Risk of Relapse Assessment Scale for Metamphetamine Abusers: Reliability and Validity Study of the Turkish Version.

Background: This study aims to investigate the validity and reliability of the Turkish adaptation of the 16-item Risk of Relapse Assessment Scale (RRAS) for methamphetamine abusers. Methods: A total of 160 patients diagnosed with methamphetamine use disorder were included in this study to evaluate the validity and reliability of the scale. The comparison of the relationship between the Risk of Relapse Assessment Scale, the Substance Craving Scale, and the Relapse Prediction Scale was also carried out. The validity of the Risk of Relapse Assessment Scale was examined in the first step by exploratory factor analysis. The suitability of the data for exploratory factor analysis was evaluated by Kaiser-Meyer-Olkin test and Barlett's test. Cronbach's α coefficient and corrected item-total correlation value were used to test the reliability of the scale. The validity results of Risk of Relapse Assessment Scale were tested by confirmatory factor analysis. The significance level was set at P < .05 for all analyses. Results: Considering the examination of the internal consistency values of the Risk of Relapse Assessment Scale, Cronbach's α value was detected to be 0.90, and Cronbach's α value of the subscales ranged from 0.72 to 0.90. The study determined that the goodness of fit values for RRAS were χ 2/df =2.13, P < .001, goodness of fit index = 0.88, comparative fit index = 0.92, normed fit index = 0.86, Trucker-Lewis index = 0.90, root mean square error of approximation = 0.08, and standardized root mean squared residual = 0.06. Conclusion: Our findings demonstrate that Risk of Relapse Assessment Scale is a valid and reliable measurement tool for assessing the risk of methamphetamine relapse in Turkish.

Refractory obsessive-compulsive disorder with symptoms regressing after thalamic infarction: A case report.

Obsessive compulsive disorder (OCD) is a common neuropsychiatric disorder involving predominantly the cortico-striato-thalamo-cortical loop. Although it is usually associated with various disorders of basal ganglia and thalamus, it is difficult to say what kind of impairment causes this situation exactly. Structural brain lesions may be one of the rare causes of refractory psychiatric symptoms. Analysis of such type of cases gives an idea about the neurobiology of psychiatric diseases. In this manuscript, we presented a case of refractory OCD with symptoms regressing after thalamic infarction and discussed with relevant literature.

Stress in couples undergoing assisted reproductive technology.

PURPOSE: To determine the associations between pre-treatment self-reported stress level, salivary cortisol levels, and clinical pregnancy outcome in couples undergoing assisted reproductive technology treatment (ART). STUDY DESIGN: Seventy-five couples (150 patients) undergoing ART treatment were enrolled in this study. Psychological variables were assessed using the Perceived Stress Scale, Beck Anxiety Inventory, State-Trait Anxiety Inventory, and Beck Depression Inventory. Salivary cortisol levels were obtained from each couple prior to commencing gonadotropin treatment at several times (upon waking and at 15, 30, and 60 min after waking). RESULTS: There was no statistically significant association between the self-reported stress levels and the ART treatment outcome in couples. Women with a successful outcome after ART treatment had higher median salivary cortisol levels than women who had an unsuccessful result [24.7 (19.9-63.1) vs. 20.7 (10.4-30.4), respectively]. There was no statistically significant difference in the median salivary cortisol levels of men in relation to ART treatment outcome. Salivary cortisol levels of the couples were not correlated. CONCLUSIONS: Women who had higher median salivary cortisol levels in the pre-treatment period had a higher clinical pregnancy rate. This result suggests that moderately increased activity of the hypothalamic-pituitary-adrenal axis during ART treatment might be associated with successful conception.

Evaluation of Transcranial Magnetic Stimulation Efficiency in Major Depressive Disorder Patients: A Magnetic Resonance Spectroscopy Study.

