Nonallergic Rhinopathy: A Comprehensive Review of Classification, Diagnosis, and Treatment.

Chronic nonallergic rhinitis syndromes encompass various conditions, of which vasomotor rhinitis is the most common form, representing approximately 80% of patients, also referred to as nonallergic rhinopathy (NAR), nasal hyperreactivity, neurogenic rhinitis, or idiopathic rhinitis. Expert panels have recommended replacing vasomotor rhinitis terminology because it is more descriptive of this condition that is characterized by symptoms triggered by chemical irritants and weather changes through chemosensors, mechanosensors, thermosensors, and/or osmosensors activated through different transient receptor potential calcium ion channels. Elucidating the specific role of transient receptor potential vanilloid 1, triggered by capsaicin, has been an important advancement in better understanding the pathophysiology of NAR because it has now been shown that downregulation of transient receptor potential vanilloid 1 receptors by several therapeutic compounds provides symptomatic relief for this condition. The classification of NAR is further complicated by its association with allergic rhinitis referred to as mixed rhinitis, which involves both immunoglobulin E-mediated and neurogenic mechanistic pathways. Comorbidities associated with NAR, including rhinosinusitis, headaches, asthma, chronic cough, and sleep disturbances, underscore the need for comprehensive management. Treatment options for NAR include environmental interventions, pharmacotherapy, and in refractory cases, surgical options, emphasizing the need for a tailored approach for each patient. Thus, it is extremely important to accurately diagnose NAR because inappropriate therapies lead to poor clinical outcomes and unnecessary health care and economic burdens for these patients. This review provides a comprehensive overview of NAR subtypes, focusing on classification, diagnosis, and treatment approaches for NAR.

Clinical Practice Guideline: Immunotherapy for Inhalant Allergy.

OBJECTIVE: Allergen immunotherapy (AIT) is the therapeutic exposure to an allergen or allergens selected by clinical assessment and allergy testing to decrease allergic symptoms and induce immunologic tolerance. Inhalant AIT is administered to millions of patients for allergic rhinitis (AR) and allergic asthma (AA) and is most commonly delivered as subcutaneous immunotherapy (SCIT) or sublingual immunotherapy (SLIT). Despite its widespread use, there is variability in the initiation and delivery of safe and effective immunotherapy, and there are opportunities for evidence-based recommendations for improved patient care. PURPOSE: The purpose of this clinical practice guideline (CPG) is to identify quality improvement opportunities and provide clinicians trustworthy, evidence-based recommendations regarding the management of inhaled allergies with immunotherapy. Specific goals of the guideline are to optimize patient care, promote safe and effective therapy, reduce unjustified variations in care, and reduce the risk of harm. The target patients for the guideline are any individuals aged 5 years and older with AR, with or without AA, who are either candidates for immunotherapy or treated with immunotherapy for their inhalant allergies. The target audience is all clinicians involved in the administration of immunotherapy. This guideline is intended to focus on evidence-based quality improvement opportunities judged most important by the guideline development group (GDG). It is not intended to be a comprehensive, general guide regarding the management of inhaled allergies with immunotherapy. The statements in this guideline are not intended to limit or restrict care provided by clinicians based on their experience and assessment of individual patients. ACTION STATEMENTS: The GDG made a strong recommendation that (Key Action Statement [KAS] 10) the clinician performing allergy skin testing or administering AIT must be able to diagnose and manage anaphylaxis. The GDG made recommendations for the following KASs: (KAS 1) Clinicians should offer or refer to a clinician who can offer immunotherapy for patients with AR with or without AA if their patients' symptoms are inadequately controlled with medical therapy, allergen avoidance, or both, or have a preference for immunomodulation. (KAS 2A) Clinicians should not initiate AIT for patients who are pregnant, have uncontrolled asthma, or are unable to tolerate injectable epinephrine. (KAS 3) Clinicians should evaluate the patient or refer the patient to a clinician who can evaluate for signs and symptoms of asthma before initiating AIT and for signs and symptoms of uncontrolled asthma before administering subsequent AIT. (KAS 4) Clinicians should educate patients who are immunotherapy candidates regarding the differences between SCIT and SLIT (aqueous and tablet) including risks, benefits, convenience, and costs. (KAS 5) Clinicians should educate patients about the potential benefits of AIT in (1) preventing new allergen sensitizations, (2) reducing the risk of developing AA, and (3) altering the natural history of the disease with continued benefit after discontinuation of therapy. (KAS 6) Clinicians who administer SLIT to patients with seasonal AR should offer pre- and co-seasonal immunotherapy. (KAS 7) Clinicians prescribing AIT should limit treatment to only those clinically relevant allergens that correlate with the patient's history and are confirmed by testing. (KAS 9) Clinicians administering AIT should continue escalation or maintenance dosing when patients have local reactions (LRs) to AIT. (KAS 11) Clinicians should avoid repeat allergy testing as an assessment of the efficacy of ongoing AIT unless there is a change in environmental exposures or a loss of control of symptoms. (KAS 12) For patients who are experiencing symptomatic control from AIT, clinicians should treat for a minimum duration of 3 years, with ongoing treatment duration based on patient response to treatment. The GDG offered the following KASs as options: (KAS 2B) Clinicians may choose not to initiate AIT for patients who use concomitant beta-blockers, have a history of anaphylaxis, have systemic immunosuppression, or have eosinophilic esophagitis (SLIT only). (KAS 8) Clinicians may treat polysensitized patients with a limited number of allergens.

