delusional disorders. Through two clinic cases and in a compara-

tive form, it is analyzedwhat are the aspects that make it difficult to

come up with an adequate distinguishing diagnostic, which are the

marks topoint out inorder to achieve it, once established, what sim-

ilarities and differences we observe in the adequate treatment of

both disorders. It is about a proposal not usual in our daily practice

of a consultation outpatient of a psychiatrist, but in these moments

it is what is presented, we have to stand up, to not fall for the error.

Introduction

Compulsive skin picking and trichotillomania are

both impulse control disorders, characterized by the need or urge

to touch, scratch, scrub, friction, rub, bite, press or dig in the skin;

it is often an answer to minimum skin defects or to mild acne. The

resulting tissue damage can be moderate to severe.

Objective

Case report of a woman with Skin picking resistant to

treatment.

Methods

Clinical observation.

Results

43-year-old woman who was admitted in emergency in

June 2014 because of her skin lesions. After observation by Der-

matologist she was sent to the Psychiatric due to injuries caused

by her. She referring compulsion to scratch, bite and tear the skin

since she was 3 years old. After introduction of psychotropic drugs,

the patient was referred to the Psychiatric consultations. After 1

year consultation there is some clinical improvement.

Conclusion

Despite clinical advances in psychiatry, the Skin Pick-

ing disease is still little known today, requiring more research and

knowledgement in terms of phenomenology and of treatment.

Obsessive-compulsive disorder (OCD) is a severemental illness that

causes significant stress in children and adolescents. It is possi-

ble to infer three distinct etiologies – neurobiology, environment

and dysfunctional interpretative patterns. Certain characteristics

are attributable to OCD with onset in childhood or adolescence as

higher prevalence in males, increased frequency of isolated com-

pulsions (more cleaning, repeating and checking), higher rate of

aggressive obsessions and more common accumulation behaviors.

There are several psychiatric comorbidities associated with OCD

like anxiety disorder andmajor depression. The first-line treatment

in OCD is the association of a selective serotonin reuptake inhibitor

(SSRI) and individual psychotherapy.

The authors reviewed the clinical records of patients diagnosed

with OCD observed in a child and adolescence psychiatry liaison

consultation between April and September 2015, inclusive, aiming

to characterize the sample, to describe the typical clinical picture

and to evaluate the existence of physical and/or psychiatric comor-

bidities, comparing the results with those expected in literature.

The typical patient profile found was a 12-year-old male, liv-

ing with relatives, with no neonatal complications, with stable

home environment, without family psychiatric history, with asso-

ciated medical comorbidities, with age of onset symptoms at 10.5

years-old, with only an obsession (contamination), with only a

compulsion (cleaning or checking), with psychiatric comorbidities,

treated with SSRI and without psychologyaccompaniment.

There are some limitations that must be taken into account because

the sample was taken from a liaison psychiatry consultation, but in

general terms, the results were similar to those described in the

literature.

Introduction

An association has been observed between obses-

sive symptoms in Obsessive Compulsive Disorder (OCD) and

psychotic symptoms in schizophrenia, being sometimes difficult to

establish a clear limit between them. The term “schizo-obsessive

disorder”was proposed to describe the resulting disorder of comor-

bidity of OCD and schizophrenia, although it has not been definitely

settled.

Objective

To analyze the incidence of coexistence of OCD and

schizophrenia symptoms and the way it modifies the treatment

and prognosis of the illness.

Method

Reviewof some articles published inMental Health jour-

nals such as “Salud Mental” and “Actas Espa˜nolas de Psiquiatría”.

Results

Some studies about psychotic patients have determined

15% as the average of comorbidity of OCD and schizophrenia. The

probability of having OCD is six times bigger if there is psychotic

pathology associated.

The fact that obsessive and psychotic symptoms get together in

some patients shades the prognosis bringing more negative symp-

toms, more depressive humor, a larger cognitive impairment, more

resistance to treatment and more relapses than we can observe in

OCD and schizophrenia isolated.

The pharmacological treatment usually consists in neuroleptic plus

anti-obsessive drugs, together with cognitive-behavioral therapy.

Sometimes, when there is a very bad evolution, it is required to

consider psychosurgery as one necessary option, even though its

use in this context is not much widespread.

Conclusions

The simultaneous presence of OCD and schizophre-

nia is more common than we could expect only by chance and

makes the prognosis worse, being difficult to find a truly effective

treatment.
