Abstract
Food allergy (FA) is a serious health problem, and its incidence has been increasing especially in children. Wheat is one of the five most common foods that trigger allergic reactions in children. It is an increasingly recognised trigger for immune-mediated FAs, both Immunoglobulin E (IgE) and non-IgE mediated. We describe the case of a 4-year-old boy with a combination of symptoms due to IgE-mediated asthma worsened by IgE-non-dependent hypersensitivity to wheat demonstrated by a positive patch test. With the avoidance of wheat oral intake, we observed a progressive clinical improvement. To the best of our knowledge, this is the first report of a patient with IgE-non-dependent allergy to wheat presenting with chronic symptoms in one body system outside of the gastrointestinal tract and with negative skin prick test.

Abstract
Gluten related disorders (GRD) represent a wide spectrum of clinical manifestations that are triggered by the ingestion of gluten. Coeliac disease (CD) or gluten sensitive enteropathy is the most widely recognised, but extra-intestinal manifestations have also been increasingly identified and reported. Such manifestations may exist in the absence of enteropathy. Gluten sensitivity (GS) is another term that has been used to include all GRD, including those where there is serological positivity for GS related antibodies in the absence of an enteropathy. Gluten ataxia (GA) is the commonest extraintestinal neurological manifestation and it has been the subject of many publications. Other movement disorders (MDs) have also been reported in the context of GS. The aim of this review was to assess the current available medical literature concerning MDs and GS with and without enteropathy. A systematic search was performed while using PubMed database. A total of 48 articles met the inclusion criteria and were included in the present review. This review highlights that the phenomenology of gluten related MDs is broader than GA and demonstrates that gluten-free diet (GFD) is beneficial in a great percentage of such cases.

Abstract
Cinnamon rolls triggered anaphylactic reaction. The genesis could be wheat-dependent exercise-induced anaphylaxis Two case reports from our Department of Allergology illustrate the wheat-dependent exercise-induced anaphylaxis (WDEIA), which is a relatively rare, yet potentially fatal form of food allergy. Wheat (Triticum aestivum) is the most commonly grown crop world-wide, and some individuals cannot tolerate it due to wheat hypersensitivity. The most dangerous reaction is the anaphylaxis due to harmful immune responses to various parts of the wheat proteins. ω-5-gliadin is the major causative allergen in wheat hypersensitivity. WDEIA is a poorly recognized disorder. Therefore, any patient presenting anaphylactic reaction at the emergency department, typically after ingestion of wheat products followed by physical exercise within one to four hours, should be referred to an allergy clinic for the allergological evaluation. Further research should be carried out to better understand the mechanisms behind, and to increase the awareness on WDEIA.

Abstract
Background: Non-celiac wheat sensitivity (NCWS) is a new clinical entity in the world of gluten-related diseases. Nickel, the most frequent cause of contact allergy, can be found in wheat and results in systemic nickel allergy syndrome and mimics irritable bowel syndrome (IBS). Objective: To evaluate the frequency of contact dermatitis due to nickel allergy in NCWS patients diagnosed by a double-blind placebo-controlled (DBPC) challenge, and to identify the characteristics of NCWS patients with nickel allergy. Methods: We performed a prospective study of 60 patients (54 females, 6 males; mean age 34.1 ± 8.1 years) diagnosed with NCWS from December 2014 to November 2016; 80 age- and sex-matched subjects with functional gastrointestinal symptoms served as controls. Patients reporting contact dermatitis related to nickel-containing objects underwent nickel patch test (Clinicaltrials.gov registration number: NCT02750735). Results: Six out of sixty patients (10%) with NCWS suffered from contact dermatitis and nickel allergy and this frequency was statistically higher (p = 0.04) than observed in the control group (5%). The main clinical characteristic of NCWS patients with nickel allergy was a higher frequency of cutaneous symptoms after wheat ingestion compared to NCWS patients who did not suffer from nickel allergy (p < 0.0001). Conclusions: Contact dermatitis and nickel allergy are more frequent in NCWS patients than in subjects with functional gastrointestinal disorders; furthermore, these patients had a very high frequency of cutaneous manifestations after wheat ingestion. Nickel allergy should be evaluated in NCWS patients who have cutaneous manifestations after wheat ingestion.

