Procalcitonin at 12-36 hours of fever for prediction of invasive bacterial infections in hospitalized febrile neonates.

Aim: We aimed to investigate the performance of procalcitonin (PCT) assay between 12 and 36 h after onset of fever (PCT H12-H36) to predict invasive bacterial infection (IBI) (ie, meningitis and/or bacteremia) in febrile neonates.

Methods: We retrospectively included all febrile neonates hospitalized in the general pediatric department in a teaching hospital from January 2013 to December 2019. PCT assay ≤ 0.

Cefepime population pharmacokinetics and dosing regimen optimization in critically ill children with different renal function.

Objective: Cefepime is commonly used in pediatric intensive care units, where unpredictable variations in the patients' pharmacokinetic (PK) variables may require drug dose adjustments. The objectives of the present study were to build a population PK model for cefepime in critically ill children and to optimize individual initial dosing regimens.

Methods: Children (aged from 1 month to 18 years; body weight >3 kg) receiving cefepime were included.

Are β-lactam concentrations adequate in severe sepsis and septic shock in children?

Aim Of The Study: Early administration of appropriate antibiotic therapy with adequate concentration is the cornerstone of the severe sepsis and septic shock's treatment. We aim to describe the plasma concentration of the most used β-lactams in critically ill children, to describe the rate of patients with suboptimal exposure, and associated clinical and biological factors.

Methods: From January 2016 to May 2017, children less than 18 years old with severe sepsis or septic shock were included.

Recurrent Acute Septic Arthritis Caused by Kingella kingae in a 16-Month-Old Boy.

We describe the first case of 2 consecutive acute septic arthritis infections of both knees caused by the same virulent strain of Kingella kingae belonging to the virulent sequence type complex 14, in a 16-month-old boy. Both infections occurred after viral upper respiratory tract infections.
