The right ovarian vein travels through the suspensory ligament of the ovary and generally joins the inferior vena cava whereas the left ovarian vein drains into the left renal vein.

This woman presents with a metastatic tumour of the ovary. Being from Australia is a hint in this question as the likely site of the primary tumour can vary depending on the country the patient is in and the availability of screening mammography. In underdeveloped countries, breast cancer is usually diagnosed later in life as screening mammography is generally not available, making the most likely site of the primary tumour in the breast. In Japan, where the incidence of stomach cancer is much higher than in western countries, the most likely primary site would be the stomach with a Krukenberg tumour in both ovaries. In Australia, mammographic screening is recommended every other year for all women over the age of 50, and so the most likely primary site would be the colon.

The most appropriate work-up to find the primary tumour in this patient would be performing a colonoscopy. A computed tomography (CT) of the abdomen may miss a small tumour, and an ultrasound examination would not be able to diagnosis a colon cancer. Mammography would be the correct response in under-developed countries. A lung malignancy would be detectable by chest X-ray, but would rarely cause a metastasis in the ovary.

In hyperemesis gravidarum, IV corticosteroids can be given to reduce vomiting, if the patient is not responding to standard anti emetics.

Sheehan syndrome is the pregnancy related infarction of the pituitary gland. During pregnancy the gland doubles in size but the blood supply does not increase significantly and during delivery due to the loss of blood it principates infarction. This results in fatigue, poor lactation and loss of pubic hair.

Ureters are muscular tubes that run from the kidneys to the urinary bladder. It is lined by transitional epithelium.

Syntocin 5u by slow intravenous injection is the first line pharmacological measurement in this scenario

The commonest foetal presentation in twin pregnancy is cephalic-cephalic.

If one believes that this cycle will last 35 days, the cyst in the left ovary was discovered at mid-cycle.
It’s too huge to be a ruptured pre-ovulatory follicle, and it doesn’t exhibit the characteristics of a corpus luteum, a benign cystic teratoma, or an endometrioma.

As a result, a follicular cyst is the most likely diagnosis.

A benign cyst is almost always seen on ultrasound as a unilocular, thin-walled cystic formation.

The presence of solid materials in a multiloculated cystic structure strongly suggests the presence of a malignant mass.
In a 25-year-old woman, this would be unusual, but not unheard of.

Shoulder dystocia occurs when the anterior or posterior fetal shoulder impacts on the maternal symphysis or sacrum and may require additional manevours to release the shoulders after gentle downward traction has failed. The most common injury that can occur, is to the brachial plexus due to lateral flexion of the head during traction. This may cause a neurological disability, Erb’s Palsy ( injury to C5 and C6 of the brachial plexus) in which there is a less than 10% chance that this injury would be permanent.

There is an association between 20 to 30% increase in the risk for developing pyelonephritis during later pregnancy and untreated cases of bacteriuria in pregnancy. This is due to the physiological changes occurring to urinary tract during pregnancy, it is also found that untreated bacteriuria can be associated with even preterm birth and low birth weight. Risk of symptomatic urinary tract infection (UTI) during pregnancy can be reduced by antibiotic treatment of asymptomatic bacteriuria

The most common pathogen associated with asymptomatic bacteriuria is Escherichia coli, which accounts to more than 80% of isolates and the second most frequently cultured uropathogen is Staphylococcus saprophyticus. Other Gram-positive cocci, like group B streptococci, are less common. Gram-negative bacteria such as Klebsiella, Proteus or other Enterobacteriaceae are the other organisms involved in asymptomatic bacteriuria.

Although the context patient is asymptomatic, her urine dipstick shows positive nitrite and leukocyte, suggestive of urinary tract infection, so oral antibiotics like cephalexin or nitrofurantoin are advisable. Normally a five day course of oral antibiotic will be sufficient for the treatment of uncomplicated UTI or asymptomatic bacteraemia in pregnant women. As the patient is currently at her 38 weeks of gestation nitrofurantoin is contraindicated so it is best to prescribe her with Oral Cephalexin. This is because nitrofurantoin is associated with an increased risk of neonatal jaundice and haemolytic anaemia, so should not be used close to delivery, that is after 37 weeks of gestation or sooner if early delivery is planned.

Acute pyelonephritis should be treated with Intravenous antibiotic treatment, guided by urine culture and sensitivity reports as soon a available. A course of minimum of 10-14 days with IV + oral antibiotics is recommended as treatment for pyelonephritis, along with an increased fluid intake as intravenous fluids in clinically dehydrated patients. Even though urinary alkalisers are safe in pregnancy, prescription of urinary alkalisers alone is not recommended due to its low effectiveness compared to antibiotics, also as it can result in a loss of treatment efficacy urinary alkalisers should never be used in combination with nitrofurantoin.

At any stage of pregnancy, if Streptococcus agalactiae, a group B streptococcus [GBS], is detected in urine the intrapartum prophylaxis for GBS is usually indicated.

Hysterosalpingography is used to assess the patency of the fallopian tubes. It is performed by injection of a radio-opaque iodine based contrast. This test is contraindicated in pelvic inflammatory disease and during pregnancy. Should be performed in Follicular phase of menstrual cycle after cessation of menstrual bleeding and prior to ovulation (days 6-12).

This is a case of a pregnant patient having vaginal bleeding. Given the patient’s presentation, the most likely cause of this patient’s antepartum haemorrhage is placenta praevia. The haemorrhage is unlikely to be due to a vasa praevia because a loss of 300mL would usually cause fetal distress or death, neither of which has occurred. Cervical malignancy is also unlikely as it typically would not have bleeding of this magnitude. A possible diagnosis would be a small placental abruption as it would fit with the lack of uterine tenderness and normal uterine size.

