A study of acculturation in psychotic and non-psychotic immigrants living in Athens.

BACKGROUND: Acculturation is the phenomenon that results when a group with one culture comes into continuous contact with a host culture. AIMS: To investigate the correlation between acculturation and psychotic symptomatology in a group of immigrants suffering from psychosis and to explore differences in demographic factors related with the acculturation process between individuals with and without psychosis. METHODS: Sixty-five patients and 317 non-psychotic immigrants were interviewed using the Immigrant Acculturation Scale (IAS) and a structured questionnaire for demographic data. The Positive and Negative Syndrome Scale (PANSS), the Calgary Depression Scale for Schizophrenia (CDSS) and the Global Assessment of Functioning (GAF) were also administered to all immigrants suffering from psychosis. RESULTS: Total IAS scores, as well as IAS everyday life scores, were positively correlated with GAF scores. IAS everyday life score in the patient group related with religion, marital status, gender and years in Greece, while in the non-psychosis group it was related with gender and years in Greece. IAS wishful orientation/nostos (the strong desire for one's homeland) related with religion in both groups. The IAS identity in the psychosis group did not show any significant relation with any of the variables, while in the non-patient group, it was related with marital status, gender and years in Greece. Age, duration of residence in Greece and higher adoption of Greek ethnic identity were the variables that differentiated the two groups of immigrants. CONCLUSION: Acculturation in immigrants suffering from psychosis could be seen as a process that does not correlate strongly with the severity of the symptomatology but is probably influenced by different set of factors.

Fatigue in female patients with major depression: the effect of comorbid anxiety disorders.

Several studies have investigated fatigue in the general population, in primary care facilities as well as in patients with fatigue-related physical diseases, but only marginally in patients with Major Depressive Disorder (MDD). Therefore, the investigation of correlates of depression-related fatigue is highly warranted and expected to facilitate the implementation of effective fatigue-specific treatment strategies. Depressed patients often suffer from comorbid anxiety disorders (CADs) or subthreshold anxiety symptoms. This study aimed to investigate the independent correlation of the severity of fatigue in female patients with MDD with the presence, number and type of CADs. We studied 70 consecutive female MDD patients (48.6% inpatients), aged 23-65 years (mean 48.2±10.6 years), currently in a Major Depressive Episode [17-item Hamilton Depression Rating Scale (HDRS) score≥17] and free of other fatigue-associated conditions. Diagnostic assessments were made with the short structured DSM-IV-based MINI version 5.0.0. Reported fatigue was assessed with the 14-item Chalder Fatigue Questionnaire (FQ). Correlations between the FQ score and age, inpatient status, HDRS score, presence and number of CADs were calculated. Then, stepwise multiple regression analyses were performed, with the FQ score as the dependent variable,so as to isolate independent predictors of the severity of fatigue. 92.9% of patients had clinically significant fatigue. 62.9% were suffering from at least one CAD (38.6% met criteria for one CAD,21.4% for two and 2.9% for three). 51.4% were diagnosed with generalized anxiety disorder (GAD),25.7% with panic disorder and/or agoraphobia (PD/AP), 17.1% with social anxiety disorder and 7.1%with obsessive-compulsive disorder. The FQ score was significantly correlated with the HDRS score(r=0.406, p<0.001), the presence of any CAD(s) (rho=0.4, p=0.001), the number of CADs (rho=0.393,p=0.001), the presence of GAD (rho=0.421, p<0.001) and the presence of PD/AP (rho=0.252, p=0.035).In multiple regression analyses, the presence and number of CADs and the presence of comorbid GAD turned out as significant independent predictors of the FQ score along with the HDRS score.The severity of fatigue in female MDD patients is independently correlated with the presence and number of CADs and, in specific, comorbid GAD. Our findings imply that: (1) this effect might in part account for greater impairment/disability and adverse prognosis for MDD with CADs; (2) high levels of fatigue, putatively clustering with anxiety symptoms, may be a marker of severity and anxiety disorders comorbidity for MDD and may define an "anxious-fatigued" subtype/phenotype in this population; (3) medications and psychotherapies for the management of severe depression-related fatigue should also target CADs.

Seasonality, suicidality and melatonin.

Seasonality of suicidal behavior has been investigated regarding both neurobiological and climatic factors, as well as psychopathological and social aspects. Most of the studies detectedpeaks in late spring and troughs in the winter. Several lines of evidence evaluated the role of extended periods of light associated with probability of suicides whereas others summarize the alterations of melatonin excretion and its seasonal variation along with seasonaldistribution of psychiatric disorders. The purpose of this paper is to provide an overview of studies attempted to reach an explanatory model of underlying pathophysiology of melatonin in thepathogenesis of seasonal variation in suicidality. There is argument on the interconnection between suicide rates and weather factors. However, an inverse pattern of melatonin levels and the seasonalpeak in suicides was observed. These findings suggest that sunlight exposure along with a wide spectrum of other factors may explain the aetiopathogenesis of suicidal behavior.

Attitudes on euthanasia and physician-assisted suicide among medical students in Athens.

