The patient most likely suffered a uterine rupture. It occurs most often in multiparous women and is less often associated with external haemorrhage. Shock develops shortly after rupture due to the extent of concealed bleeding.

Uterine inversion rarely occurs when after a spontaneous and normal third stage of labour. Although it can lead to shock, it is usually associated with a history of controlled cord traction or Dublin method of placenta delivery before the uterus has contracted. This diagnosis is also strongly considered when shock is out of proportion to the amount of blood loss.

An overwhelming infection is unlikely in this case when labour occurred for a short period of time. Uterine atony and amniotic fluid embolism are more associated with excessive vaginal bleeding, which is not evident in this case.

During follicular phase, there is an increase in gonadotrophin hormones and a proliferation of the endometrium occurs. The duration of the cycle depends upon the overall length of the menstrual cycle. The progesterone levels are increased in the luteal phase and not in follicular phase.

In pregnancy, the uterus increases in size to accommodate the developing foetus. At 16 weeks gestation, the fundus of the uterus must be palpated at the midpoint between the umbilicus and the pubic symphysis but the patient’s uterus was already palpable at just 11 weeks.

If less than seven weeks pregnant, it’s unlikely to find a heartbeat by ultrasound. Using transvaginal ultrasound, a developing baby’s heartbeat should be clearly visible by the time a woman is seven weeks pregnant. Abdominal ultrasound is considerably less sensitive, so it can take longer for the heartbeat to become visible. If past seven weeks pregnant, seeing no heartbeat may be a sign of miscarriage.

Fetal viability is confirmed by the presence of an embryo that has cardiac activity. Cardiac activity is often present when the embryo itself measures 2 mm or greater during the 6th week of gestation. If cardiac activity is not evident, other sonographic features of early pregnancy can predict viability.

It is recommended that all pregnant women undergo a routine ultrasound at 10 to 13 weeks of gestation to determine an accurate gestational age. Getting an accurate gestational age is highly important and pertinent for the optimal assessment of fetal growth later in pregnancy. Ultrasound is the most reliable method for establishing a true gestational age by measurement of crown-rump length, which can be measured either transabdominally or transvaginally.

Atosiban is a modified form of oxytocin that is administered by intravenous infusion for 2–48 hours.

Cord entanglement, a condition unique to MoMo pregnancies, occurs in 42 to 80% of the cases and it has been traditionally related to high perinatal mortality. Umbilical cord entanglement is present in all monoamniotic twins when it is systematically evaluated by ultrasound and colour Doppler. Perinatal mortality in monoamniotic twins is mainly a consequence of conjoined twins, twin reversed arterial perfusion (TRAP), discordant anomaly and spontaneous miscarriage before 20 weeks’ gestation. Expectantly managed monoamniotic twins after 20 weeks have a very good prognosis despite the finding of cord entanglement. The practice of elective very preterm delivery or other interventions to prevent cord accidents in monoamniotic twins should be re-evaluated.

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.

Pregnancy is the most common cause of secondary amenorrhea worldwide. As a result, the first thing to check in every woman of reproductive age who has amenorrhea is a urine pregnancy test.
Once pregnancy has been ruled out, an ultrasound or measuring FSH and LH may be done to assess the condition (if required).
FBC is used to track clozapine side effects such as neutropenia and agranulocytosis. It is not recommended for the assessment of amenorrhea.

The basic components of the mammary gland are the alveoli. These are lined with milk-secreting cuboidal cells surrounded by myoepithelial cells. The alveoli join to form groups known as lobules. The lobules form lobes. Each lobe has a lactiferous duct that drains into openings in the nipple. Each breast typically contains 15-20 lobes.

The half-life of lidocaine is approximately 1.5 hours. It is a local anaesthetic and the maximum dose that can be given is 3mg/kg.

Endometrial hyperplasia with atypia is at high risk of progression to cancer and hysterectomy is indicated There is high risk of progression to cancer with endometrial hyperplasia with atypia and hysterectomy is indicated. Although weight loss would be beneficial this shouldn’t delay surgical management.

Activation of Antithrombin III and inactivation of factor Xa is the primary mechanism of action of Heparin.

