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

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

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

Snoring in Children: Possible Causes

Snoring in children can be caused by various factors. One of the common causes is obesity, which can lead to the narrowing of the airways and difficulty in breathing during sleep. Another possible cause is nasal problems such as polyps, deviated septum, and hypertrophic nasal turbinates, which can also obstruct the airways and cause snoring. Recurrent tonsillitis can also contribute to snoring, as the inflamed tonsils can block the air passages.

In some cases, snoring in children may be associated with certain medical conditions such as Down’s syndrome and hypothyroidism. These conditions can affect the structure and function of the respiratory system, leading to snoring and other breathing difficulties.

It is important to identify the underlying cause of snoring in children and seek appropriate treatment to prevent potential health complications. Parents should consult a healthcare professional if their child snores regularly or experiences other symptoms such as daytime sleepiness, difficulty concentrating, or behavioral problems.

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

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

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

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

Understanding Vesicoureteric Reflux

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

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

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

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

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.

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

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

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

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

Differential diagnosis of vomiting and poor weight gain in infants

Vomiting and poor weight gain are common symptoms in infants, but they can be caused by different conditions that require specific management. One possible cause is pyloric stenosis, which results from an enlarged muscle at the outlet of the stomach, leading to projectile vomiting, dehydration, and failure to thrive. Another possible cause is gastro-oesophageal reflux disease (GORD), which may also involve vomiting, but not projectile, and may respond to conservative measures such as frequent feeds and upright positioning, or medication such as Gaviscon® or proton pump inhibitors. Cow’s milk protein allergy is another potential cause, which may present with a range of symptoms, including vomiting, but not projectile, and may require an exclusion diet for the mother if breastfeeding. Gastroenteritis is a common cause of vomiting and diarrhoea in infants, but it usually resolves within a few days and does not cause an abdominal mass. Finally, volvulus is a rare but serious condition that involves a twisted bowel, leading to acute obstruction and ischaemia, which requires urgent surgical intervention. Therefore, a careful history, examination, and investigations, such as ultrasound or blood tests, may help to differentiate these conditions and guide appropriate treatment.

Croup affects 6 months to 3 years old and is caused by parainfluenza virus, while bronchiolitis affects 1-9 month olds and is caused by respiratory syncytial virus. Neonatal respiratory distress can occur due to prematurity.

Understanding Croup: A Respiratory Infection in Infants and Toddlers

Croup is a type of upper respiratory tract infection that commonly affects infants and toddlers. It is characterized by a barking cough, fever, and coryzal symptoms, and is caused by a combination of laryngeal oedema and secretions. Parainfluenza viruses are the most common cause of croup. The condition typically peaks between 6 months and 3 years of age, and is more prevalent during the autumn season.

The severity of croup can be graded based on the presence of symptoms such as stridor, cough, and respiratory distress. Mild cases may only have occasional barking cough and no audible stridor at rest, while severe cases may have frequent barking cough, prominent inspiratory stridor at rest, and marked sternal wall retractions. Children with moderate or severe croup, those under 6 months of age, or those with known upper airway abnormalities should be admitted to the hospital.

Diagnosis of croup is usually made based on clinical presentation, but a chest x-ray may show subglottic narrowing, commonly referred to as the steeple sign. Treatment for croup typically involves a single dose of oral dexamethasone or prednisolone, regardless of severity. In emergency situations, high-flow oxygen and nebulized adrenaline may be necessary.

Understanding croup is important for parents and healthcare providers alike, as prompt recognition and treatment can help prevent complications and improve outcomes for affected children.

Transient synovitis, also known as irritable hip, is a common childhood condition that presents with sudden onset pain and limping. It is diagnosed by ruling out other possible causes and typically resolves on its own within 1-2 weeks. While trauma or non-accidental injury may be a factor, this would likely be revealed in the patient’s medical history. However, doctors should remain vigilant for signs of non-accidental injury. Although septic arthritis is a possibility, it is unlikely in cases where blood tests are normal. Slipped Upper Femoral Epiphysis (SUFE), which causes groin pain and a waddling gait, can be ruled out based on its characteristic x-ray findings.

