Flashcards in GU micro bugs Deck (45):
1

caused by HPV 6 and 11

condylomata acuminata = genital warts (STD)

2

koilocytosis: perinuclear cystoplasmic clearing

HPV infection

3

women initially asymptomatic: cervicitis, urethritis → PID (do have symptoms)
men: urethritis, dysuria, mucopurulent discharge, epidiymitis (unilateral pain, swelling of testicle)
disseminated infection: gonococcal arthritis

gonorrhea: N. gonorrhoeae

4

joint pain in young, sexually active patient

N. gonorrheae

5

if infected with N. gonorrheae, this assume infected with

C. trachomatis D-K

6

most common bacterial STI

C. trachomatis D-K

7

most common viral STI

condyloma acuminata

8

women asymptomatic: cervicitis, urethritis, dysuria → PID
men: urethritis, epididymitis, prostatitis
reactive arthritis
conjunctivitis: infected genital secretions to the eye

C. trachomatis D-K

9

urethritis
arthritis
uveitis

reactive arthritis: most common cause is C. trachomatis D-K

10

lymphogranloma venerum

C. trachomatis L1-L3 (STD)

11

PAINLESS genital ulcer
extends into lymphatics → PAINFUL inguinal LAD (buboes - can rupture)

lymphogranloma venerum: C. trachomatis L1-L3 (STD)

12

STDs that can cause genital ulcers

lymphogranuloma venereum: C. trachomatis L1-L3
HSV (1: cold sores, 2: genital herpes)
chancroid
syphilis

13

PAINFUL vesicles on erythemetous base → erode → become shallow ulcers
if 1° infection: fever, headache, malaise, myalgia

HSV (STD)

14

PAINFUL genital ulcer
PAINFUL inguinal LAD

haemophilus ducreyi: chancroid (STD)

15

PAINFUL ulcers with distinct borders
purulent exudate from ulcers

haemophilus ducreyi: chancroid (STD)

16

G- rod that causes STD
"school of fish" appearance

haemophilus ducreyi: chancroid (STD)

17

chancre: PAINLESS genital ulcer (edges raised)

treponema pallidum: 1° syphilis (STD)

18

spirochete that causes STD

treponema pallidum: syphilis (STD)

19

systemic infection: fever, headache, malaise, general LAD
RASH
CONDYLOMA LATA

treponema pallidum: 2° syphilis (STD)

20

Neurosyphilis: tabes dorsalis, argyll robertson pupil
CV syphilis: aortitis
Gummatous syphilis: gummas

treponema pallidum: 3° syphilis (STD)

21

erythematous macules → become papules
PALMS + SOLES

rash of 2° syphillis

22

flat, smooth, moist white lesions near genitals from STD

condyloma lata: 2° syphilis (STD)

23

granulomatous lesion on skin from STD

gumma: 3° syphilis (STD)

24

PAINLESS ulcers from STD

lymphogranuloma venereum: C. trachomatis L1-L3
syphilis chancre: T. pallidum

25

PAINFUL ulcers from STD

chancroid: H. ducreyi
HSV

26

strawberry cervix

trichomonas vaginalis

27

ascending infection of upper reproductive tract:
uterus: endometritis
fallopian tube: salpingitis, hydrosalpinx (if tubes blocked with fluid), tubo-ovarian abscess
ovary: oophoritis
fitz-hugh curtis syndrome: infection of liver capsule - "violin string" adhesions

PID

28

common organisms that can cause PID

infection gets past cervical mucous barrier → allow normal vaginal flora in (polymicrobial)
N. gonorrhoeae
C. trachomatis

29

pelvic pain, low ab pain
cervical motion tenderness "chandelier sign"
mucopurulent cervical discharge
complications: infertility, chronic pelvic pain, ECTOPIC PREGNANCY

PID

30

treatment for PID

broad spectrum antibiotics

31

common cause of UTIs

G- rods: E. coli (fecal matter)

32

populations prone to UTIs

women
children: vesicoureteral reflux
urinary tract obstruction (BPH, tumors, stones
indwelling catheter
bladder dysfunction/stasis: neurogenic bladder in diabetes, spinal cord injury
pregnancy
immunosuppresion

33

dysuria
frequency
urgency
suprapubic pain
hematuria

cysitis

34

cystitis symptoms +
fever/chills
N/V
flank pain
CVA tenderness

pyelonephritis

35

diagnosis of cystitis/pyelonephritis

confirmed by UA

36

common causes of UTI

E.coli -80%
Proteus mirabilis
Klebsiella pneumoniae
Enterobacter
G+: staph saprophyticus (2nd most common cause of UTI in young, sexually active women)
hospitalized:
serratia marcesens
pseudomonas

37

G- rod
"swarming" motility in culture
produces urease: struvite stones (fill in renal pelvis and extend into calices "staghorn calculus"

proteus mirabilis

38

function of urease

hydrolyzes urea → ammonia →↑ pH of urine (more alkaline) → struvite stones (magnesium ammonium phosphate)

39

most common type of nosocomial infection

UTI from indwelling catheter

40

catheter-associated UTI in hospital

E.coli (most common)
G- rods
pseudomonas
candida

41

ventilator-associated pneumonia

pseudomonas
s. aureus

42

central line (venous catheter) infections

staphylococcus epidermidis sepsis

43

surgical wound/decubitus ulcers in hospital

s. aureus

44

parenteral nutrition (IV)

candida sepsis

45
