Ulnar infected pseudoaneurysm in the course of extended-spectrum beta-lactamase septicemia.

We describe the first case of proximal ulnar pseudoaneurysm due to extended-spectrum beta-lactamase-producing . We performed an open ligation of the ulnar artery and partial excision of the aneurysmal sac. This article discusses the etiology and surgical management of ulnar-infected pseudoaneurysms according to the literature data.

The mononuclear phagocyte system contributes to fibrosis in post-transplant obliterans bronchiolitis.

Bronchiolitis obliterans syndrome (BOS) is a fibrotic disease that is heavily responsible for the high mortality rates after lung transplantation. Myofibroblasts are primary effectors of this fibrotic process, but their origin is still debated. The purpose of this work was to identify the precursors of mesenchymal cells responsible for post-transplant airway fibro-obliteration.
