A serious complication with a miscarriage is DIC, a severe blood clotting condition and is more likely if there is a long time until the foetus and other tissues are passed, which is often the case in missed abortion.

Placental abruption is defined as the premature separation of placenta from uterus and the condition usually presents with bleeding, uterine contractions and fetal distress. It is one of the most significant cause of third-trimester bleeding and is often associated with fetal and maternal mortality and morbidity. In all pregnant women with vaginal bleeding in the second half of the pregnancy, this condition should be considered as a differential diagnoses.
Though vaginal bleeding is the most common presenting symptom reported by almost 80% of women with placental abruption, vaginal bleeding is concealed in 20% of women with placental abruption, therefore, absence of vaginal bleeding does not exclude placental abruption.

Symptoms and complications of placental abruption varies according to patient, frequency of appearance of some common features is as follows:
‌- Vaginal bleeding is the common presentation in 80% of patients.
‌- Abdominal or lower back pain with uterine tenderness is found in 70%
‌- Fetal distress is seen in 60% of women.
‌- Abnormal uterine contractions like hypertonic, high frequency contractions are seen in 35% cases.
‌- Idiopathic premature labor in 25% of patients.
‌- Fetal death in about 15% of cases.

Examination findings include vaginal bleeding, uterine contractions with or without tenderness, shock, absence of fetal heart sounds and increased fundal height due to an expanding hematoma. Shock is seen in class 3 placental abruption which represents almost 24% of all cases of placental abruption.

The life time risk of breast cancer in BRCA 2 gene is 45% and of ovarian cancer is 15%.

There are between 250 and 400 lobules in each testis. The lobule is a structural unit of the testis with each lobule contained in one of the intervals between fibrous septa which extend between the mediastinum testis and the tunica albuginea. Each lobule contains 1 to 3 seminiferous tubules.

There are 3 stages of labour. The 1st stage of labour starts from labour contractions till the time the cervix is fully dilated. Stage 2 is from complete cervical dilatation until the baby is born. The 3rd stage is from the birth of the baby, until the time the placenta is expelled.

Detrusor contraction is via Parasympathetic innervation of pelvic splanchnic nerves (S2-4). This also causes relaxation of the internal urethral sphincter Note contraction and relaxation of the external urethral sphincter is under somatic control.

Ultrasound findings in early pregnancy can help determine the viability of an intrauterine pregnancy. In the absence of a fetal heartbeat and no visible fetal pole, the mean gestational sac diameter should be measured. A sac diameter of less than 25mm on a transvaginal ultrasound scan is likely an indication of a miscarriage. In the presence of a fetal heartbeat, the crown-rump length should be less than 7mm according to NICE guidelines. Further scans are indicated 14 days later to confirm the diagnosis. The diagnosis of ‘pregnancy of uncertain viability’ is given in situations where there is inadequate ultrasound evidence to diagnose a miscarriage, such as a developing sac but no visualisation of a foetus with a heartbeat.
Ultrasound findings for partial molar pregnancy are an enlarged placenta with multiple diffuse anechogenic patches, while findings in a complete molar pregnancy include an enlarged uterus with multiple small anechogenic spaces (snowstorm appearance), or the bunch of grapes sign representing hydropic trophoblastic villi.

Warfarin is teratogenic if it is used in the first trimester. It causes bone defects and haemorrhages in the developing foetus. It causes the formation of multiple ossification centres in the long bones. Resulting in stippled epiphyses and hence deform long bones.

Pituitary tumours, the most common pathologic cause of galactorrhoea can result in hyperprolactinemia by producing prolactin or blocking the passage of dopamine from the hypothalamus to the pituitary gland. Approximately 30 percent of patients with chronic renal failure have elevated prolactin levels, possibly because of decreased renal clearance of prolactin. Primary hypothyroidism is a rare cause of galactorrhoea in children and adults. In patients with primary hypothyroidism, there is increased production of thyrotropin-releasing hormone, which may stimulate prolactin release. Nonpituitary malignancies, such as bronchogenic carcinoma, renal adenocarcinoma and Hodgkin’s and T-cell lymphomas, may also release prolactin.

