Fragile lung in the Marfan syndrome. (1/1021)

Two cases of the Marfan syndrome presented with spontaneous pneumothorax. Both had chest radiographs showing bilateral bullae in the upper lung zones and pulmonary function tests consistent with mild emphysema. There were dereases in forced expiratory flow rates at low lung volumes, carbon monoxide transfer factor, and lung elastic recoil. It is suggested that pneumothorax and bullous emphysema in this syndrome are caused by a weakness in the pulmonary connective tissue framework.  (+info)

Detection of anti-cytokeratin 8 antibody in the serum of patients with cryptogenic fibrosing alveolitis and pulmonary fibrosis associated with collagen vascular disorders. (2/1021)

BACKGROUND: It has been suggested that the humoral immune system plays a role in the pathogenesis of cryptogenic fibrosing alveolitis (CFA). Although circulating autoantibodies to lung protein(s) have been suggested, none of the lung proteins have been characterised. The purpose of this study was to determine the antigen to which the serum from patients with pulmonary fibrosis reacted. METHODS: The anti-A549 cell antibody was characterised in a patient with CFA using Western immunoblotting and immunohistochemical staining of A549 cells. As we identified that one of the antibodies against A549 cells was anti-cytokeratin 8, the expression of mRNA of cytokeratin 8 in A549 cells was evaluated. In addition, we attempted to establish an enzyme linked immunosorbent assay to measure the levels of anti-cytokeratin 8 antibody in the serum of patients with CFA and pulmonary fibrosis associated with collagen vascular disorders (PF-CVD). RESULTS: Initially two anti-A549 cell antibodies were detected in the serum of patients with pulmonary fibrosis, one of which was characterised as anticytokeratin 8 antibody by Western immunoblotting. We were able to establish an ELISA to measure anti-cytokeratin 8 antibody and found significantly higher levels in patients with CFA and PF-CVD than in normal volunteers, patients with sarcoidosis, pneumonia, and pulmonary emphysema. CONCLUSIONS: One of the anti-A549 cell antibodies in the serum of patients with CFA was against cytokeratin 8. The serum levels of anti-cytokeratin 8 antibody were increased in patients with CFA and PF-CVD. These results suggest that anticytokeratin 8 antibody may be involved in the process of lung injury in pulmonary fibrosis.  (+info)

Improvements in thoracic movement following lung volume reduction surgery in patients with severe emphysema. (3/1021)

In twelve patients with severe emphysema who underwent lung volume reduction surgery (LVRS), we assessed the results of dyspnea scale, pulmonary function, 6-minute walk distance (6MD), and thoracic movement prior to and 6 months following LVRS. Postoperatively, forced expiratory volume (FEV1), maximum inspiratory mouth pressures (MIP), maximum expiratory mouth pressures (MEP), maximum voluntary ventilation (MVV), diffusing capacity for carbon monoxide (DLCO), partial pressure of oxygen (PaO2) and 6MD were significantly increased with the decrease in dyspnea scale and lung hyperinflation. Thoracic movement, as assessed by the bilateral lung area ratio of the mid-sagittal dimension of dynamic magnetic resonance imaging (MRI) at full inspiration to that at full expiration, was significantly increased. The improvement in thoracic movement was significantly correlated with the increases in FEV1, MVV, and MIP, and with the decrease in residual volume (RV), and with the improvement in the dyspnea scale. These findings suggest that LVRS is an effective procedure for improving not only the airflow limitation and gas exchange but also the thoracic movement in severe emphysema, and these improvements may contribute to an increase in exercise performance and relief of dyspnea.  (+info)

Physiological basis of improvement after lung volume reduction surgery for severe emphysema: where are we? (4/1021)

