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: ,
