of 13 referred by her pediatrician and suspected to have an eating
disorder. R. lived with her parents and an older sister. The patient
suffered an underweight below the healthy and a distorted per-
ception of her body among other symptoms. She has gone through
several specialists and treatments including day hospital since her
first entrance at the hospital.
The flexibility and cooperation between the different therapists
involved in the treatment is essential for a good outcome of the
patient. There are many factors that can have an influence in
the treatment, like the reluctance to the treatment, the counter
transference feelings that the therapy can cause and the way of
relationship. These factors can often cause situations of confusion
and misunderstandings between the different professionals who
attend the patient, who have to be well coordinated. Not to forget
is that the biggest loser of all is the patient itself.

Introduction Several reviews have reported the incidence of
schizophrenia in patients with eating disorders (ED) to be between
3–10% and the incidence of transient psychotic episodes to be
10–15%. On the other hand, anorexia nervosa appears to affect 1
to 4% of schizophrenia patients. Reports of psychosis and ED occur-
ring in the same patient have led to various views as to the nature
of the relationship between the two.
Objective Analysis of the literature illustrated by different clin-
ical cases in which appears to be a relationship between ED and
psychosis.
Aims Critical reflection about the hypothesis that could underlie
the comorbidity of psychotic illness and ED.
Methods Non-systematic review of a literature search using the
keywords: eating disorders; psychosis; comorbidity.
Results There is no consistent sequence in the co-occurrence of
the two conditions – ED sometimes precede and sometimes fol-
lows the onset of psychosis. ED patients can develop psychotic
symptoms, most frequently transient in the course of the disorder,
while others are subsequently diagnosed with a chronic psychotic
disorder. On the other hand, patients with a primary psychotic ill-
ness can develop an eating disorder. The connection between the
two, however, remains speculative, considering the hypothesis that
ED and psychosis can be entirely separate disorders that can, by
chance, occur in the same person.
Conclusions The area of comorbidity and overlapping symptoms
in psychiatry requires more deep research. Despite evidence from
case series, the comorbidity between ED and psychosis is poorly
understood, and firm conclusions cannot be drawn from this anal-
ysis.

and healthy control women

Italy
Introduction Several studies have proved that people who suffer
from Anorexia Nervosa (AN) experience higher levels of anxiety,
stress and depression than general population; while controversial
results have been found among obese people (OB); the purpose of
this study is to compare levels of anxiety, stress, and depression in
AN sample, in OB sample and in Healthy Control Group (HC).
Methods AN sample: 27 anorexic inpatient women in an eating
disorder unit. OB sample: 27 obese women evaluated for elegibil-
ity of bariatric surgery intervention. HC group: 27 women from
different countries had been recruited. DASS 21 and STAI-Y ques-
tionnaires had been subministred to evaluate anxiety, stress and
depression. The questionnaires had been scores and statistical anal-
ysis had been held to determine whether the differences founded
in the 3 populations were significant or not ( P-value < 0.05).
Results he differences founded were significant.
Conclusion Anxiety and stress (DASS21, STAI): AN have reported
higher levels than OB and HC that present similar levels. Depres-
sion (DASS21): AN have reported higher levels than OB and HC; OB
higher levels than HC.

I’m really fat!

Hospitais da Universidade de Coimbra, Coimbra, Portugal
Introduction The eating disorders are changes in eating
behaviour associated with distortions in the self-concept and
self-image, pathological fear of getting fat, morbid motivation for
thinness and changes in appetite and its control, with or without
compensatory attitudes. In the DSM-5 and in the CID-10, the
two fundamental diagnostics are anorexia nervosa and bulimia
nervosa.
Purpose Characterization of the Portuguese population concern-
ing eating disorders incidence.
Methods Bibliographic revision through Pubmed until 2013,
using the keywords: anorexia nervosa, bulimia nervosa, eating
