    Correct

    • As a junior doctor on the postnatal ward, you perform a newborn examination on a twelve-hour-old baby delivered vaginally. During the examination, you observe a scalp swelling that has poorly defined margins and crosses suture lines. The swelling is soft and pitted on pressure. The mother reports that the swelling has been present since birth. What is the probable diagnosis?

      Your Answer: Caput succedaneum

      Explanation:

      Scalp edema known as caput seccedaneum can be identified by its ability to extend beyond the suture lines during examination.

      Understanding Caput Succedaneum

      Caput succedaneum is a condition that refers to the swelling of the scalp at the top of the head, usually at the vertex. This swelling is caused by the mechanical trauma that occurs during delivery, particularly in prolonged deliveries or those that involve the use of vacuum delivery. The condition is characterized by soft, puffy swelling due to localized edema that crosses suture lines.

      Compared to cephalohaematoma, which is a collection of blood under the scalp, caput succedaneum is caused by edema. While cephalohaematoma is limited to a specific area and does not cross suture lines, caput succedaneum can affect a larger area and cross suture lines. Fortunately, no treatment is needed for caput succedaneum, as the swelling usually resolves on its own within a few days.

    Correct

    • At what point in the childhood immunisation schedule is the Meningitis B vaccine administered?

      Your Answer: 2, 4, and 12 months

      Explanation:

      The most prevalent cause of meningococcal disease in children in the UK is currently Meningitis B. In 2015, the Meningitis B vaccination was added to the NHS routine childhood immunisation schedule. It is administered at 2, 4, and 12 months of age, in conjunction with other immunisations in the schedule. If given at a different time, doses must be spaced at least 2 months apart. For children over one year old, only two doses are necessary.

      Meningitis B Vaccine Now Part of Routine NHS Immunisation

      Children in the UK have been vaccinated against meningococcus serotypes A and C for many years, leaving meningococcal B as the most common cause of bacterial meningitis in the country. However, a new vaccine called Bexsero has been developed to combat this strain. Initially, the Joint Committee on Vaccination and Immunisation (JCVI) rejected the use of Bexsero due to a cost-benefit analysis. However, the decision was eventually reversed, and the vaccine has been added to the routine NHS immunisation schedule.

      The vaccine is administered in three doses at 2 months, 4 months, and 12-13 months. Additionally, Bexsero will be available on the NHS for individuals at high risk of meningococcal disease, such as those with asplenia, splenic dysfunction, or complement disorder. This new vaccine is a significant step in protecting children and vulnerable individuals from meningitis B.

  • Question 3 - A 9-year-old girl comes to the GP with her father. Her father explains...

    Correct

    • A 9-year-old girl comes to the GP with her father. Her father explains that she is still experiencing bed-wetting almost every night. She has undergone thorough investigations in the past year for this issue and has no physical abnormalities to explain her enuresis. She is otherwise healthy and active.

      Her father has attempted to limit her fluid intake before bedtime, encourage regular and timely toileting, and wake her up during the night, but none of these methods have been successful.

      What is the most appropriate course of action to manage her enuresis?

      Your Answer: Enuresis alarm

      Explanation:

      Withholding fluids for 2 hours before bedtime is not recommended as part of enuresis management. While limiting fluid intake throughout the day and before bedtime, especially caffeinated drinks, is advised, completely withholding fluids is not recommended. Referring the patient for sleep studies is not the most appropriate management at this stage, although other conditions that can worsen enuresis, such as sleep-disordered breathing, should be considered. Desmopressin, an analogue of anti-diuretic hormone (ADH), is not indicated at this stage and is only used when general advice and enuresis alarm have failed. The primary goal of management is to achieve dry nights at follow-up.

      Nocturnal enuresis, or bedwetting, is when a child involuntarily urinates during the night. Most children achieve continence by the age of 3 or 4, so enuresis is defined as the involuntary discharge of urine in a child aged 5 or older without any underlying medical conditions. Enuresis can be primary, meaning the child has never achieved continence, or secondary, meaning the child has been dry for at least 6 months before.

      When managing bedwetting, it’s important to look for any underlying causes or triggers, such as constipation, diabetes mellitus, or recent onset UTIs. General advice includes monitoring fluid intake and encouraging regular toileting patterns, such as emptying the bladder before sleep. Reward systems, like star charts, can also be helpful, but should be given for agreed behavior rather than dry nights.

      The first-line treatment for bedwetting is an enuresis alarm, which has a high success rate. These alarms have sensor pads that detect wetness and wake the child up to use the toilet. If short-term control is needed, such as for sleepovers, or if the alarm is ineffective or not acceptable to the family, desmopressin may be prescribed. Overall, managing bedwetting involves identifying any underlying causes and implementing strategies to promote continence.

    Correct

    • A 7-year-old girl is seen in clinic for nocturnal enuresis. Despite her mother's attempts at using a reward system, there has been no improvement. What is the best initial approach to management?

      Your Answer: Enuresis alarm

      Explanation:

      If general advice has not been effective, an enuresis alarm is typically the initial treatment for nocturnal enuresis. It is not advisable to limit fluid intake. According to Clinical Knowledge Summaries, children should consume approximately eight drinks per day, evenly distributed throughout the day, with the last one consumed approximately one hour before bedtime.

