At what age would a typical toddler develop the skill to walk without any support?
Your Answer: 13-15 months
Explanation: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. The table below summarizes the major gross motor developmental milestones from 3 months to 4 years of age.
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.

A 12-year-old boy is presented by his father with a widespread skin rash. The boy has been experiencing itching for the past 3 days and has developed a fever along with the rash. During the examination, it is observed that the rash consists of macules, papules, crusted lesions, and vesicles that have spread across most of his body. The father has been administering ibuprofen to the boy for relief from fever and discomfort.
What is the probable diagnosis, and why is ibuprofen not recommended in this case?Your Answer: The increased risk of necrotising fasciitis
Explanation:The symptoms exhibited by this patient are consistent with chickenpox, including lesions at various stages of healing, fever, and itching. However, it is important to note that the use of NSAIDs can increase the risk of necrotising fasciitis in chickenpox patients. While ibuprofen is a suitable NSAID for patients of all ages, it is important to avoid aspirin due to the risk of Reye’s syndrome in children with chickenpox. Short-term use of ibuprofen during acute febrile illnesses is unlikely to cause significant gastrointestinal side effects.
Chickenpox: Causes, Symptoms, and Management
Chickenpox is a viral infection caused by the varicella zoster virus. It is highly contagious and can be spread through respiratory droplets. The virus can also reactivate later in life, causing shingles. Chickenpox is most infectious four days before the rash appears and until five days after the rash first appears. The incubation period is typically 10-21 days. Symptoms include fever, an itchy rash that starts on the head and trunk before spreading, and mild systemic upset.
Management of chickenpox is supportive and includes keeping cool, trimming nails, and using calamine lotion. School exclusion is recommended during the infectious period. Immunocompromised patients and newborns with peripartum exposure should receive varicella zoster immunoglobulin (VZIG). If chickenpox develops, IV acyclovir may be considered. Secondary bacterial infection of the lesions is a common complication, which may be increased by the use of NSAIDs. In rare cases, invasive group A streptococcal soft tissue infections may occur, resulting in necrotizing fasciitis. Other rare complications include pneumonia, encephalitis, disseminated haemorrhagic chickenpox, arthritis, nephritis, and pancreatitis.
Radiographic Findings in Varicella Pneumonia
Varicella pneumonia is a rare complication of chickenpox that can occur in immunocompromised patients or adults. Radiographic findings of healed varicella pneumonia may include miliary opacities throughout both lungs, which are of uniform size and dense, suggesting calcification. There is typically no focal lung parenchymal mass or cavitating lesion seen. These findings are characteristic of healed varicella pneumonia.

A 35-year-old woman presents at 16+4 weeks gestation for amniocentesis due to a high-risk combined screening test, which revealed trisomy 21. What is a potential late complication associated with this condition?
Your Answer: Alzheimer's disease
Explanation:Alzheimer’s disease is a late complication of Down syndrome. This is due to the extra copy of chromosome 21 that people with Down syndrome are born with, which produces an excess of amyloid precursor protein (APP). The buildup of beta-amyloid plaques in the brain, caused by too much APP protein, is a major risk factor for developing Alzheimer’s disease. By the age of 40, most people with Down syndrome have these plaques, as well as tau tangles, which further increase the risk of developing Alzheimer’s disease.
Chronic myeloid leukemia is not a late complication of Down syndrome, but acute lymphoblastic leukemia is. Symptoms of ALL may include frequent infections, bleeding, night sweats, bone and joint pain, and easy bruising.
Hirschsprung disease is a birth defect that can occur in babies with Down syndrome, but it is considered an early complication. It results from missing nerve cells in parts of the large intestine, causing severe constipation and sometimes intestinal obstruction.
Hypothyroidism is another late complication of Down syndrome, often caused by an autoimmune reaction. Hyperthyroidism is rare in people with Down syndrome.
Down’s syndrome is a genetic disorder that is characterized by various clinical features. These features include an upslanting of the palpebral fissures, epicanthic folds, Brushfield spots in the iris, a protruding tongue, small low-set ears, and a round or flat face. Additionally, individuals with Down’s syndrome may have a flat occiput, a single palmar crease, and a pronounced sandal gap between their big and first toe. Hypotonia, congenital heart defects, duodenal atresia, and Hirschsprung’s disease are also common in individuals with Down’s syndrome.
Cardiac complications are also prevalent in individuals with Down’s syndrome, with multiple cardiac problems potentially present. The most common cardiac defect is the endocardial cushion defect, also known as atrioventricular septal canal defects, which affects 40% of individuals with Down’s syndrome. Other cardiac defects include ventricular septal defect, secundum atrial septal defect, tetralogy of Fallot, and isolated patent ductus arteriosus.
Later complications of Down’s syndrome include subfertility, learning difficulties, short stature, repeated respiratory infections, hearing impairment from glue ear, acute lymphoblastic leukaemia, hypothyroidism, Alzheimer’s disease, and atlantoaxial instability. Males with Down’s syndrome are almost always infertile due to impaired spermatogenesis, while females are usually subfertile and have an increased incidence of problems with pregnancy and labour.

