We report on a post-operative infection surveillance system which includes post-discharge follow-up, developed over five years in a district general hospital in the West Midlands, UK. The methods used for following up 667 patients undergoing one of five representative surgical procedures are described. Emergency, elective and day-case procedures are(More)
The effects of estrogen on cardiovascular risk factors have been less well defined in men than in women. We measured lipid and lipoprotein concentrations, lipoprotein particle size distributions, lipoprotein (a), homocysteine, and markers of thrombosis and fibrinolysis in 18 [corrected] healthy elderly men (age 74 +/- 3 years, mean +/- S.D.) before and(More)
This study prospectively evaluated the diagnostic accuracy of 64-slice computed tomographic angiography (CTA) in assessing the patency of coronary artery bypass grafts compared with invasive coronary angiography. In total 147 bypass grafts (100 venous grafts and 47 mammary artery grafts) were evaluated in 50 consecutive patients. Contrast-enhanced 64-slice(More)
OBJECT The authors performed spinal ultrasonography and/or magnetic resonance (MR) imaging in 20 consecutive newborns with spinal strawberry nevi. METHODS In 15 patients the strawberry nevi were isolated and in five they were associated with other cutaneous markers of occult spinal dysraphism (OSD). In four of five patients with additional cutaneous(More)
PURPOSE Although falls in people with Parkinson's disease (PD) associate with dual tasking and freezing of gait (FoG), it is not known whether falls during dual tasking are due to FoG. This study investigated the effects of a cognitive task on the occurrence of falls and FoG when subjects with PD step in response to a postural perturbation. METHODS Ten(More)
Feeding behavior in the species of captive chondrichthyans is studied to clarify the functional mechanisms responsible for feeding ecology. Kinematics and pressure in the buccal, hyoid and pharyngeal regions were quantified in Squalus acanthias, Chiloscyllium plagiosum and Leucoraja erinacea using sonomicrometry and pressure transducers. Means and(More)
