Question 1
Correct
-
The mother of a 3-year-old child is worried about her child's developmental progress. Upon assessment, you observe that the child can only build a tower of five blocks at most and can only speak in two to three-word phrases. What is the typical age range for a healthy child to achieve these developmental milestones?
Your Answer: 2 ½ years
Explanation:Developmental Delay in Children
Developmental delay in children can be a cause for concern, especially when they fail to meet certain milestones at their age. For instance, a 4-year-old child should be able to speak in full sentences, play interactively, and build structures with building blocks. However, when a child exhibits a degree of developmental delay, it could be due to various factors such as neurological and neurodevelopmental problems like cerebral palsy and epilepsy, unmet physical and psychological needs, sensory impairment, genetic conditions like Down’s syndrome, and ill health.
It is important to understand the causes of developmental delay in children to provide appropriate interventions and support. Parents and caregivers should observe their child’s development and seek professional help if they notice any delays or abnormalities. Early intervention can help address developmental delays and improve a child’s overall well-being. By the factors that contribute to developmental delay, we can work towards creating a supportive environment that promotes healthy growth and development in children.

Question 2
Incorrect

A 4-year-old girl is brought to the pediatrician by her mother. The mother is concerned as she has noticed some hair growing in her daughter's armpits, and although she has not shown any distress or had any other noticeable symptoms, the mother is worried that something is wrong as she is too young to begin going through puberty. On examination, the child has axillary hair growth bilaterally, and her breasts are of appropriate size for her age.
Gonadotrophin assays show the following:
FSH 0.2 IU/L Age 6 months - 10 years old: (1 - 3)
LH 0.1 IU/L Age 6 months - 10 years old: (1 - 5)
What is the most likely cause of this child's axillary hair growth?Your Answer:
Correct Answer: Adrenal hyperplasia
Explanation:In cases of gonadotrophin independent precocious puberty (GIPP), both FSH and LH levels are low. This is in contrast to gonadotrophin dependent precocious puberty (GDPP), where FSH and LH levels are high and testes are larger than expected for age. GIPP is caused by increased levels of sex hormones, such as testosterone, which suppress LH and FSH. This can be due to ovarian, testicular, or adrenal causes, such as congenital adrenal hyperplasia. In boys with GIPP, testicular volume is typically normal or small. Adrenal hyperplasia is the only cause of GIPP, as all other causes would result in GDPP and increased levels of FSH and LH.
Understanding Precocious Puberty
Precocious puberty is a condition where secondary sexual characteristics develop earlier than expected, before the age of 8 in females and 9 in males. It is more common in females and can be classified into two types: gonadotrophin dependent and gonadotrophin independent. The former is caused by premature activation of the hypothalamic-pituitary-gonadal axis, resulting in raised levels of FSH and LH. The latter is caused by excess sex hormones, with low levels of FSH and LH. In males, precocious puberty is uncommon and usually has an organic cause, such as gonadotrophin release from an intracranial lesion, gonadal tumour, or adrenal cause. In females, it is usually idiopathic or familial and follows the normal sequence of puberty. Organic causes are rare and associated with rapid onset, neurological symptoms and signs, and dissonance, such as in McCune Albright syndrome. Understanding precocious puberty is important for early detection and management of the condition.

A 6-week-old girl is brought to the hospital and placed under the care of the paediatric surgeons due to her parents' concern about her symptoms. She has been experiencing projectile vomiting, weight loss, and constant hunger. The doctors have made a preliminary diagnosis of pyloric stenosis. What is the probable biochemical abnormality associated with this condition?
Your Answer:
Correct Answer: Hypokalaemic hypochloraemic alkalosis
Explanation:Pyloric Stenosis: Characteristics and Biochemical Abnormalities
Pyloric stenosis is a condition commonly observed in male infants at around 5 weeks old, with an incidence rate of approximately 4 per 1000. It is often seen in first-born babies. The condition is characterized by the narrowing of the pylorus, the opening between the stomach and the small intestine, which causes difficulty in food passage.
One of the typical biochemical abnormalities observed in patients with pyloric stenosis is hypokalaemic hypochloraemic alkalosis, which is caused by the loss of hydrogen and chloride ions in the vomit. This results in an acidic urine. The imbalance of electrolytes in the body can lead to dehydration, weakness, and other complications. Early diagnosis and treatment are crucial to prevent further health problems.

Which condition is commonly associated with neonatal cyanosis?
Your Answer:
Correct Answer: Total anomalous pulmonary venous drainage
Explanation:Total Anomalous Pulmonary Venous Connection
Total anomalous pulmonary venous connection (TAPVC) is a condition that causes cyanosis in newborns. It is characterized by an abnormality in blood flow where all four pulmonary veins drain into systemic veins or the right atrium, with or without pulmonary venous obstruction. This results in the mixing of systemic and pulmonary venous blood in the right atrium.
In contrast, conditions such as patent ductus arteriosus (PDA), atrial septal defect (ASD), and ventricular septal defect (VSD) are left to right shunts. Tricuspid atresia is another condition that is typically associated with cyanosis, but mitral regurgitation is not.
It is important to understand the differences between these conditions and their effects on blood flow in order to properly diagnose and treat them. Further reading on TAPVC can be found on Medscape.

