Flashcards in W13_01 growth Deck (24):
1

what's the main growth factor in the intrauterine period of growth?

insulin

2

what's the main growth factor system after birth?

the hypothalamic-pituitary axis

3

what are the three general factors that may restrict intrauterine growth? (triangle)

fetal, placental, maternal

4

note: always correct for time in premature babies for a growth chart

ok. E.g. a 3 month baby that was 2 months early = 1 month baby

5

note: there's a special growth chart for turner syndrome females

it's shorter than the general population

6

note: the WHO growth curves use 0.1%-99.5%ile to describe normal

CPEG uses 3-97%ile

7

average birth head circumference?

35cm;
increases 12cm in first year, and 2 cm in second year

8

what defines childhood

from 3 years old until puberty

9

note: growth velocity might be more meaningful than absolute height

ok

10

how to calculate the midparental height

1/2*(father's height + mother's height plus/minus 12.5) if boy/girl

11

what's the first sign of puberty in females?

breast development;
then growth spurt;
menarche (growth almost complete)

12

when's the onset of puberty in females?

7-13;
early is common, late is rare

13

what's stage 2 of the tanner staging?

breast buds

14

what's stage 4 of the tanner staging?

areola protrude from breast

15

what's stage 5 of the tanner staging?

areola recede and stay flush with rest of the breast. Final stage

16

when's the onset of puberty in males?

9-14 years

17

what's the first sign of puberty in males?

testicular growth

18

what are the "four questions that provide all the answers?"

was the child IUGR?
Is the child disproportionate or proportionate?
Is the growth velocity normal or slow?
Is the bone age normal or delayed?

19

what's the the upper:lower segment ratio? (pubic symphysis is the dividing line)

1 to 1

20

what are the two very common normal slow growth velocity conditions

familial short stature;
constitutional delay of growth

21

are males or females more commonly affected by constitutional delay of growth?

males >>>>>>> femlaes

22

how to check the bone age?

image the child's left hand. Check for bone maturation (calcification) and compare to images of a reference age

23

what happens to the bone age for constitutional delay? For familial short stature?

CD: bone age is less than chronological age;
FSS: bone age is same as chronological age

24

which endocrine disorders could cause slow growth velocity?

hypothyroidism;
hypopituitarism;
cortisol excess
