Katherine is a 14 year old female who presents
for a routine examination for sports. She has no
complaints. Her past medical history and family
history are unremarkable.

A 13 year old boy is seen in your office because of breast
enlargement over the past 6 months. He denies pain,
galactorrhea and marijuana use. He is taking no
medications. Physical examination reveals sexual maturity
rating (Tanner) stage 2 genitalia and pubic hair growth and
asymmetric breast buds beneath each nipple, with the left
measuring 1 cm and the right 3 cm. Of the following, the
most appropriate INITIAL management for this boy is:
1. Head CT with contrast
2. MRI of the abdomen
3. Serum beta-human
chorionic gonadotropin level
4. Reassurance that this is a
normal occurrence
5. Ultrasonography of the

Normal Menstruation

Normal menstruation is an indication that
the hypothalamic--pituitary--ovarian-uterine axis is intact and responsive.
Physiology of Menses


FSH - stimulates the maturation of
ovarian follicles
- directs the conversion of
androgens in the granulosa
cells of the ovary to estrogens
LH - stimulates theca cells of the
ovary to produce androgens
- midcycle LH surge stimulates
ovulation
Physiology of Menses


Estrogens- stimulate the proliferation of
endometrial epithelial and stromal cells.
Stimulate glandular formation.
Progesterone- produced by corpus
luteum, causes the endometrium to
function in a secretory manner, leading
to increased blood vessel growth and
tortuosity.
Normal Menstrual Cycles
Follicular Phase
Ovulatory Phase
Luteal Phase
Follicular Phase




Endometrial proliferation under estrogen
influence
Endometrial stroma becomes compact
Estrogen triggers midcycle LH surge
Cervical mucus is watery
Ovulatory Phase
Following ovulation, corpus luteum
produces both Estrogen and
Progesterone.
 Progesterone exerts suppressive
effect on Estrogen resulting in the
conversion of the endometrium to a
secretory state.

Ovulatory Phase
Vaginal secretions and Cervical
mucus are copious and clear.
 Secretions placed on glass slide
will demonstrate “ferning” pattern
when allowed to dry. (know this !)

Case # 3
(continued)
Upon further questioning, Marianne admits
that her last menstrual period was approximately
8 weeks ago. She is sexually active with a single
male partner and does not use condoms
consistently.

CASE #4
Adrienne is a 14 year old female who complains of
vaginal bleeding for the past month. She states that she
has been using approximately 6 – 8 pads per day and
that her bleeding has been heavier than usual.
Menarche was at 13 years. She denies sexual activity.

Substance Abuse

Definition:
 The persistent use of illicit substances despite
experiencing negative consequences from
their use.
 Substance abuse is a multi-dimensional
disorder with a complex biopsychosocial
etiology.
Multiple Drug Use
Adolescents rarely report a
“drug of choice” but rather use
multiple substances.
Age at First Use
The age of first use for US teens is
11-12 years of age.
Case #5
(continued)
Mark’s grades have been falling and he quit the
football team recently. He has a new group of friends
that he never brings home. Mark tells you that he
occasionally smokes marijuana but he denies using any
other drugs. He admits to being sexually active and
drinking beer with his friends on weekends.
His parents are concerned because they recently smelled
alcohol on his breath when he returned from a party.

suggestive of a serious problem with substance abuse?

Obtaining the History



With the teen separated from parent/s
With assurance that the substance use history is
part of a routine interview
(it should be!)
With appropriate lead in questions...
Many teens your age go to parties where alcohol is
available…do you?
 Have you ever consumed a drink containing alcohol?
 Have you ever been drunk?

The “C.R.A.F.F.T.”






C -- Have you ever ridden in a CAR driven by
someone (including yourself) who was "high" or had
been using alcohol or drugs?
R -- Do you ever use alcohol or drugs to RELAX,
feel better about yourself, or fit in?
A -- Do you ever use alcohol or drugs while you are
by yourself, ALONE?
F -- Do you ever FORGET things you did while
using alcohol or drugs?
F -- Do your family or FRIENDS ever tell you that
you should cut down on your drinking or drug use?
T -- Have you gotten into TROUBLE while you
were using alcohol or drugs
Drug Screening

Ethical Issues- screening without the
knowledge and consent will likely have a
negative effect on the doctor-patient
relationship.

The AAP does not endorse such
“non-informed” screening.
In the habitual user, which of the following substances is
MOST likely to be detected by a urine screening test up
to 1 month after last use?
