Pediatric Endocrine Flashcards
What does a single point on a growth curve tell you?
How they plot on the curve on THAT DAY
Multiple points on a growth curve are needed to evaluate the growth pattern. What does that assess?
If the rate of growth is adequate!
How many points on a growth curve do you need to assess if the rate of growth is adequate?
MULTIPLE
Normal BMI
18.5 - 24.9
What is the normal linear growth rate for kids between 5 - puberty?
5 cm per year
2 inches per year
What growth parameters is the first to be affected in endocrine disorders?
Height/Length
What defines Delayed Bone Age?
Bone age is > 2 SD BELOW the chronologic age
What are the 4 parameters on a growth chart?
Height/Length
Weight
BMI
Head circumference
When should you be concerned when you are looking at a growth chart?
When points plotted start to deviate up or down from normal growth rate for that child
If the height starts to deviate up or down, what should you consider?
Endocrine disorder
If the weight starts to deviate up or down, what should you consider?
Calories or nutrition issues
If the head circumference starts to deviate up or down, what should you consider?
Brain, skull, hydrocephalus
What defines Short Stature?
Height is > 2 SD BELOW mean for age/sex
Short Stature is below what percentile?
3rd percentile
What is seen with Familial Short Stature?
Parents are small
- Child grows with normal velocity but is simply lower on the curve
Familial Short Stature end height?
Mid-parental height
What is the Bone Age with Familial Short Stature?
Bone age is consistent with chronological age
What is seen with Constitutional Short Stature?
Plotting low on the growth curve and puberty is delayed
With Constitutional Short Stature, what will be in the family history?
Late bloomers – delayed puberty and growth
With Constitutional Short Stature, when will growth and puberty occur? End height?
LATER than normal
– End height = normal
What is the Bone Age with Constitutional Short Stature?
Bone age is DELAYED
What is the Bone Age with Idiopathic Short Stature?
Bone age is consistent with chronological age
If a child presents with short stature, what are 2 things to measure?
IGF-1
IGFBP-3
If a child presents with short stature, what are 2 things to measure and what are they?
IGF-1 = mediator of GH IGFBP-3 = blood transport protein for IGF-1
