Question 1
Correct
-
A 9-month old infant is brought to the pediatrician by his parents. They report that he has had a runny nose and mild fever for the past week. Today, they noticed that he appeared paler than usual, has been increasingly lethargic, and seems to be struggling to breathe.
During the examination, the infant exhibits normal coloring, but there is moderate intercostal recession and nasal flaring. He only responds to chest rubbing after 5 seconds. His pulse rate is 140 beats per minute, respiratory rate is 40 breaths per minute, oxygen saturation is 94% on room air, and temperature is 37.9 ºC.
What is the most concerning aspect of this presentation as a sign of a serious illness?Your Answer: Intercostal recession
Explanation:An amber flag (intermediate risk) on the traffic light system indicates that the patient is on room air. For infants aged 12 months or older, a respiratory rate of over 40 breaths per minute would also be considered an amber flag, but not for a 6-12-month-old in this particular case.
The NICE Feverish illness in children guidelines were introduced in 2007 and updated in 2013. These guidelines use a ‘traffic light’ system to assess the risk of children under 5 years old presenting with a fever. It is important to note that these guidelines only apply until a clinical diagnosis of the underlying condition has been made. When assessing a febrile child, their temperature, heart rate, respiratory rate, and capillary refill time should be recorded. Signs of dehydration should also be looked for. Measuring temperature should be done with an electronic thermometer in the axilla if the child is under 4 weeks old or with an electronic/chemical dot thermometer in the axilla or an infrared tympanic thermometer.
The risk stratification table includes green for low risk, amber for intermediate risk, and red for high risk. The table includes categories such as color, activity, respiratory, circulation and hydration, and other symptoms. If a child is categorized as green, they can be managed at home with appropriate care advice. If they are categorized as amber, parents should be provided with a safety net or referred to a pediatric specialist for further assessment. If a child is categorized as red, they should be urgently referred to a pediatric specialist. It is important to note that oral antibiotics should not be prescribed to children with fever without an apparent source, and a chest x-ray does not need to be routinely performed if a pneumonia is suspected but the child is not going to be referred to the hospital.

Question 2
Correct

An 8-year-old boy comes to the paediatric department with a 5-day history of epistaxis and mucosal bleeding during tooth brushing. He has no significant medical history except for a cold he had 3 weeks ago. Upon examination, his vital signs are normal, but he has multiple bruises and petechiae on his upper and lower limbs. The following laboratory tests were ordered: Hb 140 g/L (135-180), Platelets 33 * 109/L (150 - 400), WBC 7.3 * 109/L (4.0 - 11.0), Na+ 138 mmol/L (135 - 145), K+ 4.1 mmol/L (3.5 - 5.0), Urea 5.1 mmol/L (2.0 - 7.0), Creatinine 110 µmol/L (55 - 120). What is the most probable diagnosis?
Your Answer: Immune thrombocytopenic purpura
Explanation:When a child presents with petechiae and no fever, ITP should be considered as a possible diagnosis. ITP is an autoimmune disorder that causes thrombocytopenia without any identifiable cause. It is most commonly found in children and women and often follows a viral illness. Symptoms include mucosal bleeding, epistaxis, petechiae, and bruising.
Acute lymphoblastic leukaemia is an unlikely diagnosis in this case, as the patient’s normal haemoglobin and white cell count do not suggest malignancy.
Disseminated intravascular coagulation (DIC) is also unlikely, as there is no evidence of unregulated bleeding or thrombosis triggered by trauma, sepsis, obstetric disorders, or malignancy.
Henoch-Schönlein purpura (HSP) is another possible diagnosis, but the lack of additional symptoms and the presence of bruising and easy bleeding make ITP more likely. HSP is a form of IgA vasculitis that causes a palpable purpuric rash, abdominal pain, and arthralgia, and is commonly triggered by a viral infection. Most cases of HSP are self-limiting or resolve with symptomatic treatment.
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 9-month-old girl is brought to their GP due to family concerns over the child's development. They were born at term via vaginal delivery, without complications. The child is otherwise well, without past medical history.
What developmental milestone would be most anticipated in this child?Your Answer: Good pincer grip
Correct Answer: Pass objects from one hand to another
Explanation:A 6-month-old boy was brought to the GP by his family who were concerned about his development. The GP tested his developmental milestones and found that he was able to hold objects with palmar grasp and pass objects from one hand to another. However, the child was not yet able to build a tower of 2 bricks, have a good pincer grip, or show a hand preference, which are expected milestones for older children. The GP reassured the family that the child’s development was within the normal range for his age.
Developmental Milestones for Fine Motor and Vision Skills
Fine motor and vision skills are important developmental milestones for infants and young children. These skills are crucial for their physical and cognitive development. The following tables provide a summary of the major milestones for fine motor and vision skills.
At three months, infants can reach for objects and hold a rattle briefly if given to their hand. They are visually alert, particularly to human faces, and can fix and follow objects up to 180 degrees. By six months, they can hold objects in a palmar grasp and pass them from one hand to another. They are visually insatiable, looking around in every direction.
At nine months, infants can point with their finger and demonstrate an early pincer grip. By 12 months, they have developed a good pincer grip and can bang toys together and stack bricks.
As children grow older, their fine motor skills continue to develop. By 15 months, they can build a tower of two blocks, and by 18 months, they can build a tower of three blocks. By two years old, they can build a tower of six blocks, and by three years old, they can build a tower of nine blocks. They also begin to draw, starting with circular scribbles at 18 months and progressing to copying vertical lines at two years old, circles at three years old, crosses at four years old, and squares and triangles at five years old.
In addition to fine motor skills, children’s vision skills also develop over time. At 15 months, they can look at a book and pat the pages. By 18 months, they can turn several pages at a time, and by two years old, they can turn one page at a time.
It is important to note that hand preference before 12 months is abnormal and may indicate cerebral palsy. Overall, these developmental milestones for fine motor and vision skills are important indicators of a child’s growth and development.