      Nocturnal enuresis, or bedwetting, is when a child involuntarily urinates during the night. Most children achieve continence by the age of 3 or 4, so enuresis is defined as the involuntary discharge of urine in a child aged 5 or older without any underlying medical conditions. Enuresis can be primary, meaning the child has never achieved continence, or secondary, meaning the child has been dry for at least 6 months before.

    Correct

    • A 15-year-old girl comes to the clinic with concerns about not having started her periods yet. She is shorter than most girls her age. She has gone through adrenarche but has not yet experienced thelarche. Her mother and sister both began menstruating at age 12. The following are her blood test results:
      - FSH: 60 IU/L (normal range: 0-10)
      - LH: 40 IU/L (normal range: 0-16)
      - Oestradiol: 6.4 pmol/L (normal range: 73-407)
      - Thyroid stimulating hormone (TSH): 5.0 mU/L (normal range: 0.5-5.5)
      - Free thyroxine (T4): 12 pmol/L (normal range: 9.0-18)
      - Prolactin: 323 mIU/L (normal range: <700)

      Based on the patient's symptoms and test results, what is the most likely cause of her amenorrhoea?

      Your Answer: Turner's syndrome

      Explanation:

      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.

Unlike his older sibling who stopped bedwetting at the age of 4, this child still wets the bed at night. The mother is seeking advice on possible treatment options. What is the best course of action to manage this issue?

      Your Answer: Reassurance and advice on fluid intake, diet and toileting behaviour

      Explanation:

      Reassurance and advice are sufficient for managing nocturnal enuresis in children under 5 years of age. It is important to reassure mothers that bedwetting is still common at the age of 4.

      Nocturnal enuresis, or bedwetting, is when a child involuntarily urinates during the night. Most children achieve continence by the age of 3 or 4, so enuresis is defined as the involuntary discharge of urine in a child aged 5 or older without any underlying medical conditions. Enuresis can be primary, meaning the child has never achieved continence, or secondary, meaning the child has been dry for at least 6 months before.

    Correct

    • A 3-day old baby boy was delivered vaginally at full term after two cycles of In vitro fertilization (IVF). All antenatal scans were normal. Initially, he was feeding well, but over the past 24 hours, he has been feeding poorly, and his tummy has become larger. He has not had a bowel movement yet, and his mother has noticed multiple green/yellow vomits in the last few hours. There is no projectile vomiting. What is the probable diagnosis?

      Your Answer: Meconium ileus

      Explanation:

      The correct answer is meconium ileus, as the baby is showing signs of abdominal distension and bilious vomiting within the first 24-48 hours of life, and has not passed any meconium. While meconium ileus is more common in children with cystic fibrosis, the baby is too young to have been diagnosed with this condition yet, as the heel prick test is normally done at day 5.

      Duodenal atresia is less likely, as it typically presents in the first few hours of life and is often detected on antenatal scans, which were normal in this case.

      Necrotizing enterocolitis is unlikely, as it typically affects preterm babies at a few weeks of life, whereas this baby was born at term and is only 2 days old.

      Posseting, which is the act of bringing up small quantities of milk without pain or discomfort, is not associated with any pathology. However, in this scenario, the baby is vomiting green/yellow fluid, which is not typical of posseting. Therefore, posseting is an incorrect answer.

      Causes and Treatments for Bilious Vomiting in Neonates

      Bilious vomiting in neonates can be caused by various disorders, including duodenal atresia, malrotation with volvulus, jejunal/ileal atresia, meconium ileus, and necrotising enterocolitis. Duodenal atresia occurs in 1 in 5000 births and is more common in babies with Down syndrome. It typically presents a few hours after birth and can be diagnosed through an abdominal X-ray that shows a double bubble sign. Treatment involves duodenoduodenostomy. Malrotation with volvulus is usually caused by incomplete rotation during embryogenesis and presents between 3-7 days after birth. An upper GI contrast study or ultrasound can confirm the diagnosis, and treatment involves Ladd’s procedure. Jejunal/ileal atresia is caused by vascular insufficiency in utero and occurs in 1 in 3000 births. It presents within 24 hours of birth and can be diagnosed through an abdominal X-ray that shows air-fluid levels. Treatment involves laparotomy with primary resection and anastomosis. Meconium ileus occurs in 15-20% of babies with cystic fibrosis and presents in the first 24-48 hours of life with abdominal distension and bilious vomiting. Diagnosis involves an abdominal X-ray that shows air-fluid levels, and a sweat test can confirm cystic fibrosis. Treatment involves surgical decompression, and segmental resection may be necessary for serosal damage. Necrotising enterocolitis occurs in up to 2.4 per 1000 births, with increased risks in prematurity and inter-current illness. It typically presents in the second week of life and can be diagnosed through an abdominal X-ray that shows dilated bowel loops, pneumatosis, and portal venous air. Treatment involves conservative and supportive measures for non-perforated cases, while laparotomy and resection are necessary for perforated cases or ongoing clinical deterioration.

      Your Answer: 100%

      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.

      Your Answer: Reassurance to parents with general advice

      Explanation:

      Understanding and Managing Nocturnal Enuresis in Children

      Nocturnal enuresis, or bedwetting, is a common issue among children. While it can sometimes be caused by an underlying medical condition, such as a urinary tract infection or diabetes, in most cases it is simply a developmental issue that will resolve on its own over time.

