Comorbidity of dsm-iii-r personality disorders in schizophrenic and unipolar mood disorders: a comparative study

We investigated the overall prevalence and the differential comorbidity of Diagnostic and Statistical Manual (DSM)-III-R personality disorders in 166 remitted or recovered patients with schizophrenic (n = 102) or unipolar mood disorder (n = 64). Over 60% of both patient groups met the DSM-III-R criteria of at least one DSM-III-R personality disorder as assessed by means of the Structured Clinical Interview for DSM-III-R (SCID-II-R), receiving on average 3.1 personality diagnoses. Neither DSM-III-R categories of personality disorders, nor scores on its three clusters A, B and C, nor total score on SCID-II-R differed significantly across the two groups. In conclusion, DSM-III-R personality disorders, although highly prevalent in schizophrenic and unipolar mood disorders, lack any specificity with respect to these categories of mental disorders.

Mental health law in Greece

Like all European countries, Greece has developed its national legislation based on the principles of equality and the right of representation, but there is no separate, specific mental health law in Greece. This paper describes the law for involuntary psychiatric admission. The law concerning criminal and civil responsibility and the law relating to individuals with addictions committing drug-related crimes are also outlined.

[Greek students' attitudes towards mental disorders]

Attitudes and beliefs of the population regarding the mentally ill have been universally subject of many researches. Research of different groups' opinion for mental disorders has given remarkable findings that assist in the right design of psychiatric services. Objective of this thesis is to study the attitude of students towards mental illness. In particular, it intends to study the differences derived from the age, gender, place of birth, kind of studies, year of study, duration of stay at the place of studies and the existence of mental disorders in the student's family. Data were collected from 536 students randomly selected from Universities and Technological Institutions both in Athens and Thessaloniki. In general, the participants are being divided based on the subject of their studies in undergraduates of human sciences, exact sciences, social and health sciences. The short version of the scale "Community Attitudes Toward the Mentality III" (CAMI) was used, which consists of 26 questions sorted to four subscales (domination scale, humanism scale, social exclusion scale and the scale measuring the community beliefs regarding the care of mentally ill), along with a special questionnaire in order to collect social and demographic data. Students' attitudes towards mental illness are influenced by demographic factors, the department they are studying at and the year of study. Female gender (p=0.000), personal contact with mentally ill (p=0.012), studying in Universities (p=0.031) and especially social sciences (p=0.009) are associated with positive attitudes. On the contrary, less years of studying are associated with negative attitudes whereas older students appear to score less in the Domination Scale (p=0.000). It is significant that the place of birth (p=0,335) and the duration of stay at the place of studies (r=0.735) did not show any association with the variables studied in this research. However these results cannot be compared with older researches since there are not sufficient findings. Women tend to show more humanitarian attitude towards the mentally ill in comparison to men, emphasizing the role the community plays in their support reinforcing their reintegration in the community verifying the results of research conducted in Greece and other countries. Furthermore, students who have previously been in contact with mentally ill tend to have more favorable attitude and understanding towards them. The findings concerning the age and the years of studying highlight the imperative need of exploring thoroughly the knowledge regarding the attitudes towards mental illness.

[Forensic psychiatry and Islamic law]

Islam is the second most popular monotheistic religion in the world. Its followers, the Muslims, are about 1.2 billion people and are the majority in 56 countries around the globe. Islam is an holistic way and model of life and its rules, according to a large proportion of Muslims, should have more power than the laws deriving from any secular authority. This means that the divine laws, as depicted from Islam's holy scripts, should be the laws of the land. In the strict Islamic states, as Saudi Arabia, the Islamic law or the Shari'ah prevails. Shari'ah means the path, the road each faithful Muslim should follow according to the rules of God. The Islamic views on mental health have some interesting characteristics: on the one hand, the moral necessity for the protection and care of the vulnerable individuals is very strong, but on the other hand superstitions and stigmatization influence the peoples' attitude against mental health patients. At the beginning of its historical course, Islamic world was a pioneer concerning mental health care. Unfortunately, as time passed by, we have observed considerable regression. In our days mental health services provided in most of the Islamic states cannot be considered adequate according to modern Western standards. The same course characterizes the Forensic Psychiatric services and the relevant legislation in the Islamic world.

