Macrophages are the antigen presenting cells, they phagocytose the pathogen and after breaking them down present their protein structure to the B and T cells for a specific immune reaction to take place.

Hyaline degeneration is the most common form of fibroid degeneration. Fibroids:
Risk Factors
– Black Ethnicity
– Obesity
– Early Puberty
– Increasing age (from puberty until menopause)
Protective Factors
– Pregnancy
– Multiparity

Nausea and vomiting experienced in 80% of pregnancies Hyperemesis gravidarum (HG) is an extreme form of nausea and vomiting which affects around 1.5% of women. Caused by high levels HCG. Definitions vary but most consider it to be defined by severe nausea and vomiting associated with weight loss greater than 5% of pre-pregnancy weight with metabolic disturbance (typically dehydration and/or ketosis).

In order to maintain fetal bone growth, the maternal compartment undergoes adjustments that provide a net transfer of sufficient calcium to the foetus. Maternal compartment changes that permit calcium accumulation include increases in maternal dietary intake, increases in maternal 1, 25-dihydroxyvitamin D3 levels, and increases in parathyroid hormone (PTH) levels. The levels of total calcium and phosphorus decline in maternal serum, but ionized calcium levels remain unchanged. During pregnancy, the placenta forms a calcium pump in which a gradient of calcium and phosphorus is established which favours the foetus. Thus, circulating fetal calcium and phosphorus levels increase steadily throughout gestation. Furthermore, fetal levels of total and ionized calcium, as well as phosphorus, exceed maternal levels at term. By 10-12 weeks’ gestation, the fetal parathyroid glands secrete PTH. Fetal plasma levels of PTH are low during gestation, but increase after delivery.

An elevation in serum PRL is associated with a variety of reproductive disorders, including amenorrhea, oligomenorrhea, anovulation and/or luteal phase defects with subsequent infertility.

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.

It is less common for a girl of this age to develop fibroids, endometriosis and endometrial polyps, although these are all causes of severe dysmenorrhea. Chronic pelvic infection can be due to sexually transmitted disease but the history does not mention any previous episodes of pelvic pain or symptoms of infection such as fever. In this case, it is most likely that she has primary dysmenorrhea. Primary dysmenorrhea, in which no pathological cause can be identified, is believed to be due to the prostaglandins released by the secretory endometrium. If secondary dysmenorrhea is suspected, then endometriosis would be the most prominent cause.

While hysteroscopic and laparoscopic examinations are commonly done in adult women to rule out organic causes such as those mentioned earlier, in younger girls, they are usually only carried out if pain management with, for example, NSAIDs and the use of COCPs, have failed to either provide symptom relief or reduction.

Shortly after the morula enters the uterus, around the 4th day after fertilization, a clear cystic cavity starts forming inside the morula. The fluid passes through the zona pellucida from the uterine cavity and hence forms the blastocyst.

Only little volumes of urine are lost when her intra-abdominal pressure is elevated during coughing, laughing, jumping, and straining, which is the only symptom associated with real stress incontinence.
The other reactions are significantly more compatible with a detrusor instability diagnosis (also called urge incontinence).
If she had incontinence throughout pregnancy, it would have been stress in nature, which is what her current incontinence is.

A serious complication with a miscarriage is DIC, a severe blood clotting condition and is more likely if there is a long time until the foetus and other tissues are passed, which is often the case in missed abortion.

Levonorgestrel, also known as the morning-after pill, is a first-line oral emergency contraceptive pill with approval from the World Health Organization to prevent pregnancy. It is FDA-approved to be used within 72 hours of unprotected sexual intercourse or when a presumed contraceptive failure has occurred.

A prescription is not needed, and it is available over the counter at local pharmacies. The FDA has also approved levonorgestrel availability for all age groups due to its lack of life-threatening contraindications and side-effect profile.

There are several contraindications for the emergency contraceptive form, including allergy, hypersensitivity, severe liver disease, pregnancy, and drug-drug interactions with liver enzyme-inducing drugs. The medication is not for use in women confirmed to be pregnant; however, there is no proof nor reports of adverse effects on the mother or foetus following inadvertent exposure during pregnancy.

The risk of transplacental transmission from mother to foetus is greater in later pregnancy i.e. 26-40 weeks. Although the risk of transmission is lower in early pregnancy, if infection does occur earlier, particularly before 10 weeks, then complications are typically more severe.

Small teeth with faulty enamel is more associated with fetal alcohol syndrome (FAS).

In FAS, the most common orofacial changes are small eyelid fissures , flat facies, maxillary hypoplasia, short nose, long and hypoplastic nasal filter, and thin upper lip. The unique facial appearance of FAS patients is the result of changes in 4 areas: short palpebral fissures, flat nasal bridge with an upturned nasal tip, hypoplastic philtrum with a thin upper vermillion border, and a flat midface. Other facial anomalies include micrognathia, occasional cleft lip and/or palate and small teeth with defective enamel.

