A spread of the addiction of tobacco smoking is valued on near 1 billion of people in the world, that involves growing number of morbidity and mortality by the reason of smoke related diseases. Lung cancer and chronic obstructive pulmonary disease (COPD) are the most serious and incurable diseases which are leading to a permanent disability as well as to premature death. There are factors that naturally increase the vulnerability of an individual on the coincidence of above disorders, such as pathophysiological conditions, systemic inflammation, bronchitis, emphysema, respiratory obstructive disease and precise genetic predispositions for COPD and lung cancer...

OBJECTIVE: The National Institute for Occupation Safety and Health-administered Coal Workers' Health Surveillance Program (CWHSP) provides radiographic pneumoconiosis screening for US coal miners. Radiographs are classified by readers according to International Labour Office criteria. In addition to pneumoconiotic parenchymal and pleural lung abnormalities, readers document radiographic features of importance (other symbols). Other symbols are not meant to imply a diagnosis or interpretation but are relevant as they provide information beyond a pneumoconiosis classification for features related to dust exposure and other aetiologies...

INTRODUCTION: Clinical onset of chronic obstructive pulmonary disease (COPD) is the point at which the disease is first identifiable by physicians. It is a poorly defined stage which seems to include both mild spirometric and non-spirometric disease, and could be described as early grade COPD, for practical purposes. While dyspnoea; chronic bronchitis and CT imaging evidence of emphysema and airway disease may be present very early, the lone significance of dyspnoea, the most relevant symptom in COPD in identifying these individuals, has been scarcely assessed...

Patients with severe emphysema have a higher risk of developing lung cancer, and their surgical risk increases when emphysema is accompanied by a giant bulla. Here, we describe a patient who had an emphysematous giant bulla in the right upper lobe that was treated with an endobronchial valve placement. Subsequently, a cancerous lesion on the contralateral lung was successfully removed by lobectomy.

Early-onset pulmonary emphysema is uncommon and its pathogenesis is poorly defined. A 30-year-old man was admitted to our intensive care unit with severe respiratory failure. Besides smoking heavily since the 14 years of age, he had habitually inhaled organic solvents, such as toluene, in his adolescence. High-resolution computed tomography showed evident pulmonary emphysema throughout the lung fields. Based on the findings of right heart catheterization, he was diagnosed with an acute exacerbation of chronic obstructive pulmonary disease complicated with pulmonary hypertension...

Pulmonary emphysema is an important radiological finding in chronic obstructive pulmonary disease patients, but bacteriological differences in pneumonia patients according to the severity of emphysematous changes have not been reported. Therefore, we evaluated the bacteriological incidence in the bronchoalveolar lavage fluid (BALF) of pneumonia patients using cultivation and a culture-independent molecular method. Japanese patients with community-acquired pneumonia (83) and healthcare-associated pneumonia (94) between April 2010 and February 2014 were evaluated...

Smoking-related lung diseases are among the most preventable and incurable ailments in the world. Smokers are at increased risk of developing chronic obstructive pulmonary disease that can be further complicated by emphysema and lung cancer. A subset of former smokers shows persistent lung inflammation and progressive loss of lung function, indicating a role for activation of acquired immunity in smoking-induced lung diseases. In addition to the well-established noxious effects of volatile compounds in cigarette smoke, incomplete combustion of tobacco generates nano-sized carbon black (nCB) that accumulate in lung myeloid dendritic cells and macrophages...

Lung transplantation is a viable treatment option for patients with end-stage lung diseases such as interstitial pneumonia/pulmonary fibrosis, emphysema, pulmonary hypertension, and so on. Collecting available clinical, physiological, serological, and surgical information of both donor and recipient is vital when planning relevant postoperative managements. The goal of the managements is to keep the transplanted lung (s) functional while preventing/treating infection, rejection, and ischemiareperfusion lung injury...

Masahito Naito, Yukitoshi Satoh
The intraoperative and postoperative air leakages in lung surgery are caused by factors related to patients as well as the surgical technique employed. Prevention and management of air leakage caused by these varied factors are essential for thoracic surgeons. The factors related to patients, such as severe emphysema, smoking history, and insufficient lobulation, should be evaluated before surgery. Although time-consuming, careful and reliable surgical techniques are required. After the lung surgery, management of drain is essential for controlling air leakage...

Platelet-derived growth factor (PDGF)-A, which only signals through PDGF-receptor-alpha (PDGFRα) is required for secondary alveolar septal formation. Although PDGFRα distinguishes mesenchymal progenitor cells during the saccular stage, PDGFRα-expressing alveolar cells persist through adulthood. PDGF-A sustains proliferation, limits apoptosis, and maintains alpha-smooth muscle actin (αSMA) containing alveolar cells, which congregate at the alveolar entry ring at postnatal day (P)12. PDGFRα-expressing, αSMA-containing, alveolar cells re-distribute in the elongating septum, suggesting that they migrate to the alveolar entry rings where mechanical tension is higher...

Chronic obstructive pulmonary disease (COPD) is a leading cause of death in the United States, yet even at risk or diagnosed patients misunderstand COPD and its consequences for their quality of life and mortality. This study explored how patients conceptualize the causes, symptoms, consequences, treatment, and risk for developing COPD. The study consisted of six focus groups: 39 participants who were adults > 40 and current smoker or have COPD symptoms, family history, or exposures. Although many participants had some familiarity with the breathing, lung function, physical, emotional, and social consequences of COPD, confusion and misunderstanding prevailed...

REVIEW
David G Parr, Beatriz Lara
Alpha-1 antitrypsin (AAT) functions primarily to inhibit neutrophil elastase, and its deficiency predisposes individuals to the development of chronic obstructive pulmonary disease (COPD). The putative protective serum concentration is generally considered to be above a threshold of 11 μM/L, and therapeutic augmentation of AAT above this value is believed to retard the progression of emphysema. Several AAT preparations, all derived from human donor plasma, have been commercialized since approval by the US Food and Drug Administration (FDA) in 1987...

A novel approach of size-based emphysema clustering has been developed, and the size variation and collapse of holes in emphysema clusters are evaluated at inspiratory and expiratory computed tomography (CT). Thirty patients were visually evaluated for the size-based emphysema clustering technique and a total of 72 patients were evaluated for analyzing collapse of the emphysema hole in this study. A new approach for the size differentiation of emphysema holes was developed using the length scale, Gaussian low-pass filtering, and iteration approach...

BACKGROUND: Coarse particulate matter (PM10-2.5) is primarily mechanically generated and includes crustal material, brake and tire wear, and biological particles. PM10-2.5 is associated with pulmonary disease, which can lead to right ventricular (RV) dysfunction. Although RV characteristics have been associated with combustion-related pollutants, relationships with PM10-2.5 remain unknown. OBJECTIVES: To quantify cross-sectional associations between RV dysfunction and PM10-2...
