Turner syndrome is the clinical diagnosis for this patient. Turner syndrome affects women who are lacking all of one X chromosome (45, characterized by X gonadal dysgenesis).
Turner Syndrome is characterized by small stature and non-functioning ovaries, resulting in infertility and lack of sexual development. Other sexual and reproductive organs (uterus and vagina) are normal despite the inadequate or missing ovarian activity.

Webbing of the neck, puffy hands and feet, coarctation of the aorta, and cardiac anomalies are all physical symptoms of Turner Syndrome. Streak gonads are also a feature of Turner syndrome.

The ovaries are replaced with fibrous tissue and do not produce much oestrogen, resulting in amenorrhea.

Until puberty, when oestrogen-induced maturation fails, the external female genitalia, uterus, and fallopian tubes develop normally.

Neisseria Gonorrhoeae is a Gram negative diplococci.

X-rays carry low levels of risk during pregnancy and are not a significant cause for concern if the total exposure to ionising radiation is less than 5 rads throughout the pregnancy; a chest X-ray is about 0.00007 rads. The amount of radiation generated from a chest X-ray is equivalent to 2.4 days of natural background radiation. Non-urgent radiological tests should, however, be avoided between 10-17 weeks gestation as there is a higher risk of central nervous system teratogenesis during this time.

Hyperemesis Gravidarum effects around 0.3-2% of Pregnancies. It causes imbalances of fluid and electrolytes, disturbs nutritional intake and metabolism, causes physical and psychological debilitation and is associated with adverse pregnancy outcome, including an increased risk of preterm birth
and low birthweight babies. The aetiology is unknown however various potential mechanisms have been proposed including an association with high levels of serum human chorionic gonadotrophin (hCG), oestrogen and thyroxine.

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.

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.

LH surge occurs around ovulation and it is this LH surge which results in completion of the 1st meiotic division and ovulation occurs. It enhances the production of androgens and also luteinizes the granulosa cells.

Gestational Diabetes occurs in 2-9% of all the pregnancies.

Screening for gestational diabetes should be offered and performed between 24-28 weeks. It should be noted PCOS alone does not make screening essential. It is advised for PCOS patients who are overweight or if not overweight but has other risk factors (age >40, personal history of gestational diabetes or family history of type II diabetes). Screening is via a 2-hour post 75 g oral glucose tolerance test.

Monozygotic (MZ) twins originate when a single egg is fertilized to form one zygote, which then divides into two embryos. Although they share the same genotype they are not phenotypically identical.

Miscarriage rates:
20-24 – 9%
25-29 – 11%
30-34 – 15%
35-39 – 25%
40-44 – 51%
>45 – 75%

Cervical ectropion occurs when glandular cells develop on the outside of the cervix. Many individuals with cervical ectropion do not experience symptoms.
However, the primary symptom of cervical ectropion is a red, inflamed patch at the neck of the cervix.
The transformation zone appears this way because the glandular cells are delicate and irritate easily.
Other symptoms a woman may experience include:
pain and bleeding during or after sex
pain during or after cervical screening
light discharge of mucus
spotting between periods
Symptoms may range from mild to severe when they appear.

This patient has normal pap smear and is unlikely to have cervical cancer. She has no fever and vaginal discharge which would be the presentation of Chlamydia infection.

Endometrial cancer affects mainly post menopausal women and presents with vaginal bleeding, weight loss, dysuria and dyspareunia.

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.

Shortly after the Morula enters into the uterus, approximately on the 4th day after fertilization a fluid filled cystic cavity appears in the morula and transforms the morula into a blastocyst.

Progesterone gradually increases during the course of pregnancy, from 25 ng⋅mL−1 at 6 weeks’ to 150 ng⋅mL−1 at 37 weeks’ gestation. Progesterone acts as trigger of the primary respiratory centre by increasing the sensitivity of the respiratory centre to carbon dioxide, as indicated by the steeper slope of the ventilation curve in response to alveolar carbon dioxide changes. Progesterone alters the smooth muscle tone of the airways resulting in a bronchodilator effect. It also mediates hyperaemia and oedema of mucosal surfaces, causing nasal congestion.

The risk of developing endometrial carcinoma is less than 5% over 20 years if the endometrium shows hyperplasia without atypia.
There are 2 types of Endometrial Hyperplasia:
1. Hyperplasia without atypia*
2. Atypical hyperplasia

Major Risk Factors:
Oestrogen (HRT)
Tamoxifen
PCOS
Obesity
Immunosuppression (transplant)

Ovulation usually occurs on day 14 in a typical 28-day cycle. Luteinizing hormone levels spike as a result of increased oestrogen levels secreted from maturing follicles. This LH spike occurs about 24-36 hours before the release of the oocyte from the mature follicle.