Assessment of Demographic Changes of Workforce Diversity in Otolaryngology, 2013 to 2022.

Importance: Given the growth of minoritized groups in the US and the widening racial and ethnic health disparities, improving diversity remains a proposed solution in the field of otolaryngology. Evaluating current trends in workforce diversity may highlight potential areas for improvement. Objective: To understand the changes in gender, racial, and ethnic diversity in the otolaryngology workforce in comparison with changes in the general surgery and neurosurgery workforces from 2013 to 2022. Design, Setting, and Participants: This cross-sectional study used publicly available data from the Accreditation Council for Graduate Medical Education and the Association of American Medical Colleges for 2013 to 2022, and included medical students and trainees in all US medical residency programs and allopathic medical schools. Main Outcomes and Measures: Average percentages of women, Black, and Latino trainees during 2 intervals of 5 years (2013-2017 and 2018-2022). Pearson χ2 tests compared demographic information. Normalized ratios were calculated for each demographic group in medical school and residency. Piecewise linear regression assessed linear fit for representation across time periods and compared rates of change. Results: The study population comprised 59 865 medical residents (43 931 [73.4%] women; 6203 [10.4%] Black and 9731 [16.2%] Latino individuals; age was not reported). The comparison between the 2 study intervals showed that the proportions of women, Black, and Latino trainees increased in otolaryngology (2.9%, 0.7%, and 1.6%, respectively), and decreased for Black trainees in both general surgery and neurosurgery (-0.4% and -1.0%, respectively). In comparison with their proportions in medical school, Latino trainees were well represented in general surgery, neurosurgery, and otolaryngology (normalized ratios [NRs]: 1.25, 1.06, and 0.96, respectively); however, women and Black trainees remained underrepresented in general surgery, neurosurgery, and otolaryngology (women NRs, 0.76, 0.33, and 0.68; Black NRs, 0.63, 0.61, and 0.29, respectively). The percentage of women, Black, and Latino trainees in otolaryngology all increased from 2020 to 2022 (2.5%, 1.1%, and 1.1%, respectively). Piecewise regression showed positive trends across all 3 specialties. Conclusions and Relevance: The findings of this cross-sectional study indicate a positive direction but only a modest increase of diversity in otolaryngology, particularly in the context of national demographic data. Novel strategies should be pursued to supplement existing efforts to increase diversity in otolaryngology.

