BACKGROUND AND OBJECTIVE: Target lobar volume reduction (TLVR) is an important efficacy outcome measure for bronchoscopic lung volume reduction (BLVR) treatment using one-way endobronchial valves (EBV) in patients with severe emphysema. The commonly used cut-off value for TLVR that expresses a perceivable clinical benefit is -350 mL. However, a scientifically determined minimal important difference (MID) for TLVR never has been published. The objective of the present study was to determine the MID for TLVR on HRCT in patients who were treated with EBV...

PURPOSE: The management of orbital blowout fractures (BOFs) is controversial: the evaluation of diplopia is the most important criterion for planning whether to undertake surgery. Our aim was to determine CT findings that may suggest the presence of diplopia when patients with BOFs cannot be adequately examined to plan an orbital repair. METHOD AND MATERIALS: We retrospectively evaluated CT of all patients presented to our Emergency Department for blunt craniofacial trauma (N = 3334) from January 2014 to March 2016, selecting patients with CT-demonstrated BOFs...

BACKGROUND: Studies have demonstrated both positive and negative effects of obesity on clinical outcomes in chronic obstructive pulmonary disease (COPD). In other chronic diseases, fat location is differentially associated with disease outcomes; however, this relationship has not been well studied in COPD. OBJECTIVE: To determine if fat location explains the differential association of body mass index (BMI) with clinical outcome measures in smokers. METHODS: Baseline and 6-year chest computed tomography scans from 68 current and former smokers were used to quantify mediastinal and subcutaneous fat...

BACKGROUND: COPD is a pulmonary disorder often accompanied by cardiovascular disease (CVD), and current treatment of this comorbidity is suboptimal. Systemic inflammation in COPD triggered by smoke and microbial exposure is suggested to link COPD and CVD. Mesenchymal stromal cells (MSC) possess anti-inflammatory capacities and MSC treatment is considered an attractive treatment option for various chronic inflammatory diseases. Therefore, we investigated the immunomodulatory properties of MSC in an acute and chronic model of lipopolysaccharide (LPS)-induced inflammation, emphysema and atherosclerosis development in APOE*3-Leiden (E3L) mice...

BACKGROUND AND OBJECTIVE: Chronic exposure to biomass smoke (BS) can significantly compromise pulmonary function and lead to chronic obstructive pulmonary disease (COPD). To determine whether BS exposure induces a unique phenotype of COPD from an early stage, with different physiopathological features compared with COPD associated with smoking (cigarette-smoke (CS) COPD), we assessed the physiopathology of early COPD associated with BS exposure (BS COPD) by incorporating spirometry, high-resolution computed tomography (HRCT) imaging, bronchoscopy and pathological examinations...

BACKGROUND AND OBJECTIVE: Matrix degradation is a key feature of chronic obstructive pulmonary disease (COPD). Desmosine and isodesmosine (desmosines) are excreted in urine following matrix degradation. The main purpose of this study was to investigate the association between computed tomography (CT) emphysema indices and urinary desmosines in patients with COPD. METHODS: A total of 152 subjects were selected from the Korean Obstructive Lung Disease cohort. Their urine samples were assayed for desmosines using liquid chromatography-tandem mass spectrometry (LC-MS/MS) methods...

Introduction Performing a routine postoperative chest X-ray (CXR) after general thoracic surgery is daily practice in many thoracic surgery departments. The quality, frequency of pathological findings and the clinical consequences have not been well evaluated. Furthermore, exposure to ionising radiation should be restricted to a minimum and therefore routine practice can be questioned. Methods As a hospital standard, each patient was given a routine CXR after opening of the pleura and inserting a chest tube...

PURPOSE: Secondary spontaneous pneumothorax (SSP) is difficult to treat by itself and due to its association with serious underlying diseases. It has a high rate of recurrence and often requires extended hospitalization. Therefore, we evaluated the outcome and risk factors associated with recurrence and extended hospitalization. METHODS: We retrospectively examined 61 patients with SSP, and evaluated the patients' characteristics, underlying diseases, introduction of home oxygen therapy, Brinkman index, and X-ray imaging findings to determine the risk factors for recurrence and extended hospitalization...

Chronic obstructive pulmonary disease (COPD) has no curative treatment, and in moderate to advanced stages, functional parameters and quality of life are affected. Lung volume reduction improves respiratory parameters and quality of life of these patients. Endoscopic lung volume reduction is a minimally invasive procedure that uses endobronchial valves or coils. Valves are unidirectional, blocking the air from entering the target lobe during inspiration, allowing the exit of air and secretions during expiration...

