Ulipristal is a progesterone receptor modulator that is used up to 120 hours following unprotected intercourse. It inhibits ovulation. The dose is 30 mg.

This patient has developed deep vein thrombosis during pregnancy and required anti-coagulation as part of treatment for up to 3-6 months. Enoxaparin, which is a low molecular weight heparin, is preferred over heparin due to the once or twice a day therapeutic dosing. Also monitoring of aPTT is not required in this case.

There is an association between Enoxaparin and an increased risk for epidural hematoma in women receiving epidural anaesthesia during labour. Considering that the patient mentioned is expected to go for delivery in 4 weeks and the possibility of her needing an epidural anaesthesia or general anaesthesia in case of undergoing a cesarean section, enoxaparin should be switched to unfractionated heparin, four weeks prior to the anticipated delivery. This is because of the fact that heparin can be antidoted with protamine sulphate.

Human chorionic gonadotropin levels dynamically increase during early gestation and the levels are significantly greater in viable pregnancies than in ectopic gestation, biochemical pregnancy, or spontaneous abortions. Similarly, the hCG concentrations are significantly higher in multiple pregnancy as compared with singleton.

Progestin only pills increase the risk of developing follicular cysts. Sonographic studies have observed that follicular cysts are more common in POP users than women not using hormones. The follicular changes tend to increase and regress over time. No intervention is required in asymptomatic women, other than reassurance. POP users who have persistent concerns about ovarian follicular changes should be offered another method of contraception.

All other options are not contraindications to the use of mini-pills.

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.

Early ultrasound improves the early detection of multiple pregnancies and improved gestational dating may result in fewer inductions for post maturity.

Factors shown to decrease risk of ovarian cancer are:
– Oral contraceptive use
– Higher Parity
– Breast feeding
– Hysterectomy
– Tubal Ligation
– Statins
– SLE

Arcuate means ‘bow shaped’ and there are different arcuate lines in anatomical terms. Regarding the pelvic brim this is composed of the arcuate line of the ilium, pectineal line and prominences of sacrum and pubic symphysis (as demonstrated in the images below). As can be seen the arcuate line is a smooth rounded border on the internal surface of the ilium inferior to the iliac fossa and Iliacus. Image sourced from Wikipedia Note: The pelvic outlet is also called the inferior aperture. The pelvic brim is the superior aperture

A local exam might not help in locating the cause of the bleeding because it might be underneath the superficial structures. A thorough examination should be done under GA to accurately locate the source of bleeding.

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 external carotid develops from the 1st arch. The common and internal carotid develop from the 3rd arch.

Free T3 (FT3) and free T4 (FT4) levels are slightly lower in the second and third trimesters. Thyroid-stimulating hormone (TSH) levels are low-normal in the first trimester, with normalization by the second trimester.

This woman has developed non-specific symptoms of cervical insufficiency, is a painless dilation of cervix resulting in the delivery of a live fetus during the 2nd trimester or premature delivery.

The following has been identified as the risk factors associated with increased incidence of cervical insufficiency:
– Congenital disorders of collagen synthesis like Ehlers-Danlos syndrome.
– Prior cone biopsies.
– Prior deep cervical lacerations, which is secondary to vaginal or cesarean delivery.
-Müllerian duct defects like bicornuate or septate uterus.
– More than three prior fetal losses during the 2nd trimester

From the given options, alcohol abuse is the only one not associated with increased incidence of cervical insufficiency.

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.

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

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

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

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

The pudendal nerve arises from the S2-S4 nerve roots and it lies medial to the internal pudendal artery while exiting the pelvis via the greater sciatic foramen. It curves around the sacrospinous ligament and re-enters the pelvis via the lesser sciatic foramen and from there it runs medial to the ischial tuberosity over the obturator internus in the pudendal canal to the deep perineal pouch.

Obligate anaerobes are a group of bacteria that cannot survive in an oxygen-rich environment. In the body, they are usually found on mucosal membranes such as that of the lower gastrointestinal system, or the vagina. Infection with these organisms is usually suprative and causes abscesses. Examples of gram-negative anaerobes include Bacteroides, Fusobacterium and Prevotella, while gram-positive anaerobes include Actinomyces and Clostridia. Staphylococcus and Streptococcus are both gram-positive facultative anaerobes.

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.

The woman’s blood pressure was elevated at her visit; therefore she should be advised to immediately cease the oral contraceptive pill (OCP) so that the hypertension can resolve without the need for any hypotensive treatment. The blood pressure can then be reassessed in three months. Alternative, non-hormonal birth control methods such as condoms should be used instead.

