Developmental Delay in Children

Developmental delay in children can be a cause for concern, especially when they fail to meet certain milestones at their age. For instance, a 4-year-old child should be able to speak in full sentences, play interactively, and build structures with building blocks. However, when a child exhibits a degree of developmental delay, it could be due to various factors such as neurological and neurodevelopmental problems like cerebral palsy and epilepsy, unmet physical and psychological needs, sensory impairment, genetic conditions like Down’s syndrome, and ill health.

It is important to understand the causes of developmental delay in children to provide appropriate interventions and support. Parents and caregivers should observe their child’s development and seek professional help if they notice any delays or abnormalities. Early intervention can help address developmental delays and improve a child’s overall well-being. By the factors that contribute to developmental delay, we can work towards creating a supportive environment that promotes healthy growth and development in children.

If a patient presents with whooping cough within 21 days of the onset of cough, they should be prescribed either azithromycin or clarithromycin. In this case, the correct option is to prescribe oral clarithromycin. Hospital admission for IV antibiotics is not necessary as the patient is stable. If the patient had presented after three weeks, advice would be the appropriate course of action. Oral co-amoxiclav and oral doxycycline are not recommended treatments for whooping cough.

Whooping Cough: Causes, Symptoms, Diagnosis, and Management

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

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

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

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

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

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

Pediatric Wheezing: Causes and Characteristics

Pediatric wheezing can be caused by various conditions, each with its own unique characteristics. Unilateral wheeze in a child under three years old is often associated with inhalation of a foreign body, which can partially or completely obstruct the airway. Bronchiolitis, typically caused by respiratory syncytial virus, initially presents as an upper respiratory tract infection and progresses to a lower respiratory tract infection with bilateral wheeze, cough, and difficulty breathing. Pneumonia may also cause wheezing, but is typically accompanied by systemic symptoms such as fever and crepitations on auscultation. Asthma, a common cause of pediatric wheezing, is characterized by bilateral expiratory wheezing due to premature bronchiole collapse. Croup, caused by a parainfluenza virus, presents with a barking cough, stridor, and respiratory distress, and is treated with dexamethasone.

Neonatal Resuscitation Guidelines for Heart Rate and Ventilation

In neonatal resuscitation, it is important to follow guidelines for heart rate and ventilation to ensure the best possible outcome for the baby. Here are the guidelines for different scenarios:

– After a total of ten inflation breaths and 30 seconds of effective ventilation breaths if the baby’s heart rate is < 60 bpm: Chest compressions are indicated at a ratio of 3:1 (compression:ventilation). The heart rate should be checked every 30 seconds. If the heart rate is not detectable or very slow (<60), consider venous access and drugs.
– After ten inflation breaths if the baby’s heart rate is < 120 bpm: Give 30 seconds of effective ventilation breaths before starting compressions if the heart rate is < 60 bpm.
– After five inflation breaths if the baby is not spontaneously breathing: Ventilate for 30 seconds before starting compressions, unless there is an underlying cardiac cause for the cardiorespiratory arrest.
– After ten inflation breaths and two minutes of effective ventilation breaths if the baby’s heart rate is < 60 bpm: This scenario is not applicable as compressions should have been started after the initial 30 seconds of ventilation.
– Before any inflation breaths if the baby’s heart rate is < 60 bpm: Give 30 seconds of effective ventilation breaths before starting compressions if ten inflation breaths are not successful and the heart rate is still < 60 bpm.

This presentation may indicate the possibility of pyloric stenosis, as there are signs of visible peristalsis where the stomach is attempting to move its contents past the obstruction. The vomiting is non-bilious, which suggests that the obstruction is located before the second part of the duodenum where bile enters the digestive system. This is different from malrotation and duodenal atresia.

Understanding Pyloric Stenosis

Pyloric stenosis is a condition that usually occurs in infants between the second and fourth weeks of life. However, in rare cases, it may present later, up to four months. This condition is caused by the thickening of the circular muscles of the pylorus. Pyloric stenosis is more common in males, with an incidence of 4 per 1,000 live births. It is also more likely to affect first-borns and infants with a positive family history.

The most common symptom of pyloric stenosis is projectile vomiting, which usually occurs about 30 minutes after a feed. Other symptoms may include constipation, dehydration, and a palpable mass in the upper abdomen. Prolonged vomiting can lead to hypochloraemic, hypokalaemic alkalosis, which can be life-threatening.

Diagnosis of pyloric stenosis is typically made using ultrasound. Management of this condition involves a surgical procedure called Ramstedt pyloromyotomy. This procedure involves making a small incision in the pylorus to relieve the obstruction and allow for normal passage of food. With prompt diagnosis and treatment, infants with pyloric stenosis can make a full recovery.

Urinary tract infections (UTI) are more common in boys until 3 months of age, after which the incidence is substantially higher in girls. Presentation in childhood depends on age, with infants showing poor feeding, vomiting, and irritability, younger children showing abdominal pain, fever, and dysuria, and older children showing dysuria, frequency, and haematuria. NICE guidelines recommend checking urine samples in children with symptoms or signs suggestive of a UTI, unexplained fever of 38°C or higher, or an alternative site of infection but who remain unwell. Urine collection should be done through clean catch or urine collection pads, and invasive methods should only be used if non-invasive methods are not possible. Management includes referral to a paediatrician for infants less than 3 months old, admission to hospital for children aged more than 3 months old with an upper UTI, and oral antibiotics for 3-10 days for children aged more than 3 months old with a lower UTI. Antibiotic prophylaxis is not given after the first UTI but should be considered with recurrent UTIs.