Stress incontinence is characterized by the involuntary loss of urine with increases in intra-abdominal pressure. It is the most common type of incontinence in younger women, but also occurs in older women. Key risk factors include childbirth, medications that relax the urethral sphincter, obesity, lung disease (from chronic cough), and prior pelvic surgeries. Numerous treatments are available, although few studies compare one treatment with another.

Pelvic floor muscle exercises are the mainstay of behavioural therapy for stress incontinence. Up to 38 percent of patients with stress incontinence alone who follow a pelvic floor muscle exercise regimen for at least three months experience a cure.

Routine urodynamic tests are not recommended for urinary incontinence. Surgery is reserved for refractory incontinence.

Oxytocin binds to the G protein coupled receptors that triggers the IP3 mechanism leading to an elevated intracellular calcium ion.

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.

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

Diastolic murmurs should be considered pathological until proven otherwise. The following are common and typically benign findings in pregnancy: A third heart sound after mid-pregnancy. Systolic flow murmurs are common. Left axis deviation on ECG is common, Sagging ST segments and inversion or flattening of the T wave in lead III may also occur

An ovarian cyst is a sac filled with liquid or semiliquid material that arises in an ovary. Although the discovery of an ovarian cyst causes considerable anxiety in women owing to fears of malignancy, the vast majority of these lesions are benign.

Many patients with simple ovarian cysts based on ultrasonographic findings do not require treatment.
In a postmenopausal patient, a persistent simple cyst smaller than 10cm in dimension in the presence of a normal CA125 value may be monitored with serial ultrasonographic examinations.

However, meta-analyses have since shown that there is no difference between OCP use and placebo in terms of treatment outcomes in ovarian cysts and that these masses should be monitored expectantly for several menstrual cycles.

If a cystic mass does not resolve after this timeframe, it is unlikely to be a functional cyst, and further workup may be indicated.

Other methods of management maybe revisited if cyst increases in size or becomes complex upon follow up.

Combined oral contraceptives are a safe and highly effective method of birth control, but they can also raise problems of clinical tolerability and/or safety in migraine patients. It is now commonly accepted that, in migraine with aura, the use of combined oral contraceptives is always contraindicated, and that their intake must also be suspended by patients suffering from migraine without aura if aura symptoms appear.

Discontinuation of contraception could risk in pregnancy. Barrier methods can be used but aren’t as effective as pills.

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 drug of choice for eclampsia and pre-eclampsia is magnesium sulphate. It is given as a loading dose of 4g i/v over 5 minutes, followed by an infusion for the next 24 hours at the rate of 1g/hr. If the seizures are not controlled, an additional dose of MgSO4 2-4gm i/v can be given over five minutes. Patients with eclampsia or pre-eclampsia can develop any of the following symptoms: persistent headache, visual abnormalities like photophobia, blurring of vison or temporary blindness, epigastric pain, dyspnoea and altered mental status.

1. First-degree trauma corresponds to lacerations of the skin/vaginal epithelium alone.
2. Second-degree tears involve perineal muscles and therefore include episiotomies.
3. Third-degree extensions involve any part of the anal sphincter complex (external and internal sphincters):
i Less than 50 per cent of the external anal
sphincter is torn.
ii More than 50 per cent of the external anal
sphincter is torn.
iii Tear involves the internal anal sphincter
(usually there is complete disruption of the
external sphincter).
4. Fourth-degree tears involve injury to the anal sphincter complex extending into the rectal mucosa.

it is imperative to elucidate the patient’s risk for current pregnancy and time within her current menstrual cycle prior to IUD insertion. A negative urine pregnancy test is a prerequisite to placement of an IUD. Pregnancies occurring with IUDs in place have an increased incidence of complications, including spontaneous abortion and septic abortion.

For this reason, many providers prefer to time IUD insertion within the first 5-7 days of the menstrual cycle, further assuring that the patient is not newly pregnant.

All other options take risk of the patient being pregnant.

Turner syndrome patients have malfunctioning or streak ovaries due to which they can never conceive. It affects females, who will have a short stature, widely spaced nipples, webbed neck and karyotyping shows 45XO.

