Radiological evidence of presence of air or gas within the stomach wall is termed "gastric pneumatosis" and is considered an ominous sign. However, the etiological associations range from benign self-limiting causes to life-threatening emergencies. The authors report the case of gastric pneumatosis in a 34-year-old man who presented to the emergency(More)
Background. In patients with benign biliary strictures, the use of fully covered self-expandable metal stents (SEMS) has been proposed as an alternative to plastic stenting, but high quality prospective data are sparse. This study was performed to evaluate the long-term effectiveness and safety of a new fully covered SEMS for benign biliary strictures.(More)
Short-wire endoscopic retrograde cholangiopancreatography (ERCP) systems are perceived to carry advantage over traditional long-wire devices. To date, this potential advantage has not been well documented, and gastroenterologists are confronted in everyday practice with the dilemma of choosing a particular system without the benefit of having objective(More)
AIM To examine the relationship between H. pylori and gastro-oesophageal reflux disease (GORD) in Iran. METHODS In this study 51 GORD patients (referred to endoscopy at Taleghani hospital) were compared with 49 age-sex matched controls. Diagnosis of H. pylori was made by gastric mucosal biopsy and rapid urease test (positive if the result of one or both(More)
Identifying risk factors for advanced colorectal adenomas may aid in colorectal cancer (CRC) screening, especially in light of the American College of Gastroenterology’s recent guidelines, emphasizing cancer prevention through identification and removal of advanced adenomas. Smoking is an important risk factor for advanced adenomas but there is little data(More)
BACKGROUND Diagnosis of a foregut duplication cyst is of great clinical impact. A definitive diagnosis of a foregut duplication cyst can avert the need for major thoracic surgery in the otherwise asymptomatic individual. This study sought to evaluate the safety and the utility of EUS and EUS-guided FNA (EUS-FNA) in the diagnosis of foregut duplication(More)
OBJECTIVES It is widely believed that sphincter of Oddi dysfunction (SOD) induces pancreatitis through an increase in intrapancreatic ductal pressure. Animal models have demonstrated that increased intrapancreatic ductal pressure plays a role in the development of pancreatitis. The role of intrapancreatic ductal pressure in SOD-induced pancreatitis has not(More)
Four methods for isolation of Yersinia enterocolitica from raw and pasteurized milk from northern Iran were compared. Three hundred and ten raw milk samples were collected from tanks on their arrival at various central dairies, and 40 pasteurized milk samples were collected from tanks on their arrival at a manufacturing plant. Each sample was examined for(More)
Second harmonic generation (SHG) is a novel imaging technology that could provide optical biopsy during endoscopy with advantages over current technology. SHG has the unique ability to evaluate the amount of extracellular matrix collagen protein and its alignment. Hematoxylin- and eosin-stained slides from colon biopsies (normal, low-grade dysplasia (LGD),(More)
A simple reproducible and sensitive prognostic trauma tool is still needed. In this article we have introduced modified GCS motor response (MGMR) and evaluated the performance of logistic models based on this variable. The records of 8452 trauma patients admitted to major hospitals of Tehran from 1999 to 2000 were analysed. 7226 records with known outcome(More)
