Abstract
BACKGROUND Schizophrenia is a chronic and debilitating disorder, the etiology of which remains unclear. Apoptosis is a programmed cell death mechanism that might be implicated in neuropsychiatric disorders, including schizophrenia. In this study, we aimed to compare the serum levels of apoptosis among deficit schizophrenia (DS) syndrome patients, nondeficit schizophrenia (NDS) patients, and healthy controls (HCs). PATIENTS AND METHODS After the inclusion and exclusion criteria were applied, 23 DS patients, 46 NDS patients, and 33 HCs were included in the study. The serum apoptosis levels were measured using a quantitative sandwich enzyme immunoassay with human monoclonal antibodies directed against DNA and histones. RESULTS There was a significant difference among the three groups in terms of the levels of apoptosis (F 2,96=16.58; P<0.001). The serum apoptosis levels in the DS and NDS groups were significantly higher than those in the HC group. Furthermore, the serum apoptosis levels in the DS group were significantly higher than the levels in the NDS group. CONCLUSION This study suggests that increased levels of apoptosis may be implicated in the pathophysiology of DS syndrome. However, further studies are needed to support the role of apoptosis in DS.

Abstract
BACKGROUND Brain-derived neurotrophic factor (BDNF) is a well-established neurotrophin that plays a role in the pathophysiology of numerous psychiatric disorders. Many studies have investigated the serum BDNF levels in patients with schizophrenia. However, there are restricted data in the literature that compare the serum BDNF levels in patients with deficit and nondeficit syndromes. In this study, we aimed to compare the serum BDNF levels between schizophrenic patients with deficit or nondeficit syndrome and healthy controls. METHODS After fulfilling the inclusion and exclusion criteria, 58 patients with schizophrenia and 36 healthy controls were included in the study. The patients were grouped as deficit syndrome (N=23) and nondeficit syndrome (N=35) according to the Schedule for the Deficit Syndrome. Three groups were compared in terms of the sociodemographic and clinical variants and serum BDNF levels. RESULTS The groups were similar in terms of age, sex, body mass index, and smoking status. The serum BDNF levels in patients with deficit syndrome were significantly lower than those in healthy controls. In contrast, the serum BDNF levels in patients with nondeficit syndrome were similar to those in healthy controls. CONCLUSION This study suggests that decreased BDNF levels may play a role in the pathophysiology of schizophrenic patients with deficit syndrome. Nonetheless, additional studies using a larger patient sample size are needed to investigate the serum BDNF levels in schizophrenic patients with deficit syndrome.

Abstract
BACKGROUND Schizophrenia is a chronic, disabling, disorder that affects approximately 1% of the population. The nature of schizophrenia is heterogeneous, and unsuccessful efforts to subtype this disorder have been made. Deficit syndrome schizophrenia (DS) is a clinical diagnosis that has not been placed in main diagnostic manuals. In this study, we aimed to investigate and compare neurological soft signs (NSS) in DS patients, non-deficit schizophrenia (NDS) patients, and healthy controls (HCs). We suggest that NSS might be an endophenotype candidate for DS patients. METHODS Sixty-six patients with schizophrenia and 30 HCs were enrolled in accordance with our inclusion and exclusion criteria. The patients were sub-typed as DS (n=24) and NDS (n=42) according to the Schedule for the Deficit Syndrome. The three groups were compared in terms of sociodemographic and clinical variables and total scores and subscores on the Physical and Neurological Examination for Soft Signs (PANESS). Following the comparison, a regression analysis was performed for predictability of total PANESS score and its subscales in the diagnosis of DS and NDS. RESULTS The groups were similar in terms of age, sex, and smoking status. The results of our study indicated that the total PANESS score was significantly higher in the DS group compared to the NDS and HC groups, and all PANESS subscales were significantly higher in the DS group than in the HC group. The diagnosis of DS was predicted significantly by total PANESS score (P<0.001, odds ratio =9.48, 95% confidence interval: 0.00-4.56); the synergy, graphesthesia, stereognosis, motor tasks, and ability to maintain posture subscales were found to be significant predictors. CONCLUSION This study confirms that NSS were higher in patients with DS. In addition, we suggest that our results might support the notion of DS as a different and distinct type of schizophrenia. NSS might also be a promising candidate as an endophenotype for DS. However, large sampled, multicentric studies are needed to clarify the place of NSS as an endophenotype in DS.

Abstract
PURPOSE Vitiligo is an acquired pigmentary skin disease that can cause serious cosmetic problems. There have been numerous and well established studies that have demonstrated the comorbidity of various psychiatric disorders in patients with vitiligo. However, to our knowledge, there have been no studies investigating whether a psychiatric biomarker, such as brain-derived neurotrophic factor (BDNF), is associated with vitiligo. PATIENTS AND METHODS This study was conducted in Namık Kemal University Medical Faculty, Departments of Dermatology and Psychiatry between January 2013 and September 2014. After meeting inclusion and exclusion criteria, serum BDNF levels were assayed in 57 patients with first onset vitiligo and no known current or past psychiatric disorder and compared with BDNF levels in 58 age and sex matched healthy subjects. RESULTS The age and female/male ratios were similar between groups. The mean values of serum BDNF were 1.57±0.97 ng/dL and 2.37±1.73 ng/dL in the vitiligo group and in the healthy control group, respectively. The mean BDNF level was significantly higher in the healthy control group compared with the vitiligo group (t=2.76, P=0.007). CONCLUSION This is the first study to compare serum BDNF levels between patients with vitiligo and healthy subjects. The reduced level of serum BDNF in patients with vitiligo may be directly related to the etiology of vitiligo or associated with the high percentage of psychiatric disorders in that patient population. Further studies are needed to support our preliminary results.

