RESUMO
PURPOSE: The aim of this study was to assess whether hematological indices of the peripheral blood are associated with revision surgery in patients with chronic rhinosinusitis (CRS) undergoing endoscopic sinus surgery (ESS). METHODS: This retrospective, cross-sectional, single-center study included 541 CRS patients that underwent ESS. Demographics and laboratory parameters were retrieved, and group comparisons were performed. We computed binary logistic regression models to associate clinical characteristics (i.e., aeroallergen allergies, asthma, presence of nasal polyps), absolute blood counts of different leukocyte types (i.e., lymphocytes, neutrophils, basophils, and eosinophils), and hematological indices of the peripheral blood [i.e., neutrophil-to-lymphocyte ratio (NLR), basophil-to-lymphocyte ratio (BLR), eosinophil-to-lymphocyte ratio (ELR), and eosinophil-to-neutrophil ratio (ENR)] with revision surgery as outcome. RESULTS: The study population included 435 primary surgeries and 106 revision cases. Patients undergoing revision ESS showed significantly higher absolute preoperative eosinophil counts (381.6 ± 265.6 per µl), ELR (0.205 ± 0.195), and ENR (0.105 ± 0.074) compared to primary cases (all p < 0.001). Binary logistic regression analysis revealed higher odds for revision surgery in patients higher in age (ß = 1.026, p < 0.001), with presence of aeroallergen allergies (ß = 1.865, p = 0.011), presence of asthma (ß = 3.731, p = 0.001), higher preoperative eosinophil counts (ß = 1.002, p < 0.001), and higher ELR (ß = 155.663, p = 0.015). CONCLUSIONS: We found that higher peripheral eosinophil count and higher ELR were associated with revision ESS in CRS patients. Preoperative assessment of hematological indices of the peripheral blood might be a valuable indicator of disease severity, thus facilitating better treatment selection.

OBJECTIVES: Olfactory dysfunction (OD) is a common symptom of Coronavirus Disease 2019 (COVID-19). Although many patients have been reported to regain olfactory function within the first month, long-term observation reports vary. Therefore, we aimed to assess the course of chemosensory function in patients diagnosed with COVID-19 within 3-15 months after the infection. METHODS: One hundred and two patients (71 females and 31 males; mean age 38.8 years) diagnosed with laboratory-confirmed COVID-19 and subjective OD participated in this single-center study 111-457 days after onset of OD. Patients first performed chemosensory tests at home, followed by psychophysical testing (Sniffin' Sticks (TDI), 27-item Candy Smell Test (CST), Taste Strips Test (TST)) in the clinic. Questionnaires regarding importance of olfaction (IOQ) and olfactory-specific quality of life (QOD) were applied at both timepoints. RESULTS: After a mean 216 days (SD 73; range 111-457) between OD onset and follow-up testing, the mean Sniffin' Sticks (TDI) score was 27.1 points (SD 5.8; range 4.25-38.5): 4.0% were anosmic, 72.5% hyposmic, and 23.5% normosmic. At follow-up testing, 73.5% of patients reported improvement, 5.9% deterioration, and 20.6% no change in OD. Moreover, full recovery of self-perceived smell, flavor, and taste was not observed. According to questionnaires, the individual importance of smell did not change, but participants showed improvement in OD-related quality of life (p < 0.001) and had increased parosmia scores (p = 0.014) at follow-up. CONCLUSION: Our results show that long-lasting OD after SARS-CoV-2 infection is a common symptom. The majority of patients had OD in the range of hyposmia, which was confirmed by comprehensive smell tests.

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.

PURPOSE: Testing olfaction should be an integral part of a clinical work-up in rhinosurgical procedures. Importantly, intact olfactory experience also includes retronasally perceived odors (retronasal olfaction). This study aimed at comprehensively assessing olfaction in patients undergoing rhinosurgical procedures in a comparative manner and evaluating relations to patient-reported outcome measurements (PROMs). METHODS: Each nostril odor threshold and discrimination, and birhinal identification were tested using Sniffin' Sticks in 14 subjects assigned for septoplasty (SP), 21 for septorhinoplasty (SRP), and 30 for endoscopic sinus surgery (ESS). The 27-Candy-Smell-Test was used to quantify retronasal abilities. Tests were repeated 3 months after surgery. RESULTS: Olfactory dysfunction was preoperatively present in 21% of SP, in 47.6% of SRP, and in 80% of ESS patients. Odor threshold side differences were most frequently found in SRP. Frequently, SRP and ESS patients showed severely impaired retronasal olfaction. Half of included subjects re-visited after 3 months, but olfactory function did not improve overall and rarely on an individual basis to a meaningful extent. Subjective ratings on nasal patency and PROMs were not associated with olfaction nor with changes in olfactory scores. CONCLUSION: Olfactory function can decisively be impaired a priori not only in patients awaiting sinus surgery, but also in those assigned for functional septorhinoplasty. This impairment may not improve in the short term, which has to be taken into account in patient counseling. This study adds to the current literature on olfaction in rhinosurgery with the extension of retronasal testing.

