what is the cause of hirschprung disease? where is it most often found? - ✔✔✔
Correct Answer > congenital absence of ganglion cells causing a functional
obstruction- MC in distal colon & rectum (75%)
when is jaundice of the newborn considered nml/physiologic? - ✔✔✔ Correct
Answer > >24 hrs (usually days 3-5 jaundice appears) bc immature liver is unable
to conjugate bilirubin d/t dec UGT enzyme activity- can also occur from
breastfeeding; only physiologic when jaundice is d/t indirect/unconjugated
bilirubin
what are common symptoms following swallowing a foreign body? tx? - ✔✔✔
Correct Answer > sx: dysphagia, odynophagia, drooling, regurgitation, and
chest/abdominal pain
tx: if object is smooth monitor/wait to pass; if object is causing symptoms, is
large, asymmetrical, contains a sharp end, or corrosive like button batteries
then it needs to be removed surgically/endoscopically
encopresis is defined as occuring monthly x 3 mos and 90% of the time is
secondary to _____________ - ✔✔✔ Correct Answer > constipation
(encopresis is accidental defecation)
,what are some pathologic causes of jaundice w/ inc levels of
indirect/unconjugated bilirubin vs direct/conjugated bilirubin? - ✔✔✔ Correct
Answer > -indirect/unconjugated: Crigler-Najjar, Gilberts, Cretinism, &
hemolytic anemia
-direct/conjugated: Dubin-Johnson syndrome, Rotor syndrome, infections
what is the treatment for von Willebrand disease (which presents as inc
bruising/epistaxis, menorrhagia, prolonged bleeding time, and reduced vWf)? -
✔✔✔ Correct Answer > *desmopressin* (releases stores of vWf)
cystic fibrosis is an autosomal _________ disorder of defective CF transmembrane
receptor (CFTR) protein that prevents _________ transport resulting in a buildup

population? - ✔✔✔ Correct Answer > -autosomal recessive
-chloride
-lungs, pancreas, liver, intestines, reproductive tracts
-inc incidence in caucausians
if bacterial conjunctivitis is found to be chlamydia or gonorrhea what is the tx? -
✔✔✔ Correct Answer > admit for IV and topical abx (ophtho emergency)
-gonoccoccal: IV ceftriaxone + topical
-chlamydia: IV azithromycin
neonatal conjunctivitis is aka? if left untreated can develop what? - ✔✔✔ Correct
Answer > ophthalmia neonatorum; corneal ulceration, opacification/scarring,
visual impairment/blindness
,standard prophylaxis given immediately after birth to prevent ophthalmia
neonatorum (neonatal conjunctivitis) includes: - ✔✔✔ Correct Answer >
erythromycin ointment, tetracycline ointment, silver nitrate, or povidone-iodine
if ophthalmia neonatorum (neonatal conjunctivitis) develops on day 1 after birth
what is the most likely cause? day 2-5? day 5-7? day 7-11? - ✔✔✔ Correct
Answer > day 1: silver nitrate (chemical cause- prophylaxis is what can cause the
condition)
day 2-5: gonococcal
day 5-7: chlamydia
day 7-11: HSV
orbital (septal) cellulitis is usually secondary to _________ infection in most
commonly what age group? - ✔✔✔ Correct Answer > sinus; 7-12y; other causes
include dental/facial infxns or bacteremia
what is the most common sinus infection (90%) that causes secondary orbital
cellulitis? what organisms are the cause? - ✔✔✔ Correct Answer > ethmoid; S.
aureus, Strep. pneumo, GABHS (Strep. pyogenes), H. influenzae
work up/Dx? decreased vision, pain w/ ocular movement, proptosis (bulging eye),
eyelid erythema and edema; tx? - ✔✔✔ Correct Answer > dx: orbital cellulitis
work up: CT scan (showing infxn of fat & ocular muscles) or MRI
tx: IV antibiotics (Vanc, Clinda, Cefotaxime, Ampicillin/Sulbactam)
what is the difference b/t orbital (septal) cellulitis and preseptal cellulitis? - ✔✔✔
Correct Answer > preseptal may still have ocular pain, redness and swelling but
NO visual changes or pain w/ ocular mvmt (hasn't affected the muscles)
, misalignment of the eyes is aka? when does stable ocular alignment present in
infants? - ✔✔✔ Correct Answer > strabismus; 2-3 mos
convergent strabismus is aka? divergent strabismus is aka? - ✔✔✔ Correct
Answer > convergent: esotropia (deviated inward "cross eyed")
divergent: exotropia (deviated ouward)
a + Hirschberg corneal light reflex test, diplopia, scotomas (blind spots), or
amblyopia (lazy eye) are clinical manifestations of what condition? what other
tests can be performed? - ✔✔✔ Correct Answer > strabismus; cover-uncover
test to determine the angle of strabismus, cover test, convergence testing
how can strabismus be treated? - ✔✔✔ Correct Answer > -patch therapy: normal
eye is covered to stimulate and strengthen the affected eye
-eyeglasses
-corrective therapy: if severe or unresponsive to conservative therapy
if not treated before 2 y/o, amblyopia may occur and cause decreased visual
acuity that is not correctable
Dx? 1-2 days of ear pain, pruritis in the ear canal, auricular discharge,
pressure/fullness, hearing usually preserved, pain with tug test and tragus
pressure, auditory canal erythema/edema/debris, recent swimming pool use; MC
organisms? Tx? - ✔✔✔ Correct Answer > Dx: otitis externa
MC organisms: *pseudomonas*, proteus, s. aureus, s. epidermis, GABHS,
anaerobes (peptostreptococcus), aspergillus
