    Enteritis necroticans (EN), known as pigbel in Papua New Guinea (PNG), may be the important predisposing lesion to mid-gut volvulus, jejunal and ileal ileus and other forms of small bowel strangulation in communities where protein deprivation, poor food hygiene, epochal meat feasting and staple diets containing trypsin inhibitors co-exist. Such human habitats occur in Africa, Central and South America, western Pacific, Asian and south-east Asian cultures. Isolated outbreaks of necrotizing enteritis have been reported from Uganda, Malaysia and Indonesia but as yet no systematic epidemiological study of the prevalence of small bowel strangulations has been described in the surgical literature of 'third world' countries. Now that enteritis necroticans is preventable by vaccination, such studies should be undertaken. This paper outlines the story of pigbel and its control in PNG.

    A 71-year-old man with intestinal pseudo-obstruction was found to have a diffusely thickened adynamic small bowel with AA-amyloid in submucosal vessels and muscularis propria, foreign body giant cell reaction to amyloid, and necrotizing angiitis. The mucosa was unremarkable. Immunostains demonstrated numerous CD68+ monocyte/macrophages and CD8+ T cells associated with the amyloid deposits. The patient had no evidence of systemic vasculitis and no underlying cause for AA-amyloidosis was identified. Necrotizing angiitis coexistent with amyloid angiopathy has been reported in brain and temporal arteries, but not in the gastrointestinal tract and not with AA-amyloid. The inflammatory cell infiltrates in this case are consistent with a foreign-body and/or cell-mediated immunologic reaction to AA-amyloid, although a role for these cells in amyloid formation cannot be excluded.

    Since it was first described in 1978 the abdominal cocoon continues to be a rare cause of intestinal obstruction. So far this rare condition where the small intestine is encased in a fibrous membrane has been reported only in females. Diagnosis is usually made at laparotomy and the treatment of choice is lysis of adhesions. Proper recognition of this benign condition will result in the correct management of it and prevent unnecessary bowel resections. Five new cases including one male patient, together with a review of previous reports in the English literature, are presented.

    Two groups of goats were experimentally infected with Haemonchus contortus and Trichostrongylus colubriformis, and killed at various days after infection (DAI). The percentage of worms that established in the abomasum and the small intestine was low. At necropsy, abomasums from infected goats had thickened walls and oedematous folds. At 7 DAI there was an initial infiltration of eosinophils and some neutrophils which tend to increase with age of infection. The mean pH of the abomasum in goats infected with H. contortus was 5.43 (range 5.3-5.7), while that of the control goats was 3.30 (range 2.8-3.7).

    We describe a 50-year-old Chinese woman who had severe gastrointestinal manifestations from systemic sclerosis complicated by spontaneous pneumoperitoneum in the absence of either visceral perforation or pneumatosis cystoides intestinalis. This is a rare complication of systemic sclerosis; only four other cases have been reported. Recognition of this condition is important so as to avoid unnecessary surgery.

    Fistula formation following pelvic surgery and radiotherapy, including ureteric-arterial fistulas (UAF), is well documented, however, ureteric-arterial-enteric fistula is extremely rare. Conventional autopsy is usually required for the definitive diagnosis of pelvic vascular fistulas although an accurate diagnosis can still be complicated and challenging. The role of post-mortem computed tomography (PMCT) as an adjunct to conventional autopsy is well documented in the literature. One of the limitations of PMCT is the diagnosis of vascular conditions. Post-mortem computed tomography angiography (PMCTA) is a recently introduced technique that can assist in detecting such pathology. We present a case of post-radiotherapy ureteric-arterial-enteric fistula presenting as massive rectal and vaginal bleeding diagnosed prior to autopsy on PMCTA. The role of PMCTA in the diagnosis of such a UAF has not previously been reported in the literature.

