Dyspepsia may result from over-indulgence in alcohol and food, or from anxiety and emotional problems. It may also indicate a peptic ulcer, oesophagitis or less commonly, gallstones or gastric cancer. Investigation by endoscopy or barium studies is always indicated when an organic lesion is suspected. Reassurance, tranquillizers and antispasmodics help patients with functional dyspepsia. Antacids given hourly between meals are important in the treatment of all symptomatic peptic ulcers. Cimetidine causes rapid symptomatic relief of duodenal ulcer symptoms, and most ulcers will heal with six weeks' therapy. Gastric ulcer can be treated with carbenoxolone, but this drug is avoided in the elderly and in patients with cardiac failure or hypertension. Anticholinergic drugs are of value in duodenal ulcer, especially for night pain, but they should not be used in patients over the age of 50. Special diets are of no value. For the heartburn of oesophagitis, weight reduction and a regime of regular antacid therapy remain the important measures.

It is difficult to ascertain the incidence of gastrointestinal side effects associated with intake of non-steroidal anti-inflammatory drugs (NSAIDs). Serious side effects, such as bleeding, perforation, and heart failure, occur in approximately 1% of patients using NSAIDs. One-third of all patients receiving NSAIDs will have gastrointestinal complaints. Since at least 10% of patients terminate treatment with NSAIDs as a result of side effects, even reduction of those that are not life-threatening would be of great benefit. H2-receptor antagonists have proved effective in ulcer treatment, and their use as prophylaxis against the side effects of NSAIDs is being widely studied. In a recent study, 63 patients who had experienced serious upper gastrointestinal side effects were given cimetidine while continuing their NSAID therapy. All but 4 of 47 who had gastric or duodenal ulcer on first admission were healed at 8 weeks, and none of the remaining 16 with diffuse bleeding gastritis experienced further clinical episodes of bleeding or ulcer-related dyspepsia. Bijlsma has reported a double-blind multicentre study using cimetidine or placebo. When GI symptoms led to endoscopic evaluation, GI symptoms were significantly reduced after cimetidine.

It is difficult to ascertain the incidence of gastrointestinal side-effects associated with intake of non-steroidal anti-inflammatory drugs (NSAIDs). In retrospective studies, some NSAIDs have been reported to be associated with a higher incidence of gastrointestinal side-effects than others. However, this has not been verified either in a prospective case-review study or in a large double-blind study. Serious side-effects, such as bleeding, perforation and heart failure, occur in approximately 1% of patients using NSAIDs. One-third of all patients receiving NSAIDs will have gastrointestinal complaints. Since at least 10% of patients terminate treatment with NSAIDs as a result of side-effects, even reduction of those that are not life-threatening would be of great benefit. H2-receptor antagonists have proved effective in ulcer treatment, and their use as prophylaxis against the side-effects of NSAIDs is being widely studied. In a recent study, 63 patients who had experienced serious upper gastrointestinal side-effects were given cimetidine while continuing their NSAID therapy. All but 4 of the 47 who had gastric or duodenal ulcer on first admission were healed at 8 weeks, and none of the remaining 16 with diffuse bleeding gastritis experienced further clinical episodes of bleeding or ulcer-related dyspepsia.

Benign tumors of the small bowel are rare. They present with many different manifestations depending on the size and location, and also cause a variety of symptoms that are often nonspecific. These include abdominal pain, dyspepsia, nausea, vomiting, and gastrointestinal bleeding that may be melena or hematemesis. Most of the time patients are asymptomatic and the lesions are discovered as an incidental finding. When bleeding occurs, and it may be severe in certain situations, the patient may develop signs of anemia, such as dyspnea, fatigue, and even high-output cardiac failure. The authors present a patient who was evaluated for melena and who was found to have a duodenal polyp that proved to be a Brunner's gland adenoma on pathology.

