African, Mediterranean, middle eastern, Indian, or Caribbean ancestry. Anemia, elevated
retic count, usually jaundice. Recurrent episodes of musculoskeletal or abdominal pain.
Often hepatomegaly or splenomegaly that resolves. Increased risk of bacterial sepsis.
Cornerstone of treatment: patient & family education, comprehensive outpatient care,
appropriate treatment of acute complications.
Hypothyroid Congenital & Acquired - ✔✔Essentials of diagnosis and typical features:
Growth retardation, decreased physical activity, weight gain, constipation, dry skin,
cold intolerance, and delayed puberty.
Untreated congenital hypothyroidism: thick tongue, large fontanels, poor muscle tone,
hoarseness, umbilical hernia, jaundice, and intellectual retardation. T4, FT4, and T3 resin
uptake are low; TSH levels are elevated in primary hypothyroidism.
Screening: Newborns are screened, any abnormal should be confirmed with venous T4 and
TSH level.
Treatment: Levothyroxine is the drug of choice.
PKU (phenylketonuria) - ✔✔Essentials of diagnosis and typical features:
,Intellectual disability, hyperactivity, seizures, light complexion, and eczema characterize
untreated patients. Newborn screening for elevated plasma phenylalanine identifies most
infants. Early diagnosis and treatment with restrictive diet prevents intellectual disability.
Lead - ✔✔Children with lead toxicity are typically asymptomatic. High lead levels (>70)
can cause severe health problems such as seizures and coma.
CDC recommends universal lead screening for children at ages 1 and 2 and targeted
screening for older children living in communities with a high percentage of old housing or a
high percentage of children with high lead levels.
A venous blood sample is preferred over a capillary sample.
Chelation of lead is indicated for levels over 45 and is urgently required for levels over 70.
With any level >5 rescreening should be performed at recommended intervals.
Iron deficiency - ✔✔Most common nutritional deficiency in the US
Risk factors are preterm or low birth weight, multiple pregnancy, iron deficiency in the
mother, use of non-fortified or cows milk before age 1, infant diet low in iron containing foods.
Infants and toddler consuming more that 24oz of cows milk are at risk as well as children with
chronic illness, restricted diet, or extensive blood loss.
Universal screening for anemia should occur at 12 months by obtaining a H&H, premature
or low birth weight may need testing before 6 months.
Hypercholesterolemia & Hyperlipidemia - ✔✔Non fasting lipid screen is
recommended universally for children between 9-11.
Fasting is recommended between 2-8 and 12-16 if risk factors are present.
Diet and weight management are primary interventions, for severe dyslipidemia (>190 LDL)
pharmacologic therapy should be considered. (>160 if family hx, >130 depending on level
and risk factors.)
Tuberculosis - ✔✔Risk should be assessed at well child visits and screening should be
based on high risk status.
,High risk defined as: contact with a person with known or suspected TB; symptoms or
radiographic finding of TB; birth/residence/travel to area with high prevalance of TB;
contact with HIV/AIDS person, prisoner, illicit drug user, homeless.
Dental health - ✔✔By six months every child should have a caries-risk assessment.
Streptococcus mutans- key organism in dental caries.
Primary teeth generally erupt at 7 months, but may appear as early as 3-4 months and as
late as 12-15 months.
Complete set of primary teeth present at 30-36 months.
Application of fluoride varnish starting at 6 months with first tooth and at every well child visit.
