Clinical Characteristics and Risk Factors for Allergic Rhinitis in Children with Epistaxis

Background

Epistaxis is frequently observed in children with allergic rhinitis. However, few studies have addressed the clinical characteristics and risk factors for allergic rhinitis in children with epistaxis. This study aimed to describe the factors associated with allergic rhinitis in children with epistaxis.

Methods

In total, we recruited 80 children (aged 3-14 years) who presented with epistaxis at a tertiary hospital between January 2014 and January 2022. The follow-up duration was at least 3 months, and we performed a multivariate logistic regression analysis to identify the risk factors for allergic rhinitis.

Results

Among the 80 children examined, 57 (71.25%) had allergic rhinitis. Epistaxis mainly occurred in autumn in children with allergic rhinitis; in contrast, it mostly occurred in summer in children without it (P = 0.029). Mites are common allergens for allergic rhinitis in children with epistaxis; the univariate analysis revealed significant differences between allergic-rhinitis group and nonallergic-rhinitis group in the number of allergens (P  <  0.001) and total IgE (P  <  0.001). The difference in severity of nasal symptoms between the two groups was statistically significant and included nasal obstruction (P  <  0.001), rhinorrhea (P  <  0.001), sneezing (P  <  0.001), and nasal itching (P  <  0.001). After adjusting for potential confounders, the severity of rhinorrhea symptoms was found to be associated with an increased risk of allergic rhinitis in children with epistaxis (odds ratio: 3.86; 95% confidence interval: 1.61-9.26; P = 0.003).

Conclusions

Observing the onset season, number of allergens, total IgE, and nasal symptoms in cases of epistaxis could suggest the presence of associated allergic rhinitis and reduce the number of missed diagnoses; antiallergic drugs could help control epistaxis in these cases.

Age-specific associations between environmental factors and epistaxis

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.

Epistaxis in a Pediatric Outpatient Clinic: Could It be an Alarming Sign?

Introduction Epistaxis is a common presentation among children.

Objective To investigate the suitability of a simple tool of assessment for patients with epistaxis that could guide in subgrouping those with possible bleeding tendencies who may need further assessment.

Methods Children who presented to a tertiary outpatient clinic with epistaxis of an unknown cause were recruited. They underwent thorough clinical assessment and answered the pediatric bleeding questionnaire and the epistaxis severity score. All patients underwent complete blood count as well as coagulation profile, and confirmatory diagnostic tests were performed as needed.

Results Among the 30,043 patients who presented to the outpatient clinic over a year, 100 children had epistaxis, with an estimated annual frequency of 1 in 300. A total of 84% of the patients were younger than 12, and nearly half of these were younger than 6 years. Seventy-six patients had recurrent epistaxis, and 12 had systemic comorbidities. A significant higher percentage of patients presented with epistaxis in the hot months of the year. A total of 90% of the patients presented anterior bleeding, and the majority were treated with nasal compression only. Forty-three patients presented with epistaxis only; 37 of them were diagnosed as idiopathic epistaxis, and 6 had local causes. Fifty-seven patients presented with other bleeding manifestations, 47 of whom had a definite bleeding disorder and the other 10 had undiagnosed bleeding tendency. Those with other bleeding manifestations showed a higher frequency of positive family history of epistaxis; of being referred from a primary care physician; of having alarming low platelet count, and of presenting less seasonal variability. A bleeding score ≥ 2 showed significant value in suspecting an underlying systemic pathology as a cause of epistaxis.

Conclusion The pediatric bleeding questionnaire is a useful and simple tool in the identification of pediatric patients who need further diagnostic testing to detect any underlying bleeding tendency.

Particulate Matter 10 (PM10) Is Associated with Epistaxis in Children and Adults

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.

Geographic Variation in Epistaxis Interventions Among Medicare Beneficiaries

OBJECTIVES

To quantify the utilization of epistaxis procedures in the elderly population and assess whether the geographic variability of these procedures is associated with hypertension and direct oral anticoagulant (DOAC) use.

METHODS

A cross-sectional study was performed on publicly available Medicare procedure and beneficiary data from 2013 to 2016 for all epistaxis procedures categorized by Common Procedural Terminology (CPT). Epistaxis procedures were analyzed by state, complexity, and provider type. Pearson's correlation coefficient was calculated.

RESULTS

Over 4 years, 2 19 827 epistaxis procedures were performed on Medicare patients, 44.3% of which were categorized as simple (control of nasal hemorrhage: anterior simple or posterior primary). Otolaryngologists performed 92.6% of all epistaxis procedures. The frequency of epistaxis procedures performed by state ranged from 0.99 procedures per 10 000 Medicare beneficiaries (PP10K) in Hawaii to 25.7 PP10K in New Jersey. The percentage of epistaxis interventions categorized as complex (anterior complex, posterior subsequent, with nasal endoscopy, or open procedures) in each state varied from 0% in North Dakota to 72.6% in Hawaii. Epistaxis procedure utilization was weakly correlated with the prevalence of hypertension (R² = 0.08, P = .04) and higher percentage of DOAC among all anticoagulants prescribed (R² = 0.08, P = .04) in a state's Medicare population. Utilization of complex epistaxis interventions was not correlated with the prevalence of hypertension or DOAC use.

