BACKGROUND A retrospective study of staged surgery for severe rigid scoliosis. The purpose of this study was to evaluate the result of staged surgery in treatment of severe rigid scoliosis and to discuss the indications. METHODS From 1998 to 2006, 21 cases of severe rigid scoliosis with coronal Cobb angle more than 80 degrees were treated by staged surgeries including anterior release and hal...
BACKGROUND The staged laparotomy in the operative management of emergency general surgery (EGS) patients is an extension of trauma surgeons operating on this population. Indications for its application, however, are not well defined, and are currently based on the lethal triad used in physiologically-decompensated trauma patients. This study sought to determine the acute indications for the sta...
BACKGROUND Bilateral total knee arthroplasty (TKA) is required for many patients. There are few studies comparing the overall costs of staged and simultaneous bilateral TKA. METHODS The Taiwan National Health Insurance Research Database (NHIRD) was searched, and the total medical costs of 452 patients who received simultaneous bilateral TKAs were compared with those of 690 who received staged...
Morphogenesis in the developing embryo takes place in three dimensions, and in addition, the dimension of time is another important factor in development. Therefore, the presentation of sequential morphological changes occurring in the embryo (4D visualization) is essential for understanding the complex morphogenetic events and the underlying mechanisms. Until recently, 3D visualization of embr...
This paper addresses difference flatness for structured LTI discrete-time systems. Two forms of necessary and sufficient conditions an output to be a structural flat are given. First, preliminary result algebraically defines in terms invariant zeros regardless whether system is or not. Next, the expressed graphical define output. Checking calls algorithms that have polynomial-time complexity co...
OBJECTIVES The purpose of this study was to examine the differences in in-hospital and longer-term mortality for ST-segment elevation myocardial infarction (STEMI) patients with multivessel disease as a function of whether they underwent single-vessel (culprit vessel) percutaneous coronary interventions (PCIs) or multivessel PCI. BACKGROUND The optimal treatment of patients with STEMI and mul...