OBJECTIVE: Repetitive transcranial magnetic stimulation (rTMS) is an effective treatment for major depressive disorder (MDD). This study evaluated the antidepressant effect of rTMS and examined how it affected N-asetyl aspartate (NAA), choline (Cho), creatine (Cr), lactate (Lac), myoinositol (mIns), glutamate (Glu), glutathione (GSH), and glutamine (Gln) metabolite levels in the left dorsolateral prefrontal cortex (DLPFC) of MDD patients who were not receiving antidepressant medication. METHODS: In total, 18 patients (10 female, 8 male) were evaluated. Each patient underwent H magnetic resonance spectroscopy (H-MRS) before and within 3 days of completion of TMS therapy. All patients completed 20 sessions of rTMS directed at the left DLPFC over a 2-week period. The Hamilton Depression Scale (HAMD) scores of patients were calculated, and their responses to treatment were assessed within 1-3 days of completion of TMS. RESULTS: We found statistically significant differences in HAMD scores before and after rTMS. Moreover, the peak metabolite ratios of NAA/Cr, GSH/Cr, and Gln/Cr were significantly higher after rTMS compared to those before rTMS. CONCLUSION: Increased understanding of the mechanism of action of TMS will improve its application and may stimulate development of new-generation therapeutic agents.

Toxoplasma gondii - obsessive -compulsive disorder relationship: is it different in children?

BACKGROUND AND AIM: Obsessive-compulsive disorder (OCD) is a common neuropsychiatric illness. Although the etiology of OCD is still unknown, recent investigations have associated development of OCD with infectious illness. Toxoplasma gondii (T. gondii) is a neurotropic protozoan parasite that causes infection of the central nervous system. In the last decade, a lot of researches have focused on the possible relationship between exposure to T. gondii and neuropsychiatric disorders such as schizophrenia. Therefore, in this study, it was aimed to investigate a possible association between Toxoplasma infection and OCD in children and adolescents. METHODS: We selected 55 patients with OCD (aged between 7 and 16 years) and 59 healthy children and adolescents (aged between 7 and 16 years), and investigated the seropositivity rate for anti-Toxoplasma IgG antibodies by enzyme-linked immunosorbent assay. RESULTS: The seropositivity rate for anti-T. gondii IgG antibodies among OCD patients (21.82%) was found to be higher than the rate in control group (15.25%). However, the difference between the OCD group and the control group was not statistically significant (p > .05). CONCLUSION: In contrast to studies in adult patients, the results of this study do not support the relationship between T. gondii and OCD children and adolescents.

Does Psychodrama Affect Perceived Stress, Anxiety-Depression Scores and Saliva Cortisol in Patients with Depression?

OBJECTIVE: Little is known about the effects of psychodrama group therapy on the level of stress, anxiety and depression of the group members, and the biological markers of stress. The aim of this study test cortisol level as a biological reflection of some mental characteristics gained by the psychodrama method in coping with stress. METHODS: Depressive patients aged between 18 and 65 years, who diagnosed with depression according to DSM-5, without psychiatric comorbidity, who do not use drugs and were available for psychodrama were enrolled into the study. These patients were evaluated using the Perceived Stress Scale, State-Trait Anxiety Inventory and Beck Depression Inventory. In order to observe the circadian rhythm of cortisol, samples were collected from the participants before lunch, before dinner and before going to sleep on the day before psychodrama and on the 0, 15th, and 30th minutes after awakening in the morning of the psychodrama day; as well as just before and after the psychodrama session. Saliva cortisol level just before the initial session of psychodrama group therapy was compared with the saliva cortisol level just after the last psychodrama session at the end of 16 weeks. RESULTS: Statistically significant difference was determined between the scores of perceived stress scale, STAI-1, STAI-2, beck depression inventory and salivary cortisol level before and after psychodrama session. There was significant decrease in both the scale scores and salivary cortisol after vs. before psychodrama. CONCLUSION: This results is important as it shows the biological aspect of clinical improvement. Further studies would provide us with better understanding of the effects of psychodrama group psychotherapy on depressive mood and biological projections by means of short-term and long-term follow-up studies.

Effects of Relaxation Exercises and Music Therapy on the Psychological Symptoms and Depression Levels of Patients with Schizophrenia.

