Normoblastemia multinuclear en un recién nacido secundaria a hipoxia / Multinucleated normoblastemia in a newborn secondary to hypoxia

Es posible detectar normoblastos en los frotis de sangre periférica de los recién nacidos. En general, la cantidad de normoblastos por cada 100 leucocitos está en el intervalo de 0 a 10. Se observan con más frecuencia de lo usual ante una situación de hipoxia porque la hipoxia intrauterina aumenta la producción de eritrocitos. Sin embargo, no se había informado antes un caso de normoblastos multinucleados en un recién nacido a causa de la hipoxia. Presentamos el caso de un recién nacido con normoblastos multinucleados secundarios a hipoxia intrauterina. Este caso es importante porque es la primera vez que se han detectado normoblastos multinucleados en el frotis de sangre periférica de un recién nacido hipóxico.

Normoblasts may be seen in peripheral blood smear of newborns. The number of normoblasts per 100 white blood cells is generally in the range of 0-10.They can be seen more common than usual in hypoxic condition, because intrauterine hypoxia increases the production of red blood cells. However, multinucleated normoblasts in a newborn caused by hypoxia haven't been reported before. We present a newborn with multinucleated normoblasts secondary to intrauterine hypoxia. This case is important; because it is the first time multinucleated normoblasts in peripheral blood smear of a hypoxic newborn has been detected.

Vascular endothelial growth factor levels in newborns with meconium stained amniotic fluid.

OBJECTIVE: The effects of meconium-stained amniotic fluid (MSAF) on cord blood vascular endothelial growth factor (VEGF) levels have not been explored. The aim of this study was to verify whether MSAF influences cord blood VEGF levels in healthy term neonates and we can use cord blood VEGF levels in infants with MSAF as an indicator of fetal distress. METHODS: Using an enzyme-linked immunosorbent assay double sandwich method, plasma VEGF levels were determined in 18 healthy term neonates with MSAF and in 16 healthy term neonates without MSAF. RESULTS: VEGF plasma levels were not significantly different between healthy term neonates with or without MSAF. CONCLUSION: Intrauterine meconium passage could not affect VEGF levels on cord blood in term newborn infants and VEGF level may not be used as an indicator of fetal distress in infants with MSAF.