A 9-month-old girl is brought to their GP due to family concerns over the child's development. They were born at term via vaginal delivery, without complications. The child is otherwise well, without past medical history.
What developmental milestone would be most anticipated in this child?Your Answer: Good pincer grip
Correct Answer: Pass objects from one hand to another
Explanation:A 6-month-old boy was brought to the GP by his family who were concerned about his development. The GP tested his developmental milestones and found that he was able to hold objects with palmar grasp and pass objects from one hand to another. However, the child was not yet able to build a tower of 2 bricks, have a good pincer grip, or show a hand preference, which are expected milestones for older children. The GP reassured the family that the child’s development was within the normal range for his age.
Developmental Milestones for Fine Motor and Vision Skills
Fine motor and vision skills are important developmental milestones for infants and young children. These skills are crucial for their physical and cognitive development. The following tables provide a summary of the major milestones for fine motor and vision skills.
At three months, infants can reach for objects and hold a rattle briefly if given to their hand. They are visually alert, particularly to human faces, and can fix and follow objects up to 180 degrees. By six months, they can hold objects in a palmar grasp and pass them from one hand to another. They are visually insatiable, looking around in every direction.
At nine months, infants can point with their finger and demonstrate an early pincer grip. By 12 months, they have developed a good pincer grip and can bang toys together and stack bricks.
As children grow older, their fine motor skills continue to develop. By 15 months, they can build a tower of two blocks, and by 18 months, they can build a tower of three blocks. By two years old, they can build a tower of six blocks, and by three years old, they can build a tower of nine blocks. They also begin to draw, starting with circular scribbles at 18 months and progressing to copying vertical lines at two years old, circles at three years old, crosses at four years old, and squares and triangles at five years old.
In addition to fine motor skills, children’s vision skills also develop over time. At 15 months, they can look at a book and pat the pages. By 18 months, they can turn several pages at a time, and by two years old, they can turn one page at a time.
It is important to note that hand preference before 12 months is abnormal and may indicate cerebral palsy. Overall, these developmental milestones for fine motor and vision skills are important indicators of a child’s growth and development.

Question 5
Correct

As a doctor working on the paediatric ward, you encounter a 5-year-old patient who has become unresponsive. You call for assistance from another doctor and proceed to open the patient's airway, but the child is not breathing. After giving five rescue breaths, the other doctor checks for a femoral pulse, which is not present. You decide to initiate CPR while waiting for further help to arrive.
What is the appropriate ratio of chest compressions to rescue breaths and the recommended rate of chest compressions for this child?Your Answer: Chest compressions rate of 100-120/min, ratio of 15:2
Explanation:For both infants and children, the correct rate for chest compressions during paediatric BLS is 100-120/min. A ratio of 15:2 should be used when there are two or more rescuers, while a ratio of 30:2 is used for lay rescuers. It is important to avoid compressions that are too fast, as rates of 120-150/min do not allow enough time for blood to return to the ventricles. Using only one hand, the pressure should be reduced, but the compression rate should remain the same. Rates of 80-100/min are incorrect as they do not provide sufficient blood flow to vital organs.
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.

You are asked to evaluate a 3 day-old neonate who was born 2 weeks premature after a premature rupture of membranes. The infant has not passed meconium in the first 24 hours and has started vomiting. During the examination, you observe one episode of vomiting that is green in color, indicating bile. The baby appears irritable with a visibly distended abdomen, but has normal oxygen saturation and no fever. Palpation of the abdomen causes further discomfort, but no discrete mass is detected. What is the most probable underlying condition?
Your Answer: Necrotising enterocolitis
Correct Answer: Cystic fibrosis
Explanation:The presented history indicates a possible case of meconium ileus, where the thickened meconium caused a blockage in the small intestine due to cystic fibrosis. The neonate is likely to have a swollen abdomen and may not pass meconium. Vomiting may contain bile, which is different from pyloric stenosis that does not have bile. Additionally, there is no indication of intussusception or pyloric stenosis mass.
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 24-hour-old neonate requires a detailed examination on the Postnatal Ward. It was a forceps delivery at 41+3 weeks’ gestation. The detailed examination is normal, except you notice slight reduced tone in the right leg and reduced Moro reflex on the right. The leg is resting in a slightly extended position. The examination is otherwise normal.
What is the most appropriate management?Your Answer: Refer to Paediatric Neurology
Correct Answer: Refer to physiotherapy
Explanation:Assessing Erb’s Palsy in a Neonate: Appropriate Management and Investigations
Erb’s palsy is a neurological condition that commonly presents as reduced tone and movement in one arm, often due to shoulder dystocia during birth. In neonates, this can be identified by reduced Moro reflex and the arm resting in a waiter’s tip position. While Erb’s palsy is self-resolving, physiotherapy is recommended to strengthen the affected arm.
If there are no other neurological deficits, referral to a Paediatric Neurologist is not necessary. Cranial ultrasound and head MRI are also not appropriate investigations as they do not provide relevant information for this condition. Similarly, a shoulder X-ray is not necessary as the issue is neurological in nature. Overall, appropriate management and investigations for Erb’s palsy in a neonate involve physiotherapy and observation for resolution.

A 4-week-old baby girl is brought to the GP with feeding difficulties, increased respiratory effort, and poor weight gain over the past two weeks. During the examination, the GP notes a parasternal heave and a loud systolic murmur at the lower left sternal border.
What is the true statement about this condition?Your Answer: Prophylactic antibiotics before dental procedures are indicated in patients with this condition who do not have surgical repair of the defect
Correct Answer: Following closure of this defect, the patient is no longer considered at high risk of developing infective endocarditis
Explanation:Understanding Ventricular Septal Defect (VSD)
Ventricular septal defect (VSD) is a heart condition where there is a hole in the wall separating the two lower chambers of the heart. Here are some important points to know about VSD:
Closure of the defect reduces the risk of infective endocarditis: Once the VSD is surgically repaired, the patient is no longer considered at high risk of developing infective endocarditis. Therefore, prophylactic antibiotics are not required before high-risk procedures.
Cardiac catheterisation is not always necessary for diagnosis: While cardiac catheterisation was previously used to diagnose VSD, echocardiography methods have advanced, making it less invasive and more accurate.
Prophylactic antibiotics are not always necessary for dental procedures: Patients with surgically repaired VSD are not considered at high risk of developing infective endocarditis following dental work, so prophylactic antibiotics are not indicated. However, immunocompromised patients may require antibiotics.
Spontaneous closure is more common in infants: VSDs in infants under one year of age are more likely to close spontaneously. After the age of two, spontaneous closure is less likely.
Surgical repair is indicated for uncontrolled heart failure: If a patient with VSD shows signs of uncontrolled heart failure, including poor growth, surgical repair may be necessary.

