Surgical Excision of a Laimer's Diverticulum: A Case Report and Review of the Literature.

A pharyngoesophageal diverticulum (PED) is a rare clinical entity. This paper reports on a 79-year-old male patient with PED and symptoms of dysphagia, regurgitation and chronic cough. The diverticulum was located on the dorsal side of the cervical esophagus, midline, inferior to the cricopharyngeal muscle.

The Inflammatory Bowel Disease-Disk Tool for Assessing Disability in Inflammatory Bowel Disease Patients: Validation of the Greek Version.

Background: The Inflammatory Bowel Disease-Disk (IBD-Disk) is a physician-administered tool that evaluates the functional status of patients with Inflammatory Bowel Disease (IBD). The aim of our study was to validate the content of the IBD-Disk in a Greek cohort of IBD patients.

Methods: Two questionnaires [the IBD Disk and the IBD-Disability Index (IBD-DI)] were translated into Greek and administered to IBD patients at baseline visit, after 4 weeks and 6 months.

The burden and management of anemia in Greek patients with inflammatory bowel disease: a retrospective, multicenter, observational study.

Background: Anemia is a common extraintestinal manifestation of Inflammatory Bowel Disease (IBD) affecting negatively the patients' quality of life. The aim of this study was to determine the frequency and real-life management of anemia in IBD patients in Greece.

Methods: This study was conducted in 17 Greek IBD referral centers.

Simultaneous occurrence of hyperthyroidism and fistulizing Crohn's disease complicated with intra-abdominal fistulas and abscess: a case report and review of the literature.

Introduction: Fistula formation in patients with Crohn's disease is a common complication during the course of the disease. Perianal and enteroenteric are the most common forms of fistulas, whereas the involvement of the upper gastrointestinal tract with gastrocolic and duodenocolic fistulas represents an extremely unusual condition. Moreover, hyperthyroidism in association with Crohn's disease has been rarely described.

Early viraemia clearance during antiviral therapy of chronic hepatitis C improves dendritic cell functions.

Plasma and cellular HCV RNA and core antigen were tested in monocyte-derived DC (MDDC) from chronic hepatitis C patients undergoing treatment with peg-interferon alpha2b/ribavirin. DC allostimulatory capacity, HCV-specific T-cell reactivity and IL-12 production were measured at baseline and treatment week (TW)12. Using DC and autologous CD4(+)T-cells, obtained at baseline and TW12, we performed cross-over experiments to determine the relative role of DC and/or T-cells for impaired immune reactivity to HCV.

Co-existence of a giant splenic hemangioma and multiple hepatic hemangiomas and the potential association with the use of oral contraceptives: a case report.

Introduction: Hepatic and splenic hemangiomas are common benign tumors that mainly affect female patients. Giant splenic hemangiomas are extremely rare, especially when correlated with multiple hepatic hemangiomas. Pathogenetic mechanisms between hemangiomas and oral contraceptives, as well as therapeutic approaches, are analyzed in this case report, in particular for the management of synchronous splenic and hepatic hemangiomas.

Mirizzi syndrome type IV associated with cholecystocolic fistula: a very rare condition--report of a case.

Background: Mirizzi syndrome is a rare complication of prolonged cholelithiasis with presence of large, impacted gallstone into the Hartman's pouch, causing chronic extrinsic compression of common bile duct (CBD). Fistula formation between the CBD and the gallbladder may represent an outcome of that condition. According to Mirizzi's classification and Csendes's subclassification, Mirizzi syndrome type IV represents the most uncommon type (4%).

Is hepatitis C virus infection of dendritic cells a mechanism facilitating viral persistence?

More than 170 million people worldwide are chronically infected with hepatitis C virus (HCV), which is a major cause of chronic hepatitis, cirrhosis, and hepatocellular carcinoma. Impaired T-cell reactivity to HCV, a hallmark of inefficient adaptive immunity, is believed to be responsible for the high propensity of HCV to cause chronic infection. Dendritic cells are the most potent antigen-presenting cells and many viruses affect various dendritic cell functions.

'Nipped in the Budd': hepatic venous outflow obstruction in evolution.

Hepatic venous thrombosis (Budd-Chiari) in evolution is a rare phenomenon and carries a high morbidity and mortality. We describe the case of a 39-year-old Bangladeshi lady who presented with severe abdominal pain secondary to a perforated duodenal ulcer and during her hospital admission developed an asymptomatic Budd-Chiari syndrome (BCS). Our report highlights the important role of an inflammatory focus, and how this process with an associated reactive thrombocytosis may act as a trigger for the development of BCS in an individual with predisposing risk factors.
