Breast feeding and the development of type 1 diabetes mellitus.

A case-control study was conducted to study the proposed inverse relationship between breast feeding and incidence of Type 1 diabetes mellitus. All Danish diabetic men born in Copenhagen during 1959-1964 and/or residing there for the first year of life (n = 119) were identified and a search made for their post-natal health visitor records. These include data on birth weight, birth length, immunizations, and feeding habits. A total of 77 cases were re-identified. No differences were found with respect to clinical characteristics between these cases and those not identified. For each diabetic subject, two control children with date of birth identical to the diabetic cases were drawn from health visitor records. Cases and controls did not differ with respect to maternal age, or birth weight or length. Overall, the statistical analysis failed to confirm the hypothesis of an association between duration of breast feeding and subsequent diabetes risk.

The ExacTech blood glucose testing system.

The ExacTech system, a new device for home measurement of blood glucose was tested in the laboratory, in the out-patient clinic, and by diabetic patients. The system is based on an electrochemical principle, and consists of specially impregnated strips and a small, pencil-shaped meter. (1) Six meters were tested in the laboratory at blood glucose concentrations of 4, 10 and 20 mmol/l. Low coefficients of variation were found at 10 and 20 mmol/l, but those at 4 mmol/l were rather high (approximately 10%). Analysis of variances showed no difference in the between and the within variation of the meters. (2) The blood glucose concentrations of 50 consecutive out-patients were determined by the ExacTech system and a standard laboratory method. Correlation analysis showed an r value of 0.95 (P less than 0.001). (3) The results obtained by 13 patients repeating the correlation experiment were in agreement with the second part of the study. The ExacTech system is very simple to operate by the patients, and can be recommended for home monitoring of blood glucose.