Suicide and seasonality

OBJECTIVE

  Seasonal variation of deaths by suicide offers an important pathway in the study of possible suicide determinants of suicide and consequently suicide prevention.

METHOD

  We conducted a review of the literature on suicide seasonality, assessing articles published between 1979 and 2009.

RESULTS

  The majority of the studies confirm a peak in spring, mainly for men, older individuals, and violent methods of suicide. A secondary peak during autumn is observed. There is no common seasonality pattern for suicide methods. However, there are also certain studies that did not confirm seasonal variation. Inconsistent results with reduced, unchanged, and even increased suicide seasonality have been reported. Aspects on the association between seasonality and suicides are discussed. Except sex, age, and method of suicide, other parameters were taken into account to find more specific characteristics of seasonality in suicides as well. The influence of clinical, bioclimatic, sociodemographic as well as biological factors seems to affect the seasonal variation.

CONCLUSION

  Studies from both the Northern and the Southern hemisphere report a seasonal pattern for suicides. These studies are not only an important source of epidemiological data for suicides but also represent a global effort to uncover hidden parameters of this self-destructive behaviour.

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.

Anxiety disorders and obesity

Anxiety disorders are the most prevalent mental disorders in developed countries. On the other hand, obesity is recognized to be one of the greatest public health problems worldwide.The connection between body weight and mental disorders remains an open issue. Low body weight has been studied enough (anorexia nervosa is a typical example) but high body weight has not been addressed sufficiently. It is known that obesity has been related with depression. Although moderate level of evidence exists for a positive association between obesity and anxiety disorders, the exact association between these two conditions is not clear yet.The studies about this subject are quite few and they follow different methodology. Furthermore,anxiety disorders share some common elements such as anxiety, avoidance and chronicity, but they also present a great deal of differences in phenomenology, neurobiology, treatment response and prognosis. This factor makes general conclusions difficult to be drawn. Obesity has been associated with anxiety disorders as following: most of the studies show a positive relationship with panic disorder, mainly in women, with specific phobia and social phobia. Some authors have found a relationship with generalised anxiety disorder but a negative relationship has been also reported.Only few studies have found association between obesity and agoraphobia, panic attacks and posttraumatic stress disorder. There has not been reported a relationship between obesity and obsessive-compulsive disorder. The causal relationship from obesity to anxiety disorders and vice versa is still under investigation. Pharmacological factors used for obesity treatment, such as rimonabant,were associated with depression and anxiety. Questions still remain regarding the role of obesity severity and subtypes of anxiety disorders. Besides, it is well known that in the morbidly obese patients before undergoing surgical treatment, unusual prevalence of psychopathology, namely depression and anxiety disorders, is observed. Anxiety is also a common trait in personality disorders.There is no single personality type characteristic of the morbidly obese, they differ from the general population as their self-esteem and impulse control is lower. Obese patients present with passive-dependent and passive-aggressive personality traits, as well as a trend for somatization and problem denial. Their thinking is usually dichotomous and catastrophic. Obese patients also show low cooperativeness and fail to see the self as autonomous and integrated. When trying to participate in society roles they are subject to prejudice and discrimination and should be treated with concern to help alleviate their feelings of rejection and guilt.

Association of serum BDNF levels with hippocampal volumes in first psychotic episode drug-naive schizophrenic patients

Evidence suggests that hippocampal volumetric abnormalities are present in first-episode schizophrenia. The hippocampus contains the highest brain levels of neurotrophic factors, which are major determinants of neuronal plasticity. Brain-derived neurotrophic factor (BDNF) influences neuronal survival, differentiation, synaptogenesis, and maintenance and is also correlated with neuronal activation in the hippocampus. BDNF is also involved in the development and modulation of dopaminergic-related systems. Alterations of serum BDNF levels have been shown in a number of studies with first episode patients with schizophrenia, probably reflecting an association between BDNF and the pathogenesis of the disorder. In the present study we investigated the correlation between serum BDNF levels and hippocampal volumes in a sample of first episode drug-naïve patients with schizophrenia (FEP) and healthy control subjects. We found that hippocampal volume (HV) was decreased in FEP patients. Corrected right HV of FEP patients were significantly smaller compared to corrected right HVs of healthy subjects. The serum BDNF levels in the sample of FEP patients was significantly reduced compared to the healthy subjects. A significant positive association was found between serum BDNF and the corrected right HV in the group of patients such that the smaller the HV, the more reduced the serum BDNF levels. (Pearson r=0.452, p=0.045). Our findings indicate that low serum BDNF levels are associated with reduction in HV at the onset of schizophrenia and may further support the theory of a neuroprogressive-neurotoxic reaction associated with the onset of psychosis.

