An 8 year old boy was admitted following a MVA. His BMI is 28 kb/m2 and he's been found to have glycosuria, which resolved after his recovery. Which investigation is necessary to perform as part of the follow-up?
Your Answer: Glycosylated haemoglobin (HbA1c)
Correct Answer: Fasting blood glucose concentration
Explanation:The boy has an increased BMI which implies he is overweight. Possible trauma to his pancreas might have led to a diabetes-like condition, induced by damage to the beta cells. Fasting blood glucose should be measured as a follow-up strategy to see if the damage is reversible or irreversible and to conclude if the glycosuria is related to his metabolic profile or to his accident.

A 16-year-old schoolboy presents for a regular medical check-up. He complains of a red patch of skin on his chest, that is surrounded by an area of skin scaling. This was followed by the development of oval macules over the rest of his trunk, arms and thighs three days later. he has just returned to school for the start of Spring term. What is the most likely diagnosis?
Your Answer: Pityriasis rosea
Explanation:Pityriasis rosea is a common, acute exanthem of uncertain aetiology. Viral and bacterial causes have been sought, but convincing answers have not yet been found. Pityriasis rosea typically affects children and young adults. It is characterized by an initial herald patch, followed by the development of a diffuse papulosquamous rash. The herald patch often is misdiagnosed as eczema. Pityriasis rosea is difficult to identify until the appearance of characteristic smaller secondary lesions that follow Langer’s lines (cleavage lines). Several medications can cause a rash similar to pityriasis rosea, and several diseases, including secondary syphilis, are included in the differential diagnosis.

Angelman's syndrome is characterized by a gene deletion in which of the following chromosomes?
Your Answer: Chromosome 15
Explanation:Angelman Syndrome is a genetic disorder that affects the nervous system. The features of this condition include intellectual disability, a delay in developmental milestones, and movement disorders. The features occur as a result of the deletion or mutation of the maternal copy of the UBE3A gene located on Chromosome 15q. Though individuals usually inherit one copy of this gene from each parent, only the maternal gene remains active in parts of the brain. This phenomenon is known as genetic imprinting, and is also seen in Prader-Willi syndrome.

Which of the given medical conditions is associated with renal cysts and follows an autosomal dominant pattern of inheritance?
Your Answer: Von Hippel-Lindau syndrome
Explanation:Von Hippel-Lindau syndrome is a genetic disorder inherited in autosomal dominant fashion. It is caused by the mutations of the VHL gene located on chromosome 3. The syndrome is characterized by the creation of multiple benign and malignant tumours involving various bodily systems along with the formation of numerous visceral cysts, including the renal and epididymal cysts. Down’s syndrome is associated with renal cysts, but it does not follow the autosomal dominant mode of inheritance, rather it is caused by non-disjunction of chromosome 21 during meiosis. Exomphalos is a defect of the medial abdominal wall leading to abnormal protrusion of abdominal viscera through it. It is not associated with renal cysts. Turner’s syndrome may be associated with renal cysts formation, but it is not transmitted in an autosomal dominant fashion. Polycystic kidney disease of childhood follows an autosomal recessive pattern of transmission.

A 12-year old girl was brought to the hospital with recurrent headaches for 6 months. Her physical examination revealed no abnormality. A CT scan of the head revealed a suprasellar mass with calcifications, eroding the surrounding sella turcica. The lesion is likely to represent:
Your Answer: ACTH-secreting pituitary adenoma
Correct Answer: Craniopharyngioma
Explanation:Craniopharyngiomas (also known as Rathke pouch tumours, adamantinomas or hypophyseal duct tumours) affect children mainly between the age of 5 and 10 years. It constitutes 9% of brain tumours affecting the paediatric population. These are slow-growing tumours which can also be cystic, and arise from the pituitary stalk, specifically the nests of epithelium derived from Rathke’s pouch. Histologically, this tumour shows nests of squamous epithelium which is lined on the outside by radially arranged cells. Calcium deposition is often seen with a papillary type of architecture.ACTH-secreting pituitary adenomas are rare and mostly microadenomas. Paediatric astrocytoma’s usually occur in the posterior fossa. Although null cell adenomas can cause mass effect and give rise to the described symptoms, they are not suprasellar. Prolactinomas can also show symptoms of headache and disturbances in the visual field, however they are known to be small and slow-growing.

