Silicosis (Silicosis)


Silicosis (Silicosis) is such a tract diseases respiratory due to inhaling dust silica, which causing inflammation and tissue formation the scarring on the lung-lung.

There are three types of silicosis:

Silicosis Chronic simplex, occur a result the exposure a number of small of dust silica in the long run (more than 20 years).

Nodules-nodules chronic inflammation and tissue scar due to silica formed in the lung-lung and lymph nodes chest.

Silicosis Akselerata, occurs after exposure to by a a number of silica who more a lot during of time who more shorter (4-8 years old).

Inflammation, formation scar tissue and symptom-symptoms are occur more quickly.

Silicosis Acute, occur a result the exposure silicosis in a amounts a very large, within time which more shorter. The lungs very inflamed and so occupied by the fluid, so that the arise shortness of breath is superb and levels blood oxygen who low.

On silicosis simplex and akselerata could occur fibrosif progressive massive. Fibrosis this happens a result formation scar tissue and cause damage to the structure of the lung who normal.


Silicosis occurs in people-people who have inhaled dust silica during several years. Silica is the main element of the sand, so that exposure usually occurs in:

– Laborer metal mines,

– Worker cutters stone and granite,

– Metal foundry workers, and

– Maker pottery.

Usually symptoms do arise after exposure for 20-30 years. But on blasting sand, the manufacture terowogan and manufacture of tool pengampelas soap, wherein levels of silica which produced very high, symptoms can be arise within time of less than 10 years.

If inhaled, powders silica incoming into the lungs and cell cleanser (eg macrophages) akan digest it. Enzymes produced by cells cleaners cause scarring of the lungs. In the beginning, area grated this is only is an bungkahan rounded who thin (silicosis noduler simplex). Finally, they join become masses who large (silicosis konglomerata). Area this scar tissue can not stream oxygen into the blood normally. The lungs become less pliable and sufferers susceptible to interference respiratory.


Patients with silicosis nodular simple do not have breathing problems, but they can suffer from cough with phlegm because channels respiratory irritation (bronchitis). Silicosis konglomerata could cause the cough with phlegm and shortness of breath. At first, shortness of breath occurs only during activity, but eventually packed arise even at rest.

Respiratory complaints could deteriorate within time 2-5 years after sufferer stops working. Damage in the lungs of can be about cardiac and causes the heart failure that can result fatal. IF exposed by organism the cause of tuberculosis (Mycobacterium Tuberculosis, sufferers silicosis have a risk 3 times greater for the suffer tuberculosis.

Additional symptoms that may be found, mainly on silicosis acute:

– Fever,

– Cough,

– Weight loss, and

– Disruption respiratory who heavy.


Usually akan asked questions in detail regarding the types of work, hobbies and other events which likelihood large is a source the exposure of silica.

Examination who conducted:

Rontgen chest (visible picture of pattern nodules and scar tissue)

Pulmonary function tests

Tests PPD (for TBC).


There is no specific treatment for silicosis. To prevent increasingly worsening of disease, very important for eliminate the source the exposure. Supportive therapy consist of suppressing drugs cough, bronchodilators and oxygen. If occurs an infection, could be given antibiotics.

Another thing who need to be consider are:

– Restrict for exposure to silica

– Quit smoking

– Undergo skin tests to TBC routinely.

Sufferers silicosis has a a high risk suffer Tuberculosis (TBC), so it is recommended for undergo skin tests regularly every year. Silica allegedly affects the’s immune system the body against bacterium the cause of TBC. If the result is positive, given the drug anti TBC.


Supervision against in the working environment can help prevent the occurrence of silicosis. If dust not can controlled, (as does within industry blasting), then the worker must wear equipment that give clean air or the containment.

Workers exposed to silica, must undergo a routine chest x-rays. For worker explosives sand every 6 month and for other workers every 2-5 year, so the disease is can know at an early. If x-rays showed silicosis, it is recommended to avoid exposure to silica.