Abstract
Celiac disease (CD) determines neurologic manifestations in 10% of all CD patients. We describe the most common clinical manifestations as cerebellar ataxia, gluten encephalopathy, multiple sclerosis, peripheral neuropathies, sensorineural hearing loss, epilepsy, headache, depression, cognitive deficiencies and other less described clinical conditions. Our aim is to perform, as more as possible, a review about the most recent update on the topics in international literature. It is important to consider clinical neurological manifestations in celiac patients and to research these conditions also in the follow-up because they may start also one year after the start of gluten free diet (GFD) as peripheral neuropathy. The association with autism is analysed and possible new association with non-celiac gluten sensitivity (NCGS) are considered.

Abstract
Irritable bowel syndrome (IBS) is one of the most common gastrointestinal disorders, having a prevalence of 12%-30% in the general population. Most patients with IBS attribute their symptoms to adverse food reactions. We review the role of diet in the pathogenesis of IBS and the importance of dietary factors in the management of these patients. The MEDLINE electronic database (1966 to Jan 2015) was searched using the following keywords: “food”, “diet”, “food allergy”, “food hypersensitivity”, “food intolerance”, “IBS”, “epidemiology”, “pathogenesis”, “pathophysiology”, “diagnosis”, “treatment”. We found 153 eligible papers; 80 were excluded because: not written in English, exclusive biochemical and experimental research, case reports, reviews, and research otherwise not relevant to our specific interest. We selected 73 papers: 43 original papers, 26 reviews and 4 letters to the editor. These papers focused on IBS pathogenesis, the association between IBS and atopy, and between IBS and food allergy, the relationship between IBS and non-celiac wheat sensitivity, the role of diet in IBS. Pending further scientific evidence, a cautious approach is advisable but the concept of food allergy should be included as a possible cause of IBS, and a dietary approach may have a place in the routine clinical management of IBS.

Abstract
Among grains and legumes, wheat and soybean are the most frequent and well-characterized allergenic foods. Wheat proteins are divided into water/salt-soluble and water/salt-insoluble (gluten) fractions. The most dominant allergen in the former is α-amylase/trypsin inhibitor, which acts as an inhaled allergen causing baker's asthma. Gluten allergens, including ω-5 gliadin and high- and low-molecular-weight glutenins, contribute to wheat-dependent exercise-induced anaphylaxis in adults and immediate-type wheat allergies, including anaphylaxis, in children. Recently, wheat allergies exclusively caused by hydrolyzed wheat proteins or deamidated glutens have been reported, and the presence of unique IgE-binding epitopes has been suggested. Soybean allergens contributing to immediate-type allergic reactions in children are present in seed storage proteins, namely Gly m 5, Gly m 6 and Gly m 8. However, pollen-related soybean allergy in adults is caused by the Bet v 1 homolog of soybeans, Gly m 4. Taken together, the varying clinical manifestations of wheat and soybean allergies are predominantly caused by their different allergen components.

Abstract
Celiac disease is an autoimmune systemic disease having among its clinical manifestations frequent symptoms common to rheumatologic diseases such as musculoskeletal pain, asthenia, and cognitive fatigue. It is associated with other autoimmune diseases like Sjögren disease. It is a well-characterized disease with specific diagnostic tests. Non-celiac gluten sensitivity is an emerging entity with symptoms similar to celiac disease, but without specific diagnostic tests. The concept of non-celiac gluten sensitivity and its diagnostic problems are reviewed, and the hypothesis of its association with fibromyalgia, spondyloarthritis, and autoimmune conditions is proposed. Clinical observations supporting the hypothesis are described, highlighting the benefit of treating non-celiac gluten sensitivity.