Abstract
BACKGROUND Second generation antipsychotics (SGAs) are currently the most prescribed drugs in the treatment of schizophrenia. Despite their advantages, which include greater improvement in negative symptoms, cognitive function, prevention of deterioration, quality of life, and fewer extrapyramidal symptoms, the concern regarding metabolic abnormalities which might cause cardiovascular diseases during treatment with SGAs have been rising. Paraoxonase 1 (PON1) is an enzyme mostly located on high-density lipoprotein particles, and has been shown to protect or inhibit lipoprotein oxidation. Growing evidence suggests that PON1 plays a key role in the pathophysiology of atherosclerosis. METHODS In the present study, we measured serum PON1 activity and serum levels of total cholesterol (TC), triglyceride, high-density lipoprotein cholesterol (HDL-C), and low-density lipoprotein cholesterol (LDL-C) in patients with schizophrenia, who had been treated with either olanzapine or quetiapine, and in healthy controls. Thirty five patients who had been treated with olanzapine, 29 patients who had been treated with quetiapine, and 32 age, sex, and smoking status-matched healthy control (HC) participants were enrolled. Serum PON1 activity and serum levels of TC, triglyceride, HDL-C, and LDL-C were measured. RESULTS Serum PON1 activity in the olanzapine group was significantly lower than that of HC and quetiapine groups. Furthermore, serum levels of TC and LDL-C in the olanzapine group were significantly higher than those of quetiapine and HC groups. Interestingly, there was a positive correlation between PON1 activity and HDL-C levels in the olanzapine group. CONCLUSION These findings suggest that serum PON1 activity in patients treated with olanzapine was lower than that of HC and quetiapine groups, and that PON1 may play a role in the metabolic side effects associated with olanzapine treatment. A further study to examine the relationship between serum PON1 activity and cardiovascular and metabolic side effects during treatment with SGAs will be of great interest.

Abstract
Hyperprolactinemia, an adverse side-effect of the use of typical and some atypical antipsychotics, has both acute and chronic clinical consequences. When observed in schizophrenic patients, it may be treated by switching the patient to an antipsychotic agent with a lower liability for the induction of hyperprolactinemia. The effects of substituting aripiprazole for other antipsychotic agents on schizophrenic patients with antipsychotic-induced hyperprolactinemia have been previously reported in several studies. Many studies have also noted that aripiprazole can sometimes lead to increases in psychotic symptoms, especially in the period immediately following the switch or when aripiprazole is combined with a dopamine antagonist. Here, we report observations on five female patients who were experiencing symptomatic hyperprolactinemia and psychotic exacerbation while on antipsychotic treatment, yet improved in both conditions after being switched to aripiprazole monotherapy. We also provide a brief review of the existing studies that report the results of switching patients from other antipsychotics to aripiprazole.

Abstract
Rabbit syndrome (RS) is a rare side effect of prolonged neuroleptic administration characterised by rapid, fine, rhythmic movements of the mouth along a vertical axis. Long-term exposure to the first generation neuroleptics has clearly been associated with RS, but little is known regarding the risk of RS because of the exposure to the newer atypical antipsychotics. Aripiprazole is a new dopaminergic agent and has been reported to be clinically useful as an antipsychotic drug with reduced extrapyramidal motor side effects. In addition, there are some case reports concerning extrapyramidal side effects, which include tardive dyskinesia, parkinsonism and RS associated with aripiprazole. We present the case of a patient who developed RS during treatment with aripiprazole. Potential mechanisms, including D2 receptor occupancy, low anticholinergic properties and dopamine hypersensitivity theory, are discussed. Although studies with aripiprazole have shown a low liability for extrapyramidal side effects, the present case emphasises the need for caution when treating patients with aripiprazole.

Abstract
Lamotrigine is an anticonvulsant that appears to have a mainly antidepressant effect and is indicated for the maintenance treatment of bipolar depression. Literature associated with obsessional symptoms related to lamotrigine treatment is limited. We report the emergence of obsessive symptoms during treatment with lamotrigine in a patient who subsequently experienced significant improvement after dose reduction and stopping of this medication. The obsessive symptoms associated with lamotrigine treatment were observed after the lamotrigine dose was increased to 100 mg/day. The possible mechanisms, including inhibition on the presynaptic release of glutamate and alteration of striatal dopamine uptake, are discussed. It is unclear why lamotrigine induces obsessions in some patients. Controlled studies are necessary to identify the population at risk for obsessionality in bipolar illness following treatment with lamotrigine and to investigate a possible dose-response relationship between obsessive symptoms and lamotrigine.

Abstract
A growing body of reports have indicated that free radicals are involved in the etiopathogenesis of some neuropsychiatric disorders. In the present study, we aimed to evaluate whether antioxidant enzymes (superoxide dismutase; SOD, glutathione peroxidase; GSH-Px, and catalase; CAT) activity levels and malondialdehyde (MDA), a product of lipid peroxidation, were associated with social phobia (SP). Eighteen patients diagnosed with SP and 18 healthy controls were enrolled. A clinical evaluation and measurements of MDA, SOD, GSH-Px and CAT were performed. Additionally, all patients were assessed with the Liebowitz Social Anxiety Scale (LSAC). The mean MDA, SOD, GSH-Px and CAT levels in the patient group were significantly higher than those in the control group. There was a positive correlation between LSAC scores and MDA, SOD, GSH-Px and LSAC levels, and between the duration of illness, and MDA, SOD and CAT levels in the patient group. In conclusion, our results suggest that there may be a relationship between increased antioxidant enzyme levels and MDA, and SP.

