Assessment of dissociation among combat-exposed soldiers with and without posttraumatic stress disorder.

BACKGROUND: Dissociation is a disruption of and/or discontinuity in the normal, subjective integration of one or more aspects of psychological functioning, including memory, identity, consciousness, perception, and motor control. A limited number of studies investigated combat-related dissociation. OBJECTIVE: The primary aim of this study was to evaluate the relationship between dissociative symptoms and combat-related trauma. METHOD: This study included 184 individuals, including 84 patients who were exposed to combat and diagnosed with posttraumatic stress disorder (PTSD) (Group I), 50 subjects who were exposed to combat but were not diagnosed with PTSD (Group II), and 50 healthy subjects without combat exposure (Group III). The participants were evaluated using the Dissociative Experiences Scale (DES) to determine their total and sub-factor (i.e., amnesia, depersonalization/derealization, and absorption) dissociative symptom levels. In addition, Group I and Group II were compared with respect to the relationship between physical injury and DES scores. RESULTS: The mean DES scores (i.e., total and sub-factors) of Group I were higher than those of Group II (p<0.001), and Group II's mean DES scores (i.e., total and sub-factors) were higher than those of Group III (p<0.001). Similarly, the number of subjects with high total DES scores (i.e.,>30) was highest in Group I, followed by Group II and Group III. When we compared combat-exposed subjects with high total DES scores, Group I had higher scores than Group II. In contrast, no relationship between the presence of bodily injury and total DES scores could be demonstrated. In addition, our results demonstrated that high depersonalization/derealization factor scores were correlated with bodily injury in PTSD patients. A similar relationship was found between high absorption factor scores and bodily injury for Group II. CONCLUSIONS: Our results demonstrated that the level of dissociation was significantly higher in subjects with combat-related PTSD than in subjects without combat-related PTSD. In addition, combat-exposed subjects without PTSD also had higher dissociation levels than healthy subjects without combat experience.

Effects of electroconvulsive therapy on serum levels of brain-derived neurotrophic factor and nerve growth factor in treatment resistant major depression.

OBJECTIVES: This study aimed to investigate the effects of electroconvulsive treatment on serum BDNF and NGF levels in patients with treatment-resistant major depression. METHODS: Thirty patients with treatment-resistant major depression and 30 healthy controls were included in the study. The patients' serum BDNF and NGF levels were measured three times; before treatment (T0), when the clinical response occurred (T1) and at the end of treatment (T2). RESULTS: The reduction detected in the HAM-D scores with ECT during the T0-T1, T1-T2 and T0-T2 periods was found to be statistically significant. In the patient group, increase in the mean BDNF levels after ECT treatment was found to be statistically significant (p<0.05). Significant increases in serum BDNF levels with ECT were lower than in the control group, and the serum NGF levels did not increase significantly. There was no relationship between the severity of the depression and serum BDNF and NGF levels (p>0.05). CONCLUSIONS: This study evaluated the role of neurotrophic factors in the etiopathogenesis of major depression. Future studies should investigate the relationship between neurotrophic factors with neuroendocrine and genetic processes to elucidate the psychobiology and treatment of mental disorders.

Is transcranial magnetic stimulation effective in treatment-resistant combat related posttraumatic stress disorder?

OBJECTIVE: To examine the effectiveness of repetitive transcranial magnetic stimulation (rTMS) in patients with treatment-resistant posttraumatic stress disorder (PTSD) with co-occurring major depression. METHODS: We examined data on 20 male combat related PTSD patients admitted to the Post Traumatic Stress Disorder Clinic of Gülhane Military Medical Academy, Ankara, Turkey between January 2011 and December 2012 that received rTMS in addition to medical therapy. We obtained the data by examining the case files and hospital computer records. RESULTS: Decreases in the Impact of Event Scale (IES) hyperarousal scores were statistically significant. However, there were no statistically significant differences between the total IES scores, IES intrusion scores, IES avoidance scores, Beck Depression Inventory, and Beck Anxiety Inventory scores before and after rTMS treatment. CONCLUSION: The efficacy of rTMS on the hyperarousal symptoms indicated that rTMS could be used in the treatment of patients with treatment-resistant PTSD. The role of rTMS in the clinical management of PTSD should be identified in further comprehensive studies.

Effect of propofol versus sodium thiopental on electroconvulsive therapy in major depressive disorder: a randomized double-blind controlled clinical trial.

