Corpus albicans is the regressed form of the corpus leuteum. It is formed when the corpus leuteum is engulfed by macrophages and a scar or fibrous tissue is formed, called the corpus albicans.

Closure of the uterus should be performed in either single or double layers with continuous or interrupted sutures. The initial suture should be placed just lateral to the incision angle, and the closure continued to a point just lateral to the angle on the opposite side. A running stitch is often employed and this may be locked to improve haemostasis. If a second layer is used, an inverting suture or horizontal suture should overlap the myometrium. Once repaired, the incision is assessed for haemostasis and ‘figure-of-eight’
sutures can be employed to control bleeding. Peritoneal closure is unnecessary. Abdominal closure is performed in the anatomical planes with high strength, low reactivity materials, such as polyglycolic acid or polyglactin. Diamorphine is advised for intra and post op analgesia and oxytocin is advised to reduce blood loss.

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

CAH leads to virilization of the female foetus. It occurs to an enzyme deficiency (21-hydroxylase). This results in a reduced levels of corticosteroids from being circulated resulting in hyperplasia of the adrenal glands and increased progesterone production. The CYP21A gene has been implicated in causes this deficiency.

Spinnability (or Spinnbarkeit), which measures the capacity of fluids to be drawn into threads, represents an indirect measurement of the adhesive and elastic properties of mucus.

Antepartum haemorrhage is any bleeding that occurs from the female genital tract during the antenatal period after the 24+0 week of pregnancy and prior to the birth of the baby. The most common causes are placenta previa and placental abruption.

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.

Incontinence in women is typically related to dysfunction of the bladder or pelvic floor muscles, with such dysfunction often arising during pregnancy or childbirth, or at the time of menopause.

A pregnant woman may experience an increase in the size of the kidneys and ureter due to the increased blood volume and vasculature.
Later in pregnancy, the woman might develop physiological hydronephrosis and hydroureteronephrosis, which are normal.
There is an increase in glomerular filtration rate associated with an increase in creatinine clearance, protein, albumin excretion, and urinary glucose excretion.
There is also an increase in sodium retention from the renal tube so oedema and water retention is a common sign in pregnant women

The uterus needs support in order to remain centered inside the pelvic cavity. The support it receives comes in two forms: dynamic and passive. The ligaments of the uterus have an important role in both.

Dynamic support is provided by the pelvic diaphragm through tonic contractions while standing and sitting and active contractions during moments of increased abdominal pressure, such as coughing or sneezing. During these moments, the ligaments of the uterus transmit the force of the diaphragm towards the organ itself, maintaining its position.

The ligaments are also crucial in providing passive support. By minimizing movement of the body and the cervix, they maintain the uterus in the typical anteverted and anteflexed position directly on top of the bladder. This provides a support for the uterus when the abdominal pressure increases.

Hence, even though the broad ligament, round ligament and ovarian ligament have some role in the suspension of the uterus, the uterosacral ligament plays the most significant role. It is also the ligament used for surgical suspension of POP.

Normal closure of the ductus arteriosus (DA) is brought about by a number of mechanisms. Upon delivery the new born babies first breath inflates the lungs and this causes a rise in pO2. Oxygen is known to cause constriction of the DA in vivo and in vitro. In addition the decreased vascular resistance means the pressure within the lumen of the DA drops aiding closure. In addition on inflation of the lungs, the lungs produce bradykinin which stimulates smooth muscle constriction of the ductus. The most important factor is thought to be the drop in Prostaglandin E2. Prostaglandin E2 maintains patency of the Ductus in the unborn child but after birth is metabolised in the lungs and its levels fall rapidly within 3 hours of birth.

SPIKES protocol for delivering serious news to patients includes:
– Set the stage includes arranging for a private, comfortable setting space, introduce patient/family & team members, maintain eye contact & sit at the same level and schedule appropriate time interval & minimize space for interruptions.
– Perception: Use open-ended questions to assess the patient’s/family’s perception of the medical situation.
– Invitation: should ask patient/family how much information they would like to know and remain cognizant of their cultural, educational & religious issues.
– Knowledge:
Warn the patient/family that serious news is coming, Speak in simple & straightforward terms, stop & check whether they are understanding.
– Empathy: Express understanding & give support when responding to emotions
– Summary & strategy: Summarize & create follow-through plan, including end-of-life discussions if applicable.

