We assessed the in vivo efficacy of surgical and N95 (respirator) masks to filter reverse transcription-polymerase chain reaction (RT-PCR)-detectable virus when worn correctly by patients with laboratory-confirmed acute influenza. Of 26 a clinical diagnosis influenza, 19 had confirmed RT-PCR, 9 went on complete study. Surgical were equally effective preventing spread PCR-detectable

Few data exist concerning possible infectious complications associated with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA). The present prospective evaluation was undertaken in order to determine the incidence of bacteraemia and EBUS-TBNA. Consecutive patients undergoing EBUS-TBNA for mediastinal or hilar lymph node lesions were studied. Venesection performed within 60 s TBNA aerobic anaerobic blood culture. Sterile saline washing needles also performed....

Mannose-binding lectin (MBL) is an important mediator of innate immunity and synthesized primarily by the liver. Low MBL levels are common, due to polymorphisms in gene encoding (MBL2), associated with increased risk infection, particularly when compromised. We report a large, retrospective study that examined association between status clinically significant infection following orthotopic liver transplantation.One hundred two donor-recipient transplantation pairs were studied. Five promoter...
