Pediatric potpourri

3-week-old boy brought to ED with c/o emesis since first week of life

Formula changed twice with no improvement

Effortless spitting up after each feed

Birthweight 7 lbs 2 oz, now 8 lbs

What s appropriate rate of weight gain for babes
What’s appropriate rateof weight gain for babes?

Regain BW by 10 days

then 20-30 g per day 1st 3 months

Double BW by 5 months of age

15-20 g /day 3-6 months

10-15 g/day 6-9 months

10 g/day 9-12 months

Gastroesophageal reflux prevalence
Gastroesophageal refluxPrevalence?

> 40% of infants regurgitate >once/day

  • 50% resolve by 6 months, 75% by 12 months, 95% by 18 months

    Nelson et al, Arch Pediatr Adolesc Med, 2000

    Orenstein, Pediatr Rev, 1999

Gastroesophageal reflux
Gastroesophageal reflux

Not a disease in most cases…

simply reflects immature LES tone

only ~ 1 in 300 infants has “significant” reflux with associated complications

Nelson’s Pediatrics 2000

Name 5 complications of infant ge reflux
Name 5 complications of infant GE reflux:

1. Parental anxiety

  • the biggie

    2. Esophagitis

    (arching, irritability, Sandifer)

  • Failure to thrive

  • Apnea/choking (ALTE)

    5. Recurrent aspiration

  • Ge reflux diagnosis
    GE reflux: diagnosis


    Confirmation of more severe reflux:

    24 hour pH probe

    Milk scan

    UGI barium not sens/specific

    Ge reflux treatment options
    GE reflux: treatment options

    * Consultation with peds or GI

    Pediatric potpourri

    Teary, very stressed 23-year-old first time mom with 3-day-old breast-fed little girl

    • ++ worried that baby “not getting enough”

    • seems hungry, spends 40 minutes nursing but is “on and off repeatedly, cries a lot

    • “my breasts are REALLY SORE, and I’m not sure I even have enough milk for her….”

    • “I called HealthLink to see if I could give her formula and the nurse gave me a 10 minute lecture about the importance of breast-feeding.”

    Baby s exam
    Baby’s exam:

    No dysmorphism; moderate jaundice

    Alert, rouses easily, strong cry

    AF normal, roots, v. strong suck, oropharynx/palate normal

    Normal RR bilat

    Chest clear, CVS normal, good pulses; sl. mottled extremities

    Abdomen/umbilicus normal

    Normal female genitalia and anus

    Spine/hips normal

    Normal Moro, grasp, tone, reflexes

    Ed s rules of infant nutrition
    Ed’s rules of infant nutrition

    1. “Breast is best”…..

    …but ultimately the kid simply needs enough to eat!!!

    2. Lactation consultants are your friends

    Signs of inadequate intake in bf infant neifert clin perinatol 1999
    Signs of inadequate intake in BF infantNeifert, Clin Perinatol 1999

    • Irregular or non-sustained sucking at breast

    • < 1 wet diaper per feed

    • Nursing < 10 minutes/breast each feed; also, shouldn’t be > 25 minutes/breast

    • Failure to demand to nurse at least 8 times daily

    • Taking only 1 breast at each feeding

    • Crying, fussing, and appearing hungry after most feedings

    • Too much weight loss in first week, suboptimal gain thereafter

    Bf strategies
    BF strategies

    • Nipple care

      • Exposure to air, keep dry b/w feeds, apply lanolin, manual milk expression, more freq shorter feeds, nipple shields

    • Proper technique

      • Feed when hungry

      • Ensure proper latch – watch babe feed in ED

      • Most babies are not “avid suckers” in the first three days; by day 4 they “wake up” and start packing on the weight they’ve lost

    • Supplemental bottle feeds with manually expressed milk or formula if necessary

      • “nipple confusion” is overblown!!

