AIMS To assess antidepressant efficacy in juvenile depression. METHOD Systematic review and meta-analysis of randomised controlled trials (RCTs) comparing responses to antidepressants, overall(More)
Working memory is regulated by neurotransmitters in prefrontal cortex (PFC), including dopamine and norepinephrine. Previous studies of dopamine function in working memory have focused on the D1 and D2 receptors, with most evidence suggesting a dominant role for the D1 receptor. Since the dopamine D4 receptor is highly expressed in PFC, we hypothesize that(More)
In this study we investigate the association of cytochrome P450 enzyme CYP2D6, catechol-O-methyl transferase (COMT, Val158Met) and serotonin transporter promoter (5-HTTLPR) genotypes on change in cortisol concentration following 3, 4-methylenedioxy-methamphetamine (MDMA, 'ecstasy') consumption. Forty-eight subjects (30 males, mean age 23 years),(More)
OBJECTIVE The effect of minor orthopaedic day surgery (MiODS) on patient's mood. METHODS A prospective population-based cohort study of 148 consecutive patients with age above 18 and less than 65, an American Society of Anaesthesiology (ASA) score of 1, and the requirement of general anaesthesia (GA) were included. The Medical Outcomes Study - Short Form(More)
We hypothesised that genetically determined poor metabolism of 3,4-methylene dioxymetamphetamine (MDMA) due either to the presence of CYP2D6 genotypes giving absent or low CYP2D6 enzyme activity, or a COMT genotype predicting low COMT enzyme activity would be associated with a greater degree of MDMA-induced reduction in plasma sodium and osmolality than(More)
BACKGROUND The aim of this study was to examine whether there was an association between tardive dyskinesia (TD) and number of functional CYP2D6 genes. METHODS A Caucasian sample of 70 patients was recruited in 1996-1997 from South London and Maudsley National Health Service (NHS) Foundation Trust, UK. Subjects had a DSM-IIIR diagnosis of schizophrenia(More)
A recent meta-analysis of the efficacy of all types of antidepressants in juvenile major depressive disorder patients [1] urged that additional research be underta-ken to clarify the basis of limited responses in adolescents and children to antidepressant treatments considered standard in the treatment of adult major depressive disorder (MDD).(More)
BACKGROUND Cowden Syndrome is a rare autosomal dominant multiple hamartomatous condition, characterised by both benign and malignant tumours affecting multiple systems. CASE PRESENTATION We present a 47-year-old female patient with thigh pain that was diagnosed with Cowden syndrome 20 years ago and developed multiple and different skeletal metastases(More)
