Insect bites and stings: managing allergic reactions.

This article concerns itself with three common reactions (local, toxic and anaphylactic) resulting from insect or arthropod bites and stings. A local reaction consists of sharp, localized pain followed by a reddening at the site, which usually resolves itself in 24 hours. A toxic reaction may include gastrointestinal symptoms, fever, headache, dizziness or convulsions, often following an episode of multiple stings. An anaphylactic reaction may be mild (hives, itching) or severe (systemic reactions including airway and cardiovascular symptoms). Even though most bites and stings are not serious, nurse practitioners should be aware of potential death resulting from insect sting allergy. They should teach hypersensitive patients, or patients with a history of a systemic reaction to any agent, about prophylactic measures. Tables showing the characteristics of insects that cause cutaneous lesions in humans, and measures necessary to decrease the risk of being stung, can be used as learning tools to prevent insect sting allergy. Because of the rapid onset of anaphylaxis, life-saving measures include awareness in persons who are hypersensitive, emergency preparedness and preventing bites and stings from occurring.

Bites and stings of Hymenoptera, caterpillar and beetle.

Insects compose a very large group of creatures that bite or sting but only a few are truly venomous in the sense that they inject a venom into human victims. Anaphylaxis from a Hymenoptera sting is the most serious reaction from this group and is estimated to account for approximately half of the annual fatalities from venomous bites and stings in the United States. Epinephrine, Benadryl, steroids, hyposensitization, local tissue management and symptomatic and supportive care are discussed.

[Recording of venomous bites and stings by National Information Systems in Brazil].

This paper highlights the epidemiological surveillance of venomous bites and stings according to four national information systems: SINAN (National Databank of Major Causes of Morbidity), SINITOX (National Information System on Poisoning), SIH-SUS (Hospital Information System of the Unified Health System), and SIM (Mortality Information System). The authors conclude that each information system has specific characteristics and addresses different demands. Although they contain large amounts of data, even if combined they fail to reflect the real magnitude of disorders caused by venomous bites and stings in the country.

[Round Table: Urticaria caused by arthropod bites and stings (excluding Hymenoptera)].

Adverse reactions to arthropod bites (hymenoptera excluded) can be faced with systemic reactions and local reaction. Among the numerous families of arthropods the species most commonly responsible are mosquitoes,. flea, horsefly and tick. In this article we explain the characteristics of reaction caused by arthropods and the mechanisms proposed. An IgE mechanism is incriminated in severe anaphylactic reactions. Various mechanisms have been proposed for local reactions. In order to know the incidence of sensitization and cross-reactivity with other arthropods, we have done a study where we have found that 31% of patients with reaction to mosquito bite had sensitization to Aedes communis and 53% of this group also had sensitization to other arthropods, probably due to a cross-reactivity.

Treatment of imported fire ant stings with mitigator sting and bite treatment--a randomized control study.

OBJECTIVE: To evaluate the efficacy of the commercially available product Mitigator Sting and Bite Treatment in reducing the pain after imported fire ant stings. METHODS: Twenty-four volunteer subjects were exposed to imported fire ant stings on both fore-arms. The subjects received Mitigator paste on 1 arm and calamine lotion on the opposite arm, in a blinded manner, from 90 seconds to 10 minutes after exposure. Subjects recorded pain on a 100-mm visual analog scale 60 seconds, 20 minutes, and 3 days after exposure. A 2-tailed paired t test was used to compare the difference in reduction of pain over time between the Mitigator-treated arms and the calamine-treated arms. RESULTS: At 60 seconds, the mean visual analog scale pain score was 23.9 mm for the Mitigator group and 24.5 mm for the calamine group. At 20 minutes, the mean score was 7.6 mm (delta = 16.3) for the Mitigator group and 12.7 mm (delta = 11.8) for the calamine group. At 3 days, the mean score was 2.4 mm (delta = 21.5) for the Mitigator group and 2.9 mm (delta = 21.6) for the calamine group. There was no significant difference between groups for change in visual analog scale pain score at 60 seconds, 20 minutes (P = .256), or 3 days (P = .64). CONCLUSIONS: There was no significant difference in pain relief between calamine and Mitigator for imported fire ant stings.
