[Changes in sleep patterns and the doom-scrolling (doom-surfing) phenomenon as modifiable risk factors for anxiety due to continuous stress of the COVID-19 pandemic]

OBJECTIVE

To evaluate the modifiable daily behavior patterns associated with increased anxiety indicators in the general population in response to the COVID-19 pandemic.

MATERIAL AND METHODS

The study examined the characteristics of the Russian population (n=7777) of the international multicenter project COMET-G. In particular, variables were targeted to describe deviations in the behavior of adults during the period of application of measures of social isolation in connection with the pandemic, and revealing a relationship with the total score on the Spielberger State Anxiety Scale (STAI-S). Among these variables, experts selected those that could potentially be subject to change in the short term, that is, act as manageable or modifiable risk factors for the development of anxiety. The selected variables were analyzed in a statistical PLS-model to identify indicators that make the most significant contribution to the increase in the total anxiety score.

RESULTS

Our statistical model explained 48.4% of the variability in the STAI-S anxiety total scores related to changes in daily life habits. In particular, doom-scrolling/doom-surfing about the spread of the virus and the COVID-19 pandemic, changes in sleep patterns and usual daily life activities due to social isolation measures presented as factors significantly contributing to the increase of state anxiety.

CONCLUSION

Given the manageable or modifiable risk factors that we have identified, public awareness and therapeutic recommendations, pointing to the need to (I) control the amount of time spent in the internet and monitor their internet-based content consumption, (II) regulate sleep-wake patterns, (III) maintain daily habits and household activities, may reduce the likelihood of developing anxiety disorders in the context of the impact of a global chronic stress due to the COVID-19 pandemic and associated social isolation measures.

Sociodemographic Factors of Depression During the COVID-19 Pandemic in Malaysia: the COVID-19 Mental Health International Study

OBJECTIVES

To determine the prevalence of depression and the sociodemographic factors associated with depression in Malaysia during the COVID-19 pandemic METHODS. This study is part of the COVID-19 Mental Health International Study to collect data on the impact of the pandemic on mental health through an online survey. People who were aged ≥18 years, able to read Malay or English, had access to the internet, and consented to participate were asked to complete a pro forma questionnaire to collect their sociodemographic data. The presence of distress and depression was assessed using the English or Malay version of the Center for Epidemiologic Studies Depression Scale.

RESULTS

Of 963 participants, 451 (46.8%) had depression and 512 (53.2%) had no depression who were either normal (n = 169, 17.5%) or had distress (n = 343, 35.6%). Participants had higher odds of having depression when living with two people (adjusted odds ratio [AOR] = 3.896, p = 0.001), three people (AOR = 2.622, p < 0.001) or four people (AOR = 3.135, p < 0.001). Participants with three children had higher odds of having depression (AOR = 2.084, p = 0.008), whereas having only one child was a protective factor for depression (AOR = 0.481, p = 0.01). Participants had higher odds of having depression when self-employed (AOR = 3.825, p = 0.003), retired (AOR = 4.526, p = 0.001), being housekeeper (AOR = 7.478, p = 0.004), not working by choice (AOR = 5.511, p < 0.001), or unemployed (AOR = 3.883, p = 0.009). Participants had higher odds of depression when living in a small town (AOR = 3.193, p < 0.001) or rural area (AOR = 3.467, p < 0.001). Participants with no chronic medical illness had lower odds of having depression (AOR = 0.589, p = 0.008).

CONCLUSION

In Malaysia during the COVID-19 pandemic, people who are living with two, three, or four people, having three children, living in a small town or rural areas, and having unstable income have higher odds of having depression. Urgent intervention for those at risk of depression is recommended.

Overall mortality trends in Greece during the first period of austerity and the economic crisis (2009-2015)

OBJECTIVES

The economic crisis and the resulting austerity in Greece led to a drastic reduction in healthcare spending, which has been assumed to have impacted people's health. This paper discusses official standardized mortality rates in Greece between 2000 and 2015.

METHODS

This study was designed to analyze population-level data and collected data from the World Bank, the Organisation for Economic Co-operation and Development, Eurostat, and the Hellenic Statistics Authority. Separate linear regression models were developed for the periods before and after the crisis and were compared.

RESULTS

Standardized mortality rates do not support a previously reported assumption of a specific and direct negative effect of austerity on global mortality. Standardized rates continued to decrease linearly, and their correlation to economic variables changed after 2009. Total infant mortality rates show an overall rising trend since 2009, but the interpretation is unclear because of the reduction in the absolute number of deliveries.

CONCLUSIONS

The mortality data from the first six years of the financial crisis in Greece and the decade that preceded do not support the assumption that budget cuts in health are related to the dramatic worsening of the overall health of the Greek people. Still, data suggest an increase in specific causes of death and the burden on a dysfunctional and unprepared health system that is working in an overstretched manner trying to meet needs. The dramatic acceleration of the aging of the population constitutes a specific challenge for the health system. HIPPOKRATIA 2022, 26 (3):98-104.

