A midwife refers a 28-year-old primigravid woman from Sudan at 22 weeks with a World Health Organisation (WHO) classification Type 3 female genital mutilation performed at the age of eight. What is the recommended management plan? Select one: a. Antenatal deinfibulation b. Elective caesarean section c. Deinfibulation in labour d. Episiotomy
?a Rationale (RANZCOG): If adequate VE is unlikely to be possible due to introital narrowing, advisable to offer antenatal deinfibulation, usually 2nd trimester but can be at any time 1st stage labour if necessary. FGM is not usually an indication for caesarean section. Not necessary to routinely perform a mediolateral episiotomy... but it will frequently be required due to increased scarring & lack of normal skin elasticity at the vaginal introitus

Which of the following changes in the cardiovascular and respiratory systems is abnormal in pregnancy? a. Increased pulmonary vascular markings b. Resting pulse rate of 100bpm c. Systolic murmur d. Alteration of the cardiac axis on ECG
A Circulation, Vol. 130, No. 12, 'Cardiovascular Physiology of Pregnancy', Sanghavi et al. b). "heart rate increases progressively throughout the pregnancy by 10-20 bpm, reaching a max HR in the 3rd trimester. Overall change in HR represents a 20%-25% increase over baseline" c). "mild 4-chamber dilation of the heart in pregnancy, there are changes in heart sounds. After the 1st trimester, in the majority of mothers, the first sound is louder and has an exaggerated split (resulting from early mitral closure), an ejection systolic flow murmur is detected in 90%, a 3rd heart sound is detected in 80%, and an AV diastolic flow murmur is detected in 20%. d). ECG changes in a normal pregnancy reflect the increased HR with minor L/R shifts in the QRS axis but no sig changes in ECG time intervals.

A midwife refers a 28-year-old primigravid woman from Sudan at 22 weeks with a World Health Organisation (WHO) classification Type 3 female genital mutilation performed at the age of eight. What is the recommended management plan? a. Antenatal deinfibulation b. Episiotomy c. Deinfibulation in labour d. Elective caesarean section
A RANZCOG: "In women where antenatal assessment indicates that adequate vaginal examination is unlikely to be possible due to introital narrowing, it is advisable to offer antenatal deinfibulation (see below). This is most commonly performed during the second trimester but can be carried out at any time during pregnancy, or in the first stage of labour if necessary. FGM is not usually an indication for caesarean section." "It is not necessary to routinely perform a mediolateral episiotomy in women with a history of FGM, whether or not deinfibulation has been performed, but it will frequently be required due to increased scarring and lack of normal skin elasticity at the vaginal introitus"
A primigravid woman is in labour at 36 weeks gestation with an uncomplicated twin pregnancy. Epidural analgesia is effective. The first twin was delivered five minutes ago by low vacuum extraction.

Postpartum haemorrhage is a rare cause of maternal morbidity c. If the use of uterotonics fail, hysterectomy is then required d. Ergometrine should never be used in those with hypertension
A a - Tone (70%), Tissue (10-20%), Trauma (10-20%), Thrombin (<1%) Re: d - Ergometrine should be avoided if >140sys, but can be used judiciously in major/severe PPH
A primigravid woman is in labour with an effective epidural at 38 weeks. Her assessments are as follows: Time 1200 & 1300, Cervical dilation 10cm, Cervical effacement fully, membranes ruptured Position 1200 = ROT, 1300 = ROA; Station 1200 = 1cm below spines, 1300 = 2cm below; Moulding 1200 = +, 1300 = ++ Which of the following is correct? Select one: a. Epidural analgesia increases the chance of instrumental delivery. b. An instrumental delivery is indicated if she has not delivered after 30 minutes of active pushing. c. The increase in moulding suggests an obstructed labour and she requires a caesarean section. d. Epidural analgesia increases the chance of caesarean in labour.
A a&d). 'NICE Guideline: Intrapartum care for healthy women & babies', P. 31. Risk can be reduced by delaying pushing for 1hr post-full cervical dilatation. b). NICE guideline, P. 60 - 'diagnose delay in active 2nd stage when >2Hrs & refer to healthcare professional trained to undertake an operative vaginal birth if birth is not imminent' c). RCOG green-top guideline 26 'Assisted Vaginal Birth', P. e85 = when assessing re ?instrumental. caput & moulding should be no more than +2. Mod moulding (+2) = parietal bones are overlapped but easily reduced; severe moulding (+3) = parietal bones have overlapped & are irreducible, indicating cephalopelvic disproportion.
The mother of a 6-month-old baby has not had a menstrual period since delivery. She is breastfeeding the baby three or four times per day. The baby is sleeping for eight hours each night. She wants to continue breastfeeding but does not want another pregnancy at this stage. Which of the following statements is INCORRECT? a. Contraception is not required while she is breastfeeding and amenorrhoeic b. Introducing solids to the baby's diet can reduce the effectiveness of contraceptive protection from breastfeeding c. The combined oral contraceptive pill can supress lactation d. Medroxyprogesterone acetate (Depo Provera) does not suppress lactation
A a). 6mths is the conservative cut-off point for LAM. Need to feed during night too. b). True, however... if you still breastfeed the same amount and prior to each meal it may be possible to continue LAM https://www.breastfeeding.asn.au/bfinfo/lactational-amenorrhea-method-lam-postpartum-contraception c). If you are breastfeeding you cannot take ...COCP because the hormones will decrease (dry up) your breast milk. (After 6 weeks you may start the COCP). https://www.wslhd.health.nsw.gov.au/ArticleDocuments/1022/Fact%20sheet%20Progesterone%20Only%20Pill%20POP%20FINAL%20Jan2018.pdf.aspx d). Only a very small amount of the dose is passed on to your baby through breastfeeding and it does not affect the amount of milk you produce. The contraceptive injection is 94-99.8% effective. If you stop using Depo-Provera® it may take some time for the chance of getting pregnant to return to normal.

