[Periprosthetic infection after total hip replacement : Risk factors for an early infection after primary implantation].

Background: Periprosthetic infection is one of the most serious complications in primary arthroplasty. The infection rates reported in the current literature range from 0.36 to 2.

In vitro detection of Candida and Aspergillus antigen in parenteral nutrition and fixed combinations of piperacillin-tazobactam.

Background: Screening for Aspergillus (Asp-AG) and Candida antigen (Ca-AG) with immunoassays is established for stem cell recipients at high risk for invasive fungal infections (IFI). While parenteral nutrition (PN) will be applied in case of complications leading to insufficient alimentation, piperacillin-tazobactam (TZP) is started at the onset of febrile neutropenia.

Objectives: The aim of this study was to investigate drug-laboratory interactions between PN and TZP and both immunoassays which could affect the specificity of the assays and lead to the false assumption of an IFI.