A 17-year-old female presents with pelvic pain occurring during her periods, with 'deep' pain during intercourse and pain on defecation during this time. She states that her periods are regular with little bleeding.What is the most likely diagnosis?
Your Answer: Endometriosis
Explanation:Endometriosis is defined as the presence of normal endometrial mucosa (glands and stroma) abnormally implanted in locations other than the uterine cavityAbout one third of women with endometriosis remain asymptomatic. When they do occur, symptoms, such as the following, typically reflect the area of involvement:- Dysmenorrhea- Heavy or irregular bleeding- Pelvic pain- Lower abdominal or back pain – Dyspareunia- Dyschezia (pain on defecation) – Often with cycles of diarrhoea and constipation- Bloating, nausea, and vomiting- Inguinal pain- Pain on micturition and/or urinary frequency- Pain during exercise- Patients with endometriosis do not frequently have any physical examination findings beyond tenderness related to the site of involvement. – The most common finding is nonspecific pelvic tenderness.

A 16-year-old boy presents with poor development of secondary sex characteristics, colour blindness and a decreased sense of smell. On examination, his testes are located in the scrotum and are small and soft. What is the most likely diagnosis for this boy?
Your Answer:
Correct Answer: Kallmann's syndrome
Explanation:Based on the clinical scenario, the most probable diagnosis in this patient is Kallmann’s syndrome.Kallmann’s syndrome is due to isolated gonadotrophin-releasing hormone (GnRH) deficiency. It is often inherited in an X-linked recessive manner. Other options:- While Klinefelter’s syndrome is also associated with hypogonadism, the other clinical features of Klinefelter’s are not seen. – Cryptorchidism is ruled out by the presence of testes in the scrotum. – The presentation of the child is not suggestive of mumps orchitis or hyperprolactinaemia.

A new-born baby has a loud murmur, grade 3/6, at the upper left sternal edge. Which one of the following statements about examination techniques is correct?
Your Answer:
Correct Answer: Feeling femoral pulses is mandatory
Explanation:Heart murmurs are common in healthy infants, children, and adolescents. Although most are not pathologic, a murmur may be the sole manifestation of serious heart disease. Historical elements that suggest pathology include family history of sudden cardiac death or congenital heart disease, in utero exposure to certain medications or alcohol, maternal diabetes mellitus, history of rheumatic fever or Kawasaki disease, and certain genetic disorders. Physical examination should focus on vital signs; age-appropriate exercise capacity; respiratory or gastrointestinal manifestations of congestive heart failure; and a thorough cardiovascular examination, including features of the murmur, assessment of peripheral perfusion, and auscultation over the heart valves. Red flags that increase the likelihood of a pathologic murmur include a holosystolic or diastolic murmur, grade 3 or higher murmur, harsh quality, an abnormal S2, maximal murmur intensity at the upper left sternal border, a systolic click, or increased intensity when the patient stands. Electrocardiography and chest radiography rarely assist in the diagnosis.

What is the first sign of puberty in girls?
Your Answer:
Correct Answer: Breast development
Explanation:The average age for girls to begin puberty is 11.The first sign of puberty in girls is usually that their breasts begin to develop.It’s normal for breast buds to sometimes be very tender or for one breast to start to develop several months before the other one.Pubic hair also starts to grow, and some girls may notice more hair on their legs and arms.After a year or so of puberty beginning, and for the next couple of years:girls’ breasts continue to grow and become fuller.Around 2 years after beginning puberty, girls usually have their first period,pubic hair becomes coarser and curlierunderarm hair begins to grow. From the time their periods start, girls grow 5 to 7.5cm (2 to 3 inches) annually over the next year or two, then reach their adult height.After about 4 years of puberty in girls:breasts become adult-likepubic hair has spread to the inner thighgenitals should now be fully developedgirls stop growing taller.

