1/31. adult onset grape hypersensitivity causing life threatening anaphylaxis.BACKGROUND: Adverse reactions to foods are encountered much less frequently in adults than in the children. adult onset hypersensitivity to grapes has not been previously reported. OBJECTIVE: Evaluation of a case of anaphylaxis that occurred as a result of the consumption of white grapes (Vitis vinifera). methods AND RESULTS: A 28-year-old woman experienced generalized urticaria, facial/oropharyngeal angioedema, and dizziness after eating a bunch of white grapes. She was treated in an emergency room for anaphylaxis. Previously, she had experienced two similar episodes after eating white grapes. The grape prick skin tests were strongly positive forming a pseudopod type reaction. The total serum IgE was 1918 ng/mL. The grape-specific serum IgE was weakly positive by the modified RAST and negative in the Pharmacia-Upjohn Cap System. CONCLUSION: hypersensitivity to a commonly consumed fruit such as grapes can develop late in life causing a near-fatal anaphylaxis.- - - - - - - - - - ranking = 1keywords = white (Clic here for more details about this article) |
2/31. Allergy to eggs from duck and goose without sensitization to hen egg proteins.BACKGROUND: eggs are among the foods most frequently causing allergy. Hen eggs are the most important. Those of other birds are of lesser significance. OBJECTIVE: We report an unusual case of food allergy after consumption of eggs from duck and goose in an adult patient without hen egg allergy. methods: Skin prick tests were performed with fresh white and yolk from eggs of duck and goose and egg white, egg yolk, ovalbumin, and ovomucoid from hen egg. Specific serum IgE was measured to hen egg proteins. SDS-PAGE and IgE immunoblotting were carried out with egg white extracts from hen, duck, and goose. RESULTS: skin tests were positive to egg whites from duck and goose. The skin tests and specific serum IgE were negative to hen egg proteins. immunoblotting demonstrated the presence of specific IgE to a proteic band of molecular weight around 45 kd. CONCLUSIONS: We report a patient with an IgE-mediated allergy to egg white from duck and goose without hen egg allergy. ovalbumin seems to be the responsible protein. The antigenic determinant of this protein seems to be specific of order Anseriforme and it is not present in the ovalbumin of order Galliforme.- - - - - - - - - - ranking = 1.6666666666667keywords = white (Clic here for more details about this article) |
3/31. Allergy to grape: a case report.We report a case of a 5-year-old child who suffered an oral allergy syndrome and lip angiedema after eating grapes. We obtained a positive prick test with commercial grape extract and a positive prick-by-prick test with pulp and peel of fresh white grape (Moscatel variety) and pulp and peel of blue grape. sodium dodecyl sulphate-polyacrylamide gel electrophoresis followed by immunoblotting revealed specific immunoglobulin e (IgE) antibodies in the patient's serum against a 94,000 molecular-weight antigenic band. lip open challenge was positive.- - - - - - - - - - ranking = 0.33333333333333keywords = white (Clic here for more details about this article) |
4/31. Allergy to cooked white potatoes in infants and young children: A cause of severe, chronic allergic disease.BACKGROUND: Cases of allergy to cooked potato in children have been reported, some with immediate and others with late reactions. The clinical effects of chronic allergic reactions to potato and the effectiveness of diet on such reactions have not been described previously. OBJECTIVE: We sought to evaluate the importance of cooked potato as an allergenic food in individual cases of atopy in children. methods: Eight atopic children were selected on the basis of suspicion of allergy to cooked potatoes: all had potato-specific IgE, 2 of 8 had experienced immediate allergic reactions, and 6 of 8 had eczema that improved with a potato-elimination diet (decrease in severity scoring of atopic dermatis [SCORAD] index of >50%). The patients were evaluated by using skin prick tests with homemade cooked and noncooked potato extracts and with a commercial extract and by using IgE immunoblots from SDS-PAGE patterns of potato extract. Seven patients were challenged with cooked potato. The control group consisted of 9 age-matched atopic children, 8 of them with eczema. RESULTS: The mean SCORAD index decreased from 43.3 before to 11.5 after elimination of potato from the diet. Potato CAP values ranged from 3.71 to greater than 100 kUa/L. Potato challenge results were positive in 7 of 7 patients. Skin prick test responses were positive for cooked potato extracts in 7 of 7 patients, for noncooked extracts in 7 of 7 patients, and for the commercial extract in 8 of 8 patients compared with in 0 of 9, 1 of 9, and 1 of 9 subjects in the control group, respectively. During immunoblotting, 8 of 8 patient sera recognized one or more protein bands compared with 0 of 9 control subject sera. CONCLUSION: Allergy to cooked potatoes is a cause of severe allergic disease, with immediate reactions and eczema in some atopic infants and young children.- - - - - - - - - - ranking = 1.3333333333333keywords = white (Clic here for more details about this article) |
