A total of 502 children up to the age of 14 years were treated for iron deficiency or overt anemia. ITF 282 was prescribed to 256 children, and a commercially available ferrous polystyrene sulphonate preparation to 246, in a randomized double-blind, double-dummy, ten-center trial. One oral vial of ITF 282 (60 mg iron) was administered once a day to children weighing up to 40 kg; and twice a day to children with body weight equal or superior to 40 kg. In the reference group, oral vials of polystyrene sulphonate (52.5 mg iron) were administered once a day to children weighing up to 40 kg, and twice a day to children weighing 40 kg or more. Treatments lasted 60 days. The treatments' efficacy and tolerability were evaluated taking into consideration: special hematology, symptomatology, safety hematology and hematochemistry, urinalysis. At the end of treatment, the trend was detected to the normalization of the main hematologic parameters in both groups (hemoglobin, hematocrit, ferritin, blood iron, transferrin saturation, MCHC). Although in the first month the reference treatment appears to provide somewhat faster results, significantly greater values of blood iron are observed at the end of the observation in the ITF 282 group, indicating a more progressive and steady therapeutic effect. The overall clinical rating was, although not significant, in favor of ITF 282, with a failure rate of 18.0 vs 24.0%. The general tolerance, although favorable with both treatments, was significantly more favorable with ITF 282. With this medication, 13 patients complained of 13 events (1 heartburn, 6 constipation, 6 abdominal pain) vs 48 events reported by 43 patients with the reference medication (1 heartburn, 2 epigastric pain, 14 constipation, 14 abdominal pain, 3 skin rash, 14 vomiting). These observations confirm that, although the most modern preparations of ferrous ions exhibit a relatively low frequency of adverse events of limited clinical concern, it is nevertheless possible to decrease (with the use of more "physiologic" preparations in which the iron is reversibly bound to a protein carrier) the prevalence and, tendentially, duration and intensity of such events without prejudice for the clinical efficacy. Therefore, the good clinical tolerability of ITF 282 effectively removed one of the main obstacles to the correct compliance with iron treatments (necessarily to be taken long-term), as reduced the risks of undesired events in a particularly susceptible population subgroup, such as children.

From 1985 to 1993, 49 patients (35 women and 14 men) with diaphragmatic hernia and associated anemia underwent surgical repair. The median age was 64.5 years (range 24 to 84 years). Hematologic and gastroenterologic evaluations revealed no other potential cause of bleeding. Each patient had a diaphragmatic hernia. The median time between the diagnosis of anemia and surgical repair was 36 months (range 1 to 334 months). Forty-five patients (91.8%) had received replacement therapy, including iron for 43 and blood transfusions for 32 (median 6 units; range 2 to 70 units). Forty-six patients (93.9%) had symptoms: heartburn in 28, early satiety with bloating in 19, regurgitation in 11, dysphagia in 7, and aspiration in 4. Preoperative upper gastrointestinal endoscopic evaluation demonstrated gastric erosions at the level of the hiatus in 22 patients (44.9%), esophagitis in 7, stenosis in 1, and Barrett's disease in 1. An uncut Collis-Nissen fundoplication was performed in 44 patients, Belsey fundoplication in 2, a cut Collis-Nissen fundoplication, Nissen fundoplication, and Hill repair in 1 each. There was one operative death (2% mortality). Complications occurred in 18 patients (36.7%). Follow-up was complete and ranged from 4 to 103 months (median 63 months). Forty-five patients (91.8%) had resolution of their anemia. Functional results were excellent in 40 patients (81.6%), good in 2 (4.1%), fair in 4 (8.2%), and poor in 3 (6.1%). In most patients with diaphragmatic hernia and associated anemia refractory to medical treatment, surgical repair can result in successful resolution of the anemia.

Twenty-seven patients underwent consecutive elective laparoscopic repair of paraesophageal hiatal hernia between October 1992 and June 1997. There were 24 females and 3 males. The average age was 68 years (range, 46-86) and average weight was 173 pounds (range, 122-243 lb.). Presenting symptoms were: postprandial epigastric pain or pressure in 19 patients, postprandial dyspnea in 7 patients, anemia in 5 patients, postprandial vomiting of food in 5 patients, and 1 patient had postprandial palpitation. Heartburn was present in 9 patients. Five patients had a history of symptoms of intermittent volvulus. History of hiatal hernia was present in 19 patients ranging from 6 months to 38 years in duration. The operative procedure included a laparoscopic reduction of the herniated stomach, excision of the hernia sac, and closure of the diaphragmatic defect with placement of mesh graft. Anterior gastropexy was performed on all patients except two who had a Nissen fundoplication due to severe reflux symptoms. Seven patients had laparoscopic cholecystectomy at the same time and one patient had an excision of a small benign gastric leiomyoma of the fundus. The average operative time was 2:54 hours (range, 1:35-4:05 hrs.). The average hospital stay was 3.8 days (range, 2-8 days). One patient had a postoperative stroke and recovered quickly. Follow-up of 1 to 56 months showed no recurrence of the hernia. Two patients complained of some epigastric pain and six patients had occasional mild reflux that was easily controlled medically. Laparoscopic repair of paraesophageal hernia is a safe procedure with a short hospital stay and recovery time. Using mesh graft decreases the risk of developing an iatrogenic parahiatal hernia. The addition of Nissen fundoplication is not necessary unless the patient has objective findings of reflux.