Question 9

You are working in the pediatric unit and examine a 6-month-old infant. On examination, you observe a small left-sided hematoma over the parietal bone. The hematoma is soft to touch and does not extend beyond the margins of the parietal bone. The infant is otherwise healthy. The infant was born at term via spontaneous vaginal delivery, and there were no prenatal or labor complications. What is the probable diagnosis?
Your Answer: Cephalhaematoma
Explanation:Medical students may mistake a cephalhaematoma for a caput succedaneum, but there are distinguishing features. Cephalhaematomas typically develop after birth and do not cross the skull’s suture lines, as the blood is contained between the skull and periosteum. Caput succedaneum, on the other hand, is an extraperiosteal collection of blood that can cross over the suture lines and may be present at birth. Subaponeurotic haemorrhages are a serious condition caused by bleeding in the potential space between the periosteum and subgaleal aponeurosis. They typically present as a boggy swelling that grows insidiously and is not confined to the skull sutures. In severe cases, the neonate may experience haemorrhagic shock. Chignons are birth traumas that occur after the use of a ventouse device during delivery, while a cranial abrasion usually occurs after a caesarean section or instrumental delivery.
A cephalohaematoma is a swelling that appears on a newborn’s head, usually a few hours after delivery. It is caused by bleeding between the skull and periosteum, with the parietal region being the most commonly affected site. This condition may lead to jaundice as a complication and can take up to three months to resolve.
In comparison to caput succedaneum, which is another type of swelling that can occur on a newborn’s head, cephalohaematoma is more localized and does not cross suture lines. Caput succedaneum, on the other hand, is a diffuse swelling that can cross suture lines and is caused by fluid accumulation in the scalp tissue. Both conditions are usually harmless and resolve on their own, but medical attention may be necessary in severe cases.

A premature neonate is delivered via category II emergency caesarean section at 34+3 weeks for fetal distress. The obstetrician notes the baby is delivered with the cord wrapped around its neck and appears floppy and 'blue'. The neonatal team immediately begins resuscitation as the initial APGAR score is 3. At 10 minutes, the score is 5 due to cyanosis, heart rate of 120 bpm, minimal response to stimulation, poor tone, slow and irregular respiratory effort with a respiratory rate of 12/min. What is the most appropriate management of this premature neonate to reduce hypoxic ischemic encephalopathy (HIE)?
Your Answer: Therapeutic cooling
Explanation:Therapeutic Cooling for Neonates with Hypoxic Brain Injury
Therapeutic cooling, also known as therapeutic hypothermia, is a medical procedure that involves deliberately lowering a patient’s body temperature to cool the brain and prevent brain damage. This procedure has been proposed for several therapeutic uses, including neuroprotection during open-heart and neurosurgical procedures, in patients following a return of spontaneous circulation post-ventricular fibrillation arrest, in patients with trauma head injuries, in patients who have suffered acute ischemic stroke, and in neonates with moderate to severe hypoxic ischemic encephalopathy (HIE). However, the only use whose efficacy has been consistently proven in existing literature is the use of therapeutic cooling in neonates.
The use of therapeutic cooling in carefully selected term neonates with moderate to severe HIE has been recommended as standard care by the National Institute for Health and Care Excellence (NICE). It has been shown in studies to decrease mortality and improve the neurological and neurodevelopmental outcomes of treated neonates. Hypoxic perinatal brain injury is caused by a decrease in the amount of oxygen supplied to an infant’s brain just prior to, or during the process of, labor. Neonates who survive a hypoxic brain injury can develop HIE, which occurs in an estimated 2.5/1000 term births in developed countries and 26/1000 term births in the developing world.
Therapeutic cooling remains the only intervention shown to reduce neuronal damage caused by perinatal hypoxia. The procedure is thought to influence the extent of secondary neuronal death in a multifactorial manner, although the exact way in which it achieves this is not fully understood. The procedure involves placing the infant on a cooling blanket or mattress circulated with coolant fluid or circulating cold water in a cap fitted around the head. Temperature is continuously monitored throughout the treatment using either a rectal or nasopharyngeal thermometer. Close surveillance of infants during the cooling process is required given the risk for complications of both HIE and the process of cooling itself.

A 4-year-old boy is admitted to hospital. He was diagnosed with Down syndrome soon after birth. He has not opened his bowels for the past few days and complains of abdominal pain. His abdomen is distended, and he has had several episodes of vomiting. The mother denies any complication during pregnancy. An abdominal X-ray does not show any double bubble sign but rather shows a picture of bowel obstruction.
Which of the following investigations would provide a definitive diagnosis?Your Answer: Abdominal ultrasound
Correct Answer: Rectal biopsy
Explanation:Diagnostic Procedures for Hirschsprung’s Disease
Hirschsprung’s disease is a congenital condition that causes functional obstruction of the colon due to the absence of parasympathetic ganglion cells in the rectum. Diagnosis is made through a rectal biopsy, which confirms the absence of ganglion cells. Other diagnostic procedures, such as abdominal ultrasound, upper GI endoscopy, erect chest X-ray, and colonoscopy, are not useful in diagnosing Hirschsprung’s disease. An abdominal X-ray may be performed to rule out other causes of abdominal distension. However, in most cases, rectal biopsy is the definitive diagnostic procedure for Hirschsprung’s disease.

