OBGYN Precision & Pearls #2 Flashcards
What is trophoblastic disease (molar pregnancy)?
Also, explain what complete vs partial means
Pregnancy due to nonviable fertilized egg implanting, leading to abnormal placental development
-Complete (Diploid 46XX): all paternal chromosomes and no fetal tissue
Partial (Triploid 69XXX or XXY): egg fertilized by 2 sperm. Fetal tissue present but not viable
A molar pregnancy has a higher risk of developing into _______ and some risk factors for a molar pregnancy include…..
Choriocarcinoma
Prior molar pregnancy and extremes of age (<20 and > 35)
What are some symptoms of a molar pregnancy?
-Painless vaginal bleeding
-Uterine size/date discrepancies (larger than expected)
-Preeclampsia before 20 weeks
-Hyperemesis gravidarum earlier than usual
-Choriocarcinoma (METS MC to lungs)
What labs are done for a molar pregnancy and what do they normally show?
-Beta HCG very high (>100,000)
-Alpha fetoprotein very low
-Pelvic US: snowstorm or cluster of grapes (no fetal parts or heart tones)
Treatment for a molar pregnancy
Surgical uterine evacuation (suction curettage). Followed weekly until Beta HCG levels fall to undetectable level.
Chest XR to check for METS for choriocarcinoma. If present, chemo/radiation.
Risks for developing gestational diabetes, fetal risks of diabetes, and maternal complications of gestational diabetes.
Risks for developing: Obesity, > 25 years old, African American race, Family history, birthing baby > 4000g, multiple gestations
Fetal complications: Macrosomia (MC), preterm labor, neonatal hypoglycemia, neonatal hypocalcemia
Maternal complications: 50% chance of developing DMII after pregnancy
How long postpartum should the mother be screened for diabetes?
Screen mom 6 weeks postpartum for DM and then yearly afterwards
Screening for gestational diabetes (2 step)
What is the GOLD STANDARD diagnostic?
Step 1: 50g 1 hr glucose challenge test: If 130-140g, do 3 hour test
Step 2: 100g 3 hr glucose challenge test: Positive if 2 or more of the following: (>95 after fasting, >180 at 1 hour, >155 at 2 hours, >140 at 3 hours)
Testing is done at 24-28 weeks
3 hour glucose challenge is the GOLD STANDARD
What is the treatment for gestational diabetes
1) Lifestyle modifications: diet and exercise/walking
2) Insulin (1st DOC)
3) Glyburide and Metformin also safe in pregnancy
What is another recommendation for gestational diabetes and delivery times?
Daily fingersticks overnight and after each meal
Labor induction at 38 weeks if uncontrolled/macrosomia.
Labor induction at 40 weeks if controlled/no macrosomia
Recommend C-section if diabetic
What is normal morning sickness considered?
Nausea and vomiting up until 16 weeks
What is hyperemesis gravidarum?
Severe, excessive morning sickness associated with weight loss and electrolyte imbalance. Persists > 16 weeks
Treatment for Hyperemesis gravidarum
-PO or IV Fluids
-Bland diet: BRAT (Bananas, Rice, Applesauce, Toast)
-Pyridoxine (B6) + Doxylamine
What is chronic preexisting hypertension and what is the treatment?
Hypertension before 20 weeks gestation
Treatment: Labetolol, Nifedipine, Methyldopa are first line agents
What two anti-hypertensive classes should NOT be used in treatment of gestational hypertension?
ACE and ARB
On the other hand, what is transitional hypertension? What is the treatment for this?
New onset hypertension after 20 weeks gestation with NO proteinuria or end organ dysfunction
Nifedipine, Labetolol, Methyldopa
When does transitional hypertension normally resolve?
12 weeks postpartum
For pregnancy HTN, what should you do to monitor the patient?
Check BP
Ask about symptoms of HTN such as headache, visual symptoms.
Check for fetal growth restriction.
Look for edema.
Increased DTR’s.
What is preeclampsia? What does it mean to have MILD vs SEVERE?
New onset hypertension after 20 weeks gestation with proteinuria and end organ dysfunction.
MILD: >140/90, proteinuria > 300mg/24 hours (or dipstick 1+ or 2+)
SEVERE: >160/110, proteinuria >5g (or dipstick 3+)
What are some end-organ symptoms of preeclampsia?
Headache, flashes, blurry vision, RUQ pain, peripheral edema
-Progressive renal insufficiency: oliguria
-Thrombocytopenia
-HELLP Syndrome: Hemolytic anemia, elevated liver enzymes, low platelets
Treatment for preeclampsia (if >37 weeks vs < 37 weeks)
-If 37 or more weeks: prompt delivery
-If < 37 weeks, expectant management (daily weights, BP monitoring, dipsticks, bed rest, steroids for lung maturity)
-Give IV Mag Sulfate to prevent seizures
What is eclampsia? What is the treatment?
Preeclampsia + onset of tonic-clonic seizures, or coma
-Also can have hyperreflexia
Treatment: ABCD’s first, IV Mag Sulfate for seizures, Lorazepam is 2nd line for refractory.
Delivery of fetus once patient stabilized.
BP meds: Hydralazine or Labetolol IV
How long postpartum can preeclampsia continue?
6 weeks postpartum
Postpartum depression can occur in what time frame? What is the treatment?
2 weeks - 12 months postpartum
SSRI + CBT
MC type of vaginal cancer. What is the MC site of this cancer?
Squamous cell carcinoma
Posterior wall of the upper 1/3 of the vagina
Symptoms of vaginal cancer? What is the definitive diagnostic and treatment?
Abnormal vaginal bleeding (postcoital)
Biopsy is definitive
Surgical excision or radiation therapy is treatment
MC type of vulvar cancer? MC risk factor for this cancer? Symptoms? MC location?
Squamous cell carcinoma
HPV 16 and 18, DES exposure, 50 years old
Vulvar pruritis, bleeding, pain
Labia Majoris
What is seen on exam in a patient with vulvar cancer?
Red or white ulcerative or crusted lesion