Abstract
Earlier studies have linked lipid metabolism to suicide and impulsive-aggressive behaviors. We previously reported that suicide attempters had significantly lower leptin and cholesterol levels than controls. Since lower cholesterol levels have been related to violence alone, we decided to evaluate serum total cholesterol and leptin levels in violent and non-violent suicide attempters. In the present study, 19 violent, 16 non-violent suicide attempters, and 20 age- and sex-matched healthy controls were compared for serum total cholesterol and leptin levels. Violent suicide attempters had significantly lower total cholesterol and leptin levels compared with those with non-violent suicide attempts. Our results suggest that low serum cholesterol and leptin levels are related to the following two dimensions of suicide attempts: suicidality and violence.

Abstract
It has been suggested that the extract of gingko biloba (EGb) may enhance the efficiency of the classic antipsychotic haloperidol in patients with chronic schizophrenia, especially on positive symptoms, and reduce serum superoxide dismutase (SOD) levels. Therefore, we decided to evaluate the therapeutic effect of EGb and to examine the effect of it on the levels of antioxidant enzymes in schizophrenic patients on olanzapine treatment. We hypothesized that EGb would have the beneficial effects on schizophrenic symptoms and might cause reductions in antioxidant enzymes. The subjects were randomly assigned to the two groups: olanzapine plus EGb (group I) (n=15) and olanzapine alone (group II) (n=14). The patients were evaluated at baseline and at week 8 with respect to the Positive and Negative Syndrome Scale (PANSS), serum SOD, catalase (CAT), and glutathion peroxidase (GPX) levels. At baseline, no statistically significant difference regarding the mean total PANSS scores between treatment groups was found. At the evaluation of week 8, a significant difference in mean Scale for the Assessment of Postive Symptoms (SAPS) scores but not in Scale for the Assessment of Negative Symptoms scores between groups was found. Total patients had statistically significant higher serum SOD, CAT and GPX levels compared to control groups at baseline. At 8 weeks, there were significant differences in the mean decrease in SOD and CAT levels but not in GPX levels between treatment groups. The changes in SOD and CAT levels were correlated with the change in SAPS in group I, but not in the group II. The present study supported the findings of the previous study demonstrating that EGb might enhance the efficiency of antipsychotic in patients with schizophrenia, particularly on positive symptoms of the disorder.

Abstract
Leptin is thought to be related to vegetative symptoms of depression such as alterations in food intake and weight. Fifty-seven drug-free patients and 26 healthy controls were enrolled in this study. We have found that the serum leptin levels were higher in patients with atypical depressive disorder than in controls, but not in patients with non-atypical depressive disorder, however, body mass index, age, and gender were not significantly different between these groups. Probably, these findings seem to be associated with some features of the atypical depressive disorders such as weight gain, a result of hyperphagia.

Abstract
Previous studies have shown that folate deficiency, increased homocysteine, impaired metylation have been identified in depressive disorder. Recently, growing research has resulted in the biological association between obsessive-compulsive disorder (OCD) and affective disorders. Therefore, in the present study it was evaluated whether or not folate and homocysteine levels changed. Serum folate and homocysteine concentrations were measured in 23 patients with OCD and in same number of controls. In addition, all patients were assessed by Yale-Brown Obsession Compulsion Scale (Y-BOCS). Serum folate values were significantly lower in OCD patients than in controls, while homocysteine concentrations were higher in patients compared with controls. Serum folate values were significantly and negatively related to Y-BOCS scores. Total serum homocysteine concentrations were positively correlated to Y-BOCS scores and the duration of illness. There was a trend toward a negative correlation between the concentrations of serum folate and homocysteine. In conclusion, we identified that a group of patients with OCD might have folate deficiency, higher homocysteine levels and probable impaired metylation and monoamine metabolism.

Abstract
Recently there has been increasing evidence that free oxygen species may play an important role in the pathophysiology of various neuropsychiatric disorders. The present study was performed to assess the changes in plasma nitric oxide (NO) levels in patients with obsessive-compulsive disorder (OCD) compared to age- and sex-matched normal controls. Twenty-three patients with OCD and 23 healthy volunteers were included in the study. NO values were determined in the plasma of normal healthy controls and the OCD patients. Plasma nitrate levels in OCD patients were significantly higher than those in controls and were significantly and positively correlated with Yale-Brown Obsession Compulsion Scale scores but not related to age or to the duration of illness. These findings indicated a possible role of increased NO may be relevant to the pathophysiology of OCD.

Abstract
The aim of the present study was to evaluate serum leptin levels to demonstrate whether or not its eventual alterations might have an etiopathogenetic significance in patients with obsessive-compulsive disorder (OCD). Thus, it was planned to examine whether serum leptin levels were affected by pure OCD (OCD-D), pure depression (D) or the comorbidity of OCD and depression (OCD+D). Forty-four patients with OCD (27 with OCD-D and 17 with OCD+D), 38 depressed patients and 30 control subjects were enrolled and serum leptin and cortisol levels were measured. According to the mean leptin levels, no significant difference was found between the OCD-D and control groups and between the OCD+D and D groups, while statistically significantly lower levels were found in the OCD+D and D groups than in control group. Significant difference in the mean leptin levels was found among groups even after controlling for body mass index or sex. The present study confirms the strong relationship between serum leptin and cortisol values and suggests that reduced leptin levels, rather than having an etiopathogenetic significance in patients with OCD, seem to be associated with patients with OCD and depression but not with pure OCD patients, and that OCD may be a heterogeneous subtype containing some biological indications of anxiety and affective disorders.