    Bf strategies1
    BF strategies

    • Before assuming mom has insufficient milk, exclude 3 possibilites:

      • Errors in feeding technique

      • Remediable maternal factors: diet, lack of rest, or emotional distress

      • Physical disturbances in the baby that interfere with eating or weight gain

    Pediatric potpourri

    • 4-week-old babe presents with very anxious parents – he’s been crying incessantly for several hours, completely inconsolable; several other episodes over past few days, seems to be getting worse. Otherwise feeding well, 6 wet diapers/day, stooling well, no fever. Previously well.

    • Approach?

    How much crying is normal
    How much crying is normal?

    At 2 weeks: 2 hours per day

    Increases to 3 hours at 6 weeks, then declines to ~ 1 hour at 12 weeks

    Infantile colic
    Infantile colic

    • Excessive crying or fussiness

    • Occurs in 10-20% of infants

      Defined as paroxysms of crying in an otherwise healthy infant for > 3 hours/day on > 3 days/week, usually begins ~ 3 weeks of age and resolves at around 3 months of age

    If things haven’t settled by 4 months, consider alternate dx


    • Intense crying for several hours, usually in late afternoon or evening

    • Often infant appears to be in pain, may have legs drawn up, may have slight abdominal distension

    • May have temporary relief with passage of gas


      • early discontinuation of BF

      • Multiple formula changes

      • Parental anxiety and distress

      • Increased incidence of child abuse

    Colic etiology
    Colic: etiology?


    ? Temperament

    ? Ineffective parental response to crying

    ? Overfeeding

    ? Hunger

    Colic diff dx
    Colic: diff dx?

    Rule out:

    • Hair tourniquet

    • Corneal abrasion

    • Incarcerated hernia

    • Consider abuse (shaken baby)

    • Other (ie reflux esophagitis, UTI, inguinal hernia, testicular torsion, intussusception, etc)

    Hair tourniquet
    Hair tourniquet


    • Excision

    • “Nair”

    Colic management

    Reasonably effective:

    Counseling/ reassurance

    Respite care

    Feeding/holding/rocking/sleeping/diaper change

    Routine burping, avoid over/underfeeding

    F/U with GP or peds to provide support and ensure no organic etiology

    Rarely effective:

    Formula changes

    Simethicone to decrease intestinal gas

    Music, car rides, swings etc

    ? Phenobarb or benadryl for occasional relief

    Colic: management

    Pediatric potpourri

    • 10 day old female with foul-smelling discharge from umbilicus

    • Afebrile, feeding/voiding/pooping well, no red flags on history

      Just a smelly belly button or something more?


    • Purulent, foul-smelling discharge with erythema of surrounding skin

    • Secondary to poor cord hygiene

    • S. aureus/Group A Strep/Gm –’s

    • Tx; topical care and systemic antibiotics (

    Omphalitis complications
    Omphalitis: complications

    • Necrotizing fasciitis

    • Sepsis

    • Portal vein thrombosis

    • Hepatic abscesses

    When should the umbilical cord separate
    When should the umbilical cord separate?

    • Usually w/i 2 weeks

    • Delayed separation: think of possible leukocyte adhesion defect

    Pediatric potpourri

    3 day old babe:

    • Red eye with discharge

    • Differential diagnosis?

      • Chemical irritation (esp AgNO3)

      • Nasolacrimal duct obstruction w/ dacryocystitis

      • Gonorrhea

      • Chlamydia

      • Herpes simplex

      • Infantile glaucoma

        Diagnosis: gram stain, culture, flourescein, antigen detection

    Congenital nasolacrimal duct obstruction
    Congenital nasolacrimal duct obstruction

    5% of all newborns

    *absence of conjunctival injection!

    Warm compresses, gentle massage, watchful waiting

    95% resolve by 6 months; if not, refer for probing (earlier if multiple episodes of dacryocystitis)


    Bacterial infection of nasolacrimal gland with duct obstruction


    • Swab C+S

    • Topical + systemic antibiotics

    Gonorrheal conjunctivitis
    Gonorrheal conjunctivitis

    Hyperpurulent discharge at day 2-4

    • Potentially a disaster!!

