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.

The Uterine artery typically arises from the anterior branch of the internal iliac artery. It crosses the ureter ANTERIORLY. It is the primary source of arterial supply to the uterus and its branches anastomose with branches of the ovarian and vaginal arteries.

The female pelvic inlet tilts at an inclination that is about 60 degrees from the anatomical horizontal plane. This tilt is maintained by muscles and fascia. The pelvic outlet slopes at an angle of 15 degrees.

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

Vaginismus is an uncontrollable painful spasm of the pelvic muscles and vaginal exit that this patient has. It’s mainly caused by psychological factors. It’s important to distinguish it from frigidity, which indicates a lack of sexual desire, and dyspareunia, which is characterized as pelvic and/or back pain or other discomfort linked with sexual activity. Endometriosis, pelvic adhesions, and ovarian neoplasms are all common causes of dyspareunia. Vaginismus pain can be psychogenic, or it might be caused by pelvic diseases like adhesions, endometriosis, or leiomyomas. Organic vulvar or pelvic reasons (such as atrophy, Bartholin gland cyst, or abscess) are extremely rare, hence vaginismus is mostly treated with psychotherapy.

Hegar’s sign: softening of womb (uterus) due to its increased blood supply, perceptible on gentle finger pressure on the neck (cervix). This is one of the confirmatory signs of pregnancy and is usually obvious by the 16th week.

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.

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

Workup:
Ultrasound

Treatment:
Asymptomatic: monitoring
Surgical intervention, hormonal contraception

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

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

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

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

Patients with a threatened abortion should be managed expectantly until their symptoms resolve. Patients should be monitored for progression to an inevitable, incomplete, or complete abortion. Analgesia will help relieve pain from cramping. Bed rest has not been shown to improve outcomes but commonly is recommended. Physical activity precautions and abstinence from sexual intercourse are also commonly advised. Repeat pelvic ultrasound weekly until a viable pregnancy is confirmed or excluded. A miscarriage cannot be avoided or prevented, and the patients should be educated as such. Intercourse and tampons should be avoided to decrease the chance of infection. A warning should be given to the patient to return to the emergency department if there is heavy bleeding or if the patient is experiencing light-headedness or dizziness. Heavy bleeding is defined as more than one pad per hour for six hours. The patient should also be given instructions to return if they experience increased pain or fever. All patients with vaginal bleeding who are Rh-negative should be treated with Rhogam. Because the total fetal blood volume in less than 4.2 mL at 12 weeks, the likelihood of fetal blood mixture is small in the first trimester. A smaller RhoGAM dose can be considered in the first trimester. A dose of 50 micrograms to 150 micrograms has been recommended. A full dose can also be used. Rhogam should ideally be administered before discharge. However, it can also be administered by the patient’s obstetrician within 72 hours if the vaginal bleeding has been present for several days or weeks.

The NICE guidelines on Hypertension in pregnancy define blood pressure in pregnancy as follows:
Mild hypertension: DBP=90-99 mmHg, SBP=140-149 mmHg. Moderate hypertension: DBP=100-109 mmHg, SBP=150-159 mmHg.
Severe hypertension: DBP=110 mmHg or greater, SBP=160 mmHg or greater.

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

In patients who have an HbA1C value above 10%, it is better to postpone pregnancy until diabetes is under control. Also in those patients with type 2 diabetes mellitus, who are suffering from severe gastroparesis, those with advanced retinopathy, with severe diabetic renal disease and severe ischemic heart disease with uncontrolled hypertension pregnancy is contraindicated.

All the other options mentioned are incorrect.

Anencephaly means the missing of a particular portion of the scalp and brain tissue. The other factors listed are associated with umbilical cord prolapse like multiparity, twin birth, polyhydramnios, premature delivery, long umbilical cord or breech presentation.

The pubic symphysis or symphysis pubis is the midline cartilaginous joint (secondary cartilaginous) uniting the superior rami of the left and right pubic bones. It is located anterior to the urinary bladder and superior to it.

6 and 11 are considered low risk and are commonly associated with genital warts and low-grade squamous intraepithelial lesions of the cervix (can correspond cytologically to CIN 1)

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.

Luteal phase occurs after the ovulation. Luteal defect means that the luteal phase is shorter than 10 days and women will find it difficult to sustain the pregnancy. There is decreased progesterone, LH and FSH production in this case.

Consideration of the risk of scar rupture is probably the most important consideration when determining whether delivery should be by elective Caesarean section or by trial of vaginal delivery.
Most published studies do not differentiate between scar dehiscence and rupture, however, analysis of observational and comparative studies indicates that the excess risk of uterine rupture following trial of labour compared with women undergoing repeat elective Caesarean section is considerably lower than 1 per cent (25/10000); indeed, some studies do not demonstrate any increased risk.