      It is important to have a medical evaluation to rule out any underlying medical conditions, but once those have been ruled out, treatment is generally not recommended until the child is at least six years old. In the meantime, parents can use star charts and enuresis alarms to help motivate their child to stay dry at night.

      It is also important to consider any psychological issues that may be contributing to the problem. Parents should ask their child about their school performance, friendships, and home life, and try to speak to the child alone if possible to get a better understanding of any stressors that may be affecting them.

      There is no need for a referral for an ultrasound scan unless there is a suspicion of a structural abnormality. Desmopressin nasal spray can be prescribed for short-term relief, but oral imipramine is no longer recommended. Prophylactic antibiotics are also not indicated for nocturnal enuresis.

      Overall, parents should be reassured that bedwetting is a common issue that many children experience, and with time and patience, it will likely resolve on its own.

    Incorrect

    • As a foundation doctor on the postnatal ward, you conduct a newborn examination on a two-day-old baby girl. She was delivered normally and in good condition. During the hip examination, you observe that the left hip can be dislocated. What is the name of the examination you have conducted?

      Your Answer: Ortolani

      Correct Answer: Barlow

      Explanation:

      The Barlow manoeuvre is a technique used to try and dislocate a newborn’s femoral head. If successful, the Ortolani manoeuvre can then be used to relocate the dislocated femoral head. The Thomas test is not appropriate for neonates and is used to identify hip flexion contractures in older patients. The Denis Brown bar is an orthotic device used in conjunction with the Ponseti method to correct a fixed talipes.

      Developmental dysplasia of the hip (DDH) is a condition that affects 1-3% of newborns and is more common in females, firstborn children, and those with a positive family history or breech presentation. It used to be called congenital dislocation of the hip (CDH). DDH is more often found in the left hip and can be bilateral in 20% of cases. Screening for DDH is recommended for infants with certain risk factors, and all infants are screened using the Barlow and Ortolani tests at the newborn and six-week baby check. Clinical examination includes testing for leg length symmetry, restricted hip abduction, and knee level when hips and knees are flexed. Ultrasound is used to confirm the diagnosis if clinically suspected, but x-ray is the first line investigation for infants over 4.5 months. Management includes the use of a Pavlik harness for children under 4-5 months and surgery for older children with unstable hips.

    Correct

    • A 3-year-old boy is brought to the paediatric urology clinic due to recurrent urinary tract infections. A renal ultrasound revealed dilatation of the ureters. The boy's father remembers having a similar issue with a valve in his ureters during childhood, resulting in urine flowing back towards the kidneys. What is the most suitable test to assess the severity of the probable underlying cause?

      Your Answer: Micturating cystography

      Explanation:

      Vesicoureteral reflux (VUR) is a likely cause of recurrent urinary tract infections (UTIs) in children under 6 years old. The family history, age of the patient, and abnormal ultrasound findings suggest VUR as the underlying issue. To determine the severity of VUR, a voiding cystourethrogram (micturating cystography) is necessary. This test involves injecting dye into the bladder via a catheter and taking x-ray images while the child urinates. Early detection of VUR is crucial to prevent kidney scarring (reflux nephropathy).

      Bladder ultrasound is not an appropriate method for grading VUR severity. While ultrasound imaging of the urinary tract, including the kidneys, can be useful, it cannot grade VUR severity.

      A CT abdomen is not necessary and would expose the child to unnecessary radiation.

      A dimercaptosuccinic acid (DMSA) scan can assess renal parenchymal defects resulting from VUR and is typically performed within six months of an acute infection in children with recurrent UTIs. However, it cannot grade the severity of VUR.

      Understanding Vesicoureteric Reflux

      Vesicoureteric reflux (VUR) is a condition where urine flows back from the bladder into the ureter and kidney. This is a common urinary tract abnormality in children and can lead to urinary tract infections (UTIs). In fact, around 30% of children who present with a UTI have VUR. It is important to investigate for VUR in children following a UTI as around 35% of children develop renal scarring.

      The pathophysiology of VUR involves the ureters being displaced laterally, which causes a shortened intramural course of the ureter. This means that the vesicoureteric junction cannot function properly. VUR can present in different ways, such as hydronephrosis on ultrasound during the antenatal period, recurrent childhood UTIs, and reflux nephropathy, which is chronic pyelonephritis secondary to VUR. Renal scarring can also produce increased quantities of renin, which can cause hypertension.

      To diagnose VUR, a micturating cystourethrogram is usually performed. A DMSA scan may also be done to check for renal scarring. VUR is graded based on the severity of the condition, with Grade I being the mildest and Grade V being the most severe.

      Overall, understanding VUR is important in preventing complications such as UTIs and renal scarring. Early diagnosis and management can help improve outcomes for children with this condition.

    • A 14-year-old girl arrives at the clinic with her mother. She is asking for the combined oral contraceptive (COC) pill as she has recently started a relationship with a 19-year-old man whom she met at a local coffee shop, but they have not yet engaged in sexual activity. During the consultation, you discuss the age difference, but the mother assures you that she has met the boyfriend and believes he treats her daughter well. Both the girl and her mother insist that they do not want anyone else involved. What is the most appropriate course of action?

