Pregnant women at 16-32 weeks are given the option to receive the pertussis vaccine.

Whooping Cough: Causes, Symptoms, Diagnosis, and Management

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

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

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

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

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

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

Children between the ages of 3 and 12 often experience growing pains, which typically involve leg pain. However, it is crucial to check for any potential warning signs when examining these children. One such warning sign is osteosarcoma, a rare but significant diagnosis that should be ruled out. Symptoms of osteosarcoma include an inexplicable lump, bone pain, or swelling. Another condition to consider is juvenile rheumatoid arthritis, which typically presents with fever, rash, and symmetrical joint pain and swelling.

Understanding Growing Pains in Children

Growing pains are a common complaint among children aged 3-12 years. These pains are often attributed to ‘benign idiopathic nocturnal limb pains of childhood’ in rheumatology, as they are not necessarily related to growth. Boys and girls are equally affected by growing pains, which are characterized by intermittent pain in the legs with no obvious cause.

One of the key features of growing pains is that they are never present at the start of the day after the child has woken up. Additionally, there is no limp or limitation of physical activity, and the child is systemically well with normal physical examination and motor milestones. Symptoms may worsen after a day of vigorous activity.

Overall, growing pains are a benign condition that can be managed with reassurance and simple measures such as massage or heat application. However, it is important to rule out other potential causes of leg pain in children, especially if there are any worrying features present.

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.

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 Necrotising Enterocolitis

Necrotising enterocolitis is a serious condition that is responsible for a significant number of premature infant deaths. The condition is characterized by symptoms such as feeding intolerance, abdominal distension, and bloody stools. If left untreated, these symptoms can quickly progress to more severe symptoms such as abdominal discolouration, perforation, and peritonitis.

To diagnose necrotising enterocolitis, doctors often use abdominal x-rays. These x-rays can reveal a number of important indicators of the condition, including dilated bowel loops, bowel wall oedema, and intramural gas. Other signs that may be visible on an x-ray include portal venous gas, pneumoperitoneum resulting from perforation, and air both inside and outside of the bowel wall. In some cases, an x-ray may also reveal air outlining the falciform ligament, which is known as the football sign.

Overall, understanding the symptoms and diagnostic indicators of necrotising enterocolitis is crucial for early detection and treatment of this serious condition. By working closely with healthcare professionals and following recommended screening protocols, parents and caregivers can help ensure the best possible outcomes for premature infants at risk for this condition.

The absence of the red-reflex may be a symptom of a congenital cataract, but this condition is typically identified at birth or during routine infant screenings. Additionally, a congenital cataract would not account for the familial history of enucleation.

Retinoblastoma is a prevalent type of eye cancer that is commonly found in children, with an average age of diagnosis at 18 months. It is caused by a loss of function of the retinoblastoma tumor suppressor gene on chromosome 13, which is inherited in an autosomal dominant pattern. About 10% of cases are hereditary. The most common presenting symptom is the absence of red-reflex, which is replaced by a white pupil (leukocoria). Other possible features include strabismus and visual problems.

When it comes to managing retinoblastoma, enucleation is not the only option. Depending on how advanced the tumor is, other treatment options include external beam radiation therapy, chemotherapy, and photocoagulation. The prognosis for retinoblastoma is excellent, with over 90% of patients surviving into adulthood.

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.

The Ortolani manoeuvre was performed on a newborn to relocate the femoral head after dislocation caused by the Barlow manoeuvre. The result was abnormal, indicating a need for urgent assessment to check for potential developmental dysplasia of the hip. The best imaging option is ultrasound, which avoids radiation and provides optimal visualization of the hip’s development. Referring the child for routine assessment would cause unnecessary delay in treatment, and providing reassurance would be inappropriate given the abnormal screening result.

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.

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

Understanding and Managing Constipation in Children

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

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

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

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

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.
