The best next line of management is to administer an oxytocic (Syntocinon) infusion.

This is because the progress of labour is slow, and it necessary to augment it. As the membranes have already ruptured, the next step is to increase the contractions and induce labour using an infusion of oxytocic (Syntocinon) infusion.

Extra fluid is also required, but this will be administered alongside the Syntocinon infusion.

A lumbar epidural block is indicated in patients with an occipito-posterior (OP) position. This should not be attempted until more pain relief is required and the progress of labour is reassessed.

A Caesarean section may be necessary due to obstructed labour or fetal distress, it is not indicated at this stage.

Taking blood and holding it in case cross-matching is ultimately required is common, but most patients do not have blood cross-matched prophylactically in case there is a need to be delivered by Caesarean section and require a transfusion.

Labour induction is indicated as no fetal movements have been felt for 24 hours, with a normal cardiotocograph (CTG) and the pregnancy is at near/full term with a favourable cervix.

Amniotic fluid volume assessment would have been indicated 24 hours earlier as, if it was low, induction would have been indicated then, despite a normal CTG.

Ultrasound examination of the foetus is not indicated as it is necessary to expedite delivery.

Carrying out another CTG, with or without oxytocin challenge, is not indicated, although MG monitoring during induced labour would be mandatory.

Delivery immediately by Caesarean section is not indicated unless the lack of fetal movements is due to fetal hypoxia. This can result in fetal distress during labour, necessitating an emergency Caesarean section if the cervix is not fully dilated.

The best antibiotic of choice for empirical treatment of a urinary tract infection (UTI) during pregnancy is cephalexin. Nitrofurantoin and amoxicillin-clavulanate are second and third in-line respectively.
Patients allergic to penicillin, which is manifested as a rash can also be safely treated with cephalexin. But cephalosporins are not recommended if the presentation of allergic reaction to penicillin was anaphylactic, instead they should be treated with nitrofurantoin.

NOTE– Asymptomatic bacteriuria, such as >10 to power of 5 colony count in urine culture of an asymptomatic woman in pregnancy, should best be treated with a one week course of antibiotics, followed by confirming the resolution of infection via a urine culture repeated 48 hours after the completion of treatment.

Amoxicillin without clavulanate is recommended only in cases were the susceptibility of the organism is proven.

Macrolides like clarithromycin are usually not recommended for the treatment of UTI.

Aminoglycosides are coming under category D drugs should be avoided during pregnancy, unless there is a severe indication of gram negative sepsis.

Tetracycline, due to their potential teratogenic effects, are contraindicated in pregnancy.

The BPP is performed in an effort to identify babies that may be at risk of poor pregnancy outcome, so that additional assessments of wellbeing may be performed, or labour may be induced or a caesarean section performed to expedite birth.

Among all the antiepileptic drugs sodium valproate carries the highest teratogenicity rate. The potential congenital defects caused by sodium valproate are as below:
– Neural tube defects like spina bifida, anencephaly
– Cardiac complications like congenital ventricular septal defect, aortic stenosis, patent ductus arteriosus, aberrant pulmonary artery
– Limb defects like polydactyly were more than 5 fingers are present, oligodactyly were less than 5 fingers are present, absent fingers, overlapping toes, camptodactyly which is presented as a fixed flexion deformity of one or more proximal interphalangeal joints,split hand, ulnar or tibial hypoplasia.
– Genitourinary defects like hypospadias, renal hypoplasia, hydronephrosis, duplication of calyceal system.
– Brain anomalies like hydranencephaly, porencephaly, arachnoid cysts, cerebral atrophy, partial agenesis of corpus callosum, agenesis of septum pellucidum, lissencephaly of  medial sides of occipital lobes, Dandy-Walker anomaly
– Eye anomalies like bilateral congenital cataract, optic nerve hypoplasia, tear duct anomalies, microphthalmia, bilateral iris defects, corneal opacities.
– Respiratory tract defects like tracheomalacia, lung hypoplasia,severe laryngeal hypoplasia, abnormal lobulation of the right lung, right oligemic lung which is presented with less blood flow.
– Abdominal wall defects like omphalocele
– Skin abnormalities capillary hemangioma, aplasia cutis congenital of the scalp.

