Orbital hemangioma requiring enucleation in a premature infant.

A preterm male infant developed a rapidly growing, treatment-resistant orbital hemangioma. Despite aggressive management, the patient required enucleation of his right eye and image-guided ethanol sclerosis to limit tumor progression intracranially.

Reticulated platelet percentages in term and preterm neonates.

Objectives: The authors aimed to determine whether their reticulated platelet percentage (RP%) analysis technique was suitable for use in term and preterm neonates and to characterize RP% values among nonthrombocytopenic neonates.

Methods: The authors modified a whole blood method that uses dual-color CD41 staining for platelet gating and thiazole orange for RNA content, combined with RNase treatment of half the sample to subtract non-RNA fluorescence. The RP% was measured in samples from 10 healthy adults and then a longitudinal study was performed in 15 nonthrombocytopenic preterm neonates on days of life 0 to 1, 2 to 5, 6 to 10, and then weekly until day 28.
