Office Flashcards
Define early pregnancy loss
EPL = nonviable IUP with either an empty gestational sac or a gestational sac with embryo or fetus without fetal cardiac activity within the first 12 + 6/7 days.
Common, 10% of all clinically recognized pregnancies
Prolog - Office Q23.
Mifepristone
Mechanism of Action
Mifepristone = 19-nor steroid
Acts as a competitive progesterone-receptor antagonist and a corticosteroid-receptor antagonist.
Primes myometrium and cervix for prostaglandin activity
Combined mifepristone, misoprostol is superior to either alone
Prolog - Office Q23.
Misoprostol Dosing for Early Pregnancy Loss
800 micrograms vaginally
with one repeat dose as needed - no earlier than 3 hours after first dose and typically within 7 days if not response to first dose
Prolog - Office Q23.
What are the 7 types of ethical conflicts with Industry (per ACOG)?
- Product promotion to individual physicians by advertising, personal communication, and provision samples
- Support of educational activities for individual physicians
- Industry-sponsored device training
- Industry sponsorship of research
- Speakers bureaus
- Physicians as consultants to industry
- Ghostwriting
Prolog - Office Q24.
Most common nongyn, non obstetric patient complaint encountered by OB/GYNs?
Low back pain.
Acute = 4- 6 weeks
Subacute = 6- 12 weeks
Chronic = > 12 weeks
MCC of disability world wide
Best initial/ first line treatment of non-specific back pain = NSAIDS and PT (physical therapy).
Prolog - Office Q25.
Risk factors for ectopic pregnancy?
-Hx ectopic
-Fallopian tube damage
-Prior pelvic surgery
50% of women with ectopic will have no risk factors
Prolog - Office Q26.
After uterine aspiration, what drop in bHCG would suggest failed early pregnancy versus ectopic pregnancy?
For a non diagnostic uterine aspiration (aka no chorionic vili)..
-First bHCG should be obtained 12- 24 hours following aspiration.
-bHCG drop >50% = likely failed IUP
-bHCG drop 15- <50% = low threshold for treatment for ectopic pregnancy
-bHCG drop 10- 15%, considered a plateau = should be treated for presumed ectopic
Regardless all patients should be given ectopic precautions and continue to monitor quant to zero.
Prolog - Office Q26.
Pyogenic Granuloma
-Occurs in 5% of pregnancies
-Spontaneously resolves
-Inflammatory hyperplasia develops because of hormonal factors, local injury or local irritation
-Symptom will be bleeding gums when brushing or specific lesion noted
-If does not resolve postpartum, then may require surgical excision
Prolog - Office Q27.
Most common cause of hypothyroidism?
Autoimmune thyroiditis
-90% will have anti-thyroglobulin and anti-thyroid peroxidase (TPO) antibodies
NOTE
-There is a natural increase in TSH with age, the upper limit rare increases > 8
-This puts women at risk for misinterpreted abnormals and over treatment with levothyroxine.
Prolog - Office Q28
What are symptoms of over treatment of hypothyroidism with levothyroxine?
-Weight loss
-Increased frailty
-Cardiac tachyarrhythmia
-Excessive bone loss
Prolog - Office Q28
What is a risk of untreated subclinical hypothyroidism in women?
What is the most common cause of subclinical hypothyroidism in elderly women?
- Increased risk of metabolic syndrome
-Hashimoto thyroiditis
FACT There tends to be a tentative link between incidence of heart failure and TSH concentration > 10.
Prolog - Office Q28
What is the most sensitive test to diagnose autoimmune thyroid disease?
Thyroid peroxidase antibody
Prolog - Office Q28
What is the prevalence of heavy menstrual bleeding in adolescents?
34- 37%
MCC of acquired or congenital = von Willebrand disease
Prolog - Office Q29
What is the role of von willebrand factor?
-Functions in both platelet binding and aggregation
-Transports and aids function of factor VIII (intrinsic pathway)
Prolog - Office Q29
Describe the three types of Von Willebrand Disease
Type 1 = mildest, most common
- inherited A.D.
- Quantitative deficiency in vWF
Type 2 =
- Qualitative or functional defect in vWF activity
- Multiple subtypes with different inheritance
Type 3 = Most severe
- Inherited A.R.
- Complete absence of vWF
Prolog - Office Q29
What is the preferred treatment of acute heavy vaginal bleeding in adolescents?
- Medical therapy with Estrogen (and Iron should be given concurrently)
- Monophonic COCP given in “blast” fashion (multiple pills at once) or in a taper
- MC risk/side effect of high dose estrogen = nausea
-Can also add TXA with COCPs. Theoretical increased risk of thrombosis but no established studies.
Inpatient admission recommended with hd compromise, dizziness or continuing to soak a pad an hour
Prolog - Office Q29
most common sexually transmitted infection?
HPV
HPV vaccine:
-Begin as early as 9yo, 2 dose regimen
-Age >15, receive 3 doses.
-Efficacy demonstrated up to age 45.
-Age 27- 45 may be less effective, but ACOG still supports giving it.
Prolog - Office Q30
What vaccinations are recommended for healthcare workers?
-Influenza
-Hep B
-MMR
-Tetanus toxoid
-Varicella
-Meningococcal
-Tdap
Prolog - Office Q30
What are the recommendations for pneumococcal vaccine?
- < 2 yo
- > 2 yo with immunocompromised, T2DM, asplenia.
- > 65yo without immunocompromised. Cannot have cochlear implant or CSF leak.
-Not a routine vaccine for healthy adults or health care workers
Prolog - Office Q30
When is the Zoster vaccination recommended?
- Adults > 50yo
- Shingles prevention
Prolog - Office Q30
What are the tumor markers and their tumors?
-bHCG
-LDH
-AFP
-Inhibin
-CEA
-Testosterone, Estradiol
-ca-125 = epithelial
-bHCG = choriocarcinoma, embryonal
-LDH = dysgerminoma
-AFP = endodermal sinus, embryonal
-Inhibin = Granulosa cell tumor
-CEA = mucinous carcinoma
-Testosterone, Estradiol
Prolog - Office Q31
Regardless of ethnic and familial factors, what two mutations are routinely recommended for carrier screening?
-Cystic Fibrosis
-Spinal Muscular Atrophy (SMA)
Carrier screening ideally is offered pre pregnancy but should be offered to all pregnant individuals.
Prolog - Office Q32
What is the gene mutation in cystic fibrosis?
CFTR (cystic fibrosis transmembrane regulator) gene
-MC life-threatening autosomal recessive (AR) condition in non-hispanic white population
Prolog - Office Q32
What is the gene mutation for spinal muscular atrophy that indicates non-carrier (normal), carrier, versus disease state?
SMA = degenerative disease of spinal cord motor neurons.
SMN1 Mutation = survival motor neuron 1
Carrier screening requires quantitative PCR assay giving the number and copy of the gene. >90% detection rate.
Normal = both normal copies
Carrier = single normal copy
Silent carrier = two copies on same chromosome –> copy number appears normal (and gives sometimes false negative result). This type is MC in african americans.
