Surgical treatment of esophageal leiomyoma located near or at the esophagogastric junction via a thoracoscopic approach

DISEASES OF THE ESOPHAGUS, Issue 2 2009
Z. G. Li
SUMMARY Esophageal leiomyoma can be enucleated safely and effectively by minimally invasive surgery. The laparoscopic approach has been a conventional option for this kind of tumor located near or at the esophagogastric (EG) junction. The aims of this study were to evaluate the surgical outcome of thoracoscopic resection of leiomyoma at the EG junction, and discuss factors affecting the incidence of postoperative gastroesophageal reflux. Fourteen patients who underwent thoracoscopic resection of esophageal leiomyoma located near or at the EG junction (<4 cm above the esophageal hiatus) from January 2002 to August 2007 were reviewed retrospectively. Tumor characteristics, surgical methods, and postoperative outcomes were evaluated. A left approach of video-assisted thoracoscopy was used in 13 patients; a right approach was used for the other patient, whose multiple tumors were located in the EG junction and mid-esophagus. Postoperative recovery was uneventful in all patients, with no mucosa leakage or other significant complications. Mean tumor size was 3.2 cm (1.2,6.0 cm). Of the 14 patients, two had serpiginous leiomyoma, two had multiple tumors, and the others had solitary tumors. Mean postoperative stay in hospital was 7 days (4,11 days). Postoperative dysphagia was not reported, although gastroesophageal reflux was noted in one patient. Thoracoscopic resection of esophageal leiomyomas near or at the EG junction is feasible, with a low prevalence of postoperative gastroesophageal reflux. [source]

Optimal sequence of landfills in solid waste management

OPTIMAL CONTROL APPLICATIONS AND METHODS, Issue 5-6 2001
Francisco J. André
Abstract Given that landfills are depletable and replaceable resources, the right approach, when dealing with landfill management, is that of designing an optimal sequence of landfills rather than designing every single landfill separately. In this paper, we use Optimal Control models, with mixed elements of both continuous-and discrete-time problems, to determine an optimal sequence of landfills, as regarding their capacity and lifetime. The resulting optimization problems involve splitting a time horizon of planning into several subintervals, the length of which has to be decided. In each of the subintervals some costs, the amount of which depends on the value of the decision variables, have to be borne. The obtained results may be applied to other economic problems such as private and public investments, consumption decisions on durable goods, etc. Copyright © 2001 John Wiley & Sons, Ltd. [source]

Management of cancer-associated thrombotic microangiopathy: What is the right approach?

AMERICAN JOURNAL OF HEMATOLOGY, Issue 4 2007
Theresa L. Werner
Abstract A 49-year-old Caucasian woman presented with features suggestive of thrombotic microangiopathy (TMA). She did not respond to treatment with repeated plasma exchange and corticosteroids. A bone marrow biopsy revealed presence of metastatic carcinoma. A limited autopsy revealed presence of breast cancer with rib metastases. Though severe deficiency of von Willebrand factor-cleaving protease was initially proposed as a key pathogenetic factor for thrombotic thrombocytopenic purpura, subsequent studies involving patients with cancer-associated TMA did not find as severe a deficiency of von Willebrand factor-cleaving protease as is seen in idiopathic cases of thrombotic thrombocytopenic purpura. Here we address one approach of management of these patients with cancer-associated TMA. Am. J. Hematol., 2006. © 2006 Wiley-Liss, Inc. [source]

The Role of Resource Access, Market Considerations, and the Nature of Innovation in Pursuit of Standards in the New Product Development Process

THE JOURNAL OF PRODUCT INNOVATION MANAGEMENT, Issue 5 2003
Arvind Sahay
Standards influence new product development (NPD) in high-technology markets. However, existing work on standards has focused exclusively on one aspect of standards,compatibility standards. This article has the following goals. First, we delineate the concept of customer interface standards as distinct from compatibility standards. This distinction is important from a product development and technology adoption perspective. Second, we propose and show that antecedent factors may motivate a firm differently about the emphasis that the firm should put on a type of standard (compatibility or customer interface) that it follows. For example, we propose that appropriability regime affects pursuit of customer interface standards and compatibility standards differently. Finally, we illustrate how resource access and the nature of the innovation also influence a firm's decision to pursue a standard type. Finally, we propose that pursuit of different standards (customer interface or compatibility) affects the NPD process in terms of (1) sourcing and dissemination of technology and (2) the customer utility for the product, which influences adoption. We collected perceptual data from a sample of marketing and technology managers in high-tech industries in the UK using both formative and reflective scales to measure the constructs. Analysis of the data using LISREL supports our contention that compatibility standards and customer interface standards are distinct constructs and that appropriability regime influences compatibility standards and customer interface standards differently. We also find that pursuit of compatibility standards helps a firm to create direct externalities pursuit of customer interface standards helps firms to develop indirect network externalities and technological advantage in the market. Our findings have the following implications. First, managers need to account explicitly for the difference between compatibility and customer interface standards, as resource allocation decisions during the NPD process will determine where a firm puts more focus. The choices made by the firm,as to whether it pursues compatibility standards or customer interface standards,will determine the type of advantage that it can gain in the market. Given a firm's situation at a point in time, a greater focus on one standard type rather than the other may be the right approach. Such choices will influence resource allocation in the product development process. [source]

Problems with the ,language-as-resource' discourse in the promotion of heritage languages in the U.S.A.

JOURNAL OF SOCIOLINGUISTICS, Issue 3 2005
Thomas Ricento
In the United States, language ,rights' have been tethered to ethnic or racial entitlements as a means to redress historical patterns of discrimination and exclusion. The perception that language ,rights' are about the redress of past wrongs has had negative effects on efforts to gain broad public support for the teaching and maintenance of languages other than English. The language-as-resource orientation (Ruiz 1984) is considered as an alternative to a language rights approach. However, analysis of texts produced by advocates of the heritage language movement reveals the shortcomings of the language-as-resource metaphor in advancing broad-based support for the teaching, maintenance, and use of minority languages in the U.S. While efforts to promote heritage language education as a national strategic priority may result in short-term governmental support, wider and more sustained popular support for such programs will require significant modifications in the underlying values and ideologies about the status and role of languages other than English in education and public life.