In most cases reported, puerperal hematomas arise due to bleeding lacerations related to operative deliveries or episiotomy, and in rare cases from spontaneous injury to a blood vessel in the absence of any laceration/incision of the surrounding tissue. Vulval, vaginal/paravaginal area and retroperitoneum are considered the most common locations for puerperal hematomas.

Most puerperal hematomas are diagnosed based on the presence of characteristic symptoms and physical examination findings:
VuIvar hematoma usually presents as a rapidly developing, severely painful, tense and compressible mass which is covered by skin of purplish discoloration. A vulvar hematoma can also be an extension of a vaginal hematoma which was dissected through a loose subcutaneous tissue into the vulva.
Vaginal hematomas often present with rectal pressure, were hemodynamic instability caused due to bleeding into the ischiorectal fossa and paravaginal space are the first signs and can result in hypovolemic shock. In these cases a large mass protruding into the vagina is often found on physical examination.
Retroperitoneal hematomas are asymptomatic initially and extend between the folds of broad ligament. Patients suffering will often present with tachycardia, hypotension or shock due to the significant accumulated of blood in the retroperitoneal space. Unless the hematoma is associated with trauma, patients will not present with pain, only signs will be a palpable abdominal mass or fever.

Treatment of hematoma depends mostly on the size and location:
Non-expanding hematomas which are <3cm in size can be managed conservatively with analgesics and application of ice packs. An expanding hematoma or those greater than 3cm is managed effectively with surgical exploration under anesthesia, were an incision is made to evacuate the hematoma. The surgical site should not be sutured and vagina is often packed for 12-24 hours, an indwelling urinary catheter also may be indicated. In the given case, patient presents with a large haematoma (>3cm) which needs surgical excision and evacuation.

Aspiration of the hematoma is not an appropriate treatment. If surgical intervention is indicated excision and evacuation is the preferred option, followed by vaginal packing for 12-24 hours.

Mitosis is the process during which cell division occurs. It is divided into 4 stages:
– The first stage is the prophase during which the chromosomes condense, mitotic spindles form and the chromosomes pair which each other.
– The second stage is the metaphase during which the chromatids align at the equatorial plane.
– The third stage is the anaphase during which the chromatids are separated into 2 daughter chromosomes.
– The fourth phase is the telophase during which the chromatids decondense and a new nuclear envelop forms around the each of the daughter chromosomes. Cytokinesis is the process during which the cell cytoplasm divides.

The ischial spines and palpable through the vagina and are used as landmarks to assess the decent of the fetal head from the cervix. It also serves as a landmark for giving the pudendal block.

Paget’s disease of the breast is a type of cancer that outwardly may have the appearance of eczema, with skin changes involving the nipple of the breast. Symptoms may include redness of the nipple skin and crusting may occur around the area. In more advance cases, symptoms may include itching or a burning pain in the nipple.

As this is a simple cyst less than 50mm in diameter the patient does not require further investigation or routine follow up

Its important to note the endo and ectocervix have 2 epithelial types. Where columnar and squamous epithelia meet is the transformation zone (or squamous-columnar junction, SCJ). This is relevant as it is the primary site for dysplasia and is where smears are taken from.

The postpartum period begins soon after the baby’s delivery and usually lasts six to eight weeks and ends when the mother’s body has nearly returned to its pre-pregnant state.

Bloody vaginal discharge (lochia rubra) is heavy for the first 3-4 days, and slowly it becomes watery in consistency and colour changes to pinkish-brown (lochia serosa). After the next 10-12 days, it changes to yellowish-white (lochia alba). Advise women to seek medical attention if heavy vaginal bleeding persists (soaking a pad or more in less than an hour). Women with heavy, persistent postpartum bleeding should be evaluated for complications such as retained placenta, uterine atony, rarely invasive placenta, or coagulation disorders. Endometritis may also occur, presenting as fever with no source, maybe accompanied by uterine tenderness and vaginal discharge. This usually requires intravenous antibiotics. This also should be explained and advise the mother to seek immediate medical attention.

Uterine blood flow increases 40-fold to approximately 700 mL/min at term. The uterus is 50–60 g with a volume of approximately 10ml prior to pregnancy and 1000 – 1200 g with a volume of 5000ml by term.

