Performance and Consistency of ChatGPT-4 Versus Otolaryngologists: A Clinical Case Series

OBJECTIVE

To study the performance of Chatbot Generative Pretrained Transformer-4 (ChatGPT-4) in the management of cases in otolaryngology-head and neck surgery.

STUDY DESIGN

Prospective case series.

SETTING

Multicenter University Hospitals.

METHODS

History, clinical, physical, and additional examinations of adult outpatients consulting in otolaryngology departments of CHU Saint-Pierre and Dour Medical Center were presented to ChatGPT-4, which was interrogated for differential diagnoses, management, and treatment(s). According to specialty, the ChatGPT-4 responses were assessed by 2 distinct, blinded board-certified otolaryngologists with the Artificial Intelligence Performance Instrument.

RESULTS

One hundred cases were presented to ChatGPT-4. ChaGPT-4 indicated a mean of 3.34 (95% confidence interval [CI]: 3.09, 3.59) additional examinations per patient versus 2.10 (95% CI: 1.76, 2.34; P = .001) for the practitioners. There was strong consistency (k > 0.600) between otolaryngologists and ChatGPT-4 for the indication of upper aerodigestive tract endoscopy, positron emission tomography and computed tomography, audiometry, tympanometry, and psychophysical evaluations. Primary diagnosis was correctly performed by ChatGPT-4 in 38% to 86% of cases depending on subspecialty. Additional examinations indicated by ChatGPT-4 were pertinent and necessary in 8% to 31% of cases, while the treatment regimen was pertinent in 12% to 44% of cases. The performance of ChatGPT-4 was not influenced by the human-reported level of difficulty of clinical cases.

CONCLUSION

ChatGPT-4 may be a promising adjunctive tool in otolaryngology, providing extensive documentation about additional examinations, primary and differential diagnoses, and treatments. The ChatGPT-4 is more effective in providing a primary diagnosis, and less effective in the selection of additional examinations and treatments.

The impact of different anticoagulants and antiplatelets regimens on acute epistaxis outcomes

BACKGROUND

The impact of anticoagulants (AC) and antiplatelets (AP) on the management of acute epistaxis remains unclear. This study investigated the association between AC/AP therapy and treatment outcomes in patients with acute epistaxis.

METHODOLOGY

A retrospective analysis of patients presented to the otolaryngology emergency room with acute epistaxis (2014-2022). Patients were categorized based on their regular medications: AP, dual AP therapy (DAPT), new oral anticoagulants (NOAC), vitamin K antagonists (VKA), or no regular AC/AP use (control group). Outcome measures included rates of minor interventions (chemical or electrical cautery, nasal tamponade), major interventions (endoscopic ligation, embolization), recurrent emergency department visits, admission rates, and duration.

RESULTS

786 patients were included with an average follow-up period of 52.56 ± 20.4 months. Compared to the control group, patients on AP, DAPT, or VKA had significantly higher rates of minor interventions (63.1% vs. 74.4%, 79.6%, and 77.3%, respectively, p < 0.05). DAPT users exhibited a higher rate of major interventions than the control (5.6% vs. 1.3%, p = 0.053). NOAC users showed no significant difference in minor interventions compared to control and required no major interventions. Both NOAC and VKA users had significantly higher rates of recurrent epistaxis events and prolonged hospitalization compared to the control (p < 0.01 and p < 0.05, respectively).

CONCLUSIONS

NOAC demonstrated more favorable outcomes than VKA in patients with acute epistaxis, and DAPT use was associated with an increased need for major interventions. These findings suggest a more conservative approach in NOAC users than other AC/AP agents.

Maxillofacial haemorrhagic symptoms in emergency department patients: impact of antithrombotics

PURPOSE

To investigate the effect of antithrombotics on the occurrence of maxillofacial haemorrhagic symptoms, and to determine if these haemorrhagic symptoms are predictors of maxillofacial fractures.

METHOD

A prospective cohort study was conducted of consecutive patients with maxillofacial trauma who had been admitted to the emergency department of four hospitals in the Netherlands. This study compared five haemorrhagic symptoms (peri-orbital haematoma, raccoon eyes, epistaxis, subconjunctival ecchymosis, and intra-oral haematoma) between patients not-using (NUA) and using (UA) of antithrombotics, and whether these maxillofacial haemorrhagic symptoms served as predictors for maxillofacial fractures.

RESULTS

Out of the 1005 patients, 812 (81%) belonged to the NUA group, and 193 (19%) to the UA group. UA patients exhibited higher frequencies of peri-orbital hematoma (54% vs. 39%, p < 0.001), raccoon eyes (10% vs. 5%, p = 0.01), and subconjunctival ecchymoses (16% vs. 7%, p < 0.001). In NUA, peri-orbital hematoma (OR = 2.5, p < 0.001), epistaxis (OR = 4.1, p < 0.001), subconjunctival ecchymosis (OR = 2.3, p = 0.02), and intra-oral hematoma (OR = 7.1, p < 0.001) were significant fracture predictors. Among UA, peri-orbital hematoma (OR = 2.2, p = 0.04), epistaxis (OR = 5.4, p < 0.001), subconjunctival ecchymosis (OR = 3.7, p = 0.008), and intra-oral hematoma (OR = 22.0, p < 0.001) were significant fracture predictors.

CONCLUSION

Maxillofacial haemorrhagic symptoms were observed more frequently in the UA group than in the NUA group. However, in both groups, maxillofacial haemorrhagic symptoms appear to be predictors of maxillofacial fractures. Caution is warranted in attributing these symptoms solely to antithrombotic use during emergency department assessments.

ChatGPT vs UpToDate: comparative study of usefulness and reliability of Chatbot in common clinical presentations of otorhinolaryngology-head and neck surgery

PURPOSE

The usage of Chatbots as a kind of Artificial Intelligence in medicine is getting to increase in recent years. UpToDate® is another well-known search tool established on evidence-based knowledge and is used daily by doctors worldwide. In this study, we aimed to investigate the usefulness and reliability of ChatGPT compared to UpToDate in Otorhinolaryngology and Head and Neck Surgery (ORL-HNS).

MATERIALS AND METHODS

ChatGPT-3.5 and UpToDate were interrogated for the management of 25 common clinical case scenarios (13 males/12 females) recruited from literature considering the daily observation at the Department of Otorhinolaryngology of Ege University Faculty of Medicine. Scientific references for the management were requested for each clinical case. The accuracy of the references in the ChatGPT answers was assessed on a 0-2 scale and the usefulness of the ChatGPT and UpToDate answers was assessed with 1-3 scores by reviewers. UpToDate and ChatGPT 3.5 responses were compared.

RESULTS

ChatGPT did not give references in some questions in contrast to UpToDate. Information on the ChatGPT was limited to 2021. UpToDate supported the paper with subheadings, tables, figures, and algorithms. The mean accuracy score of references in ChatGPT answers was 0.25-weak/unrelated. The median (Q1-Q3) was 1.00 (1.25-2.00) for ChatGPT and 2.63 (2.75-3.00) for UpToDate, the difference was statistically significant (p < 0.001). UpToDate was observed more useful and reliable than ChatGPT.

CONCLUSIONS

ChatGPT has the potential to support the physicians to find out the information but our results suggest that ChatGPT needs to be improved to increase the usefulness and reliability of medical evidence-based knowledge.