A 13-year-old girl was recently diagnosed with type 1 diabetes mellitus about two weeks ago and started on an insulin pump. Which of the following complications is least likely to occur due to the treatment modality adopted?
Your Answer:
Correct Answer: Lipoatrophy
Explanation:Among the given options, lipoatrophy takes time to develop as it is a long-term complication of insulin therapy. Since it has only been two weeks since the initiation of insulin therapy, it is unlikely to occur so early.The risk of lipoatrophy is reduced with newer insulins and also can be avoided by site rotation.However, anaphylaxis, allergic reactions, infection and abscesses at the site of an insulin pump can occur in this patient as a complication of insulin therapy.

An 8 year old boy is admitted to the ward with renal colic. Family history is significant for similar renal calculi in his mother. Which of the following is the most likely explanation for this recurrent colic in both mother and child?
Your Answer:
Correct Answer: Idiopathic hypercalciuria
Explanation:Idiopathic hypercalciuria (IH) is the commonest metabolic abnormality in patients with calcium kidney stones. It is characterized by normocalcemia, absence of diseases that cause increased urine calcium, and calcium excretion that is above 250 mg/day in women and 300 mg/day in men. Subjects with IH have a generalized increase in calcium turnover, which includes increased gut calcium absorption, decreased renal calcium reabsorption, and a tendency to lose calcium from bone. Despite the increase in intestinal calcium absorption, negative calcium balance is commonly seen in balance studies, especially on a low calcium diet. The mediator of decreased renal calcium reabsorption is not clear; it is not associated with either an increase in filtered load of calcium or altered PTH levels. There is an increased incidence of hypercalciuria in first-degree relatives of those with IH, but IH appears to be a complex polygenic trait with a large contribution from diet to expression of increased calcium excretion. Increased tissue vitamin D response may be responsible for the manifestations of IH in at least some patients.

Which is not true relating to growth in the normal child?
Your Answer:
Correct Answer: Full growth hormone responsiveness develops in puberty
Explanation:Most healthy infants and children grow predictably, following a typical pattern of progression in weight, length, and head circumference. Normal human growth is pulsatile; periods of rapid growth (growth spurts) are separated by periods of no measurable growth Growth hormone levels and responsiveness’ develop in late infancy, increase during childhood and peak during puberty.Typical milestones – General guidelines regarding length or height gain during infancy and childhood include the following:- The average length at birth for a term infant is 20 inches (50 cm)- Infants grow 10 inches (25 cm) during the first year of life- Toddlers grow 4 inches (10 cm) between 12 and 24 months, 3 inches (7.5 cm) between 24 and 36 months, and 3 inches (7.5 cm) between 36 and 48 months- Children reach one-half of their adult height by 24 to 30 months- Children grow 2 inches per year (5 cm per year) between age four years and puberty- There is a normal deceleration of height velocity before the pubertal growth spurt.Growth continues past pubertal growth spurt as there is increase in spinal length.

What is the main mechanism of action of the combined oral contraceptive pill?
Your Answer:
Correct Answer: Inhibition of ovulation
Explanation:The progesterone is primarily responsible for preventing pregnancy. The main mechanism of action is the prevention of ovulation; they inhibit follicular development and prevent ovulation. Progestogen negative feedback works at the hypothalamus to decreases the pulse frequency of gonadotropin-releasing hormone. This, in turn, will decrease the secretion of follicle-stimulating hormone (FSH) and decreases the secretion of luteinizing hormone (LH). If the follicle isn’t developing, then there is no increase in the oestradiol levels (the follicle makes oestradiol). The progestogen negative feedback and lack of oestrogen positive feedback on LH secretion stop the mid-cycle LH surge. With no follicle developed and no LH surge to release the follicle, there is the prevention of ovulation. Oestrogen has some effect with inhibiting follicular development because of its negative feedback on the anterior pituitary with slows FSH secretion; it’s just not as prominent as the progesterone’s effect. Another primary mechanism of action is progesterone’s ability to inhibit sperm from penetrating through the cervix and upper genital tract by making the cervical mucous unfriendly. Progesterone induced endometrial atrophy should deter implantation, but there is no proof that this occurs.