For the immediate management of this patient, induction of labour is contraindicated before the placental site has been confirmed. Also, induction should not be performed when the gestation is only at 33 weeks, especially after an episode of a small antepartum haemorrhage. An ultrasound examination of the uterus is appropriate as it would define whether a placenta praevia is present and its grade. It would also show whether there is any evidence of an intrauterine clot associated with placental abruption from a normally situated placenta.

If a placenta praevia is diagnosed by ultrasound, a pelvic examination under anaesthesia may be a part of the subsequent care, if it is felt that vaginal delivery might be possible. Usually it would be possible if the placenta praevia is grade 1 or grade 2 anterior in type. However, pelvic exam at this stage is certainly not the next step in care, and is rarely used in current clinical care.

A Papanicolaou (Pap) smear will be necessary at some time in the near future, but would not be helpful in the care of this patient currently.

Immediate Caesarean section is not needed as the bleeding has stopped, the foetus is not in distress, and the gestation is only 33 weeks.

Gonorrhoea is a sexually transmitted diplococcus bacteria known to infect the female genital tract, which can cause an ascending infection in the uterus and fallopian tubes. About 15 percent of women with this infection may develop pelvic inflammatory disease (PID), which poses risks of long term consequences: ectopic pregnancy, infertility and chronic pelvic pain.

The ovarian arteries are considered the main blood supply for the ovaries. The ovarian arteries usually arise from the lateral aspect of the abdominal artery, though in some instances they may arise from the renal or iliac arteries.

Achieving spontaneous pregnancy is rare in cases where a couple have been infertile with abnormal semen analysis (count <5million/mL and reduced motility), hence there is generally an indication for treatment. FSH injection usually would not be expected to improve the semen specimen. Rate of pregnancy would be much lower if at the time of intrauterine insemination, the total motile count is less 5 million. In this case, his count is 1 million. Pregnancy is likely to be achieved with donor sperm but as it would not contain the husband’s genetic material, it would be only considered later on once all other methods involving his own sperm have failed. Out of all the options, IVF would most likely result in a pregnancy, in which it allows the husband’s sperm to spontaneously fertilise the oocyte. Rate of pregnancy would roughly be 2% per treatment cycle. This rate would increase to roughly 20% if ISCI is also used.

The arcuate line is a smooth rounded border on the internal surface of the ilium just inferior to the iliac fossa. It forms the boundary of the pelvic inlet.

This infant will most likely be diagnosed as having fetal hydantoin syndrome, which occurs due to an in utero exposure to antiepileptic drugs like phenytoin, carbamazepine, valproate etc. 

Multiple antiepileptics, due to their ability to cross placenta, have teratogenic effects which will result in low folate and high oxidative metabolite levels in the fetus. This likely combined effect results deformities like cleft lip and palate, wide anterior fontanelle, distal phalangeal hypoplasia and cardiac anomalies like pulmonary stenosis, aortic stenosis etc in the fetus. There will be developmental delay and poor cognitive outcomes as a result of neural tube defects and microcephaly associated with this. Therefore, prior to conception, those patients who require antiepileptics for seizure control during pregnancy should titrate it to the lowest dose and must started on high-dose (4 mg) folic acid supplementation to minimize the risk of such congenital malformations.

Fetal alcohol syndrome commonly presents with microcephaly and midfacial hypoplasia, but is not association with cleft lip or palate.

Cocaine use during pregnancy can be associated with preterm delivery, abruptio placentae and fetal growth restriction; but there is no evidence to prove its association with congenital defects.

Fetal renal failure with associated oligohydramnios that results in pulmonary hypoplasia, growth restriction, and limb defects are the complications associated with the use of lisinopril and other angiotensin-converting enzyme inhibitors during pregnancy; but it does not cause cleft lip or palate.

Most infants with congenital syphilis are asymptomatic at birth and those with symptoms typically have rhinitis or “snuffles, hepatomegaly and a maculopapular rash none of which are seen in this patient.

Fetal hydantoin syndrome results from the in-utero exposure to antiepileptic drugs like phenytoin, carbamazepine etc and is usually presented with microcephaly, a wide anterior fontanelle, cleft lip and palate, and distal phalangeal hypoplasia.

Abdominal hysterectomy is performed through a Pfannenstiel incision. There are certain complications associated with hysterectomy including haemorrhage, injury to the ureter(1%) and less commonly bladder and bowel (0.04%).

Testing for beta hCG should be the first test in this case. It will rule out any pregnancy that is strongly suspected based on the patient’s history and physical examination.

Absolute contraindications to OCs include breast cancer, history of deep venous thrombosis or pulmonary embolism, active liver disease, use of rifampicin, familial hyperlipidaemia, previous arterial thrombosis, and pregnancy, while relative contraindications include smoking, age over 35, hypertension, breastfeeding, and irregular spontaneous menstruation.

Progestin only pills are the safest and most effective contraceptive methods than the rest of the options.

Promethazine or Cyclizine are 1st choice options for management of nausea and vomiting in pregnancy according to NICE. Prochlorperazine is also appropriate 1st line.

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.

FVS has been reported to complicate maternal chickenpox that occurs as early as 3 weeks and up to 28 weeks of gestation. The risk appears to be lower in the first trimester (0.55 per cent). No case of FVS has been reported when maternal infection has occurred after 28 weeks.

The Conjoint tendon AKA Inguinal falx reinforces the posterior wall of the inguinal canal. The inguinal and lacunar ligaments are part of the floor The aponeurosis of external oblique is the major component of the anterior wall with fibres of internal oblique reinforcing the lateral part

Sodium Valproate is known to be the most teratogenic when used in the first trimester of pregnancy. This antiepileptic increases the risk of congenital malformations including a 10-20 fold risk of neurodevelopmental defects. Though the use of antiepileptics should generally be avoided during pregnancy, carbamazepine, or newer drugs such as Lamotrigine are thought to carry less of a risk of teratogenicity.

Women with medical conditions associated with increased risk for thrombosis generally should not use oestrogen-containing contraceptives.