In a person who is infected by streptococcus (Group B) should be started on benzylpenicillin as soon as possible. In case of allergy vancomycin should be started at 1g every 12 hours. Tetracyclines should be avoided in pregnancy.

This patient is presenting with a severe placental abruption causing fetal death and shock in the mother. The most appropriate initial management for the patient is to treat her shock with blood transfusions and exclude or treat any coagulation disorder resulting from the abruption. Delivery also needs to be expedited to remove the dead foetus. An amniotomy is usually all that is required to induce spontaneous labour as the uterus is usually very irritable. Spontaneous labour is likely to occur in this case, where the cervix is already 4 cm dilated and fully effaced.

Caesarean section is rarely needed to be done when the foetus is already dead.

Vaginal prostaglandin and an oxytocin (Syntocin®) infusion are not needed and unlikely to be required.

Ultrasound examination to confirm the diagnosis and fetal death is also unnecessary given the clinical and Doppler findings.

The best regimen would be to have no intercourse in the follicular phase of the cycle and then commence it two days after a temperature rise of 0.3C and continue then onwards. When deciding the best contraceptive method, one has to consider two factors-the duration of survival of sperm in the uterus and body temperature in relation to ovulation. For this case, since her cycle length varies from 24 to 30 days, the earliest time in which ovulation would occur would be 14 days before her shortest cycle i.e. day 10. Intercourse has to be avoided from day 4 of her cycle just in case the current cycle is short because sperm can survive up to 6 days in the uterus. Day 4 would be the day her menses would end and as this couple avoids intercourse during her menstruation, there would be no intercourse during the follicular phase of her cycle.

During ovulation, her serum progesterone levels would start to increase, causing a 0.3°C to 0.4°C increase in her body temperature within 2-3 days of ovulating. This elevation in temperature would remain until close to when her period starts. The ovum can only be fertilised for roughly 24 hours after ovulation has taken place. Resuming sexual intercourse once her temperature has risen for 2 days would suggest that ovulation had already taken place 3-4 days earlier and so it is unlikely for pregnancy to occur.

Options that include intercourse during any part of her follicular phase is not correct. Hence, the only option that satisfies the above criteria would be intercourse avoidance during her follicular phase and to resume 2 days following a rise of 0.03°C in body temperature.

When cervical biopsy or colposcopy doesn’t explain the severity of the pap smear results cone biopsy is done. In 10% of biopsies, results will be different from that of the pap smear as in this patient with pap smear showing HSIL and colposcopy showing chronic cervicitis.

In such cases conization is indicated. Repeating the pap smear could risk prompt management of a serious problem. No destructive procedure, ablation or cryotherapy, should be done before diagnosis is certain.

Most women lose about 35-40 ml of blood on average during each menstrual cycle. The maximum amount of blood loss is 80 ml after which blood loss of more than 80 ml is defined as heavy menstrual bleeding, formerly known as menorrhagia.

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.

The maximum dose of lidocaine with adrenaline is 7mg/kg.

Serum prolactin levels are increased during suckling. Some other conditions in which serum prolactin is increased consist of: prolactin secreting brain tumours, anti psychotic drugs and hypothyroidism. It can also be increased in pregnancy, nipple stimulation and stress.

Breakthrough bleeding, breast tenderness, nausea, bloating, amenorrhea, hypertension, venous thromboembolic disease, increased risk of cervical cancer with decreased risk of ovarian & endometrial cancer, liver disorders like hepatic adenoma and increase in triglycerides due to estrogen component are the common side effects & risks of using combination oral contraceptives.