      Your Answer: Assess using Fraser guidelines + prescribe the COC

      Correct Answer: Immediately phone local child protection lead and refer to social services

      Explanation:

      According to the GMC guidelines, sexual intercourse with children below the age of 13 cannot be considered consensual, and therefore, any sexual activity would be classified as rape. In such cases, breaking confidentiality is mandatory.

      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.

      Your Answer: Fragile X syndrome

      Explanation:

      Although not a typical reason for macrocephaly, children diagnosed with Fragile X syndrome often exhibit an enlarged head size.

      Understanding Microcephaly: Causes and Definitions

      Microcephaly is a condition characterized by a smaller than average head circumference, with measurements falling below the 2nd percentile. While some cases may be attributed to normal variation or familial traits, other causes include congenital infections, perinatal brain injury, fetal alcohol syndrome, and syndromes such as Patau and craniosynostosis.

      In some cases, microcephaly may simply be a variation of normal development, with no underlying medical concerns. However, when it is caused by other factors, it can lead to developmental delays, intellectual disability, and other neurological issues.

      It is important to note that microcephaly is not a disease in and of itself, but rather a symptom of an underlying condition. As such, it is crucial to identify and address the root cause of microcephaly in order to provide appropriate treatment and support for affected individuals.

      On examination, he has moist mucous membranes, normal skin turgor, normal skin colour, normal peripheral pulses and a normal capillary refill time. His abdomen is soft and nontender and his peripheries are warm.
      What is the most appropriate initial management option for this patient?

      Your Answer: Oral rehydration solution (ORS)

      Explanation:

      Management of Dehydration in Children with Gastroenteritis

      Gastroenteritis is a common illness in children that can lead to dehydration if not managed properly. Oral rehydration solution (ORS) is the first-line treatment for children at increased risk of dehydration, including those who have vomited more than twice in the last 24 hours or have other risk factors such as age less than one year, low birth weight, or signs of malnutrition. However, if a child is clinically dehydrated and not responding to ORS, intravenous (IV) fluids may be necessary.

      It is important to encourage fluid intake in children with gastroenteritis, but carbonated drinks and fruit juices should be avoided as they can worsen diarrhea. If a child is unable to drink, an NG tube may be considered, but ORS should be attempted first. A bolus of IV fluids is only indicated in cases of suspected or confirmed shock.

      Overall, prompt recognition and management of dehydration in children with gastroenteritis can prevent serious complications and improve outcomes.

      Breastmilk jaundice is a common cause of jaundice in healthy, breastfed babies beyond two weeks of age. However, other potential causes should still be screened for. The exact mechanism of breastmilk jaundice is unknown, but breastfeeding should continue and bilirubin levels should be monitored. If levels are above the treatment line, phototherapy may be necessary. Jaundice can persist for up to 12 weeks in some cases. Cystic fibrosis is excluded as a diagnosis if the newborn blood-spot test is normal. Galactosaemia is unlikely if the baby has not shown symptoms such as difficulty feeding, vomiting, and faltering growth. ABO incompatibility typically presents within the first 24 hours of life, so it is unlikely if symptoms appear eight days after birth. Hypothyroidism is screened for in the newborn blood-spot test, and normal results exclude it as a diagnosis.

    Correct

    • A 6-year-old girl from a travelling community is brought to the Emergency Department with respiratory distress. Upon examination, she has a fever of 38.5ºC, stridor, and appears toxic. The medical team suspects acute epiglottitis. Which of the following pathogens is the most probable cause?

      Your Answer: Haemophilus influenzae

      Explanation:

      Incomplete immunisation may be a concern for patients belonging to travelling communities with regards to acute epiglottitis caused by Haemophilus influenzae type B.

      Acute epiglottitis is a rare but serious infection caused by Haemophilus influenzae type B. It is important to recognize and treat it promptly as it can lead to airway obstruction. Although it was once considered a disease of childhood, it is now more common in adults in the UK due to the immunization program. The incidence of epiglottitis has decreased since the introduction of the Hib vaccine. Symptoms include a rapid onset, high temperature, stridor, drooling of saliva, and a tripod position where the patient leans forward and extends their neck to breathe easier. Diagnosis is made by direct visualization, but x-rays may be done to rule out a foreign body.

      Immediate senior involvement is necessary, including those who can provide emergency airway support such as anaesthetics or ENT. Endotracheal intubation may be necessary to protect the airway. It is important not to examine the throat if epiglottitis is suspected due to the risk of acute airway obstruction. The diagnosis is made by direct visualization, but only senior staff who are able to intubate if necessary should perform this. Treatment includes oxygen and intravenous antibiotics.

    Incorrect

    • A 6-year-old boy is brought to the Emergency Department by his mother with complaints of right iliac fossa pain for the past two days. He has no previous medical history except for a cough and sore throat in the last week. He has had a high fever for the past two days and has lost his appetite but denies any other symptoms.
      On examination, his temperature is 38.9 °C, and his pulse is 130 beats per minute. Bilateral enlarged submandibular and cervical lymph nodes are palpable and slightly tender. Chest examination is clear, with transmitted sounds from the upper airways. Abdominal examination reveals marked tenderness in the right iliac fossa with no guarding.
      Urine dipstick reveals 2+ of ketones and 1+ of protein.
      Blood test results for his full blood count (FBC) are as follows:
      Investigation Result Normal value
      Haemoglobin (Hb) 145 g/l 135–175 g/l
      White cell count (WCC) 14.3 × 109/ 4.0–11.0 × 109/l
      Platelets (PLT) 425 × 109/l 150–400 × 109/l
      What is the most likely clinical diagnosis for this 6-year-old boy?

