- Bacteria in CSF induce inflammatory cascade and leukocyte migration
- Results in cerebral oedema, raised ICP and neurological damage
- Can lead to Septic shock, DIC, renal and heart failure

Definition and Epidemiology of Measles
Definition:
• Measles is a highly infectious disease caused by the measles virus and characterised by a maculopapular rash, cough, coryza, conjunctiivtis and Koplikʼs spots
Epidemiology:
- Measles is ubiquitous in non-immunised populations, especially in developing worlds
- Highest incidence in children aged 5-9 years

Definition of Asthma
Definition:
- Chronic respiratory disorder characterised by variable airway inflammation, airway obstruction and airway hyper-responsiveness
- In older children and adults this may lead to permanent structural alterations of the airways (remodelling)

Definition and epidemiology of Bronchiolitis
Bronchiolitis:
Definition:
• Acute viral infection of the LRT characterised by obstruction of the small airways with air trapping
Epidemiology:
- < 2 years of age (most severe 1-2 months), leading cause of hospital admissions in this age group
- Uncommon in children < 1month or >2 years - Almost exclusively an infantile disease
- Seasonal – mainly winter
Risk factors for Bronchiolitis
Risk factors:
- < 3 years – lungs and immune system have not developed fully
- Winter months
- Premature birth - impaired lungs and immune system
- Underlying heart or lung condition - E.g. CF or congenital heart disease
- Passive smoking
- Infants with older siblings – bring the infection home
Aetiology and Pathophysiology of Bronchiolitis
Aetiology:
- RSV is the most common cause (>50%)
- Others: Parainfluenza virus and adenovirus
Pathophysiology:
- Virus infection of the respiratory epithelial cells causing necrosis, inflammation, oedema and mucous secretion/plugging
- Cellular destruction and inflammation leads to obstruction of the small airways
- Results in hyperinflation, cilia dysfunction, atelectasis and wheezing
- Re-growth of the epithelial cell layers does not occur until ~ 2 weeks post infection
Clinical features of Bronchiolitis
Clinical Features:
- Prodrome of 1-3 days of irritating cough, nasal congestion and rhinorrhoea
- Wheezing – due to airway narrowing with mucus and necrotic debris
- Fluctuating clinical findings – Hallmark of bronchiolitis
- ↑ WOB – Tachypnoea + grunting, nasal flaring, subcostal retraction (common)
- Fever > 38.5°C
- Apnoea may be presenting feature, especially in very young or premature or low birth weight infants (uncommon)
- Worst day 3-4
Investigations, management and prognosis of Bronchiolitis
Investigations:
• Clinical
Rx:
- Supportive
- Hospitalise with respiratory distress
- Donʼt use steroids
Prognosis:
- Most cases are mild and self-limiting (3-10 days)
- Most get better in 2-3weeks (when resp. epithelium regenerates)
- Only 1% require hospitalisation
Definition of Paediatric Pneumonia
Epidemiology of Paediatric Pneumonia
Epidemiology:
- Can occur at any age - but more common in children < 4 years
- Accounts for 13% of all infectious illnesses in infants < 2 years
- Cause of significant morbidity and mortality in developing countries
Aetiology of Paediatric Pneumonia
Risk Factors for Paediatric Pneumonia
Risk factors:
- Recent respiratory infection
- Bronchopulmonary dysplasia - chronic lung condition of infants born preterm
- CF
- Asthma
- Congenital heart disease
- Congenital and acquired immunodeficiency disorders
- Smoking

Definition and epidemiology of laryngotracheobronchitis (croup)
Laryngotracheobronchitis (croup)
Definition:
• Viral infection of the upper airways characterised by sudden onset seal-like barking cough, stridor, voice hoarseness and respiratory distress
Epidemiology:
- Most common cause of stridor in children 3 months – 5years
- Winter months
Aetiology and pathophysiology of laryngotracheobronchitis (croup)
Aetiology:
- Parainfluenza virus (1 or 3)
- RSV (common < 6 months + wheeze)
- Others: Adenovirus, Influenza A or B, Coronavirus
Pathophysiology:
- Upper airways obstruction caused by generalised inflammation and oedema of the airways
- Cellular level, necrosis and shedding of the epithelium
- Narrowed & subglottic inflammation is responsible for the seal-like barky cough and stridor
- If upper airways obstruction worsens it can lead to respiratory failure