Patient in the given case mentioned symptoms of primary dysmenorrhea, which is recurrent lower abdominal pain associated with menstruation. Combination estrogen-progestin oral contraceptive pills (OCPs) are considered as the first-line treatment for dysmenorrhea in sexually active patients as OCPs help to reduce pain by thinning the endometrial lining, reducing prostaglandin release and by decreasing uterine contractions.
Nausea, bloating and breast tenderness, are considered as the early side effects of OCPs and will usually improve with continued use. The most common side effect is breakthrough bleeding which is usually associated with lower estrogen doses and other adverse effects caused by the pills include hypertension, increased risk of cervical cancer and venous thromboembolism. Although common perception considers weight gain as a side effect, several studies have shown that no significant weight gain is associated with OCPs, particularly with low-dose formulations.  Considering this, the patient should be reassured that her weight gain is not associated with regular use of OCPs.

In patients who are not sexually active, nonsteroidal anti-inflammatory drugs are considered as the first-line treatment for primary dysmenorrhea. As stopping contraception will increase this Patient’s risk of unintended pregnancy this is not advisable to her.

Switching the patient to a copper intrauterine device (IUD) will decrease systemic side effects, but as its inflammatory reaction in the uterus may increase pain symptoms, copper IUD is not recommended for patients with dysmenorrhea.

As Medroxyprogesterone will increase body fat and decrease lean muscle mass resulting in weight gain is not a good option for this patient. Also medroxyprogesterone due to its risk of significant loss of bone mineral density, is not recommended for adolescents or young women. So it can be used in this age group only if other options are unacceptable.

Presence of estrogen component is the main reason behind the side effects of combination OCPs. Progesterone-only pills have relatively fewer side effects but as they do not inhibit ovulation, they are less effective for treating dysmenorrhea and for contraception.

Combination oral contraceptive pills are the first-line therapy for primary dysmenorrhea in sexually active patients.  Its side effects include breakthrough bleeding, hypertension, and increased risk of venous thromboembolism. Researches proves that weight gain is usually not an adverse effect of OCPs.

The partial mole is produced when an egg is fertilized by two sperm producing genotype 69 XXY (triploid). It can also occur when one sperm reduplicates itself yielding the genotypes 92 XXXY (tetraploid) though this is less common The genotype of a complete mole is typically 46 XX (diploid) but can also be 46 XY (diploid)

Involution of the uterus takes 4-6 weeks

This is a grade 1 prolapse

With increasing maternal age, the risk of miscarriage increases. For women between the ages of 40-44, the miscarriage rates sit at about 50% and increases to over 75% for women 45 years and over. The miscarriage rate for women between the ages of 35-39 is 25%.

With the help of molding, the fetal head changes its shape as the skull bones overlap. This helps in smooth delivery of the foetus through the birth canal.

Uterine surgical history & scope of vaginal birth are as follows:
– In case of low transverse cesarean delivery with horizontal incision: trial of labor is not contraindicated.
– Classical cesarean delivery with vertical incision: trial of labor is contraindicated
– Abdominal myomectomy with uterine cavity entry: trial of labor is contraindicated
– Abdominal myomectomy without uterine cavity entry: trial of labor is not contraindicated.

In laboring patients with prior uterine surgical histories like a prior classical (vertical) cesarean delivery or a prior myomectomy that was extensive or has entered the uterine cavity like during removal of intramural or submucosal fibroids are at a higher risk for uterine rupture. Given this patient’s history of previous myomectomy, her intense and constant abdominal pain with an abnormal fetal heart rate tracing, like persistent variable decelerations, are pointing to uterine rupture. vaginal bleeding, abdominally palpable fetal parts, loss of fetal station and any change in contraction pattern are the other possible manifestations of uterine rupture. Based on the extent and exact location of the rupture and the presence or absence of regional anesthesia, presentation of a uterine rupture will change.

