[Alexithymia and Pathological Gambling: The Mediating Role of Difficulties in Emotion Regulation]. / Aleksitimi ve Patolojik Kumar: Duygu Düzenleme Güçlügünün Araci Rolü.

OBJECTIVE: The main objective was to determine the prediction level of alexithymia and difficulties in emotion regulation on pathological gambling. Secondly, this study aimed to examine the mediating role of difficulties in emotion regulation on the relationship between alexithymia and pathological gambling. METHOD: The sample was consisted of 246 male gamblers. The average age was 33.30 with a standard deviation of 11.62. In addition to socio-demographic form, The South Oaks Gambling Screen (SOGS), Toronto Alexithymia Scale (TAS-20) and Difficulties in Emotion Regulation Scale (DERS) were used to collect data. RESULTS: Regression analyses revealed that amount of money bet, total score of TAS-20 and DERS significantly predicted pathological gambling. In addition to these, difficulties in emotion regulation have a partial mediator role in the relationship between alexithymia and pathological gambling. CONCLUSION: It is argued that individuals high in alexithymia become prone to addiction behavior through emotion dysregulation. In addition to the alexithymia level, difficulties in emotion regulation are seen to play an important role in pathological gambling. In this context, this study contributes to the relevant literature by discussing alexithymia, emotion regulation and pathological gambling together.

Metabolic syndrome prevalence in different affective temperament profiles in bipolar-I disorder.

OBJECTIVE: Temperament originates in the brain structure, and individual differences are attributable to neural and physiological function differences. It has been suggested that temperament is associated with metabolic syndrome (MetS) markers, which may be partly mediated by lifestyle and socioeconomic status. Therefore, we aim to compare MetS prevalence between different affective temperamental profiles for each season in bipolar patients. METHODS: Twenty-six bipolar type-I patients of a specialized outpatient mood disorder unit were evaluated for MetS according to new definition proposed by the International Diabetes Federation in the four seasons of a year. Temperament was assessed using the Temperament Evaluation of Memphis, Pisa, Paris and San Diego - autoquestionnaire version (TEMPS-A). RESULTS: The proportions of MetS were 19.2, 23.1, 34.6, and 38.5% in the summer, fall, spring, and winter, respectively. Only depressive temperament scores were higher (p = 0.002) during the winter in patients with MetS. CONCLUSION: These data suggest that depressive temperament profiles may predispose an individual to the development of MetS in the winter.

Plasma concentrations of soluble cytokine receptors in euthymic bipolar patients with and without subsyndromal symptoms.

BACKGROUND: Current evidence suggests that high concentrations of pro-inflammatory markers are associated with bipolar disorder characterized by severe impairment during inter-episodic periods, reduced treatment response and persistent subsyndromal symptoms. We tested whether persistent subsyndromal symptoms in euthymic bipolar patients were associated with markers of an ongoing chronic pro-inflammatory process. METHODS: Forty-five euthymic bipolar patients (22 with subsyndromal symptoms (BD+) and 23 without subsyndromal symptoms (BD-) and 23 well controls (WC) were recruited for assessment of soluble tumor necrosis factor receptor-1 (sTNF-R1), soluble interleukin-6 receptor (sIL-6R) and soluble interleukin-2 receptor (sIL-2R) concentrations. Soluble cytokine receptor concentrations were assessed using enzyme-linked immunosorbent assay. RESULTS: In comparison to WC, sTNF-R1 concentration was higher in both BD- and BD+ (age and sex adjusted standardized ß, respectively: ß = 0.34, p = 0.012 and ß = 0.41, p = 0.003). Similarly, compared to WC, sIL-6R concentration was higher in both BD- and BD+ (age and sex adjusted standardized ß, respectively: ß = 0.44, p = 0.001 and ß = 0.37, p = 0.008). There was no difference between BD- and BD+ in the concentration of either sTNF-R1 or sIL-6R; plasma concentration of sIL-2R was not analyzed as 75% percent of the samples were non-detectable. CONCLUSIONS: Although bipolar patients present with a pro-inflammatory shift compared to well controls, subsyndromal symptoms are not associated with additive increasing effects. Longitudinal studies with larger samples are required to clarify the relationship between illness course and inflammatory markers in bipolar disorder.

