OBJECTIVES: To review oral allergy syndrome (OAS). METHODS: We searched several medical literature data bases with the following key words: "oral allergy syndrome," "OAS," "pollen-food allergy syndrome," "PFAS," "allergy," "diagnosis," "treatment." RESULTS: Oral allergy syndrome (OAS), also called "pollen-food allergy syndrome," is a type of food allergy brought about by flavors, nuts, raw fruit, and vegetables. The most well-known symptoms are mouth and throat itching, which starts rapidly after a food is placed in the mouth, and that, as a rule, continues for just a couple of minutes after the food has been swallowed...

Tree nut allergy affects approximately 1.4-2.3%, depending on the study methodology, patient age, and region in which the study was conducted.1,2 Tree nut allergy can be severe, and tends to persist throughout life.1,3 Tree nut is not a singular allergen like the other allergens-we use the term "tree nut" to refer to these items, but in essence it can refer to one nut, eight nuts, or per the US Food and Drug Agency classification, on the order of 19 items.1,4 Older, more conservative practice is to treat one nut as "all nuts", and instruct avoidance of all tree nuts where there is a clinical allergy proven to just one...

A 51-year-old woman with a history of asthma and Hashimoto's thyroiditis presented to the dermatology service with a chief complaint of "itchy bumpy rashes" that persisted beyond 24 hours. She noted that, 3 days prior to the onset of urticaria, a pyrroloquinoline quinone supplement had been started. The urticaria was accompanied by variable episodes of transient facial swelling and difficulty breathing. The patient noted that exposure to fish, nuts, and nonsteroidal anti-inflammatory drugs triggered facial swelling...

BACKGROUND: Food allergy health-related quality of life has been defined, but self-efficacy is poorly described. OBJECTIVE: To examine the preliminary reliability, validity, and clinical performance of a novel food allergy self-efficacy index. METHODS: An 8-item Food Allergy Self-Efficacy Questionnaire (FASEQ) was adapted for food allergy-related themes and coadministered with the Food Allergy Quality of Life Parental Burden (FAQL-PB) index to caregivers self-reporting a food allergic child (group A) and those with children followed up at a food allergy referral center clinic (group B)...

Pectin is used in several foods as an additive and a thickner. But some cases of anaphylaxis have been reported. Most of these are induced by occasional exposures; however, no cases of anaphylaxis after eating a Citrus unshiu, the albedo of which is rich in pectin, have been reported.A 7-year-old girl developed barking cough and pruritus approximately two hours after eating a frozen Citrus unshiu. She had a history of anaphylaxis induced by consuming cashew nuts. Skin testing and basophil activation tests were performed using a commercially available pectin product...

Food allergy to pumpkin seed is considered very rare, and only some isolated case reports have so far been published. We report here a case of food anaphylaxis to pumpkin seed in an eight-year-old boy, who tolerated all other edible seeds, peanut and tree nuts, as well as pulp of different kinds of pumpkins and other fruits of the Cucurbitaceae family. From this observation, a review of the botanical, historical, medicinal and allergenic aspects of pumpkin and its seeds is proposed. With the advent of diets rich in omega-3 and omega-6 polyunsaturated fatty acids, edible seeds like pumpkin seed have been incorporated in the modern diet...

REVIEW
Philippe A Eigenmann
Food challenges are standard in the diagnosis in patients suspected of being allergic to food. However, their role is regularly questioned due to the time required to perform them, and to their cost and the inherent risk of severe reactions. Food challenges have been challenged by recent advances defining threshold values for food-specific IgE helping to predict the probability of having symptoms to the suspected food. Also, identification of major allergens to various highly allergenic foods such as peanuts or tree nuts have contributed to an increased accuracy of IgE testing...

