Which one of the following statements regarding Perthes disease is incorrect?
Your Answer: Twice as common in girls
Explanation:Understanding Perthes’ Disease
Perthes’ disease is a degenerative condition that affects the hip joints of children, typically between the ages of 4-8 years. It is caused by a lack of blood supply to the femoral head, which leads to bone infarction and avascular necrosis. This condition is more common in boys, with around 10% of cases being bilateral. The symptoms of Perthes’ disease include hip pain, stiffness, reduced range of hip movement, and a limp. Early changes can be seen on an x-ray, such as widening of the joint space, while later changes include decreased femoral head size and flattening.
To diagnose Perthes’ disease, a plain x-ray is usually sufficient. However, if symptoms persist and the x-ray is normal, a technetium bone scan or magnetic resonance imaging may be necessary. If left untreated, Perthes’ disease can lead to complications such as osteoarthritis and premature fusion of the growth plates.
The severity of Perthes’ disease is classified using the Catterall staging system, which ranges from stage 1 (clinical and histological features only) to stage 4 (loss of acetabular integrity). Treatment options include keeping the femoral head within the acetabulum using a cast or braces, observation for children under 6 years old, and surgical management for older children with severe deformities. The prognosis for Perthes’ disease is generally good, with most cases resolving with conservative management. Early diagnosis is key to improving outcomes.

A 4-year-old patient presents with recurrent chest infections and green sputum production. Upon examination, a chest x-ray reveals ring shadows and bronchial wall thickening in both lung bases. What is the probable diagnosis?
Your Answer: Tuberculosis
Correct Answer: Bronchiectasis
Explanation:Recurrent Chest Infections and Bronchiectasis: A Possible Sign of Cystic Fibrosis
Patients who have a history of recurrent chest infections and x-ray appearances that suggest bronchiectasis may be showing signs of cystic fibrosis. Bronchiectasis is a condition where the airways in the lungs become damaged and widened, leading to a build-up of mucous and bacteria. This can cause recurrent chest infections, which can be difficult to treat. Cystic fibrosis is a genetic condition that affects the production of mucous, leading to thick and sticky secretions that can block the airways and cause infections.
If a patient is showing signs of bronchiectasis, it is important to consider cystic fibrosis as a possible cause. Early diagnosis and treatment of cystic fibrosis can help to manage symptoms and prevent complications. Testing for cystic fibrosis may involve a sweat test, genetic testing, or other diagnostic tests. Treatment may include medications to help clear mucous from the airways, antibiotics to treat infections, and other therapies to manage symptoms.

You are a junior doctor in paediatrics. You are called to attend an emergency Caesarean section for a baby at 32 weeks’ gestation due to fetal distress. The baby is delivered and does not cry immediately. The cord is cut, and the baby is dried and placed on the Resuscitaire®. There is no spontaneous respiratory effort from the baby who is pale and floppy, with a heart rate of 30 bpm.
When would it be appropriate to start chest compressions in a premature neonate?Your Answer: After five inflation breaths if the baby is not spontaneously breathing
Correct Answer:
Explanation:Neonatal Resuscitation Guidelines for Heart Rate and Ventilation
In neonatal resuscitation, it is important to follow guidelines for heart rate and ventilation to ensure the best possible outcome for the baby. Here are the guidelines for different scenarios:
– After a total of ten inflation breaths and 30 seconds of effective ventilation breaths if the baby’s heart rate is < 60 bpm: Chest compressions are indicated at a ratio of 3:1 (compression:ventilation). The heart rate should be checked every 30 seconds. If the heart rate is not detectable or very slow (<60), consider venous access and drugs.
– After ten inflation breaths if the baby’s heart rate is < 120 bpm: Give 30 seconds of effective ventilation breaths before starting compressions if the heart rate is < 60 bpm.
– After five inflation breaths if the baby is not spontaneously breathing: Ventilate for 30 seconds before starting compressions, unless there is an underlying cardiac cause for the cardiorespiratory arrest.
– After ten inflation breaths and two minutes of effective ventilation breaths if the baby’s heart rate is < 60 bpm: This scenario is not applicable as compressions should have been started after the initial 30 seconds of ventilation.
– Before any inflation breaths if the baby’s heart rate is < 60 bpm: Give 30 seconds of effective ventilation breaths before starting compressions if ten inflation breaths are not successful and the heart rate is still < 60 bpm. -

