Inflammation of the gastric and duodenal mucosa is the end result of an imbalance between mucosal defensive and aggressive factors. The degree of inflammation and imbalance between defensive and aggressive factors can then result in varying degrees of gastritis and/or mucosal ulceration. Gastritis and ulcers of the duodenum or stomach can be classified as primary or secondary. The majority of children with chronic gastritis and ulcers in the stomach or duodenum have secondary inflammation or mucosal ulceration. These secondary ulcers generally occur due to a systemic condition like head trauma or overwhelming sepsis, or as sequelae to drug ingestion (i.e. non-steroidal anti-inflammatory agents), but secondary gastroduodenal ulcers can also occur in specific disease conditions such as Zollinger-Ellison syndrome or Crohn's disease. In almost all children with primary duodenal or gastric ulcers mucosal inflammation and, less frequently, ulceration is caused by a spiral shaped, gram-negative, microaerobic rod Helicobacter pylori. Recent epidemiological evidence has linked chronic H. pylori infection with the development of gastric carcinomas.

Vertical banded gastroplasty, reported by Mason in 1982, is an effective method to control pathologic obesity (BMI>40 kg/m2). With the widespread of this procedure and the introduction of laparoscopic approach several complications are described in literature: gastroesophageal reflux, esophagitis, gastritis, gastric bleeding and perforations, prolonged vomit, dislocation of gastric ring, cholelithiasis, gastric fistulas, gastric stomal stenosis, dehiscence of vertical stomach staple line. From 2 to 10% of patients are reoperated because of inefficacy of treatment or short and long-term complications. Morbidity and mortality associated to reoperations are still high and it is difficult to identify criteria for an appropriate revision procedure. This can occur through endoscopy, laparotomy or laparoscopy, depending on clinical and radiologic feature. Dehiscence of vertical stomach staple line, observed in 10-20% of cases, even if asymptomatic, can lead to bad complications such as fistulas, peritonitis and sepsis. The case of a young woman, who underwent a vertical banded gastroplasty for pathologic obesity (117 kg, h 167 cm, BMI 42/m2) and subsequent laparotomies in the attempt to correct vertical staple line dehiscence, is reported. The patient came to our observation in a septic shock caused by peritonitis and ARDS and a total gastrectomy with Roux-en-Y esophago-jejunostomy was performed.

During the last decade several new Helicobacter species have been isolated from human gastric mucosa, fecal samples, liver, and gallbladder. Gastric corkscrew-shaped Helicobacter species: H. heilmannii is usually seen in the gastric foveolae in 0.2-0.6% of histological sections from the gastric mucosa of patients with dyspepsia in Western Europe, but it has only been cultured once. It is genetically and morphologically closely related to H. bizzozeronii and H. salmonis which are common in dogs and cats. It causes constantly active chronic gastritis and is regularly associated with peptic ulcer. Intestinal Helicobacter species: H. cinaedi, H. fennelliae, H. pullorum, H. westmeadii, H. canadensis, and 'H. rappini' have been isolated from patients with enteritis and proctitis. H. fennelliae, H. cinaedi, H. westmeadii, and 'H. rappini' have been isolated also from patients with septicemia. Studies indicate that H. cinaedi is transmitted from hamsters and that H. pullorum is common in chickens. 'H. rappini' has been isolated from sheep, dogs, and mice, whereas no animal reservoir has been found for H. fennelliae. Except for the cases of septicemia, none of these Helicobacter species have yet been proven to cause human disease, but they are suspected to play a role in inflammatory bowel diseases. Hepatobiliary Helicobacter species include several Helicobacter species isolated from bile and liver of animals, but only H. bilis has been isolated from the human gallbladder and H. pylori from the human liver. H. bilis has been isolated from dogs, cats, mice, and rats. Nonpylori Helicobacter species are usually difficult to culture and may be more frequently causes of human disease than realized today.