Abstract
BACKGROUND Food allergy to lupine has frequently been reported in patients allergic to peanut or soy, and cross-reactivity between these legumes is known. Moreover, respiratory allergy to lupine has been described after inhalation, mostly at workplaces. Our aim was to study the frequency of lupine sensitization in European bakers with suspected bakers' allergy. Furthermore, associations between sensitizations to lupine and other plant allergens were investigated. METHODS One hundred and sixteen bakers with work-related allergic symptoms but without known food allergies were examined. Specific IgE (sIgE) antibodies to wheat flour, rye flour, lupine, peanut, soy and the recombinant single birch protein rBet v 1 were quantified. Selected sera were tested for cross-reactivity using ImmunoCAP inhibition and ISAC microarrays. RESULTS Whereas 67% of bakers were sensitized to wheat and/or rye flour, 35% showed sIgE to peanut and 33% to lupine. All lupine-positive bakers also had sIgE to either wheat flour (89%) and/or peanut (92%), and lupine sIgE correlated significantly with sIgE to peanut, soy, wheat and rye flour. Used as an inhibitor, wheat flour inhibited IgE binding to lupine in 4 out of 8 sera, indicating cross-reactivity. In microarrays, these sera showed IgE binding to lipid transfer proteins, profilins and/or cross-reactive carbohydrate determinants. Further inhibition experiments suggest that these single allergens are involved in cross-reactivity. CONCLUSION One third of 116 symptomatic bakers showed sIgE to lupine. At least some of these sensitizations were based on cross-reactivity between lupine and wheat flour. However, the considerable sensitization rate could also be a sign that the use of lupine flour in bakeries may be of occupational relevance.

Abstract
We report the case of a 73 year old man on chronic aspirin therapy who went in anaphylactic shock during his daily farm chores following a meal rich in wheat products. The serum specific IgE assay (ImmunoCAP) showed strong positive specific IgE responses to ω-5 gliadin. A two-year period avoiding wheat meals 3 hours prior to exercise, resulted in a lack of further anaphylaxis; this results aided us in making the diagnosis.

Abstract
A 38-year-old woman was suffering from irregular headaches and sleepiness. She had used soap containing Glupearl 19S (hydrolyzed wheat proteins) every day for approximately one year and had experienced an episode of rash eruption on her face seven months ago. Wheat-specific IgE antibodies were detected in her serum. A Western blot analysis revealed a high titer of IgE antibodies against Glupearl 19S and wheat proteins. The patient was sensitive to these compounds in a skin prick test. After avoiding eating wheat, her headaches and sleepiness disappeared. A hidden food allergy is a possible cause of these symptoms.

Abstract
A case of rice allergy in a patient with bakers asthma is described. On ISAC 112 IgE reactivity to wheat alpha-amylase/trypsin inhibitor (nTri a aA_TI) and lipid tranfer protein (rTri a 14) was found. We hypothesize that the reaction by oral ingestion was elicited by homologous molecules in rice seeds.

Abstract
UNLABELLED Few studies concerning the importance of wheat allergy affecting the course ofatopic eczema in adolescents and adult patients exist. AIM The evaluation if wheat allergy can deteriorate the course of atopic eczema. Follow-up of patients with confirmed food allergy to wheat. METHOD Altogether 179 persons suffering from atopic eczema were included in the study: 51 men and 128 women entered the study with an average age of 26.2 (s.d. 9.5 years) Dermatological and allergological examinations were performed, including skin prick tests, atopy patch tests, and specific serum IgE for wheat, open exposure test and double-blind, placebo-controlled food challenge test with wheat flour. RESULTS Wheat allergy affecting the coures of atopic eczema was confirmed in eight patients (4.5%) out of 179 patients enrolled in this study by double-blind, placebo controlled food challenge test. The course of atopic eczema showed a positive trend in patients with confirmed food allergy at 3, 6, 9, 12 month follow-up (statistical evaluation with paired t-test) after the elimination of wheat flour. CONCLUSION Wheat allergy may play an important role in the worsening of atopic eczema (acting as a triggering exacerbating factor) only in a minority of adolescents and adult patients (4.5% in our study). The diagnostic methods (skin prick test, specific IgE, atopy patch test, history) cannot be used as separated tests for the determination of food allergy to wheat in patients with atopic eczema.Open exposure tests and double-blind, placebo-controlled food challenge should be used for the confirmation of wheat allergy affecting the course of atopic eczema.