      Your Answer: Appendicitis

      Correct Answer: Mesenteric adenitis

      Explanation:

      Possible Diagnoses for a Child with Right Iliac Fossa Pain and High Temperature

      When a child presents with right iliac fossa pain and high temperature, several possible diagnoses should be considered. One of them is mesenteric adenitis, which is characterized by abdominal pain resulting from mesenteric lymphadenopathy and often accompanied by enlarged neck nodes and a recent history of viral upper respiratory tract infection. Appendicitis is another possibility, but it tends to present with a low-grade fever and peritoneal irritation that causes involuntary muscle spasm in the abdominal wall. Meckel’s diverticulitis, which is clinically indistinguishable from appendicitis, is an intra-operative or radiological diagnosis and can cause gastrointestinal bleeding, obstruction, inflammation, or umbilical discharge. Retroperitoneal appendix abscess is an uncommon type of infection that presents with fever, back pain, and abdominal pain, but it can also cause other symptoms such as gastrointestinal bleeding, poor wound healing, chest pain, general discomfort, urinary frequency, and haematuria. Finally, urinary tract infection (UTI) is unlikely if there are no nitrites or leukocytes on urine dipstick, but it can cause non-specific symptoms such as vomiting/diarrhoea, mild abdominal pain, dysuria, frequency, and enuresis, especially in infants.

    Correct

    • You are conducting the eight-week baby check on a healthy infant who was born at term. As part of health promotion, you are discussing ways to minimize the risk of Sudden Infant Death Syndrome (SIDS) with the mother. She is already aware of the significance of placing the baby on its back while sleeping and does not smoke. What is the most crucial additional risk factor for SIDS?

      Your Answer: Sleeping in the same bed as the baby

      Explanation:

      Studies have indicated that bed sharing is the most prominent risk factor for SIDS, followed by prone sleeping, parental smoking, hyperthermia and head covering, and prematurity.

      Understanding Sudden Infant Death Syndrome

      Sudden infant death syndrome (SIDS) is the leading cause of death in infants during their first year of life, with the highest incidence occurring at three months of age. There are several major risk factors associated with SIDS, including placing the baby to sleep on their stomach, parental smoking, prematurity, bed sharing, and hyperthermia or head covering. These risk factors are additive, meaning that the more risk factors present, the higher the likelihood of SIDS. Other risk factors include male sex, multiple births, lower social classes, maternal drug use, and an increased incidence during winter.

      However, there are also protective factors that can reduce the risk of SIDS. Breastfeeding, room sharing (but not bed sharing), and the use of pacifiers have been shown to be protective. In the event of a SIDS occurrence, it is important to screen siblings for potential sepsis and inborn errors of metabolism.

      Overall, understanding the risk factors and protective factors associated with SIDS can help parents and caregivers take steps to reduce the likelihood of this tragic event. By following safe sleep practices and promoting healthy habits, we can work towards reducing the incidence of SIDS.

    Correct

    • A 12-year-old Nigerian girl is brought to the GP clinic by her mother. She has been experiencing headaches, fatigue, and body aches for the past week. She has also been complaining of a sore throat and difficulty swallowing. This morning, her mother noticed swollen glands on both sides of her neck. The mother asks if her daughter can still attend school.
      What would be your advice to the mother?

      Your Answer: She should be kept off school for 5 days from the onset of swollen glands

      Explanation:

      If a child develops swollen glands due to mumps, they should stay away from school for 5 days starting from the day the swelling began. As the child’s swollen glands started one day ago, they should not attend school for the next 5 days. Waiting for a month is not necessary, but the child should not return to school until the 5-day exclusion period is over, even if the swelling has not completely resolved. The option suggesting waiting until all swellings have resolved before returning to school is incorrect.

      The Health Protection Agency has provided guidance on when children should be excluded from school due to infectious conditions. Some conditions, such as conjunctivitis, fifth disease, roseola, infectious mononucleosis, head lice, threadworms, and hand, foot and mouth, do not require exclusion. Scarlet fever requires exclusion for 24 hours after commencing antibiotics, while whooping cough requires exclusion for 2 days after commencing antibiotics or 21 days from onset of symptoms if no antibiotics are taken. Measles requires exclusion for 4 days from onset of rash, rubella for 5 days from onset of rash, and chickenpox until all lesions are crusted over. Mumps requires exclusion for 5 days from onset of swollen glands, while diarrhoea and vomiting require exclusion until symptoms have settled for 48 hours. Impetigo requires exclusion until lesions are crusted and healed, or for 48 hours after commencing antibiotic treatment, and scabies requires exclusion until treated. Influenza requires exclusion until the child has recovered. The official advice regarding school exclusion for chickenpox has varied, but the most recent guidance suggests that all lesions should be crusted over before children return to school.

    Correct

    • Fragile X is commonly associated with all of the following symptoms except?

