Enteral nutrition (EN) has several advantages over parenteral nutrition (PN) for postoperative/posttrauma patients. Modern technologies for tube-feeding have made early EN possible. Jejunal tube-feeding has advantages over gastric tube-feeding: faster metabolic recovery, less
vomiting
, and less risk of
regurgitation
and aspiration. Immediate or early EN stimulates the splanchnic and hepatic circulations, improves mucosal blood flow, prevents intramucosal acidosis and permeability disturbances, and eliminates the need for stress ulcer prophylaxis. Saliva containing important antimicrobial substances and gastric acidity are important in sepsis prevention. Chewing, saliva, and gastric acidity support gastric nitric oxide (NO) release, important for mucosal blood flow, gastrointestinal (GI) motility, mucus formation, and bacteriostasis. An oral supply of NO-donating substances and chewing of nitrate-rich food, such as lettuce or spinach, can be useful. Oral and mucosa-protective lipids are recommended. H2 blockers and saliva-inhibiting drugs are avoided. Immediate EN should be given, starting with 25 ml/hr and increasing to 100 ml/hr over 24 to 48 hours. For the immunocompromised patient special attention should be given to the purity of water. Bottled water can contain bacteria such as Pseudomonas. Food antioxidants such as glutathione, vitamin E, and beta-carotenes are important. Ingredients for the colonic mucosa are important. Approximately 10% of caloric need is satisfied by so-called colonic food (prebiotics), fermented at the level of the colonic mucosa to produce colonic mucosa nutrients and to prevent gut origin sepsis. More than 10 g of fiber per day is recommended. The fermenting flora (probiotic flora) is deranged owing to disease or antibiotic treatment, and resupply of flora is important. A new concept of ecoimmune nutrition is presented for enteral supply of mucosa-reconditioning ingredients: new surfactants, pseudomucus, fiber, amino acids such as arginine, and mucosa-adhering Lactobacillus plantarum 299.

Fainting syncopal events are caused by a transient functional neuronal paralysis. Reflex syncope happens for brainstem involving mediated by peripherical afferents. Sometimes gastroesophageal reflux (GER) has been implicated in the development of obstructive apnea. Gastroesophageal reflux, despite the absence of a clinical history of
vomiting
and
regurgitation
, is observed in a significant proportion of infants presenting with ALTE (Apparent Life Threatening Event): an episode characterized by some combination of apnea, color change, marked change in muscle tone, choking or gagging. Though a cause-and-effect relationship between GER and the development of ALTE remains to be established a possible direct relationship between oesophageal acidification and the onset of alterations in cardiopulmonary function and impairment of consciousness can be hypothesized. We refer the case of two female infants that developed recurrent ALTE(s) characterized by paleness, change in muscle tone and loss of consciousness. The infants resulted affected respectively by a mild and severe gastroesophageal reflux (score: 40, > 50); in one case an episode of GER was recorded by the intraoesophageal pH-monitoring during a syncopal episode. The treatment with antiacid drugs was effectual and the infants did not present ALTE(s). The cases presented are in favour of a routine search of gastroesophageal reflux in infants presenting with one or recurrent ALTE(s). The identification of these infants will permitt to develop a correct strategy of treatment.

Twenty-six children (mean age: 16.3 months) with
vomiting
and/or respiratory symptoms and 28 children (mean age 10.5 months) with
vomiting
and/or
regurgitation
underwent dual-site 24-hour oesophageal pH recording. Thirty-nine children had gastro-oesophageal reflux and in all of them, irrespective of respiratory symptoms, distal oesophageal acid exposure was significantly (p < 0.01) longer than proximal exposure. Furthermore, data from the proximal pH electrode were not significantly different between children with and without respiratory symptoms for any of the variables studied. In conclusion, no single features of reflux pattern, as determined by 24-hours pH-metry, account for respiratory symptoms in children with documented gastro-oesophageal reflux.

