BACKGROUND A paediatric anaesthesia information leaflet was produced to address preoperative parental anxiety and to facilitate informed parental consent. METHODS An audit was undertaken to assess the impact of introducing the leaflet. This addressed the information needs and expectations of parents of children undergoing anaesthesia, parental(More)
This study examined the impact of perceptual load on the processing of unattended threat-relevant faces. Participants performed a central letter-classification task while ignoring irrelevant face distractors, which appeared above or below the central task. The face distractors were graded for affective salience by means of aversive fear conditioning, with a(More)
BACKGROUND AND PURPOSE Imaging methods are currently being optimized in an attempt to assess and monitor angiogenesis in vivo. The purpose of this investigation was to determine whether areas of apparently increased tumor vascularity, as identified on 8-T gradient-echo (GE) imaging of a known glioblastoma multiforme (GBM), corresponds to foci of increased(More)
The impact of trait anxiety and perceptual load on selective attention was examined in a fear conditioning paradigm. A fear-conditioned angry face (CS+), an unconditioned angry face (CS-), or an unconditioned face with a neutral or happy expression were used in distractor interference and attentional probe tasks. In Experiments 1 and 2, participants(More)
Adaptive behavior relies on the ability to effectively and efficiently ignore irrelevant information, an important component of attentional control. The current research found that fundamental difficulties in ignoring irrelevant material are related to dispositional differences in trait propensity to worry, suggesting a core deficit in attentional control(More)
The work of nine Naval anaesthetists deployed with the Task Force during the Falklands campaign is described. The anaesthetists worked in a field hospital (Ajax Bay), a hospital ship (SS Uganda), a troop ship (SS Camberra), aircraft carriers (HMS Hermes and HMS Invincible) and a Royal Fleet Auxiliary (Tidespring). The problems of staffing and providing the(More)
An infant with Timothy syndrome, a congenital syndrome resulting in a long QT interval and high risk of death in childhood, is presented along with his perioperative management. Characteristic life-threatening arrhythmias thought to be caused by excess sympathetic stimulation secondary to an arterial tourniquet are described.
Soil is an important reservoir of PCDD/PCDF, which can be released when environmental conditions change. Fire is an extreme event that can increase the surface temperatures of soil substantially, yet little is known of the role soil plays in the emission of PCDD/PCDF. Soil containing native PCDD/PCDF was fortified with a mixture of mass labelled PCDD/PCDF(More)
