Dx: ELISA will be negative! Must do PCR to check for viral load!
Tx: ARV 2+1

AZT = Zidovudine
CD4 <200 = at risk for….
Prophylaxis?
PCP Pneumonia!
Bactrim(TMP-SMX)>Dapsone>Atorvaqovne

Pt w/fever and HA, when can you not do a lumbar puncture?
FAILS: FND, AMS, Immunosuppressive, Lesion, Seizures
Pt w/fever HA and FAILS+ what test do you do?
Go ahead and give ABX(vanc,ceftriax,steroids +/- amp) and do CT scan
Patient w/suspected brain inflammation that is FAILS+ but has a normal CT, next step?
Lumbar punction
Pt suspected brain inflammation, FAILS+, ABx started, CT shows somthing…next step?
Treat for toxo = Pyrimethamine + sulfadiazine + leuvocovorin
After you treat a patient for toxo of the brain what do you do?
Rescan brain w/CT! If shit still there do Bx to rule out infection vs cancer
Brain inflammation: pt w/lymphocytes on lumbar puncture tx?
Assume HSV & tx w/acyclovir + do HSV PCR if - just supportive care.
Tx of typical bacterial meningitis
Vanco + ceftriax + steroids +/- ampicillin(only if immuno comp)

Sx for Lyme encephalitis + tx?
Targetoid rash w/arthalgias, arrhythmias. + travel to CT, +/- tick
Tx: ceftriaxone(same as RMSF)
Sx for cryptococcal encephalitis + tx?
AIDs pt w/fever + HA.»_space;20 cm H2O opening + Crypto Ag»_space;Indian ink
Tx: amphotericin
Sx for TB encephalitis + tx?
Night sweats, weight loss, hemoptysis, meningitis, homeless, prison, endemic areas
Tx: RIPE
2 most common organisms that cause cellulitis?
Staph(likes to burrow and cause abscesses) & GAS
Sx of cellulitis + Dx + tx?
Hot, red, tender area of skin + known entry point. DO NOT CULTURE!
Tx: mark boundries so you can note if recedes after d1 of abx & give clindamycin or Bactrim for staph or 1st gen cephalosporin for GAS
If toxic: vanc, Linz, clinda
+ bone pain +probe to bone + refractory cellulitis
Dx?
Tx?
F/u?
Dx: 1. Xray(+@2wks) 2. MRI 3. Bone Scan, 4. BIOPSY = best
Tx: DEBRIDMENT + 4-6wks Vanc + Pip/tazo
F/U: ESR, CRP once drop your okay
