OBJECTIVE: Epistaxis is the most common ear, nose, and throat emergency observed in the @entity341 ( @entity341 ). An increased frequency of this condition has been observed during cooler months, but the results of available studies are controversial. The aim of this study was to investigate the seasonality and association of @entity1415 presentations to a large urban @entity341 with variations of air temperature and humidity. METHODS: This study was a retrospective case series. Information on all the @entity1 who presented for @entity1415 in the @entity341 of the Academic Hospital of Parma during the years 2003-2012 and ages >= 14 years were retrieved from the hospital data base, excluding those attributable to @entity130 . The chronologic data of all visits were associated with climate data (air temperature and humidity) by univariate linear regression analysis. RESULTS: Among the 819,596 @entity341 @entity1 seen throughout the observational period, 5404 were admitted for @entity1415 . Of these, 5220 were discharged from the @entity341 , whereas 184 (3.4%) needed hospital admission. A strong seasonality of @entity1415 was observed, with a peak during winter. A strong negative correlation was also found between the daily number of epistaxes and the mean daily temperature in the whole population as well as in @entity1 subgroups (those undergoing anticoagulant or antiplatelet therapy, or those with @entity101 , @entity74 , @entity1575 , or advanced @entity5 ). A weaker correlation was also found between air humidity and @entity1415 but only in certain subgroups. CONCLUSIONS: The results of this study provided a contribution to improve our understanding of the epidemiology of @entity1415 and for specific health policies that should also be planned by considering the seasonality of nosebleed.
