what are recs for HPV vaccination if undergoing treatment for CIN2
current CDC recommendation: hPV vaccination if age 9-26 and consider adjuvant vaccine for previously unvaccinated people aged 27-45 undergoing treatment for CIN2.
- results in improved QOL and cost savings due to fewer paps/colposcopies.
What are recommendations for vaccines in pregnancy?
Tdap, inactive influenza, pneumococcal, menongococcal, Hep A and Hep B. Covid-19 in any trimester (and booster).
What are recommendations for flu treatment?
If suspected infection, give Oseltamivir (Tamiflu). If also have covid, give Paxlovid.
Illness severity assessment: SOB, new chest pain/pressure, unable to tolerate liquids, dehydration (dizziness), less responsive/confused, symptoms improved then returned? If yes»_space;go to ER. If moderate risk (comorbidities), see in ambulatory setting asap. need H&P, CXR, pulse ox.
Tamiflu: 75mg PO BID x5d or Peramivir 600mg IV once.
– can also do post-exposure chemoprophylaxis: 75mg once daily x 7d (if within 48hr exposure).
Paxlovid: 3 tablets (2 meds combined) twice daily x 5d.
What is PMS and PMDD?
PMS: cyclically occurring physical and mod sx occurring during luteal phase and resolve during/shortly after menstruation. sx=irritability, bloating, mood swings, breast tenderness, anxiety and tension.
– tx: Lifestyle modifications: decrease sugar/salt
Meds: SSRI, cyclic birth control pills (containing drospirenone bc least androgenic)
PMDD: depressive disorder, cyclic severe changes in affect occur in luteal phase and resolve during/shortly after menses. sx=mood lability, irritability, dysphoria, anxiety.

1 or more of following
anhedonia, concentration, lethargy, appetite changes, hypersonic, overwhelmed, physical (breast tenderness, muscle pain, bloating).
What is management of PMDD?
-SSRI: start in luteal phase or within sx onset or continuous
- combined OCPs: suppress ovulation nd hormonal fluctuations
- GnRH agonists w/ hormonal add-back: if severe refractory
-CBT
- exercise
- acupuncture
- NSAIDs: inhibit production of prostaglandins
- patient education
- calcium supplementation: manage physical and affective sx. 1000-1200mg/day
- surgery: BSO +/- hyst if severe and failed medical management. do 2mo trial of GnRH agonist before surgery to predict response to surgery.
What is counseling for spousal abuse?
screen for IPV/counsel at annual exams, new OB and qtrim.
- advise that exists among all SES and high as 3%
- ensure confidentiality, let pt use office phone to call hotline. offer materials and info about community resources. be supportive. assist pt in developing a safety plan.
What are details on rape?

psychotherapy=1st line
Meds: SSRI (sertraline then escitalopram). Fluoxetine 3rd line.
Anxiety: SSRI=1st line (sertraline or escitalopram) - start at 1/2 lowest dose to avoid SE (Agitation, insomnia).
- avoid benzos but can use as bridge until SSRI/SNRI effective. use for 2-4wks. use lorazepam.
- SE: nausea, dry mouth, insomnia, diarrhea, HA, dizziness, anxietation - decrease over time. sexual dysfunction persists.
- track sx q4wks (PHQ9, GAD7, EDPS). If sx resolve, continue 6-12mo to avoid relapse.
What is management of bipolar disorder in pregnancy?
continue mood stabilizers (except valproate bc teratogenic- NTD, craniofacial/limb anomalies).
- untreated BPD has incr risk PP psychosis, APO (FGR, PTD).
- screen for GDM if using antipsychotics
Lithium: if in 1st tri, detailed anatomy US (Ebstein’s anomaly). monitor dosing 2/2 narrow therapeutic window (goal 0.6-1.0). Crosses the placenta and neonatal high levels=hypotonia, lethargy, respiratory difficulties. breastfeeding controversial.
Mood stabilizers: lithium
Anti-convulsant: lamotrigene
Anti-psychotic: haldol, olanzapine, quetiapine, risperidone
Pre-concepcion: incr folate to 4mg/day.
What are neonatal risks with SSRI?
- persistent pulmonary hypertension of newborn (PPHN) - rare but potentially fatal. respiratory distress 2/2 vasoconstriction in lung. sertraline=least likely to cause this!
- Neonatal adaptation syndrome: irritability, restlessness, poor feeding, hypothermia. resolves within 2 weeks. 10-30% incidence. common w/ fluoxetine and paroxetine. Need Peds to eval.
What are screening tools for depression and anxiety?
EPDS: positive screen is >10
PHQ9
GAD-7: score 15 is severe
screen at IPV and each trimester. screen for bipolar disorder before starting tx for anxiety/depression because can precipitate mania if underlying depression.

- RCVS reversible encephalopathy vasoconstriction syndrome - abnormal cerebral angiography on MRI/CT. diffuse vasoconstriction of cerebral arteries. sudden HA, transient blindness and confusion, rapid improvement postpartum.