Prolactin and cortisol responses to acute intravenous clomipramine challenge in patients with mania, depression and healthy controls: evidence for reduced serotonergic responsivity

Serotonergic dysregulation has been shown to be involved in the pathophysiology of unipolar and bipolar depression. Neuroendocrine challenge tests have been extensively used to investigate serotonin functioning in the brain. Although the role of serotonin has received a great deal of attention using neuroendocrine challenge paradigms, little effort has been made to explore the role of serotonin in mania. We assessed serotonergic neuroendocrine responsivity in patients with depression (n = 22), mania (n = 11) and 15 healthy controls by measuring the prolactin (PRL) and cortisol responses to i.v. clomipramine (CMI) and searched for possible differences among the groups. Blunted PRL responses to CMI in manic and depressed patients compared to healthy controls were found. The response to CMI disclosed similar results for the 2 patient groups. No significant differences were found among the 3 subject groups in the cortisol response to CMI. The blunted PRL responses to CMI in patients with mania and depression suggest that serotonergic functioning in mania and depression is similarly impaired, at least at the level of hypothalamus-hypophysis.

[Psychotherapeutic interventions in stereotypies]

Stereotypies belong to the psychomotor disorders and they are found in many different disorders. This article refers to the international literature about the psychotherapeutic interventions in stereotypies and reviews the psychotherapeutic techniques that are already being used for these disorders. This study refers to four kinds of psychotherapeutic treatment: (a) Behavioral therapy, (b) Milieu therapy which can be combined successfully with an occupational therapy, (c) Family therapy and (d) Supportive or cognitive or dynamic psychotherapy. The method used for finding the articles for this review was the web research. The articles found were 44 in total, but only 25 were studied extensively since they were absolutely relative to the subject of this review. 12 of these articles were case studies, 7 theoretical papers and 5 of them were reviews. The last one was a research epidemiological study. According to most of the articles, behavioral therapy is considered to be the most effective psychotherapeutic treatment for attenuating stereotypies and relies on techniques like systematic desensitization, environmental enrichment, positive reinforcement of alternative behaviors and negative reinforcement of the "problematic" behaviors. The milieu therapy, combined with occupational therapy, endeavours to shape an appropriate environment where the patient can recover. Family therapy focuses on fully informing the relatives about the nature of stereotypies. Supportive psychotherapy focuses on the current problems in the patient's life. The cognitive psychotherapy tries to fix the dysfunctional thoughts of the patients. Finally, the dynamic psychotherapy is focused on the restoration or reinforcement of the patient's defensive mechanisms. It should be noted that there is a lack of systematic research in the field of stereotypies in general and, especially, regarding psychotherapeutic interventions.

[A volumetric study of brain structures in subtypes of depression]

The aim of this study is to compare the volumes of hippocampus, amygdala and subgenual prefrontal cortex among patients with melancholic depression, patients with psychotic depression and normal controls. Thirty nine patients with a diagnosis of major depression (22 with melancholic and 17 with psychotic subtype) and 18 normal controls were included in the study. Hippocampal, amygdala, anterior and posterior subgenual cortex volumes were measured by manual tracings on magnetic resonance volumetric images and compared across the 3 groups. We identified larger amygdala volumes and smaller left anterior subgenual cortex volumes in both patient groups compared to controls. There were no differences in hippocampal, right anterior and posterior subgenual cortex volumes across the 3 groups. In conclusion, melancholic and psychotic depression were not differentiated regarding the volumes of the hippocampus, the amygdala, and anterior and posterior subgenual cortex, even though amygdala volumes and left anterior subgenual cortex volume of both patient groups were differentiated compared to controls.

