RESUMO Objetivo: Avaliar a segurança e a viabilidade do uso de cateter pleural de longa permanência (CPLP) em pacientes com derrame pleural neoplásico (DPN). Métodos: Dados referentes a pacientes com DPN que receberam CPLP entre janeiro de 2014 e julho de 2015 foram colhidos prospectivamente. Todos os pacientes que receberam CPLP tinham expectativa de vida > 30 dias, em conformidade com as diretrizes de tratamento de DPN da Sociedade Torácica Britânica. Foram colhidos dados sobre sexo, idade, índice de massa corporal, local do câncer primário, tempo de drenagem com o CPLP, complicações relacionadas com o CPLP, tempo de internação hospitalar, recidiva do derrame pleural e ocorrência de pleurodese espontânea. Resultados: Dezenove pacientes receberam CPLP durante o período de estudo. A mediana de sobrevida global após a inserção do CPLP foi de 145 dias. A mediana de tempo de acompanhamento dos pacientes sobreviventes foi de 125 dias (variação: 53-485 dias), e a mediana de tempo decorrido entre a inserção e a remoção do cateter foi de 31 dias (variação: 2-126 dias). Houve complicações relacionadas com o CPLP em 5 pacientes (26,2%) e pleurodese espontânea em 8 (42,0%). Nesses 8 pacientes, o CPLP foi retirado entre os dias 30 e 126 em 4, e a pleurodese espontânea ocorreu nos primeiros 30 dias em 4. Conclusões: O uso de CPLP parece ser viável e seguro em pacientes com DPN.

ABSTRACT Objective: To evaluate the safety and feasibility of the use of indwelling pleural catheters (IPCs) in patients with malignant pleural effusion (MPE). Methods: We prospectively collected data from patients with MPE undergoing IPC placement between January of 2014 and July of 2015. All patients submitted to IPC placement had a life expectancy > 30 days, in accordance with the MPE treatment guidelines established by the British Thoracic Society. The data collected included gender, age, body mass index, primary cancer site, duration of IPC drainage, IPC-related complications, length of hospital stay, pleural effusion recurrence, and occurrence of spontaneous pleurodesis. Results: A total of 19 patients underwent IPC placement during the study period. Median overall survival after IPC insertion was 145 days. The median follow-up among the surviving patients was 125 days (range, 53-485 days), and the median time between catheter insertion and removal was 31 days (range, 2-126 days). There were IPC-related complications in 5 patients (26.2%), and spontaneous pleurodesis was achieved in 8 (42.0%). Among those 8 patients, the IPC was removed between days 30 and 126 in 4, and spontaneous pleurodesis occurred within the first 30 days in 4. Conclusions: The use of IPCs seems to be feasible and safe in patients with MPE.

Tumores glômicos são raras neoplasias benignas de tecidos moles. Relatamos o caso de um paciente de 32 anos de idade que apresentava atelectasia em lobo superior direito devido a um tumor endobrônquico. O paciente foi submetido a lobectomia superior direita e broncoplastia em cunha. O diagnóstico patológico foi de tumor glômico endobrônquico. Até onde sabemos, essa apresentação com atelectasia em lobo superior direito nunca foi relatada. O tumor glômico deve ser considerado no diagnóstico diferencial de lesões endobrônquicas que causam atelectasia lobar.

Glomus tumors are uncommon benign soft tissue neoplasms. We report the case of a 32-year-old male who presented with right upper lobe atelectasis due to an endobronchial tumor. The patient underwent right upper lobectomy and wedge bronchoplasty. The pathological diagnosis was bronchial glomus tumor. To our knowledge, this presentation (with right upper lobe atelectasis) has never before been reported. Glomus tumor should be considered in the differential diagnosis of endobronchial lesions causing lobar atelectasis.

O pericárdio pode ser afetado por doenças infecciosas, neoplásicas, inflamatórias e metabólicas. Muitas condições exigem tratamentos específicos, de forma que um diagnóstico preciso é importante. Assim, a biópsia do pericárdio tem um papel importante na avaliação dos derrames pericárdicos. A pericardioscopia oferece a vantagem da tradicional abordagem subxifóide ao permitir acesso a partes do pericárdio que não poderiam ser alcançadas através de palpação digital, bem como visibilização direta através da janela subxifóide ou toracoscopia. Reportamos o caso de um paciente com grande derrame pericárdico e massa mediastinal não-diagnosticada, em quem a pericardioscopia videoassistida foi fundamental no diagnóstico e tratamento da doença.

The pericardium can be affected by infectious, neoplastic, inflammatory and metabolic diseases. Many conditions require specific treatment and, consequently, an accurate diagnosis is important. Therefore, the pericardial biopsy has an important role in the evaluation of pericardial effusions. The pericardioscopy offers the advantage of the traditional subxiphoid approach, as it allows access to parts of the pericardium that would not be reached by digital palpation, as well as direct visualization through the subxiphoid window or thoracoscopy. We report the case of a patient with a large pericardial effusion and an undiagnosed mediastinal mass, in which video-assisted pericardioscopy was fundamental in the diagnosis and treatment of the disease.

OBJECTIVE: The purpose of this study was to compare spirometry data between patients who underwent single-lung or double-lung transplantation the first year after transplantation. INTRODUCTION: Lung transplantation, which was initially described as an experimental method in 1963, has become a therapeutic option for patients with advanced pulmonary diseases due to improvements in organ conservation, surgical technique, immunosuppressive therapy and treatment of post-operative infections. METHODS: We retrospectively reviewed the records of the 39 patients who received lung transplantation in our institution between August 2003 and August 2006. Twenty-nine patients survived one year post-transplantation, and all of them were followed. RESULTS: The increase in lung function in the double-lung transplant group was more substantial than that of the single-lung transplant group, exhibiting a statistical difference from the 1st month in both the forced expiratory volume in one second (FEV1) and the forced vital capacity (FVC) in comparison to the pre-transplant values (p <0.05). Comparison between double-lung transplant and single lung-transplant groups of emphysema patients demonstrated a significant difference in lung function beginning in the 3rd month after transplantation. DISCUSSION: The analyses of the whole group of transplant recipients and the sub-group of emphysema patients suggest the superiority of bilateral transplant over the unilateral alternative. Although the pre-transplant values of lung function were worse in the double-lung group, this difference was no longer significant in the subsequent months after surgery. CONCLUSION: Although both groups demonstrated functional improvement after transplantation, there was a clear tendency to greater improvement in FVC and FEV1 in the bilateral transplant group. Among our subjects, double-lung transplantation improved lung function.
