Hemodialysis vascular graft as a focus of persistent Q fever.

Vascular access infection is a frequent complication in hemodialysis patients. We report the second case worldwide of a prosthetic hemodialysis vascular graft infection by Coxiella burnetii, with intense hypermetabolism on PET-CT, Q fever serology consistent with persistent infection, and positive C. burnetii DNA in the blood and removed vascular graft.

A 62-Year-Old Woman With Acute Respiratory Failure and a Painful Right Lower Limb.

A 62-year-old woman with no medical history was admitted to the ED for fever, acute respiratory failure, and pain in the right lower limb. Three months prior to presentation, she had spent 45 days travelling through India and Thailand. She presented with no signs of traveler's disease such as fever or diarrhea during that trip.

In Vivo Evaluation and Imaging of a Bilayered Self-Assembled Skin Substitute Using a Decellularized Dermal Matrix Grafted on Mice.

As time to final coverage is the essence for better survival outcome in severely burned patients, we have continuously strived to reduce the duration for the preparation of our bilayered self-assembled skin substitutes (SASS). These SASS produced in vitro by the self-assembly approach have a structure and functionality very similar to native skin. Recently, we have shown that a decellularized dermal matrix preproduced by the self-assembly approach could be used as a template to further obtain self-assembled skin substitute using a decellularized dermal template (SASS-DM) in vitro.

Tissue-engineered vascular adventitia with vasa vasorum improves graft integration and vascularization through inosculation.

Tissue-engineered blood vessel is one of the most promising living substitutes for coronary and peripheral artery bypass graft surgery. However, one of the main limitations in tissue engineering is vascularization of the construct before implantation. Such a vascularization could play an important role in graft perfusion and host integration of tissue-engineered vascular adventitia.