The majority of evidence identified does not suggest an increase in odds for venous or arterial events with use of most POCs. Limited evidence suggested increased odds of VTE with use of injectables (three studies) and use of POCs for therapeutic indications (two studies, one with POCs unspecified and the other with POPs).

Discontinuing anticoagulants increases her risk of recurrent DVT.

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.

This patient had postmenopausal vaginal haemorrhage and an 8mm endometrial thickness. Endometrial thickness of 4mm or more in a postmenopausal woman with vaginal bleeding necessitates an endometrial biopsy to rule out endometrial cancer, and this patient should be referred to a gynaecologist for this procedure.
All of the other choices are incorrect.

An LSIL Pap test shows mild cellular changes. The risk of a high-grade cervical precancer or cancer after an LSIL Pap test is as high as 19 percent.

As with an ASC-US Pap test, an LSIL Pap test is evaluated differently depending upon age. For women ages 25 or older, follow-up depends upon the results of human papillomavirus (HPV) testing:

– Women who test positive for HPV or who have not been tested for HPV should have colposcopy.
– Women who test negative for HPV can be followed up with a Pap test and HPV test in one year.

Referral to an oncologist is not necessary since there is no established diagnosis of malignancy. All other options are unacceptable.

Ovarian insufficiency is a failure of the ovary to function adequately in a woman younger than 40 years, in its role either as an endocrine organ or as a reproductive organ. In women aged 40 years or older, the expected physiologic decline of ovarian function that takes place with aging is termed perimenopause or the menopausal transition.
Medical treatment of patients with primary ovarian insufficiency should address the following aspects:

Ovarian hormone replacement
Restoration of fertility
Psychological well-being of the patient

It is not appropriate to give this patient contraceptive pills since she desires pregnancy.

There is no evidence that Danazol or Metformin would improve ovarian follicle function.

HB gower 1 is the predominant embryonic haemoglobin when the foetus is 6 weeks old and is replaced by adult haemoglobin by the age of 5 months post natally.

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.

The Vaginal artery, like the Uterine artery is typically a branch of the Internal Iliac artery. It can sometimes arise as a branch of the Uterine artery so it is important to read the question (if the stem stated it CAN arise from the Uterine artery then that would be true)

Tetracycline is a broad-spectrum antibiotic that crosses placental barrier. Tetracycline was the first line of therapy in treating infections caused by Mycoplasma pneumoniae, chlamydia, rickettsia, and some spirochaetes. It has a wide range of adverse effects and is known for a unique property of being incorporated into skeletal and dental tissues at sites of active mineralization and staining of these tissues.

Maternal exposure to dietary factors during pregnancy can influence embryonic development and may modulate the phenotype of offspring through epigenetic programming. Folate is critical for nucleotide synthesis, and preconceptional intake of dietary folic acid (FA) is credited with reduced incidences of neural tube defects in infants.

This patient most likely has preeclampsia, which is defined as an elevated blood pressure and proteinuria after 20 weeks gestation. The patient needs further evaluation, including a 24-hour urine for quantitative measurement of protein, blood pressure monitoring, and laboratory evaluation that includes haemoglobin, haematocrit, a platelet count, and serum levels of transaminase, creatinine, albumin, LDH, and uric acid- A peripheral smear and coagulation profiles also may be obtained- Antepartum fetal testing, such as a nonstress test to assess fetal well-being, would also be appropriate.

→ Ultrasonography should be done to assess for fetal intrauterine growth restriction, but only after an initial laboratory and fetal evaluation.
→ It is not necessary to start this patient on antihypertensive therapy at this point. An obstetric consultation should be considered for patients with preeclampsia.
→ Delivery is the definitive treatment for preeclampsia- The timing of delivery is determined by the gestational age of the foetus and the severity of preeclampsia in the mother. Vaginal delivery is preferred over caesarean delivery, if possible, in patients with preeclampsia.

Congenital rubella infection that occurs after 16 weeks gestation does not typically cause fetal abnormalities. This however plays no part in vaccination advice. Rubella vaccine is live and should not be given during pregnancy. The mother should be offered vaccination after giving birth. It is safe for the vaccine (typically given as combined MMR) to be administered if the mother is breastfeeding.

WHO defines perinatal death as the number of still births and death in the first week of life per 1000 births.

Condition where there is insufficient fetal descent after pushing for ≥3 hours in nulliparous and ≥2 hours if multiparous women is defined as Second stage arrest of labor. Common risk factors for this presentation are maternal obesity, excessive weight gain during pregnancy and diabetes mellitus. Cephalopelvic disproportion, malposition, inadequate contractions and maternal exhaustion are the common etiologies of Second stage arrest of labor. Management includes Operative vaginal delivery or cesarean delivery as indicated in the case.

The second stage of labor begins with the dilatation of cervix to 10 cm and will end with fetal delivery. Parity and use of neuraxial anesthesia are the two factors which will affect the duration of second stage of labor and fetal station, which measures the descent of the fetal head through the pelvis determines its progression.

When there is no fetal descent after pushing for ≥3 hours or ≥2 hours in in nulliparous and multiparous patients respectively the condition is called an arrested second stage of labor. As her first delivery was a cesarean session due to breech presentation, this patient in the case is considered as nulliparous.

Most common cause of a protracted or arrested second stage is fetal malposition, which is the relation between the fetal presenting part to the maternal pelvis. Occiput anterior is the optimal fetal position as it facilitates the cardinal movements of labor, any deviations from this position like in occiput transverse position, can lead to cephalopelvic disproportion resulting in second stage arrest.
Inadequate contractions, that is less than 200 MVU averaged over 10 minutes, can lead to labor arrest but contractions are adequate in case of the patient mentioned.
Second stage arrest can be due to maternal obesity and excessive weight gain during pregnancy but this patient had a normal pre-pregnancy BMI of 20 kg/m2 and an appropriate weight gain of 15.9 kg 35 lb. So this also cannot be the reason.