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

A 38-week-old neonate has been born with an abdominal defect described as 7 cm of herniated bowel through the abdominal wall. The bowel is exposed without a covering. The patient is hypotensive (50/30), tachycardic (220 bpm) and hypothermic (35.2 °C). Bloods were taken, which showed the following:
Investigation Result Normal value
Haemoglobin 190 g/l Female: 115–155 g/l
Male: 135–175 g/l
White cell count 30 × 109/l 4–11 × 109/l
C-reactive protein (CRP) 25 mg/l 0–10 mg/l
What is the most appropriate management?Your Answer: Incubate, fluid-resuscitate, pass nasogastric (NG) tube, surgery within a few hours
Explanation:Management of Gastroschisis in Neonates
Gastroschisis is a condition in which the abdominal contents herniate through the abdominal wall, without the covering of a sac of amniotic membrane and peritoneum. This poses a higher risk to the neonate than exomphalos, which has a covering. The management of gastroschisis involves incubation to maintain body temperature, fluid-resuscitation to prevent dehydration and hypovolaemia, and surgical intervention within a few hours, unless there is evidence of impaired bowel perfusion. Elective surgery is not appropriate for gastroschisis. Restricting fluids would result in organ hypoperfusion and death. Abdominal X-rays are not necessary, and surgical review is obviously appropriate, but surgical intervention is the priority.

A 14-year-old girl presents with increased urinary frequency and thirst. Her initial observations and clinical examination revealed no abnormalities. On initial blood tests, the only abnormalities found are a urea of 10.5 mmol/l (normal range 2.5–6.5 mmol/l) and a borderline serum osmolality of 270 mOsmol/kg (normal range 270–295 mOsmol/kg). She subsequently had water deprivation testing. Time Investigation Result Normal range 0 hours Serum osmolality 270 mOsmol/kg 270–295 mOsmol/kg 4 hours – testing stopped Serum osmolality Urine osmolality 300 mOsmol/kg 285 mOsmol/kg 270–295 mOsmol/kg 350–1000 mOsmol/kg After administration of desmopressin Urine osmolality 287 mOsmol/kg 350–1000 mOsmol/kg. What is the most likely diagnosis based on the investigative results?
Your Answer: Nephrogenic diabetes insipidus
Explanation:Understanding Nephrogenic Diabetes Insipidus: Differentiating it from Primary Polydipsia and Cranial Diabetes Insipidus
Nephrogenic diabetes insipidus (DI) is a condition where the nephron fails to concentrate urine despite adequate levels of antidiuretic hormone (ADH) due to insensitivity of the ADH receptors. In contrast, primary polydipsia is characterized by normal ADH secretion and renal sensitivity to ADH, but compulsive water consumption leading to polyuria. Cranial diabetes insipidus, on the other hand, is caused by impaired ADH secretion.
To differentiate between these conditions, a water deprivation test is conducted. In nephrogenic DI, after eight hours of water deprivation, serum osmolality increases while urine osmolality remains low. Administering 2 μg desmopressin has no effect as the ADH receptors remain insensitive. In primary polydipsia, ADH secretion increases during water deprivation, resulting in retention of water by the kidneys, leading to normal serum osmolality and increased urine osmolality. In cranial diabetes insipidus, serum osmolality increases after water deprivation, but administration of desmopressin should result in a return to normal serum osmolality and a concurrent rise in urine osmolality.
In cases where the water deprivation test shows abnormal results, further testing may be required. However, in the case of nephrogenic DI, the abnormal results indicate impairment in osmolality regulation due to insensitivity of the renal ADH receptors.

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: 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.

Your Answer: Diphtheria
Correct Answer: Measles
Explanation:Measles: A Highly Infectious Viral Disease
Measles is a viral disease caused by an RNA paramyxovirus. It is one of the most infectious known viruses and is spread through aerosol transmission. The disease has an incubation period of 10-14 days and is infective from the prodromal phase until four days after the rash starts. Measles is now rare in developed countries due to immunization programs, but outbreaks can occur when vaccination rates drop, such as during the MMR controversy of the early 2000s.
The disease is characterized by a prodromal phase, which includes irritability, conjunctivitis, fever, and Koplik spots. The latter typically develop before the rash and are white spots on the buccal mucosa. The rash starts behind the ears and then spreads to the whole body, becoming a discrete maculopapular rash that may become blotchy and confluent. Desquamation may occur after a week, typically sparing the palms and soles. Diarrhea occurs in around 10% of patients.
Measles is mainly managed through supportive care, and admission may be considered in immunosuppressed or pregnant patients. The disease is notifiable, and public health should be informed. Complications of measles include otitis media, pneumonia (the most common cause of death), encephalitis (typically occurring 1-2 weeks following the onset of the illness), subacute sclerosing panencephalitis (very rare, may present 5-10 years following the illness), febrile convulsions, keratoconjunctivitis, corneal ulceration, diarrhea, increased incidence of appendicitis, and myocarditis.
If an unimmunized child comes into contact with measles, MMR should be offered within 72 hours. Vaccine-induced measles antibody develops more rapidly than that following natural infection.

