BACKGROUND There is much interest in reported associations between serum C-reactive protein and incident ischaemic heart disease. It is uncertain what this association represents. We aimed to assess the effect of confounding from a number of different sources in the Caerphilly Prospective Heart Disease Study and in particular whether the low grade(More)
Thirty-one patients who were in coma or persistent vegetative state two weeks after sustaining a severe head injury were entered into a coma arousal programme. The coma arousal protocol called for a sequence of vigorous multisensory stimulations to be applied to the patient by a relative for up to eight hours a day for seven days a week. An independent(More)
OBJECT Syringomyelia causes progressive myelopathy. Most patients with syringomyelia have a Chiari I malformation of the cerebellar tonsils. Determination of the pathophysiological mechanisms underlying the progression of syringomyelia associated with the Chiari I malformation should improve strategies to halt progression of myelopathy. METHODS The(More)
A prospective multi-institutional study was carried out to evaluate automated percutaneous discectomy in the treatment of lumbar disc herniations. Of the 327 patients who prospectively met the study criteria and were followed for longer than 1 year, 75.2% were successfully treated. When patients (n = 168) who prospectively did not meet the study criteria(More)
Duane's retraction syndrome (DRS) is a congenital eye movement disorder characterized by marked limitation or absence of abduction, variable limitation of adduction, and narrowing of the palpebral fissure with retraction of the globe on attempted adduction. We have recently recorded and quantitated ocular motility in five patients with unilateral DRS. In(More)
QUESTION Which imaging techniques most accurately differentiate true tumor progression from pseudo-progression or treatment related changes in patients with previously diagnosed glioblastoma? TARGET POPULATION These recommendations apply to adults with previously diagnosed glioblastoma who are suspected of experiencing progression of the neoplastic(More)
The sleep/wake patterns of 16 institutionalized demented women were visually monitored hourly for 14 consecutive days. Individual mean total sleep time varied markedly from 5.0 to 12.1 hours per 24 hours. Unexpectedly, amounts of day sleep and night sleep correlated positively, suggesting a general sleep tendency manifested throughout the 24-hour day.(More)
The minute eye movements of 4 sleeping subjects were studied with a piezo-electric strain-gauge transducer. The frequency and amplitude of ocular microtremor activity diminished during sleep. Activity increased after auditory stimulation and with the appearance of a K complex in the EEG. The ocular microtremor activity also increased with the onset of rapid(More)
