We have shown previously that blood sampling via umbilical artery catheters decreases cerebral oxygenation and cerebral blood volume in preterm infants. To evaluate alternative methods, we assessed the effects of blood sampling via umbilical vein catheters in a cohort of preterm infants. ⋯ Umbilical vein blood sampling reduces cerebral oxygenation and cerebral blood volume. The magnitude of the effects is similar to those during umbilical artery blood sampling.

To evaluate levels of C-reactive protein (CRP) during febrile episodes in children with periodic fever, aphthous stomatitis, pharyngitis and cervical adenitis syndrome (PFAPA). ⋯ Levels of CRP are substantially increased during febrile episodes in children with PFAPA. High levels of CRP may suggest a role for immunological mechanisms in PFAPA, and may raise the suspicion of PFAPA when measured in children with periodic fever of unknown origin.
