The urinary bladder is composed of the transitional epithelium, followed by the lamina propria made up of the fibroelastic connective tissue. The muscularis layer covers the lamina propria which is made up of three poorly defined layers of smooth muscles; the inner longitudinal, middle circular and the outer longitudinal layer. The bladder is covered on the superior surface and the lateral surface by the peritoneum.

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

Glomerular filtration rate (GFR) rises immediately after conception and increases by about 50 per cent overall, reaching its maximum at the end of the first trimester. GFR then falls by about 20 per cent in the third trimester, returning to pre-pregnancy levels within 12 weeks of delivery.

The normal range for a term baby is pH: 7.18 – 7.38, and preterm pH: 7.14 – 7.4. A pH below 7.1 therefore indicates acidosis.

Tamoxifen is a SERM that is effective in treating hormone-responsive breast cancer, it acts as an antagonist to prevent receptor activation by endogenous oestrogen. As agonist of the endometrial receptors it promotes endometrial hyperplasia and hence increases the risk of endometrial cancer.

Squamous cell carcinoma is the most common type of vaginal cancer.

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

Major vessel injury is the most important potential complication when undertaking laparoscopy. It’s incidence is 0.2/1000. Bowel Injury is more common at 0.4/1000

Signs of shoulder dystocia:
– Difficulty with delivery of the face and chin
– The head remaining tightly applied to the vulva or even retracting (turtle-neck sign)
– Failure of restitution of the fetal head
– Failure of the shoulders to descend
Upon identifying shoulder dystocia additional help should be called and McRoberts manoeuvre (flexion and abduction of the maternal hips, positioning the maternal thighs on her abdomen) should be performed first. Fundal pressure is associated with uterine rupture and should not be used.

The most likely cause of her bleeding is an endometrial polyp formation due to the tamoxifen.

Tamoxifen is often prescribed to decrease risk of breast cancer recurrence in premenopausal women with oestrogen receptor-positive cancers.

As with any medication, it has known side effects, which include endometrial polyp formation, subendometrial oedema and, rarely, endometrial carcinoma.

A polyp or carcinoma can cause uterine bleeding, but a polyp is more likely to occur.

Routine endometrial thickness screening is not recommended in all women taking tamoxifen. However, in cases of abnormal bleeding, ultrasound assessment of endometrial thickness, hysteroscopy and curettage are indicated to assess the endometrium in more detail.

Tamoxifen is not associated with endometrial atrophy.

Endometrial metastasis from a breast cancer is rare, and tamoxifen would not usually induce follicular development in a woman who has had chemotherapy and resultant amenorrhoea.

Traditional POP main mode of contraceptive action: thickening of cervical mucus Desogestrel-only POP main mode of contraceptive action is inhibition of ovulation Cerazette® is the only Desogestrel-only POP in the options above. Other desogestrel brands include: Aizea® Cerelle® Nacrez® The other POPs listed are considered traditional POPs and have the following compositions: Norgeston® – Levonorgestrel 30 mcg Micronor® & Noriday® – Norethisterone 350 mcg Femulen® – Ethynediol diacetate 500 mcg

During pregnancy, the chances for a woman to develop oral candidiasis double. An aphthous ulcer has a yellowish floor which is surrounded by an erythematous halo while in lichen planus, the lesions do not have the appearance of a thick white mark but are more or less lace-like. The lesions in leucoplakia have raised edges and they appear as bright white patches which are sharply defined and cannot be rubbed out. Smoking may affect the tongue, producing tongue coating. In this case the tongue is just inflamed which is a sign of infection.

The Rhesus status of a mother is important in pregnancy and abortion. The exposure of an Rh-negative mother to Rh antigens from a positive foetus, will influence the development of anti-Rh antibodies. This may cause problems in subsequent pregnancies leading to haemolysis in the newborn. Rh Anti RhD- globulin is therefore given to non-sensitised Rh-negative mothers to prevent the formation of anti-Rh antibodies within 72 hours following abortion. Anti RhD globulin is not useful for already sensitized, or RhD positive mothers.

Yasmin has been linked to decreased fluid retention and weight gain as a side effect of COCs, which is why most women who experience this side effect prefer Yasmin®.
Due to its anti-mineralocorticoid properties, drospirenone, unlike earlier progestogens, is associated with no weight gain or even moderate weight loss.
Yasmin has a similar failure rate to other COCs. No evidence using Yasmin is linked to a lower risk of cervical cancer as a long-term side effect of COCs. Yasmin, like all COCs, can cause spotting and irregular bleeding in the first few months of use.
Drospirenone, a progesterone component, has antiandrogenic properties and is slightly more successful in treating acne, but the difference is not big enough to make it preferable in terms of acne therapy or prevention when compared to other COCs.

Diastolic murmurs occur in conditions such as mitral stenosis, tricuspid stenosis and even in carditis. They are always pathological during pregnancy. Systolic murmurs and left axis deviation may be normal during pregnancy due to an increase in the blood volume and load on the heart.

