Respiratory Flashcards
lung cancer associated with Cushings/paraneoplastic syndromes
very fast growing
small cell lung cancer
lung cancer associated with gynacomastia, in women
adenocarncinoma
lung cancer most associated with smoking, and causes hypercalcaemia
squamous cell carcinoma
progressively worsening dyspnoea, cough in older men, smoker
fine end inspiratory crackles
pulmonary fibrosis
pulmonary fibrosis Ix
CT chest, honeycomb appearance
unilateral pleural effusion, protein level >30, causes????
exudative
cancers; SLE, rheumatoid, pancreatitis, infection
bilateral pleural effusion, protein <30
transudative
due to increased cap pressure (CHF); damaged basement membrane (renal dysfunction)
bilateral pulmonary infiltrates/opacities
bibasal crackles
diffuse alveolar damage
hyaline membrane formation
Acute respiratory distress syndrome
pathophys of ARDS
severe inflammatory response in lungs, 2ndary to lung illness
non cariogenic pulmonary oedema
damage to alveolar-capillary membrane causes fluid to move into the lung -> pulmonary oedema
general signs of sarcoidosis
dry cough, dyspnoea
lymphadenopathy, enlarged parotid gland
bilateral bells palsy
anterior uveitis
erythema nodosum
vena cava syndrome diagnostic tool
positive pembertons sign
peripheral cyanosis, dyspnoea, cough, systemically unwell
epigastric pain, high lipase
ARDS associated with pancreatitis
Mx of acute bronchitis
avoid empirical ABs
CRP 20-100: delayed prescription
CRP >100: doxycycline
ECG in COPD
P pulmonale, high P waves in inf leads, right axis deviation, low voltage QRS
chronic asthma Mx
- salbutamol
- ICS (beclometasone)
- add LTRA (montelukast)
- add LABA (salmetarol)
- add LAMA (triotropium)
acute asthma Mx
- salbutamol
- oral prednisolone
croup Px and Mx
barking cough, infection of upper airway
dexamethasone
Mx of lung abscess
IV then oral ABs for 8 weeks. clindamycin + ceftriaxone
Mx of chronic COPD
- salbutamol
- ICS (beclometasone)
- LABA + LAMA
Dx of CF in newborns and adults
Newborns = heel prick
Adults = sweat test
Px of pneumocystis pneumonia, Ix, Mx
associated with HIV/immunocompromised
bifilar infiltrates on CXR
Mx: co-trimoxazole
Px and Ix of TB
fever, weight loss, night sweats, S asians
patchy opacifications in upper lungs on CXR
progressive cough, large amounts of yellow sputum, haemoptysis
bronchiectasis
lung cancer associated with hypercalcemia
squamous
lights criteria is used for…
classifying pleural effusions
lights criteria
pleural fluid : serum protein = >0.5
pleural fluid : serum LDH = >0.6
pleural fluid LDH is >2/3 of upper limit
stony dullness on percussion/auscultation
pleural effusion
hyper-resonant percussion
COPD