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.

Gastroesophageal reflux is a very common disorder. Typical symptoms are heartburn, regurgitation and chest pain. Recently, it has been demonstrated that gastroesophageal reflux may generate or worse extraesophageal symptoms such as asthma, chronic bronchitis, posterior laryngitis, and chronic cough. The diagnosis of gastroesophageal reflux is suggested by typical symptoms which improve under a therapy with proton pump inhibitors. pH-monitoring over 24 hours is able to establish directly the diagnosis by measuring acid reflux into the esophagus. Manometry detects the two most common causes of gastroesophageal reflux: insufficiency of the lower esophageal sphincter or esophageal motility abnormalities. Gastroesophageal reflux can lead to reflux esophagitis, which is diagnosed endoscopically. An endoscopy should routinely be performed in case of dysphagia, anemia, or loss of weight. A long-term sequela of gastroesophageal reflux is the development of Barrett's-esophagus, a condition which has to be verified by endoscopy and biopsy. This premalignant lesion is defined by a metaplastic change from the normal squamous mucosa to a specialized intestinal epithelium characterized by goblet cells. Because dysplasia in these metaplastic areas can lead to esophageal adenocarcinoma, regular endoscopic surveillance with biopsies is recommended. Gastroesophageal reflux can significantly impair the quality of life and can cause complications that include the neoplastic progression from Barrett's esophagus to carcinoma. Therefore, appropriate diagnostic procedures and adequate therapy are required. This article summarizes the diagnostic approach to patients with gastroesophageal reflux, reflux esophagitis and Barrett's-esophagus. The impact of endoscopy, pH-monitoring, esophageal manometry, radiology and scintigraphy are reviewed.

This review describes the current state of knowledge on the hazards of exercise and the potential benefits of physical activity on the gastrointestinal tract. In particular, acute strenuous exercise may provoke gastrointestinal symptoms such as heartburn or diarrhoea. A substantial part (20-50%) of endurance athletes are hampered by these symptoms which may deter them from participation in training and competitive events. Nevertheless, these acute symptoms are transient and do not hamper the athlete's health in the long term. The only exception is repeated gastrointestinal bleeding during training and competition, which in the long term may occasionally lead to iron deficiency and anaemia. In contrast, repetitive exercise periods at a relatively low intensity may have protective effects on the gastrointestinal tract. There is strong evidence that physical activity reduces the risk of colon cancer by up to 50%. Less convincing evidence exists for cholelithiasis and constipation. Physical activity may reduce the risk of diverticulosis, gastrointestinal haemorrhage, and inflammatory bowel disease although this cannot be substantiated firmly. Up to now, underlying mechanisms are poorly understood although decreased gastrointestinal blood flow, neuro-immuno-endocrine alterations, increased gastrointestinal motility, and mechanical bouncing during exercise are postulated. Future research on exercise associated digestive processes should give more insight into the relationship between physical activity and the function of the gastrointestinal tract.

Usual gastroesophageal reflux (GER) presentations are heartburn and acid regurgitation. The prevalence in occidental population ranges from 5 to 45% according to symptoms frequency. Oesophagitis is observed in 30 to 50% of examined patients and only erosive and ulcerative lesions must be considered. Distinction is made between non-severe oesophagitis (isolated loss of substance), severe oesophagitis (circonferential loss of substance) and complicated oesophagitis (stenosis, ulcerations, brachyoesophagus). 24-hour pH-monitoring analyses reflux duration and relations between symptoms and reflux specially in unusual extraoesophageal presentations. Symptoms and quality of life are the main criteria for staging. In few patients, oesophagitis is severe. Complications (stenosis, ulcerations, bleeding, endobrachyoesophagus) are observed in 10 to 15% of cases. Endobrachyoesophagus with intestinal metaplasia is a risk for neoplasia. The consensus conference proposes this initial therapeutic strategy. In cases of time-spaced symptoms: antiacids, alginic acid or low doses of anti-H2 with life style changes. In cases of typical frequent symptoms, in patients younger than 50 years: 4-weeks treatment with half dosed proton pump inhibitors (PPI) or standard doses of anti-H2 or prokinetics. Nowadays, the majority of the experts propose empiric full-dose treatment. This attitude is more logical as total symptoms suppression with full dose PPI brings positive clues for exact GOR diagnostic without endoscopy. In patients older than 50 years or with alarming symptoms (weight loss, dysplagia, bleeding, anemia): endoscopy must be performed. Patients with non severe oesophagitis: PPI without checking endoscopy. In patients with severe or complicated oesophagitis: 8-weeks treatment following by endoscopy; in non relieved patients: doses are increased. In cases of extraoesophageal presentations: standard PPI treatment during 4 to 8 weeks if GER is well established. In long term strategy, if recidives are rare: intermittent treatment. In early and frequent recidives: long term adapted PPI or surgery. Stenosis are treated by PPI, pneumatic dilatation or surgery if unsuccessful. Brachyoesophagus must be checked by endoscopy every 2 years (malignancy risk).

