Abstract
BACKGROUND AND OBJECTIVES Epistaxis is a common emergency for otorhinolaryngologists. Although the aetiological factors have been widely studied, they remain subject to debate. The role of meteorological variables has been discussed in recent years, but results have been inconsistent. Given a lack of prior data, the aim of our study was to identify the meteorological variables that influence the frequency of visits and hospital admission for epistaxis in a city with a cold semi-arid climate in Spain. METHODS Case-control study. CASES patients who attended the accident and emergency department of a secondary level hospital for epistaxis over a 9-year period (2011-2019). Controls were established by simple random sampling among emergency rooms visits in general (patients who attended the same centre over the same period of time). Sociodemographic, clinical and meteorological variables were all taken into account. RESULTS 2749 patients in the epistaxis group and 2764 in the control group. There were significant differences in the epistaxis group, with a higher proportion of male (62.85%) and older patients. Univariate and multivariate analysis revealed that the daily minimum temperature and maximum wind speed were factors significantly associated with the onset of epistaxis. In addition, logistic regression analysis showed that decreases in minimum temperature and increases in maximum wind speed were associated with an increase in epistaxis (p < 0.01). No association was found between hospital admission and the weather conditions. CONCLUSION Our findings suggest that low minimum temperatures and high wind speeds are associated with the number of visits to hospital accident and emergency departments for epistaxis, but not with hospital admission.

Abstract
INTRODUCTION AND OBJECTIVE Prior studies have provided variable results regarding environmental risk factors for epistaxis. These studies were conducted in varying climate zones, which may explain discrepancies in results. The objective of this study is to investigate correlations between season, temperature, and humidity on frequency of pediatric epistaxis across climate zones. METHODS Children seen in the outpatient setting for epistaxis were identified from the 2007-2010 IBM MarketScan database. Climate zones were assigned according to International Energy Conservation Code (IECC) classification, where temperature zones in the United States and territories were assigned on an ordinal scale from 1 (tropical) to 8 (subarctic), and humidity zones were categorized as moist, dry, or marine. The control population was a sample of all well-child visits matched by age and county. RESULTS We identified 184,846 unique children seen for epistaxis and 1,897,012 matched controls. Moderate temperature zones were associated with lower odds of epistaxis compared with the hottest and coldest zones. Humidity was associated inversely with epistaxis rates in moderate temperature zones but was not a significant predictor of epistaxis in climates with extreme heat. Additionally, summer was associated with lower odds of epistaxis compared to winter. Interestingly, however, there were significantly higher rates of cautery procedures during summer months, driven largely by increased procedures performed in clinic, as opposed to the operating room or emergency room. CONCLUSIONS Environmental risk factors for epistaxis vary by climate zone. The model presented reconciles prior reports and may allow for more personalized clinical management based on regional climate. LEVEL OF EVIDENCE 3 Laryngoscope, 134:1450-1456, 2024.

