Here’s another table for you.
What do know about these tables?
What does that mean?
It means that you need to make
sure you take these tables
and get a good understanding.
Your minor information
that is in this table,
if you truly understand your pathology,
these tables speak
volumes to you.
You can use these in
microbiology, so on and so forth.
So here, the topic is still acute
bacterial meningitis, okay?
Tell me about glucose in
your cerebrospinal fluid.
High or low?
High or low in the CSF?
Your WBCs, well, granted, WBC would be
elevated in any type of meningitis.
But here, it’s specifically –
What kind of WBC would you
expect to see in bacterial?
Now, based on that, what are the
parameters that we’re looking at here?
We have the predisposing
factors in terms of age.
And then depending, on the age, we’ll talk
about the most common bacterial pathogen.
And then quickly, we’ll take a
look at management commonly
for antimicrobial therapy.
Less than one month,
what are your organisms?
Agalactiae, memorize that.
E. coli, gram-negative organism.
Listeria, at least know
those three organisms
causing acute bacterial meningitis
in a child less than one month.
This keeps changing, but for the
most part, you have ampicillin
being a common denominator plus cefotaxime
or maybe perhaps aminoglycoside.
Now, what’s an interesting point that
the boards love to ask and clinically
that you need to make sure that if you’re
getting questioned by your attending
and you want to make sure that you’re
well-versed with, let’s say, drug interactions,
1 – 23 months in hour getting close to 2 years.
What kind of organisms you are looking at here?
Still streptococcus mainly perhaps.
But this time its pneumonia.
Neisseria is its ugly head here.
And you still have agalactiae
And we have a new comer
And that would be our haemophilus influenzae.
Keep that in mind but I want
to make sure that you are clear.
Step back for one second the
haemophilus influenzae will be the virus
I apologize for putting
this under bacteria but
I like to put this seriously
that you have common organisms
that cause acute meningitis with H.
Here if you are thinking about the
this age group maybe perhaps the vancomycin
And we have a little bit later.
A little bit later meaning what?
The two extreme ages of life.
Very young and very old.
For this row,
very young, very old.
With streptococcus pneumoniae
and there is this species
Once again vancomycin.
And then greater than 50 you should be
thinking about streptococcus pneumoniae
And maybe perhaps your Listeria monocytogenes.
Alright, so we are getting to old once again.
A vancomycin plus ampicillin
And then you have a plus third generation.
So here’s the general overview as to when
you can expect in terms of common pathogens
All of these are all bacterial, okay.
