Question 1
Correct

A 4-year-old girl comes to the doctor's office with a diffuse, blanching, erythematosus rash all over her trunk, arms, and legs. She has been running a fever and feeling generally cranky and tired for about a week. Additionally, she has been experiencing abdominal discomfort for the past few days. During the examination, the doctor notices that the skin on her palms and soles is peeling, and her tongue is red with a white coating. What is the probable diagnosis?
Your Answer: Kawasaki disease
Explanation:Kawasaki disease can be identified by a combination of symptoms, including a high fever lasting more than five days, red palms with peeling skin, and a strawberry tongue. If a fever lasts for more than five days and is accompanied by desquamation and strawberry tongue, it is likely to be Kawasaki disease. Scarlet fever also causes skin peeling and strawberry tongue, but the fever is not as prolonged. Meningitis causes a non-blanching rash and more severe symptoms, while Henoch-Schonlein purpura presents with a non-blanching rash, abdominal pain, joint pain, and haematuria.
Understanding Kawasaki Disease
Kawasaki disease is a rare type of vasculitis that primarily affects children. It is important to identify this disease early on as it can lead to serious complications, such as coronary artery aneurysms. The disease is characterized by a high-grade fever that lasts for more than five days and is resistant to antipyretics. Other symptoms include conjunctival injection, bright red, cracked lips, strawberry tongue, cervical lymphadenopathy, and red palms and soles that later peel.
Diagnosis of Kawasaki disease is based on clinical presentation as there is no specific diagnostic test available. Management of the disease involves high-dose aspirin, which is one of the few indications for aspirin use in children. Intravenous immunoglobulin is also used as a treatment option. Echocardiogram is the initial screening test for coronary artery aneurysms, rather than angiography.
Complications of Kawasaki disease can be serious, with coronary artery aneurysm being the most common. It is important to recognize the symptoms of Kawasaki disease early on and seek medical attention promptly to prevent potential complications.

A baby boy born 3 weeks ago has been experiencing persistent jaundice since 72 hours after birth. His parents have observed that he is hesitant to breastfeed and his urine appears dark. During your examination, you confirm that the infant is jaundiced and has an enlarged liver. Upon reviewing his blood work, you find that he has conjugated hyperbilirubinemia. His serum alpha-1 antitrypsin levels and electrophoresis are normal, and the neonatal heel prick test conducted at birth was negative. What is the recommended treatment for this condition?
Your Answer: Early surgical treatment
Explanation:Biliary atresia is the primary cause of prolonged jaundice in this infant, which occurs due to an obstruction in the flow of bile within the extrahepatic biliary system. To confirm the diagnosis, bilirubin levels, liver function tests, and abdominal ultrasound are performed, while alpha-1 antitrypsin deficiency and cystic fibrosis are excluded as differential diagnoses. The Kasai procedure, a surgical intervention, is the preferred treatment option to restore bile flow and prevent further hepatic damage. Postoperative management may involve IV antibiotics to manage complications such as ascending cholangitis, while ursodeoxycholic acid may be used to augment weight gain and decrease episodes of cholangitis. Optimizing feeds is also important, but not the primary management option in this case, as the heel prick test has excluded CF. Infusion of alpha-1 antitrypsin is not necessary, as the infant’s serum levels are normal.
Understanding Biliary Atresia in Neonatal Children
Biliary atresia is a condition that affects the extrahepatic biliary system in neonatal children, resulting in an obstruction in the flow of bile. This condition is more common in females than males and occurs in 1 in every 10,000-15,000 live births. There are three types of biliary atresia, with type 3 being the most common. Patients typically present with jaundice, dark urine, pale stools, and abnormal growth.
To diagnose biliary atresia, doctors may perform various tests, including serum bilirubin, liver function tests, serum alpha 1-antitrypsin, sweat chloride test, and ultrasound of the biliary tree and liver. Surgical intervention is the only definitive treatment for biliary atresia, and medical intervention includes antibiotic coverage and bile acid enhancers following surgery.
Complications of biliary atresia include unsuccessful anastomosis formation, progressive liver disease, cirrhosis, and eventual hepatocellular carcinoma. However, the prognosis is good if surgery is successful. In cases where surgery fails, liver transplantation may be required in the first two years of life. Overall, understanding biliary atresia is crucial for early diagnosis and effective management in neonatal children.

