at what age is infant expected to regain brithweight
define failure to thrive
sings of generally adequate nourishment in first few weeks of life
regain brithweight by 2 weeks
-failure to regain birthweight by 3 weeks
-continuous weight loss after 10 days
= failure to thrive
-6 feedings per day
-at least 6 wet diapers per day
= signs of generally adequate nourishment
preferred feeding source for all infants
a rare exceptoin
human milk for all
HIV-infected mother is a rare exception, among others
average newborn weight loss in first few days of life, 2 SDs
6% birth weight lost in first few days on average
11-12% is two standard deviations (10% is typically used as red flag)
encourage this frequency of breastfeeds for newborn
e.g. offering the breast whenever the newborn…
encourage 8-12 feeds per 24 hrs
e. g. offering the breast whenever the newborn shows early signs of hunger
- increased alertness
- increased physical activity
- mouthing
- rooting
how to get an idea of adequacy of breast feeds for newborn
gaining weight
urine and stool output
6-12 wet diapers (half voids, half stools) in first week of life
feeding q2-3 hours for 10-15 minutes is average (concern if 4+ hours between feeds, shorter duration)
formal evaluation of breast feeding performance by trained observers 24-48hrs and 3-5 days after discharge
Vit D supplementation for newborns
breast fed
vs
formula fed
start 400IU vit D po within first few days for breast fed infants
(exclusively formula fed ingesting 1L or one quart of formula will get enough vit D)
Normal anterior fontanelle size
2cm avg diameter
.5-3.5 = 2 sd’s
Newborn hypotonia, large fontanels, an umbilical hernia, and jaundice
Think..
Congenital hypothyroidism
TF
Umbilical hernias and jaundice are more common in newborns with congenital hypothyroidism
T
common anyway, but more common w hypothyroid
Inborn error of metabolism
Pres
Prog
appear well for at least the first 1-2 days of life but then become symptomatic due to the protein load in breast milk or formula.
Initial signs include somnolence and poor feeding, usually followed by vomiting and lethargy.
Without treatment, patients develop a progressive encephalopathy.
Presentstion of hypoglycemia in a newborn
Asymptomatic Vs Hypothermic Irritable Jittery Tremors
S and s of intracranial bleed in shaken baby syndrome
AMS
hypotonia
Poor feeding
Large fontanelles
Bruising and retinal bleeding are possible comirbid signs of abuse (not specifically intracranial bleeding)
The most common form of congenital adrenal hyperplasia, 21-OH deficiency, causes decreased production of ____ and ____
Expect this in the first labs you order
Aldosterone
Cortisol
Hyponatremia
Hyperkalemia
(Salt-wasting)
Causes of congenital hypothyroidism
Iodine deficiency (world wide)
Aplasia hypoplasia ectopia
Mom’s autoimmune abs transplacenta transiently
Mom w graves antithyroid meds transplacenta transiently
Pres of congenital hypothyroidism
Usually a few months after birth because protected by mom’s thyroid home
Feeding problems Decreased activity Constipation Prolonged jaundice Skin mottling Umbilical hernia
With time, if untreated, large tongue, hoarse cry and puffy myxedematous facies.
intellectual disability. The longer treatment is delayed, the greater the risk.
Treat congenital hypothyroidism in newborn
Levothyroxine
- maintain TSH 1 μIU/mL (1mIU/L) and T4 in the upper half of the normal range for age
- aim for normalized TSH by 1-2 mos old for good neurologic outcome
- frequent follow-up
peds endocrinology consult
PKU
presentation
advice for pregnant women with PKU
normal at birth
then fail to attain early developmental milestones
develop microcephaly
progressive cognitive impairment
seizures
albinism
musty odor of sweat and urine (due to phenylacetate).
pregnant women with PKU, maintain low phenylanine levels to protect the developing fetus. Though the developing fetus may only be a carrier of the PKU gene, high intrauterine levels of phenylalanine can result in growth retardation, microcephaly, intellectual disability and congenital heart disease for the child.
So get newborn screening
why is early detection of sickle cell disease important
early institution of penicillin prophylaxis can prevent sepsis secondary to infection with Streptococcus pneumoniae.
A two-month-old female presents to clinic for a well-baby checkup. Mom has been happy because the “baby rarely cries and sleeps all the time.” On exam, the baby has yellowing of the skin, decreased activity, appears to have decreased tone, and a large anterior fontanel. What is the most likely diagnosis?
Congenital hypothyroidism
body temperature change, changes in respiration, increased or decreased heart rate, reduced movement, reduced feeding, low blood sugar, seizures, and jaundice
think..
sepsis (blood infection)
abnormal genitalia (females), poor feeding, vomiting, dehydration, and electrolyte changes think...
congenital adrenal hyperplasia
A 6-week-old infant girl whose family recently immigrated from Mexico is brought to clinic for “excessive sleepiness.” The mother states the infant is not easily aroused for feedings and is not as active as she was previously. She is also concerned about her daughter’s large “outtie” belly button. On exam, the patient is afebrile and jaundiced, with a puffy myxedematous face. The fontanels are large but flat. There is a large umbilical hernia. When asked about the results of a newborn screening exam, mom states that the screening was never performed. What would be an expected abnormal lab value(s) associated with her condition?
High TSH, low T4
A 45-day-old infant is brought in by his mother due to lethargy, constipation, and yellow skin color noted since birth. The mother and the baby moved to the U.S. from a foreign country that does not screen its newborns. The baby has been fed only formula since birth. Physical exam of the neonate reveals additional findings of large fontanelles, umbilical hernia, a large tongue, and abdominal distension. What is the next best step in diagnosis?
TSH
first year of life with hypotonia, lethargy, constipation, weak cry, eventually lead to respiratory failure. absent DTRs.