CONCLUSIONS

Otolaryngologists perform the vast majority of epistaxis procedures in the Medicare population. However, practice patterns vary across the United States. Hypertension and DOAC use are weakly associated with the utilization of epistaxis interventions.

Epidemiologic and Outcome Analysis of Epistaxis in a Tertiary Care Center Emergency Department

Background

The association between hypertension and recurrent epistaxis is controversial. The objective of this study is to examine the factors associated with recurrent epistaxis visits to the emergency department (ED) and establish an otolaryngology (ENT [ear, nose, and throat]) consult algorithm to optimize treatment and minimize unnecessary consultation.

Methods

A retrospective review of 100 patients presenting to the ED for epistaxis requiring ENT consult from 2013 to 2018 was conducted. Patient demographics, comorbidities, epistaxis etiology, blood pressure measurements during admission, and treatment methods were analyzed. Patient charts were reviewed for ED admissions, complications, and procedures. A consult algorithm was subsequently devised and retrospectively applied to our cohort.

Results

Patients who required more than one ED visit for epistaxis were more often males (77.8% vs 49.3%, P = .01), required posterior packing (51.9% vs 17 .8%, P < .001), and had more comorbid hypertension (66.7% vs 38.4%, P = .01) compared to patients who had 1 visit. Compared to patients presenting during summer and fall (May–October), patients presenting during winter and spring (November–April) were more often treated for anterior epistaxis with Surgicel®/Surgifoam® rather than posterior nasal packing (57.4% vs 37.0%, P = .04). Application of our consult algorithm decreased consultation by 78% and liberated 58.5 hours of ENT resident time.

Conclusion

Patients with recurrent epistaxis tended to be male and had more comorbid hypertension. Further prospective studies are warranted to ascertain the factors associated with recurrent epistaxis. Our consult algorithm for epistaxis helped reduce unnecessary ENT consultation and facilitated reallocation of valuable resident work hours.

Doctor Google: Correlating internet search trends for epistaxis with metropolitan climates

OBJECTIVE

Variation in weather patterns is often cited as a risk factor for epistaxis although robust studies investigating specific climate factors are lacking. As society is increasingly utilizing the Internet to learn more about their medical conditions, we explore whether Internet search activity related to epistaxis is influenced by fluctuations in climate.

METHODS

Internet search activity for epistaxis-related search terms during 2012-2017 were extracted from Google Trends and localized to six highly populated cities in the US: New York, New York; Los Angeles, California; Chicago, Illinois; Houston, Texas; Philadelphia, Pennsylvania; and Atlanta, Georgia. Data were compared to local average monthly climate data from the National Centers for Environmental Information for the same time period.

RESULTS

Spearmen correlations (r) were statistically strongest for dew point temperature (r_NewYork = -0.82; r_Philadelphia = -0.74; r_Chicago = -0.65; r_Atlanta = -0.49, r_LosAngeles = -0.3). This was followed closely by relative humidity (r_NewYork = -0.63; r_Philadelphia = -0.57; r_LosAngeles = -0.44; r_Atlanta = -0.42; r_Houston = -0.40) and average temperature (r_NewYork = -0.8; r_Philadelphia = -0.72; r_Chicago = -0.62; r_Atlanta = -0.45). Overall, correlations were most significant and predictable for cities with the greatest seasonal climate shifts (New York, Philadelphia, and Chicago). The weakest environmental factor was barometric pressure, which was found to be moderately positive in Atlanta (r_barometric = 0.31), Philadelphia (r_barometric = 0.30) and New York (r_barometric = 0.27).

CONCLUSIONS

Google Trends data for epistaxis-related search activity responds closely to climate patterns in most cities studied, thus underscoring the potential utility of Internet search activity data as a resource for epidemiologic study and for the identification of at risk populations.

The role of meteorologic factors and air pollution on the frequency of pediatric epistaxis

Fluctuations in atmospheric temperature, humidity, and air pollution are associated with the incidence of epistaxis. To date, no study in the literature has evaluated the effect of air pollution and meteorologic conditions on the pediatric population. We aimed to evaluate the effect of meteorologic factors and air pollution on the frequency of epistaxis in children. Children presenting to an outpatient clinical setting at a tertiary care hospital during a 5-year period (July 1, 2009, to June 30, 2014) and diagnosed with epistaxis formed the study population. Daily temperature and humidity parameters and average daily atmospheric water vapor pressure, average daily concentration of particulate matter <10 μm in diameter, and sulfur dioxide readings were obtained. The distribution of daily parameters was analyzed. Of the 1,559 children with the primary diagnosis of epistaxis, data from 1,330 children were analyzed after excluding patients with coexisting pathologies. Positive correlations were found between the frequency of epistaxis and both the average daily temperature and the difference between the maximum and minimum daily temperature. There was a negative correlation between the epistaxis frequency and the average daily humidity, the difference between the maximum and minimum daily humidity, the average daily concentration of particulate matter, and the sulfur dioxide levels. Our findings suggest that epistaxis in children is related to high temperatures and low humidity.

