1/139. latex allergy in atopic children.The incidence of positive circulating specific immunoglobulin e (IgE) antibodies to latex and evidence of clinical latex sensitivity appears to be increasing since its first description in 1979. Although heightened medical awareness may be a factor, exposure to latex products, particularly rubber gloves, has increased since the discovery of the human immunodeficiency virus (hiv). Atopic individuals are at greater risk of developing latex sensitivity. We identified seven children with atopic eczema who were known to have clinically significant latex allergy and examined the relationship of prior exposure to latex gloves. All children had significant serum levels of specific IgE to latex. Before developing clinical symptoms of latex allergy, all had been exposed to latex in the form of gloves during either inpatient or outpatient treatments of their skin. Exposure of atopic individuals to latex gloves could be a major risk factor for sensitization and could increase the incidence of serious reactions.- - - - - - - - - - ranking = 1keywords = sensitivity (Clic here for more details about this article) |
2/139. 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 = 3keywords = sensitivity (Clic here for more details about this article) |
3/139. Lupine-induced anaphylaxis.BACKGROUND: Legumes are one of the most common foods causing allergic reactions in children and adults. Cross-reacting antibodies are frequently demonstrated in this family but the real clinical cross-reactivity is uncommon. OBJECTIVE: To report a case of lupine-induced anaphylaxis and to elucidate in vivo and in vitro cross-reactivity with some legumes. methods: skin prick test (SPT) with some legumes were performed. Cap-IgE, ELISA-IgE, and immunoblotting were carried out. Open oral challenges with some legumes were performed. Cross-reactivity was studied by ELISA and immunoblotting inhibition. RESULTS: The results demonstrated type-I hypersensitivity reactions with lupine and some other legumes. Cap-IgE with peanut was positive but the SPT and ELISA-IgE were negative and the patient tolerated a peanut challenge. ELISA inhibition revealed a partial inhibition (62%) using lupine as the solid phase. Partial inhibition was demonstrated by immunoblotting inhibition. Open oral challenge with peanut and green bean were negative but positive with pea. CONCLUSION: We present a lupine sensitized patient with positive SPT and in vitro cross-reactivity with other legumes. Clinical cross-reactivity progressively developed over a 5-year period. Discrepancies were found between the clinical aspect and in vitro study of peanut allergy. Factors determining the wide variability in cross-reactivity among individuals are still obscure.- - - - - - - - - - ranking = 0.5keywords = sensitivity (Clic here for more details about this article) |
4/139. Food protein-induced enterocolitis syndrome: clinical perspectives.Food Protein-Induced enterocolitis syndrome (FPIES) is a symptom complex of severe vomiting and diarrhea caused by non-IgE-mediated allergy to cow's milk and/or soy in infants. Symptoms typically begin in the first month of life in association with failure to thrive and may progress to acidemia and methemoglobinemia. Symptoms resolve after the causal protein (usually sensitivity to both cow's milk and soy) is removed from the diet. Symptoms recur approximately 2 hours after reintroduction of the protein along with a coincident elevation of the peripheral blood polymorphonuclear leukocyte count. The sensitivity is usually outgrown by 3 years of age. The purpose of this review is to delineate the characteristic clinical features, diagnosis and management of FPIES. Furthermore, infantile FPIES will be discussed in relation to clinical syndromes that share features with it ("atypical FPIES") and other food-allergic disorders affecting the gastrointestinal tract.- - - - - - - - - - ranking = 1keywords = sensitivity (Clic here for more details about this article) |
5/139. Radiographic features of eosinophilic gastroenteritis (allergic gastroenteropathy) of childhood.The child with eosinophilic gastroenteritis has failure to thrive, a history of allergy or asthma, iron deficiency anemia, and peripheral eosinophilia. This type of eosinophilic gastroenteritis has earned the designation "allergic gastroenteropathy." Pathologic change in the gastric antrum of six children with this disease correlated with an abnormal air-contrast examination of the antrum. The affected children had an irregular, lacy, antral surface rather than the smooth, bald surface seen in normal children. The small bowel in allergic gastroenteropathy is usually abnormal but nonspecific as to etiology. Much more specific is the combination of small bowel and gastric antral abnormalities. Findings encourage air-contrast radiography of the antrum in children with suspected allergic gastroenteropathy.- - - - - - - - - - ranking = 0.00061715078430157keywords = contrast (Clic here for more details about this article) |
