Q

autism screening

A
  • Recommended for all children at 18 and 24 months of age.
    • Standardized tools are available:
      • M-CHAT (Modified Checklist for Autism in Toddlers is commonly used. (generally done at 2 years)
        • 23 question questionnaire
        • Abnormal responses trigger follow up assessments
        • Additional discussion of autism in a future lecture…
      • MCHAT is not diagnostic so they need to go for formal screening if they test positive

Q

anticipatory guidance

A
  • 15 and 18 month visits
    • Car Safety- rear-facing until 2 years of age or highest weight allowed by seat manufacturer
    • Household Safety- NO Walkers, Use smoke detectors, set hot water heaters < 120 degrees, childproof the house
    • Burn Prevention- Avoid hot soup/coffee around toddler
    • Tantrums and behavior (separate lecture)
    • Sleep routines and issues
  • Drowning Prevention- fence around pools

Q

anticipatory guidance: dental health

A
  • Begin Sippy Cup, off the bottle
  • See Dentist
  • Give fluoride if water not fluoridated
  • Fluoride varnish every 6 months. Offered in many pediatric clinics.
  • The sooner you can get a kid to a regular cup, the better
  • At this point they probably don’t have the hand control to drink out of a normal cup yet

Q

ingestions

A
  • The most common ingestions in children less than 6 yo is cosmetics and personal care products followed by cleaning substances.
  • Most ingestions that occur in young children were able to be managed at home and did not require an ED visit.
  • The detergent breaks down the cell walls and can cause very significant damage and scarring

Q

normocytic anemia and macrocytic anemia

A
  • reticulocyte count
    • normal & low
      • iron & vitamin deficiencies (including chronic blood loss)
      • chronic disease
      • marrow suppression/failure
      • red cell defects
      • intoxications
    • high
      • hemorrhage
      • hemolysis
    • She wont test on this because this is a more nuanced point about hyperbili
  • a “physiologic nadir” of hemoglobin (~11 g/dL) occurs near 8-10 weeks of life as erythropoiesis changes from fetal to normal

Q

A
  • differential diagnosis
    • iron deficiency anemia
    • hemoglobinopathy & hemolysis
      • thalassemia
      • sickle cell disease
    • chronic (inflammatory) disease
    • lead intoxication
    • copper deficiency

Q

iron deficiency anemia

A
  • why worry?
    • iron deficiency anemia associated with impaired mental and psychomotor development
    • iron deficiency increases lead absorption
    • We worry because of brain development – if you cant get enough O2 because you have low blood cells, you can have brain developmental delays

Q

epidemiology of iron deficiency anemia

A
  • 6-24 months of age
  • risk factors
    • born with low iron stores
      • maternal anemia
      • placental ‘transfusion’
    • breastfed and not supplemented with dietary iron
    • fed low-iron formula
    • switched to cow’s milk before 12 months of age
    • children over 12 months consuming large amounts of cow’s milk
17
Q

pathophysiology of iron deficiency anemia

A
  • most common cause of anemia
  • age range
    • prematurity (low iron stores) - anemia in first 0-3 months of life
    • normal term infants - 6-24 months of life as transition from breastmilk or formula to table foods
    • teenagers- chronic blood loss
18
Q

iron deficiency anemia screening

A
  • typically after first year of life
  • considered again before kindergarten
  • all adolescents (particularly menstruating females)
19
Q

signs and symptoms of iron deficiency anemia

A
  • signs & symptoms
    • mild anemia - usually asymptomatic
    • severe anemia - pallor, fatigue, heart failure
    • chronic iron deficiency anemia – apathy, irritability, poor concentration, associated with cognitive defects
  • laboratory
    • microcytic, hypochromic anemia
    • high RDW
    • increased free erythrocyte protoporphyrin
    • iron studies
      • decreased serum ferritin
      • low serum iron
      • elevated total iron-binding capacity
      • decreased transferrin saturation
  • RDW = size of the cell
  • High or wide RDW = high variability of the size of the cells
20
Q

treatment of iron deficiency anemia

A
  • Treatment
    • oral iron therapy
      • 4-6mg/kg/day elemental iron
      • reticulocyte count increases in 2-3 days
      • hematocrit typically rises ~1% per day
      • normal hemoglobin in 4-6 weeks
      • iron stores require 1-3 months to replete
  • prevention
    • diet counseling
    • infants receive iron fortified formula
    • breastfed infants over 6 months of age receive iron supplementation
    • menstruating girl can receive a multivitamin with iron
    • screening
  • Hgb should bump in one month and then continue to increase over the next few months
21