PURPOSE: This study aims to identify the effects of relaxation exercises and music therapy on the psychological symptoms and depression levels of patients with chronic schizophrenia. MATERIALS AND METHODS: This semi-experimental study was conducted using pre- and post-tests with a control group. The study population consists of patients with schizophrenia who regularly attended community mental health centers in the Malatya and Elazig provinces of Turkey between May 2015 and September 2015. The study's sample consists of 70 patients with schizophrenia (n=35 in the control group; n=35 in the experimental group) who were selected randomly based on power analysis. The "Patient Information Form," the "Brief Psychiatric Rating Scale (BPRS)" and the "Calgary Depression Scale for Schizophrenia (CDSS)" were used for data collection. Patients in the experimental group participated in relaxation exercises and music therapy 5 times a week for 4 weeks. The experimental group of 35 persons was divided into three groups of approximately 10-12 individuals in order to enable all participants to attend the program. No intervention was applied to the patients in the control group. The data were evaluated using percentage distribution, arithmetic means, standard deviations, Chi-square and independent samples t-tests. RESULTS: The study found that patients in the experimental group showed a decrease in total mean scores on the BPRS and CDSS; the difference between the post-test scores of the experimental group and the post-test scores of the control group was statistically significant (p<0.05). The practice of relaxation exercises and music therapy was proven to be effective in reducing schizophrenic patients' psychological symptoms and levels of depression. CONCLUSION: Relaxation exercises and music therapy can be used as a complementary therapy in the medical treatment of patients with chronic schizophrenia.

Association between latent toxoplasmosis and clinical course of schizophrenia - continuous course of the disease is characteristic for Toxoplasma gondii-infected patients.

The aim of the present study was to investigate the association between various clinical aspects of schizophrenia and seropositivity against Toxoplasma gondii (Nicolle et Manceaux, 1908). We selected 94 patients with schizophrenia and investigated the seropositivity rate for anti-T. gondii IgG antibodies by ELISA. Clinical parameters of schizophrenic patients such as illness type and status, clinical course, awareness of the illness and need for electroconvulsive therapy (ECT) were compared with their serological status. Anti-T. gondii IgG antibodies were detected in 43 (46%) of schizophrenic patients. Chronic patients had a rate of 34 (72%) seropositivity, whereas 9 (22%) of the patients with partial remission showed evidence of latent toxoplasmosis. Of continuous patients, 35 (81%) were found to be seropositive and this rate was significantly more than in the other groups. The rate of latent toxoplasmosis was detected significantly higher in patients who lack awareness of schizophrenia (36, i.e. 72%) than the patients who were aware of their illnesses (7, i.e. 16%). Anti-T. gondii IgG antibodies were detected in 38 (70%) of ECT performed patients while this percentage was 13% in the ones who had never been treated with ECT. This difference was also statistically significant. We showed that Toxoplasma-infected subjects had 15× higher probability of having continuous course of disease than Toxoplasma-free subjects. Our results put forth the possibility of latent toxoplasmosis to have a negative impact on the course of schizophrenia and treatment response of schizophrenic patients.

The neuropsychological and neurophysiological profile of women with pseudoseizure.

OBJECTIVE: Our aim in this study was to compare the assessments of neuropsychological tests and the p50 neurophysiological test of patients with seizure diagnosed as conversion disorder and healthy control subjects, and to investigate the neurological status in conversion disorder with pseudoseizure. METHODS: A total of 22 female conversion disorder patients with convulsions diagnosed according to SCID-I/CV and 22 healthy women were included in the assessment. The participants were administered WMS-R, the cancellation test, and the Stroop test as neuropsychological tests and p50 was assessed as a neurophysiological test. RESULTS: The patient's results for the neuropsychological tests were found to be significantly low compared to the control group. The p50 sensory gating ratios of the patient group were statistically significantly lower than the controls. There was no significant correlation between the neuropsychological test scores and gating ratios of the patient and control groups. CONCLUSIONS: This study is the first to check sensory gating in conversion disorder patients with pseudoseizure and its most important result is finding reduced p50 sensory gating in patients. Our results suggest that these patients have a neurological tendency to this disease due to functional neurophysiological features.

Acute and chronic effects of electroconvulsive treatment on oxidative parameters in schizophrenia patients.