      Your Answer: Small, firm testes

      Explanation:

      Fragile X Syndrome: A Genetic Disorder

      Fragile X syndrome is a genetic disorder caused by a trinucleotide repeat. It affects both males and females, but males are more severely affected. Common features in males include learning difficulties, large low set ears, long thin face, high arched palate, macroorchidism, hypotonia, and a higher likelihood of autism. Mitral valve prolapse is also a common feature. Females, who have one fragile chromosome and one normal X chromosome, may have a range of symptoms from normal to mild.

      Diagnosis of Fragile X syndrome can be made antenatally by chorionic villus sampling or amniocentesis. The number of CGG repeats can be analyzed using restriction endonuclease digestion and Southern blot analysis. Early diagnosis and intervention can help manage the symptoms of Fragile X syndrome and improve the quality of life for those affected.

    • A 12-year-old boy comes to the clinic with a history of headaches for the past 6 months. He reports experiencing these headaches once every few weeks, with each episode lasting for a day. Prior to the onset of the headache, he sees zig-zag lines. The headaches are typically on the right side of his head, accompanied by nausea and occasional vomiting. He finds some relief by sleeping in a dark, quiet room. Apart from this, he is healthy.
      What is the initial approach to managing his condition?

      Your Answer: Oral ibuprofen

      Explanation:

      The recommended initial treatment for paediatric migraines is ibuprofen. Sumatriptan nasal spray is only approved for use in children over the age of 12, and oral sumatriptan is not approved for those under 18. Codeine and oramorph are not recommended for treating migraines in children. Indomethacin is also not typically used for paediatric migraines.

      Understanding Headaches in Children

      Headaches are a common occurrence in children, with up to 50% of 7-year-olds and 80% of 15-year-olds experiencing at least one headache. Migraine without aura is the most common cause of primary headache in children, with a strong female preponderance after puberty. The International Headache Society has produced criteria for diagnosing pediatric migraine without aura, which includes headache attacks lasting 4-72 hours, with at least two of four specific features and accompanying symptoms such as nausea and vomiting.

      When it comes to acute management, ibuprofen is considered more effective than paracetamol for pediatric migraine. Triptans may be used in children over 12 years old, but follow-up is required, and only sumatriptan nasal spray is licensed for use in young people. However, oral triptans are not currently licensed for those under 18 years old, and side effects may include tingling, heat, and pressure sensations.

      Prophylaxis for pediatric migraine is limited, with no clear consensus guidelines. Pizotifen and propranolol are recommended as first-line preventatives, while valproate, topiramate, and amitriptyline are considered second-line preventatives. Tension-type headache is the second most common cause of headache in children, with diagnostic criteria including at least 10 previous headache episodes lasting from 30 minutes to 7 days, with specific pain characteristics and the absence of nausea or vomiting.

      In summary, headaches in children are common, and migraine without aura is the most common primary headache. Acute management includes ibuprofen and triptans, while prophylaxis is limited. Tension-type headache is also a common cause of headache in children. It is important to seek medical advice if headaches are frequent or severe, or if there are any concerning symptoms such as neurological deficits or changes in behavior.

    • A 9-year-old boy with asthma comes to the clinic with his mother, who is worried about his breathing problems. He has an oxygen saturation of 90%, his chest is slightly wheezy, but there is weak inspiratory effort, and his lips are pale.
      What is the probable classification of the acute asthma exacerbation?

      Your Answer: Life-threatening acute asthma

      Explanation:

      The child is experiencing life-threatening acute asthma, which is a medical emergency. This is defined as having any of the following features: SpO2 below 92%, peak expiratory flow below 33% of the best or predicted, silent chest, cyanosis, poor respiratory effort, hypotension, exhaustion, or confusion. Therefore, 999 should be called immediately. This is not moderate or mild acute asthma, nor is it acute severe asthma, as the child is showing signs of cyanosis. Acute severe asthma is defined as having any of the following: SpO2 between 33-50% of the best or predicted, inability to complete sentences in one breath or too breathless to talk or feed, heart rate above 125 beats/min (for ages over 5) or above 140 beats/min (for ages 1-5), or respiratory rate above 30 breaths/min (for ages over 5) or above 40 breaths/min (for ages 1-5).

    • A 5-year-old girl is brought to the emergency room by her father. She has been lethargic and feverish for the past 2 hours. While waiting to be seen, she becomes unconscious. A physician performs an urgent evaluation while the nurse contacts 911. The child is not breathing, so 5 rescue breaths are administered. As you enter the room, the physician cannot detect a pulse in the brachial or carotid artery. What is the best course of action?

      Your Answer: Start chest compressions/ventilations at a ratio of 15:2

      Explanation:

      The chest compressions to ventilations ratio should be 15:2 when two trained staff members are present.

      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.

      Your Answer: Mid-late diastolic murmur

      Correct Answer: Ejection systolic murmur

      Explanation:

      The ejection systolic murmur present in this patient is likely due to her Turner’s syndrome, which is associated with a bicuspid aortic valve. A continuous machinery murmur, late systolic murmur, and mid-late diastolic murmur are less likely causes, as they are associated with different conditions that are not commonly seen in patients with Turner’s syndrome.

      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.

He returns home and has been trying to pass stool with difficulty and pain. His father is worried because he now passes frequent small stools at home and is not sure what to do.

      What is the initial management option for this child?