Employment insecurity, mental health and suicide

With the economic crisis an increase in suicidality has been reported across Europe but especially in Greece. Τhese reports hit the mass media headlines and were also included in the debate among political parties. The literature suggests that during periods of deep economic crisis, there is an increase specifically in suicides but causality remains unclear. The prevailing picture both in the scientific literature and in the mass media is that the economic crisis acts as a more or less generic risk factor on the entire population putting at risk literally anybody. Two recent studies clearly dispute it by reporting that suicides had increased several months before unemployment increased. Additionally and specifically concerning Greece, where the economic crisis is deeper and more prolonged, the detailed inspection of age and gender specific rates are not in accord with a "male gender" by "unemployment" interaction. Taking into consideration the above and since the rise in suicides also affects prospering countries without high unemployment, including Germany and Norway, another possible explanation is that the changes in the socioeconomic environment and especially in the employment conditions have overstressed vulnerable populations (e.g. mental patients) leading to the increased suicide rates. The problem is that in the majority of the literature the economic crisis/austerity is considered to be a generic risk factor affecting the entire population and subsequently generic horizontal measures are proposed. Unfortunately patients at risk to commit suicide are not considered as such; instead they are rather considered as normal healthy people from the general population who respond with suicide to generic adverse events.

[The concept of temperament and its contribution to the understanding of the bipolar spectrum]

The present article attempts first to provide a historical overview of the concept of temperament,The present article attempts first to provide a historical overview of the concept of temperament,since its foundation by Polybos (4th century B.C.) and the school of Cos, its predominant role in theshaping of the anthropological and humanitarian sciences, until the modern theoretical formulations,such as those proposed by Robert Cloninger and Hagop Akiskal. Secondly, recent literature ispresented, which suggests a strong link of different temperament structures to mental health andpsychopathology. Hans Eysenck (1916-1997) was the first psychologist to establish approaches topersonality differences and to distinguish three dimensions of personality: Neuroticism, Extraversionand Psychotisism. Eysenck was followed by McCrae and Costa who proposed that there are five basicdimensions of personality ("Big Five"). In the mid-1980s, Robert Cloninger developed a distinctivedimensional model of temperament and character traits. Hagop Akiskal emphasized on the affectivecomponents of temperament and their possible connections to mood disorders and creativity.Specifically, temperament assessment seems to help in differentiating between the relationship ofvarious temperaments and the clinical manifestations of bipolar illness. Within the area of mood disorders,specific affective temperaments might constitute vulnerability factors, as well as clinical pictureand illness course modifiers. Viewing mood disorders under this prism gives birth to the concept ofthe bipolar spectrum with major implications for all aspects of mental health research and providingof care. The hyperthymic and the depressive temperaments are related to the more 'classic' bipolarpicture (that is euphoria, grandiose and paranoid thinking, antisocial behavior, psychomotor accelerationand reduced sleep and depressive episodes respectively). On the contrary cyclothymic, anxiousand irritable temperaments are related to more complex pictures and might predict poor responseto treatment, violent or suicidal behavior and high comorbidity. Unipolar disorder diagnosis is oftenchanged due to the fact that a manic or mixed episode can occur after several years of treatment failure.In these cases the evaluation of temperament can prove to be effective in distinguishing betweenunipolar and bipolar depression and thus favoring treatment planning. In addition, temperament assessmentchanges the definition of bipolarity by supporting the concept of "bipolar spectrum". This isa factor that can lead to a rise in prevalence of bipolar cases. Furthermore, the evaluation of temperamenthas shifted our understanding of bipolarity towards the concept of the 'bipolar spectrum'. It hasalso led to an increase in the prevalence of bipolar disorder cases, notably bipolar II, and a decrease in unipolar cases. Finally, incorporating the concept of temperament in our understanding of bipolardisorder constitutes a challenging issue, which can lead to better treatment and outcome of patients.

Solar insolation in springtime influences age of onset of bipolar I disorder

OBJECTIVE

To confirm prior findings that the larger the maximum monthly increase in solar insolation in springtime, the younger the age of onset of bipolar disorder.

METHOD

Data were collected from 5536 patients at 50 sites in 32 countries on six continents. Onset occurred at 456 locations in 57 countries. Variables included solar insolation, birth-cohort, family history, polarity of first episode and country physician density.

RESULTS

There was a significant, inverse association between the maximum monthly increase in solar insolation at the onset location, and the age of onset. This effect was reduced in those without a family history of mood disorders and with a first episode of mania rather than depression. The maximum monthly increase occurred in springtime. The youngest birth-cohort had the youngest age of onset. All prior relationships were confirmed using both the entire sample, and only the youngest birth-cohort (all estimated coefficients P < 0.001).

CONCLUSION

A large increase in springtime solar insolation may impact the onset of bipolar disorder, especially with a family history of mood disorders. Recent societal changes that affect light exposure (LED lighting, mobile devices backlit with LEDs) may influence adaptability to a springtime circadian challenge.