According to the WHO, active management of the third stage of labour has been shown to decrease the risk of postpartum haemorrhage in vaginal births worldwide. Per the guidelines from the International Federation of Gynaecologists and Obstetricians (FIGO), the active management of the third stage is summarised as follows:
1. The administration of a uterotonic (oxytocin, ergometrine or misoprostol), within one minute of fetal delivery,
2.Controlled cord traction with manual support to the uterus until placental delivery
3. Fundal massage immediately after placental delivery.

The luteinizing hormone (LH) surge during ovulation causes: Increases cAMP resulting in increased progesterone and PGF2 production PGF2 causes contraction of theca externa smooth muscle cells resulting in rupture of the mature oocyte

To help protect babies during this time when they are most vulnerable, women should get the tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis vaccine (Tdap) during each pregnancy.

Pregnant women should receive Tdap anytime during pregnancy if it is indicated for wound care or during a community pertussis outbreak.
If Tdap is administered earlier in pregnancy, it should not be repeated between 27 and 36 weeks gestation; only one dose is recommended during each pregnancy.

Optimal timing is between 27 and 36 weeks gestation (preferably during the earlier part of this period) to maximize the maternal antibody response and passive antibody transfer to the infant.
Fewer babies will be hospitalized for and die from pertussis when Tdap is given during pregnancy rather than during the postpartum period.

The patient could be suffering from pre-eclampsia. A BP of 140/100 with proteinuria should be admitted immediately for observation and if the symptoms do not improve then managed immediately. According to the NICE guidelines BP should be monitored 4 times daily. A BP of 140/90 to 149/99 mmHg is classed as mild hypertension. Without proteinuria this can be monitored once weekly and the patient can be discharged.

A ruptured ectopic pregnancy is the most probable diagnosis. As she is in shock (tachycardia and hypotension) immediate laparotomy is needed.

The amniotic fluid volume increases up to week 35 of gestation and then decreases from then to term.

This describes the sensory area supplied by the ilioinguinal nerve. This is a potential complication with pelvic surgery.

Second-trimester ultrasound markers have low sensitivity and specificity for detecting Down syndrome, especially in a low-risk population.

The highest detection rate is acquired with ultrasound markers combined with gross anomalies. Although the detection rate with this combination of markers is high in a high-risk population (50 to 75 percent), false-positive rates are also high (22 percent for a 100 percent Down syndrome detection rate).

Detrusor overactivity can be treated with anti-cholinergic agents such as oxybutynin or tolterodine, solifenacin, fesoterodine and darifenacin. They are used as first line agents. Imipramine is used for enuresis and desmopressin is used for nocturia.
NICE pathway

Prior to initiating anticholinergics:
Bladder training
Consider treating vaginal atrophy and nocturia with topical oestrogen and desmopressin respectively before commencing treatments below.
Consider catheterisation if chronic retention
1st line treatments:
1. Oxybutynin (immediate release) – Do not offer to frail elderly patients
2. Tolterodine (immediate release)
3. Darifenacin (once daily preparation)
DO NOT offer any of the 3 drugs below:
1. Flavoxate
2. Propantheline
3. Imipramine
2nd line treatment
Consider transdermal anticholinergic (antimuscarinic)
Mirabegron
Adjuvant Treatments
Desmopressin can be considered for those with nocturia
Duloxetine may be considered for those who don’t want/unsuitable for surgical treatment
Intravaginal oestrogen can be offered to postmenopausal women with OAB

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

The bladder is supplied by branches of the internal iliac artery, including the superior vesical artery, branches of the gluteal and obturator arteries and the inferior vesical artery in males and the vaginal and the uterine arteries in females.

Chorioamnionitis is a complication of pregnancy caused by bacterial infection of the fetal amnion and chorion membranes. Group B Streptococcus is associated with chorioamnionitis

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

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

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

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 in a British journal was 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.

The best next step in her management is a colposcopy.

Patients diagnosed with high-grade lesions (CIN 2 or 3) or adenocarcinoma in situ (AIS) during pregnancy should undergo surveillance via colposcopy and age-based testing (cytology/HPV) every 12-24 weeks.

Cone biopsy and long loop excision of the transformation zone (LLETZ biopsy) are not recommended if the lesion extends up the canal and out of the vision of the colposcope.
It is not necessary to terminate the pregnancy.

Because repeat colposcopic examination during pregnancy offers all of the information needed, the repeat Pap smear is best done after the pregnancy has ended.

Unless colposcopy indicates aggressive cancer at an earlier time, the ultimate therapy required is usually not decided until the postpartum visit.

Most carcinomas spread primarily via lymphatic invasion. Renal cell is the exception spreading via the bloodstream.

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%).