The influence of renitec and ednit on duodenal ulcer was studied in 25 patients with cardiac failure. It was found that renitec and ednit lowered both systolic and diastolic pressure, relieved gastralgia and dyspepsia. Duodenal ulcer healed in 87% of the patients. Contracting and pump function of the right ventricle improved. Plasma levels of angiotensin and aldosteron decreased while prostaglandin E2 increased.

Erectile dysfunction (ED) in men is amenable to correction with Viagra in a majority of patients. The accumulated experience of prescribing Viagra across the broad continuum of men suffering from ED is sufficient for a meaningful assessment of the safety of Viagra in clinical practice. The use of Viagra necessitates caution in cardiac failure and when used within six months of acute myocardial infarction and stroke. It is inadvisable in patients with unstable angina pectoris. The co-administration of Viagra with organic nitrates, for example, glyceryl trinitrate or isosorbide dinitrate, is unsafe. The relative contraindications to Viagra in cardiovascular disease are uncontrolled hypertension and impaired cardiac reserve. With respect to interactions with other drugs, the potential influence on the metabolism of Viagra by medications that affect the cytochrome-P-450 system does not translate into clinical effects. The vasodilatory properties of sildenafil citrate are largely responsible for unwanted effects. The most common side effects are headache, flushing (due to vasodilation), and dyspepsia (due to relaxation of the smooth muscle of the gastroesophageal sphincter with reflux). In the recommended single-dose range (25-100 mg), the use of Viagra for erectile dysfunction, in the absence of contraindications, is extremely safe provided the drug is taken under proper conditions.

There is now conclusive evidence that most patients with heart failure due to left ventricular systolic dysfunction should be treated with angiotensin converting enzyme (ACE) inhibitors and beta-blockers. They will also need diuretics for the control of fluid retention. There is also a powerful case for adding spironolactone to the treatment of patients with more severe symptoms. Many doctors would also use digoxin and, especially if coronary disease is present, aspirin or warfarin. Most patients also have other chronic diseases, such as diabetes, arthritis, depression and dyspepsia, and each of these may provoke the prescription of yet another agent. Many patients will receive prescriptions to treat the side-effects of their therapy. Finding a sure path through the morass of pharmacotherapy is a daunting task. Polypharmacy is having a negative impact on new drug research in an area where there are in fact remarkably few really effective treatments and the therapeutic problem is only partially solved. This paper discusses some of the issues surrounding polypharmacy in heart failure and how to resolve them, using an illustrative case history. It highlights the potential benefits of polypharmacy with effective drugs and the gross over-use of ineffective treatments in heart failure. The major problem with polypharmacy in heart failure is not the heart failure treatment itself, but the drugs for other concomitant conditions, the effectiveness of which is often not supported by an appropriate evidence base and for which alternative, less noxious management strategies often exist. Polypharmacy may be deleterious not only because of the increased potential for side-effects and drug interactions but also because taking unnecessary therapy reduces compliance with effective drugs.

Primary amyloidosis is a rare disease, cardiac involvement occurs in up to 40% of patients. Diffuse amyloid deposits cause an impairment of myocardial systolic and diastolic function. In this paper we are presenting a case of a 54-year-old woman. The woman was admitted because of progressive fatigue, dyspnoea, chest pain, later she experienced hypotension, dyspepsia, and enterorrhagia. ECG showed decrease in QRS amplitude. We have found an echocardiographic evidence of wall hypertrophy. Right cardiac catheterization showed a restrictive situation. Immunobinding of serum and urine revealed monoclonal kappa light chains. The diagnosis was determined by rectal biopsy. Unfortunately, amyloid deposits caused progressive heart failure, hemorrhage, and death just before the diagnosis of primary amyloidosis could be determined on the basis of results of the immunofixations of serum and urine proteins (detection of the monoclonal light chains kappa) and from biopsy specimens taken from rectum (amyloid deposits).