Tardive dyskinesia induced by quetiapine and confirmed by a Dat-scan

Background

Tardive dyskinesia is a serious side effect of antipsychotics’ activity. Imaging of the dopamine transporter could demonstrate the possible involvement of dopaminergic pathway in the appearance of tardive dyskinesia.

Methods/results

We report a case with paranoid schizophrenia and tardive dyskinesia symptoms. A first trial with quetiapine improved TD symptoms while an increase of its dose after a relapse of the underlying disease deteriorated the TD symptoms. Following that, sertindole was initiated which led to improvement of both psychotic and TD symptoms. A DAT scan showed physiologic distribution in the basal ganglia. Six months later after a serious cardiac syncope, sertindole was discontinued. Quetiapine was then started which led again to TD symptoms. A second DAT scan showed decreased dopamine transporter uptake in the area of basal ganglia.

Conclusion

We conclude that decreased dopamine transporter uptake seemed to associate with the deterioration of TD.

Normal 0 14 general punitiveness and direction of hostility in chronic prostatitis patients

Introduction

Chronic prostatitis has been long considered a psychosomatic illness. We have previously studied alexithymic and obsessive-compulsive features in chronic prostatitis patients.

Aims

To evaluate introverted, extroverted and total hostility in patients with chronic prostatitis.

Methods

Patients diagnosed with chronic prostatitis at a tertiary care ID clinic were evaluated with the Hostility and Direction of Hostility Questionnaire (HDHQ), a questionnaire with 5 subscales designed to assess total hostility or punitiveness and direction of hostility. Patients were categorized according to the NIH Consensus Classification System for Prostatitis Category and the NIH Chronic Prostatitis Symptom Index (CPSI) was calculated.

Results

82 patients (median age 37.5 yrs old; IQR 30-45.5 yrs) were evaluated. According to the NIH Prostatitis Classification patients were categorized as type II: 45.1%, IIIa: 9.7%, IIIb: 39%, IV: 2.4%. Median CPSI score was 19.5 (IQR: 14.5-24.3). Median introverted, extroverted and total hostility scores were 3 (IQR: 2-6), 9 (IQR: 7-13) and 13 (IQR: 9-18) respectively. Results from the Extroverted Hostility HDHQ subscale correlated (r squared = −0.25, p = 0.024) with subscales of the TAS (Toronto Alexithymia Scale). These results were independent of CPSI scores.

Conclusions

Chronic prostatitis patients’ total hostility scores are similar to those of the general population reported by other studies. However, chronic prostatiitis patients show more outward directed hostility. The relationship between TAS subscale scores and measures of extroverted hostility needs further elucidation. Patients with chronic prostatitis are potentially at risk for psychiatric disturbances and thus may need psychiatric counseling and therapy.

[Behavioral and psychological symptoms of dementia and their management]

The decline in cognitive function is a core feature of dementias. However, other symptoms of the disease are also crucial. These symptoms are the behavioral and psychological manifestations of dementia and include symptoms such as delusions, hallucinations, delusional misindentification syndromes (DMS), illusions, anxiety, aggression, depression, personality changes, disinhibition-impulsivity, violation of social and moral norms, changes in dietary or eating behavior and repetitive behaviors. Delusions, hallucinations, anxiety, depression and aggression are highly prevalent in Alzheimer's disease, vascular dementia and dementia with Lewy bodies, whereas symptoms that include severe disturbance of behavior are highly prevalent in frontotemporal dementias. Psychotic symptoms are associated with subcortical disturbances mainly of the limbic system. Patients with depression present greater loss of noradrenergic cells in the locus coeruleus and loss of serotonergic nuclei of dorsal raphe. Furthermore, disturbances of behavior are associated with frontal lobe dysfunction. Atypical antipsychotics is the first treatment option for delusions, hallucinations, misidentifications, anxiety and aggression. Furthermore, antidepressants may be useful for moderate or severe depression as well as for disinhibition-impulsivity, aggression, changes in dietary or eating behavior and repetitive behaviors. Cholinesterase inhibitors may also improve apathy, anxiety, disinhibition, aberrant behavior, mood disorders and hallucinations. Moreover, non-pharmacological methods alone or in combination with psychotropic drugs may also improve patient's symptomatology.