A 1-day-old child is found to have absent femoral pulses and a systolic ejection murmur over the left side of their chest and back upon their routine examination. Their brachial pulses are strong. They appear pale and are tachypnoeic. They have not managed to eat much solid food, as they become distressed.
Which of the following statements about their condition is true?Your Answer: If diagnosed antenatally, the baby should be given a prostaglandin inhibitor after birth to encourage closure of the ductus arteriosus
Correct Answer: May be treated by balloon angioplasty with or without stenting
Explanation:Coarctation of the Aorta: Diagnosis and Treatment Options
Coarctation of the aorta is a congenital condition that causes narrowing of the aorta, most commonly at the site of insertion of the ductus arteriosus. Diagnosis can be made antenatally or after birth upon newborn examination. Treatment options include surgical repair or balloon angioplasty and/or stenting. If diagnosed antenatally, prostaglandin is given to encourage the ductus arteriosus to remain patent until repair is performed. Less severe cases can present in older children with symptoms such as leg pain, tiredness, dizzy spells, or an incidental finding of a murmur. Following repair, there are rarely any long-term complications, but re-coarctation can occur. Balloon angioplasty, with or without stenting, can be used in some circumstances, rather than surgical reconstruction. It is important to monitor for hypertension and/or premature cardiovascular or cerebrovascular disease in adults with a previous history of coarctation of the aorta.

Should all infants undergo hearing screening by their health visitor as part of the 'Infant Hearing Screening Programme'? And if the results are abnormal, what is the next hearing test they will have?
Your Answer: Otoacoustic emission test at 6-9 months old
Correct Answer: Auditory Brainstem Response test as a newborn/infant
Explanation:When a newborn baby’s hearing test at birth shows an abnormal result, they are recommended to undergo an auditory brainstem response test as a newborn or infant. Prior to being discharged from the hospital, all newborns should have an acoustic emission test, which involves placing a soft earpiece in the baby’s ear and playing quiet clicking sounds to detect inner ear responses. If this test yields abnormal results, the auditory brainstem response test is conducted using three sensors placed on the baby’s head and neck, along with soft headphones to play sounds and analyze the brain and hearing nerve responses. At 6-9 months of age, a distraction test is performed, and most areas in the UK conduct pure tone audiometry at school entry.
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 neighbor has a grandchild diagnosed with tetralogy of Fallot and asks you about this condition.
Which of the following is a characteristic of this condition?Your Answer: Aortic stenosis
Correct Answer: Right ventricular hypertrophy
Explanation:Common Congenital Heart Defects and Acquired Valvular Defects
Congenital heart defects are present at birth and can affect the structure and function of the heart. Tetralogy of Fallot is a common congenital heart defect that includes right ventricular hypertrophy, ventricular septal defect, right-sided outflow tract obstruction, and overriding aorta. On the other hand, patent ductus arteriosus (PDA) and atrial septal defect (ASD) are not part of the tetralogy of Fallot but are commonly occurring congenital heart defects.
PDA is characterized by a persistent communication between the descending thoracic aorta and the pulmonary artery, while ASD is characterized by a defect in the interatrial septum, allowing shunting of blood from left to right. If left untreated, patients with a large PDA are at risk of developing Eisenmenger syndrome in later life.
Acquired valvular defects, on the other hand, are not present at birth but develop over time. Aortic stenosis is an acquired valvular defect that results from progressive narrowing of the aortic valve area over several years. Tricuspid stenosis, which is caused by obstruction of the tricuspid valve, can be a result of several conditions, including rheumatic heart disease, congenital abnormalities, active infective endocarditis, and carcinoid tumors.

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: Auditory brainstem response test
Correct 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.

A 13-year-old boy was hospitalized due to a two-week history of high-grade fever and bleeding gums. Upon examination of his peripheral blood, multiple blasts were observed, some of which displayed Auer rods. Which congenital condition is most strongly linked to this presentation?
Your Answer: Gardner syndrome
Correct Answer: Trisomy 21 (Down syndrome)
Explanation:Congenital syndromes associated with acute myeloblastic leukemia
Acute myeloblastic leukemia (AML) can be associated with various congenital syndromes, including severe congenital neutropenia (Kostmann syndrome), Bloom syndrome, Fanconi anemia, Diamond-Blackfan syndrome, neurofibromatosis type 1, and Li Fraumeni syndrome. However, Gardner syndrome, or familial colorectal polyposis, is not linked to AML. Trisomy 18 (Edward syndrome) is a chromosomal abnormality that has a poor prognosis but is not typically associated with AML. Klinefelter syndrome, a genetic disorder characterized by an extra X chromosome in males, may increase the risk of breast cancer and germ cell tumors, but the evidence for an association with AML is inconclusive. Haemophilia, a bleeding disorder caused by a deficiency in clotting factors, does not predispose to AML or mucosal bleeding.

