Cor pulmonale (right ventricle heart disease).Cyanosis, pallor along upper parts of body (blue skin).In advanced cases, the following may also occur: Gradual dark shallow rifts in nails eventually leading to cracks as protein fibers within nail beds are destroyed.Tachypnea (rapid breathing) which is often labored,.Cough, often persistent and sometimes severe.Dyspnea (shortness of breath) exacerbated by exertion.Miner's lung with silicosis and tuberculosis ( Basque Museum of the History of Medicine and Science, Spain)īecause chronic silicosis is slow to develop, signs and symptoms may not appear until years after exposure. In 1938, the United States Department of Labor, led by then Secretary of Labor, Frances Perkins, produced a video titled ' Stop Silicosis' to discuss the results of a year-long study done concerning a rise in the number of silicosis cases across the United States. The pneumatic hammer drill was introduced in 1897 and sandblasting was introduced in about 1904, both significantly contributing to the increased prevalence of silicosis. With industrialization, as opposed to hand tools, came increased production of dust. In 1713, Bernardino Ramazzini noted asthmatic symptoms and sand-like substances in the lungs of stone cutters. Agricola, in the mid-16th century, wrote about lung problems from dust inhalation in miners. The recognition of respiratory problems from breathing in dust dates to ancient Greeks and Romans. The name silicosis (from the Latin silex, or flint) was originally used in 1870 by Achille Visconti (1836–1911), prosector in the Ospedale Maggiore of Milan. Silicosis resulted in at least 43,000 deaths globally in 2013, down from at least 50,000 deaths in 1990. Using workplace controls, silicosis is almost always a preventable disease. It may often be misdiagnosed as pulmonary edema (fluid in the lungs), pneumonia, or tuberculosis. Silicosis (particularly the acute form) is characterized by shortness of breath, cough, fever, and cyanosis (bluish skin). It is marked by inflammation and scarring in the form of nodular lesions in the upper lobes of the lungs. Silicosis is a form of occupational lung disease caused by inhalation of crystalline silica dust.