Int J Pediatr Otorhinolaryngol 2024; 176:111827. [PMID: 38128356 DOI: 10.1016/j.ijporl.2023.111827] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/04/2023] [Revised: 11/23/2023] [Accepted: 12/10/2023] [Indexed: 12/23/2023]
Abstract
OBJECTIVES Pediatric epistaxis is a multifactorial disease entity. The objective of this study is to determine the socioeconomic and air-quality contributions to pediatric epistaxis. The study also evaluates the utility of diagnostic lab work as a predictor of bleeding rates and need for operative intervention. METHODS A case series of pediatric patients treated in an outpatient Otolaryngology clinic at a tertiary care children's hospital in 2021 for epistaxis was performed. Patients with nasal bone trauma (n = 8), consult while inpatient (n = 7), and those with nasal masses (n = 2) were excluded; 181 patients met inclusion criteria. Demographic, clinical, socioeconomic, and air quality (tropospheric ozone, particulate matter) data were recorded. Associations with persistent bleeding and operative interventions were evaluated using logistic regression, Wilcoxon rank-sum, and Spearman rank correlation. RESULTS Of the 181 patients, 75 (41.4%) were female. Forty-six of 181 (25.4%) had associated allergic symptoms. Twenty-six patients had allergy testing; 14/26 (53.8%) of these had positive results. Re-bleeding was more common in those with allergic symptoms (OR: 2.42, 95% CI: 1.22-4.78, p = 0.01). Patients with re-bleeding lived in counties with more days with ozone over the US standard (median 5 days, range 0-32 days) compared with those with no re-bleeding (median 3 days, range 0-32 days, p = 0.007). There was also an association between the number of visits for re-bleed and percent below poverty level (ρ = 0.259, p = 0.03) as well as the number of days with particulate matter levels over the US standard (ρ = 0.343, p = 0.01). Coagulopathy was present in 9/54 (16.7%) patients, with the majority being Von Willebrand disease (5/54, 9.3%). Easy bruising was not significantly associated with positive lab results. CONCLUSIONS Environmental pollution, living in a zip code with more residents below the poverty level, and allergic rhinitis were positively associated with recurrent epistaxis. Understanding the geographic background of presenting patients may help direct workup and treatment options.

Abstract
OBJECTIVE To compare the risk of recurrent epistaxis between children treated with silver nitrate (SN) in the office or electrocautery (EC) in the operating room (OR). METHODS Patients aged 2-18 diagnosed with epistaxis (ICD R04.0) in 2018 and treated with SN or EC were retrospectively reviewed. Epistaxis laterality, history of nasal trauma, and personal or family history of a bleeding disorder were recorded. Patients with prior cautery or epistaxis secondary to a procedure were excluded. Recurrence was defined as initial encounter after cautery with documented epistaxis. Patients were followed up into 2022 to track onset of recurrence. Time to recurrence between SN and EC was compared with hazard curves with predictors for recurrence analyzed via Cox's proportional hazard regression. RESULTS Among 291 patients cauterized for epistaxis, 62 % (n = 181) received SN compared to 38 % (n = 110) who underwent EC. There was significantly higher risk of recurrence when treated with SN compared to EC (Hazard ratio 2.45, 95 % CI: 1.57-3.82, P < 0.0001). Median time to recurrence was not statistically different between techniques (6.39 months (SN) (IQR: 2.33, 14.82) vs. 4.11 months (EC) (IQR: 1.18, 20.86), P = 0.4154). Complication rates were low for both groups (1.16 % (SN) vs. 0 % (EC), P > 0.05). CONCLUSION Among patients with epistaxis, risk of recurrence is significantly higher in those cauterized with SN compared to EC. Time to recurrence is not significantly different between cautery techniques.

Abstract
BACKGROUND Hereditary hemorrhagic telangiectasia (HHT) is a rare autosomal dominant disorder characterized by recurrent epistaxis, telangiectasias, and visceral arteriovenous malformations. Individuals with HHT often identify low humidity and temperature as detrimental to epistaxis severity. We set out to assess the relationship between humidity and temperature on epistaxis severity in patients with HHT. METHODS Retrospective cross-sectional study at an academic hospital with an HHT center between July 1, 2014 and January 1, 2022. The primary outcome of this study was ESS. Pearson correlation analyses and multiple linear regression analyses were performed to test the association between weather variables and epistaxis severity scre (ESS). Results were reported as coefficient and 95% confidence interval (CI). RESULTS Four hundred twenty-nine patients were included in the analysis. Through a Pearson correlation analysis, neither humidity (regression coefficient = -0.01; 95% CI, -0.006 to 0.003; p = 0.50), daily low temperature (regression coefficient = 0.01; 95% CI, -0.011 to 0.016; p = 0.72), or daily high temperature (regression coefficient = 0.01; 95% CI, -0.004 to 0.013; p = 0.32) were significantly correlated with ESS. In a multiple linear regression analysis, adjusting for both daily low temperature and humidity, medications taken, demographics, and genotype, neither daily low temperature (regression coefficient = -0.02; 95% CI, -0.04 to 0.01; p = 0.14) nor humidity (regression coefficient = 0.01; 95% CI, -0.01 to 0.01; p = 0.64) were significantly associated with ESS. CONCLUSION We have shown in a large clinical sample that neither humidity nor temperature were strongly correlated with HHT patient epistaxis severity.