Helicobacter pylori-like organisms (Hp) and polymorphonuclear leucocytes (PMNs) in 2614 gastroduodenal biopsies from 602 patients with dyspepsia, in Al Ain, United Arab Emirates, between October 1990 and October 1992, were histologically graded to determine the prevalence of Hp gastritis and their utilization in the evaluation of treatment efficacy in these patients. Symptoms of functional dyspepsia included, in order of frequency, abdominal pain or discomfort, flatulence, burning sensation,
regurgitation
, fullness, nausea,
vomiting
, bloating and belching. The biopsies were paraffin embedded, sectioned and stained with hematoxylin and eosin (H and E) to grade the inflammation. In addition to H and E, several special stains including modified Giemsa (MG), Wharthin-Starry silver and cold Ziehl-Neelsen stains were utilized to clearly identify Hp organisms. Giemsa method was found to be superior to other special stains in visualizing the Hp organisms in paraffin sections, and was utilized in every case. Two immunohistochemical markers for B cells (CD20) and T cells (CD45RO) were utilized for labeling lymphocytes infiltrating the lamina propria of the gastroduodenal biopsies in formalin-fixed paraffin-embedded sections. H and E and MG stained sections were utilized to count PMNs and Hp, and were graded 0, 1, 2, and 3, corresponding to none, mild, moderate, and severe grades of the Sydney system for classification of gastritis, respectively. Of the total initial 2318 endoscopic biopsies, 98.8% of the patients had suitable biopsies for histologic evaluation. Unsuitable biopsies were recovered from patients with gastric carcinoma. Inflammation was seen in 98.5% of 595 patients with suitable biopsies. In 74.5% of these patients the inflammation was active; 37.5, 32.5 and 4.5% had mild, moderate and severe active inflammation, respectively. In the remaining 24% of the 595 patients, the gastritis was chronic without activity or atrophic changes. As many as 73.6% of the patients with suitable biopsies were Hp positive; 39.8, 29.1 and 4.7% had grades 1, 2 and 3 Hp, respectively. Intestinal metaplasia was found in 28.9% of the 602 patients, and was seen more often in Hp positive than Hp negative patients (34.5 vs 14%, P < 0.005, for d.f. = 1; chi 2 = 10.35). Of the Hp positive patients, 172 and 46 patients attended the first and second follow-up endoscopy visits, respectively. The triple treatment was composed of one dose of tinidazole (2gm), doxycycline, 200 mg initial dose and 100 mg daily for two weeks, and bismuth subcitrate (Gist-Brocades nv, Delft, The Netherlands), 2 tablets twice daily for 4 weeks. After triple drug treatment, eradication of Hp was accomplished, histologically, in 38.4 and 45.7% of the patients on first and second follow-up visits, respectively. Thus, the Sydney system-based grading scale provides an objective histological evaluation of Hp gastritis for accurate prevalence studies, and may prove to be of value in estimating treatment efficacy.

Abnormalities in gastrointestinal motility have been reported in a substantial proportion of patients with functional dyspepsia, supporting the use of prokinetic drugs for treatment of dyspeptic symptoms. To evaluate efficacy and safety of levosulpiride in short-term treatment, 1298 patients were enrolled in a double-blind multicentric study carried out in 45 Italian Gastroenterology Departments. Patients were randomly assigned to either levosulpiride (25 mg tid), domperidone (10 mg tid), metoclopramide (10 mg tid) or placebo (1 tablet tid) for 4 weeks. Patients were selected on the basis of: a) occurrence in the last 4 weeks of at least 5/10 selected symptoms (anorexia, nausea,
vomiting
, upper abdominal pain, postprandial bloating, abdominal fullness, early satiety, belching, heartburn,
regurgitation
), severity of which should reach/exceed a total score of 8, as assessed by a specific scale ranging from 0 (absent) to 3 (severe); b) normal results of routine biochemical, ultrasound and endoscopic examinations. In addition, each patient subjectively evaluated efficacy of treatment by a visual analogue scale. Significant improvement was recorded for all symptoms at days 10 and 28 in all groups (p < 0.001), but levosulpiride was significantly (p < 0.01) superior to domperidone, metoclopramide and placebo both in the overall clinical improvement scale as well as in a subgroup of symptoms (postprandial bloating, epigastric pain, heartburn). Active treatments and placebo were comparable as far as concerns occurrence of side-effects (12-20%) including galactorrhoea, breast tenderness and menstrual changes.

Cisapride is a substituted benzamide with gastrointestinal prokinetic effects presumed to be due to the enhancement of the physiological release of acetylcholine at the myenteric plexus. In a multicentre study, 189 patients with nonulcer dyspepsia (NUD) received single-blind placebo treatment for two weeks. A total of 123 patients with no or minimal response to placebo and epigastric pain of at least moderate severity and frequency were randomly assigned to one of the three parallel double-blind treatments for six weeks: cisapride 10 mg tid, cisapride 20 mg tid or placebo. The severity and frequency of individual symptoms (epigastric pain, heartburn, nausea,
vomiting
anorexia, postprandial discomfort,
regurgitation
, lower abdominal pain, bloating and constipation) were assessed on a four- and five-point categorical scale, respectively, by the investigator at three on treatment visits and by patients in a daily diary. Analysis of investigator and patient assessments for differences in symptom severity x frequency composite scores among the three treatment groups showed no statistically significant differences for individual symptoms or symptom clusters. As assessed by the investigator, and compared with baseline, cisapride 20 mg tid significantly (P < 0.05) improved epigastric pain, bloating and early satiety as well as improved the total symptom cluster. Investigator evaluation of the five most severe and frequent symptoms for each patient showed statistically significant improvement in each treatment group. For patient diary assessments, statistically significant within-treatment improvement of the total symptom cluster, the five most severe symptoms cluster, bloating and early satiety was observed for both cisapride 20 mg and placebo, whereas epigastric pain significantly (P < 0.05) improved in all three treatment groups. Investigator evaluation of global response (good+excellent) rate at the end of the six week treatment period was 38% for cisapride 20 mg, 47% for cisapride 10 mg and 33% for placebo. No statistically significant difference in this parameter among treatments was noted. Cisapride was well tolerated at both doses with a side effect profile comparable with that of placebo. It is concluded that in this double-blind multicentre study with a single-blind two-week placebo run in phase, cisapride 10 mg tid and 20 mg tid were not effective compared with placebo in improving symptoms in NUD patients. This study re-emphasizes the good prognosis of patients with NUD, with 14% of patients improving in the two-week placebo run-in phase and a further 33% improving in the next six weeks while on placebo. Within-treatment analysis of investigator assessments showed improvement for cisapride 20 mg tid suggesting a trend of efficacy at this dose.