A 12-year-old boy comes to see his GP complaining of hip and knee pain on one side. He reports that the pain started 2 weeks ago after he was tackled while playing football. His limp has become more pronounced recently. During the examination, the doctor notes a reduced ability to internally rotate the leg when flexed. The boy has no fever and his vital signs are stable. What is the probable diagnosis?
Your Answer:
Correct Answer: Slipped capital femoral epiphysis
Explanation:Slipped capital femoral epiphysis is often associated with a loss of internal rotation of the leg in flexion. Acute transient synovitis is an incorrect answer as it typically resolves within 1-2 weeks and is often preceded by an upper respiratory infection. Developmental dysplasia of the hip is typically diagnosed in younger children and can be detected using the Barlow and Ortolani tests. While Perthes’ disease is a possibility, the loss of internal rotation of the leg in flexion makes slipped capital femoral epiphysis a more likely diagnosis. Septic arthritis would present with a fever and may result in difficulty bearing weight.
Slipped Capital Femoral Epiphysis: A Rare Hip Condition in Children
Slipped capital femoral epiphysis, also known as slipped upper femoral epiphysis, is a rare hip condition that primarily affects children between the ages of 10 and 15. It is more commonly seen in obese boys. This condition is characterized by the displacement of the femoral head epiphysis postero-inferiorly, which may present acutely following trauma or with chronic, persistent symptoms.
The most common symptoms of slipped capital femoral epiphysis include hip, groin, medial thigh, or knee pain and loss of internal rotation of the leg in flexion. In some cases, a bilateral slip may occur. Diagnostic imaging, such as AP and lateral (typically frog-leg) views, can confirm the diagnosis.
The management of slipped capital femoral epiphysis typically involves internal fixation, which involves placing a single cannulated screw in the center of the epiphysis. However, if left untreated, this condition can lead to complications such as osteoarthritis, avascular necrosis of the femoral head, chondrolysis, and leg length discrepancy.
In summary, slipped capital femoral epiphysis is a rare hip condition that primarily affects children, especially obese boys. It is characterized by the displacement of the femoral head epiphysis postero-inferiorly and can present with various symptoms. Early diagnosis and management are crucial to prevent complications.

A 6-year-old boy arrives at the Emergency Department with a high fever, difficulty breathing, severe sore throat, and drooling of saliva. What is the best course of action for management?
Your Answer:
Correct Answer: Call the ear, nose and throat (ENT) surgeon/senior anaesthetist to secure her airway
Explanation:Managing Acute Epiglottitis: Prioritizing Airway Security
Acute epiglottitis is a medical emergency that requires immediate attention to secure the patient’s airway. While medical therapies and investigations are important, the priority should be given to securing the airway via endo-/nasotracheal intubation or tracheostomy guided by a senior anaesthetist and ENT surgeon. Oral instrumentation is contraindicated until the airway has been secured. Lateral neck X-ray may be useful in diagnosing less acute presentations, but in this case, the child requires intravenous broad-spectrum antibiotics and admission to an Intensive Therapy Unit/High-dependency Unit bed in the hospital. Intubating a child with acute epiglottitis can be challenging and should only be undertaken by an experienced anaesthetist.

During the baby check of Maya, a 4-day-old neonate delivered via Caesarean section due to a breech position, both Barlows and Ortolani's tests are negative. What should be the next best step?
Your Answer:
Correct Answer: Perform a bilateral hip ultrasound at 4-6 weeks
Explanation:The Importance of Bilateral Hip Ultrasound in Newborns with Risk Factors for Developmental Dysplasia of the Hip
Babies with risk factors for developmental dysplasia of the hip require further investigation even if they test negative on Barlows and Ortolani’s tests. National guidelines recommend a bilateral hip ultrasound at 4-6 weeks for these infants. If the Barlow’s or Ortolani’s tests are abnormal, a scan should be done within 2 weeks. In cases where the baby was in the breech position at term but had negative test results, a hip ultrasound is still necessary. It is important to reassure parents that this is a normal procedure and that no treatment may be necessary. Bilateral hip radiographs are not useful in neonates and MRI is not used in the diagnosis of developmental dysplasia of the hip. Operative approaches are only recommended for patients over 18 months of age, and conservative approaches are preferred for younger children.

A 5-year-old boy is seen in an acute paediatric clinic due to unexplained bruising and hepatosplenomegaly on examination. He has a past medical history of Down's syndrome and was placed in foster care immediately after birth. His birth mother, who was 45 years old at delivery, smoked during pregnancy and has a history of osteosarcoma. After further investigations, including a full blood count and bone marrow aspirate, the diagnosis of acute lymphocytic leukaemia is suspected. What is the most significant risk factor associated with this condition?
Your Answer:
Correct Answer: History of Down's syndrome
Explanation:Children with Down syndrome are at a higher risk of developing acute lymphoblastic leukaemia due to the loss of a gene that inhibits lymphocyte proliferation known as PCR2. This risk is over 30 times higher than in children without Down syndrome. Additionally, children with Down syndrome are over 100 times more likely to develop acute myeloid leukaemia. Family history of malignancy, maternal age, and female sex are not significant risk factors for the development of ALL.
Down’s syndrome is a genetic disorder that is characterized by various clinical features. These features include an upslanting of the palpebral fissures, epicanthic folds, Brushfield spots in the iris, a protruding tongue, small low-set ears, and a round or flat face. Additionally, individuals with Down’s syndrome may have a flat occiput, a single palmar crease, and a pronounced sandal gap between their big and first toe. Hypotonia, congenital heart defects, duodenal atresia, and Hirschsprung’s disease are also common in individuals with Down’s syndrome.
Cardiac complications are also prevalent in individuals with Down’s syndrome, with multiple cardiac problems potentially present. The most common cardiac defect is the endocardial cushion defect, also known as atrioventricular septal canal defects, which affects 40% of individuals with Down’s syndrome. Other cardiac defects include ventricular septal defect, secundum atrial septal defect, tetralogy of Fallot, and isolated patent ductus arteriosus.
Later complications of Down’s syndrome include subfertility, learning difficulties, short stature, repeated respiratory infections, hearing impairment from glue ear, acute lymphoblastic leukaemia, hypothyroidism, Alzheimer’s disease, and atlantoaxial instability. Males with Down’s syndrome are almost always infertile due to impaired spermatogenesis, while females are usually subfertile and have an increased incidence of problems with pregnancy and labour.