Abstract
Objectives: Little is known about the prevalence of epistaxis in children. Existing reports focus on hospitalized children or those presenting to an emergency department. To better understand pediatric epistaxis in clinical practice, we sought out a searchable, representative outpatient database and examined the incidence of epistaxis in children of different ages. Methods: A cross-sectional analysis of data from the National Hospital Ambulatory Medical Care Survey (NHAMCS) from the years 2007 to 2011 was performed. The NHAMCS is a Centers for Disease Control and Prevention-curated national sample of data from visits to non-federally employed office-based physicians and health centers. We queried the NHAMCS to determine the cumulative incidence of epistaxis in children of different age groups. The International Classification of Diseases Ninth Revision code 784.7 was chosen to identify epistaxis. Comparisons of rates were performed using the chi-squared test. A P-value of <.05 was considered statistically significant. Results: In total, 55,435,691 children [27,816,237 (50.2%) males, 55,435,691 (77.2%) white] were included. The overall cumulative incidence rate of epistaxis was 2.4/1000 children. Children in the 3- to 5-year range had the highest cumulative incidence of epistaxis (5.0/1000), followed by those in the 6 to 8 (3.0/1000), 9 to 11 (2.0/1000), 0 to 2 (1.9/1000), 12 to 14 (1.6/1000), and 15 to 17 (0.5/1000) year ranges (P < .001). Conclusion: Pediatric epistaxis is common in the office setting (2.4 per 1000 children)-and well above emergency department estimates (1.7 per 1000 people). Children between the ages of 3 to 5 years have the highest cumulative incidence. Epistaxis is sufficiently unusual in infants and the late teens that alternative causes for nasal bleeding should be included in the differential diagnosis.

Abstract
Introduction Environmental factors are closely associated with pediatric epistaxis. Whether this association differs according to age has not been previously reported. Therefore, we tried to evaluate the differences in associations between environmental factors and epistaxis in children of different ages. Methods A total of 20,234 patients with epistaxis who visited the hospital between January 1, 2002, and December 31, 2015, were enrolled in this study. The patients were divided into two groups according to their ages: preschool-aged (<6 years) and school-aged children (6-18 years). Daily, monthly, and yearly data on environmental factors were collected. We performed a stepwise logistic regression to identify the potential environmental risk factors for epistaxis in each age group. Results The mean number of epistaxis cases per month in both groups was highest in September. The cases were lowest in February in preschool-aged children and in November in school-aged children. Temperature, humidity, maximum wind speed, and sunshine duration were associated with epistaxis in preschool-aged children. Average wind speed, particulate matter (>10 μm diameter), temperature, humidity, sunshine duration, and sulfur dioxide concentration were associated with epistaxis in school-aged children. Conclusion This study indicates that the differences in environmental risk factors for epistaxis are associated with the patient's age.

Abstract
This research investigated Latinx and Indigenous Mexican caregivers' perspectives of the Salton Sea's environment (e.g., dust concentrations and other toxins) on child health conditions. The Salton Sea is a highly saline drying lakebed located in the Inland Southern California desert borderland region and is surrounded by agricultural fields. Children of Latinx and Indigenous Mexican immigrant families are especially vulnerable to the Salton Sea's environmental impact on chronic health conditions due to their proximity to the Salton Sea and structural vulnerability. From September 2020 to February 2021, we conducted semi-structured interviews and focus groups with a total of 36 Latinx and Indigenous Mexican caregivers of children with asthma or respiratory distress living along the Salton Sea. A community investigator trained in qualitative research conducted interviews in Spanish or Purépecha, an indigenous language spoken by immigrants from Michoacán, Mexico. Template and matrix analysis was used to identify themes and patterns across interviews and focus groups. Participants characterized the Salton Sea's environment as toxic, marked by exposure to sulfuric smells, dust storms, chemicals, and fires, all of which contribute to children's chronic health conditions (e.g., respiratory illnesses such as asthma, bronchitis, and pneumonia, co-presenting with allergies and nosebleeds). The findings have important environmental public health significance for structurally vulnerable child populations in the United States and globally.

