1H-magnetic resonance spectroscopy in first episode and chronic schizophrenia patients

Background/aim: The aim of this study was to compare metabolite levels of the dorsolateral prefrontal cortex (DLPFC), anterior cingulate gyrus (ACG), thalamus, and hippocampus in patients with chronic schizophrenia (CSPs) and first psychotic episode patients (FEPs) by the use of magnetic resonance spectroscopy (MRS). Materials and methods: Thirty CSPs, 20 FEPs, and 30 healthy subjects participated in this study. N-Acetylaspartate (NAA), creatine, choline (Cho), and myoinositol levels of the DLPFC, ACG, thalamus, and hippocampus were measured by 1H-MRS. Results: It was determined that the NAA/Cho ratio was lower in both the FEPs and CSPs than the healthy controls in the DLPFC. DLPFC Cho levels were also higher in CSPs than healthy controls. NAA levels in CSPs were significantly lower than in the control group in the hippocampus. There was no significant difference in neurometabolite levels and ratios in the ACG and thalamus between the groups. Conclusion: This study supports neuronal dysfunction or loss of neuronal integrity in the DLPFC and hippocampus in CSPs. FEPs showed less neuronal dysfunction in the DLPFC, but not in the hippocampus. Our results suggest that schizophrenic patients show brain metabolic changes with the onset of the disorder in the DLPFC; these changes could be more apparent in the hippocampus as the disease progresses to chronic stages. © TÜBİTAK

Practice of Acute and Maintenance Electroconvulsive Therapy in the Psychiatric Clinic of a University Hospital from Turkey: Between 2007 and 2013

Objective: Electroconvulsive therapy (ECT) can be given as the form of acute, continuation or maintenance ECT according to the process of administration. We report our 7 years' observation with acute and maintenance ECT in a university hospital in Turkey. Methods: The medical records of the hospitalized patients treated with acute or maintenance ECT between the years 2007 and 2013 was retrospectively analyzed. The sociodemographic characteristics, diagnosis, data of ECT and the co-administered psychotropic drugs were recorded. The frequency of ECT was calculated by identifying the total number of the hospitalized patients during the study period from the hospital records. Results: A total number of 1,432 female and 1,141 male patients hospitalized in a period of 7 years, with a total number of 111 patients treated with ECT. The ratio of ECT was 4%, maintenance/acute ECT 11%. For acute ECT, affective disorders (65.3%) and psychotic disorders (21.6%) were among the leading diagnoses. Maintenance ECT, the diagnosis was; 6 affective disorders, 4 psychotic disorders and 1 obsessive compulsive disorder. There was a significant difference between the patients receiving acute and maintenance ECT in terms of age, duration of illness, and number of previous hospitalizations and ECTs. Conclusion: The percentage of patients treated with acute ECT is lower in our institution than that in many other institutions from our country. Acute and maintenance ECT should be considered as an important treatment option particularly for patients with long disease duration, a high number of hospitalizations and a history of benefiting from previous ECTs.

Pulmonary thromboembolism due to paliperidone: Report of 2 cases

Venous thromboembolism (VTE) is serious medical condition, which might be caused by psychotropic medications. Previously, antipsychotic-induced VTE due to olanzapine, risperidone, clozapine, and amisulpiride was reported. In this report, we present 2 cases of paliperidone-induced VTE. © 2014 Elsevier Inc.

Association between suicidal ideation and behavior, and depression, anxiety, and perceived social support in cancer patients

Background: The aim of this study was to determine the relationship between suicidal behavior and associated factors such as depression, anxiety, and perceived social support level in cancer patients. Material/Methods: The study group included 102 patients who were under treatment in the oncology department and the control group included 100 individuals with similar sociodemographic features. A sociodemographic information form, Beck depression inventory, Beck anxiety inventory, suicidal behavior inventory, suicidal ideation inventory, and multidimensional inventory of perceived social support were used. Results: The mean Beck depression inventory and Beck anxiety inventory scores in the study group were significantly higher compared to the control group. Thirteen patients in the study group attempted suicide, whereas 3 individuals attempted suicide in the control group. Similarly, the mean suicide behavior and ideation scores in the study group were significantly higher compared to the control group. The mean total multidimensional inventories of perceived social support score, as well as the mean family and friend sub-inventory scores in the control group were significantly higher compared to the study group. Conclusions: This study revealed that depression and anxiety occur frequently in cancer patients. Suicide attempts and ideation are higher in cancer patients compared to the control group. Social support perceived from family and friends is lower in cancer patients. Suicide attempts are correlated with depression, anxiety, low level of perceived social support, and advanced disease stage. © Med Sci Monit, 2014
