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
Hintergrund Die Inzidenz der Akutdiagnosen im Hals-Nasen-Ohren(HNO)-Bereich wird durch multiple Parameter beeinflusst, unter anderem meteorologische und saisonale Einflüsse. Durch ein besseres Verständnis dieser Faktoren könnten prophylaktische Ansätze entwickelt werden. Material und Methoden Über 6 Jahre erfolgte eine retrospektive Analyse aller Patienten, die sich aufgrund von typischen und weniger komplexen HNO-ärztlichen Krankheitsbildern wie Cerumen obturans, akuter Otitis externa und media, Nasenpyramidenfraktur, Epistaxis nasi, akuter Tonsillitis, akuter Rhinosinusitis oder eines Peritonsillarabszess in einer südwestdeutschen Universitätsklinik vorgestellt haben. Ergebnisse 32.968 Fälle wurden ausgewertet. Mit 24,5 % (8082 Fälle) war die Epistaxis nasi die häufigste Notfalldiagnose. Diese, wie auch die akute Otitis media und die akute Rhinosinusitis, traten signifikant häufiger in der kälteren Jahreshälfte auf. Es bestand keine signifikante Korrelation der Diagnose Nasenpyramidenfraktur mit besonderen Zeiten wie Feiertagen. Die akute Otitis externa korrelierte signifikant mit dem Zeitraum der Sommerferien. In Kalenderwoche 38 gab es die wenigsten und in der Kalenderwoche 52 die meisten Notfallvorstellungen. Schlussfolgerung Saisonale und meteorologische Faktoren spielen eine Rolle in der Krankheitsentstehung verschiedener HNO-ärztlicher Notfalldiagnosen.

[PMID: 34185016 PMCID: PMC8277359 DOI: 10.2196/28328] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2021] [Revised: 04/27/2021] [Accepted: 05/06/2021] [Indexed: 11/22/2022] Open
Abstract
Background The data retrieved with the online search engine, Google Trends, can summarize internet inquiries into specified search terms. This engine may be used for analyzing inquiry peaks for different medical conditions and symptoms. Objective The aim of this study was to analyze World Wide Web interest peaks for “ear pain,” “ear infection,” and “ear drops.” Methods We used Google Trends to assess the public online interest for search terms “ear pain,” “ear infection,” and “ear drops” in 5 English and non–English-speaking countries from both hemispheres based on time series data. We performed our analysis for the time frame between January 1, 2004, and December 31, 2019. First, we assessed whether our search terms were most relevant to the topics of ear pain, ear infection, and ear drops. We then tested the reliability of Google Trends time series data using the intraclass correlation coefficient. In a second step, we computed univariate time series plots to depict peaks in web-based interest. In the last step, we used the cosinor analysis to test the statistical significance of seasonal interest peaks. Results In the first part of the study, it was revealed that “ear infection,” “ear pain,” and “ear drops” were the most relevant search terms in the noted time frame. Next, the intraclass correlation analysis showed a moderate to excellent reliability for all 5 countries’ 3 primary search terms. The subsequent analysis revealed winter interest peaks for “ear infection” and “ear pain”. On the other hand, the World Wide Web search for “ear drops” peaked annually during the summer months. All peaks were statistically significant as revealed by the cosinor model (all P values <.001). Conclusions It can be concluded that individuals affected by otitis media or externa, possibly the majority, look for medical information online. Therefore, there is a need for accurate and easily accessible information on these conditions in the World Wide Web, particularly on differentiating signs and therapy options. Meeting this need may facilitate timely diagnosis, proper therapy, and eventual circumvention of potentially life-threatening complications.

Eur Arch Otorhinolaryngol 2021; 278:1653-1660. [PMID: 32968893 PMCID: PMC7510767 DOI: 10.1007/s00405-020-06362-4] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2020] [Accepted: 09/08/2020] [Indexed: 11/16/2022]
Abstract
OBJECTIVE To assess whether web-based public inquiries into pharyngitis-related search terms follow annual incidence peaks of acute pharyngitis in various countries from both hemispheres. METHODS Google Trends (GT) was utilized for systematic acquisition of pharyngitis-related search terms (sore throat, cough, fever, cold). Six countries from both hemispheres including four English (United Kingdom, United States, Canada, and Australia) and two non-English speaking countries (Austria and Germany) were selected for further analysis. Time series data on relative search interest for pharyngitis-related search terms, covering a timeframe between 2004 and 2019 were extracted. Following reliability analysis using the intra-class correlation coefficient, the cosinor time series analysis was utilized to determine annual peaks in public-inquiries. RESULTS The extracted datasets of GT proved to be highly reliable with correlation coefficients ranging from 0.83 to 1.0. Graphical visualization showed annual seasonal peaks for pharyngitis-related search terms in all included countries. The cosinor time series analysis revealed these peaks to be statistically significant during winter months (all p < 0.001). CONCLUSION Our study revealed seasonal variations for pharyngitis-related terms which corresponded to winter incidence peaks of acute pharyngitis. These results highlight the need for easily accessible information on diagnosis, therapy, and red-flag symptoms for this common disease. Accurately informed patients might contribute to a reduction of unnecessary clinic visits and potentially cutback the futile antibiotic overuse.