    • Mgt?

      • Need FSW

      • Admit for antibiotics, eye irrigation, mgt of complications: corneal ulceration, scarring, synechiae formation

      • Rx concomitantly for Chlamydia

      • Rx mom and her partner

    Chlamydial conjunctivitis
    Chlamydial conjunctivitis

    C. trachomatis : presents on day 3-10

    (but may be up to 6 weeks)

    Mom with active untreated chlamydia: babe has 40% chance of infection

    What’s the real worry here?

    • 10-20% have associated pneumonia – untreated can lead to chronic cough and pulmonary impairment

    • “well” with pneumonia and staccato cough

    • Creps/wheezes; patchy infiltrates w/ hyperinflation

    • CBC: eosinophilia

    • Rx: systemic erythro x 14 days

    • Treat mom and her partner,

    Herpetic conjunctivitis
    Herpetic conjunctivitis

    • Day 2-16

    • Flourescein stain: dendritic ulcer

    • Do FSW


    • IV acyclovir, topical vidarabine

    • 30-50% of cases recur w/i 2 years

    Infantile glaucoma
    Infantile glaucoma

    Classic triad (seen in 30%):

    • Epiphora

    • Photophobia

    • Blepharospasm

  • Injected red watery eye

  • Cloudy, enlarged cornea

  • Cupped optic disk

  • Buphthalmos if dx delayed

    Emergent referral to opthalmologist

    Now R otalgia, increased fever, irritable ++

    Acute otitis media
    Acute otitis media

    • accounts for 30% of all pediatric outpatient antimicrobial prescripitions

    • Diagnostic accuracy?

      • We suck

      • Pediatricians only ~ 50% correct

        • Pichichero et al 2001: study of 514 pediatricians

    Pediatric potpourri

    3 year old girl

    Treated for AOM x 3/7 with cephalexin; abx changed to azithro day 4 because of L facial swelling GP attributed to “drug allergy”

    Now day 6, presents to ED with ongoing L “facial swelling”

    Pediatric potpourri

    8 year old boy melting candles on stove

    • Pot on fire: grabs pot, flames his face and hair, pulls hot burning wax over his hands, legs; standing in pool of hot wax before running from room

    • Exam: Alert, GCS 15, not hoarse; has circumoral 1st and 2nd degree burn; 15% BSA 2nd degree burns to rest of body


    Fluid management
    Fluid management

    • Note that the Parkland formula is modified for kids < 20 kg: accounts for proportionately higher maintenance fluid req in smaller children = 3 mL/kg/% burn (1/2 in 1st 8 hours) PLUS maint fluids

    • Know the rule of thumb for maint fluids in kids: 4-2-1

      • 4 ml/kg 1st 10 kg

      • 2 ml/kg 2nd 10 kg

      • 1 ml/kg >20 kg

    Example 12 kg kid with 10 bsa burn
    Example: 12 kg kid with 10% BSA burn

    Conventional Parkland formula:

    • 4 x 12 x 10 = 480 mL

    • ½ in 1st 8 hours = 30 mL/h

      Modified formula:

    • 3 x 12 x 10 = 360 mL

    • ½ in 1st 8 hours = 23 mL/h

    • Add maint fluid: 44 mL/h

    • TOTAL fluids = 67 mL/h

    Functional constipation:“Re-train the bowel”

    Often not aggressive enough

    • Enemas

      • adult fleets OK after age 2

      • May need multiple over 2 or 3 days

      • In severe cases, Go-Lytely ‘til clear

    • Toilet training strategies

    • Diet: fiber/fluids

    When is the first stool normally passed
    When is the first stool normally passed?

    99% of infants pass 1st stool w/i 1st 24 hours

    • Failure = possible obstruction/anatomic/physiologic abnormality
