A five month-old infant with congenital lobar emphysema is presented. Due to previously suspected diaphragmal hernia the infant underwent the surgery. Clinically, disorder was manifested with mild to severe respiratory symptoms. The indication for surgery was based on the radiological finding (hyperinflation of right upper lobe , as well as the computed tomography (herniation of the right lung to the left), lung scintigraphy (impaired perfusion of the right lung), bronchoscopy and bronchography the surgery, respectively. After lobectomy of upper right lobe the diagnosis was confirmed histopathologically as well ...

The prevalence of chronic obstructive pulmonary disease (COPD) is high (13.4%). In addition, COPD ranked 10th among the causes of death in Korea, and rose to 7th in 2008. Airflow limitation of COPD is caused by a mixture of small airway disease (obstructive bronchiolitis) and parenchyma destruction (emphysema). Bronchodilator and anti-inflammatory drugs, such as corticosteroids are effective to obstructive bronchiolitis. However, these drugs are not effective to emphysema.. Lung volume reduction was devised to remove hyperinflated lung, and to function remaining lung. Surgical lung volume reduction showed improving survival in selected emphysema patients. However, surgical lung volume reduction have bee performed rarely due to significant surgery-related mortality. In this regard, non-surgical lung volume reduction methods have been developed. Of them, bronchoscopic lung volume reduction by endobronchial one-way valve is mostly used method and showed lower early complications than ...
Lung Volume Reduction Surgery for emphysema has evolved over the last two decades since the original description by Brantigan [11]. Cooper and colleagues popularised the use of stapled excision of the emphysematous lung with good outcomes [1]. This was followed by a number of groups pursuing varied selection criteria and techniques with mixed results [4, 12-14]. However, the selection criteria and benefits of LVRS in end stage emphysema has been established in the National Emphysema Treatment Trial [2] with durable long term results in select group of patients [15].. One of the major complications of stapled LVRS is prolonged air leak which occurs in 50-90% of the patients [3]. A number of adjuncts to prevent air leak have been advocated which include bovine pericardium, Gore-Tex or autologous pleura [3, 6]. The buttressing of the staple line has been shown to reduce the duration of air leak and time to chest drain removal [6]. In our centre, the standard approach to Lung Volume Reduction ...
Lobar Emphysema 1 (Differential Diagnosis RDS). Repeated chest radiographs in a newborn with progressive respiratory distress syndrome. Left picture: 3rd day of life. The upper right hemithorax is larger than its left counterpart. Notice the large intervals between the ribs. Center picture: 10th day of life. The difference between left and right becomes more pronounced; an absent lung structure in the right upper and middle hemithorax is recognizable. Right picture: 21st day of life: There is no heart shadow in the right hemithorax; an increase of the zone with absent lung structure is obvious and partially so in the left hemithorax, too. In contrast to the sudden onset of respiratory distress syndrome in most patients with congenital diaphragmatic hernia, respiratory distress syndrome or the signs of the respiratory system appear slowly during the neonatal period in many of the pathologies with a valve mechanism. In this case the pathology is a lobar emphysema of the right upper lobe. The lobe ...
National Trial Yields First Scientific Evidence of Who Should Have Surgery-. New York, NY (Aug. 14, 2001) - The National Emphysema Treatment Trial (NETT), in which Columbia Presbyterian Medical Center of NewYork-Presbyterian Hospital is a major participant, has found that certain advanced emphysema patients benefit little from Lung Volume Reduction Surgery (LVRS) and are at unacceptable risk of death from the procedure. The NETT trial - a five-year, multicenter, randomized study designed to evaluate the role of LVRS in the treatment of severe emphysema - indicates that those patients who have severe lung obstruction with either limited ability to exchange gas while breathing or damage that is evenly distributed throughout their lungs should not undergo LVRS ...
Previous studies have suggested a role for an increased apoptosis of the endothelial cells in the pulmonary capillaries of the alveolar septa in the pathogenesis of human pulmonary emphysema.1 In animal models, circulating endothelial stem cells, characterised by the concomitant expression of CD34+, CD133 and vascular endothelial growth factor receptor 2 (VEGF-R2), may contribute to the repair of lung damage.2 However, it is unknown if a decrease in the blood of these stem cells contributes to the pathogenesis of pulmonary emphysema in humans. The aim of our study was to investigate by flow cytometry the number of total (CD34+) and endothelial stem (triple positive for CD34+/CD133/VEGF-R2) cells in the peripheral venous blood of current and former smokers of similar age, with or without pulmonary emphysema.. All the recruited subjects were free from concomitant diseases or drugs able to interfere with the number of circulating stem cells. Venous blood samples were obtained from 37 subjects (mean ...
Pulmonary emphysema is receiving increasing recognition as one of the countrys major health problems. The prevalence of bronchitis and pulmonary emphysema has been estimated as 13 per thousand, meaning that over 2,000,000 people in this country have these diseases. Unfortunately, many American physicians are not sufficiently aware of this problem nor do they understand the pathophysiology of this disease. A book such as Dr. Rosenman has attempted, designed to present in clear and simple terms the essence of pulmonary physiology and describe the abnormal physiology and treatment of pulmonary emphysema, could be a valuable aid to the medical student and ...
There are several potential issues that affect the treatment and diagnostic pattern of anomalous left coronary artery arising from the pulmonary artery. We report three cases of infants who presented with anomalous left coronary artery arising from the pulmonary artery with severe left ventricular dysfunction and severe mitral regurgitation along with associated anomalies. One patient had congenital lobar emphysema of the right midde lobe. Another patient had left main stem bronchus compression, collapse of basal segments of left lower lobe and panlobular emphysema in medial basal segment of right lower lobe. The third patient had cleft lip and palate. All patients underwent successful repair. The hemodynamic stability was compromised when the infant with congenital lobar emphysema had spontaneous pneumothorax after extubation and she needed an intercostal drainage. The infant with lung collapse had to be reintubated on the second day since she became hypoxic due to recollapse of the lung once the

