Howell 2 Flashcards
what organisms cause the purpura rash of meningitis
-N. Meningiditis (MC)
-Strep. Pneumoniae
H. Influenzae
the neurologic complications that may occur if this patient’s ICP is permitted to rise?
Seizures
Focal Neurologic Deficits
Papilledema
meningitis labs
CBC w/diff, CMP, Coag’s, Blood Cx’s x 2
when to CT meningitis before LP
Immunocompromised state
History of CNS disease (mass lesion, stroke, or focal infection)
New onset seizure (within one week of presentation)
Papilledema
Abnormal level of consciousness
Focal neurologic deficit
What does Rifampin protect against?
Meningicoccal
H. Influenzae
How are other organisms tx’d (prophylactically)?
There is no targeted tx
normal ct in meningitis… what do you do
you LP!!
LP what position
lateral recumbent position
meningitis tx
Dexamethasone (+/-), Vancomycin and Rocephin
What is important about the dexamethasone and the abx?
Give the Dexamethasone First!
Or at least the same time as the abx
symptoms that differentiate meningitis and encephalitis
AMS
focal deficits
most likely source of encephalitis in healthy pt
HSV
most likely source of encephalitis in unhealthy pt
VZV and CMV
What virus typically manifests with challenges in swallowing and hydrophobia?
Rabies virus
Why when considering Encephalitis do you concern yourself with the history and labs?
disttinguse acute arboviral encephalitides as the other acute viral encephalitides, especially HSV encephalitis (HSE) and varicella-zoster encephalitis
normal CSF
Pressure (mmH2O) Appearance Protein (mg/dL) Glucose (mg/dL) WBC
P: 50-200
A: Clear, colorless
P: 10-50
G: 50-80
<5 – all mononuclear
bacterial meningitis LP findings
cloudy (torpid grey)
increased protein and decreased glucose
most common bacterial etiology of community-acquired meningitis in adults of all ages
Streptococcus pneumonia
encapsulated organisms
Streptococcus pneumoniae N. meningitidis H. influenzae Group B streptococcus E.Coli Klebsiella Salmonella
this is important bc no spleen = increased
organism to suspect in pts with meningitis following vp shunt
gram - bacilli
What are the most common cause of neonatal meningitis?
Group B streptococcus andEscherichia coli
Where is the MC source of this for the baby, when less than 6 days?
Vertical Transmission
Maternal transmission, MC during delivery. Screening after: 35-37 weeks and providing abx during delivery.
What is the MC cause of disease in neonate after 7 days?
Nosocomial
age/organism
>1 month and < 3 month
Group B strep
age/organism
>3 month and < 3 years
> 3 years and 10 years
> 10 yrs and < 19 years
Group B strep
N. Meniningiditis