A 24-hour old baby is evaluated in the neonatal intensive care unit due to tremors in his limbs, as observed by his nurse. He is also experiencing poor feeding, increased irritability, and excessive drowsiness. The baby was delivered via emergency caesarean section at 34 weeks due to reduced foetal movements and foetal bradycardia. The mother had an otherwise healthy pregnancy, but was taking lamotrigine for epilepsy. During the examination, the baby appeared larger than expected for his prematurity and exhibited visible arm tremors. Based on these symptoms, which aspect of the baby's medical history is most likely responsible for his condition?
Your Answer: Maternal lamotrigine use
Correct Answer: Prematurity
Explanation:Prematurity is a significant risk factor for neonatal hypoglycaemia, which is characterized by autonomic symptoms such as irritability and jitteriness, as well as neuroglycopenic symptoms like drowsiness and poor feeding. This is because preterm infants have not yet developed the same glycogen reserve as term infants. Admission to the neonatal intensive care unit, delivery via emergency caesarean section, formula feeding, and maternal lamotrigine use are not independent risk factors for neonatal hypoglycaemia. While caesarean section may result in transient hypoglycaemia, it is not typically symptomatic due to the lack of catecholamine release present during vaginal delivery. Terbutaline use, on the other hand, may increase the risk of hypoglycaemia.
Neonatal Hypoglycaemia: Causes, Symptoms, and Management
Neonatal hypoglycaemia is a common condition in newborn babies, especially in the first 24 hours of life. While there is no agreed definition, a blood glucose level of less than 2.6 mmol/L is often used as a guideline. Transient hypoglycaemia is normal and usually resolves on its own, but persistent or severe hypoglycaemia may be caused by various factors such as preterm birth, maternal diabetes mellitus, IUGR, hypothermia, neonatal sepsis, inborn errors of metabolism, nesidioblastosis, or Beckwith-Wiedemann syndrome.
Symptoms of neonatal hypoglycaemia can be autonomic, such as jitteriness, irritability, tachypnoea, and pallor, or neuroglycopenic, such as poor feeding/sucking, weak cry, drowsiness, hypotonia, and seizures. Other features may include apnoea and hypothermia. Management of neonatal hypoglycaemia depends on the severity of the condition and whether the newborn is symptomatic or not. Asymptomatic babies can be encouraged to feed normally and have their blood glucose monitored, while symptomatic or severely hypoglycaemic babies may need to be admitted to the neonatal unit and receive intravenous infusion of 10% dextrose.

A 3-day-old baby has not passed meconium yet. Your consultant suspects Hirschsprung's disease and asks for your initial management plan. What would be the best initial treatment for this child until a definite diagnosis is made and more specific treatment can be given?
Your Answer: Full Thickness Rectal Biopsy
Correct Answer: Bowel Irrigation
Explanation:The first step in managing Hirschsprung’s disease is to perform rectal washouts or bowel irrigation. While waiting for a full thickness rectal biopsy to confirm the diagnosis, this treatment can help the baby pass meconium. Once the diagnosis is confirmed, the definitive management is an anorectal pull through procedure. It is important to note that anorectal pull through is not the initial treatment but rather the final solution. Lactulose is not appropriate for constipation in children with Hirschsprung’s disease. Rectal biopsy is only used for diagnostic purposes.
Understanding Hirschsprung’s Disease
Hirschsprung’s disease is a rare condition that affects 1 in 5,000 births. It is caused by a developmental failure of the parasympathetic Auerbach and Meissner plexuses, resulting in an aganglionic segment of bowel. This leads to uncoordinated peristalsis and functional obstruction, which can present as constipation and abdominal distension in older children or failure to pass meconium in the neonatal period.
Hirschsprung’s disease is three times more common in males and is associated with Down’s syndrome. Diagnosis is made through a rectal biopsy, which is considered the gold standard. Treatment involves initial rectal washouts or bowel irrigation, followed by surgery to remove the affected segment of the colon.
In summary, Hirschsprung’s disease is a rare condition that can cause significant gastrointestinal symptoms. It is important to consider this condition as a differential diagnosis in childhood constipation, especially in male patients or those with Down’s syndrome. Early diagnosis and treatment can improve outcomes and prevent complications.

