Objectives Urine leukotriene E4 (uLTE4) is a biomarker of leukotriene synthesis and is elevated in patients with aspirin‐exacerbated respiratory disease (AERD). It can also be useful to help delineate aspirin‐tolerant chronic rhinosinusitis with nasal polyposis (CRSwNP) patients from AERD patients. The purpose of this study is to determine if uLTE4 biomarker levels are associated with objective and subjective markers of disease severity in patients with CRSwNP. Methods A retrospective analysis of CRSwNP patients who underwent uLTE4 testing was completed to determine the association of uLTE4 levels to markers of disease severity. uLTE4 levels, as well as presenting subjective (Sinonasal Outcome Test 22 [SNOT22] scores, asthma control test [ACT] scores) and objective data (Lund‐Mackay CT score, spirometry and lab values) were collected. Results Among the 157 CRSwNP patients who met inclusion criteria, uLTE4 levels were associated with history of asthma (P < .001), aspirin sensitivity (P < .001), worse Lund‐Mackay CT scores (P = .002) and other objective markers of disease severity including serum IgE (P = .05), presenting blood eosinophil level (P < .001), and the highest recorded eosinophil level (P < .001). In subgroup analysis, associations of uLTE4 to disease markers had stronger correlations in the aspirin sensitive CRSwNP group (R range 0.31–0.52) than the aspirin tolerant CRSwNP group (R range −0.30–0.24). uLTE4 levels were not associated with subjective symptom scores (SNOT22 and ACT scores). Conclusion Elevated uLTE4 biomarker levels are associated with worsened objective markers of disease severity in CRSwNP patients but not patient‐reported symptom measures.

Objective: Determine the geographic and per capita distribution of otology-neurotology physician-surgeons within the United States. Study Design: National database review. Setting: United States. Methods: The American Neurotology Society and ENThealth.org membership databases were queried to identify otology-neurotology physician-surgeons within the United States. Physician-surgeons were divided by regional national census areas, state, and by largest population statistical area based on 2019 US Census population estimates. The number of otology-neurotology physician-surgeons per 1 million persons was calculated for each population designation. Results: Four-hundred eighty-two physician-surgeons were identified, representing 49 states and the District of Columbia. The New England division (Connecticut, Maine, Massachusetts, New Hampshire, Rhode Island) was the most concentrated region (1.89), whereas the West-South-Central (Texas, Oklahoma, Arkansas, Louisiana) was the least concentrated region (1.23) per million persons. The highest concentration of physician-surgeons by state is within the District of Columbia (4.25), Vermont (3.21), North Dakota (2.62), Massachusetts (2.61), and New York (2.21) (per million), whereas Mississippi (0.67), Georgia (0.66), Idaho (0.56), New Mexico (0.48), and Wyoming (0.0) were the least concentrated per million persons. Increasing number of physician-surgeons was significantly correlated by state (r 2 = 0.9; P < 0.0001), largest statistical area (r 2 = 0.88; P < 0.0001), and census region (r 2 = 0.95; P < 0.0005). Conclusions: Otology-neurotology physician-surgeons are evenly distributed across the United States; however, certain areas are likely underrepresented. Variability in clinical practice may account for under or overrepresentation not captured in this analysis.

Background: 2015 American Thyroid Association (ATA) guidelines recommended more conservative treatment in low-risk well-differentiated thyroid cancer (WDTC), stating that lobectomy alone may be sufficient. The guidelines further recommend mild thyroid-stimulating hormone (TSH) level suppression (0.5-2 mU/L) for this population. Our goal is to evaluate the natural history of patients undergoing lobectomy to determine the percentage that would require postoperative levothyroxine supplementation under these guidelines. Methods: Retrospective chart review of 168 patients that underwent lobectomy between 2010 and 2019 was performed. Preoperative and postoperative TSH values and the rate of patients prescribed levothyroxine were analyzed. Results: Thirty-five percent of patients were prescribed levothyroxine postoperatively. At 6 weeks postoperatively, 66% had TSH value of >2; this increased to 76% by 6 to 12 months. Conclusion: To adhere to ATA guidelines for WDTC managed with lobectomy alone, the majority of patients (76%) would require postoperative levothyroxine supplementation. Low preoperative TSH was found to be the most significant predictor for postoperative TSH < 2.
