Adolescence and Female Puberty Flashcards

1
Q

What is the first sign of puberty in females?

A

Breast and papilla buds begin (thelarche)
- usually in SMR 2 (11.5-13 yrs)

there is 5% of females that develop pubarche first, but the majority is thelarche

  • *also can show physiologic leukorrhea at the same time (clear vaginal discharge)**
  • signals onset of menarche within 6 months

Q

When does menses usually begin

A

Usually within 3yrs after thelarche (3-4 SMR)

  • ages 12.5 is average
  • age range = 9-15 yrs

Timing is almost always determined by genetics
- can also be influenced by obesity, chronic illness, nutritional status and physical/psychosocial environment

Early menarche is usually anovulatory and have irregular cycles (range from 21-45 days with 3-7 days of menstration)

A

peak height velocity is usually at SMR 2/3, roughly 6 months before menarche is to begin

PHV = 8-9cm/yr

Growth spurt begins dismally and comes centrally

Q

Normal menses

A

21-35 days between 1 period -> next period

  • during first 3 years are superior irregular though
  • if periods are being skipped need to work this up

Normal menses actually lasts <7 days usually

Normal menstration should be 6 or fewer soaked pads or tampons per day

Average age of menarche = 12.5 yrs

  • slightly older for non-Hispanic whites
  • slightly younger in blacks and Hispanics

11
Q

When to evaluate for puberty delay

A

Lacks any signs of puberty by age 13

In sexual active patients with symptoms of pathology with 1 or 2 missed cycles

In patients whose breast development started between 8-9 yrs old
- usually observe for 3 yrs first and then go from there

Q

Causes of primary and secondary amenorrhea

A

Pregnancy

Functional hypothalamic causes (stress, weight loss, malnutrition, etc)

Female athlete triad

Eating disorders

Premature ovarian insufficiency

Hypothalamic or pituitary damages

Thyroid disease (both can cause by hypo is more likely)

Prolactinoma

Systemic diseases (sickle cell, CF, celiac, IBD, congenital heart disease)

Hyperandrogenism (POCS and adrenal hyperplasia/tumor)

Drugs and medications (atypical antipsychotics and hormones are most common)

Tuner syndrome

Anatomic abnormalities

  • imperforate hymen
  • transverse vaginal septum
  • mullarian abnormalities

Constitutional delay

Q

Treatment of menstral abnormalities

A

Usually need to refer out or work together with other professions to actually get the disorder under control
- depends on the issue

Q

Amenorrhea/PCOS treatment in children

A

OCPs (combo of estrogen and progesterone)

Lifestyle modifications = obesity and insulin resistance treatment

Patient with abnormal glucose tolerance (2 hr OGTT shows higher than 150) = metformin

Spironolactone for hirsutism if present

16
Q

Amenorrhea/eating disorders treatment

A

1st line = normalizing weight and improving nutritional status

2nd line = short term use of transdermal estrogen (E2) therapy (must fail first line first!)

17
Q

Amenorrhea/ovarian insufficiency treatment

A

1st line = low dose transdermal estrogen at 10-12 yrs and then increase doses until you can put on OCP combo therapy

you need to put them on exogenous hormones to get pubertal development

18
Q

Secondary amenorrhea treatment

A

Not recommended to be put on OCPs initially
- this will mask the patients subsequent menstrual pattern

if they have normal estrogen levels, can be put on medroxyprogesterone 10mg daily in order to help induce shedding of the endometrial lining and prevent build up

19
Q

Turner syndrome (45 XO)

A

1: 2500 live-born phenotypic females are affected
- most Turner syndrome patients die in utero

Results in ovarian dysgenesis

Characteristics

  • short stature
  • delayed puberty
  • webbed neck
  • protuberant ears
  • low hairline in back
  • shield chest (widespread nipples)
  • short 4th metacarpal and nail hypoplasia
  • transient congenital lymphedema
  • normal developmental and intelligence (10% are not though)
  • coarctation of aorta and aortic dissection risk is increased**

always have ovarian dysgenesis which causes amenorrhea and infertility

  • *classically as infants show infantile congenital lymphadema also**
  • if you see this = work up with Karotype and other causes

Treatment

  • requires urgent cardiology evaluation with chest pain and aortic dilation present (usually need BP monitored)
  • endocrinologist diagnosis with somatropin or low dose oxandrolone supplement = growth development
  • estrogen replacement therapy = for secondary sex characteristics
  • **MOST are infertile no matter what(ovarian dysgenesis)
20
Q

Common organ anomalies with Turner syndrome

A

Bicuspid aortic valves, aortic coarctation = 45%

Renal agenesis or horseshoe kidney = 40%

Hypothyroidism = 5-10%

Osteoporosis and fractures

Central obestiy

21
Q

Growth delay in Turner syndrome

A

Usually begins in early childhood but often isnt picked up until 5-10yrs of age where the patient starts to fall off the growth chart/curve

22
Q

How long does it take on average for adolescents to seek health care after intimating sex?

A

6-12 months

- many become pregnant or acquire a STI during this time

23
Q

Tiers of contraceptive effectiveness

A

Tier 1:

  • most effective
  • <1 pregnancy per 100
  • includes IUDs and implants

Tier 2:

  • 4-7 pregnancy per 100
  • injectable contraception, OCPs, OC patches and vaginal ring

Tier 3:

  • least effective
  • > 13 per 100
  • male and female condom
  • diaphragm
  • withdrawal and sponge use
  • fertility awareness-based methods
24
Q

What are the most common methods of contraception used by teenagers

A

Condoms = #1

Then withdrawal And the pill in 3rd

most effective = IUD and implantable

25
Q

What should be encouraged in teenage girls

A

Duel protection

  • use depo, IUD, OCPs or implantable for pregnancy inhibition
  • use condoms for STI protection
26
Q

PCOS

A

Most common endocrinopathy affecting women in adolescence
- overproduction of theca cells and hyperinsulinemia due to excessive LH and decreased FSH (inhibin). Hyperinsulinemia causes decreased SHBG’s which increases free testosterone

Symptoms

  • menstrual dysfunction (primary, oligomenorrhea, dysmenorrhea)
  • androgenic alopecia (crown thinning of hair caused by excessive DHT)
  • hyperandrogenism
  • obesity
  • acne with resistance to treatments
  • metabolic disturbances
  • dyslipdiemia
  • depression

Needs a 3 syndrome criteria

  • hyperandrogenism
  • ovarian dysfunction
  • presence of ovarian cysts

also need to rule out other causes

27
Q

Lab testing in PCOS

A

Free testosterone is high

LH:FSH ratio is elevated (>2)

Always get TSH, thyroxine, prolactin, cortisol and estradiol levels to rule out other causes

always get 17-hydroxyprogesterone levels (usually high anyways but super high = may be CAH)

28
Q

Management of PCOS

A

Always first line = OCPs

  • can be combo or progestin pill only
  • if contraindicated to combined OCPS = progestin

If they want to try getting pregnant = clophrene or letrozole

Hirtuism - spironolactone add on

Hyperinsulinemia = add metformin

always recommend weight loss in obese PCOS patients
