Kikuchi-Fujimoto disease is characterized by fever and lymphadenopathy, usually localized in the cervical region. This disease principally affects young females. It can be confused with lymphoma, adenocarcinoma metastasis and tuberculosis. We report two cases of KikuchiFujimoto disease. In the first case, a 28-year-old female had been treated for(More)
We describe a case series of 35 patients with either benign (14) or malignant (21) tracheal stenosis who were treated using a novel silicone stent, the HCPA-1, designed to prevent migration. Between March 2001 and September 2008, 13 women and 22 men received 41 HCPA-1 stents. The median duration of stenting in benign cases was 457 days (range, 4-2,961(More)
PURPOSE To develop an animal model of diaphragmatic electrical stimulation able to generate an appropriate ventilatory support through the direct implantation of electrodes in the diaphragm (electroventilation). METHODS Six New Zealand female rabbits (2-3 kg) were placed on mechanical ventilation. Then, a laparotomy was performed in order to identify the(More)
BACKGROUND AND OBJECTIVES Learning curves have proved to be useful tools to monitor the performance of a worker on a new assignment. Those curves have been used to evaluate several medical procedures. The objective of this study was to evaluate the learning of orotracheal intubation (OTI) with the Truview EVO2 laryngoscope with the CUSUM learning curve. (More)
Squamous cell carcinoma of the esophagus is endemic in Rio Grande do Sul, the most southern state of Brazil, where the incidence reaches 27 out of 100,000 inhabitants per year. Palliative treatments, surgical or nonsurgical, impose lower mortality and lower costs. The choice of the best treatment for each patient depends on the neoplasia staging, and the(More)
A trachea is a tubular structure composed of smooth muscle that is reinforced with cartilage rings. Some diseases can cause sagging in smooth muscle and cartilaginous tissue. The end result is reduction (narrowing) of the trachea diameter. A solution to this problem is the use of tracheal stents, which are small tubular devices made of silicone. One is(More)
