Peanut and soybean are members of the Leguminosae family. They are two of the eight foods that account for the most significant food allergies in the US and Europe. Allergic reactions to other legume species can be of importance in other regions of the world. The major allergens from peanut and soybean have been extensively analyzed and members of new protein families identified as potential marker allergens for symptom severity. Important recent advances concerning their molecular properties or clinical relevance have been made...

Pistachio nut (Pistacia vera) is highly appreciated for its organoleptic characteristics and potential health benefits. However, this tree nut is also responsible for triggering moderate to severe IgE-mediated reactions in allergic individuals. Currently, pistachio nut allergy has gained some special attention, mainly due to its intrinsic relation with cashew nut allergy. Like for other nuts, the prevalence of pistachio nut allergy seems to be increasing at a global scale. Until now, there are five allergenic proteins officially listed for pistachio nut (Pis v 1, Pis v 2, Pis v 3, Pis v 4 and Pis v 5)...

Food allergies are recognised as a global health concern. In order to protect allergic consumers from severe symptoms, allergenic risk assessment for well known foods and foods containing genetically modified ingredients was installed. However, population is steadily growing and there is a rising need to provide adequate protein-based foods, including novel sources, not yet used for human consumption. In this context safety issues such as a potential increased allergenic risk need to be assessed before marketing novel food sources...

Contact stomatitis occurs in up to 10% of the population. Mechanical or chemical irritation, ill-fitting dentures, and dental fillings can induce irritant contact stomatitis. Type I hypersensitivity and type IV hypersensitivity to dental products and foods are frequently responsible for the allergic types of contact stomatitis. We review the causal agents of contact stomatitis, the differential diagnoses, diagnostic testing, and potential treatment.

Food protein-induced enterocolitis syndrome (FPIES) is a non-IgE mediated gastrointestinal food hypersensitivity, characterized by profuse vomiting, frequently associated to pallor or/and lethargy that appears within 1 to 3 hours after ingestion of the offending food. There is a less frequent chronic form of FPIES, presenting with protracted vomiting, diarrhea or both, accompanied by poor growth. Although FPIES is considered a rare allergic disorder, in the last few years there have been an increasing number of reports about it indicating if not a real increase in incidence, at least an increased awareness of this condition by pediatricians...

Food allergies affect up to 8% of children in the United States and may occasionally lead to severe life-threatening reactions. Because there is currently no cure for food allergies, strict avoidance of the allergen-containing foods is the only means of preventing an allergic reaction. Consumers rely on food manufacturers to reliably track and declare the presence of food allergens in products. Over the past 10 to 20 years, the food industry has increasingly adopted allergen control approaches in its processing facilities...

BACKGROUND: Neuroendocrine tumors (NETs) are heterogeneous neoplasms that originate from cells with a secretory function. Small bowel NETs (SB-NETs) are related to serotonin hypersecretion which causes: flushing, diarrhea, abdominal pain, bronchoconstriction and heart involvement, also known as carcinoid syndrome (CS). CS can be confused with an allergic reaction and thus should be considered as a differential diagnosis in the allergy consult. We present the case of a pediatric patient initially referred under the suspicion of food allergies...
