1
Q
acrocyanotic
define
apgar score
A
blue hands and feet
add 1 to apgar
2
Q
grimaces to stimulation
apgar score
A
add 1 to apgar
not full withdrawal to stim, that would be 2
3
Q
tf
apgar guides therapy and has prognostic value
A
f
just descriptive basically
4

what makes up mongolian spots
A
arrested melanocytes
8
Q
pale pink vascular macules on face or nuchal area
aka
persist or resolve?
A
(nevus simplex) salmon patch
on the face regress
on the neck may persist into adolescence
9
Q
firm white papules on face of newborn on day one aka filled with may confuse with... but won't because..
A
milia
filled with keratin
may confuse with neonatal acne
but won’t because acne presents later (week of life 1 or 2, not day of life 1)
10
Q
firm yellow/white papules/pustules on an erythematous base on day of life 2
aka
filled with
A
erythema toxicum
filled with eosinophils
11
Q
bright red sharply demarcated raised lesion in first few months of life aka
A
hemangioma
12
Q
tactile difference nevus simplex vs hemangioma

nevus simplex (salmon patch) is not palpable
hemangioma is raised, palpable, sharp borders
13
Q
erythematous papules on face in week of life 1 or 2
aka
A
neonatal acne
14
Q
why does neonatal acne occur
A
hormones! same as teens
circulating maternal androgens
15
Q
biggest clue milia vs neonatal acne
A
time of presentation
milia - day 1 of life
neonatal acne - week 1 or 2 of life
16
Q
area of alopecia with orange colored nodular skin
aka
mgmt
A
nevus sebaceous
remove before adolescence because risk of malignant transformation
17
Q
newborn seborrheic dermatitis
aka
describe
manage
A
cradle cap
thick yellow/white oily scale on an inflammatory base
mild shampoo… eg on a soft toothbrush and scrub away… pretty easy to get rid of
18
Q
2 neonatal disorders screened in every state because disastrous if not caught early and contraindicate breast feeding path time to sx sx mgmt
A
- PKU Phenylketonuria
- deficient phenylalanine hydroxylase, phe accumulates in brain
- sx take a few months to arise
- developmental delay, mental retardation, vomiting, athetosis writhing muscle contractions, fair hair eyes skin, musty smell
- low phenylalanine diet
Galactosemia
- deficient G1p-uridyl-transferase, G1p accumulates and damages kidney liver brain
- right at birth (galactose can cross placenta)
- mental retardation, jaundice hyperbilirubinemia, hypoglycemia, cataracts, seizures
- no lactose diet (no breast milk!)
19
Q
tf
phenylalanine and lactose are present in breast milk

T
that’s why important to screen for PKU and Galactosemia in neonates

A
direct
24
Q
does hypothyroidism cause neonatal direct or indirect hyperbilirubinemia
A
direct
25
pathogenesis of dubin johnson and rotors
secretion... absorption... or something... get conjugated hyperbili... not a conjugation defect (that's gilbert and crigler najar unconjugated hyperbili)
26
dubin johnson vs rotor liver color
dubin johnson black liver
rotor red (normal) liver
27
where does indirect bilirubin deposit in the brain in kernicterus
basal ganglia
| cranial nerve nuclei
28
tf
| phototherapy conjugates bilirubin
FALSE
it ionizes the unconjugated bili so that it becomes soluble and can be excreted... but does not conjugate it... whatever that means
29
diaphragmatic hernia identified prenatally
the big worry
how to manage delivery and repair
big worry is pulmonary hypoplasia
ECMO (extracorporeal membrane oxygenation) after delivery to support for a few days and let lungs mature... THEN operate 3-4 days after delivery...
30
drooling newborn who can't breath think...
esophageal atresia
| tracheo-esophageal fistula, etc
31
VACTERL

corticosteroid prenatally to stim lung maturation
O2 therapy with nasal CPAP to keep alveoli open
37
tf
| theophyline for RDS
false
theophylline for problems with respiratory drive (central sleep apnea)
RDS is a problem of oxygenation, not respiration
38

dx
pathophys
tx/prognosis
TTN
transient tachypnea of the newborn
cxr perihilar streaking from retained fluid in lung fissures

minimal O2 needed usually, self resolves in hours-dats
39

(midline defect WITHOUT BOWEL present)
assoc
tx
assoc w Congenital Hypothyroidism
43
newborn
big tongue
umbilical hernia
think...
assoc
tx
congenital hypothyroidism
| vs big tongue and ompalocele... and ear pits, low glucose assoc w Beckwith Wiedemann Syndrome
44
big tongue and umbilical hernia think...
| not..
congenital hypothyroid
| if big tongue and Omphalocele think beckwith wiedemann syndrome... espec if with ear pits, low glucose

maybe formula...
```
48
treat necrotizing enterocolitis
NPO TPN abx resection of necrotic bowel
49
prune belly syndrome
define
association
failure of abdominal musculature to form so belly looks pruny because intestines underneath skin more easily visualized
assoc w cryptorchidism
50
tf
| orchopexy for cryptorchidism decreases risk of cancer
tish fish
| does not decrease rate of cancer... but increases detection of testicular changes so id and tx faster

dx
most common cause
most definitive test

posterior urethral valves
(mass is distended bladder)
cath then surg
53
infant complications of maternal type 1 diabetes
how to prevent
placental insufficiency/IUGR, congenital heart disease, neural tube defects, caudal regression syndrome, small left colon syndrome
control insulin during pregnancy, especially 1st trimester, take 4mg of folate per day
54
infant complications of gestational diabetes (gimme6)
LGA (from fetal hyperinsulinemia), birth trauma clavicle fx BPBP risk, TTN risk because csection rates higher
hypoglycemia (from fetal hyperinsulinemia), neonatal seizures
hypocalcemia, neonatal seizures
polycythemia (big baby needs more O2 delivery so makes more EPO), renal or splenic vein thromboses
jaundice (more RBCs to break down), kernicterus
RDS (hyperinsulinemia interferes with cortisol surge prior to birth that normally stimulates lung maturation)
55
treat neonatal hypoglycemia due to gestational diabetes
feed frequently (eg breast milk) if glucose v40, IV dextrose of glucose v20
