Home Skin conditions 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.

I. Definition http://www.skinsite.com/info_urticaria_pigmentosa.htm

Urticaria Pigmentosa I. Definition: Urticaria pigmentosa is an uncommon rash that usually affects the neck, arms, legs and trunk of children and young adults. The rash consists of reddish-brown spots that turn into hives when they are rubbed hard or scratched. Sometimes the spots will blister. II. Causes: The spots in urticaria pigmentosa contain a large number of mast cells (cells are the bodies building blocks). Mast cells are immune cells (cells that fight infection) that live in the skin. Mast cells make a substance called histamine. Histamine causes hives, itching, and flushing. We do not known why people with urticaria pigmentosa have abnormal collections of mast cells in the skin. III. Prognosis: Most children who develop urticaria pigmentosa before the age of five will have resolution of the condition by adolescence or early adulthood. When urticaria pigmentosa starts after the age of five, the abnormal collections of mast cells will sometimes involve the internal organs and the disease does not always go away. These patients need blood tests and other studies. IV.

Urticaria (Hives) I. Definition: Hives are itching red welts or small bumps that last for 15 minutes to several hours. They usually appear suddenly and leave no trace when they disappear. Crops of hives may appear several times a day, they may even last for weeks, sometimes longer. Hives are harmless except when they cause throat swelling; this is rare but requires immediate treatment. II. Causes: Hives can be caused by something taken internally, most often a medicine such as penicillin or aspirin. Sometimes foods cause hives; shellfish and strawberries are well-known examples. Hives are also sometimes caused by infection. Most of the time, we do not find the cause. III. Treatment: When treating hives, we try to find their cause. Medicine is prescribed to control the rash and itching. Hives are usually controlled with antihistamines. (Caution: antihistamines may cause drowsiness; if you feel sleepy, don't drive. Also do not drink alcohol.) Injections of epinephrine (Adrenalin) may be used for treating severe hives. Sometimes epinephrine-like medicines taken by mouth are used in combination with antihistamines.

dermatologie Urticaria INLEIDING Urticaria (urtica = brandnetel) is de medische naam voor netelroos of galbulten. Het is een zich in korte tijd ontwikkelende, vaak heftig jeukende uitslag van de huid, die begint met rode vlekjes en daarna in verdikte bleke plekken kan overgaan. De huidafwijkingen kunnen al of niet samenvloeien tot grotere vlakke plakkaten. In feite betreft het een vochtophoping in de bovenste laag van de huid doordat de kleine haarvaatjes in de huid zich verwijden (de rode fase) waarna door lekkage het vocht in de weefsels terecht komt (bleke fase). Eén zo'n plek noemen we een urtica of kwaddel; het ziektebeeld in zijn geheel heet urticaria. Deze reactie is in het algemeen wel vervelend, maar meestal niet van ernstige aard, omdat het proces zich vrijwel steeds na enkele uren weer herstelt. De aanvankelijk jeukende plekken trekken dan geleidelijk weg. Urticaria is een vaak voorkomende huidreactie.

Urticaria The diagnostic challenge of hives Richard J. Sveum, MD VOL 100 / NO 2 / AUGUST 1996 / POSTGRADUATE MEDICINE This is the second of five articles on allergy Preview : Patients who present with hives are often hoping their physician can tell them what caused the condition. In acute cases, that is often possible, but unfortunately, the majority of chronic cases are idiopathic. In this article, Dr Sveum puts the spotlight on urticaria. He stresses the importance of taking a careful medical history and describes treatment options. U rticaria is part of a more severe allergic reaction called anaphylaxis, in which hypotension or respiratory distress can be present. When a patient presents with flaring or reddened skin and wheals, prompt evaluation is needed. Once the physician is sure anaphylaxis is not occurring, the next step is to proceed with careful history taking. Urticaria, commonly known as hives, is a vascular reaction in the upper dermis, marked by the development of wheals on virtually any area of the body. Acute urticaria is defined as hives that last for less than 6 weeks (1); when the hives last for more than 6 weeks, however, the condition is considered chronic. Chronic urticaria can be particularly frustrating to diagnose and treat, since most cases are idiopathic. Fortunately, the condition can often be controlled with appropriate medical management.

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

URTICARIA Juan Guillermo Chalela, MD Jefatura de Dermatología. Escuela Colombiana de Medicina. Desde el punto de vista evolutivo la urticaria puede llamarse aguda, cuando tiene menos de seis semanas de evolución y crónica, cuando lleva más de ese tiempo. Hay una presentación que no se relaciona con el tiempo de evolución, es la llamada urticaria física o por contacto la cual se relaciona más con el uso de sustancias capaces de producir algo similar a una prueba de parche. ETIOLOGIA Las causas de la urticaria son innumerables y en muchas ocasiones es imposible lograr saber el por qué se presentó el cuadro. Las causas más frecuentes se analizan a continuación. Alimentos: aunque puede haber discusión sobre el papel de éstos en la enfermedad, en varias ocasiones se detectan algunos alergenos que los alimentos logran producir para desencadenar una respuesta de tipo urticariante. Los chocolates, la carne de cerdo, los mariscos, los derivados lácteos, los colorantes, las levaduras, las gaseosas negras y las sustancias con preservativos, pueden producir esta respuesta. Medicamentos: son la causa más común del proceso y son numerosas las drogas que lo pueden producir. La aspirina y los salicilatos ocupan el primer lugar pero, la penicilina, las sulfas, los esteroides, los narcóticos, los AINES y los medios de contraste son igualmente importantes.

Social Hygiene Handbook - 2nd Edition URTICARIA Dr. C.Y. LEUNG CHAPTER 6 1. DEFINITION Urticaria is characterized by transient itchy pale dermal swellings secondary to the release of histamine and possibly other vasoactive agents from mast cells. 2. AETIOLOGY The release of histamine, and possibly other vasoactive mediators from mast cells leads to a sudden increase in vascular capillary permeability allowing the escape of fluid from the circulation into the tissues. Mast cells may degranulate in response to a number of stimuli including physical, chemical, pharmacological and immunological. Vasodilatation, dermal oedema and a mild perivascular infiltration of lymphocytes and eosinophils are seen in a typical lesion of urticaria. However in a small number of patients repeated biopsies may show a predominance of neutrophils and eosinophils infiltrate and absence of endothelial damage, representing a late phase reaction. This picture would suggest that other cellular elements and mediators may operate in the pathogenesis of urticaria in some cases. 3. CLASSIFICATION OF URTICARIA

Urticaria www.StudentHealth.co.uk Urticaria is often referred to as nettle rash or hives. The disorder causes wheals var word = "wheals" document.write('') in the skin. The weals can be a few millimetres or several centimetres diameter, coloured white or red, often surrounded by a red flare, and usually itchy. Each wheal may last a few minutes or several hours, and may change shape. Wheals may be round, or form rings, a map-like pattern, or giant patches. Involvement of the face may cause swelling of the eyelids and lips. The wheals and swellings occur because of the release of chemicals, such as histamine, into the tissues. This causes small blood vessels to leak fluid into the skin. There are various different types of urticaria, which can be classed as "acute", meaning it has only been present recently (hours, days or a few weeks), or "chronic", meaning it has persisted for several months or even years. Wheals may not be present all the time, often being more noticeable at certain times of day or when hot. Cause People often associate acute urticaria with an allergic reaction. Typically, medicines such as antibiotics, or food, including even tiny amounts of fish, eggs, nuts or chocolate, are responsible. It depends on previous exposure to the material, and the development of an immune reaction to it.
