Abscess, furuncle, and carbuncles require incision and drainage #medmicro – at Manhattan, NY
1
Folliculitis: S. Aureus, Pseudomonas aeruginosa (hot tub), inflammatory/non-infectious. Topical or oral antibiotic #medmicro – at Manhattan, NY
staph scalded skin syndrome: extensive superficial blistering and exfoliation. Toxins mediated. #medmicro – at Manhattan, NY
Mupirocin is a topical anti S. Aureus antibiotic for mild impetigo #medmicro – at Manhattan, NY
Bullous impetigo: toxin producing S. Aureus #medmicro – at Manhattan, NY
Impetigo: honey crusting; at sites of lack of skin integrity; S. aureus and GR A Strep #medmicro – at Manhattan, NY
Complement and coagulation also co tribute to the sepsis response #medmicro – at Manhattan, NY
Pathogenesis of sepsis starts with TLR recognizing PAMPs leading to NF-kB activating genes for pro and anti-inflammatory cytokines #medmicro – at Manhattan, NY
Sepsis and SIRS: start broad antibiotics and do source control of infection #medmicro – at Manhattan, NY
First step of managing SIRS or sepsis is fluids. Second step is antibiotics. Whenever possible get cultures before antibiotics #medmicro – at Manhattan, NY
SIRS: the definition doesn't include low BP as this is a late finding which appears when patient is in severe sepsis #medmicro – at Manhattan, NY
Article of interest: antibiotic use in cattle increased the pevalence of shiga toxin + E. coli CDC wwwnc.cdc.gov/eid/article/22… via @CDCgov
Aminoglycosides: understand concentration dependent (As opposed to time dependent) activity and post-antibiotic effect. #medmicro – at Manhattan, NY
Aminoglycosides:Amikacin broader spectrum than genta and tobramycin. Save amikacin for when multidrug resistance suspected! #medmicro – at Manhattan, NY
Aminoglycosides: protein synthesis inhibitor. Resistance commonly by drug modification. #medmicro – at Manhattan, NY
Aminoglycosides: no PO. Nephrotoxic. Ototoxic. Neuromuscular blockade. #medmicro – at Manhattan, NY
Aminoglycosides: gram negs including pseudomonas . By themselves not active against gram pos, but sometimes synergistic #medmicro – at Manhattan, NY
Stenotrophomonas- multidrug resistant nosocomial pathogen. Trimethoprim sulfamethoxazole drug of choice #medmicro – at Manhattan, NY

Burkholderia cepacia- CF lung infection. Associated with rapid progression of CF #medmicro – at Manhattan, NY
Drugs for pseudomonas: piperacillin-tazobactam, cefepime , carbapenems except ertapenem, aminoglycosides, fluoroquinolones #medmicro – at Manhattan, NY
