Asbestos-related diseases are disorders of the lung and pleura caused by the inhalation of asbestos fibres. Asbestos-related diseases include non-malignant disorders such as asbestosis (pulmonary fibrosis due to asbestos), diffuse pleural thickening, pleural plaques, pleural effusion, rounded atelectasis and malignancies such as lung cancer and malignant mesothelioma.
Pleural plaques are patchy collections of hyalinized collagen in the parietal pleura. [2] They have a holly leaf appearance on X-ray. [1] They are indicators of asbestos exposure, and the most common asbestos-induced lesion. [3] They usually appear after 20 years or more of exposure and never degenerate into mesothelioma.
Labrador lung (found in miners in Labrador, Canada) – mixed dust containing iron, silica and anthophyllite, a type of asbestos; Stannosis – tin oxide; Talcosis – talc; Baritosis - a benign type of pneumoconiosis caused by barium inhalation; it typically causes little or no overgrowth, hardening, and/or fibrosis. [12] Mixed-dust ...
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 ...
On radiological studies, a pleural pseudotumor is visualized as a biconcave or lenticular lesion using conventional chest x-rays and CT scans. The lesion is most commonly located in the minor (horizontal) fissure of the lung. A pleural pseudotumor is also associated with the presence of dependent pleural effusions. [9]
The presence of pleural plaques may provide supportive evidence of causation by asbestos. Although lung biopsy is usually not necessary, the presence of asbestos bodies in association with pulmonary fibrosis establishes the diagnosis. [27] Conversely, interstitial pulmonary fibrosis in the absence of asbestos bodies is most likely not ...
Spinosad: This flea treatment may cause ivermectin to become toxic. In a study, neurotoxic signs were found in dogs, so if she is using this medication, it can cause her to fall over and have ...
In some cases of pleural effusion, the excess fluid becomes infected and turns into an abscess. This is called an empyema. Pleural effusion involving fibrinous exudates in the fluid may be called fibrinous pleurisy, which sometimes occurs as a later stage of pleurisy. A person can develop a pleural effusion in the absence of pleurisy.