A 6-year-old girl has been referred to the enuresis clinic by her pediatrician due to ongoing bedwetting. Her mother has expressed concern as the girl has never had a dry night. The pediatrician has provided advice on diet, fluid intake, and toileting habits, but the bedwetting persists despite the use of a reward system. The mother has contacted the enuresis clinic for further intervention. What is the likely intervention that will be provided?
Your Answer: Desmopressin
Correct Answer: Enuresis alarm
Explanation:When a child experiences nocturnal enuresis, an enuresis alarm is typically the first option if general advice has not been effective. According to NICE guidelines, this is the primary approach. It may be worthwhile to consider a more appealing reward system to motivate the child, as they may not be incentivized if the prize is not deemed valuable. However, it is assumed that the mother can adequately motivate their child, so this may not be the chosen route for the clinic. If the initial intervention is unsuccessful, it is unlikely that repeating it will yield different results. If the enuresis alarm is not effective, pharmacological interventions such as desmopressin, oxybutynin, and unlicensed tolterodine may be considered, with desmopressin being the usual choice.
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.

A 7-year-old boy is brought to his pediatrician by his father with a 2-week history of cough. His father reports that he had a few days of cold symptoms about 3 weeks ago, just before the cough started. He says that his son coughs frequently, sometimes leading to vomiting, and has noticed a 'whooping' sound when he inhales after a coughing episode. All vital signs are normal.
What is the recommended treatment for the probable diagnosis?Your Answer: Prescribe oral co-amoxiclav
Correct Answer: Prescribe oral clarithromycin
Explanation:If a patient presents with whooping cough within 21 days of the onset of cough, they should be prescribed either azithromycin or clarithromycin. In this case, the correct option is to prescribe oral clarithromycin. Hospital admission for IV antibiotics is not necessary as the patient is stable. If the patient had presented after three weeks, advice would be the appropriate course of action. Oral co-amoxiclav and oral doxycycline are not recommended treatments for whooping cough.
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

A teenager attends the GP with his mother who is concerned about his height. The GP charts the teenager's height on a growth chart and finds him to be in the 5th percentile. At birth, he was in the 50th percentile. However, the teenager's developmental milestones are normal, and he appears to be content with himself. What is the most appropriate next step in managing this teenager?
Your Answer: Review the child in the GP clinic in 2 years
Correct Answer: Make a referral to the the paediatric outpatients clinic
Explanation:A paediatrician should review children who fall below the 0.4th centile for height. Referral is the appropriate course of action as it is not an urgent matter. While waiting for the review, it is advisable to conduct thyroid function tests and insulin-like growth factor tests on the child.
Understanding Growth and Factors Affecting It
Growth is a significant aspect that distinguishes children from adults. It occurs in three stages: infancy, childhood, and puberty. Several factors affect fetal growth, including environmental, placental, hormonal, and genetic factors. Maternal nutrition and uterine capacity are the most crucial environmental factors that affect fetal growth.
During infancy, nutrition and insulin are the primary drivers of growth. Insulin plays a significant role in fetal growth, as high levels of insulin in a mother with poorly controlled diabetes can result in hypoglycemia and macrosomia in the baby. In childhood, growth hormone and thyroxine drive growth, while in puberty, growth hormone and sex steroids are the primary drivers. Genetic factors are the most important determinant of final adult height.
It is essential to monitor growth regularly to ensure that children are growing at a healthy rate. Infants aged 0-1 years should have at least five weight recordings, while children aged 1-2 years should have at least three weight recordings. Children older than two years should have annual weight recordings. Children below the 2nd centile for height should be reviewed by their GP, while those below the 0.4th centile for height should be reviewed by a paediatrician. Understanding growth and the factors that affect it is crucial for ensuring healthy development in children.

A mother brings her 8-week-old baby to the GP clinic for their routine 7-week check-up. The baby appears happy and responsive during the assessment. During the examination, you observe weak femoral pulses on both sides. The rest of the examination is normal.
What is the most suitable course of action to take?Your Answer: Advise the mother these can be normal findings, fill in the red book and safety net
Correct Answer: Same day discussion with paediatrics
Explanation:If a baby’s femoral pulses are absent or weak during their 6-8 week check, it is important to discuss this immediately with paediatrics. Any signs of a critical or major congenital heart abnormality should also be seen urgently by a specialist. Advising the mother that these findings are normal would be inappropriate, as they are abnormal. While safety netting is important, the child should still be seen urgently by the appropriate specialist. Taking the child to the emergency department is not the best option, as they may not be equipped to deal with this issue and will likely refer to the paediatrics team themselves. Referring routinely to paediatrics or making an appointment in 2 weeks would waste valuable time in a potentially unwell child who needs urgent referral.
Congenital heart disease can be categorized into two types: acyanotic and cyanotic. Acyanotic heart diseases are more common and include ventricular septal defects (VSD), atrial septal defect (ASD), patent ductus arteriosus (PDA), coarctation of the aorta, and aortic valve stenosis. VSD is the most common acyanotic heart disease, accounting for 30% of cases. ASDs are less common than VSDs, but they are more frequently diagnosed in adult patients as they tend to present later. On the other hand, cyanotic heart diseases are less common and include tetralogy of Fallot, transposition of the great arteries (TGA), and tricuspid atresia. Fallot’s is more common than TGA, but TGA is the more common lesion at birth as patients with Fallot’s generally present at around 1-2 months. The presence of cyanosis in pulmonary valve stenosis depends on the severity and any other coexistent defects.

