Intro Flashcards
what is the result of estrogen crossing the placenta later in preg
may trigger the secretion of prolactin from the neonates pituitary gland
-may result in the benign proliferation of glandular tissue that starts as early as six weeks of fetal development (mastauxe)
what is mastauxe and two types
neonatal development of breast tissue
neonatal mastuxe- less than or equal to 3cm
Giant mastuxe- >3cm
What are some complications of mastuxe
Neonatal breast abscess
Neonatal astitis
neonatal galactocele (retained stagnant milk)
What is neonatal galactorrhea and presentation
babies secrete non bloody, milk like, cloudy fluid from the nipples
-occurs when estrogen and progesterone lvls decrease after delivery, enabling the secretion of prolactin from oxytocin from the neonates pituitary
what is adult mons pubis
swelling of fatty pad that overly the symphysis pubis
what does precocious puberty and what is involved in it
if any of the following develop before 8:
- development of breasts
- first period
- armpit or pubic hair
- begining to grow faster
- mature outer genetics
when does puberty start/what happens
- puberty begins with maturation of the hypothalamus and is controlled by the Hypothalamic-pituitary-gonadal axis
- HPG experiences a pulsatile release of Gonadotropin releasing hormone (GNRH) which stims pituitary gonadotropins and gonadal sex organs
when does puberty usually start in females and how long does it last
deemed physiological when it begins between 8-12 y
-usually lasts 3-4years and consist of a series of events that typically proceed in a predictable sequence
african american development vs Caucasian
found that AA girls develop 6-12 m before Caucasian girls
start menses 8 + 1/2 months prior to caucasian
early maturation in girls is associated w what
low self esteem less favourable body image greater range of eating probs depression suicide attempts higher risk of adult diseases (breast cancer/ endometrial cancer)
how much earlier is has thelarche (breast budding) occurring every decade
decreased 3m per decade
what are the 5 theories for early puberty
1, Leptin (increased in childhood obesity)
- Xenoestrogens
- Nutrition (high Sugar/refined carbs/high fat/low fib)
- decreased activity
5, rapid weight gain in infancy
concerns for early puberty (adult diseases)
obesity type 2 diabetes heart disease breast cancer depression behavioural disordeers
what is delayed puberty
clinically defined by the absence or incomplete development of sex characteristics by age 13
what is the absence of pub by 18 considered
hypogonadism (absence of activation of HPG axis)
