[Predictive value of red blood cell distribution width for acute kidney injury in children with sepsis].

Objective: To study the clinical value of red blood cell distribution width (RDW) in the early prediction of acute kidney injury (AKI) in children with sepsis.

Methods: A total of 126 children with sepsis were divided into an AKI group (n=66) and a non-AKI group (n=60) according to the presence or absence of AKI. These patients were also classified into high-RDW and low-RDW groups according to the mean RDW.

[Role of procalcitonin in the diagnosis of acute pyelonephritis in children].

Objective: To study the role of procalcitonin (PCT) in the diagnosis of acute pyelonephritis (APN) in children.

Methods: Retrospective analysis was performed on the clinical records of children aged under 3 years who were diagnosed with primary urinary tract infection (UTI) from September 2011 to February 2012. These children were divided into those with upper UTI (UUTI) (APN) and those with lower UTI (LUTI) (non-APN) based on 99mTc-dimercaptosuccinic acid (DMSA) renal scan results as a gold standard.