Emphysema is a progressive, debilitating disease that affects nearly 3 million people in the United States or roughly one percent of the US population. The disease is characterized by destruction of lung tissue as a result of inflammation caused by exposure to noxious inhaled agents for extended periods. The most common cause of this condition is cigarette smoking, although genetic and occupational causes account for up to 10% of cases. Despite aggressive public health initiatives aimed at discouraging the use of cigarettes, smoking-related lung diseases remain a significant cause of disability and death in the United States. Currently there are 46 million smokers in the US. Due to the number of current and new smokers, emphysema is expected to remain a leading cause of morbidity and mortality in the United States for years to come.. Aeris has developed a novel bronchoscopic system for achieving the benefits of lung volume reduction without surgery. The Bronchoscopic Lung Volume Reduction (BLVR) ...

This book, edited by two outstanding students of the clinical aspects of pulmonary emphysema, actually consists of a series of essays pertaining to various aspects of the syndrome.. The first half of the book (which, in the reviewers opinion, should be the second half) consists of a series of comprehensive and detailed discussions of the clinical management of pulmonary emphysema, as practiced by Dr. Barach and his group. There is no doubt that most of their beliefs are sound and based on long experience. However, one concept may need questioning. They strongly advocate using oxygen therapy for the hypoxic episodes ...
Pulmonary emphysema. Frontal computed tomography (CT) scan of a male patients chest showing severe emphysema in the left lung (right). There is a large area of trapped air (black) in the affected lung. Emphysema causes the tiny air sacs of the lungs to become damaged, leading to the walls between them breaking down. This causes large areas of trapped air and leads to a smaller surface area for gaseous exchange, restricting oxygen uptake by the blood. Enlarged air spaces bigger than 1 centimetre in diameter are known as bullae. Lung tissue in bullae may be completely destroyed. The main cause of emphysema is cigarette smoking. Symptoms include a cough and shortness of breath. Bullae may be surgically removed although there is no cure for emphysema. - Stock Image C021/2971

