Q

LENT score

A

LENT score used in malignant pleural effusion

  • Stratify patients to low (319 days survival), medium (130 days) and high (44 days) risk to estimated survival and hence guide treatment
  • Uses ECOG score, serum neutrophil to lymphocyte ratio and tumour type

Daily drainage increases spontaneous pleurodesis; 37% in 60 days. (AMPLE 2)

Talc administration through IPC improves the pleurodesis rate; 43% in 35 days

37
Q

A
39
Q

What is the main physiological mechanism of a normal PA-ao2 gradient?

A
40
Q

Mechanism of hypoxemia in ILD is mainly due to?

A

Diffusion limitation and V/Q mismatch

41
Q

Shunts and hypoxemia

A

Anatomic shunt: intracradiac shunt, pulmonary AVM, hepatpulmonary syndrome.

Physiologic shunt: atelectasis, disease with alveolar filling (pneumonia, ARDS)

These shunts causes extreme V/Q mismatch and are difficult to correct with supplemental oxygen. Whereas ILD, PE and COPD are caused by V/Q mismatch which can be corrected with low to moderate flow supplemental oxygen.

42
Q

Medications and REM sleep

A

Bupropion and Trazadone increases REM sleep

43
Q

Cheyne Stoke respiration

A

Periodic breathing from central sleep apnoea. Usually seen in patiemnts with LF.

Mx - treat the LVF, CPAP not helpful

44
Q

A

Can worsen catoplexy

A
49
Q

Constrictive Bronchiolitis Obliterans

A
50
Q

Galactomannan assay

A

moderate accuracy for diagnosis of invasive aspergillosis in immunocompromised patients. Test is more useful in patients who have haematological malignancy or who have undergone hematopoietic cell transplantation than in solid organ transplant recipients.

Galactomannan - major constituents of aspergilus cell wall - released during growth of hyphae- used to diagnose invasive aspergillosis in immunocompromised patients

51
Q

A

Haemophilus influenzae

52
Q

In 65 year old male with COPD, which of the following carries the greatest risk of death over the next 12 months?

A

Hospitalisation for an acute exacerbation of the disease = mortality of around 10% acutely. rising to 49% at one year

53
Q

BODE index

A

BMI, airflow Obstruction, Dyspnoea and Exercise capcity Index

54

A

Smoking cessation iis the intervention with greatest impact on mortality and rate fo FEV1 decline

55
Q

LTOT in COPD patients indication to commence:

A

PO2<55mmHg,

PO2 <60mmHg with pulmonary HT/RHF

Mortality benefit only > 16 hours/day

56
Q

A-a gradient

A

PAO2-PaO2

PAO2 = FiO2 x (Patm - Ph2o) - (PCO2 x 1.25)

57
Q

Contraindications to surgery in NSCLC

A
  • stage IIIb or IV
  • FEV1<1.5
  • malignant pleural effusion
  • tumour near hilum
  • vocal cord paralysis (Paralysis of a vocal cord, usually the left - implies extracapsular spread to mediastinal nodes, an indication of inoperability.)
  • SVC obstruction
58
Q

Eosinophilic bronchitis

A

Responds well to ICS and oral steroids -Th2 inflammation.

59
Q

ICS and LABA effect in COPD patients

A

Positive effect on: QoL, reduced freq and delays exacerbations, improved symptoms

BUT DOES NOT improve rate of decline or mortality

60
Q

Omalizumab

A

Anti-IgE

Good for allergic asthma

61
Q

Which lung cancer is most associated with smoking?

A

Small cell lung cancer!

This type is the most aggressive and rapidly growing of all the types.

Only 1% of these tumours occur in non-smokers. SCLC metastasize rapidly to many sites within the body and are most often discovered after they have spread extensively.

62
Q

Characteristics of a pulmonary nodule that make it more likely to be malignant?

A
  • larger lesions
  • irregular abd spiculated borders
  • Less density (eg. Hounsfield units <147)
  • doubling time between 20 - 400 days (eg. a nodule that has rapid doubling or VERY slow doubling unlikely to be malignant)
  • Ground glass appearance
63
Q

Vital capacity lung bvolume =

A

Tidal volume + Inspiratory reserve volume + expiratory reserve volume

64
Q

What carries a poor prognosis in patients with cystic fibrosis?

A
  • lowe FEV1
  • High CO2
  • High WCC
  • Females

Q

Which ILD resolves with smoking cessation?

A

73
Q

Predictors of nicotine dependence:

A
  1. smoking within minutes of waking
  2. higher number of cigarettes smoked per day
