Eosinophilic enteritis is a rare condition of unknown aetiology, although it is generally believed to be due to intestinal allergy. It may mimic
peptic ulcer
, subacute (or chronic) intestinal obstruction, gastroenteritis, irritable bowel syndrome, and inflammatory bowel disease. The diagnosis is often difficult to make and most cases are only diagnosed after laparotomy/ laparoscopy and biopsy. It can be successfully treated with corticosteroids. We report a case of Eosinophilic enteritis in a 27 year old woman the symptoms of which appeared within six weeks of childbirth. With repeated episodes of abdominal pain,
vomiting
, occasional loose stools with weight loss, she was investigated and treated for many weeks in three hospitals without success. All investigations were inconclusive. Finally laparotomy revealed inflamed segments of small bowel, a biopsy of which showed Eosinophilic enteritis. The patient was subsequently treated successfully with Prednisolone.

Diabetic gastroparesis is a common and debilitating condition affecting millions of patients with diabetes mellitus worldwide. Although gastroparesis in diabetes has been known clinically for more than 50 years, treatment options remain very limited. Until recently, the scientific literature has offered few clues regarding the precise aetiology of gastric dysfunction in diabetes.Up to 50% of patients with diabetes may experience postprandial abdominal pain, nausea,
vomiting
and bloating secondary to gastric dysfunction. There is no clear association between length of disease and the onset of delayed gastric emptying. Gastroparesis affects both type 1 (insulin dependent) and type 2 (non- insulin dependent) forms of diabetes. Diagnosis requires identifying the proper symptom complex, while excluding other entities (
peptic ulcer disease
, rheumatological diseases, medication effects). The diagnosis of gastroparesis may be confirmed by demonstrating gastric emptying delay during a 4-hour scintigraphic study. Treatment options are limited and rely on dietary modifications, judicious use of available pharmacological agents, and occasionally surgical or endoscopic placement of gastrostomies or jejunostomies. Gastric pacing offers promise for patients with medically refractory gastroparesis but awaits further investigation. Current pharmacological agents for treating gastroparesis include metoclopramide, erythromycin, cisapride (only available via a company-sponsored programme) and domperidone (not US FDA approved). All of these drugs act as promotility agents that increase the number or the intensity of gastric contractions. These medications are not uniformly effective and all have adverse effects that limit their use. Cisapride has been removed from the open market as a result of over 200 reported cases of cardiac toxicity attributed to its use. Unfortunately, there is a paucity of clinical studies that clearly define the efficacy of these agents in diabetic gastroparesis and there are no studies that compare these drugs to each other. The molecular pathophysiology of diabetic gastroparesis is unknown, limiting the development of rational therapies. New studies, primarily in animals, point to a defect in the enteric nervous system as a major molecular cause of abnormal gastric motility in diabetes. This defect is characterised by a loss of nitric oxide signals from nerves to muscles in the gut resulting in delayed gastric emptying. Novel therapies designed to augment nitric oxide signalling are being studied.

OBJECTIVE: To present a current review about pathogenesis, pathophysiology, diagnosis, and treatment of
peptic ulcer disease
in children, based on the reviewed publications and the author personal experience. METHODS: We revised the most relevant articles about
peptic ulcer
in children, published from the last 20 years. RESULTS: The gastroduodenal
peptic ulcer
is very common in adults, mostly in the developing countries. Although it is less frequent in children, the optical fibroendoscopy has improved the number of diagnosed cases. The
peptic ulcer
is classified as its etiology in primary and secondary. The secondary
peptic ulcer
is related to a subjacent disease or use of drugs, while the primary ulcer happens in the absence of underlying systemic diseases The primary duodenal ulcer is the most common presentation, and there are strong evidences of the H. pylori association in the etiology. Clinical presentation changes with age and ulcer type. Secondary ulcers are mostly acute and sometimes dramatic, while the primary ones have a chronic evolution mostly similar to patients with functional recurrent abdominal pain, but the presence of epigastric pain, feeding-related pain,
vomiting
, bleeding, familiar history for
peptic ulcer
, nocturnal pain, and male gender are strongly related to
peptic ulcer
. The acid antisecretory agents have great efficacy on relieving symptoms and solving ulcerate lesion, although the H. pylori eradication itself prevents primary duodenal ulcer recurrence. CONCLUSIONS: The primary
peptic ulcer
involve many factors in Its etiopathogenesis, being H. pylori the most important of them Although there isn t yet a ideal therapeutic course. The antibiotics play an important role in
peptic ulcer
and the H. pylori research must be done for na accurate diagnosis and treatment.