Evidence for an association between tumor necrosis factor-alpha levels and lithium response.

BACKGROUND: The role of inflammation in bipolar disorder has recently emerged as a potential pathophysiological mechanism. Tumor necrosis factor-alpha (TNF-α) modulation may represent a pathogenic molecular target and a biomarker for staging bipolar disorder. In this context, the possible association between lithium response and TNF-α level was examined. METHODS: Sixty euthymic bipolar patients receiving lithium therapy were recruited for assessment of TNF-α level. The ALDA lithium response scale (LRS) was used to evaluate longitudinal lithium response in bipolar patients, using cut-offs of poor response, partial response and good response. TNF-α level was assessed using enzyme-linked immunosorbent assay. RESULTS: There was a significant increase in TNF-α level in patients with poor lithium response compared to those with good response, also after controlling for a range of potential confounders (adjusted effect size: 0.47, p=0.011). Partial response showed a directionally similar, but attenuated and statistically inconclusive association (adjusted effect size: 0.16, p=0.326). LIMITATIONS: Assessment of response was retrospective and natural course cannot be separated easily from treatment response in an observational design. Selection of additional inflammatory markers could provide for a better understanding of underlying immune changes. CONCLUSIONS: This study strengthens the hypothesis that TNF-α level may mark or mediate lithium response, and that continuous immune imbalance in poor lithium responders may occasion treatment resistance. Further investigation of immune alterations in treatment-resistant bipolar patients may be productive.

Adherence to Turkish psychiatric association guideline for bipolar depression treatment in a specialized mood disorders outpatient unit.

BACKGROUND: Bipolar patients spend up to one third of their lives in depression however, acute treatment guidelines mainly focused on the manic phase of illness. With recent attention to the importance of evidence-based medicine in psychiatry, a number of treatment guidelines have emerged to aid clinicians in clinical decision making. Here, we aim to measure concordance with the Turkish Psychiatric Association Treatment Guideline for Bipolar Disorders (TPATGBD) for the depressive phase of illness. SUBJECTS AND METHODS: Bipolar patients attending the Rasit Tahsin Mood Disorders Outpatient Unit of Istanbul Bakirköy Research and Training Hospital for Psychiatry, Neurolgy & Neurosurgery, were assessed using standardized forms based on a nation-wide mood disorders follow-up program. Concordance of implementations with the TPATGBD were evaluated step by step for each level of depression severity. RESULTS: Concordance rates with the first step recommendations of the guideline were 29.4%, 27.4% and 87.5% for mild-moderate, moderate-severe (without psychosis) and severe depression (with psychosis), respectively. Concordance rates with the second step recommendations of the guideline were lower for bipolar depressions without psychosis. Overall, adherence to the guideline did not impact on time to remission (p=0.19). CONCLUSIONS: Despite considerable efforts to develop and disseminate evidence-based guidelines, they are not widely followed by clinicians and important opportunities clearly exist to educate clinicians about the feasibility and utility of clinical guidelines for bipolar disorder. Systematic studies in the future are required to clarify our understanding of clinicians' attitudes to the use of guidelines and to explain the discrepancy between guidelines and clinical practice.

A survey of verbal and physical assaults towards psychiatrists in Turkey.