PURPOSE: While the overall impact of chronic rhinosinusitis (CRS) on patients' health is diverse, many affected individuals have a substantially impaired quality of life (QoL). The aim of this study was to evaluate the impact of sex-associated differences specifically in the subgroups of CRS with nasal polyps (CRSwNP) and aspirin-exacerbated respiratory disease (AERD) by assessing QoL parameters in women and men separately. METHODS: In a retrospective single-center study, 59 patients with CRSwNP (39 males and 20 females) and 46 patients with AERD (18 males and 28 females) were included. Patient-reported outcome measures (PROM) evaluating QoL via the Sino-Nasal Outcome Test-20 German Adapted Version (SNOT-20 GAV) as well as the total polyp score (TPS) were analysed. RESULTS: There was no significant difference in TPS (p = 0.5550) and total SNOT-20 GAV scores (p = 0.0726) between male or female patients with CRSwNP or AERD. Furthermore, no significant sex differences were found within disease groups regarding the subcategories of the SNOT-20 GAV items. CONCLUSION: Thus, quality of life is severely impaired in patients suffering from various forms of CRS regardless of their sex.

PURPOSE: Epistaxis represents the most frequent ear, nose, throat-related emergency symptom. Seasonal variation in epistaxis incidence, with peaks during winter months, is widely accepted, although the literature itself remains inconclusive. The objective of this study was to evaluate public inquiry into nose bleeding, by considering Google-based search query frequency on "Epistaxis"-related search terms and to assess possible seasonal variations globally. METHODS: Epistaxis-related search terms were systematically collected and compared using Google Trends (GT). Relative search volumes for the most relevant epistaxis-related terms, covering a timeframe from 2004 to 2019 were analysed using cosinor time series analysis for the United States of America, Germany, the United Kingdom, Italy, Canada, Australia, and New Zealand. RESULTS: Graphical representation revealed seasonal variations with peaks during winter months in the majority of countries included. Subsequent cosinor analysis revealed these variations to be significant (all p < 0.001). CONCLUSION: Public interest in seeking epistaxis-related information through the Internet displayed seasonal patterns in countries from both hemispheres, with the highest interest during winter months. Further studies exploring causality with environmental factors are warranted.

PURPOSE: Olfactory training is recommended in olfactory dysfunction (OD) showing promising results. OD patients frequently ask for training modifications in the hope of a better outcome. Also, a lack of knowledge of the flavor system is evident. This investigation sought to implement flavor education (FE) and encourage patients to experience flavors in terms of a flavor training (FT). METHODS: In included patients (n = 30), OD was either of postinfectious (86.7%) or posttraumatic (13.3%) cause. Chemosensory abilities were tested orthonasally (using Sniffin Sticks = TDI) and retronasally (using the Candy Smell Test = CST). Key points of flavor perception were demonstrated in an educative session. Subjects were instructed to consciously experience flavors out of a list of 50. Effects of FT were explored in two groups (group A and B), with group B starting FT 17 weeks later. RESULTS: FE was appreciated and drop-out rate stayed very low (one participant). Compliance was high and 30.4 ± 12.9 flavors were tried. Overall TDI scores improved in 10 patients (6 group A, 4 group B) in a clinically significant way (> 5.5). For group A (starting FT earlier) rm-ANOVA showed a significant effect of session (timepoint) on CST (p < 0.01). CONCLUSION: Flavor education is demonstrated as feasible and appreciated in a clinical setting. FT seems to be a welcomed second-line therapy in patients with olfactory dysfunction. This study shows beneficial trends of FT; however, further studies with larger sample sizes and standardized training protocols are needed.