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

The CDC recommends that:
If diarrhoea occurs within 24 hours of taking oral birth control or continues for 24 to 48 hours after taking a pill, an additional dose is not needed.
If diarrhoea lasts more than 48 hours Use backup birth control, such as condoms, or avoid sexual intercourse until pills have been taken for seven diarrhoea-free days.

All other options are incorrect.

There is evidence that folic acid, iodine and vitamin D are important for reproductive outcomes. Folic acid and iodine supplementation is recommended for women planning to conceive and in pregnancy.

The recommended dose of folic acid for women without special considerations planning to conceive is 400-500 mcg. The recommended dose of folic acid for women with special considerations is 2-5 mg per day.

Women planning a pregnancy, including those with thyroid disease, should take iodine supplements in the dose of 150 mcg per day prior to and during pregnancy.

Typically fetal movements become apparent by 18-20 weeks

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

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

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.

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

The WHO defines maternal death as female death from any cause related to pregnancy or its management, including childbirth or within 42 days of termination of pregnancy. This is irrespective of the duration or site of the pregnancy.

The half-life of lidocaine is approximately 1.5 hours. It is a local anaesthetic and the maximum dose that can be given is 3mg/kg.

There is an increase risk of developing carcinoma of the uterus, if the endometrium shows hyperplasia with atypia. The standard surgery is total hysterectomy with bilateral salpingectomy which can be performed abdominally or laparoscopically If the disease is grade 1-2 and less than 1B i.e. less than 50% invasion of the uterine body.

As they respond differently to different drugs, a thorough distinguishing must be done between the two major groups of epilepsies while approaching a woman, who wishes to become pregnant while on antiepileptic drugs.

Partial epilepsies will respond to most of the antiepileptic drugs, but in case of idiopathic generalized epilepsies, especially in juvenile myoclonic epilepsy, seizure can be controlled only with a reasonably low dose of sodium valproate. Although lamotrigine may be helpful but substitution of sodium valproate with lamotrigine is not the right choice. This is because lamotrigine is not as effective as sodium valproate and will sometimes worsens myoclonic seizures in juvenile myoclonic epilepsy.

Topiramate and levetiracetam are found to be effective in idiopathic generalized epilepsy, while carbamazepine, phenytoin and gabapentin may worsen some seizure types, especially in myoclonic and absence seizures. For some women with idiopathic generalized epilepsies, there will be no effective alternative to sodium valproate as cessation of sodium valproate will lead to recurrence of the generalized seizures, especially juvenile myoclonic epilepsy. Hence, it is not advisable to discontinue the drug in auch patients.

On the other hand, sodium valproate have the highest reported teratogenicity potential among antiepileptic drugs and the Australian Pregnancy Register has reported the risk to be as high as 16% if used in first trimester. Sodium valproate should be avoided in women of reproductive age and if a patient on the medication is willing to become pregnant, she should be well informed about the risk of teratogenicity and the decision must be left to her. If she decides to accept the risks and continue with pregnancy, the lowest possible effective dose should be prescribed to her.

If the dose of sodium valproate has been reduced to minimum during pregnancy to reduce the possible teratogenesis, it is recommended to re-establish the prepartum effective dose before the onset of labor. This is because, it is the time with increased risk for seizures, especially in patients with idiopathic generalised epilepsy who are very sensitive to sleep deprivation. Valproate therapy is found to be safe during breastfeeding.

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

Group B Streptococcus (GBS) or Streptococcus agalactiae is a Gram-positive bacteria which colonizes the gastrointestinal and genitourinary tract. In the United States of America, GBS is known to be the most common infectious cause of morbidity and mortality in neonates. GBS is known to cause both early onset and late onset infections in neonates, but current interventions are only effective in the prevention of early-onset disease.

The main risk factor for early-onset GBS infection is colonization of the maternal genital tract with Group B Streptococcus during labour. GBS is a normal flora of the gastrointestinal (GI) tract, which is thought to be the main source for maternal colonization.

The principal route of neonatal early onset GBS infection is vertical transmission from colonized mothers during passage through the vagina during labour and delivery.

Intravenous penicillin G is the treatment of choice for intrapartum antibiotic prophylaxis against Group B Streptococcus.

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.

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

Occipitomental diameter is the greatest diameter of the fetal scalp and runs from chin to the prominent portion on the occiput. It measure about 12.5cm in diameter.

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

Hyperemesis gravidarum refers to intractable vomiting during pregnancy, leading to weight loss and volume depletion, resulting in ketonuria and/or ketonemia. There is no consensus on specific diagnostic criteria, but it generally refers to the severe end of the spectrum regarding nausea and vomiting in pregnancy.

Hormone changes wherein hCG levels peak during the first trimester corresponds to the typical onset of hyperemesis symptoms. It is well-known that the lower oesophageal sphincter relaxes during pregnancy due to the elevations in estrogen and progesterone. This leads to an increased incidence of gastroesophageal reflux disease (GERD) symptoms in pregnancy, and one symptom of GERD is nausea.

