The aim of primary prophylaxis is to reduce the number of new cases, while secondary prophylaxis is to provide early diagnoses and treatment of cancer cases.

Interaction Between Val158Met Catechol-O-Methyltransferase Polymorphism and Social Cognitive Functioning in Schizophrenia: Pilot Study.

The Val158Met catechol-O-methyltransferase (COMT) functional polymorphism may influence social cognitive functioning in patients with schizophrenia. Aspects of social cognition were evaluated with the Facial Expression Recognition Test, the Voice Emotion Recognition Test, and the Reading the Mind in the Eyes Test. The Short Recognition Memory Test for Faces was used as a control measure.

[The newest therapeutic directions in the rehabilitation of patients with mental disorders].

In this paper, the authors attempted to present the comprehensive literature review on the newest therapeutic interventions such as cognitive remediation therapy (CRT), mindfulness-based cognitive therapy (MBCT), social cognition and interaction training (SCIT), and acceptance and commitment therapy (ACT) which appeared promising whilst their implementing among schizophrenic patients, patients with anxiety disorders, eating disorders, and affective disorders. In the presented work particular attention was focused on two kinds of psychotherapeutic interventions: social cognitive trainings and cognitive remediation therapy (CRT) and their effectiveness in the rehabilitation process of schizophrenic patients. The growing body of research based on application of the above mentioned techniques in psychiatric population gives remarkable hope to improve quality of cognitive and psychosocial therapeutic interventions and to set up both complex and comprehensive therapeutic programme for patients with mental disorders.

[Functional polymorphism of genes inactivating biogenic amines and cognitive deficits in paranoid schizophrenia].

Aim: The aim of the work was to assess relationship between gene polymorphism of enzymes influencing dopaminergic-, serotoninergic, and noradrenergic transfer and cognitive functioning of paranoid schizophrenic inpatients (ICD-10).

Method: The following methods have been used in the study: The Test of Everyday Attention (TEA) and The Visual Object and Space Perception Battery (VOSP), psychiatric scales (SAPS, SANS, BDI) and techniques of genetic engineering (PCR reaction, RFLP and VNTR techniques). Subject groups included 100 schizophrenic patients (57 male) and 50 healthy controls (20 male).

[The possibility or coercion treatment? Anorexia nervosa--legal regulations. A case report].

Anorexia nervosa is diagnosed on the basis of well-defined diagnostic criteria and requires treatment, as it is associated with the highest mortality rate of all mental illnesses. In Poland, anorexia nervosa is not considered a mental illness, although the opinion of researchers and clinicians are divided. To reduce the death rate of AN correct and early diagnosis, appropriate treatment starting immediately and the appropriate regulations to allow people to take the AN treatment against their will are necessary.

[Is Huntington's disease a neurological or psychiatric disorder? case report].

Huntington's disease is a rare, although commonly known neurodegenerative disease, caused by dynamic point mutation within the IT-15; it is inherited autosomally dominantly. IT-15 mutation includes multiple (36-250) repetitions of trinucleotide sequence (CAG) encoding a glutamine at the amino end of Huntington (mHtt). It is one of the nine polyglutamine diseases (PolyQ), characterized by a CAG repeat.

Social cognition and visual perception in schizophrenia inpatients treated with first-and second-generation antipsychotic drugs.

Purpose: Social cognition captures affect recognition, social cue perception, "theory of mind," empathy, and attributional style. The aim of our study was to assess social cognition in schizophrenia inpatients being treated with first-generation antipsychotic drugs (FGAs), n=28 (perphenazine and haloperidol, FGAs) or with second-generation antipsychotic drugs (SGAs), n=56 (olanzapine and clozapine, SGAs).

Subjects And Methods: Eighty-four patients completed the Facial Expression Recognition Test, the Voice Emotion Recognition Test, the Short Recognition Memory Test for Faces, and the Reading the Mind in the Eyes Test.

Attentional and emotional functioning in schizophrenia patients treated with conventional and atypical antipsychotic drugs.

Background: Effectiveness of antipsychotics in treating emotional and cognitive deficits in schizophrenia still remains controversial. The aim of our study was to assess emotional and cognitive functioning in schizophrenic inpatients currently treated with typical antipsychotics (perphenazine, perazine, fluphenazine, and haloperidol) and in another group of schizophrenic inpatients currently on atypical antipsychotics (olanzapine, risperidone, amisulpride, and quetiapine).

Material/methods: One hundred patients with DSM-IV schizophrenia or schizoaffective disorders (39 treated using typical antipsychotics and 61 treated with atypical antipsychotics) under naturalistic treatment conditions, and 50 healthy controls were given the following: Test of Everyday Attention, Facial Emotion Recognition Test, Facial Memory Recognition Test, and "Reading the mind in the eyes" Test.

Aim: The aim of our work was to assess qualitatively and quantatively emotional deficits in patients diagnosed with schizophrenia following ICD-10 criteria in early and late stages of the schizophrenic process and the evaluation of the relationship between genes polymorphism of enzymes influencing dopaminergic, serotoninergic, and noradrenergic transfer and emotional functioning of the examined patients.

Method: In our study the following methods have been used: Short Recognition Memory test for Faces (TPRT), Facial Expression Recognition Test (FERT), "Reading the mind in the eyes" Test and psychiatric scales (SAPS, SANS, BDI) and molecular techniques (PCR reaction, RFLP and VNTR techniques). 100 paranoid schizophrenia patients (43 female and 57 man) and 50 healthy controls (30 female and 20 man) were invited to participate in the study.

[Stress oxidative in schizophrenia].

Etiopathogenesis of schizophrenia development is unknown yet in 1% of human population. There is damaged metabolism of biological membranes, abused production of free radicals and altered activity of antioxidant enzymes in patients with schizophrenia. Recently, a study showed that many of the genes and proteins whose expression is modified in the schizophrenic brain are related to glutathione and oxidative stress pathways.

[Genetic polymorphism of a MAO in mental disorders].

Amin oxydase (monoaminoxydase, MAO) is an enzyme which catalyses chemical reactions of biogenic amines. It plays a crucial role in pathogenesis of mental disorders associated with the dysfunction of the central monoaminergic systems (schizophrenia, affective disorders, some forms of alcohol dependence, and personality disorders). MAO has got two isoforms such as MAO-A and MAO-B.

[Genetic polymorphism of COMT in mental disorders].

Many neurobiochemical studies show abnormalities within dopaminergic neuropathways, particularly altered dopamine transmission in etiopathogenesis of mental disorders. Evaluation of genes associated with the dopaminergic system include five well known subtypes of dopaminergic receptors, dopamine transporter and enzymes associated with the synthesis and degradation of dopamine, such as tyrosine hydroxylase, dopa decarboxylase, monoamine oxidase (MAO) and catechol O-methyltransferase (COMT). None of these genes is 'a' pathognomonic factor of schizophrenia onset.
