BACKGROUND AND PURPOSE Among patients with spontaneous cervical artery dissections, the risk of recurrent arterial dissection is relatively low at 1% per year, but this risk may be higher for patients with a family history of arterial dissections. We compared the risk of a recurrent arterial dissection in patients with familial versus non familial disease.(More)
Cardiac transplantation is associated with increased prevalence of vertebral fractures, but the natural history of and risk factors for fracture after this life-saving procedure are unclear. We evaluated 47 patients (34 men and 13 postmenopausal women) before transplantation with spinal radiographs, determination of bone density by dual energy x-ray(More)
The IgG subclass response is determined by the type of bacteria producing the infection and by genetic factors of the host. Patients with a Helicobacter pylori infection develop a specific immune response that is mainly of the IgA and IgG class. We measured the IgG subclass response in 20 patients with chronic active gastritis without a history of duodenal(More)
Despite numerous advances in interventional radiology and vascular surgery, the clinician continues to be confronted with inoperable vascular disease. Previous studies have shown that ulceration associated with a transcutaneous oxygen pressure (tcPO2) of <20 mmHg is refractory to all attempts at healing. External pneumatic compression for the treatment of(More)
Pioneering centers report excellent results of Birmingham resurfacing arthroplasty. Results from pioneering surgeons are not usually reproduced when implants are used at other centers. We therefore studied patients' satisfaction, postoperative hip function, and survival of Birmingham hip resurfacing in a group, operated by nonpioneering surgeons. The median(More)
OBJECT The etiology of spontaneous cervical artery dissection is poorly understood; however, it may involve genetic and environmental factors. The purpose of this study was to determine whether seasonality of spontaneous cervical artery dissection exists. METHODS The seasonal pattern of spontaneous cervical artery dissection was analyzed in a group of 200(More)
We performed a prospective, randomised controlled trial to assess the differences in the use of a conventional suction drain, an Autologous Blood Transfusion (ABT) drain and no drain, in 168 patients. There was no significant difference between the drainage from ABT drains ( mean : 345 ml) and the suction drain (314 ml). Forty percent of patients receiving(More)
The purpose of this study was to compare functional outcome and survival of isolated acetabular, isolated femoral and both component revision after failure of primary Birmingham Hip Resurfacing. The Oswestry Outcome Centre prospectively collected data on 5000 hip resurfacing between 1997 and 2002. Of these, 182 hips were revised: 8% had revision of the(More)
OBJECTIVES To determine the safety and efficacy of intravenously administered phytonadione (vitamin K1) in patients on routine oral warfarin anticoagulation. PATIENTS AND METHODS This retrospective cohort study comprised adults who were taking warfarin, were not bleeding, and received intravenous phytonadione anticoagulation therapy before a diagnostic or(More)
Variable properties and limited availability are pitfalls in using cadaveric bones for implant stability tests. Artificial bones avoid these, but tailoring them to specific studies may be difficult. Stereolithography (SLA) techniques produce tailor-made bones with realistic geometries, but their lower Young's modulus might affect outcomes. We investigated(More)
