Pediatric Wellness/Mary Gallagher Lectures Flashcards
Most victims of child abuse are below what age?
85% of victims are < 3 yo
What is the most common fracture of child abuse?
Femur fracture = most common fracture of child abuse
What are some red flags associated with Sexual Abuse in children?
- difficulty walking or sitting
- signs of trauma in external genitalia
- injury or STI that is unusual for age group
- Frequent UTI/yeast infections
- Pregnancy at a young age
What is the primary risk factor for infant head trauma or other forms of physical abuse?
infant crying
At what age does crying peak?
2-4 months
Why do neonates have low levels of vitamin K?
- vitamin K is synthesized by bacteria in gut → absence of gut flora
- inability of the fetal liver to store vitamin K
Why do we apply erythromycin to infants?
- prevents ophthalmia neonatorum from N. gonorrhoeae & C. trachomatis
- Gets applied topically onto the conjunctival sacs immediately after birth
Why do we give Hep B iz in newborns?
- Prevent transmission of Hep B
If birth parent = Hep B surface antigen positive → infant needs hep B Iz AND hep B immune globulin
Exclusive Breastfeeding & Hyperbilirubinemia
- “Breastfeeding Jaundice”
- Related to suboptimal milk intake
- Peaks at 3-5 days of life
- Frequently associated with excess weight loss
- “Breast Milk Jaundice”
- Hyperbilirubinemia that persists with adequate human milk intake and weight gain
- Prolonged unconjugated hyperbilirubinemia
- Can last up to 3 months (Mary said she hasn’t seen it last longer than 6-8 weeks)
- Almost always nonpathologic and not associated with direct or conjugated
Risk factors for significant hyperbilirubinemia
- Lower gestational age
- G6PD deficiency
- Hemolysis from any cause
Hyperbilirubinemia Neurotoxicity Risk Factors
- Gestational age < 38 wk
- Albumin < 3.0 g/dL
- Isoimmune hemolytic disease (i.e. positive direct antiglobulin test), G6PD deficiency, or other hemolytic conditions
- Sepsis
- Significant clinical instability in the previous 24H
Gestational Age Classifications
Term: GA 37+ weeks
- Late Preterm: GA 34- <37 weeks
- Moderate Preterm: GA 32- <34 weeks
- Very Preterm: GA < 32 weeks
- Extremely Preterm: GA = 25weeks
What is prolonged Jaundice and what do you do?
- 3-4 weeks in breastfed infants ; 2 weeks on formula fed infants
- Check NB screen for conditions that can lead to persistent jaundice
- Consider GI consult with any formula fed infant with prolonged jaundice or breastfed infant with direct hyperbilirubinemia
Preterm Infant Birth Weight Classification
Infants are classified by birthweight:
- Low Birth Weight: BW < 2500g
- Very Low Birth Weight: BW < 1500g
- Extremely Low Birth Weight: BW < 1000g
APGAR Scores: When and how to calculate?
*Done at 1 & 5 minutes*
-Preterm infants and emergency c-section babies = more likely to have low scores
Newborn Weight Loss
- Weight loss is NORMAL
- -Weight loss 10% + needs to be investigated
- > 7% in the first few days after birth should be monitored and investigated!
- -should return to birth weight by 2 weeks
- -30 grams = 1 ounce
Feeding
Normal Ins and Outs for newborns
- Feeds: 8-12x/24 hours

Newborn Metabolic Screening
State Specific
in CA → 80 disorders that are genetic or congenital
critical Congenital Heart Disease
- Usually initially identified by low pulse ox levels
- Screening for: hypoplastic L heart syndrome, pulmonary atresia, tetralogy of Fallot, total anomalous pulmonary venous return, transposition of the great arteries, tricuspid atresia, truncus arteriosus
Hearing Screening in Newborns
- **all infants should be screened by 1 mo old**
- Those who fail initial screening → need to be assessed by audiologist by 3 months of age, with intervention by 6 months
-
Automated auditory brainstem response:
- Click or chirp stimuli at 35dB → surface electrodes on forehead, nape, and mastoid or shoulder
- Measures waveforms in response to stimuli and then compares them to normal neonatal templates → pass or fail
-
Otoacoustic Emission:
- Measure the presence or absence of sound waves generated by the cochlear outer hair cells of the inner ear in response to sound stimuli
-
Risk Factors for Hearing Loss:
- NICU for 5+ days
- Hearing loss syndromes
- Family hx of hereditary childhood hearing loss
- Craniofacial anomalies
- Congenital infx
- Severe hyperbilirubinemia → serum bili > 35 mg/dL (599 micro/L) or requiring exchange transfusion on a preterm infant
- Delivery Complications: perinatal asphyxia, cooling, or problems during delivery (e.g. 5 min APGAR score < 6)
- Ototoxic Meds: ampicillin, gentamicin, oxacillin, tobramycin
Newborn Reflexes
-
Crawling Reflex (Baur Crawling): disappears at weeks-months after birth
- place infant on stomach, apply pressure with hand onto bottom of foot → baby will try to “crawl”
-
Step Reflex: disappears at 3-4 mo
- infant will try to take steps when held upright with slight weight on feet
-
Tonic Neck Reflex (Fencing): disappears at 4 mo
- infant on back with head turned to right → R arm will extend, L arm will bend.
- reverse if head turned to L → L arm will extend, R arm will bend
- infant on back with head turned to right → R arm will extend, L arm will bend.
-
Rooting Reflex: disappears at 4 months
- touch corner of infant’s mouth
- Sucking Reflex: disappears at 4 mo
- Palmar grasp: disappears at 4-6 months
-
Moro Reflex (Startle): disappears at 6 months
- When startled, baby will throw head, back extend arms and legs, then retract arms and legs
- Plantar Grasp: disappears at 9mo -1 year
- Babinski Reflex: disappears at 1 yr
- ”
Acrocyanosis
- immediately after birth in healthy infants
- Lasts 24-48 hours
When do you do an anemia screening?
12 mo
