OBJECTIVE The pain following thoracic surgery and trauma is often refractory to conventional analgesic strategies. However, it shares key characteristics with neuropathic pain which gabapentin, an anticonvulsant, has been proven to effectively treat. To our knowledge, this is the first prospective study assessing the use of gabapentin in cardiothoracic(More)
The central role of lung ischaemia-reperfusion injury in pulmonary dysfunction after cardiac surgery, particularly thoracic organ transplantation, has been well recognised. Lung tissue necrosis after prolonged ischaemia is known to worsen lung function, which was believed to be due largely to adjacent tissue inflammation. Recent studies suggest that lung(More)
Malignant pleural effusion is a common condition and often presents a challenge for treatment. We report our experience from a single institution with the use of video-assisted thoracoscopic surgery (VATS) in the management of malignant effusions. From September 1992 to April 1995, 69 patients (31 men, 38 women; age range, 38 to 76 years) underwent(More)
OBJECTIVE Major surgery is immunosuppressive and could have an impact on postoperative tumor immunosurveillance and recurrence in cancer patients. Low circulating levels of insulin growth factor binding protein (IGFBP)-3 have been linked to advance prostate and the development of colonic cancers. This prospective study examined the early postoperative(More)
OBJECTIVES The techniques of performing coronary revascularization without cardiopulmonary bypass are rapidly evolving. However, concern remains regarding the accuracy of coronary artery anastomoses performed on the beating heart. This report reviews the use of intraoperative angiography in the critical appraisal of "off-pump" coronary artery bypass graft(More)
BACKGROUND Angiogenic factors following oncological surgery is important in tumor recurrence. Vascular endothelial growth factor (VEGF), angiopoietin 1 (Ang-1), Ang-2, soluble VEGF-receptor 1 (sVEGFR1) and sVEGFR2 may influence angiogenesis. This prospective study examined the influence of open and video-assisted thoracic surgery (VATS) lung resections for(More)
Challen and co-workers fail to mention that PMEWS is a graded score for each parameter, rather than the categorical scores used in CURB, making PMEWS inherently more complex to use, especially outside the hospital. In addition, CRB-65 can be calculated without any laboratory or oximetric results. The medical early warning score has the potential advantages(More)
OBJECTIVES Use of titanium prostheses for reconstructing chest wall defects following major chest wall resections is rapidly increasing in popularity. Previously, complications including prosthesis fracture have been reported for the system secured to the rib ends using clips following chest wall reconstruction and pectus excavatum repair. By contrast,(More)