Hyperemesis gravidarum refers to extreme cases of nausea and vomiting during pregnancy. The criteria for diagnosis include vomiting that causes significant dehydration (as evidenced by ketonuria or electrolyte abnormalities, and the dry with coated tongue) and weight loss (the most commonly cited marker for this is the loss of at least five percent of the patient’s pre-pregnancy weight) in the setting of pregnancy without any other underlying pathological cause for vomiting.

WHO guidelines

pH: Greater than or equal to 7.2
Sperm concentration: Greater than or equal to 15 million spermatozoa per ml
Total sperm number: 39 million spermatozoa per ejaculate or more

Sperm morphology (percentage of normal forms): 4% or more

Immediately after birth the liver is deprived of the large flow of blood supplied during foetal development via the umbilical vein and portal sinus. Simultaneously the blood pressure in the portal sinus, previously as high as in the umbilical vein, falls.

The internal anal sphincter is innervated by pelvic splanchnic nerves

At the 36‑week appointment, all pregnant women should be seen again. At this appointment: measure blood pressure and test urine for proteinuria; measure and plot symphysis–fundal height; check position of baby; for women whose babies are in the breech presentation, offer external cephalic version (ECV)

Abnormal uterine bleeding is a relatively common disorder which may be due to functional disorders of the hypothalamus, pituitary, or ovary, as well as uterine lesions. However, the patient who is younger than 30 years of age will rarely be found to have a structural uterine defect. Once pregnancy, hematologic disease, and renal impairment are excluded, administration of intramuscular or oral progesterone will usually produce definitive flow and control the bleeding. No further evaluation should be necessary unless the bleeding recurs.

Endometrial aspiration, dilatation and curettage, and other diagnostic procedures are appropriate for recurrent problem or for older women. Oestrogen would only increase the problem, which is usually due to anovulation with prolonged oestrogen secretion, producing a hypertrophic endometrium.

First trimester abortions are performed using mifepristone 600 mg followed by insertion of 1 mg gemeprost vaginal pessary. The patients stays in the hospital for about 4-6 hours. At the time of abortion azithromycin 1 g and metronidazole 800 mg should be given to cover the gram positive and negative bacteria.

Multiple pregnancy is considered a high risk for obstetric complications such as spontaneous abortion, hypertensive disorders, placenta previa, and fetal malformations. Specifically, the incidence of hypertensive disorders, a common source of maternal morbidity, is 15% to 35% in twin pregnancies, which is two to five times higher than in singleton pregnancies. Additionally, the aetiology of preterm birth is not completely understood, but the association between multiple pregnancy and preterm birth is well known. A secondary analysis of the WHO Global Survey dataset indicated that 35.2% of multiple births were preterm (< 37 weeks gestation); of all multiple births, 6.1% of births were before 32 weeks gestation, 5.8% were during weeks 32 and 33, and 23.2% were during weeks 34 through 37

Nutrition in pregnancy
Weight gain must be:
– In patients <18.5 kg/m2, there should be an increase of 12.7 - 18 kg (28-40 lb)
– In patients 18.5 – 24.9 kg/m2 there should be an increase of 11.4 – 15.9 kg (25-35 lb)
– In patients 25 – 29.9 kg/m2 there should be an increase of 6.8 – 11.4 kg (15-25 lb)
– In patients ≥30 kg/m2 there should be an increase of 5 – 9 kg (11-20 lb)

Supplementation required:
– Intake of daily prenatal vitamin
– Additional specific supplements as indicated
– Avoidance of harmful substances like drugs, alcohol, etc
– Substance abuse counseling
– Avoidance of fish with high mercury levels
– Moderating caffeine intake

Food safety:
– Avoid undercooked meat, fish & eggs
– Clean raw fruits & vegetables before consuming
– Avoid unpasteurized dairy products

Nutrition in pregnancy is addressed at the initial prenatal visit based on pre-pregnancy BMI. Appropriate weight gain for a women with a normal pre-pregnancy BMI of 18.5 – 24.9 kg/m2 should be 11.4 – 15.9 kg (25-35 lb) during pregnancy. This weight gain is equivalent to the increasing caloric intake of 350 kcal/day during the second and 450 kcal/day during the third trimesters.  Patients following any specific diets like veganism can continue their usual diet throughout pregnancy as long as it contains a well-balanced quantity of protein, carbohydrates and fats.

Vitamin and mineral supplementation during pregnancy is a single, daily prenatal vitamin recommended for majority of pregnant women as it helps to fulfill most of the daily vitamin and mineral supplementation requirements. In case of patients with vitamin or mineral deficiencies like iron, calcium, etc, a specific supplementation of the deficit vitamin/mineral only is required rather than multiple prenatal vitamins to avoid consuming harmful amounts of other vitamins like vitamin A.  Vegans, who are at risk for some vitamin and mineral deficiencies like vitamin B12, calcium, iron, etc, secondary to lack of meat consumption, may require supplementation.