Surgical emergencies can be missed easily in children, who are not always able to volunteer relevant information. Awareness of the entities discussed in this review might help the EP uncover subtle clues to early diagnoses that might not be initially apparent. Ill-appearing children who have abdominal pain and
vomiting
should be considered to have ischemic or necrotic bowel until proven otherwise. Possible diagnoses include volvulus, intussusception, and necrotizing enterocolitis. Bilious vomiting, especially in a young infant, should be considered to be an indication of a high bowel obstruction such as midgut volvulus, which warrants immediate surgical consultation. Significant rectal bleeding with abdominal pain can result from intussusception, volvulus, or an inflamed Meckel's diverticulum. Rectal bleeding with unstable vital signs can result from an upper GI bleed (eg,
peptic ulcer disease
). Painless rectal bleeding can result from a Meckel's diverticulum, polyps, arteriovenous malformation, or a tumor. Examination of the genitalia is imperative, especially in boys, to exclude the possibility of an incarcerated hernia or testicular torsion.

Due to its prevalence, impact on quality-of-life and the associated significant health resource utilization, dyspepsia is a major healthcare concern. The available management strategies for uninvestigated dyspepsia include prompt endoscopy, the 'test-and-treat' strategy for Helicobacter pylori, and empiric antisecretory therapy. There is consensus that endoscopy should be reserved for patients with alarm features (e.g. symptom onset after 45 years of age, recurrent
vomiting
, weight loss, dysphagia, evidence of bleeding, anaemia), H. pylori-positive individuals who fail test-and-treat, and those with an inadequate response to empiric antisecretory therapy. Factors influencing the decision between test-and-treat and empiric antisecretory therapy in uninvestigated dyspepsia include the local prevalence of H. pylori and
peptic ulcer disease
and the proportion of ulcers attributable to H. pylori. For uninvestigated dyspepsia in patients without alarm features, test-and-treat is the preferred initial management method in Europe based on the relatively high prevalence of H. pylori/
peptic ulcer disease
whereas empiric antisecretory therapy is preferred in many parts of the United States, where the prevalence of H. pylori/
peptic ulcer disease
is relatively low. In patients with non-ulcer dyspepsia, H. pylori eradication and empiric antisecretory therapy result in comparable and small, but statistically significant, improvements in dyspepsia. Empiric antisecretory therapy is the preferred initial method of managing non-ulcer dyspepsia in Europe and the US. The test-and-treat approach would receive increased enthusiasm if H. pylori cure is shown to prevent development of gastric cancer in non-ulcer dyspepsia patients in a large Western trial.

A 16-year-old boy was admitted with an 8-year history of abdominal pain,
vomiting
, and growth retardation. There was no history of
peptic ulcer
or caustic ingestion. He was severely cachexic, and barium meal showed a dilated stomach with delayed gastric emptying time and no contrast in the duodenum afterward. Exploratory laparotomy demonstrated a grossly dilated stomach with a smooth wall and a stenotic ring at the pylorus but without any muscular hypertrophy. There was no extrinsic compression of the pylorus or any scarring near it. Heineke-Mikulicz' pyloroplasty was performed. Histopathological examination of the pylorus showed normal cellular pattern without any neoplastic or inflammatory cells. The patient improved postoperatively and gained 8 kg in the first month following the operation.

The authors present the case of a male patient, aged 56, operated (partial gastrectomy) for
peptic ulcer
20 years ago, who is admitted for epigastric pain and distension, frequent
vomiting
, asthenia and weight loss. Physical examination, barium meal and upper digestive endoscopy with biopsy established the diagnosis of carcinoma of the gastric stump, due to malignant transformation of adenomatous polyps, with duodenal invasion. Completion of gastrectomy and pancreaticoduodenectomy was performed, with good postoperative results. Although the extent of resection may appear excessive, our attitude was justified by the features of the lesion and good biological condition of the patient.