Measurements of lung parenchyma, membranous bronchioles, and bronchial mucous gland hyperplasia were made on lungs from eight cases of pure centrilobular emphysema (CLE) and on five normal lungs. The lungs were fixed in formalin and inflated under partial vacuum at a standard transpulmonary pressure of +30 cm. H2O. The results obtained from the upper halves and the lower halves of the lungs were compared. The circulatory effects of the disease were measured by weighing the heart ventricles, by studying the small pulmonary arteries in microscopical sections, and by post-mortem arteriography. Whereas the parenchymal and internal surface areas destroyed by the emphysematous spaces were relatively moderate and localized, right ventricular hypertrophy was noted in most of the cases. In these cases bronchiolar stenoses were found scattered throughout the whole lung and there was a reduction in the number of these bronchioles, mainly in the upper halves of the lungs. In CLE ventilatory disturbances ...

abstract = "Study objectives: In 1996, researchers in Sweden initiated a collaborative randomized study comparing lung volume reduction surgery (LVRS) and physical training with physical training alone. The primary end point was health status; secondary end points included survival and physiologic measurements. Design: After an initial 6-week physical training program, researchers patients were randomized to either LVRS (surgical group [SG]) with continued training for 3 months, or to continued training alone (training group [TG]) for 1 year. Setting: All seven thoracic surgery centers in Sweden. Patients: All patients in Sweden with severe emphysema fulfilling inclusion criteria for LVRS. Interventions: Patients randomized to surgery underwent a median sternotomy, except for a few patients in whom thoracotomy or video-assisted thoracoscopy were performed. In the TG, supervised physical training continued for 1 year; in the SG, supervised physical training continued for 3 months ...
Lung Volume Reduction Surgery (LVRS) is a surgical procedure in which sections of severely damaged lung tissue are removed. By removing the most diseased tissue (up to 30% of the lung volume), the goal is to improve the residual lung function and respiratory mechanics in patients with end-stage emphysema. LVRS can be performed through either median sternotomy (open chest) or video-assisted minimally invasive technique. Studies show LVRS significantly improves quality of life, increases exercise capacity and even improves survival in carefully selected patients.

p,X-ray computed tomography (CT) has been used for diagnosis of pulmonary emphysema because it can reveal the morphology of low attenuation areas. Recently, 99mTc-Technegas imaging, one of several types of scintigraphic techniques, has been used for ventilation scintigraphy. Technegas scintigraphy was performed on 15 patients with pulmonary emphysema, and we compared the extent and degree of abnormal findings on Technegas scintigraphy with the extent of low attenuation areas shown by CT. We classified the findings of Technegas imaging into three grades, from mild to severe, according to the extent of peripheral irregularity and central hot spot formation. We also classified the findings of CT as centrilobular emphysema into three grades from mild to severe according to the extent of low attention areas in the peripheral lung fields. In 5 cases, CT and Technegas assessment resulted in equivalent diagnoses. In eight cases, Technegas images showed more detailed findings than CT images. In the two ...
The reintroduction in the mid-1990s of the surgical method originally conceived by Brantigan et al. [1], lung volume reduction, showed that under certain circumstances this treatment could improve the forced expiratory volume in one second (FEV1), indices of resting hyperinflation and quality of life [2].. However, three factors taken together have meant that lung volume reduction surgery (LVRS) has been useful in only a minority of patients. A significant proportion of patients, between one-quarter and one-third, fail to derive significant benefit from the procedure. This in itself might not matter if it were not for the second problem, which is that in large series, the mortality rate has been ≥4-5% [2-4]. While this risk might be acceptable if success were guaranteed, it is less appealing if it is not. Finally, in order to reduce mortality and morbidity, most groups impose safety criteria so that patients who are too disabled are not eligible for LVRS. Thus, in the present authors centre, ...
A characteristic "barrel chest" is often seen in pulmonary emphysema. The appearance of the barrel chest is the result of lungs chronically overinflated with air causing the rib cage to stay partially expanded.. Two identifiers common in COPD are "blue bloater" and "pink puffer." A blue bloater describes a person with chronic bronchitis whose body responds to the increased obstruction by decreasing ventilation and increasing cardiac output. This leads to hypoxemia (oxygen deficiency in the blood) and polycythemia (excessive red blood cells). Together with retention of carbon dioxide, individuals show signs of cardiac failure and are described as blue bloaters.. A pink puffer describes a person with emphysema who has the decreased inability to oxygenate the blood. The body compensates with lower cardiac output and hyperventilation, causing a reddish complexion and a "puffing" appearance when breathing.. Diagnostic Procedures. A physical examination, chest x-ray, pulmonary function tests, arterial ...