6/139. Eosinophilic gastritis due to anisakis: a case report.BACKGROUND: the parasite anisakis simplex is a helminth included in the nematode class. When man eats raw or rare fish and cephalopods infested by anisakis larvae, he can acquire the parasitic disease (anisakidosis). The parasite can also originate manifestations of immediate IgE mediated hypersensitivity in patients with sensitisation to it. methods AND RESULTS: we present the case of a 14 year old boy diagnosed of eosinophilic gastritis after endoscopic examination and biopsy associated to recurrent abdominal pain. After allergologic study, a type I hypersensitivity mechanism against anisakis simplex is confirmed by means of prick test, antigen specific IgE determination and antigen specific histamine release test. Sensitisation against fish proteins is ruled out as well as parasitic infestation. CONCLUSIONS: in this case report we demonstrate a type I hypersensitivity mechanism against anisakis simplex in a patient diagnosed of eosinophilic gastritis. This can be suspected in cases of gastritis or non filiated enteritis with a torpid evolution following the conventional treatment and especially if the onset of the symptoms is related with the intake of fish. The therapeutic success was reached when fish and shellfish were taken out of the diet. After two years without seafood ingestion our patient is asymptomatic and the allergologic study has been normalised.- - - - - - - - - - ranking = 1.5keywords = sensitivity (Clic here for more details about this article) |
7/139. Pistachio nut hypersensitivity: identification of pistachio nut allergens.Type I hypersensitivity to pistachio nut antigens was demonstrated in three patients by means of immediate skin-test reactivity, specific IgE determination by a fluoroimmunoassay (CAP), CAP-inhibition and leucocyte histamine release. Sensitization to other dried fruits and pollens was observed in the patients. The CAP-inhibition studies revealed significant crossreactivity between pistachio and cashew nut belonging to the anacardiaceae family, and between pistachio nut and other dried fruits belonging to taxonomically unrelated botanical families. No relevant crossallergenicity was observed between pistachio nut and lolium and olea pollens. sodium dodecyl sulfate-polyacrylamide gel electrophoresis (SDS-PAGE) of a pistachio nut extract followed by immunoblotting analysis identified four IgE-binding bands with molecular weights of 34, 41, 52 and 60 kD.- - - - - - - - - - ranking = 2.5keywords = sensitivity (Clic here for more details about this article) |
8/139. Peanut allergy.Peanut allergy is acute and severe with symptoms of immediate hypersensitivity. This allergy is very common, affecting 1% of preschoolers. The incidence has increased with succeeding generations, and is possibly due to the increasing exposure of children to peanuts at a young age. diagnosis is via history, skin prick test, and serum IgE level. The mainstay of therapy is avoidance. Treatment of anaphylaxis includes epinephrine and antihistamines. Children usually will not outgrow this food allergy. Novel treatment with rush immunotherapy and enzyme-potentiated desensitization is not currently acceptable. We describe a 27-month-old Asian boy with a typical presentation of peanut hypersensitivity. A good understanding of the epidemiology of this illness is necessary for treatment and prevention.- - - - - - - - - - ranking = 1keywords = sensitivity (Clic here for more details about this article) |
9/139. Lethal or life-threatening allergic reactions to food.Fatal or life-threatening anaphylactic reactions to food occur in infants, children and adults. Atopic individuals with bronchial asthma and prior allergic reactions to the same food are at a particularly high risk, whereby even the mere inhalation of the allergenic food can be fatal. Not only peanuts, seafood and milk can induce severe, potentially lethal anaphylaxis, but indeed a wide spectrum of foods, according to the different patterns of food sensitivity in different countries. Foods with "hidden" allergens and meals at restaurants are particularly dangerous for patients with food allergies. Similarly, schools, public places and restaurants are the major places of risk. However, the main factor contributing to a fatal outcome is the fact that the victims did not carry their emergency kit with adrenaline (epinephrine) with them. In cases of death where food anaphylaxis is suspected, it is important for forensic reasons to preserve uneaten portions of the food in order to identify (hidden) allergens. It is also important to determine postmortem specific serum IgE, tryptase and histamine levels to document the anaphylaxis. There is a need to raise awareness of the diagnosis and treatment of anaphylaxis among doctors, those called upon to administer emergency medical care, and the public, and also to provide increased support for those with potentially fatal food allergies through the help of patients' organizations, and national and international medical societies. The food industry should ensure a policy of comprehensive labelling of ingredients so that even the smallest amount of potentially lethal foodstuffs can be clearly identified. Finally, the pharmaceutical industry should be persuaded to reintroduce an adrenaline inhaler onto the market.- - - - - - - - - - ranking = 0.5keywords = sensitivity (Clic here for more details about this article) |
10/139. Cinnamon-induced oral erythema multiformelike sensitivity reaction.BACKGROUND: erythema multiforme, or EM, is a hypersensitivity reaction to agents such as herpes virus, drugs or foods. Oral EM-like reactions may be induced by cinnamon. It is important for dentists to recognize this condition. CASE DESCRIPTION: The authors report an unusual case of cinnamon-induced oral EM-like reaction in an older female patient. The disease manifested itself as chronic extensive surface ulcerations and lip swelling. The patient was treated repeatedly with topical and systemic steroids but responded to them only temporarily. The patient was cured when the offending agent--cinnamon--was eliminated from her diet. CLINICAL IMPLICATIONS: Oral EM or EM-like reactions pose a diagnostic dilemma due to their varied etiologies and clinical manifestations. Correct diagnosis is essential for effective treatment. A negative skin test does not rule out an allergic reaction to food.- - - - - - - - - - ranking = 2.5keywords = sensitivity (Clic here for more details about this article) |
