Good glycaemic control is important in preventing the acute and long-term complications of diabetes mellitus. We assessed long-term glycaemic control using glycosylated haemoglobins in 83 diabetic patients, of mean age 47 years and of mean known duration 4.5 years, attending Port Moresby General Hospital over a one-year period. Significant improvement in glycaemic control was observed in only 11 (13%) of the patients. Glycaemic control worsened in 13 (16%) and no change was observed in the remainder (71%). Mean glycosylated haemoglobin and fasting plasma glucose levels were similar at the beginning and end of the study period. Over a one-year period 53 patients (64%) exhibited poor control with mean glycosylated haemoglobin levels exceeding 10%. Among the 19 newly diagnosed diabetic patients (23% of the total) glycaemic control improved in only 2 (11%). Glycaemic control was not influenced by sex, treatment, obesity or duration of diabetes. The demonstration of poor metabolic control in the majority of patients suggests that urgent measures are needed to reevaluate the management of diabetic patients, particularly with respect to education and diet. This may improve the poor survival rates reported in diabetic patients from Papua New Guinea.

Medicine has, in recent years, incorporated wave after wave of new scientific discoveries and technologies. Molecular medicine is one of these technologies and shows a dramatic example of the impact of advances in basic science. Advances in molecular biology have revolutionized daily clinical practice, particularly in developed countries, such that practitioners who received their medical education decades ago now need to adapt to this new discipline. While molecular medicine may not be a priority health issue in developing countries such as Papua New Guinea, it is equally important to ensure that the basic principles of knowledge and understanding of what goes on in that field form part of today's teaching of all practitioners of medicine and allied health workers. The three papers in this series aim to present molecular biology and its medical applications in as simple and lucid a manner as possible so that its scientific basis and principles as well as its potential for diagnosis and management of diseases are well appreciated.

Mean values and reference ranges are presented for serum creatinine and serum urea in Melanesian men and women aged over 50 years from coastal Papua. The values are presented separately for three age groups, 51-60, 61-70 and 71-85 years, but there was no significant difference between them. The values for women were lower than for men in all age groups.