The objective was to improve understanding of adverse events occurring with celecoxib in the treatment of osteoarthritis and rheumatoid arthritis. Data were extracted from company clinical trial reports of randomised trials of celecoxib in osteoarthritis or rheumatoid arthritis lasting 2 weeks or more. Outcomes were discontinuations (all cause, lack of efficacy, adverse event, gastrointestinal adverse event), endoscopically detected ulcers, gastrointestinal or cardio-renal events, and major changes in haematological parameters. The main comparisons were celecoxib (all doses) versus placebo, paracetamol (acetaminophen) 4,000 mg daily, rofecoxib 25 mg daily, or nonsteroidal anti-inflammatory drugs (NSAIDs) (naproxen, diclofenac, ibuprofen, and loxoprofen). For NSAIDs, celecoxib was compared both at all doses and at licensed doses (200 to 400 mg daily). Thirty-one trials included 39,605 randomised patients. Most patients had osteoarthritis and were women of average age 60 years or above. Most trials lasted 12 weeks or more. Doses of celecoxib were 50 to 800 mg/day. Compared with placebo, celecoxib had fewer discontinuations for any cause or for lack of efficacy, fewer serious adverse events, and less nausea. It had more patients with dyspepsia, diarrhoea, oedema, more adverse events that were gastrointestinal or treatment related, and more patients experiencing an adverse event. There were no differences for hypertension, gastrointestinal tolerability, or discontinuations for adverse events. Compared with paracetamol, celecoxib had fewer discontinuations for any cause, for lack of efficacy, or diarrhoea, but no other differences. Compared with rofecoxib, celecoxib had fewer patients with abdominal pain and oedema, but no other differences. Compared with NSAIDs, celecoxib had fewer symptomatic ulcers and bleeds, endoscopically detected ulcers, and discontinuations for adverse events or gastrointestinal adverse events. Fewer patients had any, or a gastrointestinal, or a treatment-related adverse event, or vomiting, abdominal pain, dyspepsia, or reduced haemoglobin or haematocrit. Discontinuations for lack of efficacy were higher. No differences were found for all-cause discontinuations, serious adverse events, hypertension, diarrhoea, nausea, oedema, myocardial infarction, cardiac failure, or raised creatinine. Company clinical trial reports present much more information than published papers. Adverse event information is clearly presented in company clinical trial reports, which are an ideal source of information for systematic review and meta-analysis.

Multinucleated epithelial giant cells (MEG) simulating viral cytopathic effect and/or dysplasia have been reported in the esophagus in association with inflammation, but the occurrence of similar cells in the colon has not been documented. Twenty-three colon specimens (22 biopsies and 1 partial colectomy) featuring MEG from 21 patients were evaluated for a variety of histologic features and correlated with clinical, endoscopic, and follow-up data. Patients included 9 males and 12 females (mean age, 64.9 years; range, 45-86 years). Eleven cases were obtained from 10 asymptomatic patients undergoing surveillance biopsies. Presenting symptoms in the remaining patients were dyspepsia, anemia, abdominal pain, and hematochezia. Over half (13 of 23) of the specimens were from descending and rectosigmoid colon, and almost all were visualized as polyps on endoscopy. Microscopically, all but 1 of the cases featured multiple MEG (range, 6 to >50 cells per biopsy) in the base and mid crypt zones of inflamed polyps with serrated architecture. Immunohistochemical stains for CMV, HSV, adenovirus, EBV, and polyoma virus were negative and no viral particles were identified on ultrastructural examination. Nuclear staining for hMLH1 and hMSH2, markers of microsatellite instability, was similar in distribution to adjacent serrated crypts, but reduced staining intensity was noted in occasional multinucleated cells. Expression of Ki-67 and cleaved caspase 3 was consistent with a quiescent or low proliferative state. Clinical follow-up was available for 9 patients (mean duration, 22.7 months). One patient died of heart failure; all others were well at last follow-up. Bizarre MEG may occasionally be seen within the crypts of inflamed polyps with serrated architecture, raising concern for dysplasia or viral infection. Immunohistochemical and ultrastructural studies fail to establish a viral etiology, and follow-up does not indicate clinically aggressive disease. These changes appear to represent a nonspecific, possibly degenerative response to inflammation and injury, and should be distinguished from dysplasia.