REVIEW
Kara L Kliewer, Alison M Cassin, Carina Venter
Eosinophilic esophagitis (EoE) is a food antigen-mediated disorder of the esophagus characterized by eosinophil predominant inflammation and symptoms of esophageal dysfunction. Dietary antigen elimination induces clinical and histological remission in patients with EoE. The most restrictive of elimination diets (the elemental diet) removes all possible food antigens while empiric elimination diets remove all (or a subset) of food antigens most commonly reported to cause esophageal eosinophilia and food allergies (milk, egg, wheat, soy, peanuts, tree nuts, fish, or legumes)...

There is currently no cure for food allergies, and sufferers can only rely on the correct labeling of foods toavoid allergens. Hence, it is important that analytical methods are sensitive and accurate enough to screen for the presence of multiple allergens in food products. In this study, we developed an LC-tandem MS method that is able to simultaneously screen or quantify the signature tryptic peptides of multiple allergen commodities. This method is capable of screening and identifying egg white, skim milk, peanut, soy, and tree nuts (almond, Brazil nut, cashew, hazelnut, pecan, pine nut, pistachio, and walnut) at a detection limit of 10 ppm in incurred bread and cookies...

BACKGROUND: Adolescents are at the highest risk of death from anaphylaxis, yet few population-based studies have described the frequencies and risk factors for allergic reactions caused by accidental allergen ingestion in this group. METHODS: We describe the prevalence, frequency, and associated risk factors for recent adverse food reactions in 10- to 14-year-olds in Melbourne, Australia, recruited from a stratified, random, population-based sample of schools (SchoolNuts, n = 9663; 48% response rate)...

The prevalence of allergy is markedly low in children growing up on farms. An increasing number of studies indicate that the timing of food introduction may affect allergy development. We aimed to investigate if protection against allergy in farm environments may be mediated through differences in food-introduction practices between farm and non-farm families, using an explorative approach. Twenty-eight farm and 37 non-farm children were included in the FARMFLORA birth cohort. Practices of breastfeeding and introduction of formulas and complementary foods were collected by questionnaires at 6, 12, and 18 months of age...

Dana Shaker
In a world where food allergy is still an incurable disease, law and regulation stand as necessary mechanisms to provide food-allergic consumers with the information they need to protect their health. The Food Allergen Labeling and Consumer Protection Act of 2004 provided specific labeling requirements for the “Top Eight” allergens in the U.S.: milk, soy, gluten, egg, tree nut, peanut, fish, and Crustacean shellfish. Since then, sesame has become more prevalent as an allergen and remains just as dangerous, inducing anaphylactic shock in some sesame-allergic individuals...

BACKGROUND: Ambiguities exist regarding the diagnosis of tree-nut allergy, necessitating either elimination or performance of oral food challenges (OFC). OBJECTIVE: To examine the co-incidences of allergies among tree-nuts and improve diagnostic testing to minimize the need for OFC. METHODS: Eighty three patients prospectively evaluated for walnut, pecan, cashew, pistachio, hazelnut and almond allergy. A history of previous reactions was obtained and standardized skin prick tests (SPT) using finely ground tree-nut solution and basophil activation tests (BAT) were performed...

Background: IgE sensitization to storage proteins from nuts and seed is often related to severe allergic symptoms. There is a risk of immunological IgE cross-reactivity between storage proteins from different species. The potential clinical implication of such cross-reactivity is that allergens other than the known sensitizer can cause allergic symptoms. Previous studies have suggested that kiwi seed storage proteins may constitute hidden food allergens causing cross-reactive IgE-binding with peanut and other tree nut homologs, thereby mediating a potential risk of causing allergy symptoms among peanut ant tree nut allergic individuals...

BACKGROUND: Early introduction of dietary peanut in high-risk infants with severe eczema and/or egg allergy prevented peanut allergy at 5 years of age in the LEAP Study; the protective effect persisted after 12 months of avoiding peanuts in the LEAP-On Study. It is unclear whether this benefit is allergen and allergic-disease specific. OBJECTIVE: To assess the impact of early introduction of peanut on the development of allergic disease, food sensitization and aeroallergen sensitization...
