Pulmonary Malakoplakia Associated with Peripheral Cysts in an Immunocompetent Patient: A Case Report.

Pulmonary malakoplakia is a rare lung lesion more frequently found in immunocompromised patients than in immunocompetent individuals. In this study, we report the challenging case of a young immunocompetent patient with an irregular pulmonary nodule with peripheral cysts who, after undergoing surgery, was diagnosed with malakoplakia. Due to the rarity of the disease and the similarity of this condition to malignant neoplasms, cytopathological or histopathological examinations are necessary for the correct diagnosis.

Computed tomography on lung cancer screening is useful for adjuvant comorbidity diagnosis in developing countries.

Purpose: The aim of this study was to analyse and quantify the prevalence of six comorbidities from lung cancer screening (LCS) on computed tomography (CT) scans of patients from developing countries.

Methods: For this retrospective study, low-dose CT scans (n=775) were examined from patients who underwent LCS in a tertiary hospital between 2016 and 2020. An age- and sex-matched control group was obtained for comparison (n=370).

Accuracy of multidetector computed tomography with maximum intensity projection technique in the assessment of fissure integrity.

Background: Bronchoscopic lung volume reduction (BLVR) is a potential treatment for patients with severe emphysema, performed through the placement of unidirectional endobronchial valves (EBVs). Their benefits are only achieved in patients that significantly reduce lobar volume, and it is mandatory that the fissures are complete. Fissure evaluation is preferably done by computed tomography, but little is known if its evaluation corresponds to the anatomical findings.

Pulmonary rehabilitation improves survival in patients with idiopathic pulmonary fibrosis undergoing lung transplantation.

This study was conducted to evaluate whether a pulmonary rehabilitation program (PRP) is independently associated with survival in patients with idiopathic pulmonary fibrosis (IPF) undergoing lung transplant (LTx). This quasi-experimental study included 89 patients who underwent LTx due to IPF. Thirty-two completed all 36 sessions in a PRP while on the waiting list for LTx (PRP group), and 53 completed fewer than 36 sessions (controls).

Video-assisted thoracoscopic surgery yields better outcomes than thoracotomy for anatomical lung resection in Brazil: a propensity score-matching analysis using the Brazilian Society of Thoracic Surgery database.

Objectives: The use of video-assisted anatomical lung resection is increasingly widespread for lung cancer and non-neoplastic diseases, showing excellent results. Nonetheless, a comparative analysis of the benefits of this technique has yet to be conducted in Latin America, a region with a completely different case mix from the USA or Europe. The purpose of this study was to compare the outcomes of video-assisted thoracoscopic surgery (VATS) and open thoracotomy (OT) for anatomical lung resection in patients included on the Brazilian Society of Thoracic Surgery (BSTS) database.

What is expected in lung function after lung transplantation due to end-stage pulmonary silicosis?

In this study, we aimed to determine the impact of lung transplantation (LTx) on pulmonary function tests (PFTs) and survival among patients with end-stage silicosis. We included patients with end-stage silicosis on the wait list for LTx, between January 1989 and July 2015 (N = 26). Sixteen of these patients received LTx; 10 were eligible, but did not undergo LTx (non-LTx) during the study period.

Anatomic pulmonary resection via video-assisted thoracic surgery: analysis of 117 cases at a referral center in Brazil.

Objective:: To describe our experience with video-assisted thoracic surgery (VATS) for anatomic pulmonary resection at a referral center for thoracic surgery in Brazil.

Methods:: All patients who underwent anatomic pulmonary resection by VATS between 2010 and 2015 were included. Clinical and pathological data, as well as postoperative complications, were analyzed.

Anatomic pulmonary resection by video-assisted thoracoscopy: the Brazilian experience (VATS Brazil study).

Objective: The objective of this study was to describe the results of anatomic pulmonary resections performed by video-assisted thoracoscopy in Brazil.

Methods: Thoracic surgeons (members of the Brazilian Society of Thoracic Surgery) were invited, via e-mail, to participate in the study. Eighteen surgeons participated in the project by providing us with retrospective databases containing information related to anatomic pulmonary resections performed by video-assisted thoracoscopy.

Twelve-year survival of the first living-donor pediatric lung transplantation in Brazil.

Objective: To report the long-term follow-up of the first living-donor lobar lung transplantation performed in Latin America.