BACKGROUND: Assaults on health professionals have been an area of burgeoning clinical and political interest in recent years. There is now a body of literature suggesting that violence towards psychiatrists is more common than to other doctors. Thus far the vast majority of research in this area has been conducted in Western European and North American clinical settings. For the first time, this study examines this issue in the context of Turkish psychiatric settings. OBJECTIVE: (i) The study aims to detect the prevalence of verbal and physical assaults towards psychiatrists in Turkey. (ii) It aims to compare the experience of verbal and physical assaults according to the gender and training experience of psychiatrists. (iii) The paper intends to investigate how psychiatrists reacted to and appraised the experience of violence. METHODS: A questionnaire was prepared to evaluate violence towards psychiatrists (adapted from the Overt Agression Scale). The questionaire was administered to psychiatric specialists and residents working in state hospitals, research and training hospitals, mental health hospitals and university psychiatry clinics. A response rate of 93% was achieved with 186 out of 200 psychiatrsits approached completing the study questionnaire. RESULTS: Of all the psychiatrists who responded, 71% reported having experienced verbal or physical assaults during their professional life (verbal assaults only (19.9%), physical assaults only (2.7%) and both (48.4%)). Of these, 26% suffered injury to at least a mild degree. There was no statistically significant difference in terms of gender and workplace. In spite of the extremely high rates of aggression and violence towards psychiatrists, roughly 50% perceived these acts a normal part of their job and only 5% formally reported the violent incident. CONCLUSION: The majority of psychiatrists described having been victims of verbal and physical assaults although half perceived aggression and violence as a normal part of their job. Levels of reporting of violence were very low in the context of this study. Studies such as this provide evidence to inform the development of improved management of violence and may encourage psychiatrists to report violence.

Cytokine levels in euthymic bipolar patients.

BACKGROUND: The pathophysiology of bipolar disorder is not thoroughly understood. Several studies have investigated the possible role of cytokines in psychiatric disorders, based on their role in neuro-immune modulation; however, findings in studies on bipolar disorder remain limited and contradictory, and most studies have focused on either manic or depressive episodes. These studies suggest that both manic and depressive episodes could be pro-inflammatory states. The present study aimed to determine whether there are enduring differences in cytokine levels-unrelated to the effects of medication-between euthymic bipolar patients and healthy controls. METHODS: The study included 31 euthymic bipolar patients-16 medication-free (MF) and 15 on lithium monotherapy (LM) and 16 healthy volunteers in whom serum cytokine levels were measured. The 3 groups were homogenous in terms of age, gender, and ethnicity. IFN-γ, TNF-α, IL-2, IL-4, IL-5, and IL-10 levels were measured in all groups using flow cytometry. RESULTS: There were no differences in cytokine levels between MF euthymic bipolar patients and healthy controls. TNF-α and IL-4 levels in LM euthymic bipolar patients were higher than in both the MF euthymic bipolar patients and controls. LIMITATIONS: The small and strictly selected study sample could limit the generalizability of the findings. CONCLUSIONS: Cytokine production in MF euthymic bipolar patients was similar to that in healthy controls. The present study shows that the pro-inflammatory state resolves in euthymia and that lithium had an influence on the cytokine profile, which could create a confounding factor while investigating disease- related immunopathology of bipolar disorder.

[Attitudes and behaviors of psychiatry residents and psychiatrists working in training institutes towards the relationship between the pharmaceutical industry and physicians]. / Egitim Veren Kurumlarda Calisan Psikiyatristlerin.

OBJECTIVE: To determine the attitudes and behaviors of psychiatrists and psychiatry residents towards pharmaceutical representatives and their promotional activities, and to evaluate the effect of the duration of residency and type of the training institution on these attitudes and behaviors. METHOD: A validated questionnaire for assessing the attitudes and behaviors of physicians towards the pharmaceutical industry was administered to psychiatrists and psychiatry residents at regional meetings. Of the 1973 participants, 348 responded. RESULTS: Although there was significant interaction between psychiatrists and pharmaceutical representatives, 50.7% of psychiatrists reported that they thought these interactions had no impact on their prescribing practices. First- and second-year residents agreed more than the other residents and the specialist that pharmaceutical representatives provided accurate information and had no effect on physician prescribing practices. First- and second-years residents agreed less than older residents that pharmaceutical representatives used marketing techniques. The psychiatrists regarded most of the pharmaceutical promotions as appropriate. State hospital staff agreed more than the university hospital staff that the pharmaceutical industry should support educational meetings in their institutions. CONCLUSION: There was intense interaction (3/4)characterized by undefined boundaries (3/4)between psychiatrists and the pharmaceutical industry. Most physicians were not provided any guidelines concerning their interactions with pharmaceutical representatives and there was general concern about the necessity of restricting these interactions.