Vaginal delivery is safe after a low transverse (horizontal uterine incision) cesarean delivery. Patients with a history of either classical cesarean delivery or an extensive myomectomy are delivered via cesarean delivery at 36-37 weeks gestation, so urgent laparotomy and cesarean delivery are required if these patients present in labor. Further management is determined by other intraoperative findings like, whether uterine rupture has occurred, if occured then delivery is done through the rupture site, followed by a uterine repair; If the uterus is unruptured, a hysterotomy (ie, cesarean delivery) is performed. In patients with prior classical cesarean delivery or extensive myomectomy, an expectant management for a vaginal delivery is contraindicated.

Amnioinfusion is the technique of placing an intrauterine pressure catheter to decrease umbilical cord compression by doing an intrauterine infusion and this thereby helps to resolve variable decelerations. In patients with a history of uterine surgery Amnioinfusion is contraindicated.

In cases with abnormal fetal heart rate tracings, if the patient is completely (10cm) dilated, an operative vaginal delivery can be performed to expedite a vaginal delivery.

Terbutaline is a tocolytic, which is administered to relax the uterus in conditions with contractile abnormalities, such as tachysystole which presents with >5 contractions in 10 minutes or tetanic contractions were contractions last for >2 minutes, which results in fetal heart rate abnormalities. In the given case, the patient’s contractions are normal, which occurs in every 2-3 minutes and lasts for 45 seconds, causing pain and cervical dilation.

After a classical cesarean delivery or an extensive myomectomy, labor and vaginal delivery are contraindicated due to its significant risk of uterine rupture. Laparotomy and cesarean delivery are preferred in laboring a patients at high risk of uterine rupture.

The risk factors for uterine carcinoma include obesity, diabetes, Nulliparity, late menopause, unopposed oestrogen therapy, tamoxifen therapy, HRT and a family history of ovarian or uterine carcinoma.

Endocrine hormones are released from their site of origin and travel through the blood to act on other distant target organs. Autocrine hormones act within the same cell and exocrine glands secrete their products into ducts.

Mitral stenosis is the most common cardiac condition affecting women during pregnancy and is poorly tolerated due to the increased intravascular volume, cardiac output and resting heart rate that predictably occur during pregnancy.

Young women may have asymptomatic mitral valve disease which becomes unmasked during the haemodynamic stress of pregnancy. Rheumatic mitral stenosis is the most common cardiac disease found in women during pregnancy. The typical increased volume and heart rate of pregnancy are not well tolerated in patients with more than mild stenosis. Maternal complications of atrial fibrillation and congestive heart failure can occur, and are increased in patients with poor functional class and severe pulmonary artery hypertension.

Folate has been in the news because of its connection with a type of birth defect called neural tube defect. Studies have shown that women who have infants with neural tube defects have lower intakes of folate and lower blood folate levels than other women. Folate is needed early in pregnancy (before many women know they are pregnant) for normal neural tube development.

Many vegan foods including enriched bread, pasta, and cold cereal; dried beans; green leafy vegetables; and orange juice are good sources of folate. Vegan diets tend to be high in folate, however, to be on the safe side, women capable of becoming pregnant should take a supplement or use fortified foods that provide 400 micrograms of folate daily.

For the above mentioned reasons, all other options are incorrect.

The most probable cause of her presentation is a mixed infection with Chlamydia trachoma and vaginal pathogens.

Her most likely diagnosis is pelvic inflammatory disease (PID) as suggested by a purulent vaginal discharge alongside a fever which indicates a systemic infection.

The most common causative organisms in PID after sexual activity are chlamydia and gonorrhoea, of which chlamydia has a much higher prevalence.

Chlamydia has also been shown to be present in about 15% of subjects who underwent pregnancy termination with no constant sexual partner.

PID occurring after a gynaecologic surgical procedure is most commonly a result of mycoplasma or vaginal pathogens.

Endometritis is inflammation of the inner lining of the uterus (endometrium). Symptoms may include fever, lower abdominal pain, and abnormal vaginal bleeding or discharge. It is the most common cause of infection after childbirth. The intermittent vaginal bleeding and the requirement for manual removal of the placenta suggest endometritis as the most possible diagnosis.
