Out of 2.513 clinical files of @entity56 @entity1 , we have found 200 pollen- @entity56 @entity1 , which represent 7.9% of the total @entity56 pathology in @entity1 , in our environment. We have studied in these 200, the most important epidemiological parameters and the influence that this can cause upon the characteristics of this disease. A male predominance has been found (70%) and it has been discovered that 52% of the total were born in spring (p less than 0.0005). An hundred per cent have shown grass-pollen sensitiveness and 52% have also shown other kinds of pollen @entity56 . It has been found familiar @entity56 background in 76.5% of the cases and in 32.5% familiar @entity56 history of @entity2023 . Unexpectedly, those who were in lack of familiar @entity56 history began their clinical symptoms earlier; 51.06% before 6 years of age (p less than 0.05). Other kinds of @entity56 manifestations were found in 51%, being respiratory symptoms the most important (35.5%), followed by the cutaneous (23.5%) and digestive ones (10.5%). Allergy to drugs was found in 10.5%. The more frequent symptoms of @entity2023 were in order of importance: @entity2490 (86.5%), @entity2024 (77%), @entity565 (48%), spasmodic cough (27.5%) and @entity110 (4%). @entity565 induced by grass-pollen @entity56 was equally suffered by the males as by the females, and this was more frequent among the @entity1 who had previously suffered from @entity1576 .