Associated abnormalities of other organ systems result in considerable long-term morbidity in patients of prune-belly syndrome (PBS). The gastrointestinal anomalies commonly observed with PBS are persistence of the embryonic wide mesentery and absence of fixation to the posterior abdominal wall, whereas anorectal malformations (ARM) are rarely associated with PBS. We describe one such case of PBS associated with high ARM and urethral stenosis in a one-day-old male newborn. The neonate underwent preliminary sigmoid colostomy for ARM, but he subsequently developed necrotizing gastritis and gastric perforation in the postoperative period and had to undergo partial gastrectomy and vesicostomy. The neonate developed fatal septicemia after second surgery. A review of all the reported cases of this association is presented and the dilemmas in the management of these cases are discussed.

The normal indigenous intestinal microflora consists of about 10(15) bacteria that under physiological conditions reside mainly in the lower gastrointestinal tract. Bacterial overgrowth implies abnormal bacterial colonization of the upper gut, resulting from failure of specific defense mechanisms restricting colonization under physiological conditions. At present two types of bacterial overgrowth with defined pathogenesis can be distinguished: (1) gastric overgrowth with upper respiratory tract microflora resulting from selective failure of the gastric acid barrier, and (2) gastrointestinal overgrowth with Gram-negative bacilli (enteric bacteria) resulting from failure of intestinal clearance. Helicobacter pylori-induced gastritis of the oxyntic mucosa is the main cause of acquired failure of the gastric acid barrier, which is common among the healthy elderly. Intestinal clearance may fail as the result of impaired intestinal peristalsis or anatomical abnormalities that alter luminal flow. Impaired peristalsis is associated with conditions interfering with intestinal neuromuscular function including myopathic, neuropathic, autoimmune, infectious, inflammatory, metabolic, endocrine, and neoplastic diseases. Anatomical abnormalities are mainly the result of gastrointestinal surgery, intestinal diverticula or fistula. Combined failure of intestinal clearance and the gastric acid barrier results in more severe colonization with Gram-negative bacilli. Gram-negative bacilli are uncommon in the upper gut of otherwise healthy individuals with gastric hypochlorhydria, being acquired (H. pylori) or drug-induced. Significant bacterial overgrowth with Gram-negative bacilli is a rational in the search for an explanation to optimize clinical management. The clinical significance of colonization with upper respiratory tract microflora remains unclear. Translocation of live bacteria, their metabolic products, or antigens from a small bowel colonized by Gram-negative bacilli play a role in the pathogenesis of spontaneous bacterial peritonitis in hepatic disease and in certain types of sepsis, indicating that further studies can point to new patient populations with potential benefit from medical treatment.

A 64-year-old male with an APC resistance (factor V mutation Leiden) and interrupted oral anticoagulation due to an erosive gastritis, was admitted to hospital for increasing dyspnoea. Transthoracic echocardiography revealed a floating thrombus via an open foramen ovale in both atria reaching both ventricles. Sonography showed multiple stage thrombosis of the left leg reaching to the V. femoralis superficialis. A few months previously, peripheral pulmonary artery embolization has been confirmed by scintigraphy. The patient was transferred to our hospital and underwent emergency surgery for closure of the atrial septum defect and thrombus removal. On the 4th postoperative day, the patient was transferred to the normal ward, however, on the 10th postoperative day, the patient developed a symptomatic transitory psychotic syndrome and became hypotensive before he was transferred to the ICU. Due to impaired oxygenation and the patient's history, a new pulmonary artery embolization was suspected. After ICU admission, the patient required increasing norepinephrine support and rapidly developed septic fever. However, serum procalcitonin was elevated and a computed tomography (skull, chest and abdomen) was performed for a focus search. Pulmonary artery embolism could be ruled out but an oval structure near to the ampulla recti (ca. 30 x 20 mm) was identified as an abscess and immediate abscess incision was performed. After surgery, the further course was characterized by a steep fall in vasopressor support and body temperature. The patient was transferred to the normal ward on the 2nd postoperative day. This case shows that procalcitonin allows early and reliable diagnosis of sepsis in patients with undefined shock.

