What is Precocious Puberty?
Refers to early onset of puberty usually before the age of 8 years in gils and 9 years in boys.
- Early onset of puberty in girls before
- age 8 and boys before 9 years
- The child will have secondary sex
- characteristics, accelerated growth rate, and advanced bone maturation
Diagnosed through H&P, labs, xrays
- Treated with GnRH
- agonists monthly IM or intranasally to suppress
- At risk for child sexual abuse—encourage
- parents to promote friendships with peers of the same age
What causes premature appearance of secondary sexual charactristics accelerated growth rate and advanced bone maturation?
What is the major consequence of precocious puberty?
Rapid bone growth which causes early growth plate fusionn and ultimately short stature in adulthood.
What is the definitive test to diagnose between central and peripheral Precocious puberty?
The gonadotrpoin releasing hormone (GnRH)
What is the aim of treatment in PP?
To stop or reverse the development of secondary sexual characteristics and to maximize adult height.
Why are girls with PP at greater risk for sexual abuse?
Because of their mature apperance.
Even though a child with PP looks older how should they be treated?
According to their chronologic age.
What is growth hormone deficiency?

Excercise precations with DM?
- working out when insulin is peaking
- carbohydrates pre-workout (15-30 grams)
- glucose frequently
- continue to burn energy post exercise—HS snack
When to monintor Glucose?
- prolonged or new exercise program
- 0200 if hypoglycemia is suspected
- for children 80-180mg/dl pre-meal and for infants/toddlers 80-200mg/dl
considerations in DM
- with carbohydrates
- of control with food choices
- tantrum or hypoglycemia?
School aged considrations in DM?
Can understand simple explanations
- Diabetes didn’t happen “because you were
Willing to try new foods
Often distracted when eating
- More at risk for hypoglycemia due to
- activity level
Adolescence with Dm?
Want to be in control
- Middle adolescence more prone toward
- risk-taking and challenging parents—this could mean missed injections, skipped
- testing, irregular meals, splurging on food
Late adolescence with DM?
- may have trouble relinquishing care
- motivated by predictions of complications
- on the here and now
Sick day care in DM?
Never skip insulin
Test more often
Test for ketones
Hydrate with no calorie drinks
- If unable to eat, use simple
- carbohydrates in liquid form
- ER warnings—”fruity breath”, N/V, deep and rapid respirations, decreased LOC, +
- persistent hyperglycemia.
