    Incorrect

    • You are called to see a 24 year old patient in A&E. She is 34 weeks gestation and her blood pressure is 149/98. Urine dip shows protein 3+. You send a for a protein:creatinine ratio. What level would be diagnostic of significant proteinuria?

      Your Answer: >100mg/mmol

      Correct Answer: >30 mg/mmol

      Explanation:

      Significant proteinuria = urinary protein:creatinine ratio >30 mg/mmol or 24-hour urine collection result shows greater than 300 mg protein

    Correct

    • A 28-year-old lady is complaining of mucopurulent vaginal discharge. On examination, copious amounts of thick mucoid material is found to be draining out of a large cervical erosion. She has had regular pap smears since 16 years of age, which have all been normal. Her last smear was done 4 months prior.

      What is the best next step in her management?

      Your Answer: Cauterisation of the cervix.

      Explanation:

      The best next step in management would be to remove the cervical ectropion using cautery. This would usually be performed under anaesthesia. It can take up to a month to heal following the procedure. Vaginal pessaries and antibiotics are typically not effective.

      Indications for a cone biopsy include an abnormal pap smear, lesion suspected to be a CIN on colposcopic examination that cannot be fully visualised as well if there is a histological discrepancy between the smear and biopsy. Colposcopic examination is also unnecessary at this stage since she has not complained of any abnormal per vaginal bleed nor is her last pap smear abnormal.

      Since the discharge is now affecting the patient’s life, treatment should be given so reassuring her that no treatment is needed is not appropriate.

    Incorrect

    • Among the following which is incorrect regarding hypothyroidism in pregnancy?

      Your Answer: Children born to women whose hypothyroidism was inadequately treated in pregnancy are at increased risk of neuropsychological impairment

      Correct Answer: Thyroxine requirement does not increase in pregnancy and maintenance dose must be continued

      Explanation:

      Thyroxine requirement during pregnancy will increases by 25 to 30 percent, which is seen as early as fifth week of pregnancy.

      Children born to those women whose hypothyroidism was inadequately treated during pregnancy, are at higher risk for developing neuropsychiatric impairments.

      When a woman who is on thyroxine is planning to conceive, they are advised to increase their thyroxine dose by 30 percent at the time of confirmation of pregnancy.

      During pregnancy TSH also should be monitored at every 8 to 10 weeks, with necessary dose adjustments.

      Dose requirements of thyroxine will return to pre-pregnancy level soon after delivery and it will not change according to whether the mother is breastfeeding or not.

    Incorrect

    • A 56 year old lady presents with a vulval itch and discolouration. A biopsy conforms Lichen Sclerosis (LS). What is the risk of developing squamous cell carcinoma compared to patients with a normal vulval biopsy?

      Your Answer: 5-15%

      Correct Answer:

      Explanation:

      Lichen Sclerosis is a destructive inflammatory condition that effects the anogenital region of women. It effects around 1 in 300 women. It destroys the subdermal layers of the skin resulting in hyalinization of the skin leading to parchment paper appearance of the skin. It is associated with vulval cancer and it is estimated that the risk of developing vulval cancer after lichen sclerosis is around 3-5%.

    Correct

    • Etiological factors in spontaneous abortion include:

      Your Answer: All of the options given

      Explanation:

      Spontaneous abortion is the loss of pregnancy naturally before twenty weeks of gestation. Colloquially, spontaneous abortion is referred to as a ‘miscarriage’ to avoid association with induced abortion. Early pregnancy loss refers only to spontaneous abortion in the first trimester. In 50% of cases, early pregnancy loss is believed to be due to fetal chromosomal abnormalities. Advanced maternal age and previous early pregnancy loss are the most common risk factors. For example, the incidence of early pregnancy loss in women 20-30 years of age is only 9 to 17%, while the incidence at 45 years of maternal age is 80%. Other risk factors include alcohol consumption, smoking, and cocaine use.

      Several chronic diseases can precipitate spontaneous abortion, including diabetes, celiac disease, and autoimmune conditions, particularly anti-phospholipid antibody syndrome. Rapid conception after delivery and infections, such as cervicitis, vaginitis, HIV infection, syphilis, and malaria, are also common risk factors. Another important risk factor is exposure to environmental contaminants, including arsenic, lead, and organic solvents. Finally, structural uterine abnormalities, such as congenital anomalies, leiomyoma, and intrauterine adhesions, have been shown to increase the risk of spontaneous abortion.

    Correct

    • Regarding urinary tract infection (UTI) in pregnancy. What is the most common causative organism of urinary tract infection?

      Your Answer: Escherichia coli

      Explanation:

      E.coli is the most common cause of UTI. Other organisms include pseudomonas, proteus and klebsiella.

