Q

Umbilical hernia management

A

no need to do surgery until school age (4-6 yrs)

if incarcerated, reduce and then repair soon

if strangulated, reduce in OR and then repair

It is recommended to repair any umbilical hernias with the defect of 1.5 cm or more in children over the age of 2 years because of minimal chance of spontaneous closure

Q

Omphalocele vs gastroschisis

A

Omphalocele
- awful
- sac around the abdominal contents because contents herniate into base of the cord
- often has associated anomalies (ex Beckwith Wiedeman, T13, T18, T21)
- bad baby, good gut

Gastroschisis
- typically smaller defect
- no membrane over the organs
- often isolated
- good baby, bad gut

Q

2 year old girl with painless bright red blood per rectum. What test will best reveal diagnosis?

A

Meckel’s scan

Accounts for 50% of all lower GI bleeds in children younger than 2 yr of age
Painless rectal bleeding (peptic ulceration due to ectopic gastric tissue) Most are asymptomatic.

May cause perforation or peritonitis (like appendicitis). May be lead point for intussusception

Q

Management G tube granulation tissue (CPS)

A

Ensure tube is secured to skin
Remove dressing

Apply warm saline compresses 3–4 times daily

If saline compresses are not effective and tissue is large, moist and friable, consider applying silver nitrate every 2–3 days until it resolves. Protect surrounding skin with a barrier cream before applying silver nitrate to avoid burning normal skin (1,15)
For balloon devices, ensure balloon is intact and appropriately inflated

25
Child with photophobia, squinting and tearing. Rt pupil bigger than left. Watery discharge and conjunctival injection of Rt eye. They are afebrile. Normal pupillary response and EOM but cornea is cloudy. What is the most likely diagnosis:
Glaucoma pupil bigger cornea opaque blepharospasm (squinting)
26
Adenovirus ketatoconjunctivitis
pseudomembranse foreign body sensation looks like viral conjunctivitis No specific medical therapy is available to decrease the symptoms or shorten the course of the disease. Emphasis must be placed on prevention of spread of the disease.
27
Optic neuritis presentation
Unilateral or bilateral visual loss over hours to days Bilateral ON is more common in younger children and is often associated with a preceding viral infection Unilateral ON can also be followed in time by bilateral involvement Abnormal colour vision, visual field loss, sometimes RAPD
28
Risk factors for glaucoma
previous cataract surgery (lens surgery can cause blockage of fluid causing increased IOP)
29
when to refer AOM for ear tubes
- persistent bilateral OME with hearing loss x 3 mo - recurrent AOM with middle ear effusion others: - at risk children - complications of AOM - OME > 3 mo with other problems (behaviour, school, vestibular)
30
Problem for contact lens wearers
Bacterial keratitis
31
most common cause of hearing loss
genetic
32
most common acquired/congenital hearing loss
CMV
33
hearing loss (SNHL), white forelock, heterochromic eyes
waardenburg syndrome - autosomal dominant - hirsprungs
34
who should have hearing screening
everyone - universal hearing screening
35
hearing screen techniques
otoacoustic emmission (level 1, misses hearing loss between 20-30dB) automated auditory brainstem response (AABR) (level 2, do this if at risk for hearing loss. ex CMV, VLBW)
36
rhinitis treatment
first line management is nasal steroids (best treatment) ex. fluticasone can also avoid allergens and try antihistamines
37
AOM CPS statement pearls
No watch and wait approach if: - perforated - temp >/= 39 - <6mo - systemically unwell - symptoms >48hr 6mo - 2yr high dose x 10 days >2 yr x 5 days if perforated, drops + 10 days oral
38
indications for tympanostomy tubes
severe pain complicated AOM (ex. mastoiditis) failed 2 courses abx for AOM unilateral OME x 3 months hearing imairment recurrent AOM 3 in 6 mo or 4 in 12 mo)
39
tube ottorhea
topical abx drops + steroid drops if chronic > 6 weeks, culture and treat accordingly
40
mastoiditis
clinical diagnosis recommend CT temporal bone with contrast to confirm CT with contrast to look for intracranial complication s IV antibiotics CTX +/- vanco myringotomy need hearing screen after treatment CN complications 6 (lateral rectus) and 7 (facial nerve)
41
sinusitis
> 10 days persistent nasal draininage plus either severe symptoms, purulent discharge x 3 days, or worsening symptoms such as fever sinus aspirate not practical imaging not helpful abx: - amoxil 45mg/kg/d - 2nd: amox-clav 7 - 10 days
42
tonsillectomy indications for recurrent strep
>7 episodes in 1 yr >5 episodes/yr x 2 yr >3 episodes/yr x 3 yr
43
order of sinus development
ethmoid and maxillary present at birth ethmoid pneumatized at birth maxillary at 4yo sphenoid by 5yo frontal 7-8yo
44
RPA pearls
typically age 3-4 won't look up, pain, drooling lateral neck xr: widened pre-vertebral space (more than ½ at C2 or full vertebrae at C6/7) IV abx
45
bacterial tracheitis pearls
will describe it as toxic appearing croup, not improving with epi neb, may have cough usually young age <6yr XR: candle dripping, narrow trachea clinical dx IV antibiotics, intubate
46
epiglottitis
2-12 yr,unimmunized classically h flu rapid onset, toxic, sniffing position (head extended, looking up), drooling, no cough/no resp sx XR thumb print sign IV abx, intubate
47
PTA
teenager sore throat, hot potato voice, trismus (wont open mouth), deviated uvula, head may be tilted no XR findings. clinical dx drainage, abx
48
congenital neck cyst
thyroglossal: midline, moves with tongue Branchial: border SCM, most common, non-tender and mobile Ultrasound abx if infected
49
dental caries bacteria
strep mutans
50
first dentist appt
within 6 mo of erruption of first tooth and no later than one year of age
51
conjunctivitis viral vs bacterial
purulent - bacterial - polysporin eye drops watery/mucoid - viral *if contact lens wearer, think pseudomonas
52
neonatal conjunctivitis
first day - chemical first week - gonorrohea *if mom + for gonorrhea, swab baby even if asx and give 1 dose IV/IM ctx until culture back *no longer routine use of erythromycin prophylaxis *IV abx + topical erythro 3 weeks - chlamydia *only swab if symptomatic *if positive, po erythro x 2 weeks
53
blurry vision/pain with foreign body sensation in contact lens wearer
bacterial keratitis infection of the cornea optho consult urgent bactericidal abx for pseudomonas coverage (ex. tobramycin)
54
pseudomembranes
adenoviral keratoconjunctivitis self limited but very contagious
55
dendritic lesions with fluorescein stain
HSV keratitis po or topical antivirals dont use topical steroids
56
uveitis management
if anterior (red eye, iris adhesions, irregular pupil, decreased vision) - can tx with topical steroids if posterior (no signs of erythema, just decreased vision) - systemic steroids
57
eye finding in MS
optic neuritis uni or bilateral vision loss over hours to days
58
amblyopia
functional reduction in vision due to abnormal vision development early in life can be due to strabusmus, refractive error, or deprivation