Question 5
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.

Question 6

The mother of a 3-year-old boy contacts you for advice on febrile convulsions. Her son had his first seizure a few days ago while suffering from a viral respiratory infection. She describes it as a typical, simple febrile convulsion lasting 2-3 minutes with full recovery in about 30 minutes. The mother recalls being informed that there is a risk of recurrence, but she was not given any treatment and was discharged home. She wants to know when she should call an ambulance if it happens again.
Your Answer: A further simple febrile convulsion lasting > 5 minutes
Explanation:Parents should be informed that if their child experiences a febrile convulsion lasting more than 5 minutes, they should call for an ambulance. While some children may have recurrent febrile convulsions, simple ones typically last up to 15 minutes and result in complete recovery within an hour. In these cases, parents can manage their child at home with clear guidance on when to seek medical help, including the use of buccal midazolam or rectal diazepam. However, if a febrile convulsion lasts longer than 5 minutes, an ambulance should be called. If there is a subsequent convulsion lasting less than 5 minutes with a recovery time of 30-60 minutes, the child may be able to stay at home. However, if a febrile convulsion lasts longer than 10 or 15 minutes, an ambulance should have already been called after the initial 5 minutes.
Febrile convulsions are seizures caused by fever in children aged 6 months to 5 years. They typically last less than 5 minutes and are most commonly tonic-clonic. There are three types: simple, complex, and febrile status epilepticus. Children who have had a first seizure or any features of a complex seizure should be admitted to pediatrics. Regular antipyretics do not reduce the chance of a febrile seizure occurring. The overall risk of further febrile convulsion is 1 in 3, with risk factors including age of onset, fever duration, family history, and link to epilepsy. Children without risk factors have a 2.5% risk of developing epilepsy, while those with all three features have a much higher risk.

A 29-year-old woman undergoes antenatal haemoglobinopathy screening and is found to have sickle cell trait. The father of the child agrees to further screening and is found to have the HbAS genotype. What is the probability of their offspring having sickle cell disease?
Your Answer: 50%
Correct Answer: 25%
Explanation: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 preteen visits the sexual health clinic complaining of painful urination and penile discharge. He suspects he may have contracted a sexually transmitted infection. Upon further inquiry, you discover that he is just 10 years old, despite appearing older. When you ask about his sexual partner, he refuses to provide any additional details and insists that you keep this encounter confidential from his parents and others. What is the most appropriate course of action in this situation?
Your Answer: Explain why you are unable to keep it a secret and tell him you will have to inform social services and his parents
Explanation:Referral to social services for investigation is necessary as this may be a case of sexual abuse, particularly since the child involved is under 13 years old and may not have been able to give consent. As per GMC guidelines, it is recommended to share information about such sexual activity involving children under 13.
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.

Which one of the following statements regarding bronchiolitis is true?
Your Answer: Peak incidence is 3-6 months of age
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 worried 28-year-old mother expresses concern about a lump that has emerged on her infant's head, stating with certainty that it was not present at birth and was only noticed half an hour ago. The baby was delivered vaginally with forceps 10 hours ago at 39 weeks gestation.
Upon examination, there is a clearly defined, soft swelling that does not cross suture lines and is located on the parietal bone. The baby appears to be in good health otherwise, with normal skin color and tone, as well as regular vital signs.
What is the most probable diagnosis?Your Answer: Cephalhaematoma
Explanation:The most likely diagnosis for the newborn baby’s well-demarcated, fluctuant swelling that appeared two days after birth is cephalohaematoma. This is a haemorrhage between the skull and periosteum that occurs when blood vessels crossing the periosteum rupture. The swelling is limited by the individual bones and does not cross suture lines. It may take months to resolve as the blood clot is reabsorbed. Cephalohaematoma is more common in prolonged and/or instrumental deliveries and may lead to jaundice, anaemia or hypotension if severe. It may also indicate a linear skull fracture or risk of infection. Caput succedaneum, chignon, normal skull shape, and subgaleal haemorrhage are less likely diagnoses.
A cephalohaematoma is a swelling that appears on a newborn’s head, usually a few hours after delivery. It is caused by bleeding between the skull and periosteum, with the parietal region being the most commonly affected site. This condition may lead to jaundice as a complication and can take up to three months to resolve.
In comparison to caput succedaneum, which is another type of swelling that can occur on a newborn’s head, cephalohaematoma is more localized and does not cross suture lines. Caput succedaneum, on the other hand, is a diffuse swelling that can cross suture lines and is caused by fluid accumulation in the scalp tissue. Both conditions are usually harmless and resolve on their own, but medical attention may be necessary in severe cases.

