[Periorbital, blue tumour in newborn twins]. / Periorbitale, blauwe zwelling bij pasgeboren tweeling.

Newborn twins both had a blue, smooth tumour in the inner angle of the orbit; one of them had two such tumours. They were diagnosed with congenital dacryocystoceles. If decompression into the nose is not effective, patients should undergo probing early in life to reduce the incidence of dacryocystitis and orbital cellulitis.

Colonization dynamics of antibiotic-resistant coagulase-negative Staphylococci in neonates.

Coagulase-negative staphylococci (CoNS) isolated in neonatal late-onset sepsis are often antibiotic resistant. We analyzed CoNS from skin and feces of neonates during hospitalization. Antibiotic resistance of skin isolates increased during hospitalization, especially in Staphylococcus haemolyticus. Staphylococcus warneri showed low antibiotic resistance. Our data suggest that different CoNS species may play distinct roles in colonization.
