Patient-centred outcome measures such as the Short Form-36 (SF-36) have been developed to assess the impact of ill health and medical interventions on self-reported health status. The objective of the study was to assess the impact of gastrointestinal disease upon health status as measured by the SF-36 physical and mental health component scores (PCS and MCS) and to assess whether these component scores might be an appropriate outcome measure for use in clinical research in gastroenterology. The subjects were 364 patients aged between 18 and 64 years who had been prescribed proton pump inhibitors (PPIs) by general practitioners in Oxfordshire. The general practices participating identified patients who had been prescribed PPIs. The data were abstracted from the general practice medical records of these patients concerning gastrointestinal diagnoses and other prescribed medications. The patients were sent the SF-36 questionnaire by post and the PCS and MCS scores were derived, which were adjusted for age and sex and compared with the scores of the general population of the Oxford region. Co-morbidity was assessed by the extent to which non-gastric medications were also used. The commonest diagnoses were oesophagitis/gastro-oesophageal reflux and indigestion. People with these diagnoses had significantly lower health status than the general population. Differences persisted when the results were controlled for the possible effects of co-morbidity. It was concluded that the SF-36 is sensitive to the impact of gastrointestinal disease on health status.

Dyspepsia is most optimally defined as pain or discomfort centred in the upper abdomen. The symptom complex may be caused by peptic ulcer disease, gastro-oesophageal reflux, or gastric cancer but is most often due to functional (or non-ulcer) dyspepsia. While upper endoscopy is the method of choice to determine the underlying cause of dyspepsia, it is expensive. A more pragmatic approach is needed in the Asia Pacific region where health services are limited. A detailed treatment algorithm is given for managing patients presenting with new-onset dyspepsia and documented functional dyspepsia after endoscopy, and evidence to support this approach is reviewed. Prompt endoscopy is recommended for patients with alarm features. In patients without alarm features, treatment for 2-4 weeks with an empirical anti-secretory or prokinetic agent, followed by investigation using non-invasive Helicobacter pylori testing and treatment for patients who do not respond or relapse, is recommended. Trials of management strategies are now needed to establish the efficacy and cost-effectiveness of the approaches recommended.

Dyspepsia is a major public problem. It occurs in 25-40% of the general population negatively affecting the quality of life. 2-3% of the patients visited by the GP and up to 30% of those visited by the gastroenterologist have dyspepsia. Both diagnostic procedure and therapy are expensive. Definition, aetiology and pathogenesis of the disorder are not clear cut. The aim of this review is to outline the main trends in the relevant area of the clinical practice. The authors choose the most comprehensive definition among the thirty of the medical literature. To rule out, the most commonly and frequently wrong opinions risk factors have been examined. The authors distinguished between symptoms of function and organic dyspepsia and those of Irritable Bowel Syndrome and Gastro-Esophageal Reflux Disease, which often overlap and make difficult the management of the patient. The aetiology and pathogenesis have also been discussed, with particular emphasis on Hp. Advantages and drawbacks of different diagnostic approaches have been investigated. An age and symptoms related approach of the cases with dyspepsia is proposed, which allows to manage the patient without the necessity of invasive procedures. It is finally suggested that are cases which can be managed by the GP and others for whom the gastroenterologist intervention is mandatory.

We have audited the first 3 yr of a new open access gastroscopy service in the Royal Victoria Hospital, Belfast to assess service demands, patient demography and diagnostic trends. Over 3 yr there were 1872 referrals (800 from fundholding general practitioners), 8.8 per cent were non attenders and 5.4 per cent cancelled appointments. Endoscopic diagnostic categories showed no significant change over the 3 yr, 39 per cent non ulcer dyspepsia, 35 per cent gastro-oesophageal reflux disease (GORD), 17 per cent peptic ulcer disease (PUD), 6 per cent GORD and PUD, 1 per cent gastric erosions and 0.8 per cent carcinoma.

Patients with gastroparesis frequently present challenging clinical, diagnostic, and therapeutic problems. Data from 146 gastroparesis patients seen over six years were analyzed. Patients were evaluated at the time of initial diagnosis and at the most recent follow-up in terms of gastric emptying and gastrointestinal symptomatology. The psychological status and physical and sexual abuse history in female idiopathic gastroparesis patients were ascertained and an association between those factors and gastrointestinal symptomatology was sought. Eighty-two percent of patients were females (mean age: 45 years old). The mean age for onset of gastroparesis was 33.7 years. The etiologies in 146 patients are: 36% idiopathic, 29% diabetic, 13% postgastric surgery, 7.5% Parkinson's disease, 4.8% collagen vascular disorders, 4.1% intestinal pseudoobstruction, and 6% miscellaneous causes. Subgroups were identified within the idiopathic group: 12 patients (23%) had a presentation consistent with a viral etiology, 48% had very prominent abdominal pain. Other subgroups were gastroesophageal reflux disease and nonulcer dyspepsia (19%), depression (23%), and onset of symptoms immediately after cholecystectomy (8%). Sixty-two percent of women with idiopathic gastroparesis reported a history of physical or sexual abuse, and physical abuse was significantly associated with abdominal pain, somatization, depression, and lifetime surgeries. At the end of the follow-up period, 74% required continuous prokinetic therapy, 22% were able to stop prokinetics, 5% had undergone gastrectomy, 6.2% went onto gastric electrical stimulation (pacing), and 7% had died. At some point 21% had required nutrition support with a feeding jejunostomy tube or periods of parenteral nutrition. A good response to pharmacological agents can be expected in the viral and dyspeptic subgroups of idiopathics, Parkinson's disease, and the majority of diabetics, whereas a poorer outcome to prokinetics can be expected in postgastrectomy patients, those with connective tissue disease, a subgroup of diabetics, and the subset of idiopathic gastroparesis dominated by abdominal pain and history of physical and sexual abuse. Appreciation of the different etiologies and psychological status of the patients may help predict response to prokinetic therapy.

