BACKGROUND: Idiopathic pulmonary fibrosis (IPF) is a lethal lung disease of unknown etiology. Patients present loss of lung function, dyspnea and dry cough. Diagnosis requires compatible radiologic imaging and, in undetermined cases, invasive procedures such as bronchoscopy and surgical lung biopsy. The pathophysiological mechanisms of IPF are not completely understood. Lung injury with abnormal alveolar epithelial repair is thought to be a major cause for activation of profibrotic pathways in IPF...

A 15-year-old boy presented to us with a 4-month history of fever with worsening dyspnea since 1 month. His contrast-enhanced computed tomography scan of the thorax showed bilateral endobronchial lesions with complete collapse-consolidation of the left lung and partial collapse of the right lower lobe. His fiberoptic bronchoscopy guided biopsy had been reported in outside hospital as a neuroendocrine tumor. Due to worsening breathlessness, he had to be intubated. We repeated the endobronchial biopsy and combined with outside slides and blocks, was diagnosed to have an anaplastic lymphoma kinase-1 positive anaplastic large cell lymphoma (ALCL)...

BACKGROUND: Peripheral pulmonary lesions (PPLs) pose a diagnostic challenge, and the optimal investigation in many such cases remains unclear. Computed tomography (CT)-guided percutaneous needle biopsy (CT-PNB) has been the modality of choice for such lesions with a high diagnostic accuracy but with high rates of pneumothorax. Endobronchial ultrasound (EBUS) with a radial probe is an alternate diagnostic modality with increased diagnostic yield of bronchoscopy in the evaluation of PPL...

Our objective was to evaluate the efficacy of a standardised work-up in the diagnosis of pleural tuberculosis (TB) that included fibreoptic bronchoscopy and medical thoracoscopy. A consecutive series of 52 pleural TB patients observed during the period 2001-2015 was evaluated retrospectively. 20 females, mean (range) age 39.7 (18-74) years, and 32 males, mean (range) age 45.75 (21-83) years, were included (28 non-EU citizens (53.8%)). The diagnosis of TB infections was established by identification (using stains, culture or molecular tests) of Mycobacterium tuberculosis in the pleura, sputum and/or bronchial specimens, or by evidence of caseous granulomas on pleural biopsies...

Case summary: A 12-year-old female spayed domestic shorthair cat presented with history of a long-term chronic cough that had worsened during the previous 2 months. Thoracic radiographs revealed numerous mineral opacities throughout the lung fields. Multiple bronchial plugs of pale yellow material were present on bronchoscopy, consistent with broncholithiasis. Bronchoalveolar lavage cytology revealed a mild neutrophilic inflammation and bacterial culture was negative. The cat was diagnosed with chronic inflammatory lower airway disease and broncholithiasis, suspected to be due to mineralisation of secretions in the bronchial lumen...

This Phase I study assessed the intrapulmonary pharmacokinetic profiles of relebactam (MK-7655), a novel ß-lactamase inhibitor, and imipenem. Sixteen healthy subjects received 250 mg relebactam with 500 mg imipenem/cilastatin, given IV every 6 hours for 5 doses, and were randomized to bronchoscopy/broncho-alveolar lavage at 0.5, 1, 1.5, or 3 hours after the last dose (4 subjects per time point). Both drugs penetrated the epithelial lining fluid (ELF) to a similar degree, with profiles similar in shape to the corresponding plasma profiles and apparent terminal half-lives in plasma and ELF, respectively, of 1...

We describe a patient with untreated hepatitis C virus (HCV) infection presenting with pulmonary renal syndrome. He rapidly developed bilateral lung infiltrates and respiratory failure, and bronchoscopy confirmed acute alveolar haemorrhage secondary to cryoglobulinaemic vasculitis. Early bronchoscopy to confirm the diagnosis and consequent institution of immunosuppressive therapy led to excellent outcomes, which otherwise is reported in the literature to carry significant mortality. Therefore, in patients with HCV presenting with bilateral lung infiltrates, physicians must maintain a high degree of clinical suspicion for alveolar haemorrhage secondary to cryoglobulinaemic vasculitis...

