“…3,4 Epistaxis is thought to be more common in cold and dry seasons because of decreased humidity and subsequent drying of the nasal mucosa, but this has not been documented in a large US sample. [1][2][3][4][5] Finally, studies have not separated traumatic and atraumatic epistaxis, though they may have distinct epidemiology and comorbidities.…”

“…Studies which examined the age distribution in epistaxis employed very different age groups, complicating the comparison [1,15,26,28]. The demonstrated slight increase in the incidence of right-sided epistaxis in our created groups may also be random because the differences are small and no clear trend is visible in the left or the bilateral nosebleed.…”

Lateralization of primary epistaxis was prospectively studied in 326 patients at Radebeul Elblandklinikum. The male-female-ratio was 1.3:1. A slight dominance of the right side (45% right vs. 39% left) was found in all patients. Further analyzed were the relationship to the localization of bleeding (anterior or posterior), the age and possible causes or risk factors. Nose bleeding from the posterior nasal portion appears to be statistically significantly higher than on both sides of anterior epistaxis. No statistically significant age dependence of laterality of epistaxis was observed in the age groups which we selected. However, nosebleed appears more frequently in women under the age of 50 years in both nostrils. With identified risk factors, idiopathic epistaxis occurs more frequently on the right side than does nosebleed. Mechanical trauma (intranasal sprays or nose picking) is a possible factor explaining the dominance of epistaxis on the right side, especially in idiopathic cases.

from the nose or epistaxis is a common presentation in the Ear, Nose and Throat (ENT) department. Various factors are responsible for nose bleed. It has been observed that 60% of the people experience at least one episode of epistaxis in their life time and 6% seek medical attention for this condition. 1 The incidence of epistaxis at the hospital is more during the dry and cold seasons. The frequency of admission is greatest in the autumn and winter months. 2 This seasonal variation correlates with fluctuations in the environmental temperature. 3 In the few reports found in literature, most research supports that there is a correlation between the frequency of epistaxis and at least one of the meteorological factors i.e. temperature, humidity and atmospheric pressure. However, the studies done on this topic are still few. There are various classifications for epistaxis. It is clinically classified as primary if there is no proven cause and secondary if there is a definite identifiable cause. It is also classified according to age as childhood and adult. Another way of classifying epistaxis is based on the site of bleeding, where the bleeding can be anterior or posterior in relation to the piriform aperture. 4 The causes of epistaxis are local and systemic. A careful history, physical examination and laboratory assessments are required for proper diagnosis. This study was done to observe the frequency of primary epistaxis at Nepal Medical College and Teaching Hospital (NMCTH) and its correlation to the seasonal variations of temperature and humidity. M A T E R I A L A N D M E T H O D S :Two hundred and sixty two consecutive patients attending ENT outpatient department of Nepal Medical College and Teaching Hospital (NMCTH) with nose bleed were included in the study. The study period was 2 years from August 2008 to July 2010. The study group comprised both hospitalised and not hospitalised patients. Nose bleed without any known cause or primary cases of epistaxis were included in this study. The exclusion criteria were patients with obvious causes for epistaxis, patients with trauma, coagulopathies, tumours and systemic causes. Out of 262 patients,105 cases were primary epistaxis. Daily temperature and humidity as documented by the Department of Hydrology and Meteorology of the Government of Nepal were recorded during this study period. The daily arithmetic averages (mean) of temperature and humidity were taken from which the mean monthly temperature and relative humidity were calculated. The frequency of epistaxis on a monthly basis was recorded and the seasonal variations were observed. Statistical analysis with Pearsons correlation coefficient was used to see the correlation between EPISTAXIS AND ITS RELATION WITH TEMPERATURE AND HUMIDITY O b j e c t i v e :The objective of this study was to observe the frequency of primary epistaxis and its relation with temperature and relative humidity. M a t e r i a l s a n d M e t h o d s :This was a prospective study which included 262 patients with epistaxis attending th...
