    Correct

    • A 6 year old boy presented in the emergency department with a cough and knee swelling after falling on the road. He had a non-blanching rash on his buttocks and investigations revealed: PT=13, APTT=71, Hgb=11, WBC=8, Plt=200. Which is the most likely diagnosis?

      Your Answer: Haemophilia

      Explanation:

      From the options mentioned here, the closest diagnosis is haemophilia. This is a mixed picture, as a purpuric rash on the buttocks does not correlate with this diagnosis. However, the most appropriate diagnosis is haemophilia.

      Your Answer: Over-riding aorta

      Correct Answer: Pulmonary stenosis

      Explanation:

      The overall diagnosis is Fallot’s tetralogy. Ventricular septal defect with left to right shunt is indicated by drop of oxygen saturation from left atrium to left ventricle. Pulmonary stenosis is indicated by the pressure difference between the pulmonary artery and the right atrium. There is oxygen saturation drop from the left ventricle to the aorta which can be due to the overriding aorta.

    Incorrect

    • A well preterm baby in a thermo-neutral environment requires how much energy to maintain essential body functions?

      Your Answer: 100kcal/kg/day

      Correct Answer: 50kcal/kg/day

      Explanation:

      The average amount of energy required by a well preterm baby in a thermo-neutral environment is 50/kcal/kg to maintain essential body functions while it takes about 70 kcal/kg/day for optimal growth. It is important to ensure that enough proteins are given per calorie to limit catabolism and promote cell building. Caloric need usually increases when the baby is ill.

    Incorrect

    • A term baby is admitted to NICU from the postnatal ward following a large green vomit. The baby was born by forceps delivery following non-reassuring CTG trace. There was meconium-stained liquor just before delivery. Respiratory rate is 60/min, heart rate is 180/min and oxygen saturations are 94% in room air. On examination baby appears quiet with mild nasal flaring. There are no other signs of increased work of breathing. Heart sounds are normal with no murmurs. Femoral pulses are palpable bilaterally. CRT is <2 seconds centrally and baby feels warm peripherally. Abdomen is slightly distended and baby desaturates to 80% on abdominal palpation. What is the most important diagnostic test?

      Your Answer: Abdominal X-Ray

      Correct Answer: Upper GI contrast study

      Explanation:

      Bilious (green) gastric aspirate or emesis indicates that the intestines are obstructed below the ampulla of Vater.Gastrointestinal (GI) endoscopy is actually considered an essential diagnostic and therapeutic technique. Upper GI endoscopy in neonatal age allows for exploration of the oesophagus, stomach and duodenum| instead lower GI endoscopy easily reaches the sigmoid-colon junction.

    Incorrect

    • A pregnant woman with atopic eczema and asthma, who has a 5-year-old child with moderately severe eczema, requests advice about reducing the risk of eczema in her unborn child. Select the MOST appropriate advice from the following:

      Your Answer: In high-risk families, there is evidence to support prolonged exclusive breastfeeding (i.e. beyond 6 months) as a preventive measure

      Correct Answer: Removing certain known food allergens from the mother’s diet during pregnancy does not reduce the risk or prevent the onset of atopic eczema

      Explanation:

      Nonspecific triggers of inflammation in patients with atopic dermatitis may include physical or chemical irritants. The following simple measures should be followed in daily life to reduce the frequency and severity of irritant-induced atopic dermatitis flares :Skin care products that contain alcohol and astringents should be avoided.New clothes should be laundered before use to remove formaldehyde and other chemicals.Liquid detergents are preferred over powder detergents for laundering clothes, as liquids are easier to rinse out. A second rinse cycle may also improve removal of residual detergent.Patients should shower immediately after swimming in chlorinated pools and should subsequently apply moisturizer.Fragrance-free skin products that are hypoallergenic or made for sensitive skin may be less irritating than other kinds of skin products.Prenatal and postnatal probiotic supplementation may be helpful in preventing the development of atopic dermatitis in young children. In a 2008 meta-analysis, the most commonly studied probiotic was Lactobacillus rhamnoses GG. Larger, randomized controlled studies are needed to confirm these initial findings.Breastfeeding during the first 4 months of life may reduce the incidence and severity of childhood atopic disease but only modestly and only in those at high risk.

    • A 13-year-old girl presents with a swollen left knee following a fall. Her parents state she suffers from haemophilia and has been treated for a right-sided haemarthrosis previously. What other condition is she most likely to have?

      Your Answer: Hunter's syndrome

      Correct Answer: Turner's syndrome

      Explanation:

      Haemophilia is a X-linked recessive disorder. In X-linked recessive inheritance only males are affected. An exception to this seen in examinations are patients with Turner’s syndrome, who are affected due to only having one X chromosome. X-linked recessive disorders are transmitted by heterozygote females (carriers) and male-to-male transmission is not seen. Affected males can only have unaffected sons and carrier daughters.