An underlying disease is only found in 17 % of cases in mild polyhydramnios. In contrast, an underlying disease is detected in 91 % of cases in moderate to severe polyhydramnios. The literature lists the following potential aetiologies: fetal malformations and genetic anomalies (8–45 %), maternal diabetes mellitus (5–26 %), multiple pregnancies (8–10 %), fetal anaemia (1–11 %), other causes, e.g. viral infections, Bartter syndrome, neuromuscular disorders, maternal hypercalcemia. Viral infections which can lead to polyhydramnios include parvovirus B19, rubella, and cytomegalovirus. Other infections, e.g. toxoplasmosis and syphilis, can also cause polyhydramnios.

Before considering invasive procedures, a cervical smear must first be performed. Antibiotics can only be given when inflammation has been confirmed and culture results have identified the organism causing the inflammation. Endometrial ablation, colposcopy and vaginal US are all invasive procedures that are not relevant in the immediate management of this patient.

Vulvovaginal candidiasis is the most common genital infection and it is caused by candida albicans in 80-92% of the cases. Other non albicans species include C.tropicalis, C.glabrata, C.krusei and C.parapsilosis. 20% of women of childbearing age are asymptotic colonisers of Candida species as part of their normal vaginal flora. This increases to 40% in pregnancy.

The incubation period of rubella is 12-23 days.

The Rubella virus, also known as German measles, is found in the Togavirus family and is a single-stranded RNA virus. The virus, which is acquired through contact with respiratory secretions, primarily replicates in the nasopharynx and lymph nodes, and produces a mild and self-limiting illness. Congenital infection, however, is associated with several anomalies including sensorineural deafness, cataracts and cardiac abnormalities.

The case presented points to a diagnosis of an autoimmune thyroiditis leading to hypothyroidism. The most common form of autoimmune hypothyroidism, Hashimoto’s, often presents with a goitre, positive for antibody tests against thyroid components i.e. anti-TPO and anti-thyroglobulin. Graves disease and toxic diffuse goitre are more likely to cause hyperthyroidism. While De-Quervain’s and endemic goitre may cause hypothyroidism, they don’t result in positive antibody tests.

Breech presentation refers to the foetus in the longitudinal lie with the buttocks or lower extremity entering the pelvis first.

Clinical conditions associated with breech presentation include those that may increase or decrease fetal motility, or affect the vertical polarity of the uterine cavity. Prematurity, multiple gestations, aneuploidies, congenital anomalies, Mullerian anomalies, uterine leiomyoma, and placental polarity as in placenta previa are most commonly associated with a breech presentation. Also, a previous history of breech presentation at term increases the risk of repeat breech presentation at term in subsequent pregnancies.

Conditions that change the vertical polarity or the uterine cavity, or affect the ease or ability of the foetus to turn into the vertex presentation in the third trimester include:
– Mullerian anomalies
– Placentation
– Uterine leiomyoma
– Prematurity
– Aneuploidies and fetal neuromuscular disorders
– Congenital anomalies
– Polyhydramnios and oligohydramnios
– Laxity of the maternal abdominal wall.

Endometriosis is found in about one-third of women undergoing laparoscopy for chronic pelvic pain. Published studies show a diagnostic delay of 8.5 years from onset of symptoms to the eventual diagnosis of endometriosis!

This means that women can suffer for 8.5 years before a diagnosis of endometriosis is made, and appropriate interventions are carried out.

All other options are true statements about endometriosis.

Functional closure of the ductus arteriosus is neonates is completed within the first few days after birth. It normally occurs by the 12th postnatal week. It has been suggested that persistent patency of DA results from a failure of the TGF-B induction after birth. Due to increased arterial pO2, constriction of the DA occurs. In addition to this on inflation the bradykinin system is activated with cause the smooth muscles in the DA to constrict. A decrease in the E2 prostaglandin is also an important factor as raised levels have been indicated in keeping the patency of the DA.

Ectopic pregnancies can quickly become a gynaecological emergency if left untreated. The majority of ectopic pregnancies (95-97%) are tubal occurring in the fallopian tube as opposed to the abdomen, ovary or cervix. In tubal ectopics, the most common site of occurrence is in the ampulla (70%), followed by the isthmus, fimbria, and the cornua.

The right ovarian vein ascends and enters the inferior vena cava and the left ovarian vein drains into the longer left renal vein.

Genital herpes can be asymptomatic or have mild symptoms that go unrecognized. When symptoms occur, genital herpes is characterised by one or more genital or anal blisters or ulcers. Additionally, symptoms of a new infection often include fever, body aches and swollen lymph nodes.

HSV-2 is mainly transmitted during sex through contact with genital or anal surfaces, skin, sores or fluids of someone infected with the virus. HSV-2 can be transmitted even if the skin looks normal and is often transmitted in the absence of symptoms.

