Correlation of the Sinonasal Outcome Test-22 With the University of Washington Quality of Life in Assessing Quality of Life in Sinonasal Malignancy Utilizing a Multicenter Prospective Observational Cohort Registry.

In this multi-center sinonasal malignancies (SNM) cohort, the Sino-nasal Outcome Test has a correlation with the University of Washington Quality of Life (UWQOL) for assessing QOL. The use of both instruments remains recommended to provide complete and complementary information. Future design of an easy-to-use tool specific to SNM is needed to encompass all aspects of QOL.

Cross-sensitization between inhalant allergens and food allergens: the extent, intensity, and age-related shifts.

Background: Encountering individuals sensitized to both inhalant and food allergens is challenging in clinical practice. Despite its rarity, studies have documented cross-sensitization between these allergens. However, the extent, diversity, and age-related variations of this phenomenon remain unclear.

Impact of sociodemographic status and sex on chronic rhinosinusitis and olfaction in people with cystic fibrosis.

Background: Sociodemographic status (SDS) including race/ethnicity and socioeconomic status as approximated by education, income, and insurance status impact pulmonary disease in people with cystic fibrosis (PwCF). The relationship between SDS and chronic rhinosinusitis (CRS) remains understudied.

Methods: In a prospective, multi-institutional study, adult PwCF completed the 22-Question SinoNasal Outcome Test (SNOT-22), Smell Identification Test (SIT), Questionnaire of Olfactory Disorder Negative Statements (QOD-NS), and Cystic Fibrosis Questionnaire-Revised (CFQ-R).

University of Washington Quality of Life subdomain outcomes after treatment of sinonasal malignancy: A prospective, multicenter study.

Purpose: Sinonasal malignancies (SNMs) adversely impact patients' quality of life (QOL) and are frequently identified at an advanced stage. Because these tumors are rare, there are few studies that examine the specific QOL areas that are impacted. This knowledge would help improve the care of these patients.

Comparison of patient-reported outcomes and clinical characteristics among patients with pituitary macroadenomas and giant adenomas.

Patients with giant adenomas are more likely to have tumor extension into the paranasal sinuses. Compared to macroadenomas, giant adenomas are not associated with worse preoperative SNOT-22 scores.

SNOT-22 subdomain outcomes following treatment for sinonasal malignancy: A prospective, multicenter study.

Background: Patients with sinonasal malignancy (SNM) present with significant sinonasal quality of life (QOL) impairment. Global sinonasal QOL as measured by the 22-item Sinonasal Outcomes Test (SNOT-22) has been shown to improve with treatment. This study aims to characterize SNOT-22 subdomain outcomes in SNM.

Patient perspectives on chronic rhinosinusitis in cystic fibrosis: Symptom prioritization in the era of highly effective modulator therapy.

Background: Chronic rhinosinusitis (CRS) is common in people with cystic fibrosis (PwCF). Rhinologic symptom prioritization and areas that influence CRS treatment choices, including pursuing endoscopic sinus surgery (ESS), remain understudied.

Methods: Adult PwCF + CRS were enrolled at eight centers into a prospective, observational study (2019-2023).

Risk Factors Associated with Postoperative CSF Leak in Extrasellar Tumors.

 While postoperative cerebrospinal fluid (CSF) leak rates of pituitary tumors have been frequently studied, there are fewer studies examining postoperative CSF leak rates for extrasellar tumors. The purpose of this study was to identify risk factors for the development of postoperative CSF leak in patients undergoing endoscopic surgery for extrasellar tumors.  A retrospective chart review was done for patients who underwent endoscopic resection for extrasellar tumors between 2008 and 2020.

Determining the minimal clinically important difference for the questionnaire of olfactory disorders in people with cystic fibrosis and factors associated with improvement after highly effective modulator therapy.

Introduction: Olfactory dysfunction (OD) is common among people with cystic fibrosis (PwCF). The Questionnaire of Olfactory Disorders (QOD) is a validated instrument that evaluates olfactory-specific quality-of-life. The QOD minimal clinically important difference (MCID) and factors associated with olfactory improvement after elexacaftor/tezacaftor/ivacaftor have not been determined for PwCF.

Decreases in Rhinology Care Utilization by People with Cystic Fibrosis on Highly Effective Modulator Therapy.