Lung volume reduction surgery has become an accepted therapeutic option to relieve the symptoms of selected patients with severe emphysema. In a majority of these patients, it causes objective as well as subjective functional improvement. A proper understanding of the physiological determinants underlying these beneficial effects appears very important in order to better select patients for the procedure that is currently largely carried out on an empirical basis. Lung volume reduction surgery has two distinct effects. Firstly, it causes an increased elastic recoil, which at least partially explains the enhanced maximal expiratory flow. Secondly, it is associated with a reduction of hyperinflation which allows for an increase in global inspiratory muscle strength and in diaphragmatic contribution to tidal volume as well as a decrease in the inspiratory elastic load imposed by the chest wall. Taken together, these effects result in a reduced work of breathing and in an enhanced maximal ventilation which both contribute to the increased exercise capacity and reduced dyspnoea after surgery. The improved lung recoil and the reduced hyperinflation after volume reduction surgery were the primary postulates upon which the usual selection criteria for the procedure were based. It is now likely that these are correct. Nevertheless, some patients do not benefit from lung volume reduction surgery and the current literature does not allow for a refinement of the selection process from a physiological point of view. The exact mechanisms underlying the improvement in lung recoil, lung mechanics, and respiratory muscle function remain incompletely understood. Moreover, the effects of lung volume reduction surgery on gas exchange and pulmonary haemodynamics still need to be more fully investigated. An analysis of the characteristics of patients who do not benefit from the procedure and the development of an animal model for lung volume reduction surgery would probably help address these important issues.  (+info)

Subjective differentiation of normal and pathological bronchi on thin-section CT: impact of observer training. (5/1021)

The effect of observer training on sensitivity, specificity and interobserver agreement in the differentiation between normal and pathological bronchi on computed tomography (CT) was studied. The wall thickness of bronchi with normal walls and with pathologically thickened walls were subjectively scored by three independent observers before and after a training period of 2 weeks. Sensitivity, specificity and interobserver agreement were calculated for reading sessions before and after training. Increase and decrease in agreement after training were determined. There was a statistically significant difference (p=0.001) between objectively measured wall thickness of normal and pathological bronchi, both for reference bronchi and for bronchi used for reading sessions. While training increased interobserver agreement, it had no effect on sensitivity (0.46 versus 0.44 after training) and specificity (0.71 versus 0.72 after training) in detecting pathological bronchi. Increased agreement after training was significantly (p=0.001) more frequent than decreased agreement. There is a discrepancy between the effect of training on interobserver agreement and on sensitivity and specificity in the subjective differentiation between normal and pathological bronchi. Interobserver agreement alone is not a reliable indicator of a beneficial effect of training in the evaluation of this parameter.  (+info)

Outcome of asthma: longitudinal changes in lung function. (6/1021)

Current knowledge about factors determining outcome of asthma is limited, but observations over the last few decades suggest that active asthma has a negative impact on the longitudinal changes in lung function. This review aims to give an overview of the present knowledge concerning longitudinal changes in lung function, including clinical markers for distinctly poor outcome with regard to lung function, in children and adults suffering from asthma. The majority of patients with asthma have a good prognosis. However, some patients with asthma, especially those with more severe disease, are at risk of impaired growth of lung function during childhood, a lower maximally attained level of lung function and excessive decline in lung function in adulthood, which may lead to life-threatening lung function impairment. Clinical markers of poorly controlled airway inflammation appear to have a negative impact on the longitudinal changes in lung function, and disease progression to nonreversible airflow obstruction may be observed in a minority of patients with asthma. Early intervention with anti-inflammatory therapy may improve the short-term outcome of asthma, but long-term controlled studies are clearly needed in order to verify whether or not treatment, especially with inhaled corticosteroids, according to the current international guidelines alters the natural history of asthma, i.e. disease progression with regard to changes in lung function and possible development of nonreversible airflow obstruction.  (+info)

Surgical aspects and techniques of lung volume reduction surgery for severe emphysema. (7/1021)

Lung volume reduction surgery (LVRS) has become an accepted procedure for palliative treatment of diffuse, nonbullous emphysema. Single or multiple peripheral segmental wedge resections of the most destroyed areas of the lungs are performed with the use of stapling devices, in order to decrease hyperinflation and restore diaphragmatic function. Median sternotomy, videoendoscopy or anterior muscle sparing thoracotomies have been used as surgical approaches. The functional improvement after bilateral resections exceed those after a unilateral approach. LVRS has demonstrated its potential as an alternative to transplantation, and with growing experience, the indications for the procedure have been widened. In selected patients with peripheral lung cancer who have been considered unsuitable for a surgical resection, the combination of both tumour resection and LVRS has successfully been performed. In contrast to LVRS, laser surgery of the emphysematous lung has been abandoned in most institutions.  (+info)

Emphysematous lesions, inflammation, and fibrosis in the lungs of transgenic mice overexpressing platelet-derived growth factor. (8/1021)

