investigAtion Evaluation of dental material series from patients with dental prostheses and suspicion of delayed hypersensitivity

Abstract: Background: Patients with oral sensitivity are common in our practice. Allergic contact dermatitis is one of the most frequent etiologies. oBJectIves: Evaluate oral contact dermatitis using the Brazilian standard series and complementary dental series in patients using dental prostheses, with or without oral complaints. Determine specific dental Brazilian series. Methods: Patients using dental prostheses with or without oral complaints realized patch tests. Brazilian standard series and complementary dental series were used according to ICDRG recommendations. The results were analysed according to age, sex, race, atopic conditions and symptoms associated. results: From 54 patients tested, 34 (63%) were positive at least to one substance. Nineteen had oral complaints, such as burning mouth, itch or oral erythema. There was no association between atopic condition and tests results. Without the oral series, just 23(42,6%) patients had a positive result. Using the Brazilian standard series with the complementary dental series we improved the positivity of the patch test to 47%. conclusIon: In patients using prostheses and with oral complaints, patch tests with Brazilian standard series with complementary dental series improve the tests positivity

Anaphylaxis triggered by prick test with latex extract: a case report

<div><p>ABSTRACT CONTEXT: Adverse reactions associated with prick tests are rare but may be present as serious systemic reactions. CASE REPORT: A 38-year-old female nursing technician complained of three episodes of anaphylaxis in one year, all in the workplace. To investigate latex allergy, the patient underwent the prick test with latex, and immediately developed a rash, itchy skin, hoarseness, dyspnea and dry cough. Her condition improved promptly after appropriate measures were established for controlling her anaphylaxis. CONCLUSION: The skin test must be performed under medical supervision, since complications that can lead to life-threatening reactions, if support measures are not readily implemented, have been attributed to this test.</p></div