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.

Secondary postpartum hemorrhage of bright red character accompanied with fever, between 24 hours to 12 weeks of postpartum is suggestive of retained products of conception (RPOC).
The basal portion of the decidua may remain after separation of placenta in many cases. This decidua will then divides into two layers, the superficial layer which will be shed spontaneously and the deep layer which will regenerates and covers the entire endometrial cavity with in 16 days of postpartum.
Normal shedding of blood and decidua is referred to as lochia rubra, which is red / reddish brown in colour and it lasts for few days following delivery. This vaginal discharge gradually becomes watery and pinkish brown in colour, lasting for 2 to 3 weeks and is called as lochia serosa. Ultimately, this discharge becomes yellowish-white called as lochia alba.

Scanty lochia in the first few days after delivery is suggestive of the placental site not undergoing involution, which occurs mostly due to RPOC. Later these retained products will undergo necrosis resulting in fibrin deposition which will eventually form a placental polyp. Detachment of this scar of polyp will result in brisk hemorrhage and the remaining necrotic products will get infected resulting in uterine infection which will present with fever, lower abdominal pain and uterine tenderness.

Endometritis can lead to fever, offensive lochia and abdominal pain with tenderness. It is the most common cause of postpartum fever, but occurs within the first 5 days of postpartum with the peak incidence between days 2 and 3. Though vaginal bleeding is a presenting feature, bright red bleeding is unlikely of endometritis.

Another cause of postpartum fever is genital lacerations which have a peak incidence of wound infection between 4th and 5th days. Although fever as a temporal symptom favours wound infection, this diagnosis is less likely in the given case as wound infection will not affect the normal course of lochia, also it does not present as heavy bright red bleeding. Moreover, there are no symptoms like erythema, tenderness or discharge in history suggestive of wound infection.

Another cause of bleeding and fever can be cervical tear but this tends to present as primary postpartum hemorrhage rather than secondary, which occurs after 24 hours of postpartum. An overlooked and infected minor cervical laceration can cause fever but ii will not result in bright red bleeding, also genital tract lacerations do not affect lochia.

It is very unlikely for uterine rupture to occur 24 hours after delivery.

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

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

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

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

Tamoxifen and Raloxifene are drugs which acts as selective estrogen receptor modulators.
Their mechanisms of action are competitive inhibitor of estrogen binding and mixed agonist/antagonist action respectively.
Commonly indicated in prevention of breast cancer in high-risk patients. Tamoxifen as adjuvant treatment of breast cancer and Raloxifene in postmenopausal osteoporosis.
Adverse effects include:
– Hot flashes
– Venous thromboembolism
– Endometrial hyperplasia & carcinoma (tamoxifen only)
– Uterine sarcoma (tamoxifen only)
Adjuvant endocrine therapy is commonly used option for treatment of nonmetastatic, hormone-receptor-positive breast cancer; and the most commonly used endocrine agents include tamoxifen, aromatase inhibitors, and ovarian suppression via GnRH agonists or surgery.

Tamoxifen is a selective estrogen receptor modulator which is an estrogen receptor antagonist in the breast.  It is the most preferred adjuvant treatment for pre-menopausal women at low risk of breast cancer recurrence.  Tamoxifen is also a second-line endocrine adjuvant agent for postmenopausal women who cannot use aromatase inhibitor therapy due to intolerable side effects.
Tamoxifen acts as an estrogen agonist in the uterus and stimulates excessive proliferation of endometrium. Therefore, tamoxifen use is associated with endometrial polyps in premenopausal women, and endometrial hyperplasia and cancer in postmenopausal women. These effects will continue throughout the duration of therapy and resolves once the treatment is discontinued. Even with all these possible complications, benefits of tamoxifen to improve the survival from breast cancer outweighs the risk of endometrial cancer.

In postmenopausal women, tamoxifen has some estrogen-like activity on the bone, which can increase bone mineral density and thereby reduce the incidence of osteoporosis significantly.  However, tamoxifen is generally not a first-line agent for osteoporosis in treatment due to the marked risk of endometrial cancer.

Dysplasia of the cervical transformation zone is typically caused due to chronic infection by human papillomavirus, and tamoxifen has no known effects on the cervix.

Tamoxifen is not associated with any increased risk for adenomyosis, which is characterised by ectopic endometrial tissue in the myometrium.

Intimal thickening of the coronary arteries is a precursor lesion for atherosclerosis. Tamoxifen helps to decrease blood cholesterol level and thereby protect against coronary artery disease.

Tamoxifen is an estrogen antagonist on breast tissue and is used in the treatment and prevention of breast cancer, but it also acts as an estrogen agonist in the uterus and increases the risk of development of endometrial polyps, hyperplasia, and cancer.

