Human herpes virus 6 is the pathogen responsible for roseola
Roseola infantum, a common disease in children characterised by an initial high fever (which settles) but followed by a maculopapular rash.
It is caused by human herpes virus 6, what is the most common complication of this disease?
Febrile convulsions occur in up to 15% of children with the disease
Other than febrile convulsions, which is another recognised complication with human herpes virus 6 causing roseola infantum?
Meningitis
Orchitis is a common complication of:
mumps
mumps, a viral infection, usually presents with fever, malaise, muscular pain and parotitis
Sensorineural hearing loss is a common complication of:
bacterial menigitis
Sensorineural hearing loss is a common complication of:
bacterial meningitis
Otitis media is the most common complication following and which other long term complication:
-measles
Measles would present with conjunctivitis, fever, irritability, Koplik spots, as well as a rash which starts behind the ear before spreading to the whole body
Subacute sclerosing panencephalitis is a possible long-term complication, which can occur up to 10 years after initial measles infection.
A child who’s short of breath, used a salbutamol inhaler, and used a nebulised ipratropium bromide?
- The management of acute severe asthma is approached in a step-wise fashion
- Inhaled and nebulised salbutamol and nebulised ipratropium bromide should be tried before moving to intravenous salbutamol
At what stage of O2 sats would high flow oxygen be given to an asthmatic?
- Maintaining oxygen saturations of 96%, so unless oxygen saturations fall to <92%, there is no indication to give high flow oxygen
For the management of asthma, and if the O2 saturations <92% add magnesium sulphate?
If O2 saturations <92% add magnesium sulphate
If it’s severe or life-threatening acute asthma and it’s not responsive to inhaled therapy, what can be added?
aminophylline
Pneumothorax and anaphylaxis can be differentials for asthma, what would be the presentations?
- Pneumothorax and anaphylaxis will be very sudden onset (with pneumothorax being associated with chest pain and possible deviation of the trachea and anaphylaxis being associated with antigen exposure)
- Inhalation of a foreign body and pneumothorax will give unilateral chest signs and cardiac arrhythmia is suggested by chest pain or palpitations, tachycardia or changes in blood pressure
- Acute asthma is suggested by widespread wheeze, with exacerbation developing over minutes to hours and is confirmed by a reduced peak expiratory flow rate and FEV1 which improves with treatment
When will you consider adding nebulised Magnesium sulphate?
Unless oxygen saturations fall to <92%, there is no indication to add nebulised magnesium sulphate.
According to the British Thoracic Society guidelines, you should consider adding 150 mg magnesium sulphate to each nebulised salbutamol and ipratropium in the first hour in children with a short duration of acute severe asthma symptoms presenting with an SpO2 <92%
A child with persistent ductus arteriosus
(Treatment of a persistent ductus arteriosus is only required if the baby is symptomatic), what is the treatment?
About 1/3 of patients with a patent ductus arteriosus require medical treatment with indomethacin
Indomethacin is an NSAID that inhibits prostaglandin synthesis. Inhibition of prostaglandin causes vasoconstriction which closes the ductus arteriosus
A child with persistent ductus arteriosus
(Treatment of a persistent ductus arteriosus is only required if the baby is symptomatic), what is the treatment?
About 1/3 of patients with a patent ductus arteriosus require medical treatment with indomethacin
Indomethacin is an NSAID that inhibits prostaglandin synthesis. Inhibition of prostaglandin causes vasoconstriction which closes the ductus arteriosus

Blanching or non-blanching
Grey spots inside the cheeks are associated with what:
These are koplik’s spots (grey spots inside the cheeks) are associated with measles, but measles is a self-limiting illness with no specific treatment, it’s important to rule out any possible features of meningococcal illness first

Features of Gastro-oesophageal reflux in children?
As acid refluxes back up the oesophagus, babies commonly present with 4 features:
- Milky vomits after feeds.
- Crying/irritability
- Arching of the back
- Drawing up of the knees into the chest
A child of 6 months presents with milky vomits after feeding has a history and examination most consistent with what:
gastroesophageal reflux disease (GORD)
Vomiting after being laid flat and crying with arching of the back and drawing up the knees to the chest is characteristic of .
reflux
A child who’s been presenting with symptoms of reflux, and is well and has no signs of dehydration (moist mucous membranes, normal capillary refill time) and there are no red flags (normal blood gas, no palpable abdominal mass, no fever, no diarrhoea).
The chid is well, what safety netting advice should be given before being discharged?