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: Anorectal Pull through
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.

A mother presents with her 3-month-old baby boy to ask advice about his failed newborn hearing screening. Further tests were normal; however, she has been advised to seek medical advice if she has any concerns about his hearing in the future. Which one of the following would warrant referral for a further hearing test?
Your Answer: Not responding to his own name by the age of six months old
Correct Answer: Not babbling or imitating sounds by the age of nine months old
Explanation:Developmental Milestones for Language Acquisition in Children
Language acquisition is an important developmental milestone in children. Here are some key markers to look out for:
– Not babbling or imitating sounds by the age of nine months old: If a baby is not babbling or imitating sounds by this age, it could be a sign of a social, cognitive, speech, or hearing problem. A full developmental assessment would be necessary to ensure there are no other areas of delay.
– Putting two words together by the age of 18 months old: By this age, a child should be using 50+ words and be able to put two words together. If not, a full developmental assessment would be necessary to ensure there are no other areas of delay.
– More than 200 spoken words by the age of two years: A 30-month-old child should be using 200+ words. If not, a full developmental assessment would be necessary to ensure there are no other areas of delay.
– Not responding to his own name by the age of six months old: By the age of one year, a child should respond to their own name. If not, a full developmental assessment would be necessary to ensure there are no other areas of delay.
– Speaking 6-20 words by the age of one year: By the age of one, a child should be using 6-20 words. If not, a full developmental assessment would be necessary to ensure there are no other areas of delay.
It is important to monitor a child’s language development and seek professional help if there are any concerns. Early intervention can make a significant difference in a child’s language acquisition and overall development.

An 18-year-old girl visits her GP with worries about not having started her menstrual cycle yet. Apart from that, she feels healthy. During the examination, she appears to be of average height and has developed breasts, but has minimal pubic hair growth. The doctor can feel two lumps in her groin area upon examination of her abdomen. Her external genitalia seem normal. What is the probable diagnosis?
Your Answer: Turner's syndrome
Correct Answer: Androgen insensitivity syndrome
Explanation:The patient’s presentation is consistent with androgen insensitivity, which is a genetic condition where individuals with XY chromosomes have female physical characteristics due to a lack of testosterone receptors in their tissues. This disorder is X-linked and often results in undescended testes. Congenital adrenal hyperplasia is unlikely as it typically causes early puberty and virilization, while Kallmann syndrome does not explain the presence of groin masses. Polycystic ovarian syndrome usually results in secondary amenorrhea or oligomenorrhea and is accompanied by other symptoms such as acne and hirsutism. Turner’s syndrome, which causes primary amenorrhea, is characterized by short stature, webbed neck, heart defects, and abnormal breast development, and does not involve undescended testes.
Disorders of sex hormones can have various effects on the body, as shown in the table below. Primary hypogonadism, also known as Klinefelter’s syndrome, is characterized by high levels of LH and low levels of testosterone. Patients with this disorder often have small, firm testes, lack secondary sexual characteristics, and are infertile. They may also experience gynaecomastia and have an increased risk of breast cancer. Diagnosis is made through chromosomal analysis.
Hypogonadotrophic hypogonadism, or Kallmann syndrome, is another cause of delayed puberty. It is typically inherited as an X-linked recessive trait and is caused by the failure of GnRH-secreting neurons to migrate to the hypothalamus. Patients with Kallmann syndrome may have hypogonadism, cryptorchidism, and anosmia. Sex hormone levels are low, and LH and FSH levels are inappropriately low or normal. Cleft lip/palate and visual/hearing defects may also be present.
Androgen insensitivity syndrome is an X-linked recessive condition that causes end-organ resistance to testosterone, resulting in genotypically male children (46XY) having a female phenotype. Complete androgen insensitivity syndrome is the new term for testicular feminisation syndrome. Patients with this disorder may experience primary amenorrhoea, undescended testes causing groin swellings, and breast development due to the conversion of testosterone to oestradiol. Diagnosis is made through a buccal smear or chromosomal analysis to reveal a 46XY genotype. Management includes counseling to raise the child as female, bilateral orchidectomy due to an increased risk of testicular cancer from undescended testes, and oestrogen therapy.

