Paeds A conditions Flashcards
What are innocent murmurs?
Flow murmurs caused by fast blood flow through various areas of heart during systole
What are the features of innocent murmurs?
Soft Short Systolic Symptomless Situation dependent (infection, anaemia, exercise)
What are the features of a pathalogical murmur?
Murmur louder than 2/6
Diastolic Murmurs
Louder on standing
What investigations should be done if a heart murmur is heard in a child?
ECG
CXR
Echo
What are pan-systolic murmurs?
Murmurs that start at s1 and extend up to s2
Sign of Mitral Regurg if heard at 5th ICS mid clavicular line
Tricuspid regurg if heard at tricuspid area
VSD if heard at Left lower sternal border
What conditions are associated with ejection systolic murmur?
Aortic stenosis at aortic area
Pulmonary stenosis
HOCM (fourth intercostal space, left sternal border)
What is heard during auscultation of an atrial septal defect?
Mid-systolic, crescendo-decrescendo murmur loudest at upper left sternal border, with a fixed splitting heart sound.
What is heard in patent ductus arteriosus?
Small patent ductus arteriosus may not cause abnormal heart sounds
Larger ones cause a continuous crescendo-decrescendo machinery murmur that may continue during a second heart sound
What is heard in tetralogy of fallot?
Arises from pulmonary stenosis so ejection murmur at the pulmonary area is heard
What is cyanotic heart disease?
When deoxygenated blood enters the systemic circulation as it bypasses the pulmonary circulation and the lungs.
Occurs due to a right-to-left shunt
What conditions cause cyanotic heart disease ?
VSD
ASD
PDA
Transposition of the great arteries
What is Eisenmenger syndrome ?
When blood flows from the right side of the heart to the left across a structural heart lesion.
What three conditions result in Eisnmenger syndrome?
ASD
VSD
Patent Ductus Arteriosus
What is coeliac disease?
An autoimmune condition where exposure to gluten causes an immune reaction which creates inflammation in small intestines
What autoantibodies are involved in coeliacs?
anti-TTG
antiEMA
Where does the inflammation in coeliacs disease occur?
The jejunum
- causes atrophy of the intestinal villi (malabsorption of nutrients and disease related symptoms)
How does coeliac disease present?
can be asymptomatic if not: - failure to thrive - Diarrhoea - Fatigue - Weight loss - Mouth ulcers - Anaemia second to iron, b12 or folate deficiency - dermatitis herpetiformis
What genes are associated with coeliac?
HLA-DQ2 gene (90%)
HLA-DQ8 gene
How is coeliac diagnosed?
investigations should be carried out whilst patient remains on a diet containing gluten
Total IgA levels
Specific antibodies - anti TTG and anti-EMA
