In the given case, the patient should be treated with Augmentin.
Asymptomatic bacteriuria occurs in about 2 % to 10 % of all pregnancies and if left untreated, about 30% of this will develop acute cystitis and the other 50% will develop acute pyelonephritis.

Escherichia coli is the most common pathogen associated with asymptomatic bacteriuria, which consists more than 80% of the isolate and Staphylococcus Saprophyticus accounts for about 5-10% of isolates associated with uncomplicated UTI. Escherichia coli is a very common normal flora found in the gastrointestinal tract and Staphylococcus Saprophyticus is a commonly found normal flora in genital tract and perineum.

Asymptomatic bacteriuria has found to be associated with low birth weight and preterm birth, and it is found that a short term antibiotic treatment will help in improving the fetal outcomes in cases of asymptomatic bacteriuria or uncomplicated UTI. Hence, all cases of asymptomatic bacteriuria and uncomplicated UTI during pregnancy are recommended to be treated with a five day course of oral antibiotics as this is normally sufficient in pregnant women.

Drug of choice in asymptomatic bacteriuria (directed therapy based on sensitivities) in case of E. coli are either:
– Cephalexin 500 mg oral twice a day for 5 days or
– Nitrofurantoin 100 mg orally twice daily for 5 days or
– Trimethoprim 300 mg oral doses daily for 5 days (avoided during first trimester and in those pregnant women with established folate deficiency, low dietary folate intake, or for women taking other folate antagonists).
– Amoxicillin + clavulanate 500 + 125 mg oral, twice daily for 5 days if < 20 weeks of gestation.
Note: In view of childhood outcomes – (ORACLE II trial and 7 year follow-up), which showed an associated increase in necrotising enterocolitis, functional impairment (low), and cerebral palsy, it is recommended that amoxicillin / clavulanate is only used if no alternative treatment is available(if >20 weeks of gestation).

Asymptomatic bacteriuria (directed therapy based on sensitivities ) in case of Staphylococcus saprophyticus infection is as follows:
Cephalexin 500 mg oral doses twice a day for 5 days or Amoxicillin 500mg TDS for 5 days.

Asymptomatic bacteriuria (directed therapy based on sensitivities) in case of infection with Pseudomonas suggest Norfloxacin 400 mg oral twice daily for 5 days, then repeat MSSU 48 hours after the treatment is completed.

In case of Group B streptococcus as a single organism, Penicillin V 500 mg oral twice daily for 5 days. If the patient is hypersensitive to penicillin give Cephalexin 500 mg orally twice a day for 5 days were immediate hypersensitivity is excluded. If immediate hypersensitivity to penicillin is noticed, then Clindamycin 450 mg three times daily for 5 days is advised.

Amoxicillin is found more effective in treating UTIs caused by organisms which are resistant to the drug in vitro because of its high concentrations attainable in urine. However, a study shows that amoxicillin-resistant organisms do not respond to amoxicillin alone but Augmentin [amoxicillin clavulanate] is found to cure urinary tract infection irrespective of the amoxicillin susceptibility of the organism in vitro. Of the patients infected with amoxicillin-resistant organisms, 80% were cured by augmentin and only 10% with infection by amoxicillin-resistant organisms were cured by amoxicillin.

Now a days Amoxicillin is not preferred as the common treatment option for UTI due to increasing incidences of Escherichia coli resistance, which accounts majority of uncomplicated urinary tract infections. Clavulanic acid which is a beta-lactamase inhibitor works synergistically with amoxicillin to extend spectrum antibiotic susceptibility. This makes UTIs less likely to be resistant to the treatment with amoxicillin clavulanate compared to amoxicillin alone.
Ciprofloxacin and Gentamicin which are the other antibiotic choice considered otherwise also should be avoided in pregnancy as they comes under FDA pregnancy Category C.

Patient’s presentation and physical examination findings are most consistent with physiologic dyspnea, which is common during pregnancy. This breathing difficulty which is due to an increase in the tidal volume of lung will present itself as an increased awareness of breathing and can occur as early as the end of first trimester. Any minute increase in the ventilation occurs during pregnancy can make patients feel as if they are hyperventilating and contribute to the feeling of dyspnea.

Patient should be reassured and educated regarding these normal changes of pregnancy, also should be counselled to modify her exercise regimen accordingly to her changed tolerance.

Systolic ejection murmurs are due to increased blood flow across the aortic and pulmonic valves which is a normal finding in a pregnancy. So there is no need for this patient to be referred to a cardiologist or to order an ECG.
About 1 in 6400 pregnancies present with pulmonary embolism and there will be clinical evidence of DVT in many of these cases. Dyspnea, chest pain, apprehension, cough, hemoptysis, and tachycardia are the most common symptoms of PE and physical examination shows accentuated pulmonic closure sound, rales, or a friction rub. If there is a strong suspicion for PE, the patient should be followed up with a ventilation-perfusion scan, which will confirm PE if presented with large perfusion defects and ventilation mismatches.