Association of serum brain-derived neurotrophic factor and duration of untreated psychosis in first-episode patients with schizophrenia

BACKGROUND/AIMS

The brain-derived neurotrophic factor (BDNF) levels in serum and the central nervous system are altered in patients with schizophrenia, suggesting that changes in the expression of BDNF might contribute to the disease pathophysiology. Long duration of untreated psychosis (DUP) has been associated with poorer prognosis in patients with schizophrenia. Such a relationship of untreated psychosis to outcome may indicate a neurodegenerative process and may have important implications for understanding the pathophysiology of schizophrenia.

METHODS

In this study, we investigated the association between serum BDNF levels and DUP in a sample of drug-naïve patients in their first episode of schizophrenia (FEP). We investigated serum BDNF levels in a sample of 37 drug-naïve FEP patients and 21 matched healthy subjects.

RESULTS

The serum BDNF level in the sample of FEP was significantly reduced compared to the healthy subjects (18.87 +/- 8.23 vs. 29.2 +/- 7.73 ng/ml, t = 4.76, d.f. = 57, p = 0.01). A negative correlation was found between serum BDNF levels and DUP in the group of patients (r = -0.346, p = 0.036).

CONCLUSIONS

Our findings indicate that low serum BDNF levels at the onset of schizophrenia were associated with a long DUP and this could reflect an acute neurodegenerative reaction during the untreated phase of psychosis.

Hospital anxiety and depression scale. A quantitative analysis in medical outpatients, psychiatric outpatients and normal subjects

Depressive and anxiety symptomatology represent the most common psychiatric manifestations that complicate the management and prognosis of patients with somatic disorders. The Hospital Anxiety and Depression Scale (HADS) is a reliable, valid andpractical screening tool for identifying and quantifying anxiety and/or depression in non-psychiatric out patients. The aim of the present study was to compare the psychometric properties of the HADS among internal medicine outpatients, psychiatric outpatients and the generalpopulation. The present study involved 264 subjects: 95 internal medicine outpatients, 79 psychiatric outpatients and 90 normal controls. Psychiatric outpatients were diagnosed according to DSMIV-TR and inclusion criteria required the absence of any psychotic or organic psychiatric disorder. Patients with depressive disorders were divided in 3 groups: major depression, dysthymic disorderand adjustment disorder with mixed anxiety and depressed mood. All patients were administered the following psychometric tools: HADS, BDI and STAI. Subjects of the control group were administeredonly HADS. In all psychometric scales the psychiatric group presented significantly greater values than the internal medicine and the control group. In turn, the internal medicine group scoredsignificantly higher than the control group. Within the psychiatric outpatient group significantly higher HADS and HADS-D scores were observed in the major depression group followed by the dysthymicdisorder and the adjustment disorder with mixed anxiety and depressed mood group. HADS may be capable of identifying anxiety and depressive symptoms between psychiatric outpatients, internal medicine outpatients and subjects in the general population. In addition, the HADS-D subscaledifferentiates the main depressive disorders.

Signs of striatal dopamine transporter density increase in association with improvement of tardive dyskinesia in a patient with schizophrenia, as demonstrated by a DAT scan

The imaging of the dopamine transporter could demonstrate the implication of dopaminergic pathway in the appearance of tardive dyskinesia. We report a case with psychotic and tardive dyskinesia symptoms. A DAT scan showed decreased dopamine transporter uptake in the area of brain's basal gaglia. A trial with quetiapine improved both psychotic and TD symptoms while a second DAT scan showed improvement status. We conclude that increased dopamine transporter uptake seemed to associate with the improvement of TD.