A 7-year-old girl is brought to the Emergency Department (ED) by her parents due to a painful knee. The knee is swollen, red, hot, and tender. The patient experiences extreme pain when the joint is moved, and resists any attempts to flex it passively. Upon examination, you notice a cut on the affected knee, which the parents explain was caused by a fall on the playground. The patient has a mild fever but is otherwise healthy, without other areas of pain or additional joint involvement.
What is the most probable diagnosis?Your Answer:
Correct Answer: Septic arthritis
Explanation:Differential Diagnosis for a Patient with Knee Pain and Inflammation
Upon examination of a patient with knee pain and inflammation, several differential diagnoses should be considered. Septic arthritis is a likely possibility, especially if the patient has a recent cut or injury that could have allowed infective organisms to enter the joint. Non-accidental injury (NAI) should also be considered, although in this case, it is unlikely given the patient’s age, single injury, and relevant history. Slipped upper femoral epiphysis (SUFE), Osgood–Schlatter’s disease, and patellofemoral pain syndrome are less likely possibilities, as they typically present with different symptoms than what is observed in this patient. Overall, a thorough examination and consideration of all possible diagnoses is necessary to accurately diagnose and treat knee pain and inflammation.

You are an FY1 on the neonatal ward round with your consultant. Whilst seeing a newborn that has been admitted with respiratory distress, the consultant you're with decides to quiz you on the pathophysiology.
'What is the most likely organism to cause respiratory distress syndrome in premature infants?Your Answer:
Correct Answer: Parainfluenza virus
Explanation:The majority of croup cases are caused by the parainfluenza virus, while bronchiolitis is commonly caused by RSV. Pseudomonas aeruginosa is associated with pseudomonas, and Streptococcus pneumoniae is a common cause of pneumonia.
Understanding Croup: A Respiratory Infection in Infants and Toddlers
Croup is a type of upper respiratory tract infection that commonly affects infants and toddlers. It is characterized by a barking cough, fever, and coryzal symptoms, and is caused by a combination of laryngeal oedema and secretions. Parainfluenza viruses are the most common cause of croup. The condition typically peaks between 6 months and 3 years of age, and is more prevalent during the autumn season.
The severity of croup can be graded based on the presence of symptoms such as stridor, cough, and respiratory distress. Mild cases may only have occasional barking cough and no audible stridor at rest, while severe cases may have frequent barking cough, prominent inspiratory stridor at rest, and marked sternal wall retractions. Children with moderate or severe croup, those under 6 months of age, or those with known upper airway abnormalities should be admitted to the hospital.
Diagnosis of croup is usually made based on clinical presentation, but a chest x-ray may show subglottic narrowing, commonly referred to as the steeple sign. Treatment for croup typically involves a single dose of oral dexamethasone or prednisolone, regardless of severity. In emergency situations, high-flow oxygen and nebulized adrenaline may be necessary.
Understanding croup is important for parents and healthcare providers alike, as prompt recognition and treatment can help prevent complications and improve outcomes for affected children.

A 4-month-old boy is being seen by his GP for an undescended testi. During the NIPE at birth, his right testi was found to be undescended. On examination today, only one testi is palpated in the scrotum. The patient is referred to the surgeons for further evaluation. What potential complication is this patient at an elevated risk of experiencing if the undescended testi is not addressed?
Your Answer:
Correct Answer: Testicular torsion
Explanation:Undescended testicles can lead to testicular torsion, infertility, and testicular cancer if left untreated. It is recommended to wait up to three months for spontaneous descent, but intervention should occur by six months of age. Femoral hernias are rare in childhood, but undescended testicles may increase the risk of an inguinal hernia. Hydroceles are common at birth and resolve on their own, without known association to undescended testicles. While orchitis can occur in an undescended testis, there is no increased risk of orchitis due to lack of descent.
Undescended Testis: Causes, Complications, and Management
Undescended testis is a condition that affects around 2-3% of male infants born at term, but it is more common in preterm babies. Bilateral undescended testes occur in about 25% of cases. This condition can lead to complications such as infertility, torsion, testicular cancer, and psychological issues.
To manage unilateral undescended testis, NICE CKS recommends considering referral from around 3 months of age, with the baby ideally seeing a urological surgeon before 6 months of age. Orchidopexy, a surgical procedure, is typically performed at around 1 year of age, although surgical practices may vary.
For bilateral undescended testes, it is crucial to have the child reviewed by a senior paediatrician within 24 hours as they may require urgent endocrine or genetic investigation. Proper management of undescended testis is essential to prevent complications and ensure the child’s overall health and well-being.

A 4-week old infant comes in with excessive vomiting and constipation. The mother reports that the baby has vomited several times, but has been content during feedings. The baby appears visibly dehydrated and a small lump is detected in the abdominal area during examination. What arterial blood gas results would you anticipate?
Your Answer:
Correct Answer: Elevated bicarbonate, hypochloraemia, hypokalaemia
Explanation:The typical result of pyloric stenosis is the development of alkalosis with low levels of chloride and potassium.
Understanding Pyloric Stenosis
Pyloric stenosis is a condition that usually occurs in infants between the second and fourth weeks of life. However, in rare cases, it may present later, up to four months. This condition is caused by the thickening of the circular muscles of the pylorus. Pyloric stenosis is more common in males, with an incidence of 4 per 1,000 live births. It is also more likely to affect first-borns and infants with a positive family history.
The most common symptom of pyloric stenosis is projectile vomiting, which usually occurs about 30 minutes after a feed. Other symptoms may include constipation, dehydration, and a palpable mass in the upper abdomen. Prolonged vomiting can lead to hypochloraemic, hypokalaemic alkalosis, which can be life-threatening.
Diagnosis of pyloric stenosis is typically made using ultrasound. Management of this condition involves a surgical procedure called Ramstedt pyloromyotomy. This procedure involves making a small incision in the pylorus to relieve the obstruction and allow for normal passage of food. With prompt diagnosis and treatment, infants with pyloric stenosis can make a full recovery.