Abstract
A 70-year-old man with a history of food-dependent exercise-induced anaphylaxis (FDEIA) since age 50 was admitted to the emergency department with chest pain and urticaria caused by FDEIA. Coronary angiography revealed total occlusion of the proximal left anterior descending coronary artery. After thrombus aspiration, a bare metal stent was placed into the culprit lesion, resulting in no residual stenosis. Urticaria disappeared on the second hospital day. This is the first reported case, to our knowledge, in which acute myocardial infarction followed FDEIA. Physicians should be aware of acute myocardial infarction as a rare but potential complication of FDEIA.

Abstract
BACKGROUND The National Institute for Occupational Safety and Health conducted a study to determine prevalences of sensitization to bakery-associated antigens (BAAs) and work-related respiratory symptoms at a large commercial bakery. METHODS The following measurements were carried out: personal breathing zone (PBZ) and general area (GA) monitoring for inhalable flour dust, α-amylase and wheat, a questionnaire, and blood tests for IgE specific to flour dust, wheat, α-amylase, and common aeroallergens. RESULTS Of 186 bakery employees present during our site visit, 161 completed the questionnaire and 96 allowed their blood to be drawn. The geometric mean PBZ and GA inhalable flour dust concentrations for the lower-exposure group was 0.235 mg/m(3), and for the higher-exposure group was 3.01 mg/m(3). Employees in the higher-exposure group had significantly higher prevalences of work-related wheezing, runny nose, stuffy nose, and frequent sneezing than the lower-exposure group. The prevalence of IgE specific to wheat was significantly higher among employees who ever had a job in the higher-exposure group or in production at another bakery at both the ≥ 0.10 kU/L and the ≥ 0.35 kU/L cutoffs, and to flour dust and α-amylase at the ≥ 0.10 kU/L cutoff, compared to the lower-exposure group. CONCLUSIONS Despite knowledge of the risks of exposure to flour being available for centuries, U.S. employees are still at risk of sensitization and respiratory symptoms from exposure to high levels of BAA.

Abstract
Food-dependent exercise-induced anaphylaxis (FDEIA) is a special form of food allergy where a food-intake alone does not induce any symptoms. However, allergic symptoms are elicited when triggering factors such as exercise or aspirin-intake are added after ingestion of the causative food. The most frequent causative foodstuff in Japan is wheat. The triggering factors, both exercise and aspirin-intake, facilitate allergen absorption from the gastrointestinal tract, resulting in allergic symptoms in the patients with wheat-dependent exercise-induced anaphylaxis (WDEIA). Analysis using purified wheat proteins revealed that approximately 80% of the patients with WDEIA have IgE reacting to omega-5 gliadin and the remaining of the patients to high molecular weight glutenin (HMW-glutenin). Simultaneous measurement of specific IgE to omega-5 gliadin and HMW-glutenin was found to be highly useful in diagnosing WDEIA compared with the routine diagnostic system for wheat.

