Barking cough without prominent stridor and raised temperature describes what condition?
Croup
Barking cough with biphasic stridor. Week of stability then rapid deterioration
Bacterial tracheitis
Snoring stridor, non-prominent cough, raised temp and drooling.
Epiglottis
How do you manage a child with croup-like symptoms?
All
- Oral dexamethasone (0.15mg/kg)/oral prednisilone is alternative

- Admit
- Can give IM dexamethasone or neb budenoside as alternatives to oral drugs
- Nebulised adrenaline 5ml 1:5000
What circumstances would you admit someone with croup-like symptoms?
<6 months
Severe
Uncertainty about diagnosis
What causes bacterial tracheitis?
Staph aureus
How do you distinguish croup from whooping cough?
Croup: Barking cough
Whooping cough: Inspiratory whoop after cough.
–> Also vomiting and breathless spells
What gram negative coccobacillus is responsible for whooping cough?
B. pertussis
What is the treatment for whooping cough
If 21 days since the onset
Macrolide (<1yr: Clarithromycin, >1yr: erythromycin)
Co trimoxazole if macrolide not tolerated
Other than the patient, who else should receive antibiotics for whooping cough
Premature <32wks, non-immune/partially immune infants 32 wks
Pregnant women >=32 weeks
Those in a lot of contact with infants

Urgent if acute phase
Routine if later diagnosis

How:
1. Penicillin V
2. Clarithromycin
How do you treat quinsy?
Incision and drainage by ENT
What is the most common pathogen of pneumonia in children?
S. Pneumoniae (G+ve streptococcus)

Severe: Co-amox IV then PO 7 days total
Dry cough, wheeze and crackles following on from coryzal symptoms in a 3-6 month old suggests what condition paeds resp infection?
Bronchiolitis (although pretty non-specific tbf)
What is the most common cause of bronchiolitis? How is it treated
RSV
Supportive: Humidified 02 (if <92%)
NG tube if can’t feed
How to differentiate viral induced wheeze and asthma? How does their management differ?
Lack of atopic history in VIW
Management does not differ
Since they both present with recurrent chest infections, how can you clinically distinguish between cystic fibrosis and ciliary dyskinesia (Kartagener’s)?
CF: Salty sweat and GI problems (greasy stools, Hx meconium obstruction, failure to thrive)
CD: Situs inversus, recurrent sinusitis
What is the aetiology of CF? What are the chances of being born with CF?
Defect in Cl- channel due to AR mutation of CFTR gene
1/2500
How do you diagnose CF and CD?
CF: >60mmol/L on sweat test; antenatal/neonatal screening
CD: Bronchoscopy +biopsy
What is the treatment for chest infections in CF/CD?
Prophylactic
Oral flucloxacillin 3-6yrs old for staph aureus
Acute:
S. aureus: Treatment dose flucloxicillin
P. aeringuosa: ciprofloxacin, levofloxacin.
Chronic:
P. aeringuosa: Colistimethate –> aztreonam/tobramycin
What can be done to aid GI problems in CF?
High calorie diet, CREON tablets
Aside from resp and GI, what other counselling points must be given for CF?
Infertility
Reduced life expectancy (47yrs)
What are the red flags for neonatal sepsis?
Suspected sepsis in mother
Signs of Shock
Seizures
Resp distress > 4hrs after birth
Suspected sepsis in other baby if multiple
What are the risk factors for neonatal sepsis?
GBS colonisation/sepsis in previous pregnancy
Maternal sepsis, chorioamnionitis >38 degrees
<37 weeks
Premature rupture of membranes
Prolonged rupture of membrane
For neonatal sepsis when do you
Observe
Start Antibiotics
1 risk factor/feature = observe
>=2 factors/features = start abx
What Abx do you give in neonatal sepsis?
Penicillin + Aminoglycoside
eg benpen + gent
How do you provide further management in neonatal sepsis?
24hr CRP
36hrs Blood cultures
Consider stopping abx if well/results normal