Fetal heart rate tracings (FHR) under category I include all of the following:
– baseline rate 110– 160 bpm
– baseline FHR variability moderate
– accelerations present or absent
– late or variable decelerations absent
– early decelerations present or absent

The onset of fetal bleeding is marked by a tachycardia followed by a bradycardia with intermittent accelerations or decelerations. Small amounts of vaginal bleeding associated with FHR abnormalities should raise the suspicion of fetal haemorrhage. This condition demands prompt delivery and immediate reexpansion of the neonatal blood volume.

The fetal head is engaged when the head of the foetus or the presenting part enters the pelvic inlet or pelvic brim. It usually occurs at 38 weeks of gestation.
The Spalding sign refers to the overlapping of the fetal skull bones caused by collapse of the fetal brain. It appears usually a week or more after fetal death in utero.
In brow presentation the scalp is deflexed as the foetus is looking upward. Normally the head is inflexed such that the chin is touching the chest.

Ectopic pregnancy is a known complication of pregnancy that can carry a high rate of morbidity and mortality when not recognized and treated promptly. It is essential that providers maintain a high index of suspicion for an ectopic in their pregnant patients as they may present with pain, vaginal bleeding, or more vague complaints such as nausea and vomiting. Ectopic pregnancy, in essence, is the implantation of an embryo outside of the uterine cavity most commonly in the fallopian tube.

Providers should identify any known risk factors for ectopic pregnancy in their patient’s history, such as if a patient has had a prior confirmed ectopic pregnancy, known fallopian tube damage (history of pelvic inflammatory disease, tubal surgery, known obstruction), or achieved pregnancy through infertility treatment.

Performance of laparoscopic surgery is safe and effective treatment modalities in hemodynamically stable women with a non-ruptured ectopic pregnancy.

Patients with relatively low hCG levels would benefit from the single-dose methotrexate protocol. Patients with higher hCG levels may necessitate two-dose regimens. There is literature suggestive that methotrexate treatment does not have adverse effects on ovarian reserve or fertility. hCG levels should be trended until a non-pregnancy level exists post-methotrexate administration.

Surgical management is necessary when the patients demonstrate any of the following: an indication of intraperitoneal bleeding, symptoms suggestive of ongoing ruptured ectopic mass, or hemodynamically instability. Women who present early in pregnancy and have testing suggestive of an ectopic pregnancy would jeopardize the viability of an intrauterine pregnancy if given Methotrexate. The patient may have a cervical ectopic pregnancy and would thus run the risk of haemorrhage and potential hemodynamic instability if a dilation and curettage are performed.

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

The median umbilical ligament is the remnant of the Urachus.

The next best line of management is immediate delivery via Caesarean section ( C section).

This is because of the change in cardiotocography (CTG). The pattern became much more severe with a virtual lack of short-term variability and prolonged decelerations. These changes indicate the necessity for an immediate C section as the cervix is not fully dilated.

As immediate delivery is indicated, another pH assessment is unnecessary as it would delay delivery and increase the likelihood of fetal hypoxia.

Delivery by ventose, in a primigravida where the cervix is only 8cm dilated is not indicated as it would allow the labour to proceed or augmenting with Syntocinon.

Lichen sclerosis (LS) is a benign, chronic, progressive dermatologic condition characterized by marked inflammation, epithelial thinning, and distinctive dermal changes accompanied by symptoms of pruritus and pain.

Topical corticosteroids are the mainstay of therapy. Intralesional corticosteroid therapy is an additional option that is useful for the treatment of thick hypertrophic plaques that topical corticosteroids may not penetrate adequately.

Antibiotics or antifungals have no role in the treatment of LS since it’s not an infection.
Since histological diagnosis has already been made, there is no need to refer to dermatologist.
Surgical intervention is indicated for treatment of complications like adhesion and scarring.

In post menopausal women the thickness of the endometrium should be 4mm or less or women on tamoxifen is should be less than 5mm. If it is more than this the patient should be worked up for endometrial carcinoma.

Intrahepatic cholestasis of pregnancy can affect both mother and foetus, however it is more harmful for the foetus. Amongst foetuses, there is an increased risk of perinatal mortality, meconium aspiration, premature delivery and post partum haemorrhage. Exact cause of fetal death cannot be predicted accurately but it is not related to intra uterine growth retardation or placental insufficiency. The liver can be affected in the mother leading to generalized pruritis but no evidence of fetal hepatic dysfunction has been found.