A 16-month-old boy has been diagnosed with roseola infantum. What is the most frequent complication associated with this illness?
Your Answer: Orchitis
Correct Answer: Febrile convulsions
Explanation:Understanding Roseola Infantum
Roseola infantum, also known as exanthem subitum or sixth disease, is a common illness that affects infants and is caused by the human herpes virus 6 (HHV6). This disease has an incubation period of 5-15 days and is typically seen in children aged 6 months to 2 years. The most common symptoms of roseola infantum include a high fever that lasts for a few days, followed by a maculopapular rash. Other symptoms may include Nagayama spots, which are papular enanthems on the uvula and soft palate, as well as cough and diarrhea.
In some cases, febrile convulsions may occur in around 10-15% of children with roseola infantum. While this can be concerning for parents, it is important to note that this is a common occurrence and typically resolves on its own. Additionally, HHV6 infection can lead to other possible consequences such as aseptic meningitis and hepatitis.
It is important to note that school exclusion is not necessary for children with roseola infantum. While this illness can be uncomfortable for infants, it is typically not serious and resolves on its own within a few days.

A 14-year-old boy presents to the clinic for a routine check-up due to his recent development of poor near vision, without any history of eye trauma. He is tall, measuring at the 99th percentile for his age, and is performing well in school. During the medical history, he reports experiencing fatigue easily during physical activity. Upon examination, you observe that he has a high arched palate, pectus excavatum, and long arms. Additionally, you notice a bounding pulse and an early diastolic murmur at the left sternal edge during the cardiovascular exam. What is the most likely diagnosis?
Your Answer: Marfan syndrome
Explanation:Marfan syndrome is a connective tissue disease with cardiovascular complications such as aortic root dilation and aneurysm. Diagnosis is based on clinical features, family history, and genetic testing. The Ghent criteria are commonly used, with emphasis on cardiac manifestations. Echocardiographic surveillance is required, and prophylactic medications are used to reduce the chance of aortic root dilation. Aortic regurgitation may require surgery. Marfan syndrome is associated with non-cardiac features, and the clinical criteria can be found on the American National Marfan Foundation website.

The ward doctor is requested to assess a 24-hour-old neonate, born at 35 weeks gestation to a healthy mother via an uncomplicated vaginal delivery. Upon examination, the neonate appears comfortable. Auscultation of the heart reveals a continuous 'machinery-like' murmur and a left-sided thrill. The apex beat is palpable and appears to be heaving. A widened pulse pressure is observed, but there is no visible cyanosis. An echocardiogram is performed and confirms the diagnosis while ruling out other cardiac issues.
What is the most appropriate course of action for management at this stage, given the likely diagnosis?Your Answer: Prostaglandin E1 given to the neonate
Correct Answer: Indomethacin given to the neonate
Explanation:The most likely diagnosis based on the findings is patent ductus arteriosus (PDA). To prompt duct closure in the majority of cases, the appropriate action is to administer indomethacin to the neonate in the postnatal period, not to the mother during the antenatal period. If another defect was present, prostaglandin E1 may be preferred to keep the duct open until after surgical repair. Referral for surgery is not necessary at this time. While percutaneous closure may be an option for older children, it is not suitable for neonates.
Patent ductus arteriosus is a type of congenital heart defect that is typically classified as ‘acyanotic’. However, if left untreated, it can eventually lead to late cyanosis in the lower extremities, which is known as differential cyanosis. This condition is caused by a connection between the pulmonary trunk and descending aorta that fails to close with the first breaths due to increased pulmonary flow that enhances prostaglandins clearance. Patent ductus arteriosus is more common in premature babies, those born at high altitude, or those whose mothers had rubella infection during the first trimester of pregnancy.
The features of patent ductus arteriosus include a left subclavicular thrill, a continuous ‘machinery’ murmur, a large volume, bounding, collapsing pulse, a wide pulse pressure, and a heaving apex beat. To manage this condition, indomethacin or ibuprofen is given to the neonate, which inhibits prostaglandin synthesis and closes the connection in the majority of cases. If patent ductus arteriosus is associated with another congenital heart defect that is amenable to surgery, then prostaglandin E1 is useful to keep the duct open until after surgical repair.