Transient synovitis, also known as irritable hip, is a common cause of hip pain in children aged 3-8 years. It typically occurs following a recent viral infection and presents with symptoms such as groin or hip pain, limping or refusal to weight bear, and occasionally a low-grade fever. However, a high fever may indicate other serious conditions such as septic arthritis, which requires urgent specialist assessment. To exclude such diagnoses, NICE Clinical Knowledge Summaries recommend monitoring children in primary care with a presumptive diagnosis of transient synovitis, provided they are aged 3-9 years, well, afebrile, mobile but limping, and have had symptoms for less than 72 hours. Treatment for transient synovitis involves rest and analgesia, as the condition is self-limiting.

If a child shows a preference for one hand before the age of 12 months, it may be a sign of cerebral palsy and should be addressed promptly. The appropriate course of action is to refer the child to a child development service for a comprehensive evaluation by a multidisciplinary team. Children with cerebral palsy typically receive specialized care from birth, but in some cases, the condition may be suspected in a primary care setting. According to NICE guidelines, delayed motor milestones such as not sitting by 8 months (adjusted for gestational age), not walking by 18 months (adjusted for gestational age), early asymmetry of hand function, and persistent toe-walking may indicate cerebral palsy. In this case, as the child is exhibiting hand preference before the age of 1 year and has a risk factor for cerebral palsy (low birth weight), an urgent referral is necessary. Other options are not appropriate and may delay diagnosis and treatment.

Common Developmental Problems and Possible Causes

Developmental problems can manifest in various ways, including referral points such as not smiling at 10 weeks, inability to sit unsupported at 12 months, and failure to walk at 18 months. Fine motor skill problems may also arise, such as abnormal hand preference before 12 months, which could indicate cerebral palsy. Gross motor problems are often caused by a variant of normal, cerebral palsy, or neuromuscular disorders like Duchenne muscular dystrophy. Speech and language problems should always be checked for hearing issues, as they can also be caused by environmental deprivation or general development delay.

It is important to recognize these developmental problems early on and seek appropriate interventions to address them. By doing so, children can receive the necessary support to reach their full potential and overcome any challenges they may face. With proper care and attention, many children with developmental problems can go on to lead happy and fulfilling lives.

Distinguishing between respiratory illnesses in children: A guide

When a child presents with respiratory symptoms, it can be difficult to determine the underlying cause. Here, we will discuss the key features of several common respiratory illnesses in children and how to differentiate between them.

Bronchiolitis is characterized by coryzal symptoms followed by a persistent cough, tachypnea, chest recession, and wheezing or crepitations on auscultation. A low-grade fever and reduced feeding may also be present.

Croup is a viral upper airway infection that causes a barking cough, predominantly inspiratory stridor, hoarse voice, intercostal or sternal indrawing, fever, and coryzal symptoms.

Asthma typically presents with shortness of breath, cough, wheeze, and chest tightness, and is more common in children over two years old.

Acute epiglottitis is an insidious but rapidly progressive airway emergency that causes fever, sore throat, odynophagia, muffled voice, dysphagia, dyspnea, respiratory distress, dysphonia, and stridor. The child may sit in a tripod position to maximize airway opening.

A viral upper respiratory tract infection may cause coryzal symptoms, cough, and fever, but crepitations on auscultation would not be expected.

By understanding the key features of these respiratory illnesses, healthcare providers can make a more accurate diagnosis and provide appropriate treatment.

Understanding Genetic Conditions: Trisomy 18 (Edwards’ Syndrome)

Trisomy 18, also known as Edwards’ syndrome, is a genetic condition that results in a range of physical and developmental abnormalities. Neonates with trisomy 18 often present with neonatal hypotonia, apnoea, and seizures, as well as severe psychomotor and growth retardation. Other common features include microcephaly, microphthalmia, microstomia, micrognathia, clenched fingers, and rocker-bottom feet. Over 90% of individuals with trisomy 18 have cardiac defects, commonly ventricular septal defect (VSD), as well as anomalies in most organ systems. Unfortunately, many fetuses will die in utero, and neonates born with trisomy 18 have a 40% chance of survival to 1 month.

