Therapeutic interventions in chronic mental illness face the important challenge to pursuit the quality of life (QOL) of patients. Insight into chronic mental illness, though a prerequisite for treatment adherence and a positive therapeutic outcome, has shown adverse associations with subjective QOL. This study aims to explore the contribution of psychopathological symptoms on the ambiguous role of insight on QOL. Seventy-two outpatients with schizophrenia spectrum disorders were ...

BACKGROUND: The frequent occurrence of obsessive-compulsive symptoms (OCS) in the course of schizophrenia and their impact on the functional outcome of the illness underlie the suggestion that the presence of OCS represents a separate subtype of schizophrenia, with a distinct clinical presentation and prognosis and specific neurobiological characteristics. This study investigated whether the presence of OCS in schizophrenia is associated with worse cognitive functioning in the domains of ...

BACKGROUND: Nowadays percutaneous endoscopic gastrostomy (PEG) is widely available, but patient-selection criteria and quality of informed consent are debated. The aims of this retrospective study were to evaluate the quality of information given to the decision-makers (relatives) and determine the overall acceptance of the procedure by the patients' family.

METHODS: The relatives of patients with PEG were interviewed by telephone, using a structured questionnaire. They (n = 55; 36% ...

The aim of this study was to evaluate the reliability and validity, as well as the specificity, of the Greek version of the Calgary Depression Scale for Schizophrenia (CDSS). Schizophrenic inpatients consecutively admitted at the Eginition Hospital, University of Athens, were included in the study. Patients were assessed on admission using the CDSS, the Hamilton Depression Rating Scale (HDRS), the Positive and Negative Syndrome Scale (PANSS), the Rating Scale for Extrapyramidal Side ...

BACKGROUND: Patients with psychosis have activation of the hypothalamic-pituitary-adrenal (HPA) axis during the acute phase of the psychosis. Whether this has any morphological consequences for the pituitary gland is currently unknown.

AIMS: To examine pituitary volume variation in people at different stages of psychotic disorder.

METHOD: Pituitary volume was measured using 1.5 mm, coronal magnetic resonance images in 24 people with first-episode psychosis, 51 with established ...

Relationships between Cloninger's temperament and character dimensions and plasma sex hormone levels and biogenic amine turnover were studied in male prison inmates convicted of rape (n=61) or child molestation (n=24) and normal male controls (n=25). The participants completed the Temperament and Character Inventory (TCI), which includes the temperament dimensions Novelty Seeking, Harm Avoidance, Reward Dependence and Persistence as well as the character dimensions Self-Directedness, ...

BACKGROUND: Our knowledge concerning immune functioning in bipolar affective disorder (BAD) is limited, while lithium's immunomodulatory effects seem multiple and conflicting. Our aim was to evaluate cytokine production and lithium's effect on it in BAD patients, using ELISPOT technique as a sensitive tool.

METHODS: Cytokine (IL-2, IL-6, IL-10 and IFN-gamma) production from isolated peripheral blood lymphocytes (PBLs) was evaluated (ELISPOT technique) in 40 euthymic BAD patients under ...

BACKGROUND: The aim of the current study is to investigate the relationship between physical anhedonia and psychopathological parameters, pharmacological parameters or motor side-effects in a sample of inpatients with schizophrenia in an acute episode of their illness.

METHOD: Eighty one patients with schizophrenia, consecutively admitted, with an acute episode of their illness, at the Eginition Hospital, Department of Psychiatry, University of Athens, during a one-year period were ...

Several scales have been used to diagnose and evaluate depression in schizophrenia. However, the association between different depression scales and between depression scales and negative symptoms has not been studied adequately. Sixty-four consecutively admitted schizophrenic patients to Eginition Hospital, Department of Psychiatry, Athens, were assessed on the following scales: the Calgary Depression Scale for Schizophrenia (CDSS), the Hamilton Depression Rating Scale (HDRS), the ...

Disaster research related to earthquakes has almost exclusively dealt with their long-term psychosocial impact; besides, diagnoses were previously based only on DSM criteria. Therefore, it is pertinent to assess stress-related reactions of earthquake victims during the early post-disaster period through the application of ICD-10 criteria. For the first 3 weeks following an earthquake, 102 help-seekers were assessed based on a checklist of sociodemographic variables and a semi-structured ...

Psychotic depression is a clinical subtype of major depressive disorder in the recent editions of the psychiatric diagnostic systems ICD-10 (1992) and DSM-IV (1994). Recent evidence suggests that psychotic depressed patients are more impaired on neuropsychologic tests measuring attention as compared to nonpsychotic depressed patients. However, information on this issue between psychotic and nonpsychotic depression is limited. It has become clear that attention is not a single concept; ...

Risperidone is a novel and atypical agent with a dual antagonistic effect on 5-HT and D receptors. Open-label reports and one controlled study suggest that risperidone addition is effective in patients with obsessive-compulsive disorder refractory to treatment with serotonin reuptake inhibitors. However, risperidone has also been implicated in the production or exacerbation of obsessive-compulsive symptoms. We report six cases (schizophrenia, five cases; psychotic depression, one case) ...

OBJECTIVE: Schizophrenia has been associated with a high rate of suicide. This study investigates the prevalence of suicidal ideation in a population of inpatients with acute schizophrenia, together with the clinical parameters associated with suicidal thoughts.

METHOD: We assessed 93 schizophrenia patients. We matched subjects for age and sex and compared subjects with and without suicidal thoughts. We performed stepwise multiple regression analysis to assess the association between ...