A 9-year-old girl presents with a 1-day history of abdominal pain. Her mother reports that the pain woke the child up this morning, with one episode of vomiting this afternoon, and she has since lost her appetite. She has had no fever or diarrhoea. There is no history of foreign travel and no ill contacts. On examination, the temperature is 37.5 °C and heart rate (HR) 123 bpm, and there is generalised abdominal tenderness, without guarding or rigidity. Urine dip is negative, and blood tests show white cell count (WCC) of 15 with C-reactive protein (CRP) of 10.
What would the next best step in management be?Your Answer: Discharge with oral analgesia
Correct Answer: Nil by mouth, intravenous fluids and review
Explanation:Management of Appendicitis in Children: Nil by Mouth, Laparoscopy, and Monitoring
Appendicitis in children can present with atypical symptoms, such as general abdominal pain, anorexia, and vomiting, accompanied by a low-grade fever. If a child presents with these symptoms, it is important to suspect appendicitis and admit the child for monitoring.
The first line of management is to keep the child nil by mouth and monitor their condition closely. If the child’s pain worsens or their condition deteriorates, a diagnostic or Exploratory laparoscopy may be necessary, with or without an appendicectomy.
While a laparotomy may be necessary in emergency situations where the child is haemodynamically unstable, a laparoscopic appendicectomy is usually the preferred option.
An abdominal X-ray is not the best diagnostic tool for appendicitis, but it can rule out bowel perforation and free pneumoperitoneum. Ultrasound is the preferred modality for children due to the lower radiation dose compared to CT scans.
It is crucial to monitor the child’s condition closely and prevent any complications from a perforated appendix. Discharge with oral analgesia is not recommended if the child is tachycardic and has a low-grade fever, as these symptoms can be associated with peritonitis. Overall, early recognition and prompt management are essential in the successful treatment of appendicitis in children.