A 4-week-old girl is brought to the paediatric emergency department with a fever, vomiting and reduced appetite for the past 48 hours. The baby's growth and development have been normal so far. During the examination, the baby appears lethargic and fussy, with a respiratory rate that is faster than normal and a temperature of 39ºC. Blood pressure and pulse rate are within the normal range, and there are no signs of raised intracranial pressure. The medical team suspects bacterial meningitis and performs a lumbar puncture. What should be done while waiting for the lumbar puncture results?
Your Answer:
Correct Answer: Start empirical antibiotics only
Explanation:It is not recommended to use corticosteroids in children under 3 months of age who have suspected or confirmed bacterial meningitis. The most common organisms causing bacterial meningitis vary depending on the age of the child. For neonates up to 3 months old, Group B streptococcus, E.coli, and Listeria monocytogenes are the most common. For children between 1 month and 6 years old, Neisseria meningitidis, Streptococcus pneumoniae, and Haemophilus influenzae are the most common. For children over 6 years old, Neisseria meningitidis and Streptococcus pneumoniae are the most common. In older children with bacterial meningitis, dexamethasone may reduce the risk of hearing loss, particularly in those with Hib meningitis. However, it should be avoided in children under 3 months old with suspected or confirmed bacterial meningitis, as well as those with certain central nervous system abnormalities or nonbacterial meningitis. Activated protein C and recombinant bacterial permeability-increasing protein should not be used in children and young people with meningococcal septicaemia. Treatment should not be delayed for a CT scan, as bacterial meningitis is a medical emergency. Intravenous immunoglobulins are not currently recommended for the management of meningitis.
Investigation and Management of Meningitis in Children
Meningitis is a serious condition that can affect children. When investigating meningitis, it is important to note any contraindications to lumbar puncture, such as signs of raised intracranial pressure, focal neurological signs, papilloedema, significant bulging of the fontanelle, disseminated intravascular coagulation, or signs of cerebral herniation. For patients with meningococcal septicaemia, a lumbar puncture is contraindicated, and blood cultures and PCR for meningococcal should be obtained instead.
The management of meningitis in children involves administering antibiotics, such as IV amoxicillin (or ampicillin) and IV cefotaxime for children under three months, and IV cefotaxime (or ceftriaxone) for children over three months. Steroids should be considered if the lumbar puncture reveals certain findings, such as purulent cerebrospinal fluid, a high white blood cell count, or bacteria on Gram stain. Fluids should be administered to treat shock, and cerebral monitoring should be conducted, including mechanical ventilation if necessary.
It is also important to notify public health authorities and administer antibiotic prophylaxis to contacts. Ciprofloxacin is now preferred over rifampicin for this purpose. Overall, prompt and appropriate management of meningitis in children is crucial for ensuring the best possible outcomes.

A 2-week-old infant is presented with vomiting, feeding intolerance, and abdominal distension. During examination, it is observed that the nappy contains watery stools with specks of blood. An abdominal X-ray is performed, which shows gas cysts in the bowel wall. What is the probable diagnosis?
Your Answer:
Correct Answer: Necrotizing enterocolitis
Explanation:The most likely diagnosis is necrotizing enterocolitis based on the symptoms and the presence of gas cysts in the bowel wall on the abdominal x-ray. While Intussusception can also cause vomiting and abdominal distention, it is typically characterized by rectal bleeding that resembles red currant jelly. Additionally, Intussusception is more common in infants between 3-12 months of age, making it unlikely in a 1-week-old infant. An abdominal x-ray in Intussusception would show intestinal obstruction rather than gas cysts.
Understanding Necrotising Enterocolitis
Necrotising enterocolitis is a serious condition that is responsible for a significant number of premature infant deaths. The condition is characterized by symptoms such as feeding intolerance, abdominal distension, and bloody stools. If left untreated, these symptoms can quickly progress to more severe symptoms such as abdominal discolouration, perforation, and peritonitis.
To diagnose necrotising enterocolitis, doctors often use abdominal x-rays. These x-rays can reveal a number of important indicators of the condition, including dilated bowel loops, bowel wall oedema, and intramural gas. Other signs that may be visible on an x-ray include portal venous gas, pneumoperitoneum resulting from perforation, and air both inside and outside of the bowel wall. In some cases, an x-ray may also reveal air outlining the falciform ligament, which is known as the football sign.
Overall, understanding the symptoms and diagnostic indicators of necrotising enterocolitis is crucial for early detection and treatment of this serious condition. By working closely with healthcare professionals and following recommended screening protocols, parents and caregivers can help ensure the best possible outcomes for premature infants at risk for this condition.

A 4-year-old boy visits his pediatrician complaining of a new rash that has spread all over his body. Upon further inquiry, it is discovered that he had been experiencing a high fever, fatigue, conjunctivitis, and a mild cough for the past four days. During the last week, he had been experiencing these symptoms. Upon examination, the pediatrician notices small white spots on the inside of the boy's cheeks. What is the probable diagnosis?
Your Answer:
Correct Answer: Measles
Explanation:Symptoms of Measles
The initial symptoms of measles, known as the prodrome, include a high fever, cough, malaise, conjunctivitis, and coryza. Additionally, the buccal mucosa may develop white punctate lesions, which are referred to as Koplik spots. As the maculopapular cutaneous rash begins to appear, these spots fade away. The rash typically starts on the face and upper neck before spreading to the extremities. These symptoms are considered pathognomonic for measles, and the Koplik spots often disappear as the macular rash becomes more prominent. Overall, recognizing these symptoms is crucial for early diagnosis and treatment of measles.

