RESUMO
This is a case report of a woman of 38 years old, studied and analyzed at the service of allergy and immunology with clinical manifestations of allergic rhinitis; studies of laboratory, cabinet and intradermal test were made to corroborate this diagnosis and the treatment with specific hyposensitization, oral antihistaminines and inhaled steroids was started. Two years later the patient referred urinary retention without important antecedents, so, a peripheral anticholinergic syndrome (PAS) was suspected, a urodynamic test study was carried out consisting in a uroflujometry, static and dynamic urethral profile, cystometry, flow pressure study and electromyography, which diagnosed low urinary obstruction (functional) and vesical sphincter pseudodysfunction, demonstrating the PAS associated with oral antihistamines.

BACKGROUND: The maize (zea mays) is considered one of the fundamental nutrients in the diet of the Mexican population. It can cause allergic reactions, according to reports from countries other than Mexico. OBJECTIVE: To know the participation of maize in the etiology of allergic disease and the incidence of positivity to its antigens by cutaneous tests, in Mexican patients. METHODS: Six hundred sixty-one patients were studied. There were obtained a complete clinical history and samples for laboratory tests, as well as the results of cutaneous tests. RESULTS: Of 661 patients, 56 (8.5%) manifested allergic symptoms attributable to maize, which correlated (p < 0.0001) with a positive cutaneous response to its antigens. Fifty (88%) of them worked with maize and had a significant relative risk value (RR=102). The remaining six patients did not work with maize, four of them were included in the group who had a positive response for both allergens (n = 25), and two in that one with positive response for only one of these allergens (n = 100). CONCLUSIONS: The low frequency (8.5%) to which the allergic disease was attributed to maize, and the strong association (88%) with workers of maize induce us to consider the influence of some differences concerning to the cereal, such as physical characteristics, years and frequency to contact with, and specially to its entrance route. In fact, it plays an important role in the development of either toleragenic or immunogenic response to an antigen.