Restarting Antithrombotic Therapies After Endoscopic Sinus Surgery: A Systematic Review

OBJECTIVES

Antithrombotic therapies, comprised of both anticoagulant and antiplatelet agents, are routinely paused prior to endoscopic sinus surgery (ESS) to reduce the risk of perioperative hemorrhage. At present, no clear guidelines exist to guide otolaryngologists on when to resume these agents after ESS. Our goal was to systematically review the existing literature related to this topic.

METHODS

Following Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, we systematically queried the PubMed, Embase, Ovid, Web of Science, Cochrane, and CINAHL databases to identify publications reporting on antithrombotic and antiplatelet therapy in the context of ESS. The primary outcomes we sought were recommendations on the timing of antithrombotic therapy resumption after ESS.

RESULTS

Of the 104 unique articles identified, all were screened for relevance by 2 independent reviewers based on title and abstract, 20 underwent full-text review, and 6 met inclusion criteria for analysis. Of these, 3 were literature reviews, 2 were case-control studies, and 1 was a cohort study. All publications discussed when to pause antithrombotic therapy prior to surgery while only 3 articles discussed resumption of these agents. Recommendations were mixed.

CONCLUSION

A paucity of literature exists on the resumption of antithrombotic therapies after ESS. As a major determining factor in patient morbidity, guideline-based resumption of these therapies is needed.

Posterior epistaxis management: review of the literature and proposed guidelines of the hellenic rhinological-facial plastic surgery society

PURPOSE

Posterior epistaxis is a common emergency in ENT practice varying in severity and treatment. Many management guidelines have been proposed, all of which are a product of retrospective analyses due to the nature of this pathology, as large-scale double-blind studies are impossible-even unethical-to conduct. The purpose of this review is to perform a thorough analysis and comparison of every treatment plan available and establish guidelines for the best possible outcome in accordance to every parameter studied. Given the extensive heterogeneity of information and the multitude of studies on this topic, along with the comparison of various treatment options, we opted for a literature review as our research approach.

METHODS

A review of the literature was performed using PubMed Database and search terms included "posterior epistaxis", "treatment", "management", "guidelines", "algorithm" "nasal packing", "posterior packing", "surgery", "SPA ligation", "embolization", "risk factors" or a combination of the above.

RESULTS

Initial patients' assessment invariably results in most cases in posterior packing. There seems to be a superiority in recent literature of early surgery over nasal packing as a definitive treatment. Embolization is usually used after surgery failure, except for specific occasions.

CONCLUSION

Despite the vast heterogeneity of information, there seems to be a need for re-evaluation of the well-established treatment plans according to more recent studies.

Incidence of Neoplasm in Patients Referred for Epistaxis

Objectives: The primary objective was to identify the incidence of neoplastic disease in patients referred for epistaxis. Secondary objectives included identification of any mass lesion, and the need for further workup with imaging and/or biopsy as well as risk factors associated with identification of a mass lesion. Study Design: Retrospective cohort study. Methods: Medical records of adult patients who presented to Tufts Medical Center over an 11 year period (2010-2021) with a chief complaint of epistaxis were reviewed. The primary outcome was identification of a nasal or nasopharyngeal mass. Patient characteristics including age, sex, race, smoking status, anticoagulation, comorbidities (hypertension, allergic rhinitis, vasculitis), and treatment of epistaxis (used as surrogate for severity of epistaxis) were also examined. Results: A total of 1164 patients met inclusion and exclusion criteria. Thirty-six nasal masses were found among patients presenting with epistaxis (3.09%, P < .001), comprised primarily of benign etiology (2.66%) including nasal polyposis and thornwaldt cyst. Asian race correlated with finding of mass lesion (75%, P = .007). Five malignancies were found (0.43%) including nasopharyngeal carcinoma (2 patients), extranodal natural killer T-cell lymphoma (2 patients), and nasal adenocarcinoma (1 patient). Conclusions: Epistaxis is a common cause for referral to otolaryngology. Although the incidence of neoplasm in our patient population was low, nasal mass lesions warranting further workup were identified in 36 patients. Findings of neoplasm were more common in patients of Asian ethnicity, which may reflect the increased prevalence of nasopharyngeal carcinoma in this population. Otolaryngologic evaluation and nasal endoscopy should be considered in all cases of epistaxis.

Comparative effectiveness of various noninvasive local treatments in patients with epistaxis: A systematic review and network meta-analysis

BACKGROUND

The best initial strategy for managing epistaxis is unclear. We performed a systematic review and network meta-analysis (NMA) to compare the effectiveness of various noninvasive treatments for patients with epistaxis.

METHODS

We searched PubMed, Embase, and the Cochrane Library from inception to September 2022 without language restrictions. Randomized controlled trials (RCTs) assessing immediate hemostasis, 2-day and 7-day rebleeding outcomes, as well as the use of noninvasive interventions for the treatment of epistaxis were selected. Frequentist NMA was performed.

RESULTS

The systematic review included 20 RCTs (2994 participants) involving 12 different interventions. The NMA demonstrated that topical treatment with tranexamic acid (TXA) significantly reduced the odds of 2-day rebleeding compared with the control conservative treatment (odds ratio [OR] 0.36, 95% confidence interval [CI] 0.21-0.61) and traditional anterior nasal packing (OR 0.45, 95% CI 0.26-0.76). The sensitivity analysis yielded robust results, and the overall evidence was high. Topical TXA significantly reduced the odds of 7-day rebleeding compared with traditional nasal packing (OR 0.33, 95% CI 0.15-0.70), with moderate evidence owing to the heterogeneous results. Despite the significant effects of topical TXA on achieving immediate hemostasis and Rapid Rhino nasal packing on preventing 2-day rebleeding compared to the control and traditional nasal packing, the evidence is low to very low due to heterogeneity, inconsistency, and within-study bias.

CONCLUSIONS

In the treatment of epistaxis, topical TXA may be superior to conservative treatment or traditional nasal packing, particularly in preventing 2-day rebleeding.

Complications and Outcomes of Endovascular Embolization for Intractable Epistaxis: A Systematic Review and Meta-analysis

OBJECTIVES

Endovascular embolization has emerged as an effective treatment for intractable epistaxis. This systematic review and meta-analysis aimed to calculate the rates of success, rebleeds, and complications and to identify the etiologies and complications of patients who undergo endovascular embolization.

METHODS

This systematic review and meta-analysis was conducted per the guidelines set forth by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA). Articles were extracted from Scopus, PubMed, Web of Science, and Cochrane Central and were filtered by a systematic review process using Rayyan software. A random-effects model was used to quantify the rates success, rebleeds, and complications.

RESULTS

Forty-two studies were included, totaling 1660 patients. The pooled success rate was 89% (95% confidence interval [CI] 86%-92%) and the pooled rebleed rate was 19% (95% CI 16%-22%). The pooled minor complication rate was 18% (95% CI 11%-27%). The most common major complication was soft tissue necrosis followed by stroke. The most common minor complication was facial pain. No minor complications were reported to be permanent. Of the patients who failed initial embolization, 42% underwent repeat embolization and 34% underwent surgical arterial ligation.

CONCLUSIONS

Endovascular embolization is an effective treatment for intractable epistaxis. The decision to perform embolization should be carefully weighed given the rare but significant major complications.