Electroconvulsive therapy (ECT) is an effective treatment alternative for schizophrenia. Previous studies have already indicated the possible effects of oxidative stress in this disorder. However, there have been no previous studies evaluating the effects of ECT on the oxidative stress in these patients. We therefore aimed to investigate the acute and chronic effects of ECT on serum levels of oxidant and antioxidant molecules in schizophrenia patients (n=28). The serum MDA and CAT levels of the patients with schizophrenia were higher than that of the controls before ECT (n=20) but there was no significant difference in the serum NO and GSH levels of the patient groups compared to the controls. We found that the NO levels of the patients were higher than the controls in the group experiencing their first episode but not in the chronic group. There was a significant clinical improvement in the patients in terms of BPRS, SANS and SAPS reduction after the 9th ECT, but not the 1st ECT. Serum MDA levels were significantly reduced compared to the baseline after the 9th ECT session although there was no significant difference after the 1st session. Separate evaluation of the patient groups revealed that the significant MDA decrease following ECT was in the patients experiencing their first episode and not in the chronic group. No significant difference was noted in the serum levels of other oxidant and antioxidant molecules after either the 1st or 9th ECT session. These results suggest that ECT does not produce any negative effect on oxidative stress in patients with schizophrenia.

Pituitary volume in patients with panic disorder.

Panic patients have many functional deficiencies in the hypothalamic-pituitary-adrenal (HPA) axis. Previous studies have shown changed pituitary gland volume in some psychiatric disorders that have functional deficiencies in the HPA axis. However, to date no study has evaluated the pituitary gland volume in patients with panic disorder (PD). We investigated the pituitary gland volume in patients with PD (n=27) and age- and sex-matched healthy controls (n=27), using 1.5-T magnetic resonance imaging in this study. Analysis showed that patients with PD had significantly smaller pituitary volume compared to healthy subjects. Patients with agoraphobia especially had a significantly smaller pituitary volume than patients without agoraphobia. There was a significant relationship between the pituitary volume and both the severity of symptoms and the illness duration in the patient group. The results show that patients with PD have reduced pituitary volume, which may reflect the functional abnormalities seen in this disorder. These findings may help us better understand the pathology of PD.

Is there any role of Toxoplasma gondii in the etiology of obsessive-compulsive disorder?

Obsessive-compulsive disorder (OCD) is a common psychiatric illness. Although the aetiology of OCD is still unknown, the family-genetic data show that familial forms of OCD may be associated with a specific genetic susceptibility. Recent investigations have associated development of OCD with infectious illness. Toxoplasmic encephalitis (TE) is a common presentation of Toxoplasma gondii infection of the central nervous system (CNS). The most commonly affected CNS region in TE is the cerebral hemisphere, followed by the basal ganglia, cerebellum and brain stem. The basal ganglia has been implicated in the development of OCD. Therefore, in this study, it was aimed to investigate a possible association between Toxoplasma infection and OCD. We selected 42 patients with OCD and 100 healthy volunteers, and investigated the sero-positivity rate for anti-Toxoplasma IgG antibodies by Enzyme Linked Immunosorbent Assay (ELISA). The sero-positivity rate for anti-T. gondii IgG antibodies among OCD patients (47.62%) was found to be significantly higher than the rate in healthy volunteers (19%). This is the first report to examine a potential association between Toxoplasma infection and OCD. The main finding of the present study is an increased level of IgG antibodies to T. gondii in OCD patients when compared with the level in healthy controls. There might be a causal relationship between chronic toxoplasmosis and the aetiology of OCD.

[Patients' explanation models for their illness and help-seeking behavior]. / Psikotik Hastalarda Hastalik Açiklama Modeli ve Care Arama Davranisi

