A 33-year-old nulliparous pregnant female at the 21st week of pregnancy came to the gynaecological clinic for evaluation of vulval ulcer. A swab was taken revealing the herpes simplex type 2 virus. There is no prior history of such lesions and her partners of the last decade had no history of the infection. She's anxious about how she got the condition and the potential consequences for her and her unborn kid. Which of the following suggestions is the most appropriate?
Your Answer: The risk of neonatal herpes is much higher if there is a recurrence of previous genital herpes near the time of delivery than if a primary infection occurs at the time,
Correct Answer: The primary infection is commonly asymptomatic.
Explanation: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. -

Regarding the study of the prognosis of a disease, which of the following studies is most appropriate?
Your Answer: Case Control Studies
Correct Answer: Cohort Study
Explanation:Cohort studies are the most appropriate study design to study the prognosis of a disease. A group of patients with the same condition are chosen and their baseline information is taken. The group is then followed up over time to see which patients live or die.
Case-control studies can also be useful where a group of individuals that have survived a condition are compared with cases of those who have died. Prognostic factors that distinguish the two groups are identified. This method, however, is limited by bias and the accuracy of medical information present. -

A 24 year old lady is rushed to the emergency department complaining of vaginal spotting and abdominal cramping. Her 6 week pregnancy was confirmed by ultrasound scan last week. On speculum examination, the cervical os is open with blood noted around it.
Which of the following is the most likely diagnosis?Your Answer: Threatened Miscarriage
Correct Answer: Inevitable Miscarriage
Explanation:A miscarriage is defined as the spontaneous loss of a pregnancy before the age of viability at 24 weeks in the UK. An inevitable miscarriage occurs with the usual symptoms of a miscarriage such as menstrual-like cramping, vaginal bleeding and a dilated cervix. The gestational sac has ruptured but products of conception have not been passed. The products of conception will eventually pass.
A missed miscarriage is described as a loss of pregnancy without vaginal bleeding, loss of tissue, cervical changes or abdominal pain. During a scan, a fetal heartbeat is not observed, and the gestational sac may be small.
A threatened miscarriage is when the cervix dilates and uterine bleeding is seen; the pregnancy could still be viable.
A complete miscarriage occurs when all the products of conception are expelled from the uterus, bleeding has stopped, and the cervix has closed up after dilation. Recurrent miscarriages are described as spontaneous pregnancy loss of more than 2 to 3 consecutive times.

A 24-year-old on combined oral contraceptive pills for the last 3 years. She complains of migraine two to three times a month for the last 6 months.
What should be best appropriate advice to her?Your Answer: Stop combined oral contraceptive pills and prescribe progestogen only pills
Explanation:While on combination oral contraceptive tablets, this patient had a migraine. After a conversation about adverse effects, stop the combo medications and prescribe her progestogen-only pills.
The following are reasons why progestogen-only pills should be your first choice:
1-Age of 45 or more years
2-Smokers who are 45 years old or older
3-Oestrogen contraindications
4-Melitus Diabetes
5-A headache (combined oral contraceptive pills have absolute contraindication)
6-Hypertension under control
7-Lactation
8-Chloasma.Pregnancy, undetected genital tract bleeding, and concurrent use of enzyme-inducing medications are all contraindications to using progestogen-only pills.

A 28 year old primigravida carrying a twin pregnancy presents at 32 weeks gestation. She is lethargic, clinically jaundiced and complains of abdominal pain with frequent vomiting. A summary of her blood results are as follows: Elevated aspartate transaminase (AST) and alanine transaminase (ALT) levels · Decreased blood glucose levels · Elevated levels of blood ammonia. What is the likely diagnosis?
Your Answer: Acute fatty liver of pregnancy
Explanation:This patients bloods and symptoms suggest she has hepatic impairment. Acute fatty liver of pregnancy typically presents after the 30th week. The usual symptoms in the mother are non-specific including nausea, vomiting, anorexia (or lack of desire to eat) and abdominal pain; excessive thirst may be the earliest symptom without overlap with otherwise considered normal pregnancy symptoms; however, jaundice and fever may occur in as many as 70% of patients.
Many laboratory abnormalities are seen in acute fatty liver of pregnancy. Liver enzymes are elevated, with the AST and ALT enzymes ranging from minimal elevation to 1000 IU/L, but usually staying in the 300-500 range. Bilirubin is almost universally elevated. Alkaline phosphatase is often elevated in pregnancy due to production from the placenta, but may be additionally elevated. Other abnormalities may include an elevated white blood cell count, hypoglycemia, elevated coagulation parameters, including the international normalized ratio, and decreased fibrinogen. There may be increases of ammonia, uric acid aswell.
Recent studies have shown that being a primigravida, multiple pregnancies, carrying a male fetus, other liver diseases during pregnancy, previous history of AFLP, and pre-eclampsia are the potential risk factors for AFLP

You are asked to consult on a young woman with a pre-existing cardiac defect. She wants to become pregnant in the near future and seeks advice about what risks to her health that this will create. You tell that the highest maternal mortality rates are associated with which of the following cardiac defects:
Your Answer: Mitral stenosis
Correct Answer: Eisenmenger syndrome
Explanation:Eisenmenger’s syndrome is one where there is communication between the systemic and pulmonary system, along with increased pulmonary vascular resistance, either to systemic level or above systemic level (right to left shunt). A would-be mother must be informed that to become pregnant would incur a 50% risk of dying. Even if she survives, fetal mortality approaches 50% as well.
– Severe symptomatic aortic stenosis has a mortality in pregnancy of about 20%. Prevention of reduction in preload is necessary in all obstructive cardiac lesions. Balloon valvuloplasty can be done in pregnancy.
– Due to the increased blood volume and cardiac output in pregnancy, mitral stenosis can lead to severe pulmonary oedema. Balloon valvuloplasty can be done in pregnancy.
– Ebstein anomaly is a malformation of the tricuspid valve- It is usually not associated with maternal mortality.
– Atrial-septal defects rarely cause complications in pregnancy, labour, or delivery. -

Which structure is the primary mechanism for shunting blood away from the fetal pulmonary circulation?
Your Answer: Ductus Arteriosus
Correct Answer: Foramen Ovale
Explanation:Oxygenation of fetal blood occurs in the placenta before it returns in the umbilical vein which joins the left branch of the portal vein. It bypasses the capillaries of the liver by going through the ductus venosus, which is obliterated after birth and becomes the ligamentum venosum. The oxygenated blood enters the inferior vena cava and is transported to the right atrium and
then through the patent foramen ovale to the left atrium and on to the left ventricle. From the left ventricle, the blood flows into the aorta and through the fetal vascular network. Blood returning from the head of the foetus passes through the superior vena cava to the right atrium and straight on to the right ventricle and pulmonary artery. However, it does not enter the pulmonary
circulation, being short-circuited by the ductus arteriosus to the aorta. Aortic blood is carried via the umbilical arteries back to the placenta for reoxygenation. At birth, the three short circuits, the ductus venosus, foramen ovale and ductus arteriosus, close. -