A couple, one male and one female, seek genetic counselling as a family member has been diagnosed with sickle cell anaemia, an autosomal recessive condition. After testing, it is discovered that both individuals are carriers of sickle cell anaemia. The woman is currently 16 weeks pregnant.
What is the likelihood that their unborn child will also be a carrier of sickle cell anaemia?Your Answer: 25%
Correct Answer: 50%
Explanation:The statement is incorrect because if at least one parent is a carrier of sickle cell anemia, there is a probability greater than zero.
Understanding Autosomal Recessive Inheritance
Autosomal recessive inheritance is a genetic pattern where a disorder is only expressed when an individual inherits two copies of a mutated gene, one from each parent. This means that only homozygotes, individuals with two copies of the mutated gene, are affected. Both males and females are equally likely to be affected, and the disorder may not manifest in every generation, as it can skip a generation.
When two heterozygote parents, carriers of the mutated gene, have children, there is a 25% chance of having an affected (homozygote) child, a 50% chance of having a carrier (heterozygote) child, and a 25% chance of having an unaffected child. On the other hand, if one parent is homozygote for the gene and the other is unaffected, all the children will be carriers.
Autosomal recessive disorders are often metabolic in nature and can be life-threatening compared to autosomal dominant conditions. Understanding the inheritance pattern of autosomal recessive disorders is crucial in genetic counseling and family planning.

A 6-year-old girl is brought to the emergency department by her parents after she was woken up from sleep at night with unilateral jerking movements of the left face and upper limb lasting for 2 minutes. During the episode, she did not lose consciousness. This has only happened once before a few nights ago.
A neurological examination is unremarkable, and her temperature is 37.5ºC and her heart rate is 90 bpm. She is slightly drowsy. Another episode occurs and an EEG is performed, which shows centrotemporal spikes.
She has no past medical history.
What is the most likely diagnosis?Your Answer: Benign rolandic epilepsy
Explanation:The child’s symptoms and medical history suggest that they have benign rolandic epilepsy, which is characterized by partial seizures occurring at night. This type of epilepsy typically affects children between the ages of 4 and 12 and is confirmed by an EEG showing centrotemporal spikes. The seizures originate from the central sulcus of the brain in a region called the Rolandic fissure. Although the child is drowsy, postictal states can occur in benign rolandic epilepsy as well. The prognosis for this condition is usually excellent, with most children outgrowing it. Febrile convulsions, generalised tonic-clonic epilepsy, and infantile spasms are not applicable to this case.
Benign rolandic epilepsy is a type of epilepsy that usually affects children between the ages of 4 and 12 years. This condition is characterized by seizures that typically occur at night and are often partial, causing sensations in the face. However, these seizures may also progress to involve the entire body. Despite these symptoms, children with benign rolandic epilepsy are otherwise healthy and normal.
Diagnosis of benign rolandic epilepsy is typically confirmed through an electroencephalogram (EEG), which shows characteristic centrotemporal spikes. Fortunately, the prognosis for this condition is excellent, with seizures typically ceasing by adolescence. While the symptoms of benign rolandic epilepsy can be concerning for parents and caregivers, it is important to remember that this condition is generally not associated with any long-term complications or developmental delays.

A 17 month old girl comes to your GP clinic with symptoms of a viral URTI. While examining her, you notice some developmental concerns. What would be the most worrying sign?
Your Answer: Unable to say 6 individual words with meaning
Explanation:1. At 23-24 months, children typically have a vocabulary of 20-50 words and can form 2-word phrases with meaning.
2. Toilet training usually occurs at or after 3 years of age.
3. By 3 years of age, most children can stand briefly on one leg and hop by age 4.
4. Walking is typically achieved by 18 months, although most children will walk before 17 months.
5. It is common for 23-month-old children to engage in solitary play.Developmental milestones for speech and hearing are important indicators of a child’s growth and development. These milestones can help parents and caregivers track a child’s progress and identify any potential issues early on. At three months, a baby should be able to quieten to their parents’ voice and turn towards sound. They may also start to squeal. By six months, they should be able to produce double syllables like adah and erleh. At nine months, they may say mama and dada and understand the word no. By 12 months, they should know and respond to their own name and understand simple commands like give it to mummy.
Between 12 and 15 months, a child may know about 2-6 words and understand more complex commands. By two years old, they should be able to combine two words and point to parts of their body. Their vocabulary should be around 200 words by 2 1/2 years old. At three years old, they should be able to talk in short sentences and ask what and who questions. They may also be able to identify colors and count to 10. By four years old, they may start asking why, when, and how questions. These milestones are important to keep in mind as a child grows and develops their speech and hearing abilities.

