Modified Serum ALP Values and Timing of Apparition of Knee Epiphyseal Ossification Centers in Preterm Infants with Cholestasis and Risk of Concomitant Metabolic Bone Disease of Prematurity.

The usefulness of serum alkaline phosphatase (ALP) and phosphorous in screening and monitoring of metabolic bone disease of prematurity (MBDP) still has some limitations, especially in preterm infants with concomitant conditions such as cholestasis. We aimed to assess a modification of serum ALP (M-ALP) as a biomarker for MBDP in preterm infants, and the use of ultrasound monitoring for the apparition of knee ossification centers as marker of bone mineralization. Biochemical and clinical registers were taken from 94 preterm newborns <32 weeks.

Antimicrobial susceptibility of microorganisms that cause urinary tract infections in pediatric patients.

Introduction: Cumulative susceptibility reports are a valuable tool for the empirical treatment of urinary tract infections, especially in the current context of increasing resistance rates. Our objective was to analyze the antimicrobial susceptibility of bacterial isolates in urine cultures of pediatric patients during a five-year period.

Methods: Retrospective study of urine cultures from 2011 to 2015.

Benign acute myositis associated with H1N1 influenza A virus infection.

We report the clinical and laboratory features of four children with benign acute myositis observed during the current outbreak of the novel H1N1 influenza A virus. Our findings were similar to those of previous reports for benign acute myositis associated with seasonal influenza. No patients needed oseltamivir, and all of them showed quick recovery without recurrences.
