Paediatrics Flashcards
What is hypoxia ischaemic encephalopathy?
Compression of umbilical cord during birth causing brain damage due to lack of oxygenation.
Results in seizures, hypotonia, poor feeding.
What is the ratio of neonatal compressions in resuscitation? When do you begin them?
3:1 once HR drops below 60bpm
What is a Potter Sequence?
Flattened nose, recessed chin, low-set ears, and the presence of respiratory distress due to pulmonary hypoplasia. Also associated with renal a genesis (failure to develop).
Results from oligohydramnios (lack of amniotic fluid) in utero.
What are the consequences of congenital toxoplasmosis?
Hydrocephalus, chorioretinitis, intracranial calcifications (USS)
What is the Pierre-Robin Sequence?
Cleft palate, retracted tongue (glossoptosis), small lower jaw (micrognathia).
It tends to resolve on its own within 3-6 months but if not may require surgery.
What signs do you get with a PDA due to turbulent blood flow?
collapsing pulse and murmur at the left sternal border
What is osteogenesis imperfecta?
Collagen type synthesis defect causing easy breaking of bones, blue sclera, dental abnormalities, virus deformity, and possibly hearing defects as they age.
What is Ebstein’s abnormality?
Lithium during pregnancy causes baby to have a tricuspid valve defect (septal and posterior leaflets are downwardly displaced in RV) causing blood to leak back into RA, causing an enlarged RA and congestive heart failure due to insufficient blood flow.
What is Acute Bilirubin Encephalopathy (ABE)?
Sustained/prolonged elevated levels of bilirubin in neonates can cross the blood brain barrier and penetrate the neuronal and glial membranes (as it is lipid soluble) causing lethargy and hypotonia.
What is Meckel’s Diverticulum? How does it present? How is it diagnosed?
Congenital abnormality where thee is a remnant of the embryonic Vitelli-intestinal duct. Painless rectal bleeding, non-specific abdominal pain, intestinal obstruction/intussusception.
Technetium 99 scan will show an increased uptake in the ectopic tissue.
What is tuberous sclerosis?
TSC1 or 2 gene mutation causes growth of benign tumours in different areas of the body.
What are the manifestations of tuberous sclerosis?
Skin: ash-leaf macules, shagreen patches, facial angiofibromas, subungual fibromas
Neuro: infantile spams with hypsarrhythmia on EEG (interictal high amplitude waves on a background of irregular spikes), learning disabilities, subependymal cysts.
Renal: angiolipomas
Cardio: cardiac rhabdomyomas
What is a Capet succadeneum?
Fluid filled lump on head due to fluid crossing suture lines during birth due to pressure.
Usually self resolving.
What are the consequences of foetal alcohol syndrome?
Microcephaly, short palpebral fissures, hypoplastic upper lip and absent philtrum, decreased IQ, cardiac abnormalities.
What are the signs of NEC? How is it managed?
Bilious vomiting, blood stained stools, pneumatosis intestinalis (gas cysts in the bowel wall), bowel wall oedema, dilated bowel, pneumoperitoneum (if perforated).
Broad spec Abx and tpn instead of milk to rest the bowel.
A long lasting cough causing vomiting and cyanosis should make you suspicious of what?
Bordetella pertusis (gram -ve cocobacilli): whooping cough
What causes Roseola infantum? How does it present? How should it be managed?
HHV 6/7.
High temperature followed by rose pink macular rash as the fever goes down.
Manage conservatively.
What virus causes croup? How does it usually present?
Parainfluenza.
Barking (seal-like) cough, inspiratory stridor, and respiratory distress usually affecting 6 month olds to 2 year olds.
What do you see on CXR of Croup? Mx?
Steeple sign due to oedema of the larynx resulting in supraglottic narrowing.
Mx: Steroids - dex.
How does ITP present in children?
Non-blanching, non-palpable rash that appears shortly after infection in the absence of other features.
Platelets are significantly decreased
How is ITP managed in children?
Supportively - self limiting condition in children
What must you rule out in children presenting with ITP?
Leukaemia - repeat bloods 1 week after presentation to rule this out
What is HSP? How does it present?
Henoch-Scholein purpura: IgA vasculitis.
Often in 3-15 y/o following URTI. You get a non-thrombocytopenic purpura, arthralgia, haematuria, and non-specific abdo pain.
How do we manage HSP?
Mainly supportive (aka analgesia) however corticosteroids may be used.
Regular urine dips up to 1 year after diagnosis to monitor for haematuria and proteinuria.
How does transient synovitis present? How is it managed?
Inflammation of the hip causing pain, following URTI. Most commonly in 3-10 y/o males.
Mx: PRN painkillers. Resolves spontaneously.
Children <6 months presenting with recurrent UTIs should be referred for what?
MCUG (micturating cystourethrogram)
