1

what are the risks for developing chronic pulmonary infection?

- abnormal host response
- abnormal innate host defence
- repeated insult

2

what does an IgA deficiency do?

- increased risk of acute infections but not chronic infections

3

what is hypogammaglobulineaemia?

- rare, increased risk of acute and chronic infections
- poor host immune response

4

what is CVID?

- most common cause of immunodeficiency, recurrent infection
- specific polysaccharide antibody deficiency

5

give examples of immunosuppressants.

- steroids
- monoclonal antibodies
- chemotherapy

6

what suppresses the activity of cilia?

smoking

7

what are examples of defective innate host defences?

- damaged bronchial mucosa eg malignancy
- abnormal cilia
- abnormal secretions eg cystic fibrosis

8

give example of repeated insult?

- recurrent aspiration eg NG feeding, poor swallow = swallowing into the wrong hole
- indwelling material eg NG tube in the wrong place

9

what is an intrapulmonary abscess?

- indolent presentation
- weight loss common
- lethargy, weakness
- cough/sputum
- high mortality if not treated
-

10

how does pneumonia precede to an abscess?

- flu
- staph pneumonia
- caaviting pneumoina
- abscess

11

when will you see a pharyngeal pouch?

in aspiration pneumonia?

12

what is empyema?

pus in the pleural space

13

how does effusion (water) progress to empyema?

- simple parapneumoinc effusion
- complicated parapneumonic effusion
- empyema

14

what are the gram positive and negative bacteria of empyema?

positive = strep milleri, staph aureus
negative = e.coli, pseudomonas, H. influenzae, kelbsiellae

15

how is empyema diagnosed?

- clinical suspicion
- CXR - look for a D
- USS - ultrasound
- CT

16

how is empyema treated?

- Iv antibiotics = broad spectrum, amoxicillin and metronidazole initially

17

what is bronchiectasis?

- localised, irreversible dilation of the bronchial tree
- involved bronchi are dilated, inflamed and easily collapsible
- airflow obstruction
- impaired clearance of secretion

18

how does bronchiectasis present?

- recurrent chest infections
- recurrent antibiotic prescriptions
- no response to antibiotics
- persistent sputum production
