Does pIVKA-II correlate with INR but not protein C or protein S concentrations in cord blood among newborns?
PIVKA-II seems to be a sensitive indicator of mild VK deficiency. Further studies are needed to investigate the lack of relationship between PIVKA-II and functional protein C or S levels.
The safety and accuracy of SLNB in the neck and parotid nodal basins were similar to those in non-head and neck sites. However, the technique is technically demanding in this region. In this small series SLNB did not alter disease outcome.