Because of its expression pattern and its potent effects on mesenchymal cells, platelet-derived growth factor (PDGF) has been implicated as an important factor in epithelial-mesenchymal cell interactions during normal lung development and in the pathogenesis of fibrotic lung disease. To further explore the role of PDGF in these processes, we have developed transgenic mice that express the PDGF-B gene from the lung-specific surfactant protein C (SPC) promoter. Adult SPC-PDGFB transgenic mice exhibited lung pathology characterized by enlarged airspaces, inflammation, and fibrosis. Emphysematous changes frequently occurred throughout the lung, but inflammation and fibrotic lesions were usually confined to focal areas. The severity of this phenotype varied significantly among individual mice within the same SPC-PDGFB transgenic lineage. A pathology similar to that observed in adult mice was noted in lungs from transgenic mice as young as 1 week of age. Neonatal transgenic mice exhibited enlarged saccules and thickened primary septa. Results of these studies indicated that overexpression of PDGF-B induced distinct abnormalities in the developing and adult lung and led to a complex phenotype that encompassed aspects of both emphysema and fibrotic lung disease.  (+info)

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.

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
Several studies report that high-density lipoproteins (HDLs) can carry α1-antitrypsin (AAT; an elastase inhibitor). We aimed to determine whether injection of exogenous HDL, enriched or not in AAT, may have protective effects against pulmonary emphysema. After tracheal instillation of saline or elastase, mice were randomly treated intravenously with saline, human plasma HDL (75 mg apolipoprotein A1/kg), HDL-AAT (75 mg apolipoprotein A1-3.75 mg AAT/kg), or AAT alone (3.75 mg/kg) at 2, 24, 48, and 72 hours. We have shown that HDL-AAT reached the lung and prevented the development of pulmonary emphysema by 59.3% at 3 weeks (alveoli mean chord length, 22.9 ± 2.8 μm versus 30.7 ± 4.5 μm; P , 0.001), whereas injection of HDL or AAT alone only showed a moderate, nonsignificant protective effect (28.2 ± 4.2 μm versus 30.7 ± 5 μm [P = 0.23] and 27.3 ± 5.66 μm versus 30.71 ± 4.96 μm [P = 0.18], respectively). Indeed, protection by HDL-AAT was significantly higher than that observed with HDL ...
If surgery is necessary in the neonatal period, respiratory failure is likely a key feature of the infants condition. Intubation in the nursery is likely with concomitant insertion of an umbilical arterial line. Following transport to a warmed, operating room and application of usual monitors, the infant should be placed on a forced warm-air device and covered with plastic where possible to maintain body temperature. Overhead warming lights should be used to maintain temperature as the baby is prepared for surgery. Two avenues of venous access should be obtained to permit glucose administration in independent of fluid and medication administration. An umbilical venous catheter could be used as one intravenous system. A fluid-warming system should be charged so that blood can be immediately administered..

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..

Localized emphysema is difficult to detect on normal thoracoscopy. Indocyanine green (ICG) was used to precisely delineate an emphysematous lesion using an infrared camera system in a 75-year-old woman with a large emphysematous lesion in the right lower lobe. Due to repeated infections of the emphysematous lesion, right basal segmentectomy for localized lung emphysema was performed. During surgery, ICG (0.5 mg/kg) was injected intravenously, and the emphysematous lesion was detected as a fluorescence defect. This method could be used for precise resection of large emphysematous lesions because it permits clear detection with a small amount of ICG.
Pulmonary emphysema is primarily the end-stage of lung diseases such as chronic bronchitis or COPD. Read more about symptoms, causes, and treatment.. Synonyms. Emphysema pulmonum, pulmonary emphysema, pulmonary hyperinflation, pulmonary distension. Definition. Pulmonary emphysema is a serious, progressive, and incurable disease of the lungs. Medical professionals also refer to it as pulmonary emphysema. The colloquial language is particularly familiar with the disease terms lung flatulence or lung overinflation. With pulmonary emphysema, lung function continues to decrease. This creates progressive shortness of breath. The associated lack of oxygen not only severely restricts physical performance. There are also secondary reactions that place a heavy strain on the heart, among other things. A typical consequence of emphysema is, for example, the cor pulmonale, a common form of right heart failure.. Alpha-1 Antitrypsin Deficiency. In addition to the acquired form of emphysema, there is also a ...
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

