CASE # 3
Over the past 6 months,
Marianne, a 15 year old girl in
your practice, has missed 8
days of school because of
severe, episodic lower
abdominal pain that coincides
with menses. Menarche was at
age 13 and menses are regular.
She states that she is not
sexually active. Findings on
physical exam are normal.
QUESTIONS
• What is your differential
diagnosis?
• What will you look for on
physical examination?
• What actions would you take
next?
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 #5
Mark is a 15 year old boy who
comes to your office for a routine
physical examination. His mother
asks to meet with you alone and
says that a few weeks ago she found
a plastic baggy with marijuana under
his bed. She requests that you
perform a drug test without telling
her son.
QUESTIONS
• Will you perform the drug test
without telling Mark?
• If not, what will you tell Mark as
an alternative?
• What will you tell Mark about
drug testing?
Substance Abuse
• Definition: The persistent use of
illicit substances despite
experiencing negative
consequences from their use.
Substance abuse is a multidimensional 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.
QUESTIONS
• What is your differential
diagnosis?
• What will you look for on
physical examination?
• What actions would you take
next?
Risk Factors for Illicit
Drug Use
• Family Tolerance
• Peer Influences- The most positive
predictor of drug and alcohol use
among teens, is a positive history of
use among peers.
• Other Factors
• Early Academic Failure
• Isolation
• Criminal Activity
Recognizing Substance
Abuse Problems
• Behavioral Change
• Unexpected Decline in School
Performance
• School Problems & Behavioral
Concerns
• Isolation from peers
• Outbursts of anger or abusive
behavior without remorse
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...
Lead Ins…..
• 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 CAGE
• C = the need to CUT DOWN
• A = has someone been
ANNOYED because of alcohol or
drug use
• G = have you felt GUILTY
because of something which
happened
• E = have you ever used in the
morning as an EYE OPENER
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 doctorpatient relationship.
• The AAP does not endorse such
“non-informed” screening.
Drug Screening...
• Obtain the appropriate sample
• Either urine or serum are adequate
for general screening.
• The use of hair for screening is
more sophisticated than generally
necessary for routine screening.
Drug Screening...
• How long will drug screening
remain positive ?
•
•
•
•
•
•
Amphetamines- < 48 hours
Barbiturates- 3-4 days
Cocaine- 2-4 days maximum
Ethanol- 2-14 hours
Opiates- 2 days
Cannabinoids- 10 - 20 days
maximum

and if not, the mother requests that
you start her on some form of
contraception.