At 12 weeks gestation the fundus is expected to be palpable above the pubis symphysis and it is expected to be felt at the level of umbilicus by 20 weeks. Though the uterine fundus stands in between from 12 and 20 weeks, the height of the fundus in centimeters is equivalent to the weeks of pregnancy after 20 weeks.

For 14-week pregnant uterus a fundal height of 18cm is definitely large and dating errors is considered as the most common cause for such a discrepancy. Hence, it is better to perform an ultrasound scan for more accurately estimating the gestational age. Also if the case is not a simple dating error, ultrasonography can provide definitive additional information about other possible conditions such as polyhydramnios, multiple gestation, etc that might have led to a large-for-date uterus.

A large-for-gestational-age uterus are most commonly found in conditions like:
– Dating errors which is the most common cause
– Twin pregnancy
– Gestational diabetes
– Polyhydramnios
– Gestational trophoblastic disease, also known as molar pregnancy

In pregnancy, the uterus increases in size to accommodate the developing foetus. At 16 weeks gestation, the fundus of the uterus must be palpated at the midpoint between the umbilicus and the pubic symphysis but the patient’s uterus was already palpable at just 11 weeks.

If less than seven weeks pregnant, it’s unlikely to find a heartbeat by ultrasound. Using transvaginal ultrasound, a developing baby’s heartbeat should be clearly visible by the time a woman is seven weeks pregnant. Abdominal ultrasound is considerably less sensitive, so it can take longer for the heartbeat to become visible. If past seven weeks pregnant, seeing no heartbeat may be a sign of miscarriage.

Fetal viability is confirmed by the presence of an embryo that has cardiac activity. Cardiac activity is often present when the embryo itself measures 2 mm or greater during the 6th week of gestation. If cardiac activity is not evident, other sonographic features of early pregnancy can predict viability.

It is recommended that all pregnant women undergo a routine ultrasound at 10 to 13 weeks of gestation to determine an accurate gestational age. Getting an accurate gestational age is highly important and pertinent for the optimal assessment of fetal growth later in pregnancy. Ultrasound is the most reliable method for establishing a true gestational age by measurement of crown-rump length, which can be measured either transabdominally or transvaginally.

Indication for a transvaginal ultrasound during pregnancy include:
– to monitor the heartbeat of the foetus
– look at the cervix for any changes that could lead to complications such as miscarriage or premature delivery
– examine the placenta for abnormalities
– identify the source of any abnormal bleeding
– diagnose a possible miscarriage
– confirm an early pregnancy

This is an ultrasound examination that is usually carried out vaginally at 6-10 weeks of pregnancy.

The aims of this scan are to determine the number of embryos present and whether the pregnancy is progressing normally inside the uterus.

This scan is useful for women who are experiencing pain or bleeding in the pregnancy and those who have had previous miscarriages or ectopic pregnancies.

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

Cord entanglement, a condition unique to MoMo pregnancies, occurs in 42 to 80% of the cases and it has been traditionally related to high perinatal mortality. Umbilical cord entanglement is present in all monoamniotic twins when it is systematically evaluated by ultrasound and colour Doppler. Perinatal mortality in monoamniotic twins is mainly a consequence of conjoined twins, twin reversed arterial perfusion (TRAP), discordant anomaly and spontaneous miscarriage before 20 weeks’ gestation. Expectantly managed monoamniotic twins after 20 weeks have a very good prognosis despite the finding of cord entanglement. The practice of elective very preterm delivery or other interventions to prevent cord accidents in monoamniotic twins should be re-evaluated.

Women with diabetes have increased risk for adverse maternal and neonatal outcomes and similar risks are present for either type 1 or type 2 diabetes. Both forms of diabetes require similar intensity of diabetes care. Preconception planning is very important to avoid unintended pregnancies, and to minimize risk of congenital defects. Haemoglobin A1c goal at conception is <6.5% and during pregnancy is <6.0%.

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 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.

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.

Engagement means when the fetal head enters the pelvic brim/inlet and it usually takes place 2 weeks before the estimated delivery date i.e. at 38 weeks of pregnancy.

Twin gestations are generally at increased risk of complications and this risk is further stratified based on the chorionicity ie. number of placentas and amnionicity, the number of amniotic sacs of the gestation. In the given case patient has monochorionic diamniotic twins, which means 1 placenta and 2 amniotic sacs, based on the presence of 2 embryos, a single placenta and a thin intertwin membrane composed of 2 amniotic sacs that meets the placenta at a 90-degree angle (“T sign”). In patients who appear to have a single placenta, the base shape of the intertwin membrane distinguishes between a monochorionic (“T sign”) and fused dichorionic (“lambda sign”) gestation.
Monochorionic twins are at high risk for twin-twin transfusion syndrome (TTTS), which is a complication that can result in heart failure and fetal
eonatal mortality in both twins. In TTTS, unbalanced arteriovenous anastomoses are present between the shared placental vessels that supply the twins, because of these anastomoses, blood from the placental arteries from one twin (donor), which is of high resistance/pressure, is shunted into the placental veins of the other twin (recipient) with low resistance/pressure. This shunting of blood away from the donor twin causes anemia that leads to renal failure, oligohydramnios, low-output heart failure, and fetal growth restriction. In contrast, the shunting of blood toward the recipient twin causes polycythemia, which leads to polyhydramnios, cardiomegaly, high-output heart failure and hydrops fetalis. This in turn makes both twins at high risk for intrauterine and neonatal death.
Mild TTTS is expectantly managed with serial ultrasounds to evaluate for worsening clinical features, whereas moderate-to-severe cases are treated with laser coagulation of the placental anastomoses.

