BACKGROUND The ProSeal laryngeal mask airway (PLMA) is a new laryngeal mask device with a modified cuff and a drainage tube. METHODS We assessed the PLMA in 300 anaesthetized adults either paralysed or breathing spontaneously. We assessed insertion characteristics, airway seal pressures, haemodynamic response to insertion, ease of gastric tube placement,(More)
Previous studies have reported elevated taste thresholds in depressed subjects, but those studies did not control for changes in response bias. The current study used signal detection analyses to address this shortcoming. Sucrose detection thresholds were measured (1) in subjects with high and low Hamilton Depression Rating Scale (HAM-D) scores who did not(More)
Posttraumatic stress disorder (PTSD) is associated with decreased hippocampal volume, but the relationship between trauma and brain morphology in the absence of PTSD is less clear. In this study, measures of brain integrity were determined by estimating gray and white matter regional brain volumes using structural magnetic resonance imaging in six patients(More)
BACKGROUND Though controversial, the risk of pulmonary aspiration during general anaesthesia in the immediate postpartum period appears low. The efficacy of the Proseal laryngeal mask airway was studied prospectively in a group of patients undergoing postpartum tubal ligation. METHODS The Proseal laryngeal mask airway was employed for airway management in(More)
Under conditions of maximal thermoregulatory peripheral dilatation, most healthy subjects (both Indian and European) showed raised blood flow in the fingertips (measured by laser Doppler flowmetry) where the skin temperature is only slightly lower than the core body temperature. Most borderline lepromatous (BL) leprosy patients had much colder fingers and(More)
Care coordination/case management models provide a method to measure expenditures within the context of health-care outcomes. High costs are predictable in a high skill, technology-intensive service industry such as academic medical centers. A care-coordination model provides a means to reduce the cost per case and influence patient satisfaction. In this(More)
OBJECTIVE A study of medical examiner records from suicide completers was designed to identify potential precipitating factors in the decision to commit suicide. METHODS Forensic data has been collected for a subset of suicide victims in Utah who completed suicide between 1996 and 2002. RESULTS Youth suicide completers appear to be undiagnosed for(More)
Most of the literature on bipolar disorder has focused on abnormalities of neurotransmitters rather than brain circuits. The few discussions of circuits have primarily focused on the limbic system. Evidence is accumulating, however, that basal ganglia-thalamic-cortical reentrant circuits play a major role in the affective, motor and cognitive symptoms of a(More)