[Non-conventional pharmacological agents for the treatment of bipolar disorder: Α systematic review of the evidence]

Bipolar disorder (BD) has a complex and variable clinical picture which is characterized by many different phacets and phases and as a result its therapeutical options are also complex and often unsatisfactory. Typically the so-called "mood stabilizers" are used in the treatment of BD and in this class lithium and specific antiepileptics are included. The present study aimed to systematically review the literature concerning the presence of randomized double blind clinical trials of 'non conventional' pharmaceutical treatment options. The present systematic review utilized the PRISMA method and searched the MEDLINE through January 1st 2015 with the use of appropriate key words. In order to identify randomized controlled trials- RCTs a combination of the words "bipolar", "manic", "mania", "manic depression" and "manic depressive" with "randomized" was used. Webpages with lists of trials were also searched including http://clinicaltrials.gov and http://www.clinicalstudyresults.org as well as the official webpages of all pharma companies with products marketed in the treatment of BD. The reference lists of various review papers were also searched. The MEDLINE was searched with the combination of the words "guidelines" or "algorithms" with "mania", "manic", "bipolar", "manicdepressive" or "manic depression" in order to identify articles with treatment guidelines. The reference list of these articles were also scanned. From 3,284 papers which were initially traced, only 47 papers were included in the present study. From those agents studied in acute mania, tamoxifen is efficacious as monotherapy and as combination therapy with lithium and other mood stabilizers, however its safety profile is relatively poor. Allopurinol manifests efficacy in combination with lithium but not with other agents and its safety profile is satisfactory. Methoxyprogesterone is efficacious in combination with mood stabilizers and its safety profile is very good. In acute bipolar depression the combinations of FEWP with carbamazepine and ketamine, modafinil, pramipexole, pregnenolone and maybe armodafinil with mood stabilizers are efficacious. The safety profile of these combinations is medium. The use of celecoxib, lisdexamfetamine and memantine have negative data. Concerning the maintenance treatment, the data are negative for memantine and for Nacetylcysteine. Although most of the data concerning the usefulness of "non-conventional" pharmacotherapeutic agents in the treatment of bipolar disorder are negative, it is encouraging that those agents who have been proven efficacious probably exert their therapeutic effect through pathways which differ from usual and probably different from those classically considered in most biological models of bipolar illness. In this way there constitute new paradigms and open new horizons in the understanding of the disease.

Therapeutic approaches to age-associated neurocognitive disorders

The United Nations projects that the number of individuals with dementia in developed countries alone will be approximately 36,7 million by the year 2050. International recognition of the significant emotional and economic burden of Alzheimer's disease has been matched by a dramatic increase in the development of pharmacological and nonpharmacological approaches to this illness in the past decade. Changing demographics have underscored the necessity to develop similar approaches for the remediation of the cognitive impairment associated with more benign syndromes, such as mild cognitive impairment (MCI) and age-associated cognitive decline (AACD). The present article aims to provide an overview of the most current therapeutic approaches to age-associated neurocognitive disorders. Additionally, it discusses the conceptual and methodological issues that surround the design, implementation, and interpretation of such approaches.

Problems in determining efficacy and effectiveness of antidepressants

Antidepressants play the major role in treating depressive patients not only due to the fact that they have to undergo the most rigorous proof of efficacy but also because they are easy to apply in the everyday clinical practice. Nearly all psychiatrists and general practitioners treating depressive patients agree about the relevance of antidepressants in the treatment of depressive patients. However, a number of meta-analytic studies recently challenged this belief and it has been put up for discussion to psychiatry/clinical psychopharmacology whether the efficacy of antidepressants is clinically relevant. Despite that all medication were judged to have sufficient data to receive approval from the FDA and the EMA and other agencies worldwide, some authors went further and questioned the effectiveness of antidepressants. They even proposed that "alternative" therapies of unproven efficacy or of proven negative efficacy should be preferred to medication. These authors do not take into consideration that for methodological reasons it is not acceptable to deduce too extensive conclusions. Some assumptions they rely on, like the suggestion of NICE, which regards a mean placebo-verum difference of 3 HAM-D points as clinically relevant, is downright arbitrary on statistical grounds, and not supported by empirical findings or by expert opinion. It seems that the difference in change in HAM-D score between the active drug and placebo is somewhere between 2 and 3, with maybe some agents performing a little better than others. It is uncertain whether initial severity determines response; different interpretations exist. However, much more important for the evaluation of the clinical relevance is the result of the responder/remitter analysis, which compares the relative frequency of these categories between the placebo and verum groups. This approach results in a number needed to treat (NNT) of 5-7. In evidence-based medicine such a NNT is traditionally regarded as a sign of moderate to strong efficacy and corresponds to the referring values of many therapies, which e.g. are standard therapies in internal medicine. However, from many meta-analyses it is clear that when concepts of evidence-based medicine and health economy are applied, which are far away from clinical thinking, problems occur and results are very difficult to interpret in clinical terms.

[Development of the Risk Assessment Suicidality Scale (RASS): a population-based study]

Suicide and suicide attempts are significant and costly public health problems. In order to prevent suicidal and other self-injurious behavior, research on the multiple factors involved in these behaviors with comprehensive and user-friendly instruments is necessary. The aim of the current study was to construct a self-report instrument with emphasis on the items which describe suicide-related behavior itself rather than strongly related clinical features on the basis of a general population study. Twelve items comprising a new scale were applied to 734 subjects from the general population (40.6% males and 59.4% females) aged 40.8 +/- 11.5, along with the STAI and the CES-D. The scoring method was developed on the basis of frequency table of responses to the individual scale items. The factor analysis returned 3 factors explaining 59.19% of total variance (Intention, Life, and History). The Cronbach's alpha was 0.85 for the Intention, 0.69 for the Life and 0.52 for the History subscale. The RASS is a reliable and valid instrument which might prove valuable in the assessment of suicidal risk in the general population as well as in mental patients.

