Define pneumoconiosis
Any pulmonary diseases with
The 2 types of pneumoconiosis include:
Examples of collagenous pneumoconioisis are:
Examples of non-collagenous pneumoconiosis are:
Stages of pathogenesis of pneumoconiosis:
Dust particles are engulf them and occurs occurs More particles cause stimulation
Define silicosis
A type of that occurs with people handling
State the symptoms for each form of silicosis:
Mild: Moderate: , , Severe: ,
What are the forms of diagnosis for silicosis?
Examples of differential diagnosis for silicosis:
Diffuse Disseminated Disseminated Systemic
State the treatment for silicosis:
Avoid Sprays = , Extreme cases =
Silicosis can be prevented by:
Wearing a
Asbestosis is a , silicosis caused by inhaling (hydrogenated ).
Sources of asbestosis are:
, , and products boxes
Pathogenesis of asbestosis:
Asbestos fibres are They are deposited at the This causes These activated macrophages release This initiates (usually in the ) Pre-bronchial fibrosis with may the airway and cause air flow
Clinical manifestation of asbestosis:
Initial symptoms: , , Later symptoms: , with different quantity and quality, ,
On auscultation:
Radiography: - or irregular opacities in the and lung zones structures = signs of in lung area
X-ray = (fibrosis, hyalinosis, calcinosis)
Diagnosis of asbestosis:
history (dust exposure) (irregular and subpleural opacities) autopsy lavage fluid investigation
Differential diagnosis of asbestosis, talcosis and kaolinosis:
Disseminated Disseminated Systemic
Treatment for asbestosis, talcosis, kaolinosis includes:
drugs
Prevention of asbestosis, talcosis and kaolinosis includes:
dust concentration in and
Talcosis is the inhalation of (hydrogenated ) and . This includes , and . Its sources are: , and
Pathogenesis of talcosis is the same as asbestosis but leads to and .
Clinical manifestations of talcosis are:
progressing and similar to asbestos On auscultation: in lung areas On chest x-ray: with opacities appear later
Kaolinosis is a caused by inhalation of . Kaolin is a e.g. quartz. Its sources include: production, and production
Clinical manifestations of kaolinosis:
Early stage: no pulmonary symptoms (develop slowly and later) On chest x-ray:
Coal worker's pneumoconiosis is caused by to dust and .
Pathogenesis of coal worker's pneumoconiosis includes:
enters the lungs and reaches the The dust is engulfed by and accumulates in the An is activated growth factors and are released This causes - leading to and
Clinical manifestations are: , and Severe lung impairment leads to , X-ray: in early infection, nodules form in later infection Differential diagnosis: ,