INTRODUCTION: Chest trauma may be blunt or penetrating and the chest is the third most common trauma region. It is a significant cause of mortality. Multidetector computed tomography (MDCT) has been an increasingly used method to evaluate chest trauma because of its high success in detecting tissue and organ injuries. Herein, we aimed to present MDCT findings in patients with blunt and penetrating chest trauma admitted to our department. METHODS: A total of 240 patients admitted to the emergency department of our hospital between April 2012 and July 2013 with a diagnosis of chest trauma who underwent MDCT evaluations were included...

Little is known about the human lung lipidome, its variability in different physiological states, its alterations during carcinogenesis and the development of pulmonary emphysema. We investigated how health status might be mirrored in the lung lipidome. Tissues were sampled for both lipidomic and histological analysis. Using a screening approach, we characterised lipidomes of lung cancer tissues and corresponding tumour-free alveolar tissues. We quantified 311 lipids from 11 classes in 43 tissue samples from 26 patients...

We assessed the relationships between changes in lung compliance, lung volumes and dynamic hyperinflation in patients with emphysema who underwent bronchoscopic treatment with nitinol coils (coil treatment) (n=11) or received usual care (UC) (n=11). Compared with UC, coil treatment resulted in decreased dynamic lung compliance (CLdyn) (p=0.03) and increased endurance time (p=0.010). The change in CLdyn was associated with significant improvement in FEV1 and FVC, with reduction in residual volume and intrinsic positive end-expiratory pressure, and with increased inspiratory capacity at rest/and at exercise...

Endoscopic lung volume reduction has emerged over the past several years as a promising technique to improve the respiratory functional status of patients with advanced emphysema. Nevertheless, the procedure may be associated with various complications; among them, the development of bronchiectasis related to the coils has not yet been described. We report the case of a patient with emphysema who developed localized bronchiectasis at the site of coil insertion several months after lung volume reduction coil treatment...

Chronic obstructive pulmonary disease (COPD) is an incurable and progressive disease. Emphysema is the principal manifestation of COPD, and the main cause of this condition is cigarette smoke (CS). Natural products have shown antioxidant and anti-inflammatory properties that can prevent acute lung inflammation and emphysema, but there are few reports in the literature regarding therapeutic approaches to emphysema. We hypothesized that supplementation with natural extracts would repair lung damage in emphysema caused by CS exposure...

BACKGROUND: Pulmonary sequestration is a relatively rare condition in which a systemic artery supplies blood to an abnormal lung tissue and the normal connection with the bronchial tree is absent. It can be displayed as various signs on the computed tomography image, but emphysema is extremely rare. CASE PRESENTATION: We describe the case of a 35-year-old man with intralobar pulmonary sequestration that appeared as localized emphysema on the computed tomography image...

RATIONALE: Studies of excised lungs show that significant airway attrition in the 'quiet' zone occurs early in chronic obstructive pulmonary disease (COPD). OBJECTIVES: To determine if the total number of airways quantified in vivo using computed tomography (CT) reflects early airway-related disease changes and is associated with lung-function decline independent of emphysema in COPD. METHODS: Participants in the multi-centre, population-based, longitudinal CanCOLD study underwent inspiratory/expiratory CT at visit-1; spirometry was performed at four visits over 6-years...

REVIEW
Amy Hajari Case, Peace Johnson
Idiopathic pulmonary fibrosis (IPF) is a rare lung disease characterised by progressive loss of lung function, dyspnoea and cough. IPF has a variable clinical course but a poor prognosis. Nintedanib, a tyrosine kinase inhibitor, is one of two drugs approved for the treatment of IPF. In clinical trials, nintedanib slowed disease progression by reducing the rate of decline in forced vital capacity (FVC) in patients with IPF and mild or moderate lung function impairment. The effect of nintedanib was consistent across patient subgroups defined by baseline characteristics including FVC % predicted, diffusion capacity of the lung for carbon monoxide % predicted and the presence of emphysema...

Primary or isolated pulmonary interstitial glycogenosis (PIG) is a rare disease presenting as tachypnea and hypoxemia during the perinatal period. A diffuse interstitial infiltrate with focal hyperinflation is visible on chest imaging. The biopsy findings include diffuse expansion of the interstitium by spindle-shaped cells with pale cytoplasm that, on electron microscopy (EM), are poorly differentiated mesenchymal cells containing abundant monoparticulate glycogen. This glycogenosis appears to be a transient abnormality, usually with a favorable prognosis...

Chronic obstructive pulmonary disease (COPD) is characterized by persistent airflow limitation and lung parenchymal destruction. It has a very high incidence in aging populations. The current conventional therapies for COPD focus mainly on symptom-modifying drugs; thus, the development of new therapies is urgently needed. Qualified animal models of COPD could help to characterize the underlying mechanisms and can be used for new drug screening. Current COPD models, such as lipopolysaccharide (LPS) or the porcine pancreatic elastase (PPE)-induced emphysema model, generate COPD-like lesions in the lungs and airways but do not otherwise resemble the pathogenesis of human COPD...
