Q

Bronchiectasis causes

A

Post infective - TB, Measles, pertussis,
Cystic fibrosis
Bronchial obstruction - lung CA, FB
Immune deficiency like IgA
ABPA
Kartagener
Yellow nail syndrome

17
Q

Paraneoplastic features of lung CA

A

SCC - PTHrp, clubbing, HPOA
Small cell - ADH, ACTH, Lambert - Eaton

18
Q

Most common bacteria in IE COPD

A

Haemophilus influenzae

19
Q

Which chronic infection is a contraindication for lung transplant in a Cystic fibrosis patient?

A

Infection with Burkholderia cepacia

20
Q

Alpha 1 AT deficiency

A

AAT is a protease inhibitor
Autosomal recessive/co-dominant
Heterozygous - PiMZ low risk but can pass to children
Homozygous PiZZ - usually disease

Treatment
No smoking
Bronchodilators and physio
Lung volume reduction surgery

21
Q

COPD management

A

First line is SABA

Poor control despite SABA :-
- No asthmatic features or negative steroid responsiveness - LABA + LAMA
- Asthmatic features - LABA + ICS. If poor response, LABA + LAMA + ICS

22
Q

Criteria for steroid responsiveness in COPD

A
  • previous diagnosis of asthma
  • Higher eosinophil count
  • substantial variation in FEV1 over time (atleast 400 ml)
  • substantial diurnal variation in PEFR (atleast 20%)
23
Q

Raised TLCO

A

Asthma
Pulm Hemorrhage
Polycythemia
Left to right shunts

24
Q

Low TLCO

A

Fibrosis
Pneumonia
PE
Pulm edema
Emphysema
Anemia

25
Q

Investigation for suspected adult asthma

A

FeNO +Spirometry with reversibility

26
Q

Pulm HTN is Pulm arterial pressure greater than?

A

25 mm Hg at rest or 30 mm Hg after exercise

27
Q

Most common type of cavitating lung CA

A

SCC

28
Q

Extrinsic allergic alveolitis (hypersensitivity pneumonitis)

A

Mainly type III hypersensitivity damage
Farmers lung: Saccharopolyspora rectivirgula
Malt workers lung: Aspergillus clavatus
Upper zone fibrosis
Oral steroids

29
Q

Oxygen dissociation curve

A

Left - Lower oxygen delivery, Lower acidity, Low temp, Low 2-3 DPG, HbF
Right - Raised oxygen delivery, Raised acidity, Raised temp and raised 2-3 DPG

30
Q

Pulmonary Eosinophilia causes

A

ABPA
Churg Strauss
Loeffler’s syndrome

Extrinsic allergic alveolitis DOES NOT CAUSE Eosinophilia

31
