Background: Epistaxis is a common symptom in children. The effect of air pollution on epistaxis is not yet clear. Objectives: To explore the characteristics of pediatric epistaxis in Beijing and its correlation with air pollutants. Material and Methods: Data were collected from 2014 to 2017 in Otolaryngology Department of Capital Institute of Pediatrics. Children diagnosed with epistaxis with relevant information with the same period of municipal air pollutants’ concentration were compared. Results: The annual visits of epistaxis showed a bimodal trend. The incidence of epistaxis in infants was low, increased with age, reached the peak between the ages of 4 to 5, and then gradually decreased with age. In different age groups, male patients were more than females. From 2014 to 2017 in Beijing, particulate matter less than 2.5 μm in diameter (PM2.5), particulate matter less than 10 μm in diameter (PM10), sulfur dioxide (SO2), nitrogen dioxide (NO2), and carbon monoxide (CO) showed a downtrend, lower in summer than in the other 3 seasons. Ozone (O3) was significantly higher in 2016 and 2017, showed an increase trend in summer. The incidence of epistaxis was negatively correlated with PM2.5, PM10, SO2, NO2 and CO, which was positively correlated with O3 ( P < .05). Conclusions: Pediatric epistaxis in Beijing changes with age and has obvious seasonal variation. There are some correlations between air pollutants and the incidence of epistaxis in children.

“…Epistaxis is one of the most common conditions encountered in the department of otorhinolaryngology [1] . It is estimated that approximately 60% of the general population have experienced an episode of epistaxis at some point in https://doi.org/10.1016/j.anl.2020.07.012 0385-8146/© 2020 Oto-Rhino-Laryngological Society of Japan Inc.…”

Epistaxis is a commonly encountered condition; however, factors that have been associated with epistaxis are controversial. Although several previous studies have evaluated the relationship between meteorological factors and epistaxis, studies conducted in Korea has been nearly reported. We attempted to evaluate the meteorological factors associated with the frequency of patients presenting with epistaxis in a tertiary hospital. Methods:We retrospectively reviewed the medical records of patients presenting with spontaneous epistaxis in an urban tertiary medical center, during one year. Patients with a clear etiology for epistaxis (such as trauma, previous surgery) were regarded as cases of secondary epistaxis and were excluded from this study. Daily climatic data were collected from the website of Korea Meteorological Administration. Meteorological factors affecting the frequency of patients presenting with epistaxis were statistically analyzed.Results: Among 350 enrolled subjects, 219 were males and 131 were females, and the mean age was 44.94 ± 26.02 years. Univariate and multivariate regression analyses revealed that minimal temperature and mean wind speed were significant factors that affected the presence of patients presenting with epistaxis to the hospital. Furthermore, ordinal logistic regression analysis showed that decreases in minimal temperature and mean relative humidity were associated with a increase in the number of patients presenting with epistaxis. Conclusion:Minimal temperature and mean wind speed were significantly different between days with epistaxis and days without epistaxis patients presenting with epistaxis, and minimal temperature and mean relative humidity were associated with number of patients presenting with epistaxis. Our findings suggested that these meteorological factors might affect the spontaneous epistaxis in Seoul, Korea.

“…This association is plausible, given that low humidity may cause dryness of the nasal mucosa, which may lead to nasal bleeding [ 11 ]. Meanwhile, findings regarding the impact of temperature have been heterogenous, including some studies reporting a positive correlation between temperature and epistaxis in children [ 17 ], and other studies reporting the opposite association [ 18 ]. Results for other meteorological factors, such as air pressure, sunshine duration, and wind speed have also been inconsistent.…”

The impact of atmospheric concentration of particulate matter ≤10 μm in diameter (PM10) continues to attract research attention. This study aimed to evaluate the effects of meteorological factors, including PM10 concentration, on epistaxis presentation in children and adults. We reviewed the data from 1557 days and 2273 cases of epistaxis between January 2015 and December 2019. Eligible patients were stratified by age into the children (age ≤17 years) and adult groups. The main outcome was the incidence and cumulative number of epistaxis presentations in hospital per day and month. Meteorological factors and PM10 concentration data were obtained from the Korea Meteorological Administration. Several meteorological factors were associated with epistaxis presentation in hospital; however, these associations differed between children and adults. Only PM10 concentration was consistently associated with daily epistaxis presentation in hospital among both children and adults. Additionally, PM10 concentration was associated with the daily cumulative number of epistaxis presentations in hospital in children and adults. Furthermore, the monthly mean PM10 concentration was significantly associated with the total number of epistaxis presentations in the corresponding month. PM10 concentration should be regarded as an important environmental factor that may affect epistaxis in both children and adults.

Is the occurrence of pediatric epistaxis related to climatic variables?

Abstract: A positive correlation between the frequency of pediatric epistaxis existed for both temperature and air visibility. No significant correlation was found for humidity.
