Regarding gestational diabetes which of the following is NOT a recognised risk factor
Your Answer: Previous unexplained stillbirth
Correct Answer: High polyunsaturated fat intake
Explanation: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. There are various risk factors for gestational diabetes including increasing age, ethnicity, previous still births etc.

A patient present to the clinic with a 1 day history of vaginal prolapse. Upon examination, the vagina is 1.5 cm below the vaginal plane. What grade is the prolapse according to the POP-Q classification?
Your Answer:
Correct Answer: Grade 3
Explanation:Pelvic organ prolapse is a common condition amongst ageing women where a weakness in the pelvic support structures of the pelvic floor allows pelvic viscera to descend.
The Pelvic Organ Prolapse Quantification system (POP-Q) is useful for describing and staging the severity of the pelvic organ prolapse.
Grade 1: the most distal portion of the prolapse is more than 1 cm above the level of the hymen
Grade 2: the most distal portion of the prolapse is 1 cm or less proximal or distal to the hymenal plane
Grade 3: the most distal portion of the prolapse protrudes more than 1 cm below the hymen but protrudes no farther than 2 cm less than the total vaginal length (for example, not all of the vagina has prolapsed)
Grade 4: vaginal eversion complete -

Which is the most useful tumour marker for monitoring of ovarian cancer patients?
Your Answer:
Correct Answer:
Explanation:CA-125 has found application as a tumour marker or biomarker that may be elevated in the blood of some patients with specific types of cancers, or other conditions that are benign. Increased level of CA125 appears in fifty percent of stage 1 ovarian cancer patients and more than 90% with stages 2-4 ovarian cancer. CA-125 is therefore a useful tool for detecting ovarian cancer after the onset of symptoms as well as monitoring response to treatment and for predicting a patient’s prognosis after treatment.

In the non-pregnant state which of the following hormones is secreted by the corpus luteum?
Your Answer:
Correct Answer: Progesterone
Explanation: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

Your Answer:
Correct Answer: Thyroid Stimulating Hormone (TSH)

The following are true for dizygotic twins EXCEPT:
Your Answer:
Correct Answer: Both twins are identical & of the same sex
Explanation:Dizygotic means two (di) fertilized eggs (zygotes). Dizygotic twins occur when two eggs are fertilized by two separate sperm. Dizygotic twins are also known as fraternal or non-identical twins. They are the most common type of twins.
Unlike monozygotic twins (also known as identical twins), dizygotic twins do not share the same genes. Monozygotic twins share 100 percent of each other genes. Dizygotic twins share only 50 percent. This is the same genetic similarity found between siblings conceived and born at different times.

A 28 year old patient has a diagnosis of PCOS. She has been trying to conceive for 2 years. Her BMI is 26 kg/m2 and she is a non-smoker. She has been taking Clomiphene and metformin for the past 6 months. What is the next most appropriate treatment?
Your Answer:
Correct Answer: Gonadotrophins
Explanation:Management of PCOS includes OCP, cyclical oral progesterone, metformin, clomiphene (which is more effective in inducing ovulation than metformin) and life-style changes. In women who are tolerant to these therapies Gonadotrophins should be trialled. However lifestyle changes should be able to improve the condition significantly. Clomiphene shouldn’t be continued for more than 6 months.

Fetal urine production starts at what gestation?
Your Answer:
Correct Answer: 8-11 weeks
Explanation:Fetal urine contributes significantly to amniotic fluid production in the second trimester of pregnancy. As early as 8-11 weeks, urine production begins and can be observed in the fetal bladder on ultrasound scans. The urine creates a hypotonic fluid which contains increasing concentrations of urea and creatinine. By term, a foetus produces about 800 ml of urine a day, of which 250ml is eliminated through fetal swallowing.