Abstract
A growing body of evidence indicates that oxidative stress is involved in the etiopathogenesis of some psychiatric disorders. In our previous study, we have found that social phobia (SP) seems to be associated with elevated antioxidant enzymes and malondialdehyde (MDA) levels, a lipid peroxidation product. In the present investigation, we sought to determine whether the increased radical burden observed in patients with SP would be attenuated with alleviation of symptoms. Thirty-nine patients diagnosed with generalized SP and 39 healthy controls participated in this study. The measurements of MDA, superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT) were performed before and after a period of 8 weeks of citalopram treatment. In this period, the patients received citalopram but controls did not. The initial dose of citalopram was 20mg, with 20 mg increments occurring every 2 weeks, to a maximum dose of 60 mg, with the mean daily dose of 38.9 +/- 13.3 mg/day. All patients were evaluated by using Liebowitz Social Anxiety Scale (LSAS). The mean MDA, SOD, GSH-Px and CAT levels of the patient group at baseline were significantly higher than those of controls. Antioxidant enzymes and MDA levels decrease significantly through citalopram treatment. Significant and positive correlation was observed between decrease in the total LSAS scores, and SOD or CAT levels. In conclusion, our results suggest that, in patients with SP, subchronic treatment with citalopram may decrease antioxidant enzymes and MDA values and that they are state markers of SP because they return to normal values with treatment.

Abstract
In this paper, we evaluated the new antipsychotic, quetiapine-induced sexual dysfunctions (SDs). The study group consisted of 36 patients with schizophrenia receiving quetiapine. The changes in general sexual functions were assessed by using Arizona Sexual Experience Scale (ASEX) and Udvalg for Kliniske Undersogelser (UKU) Side Effect Rating Scale at baseline and week 4. Also, prolactin (PRL) values were determined at baseline and week 4. There was statistically significant difference with respect to the mean ASEX score at week 4 compared with baseline. The most frequent SD was diminished libido in both male (31.8%) and female subjects (28.6%). No significant correlation was found between ASEX scores and PRL values. The results suggest that SDs are an important problem using even novel antipsychotic, quetiapine.

Abstract
It has been reported that nizatidine may reduce weight gain in schizophrenic patients on olanzapine treatment. Leptin has been reported to be associated with antipsychotic-induced weight gain. Thus, the purpose of the study was to evaluate whether nizatidine might be useful for the treatment of quetiapine-induced weight gain. Among the patients on the quetiapine monotherapy, 47 participated in the study for the two and half months of the open-label screening period. However, 28 patients who gained considerable weight in this period entered the 8-week, double-blind and placebo-controlled phase. These patients were randomly divided into two groups; quetiapine plus nizatidine (group I) and quetiapine plus placebo (group II) for the 8-week double-blind phase. The patients were evaluated at the baseline and at week 8 with respect to the positive and negative syndrome scale, body mass index, weight and serum leptin levels. The mean weight and leptin levels exhibited modest increases in both groups for the open-label screening period. In the double-blind period, in group I, a minimal, but not statistically significant, decrease in weight was observed, with a mean of 1.0 +/- 0.6 kg. The weight increased in group II. The leptin levels decreased by a mean of 0.6 +/- 0.6 ng/ml in group I, and increased by 1.0 +/- 0.9 ng/ml in group II. At evaluation at week 8, a trend toward statistical significance in the mean serum leptin levels between groups was detected. The results suggest that nizatidine treatment may stop but not reduce the weight gain and is correlated with leptin levels in patients with schizophrenia on quetiapine treatment.

Abstract
OBJECTIVE Previous studies demonstrate a relationship between lipid metabolism and suicide or impulsive-aggressive behaviours. Leptin seems to be related with lipid metabolism. Therefore, the aim was to measure total serum cholesterol and leptin levels in 16 medication-free schizophrenic patients with and without suicide attempts and in 16 healthy controls. METHOD Subjects were assessed by using Impulsivity Rating (IRS) and Modified Overt Aggression Scale (MOAS). RESULTS The patients had lower total cholesterol and leptin levels in serum compared with the controls. Significantly lower total cholesterol and leptin levels were observed in patients who had attempted suicide compared with those who had not. The levels were observed to be low in violent attempters when compared with non-violent attempters. MOAS and IRS scores were negatively correlated with both cholesterol or leptin levels in patients. CONCLUSION The results indicated that medication-free schizophrenic patients have statistically significant lower serum cholesterol and leptin levels compared with controls and the difference is obvious in suicide attempters compared with non-suicide attempters and in violent attempters than non-violent attempters.

