- Hemangioma of the Rib(2011) ABRAO, Fernando Conrado; TAMAGNO, Mauro; CANZIAN, Mauro; FERNANDEZ, Angelo; BIBAS, Jacques; FERNANDES, Paulo Manuel Pego; JATENE, Fabio BiscegliAn asymptomatic 48-year-old woman presented to our hospital with a tumor of the rib incidentally diagnosed on a chest roentgenogram. The patient was investigated and underwent tumor resection of the chest wall. The pathologic study revealed that it was cavernous hemangioma. This tumor of the bone is a distinctly uncommon benign vascular tumor, generally occurring in the spine or skull. Hemangiomas involving the rib are even more rare, with only 22 cases described in the literature. However, we suggest that this tumor of the rib should be considered in the differential diagnosis, principally in asymptomatic patients.

- Giant multilocular thymic cyst in an HIV-infected adolescent(2011) TAMAGNO, Mauro; BIBAS, Benoit Jacques; BERNARDI, Fabiola; LIAN, Yu Ching; BAMMANN, Ricardo Helbert; FERNANDEZ, Angelo; JATENE, Fabio BiscegliA girl with vertically acquired HIV infection presented with a 6-month history of dyspnea and chest pain. Computed tomography of the thorax showed a heterogenous mass measuring 13 x 9 x 17 cm located in the anterior mediastinum. Complete surgical resection was accomplished with no complications. The final diagnosis was multilocular thymic cyst, a distinct pathologic entity that is morphologically distinguishable and unrelated to congenital thymic cyst.

Decannulation is the ultimate therapeutic goal for patients who undergo stenting because of inoperable benign tracheal stenosis. In this study, our objectives were to evaluate whether long-term airway stenting allows decannulation in patients with benign tracheal stenosis who were deemed inoperable and to identify possible predictive factors for successful decannulation (SD). Methods. Retrospective cohort study including all patients with inoperable benign tracheal stenosis who underwent tracheal stenting in our tertiary-care university-based institution from 1998 to 2008. For benign stenosis, we use only silicone stents (T tubes, Dumon stents, and Y stents). The main outcome was SD, which was defined as removal of the tracheal stent followed by absence of respiratory symptoms and no requirement for new dilation procedures for at least 6 months. A Kaplan-Meier curve was built to evaluate SD in 5 years, and we used a Cox model to evaluate predictors for a SD. Results. Ninety-two patients were included, and during the study period 21 were decannulated. However, 2 of them had to undergo new airway procedures and were considered to represent failure. Therefore, 19 patients were successfully decannulated. According to the Kaplan-Meier estimate, the SD rate in 5 years was 27.5%. The mean follow-up time after SD was 34.3 +/- 33.9 months (range, 6 to 108 months). Cox regression showed only 1 significant factor: tracheostomy before stent insertion caused a threefold increase in the likelihood of the patient remaining with a tracheal stent (p = 0.048). Conclusions. Tracheal stenting may be considered a curative therapeutic approach in as many as 27.5% of patients with inoperable benign tracheal stenosis.

- Effectiveness and safety of outpatient pleurodesis in patients with recurrent malignant pleural effusion and low performance status(2011) TERRA, Ricardo Mingarini; TEIXEIRA, Lisete Ribeiro; BIBAS, Benoit Jacques; PEGO-FERNANDES, Paulo Manuel; VARGAS, Francisco Suso; JATENE, Fabio BiscegliOBJECTIVES: 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 Status scores <= 70 but >30. All selected patients underwent pleural catheter placement (14 Fr) in an outpatient facility. When chest radiography revealed post-drainage lung expansion of >90%, pleurodesis (3 g of talc) was performed. Catheters were maintained until the daily output was <100 mL/day. The patients were evaluated in the first month and every three months thereafter for fluid recurrence, the need for additional procedures, and complications. RESULTS: During the study period (January 2005 to July 2007), 64 patients (24 men, 40 women), with an average age of 61.4 years, underwent elective chest tube drainage. Primary sites of the underlying malignancy were breast (27), lung (22), and others (15). Sixty-six pleural catheters were placed (bilaterally in 2 patients), and 52 talc pleurodesis procedures were performed. Fourteen patients had a trapped lung and were excluded from the trial. No complications were observed during catheter placement or pleurodesis. Post- pleurodesis complications included catheter obstruction (4 patients) and empyema (1). The average drainage time was 9.9 days. The recurrence rate observed in patients that were alive 30 days after pleurodesis was 13.9% (5/36 patients). Six patients required additional procedures after the pleurodesis. The average survival time was 101 days. CONCLUSION: In this study, talc pleurodesis was safely performed in an outpatient setting with good efficacy and a reasonable complication rate, thereby avoiding hospital admission.