Abstract
Food allergy may be clinically expressed by a variety of respiratory symptoms, which can be provoked either by IgE- or cellular mediated reactions. Among the diagnostic procedures, newly introduced atopy patch test seems to be important for diagnosis of cellular, delayed immune reactions. We studied the prevalence of positive atopy patch tests with food and inhalant allergens and the correlation between the positivity of atopy patch tests and questionnaire derived atopic and nonatopic espiratory symptoms and diseases in an unselected children population. We found a correlation between the positive patch test result with wheat and cough after physical effort, allergic rhino-conjunctivitis, and bronchitis recidivans. The subjects with positive skin reaction to egg suffered from allergic rhino-conjunctivitis and bronchial asthma. Food and inhalant allergens play an important role in the induction and exacerbation of some respiratory allergic diseases. The positive correlation of positive results of skin tests and history of some respiratory diseases and symptoms also on the population level confirm the importance of these tests in the diagnostic work-up of these allergic diseases.

Abstract
Food-dependent, exercise-induced anaphylaxis (FDEIA) is a clinically distinct form of anaphylaxis in which symptoms occur only when the patient exercises within a few hours of eating the food. Its precise mechanism remains unclear and has been reported to have a wide spectrum of presentations. The objective of this report is to show that the onset of FDEIA can be delayed for several hours and to emphasize the critical need for having self-injectable epinephrine available at all times. Our patient had several episodes of FDEIA to wheat shortly after exercise since the age of 11 years. At 16 years of age, 5 hours after exercise that followed eating a wheat-containing meal, the patient developed severe anaphylaxis with loss of consciousness. Skin-prick test was positive (4+) to wheat but negative to 41 other foods. Serum tryptase level 2 hours after onset of anaphylaxis was elevated. Other laboratory findings were within normal ranges. This case indicates that FDEIA can have a delayed onset for several hours. Because such delayed onset is unpredictable and can be life-threatening, it might be prudent for such patients to avoid the offending food totally or to avoid exercising for at least 6 hours after eating the food and to keep self-injectable epinephrine easily available at all times.

Abstract
Wheat omega-5 gliadin and a high m.w. glutenin subunit (HMW-glutenin) have been reported as major allergens in wheat-dependent exercise-induced anaphylaxis. A simultaneous detection of specific IgE to epitope sequences of both proteins is considered to be a reliable method for diagnosis of wheat-dependent exercise-induced anaphylaxis. However, the IgE-binding epitope of HMW-glutenin remains unknown. The aim of this study was to determine the IgE-binding epitopes of HMW-glutenin to establish a useful system of identifying patients with wheat-dependent exercise-induced anaphylaxis. For determination of IgE-binding epitopes of HMW-glutenin overlapping peptides were synthesized and reactivities of IgE Abs in the sera of patients to those peptides were analyzed. Three IgE-binding epitopes, QQPGQ, QQPGQGQQ, and QQSGQGQ, were identified within primary sequence of HMW-glutenin. Epitope peptides, which include IgE-binding sequences of omega-5 gliadin and a HMW-glutenin, were synthesized and peptide-specific IgE Abs were measured by CAP-System fluorescent enzyme immunoassay. Twenty-nine of 30 patients with wheat-dependent exercise-induced anaphylaxis had specific IgE Abs to these epitope peptides. None of the 25 sera from healthy subjects reacted to both epitope peptides. Twenty-five patients with atopic dermatitis who had specific IgE to wheat and/or gluten had very low or nonexistent levels of epitope peptide-specific IgE Abs. These results indicated that measurement of IgE levels specific to epitope peptides of omega-5 gliadin and HMW-glutenin is useful as an in vitro diagnostic method for the assessment of patients with wheat-dependent exercise-induced anaphylaxis.

Abstract
Exercise-induced anaphylaxis (EIA) is defined as the onset of allergic symptoms during, or immediately after, exercise, the clinical signs being various degrees of urticaria, angioedema, respiratory and gastrointestinal signs and even anaphylactic shock. Food-dependent exercise-induced anaphylaxis (FDEIA) introduces food in the syndrome and is revealed by a chronological sequence in which food intake, followed by exercise, induces symptoms after a varying period. When the food intake and the exercise are independent of each other, there are no symptoms. FDEIA is not very frequent. Identifying the culprit food allergen depends on the patient's eating habits. Crustaceans and wheat flour are the two commonest but others foods can be implicated. The patho-physiology of FDEIA has not been clearly established but it appears to result from degranulation of mast cells. As with food allergy, FDEIA diagnosis is based on interview, skin and biological tests and challenge. For the clinical signs of allergy, antihistamines, corticosteroids and epinephrine may be administered. Prophylaxis aims to prevent a recurrence; the patient should be given an emergency kit to deal with any recurrent episode. After the food allergen has been identified, it should be avoided for at least 4 to 5 hours before any exercise.

