Herpes Simplex is which type of virus
Your Answer: double stranded RNA
Correct Answer: double stranded DNA
Explanation:Herpes simplex is a double stranded DNA virus. There are two viral types, HSV-1 and HSV-2. The majority of orolabial infections are caused by HSV-1. These infections are usually acquired during childhood through direct physical contact such as kissing. Genital herpes is a sexually transmitted infection and is most commonly caused by HSV-2.

Which of the following organisms causes Scarlet Fever?
Your Answer: Streptococcus epidermidis
Correct Answer: Streptococcus pyogenes
Explanation:Streptococcus pyogenes, also known as group A beta-haemolytic streptococcus, is the organism responsible for scarlet fever. The bacteria is found in secretions from the nose, ears or the skin, and infections may be preceded by wounds, burns or respiratory infections. Symptoms may include a sore throat, fever, a red skin rash and cervical lymphadenopathy. Untreated scarlet fever in children and adolescents can lead to rheumatic fever, or post-streptococcal glomerulonephritis.

A 32 year old mother is in her first trimester of pregnancy with her second child. She is worried about infections in this pregnancy as her daughter was born with a 'blueberry muffin rash' and was soon found to have sensorineural deafness due to an infection. Which of the following infections is most likely?
Your Answer: Rubella
Explanation:Congenital infections can be the cause of various congenital abnormalities. Infection with the Rubella virus, part of the TORCH infections (toxoplasmosis, other organisms, rubella, cytomegalovirus, and herpes simplex), can lead to cardiac abnormalities, ophthalmic defects, sensorineural deafness and neurodevelopmental delays. At birth congenital rubella syndrome presents with a petechial rash characteristically dubbed a blueberry muffin rash, and hepatosplenomegaly with jaundice. Immunization of the mother against measles is an effective way of reducing the occurrence of congenital rubella syndrome.

A 27-year-old woman presented to the clinic for advice because she is planning to conceive and has never been pregnant before. Upon history taking, it was noted that she has no history of diabetes, mental health issues, and is not taking any regular medication.
Which of the following is considered the best recommendation to give to the patient for the prevention of neural tube defects?Your Answer: Folic acid 5 mg daily after confirmed pregnancy
Correct Answer: Folic acid 0.4 mg daily for a minimum of one month before conception to first 12 weeks of pregnancy
Explanation:CDC urges all women of reproductive age to take 400 micrograms (mcg) of folic acid each day, in addition to consuming food with folate from a varied diet, to help prevent some major birth defects of the baby’s brain (anencephaly) and spine (spina bifida).
Women who are at high risk of having babies with neural tube defects and who would benefit from higher doses of folic acid include those with certain folate-enzyme genotypes, previous pregnancies with neural tube defects, diabetes, malabsorption disorders, or obesity, or those who take antifolate medications or smoke. Such women should take 5 mg/d of folic acid for the 2 months before conception and during the first trimester.

A 22 year old woman is being followed up 6 weeks after a surgical procedure to evacuate the uterus following a miscarriage. The histology has shown changes consistent with a hydatidiform mole. What is the single most appropriate investigation in this case?
Your Answer: Serum B-HCG
Explanation:The most appropriate test for a hydatiform mole is serum beta hCG levels, which are consistently raised in these patients. The levels return to normal when the pregnancy is terminated.

Which one of the following methods helps determine the fetal position and presentation?
Your Answer: Leopold's manoeuvre
Explanation:Fetal position and presentation is best evaluated by Leopold’s manoeuvre. It will determine which part of the foetus is in the uterine fundus.
Cullen’s sign is found in ruptured ectopic pregnancy characterised by bruising and oedema of the periumbilical region.
Mauriceau-Smelli-Veit manoeuvre is done during a breech delivery. -

What is the inferior border of the deep perineal pouch?
Your Answer: Superior fascia of the urogenital diaphragm
Correct Answer: Perineal membrane
Explanation:The perineal membrane (also known as the inferior fascia of the urogenital diaphragm) separates the deep and superficial perineal pouches i.e. it is the inferior border of the deep pouch and superior border of the superficial pouch. The deep perineal pouch is the space therefore between superior and inferior layers of the urogenital diaphragm The superior fascia of the urogenital diaphragm is the superior border

An 8-year-old girl presents with a history of a bright red bloodstain in her underpants one day prior to consultation. Her mother reports that the girl started cycling lessons one week ago. How will you proceed with the investigation in this case?
Your Answer: Local Examination
Correct Answer: Examination under Anaesthesia
Explanation:A local exam might not help in locating the cause of the bleeding because it might be underneath the superficial structures. A thorough examination should be done under GA to accurately locate the source of bleeding.

You are asked to speak to a 27 year old patient who is pregnant for the first time. She is concerned as her friend recently gave birth and the baby was found to have profound hearing loss. Her friend was told this was due to an infection whilst she was pregnant. What is the most common infective cause of congenital hearing loss?
Your Answer: Cytomegalovirus
Explanation:CMV is the most common congenital infection causing sensorineural deafness.
10-15% of infected infants will be symptomatic at birth. A further 10-15% who are asymptomatic at birth will develop symptoms later in life. Transmission can also be via breastmilk and the incubation period for CMV is 3-12 weeks. Diagnosis of fetal CMV infection is via amniocentesis however this should not be performed for at least 6 weeks after maternal infection and not until the 21st week of gestation -

Regarding fertilization & implantation:
Your Answer: The trophoblast invades the endometrium & differentiate into an outer cytotrophoblast & an inner cyncytiotrophoblast
Correct Answer: The sperm head penetrates through the corona radiata & zona pellucida while the tail remains outside
Explanation:During fertilization, a sperm must first fuse with the plasma membrane and then penetrate the female egg cell to fertilize it. Fusing to the egg cell usually causes little problem, whereas penetrating through the egg’s hard shell or extracellular matrix can be more difficult. Therefore, sperm cells go through a process known as the acrosome reaction, which is the reaction that occurs in the acrosome of the sperm as it approaches the egg. The acrosome is a cap-like structure over the anterior half of the sperm’s head. Upon penetration, if all is normally occurring, the process of egg-activation occurs, and the oocyte is said to have become activated. This is thought to be induced by a specific protein phospholipase c zeta. It undergoes its secondary meiotic division, and the two haploid nuclei (paternal and maternal) fuse to form a zygote. To prevent polyspermy and minimize the possibility of producing a triploid zygote, several changes to the egg’s cell membranes render them impenetrable shortly after the first sperm enters the egg.
