Histamine is the main mediator of urticaria and H1-receptor antagonists represent the treatment of choice in all patients with chronic urticaria. Leukotriene receptor antagonists as montelukast have also been used in patients with chronic urticaria unresponsive to H1-antihistamines alone.We report a patient with chronic urticaria whose disease was paradoxically exacerbated by H1-antihistamines and montelukast, and […]

In literature it has been described a high risk of systemic reaction after blood-sucking Dyptera bites, like mosquitoes and horsefly, in people sensitive to hymenoptera. A 51 year old man, allergic to hymenoptera venom and with a history of IV reaction after Mueller , who has been treated with Vespula sp. ITS for the last […]
We report a case of a two-year-old boy with atopic dermatitis treated with antibiotics for pharyngitis and acute otitis media and subsequently developed targetoid and ulcerated blister mucocutaneous lesions. Diagnostic workup revealed eczema herpeticum and HSV viremia. To our knowledge, this is the first reported case of a patient with atopic dermatitis presenting with erythema […]
In this report we describe un unusual case of exclusive allergic sensitization to furry animals, as a possible study model to speculate about different modalities of sensitization to allergens of common and less common mammalian species. A 27-year-old woman referred in our Allergological Centre for the occurrence of conjunctival and severe respiratory symptoms after contact […]
An unusual case of both banana and tomato allergy is reported. In vitro tests showed that both co-sensitization to and co-recognition of allergen in the two fruits were present. Interestingly, the patients showed IgE reactivity to hitherto not described, high molecular weight allergens.
The authors describe the case of a 28-year-old woman, with a history of recurrent bacterial infections since childhood and multiple hospitalizations for pneumonia, with important pulmonary sequelae, including bronchiectasis which warranted the need to perform a left lobectomy and lingulectomia at age 13. After diagnostic work up, the diagnosis of hypogammaglobulinemia with hyper-IgM was established, […]
Insulin allergy was not uncommon in the past, but has lowered with the introduction of human recombinant insulin. Human recombinant insulin allergy is a rare condition, now reported in less than 1% of treated patients. However, it is a serious condition that requires an immediate allergological work-up. In this study, we describe 4 cases of […]
We describe an isolated eosinophilic pyloric stenosis in a young female. She was referred for abdominal pain, fever, weight loss and eosinophilia. A sonographic examination revealed a concentric pyloric stenosis, with antral palsy and ascites. The endoscopy confirmed the diagnosis of eosinophilic infiltration of the pylorum. After a short course of systemic steroids, the patient […]
Food protein induced enterocolitis syndrome (FPIES) is a food-related non-IgE-mediated gastrointestinal hypersensitivity disorder. Atypical FPIES is characterized by the presence of specific IgE for the causative food. The guidelines suggested for diagnostic Oral Food Challenge in pediatric patients affected by suspected FPIES are different from the ones for children with IgE-mediated food allergy. We describe […]
We report the case of a 62-year old man who presented a wheat-dependent, exerciseinduced anaphylaxis(WDEIA).The case illustrates the usefulness of skin prick test not only with wheat extract, but also with native gliadin extract. Moreover we confirm the value of recombinant IgE dosage with rTri a 19 omega-5 gliadin in the diagnostic pathway of this […]