A 4-year-old girl with cerebral palsy comes to the GP with her father for a check-up. Upon examination, she has a delay in her overall development. She is not yet able to walk or crawl, but she can use her fingers to pick up objects and is happily playing with toys during the visit. She can say a few words, such as mom and dad. During the examination, you notice some bruises on her abdomen, left elbow, and right forearm. Her father explains that these bruises are due to her clumsiness and he is concerned that she will continue to hurt herself. He mentions that her mother had a similar condition that required oral steroids and wonders if his daughter has developed the same condition.
What is the next step in managing this patient?Your Answer: Coagulation screen and coagulopathy testing
Correct Answer: Same-day paediatric assessment
Explanation:Immediate paediatric assessment is necessary for a non-mobile infant with multiple bruises, as this could indicate non-accidental injury. Bruising near the trunk, cheeks, ears, or buttocks should also be considered red flags. Coagulation screen and coagulopathy testing may be performed later, but the priority is to assess for potential abuse. Oral prednisolone is not first-line for children with immune thrombocytopenia (ITP) and reassurance and discharge are not appropriate in this situation.
Recognizing Child Abuse: Signs and Symptoms
Child abuse is a serious issue that can have long-lasting effects on a child’s physical and emotional well-being. It is important to be able to recognize the signs and symptoms of child abuse in order to intervene and protect the child. One possible indicator of abuse is when a child discloses abuse themselves. However, there are other factors that may point towards abuse, such as an inconsistent story with injuries, repeated visits to A&E departments, delayed presentation, and a frightened, withdrawn appearance known as frozen watchfulness.
Physical presentations of child abuse can also be a sign of abuse. These may include bruising, fractures (especially metaphyseal, posterior rib fractures, or multiple fractures at different stages of healing), torn frenulum (such as from forcing a bottle into a child’s mouth), burns or scalds, failure to thrive, and sexually transmitted infections like Chlamydia, gonorrhoeae, and Trichomonas. It is important to be aware of these signs and symptoms and to report any concerns to the appropriate authorities to ensure the safety and well-being of the child.

A mother gives birth to her first baby. The baby begins vomiting persistently during the fourth week of life. The paediatrician performs a physical examination of the baby and feels a small mass about the size of an olive in the epigastrium.
Which of the following is this child likely to exhibit?Your Answer: Pancreas divisum
Correct Answer: Pyloric stenosis
Explanation:Pediatric Gastrointestinal Disorders: Pyloric Stenosis, Pancreas Divisum, Biliary Stenosis, and Duodenal Atresia
Pyloric Stenosis: A newborn presenting with non-bilious vomiting during the third week of life and an ‘olive’ in the epigastrum on physical examination is indicative of pyloric stenosis. This condition occurs when the pylorus, the region of the stomach that serves as the junction between the stomach and the duodenum, becomes obstructed, preventing duodenal material from traveling to more proximal structures.
Pancreas Divisum: Pancreas divisum is a condition in which the ventral and dorsal anlage of the pancreas fail to fuse during embryology, leading to pancreatitis and pancreatic insufficiency. This occurs because the pancreatic duct fails to form, forcing pancreatic secretions through two smaller dorsal and ventral ducts that cannot support the required flow of secretions. Pancreatic juices accumulate and dilate the smaller ducts, leading to pancreatitis.
Biliary Stenosis: Biliary stenosis can lead to digestion problems, as the narrow biliary tree prevents bile from reaching the duodenum. Patients with this condition may experience cramping pain when ingesting fatty foods, and fat-soluble vitamin deficiency can develop.
Duodenal Atresia: Duodenal atresia refers to a blind-ended duodenum, which causes bilious vomiting shortly after beginning to feed. This condition is associated with trisomy 21, but there is no evidence of trisomy 21 in this scenario, and the vomiting has begun after the third week of life.
Overall, these pediatric gastrointestinal disorders have distinct presentations and require different diagnostic approaches. It is important for healthcare providers to consider all possible conditions when evaluating a patient with gastrointestinal symptoms.