      NICE guidelines: UTI in pregnancy (updated in July 2015)

      Send urine for culture and sensitivity from all women in whom UTI is suspected before starting empirical antibiotics and 7 days after antibiotic treatment is completed.
      Prescribe an antibiotic to all women with suspected UTI (awaiting culture result is not advised)
      Although local antibiotic resistance needs to be taken into account the following is advised in terms of antibiotic selection:
      1. Nitrofurantoin 50 mg QDS (or 100 mg MR BD) for 7 days.
      2. Trimethoprim 200 mg twice daily, for 7 days
      Give folic acid 5 mg OD if it is the 1st trimester
      Do not give trimethoprim if the woman is folate deficient, taking a folate antagonist, or has been treated with trimethoprim in the past year.
      3. Cefalexin 500 mg BD (or 250 mg 6qds) for 7 days

      Correct Answer: The cardinal ligament

      Explanation:

      The cardinal ligament (or Mackenrodt’s ligament, lateral or transverse cervical ligament) is a major ligament of the uterus. It is located at the base of the broad ligament of the uterus. It attaches the cervix to the lateral pelvic wall by its attachment to the Obturator fascia of the Obturator internus muscle, and is continuous externally with the fibrous tissue that surrounds the pelvic blood vessels. It thus provides support to the uterus.

    • A 30-year-old woman with histories of obesity and type 2 diabetes Mellitus comes to you for advice as she is planning to conceive in next three months. Her blood sugar levels are under control with a HBA1C value of 6%.

      Among the following which is an essential supplement for her?

      Your Answer: Folic acid

      Explanation:

      Patient mentioned above is a known case of type 2 diabetes which makes her at high risk of having neural tube defects. She should be advised to start taking a high dose of (5mg) folic acid supplement daily for at least 1-month prior to conception and it should be continued upto 12 weeks of her pregnancy.

      Folate, which is a water-soluble B vitamin, is usually obtained from diet or through supplementation. For those patients with a history of type 2 diabetes mellitus, who are planning for pregnancy, high doses are recommended to prevent any possible neural tube defects.

      Vitamin A is not safe and should be avoided in pregnancy due to chances for toxicity.

      Vitamin C and iron are not considered as essential vitamins to be taken during pregnancy.

    Incorrect

    • A 35-year-old female patient, gravida 1 para 1, visits the clinic to have her contraception method evaluated. The patient has had unpredictable bleeding for the past 8 months since receiving a subdermal progestin implant and begs that it be removed. She used to use combined oral contraceptives and would like to go back to it. The patient has primary hypertension, which she was diagnosed with last year and is effectively controlled on hydrochlorothiazide. She does not take any other medications or have any allergies. Her father and brother both suffer from type 2 diabetes. The patient does not smoke, drink, or use illegal drugs.

      24 kg/m2 is her BMI. Blood pressure is 130/75 millimetres of mercury. Physical examinations are all normal. Which of the following is increased by using combination oral contraceptives?

      Your Answer: Type 2 diabetes mellitus

      Correct Answer: Worsening hypertension

      Explanation:

      Overt hypertension, developing in about 5% of Pill users, and increases in blood pressure (but within normal limits) in many more is believed to be the result of changes in the renin-angiotensin-aldosterone system, particularly a consistent and marked increase in the plasma renin substrate concentrations. The mechanisms for the hypertensive response are unclear since normal women may demonstrate marked changes in the renin system. A failure of the kidneys to fully suppress renal renin secretion could thus be an important predisposing factor. These observations provide guidelines for the prescription of oral contraceptives. A baseline blood pressure measurement should be obtained, and blood pressure and weight should be followed at 2- or 3-month intervals during treatment. Oral contraceptive therapy should be contraindicated for individuals with a history of hypertension, renal disease, toxaemia, or fluid retention. A positive family history of hypertension, women for whom long-term therapy is indicated, and groups such as blacks, especially prone to hypertensive phenomena, are all relative contraindications for the Pill.

      COCs do not increase the risk of developing breast and endometrial cancer, Type 2 DM or breast fibroadenoma.

    Correct

    • A 32-year-old mother with a 9-year-old child is considering having a second child. Her first pregnancy was complicated by puerperal psychosis. Following electroconvulsive therapy (ECT), she promptly recovered and has been well until now. She is in excellent health and her husband has been very supportive. According to patient files, she was noted to be an excellent mother.

      What would be the most appropriate advice?

      Your Answer: There is a 15-20% chance of recurrence of psychosis postpartum.