The mother reports that the child has not been eating well for the past day and has been running a low-grade temperature. Additionally, the mother points out a partial thickness burn on the child's arm that has been treated with dressings by their GP. What is the probable diagnosis?
Your Answer:
Correct Answer: Toxic shock syndrome
Explanation:Differential diagnosis for an unwell child with an unhealed burn
When a child with an unhealed burn appears acutely unwell, several life-threatening conditions must be considered and ruled out promptly. Among them, toxic shock syndrome and meningococcal septicaemia are particularly concerning and require urgent management in the intensive care unit. Anaphylaxis, although a rare possibility, should also be considered and treated promptly with intramuscular adrenaline. Haemophilus influenzae and Salmonella are less likely causes, as they typically present with respiratory or gastrointestinal symptoms, respectively, which are not evident in this case. A thorough assessment and appropriate interventions are crucial to ensure the best possible outcome for the child.

A 9-month-old male is found unresponsive by his father at home. The father immediately calls for emergency services and begins to assess his son's condition. One of the first things the father does is check his son's pulse.
Where should the father check for the pulse during this assessment?Your Answer:
Correct Answer: Brachial and femoral
Explanation:When assessing for a pulse in infants, the recommended areas to check are the femoral and brachial arteries. This is because the carotid pulse may be difficult to palpate due to the short neck of infants. Checking for a central pulse is important as peripheral pulses may be weaker and harder to feel, especially in unwell patients with peripheral shutdown. It is important to note that according to BLS guidelines, the carotid pulse may only be used in children over 12 months old, making it an inappropriate option for an 8-month-old infant. Therefore, options including the carotid pulse are incorrect.
Paediatric Basic Life Support Guidelines
Paediatric basic life support guidelines were updated in 2015 by the Resuscitation Council. Lay rescuers should use a compression:ventilation ratio of 30:2 for children under 1 year and between 1 year and puberty, a child is defined. If there are two or more rescuers, a ratio of 15:2 should be used.
The algorithm for paediatric basic life support starts with checking if the child is unresponsive and shouting for help. The airway should be opened, and breathing should be checked by looking, listening, and feeling for breaths. If the child is not breathing, five rescue breaths should be given, and signs of circulation should be checked.
For infants, the brachial or femoral pulse should be used, while children should use the femoral pulse. Chest compressions should be performed at a ratio of 15:2, with a rate of 100-120 compressions per minute for both infants and children. The depth of compressions should be at least one-third of the anterior-posterior dimension of the chest, which is approximately 4 cm for an infant and 5 cm for a child.
In children, the lower half of the sternum should be compressed, while in infants, a two-thumb encircling technique should be used for chest compressions. These guidelines are crucial for anyone who may need to perform basic life support on a child, and it is essential to follow them carefully to ensure the best possible outcome.

A 15-year-old boy presents to the Emergency Department with hypotension following a rugby injury. During the game, he was tackled from the side and experienced intense pain in his left lower rib cage. On examination, the patient has a pulse of 140 bpm and a blood pressure of 80/40 mmHg. There is visible bruising over the left flank and tenderness upon palpation. What is the probable diagnosis?
Your Answer:
Correct Answer: Splenic rupture
Explanation:High Impact Injuries to the Left Flank
High impact injuries to the left flank can result in damage to the spleen or kidney, as well as the ribs and soft tissue. If the patient experiences fractured ribs and hypotension, it is important to suspect a spleen rupture. Fluid resuscitation can be used to determine if the patient responds positively, and a CT scan can be arranged to confirm the diagnosis. Based on the injury grade and physical parameters, a decision can be made to either manage the injury conservatively or operate.
Observation should be conducted in a High Dependency Unit (HDU) setting initially to ensure that any deterioration in haemodynamic parameters can be addressed promptly. CT scans are also useful in trauma cases to rule out other injuries, such as hollow visceral injuries that would require a laparotomy. Renal trauma typically does not cause hypotension unless other organs are also injured, and aortic dissection would require more force.

A toddler appears normal during mealtime and is given her food to eat. While eating, she develops respiratory distress with choking and spits out much of the food through her nose and mouth. The caregiver stops the meal and seeks medical evaluation.
What is the most probable diagnosis?Your Answer:
Correct Answer: Oesophageal atresia
Explanation:There are several congenital conditions that can affect the digestive system in newborns. Oesophageal atresia is a rare condition where the oesophageal tube is interrupted, leading to a blind-ended pouch. This can cause aspiration of milk in the lungs and respiratory distress. Duodenal atresia is another congenital condition that can cause obstruction in the duodenum. It is usually detected before birth and is associated with polyhydramnios. Annular pancreas is a rare disorder where a ring of pancreas surrounds the second part of the duodenum, leading to duodenal obstruction. Infantile pyloric stenosis is a result of a hypertrophied and hyperplastic pyloric muscle, causing gastric outlet obstruction. Midgut malrotation is a disrupted development of the bowel during embryonic development, which can present with an acute volvulus in the first year of life. These conditions require prompt medical attention and may require surgical intervention.