Ventilation begins to increase significantly at around 8 weeks of gestation, most likely in response to progesterone-related sensitization of the respiratory centre to carbon dioxide and the increased metabolic rate. Significant alterations occur in the mechanical aspects of ventilation during pregnancy. Minute ventilation (or the amount of air moved in and out of the lungs in 1 minute) is the product of tidal volume and respiratory rate and increases by approximately 30–50 per cent with pregnancy. The increase is primarily a result of tidal volume, which increases by 40 per cent (from 500 to 700 mL), because the respiratory rate remains unchanged. The increase in minute ventilation is perceived by the pregnant woman as shortness of breath, which affects 60–70 per cent of women. This physiological dyspnoea is usually mild and affects 50 per cent of women before 20 weeks gestation, but resolves immediately postpartum.

Dehydroepiandrosterone (DHEA) is a steroid hormone synthesised from cholesterol (via Pregnenolone) by the adrenal glands. The foetus manufactures DHEA, which stimulates the placenta to form oestrogen, thus keeping a pregnancy going. Production of DHEA stops at birth, then begins again around age seven and peaks when a person is in their mid-20s

Amniotic fluid volume begins to increase rapidly in the second and third trimester as the fetal kidneys continue to develop. By 35 weeks gestation the amniotic fluid volume reaches a maximum average of about 800 ml after which it decreases slightly to term.

Intrahepatic cholestasis of pregnancy (ICP) classically presents as severe pruritus in the third trimester. Characteristic findings include the absence of primary skin lesions and elevation of serum levels of total bile acids.

The most specific and sensitive marker of ICP is total serum bile acid (BA) levels greater than 10 micromol/L. In addition to the elevation in serum BA levels, the cholic acid level is significantly increased and the chenodeoxycholic acid level is mildly increased, leading to elevation in the cholic
henodeoxycholic acid level ratio. The elevation of aminotransferases associated with ICP varies from a mild increase to a 10- to 25-fold increase.

Total bilirubin levels are also increased but usually the values are less than 5 mg/dL. Alkaline phosphatase (AP) is elevated in ICP up to 4-fold, but this is not helpful for diagnosis of the disorder since AP is elevated in pregnancy due to production by the placenta- Mild elevation of gamma glutamyl transferase (GGT) is seen with ICP but occurs in fewer than 30% of cases. However, if GGT is elevated in cases of ICP, that patient is more likely to have a genetic component of the liver disease.

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.

Patient mentioned in the given case has developed clinical features of cervical insufficiency and the possible treatment options include:
1- Cerclage, which is the technique used for the reinforcement of cervical ring with nonabsorbable suture material and is indicated based on ultrasonographic findings. It is the treatment of choice when cervical shortening is detected by ultrasonography before 22 to 24 weeks of gestation.

2- Vaginal progesterone is used to reduce the risk of preterm delivery in women who have a prior history of idiopathic preterm delivery or cervical shortening, which is confirmed in the current pregnancy also by ultrasonography.This method is applicable only to those women who do not meet the criteria for Cerclage.

All the other options of management are incorrect in the given case.

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

There is high possibility of her being pregnant. Urine B-hCG has to be checked to exclude pregnancy.

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

If the external anal sphincter is in tact then this is a 1st or 2nd degree tear. As the perineal muscles are involved this is 2nd degree tear.

Female infants are thought to be born with the total number of gametes they will posses in their lifetime. About 1 million healthy oocytes are present at birth. However, only about 300,000 of these oocytes survive to puberty, a number which continues to decline until all the oocytes are depleted triggering menopause.

Station 0 – This is when the baby’s head is even with the ischial spines. The baby is said to be engaged when the largest part of the head has entered the pelvis.
If the presenting part lies above the ischial spines, the station is reported as a negative number from -1 to -5.

Upon penetration, if all is normally occurring, the process of egg-activation occurs, and the oocyte is said to have become activated. This is thought to be induced by a specific protein phospholipase c zeta. It undergoes its secondary meiotic division, and the two haploid nuclei (paternal and maternal) fuse to form a zygote.

Pyelonephritis is the most common serious medical problem that complicates pregnancy. Infection is more common after midpregnancy, and is usually caused by bacteria ascending from the lower tract. Escheria coli is the offending bacteria in approximately 75% of cases. About 15% of women with acute pyelonephritis are bacteraemia- A common finding is thermoregulatory instability, with very high spiking fevers sometimes followed by hypothermia- Almost 95% of women will be afebrile by 72 hours. However, it is common to see continued fever spikes up until that time- Thus, further evaluation is not indicated unless clinical improvement at 48-71 hours is lacking. If this is the case, the patient should be evaluated for urinary tract obstruction, urinary calculi and an intrarenal or perinephric abscess. Ultrasonography, plain radiography, and modified intravenous pyelography are all acceptable methods, depending on the clinical setting.