International consensus statement on allergy and rhinology: Allergic rhinitis - 2023.

BACKGROUND: In the 5 years that have passed since the publication of the 2018 International Consensus Statement on Allergy and Rhinology: Allergic Rhinitis (ICAR-Allergic Rhinitis 2018), the literature has expanded substantially. The ICAR-Allergic Rhinitis 2023 update presents 144 individual topics on allergic rhinitis (AR), expanded by over 40 topics from the 2018 document. Originally presented topics from 2018 have also been reviewed and updated. The executive summary highlights key evidence-based findings and recommendation from the full document. METHODS: ICAR-Allergic Rhinitis 2023 employed established evidence-based review with recommendation (EBRR) methodology to individually evaluate each topic. Stepwise iterative peer review and consensus was performed for each topic. The final document was then collated and includes the results of this work. RESULTS: ICAR-Allergic Rhinitis 2023 includes 10 major content areas and 144 individual topics related to AR. For a substantial proportion of topics included, an aggregate grade of evidence is presented, which is determined by collating the levels of evidence for each available study identified in the literature. For topics in which a diagnostic or therapeutic intervention is considered, a recommendation summary is presented, which considers the aggregate grade of evidence, benefit, harm, and cost. CONCLUSION: The ICAR-Allergic Rhinitis 2023 update provides a comprehensive evaluation of AR and the currently available evidence. It is this evidence that contributes to our current knowledge base and recommendations for patient evaluation and treatment.

Otolaryngology Away Subinternships: An Analysis of the Application Process and Survey of Current Applicants' Perspectives.

Objective: To assess the availability and uniformity of application information for away subinternships and survey 4th-year medical students on their experiences obtaining away subinternships in otolaryngology-head and neck surgery (OHNS) during the 2022 to 2023 application cycle. Study Design: Cross-sectional study. Setting: Online survey. Methods: The Association of American Medical College's Visiting Student Learning Opportunities (VSLO) program was queried for information on OHNS away subinternship applications. A survey assessing 4th-year medical students' perceptions of the away subinternship application process was distributed via OHNS residency program directors and Otomatch. Results: Of 129 OHNS residency programs, 103 (80%) offered away subinternship opportunities on VSLO. Variability in application release dates (January 18 to June 3, 2022), offer release dates (January 27 to August 7, 2022), and estimated cost ($22-$5500) were found. The most common application requirements were a transcript (98.1%) and a CV/resume (90.3%). There were 64 survey respondents, for a 13% response rate. The most common concerns include applying to too few programs (80%) and not knowing offer release dates (77%). The most common stressors include choosing a number of programs to which to apply (48%) and cost (35%). The majority (76%) reported difficulty finding updated information on program websites. Among the proposed changes, the greatest support was found for having all applications on VSLO (88%), uniform application release date (84%), and uniform application requirements (82%). Conclusion: The OHNS away subinternship application process is a significant source of anxiety for medical students due to the tremendous variability in application and acceptance procedures. Having all applications on VSLO, uniform application requirements, and uniform application opening and offer release dates would better facilitate this process.

Nasal allergen challenge (NAC): Practical aspects and applications from an EU/US perspective-a Work Group Report of the AAAAI Rhinitis, Rhinosinusitis and Ocular Allergy Committee.

Nasal allergen challenge (NAC) is applied in a variety of settings (research centers, specialty clinics, and hospitals) as a useful diagnostic and research tool. NAC is indicated for diagnosis of seasonal and perennial allergic rhinitis, local allergic rhinitis, and occupational rhinitis; to design the composition of allergen immunotherapy in patients who are polysensitized; and to investigate the physio-pathological mechanisms of nasal diseases. NAC is currently a safe and reproducible technique, although it is time- and resource-consuming. NAC can be performed by a variety of methods, but the lack of a uniform technique for performing and recording the outcomes represents a challenge for those considering NAC as a clinical tool in the office. The availability of standardized allergens for NAC is also different in each country. The objective of this workgroup report is to review the current information about NAC, focusing on the practical aspects and application for diagnosis of difficult rhinitis phenotypes (eg, local allergic rhinitis, occupational rhinitis), taking into account the particular context of practice in the United States and the European Union.