A 10-year-old boy is the shortest in his class, measuring only 125 cm. His parents are worried about his growth. His last three recorded heights have been between the 0.4th and 2nd centile. His mother is 160 cm tall and his father is 175 cm tall. He has no other health issues.
What could be the probable reason for his short stature?Your Answer: Familial short stature
Explanation:Familial Short Stature in Children
Children who have short parents and are otherwise healthy may have familial short stature. This means that their height and weight fall within the expected range based on their parents’ heights, and growth charts can be used to predict their adult height. In the case of a girl with familial short stature, her predicted adult height would be 154 cm, which falls within the mid-parental range of heights. Delayed puberty would cause a failure to gain height at the beginning of puberty and crossing of height centiles, while inadequate nutrition would cause crossing of both height and weight centiles. Low birth weight can also cause short stature in children, but in the absence of any other history, familial short stature is the most likely explanation. Precocious puberty, on the other hand, causes children to be tall for their age at the onset of puberty, not short.

Liam, a 13-year-old with learning difficulties, visits his GP clinic. Following a practice meeting, it is concluded that Liam does not possess the capacity to make decisions regarding his medical treatment. What principles should be prioritized when making decisions for Liam?
Your Answer: Consent may be given by one parent for the treatment that is in her best interests
Explanation:The GMC provides comprehensive guidance on obtaining consent from children. In cases where a child is incapable of giving consent, the agreement of one parent is adequate for treatment to be administered, provided it is in the child’s best interests. It is also crucial to involve Dawn in the decision-making process, despite her incapacity.
Guidelines for Obtaining Consent in Children
The General Medical Council has provided guidelines for obtaining consent in children. According to these guidelines, young people who are 16 years or older can be treated as adults and are presumed to have the capacity to make decisions. However, for children under the age of 16, their ability to understand what is involved determines whether they have the capacity to decide. If a competent child refuses treatment, a person with parental responsibility or the court may authorize investigation or treatment that is in the child’s best interests.
When it comes to providing contraceptives to patients under 16 years of age, the Fraser Guidelines must be followed. These guidelines state that the young person must understand the professional’s advice, cannot be persuaded to inform their parents, is likely to begin or continue having sexual intercourse with or without contraceptive treatment, and will suffer physical or mental health consequences without contraceptive treatment. Additionally, the young person’s best interests require them to receive contraceptive advice or treatment with or without parental consent.
Some doctors use the term Fraser competency when referring to contraception and Gillick competency when referring to general issues of consent in children. However, rumors that Victoria Gillick removed her permission to use her name or applied copyright have been debunked. It is important to note that in Scotland, those with parental responsibility cannot authorize procedures that a competent child has refused.

A 10-year-old girl presents to the Emergency Department with her mother, complaining of right iliac fossa pain for the past 2 days. She has no significant medical history, except for a recent cold and sore throat. She has had a high fever for the past 2 days and has lost her appetite, but denies any other symptoms. On examination, her temperature is 38.9 °C and her heart rate is 130 bpm. She has palpable and slightly tender submandibular and cervical lymph nodes on both sides. Her chest is clear, with transmitted sounds from the upper airways. Abdominal examination reveals marked tenderness in the right iliac fossa without guarding. A urine dipstick shows 2+ ketones and 1+ protein. Her FBC results are as follows: haemoglobin 145 g/l (normal range 135–175 g/l), WCC 14.3 × 109/l (normal range 4–11 × 109/l), and platelets 425 × 109/l (normal range 150–400 × 109/l). What is the most likely clinical diagnosis?
Your Answer: Mesenteric adenitis
Explanation:When a child presents with right iliac fossa pain, a previous and recent history of a viral upper respiratory tract infection, along with enlarged neck nodes and high temperature, may indicate mesenteric adenitis. This condition is caused by mesenteric lymphadenopathy and can cause abdominal pain. Appendicitis is another possible diagnosis, but it tends to present with a low-grade fever and involuntary muscle spasms in the abdominal wall. A urinary tract infection is unlikely if there are no nitrites or leukocytes on urine dipstick. Meckel’s diverticulitis is a rare complication of Meckel’s diverticulum and is difficult to diagnose without considering appendicitis. Retroperitoneal appendix abscess is another uncommon type of infection that presents with non-specific symptoms such as fever, back pain, and abdominal pain. High temperatures may also be present, but they usually fluctuate in abscesses.