      Your Answer: Macrogol daily

      Explanation:

      For a child experiencing functional constipation and showing signs of faecal impaction, the recommended first-line treatment is macrogols like Movicol. Docusate and senna are not the initial options but can be added if disimpaction is not achieved within two weeks. Lactulose is also a suitable osmotic laxative, but macrogols are more effective and therefore preferred as the first-line treatment. Liquid paraffin may be used as a lubricating laxative, but macrogols are more effective and should be used first. Psyllium husk is not appropriate for treating faecal impaction and may worsen the situation, so disimpaction should be achieved before increasing fibre intake.

      Understanding and Managing Constipation in Children

      Constipation is a common problem in children, with the frequency of bowel movements decreasing as they age. The National Institute for Health and Care Excellence (NICE) has provided guidelines for the diagnosis and management of constipation in children. A diagnosis of constipation is suggested by two or more symptoms, including infrequent bowel movements, hard stools, and associated distress or pain. Most cases of constipation in children are idiopathic, but other causes such as dehydration, low-fiber diet, and medication use should be considered and excluded.

      If a diagnosis of constipation is made, NICE recommends assessing for faecal impaction before starting treatment. Treatment for faecal impaction involves using polyethylene glycol 3350 + electrolytes (Movicol Paediatric Plain) as the first-line treatment, with the addition of a stimulant laxative if necessary. Maintenance therapy involves a similar regime, with adjustments to the starting dose and the addition of other laxatives if necessary.

      It is important to note that dietary interventions alone are not recommended as first-line treatment, although ensuring adequate fluid and fiber intake is important. Regular toileting and non-punitive behavioral interventions should also be considered. For infants, extra water, gentle abdominal massage, and bicycling the legs can be helpful for constipation. If these measures are not effective, lactulose can be added.

      In summary, constipation in children can be managed effectively with a combination of medication, dietary adjustments, and behavioral interventions. It is important to follow NICE guidelines and consider the individual needs of each child.

      Your Answer: Henoch-Schönlein purpura (HSP)

      Correct Answer: Immune thrombocytopaenic purpura (ITP)

      Explanation:

      ITP is a possible diagnosis for a child who presents with petechiae and no fever, while HUS and meningitis are unlikely. HSP may also be considered, but the child in the question has not experienced other symptoms of HSP. Non-accidental injury should also be considered as a differential for any petechial rash. However, ITP is more likely as it is often preceded by a viral illness and presents with isolated thrombocytopenia, causing the classic petechial rash. Blood results are needed to confirm the diagnosis.

      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.

    Correct

    • A 36-year-old woman has been diagnosed with pertussis. She came to the doctor's office after a child at her workplace daycare tested positive for whooping cough. She has been experiencing an on-and-off cough with occasional vomiting for the past 18 days. Assuming the patient has no allergies, what is the best course of treatment for this diagnosis?

      Your Answer: Azithromycin

      Explanation:

      Azithromycin or clarithromycin are recommended as first-line antibiotics for non-pregnant adults with whooping cough if the cough onset is within 21 days. Erythromycin can be used for pregnant adults. Co-amoxiclav and doxycycline are not recommended, and co-trimoxazole can be used off-label if macrolides are contraindicated or not tolerated. Antibiotics are preferred over supportive treatment within 21 days of presentation.

      Whooping Cough: Causes, Symptoms, Diagnosis, and Management

      Whooping cough, also known as pertussis, is a contagious disease caused by the bacterium Bordetella pertussis. It is commonly found in children, with around 1,000 cases reported annually in the UK. The disease is characterized by a persistent cough that can last up to 100 days, hence the name cough of 100 days.

      Infants are particularly vulnerable to whooping cough, which is why routine immunization is recommended at 2, 3, 4 months, and 3-5 years. However, neither infection nor immunization provides lifelong protection, and adolescents and adults may still develop the disease.

      Whooping cough has three phases: the catarrhal phase, the paroxysmal phase, and the convalescent phase. The catarrhal phase lasts around 1-2 weeks and presents symptoms similar to a viral upper respiratory tract infection. The paroxysmal phase is characterized by a severe cough that worsens at night and after feeding, and may be accompanied by vomiting and central cyanosis. The convalescent phase is when the cough subsides over weeks to months.

      To diagnose whooping cough, a person must have an acute cough that has lasted for 14 days or more without another apparent cause, and have one or more of the following features: paroxysmal cough, inspiratory whoop, post-tussive vomiting, or undiagnosed apnoeic attacks in young infants. A nasal swab culture for Bordetella pertussis is used to confirm the diagnosis, although PCR and serology are increasingly used.

      Infants under 6 months with suspected pertussis should be admitted, and in the UK, pertussis is a notifiable disease. An oral macrolide, such as clarithromycin, azithromycin, or erythromycin, is indicated if the onset of the cough is within the previous 21 days to eradicate the organism and reduce the spread. Household contacts should be offered antibiotic prophylaxis, although antibiotic therapy has not been shown to alter the course of the illness. School exclusion is recommended for 48 hours after commencing antibiotics or 21 days from onset of symptoms if no antibiotics are given.

      Complications of whooping cough include subconjunctival haemorrhage, pneumonia, bronchiectasis, and

    Correct

    • A 6-year-old boy is brought to the Emergency Department by his parents. He has been feeling unwell for 6 days with diarrhoea and is now lethargic and pale. Despite drinking enough fluids, he has not urinated in over 14 hours. The child has no medical history and has received all of his vaccinations. His symptoms began 3 days after he ate a chicken burger at a fair. During the examination, the doctor noticed multiple petechiae on his torso and limbs, and his feet were swollen. What is the likely diagnosis, and what is the organism responsible for this patient's illness?

