Newborn Pearls-Evidence Based
Ann Soenen, D.O.May 16, 2014
Objectives
• Become familiar with the Stanford online photo gallery
• Recognize unique newborn exam findings• Formulate a treatment plan for these issues• Provide valuable instructions to the parents
through use of a post-nursery discharge checklist
Gimme the vitals
• Apgars– Know how to calculate
• Temp– axilla of 36.1 to 37°C (97 to 98.6°F) in an open crib
• HR – 120 to 160
• RR – 40 to 60
• BP – depends on gestational age, weight

Newborn Skin Rashes-Birthmarks
• CONGENITAL MELANOCYTIC NEVI• DERMAL MELANOSIS• HEMANGIOMAS• NEVUS FLAMMEUS• NEVUS SIMPLEX
Newborn Skin Rashes- Common Rashes
• Transient Vascular Phenomenon– CUTIS MARMORATA– HARLEQUIN COLOR CHANGE
• Erythema Toxicum Neonatorum• Transient Neonatal Pustular Melanosis• Acne Neonatorum• Milia• Miliaria (crystallina and rubra)• Seborrheic Dermatitis
Yellow?
• Never normal in 1st 24 hours• Eyeball vs TcB vs TsB?
– Visual assessment not as reliable– TcB not reliable during phototherapy, ?darkly
pigmented skin– TcB can replace TB in most circumstances when TB
is <15 mg/dL• Universal screening or Selective screening?• If intermediate-risk zone -> now what?
Phototherapy
• Plot the curve or online calculator- bilitool.org• NNT
– It is estimated that 5 to 10 infants with TB between 15 and 20 mg/dL must receive phototherapy to prevent one patient from developing a TB >20 mg/dL.
• Decline of TB at least 2 to 3 mg/dL within four to six hours– Result in 30-40% decrease in 24 hours
• Additional evaluation or not?• Home Bili-blankets?
For infants at low risk (≥38 weeks GA and without risk factors), phototherapy is started at the following TB values.24 hours of age: >12 mg/dL 48 hours of age: >15 mg/dL 72 hours of age: >18 mg/dL
Infants in this category who have TB levels 2 to 3 mg/dL below the recommended levels may be treated with fiberoptic or conventional phototherapy at home.
Murmurs
• Innocent or not? • Guess the problem? (Stanford audio file)
Congenital Heart Disease
• Didn’t you hear it? – Often Missed
• CHD O2 screening (Lancet 2012-universal)– Postductal (NOT R arm)– SpO2 <95 %
• Detection rate on prenatal ultrasound– Highly variable– Better if 4-chamber view w/ outflow tracts or
fetal echo
Head
• The Abnormal Fontanel– Large anterior fontanel or delayed closure– Achondroplasia, Hypothyroidism, Down
Syndrome, Rickets, Increased intracranial pressure• Caput vs cephalohematoma
– When will it improve?• Subgaleal protocols• Craniosynostosis
Red Reflex- now I see it now I don’t
• Leukocoria– DDx: retinoblastoma, congenital cataract– How soon to see ophthalmology?
• Darker pigmented skin?
Dacro- what?
• Dacryostenosis– Nasolacrimal duct obstruction, m/c cause of tearing in
infants– Spontaneous resolution by 6 months in 90%– Tx:
• Lacrimal cyst massage• Probing
• Dacrocystocele or dacryocele or NLD cyst– Refer to opthalmology urgently
• Dacrocystitis– Systemic antibiotics
Tongue-Tied
• History of Frenotomy for Ankyloglossia:• Popularity of casual frenotomy in the early 20th century• Procedure fraught with complications: bleeding,
infection, scarring, "regenerating"• Fell into disrepute in the mid 20th century• Concurrent popularity of formula feeding• Older and recent text books claimed frenotomy
unnecessary• Current resurgence of breastfeeding demands revisit of
topic
Frenotomy or Frenulectomy
• Maternal complications- sore nipples• Infant complications- FTT• Pediatric complications- speech, orthodontic,
social• Hazelbaker
Assessment Tool for Lingual Frenulum Function
• No anesthesia if performed under 3-4 months, can do in office
Abdominal masses
• Normal or not?– Diastasis recti
• Umbilical hernia– Management
• Umbilical cord– Single umbilical artery– Care & Normal detachment (in 1 wk)– Umbilical granuloma tx?
Preauricular Skin tags/pits
• Do all need screened for renal anomalies?• Screen for hearing impairment
Extra digits
• Polydactyly vs Syndactyly• Tie off or leave?• Associations?
Newborn Foot
• Metatarsus adductus– m/c, medial deviation forefoot– Most resolve, exercises, rare splinting
• Positional calcaneovalgus feet (talipes calcaneovalgus)– hyperdorsiflexion of the foot with the abduction of the
forefoot– Most resolve, exercises, splinting
• Clubfoot (talipes equinovarus)– Most spontaneous, can be genetic– manipulation that includes casting and bracing (referred to
as the Ponseti method
V-finger Test
Calcaneovalgus
Clubfoot
Sacral dimple
• When do you need an ultrasound?– If visible intact base-> OK– If deep/large > 0.5cm, > 2.5cm from anus, or have
tuft hair/vascular lesion -> Need u/s
DDH-Click or Clunk?
• Algorithm AAP• Exam (until age 2)
– Ortolani and Barlow maneuvers– Galeazzi and Klisic signs
• U/s use• Referral for tx
– Triple diapers not recommended– Pavlik harness
Screening for developmental hip dysplasia—clinical algorithm.

It’s a Boy or Girl?
• Vaginal skin tags, discharge• Hydroceles vs inguinal hernias
– transillumination• Undescended testicle
– 2-5% at term– When to refer?
• Hypospadias, epispadias• Ambiguous
Gomco Circumcision Q’s
• If don’t get circumcised- do they have to retract foreskin and clean?– No, just clean like rest of body
• Potential Benefits• Potential complications• When to call urology?
Discharge InstructionsProperly feeding the infant Instruction on proper breastfeeding position, attachment, and adequacy of swallowing Breastfeeding mothers should consult their physicians before taking any new medications.Parents should not give their infant supplemental water or honey. Breastfed and bottle-fed infants receiving less than 500 mL of formula per day should receive 200 IU of a vitamin D supplement per day. Urination patterns Six or more wet diapers per day is normal for a breastfed infant after the mother’s milk has come in, as well as for bottle-fed infants. Bowel movements More than three bowel movements per day is normal in breastfed infants.Bottle-fed infants may have fewer bowel movements. Umbilical cord care Instruction on proper cleaning Skin care Review of common rashesGenital care Instruction on proper care of circumcised or uncircumcised penises, as well as care of newborn girls’ genitals Signs of illness Rectal temperature of 100.5˚F (38˚C) or higher Signs of dehydration, lethargy, poor feeding Prevention of sudden infant death syndromeInstruction on properly positioning the infant for sleep
