Middle-latency auditory evoked responses (MLRs) were recorded from infants and adults before and during open heart surgery. Hypothermia was induced through perfusion cooling by cardiopulmonary bypass. In infants deep hypothermia (to 15 degrees C nasopharyngeal temp.) was often followed by the induction of total circulatory arrest. In adults nasopharyngeal(More)
A computed tomographic image transfer system ('Image Link') was used to link scanners within the Oxford region, UK, to the regional neurosurgical service. 100 consecutive neurosurgical referrals were examined by this system; 43% of the emergency referrals did not require transfer, 31% were transferred electively, and 26% urgently. Most of the patients(More)
Exercise treadmill tests and ambulatory monitoring were used in a double-blind, placebo-controlled, double-dummy crossover comparison of nifedipine (10 mg, 3 times daily) and transdermal nitroglycerin (15 mg). All patients (n = 20) had chronic stable angina with symptomatic and silent events. All patients had 3 episodes of angina/week and 3 episodes of(More)
Primary endovascular reconstruction with flow diversion represents a fundamental paradigm shift in the technique of endovascular aneurysm treatment. Unlike coil embolization, often there remains residual post-procedural filling within the aneurysm with flow diverters, the curative reconstruction presumably occurring over a period of weeks. Thus,(More)
In order to determine whether the use of a smaller catheter would allow day-case cardiac catheterization by the femoral route, the performance of the Superflow (5F) and the 8F catheters was compared in 34 adults who underwent left ventriculography and coronary angiography. As shown by the significantly lower fluoroscopy time [2.8 +/- 1.2 min vs 4.5 +/- 2.7(More)
BACKGROUND Infantile colic is a common disorder, affecting around one in six families, and in 2001 was reported to cost the UK National Health Service in excess of £65 million per year (Morris 2001). Although it usually remits by six months of age, there is some evidence of longer-term sequelae for both children and parents.Manipulative therapies, such as(More)
A panel of 17 trainee maxillofacial surgeons viewed 23 cases of facial trauma, demonstrated on radiographs, axial CT images and three-dimensional (3D) reformatted CT images in a standardized viewing format under standard conditions. Their diagnostic interpretation, extraction of information relevant to surgical management and subjective evaluation of each(More)
We describe a new personal computer based image transfer and storage system. We prospectively assessed the uses and benefits of ImLink (Electronic Imaging Ltd.) in a regional neuroradiology department linked by the system to six referring district general hospitals. One hundred and fifty consecutive CT scans transferred by the system were analysed (142(More)
The primary purpose of this investigation was to evaluate postprocedure cognitive function associated with 3 distinct standard sedation regimens used for endoscopic procedures. A secondary aim was to identify complications requiring provider interventions. Subjects scheduled for colonoscopies were approached for enrollment the day of their procedure. A(More)