Abstract
Background Epistaxis is a very common symptom. The occurrence of epistaxis may be affected by dry environments, but there are some differences among previous reports and this view is controversial. Objective We investigated the relationship between the number of epistaxes and daily average relative humidity. Methods Data on patients with epistaxis between March 2011 and February 2021 were collected from two hospitals. The daily average relative humidity was examined, and the change in the number of patients with epistaxis due to humidity was investigated using a generalized linear mixed model. Results A total of 4184 cases of epistaxis were identified. The number of epistaxis cases per day was significantly associated with the daily average relative humidity (p < 0.001). One percent increment in average relative humidity decreases the number of epistaxis cases per day by 1.1%. Conclusion A negative correlation was found to exist between daily average relative humidity and occurrences of epistaxis.

Abstract
The purpose of this study is to (1) to determine if treatment of underlying allergic rhinitis (AR) in children will affect epistaxis outcome, (2) to compare efficacy of three outpatient AR treatment regimens in epistaxis outcomes, and (3) to investigate potential factors in the pathogenesis of epistaxis with underlying AR. A single-blind randomized-controlled study was conducted in the Otolaryngology clinic in KK Women's and Children's Hospital. Sixty children aged below 18 years with underlying untreated AR, with first presentation of epistaxis, were randomized to three different AR treatments: treatment 1, antihistamine (20 patients); treatment 2, nasal steroid spray (20 patients); and treatment 3, both antihistamine and nasal steroid spray (20 patients). Epistaxis severity and frequency were assessed. Pre-treatment, 95% of patients within each of the three treatment groups described epistaxis symptoms. Post-treatment, there was improvement in epistaxis outcome (resolution of epistaxis) with 20% (4/20), 40% (8/20), and 60% (12/20) of patients in treatment groups 1 (antihistamine), 2 (nasal steroid spray), and 3 (combined therapy) respectively, who reported resolution of epistaxis. Treatment regimens containing nasal steroid spray resulted in greater improvement of epistaxis severity and frequency. Combined therapy (treatment 3) resulted in the best epistaxis outcome at 1-month follow-up. Majority (90%) reported nose-picking/rubbing behavior. CONCLUSIONS Intranasal corticosteroids are superior to oral antihistamines in relieving itch or rhinorrhea in AR. Intranasal corticosteroids may be important in treating epistaxis with underlying AR, because digital trauma from itch/rhinorrhea-related nose-picking/rubbing frequently leads to epistaxis. Results from this study will be important to primary and emergency physicians, community pediatricians, and pediatric allergists and otolaryngologists. WHAT IS KNOWN • Childhood epistaxis commonly co-exists with allergic rhinitis (AR), causing significant symptoms and distress to patients. • There are currently no studies reporti ng on epistaxis outcome aft er treatment of underlying AR. WHAT IS NEW • This is a single-blind randomized-controlled study of 60 children aged below 18 years with underlying untreated AR, with first presentation of epistaxis to a children's hospital in Singapore Patients were randomized to three different regimens to treat AR: treatment 1, antihistamine; treatment 2, nasal steroid spray; and treatment 3, both antihistamine and nasal steroid spray. • Treatment regimens containing nasal steroid spray improved epistaxis outcomes, with combined therapy of antihistamine and nasal steroid spray resulting in the best outcome for resolution of epistaxis among the three treatment regimens.