Remember the inferior rectal artery supplies the anus. The middle rectal artery is the principle supply to the lower 1/3 rectum. The rectal arteries do form an anastomosis.

Gonadotropin-releasing hormone (GnRH) is the hormone responsible for the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) from the anterior pituitary gland.

The pudendal nerve provides sensory innervation to regions of the anus, the perineum, the labia and the clitoris in women. The nerve is formed from the ventral rami of the S2-S4 sacral spinal nerves. The nerve is paired, each innervating the left and the right side of the body. Pudendal nerve blocks are indicated for analgesia of the second stage of labour, repair of an episiotomy or perineal laceration, and for minor surgeries of the lower vagina and perineum.

In this pregnant patient with an antepartum haemorrhage at 37 weeks of gestation, her clinical presentation points to a placenta previa. Her bleeding has stopped, the uterus is of the expected size and non-tender, and the fetal head is still mobile above the pelvic brim which are all findings that would be consistent with a placenta praevia. An ultrasound examination would be done to rule-out or diagnose the condition.

An Apt test on the blood is necessary to ensure that this is not fetal blood that would come from a ruptured vasa praevia. Although this diagnosis would be unlikely since the bleeding has stopped. If there was a vasa praevia, there would be fetal tachycardia or bradycardia, where a tachycardia is often seen first but then bradycardia takes over late as fetal exsanguination occurs.

In a placental abruption with concealment of blood loss, the uterus would be larger and some uterine tenderness would be found on exam.

A cervical polyp could bleed after sexual intercourse and a speculum examination would be done to exclude it. However, it would be unlikely for a cervical polyp to cause such a large amount of blood loss. A heavy show would also rarely have as heavy as a loss of 200mL.

Fibrinogen is activated by thrombin which converts it into fibrin which forms a mesh to trap red blood cells and form a clot.

The arches are numbered according to their proximity to the head i.e. the 1st is the closest to the head end of the embryo and the 6th closest to the tail end as shown by the diagram below the table

Chorion villus sampling is an invasive procedure which aims to collect the rapidly dividing cells in the placenta. It is used for numerous reasons including detection of early pregnancy, viability of the foetus, singleton pregnancy, confirm gestation age and for prenatal diagnosis of the fetal chromosomal abnormalities including diagnosis of Down’s syndrome. However it hold a 2% chance of miscarriage during the procedure. Nuchal thickness and imaging are part of the combined test that must have been performed before.

Mirena is a form of contraception also indicated for the treatment of heavy menstrual bleeding and the management of dysmenorrhea, being able to reduce the latter considerably.

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

Miscarriage is a pregnancy that ends spontaneously before the foetus reaches the age of viability i.e. before 24 weeks of gestation. In a threatened miscarriage the USG findings are of a foetus present in the uterus and on speculum examination the cervical OS is closed, in an inevitable miscarriage the cervical OS is opened. In an incomplete miscarriage the uterus contains the retained products of conception and the cervical OS is open. complete miscarriage contains no retained products of conception and the cervix is closed as the bleeding as resolved.

This lady should be admitted to hospital for early surgical exploration. Taking into account her age, mild abdominal discomfort and a palpable lower abdominal mass, it is imperative that ovarian malignancy be ruled out as soon as possible. Patients with ovarian malignancy often present in advanced stages of cancer as the symptoms tend to be occult and non-specific. Other things to include in her workup would be her CA125 level. Any form of hormonal therapy is contraindicated until ovarian malignancy has been ruled out. A pap smear is not relevant here since we are suspecting an ovarian malignancy rather than cervical. Evaluation of her mass takes priority over an assessment for osteoporosis.

The clinical evaluation indicates that the patient is ovulating but has not started menstruating. These observations suggest that the pain she is experiencing on a monthly basis could be related to ovulation or there could be an obstruction preventing the flow of menstrual blood from the uterus.

Uterine or vaginal anomalies that can obstruct menstrual flow include imperforate hymen, absent vagina, a transverse vaginal septum, or cervical obstruction.

If the cause was an obstruction to the flow, the retained menstrual products would have developed into a suprapubic mass (hematometra/ haematocolpos). However, no palpable mass was detected on abdominal examination.

Mullerian (paramesonephric) agenesis (correct answer) is the only condition that would result in no endometrial development; consequently there was no palpable mass observed and no menstrual loss that could be shed was present. A pelvic (lower abdominal) ultrasound examination can confirm the diagnosis.

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

There is marked elevation of FSH and LH in ovarian dysgenesis, produced by the pituitary.

