Linked Th17 and Calgranulin Responses in Maternal-cord Blood Dyads of Preterm Gestations with Histologic Chorioamnionitis.

Introduction: Maternal-fetal immune crosstalk mechanisms are increasingly identified in the pathogenesis of gestational disorders, including histologic chorioamnionitis (HCA). Although an inflammatory Th17 immune phenotype has been described in preterm neonates with HCA, the associated maternal Th17 response is relatively unknown. To refine our understanding of Th17 biology in this context, we examined Th17 responses in maternal-cord blood dyads of preterm gestations.

Elevated neutrophil-lymphocyte ratios in extremely preterm neonates with histologic chorioamnionitis.

Objective: Histologic chorioamnionitis (HCA) is a placental inflammation linked to preterm birth and adverse neonatal outcome. The neutrophil-lymphocyte ratio (NLR) can identify various inflammatory disorders, however its utility in HCA is not clear. Our goal was to examine NLR values and HCA diagnoses in at-risk pregnancies and neonates.

Growing Up Fast: Managing Autism Spectrum Disorder and Precocious Puberty.

Case: John is a 4-year-old boy with autism spectrum disorder (ASD) and developmental delay who presented with concerns about increasing aggressive behavior at a follow-up visit with his developmental-behavioral pediatrician. Diagnosis of ASD was made via Diagnostic and Statistical Manual of Mental Disorders, 5th version criteria at initial evaluation at 34 months. Medical history at that time was pertinent for rapid linear growth since the age of 1 and recent pubic hair growth and penile enlargement.