Abstract
It has been reported that nizatidine may reduce the weight gain in schizophrenic patients receiving olanzapine treatment. Previous studies have demonstrated a relation between olanzapine-induced weight gain and serum leptin levels. Therefore, in the present study, it was planned to investigate the efficacy of nizatidine on the treatment of olanzapine-induced weight gain, and if available, whether leptin levels were associated with reductions in weight gain. Of the patients with schizophrenia on olanzapine treatment, 59 who gave informed consent entered a 3 month open-label screening period. Of them, 35 patients (59%) showed weight gain in excess of 2.5 kg. These patients were randomly divided into two groups; olanzapine plus nizatidine (group I) and olanzapine plus placebo (group II) for an 8-week double-blind phase. The patients were evaluated at the baseline and at week 8 with respect to the positive and negative syndrome scale, body mass index, weight and serum leptin levels. In the open-label period, olanzapine led to a considerable marked increase in weight and in serum leptin levels. There was no statistically significant difference between the groups with respect to weight at the beginning of the 8-week double-blind treatment period. Throughout the 8 week double-blind period, in group I, the weight decreased by 4.5 +/- 2.2 kg ( p<0.05). In contrast, weight increased in group II by a mean of 2.3 +/- 0.9 kg ( p>0.05). The leptin levels decreased by 4.4 +/- 2.3 ng/ml in group I ( p<0.01), and increased by 1.8 +/- 0.6 ng/ml in group II ( p>0.05). These changes were accompanied by changes in the leptin levels in both groups I and II. It is concluded that leptin seems to be strongly associated with olanzapine-induced weight gain and that nizatidine treatment may reduce the weight gain and the correlated leptin levels in patients with schizophrenia on olanzapine treatment.

Abstract
The aim of our study was to determine the frequency of dissociative disorders (DDs) among inpatients with conversion disorder (CD) in a university clinic settled in Eastern Turkey. During a period of 24 months, 59 consecutively admitted adult CD patients were screened with the Dissociative Experience Scale (DES). Patients who scored above 30 (DDs group) did not differ by age or gender from a group of inpatients who scored below 10 on the scale (comparison group). All patients in the two groups were then interviewed in a blind manner using the Dissociative Disorders Interview Schedule (DDIS) and Structured Interview for DSM-IV Dissociative Disorders (SCID-D). According to the SCID-D, 18 of 59 patients (30.5%) received a diagnosis of dissociative disorder; nine of these 18 patients (50%) were diagnosed as having dissociative identity disorder, eight (44.4%) were diagnosed as having dissociative disorder not otherwise specified (NOS), and one (5.6%) was diagnosed as having dissociative amnesia. Accordingly to the DDIS, borderline personality disorder was frequent in the DDs group, and all of the patients in the DDs group reported sexual abuse and neglect during childhood, latency, or adolescence. A high proportion of CD patients have significant dissociative pathology. The proper diagnosis of these patients has important implications for their clinical course.

Abstract
Sexual side effects are frequent and are recently being considered as effects of antidepressant treatment. One method to improve the sexual dysfunction associated with the use of antidepressants is to change to another antidepressant. In the present work, the consequences of switching to tianeptine in patients with antidepressant-induced sexual dysfunction were studied. The study group comprised 23 patients with major depressive disorder who experienced antidepressant-induced sexual dysfunction. These antidepressants were stopped and switched to tianeptine (12.5mg x 3/day). All patients were screened by using the clinical global impression-improvement scale (CGI-I), the Hamilton depression rating scale (HAM-D) and the Arizona sexual experience scale (ASEX) at the beginning of the study, and at weeks 4 and 8. No patient failed to tolerate 37.5mg of tianeptine or to complete the study except for one patient becoming pregnant. Paired t-tests revealed a significant difference between baseline and week 4 or week 8 in scores on both the HAM-D and ASEX. At 8 weeks, six patients were rated as very much improved (CGI-I=1) and ten patients were rated as much improved (CGI-I=2). Thus, with a CGI-I score of 2 or less used to indicate a positive response, 72.7% of the patients were responders. The results suggest that switching to tianeptine appears to be useful for alleviating sexual dysfunction caused by other antidepressants.

Abstract
There is evidence of an etiopathogenetic role of free radicals (FRs) in some neuropsychiatric disorders. The aim of the present study was to determine whether the activity levels of some antioxidant enzymes [glutathione peroxidase (GSH-Px), superoxide dismutase (SOD) and catalase (CAT)] and malondialdehyde (MDA), a product of lipid peroxidation, were associated with panic disorder (PD). Twenty patients diagnosed with PD and 20 healthy controls were enrolled in this study. A clinical evaluation and measurements of GSH-Px SOD, CAT and MDA were performed. Additionally, all patients were assessed by the Panic Agoraphobia Scale (PAS). The mean GSH-Px, SOD and MDA levels of the patient group were significantly higher than those of the controls. There was a significant positive correlation between PAS scores and GSH-Px, SOD and MDA levels and between the duration of illness and SOD, CAT and MDA levels in the patient group. In conclusion, our results suggest that FRs may be involved in PD.

Abstract
Low cholesterol levels have been reported in patients with manic episodes. Leptin seems to be strongly associated with lipid metabolism. In the present study, therefore, serum total cholesterol and leptin levels were compared in 16 patients with manic episodes, 16 with bipolar I disorder in full remission and 16 healthy controls. The serum total cholesterol and leptin levels were measured and Young Mania Rating (YMRS) and Hamilton Depression Rating Scales (HAM-D) were administered for each subject. Both the patients with manic episodes and the patients with bipolar I disorder in full remission had markedly low serum cholesterol and leptin levels compared with controls, though the difference was more obvious in patients with manic episodes. In addition, there were negative correlations between YMRS scores and serum cholesterol or leptin levels in the patients with manic episodes. Our results suggest that the patients with manic episodes and those with bipolar I disorder in full remission seem to be associated with decreased serum cholesterol and leptin levels.

