, or bacteria (helicobacter, streptococci), fungal and parasitic infections can trigger urticaria. Allergic reactions to blood products, transfusions, xray contrast and vaccines have also been implicated. Papular urticaria is the medical term for “itchy bumps” or grouped urticarial lesions seen mainly in children and which follow insect bites from midges, fleas and mosquitoes. Chronic Urticaria The cause of Chronic Urticaria is much more difficult to identify. The role of true food allergy is hardly ever a significant trigger but food additives such as salicylate, sodium benzoate, colourings and nitrites may play a role. We often end up diagnosing

Hives (Urticaria) HOME Announcements After Hours Care Contact Us ... STUDENT AFFAIRS LINKS Description: About one in five people will experience hives at some time in their lives. Hives are intensely itchy welts that are pink-white and may vary from mosquito-bump size to large plaques many inches across. They can occur anywhere on the body. The swelling is due to leaky blood vessels under the skin. Both immunologic and nonimmunologic factors (see below) can lead to release of histamine and other vaso-active chemicals that destabilize the vessels. Note that hives come and go within twelve to twenty-four hours and often more frequently. A stationary rash that has been present for three to five days is not hives. Rashes that leave persistent marks also do not represent typical hives. Sometimes considered a variant of hives is the sudden appearance of a swollen eye, lip or tongue. The latter is called angioedema and can be life-threatening if it involves the tissues of your airway (tongue, epiglottis, larynx, lungs, etc.). There may be a family history of this disorder. Causes: In many cases an allergen has been ingested.

Home Information Sheets Information Sheets Urticaria and Angioedema Introduction Urticaria, often called "hives", refers to a skin eruption consisting of raised demarcated intensely itchy papules or weals. While urticaria involves dermal swelling, angioedema is due to oedema in the deeper subcutaneous and submucosal tissues, especially involving the palms of the hands, soles of the feet, head, and neck. Angioedema of the throat may cause respiratory obstruction in severe cases. Urticaria/angioedema has been arbitrarily defined as ‘Acute’ if it lasts less than 6 weeks, with more prolonged cases of relapsing skin swellings being labelled as ‘Chronic’. Up to 50% of cases of urticaria are associated with angioedema, and up to 25% of the population will develop one of these problems during their lifetime. Pathophysiology Tissues involved in urticaria/angioedema reveal dermal or subcutaneous oedema in association with a perivascular infiltrate of T-lymphocytes, macrophages, eosinophils and mast cells which may be sparse and fleeting in acute cases or more extensive in chronic urticaria. The swelling and itch seen in urticaria/angioedema is due to mast cell degranulation. The triggers include a variety of factors (Table 1). However, in up to 50% of cases of acute and chronic urticaria/angioedema, no cause is identified. Some physical urticarias involve structural modification of the IgE molecule by various physical factors, and are IgE-mediated.

If you feel that you have a skin problem, please see your doctor. Urticaria is a common skin disorder that is characterized by the spontaneous development of swollen pink or red itching areas called "hives", "whelps", or "wheels". These are produced by the leakage of a liquid portion of the blood through the walls of tiny blood vessels into the skin or mucous membranes of the body. Urticaria usually comes on abruptly, with large numbers of "hives" in repetitive crops. A "hive" can be a few inches to several inches in size and when individual "hives" join together they can even cover an entire body area. An individual "hive", from a particular crop, will usually disappear after a few minutes to several hours without leaving any permanent changes in the skin. Typically, most individuals, have a single attack of urticaria that lasts only briefly - for several days. This is referred to as ACUTE URTICARIA. Unfortunately, some cases of urticaria may also persist and "come and go" with attacks being intermittent or continual for years. When urticaria lasts more than three months, we refer to that type as CHRONIC URTICARIA.

Urticaria and Angioedema Acute Urticaria Chronic Urticaria Physical Urticaria Treatment Hives are reddish pink swellings or "wheals" that occur in crops on any part of the skin. Each wheal lasts a few hours before fading away, leaving no trace. New hives may continue to develop as old ones 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 are usually very itchy, but may also burn or sting. A natural chemical substance called Histamine is released from cells called "mast cells" which are found in the skin. A number of different things including allergic reactions, chemicals in foods, or medications can cause histamine release. Hives usually disappear within a few days to a few weeks. Occasionally, a person will continue to have hives for many years. When hives form around the eyes or lips, the tissue may swell excessively. The term Angioedema is used to describe this type of swelling. Acute Urticaria Hives are classified according to how long the attacks last. The term "acute urticaria" is used for hives lasting less than six weeks. With this type of hives, the cause can usually be identified and eliminated. The most common cause of hives are certain foods, drugs or infections. Insect bites and certain internal diseases may also be responsible. Other causes can be physical stimuli, including pressure, cold and sunlight.
