Damage and loss of the tiny sensory hair cells in the inner ear (that can be caused by different factors such as noise damage, medications, and age) may be commonly associated with the presence of tinnitus. One of the preventable causes of tinnitus is excessive noise exposure. In some instances of noise exposure, tinnitus can be noticed even before hearing loss develops, so it should be considered a warning sign and an indication of the need for hearing protection in noisy environments.
Blastomyces dermatitidis is a fungus that has been associated with pleural effusions in 3% to 21% of patients with pulmonary blastomycosis in different case series (11, 69). The pleural effusions are most commonly small and cause only blunting of the costphrenic angle on x-ray.denovirus is the most common viral cause of atypical pneumonia. Pleural effusions occur in anywhere from 15% to 62% of patients (24, 71). The effusions are often bilateral and are accompanied by a diffuse parenchymal infiltrate typical of a viral pneumonia.