It is important to note that an Edwards’ syndrome diagnosis should be made in the prenatal period. Low levels of AFP (α-fetoprotein), estradiol, and hCG (human chorionic gonadotrophin) on triple test biochemistry are suggestive, and the diagnosis can be confirmed on ultrasonography.

Other genetic conditions, such as Pierre-Robin syndrome, Down’s syndrome, Fragile X syndrome, and Noonan’s syndrome, have their own distinct features and should be differentiated from trisomy 18. Understanding these conditions and their unique characteristics can aid in early diagnosis and appropriate management.

Management of Fever in a High-Risk Child

When managing a child with fever, it is important to consider their age and any accompanying symptoms. According to the NICE guideline on ‘Fever in under 5s’, children aged <3 months with a temperature of 38°C are at high risk for serious illness. In such cases, it is recommended to refer the child urgently to a paediatric specialist. Encouraging fluids may be useful, but it should not be relied upon to rule out serious underlying illness. Similarly, antipyretics may be given before the child is seen by the paediatric team, but it is important to consult the NICE guideline for appropriate dosages. Blind prescription of oral antibiotics or IM benzylpenicillin is not recommended without a clear source of infection and discussion with the on-call paediatric team. Therefore, it is crucial to refer high-risk children to the paediatric on-call team for further management.

Breastfed infants may be susceptible to vitamin K deficiency, as breast milk lacks sufficient amounts of this nutrient. The baby in question is likely experiencing idiopathic vitamin K deficiency, with breastfeeding being the only known risk factor. It is possible that the baby did not receive a vitamin K injection at birth, as they were born in Ukraine. Gender, age, vaginal delivery, and birth order are not associated with an increased risk of vitamin K deficiency.

Haemorrhagic Disease of the Newborn: Causes and Prevention

Newborn babies have a relatively low level of vitamin K, which can lead to the development of haemorrhagic disease of the newborn (HDN). This condition occurs when the production of clotting factors is impaired, resulting in bleeding that can range from minor bruising to intracranial haemorrhages. Breast-fed babies are particularly at risk, as breast milk is a poor source of vitamin K. Additionally, the use of antiepileptic medication by the mother can increase the risk of HDN in the newborn.

To prevent HDN, all newborns in the UK are offered vitamin K supplementation. This can be administered either intramuscularly or orally. By providing newborns with adequate levels of vitamin K, the risk of HDN can be significantly reduced. It is important for parents and healthcare providers to be aware of the risk factors for HDN and to take steps to prevent this potentially serious condition.

Reassurance and advice can be provided to manage nocturnal enuresis in children under the age of 5 years.

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.

When dealing with precocious puberty, it is important to examine the size of the testicles to determine the underlying cause. In cases where the testicles are small, such as in this situation, it suggests an adrenal origin of the symptoms. On the other hand, if there is bilateral testicular enlargement, it may indicate central precocious puberty caused by an astrocytoma or other brain tumor. Testotoxicosis, which is associated with a history of childhood sexual aggression, would result in advanced development in all areas. A sex cord-gonadal stromal tumor would cause unilateral enlargement of the affected testicle. Finally, an idiopathic cause of precocious puberty would lead to advanced development in all pubertal areas, resulting in enlarged testicles.

Understanding Precocious Puberty

Precocious puberty is a condition where secondary sexual characteristics develop earlier than expected, before the age of 8 in females and 9 in males. It is more common in females and can be classified into two types: gonadotrophin dependent and gonadotrophin independent. The former is caused by premature activation of the hypothalamic-pituitary-gonadal axis, resulting in raised levels of FSH and LH. The latter is caused by excess sex hormones, with low levels of FSH and LH. In males, precocious puberty is uncommon and usually has an organic cause, such as gonadotrophin release from an intracranial lesion, gonadal tumour, or adrenal cause. In females, it is usually idiopathic or familial and follows the normal sequence of puberty. Organic causes are rare and associated with rapid onset, neurological symptoms and signs, and dissonance, such as in McCune Albright syndrome. Understanding precocious puberty is important for early detection and management of the condition.