The Arterial Pattern of the Upper Nasal Septum (S-Point) and Potential Role in Severe Epistaxis

OBJECTIVES

The previously described S-point, corresponds to the medial projection of the middle turbinate axilla in the superior nasal septum and has been identified as a common source of severe epistaxis. The objective is to define the anatomical patterns of vascularization of the S-point area that could explain its clinical relevance.

METHODS

Thirty-three nasal septums of latex-injected formalin-embalmed and fresh human cadaveric heads were dissected to analyze the arterial arrangement of the S-point area. Measurements and patterns of vascularization were described.

RESULTS

The S-point area, was consistently surrounded by a single or multiple arterial anastomotic arches consistently formed superiorly by the anterior ethmoidal and posterior ethmoidal artery branches, and inferiorly by the posterior septal artery. The caliber of the arterial arches was typically larger than the caliber of the arterial branches supplying them. A single arch was present in 36.3% of septums, and multiple arches in 63.6%. The mean distance from the S-point to the anterior limit of the arch was 9 mm, to the posterior arch when the present was 3 mm, to the superior limit 6 mm, to the inferior limit 6 mm, and to the nasal roof was 10 mm.

CONCLUSION

This study demonstrates the dense arterial configuration of the S point area, which is characterized by a single or multiple vascular arches of greater caliber than the branches of origin. This finding could explain why the S-point area is a frequent source of epistaxis, and guide its surgical cauterization when an obvious vascular ectasia is not visualized.

Knowledge, Attitude, and Practice of First Aid for Epistaxis Among the General Population in the Jazan Region of Saudi Arabia

Background Epistaxis, or nosebleeds, is a widespread medical condition that can be effectively managed with appropriate first aid. Understanding the general public's knowledge and practices about this is crucial. Objectives This study sought to evaluate the awareness and practice regarding first aid for epistaxis within the general population of the Jazan region in Saudi Arabia. Methods A cross-sectional survey was administered from April through June 2023, using a questionnaire that covered sociodemographic factors, knowledge of epistaxis, first aid practices for epistaxis, and any previous training received. Statistical analysis was performed using SPSS (IBM Corp., Armonk, NY), with chi-square tests to evaluate the variables' associations. Results The questionnaire was completed by 622 participants, predominantly females, Saudis, and individuals from the age group of 18 to 25 years. It was found that 60% of the participants had experienced epistaxis, but only 52% had received prior first aid training. Although the majority (91.8%) accurately defined epistaxis, a mere 40.8% correctly identified all the steps for first aid management of epistaxis. There was a notable insufficiency in understanding the causes, risk factors, and appropriate first aid steps. Participants' knowledge was evenly split, with approximately half exhibiting low knowledge (49.70%) and the remainder showing high knowledge (50.30%). Certain sociodemographic factors such as older age (p=0.028), Saudi nationality (p=0.045), and higher education (p=0.001) were linked with more experiences of epistaxis. Conversely, younger age (p=0.002), female gender (p=0.036), single status (p=0.001), prior experience with epistaxis (p=0.001), and higher overall knowledge (p=0.001) were associated with a higher likelihood of having received first aid training. Conclusions The study reveals significant gaps in the knowledge and practices of first aid for epistaxis among the general population in the Jazan region. Public awareness campaigns and educational programs are urgently needed, particularly for specific groups. Enhancing first aid knowledge could help alleviate the impacts of epistaxis. Further research is required to develop effective educational interventions.

Risk Factors for Severe Clinical Course in Epistaxis Patients

Purpose: Epistaxis is a common medical emergency that may require admission to the emergency department (ED) and treatment by an otolaryngologist. Currently, there are no widely accepted indications for hospitalization, and the decision is based on personal experience. Methods: A retrospective study of 1171 medical records of patients with epistaxis treated at our tertiary medical center ED from 2013 to 2018 with no age limit. The presence of recurrent epistaxis, a posterior source of bleeding, the need for hospitalization, the need for blood transfusion, or surgical intervention defined severe clinical course. Results: The 1171 admissions included 230 recurrent admissions for a total of 941 patients (60% males) who were treated by an otolaryngologist. The average age was 57.6 in the adult population (>15) and 6.6 in the pediatric population (≤15). Of all patients, 39% had hypertension; 39% took antiplatelet/anticoagulation therapy; 63% came during winter-a significant risk factor; 34 (2.9%) had reduced hemoglobin levels of >1gr%, but only 7 received a blood transfusion; 131 (11%) were hospitalized, and 21 (1.8%) required surgical control of the bleeding. Age (OR 1.02; CI 1.01-1.023), male sex (OR 2.07; CI 1.59-2.69), hypertension (OR 1.76; CI 1.27-2.45), and antiplatelet/anticoagulation therapy (OR 2.53; CI 1.93-3.33, OR 1.65; CI 1.11-2.44, respectively), were significantly correlated with severe clinical course. Conclusion: Epistaxis is significantly more common and severe in older male patients with hypertension or antiplatelet/anticoagulation therapy. However, few need a blood transfusion or surgical intervention. In borderline cases with no definitive indication for hospitalization, we suggest adopting these factors as indications for hospitalization due to their marked influence on the clinical course. Routine coagulation tests are indicated in patients treated with warfarin or combined antiplatelet + anticoagulation therapy.

Where should epistaxis education be focused? A comparative study between the public and healthcare workers on knowledge of first aid management methods of epistaxis

BACKGROUND

Epistaxis can be life-threatening. Simple first aid management can stem bleeding. This study compared knowledge of first aid management methods of epistaxis between the general public and healthcare workers.

METHOD

A cross-sectional study of 100 healthcare workers and 103 adult members of the public was conducted at a large London teaching hospital. Respondents completed a survey assessing knowledge on nasal pinching site, head tilt and appropriate adjunct treatment use for first aid management of epistaxis.

RESULTS

Twenty-four per cent and 68 per cent of healthcare workers compared with 25.2 per cent and 37.9 per cent of the public answered correctly on nasal pinching position and head tilt position, respectively, with a statistical difference for head tilt position. Two per cent, 2 per cent and 24 per cent of healthcare workers mentioned ice use on the nose, ice use in the mouth or ice use but not site, respectively, compared with 0 per cent, 0 per cent and 4.9 per cent of the public, with a statistical difference for ice without site.

CONCLUSION

Healthcare workers and the public lack knowledge on first aid management of epistaxis. Improved education on first aid management is required, targeting healthcare workers and the public.

Nasal Packing in Septal Surgery: A Narrative Review

Recently, alternatives to intranasal packing following septoplasty and rhinoseptoplasty have been widely used and promoted. Here, we aimed to systemically review and compare the different types of nasal packing used in these two surgeries. To assess patient comfort and surgical outcomes, we conducted a comprehensive search of multiple databases such as PubMed, MEDLINE, Web of Science, and Google Scholar to identify and evaluate relevant articles. A detailed and extensive search was performed with the help of the keywords "nasal packing," "septoplasty," "rhinoseptoplasty," "nasal splints," and "intranasal packing." Overall, our review findings indicate that alternative methods (e.g., trans-septal suturing and insertion of intranasal splints) are better options than intranasal packing.

Analysis of Care and Outcomes for Epistaxis Weekend Admissions

OBJECTIVES

To study differences in care of patients admitted for epistaxis during the weekend compared to the weekday.

STUDY DESIGN

Retrospective database review.

SETTING

2003 to 2014 National Inpatient Sample.

