Women's Health Final Exam
Management of LSIL
-A result of LSIL is a good indicator of HPV infection, recent metaanalysis showed prevalence of 76.6%.1 -Prevalence of CIN 2 or greater found at initial colposcopy is 12 - 16%. -Data from ALTS show the risk of CIN 2,3 is the same in women with LSIL and with ASC-US who are positive for HR HPV, and should be managed in the same way except in special populations. -In the current guideline management of this result is heavily dependent on age
Colposcopy
-Colposcopy is a confirmatory, diagnostic (not screening) examination -Clean cervix with saline, note any visible lesions, leukoplakia -Generous and repeated application3-5% Acetic acid. Squamous cells with relatively large or dense nuclei reflect light and turn white. Blood vessels and columnar cells become easier to see. Better differentiation of the transformation zone. -Areas of white epithelium are examined for abnornaml vascular patterns, such as punctuation, mosaicism, or atypical vessels
Indications for intrapartum transfer
-Malpresentation: breech, transverse lie identified during labor -Preeclampsia -Chorioamnionnitis -Fetal intolerance of labor when birth is not imminent or in presence of meconium -Need for pharmacologic augmentation of labor -Signs of placental abruption or unexplained increased vaginal bleeding -Cord prolapse -Management of lacerations beyond the expertise of the attending midwife -Postpartum hemorrhage unresponsive to initial treatments -Retained placenta -Unexplained vaginal bleeding -Uterine rupture, uterine inversion -Unstable health status of newborn
Current pregnancy contraindications
-PTL or PPROM -Essential or gestational hypertension -Fetal anomalies requiring immediate management -Fetal growth restriction <5th percentile -GDM requiring pharmacologic management -Malpresentation: breech, transverse lie -Need for pharmacologic induction of labor -Postterm pregnancy more than 41 6/7 weeks -Multiple gestation -Oligohydramnios, polyhydramnios -Placenta previa in the third trimester -Placental abruption -Preeclampsia -Rh isoimmunization
Management of ASC-H
-Prevalence of CIN 2,3 is higher in women this result than those with ASCUS. 24-94% with this result will have HSIL compared with on 5-17% of women w/ASCUS. -ASC-H is consider equivocal HSIL until colposcopy suggests otherwise (in women of any age).
What are the goals of pap screening?
-Prevent morbidity and mortality from cervical cancer -Prevent overzealous management of lesions that most likely will regress or disappear and for which the risks of management outweigh the benefits
Prior OB contraindications to out-of-hospital birth
-Previous stillbirth or neonatal death related to intrapartum event -Severe postpartum hemorrhage -Prior cesarean birth -Shoulder dystocia with resulting injury
Management of atypical glandular cells
-Relatively uncommon result, reporting rate only 0.4%. -Though occurs rarely, when found it is commonly associated with significant underlying neoplastic conditions including adenocarcinomas of cervix, endometrium, ovary, and fallopian tube. -Because of the wide spectrum of neoplasias possible and the low sensitivity of individual testing modalities, multiple approaches are needed. -Colposcopy with ECC is recommended for all women with AGC as initial treatment except for those with atypical endometrial cells. Those women should be evaluated first with Endometrial biopsy and ECC. Endometrial bx is also done in all women over 35 and women younger than 35 with unexplained bleeding or chronic anovulation.
What are some PMH contraindications for out-of-hospital birth?
-Serious medical conditions, including: cardiac disease, epilepsy, thromboembolic disease, hemoglobinopathy, renal disease, IDDM -Infections, including: hepatitis, HIV, HSV, syphilis, TB -Psychiatric conditions requiring hospital management -Substance abuse/dependence
Management of HSIL
-This finding carries a high risk for significant cervical disease. A single colposcopy will reveal CIN2 or greater in 53-66% of women. CIN 2 or greater is found in 84-97% of women evaluated with excisional procedure. -As colposcopy can miss a significant number of lesions, most women with this result will have an excisional procedure at some point. -As there is considerable risk for CIN 2 or greater, triage with repeat cytology of HPV reflex is never acceptable (in women of any age).
Management of ASC-US
-This finding of ASC is least reproducible of all results, and prevalence of invasive cancer in women with ASC is very low (0.1-0.2%). -In the current algorithms the management of this is heavily dependent on age. -Reflex testing (HPV testing) eliminates need for women to return the office, assures women they do not have significant lesions, and spares 40-60% of women from colposcopy. Reflex testing or screening is avoided in women under 25. If reflex testing shows no HPV, we can screen again in 3 years. Otherwise repeat in 12 months.

