It is estimated that people in industrialised countries have a 1% chance of suffering from a leg ulcer at some time in their life. The majority of leg ulcers are associated with circulation problems; poor blood return in the veins causes venous ulcers (around 70% of ulcers) and poor blood supply to the legs causes arterial ulcers (around 25% of ulcers). Treatment of arterial leg ulcers is directed towards correcting the poor arterial blood supply, for example, by surgically correcting arterial blockages, and by supporting ulcer healing using topical agents (medicines in cream/ointment) and wound dressings. There are a large number of topical agents and wound dressings available and it is unclear what impact these have on ulcer healing. ⋯ There is insufficient evidence to determine whether the choice of topical agent or dressing affects the healing of arterial leg ulcers. Inadequate description of the people in the one included trial means that the results cannot be easily applied to other clinical populations.

ReviewEarly intravenous nutrition for the prevention of neonatal jaundice.
The early institution of enteral feeding in the first few days of life is known to impact on the development of unconjugated hyperbilirubinaemia. However, the effect of early intravenous nutrition on neonatal jaundice remains unknown. ⋯ Decisions regarding the institution of early intravenous nutrition must continue to be based upon factors others than its effect on neonatal jaundice.