Tamoxifen is an oestrogen antagonist in breast tissue but it acts as a partial oestrogen agonist on the endometrium increasing the risk of hyperplasia and has been linked to endometrial cancer. Tamoxifen improves bone density in post-menopausal women. It is an off license treatment for gynaecomastia. Reduced lactation is a potential side effect of Tamoxifen.

Overt hypertension, developing in about 5% of Pill users, and increases in blood pressure (but within normal limits) in many more is believed to be the result of changes in the renin-angiotensin-aldosterone system, particularly a consistent and marked increase in the plasma renin substrate concentrations. The mechanisms for the hypertensive response are unclear since normal women may demonstrate marked changes in the renin system. A failure of the kidneys to fully suppress renal renin secretion could thus be an important predisposing factor.

These observations provide guidelines for the prescription of oral contraceptives. A baseline blood pressure measurement should be obtained, and blood pressure and weight should be followed at 2- or 3-month intervals during treatment. Oral contraceptive therapy should be contraindicated for individuals with a history of hypertension, renal disease, toxaemia, or fluid retention. A positive family history of hypertension, women for whom long-term therapy is indicated, and groups such as blacks, especially prone to hypertensive phenomena, are all relative contraindications for the Pill.

All other options are incorrect.

Ultrasound findings in early pregnancy can help determine the viability of an intrauterine pregnancy. In the absence of a fetal heartbeat and no visible fetal pole, the mean gestational sac diameter should be measured. A sac diameter of less than 25mm on a transvaginal ultrasound scan is likely an indication of a miscarriage. In the presence of a fetal heartbeat, the crown-rump length should be less than 7mm according to NICE guidelines. Further scans are indicated 14 days later to confirm the diagnosis. The diagnosis of ‘pregnancy of uncertain viability’ is given in situations where there is inadequate ultrasound evidence to diagnose a miscarriage, such as a developing sac but no visualisation of a foetus with a heartbeat.
Ultrasound findings for partial molar pregnancy are an enlarged placenta with multiple diffuse anechogenic patches, while findings in a complete molar pregnancy include an enlarged uterus with multiple small anechogenic spaces (snowstorm appearance), or the bunch of grapes sign representing hydropic trophoblastic villi.

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.

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

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

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

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

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

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

Maternal hypotension results from Syntocin infusion, not hypertension.

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.

Shoulder dystocia occurs when the fetal shoulder impacts on the maternal symphysis or sacrum during vaginal delivery. About 10% of babies with shoulder dystocia will suffer a brachial plexus injury, the most common one being Erb-Duchenne palsy. In Erb’s palsy, the upper nerve roots C5 and C6 are damaged due to excessive widening of the angle between the head and the shoulder. This causing temporary paralysis in the affected arm whereby the infant will present with its hand hanging limp by his side, internal rotation of the forearm, plus wrist and finger flexion. This sign is called the ‘waiter’s tip hand’. The palsy usually resolves spontaneously in a large proportion of cases.

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

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

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

Primary infertility is defined as the inability to conceive after a year of unprotected, timed sexual intercourse in a nulliparous patient under the age of 35. (After 35 years of age, infertility testing can begin after 6 months.) Because the patient’s partner’s sperm analysis is normal, female factor infertility is the most likely explanation. This patient’s adolescent hospitalizations are likely due to pelvic inflammatory disease (PID), a common cause of infertility caused by tubal scarring and blockage.

A hysterosalpingogram, which includes infusing radiocontrast into the cervix under fluoroscopy, is the first-line imaging technique for determining fallopian tube patency. A hysterosalpingogram is a non-invasive procedure that can detect uterine cavity irregularities (e.g., bicornuate uterus).

Peritoneal adhesions and endometriosis can be seen and treated directly using laparoscopy.

PID-related scarring inside the fallopian tubes can be assessed by laparoscopy with chromotubation; however, it is invasive, expensive, and not utilized first-line.

Ovulation is detected using a mid-cycle LH level. The LH surge can be detected in urine and serum 36 hours before ovulation. Regular menstrual periods are characterized by mittelschmerz (mid-cycle pelvic pain), which indicates ovulation. As a result, an LH level would be useless.

Ovarian reserve begins to deteriorate around the age of 35, and serum FSH levels rise in women who are losing their ability to ovulate. Because this patient is much younger and has regular periods, a drop in ovum quantity is unlikely to be the reason for infertility.

Increased serum androgen levels can prevent ovulation by inhibiting the release of GnRH and FSH through feedback inhibition. The patient has regular cycles and no hyperandrogenic symptoms, despite her sister having polycystic ovarian syndrome (e.g., hirsutism, irregular menses).

In a nulliparous patient under the age of 35, primary infertility is defined as the inability to conceive after a year of unprotected sexual intercourse. A hysterosalpingogram is used to determine the cause of infertility, such as tubal blockage caused by a previous pelvic infection.

Intrahepatic cholestasis characterized by reversible cholestasis typically occurring in the second or third trimester of pregnancy, elevated serum aminotransferases and bile acid level and resolution of symptoms by 2 to 3 weeks after delivery. Ursodeoxycholic acid has shown to reduce the symptoms of this condition.

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.
