BACKGROUND Data on recurrence patterns following hepatectomy for colorectal liver metastases (CRLMs) and their impact on long-term outcomes are limited in the setting of modern multimodal management. This study sought to characterize the patterns of, factors associated with, and survival impact of recurrence following initial hepatectomy for CRLMs. METHODS A retrospective cohort study of pati...

Four groups of 20 dogs were anaesthetised by means of target-controlled infusions of propofol designed to achieve 2.5 microg/ml, 3.0 microg/ml, 3.5 microg/ml or 4.0 microg/ml of propofol in blood. The dogs' pulse rate and respiratory rate were recorded before premedication and induction, immediately after endotracheal intubation and three and five minutes later (times 0, 3 and 5, respectively),...

During a five-year period, a double-pin Roger Anderson apparatus, with pins perpendicularly placed in the second and third metacarpals and in the distal part of the radius, was applied in 130 patients with an unstable Colles fracture. Sixty of the 130 were followed for two years. Shortening was limited to a median of two millimeters and dorsal angulation, to a median of 3 degrees. Wrist dorsifl...

The retina has a high rate of oxygen consumption, and the retinal vessels are knoion to constrict with increased arterial oxygen tension and dilate ivhen arterial oxygen falls. In 10 subjects, measurement of retinal venous oxygen saturation by a photographic technique has shown an increase from 55 ± 8 per cent saturation breathing air to 82 ± 9 per cent breathing 100 per cent Os. This increase ...

'\J Out of 43 ruptures of the spleen 14, or 32*5 per cent, were accompanied by injuries of other orgaus, during the 9 years I have been considering. Of these, 5 or 35'7 per cent., were complicated with ruptures of the liver; 3, or 21*4 per cent., with those of the left kidney; 1, or 7*1 per cent., with laceration of the brain ; 1, or 7*1 percent., of the stomach ; 1, or 7*1 percent., with lacer...

BACKGROUND Private hospitals' activities are not routinely reported, so what services they provide and for whom is not known. This study describes the clientele and case-mix of independent hospitals in England and Wales in 1997-1998. METHOD Person, clinical and funding data were collected on samples of patients admitted to 215 of 221 independent hospitals open in 1997-1998. Sample numbers wer...

BACKGROUND With an increased use of magnetic resonance imaging, the indications for endoscopic retrograde cholangiopancreatography (ERCP) have changed. Consequently, the patterns and factors predictive of complications after ERCP performed during current routine clinical practice are not well known. METHODS A prospective multicentre cohort study was undertaken in 11 Norwegian hospitals. Compl...

BACKGROUND Long-term levodopa usage in Parkinson's disease (PD) patients is known to cause several motor complications. It may be related to several factors such as levodopa dosage, duration of treatment and severity of disease. OBJECTIVE To study the prevalence of levodopa motor complications and associated factors in Thai Parkinson's disease patients. MATERIAL AND METHOD The authors prosp...
