Antihistamines are widely used drugs. Hypersensitivity reactions with these drugs are rare and a challenge for the physician. We describe 5 outpatients who experienced urticaria after taking antihistamines. All 5 were treated at our outpatient clinic over a period of 15 years. The allergy workup included a clinical history, skin prick testing, patch testing with antihistamines, and single-blind...

We report the case of a 51-year-old woman who had an immediate skin reaction after subcutaneous administration of a local anesthetic (LA) composed of articaine and epinephrine before a dental procedure. The patient subsequently underwent further dental procedures without LA. Skin prick tests performed with commercial LAs (lidocaine, mepivacaine, bupivacaine and articaine) were negative with epi...

Background: The role of food allergy in atopic dermatitis (AD) is controversial. The aim of this study was to determine the frequency of food allergens in children with AD. Method: Fifty one atopic dermatitis children aged 6 months to 5 years entered our study. The severity of AD was determined by scoring index of AD (SCORAD). Skin prick test (SPT) was done using 15 allergens including the whit...

The increasing use of lupin in food processing poses a problem of potential (cross-)allergic reactions. To evaluate the prevalence of sensitization to lupin in comparison to that of other legumes skin prick tests were performed with lupin, pea, peanut, and soybean in atopic (n = 81) and non-atopic (n = 102) German adults. Of these 183 subjects, 20 subjects had to be excluded due to invalid skin...

BACKGROUND There are few references of allergic reaction to beans in childhood. We report the case of a seven years old boy who suffered from angioedema associated to inhalation of vapours from cooked white bean. METHODS skin prick tests (SPT) were performed by prick-by-prick with cooked white bean and legumes. It was also determined total IgE and specific IgE antibodies to bean and legumes w...