    Although bleeding into the intestinal lumen may occur in strangulating intestinal obstruction, haematemesis is infrequently encountered. We report on a patient who presented with haematemesis and who had, in addition, clinical and radiological features of small bowel obstruction. Upper gastrointestinal endoscopy did not locate the source of bleeding. At laparotomy, which was performed because of clinical deterioration, gangrenous strangulated small bowel secondary to adhesive obstruction was found. In a patient with non-resolving intestinal obstruction, a deterioration in the condition is a clear indication for exploration. Haematemesis occurring concurrently may be a marker of intestinal strangulation, adds strength to the indication and highlights the urgency of the need for exploration.

    Psychosocial stress is reported to be one of the main causes of obesity. Based on observations in studies that relate stress and gut inflammation to obesity, the present study hypothesized that chronic stress, via inflammation, alters the expression of nutrient transporters and contributes to the development of metabolic syndrome. Rats were exposed to restraint stress for 4 h/day for 5 days/week for eight consecutive weeks. Different segments of rat intestine were then collected and analysed for signs of pathophysiological changes and the expression of Niemann-Pick C1-like-1 (NPC1L1), sodium-dependent glucose transporter-1 (SLC5A1, previously known as SGLT1) and facilitative glucose transporter-2 (SLC2A2, previously known as GLUT2). In a separate experiment, the total anti-oxidant activity (TAA)-time profile of control isolated intestinal segments was measured. Stress decreased the expression of NPC1L1 in the ileum and upregulated SLC5A1 in both the jejunum and ileum and SLC2A2 in the duodenum. Inflammation and morphological changes were observed in the proximal region of the intestine of stressed animals. Compared with jejunal and ileal segments, the rate of increase in TAA was higher in the duodenum, indicating that the segment contained less anti-oxidants; anti-oxidants may function to protect the tissues. In conclusion, stress alters the expression of hexose and lipid transporters in the gut. The site-specific increase in the expression of SLC5A1 and SLC2A2 may be correlated with pathological changes in the intestine. The ileum may be protected, in part, by gut anti-oxidants. Collectively, the data suggest that apart from causing inflammation, chronic stress may promote sugar uptake and contribute to hyperglycaemia.

    The effect of soy protein on the small bowel mucosa of 18 infants with acute gastroenteritis was studied. The infants were maintained on a protein hydrolysate formula for 6-8 weeks, following which they were readmitted for soy protein challenge studies. Jejunal biopsy was performed before and 24 h after challenge. On the basis of the clinical and histological reaction to soy protein challenge, three groups were identified. Group 1 consisted of three infants who had clinical and histological reaction. There was associated depletion of mucosal enzymes, lactase, sucrase, malatase, alkaline phosphatase, and blood xylose levels. Group 2 consisted of seven infants who had histological reaction but no clinical symptoms. Two of these seven infants, however, developed clinical reaction when rechallenged with soy protein 2 and 90 days later. Following challenge, mucosal enzymes and blood xylose levels were depressed in five of the seven infants tested. Group 3 consisted of eight infants who did not have either a clinical or a histological reaction. The mucosal enzymes and blood xylose levels were not depressed in four infants tested. The present study shows that the small bowel mucosa of some young infants recovering from acute gastroenteritis remains sensitive to soy protein for a variable period of time. The feeding of soy protein to these infants may result in the persistence of mucosal damage and perpetuation of diarrhea.(ABSTRACT TRUNCATED AT 250 WORDS)

    Coeliac disease (CD) is an inflammatory disorder of the small intestine. It includes aberrant adaptive immunity with presentation of CD toxic gluten peptides by HLA-DQ2 or DQ8 molecules to gluten-sensitive T cells. A ω-gliadin/C-hordein peptide (QPFPQPEQPFPW) and a rye-derived secalin peptide (QPFPQPQQPIPQ) were proposed to be toxic in CD, as they yielded positive responses when assessed with peripheral blood T-cell clones derived from individuals with CD. We sought to assess the immunogenicity of the candidate peptides using gluten-sensitive T-cell lines obtained from CD small intestinal biopsies. We also sought to investigate the potential cross-reactivity of wheat gluten-sensitive T-cell lines with peptic-tryptic digested barley hordein (PTH) and rye secalin (PTS). Synthesised candidate peptides were deamidated with tissue transglutaminase (tTG). Gluten-sensitive T-cell lines were generated by culturing small intestinal biopsies from CD patients with peptic-tryptic gluten (PTG), PTH or PTS, along with autologous PBMCs for antigen presentation. The stimulation indices were determined by measuring the relative cellular proliferation via incorporation of (3) H-thymidine. The majority of T-cell lines reacted to the peptides studied. There was also cross-reactivity between wheat gluten-sensitive T-cell lines and the hordein, gliadin and secalin peptides. PTH, PTS, barley hordein and rye secalin-derived CD antigen-sensitive T-cell lines showed positive stimulation with PTG. ω-gliadin/C-hordein peptide and rye-derived peptide are immunogenic to gluten-sensitive T-cell lines and potentially present in wheat, rye and barley. Additional CD toxic peptides may be shared.