Question 18
Incorrect

A 6-month-old girl is brought to the emergency department with a persistent dry cough and difficulty feeding for the past week. Her medical history is unremarkable, but she had a mild fever and coryzal symptoms a week ago. On examination, bilateral wheezing is heard with a respiratory rate of 58/min. However, there are no signs of increased work of breathing and chest expansion is symmetrical. The infant's temperature is 37.6ºC and oxygen saturation is 99% on room air. What is the most appropriate next step in management?
Your Answer: Antibiotics after doing a chest X-ray
Correct Answer: Continue observation then discharge with safety-netting advice
Explanation:Bronchiolitis is typically caused by a virus, so antibiotics should not be immediately prescribed. However, if there are signs of secondary bacterial pneumonia or respiratory failure, antibiotics may be considered. It is incorrect to prescribe antibiotics based on a chest X-ray, as this is not a reliable method for determining further treatment. Bronchodilators, like salbutamol inhalers, are not helpful in treating bronchiolitis, especially in children under 1 year old who are unlikely to have viral-induced wheezing.
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 32-year-old woman gives birth to a 37-week gestational age male neonate. Within 6 hours after delivery, the neonate shows signs of excessive respiratory efforts and tachypnoea. There is grunting and intercostal retraction. A chest X-ray reveals bilateral pulmonary oedema with a ground-glass appearance. What antenatal examination findings are most likely to have been observed in the mother?
Your Answer: Elevated titres of anti-nuclear and anti-SSA antibodies
Correct Answer: Fasting blood sugar of 14.0 mmol/l
Explanation:The neonate in question has a fasting blood sugar level of 14.0 mmol/l and is suffering from neonatal respiratory distress syndrome (NRDS). This is a common condition in premature infants, and those born to diabetic mothers are at an increased risk due to delayed lung maturation. An elevated total thyroxine concentration is a normal response to pregnancy and is not related to NRDS. Maternal hypocalcaemia also has no relation to NRDS. A positive indirect Coombs’ test indicates a risk of Rh isoimmunisation in the fetus, which can lead to complications such as erythroblastosis fetalis and jaundice, but is not directly related to NRDS. Elevated titres of anti-nuclear and anti-SSA antibodies are associated with maternal systemic lupus erythematosus and fetal conduction heart block, but again, this is not directly related to NRDS unless it leads to preterm birth. Overall, prematurity and maternal diabetes are the major risk factors for NRDS.

You are working at a Saturday morning clinic and a mother brings in her 10-year-old daughter who has developed new pustular, honey-coloured crusted lesions over her chin. She is systemically well with all observations in the normal range and no evidence of lymphadenopathy on examination. She has no allergies to any medications and is normally fit and well.
You diagnose localised non-bullous impetigo.
The daughter is due to go on a school trip to the Natural History Museum in London the following day and is extremely excited about this. The mother asks if she is allowed to go on this school trip.
What is your management plan?Your Answer: Prescribe topical fusidic acid 2% and reassure them that he can go on the school trip as soon as he has started using it
Correct Answer: Prescribe topical hydrogen peroxide 1% cream and advise them that the child should be excluded from school until the lesions are crusted and healed
Explanation:Referral or admission is not necessary for this straightforward primary care case, which can be treated with topical antibiotics (with the addition of oral antibiotics containing fusidic acid if resistance is suspected or confirmed). However, it is important to advise the patient that they should not return to school or attend their school trip until 48 hours after starting antibiotic treatment or until the lesions have crusted and healed.
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. influenzae 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.

A healthy toddler is playing outside but suddenly stops breathing. The toddler's heart rate is over 100 bpm, but the skin colour is blue and the toddler is not moving. After calling for help and checking for a pulse, what is the most appropriate action to take?
Your Answer: Give five breaths of air via a face mask
Explanation:Steps for Neonatal Resuscitation
Neonatal resuscitation is a crucial process that can save a newborn’s life. Here are the steps to follow:
1. Dry the baby and assess its tone, breathing, and heart rate. If the baby is not breathing or gasping, open the airway by placing the baby on its back with the head in a neutral position. Give five inflation breaths of air via a face mask.
2. If the heart rate increases but the baby still cannot breathe, give breaths at a rate of 30-40 per minute until the baby can breathe independently.
3. Cardiac massage should only be done if the chest is not moving or the heart rate drops below 60 bpm. In this case, commence cardiac massage at a rate of three compressions to one breath.
4. Suction of the airways should only be done if there is an obvious airway obstruction that cannot be corrected by airway repositioning manoeuvres.
5. While it is important to keep the baby warm, avoid wrapping it tightly in a towel as it can obstruct the resuscitation process.
6. Intubation is not the first step in the resuscitation process. It is an option when resuscitation is failing and is the decision of a senior paediatrician.
By following these steps, you can increase the chances of a successful neonatal resuscitation.