In case a person tests positive for chlamydia, all sexual partners over the period of 6 months should to contacted and started on appropriate antibiotics.

This patient presenting with oligohydramnios in her third trimester and had reported an episode of sudden gush of fluid secondary to ruptured membrane which she had mistaken to be “urinary incontinence”.  Hence, the most likely cause of oligohydramnios in this patient will be premature preterm rupture of membrane (PPROM).

An amniotic fluid volume which is less than expected for gestational age is called as Oligohydramnios and is typically diagnosed by ultrasound examination. This condition can be qualitatively described as reduced amniotic fluid volume and quantitatively as amniotic fluid index ≤5 cm or a single deepest pocket <2 cm. Oligohydramnios either can be idiopathic or may have a maternal, fetal or placental cause. Fetal prognosis in this case depends on several factors like the underlying cause, the severity of loss ie. reduced versus no amniotic fluid state and the gestational age at which oligohydramnios occurred. As an adequate volume of amniotic fluid is critical for the normal fetal movements, for fetal lung development and for cushioning the fetus and umbilical cord from uterine compression, so pregnancies complicated with oligohydramnios are at higher risk for fetal deformation, pulmonary hypoplasia and umbilical cord compression.
Oligohydramnios is also associated with an increased risk for fetal or neonatal death, which can either be related to the underlying cause of reduction in amniotic fluid volume or due to the sequelae caused due to reduced amniotic fluid volume. The amniotic fluid volume reflects the balance between fluid production and movement of fluid out of the amniotic sac and the most common mechanisms behind oligohydramnios are fetal oliguria/anuria or fluid loss due to rupture of membranes; also reduction in the amount of lung fluid or increased swallowing do not play major roles in this. Idiopathic cases as in idiopathic oligohydramnios, may be due to alterations in the expression of water pores like aquaporin 1 and aquaporin 3, present in fetal membranes and placenta.

Causes of oligohydramnios
a) Maternal causes includes:
– Medical or obstetric conditions associated with uteroplacental insufficiency like preeclampsia, chronic hypertension, collagen vascular disease, nephropathy, thrombophilia.
– Intake of medications like angiotensin converting enzyme inhibitors, prostaglandin synthetase inhibitors, trastuzumab.
b) Placental causes are:
– Abruption of placenta
– Twin polyhydramnios-oligohydramnios sequence which is the Twin to twin transfusion
– Placental thrombosis or infarction
c) Fetal cases leading to oligohydramnios are:
– Chromosomal abnormalities
– Congenital abnormalities which are associated with impaired urine production
– Growth restriction
– Demise
– Post-term pregnancy
– Ruptured fetal membranes
– Infections
– Idiopathic causes

During First trimester: Etiology of oligohydramnios during the first trimester is often unclear. As the gestational sac fluid is primarily derived from the fetal surface of the placenta via transamniotic flow from the maternal compartment and secretions from the surface of the body of the embryo reduced amniotic fluid prior to 10 weeks of gestation is rare.

During Second trimester: Fetal urine begins to enter the amniotic sac and fetus begins to swallow amniotic fluid by the beginning of second trimester, therefore, during this period any disorders related to the renal/urinary system of the fetus begins to play a prominent role in the etiology of oligohydramnios. Some of such anomalies include intrinsic renal disorders like cystic renal disease and obstructive lesions of the lower urinary tract like posterior urethral valves or urethral atresia. Other common causes of oligohydramnios in the second trimester are maternal and placental factors and traumatic or nontraumatic rupture of the fetal membranes.

During Third trimester: Oligohydramnios which is first diagnosed in the third trimester is often associated with PPROM or with conditions such as preeclampsia or other maternal vascular diseases leading to uteroplacental insufficiency. Oligohydramnios frequently accompanies fetal growth restriction as a result of uteroplacental insufficiency.

Foetal movements often become apparent at about 18-20 weeks gestation. This phenomenon is also called quickening. The Foetal movements continue to increase in frequency and force until 32 weeks where they plateau. Foetal movements can be used to monitor the wellbeing of the foetus, alerting the mother and healthcare providers to a problem.

This is VIN. Smoking is a risk factor. It is also more common in immunocompromised patients.

This patient is towards the end of the first stage of labour and is having complications. Labour is divided into 3 stages. The first stage begins at regular uterine contractions and ends with complete cervical dilatation at 10 cm. It has a latent phase and an active phase- The active phase is usually considered to have begun when cervical dilatation reaches 4 cm. So this patient is in the active phase of the first stag- The second stage begins with complete cervical dilatation and ends with the delivery of the foetus. The third stage of labour is the period between the delivery of the foetus and the delivery of the placenta and fetal membranes.