Maternal expulsive efforts will change the fetal skull shape. This process called as molding helps to facilitate delivery by changing the fetal head into the shape of the pelvis. Whereas prolonged pressure on head can result in scalp edema which is called as caput, presence of both molding and caput suggest cephalopelvic disproportion, but is not suggestive of poor maternal effort.

Patients with a prior history of uterine myomectomy or cesarean delivery are at higher risk for uterine rupture.  In cases of uterine rupture, the patient will present with fetal heart rate abnormalities, sudden loss of fetal station (eg, going from +1 to −3 station) along with fetal retreat upward and into the abdominal cavity through the uterine scar due to decreased intrauterine pressure. In the given case patient’s fetal heart rate tracing is category 1 and fetal station has remained 0 which are non suggestive of uterine rupture.

When there is insufficient fetal descent after pushing ≥3 hours in nulliparous patients or ≥2 hours in multiparous patients is considered as second stage arrest of labor. The most common cause of second stage arrest is cephalopelvic disproportion, were the fetus presents in a nonocciput anterior position called as fetal malposition.

Indications for FBS:
1. Pathological CTG in labour (cervix dilated >3 cm)
2. Suspected acidosis in labour (cervix dilated >3 cm)
Contraindications to FBS:
– Maternal infection e.g. HIV, HSV and Hepatitis
– Known fetal coagulopathy
– Prematurity (< 34 weeks gestation)
– Acute fetal compromise

Cystic fibrosis is the most common fetal genetic disease in Caucasians and has an autosomal recessive inheritance. It is caused by an abnormal chloride channel due to a defect in the CFTR gene. Complications range from haemoptysis, respiratory failure, biliary cirrhosis, diabetes and male infertility. Men with CF are infertile in 98% of the cases due to failure of development of the vas deference.

The 3 main oestrogens are Estrone (E1) Oestradiol (E2) and Estriol (E3). Oestradiol is the predominant oestrogen during female reproductive years except during the early follicular phase when Estrone predominates. During pregnancy Estriol levels rise significantly and this becomes the dominant oestrogen during pregnancy. Ethinylestradiol and Mestranol are oestrogen found in COCP’s

Disseminated intravascular coagulation (DIC) in pregnancy is the most common cause of an abnormal haemorrhage tendency during pregnancy and the puerperium. Although pregnancy itself can cause DIC, its presence is invariably evidence of an underlying obstetric disorder such as abruptio placentae, eclampsia, retention of a dead foetus, amniotic fluid embolism, placental retention or bacterial sepsis.

The Rhesus status of a mother is important in pregnancy and even abortion. The exposure of an Rh-negative mother exposed to Rh antigens from a positive foetus, will influence the development of anti-Rh antibodies. This may cause problems in subsequent pregnancies leading to haemolysis in the newborn. Rh Anti RhD- globulin is therefore given to non-sensitised Rh-negative mothers who give birth to Rh-positive children to prevent the formation of anti-Rh antibodies. Anti RhD globulin is not useful for already sensitized, or RhD positive mothers; its administration could result in maternal blood being bound and taken out of circulation.

It is usual to experience heavy, continuous bleeding around the time of menarche.
Haemoglobin and ferritin levels are used to determine the severity of bleeding and its impact on the haemoglobin level.
These analyses do not pinpoint the source of the problem, but they do pinpoint its consequences.
A haematologic reason, such as thrombocytopenia, acute leukaemia, or a coagulation/bleeding issue, affects about one-third of girls with pubertal menorrhagia (e.g. von Willebrand disease).
A complete blood examination and a bleeding
lotting profile are required to rule out these illnesses.
The results of a haemoglobin estimation or a ferritin level evaluation are insufficient, and the results of dilatation and curettage (D&C) or magnetic resonance imaging (MRI) will rarely reveal the reason for the bleeding.

During pelvimetry, the shape of the pubic arch is usually examined. It helps in determining the outcome of the type of fetal delivery.

During fertilization, a sperm must first fuse with the plasma membrane and then penetrate the female egg cell to fertilize it. Fusing to the egg cell usually causes little problem, whereas penetrating through the egg’s hard shell or extracellular matrix can be more difficult. Therefore, sperm cells go through a process known as the acrosome reaction, which is the reaction that occurs in the acrosome of the sperm as it approaches the egg. The acrosome is a cap-like structure over the anterior half of the sperm’s head. Upon penetration, if all is normally occurring, the process of egg-activation occurs, and the oocyte is said to have become activated. This is thought to be induced by a specific protein phospholipase c zeta. It undergoes its secondary meiotic division, and the two haploid nuclei (paternal and maternal) fuse to form a zygote. To prevent polyspermy and minimize the possibility of producing a triploid zygote, several changes to the egg’s cell membranes render them impenetrable shortly after the first sperm enters the egg.

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.

Despite the fact that this question includes many true-false options, the knowledge examined is particularly essential in the treatment of women who have genital herpes.
It answers many of the questions that such women have regarding the disease, how it spreads, how it may be controlled, and how it affects an unborn or recently born child.
All of these issues must be addressed in a counselling question.
Currently, the most prevalent type of genital herpes is type 1, while in the past, type 2 was more common, as confirmed by serology testing.
Type 2 illness is nearly always contracted through sexual contact, but it can go undetected for years.
Acyclovir can be taken during pregnancy, and there are particular reasons for its usage.
Neonatal herpes is most usually diagnosed when the newborn has no cutaneous lesions, and past genital herpes in the mother is protective against neonatal infection, although not always.
Where the genital infection is the initial sign of the disease rather than a relapse of earlier disease, neonatal herpes is far more frequent.
Many patients and doctors are unaware that, while the original infection might be deadly, it is usually asymptomatic.
This explains how the illness spreads between sexual partners when neither has had any previous symptoms of the disease.