Abstract
BACKGROUND Weight gain is a common adverse effect associated with the use of most antipsychotic drugs. Leptin has been reported to be associated with antipsychotic-induced weight gain. Previous studies have demonstrated a relationship between the atypical antipsychotics clozapine and olanzapine and serum leptin levels. We planned to comparatively investigate the effects of the atypical antipsychotics quetiapine, olanzapine, risperidone, and clozapine on leptin and triglyceride levels and weight gain. METHOD The study population comprised 56 patients with DSM-IV schizophrenia, who were divided into 4 treatment groups: quetiapine (N = 14), olanzapine (N = 14), risperidone (N = 14), or clozapine (N = 14) monotherapy, and a control group of 11 patients receiving no psychopharmacologic treatment. The patients were evaluated at baseline and at the sixth week according to the Positive and Negative Syndrome Scale (PANSS), body mass index (BMI), weight, and fasting serum leptin and triglyceride levels. Data were gathered in 2001 and 2002. RESULTS Olanzapine and clozapine caused a marked increase in weight and serum triglyceride and leptin levels, though increases in these variables were modest in the patients receiving quetiapine and minimal in those receiving risperidone. There were positive correlations between serum leptin levels and BMI and triglyceride levels. Clinical efficacy, as indicated by decrease in total PANSS scores, was associated with leptin levels in all atypical antipsychotic groups. CONCLUSION Our results suggest that leptin may be associated with olanzapine- and clozapine-induced weight gain and that quetiapine appears to have modest influence and risperidone appears to have minimal influence on leptin and triglyceride levels and weight gain compared with olanzapine and clozapine.

Abstract
There is mounting evidence indicating that reactive free radical species (FRs) are involved in initiation and development of many different forms of human pathologies including psychiatric disorders. In the present study, we aimed to determine whether antioxidant enzyme (glutathione peroxidase, GSH-Px; superoxide dismutase, SOD and catalase, CAT) activities and malondialdehyde (MDA) levels, a product of lipid peroxidation, were associated with post-traumatic stress disorder (PTSD). The study comprised 14 patients who had been diagnosed with PTSD according to DSM-IV criteria and met the admission criteria and 14 healthy controls. The activities of GSH-Px SOD, CAT and MDA were measured in both the patients and controls. In addition, all patients were assessed using the Clinician Administered PTSD Scale (CAPS). The mean GSH-Px, SOD, CAT activities and MDA levels of the patient group did not differ from those of the controls. However, in patients, the GSH-Px and SOD activities were significantly and positively correlated with CAPS scores, while there was a trend toward positive correlations between CAPS scores and MDA or CAT. In conclusion, our results suggest that the production of FRs does not seem to be related to PTSD.

Abstract
The pathophysiology of akathisia still remains controversial. Iron deficiency was proposed to be an important factor in the development of akathisia. In the present study, it was aimed to compare levels of serum iron and linked variables in chronic akathisic (n=30), and non-akathisic patients (n=30) with schizophrenia and healthy controls (n=30) because of the controversy in the association of iron and akathisia. The Barnes Akathisia Scale for akathisia and Simpson-Angus Rating Scale for extrapyramidal side effects were used. Serum iron and linked variables and hematological profile of the patients and control subjects were determined. Serum iron levels were significantly lower both in akathisic and non-akathisic groups compared to the control group (P<0.001). Moreover, akathisic patients had significantly lower iron levels than non-akathisic patients (P<0.05). Total iron binding capacity was significantly higher in patients with akathisia compared to the control group (P<0.01). Although non-akathisic patients had a mild increase in total iron binding capacity, it was not statistically significant compared to the control group (P>0.05). Ferritin levels were determined to be significantly lower in both groups compared to the control group (P<0.01). In addition, there was a significant difference in ferritin levels between the patients with and without akathisia (P<0.05). In conclusion, our results support the hypothesis that an association between akathisia and iron metabolism exists.

Abstract
OBJECTIVE To evaluate serum leptin levels (an adipocyte hormone involved in the suppression of appetite) in patients with premature ejaculation before and after treatment with citalopram, a selective serotonin reuptake inhibitor, with the hypothesis that leptin levels might become normal during this treatment. PATIENTS AND METHODS The inhibitory effect of serotonin on libido, ejaculation and orgasm is well documented. Although there is no direct evidence of an association involving brain pathways which are related to sexual behaviour, there is an interaction between leptinergic and serotonergic systems. In a previous study serum leptin levels were high in patients with premature ejaculation. The present study comprised 30 patients with premature ejaculation according to the Diagnostic and Statistical Manual of Mental Disorders Third Revised Version. Fifteen patients (group I) were randomly assigned to 8 weeks of citalopram treatment and the remainder (15, group II) received no therapy. The patients were asked to determine the average intravaginal ejaculation latency time, and their fasting serum leptin levels were measured at baseline and after 8 weeks. RESULTS There was no significant difference in the mean intravaginal ejaculation latency time between the groups at baseline; it increased after 8 weeks of treatment with citalopram in group I, to a mean (sd) of 209 (72.1) s, but not in group II. No difference was detected in leptin levels between the groups at baseline, but at 8 weeks they were lower in group I. CONCLUSION As hypothesized, leptin levels decreased in patients with premature ejaculation after treatment with citalopram, and this decrease seemed to be linked to the therapeutic effect. Further experimental studies are needed.