OBJECTIVE: Assessment of gustatory function in human subjects using the 'taste strips' test is an easy and validated procedure. The aim of this study was to extend this test in order to detect subjects with superior gustatory sensitivity. METHODS: The investigation included 134 subjects (29.5±12.6 years, range 18-84 years) with normal gustatory function. Four concentrations of sweet, sour, salty, and bitter were augmented with additional low concentrations (sweet: 25/12.5 mg/ml sucrose; sour: 27/15 mg/ml citric acid; salty: 6.4/2.6 mg/ml sodium chloride, bitter: 0.15/0.06 mg/ml quinine hydrochloride), resulting in a maximum extended taste score (ETS) of 24. RESULTS: The mean ETS was 14.5 ± 3.2. Specifically, it was 4.5 ± 1.2 for sweet, 2.8 ± 1.0 for sour, 4.0 ± 1.3 for salty, and 3.2 ± 1.2 for bitter. In contrast to the original version of the taste strips test, no ceiling effect was observed. Cluster analysis separated three groups of subjects by ETS, whereas test scores derived from the original four concentrations were insufficient to discriminate the subgroup with higher gustatory sensitivity. CONCLUSIONS: The extended taste strips test seems to be a useful tool for the detection of patients with low gustatory thresholds for sweet, sour, salty, or bitter taste.

OBJECTIVE: Despite the significance of trigeminal pathology, practical clinical tests that accurately evaluate intranasal trigeminal function are scarce. The aim of the present study is to introduce a practical procedure for the assessment of intranasal trigeminal sensitivity. METHODS: We developed a device to stimulate the nasal mucosa using carbon dioxide, which is self-administered intranasally by holding down a timed button until the required sensory response has been triggered. The trigeminal sensitivity is derived from the measured administration time in conjunction with the concentration of carbon dioxide administered. Sixty-three healthy participants were used to validate the device, after which the new device was compared with a standard lateralization task in an additional 16 participants. In 20 participants, the experiment was repeated to verify test-retest reliability. RESULTS: Statistical analysis showed significant consistency in administration-duration in healthy individuals, including those in the test-retest group. Those participants with higher scores in the lateralization task were found to show higher intranasal sensitivity measured by the new device. CONCLUSION: Herein, we present the design and validation of a novel device for the practical assessment of intranasal trigeminal sensitivity. In this study, we demonstrate the efficacy and reliability of this device.

The plasticity of brain function, especially reorganization after stroke or sensory loss, has been investigated extensively. Based upon its special characteristics, the olfactory system allows the investigation of functional networks in patients with smell loss, as it holds the unique ability to be activated by the sensorimotor act of sniffing, without the presentation of an odor. In the present study, subjects with chronic peripheral smell loss and healthy controls were investigated using functional magnetic resonance imaging (fMRI) to compare functional networks in one of the major olfactory areas before and after an olfactory training program. Data analysis revealed that olfactory training induced alterations in functional connectivity networks. Thus, olfactory training is capable of inducing neural reorganization processes. Furthermore, these findings provide evidence for the underlying neural mechanisms of olfactory training.

