Byssinosis [n 1] is an occupational lung disease caused by inhalation of cotton or jute dust in inadequately ventilated working environments and can develop over time with repeated exposure. [ 2 ] [ 3 ] Byssinosis commonly occurs in textile workers who are employed in yarn and fabric manufacture industries.
Fibrothorax is a medical condition characterised by severe scarring and fusion of the layers of the pleural space surrounding the lungs resulting in decreased movement of the lung and ribcage. [1]
In radiology, the steeple sign is a radiologic sign found on a frontal neck radiograph where subglottic tracheal narrowing produces the shape of a church steeple within the trachea itself. [ 1 ] [ 2 ] The presence of the steeple sign supports a diagnosis of croup , usually caused by paramyxoviruses . [ 3 ]
Byssinosis – Byssinosis is caused by cotton dust inhalation and typically demonstrates a different pattern of lung abnormalities from most other pneumoconiosis. [1] Chalicosis – fine dust from stonecutting; Silicosiderosis (also sometimes called iron miner's lung [10]) – mixed dust containing silica and iron [11]
Idiopathic interstitial pneumonia (IIP), or noninfectious pneumonia [1] are a class of diffuse lung diseases.These diseases typically affect the pulmonary interstitium, although some also have a component affecting the airways (for instance, cryptogenic organizing pneumonitis).
A pulmonary consolidation is a region of normally compressible lung tissue that has filled with liquid instead of air. [1] The condition is marked by induration [2] (swelling or hardening of normally soft tissue) of a normally aerated lung.
A pleural effusion is accumulation of excessive fluid in the pleural space, the potential space that surrounds each lung.Under normal conditions, pleural fluid is secreted by the parietal pleural capillaries at a rate of 0.6 millilitre per kilogram weight per hour, and is cleared by lymphatic absorption leaving behind only 5–15 millilitres of fluid, which helps to maintain a functional ...
A lung nodule or pulmonary nodule is a relatively small focal density in the lung.A solitary pulmonary nodule (SPN) or coin lesion, [1] is a mass in the lung smaller than three centimeters in diameter.