A https://americanpregnancy.org/healthy-pregnancy/birth-defects/congenital-cmv-birth-defects-26719/ Highest risk of transmission from mother to baby if primary CMV infection in 3rd trimester (40-70%). Lower if the primary infection begins in the first or second trimesters (30-40%) In general, 1/150-200 babies in the USA is born with congenital CMV. This makes CMV the most frequent congenital viral infection. Though this seems like a large percentage of births, only 1/5 of these infants born with congenital CMV will experience any adverse symptoms or long-term issues.

She has CMV lgM and lgG positive. a. her that she currently has an active CMV infection. b. her to have amniocentesis. c. a repeat test in two weeks. d. that the risk the baby will develop asymptomatic congenital CMV is less than 10%.
A https://americanpregnancy.org/healthy-pregnancy/birth-defects/congenital-cmv-birth-defects-26719/ a). IgM & IgG = primary infection. b). While you can use amniocentesis to assess baby's CMV status (end of 3rd trimester, or in the 14-20 week range), timing isn't right and is high-intervention for questionable benefit to management guidance. c). Wouldn't change management? Would look for if IgM has resolved? d). 10-20% of babies with congenital CMV that are NOT symptomatic at birth will have some degree of long-term hearing loss

At the routine antenatal screening tests, a 20-year-old woman has negative RPR (Rapid Plasma Reagin) and positive TPHA (Treponema pallidum haemagglutination). The most likely explanation is that: a. the patient probably has early syphilis. b. the patient probably has been treated for syphilis in the past. c. the result is probably a biological false positive. d. the patient probably has late latent syphilis.
B a). Early syphilis = expect positive RPR/VDRL, which declines over 1yr. TPHA during the primary phase may be negative for antibodies, especially if testing is performed during the first 1-2wks after symptom onset" (ie. Need time for an adaptive immune response) b). Possible c). TPHA has 98-100% specificity -https://www1.health.gov.au/internet/main/publishing.nsf/Content/cda-phln-syphilis.htm Non-treponemal tests (RPR, VDRL) are prone to biological false positives, not TPHA d).

A primigravid woman at 38 weeks gestation presents in labour with a singleton pregnancy with an undiagnosed breech presentation. She has progressed rapidly and is now fully dilated. Which of the following is true? Select one: a. An extended breech is more hazardous than a footling breech. b. The risk of short-term neonatal complications is four times higher with vaginal breech compared to caesarean. c. The Mauriceau Smellie Veit manoeuvre will help to prevent a nuchal arm. d. In the 'term breech' trial, entry criteria for inclusion included an ultrasound estimate of fetal weight.
B a). QLD ambulance - Footling breech = increased risk of prolapsed cord. eMedscape - 0-2% frank breech, 5-10% complete breech, 10-25% footling breech. b). Controversial. eMedscape - re term breech trial: "The composite measurement of either perinatal mortality or serious neonatal morbidity by 6 weeks of life was significantly lower in the planned cesarean group than in the planned vaginal group (5% vs 1.6%, P< .0001)." https://www.ogmagazine.org.au/14/2-14/term-breech-trial/) - "The vaginal delivery versus caesarean section perinatal morbidity rates were calculated as 11/1038 vs 5/1038, with a p value of 0.2, which is not statistically significant" and 2yr F/U = nil difference in infant death rates or neurodevelopmental delay. c). MSV manoeuvre holds head in flexed position to allow passage of smallest diameter. SA Perinatal Practice Guideline 'Breech Presentation', P.10 - "If there are nuchal arms attempt Lovset's manoeuvre. This may bring the posterior arm down far enough to flex it and effect delivery" d).