Towards a genetically validated new affective temperament scale: a delineation of the temperament phenotype of 5-HTTLPR using the TEMPS-A

BACKGROUND

Although it has been described that affective temperaments are associated with the 5-HTTLPR, less attention was paid to the association between this polymorphism and subscales and items related to each affective temperament. The aim of our study was to investigate the association of affective temperament subscales and individual items with the s allele of the 5-HTTLPR.

METHOD

138 psychiatrically healthy women completed the TEMPS-A questionnaire and were genotyped for 5-HTTLPR. Scores of subjects on the temperament scales, subscales and items in the three genotype and the two phenotype groups were compared using ANOVA. We selected items with significantly different mean scores between the three genotype groups and the two phenotype groups separately and performed item analysis.

RESULTS

Subjects in the different 5-HTTLPR genotype and phenotype groups have significantly different score on scales measuring depressive, cyclothymic, irritable and anxious temperaments, and several subscales composing these temperamental scales. Subjects in the three genotype groups scored significantly different on 11 items, 8 of these remained in a derived genotype scale after item analysis. Subjects in the two phenotype groups had significantly different scores on 12 items, 9 of them were retained in a derived phenotype scale after item analysis.

LIMITATIONS

Our sample was relatively small and included only women.

CONCLUSIONS

Our data provide support for the association of affective temperaments with the s allele. Although the cyclothymic temperament shows the strongest association, all temperaments within the depressive superfactor have a similar share in this association. The newly derived 5-HTTLPR Phenotype Scale shows strong association with 5-HTTLPR genotype and phenotype, therefore this scale should be further investigated in relation to psychiatric disorders, as well as psychological traits and temperaments.

Is it possible to predict the long-term response to venlafaxine with the use of biological markers and psychophysiological methods?

INTRODUCTION

The present study investigated whether it is possible to predict the medium term response to venlafaxine using biological markers and psychophysiological methods.

MATERIAL

Fourteen (14) patients aged 21-60 years suffering from Major Depression according to DSM-IV were included in the study.

METHODS

The SCAN v 2.0 and the IPDE were used to assist clinical diagnosis. Patients were investigated with electrooculogram (EOG), Pattern-Reversal Visual Evoked Potentials (PR-VEPs), Dexamethasone Suppression Test (DST), D-fenfluramine Challenge Test, and brain Single Photon Emission Tomography (SPECT). Venlafaxine 150-225 mg per os daily was administered. The follow-up period was 2 years.

STATISTICAL ANALYSIS

Chi-square test and ANOVA were used for the analysis of data.

RESULTS

There was a lower left globus pallidus regional cerebral blood flow in patients with better response. On the contrary, chronic patients were closer to normality.

DISCUSSION

The results of the current study provide preliminary evidence concerning our ability to predict response to venlafaxine and to understand its way of action.

Beneficial effect of long-acting injectable risperidone on the neurocognitive deficit of a schizophrenic patient: a case report

We report the case of a 37-year-old female patient suffering from schizophrenia, disorganized type. Adherence to treatment was always a major problem. During the last 2 years the patient was disorganized and was refusing treatment. Since the patient was already receiving a very high (double) dose per os, it was decided to administer two 50 ml ampoules of long-acting, injectable risperidone plus 5 mg of haloperidol per os daily. After 80 days of treatment, all positive, negative and even neurocognitive symptoms improved markedly. Extrapyramidal side effects did not appear at any stage of treatment. The most impressive neurocognitive improvement concerned the clock drawing test, which was in parallel with her improvement in both the positive and negative symptoms of the PANSS.

Treatment guidelines for bipolar disorder: a critical review

INTRODUCTION

The development of treatment guidelines emerged as an important element so as to standardize treatment and to provide clinicians with algorithms, which would be able to carry research findings to the everyday clinical practice.

MATERIAL AND METHOD

The MEDLINE was searched with the combination of each one of the key words 'mania', 'manic', 'bipolar', 'manic-depression', 'manic-depressive' with 'treatment guidelines'.

RESULTS

The search was updated until March 1st, 2004 and returned 224 articles. Twenty-seven papers concerning the publication of treatment algorithms were traced.

DISCUSSION

Despite supposedly being evidence-based, guidelines for the treatment of bipolar disorder vary significantly across committees or working groups. Overall, however, at the first stage of the mania/hypomania algorithm, monotherapy with lithium, divalproex sodium or olanzapine is generally recommended. At latter stages combination therapy is strongly recommended. It is clearly stated that in bipolar depression antidepressants should be used only in combination with antimanic agents in order to avoid switching of phases. During the maintenance phase all patients should receive antimanic agents, while some may need the addition of antidepressants. The most recent guidelines emphasize the use of atypical antipsychotics for mania and lamotrigine for depression. The main problem with guidelines is that they are rapidly outdated and that the evidence base relies mainly on registration monotherapy trials that hardly reflect treatment in routine clinical conditions.

CONCLUSION

Treatment guidelines may be useful to avoid non-evidence-based treatment decisions, but they are quickly out-of-date and may not fully apply to the clinical setting. The more recent guidelines point the value of atypical antipsychotics, lithium, and valproate in the treatment of mania; the role of lithium, lamotrigine, and olanzapine as options for maintenance therapy; and the scarcity of options for the treatment of bipolar depression. Psychoeducation is also supported by most guidelines as an adjunctive treatment.

Relationship among Dexamethasone Suppression Test, personality disorders and stressful life events in clinical subtypes of major depression: An exploratory study

Background

The present study aimed to investigate the relationship between dexamethasone suppression test, personality disorder, stressful life events and depression.