[Genetic studies of bipolar disorder: a review]. / Bipolar Bozuklukla Ilgili Genetik Arastirmalar: Bir Gözden Geçirme.

Bipolar disorder is a severe mental illness that afflicts approximately 1% of the world's population, and is characterized by mood swings from elation to depression. Although the etiology of bipolar disorder remains unclear, heritable factors have been shown to be involved. Family, twin, and adoption studies suggest a genetic etiology. Molecular genetic studies also support a genetic component. Many chromosomal regions have been implicated by these molecular genetic studies, but no single susceptibility gene has been identified. These findings show that bipolar disorder has a complex genetic etiology in which multiple unidentified genes and environmental factors play an important role in its pathogenesis. Herein, molecular genetic studies of bipolar disorder are reviewed based on a search of Medline using the key words, bipolar, genetic, and chromosome. Studies with positive results for bipolar disorder were selected first. The findings from these molecular genetic studies are reviewed systematically, chromosome by chromosome. Causes of the differences between the reported findings and of non-replication are discussed. Finally, important factors for designing a genetic study of bipolar disorder are examined.

Electroconvulsive therapy in psychiatric practice: a selective review of the evidence.

Electroconvulsive therapy (ECT) is largely historical but is still in use. Modern psychiatry requires careful selection of patients in whom ECT will be performed. The indications for ECT treatment are limited, and the selection criteria should be strictly followed. The advantages and the disadvantages of the methods are discussed here. Despite the limitations, ECT seems to have real value in selected mental conditions in which it can even be considered a life-saving procedure.

[Development of a questionnaire to assess inter-episode functioning in bipolar disorder: Bipolar Disorder Functioning Questionnaire]. / Bipolar Bozuklukta Islevsellik Olçeginin Gelistirilmesi, Güvenilirlik ve Geçerliligi.

OBJECTIVE: Even though quality of life and functioning are topics that are point of interest, they are not assessed adequately in mood disorders. In this study, it is aimed to develop a functioning assessment scale in bipolar disorder. METHOD: Bipolar Disorder Functioning Questionnaire (BDFQ) is developed by the Scientific Section for Mood Disorders of the Psychiatric Association of Turkey. The questionnaire contains 58 items, and consists of eleven subscales: emotional functioning, intellectual functioning, sexual functioning, feelings of stigmatization, social withdrawal, household relations, relations with friends, participation to social activities, daily activities and hobbies, taking initiative and self sufficiency, and occupation. RESULTS: In this study, 252 remitted bipolar patients from 15 centers were included. In addition, thirty subjects without any lifetime psychiatric, neurological or physical disease were recruited. The mean age of the patients was 38.6+/-12.1 and 56% (n=141) were female. The mean duration of the bipolar disorder was 11.9+/-9.2 years, and 91.3% of the patients were diagnosed to have bipolar I disorder. In the reliability analyses, after the exclusion of six items with low reliability coefficients, The Cronbach alpha coefficient was calculated to be 0.91. The item-total scale correlations were between 0.22-0.86. In test-retest reliability, the correlation between the two ratings was high (r=0.82, p<0.0001). In validity analyses, 13 factors were obtained representing 65.1% of the total variance in exploratory factor analysis. In confirmatory factor analysis, 11 domains fit the model with a RMSEA of 0.061. BDFQ significantly correlated with GAF (r=0.428, p<.0001). BDFQ also showed significantly negative correlation with HAM-D (r=-0.541, p<0.0001) and YMRS (r=-0.365, p<0.0001). It discriminated the patients (mean score=111.8+/-15.2) from the healthy subjects (mean score=121.4+/-10.4) well (t=-2.300, p=0.038). CONCLUSION: With the six items excluded, it is suggested that the 52-item BDFQ is a reliable and valid instrument in the assessment of functioning in bipolar disorder.

Stigmatization in the long-term treatment of psychotic disorders.