Immediate admission would be necessary for a heart rate of 200bpm. A heart rate of 160 bpm would be worrisome and hospital evaluation should be contemplated, but the urgency would vary based on the patient’s clinical state.

Bronchiolitis is a condition where the bronchioles become inflamed, and it is most commonly caused by respiratory syncytial virus (RSV). This virus is responsible for 75-80% of cases, with other causes including mycoplasma and adenoviruses. Bronchiolitis is most prevalent in infants under one year old, with 90% of cases occurring in those aged 1-9 months. The condition is more serious in premature babies, those with congenital heart disease or cystic fibrosis. Symptoms include coryzal symptoms, dry cough, increasing breathlessness, and wheezing. Hospital admission is often necessary due to feeding difficulties associated with increasing dyspnoea.

Immediate referral is recommended if the child has apnoea, looks seriously unwell, has severe respiratory distress, central cyanosis, or persistent oxygen saturation of less than 92% when breathing air. Clinicians should consider referral if the child has a respiratory rate of over 60 breaths/minute, difficulty with breastfeeding or inadequate oral fluid intake, or clinical dehydration. Immunofluorescence of nasopharyngeal secretions may show RSV, and management is largely supportive. Humidified oxygen is given via a head box if oxygen saturations are persistently low, and nasogastric feeding may be necessary if children cannot take enough fluid/feed by mouth. Suction may also be used for excessive upper airway secretions. NICE released guidelines on bronchiolitis in 2015 for more information.

An amber flag (intermediate risk) on the traffic light system indicates that the patient is on room air. For infants aged 12 months or older, a respiratory rate of over 40 breaths per minute would also be considered an amber flag, but not for a 6-12-month-old in this particular case.

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.

When a newborn baby’s hearing test at birth shows an abnormal result, they are offered an auditory brainstem response test as a follow-up. This test involves placing electrodes on the baby’s scalp to measure their auditory evoked potentials in response to sounds. If there is no response, it may indicate reduced hearing ability.

It is not appropriate to use a distraction test on a newborn as they are not yet developed enough for this type of testing. This test is typically used for toddlers aged 6-9 months and requires two staff members. The test involves producing sounds to the right or left of the baby, out of their field of view, and assessing the loudness required for them to react.

Newborn otoacoustic emission testing is the initial screening assessment for hearing in newborns. However, this is only a screening test and further investigations are required to confirm any hearing loss. The test works by generating a click sound through an earpiece and measuring for the presence of a soft echo, which indicates a healthy cochlea.

Pure tone audiometry is not an appropriate second-line hearing investigation for newborns. This test requires the participant to indicate when they hear specific sounds and is typically used in school-aged children. Therefore, it is not useful for newborns.

Hearing Tests for Children

Hearing tests are important for children to ensure that they are developing normally. There are several tests that may be performed on children of different ages. For newborns, an otoacoustic emission test is typically done as part of the Newborn Hearing Screening Programme. This test involves playing a computer-generated click through a small earpiece and checking for the presence of a soft echo, which indicates a healthy cochlea. If the results of this test are abnormal, an Auditory Brainstem Response test may be done.

For infants between 6-9 months, a Distraction test may be performed by a health visitor with the help of two trained staff members. For children between 18 months to 2.5 years, a Recognition of familiar objects test may be used, which involves using familiar objects like a teddy or cup and asking the child simple questions like where is the teddy? For children over 2.5 years, Performance testing and Speech discrimination tests may be used, such as the Kendall Toy test or McCormick Toy Test. Pure tone audiometry is typically done at school entry in most areas of the UK for children over 3 years old.

In addition to these tests, there is also a questionnaire for parents in the Personal Child Health Records called Can your baby hear you? It is important for parents to be aware of these tests and to have their child’s hearing checked regularly to ensure proper development.

Assessing Acute Asthma Attacks in Children

When assessing the severity of asthma attacks in children, the 2016 BTS/SIGN guidelines recommend using specific criteria. These criteria can help determine whether the attack is severe or life-threatening. For a severe attack, the child may have a SpO2 level below 92%, a PEF level between 33-50% of their best or predicted, and may be too breathless to talk or feed. Additionally, their heart rate may be over 125 (for children over 5 years old) or over 140 (for children between 1-5 years old), and their respiratory rate may be over 30 breaths per minute (for children over 5 years old) or over 40 (for children between 1-5 years old). They may also be using accessory neck muscles to breathe.

For a life-threatening attack, the child may have a SpO2 level below 92%, a PEF level below 33% of their best or predicted, and may have a silent chest, poor respiratory effort, agitation, altered consciousness, or cyanosis. It is important for healthcare professionals to be aware of these criteria and to take appropriate action to manage the child’s asthma attack. By following these guidelines, healthcare professionals can help ensure that children with asthma receive the appropriate care and treatment they need during an acute attack.
