[The cutaneous manifestations in food allergies]

A study on cutaneous signs in food allergies was perform on a number of patients admitted in the dermatology clinic. The clinical diagnosis is based on a critical anamnesis on the alimentary origin, laboratory findings and therapeutical test. The different alimentary behavior in the urban areas, in association with stress, generates a higher frequency of food allergies in these areas, comparative with the incidence in the rural areas. The dietary structure in the 3rd and 4th trimester, with an abundance of meat and meat products, sugar products and alcoholic's drinks, is an explanation for the higher incidence of food allergies in this period of the year. These foods are on the origin of 45.3% of all the food allergies and the middle age group (36-40 years) is most affected. The majority of patients (59%) had a very short time between ingestion of food and the debut of symptomatology, but the evolution was favorable.
