Non-ulcer dyspepsia is a common clinical disorder characterised by reduced gastric motility. Safety concerns have restricted use of currently available prokinetic drugs. Itopride is a new safer prokinetic drug with dopamine D2 antagonism and acetylcholinesterase inhibitory actions. The ENGIP-II study was conducted to investigate the efficacy, and safety of itopride in patients of non-ulcer dyspepsia. There were significant reductions in upper abdominal pain, heartburn frequency, gastro-oesophageal regurgitation, nausea, bloating, early satiety after meals at day 3 only; whereas significant improvements were noted in belching, anorexia at day 6 and in vomiting at day 9. Thus, ENGIP-II study shows that itopride was well tolerated patients and appears to be the drug of choice in patients with non-ulcer dyspepsia.

An age-appropriate questionnaire (GASP-Q) was used to assess the frequency and severity of the gastroesophageal reflux disease (GERD) symptoms: abdominal/belly pain, chest pain/heartburn, pain after eating, nausea, burping/belching, vomiting/regurgitation, choking when eating, and difficulty swallowing, in adolescents age 12 to 16 years. The primary objective was to compare the mean composite symptom score (CSS) at week 8 with baseline after treatment with 20 or 40 mg of pantoprazole. Statistically significant (p < 0.001) improvement in CSS occurred in both groups. Safety was comparable between the 2 groups. Pantoprazole was safe, well tolerated, and effective in reducing symptoms of GERD in adolescents.

Recent studies indicate that impaired meal accommodation or hypersensitivity to distention are highly prevalent in adult functional dyspepsia (FD). Our aim was to investigate whether similar abnormalities also occur in paediatric FD. Sixteen FD patients (15 girls, 10-16 years) were studied. The severity (0-3; 0, absent; 3, severe) of eight dyspeptic symptoms (epigastric pain, fullness, bloating, early satiety, nausea, vomiting, belching and epigastric burning) and the amount of weight loss were determined by questionnaire. All children underwent a gastric barostat study after an overnight fast to determine sensitivity to distention and meal-induced accommodation, which were compared with normal values in young adults (18-22 years). On a separate day, all patients underwent a gastric emptying breath test. A mean weight loss of 4.8 +/- 0.9 kg was present in 14 children. Compared with controls, patients had lower discomfort thresholds to gastric distention (8.8 +/- 1.0 mmHg vs 13.9 +/- 1.9 mmHg, P < 0.02) and gastric accommodation (87 +/- 25 mL vs 154 +/- 20 mL P < 0.04). Hypersensitivity to distention and impaired accommodation were present in respectively nine (56%) and 11 (69%) patients. No relationship was found between barostat and gastric emptying, which was delayed in only three patients. The majority of children with unexplained epigastric symptoms have abnormalities of gastric sensorimotor function.

The cascade stomach consists of a biloculation of the gastric cavity into a ventral (corpus and antrum) and a dorsal (fundus) recess and is a rare cause of upper abdominal symptoms. The causes of gastric cascade described in the literature are manifold and are separated into congenital, functional, or organic disorders. Patients with a gastric cascade can have a range of upper abdominal symptoms, including nausea, vomiting, dyspepsia, eructation, heartburn, epigastric pain, and early satiety. This disorder is often difficult to diagnose or is not recognized and, therefore, its true incidence is currently not known. As a consequence, data on the treatment of the condition are limited. Suggested treatment options in the literature range from conservative measures, such as bending exercises or dietary adjustments, to operative corrections, such as gastropexy and laparoscopic gastro-gastric anastomosis. In this paper, we summarize the literature findings on gastric cascade and report on a new treatment option: the laparoscopic gastric sleeve resection.

Although high-degree atrioventricular (AV) block in patients with a history of syncope usually requires pacemaker implantation, therapeutic strategies should also be considered. A 35-year-old man presented with complaints of palpitations, nausea and dysgeusia. Since aged 30, the patient had experienced three episodes of syncope. Holter monitoring showed transient high-degree AV block (up to 5:4 block) associated with nausea, eructation and dysgeusia irrelevant to posture as well as ventricular ectopic beats with palpitation. A head-up tilt test revealed neurally mediated vasodepression but electrophysiological study showed no abnormalities. These results indicated that his transient high-degree AV block was functional, and syncope would have been because of neurally mediated vasodepression, not bradycardia. After administration of disopyramide at 300 mg daily, the symptoms subsided and ventricular ectopic beats and AV block disappeared. He has been well for 20 months.

Non ulcer dyspepsia is one of the most common problems encountered in primary care practice. The underlying pathophysiology of non ulcer dyspepsia is not fully understood, but it is known that this condition is associated with H. pylori infection and motility disorder. The presenting abdominal symptoms are non specific: they include bloating, belching, flatulence, excessive fullness after eating and nausea. Psychological condition such as anxiety, depression and stress do play a role in the recurrence of symptoms. Upper GI endoscopy is necessary in patients who presents with alarm symptoms suggestive of possible underlying organic condition before one makes the diagnosis of non ulcer dyspepsia. Pharmacological therapy using H2 receptor antagonist and proton pump inhibitors are effective for symptom relief. Patient's education and supportive care should be part of the management strategy in recurrent chronic dyspepsia.