This patient’s contractions seem adequate and yet the fetal heart tone with baseline 80/min and absent variability suggests fetal distress. This is category III of the fetal heart rate pattern because the baseline rate is < 110/min with absent variability. It is usually predictive of abnormal acid-base status. The recommended actions are maternal position change and oxygen administration, discontinuation of labour stimulus such as oxytocin, treatment of possible underlying conditions, and expedited delivery.
→ Magnesium sulphate infusion is mainly used to prevent eclamptic seizures and despite no evidence of its effectiveness as a tocolytic agent, it is used sometimes to reduce risks of preterm birth.
→ Fetal scalp pH monitoring would help determine if there is indeed an acidosis and should be done before deciding whether a Caesarean section is necessary, but maternal position change and oxygen administration should be done first.
→ Ultrasonography may be used for preinduction cervical length measurement or if the active stage has already started- It is considered more accurate than digital pelvic exam in the assessment of fetal descent; however, at this point maternal position change and oxygen administration should be done first.
→ Immediate Caesarean section would be done if fetal scalp pH monitoring revealed a pH < 7.20. At this point, the best next step is maternal position change and oxygen administration.

Ovulation in the menstrual cycle usually occurs over 4 days. There is an increase in basal body temperature at the time of ovulation due to the effect of progesterone.

A high Day 21 progesterone level indicates ovulation and the release of an egg.

Dysmenorrhea is described as painful menstruation. The symptoms start at the time of ovulation and persist till menstruation.

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

Trichomoniasis is considered a sexually transmitted infection found both in men and women, and is caused by the flagellate protozoan Trichomonas vaginalis. The organism is mainly found in the vagina and the urethra. Though many infected women can be asymptomatic, they can also present with yellow frothy vaginal discharge, itching and vaginitis, dysuria or an offensive odour. About 20-30% of women with the infection however are asymptomatic. For the diagnosis of t. vaginalis in women, a swab is taken from the posterior fornix during speculum examination and the flagellates are detected under light-field microscopy. The recommended treatment for t. vaginalis during pregnancy and breastfeeding is 400-500mg of metronidazole twice daily for 5 -7 days. High dose metronidazole as a 2g single dose tablet is not advised during pregnancy. All sexual partners should also be treated and screened for other STIs.

Haemoglobin decreases from 13.3 g/dL to 10.5 g/dL from the start of pregnancy i.e. First trimester till the 3rd trimester.

Molding allows the skull bones of the fetal head some mobility during the normal delivery of foetus as the skull changes its shape to accommodate passage through the mothers pelvis. However this does not occur in breach delivery where the skull is in circular shape. Babies born breech typically have craniofacial and limb deformations resulting from their in utero position. These babies characteristically have a long, narrow head, (“dolichocephaly” or “type 1”), with a prominent occipital shelf, redundant skin over the neck, overlapping lambdoidal sutures, and an indentation below their ears (from shoulder compression).

Polycystic ovary syndrome (PCOS) is a condition in which the ovaries produce an abnormal amount of androgens, male sex hormones that are usually present in women in small amounts. The name polycystic ovary syndrome describes the numerous small cysts (fluid-filled sacs) that form in the ovaries. However, some women with this disorder do not have cysts, while some women without the disorder do develop cysts.

The symptoms of PCOS may include:
– Missed periods, irregular periods, or very light periods
– Ovaries that are large or have many cysts
– Excess body hair, including the chest, stomach, and back (hirsutism)
– Weight gain, especially around the belly (abdomen)
– Acne or oily skin
– Male-pattern baldness or thinning hair
– Infertility
– Small pieces of excess skin on the neck or armpits (skin tags)
– Dark or thick skin patches on the back of the neck, in the armpits, and under the breasts

The so-called Laurence-Moon-Biedl syndrome is a fairly rare condition characterized by six cardinal signs, namely obesity, atypical retinitis pigmentosa, mental deficiency, genital dystrophy, polydactylism and familial occurrence.

Froehlich syndrome is characterized by increased or excessive eating that leads to obesity, small testes, and a delay in the onset of puberty. It is also common for children with Froehlich syndrome to experience the delay in physical growth and the development of secondary sexual characteristics.

Cushing’s syndrome is a disorder that occurs when your body makes too much of the hormone cortisol over a long period of time. Cortisol is sometimes called the “stress hormone” because it helps your body respond to stress. Cortisol also helps. maintain blood pressure. regulate blood glucose, also called blood sugar.

