In a multicentre clinical trial 54 children aged 4.0 to 17.3 years, who had growth hormone deficiency that had not previously been treated, were given biosynthetic methionyl growth hormone (somatrem) 4 units three times a week by subcutaneous or intramuscular injection for one year. Height was measured every three months for at least one year before and during treatment. Forty two patients responded to treatment with an increase in growth of greater than 1.5 cm/year. The remaining 12 who grew more slowly were less obviously short and had a higher pretreatment growth than those who responded. The three who responded and the one who did not had undergone therapeutic spinal irradiation before starting the drug. If a whole year's pretreatment growth rate of less than 5 cm/year had been used as a diagnostic criterion the prediction of those who responded would have slightly improved. About two thirds of the patients developed antibodies against growth hormone and Escherichia coli protein; these were, however, of low and fluctuating titre and binding capacity, and did not influence the response to treatment. No adverse side effects were encountered. We conclude that somatrem is a safe and effective alternative to pituitary growth hormone. [ABSTRACT FROM AUTHOR]

Morning hyperglycaemia remains a challenge to conventional insulin regimens. Eighteen adolescents participated in a one year crossover study to examine the effect of delaying the evening intermediate acting insulin from before the evening meal to bedtime. This three injection regimen caused slightly higher blood glucose concentrations in the early part of the night, and lower concentrations in the morning, but no overall change in glycosylated haemoglobin concentrations (HbA1c). Seasonal change accounted for substantially more of the variance in HbA1c concentrations than did the regimen change. The three injection regimen did not alter the frequency of hypoglycaemic episodes. Metabolic control on both regimens might have been improved by more intensive monitoring and medical attention. This study suggests that factors beyond medical control, such as seasonal variation, may contribute more to the control of diabetes in adolescents than changes in conventional insulin regimens, particularly when unaccompanied by intensive monitoring.

Sixteen children (aged 3 to 12 years) participated in a 12 month crossover study comparing bedtime with teatime insulin injections in an endeavour to reduce morning hyperglycaemia. Blood glucose values were lower at lunch and at teatime on the later injection, but higher at bedtime and midnight. There was no overall change in glycosylated haemoglobin. Despite more frequent mild hypoglycaemic attacks, parents preferred the convenience of the later injection. Analysis of individual children's glycosylated haemoglobin values showed that those whose metabolic control improved on the later injection were younger and went to bed earlier, indicating that this regimen may have a place in the management of younger children with diabetes mellitus.

Total glycosylated haemoglobin (HbA1) levels from capillary blood were studied retrospectively during a 1-year period in 148 diabetic children aged between 1.9 and 16.8 years. The clinic range for HbA1 was 6.7 to 22.2% and the results were normally distributed (mean +/- SD 13.2 +/- 2.8%). The normal range in non-diabetics using this method is 4.9 to 8.0%. Results from children who had had diabetes for more than 5 years were higher than those from children with diabetes of 2 to 5 years' duration. Girls had higher average values during the 1-year period than boys. HbA1 measurement serves to identify the deficiencies of current diabetic treatment regimens. It also has more immediate practical benefits in focusing attention on children whose control is deteriorating. [ABSTRACT FROM AUTHOR]

Two infants with spontaneous perforation of the common bile duct are described. One presented with mild jaundice, dark urine, acholic stools, and hydroceles, the other with bilateral inguinal hernia. In both the diagnosis was unsuspected until bile-stained ascites was discovered. Both eventually developed bile-staining of the scrotum. Neither was acutely ill. The 131I-Rose Bengal faecal excretion test showed reduced faecal excretion at 8% and 12% of the injected dose with 16-5 and 17%/dl of the dose being recovered in the ascitic fluid 48 hours after intravenous injection. The ascitic:plasma ratio of isotope at that time was 32:1 and 28:1. Operative cholangiography in both showed a perforation at the junction of the cystic duct and common bile duct with no contrast entering the duodenum. Cholecystenterostomy using a Roux-en-Y loop of jejunum produced a rapid sustained recovery and is suggested as the treatment of choice. This condition should be considered in the differential diagnosis of obstructive jaundice in infancy since early surgical correction is necessary. [ABSTRACT FROM AUTHOR]
