  8. Pyelonephritis (from non-tx UTI)
    • Sx: chills, fever, n/v, flank pain, dehydration, <low creatinine clearance, marked bacteremia in urine culture, WBC casts.
    • Tx: hospital, IV ABX, cath if needed, supportive therapy for comfort, follow-up urine cultures.
    • PG complic: <BW baby, preterm labor
  9. Vulvovaginal Candidiasis
    • Yeast infection
    • Cause: Candida Albicans

    • PG complic: NB thrush if born vaginally
  10. Bacterial vaginosis
    • Gardnerella vaginalis
    • Sx: thin yellow-gray fishy discharge, Clue cells on wet-mount slide
    • Tx: Metronidazole (Flagyl), clindamycin
    • PG complic: PROM - not teratogenic