METHODS

Patients admitted for a primary diagnosis of epistaxis were extracted from the National Inpatient Sample from 2003 to 2014. Univariate and multivariate analyses were applied to assess differences in patient demographics, clinical characteristics, treatment, and outcomes between weekend and weekday admissions.

RESULTS

A total of 39,329 cases were included in our study cohort, with 28,458 weekday admissions and 10,892 weekend admissions. There was no significant difference in patient race, gender, insurance status, hospital ownership status, or location between weekend and weekday admissions (p > .05). Most weekend admissions were emergent (82.2%) and were treated with packing (51.8%). Upon performing logistic regression, the likelihood of emergent admission (odds ratio [OR] 1.41, 95% confidence interval [CI] 1.32-1.51, p < .001) and prolonged length of stay (OR 1.11, 95% CI 1.05-1.17, p < .001) was higher for weekend admissions versus weekday admissions. Moreover, odds of packing for epistaxis were significantly higher (OR 1.14, 95% CI 1.09-1.19, p < .001) on the weekend, while odds of ligation (OR 0.88, 95% CI 0.80-0.97, p = .013) and endovascular arterial embolization (OR 0.74, 95% CI 0.65-0.84, p < .001) were lower. There were no significant differences in in-hospital mortality, patient discharge disposition, and total hospital charges (p > .05).

CONCLUSION

Patients primarily admitted for epistaxis over the weekend were more likely to be emergent, experienced prolonged length of stay, and be treated nonoperatively with packing, than weekday admissions. No significant differences in patient insurance or hospital ownership were identified.

The Level of School Teachers' Knowledge About First-Aid Management and Control of Epistaxis in Qassim Region, Saudi Arabia

BACKGROUND

 Epistaxis is an acute episode of nasal bleeding commonly caused in children by traumatic injuries in a school setting. It is one of the common ear, nose, and throat emergencies, which should be managed with first-aid measures. To the best of our knowledge, no studies have been conducted among school teachers in the Qassim region of Saudi Arabia regarding this information. This study thus aimed to assess levels of knowledge about first-aid management and control of epistaxis among school teachers in the Qassim region, Saudi Arabia.

MATERIALS AND METHODS

 A cross-sectional study using a validated online questionnaire was distributed via social media platforms. Information was collected regarding sociodemographic characteristics, and eight items assessed participants' knowledge about epistaxis and its management. Univariate, bivariate, and multivariable analyses were conducted to assess the factors associated with good levels of knowledge.

RESULTS

 The study had a total of 1,152 participants, of which 69.7% were female. The mean of knowledge was 3.29 (SD=1.39, range: 0-7). Only 19.4% of participants had a good level of knowledge. In multivariate analysis, females and those who had received information on first aid to stop nose-bleeds were significantly associated with good knowledge levels (adjusted odds ratio {AOR}: 1.72, 95% CI: 1.18-2.51, p=0.005; and AOR: 3.38, 95% CI: 2.47-4.64, p<0.001, respectively).

CONCLUSION

 Less than one-quarter of participants had good knowledge levels. Health education sessions for teachers are highly recommended and should specifically target male teachers.

[Epidemiology and modern methods of treatment of non-traumatic nosebleeds]

Data on the detection incidence of nosebleeds (NBs) of non-traumatic origin in the population show considerable variability in statistical indicators, and NBs treatment and consequences depend on the localization of hemorrhage source, the volume of blood loss, patient's general condition, the presence and nature of comorbid pathology and a number of other factors. There are some differences in the choice of NBs treatment options, evaluation of their clinical and economic efficiency, which indicates the need to analyze and systematize the results of such studies.

OBJECTIVE

To analyze data on prevalence and current treatment approaches of non-traumatic nosebleeds.

MATERIAL AND METHODS

The search for publications (articles and related abstracts) on the subject of the study, presented in the PubMed database, has been conducted. The choice of material was made according to the following key words: non-traumatic nosebleeds, causes, incidence, methods of stopping nosebleeds.

RESULTS

The literature data show a significant prevalence of NBs in the population, their potential hazard to the life of patient and the importance of clinical and demographic characteristics of persons for determining treatment tactics in each case. In practical terms, primary and secondary NBs should be distinguished. In case of primary NB, the use of coagulation and nasal packing is recommended after determining the place of bleeding. In secondary NB it is necessary to establish its cause in order to assess risk factors and apply appropriate topical or systemic drug therapy. The so-called difficult (difficult-to-treat) NBs deserve special attention. As a rule, these cases involve bleeding from the posterior parts of nose. The analysis of publications shows a high (90%) efficacy of surgical interventions, used as first-line treatment. Effectiveness of embolization in such cases was 75% and of anterior/posterior nasal packing was 62%.

CONCLUSION

The literature data show a significant prevalence of nosebleeds in the population and their potential hazard to the life of patient. The existing differences in the assessments of treatment options for this pathology, their clinical and economic efficiency are the basis for further research, in particular, to clarify the causes of nosebleeds' occurrence and recurrence, the impact of treatment methods on quality of patients' life.

Epistaxis duration predicts bleeding in immune thrombocytopenia: a cohort study

OBJECTIVE

To test for an association between duration of epistaxis and clinically relevant bleeding in the following 12 months in children with immune thrombocytopenia (ITP).

DESIGN

Prospective cohort study.

SETTING

The national UK Paediatric ITP registry, a multicentre prospective clinical registry of new cases of ITP between 2006 and February 2020.

PATIENTS

All children aged between 2 months and 16 years in participating UK centres.

EXPOSURE

Epistaxis at presentation defined as none, <10 min, 10-30 min and >30 min.

MAIN OUTCOME MEASURES

Incident severe bleeds, combined moderate and severe bleeds and drop in haemoglobin (Hb) by ≥20 g/L.

RESULTS

The sample included 1793 patients, of which 334 had epistaxis <10 min, 88 lasting 10-30 min and 97 >30 min. In the 12 months following presentation, 19 had a severe bleed, 140 had a moderate bleed and 54 had a drop in Hb ≥2 g/dL. Epistaxis >30 min duration was associated with increased odds of severe bleeds (OR 1.43-15.67), moderate or severe bleeding (OR 1.33-4.2) and drop in Hb (OR 1.23-6.91). Shorter duration epistaxis was not associated with increased odds of any outcome. A trend for increased odds with longer duration epistaxis was significant for all outcomes.

CONCLUSIONS

The longer the duration of epistaxis at presentation with ITP, the higher the risk of a clinically significant bleeding event in the 12 months following. This should inform clinical severity ratings and treatment decisions.

Racial Disparities in Charges, Length of Stay, and Complications Following Adult Inpatient Epistaxis Treatment

BACKGROUND

Although recent studies have identified an association between race and adverse outcomes in head and neck surgeries, there are limited data examining the impact of racial disparities on adult inpatient outcomes following epistaxis management procedures.

OBJECTIVE

To analyze the association between race and adverse outcomes in hospitalized patients undergoing epistaxis treatment.

METHODS

This retrospective cohort analysis utilized the 2003 to 2014 National Inpatient Sample. International Classification of Diseases, Ninth Revision codes were used to identify cases with a primary diagnosis of epistaxis that underwent a procedure for epistaxis control. Cases with missing data were excluded. Higher total charges and prolonged length of stay (LOS) were indicated by values greater than the 75th percentile. Demographics, hospital characteristics, Elixhauser comorbidity score, and complications were compared among race cohorts using univariate chi-square analysis and one-way analysis of variance (ANOVA). The independent effect of race on adverse outcomes was analyzed using multivariate binary logistic regression while adjusting for the aforementioned variables.

