Q

What organisms cause typical community acquired pneumonia?

A

22
Q

What kind of organism is strep pneumonia?

A

23
Q

what is the second commonest cause of death in the UK?

24
Q

Is a CXR abnormal in pneumonia?

A

Always abnormal

25
What is seen in a CXR of someone with pneumonia?
Pulmonary shadowing/consolidation
26
What does the added sound of crackling usually indicate?
Infection
27
What is bronchiectasis?
The dilation of bronchi producing sepsis in the chest
28
What are 8 symptoms of bronchiectasis?
``` Daily cough Daily copious purulent (yellow, green or opaque sputum indicating the presence of neutrophils) Occasional haemoptysis Frequent chest infections Wheezing Dyspnoea Tiredness Flitting chest pains ```
29
What are the signs of bronchiectasis?
Finger clubbing | Lung crackles on inspiration and expiratoin
30
Can bronchiectasis be cured?
No
31
How is empyema distinguished from a simple effusion?
The fluid can be collected and sampled and is found to be pus
32
Why does the infected fluid need to be drained and not treated with antibiotics?
Because antibiotics do not penetrate well into the pleural cavity
33
What investigations are done for bronchiectasis?
Sputum culture Spirometry CXR High resolution CXR are the main diagnostic tests
34
What infects the fluid in empyema?
Micro-organism
35
How is an abscess in the lung removed?
Long-term antibiotics, Sometimes the abscess must be drained by a surgeon or radiologist
36
What are some of the common micro-organisms causes of LRTIs?
Streptococcus pneumonia (50%), staphylococcus aureus
37
What are features of streptococcus pneumonia?
``` Abrupt onset High pyrexia/rigors Pleuritic chest pain Cough with purulent (green) sputum Hypotension and cyanosis Septicaemia ```
38
What is shown in CXR of streptococcus pneumonia?
Classically lobar and often patchy shadowing
39
What is the treatment for streptococcus pneumonia?
IV benzyl penicillin, amoxicillin, oral ampicillin
40
If the person is allergic to penicillin what antibiotics should be used?
Macrolide and Clarithromycin
41
What is the treatment for empyema?
Chest drain, IV antibiotics
42
What organisms are more likely to result in cavitating pneumonia?

43
What are the causes of Bronchiectasis?
``` Idiopathic Immotile Cilia Syndrome CF Childhood infections such as measles ABPA ```
44
What is the treatment for bronchiectasis?
Chest physiotherapy Prompt treatment of infections with appropriate antibiotics , May require inhaled therapy including beta2 agonist and inhaled corticosteroid
45
What does CURB65 stand for?
``` C = confusion U= blood urea>7 ``` Respiratory rate >30 B = diastolic blood pressure <60 65 = age>6
46
What are the main features of bronchiectasis?
Dilated and damaged bronchi
47
What are the signs of pneumonia?
``` Pyrexia Tachpnoea Central cyanosis Dullness on percussion of affected lobe(s) Bronchial breath sounds Inspiratory crepitations Increased vocal resonance ```
48
What bacteria can cause pneumonia?

49
What treatment is given to pneumonia patients?
Oxygen I.V fluids CPAP Intubation and ventilation
50
What are the potential complications of pneumonia?