Material

Fifty patients (15 males and 35 females) aged 41.0 ± 11.4 years, suffering from Major Depression according to DSM-IV criteria entered the study.

Method

Diagnosis was obtained with the aid of the SCAN v 2.0 and the IPDE. Psychometric assessment included the HDRS, HAS, the Newcastle Scale (version 1965 and 1971), the Diagnostic Melancholia Scale, the Personality Deviance Scale and the GAF scale. The 1 mg DST was used.

Statistical Analysis

Included MANOVA, ANOVA with LSD post hoc test and chi-square test.

Results

Sixteen (32%) patients were non-suppressors. Eight patients without Personality Disorder (PD) (23.5%), and 5 of those with PD of cluster B (50%) were non-suppressors. Atypical patients were the subtype with the highest rate of non-suppression (42.85%). No difference between suppressors and non-suppressors was detected in any of the scales.

Discussion

The results of the current study suggest that pathological DST is not a core feature of major depression. They also suggest that there are more than one subtypes of depression, concerning the response to stress. It seems that the majority of depressed patients (50%) does not experience high levels of stress either in terms of self reported experience or neuroendocrine function. The rest of patients however, either experience high levels of stress, or manifest its somatic analogue (DST non-suppression) or have a very low threshold of stress tolerance, which makes them to behave in a hostile way.

The relationship between job stress, burnout and clinical depression

The definition and phenomenological features of 'burnout' and its eventual relationship with depression and other clinical conditions are reviewed. Work is an indispensable way to make a decent and meaningful way of living, but can also be a source of stress for a variety of reasons. Feelings of inadequate control over one's work, frustrated hopes and expectations and the feeling of losing of life's meaning, seem to be independent causes of burnout, a term that describes a condition of professional exhaustion. It is not synonymous with 'job stress', 'fatigue', 'alienation' or 'depression'. Burnout is more common than generally believed and may affect every aspect of the individual's functioning, have a deleterious effect on interpersonal and family relationships and lead to a negative attitude towards life in general. Empirical research suggests that burnout and depression are separate entities, although they may share several 'qualitative' characteristics, especially in the more severe forms of burnout, and in vulnerable individuals, low levels of satisfaction derived from their everyday work. These final issues need further clarification and should be the focus of future clinical research.

Reliability, validity and psychometric properties of the Greek translation of the Major Depression Inventory

BACKGROUND

The Major Depression Inventory (MDI) is a brief self-rating scale for the assessment of depression. It is reported to be valid because it is based on the universe of symptoms of DSM-IV and ICD-10 depression. The aim of the current preliminary study was to assess the reliability, validity and psychometric properties of the Greek translation of the MDI.

METHODS

30 depressed patients of mean age 23.41 (+/- 5.77) years, and 68 controls patients of mean age 25.08 (+/- 11.42) years, entered the study. In 18 of them, the instrument was re-applied 1-2 days later and the Translation and Back Translation made. Clinical diagnosis was reached with the use of the SCAN v.2.0 and the International Personality Disorders Examination (IPDE). The Center for Epidemiological Studies-Depression (CES-D) and the Zung Depression Rating Scale (ZDRS) were applied for cross-validation purposes. Statistical analysis included ANOVA, the Spearman Product Moment Correlation Coefficient, Principal Components Analysis and the calculation of Cronbach's alpha.

RESULTS

Sensitivity and specificity were 0.86 and 0.94, respectively, at 26/27. Cronbach's alpha for the total scale was equal to 0.89. The Spearman's rho between MDI and CES-D was 0.86 and between MDI and ZDRS was 0.76. The factor analysis revealed two factors but the first accounted for 54% of variance while the second only for 9%. The test-retest reliability was excellent (Spearman's rho between 0.53 and 0.96 for individual items and 0.89 for total score).

CONCLUSION

The current study provided preliminary evidence concerning the reliability and validity of the Greek translation of the MDI. Its properties are similar to those reported in the international literature, but further research is necessary.

Reliability and cultural applicability of the Greek version of the International Personality Disorders Examination

BACKGROUND

The International Personality Disorders Examination (IPDE) constitutes the proposal of the WHO for the reliable diagnosis of personality disorders (PD). The IPDE assesses pathological personality and is compatible both with DSM-IV and ICD-10 diagnosis. However it is important to test the reliability and cultural applicability of different IPDE translations.

METHODS

Thirty-one patients (12 male and 19 female) aged 35.25 +/- 11.08 years, took part in the study. Three examiners applied the interview (23 interviews of two and 8 interviews of 3 examiners, that is 47 pairs of interviews and 70 single interviews). The phi coefficient was used to test categorical diagnosis agreement and the Pearson Product Moment correlation coefficient to test agreement concerning the number of criteria met.

RESULTS

Translation and back-translation did not reveal specific problems. Results suggested that reliability of the Greek translation is good. However, socio-cultural factors (family coherence, work environment etc) could affect the application of some of the IPDE items in Greece. The diagnosis of any PD was highly reliable with phi >0.92. However, diagnosis of non-specific PD was not reliable at all (phi close to 0) suggesting that this is a true residual category. Diagnosis of specific PDs were highly reliable with the exception of schizoid PD. Diagnosis of antisocial and Borderline PDs were perfectly reliable with phi equal to 1.00.