OBJECTIVE: The aim of this study was to investigate some variables that affect patients' explanation models for their illness and help-seeking behavior. METHODS: Sampling was done between 2002 and 2003 among psychiatric patients who were admitted to university hospital in Malatya. Diagnoses of schizophrenia and schizoaffective disorder were made according to DSM-IV criteria. A semi-structured interview based on a short questionnaire was conducted for collecting patient demographic data, and patient explanatory model for illness and help-seeking behavior. RESULTS: The 88 patients that were evaluated included 50 males and 38 females. The mean age of the patients was 31.22+/-9.29 years (range: 16-57 years). In explaining their disease, 46.6% of the patients cited family trouble, 42% their inner problems, 19.3% economic difficulties, and 10.2% cited the consequences of supernatural forces. Among the patients, help-seeking behavior included visiting traditional and religious healers (51.1%), presenting to medical doctors (19.3%), and visiting a psychiatrist (65.9%). CONCLUSION: The study revealed that patients with low-level education were more prone to seek religious solutions and those with high-level education tended to visit a psychiatrist. It has been suggested that psycho-educational programs for patients and families will be very useful in ameliorating the problems created by the disease.

The role of oxidative stress in postoperative delirium.

AIM: This study aimed to determine a marker that predicts delirium using preoperative oxidative processes in patients undergoing cardiopulmonary bypass surgery. METHOD: Twelve of the 50 patients included in the study showed signs of delirium during postoperative follow-up. The Delirium Rating Scale was used in patients with delirium according to DSM-IV-TR in the postoperative period. Venous blood samples were obtained from the patients the day before and the day after the surgery to determine plasma antioxidant enzyme levels. RESULTS: While there were no differences in preoperative superoxide dismutase (SOD), glutathione peroxidase (GSH-Px) and malondialdehyde (MDA) levels in both groups, catalase (CAT) levels were significantly lower in the delirium group. Postoperative SOD and MDA levels were also higher in the delirium group, while the GSH-Px levels were found to be lower when compared with those during the preoperative period. In the nondelirium group, the postoperative MDA and GSH-Px levels were found to be lower than preoperative levels, and postoperative SOD levels were found to be higher than preoperative levels. CAT levels were lower in the delirium group when the pre- and postoperative levels were compared in both groups. The postoperative levels of SOD, GSH-Px and CAT in the nondelirium group and MDA in the delirium group were significantly higher than preoperative levels. CONCLUSION: Patients with low preoperative CAT levels appeared to be more susceptible to delirium than patients with higher CAT levels.

[Family functioning in patients with schizophrenia, bipolar affective disorder and epilepsy]. / Sizofreni, Iki Uçlu Duygudurum Bozuklugu ve Epilepsi Hastalarinda Aile Islevlerinin Karsilastirilmasi.

OBJECTIVE: To evaluate the impact of illness progression on the family functioning of patients with schizophrenia, bipolar affective disorder and epilepsy showing chronic relapsing progress and affecting functionality. METHOD: A total of 75 patients who were diagnosed according to DSM-IV criteria as having schizophrenia (n: 25), bipolar affective disorder (n: 25) or epilepsy (n: 25) and their 134 family members were included in the study. A socio-demographical data form was completed by consulting the patient and family members, and a Family Assessment Device (FAD) was used. RESULTS: The general functionality level was low in patients with schizophrenia. Families of patients with bipolar affective disorder had healthier functioning than families of patients with schizophrenia and epilepsy. Subscales of "communication" and "behavioral control" were reported as highly ineffective by the schizophrenia patients. The epilepsy patients have family dysfunction in "behavioral control" and "roles" subscales. The families of bipolar affective disorder patients evaluated their "problem solving" and "general functioning" as problematic. CONCLUSION: The family's experience of disease and adaptation is a dynamic and ongoing process. Our data suggest that chronic psychiatric and neurological diseases may cause some specific difficulties in family functions.

Altered diurnal variation of nitric oxide production in patients with panic disorder.