If her high blood pressure does not resolve, any medication that would be commenced to reduce her blood pressure should be one that is safe to continue when she becomes pregnant.

It is inappropriate to continue the OCP even at a lower dosage or in combination with a hypotensive agent.

Methyldopa has been evaluated and used for treatment of hypertension during pregnancy. There is no clinical evidence to suggest that it causes harm to the foetus or neonate.

Angiotensin converting enzyme (ACE) inhibitors are not approved for use in pregnancy as they have been associated with fetal death in utero. Other antihypertensive agents such as beta-blockers and diuretics are also problematic in pregnancy and should be avoided.

In pregnancy, progesterone is produced by the corpus luteum followed by the placenta- Exogenous progesterone will not lead to withdrawal bleeding. In ovarian failure as well as pituitary failure, no oestrogen stimulation of the endometrium exists, and progesterone cannot cause withdrawal bleeding. With Mullerian agenesis, there is no endometrium. Polycystic ovarian syndrome has an abundance of circulating oestrogen, so the endometrium will proliferate.

→ In pregnancy progesterone withdrawal will not occur since the corpus luteum is producing progesterone- The placenta will take over, starting at 7 weeks, and will be the sole producer of progesterone by 12 weeks.
→ In ovarian failure no oestrogen will be produced; no proliferation of the endometrium will occur.
→ Pituitary failure is an incorrect answer because without gonadotropin stimulation, there will not be enough oestrogen to stimulate the endometrial lining.
→ Mullerian agenesis is an incorrect answer – there is no uterus, thus no bleeding.

B-HCG levels almost double every 48 hours. A B-HCG levels of less than 5 mIU/ml is considered negative and anything above 25 is considered positive. As the foetus was not visualized on ultrasound in the uterus, there is possibility that this might be an ectopic pregnancy. But since the B-HCG levels also continued to fall the pregnancy becomes non-viable.

Normal position of the foetus in relationship to the mother is always a longitudinal lie and a cephalic presentation. Transverse lie means that the baby is sideways. The foetus lies transverse till 26-28th week of gestation, after which it usually changes its position from transverse to a longitudinal lie with head down. A transverse lie can occur in conditions like grand multiparity, preterm foetus, placenta previa and pelvic contraction.

During the 5th week, the neural crest cells migrate along each side of the spinal cord where they form ganglions located dorsolateral to the aorta. Some of these cells migrate ventrally and form neurons in the preaortic ganglia as the celiac and mesenteric ganglia.

Lymphatic drainage of the bladder is to the common iliac nodes via the internal iliac nodes.

As the most likely diagnosis, this woman meets diagnostic criteria for premenstrual syndrome (PMS).
Affective and physical symptoms that begin one week before menstruation and end four days after menstrual flow begins are diagnostic criteria for premenstrual syndrome. The symptoms must be present for at least three menstrual cycles and must not occur during the preovulatory period.
It’s critical to note that these symptoms are not caused by any medical or psychological condition, medications, drugs, or alcohol.

Premenstrual dysphoric disorder is a severe form of premenstrual syndrome marked by intense melancholy, emotional lability with frequent tears, and a lack of interest in daily activities. To put it another way, emotional impairment is the most prominent trait.

This woman does not meet the diagnostic criteria for PMDD because she only has psychological symptoms of irritation and anxiety, as well as physical symptoms of headache and breast soreness (five symptoms).

PMDD diagnostic criteria include:
Symptoms and their timing
A) At least 5 symptoms must be present in the final week before menses, improve within a few days after menses, and become mild or non-existent in the week after menses in the majority of menstrual cycles.
Symptoms
B) At least one of the symptoms listed below must be present:
1) Affective lability that is noticeable (e.g., mood swings, feeling suddenly sad or tearful, or increased sensitivity to rejection)
2) Excessive irritation, wrath, or interpersonal conflicts
3) Depressed mood, hopelessness, and self-depreciating thoughts
4) Severe anxiety, tension, and/or a sense of being tense or on edge
C) In addition to the symptoms listed in criterion B, one (or more) of the following symptoms must also be present to reach a total of five symptoms.
1) Loss of enthusiasm for customary activities
2) Subjective concentration problems
3) Lethargy, fatigability, or a noticeable lack of energy
4) Significant changes in appetite, such as binge eating or specific food desires
5) Insomnia or hypersomnia
6) A feeling of being overwhelmed or powerless
7) Physical signs and symptoms include breast discomfort or swelling, joint or muscle pain, bloating, or weight gain.
Severity
D)The symptoms are linked to clinically substantial distress or interfere with employment, school, regular social activities, or interpersonal relationships.
E) Think about other mental illnesses. The disturbance isn’t only a sign of another disorder, like major depressive disorder, panic disorder, persistent depressive disorder (dysthymia), or a personality disorder (although it may co-occur with any of these disorders).
Confirmation of the condition
F)Prospective daily ratings throughout at least two symptomatic cycles should be used to confirm Criterion A. (although a provisional diagnosis may be made prior to this confirmation)
Other medical explanations are ruled out.
G) The symptoms aren’t caused by the physiological consequences of a substance (e.g., drug misuse, medication, or other treatment) or a medical condition (e.g., hyperthyroidism).
The severity of the symptoms cannot be explained by normal menstrual physiology.
Generalized anxiety disorder and depression are improbable diagnoses because these symptoms are temporally tied to menstrual cycles.

