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

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 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.

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.

Incidental thrombocytopenia of pregnancy is the most common cause of thrombocytopenia in an otherwise uncomplicated pregnancy. The platelet count finding in this case is of little concern unless it falls below 50×109/L.

Immune thrombocytopenia is a less common cause of thrombocytopenia in pregnancy. The anti-platelet antibodies cam cross the placenta and pose a problem both to the mother and the foetus. Profound thrombocytopenia in the baby is a common finding of this condition.

Thrombocytopenia can occur in patients with severe pre-eclampsia. However, it is usually seen concurrent with other signs of severe disease.

Maternal antibodies that target the baby’s platelets can rarely cause thrombocytopenia in the mother. Instead, it can lead to severe coagulation and bleeding complications in the baby as a result of profound thrombocytopenia.

Systemic lupus erythematosus is unlikely to explain the thrombocytopenia in this patient.

During pelvimetry, the shape of the pubic arch is usually examined. It helps in determining the outcome of the type of fetal delivery.

Vulvar Intraepithelial Neoplasia (VIN) is a non-invasive squamous type lesion that carries a 15% chance of developing into squamous cell carcinoma of the vulva. Human Papillomavirus (HPV) infection, or chronic inflammatory conditions such as lichen sclerosis and lichen planus, can cause changes in the basal cells of the vulvar epithelium. Other risk factors of VIN include multiple sexual partners, cigarette smoking, and immunocompromised states. Diagnosis is by clinical examination and a biopsy confirms neoplasia.

Tocolysis is an obstetrical procedure to prolong gestation in patients, some of which are experiencing preterm labour. This is achieved through various medications that work to inhibit contractions of uterine smooth muscle.

There is no definitive first-line tocolytic agent by the American College of Obstetrics and Gynecology (ACOG) but nifedipine is most commonly used. However, in severe aortic stenosis, nifedipine can cause ventricular collapse and dysfunction.

The therapeutic target in the treatment of preterm labour is currently the pharmacological inhibition of uterine contractions with the use of various tocolytic agents. Tocolytic agents are used to maintain pregnancy for 24–48 hours to allow corticosteroids administration to act and to permit the transfer of the mother to a centre with a neonatal intensive care unit.

Oxytocin inhibitors work by competitively acting at the oxytocin receptor site. Oxytocin acts to increase the intracellular levels of inositol triphosphate. The medications currently in this class are atosiban and retosiban. Maternal nor fetal side effects have not been described for this tocolytic.

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.

The treatment of Chlamydia includes avoidance of intercourse, use of condoms and antibiotic treatment. Erythromycin 500mg orally QID for 7 days or Amoxicillin 500mg TDS for 7 days or Ofloxacin 200mg orally BD for 7 days.

This woman has experienced a septic abortion. Therefore the first step is commencement of intensive antibiotic treatment as soon as cervical swabs have been taken.

The next step is evacuation of the uterus. Curettage can be performed after a few hours, to extract any remaining infected products of conception from the uterine cavity.

The choice of antibiotics depends on the most likely microorganism involved. Therefore, prior to commencing any other procedure, it is vital to take cervical swabs for microscopic examination to guide further antibiotic therapy (correct answer).

If curettage is performed immediately there is a risk that the infection would spread.

However, if Clostridium welchii infection is suspected from the cervical smear (particularly if encapsulation of the microorganisms is present), then curettage should be performed immediately along with commencing antibiotic treatment.

Curettage can be delayed for up to 12-24 hours if other microorganisms are suspected; unless a significant increase in bleeding occurs.

Ergometrine is not essential as an immediate treatment measure as the patient is not bleeding heavily and reports that her bleeding has decreased. However, ergometrine is commonly given when curettage is performed.

Premenstrual dysphoric disorder (PMDD) is a more serious form of premenstrual syndrome (PMS). PMS causes bloating, headaches, and breast tenderness a week or two before your period.

With PMDD, you might have PMS symptoms along with extreme irritability, anxiety, or depression. These symptoms improve within a few days after your period starts, but they can be severe enough to interfere with your life.

PMDD symptoms appear a week or two before menstruation and go away within a few days after your period starts. In addition to PMS symptoms, you may have:

Anger or irritability.
Anxiety and panic attacks.
Depression and suicidal thoughts.
Difficulty concentrating.
Fatigue and low energy.
Food cravings or binge eating.
Headaches.
Insomnia.
Mood swings.