The ultrasound findings of severe growth restriction, bilateral choroid plexus cysts, clenched fists, and a large ventricular septal defect are consistent with trisomy 18, the second most common autosomal trisomy, which results in fetal loss or neonatal death in the majority of cases.  In this case, the physician is to deliver a very serious news to the patient who is presenting for a routine visit, believing her pregnancy was normal.  When serious news is unexpected, it is especially important to prepare the patient and determine how the patient would like to receive the results.
The physician is supposed to provide a comfortable setting and must ask patient’s permission to share the results. This allows the patient to respond with her preference and avoids making assumptions about whom, if anyone, she would like to be present with.  For example, some patients may prefer to defer discussion of the results until a major support person (eg, husband, mother) is present. In addition to establish patient’s preferred setting, physician should determine how much information the patient would like to receive. Some patients will prefer a detailed medical information about diagnosis and prognosis, whereas others may prefer to have time to process the news emotionally and receive further information later.  The SPIKES protocol (Setting the stage, Perception, Invitation, Knowledge, Empathy, and Summary/strategy) is a six-step model that can guide physicians in delivering serious news to patients.

These statements do not allow the patient to choose how she receives the results and assume that she does not want her mother present.

This statement fails to prepare the patient for serious news and prematurely jumps to sharing results using technical, medical terminology that may be difficult for the patient to comprehend. This approach could also be upsetting to a patient undergoing a routine ultrasound who is not expecting anything abnormal.

This statement inappropriately determines when and with whom the patient should receive the results. Instead the patient should be asked how she prefers to receive the results.

While delivering unexpected, serious news, physicians should prepare the patient and determine how the patient prefers to receive the information.

Chlamydia trachomatis (D-K subtypes) is the most common cause in this age group and fits the descriptors given.

With the help of molding, the fetal head changes its shape as the skull bones overlap. This helps in smooth delivery of the foetus through the birth canal.

Human Papillomavirus has been is implicated in the development of genital warts as well as, head and neck, anogenital and cervical cancers, with the most important high-risk strains being 16 and 18. Over 50% of women worldwide are thought to possess antibodies against various strains of HPV after natural infection. Many infections are asymptomatic and are cleared within 2 years. Several vaccines have been formulated against HPV, one of which is Gardasil, a quadrivalent vaccine against HPV types 6,11, 16,18.

Condition where there is insufficient fetal descent after pushing for ≥3 hours in nulliparous and ≥2 hours if multiparous women is defined as Second stage arrest of labor. Common risk factors for this presentation are maternal obesity, excessive weight gain during pregnancy and diabetes mellitus. Cephalopelvic disproportion, malposition, inadequate contractions and maternal exhaustion are the common etiologies of Second stage arrest of labor. Management includes Operative vaginal delivery or cesarean delivery as indicated in the case.

The second stage of labor begins with the dilatation of cervix to 10 cm and will end with fetal delivery. Parity and use of neuraxial anesthesia are the two factors which will affect the duration of second stage of labor and fetal station, which measures the descent of the fetal head through the pelvis determines its progression.

When there is no fetal descent after pushing for ≥3 hours or ≥2 hours in in nulliparous and multiparous patients respectively the condition is called an arrested second stage of labor. As her first delivery was a cesarean session due to breech presentation, this patient in the case is considered as nulliparous.

Most common cause of a protracted or arrested second stage is fetal malposition, which is the relation between the fetal presenting part to the maternal pelvis. Occiput anterior is the optimal fetal position as it facilitates the cardinal movements of labor, any deviations from this position like in occiput transverse position, can lead to cephalopelvic disproportion resulting in second stage arrest.
Inadequate contractions, that is less than 200 MVU averaged over 10 minutes, can lead to labor arrest but contractions are adequate in case of the patient mentioned.
Second stage arrest can be due to maternal obesity and excessive weight gain during pregnancy but this patient had a normal pre-pregnancy BMI of 20 kg/m2 and an appropriate weight gain of 15.9 kg 35 lb. So this also cannot be the reason.

Maternal expulsive efforts will change the fetal skull shape. This process called as molding helps to facilitate delivery by changing the fetal head into the shape of the pelvis. Whereas prolonged pressure on head can result in scalp edema which is called as caput, presence of both molding and caput suggest cephalopelvic disproportion, but is not suggestive of poor maternal effort.

Patients with a prior history of uterine myomectomy or cesarean delivery are at higher risk for uterine rupture.  In cases of uterine rupture, the patient will present with fetal heart rate abnormalities, sudden loss of fetal station (eg, going from +1 to −3 station) along with fetal retreat upward and into the abdominal cavity through the uterine scar due to decreased intrauterine pressure. In the given case patient’s fetal heart rate tracing is category 1 and fetal station has remained 0 which are non suggestive of uterine rupture.