Pregnant women are counselled on avoidance of harmful substances like alcohol, drugs, etc and substances like fish with high mercury levels.  Although high caffeine intake during pregnancy can be harmful, a moderate intake ie, 1 or 2 cups of coffee a day is thought to be safe.

Safe handling of food is important because some food products are found to result in congenital infection and intrauterine fetal demise. Patients are also counselled to avoid undercooked meat, fish, and eggs; to thoroughly clean raw fruits and vegetables and to avoid consumption of unpasteurized dairy products.

By maintaining a proper maternal nutrition during pregnancy, patients are provide appropriate nutrition to the fetal and thereby reducing the risk of pregnancy related complications like low birth weight, preterm delivery, etc.

Pregnant patients are counseled to avoid exercises like contact sports, downhill skiing, etc which increases the risk of abdominal trauma resulting in increased risk of placental abruption. But those patients with an uncomplicated pregnancy, who are already accustomed with long-duration, high-intensity exercise like running 5 miles/day, as in the given case, can continue with their regimen if tolerated.

Proper nutrition in pregnancy includes appropriate weight gain, supplementation of vitamins and minerals, avoidance of any harmful substances, and safe handling of food. Patients with a normal pre-pregnancy BMI should gain around 11.4-15.9 kg (25-35 lb) during pregnancy by increasing their caloric intake by 350 kcal/day in the second and 450 kcal/day in the third trimesters.

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

At the time of delivery, the most important signs of complete placental separation are lengthening of the umbilical cord, per vaginal bleeding and change in shape of uterus from discoid to globular shape. The uterus contracts in size and rises upward.

Dehydroepiandrosterone is an androgen precursor produced primarily by the adrenal glands in women. The steroid hormone is produced from cholesterol at birth by the fetal adrenal glands, after which its output reduces. DHEA production picks up again from the age of 5-7 years and peaks between the ages of 20-30.

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.

Rubella infection during pregnancy may lead to miscarriage, intrauterine fetal demise, premature labour, intrauterine growth retardation, and congenital rubella syndrome. The risk of developing complications is highest if the infection is contracted within the first 12 weeks of gestation.

In those cases in which a pregnant woman has been exposed to a suspected rubella case, a specimen of blood should be tested as soon as possible for the measurement of rubella-specific IgG antibodies. If it is positive, then the woman was likely to be immune and could be reassured. If it is negative, a determination rubella-specific IgG and rubella-specific IgM antibodies should be obtained in 3 weeks to exclude an asymptomatic primary rubella infection.

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

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

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

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

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

Contracted pelvis occurs when one or more of its diameters is reduced so that it interferes with the normal mechanism of labour. A transverse diameter below 11 cm will result in difficult delivery of the foetus and C-section will be the better option in that case

Between 18-20 weeks of gestation is the best time to perform an ultrasound for the identification of any physical or anatomical abnormalities including neural tube defects.

Maternal serum screening for Down syndrome is best performed between 15-17 weeks of pregnancy and this screening includes analysis of alpha fetoprotein, estriol, and beta-HCG in maternal blood. Conducting tests on accurate dates is necessary to obtain reliable results.

Amniocentesis which is very accurate for the diagnosis of chromosomal anomalies including Down syndrome, is best performed between 16-18 weeks of gestation and it carries a risk of 1 in 200 for miscarriage. Rh negative women will need Rh D immunoglobulin (anti-D).

Chorionic villus sampling is best performed between 10-12 weeks of gestation and carries a 1 in 100 risk of miscarriage, this test is also very much accurate for diagnosis of chromosomal anomalies. Rh negative women need Rh D immunoglobulin (anti-D).

It is best to perform rubella screen before conception than during pregnancy, this is because rubella vaccine is not recommended to be given to a pregnant mother as its a live vaccine.

Despite the fact that this question includes many true-false options, the knowledge examined is particularly essential in the treatment of women who have genital herpes.
It answers many of the questions that such women have regarding the disease, how it spreads, how it may be controlled, and how it affects an unborn or recently born child.
All of these issues must be addressed in a counselling question.
Currently, the most prevalent type of genital herpes is type 1, while in the past, type 2 was more common, as confirmed by serology testing.
Type 2 illness is nearly always contracted through sexual contact, but it can go undetected for years.
Acyclovir can be taken during pregnancy, and there are particular reasons for its usage.
Neonatal herpes is most usually diagnosed when the newborn has no cutaneous lesions, and past genital herpes in the mother is protective against neonatal infection, although not always.
Where the genital infection is the initial sign of the disease rather than a relapse of earlier disease, neonatal herpes is far more frequent.
Many patients and doctors are unaware that, while the original infection might be deadly, it is usually asymptomatic.
This explains how the illness spreads between sexual partners when neither has had any previous symptoms of the disease.