The following treatments have been shown to relieve symptoms:

Sertraline, escitalopram, paroxetine, and fluoxetine are SSRIs (selective serotonin reuptake inhibitors). SSRIs are the first-line treatment and are extremely effective.
The second line of defence is alprazolam (a short course recommended due to its addictive potential).
The use of temazepam has little advantage because it only aids with sleep and is relatively short-acting.
Lifestyle modifications-weight loss, exercise, quitting smoking, and relaxation therapies for less severe PMS.
Danazol-suppresses the ovulation and helps with mastalgias associated with PMS.

During the first 8 weeks of pregnancy, concentrations of hCG in the blood and urine usually double every 24 hours. Levels of the hormone typically peak at around 10 weeks, decline until 16 weeks, then remain constant.

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

The ureters receive innervation by a number of nerve plexuses. The nerves supplying the ureters originate from spinal segments T11 to L2. When you think about ureteric colic giving classic ‘loin to groin’ pain it is because the pain is referred to these dermatomes.

Bicarbonate serves as the main buffer in the blood. Other than this phosphate, ammonia and haemoglobin also act as buffers to some extent.

Antiepileptic, phenytoin more so than topiramate are inducers of cytochrome P450. They should not be given with COCPs. The metabolism of oestrogen and progestogen is increased by anti-epileptic drugs that induce cytochrome P450 leading to a loss of contraceptive effect.

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.

Circulation in the foetus: 1. Deoxygenated fetal blood is conducted to the placenta via the two umbilical arteries. The umbilical arteries arise from the internal iliac arteries.
2. Gas exchange occurs in placenta.
3. Oxygenated blood from the placenta passes through the single umbilical vein and enters the inferior vena cava (IVC).
4. About 50% of the blood in the IVC passes through the liver and the rest bypasses the liver via the ductus venosus. The IVC also drains blood returning from the lower trunk and extremities.
5. On reaching the heart, blood is effectively divided into two streams by the edge of the interatrial septum (crista dividens) (1) a larger stream is shunted to the left atrium through the foramen ovale (lying between IVC and left atrium) (2) the other stream passes into right atrium where it is joined by blood from SVC which is blood returning from the myocardium and upper parts of body. This stream therefore has a lower partial pressure of oxygen.
6. Because of the large pulmonary vascular resistance and the presence of the ductus arteriosus most of the right ventricular output passes into the aorta at a point distal to the origin of the arteries to the head and upper extremities. The diameter of the ductus arteriosus is similar to the descending aorta. The patency of the ductus arteriosus is maintained by the low oxygen tension and the vasodilating effects of prostaglandin E2;
7. Blood flowing through the foramen ovale and into left atrium passes into the left ventricle where it is ejected into the ascending aorta. This relatively oxygen rich blood passes predominantly to the head and upper extremities.

Women aged 25-49 years living in England are routinely recalled for screening every three years. Women receive their first invitation for cervical screening at 25 years of age. They are not invited earlier as changes in the young cervix can be normal and result in unnecessary treatment. Provided the smears remain negative and there are no symptoms to suggest cervical cancer, the routine recall is three years for women aged 25-49 years. Women aged 50-64 years old are routinely recalled for a smear every five years. After the age of 65 years, women are only screened if they have not had a smear since the age of 50 years (including those who have never had a smear) or those who have had recent abnormal smears. This is because due to the natural history and progression of cervical cancer, it is highly unlikely that women over 65 years old will go on to develop the disease. 

Fertilization usually occurs in the fallopian tubes after ovulation. The zygote moves through the fallopian tube and implants in the endometrium about 7-9 days after fertilisation, or 6-12 days after ovulation.

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.

In premenopausal women, watchful waiting usually involves monitoring for symptoms (pelvic pain or pressure) and repeating the pelvic ultrasound after six to eight weeks. If the ovarian cyst does not enlarge or if it resolves during the period of watchful waiting, it does not usually require surgical removal. Some premenopausal women will be advised to take a birth control pill during this time to help prevent new ovarian cysts from developing.

If a cyst decreases in size or does not change, the ultrasound is often repeated at regular intervals until your healthcare provider is certain that the cyst is not growing. If the cyst resolves, no further testing or follow-up is required.
Surgery may be recommended in the following situations:
– A cyst is causing persistent pain or pressure, or may rupture or twist.
– A cyst appears on ultrasound to be caused by endometriosis and is removed for fertility reasons.
– Large cysts (>5 to 10 cm) are more likely to require surgical removal compared to smaller cysts. However, a large size does not predict whether a cyst is cancerous.
– If the cyst appears suspicious for cancer. If you have risk factors for ovarian cancer or the cyst looks potentially cancerous on imaging studies, your healthcare provider may recommend surgery.
– If the suspicion for ovarian cancer is low but the cyst does not resolve after several ultrasounds, you may choose to have it removed after a discussion with your healthcare provider. However, surgical removal is not usually necessary in this case.

