Normal Values of High-Resolution Manometry in Supine and Upright Positions in a Thai Population.

Background: Although cut-off values used in high-resolution manometry (HRM) to diagnose esophageal motility disorders are based on representative samples of the US population and assume a supine position, differences in population and body positioning can reportedly affect results.

Aims: To establish normal HRM values for Thai people in both supine and upright positions.

Methods: Forty-one healthy subjects were recruited, each of whom underwent solid-state HRM with ten 5-mL swallows of water in both the supine and upright positions.

The study of allergic skin test in patients with globus pharyngeus: a preliminary report.

Background: Globus pharyngeus is the lump sensation in the throat associated with various conditions including somatoform disorder and gastroesophageal reflux disease. However, many patients with unrelated causes were found to respond to anti-allergic treatment.

Objective: Determine the results of allergic skin test in globus pharyngeus patients who had unidentified causes.