Objective: Item response theory (IRT) is a methodological approach to studying the psychometric performance of outcome measures. This study aims to determine and summarize the use of IRT in otolaryngological scientific literature. Methods: A systematic search of the Medline, Embase, and the Cochrane Library databases was performed for original English-language published studies indexed up to January 28, 2023, per the following search strategy: ("item response theory" OR "irt" OR "rasch" OR "latent trait theory" OR "modern mental test theory") AND ("ent" OR "otorhinolaryngology" OR "ear" OR "nose" OR "throat" OR "otology" OR "audiology" OR "rhinology" OR "laryngology" OR "neurotology" OR "facial plastic surgery"). Results: Fifty-five studies were included in this review. IRT was used across all subspecialties in otolaryngology, and most studies utilizing IRT methodology were published within the last decade. Most studies analyzed polytomous response data, and the most commonly used IRT models were the partial credit and the rating scale model. There was considerable heterogeneity in reporting the main assumptions and results of IRT. Conclusion: IRT is increasingly being used in the otolaryngological scientific literature. In the otolaryngology literature, IRT is most frequently used in the study of patient-reported outcome measures and many different IRT-based methods have been used. Future IRT-based outcome studies, using standardized reporting guidelines, might improve otolaryngology-outcome research sustainably by improving response rates and reducing patient response burden. Level of evidence: 2.
RESUMO
Objectives: The aim of the present study was to follow the daily course of patients with olfactory dysfunction and healthy controls and to assess (i) how many times a day, (ii) at which time, and (iii) in which aspect of daily life participants are conscious about their sense of smell. Methods: In this longitudinal study, 49 patients with smell loss and 30 healthy participants were enrolled. Olfactory function was assessed using the Sniffin' Sticks. All participants received paper diaries designed for a 14-day period, featuring 12 rows representing 12 daily hours and six columns for various daily life aspects. They were instructed to mark their awareness of smell by indicating the relevant row and column in the diary. Following the return of the diaries, a second olfactory test was conducted within the patient group. Results: On average, patients were consciously aware of their sense of smell around 8 times daily, while healthy participants noted it about 6.5 times a day. Both groups primarily focused on their sense of smell during activities related to "eating," followed by considerations in "social life" and "personal hygiene." Interestingly, distinct patterns emerged: patients peaked in awareness at 8 a.m. and 7 p.m., whereas healthy individuals showed peaks at 6 a.m., 12 p.m., and 7 p.m. Despite regular diary use, we observed no improvement in patients' olfactory function or related quality of life. Conclusion: The olfactory diary is a valuable tool unveiling individual smell awareness patterns in patients with smell loss, aiding in counseling and patient management. Level of Evidence: 4.
RESUMO
BACKGROUND: The common cold is the most widespread viral infection in humans. Iota-carrageenan has previously shown antiviral effectiveness against cold viruses in clinical trials. This study investigated the efficacy of a carrageenan-containing nasal spray on the duration of the common cold and nasal fluid viral load in adult patients. METHODS: In a randomized, double-blind, placebo-controlled trial, 211 patients suffering from early symptoms of the common cold were treated for seven days. Application was performed three times daily with either a carrageenan-supplemented nasal spray or saline solution as placebo with an overall observation period of 21 days. The primary endpoint was the duration of disease defined as the time until the last day with symptoms followed by all other days in the study period without symptoms. During the study, but prior unblinding, the definition of disease duration was adapted from the original protocol that defines disease duration as the time period of symptoms followed by 48 hours without symptoms. RESULTS: In patients showing a laboratory-confirmed cold virus infection and adherence to the protocol, alleviation of symptoms was 2.1 days faster in the carrageenan group in comparison to placebo (p = 0.037). The primary endpoint that had been prespecified but was changed before unblinding was not met. Viral titers in nasal fluids showed a significantly greater decrease in carrageenan patients in the intention-to-treat population (p = 0.024) and in the per protocol population (p = 0.018) between days 1 and 3/4. CONCLUSIONS: In adults with common cold virus infections, direct local administration of carrageenan with nasal sprays reduced the duration of cold symptoms. A significant reduction of viral load in the nasal wash fluids of patients confirmed similar findings from earlier trials in children and adults. TRIAL REGISTRATION: Current Controlled Trials ISRCTN80148028.

OBJECTIVES: The aim of this review is to examine the causes, pathophysiology and experimental models of non-infectious pharyngitis (sore throat). INTRODUCTION: The causes of sore throat can be infectious (viruses, bacteria, and fungi) or non-infectious, although the relative proportion of each is not well documented. METHODS: A PubMed database search was performed for studies of non-infectious sore throat. RESULTS AND CONCLUSIONS: Non-infectious causes of sore throat include: physico-chemical factors, such as smoking, snoring, shouting, tracheal intubation, medications, or concomitant illness; and environmental factors including indoor and outdoor air pollutants, temperature and humidity, and hazardous or occupational irritants. The pathophysiology underlying non-infectious sore throat is largely uncharacterised, although neurogenic inflammation looks to be a promising candidate. It is likely that there will be individual disposition factors or the coincidence of more than one irritant with possible--up to now unknown--interactions between them. Therefore, experimental models with defined conditions and objective endpoints are needed. A new model using cold dry air to directly induce pharyngeal irritation in humans, with pharyngeal lavage to measure biomarkers, may provide a useful tool for the study of mechanisms and treatment of non-infectious sore throat.