Association of serum BDNF and val66met polymorphism of the brain-derived neurotrophic factor in a sample of first psychotic episode patients

Polymorphisms in the brain-derived neurotrophic factor (BDNF) gene have been indicated to be associated with schizophrenia. Previous studies have suggested that val66met polymorphism may increase the risk for schizophrenia, although other studies have not confirmed this association. Decreased BDNF levels in the brain and the serum of patients with psychotic disorders have been reported in first episode psychotic (FEP) patients. In our study we investigated the potential genetic association of this polymorphism with schizophrenia in a sample of 38 FEP patients with schizophrenia compared with a sample of 21 normal controls. Furthermore, we assessed serum BDNF levels and investigated whether there was an association between this polymorphism and alterations of serum BDNF levels between the investigated groups. There was a significant difference in genotyped frequencies between cases and controls (p=0.030). The homozygous carriers Met/Met were over-represented in the schizophrenia group (13/31, 41.9%), compared to controls (2/19, 10.5%). The serum BDNF levels in the sample of FEP patients was significantly reduced compared to controls (18.87±8.23 ng/mL vs 29.2±7.73ng/mL, U=140, p=0.0). No association was found between alterations of serum BDNF levels and Val66Met polymorphism in the group of patients (p=0.198). Negative correlations were shown between serum BDNF levels of the patients and the PANSS Negative subscale scores (p=0.015). There was found no significant difference between genotypes and memory scores in the sample of patients. Our findings indicate that serum BDNF levels at the onset of schizophrenia and BDNF Val66Met variant may be susceptibility risk factors for schizophrenia.

Seasonality of violent suicides in the Athens greater area

The aim of the study was to ascertain suicide seasonality in the Greek population and to associate this seasonal variation with age, sex, and suicide method. Studying seasonality can be of help in establishing a public health policy, related with suicide prevention. This is an epidemiologic study based on forensic evidence. We studied the deaths caused by self-injury (trauma), namely deaths by violent suicide (not self-poisoning). Statistically significant suicide seasonality was established with a peak in May. This seasonal variation is attributed mainly to males. As for the method, suicide by hanging peaks in June and by shooting in April. It was also observed that seasonality for individuals above the age of 45 peaks in early May.

Dimensional Approach to Delusional Beliefs in Psychotic Depression in Old Age: Factor Structure and Clinical Correlates

Objective:

The present study attempted to investigate the clinically important broader dimensions of clinical characteristics of delusions, through multivariate analysis, in a pure sample of elderly unipolar delusional depressives as well as to test their external validity against a set of demographic, anamnestic and psychopathological validators.

Methods:

Fifty inpatients suffering from psychotic major depression (PMD) in the context of major depressive disorder, 60 years old or older, were assessed on the basis of SCID IV, HRSD, MMSE and by three - point ordinal scales of twelve clinical, intrinsic or relational characteristics of delusions tested for their interrater reliability.

Results:

Principal Component Analysis resulted in the extraction of five factors, jointly accounting for 69.7% of the total variance. The five factors were interpreted as representing the dimensions of delusional strength, acute upsetting, delusional organization, incomprehensibility and incitation to actions. Most of the factors were differentially associated with patients’ demographic, anamnestic and clinical variables.

Conclusion:

Our results overlap in part with those of another similar study in delusional depressives of all age-ranges, differing, however in respects possibly attributable to peculiarities of elderly depressives. Overall, the findings of the present study contribute to the further elucidation of major clinical dimensions of delusions in PMD in the elderly and the testing of their external validity.

on the Differential Diagnosis of Obsessive-compulsive Symptoms in Schizophrenia: A Conceptual and Clinical Analysis

Several shortcomings of the current psychodiagnostic manuals (DSM-IV, ICD-10) with respect to obsessive-compulsive disorder, such as the diagnostic parity of obsessions and compulsions and the deficient conceptualization of compulsions might artificially inflate the clinical prevalence of obsessive-compulsive (OC) symptoms in the course of schizophrenic disorders. Still, one cannot exclude on purely a priori grounds the possibility of a genuine coexistence of OC symptoms along with delusions in patients with schizophrenia. the aim of the present study was to provide a contrastive conceptual analysis of typical features of obsessions versus those of delusions and correlatively of compulsions versus delusionally-motivated repetitive behaviours, supplemented by four relevant vignettes as clinical tests of its adequacy. Although preliminary, the results of our conceptual and illustrative analyses suggest that General Psychopathology can afford the conceptual resources for the accurate differential diagnosis obsession/compulsions from delusions/delusionally-motivated repetitive behaviours. in turn, this would provide a more solid clinical ground for the investigation of the epidemiology and the pathophysiology of OC symptoms in schizophrenic disorders.

