OBJECTIVE Non-erosive reflux disease (NERD) constitutes the majority of patients with gastroesophageal reflux disease (GERD). Esophageal pH monitoring is useful in distinguishing patients with NERD from functional heartburn. The gastroenterologist often faces the dilemma of choosing the most appropriate investigative modality. The wireless Bravo capsule(More)
BACKGROUND AND AIM Clarithromycin-based triple therapy (TT) is the first-line treatment for Helicobacter pylori infection in Singapore. There is awareness that TT may no longer be effective due to increased clarithromycin resistance rates. Sequential therapy (ST) and concomitant therapy (CT) are alternative treatment regimens. This study aimed to compare(More)
OBJECTIVE Narrow band imaging (NBI) and NBI-magnifying endoscopy (ME) have been reported to facilitate the diagnosis of intestinal metaplasia (IM) and early gastric cancer (EGC) in high-risk populations. This study aimed at comparing the detection rate of focal gastric lesions by NBI against white light endoscopy (WLE), and examined the utility of NBI-ME in(More)
OBJECTIVE Cough and laryngo-pharyngeal symptoms (LPS) are associated with gastroesophageal reflux disease (GERD). The role of acid reflux (AR) and non-acid reflux (NAR) in atypical GERD pathogenesis is controversial. The aims of the study were to determine the prevalence of high esophageal acid exposure time (AET) in patients presenting with cough or LPS(More)
Acute pancreatitis can present as a mild or severe disease. Most patients have a mild disease and recover without requiring nutritional support. Patients with severe acute pancreatitis may develop systemic inflammatory response syndrome and progress to multi-organ failure. These ill patients have high metabolism and protein catabolism. Hence, the(More)
OBJECTIVE Narrow band imaging (NBI) is generally considered to be useful for lesion characterization, but not enhanced detection of gastric lesions, because of the dark endoscopic view. We tested whether the new generation of NBI (190-NBI or 290-NBI), which is twice as bright as the previous version, would improve detection of premalignant gastric lesions(More)

Rhabdomyolysis is a serious and life-threatening condition in which skeletal muscle is damaged, commonly resulting in acute renal failure. The causes of this clinical entity can be traumatic and non-traumatic. In the latter group, alcohol is the commonest cause. This report describes the case of a 25 year old man who presented with rhabdomyolysis leading to(More)
AIM To evaluate the efficacy of 5 mL simethicone solution in decreasing gastric foam if given at least 30 min before gastroscopy. METHODS This was a randomized, placebo controlled, endoscopist blinded study performed at Changi General Hospital. Patients were at least 21 years old, had no prior surgical resection of the upper gastrointestinal tract, and(More)