1. A 24-year-old woman has a presumptive diagnosis of unruptured ectopic pregnancy. Which of the following is true? a. Salpingostomy must be followed up with serial measurement of beta-hCG levels b. Serum progesterone is of no value in making the diagnosis c. Salpingostomy is associated with a negligible risk of persistent ectopic pregnancy d. Linear salpingostomy has been shown in randomised controlled trials to be associated with a better future pregnancy rate than salpingectomy
a RCOG 'The Mgmt of Tubal Pregnancy' (2010) a). Australian Family Physician - Early pregnancy bleeding; Volume 45, No.5, May 2016 Pages 283-286 - "In women who have had a salpingostomy, hCG levels should be measured weekly until negative due to the potential for retained pregnancy tissue in the affected tube. In the case of a salpingectomy, histological confirmation of a tubal pregnancy is usually all that is required." b). Am Fam Physician. 2005 Nov 1, 'Dx & mgmt. of ectopic pregnancy';72(9):1707-1714. Serum progesterone levels can detect pregnancy failure and identify patients at risk for ectopic pregnancy, but they are not diagnostic of ectopic pregnancy. Single progesterone level to distinguish ectopic pregnancy from non-ectopic pregnancy = 15% sens, >90% spec; Single progesterone level to distinguish pregnancy failure from viable intrauterine pregnancy = 95% sens, 40% spec c). Persistent ectopic in 5-10% cases - https://www.surgeryencyclopedia.com/Pa-St/Salpingostomy.html d). In the presence of a healthy contralateral tube there is no clear evidence that salpingotomy should be used in preference to salpingectomy. "...reviews show there is not an increased chance of subsequent intrauterine pregnancy after salpingotomy compared with salpingectomy" Addit: Medical mgmt. = b-HCG<3000IU/L = Methotrexate [50mg/m2, im, STAT] & b-HCG @ D4, 7, further if not falling by >15%
Regarding Tibolone, which one of the following statements is correct? a. It increases sex hormone binding globulin (SHBG) b. It has significant breast stimulation properties c. It is a synthetic oestrogen d. It does not increase the risk of venous thromboembolism (VTE)
a) Aust. Menopause Soc. (AMS) MHT info sheet - "Androgenic effects are thought to enhance testosterone availability by reducing sex hormone binding globulin (SHBG)." b). It doesn't increase breast density [AMS Info Sheet & PMID 11967497] c). AMS Info Sheet - "Tibolone is a synthetic steroid hormone derived from the Mexican yam. The metabolites of tibolone have estrogenic, androgenic and progestogenic effects" (However it is contraindicated in women who have had BrCa). "Tibolone is a synthetic steroid molecule which is, in essence, a progestogen" d). Controversial. AMS info sheet & NPS medicinewise - Lack of data re DVT. https://www.menopause.org.au/hp/information-sheets/1195-venous-thrombosis-thromboembolism-risk-2018 - "Tibolone has been associated with an increased risk of stroke but the pooled data from four studies did not find that tibolone was associated with the risk of VTE"

A 32-year-old woman presents with a 12 week history of postcoital bleeding. Her periods are regular and her LMP was two weeks ago. She has taken the same combined oral contraceptive pill for eight years. She describes no dyspareunia or abnormal vaginal discharge. Her last cervical screening test was one year ago and was normal. All the following could account for her symptoms EXCEPT: a. ectropion. b. nabothian cyst. c. cervical polyp. d. cervical cancer.
b a). Ectropion is a common cause of post-coital bleeding (5-25% women w ectropion; esp in 3rd trimester) b). https://www.draliabadi.com/gynecology/cervical-conditions/nabothian-cysts/ - pus/mucus D/C is more common, as the etiology is overgrowth of epithelial cells over a cervical mucus gland c). PMID: 25045355 - "There are multiple etiologies for this common complaint in which most are benign such as cervicitis or cervical polyps. However, the most serious cause of postcoital bleeding is cervical cancer" d). Up-to-Date: About 11 percent of women with cervical cancer present with postcoital bleeding (range 0.7 to 39 percent)

Pearl Index = the number of contraceptive failures for a birth control method per 100 woman years (HWY) of use.
Regarding Erb's palsy, which of the following is correct? Select one: a. It occurs because of stretching of C8/T1 nerve roots. b. It persists longer than six months in 50% of cases. c. It follows 5-15% of all cases of shoulder dystocia. d. It could be prevented mostly by correct antenatal identification of selected cases needing caesarean section
d? a). Klumpke's paralysis - Lower BP injury (C8, T1) Erb's Palsy = upper brachial plexus (C5, 6) eg. hyperextension between the head & shoulder during difficult childbirth. - Paralysis of muscles responsible for abduct, flex & lateral rotation, hence arm hangs straight at side in medial rotation (pronated) w wrist in the 'waiter's tip' position C5 myotome = deltoid, some elbow flexion C6 myotome = biceps, Brachioradialis (elbow flexion) and supination b). RWH 'Shoulder Dystocia' guideline = generally recovers within 12 months. PMID: 19680484 - the rate of complete recovery is 80-96%, esp if improvement begins in the first 2wks. c). Unable to verify this stat. Not in RANZCOG, RCOG, RWH guidelines, Google. See PMID: 19680484 for good discussion. d). RFs = LGA (eg. GDM) and shoulder dystocia. Reduced but can still be seen in LUSCs
