An improved olive oil overall migration test for plastics using Karl Fischer titration.

Karl Fischer titration has been used to eliminate the need to humidity-condition food contact plastics under test for overall migration into olive oil. The water content of the oil is measured before and after the migration test. This direct measure of the loss (or uptake) of water by the test plastic is then used in calculations of the overall migration. The use of Karl Fischer titration gives faster analysis with reduced labour input. The time savings varied from a few days to several weeks depending on the type of plastic. Karl Fischer titration is particularly useful in the high temperature testing of polar plastics where incomplete humidity conditioning can lead to erroneous results. The technique should be equally valuable when employing sunflower oil or the triglyceride HB307 in place of olive oil.

Korsakoff's psychosis in Scotland: evidence for increased prevalence and regional variation.

Surveys of new long-stay mental hospital patients in Scotland find that 9% have a diagnosis of alcohol-related brain damage, mainly Korsakoff's psychosis (KP), whereas the rate was 5% in the old long-stay patients. The national hospital database shows a rise in rates of KP in figures for discharge diagnosis and for diagnosis of hospital residents during the past three decades. There is an argument for more specialized provision given the significance of this group of patients.