Description: The patient was a 12-year-old boy with post-infectious obliterative bronchiolitis with end-stage pulmonary disease. He was on continuous oxygen support, presenting with dyspnea even during minimal activity.

Prognostic factors in lung transplantation: the Santa Casa de Porto Alegre experience.

Background: Lung transplantation (LT) has been established as a current therapy for selected patients with end-stage lung disease. Different prognostic factors have been reported by transplant centers. The objective of this study is to report our recent results with LT and to search for prognostic factors.

Diagnosis of invasive aspergillosis in lung transplant recipients by detection of galactomannan in the bronchoalveolar lavage fluid.

Background: Galactomannan (GM) detection in serum samples has been used to diagnose invasive aspergillosis (IA). Limited sensitivity has been observed in lung transplant recipients, for whom bronchoalveolar lavage (BAL) testing has been advocated. Because airway colonization with Aspergillus species occurs frequently in these patients, false-positive GM results have been reported if the cutoff validated for sera is used (i.

Surgical treatment of bronchial carcinoid tumors: a single-center experience.

Background: Bronchial carcinoid is an infrequent neoplasm with a neuroendocrine differentiation. Surgical treatment is the gold standard therapy, with procedures varying from sublobar resections to complex lung sparing broncoplastic procedures. This study evaluates the results of surgical treatment of bronchial carcinoids and its prognostic factors.

Large pulmonary artery pseudoaneurysm due to lung carcinoma: pulmonary artery pseudoaneurysm.

We present the case of a 54-year-old patient who presented to our institution 4 months after refusing surgical treatment for a right upper lobe cavitary carcinoma. Weight loss, hemoptysis, and worsening pulsatile chest pain were the complaints. Radiologic restaging surprisingly revealed a large pulmonary artery pseudoaneurysm occupying the whole cavity area.

Surgical treatment of benign tracheo-oesophageal fistulas with tracheal resection and oesophageal primary closure: is the muscle flap really necessary?

Objectives: Nowadays, despite the advances of the low-pressure high-volume cuffs, post-intubation tracheo-oesophageal fistula (TEF) still poses a major challenge to thoracic surgeons. The original technique includes interposition of muscle flaps between suture lines to avoid recurrence. It is not clear if this manoeuvre is indispensable and, in fact, we and others have faced problems with it.

Synchronous pulmonary and hepatic nodules in a patient with previous bronchogenic carcinoma: the relevance of histopathological confirmation.

The synchronous presentation of pulmonary and hepatic nodules in a patient with previously resected bronchogenic carcinoma raises suspicion of recurrence and mandates restaging. We present the case of a 71-year-old male with a history of lobectomy with pericardial resection and mediastinal lymphadenectomy (T3N0M0). At five years after the operation, he presented with a new pulmonary lesion.

Round pneumonia: a rare condition mimicking bronchogenic carcinoma. Case report and review of the literature.

Context: Round pneumonia is a condition usually described in children, with few reports addressing adult patients. It is an oval-shaped consolidation that, due to its radiological appearance, simulates bronchogenic carcinoma. Its evolution tends to be benign, although diagnostic dilemmas have sometimes required exploratory thoracotomy.

Surgical maneuvers for the management of bronchial complications in lung transplantation.

Background: Many advances have substantially improved the clinical results of lung transplantation. However, the incidence of bronchial complications is still high, with significant impact on survival and limited interventional strategies for complex cases. Our aim is to evaluate the surgical management of bronchial complications following lung transplantation.

Complications related to lobectomy in living lobar lung transplant donors.

Objective: To evaluate post-operative complications in living lobar lung transplant donors.

Methods: Between September of 1999 and May of 2005, lobectomies were performed in 32 healthy lung transplant donors for 16 recipients. The medical charts of these donors were retrospectively analyzed in order to determine the incidence of postoperative complications and alterations in pulmonary function after lobectomy.

Nonfunctioning paraganglioma of the aortopulmonary window.

Aortopulmonary paraganglioma is a rare tumor of the mediastinum. The only effective treatment is complete resection, which may pose a surgical challenge because of its proximity to the heart, great vessels, and trachea, often rendering a complete resection difficult to achieve. We report a case in which the tumor was excised under cardiopulmonary bypass and resulted in massive bleeding only controlled by means of packing the pleural cavity during 48 hours, known as damage control strategy.
