BACKGROUND Despite significant advances in organ preservation, surgical techniques and perioperative care, primary graft dysfunction is a serious medical problem in transplantation medicine in general and a specific problem in patients undergoing lung transplantation. As a result, patients develop lung edema, causing reduced tissue oxygenation capacity, reduced lung compliance and increased req...

Objective: Prospective evaluation of early stent-graft repair of acute traumatic aortic rupture. Methods: Twelve patients with acute traumatic aortic rupture of the descending aorta, out of a series of 337 endovascular aortic procedures, were treated by implantation of selfexpanding stent-grafts. The procedures were performed within a mean post-injury time-period of 5 ^ 7 days (median: 1 day). ...

Inducible NO synthase (iNOS) is expressed by macrophages and smooth muscle cells in atherosclerotic lesions. Previously, we have established a mouse model for vein graft arteriosclerosis by grafting autologous jugular veins or vena cava to carotid arteries. Using this model, we studied the role of iNOS in the development of vein graft arteriosclerosis in iNOS(-/-) mice. Four weeks after graftin...

background: age is one of the most important factors that have consistently emerged as the most potent predictors of mortality and morbidity after coronary artery bypass graft (cabg) surgery. however, early results of cabg in young patients in comparison with elderly ones have been different in previous surveys. the aim of this study was to compare short-term mortality and morbidity in young ve...

PURPOSE To review the treatment outcome of patients with neglected femoral shaft fractures. METHODS Records of 22 men and 3 women aged 20 to 55 (mean, 36) years who underwent open interlocking nailing and bone grafting for neglected (2-month-old or more) closed femoral shaft fractures were reviewed. 21 had nonunion and 4 had malunion. All patients had deformed, shortened, and wasted lower lim...

PURPOSE This case report discusses 2 patients who required implant placement in the atrophic posterior maxilla to support a fixed prosthesis with the least invasive and shortest procedure. MATERIALS AND METHODS The reference standard of care would be to perform sinus augmentation with an autologous bone graft through the lateral approach with delayed implant placement. However, in these cases...

Purpose The purpose of this review is to compare the clinical and radiological outcomes between open and closed wedge distal femoral varus osteotomy (DFO). Methods A literature search of online databases (MEDLINE, EMBASE, and Cochrane Library database) was made in addition to manual search of major orthopedic journals. Data were searched from the time period of January 1990 to October 2016. A...

Repair of fractures involves a sequence of dynamic events which ultimately restores the integrity of the bone and its biomechanical properties. In some cases healing is compromised, leading to delayed union or nonunion. It is estimated that 10% of the fractures which occur annually will require further surgical procedures because of impaired healing. The preferred management of nonunion and bon...

Human neural transplants are being developed to treat Parkinson's disease. Previous characterization of human transplants focused on neuronal development, while little is known of the interaction between the transplant and its environment, among which blood is of prime importance. We evaluated here the formation of blood vessels in human neural xenografts placed into the brain of rats immunosup...

BACKGROUND To date, no studies have been published in which histomorphometric data from a large group of patients comparing various biomaterials for sinus floor augmentation procedures were evaluated. MATERIALS AND METHODS A meta-analysis of the English literature from January 1993 till April 2009 was carried out. Out of 147 titles, according to our criteria, 64 articles were selected for ana...
