Twelve diabetic children--eight in ketoacidosis, three with insulin refractory hyperglycemia, and one postoperative patient--were treated with continuous, low-dose, intravenous infusion of insulin. The eight ketoacidotic children with a mean serum glucose concentration on admission of 631 mg/dl and bicarbonate value of 6.8 mM/1 were given regular insulin, 0.1 U/kg, slowly by bolus injection followed by a sustaining infusion of 0.1 U/kg/hour. Plasma glucose concentration fell at a mean rate of 82 mg/dl/hour. Euglycemia with concomitant improvement in the metabolic disorder was achieved with a mean dose of insulin, 0.68 U/kg, given over four to 10 hours. Mean plasma insulin in those children who had not previously received insulin was 55 muU/ml, well within the normal physiologic range. Growth hormone and serum triglyceride levels, low initially, rose with insulin therapy before returning to control values. Continuous low-dose insulin infusion is simple, safe, and effective, avoids confusion and empiricism, and appears to be the method of choice for the treatment of diabetic ketoacidosis or insulin resistance.

The pituitary-thyroid axis, serum prolactin and growth hormone levels were studied in 29 patients within 9 d of onset of acute ischaemic stroke. When compared to a control group of 80-year-old volunteers (n = 33), stroke patients were found to have elevated free thyroxine indices (P = 0.008), after adjustment for age and sex. Seventeen (81%) of the stroke patients showed a paradoxical rise in growth hormone in response to thyrotropin releasing hormone (TRH). In a multiple regression model, disorientation was associated with a low thyrotropin response to TRH (P = 0.02 and P = 0.04; 20 and 60 min after TRH, respectively). Disorientation was also positively correlated with the prolactin response to TRH (P = 0.045 after 60 min). Growth hormone levels were predicted by extensive motor impairment (P = 0.02). In conclusion, changes in pituitary and thyroid hormones were commonly observed after stroke and were closely associated with cognitive and/or motor impairment.

Growth hormone (hGH) is a measurand belonging to ISO category 4, indicating intrinsic unavailability of a reference measurement procedure and primary standard material. Large between-method differences have been raising confusion, especially in the interpretation of results of stimulation tests for exclusion of juvenile growth hormone deficiency. Within the framework of the external quality assessment scheme (EQAS) of the SKML (Dutch Foundation for Quality Assessment in Clinical Laboratories), attempts to reduce between-method variation of hGH measurements have been made, starting in 1994 with an inter-laboratory comparison of 9 different immunoassays by using a panel of sera and standard materials available at that time. Methods appeared to differ from each other largely in a systematic, sample-independent manner. These systematic differences are reflected in the hGH measurement results obtained in commutable sera. A commutable serum pool was introduced as a consensus reference material, permitting correction of each method's results to a common scale. Pair wise comparisons ("twin studies") were carried out to investigate and corroborate the effectiveness of this material for harmonization. A significant reduction of the between-laboratory coefficient (CV) of variation from 22 to 9.0% was attained.