Pseudohypoparathyroidism is characterized by short stature, a round face, short neck, and shortened bones in the hands and feet. Intelligence usually ranges from low normal to mentally retarded. Headaches, weakness, tiring easily, lethargy, cataracts and blurred vision or hypersensitivity to light may also be present.
This patient’s condition can only be explained by PCOS.

Antepartum haemorrhage (APH) is defined as bleeding from or in to the genital tract, occurring from 24+0 weeks of pregnancy and prior to the birth of the baby.

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 changes seen in breast tissue with the menstrual cycle are accentuated during pregnancy. Deposition of fat around glandular tissue occurs, and the number of glandular ducts is increased by oestrogen, while progesterone and human placental lactogen (hPL) increase the number of gland alveoli. Prolactin is essential for the stimulation of milk secretion and during pregnancy prepares the alveoli for milk production. Although prolactin concentration increases throughout pregnancy, it does not then result in lactation since it is antagonized at an alveolar receptor level by oestrogen.

Lymph node involvement means that the carcinoma is stage 4. The 5 year survival of stage 4 endometrial carcinoma is 16%.

The contents of the broad ligament:
Fallopian tubes
Ovarian artery
Uterine artery
Ovarian ligament
Round ligament of uterus

Prostaglandin E1 and E2 help maintain the patency of the DA during pregnancy. PGE2 is by far the most potent and important. It is produced in large quantities by the placenta and the DA itself.

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.

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.

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

HPV 16 and 18 are responsible for 70% of cases of HPV related cancers. They are considered the most important high risk genotypes of HPV. As well as cervical cancer they are associated with cancers of the oropharynx and anogenital region.

There are over 100 genotypes of HPV including several other high risk HPV types. Gardasil® is a quadrivalent vaccine against HPV Types 6, 11, 16, and 18

HPV genotypes 6 and 11 are low risk and cause anogenital warts.

Typically 70% of HPV infections are cleared within 1 year and 90% are cleared within 2 years

Threatened abortion:
– Vaginal bleeding with closed cervical os during the first 20 weeks of pregnancy
– Occurs in 25% of 1st-trimester pregnancies
– 50% survival
More than half of threatened abortions will abort. The risk of spontaneous abortion, in a patient with a threatened abortion, is less if fetal cardiac activity is present.

Lymphatic vessels from the vagina drain from the parts of the vagina as follows:
• Superior part: to the internal and external iliac lymph nodes.
• Middle part: to the internal iliac lymph nodes.
• Inferior part: to the sacral and common iliac nodes.

Klinefelter syndrome is associated with testicular atrophy, eunuchoid body shape, tall, long extremities, female hair distribution and gynaecomastia. It is a common cause of hypogonadism seen during fertility workup.

The pudenal nerves has three branches, namely the inferior rectal, perineal and the dorsal nerve of the clitoris. The perineal nerve has two branches: The superficial perineal nerve gives rise to posterior scrotal or labial (cutaneous) branches, and the deep perineal nerve supplies the muscles of the deep and superficial perineal pouches, the skin of the vestibule, and the mucosa of the inferior most part of the vagina. The inferior rectal nerve communicates with the posterior scrotal or labial and perineal nerves. The dorsal nerve of the penis or clitoris is the primary sensory nerve serving the male or female organ, especially the sensitive glans at the distal end.

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

The management of low-grade squamous intraepithelial lesions (LSIL) on cervical cytology in women ages 25 years or older depends upon whether the patient underwent high-risk human papillomavirus (HPV) testing.

Women in this age group comprise two different populations in terms of cervical cancer screening strategies. Professional organizations recommend that women ages 25 to 29 years be screened with cytology alone, while women 30 years or older should be screened with cytology and HPV co-testing. Thus, the American Society for Colposcopy and Cervical Pathology (ASCCP) prefers that women ages 25 to 29 years are not managed based upon HPV results, even if an HPV test was performed at the time of screening. For women with ages 30 years or older and HPV positive, colposcopy must be performed.

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

This patient presents with secondary amenorrhea, a condition diagnosed in patients with – 3 months of absence of menstruation when they had regular menstruation previously or absence of menstruation for 9 months in a patient who had oligomenorrhea- This differs from primary amenorrhea, which is defined as absence of menstrual periods in a female by the age 16 when she has other secondary sexual characteristics or absence of menstrual periods by the age of 14 when she does not have any other secondary sexual characteristics.

In female patients of child-bearing age, the initial test in evaluating secondary amenorrhea is the pregnancy test. This test has been done in this patient and it is negative- The next step in evaluation in this patient should be serum TSH and prolactin level measurements. Thyroid disease and pituitary pathologies are some of the most common causes of secondary amenorrhea- If these tests were to be found normal, the progesterone challenge test would be the following test as this allows evaluation whether amenorrhea is due to progesterone deficiency in a patient with normal oestrogen levels.