CONCLUSIONS

The Greek translation of the IPDE is a reliable instrument for the assessment of personality disorder but cultural variation may limit its applicability in international comparisons.

Morning and evening plasma melatonin and dexamethasone suppression test in patients with nonseasonal major depressive disorder from northern Greece (latitude 40-41.5 degrees )

INTRODUCTION

The present study aimed to search for correlations between melatonin (MT) levels and the dexamethasone suppression test (DST) and clinical variables.

METHODS

Fifty depressed patients aged 21-60 years took part in the study. The Schedules for Clinical Assessment in Neuropsychiatry, version 2.0, and the International Personality Disorders Examination were used for diagnosis. Psychometric assessment included the Hamilton Depression Rating Scale, the Hamilton Anxiety Scale, the General Assessment of Funtioning Scale, the Newcastle scales and the Diagnostic Melancholia Scale. The DST and 9.00 and 23.00 h MT values were assessed. Statistical analysis included Student's t test, Pearson product moment correlation coefficient and forward stepwise multiple linear regression analysis.

RESULTS

Melancholic patients had lower 23.00 h MT values in comparison to the rest of the patients and the atypical and 'undifferentiated' patients.

CONCLUSION

The current study shows that low MT values were closely related to melancholic depression. Distinct quality of mood, psychomotor agitation or retardation and anorexia or weight loss seemed to be responsible for this relationship.

Neurophysiological investigation of cervical spondylosis

The difficulties in diagnosing spinal cord lesions due to the cervical spondylosis is well-known in clinical neurology. In order to investigate the contribution of various neurophysiological examinations in the diagnosis in cervical spondylosis, we examined 70 patients suffering from cervical spondylosis, with peripheral nerve conduction studies, F-wave from the upper limb and electromyography from the corresponding muscles, as well as somatosensory evoked potentials (SEPs) from upper and lower limbs. Patients were separated into four groups: 20 patients had cervical spondylosis symptoms only; 15 patients had symptoms and signs of spinal root involvement; 15 patients had symptoms and signs of myelopathy; and 20 patients had symptoms and signs of both myelopathy and spinal root involvement. A group of 20 normal controls was also studied. In all groups of patients SEPs were the most sensitive electrophysiological study. Low-amplitude N13 and increased conduction time of N9-N13 and central conduction N13-N19 and LP-P27 were the most common finding in SSEP testing. SEPs were affected in many cases without CT-MRI findings of spinal cord pressure. From the above findings, SEPs proved to be the most sensitive diagnostic investigation in cervical spondylosis.

Difference in symptom profile between generalized anxiety disorder and anxiety secondary to hyperthyroidism

OBJECTIVE

The differential diagnosis between subclinical hyperthyroidism and Generalized Anxiety Disorder (GAD) is often a difficult problem to solve without laboratory examination. The aim of this pilot study was to assess whether there are differences in the symptom profile between these two disorders.

METHODS

Fifty patients took part in the study: Twenty-five were hyperthyroid patients, and twenty-five were GAD patients. The diagnosis was based on the TSH values and the DSM-IV criteria, respectively. The Hamilton Anxiety Scale (HAS) and the list of fifty-one symptoms produced by the detailed expansion of HAS items were used to quantify the anxiety symptomatology. The differences in the frequencies between the two diagnostic groups were calculated at each categorical response for every item of both scales. Forward Stepwise Discriminant Function Analysis was performed twice using HAS items and the fifty-one-list items.

RESULTS

The symptoms of anxiety in subclinical hyperthyroidism were not identical to those of GAD. Four Hyperthyroid/Anxiety Indices (HAI I-IV) were developed. These indices reach optimum classification of patients (3 of them reach 100% sensitivity and specificity).

CONCLUSION

The results of the current study suggest that it is possible to differentiate between GAD and subclinical cases of hyperthyroidism by the careful study of clinical symptomatology. This may be of particular help in isolated areas without laboratory support, but replication of the indices in other samples is indicated.

Correlation of rCBF (SPECT), CSF tau, and cognitive function in patients with dementia of the Alzheimer's type, other types of dementia, and control subjects

BACKGROUND

The diagnosis of Alzheimer's disease (AD) during life remains difficult and a definite diagnosis of AD relies on histopathological confirmation at post-mortem or by cerebral biopsy. It is well known that levels of tau proteins are consistently and significantly increased in the cerebrospinal fluid (CSF) of Alzheimer's patients versus levels in normal controls. However, the sole use of this biochemical marker as a test for AD is hampered by mediocre specificity, since tau concentrations may also be elevated in certain other neurological disorders (OND). Studies of the regional cerebral blood flow (rCBF) are widely performed because of their convenience and usefulness in a variety of neurological disorders. Most studies have reported high diagnostic accuracy for brain perfusion single-photon emission tomography (SPECT) in Alzheimer's disease.

METHODS

In order to improve specificity, in this study, correlation of 99mTc-HMPAO SPECT scanning and CSF tau protein levels was made in 117 patients with AD, 67 patients with OND (26 of which had other dementias), and 23 age-matched controls. Means and standard deviations of tau protein levels were 297, 42 +/- 221, 12 in AD patients and 78, 07 +/- 98, 51 in patients with OND (p = 0.0006). No correlation was noted between CSF tau protein levels and age, duration of the disease, and neuropsychological scores of mini-mental state examination (MMSE), Cambridge Cognitive Examination (CAMCOG), and Functional Rating Scale for Symptoms of Dementia (FRSSD).

