Q

if patient is pregnant and has mitral stenosis with afib (from rheumatic heart disease) and was on warfarin, what do you do with her anticoagulation now that she’s pregnant?

A

keep anticoagulation because mitral stenosis and afib is high risk for thrombosis.

AC of choice: low molecular weight heparin until final few weeks of pregnancy and then can be transitioned to unfractionated heparin (for easier reversibility)

Q

why do we prefer low molecular weight heparin instead of unfractionated heparin in pregnancy?

A

both can be used but we reserve subcutaneous unfractionated heparin q12h for anticoagulation with severe renal insufficiency (CrCl <30)

try to use LMW heparin due to lower risk of HIT.

This is where there’s painful menses rather than amenorrhea and they have some glandular tissue growing in the uterine wall.

32
Q

tubal sterilization (bilateral tubal ligation) failure rate?

A

effective form of permanent contraception but failure rates are as much as 36/1000 procedures.

33
Q

endometrial cancer presentation

abnormal uterine bleeding in premenopausal pts with chronic unopposed estrogen exposure (anovulation, obesity, PCOS)

34
Q

signs of early pregnancy

A

fatigue, weight gain, secondary amenorrhea and uterine enlargement.

35
Q

secondary amenorrhea

A

prevously had periods and now doesn’t have them

>3 months in previously regular cycles

or >6 months in previous irregular cycles.

36
Q

Chart with list of normal pregnancy lab values and why this happens

A
37
Q

when do maternal physiological changes in pregnancy begin?

A

4 weeks of gestation

38
Q

Common changes in lab values due to pregnancy:

Hgb

WBC

ESR/CRP

Alkaline phosphatase

A

Hgb: becomes anemic due to dilution from expanded plasma volume

WBC: elevated due to increased neutrophil demargination

ESR/CRP: elevated due to stimulation of liver synthetic function by estrogen and progesterone

Alkaline phosphatase: elevated made by placenta often moderately elevated in late pregnancy

39
Q

What lab values do not change with pregnancy and suggest possible pathology?

A

AST/ALT do not hcange and so elevations may be signs of hepatobiliary dx

Hormonal changes from pregnancy also decrease gallbladder contractility and increase biliary cholesterol concentration promoting gallstone formation. This can lead to cholelithiasis and biliary cholic.

40
Q

how to treat pregnant pts who have a bout of biliary cholic (RUQ pain) from symptomatic cholecystitis

A

if isolated episode of biliary colic can respond to supportive care and pain control and low fat diet.

41
Q

thrombocytopenia

elevated Cr

elevated transasminases

Pulm edema

visual or cerebral symptoms

44
Q

Management of Pre eclampsia

A

Without severe features: delivery at >37 weeks

With severe features delivery at >34 weeks

Magnesium sulfate for seizure prophylaxis

antihypertensives.

45
Q

when do you start to see preeclampsia start (in pregnancy gestation period)

A

can start after 20 weeks.

commonly manifests in third trimester

can occur at delivery and up to 6 weeks post partum and most cases can develop 48 hrs of delivery

46
Q

most common features of preeclampsia during pregnancy:

A

headache, epigastric or RUQ pain and visual changes.

47
Q

Most common symptoms post partum of pre eclampsia

A

pulmonary edema

likely from pre eclampsia induced renal changes (proteinuria and exacerbating physiological post partum fluid shifts.

other causes of post partum changes are capillary leak, left heart failure and iatrogenic volume overload.

48
Q

for someone who has postpartum pre eclampsia with pulmonary edema what do you do?

A

blood pressure control, magnesium sulfate for seizure prophylaxis

then fluid restrict and provide oxygen support and diuretics.

49
Q

amniotic fluid embolism presentation and characteristic clues are:

A

acute onset of dyspnea, hypotension (cardiogenic shock) and DIC with bleeding and bruising.

50
Q

peripartum cardiomyopathy presentation

A

dyspnea, cough, pedal edema, HTN and see this in 3rd trimester and postpartum period

would see JVD

DON’T see proteinuria.

51
Q

Gestational thrombocytopenia is a

A

benign self limited condition that happens in 5-7% of pregnancies.

Most cases are late in gestation (usually at delivery) but can arise in 1st trimester. IT is seen incidentally and not associated with any bruising, bleeding or physical exam abnormalities or seen with neonatal thrombocytopenia.

52
Q

What are the platelet counts seen in gestational thrombocytopenia?

A

around 100K -150K.

should continue normal prenatal care and delivery management. NO further testing or treatment is needed.

Platelets should normalize within 6 weeks of delivery.

Thrombocytopenia<80K should prompt you to look for alternate diagnosisi

53
Q

differential diagnosis for gestational thrombocytopenia?

A

immune mediated thrombocytopenia. ITP is diagnosis of exclusion and distinguish between gestational thrombocytoepnia and mild ITP (plt>100K) in pregnancy

do not use antiplatelet antibody testing for suspected ITP work up because doesn’t beck it very well.

54
Q

What vaccines are recommended in pregnancy

which ones are contraindicated?

A
55
Q

Tdap administration during pregnancy schedule is this:

why is it important to give Tdap every pregnancy

A

pertussis in US is increased due to waning immunity and infants <3 months can get it and it has high rates or morbidity and mortality.

Thus it’s needed for every pregnancy

56
Q

who else should get Tdap besides mom in a pregnant pt?