Stigma is linked to negative prejudices without examining whether there is any justification for such behaviour. Over time, various efforts have been made to reduce prejudice toward people with mental illness. Yet, the World Health Organization (WHO) World Health Report still describes stigma as one of the greatest obstacles to the treatment of mental illness. While schizophrenia, among other mental illnesses, is the most stigmatized even to the point that some want the name of the illness to be hidden or changed, patients with bipolar illness may also be exposed to stigma. The degree of stigmatization has been found to be positively associated with the severity of the mental disorder, and stigma is carried out not only by patients but also by their families in correlation with the severity. Tragically, people with mental illness themselves are as negative in their opinions about mental illness as is the general public, and concerns about stigma adversely affect self-esteem and adaptive social functioning. There are many programmes worldwide for the fight against stigmatization, and there is clear recognition of the fact that stigma can only be successfully eliminated if the programme becomes a normal part of health service rather than of campaigns of limited duration.

Atypical antipsychotics related metabolic syndrome in bipolar patients.

BACKGROUND: This is the first study in bipolar patients, aimed to evaluate possible roles of the drugs, [atypical antipsychotics (AA) and mood stabilizers (MS)], inducing metabolic syndrome (MetS). METHODS: 125 bipolar patients, diagnosed according to the DSM IV, were assessed cross-sectionally for MetS according to the National Cholesterol Educational Program criteria (NCEP ATP III). Patients included in the study were required to receive medications (AAs: quetiapine, risperidone and olanzapine, and MSs: Lithium, Sodium Valproate, Carbamazepine, Lamotrigine) for at least 3 months. Patients are divided into three groups as only AA users, AA+MS users and only MS users. RESULTS: Of the patients, 32% were MetS, a proportion higher than normal population and similar as previous studies in bipolar patients. AA taking patients had significantly higher MetS rates than the others (chi(2)=10.47 df=2 p=0.005). Also, AA taking patients had significantly higher MetS rates than MS taking patients (chi(2)=8.86 df=1 p=0.003). There was no significant difference among quetiapine, olanzapine, risperidone usage for MetS prevalences (chi(2)=0.38 df=2 p=0.82). CONCLUSIONS: AA taking bipolar patients had higher MetS rates. Despite already existing data on MetS and antipsychotics, this cross-sectional study is the first research, discusses AAs and MSs for inducing MetS in bipolar disorder. Prospectively designed researches should be conducted for further clarification of the role of these drugs in MetS.

[Reliability and validity of the schedule for deficit syndrome in schizophrenia]. / Sizofreni'de Eksiklik Sendromu Cizelgesi (ESC)'nin Güvenilirlik ve Geçerlik Calismasi.

OBJECTIVE: The Schedule for Deficit Syndrome (SDS) is an instrument for categorizing schizophrenic patients as those with and without deficit syndrome. This schedule has been translated and adapted into the Turkish language in order to study its reliability and validity. METHOD: 30 male schizophrenic patients were included in the study. The patients had been ill for a long period of time and the course was continuous. The patients were assessed by two different raters using the SDS as a means of testing its reliability. A third rater assessed the same group of patients using the BPRS to test the validity of the SDS. RESULTS: The raters using the SDS demonstrated good inter-rater reliability for the categorization of patients with and without deficit syndrome, as well as for rating global severity (kappa: 0.88-0.93) and individual negative symptoms (kappa: 0.51-0.61). The schedule was also found to have a high validity for both categorization and measuring individual negative symptoms. (U: 60.0, P: 0.03). CONCLUSION: The results demonstrated that the Turkish version of the SDS would be a reliable and valid instrument that could be used in the study of schizophrenia.

Bipolar depression: an overview.

Depressive episodes are significant in bipolar illness since patients can spend up to one-third of their lives in depression. Although the treatment of bipolar depression remains an understudied area, new data from randomized, controlled trials and naturalistic studies have expanded the range of treatments available. The main aim in the treatment of bipolar depression is the prevention of the patient switching to mania and cycle acceleration, and antidepressant therapy may be contraindicated because of the risk for switching. Guidelines for the acute treatment of bipolar depression emphasize treatment with a mood stabilizer, of which lithium has been the most thoroughly studied in randomized, controlled trials in acute bipolar depression. Lamotrigine has also demonstrated significant efficacy in recent studies and has been approved by the FDA.