RESULTS

Of the 83 356 cases of epistaxis included, 80.3% were White, 12.5% Black, and 7.2% Hispanic. Black patients had increased odds of urinary/renal complications (odds ratio [OR] 2.148, 95% confidence interval [CI] 1.797-2.569, P < .001) compared to White patients. Additionally, Black patients experienced higher odds of prolonged LOS (OR 1.227, 95% CI 1.101-1.367, P < .001) and higher total charges (OR 1.257, 95% CI 1.109-1.426, P < .001) compared to White patients. Similarly, Hispanic patients were more likely to experience urinary/renal complications (OR 1.605, 95% CI 1.244-2.071, P < .001), higher total charges (OR 1.519, 95% CI 1.302-1.772, P < .001), and prolonged LOS (OR 1.157, 95% CI 1.007-1.331, P = .040) compared to White patients.

CONCLUSION

Race is an important factor associated with an increased incidence of complications in hospitalized patients treated for epistaxis.

Risk Factors and Management for Epistaxis in a Hospitalized Adult Sample

INTRODUCTION

Epistaxis is a common otolaryngologic problem that affects most of the general population. Common risk factors for epistaxis include nasal irritants, nasal/facial oxygen use, certain systemic conditions (e.g., hypertension and coagulopathies) and medication use (e.g., anticoagulants and intranasal medications). This study examined risk factors for and management of epistaxis in patients admitted for other medical conditions who developed an episode of epistaxis during their hospital admission.

METHODS

Patients were included in the study if they were older than 18, admitted for medical illnesses other than epistaxis and developed an episode of epistaxis during their admission during calendar year 2020 at the authors' institution's hospitals. Electronic health record data regarding sociodemographic characteristics, common risk factors (e.g. oxygen use, anticoagulant use, history of hypertension) and treatment for epistaxis (e.g. holding anticoagulation therapy, administration of oxymetazoline, nasal cautery, nasal packing) were extracted from each chart. Patients were split into otolaryngologic treatment versus no treatment groups and risk factors were compared between sample subgroups.

RESULTS

A total of 143 sample patients were included, with most common reason for admission being cardiovascular related, 48 (33.6%). Most patients, 104 (72.7%), did not have a previous diagnosis of epistaxis, were positive for anticoagulant use, 106 (74.1%) and were positive for hypertension, 95 (66.4%). Oxygen use showed a significantly decreased risk for intervention (OR 0.45, 95% CI: 0.23-0.894; p = 0.028). Most patients required changes in medical management (e.g., holding anticoagulation or starting nasal saline sprays/emollients).

CONCLUSION

These results demonstrate the common risk factors for epistaxis in patients admitted for other clinical diseases. Identifying at-risk patients for epistaxis at hospital admission can help to initiate measures to prevent epistaxis episodes. Future studies are needed to study epistaxis risk factors and identify effective preventative measures for epistaxis among hospital populations.

Clinical analysis of delayed epistaxis following endoscopic sinus surgery

OBJECTIVE

To investigate the clinical characteristics and treatment methods associated with delayed epistaxis following endoscopic sinus surgery.

METHODS

The clinical data of 46 patients with delayed epistaxis following endoscopic sinus surgery were retrospectively analyzed. To explore the clinical features, pathogenesis, and treatment plan for delayed epistaxis, the postoperative bleeding time, bleeding inducements, systemic complications, surgical approach, the hemorrhage locations and responsible vessels, and treatment methods were analyzed.

RESULTS

The average bleeding time was 16.34 ± 9.05 days after the operation, and 76.6% of the cases occurred 6-20 days after the operation. Sphenopalatal artery hemorrhage accounted for 69.6% (32/46), the most common of which was a posterior nasal septal artery hemorrhage (17/32). A total of 45 patients received endoscopic low-temperature plasma hemostasis following ineffective nasal packing, and no rebleeding in the ipsilateral nasal cavity was observed during the postoperative follow-up for 3 to 6 months.

CONCLUSIONS

The peak of hemorrhaging in delayed epistaxis following endoscopic sinus surgery occurred at 6-20 days post-operatively. Bleeding of the posterior nasal septal artery from the sphenopalatine artery was the most common. Surgical methods were closely related to delayed postoperative hemorrhage. Treatment with low temperature plasma hemostasis under nasal endoscope was found to be effective.

Risk of SARS-CoV-2 contagion in otolaryngology specialists

COVID-19 has rapidly spread in the past two years with a profound impact on otolaryngological activities, which has undergone radical transformation to guarantee diagnostic and therapeutic procedures mainly in oncology and urgent patients, while ensuring protection for healthcare personnel and patients. During the initial phases of the pandemic, scheduled visits and elective surgeries were postponed leading to a delay in the diagnosis and treatment of several diseases, including head and neck cancer, with a shift toward more advanced cancer stages and more aggressive treatments. Aerosol and droplets are the main routes of transmission of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), thus leading to a high risk of contagion during otolaryngology visits and surgery. Therefore, the correct use of personal protective equipment (PPE) and attention to procedure-specific risks and measures to avoid contagion are of utmost importance for healthcare professionals, and especially for those dealing with otolaryngology diseases. This narrative review highlights that otolaryngological activity implies a high risk of contagion during outpatient visit, surgery, or urgent conditions. The correct use of PPE, evaluation of procedure-specific risks and reduction of non-urgent procedures are considered the main strategies to limit contagion.

Refractory epistaxis and Stamm's S-point

PURPOSE OF REVIEW

Ethmoidal arteries are gaining increasing importance as the main source of severe refractory epistaxis. In this direction, Stamm's S-point, a specific bleeding point in the upper nasal septum, around the projection of the axilla of middle turbinate, posterior to the septal body, was recently described. The aim of this review was to present recent data on S-point and its role in severe refractory epistaxis.

RECENT FINDINGS

Due to the hidden location posterior to the septal body, S-point is not easily identified by anterior rhinoscopy. When systematic endoscopic assessment was performed in severe epistaxis to search for the precise bleeding point, S-point was clearly the most identified (23.7-28.3%). Electrocauterization of bleeding point had high success rates (91.5-100%) and decreased the risk of recurrence bleeding.

SUMMARY

Stamm's S-point plays an important role in severe refractory epistaxis, due to its frequency and stability. However, this specific bleeding point could not be easily identified, so systematic endoscopic assessment should be performed. Recent data has shifted the paradigm of the main source of severe epistaxis from the sphenopalatine artery to ethmoidal arteries and presented high success rates for electrocauterization of bleeding points as single treatment of severe epistaxis.

Case report: A case of acquired von Willebrand syndrome as onset clinical presentation of systemic lupus erythematosus manifested as epistaxis and pulmonary hemorrhage

BACKGROUND

Acquired von Willebrand syndrome (AVWS) is a less common bleeding disorder, primarily manifested as mild to moderate mucocutaneous bleeding and laboratory tests are similar to hereditary von Willebrand disease (VWD). AVWS is secondary to other diseases, and systemic lupus erythematosus (SLE) is a relatively rare cause.

