Q

management o fHPV

A

Podofilox, imiquimod cream or sinecathechins oinment (patient administered )

Cryotherapy with liquid nitrogen, podophyllin or TCA/BCA or surgical removal ( clinican administered)

photodynamic therapy or topical cidofovir.

**condoms should be used until both partners are lesion free and for as long as nine months after the appearance of lesions as subclinical HPV may remain infectious.

Q

Trichomoniasis Assessment

A

STRAWBERRY spots or tiny petechiae on cervix & vaginal walls
severe cases: inflammation
pH is elevated

19
Q

Trichomoniasis diagnosis test

A

WET PREP: visualization of typical one-celled FLAGELLATE trichomonads.
increase WBC
culture is sensitive and highly specific but not routinely performed. this only use when trichomoniasis is suspected but cannot comfirm with microscopic (wet prep)

20
Q

Trichomoniasis management

A

metronidazole (FLAGYL) 2gm PO single dose NO TOPICAL !!!
tinidazole 2gm PO single dose
**not to drink alcohol during abt therapy or will experience abdominal distress, nausea, vomiting, HA. abstinence from alcohol should cont. 24 hours after complete metronidazole tx and 72 hours after tinidazole
sex partner should be treated as well & abstain from sex until treated and asymptomatic.

21
Q

Chlamydia

A

higher in 14-24 y.o, BLACK, multiple partners, and failure to use barrier methods of contraception.
most serious complication –> PID

22
Q

Chlamydia assessment

A

POSTCOIDAL bleeding, MUCOID or PURULENT cervical discharge, urinary frequency, dysuria, lower abdominal pain or dyspareunia.
**BLEEDING result from inflammation and erosion of cervical columnar epithelium **

23
Q

diagnostic testing for chlamydia

A
  • ->urine or swab specimens from endocervix or vagina
  • -> nucleic acid amplification tests (NAATs) PREFERRED technique because they provided the highest sensitivity.
  • -> cell culture
  • ->direct immunofluorescence,
  • ->enzyme immunoassay (EIA)
  • ->nucleic acid hybridization test.
24
Q

management of chlamydia

A

AZITHROMYCIN 1gm single dose

or doxycycline 100mg BID for 7 days

25
what is the TEST OF CURE ?
3-4 weeks after treatment is not necessary unless a woman is pregnant has persistent symtoms or may have reinfection. ***seen in women reinfected by an untreated partner*** **abstain from sex until sexual partner treated and wait 7 days after single dose treatment or until completion of 7 day regiment before resuming sexual activity.
26
Gonorrhea
aerobic gram-negative diplococcus Neisseria gonorrhoeae 2nd most reported bacteria STI 15-24 y.o (71%) BLACK women (common) complications: PID, pelvic abscess or Bartholin's abscess.
27
what is Disseminated gonococcal infections (DGI) ?
untreated gonorrhea (rare) 1st stage: bacteremia with chills fever and skin lesions 2nd stage: acute septic arthritis with effusions : wrists, knees, and ankles.
28
gonorrhea assessment
DYSPAREUNIA, change in vaginal discharge, UNILATERAL labial pain and swelling (Bartholin's gland infection) , or lower abdominal discomfort. menstrual irregularities with longer painful menses -->anal intercourse : profuse purulent anal discharge, rectal pain, and blood in the stool. rectal pain itching fullness, pressure, and pain are also common symptoms. --> viral pharyngitis : red swollen uvula and pustule vesicles on soft palate and tonsils similar to streptococcal infection
29
diagnostic testings for gonorrhea
culture nucleic acid hybridization tests (swabs) NAATs (urine or swab specimens from endocervix or vagina)
30
management for gonorrhea
CEFTRIAXONE IM in single dose plus + AZITHROMYCIN 1gm PO singel dose **all pt should be retested 3 months after tx d/t high rate of reinfection.
31
Pelvic Inflammatory Disease
any combination of endometritis, salpingitis, tubo-ovarian abscess, and pelvic peritonitis. **high risk : ADOLESCENT d/t decrease immunity & increase risk for gonorrhea & chlamydia
32
Pelvic Inflammatory Disease assessment
``` abdominal, pelvic, and low back PAIN abnormal vaginal discharge intermenstrual or postcoital BLEEDING fever N/V urinary frequency ```
33
physical examination of PID
``` adnexal tenderness abdominal tenderness uterine tenderness tenderness with cervical movement pelvic tenderness (bilateral) ```
34
diagnosis of PID
one or more of the following : **cervical motion tenderness **uterine tenderness **adnexal tenderness one or more additional criteria to enhance the specificity of minimum criteria: temp >101 abnormal cervical or vaginal mucopurulent discharge presence of abundant numbers of WBC on saline microscopy of vaginal fluid elevated erythrocyte sedimentation rate elevated C-reactive protein level -documentation of gonorrhea & trachomatis specific dx: endometrial biopsy transvaginal sonography or MRI showing thickened fluid-filled tubs or w/o free pelvic fluid laparoscopic abnormalities
35
treatment for PID
broad spectrum abt, no single regime appears to be superiro to the others. clinical improvement w/in 72 hours if not should be evaluate oral : ceftrizxone IM single dose + Doxycycline 100mg BID for 14 days with or w/o metronidazole BID for 14 days.
36
Syphilis
systemic disease caused by Treponema pallidum, motile spirochete high in Black 30-40 y.o (rather than young adult) complex infection that can lead to serious systemic disease and even death when untreated.
37
primary syphilis
CHANCRE painless papule at the site of inoculation and then erodes to form a nontender, shallow, indurated clean ulcer that is several millimeter to a few centimeter in size REGIONAL LYMPHADENOPATHY 3-90 days infectious routes: sexual vertical & chancre
38
secondary syphilis
chancre may still present SKIN LESIONS (papular rash of soles and palms, patchy alopecia, condylomata lata-wartlike lesion) systemic symptoms: FEVER MALAISE ANOREXIA WT. LOSS, HA, MYALGIAS lymphadenopathy
39
latent/tertiary syphilis
``` cardiovascular syphilis (aortitis) skin lesions (gumma) ```
40
diagnostic testing for syphilis
dark-field examination & direct fluorescent antibody for T.pallidum (DFA-TP) of lesion exudates or tissue will provide a definitive diagnosis of early syphillis. VDRL & RPR are screening tests titer 1:16 =active disease CSF to confirm neurosyphilis
41
management of syphilis
single dose PENICILLIN G is preferred drug for all stages of syphilis .. 3 weeks treatment for latent tertiary or unknown duration syphilis alternative: doxycycline or tetracycline
42
Hepatitis B
bloodborne or body fluids (semen, saliva) affects primarily the liver. it remains asymptomatic in as many as half of persons with infection. s/x arthralgia, fatigue, anorexia, N/V, fever, abdominal pain, CLAY COLORED stool, dark urine and JAUNDICE
43
parameters of HEPATITIS B testing
HBsAG - hepatitis B surface antigen (indicates the patient has acute or chronic HBV infection and can transmit it to others) anti-HBs- Hepatitis B surface antibody (indicates pt. has immunity resulting from vaccination or previous infections) anti-HBc- total hepatitis B core antibody (indicates the patient has previous or ongoing infection) IgM anti-HBc- IgM antibody to hepatitis B core antigen (indicates pts has had an acute infection within the past 6 months)
44
management hepatitis B
Vaccination for all individual definite exposure to hepatitis B should be given HEPATITIS B IMMUNOGLOBULIN IM single dose asap and preferably w/in 24 hours after exposure. chronic HBV should be referred to specialist
