Gastrointestinal ischemia/reperfusion (IR) injury significantly contributes to the morbidity and mortality of critical illness. In this study, we hypothesized a protective role for extracellular adenosine signaling in intestinal IR injury. Initial profiling studies of mucosal scrapings following murine IR demonstrated selective induction of the A2B adenosine receptor (A2BAR) transcript. Moreove...

This study represents our experience with severe blunt gastrointestinal injury in 29 polytrauma and 3 solitary trauma patients. The primary diagnosis was missed in intestinal perforation (4x) and mesenteric disrupture (1x). In 2 other patients contusion of the gastrointestinal wall led to postprimary perforation. The average mortality was 21.8%; only 2 patients died from abdominal sepsis. Blunt...

Treatment of cancer involves a multidisciplinary approach consisting of surgery, chemotherapy, molecular targeted therapy and radiation therapy. These therapies work on the tumor cells to result in cell stasis or cell death. The same mechanism can result in toxicity to the normal gastrointestinal tract. Radiation therapy can cause acute and chronic injury. The chronic injury results from involv...

Exacerbation of hypoxic injury after reoxygenation is a crucial mechanism mediating organ injury in transplantation, and in myocardial, hepatic, gastrointestinal, cerebral, renal, and other ischemic syndromes. The occlusion and reperfusion of the splanchnic artery is a useful animal model to elucidate the mechanism of gastrointestinal injury induced by ischemia-reperfusion (I/R). Although xanth...

background: critically ill children admitted to pediatric intensive care unit (picu) are at increased risk of gastrointestinal bleeding due to stress related mucosal injury. reducing gastric acid by acid suppressant medication is the accepted prophylaxis treatment, but there is not any definitive guideline for using prophylaxis in picu patients. the present study aimed to assess the effect of p...

Severe caustic injury to the gastrointestinal tract carries a high risk of luminal strictures. The aim of this retrospective study was to identify predicting factors for progress of caustic injury to gastric outlet obstruction (GOO) and esophageal strictures (ES), using modified endoscopic mucosal injury grading scale. We retrospectively reviewed medical records of patients with caustic injurie...

OBJECTIVE To determine the pattern, presentation and outcome of gastrointestinal injuries from blunt abdominal trauma in children. DESIGN A retrospective study. SETTING Ahmadu Bello University Teaching Hospital, Zaria, Nigeria. SUBJECTS Twenty one children managed for gastrointestinal injuries from blunt trauma from 1984-2002. MAIN OUTCOME MEASURES The pattern, presentation, management ...

NSAIDs are widely prescribed for the treatment of pain and inflammation and is well accepted and recommended by World Health Organization (WHO), but their use is associated with adverse gastrointestinal effects, ranging from dyspeptic symptoms and peptic ulcers to more serious complications. Elderly patients are at high risk of experiencing NSAID-induced gastrointestinal tract injury and should...

Complement activation plays an important role in local and remote tissue injury associated with gastrointestinal ischemia-reperfusion (GI/R). The role of the classical and lectin complement pathways in GI/R injury was evaluated using C1q-deficient (C1q KO), MBL-A/C-deficient (MBL-null), complement factor 2- and factor B-deficient (C2/fB KO), and wild-type (WT) mice. Gastrointestinal ischemia (2...
