Objective Orthorexia nervosa (ON) is an excessive fixation on the
consumption of healthy food and an obsession with its biologi-
cal purity. The aim of this study was to assess the prevalence of
ON in a population of Polish urban adolescents and some possible
contributory factors.
Method Validation and adaptation of the ORTO-15 Question-
naire was made in the group of 399 participants (15–21 years old).
The validation procedure incorporated three basic methods to be
applied in the reliability analysis. The reliability analysis of the
ORTO-15 Questionnaire based on repeatability of the responses
presents a very good (kappa: 0.81–1.00 for 5 items) and a good
repeatability (kappa: 0.61–0.80 for 10 items). The reliability anal-
ysis based on the value of the Cronbach’s ˛ reached a satisfactory
level (0.7–0.9). The ORTO-15 questionnaire was considered a reli-
able tool to identify the risk of ON in population studies in the group
of urban youth aged 15–21. Assessment was made among 1899
high school students, 992 girls, and 907 boys, aged 15–21 years.
Results The mean value of the ORTO-15 was 39.2 ±3.6 points,
with no sex difference. Themain factors connectedwith orthorexia,
according to the “Orthorexia 35” definition were excess weight,
sporting activities, out-of-school activities, smoking status, work-
ing parents and a high family income.
Conclusions This study, of a large number of adolescents, showed
a prevalence of ON similar to that recorded in adult populations.
This is a first assessment of orthorexia among adolescent popula-
tion.

Introduction There is a low prevalence of eating disorders among
men. In many cases, the disorder arises as a means of avoiding
psychosocial maturation. Various psychiatric comorbidities such as
depression or obsessive-compulsive disorder are frequently found
in these patients.
Objectives To analyze psychiatric symptoms in relation to a case
of anorexia nervosa.
Methods Pubmed revision on clinical presentation of anorexia
nervosa in male. Review of patient medical records.
Results A 23-years-old male with diagnosis of restricting
anorexia nervosa was treated and followed since 2012. In July
2015, the patient, who was clinically stabilized for a year, had
decreased gradually intake. Suddenly he showed a decreased con-
sciousness, followed by an absence of response and mutism that
motivated hospital admission. The diagnosis was dissociative stu-
por. A research inwomenwith eating disorders shows a prevalence
of pathological dissociation between 4.8 and 48.6%. After recov-
ering a normal consciousness, he presented clinical features of
anorexia nervosa according DSM 5 criteria. The patient remained
two months until he reached his previous BMI (17) to continue
an outcome treatment. Despite of several years of specific treat-
ment for anorexia nervosa, both parents and patient still did not
accept the diagnosis. Cultural constructions of eating disorders as
a “women’s illness” mean that men may fail to recognise their dis-
order.
Conclusions There is a delay of diagnosis of anorexia nervosa in
men. The lack of research on men’s experiences and the cultural
construction of anorexia nervosa as a female problem may con-
tribute to underdiagnose eating disorders in men.

Introduction Anorexia nervosa (AN) is severe and debilitat-
ing psychiatric illness characterized by destructive weight loss
behaviour, refusal to maintain body weight at or above minimal
normal weight for age and height, intense fear of weight gain and
disturbance in experience of body shape and weight.
Objectives The purpose of this review is to investigate the state of
art concerning the use of atypical antipsychotics (SGA) in the treat-
ment of anorexia nervosa, comparing the efficacy and tolerability
in female patients not selected by age.
Methods A Medline enquiry of published articles from 2005
to October 2015 was performed using the following Key-
words: “anorexia nervosa; pharmacological treatment; atypical
antipsychotics; olanzapine; risperidone; paliperidone; aripipra-
zole; quetiapine”. Reviews and RCT were also analyzed.
Results No strong evidence of beneficial effects was found in
using SGA in adults. The majority of studies focused on olanzap-
ine, which seems to have, in some studies, only positive effect on
body mass index, eating disorder symptoms and functional impair-
ment. Risperidone doesn’t seem to have effect on body mass index.
Olanzapine and risperidone increase the mean fasting glucose and
insulin levels. In a recent study the main finding is represented by
the positive effects of the adjunct of aripiprazole to antidepressants
on eating-related obsessive-compulsive symptomatology.
Conclusions In conclusion, in our review we observed that
research in treatment with SGA of AN is still far away from finding
univocal conclusions.
