BACKGROUND Electrocautery is used increasingly for tissue dissection, although fears of excessive scarring and poor wound healing have curtailed its widespread use for skin incision. This study compared electrosurgical incision with traditional scalpel incision. METHODS One hundred patients requiring elective midline laparotomy were randomized(More)
The presence of periprosthetic malignancy in proximity to arthroplasty implants has been infrequently reported. We present the clinical, radiographic, and pathological features of three patients in whom loosening and failure of total hip arthroplasties occurred secondary to malignant infiltration. They consisted of a 66-year-old man with the first(More)
Providing a long-lasting total hip arthroplasty for patients younger than 50 years remains one of the greatest challenges for modern arthroplasty surgery. We retrospectively reviewed 221 patients younger than 50 years who underwent 299 uncemented total hip arthroplasties from 1983 to 2000. We assessed 5- to 15-year survival with revision as the endpoint.(More)
Ischaemia-reperfusion injury (IRI) is caused by endothelial and subendothelial damage by neutrophil-derived oxidants. Vitamin C is an antioxidant which attenuates endothelial injury after IRI. Our aim was to evaluate the effect of oral vitamin C in the prevention of IRI in skeletal muscle. We used a model of cross-clamping (3 hours) and reperfusion (1 hour)(More)
A 66-year-old woman presented with a 3-day history of classical features of large bowel obstruction. At emergency laparotomy, the transverse colon and splenic flexure were located in the left hemithorax. The entire left hemidiaphragm was absent, and there were no diaphragmatic remnants visible. This is the oldest reported case of an absent hemidiaphragm.(More)
Dedicated skate parks have led to an increase in pediatric fractures referred to the authors' unit. The authors performed a prospective analysis of all patients presenting to their unit with fractures sustained while Rollerblading or skateboarding over a 5-month period. Epidemiologic data, user experience, wearing of protective gear, place of injury, and(More)
PURPOSE To report outcomes in 10 patients who underwent dynamic "S" Quattro external fixation for complex fractures of the base of the thumb. METHODS Nine men and one woman aged 18 to 69 (mean, 31) years underwent "S" Quattro external fixation for complex fractures of the base of the thumb. The dominant hand was involved in 8 patients. Three patients had(More)
OBJECTIVES to evaluate vitamin C supplementation in the prevention of ischaemia-reperfusion (I-R) induced acute lung injury. DESIGN Sprague-Dawley rats (n =6/group) were randomised into Control, I-R and I-R pretreated with vitamin C (3.3 g over 5 days). Ischaemia-reperfusion injury was induced by 30 minutes infrarenal aortic cross-clamping and 120 minutes(More)
BACKGROUND The therapeutic efficacy of interleukin-2 (IL-2) has been limited by a dose-dependent vascular leak syndrome. This may be related to neutrophil-mediated endothelial injury. Taurine has been shown to decrease this injury in vitro. This study investigates the role of taurine in preventing IL-2-induced lung injury, and the role of(More)
Compartment syndrome is a unique form of ischaemia of skeletal muscle which occurs despite patency of the large vessels. Decompression allows the influx of activated leucocytes which cause further injury. Vitamin C is a powerful antioxidant which concentrates preferentially in leucocytes and attenuates reperfusion-induced muscle injury. We have evaluated(More)