This retrospective study was conducted in order to determine the clinical and microbiologic features of infection with Salmonella enterica serotype Choleraesuis. Between March 1999 and December 2002, 55 patients with 66 isolates were enrolled for analysis. The ratio of males to females was 2.2:1. Most patients were older than 60 years (56%) and had underlying diseases (78%), such as diabetes mellitus, malignancy, and
peptic ulcer
. Fever (85%) was the most common clinical manifestation, followed by abdominal pain/fullness (31%). The gastrointestinal manifestations, including nausea/
vomiting
or diarrhea, accounted for only 13% and 11% of patients, respectively. S. enterica serotype Choleraesuis was extremely invasive, with a high predilection to cause bacteremia (78% of the isolates were from blood). Various types of metastatic focal infections were found, including infected arterial aneurysm, osteomyelitis, septic arthritis, urinary tract infection and wound infection. The crude mortality rate was 18% (10 deaths in 55 cases). Nearly all isolates were susceptible to the third-generation cephalosporins. A higher resistance rate to commonly used antimicrobial agents was found with ampicillin (85%, 56/66), trimethoprim-sulfamethoxazole (81%, 40/49), chloramphenicol (96%, 47/49), and ciprofloxacin (49%, 30/61). In view of the emergence of fluoroquinolone resistance, the third-generation cephalosporins appear to be the best choice for treatment of invasive infections caused by this organism.

When no organic cause for dyspepsia is found, the condition generally is considered to be functional, or idiopathic. Nonulcer dyspepsia can cause a variety of symptoms, including abdominal pain, bloating, nausea, and
vomiting
. Many patients with nonulcer dyspepsia have multiple somatic complaints, as well as symptoms of anxiety and depression. Extensive diagnostic testing is not recommended, except in patients with serious risk factors such as dysphagia, protracted
vomiting
, anorexia, melena, anemia, or a palpable mass. In these patients, endoscopy should be considered to exclude gastroesophageal reflux disease, peptic or duodenal ulcer, and gastric cancer. In patients without risk factors, consideration should be given to empiric therapy with a prokinetic agent (e.g., metoclopramide), an acid suppressant (histamine-H2 receptor antagonist), or an antimicrobial agent with activity against Helicobacter pylori. Treatment of patients with H. pylori infection and nonulcer dyspepsia (rather than
peptic ulcer
) is controversial and should be undertaken only when the pathogen has been identified. Psychotropic agents should be used in patients with comorbid anxiety or depression. Treatment of nonulcer dyspepsia can be challenging because of the need to balance medical management strategies with treatments for psychologic or functional disease.

Duodenogastric reflux (DGR) has been found to give rise to a hypochlorhydria secondary to alkaline reflux. We investigated whether there is a link between DGR and the gastrin, somatostatin, and serotonin cell numbers and the granular content of gastrin, somatostatin, and serotonin in endocrine cells in human antral mucosa. We investigated 38 selected Helicobacter pylori-negative patients with visual primary excessive DGR in upper endoscopy and symptoms of epigastric pain and bile
vomiting
. Ten control patients were included in this study. None of the patients had
peptic ulcer
or had received any medication. Antrum (10 biopsies from five different zones: the lesser and major curvature, the anterior and posterior wall, and the pylorus) and corpus (two biopsies from major curvature about 10 cm below the cardia) biopsy specimens were collected for routine histology, as well as for light and electron immunohistochemistry. In patients without atrophy or intestinal metaplasia and in patients with mild atrophy or mild intestinal metaplasia, the number of gastrin and somatostatin cells was not different from that in controls. In moderate atrophy or moderate intestinal metaplasia, however, the number of gastrin and somatostatin cells decreased. Serotonin cell number was significantly higher in all patients with DGR as compared with controls. The mean somatostatin granular content was increased (3.6+/-0.2 vs. 3.2+/-0.1). In addition, lysosomes with engulfed somatostatin granules were found. The mean serotonin granular content was decreased (2.3+/-0.3 vs. 2.9+/-0.3), while the mean gastrin granular content remained unchanged (2.5+/-0.3 vs. 2.4+/-0.2). Ultrastructurally, the granules in serotonin-positive cells corresponded to the gastric variant or to the intestinal variant of serotonin cells. The endocrine cells were found to have few granules positive for serotonin. It is concluded that DGR inhibits somatostatin granular release, but stimulates both serotonin granular release and serotonin cell growth.
