Resp Flashcards
Causes of raised TLCO?
asthma
pulmonary haemorrhage
L->R cardiac shunts
polycythaemia
most common organism of infective exacerbation of COPD?
haemophilus influenza
Treatment of ABPA?
oral steroids: high dose pred in acute management followed by low -> medium dosing for maintenance
- tapered off over 3-12 mo.
- pred decreases the risk of bronchiectasis
causes of basal pulmonary fibrosis?
- idiopathic
- asbestosis
- connective tissue disorders e.g. SLE
- drug induced: amiodarone, bleomycin, methotrexate
causes of apical pulmonary fibrosis?
- EAA
- coal worker’s pneumoconiosis
- silicosis
- sarcoidosis
- ank spond
- histiocytosis
- TB
Contraindications to surgery for lung cancer?
- stage IIIb / IV (mets present)
- FEV1 < 1.5L*
- malignant pleural effusion
- tumour near hilum
- vocal cord paralysis
- SVC obstruction
uveoparotid fever: parotid enlargement, fever, uveitis secondary to sarcoidosis?
Heerfordt’s syndrome
acute form of sarcoidosis characterised by bilateral hilar lymphadenopathy, erythema nodosum, fever, polyarthralgia?
Lofgren’s syndrome
Source of bleeding in cases of severe haemoptysis requiring treatment?
- bronchial arteries - 90%
2. pulmonary arteries - 5%
pharmacological prophylaxis of acute mountain sickness
1st line: acetazolamide
carbonic anhydrase inhibitor which acts on the kidneys to generate a primary metabolic acidosis. A compensatory respiratory alkalosis occurs in response, resulting in hyperventilation and improved oxygenation.
Management of high altitude cerebral oedema (HACE)?
- descent
- dexamethasone
Management of high altitude pulmonary oedema?
- descent
- nifedipine, dexamethasone, acetazolamide, phosphodiesterase type V inhibitors*
- oxygen if available
Mepolizumab
Anti-IL5 monoclonal antibody
- down-regulates eosinophil activity
- significantly improve symptoms in resistant asthma
Omalizumab
Anti IgE monoclonal antibody
- effective in treating resistant asthma with evidence of raised IgE and allergic symptoms
Treatment of extensive small cell lung cancer?
Palliative chemotherapy
