Flashcards in 37. Pneumonia Deck (31):
1

types of pneumonia

1. lobar
2. brochopneumonia
3. interstitial pneumonia

2

lobar pneumonia - typical organisms

s.pneumonia
legionela
klebsiella

3

Bronchopneumonia - typical organism

S. pneumonia
S.aureus
H.influenza
Klebsiella

4

Interstitial pneumonia is also called

atypical pneumonia

5

interstitial (atypical) pneumonia - typical organisms

1. Viruses (influenza, CMV, RSV, adenovirus)
2. Mycoplasma
3. Legionella
4.Chlamydia

6

MC typical organism for lobar pneumonia

1. viruses (influenza, Cmv, RSV, ademovirus)
2. Mycoplasma
3. Legionella
4.Chlamydia

7

MC typical organism for lobar pneumonia

S pneumonia

8

organism that causes BOTH lobar and bronchopneumonia

Klebsiella
S. pneumonia

9

interstitial (atypical) pneumonia - viruses

1. influenza
2. CMV
3. RSV
4.adenovirus

10

Lobar pneumonia - distribution

entire lobe or entire lung

11

bronchopneumonia - distribution

patchy distribution involving >= 1 lobe

12

interstitial atypical pneumonia

distribution involve > = 1 lobe Diffuse

13

lobar pneumonia - histology

intra -alveolar exudate --> consodilation

14

bronchopneumonia - histology

acute inflammatory infiltrates from bronchioles into adjaccent alveoli

15

interstitial atypical pneumonia- histology

diffuse patchy inflammation localized to interstitial areas at alveolar walls

16

walking pneumonia

interstitial (atypical) pneumonia --> generally follows a more indolent course

17

interstitial atypical pneumonia- typical presentation

relatively mild URI symptoms

18

gross phases of lobar pneumonia (and pathophysiology)

1. congestion (congested vessels and edema)
2. red hepatization (due to exudate, neutrophils and haemorrhage in alveolar)
3. Gray hepatization (degration of red cells in exudate)
4. Resolution

19

Aspiration pneumonia seen in

1. alcoholics
2. comatose patients
3. epileptics

20

aspiration pneumonia - most often due to (organisms)

anaerobic bacteria in oropharynx (bacteroids, peptostreptococcus , fusobacterium)

21

s. pneumonia - pneumonia type

lobar or bronchopulmonary

22

legionella - pneumonia type

lobar or atypical

23

klebsiella - pneumonia type

lobar or bronchopulmonary (or lun abscess)

24

S.aureus pneumonia type

bronchopneumonia (or lung abscess

25

h. influenza

BRONCHOPNEUMONIA

26

• List three bacterial causes of interstitial pneumonia.





Mycoplasma, Legionella, and Chlamydia

27

• Which type of pneumonia is most often caused by viruses?

Interstitial (atypical) pneumonia

28

• List four viruses that commonly cause interstitial pneumonia.

Respiratory syncytial virus, influenza virus, cytomegalovirus, and adenovirus

29

• Interstitial pneumonia characteristically shows diffuse, patchy inflammation that is localized to what areas of the lung?

Interstitial areas at the alveolar walls

30

• The distribution of interstitial pneumonia characteristically involves how many lobes?

At least one, usually more

31

• Which category of pneumonia typically has a less acute presentation?


Interstitial pneumonia (walking pneumonia)