When there is insufficient fetal descent after pushing ≥3 hours in nulliparous patients or ≥2 hours in multiparous patients is considered as second stage arrest of labor. The most common cause of second stage arrest is cephalopelvic disproportion, were the fetus presents in a nonocciput anterior position called as fetal malposition.

Shoulder dystocia is a complication associated with fetal macrosomia and may result in neurological dysfunction. Fetal macrosomia is generally defined as birth weight – 4,000 g. It occurs in about 10% of pregnancies and one of the most important predictors of fetal macrosomia is previous macrosomic infant(s). The recurrence rate of fetal macrosomia is above 30%. Other risk factors are maternal diabetes, multiparity, prolonged gestation, maternal obesity, excessive weight gain, male foetus, and parental stature- Not all cases of fetal macrosomia lead to shoulder dystocia and the occurrence of this complication is only 0.5%-1% of all pregnancies.

To make clinical decision regarding management of the patient, it is important to understand that there are other factors that lead to shoulder dystocia, such as the mother’s anatomy. While statistics suggest that there’s a tendency to choose elective Caesarean delivery for suspected macrosomia, it is believed that most of procedures are unnecessary, as evidence has shown the number of complications are not reduce- Also while it is logical to consider induction of labour at the 37th week of pregnancy, it is associated with increased Caesarean deliveries because of failed inductions. The recommended course of action is watchful waiting till the patient goes in labour.

→ Induce labour at the 37th week of gestation is not the best course of action, as it is associated with high failure rate, which often leads to Caesarean delivery.
→ Schedule elective Caesarean delivery is considered unnecessary in patients who do not have diabetes. Statistics have shown no evidence that Caesarean delivery reduces the rate of complications.
→ Serial ultrasound for fetal weight estimation is incorrect. The strategies used to predict fetal macrosomia are risk factors, Leopold’s manoeuvres, and ultrasonography. Even when they are combined, they are considered inaccurate; much less ultrasonography alone.
→ At this point, blood glucose control in pregnancies associated with diabetes seems to have desired results in preventing macrosomia- A weight loss program is usually not recommended- Instead, expectant management should be considered.

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

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

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

The Rotterdam criteria for the diagnosis of PCOS is based on a score of two out of the three criteria:
1) Oligo or anovulation
2) Hyperandrogenism – clinical (hirsutism or less commonly male pattern alopecia) or biochemical (raised FAI or free testosterone)
3) on ultrasound – contain 12 or more follicles measuring 2 to 9 mm in diameter and/or have an increased volume of 10 cm3 or greater.

The levels of evidence range from I-IV:
1a: Systematic reviews (with homogeneity) or metanalysis of randomized controlled trials: highest level of evidence.
1b: Individual randomized controlled trial (with narrow confidence interval)
1c: All or none randomized controlled trials
2a: Systematic reviews (with homogeneity) of cohort studies
2b: Individual cohort study or low quality randomized controlled trials (e.g. <80% follow-up)
2c: Outcomes Research; ecological studies
3a: Systematic review (with homogeneity) of case-control studies
3b: Individual case-control study
4: Case series (and poor quality cohort and case-control studies)
5: Expert opinion without explicit critical appraisal, or based on physiology, bench research or first principles.

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.

The condition should be an X-linked recessive condition, as it affects only male offspring. Duchene muscular dystrophy is an X-linked recessive condition. Cystic fibrosis is an autosomal recessive disorder. Spina bifida is a multifactorial condition. Down syndrome is caused by trisomy of chromosome 21. Spinal muscular atrophies are inherited in an autosomal-recessive pattern.

It is important to be aware of which ant-epileptics induce cytochrome P450. Of the above Topiramate and Phenytoin are moderate and strong inducers respectively.

Women with Beta-Thalassaemia require significant extra input during pregnancy. Folic acid 5 mg daily should be commenced 3 months prior to conception in these patients. NOTE Women with thalassaemia who have undergone splenectomy OR have a platelet count >600 should continue or be commenced on Aspirin (75 mg/day)

Pelvic organ prolapse is a common condition amongst ageing women where a weakness in the pelvic support structures of the pelvic floor allows pelvic viscera to descend.
The Pelvic Organ Prolapse Quantification system (POP-Q) is useful for describing and staging the severity of the pelvic organ prolapse.
Grade 1: the most distal portion of the prolapse is more than 1 cm above the level of the hymen
Grade 2: the most distal portion of the prolapse is 1 cm or less proximal or distal to the hymenal plane
Grade 3: the most distal portion of the prolapse protrudes more than 1 cm below the hymen but protrudes no farther than 2 cm less than the total vaginal length (for example, not all of the vagina has prolapsed)
Grade 4: vaginal eversion complete

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

PKD can follow either Autosomal dominant or recessive inheritance. Autosomal dominant is however the most common inheritance pattern and is seen in adult PKD. Infantile PKD is recessive

An LSIL Pap test shows mild cellular changes. The risk of a high-grade cervical precancer or cancer after an LSIL Pap test is as high as 19 percent.