There are several criteria that aid in the diagnosis of gestational diabetes in pregnancy including NICE, WHO and modified WHO:
GDM Diagnostic Criteria:
NICE: Immediate FBG >5.6, 2 hour glucose >7.8
WHO: Immediate FBG >6.1, 2 hour glucose >7.8
Modified WHO: Immediate FBG >7.1, 2 hour glucose >7.8

Random glucose and OGTT 2 hour readings of >11.1 are diagnostic of diabetes in non-pregnant states but are not part of the gestational diabetes criteria.

Menorrhagia in a 45-year-old woman is most likely caused by an ovulation issue, most likely anovulatory cycles, particularly if the periods have grown irregular.

Endometrial carcinoma is a rare cause of menorrhagia that usually occurs after menopause.

Menorrhagia can be caused by fibroids, endometrial polyps, and adenomyosis, although the cycles are normally regular, and a dramatic change from normal cycles six months prior would be exceptional.
If fibroids or adenomyosis are the source of the menorrhagia, the uterus is usually enlarged.

This woman suffers from a classic migraine with focused neurological symptoms. The use of any OCP preparation containing oestrogen in such patients is strictly prohibited. Androgenic consequences of progesterone include hirsutism, acne, and weight gain. Progesterone of any sort (norgestrel, drospirenone, cyproterone, etc.) should be avoided by a lady of her size; consequently, a barrier approach such as male condoms is the best option.

It is recommended that formulations containing 20-30 mcg ethinylestradiol be evaluated first when choosing a combined oral contraceptive pill (COCP). The progesterone component can be norgestrel, drospirenone, cyproterone, and so on; however, norgestrel-containing formulations are less expensive and more accessible to patients.

For specific cases, the type of progesterone should be considered:
– Patients who have unpleasant fluid retention and weight gain as a side effect of COCPs may be administered drospirenone (Yaz®. Yasmin®)-containing preparations.
– Drospirenone inhibits the production of mineralocorticoids and does not cause fluid retention. It may even be linked to a small amount of weight reduction.
– A preparation containing cyproterone acetate is preferable if the patient has suspected polycystic ovarian syndrome (PCOS).

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.

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.

Elements of the Apgar score include colour, heart rate, reflexes, muscle tone, and respiration. Apgar scoring is designed to assess for signs of hemodynamic compromise such as cyanosis, hypoperfusion, bradycardia, hypotonia, respiratory depression or apnoea. Each element is scored 0 (zero), 1, or 2. The score is recorded at 1 minute and 5 minutes in all infants with expanded recording at 5-minute intervals for infants who score 7 or less at 5 minutes, and in those requiring resuscitation as a method for monitoring response. Scores of 7 to 10 are considered reassuring.

CVS has decreased in frequency with the recent increased uptake of cell-free DNA screening. It remains the only diagnostic test available in the first trimester and allows for diagnostic analyses, including fluorescence in situ hybridization (FISH), karyotype, microarray, molecular testing, and gene sequencing. CVS is performed between 10 and 14 weeks’ gestation. CVS has been performed before 9 weeks in the past, though this has shown to increase the risk of limb deformities and, therefore, is no longer recommended.

Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects. Streak ovaries are a form of ovarian dysgenesis and are associated with Turner syndrome. Occasionally they may be functional and secondary sexual characteristics may develop.

The most appropriate test for a hydatiform mole is serum beta hCG levels, which are consistently raised in these patients. The levels return to normal when the pregnancy is terminated.

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

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

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

In Cushing’s syndrome there is excess cortisol. Causes are broadly divided into 2 types: ACTH dependent disease: excess ACTH from the pituitary (Cushing’s disease), ectopic ACTH-producing tumours or excess ACTH administration. Non-ACTH-dependent: adrenal adenomas, adrenal carcinomas, excess glucocorticoid administration. The recommended diagnostic tests for the presence of Cushing’s syndrome are 24-hour urinary free cortisol, 1 mg overnight dexamethasone suppression test and late-night salivary cortisol. There are several other tests that may also be performed to find the cause. ACTH and cortisol measured together may show if this is ACTH dependent or not. MRI pituitary and CT abdo and pelvis may show if tumour is the cause.

This patient has experienced polycystic ovarian syndrome-like symptoms.
At least two out of three of the following criteria must be met to diagnose polycystic ovarian syndrome:
1- Hyperandrogenism suggesting an excess of androgens e.g. excess hair growth, acne etc.
2- Menstrual irregularities e.g. dysmenorrhea, oligomenorrhea, and amenorrhea.
3-The ovaries are polycystic if one ovary has 12 or more follicles or if the size of one or both ovaries has risen.