A 7-year-old is brought in by his father who is worried about his son's right hip pain that has been ongoing for the past 7 weeks. The father reports that the pain has been getting worse and is now causing his son to wake up at night. Over the last week, he has noticed his son limping and having difficulty getting in and out of the car and bathtub.
What is the probable diagnosis?Your Answer:
Correct Answer: Perthes' disease
Explanation:Perthes disease is characterized by avascular necrosis of the femoral head, leading to progressive hip pain, stiffness, and limp. It typically affects children between the ages of 4-8 years and can take 2-3 years to heal. Slipped upper femoral epiphysis, which affects overweight or tall thin adolescents, and developmental dysplasia present differently. Transient synovitis of the hip, which resolves within 7-10 days, is not likely due to the absence of a preceding viral illness. Septic joint is also unlikely based on the given information.
Understanding Perthes’ Disease
Perthes’ disease is a degenerative condition that affects the hip joints of children, typically between the ages of 4-8 years. It is caused by a lack of blood supply to the femoral head, which leads to bone infarction and avascular necrosis. This condition is more common in boys, with around 10% of cases being bilateral. The symptoms of Perthes’ disease include hip pain, stiffness, reduced range of hip movement, and a limp. Early changes can be seen on an x-ray, such as widening of the joint space, while later changes include decreased femoral head size and flattening.
To diagnose Perthes’ disease, a plain x-ray is usually sufficient. However, if symptoms persist and the x-ray is normal, a technetium bone scan or magnetic resonance imaging may be necessary. If left untreated, Perthes’ disease can lead to complications such as osteoarthritis and premature fusion of the growth plates.
The severity of Perthes’ disease is classified using the Catterall staging system, which ranges from stage 1 (clinical and histological features only) to stage 4 (loss of acetabular integrity). Treatment options include keeping the femoral head within the acetabulum using a cast or braces, observation for children under 6 years old, and surgical management for older children with severe deformities. The prognosis for Perthes’ disease is generally good, with most cases resolving with conservative management. Early diagnosis is key to improving outcomes.

A 5-year-old girl is brought to the emergency department with a rash. Her parents deny any trauma and have no history with social services. She recently had a cold which resolved on its own.
The child has no medical history and was born at term through vaginal delivery. She has met all developmental milestones and is up-to-date with her vaccinations.
During examination, a petechial rash is observed on the child's legs. She appears healthy without other signs of bleeding.
Her blood tests show:
Hb 140 g/L Female: (120-160)
Platelets 25 * 109/L (150 - 400)
WBC 8.0 * 109/L (4.0 - 11.0)
What is the recommended course of action?Your Answer:
Correct Answer: None
Explanation:It is important to advise patients to avoid any trauma as it can impact the resolution of ITP, whether or not treatment is administered. Administering oral corticosteroids is not recommended as it is not necessary for a child who is not actively bleeding and the platelet count will typically recover on its own. Similarly, IV corticosteroids should not be used as they pose unnecessary risks for a child who will likely recover without the need for non-specific immunosuppressants. IV immunoglobulin is also not a suitable option as the child is not exhibiting any signs of active or previous bleeding and their platelet count is sufficient.
Understanding Immune Thrombocytopenia (ITP) in Children
Immune thrombocytopenic purpura (ITP) is a condition where the immune system attacks the platelets, leading to a decrease in their count. This condition is more common in children and is usually acute, often following an infection or vaccination. The antibodies produced by the immune system target the glycoprotein IIb/IIIa or Ib-V-IX complex, causing a type II hypersensitivity reaction.
The symptoms of ITP in children include bruising, a petechial or purpuric rash, and less commonly, bleeding from the nose or gums. A full blood count is usually sufficient to diagnose ITP, and a bone marrow examination is only necessary if there are atypical features.
In most cases, ITP resolves on its own within six months, without any treatment. However, if the platelet count is very low or there is significant bleeding, treatment options such as oral or IV corticosteroids, IV immunoglobulins, or platelet transfusions may be necessary. It is also advisable to avoid activities that may result in trauma, such as team sports. Understanding ITP in children is crucial for prompt diagnosis and management of this condition.

A 6-month-old girl with poor weight gain is brought to see the pediatrician. Her growth has slowed crossing 1 centile but her weight has fallen from 50th to 9th centile in the last two months.
She began weaning at 4 months with a variety of foods. Her mother says she eats well and has no other specific symptoms. On examination she appears emaciated with abdominal distension. She is rolling over and making appropriate cooing sounds.
What is the probable diagnosis?Your Answer:
Correct Answer: Gluten-sensitive enteropathy
Explanation:Coeliac Disease and Failure to Thrive in Children
Coeliac disease is a condition that usually appears after weaning and is characterized by gastrointestinal symptoms and weight loss. In children, failure to thrive may be a sign of coeliac disease, especially if they eat well and have been weaned at an appropriate age. Abdominal distension, vomiting, diarrhoea, and weight loss are the most common symptoms of coeliac disease, but it can also present with muscle wasting, anaemia, and vitamin deficiencies.
Cystic fibrosis is another condition that can cause failure to thrive, but it typically presents with a history of respiratory infections or meconium ileus in childhood. If tests for coeliac disease are negative, cystic fibrosis may be considered. Cushing’s syndrome can cause central adiposity with muscle wasting, but it is not the same as abdominal distension. Hyperthyroidism is extremely rare during infancy, and lactose intolerance presents with marked vomiting and diarrhoea, which is not consistent with the timing of weaning seen in coeliac disease.
In summary, failure to thrive in children may be a sign of coeliac disease, especially if they have been weaned at an appropriate age and are eating well. Other conditions, such as cystic fibrosis, Cushing’s syndrome, hyperthyroidism, and lactose intolerance, should also be considered and ruled out through appropriate testing.

