Article Synopsis
  • The study focused on children under 24 months with minor head trauma who had repeated imaging to assess the need for follow-up after an initial CT scan, following PECARN guidelines.
  • Out of 741 enrolled children, 36 had additional intracranial injuries noted on MRI, even after being classified as having isolated skull fractures (SF) in their initial CT scans.
  • Findings showed that certain factors, like subcutaneous hematoma and the nature of skull fractures, were linked to new intracranial injuries, suggesting that some kids with SF may not need surgery if there's no active intracranial injury on the first CT scan.

Article Synopsis
  • A multicenter retrospective study analyzed 343 children who had renal ultrasounds during their first febrile urinary tract infection (fUTI) from 2013 to 2020, focusing on the effects of sonographic temporary nephromegaly.
  • The study found that children with temporary nephromegaly experienced longer fevers and antibiotic treatments, and had higher levels of inflammatory markers and recurrence rates of fUTI compared to those without nephromegaly.
  • Additionally, a logistic regression indicated that children with temporary nephromegaly had an increased likelihood of vesicoureteral reflux (VUR), suggesting that nephromegaly may be an early indicator of potential fUTI recurrence and VUR in affected kids

Aim: In 2022, the Japanese Orthopaedic Association developed "Locomo Age," which can be used to measure mobility. The potential effects of measuring Locomo Age on motivation to exercise are yet to be explored. This study aimed to determine whether the measurement of Locomo Age improved motivation for exercise.

To increase the prediction accuracy of positive oral food challenge (OFC) outcomes during stepwise slow oral immunotherapy (SS-OIT) in children with a hen's egg (HE) allergy, we evaluated the predictive value of the combination of antigen-specific IgE (sIgE) with antigen binding avidity and sIgG4 values. Sixty-three children with HE allergy undergoing SS-OIT were subjected to repeated OFCs with HE. We measured the ovomucoid (OVM)-sIgE by ImmunoCAP or densely carboxylated protein (DCP) microarray, sIgG4 by DCP microarray, and the binding avidity of OVM-sIgE defined as the level of 1/IC (nM) measured by competitive binding inhibition assays.

Purpose: Although morphological renal abnormalities in children with febrile urinary tract infection (fUTI) have been showed a predictive factor for recurrent infection, there are no available data on recurrence regarding sonographic renal enlargement at first fUTI episode, especially focusing on whether renal enlargement is temporary or not.

Materials And Methods: This cohort study reviewed the medical records of children who underwent renal ultrasound during their first fUTI during 2005-2013 and who were aged <15 years at diagnosis. We defined a kidney as temporary enlarged when the kidney length was ≥2 standard deviation above normal renal length for that age on sonography or a difference of ≥1 cm in sonographic length between the right and left kidneys, following normal renal length after antibiotic treatment.