Abstract: Bronchogenic cysts are rare congenital lesions of the bronchial tree which are mostly asymptomatic. Rarely when the size is large it can compress on the adjacent structures in the mediastinum. We report a rare case of 10 month old baby presented with recurrent lower respiratory tract infection, was suspected to have a pericardial cyst on echocardiography. On further imaging it was confirmed to be a large bronchogenic cyst from the carina compressing on the left atrium and the left bronchus causing congenital lobar emphysema of the left lung. In view of compression of the adjacent structures patient was sent for surgery. Though congenital bronchogenic cysts involving pericardium and intracardiac tissues have been reported but mediastinal bronchogenic cysts compressing on left bronchus causing congenital lobar emphysema have rarely been reported. Key words: Bronchogenic cyst, Congenital lobar emphysema.. ...

AU - Miyamoto, K.. AU - Kawakami, Y.. PY - 1996/12/1. Y1 - 1996/12/1. N2 - We examined the relationship between neutrophil elastase, elatin- derived peptides in bronchoalveolar lavage (BAL) fluid, and the development of pulmonary emphysema. The level of neutrophil elastase was higher in asymptomatic current smokers with emphysematous changes on computed tomographic scans than in current smokers without emphysematous changes, and was found to be correlated with the level of elastin-derived peptides in BAL fluid. Subjects with high levels of neutrophil elastase in BAL fluid had faster annual declines in FEV1. We conclude that the level of neutrophil elastase in BAL fluid can be used to differentiate asymptomatic cigarette smokers who are at risk for pulmonary emphysema from those who are not.. AB - We ...

Beiko T, Janech MG, Alekseyenko AV, et al; for the QUANTUM-1 Investigators. Serum proteins associated with emphysema progression in severe alpha-1 antitrypsin deficiency.
In the largest study of its kind, to date, we have shown that elevated pDES levels relate to cardiovascular comorbidities, aortic stiffness, and mortality in patients with COPD, but not to emphysema, emphysema progression, as assessed by CT scans, or FEV1 decline. The association with coronary artery disease was particularly significant in patients with persistently elevated levels of pDES. We also confirmed that patients with COPD had higher pDES compared with age- and sex-matched controls.. These observations suggest that pDES is predominantly a reflection of elastin degradation in vascular tissue, potentially caused by aberrant inflammation in vascular tissues, contributing to worse cardiovascular outcomes and mortality. This notion is supported by results in a second independent cohort where pDES was related to cardiovascular comorbidities and aortic PWV as a measure of arterial stiffness, suggesting that increased arterial stiffness may also result from systemic elastin degradation in the ...
Researchers at the University of Alabama at Birmingham injected a foam sealant into the lungs of a former smoker on Oct. 29, 2012, to treat his worsening emphysema. He was the first patient in the United States treated in a late-stage clinical trial of the AeriSeal System. The therapy, approved for use in parts of Europe and Israel, is undergoing investigation in the U.S. as a potential method of reducing lung volume in patients with severe emphysema.. Emphysema, a lung disease usually caused by smoking, damages air sacs in the lung called alveoli. The sacs fill with air that the body is unable to exhale, causing the lungs to expand. This in turn flattens the diaphragm, the primary muscle used for breathing. The flattened diaphragm is unable to function properly, making it extremely difficult for the individual to breathe. An estimated 4.9 million Americans have been diagnosed with emphysema.. A treatment known as lung volume reduction surgery has been employed to treat emphysema with some ...

COPD is a term that refers to a large group of lung diseases that can interfere with normal breathing. According to the American Lung Association, more than 12 million Americans have COPD, and an additional 12 million may have impaired lung function, suggesting it may be significantly underreported. As many as 24 million people may be affected. The two most common conditions of COPD are chronic bronchitis and emphysema.. The causes of COPD are not fully understood. It is generally agreed that the most important cause of chronic bronchitis and emphysema is cigarette smoking. Causes such as air pollution and occupational exposures may play a role, especially when combined with cigarette smoking. Heredity also plays a contributing role in some patients emphysema, and is especially important in a rare form due to alpha 1 anti-trypsin deficiency.. Patients with chronic bronchitis usually have a cough and sputum production for many years before they develop shortness of breath.. Patients with ...
Berlin, Germany - Germanys Institute for Quality and Efficiency in Healthcare (IQWiG) recently published a commissioned study that assessed the available surgical and bronchoscopic lung volume reduction options for patients with severe pulmonary emphysema. Uptake Medicals recent randomized controlled trial (STEP-UP) of its Bronchoscopic Thermal Vapor Ablation (BTVA) InterVapor therapy was included in the German analysis.. The report included an analysis of patient relevant safety outcomes for each method analyzed. Of the bronchoscopic methods actively being used in Germany (vapor, EBV valves, IBV valves, and coils) vapor has the strongest safety profile. The comparison in Table 13 of the report concludes that coils and valves have evidence [or] indication of harm to the treatment group as compared to the control group in the category of other adverse effects and complications of therapy. This is related to the high rates pneumothorax, hemoptysis, and other complications following ...

