that in large groups’ studies of adolescents treated with selective
serotonin reuptake inhibitors there have been no evidence of
increased suicidal risk.
Objective Understand if there is a significant association between
antidepressant treatment and suicidality in a 3-months follow-up
study of the adolescent’s consultation of Centro Hospitalar Lisboa
Norte.
Methods Analysis of 81 adolescents with an initial diagnosis of
major depression treated with an antidepressant for at least 3
months.
Results After the follow-up period there has been an improve-
ment in sadness in 92.6% of the adolescents, a remission of death
thoughts in 98.8% and an absence of suicides attempts. In 61.7%, it
was necessary to introduce also an antipsychotic in a low dose and
in 12.3% another antidepressant with a hypnotic effect.
Conclusion It is clear that untreated major depression car-
ries significant suffering and disability. Although treatment with
antidepressants may take several weeks before clinical improve-
ment appear and depression may worsen in the first days, its
therapeutic effect should not be underestimated even if becomes
necessary to add another medication in the first days. In evaluat-
ing these kinds of concerns, we must always differentiate between
media hype and scientific data.

Introduction Since the mid-1990s, the diagnosis of bipolar disor-
der has increased significantly: two-fold among adults, four-fold
among adolescents and 40-fold among children. Mood instabil-
ity is a hallmark symptom of many psychiatric disorders but does
not imply necessarily a diagnosis of bipolar disorder. Misdiagno-
sis is not just an academic issue: mood stabilizers have significant
adverse effects and expose patients to side effects that range from
mild to potentially life-threatening.
Objectives Discuss the potential overestimation of bipolar diag-
nosis in the adolescent population through a statistical analysis of
a sample from the adolescence’s consultation of Centro Hospitalar
Lisboa Norte.
Methods Analysis of 106 patients taking into account the initial
diagnosis and the diagnostic stability over 6 months. Non-
systematic review of the literature.
Results From this sample, 39.2% of the adolescents have a diag-
nose of unipolar affective disorder, 0.02% of bipolar disorder and
0.1% of disruptive mood disorder. These diagnoses did not change
over the follow-up period.
Conclusion It is important to try to understand the reasons of
this potential discrepancy (influence of pharmaceutical company
marketing, of parents’ desire, of doctors’ fear) to reduce controversy
and confusion and to adjust treatment.

Introduction In the last decade, international study attention to
the problem of risk of sexual behavior in adolescents has grown.
Some research has shown emotion dysregulation to be an impor-
tant predictors of forbidding outcomes for example alcohol and
drugs abuse or risky sexual behavior.
Objectives The aims of this study are analyze emotion dysreg-
ulation in adolescents and their belief regarding sex working of
adolescents.
Methods The sample is composed by 123 participants (58 male
adolescents, and 65 female adolescents, they is 14–15 years). All
participants completed a self-report questionnaire, Difficulties in
Emotion Regulation Scale. Them, participants responded to ques-
tions on prostitution.
Results Frequency analysis showed that 78% of participants
believe that prostitution is wrong; 1.4% of adolescents believe that
the voluntary prostitution is not wrong; 2.4% believe that prosti-
tution is not wrong if it can economically help their parents; and
4.9% believe that prostitution is wrong only if the customer is an
adult. Regarding emotion dysregulation, test t analysis highlights
some differences between male and female. The female presents
difficulties (P = 0.025) to strategies respect male adolescents and
they manifest a tendency to significative difference in impulse
(P = 0.061) and goals (P = 0.067).
Conclusions These preliminary results show that females may
experience greater difficulties to take functional strategies to reg-
ulate emotions and could risk adopting risky sexual behavior such
as prostitution.
