A double blind comparative study comparing Mucaine, Mucaine without oxethazaine, and placebo was carried out with 50 patients with symptoms of heartburn during late pregnancy. We found that the 2 active treatments were more effective than placebo for the relief of heartburn, but there was no statistically significant difference between groups for the relief of nausea and regurgitation. There was a significant difference in the percentage of days of use of each medication, with the placebo being used least frequently. Although not statistically significant, for the 3 measures for which placebo differed from the active treatments, patients showed a better response to mucaine. This suggests that the addition of oxethazaine may be of benefit. The lack of statistical significance may be due to the relatively small number of cases, and the findings are promising. No side effects were recorded for any treatment.

The eagerly anticipated second edition of this popular textbook has finally arrived, with copious updates and additional insights based on Dr. Yarnell's extensive clinical practice, teaching experiences, and delineation of advances in medical research over the past ten years. Students of any medical orientation studying gastroenterology for the first time will find this new edition gives them a superior advantage in approaching this complicated system. The comprehensive material provided for each area gives the reader an in-depth understanding of how the gastrointestinal system works and how to approach its many complexities and pathologies from a holistic and integrated perspective.
Practitioners looking for rapid review, quick reminders, or new tips also find much that benefits them in Natural Approach to Gastroenterology 2nd edition. Natural and conventional information are included. Its ease of use, strong organization, clear writing, clinical usefulness, and many research references will provide the busy clinician with an invaluable resource. Rich in diagrams, algorithms, tables, and extensively indexed for rapid access of material, the book is appropriate in the clinic or the classroom.

Chewed calcium carbonate (CaCO3) rapidly neutralizes esophageal acid and may prevent reflux, suggesting another mechanism of action independent of acid neutralization. Calcium is essential for muscle tone. Our aim was to determine if luminal calcium released from chewed antacids improved esophageal motor function in heartburn sufferers. Esophageal manometry and acid clearance (swallows and time to raise esophageal pH to 5 after a 15-ml 0.1 N HCl bolus) were performed in 18 heartburn sufferers before and after chewing two Tums EX (1500 mg CaCO3, 600 mg calcium). Subjects with hypertensive esophageal contractions or hypertensive lower esophageal sphincter pressure (LESP) were excluded. Subjects with normal to low LESP were included. Differences between parameters were determined by two-tailed paired t-tests, P &3 (47.18 vs 52.97 mm Hg; P = 0.02), distal onset velocity was significantly decreased after CaCO3 (4.34 vs 3.71 cm/sec; P = 0.02), and acid clearance was significantly increased 30 min after CaCO3 (20.35 vs 11.7 swallows, [P &P &LESP was not altered after CaCO3 (22.70 vs 23.79 mm Hg; P = 0.551), however, LESP increased in 9 of 18 subjects. Depth of LES relaxation, medial and distal esophageal contractile amplitude, and duration of contractions were not altered by CaCO3. CaCO3 did not alter salivary secretion and pH in a subset of these subjects, and CaCO3 with secreted saliva did not neutralize a 15-ml acid bolus. The Ca2+ released after chewing of CaCO3 antacids may be partially responsible for the reduction of heartburn by significantly improving initiation of peristalsis and acid clearance.

Background A trial of empirical PPI therapy is usual practice for most patients with symptoms of gastro-oesophageal reflux disease (GERD) in primary care.Aim To determine if the 4-week efficacy of rabeprazole 20 mg for resolving heartburn and regurgitation symptoms is non-inferior to esomeprazole 40 mg or 20 mg.Methods In all, 1392 patients were randomized to rabeprazole 20 mg, esomeprazole 20 mg or 40 mg once daily. Patients, doctors and assessors were blinded. Symptom resolution data were collected on days 0–7 and day-28 using the Patient Assessment of Upper Gastrointestinal Disorders Symptom Severity Index with a shortened version used on days 8–27.Results Rabeprazole 20 mg was non-inferior to esomeprazole 40 mg for complete resolution of regurgitation and satisfactory resolution of heartburn and regurgitation. For complete heartburn resolution, the efficacy of rabeprazole 20 mg and esomeprazole 40 mg was statistically indistinguishable, although the non-inferiority test was inconclusive. Rabeprazole 20 mg was non-inferior to esomeprazole 20 mg for all outcomes.Conclusions In uninvestigated GERD patients, rabeprazole 20 mg was non-inferior to esomeprazole 40 mg for complete and satisfactory relief of regurgitation and satisfactory relief of heartburn, and not different for complete resolution of heartburn.

Folk medicine is a rich source of useful therapeutic tools. Nevertheless, use of medicinal plants can have unwanted, negative effects. By means of the description of an adverse reaction to a herbal remedy, we highlight the need for better efficacy-toxicity studies on these products.To report a case of possible Chelidonium majus L. (Greater celandine)-induced hepatitis and evaluate the past published cases.We outlined the main features of hepatitis associated with use of Chelidonium majus by providing a review of cases reported and analysing in detail a new one.Several cases of acute hepatitis related to Greater celandine consumption were found in the literature. The assessment for causality using Naranjo probability scale showed a probable relationship between the liver injury and the consumption of Chelidonium majus in the case we described.Our case, along with the other ones reported in the literature, increases the concern about the safety of oral use of Chelidonium majus. Plants used in traditional medicine are not necessarily harmless. Customers and prescribers should be aware of this, especially when a herbal drug is used with therapeutic purposes in absence of reliable studies of clinical efficacy and benefit-risk assessment.

Non-erosive reflux disease and erosive esophagitis are the most common phenotypic presentations of gastroesophageal reflux disease. Recent reports suggest that patients with non-erosive reflux disease treated with antireflux medications show lower symptom improvement rates than patients with erosive esophagitis treated with the same medications. The aim was to assess the acid reflux and symptom patterns of patients with non-erosive reflux disease in comparison with those with erosive esophagitis and to identify different non-erosive reflux disease subgroups. One hundred and twenty consecutive patients (67 male, age: 37.6±12.9 years) seen for classic heartburn symptoms were evaluated for the study. The patients underwent upper endoscopy and 24-hour ambulatory pH monitoring. Erosive esophagitis was identified in 51 patients and nonerosive reflux disease in 69 patients. According to pH metric findings (DeMeester Score >14.72 or Fraction Time >4%), 31.9% of the non-erosive reflux ...

Dyspepsia itself is not a diagnosis but stands for a constellation of symptoms referable to the upper gastrointestinal tract. It consists of a variable combination of symptoms including abdominal pain or discomfort, postprandial fullness, abdominal bloating, early satiety, nausea, vomiting, heartburn and acid regurgitation. Patients with heartburn and acid regurgitation invariably have gastroesophageal reflux disease and should be distinguished from those with dyspepsia. There is a substantial group of patients who do not have a definite structural or biochemical cause for their symptoms and are considered to be suffering from functional dyspepsia (FD). Gastrointestinal motor abnormalities, altered visceral sensation, dysfunctional central nervous system-enteral nervous system (CNS-ENS) integration and psychosocial factors have all being identified as important pathophysiological correlates. It can be considered as a biopsychosocial disorder with dysregulation of the brain-gut axis ...