Ganglioneuroblastoma Presenting as Obstructive Sleep Apnea in a 5-Year-Old Boy.

The authors present an interesting case of ganglioneuroblastoma, a tumor of the sympathetic chain, presenting as severe obstructive sleep apnea in a healthy 5-year-old boy. The patient's initial polysomnogram demonstrated an apnea-hypopnea index (AHI) of 86 events/hour. He underwent an adenotonsillectomy at an outside hospital and his repeat AHI was still 62. The patient was nonobese and nonsyndromic appearing, which made his incredibly high AHI perplexing. He underwent sleep endoscopy and direct laryngoscopy for further evaluation, which demonstrated a large mass in the left posterior pharynx. He then underwent surgical excision with a resolution of his obstructive sleep apnea.

Climate change, the environment, and rhinologic disease.

BACKGROUND: The escalating negative impact of climate change on our environment has the potential to result in significant morbidity of rhinologic diseases. METHODS: Evidence based review of examples of rhinologic diseases including allergic and nonallergic rhinitis, chronic rhinosinusitis, and allergic fungal rhinosinusitis was performed. RESULTS: The lower socioeconomic population, including historically oppressed groups, will be disproportionately affected. CONCLUSIONS: We need a systematic approach to improve healthcare database infrastructure and funding to promote diverse scientific collaboration to address these healthcare needs.

Effects of combination treatment with tezepelumab and allergen immunotherapy on nasal responses to allergen: A randomized controlled trial.

BACKGROUND: Thymic stromal lymphopoietin (TSLP) has been shown to play a central role in the initiation and persistence of allergic responses. OBJECTIVE: We evaluated whether tezepelumab, a human monoclonal anti-TSLP antibody, improved the efficacy of subcutaneous allergen immunotherapy (SCIT) and promoted the development of tolerance in patients with allergic rhinitis. METHODS: We conducted a double-blind parallel design trial in patients with cat allergy. A total of 121 patients were randomized to receive either intravenous tezepelumab plus subcutaneous cat SCIT, cat SCIT alone, tezepelumab alone, or placebo for 52 weeks, followed by 52 weeks of observation. Nasal allergen challenge (NAC), skin testing, and blood and nasal samples were obtained throughout the study. RESULTS: At week 52, the NAC-induced total nasal symptom scores (TNSS) (calculated as area under the curve [AUC0-1h] and as peak score [Peak0-1h] during the first hour after NAC) were significantly reduced in patients receiving tezepelumab/SCIT compared to SCIT alone. At week 104, one year after stopping treatment, the primary end point TNSS AUC0-1h was not significantly different in the tezepelumab/SCIT group compared to SCIT alone, while TNSS Peak0-1h was significantly lower in those receiving combination treatment versus SCIT. Transcriptomic analysis of nasal epithelial samples demonstrated that treatment with the combination of SCIT/tezepelumab, but neither monotherapy, caused persistent downregulation of a gene network related to type 2 inflammation that was associated with improvement in NAC responses. CONCLUSIONS: Inhibition of TSLP augments the efficacy of SCIT during therapy and may promote tolerance after a 1-year course of treatment. (ClinicalTrials.gov NCT02237196).

Review of evidence supporting the use of nasal corticosteroid irrigation for chronic rhinosinusitis.