OBJECTIVES: To compare propofol and sodium thiopental as anesthetic agents for electroconvulsive therapy (ECT) in major depression with respect to clinical effect. METHODS: Participants were composed of 96 patients with depression who were administered either propofol or sodium thiopental as an anesthetic agent for bilateral ECT. The Hamilton Depression Rating Scale was administered at baseline and after 6 treatments. Algorithm-based charge dosing was used. RESULTS: There was a statistically significant difference between the groups regarding postintervention Hamilton Depression Rating Scale score. The preintervention mean (SD) scores in the propofol group and the sodium thiopental group were 37.3 (2.2) and 36.7 (1.2), respectively. The postintervention mean (SD) scores in the propofol group and the sodium thiopental group were 10.7 (1.8) and 13.4 (3.3), respectively. No correlation was found between clinical response and age, weight, and body mass index. There was no association between the groups' seizure time and duration of recovery. CONCLUSIONS: In conclusion, propofol may improve major depressive disorder more than sodium thiopental in patients who are receiving ECT.

Plasma asymmetric dimethylarginine (ADMA) concentrations in patients with first and multiple episode schizophrenia.

An increasing number of reports in the literature indicate that asymmetric dimethylarginine (ADMA) regulates nitric oxide generation in numerous disease states. ADMA has been less studied in psychiatric disorders. The purpose of this study was to determine plasma ADMA concentrations in patients with schizophrenia compared to healthy controls. The study was conducted in 49 male patients with schizophrenia and 30 healthy male control subjects. The patient group was 24 first episode and 25 multiple episode schizophrenia participants. All schizophrenic patients were administered the Scale for the Assessment of Negative Symptoms, the Scale for the Assessment of Positive Symptoms (SAPS) and the Brief Psychiatric Rating Scale. Measurement of plasma concentrations of ADMA was accomplished by HPLC. There was a significant increase in the plasma ADMA concentrations in patients with schizophrenia when compared to healthy controls. There were no significant correlations between the plasma concentrations of ADMA and scores of psychiatric rating scales. In the multiple episode schizophrenia subgroup, the mean plasma ADMA concentration was significantly higher than in the first episode schizophrenia subgroup. The study indicate that plasma ADMA concentrations in patients with schizophrenia are elevated.

Serum haptoglobin levels in patients with melancholic and nonmelancholic major depression.

BACKGROUND: Major depression (MD) is accompanied by systemic immune activation or an inflammatory response with the involvement of phagocytic cells, T cell activation, B cell proliferation, and an acute phase response with increased levels of positive and decreased levels of negative acute-phase proteins. In this study, we aimed to determine any differences in serum haptoglobin (Hp) concentrations among patients with melancholic and nonmelancholic MD and the healthy controls. METHODS: This study involved 125 male patients who were admitted to the Department of Psychiatry, Gulhane Military Medical Academy (GMMA), in Ankara, Turkey. They were diagnosed with MD according to the Diagnostic and Statistical Manual of Mental Disorders (DSM-IV) and agreed to participate in the study. The melancholic group consisted of 37 patients and the nonmelancholic group had 45 patients. A healthy control group of 40 subjects was selected from the staff of GMMA. These subjects had not had any lifetime psychiatric diagnosis or psychiatric treatment in their medical histories. Peripheral venous blood samples were obtained from the patients and the control group for a complete blood count, routine biochemistry, and the detection of serum Hp levels. RESULTS: There was no statistically significant difference among the melancholic MD, the nonmelancholic MD, and the healthy control groups in terms of age, level of education, and gender. Serum Hp concentrations are significantly higher in melancholic patients as compared with non-melancholic depressed patients and controls. However, there was no statistically significant difference between the nonmelancholic MD and the control group in terms of Hp concentrations. CONCLUSION: The results of this study are important in terms of showing different serum Hp concentrations in patients with melancholic and nonmelancholic MD.

Relief by electroconvulsive therapy for postsurgical delirium in malignant catatonia.

We report a 46-year-old man who was successfully treated with electroconvulsive therapy for neuroleptic malignant syndrome that developed during the course of delirium after cardiac surgery. We suggest that electroconvulsive therapy be considered as a reasonable treatment alternative for relevant cases.

Aripiprazole as an augmentation agent in treatment-resistant body dysmorphic disorder.

Body dysmorphic disorder (BDD) is a relatively common and severe disorder for which pharmacotherapy has been only minimally studied. BDD often appears to respond to selective serotonin reuptake inhibitors (SSRIs), but many patients do not respond or respond only partially. Investigation of SSRI augmentation strategies is therefore needed. We report a case of treatment-resistant BDD that was successfully treated with pharmacological augmentation of fluvoxamine with aripiprazole. The patient, a 43-year-old woman, had been taking a stable dose of fluvoxamine (400 mg/day) for 6 months when she was started on aripiprazole (10 mg/day). After 10 weeks of this treatment, her clinical condition improved markedly, as indicated by a significant decrease in the Body Dysmorphic Disorder Examination score. This case presents some preliminary evidence that addition of the atypical antipsychotic agent aripiprazole may be useful in patients with treatment-resistant BDD. However, results from controlled studies are needed to support this finding.