FINDINGS

There was a bilateral parietal and temporal hypoperfusion in patients with AD in SPECT in comparison to normal subjects (p < 0.05) and there was a statistical correlation between this hypoperfusion and neuropsychological tests, such as MMSE and CAMCOG (p < 0.01). There was no correlation between tau protein levels and hypoperfusion in SPECT.

INTERPRETATION

Conclusively, the correlation between elevated levels of tau proteins and hypoperfusion in SPECT in AD patients therefore cannot improve the specificity of tests in AD and this means that the determination of CSF tau proteins levels is not a specific diagnostic test for AD.

Automated standardized pupillometry with optical method for purposes of clinical practice and research

The aim of the current study was the introduction and standardization of two experimental conditions for dynamic pupillometry. Pupillometry is a method that can provide valuable data concerning the functioning of the autonomous nervous system. The system for recording the pupil reaction was developed in the Laboratory of Clinical Neurophysiology of the 1st Department of Neurology of Aristotle University of Thessaloniki, in co-operation with the Laboratory of Fluid Mechanics of the Aristotle University of Thessaloniki. This system is fully automated. It includes an infra-red video camera, which has the capacity to record in complete darkness, and an SLE (clinical photic stimulator) lamp. A software application automatically performed all the procedures. During the first experiment, one flash was administered. During the second experiment, a series of 25 flashes (1 Hz frequency) was administered. Fifty physically and mentally healthy subjects aged 23-48 years took part in the study. Means, standard deviations and ranges for all variables characterizing normal subjects during both experimental conditions are reported. Test/re-test results and comparisons of the two eyes are also reported. The combined use of these two experimental conditions in dynamic pupillometry may be a very useful tool in medical research. There are already reports on the usefulness of pupillometry in the research of various diseases, including depression and Alzheimer's disease. It is expected that it will also be a valuable research tool in the study of diabetes, alcoholism, myasthenia gravis, cancer, multiple sclerosis, etc.

Changes in pupil reaction to light in Alzheimer's disease patients: a preliminary report

The aim of this preliminary study was to compare the pupil reaction to light in Alzheimer's disease (AD) patients before and after treatment and in normal controls. Ten AD patients diagnosed according to DSM-IV and NINCDS-ADRDA criteria (five medication-free and five under anticholinesterase treatment) and five age- and gender-matched controls took part in the study. Drug-free patients and all control subjects were free of any medication for at least four weeks. An optical method was used to assess the pupil reaction to a single flash. Medication-free AD patients manifested shorter latency and lower amplitude of maximum response to light in comparison to controls. These findings are in agreement with the presence of a cholinergic deficit in AD patients. Pharmacological treatment with donepezil, which is an anticholinesterase agent partially improves this deficit. The results of this preliminary investigation suggest that dynamic pupillometry could be a useful adjunct to assist the diagnosis of early AD, and the differential diagnosis between different types of dementia. AD patients seem to manifest a specific pattern of pupil reaction to light, and some characteristics of this pattern are detectable even in patients receiving anticholinesterase medication. However, this is only a preliminary report and further research is mandatory.

Burnout in nursing staff: is there a relationship between depression and burnout?

OBJECTIVE

There is evidence that burnout may be a clinical entity with pathological stress reaction features related to the inability in finding pleasure from work. The purpose of this study was to investigate the relationship between burnout and depression.

METHODS

The study took place in the general hospital AHEPA of Thessaloniki. All members of the nursing staff (in total 368 subjects) took part. The protocol was self-reported and anonymous, in order to obtain as valid data as possible and included the Maslach Burnout Inventory (MBI) to assess the level of burnout, the Eysenck Personality Questionnaire (EPQ) to assess personality traits, and the Zung Self-Rating Depression Scale to assess depressive symptomatology.

RESULTS

The analysis revealed a weak but significant relationship between burnout and depression.

CONCLUSIONS

Depression is a pervasive disorder that affects almost every aspect of the patient's life. On the contrary, burnout is, by definition, a syndrome restricted to the patient's professional environment. However, it seems that there may be two distinct types of burnout syndromes, of which the one comprising the majority of nurses has little or no common features with depression. The second type consists of individuals with a predisposition to develop burnout. The latter is characterized by more severe symptomatology, phenotypic similarity to depression and presumably common etiological mechanisms.

Validation of the epidemiological dementia index in geriatric outpatients

The aim of the current study was to test the properties of a scale especially developed for use in epidemiological surveys in low sociocultural populations, and to determine whether this scale can be used in a clinical population.

MATERIAL AND METHODS

Two hundred fifty subjects took part; 150 were controls and 100 had dementia of various types according to DSM-IV and NINCDS-ADRDA criteria.

RESULTS

Cronbach's alpha was equal to .78. In the group of people under 75 years old, sensitivity did not exceed 90%. Specificity was over 90% at the level 4/5. The respective scores for the group of people over 74 were 6/7 and 3/4.

DISCUSSION

The Epidemiological Dementia Index seems to be less powerful when used in a clinical population. This provides further evidence that it is not suitable to use the same instruments in both epidemiological studies and clinical practice.

Do depressive patients with family history of dementia constitute a separate group? A case report study

INTRODUCTION

Recently it has been suggested that patients with both depression and a family history of dementia are seven times as likely to develop Alzheimer's disease as are controls.