α1-antitrypsin deficiency (AATD) is the most common hereditary disorder in adults. It is associated with an increased risk of developing pulmonary emphysema and liver disease. The pulmonary emphysema in AATD is strongly linked to smoking, but even a proportion of never-smokers develop progressive lung disease. A large proportion of individuals affected remain undiagnosed and therefore without access to appropriate care and treatment.The most recent international statement on AATD was published by the American Thoracic Society and the European Respiratory Society in 2003. Since then there has been a continuous development of novel, more accurate and less expensive genetic diagnostic methods. Furthermore, new outcome parameters have been developed and validated for use in clinical trials and a new series of observational and randomised clinical trials have provided more evidence concerning the efficacy and safety of augmentation therapy, the only specific treatment available for the pulmonary ...
RADIOLOGY: HEPATOBILIARY: Case# 3: EMPHYSEMATOUS CHANGE SECONDARY TO ALPHA I ANTITRYPSIN DEFICIENCY, CIRRHOSIS. 61 year old man referred with hepatocellular carcinoma to rule out metastasis. Bilateral lower-zone predominant emphysema is present. No pulmonary or pleural metastases. A low attenuation lesion is identified in the right posterior segement of the liver. The liver is small with a nodular contour. Alfa 1-Antitrypsin (A1-AT) is a secretory glycoprotien produced by the hepatocytes. Patients with homozygous ZZ or SS phenotype develop A1-AT deficiency which leads to early onset panacinar emphysema predominantly affecting the lower lobes as shown above. Associated bronchiectasis may also be seen. These patients also develop cirrhosis and leucocytoclastic vasculitis. Concomitant smoking and or environmental exposure hastens development of emphysema. Treatment includes intravenous substitution of A1-AT. - 00134409.jpg

A 26-week-gestation infant developed cystic lung changes which required lobar resection at 6 weeks of age. Lung histology showed cytomegalovirus (CMV) inclusion bodies. The authors present the radiology and histology images of this case and review the literature regarding congenital CMV infection and cystic lung disease. Lung disease caused by CMV is typically a diffuse pneumonitis. This is the first reported case of congenital CMV infection causing emphysematous lung disease to develop in the neonatal period. The case raises awareness of CMV as a possible cause of cystic lung lesions in newborns. ...
DESCRIPTION (provided by applicant): Pulmonary emphysema is a prevalent lung disease defined by permanent enlargement of airspaces, but also associated with systemic effects on organs that include the bone marrow and the cardiovascular system. Little is known about the mechanisms of systemic illness in emphysema and their impact, if any, on the lung disease. The lung destruction, clinically apparent after years of cigarette smoking has been attributed to protease-antiprotease imbalance, chronic inflammation, oxidative stress, and excessive alveolar cell death with loss of pulmonary capillaries that support the alveolar unit. We demonstrated that pluripotent cells contained in adipose stroma, called adipose stem or stromal cells promote capillary growth and limit ischemic tissue damage in models of acute skeletal muscle, myocardial, and cerebral ischemia and these salutary effects are mediated by angiogenic and anti-apoptotic paracrine factors. Given the feasibility of obtaining these stem cells, ...
The history holds the fundamental role in differentiating among asthma, chronic bronchitis, and emphysema. A private or family history of atopy, a history of seasonal worsening of disorder in response to some known environmental agent, perhaps seasonal, and marked variability in the severity of airflow obstruction, frequently with dramatic responsiveness to bronchodilator drugs, strongly support the identification of asthma. Exacerbation of wheezing by exposure to cold air or following the ingestion of a drug, and asthma variants, such as nocturnal cough sensitive to bronchodilator agents or exercise-induced asthma support the diagnosis of asthma. Cigarette smoking is a typical background factor in both chronic bronchitis and emphysema, and both diseases are infrequently found in the lack of this history. As new information collects on the pathogenesis, prevention, and treatment of emphysema, chronic bronchitis, and asthma, accurate identification is not unlikely to get increased value ...
Although many questions about emphysema remain unanswered, one thing is clear - quitting smoking can prevent the occurrence of emphysema and slow the disease. Other changes to your environment, such as avoiding smog, may also help prevent the development of emphysema or keep it from getting worse. Researchers continue to investigate the causes of and treatments for this disease.Things to consider include:

Air reaches the lungs through a series of ever-smaller tubes. First air passes through the trachea (TRAY-kee-a), which is the large windpipe from the throat down the neck. Then the trachea branches into smaller tubes called the bronchi (BRONG-ky), then into even smaller bronchi called bronchioles (BRONG-kee-olz) that branch still further deep into the lungs. The bronchioles end in tiny air sacs called alveoli. It is in the alveoli that the transfer of oxygen into the bloodstream and of carbon dioxide out of the bloodstream occurs. In emphysema, the bronchi and bronchioles are inflamed and continually swollen and clogged. This causes the alveoli to swell. These fragile air sacs burst and merge together. This damage to the alveoli makes it more difficult for the transfer of oxygen and carbon dioxide to take place. People with emphysema have difficulty breathing. It is usually caused by cigarette smoking, or a severe form of bronchitis called chronic obstructive bronchitis. Very often, a ...
Cigarette smoking is the major cause of emphysema. Among other causes of emphysema are industrial pollutants, aerosol sprays, non-tobacco smoke.
If you recognize any of the symptoms of emphysema and you fit under any category of the possible risk factors, you should speak with your physician immediately. Your doctor will most likely perform a fairly simple test known as spirometry, which tests how well a person can breathe. The test generally consists of blowing into a mouth piece connected to a device that will measure your lung capacity.. The doctor can also listen to your lungs with a stethoscope, or use x-rays or computerized tomography (CT) scans to view the lungs. However, these tests dont always indicate the possible development of emphysema, even though it may be present. Typically, these tests, in conjunction with a spirometry are enough to be indicative of the development of emphysema during its early stages.. ...
The surgeons from UT Southwestern Medical Center have designed a new procedure to retain the nipples original color while undergoing breast reduction surgery in men. It prevents discoloration which is common in men who go for the removal of excess breast fat typically after a weight loss.. The complete findings of this procedure are enlisted in the research paper, now published in the journal Aesthetic Surgery Journal Open Forum.. This new process involves the removal of the lower side of the breast and then re-lifting it towards the face, creating the natural breast shape. The excessive fat from breast and skin is removed from the lower side only.. Also read- How To Protect Yourself From Coronavirus Infection in the Gym.

COPD is not curable. Medicines are often used to control symptoms or to reverse acute exacerbations. COPD in all forms typically progresses if the patient continues to smoke. Therefore, smoking cessation is one of the most important factors in slowing down the progression of COPD. The use of bronchodilators, nebulisers and corticosteroids has been shown to be effective. Patients with chronic disease and significant lung function impairment (FEV1 , 50%) may also benefit from the regular use of inhaled steroids. Oxygen therapy is the only current medical intervention that is proven to prolong the lives of patients with this disease process. Oxygen is only indicated in patients with severe hypoxia documented by a physician. Oxygen should be administered with caution to patients with COPD due to a risk of CO2 retention. Surgical management includes single or double lung transplant, and lung volume reduction surgery (LVRS), which is currently being evaluated in a large, national trial in the UK. Many ...