Attitudes towards assisted death activities among medical students, the future health gatekeepers, are scarce and controversial. The aims of this study were to explore attitudes on euthanasia and physician-assisted suicide among final year medical students in Athens, to investigate potential differences in attitudes between male and female medical students and to review worldwide attitudes of medical students regarding assisted death activities. A 20- item questionnaire was used. The total number of participants was 251 (mean age 24.7±1.8 years). 52.0% and 69.7% of the respondents were for the acceptance of euthanasia and physician-assisted suicide, respectively. Women's attitudes were more often influenced by religious convictions as well as by the fact that there is a risk that physician-assisted suicide might be misused with certain disadvantaged groups. On the other hand, men more often believed that a request for physician-assisted suicide from a terminally ill patient is prima-facie evidence of a mental disorder, usually depression. Concerning attitudes towards euthanasia among medical students in various countries there are contradictory results. In USA, the Netherlands, Hungary and Switzerland most of the students supported euthanasia and physician-assisted suicide. However, in many other countries such as Norway, Sweden, Yugoslavia, Italy, Germany, Sudan, Malaysia and Puerto Rico most students expressed negative positions regarding euthanasia and physician assisted suicide.

Fatigue and somatic anxiety in patients with major depression.

The objective this study aimed to investigate the independent contribution of somatic anxiety to the severity of depression-related fatigue. Seventy-six patients (85.5% female), aged 23-65 years (mean 48.7±10.6), diagnosed with major depressive disorder and currently in a major depressive episode (ΜΙΝΙ 5.0.0.) with a 17-item Hamilton Depression Rating Scale (HDRS) score ≥17, were studied. Forty-nine patients (64.5%) were concurrently suf fering from anxiety disorder(s). Patients with physical diseases or other fatigue-related conditions were excluded. Reported fatigue was measured with the 14-item Fatigue Questionnaire (FQ). Based on HDRS item 11 (somatic anxiety) scores, patients were divided into those with somatic anxiety (HDRS-11≥2) and those without (HDRS-11≤1). Pearson's (r) and Spearman's (rho) correlations between FQ score, age, gender, inpatient status, HDRS score and somatic anxiety status were calculated. A multiple regression analysis was then performed, with FQ as the dependent variable. Fifty-seven patients (75%) were rated as suffering from somatic anxiety (HDRS-11≥2). Patients with somatic anxiety had significantly higher HDRS and FQ scores. The FQ score significantly correlated with the HDRS score (r=0.36, p=0.001) and somatic anxiety status (rho=0.35, p=0.002). The FQ score was independently predicted by HDRS score and somatic anxiety status, with standardised beta coefficients of 0.259 (p=0.028) and 0.255 (p=0.031), respectively. R2 was 0.185. Both the severity of depression and the presence of somatic anxiety independently correlate with the severity of reported fatigue in patients with major depression. This finding has potential implications for the management of depression-related fatigue.

Clinical symptoms and social functioning among immigrant and greek patients with schizophrenia: A comparative study.

Migration is considered an important risk factor for schizophrenia. However, studies on the differences in psychotic symptomatology between immigrants and native patients revealed mixed results. This study compared clinical symptoms and social functioning between immigrant and native patients with schizophrenia in Greece in order to examine the influence of social factors on the disorder's manifestation and severity. A structured questionnaire including demographic and clinical information was administered to two groups of patients with schizophrenia; the first one was comprised of 65 immigrant patients (38 men and 27 women) and the second included 58 greek patients (35 men and 23 women). Patients' psychopathology was evaluated by the Positive and Negative Syndrome Scale (PANSS), the Calgary Depression Scale for Schizophrenia (CDSS) and the Global Assessment of Functioning Scale (GAF). The x2 test and the ANOVA were used for the comparisons of categorical and continuous variables respectively between the two groups of patients. Analysis of eigenvalues and multivariate analysis (MANOVA) were also used. Age and duration of illness were significant greater in the greek group of patients. Lack of insight was the only reason of hospitalization of immigrant patients. The immigrant group of patients had significantly lower scores in the negative syndrome subscale, the general psychopathology subscale and the total PANSS scale while they had significantly higher scores in the GAF scale. No between patients' groups difference was found on CDSS scores. Analysis of eigenvalues and MANOVA revealed that the national group (immigrants vs native) and the reason of admission were the only general variables with significant influence on patients' psychopathological features and functioning. Consistently with previous studies that have shown better prognosis in immigrant compared to the native patients with schizophrenia, immigrant patients in our study had milder negative and total psychotic symptomatology and were less impaired in terms of global functioning than the greek group. Being an immigrant appears to be an important factor related to these differences between our study groups. A possible explanation of our findings could be that immigrant patients with schizophrenia attending to greek mental health services have been 'filtered'because of a 'salmon bias' type phenomenon; the severe ill usually return to their country of birth due to the lack of financial and social support for immigrant patients in Greece. An alternative hypothesis is that the families and the local communities of immigrant patients with schizophrenia, being tied enough, provide support to their ill members that results in better outcome, especially with respect to negative syndrome and social functioning.

Switching to amisulpride monotherapy for treatment-resistant schizophrenia.