→ Order FSH and LH level is incorrect. These studies are done if the progesterone withdrawal test is negative but the oestrogen-progesterone challenge test is positive; however, the patient should first have TSH and prolactin level measured; the progesterone withdrawal test is only done if TSH and prolactin are normal.
→ Order a progesterone withdrawal test is incorrect. As explained above, this test is ordered if TSH and prolactin levels are normal in a patient suspected to have secondary amenorrhea.
→ Order pelvic ultrasound is incorrect. This study is more important in primary amenorrhea evaluation as it can help confirm the presence or absence of a uterus. This patient who has had menstrual periods before does certainly have a uterus.
→ Order brain MRI is incorrect. Given how expensive this study is, it should not be done before prolactin levels are found to be significantly high, raising suspicion of a pituitary pathology.

There are between 250 and 400 lobules in each testis. The lobule is a structural unit of the testis with each lobule contained in one of the intervals between fibrous septa which extend between the mediastinum testis and the tunica albuginea. Each lobule contains 1 to 3 seminiferous tubules.

Gonorrhoea is a diplococcus bacteria known to infect the female genital tract. The bacteria is sexually transmitted and can cause an ascending infection in the uterus and fallopian tubes. According to the BASHH guidelines (British Association for Sexual Health and HIV), indication for therapy include confirmation of intracellular diplococci on microscopy or a confirmed positive NAAT. Treatment of gonorrhoea in pregnancy is as follows: Ceftriaxone 1g intramuscularly as a single dose with azithromycin 2g oral as a single dose. Pregnant individuals are not to be treated with quinolones or tetracyclines.

Gonorrhoea is a sexually transmitted disease that is caused by Neisseria gonorrhoea. It infects the mucous membrane of the genital tract epithelium in the endocervical and the urethral mucosa. Around 50% of the women are asymptomatic. However it presents as increase vaginal discharge, dysuria, proctitis and pelvic tenderness.

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.

Placental abnormalities such as placenta previa and placenta accreta are the most common reasons for considering hysterectomy as an inevitable treatment option in postpartum hemorrhage.

Placental villi normally invade only the superficial layers of endometrial deciduas basalis, but when the invasion is too deep into the uterine wall, the condition is termed as placenta accreta, increta or percreta depending on the depth of invasion.
– When the villi invade the deeper layers of the endometrial deciduus basalis, but not the myometrium it is called as Placenta accreta. This is the most common type of decidual invasion and accounts for approximately 75% of the cases.
– When the villi invade the myometrium, but do not reach the uterine serosa or the bladder is called Placenta increta. This type accounts for nearly 15% of cases.
– In cases were the villi invades into the uterine serosa or the bladder is it called as Placenta percreta and this happens in 5% of cases.

Prior uterine surgery is the main risk factor for placenta accreta and the best management is elective cesarean hysterectomy.
postpartum hemorrhage can also be caused by conditions like genital lacerations, uterine atony, retained products of conception and uterine inversion. In most of these above mentioned cases, hysterectomy is not required and remains as the last resort in extremely desperate situations.

NOTE– Though uterine atony is the most common cause of postpartum hemorrhage, it is often manageable medically.

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

When considering immunoglobulins in neonates. There are only a few key points you are likely to be tested on. 1. IgA is resistant to stomach acid and found in large amounts in breast milk. 2. IgG is the only Ig that can cross the placenta so is key for passive neonatal immunity 3. When the neonate starts synthesising its own Ig it is IgM that is produced first.

Oestrogen is secreted by the corpus luteum and is responsible for the proliferation of the endometrium to prepare it for the implantation of the zygote.

Afterpains may continue for 2-3 days (so none of the above). Breastfeeding may intensify pain due to stimulation of Oxytocin which causes uterine contractions

Blood in the peritoneal cavity rarely causes rigidity like that of a board (this is generally only found when chemical or purulent peritonitis is present).

When there is blood, there is usually a lot of rebound soreness and a lot of guarding.

A tubal ectopic pregnancy causes discomfort and tenderness in the lower abdomen, but it is not always localised to the side of the disease.

Shock is uncommon since the diagnosis is usually recognised before there is enough blood loss to elicit such signs.

Pelvic soreness is more prevalent than a pelvic mass that may be seen on a clinical exam.
Where a mass is visible, it could be an ectopic pregnancy, but it’s more likely to be a pregnancy surrounded by a blood clot caused by a leaking ectopic pregnancy.