      Explanation:

      Puerperal psychosis seems to be mainly hereditary and closely associated with bipolar disorder especially the manic type, rather than being a distinct condition with a group of classical symptoms or course. Postpartum psychoses typically have an abrupt onset within 2 weeks of delivery and may have rapid progression of symptoms. Fortunately, it is generally a brief condition and responds well to prompt management. If the condition is threatening the mother and/or baby’s safety, hospital admission is warranted. A patient can present with a wide variety of psychotic symptoms ranging from delusion, passivity phenomenon, catatonia, and hallucinations. While depression and mania may be the predominating features, it is not surprising to see symptoms such as confusion and stupor. Although the rate of incidence is about 1 in 1000 pregnancies, it is seen in about 20% of women who previously had bipolar episodes prior to pregnancy. It has not been shown to be linked with factors such as twin pregnancies, stillbirth, breastfeeding or being a single parent. However, it might be more commonly seen in women who are first-time mothers and pregnancy terminations.

      The risk of recurrence is 20%. Unfortunately, there is no specific treatment guideline but organic causes should first be ruled out. First generation/typical anti-psychotics are often associated with extrapyramidal symptoms. Nowadays, atypical antipsychotics such as risperidone or olanzapine can be used along with lithium which is a mood stabiliser. As of now, there hasn’t been any significant side effects as a result of second generation antipsychotic use in pregnancy. While women are usually advised to stop breast-feeding, it might be unnecessary except if the mother is being treated with lithium which has been reported to cause side effects on the infants in a few instances. ECT is considered to be highly efficacious for all types of postpartum psychosis and may be necessary if the mother’s condition is life-threatening to herself or/and the baby. If untreated, puerperal psychosis might persist for 6 months or even longer.

      The options of saying ‘in view of her age and previous problem, further pregnancies are out of the question’ and so is ‘By all means start another pregnancy and see how she feels about it. If she has misgivings, then have the pregnancy terminated.’ are inappropriate.

      As mentioned earlier, considering there is a 20% chance of recurrence it is not correct to say that since she had good outcomes with her first pregnancy, the risk of recurrence is minimal.

      Anti-psychotics are not recommended to be used routinely both during pregnancy and lactation due to the absence of long-term research on children with intrauterine and breastmilk exposure to the drugs. Hence it is not right to conclude that ‘if she gets pregnant then she should take prophylactic antipsychotics throughout the pregnancy’ as it contradicts current guidelines. Each case should be individualised and the risks compared with the benefits to decide whether anti-psychotics should be given during pregnancy. It is important to obtain informed consent from both the mother and partner with documentation.

      Should the mother deteriorates during the pregnancy that she no longer is capable of making decisions about treatment, then an application for temporary guardianship should be carried out to ensure that she can be continued on the appropriate treatment.

Upon discharge, there is a plan to start her on warfarin. When this was explained, the patient was reluctant to take warfarin since she thinks it might cause problems to the baby because she is planning to breastfeed.

      Which of the following is considered correct regarding warfarin and breastfeeding?

      Your Answer: She should continue to breastfeed her baby while she is on warfarin

      Explanation:

      No adverse reactions in breastfed infants have been reported from maternal warfarin use during lactation, even with a dose of 25 mg daily for 7 days. There is a consensus that maternal warfarin therapy during breastfeeding poses little risk to the breastfed infant.

    Incorrect

    • A patient, in her third pregnancy with a history of two consecutive spontaneous abortions, presents at 12 weeks of gestation. She has had regular menstrual cycles, lasting 30 days in duration. Just prior to coming for her assessment, she reports passing a moderate amount of blood with clots per vaginally along with some intermittent lower abdominal pain. On examination, her cervical canal readily admitted one finger. Bimanual palpation found a uterus corresponding to the size of a pregnancy of 8 weeks’ duration.

      Which is the most appropriate next step in managing this patient?

      Your Answer: Curettage.

      Correct Answer: Vaginal ultrasound.

      Explanation:

      It is essential to notice the important details mentioned in the case scenario. These would be the details about her menstruation, a smaller than dates uterus and an open cervix. A smaller than expected uterine size could be caused by her passing out some tissue earlier or it could be due to the foetus having been dead for some time. The finding of an open cervix would be in line with the fact that she had passed out some fetal tissue or it could signify that she is experiencing an inevitable miscarriage (while all fetal tissue is still kept within her uterus).

      The likely diagnoses that should be considered for this case would be miscarriage (threatened, incomplete, complete and missed), cervical insufficiency, and ectopic pregnancy. A smaller than dates uterus and an open cervix makes threatened abortion an unlikely diagnosis. Her clinical findings could be expected in both an incomplete abortion and a complete abortion.
      In ectopic pregnancy, although there would be a smaller than dates uterus, the cervical os would usually be closed. Cervical insufficiency is probable due to an open os but the uterine size would be expected to correspond to her dates, making it also less likely than a miscarriage.