OBJECTIVE: To analyze published reports on the efficacy and safety of CSI in CRS and evaluate the clinical implications of current gaps in evidence. Corticosteroid irrigation (CSI) is commonly used for management of chronic rhinosinusitis (CRS) with nasal polyps; however, such use is not approved by the US Food and Drug Administration (FDA). DATA SOURCES: Publications were obtained through PubMed searches through January 2022. STUDY SELECTION: Searches were conducted using 2 terms: "chronic rhinosinusitis" or "nasal polyps" as the first term and "corticosteroid irrigation," "steroid nasal lavage," or "sinus rinse" as the second term. We reviewed relevant, peer-reviewed literature (19 original research [9 controlled, 10 uncontrolled trials], 7 reviews, and 1 meta-analysis) reporting safety and efficacy of CSI in patients with CRS. RESULTS: Studies were difficult to compare because they used a variety of solution volumes (60 mL to 125 mL per nostril), corticosteroid agents (budesonide, betamethasone, mometasone, or fluticasone), corticosteroid doses, preparation protocols (by compounding pharmacy or by patient), and administration (frequency, time of day, body positioning). It is difficult to determine which parameters might substantially influence clinical effects because studies were generally small, showed marginal benefits, and rarely assessed safety. To date, no studies evaluating CSI have shown statistically significant differences in a type-I error-controlled primary end point over any comparator, possibly owing to small sample sizes. CONCLUSION: Designing more robust clinical trials may help determine whether CSI is a valid treatment option. Until more evidence supporting CSI use exists, health care professionals should strongly consider choosing FDA-approved therapies for the treatment of CRS.

Systemic Bevacizumab for Severe Recurrent Respiratory Papillomatosis.

Recurrent respiratory papillomatosis (RRP) is the most common benign pediatric laryngeal neoplasm. Various adjuvant medical therapies have failed to reliably decrease surgical frequency in this challenging airway disease. Recently, systemic bevacizumab has shown promise in advanced, treatment-resistant papillomatosis. We describe the use of systemic bevacizumab in two children with severe RRP unresponsive to other therapies. Voice and breathing improved dramatically in both patients with minimal side effects. Both patients have not required surgery in 24 months and 16 months, respectively. Systemic bevacizumab is a promising long-term treatment for severe RRP, with oncology playing an important role in patient care.

Yardstick for the medical management of chronic rhinosinusitis.

Chronic rhinosinusitis (CRS) is an inflammatory condition of the paranasal sinuses defined by classic symptoms, imaging findings, or endoscopic findings. There are a growing number of emerging pharmacologic therapies being evaluated to treat patients with CRS, some of which have gained indication status in the United States. There have not been updated treatment guidelines published in the United States however since 2014. This document is meant to serve as an updated expert consensus document for the pharmacologic management of patients with CRS. We review available data focusing on prospective clinical trials on oral and intranasal corticosteroids, nasal irrigation, biologics, antibiotics, and allergy immunotherapy for CRS both with and without nasal polyposis, including specific therapies for aspirin-exacerbated respiratory disease-associated CRS and allergic fungal CRS. There are multiple options to treat CRS, and clinicians should be knowledgeable on the efficacy and risks of these available therapies. Allergists-immunologists now have various therapies available to treat patients with CRS.

Improvement in Central Sleep Apnea Following Adenotonsillectomy in Children.

