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.

Anxiety, stress and depression: A

comparison between anorexic, obese

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

Table 1 . T

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!

T. Carvalhao

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
