Fracture strength of 3-units fixed partial dentures fabricated with metal-ceramic, graphene doped PMMA and PMMA before and after ageing: An in-vitro study.

Objectives: To evaluate the fracture strength and linear elongation at break of three-units fixed partial dentures (FPDs) fabricated with traditional and new materials for fixed prosthodontics before and after ageing.

Methods: Sixty models of three-units FPDs were fabricated and cemented onto a Co-Cr model simulating the replacement of a maxillary second premolar. The samples were randomly divided into 3 groups: metal-ceramic (MCR), graphene-doped polymethylmethacrylate (PMMA-GR) and polymethylmethacrylate (PMMA).

[Hyperbaric oxygen therapy as an adjunctive treatment for acute mediastinitis due to oesophageal perforation: a case report].

In spite of antibiotic treatment, of progress of resuscitation and surgery, acute posterior mediastinitis remains associated to a high mortality. We report a case of man with posterior mediastinitis by performing of the cervical oesophagus. While his state remained still with the classic treatment, the contribution of the hyperbaric oxygen therapy quickly improved his state.

[Clinical evaluation of acetate-free biofiltration at 84 0/00 in patients with chronic renal insufficiency].

We report in this study the outcome of chronically hemodialysed patients with a new technique: Acetate free biofiltration 84@1000. This study is divided into two steps: during the first period we studied the hemodynamic stability of the technique in patients hemodynamically unstable under bicarbonate hemodialysis. During the second period we compared the hemodynamic effects and the quality of dialysis in these patients with other patients under bicarbonate hemodialysis.
