  1. Bronchoarterial ratio >1
  2. Lack of tapering of bronchi
  3. Distance from airway to costal pleural surface <1cm
22
Q

What is the first-line treatment for histoplasmosis?

A

Itraconazole

23
Q

What is the gold standard investigation for pulmonary HTN?

A

Right heart catheterisation

24
Q

What is the criteria for lung transplant in COPD?

A

FEV1 <20% predicted despite maximal medical therapy

25
Q

What is the correct position for a chest drain?

A

4-6th intercostal space, mid-axillary line

26
Q

What are the CURB65 criteria?

A
C - confusion
U - urea >7
R - RR >30
B - BP <90/60
65
27
Q

Sudden haemoptysis in bronchiectasis is likely due to what?

A

Bronchial circulation bled –> treat with embolization of the bronchial artery

28
Q

What may provide symptoms relief in asbestosis?

A

Oxygen

29
Q

After amoxicillin as a first-line agent, what are the second-line oral agents for CAP?

A

Doxycycline or levofloxacin

30
Q

Which chemo agent used in lung cancer is used for people with an eGFR< 30?

A

Carboplatin

31
Q

Why is FEV1 preserved in restrictive lung disease?

A

Because the elastic recoil is normal, maintaining appropriate forced expiration. Hence FEV1/FVC overall increases (FVC reduces and FEV1 = maintained)

32
Q

Which organism is responsible for whooping cough, and if it causes bronchitis, which bx should be used?

A

Bordetella pertussis –> Azithromycin

33
Q

Which organism causes rust-coloured sputum?

A

Streptococcus pneumoniae

34
Q

What are the first-line Abx choices in HAP?

A

Non-severe features - Co-amox, PO

Severe/risk of MDR - Taz, IV

35
Q

Which agent is used in a bronchoprovication test?

A

Methacholine

36
Q

How is chronic hypersensitivity pneumonitis managed?

A

Low dose oral prednisolone

37
Q

How should asthma be investigated in adults?

A

FeNO test + spirometry with reversibility

38
Q

What condition is Lambert-Eaton Myasthenic Syndrome associated with?

A

SCLC

39
Q

What is the pattern of muscle weakness associated with Lambert-Eaton Myasthenic Syndrome?

A

Muscle weakness in LEMS mainly affects the proximal muscles, with symptoms being worst in the morning, improving with exercise

40
Q

What is Caplan syndrome?

A

A type of pulmonary fibrosis, seen in RA patients, usually in coal miners/people who have breathed in a lot of dust.
Presents as multiple, round, well-defined nodules.