    Correct

    • Which of the following is true regarding erythema nodosum?

      Your Answer: It is associated with streptococcal infections

      Explanation:

      Erythema nodosum (EN) is an acute, nodular, erythematous eruption that usually is limited to the extensor aspects of the lower legs. Chronic or recurrent erythema nodosum is rare but may occur.Currently, the most common cause of erythema nodosum is streptococcal infection in children and streptococcal infection and sarcoidosis in adults.The eruptive phase of erythema nodosum begins with flulike symptoms of fever and generalized aching. Arthralgia may occur and precedes the eruption or appears during the eruptive phase. Most lesions in infection-induced erythema nodosum heal within 7 weeks, but active disease may last up to 18 weeks. In contrast, 30% of idiopathic erythema nodosum cases may last more than 6 months. Febrile illness with dermatologic findings includes abrupt onset of illness with initial fever, followed by a painful rash within 1-2 days.

    Incorrect

    • Diffusion is the movement of molecules from a region of high concentration to a region of low concentration. Which of these changes will decrease the rate of diffusion of a substance?

      Your Answer: An increase in the concentration gradient

      Correct Answer: An increase in the molecular weight of the substance

      Explanation:

      Unless given IV, a drug must cross several semipermeable cell membranes before it reaches the systemic circulation. Drugs may cross cell membranes by diffusion, amongst other mechanisms. The rate of diffusion of a substance is proportional to the difference in the concentration of the diffusing substance between the two sides of the membrane, the temperature of the solution, the permeability of the membrane and, in the case of ions, the electrical potential difference between the two sides of the membrane.

    Incorrect

    • A 16-year-old boy presents with complaints of ear pain. The pain started last night and prevented him from sleeping. He reports that sounds are muffled on the affected side. On examination, he has a fever. A bulging tympanic membrane with a visible fluid level is seen on otoscopy. You suspect a diagnosis of acute suppurative otitis media. Tensor tympani is a muscle that is found in the middle ear. What is the nerve supplying the tensor tympani?

      Your Answer:

      Correct Answer: Mandibular nerve

      Explanation:

      The nerve supply to the tensor tympani is the mandibular nerve.The mandibular nerve is the only division of the trigeminal nerve that carries motor fibres.Tensor tympani is a muscle that lies in a bony canal just superior to the pharyngotympanic tube. It originates from the cartilaginous portion of the pharyngotympanic tube, the bony canal in which it sits, and the greater wing of the sphenoid bone. It inserts into the upper part of the handle of the malleus. When contracted, it pulls the handle of the malleus medially. This action increases the tension across the tympanic membrane, reducing the magnitude of vibrations transmitted into the middle ear. This dampens loud noises or noises produced by chewing. Tensor tympani is innervated through the nerve to tensor tympani, which arises from the mandibular nerve.Other options:- The vestibulocochlear nerve is the eighth cranial nerve. This nerve has two components, a vestibular division that carries balance information, and a cochlear division that carries hearing information.- The glossopharyngeal nerve is the ninth cranial nerve. It has a wide range of functions. It carries taste and sensation from the posterior third of the tongue, as well as sensation from the pharyngeal wall and tonsils, the middle ear, external auditory canal and auricle. It carries parasympathetic fibres that supply the parotid gland. It also supplies the baroreceptors and chemoreceptors of the carotid sinus and supplies the secretomotor fibres to the parotid gland.- The maxillary nerve carries only sensory fibres.- The facial nerve is the seventh cranial nerve. It supplies the muscles of facial expression, as well as stylohyoid, the posterior belly of digastric, and stapedius (the only other muscle associated with the middle ear). It carries taste from the anterior two-thirds of the tongue and sensation from part of the external acoustic meatus, parts of the auricle and the retro-auricular area. It provides secretomotor fibres which supply to the submandibular gland, sublingual gland (via chorda tympani nerve), nasal glands and lacrimal glands.

    Incorrect

    • An 8 year old child complains of pain in his ear. His overall health is normal and clinical examination reveals no discharge, hearing loss or fever. Just by looking at it, the pinna of the ear looks swollen and red. Also, pushing the tragus leads to pain. Otoscopy reveals an erythematous external auditory canal and an otherwise healthy tympanic membrane. The bony external canal courses through which bone?

      Your Answer:

      Correct Answer: Temporal bone

      Explanation:

      The external auditory canal (EAC) extends from the auricle to the tympanic membrane. Its lateral portion is fibrocartilaginous and its medial portion is bony. Its bony portion is formed by the tympanic portion of the temporal bone.