As with an ASC-US Pap test, an LSIL Pap test is evaluated differently depending upon age. For women ages 25 or older, follow-up depends upon the results of human papillomavirus (HPV) testing:

– Women who test positive for HPV or who have not been tested for HPV should have colposcopy.
– Women who test negative for HPV can be followed up with a Pap test and HPV test in one year.

All other options are not acceptable for the above mentioned reasons.

Reported cure rates for an episode of acute BV vary but have been estimated to be between 70% and 80%. Unfortunately, more than 50% of BV cases will recur at least once within the following 12 months. Because the aetiology of BV is still not entirely understood, identifying the cause of recurrent cases is challenging. Reinfection may play a role in explaining recurrent BV, but
treatment failure is a more likely contributor. There are several theories that try to explain recurrence and persistent symptoms. The existence of a biofilm in the vagina is one such theory and is the subject of ongoing research. Biofilms occur when microorganisms adhere to surfaces. G vaginalis, one of the primary organisms

BV is not a sexually transmitted infection. The antibiotic of choice to treat BV is Metronidazole. Reassurance is not acceptable as a means of treatment.

The history is typical of Intrahepatic Cholestasis of Pregnancy, also known as obstetric cholestasis and prurigo gravidarum. The features are: Intense itching typically of the hands and feet Itch gets worse at night Responds poorly to antihistamines There is no rash. The mechanism is poorly understood but tests may show deranged LFTs. It usually resolves quickly after delivery. The other diagnoses listed are possible though less likely. Scabies normally has a rash

The risks of breast and cervical cancers are increased in women who use oral contraceptives, whereas the risks of endometrial, ovarian, and colorectal cancers are reduced.

Women who have used oral contraceptives for 5 or more years have a higher risk of cervical cancer than women who have never used oral contraceptives. The longer a woman uses oral contraceptives, the greater the increase in her risk of cervical cancer.

One study found a 10% increased risk for less than 5 years of use, a 60% increased risk with 5–9 years of use, and a doubling of the risk with 10 or more years of use. However, the risk of cervical cancer has been found to decline over time after women stop using oral contraceptives.

This patient experiences a stress based mixed urinary incontinence presented as leakage of urine while sneezing or coughing and urgency which is an intense urge to urinate with small voiding volume as her symptoms. Urinary incontinence is common and may cause significant distress in some, as seen in this patient who wears a pad every day.  Initial evaluation of mixed incontinence includes maintaining a voiding diary, which helps to classify the predominant type of urinary incontinence and thereby to determine an optimal treatment by tracking the fluid intake, urine output and leaking episodes.

All patients with mixed incontinence generally require bladder training along with lifestyle changes like weight loss, smoking cessation, decreased alcohol and caffeine intake and practicing pelvic floor muscle exercises like Kegels. Depending on the predominant type, patients who have limited or incomplete symptom relief with bladder training may benefit from pharmacotherapy or surgery.

In patients with urgency-predominant incontinence, timed voiding practice like urinating on a fixed schedule rather than based on a sense of urgency along with oral antimuscarinics are found to be useful.

Surgery with a mid-urethral sling is performed in patients with stress-predominant incontinence which is due to a weakened pelvic floor muscles as in cystocele.

In patients with a suspected urethral diverticulum or vesicovaginal fistula, a cystoscopy is usually indicated but is not used in initial evaluation of urinary incontinence due to its cost and invasiveness.

Urodynamic testing involves measurement of bladder filling and emptying called as cystometry, urine flow, and pressure (eg, urethral leak point).  This testing is typically reserved for those patients with complicated urinary incontinence, who will not respond to treatment or to those who are considering surgical intervention.

Initial evaluation of mixed urinary incontinence is done by maintaining a voiding diary, which helps to classify predominant type of urinary incontinence into stress predominant or urgency predominant and thereby to determine the optimal treatment required like bladder training, surgical intervention, etc.

Hyperemesis gravidarum (HG) is a severe form of nausea and vomiting in pregnancy, associated with weight loss of more than 5% of pre-pregnancy weight, dehydration and electrolyte imbalance. HG is usually most severe during the first 12 weeks of pregnancy and is thought to be caused by high circulating levels of HCG.