A 14-year-old girl presents to her GP with concerns about not having started her periods. She has also not developed any other secondary sexual characteristics. Upon examination, she is found to be proportionate but notably short in stature. Additionally, she has wide-spaced nipples, low-set ears, and subtle neck webbing. What is the most likely diagnosis for this patient?
Your Answer:
Correct Answer: Aortic coarctation
Explanation:Individuals with Turner’s syndrome (XO) often exhibit physical characteristics such as a webbed neck, low set ears, and widely spaced nipples. Short stature and primary amenorrhea are common, along with a degree of puberty failure. Other physical features to look for include a wide carrying angle, down-sloping eyes with partial ptosis, and a low posterior hairline. Turner’s syndrome is frequently linked to aortic coarctation and bicuspid aortic valve, while other cardiac abnormalities may be associated with different genetic conditions.
Understanding Turner’s Syndrome
Turner’s syndrome is a genetic disorder that affects approximately 1 in 2,500 females. It is caused by the absence of one sex chromosome (X) or a deletion of the short arm of one of the X chromosomes. This condition is denoted as 45,XO or 45,X.
The features of Turner’s syndrome include short stature, a shield chest with widely spaced nipples, a webbed neck, a bicuspid aortic valve (15%), coarctation of the aorta (5-10%), primary amenorrhea, cystic hygroma (often diagnosed prenatally), a high-arched palate, a short fourth metacarpal, multiple pigmented naevi, lymphoedema in neonates (especially feet), and elevated gonadotrophin levels. Hypothyroidism is much more common in Turner’s syndrome, and there is also an increased incidence of autoimmune disease (especially autoimmune thyroiditis) and Crohn’s disease.
In summary, Turner’s syndrome is a chromosomal disorder that affects females and can cause a range of physical features and health issues. Early diagnosis and management can help individuals with Turner’s syndrome lead healthy and fulfilling lives.

You are a nurse in the pediatric ward and you assess a 7-year-old girl with a sprained ankle. During your examination, you observe some bruises on her arms. When you ask her about it, she becomes quiet and avoids eye contact. Her father quickly intervenes and explains that she fell off her bike. However, you have a gut feeling that something is not right. What steps do you take next?
Your Answer:
Correct Answer: Put the child's arm in a cast and admit them, then contact child protection
Explanation:The GMC’s good medical practice provides guidelines for safeguarding children and young people. It emphasizes the importance of considering all possible causes of an injury or signs of abuse or neglect, including rare genetic conditions. However, the clinical needs of the child must not be overlooked in the process. If concerns persist after discussing with parents, it is necessary to report to the appropriate agency. In this scenario, delaying action while the child is under your care is not acceptable. Therefore, contacting child protection would be the appropriate course of action.
NICE Guidelines for Suspecting Child Maltreatment
The National Institute for Health and Care Excellence (NICE) has published guidelines on when to suspect child maltreatment, which includes physical, emotional, and sexual abuse, neglect, and fabricated or induced illness. The guidelines provide a comprehensive list of features that should raise suspicion of abuse, with selected features highlighted for each type of abuse.
For neglect, features such as severe and persistent infestations, failure to administer essential prescribed treatment, and inadequate provision of food and living environment that affects the child’s health should be considered as abuse. On the other hand, neglect should be suspected when parents persistently fail to obtain treatment for tooth decay, attend essential follow-up appointments, or engage with child health promotion.
For sexual abuse, persistent or recurrent genital or anal symptoms associated with a behavioral or emotional change, sexualized behavior in a prepubertal child, and STI in a child younger than 12 years without evidence of vertical or blood transmission should be considered as abuse. Suspected sexual abuse should be reported when there is a gaping anus in a child during examination without a medical explanation, pregnancy in a young woman aged 13-15 years, or hepatitis B or anogenital warts in a child aged 13-15 years.
For physical abuse, any serious or unusual injury with an absent or unsuitable explanation, bruises, lacerations, or burns in a non-mobile child, and one or more fractures with an unsuitable explanation, including fractures of different ages and X-ray evidence of occult fractures, should be considered as abuse. Physical abuse should be suspected when there is an oral injury in a child with an absent or suitable explanation, cold injuries or hypothermia in a child without a suitable explanation, or a human bite mark not by a young child.
Overall, healthcare professionals should be vigilant in identifying signs of child maltreatment and report any suspicions to the appropriate authorities.

Liam is an 8-year-old boy brought in by his father with a 2 day history of fever and sore throat. Today he has developed a rash on his torso. He is eating and drinking well, but has not been to school for the last 2 days and has been feeling tired.
On examination, Liam is alert, smiling and playful. He has a temperature of 37.8°C. His throat appears red with petechiae on the hard and soft palate and his tongue is covered with a white coat through which red papillae are visible. There is a blanching rash present on his trunk which is red and punctate with a rough, sandpaper-like texture.
What is the appropriate time for Liam to return to school, given the most likely diagnosis?Your Answer:
Correct Answer: 24 hours after commencing antibiotics
Explanation:If a child has scarlet fever, they can go back to school after 24 hours of starting antibiotics. The symptoms described are typical of scarlet fever, including a strawberry tongue and a rough-textured rash with small red spots on the palate called Forchheimer spots. Charlotte doesn’t need to be hospitalized but should take a 10-day course of phenoxymethylpenicillin (penicillin V). According to NICE, the child should stay away from school, nursery, or work for at least 24 hours after starting antibiotics. It’s also important to advise parents to take measures to prevent cross-infection, such as frequent handwashing, avoiding sharing utensils and towels, and disposing of tissues promptly.
Scarlet fever is a condition caused by erythrogenic toxins produced by Group A haemolytic streptococci, usually Streptococcus pyogenes. It is more prevalent in children aged 2-6 years, with the highest incidence at 4 years. The disease spreads through respiratory droplets or direct contact with nose and throat discharges, especially during sneezing and coughing. The incubation period is 2-4 days, and symptoms include fever, malaise, headache, nausea/vomiting, sore throat, ‘strawberry’ tongue, and a rash that appears first on the torso and spares the palms and soles. The rash has a rough ‘sandpaper’ texture and desquamation occurs later in the course of the illness, particularly around the fingers and toes.
To diagnose scarlet fever, a throat swab is usually taken, but antibiotic treatment should be initiated immediately, rather than waiting for the results. Management involves administering oral penicillin V for ten days, while patients with a penicillin allergy should be given azithromycin. Children can return to school 24 hours after commencing antibiotics, and scarlet fever is a notifiable disease. Although usually a mild illness, scarlet fever may be complicated by otitis media, rheumatic fever, acute glomerulonephritis, or rare invasive complications such as bacteraemia, meningitis, or necrotizing fasciitis, which may present acutely with life-threatening illness.

