Qualitative and Quantitative Assessment of Emphysema Using Dark-Field Chest Radiography.
Radiology, 2022Background Dark-field chest radiography allows for assessment of lung alveolar structure by exploiting wave optical properties of x-rays. Purpose To evaluate the qualitative and quantitative features of dark-field chest radiography in participants with ...

A vision transformer for emphysema classification using CT images
Physics in Medicine and Biology, 2021Objective. Emphysema is characterized by the destruction and permanent enlargement of the alveoli in the lung. According to visual CT appearance, emphysema can be divided into three subtypes: centrilobular emphysema (CLE), panlobular emphysema (PLE), and

AbstractThis review of the medical literature on emphysema before and during the nineteenth century clearly demonstrates that the disease was highly prevalent before modern times. The alleged increase in the prevalence of emphysema during recent decades—on the basis of official death certifications—is a statistical illusion.

The pathophysiology of emphysema is best explained on the basis of decreased pulmonary elastic recoil. At any pleural pressure, the lung volume is higher than normal. Additionally, the altered relation between pleural and alveolar pressure facilitates expiratory dynamic compression of airways.

An 87 year-old woman with a history of hypertension, type 2 diabetes and post-menopausal osteoporosis presented with a 5-day history of low-grade intermittent fever, epigastric pain and shortness of breath. At admission, patient was normotensive but tachycardic (HR 106 beats/min) and tachypneic (RR 26 breaths/min), and oxygen saturation was 96% while ...

ter to its stimulating effects until, eventually, the center no longer responds to the presence of carbon dioxide. Thus, in chronic emphysema, the respiratory center-rather than responding to carbon dioxide concentrations-is stimulated by the chemoreceptors which respond to low oxygen tensions of the blood.

Marked erythrocytosis is frequently seen in hypoxia due to high altitudes and cyanotic congenital heart disease (Hurtado, Merino and Delgado, 1945) but is relatively uncommon in association with chronic respiratory failure (Baldwin, Cournand and Richards, 1949). This discrepancy has exercised a number of writers.

Emphysema: looking beyond alpha-1 antitrypsin deficiency
Expert Review of Respiratory Medicine, 2019Introduction: Distinct pathologies can cause chronic obstructive pulmonary disease (COPD). Emphysema is a COPD-phenotype characterized by destruction of lung parenchyma.

Summary Criteria for the x-ray diagnosis of gross widespread emphysema with air trapping are put forward, and the variations of x-ray appearances which fulfil these criteria are described. The reliability and prognostic value of the x-ray findings are discussed.