The introduction of mycophenolate as an adjuvant in immunosuppressive regimes has improved clinical outcomes of transplant patients due to a reduced incidence of acute rejection episodes. Nevertheless, the need for dose adjustments or therapy discontinuations (up to 45% in some series), have downgraded the efficacy of mycophenolate mofetil (MMF). From October 2003 to April 2005, 36 kidney transplantations were performed at our site. The immunosuppressive protocol included induction with basiliximab, administered on days 0 and 4 posttransplantation, cyclosporine microemulsion (CsA-ME) monitored by concentrations at 2 hours (C2), enteric-coated sodium mycophenolate (EC-MPS; 720 +/- 180 mg bid), and steroids. Mean follow-up time was 7.3 +/- 4.4 months. Fourteen patients (38.9%) experienced delayed graft function (DGF). Seven (19%) episodes of acute rejection included 5 graded as I-A, 1 as grade I-B, and 1 as grade II-A. There were discontinuations of EC-MPS. Regarding gastrointestinal (GI) adverse events, there were 2 episodes of noninfectious diarrhea, 1 gastritis, and 1 upper GI hemorrhage. There were 11 infections: 4 in the urinary tract; 3 in the lung; 3 in the GI tract; and 1 CMV infection. There were no discontinuations of EC-MPS reported [corrected] Two (6%) graft losses were reported to be due to sepsis. In this group of patients who experienced a high incidence of DGF, the combination of basiliximab, CsA-ME (monitored by C2), and EC-MPS resulted in low Banff grade acute rejection episodes which were all responsive to steroids. The incidence of GI adverse events was only 11%.

A Meckel diverticulum is an embryonic remnant of the vitellointestinal duct. It is present in approximately 2% of the population and is estimated to cause symptoms<5% of the time. It generally results in painless bleeding or abdominal pain. Rarely, it can rupture, resulting in peritonitis and gram-negative sepsis. We present the case of a 17-year-old male who ruptured his Meckel diverticulum 23 days after the beginning of induction chemotherapy for high-risk acute lymphoblastic leukemia. We postulate that gastritis caused by dexamethasone, mucositis caused by doxorubicin, and the unique anatomic nature of a Meckel diverticulum may have contributed to this extremely unlikely and previously unreported event.

Clostridium perfringens sepsis following orthotopic liver transplantation (OLT) is a rare but reported complication that historically results in mortality or emergent retransplantation (ReTx). Complications from C. perfringens emphysematous gastritis have contributed to the death of a healthy live liver donor as well. Herein, we describe the first documented survivor of C. perfringens sepsis following OLT managed without laparotomy or emergent ReTx.

Juvenile seals are sometimes encountered in waters around South Australia with injuries and/or diseases that require veterinary treatment. Two cases are reported where apparently stable animals died soon after being rescued due to quite disparate conditions. In Case 1 a juvenile male New Zealand fur seal (Arctocephalus forsteri) was found unexpectedly dead in its enclosure. A necropsy examination revealed an emaciated juvenile male with no injuries. The intestine was filled throughout its length with melena stool that was due to heavy infestation of the stomach with roundworms with adjacent gastritis. Death was due to shock from upper gastrointestinal blood loss secondary to parasitosis. In Case 2 a second juvenile male New Zealand fur seal (Arctocephalus forsteri) also died unexpectedly in its enclosure. It had been listless with loud respirations since capture. At necropsy there was no blood around the head, neck or mouth, and no acute external injuries were identified. An area of induration was, however, present over the snout with fragmentation of underlying bones. The maxilla was freely mobile and CT scanning revealed multiple comminuted fractures of the adjacent facial skeleton. Examination of the defleshed skull showed fragmentation of the facial skeleton with roughening of bones in keeping with osteomyelitis. Death was attributed to sepsis from osteomyelitis of a comminuted midfacial fracture. These cases demonstrate two unusual and occult conditions that may be present in recently retrieved juvenile fur seals. Failure to establish the correct diagnosis rapidly may result in death soon after capture. The usefulness of imaging techniques such as CT scanning in delineating underlying injuries prior to necropsy is clearly demonstrated.