Scarlet Fever: Symptoms, Causes, and Treatment

Scarlet fever is a bacterial infection caused by toxin-producing strains of the group A streptococcal bacterium (Streptococcus pyogenes). It is a notifiable disease to Public Health England. The symptoms include a sore throat, fever, and a rash with a red strawberry tongue, cervical lymphadenopathy, fine papular rash, tonsillitis, tiredness, headache, nausea, and vomiting.

The condition is treated with fluids, an antipyretic, and phenoxymethylpenicillin. Other causes such as Influenza pneumoniae, Escherichia coli, Haemophilus influenzae, and Parvovirus B19 are not related to scarlet fever. It is important to seek medical attention if you suspect you or your child has scarlet fever.

The initial management for duct dependent congenital heart disease involves maintaining the ductus arteriosus with prostaglandins. In neonates with transposition of the great arteries (TGA), prostaglandin E1 is given intravenously to ensure the ductus arteriosus remains open, as its closure can lead to circulatory failure and profound cyanosis. Prostaglandins work by dilating vascular smooth muscle, which maintains the patency of the ductus arteriosus. Administering prostaglandins after delivery is necessary as the prostaglandin-rich placenta is no longer present to keep the ductus arteriosus open. Adenosine is not indicated in this case, as the newborn’s issue is circulatory rather than related to cardiac electrical activity. If heart failure occurs, angiotensin-converting enzyme (ACE) inhibitors may be used, but prostaglandins should be the first-line treatment to prevent heart failure. Non-steroidal anti-inflammatory drugs (NSAIDs) should be avoided as they inhibit prostaglandin synthesis, leading to closure of the ductus arteriosus and likely death of the newborn. Prostaglandin E is the most potent type of prostaglandin responsible for maintaining ductus arteriosus patency, not prostaglandin F2.

Understanding Transposition of the Great Arteries

Transposition of the great arteries (TGA) is a type of congenital heart disease that results in a lack of oxygenated blood flow to the body. This condition occurs when the aorticopulmonary septum fails to spiral during septation, causing the aorta to leave the right ventricle and the pulmonary trunk to leave the left ventricle. Children born to diabetic mothers are at a higher risk of developing TGA.

The clinical features of TGA include cyanosis, tachypnea, a loud single S2 heart sound, and a prominent right ventricular impulse. Chest x-rays may show an egg-on-side appearance.

To manage TGA, it is important to maintain the ductus arteriosus with prostaglandins. Surgical correction is the definitive treatment for this condition. Understanding the basic anatomical changes and clinical features of TGA can help with early diagnosis and appropriate management.

Edward’s syndrome is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers. The baby affected by this syndrome will have experienced slow growth in the womb and will have a low birthweight. Unfortunately, around half of those who survive to birth will pass away within two weeks, and only one in every five will live for at least three months. The survival rate beyond one year is only one in every 12 babies born with Edwards’ syndrome. This information is according to NHS Choices.

Childhood syndromes are a group of medical conditions that affect children and are characterized by a set of common features. Patau syndrome, also known as trisomy 13, is a syndrome that is characterized by microcephaly, small eyes, cleft lip/palate, polydactyly, and scalp lesions. Edward’s syndrome, also known as trisomy 18, is characterized by micrognathia, low-set ears, rocker bottom feet, and overlapping of fingers. Fragile X syndrome is characterized by learning difficulties, macrocephaly, long face, large ears, and macro-orchidism. Noonan syndrome is characterized by a webbed neck, pectus excavatum, short stature, and pulmonary stenosis. Pierre-Robin syndrome is characterized by micrognathia, posterior displacement of the tongue, and cleft palate. Prader-Willi syndrome is characterized by hypotonia, hypogonadism, and obesity. William’s syndrome is characterized by short stature, learning difficulties, friendly, extrovert personality, and transient neonatal hypercalcaemia. Cri du chat syndrome, also known as chromosome 5p deletion syndrome, is characterized by a characteristic cry, feeding difficulties and poor weight gain, learning difficulties, microcephaly and micrognathism, and hypertelorism. It is important to note that Treacher-Collins syndrome is similar to Pierre-Robin syndrome, but it is autosomal dominant and usually has a family history of similar problems.