In monozygotic twins, placentation type is determined by timing of the twinning.  Twinning that occurs shortly after fertilization yields a dichorionic diamniotic gestation.  In contrast, the incomplete division (ie, fission) that can lead to conjoined twins occurs later in development and yields a monochorionic monoamniotic gestation. As the twins are in the same sac, monochorionic monoamniotic gestations can be complicated by cord entanglement but not possible in the given case as this patient has diamniotic twins.

Risk factors for placenta accreta, implantation of the placenta directly into the myometrium, include placenta previa and prior uterine surgeries like cesarean delivery, myomectomy, etc

Twin pregnancies are at increased risk of placenta previa (placental tissue that covers the internal cervical os); however, this patient has a fundal placenta, making this complication unlikely.

Monochorionic twin gestations can be complicated by twin-twin transfusion syndrome, which is potentially a fatal condition that results from unbalanced vascular anastomoses between the vessels supplying umbilical cords of each twin.

The correct answer is Obstetric Cholestasis.
The characteristics (elevated bile acids, conjugated bilirubin, and alkaline phosphatase (ALP) levels) are typical with obstetric cholestasis, which affects roughly 3-4 percent of pregnant women in Australia. Obstetric cholestasis is diagnosed when otherwise unexplained pruritus occurs in pregnancy and abnormal liver function tests (LFTs) and/or raised bile acids occur in the pregnant woman and both resolve after delivery. Pruritus that involves the palms and soles of the feet is particularly suggestive.
Liver function tests and bile acid levels measurements are used to validate this diagnosis.
All of the other diagnoses are theoretically possible, but unlikely.
On liver function tests, hepatitis A and acute fatty liver of pregnancy (which is frequently associated with severe vomiting in late pregnancy) usually show substantially worse hepatocellular damage.
Pre-eclampsia is connected with hypertension and proteinuria (along with changes in renal function and, in certain cases, thrombocytopenia), while cholelithiasis is associated with obstructive jaundice and pale stools due to a stone in the CBD.

The patient most likely suffered a uterine rupture. It occurs most often in multiparous women and is less often associated with external haemorrhage. Shock develops shortly after rupture due to the extent of concealed bleeding.

Uterine inversion rarely occurs when after a spontaneous and normal third stage of labour. Although it can lead to shock, it is usually associated with a history of controlled cord traction or Dublin method of placenta delivery before the uterus has contracted. This diagnosis is also strongly considered when shock is out of proportion to the amount of blood loss.

An overwhelming infection is unlikely in this case when labour occurred for a short period of time. Uterine atony and amniotic fluid embolism are more associated with excessive vaginal bleeding, which is not evident in this case.

Magnesium Sulphate is the drug of choice in eclamptic patients. A loading dose of 4g magnesium sulphate in 100mL 0.9% saline IVI over 5min followed by maintenance IVI of 1g/h for 24h. Signs of toxicity include respiratory depression and jerky tendon reflexes. In recurrent fits additional 2g can be given. Magnesium should be stopped when the respiratory rate is <14/min, absent tendon reflexes, or urine output is <20mL/h.

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.

Pregnant women need to get enough folic acid. The vitamin is important to the growth of the foetus’s spinal cord and brain. Folic acid deficiency can cause severe birth defects known as neural tube defects. The Recommended Dietary Allowance (RDA) for folate during pregnancy is 600 micrograms (µg)/day.

Opiates and spinal anaesthetics reduce the variability of a CTG. Including some antihypertensives like labetalol and alpha methyl dopa.

Adnexa refer to the anatomical area adjacent to the uterus, and contains the fallopian tube, ovary, and associated vessels, ligaments, and connective tissue. The reported incidence of adnexal masses in pregnancy ranges from 1 in 81 to 1 in 8000 pregnancies. Most of these adnexal masses are diagnosed incidentally at the time of dating or first trimester screening ultrasound (USS). Functional cyst is the most common adnexal mass in pregnancy, similar to the nonpregnant state. A corpus luteum persisting into the second trimester accounts for 13-17% of all cystic adnexal masses. Pain due to rupture, haemorrhage into the cyst, infection, venous congestion, or torsion may be of sudden onset or of a more chronic nature.
