Progestin only pills increase the risk of developing follicular cysts. Sonographic studies have observed that follicular cysts are more common in POP users than women not using hormones. The follicular changes tend to increase and regress over time. No intervention is required in asymptomatic women, other than reassurance. POP users who have persistent concerns about ovarian follicular changes should be offered another method of contraception.

All other options are not contraindications to the use of mini-pills.

Ureters are muscular tubes that run from the kidneys to the urinary bladder. It is lined by transitional epithelium.

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.

The bladder is supplied by branches of the internal iliac artery, including the superior vesical artery, branches of the gluteal and obturator arteries and the inferior vesical artery in males and the vaginal and the uterine arteries in females.

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 the patient should use backup birth control, such as condoms, or avoid sexual intercourse until pills have been taken for seven diarrhoea-free days.

Options to stop pills are incorrect as it increases risk of pregnancy.

Turner syndrome, a condition that affects only females, results when one of the X chromosomes (sex chromosomes) is missing or partially missing. Turner syndrome can cause a variety of medical and developmental problems, including short height, failure of the ovaries to develop and heart defects. Streak ovaries are a form of ovarian dysgenesis and are associated with Turner syndrome. Occasionally they may be functional and secondary sexual characteristics may develop.

Radiotherapy works on the principle of ionisation. In particularly that of water leading to the formation of free radicals, these radicals are highly reactive and they react with the DNA leading to damage and cell death.

The Corpus Luteum is a temporary endocrine structure that secretes two steroid hormones: 1. Progesterone (17a Hydroxyprogesterone) and 2. Oestradiol. The corpus luteum also secretes Inhibin A. In the menstrual cycle if fertilisation doesn’t occur the corpus luteum stops secreting progesterone and degenerates into a corpus albicans. If fertilisation occurs hCG signals the corpus to continue progesterone production and it is then termed the corpus luteum graviditatis

Delayed puberty is defined as the absence of breast development in girls beyond the age of 13, and the absence of testicular development in boys beyond the age of 14. The incidence of delayed puberty is 3%, with the condition being more common in boys.

Due to the previous history of caesarean section, uterine rupture would be the most likely cause of bleeding in this patient who is at a prolonged active phase of first stage of labour.

Maternal manifestations of uterine rupture are highly variable but some of its common features includes:
– Constant abdominal pain, where the pain may not be present in sufficient amount, character, or location suggestive of uterine rupture and may be masked partially or completely by use of regional analgesia.
– Signs of intra abdominal hemorrhage is a strong indication. Although hemorrhage is common feature, but signs and symptoms of intra-abdominal bleeding in cases of uterine rupture especially in those cases not associated with prior surgery may be subtle.
– Vaginal bleeding is not considered as a cardinal symptom as it may be modest, despite major intra-abdominal hemorrhage.
– Maternal tachycardia and hypotension
– Cessation of uterine contractions
– Loss of station of the fetal presenting part
– Uterine tenderness
As seen in this case, fetal bradycardia is the most common and characteristic clinical manifestation of uterine rupture, preceded by variable or late decelerations, but there is no other fetal heart rate pattern pathognomonic of rupture. Furthermore, fetal heart rate changes alone have a low sensitivity and specificity for diagnosing a case as uterine rupture.
Pain and persistent vaginal bleeding despite the use of uterotonic agents are characteristic for postpartum uterine rupture. If the rupture extends into the bladder hematuria may also occur.
A definite diagnosis of uterine rupture can be made only after laparotomy. Immediate cesarean section should be performed to save both the mother and the baby in cases where uterine rupture is suspected.