A worried father brings his 12-month-old son to the GP because he is worried about his development.
You conduct a developmental evaluation.
What results in the child would be worrisome?Your Answer:
Correct Answer: Picks up objects with a pincer grip, with a preference for the right hand
Explanation:Hand preference before the age of 12 months may indicate a potential issue such as cerebral palsy. It is not typical for a child to strongly favor one hand over the other at this age. However, it is encouraging for a 10-month-old to have a vocabulary of at least three words. It is normal for children to play alone at this age and they are not expected to share toys until they are around 3 years old. It is also normal for children to enjoy casting bricks until they are 18 months old, but if this behavior continues beyond that age, it may be a cause for concern. Finally, independent walking should develop between 9 and 18 months, with 18 months being the age at which parents may want to seek medical advice if their child is not yet walking independently.
Common Developmental Problems and Possible Causes
Developmental problems can manifest in various ways, including referral points such as not smiling at 10 weeks, inability to sit unsupported at 12 months, and failure to walk at 18 months. Fine motor skill problems may also arise, such as abnormal hand preference before 12 months, which could indicate cerebral palsy. Gross motor problems are often caused by a variant of normal, cerebral palsy, or neuromuscular disorders like Duchenne muscular dystrophy. Speech and language problems should always be checked for hearing issues, as they can also be caused by environmental deprivation or general development delay.
It is important to recognize these developmental problems early on and seek appropriate interventions to address them. By doing so, children can receive the necessary support to reach their full potential and overcome any challenges they may face. With proper care and attention, many children with developmental problems can go on to lead happy and fulfilling lives.

A 6-year-old girl arrives at the emergency department with complaints of pain in the right iliac fossa. Upon examination, there is no rebound tenderness or guarding. Routine bloods and urine dipstick tests show normal results. The child's mother mentions that her daughter had a viral infection a few days ago. What is the most probable diagnosis?
Your Answer:
Correct Answer: Mesenteric adenitis
Explanation:Abdominal tenderness and guarding are indicative of appendicitis, while a negative urine dipstick is not typical of pyelonephritis.
Mesenteric adenitis refers to the inflammation of lymph nodes located in the mesentery. This condition can cause symptoms that are similar to those of appendicitis, making it challenging to differentiate between the two. Mesenteric adenitis is commonly observed after a recent viral infection and typically does not require any treatment.

A 9-month-old girl is brought to your clinic by her parents, reporting an atypical sequence of movements observed in their daughter. They managed to record a video of the episode, and upon reviewing it, you observe mild bilateral flexion of her neck and legs, succeeded by extension of her arms. She repeats this pattern approximately 40 times before ceasing.
What is the probable diagnosis for this scenario?Your Answer:
Correct Answer: Infantile spasms
Explanation:Understanding Infantile Spasms
Infantile spasms, also known as West syndrome, is a form of epilepsy that typically occurs in infants between 4 to 8 months old, with a higher incidence in male infants. This condition is often associated with a serious underlying condition and has a poor prognosis. The characteristic feature of infantile spasms is the salaam attacks, which involve the flexion of the head, trunk, and arms followed by the extension of the arms. These attacks last only 1-2 seconds but can be repeated up to 50 times.
Infants with infantile spasms may also experience progressive mental handicap. To diagnose this condition, an EEG is typically performed, which shows hypsarrhythmia in two-thirds of infants. Additionally, a CT scan may be used to identify any diffuse or localized brain disease, which is present in 70% of cases, such as tuberous sclerosis.
Unfortunately, infantile spasms carry a poor prognosis. However, there are treatment options available. Vigabatrin is now considered the first-line therapy, and ACTH is also used.

A 16-week-old infant is brought to the GP by their mother due to regurgitation and vomiting after most feeds, ongoing diarrhea with significant amounts of mucous, and difficulty settling. The mother also reports that the infant often pulls their legs up to their chest during crying episodes. The infant was born at full term, had a healthy weight at birth, and is formula-fed. They have a history of eczema managed with emollients. What is the recommended next step in management?
Your Answer:
Correct Answer: Trial of extensively hydrolysed formula
Explanation:In case of mild-moderate cow’s milk protein intolerance in a baby who is fed with formula, it is recommended to switch to an extensively hydrolyzed formula.
Understanding Cow’s Milk Protein Intolerance/Allergy
Cow’s milk protein intolerance/allergy (CMPI/CMPA) is a condition that affects around 3-6% of children, typically presenting in the first 3 months of life in formula-fed infants. Both immediate and delayed reactions can occur, with CMPA used for immediate reactions and CMPI for mild-moderate delayed reactions. Symptoms include regurgitation, vomiting, diarrhea, urticaria, atopic eczema, colic symptoms, wheeze, chronic cough, and rarely, angioedema and anaphylaxis. Diagnosis is often clinical, with investigations including skin prick/patch testing and total IgE and specific IgE (RAST) for cow’s milk protein.
Management for formula-fed infants includes using extensive hydrolyzed formula (eHF) milk as the first-line replacement formula for mild-moderate symptoms and amino acid-based formula (AAF) for severe CMPA or if no response to eHF. Around 10% of infants are also intolerant to soya milk. For breastfed infants, mothers should eliminate cow’s milk protein from their diet and consider prescribing calcium supplements to prevent deficiency. eHF milk can be used when breastfeeding stops until at least 6 months and up to 12 months of age.
The prognosis for CMPI is usually good, with most children becoming milk tolerant by the age of 3-5 years. However, a challenge is often performed in a hospital setting as anaphylaxis can occur. It is important to refer infants with severe symptoms to a pediatrician for management. Understanding CMPI/CMPA and its management can help parents and healthcare providers provide appropriate care for affected children.