Background: The objective of this study was to determine how clinical characteristics and validated quality of life (QoL)-measures are associated with eating behavior in patients with olfactory dysfunction (OD). Methods: For this cross-sectional study, 150 OD patients of different causes were retrospectively recruited. Olfactory function was measured using the Sniffin' Sticks (TDI), while olfactory-related QoL was evaluated with the Questionnaire of OD negative and positive statements (QOD-NS and QOD-PS). The importance of olfaction was measured using the Importance of Olfaction Questionnaire (IOQ). The Dutch Eating Behavior Questionnaire (DEBQ) assessed eating behavior based on emotional, external, and restrained eating. Associations were sought between eating behavior metrics (as dependent variables) with clinical characteristics and olfactory-related outcome measures. Results: Emotional, external, and restrained eating behavior deviating from normative standards were reported in 54%, 71.3%, and 68% of patients, respectively. Multivariate regression modeling revealed that emotional eating was associated with age (ß = -0.227, p = 0.032), the body mass index (BMI, ß = 0.253, p = 0.005), the TDI (ß = 0.190, p = 0.046), and the QOD-NS (ß = 0.203, p = 0.049). External eating was associated with OD duration (ß = 0.291, p = 0.005), the TDI (ß = 0.225, p = 0.018), the QOD-PS (ß = -0.282, p = 0.008), and the IOQ (ß = 0.277, p = 0.004). Restrained eating was associated with age (ß = 0.216, p = 0.033), the BMI (ß = 0.257, p = 0.003), male gender (ß = -0.263, p = 0.002), and the IOQ (ß = 0.332, p < 0.001). Conclusion: Clinical characteristics and olfactory outcome measures differentially impact eating styles in OD patients. Our study's results highlight the importance of considering unfavorable changes in eating behavior during clinical counseling.
RESUMO
OBJECTIVES: Patients with olfactory dysfunction (OD) frequently report symptoms of depression. The objective of this study was to determine how clinical characteristics and olfactory-related quality of life (QoL) measures associate with the likelihood for major depressive disorders (MDDs). METHODS: A total of 192 OD patients were included. Olfactory function was measured using all three subtests of the Sniffn' Sticks test. Olfactory-related quality of life (QoL) was evaluated using the Questionnaires of Olfactory Dysfunction (QOD)-negative (NS) and -positive statement (PS). The likelihood for MDD was assessed using the Patients Health Questionnaire-2 (PHQ-2). Demographics and disease-specific variables (etiology and duration of OD) were collected. Univariate and multivariable analyses were used to associate disease-specific variables and the QOD with the outcome of the PHQ-2. Additionally, the predictive ability of the QOD-NS to predict depressive symptoms was calculated. RESULTS: In univariate analysis, COVID-19 related smell loss, the QOD-NS, and the QOD-PS were significantly associated with the PHQ-2. In multivariable analyses adjusting for QoL measures, the QOD-NS (ß = 0.532, p < 0.001) and sinonasal OD (compared with postinfectious OD) were significantly associated with the PHQ-2 (ß = 0.146, p = 0.047). When omitting QoL measures from multivariable analyses, only COVID-19 related OD (compared with postinfectious OD) was significantly associated with the PHQ-2 (ß = 0.287, p = 0.009). A QOD-NS score > 20.5 had 70.13% sensitivity and 76.32% specificity for detecting symptoms of depression. CONCLUSION: Our results suggest that COVID-19 related OD might be associated with a higher likelihood for MDD. Furthermore, we showed that the QOD-NS score might be helpful to predict symptoms of depression in OD patients. LEVEL OF EVIDENCE: 4 Laryngoscope, 132:1829-1834, 2022.

BACKGROUND: Previous studies provided the first evidence that the importance of olfaction decreases with the duration of olfactory dysfunction (OD). OBJECTIVE: To evaluate differences in olfactory-related quality of life (QoL) between patients with new-onset and persistent smell loss (>4 weeks) during the coronavirus-19 (COVID-19) pandemic and patients with persistent postinfectious OD (PIOD) that were recruited before the pandemic. METHODS: This was a retrospective study that included 149 patients with self-reported OD. The olfactory-related QoL was measured using the questionnaire of OD (QOD). The QOD measures the degree to which patients (i) adjust and cope with smell loss (QOD-positive statement [QOD-PS]), (ii) suffer from distorted odor perceptions (QOD-parosmia [QOD-PAR]), and (iii) suffer from smell loss in general (QOD-negative statement [QOD-NS]). Self-perceived chemosensory function, demographics, olfactory function, and duration of smell loss were evaluated. Analyses of variance were used to depict differences in QoL-outcomes between different OD groups. RESULTS: All patients included during the COVID-19 pandemic reported an extensive loss of chemosensory functions of smell, taste, and flavor perception. Psychophysical retronasal screening testing showed olfactory impairments in more than half of these patients. One-way analysis of variance and posthoc tests revealed that the QOD-NS was significantly higher in the new-onset OD group than the PIOD group. At the same time, the QOD-PS score was significantly higher in the PIOD and the persistent COVID-19 OD group than in the new-onset OD group. CONCLUSION: We showed that patients with persistent OD experienced better olfactory-related adjustment and lower QoL-impairment scores than those with recent-onset smell loss, suggesting that the olfactory-related QoL might change as a function of time after symptom onset.

