The allergist is frequently called on to evaluate patients after episodes of anaphylaxis to determine the cause and implement preventive measures that will reduce the patient's risk from future episodes. The etiology of anaphylaxis can be the result of numerous causes that may go undiagnosed
if a thorough evaluation is not performed. We present a 71-year-old man with no history of food allergy or atopy who presented to the emergency room and then our allergy clinic for evaluation after suffering anaphylaxis after a meal of grits and shrimp. The underlying diagnosis, which was
subsequently determined, requires a high index of suspicion and should be included in the differential diagnosis of any patient presenting with unexplained anaphylaxis.

ABSTRACT: Oral mite anaphylaxis is a new syndrome characterized by severe allergic symptoms occurring immediately after eating foods made with mite-contaminated wheat flour. This syndrome, which is more prevalent in tropical environments, is triggered more often by pancakes, and for that reason, it has been designated "the pancake syndrome." Because cooked foods are able to induce the symptoms, it has been suggested that thermoresistant allergens are involved in its pathogenesis. A variety of this syndrome can occur during physical exercise (dust mite ingestion-associated exercise-induced anaphylaxis).

ABSTRACT: Introduction: The infestation by mites of stored products is of great economic importance and public health, with consequences to human health. Objectives: To describe the mite species associated to food and stored products that cause implications to human health as well as to analyze the loss of quality and nutritional composition of infested food. Method: Literature review in LILACS-BIREME, SciELO and MEDLINE databases for publications in English, Portuguese and Spanish with the descriptors "mites", "foods", "storage mites", "store product mites", "dust mites", "quality control", "quality foods", "chemical composition", "chemistry", "allergens" and "health". There were identified 80 articles, but only 55 were related to the objectives of the study. Sixteen references were mentioned in the articles that were found after checked for relevance. Results and discussion: The activity of the mites causes loss of sanitary quality, weight and nutritional composition of the infested products, with great economic loss in the grain industry. Inhalation, ingestion or contact of mites, byproducts of metabolism and feces may sensitize susceptible individuals and cause asthma, allergic rhinitis, contact dermatitis, enteritis and lead to anaphylaxis. The monitoring of temperature and humidity is essential for the control of mites, as well as better conservation and hygiene of the units of grain storage.
