Summary
Public interest in nosebleeds (epistaxis) peaks in winter, according to Google search trends. This seasonal pattern was observed globally, highlighting a consistent public concern during colder months.
Area of Science:
- Otolaryngology
- Public Health
- Digital Epidemiology
Background:
- Epistaxis (nosebleeds) is a common ENT emergency.
- Seasonal variations in epistaxis incidence are suspected but lack conclusive evidence.
- Understanding public interest can inform health resource allocation.
Purpose of the Study:
- To analyze global public search interest in epistaxis using Google Trends.
- To investigate seasonal patterns in online searches for nosebleed information.
- To assess the correlation between search volume and time of year.
Main Methods:
- Systematic collection and comparison of "Epistaxis"-related search terms via Google Trends.
- Analysis of relative search volumes from 2004-2019 for key countries.
- Application of cosinor time series analysis to identify significant seasonal trends.
Main Results:
- Graphical analysis showed clear seasonal variations in search interest, peaking in winter for most countries.
- Cosinor analysis confirmed these seasonal patterns were statistically significant (p < 0.001).
- Seasonal trends were evident in both Northern and Southern Hemisphere countries.
Conclusions:
- Public online search behavior for epistaxis exhibits distinct seasonal patterns, with heightened interest during winter.
- These findings suggest a potential link between environmental factors and nosebleed incidence.
- Further research is recommended to explore the causal relationship between environmental factors and epistaxis seasonality.

Epistaxis, or nosebleeds, occurs when small, swollen blood vessels in the nasal mucous membrane rupture. Typically, the anterior septum is the primary site of occurrence.
Etiology
Possible causes of this condition include high blood pressure, trauma, low humidity, upper respiratory tract infections, allergies, foreign bodies, nasal inhalation of corticosteroids or illicit drugs, excessive use of decongestant nasal sprays, facial or nasal surgery, anatomic malformation, tumors, or systemic...

1.1K
Thoracentesis(Thoracocentesis), commonly known as pleural tap, is a medical procedure where a 22 gauge needle is inserted into the pleural space, the area between the lung and chest wall. This procedure is commonly performed to diagnose or treat various respiratory disorders.
Description
Excess pleural fluid or air may accumulate in some respiratory disorders in the thoracic cavity. To treat pleural effusion, a physician conducts thoracentesis by carefully piercing the chest wall and entering...