    OBJECTIVE: To report a case of enteritis necroticans acquired in Australia, and to review the history, epidemiology, pathogenesis, clinical features, management and prevention of this disease.

    CLINICAL FEATURES: A 44-year-old diabetic and alcoholic restaurateur of Chinese-Malay origin, who had been living in Australia for over 20 years, was admitted to hospital with bloody diarrhoea which progressed to fulminant toxaemia and circulatory collapse, and ultimately required laparotomy. Typical pathological features and the isolation of Clostridium perfringens type C from faeces confirmed the diagnosis of enteritis necroticans.

    INTERVENTION AND OUTCOME: He was treated initially with ampicillin, gentamicin, metronidazole and chloramphenicol, and later with penicillin and metronidazole, and he required large volumes of intravenously administered fluid and blood for his toxaemic, hypotensive state. Laparotomy was performed as a life-saving procedure. Despite a lengthy convalescence, the patient recovered.

    CONCLUSIONS: Enteritis necroticans is a rare disease in developed countries, however it is likely to be underdiagnosed. Clinicians are encouraged to be on the alert for signs of severity that may indicate the need for laparotomy in a predisposed individual with features of this condition.

    A 37-year-old Chinese male presented with an acute abdomen. Surgical exploration revealed duodenal perforation, extensive small bowel infarction and peritonitis. Histopathology of the resected bowel showed characteristic features of classic polyarteritis nodosa. The latter also involved mesenteric arteries in the form of tiny aneurysms. Steroids could not be started due to: (i) overwhelming microbial infections and (ii) fear of more perforations in other areas of the bowel. Such a presentation of polyarteritis nodosa is uncommon. Its recognition prior to surgery, management and prognosis is discussed.

    INTRODUCTION: The Northeastern region of Peninsular Malaysia is an area with exceptionally low prevalence for Helicobacter pylori infection. The risk of intestinal metaplasia and dysplasia in patients with chronic atrophic gastritis (CAG) and its association with Helicobacter pylori is unknown in this region.

    METHODS: This was a cross-sectional study on gastric biopsies from 234 consecutive patients (mean age 53.5 [14.8] years) who underwent upper gastrointestinal endoscopy between January 2006 and December 2006.

    RESULTS: There were 137 (59%) men and 185 (79%) Malay patients. Among 234 biopsies, CAG was found in 99 and non-atrophic gastritis in 135. Intestinal metaplasia and dysplasia were detected in 8 and 6 atrophic gastritis biopsies, respectively, and in 10 and 3 of non-atrophic gastritis biopsies, respectively. H. pylori were detected in 16 (9 Malays, 7 non- Malays) biopsies (p=0.024); intestinal metaplasia was detected in 4 biopsies (p=0.3) and dysplasia in 5 biopsies (p=0.3). Of the 218 biopsies negative for H. pylori, intestinal metaplasia was found in 14 and dysplasia in 4. The risk of intestinal metaplasia as well as dysplasia was associated with presence of H. pylori infection (p=0.029 and p<0.001 respectively).

    CONCLUSION: Even in a setting of low prevalence of H. pylori, intestinal metaplasia and dysplasia were significantly associated with H. pylori infection. The frequency of intestinal metaplasia and dysplasia was similar different between biopsies with atrophic gastritis and non-atrophic gastritis.
