BACKGROUND: Pulmonary granulomas are sometimes resected because they resemble lung cancer and false-positive findings come through from positron emission tomography (PET) using 18fluorine-fluorodeoxyglucose (18F-FDG). Mycobacterial infection is a common cause of granulomas. OBJECTIVE: The purpose of this study was to evaluate the radiopathological features and the methods for identifying mycobacterial infections in granulomatous nodules resected from the lung. METHODS: Thirty-five solitary lesions resected because of suspected lung cancer were enrolled, including 22 nonfungal granulomatous lesions and 13 benign lesions as controls...

BACKGROUND: Data regarding pleural effusion due to pulmonary embolism (PE) are limited. OBJECTIVES: The aim of this study was to investigate the clinical characteristics of PE patients with pleural effusion caused by PE. METHODS: Patients with PE were retrospectively analyzed and divided into 2 groups based on computed tomography: a group with pleural effusion due to PE (effusion group) and a group without pleural effusion (control group)...

Necrotizing granulomatous diseases of the lungs are usually dependent on a narrow range of differential diagnoses. Tuberculosis (TB) is responsible for the largest number of cases, while necrotizing sarcoidosis is generally considered a rare and easily distinguishable disease substantially based on histological features. However, this entity has become a viable diagnosis in the absence of mycobacteria isolation or when a remarkable clinical improvement cannot be achieved with the combination of anti-TB drugs at full dosage...

BACKGROUND: The use of laryngeal mask airway (LMA) for fiberoptic bronchoscopy was first described in 1982. The LMA was found to be beneficial in operator view, flexibility, and also in maintaining stable oxygen saturation. Despite its advantages, the use of LMA has not become widespread. OBJECTIVE: The aim of this paper was to evaluate the safety of LMA-assisted bronchoscopy compared to standard nasal bronchoscopy. METHODS: We conducted a prospective randomized trial...

BACKGROUND: The German guideline on long-term oxygen therapy (LTOT) was published in 2008 by the German Respiratory Society (DGP), while the British Thoracic Society (BTS) published their most recent guideline in 2015. OBJECTIVES: The aim of the present article was to highlight the major areas of consensus and disagreement in the recently published BTS and DGP guidelines on LTOT. METHODS: The BTS and DGP guidelines were directly compared in terms of congruencies and differences...

BACKGROUND: Emphysema is characterised by airflow obstruction, hyperinflation, and resultant dyspnoea. It is worth investigating whether decompression improves lung mechanics and enhances quality of life (QoL). OBJECTIVES: The purpose of this study was to describe the feasibility and safety of creating a transthoracic pneumostoma to enable lung reduction. METHODS: A transthoracic 10-mm diameter Portaero Access Tube (Portaero™, Cupertino, CA, USA) was implanted via a third intercostal space incision in 15 severe emphysema patients [mean age 63 years, forced expiratory volume in 1 s 54% predicted, diffusing capacity for carbon monoxide 31% predicted, residual volume 246% predicted, Six-Minute Walk Test 296 m]...

BACKGROUND: New therapies have emerged in the treatment of pulmonary alveolar proteinosis (PAP) and, therefore, there is a real need to evaluate the efficacy of whole-lung lavage (WLL) in this rare disease. OBJECTIVES: The aim of this study was to assess the efficacy of WLL in patients with PAP. METHODS: We included 33 patients from 12 centers, which are members of the French-Speaking Thoracic Endoscopy Group, for analysis. Data collection concerned patients and disease characteristics, pulmonary function tests (PFTs) and technical information on the procedure...

We report a rare case of Takayasu's arteritis with isolated pulmonary artery stenosis in the presence of active hepatitis B and latent Mycobacterium tuberculosis infection in a middle-aged Asian woman who initially presented with severe dyspnea on exertion and recurrent syncope, occasional burning chest pains, and fatigue. Therapy of the active hepatitis B and latent M. tuberculosis infection together with a course of methotrexate led to a slight reversal of the symptoms, as angioplasty with or without stenting was not an option...