Abstract
BACKGROUND Conversion disorder (CD) is a common disease and its importance still continues in Turkey and particularly in Eastern Turkey. The aim of this study is to examine sociodemographic and clinical characteristics of CD. METHOD Among 198 consecutive patients having CD diagnosed by structured DSM-III-R clinical interview, the psychosocial characteristics of the patients were clinically investigated. RESULTS The most common subtype of CD was non-epileptic seizure (NES) (41.4 %). The psychosocial stress factors were found in the initiation or at the last episode of the disorder (88.9 %). The most prominent problem related with primary support group was traumatic event (37.9 %) followed by problems associated with migration and related economical problems which are the most important problems of the study area. The incidence of depressive disorders was high in patients with CD, and the histrionic personality disorder was the most prominent personality pathology among the patients. Direct referral to psychiatry clinics appeared to be low (12.1 %). CONCLUSION Our findings have shown that traumatic events may have an important role in the occurrence, severity and duration of CD, and most of the patients seek help from religious healers. The study has also revealed that lower education level and socioeconomic and sociocultural problems may play a role in the occurrence of the disorder as well as regarding its course.

Abstract
Post-traumatic stress disorder (PTSD) has been associated with decreased neopterin levels. In the present study, we evaluated whether this low neopterin levels would normalize following pharmacotherapy with sertraline in PTSD. Fourteen patients with PTSD and 14 controls were enrolled in the study. A clinical evaluation and measurements of neopterin levels before and after sertraline treatment were performed. In addition, all patients were assessed with the Clinician Administered PTSD Scale (CAPS). The mean neopterin levels were significantly lower in the patient group than control group at baseline and were negatively correlated with the duration of illness, or severity of illness. Sertraline treatment decreased the symptoms of PTSD; however this was not accompanied by a significant increase in neopterin production. In conclusion, our results reveal that the failure for neopterin to normalize through symptom alleviation suggests that either neopterin may be a trait marker of the illness, or that more sustained treatment is necessary to elevate the neopterin production.

Abstract
The efficacy of irreversible and reversible monoamine oxidase inhibitors (MAOIs) in the treatment of social phobia (SP) is well established. Recently, selective serotonin reuptake inhibitors (SSRIs) have been used more frequently. In the present study, the efficacy and side-effect profile of citalopram, an SSRI, and moclobemide, the only MAOI used in Turkey, were compared. The 71 patients diagnosed with SP according to DSM-III-R were randomly assigned to two subgroups; citalopram (n = 36) or moclobemide (n = 35). The study was an 8-week, randomized, open-label, rater-blinded, parallel-group trial. All patients were assessed by Hamilton anxiety rating (HAM-A), Liebowitz social anxiety (LSAS), clinical global impression-severity of illness (CGI-SI) and clinical global impression-improvement (CGI-I) scales. There was a similar percentage of responders (citalopram 75%, n = 27 and moclobemide 74.3%, n = 26), with a >50% or greater reduction in LSAS total score and ratings of "very much" or "much improved" on the CGI-I. None of the patients withdrew from the study. The results of the present study suggest that citalopram has shown promising results in patients with SP.

Abstract
BACKGROUND Despite the limited number of available study comparing of their efficacy, selective serotonin re-uptake inhibitors (SSRI) have been thought to have beneficial effects for the patients with premature ejaculation. In the present study, we decided to examine the efficacy of citalopram, an SSRI, in the treatment of premature ejaculation. METHOD The study was consisted of 26 married patients diagnosed with premature ejaculation according to Diagnostic and Statistical Manual of Mental Disorders Third Revised Version (DSM-III-R). The patients were randomly assigned to two groups, citalopram (group I) and placebo (group II), each consisting of 13 patients. The effects of drug on the ejaculatory function were assessed by the intravaginal ejaculation latency time. Additionally, all patients were screened by using Clinical Global Impression-Improvement Scale (CGI-I) and Yonsei Sexual Function Inventory-II (YSFI-II). RESULTS The increase in the intravaginal ejaculation latency time in the citalopram group was statistically significant than that of placebo group. In addition, with respect to the subscales of the YSFI-II scale, similar overall significant improvements were seen in the patients given citalopram compared to those given placebo. Of group I patients, five (38.5%) were considered as 'very much improved' and four (30.8%) 'much improved' by CGI-I and only one of group II patients (7.7%) showed 'much improved'. CONCLUSION The patients treated with citalopram showed significantly greater improvement compared to the patients receiving placebo.

Abstract
In the present study, we aimed to examine the efficacy of sildenafil in patients with an antipsychotic (olanzapine)-induced erectile dysfunction (ED). The study group comprised 10 patients who experienced ED associated with the use of olanzapine. The patients initially received 50 mg sildenafil at baseline. If clinically indicated, titration up to 100 mg was permitted. All patients were assessed by Clinical Global Impression-Improvement (CGI-I) and International Index of Erectile Dysfunction (IIEF) scales at baseline and weeks 2 and 4. At final assessment, three patients were considered 'very much improved' and four 'much improved' according to CGI-I. Our results suggest that sildenafil use is effective and well-tolerated in patients with olanzapine-induced ED.

Abstract
Weight gain is a frequent adverse effect associated with lithium use. Leptin is an adipocyte hormone, regulating food intake and energy balance providing the hypothalamus with information on the amount of body fat. Therefore, we planned to evaluate whether lithium administration was associated with weight gain, and leptin levels. The study consisted of 15 consecutive inpatients with bipolar I disorder according to DSM-III-R. The fasting serum leptin levels were measured. The patients were evaluated at baseline and at the eighth week according to the body mass index, weight, Young Mania Rating (YMRS) and Hamilton Depression Rating (HAM-D) scales, and serum leptin levels. With respect to the leptin levels, a significant difference was observed after lithium treatment. There was a significant positive correlation between the changes in leptin levels and the duration of illness. The change in total YMRS scores correlated with change in leptin levels and that in weight. In conclusion, our result suggest that leptin may be associated with lithium-induced weight gain.

