The amphetamine derivatives p-chloroamphetamine (pCA), 3,4-methylenedioxymethamphetamine (MDMA, 'Ecstasy') and D-fenfluramine can, if given repeatedly in high doses to rats, produce a degeneration of serotonergic nerve terminals which we have previously shown to result in a reduction in D-fenfluramine-evoked release of 5-HT in vivo. It is therefore(More)
Two case reports are presented of significant psychiatric disorders associated with ingestion of 'Ecstasy' (3,4-methylenedioxymethamphetamine), a recreational drug whose use appears to be increasing. In one case, the patient developed a brief paranoid psychosis which recurred and persisted for at least a month after he took a second dose of the drug. In the(More)
This short article reviews HPLC-EC methodology that we are currently applying to measure DA, 5-HT and their acid metabolites in rat brain dialysates collected in vivo. HPLC-EC systems based on standard-bore HPLC columns are described which are sufficiently sensitive to allow detection of the monoamine transmitters and their metabolites in regional brain(More)
BACKGROUND Evidence from open label studies has indicated that patients with dementia with Lewy bodies (DLB) and Parkinson's disease dementia (PDD) do better than those with other diagnoses, including Alzheimer's disease (AD). In addition, those with dementia of moderate severity do better than those with mild severity. METHOD Data collected for the(More)
A multiple skin test survey of school children (aged 5-15 years) living in Agra, India showed very high levels of sensitisation to numerous species of mycobacteria and little difference in tuberculin positivity between those with and without BCG scars. A total of 136 children aged 3 months to 8 years, living in Agra, were skin tested with Tuberculin and(More)
article Over the past 100 years, our understanding of dementia has undergone considerable change. For much of that time, 'senility' was seen as an almost inevitable concomitant of ageing, and was usually attributed to atherosclerosis. In the postwar period, a concept of multi-infarct dementia emerged (Hachinski 1974), but at the same time Alzheimer's(More)
A diagnostic system for ICD-11 is proposed which commences with broad reorganization and simplification of the current categories and the use of clinically relevant specifiers. Such changes have implications for the positioning of diagnostic groups and lead to a range of possibilities for improving terminology and the juxtaposition of individual conditions.(More)
Depressive symptoms are common in medically ill patients although depressive disorders are considerably underdiagnosed and undertreated. Drug treatments for depression are reviewed in terms of a risk/benefit analysis. The main benefit is approximately to double the chance of recovery (from about 30 to 65%), with possible associated improvements in physical(More)