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

Understanding Microcephaly: Causes and Definitions

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

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

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

For children without a penicillin allergy, amoxicillin is the primary treatment for pneumonia according to the 2011 guidelines from the British Thoracic Society. If the initial treatment is ineffective, macrolides may be added. Macrolides are recommended if Mycoplasma or Chlamydia is suspected. Co-amoxiclav is suggested for pneumonia associated with influenza.

Pneumonia is a common illness in children, with S. pneumoniae being the most likely cause of bacterial pneumonia. The British Thoracic Society has published guidelines for the management of community acquired pneumonia in children. According to these guidelines, amoxicillin is the first-line treatment for all children with pneumonia. Macrolides may be added if there is no response to first-line therapy, or if mycoplasma or chlamydia is suspected. In cases of pneumonia associated with influenza, co-amoxiclav is recommended. It is important to follow these guidelines to ensure effective treatment and management of pneumonia in children.

Exposed bowel in babies with gastroschisis leads to a considerable loss of fluid and heat, which can pose a serious risk to their lives. Unlike exomphalos, gastroschisis is not associated with cardiac and renal issues. Additionally, there is no correlation between gastroschisis and microcephaly or macrocephaly.

Gastroschisis and exomphalos are both types of congenital visceral malformations. Gastroschisis refers to a defect in the anterior abdominal wall located just beside the umbilical cord. In contrast, exomphalos, also known as omphalocoele, involves the protrusion of abdominal contents through the anterior abdominal wall, which are covered by an amniotic sac formed by amniotic membrane and peritoneum.

When it comes to managing gastroschisis, vaginal delivery may be attempted, but newborns should be taken to the operating theatre as soon as possible after delivery, ideally within four hours. As for exomphalos, a caesarean section is recommended to reduce the risk of sac rupture. In cases where primary closure is difficult due to lack of space or high intra-abdominal pressure, a staged repair may be undertaken. This involves allowing the sac to granulate and epithelialise over several weeks or months, forming a shell. As the infant grows, the sac contents will eventually fit within the abdominal cavity, at which point the shell can be removed and the abdomen closed.

Overall, both gastroschisis and exomphalos require careful management to ensure the best possible outcome for the newborn. By understanding the differences between these two conditions and the appropriate steps to take, healthcare professionals can provide effective care and support to both the infant and their family.

Meningitis poses a higher risk to neonates, particularly those with low birth weight, prematurity, traumatic delivery, fetal hypoxia, and maternal peripartum infection. The initial symptoms are usually vague and may include elevated body temperature, respiratory distress, apnea, episodes of bradycardia, low blood pressure, difficulty feeding, irritability, and decreased activity.

Organisms causing meningitis in children

Meningitis is a serious condition that can affect children of all ages. The organisms that cause meningitis vary depending on the age of the child. In neonates up to 3 months old, Group B Streptococcus is the most common cause, which is usually acquired from the mother during birth. E. coli and other Gram-negative organisms, as well as Listeria monocytogenes, can also cause meningitis in this age group.

From 1 month to 6 years old, Neisseria meningitidis (meningococcus), Streptococcus pneumoniae (pneumococcus), and Haemophilus influenzae are the most common organisms that cause meningitis. In children over 6 years old, Neisseria meningitidis and Streptococcus pneumoniae are the most common causes.

It is important for parents to be aware of the signs and symptoms of meningitis, such as fever, headache, stiff neck, and sensitivity to light. If a child is showing these symptoms, they should be taken to a doctor immediately for evaluation and treatment. Early diagnosis and treatment can help prevent serious complications and improve outcomes.

