Antibiotics on Step 2

[mizzrazmatazz]

Hi all, no matter how many times I've memorized (or tried to memorize) coverage of different antibiotics,it never seems to stick. As I have been doing UW questions, I realize it's important to know SPECIFIC antibiotic treatments for certain diseases.

Any advice on the easiest way to go about doing this???

i'd go with the latter for usmle purposes. knowing the former is good form, but knowing the specific tx's for maybe the top 20 infections is very high-yield.

If I go with the latter, do you think the specific tx's on UW are accurate? It's just that different books have different suggestions for which antibx within a certain group and trying to remember all the different combinations for some reason is really hard for me!

If anyone has a list of the top 20 high yield infections and tx's they want to share, I'd appreciate it!!

Most of the drugs on the exam were the ones you will commonly use, so just know their indications (i.e. Bactrim, Doxycycline, Vancomycin, Pen G, etc....)

this is off the top of my head, but here's some basics as i've learned them...
sinusitis or middle ear infection - amox or amox/clauv. can use azithro or 2nd gen ceph; newer FQ (moxi or levo) for refractory cases.
animal bite - amox/clauv
lyme - doxy; if advanced or cns (except bell's palsy) use ceftriaxone
GC - ceftriaxone
chlamydia - doxy or azithro
PID - doxy+ceftriaxone; i think ofloxacin+metro is also used
cellulitis - diclox or cephalexin if simple
meningitis - complicated. amp+gent for infants, vanc+ceftriaxone for most, vanc+ceftr+amp for elderly
syphilis - PCN
strep throat - PCN
endocarditis - vanc+/-gent empirically
diverticulitis - cipro+metro or amox/clauv
cholecystitis - cipro+metro. probably other acceptable combo's
prostatitis - usually a FQ
UTI - tmp/smz or cipro or nitrofur
whooping cough - macrolides if early

I'm not sure if these are the TOP 20, but there are 20 of 'em, in no particular order:
1 Pseudomonas pneumonia: Ticarcillin/Piperacillin
2 Perioperative prophylaxis: 1st generation Cephalosporin
3 Bacterial Meningitis: 3rd generation Cephalosporin, Vanco, steroids
4 Lyme disease: doxycycline, IV ceftriaxone for complicated cases
5 Prostatitis: Cipro
6 Atypical pneumonia/Community acquired, outpatient: Macrolide
7 “ “ inpatient quinolone
8 Vanco Resistant Enterococcus: Linezolid, quinupristin/dalfopristin
9 Chlamydia: erythromycin or doxycyclin
10 Strep pharyngitis: Penicillin
11 Otitis Media: Amoxicillin
12 Sinusitis: Amoxicillin
13 UTIs uncomplicated: #1 tmp/smx, #2 Nitrofurantoin
14 Pyelonephritis: Quinolone
15 Suspect Listeria meningitis: Ampicillin, 3rd gen ceph, vanco
16 MRSA: Vanco
17 PID: Empiric outpatient = ceph + doxy inpatient = ampicillin, gentamicin + clindamicin
18 Gonorrhea: ceftriaxone
19 Trichomonas: Metronidazole
20 Syphillis: Penicillin

Anybody got a different list or disagree with these?