Summary points of the two key testicular cell types:
1. Sertoli Cells = Secrete Inhibin. Forms blood-testis barrier. Have FSH receptors
2. Leydig Cells = Secrete testosterone. Have LH receptors

Uterine atony is the most common cause for postpartum haemorrhage and the conditions like multiple pregnancy, polyhydramnions, macrosomia, prolonged labour and multiparity are the most common risk factor for uterine atony.

Whereas less common causes for postpartum haemorrhage are laceration of genital tract, uterine rupture, uterine inversion and coagulopathy.

Raised pressure with the pelvis can cause a number of nerve entrapment syndromes. This is entrapment of the lateral cutaneous nerve of the thigh (or lateral femoral cutaneous nerve) also known as Meralgia Paraesthetica. Pregnancy is a risk factor. Shingles can effect this nerve but the rash would usually present itself within 14days.

Testing for GD should use the 2 hour 75g oral glucose tolerance test (OGTT) to test for GD in women. Testing women who have had GD in a previous pregnancy: early self monitoring of blood glucose OR a 75 g 2 hour OGTT as soon as possible after booking (whether in the first or second trimester) and a further 75 g 2hour OGTT at 24-28 weeks if the results of the first OGTT are normal. Testing women with risk factors for GD: 75g 2 hour OGTT at 24-28 weeks

Tocolytics are used to suppress contractions. The Canadian preterm labour trial which remains a very influential tocolytic trial to date concluded that tocolytics such as a beta agonist have no significant benefit on perinatal mortality or morbidity or prolong pregnancy to term however it did reduce the number of women delivering within 2 days by 40%. This 48 hour window is the only reason for the use of tocolytics.
Choice of tocolytic (NICE)
1st line: Nifedipine
2nd line: Oxytocin receptor antagonists e.g. atosiban

The oocyte (eggs, ova, ovum) is arrested at an early stage of the first meiosis (first meiotic) division as a primary oocyte (primordial follicle) within the ovary. Following puberty, during each menstrual cycle, pituitary gonadotrophin stimulates completion of meiosis 1 the day before ovulation.

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 combination oral contraceptive pill is an unequivocal contraindication for this patient (migraine with aura). Progestogen-only contraception, such as etonogestrel implant, levonorgestrel intrauterine device, and depot medroxyprogesterone, should be offered to her.
There is no need for a neurologist’s assessment or a brain MRI because her migraines are managed with sumatriptan nasal spray.

Most types of HRT increase the risk of breast cancer. But the risk is higher for those using combined HRT, which uses both oestrogen and progestogen. Vaginal oestrogens are not linked to an increased risk of breast cancer, whereas tibolone is. Taking HRT for 1 year or less only slightly increases breast cancer risk. However, the longer you take HRT the greater the risks are, and the longer they last.

Evidence is insufficient to conclude that long-term oestrogen therapy or hormone therapy use improves cardiovascular outcomes.

HRT containing oestrogen alone increases risk of endometrial cancer. However, this is not the case when using combined HRT.

Maximum levels of progesterone are detected at day 21 of 28 days in the menstrual cycle, assuming that ovulation has occurred at day 14. A value of >30nmol/l indicates an ovulatory cycle.

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.

Repetitive late decelerations can be caused by fetal hypoxia which results in constriction of the vessels to circulate blood from the peripheries to more important organs of the body like the brain and heart etc.

The female bony pelvis is larger, broader and more of a funnel shape. The inlet is larger and oval in shape and the sides of the female pelvis are wider apart.

This is a grade 1 prolapse

Fetal hypoxia may cause absent, increased or decreased variability. Other causes of decreased variability include: normal fetal sleep-wake pattern, prematurity and following maternal administration of certain drugs including opioids.

Variability Range:
Normal – 5 bpm – 25bpm
Increased – >25 bpm
Decreased – <5 bpm
Absent – <2 bpm

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.

IUCD is a risk factor for PID and PID has the clinical picture already described. However, fibroids should also be excluded since they may present in the same way.

A variety of changes in the cardiovascular system occur during normal pregnancy, including increases in cardiac output, arterial compliance, extracellular fluid volume and decreases in blood pressure (BP) and total peripheral resistance.

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.

During the early fetal life, oogonia proliferate by mitosis. They enlarge to form primary oocyte before birth. No primary oocyte is form after birth. The primary oocyte is dormant is the ovarian follicles until puberty. As the follicle matures, the primary oocyte completes its first meiotic division and gives rise to secondary oocyte. During ovulation the secondary oocytes starts the second meiotic division but is only completed if a sperm penetrates it. This 1st and 2nd meiotic division is known as ootidogenesis.

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

Hepatitis B is a DNA virus. All the others are RNA viruses

The superior mesenteric vein joins the splenic vein to form the hepatic portal vein.

The half life of oxytocin is 5 mins, which is why is should be started as an infusion at a low rate.

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.