A 14-year-old girl presents with short stature, webbed neck and primary amenorrhoea.Given the likely clinical diagnosis, which hormone replacement is most crucial over the longer term?
Your Answer:
Correct Answer: Oestrogen
Explanation:This girl most likely has Turner syndrome (TS) also known as 45,X, a condition in which a female is partly or completely missing an X chromosome. Signs and symptoms vary among those affected. Often, a short and webbed neck, low-set ears, low hairline at the back of the neck, short stature, and swollen hands and feet are seen at birth. Typically, they are without menstrual periods, do not develop breasts, and are unable to have children. Heart defects, diabetes, and low thyroid hormone occur more frequently. Most people with TS have normal intelligence. Many, however, have troubles with spatial visualization such as that needed for mathematics. Vision and hearing problems occur more often. Turner syndrome is not usually inherited from a person’s parents. No environmental risks are known and the mother’s age does not play a role. As a chromosomal condition, there is no cure for Turner syndrome. However, much can be done to minimize the symptoms including prescribing growth hormone, either alone or with a low dose of androgen, and oestrogen replacement therapy which is crucial long term for maintaining good bone integrity, cardiovascular health and tissue health

Which of the following types best describe the epithelium on the external aspect of the tympanic membrane?
Your Answer:
Correct Answer: Stratified squamous
Explanation:The external aspect of the tympanic membrane is lined by stratified squamous epithelium. Clinical correlation: Following middle ear infections, this type of epithelium can migrate into the middle ear through a perforated tympanic membrane.The ear is composed of three anatomically distinct regions: – External ear: Auricle is composed of elastic cartilage covered by skin. The lobule has no cartilage and contains fat and fibrous tissue. External auditory meatus is variable in length, measuring approximately 2.5cm long in fully grown children. Lateral third of the external auditory meatus is cartilaginous, and the medial two-thirds is bony. The greater auricular nerve innervates the region. The auriculotemporal branch of the trigeminal nerve supplies most of the external auditory meatus and the lateral surface of the auricle. – Middle ear: It is the space between the tympanic membrane and cochlea. The aditus leads to the mastoid air cells is the route through which middle ear infections may cause mastoiditis. Anteriorly the eustachian tube connects the middle ear to the nasopharynx. The tympanic membrane consists of an outer layer of stratified squamous epithelium, a middle layer of fibrous tissue and an inner layer of mucous membrane continuous with the middle ear. The chorda tympani nerve passes on the medial side of the pars flaccida. The glossopharyngeal nerve and pain innervate the middle ear. Thus, pain may radiate to the middle ear following tonsillectomy. – Ossicles:Malleus attaches to the tympanic membrane (the Umbo). Malleus articulates with the incus (synovial joint). Incus attaches to stapes (another synovial joint). – Internal ear:It consists of the cochlea, semicircular canals, and vestibule. Organ of Corti is the sense organ of hearing and is located on the inside of the cochlear duct on the basilar membrane. Vestibule accommodates the utricle and the saccule. These structures contain endolymph and are surrounded by perilymph within the vestibule. The semicircular canals lie at various angles to the petrous temporal bone. All share a common opening into the vestibule.

A new-born term baby has a 2/6 systolic murmur 6-hours after delivery.Which one of the following is the most common explanation of this murmur?
Your Answer:
Correct Answer: Tricuspid regurgitation
Explanation:The murmur of tricuspid valve regurgitation is typically a high-pitched, blowing, holosystolic, plateau, nonradiating murmur best heard at the lower left sternal border. The intensity is variable, but tends to increase during inspiration (Carvallo’s sign), with passive leg raising, after a post-extrasystole pause, and following amyl nitrite inhalation. The intensity of the murmur tends to correlate positively with the severity of regurgitation. Right ventricular enlargement may displace the location of the murmur leftward. Right ventricular failure may abolish respiratory variation. When tricuspid regurgitation is caused by pulmonary hypertension, a pulmonic ejection click may be audible. Severe tricuspid regurgitation is commonly accompanied by a third heart sound emanating from the right ventricle and best heard at the lower left sternal border. Severe tricuspid regurgitation typically produces an accentuated jugular cv wave and may produce hepatic congestion with a pulsatile liver.The auscultatory findings associated with ventricular septal defect are variable, depending on a variety of morphologic and hemodynamic considerations. The systolic murmur associated with a Roger’s-type ventricular septal defect (regurgitant jet flows directly into the right ventricular outflow tract) in patients with low pulmonary vascular resistance is a low to medium pitched, holosystolic murmur with midsystolic accentuation. The intensity of the murmur is typically grade 3 or higher.Patent ductus arteriosus produces a continuous murmur in patients with normal pulmonary vascular resistance.