A mother brings her 6-year-old daughter to see you at the General Practice surgery where you are working as a Foundation Year 2 doctor. The daughter had a runny nose and sore throat for the past few days but then developed bright red rashes on both her cheeks. She now has a raised itchy rash on her chest, that has a lace-like appearance, but feels well. She has no known long-term conditions and has been developing normally.
What is the most likely diagnosis?Your Answer: Parvovirus infection
Explanation:Common Skin Rashes and Infections: Symptoms and Characteristics
Parvovirus Infection: Also known as ‘slapped cheek syndrome’, this mild infection is characterized by a striking appearance. However, it can lead to serious complications in immunocompromised patients or those with sickle-cell anaemia or thalassaemia.
Pityriasis Rosea: This rash starts with an oval patch of scaly skin and is followed by small, scaly patches that spread across the body.
Impetigo: A superficial infection caused by Staphylococcus or Streptococcus bacteria, impetigo results in fluid-filled blisters or sores that burst and leave a yellow crust.
Scarlet Fever: This rash is blotchy and rough to the touch, typically starting on the chest or abdomen. Patients may also experience headache, sore throat, and high temperature.
Urticaria: This itchy, raised rash is caused by histamine release due to an allergic reaction, infection, medications, or temperature changes. It usually settles within a few days.

Which one of the following is not included in the Apgar score for evaluating a neonate?
Your Answer: Capillary refill time
Explanation:The Apgar score is a tool used to evaluate the health of a newborn baby. It is recommended by NICE to be assessed at 1 and 5 minutes after birth, and again at 10 minutes if the initial score is low. The score is based on five factors: pulse, respiratory effort, color, muscle tone, and reflex irritability. A score of 0-3 is considered very low, 4-6 is moderate low, and 7-10 indicates that the baby is in good health. The score helps healthcare professionals quickly identify any potential issues and provide appropriate care.

A mother brings her 12-year-old boy into the Emergency Department. She is concerned as he has started to limp over the last few days and is in pain. There is no history of trauma; he has no temperature and is otherwise well. You notice he is overweight for his age.
Which is the most likely diagnosis?Your Answer: Slipped femoral epiphysis
Explanation:Pediatric Hip Conditions: Slipped Femoral Epiphysis, Perthes’ Disease, Septic Arthritis, and Juvenile Idiopathic Arthritis
Hip conditions in children can present with a variety of symptoms and causes. One common condition is slipped femoral epiphysis, which typically affects boys aged 10-16 who are overweight. Symptoms include a painful limp, limited internal rotation, and displacement of the femoral head on X-ray. Treatment involves surgical fixation.
Another condition is Perthes’ disease, which is avascular necrosis of the femoral head and typically affects younger children aged 4-10, more commonly in boys. Symptoms include an intermittent limp and limited joint movement. Treatment can be medical or surgical, but surgery may result in limb shortening and a permanent limp.
Septic arthritis presents with an acutely painful, inflamed, and swollen joint, often with fever. It is more common in patients with underlying joint disease or a history of trauma. Musculoskeletal back pain is unlikely in this scenario.
Juvenile idiopathic arthritis is an autoimmune inflammatory joint disease seen in children under 16. It presents with joint swelling, morning pain, limping, lethargy, reduced activity, and poor appetite, and is associated with anterior uveitis and spiking fevers. However, it is unlikely in this scenario due to the chronicity of symptoms and the child’s overall health.
In conclusion, pediatric hip conditions can have various causes and symptoms, and proper diagnosis and treatment are crucial for optimal outcomes.

A 6-year-old girl is presented to the GP clinic with a flare-up of asthma. Upon examination, she displays bilateral expiratory wheezing but no signs of respiratory distress. Her respiratory rate is 24 breaths per minute and PEF is approximately 60% of normal. What is the recommended course of action for steroid treatment?
Your Answer: Oral prednisolone for 3 days
Explanation:According to the 2016 guidelines of the British Thoracic Society, children should be given a specific dose of steroids based on their age. For children under 2 years, the dose should be 10 mg of prednisolone, for those aged 2-5 years, it should be 20 mg, and for those over 5 years, it should be 30-40 mg. Children who are already taking maintenance steroid tablets should receive a maximum dose of 60 mg or 2 mg/kg of prednisolone. If a child vomits after taking the medication, the dose should be repeated, and if they are unable to retain the medication orally, intravenous steroids should be considered. The duration of treatment should be tailored to the number of days required for recovery, and a course of steroids exceeding 14 days does not require tapering.
Managing Acute Asthma Attacks in Children
When it comes to managing acute asthma attacks in children, it is important to assess the severity of the attack and take appropriate action. For children between the ages of 2 and 5, those with severe or life-threatening asthma should be immediately transferred to the hospital. For moderate attacks, children should have a SpO2 level above 92% and no clinical features of severe asthma. However, for severe attacks, children may have a SpO2 level below 92%, be too breathless to talk or feed, have a heart rate above 140/min, and use accessory neck muscles. For life-threatening attacks, children may have a SpO2 level below 92%, a silent chest, poor respiratory effort, agitation, altered consciousness, and cyanosis.
For children over the age of 5, it is recommended to attempt to measure PEF in all cases. For moderate attacks, children should have a SpO2 level above 92%, a PEF level above 50% best or predicted, and no clinical features of severe asthma. For severe attacks, children may have a SpO2 level below 92%, a PEF level between 33-50% best or predicted, and be unable to complete sentences in one breath or too breathless to talk or feed. For life-threatening attacks, children may have a SpO2 level below 92%, a PEF level below 33% best or predicted, a silent chest, poor respiratory effort, altered consciousness, and cyanosis.
For children with mild to moderate acute asthma, bronchodilator therapy should be given via a beta-2 agonist and spacer (or close-fitting mask for children under 3 years old). One puff should be given every 30-60 seconds up to a maximum of 10 puffs. If symptoms are not controlled, the beta-2 agonist should be repeated and the child should be referred to the hospital. Steroid therapy should also be given to all children with an asthma exacerbation for 3-5 days, with the usual prednisolone dose varying based on age and weight.

