The researchers shared their findings in their paper, entitled "(https://jamanetwork.com/journals/jama/article-abstract/2747669) Association Between Long-term Exposure to Ambient Air Pollution and Change in Quantitatively Assessed Emphysema
and Lung Function ," published in the peer-reviewed journal JAMA.
models have a number of advantages, such as simple operation, inexpensive, and high efficiency.
Over 10 years on average, the study found long-term exposure was linked to an increased percentage of emphysema
on a CT scan.
"To our knowledge, this is the first longitudinal study to assess the association between long-term exposure to air pollutants and progression of per cent emphysema
in a large, community-based, multi-ethnic cohort," said Meng Wang, study's first author.
, usually associated with cigarette smoking, is a chronic disease in which lung tissue is destroyed and unable to effectively transfer oxygen in the body.
Cigarette smoking is the best known cause of emphysema
Wide subcutaneous emphysema
and crepitus extending scalp to inguinal region were determined.
We present the case of a patient with pneumomediastinum and diffuse subcutaneous emphysema
, involving the neck, shoulder, and lateral chest wall following traumatic rib fracture secondary to a minor blunt chest trauma.
The program detects the areas of emphysema
(low attenuation areas with a threshold of -950 HU) and allows the evaluation of the type and distribution of emphysema
On follow-up examination the next day, the periorbital emphysema
was substantially reduced and the globe could be examined (Figures 4, 5).
We present a rare case of a patient diagnosed with massive subcutaneous emphysema
extending from the superior left eyelid to the diaphragm.
Collectively, chronic bronchitis, obstructive bronchitis, and emphysema
are called COPD or chronic obstructive pulmonary disease.
