In what races is Kawasaki disease more common?
What are the diagnostic criteria for Kawasaki disease
≥5 day fever + at least 4 of the following:
1. bilateral non-exudative conjunctivitis
2. Cervical lymphadenopathy
3. Polymorphous rash
4. Mucositis - strawberry tongue
5. Red and oedematous palms and soles w peeling of fingers and toes
What is an important complication of Kawasaki diseasE?
aneurysm of the coronary arteries - can be fatal!!
What are the Ix for Kawasaki diseasE?
1. increased WCC - neutrophils
2. Increased platelets in 2nd week
3. increased ESR/CRP
4. serial echos for aneurysm or angiography to be accurate
What is the treatment of Kawasaki disease?
IVIG - single dose within first 10 days
Aspirin to decrease risk of thrombosis
If non-responsive to initial dose - prednisolone
Why is aspirin usually contraindicated in children?
due to the risk of Reye's syndrome
What is the cause of rheumatic fever?
In susceptible individuals, there is an abnormal immune response to a preceding infection with group A beta-haemolytic strep
What age does rheumatic fever mainly affect?
What is the major concern of rheumatic fever?
can cause permanent damage to the heart valves
Where is rheumatic fever common?
in developing countries

2. pancarditis - 1 of: CCF, cardiomegaly, friction rub, +ve echo
3. Sydenham chorea - involuntary movements and emotional lability for 3-6m, 2-6m after the inf.
4. erythema marginatum - rash on trunk + limbs
5. subcut nodules
What are the minor manifestations of rheumatic fever?
2. arthralgia (pain but not swelling)
3. Hx of rheumatic fever/HD
4. Raised ECR (>20mm), CRP, WCC
5. ECG - PR interval >0.2S
What must be fulfilled in the criteria for a diagnosis of rheumatic fever?
1 major and 2 minor
PLUS evidence of preceding group A strep infection (scarlet fever, throat swab or serum titre)
What is the management of an acute episode of rheumatic fever?
1. bed rest, limited exercise
3. prednisolone for fever and inflammation
4. Pericardiocentesis for pericardial effusions
4. diuretics and ACEi for symptomatic HF
What is the appropriate management for preventing recurrence of rheumatic fever
What is the most common long term consequence of chronic rheumatic heart disease?
mitral stenosis from scarring and fibrosis of the valve tissue
What is chronic rheumatic heart disease?E
Refers to long term cardiac damage caused by a single severe episode or multiple recurrent episodes of
What is eisenmenger syndrome?

original murmur may disappear
right ventricular failure
What is the management of Eisenmenger syndrome?
What is the most common cause of infective endocarditis?>
alpha-haemolytic strep - strep viridans
What CHD puts children at risk of infective endocarditis?
VSDs, COA, PAD, prosthetics
i.e. when there is a turbulent jet of blood
What sx should raise suspicion of infective endocarditis?
What are the signs of infective endocarditis?
what are ix for infective endocarditis?
What is the treatment of infective endocarditis?
6 weeks IV therapy of high dose penicillin w amino glycoside
IV benzylpenicillin 25mg/kg/4hr
