Flashcards in Neurological Infections - Bacterial Meningitis Deck (25):
1

How are neurological infections classified?

By anatomical location and the microbe causing it

2

What are the ways pathogens can enter into the cranium? (4)

Fractured skull
Along axon
Extension from contiguous infection (ear/nose)
BBB compromised

3

What is bacterial meningitis?

Infection & inflammation of the meninges

4

Is bacterial meningitis life threatening?

Yes

5

What is the etiology of bacterial meningitis?

Bacterium within cranium

6

Which bacterium cause bacterial meningitis? And what age groups do they affect?

Streptococcus pneumonia (affects adults)
Haemophilius influenzae (kids 4-5)
Neisseria meningitidis (youth)

7

What puts people at a predisposition for bacterial meningitis? (3)

Head trauma
Neuro surgery (sc or brain)
Congruent infection

8

What is the patho of bacterial meningitis?

Microbe proliferates and lysis occurs leading to compression due to taking up space

Inflammation occurs & purulent exudate forms on brain and SC leading to compression

9

Are just the meninges affected in bacterial meningitis?

No, the vasculature, ventricles and subarachnoid space is also impacted

10

What are manifestations of bacterial meningitis?

Systemic fever
Headache
Nausea and vomiting
Neck pain (maybe back pain too)
Nuchal rigidity
Usually positive brudzinskis and kernigs sign

11

How is bacterial meningitis?

History and physical/neuro exam
C&S
CSF analysis

12

What is the treatment for bacterial meningitis?

Antibiotics and steroids

13

What do proteins in the CSF indicate?

BBB compromised
Autoimmunity
Inflammation