Pelvic inflammatory disease (PID) is a known risk factor in causing tubal infertility due to its role in tubal damage. The tubal infertility rate after one episode of PID is thought to be about 12.5%. After two episodes the risk increases to 25%, and 50% after three episodes. The usual causative agents are chlamydia and gonorrhoea.

Mature cystic teratomas of the ovary are often discovered as incidental findings on physical examination, during radiographic studies, or during abdominal surgery performed for other indications.

Most mature cystic teratomas can be diagnosed at ultrasonography (US) but may have a variety of appearances, characterized by echogenic sebaceous material and calcification.

Follicular cysts are simple fluid-filled cysts and never have calcifications.

Mucinous cystadenoma usually develop in the third to fifth decades of life and typically cause vague symptoms, such as increasing abdominal girth, abdominal or pelvic pain, emesis, fatigue, indigestion, constipation, and urinary incontinence However, calcifications are not usually seen.

Brenner tumour is also a benign epithelial ovarian tumour but it is solid, occurring most often in women over 50 years of age.

Serous cystadenoma also does not show calcifications.

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

PMNs phagocytise debris and kill bacteria via free radicals (AKA respiratory burst). They also break down damaged tissue. PMNs typically undergo apoptosis after 48 hours. They are then engulfed and degraded by macrophages. Macrophages therefore become the predominant cell type in the wound on days 3-4.

Factors that increase the risk of ovarian cancer include nulliparity, IUD, endometriosis, cigarette smoking, HRT and obesity.

Choriocarcinoma spreads hematogenously.

Pain upon movement of the cervix with the health care provider’s gloved fingers is suggestive of an inflammatory process of the pelvic organs. CMT, when present, is classically found on bimanual examination of the cervix and uterus. While CMT is often associated with pelvic inflammatory disease, it can be present in other disease entities such as ectopic pregnancy, endometriosis, ovarian torsion, appendicitis, and perforated abdominal viscus.

PID is not a singular disease entity but describes a spectrum of disease. It is an upper genital tract infection, which may affect the uterus, fallopian tubes, ovaries, and peritoneum. PID can begin as cervicitis, progress to endometritis, followed by involvement of the fallopian tubes as pyosalpinx, and ultimately involve the ovary as a tubo-ovarian abscess (TOA). The two most common causative pathogens are N. gonorrhoeae and C. trachomatis although the infection is often polymicrobial.

Documentation of infection with either of these two organisms must be done by cervical swabs for culture.

Transvaginal ultrasound or CT scan can be done to confirm diagnosis however the absence of findings in these investigations doesn’t rule out the possibility of PID.

Urinalysis can be done to exclude urinary tract infection, one of the possible differential diagnosis for PID.

Thyroid stimulating hormone has no role in the diagnosis of PID.

The incubation period of varicella is 10-21 days.

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.

Beta Thalassaemia is autosomal recessive.

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.

Genital folds lead to the formation of the scrotum in males while in females they form the posterior labial commissure. Genital tubercles form the labia majora whereas the tubercle itself becomes the mons pubis. The labia minora is formed by the urogenital folds.

The third stage of labours starts from the delivery of the foetus to the delivery of the placenta and the membranes.

Erb’s or Erb-Duchenne palsy is a type of brachial plexus injury. The brachial plexus comprises C5 to T1 nerve roots. In Erb’s palsy C5 and C6 are the roots primarily affected. Shoulder Dystocia is the most common cause of Erb’s palsy.

About 97% of the testosterone that is secreted loosely binds to the SHBG and circulates in the blood for several hours in this bound state until it is transported to the target organs.

A rectovaginal swab taken for Group B streptococci culture should be done in women presenting with threatened preterm labour

If labour is establishes, intrapartum antibiotic prophylaxis for Group B streptococci should be commenced and continued until delivery. In cases were labour is not establish, prophylaxis for Group B streptococci should be ceased and should be re-established only if the culture is found to be positive, that too at the time of onset of labour.

Strategies acceptable for reducing early onset Group B streptococci sepsis includes universal culture-based screening using combined low vaginal plus or minus anorectal swab at 35-37 weeks gestation or a clinical risk factor based approach.

No additional prophylaxis is recommended irrespective of Group B streptococci carriage, for elective cesarean section before the commencement of labour. However, if a woman who commences labour or has spontaneous rupture of the membranes before her planned Caesarean section is screened positive for Group B streptococci, she should receive intrapartum antibiotic prophylaxis while awaiting delivery.

Although there is little direct evidence to guide this practice, consideration of the above mentioned evidences it is recommendation that, every women with unknown Group B streptococci status at the time of delivery should be managed according to the presence of intrapartum risk factors.
All women at increased risk of early onset Group B streptococci sepsis must be offered an intrapartum antibiotic prophylaxis with IV penicillin-G or ampicillin.