Which of the following symptoms is not associated with acute or subacute lead poisoning in infants?
Your Answer: Pica
Correct Answer: Blue line on the gums
Explanation:Lead Poisoning in Infancy
Lead poisoning in infancy can cause various symptoms such as anaemia, pica, abdominal colic, and encephalopathy. However, the blue line on the gingival margin, which is a characteristic feature of very chronic lead poisoning, is unlikely to occur in infants. Lead poisoning can lead to anaemia due to erythroid hypoplasia and/or haemolysis. Pica and abdominal colic are common symptoms of lead poisoning in infants, while encephalopathy is only seen in severe cases. It is important to be aware of these symptoms and seek medical attention if lead poisoning is suspected in infants. Proper management and treatment can prevent further complications and ensure the child’s well-being.

A 16-month-old toddler comes to your primary care clinic after experiencing a seizure. The parents are extremely worried as one of their relatives has epilepsy and they fear that their child may have it too. Upon examination, the child seems alert and has a temperature of 38.4C, which the parents say has been present for four days. They have been giving calpol, which has helped to bring it down from a high of 40.7ºC. You also notice a pink, maculopapular rash on the chest with minimal spread to the limbs, which the mother says she noticed this morning. The child has been eating but has had some diarrhea, and you can feel some enlarged glands on the back of their head. There is no rash in the mouth. Based on your observations, what do you think is the most probable underlying cause of the child's symptoms?
Your Answer: Measles
Correct Answer: Herpes virus 6
Explanation:Herpes virus 6 is responsible for causing Roseola infantum, which is identified by a high fever lasting for 3-5 days followed by a rash that appears on the chest and spreads to the limbs over a period of 2 days. This rash typically emerges as the fever subsides. Kaposi’s sarcoma is linked to Herpes virus 8 and is commonly observed in individuals with AIDS. ‘Slapped cheek syndrome’ is caused by Parvovirus B19, which initiates a rash that starts on the cheeks and then spreads. Group A Streptococcus is known to cause infections of the throat (also known as strep throat) and skin, including cellulitis, erysipelas, and impetigo.
Understanding Roseola Infantum
Roseola infantum, also known as exanthem subitum or sixth disease, is a common illness that affects infants and is caused by the human herpes virus 6 (HHV6). This disease has an incubation period of 5-15 days and is typically seen in children aged 6 months to 2 years. The most common symptoms of roseola infantum include a high fever that lasts for a few days, followed by a maculopapular rash. Other symptoms may include Nagayama spots, which are papular enanthems on the uvula and soft palate, as well as cough and diarrhea.
In some cases, febrile convulsions may occur in around 10-15% of children with roseola infantum. While this can be concerning for parents, it is important to note that this is a common occurrence and typically resolves on its own. Additionally, HHV6 infection can lead to other possible consequences such as aseptic meningitis and hepatitis.
It is important to note that school exclusion is not necessary for children with roseola infantum. While this illness can be uncomfortable for infants, it is typically not serious and resolves on its own within a few days.

A 4-week-old infant boy born at 37 weeks gestation by caesarian section is presented to his pediatrician for a routine check-up. The pediatrician observes that the neonate's urethral meatus is situated on the ventral aspect of the penile shaft, instead of the distal glans penis. What other congenital anomaly is this neonate more likely to have?
Your Answer: Posterior urethral valve
Correct Answer: Cryptorchidism
Explanation:Hypospadias is often accompanied by cryptorchidism in neonates, indicating a potential issue with embryological urogenital migration that may be linked to endocrine disruptions during pregnancy, such as low serum androgens. Imperforate anus, obstructive uropathy with a patent urachus, and posterior urethral valve are not associated with hypospadias and would present with different symptoms or complications.
Understanding Hypospadias: A Congenital Abnormality of the Penis
Hypospadias is a condition that affects approximately 3 out of 1,000 male infants. It is a congenital abnormality of the penis that is usually identified during the newborn baby check. However, if missed, parents may notice an abnormal urine stream. This condition is characterized by a ventral urethral meatus, a hooded prepuce, and chordee in more severe forms. The urethral meatus may open more proximally in the more severe variants, but 75% of the openings are distally located. There appears to be a significant genetic element, with further male children having a risk of around 5-15%.
Hypospadias most commonly occurs as an isolated disorder, but it can also be associated with other conditions such as cryptorchidism (present in 10%) and inguinal hernia. Once hypospadias has been identified, infants should be referred to specialist services. Corrective surgery is typically performed when the child is around 12 months of age. It is essential that the child is not circumcised prior to the surgery as the foreskin may be used in the corrective procedure. In boys with very distal disease, no treatment may be needed. Understanding hypospadias is important for parents and healthcare providers to ensure proper management and treatment of this condition.

