SilicosisSilicosis is the irreversible lungs fibrosis caused by inhalation of sandy dust (quartz). When particles of sandy dust enter lungs, immune system cells, such as macro phagocytes, capture them. The enzymes emitted by these cells cause damage and tissue fibrosis of lungs. First zones of fibrosis represent tiny round small knots (simple nodular silicosis), but eventually, they can unite in the big masses (a nodal form of silicosis). In zones of fibrosis, there is no gas exchange and oxygen doesn’t come into the blood. Lungs lose elasticity, and breath demands great efforts. Control of the dust content on workplaces helps to prevent silicosis. If the amount of dust can’t be reduced as, for example, by the production of explosions, workers have to carry the gas masks providing access to clean air, or masks (respirators) which completely filter tiny particles.

It isn’t always convenient at all to use such protection during working in a dusty zone (for example, it is difficult for painters and welders to work in gas masks) so every time when it is possible, it is necessary to apply not sand but other abrasives. The workers contacting to sandy dust are recommended to pass regular radiological research of thorax exactly every 6 months to demolition men and each two to five years to other work that allows revealing a disease at an early stage. If an x-ray picture there are signs of silicosis, the doctor has to forbid the worker contact with sand. If silicosis is identified it is better to consult the doctor. After the consultation, you may order necessary preparations for treatment via Canadian Pharmacy Mall.

At patients with simple nodular silicosis, the difficulty of breath is absent, but there can be a cough and sputum discharge as the top airways are irritated (there is chronic bronchitis). At a nodal form of a silicosis cough, excessive sputum discharge and severe dyspnea are noted. At first, it arises only during physical activity but then appears even during rest. The condition of respiratory system worsens within two to five years after the person ceases to work with sand. Injury of lungs increases the load of heart that can lead to heart failure and death. At infection with the tuberculosis microbacteria cause tuberculosis the probability of development of this disease and in such patients, silicosis is three times higher, than at the others.

Silicosis, long ago a known professional pulmonary disease, develops in people who many years breathe sandy dust. The miners extracting metal, sandblasters and handlers of granite, workers of foundry shops and potters have close contact with sandy dust. Usually, symptoms appear only after 20-30 years of contact with dust. However at representatives of a number of professions (demolition men, and workers of grinding production), whose working conditions assume contact with the sandy dust containing in the air in high concentration, can appear earlier than in ten years.

Silicosis is impossible to be treated. However, if the person at an early stage of illness stops contact with sand, progressing of silicosis can stop. At difficulty of breath, the preparations are used as at chronic obstructive diseases of lungs, for example, drugs, expanding airways and facilitating release them from sputum. As patients with silicosis have a high risk of development of tuberculosis, they have to pass the regular inspections including skin tuberculin test.
