Patients with IBD have higher prevalence, severity and extent of periodontitis compared with those having no IBD.

Bouveret's syndrome is a rare cause of gastric outlet obstruction. Its diagnosis is often delayed or overlooked. It is characterized by the passage of a large gall bladder stone through a bilio-duodenal fistula, which becomes lodged in the duodenum causing duodenal obstruction. We report the case of a 70-year-old male with a history suggestive of gall bladder disease over a 1-year period. The diagnosis was confirmed by ultrasound, which showed a single large gall bladder stone and the patient was planned for elective laparoscopic cholecystectomy. One week prior to the elective surgery he presented with upper gastrointestinal bleeding for which he was admitted, diagnosed by a gastroenterologist as bleeding duodenal ulcer and treated by local epinephrine injection and blood transfusion. One week later he presented with a picture of acute gastric outlet obstruction, which proved by endoscopy to be due to a large stone impacted in the duodenum. Endoscopic management failed and the stone was managed by open surgery. The patient made a good postoperative recovery and for the last year he has remained free of symptoms.

Although there is a high support among doctors for the promotion of EBM, there is a deficit in knowledge and skills of EBM. Hence, the time appears ripe for planning and implementing an effective EBM educational programme for both undergraduate and postgraduate doctors.

AIM:To estimate the prevalence of celiac disease (CD) in adult patients with presumed irritable bowel syndrome (IBS). METHODS:Between March 2005 and December 2008, 742 consecutive patients (293 male, median age 43 years, range 18-69 years) fulfilling the Rome Ⅱ criteria for IBS were prospectively enrolled in the study. IBS was diagnosed via self-completed Rome Ⅱ modular questionnaires. Anti-tissue transglutaminase (anti-tTG) serology was checked to initially recognize possible CD cases. Patients with a positive test were offered endoscopic duodenal biopsy to confirm the diagnosis of CD. RESULTS:Thirty two patients (15 male, median age 41 years, range 19-59 years) were found to have organic diseases other than CD. Twenty four patients tested positive for anti-tTG antibodies, and duodenal biopsies confirmed the diagnosis in all of them. Thus, in this patient population with presumed IBS, 3.23% actually had CD. CONCLUSION:CD is common in patients with presumed IBS. Routine screening for CD in patients with symptoms of IBS is recommended.

In spite of the positive attitude towards EBM, this study demonstrated numerous personal, interpersonal and institutional barriers towards implementing EBM which necessitate prompt action to formulate a national plan to overcome such barriers.

Endoscopic biliary stenting is a well-recognised method of palliation of malignant biliary obstruction. Distal stent migration causing duodenal perforation is an uncommon complication of this procedure and is usually delayed. Early stent migration resulting in duodenal perforation is extremely rare and can be easily overlooked. We present a case of stent migration and resultant intraperitoneal duodenal perforation that occurred 24 hours following plastic stent insertion for a malignant biliary stricture in a 63-year-old woman. The patient required emergent abdominal laparoscopy with the placement of intraperitoneal drain, followed by endoscopic extraction of the stent and closure of the defect using a through-the-scope clip. This case report addresses intraperitoneal duodenal perforation secondary to early migration of biliary stents. Special emphasis is placed on the importance of prompt diagnosis and the use of endoclips in the management of this serious complication of endoprosthesis.

AIMTo investigate the putative role of protozoan parasites in the development of irritable bowel syndrome (IBS).METHODSThe study included 109 IBS consecutive adult patients fulfilling the Rome III criteria and 100 healthy control subjects. All study subjects filled a structured questionnaire, which covered demographic information and clinical data. Fresh stool samples were collected from patients and control subjects and processed within less than 2 h of collection. Iodine wet mounts and Trichrome stained smears prepared from fresh stool and sediment concentrate were microscopically examined for parasites. Blastocystis DNA was detected by polymerase chain reaction, and Cryptosporidium antigens were detected by ELISA.RESULTSA total of 109 IBS patients (31 males, 78 females) with a mean age ± SD of 27.25 ± 11.58 years (range: 16 -60 years) were enrolled in the study. The main IBS subtype based on the symptoms of these patients was constipation-predominant (88.7% of patients). A hundred healthy subjects (30 males, 70 females) with a mean ± SD age of 25.0 ± 9.13 years (range 18-66 years) were recruited as controls. In the IBS patients, Blastocystis DNA was detected in 25.7%, Cryptosporidium oocysts were observed in 9.2%, and Giardia cysts were observed in 11%. In the control subjects, Blastocystis, Cryptosporidium and Giardia were detected in 9%, 0%, and 1%, respectively. The difference in the presence of Blastocystis (P = 0.0034), Cryptosporidium (P = 0.0003), and Giardia (P = 0.0029) between IBS patients and controls was statistically significant by all methods used in this study.CONCLUSIONPrevalence of Blastocystis, Cryptosporidium and Giardia is higher in IBS patients than in controls. These parasites are likely to have a role in the pathogenesis of IBS.