TSH, FSH, LH and HCG are all similar glycoproteins. These hormones consist of a common α-subunit and specific β-subunit. All are glycosylated, which determines their bioactivity and half-life.

Fetal urine contributes significantly to amniotic fluid production in the second trimester of pregnancy. As early as 8-11 weeks, urine production begins and can be observed in the fetal bladder on ultrasound scans. The urine creates a hypotonic fluid which contains increasing concentrations of urea and creatinine. By term, a foetus produces about 800 ml of urine a day, of which 250ml is eliminated through fetal swallowing.

Congenital uterine abnormalities are associated with an increased risk of spontaneous abortions, preterm delivery of the foetus, fetal growth retardation and malpresentation.

P wave = Atrial depolarisation
QRS complex = Ventricular depolarisation
T wave = Ventricular repolarisation
U wave = repolarisation of the interventricular septum

This is a patient that recently gave birth and is still breastfeeding presenting with dyspareunia. The most likely cause would be a thin atrophic vaginal epithelium. This is very common presentation and is due to the low oestrogen levels due to the prolactin elevation from breastfeeding.

An unrecognised and unsutured vaginal tear should have healed by this time and should not be causing issues.

Endometriosis tends to resolve during a pregnancy, but if this was the issue, it would have caused dyspareunia prior to pregnancy.

Vaginal infective causes of dyspareunia, such as monilial or trichomonal infections, are rare in amenorrhoeic women.

Face presentation is the abnormal position of the fetal head in labour. In this position the neck is hyperextended.
Vertex position is the normal presentation of the foetus for delivery, in which the head is flexed and the position of the chin is towards the chest.

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.

There are many different reasons for performing a delivery by Caesarean section. The four major indications accounting for greater than 70 per cent of operations are: 1. previous Caesarean section 2. dystocia 3. malpresentation 4. suspected acute fetal compromise. Other indications, such as multifetal pregnancy, abruptio placenta, placenta praevia, fetal disease and maternal disease are less common. The chances of early postpartum haemorrhage are greatly reduced in C-section deliveries.

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).

Vulvovaginal candidiasis is the most common genital infections and it is caused by candida albicans in 80-92% of the cases. It colonise the vaginal flora in 20% of non pregnant and 40% pregnant women.

Uterus is lines by a single layer of columnar epithelium. The endometrium goes through changes during the menstrual cycles.

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.

The maternal mortality rate starts low and raises steeply after the age of 30 years. The lowest mortality rate recorded among women is between 19-30 years of age group.

The following treatment regimes are recommended for the treatment of Chlamydia in Pregnancy: Erythromycin 500mg four times a day for 7 days or Erythromycin 500 mg twice a day for 14 days or Amoxicillin 500 mg three times a day for 7 days or Azithromycin 1 gm stat (only if no alternative, safety in pregnancy not fully assessed) The following treatment regimes are recommended for the treatment of Chlamydia in NON-PREGNANT patients: Doxycycline 100mg bd for 7 days OR Azithromycin 1gm orally in a single dose NOTE: Doxycycline and Ofloxacin are contraindicated in pregnancy

First trimester abortions are performed using mifepristone 600 mg followed by insertion of 1 mg gemeprost vaginal pessary. The patients stays in the hospital for about 4-6 hours. At the time of abortion azithromycin 1 g and metronidazole 800 mg should be given to cover the gram positive and negative bacteria.

The best next step is to order an ultrasound of the pelvis to locate the IUCD in the uterine cavity.

