9
Q
What is physiologic jaundice?
In what time frame do you see babies?
A
It is jaundice seen AFTER the first 24 hours (if seen with first 24 h = pathologic jaundice)
- Its is due to a lot of things:
- Breast feeding - dehydration and lack of milk
- Incr Hct and shorter rbc life span (80-90days)
- Impaired hepatic clearance (patent ductus venosus)
- Enzyme def of UPD glucuronyl-transferase (coverts bili to direct bili to be excreted)
-
10
Q
Peds: In breast milk jaundice - what enzyme is increased? (this is the reason why they are jaundiced
A
There is an increase in beta-glucuronidase (this converts bili diglucuronide to bili which is then recirculated
- UDP glucuronyl transferase - converts bili to direct bili which is then excreted in stool

OVER PRODUCTION

- Polycythemia
INCREASED REABSORPTION
- Breast milk jaundice (incr Beta glucuronylase - pervents conversion of bili to direct - is recirculated)
REDUCED EXCRETION
Hepatic delivery/uptake:
- patent ductus venosus ‘shunt bilirubin from liver conjugation’
- Blockage of cytosol receptor protein (milk, drug)
- Glucuronyl transferase (Gilbert’s, familial)

4. If pH <6.9 some will consider adding NaHCO3
49
In DKA - if urine dip is negative or serum is negative for ketones, is it still possible to have DKA?
Yes. the urine dip only recognises Acetoacetate but not B-hydroxybuterate (the 2nd type of ketone made) so you can run specific test for this.

| 2. Low dose insulin.
51
In DKA, why would you not give insulin right away? (hint K)
If the K is <3.3, then do not give insulin because it will cause hypokalemia and can precipitate an arrhythmia. So replace K first then give insulin.
52
In DKA, what does the literature say about initial Bolus insulin?
1. Studies show that initial bolus (0.1U/kg once) does not confer any benefit and may be assc with cerebral edema - but this may be due to fact that those pts were more severe)
2. We have moved away from Bolus and just give infusion now.
53
In Peds DKA - what is the current thinking in terms of fluid resuscitation.
1. Fluid resuscitation - current literature is saying you don't want to give more than 45cc/kg of fluid (bolus) in first 4 hours - may incr incidence of cerebral edema.
2. Consider talking to pediatric endocrinologist.
Ultimately literature on this is sparse.

| 2. Group A Beta hemolytic Strep
106
Toxin mediated, Kolsy's sign +, desquamation of entire skin in infants and toddlers, dehydration main concern, not mediated by staph or strep. What is the diagnosis?
Staphylococcal scalded Skin Syndrome (SSSS)
107
What are the main complication of Kawasaki's disease?
1. Coronary a. aneurysms
| Can also get: Myocarditis, Valvulitis, Pericardial effusion, systemic artery aneurysms
108
Measles (red measles):
What virus is it caused by?
What is the characteristic history and rash?
What are 4 bad complications?
1. Morbillivirus
2. Prodrome: cough, coryza, conjunctivitis, fever, (may have koplik spots), then abrupt rise in fever then Maculopapular Rash starting on head then spreads to rest of body.
can get lympadenopathy in the 2nd phase which may be assc with intussecption..
May have hemorrhagic disease and mild liver involvement in adults
3. Pneumonia, OM, and encephalitis, subacute sclerosing panencephalitis (fatal), DIC
109
What are the most common causes of pediatric out of hospital cardiac arrest?
1. SIDS- 23%
2. Trauma - 20%
3. Submersion injuries - 12%
110
What are 10 differences of the pediatric airway?
1) Big tongue and more soft tissues (adenoids)
2) Narrowest point at subglottis - Narrowest part of the trachea is at the cricoid versus the vocal cords – Makes tube sizing more critical
3) Anterior/cephalad larynx - Higher and more anterior glottis opening – Makes the oral, pharyngeal and tracheal axis more difficult to align
4) Short trachea - Short trachea (5-6cm) – Can make tube dislodgement with head manipulation and accidental intubation of the right mainstem bronchus easier
5) Large occiput - puts pt in flexion. To get sniffing position= roll under shoulders
6) Big floppy epiglottis- use miller blade
7) Higher metabolic rate
8) Lower FRC - Makes a neonate desaturate faster once they have been paralyzed. Higher metabolic demands – Have a much higher cardiac output and therefore will utilize oxygen much faster
9) More compliant chest wall
10) Smaller airway caliber - need appropriate size of equipment
111
What is Eisenmenger's syndrome?
Process of L to R shunt turning into a R to L shunt.
| - Can occur in congenital VSD, initially left side has higher pressures then there is RVH and the shunt revereses
112
What are 7 side effects of PGE-1? - to keep open PDA (cyanotic heart dz)
In what condition is PGE-1 contraindicated?
1. Apnea (consider intubating)
2. Hypotension
3. Bradycardia
4. Cutaneous vasodilation (Flushing)
5. Seizures
6. Hyperthermia
7. Renal Failure
8. ICH/NEC (necrotizing enterocolitis)
Contraindicated in TAPVR (will make worse)
113
AVSD is associated with what syndrome?
Down's syndrome.
114
What is considered a concerning level of conjugated bilirubin?
if the level is above 10 or 20% of the TSB
115
Where in the esophagus is a FB more likely to get stuck?
1. Thoracic inlet (between clavicles - anatomical change from skeletal m. to sm. m)
- Cricopharyngeus sling at C6 is also at level of inlet. (70%)
2. Mid esophagus (15%)
- aortic arch and carina overlap- there is a natural narrowing.
3. Lower esophageal sphincter (15%)
