Introduction OCD is one of the most frequently diagnosed dis-
orders during childhood. A prevalence of 1% is estimated, but
according to the literature is an underdiagnosed pathology.
Aims To differentiate pathological rituals from those that
children can have as normal behavior during their natural devel-
opment. To perform a differential diagnosis and a current review
of the literature.
Methods Descriptive analysis of a patient’s medical record diag-
nosed of OCD and Tourette syndrome.
Case report Eight years oldmale diagnosed of Tourette syndrome
(vocal and motor tics). Obsessive thoughts cancer related, self-
examinations with compulsive pattern and anxiety with social
and academic interference. Family history of tics in both par-
ents during childhood. Currently, father with order rituals and
mother with an Anxiety Disorder in treatment. Treatment with
Sertraline 25mg/day was tested with poor tolerance. Currently,
the patient is being treated with Aripiprazole 1mg/day with an
important improvement of his symptoms and quality of life. OCD
has comorbidity with affective and anxiety disorders, as well as
Tourette syndrome. It’s essential to differentiate pathology from
certain behaviors considered normal during a child’s development.
For example, some children can have certain level of meticulous-
ness, insecurity or a lucky object, but these behaviors shouldn’t be
confused with OCD symptoms. The treatment of choice is a combi-
nation of CBT with pharmacological therapy.
Conclusions An early diagnosis during childhood together with
an appropriate comorbidity detection can reduce the tendency
towards chronicity of this disorder leading to a better quality of
life in these patients.

Introduction Koro syndrome is a culturally related disorder char-
acterized by intense anxiety that the penis (vulva or nipples
in females) is shrinking or retracting and will recede into the
body. Usually it occurs in epidemics in Southeastern Asia, being
extremely rare in western countries. The condition is more com-
mon in males and is classified within Obsessive Compulsive and
Related Disorders.
Case report A 27-year-old single man was referred to the psy-
chiatric department. By the age of 23, he began worrying that his
penis was shrinking and retracting into the abdomen. He described
these thoughts as intrusive, ridiculous and repetitive. During the
first months the thoughts were not very disturbing but he progres-
sively developed an urge to verify the length of his penis several
times a day. To diminish the anxiety provoked by the obsessive
doubts on penis length, he started to have repetitive thoughts and
mental images about sexual acts, to consume pornography com-
pulsively and to increase his masturbatory behaviors (from some
times a week to several times a day). He described those thoughts
and behaviors as unpleasant and uniquely driven to reduce anxiety
provoked by obsessions.
He was prescribed fluvoxamine 200mg/day and initiated cognitive
behavioral therapy with good response. Y-BOCS score decreased
from 30 at initial evaluation to 18 after 3months of treatment.
Conclusions Koro syndrome is a very rare condition in psychiatry
in western countries, usually presenting secondarily to other psy-
chiatric disorders. Awareness of this diagnosis and knowledge on
its management are critical to provide optimal care to patients.

Introduction In the last decade, accumulating evidence has been
produced on the role of dissociation in Obsessive Compulsive Dis-
order (OCD). Understanding which dissociation dimensions are
specific to OCD could suggest the integration of therapeutic strate-
gies for dissociation in the treatment of patients with OCD.
Objectives The current study explored the role of dissociation in
a sample of patients with OCD, patients with anxiety disorders and
healthy controls with the aim to understand which dissociation
dimensions could be specific to OCD.
Method One hundred seventy-one participants were included in
the study (56% females, mean age = 35.96, SD = 12.61), of which
52 were patients with primary OCD, 59 were patients with Anx-
iety Disorders (AD), and 60 were healthy controls. The Dissociative
Experiences Scale (DES), BeckDepression Inventory-II (BDI-II), Beck
Anxiety Inventory (BAI), Yale-Brown Obsessive Compulsive Scale
(Y-BOCS) were administered.
Results Patients with OCD had significantly higher dissociative
amnesia symptoms than patients with AD and health con-
trols (F = 6.08, P < 0.01) and higher depersonalization/derealization
symptoms than healthy controls but not than patients with AD.
Patients with OCD did not report significantly higher dissociative
absorption than healthy controls and patients with AD.
Conclusions Strategies targeting dissociative amnesia and deper-
sonalization/derealization symptoms in OCD are discussed. Future
studies should examine which OCD subtypes are more strongly
associated to dissociation dimensions.