Once the device is located, appropriate advice can be given about the pregnancy proceeding.

Uterine sounding and hysteroscopy are contraindicated in the presence of a viable pregnancy due to risks of infection and abortion.

Pelvic X-ray is indicated if the device cannot be located during the pelvic ultrasound. It can show if the device is in the peritoneal cavity or has been expelled from the uterus. It should only be done after the pregnancy.

In cases where the device is in the peritoneal cavity, a laparoscopy is indicated for device removal.

Pregnancy termination is not indicated simply because of the presence of an intrauterine device (IUCD) in the uterus, unless other factors dictate that this is appropriate.

First stage: The latent phase is generally defined as beginning at the point at which the woman perceives regular uterine contractions. A definition of active labour is having contractions more frequent than every 5 minutes, in addition to either a cervical dilation of 3 cm or more or a cervical effacement of 80% or more.

Second stage: fetal expulsion begins when the cervix is fully dilated, and ends when the baby is born.

Third stage: placenta delivery – The period from just after the foetus is expelled until just after the placenta is expelled is called the third stage of labour or the involution stage.

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.

The round ligament is a remnant of the gubernaculum in females. In males it persists as the scrotal ligament.

Bacterial Vaginosis is a common condition which results in a foul smelling discharge from the vagina without any inflammation. It is the most common cause of abnormal PV discharge. Most of the women are asymptomatic carriers.

The use of long-acting reversible contraceptives (LARCs) is globally accepted as a strategy that is successful in decreasing rates of unintended pregnancy, especially in very young women.
Long-acting reversible contraceptives (LARCs) are defined as any contraceptive that requires administration less than once per cycle (i.e. per month). This includes copper and progestogen-only intrauterine devices (IUDs), and progestogen subdermal implants and injections. However, subdermal implants and IUDs, which have a life of at least three years, have superior efficacy over injections, which require administration every three months. Implants and IUDs are highly cost-effective when compared with other contraceptive methods.

LARCs are widely recommended by professional bodies and the World Health Organization (WHO) as first-line contraception for young women as they are safe, effective and reversible. Young women should be offered the choice of a LARC as part of a fully informed decision for their first form of contraception.

LARCs surpass barrier methods and contraceptive pills in effectiveness and safety therefore all other options are incorrect.

Adenomyosis or dysfunctional uterine haemorrhage are the most likely causes of heavy periods.
Because she refuses to have a hysterectomy or endometrial ablation, hormonal therapy must be administered in addition to the iron therapy she is already receiving.
Any of the choices could be employed, but using therapy only during the luteal phase of the cycle in someone who is virtually surely ovulating (based on her typical monthly cycles) is unlikely to work.

Danazol is prone to cause serious adverse effects (virilization), especially when used for a long period of time.
GnRH agonists would cause amenorrhoea but are more likely to cause substantial menopausal symptoms, and the °fa contraceptive pill (OCP) is generally best avoided in someone using hypertension medication.

Treatment with norethisterone throughout the cycle is likely to be the most successful of the treatments available.
If a levonorgestrel-releasing intrauterine device (Mirena®) had been offered as an alternative, it would have been acceptable.

There is a high risk of developing HELLP syndrome in pre-eclamptic patients. Considering that she is complaining of right upper quadrant pain, a LFT should be done immediately.

Gestational trophoblastic disorder is abnormal conception that is characterised by swollen and oedematous villi with proliferation of the trophoblasts. In a complete mole there is absence of fetal tissue, there is diffuse proliferation of trophoblastic tissue around hydropic villi and on USG it appears as a bunch of grapes or snow storm appearance.

At 12 weeks gestation the fundus is expected to be palpable above the pubis symphysis and it is expected to be felt at the level of umbilicus by 20 weeks. Though the uterine fundus stands in between from 12 and 20 weeks, the height of the fundus in centimeters is equivalent to the weeks of pregnancy after 20 weeks.

For 14-week pregnant uterus a fundal height of 18cm is definitely large and dating errors is considered as the most common cause for such a discrepancy. Hence, it is better to perform an ultrasound scan for more accurately estimating the gestational age. Also if the case is not a simple dating error, ultrasonography can provide definitive additional information about other possible conditions such as polyhydramnios, multiple gestation, etc that might have led to a large-for-date uterus.

A large-for-gestational-age uterus are most commonly found in conditions like:
– Dating errors which is the most common cause
– Twin pregnancy
– Gestational diabetes
– Polyhydramnios
– Gestational trophoblastic disease, also known as molar pregnancy