The most common gram negative diplococci include Neisseria, haemophilus and Moraxella.

Uterine atony and failure of contraction and retraction of myometrial muscle fibres can lead to rapid and severe haemorrhage and hypovolemic shock. Poor myometrial contraction can result from fatigue due to prolonged labour or rapid forceful labour, especially if stimulated.

Umbilical cord prolapse (UCP) occurs when the umbilical cord exits the cervical opening before the fetal presenting part. It is a rare obstetric emergency that carries a high rate of potential fetal morbidity and mortality. Resultant compression of the cord by the descending foetus during delivery leads to fetal hypoxia and bradycardia, which can result in fetal death or permanent disability.

Certain features of pregnancy increase the risk for the development of umbilical cord prolapse by preventing appropriate engagement of the presenting part with the pelvis. These include fetal malpresentation, multiple gestations, polyhydramnios, preterm rupture of membranes, intrauterine growth restriction, preterm delivery, and fetal and cord abnormalities.

The occurrence of fetal bradycardia in the setting of ruptured membranes should prompt immediate evaluation for potential cord prolapse.

In overt prolapse, the cord is palpable as a pulsating structure in the vaginal vault. In occult prolapse, the cord is not visible or palpable ahead of the fetal presenting part. The definitive management of umbilical cord prolapse is expedient delivery; this is usually by caesarean section.

Induction of Labour is produced by the infusion of PGF-2 alpha or PGE2. Dinoprostone is a PGE2 and is associated with transient pyrexia that resolved within 4-5 hours of stopping the use of the drug.

The principal screening test for detecting maternal HBV infection is the serologic identification of HBsAg. Screening should be performed in each pregnancy, regardless of previous HBV vaccination or previous negative HBsAg test results.

A test for HBsAg should be ordered at the first prenatal visit. Women with unknown HBsAg status or with new or continuing risk factors for HBV infection (e.g., injection drug use or a sexually transmitted infection) should be screened at the time of admission to a hospital or other delivery setting.

Interventions to prevent perinatal transmission of HBV infection include screening all pregnant women for HBV, vaccinating infants born to HBV-negative mothers within 24 hours of birth, and completing the HBV vaccination series in infants by age 18 months.

Uterine bleeding in the presence of a closed cervix along with sonographic visualization of an intrauterine pregnancy with detectable fetal cardiac activity are diagnostic of threatened abortion.

Abortion does not always follow a uterine bleeding in early pregnancy, sometimes not even after repeated episodes or large amounts of bleeding, that is why the term “threatened” is used in this case. In about 90 to 96% cases, the pregnancy continues after vaginal bleeding if occured in the presence of a closed os and a detectable fetal heart rate. Also as the gestational age advances its less likely the condition will end in miscarriage.

In cases of inevitable abortion, there will be dilatation of cervix along with progressive uterine bleeding and painful uterine contractions. The gestational tissue can be either felt or seen through the cervical os and the passage of this tissue occurs within a short time.

In case were the membranes have ruptured, partly expelling the products of conception with a significant amounts of placental tissue left in the uterus is called as incomplete abortion. During the late first and early second trimesters this will be the most common presentation of an abortion. Examination findings of this includes an open cervical os with gestational tissues observed in the cervix and a uterine size smaller than expected for gestational age and a partially contracted uterus. The amount of bleeding will vary but can be severe enough to cause hypovolemic shock, with painful contractions and an ultrasound revealing tissues in the uterus.

An in utero death of the embryo or fetus prior to 20 weeks of gestation is called as a missed abortion. In this case the women may notice that the symptoms associated with early pregnancy like nausea, breast tenderness, etc have disappeared and they don’t ‘feel pregnant’ anymore. Vaginal bleeding may occur but the cervix remains closed and the ultrasound done reveals an intrauterine gestational sac with or without an embryonic/fetal pole, but no embryonic/fetal cardiac activity will be noticed.

In case of complete abortion, miscarriage occurs before the 12th week and the entire contents of conception will be expelled out of uterus. If this case, the physical examination will show a small and well contracted uterus with an open or closed cervix. There is scant vaginal bleeding with only mild cramping and ultrasound will reveal an empty uterus without any extra-uterine pregnancy.

Perineal tears are common at the time of child birth. First degree perineal laceration means that the wound is so small that it doesn’t require any stitches and usually heals on its own. 2nd degree means that skin and smooth muscles are both torn. 3rd degree tear means that the tear is beyond the perineal muscles and the muscles surrounding the anal canal, while in 4th degree, the perineal tear goes through the anal sphincter up to the rectum.

The gestational sac can be visualized from as early as 4–5 weeks of gestation and the yolk sac at about 5 weeks (Figure 6.3). The embryo can be observed and measured at 5–6 weeks gestation.

The pelvic outlet is bounded in front by the lower margin of the symphysis pubis, on each side by the descending ramus of the pubic bone, the ischial tuberosity and the sacrotuberous ligament, and posteriorly by the last piece of the sacrum. The AP diameter of the pelvic outlet is 13.5 cm and the transverse diameter is 11 cm.

Most common risk factors for spontaneous abortion are considered to be:
– Age above 35 years.
– Smoking.
– High intake of caffeine.
– Uterine abnormalities like leiomyoma, adhesions.
– Viral infections.
– Thrombophilia.
– Chromosomal abnormalities.
Conditions like subclinical thyroid disorder, subclinical diabetes mellitus and retroverted uterus are not found to cause spontaneous abortions.
The term retroverted uterus is used to denote a uterus that is tilted backwards instead of forwards.

RNA viruses are almost always single stranded whilst DNA viruses are almost always double stranded. The exceptions are rotavirus and Parvovirus B19 respectively.

A type II deceleration is due to placental insufficiency which can result in fetal distress and asphyxia. The fetal heart rate is lowest at the start of the contraction and returns to normal after the contraction is complete.