5/31. White plaque of the lateral tongue.A healthy 48-year old white woman presented with a chief complaint of an 'irritated' sensation involving her tongue. The problem seemed to be limited to her left lateral tongue and had been noticed for at least six months by the patient. She also indicated the condition varied in severity.- - - - - - - - - - ranking = 0.33333333333333keywords = white (Clic here for more details about this article) |
6/31. Anaphylactic shock to oysters and white fish with generalized urticaria to prawns and white fish.Because seafood consumption is moderate-to-high in spain, allergic reactions to seafood such as fish, crustacea and mollusc are fairly frequent. The clinical features of these reactions depend on the implicated species and whether the reaction is provoked by ingestion, handling or vapor inhalation. Because different species have common antigenic structures, cross-sensitization is frequent, especially between crustaceans and molluscs. Contamination of fish by nematodes (anisakis) may produce severe reactions.We report the case of a female patient with no personal or family history of allergy who experienced two episodes of anaphylactic shock: the first occurred immediately after eating oysters and the second after ingestion of white fish. The patient also developed generalized urticaria provoked by crustacean (prawns) and white fish. The results of skin prick tests were negative for fish, shellfish, crustacean and oysters while in vitro tests were positive for oyster, prawns, anisakis, ascaris and echinococcus, although stool samples and gastric endoscopy were negative.- - - - - - - - - - ranking = 3.3333333333333keywords = white (Clic here for more details about this article) |
7/31. Buckwheat-induced anaphylaxis: a case report.Buckwheat (fagopyrum schulentum) is not taxonomically related to wheat and other cereal grains. Buckwheat flour is used as a wheat substitute in breads, biscuits, pancakes, and crepes. occupational exposure to buckwheat flour has been associated with rhinitis, conjunctivitis, contact urticaria, and occupational asthma. We present a patient who developed urticaria and hypotension after ingestion of buckwheat crepes. Skin testing by the prick technique revealed 3 positive reaction to buckwheat with negative reactions to other foods including wheat, egg white, and milk. RAST for anti-buckwheat IgE was strongly positive. Buckwheat ingestion is a potential cause of food-related anaphylaxis. There does not appear to be cross-reactivity between buckwheat and wheat allergy.- - - - - - - - - - ranking = 0.33333333333333keywords = white (Clic here for more details about this article) |
8/31. Grape anaphylaxis.Grape allergy is particularly rare in spite of the vast extension of Vitis vinifera cultivation on all continents. We report on the case of a 28-year-old woman who presented with allergic systemic reaction after eating white grapes (Vitis vinifera). She complained of two severe episodes of anaphylaxis after eating grapes, with generalized pruritus, acute generalized urticaria, facial swelling, lip and oropharingeal angioedema, and dysphagia. Both the episodes were treated at the Emergency Room level, with parenteral administration of corticosteroids and antihistamines. Skin prick tests with commercial extract of grapes provided a negative result, while prick by prick procedure performed with white grapes and white grape juice yielded a positive result. Grape-specific serum IgE were also detected. We conclude that in the diagnosis of grape allergy the currently available commercial extracts might not be completely reliable and the prick-by-prick procedure with fresh grapes should always be performed.- - - - - - - - - - ranking = 1keywords = white (Clic here for more details about this article) |
9/31. Hidden fish substance triggers allergy.Food allergy (hypersensitivity) is a form of adverse food reaction caused by an immunological response to a particular food. IgE-mediated food allergy is responsible for most immediate-type food-induced hypersensitivity reactions. The prevalence of food allergy in the general population, not including oral allergy syndrome, is about 1-2%. While adults might tend to be allergic to fish, crustaceans, peanuts, and tree nuts, children, on the other hand, tend to be allergic to cow's milk, egg white, wheat, and soy. Food is the most common eliciting factor of anaphylaxis (45%), followed by drugs (29%), and insect stings (21%). Our study describes a 3 1/2-year-old boy who is allergic to fish consumed via ingestion and inhalation. This case is a good example of how easily people with food allergies can unintentionally consume foods to which they allergic, and is a clear demonstration of the dangers of such effects.- - - - - - - - - - ranking = 0.33333333333333keywords = white (Clic here for more details about this article) |
10/31. Occupational asthma in the confectionary industry caused by sensitivity to egg.We report on a patient with asthma induced by occupational exposure to egg used to spray cakes before baking. A type I hypersensitivity to egg white was demonstrated by means of skin test, immunoassay for specific IgE, and immediate bronchial provocation test response to an egg white extract.- - - - - - - - - - ranking = 0.66666666666667keywords = white (Clic here for more details about this article) |
