swelling and warmth
staph aureus
diagnosis FNA
describe infectious tenosynovitis
infection of synovial sheets around tendons
usually finger
held in semiflexed position
what is toxic shock syndrome
tampon in too long fever, macular rash staph aureus in normally sterile sites remove tampo IV fluids antibitoics