Low FSH, LH, and pituitary hormones are typically associated with hypothalamic dysfunction, however this is not the case here.
Similarly, with premature ovarian failure, FSH/LH levels rise while oestrogen levels decrease.

All of the other choices are incorrect.

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.

Hormones that increase during pregnancy and their roles:

1. Human Chorionic Gonadotropin (hCG): Peaks between the eighth to tenth weeks of gestation and supports the corpus luteum to maintain progesterone production.
2. Progesterone: Initially produced by the corpus luteum and later by the placenta, it rises steadily throughout pregnancy, suppressing the maternal immune response to fetal antigens and preparing the endometrium for implantation.
3. Estrogen: Produced by the placenta from fetal and maternal precursors, estrogen levels increase to promote uterine growth and blood flow.
4. Human Placental Lactogen (hPL): Rises significantly during pregnancy, influencing maternal metabolism by increasing insulin resistance and promoting lipolysis.
5. Relaxin: Increases early in pregnancy to relax the uterine muscles, inhibit contractions, and prepare the cervix and pelvis for childbirth.
6. Prolactin: Levels increase to prepare the breasts for lactation.
7. Corticotropin-Releasing Hormone (CRH): Increases towards the end of pregnancy and is involved in the timing of labor.
8. Adrenocorticotropic Hormone (ACTH): Levels increase, contributing to elevated cortisol levels during pregnancy.
9. Total Thyroxine (T4): Levels increase due to elevated thyroid-binding globulin (TBG) production stimulated by increased estrogen levels, meeting the increased metabolic demands of pregnancy.
10. Parathyroid Hormone (PTH): Levels increase to regulate calcium metabolism, ensuring adequate calcium for fetal bone development.
11. Cortisol: Levels increase due to higher production by the adrenal glands and increased binding to cortisol-binding globulin (CBG), supporting glucose metabolism, managing stress, and aiding fetal development, particularly lung maturation.

During pregnancy, some hormones either remain stable or do not increase significantly. These include:

1. Follicle-Stimulating Hormone (FSH): Levels decrease due to the negative feedback from high levels of estrogen and progesterone.
2. Luteinizing Hormone (LH): Levels also decrease due to negative feedback from elevated estrogen and progesterone.
3. Growth Hormone (GH): Although a variant of growth hormone (hGH-V) is produced by the placenta and increases, the maternal pituitary GH levels may not significantly increase.
4. Melatonin: Generally remains stable during pregnancy, though some studies suggest there may be slight fluctuations.
5. Insulin: While insulin resistance increases due to hPL and other factors, the actual levels of insulin may not increase proportionally; instead, pancreatic beta-cell function adapts to meet the increased demand.

Endometrial cancer is one of the most common gynaecological malignancies present in postmenopausal women, with a peak incidence between the ages of 60-89. Factors associated with endometrial cancer include obesity, hypertension and diabetes. Full staging for endometrial cancer is surgical, including several other radiologic investigations. According to FIGO staging classifications:
Stage 1 indicates a tumour confined to the uterine body
Stage 2 indicates the invasion of the cervical stroma
Stage 3 indicates local and regional spread, where the tumour invades the serosa in stage 3A, spreads to the vagina and parametrium in stage 3B, and metastasizes to the pelvic or para-aortic lymph nodes in stage 3C.
Stage 4 indicates tumour invasion on the bladder or bowel mucosa, or distant metastasis.

Oral progestogen therapy for 21 days (day 5-26) is considered effective but is only a short-term therapy for menorrhagia. Myomectomy should only be considered if the woman would like to conceive later on. Due to the recurrent nature of fibroids, it is likely that the woman would need more surgeries in the future, which is not ideal. Furthermore, if there is a large number of fibroids or the size of the fibroids are large, myomectomy would not be an option for reasons such as the feasibility. If myomectomy for multiple fibroids prove to be unsuccessful, the ultimate outcome would still have to be a hysterectomy.

In cases where there is significant enlargement of the uterus, endometrial ablation would be difficult and the long-term cure rate of symptoms would be considerably low. The best next step would be a total abdominal hysterectomy since it would solve her menorrhagia and within a few years’ time, she would be expected to attain menopause anyway. Ponstan or mefenamic acid has been found to be superior to tranexamic acid for menorrhagia. However, it can still prove to be ineffective in some cases and also not a long term solution.