CASE PRESENTATION

We report a case of AVWS as onset clinical presentation of SLE manifested as epistaxis and pulmonary hemorrhage. A 13-year-old male child presented to the hospital with a six-month history of recurrent epistaxis and a one-month history of anemia. Routine blood tests demonstrated severe normocytic anemia and normal platelet count. Von Willebrand test revealed a significantly lower level. High-resolution chest computed tomography (CT) showed patchy ground glass opacities consistent with hemorrhagic changes. After ruling out the family history, the patient was diagnosed with AVWS. Additional tests confirmed positive antinuclear and anti-Sm antibodies. The underlying SLE was diagnosed and treated with methylprednisolone with disease recovery.

CONCLUSION

We recommend screening for bleeding disorders in patients with recurrent epistaxis. AVWS should be considered when laboratory findings suggest hereditary von Willebrand disease without a personal or familial history of bleeding. In addition, the underlying disease should be explored.

Nasal Packing in the Emergency Department: A Practical Review for Emergency Providers

We performed a narrative review of epistaxis management in the emergency department. First, we examined the pathophysiology, the current types of treatment that are available to emergency clinicians. When nasal packing is indicated, we examined the efficacy of nasal packing in addition to other topical treatment such as tranexamic acid and the evidence of prophylactic antibiotics. We detailed current studies involving tranexamic acid and prophylactic antibiotics for nasal packing. Finally, we introduced an epistaxis clinical care pathway, based on current evidence, to aid emergency clinicians with their clinical decision-making processes.

Direct oral anticoagulants versus vitamin K antagonists in epistaxis patients: A systematic review and meta-analysis

OBJECTIVE

Epistaxis is the most common otolaryngological emergency and up to one third of patients in treated on an inpatient basis take oral anticoagulants (OAC). Direct oral anticoagulants (DOAC), an OAC subgroup, have been on the market since 2010 and are being increasingly prescribed due to the cardiological and haematological guidelines that favour them over vitamin K antagonists (VKA), the older of the OAC subgroups. The present study aims to investigate which subgroup of epistaxis patients taking OACs has a more favourable outcome.

DESIGN/SETTING

A systematic review and meta-analysis were performed according to the PRISMA 2020 statement using the PubMed and Cochrane Library databases. Continuous data were analysed and standardised mean difference (SMD) was calculated according to Hedges' g. Dichotomous data were analysed, and the Mantel-Haenszel method was applied to establish the odds ratio (OR). Heterogeneity was assessed according to the I²  statistics.

MAIN OUTCOME/RESULTS

A total of eight reports covering 1390 patients were included in the final synthesis. The pooled analysis demonstrated significantly shorter hospital stays in the DOAC group (SMD = -0.22, 95% CI-0.42 to -0.02, p = .03) and a significantly higher rate of posterior bleeding in the VKA group (OR = .39, 95% CI 0.23 to 0.68, p = .001). No statistically significant differences with regard to recurrence rates, admission rates, the need for transfusion or surgical intervention (p = .57, .12, .57 and .38 respectively) were found.

CONCLUSION

According to this meta-analysis, epistaxis patients taking DOACs have a more favourable outcome than patients taking VKAs.

The Procoagulant Activity of Emoxilane®: A New Appealing Therapeutic Use in Epistaxis of the Combination of Sodium Hyaluronate, Silver Salt, α-tocopherol and D-panthenol

Epistaxis is one of the most frequent hemorrhages resulting from local or systemic factors. Its management without hospitalization has prompted an interest in locally applied hemostatic agents. Generally, the therapy approaches involve sprays or creams acting as a physical barrier, even used as tampons or gauze. In this study, we have investigated the activity of Emoxilane^®, a combination of sodium hyaluronate, silver salt, α-tocopherol acetate and D-panthenol, which is known to be able to separately act in a different biological manner. Our in vitro results, obtained on endothelial and nasal epithelial cells, have shown that the association of these molecules presented a notable antioxidant activity mainly due to the α-tocopherol and D-panthenol and a significant antimicrobial role thanks to the silver compound. Moreover, remarkable hemostatic activity was found by evaluating plasmin inhibition attributable to the sodium hyaluronate. Interestingly, on human plasma, we have confirmed that Emoxilane^® strongly induced the increase of thrombin levels. These data suggest that the use of this association could represent an appealing pharmacological approach to actively induce hemostasis during epistaxis. Our future perspective will aim to the creation of a formulation for an easy topical application in the nose which is able to contrast the bleeding.

Management of epistaxis: a guide for junior doctors

Epistaxis is commonly seen as an acute presentation to the emergency department. The level of severity can range from a minor ooze to a life-threatening bleed. The initial management is often the responsibility of junior doctors working in otolaryngology or the emergency department, so they must be familiar with the initial steps in treating this often distressing condition. The COVID-19 pandemic has complicated matters further as much of the management takes place in the upper airway. This article outlines the key considerations in the management of epistaxis, especially during the COVID-19 pandemic.

The power of a checklist: Decrease in emergency department epistaxis transfers after clinical care pathway implementation

BACKGROUND

Annually, epistaxis costs US hospitals over $100 million dollars. Many patients visit emergency departments (ED) with variable treatment, thus providing opportunity for improvement.

OBJECTIVE

To implement an epistaxis clinical care pathway (CCP) in the ED, and analyze its effects on treatment and ED transfers.

METHODS

An interdisciplinary team developed the CCP to be implemented at a tertiary hospital system with 11 satellite EDs. The analysis included matched eight-month periods prior to pathway implementation and after pathway implementation. Subjects included patients with ICD-10 code diagnosis of epistaxis. Patients under 18 years old, recent surgery or trauma, or bleeding disorders were excluded. There were 309 patients from the pre-implementation cohort, 53 of which were transferred and 37 met inclusion criteria; 322 from the post-implementation cohort, 37 of which were transferred, and 15 met inclusion criteria. Outcome measures included epistaxis intervention by ED providers and otolaryngologists before and after pathway implementation.

RESULTS

CCP implementation resulted in a 61% reduction in patient transfers (p < 0.001). ED providers showed a 51% increase in documentation of anterior rhinoscopy with proper equipment, 34% increased use of topical vasoconstrictors, 40% increased use of absorbable packing, 7% decrease in use of unilateral non-absorbable packing, and 17% decrease in use of bilateral non-absorbable packing.

CONCLUSIONS

Prior to CCP implementation, ED treatment of epistaxis varied significantly. CCP resulted in standardized treatment and significant reduction in transfers. A CCP checklist is an effective way to standardize care and prevent unnecessary hospital transfers.

Recurrent epistaxis in children

QUESTION

A child came to my clinic complaining of recurrent epistaxis with several episodes occurring every year since he was a toddler. The nosebleeds affect both nostrils, often lasting for an extended period of time and occurring in no apparent seasonal pattern. What interventions are safe and effective for recurrent epistaxis in children, and which patients warrant hematologic testing?

ANSWER

Epistaxis affects more than half of children by the time they are 10 years old, with 9% of children reported to have recurrent episodes. Most cases are of benign origin and will not require further workup. For those seeking intervention, nasal mucosal hydration, such as emollient application, or humidification resolves up to 65% of cases, and many novel interventions have shown promise in their respective initial studies. Standardized bleeding questionnaires have demonstrated usefulness in decision making for further coagulation studies, taking into account historical features including frequency, duration, bleeding site, seasonal correlation, and severity.