The best time to perform amniocentesis is at the gestational age of 15 weeks or more. There is increased risk of abortion, respiratory problems and fetal talipes if amniocentesis is performed before the gestational age of 14 weeks.

Transitional cell carcinoma of the bladder is most commonly caused by cigarette smoke. Other risk factors include naphthylamine, azodyes and long term cyclophosphamide use.

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.

The substructures of the nephrons are mainly located within the cortex. The JGA sits next to the glomerulus in the cortex (click on the magnifying glass of the image to see the arrangement). They play an important role in blood pressure homeostasis as the juxtaglomerular cells produce renin. The descending and ascending limbs of the loop of Henle and collecting ducts have sections within both the cortex and medulla

The most common clinical findings in a postpartum women with endometritis are postpartum fever, with tachycardia relative to the rise in temperature, midline lower abdominal pain and uterine tenderness from the 2nd to 10th day of postpartum.

Most common risk factors for the development of postpartum endometritis are:
– Cesarean deliveries are considered as the most important risk factor for postpartum endometritis, especially those performed after the onset of labour.
– Young maternal age.
– Multiple digital cervical examinations.
– Prolonged rupture of membranes.
– Retention of placental products.
– Prolonged labour.
– Chorioamnionitis.
Advanced maternal age is not considered as a risk factor for development of postpartum endometritis.

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.

Breakthrough bleeding, breast tenderness, nausea, bloating, amenorrhea, hypertension, venous thromboembolic disease, increased risk of cervical cancer with decreased risk of ovarian & endometrial cancer, liver disorders like hepatic adenoma and increase in triglycerides due to estrogen component are the common side effects & risks of using combination oral contraceptives.

Patient in the given case mentioned symptoms of primary dysmenorrhea, which is recurrent lower abdominal pain associated with menstruation. Combination estrogen-progestin oral contraceptive pills (OCPs) are considered as the first-line treatment for dysmenorrhea in sexually active patients as OCPs help to reduce pain by thinning the endometrial lining, reducing prostaglandin release and by decreasing uterine contractions.
Nausea, bloating and breast tenderness, are considered as the early side effects of OCPs and will usually improve with continued use. The most common side effect is breakthrough bleeding which is usually associated with lower estrogen doses and other adverse effects caused by the pills include hypertension, increased risk of cervical cancer and venous thromboembolism. Although common perception considers weight gain as a side effect, several studies have shown that no significant weight gain is associated with OCPs, particularly with low-dose formulations.  Considering this, the patient should be reassured that her weight gain is not associated with regular use of OCPs.

In patients who are not sexually active, nonsteroidal anti-inflammatory drugs are considered as the first-line treatment for primary dysmenorrhea. As stopping contraception will increase this Patient’s risk of unintended pregnancy this is not advisable to her.

Switching the patient to a copper intrauterine device (IUD) will decrease systemic side effects, but as its inflammatory reaction in the uterus may increase pain symptoms, copper IUD is not recommended for patients with dysmenorrhea.

As Medroxyprogesterone will increase body fat and decrease lean muscle mass resulting in weight gain is not a good option for this patient. Also medroxyprogesterone due to its risk of significant loss of bone mineral density, is not recommended for adolescents or young women. So it can be used in this age group only if other options are unacceptable.

Presence of estrogen component is the main reason behind the side effects of combination OCPs. Progesterone-only pills have relatively fewer side effects but as they do not inhibit ovulation, they are less effective for treating dysmenorrhea and for contraception.

Combination oral contraceptive pills are the first-line therapy for primary dysmenorrhea in sexually active patients.  Its side effects include breakthrough bleeding, hypertension, and increased risk of venous thromboembolism. Researches proves that weight gain is usually not an adverse effect of OCPs.

Pituitary tumours, the most common pathologic cause of galactorrhoea can result in hyperprolactinemia by producing prolactin or blocking the passage of dopamine from the hypothalamus to the pituitary gland. Approximately 30 percent of patients with chronic renal failure have elevated prolactin levels, possibly because of decreased renal clearance of prolactin. Primary hypothyroidism is a rare cause of galactorrhoea in children and adults. In patients with primary hypothyroidism, there is increased production of thyrotropin-releasing hormone, which may stimulate prolactin release. Nonpituitary malignancies, such as bronchogenic carcinoma, renal adenocarcinoma and Hodgkin’s and T-cell lymphomas, may also release prolactin.

As this is a simple cyst less than 50mm in diameter the patient does not require further investigation or routine follow up

As B-HCG and TSH have similar structures, increased B-HCG can lead to hyperthyroidism, however there is only a 3% chance of this happening.

Primary hyperparathyroidism is the most common cause of hypercalcemia. It is usually caused by a tumour of the parathyroid gland. Symptoms are related to increased calcium levels which can cause kidney stones, abdominal groans, psychiatric overtones and bones disease such as osteoporosis,osteomalacia and arthritis.

