Introduction: Laryngopharyngeal symptoms (LPS) refer to aerodigestive complaints that may result from the retrograde flow of gastric contents into the upper aerodigestive tract. These symptoms may be under-recognised in populations exposed to mechanical or environmental stressors. Divers may be at increased risk due to factors such as pressure changes and body positioning. This study characterised the prevalence and severity of LPS among divers and identified associated risk factors. Methods: A cross-sectional, anonymous survey was distributed to members of the Divers Alert Network (DAN). Collected data included demographics, diving-related behaviours, medical history, and LPS burden measured using the Reflux Symptom Index (RSI). Results: Of the 309 survey responses analysed, 47.2% were male with a median age of 50.0 years (IQR: 40.0−60.0). Among 291 divers with complete RSI data, 26.1% (95% CI, 21.4–31.5%) had abnormal RSI scores, representing a +16.0 percentage-point increase (95% CI, 11.3%−21.4%) over non-diving population estimates (P < 0.001). In multivariable analysis, female sex (adjusted prevalence rate [aPR] 1.59, 95% CI 1.07–2.37) and gastroesophageal reflux disease (GERD) history (aPR 1.75, 95% CI 1.16–2.65) were independent predictors. Recreational divers had a lower risk (aPR 0.59, 95% CI 0.39–0.90). Approximately 5% of respondents described their symptoms as life-threatening. Conclusions: Divers may represent an under-recognised population at elevated risk for LPS. Female sex and GERD history were associated with greater symptom burden, while recreational diving appeared less provocative compared to technical diving. These findings may have implications for risk stratification and symptom management in the diving community.

Abstract Objective To evaluate the connection between symptom burden and sexual quality of life in women with idiopathic subglottic stenosis (iSGS). iSGS is a rare fibroinflammatory disorder involving progressive airway narrowing and respiratory distress. While the impact on physical functioning is well‐established, the influence of iSGS on sexual health, a key component of quality of life, remains unexplored. Study Design Anonymized cross‐sectional survey using validated questionnaires. Setting Online international iSGS support group (Living with Idiopathic Subglottic Stenosis). Methods The Dyspnea Index (DI), the Female Sexual Quality of Life (SQOL‐F) questionnaire, and the Medical Outcomes Health Survey (SF‐36) were distributed to an iSGS support group. Only complete responses were analyzed. Associations between DI and sexual quality of life were evaluated using correlation and linear regression. Median‐based symptom burden groupings were used for secondary descriptive comparisons. Results 682 completed all items in the assigned questionnaires and met inclusion criteria. DI scores were inversely correlated with SQOL‐F (Rho = −0.305, P < .001). SQOL‐F was consistently lower among those with high symptom burden across nearly all items; only partner communication showed no difference. Each one‐point increase in DI predicted a 0.61‐point decrease in SQOL‐F ( B = −0.609, P < .001). High‐burden patients also reported significantly lower SF‐36 Physical (PCS) and Mental (MCS) Component Scores. Conclusions Greater airway symptom burden in iSGS is associated with significantly diminished sexual and general health‐related quality of life. These findings reinforce a need for patient‐centered care that considers both physical and psychosocial well‐being.

Abstract Objective Rituximab causes B‐cell depletion and hypogammaglobulinemia, increasing risk for infections. This study aims to determine the incidence of chronic rhinosinusitis (CRS) in patients following rituximab therapy. Study Design Retrospective cohort study using chart review of patients prescribed rituximab between January 2019 and January 2025. Setting Multisite study across Mayo Clinic Enterprise locations in Arizona, Florida, Minnesota, and Wisconsin. Methods Patients with documented rituximab use were included; those with pre‐existing CRS were excluded. Demographic and clinical data—including timing and duration of rituximab therapy, CRS diagnosis, comorbidities (asthma, allergic rhinitis, GERD), and need for sinus surgery—were collected. Descriptive statistics summarized patient characteristics. Group comparisons were performed using t ‐tests, Mann‐Whitney U , and chi‐square tests. Analyses were conducted using SPSS v28. Results Among 17,851 patients prescribed rituximab (median age 64.0 years, M:F ratio 1.1:1), 1105 (6.2%) developed CRS, with an annual incidence of 1.03% (1032 cases per 100,000 person‐years). The median duration of rituximab therapy for those diagnosed with CRS was 5.9 months (IQR, 0.5‐42.6). Most CRS cases occurred after rituximab discontinuation (62.7%, n = 693) compared to during active treatment (37.3%, n = 412). The median delay between rituximab discontinuation and CRS diagnosis was 17.0 months (IQR, 4.3‐41.7). Conclusions This study demonstrates an annual incidence of 1.03% for CRS diagnoses following rituximab. While prior studies report varying CRS incidences in the general population (0.25%‐0.73%), our findings suggest increased risk among rituximab users. Most CRS diagnoses occurred after rituximab discontinuation, emphasizing the need for a comprehensive medication history review during CRS evaluation.

ABSTRACT Airway perforation is a potentially lethal complication from tracheal or mediastinal malignancies that require complex management. Advanced thyroid cancer is known to have high morbidity, and patients with tracheal metastatic lesions are vulnerable to injury. Therapeutic management typically comprises a combination of surgical and nonoperative treatment modalities, whose adverse effects can lead to significant airway injury. We present the case of a 67‐year‐old man with papillary thyroid carcinoma who developed a tracheocutaneous fistula following proton beam therapy and chemotherapy for metastatic disease. Airway repair and recanalization were successfully achieved through a combined surgical and bronchoscopic approach.