Dyspepsia is defined as chronic or recurrent pain or discomfort centred in the upper abdomen. Early satiety, nausea, vomiting, or bloating are often also present. Dyspepsia should be differentiated from gastro-oesophageal reflux disease, whose predominant symptoms are heartburn and acid regurgitation. Prevalence rates vary between 25% and 40%, and dyspepsia is the main reason for consulting GPs: 3-5% of all visits. Older patients and patients presenting with alarm symptoms (weight loss, anaemia, jaundice, dysphagia, bleeding) should undergo endoscopy, but apart from this no other management strategy has been agreed upon. Management strategies based on non-invasive H. pylori testing will probably prove cost-effective and safe. However, the results of clinical trials are awaited before guidelines can be offered. The symptomatic effects of treating patients with functional dyspepsia with either acid inhibitors, prokinetics, or H. pylori eradication therapy are difficult to predict and are usually quite modest.

The effects of the prostaglandin I2 derivative beraprost sodium (Dorner) on ankle pressure index (AP; ankle joint-to-upper extremity systolic pressure ratio), subjective symptoms, and intermittent claudication were investigated in diabetic patients with arteriosclerosis obliterans (ASO). Forty patients (25 men and 15 women), mean age 63.9 years, were enrolled in this study. ASO was grade I in 30 patients, grade II in seven, grade III in one, and grade IV in two according to the Fontaine classification. They were administered six tablets (20 microg/tablet) of beraprost sodium daily for 6 months. At 3 and 6 months, API had significantly increased and symptoms such as coldness, numbness, and lack of feeling in the lower extremities were significantly improved. Ten evaluable patients increased ambulatory distance by approximately threefold, suggesting an improvement in intermittent claudication. Adverse reactions were experienced by five (12.5%) of the 40 patients (one case each of headache, dull headache, pain in the posterior region of the neck, heartburn, stomach discomfort, and anemia), but all were mild and resolved without treatment. Beraprost sodium was shown to improve API and symptoms in the lower extremities in diabetic patients with ASO, suggesting that it is useful in treating peripheral circulatory disorders in such patients.

Although gastroesophageal reflux disease (GERD) is frequently referred to as a continuous spectrum, it is more useful to consider GERD as 2 discrete entities with several subsets that differ in pathophysiology, clinical presentation, natural history, and therapy. One entity is classic severe acid reflux with erosive esophagitis and its complications. Barrett's esophagus is an important subset of this group, with markedly increased acid exposure and an increased risk of adenocarcinoma. The second entity is nonerosive reflux disease (NERD) with minimal or no esophagitis. Patients with NERD do not develop local mucosa complications, like stricture or Barrett's esophagus, but their symptom severity can equal that of erosive esophagitis. Acid is involved in the symptoms of many but not all NERD patients. This acid dependence is evident either as an increase in esophageal acid reflux or a hypersensitivity to acid, and both generally respond well to proton pump inhibitor (PPI) therapy. NERD patients who are not acid-dependent have what is called functional heartburn; GERD-like symptoms are present, but there is no obvious involvement of refluxed acid. An important subset of GERD is refractory GERD, which consists of patients who fail aggressive PPI therapy. Parallel findings with other refractory syndromes can be anticipated; however, there are indications that psychosocial factors play a major role in refractory GERD, and these patients may benefit more from an integrated biopsychosocial approach. Diagnosis of GERD is usually made on clinical grounds, often supplemented by a therapeutic trial with antisecretory agents. Endoscopy is reserved for patients with alarm symptoms, such as dysphagia, anemia, or weight loss, or to detect Barrett's esophagus. Endoscopy is not useful to exclude the diagnosis of GERD because it will be negative in 70% of cases in primary care. Ambulatory 24-hour esophageal pH monitoring is necessary only when the diagnosis is in doubt, the patient fails medical management, or surgery is contemplated.