      Since she most likely has had a miscarriage (be it incomplete or complete), the next best step would be to do a per vaginal ultrasound scan which could show whether or not products of conception are still present within the uterine cavity. If present, it would be an incomplete miscarriage which would warrant a dilatation and curettage; if absent, it is a complete miscarriage so D&C would not be needed.

      In view of her open cervix and 12 weeks of amenorrhea, there is no indication for a pregnancy test nor assessment of her beta-hCG levels. Cervical ligation would only be indicated if the underlying issue was cervical incompetence, which is not in this case.

    Correct

    • A 29-year-old obese lady weighing 130 kilograms, is requesting for a prescription for the oral contraceptive pill (OCP). She has hirsutism and acne. She has also expressed that she occasionally suffers from migraines along with pins and needles in her left arm.

      Which is the best contraceptive for her?

      Your Answer: A barrier method of contraception.

      Explanation:

      OCPs which contain oestrogen and progesterone are contraindicated in women who have migraines associated with a neurological deficit or aura (pins and needles in this case). In such cases, the alternative would be Implanon (etonogestrel), however, there are mixed reviews and opinions regarding whether or not there is a decreased efficacy in heavier women. The absolute contraindication for Implanon is active breast cancer. Therefore, the best advice for her case would be some form of barrier contraceptive.

      When choosing a COCP (combined oral contraceptive pill), it is recommended that a formulation containing 20-30ug of ethinyl oestradiol is chosen. The progestogen part is responsible for prevention of conception and can be norgestrel or any other progestogens although the formulations containing norgestrel tend to be cheaper than more novel progestins such as cyproterone acetate as well as drospirenone. If the patient is known to have issues with excessive fluid retention, OCPs that has drospirenone would be the most suitable. However, if the patient is suspected to have PCOS, the best choice would be one that contains cyproterone acetate.

      Explanation:

      The yolk sac increases in size up until the 10th week reaching a maximum diameter of 6mm in normal pregnancy. After the 10th week the yolk sac will gradually disappear. It is usually sonographically undetectable by 20 weeks. A yolk sac greater than 6mm diameter is suspicious of failed pregnancy.

The current pregnancy had been uneventful without any remarkable problems in antenatal visits except for the first trimester nausea and vomiting.

      On arrival, she had a cervical dilation of 4 cm and the fetal head was at -1 station. After 5 hours, the cervical length and fetal head station are still the same despite regular uterine contractions. Suddenly, there is a sudden gush of blood, which is approximately 1000 ml and the fetal heart rate have dropped to 80 bpm on CTG.

      Which of the following could be the most likely cause for this presentation?

      Your Answer: Ruptured uterus

      Explanation:

      Due to the previous history of caesarean section, uterine rupture would be the most likely cause of bleeding in this patient who is at a prolonged active phase of first stage of labour.

      Maternal manifestations of uterine rupture are highly variable but some of its common features includes:
      – Constant abdominal pain, where the pain may not be present in sufficient amount, character, or location suggestive of uterine rupture and may be masked partially or completely by use of regional analgesia.
      – Signs of intra abdominal hemorrhage is a strong indication. Although hemorrhage is common feature, but signs and symptoms of intra-abdominal bleeding in cases of uterine rupture especially in those cases not associated with prior surgery may be subtle.
      – Vaginal bleeding is not considered as a cardinal symptom as it may be modest, despite major intra-abdominal hemorrhage.
      – Maternal tachycardia and hypotension
      – Cessation of uterine contractions
      – Loss of station of the fetal presenting part
      – Uterine tenderness
      As seen in this case, fetal bradycardia is the most common and characteristic clinical manifestation of uterine rupture, preceded by variable or late decelerations, but there is no other fetal heart rate pattern pathognomonic of rupture. Furthermore, fetal heart rate changes alone have a low sensitivity and specificity for diagnosing a case as uterine rupture.
      Pain and persistent vaginal bleeding despite the use of uterotonic agents are characteristic for postpartum uterine rupture. If the rupture extends into the bladder hematuria may also occur.
      A definite diagnosis of uterine rupture can be made only after laparotomy. Immediate cesarean section should be performed to save both the mother and the baby in cases where uterine rupture is suspected.

    Correct

    • Which of the following dugs is a strong inducer of cytochrome P450?

      Your Answer: Phenytoin

      Explanation:

      Antiepileptic, phenytoin more so than topiramate are inducers of cytochrome P450. They should not be given with COCPs. The metabolism of oestrogen and progestogen is increased by anti-epileptic drugs that induce cytochrome P450 leading to a loss of contraceptive effect.

    Incorrect

    • Where is fetal DHEA produced?

      Your Answer:

      Correct Answer: Adrenals

      Explanation:

      DHEA is formed in the mother’s adrenal gland as well as the fetal adrenal glands. These weak androgens are transported by the blood to the placenta and are converted into oestradiol, estrone and estriol in the trophoblast.
