Thailand Dyspepsia Guidelines: 2018.

The management of dyspepsia in limited-resource areas has not been established. In 2017, key opinion leaders throughout Thailand gathered to review and evaluate the current clinical evidence regarding dyspepsia and to develop consensus statements, rationales, levels of evidence, and grades of recommendation for dyspepsia management in daily clinical practice based on the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) approach. This guideline is mainly focused on the following 4 topics: (1) evaluation of patients with dyspepsia, (2) management, (3) special issues (overlapping gastroesophageal reflux disease/irritable bowel syndrome and non-steroidal anti-inflammatory drug/aspirin use), and (4) long-term follow-up and management to provide guidance for physicians in Thailand and other limited-resource areas managing such patients.

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.

Normal Solid Gastric Emptying Values Measured by Scintigraphy Using Asian-style Meal:A Multicenter Study in Healthy Volunteers.

Background/aims: To report gastric emptying scintigraphy, normal values should be established for a specific protocol. The aim of this study was to provide normal gastric emptying values and determine factors affecting gastric emptying using Asian rice-based meal in healthy volunteers.

Methods: One hundred and ninety-two healthy volunteers were included at 7 tertiary care centers across Thailand.

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.

Vocal cord dysfunction concurrent with a nutcracker esophagus and the role of gastroesophageal reflux disease.

Background: Psychological disorders were originally thought to be the sole cause of vocal cord dysfunction (VCD). Subsequently, other organic diseases, including structural laryngeal abnormalities, have also been reported to be associated with VCD.

Objectives: To describe the first patient with VCD concurrent with a nutcracker esophagus and to establish the association between VCD and gastroesophageal reflux disease (GERD) by using the Bernstein test.