Question 24

A 6-month-old boy is brought to the paediatrics emergency department by his parents. His parents report that he has had a fever for 2 days with reduced activity and feeding. On examination, he is not smiling, his respiratory rate is 50 breaths/minute (normal range: 30-60 breaths/minute) and his heart rate is 155 beats/minute (100-160 beats/minute). He also has reduced skin turgor and looks pale. A nurse looks up the NICE traffic light system to identify his risk of serious illness.
What is the most concerning symptom in this patient?Your Answer: Reduced activity and feeding
Correct Answer: Reduced skin turgor
Explanation:According to the NICE traffic light system, reduced skin turgor is a red flag symptom in children. This system is used to identify the risk of serious illness in children. Decreased activity is considered an amber symptom, while age <6 months is not a red flag symptom. Age 3-6 months with a temperature of >=39ºC is an amber flag symptom, and age <3 months with a temperature of >=38°C is a red flag symptom. A respiratory rate of >60 breaths/minute is also a red flag symptom. Finally, a heart rate of >160 beats/minute in children under 12 months is an amber flag symptom.
The NICE Feverish illness in children guidelines were introduced in 2007 and updated in 2013. These guidelines use a ‘traffic light’ system to assess the risk of children under 5 years old presenting with a fever. It is important to note that these guidelines only apply until a clinical diagnosis of the underlying condition has been made. When assessing a febrile child, their temperature, heart rate, respiratory rate, and capillary refill time should be recorded. Signs of dehydration should also be looked for. Measuring temperature should be done with an electronic thermometer in the axilla if the child is under 4 weeks old or with an electronic/chemical dot thermometer in the axilla or an infrared tympanic thermometer.
The risk stratification table includes green for low risk, amber for intermediate risk, and red for high risk. The table includes categories such as color, activity, respiratory, circulation and hydration, and other symptoms. If a child is categorized as green, they can be managed at home with appropriate care advice. If they are categorized as amber, parents should be provided with a safety net or referred to a pediatric specialist for further assessment. If a child is categorized as red, they should be urgently referred to a pediatric specialist. It is important to note that oral antibiotics should not be prescribed to children with fever without an apparent source, and a chest x-ray does not need to be routinely performed if a pneumonia is suspected but the child is not going to be referred to the hospital.

A two-hour-old baby born at 38+5 weeks in the Special Care Baby Unit is exhibiting mild respiratory distress, with subcostal recessions and grunting. The baby's respiratory rate is 68/min without any apnoeas, their heart rate is 150 bpm, and their axillary temperature is 36.8ºC. The baby appears pink, with normal pre-post ductal saturations and no additional heart sounds. Fontanelles are normal, and their birth weight is within the normal range.
The chest X-ray shows hyperinflation and a thin fluid line in the right horizontal fissure. What is the most significant risk factor for the likely diagnosis?Your Answer: Caesarean section delivery
Explanation:Transient tachypnoea of the newborn (TTN) is most likely the diagnosis for a baby with mildly raised respiratory rate and increased work of breathing in the hours after labour, with all other observations being normal. Caesarean section delivery is the most important risk factor for TTN, with other risk factors including male gender, birth asphyxia, and gestational diabetes. Breech presentation is not a risk factor for TTN, while meconium in liquor would make meconium aspiration the most likely diagnosis. Fever during vaginal delivery would make other infective differentials more likely, but a sepsis screen would be needed to rule this out before a diagnosis of TTN could be made.
Understanding Transient Tachypnoea of the Newborn
Transient tachypnoea of the newborn (TTN) is a common respiratory condition that affects newborns. It is caused by the delayed resorption of fluid in the lungs, which can lead to breathing difficulties. TTN is more common in babies born via caesarean section, as the fluid in their lungs may not be squeezed out during the birth process. A chest x-ray may show hyperinflation of the lungs and fluid in the horizontal fissure.
The management of TTN involves observation and supportive care. In some cases, supplementary oxygen may be required to maintain oxygen saturation levels. However, TTN usually resolves within 1-2 days. It is important for healthcare professionals to monitor newborns with TTN closely and provide appropriate care to ensure a full recovery. By understanding TTN and its management, healthcare professionals can provide the best possible care for newborns with this condition.

A 4-year-old boy is brought to the paediatric assessment unit by his parents after they witnessed him having a seizure. He had been experiencing a fever and cold symptoms for the past three days. His father also noticed a rash on his chest and a swollen tongue yesterday. The boy has met all of his developmental milestones prior to this incident.
After being assessed, the medical team has determined that the boy is safe to go home. What advice should the parents be given?Your Answer: An ambulance must be called if another seizure occurs and persists for longer than five minutes
Explanation:Parents should be informed that if a febrile convulsion lasts longer than five minutes, they should call an ambulance. The presence of a sandpaper rash and strawberry tongue in the vignette suggests a diagnosis of scarlet fever, which is often associated with febrile seizures. However, it is important to note that simple febrile seizures lasting only a few minutes are generally not a cause for concern. It is not recommended to prescribe prophylactic antipyretics as they have not been shown to reduce seizure frequency according to NICE guidelines. Referral to a paediatric neurologist is only necessary if the child has neurodevelopmental delay or signs of a neurocutaneous syndrome or metabolic disorder.
Febrile convulsions are seizures caused by fever in children aged 6 months to 5 years. They typically last less than 5 minutes and are most commonly tonic-clonic. There are three types: simple, complex, and febrile status epilepticus. Children who have had a first seizure or any features of a complex seizure should be admitted to pediatrics. Regular antipyretics do not reduce the chance of a febrile seizure occurring. The overall risk of further febrile convulsion is 1 in 3, with risk factors including age of onset, fever duration, family history, and link to epilepsy. Children without risk factors have a 2.5% risk of developing epilepsy, while those with all three features have a much higher risk.