A

any family member who has not been recently vaccinated and will be in close contact with newborn.

57
Q

which influenza vaccine is safe for pregnant pts?

A

IM influenzae as this is the inactivated influenza. The intranasal influenza is a live attenuated vaccine and that is contraindicated in pregnancy

58
Q

is the pneumoccocal vaccine safe to give to pregnant pts?

A

it’s safe but only recommended for pts who have risk factors for invasive pnuemonia infection (chronic lung dx, immune deficiency)

59
Q

Why is the varicella zoster vaccine contraindicated in pregnant women?

A

it can cause maternal issues (pneumonia and encephalitis) and congenital defects like cataracts, chorioretinitis) complciations and non immune pregnant pts should betreated with prophylactic varicella zoster immunoglobulin.

60
Q

Incomplete abortion is a

A

partially dispelled remains of fetus

presents with heavy vaginal bleeding and resutling in hemodynamic instability and can have DIC.

Will see a dilated cervix with partial expulsion of the pregnancy

61
Q

management of ectopic pregnancy

A
62
Q

first trimester vaginal bleeding,

lower abdominal pain

complex adnexal mass on transvaginal ultrasound

can have hemodynamic instability

A

ectopic pregnancy

63
Q

risk factors for ectopic pregnancy are:

A

prior pelvic surgery, pelvic inflammatory dx, infertility and tobacco use

64
Q

Locations for ectopic pregnancy

A

fallopian tubes, ovaries, and cornua of uterus

65
Q

anemia, free fluid in posterior cul-de-sac, and hemodynamic instability in a young female

A

ruptured ectopic pregnancy life threatening emergency due to intraabdominal bleeding

see anemia

66
Q

how to manage someone with ectopic pregnancy?

A

expectantly or medically managed with methotrexate

expectant management is for women who have no adnexal mass on U/s and beta Hcg<200. Methotrexate can be used with no medical contraindications to therapy (immunodeficiency, renal failure, active pulm TB) and beta hcg<5000.

If someone is hemodynamically unstable, then pt needs surgical management (laparoscopy)

67
Q

vaginal bleeding and lower abdominal pain in third trimester and can have some uterine tenderness

A

abruptio placentae

68
Q

hydratiform mole is

A

first trimester vaginal bleeding with enlarged uterus and marked elevated beta hCG (>100K) and intrauterine heterogenous mass with cystic areas (snow storm appearance on ultrasound)

69
Q

anticoagulation during pregnancy

A
70
Q

anticoagulation prior to delivery of baby with VTE

A

hold anticoagulation with low molecular weight heparin for 24 hrs prior to delivery. During the 24 hrs, high risk for recurrenct (acute PE, proximal dvt within the last month), and so switch to unfractionated heparin (IV heparin) and then discontinued 4-6 hrs prior to surgery or delivery

Then anticoagulation is started 6 to 12 hrs after delivery and continued for >6 weeks post partum.

71
Q

Anemias of pregnancy

A

expected physiological levels of Hgb during pregnancy:

>11 g/dl in 1st trimester

>10.5 g/dl in 2nd trimester

>11 g/dl in 3rd trimester

baseline Hgb returns to normal after 6-8 weeks post partum. See increased fluid with pregnancy.

72
Q

Pruritic urticarial papules and plaques of pregnancy (PUPPP) is a

A

common specific dermatosis of pregnancy - seen by appearance of late third trimester erythematous itchy plaques in the distribution of striae.

Plaques are pruritic and hallmark of condition. NO jaundice or elevated LFTs and this is why this is not intrahepatic cholestasis of pregnancy.

condition resolves after delivery and 1st line tx is topical steroids of low to mid potency.

topical steroids do not relieve intrahepatic cholestasis of pregnancy

73
Q

management of breast pain (mastalgia)

A

breast pain is c_ommon and benign symptom_ in most women due to estrogen and progesterone changes in menstrual cycle.

pain is cyclical and beginning before menses and subsiding before onset of menses

pain is described as heavy, dull, diffuse and bilateral

Generalized swelling and mildly tender nodularity may be present but no discrete masses or nipple discharge should be there.

74
Q

how to treat bilateral cyclical mastalgia?

A

needs to treat pain with wearing a properly fitted braw with good breast support that miminizes breast movement.

can give tylenol for pain relief

danazol can be given for mastalgia but can cause permanent androgenic side effects (hirsutism) and increases risk for VTE

only get U/S or imaging of breast if there’s unilateral, non cyclical, or focal breast pain.

75
Q

what medications to stop prior to getting pregnant?

A

lisinopril

methotrexate- stop 3 months prior

leflunomide - extremely tetraogenic - need cholestyramine to remove drug from body and needs to be followed with drug level

mycophenolate mofetil stop 3 months prior

no NSAIDs. ACEi ARBs, phenytoin or valproic acid

ribavirin - for RSV treatment in immunocompromised pts . need to stop it 6 months prior to pregnancy

sirolimus and everolimus - stop 3-6 months prior to pregnancy

needs to get folate supplement.

76
Q

Are SSRI’s ok to take in pregnancy?

A

SSRI’s like citalopram, fluvoxamine, sertraline, are pregnancy category C agents that can be continued with pregnancy.

77
Q

diabetic goal A1c goal for pregnancy

which medication is ok to use while pregnant?