The association between serum levels of neopterin and number of depressive episodes of major depression.

BACKGROUND: There is an interaction between the immune system and the central nervous system by means of hormones, peptides, and neurotransmitters. The aims of the present study were to determine whether the serum neopterin levels in patients with major depression (MD) differ from a healthy control group and to investigate the relationship between previous MD episodes and serum neopterin levels. METHODS: Thirty patients who were admitted to the GATA Psychiatry Outpatient Clinics and were diagnosed with MD according to DSM-IV, and who agreed to participate in the study, were included in the study. Twenty-six healthy volunteers matched for age, gender, and level of education who agreed to participate in the study were served as controls. Peripheral venous blood samples were obtained from the patients and the control group for complete blood count, routine biochemistry, and the detection of serum neopterin levels. The analyses were performed in the laboratory of the GATA Department of Biochemistry. RESULTS: There was no significant difference between the MD group and the healthy controls with respect to age, level of education, smoking, and gender. Serum neopterin levels of the MD group who had experienced two or more episodes were higher than the first-episode group and the control group. Age of onset and the number of previous episodes had an independent impact on serum neopterin levels in MD patients, while smoking did not show any effect. CONCLUSION: In the present study, the neopterin levels of patients who had experienced two or more episodes were higher than the first-episode depressive group and healthy control group. It was also found that the number of previous depressive episodes and the ages of the MD cases had an independent effect on serum neopterin levels.

Thorax deformity, joint hypermobility, and anxiety disorders.

OBJECTIVE: To evaluate the association between thorax deformities, panic disorder, and joint hypermobility METHODS: The study includes 52 males diagnosed with thorax deformity, and 40 healthy male controls without thorax deformity, in Tatvan Bitlis and Isparta, Turkey. The study was carried out from 2004 to 2006. The teleradiographic and thoracic lateral images of the subjects were evaluated to obtain the Beighton scores; subjects' psychiatric conditions were evaluated using the Structured Clinical Interview for DSM-IV Axis I Disorders (SCID-1), and the Hamilton Anxiety Scale (HAM-A) was applied in order to determine the anxiety levels. Both the subjects and controls were compared in sociodemographic, anxiety levels, and joint mobility levels. In addition, males with joint hypermobility and thorax deformity were compared to the group with thorax deformity without joint hypermobility. RESULTS: A significant difference in HAM-A scores was found between the groups with thorax deformity and without. In addition, 21 subjects with thorax deformity met the joint hypermobility criteria in the group with thorax deformity, and 7 subjects without thorax deformity met the joint hypermobility criteria in the group without thorax deformity, according to Beighton scoring. The Beighton scores of the subjects with thorax deformity were significantly different from those of the group without deformity. Additionally, anxiety scores of the males with thorax deformity and joint hypermobility were found higher than males with thorax deformity without joint hypermobility. CONCLUSION: Anxiety disorders, particularly panic disorder, have a significantly higher distribution in male subjects with thorax deformity compared to the healthy control group. In addition, the anxiety level of males with thorax deformity and joint hypermobility is higher than males with thorax deformity without joint hypermobility.

Screening disordered eating attitudes and eating disorders in a sample of Turkish female college students.

It has been hypothesized that college women are particularly susceptible to the development and maintenance of disturbed eating behaviors. The purpose of this study was to determine the frequency of disordered eating attitudes and eating disorders in a sample of Turkish female college students. The Eating Attitudes Test was administered to a sample of 414 female college students. The subjects who had a score of 30 or higher were accepted as having disordered eating attitudes, and all of them have been examined using the Structured Clinical Interview for Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition for eating disorders. Of the overall sample, 17.1% of subjects were classified as having disordered eating attitudes. This subgroup of subjects was then compared with the remainder on all the other measures. The differences between students with disordered eating attitudes and those without on sociodemographic variables (except for age) were not statistically significant. The rate was 1% for eating disorders including anorexia nervosa (0.5%) and bulimia nervosa (0.5%). This study suggested that the prevalences of disordered eating attitudes and anorexia nervosa among female college students in Turkey were similar to those found in Western societies, but the rate for bulimia nervosa was lower compared with Western societies.
