Pulmonary artery sarcoma is an uncommon neoplasm, and its clinical and radiological presentation usually simulates chronic thromboembolic disease. We present the case of a 77-year-old woman admitted with dyspnea, chest pain, and hemoptysis. A chest computed tomographic scan showed moderate right-sided pleural effusion and a saccular dilatation of the(More)
Attempts to reproduce inflammatory colitis have created many experimental models. Since the pioneer work of Morris et al. (1989), trinitrobenzenosulfonic (TNBS) solutions have been used with different dosages. The aims of this work were standardize the induction of colitis, evaluate the clinical and intestinal effects of different doses and verify the(More)
OBJECTIVES To evaluate the effectiveness and safety of pleurodesis carried out entirely on an outpatient basis in patients with recurrent malignant pleural effusions and Karnofsky Performance Status scores <70. METHODS This study was a prospective trial comprising patients with symptomatic recurrent malignant pleural effusion and Karnofsky Performance(More)
Primary tracheal malignant melanomas are uncommon neoplasms: only five cases have been reported. Different therapeutic approaches are described, with a short life expectancy observed. We report a case of a young woman with a primary tracheal malignant melanoma who underwent complete tracheal resection and is free of disease 4 years after surgical treatment.
In this article, the authors compare and illustrate the use of three static architecture-conformance techniques: dependency-structure matrices, source code query languages, and reflexion models. To highlight the similarities and differences between these three techniques, they describe how to apply some of the techniques' available supporting tools to(More)
Enteral nutrition (EN) and total parenteral nutrition (TPN) may provide life-sustaining therapy for surgical patients. The duration of nutritional therapy (enteral or parenteral) implies distinct access routes. We review the main aspects related to access routes for nutrient delivery. The enteral route, whenever feasible, is preferred. For EN lasting less(More)
This paper presents a domain-specific dependency constraint language that allows software architects to restrict the spectrum of structural dependencies that can be established in object-oriented systems. The ultimate goal is to provide architects with means to define acceptable and unacceptable dependencies according to the planned architecture of their(More)
Patients with short bowel syndrome (SBS) receiving total parenteral nutrition (TPN) have a high incidence of catheter-related sepsis, one of its major complications. The aim of this study was to correlate the length of remaining small bowel (RSB) with septic episodes related to the central venous catheter in a group of patients with severe SBS with home(More)
BACKGROUND Silver nitrate (SN) is an alternative to talc pleurodesis in patients with malignant pleural effusion (MPE). Nevertheless, SN complications have not been thoroughly investigated so far. OBJECTIVE To evaluate frequent adverse events (AE) of SN treatment at three different doses for pleurodesis in patients with MPE. The secondary objective was to(More)
Architectural erosion is a recurrent problem faced by software architects. Despite this fact, the process is usually tackled in ad hoc way, without adequate tool support at the architecture level. To address this issue, we describe the preliminary design of a recommendation system whose main purpose is to provide refactoring guidelines for developers and(More)