Assess and evaluate knowledge, attitude and practice of first aid management of epistaxis among general population in Aseer region

Introduction

Epistaxis or nose bleeds is one the most common reported emergencies in the ear, nose and department. Causes of epistaxis varies from being trivial such as nose picking or dry air or trauma to concerning such as infections or elevated blood pressure to life threatening condition such as malignancies.

Methods

The purposely constructed questionnaire was used for this research. The questionnaire was constructed by the panel of experts, language, psychological, doctors and subject specialist was there in the team. Internal consistencies of the questionnaire was measure through cronbach alpha.

Results

Cronbach alpha = 0.84. Mean ± S.D of age of the respondents were 27.8 ± 9.8. 71.6% were females, 91.5% were belongs to Aseer region, 86.6% were living in village, 77.0% have intermediate level of education, 59.2% were single, 41.6% having health care profession. 51.1% having income less than 5000SAR.

Conclusion

Most of them rely on internet and social media to gain knowledge regarding home management of epistaxis. This has limitations as they do not get a hands-on experience. Therefore, we recommend that first aid camps and workshops in management of epistaxis should be organized in order to properly educate the general population regarding its home management.

Clinical Decision Support Systems in Otolaryngology-Head and Neck Surgery: A State of the Art Review

OBJECTIVE

To offer practical, evidence-informed knowledge on clinical decision support systems (CDSSs) and their utility in improving care and reducing costs in otolaryngology-head and neck surgery. This primer on CDSSs introduces clinicians to both the capabilities and the limitations of this technology, reviews the literature on current state, and seeks to spur further progress in this area.

DATA SOURCES

PubMed/MEDLINE, Embase, and Web of Science.

REVIEW METHODS

Scoping review of CDSS literature applicable to otolaryngology clinical practice. Investigators identified articles that incorporated knowledge-based computerized CDSSs to aid clinicians in decision making and workflow. Data extraction included level of evidence, Osheroff classification of CDSS intervention type, otolaryngology subspecialty or domain, and impact on provider performance or patient outcomes.

CONCLUSIONS

Of 3191 studies retrieved, 11 articles met formal inclusion criteria. CDSS interventions included guideline or protocols support (n = 8), forms and templates (n = 5), data presentation aids (n = 2), and reactive alerts, reference information, or order sets (all n = 1); 4 studies had multiple interventions. CDSS studies demonstrated effectiveness across diverse domains, including antibiotic stewardship, cancer survivorship, guideline adherence, data capture, cost reduction, and workflow. Implementing CDSSs often involved collaboration with health information technologists.

IMPLICATIONS FOR PRACTICE

While the published literature on CDSSs in otolaryngology is finite, CDSS interventions are proliferating in clinical practice, with roles in preventing medical errors, streamlining workflows, and improving adherence to best practices for head and neck disorders. Clinicians may collaborate with information technologists and health systems scientists to develop, implement, and investigate the impact of CDSSs in otolaryngology.

Otolaryngology Consult Protocols in the Setting of COVID-19: The University of Pittsburgh Approach

Objective:

To analyze trends in otolaryngology consultations and provide algorithms to guide management during the COVID-19 pandemic.

Methods:

A retrospective cohort study at a single institution tertiary care hospital. A total of 95 otolaryngology consultations were performed from March 1, 2020 to April 26, 2020 (COVID-era) and 363 were performed from September 1, 2019 to February 29, 2020 (pre-COVID-era) at the UPMC Oakland campus. Data collected included patient demographics, COVID-19 status, reason for consult, location of consult, type of consult, procedures performed, need for surgical intervention, length of hospital stay and recommended follow up.

Results:

Patient populations in the pre-COVID-era and COVID-era were similar in terms of their distribution of demographics and chief complaints. Craniofacial trauma was the most common reason for consultation in both periods, followed by vocal fold and airway-related consults. We saw a 21.5% decrease in the rate of consults seen per month during the COVID-era compared to the 6 months prior. Review of trends in the consult workflow allowed for development of several algorithms to safely approach otolaryngology consults during the COVID-19 pandemic.

Conclusions:

Otolaryngology consultations provide valuable services to inpatients and patients in the emergency department ranging from evaluation of routine symptoms to critical airways. Systematic otolaryngology consult service modifications are required in order to reduce risk of exposure to healthcare providers while providing comprehensive patient care.

An image-guided (CT) assessment of a new asymmetric balloon for the treatment of epistaxis

PURPOSE

The main objective was to perform an image-guided (CT) assessment of the efficacy of the CAVI-T™ balloon to compress the sphenopalatine artery (SPA) on cadaver heads, for the management of epistaxis. The secondary objectives were to analyse the deployment and stability of this balloon according to the volume injected into the nasal cavity, to optimise its use.

METHODS

A descriptive anatomical study was performed. The catheterization of the SPA was performed on four fresh-frozen heads with a SPA approach through the maxillary sinus, leaving the nasal cavity unscathed. Computed Tomography images were acquired without and with the balloon, inflated by injections of progressive volumes of diluted iodine, for optimal contrast with the surrounding tissues. We evaluated the positioning of the balloon according to two predetermined markers on the device.

RESULTS

Out of 68 image-guided acquisitions, the CAVI-T™ balloon compressed the SPA in 88% of cases. The other nasal cavity structures were compressed in 86% to 100% of the cases, depending on the positioning of the CAVI-T™ balloon, therefore allowing a complete obstruction of the nasal cavity. The device remained stable upon inflation and did not obstruct the nasopharynx.

CONCLUSION

The CAVI-T™ balloon provided effective compression of the SPA and the different structures of the nasal cavity.

Epistaxis first-aid management: a needs assessment among healthcare providers

Purpose

To perform a needs assessment of epistaxis first-aid measures practiced by family physicians and Emergency Department (ED) staff in London, Ontario, Canada.

Methods

Paper-based multiple-choice questionnaires were distributed to participants. Participant recruitment was conducted in two parts: 1) 28 Emergency Medicine (EM) attending physicians, 21 resident physicians training in the ED, and 26 ED nurses were surveyed while on duty in the ED; 2) 27 family physicians providing walk-in or urgent care and attending a continuing medical education (CME) event were also surveyed. Respondents were asked to identify where to apply compression to the nose and how patients should be positioned during acute epistaxis.

Results

Regarding where to apply compression, 19% of family physicians, 43% of EM physicians, 24% of residents, and 8% of ED nurses responded correctly. Regarding positioning, all groups responded similarly with 54–62% responding correctly. Twenty-one percent of emergency physicians, 19% of residents, 11% of family physicians, and 4% of nurses responded correctly to both questions.

Conclusions

Most family physicians, EM attending physicians, ED nurses, and residents could not correctly identify basic first-aid measures for acute epistaxis. This study identifies an area where knowledge is lacking and the potential for improvement in patient management and education.

Grapical Abstract

Simplified management of epistaxis

ABSTRACT

Primary care, urgent care, and emergency department providers periodically treat epistaxis, either as recurrent nosebleed or an acute persistent episode. Silver nitrate application to the decongested and anesthetized nasal mucosa addresses the former in most cases. The plethora of commercial nasal packing devices testifies to the discomfort, technical difficulty, and frustration associated with traditional gauze-packing methods. Inflatable anterior nasal balloon packs reliably control most nosebleeds. Addition of a Foley catheter nasopharyngeal balloon pack manages most posterior epistaxis. Cautery and the two packing techniques mentioned above should treat most cases not requiring otolaryngology consultation or interventional radiology. Appropriate anesthetic and analgesics lessen the unpleasantness for both the patient and the provider. Topical moisturizing facilitates mucosal healing. Oxymetazoline 0.05% nasal spray provides the patient means to address rebleeding after discharge from treatment.