Trinucleotide repeat disorders exhibit earlier onset in successive generations due to anticipation, which is often accompanied by an escalation in symptom severity.

Trinucleotide repeat disorders are genetic conditions that occur due to an abnormal number of repeats of a repetitive sequence of three nucleotides. These expansions are unstable and can enlarge, leading to an earlier age of onset in successive generations, a phenomenon known as anticipation. In most cases, an increase in the severity of symptoms is also observed. It is important to note that these disorders are predominantly neurological in nature.

Examples of trinucleotide repeat disorders include Fragile X, Huntington’s, myotonic dystrophy, Friedreich’s ataxia, spinocerebellar ataxia, spinobulbar muscular atrophy, and dentatorubral pallidoluysian atrophy. Friedreich’s ataxia is unique in that it does not demonstrate anticipation.

Diagnostic Tests for Haemophilia: Factor VIII Assay, Prothrombin Time/INR, Platelet Count, Bone Marrow Examination, and Blood Film

Haemophilia is an X-linked bleeding disorder caused by deficiency of clotting factor VIII (haemophilia A) or factor IX (haemophilia B). Patients may present with bruising, inadequate clotting with mild injury, or spontaneous haemorrhage. To diagnose haemophilia A, a factor VIII assay is necessary. Other diagnostic tests include prothrombin time/INR, platelet count, bone marrow examination, and blood film. The prothrombin time and platelet count are normal in haemophilia, while bone marrow sampling carries a risk of significant bleeding. A blood film is not useful in the diagnosis as red blood cells and platelet count are normal.

Management of Acute Epiglottitis

Acute epiglottitis is a medical emergency that requires prompt management to prevent airway obstruction. It is caused by inflammation of the epiglottis and is most common in children. Symptoms include fever, sore throat, difficulty swallowing, and respiratory distress. The most severe cases can lead to complete airway obstruction, which can be fatal.

The most important initial step in management is to call for an anaesthetist to intubate the child. Attempting to administer treatment via a facemask or examining the child’s throat can cause distress and increase the risk of complete airway obstruction. The anaesthetist should be present during any examination or treatment to ensure the safety of the child.

In summary, acute epiglottitis is a medical emergency that requires prompt management to prevent airway obstruction. Calling for an anaesthetist to intubate the child is the most important initial step in management. Any examination or treatment should be done with the anaesthetist present to ensure the safety of the child.

Coarctation of the aorta does not cause cyanosis.

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.

Understanding Nephrotic Syndrome in Children

Nephrotic syndrome is a medical condition that is characterized by three main symptoms: proteinuria, hypoalbuminaemia, and oedema. This condition is most commonly seen in children between the ages of 2 and 5 years old. In fact, around 80% of cases in children are caused by a condition called minimal change glomerulonephritis. Fortunately, this condition has a good prognosis, with approximately 90% of cases responding well to high-dose oral steroids.

Aside from the main symptoms, children with nephrotic syndrome may also experience hyperlipidaemia, a hypercoagulable state, and a higher risk of infection. These additional features are caused by the loss of antithrombin III and immunoglobulins in the body.

Overall, understanding nephrotic syndrome in children is important for parents and healthcare professionals alike. With proper treatment and management, most children with this condition can recover and lead healthy lives.

Formula options for infants with different types of intolerance vary. For infants with cow’s milk protein intolerance, a partially hydrolysed formula is recommended as it contains proteins that are less allergenic. Amino acid-based formula is suitable for infants with severe intolerance, although it may not be as palatable. High protein formula is used for pre-term infants, but recent studies suggest that it may increase the risk of obesity in the long-term. Lactose-free formula is appropriate for infants with lactose intolerance, which is characterized by gastrointestinal symptoms rather than rash and runny nose.

Understanding Cow’s Milk Protein Intolerance/Allergy

Cow’s milk protein intolerance/allergy (CMPI/CMPA) is a condition that affects around 3-6% of children, typically presenting in the first 3 months of life in formula-fed infants. Both immediate and delayed reactions can occur, with CMPA used for immediate reactions and CMPI for mild-moderate delayed reactions. Symptoms include regurgitation, vomiting, diarrhea, urticaria, atopic eczema, colic symptoms, wheeze, chronic cough, and rarely, angioedema and anaphylaxis. Diagnosis is often clinical, with investigations including skin prick/patch testing and total IgE and specific IgE (RAST) for cow’s milk protein.