OBJECTIVE: Previous studies examining changes in central sleep apnea (CSA) following adenotonsillectomy (T&A) performed for obstructive sleep apnea (OSA) in children have been limited by sample size and analysis of only certain populations. The aim of this study was to determine whether CSA improves following T&A and what factors mediate this change. METHODS: This was a retrospective case series from 1994 to 2020 of children undergoing primary T&A for OSA (obstructive apnea-hypopnea index ≥1) with CSA (central apnea index [CAI] ≥1) and preoperative and postoperative polysomnograms within 12 months of T&A. Polysomnograms were analyzed for improvement in CSA, defined as: 1) if preoperative CAI >5, a postoperative CAI <5; or 2) if preoperative CAI <5, a postoperative CAI <1. RESULTS: One hundred twenty-three patients were included. Median age was 5.5 years (interquartile range, 2.9-8.4). Most patients were overweight/obese (58.5%). Nineteen (15.4%) had a syndromic condition. Preoperative CAI was ≥5 in 21 (17.1%) patients. CAI significantly decreased following T&A (preoperative 2.1, postoperative 0.4; P < .001). Thirty-two (26.0%) patients had CSA postoperatively. Improvement in the microarousal index and older age were significantly associated with improvement in CSA. CONCLUSIONS: T&A led to resolution of CSA in most children with OSA. Improvement in the microarousal index was associated with improvement in CAI, suggesting that preoperative central apneas may be postarousal and thus resolve following T&A.

Leveraging the universal newborn hearing screen to impact parental knowledge of childhood speech development in low socioeconomic populations: A randomized clinical trial.

OBJECTIVE: To determine the impact of a video intervention administered at the time of the universal newborn hearing screen on caregiver knowledge of infant cognitive and language development in low socioeconomic status English-speaking parents. METHODS: A parallel-group, single-blind randomized clinical trial was conducted from April to August 2016. Eligible participants were at least 18 years, delivered a singleton neonate, English speaking, and designated as low socioeconomic status based on household income and level of education. A total of 112 patients, 54 treatment and 58 control, completed the study and were included in the analysis. The Baby Survey of Parent/Provider Expectations and Knowledge, a validated 24-item questionnaire assessing child development knowledge, was the primary study outcome. The survey was conducted at baseline, 1 day after intervention, and 4-6 weeks later. A one-way, repeated measures analysis of variance (ANOVA) was employed to evaluate for differences in the three time points. RESULTS: The average age of participants was 25.6 years and 85% identified as African-American. There was no significant difference in scores prior to and following the intervention for the control group (N = 58, F = 1.67, p = 0.19); however, a significant difference in scores was found in the treatment group (N = 54, F = 7.95, p < 0.001). Post-hoc analysis showed a significant improvement in scores 1 day after intervention, but no difference 4-6 weeks later. CONCLUSION: Educational video intervention for low socioeconomic mothers at the time of the universal newborn hearing screen can positively increase knowledge related to hearing and language development in the short term.

Systemic Bevacizumab for Treatment of Respiratory Papillomatosis: International Consensus Statement.

OBJECTIVES/HYPOTHESIS: The purpose of this study is to develop consensus on key points that would support the use of systemic bevacizumab for the treatment of recurrent respiratory papillomatosis (RRP), and to provide preliminary guidance surrounding the use of this treatment modality. STUDY DESIGN: Delphi method-based survey series. METHODS: A multidisciplinary, multi-institutional panel of physicians with experience using systemic bevacizumab for the treatment of RRP was established. The Delphi method was used to identify and obtain consensus on characteristics associated with systemic bevacizumab use across five domains: 1) patient characteristics; 2) disease characteristics; 3) treating center characteristics; 4) prior treatment characteristics; and 5) prior work-up. RESULTS: The international panel was composed of 70 experts from 12 countries, representing pediatric and adult otolaryngology, hematology/oncology, infectious diseases, pediatric surgery, family medicine, and epidemiology. A total of 189 items were identified, of which consensus was achieved on Patient Characteristics (9), Disease Characteristics (10), Treatment Center Characteristics (22), and Prior Workup Characteristics (18). CONCLUSION: This consensus statement provides a useful starting point for clinicians and centers hoping to offer systemic bevacizumab for RRP and may serve as a framework to assess the components of practices and centers currently using this therapy. We hope to provide a strategy to offer the treatment and also to provide a springboard for bevacizumab's use in combination with other RRP treatment protocols. Standardized delivery systems may facilitate research efforts and provide dosing regimens to help shape best-practice applications of systemic bevacizumab for patients with early-onset or less-severe disease phenotypes.