If hemoglobin <10.5: 1. Start on Fe, folic acid, and multi-vit supp 2. Counsel on Fe rich foods 3. Reticulocyte count in 2-3 weeks after woman has begun taking Fe. Retic count should increase, since body is responding to Fe
Why do we screen for HPV in older women?
In older women the prevalence of HPV decreases so a positive test is more likely to represent a persistent infection. Additionally, women with a negative HPV test are at even lower risk of having future CIN 3 than women who have a normal pap smear (better negative predictive value).

Can HPV become latent?
Lots of evidence shows many people go to state where HPV appears to be fully cleared - sensitive DNA testing is negative Best answer: we cannot be sure if an infection is new or reactivated - new infections are common, especially in young women; but reactivated infections also seem to occur - particularly in older and immune-comprised patients.

What are we really concerned about if we see it?
Persistent oncogenic HPV infection, CIN 3, CIN 2 in older women, persistent CIN 2/3 in adolescents and younger women
Cryotherapy
Probe against the cervix. Cells damaged by freezing are shed over the next month in a heavy watery discharge. Cryo simple and inexpensive. Cervix often heals with the SCJ inside the canal of the cervix - can make future evaluation more difficult. Cryo acceptable treatment for small, completely visualized areas of dysplasia, but has a high failure rate for treating large areas of dysplasia and dysplasia that extends into the cervical canal. Failure rate is higher.
What factors influence normal hemoglobin levels?
Race: black women have lower hemoglobin Smokers: higher lower limits of hemoglobin Living in high altitudes Increase in maternal plasma volume causing dilutional anemia
Histology
Refers to interpretation of tissue samples obtained from colposcopy guided biopsy.
LEEP
Replaced previously used cone technique. Both diagnosis and treatment. Fine wire loop with electrical energy to remove the abnormal area of the cervix, which is sent for biopsy. When indicated, may be an excellent treatment method, but should be used only for lesions with malignant potential. Has implications for outcomes in future pregnancies.
Cervical scaring and stenosis
Risk correlates with size of excision and also menopausal status. Stenotic cervix can interfere with future visualization of T-zone and increase difficulty of office procedures (e.g. endo bx, IUC insertion, IUI) - Not well studied.
What are consequences of inadequate weight gain?
SGA, PTB, perinatal mortality, failure to initiate breastfeeding
What kind of carrier screen should be done on all women?

What is a genetic cause of normoblastic anemia?
Thalassemia
Squamocolumnar Junction
The cervix is covered by both columnar and squamous epithelium. The SCJ, where these two meet, is the most important cytologic and colposcopic landmark, as this is where over 90% of lower genital tract neoplasia arises.
What should be done with initial testing for someone with anemia?
The initial evaluation of a pregnant person with moderate anemia should include measurements of hemoglobin, hematocrit, and red cell indices; careful examination of a peripheral blood smear; a sickle-cell preparation if the person is of African origin; and measurement of serum iron or ferritin levels, or both.
Nuchal translucency
Ultrasound at 11-14 weeks that tests for trisomy 18, 21, and cardiac issues. Usually combined with 1st trimester traditional serum markers.
What is recommended weight gain?
Underweight: 28-40 Normal weight: 25-35 Overweight: 15-25 Obese: 11-20
Cytology
We look at cytology because the cells at the surface are a marker of the tissue underneath.
What is the current opinion on whether or not low grade lesions will develop into cancerous lesions?
With the discovery that most CIN1 and CIN2 lesions regress or persist unchanged, the question has been raised as to whether high-grade CIN might be a process that develops concurrently with low-grade CIN. This theory is supported by the fact that CIN3 can develop without a detectable preceding low-grade CIN lesion, and high-grade CIN is almost always found closer to the SCJ than concomitant low-grade lesions. Schiffman, et al. reported that both CIN1 and CIN2,3 lesions developed within the same time frame in a large group of women who turned HPV positive and were followed for 4 years. Currently, most experts believe CIN1 has minimal potential for progression to cancer and simply reflects underlying HPV infection, while CIN2,3 is of indeterminate malignant potential. CIN3 is considered a true cancer precursor.
