Q

What examination findings would be found in a raised hemidiaphragm?

A

SAME AS EFFUSION
Mediastinal shift away if big, stony dull percussion, decreased or absent breath sounds, decreased or absent vocal resonance
Use a CXR to differentiate
Due to phrenic nerve palsy caused by thoracic surgery, trauma, malignancy

Q

What do you look for in a patient’s hands in a resp. exam?

A
  • Clubbing = ILD, CF, Ca, Bronchiectasis
  • Peripheral Cyanosis = PVD
  • Tar Staining = Smoking/Coal Mining History
  • C02 Retention Flap = Resp. Failure
  • Koilonychia = Iron Deficiency Anaemia
  • 1st webspace wasting - Pancoast Tumour
  • Tremor = excessive use of beta-agonists or theophylline bronchodilators
  • Pulse = bounding in C02 retention (C02 acts as vasodilator)

16
Q

When is the trachea deviated towards a pathology?

A
  • Lobar collapse

- Pneumonectomy

17
Q

When is the trachea deviated away from a pathology?

A
  • Large pleural effusion

- Tension Pneumonthorax

18
Q

What does each percussion note show?

Resonant, Hyper Resonant, Dull, Stony Dull

A

Resonant - normal
Hyper Resonant - Pneumothorax, Emphysematous Lung
Dull - Lung separated from chest wall e.g. pleural fluid/consolidation/collapse
Stony Dull - Pleural Effusion

19
Q

When does reduced vesicular breathing occur?

A

If there is a thick chest wall e.g. pleural thickening or if there is a reason for conduction of sound to be reduced e.g. emphysema

20
Q

When does bronchial breathing occur?

A

Associated with pneumonic consolidation. Also at border between lung and pleural effusion (due to compressed lung)
Breath sounds are low and blowing, inspiration and expiration are similar length, audible gap between inspiration and expiration

21
Q

What are the causes of crackles?

A
  • Early inspiration = small airway disease such as bronchiolitis
  • Mid-inspiration = pulmonary oedema
  • Late inspiration = interstitial lung disease, COPD, pneumonia
  • Throughout inspiration and expiration = bronchiectasis
22
Q

What are the differentials for consolidation on CXR?

A
  • Pneumonia
  • TB
  • Lung Cancer
  • Lobar Collapse
  • Haemorrhage
23
Q

Explain the CURB65

A 
C - confusion = MMT 2 or more points worse
U - Urea > 7.0
R - Resp. Rate >=30
B - BP >=90 systolic or >=60 diastolic
65 - Age over 65
24
Q

What are the causes of a non-resolving pneumonia?

A

CHAOS
C - Complication = empyema, lung abscess
H - Host = Immunocompromised
A - Antibiotic = Inadequate dose, poor oral absorption
S - Second Diagnosis = PE, Cancer, Organising Pneumonia

25
Q

What are the differential diagnoses for haemoptysis?

A

1) Infection
- Pneumonia
- TB
- Bronchiectasis/CF
- Cavitating lung lesion
2) Malignancy
- Lung Cancer
- Metastases
3) Haemorrhage
- Bronchial Artery Erosion
- Vasculitis
- Coagulopathy
4) Other
- PE

26
Q

What are the causes of a transudate pleural effusion?

Pleural protein <30g/L

A

Common - heart failure, cirrhosis, hypoalbuminaemia (nephrotic syndrome or peritoneal dialysis)
Less common - hypothyroidism, mitral stenosis, PE
Rare - constrictive pericarditis, SVC obstruction, Meig’s Syndrome

27
Q

What are the causes of an exudate effusion?

Pleural protein >30g/L

A

Common - malignancy, infection e.g. TB, HIV
Less Common - inflammatory e.g. RA, pancreatitis, connective tissue disease
Rare - yellow nail syndrome, fungal infections, drugs

28
Q

What is the Light’s Criteria?

A

If pleural fluid protein level is between 25 and 35g/L then use the Light’s Criteria.
It is exudate if one or more of the following:
- pleural fluid/serum protein >0.5
- pleural fluid/serum LDH >0.6
- pleural fluid LDH > 2/3 of the upper limit of normal