Endoscopic sinus surgery (ESS) is performed in patients diagnosed with Chronic Rhinosinusitis (CRS) refractory to primary medical therapy to achieve adequate disease control. This study aimed to assess which factors and phenotypes of CRS are associated with revision surgery in patients undergoing ESS. This retrospective, single-center study included 667 patients undergoing ESS between 2012 and 2015. We performed group comparisons to detect differences between CRS patients undergoing primary or revision surgery and computed binary logistic regression models. Logistic regression analysis revealed higher odds for revision surgery in CRS patients with older age (p-value < 0.001), male gender (p-value = 0.011), diagnosis of AERD (p-value = 0.005), and presence of asthma (p-value < 0.001) or allergies (p-value = 0.031). Confirming previous studies, we found that the factors of age, CRSwNP, AERD, allergies, and asthma are associated with revision ESS and identified surgical techniques that were predominantly used in revision cases.
RESUMO
OBJECTIVE: Current epidemiologic predictions of COVID-19 suggest that SARS-CoV-2 mitigation strategies must be implemented long-term. In-office aerosol-generating procedures pose a risk to staff and patients while necessitating examination room shutdown to allow aerosol decontamination by indwelling ventilation. This review summarizes the current state of knowledge on portable high-efficiency particulate air (HEPA) purifiers' effectiveness in eliminating airborne SARS-CoV-2 from indoor environments. DATA SOURCES: Medline, Embase, Cochrane Databases, and the World Health Organization's COVID-19 Global Literature on Coronavirus Disease. REVIEW METHODS: Data sources were systematically searched for original English-language published studies indexed up to January 14, 2021 per the following search strategy: ("HEPA" OR "High-efficiency" OR "High-efficiency particulate air" OR "Efficiency particulate" OR "Purifier" OR "Filter" OR "Cleaner" OR "Filtration") AND ("COVID" OR "COVID-19" OR "SARS-CoV-2" OR "Coronavirus"). Additional relevant studies were identified by searching the reference lists of included articles. RESULTS: Eleven published studies have evaluated the effectiveness of portable HEPA purifiers in eliminating airborne SARS-CoV-2 with relevantly sized surrogate particles. Ten studies evaluated aerosols and submicron particles similar in size to SARS-CoV-2 virions. In all studies, portable HEPA purifiers were able to significantly reduce airborne SARS-CoV-2-surrogate particles. The addition of portable HEPA purifiers augmented other decontamination strategies such as ventilation. CONCLUSION: Experimental studies provide evidence for portable HEPA purifiers' potential to eliminate airborne SARS-CoV-2 and augment primary decontamination strategies such as ventilation. Based on filtration rates, additional air exchanges provided by portable HEPA purifiers may be calculated and room shutdown times potentially reduced after aerosol-generating procedures.

OBJECTIVE: Previous work has shown the chemosensory dysfunction item of the 22-item Sinonasal Outcome Test (SNOT-22) that assesses problems with "taste/smell" has poor psychometric performance compared with other items on the SNOT-22, which we have hypothesized is due to the simultaneous assessment of two different senses. Our aim was to determine whether distinct smell and taste items in the SNOT-22 would improve psychometric performance. METHODS: One hundred and eighty-one CRS patients were recruited and completed the SNOT-22. Additional items querying problems with the senses of "smell" and "taste," using the same response scale and recall period were given to study participants. Item response theory (IRT) was used to determine IRT parameters, including item discrimination, difficulty, and information provided by each SNOT-22 item. RESULTS: Confirming previous studies, the chemosensory item of the SNOT-22 (reflecting "taste/smell") had poor psychometric performance. Use of a distinct smell or taste item instead of the combined "taste/smell" item did not improve psychometric performance. However, a dedicated smell question resulted in a left shift of threshold parameters, showing that the dedicated smell item better captures moderate CRS disease burden than the original taste/smell item of the SNOT-22, which by virtue of near-identical IRT parameters appears to more greatly reflect problems with taste. CONCLUSIONS: A dedicated smell- or taste-specific item, rather than the combined "taste/smell" item currently in the SNOT-22 does not provide significantly greater psychometric performance. However, a dedicated smell item may better capture moderate CRS disease burden compared with the current chemosensory item on the SNOT-22. Laryngoscope, 132:1644-1651, 2022.