Emphysema is largely an under-diagnosed medical condition that can exist in smokers in the absence of airway obstruction. We aimed to determine the sensitivity and specificity of pulmonary function tests (PFTs) in assessing emphysema using quantitative CT scans as the reference standard. We enrolled 224 ever-smokers (current or former) over the age of 40. CT of thorax was used to quantify the low attenuation area (% emphysema), and to measure the standardized airway wall thickness. PFTs were used individually and in combination to predict their ability to discriminate radiographic emphysema. Significant emphysema (|7%) was detected in 122 (54%) subjects. Twenty six (21%) emphysema subjects had no evidence of airflow obstruction (FEV1/FVC ratio 23% emphysema showed airflow obstruction. The sensitivity and specificity of spirometry for detecting radiographic emphysema were 79% and 75%, respectively. Standardized airway wall thickness was increased in subjects with airflow obstruction, but did not

Working with coal, whether as a miner or in other ways, results in an accumulation of coal or other dust in macrophages in and around respiratory bronchioles. Mild dilatation of respiratory bronchioles results, probably from atrophy of muscle. The lesion resembles centrilobular emphysema but differs in that the enlarged spaces are smaller and more regular, and inflammation of bronchioles is not apparent. Thus, the lesion is primarily distensive rather than destructive. The anatomic lesion is usually equated with a chest radiograph that shows small nodular densities, although the complete correlation has not been proved. The condition, also referred to as black lung, has been considered to cause severe disability. Contemporary evidence, however, suggests that simple coal pneumoconiosis causes only minor impairment of pulmonary function. When coal miners have severe chronic airflow obstruction, it is usually due to other forms of emphysema, notably tobacco-related centrilobular emphysema. Other ...

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. Mice were exposed to 60days of CS and then treated or not with three different natural extracts (mate tea, grape and propolis) orally for additional 60days. Histological analysis revealed significant improvements in lung histoarchitecture, with recovery of alveolar spaces in all groups treated with natural extracts. Propolis was also able to recovery alveolar septa and elastic fibers. Propolis also increased MMP-2 and decreased MMP-12 expression, favoring the process of

The goal of this study was to identify gene expression changes associated with regional emphysema severity in order to elucidate biological processes underlying the progression of emphysema and to identify potential COPD therapeutics. By measuring gene expression from regions of varying emphysema severity within the same lung and by using a morphologic measurement of airspace size (Lm), which reflects the degree of alveolar destruction, we were able to identify gene expression changes associated specifically with the emphysematous component of COPD.. Interestingly, there was significant enrichment between genes differentially expressed in COPD or associated with worsening lung function in other datasets and those we found to be associated with regional emphysema severity. Importantly, this similarity supports the notion that regional differences in emphysema severity reflect the processes that occur with general COPD pathogenesis and progression and are not only present in patients with ...