Demographic, Seasonal, and Geographic Differences in Emergency Department Visits for Epistaxis

Objective

To determine the demographics and seasonal and geographic variation of epistaxis in the United States.

Study Design

Retrospective cohort analysis based on data from Medicare claims.

Setting

Emergency department visits.

Subjects and Methods

We used a 5% sample of Medicare data from January 2012 to December 2012. Our cohort included patients with an incident diagnosis of epistaxis during a visit to the emergency department, excluding those with a diagnosis in the prior 12 months. Demographics included age, sex, race, and ethnicity. We compared the rate of emergency department visits for epistaxis by geographic division and individual states.

Results

In the 5% sample of Medicare data, 4120 emergency department visits for incident epistaxis were identified in 2012. Our results showed an increase in the emergency department visits for epistaxis with age. Compared with patients <65 years old, patients who were 66 to 76, 76 to 85, and >85 years old were 1.36 (95% confidence interval [95% CI], 1.23-1.50), 2.37 (95% CI, 2.14-2.62), and 3.24 (95% CI, 2.91-3.62) more likely to present with epistaxis, respectively. Men were 1.24 (95% CI, 1.17-1.32) times more likely to present with epistaxis than women. Blacks were 1.23 (95% CI, 1.10-1.36) times more likely to present with epistaxis when compared with non-Hispanic whites. Epistaxis emergency department visits were 40% lower in the summer months versus winter. The seasonal variation was more pronounced in the northern versus southern United States.

Conclusion

Emergency department visits for epistaxis increase with age and appear to be seasonal, with a more pronounced variation in the northern versus southern United States.

Influence of air temperature variations on incidence of epistaxis

OBJECTIVE

Epistaxis is the most common ear, nose, and throat emergency observed in the emergency department (ED). 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 epistaxis presentations to a large urban ED with variations of air temperature and humidity.

METHODS

This study was a retrospective case series. Information on all the patients who presented for epistaxis in the ED 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 trauma. 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 ED patients seen throughout the observational period, 5404 were admitted for epistaxis. Of these, 5220 were discharged from the ED, whereas 184 (3.4%) needed hospital admission. A strong seasonality of epistaxis 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 patient subgroups (those undergoing anticoagulant or antiplatelet therapy, or those with hypertension, inherited bleeding disorders, liver cirrhosis, or advanced malignancy). A weaker correlation was also found between air humidity and epistaxis but only in certain subgroups.

CONCLUSIONS

The results of this study provided a contribution to improve our understanding of the epidemiology of epistaxis and for specific health policies that should also be planned by considering the seasonality of nosebleed.

An improvement in the appointment scheduling in primary health care centers using data mining

An optimal resource management in health care centers implies the use of an appropriate timetabling scheme to schedule appointments. Timetables of health centers are usually divided into time slots whose duration is equal to time required for clinical attendance. However doctors perform a series of tasks that are not always clinical in nature: issuing prescriptions or prescribing sick leave certificates. In this sense the time spent in attending a clinical or an administrative matter is different. This last required less time to attend the patient. This study is focused in the administrative task. A predictive model is generated to provide daily information on how many patients will go to the health center for an administrative issue. The accuracy of the model is less than 4,6 % absolute error and the improvement in scheduling appointments is a time saving of 21,73 %.

Selective endovascular embolization for refractory idiopathic epistaxis is a safe and effective therapeutic option: technique, complications, and outcomes

Epistaxis generally responds to conservative management, but a more invasive approach, such as superselective embolization, is sometimes justified. We report our experience with endovascular procedures in 19 patients from 2002 to 2011 for the treatment of refractory idiopatic posterior epistaxis. The sphenopalatine artery and distal internal maxillary arteries were embolized in all patients. Unilateral embolization was performed in 12 patients (63%), bilateral embolization in seven (37%). Additional embolization of the descending palatine artery was performed in eight patients (42%) and embolization of the facial artery and palatine arteries in four (21%). In one patient the distal ophthalmic artery was embolized with n-butyl cyanoacrylate. No minor or major complications occurred in relation to the embolization procedures. The average hospital stay was 11.1±8.6 days, including an average 5.2±3.4 days after embolization. Average follow-up after discharge was 21.3±25.7 months. Superselective endovascular embolization proved safe and effective in controlling idiopathic epistaxis, refractory to other maneuvers.