Abstract
Wheat omega-5 gliadin has been identified as a major allergen in wheat-dependent exercise-induced anaphylaxis. We have detected seven IgE-binding epitopes in primary sequence of the protein. We newly identified four additional IgE-binding epitope sequences, QQFHQQQ, QSPEQQQ, YQQYPQQ and QQPPQQ, in three patients with wheat-dependent exercise-induced anaphylaxis in this study. Diagnosis and therapy of food allergy would benefit from the availability of defined recombinant allergens. However, because omega-5 gliadin gene has not been cloned, recombinant protein is currently unavailable. We sought to clone the omega-5 gliadin gene and produce the homogeneous recombinant protein for use in an in vitro diagnostic tool. Using a PCR-based strategy we isolated two full-length omega-5 gliadin genes, designated omega-5 and omega-5b, from wheat genomic DNA and determined the nucleotide sequences. The protein encoded by omega-5a was predicted to be 439 amino acids long with a calculated mass of 53 kDa; the omega-5b gene would encode a 393 amino acid, but it contains two stop codons indicating that omega-5b is pseudogene. The C-terminal half (178 amino acids) of the omega-5a gliadin protein, including all 11 IgE-binding epitope sequences, was expressed in Escherichia coli by means of the pET system and purified using RP-HPLC. Western blot analysis and dot blot inhibition assay of recombinant and native omega-5 gliadin purified from wheat flour demonstrated that recombinant protein had IgE-binding ability. Our results suggest that the recombinant protein can be a useful tool for identifying patients with wheat-dependent exercise-induced anaphylaxis in vitro.

Abstract
Headache, and migraine in particular, is the main neurological reason for consultation. We present the case of a 48–year–old woman who experienced a transformation of her episodic migraine attacks into daily headache episodes due to the ingestion of biscuits containing wheat as their main ingredient. This experience emphasises that a good clinical interview remains the most important point in the diagnosis and management of headache.

Abstract
BACKGROUND Wheat can cause severe immunoglobulin E (IgE)-mediated systemic reactions including anaphylaxis but knowledge on relevant wheat allergens at the molecular level is scanty. METHODS Seven children (aged from 6 months to 13 years) experiencing from 2 to 10 anaphylactic reactions in a year after eating food-containing wheat were examined. Purified omega-5 gliadin was used as an allergen in IgE enzyme-linked immunosorbent assay (ELISA) and in skin prick testing (SPT). Wheat CAP radioallergosorbent test (RAST) and SPT were also examined. RESULTS All seven anaphylactic children, but none of 15 control subjects had IgE antibodies to omega-5 gliadin in ELISA. Five of the six tested anaphylactic children showed positive SPT to omega-5 and crude gliadin, and all seven had positive wheat CAP RAST and SPT. One child was challenged with wheat, which caused anaphylaxis. After adherence to a wheat-free diet four children remained symptomless and three experienced one to two anaphylactic reactions. CONCLUSION The present results show that wheat omega-5 gliadin is a major sensitizing allergen in children with wheat-induced anaphylaxis. They also suggest that omega-5 gliadin IgE ELISA could be used as a diagnostic test for this severe allergy.