Abstract
BACKGROUND Typical antipsychotic drugs frequently cause hyperprolactinemia and even galactorrhea. In addition, these side effects may result in noncompliance with antipsychotic treatment. Capacity to avoid hyperprolactinemia has been accepted as one atypical criterion. The aim of the present study was to compare effects of haloperidol, the most commonly used antipsychotic, and quetiapine, a novel antipsychotic agent used in Turkey, on serum prolactin (PRL) levels. METHODS The study consisted of 35 females diagnosed with schizophrenia according to the Diagnostic and Statistical Manual of Mental Disorders, 4(th) ed. (DSM-IV). Thirty-five patients in a drug-free period for at least 2 weeks were included to randomized quetiapine (n = 18) and haloperidol (n = 17) treatment group. All patients were assessed by Brief psychiatric rating scale (BPRS), Positive and negative syndrome scale (PANSS), and Extrapyramidal symptoms rating scale (ESRS). PRL levels were measured both at the beginning and at the sixth week of the study. RESULTS Both treatment groups exhibited significant improvements in clinical signs as evaluated by BPRS and PANSS. While there was no significant difference in PRL level between groups at the beginning of the study, control prolactin (PRL) levels were significantly lower in quetiapine compared to haloperidol group. While no quetiapine group patients exhibited galactorrhea, we observed that two patients from the haloperidol group had galactorrhea related to hyperprolactinemia. CONCLUSIONS The present study revealed that quetiapine is not associated with increase in PRL secretion in contrast to the conventional antipsychotic haloperidol.

Abstract
To examine the importance of free radicals in the pathogenesis of obsessive-compulsive disorder (OCD), we aimed to evaluate whether malondialdehyde (MDA), a product of lipid peroxidation, and antioxidant enzyme [superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and catalase (CAT)] activity levels were associated with OCD. The patients were divided into two subgroups according to whether DSM-IV major depressive disorder (MDD) was accompanied (OCD + MDD) or not (OCD - MDD). The MDA and antioxidant enzyme levels both in patients and controls were determined. SOD activity levels were significantly higher in the OCD + MDD group compared with the control and the OCD - MDD group. Although the OCD - MDD group had slightly higher SOD activity levels as compared with the controls, the difference was not statistically significant. GSH-Px activity levels were statistically significantly higher in both groups compared with controls. Likewise, there was a significant difference in GSH-Px activity levels between the OCD + MDD and OCD - MDD group. CAT activity levels were slightly higher in the OCD + MDD group compared with the OCD - MDD and control group. MDA levels in both groups were significantly higher than in controls. In addition, the difference in MDA levels between both groups was statistically significant. In conclusion, our results suggest that OCD is associated with free radicals and that it may be a heterogeneous subtype including some biological indications of anxiety and affective disorders. More comprehensive and detailed studies are needed to decipher the exact role of free radicals in OCD.

Abstract
Leptin is a fat cell-derived hormone signaling the hypothalamus about food intake, the regulation of weight, and sexual behavior. The inhibitory effect of serotonin on libido, ejaculation, and orgasm is well documented. There is an interaction between leptinergic and serotonergic systems in the central nervous system. This study was conducted to evaluate serum leptin levels of the patients with premature ejaculation. The study group consisted of 15 patients with premature ejaculation according to Diagnostic and Statistical Manual of Mental Disorders, Third Revised Version (DSM-III-R) and 15 healthy controls. The fasting serum leptin levels were measured. Significantly high serum leptin levels in the patients were found after body mass index or age adjustment. The intravaginal ejaculation latency time negatively correlated with leptin levels in both patient and control groups. In addition, there was a positive correlation between leptin levels and the duration of illness. It would appear that leptin may be associated with premature ejaculation.

Abstract
Neopterin has recently gained growing importance as an immunological marker in psychiatric disorders. In the present study, we aimed to evaluate whether the dexamethasone suppression test (DST) and neopterin were associated with posttraumatic stress disorder (PTSD). Fourteen patients with PTSD and 14 controls were enrolled in the study. A clinical evaluation and measurements of cortisol and neopterin levels before and after DST were performed. Additionally, all patients were assessed by Clinician Administered PTSD Scale (CAPS). There was a significantly higher DST nonsuppression in the patient group than control group. There were positive correlations between the duration of illness and CAPS, basal cortisol or postdexamethasone cortisol levels in the patient group. The mean neopterin levels for both before and after DST were significantly lower in the patient group than control group. In conclusion, our results suggest that not only the patients with PTSD have considerable DST nonsuppression but also PTSD may be associated with neopterin.

Abstract
The growing number of studies examining the relationship between suicide and lipid metabolism are based upon studies suggesting that cholesterol-lowering procedures may increase the risk of death due to suicide or impulsive-aggressive behavior. Leptin seems to be strongly associated with lipid metabolism. In the present study, serum total cholesterol and leptin levels were compared in 24 suicide attempters and 24 healthy controls. The patients with suicide attempts had significantly lower serum cholesterol and leptin levels than controls. There was a positive correlation between cholesterol and leptin levels in both groups. Our results suggest that suicide attempts seem to be associated with decreased serum cholesterol and leptin levels.