METHOD

Fifty patients aged 21 &#45 60 years suffering from DSM-IV Major Depression entered the study; three of them (6%) had a positive family history of dementia. Diagnosis was by SCAN v 2.0. The family history method was used to record family history. All depressed patients were investigated with the Dexamethasone Suppression Test (DST), brain SPECT, electro-oculogram (EOG), flash-electroretinogram (f-ERG) and Pattern-Reversal Visual Evoked Potentials (PR-VEPs). Student's t-test was used to analyse the results. All patients with positive family history had atypical features.

RESULTS

Two of them suffered from borderline personality disorder, in comparison to eight in the remainder of the sample and five in the rest of the atypicals. The age of onset of depression was lower. DST, SPECT, EOG and PR-VEPs findings were similar between groups. The only significant finding concerned the latency of the bs wave of the scotopic ERG (P < 0.01), but even in this, patients with positive history did not differ from the rest of the atypical patients.

CONCLUSION

The present study provided limited data connecting atypical features of depression, personality traits, psychological stressors, hypercortisolaemia and family history of dementia. Further research with larger samples is essential. ( Int J Psych Clin Pract 2000; 4: 215 - 222).

The validation of the short form of the Geriatric Depression Scale (GDS) in Greece

The Geriatric Depression Scale-15 (GDS-15) is a short, 15-item instrument specifically designed to assess depression in geriatric populations. Its items require a yes/no response. The Geriatric Depression Scale was first introduced by Yesavage et al. in 1983, and the short form (GDS-15) was developed by Sheikh and Yesavage in 1986. The aim of the current study was the standardization of the GDS-15 for use in Greece. Subjects were divided into Group A: 168 control subjects, and Group B: 103 patients suffering from clinically diagnosed depression. All were over 65 years of age. A score of 6/7 on the GDS-15 was found to be the best cut-off point for diagnosing depression in an elderly Greek population, with Sensitivity = 92.23 and Specificity = 95.24. GDS-15 manifests high internal consistency with Cronbach's alpha = 0.94, and all items seem to be equivalent. Factor Analysis of the GDS-15 revealed 4 factors: a cognitive (thought content), an affective, a functional, and a factor that reflects helplessness and fear for the future. The two diagnostic groups differed on all 4 factors scores at p-value <0.001.

Comparison of the diagnosis of melancholic and atypical features according to DSM-IV and somatic syndrome according to ICD-10 in patients suffering from major depression

While melancholic (according to DSM) or somatic syndrome (according to ICD) has strong historical roots and substantial empirical verification, the concept of atypical features is relatively new and not sufficiently studied. The aim of the current study was to investigate the reliability of these diagnostic subcategories in patients suffering from major depression in Greece. Forty patients (eight males and 32 females) aged 19-60 years (mean 39.3, sd 12.2) suffering from major depression according to DSM-IV criteria were studied. SCAN v.2.0 was used to assess symptomatology. The presence of each criterion according to DSM-IV and ICD-10 was registered. Frequency tables were developed and factor and cluster analysis were performed. The results of the analysis suggest the existence of three syndromes which roughly reflect the melancholic and atypical but also propose a third, which can be considered as an 'undifferentiated' syndrome. The DSM demand that the existence of melancholic features be excluded first and then that diagnosis of atypical features be made was confirmed.

Epidemiological dementia index: a screening instrument for Alzheimer's disease and other types of dementia suitable for use in populations with low education level

INTRODUCTION

MMSE and CAMCOG are neuropsychological scales developed for use in everyday clinical practice and epidemiological surveys.

MATERIAL AND METHODS

These two instruments were used as part of the assessment during an epidemiological survey in the municipality of Pylaia, Greece. The project was based on the World Health Organization Program for Research on Aging and Age-Associated Dementias (1992). It had two phases. During phase I, nursing students collected demographic data, risk factors, personal and family history data and they applied MMSE, CAMCOG and scales of everyday life functioning. During phase II, 4 physicians examined all subjects that manifested possible cognitive deterioration (MMSE<27), in order to reach a final diagnosis. The final diagnosis was made according to DSM-IV and NINCDS-ADRDA criteria. MMSE and CAMCOG were not taken into consideration in the diagnostic process. Three hundred and eighty subjects were initially screened. All were aged over 70 years. After the exclusion of subjects who were illiterate, blind, etc., the results of 277 subjects were finally analyzed. Subjects with 6 years of education or less accounted for 92.42% of the total study sample. Twelve of them (5.33%) suffered from Alzheimer's disease, 7 from vascular dementia (2.52%) and 1 suffered from secondary dementia (0.36%).

RESULTS

MMSE exceeded 90% sensitivity at the level 22/23 and specificity at 14/15. The levels for CAMCOG were 56/57 and 43/44, respectively. This low performance of both tests is to a large extent due to the functional illiteracy of elderly individuals in Greece, to possible coexistence of mood disorders or simply to lack of cooperation. The analysis of data led to the development of an Epidemiological Dementia Index (EDI), with a scale ranging from 0 to 7. Nondemented subjects had a mean EDI of 5.12 (SD = 1.67) and demented patients had a mean EDI of 1.6 (SD = 1. 92). At the level 4/5 sensitivity was 93.33. Specificity was 93.56 at the level 2/3.