In rare circumstances, herpes (HSV-1 and HSV-2) can be transmitted from mother to child during delivery, causing neonatal herpes. Neonatal herpes can occur when an infant is exposed to HSV during delivery. Neonatal herpes is rare, occurring in an estimated 10 out of every 100 000 births globally. However, it is a serious condition that can lead to lasting neurologic disability or death. The risk for neonatal herpes is greatest when a mother acquires HSV for the first time in late pregnancy.

Contraindications to tocolysis in preterm labor are as follows:
– Gestational age > 34 weeks or <24 weeks
– Labor is too advanced with an advanced cervical dilation of >4 cm
– Abnormal CTG suggesting a non-reassuring fetal status
– Lethal fetal anomalies
– Intrauterine fetal demise
– Suspected fetal compromise
– Significant antepartum hemorrhage, such as placental abruption/ active vaginal bleeding with hemodynamic instability
– Any suspected intrauterine infections like chorioamnionitis
– Maternal hypotension
– Pregnancy-induced hypertension/ eclampsia/ pre-eclampsia
– Placenta previa
– Placental insufficiency
– Intrauterine growth retardation
– Maternal allergy to specific tocolytic agents or cases where tocolytics are contraindicated due to specific comorbidities like in case of cardiac disease, were beta agonists cannot be administered.

As there are nonpulmonary morbidities associated with preterm birth, fetal pulmonary maturity, known or suspected, is not an absolute contraindication for tocolysis. These fetuses could potentially benefit from prolongation of pregnancy and from the nonpulmonary benefits of glucocorticoid therapy.

When cervical dilation is greater than 3 cm inhibition of preterm labor is less likely to be successful. In such cases Tocolysis can be considered when the goal is to administer antenatal corticosteroids or to safely transport the mother to a tertiary care center.

Maternal hypothyroidism which is usually treated with thyroxine is not a contraindication to suppression of labor.

Atenolol is considered teratogenic and has two main risks: fetal bradycardia and neonatal apnoea. ACE inhibitors and angiotensin II receptor blockers are also known to be teratogenic (even though large-scale studies are difficult to conduct during pregnancies).

minutes, for a maximum of three dosages or until BP < 160/110mmHg (contraindication:
tachycardia > 120 bpm, unable to swallow, cardiac lesion).
• If after 30 minutes BP is still high then give Labetalol 20, 40, 80, 80 and
80mg (max 300mg) as bolus doses at 10 minute intervals, checking BP every 10
minutes until BP < 160/110mmHg. Contra-indications: patients with asthma and
ischaemic heart disease. If BP monitoring is not achievable at 10 minute intervals then
patient should be transferred to ICU for a Labetalol infusion.

Vaginal atrophy (thinning of vaginal tissue): Oestrogen helps to keep this tissue healthy. After menopause, low oestrogen levels can cause your vaginal walls to become thin, dry, and inflamed. That often leads to bleeding after sex.

Vaginal atrophy is the most common cause of post menopausal vaginal bleeding.

With a normal pap smear a year ago, this patient is unlikely to develop cervical cancer.

Cervical ectropions are not common in post-menopausal women.

Endometrial cancer and cervical polyps are possible causes of postcoital bleeding, however, they are not as common as vaginal atrophy.

HELLP syndrome stands for haemolysis, elevated liver enzyme levels, and low platelet levels and is a very severe condition that can happen during pregnancy. Management of this condition requires immediate delivery of the baby.

Functional Hypothalamic Amenorrhea (FHA) is a form of chronic anovulation, due to non-identifiable organic causes and often associated with stress, weight loss, excessive exercise, or a combination thereof. Investigations should include assessment of systemic and endocrinologic aetiologies, as FHA is a diagnosis of exclusion. A multidisciplinary treatment approach is necessary, including medical, dietary, and mental health support. Medical complications include, among others, bone density loss and infertility.

Erb’s or Erb-Duchenne palsy is a type of brachial plexus injury. The brachial plexus comprises C5 to T1 nerve roots. In Erb’s palsy C5 and C6 are the roots primarily affected. Shoulder Dystocia is the most common cause of Erb’s palsy.

A pH value below than 7.18 indicates acidosis which can result in hypoxic brain injury. In order to prevent brain injury, immediate delivery of the foetus should be planned. The normal range for a term baby is pH: 7.18 – 7.38, preterm pH: 7.14 – 7.4.
