ASbestos Flashcards
most common form of asbestos-related lung disease
pleural plaques
Pleural plaques require regular follow-up. TRUE/FALSE
FALSE
benign and do not undergo malignant change
How soon after work with asbestos do pleural plaques occur?
generally occur after a latent period of 20-40 years.
What change does asbestosis cause in the lungs
Lower lobe fibrosis
Length of asbestos exposure is directly related to severity of asbestosis. TRUE/FALSE
TRUE
(unlike mesothelioma where small exposure can cause poor disease)
How long after working with asbestos does asbestosis usually present?
15-30 years
Clinical features of asbestosis?
- dyspnoea
- reduced exercise tolerance
- clubbing
- bilateral end-inspiratory crackles
Results found on pulmonary function tests in asbestosis
- restrictive pattern with reduced gas transfer
Management of asbestosis
treated conservatively - no interventions offer a significant benefit.
What is mesothelioma? from which type of asbestos does this usually occur?
- malignant disease of the pleura
- Crocidolite (blue) asbestos is the most dangerous form.
Clinical features of mesothelioma
- progressive breathlessness
- chest pain
- pleural effusion
Treatment options in mesthelioma
- palliative chemotherapy
- limited role for surgery and radiotherapy
Prognosis of mesothelioma from diagnosis
median survival from diagnosis of 8-14 months.
Mesothelioma is the most common form of cancer associated with asbestos exposure. TRUE/FALSE?
FALSE
lung cancer is actually the most common form of cancer associated with asbestos
- increased risk with cigarette smoking
