Children bear the greatest burden of World Allergy Organization calling on international and national allergic deseases. The most common allergic conditions in health care policy makers to address early identification of children are food allergies, eczema, and asthma.

Between 1961 and 2000, it caused 120 options in a population heavily exposed to honeybee stings fatalities in Switzerland – an average of three every year such as beekeepers and their family members.

Urticaria Classification and external resourcesICD-10L50.ICD- 9708DiseasesDB13606MedlinePlus000845eMedicineemerg/628 MeSHD014581Urtic aria (or hives) is a skin condition, commonly caused by an allergic reaction, that is characterized by raised red skin wheals (welts). It is also known as nettle rash or uredo. Wheals from urticaria can appear anywhere on the body, including the face, lips, tongue, throat, and ears. The wheals may vary in size from about 5 mm (0.2 inches) in diameter to the size of a dinner plate; they typically itch severely, sting, or burn, and often have a pale border. Urticaria is generally caused by direct contact with an allergenic substance, or an immune response to food or some other allergen, but can also appear for other reasons, notably emotional stress. The rash can be triggered by quite innocent events, such as mere rubbing or exposure to cold.

Urticarial disease is thought to be caused by the release of histamine and other mediators of inflammation (cytokines) from cells in the skin.

  • Hymenoptera Sting Challenge of 348 Patients Relation to Subsequent Field
    Hymenoptera sting challenge of 348 patients: Relation to subsequent field stings Henk K. van Halteren, MD," Peter-Willem G. van der Linden, MD, PhD, b Sjaak A. Burgers, MD, PhD, c and Anton K. M. Bartelink, MD, PhD a Amersfoort, Haarlem, and Utrecht, The Netherlands' Background: Patients with a history of a serious anaphylactic reaction after a Hymenoptera sting are usually given venom immunotherapy. Because the natural history of Hymenoptera sting anaphylaxis is often of a declining severity, there is a chance of overtreatment. Objective: Identification of patients at risk for a future anaphylactic reaction may reduce the number of patients who need venom immunotherapy. Methods: We investigated the relation between the grade of hypersensitivity to an in-hospital sting challenge and the reaction to a subsequent accidental field sting. From 1982 through 1992, 348 patients" with mild or no symptoms after a sting challenge were not given venom immunotherapy. All patients were asked by letter whether they had experienced a subsequent field sting. In case of" a sting, the severity of the reaction was further evaluated. Results: Information could be obtained from 327patients: 129 had been re-stung, and 110 of them had only had a local reaction. Thirteen patients had experienced mild systemic symptoms, and six patients had experienced serious manifestations. In two of the latter group hypotension was observed. Conclusion: In 95% of patients with a previous anaphylactic reaction, the result of the in- hospital sting challenge provided a good prediction of tolerance to a subsequent Hymenoptera field sting. (J Allergy Clin Immunol 1996;97:1058-63.) Key words: Sting challenge, Hymenoptera, immunotherapy, anaphylccris Most stings by Hymenoptera species only lead to a local reaction: redness, swelling, itching, and Abbreviation used pain.

  • Insect Sting Allergy David F
    Med Clin N Am 90 (2006) 211–232 Insect Sting Allergy David F. Graft, MDa,b,* aAsthma and Allergic Diseases, Park Nicollet Clinic, Minneapolis, MN, USA bDepartment of Pediatrics, University of Minnesota Medical School, Minneapolis, MN, USA The study of allergy to insect stings holds a unique position in the field of allergy, and because of the usually singular and notable times of exposure, it serves as a model for the development, natural history, and treatment of al- lergic phenomena. The death of King Menes of Egypt shortly after a wasp sting is often cited as one of the earliest historical examples of anaphylaxis [1]. Soon after the concepts of anaphylaxis were defined by Portier and Richert in 1902 [2], generalized reactions to insect stings were recognized as hypersensitivity phenomena [3]. Ten years later, Braun [4] described a typ- ical patient with insect sting sensitivity and his use of insect venom for diag- nosis and treatment. Although this initial treatment used the posterior one eighth inch of the insect to increase the yield of venom, that stipulation was later ignored and for decades, immunotherapy with whole-body extract was used for the treatment of patients with insect sting reaction [5]. In the 1950s and 1960s, events occurred that eventually led to the development of venom immunotherapy (VIT). Loveless and Fackler [6] reported the successful di- agnostic and therapeutic use of extracts of venom sacs. Bernton and Brown [7] and Schwartz [8] independently found that whole-body extract skin tests did not discriminate insect allergic patients from subjects with no history of generalized reactions.

  • Insect Stings Is Systemic and Severe
    Insect Sting Allergy – The Facts Anyone who is stung by a bee or wasp is likely to suffer a painful swelling at the site of the sting. For most people, the sting is not dangerous. Some people also experience an allergic reaction to the venom. For most of these people, the allergic reaction is mild resulting in swelling at the site of the sting. But for a small minority, an allergic reaction to an insect sting can be systemic – that is, affecting parts of the body away from the site of the sting. Systemic allergic reactions are sometimes severe and potentially life-threatening – a condition known as anaphylaxis. If you are in this category, you may find the prospect of being stung very frightening but be assured that there are steps you can take to reduce the risk to yourself. This involves getting medical advice, carrying prescribed medication at all times, and taking precautions to avoid being stung. This Factsheet aims to answer some of the questions you may have if your allergy to insect stings is systemic and severe. Our intention is to help you to minimise risks. The information in this Factsheet includes brief medical references, which are given in brackets. Full references to these documents are listed at the end of the Factsheet. Who is at risk? Anyone can become allergic to an insect sting. People who have other allergies, such as hayfever or food allergies, are not at increased risk of having a severe allergic reaction to an insect sting (Krishna et al. 2011). You are more at risk of severe allergic reactions to insect stings if you have frequent or multiple stings.