The correct answer is reassurance after thorough examination. Most breast lesions diagnosed during pregnancy and lactation, even some specific ones such as lactation and adenoma galactocele, are benign. The diagnosis of breast cancer, which is difficult to elucidate and is less common among women who are pregnant or lactating than among those of the same age who are not, continues to be a challenge for clinicians.

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.

These are the most common ovarian tumours in young women. The most common form is the mature dermoid cyst (cystic teratoma). It can consist of a combination of all the type of tissues (mesenchymal, stromal and epithelial). Any mature tissue type can be present such as muscle, cartilage, bone, teeth and often hair. Treatment is cystectomy.

Menstrual cycle can be divided into the follicular phase and luteal phase. In the luteal phase, there is an increase in progesterone secretion and LH levels are low. If the ova is fertilized, it is implanted in the endometrium. In case of failure in fertilization, there is gradual decrease in progesterone and LH levels.

This patient presents because of significant mood changes since she gave birth to her child: she is sad most of times and she is having guilt feelings about her adequacy for motherhood- She is also complaining of insomnia, tiredness, and even some suicidal ideation. These symptoms are highly suggestive postpartum depression. This should be differentiated from postpartum blues, which usually present within the first 2 weeks and last for few days. This patient’s symptoms started 5 weeks postpartum. Postpartum depression usually presents within the first 6 weeks to the first year postpartum.

Postpartum depression is the most common complication of childbearing and affects the mother, the child, and relationship with the partner. It is diagnosed the same way as major depressive disorder in other patients. Since untreated postpartum depression can have long-term effects on the mother and the child, appropriate therapy should be undertaken as soon as possible- Antidepressant medications such as sertraline can be used to treat postpartum depression. In a patient who has suicidal ideation, electroconvulsive therapy has a more rapid and effective action than medication and should be considered in these patients.

→ Cognitive behavioural therapy is effective in women with mild to moderate postpartum depression; it would not be a good choice in this patient with suicidal ideation and at risk of harming the baby.
→ Estrogen therapy used alone or in combination with antidepressant, has been shown to significantly reduce the symptoms of postpartum depression; however, it would not be the most appropriate choice in a patient with suicidal ideation.
→ Peer support has shown equivocal results in various studies even though most postpartum patients report that lacking an intimate friend or confidant or facing social isolation are factors leading to depression.
→ Non-directive counselling also known as ”listening visits“ has been found to be effective in postpartum patients, though the studies that were conducted are deemed to be of small sample and larger studies still need to be done to validate these findings. It would not be an appropriate choice for this patient with suicidal ideation.

Clomiphene shouldn’t be continued for more than 6 months. The second line options are Gonadotrophins or ovarian drilling.

The vaginal epithelium is made of squamous cells. Hence the most common carcinoma that occurs in the Vagina is squamous cell carcinoma. Diagnosis is made with vaginal biopsy. Usually the pain only presents if the disease extends beyond the vagina involving the perineal nerves.

This is a patient that recently gave birth and is still breastfeeding presenting with dyspareunia. The most likely cause would be a thin atrophic vaginal epithelium. This is very common presentation and is due to the low oestrogen levels due to the prolactin elevation from breastfeeding.

An unrecognised and unsutured vaginal tear should have healed by this time and should not be causing issues.

Endometriosis tends to resolve during a pregnancy, but if this was the issue, it would have caused dyspareunia prior to pregnancy.

Vaginal infective causes of dyspareunia, such as monilial or trichomonal infections, are rare in amenorrhoeic women.

Gestational diabetes (GDM) occurs in 2–9 per cent of all pregnancies. Screening for diabetes in pregnancy can be justify ed to diagnose previously unrecognized cases of pre-existing diabetes and to identify a group of women who are at risk of developing NIDDM later in life. No single screening test has been shown to be perfect in terms of high sensitivity and specific city for gestational diabetes. Urinary glucose is unreliable, and most screening tests now rely on blood glucose estimation, with an oral glucose tolerance test commonly used. The aim of glucose control is to keep fasting levels between 3.5 and 5.5 mmol/L and postprandial levels 7.1 mmol/L, with insulin treatment usually indicated outside these ranges.

Different changes can occur during the menstrual cycle including an increased body temperature at the time of ovulation, thinning of the cervical mucus and few other changes, but it is the LH surge which is the most important factor necessary for ovulation.
Mittelschmerz is characterised by recurrent midcycle pain which occurs around the time of ovulation.

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.

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 case is most likely diagnosed a threatened miscarriage.
A diagnosis of threatened miscarriage is made when there is uterine bleeding in the presence of a closed cervix and is confirmed by the sonographic visualisation of an intrauterine pregnancy with detectable fetal cardiac activity. Miscarriages may not always follow even though there was multiple episodes or large amounts of bleeding, therefore the term “threatened” is used in these cases.
At 7 to 11 weeks of gestation, about 90 to 96 percent cases of pregnancies, will not usually miscarry if they have presented with an intact fetal cardiac activity along with vaginal bleeding and if bleeding occurs at the later weeks of gestational age chances of success rate is higher.