Asthma and chronic obstructive pulmonary disease (COPD) are prevalent conditions, and despite recent advances and multiple available therapies and interventions, there remains a significant unmet clinical need. In recent years, it has become clear that there is both significant heterogeneity within each of these conditions and additionally significant overlap in many of the clinical and inflammatory features. In parallel, useful clinical and immunological biomarkers which inform about prognosis and response to therapy have emerged in both asthma and COPD...

BACKGROUND: Little information exists on whether gender or asthma status modifies the effects of secondhand smoke (SHS) exposure on lung function. OBJECTIVE: To evaluate whether gender or asthma status modifies the association of SHS exposure with lung function. METHODS: A total of 6,740 children (average 11.6 years) were recruited from 24 districts of 7 cities in northeast China in 2012. SHS exposure included exposure to environmental and maternal smoking both in utero and during early childhood (postnatal)...

BACKGROUND: Polygraphy (PG) remains the standard method of assessing noninvasive ventilation (NIV) effectiveness. Built-in software (BIS) of recent NIV equipment provides estimates of some ventilator parameters, but their usefulness is unclear. OBJECTIVES: To assess the reliability of BIS compared with PG in a cohort of obesity hypoventilation syndrome (OHS) patients on NIV. METHODS: Thirty stable OHS patients on NIV were evaluated in an outpatient setting with simultaneous PG and BIS recordings...

BACKGROUND: The use of pulmonary function tests is primarily based on expert opinion and international guidelines. Current interpretation strategies are using predefined cutoffs for the description of a typical pattern. OBJECTIVES: We aimed to explore the predicted disease outcome based on the American Thoracic Society/European Respiratory Society (ATS/ERS) interpreting strategy. Subsequently, we investigated whether an unbiased machine learning framework integrating lung function with clinical variables may provide alternative decision trees resulting in a more accurate diagnosis...

BACKGROUND: In moderately to severely obese patients with obstructive sleep apnea (OSA), the effects of long-term positive airway pressure (PAP) treatment on cardiovascular risk are poorly defined. PURPOSE: To assess the effect of continuous positive airway pressure (CPAP) or noninvasive ventilation (NIV) on the occurrence of cardiovascular events in obese OSA patients. METHODS: We performed a noninterventional observational study in obese OSA patients recruited between 2007 and 2010 at the Sleep Center, University of Grenoble, treated with CPAP or NIV, and followed for 5...

BACKGROUND: The impact of hyperoxia on exercise limitation is still incompletely understood. OBJECTIVES: We investigated to which extent breathing hyperoxia enhances the exercise performance of healthy subjects and which physiologic mechanisms are involved. METHODS: A total of 32 healthy volunteers (43 ± 15 years, 12 women) performed 4 bicycle exercise tests to exhaustion with ramp and constant-load protocols (at 75% of the maximal workload [Wmax] on FiO2 0...

Capsule endoscope aspiration is an increasingly reported complication, potentially responsible for respiratory distress and asphyxia. This adverse event is primarily managed by rigid bronchoscopy when spontaneous expulsion does not occur. This complication is all the more detrimental to patients as it can delay or jeopardize further digestive exploration. We report direct repositioning of the capsule in the stomach at the same time as bronchoscopy, thus making second-line gastrointestinal endoscopy needless...

BACKGROUND: Even though the diagnosis of chronic obstructive pulmonary disease (COPD) is easy and based mainly on spirometry and symptoms, the prevalence of underdiagnosis is extremely high. The use of simple screening tools (e.g., questionnaires, hand-held spirometers) has been proved to be a simple method for case finding of COPD. Nevertheless the most appropriate target group of the general population has not been specified yet. OBJECTIVES: The aim of the present study was to compare 3 screening questionnaires among smokers aged >40 years in the primary care setting...
