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.

Introduction

Pathological Skin Picking (SP) is a psychiatric con-

dition with a 2–5%-prevalence in the community and consists

of repetitive picking behaviours associated to marked distress,