    • An 18-month-old boy of Asian descent and a product of non-consanguineous marriage presents to the clinic with a history of swelling of both wrists. He has been complaining of painful legs and his parents are concerned about his bandy legs. The child was breastfed until 6 months of age, with solids being introduced in the diet later. At 12 months of age the child suffered from a non-stick fracture of the radius after falling at the nursery. Which condition is the child most likely suffering from?

      Your Answer:

      Correct Answer: Vitamin D-deficient rickets

      Explanation:

      The signs and symptoms of vitamin D-dependent rickets begin within months after birth, and most are the same for all types of the condition. The weak bones often cause bone pain and delayed growth and have a tendency to fracture. When affected children begin to walk, they may develop abnormally curved (bowed) legs because the bones are too weak to bear weight. Impaired bone development also results in widening of the metaphysis, especially in the knees, wrists, and ribs. Some people with vitamin D-dependent rickets have dental abnormalities such as thin tooth enamel and frequent cavities. Poor muscle tone (hypotonia) and muscle weakness are also common in this condition, and some affected individuals develop seizures.

      Your Answer:

      Correct Answer: Periventricular cerebral calcifications are an associated feature

      Explanation:

      One of the most common congenital viral infections is cytomegalovirus infection. The infection is even commoner than the other widely known diseases like down’s syndrome and spina bifida. It is caused by herpesvirus type 5 and is diagnosed using PCR of saliva. The clinical features include failure to thrive, intellectual disability, epilepsy, and microcephaly. The most common clinical complication is sensorineural deafness. The drug of choice for the treatment of neonatal CMV infection is ganciclovir, an anti-viral drug that has shown to prevent deafness. Cytomegalic inclusion disease is diagnosed at birth with marked neurological disability, resulting from microcephaly, intracerebral calcifications, and cerebral atrophy.

      Your Answer:

      Correct Answer: Klinefelter's syndrome

      Explanation:

      The most overt phenotypic features of Klinefelter syndrome are caused by testosterone deficiency and, directly or indirectly, by unsuppressed follicle-stimulating and luteinizing hormones. Affected men typically have (in decreasing order of frequency): infertility, small testes, decreased facial hair, gynecomastia, decreased pubic hair, and a small penis. Because of their long legs, men with Klinefelter syndrome often are taller than predicted based on parental height. Body habitus may be feminized. In childhood, when there is a relative quiescence in the hormonal milieu, ascertainment of the syndrome may be difficult because the effects of hypogonadism (i.e., small external genitalia and firm testes) may be subtle or not present at all.

      Your Answer:

      Correct Answer: Inflammatory bowel disease

      Explanation:

      Answer: Inflammatory bowel diseaseThe inflammatory bowel diseases (IBDs), including ulcerative colitis and Crohn disease, are chronic inflammatory disorders of the gastrointestinal tract most often diagnosed in adolescence and young adulthood, with a rising incidence in paediatric populations. Inflammatory bowel disease is caused by a dysregulated mucosal immune response to the intestinal microflora in genetically predisposed hosts. Although children can present with the classic symptoms of weight loss, abdominal pain, and bloody diarrhoea, many present with nonclassical symptoms of isolated poor growth, anaemia, or other extraintestinal manifestations.Colorectal Carcinoma (CRC) is rare in patients less than 20 years of age.

      The adult height potential may be calculated for a male child by (father’s height in cm + mother’s height in cm) / 2 then add 7 cm.In the scenario provided: (170 + 150)/2 + 7 = 167 cm = 1.67 m.For a female child by (father’s height in cm + mother’s height in cm) / 2 then minus 7 cm.This can then be plotted on a height centile chart to find the mid-parental centile.Causes of short stature include:- Normal variant (often familial)- Constitutional delay of growth and puberty- Chronic illness, e.g. cystic fibrosis, inflammatory bowel disease- Endocrine: growth hormone deficiency, hypothyroidism, steroid excess syndromes: Turner’s, Down’s, Prader-Willi- Skeletal dysplasias, e.g. achondroplasia

    Incorrect

    • What are the chances of offspring developing cystic fibrosis if one of the parents, more specifically the mother, is suffering from the disease?

      Your Answer:

      Correct Answer: Depends on genetic makeup of partner

      Explanation:

      Cystic fibrosis has an autosomal recessive pattern of inheritance, meaning that a person might be a carrier of the disease without developing it. If the unaffected partner is a carrier, then there is a 50% chance of inheritance and another 50% chance of having a child who is a carrier. However, if the partner is not a carrier, the offspring will not develop the disease but the possibility of being a carrier raises up to 100%.
