Surgical site infections in primary total hip and knee replacement surgeries, hemiarthroplasties, and osteosyntheses at a Brazilian university hospital.

We report a case-control study involving 663 primary orthopedic surgeries with a 12.7% rate of surgical site infections (SSIs). The respective frequencies of superficial incisional, deep incisional, and organ/space infections were 22.

Two outbreaks of mixed etiology associated with central venous catheters inserted by phlebotomy in critical neonates.

Staphylococcus aureus and coagulase-negative staphylococci are the main cause of sepsis in Neonatal Intensive Care Unit (NICU). Central venous catheters (CVCs) are an important part of critical neonates' treatment and are associated with sepsis. The aim of this study was to investigate two outbreaks caused by Staphylococcus aureus and Staphylococcus epidermidis associated with CVC inserted by phlebotomy in critical neonates.