Aztreonam, a broad-spectrum monobactam, is typically reserved for multidrug resistant (MDR) infections. Pharmacokinetic (PK) data to guide dosing in children, however, are limited to healthy volunteers or nonintensive care unit (ICU) patients. Impaired antibiotic delivery into tissue remains a major concern and may explain the high morbidity and mortality associated with MDR infections. Therefore, evaluating the PK changes in pediatric ICU patients is necessary to elucidate the most appropriate antimicrobial regimen...

We herein report a case of lung metastases with unusual radiological appearances that mimicked those of chronic airway infection, causing diagnostic difficulty. A 60-year-old woman who underwent liver transplantation from a living donor was incidentally diagnosed with bile duct adenocarcinoma after a histopathological analysis of her explanted liver. Six months later, chest computed tomography (CT) revealed bilateral bronchogenic dissemination that had gradually worsened, suggesting chronic airway infection...

BACKGROUND: With the application of high resolution computed tomography (CT), a large number of peripheral lung lesions were found. It put forward new challenge on clinical diagnosis and treatment for these peripheral lung lesions. Electromagnetic navigation bronchoscopy (ENB) and radial endobronchial ultrasound probe (R-EBUS) are new technologies used for the diagnosis of peripheral lung lesions. The aim of this study is to explore the application value of ENB combined with R-EBUS in the diagnosis of peripheral pulmonary lesions...

BACKGROUND: Staphylococcus aureus (S. aureus) may be related to more rapid progression of cystic fibrosis (CF) lung disease. METHODS: In the AREST CF cohort study, children diagnosed with CF undergo annual bronchoscopies with bronchoalveolar lavage and ultra-low-dose, chest computed tomography (CT) up to 6-years-old. Spirometry was assessed 3-monthly from the age of 4years. Associations between de novo S. aureus acquisition before school age and CT and lung function at ages 5-7years were investigated...

BACKGROUND: Pulmonary tumor thrombotic microangiopathy is a special type of tumor thromboembolism. We report the case of a patient who developed pulmonary tumor thrombotic microangiopathy with alveolar hemorrhage. Almost all patients with pulmonary tumor thrombotic microangiopathy die within 1 week of the onset of dyspnea; however, the prognosis in this case was better, with 10 weeks of survival from presentation. CASE PRESENTATION: A 62-year-old Japanese man was referred to our hospital with a 4-week history of dyspnea on exertion and severe pulmonary hypertension...

BACKGROUND: The use surgical simulation across all subspecialties has gained widespread adoption in the last decade. A number of factors, including the small number of trainees, identified gaps in surgical skill training from cross-sectional surveys, increased national collaboration, and support from the national specialty committee identified a need to construct a surgical skills "bootcamp" in thoracic surgery in Canada. OBJECTIVE: The goals of the surgical skills bootcamp, as identified by the residency training program directors and the national specialty committee were to create a national, centralized, simulation-based skills workshop that focused on key foundational procedures within thoracic surgery, particularly those identified as areas of weakness by former residents; to smooth the transition to intraoperative teaching; to provide exposure to important but not necessarily universally available procedures such as advanced endoscopy; to teach non-medical expert competencies, and lastly to provide a venue for networking for residents across the country...

RATIONALE: Endobronchial hamartoma, the most common benign lung tumor, is located in the bronchus, and it easily mimics lung cancer or bronchial metastasis. Endobronchial hamartoma can cause coughing, hemoptysis, and pulmonary infection; thus, it should be treated right away by surgery or fiberoptic bronchoscopy. PATIENT CONCERNS: We report a rare case of endobronchial hamartoma in which the clinical symptoms and imaging overlapped strongly with malignant lung tumor contralateral endobronchial metastasis...
