Endoscopic ultrasound navigated application of botulinum toxin in severe esophageal motility disorder.

The use of botulinum toxin in the therapy of esophageal motility disorders is reserved for elderly and comorbid patients considered risky for endoscopic or surgical treatment. However, there is a lack of data on the treatment of motility disorders outside the Chicago classification.We present the case of a 56-year-old patient with dysphagia and non-cardial chest pain (Eckardt 8).

Esophageal Infusion of Menthol Does Not Affect Esophageal Motility in Patients with Gastroesophageal Reflux Disease.

Menthol is thought to trigger gastroesophageal reflux disease (GERD) symptoms by influencing esophageal peristalsis and lower esophageal sphincter (LES) function. We evaluated the effect of esophageal menthol infusion on esophageal motility and the LES in healthy volunteers and in patients with GERD. High resolution manometry (HRM) catheter with attached thin tube for menthol infusion was placed transnasally.

Increased Sensitivity of Cough Reflex is Not the Mechanism of Cough Attributed to Laryngopharyngeal Reflux.

Objectives: In laryngopharyngeal reflux (LPR) patients acid reaches laryngopharyngeal area and stimulates/sensitizes respiratory nerve terminals mediating cough. We addressed several hypothesis: if stimulation of respiratory nerves is responsible for coughing then acidic LPR should correlate with coughing and proton pump inhibitor (PPI) treatment should reduce both LPR and coughing. If sensitization of respiratory nerves is responsible for coughing then cough sensitivity should correlate with coughing and PPI should reduce both coughing and cough sensitivity.
