Bronchopulmonary dysplasia is a lung disease that the most common complication of prematurity and chronic in neonates treated with mechanical ventilation and/or oxygen therapy. Children bronchopulmonary are at risk cardiovascular complications, such as pulmonary arterial hypertension left ventricular hypertrophy. The presented case concerns premature infant born 24 weeks gestation severe compli...
Pulmonary function studies were carried out during pregnancy in 8 normal women, in 8 patients with valvular (either mitral or aortic) heart disease, and in 8 patients with chronic pulmonary disease (either emphysema or sarcoidosis). In healthy pregnant women, changes in lung volumes and maximal expiratory flow rates were not significant. Diffusing capacity tended to decrease associated with unc...
The patient was a 61-year-old female with massive rotator cuff tear who had no history of smoking, COPD, asthma, or other pulmonary diseases. Four hours following shoulder arthroscopy, the patient developed progressive dyspnea, which was diagnosed as pneumothorax with subcutaneous emphysema extending to the neck and face. Chest tube was inserted promptly. The patient was discharged with a good ...
BACKGROUND In this study we set out to investigate the clinically observed relationship between chronic obstructive pulmonary disease (COPD) and aortic aneurysms. We tested the hypothesis that an inherited deficiency of connective tissue might play a role in the combined development of pulmonary emphysema and vascular disease. METHODS We first determined the prevalence of chronic obstructive ...
The occurrence of pneumomediastinum and subcutaneous cervical emphysema as complications of childhood pneumonia is very unusual. They results most often from respiratory manoeuvres that produce high intrathoracic pressure. Although they are largely benign, pneumomediastinum can cause compression of major blood vessels in the mediastinum resulting in life threatening complications. Therefore, ad...
The objectives of the present study were to reappraise chest radiography for the diagnosis of emphysema, using computed tomography (CT) as the reference standard, and to establish whether or not chest radiography is useful for phenotyping chronic obstructive pulmonary disease (COPD). Patients (n = 154) who had undergone posteroanterior and lateral chest radiography and CT for diagnostic purpose...
The coronary blood flow was determined in 9 individuals with pulmonary emphysema alone and emphysema with cor pulmonale. Intracardiac pressures, cardiac output and pulmonary functions were also studied. In S of the 9 cases coronary blood flow was within the normal range. In one case with a high cardiac output the coronary blood flow was elevated in proportion. The presence of cor pulmonale did ...
Abstract Background Coronavirus disease 2019 (COVID-19) has become a global pandemic and is posing serious public health problem for almost all countries. Spontaneous pneumomediastinum, rare condition, usually seen in patients with underlying pulmonary pathology, infections, or mechanical ventilation. pneumomediastinum complication COVID-19 pneumonia. Case presentation We report case of spontan...
Emphysema is one of the disease conditions that comprise chronic obstructive pulmonary disease. Prothymosin α transgenic mice exhibit an emphysema phenotype, but the pathophysiological role of prothymosin α in emphysema remains unclear. Here we show that prothymosin α contributes to the pathogenesis of emphysema by increasing acetylation of histones and nuclear factor-kappaB, particularly upon ...
Pulmonary emphysema is a chronic obstructive disease, resulting from important alterations in the whole distal structure of terminal bronchioles, either by enlargement of air spaces or by destruction of the alveolar wall, leading to loss of respiratory surface, decreased elastic recoil and lung hyperinflation. For many years, the hypothesis of protease-antiprotease unbalance prevailed as the ce...