A male infant is brought to the emergency department by his parents. He was born at 34 weeks by spontaneous vaginal delivery and was discharged 4 weeks ago. He is not on any regular medication. Parents said that he brings up small volumes of milk after feeds. This happens approximately twice a day. Observations are all within normal range and examination is unremarkable.Which of the following is the most likely diagnosis?
Your Answer:
Correct Answer: Gastro-oesophageal reflux
Explanation:Gastroesophageal reflux occurs in almost all infants, manifesting as wet burps after feeding. The spit-ups appear effortless and not particularly forceful.Infants in whom reflux has caused GERD have additional symptoms, such as irritability, feeding refusal, and/or respiratory symptoms such as chronic recurrent coughing or wheezing and sometimes stridor. Much less commonly, infants have intermittent apnoea or episodes of arching the back and turning the head to one side (Sandifer syndrome). Infants may fail to gain weight appropriately or, less often, lose weight.Incidence of gastroesophageal reflux increases between 2 months and 6 months of age (likely due to an increased volume of liquid at each feeding) and then starts to decrease after 7 months. Gastroesophageal reflux resolves in about 85% of infants by 12 months and in 95% by 18 months.

A 14-month-old boy is brought to the paediatric clinic by his mother with complaints of vomiting, abdominal pain, and rectal bleeding. On examination, he is found to be dehydrated, and a palpable abdominal mass was felt. A Meckel's scan proved to be negative. However, the ultrasound scan did reveal a target sign.What is the most probable cause of the patient's complaints?
Your Answer:
Correct Answer: Intussusception
Explanation:The most probable cause for the patient’s symptoms is intussusception.Intussusception is a condition in which part of the intestine folds into the section next to it. It most commonly involves the small bowel and rarely the large bowel. Intussusception doesn’t usually require surgical correction. 80% of cases can be both confirmed and reduced using barium, water-soluble or air-contrast enema. However, up to 10% of cases can experience recurrence within 24 hours after reduction, warranting close monitoring during this period.Other options:- Enteric duplication: a duplication cyst could give all these features, although it may contain sufficient gastric epithelium to produce a positive Meckel’s scan. However, this is comparatively rare. – Meckel’s diverticulum: Scintigraphy has poor sensitivity making the possibility of a bleed from a Meckel’s diverticulum a genuine differential for this patient. However, considering the presence of features of bowel obstruction in the patient, a Meckel’s diverticulum bleeding and obstructing at the same time would be a rare phenomenon. – Midgut volvulus: It is also a plausible differential in this patient. However, for the given age group, a midgut volvulus is relatively uncommon compared to intussusception. – Acute appendicitis: While it is true that appendicitis can present acutely with a palpable mass and bowel obstruction, it rarely presents with rectal bleeding.

A 15-year-old boy presents with poor development of secondary sex characteristics, colour blindness and a decreased sense of smell. On examination, his testes are small soft and located in the scrotum.What is the most probable diagnosis?
Your Answer:
Correct Answer: Kallmann's syndrome
Explanation:Classic Kallmann syndrome (KS) is due to isolated hypogonadotropic hypogonadism. Most patients have gonadotropin-releasing hormone (GnRH) deficiency, as suggested by their response to pulsatile GnRH therapy. The hypothalamic-pituitary function is otherwise normal in most patients, and hypothalamic-pituitary imaging reveals no space-occupying lesions. By definition, either anosmia or severe hyposmia is present in patients with Kallmann syndrome.

Your Answer:
Correct Answer: Cholesterol crystals
Explanation:Due to breakdown of the red blood cell membrane in haemophilic patients, cholesterol crystals are formed by the lipids. On the other hand lipofuscin deposition does not occur in haemolysis or haemorrhage. Neutrophil accumulation suggests acute inflammation. Anthracotic pigment is an exogenous carbon pigment that deposits in the lung from dust. Russell bodies are intracellular accumulations of immunoglobins in plasma cells.