This paper provides a comprehensive review of the current knowledge on cisapride in different clinical conditions in children: different manifestations of gastro-oesophageal reflux, such as (excessive) regurgitation, oesophagitis, chronic respiratory disease or uncontrolled asthma, cystic fibrosis, chronic dyspepsia, constipation and pseudo-obstruction, and as an aid to small bowel capsule-biopsy. It discusses, in depth, the safety profile of cisapride in paediatric patients.

Helicobacter pylori gastritis (i.e. H. pylori infection and complications) is a focus of tremendous research activity today. Besides peptic ulcer disease, a large number of reports suggest that other diseases are associated with H. pylori. The International Agency for Research on Cancer sponsored by the World Health organization classified the bacterium as a group I carcinogen in 1994. Population-based studies of H. pylori and gastric cancer in 1991 showed an increased odds ratio, of 3-6, in infected patients, and a calculation of odds ratios in different age groups showed a markedly increased odds ratio, to about 20, in younger ages. Studies of non-ulcer dyspepsia and the effect of cure of H. pylori show either none, small, or significant symptom relief, suggesting a positive effect in a subgroup of non-ulcer dyspepsia patients. Mucosa-associated lymphoid tissue-lymphoma caused by H. pylori could be eradicated, at least in its mild forms. Barrett's ulcer is a possible H. pylori-associated disease as well as gastroesophageal reflux disease. Normal feedback in the acid regulation system is changed in infected patients, which may facilitate an increased gastroesophageal acidic reflux. Gastropathy and/or peptic ulcer due to use of nonsteroidal antiinflammatory drugs is probably aggravated by the infection. The infectious disease H. pylori gastritis is associated with a large number of complications, some of which are serious. There are no data showing any advantages of the infection. Giving anti-H. pylori therapy to infected patients should be regarded as essential.

Gastro-oesophageal reflux disease is the most common cause of indigestion in the community, and is usually chronic. Typical symptoms are recurrent retrosternal burning (heartburn) and regurgitation of sour or bitter fluid. In patients with typical symptoms and no alarm symptoms (pain on swallowing, dysphagia, weight loss or anaemia), treatment may be instituted without investigation. Patients with alarm symptoms and those who respond poorly or relapse after initial treatment require investigation (endoscopy and possibly pH monitoring). About 60% of reflux sufferers have no evidence of mucosal injury; their management aims to relieve symptoms. About 40% of reflux sufferers have oesophagitis and/or complications such as Barrett's oesophagus or oesophageal stricture at endoscopy. Drug therapy consists of H2-receptor antagonists, cisapride or proton-pump inhibitors.

There is international agreement that dyspepsia refers to pain or discomfort centered in the upper abdomen. However, the term 'discomfort' has been variably defined. While other symptoms may often be simultaneously present, gastro-oesophageal reflux disease can usually be clearly distinguished by the presence of predominant heartburn. Dyspepsia is a frequent reason for consultation in primary care and in gastrointestinal practice. With the widespread availability and utilization of endoscopy, it has become evident that a structural (or organic) explanation is found in only a minority of patients presenting with dyspepsia. Operationally, functional dyspepsia is defined as persistent or recurrent dyspepsia for 3 or more months in the absence of a clinically identifiable structural disease causing the symptoms. It has been proposed, based on symptoms, that functional dyspepsia be subdivided into symptom subgroups to promote patient homogeneity. The initially proposed 'clustering' of symptoms into ulcer-like and dysmotility-like functional dyspepsia has proved a dismal failure because of the considerable overlap observed, the lack of stability over time and the failure to identify robust pathophysiological abnormalities or responses to therapy. A subcategorization based upon the most bothersome symptom is theoretically more attractive but needs to be prospectively and rigorously tested.

Functional dyspepsia is a chronic disorder of unknown aetiology. The lack of endoscopic abnormalities in patients with this disorder has led many physicians to believe that gastro-oesophageal reflux disease may be responsible for most symptoms. Our group has addressed this issue, by pathophysiological studies in a large cohort of Dundee patients with persistent dyspeptic symptoms. Peptic ulcer and gallstones were excluded in all patients by appropriate tests. Ambulatory pH monitoring showed oesophageal acid reflux that lay above the conventional diagnostic threshold in approximately 20% of patients. This subset was diagnosed as having gastro-oesophageal reflux disease. In the remainder, moderate or severe reflux-like symptoms were reported by approximately 44% patients, who were categorized as reflux-like functional dyspepsia. Reflux symptoms were mild or absent in 36% patients, who were categorized as non-reflux-like dyspepsia. While oesophageal pH profiles lay within the conventional normal range in both of these functional dyspepsia subgroups, patients with reflux-like functional dyspepsia had significantly greater acid exposure values, including total oesophageal acid exposure time, percentage time at a pH of less than 4.0, DeMeester scores and pain reflux event correlation. Hence patients with reflux-like functional dyspepsia have oesophageal acid exposure that lies below the diagnostic threshold for gastro-oesophageal reflux disease but exceeds that of patients with non-reflux dyspepsia. The high pain/reflux event correlation in reflux-like functional dyspepsia suggests that subthreshold oesophageal acid exposure may be associated with troublesome reflux symptoms.