The objective of this study was to assess switching to amisulpride (AMS) in treatment-resistant schizophrenia. Seven male subjects were switched to AMS and followed for 8 weeks. PANSS scores improved from 123 to 66 over this period. We conclude that AMS is of interest in the treatment of refractory schizophrenia.

Impaired P600 in neuroleptic naive patients with first-episode schizophrenia.

Deficits of working memory (WM) are recognized as an important pathological feature in schizophrenia. Since the P600 component of event related potentials has been hypothesized that represents aspects of second-pass parsing processes of information processing, and is related to WM, the present study focuses on P600 elicited during a WM test in drug-naive first-episode schizophrenics (FES) compared to healthy controls. We examined 16 drug-naive first-episode schizophrenic patients and 23 healthy controls matched for age and sex. Compared with controls schizophrenic patients showed reduced P600 amplitude on left temporoparietal region and increased P600 amplitude on left occipital region. With regard to the latency, the patients exhibited significantly prolongation on right temporoparietal region. The obtained pattern of differences classified correctly 89.20% of patients. Memory performance of patients was also significantly impaired relative to controls. Our results suggest that second-pass parsing process of information processing, as indexed by P600, elicited during a WM test, is impaired in FES. Moreover, these findings lend support to the view that the auditory WM in schizophrenia involves or affects a circuitry including temporoparietal and occipital brain areas.

Prevalence and characteristics of patients with pseudoakathisia.

Pseudoakathisia (PsA) is characterised by the typical motor features of akathisia but there is a lack of subjective awareness. A total of 153 in-patients on neuroleptic medication hospitalized in two representative wards of the Psychiatric Hospital of Attica in Athens were rated on the census date using the Rating Scale for Drug-Induced Akathisia [Barnes, Br. J. Psychiatry, 154 (1989) 672-676], the Rating Scale for Extrapyramidal Side-Effects [Simpson and Angus, Acta Psychiatr. Scand. 212 (Suppl.) (1970) 11-19] and the Abnormal Involuntary Movements Scale [US Department of Health, Education and Welfare, ECDEU Assessment Manual (1976) pp. 534-537]. Eight subjects of the total in-patient population were found to have PsA of chronic type (point prevalence 5.23%). The point-prevalence of PsA among schizophrenic patients was 4.76%. In addition to the diagnosis of chronic pseudoakathisia, five patients (62.5%) had a concurrent diagnosis of chronic parkinsonism. Among patients with PsA, significant correlations were found between parkinsonism score and current daily dose of neuroleptics or high potency neuroleptics. There is evidence of a relationship between chronic pseudoakathisia, chronic parkinsonism and daily dose of neuroleptic.

Comparison of four scales measuring depression in schizophrenic inpatients.

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 Expanded Brief Psychiatric Rating Scale-Depression subscale (EBPRS-D), the Positive and Negative Syndrome Scale-Depression subscale (PANSS-D) and the Negative Symptoms subscale (PANSS-N). The depression scales were found to be highly intercorrelated with the exception of the comparison between the EBPRS-D and the PANSS-D. Out of the four depression scales studied, only CDSS and EBPRS-D can discriminate between depression and a PANSS-Negative Symptoms subscale score or negative item scores.

The Greek version of the calgary depression scale for schizophrenia.

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 Effects (RSESE), the Rating Scale for Drug-Induced Akathisia (RSDIA) and the Abnormal Involuntary Movement Scale (AIMS). The CDSS was found to have a high inter-rater reliability, as well as test-retest reliability or split-half reliability. The internal consistency of the CDSS was good (a=0.87). There were positive correlations between the CDSS and the HDRS, or the depression cluster of the PANSS. The mean score on the CDSS showed no significant correlations with that of the PANSS negative subscale (r=0.123); a negative but not significant correlation with that of the PANSS positive subscale (r=-0.036); a weak correlation with that of the PANSS general psychopathology subscale (r=0.218); and no significant correlations with that of the RSESE (r=0.197), the RSDIA (r=0.160) or the AIMS (r=0.031). Our results give further support to the reliability, the validity, and the specificity of the CDSS.

Treatment of a mild form of neuroleptic malignant syndrome with oral diazepam.

A mild form of neuroleptic malignant syndrome (NMS) in a schizophrenic patient who was receiving a depot neuroleptic is described and beneficial response to oral diazepam 50 mg daily is reported.

Attempted suicide in psychiatric outpatients with concurrent physical illness.

Fifty outpatients with concurrent psychiatric and physical illness who were referred following a suicidal attempt to the Outpatient Psychiatric Department, University of Athens, during a period of 3 years (1979-1981) were compared with a random sample of 85 psychiatric outpatients without concurrent physical illness who had attempted suicide at the same time period. Attempters suffering from both mental and physical illness were more often of an older age, married, pensioners or housewifes, were living with their own family, were suffering from organic psychotic condition or major affective disorder (depressive type) and more frequently used violent methods for attempting suicide. Among attempters the commonest physical illnesses were neurological diseases (40%), cardiovascular diseases (26%) and cancer (10%).
