Effect of age and sex on human drug metabolism.

The capacity of inpatients in a geriatric hospital to metabolize drugs was measured. The mean plasma half-life values with antipyrine and with phenylbutazone were found to be 45% and 29% greater respectively in patients than in young controls. When women alone were considered the half-life of antipyrine was 78% longer in the elderly group. In a number of elderly individuals the rate of metabolism of these two drugs was found to be extremely slow. This decreased ability to metabolize drugs may contribute to the known high incidence of adverse drug reactions in the elderly.Within the control group a significant sex difference in the rate of antipyrine metabolism was found, the mean half-life being 30% longer in the males. It is clear from these results that the age and sex of subjects must be taken into account in studies of human drug metabolism.

Surgical treatment of thyrotoxicosis.

A retrospective study of thyrotoxic patients treated by subtotal thyroidectomy between 2 and 21 years ago in the north-east of Scotland showed that 20% of the patients could not be identified or traced at the time of the survey. The thyroid status of 40% of patients followed up was abnormal.It is now accepted that radioiodine treatment of thyrotoxicosis is followed by a significant incidence of late onset hypothyroidism, and life-long follow-up is regarded as obligatory. The findings in this study indicate that similar methods of aftercare are required for surgically treated patients and for all patients receiving thyroxine-replacement therapy.

Computer-assisted follow-up register for the north-east of Scotland.

An automated follow-up register for the detection of iatrogenic thyroid disease has been established as a joint venture between the general practitioners in the north-east of Scotland and the thyroid clinic of Aberdeen General Hospitals.The data-processing operations in the system are handled by an International Computers Limited 4/50 computer. Patients are followed up at predetermined intervals and the system has been designed to process, screen, and store clinical and biochemical follow-up data and report results to the patients, general practitioners, and the hospital records department.