Management for formula-fed infants includes using extensive hydrolyzed formula (eHF) milk as the first-line replacement formula for mild-moderate symptoms and amino acid-based formula (AAF) for severe CMPA or if no response to eHF. Around 10% of infants are also intolerant to soya milk. For breastfed infants, mothers should eliminate cow’s milk protein from their diet and consider prescribing calcium supplements to prevent deficiency. eHF milk can be used when breastfeeding stops until at least 6 months and up to 12 months of age.

The prognosis for CMPI is usually good, with most children becoming milk tolerant by the age of 3-5 years. However, a challenge is often performed in a hospital setting as anaphylaxis can occur. It is important to refer infants with severe symptoms to a pediatrician for management. Understanding CMPI/CMPA and its management can help parents and healthcare providers provide appropriate care for affected children.

Admission to the paediatric ward is necessary when a child presents with audible stridor at rest, which is a clear indication of croup. This condition is characterized by a barking cough, mild fever, and coryzal symptoms, and in moderate cases, suprasternal wall retraction may be observed. Discharging the patient with dexamethasone or antibiotics is not appropriate, as stridor at rest requires further observation. A single dose of oral dexamethasone should be administered to all children with croup, regardless of severity. Referral to ENT is not urgent and not necessary in this case.

Understanding Croup: A Respiratory Infection in Infants and Toddlers

Croup is a type of upper respiratory tract infection that commonly affects infants and toddlers. It is characterized by a barking cough, fever, and coryzal symptoms, and is caused by a combination of laryngeal oedema and secretions. Parainfluenza viruses are the most common cause of croup. The condition typically peaks between 6 months and 3 years of age, and is more prevalent during the autumn season.

The severity of croup can be graded based on the presence of symptoms such as stridor, cough, and respiratory distress. Mild cases may only have occasional barking cough and no audible stridor at rest, while severe cases may have frequent barking cough, prominent inspiratory stridor at rest, and marked sternal wall retractions. Children with moderate or severe croup, those under 6 months of age, or those with known upper airway abnormalities should be admitted to the hospital.

Diagnosis of croup is usually made based on clinical presentation, but a chest x-ray may show subglottic narrowing, commonly referred to as the steeple sign. Treatment for croup typically involves a single dose of oral dexamethasone or prednisolone, regardless of severity. In emergency situations, high-flow oxygen and nebulized adrenaline may be necessary.

Understanding croup is important for parents and healthcare providers alike, as prompt recognition and treatment can help prevent complications and improve outcomes for affected children.

Perthes’ Disease: Avascular Necrosis of the Proximal Femoral Head in Children

Perthes’ disease is a condition that results from avascular necrosis of the proximal femoral head, which is caused by a compromised blood supply. It typically affects children aged 4-10, with boys being affected more frequently than girls. The disease presents with a painless limp and limited range of motion of the affected hip, followed by hip pain as necrosis develops.

The diagnosis of Perthes’ disease is suspected clinically, and radiographs may be normal initially or show only a non-specific effusion. As the condition progresses, the joint space between the ossified femoral head and acetabulum widens, and narrowing or collapse of the femoral head causes it to appear widened and flattened. Eventually, femoral head collapse may ensue.

Other conditions that may present similarly to Perthes’ disease include slipped upper femoral epiphysis, septic arthritis, juvenile rheumatoid arthritis, and congenital dislocation of the hip. However, each of these conditions has its own unique features and diagnostic criteria.

Overall, Perthes’ disease is a generalised disorder of cartilage development that predisposes children to repeated episodes of infarction in the proximal femoral epiphysis. The most significant factors determining prognosis are onset in the older child, epiphyseal protrusion, extensive involvement of the epiphysis, and arrest of subcapital growth.