Abstract
BACKGROUND Wheat is a food allergen that occasionally causes a systemic allergic reaction; however, little is known about the quantities of wheat allergen required to evoke allergic symptoms. OBJECTIVE To report the case of a wheat allergic boy who experienced systemic urticaria and angioedema within 40 minutes after the ingestion of 9 g of packed rice crackers. METHODS A skin prick test and IgE immunoblotting with wheat proteins were performed. Contamination of wheat protein in the offending rice cracker and other processed rice crackers from local food retail outlets, with labels that did not mention wheat, was examined with enzyme-linked immunosorbent assaying. RESULTS A skin reaction to wheat was positive. IgE-bound bands were observed with water- and salt-soluble wheat protein and ethanol-soluble wheat gliadin in immunoblotting. A trace quantity of wheat protein, 1.50 microg/g, was determined in the offending rice cracker. In addition, 3 of 8 other kinds of processed rice crackers were contaminated by wheat protein, with levels ranging from 0.26 to 1.13 microg/g. CONCLUSIONS Approximately 13.5 microg of wheat protein can elicit a systemic adverse reaction in highly sensitive, wheat allergic individuals. The present study confirms the need for control of contamination of food by nondeclared proteins.

Abstract
BACKGROUND Despite its worldwide and abundant consumption, beer has rarely been found to cause anaphylaxis. Barley malt contained in lager beers seems to be an important elicitor. OBJECTIVE To report the unusual case of severe anaphylaxis following the ingestion of wheat beer. METHODS A 59-year-old man experienced angioedema, generalized urticaria, and unconsciousness after ingestion of wheat beer. He tolerated lager beer well. For diagnostic evaluation, skin prick tests, oral challenge tests, and identification of specific IgE antibodies were performed. RESULTS Skin prick test results with standard series of common aeroallergens and food allergens were negative with the exception of a 1 + reaction to wheat flour. The results of skin prick tests with native materials were positive for 2 brands of wheat beer and wheat malt shred but negative for baker's yeast, hops, and a brand of lager beer. Oral challenges with wheat beer or wheat flour elicited urticaria. By CAP-FEIA, specific IgE antibodies to wheat and barley flour but not to hops or baker's yeast were found in serum. Immunoblot analysis revealed that patient's IgE was bound to a protein of approximately 35 kDa in wheat extract. CONCLUSIONS This is the first report, to our knowledge, on anaphylaxis to beer attributable to wheat allergy.

Abstract
Asthma is one of the most prominent respiratory diseases worldwide. It is defined by airflow limitation and/or airway hyperresponsiveness and can be exacerbated by a number of environmental allergens. When allergic asthma exacerbations are attributed to stimuli in a particular work environment, then occupational asthma must be considered. Incidence estimates vary, but in 1999 the Surveillance of Work-Related and Occupational Respiratory Disease in the United Kingdom estimated 4293 incident cases of occupational respiratory disease, an increase of 1427 cases over the previous year. Occupational asthma represented 26% of these cases. Baker's asthma is one of the most frequently reported types of occupational asthma in several countries. Diagniostic steps include thorough history, careful exam, and demonstration of functional reversible airflow obstruction. Treatment modalities used for occupational asthma are similar to those used in the management of other forms of asthma, with particular attention to reducing the level of exposure to the inciting allergen.

Abstract
Allergy is a very uncommon cause of diarrhoea. Other mechanisms, medical diseases and infections, psychological and pseudoallergic reactions, intolerance reactions, and enzyme defects/deficiency, and many other conditions are much more common. If food allergy is strongly suspected diagnosis may be difficult, even for allergologists, as it requires a mosaic of history, skin and in vitro tests, diagnostic diet, and even provocation tests. It is important to recognise diarrhoea "accompanying" allergic urticaria and anaphylactic reactions as part of the symptomatology of the primary dermatological or allergic disease and to refer the patient to the appropriate specialist.