It is stage 2B. Stage I: is strictly confined to the cervix; extension to the uterine corpus should be disregarded. The diagnosis of both Stages IA1 and IA2 should be based on microscopic examination of removed tissue, preferably a cone, which must include the entire lesion.
2010 FIGO classification of cervical carcinoma:
Stage IA: Invasive cancer identified only microscopically. Invasion is limited to measured stromal invasion with a maximum depth of 5 mm and no wider than 7 mm.
Stage IA1: Measured invasion of the stroma no greater than 3 mm in depth and no wider than 7 mm diameter.
Stage IA2: Measured invasion of stroma greater than 3 mm but no greater than 5 mm in depth and no wider than 7 mm in diameter.

Stage IB: Clinical lesions confined to the cervix or preclinical lesions greater than Stage IA. All gross lesions even with superficial invasion are Stage IB cancers.
Stage IB1: Clinical lesions no greater than 4 cm in size.
Stage IB2: Clinical lesions greater than 4 cm in size.

Stage II: carcinoma that extends beyond the cervix, but does not extend into the pelvic wall. The carcinoma involves the vagina, but not as far as the lower third.
Stage IIA: No obvious parametrial involvement. Involvement of up to the upper two-thirds of the vagina.
Stage IIB: Obvious parametrial involvement, but not into the pelvic sidewall.

Stage III: carcinoma that has extended into the pelvic sidewall. On rectal examination, there is no cancer-free space between the tumour and the pelvic sidewall. The tumour involves the lower third of the vagina. All cases with hydronephrosis or a non-functioning kidney are Stage III cancers.
Stage IIIA: No extension into the pelvic sidewall but involvement of the lower third of the vagina.
Stage IIIB: Extension into the pelvic sidewall or hydronephrosis or non-functioning kidney.

Stage IV: carcinoma that has extended beyond the true pelvis or has clinically involved the mucosa of the bladder and/or rectum.
Stage IVA: Spread of the tumour into adjacent pelvic organs.
Stage IVB: Spread to distant organs.

The femoral triangle is bounded superiorly by the inguinal ligament which forms the base of the triangle, medially by the lateral border of the adductor longus and laterally by the sartorius muscle.

The T10 spinal segment provides the sympathetic nerve fibres that innervate the testes

When testing for ovulation the best test is to check the progesterone level. The mid luteal progesterone levels should be checked 7 days prior to the next period. That will be the 28th day in a 35 day cycle.

A brow presentation in a nulliparous woman is associated with high risk of obstructed labour and the need for delivery by Caesarean section.

Brow presentation occurs when the presenting part of the fetal head is the part between the orbital ridge and anterior fontanelle.

In multiparous women, the indications differ as vaginal manipulation or spontaneous flexion to a vertex presentation or extension to a face presentation can occur after full cervical dilatation.

Early fetal heart decelerations are indicative of a mild abnormality on cardiotocograph (CTG). It does not indicate obstructive labour or need for delivery by Caesarean section.

The slow descent of the fetal head can be controlled subsequently by good uterine contractions and allow for vaginal birth.

Prolonged labour can cause maternal fever, but that in isolation is not an indication for Caesarean section.

Caput and head moulding are associated with a ‘tight fit’ of the fetal head in the pelvis, but does not contraindicate vaginal birth.

During early pregnancy, hCG can be detected in the maternal serum as early as 6 to 8 days after fertilization. hCG levels are dynamically increased and doubled every 48 h in most normal pregnancies, and this pattern is similar in both in vivo or in vitro (IVF) conceptions.

The presentation is antepartum haemorrhage. Ultrasound should be performed to find the reason for bleeding and assess the fetal well being.

The treatment of asphyxia starts with the correct perinatal management of high-risk pregnancies. The management of the hypoxic-ischemic new-borns in the delivery room is the second fundamental step of the treatment. Low Apgar scores and need for cardiopulmonary resuscitation at birth are common but nonspecific findings. Most new-borns respond rapidly to resuscitation and make a full recovery. The outcomes for new-borns who do not respond to resuscitation by 10 minutes of age are very poor, with a very low probability of surviving without severe disability. Resuscitation in room air is advised for term new-borns, since the use of 100% oxygen is associated with worse outcomes compared to the use of room air.