In patients with gastrointestinal symptoms, weight loss is an alarm symptom, indicative of organic disease. Recent studies reported weight loss in subsets of functional dyspepsia (FD) patients. The aim of this study was to analyse symptom patterns associated with weight loss in tertiary care FD. Six hundred and thirty-six FD patients (67% female, mean age 43 years) completed a dyspepsia questionnaire, and underwent gastric emptying and gastric barostat studies. After identifying independent symptom domains through orthogonal factor analysis, patients were clustered on the basis of symptom profile. Clusters were compared in terms of their association with weight loss and gastric emptying or sensorimotor function. Weight loss (4.2 kg on average) correlated most strongly with early satiety followed by nausea and vomiting (rho respectively 0.38, 0.28 and 0.23, all P < 0.0001). Factor analysis revealed three factors: Factor 1 characterized by nausea, vomiting and early satiety; factor 2 by early satiety, postprandial fullness and bloating; and factor 3 by pain, epigastric burning and belching. Subsequent cluster analysis revealed six patient clusters. The most severe cluster, which loaded high on all three factors, and a cluster dominated factor 2 were associated with the highest average weight loss (6.8 and 8.0 kg, respectively). The former cluster was also characterized by visceral hypersensitivity and delayed gastric emptying. The lowest weight loss occurred in the two clusters that had depressed scores for both early satiety associated factors (2.4 and 2.5 kg, respectively). In tertiary care FD, weight loss is strongly associated with two early satiety associated symptom clusters.

Rabeprazole is a proton pump inhibitor that can be used in the treatment of acid-peptic-related disorders (gastroesophageal reflux disease [GERD], duodenal ulcer, gastric ulcer, gastric acid hypersecretory syndromes) and Helicobacter pylori. Pharmacodynamic data has demonstrated that rabeprazole, with a high pKa of approximately 5.0, can be activated at a higher pH than other proton pump inhibitors. This possibly results in faster onset of action. Owing to its non-enzymatic pathway of metabolism, rabeprazole is also less influenced by genetic polymorphisms of the CYP2C19, which others proton pump inhibitors are dependent on. In a 2-week, placebo-controlled trial, rabeprazole was both rapid and effective in relieving heartburn on day 1 of therapy and improved other GERD-related symptoms including regurgitation, belching, bloating, early satiety and nausea. For oesophageal reflux disease without erosions both 10 and 20 mg of rabeprazole are equivalent and better than placebo at 2 and 4 weeks. An on-demand approach to non-erosive reflux disease with 10 mg of rabeprazole has also been documented as superior to placebo. Some success in the treatment of extra-oesophageal manifestations of GERD, such as asthma and chronic laryngitis, has also been achieved with rabeprazole. Overall, rabeprazole with very few side effects is a safe and efficacious medication for acid suppression therapy.

The pathophysiology of functional dyspepsia (FD) is unknown and several mechanisms associated with specific symptom patterns have been recently proposed. Increased duodenal acid exposure has been supposed to be associated with nausea, but recently an increase of severity of several dyspeptic symptoms was noted in a subset of dyspeptic patients. As its pathogenetic role is still unclear, we evaluated an involvement of duodenal acid exposure in symptom generation by inducing a hyperacidity status of the duodenum. Twelve young adult healthy volunteers in a randomized, double-blind protocol, underwent duodenal acid (0.2 N, 5 mL min(-1)) or saline perfusion, antropyloroduodenal manometry and duodenal pH monitoring both during fasting and postprandially. Every 15 min, severity of discomfort, fullness, bloating, belching, nausea, heartburn, epigastric burning, satiety and pain were evaluated by visual analogue scale. During acid perfusion, symptom scores for discomfort, bloating, nausea, epigastric burning were significantly higher (P < 0.01) compared to saline. Postprandial antral motility index was lower (2.96 +/- 1.8 vs 3.62 +/- 1.8, P = 0.01) and jejunal motility index higher (4.87 +/- 1.0 vs 4.37 +/- 1.4, P = 0.01) during acid perfusion. Occurrence and duration of phases III of the migrating motor complex showed no difference. Duodenal acid perfusion causes a sensitization to dyspeptic symptoms and induces antral hypomotility and jejunal hypercontractility. Through these mechanisms, increased duodenal acid exposure may play a role in the pathophysiology of FD symptoms.

Gastrocolic fistula secondary to primary gastric lymphoma is a very rare entity. On admission to outpatient clinics, it may be difficult to diagnose gastrocolic fistula, as its clinical symptoms are nonspecific. A 65-year-old man was presented with weight loss, nausea, vomiting, diarrhea, fatigue, foul-smelling eructation, and upper abdominal pain for the last 2 months. He had also been started antituberculosis drugs 2 months ago because of acid-resistant bacillus (ARB) positivity in sputum in a state hospital. Therefore, symptoms such as nausea and vomiting were attributed to the drugs used for tuberculosis. However, nausea and vomiting continued despite stopping the drugs. Upper endoscopical examination revealed a large crater on the posterior wall of gastric corpus. A large fistulous opening to the transverse colon was also identified during endoscopic examination. An upper gastrointestinal x-ray series demonstrated a fistula between the stomach and the transverse colon. Histopathological examination of the gastric biopsy was determined to be primary gastric diffuse large B-cell-type non-Hodgkin's lymphoma. In conclusion, persistent vomiting may suggest a probable gastrocolic fistula despite nonspecific clinical findings. In the literature, the present case represents the first report of a gastrocolic fistula due to gastric lymphoma in a patient with tuberculosis at its initial presentation.