Periventricular hemorrhage is a common condition in neonates that can lead to neurological damage. There are several possible causes of this condition, including vitamin K deficiency, folate deficiency from valproic acid treatment, congenital cytomegalovirus, congenital toxoplasmosis, and congenital herpes simplex virus.
Vitamin K deficiency is a natural occurrence in neonates as they do not have established gut bacteria that produce this vitamin. Vitamin K is essential for the production of clotting factors and anticoagulant proteins. Therefore, neonates born in hospitals are usually injected with vitamin K to prevent periventricular hemorrhage.
Folate deficiency from valproic acid treatment is a common cause of neural tube defects but does not lead to periventricular hemorrhage. Prenatal vitamins usually contain folate, which can prevent this deficiency.
Congenital cytomegalovirus and congenital toxoplasmosis can cause periventricular hemorrhage, but they are also accompanied by other congenital abnormalities, such as intracerebral calcifications.
Congenital herpes simplex virus can cause periventricular hemorrhage and neurological damage, but it also causes a diffuse vesicular rash and other symptoms.

Which one of the following statements regarding osteosarcoma is true?
Your Answer: More than 90% of children survive to adulthood
Explanation:Retinoblastoma is a prevalent type of eye cancer that is commonly found in children, with an average age of diagnosis at 18 months. It is caused by a loss of function of the retinoblastoma tumor suppressor gene on chromosome 13, which is inherited in an autosomal dominant pattern. About 10% of cases are hereditary. The most common presenting symptom is the absence of red-reflex, which is replaced by a white pupil (leukocoria). Other possible features include strabismus and visual problems.
When it comes to managing retinoblastoma, enucleation is not the only option. Depending on how advanced the tumor is, other treatment options include external beam radiation therapy, chemotherapy, and photocoagulation. The prognosis for retinoblastoma is excellent, with over 90% of patients surviving into adulthood.

A 31-year-old woman who is 39 weeks pregnant reaches out to you seeking details about the newborn hearing screening program. She expresses concerns about potential harm to her baby's ears and is uncertain about giving consent for the screening. What specific test is provided to all newborns as part of this screening program?
Your Answer: Automated otoacoustic emission test
Explanation:The automated otoacoustic emission test is the appropriate method for screening newborns for hearing problems. This test involves inserting a soft-tipped earpiece into the baby’s outer ear and emitting clicking sounds to detect a healthy cochlea. The auditory brainstem response test may be used if the baby does not pass the automated otoacoustic emission test. Play audiometry is only suitable for children between two and five years old, while pure tone audiometry is used for older children and adults and is not appropriate for newborns.
Hearing Tests for Children
Hearing tests are important for children to ensure that they are developing normally. There are several tests that may be performed on children of different ages. For newborns, an otoacoustic emission test is typically done as part of the Newborn Hearing Screening Programme. This test involves playing a computer-generated click through a small earpiece and checking for the presence of a soft echo, which indicates a healthy cochlea. If the results of this test are abnormal, an Auditory Brainstem Response test may be done.
For infants between 6-9 months, a Distraction test may be performed by a health visitor with the help of two trained staff members. For children between 18 months to 2.5 years, a Recognition of familiar objects test may be used, which involves using familiar objects like a teddy or cup and asking the child simple questions like where is the teddy? For children over 2.5 years, Performance testing and Speech discrimination tests may be used, such as the Kendall Toy test or McCormick Toy Test. Pure tone audiometry is typically done at school entry in most areas of the UK for children over 3 years old.
In addition to these tests, there is also a questionnaire for parents in the Personal Child Health Records called Can your baby hear you? It is important for parents to be aware of these tests and to have their child’s hearing checked regularly to ensure proper development.

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: 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.