Gestational trophoblastic disorder is characterized by an abnormal trophoblastic proliferation and include a complete and partial mole. It is characterized by persistently elevated BHCG levels after pregnancy and on ultrasound a snow storm appearance. These appear as anechoic areas on ultrasound.

Spinnability (or Spinnbarkeit), which measures the capacity of fluids to be drawn into threads, represents an indirect measurement of the adhesive and elastic properties of mucus.

The average volume of uterine blood flow at term is 500-750 ml/min.

Domperidone and metoclopramide are D2 dopamine receptor antagonists. They are primarily used to promote gastric motility. They are also known as galactagogues and they promote the production of milk. Cabergoline and bromocriptine are prolactin inhibitors and they reduce milk production.

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

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

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

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

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

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

Multiparous women active 2nd stage labour: Suspect delay if progress inadequate after 30 minutes Diagnose delay if progress inadequate after 1 hour If delay is suspected amniotomy should be offered if membranes are intact If delay diagnosed then preparations should be made for C-section Nulliparous women active 2nd stage labour: Suspect delay if progress inadequate after 1 hour Diagnose delay if progress inadequate after 2 hours If delay is suspected amniotomy should be offered if membranes are intact If delay diagnosed then preparations should be made for C-section

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.

The correct answer is Obstetric Cholestasis.
The characteristics (elevated bile acids, conjugated bilirubin, and alkaline phosphatase (ALP) levels) are typical with obstetric cholestasis, which affects roughly 3-4 percent of pregnant women in Australia. Obstetric cholestasis is diagnosed when otherwise unexplained pruritus occurs in pregnancy and abnormal liver function tests (LFTs) and/or raised bile acids occur in the pregnant woman and both resolve after delivery. Pruritus that involves the palms and soles of the feet is particularly suggestive.
Liver function tests and bile acid levels measurements are used to validate this diagnosis.
All of the other diagnoses are theoretically possible, but unlikely.
On liver function tests, hepatitis A and acute fatty liver of pregnancy (which is frequently associated with severe vomiting in late pregnancy) usually show substantially worse hepatocellular damage.
Pre-eclampsia is connected with hypertension and proteinuria (along with changes in renal function and, in certain cases, thrombocytopenia), while cholelithiasis is associated with obstructive jaundice and pale stools due to a stone in the CBD.

Patient mentioned in the case has developed severe nausea and vomiting at the initial weeks of pregnancy. If the following clinical features are present, it confirms the diagnosis of hyperemesis gravidarum:
– Weight loss of more than 5% of pre-pregnancy weight
– Moderate to severe dehydration.
– Ketosis
– Electrolyte abnormalities.

Management of hyperemesis gravidarum include:
– Temporary suspension of oral intake, followed by gradual resumption.
– Intravenous fluid resuscitation, beginning with 2 L of Ringer’s lactate infused over 3 hours to maintain a urine output of more than 100 mL/h.
– Use of Antiemetics like metoclopramide, if needed.
– Oral administration of Vitamin B6.
– Replacement of electrolytes if required in the case.

Encouraging oral intake and sending this patient home without any intravenous hydration, is not considered the correct treatment option in this case.

The placenta is important for regulating feto-maternal blood circulation, ensuring that the two circulatory systems do not come into direct contact. The placenta receives 70-80% of the uterine blood flow into the decidual spiral arteries where nutrient, waste and gaseous exchange with fetal blood takes place via the villous core fetal vessels. Deoxygenated blood arrives at the placenta via two uterine arteries while oxygenated, nutrient-rich blood is circulated back to the foetus via a single umbilical vein. The pressure in the umbilical vein is about 20 mmHg.

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.

Breakthrough bleeding, or spotting, refers to when vaginal bleeding occurs between menstrual cycles. It may look like light bleeding or brown discharge.

Spotting is the most common side effect of birth control pills. It happens because the body is adjusting to changing levels of hormones, and the uterus is adjusting to having a thinner lining.

Taking the pill as prescribed, usually every day and at the same time each day, can help prevent bleeding between periods.

All other options are incorrect as this is a common side effect and will resolve on its own.