A father brings his 5-year-old child for a routine general practice (GP) appointment. During the consultation, the father mentions that the child recently started playing soccer and has been enjoying it. You observe that the child has a short stature, upslanting palpebral fissures, a flat occiput and a single palmar crease.
What should be the GP's primary concern for this 5-year-old child with short stature, upslanting palpebral fissures, a flat occiput, and a single palmar crease who recently started playing soccer?Your Answer: Atlantoaxial instability
Explanation:Individuals with Down syndrome who engage in sports that have a higher risk of neck dislocation, such as gymnastics, boxing, diving, horse riding, rugby, and trampolining, should be screened for Atlantoaxial instability. This complication of Down syndrome can increase the likelihood of sudden neck dislocation, and while the child in this scenario does not exhibit any immediate concerns related to hypothyroidism, dementia, leukaemia, or seizures, it is important to prioritize screening for Atlantoaxial instability.
Down’s syndrome is a genetic disorder that is characterized by various clinical features. These features include an upslanting of the palpebral fissures, epicanthic folds, Brushfield spots in the iris, a protruding tongue, small low-set ears, and a round or flat face. Additionally, individuals with Down’s syndrome may have a flat occiput, a single palmar crease, and a pronounced sandal gap between their big and first toe. Hypotonia, congenital heart defects, duodenal atresia, and Hirschsprung’s disease are also common in individuals with Down’s syndrome.
Cardiac complications are also prevalent in individuals with Down’s syndrome, with multiple cardiac problems potentially present. The most common cardiac defect is the endocardial cushion defect, also known as atrioventricular septal canal defects, which affects 40% of individuals with Down’s syndrome. Other cardiac defects include ventricular septal defect, secundum atrial septal defect, tetralogy of Fallot, and isolated patent ductus arteriosus.
Later complications of Down’s syndrome include subfertility, learning difficulties, short stature, repeated respiratory infections, hearing impairment from glue ear, acute lymphoblastic leukaemia, hypothyroidism, Alzheimer’s disease, and atlantoaxial instability. Males with Down’s syndrome are almost always infertile due to impaired spermatogenesis, while females are usually subfertile and have an increased incidence of problems with pregnancy and labour.

You are observing a doctor on the neonatal ward who is asked to assess a 3-hour-old baby delivered at 40+5 weeks by ventouse. The mother is concerned about the appearance of her baby's head. Upon examination, you notice a soft, puffy swelling at the back of the head with some light bruising from the ventouse cup. The swelling seems to extend across the suture lines. However, the baby appears to be in good health otherwise, and the neonatal hearing screen conducted earlier that morning was normal. What could be the probable cause of this presentation?
Your Answer: Caput succedaneum
Explanation:Caput succedaneum is a puffy swelling that occurs over the presenting part during prolonged ventouse delivery and resolves spontaneously. It differs from bulging fontanelle, which is caused by increased intracranial pressure, and cephalohaematoma, which is a swelling caused by fluid collecting between the periosteum and skull. Hydrocephalus is a condition where there is an accumulation of cerebrospinal fluid around the brain, and subaponeurotic haemorrhage is a rare condition caused by rupturing of emissary veins.
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.

A 4-week old baby is seen by the GP. The baby was born in breech position at 38+4 weeks gestation without any complications during delivery. However, two days after birth, the baby developed jaundice and was treated with phototherapy. The newborn physical examination was normal. The mother has a medical history of anaemia, asthma, and coeliac disease. The baby is currently thriving and is on the 45th centile. What investigations should the GP consider referring the baby for based on their medical history?
Your Answer: Serum bilirubin levels
Correct Answer: Ultrasounds of pelvis
Explanation: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.

A 7-year-old girl is brought to the pediatrician's office by her father. She has been experiencing nighttime itching around her bottom and has mentioned to her father that she has seen small white strands moving in her stool. She is not constipated and is generally healthy. No one else in the household has reported similar symptoms. The girl lives with her father and her two-year-old brother.
What should be the next course of action?Your Answer: Mebendazole and hygiene measures for his parents and three-month-old sister
Correct Answer: Mebendazole and hygiene measures for the patient and his parents, as his sister is too young
Explanation:It is recommended to treat asymptomatic household contacts of patients with threadworms, even if they show no symptoms. In the case of this boy with threadworms, the appropriate course of action would be to administer Mebendazole and advise on hygiene measures for both the patient and his parents. It is not necessary to send a sample to the laboratory for confirmation as empirical treatment is recommended. Advising on hygiene and fluid intake alone would not be sufficient to treat the infection. It is important to note that Mebendazole should not be given to children under six months old, so treating the patient’s three-month-old sister is not appropriate. Permethrin is not a suitable treatment for threadworms as it is used to treat scabies.
Threadworm Infestation in Children
Threadworm infestation, caused by Enterobius vermicularis or pinworms, is a common occurrence among children in the UK. The infestation happens when eggs present in the environment are ingested. In most cases, threadworm infestation is asymptomatic, but some possible symptoms include perianal itching, especially at night, and vulval symptoms in girls. Diagnosis can be made by applying Sellotape to the perianal area and sending it to the laboratory for microscopy to see the eggs. However, most patients are treated empirically, and this approach is supported in the CKS guidelines.
The CKS recommends a combination of anthelmintic with hygiene measures for all members of the household. Mebendazole is the first-line treatment for children over six months old, and a single dose is given unless the infestation persists. It is essential to treat all members of the household to prevent re-infection. Proper hygiene measures, such as washing hands regularly, keeping fingernails short, and washing clothes and bedding at high temperatures, can also help prevent the spread of threadworm infestation.