Abduction of Children by Their Parents: The Psychopathological Approach of the Problem in Mixed-ethnicity Marriages

Introduction:

Children abduction by one parent and their transport refers to a foreign country is a gradually increasing phenomenon worldwide as well as Greece. Data from the Greek Ministry of Justice show that the frequency of such incidences is up to one a day (360/year). Some but not all of these cases come to the attention of the International Social Services (Division of Greece).

Method:

Records of fifty (50) cases of inter family abduction were obtained. These were cases that took place during the year 2003. These records were studied and analysed. The majority of cases concerned abductions within the European Union. Permission from the Personal Data Protection service was obtained before the research.

Results:

It was found that fathers were predominantly the abductors (60%). Based on the medical records of the parents, the abductor had established psychopathology (fathers 51,1%; mothers 48,5%). The abducting fathers made significant use of violence (50%) compared to the mother abductors (20%). The legal procedures that ensued the abductions were particularly prolonged: The trial period until the reach of a verdict took an average of 3 years.

Conclusions:

In the cases of children abduction by a parent, there is high correlation between the action and the psychopathology of the abductor. The need for establishment of services appropriate to face this multidisciplinary problem is imminent. The long time each case takes to be resolved has obvious implications for the mental health of the children and the parents involved.

Male depression: Discrete differences between the two sexes

Recent research indicates that subtle differences may exist in the symptom profile of male and female depression. The aim of this review is to examine male/female differences in depressive psychopathology in light of the latest research findings and discuss whether these differences might suggest the need for gender specific treatments. Multiple searches using Medline (1985-2008) were carried out. Additional searches were made using the reference lists of published papers and chapters from books. Differences exist in the clinical profile and comorbidity of male and female individuals with depression. Subtle genetic differences, the role of hormones, the role of preexisting anxiety, and personality differences are some of the factors responsible for these findings. These differences imply that different treatment options should be available for males and females suffering from depression. The available data suggest that clinically relevant differences in depressive symptom profile and the underlying pathophysiology between genders in depression do exist. The identification of distinct endophenotypes for major depression, will not only improve our understanding of the disease, but will also contribute to more specific treatment strategies.

Quetiapine monotherapy in bipolar disorder: Two years maintenance treatment in an elderly woman

Queatiapine has been used in bipolar mania and most recently in bipolar depression with good results. However its use in maintenance treatment has not been established yet. A case of an elderly woman suffering from bipolar disorder and diabetes mellitus (type II) is presented. The use of quetiapine as a monotherapy (300 mg/day) was efficient and safe and proved to be a good treatment in mood stabilization for two years.

Neuropsychological relationships in paranoid schizophrenia with and without delusional misidentification syndromes. A comparative study

Delusional misidentification syndromes (DMSs) and schizophrenia are strongly associated, since the former occur predominantly in the context of paranoid schizophrenia. However, the possible underlying neuropsychological relationships between DMSs and paranoid schizophrenia have not been thoroughly investigated. The aim of the present study was to investigate whether DMSs in paranoid schizophrenia are associated with a distinct neuropsychological substrate indicative of differential bilateral frontal and right hemisphere dysfunction. We compared two matched groups of paranoid schizophrenic patients with (N=22) and without (N=22) DMS(s) on a battery of neuropsychological tests assessing mainly frontal and right hemisphere functions. No statistically significant differences were detected between the two groups. Our findings are indicative of a bilateral frontal and right hemisphere dysfunction of equal severity in both DMS and non-DMS patients with paranoid schizophrenia.

[Hospital anxiety and depression scale (HADS): Validation in a Greek general hospital sample]

The Hospital Anxiety and Depression Scale (HADS) has been translated and widely used in several countries to assess anxiety and depression in general hospital patients with good results. Material-Method The HADS was administered to 521 participants (275 controls and 246 inpatients and outpatients of Internal Medicine and Surgical Departments). The Beck Depression Inventory (BDI) and the State-Trait Anxiety Inventory (STAI) were used as "gold standards" for depression and anxiety respectively. Results The HADS presented high internal consistency; Cronbach's α=0.884 (0.829 for anxiety and 0.840 for depression) and stability (test-retest Intraclass Correlation Coefficient 0.944). Factor analysis showed a two-factor structure. The HADS showed high concurrent validity; the correlations of the scale and its subscales with the BDI and the STAI were high (0.722-0.749).