Cohort studies are the most appropriate study design to study the prognosis of a disease. A group of patients with the same condition are chosen and their baseline information is taken. The group is then followed up over time to see which patients live or die.
Case-control studies can also be useful where a group of individuals that have survived a condition are compared with cases of those who have died. Prognostic factors that distinguish the two groups are identified. This method, however, is limited by bias and the accuracy of medical information present.

Gas gangrene is synonymous with myonecrosis and is a highly lethal infection of deep soft tissue, caused by Clostridium species, with Clostridium perfringens being the most common. This organism has also had increased incidence as the cause of deep tissue infections associated with childbirth and infections after gynaecologic procedures including septic abortions, which can cause gas gangrene of the uterus.
Health care workers should suspect gas gangrene if anaerobic gram-positive bacilli are present in a wound with necrosis of soft tissue and muscle. The organisms produce a gas identifiable on x-ray or CT scans.
Patients with gas gangrene (myonecrosis) present with signs of infection such as fever, chills, pain, and less superficial inflammation at the site of infection than one would expect given the deep penetrating nature of these infections. The condition of the patient can rapidly progress to sepsis and death if not treated aggressively. The wound discharge is often dishwater looking with a musty order.

Choriocarcinoma may arise as a complication of gestation or as spontaneous germ cell tumours. As this scenario depicts that the women has previous abortion points to the fact that these may have been molar pregnancies. As choriocarcinoma can arise from a molar pregnancy it can be differentiated from it by the presence of invasion into the uterus and metastasis to the lungs primarily.

It is classified under type II hypersensitivity reaction. Antibodies are formed against the rhesus antigen i.e. D antigen. Hence when the Antibody reacts with the antigen on the RBC it results in activation of the complement cascade leading to lysis.

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.

Barr body is an inactive and non functioning X chromosome found in female somatic cells and is presents with a rim around the nucleus

Overflow incontinence typically presents with continuous urinary leakage or dribbling in the setting of incomplete bladder emptying. Associated symptoms can include weak or intermittent urinary stream, hesitancy, frequency, and nocturia. When the bladder is very full, stress leakage can occur or low-amplitude bladder contractions can be triggered resulting in symptoms similar to stress or urgency incontinence.

Women with urgency incontinence experience the urge to void immediately preceding or accompanied by involuntary leakage of urine

Individuals with stress incontinence have involuntary leakage of urine that occurs with increases in intraabdominal pressure (e.g., with exertion, sneezing, coughing, laughing) in the absence of a bladder contraction.

Early decelerations: a result of increased vagal tone due to compression of the fetal head during contractions. Monitoring usually shows a symmetrical, gradual decrease and return to baseline of FHR, which is associated with a uterine contraction.

Visual disturbances although very common during pregnancy are not a normal sign. Physicians should have a firm understanding of the various ocular conditions that might appear pregnancy or get modified by pregnancy. In addition, it is very important to be vigilant about the rare and serious conditions that may occur in pregnant women with visual complaints. Prompt evaluation may be required and the immediate transfer of care of the patient may help saving the lives of both the mother and the baby.

Hereditary breast cancers account for 10 % of the cases. BRCA gene mutations account for 25 % of these cancers.

This patient should be given promethazine and codeine as she presents with severe migraine.

Usage of metoclopramide is safe during pregnancy and for increasing effectiveness it can be added to paracetamol. However, because of its risk for causing extrapyramidal effects it should be used only as a second-line therapy and Promethazine should be considered as the first line choice of remedy. So the answer is Codeine and promethazine.

Opioid pain relievers such as codeine are not been reported of having any associated with increased birth defects or miscarriage, but its long-term use can lead to dependency in mother and withdrawal signs in the baby.

Paracetamol alone or combined with codeine is not found to be useful in controlling vomiting.

It is advised to completely avoid dihydroergotamine and the triptans throughout pregnancy.

When the palpated uterine size is in discrepancy with the expected size based on the duration of amenorrhoea, it can have several causes including reduced fluid volume or fetal growth (both of which are more common when there is fetal malformation), or miscalculated age of gestation as a result of wrong dates or actual ovulation occurring at a later date than expected. Reduced fluid volume and fetal growth are the most likely aetiologies during the third trimester of pregnancy, unlike in this patient at 20 weeks age of gestation.

Premature rupture of membranes is less likely the cause when there is negative vaginal fluid loss like this patient.

The most likely cause in this case is that ovulation did not occur as expected, especially when the patient ceased her OCPs during this period. In some instances, ovulation can occur 2 weeks later in about 50% of women, 6 weeks later in 90%, and may still not occur 12 months later in 1% of women.

