Circulating Bone Marrow-Derived CD45-/CD34+/CD133+/VEGF+ Endothelial Progenitor Cells in Adults with Crohn's Disease.

Background: Circulating endothelial progenitor cells (EPCs) are bone marrow-derived stem cells able to migrate to sites of damaged endothelium and differentiate into endothelial cells. Altered EPC level and function have been described in various inflammatory diseases and have been shown to augment vasculogenesis in murine models. Previous studies of EPC in the context of Crohn's disease (CD) have yielded conflicting results.

Trends in secondary antibiotic resistance of Helicobacter pylori from 2007 to 2014: has the tide turned?

The current guidelines recommend culture and antibiotic susceptibility testing of Helicobacter pylori following two failed eradication attempts. Where testing is unavailable, epidemiological data for secondary H. pylori resistance are essential to allow for the rational use of antibiotics.

Valproic acid-induced eosinophilic pleural effusion: a case report and review of the literature.

We present a case of eosinophilic pleural effusion due to valproic acid (VPA), a rare adverse event that has been reported previously. A 30-year-old male patient presented with respiratory symptoms and right-sided pleuritic pain, within days of initiation of VPA treatment for a generalized seizure. Chest radiography revealed a moderate-sized right-sided pleural effusion, which was an exudate with a pH of 7.
