A mean steady state target concentration greater than 10 mg/l at trough can be achieved by an oral dose of 25 mg x kg(-1) x d(-1) in premature neonates at 30 weeks' postconception, 45 mg x kg(-1) x d(-1) at 34 weeks' gestation, 60 mg x kg(-1) x d(-1) at term, and 90 mg x kg(-1) x d(-1) at 6 months of age. The relative rectal bioavailability is formulation dependent and decreases with age. Similar concentrations can be achieved with maintenance rectal doses of 25 (capsule suppository) or 30 (triglyceride suppository) mg. kg-1. d-1 in premature neonates at 30 weeks' gestation, increasing to 90 (capsule suppository) or 120 (triglyceride suppository) mg x kg(-1) x d(-1) at 6 months. These regimens may cause hepatotoxicity in some individuals if used for longer than 2-3 days.

Our study suggests that acupuncture therapy may be effective in diminishing both pain and emergence agitation in children after BMT insertion without adverse effects.

Balloon dilatation is a safe and effective therapy for esophageal strictures in children with recessive dystrophic epidermolysis bullosa. Limited upper endoscopy and endotracheal intubation are well tolerated by these children. This approach should be considered as primary therapy in this clinical setting.
