Meteorological factors potentially cause spontaneous epistaxis in Xining area
Abstract
Objective To identigy the relationship between the morbidity of epistaxis and the meteorological factors in Xining, Qinghai province. Methods The medical records of patients with spontaneous epistaxis from the department of otorhinolaryngology emergency and outpatient department from Jan 1, 2017 to Dec 31, 2017 were collected and retrospectively reviewed. Patients with a clear etiology for the epistaxis (traumatic, iatrogenic, tumor, foreign body,coagulopathic illness) were excluded. The monthly climatic data were collected from the Xining Meteorological Administration. The relationship between the incidence of epistaxis and meteorological factors were statistically analyzed with Pearson's correlation co-efficient. Results There were 1 219 cases of epistaxis in a year period. A significant negative correlation was found between temperature and epistaxis morbidity (P＜0.05). A significant negative correlation between humidity and epistaxis was also found(P＜0.05). Conclusions This is the first report about potential relationship beween meteorological factors and epistaxis in Xining. The spontaneous epistaxis is potentially attributed to meteorological factors in Xining.