The lower vagina drains to the inguinal nodes where as the upper vagina drains to the internal and external iliacs

Breast infections can be associated with superficial skin or an underlying lesion. Breast abscesses are more common in lactating women but do occur in nonlactating women as well.

The breast contains breast lobules, each of which drains to a lactiferous duct, which in turn empties to the surface of the nipple. There are lactiferous sinuses which are reservoirs for milk during lactation. The lactiferous ducts undergo epidermalization where keratin production may cause the duct to become obstructed, and in turn, can result in abscess formation. Abscesses associated with lactation usually begin with abrasion or tissue at the nipple, providing an entry point for bacteria. The infection often presents in the second postpartum week and is often precipitated in the presence of milk stasis. The most common organism known to cause a breast abscess is S. aureus, but in some cases, Streptococci, and Staphylococcus epidermidis may also be involved.

The patient will usually provide a history of breast pain, erythema, warmth, and possibly oedema. Patients may provide lactation history. It is important to ask about any history of prior breast infections and the previous treatment. Patients may also complain of fever, nausea, vomiting, purulent drainage from the nipple, or the site of erythema. It is also important to ask about the patient’s medical history, including diabetes. The majority of postpartum mastitis are seen within 6 weeks of while breast-feeding

The patient will have erythema, induration, warmth, and tenderness to palpation at the site in question on the exam. It may feel like there is a palpable mass or area of fluctuance. There may be purulent discharge at the nipple or site of fluctuance. The patient may also have reactive axillary adenopathy. The patient may have a fever or tachycardia on the exam, although these are less common.

Incision and drainage are the standard of care for breast abscesses. If the patient is seen in a primary care setting by a provider that is not comfortable in performing these procedures, the patient may be started on antibiotics and referred to a general surgeon for definitive treatment. Needle aspiration may be attempted for abscesses smaller than 3 cm or in lactational abscesses. A course of antibiotics may be given before or following drainage of breast abscesses.

Circulation in the foetus: 1. Deoxygenated fetal blood is conducted to the placenta via the two umbilical arteries. The umbilical arteries arise from the internal iliac arteries.
2. Gas exchange occurs in placenta.
3. Oxygenated blood from the placenta passes through the single umbilical vein and enters the inferior vena cava (IVC).
4. About 50% of the blood in the IVC passes through the liver and the rest bypasses the liver via the ductus venosus. The IVC also drains blood returning from the lower trunk and extremities.
5. On reaching the heart, blood is effectively divided into two streams by the edge of the interatrial septum (crista dividens) (1) a larger stream is shunted to the left atrium through the foramen ovale (lying between IVC and left atrium) (2) the other stream passes into right atrium where it is joined by blood from SVC which is blood returning from the myocardium and upper parts of body. This stream therefore has a lower partial pressure of oxygen.
6. Because of the large pulmonary vascular resistance and the presence of the ductus arteriosus most of the right ventricular output passes into the aorta at a point distal to the origin of the arteries to the head and upper extremities. The diameter of the ductus arteriosus is similar to the descending aorta. The patency of the ductus arteriosus is maintained by the low oxygen tension and the vasodilating effects of prostaglandin E2;
7. Blood flowing through the foramen ovale and into left atrium passes into the left ventricle where it is ejected into the ascending aorta. This relatively oxygen rich blood passes predominantly to the head and upper extremities.

Reduced fetal movements can be the first indication of possible fetal abnormalities. Movements are first perceived by the mother from about 18-20 weeks gestation, increase in size and frequency until 32 weeks gestation when they plateau at about 31 movements per hour. Investigations for reduced fetal heart rate include auscultation of the fetal heart rate using a handheld doppler device, and a cardiotocograph or ultrasound if the foetus is above 28 weeks gestation. About 70% of women who experience one episode of reduced fetal movement have uncomplicated pregnancies. They are advised to report to a maternal unit if another episode occurs.

Bicornuate uterus is associated with an increased chance of urinary tract anomalies. Urinary tract anomalies were present in about 23.6% of cases of bicornuate uterus patients.

DNA replication occurs during S phase but that isn’t one of the options. Remember Interphase comprises G1,S and G2 phases!

In severe cases of hyperemesis, complications include vitamin deficiency, dehydration, and malnutrition, if not treated appropriately. Wernicke encephalopathy, caused by vitamin-B1 deficiency, can lead to death and permanent disability if left untreated. Additionally, there have been case reports of injuries secondary to forceful and frequent vomiting, including oesophageal rupture and pneumothorax.

Electrolyte abnormalities such as hypokalaemia can also cause significant morbidity and mortality. Additionally, patients with hyperemesis may have higher rates of depression and anxiety during pregnancy.

Blood enters the right atrium of the fetal heart and most passes through the foramen ovale into the left atrium. From there it is pumped through the aorta. The foramen ovale is the major structure for bypassing the fetal pulmonary circulation. Some of the blood in the right atrium does enters the right ventricle and then into the pulmonary artery however most of this passes through the ductus arteriosus into the aorta thus bypassing the fetal pulmonary circulation.

Oxytocin stimulates the myoepithelial cells in the breast causing the milk production. It also helps augment contractions in labour and cause uterine involution after childbirth.

Congenital Herpes Simplex Virus infection may cause high levels of morbidity and mortality in neonates. Risk of infection with HSV 1 and 2 is highest within 6 weeks of delivery and is transferred to the neonate via maternal secretions at birth. Affected babies can present as skin manifestations, CNS infection, or disseminated infection, which carries an 85% risk of mortality if left untreated. Treatment with high dose antivirals such as acyclovir can help decrease the case mortality rate to 30% in cases of disseminated infection.

