inorganic exposure
organic exposure
smoking
rare forms
idiopathic

Question 5

Answer 6

pleural diseases including pleural effusion, pleuritis and pleural plaques

Question 8

what is the most common interstitial lung disease

Answer 8

idiopathic pulmonary fibrosis

Question 9

Mesothelioma

Answer 9

aggressive cancer

Question 10

3 investigations for restrictive lung disease

Answer 10

ABG
CXR
Spirometry

Question 11

how is a diagnosis of idiopathic pulmonary fibrosis achieved

Answer 11

using a multi-disciplinary team

Question 12

chest wall managements for restrictive lung disease 4

Answer 12

obesity = weight loss
kyphoscoliosis = surgery
oxygen therapy
physiotherapy

Question 13

neuromuscular managements for restrictive lung disease 2

Answer 13

oxygen therapy
physiotherapy

Question 14

interstitial lung disease managements for restrictive lung disease 3

Answer 14

oxygen therapy
antibiotic agents
lung transplantation

Question 15

defences in resp system 3

Answer 15

mucous + cilia
dust cells in alveolar
type 1 pneumocytes

Question 16

3 mechs by which resp defences can be comprimised

Answer 16

defective mucous clearance
dysfunctional cilia
lack of immune response

Question 17

common causes of lung inflammation 6

Answer 17

infection
environmental pollutants
allergens
autoimmune
smoking
occupational exposure

Question 18

pulmonary inflammation mech 3

Answer 18

detection of pathogens through PRRs initiating inflammation

Macrophages and dendritic cells respond to PAMPs by releasing cytokines

Cytokines attract other immune cells and cause vasodilation

Question 19

3 steps in pulmonary inflammation resolution

Answer 19

removal of irritant

apoptosis of immune cells

proliferation of type 2 pneumocytes to restore structural integrity to alveoli

Question 20

granuloma formation in chronic pulmonary formation

Answer 20

macrophages differentiate into epithelioid cells forming a compact cluster around the irritant

remain in the tissue disrupting normal structure and function and continually release inflammatory mediators causing damage

Question 21

consequences of chronic pulmonary inflammation 3

Answer 21

scarring
fibrosis
granuloma formation

Question 22

pharyngitis (def, aetiology -2, management -2, complications - 3)

Answer 22

Def: inflammation of pharynx

Aet: Mostly viral, 1/3 bacterial

Management: Antibiotics, tonsillectomy if severe

Complications scarlet fever, rheumatic fever, glomerularnephritis

Question 23

Otitis media (def, aetiology -2, management -2, complications - 2)

Answer 23

Def: presence of fluid in middle ear w inflammation

Aet: viral/bacterial

Management: analgesia and antibiotics

Complications OME and LOME

Question 24

sinusitis (def, aetiology -1, management -3)

Answer 24

Def: inflammation of paranasal sinuses

Aet: Mainly viral

Management: analgesia, decongestants and antibiotics

Question 25

Epiglottitis (def, diagnosis-2, management -2, complications - 1

Answer 25

Def: cellulitis of epiglottis and surrounding tissues

Diagnosis: inspection and lateral neck x-ray

Management: securing airway and antibiotic therapy

Complication: life threatening airway obstruction

less common
fast progression

Question 28

2 types of NSCLC

Answer 28

adenoma
squamous cell carinoma

Question 29

TNM classification (def and criteria)

Answer 29

Def: indicates cancer severity, guiding treatment and prognosis

T= characteristics of primary tumour
N = number of lymph nodes affected
M = metastasis

Question 30

Invetsigations in cancer (3 broad groups)

Answer 30

Blood test
Imaging: CXR, chest CT, PET
Biopsy:
BRonchoscopy, pleural aspirate, CT guided biopsy

Question 31

key investigation in lung cancer diagnosis

Answer 31

CT chest

Question 32

resp mech in quiet inspiration and expiration

Answer 32

quiet inspiration: diaphragm contracts external intercostals contract

quiet expiration: diaphragm relaxes and external intercostals relax

Question 33

resp mech in forced inspiration and expiration

Answer 33

inspiration: accessory muscles contraction
expiration: abdominal muscle and intercostals contracting

Question 34

role of the resp group 2