Topic review:
– Inevitable miscarriages presents with a dilated cervix, increasing uterine bleeding and painful uterine contractions. The gestational tissues can often be felt or seen through the cervical os and its passage occurs within a short time.
– In Incomplete miscarriage, the membranes will rupture passing the fetus out, but significant amounts of placental tissue will be retained. This occurs most commonly in late first trimester or early second trimester. On examination, the cervical os will be opened and the gestational tissue can be observed in the cervix, with a uterine size smaller than expected for gestational age, but not well contracted. The amount of bleeding varies but can be severe enough to cause hypovolemic shock. There will be painful cramps
ontractions and ultrasound reveals tissue in the uterus.
– A missed miscarriage refers to the in-utero death of the embryo or fetus prior to 20th week of gestation, with retention of the pregnancy for a prolonged period of time. In this case, women may notice that symptoms associated with early pregnancy like nausea, breast tenderness, etc have abated and they don’t “feel pregnant” anymore.
Vaginal bleeding may occur but the cervix usually remains closed. Ultrasound reveals an intrauterine gestational sac with or without an embryonic/fetal pole, but no embryonic/fetal cardiac activity will be noticed.
– Complete miscarriage, usually occurs before 12 weeks of gestation and the entire contents of the uterus will be expelled resulting in a complete miscarriage. In this case, physical examination reveals a small, well contracted uterus with an open or closed cervix with scanty vaginal bleeding and mild cramping. Ultrasound will reveal an empty uterus with no extra-uterine gestation.

Genetically, patients suffering from androgen insensitivity syndrome are 46XY. They are males but insensitive to male hormones i.e. androgens.

The Vaginal artery, like the Uterine artery is typically a branch of the Internal Iliac artery. It can sometimes arise as a branch of the Uterine artery so it is important to read the question (if the stem stated it CAN arise from the Uterine artery then that would be true)

In a person who is infected by streptococcus (Group B) should be started on benzylpenicillin as soon as possible. In case of allergy vancomycin should be started at 1g every 12 hours. Tetracyclines should be avoided in pregnancy.

The normal fetal heart rate is between 110-150 bpm.

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

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

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

Bacterial vaginosis is characterised by a foul smelling vaginal discharge without inflammation. The most common spp to cause this is gardnerella vaginalis. Other spp include mycoplasma hominis and bacteroides. It occurs due to growth and increase in anaerobic spp with simultaneous reduction in lactobacilli in vaginal flora causing an increase in vaginal pH. It is the most common cause of abnormal vaginal discharge in women of childbearing age.

Trauma is a major contributor for maternal mortality and is one of the leading causes of pregnancy-associated maternal deaths.

As a result of maternal hypotension or hypoxemia, placental abruption, uterine rupture or fetal trauma a maternal trauma can compromise the fetus also.
Patient’s bruises on the abdomen which are seatbelt marks, are indications that this woman has positioned the seat belt incorrectly over the uterus. So there is a good chance that the uterus and its contents, including the fetus, has been affected by the impact. In a pregnant woman, the correct position of seat belt is when the lap belt is placed on the hip below uterus and the sash is placed between breasts and above the uterus.

A minimum of 24-hour period monitoring is recommended for all pregnant women, apart from the routine trauma workup indicated in non-pregnant women, in case they have sustained trauma in the presence of any of the following:
– Regular uterine contractions
– Vaginal bleeding
– A non-reassuring fetal heart rate tracing
– Abdominal/uterine pain
– Significant trauma to the abdomen

Considering the bruises over her abdomen this patient should be considered as having significant abdominal trauma and must be kept under observation for a minimum of 24 hours. Such patients should not be discharged unless the clinician makes sure they do not have any complications like abruption or preterm labor.

Serum prolactin levels are increased during suckling. Some other conditions in which serum prolactin is increased consist of: prolactin secreting brain tumours, anti psychotic drugs and hypothyroidism. It can also be increased in pregnancy, nipple stimulation and stress.

The postpartum period begins soon after the baby’s delivery and usually lasts six to eight weeks and ends when the mother’s body has nearly returned to its pre-pregnant state.

Bloody vaginal discharge (lochia rubra) is heavy for the first 3-4 days, and slowly it becomes watery in consistency and colour changes to pinkish-brown (lochia serosa). After the next 10-12 days, it changes to yellowish-white (lochia alba). Advise women to seek medical attention if heavy vaginal bleeding persists (soaking a pad or more in less than an hour). Women with heavy, persistent postpartum bleeding should be evaluated for complications such as retained placenta, uterine atony, rarely invasive placenta, or coagulation disorders. Endometritis may also occur, presenting as fever with no source, maybe accompanied by uterine tenderness and vaginal discharge. This usually requires intravenous antibiotics. This also should be explained and advise the mother to seek immediate medical attention.
