Given that several different autoimmune diseases may be associated with silica dust exposure, silica dust may act to promote or accelerate disease development, requiring some other factor to break immune tolerance or initiate autoimmunity. The specific manifestation of this effect may depend on underlying differences in genetic susceptibility or other environmental exposures. …

 · Pigment-dispersion syndrome is an eye disorder that occurs when pigment granules that normally adhere to the back of the iris (the colored part of the eye) flake off into the clear fluid produced by the eye (aqueous humor).These pigment granules may flow towards the drainage canals of the eye, slowly clogging them and raising the pressure within the eye (intraocular …

This process causes issues related to inflammation from the patient's immune system response. Pneumoconiosis is considered an occupational lung disease because in most cases the dust particles are typically found in the workplace.

Most people get silicosis from a workplace where they inhale large amounts of silica dust. Learn more about the causes, risk factors, symptoms, treatments, and how to prevent this lung disease.

Breathing crystalline silica dust can cause silicosis, which in severe cases can be disabling, or even fatal. When silica dust enters the lungs, it causes the formation of scar tissue, which makes it difficult for the lungs to take in oxygen. There is no cure for silicosis. Silicosis typically occurs after 15–20 years of occupational exposure to respirable crystalline silica. Symptoms may or

 · Nocardiosis is a rare infectious disorder, that affects the brain, skin, and/or lungs. It occurs mainly in people with a weakened immune system but can affect anyone, and about one-third of infected people do not have any immune problems. [1] [2] [3]. This condition usually starts in the lungs and can spread to other body organs.

 · The body's immune system—made up of organs, tissues and cells—works to protect us from infection and disease. When a virus or other foreign substance is detected, the immune system kicks in. It makes molecules called antibodies to attack these invading substances known as antigens. This natural defense system is called an inflammatory …

Africa since the 1930s, dust was collected with a konimeter (Le Roux, 1970; Cherrie and Aitken, 1999). A small volume of air (, 5 cm . 3. captured in less than a second) was collected (impacted) onto a small area of a glass slide coated with adhesive. Total dust particles were counted and expressed as dust particles per cubic centimeter. Later, slides were heated to …

Breathing silica dust can put you at risk for a whole host of respiratory diseases from breathing tiny particles deep into your lungs. It can also set off an immune reaction that damages other tissues or organs. As a result, there is some evidence that silica dust exposure causes kidney failure, rheumatoid arthritis, and other autoimmune conditions. However, its relationship to …

Autoimmune Disease: a disease that occurs when a person's immune system begins attacking the person's own cells, marking them as pathogens.

Exposure to silica can lead to one of three disease patterns: (1) chronic simple silicosis, which usually follows more than 10 years of exposure to respirable dust with less than 30% quartz, (2) subacute/accelerated silicosis, which generally follows shorter, heavier exposures (ie, 2–5 years), and (3) acute silicosis, which is seen often following intense exposure to fine dust of high silica

pulmonary disease (including chronic bronchitis and emphysema), silicosis, lung cancer, and renal disease. Lung defence mechanisms against the very fine dust that penetrates to the alveolar oxygen exchange part of the lung can be overwhelmed by silica particles, which can be toxic to macrophages. Silicosis can result from exposure to RCS over