The other listed statements are unlikely to explain the discrepancies in dates and the observed uterine size in this patient.

As there has been no bleeding or expulsion of the products of conception this is a missed miscarriage

The Bishop score is a system used by medical professionals to decide how likely it is that you will go into labour soon. They use it to determine whether they should recommend induction, and how likely it is that an induction will result in a vaginal birth.

Chorioamnionitis occurs due to prolong rupture of the fetal membranes. It is most commonly caused by B streptococcus.

Meconium first appears in the fetal ilium at 10-16 weeks.

Many patients with simple ovarian cysts based on ultrasonographic findings do not require treatment.
In a postmenopausal patient, a persistent simple cyst smaller than 10cm in dimension in the presence of a normal CA125 value may be monitored with serial ultrasonographic examinations.

Premenopausal women with asymptomatic simple cysts smaller than 8cm on sonograms in whom the CA125 value is within the reference range may be monitored, with a repeat ultrasonographic examination in 8-12 weeks.

Persistent simple ovarian cysts larger than 5-10 cm, especially if symptomatic, and complex ovarian cysts should be considered for surgical removal.

For this patient, a premenopausal woman, with an ovarian cyst size 8 cm x 12cm. Surgical management is indicated, hence referral to gynaecologist is appropriate.

Laparotomy or laparoscopic excision of cyst should be considered and performed by the gynaecologist not general practitioner.

High FSH and low E2 levels would be expected in menopause. FSH levels would be raised as her body attempts to stimulate ovarian activity and E2 would be low due to reduced ovarian function. The other options would be possible if she was younger, and if occurring with amenorrhea, would warrant further hormonal tests.

It is often challenging to interpret hormone test results close to the time of menopause, especially if the woman is still experiencing irregular menstruation, as remaining ovarian follicles might still produce oestrogen, causing both bleeding and FSH suppression. Elevation of FSH then can be seen again once the oestrogen level drops. Hence, the results would be influenced by the timing of blood sample collection. Once amenorrhea occurs more consistently, it would be easier to interpret the results.

The broad ligament is one of the secondary supporting structures of the uterus which attaches the lateral portion of the uterus to the pelvic sidewall. The broad ligament primarily serves a protective layer for important structures including the fallopian tubes, the ovaries, the ovarian arteries, and the uterine arteries, the round and ovarian ligaments, and the infundibulopelvic ligaments.

When face presentation is diagnosed, around 60% of cases are in the mentum anterior position, 25% are mentum posterior and 15% are mentum transverse; most malpositions rotate spontaneously into mentum anterior. A vaginal birth at term is possible only if the foetus is in the mentum anterior position.

There are a few differential diagnoses to think of in a patient that presents such as this one. Pre-eclampsia, cholecystitis, and fatty liver could all cause pain and tenderness, but cholecystitis would not normally cause the hypertension and proteinuria seen in this patient and neither would acute fatty liver of pregnancy. The more likely explanation is pre-eclampsia which must always be considered in the presence of these symptoms and signs. This process is particularly severe in the presence of pain and tenderness under the right costal margin due to liver capsule distension.

Chronic renal disease could cause the hypertension and mild proteinuria seen, but it would not usually produce the pain and tenderness that this patient has unless it was complicated by severe pre-eclampsia.

Biliary cholestasis does not usually produce pain.

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.

The clinical diagnosis of polycystic ovaries (PCO) is confirmed by the ultrasound. Therefore, the best next step to treat this woman’s infertility is to start treatment with metformin (correct answer). Patients with polycystic ovaries, frequently develop insulin resistance and metformin has been shown to be beneficial in this situation. Metformin treatment corrects any metabolic abnormalities and decreases insulin resistance resulting in a return of normal ovulatory menstrual cycles and a rapid improvement in fertility.

Additional treatment with clomiphene citrate may be required in some patients but gonadotrophin therapy is no longer commonly used.

Clomiphene citrate could also have been recommended as a possible next treatment option since the available data indicate that both clomiphene and metformin are equally effective.

Laparoscopic ovarian drilling has been used previously to treat polycystic ovaries; however, it is only used nowadays when all other treatment methods have been ineffective.

Similarly, gonadotrophin therapy or in vitro fertilisation would not be the best next step to treat the infertility and they are used when other treatment options have not provided the required results.

Even though changes in the semen analysis have been noted since the first pregnancy was achieved, these are not likely to be the cause of the secondary infertility, particularly because the current semen analysis is not significantly abnormal. Therefore, it is unlikely that donor insemination would be needed.