Chronic Obstructive Pulmonary Disease: A disease of chronic diffuse irreversible airflow obstruction. Subcategories of COPD include CHRONIC BRONCHITIS and PULMONARY EMPHYSEMA.
Pulmonary apical fibrosis is a rare complication of ankylosing spondylitis (AS). The essential characteristics of this lesion are its very slow progression and frequently asymptomatic nature. Herein, we are presenting a patient with AS who rapidly developed pulmonary apical fibrosis in a 3-year period despite decreased musculoskeletal pains. The 60-year-old male applied with complaints of progressively increasing cough in the recent two years, dyspnea, and fatigue. He had no chronic disease except AS. He had no continuous medication except nonsteroid anti-inflammatory drugs for 2-3 days monthly since his musculoskeletal pains decreased in the recent years. His physical examination revealed reduced breath sounds in the upper zones of the right lung. Chest X-ray revealed increased diffuse opacity in the upper zones of the right lung. Thoracic high-resolution computed tomography showed a consolidation accompanied with traction bronchiectases compatible with chronic fibrosis in the upper lobe of the right

Emphysema is defined by destruction of airways distal to the terminal bronchioloe.. Physiology of emphysema involves gradual destruction of alveolar septae and of the pulmonary capillary bed, leading to decreased ability to oxygenate blood. The body compensates with lowered cardiac output and hyperventilation. Thus, V/Q mismatch results in relatively limited blood flow through a fairly well oxygenated lung with normal blood gases and pressures in the lung, in contrast to the situation in bronchitis patients who are referred to as blue bloaters. Because of low cardiac output, however, the rest of the body suffers from tissue hypoxia and pulmonary cachexia. Eventually, these patients develop muscle wasting and weight loss and are identified as pink puffers.. (In bronchitis, the reverse situation is the case. The body compensates to mucus clogged airways and a relatively intact alveolar bed with a decrease in ventilation and an increase in cardiac output, which worsens baseline ...
What does pocket reduction surgery involve?. Before recommending treatment or performing any procedure, the dentist will perform thorough visual and x-ray examinations in order to assess the condition of the teeth, gums and underlying bone. Pocket reduction surgery may be performed under local or general anesthetic depending on the preferences of the patient.. The gums will be gently pulled back from the teeth and bacteria and calculus (tartar) will be eliminated. Scaling and root planing will generally be required to fully remove the ossification (tartar) from the surface of the tooth root. If the root is not completely smooth, a planing procedure will be performed to ensure that when the gums do heal, they will not reattach to rough or uneven surfaces.. The final part of the surgery is usually the administration of an antimicrobial liquid to eliminate any remaining bacteria and promote healing. The gum is then sutured with tiny stitches that are left in place for 5-10 days.. Though the gums ...
There is no cure for emphysema and the damage to the lung tissue cannot be reversed, but it is possible to prevent the condition from getting worse and to improve symptoms.. Initially, the treatment of emphysema should address the cause of the condition. For example, quitting smoking should be a priority if you smoke to prevent further damage to the lungs.. Additionally, there are medications that can help to reduce shortness of breath and allow you to carry out your daily activities as normal. Bronchodilator and steroid medications can be administered in an inhaler device so that the medication is directly specifically to the airways.

When I first heard that 24-year-old British singer-songwriter Amy Winehouse was hospitalized with early stage emphysema I said what? DrugMonkey, a drug-abuse research colleague, has a terrific post up now on the link between Winehouses crack cocaine use, possible genetic predisposition, and the emergence of early-onset emphysema.. While sad to see a very young person so afflicted, I tend to be fascinated scientifically by these odd medical cases involving natural products - often drugs of abuse.. Im also particularly impressed by Amy Winehouses tremendous vocal talents and songwriting abilities. Her jazz and soul vocal style has been described as reminiscent of legends like Sara Vaughn and I find it striking that her songs are considered pop music in 2008. But like many incredible musicians before her, Winehouse at 24 has more legal problems, drug abuse issues and violent, self-destructive behaviors than most people might accumulate in several dozen lives. I echo DrugMonkeys call to ...
My lab focuses on understanding the pathogenesis of Acute Lung Injury (ALI), a life threatening pulmonary inflammatory condition, which affects over a quarter of million patients in the U.S. with a mortality rate of approximately 40 percent. It is associated with pneumonia, sepsis, and trauma, leading to pulmonary insufficiency and eventually multisystem organ failure. So far, there are no effective therapy targeting the underlying molecular and cellular mechanisms. The two major pathogenic features of ALI involves disruption of pulmonary vascular endothelial barrier and acquisition of a proinflammatory phenotype. The long term goal of my research is to identify novel mechanistic targets and assess the preventive and therapeutic benefit of targeting them against evolving ALI. In our lab we use integration of in vitro and in vivo techniques to dissect the pathways that are critical to endothelial cell (EC) inflammation and permeability. We use multidisciplinary approaches ranging from ...