CA-125 has found application as a tumour marker or biomarker that may be elevated in the blood of some patients with specific types of cancers, or other conditions that are benign. Increased level of CA125 appears in fifty percent of stage 1 ovarian cancer patients and more than 90% with stages 2-4 ovarian cancer. CA-125 is therefore a useful tool for detecting ovarian cancer after the onset of symptoms as well as monitoring response to treatment and for predicting a patient’s prognosis after treatment.

In this case, induction of labour at 37 weeks of gestation was necessary due to the absence of spontaneous of labour 24 hours after rupture of membranes. High doses of Syntocin and large volume of fluids may be required particularly when induction is done before term.

Syntocin infusion can lead to uterine hypertonus and tetany which can result in fetal distress at any dosage. This is a common reason to decrease or stop the infusion and an indication for Caesarean delivery due to fetal distress

Uterine rupture can occur as a result of Syntocin infusion especially when the accompanying fluids do not contain electrolytes, which puts the patient at risk for water intoxication.

Maternal hypotension results from Syntocin infusion, not hypertension.

The occurrence of migraine in women is influenced by hormonal changes throughout the lifecycle. A beneficial effect of pregnancy on migraine, mainly during the last 2 trimesters, has been observed in 55 to 90% of women who are pregnant, irrespective of the type of migraine.

For treatment of acute migraine attacks, 1000 mg of paracetamol (acetaminophen) preferably as a suppository is considered the first choice drug treatment. The risks associated with use of aspirin (acetylsalicylic acid) and ibuprofen are considered to be small when the agents are taken episodically and if they are avoided during the last trimester of pregnancy.

Paracetamol 500 mg alone or in combination with metoclopramide 10 mg are recommended as first choice symptomatic treatment of a moderate-to-severe primary headache during pregnancy.

In women of childbearing age, the most likely cause of abnormal vaginal bleeding is pregnancy; thus, the most appropriate initial test would be an hCG level. Once pregnancy has been excluded, patient history would guide further testing. Iatrogenic causes, usually resulting from certain medicines or supplements, are the next most common cause in this age group, followed by systemic disorders. Haemoglobin and haematocrit would be appropriate only if the patient seemed acutely anaemic due to the abnormal bleeding.

Leiomyomas uterine (fibroids)
Clinical features:
Menses that are heavy and last a long time, symptoms of pressure, pelvic discomfort, constipation, frequency of urination, complications during pregnancy, fertility problems, loss of pregnancy, premature birth, uterus enlargement and irregularity

Workup:
Ultrasound

Treatment:
Asymptomatic: monitoring
Surgical intervention, hormonal contraception

This patient has uterine leiomyomata, or fibroids, which are benign smooth muscle (myometrial) tumours that are very prevalent in adult women (up to 25%). These tumours can expand the endometrium’s surface area, the uterus’ overall size and thickness, and compress adjacent structures; nevertheless, some individuals have no symptoms and are identified by chance during a physical examination or imaging (as in this patient’s CT scan after a car accident).
Heavy, prolonged menses are among the indications for uterine leiomyomata treatment (particularly if associated with anaemia).
Pelvic discomfort that persists (e.g., dyspareunia).
Symptoms in abundance (e.g., pelvic pressure, hydronephrosis, constipation).
Recurrent miscarriages.
Medical or surgical treatment options are available for patients with these clinical characteristics (e.g., myomectomy).

This woman had mild menses and no pelvic discomfort or mass symptoms while having many big intramural and pedunculated leiomyomata (e.g., no ureter compression). There is no need for extra treatment in persons with asymptomatic fibroids. Only observation and reassurance are required.
In the treatment of symptomatic fibroids, a combination of oral contraceptive pills and progestin-containing intrauterine devices can be utilised, although they are not required in the management of asymptomatic fibroids. Furthermore, this patient has a minimal risk of unwanted pregnancy (e.g., monogamous, same-sex relationship), and the hazards of these contraceptives (e.g., venous thromboembolism, uterine perforation) outweigh the benefits.

GnRH agonist therapy (e.g., leuprolide) is a treatment for symptomatic uterine fibroids that works by inhibiting pulsatile FSH and LH production in the hypothalamus, lowering oestrogen levels. Low oestrogen levels cause a temporary reduction in leiomyoma size, which helps with heavy menses and bulky symptoms. Because long-term usage of GnRH agonists is linked to an increased risk of osteoporotic fractures, they are only administered preoperatively.

Tranexamic acid is a nonhormonal medicinal medication that reduces heavy menstrual bleeding by preventing fibrin breakdown (i.e., an antifibrinolytic drug). This patient’s menses are light.
Uterine leiomyomata (fibroids) are benign myometrial tumours that can produce a range of symptoms but are often identified by chance. Heavy menstrual blood, pelvic pain, and bulk symptoms are all indications for treatment. Patients with asymptomatic fibroids merely need to be monitored and reassured.

There is 70% chance that a women who has had a C-section can deliver via spontaneous vaginal delivery.

The metabolic adaptations of pregnancy are orchestrated by hormones produced by the placenta and maternal pituitary gland, which undergo dramatic changes during gestation. After involution of ovarian sex steroid production by wk 6, placental oestrogen and progesterone production increases exponentially to term. Concurrently, there are progressive increases in prolactin (PRL), produced by the maternal pituitary gland and decidua, and human chorionic somatomammotropin (CSH, also called human placental lactogen), which has structural similarities to GH and PRL.

OCPs should be started in this patient as well as condoms to prevent likely sexually transmitted infections.

Condoms alone are not effective for prevention of pregnancy.

OCPs alone do not prevent from sexually transmitted infections.

It is not appropriate to inform the parents and the patient hasn’t refused any advice.

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.

Nipple stimulation during breastfeeding triggers the production of oxytocin from the hypothalamus and its subsequent release from the posterior pituitary gland. The hormone causes the myoepithelial cells of the breast to contract causing milk to flow through the ducts.

Ergometrine and Prostaglandin E2 are used during labour to control uterine bleeding after delivery, or ripen the cervix, while Atosiban is an oxytocin antagonist.

