Growth Disorders Lecture Powerpoint Flashcards
Interpretation of percent of ideal body weight
110-120% overweight
>120% obese
90-110% normal variation
<70% severe wasting
Global developmental delay (GDD) includes these 3 things
Head circumference
Height
Weight
___ or ___ growth rates are rarely normal and warrant further investigation
accelerated, slowed
Most apparent growth abnormalities are a result of….
….inaccurate data - not measuring accurately, normal to weigh or measure those under 2 without clothing
A single value alone on a growth chart is of…
….limited value - its the rates being persistently low or high that are indicators of abnormality
Causes of increased weight in pediatrics (2)
- endocrine disorders (hypothyroid, cushings, thalamic or pituitary)
- overnutrition
Causes of decreased weight in pediatrics (4)
- undernutrition
- psychosocial deprivation
- hypothyroidism
- deficiency in nutrient
Initial assessment tests for weight changes in pediatrics (4)
- thyroid tests
- cortisol tests
- cbc
- ferritin levels
Krabbe disease
Globoid cell leukodystrophy, rare and often fatal lysosomal storage dz which results in progressive damage to the NS, involves dysfunctional metabolism and inherited in autosomal recessive pattern
Common conditions associated with increased head circumference (4)
- familial
- hydrocephalus
- nervous system dz
- metabolic storage disease such as krabbe
Common conditions associated with decreased head circumference (5) (usually pathologic)
- familial
- prenatal insult
- fetal alcohol syndrome
- maternal infection (TORCHES viruses)
- chromosome defects
Diagnostic evaluation of microcephaly (4)
- Maternal phenylalanine level
- karytoype of child for suspected congenital abnormality
- head imaging
- serum titers
Common conditions associated with increased height (3)
- hyperthyroid
- klinefelters
- marfan’s syndrome
Common conditions associated with decreased height (4)
- chronic anemia
- turners syndrome
- rickets
- psychosocial deprivation
How to determine height from parents
Girls 5 inches less than mean paternal height, boys 5 inches taller than mean maternal height
1 cause of short stature
short parents
Neonatal jaundice is caused by what type of bilirubin?
Nonconjugated
Any child growing ___ annually between 3 and puberty should be considered abnormal
<1.75’’
Radiographic evaluation of bone age to chronologic age
Bone age > chronologic then final height < predicted
Bone age < chronologic then final height > predicted
U/L ratio
Upper body segment divided by lower body segment, higher U/L ratio characteristic of short limb dwarfism or bone disorders such as rickets
Familial short stature bone age is ___, constitutional delay bone age is ___
normal, low
Is detnal development correlated with estimations of growth and maturation?
No - might instead suggest poor hygeine, trauma, or metabolic disturbances
Treatment of abnormal growth (1)
-synthetic human growth hormone
