    Notes: Summary Twenty-four hour profiles of plasma C-peptide an index of endogenous insulin secretion, were performed in 15 Type 1 (insulin-dependent) diabetic children. Plasma C-peptide was detectable in six children, of whom four (‘C-peptide producers’) had peak values above normal fasting levels. In each of the six children with residual B cell function, there was a close correlation between plasma C-peptide and simultaneous blood glucose (r〉 0.50, p〈 0.05). Post-breakfast peak blood glucose was 10.2 ± 1.7 mmol/l (mean ±SEM) in the ‘C-peptide producers’ and 18.7 ± 1.7 mmol/l in the 11 children with low or no detectable C-peptide. Mean M-value, an index of deviation from an ideal blood glucose, was lower in the ‘C-peptide producers’ (p〈0.05). It is concluded that residual functioning B cells in diabetic children behave physiologically in that insulin secretion fluctuates in accordance with the prevailing blood glucose; and that the pattern of action of injected insulin is more critical in non-C-peptide producers who lack the post-prandial dampening effect provided by residual endogenous insulin secretion.

    Notes: Abstract A 5-year-old boy is described who presented with episodes of hypoglycaemia triggered by mild infections or fever. Subnormal glucocorticoid production was confirmed by demonstrating low urinary excretion of free cortisol, low plasma cortisol concentrations that did not rise after glucagon and ACTH stimulation, and by elevated plasma ACTH levels. The selective nature of the abnormality was confirmed by demonstrating normal plasma electrolyte concentrations and blood pressure on a salt-restricted diet. Plasma renin activity and plasma aldosterone levels were also normal and responded appropriately to salt restriction and to frusemide-induced diuresis. Starvation-induced hypoglycaemia was associated with raised levels of blood ketone bodies and low blood alanine concentrations. Catecholamine secretion during hypoglycaemia was reduced. Glucocorticoid replacement therapy was effective in restoring normal glucose homeostasis.

    Notes: Abstract Soon after birth a 36-weekgestational age, appropriate for dates, newborn infant developed hyperinsulinaemic hypoglycaemia which responded to diazoxide and glucose infusion. While normoglycaemic, he became increasingly ill with high lactate, pyruvate, and alanine levels. Provocation tests suggested a defect in lactate handling. Dichloroacetate (DCA) was given and resulted in the prompt normalisation of his metabolic profile with no recurrence after discontinuation of the drug. A second episode of hyperinsulinaemic hypoglycaemia followed and this was controlled satisfactorily by short term diazoxide treatment. Diazoxide treatment could be stopped at the age of 1 month. Although at the age of 1.5 years the infant is retarded developmentally, there has been no recurrence of lactic acidosis nor hyperinsulinaemic hypoglycaemia. The association of lactic acidosis and hyperinsulinism, and the use of DCA in this circumstance have not been reported previously.

    Notes: Abstract There are many challenges facing electronic commerce in the real world. The technical ability to trade electronically may seem to be enough of a challenge on its own to warrant success. However, other issues, like the confidence of users that the technology meets their needs, must also be addressed. This confidence will stem from a number factors like the interoperability of different implementations, the confidence in the companies providing the infrastructure, and the legal recognition of the resulting agreements to trade. These issues are being addressed in external organisations that are aimed at agreeing technical standards, regulations, and business codes of practice. This paper looks at the activities of such organisations and what impact they will have on BT' work.
