Q

When assessing Moro on LGA newborn r. arm remains extended and medially rotated

A

LGA = large for gestational age

Erb-Duchenne (Erb’s palsy) C5-C6: brachial plexus injury during birth (typically from shoulder dystocia)

-refer if not better by 3-6 mo for surgical repair

=> waiter’s tip deformity

Q

Describe why babies born to mother w/ GDM are at an increased risk for renal or splenic vein thrombosis

A

B/c of increased viscosity of blood, polycythemia = increased RBC percent of blood make up
-b/c large babies need more O2, hypoxia stimulates EPO production

Q

Why do mothers w/ gestational diabetes have larger babies?

A

Mothers w/ gestational DM have increased risk of LGA (large for gestational age)/macrosomia b/c extra blood glucose crosses placental barrier => triggers fetal insulin release
-insulin acts as growth hormone

Q

1 wk old baby w/ bileous vomiting, draws up his legs, has abdominal distention

A

Malrotation and volvulus

  • Malrotation = during development the intestines fail to rotate 270 ccw around the SMA => intestines set into wrong part of the abdomen so they become blocked or twist
  • Volvulus = bowel twists on its own blood supply since it is not properly fixed in place, can be fatal if becomes ischemic

82
Q

1 week old baby becomes cyanotic when feeding but pinks up when crying

Choanal atresia = back of nasal passage (choana) is blocked

  • presents when feeding bc oral air passages are blocked by the tongue

A

Biliary atresia = bile ducts cannot drain bile

=> liver failure => need surgery

87
Q

Differentiate caput succedanem vs. cephalohematoma

A

Edema that crosses suture lines = Caput succedanem

  • extraperiosteal fluid collection due to pressure of scalp against dilating cervix during delivery
  • tx: observation only

Fluctuance that doesnt cross suture lines = cephalohematoma = blood btwn skull and periosteum due to BV rupture
-tx: usually just observation, sometimes image if neurological symptoms appear, don’t aspirate to remove blood (risk of infxn)

Cephalohematoma- swelling is periosteal => boundaries limited by the individual bones

88
Q

Tx for hyperbilirubinemia

A

Phototherapy

-ionizes unconjugated bili so it can be excreted

89
Q

14 day old, bili at 12, dbili .5, baby regaining birth weight and otherwise health

A

Breast milk jaundice- due to glucoronidase and de-conj bili in breast milk

-consider breast milk in jaundice baby that is otherwise healthy

90

Breast feeding jaundice- baby not getting enough breast milk

93

97
Q

2 Ddx for 3 day old who has not passed meconium

A
  • Meconium ileus (thickens and congests in the intestines)- consider CF if have family history
  • Hirschsprung’s (congenital megacolon): absence of nerves in parts of the intestines due to defect in enteric nervous system
98
Q

If detected in utero what can be given to prevent RDS in premies

A

Give antenatal (before birth) betamethasone = steroid to speed up development

99
Q

Diagnostic test for Hirschsprung’s disease

A

Hirschsprung’s = congenital megacolon, part of LI or GI tract has no ganglion cells (=> cannot relax part of the colon to pass stool => obstruction) due to incomplete neural crest cell migration

Gold standard = biopsy revealing no ganglia

100

A

Gestational diabetes if classified by how it’s treated

A1GDM = treated w/ diet alone
A2GDM = treated w/ insulin
101
Q

Describe the pathophysiology of a black liver in Dubin Johnson Syndrome

A

On autopsy the liver of a Dubin Johnson pt will have a black appearance due to pigment accumulation
-hepatocyte defect in secreting conjugated bilirubin into bile

102
Q

Tx for necrotizing enterocolitis

A

NPO, abx and resection of necrotic bowel ASAP

103
Q

Tx for cryptorchidism

A

Cryptorchidism = absence of one or both testes from the scrotum

Tx = watch and wait, most will descend by 3 mo

If not descended by 1 year- surgery to avoid sterility/cancer

104
Q

2 congenital infxns that can cause chorioretinitis

(a) How to distinguish

A

Varicella + Toxoplasmosis- both are congenital infxns that can cause chorioretinitis

(a) Distinguish by the other features
Varicella- limb hypoplasia, cutaneous scars, cataracts, cortical atrophy
Toxo- hydrocephalus, intracranial calcifications

105
Q

4 wk old infant w/ non-bileous vomiting and palpable “olive”

-olive-shaped mass in upper belly = the abnormal pyloris

106
Q

Differentiate gastroschisis vs. omphalocele

(a) location
(b) main distinction
(c) prognosis

A

Look similar, both treated w/ surgery

Gastroschisis is lateral (not midline) and doesn’t have a cover
-not associated w/ other d/o

Omphalocele- defect in midline and is covered by a sac
-associated w/ Edwards (trisomy 18), Patau (Trisomy 14), Beckwith Wiedemann Syndrome => worse prognosis

107
