OBJECTIVE Binaural hearing has been shown to support better speech perception in normal-hearing listeners than can be achieved with monaural stimulus presentation, particularly under noisy listening conditions. The purpose of this study was to evaluate whether bilateral electrical stimulation could confer similar benefits for cochlear implant listeners. (More)
UNLABELLED While statins are indicated to reduce blood cholesterol levels, they also have anti-inflammatory and immunomodulatory effects. Several observational cohort studies suggested that statins may improve survival and reduce complications in patients with sepsis. Recent randomized controlled studies in critically ill patients have been conducted and(More)
The pharmacokinetics and metabolism of R-apomorphine were determined in 10 patients with idiopathic Parkinson's disease after intravenous infusion of 30 micrograms.kg-1 in 15 min. Specifically, emphasis was on enantiomeric interconversion into S-apomorphine and on the formation of apocodeine and isoapocodeine, since these metabolites may interfere with the(More)
A series of experiments was run to assess bilateral cochlear implant users’ ability to fuse information presented dichotically. Two different methods of splitting the spectral information were investigated. In the first method, the odd-index channels were presented to one ear and the evenindex channels to the other ear. In the second method, the lower(More)
The phenomena observed during book retinoscopy include changes in the brightness of the reflex in response to changes in cognition. This experiment shows that the increase in luminance of the relfex that results from increased cognitive demand is mediated by accommodation. The luminance of the fundus reflex was monitored while subjects either read or added(More)
Analytical methods are described for the selective, rapid and sensitive determination of R- and S-apomorphine, apocodeine and isoapocodeine and the glucuronic acid and sulfate conjugates in plasma and urine. The methods involve liquid-liquid extraction followed by high-performance liquid chromatography with electrochemical detection. The glucuronide and(More)
OBJECTIVE To report experience with exposed cochlear implants in patients with risk factors that may contribute to flap failure. STUDY DESIGN Retrospective review. SETTING University-based tertiary referral center. PATIENTS Four patients with exposed cochlear implants who presented with various risk factors that compromise healing. INTERVENTION(More)
BACKGROUND Infection may complicate surgical patients' hospital admission. The effect of hospital-acquired infections (HAIs) on processes of care among surgical patients who died is unknown. AIM To investigate the effect of HAIs on processes of care in surgical patients who died in hospital. METHODS Surgeon-recorded infection data extracted from a(More)