A 9-year-old girl presents to the Emergency department with a three day history of limping. She has been experiencing illness recently. Upon examination, she has no fever and shows discomfort when moving her hip. What is the probable diagnosis?
Your Answer: Transient synovitis
Explanation:Transient Synovitis in Childhood: the Causes and Diagnosis
Transient synovitis is a prevalent cause of hip pain in children, but it is crucial to rule out other more severe causes before diagnosing it. The exact cause of this condition is still unknown, but it is believed to be associated with viral infections, allergic reactions, or trauma.
Transient synovitis is a self-limiting condition that typically resolves within a few days to weeks. However, it is essential to differentiate it from other conditions that may require urgent medical attention, such as septic arthritis or Legg-Calve-Perthes disease. Therefore, a thorough medical history, physical examination, and imaging studies are necessary to make an accurate diagnosis.
In conclusion, transient synovitis is a common cause of hip pain in childhood, but it is crucial to exclude other more serious conditions before diagnosing it. Parents should seek medical attention if their child experiences hip pain, limping, or difficulty walking to ensure prompt and appropriate treatment.

You are assessing a 9-month-old infant with suspected bronchiolitis. What sign or symptom should raise concern for a possible hospital referral?
Your Answer: Feeding 50% of the normal amount
Explanation:Bronchiolitis is a condition where the bronchioles become inflamed, and it is most commonly caused by respiratory syncytial virus (RSV). This virus is responsible for 75-80% of cases, with other causes including mycoplasma and adenoviruses. Bronchiolitis is most prevalent in infants under one year old, with 90% of cases occurring in those aged 1-9 months. The condition is more serious in premature babies, those with congenital heart disease or cystic fibrosis. Symptoms include coryzal symptoms, dry cough, increasing breathlessness, and wheezing. Hospital admission is often necessary due to feeding difficulties associated with increasing dyspnoea.
Immediate referral is recommended if the child has apnoea, looks seriously unwell, has severe respiratory distress, central cyanosis, or persistent oxygen saturation of less than 92% when breathing air. Clinicians should consider referral if the child has a respiratory rate of over 60 breaths/minute, difficulty with breastfeeding or inadequate oral fluid intake, or clinical dehydration. Immunofluorescence of nasopharyngeal secretions may show RSV, and management is largely supportive. Humidified oxygen is given via a head box if oxygen saturations are persistently low, and nasogastric feeding may be necessary if children cannot take enough fluid/feed by mouth. Suction may also be used for excessive upper airway secretions. NICE released guidelines on bronchiolitis in 2015 for more information.

A 16-year-old boy attends the Emergency Department (ED) with his father. They are both heavily intoxicated with alcohol. The boy’s records show that this is the fourth time in eight months that he has attended the ED with alcohol-related problems. The safeguarding lead has advised you to contact social services.
What is the most suitable course of action in this scenario?Your Answer: Refer urgently to social services without informing the patient or her mother
Correct Answer: Inform the patient and her mother you are referring them to social services
Explanation:Referring a Child at Risk to Social Services: Best Practices
When a child is believed to be at risk, it is crucial to refer them to social services for safeguarding. However, the process of making a referral can be sensitive and requires careful consideration. Here are some best practices to follow:
1. Inform the patient and their parent/guardian about the referral: It is important to inform the patient and their parent/guardian that a referral to social services is being made. However, if there is a risk that informing them could put the child in further danger, the referral should be made without informing them.
2. Seek consent for the referral: Consent should be sought from the patient or their parent/guardian before making a referral. If consent is refused, the referral should still be made, but the patient and/or parent must be fully informed.
3. Refer urgently: If there is a concern that the child is at immediate risk, the referral should be made urgently.
4. Follow up with a written referral: A phone referral should be made initially, but it is important to follow up with a written referral within 48 hours.
By following these best practices, healthcare professionals can ensure that children at risk receive the support and protection they need.
