Growth Hormone Deficiency - Clinical Signs:
Normal birth size but slow growth (<5 cm/year) below 3rd percentile by age 1.
Growth Hormone Deficiency Other Symptoms:
Hypoglycemic seizures, micropenis, undescended testes, neonatal jaundice
Growth Hormone Deficiency Diagnosis:
GH level tests, hand x-rays for bone growth, endocrine studies, family history
Growth Hormone Deficiency Treatment:
GH Injections, possibly other hormone replacements (thyroid, cortisone, sex hormones)
Growth Hormone Deficiency Considerations:
Bedtime injections for better effect, family support for body image and cost concerns.
Hypothyroidism Causes:
Primary (thyroid failure) or central (pituitary/hypothalamic dysfunction).
Hypothyroidism Symptoms in Infants:
Thick tongue, hypotonia, constipation, hoarse cry, large fontanelles
Hypothyroidisms Symptoms in Children:
Dry Skin
hair loss
bradycardia
cold intolerance
goiter
Depressed deep tendon reflexes
decreased appetitie
Hypothyroidism Diagnosis:
Increased TSH
decreased T3/T4.
Hypothyroidism Treatment:
Lifelong levothyroxine with dose adjustments.
Hypothyroidism Newborn Screening:
Prevents intellectual disability and growth delay.
Precocious Puberty Definition:
Early puberty (<9 in boys, <8 in girls).
Precocious Puberty Causes:
Adrenal/gonadal tumors
early activation of GnRH
No known cause 80% of boys, 50% of girls
Precocious Puberty Symptoms:
Tall for age
early secondary sex characteristics
advanced bone age
Precocious Puberty Treatment:
GnRH analogs (Lupron) to slow early puberty. Failure to treat can result in stunted growth as children with this have advanced bone age. Removing tumor
Precocious Puberty Concerns:
Advanced bone age leads to short adult stature if untreated.
Precocious Puberty Family Education:
Emphasize normal emotional development despite early physical changes, promote positive body image, family education
Precocious Puberty Assessment
tanner staging
height/weight
psychosocial - body image
Type 1 DM Cause:

10-14 years.
Type 1 DM Symptoms:
Polyuria
polydipsia
Weight Loss
Fatigue
Ketoacidosis
Type 1 DM Treatment:

glucose monitoring
Diet Control