A child is born at 28 weeks gestation and is transferred to the neonatal unit. After a few hours, the child shows signs of nasal flaring, chest wall indrawing, and appears to have jaundice. The observations show a heart rate of 75/min, a respiratory rate of 68/min, and a temperature of 38.2ºC. What is the most common organism responsible for the probable diagnosis?
Your Answer: Staphylococcus aureus
Correct Answer: Group B streptococcus
Explanation:The leading cause of early-onset neonatal sepsis in the UK is infection by group B streptococcus.
Neonatal Sepsis: Causes, Risk Factors, and Management
Neonatal sepsis is a serious bacterial or viral infection in the blood that affects babies within the first 28 days of life. It is categorized into early-onset (EOS) and late-onset (LOS) sepsis, with each category having distinct causes and common presentations. The most common causes of neonatal sepsis are group B streptococcus (GBS) and Escherichia coli, accounting for approximately two-thirds of cases. Premature and low birth weight babies are at higher risk, as well as those born to mothers with GBS colonization or infection during pregnancy. Symptoms can vary from subtle signs of illness to clear septic shock, and diagnosis is usually established through blood culture. Treatment involves early identification and use of intravenous antibiotics, with duration depending on ongoing investigations and clinical picture. Other important management factors include maintaining adequate oxygenation and fluid and electrolyte status.

Question 23
Incorrect

A 6-year-old girl walks with a limp due to right hip pain, which is relieved by rest and made worse by walking or standing. Her vital signs are normal. The Trendelenburg sign presents when she stands on her right leg.
X-rays reveal periarticular right hip swelling in soft tissue. A bone scan reveals reduced activity in the anterolateral right capital femoral epiphysis.
What is the most likely diagnosis?Your Answer: Epiphyseal dysplasia
Correct Answer: Legg-Calvé-Perthes disease
Explanation:Understanding Legg-Calvé-Perthes Disease and Differential Diagnoses
Legg–Calvé–Perthes disease is a condition that occurs due to vascular compromise of the capital epiphysis of the femur. The exact cause of this self-limiting disease is unclear, but it may be related to developmental changes in the hip’s blood supply. The compromised blood flow leads to ischaemic necrosis of the epiphysis. The retinacular arteries and their branches are the primary source of blood to the head of the femur, especially between the ages of 4 and 9 when the epiphyseal plate is forming. During this time, the incidence of Legg-Calvé-Perthes disease is highest.
Differential diagnoses for this condition include a slipped capital femoral epiphysis, septic arthritis, and epiphyseal dysplasia. A slipped capital femoral epiphysis would be visible on hip radiography, which is not the case in this scenario. Septic arthritis would cause systemic inflammatory responses, which are not present in this case. Epiphyseal dysplasia is a congenital defect that would typically present when the child starts to walk.
In addition to Legg-Calvé-Perthes disease, there is radiological evidence of synovitis and hip joint effusion in this scenario. However, synovitis is a non-specific sign and not a specific diagnosis. Understanding these differential diagnoses can help healthcare professionals provide accurate diagnoses and appropriate treatment plans for patients with hip joint issues.

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

Question 25

A 25-year-old pregnant woman is worried about her fetus after a routine ultrasound showed a large patent ductus arteriosus. She has read about indomethacin as a treatment option and wants to know more about the drug. What information will you provide her regarding the administration of indomethacin?
Your Answer: It is not used for closing the patent ductus arteriosus as it keeps the ductus arteriosus open
Correct Answer: It is given to the newborn if the echocardiogram shows patent ductus arteriosus one week after delivery
Explanation:Indomethacin is the preferred treatment for patent ductus arteriosus (PDA) in newborns, administered postnatally rather than antenatally to the mother. PDA is a congenital heart condition characterized by a left-right shunt where blood flows from the aorta to the pulmonary vessel through the patent ductus arteriosus. Although newborns with PDA may appear normal, a continuous machine-like murmur can be detected upon auscultation. Premature babies are more likely to have PDA, which may spontaneously close in asymptomatic patients. Symptomatic babies undergo an echocardiogram a few days after birth to determine whether medical or surgical management is necessary. Medical management involves administering indomethacin or ibuprofen to the newborn, while prophylactic treatment immediately after delivery or administering medication to the mother has no role in PDA closure. Prostaglandin analogues can maintain ductus arteriosus patency after birth and are useful in managing certain congenital heart diseases.
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.

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

A 15-year-old girl presents to your clinic with worries about delayed menarche. Upon taking her medical history, you find no developmental issues. She is currently at the 65th percentile for weight and 5th percentile for height. During the physical examination, you observe a short webbed neck and broad chest. After conducting a karyotype analysis, you discover an abnormality. What is the most prevalent heart condition linked to this clinical presentation?
Your Answer: Tricuspid regurgitation
Correct Answer: Bicuspid aortic valve
Explanation:The most frequently observed cardiac defect in individuals with Turner’s syndrome (45 XO) is a bicuspid aortic valve, which is more prevalent than coarctation of the aorta. Additionally, aortic root dilation and coarctation of the aorta are also associated with this condition.
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.

