  • Calcium stimulation test for hyperinsulinism in infancy
    L J Abernethy

    We read with great interest the consensus article on the investigation and management of hyperinsulinism in infancy (1). The authors discuss the value of the intra-arterial calcium stimulation test, but speculate that there is a significant risk of bowel infarction.

    Intra-arterial calcium stimulation for localisation of insulinomas in adult patients has been described by several authors (2,3,4). To our knowledge...

  • Severe retinopathy of prematurity survival rates
    Arun K Manglik

    Wonderful work by Vyas et al on ROP and its incidence in different cities of Britain. The statistically significant difference in the incidence of ROP in different centres may be related to the differences in the level of care provided. The advancements in neonatal care, particularly the use of surfactant and the resultant reduction in the requirements of O2 has greatly influenced outcome and possible development of ROP (...

  • A simple practice to increase red cell transport in newborns
    Cory Mermer

    The finding of Pladys et al (1), that preterm infants are able to compensate for deficiencies in hematocrit by increasing cardiac output is reassuring. However, it would seem to be a good idea to attempt to minimize the need for such efforts, which are another added stress to an already overburdened newborn’s system.

    There is a simple procedure with little, if any risk that can increase red cell transport or...