Background: Many people with cystic fibrosis (PwCF) have chronic rhinosinusitis (CRS). CRS requires additional management beyond that of pulmonary disease and leads to increased utilization of healthcare resources. Elexacaftor/tezacaftor/ivacaftor (ETI) is a highly effective modulator therapy that has been shown to improve CRS in PwCF.

Factors that predict pursuing sinus surgery in the era of highly effective modulator therapy.

Background: Comorbid chronic rhinosinusitis (CRS) remains unresolved for many people with cystic fibrosis (PwCF). While highly effective modulator therapy improves quality-of-life and symptom severity, the impact of this intervention and other factors associated with pursuing endoscopic sinus surgery (ESS) remains understudied.

Methods: Adult PwCF + CRS were enrolled into a prospective, observational, multi-institutional study.

Predictive factors for decreased baseline quality of life in patients with sinonasal malignancies.

Background: The impact of sinonasal malignancies (SNMs) on quality of life (QOL) at presentation is poorly understood. The Sinonasal Outcome Test (SNOT-22) and University of Washington Quality of Life (UWQOL) are validated QOL instruments with distinctive subdomains. This study aims to identify factors impacting pretreatment QOL in SNM patients to personalize multidisciplinary management and counseling.

Fungal and Bacterial Microbiome in Sinus Mucosa of Patients with and without Chronic Rhinosinusitis.

Objectives: Dysbiosis of the sinonasal microbiome has been implicated in the pathogenesis of chronic rhinosinusitis (CRS). However, the mycobiome remains largely understudied, and microbial alterations associated with specific CRS subtypes have yet to be delineated. The objective of this study is to investigate the fungal and bacterial microbiome of sinus mucosa in CRS patients with and without nasal polyposis (CRSwNP and CRSsNP) versus healthy controls.

Safety of Antibiotic Irrigations for Acute Exacerbations of Chronic Rhinosinusitis in Patients with Identical Drug Allergies or Adverse Reactions: A Pilot Study.

The use of topical antibiotics in the treatment of acute exacerbation of chronic rhinosinusitis (AECRS) represents a viable option prior to initiation of parenteral antibiotics when no oral antibiotic alternatives are available due to patient allergy or adverse reactions. The main objectives of this pilot study were to determine the safety and efficacy of antibiotic irrigations in the treatment of AECRS in patients with documented adverse reactions to the oral form of the drug. A retrospective review was performed of patients diagnosed with AECRS treated with antibiotic irrigations.

Residential Proximity to a Commercial Pesticide Application Site and Risk of Chronic Rhinosinusitis.

Importance: Environmental and occupational toxicants have been shown to be associated with an increased prevalence of chronic rhinosinusitis (CRS). However, few to no studies have evaluated patients for CRS using objective testing and workup protocols that fulfill guidelines for CRS diagnostic criteria. Furthermore, no study, to our knowledge, has investigated the risks of CRS in the context of residential exposure through proximity to a commercial pesticide application site.

Long-term quality of life after treatment in sinonasal malignancy: A prospective, multicenter study.

In this study we evaluated how patient, treatment, and disease factors impact sinonasal-specific and generalized QOL using validated metrics in a large cohort over a 5-year posttreatment time frame.

Methods: Patients with SNM who underwent definitive treatment with curative intent were enrolled in a prospective, multisite, longitudinal observational study.

Comparison of body size perception of young women in Korea and the United States.

Body size perception among young women in Asian and Western countries is believed to be quite different, however, there are no confirming studies. We analyzed the data from young women aged between 20 and 40 who participated in the National Health and Nutrition Examination Survey (2001-2018) of the United States (US) and Korea. US young women had higher rates of being overweight and obesity than Korean young women, and there was no significant change over 20 years.

Endoscope-Assisted Pedicled Maxillary Artery to Middle Cerebral Artery Bypass: An Anatomic Feasibility Study.

Background: Extracranial to intracranial bypass is used to augment and/or replace the intracranial circulation for various pathologies. The superficial temporal artery is the mainstay donor for pedicled bypasses to the anterior circulation but can be limited by its variable size, low native flow rates, and potential scalp complications. Interposition grafts such as the radial artery or greater saphenous vein are alternatives but are sometimes limited by size mismatch, length needed to reach the extracranial circulation, and loss of inherent vascular elasticity.
