Cervical Cancer Screening
 1943 Papanicolaou and Trout published their
monograph on the use of vaginal and cervical cytology
as a screening tool for cervical neoplasm
 The incidence of cervical cancer has been reduced by
50%
 Cervical cancer has dropped from the #2 female
cancer deaths to the 13th
Types of Cervical Cancer
 Squamous cell Approximately 80-90% of cervical cancers
 Adenocarcinoma 10%
 Clear cell cervical cancer
 Mucinous adenocarcinoma
 Adenosquamous
 Glassy cell carcinoma
 Stromal sarcoma
 Sarcoma botryoides
 Leiomyosarcoma
 Lymphoma
 Small cell cervical cancer
 Adenoid cystic carcinoma of the cervix

Most dysplasia regresses
spontaneously in adolescents
 A prospective study of 187 women aged 18-22 years old
found that LSIL had reverted to negative in 61% after 1
year and 91% after 3 years
 Only 3% progressed to CIN 3
 Two smaller studies of adolescent females with biopsy
confirmed CIN 2 showed 65-75% regression after 18
months and 36 months
 ACOG practice bulletin 2009
Estimated Likelihood of Time to LSIL
Regression in Adolescents
 In a study of women 13–22 years of age, there was a 91%
probability of regression of LSIL cases within 36 months.
 The probability of progression to HSIL within this same time
frame was 3%.

How often to screen

 Women aged 30 or older with three consecutive negative
pap smears can be followed every three years
More frequent screening for




HIV infected women
Immunosuppressed women
Women exposed to DES
Women with previously treated CIN2, CIN 3 , or cancer
How often to screen
 Frequency
 Women with HIV should be screened
every 6 months in the first year of
diagnosis, then every year
 Women treated in the past for CIN2, CIN3,
or cancer are at risk for 20 years for
recurrence or persistence, annual
screening
Special Notes
 The frequency of those with same sex partners
 Penetrative sex at an early age
 Same screening in those who have been vaccinated
against HPV ( ACOG press release 11/09)
Pelvic Inflammatory disease in
pregnancy
 A 23 year old P2032 at 8 weeks and 6 /7 days presents to ER
with complaint of nausea, vomiting, and abdominal pain
Past Medical history : NC
Past Surgical history : TAB x 3
Social history : positive marijuana use
Gyn/OB history: new partner, history of Chlamydia, Trich, PID in past, SVD times two
Vitals 37.0 , RR 20, P 65, BP 97/59
PE: moderate distress
Abdomen soft, no rebound or guarding,
Pelvic: Yellow vaginal discharge, cervical motion tenderness
Sonogram: 8 week fetus with fetal HMS
Pelvic Inflammatory disease in
pregnancy

chlamydia, Trich on wet prep
 Hospital course: pt was admitted with diagnosis of PID
in pregnancy, Treated 48 hours with IV Gentamycin
and Clindamycin , po Azithomycin
 Discharge Home with Clindamycin for ten days
Pelvic Inflammatory Disease
 Most of the times multi-organism
 Can range from endometritis to pelvic
abcesses
 300,000 cases per year
 16-20% in Adolescents
 Clinical diagnosis overestimated and
difficult
Pelvic Inflammatory Disease
•Empiric treatment warranted if suspected
because of long term effects if untreated
•Begin treatment if sexually active and
– Uterine tenderness
–Adnexal tenderness
– Cervical motion tenderness (CMT)
Pelvic Inflammatory Disease
 Additional Criteria:
 Temp > 101 F (38.3 C)
 Mucopurulent cervical discharge
 WBC on microscopy
 Increased erythrocyte sedimentation rate
 Increased C-reactive protein
 Positive culture for N. gonorrhea or Chlamydia
Pelvic Inflammatory Disease
 Treat in hospital if:
 Surgical emergency cannot be excluded
 Pregnancy (rare 1: 1000 to 1:25000)
 No initial clinical response
 Does not tolerate PO
 Severe illness
 Tubo-Ovarian abscess

Pelvic Inflammatory Disease
 Pregnancy:
 Multiple reports in the literature (1:1000-1:25000)
 Easily confused with ectopic pregnancy
 Associated with fetal wastage and poor outcomes
 Etiology confusing:

Sperm carrying bacteria?

Infection prior to 12 weeks and membrane apposition?

Reactivation of latent disease?

Hematogenous or Lymphatic spread?
Lara-Torre E et al JRM 2002;47:959-61
Pelvic Inflammatory Disease
 Pregnancy (cont):
 Aggressive antibiotic treatment warranted prior to
uterine evacuation
 Conservative treatment may maintain pregnancy to
term
 Delay in diagnosis because of pregnancy may worsen
outcomes
 Decrease immune response in pregnancy may worsen
presentation and progression