Annual trends in Google searches provides insights related to rhinosinusitis exacerbations. Eur Arch Otorhinolaryngol 2021; 279:213-223. [PMID: 33877434 PMCID: PMC8739168 DOI: 10.1007/s00405-021-06806-5] [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: 01/05/2021] [Accepted: 04/07/2021] [Indexed: 11/23/2022]
Abstract
Purpose Temporal trends of disease-specific internet searches may provide novel insights into seasonal dynamics of disease burden and, by extension, disease pathophysiology. The aim of this study was to define the temporal trends in rhinosinusitis-specific internet searches. Methods This was a cross sectional analysis of search volume for predefined search terms. Google trends was used to explore the volume of searches for five specific search terms related to rhinosinusitis: nose, mucus, sinus, sinusitis, chronic sinusitis, which were entered into Google web search between 2004 and 2019. Results were analyzed within search “context” which included temporally associated related searches. Relative search volume (RSV) was analyzed for English and non-English speaking countries from the Northern and Southern hemispheres. Analysis of seasonality was performed using the cosinor model. Results The five specific search terms were most related to rhinosinusitis-related search contexts, indicating that they were appropriately reflective of internet queries by patients for rhinosinusitis. The RSV for rhinosinusitis-related terms and more general search terms increased with each passing year indicating constant interest in rhinosinusitis. Cosinor time series analysis revealed inquiry peaks in winter months for all five specific rhinosinusitis-related search terms independent from the hemisphere. Conclusion Over a 15-year period, Google searches with rhinosinusitis-specific search terms consistently peaked during the winter around the world. These findings indirectly support the model of viral infection or exposure as the predominant cause of acute rhinosinusitis and acute exacerbations of chronic rhinosinusitis.

Abstract
Background Reports have suggested decreasing attention to CVD comorbidities during the COVID-19 pandemic, despite their association with worse virus-related outcomes. Using nowcasting tools, we sought to explore temporal trends in public interest by studying use of online search terms related to CVD comorbidities during the pandemic time period. Methods We queried Google Trends for recent (October 2019–October 2020) and seasonal (October 2016–October 2020) trends of search terms pertaining to cardiovascular-related behaviors or clinical care including clinical diagnostic and therapeutic-related terms. Additionally, we acquired data from Google Shopping Insights to explore consumer behavior. Data for search results in the US were compared using mean relative search volumes (RSV), tabulated by month. Results Online search interest in the terms “Exercise” and “Cigarettes” changed by +18.0% and −52.5%, respectively, comparing March–April with January–February 2020. Key terms related to CVD-related care, including diagnostic and therapeutic-related terms such as “Statin”, “Lipid profile”, “Low-density lipoprotein”, and “Hemoglobin A1C” declined to a four-year low in late March 2020 but regained pre-pandemic search query frequency by July 2020. Results were supported by Google Shopping analysis; for example, online consumer shopping-related searches for tobacco products reached at an all-year low after May 2020. Conclusion We report an increase in search interest for an overall healthier CVD-related lifestyle starting in March 2020, supported by online consumer shopping behavior. However, a months-long trough in public interest for CVD care-related search terms from March–May 2020 suggests a transient but substantial decrease in public focus on cardiovascular-related healthcare engagement. Future research is needed to understand if these mixed signals will persist into 2021 and how they potentially translate into real-world CVD-related event rates.

Abstract
BACKGROUND Corona Virus Disease 2019 (COVID-19) emerged in December 2019 and rapidly spread globally. Since there is still no specific treatment available, prevention of disease spread is crucial to manage the pandemic. Adequate public information is very important. To assess the optimal timing, the aim of this study was to investigate the association between web-based interest and new cases and deaths due to COVID-19. METHODS Web-based interest for queries related to 'coronavirus' was assessed between 1 January and 19 June 2020, using Google Trends in Australia, Brazil, Canada, Germany, Italy, South Africa, South Korea, Spain, United Kingdom, and the United States of America. Reliability analysis of the used search terms was performed using the intraclass correlation coefficient. To investigate the association between web-based interest and new COVID-19 cases or deaths, the relative search volume was analysed for correlation with new cases and deaths. RESULTS Reliability analysis revealed excellent reliability for COVID-19 search terms in all countries. Web-based interest peaked between 23 February and 5 April 2020, which was prior to the peak of new infections and deaths in most included countries. There was a moderate to strong correlation between COVID-19 related queries and new cases or new deaths. CONCLUSION Web-based interest in COVID-19 peaked prior to the peak of new infections and deaths in most countries included. Thus, monitoring public interest via Google Trends might be useful to select the optimal-timing of web-based disease-specific information and preventive measures.

Abstract
OBJECTIVES Acute laryngitis is a common disease with self-limiting nature. Since the leading cause is attributed to viral infections and thus self-limiting, many affected individuals do not seek professional medical help. However, because the major symptom of hoarseness imposes a substantial burden in everyday life, it might be speculated that web-based search interest on this condition follows incidence rates, with highest peaks during winter months. The aim of this study was to evaluate global public health-information seeking behaviour on laryngitis-related search terms. METHODS We utilized Google Trends to assess country-specific, representative laryngitis-related search terms for English and non-English speaking countries of both hemispheres. Extracted time series data from Australia, Brazil, Canada, Germany, the United Kingdom, and the United States of America, covering a timeframe between 2004 and 2019 were first assessed for reliability, followed by seasonality analysis using the cosinor model. RESULTS Direct comparisons revealed different, representative laryngitis-related search terms for English- and non-English speaking countries. Extracted data showed a trend of higher reliability in countries with more inhabitants. Subsequent graphical analysis revealed winter peaks in all countries from both hemispheres. Cosinor analysis confirmed these seasonal variations to be significant (all P < 0.001). CONCLUSION Public interest in laryngitis-related, online health information displayed seasonal variations in countries from both hemispheres, with highest interest during winter months. These findings emphasize the importance to optimize the distribution of reliable, web-based health education in order to prevent the spread of misinformation and to improve health literacy among general populations.