The aim of this prospective study was to investigate the diurnal change in serum nitric oxide (NO) levels in active and remission phases of patients with panic disorder. This study included 15 patients fulfilling the criteria for panic disorder of Diagnostic and Statistical Manual of Mental Disorders--Fourth Edition and 15 healthy controls matched for age and sex. All patients were receiving a selective serotonin reuptake inhibitor at therapeutic doses. The serum nitrite and nitrate levels of subjects were determined at 10:00 a.m. after overnight fasting and at 3:00 p.m. 2 hours after lunch. NO levels of all patients measured in the morning were significantly higher than those of controls. The patients were also divided into active and remission groups according to clinical status and Panic Agoraphobia Scale's cut-off point. There were no statistically significant differences in serum nitrite and nitrate levels of the active group between the 10:00 a.m. and 3:00 p.m. measurements. In contrast, statistically significant differences were found in the serum levels of nitrite (p<0.05) and nitrate (p<0.05) in the remission group. Notably, the afternoon nitrite and nitrate levels of the remission group were higher than those of the morning levels as seen in control subjects. Thus, diurnal variation of NO production is altered in patients with panic disorder but is resumed in the remission phase. The present study suggests that serum NO levels are a good marker for evaluation of panic disorder.

Topographic abnormalities in event-related potentials in children with monosymptomatic nocturnal enuresis.

AIMS: A functional maturational delay in the central nervous system is dwelled upon in the pathogenesis of monosymptomatic nocturnal enuresis (MNE). In this study we studied whether according to controls N200 and P300, components of the event-related potential (ERP), which is related to aspects of cognitive processing, showed any difference in its topographic distribution in children within the age group 10-13 with monosymptomatic nocturnal enuresis and discussed its relation to the pathogenesis of MNE. METHODS: We performed P300 in 18 patients with MNE and in 16 age-matched healthy subjects. P300 were evoked by an auditory oddball paradigm consisting of 150 tone bursts (80% 1 kHz; 20% 2 kHz). The latencies of the N200 and the P300 waves and the amplitude of the P300 wave were measured. RESULTS: There was no statistical difference between the enuretic group and the controls in N200 and P300 latency and amplitude in the midline frontal (Fz), central (Cz), and parietal (Pz) recording site of the 10-20 International System. In the enuretic group while P300 amplitude in the Fz site was significantly less than the P300 amplitude in the Cz site, there was no statistical difference between the Fz and Pz P300 amplitude values. CONCLUSIONS: When different levels of maturational delay are considered in MNE, it may be claimed that maturational delay in children whose enuresis lasts until older ages will be different from those whose enuresis ends at an early age. The determination of P300 amplitude in parietal records being less in enuretics when compared to the controls may show that there are regional differences in stimuli processing rate/quality.

The indices of endogenous oxidative and antioxidative processes in plasma from schizophrenic patients. The possible role of oxidant/antioxidant imbalance.

There is great evidence in recent years that oxygen free radicals play an important role in the pathophysiology of schizophrenia. The present study was performed to assess the changes in plasma nitric oxide (NO) and thiobarbituric acid-reactive substances (TBARS) levels, and superoxide dismutase (SOD), glutathione peroxidase (GSH-Px), and xanthine oxidase (XO) activities in schizophrenic patients compared to age- and sex-matched normal controls. A hundred patients with schizophrenia and 51 healthy volunteers were included in the study. XO, SOD, and GSH-Px activities as well as NO and TBARS levels were estimated by standard biochemical techniques in the plasma of normal healthy controls and schizophrenia patients. In schizophrenia, increased plasma XO activity (P < .0001) and NO levels (P < .0001), decreased SOD activity (P < .0001), and unchanged GSH-Px activity were detected compared to control group. Plasma TBARS levels were increased in schizophrenic patients (P < .01), especially in the residual subtype. TBARS levels in nonsmoker schizophrenic patients were found to be higher than nonsmoker controls. Although TBARS levels in both patients and controls were found to be higher in smokers as compared to nonsmokers, it was not statistically significant. No effects of duration of the illness, gender, and low and high dose of daily neuroleptic treatment equivalent to chlorpromazine on oxidant and antioxidant parameters were observed. Because the dose and the duration of treatment with drugs have no influence on the results, it can be interpreted that the findings are more likely to be related mainly to the underlying disease. These findings indicated a possible role of increased oxidative stress and diminished enzymatic antioxidants, both of which may be relevant to the pathophysiology of schizophrenia. On the other hand, increased NO production by nitric oxide synthetases (NOSs) suggests a possible role of NO in the pathophysiological process of schizophrenia. These findings may also suggest some clues for the new treatment strategies with antioxidants and NO synthase (NOS) inhibitors in schizophrenia.