There is not yet any evidence that pregnancy itself increases the sensitivity of the area postrema, or that the hormones, oestradiol, or progesterone increase vomiting. Generally, higher concentrations of dopamine stimulates receptors in the chemoreceptor trigger zone leading to nausea and vomiting. Although this has not been demonstrated as the cause of hyperemesis gravidarum.

The 1st commonly presents as cephalic. Monozygotic (MZ) twins originate when a single egg is fertilized to form one zygote, which then divides into two embryos. Although they share the same genotype they are not phenotypically identical.

Androgen insensitivity syndrome patients have 46XY chromosomes. They are males by genotype but appear as female because of insensitivity to male hormones. It is advisable to perform gonadectomy in these patients after puberty because these patients are at increased risk of developing malignancy.

Oxytocin can also stimulate after pains that occur 2-3 following delivery.

Urinary incontinence can be divided into two main aetiologies, stress incontinence, or overactive bladder. Conservative management include lifestyle interventions, controlling fluid intake, or bladder exercises. If conservative management is no longer efficient, then medications may be indicated. Oxybutynin is an anticholinergic drug used in the treatment of urinary incontinence. As with other anticholinergic drugs, side effects include dry mouth, dry eyes, blurry vision and constipation. About 1 in 10 patients taking Oxybutynin will experience some of these side effects.

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

It is important to be aware of the difference between management of simple hypertension and pre-eclampsia in pregnancy. A BP of 140/90 to 149/99 mmHg is classed as mild hypertension. Without proteinuria this can be monitored once weekly and the patient can be discharged. If proteinuria is present with any degree of hypertension the patient requires admission and BP should be monitored at least 4 times daily according to NICE guidance.

The ischial spines and palpable through the vagina and are used as landmarks to assess the decent of the fetal head from the cervix. It also serves as a landmark for giving the pudendal block.

Patient’s symptoms and signs are suggestive of round ligament strain, which is a normal finding during pregnancy, especially in the 2nd trimester, and it does not require any medical intervention.

Round ligament is a rope-like fibromuscular band which extends from the anterolateral aspect of uterus anteriorly between the layers of the broad ligament, and passing through the deep inguinal ring into the inguinal canal.
A sharp, sudden spasm in the right iliac fossa which lasts for a few seconds which is usually triggered by sneezing, coughing, laughing and rolling over in bed are the common presentations of a round ligament pain.

Ectopic pregnancy and rupture of ectopic pregnancy are two unlikely diagnosis in this patient as she is in the second trimester of her pregnancy, whereas both the mentioned conditions occur during the first trimester.

Although appendicitis presents with pain in right iliac fossa, the pain is not causes by coughing or sneezing. Also, there will be other symptoms like tenderness and rebound tenderness in right iliac fossa in case of appendicitis.

During the first 12 weeks of pregnancy, cardiac output increases by about 30-50%. To maintain this increase, systemic vascular resistance decreases by 20-30%, while stroke volume and the heart rate increase by 25-30% and 15 beats per minute respectively.

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

Calcium phosphate salts are the most abundant form of calcium in the body, making up 99%. The majority of these salts are stored in the skeleton in different forms, mostly, hydroxyapatite, a lattice-like crystal composed of calcium, phosphates and hydroxide. The remaining calcium can be found in the extracellular fluid, tissues and skeletal muscle.

Bicornuate uterus is associated with an increased chance of urinary tract anomalies. Urinary tract anomalies were present in about 23.6% of cases of bicornuate uterus patients.

Despite the fact that pregnancy at her age is uncommon, the best advise you can give her is to take a pregnancy test.

If the test results show she is not pregnant, she can next decide whether to restart the oral contraceptive pill (0CP) or simply weep until the post-pill amenorrhoea goes away.

Although an increased follicle-stimulating hormone (FSH) level may indicate ovarian failure, it does not guarantee that no more periods will occur and does not rule out the possibility of a future pregnancy.

Obviously, she should be recommended to use a contraceptive method like condoms until the cause of her amenorrhoea is determined.
Other hormonal tests, such as luteinizing hormone and prolactin testing, may be required.

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

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

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

Randomized control trials are the gold standard when it comes to assessing the treatment options or interventions in medicine. Since its introduction, RCT has questioned the validity of treatments such as oral hypoglycaemic agents, myocardial infarction hospitalization, varicose veins, toxicity and applicability of many preventive and therapeutic procedures. The basic steps include drawing up the protocol, selecting a study population, randomization, intervention, follow up and assessment of the outcome. Note if assessing prognosis or diagnostic tests Cohort and Cross Sectional Analysis are best.

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