Abstract Objective To evaluate whether postoperative intracranial pressure–lowering interventions reduce recurrence of lateral skull base spontaneous cerebrospinal fluid leaks after surgical repair. Data Sources Ovid MEDLINE, Embase, Cochrane CENTRAL, Web of Science Core Collection, and Scopus were searched from inception through April 7, 2025. Review Methods The review followed the Preferred Reporting Items for Systematic Reviews and Meta‐Analyses guidelines and included studies of adults with lateral skull base spontaneous cerebrospinal fluid leaks undergoing primary repair where postoperative intracranial pressure–lowering interventions were specified. Pooled recurrence rates were calculated by intervention type and compared with cohorts that did not receive intracranial pressure–lowering therapy. Results Thirty‐six studies including 687 patients (737 cases) met inclusion criteria. Six comparative cohorts (34 treated, 155 untreated) showed no significant difference in recurrence (risk ratio 1.16, 95% confidence interval [CI]: 0.14–9.76; I 2 = 0%). Across 82 intervention‐only cases, recurrence occurred in three (pooled proportion 0.10, 95% CI: 0.04–0.26; I 2 = 0%). Among 650 control‐only cases, 45 recurred (pooled proportion 0.09, 95% CI: 0.07–0.12; I 2 = 0%). No heterogeneity was observed across pooled analyses. Conclusion Available evidence does not support universal postoperative intracranial pressure–lowering therapy after lateral skull base spontaneous cerebrospinal fluid leak repair. Limited observational data suggest acetazolamide may be associated with lower recurrence, whereas lumbar drainage has not demonstrated sustained benefit. Given the heterogeneity in patient selection and intervention practices, postoperative management should be individualized. Future prospective studies are needed to better define the role of targeted therapy in high‐risk patients.

Abstract Objective To examine the impact of immunosuppressive regimens on chronic rhinosinusitis (CRS) development in kidney and liver transplant recipients. Study Design Retrospective cohort study. Setting Multisite study across Mayo Clinic Enterprise locations in Arizona, Florida, Minnesota, and Wisconsin. Methods Patients who underwent kidney or liver transplantation between November 1, 2021, and November 1, 2022, were included. Patients with documented sinonasal complaints before transplantation were excluded. Diagnoses were based on ICD‐10 codes assigned by board‐certified otolaryngologists, with follow‐up extending through November 2024. Demographic data, relevant comorbidities, CRS diagnoses, and immunosuppressive regimens were collected. Results In total, 1459 transplant recipients (986 kidney, 473 liver) with a mean age of 55.1 years and M:F ratio of 1.5:1 were included. Kidney recipients who received anti‐thymocyte globulin (ATG, Thymoglobulin®) for immunosuppressive induction had a greater risk of CRS compared to those who did not (odds ratio [OR] = 3.0, 95% CI [1.3, 6.9], P = .005). Among liver recipients, patients on cyclosporine, mycophenolate mofetil (MMF), and corticosteroids had a greater risk of CRS compared to those on tacrolimus‐based regimens (OR = 6.0, 95% CI [1.5, 24.1], P = .027). Cyclosporine use was also associated with an increased rate of endoscopic sinus surgery (ESS) compared to tacrolimus (4.2% vs 0.3%, P = .015). Conclusion Tacrolimus‐based regimens are associated with significantly decreased rates of CRS compared to cyclosporine, suggesting that immunosuppressive choice is a modifiable risk factor for sinonasal morbidity in this population.

Abstract Objective To estimate the incidence of de novo chronic rhinosinusitis and identify associated risk factors in kidney and liver transplant recipients without pre‐existing sinonasal complaints. Study design Retrospective cohort study. Setting Multisite study across Mayo Clinic Enterprise locations in Arizona, Florida, Minnesota, and Wisconsin. Methods Records of all patients who underwent kidney or liver transplantation between November 1, 2021, and November 1, 2022 were reviewed. Patients with documented sinonasal complaints prior to transplantation were excluded. Diagnoses were based on ICD‐10 codes assigned by board‐certified otolaryngologists, with follow‐up extending through November 2024. Demographic and clinical variables were collected, and multivariable logistic regression was used to identify predictors of de novo chronic rhinosinusitis. Results Among 1459 transplant recipients (mean age 55.1 years, 59.8% male), the cumulative 2‐year incidence of de novo chronic rhinosinusitis was 2.4% (24/986) in kidney and 2.3% (11/473) in liver transplant recipients ( P = .89). The overall incidence rate was 12.0 cases per 1000 person‐years, exceeding general population estimates. Transplant rejection (OR 3.2, 95% CI 2.5‐3.9, P < .001) and additional organ transplantation (OR 5.0, 95% CI 3.4‐6.5, P = .041) were independently associated with chronic rhinosinusitis development. Conclusion Kidney and liver transplant recipients experience a higher incidence of de novo chronic rhinosinusitis compared to the general population. Transplant rejection and additional organ transplantation significantly increase this risk. Early recognition and management of chronic rhinosinusitis in this population may support improved postoperative outcomes.