Antidiuretic hormone is also released from the posterior pituitary, and acts on the kidneys to decrease fluid excretion.

Uterine blood flow increases 40-fold to approximately 700 mL/min at term, with 80 per cent of the blood distributed to the intervillous spaces of the placentae, and 20 per cent to the uterine myometrium. Weight of the uterus increases from 50–60 g prior to pregnancy to 1000 g by term.

The contents of the femoral triangles are femoral nerve, artery and the vein. Along with the femoral sheath and lymphatics.

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.

The Mantoux test is based on type IV hypersensitivity reaction.

The placenta does not have all the necessary enzymes to make oestrogens from cholesterol, or even progesterone. Human trophoblast lack 17-hydroxylase and therefore cannot convert C21-steroids to C19-steroids, the immediate precursors of oestrogen. To bypass this deficit, dehydroisoandrosterone sulphate (DHA) from the fetal adrenal is converted to estradiol-17ί by trophoblasts. In its key location as a way station between mother and foetus, placenta can use precursors from either mother or foetus to circumvent its own deficiencies in enzyme activities.

Transportation of the maternal IgG through the placenta starts around the 12 week of gestation.

Immediately after birth the liver is deprived of the large flow of blood supplied during foetal development via the umbilical vein and portal sinus. Simultaneously the blood pressure in the portal sinus, previously as high as in the umbilical vein, falls.

Oesophageal atresia of the foetus interrupts the normal circulation of the amniotic fluid. This causes polyhydramnios and subsequent distension of the uterus impacting proper expansion of the lungs. This would explain the difficulty breathing.

Taking into consideration that she had only missed one pill and that they were going to be stopped the next day anyway, the rate of pregnancy would be low; hence all of the responses would be acceptable and effective. However, the most appropriate step would be to initiate her hormone-free interval starting from the time she missed her pill i.e. 11pm the night before. This would make tonight the 2nd lactose pill day and hence she should commence the next course of hormone pills on the 5 nights from tonight. In doing this, her hormone-free period would be the usual length of 7 days. Although the risk of pregnancy is low after missing only one pill, this opposite occurs when the missed pill causes a longer than normal hormone-free duration between the end of the current cycle and the starting of the subsequent one.

Women with polycystic ovary syndrome (PCOS) have a 2.7-fold increased risk for developing endometrial cancer. A major factor for this increased malignancy risk is prolonged exposure of the endometrium to unopposed oestrogen that results from anovulation.

Additionally, secretory endometrium of some women with PCOS undergoing ovulation induction or receiving exogenous progestin exhibits progesterone resistance accompanied by dysregulation of gene expression controlling steroid action and cell proliferation.

Other risk factors include nulliparity, early menarche and late menopause, obesity and family history of endometrial cancer. Which rules out all the other options.

Clotting factor problem. Some of the more common disorders of coagulation that occur during pregnancy are von Willebrand disease, common factor deficiencies, platelet disorders and as a result of anticoagulants.

Antiphospholipid syndrome is the most important treatable cause of recurrent miscarriage. The mechanisms by which antiphospholipid antibodies cause pregnancy morbidity include inhibition of trophoblastic function and differentiation, activation of complement pathways at the maternal–fetal interface, resulting in a local inflammatory response and, in later pregnancy, thrombosis of the uteroplacental vasculature. This patient should be offered referral to a specialist clinic as she has had recurrent miscarriages. Low dose aspirin is one of the treatment options to prevent further miscarriage for patients with antiphospholipid syndrome.

Prolactin levels rise steadily during pregnancy during which time it promotes mammary growth (along with the other hormones mentioned below). Oestrogen and progesterone inhibit lactogenesis and it is only with the loss of these placental steroid hormones at term that Prolactin exhibits its lactogenic effect.

Anti phospholipid syndrome is an autoimmune disorder in which abnormal antibodies are formed which increases the risk of blood clots to develop in vessels and leads to recurrent miscarriages to occurs. The changes of recurrent miscarriage in a previously known case of APL is 15%.

The pudendal nerve has its origins form S2, S3 and S4 spinal segments. It provides sensation to the clitoris and labia along with the ilioinguinal nerve.

CDC urges all women of reproductive age to take 400 micrograms (mcg) of folic acid each day, in addition to consuming food with folate from a varied diet, to help prevent some major birth defects of the baby’s brain (anencephaly) and spine (spina bifida).

The use of lamotrigine during pregnancy has not been associated with an increased risk of neural tube defects; however, the recommendation regarding higher doses of folic acid supplementation is often, but not always, broadened to include women taking any anticonvulsant, including lamotrigine.

Listeria Monocytogenes is a cause of congenital infection. The most common source of the bacteria is food, especially unpasteurised milk. Congenital listeriosis can lead to spontaneous abortions, premature birth and chorioamnionitis. At birth, neonates may present with septicaemia, respiratory distress and inflammatory granulomatosis. The case mortality rate for listeriosis is thought to be between 20-30%.

Herpes simplex is a double stranded DNA virus. There are two viral types, HSV-1 and HSV-2. The majority of orolabial infections are caused by HSV-1. These infections are usually acquired during childhood through direct physical contact such as kissing. Genital herpes is a sexually transmitted infection and is most commonly caused by HSV-2.

Dermoid cysts and teratomas contain elements from multiple germ cell layers. They are often considered the same entity (even in medical texts) however a dermoid is composed only of dermal and epidermal elements. A teratoma has mesodermal and endodermal elements Mature teratomas are composed of well-differentiated derivations from at least 2/3 germ cell layers (i.e. ectoderm, mesoderm, and endoderm). They contain developmentally mature skin complete with hair follicles, sweat glands, sometimes hair, and sometimes sebum, blood, fat, bone, nails, teeth, eyes, cartilage, and thyroid tissue.