The 3rd arch gives rise to the Glossopharyngeal nerve.

The vaginal artery is the homolog to the inferior vesical artery in males. In most of the cases it arises from the internal iliac artery.

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.

IgM rise is typically seen with acute infection. IgG is produced in response to infection but is produced later than IgM. IgG is also produced in response to vaccination. If IgG and IgM are negative the patient is susceptible to Rubella infection. If IgG +ve and IgM -ve the patient should be considered immune. If IgM +ve this suggests acute infection or false positive IgM (not uncommon)

After the release of the oocyte, the theca and the granulosa cells form the corpus luteum which undergoes extensive vascularization for continued steroidogenesis. Progesterone is secreted by the luteal cells and is synthesized from cholesterol.

The period from attaining a complete cervical dilation of 10 cm to fetal delivery is considered as the second stage of labor. In the given case patient have achieved an excellent fetal descent to +3 due to her average-sized infant of 3.4 kg, suitable pelvis (no fetal molding or caput, suggesting no resistance against the bony maternal pelvis), and a favorable fetal position of left occiput anterior. 
But with no further fetal descent the patient fulfills the following criterias suggestive of second-stage arrest like:
≥3 hours of pushing in a primigravida without an epidural or ≥4 hours pushing with an epidural, as in this patient
OR
≥2 hours of pushing in a multigravida without an epidural or ≥3 hours pushing with an epidural.

As continued pushing without any effect will lead to complications like postpartum hemorrhage, limiting the chances of spontaneous vaginal delivery, it is better to manage this case by operative vaginal delivery procedures like vacuum-assisted delivery, to expedite delivery. maternal exhaustion, fetal distress, and maternal conditions like hypertrophic cardiomyopathy, in which the Valsalva maneuver is not recommended are the other indications for performing an operative vaginal delivery.

Fundal pressure is the technique were external pressure is applied to the most cephalad portion of the uterus, were the applied force is directed toward the maternal pelvis. The maneuver was not found to be useful in improving the rate of spontaneous vaginal deliveries.

Epidurals will not arrest or affect spontaneous vaginal delivery rates, instead they just lengthen the second stage of labor. Also an appropriate analgesia is a prerequisite to use in operative vaginal delivery.

Manual rotation of an infant to a breech presentation for breech vaginal delivery is called as internal podalic version. It is contraindicated in singleton deliveries due to the high risk associated with breech vaginal delivery in regards to neonatal mortality and morbidity.

The ideal fetal head position in vaginal delivery is occiput anterior (OA) as the flexed head in this provides a smaller diameter and facilitates the cardinal movements of labor. The occiput posterior (OP) position, in contrast to OA, presents with a larger-diameter head due to the deflexed position. So the chance for spontaneous vaginal delivery will be decreased if fetal head is rotated to OP position.

A lack of fetal descent after ≥4 hours of pushing in a primigravida with an epidural (≥3 hours without) or ≥3 hours in a multigravida with an epidural (≥2 hours without) is defined as second stage arrest of labor.  The condition is effectively managed with operative vaginal delivery procedures like vacuum-assisted delivery. Other common indications for operative vaginal delivery are maternal exhaustion, fetal distress, and maternal conditions where the Valsalva maneuver is not recommended.

The history of acutely painful defecation associated with spotting of bright blood is very suggestive of an acute anal fissure. Typically, the patient reports severe pain during a bowel movement, with the pain lasting several minutes to hours afterward. The pain recurs with every bowel movement, and the patient commonly becomes afraid or unwilling to have a bowel movement, leading to a cycle of worsening constipation, harder stools, and more anal pain. Approximately 70% of patients note bright-red blood on the toilet paper or stool. Occasionally, a few drops may fall in the toilet bowl, but significant bleeding does not usually occur with an anal fissure.. After gently spreading the buttocks, a close check of the anal verge can typically confirm the diagnosis.
Rectal inspection is excruciatingly painful and opposed by sphincter spasm; however, if the fissure can be seen, it is not necessary to make the diagnosis at first.

A perianal abscess, which presents as a sore indurated area lateral to the anus, or local trauma linked with anal intercourse or a foreign body, are two more painful anorectal disorders to rule out.

Anal fistulae do not appear in this way, but rather with perianal discharge, and the diagnosis is based on determining the external orifice of the fistula.

Although first-degree haemorrhoids bleed, they do not cause defecation to be unpleasant.

Although carcinoma of the anus or rectum can cause painful defecation, it would be exceptional in this situation.