We investigated symptoms suggestive of swallowing problems in patients with primary biliary cirrhosis, some of whom displayed features of sicca complex. A prospective study of 95 consecutive patients with primary biliary cirrhosis was conducted at a single teaching hospital using a questionnaire administered over the telephone. Some symptoms of sicca complex (dry mouth and/or dry eyes) were found in 65 patients (68.4%). Subjective xerostomia alone was present in 45 patients (47.4%). The questionnaire revealed an increase in incidence of dysphagia in xerostomia subjects, affecting 21 of 45 patients, compared with 6 of 50 non-xerostomia patients. Multivariate logistic regression analysis showed that confounding factors such as age, obesity, cigarette smoking, and medications associated with a dry mouth could not explain these findings. Twenty-eight patients complained of hoarseness, 23 of coughing, and 14 of wheezing, all of which were significantly more frequent than in the 50 patients without xerostomia. Heartburn affected 17 xerostomia patients and 15 non-xerostomia patients, indicating no difference in frequency between these two groups, even after age, obesity, cigarette smoking, and medications associated with heartburn were considered in the multivariate analysis. Acid
regurgitation
, nausea, and
vomiting
were also similar in frequency between patients with and without xerostomia. Swallowing problems, manifested primarily as dysphagia, are common in primary biliary cirrhosis patients who have subjective xerostomia.

Gastro-oesophageal reflux in children is different in several aspects from in adults. Pathophysiologically, 50% of reflux episodes are due to increased abdominal pressure which overcomes the lower oesophageal sphincter pressure. This pathophysiological abnormality disappears in children at the age of 1.5-2 years. Treatment is therefore different and aimed at thickening the gastric contents to inhibit reflux (Nutrition, Gaviscon, Algicon). The child is placed in the anti-Trendelburg position when asleep. No further investigation or intensification of treatment is necessary in young children under the age of 2 years unless complications are present. With complicated gastro-oesophageal reflux, treatment in children is comparable to that in adults; the effects of H2 antagonists and proton-pump inhibitors are identical. Long-term complications of gastro-oesophageal reflux are rare. In the near sudden death syndrome or acute life-threatening events in infants due to total sphincter relaxation aspiration is possible and should be prevented. Optimal treatment and monitoring are mandatory. In mentally handicapped children rumination is more prominent than gastro-oesophageal reflux. It is difficult to distinguish between
vomiting
,
regurgitation
and rumination. Treatment of oesophagitis might improve quality of life. When clear eosinophilic oesophagitis is observed food allergy should be considered and appropriately treated.

Rumination is a syndrome characterized by repetitive
regurgitation
of small amounts of food from the stomach. The food is then partially or completely rechewed, reswallowed, or expelled. This syndrome is relatively common in infants and mentally challenged persons, but it also occurs in adults with normal intelligence. The rumination syndrome is an underappreciated condition in adults who frequently receive a misdiagnosis of
vomiting
due to gastroparesis or gastroesophageal reflux. Difficulties in establishing the correct diagnosis may be caused by a lack of awareness of the condition among physicians. This syndrome must be considered in the differential diagnosis of a patient with
regurgitation
,
vomiting
(especially postprandial), and weight loss. Reassurance, explanations, and behavioral therapy are currently the mainstays of treatment in adults with normal intelligence who have the rumination syndrome. Appropriately controlled trials are needed to establish the best therapy.

Hypertrophic pyloric stenosis (HPS) is very rare during the newborn period. Here we present a fullterm male neonate with abundant hematemesis 12 hours after birth which interrupted oral feeding. Bleeding subsided within three days after conservative measures, and oral feeding was restarted but not tolerated. The
vomiting
was effortless and nonbilious. An upper gastrointestinal series revealed gastric dilatation and partial obstruction of the gastric outlet. HPS was found by laparotomy on the fourth day and Fredet-Ramstedt pyloromyotomy relieved the gastric emptying. This is one of the few cases of HPS present at birth, which was diagnosed and surgically treated early, and we suggest a congenital etiology in previously reported cases of HPS. Hypertrophic pyloric stenosis (HPS) is a common cause of pediatric surgery. Usually young infants are involved; HPS is extremely rare in neonates and infants older than 6 months.
Vomiting
typically begins between the 3rd and 6th week of life, although some infants may have mild symptoms like
regurgitation
from birth.