Diagnostic testing for SARS-CoV-2 infection in HHT patients: nasopharyngeal versus oropharyngeal swab

On March 11, 2020, WHO has defined the novel coronavirus disease SARS-CoV-2 (COVID-19) outbreak as a pandemic that still today continues to affect much of the world. Among the reasons for the rapid spread of SARS-CoV-2 infection, there is the role of asymptomatic or minimally symptomatic carriers. Therefore diagnostic testing is central to contain the global pandemic. Up to now real-time reverse transcriptase polymerase chain reaction-based molecular assays for detecting SARS-CoV-2 in respiratory specimens is the current reference standard for COVID-19 diagnosis. Based on current knowledge regarding the sensitivity of the molecular test, the highest positive detection rate is from lower respiratory tract specimens; alternatively it is possible to perform a nasopharyngeal or oropharyngeal swab. Nasopharyngeal swab is the preferred choice for SARS-CoV-2 testing since it seems to have a greater sensitivity; however the procedure is not always free of complications and an epistaxis can occur. Among patients with greatest risk of massive nosebleed there are HHT patients. Hereditary hemorrhagic telangiectasia is an autosomal dominant disease that leads to multiregional mucocutanous telangiectases and visceral arteriovenous malformations. Clinically, the presence of telangiectases in nasal mucosa is the cause of recurrent epistaxis. In HHT patients the execution of the nasopharyngeal swab can determine from little or no consequences to a massive epistaxis leading to the necessity of nasal packing generally followed by hospital admission. In HHT patients undergoing a diagnostic test to evaluate the SARS-CoV-2 infection status, especially in those patients with frequent epistaxis with a history of anemia and repeated hospitalizations, it is therefore advisable to perform an oropharyngeal swab. This, compared to the nasopharyngeal swab, exposes to a lower risk of severe nosebleeds related treatments, such as blood transfusions or invasive procedures. According to the risk-benefit assessment and based on our experience, we consider that, despite a lower diagnostic sensitivity, oropharyngeal swab is preferable to nasopharyngeal swab for the diagnosis of SARS CoV-2 infection in patients with HHT.

The role of endoscopic sphenopalatine artery ligation in the management of persistent epistaxis - A 15-year single-center experience

PURPOSE

Managing persistent epistaxis poses a great challenge for the otolaryngologist. Despite continuous development in treatment methods, no universal guideline has been commonly adopted. Among the popular methods is endoscopic sphenopalatine artery ligation (ESPAL). This study aims to evaluate the impact of ESPAL integration on persistent epistaxis management over 15 years in a single academic center.

METHODS

A retrospective study including all cases who were hospitalized due to persistent epistaxis and required intervention between 2000 and 2016. From 2011, ESPAL was routinely utilized in our center, hence the study population was divided based on admission year, prior to 2011 (pre-ESPAL) and from 2011 till the end of data collection (post-ESPAL).

RESULTS

The pre-ESPAL group included 87 interventions and the post-ESPAL group 54 interventions. Electrocautery remained the most common intervention in both periods. However, ESPAL incorporation was accompanied by a significant decline in the use of posterior nasal packing in the post-ESPAL group. The hemoglobin recovery levels and the mortality rates were significantly improved in the post-ESPAL group compared with the pre-ESPAL group despite higher comorbidity rates among the post-ESPAL patients.

CONCLUSIONS

This study demonstrates the shifting trend in managing persistent epistaxis, and suggests that ESPAL has successfully replaced posterior nasal packing. These findings may encourage clinicians to consider ESPAL as a valuable tool in the management of persistent epistaxis.

Prevalence and characteristics of S-point bleeding compared to non S-point bleeding in severe epistaxis

Introduction

Stamm's S-point is gaining importance as a bleeding focus in severe epistaxis. However, prevalence and features of S-point bleeding compared to non S-point bleeding have not been studied.

Objective

To investigate the characteristics of patients with S-point bleeding among those with severe epistaxis and to compare the factors involved in the treatment of epistaxis.

Methods

We retrospectively analyzed medical records of 268 patients admitted to the otorhinolaryngology department of Konkuk University Hospital and Chung-Ang University Hospital with epistaxis of which the bleeding focus clarified. Patients with anterior nasal bleeding (n = 129) were excluded. The study was conducted at the department of otorhinolaryngology from January 2008 to August 2019. Collected data included patients’ demographic information, bleeding focus, body mass index underlying medical and sinonasal diseases, laboratory test results (initial hemoglobin, platelet count, and triglyceride level), use of anticoagulants, direction of epistaxis, initial and final treatments, and need for blood transfusion.

Results

The prevalence of S-point bleeding was 28.8% of non-anterior bleeding cases. Mean body mass index score was lower in the S-point group (23.41 ± 3.71) compared to the non S-point group (24.93 ± 3.97) (p = 0.039). Underweight patients tended to show a greater incidence of S-point bleeding (15.0%) than non S-point bleeding (2.0%) (p = 0.010). Incidence of anemia was higher in the S-point group (67.5%) than in the non S-point group (36.4%). Anemia (Odds ratio [OR]: 3.635; 95% confidence interval [CI]: 1.669-7.914, p = 0.001) and underweight (body mass index < 18.5, OR: 8.559, CI: 1.648-44.445, p = 0.011) were significantly associated with S-point bleeding.

Conclusion

Prevalence of S-point bleeding was significant, underlining the importance of examining the S-point in patients with severe epistaxis. Patients with S-point bleeding had lower body mass index scores and a higher incidence of anemia than those with non S-point bleeding.

Algorithm-Based Pediatric Otolaryngology Management During the COVID-19 Global Pandemic: A Children’s Hospital of Philadelphia Clinical Consensus

Objective

The coronavirus disease 2019 (COVID-19) pandemic requires clinicians to explore alternatives to routine patient management. Otolaryngologists caring for children commonly depend on physical examination, laboratory data, and ambulatory surgical procedures. Limiting patient care, mindful allocation of resources, and concern for safety have challenged all aspects of our health care system. This evidence-based clinical consensus is designed to guide practitioners of pediatric otolaryngology for common scenarios during this time.

Data Sources

Peer-reviewed literature, published reports, institutional guidelines, and expert consensus.

Review Methods

A clinical consensus on 6 common scenarios in pediatric otolaryngology developed with evidence-based strategies.

Conclusions

Providers should suspend all in-person nonessential office visits and elective surgical procedures. An emphasis on medical management and caregiver education will provide reasonable approaches to many of the common outpatient concerns. Surgery for chronic otitis media, obstructive sleep apnea, and acute rhinosinusitis should occur only in response to severe complications or failure of medical regimens. The approach to the pediatric neck mass focuses on timely management for oncologic etiologies and cautious surgical intervention for abscess drainage or tissue sampling. Finally, epistaxis and otorrhea must be triaged and addressed without the usual ambulatory procedures.

Implications for Practice

Adaptation of practice patterns during this unprecedented moment for our health care system requires thoughtful planning. The strategies described allow for safe handling of common pediatric otolaryngology diagnoses. Ultimately, otolaryngologists must be stewards of our global health community while advocating for the care of individual pediatric patients.