CONCLUSIONS

The Greek version of HADS showed good psychometric properties and could prove as a good tool for clinicians to assess anxiety and depression in general hospital patients.

Sublingual use of olanzapine in combination with alprazolam to treat agitation in a terminally ill patient receiving parenteral nutrition

This paper reports the case of a 64-year-old man who was receiving parenteral nutrition after repeated operations due to stomach cancer. Olanzapine (orally disintegrating tablets) in combination with alprazolam was used successfully to relieve this terminally ill patient's anxiety and tension improving his relationship with his physicians and his daily life.

Set shifting deficits in melancholic vs. non-melancholic depression: preliminary findings

Twenty-two patients with major depressive disorder, 11 of them with melancholic features, and 11 controls were investigated with CANTAB subtests focusing in visual memory/learning and executive functions. Melancholic patients performed worse than the other groups in all tasks and manifested a significant impairment in set shifting. The results are discussed in association with prefrontal dysfunction.

Prolactin responses to acute clomipramine and haloperidol of male schizophrenic patients in a drug-free state and after treatment with clozapine or with olanzapine

Atypical neuroleptics share a common feature, showing higher affinity for 5-HT2 receptors than for D2 dopamine receptors, but show considerable differences in their clinical and pharmacological properties. In clinical doses, they occupy serotonergic receptors near saturation, but show considerable differences regarding the D2 receptor occupancies, with clozapine showing the lowest degree of occupation. We assessed serotonergic and dopaminergic receptor responsiveness in two groups of male schizophrenic patients, one treated with the atypical neuroleptic clozapine (14 patients, doses 200-600 mg/d) and the other treated with olanzapine (11 patients, doses 10-30 mg/d). We measured the prolactin responses to the acute administration of a serotonergic drug, clomipramine, and a dopaminergic one, haloperidol. Tests were first performed in the drug-free state, and were repeated after the patients had been treated with stable doses of either drug for six weeks. Clomipramine administration induced significant increases of prolactin in the drug-free state. These responses were eliminated after treatment of the patients with either drug, thereby indicating a high 5-HT receptor occupancy by both clozapine and olanzapine. The prolactin responses to haloperidol were not altered after treatment with clozapine, but were significantly reduced after the olanzapine treatment. The baseline prolactin levels were not influenced by clozapine treatment, and were moderately but significantly increased after treatment with olanzapine. The results indicate that there is a difference between the two drugs in their capacity to block dopamine receptors at the hypothalamus-pituitary level, and match the results obtained by SPECT receptor binding studies for striatal dopamine receptors.

Changes in dopamine receptor responsivity during alcohol detoxification may predict relapse

In the search for clinical and biological variables that may predict relapse of alcohol dependent patients after detoxification, we followed up for 1 year male patients that had undergone successful detoxification. The patients had been tested earlier during their usual alcohol consumption and immediately after detoxification for the responsivity of D2 dopamine receptors (as measured by the increases in prolactin plasma levels caused by intramuscular administration of 5 mg of the dopamine receptor blocker haloperidol). Of the 18 patients, eight had not consumed alcohol for more than 6 months, and ten had relapsed within 6 months. Comparison of the clinical and neuroendocrine data for the two subgroups revealed no significant differences in age, amount of alcohol consumed during alcohol abuse, score in the Beck Depression Inventory, score in the Brief Michigan Alcoholism Screening Test, or prolactin responses to haloperidol before detoxification. In patients who relapsed, the duration of alcoholism was marginally shorter (P=0.055). Patients who did not relapse had significantly higher (P=0.003) prolactin responses to haloperidol in the test performed after detoxification as compared with patients who did relapse, and their responses were similar to those of a group of healthy male subjects. The results show that the increase in dopamine receptor responsivity that occurs after detoxification is a favourable factor for non-relapse; it may reflect recovery from down-regulation of the dopaminergic reward system caused by alcohol consumption.