Advice on conservative treatments (keep upright and burp after feeds, put their cot on slight incline) and infant gaviscon
Management of GORD in infants can be:
Conservative (advice on keeping baby upright and burping after feeds, put their cot on a slight incline for sleeping)
Medical (infant gaviscon, omeprazole)
Surgical in severe cases (fundoplication)
Which of the following is reserved for the treatment of severe episodes of this pt presentation with Tet spells?
Tet spells can be managed with analgesia and supplemental oxygen. A last line medication is a vasoconstrictive agent (e.g. phenylephrine). Vasoconstriction will help to increase systemic vascular resistance, reducing the right-to-left shunt and improving cyanosis.
LAST LINE: Phenylephrine (a vaso-constrictive agent) as a last line medical therapy
Vasoconstriction will help to increase systemic vascular resistance, reducing the right-to-left shunt and improving cyanosis
What is the surgical management of Tetralogy patients?
They will need definitive surgery to correct the ventricular septal defect and widen the right ventricular outflow tract
What are the features of patients with Tetralogy of Fallot?
Tetralogy of Fallot is a relatively rare form of congenital cardiac disease. The clinical features of Tetralogy of Fallot are:
- Pulmonary stenosis
- Right ventricular hypertrophy
- Overriding aorta
- Ventricular septal defect.
PROV
What happens during a tet spell?
Tetralogy of Fallot is most commonly diagnosed antenatally, or on detection of a murmur in the first few months of life. Babies can present with tet spells, which are acute episodes of cyanosis.
During a tet spell, pulmonary stenosis causes a right-to-left shunt of deoxygenated blood across the ventricular septal defect. This results in hypoxia, causing pain (inconsolable crying) and cyanosis.
What is used to stabilise the myocardium in severe hyperkalaemia?
Calcium gluconate
Common congenital heart disease in Down’s syndrome?
- ASDs and atrioventricular septal defects (AVSD) are a common type of congenital heart disease seen in patients with Down’s syndrome
- It causes an ejection systolic murmur at the upper left sternal edge
- The first heart sound is normal but there is wide fixed splitting of the second heart sound.
(VSDs are common in Down’s syndrome however they cause a pansystolic murmur heard in lower left sternal edge often all over the praecordium and do not usually radiate to the back
Also, the second heart sound is normal in VSD, but wide fixed splitting occurs in ASD)
What is the most common associated condition for Down syndrome?
Main concern is CHD risk
What are the three heart conditions associated with down syndrome?
Of these, atrioventricular septal defects (AVSD) are the most common, followed by ventricular septal defects (VSD)
Patients with trisomy 21 are also more likely to have a patent ductus arteriosus (PDA)
What is the most serious complication of untreated jaundice in babies?
Kernicterus is a rare but serious complication of untreated jaundice in babies
It’s caused by excess bilirubin damaging the brain or central nervous system
Treatment for kernicterus involves using an exchange transfusion.
When would you request an urgent chest x-ray for a baby presenting with jaundice?
There’s no infective respiratory cause of jaundice (e.g. Coughing, nasal flaring, cyanosis, etc.)
What days will breast feeding jaundice occur?
Between 2-14 days
A 27 day old neonate not feeding well. The baby is exclusively breast fed and has not had any problems with latching on before and previously was putting on weight.
The baby overall is jaundice and unwell, on examination, the baby looks jaundiced and is lethargic. The stool is of a normal colour and consistency. The mother says that there have been fewer wet nappies over the last 12 hours. There is some loss of skin turgor. There is no hepatomegaly on palpation of the abdomen.
- In a jaundiced unwell baby, sepsis is the first thing which has to be investigated due to the devastating consequences (organ failure, kernicterus, death)
- A urinary tract infection (UTI) is a common serious cause of jaundice in the newborn, and can often present with vague symptoms of lethargy or difficulty feeding
- UTI in a newborn is particularly serious as it can rapidly progress to sepsis.
- Remember to check glucose as hypo can be another sign of sepsis
What are the causes of jaundice of a baby less than 24 hrs?
Haemolytic disorders (Rh incompatibility, ABO incompatibility, G6PD, spherocytosis), Infection (TORCH Screen is indicated)
What are the causes of jaundice of a baby 24 hours- 14 days?
Physiological jaundice, breast milk jaundice, dehydration, infection, haemolysis, bruising, polycythaemia, Crigler-Najjar Syndrome
What are the causes of jaundice of a baby >14 days (>21 if preterm)?
Physiological jaundice, breast milk jaundice, infection (esp UTI), hypothyroidism, G6PD, pyloric stenosis, bile obstruction (biliary atresia), neonatal hepatitis
What causes physiological jaundice?
Marked physiological release of Hb from breakdown of red cells due to high Hb at birth
Red cell life span of newborns is shorter than adults
Hepatic bilirubin metabolism less efficient in first few days of life
