Objective: The present study aimed to investigate the symptomatic swallowing complaints in individuals with total laryngectomy (TL) and reveal how swallowing kinematics differs between those with and without symptomatic dysphagia complaints.
Methods: A total of 34 subjects with TL were included in the study. Swallowing kinematics of those with symptomatic swallowing complaints (Group 1) were compared to those without (Group 2). Kinematic parameters including pharyngeal transit duration (PTD), maximum pharyngeal constriction ratio (MPCR), upper esophageal sphincter opening ratio (UESOR), upper esophageal sphincter opening duration (UESOD), and bolus clearance ratio (BCR) were investigated from Videofluoroscopic Swallowing Study (VFSS) records via ImageJ software.
Results: Symptomatic swallowing complaints were determined in 47.1% of the subjects (n = 16). Difficulty while swallowing solid foods and pills, diminished pleasure of eating, food getting stuck in the throat, and increased level of stress during swallowing were among the major swallowing complaints in the present cohort. PTD, MPCR, and BCR parameters were significantly higher in subjects with symptomatic swallowing complaints than those without.
Conclusion: These preliminary findings indicate that almost half of individuals with TL may have symptomatic swallowing complaints. The underlying pathophysiology of this phenomenon may be the devianced kinematic parameters including PTD, MPCR, and BCR in this population. Therefore, it is recommended to include the kinematic measurements in the dysphagia evaluation protocol in individuals with TL, most notably in those with symptomatic swallowing complaints.

Eosinophilic esophagitis (EoE) is a chronic allergic condition affecting the esophagus and driven by food antigens. Many individuals diagnosed with EoE have other allergic conditions, such as food allergy, asthma, allergic rhinitis, and atopic dermatitis. The clinical goals of therapy in EoE include symptomatic, histologic, and endoscopic remission.

Introduction: We assessed potential mechanisms behind the requirement for more frequent dupilumab dosing in eosinophilic esophagitis (EoE) compared with other approved indications.
Methods: Results for the phase 3 LIBERTY EoE TREET study co-primary endpoints (proportion of patients achieving a peak intraepithelial eosinophil count of ≤6 eosinophils per high-power field and absolute change from baseline in Dysphagia Symptom Questionnaire total score) were pooled in exposure-response analyses.
Results: A steep initial relationship then plateau was observed between higher dupilumab steady state trough concentrations (Ctrough) and decreased eosinophilic infiltration at Week 24, while a graded exposure-response relationship was observed for symptomatic improvement at Week 24.

Introduction: Complete inability to belch due to retrograde cricopharyngeus dysfunction (R-CPD) may lead to chronic gas-related gastrointestinal complaints. We aimed to validate high-resolution manometric (HRM) diagnostic criteria and prospectively evaluate the feasibility and efficacy of cricopharyngeal botulinum toxin injection (CBTI) by flexible endoscopy.
Methods: Consecutive manometrically diagnosed patients with R-CPD were included.

Background & Aims: Few data compare topical corticosteroid (tCS) dosing regimens and outcomes. We aimed to compare treatment outcomes in patients with eosinophilic esophagitis (EoE) by once or twice daily dosing regimens.
Methods: We conducted a retrospective cohort study using the UNC EoE Clinicopathologic Database of newly diagnosed patients with EoE treated with a tCS who had a follow-up endoscopy with biopsy.