Differential effect of meteorological factors and particulate matter with ≤ 10-µm diameter on epistaxis in younger and older children. Sci Rep 2022; 12:21029. [PMID: 36470979 PMCID: PMC9723103 DOI: 10.1038/s41598-022-25630-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/12/2021] [Accepted: 12/02/2022] [Indexed: 12/12/2022] Open
Abstract
The differential effect of meteorological factors and air pollutants on pediatric epistaxis in younger and older children has not been evaluated. We evaluated the distribution of pediatric epistaxis cases between younger (0-5 years) and older children (6-18 years). Subsequently, we assessed and compared the effects of meteorological variables and the concentration of particulate matter measuring ≤ 10 μm in diameter (PM10) on hospital epistaxis presentation in younger and older children. This retrospective study included pediatric patients (n = 326) who presented with spontaneous epistaxis between January 2015 and August 2019. Meteorological conditions and PM10 concentration were the exposure variables, and data were obtained from Korea Meteorological Administration 75. The presence and cumulative number of epistaxis presentations per day were considered outcome variables. Air temperature, wind speed, sunshine duration, and PM10 concentration in younger children, and sunshine duration and air pressure in older children, significantly correlated with the presence of and cumulative number of epistaxis presentations per day. The PM10 concentration was not a significant factor in older children. Thus, meteorological factors and PM10 concentration may differentially affect epistaxis in younger (0-5-year-olds) and older (6-18-year-olds) children. Risk factors for pediatric epistaxis should be considered according to age.

Ahn EJ, Min HJ. Age-specific associations between environmental factors and epistaxis. Front Public Health 2022; 10:966461. [PMID: 36339143 PMCID: PMC9626808 DOI: 10.3389/fpubh.2022.966461] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/11/2022] [Accepted: 10/05/2022] [Indexed: 01/24/2023] Open
Abstract
Objective Several studies have demonstrated that environmental factors, such as meteorological factors and air pollutants, are closely associated with epistaxis. However, age-specific associations between environmental factors and epistaxis have not yet been evaluated. This study aimed to evaluate the associations between individual meteorological factors and air pollutants and epistaxis, by age. Study design A retrospective cohort study. Setting Records of patients covered by the Korean National Health Insurance Service who visited our hospital for epistaxis between January 1, 2002, and December 31, 2015, were retrospectively reviewed. Methods The 46,628 enrolled patients were divided into four age groups: age group 0 (<18 years, N = 19,580); age group 1 (18-40 years, N = 10,978); age group 2 (41-70 years, N = 13,395); and age group 3 (>70 years, N = 2,675). Cases of epistaxis and data on environmental factors were analyzed according to the day, month, and year. Stepwise logistic regression was performed to identify the environmental risk factors for epistaxis in each age group. Results Age group 0 had the highest number of patients with epistaxis, whereas age group 3 had the lowest. Relative humidity, temperature, concentrations of particulate matter (PM10) and sulfur dioxide, sunshine duration, and wind speed were significantly associated with the occurrence of epistaxis in the study population. However, analysis according to age group showed that the meteorological factors and air pollutants associated with epistaxis were different in each age group. Conclusion We suggest that the environmental risk factors for epistaxis should be differentially analyzed according to age.

Particulate Matter 10 (PM 10) Is Associated with Epistaxis in Children and Adults. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2021; 18:ijerph18094809. [PMID: 33946392 PMCID: PMC8124263 DOI: 10.3390/ijerph18094809] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 04/06/2021] [Revised: 04/27/2021] [Accepted: 04/28/2021] [Indexed: 11/20/2022]
Abstract
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.

Min SJ, Kang H, Kim KS, Min HJ. Minimal temperature, mean wind speed, and mean relative humidity are associated with spontaneous epistaxis in Seoul, Korea. Auris Nasus Larynx 2020; 48:98-103. [PMID: 32718810 DOI: 10.1016/j.anl.2020.07.012] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/28/2020] [Revised: 07/01/2020] [Accepted: 07/13/2020] [Indexed: 11/27/2022]
Abstract
OBJECTIVE 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.