The Apgar test scores appearance, pulse, grimace, activity, and respiration and is generally done at 1 and 5 minutes after birth but may be repeated if the child continues to score low (Table). This child’s score is as follows: Appearance, 1; Pulse, 1; Grimace, 2; Activity, 2; Respiration, 2 (APGAR score = 8). A score of 3 or less is generally regarded as critically low, 4 to 6 is fairly low, and 7 to 10 is generally normal. Contrary to common belief, the Apgar score is not used to decide if a neonate requires resuscitation. Decisions about resuscitation are based on emergency assessment of airway, breathing, and circulation.5,6

Uncontrolled endometrial proliferation due to excess and unregulated estrogen is the reason for intermenstrual bleeding and irregular menses along with abnormal uterine bleeding (AUB) in this patient. The condition is mostly associated with an increased risk of endometrial hyperplasia
ancer.
The absolute risk of endometrial hyperplasia
ancer is very low in women aged <45, therefore they can be started on combination medication with estrogen/progestin contraception (ie, medical management) without the evaluation of endometrium.  The estrogen component of medication regulates the menstrual cycle by build up the endometrium; whereas the progestin component helps in shedding of the endometrium.
However, patients who have continued irregular menstrual bleeding even while on combination contraceptives require further evaluation as they have failed to improve with medical management. In such patients, the endometrial lining will be too thick for the progestin to completely shed during menstruation and this unshed endometrium continues to undergo dysregulated proliferation, leading to an increased risk of endometrial hyperplasia
ancer. Therefore, patients age below 45 with AUB who have failed medical management require an endometrial biopsy.
AUB persistent above 6 months, obesity, and/or tamoxifen therapy are the other indications for endometrial biopsy in women age <45, as all of these will increase the amount of unopposed endometrial estrogen exposure. In patients with heavy menstrual bleeding and anemia, coagulation studies are performed to evaluate for bleeding disorders like von Willebrand disease. It is not necessary in this patient as she have a normal hemoglobin level. In patients with heavy, but regular (ovulatory) bleeding an endometrial ablation, which is a procedure used to remove the excess endometrium, can be considered as the treatment option. Endometrial ablation is contraindicated in undiagnosed cases of AUB as it prevents evaluation of the endometrium in patients with possible endometrial hyperplasia
ancer.

To check for abnormalities of the uterus like didelphys or of the Fallopian tube like scarring, a hysterosalpingogram is used but it is not useful to evaluate AUB. In addition, as the procedure could spread cancerous endometrial cells into the abdominal cavity, hysterosalpingogram is contraindicated in cases of undiagnosed AUB.

To evaluate secondary amenorrhea, ie. absence of menses for >6 months in a patient with previously irregular menses, a progesterone withdrawal test is used to determine whether amenorrhea is from low estrogen level, in negative cases there will be no bleeding after progesterone. This test is not indicated or relevant in this case as patient had continued bleeding while on oral contraceptives suggestive of high estrogen levels.

Evaluation for endometrial hyperplasia
ancer with an endometrial biopsy is required for those women age <45 with abnormal uterine bleeding who have failed medical management with oral contraceptives.

Factor V Leiden is the most common congenital thrombophilia. Named after the Dutch city Leiden where it was first discovered. Protein C and S deficiencies are type 1 (Not type 2) thrombophilias Antiphospholipid syndrome is an acquired (NOT congenital) thrombophilia

Thyroid function in pregnancy is altered in two ways; the circulating levels of the thyroid binding proteins are increased, resulting in an increase in the total circulating levels of thyroid hormones (but a slight fall in the free component).

History of amenorrhoea, abdominal and vaginal examination are more favour of ectopic pregnancy. Endometriosis usually has a chronic cause and dysmenorrhoea. Salpingitis usually presents with fever. Ovarian torsion and ovarian tumours have different clinical presentations.

Congenital Adrenal Hyperplasia leads to the virilization of the foetus. It occurs due to an enzyme deficiency in the corticosteroid production pathway i.e. 21-hydroxylase which converts progesterone to deoxycorticosterone. The reduced levels of corticosteroids results in the negative feedback loop that leads to adrenal hyperplasia.

The superficial ring is the exit to the inguinal canal. It is a triangular aperture in the aponeurosis of external oblique. The conjoint tendon reinforces the ring posteriorly