      Your Answer: Escherichia coli

      Explanation:

      This child’s symptoms, including oliguria, peripheral edema, petechial bruising, and pallor, suggest the possibility of hemolytic uremic syndrome (HUS). HUS is often associated with diarrheal illnesses and is characterized by normocytic anemia, thrombocytopenia, and acute kidney injury. The most common cause of HUS is Shiga-toxin producing Escherichia coli, which can be contracted from undercooked meat, such as a chicken burger from a carnival. While Campylobacter jejuni is a common cause of acute diarrhea, it is not typically associated with HUS. Clostridium perfringens can cause acute diarrhea and vomiting but is not associated with HUS. Salmonella species can also cause diarrheal illnesses, but they are not a common cause of HUS. In this case, Escherichia coli is the most likely causative organism.

      Understanding Haemolytic Uraemic Syndrome

      Haemolytic uraemic syndrome (HUS) is a condition that primarily affects young children and is characterized by a triad of symptoms, including acute kidney injury, microangiopathic haemolytic anaemia, and thrombocytopenia. The majority of cases are secondary and caused by Shiga toxin-producing Escherichia coli (STEC) 0157:H7, also known as ‘verotoxigenic’ or ‘enterohaemorrhagic’. Other causes of HUS include pneumococcal infection, HIV, systemic lupus erythematosus, drugs, and cancer. Primary HUS, also known as ‘atypical’, is caused by complement dysregulation.

      To diagnose HUS, doctors may perform a full blood count to check for microangiopathic hemolytic anaemia and thrombocytopenia. A fragmented blood film may also be done to look for schistocytes and helmet cells. Additionally, a stool culture may be performed to check for evidence of STEC infection, and PCR for Shiga toxins may be done.

      Treatment for HUS is supportive and may include fluids, blood transfusion, and dialysis if required. Antibiotics are not recommended, despite the preceding diarrhoeal illness in many patients. Plasma exchange may be considered for severe cases of HUS not associated with diarrhoea, while eculizumab, a C5 inhibitor monoclonal antibody, has shown greater efficiency than plasma exchange alone in the treatment of adult atypical HUS.

      Overall, understanding the causes, symptoms, and management of HUS is crucial for healthcare professionals to provide appropriate care for patients with this condition.

      Your Answer: 6-8 months

      Explanation:

      The answer, which is typically 7-8 months, differs slightly from the 6 months stated in the MRCPCH Development Guide.

      Gross Motor Developmental Milestones

      Gross motor skills refer to the ability to use large muscles in the body for activities such as crawling, walking, running, and jumping. These skills are essential for a child’s physical development and are achieved through a series of developmental milestones.
      At 3 months, a baby should have little or no head lag when pulled to sit and should have good head control when lying on their abdomen. By 6 months, they should be able to lift and grasp their feet when lying on their back, pull themselves to a sitting position, and roll from front to back. At 9 months, they should be able to pull themselves to a standing position and crawl. By 12 months, they should be able to cruise and walk with one hand held. At 18 months, they should be able to walk unsupported and squat to pick up a toy. By 2 years, they should be able to run and walk up and down stairs holding onto a rail. At 3 years, they should be able to ride a tricycle using pedals and walk up stairs without holding onto a rail. By 4 years, they should be able to hop on one leg.

      It is important to note that while the majority of children crawl on all fours before walking, some children may bottom-shuffle, which is a normal variant that runs in families. These milestones serve as a guide for parents and healthcare professionals to monitor a child’s physical development and identify any potential delays or concerns.

    Incorrect

    • A 10-year-old boy is brought to surgery as his father is worried about his weight. This has been a concern for more than three years and dad believes it is affecting his son's performance in school. What is the best way to determine the extent of his obesity?

      Your Answer: Body mass index

      Correct Answer: Body mass index percentile adjusted to age and gender

      Explanation:

      Understanding Obesity in Children

      Childhood obesity is a complex issue that requires careful assessment and management. Unlike adults, defining obesity in children is more challenging as body mass index (BMI) varies with age. To accurately assess BMI, percentile charts are needed. According to recent guidelines by the National Institute for Health and Care Excellence (NICE), the UK 1990 BMI charts should be used to provide age- and gender-specific information.

      NICE recommends tailored clinical intervention if BMI is at the 91st centile or above. If BMI is at the 98th centile or above, assessing for comorbidities is necessary. Lifestyle factors are the most common cause of obesity in childhood. However, other factors such as growth hormone deficiency, hypothyroidism, Down’s syndrome, Cushing’s syndrome, and Prader-Willi syndrome can also contribute to obesity in children.

      Obesity in children can lead to various consequences, including orthopaedic problems such as slipped upper femoral epiphyses and Blount’s disease, musculoskeletal pains, psychological consequences like poor self-esteem and bullying, sleep apnoea, and benign intracranial hypertension. Moreover, obesity in childhood can increase the risk of developing type 2 diabetes mellitus, hypertension, and ischaemic heart disease in the long run. Therefore, it is crucial to identify and manage obesity in children to prevent these adverse outcomes.