A 12-year-old female presents to her GP complaining of fatigue, weight loss, frequent urination, and excessive thirst. Her random plasma glucose level is 15 mmol/litre. The patient has a pre-existing condition since childhood that may be responsible for these symptoms. What is the most probable underlying condition?
Your Answer: Cystic fibrosis
Explanation:The onset of diabetes in a young person, as described in this presentation, is a classic symptom and has been confirmed by a random blood glucose level of >11 mmol/L. Among the given options, only cystic fibrosis has the potential to cause the development of diabetes. Cystic fibrosis typically manifests in childhood with respiratory symptoms, but as the disease progresses, other symptoms may appear. If the pancreas is affected, it can lead to the development of diabetes mellitus. However, it may take some time for the pancreas to be affected enough to cause diabetes, which is why children with cystic fibrosis may develop diabetes later in life. While the other conditions listed may cause fatigue or weight loss, they do not typically result in polyuria or polydipsia.
Cystic Fibrosis: Symptoms and Characteristics
Cystic fibrosis is a genetic disorder that affects various organs in the body, particularly the lungs and digestive system. The symptoms of cystic fibrosis can vary from person to person, but there are some common features that are often present. In the neonatal period, around 20% of infants with cystic fibrosis may experience meconium ileus, which is a blockage in the intestine caused by thick, sticky mucous. Prolonged jaundice may also occur, but less commonly. Recurrent chest infections are a common symptom, affecting around 40% of patients. Malabsorption is another common feature, with around 30% of patients experiencing steatorrhoea (excessive fat in the stool) and failure to thrive. Liver disease may also occur in around 10% of patients.
It is important to note that while many patients are diagnosed with cystic fibrosis during newborn screening or early childhood, around 5% of patients are not diagnosed until after the age of 18. Other features of cystic fibrosis may include short stature, diabetes mellitus, delayed puberty, rectal prolapse (due to bulky stools), nasal polyps, male infertility, and female subfertility. Overall, the symptoms and characteristics of cystic fibrosis can vary widely, but early diagnosis and treatment can help manage the condition and improve quality of life.

A 16-year-old girl visits her GP complaining of bilateral knee pain that has been bothering her for the past 2 months, particularly in the mornings. She has also been feeling generally fatigued, but denies experiencing any fevers, weight loss, or rashes. Her mother has a history of systemic lupus erythematosus (SLE), but otherwise, her family history is unremarkable. Upon examination, the patient's vital signs are within normal limits. There is mild oedema in both knees and ankles, and passive movement of the knee joints elicits tenderness. What is the most likely diagnosis?
Your Answer: Osgood-Schlatter disease
Correct Answer: Oligoarticular juvenile idiopathic arthritis
Explanation:The most common presentation of juvenile idiopathic arthritis (JIA) is oligoarticular (or pauciarticular) JIA, which typically affects up to four joints and is mild. The affected joints are usually larger ones like the knee, ankle, or elbow, and common symptoms include pain, stiffness, and fatigue. Other symptoms may include rash, fever, or dry/gritty eyes. Having a family history of autoimmune disease, such as systemic lupus erythematosus, increases the risk of developing JIA.
Ewing sarcoma is a primary bone cancer that usually affects long bones and causes localized pain and swelling. It is unlikely to present symmetrically and typically affects only one side of the body.
Osgood-Schlatter disease is an inflammation of the growth plate at the tibial tubercle, which is caused by traction from the quadriceps. It usually occurs in adolescents who are involved in sports/athletics and can affect both tibias, although it typically presents on only one side. The pain is worse during exercise and is not associated with knee effusions.
Systemic lupus erythematosus (SLE) is a chronic disorder that affects multiple systems and often includes arthritis or arthralgia. However, in this case, the absence of other systemic symptoms or rash suggests that the primary issue is arthritis, despite the family history.
Understanding Pauciarticular Juvenile Idiopathic Arthritis
Pauciarticular Juvenile Idiopathic Arthritis (JIA) is a type of arthritis that affects children under the age of 16 and lasts for more than six weeks. It is characterized by joint pain and swelling, typically in medium-sized joints such as the knees, ankles, and elbows. This type of JIA is called pauciarticular because it affects four or fewer joints. It is the most common type of JIA, accounting for approximately 60% of cases.
In addition to joint pain and swelling, children with pauciarticular JIA may experience a limp. It is also possible for the antinuclear antibody (ANA) test to be positive in cases of JIA, which is associated with anterior uveitis. It is important for parents and caregivers to be aware of the symptoms of pauciarticular JIA and seek medical attention if they suspect their child may be affected. Early diagnosis and treatment can help manage symptoms and prevent long-term joint damage.