Abstract
BACKGROUND There is increasing consensus about the significance of food allergens in the pathogenesis of atopic dermatitis (AD) in infancy and childhood, with cow's milk and egg accounting for most of the reactions. Previous studies have indicated that multiple food sensitization, such as cereals, is very common in patients with cow's milk allergy (CMA). Evidence is lacking, however, as to its clinical relevance. OBJECTIVE The purpose of this study was to determine the concurrent occurrence of cereal allergy among children with challenge-proven CMA who have residual symptoms, such as AD and/or gastrointestinal symptoms, during cow's milk elimination diet. Further, we sought to evaluate the utility of patch testing in prescreening foods other than cow's milk behind allergic symptoms in children. METHODS The study population comprised 90 children, aged from 2.5 to 36 months (mean 1.1 years), with challenge-proven CMA. As a result of residual symptoms during meticulous cow's milk elimination diet (AD: n=80, and gastrointestinal: n=10), the children were put on a cereal elimination diet (oats, wheat, rye, and barley) and skin prick tests (SPT) and patch testing with cereals were performed. Open cereal challenge was performed to confirm cereal allergy. RESULTS Cereal challenge was positive in 66 (73%) of the children with CMA. Of them, 17% reacted with immediate reactions and delayed-onset reactions were seen in 83% of the children. SPT was positive in 23%, patch test in 67%, and either SPT or patch test was positive in 73% of the children with cereal allergy. SPT gave the best positive predictive value, whereas SPT together with patch test gave the best negative predictive value. CONCLUSIONS Residual symptoms, such as eczema or gastrointestinal symptoms in CMA children may be a sign of undetected allergy to other food antigens. SPT with cereals aids in diagnosing cereal allergy in small children, especially when used together with patch testing.

Abstract
A forty-year-old military personnel presented with generalized urticaria, syncope, shortness of breath and headache associated with jogging after ingestion of a taro-filled bun and a red bean-filled bun. Skin prick test was positive for bread, taro and wheat but negative for red bean and preservative. Exercise challenge tests were performed. Exercise alone failed to induce any allergic reaction but exercise following ingestion of a taro-filled bun and a red bean-filled bun induced generalized urticaria. Since the patients stopped taking these types of food, the urticaria has not returned. This is the first case report of food-dependent, exercise-induced anaphylaxis in Thailand.

Abstract
BACKGROUND The involvement of IgE-mediated hypersensitivity reactions in the genesis of gastrointestinal symptoms after ingestion of foods containing wheat has been rarely reported. OBJECTIVE To detect IgE specifically binding to wheat proteins in the sera of atopic and non-atopic patients suffering from gastrointestinal symptoms after ingestion of wheat and to evaluate the reliability of skin prick test and CAP in the diagnosis of food allergy to wheat. METHODS The sera of patients (10 atopic and 10 non-atopic) previously diagnosed as suffering from irritable bowel syndrome and complaining of symptoms after wheat ingestion were analysed by immunoblotting for IgE binding to water/salt-soluble and insoluble wheat flour proteins. RESULTS All the atopic patients and only one of the non-atopic patients were positive to wheat CAP. For the patients tested, skin prick test was positive for all the atopic patients and for only one of the non-atopic patients. However, immunoblotting experiments showed the presence of specific IgE to wheat proteins in all the patients. Ten out of 11 of the wheat CAP-positive patients had IgE binding to a soluble 16-kDa band, but the same band was recognized, in a slighter way, by only two out of nine of the wheat CAP-negative patients. Moreover, although almost all of the patients were negative in CAP testing with gluten, 19 out of 20 recognized protein bands belonging to the prolamin fraction. CONCLUSIONS For the atopic patients the positivity to skin prick test and CAP to wheat was in accordance with the immunoblotting results and a food allergy to wheat could be diagnosed. In these patients a major allergen was a 16-kDa band corresponding to members of the cereal alpha-amylase/trypsin inhibitors protein family, the major allergens involved in baker's asthma. In the non-atopic patients the positive immunoblotting results contrasted with the responses of the allergologic tests, indicating that the allergenic wheat protein preparations currently used are of limited value in detecting specific IgE to wheat and that the fraction of irritable bowel syndrome (IBS) patients with food allergy may be larger than believed.
