High-resolution CT image showing ground-glass opacities in the periphery of both lungs in a patient with COVID-19 (red arrows). The adjacent normal lung tissue with lower attenuation appears as darker areas. Ground-glass opacity (GGO) is a finding seen on chest x-ray (radiograph) or computed tomography (CT) imaging of the lungs.
Pulmonary fibrosis is perpetuated by aberrant wound healing, rather than chronic inflammation. [15] It is the main cause of restrictive lung disease that is intrinsic to the lung parenchyma. In contrast, quadriplegia [16] and kyphosis [17] are examples of causes of restrictive lung disease that do not necessarily involve pulmonary fibrosis.
Coughing is a common symptom of COVID-19, but sometimes it lingers even after the infection clears up. ... and because it causes inflammation in the airways, COVID-19 can cause a cough,” Dr ...
Interstitial lung disease (ILD), or diffuse parenchymal lung disease (DPLD), [3] is a group of respiratory diseases affecting the interstitium (the tissue) and space around the alveoli (air sacs) of the lungs. [4] It concerns alveolar epithelium, pulmonary capillary endothelium, basement membrane, and perivascular and perilymphatic tissues. It ...
Figure B shows fibrosis (scarring) in the lungs. The inset image shows a detailed view of the fibrosis and how it damages the airways and air sacs. [1] Specialty: Pulmonology: Symptoms: Shortness of breath, dry coughing [1] Complications: Pulmonary hypertension, heart failure, pneumonia, pulmonary embolism [1] Usual onset: Gradual [1] Causes ...
Restrictive lung diseases are a category of extrapulmonary, pleural, or parenchymal respiratory diseases that restrict lung expansion, [2] resulting in a decreased lung volume, an increased work of breathing, and inadequate ventilation and/or oxygenation. Pulmonary function test demonstrates a decrease in the forced vital capacity.
(Reuters) - Merck said on Monday its drug, Winrevair, helped significantly reduce the risk of death in patients with a rare condition which causes high blood pressure in the lungs, months after it ...
Fibrothorax may also occur without a clear underlying cause, in which case it is known as idiopathic fibrothorax. A technique called pleurodesis can be used to intentionally create scar tissue within the pleural space, usually as a treatment for repeated episodes of a punctured lung, known as a pneumothorax, or for pleural effusions caused by ...
