This study aimed to determine the frequency of posttraumatic stress disorder (PTSD) in a group of search and rescue workers 2 months after the May 2003 Bingol earthquake. Forty-four of 55 workers were interviewed. The Personal Information Form, the Clinician Administered Posttraumatic Stress Disorder Scale, the State Anxiety Inventory, the Trait Anxiety Inventory, the Beck Depression Inventory, the Quality of Life Enjoyment and Satisfaction Questionnaire, and the Endicott Work Productivity Scale were used. PTSD was diagnosed in 25% of the subjects. In subjects with PTSD, all scale scores were significantly higher. A positive correlation was determined between Clinician Administered Posttraumatic Stress Disorder Scale score and State Anxiety Inventory, Trait Anxiety Inventory, Beck Depression Inventory, Endicott Work Productivity Scale scores (r = 0.712, p = .000; r = 0.429, p = .004; r = 0.381, p = .011; r = 0.720, p = .000, respectively). The high scores of all scales showed that PTSD may also have comorbidity with other psychiatric disorders. Rescue workers who give first-level service in disasters should receive psychiatric support in specific time frames.

In recent years, there has been an increasing focus on generalized anxiety disorder (GAD) which is one of the most prevalent mental disorders in general population. Psychological, genetic, neurobiological, and neurochemical factors are believed to play role in the etiopathogenesis of GAD. The role of oxidative stress, as a neurochemical cause, in various anxiety disorders has been studied in recent years; however, it has not been thoroughly studied in GAD, yet. In this paper, we aimed to evaluate the serum levels of lipid hydroperoxide (LOOH), paraoxonase, and arylesterase in GAD patients without any co-morbid psychiatric disorders and investigate their diagnostic performance. Blood samples were collected from 40 GAD patients and 40 healthy control subjects to measure their serum LOOH levels, arylesterase and paraoxonase activities. Obtained results have been compared between groups and receiver operating characteristic (ROC) curve has been drawn for diagnostic performance of measured biochemical markers. Positive and negative predictive values have been estimated where appropriate. Mean LOOH level of the GAD patients was significantly higher than that of control subjects (t=-5.49, p<0.001), whereas, mean paraoxonase activity was lower in these patients (t=3.056, p=0.03). GAD could be predicted for LOOH level over 7.740 μmol/l with 92.5% positive predictive value and 92% negative predictive value. Increased LOOH level and decreased paraoxonase activity of GAD patients may suggest increased lipid peroxidation and oxidative stress in these patients. LOOH levels may be a state marker for diagnosing GAD.

Studies attempting to clarify the relationship between major depressive disorder (MDD) and the immune system have been increasing in recent years. It was reported that increased production of the main proinflammatory cytokines, such as interleukin-1, interleukin-6, and tumor necrosis factor-alpha, and that of acute phase reactants may play a role in the etiopathogenesis of depression. Stress and depression were reported to increase leukocyte and neutrophil counts and to decrease lymphocyte count. Biological determinants affecting the diagnosis, therapy, and prognosis of depression are quite limited. Therefore, new etiological models are needed to explain the pathophysiology of depression. In recent years, neutrophil–lymphocyte ratio (NLR) was determined to be a good indicator of inflammatory status. There is no study in the literature investigating NLR in MDD. This study aims to examine the role of inflammation in the etiology of depression based on the NLR in MDD patients who are undergoing no pharmacological therapy. A total of 41 patients diagnosed with MDD, who received no antidepressant therapy within the past 1 month, were included in the study, which took place between January and March 2015. The control group consisted of 47 healthy subjects with no psychiatric disorders. A sociodemographic information form and a Beck Depression Scale were administered, and the blood was taken for biochemical analysis. Significant differences were identified in the NLR, neutrophil count, lymphocyte percentage, and leukocyte values of the patient group when compared with the control group (P<0.05). Our study is the first in which NLR was investigated in MDD. The findings of the study reveal that NLR tends to be higher in patients with MDD, and a high NLR value supports the view that inflammation is a critical factor in the etiology of MDD.

Acne is an easily recognizable abnormality which may cause some adverse psychosocial consequences. We aimed to determine the social phobia frequency, social anxiety level, and disease related disability in a group of acne vulgaris patients. One-hundred and forty acne vulgaris patients and 98 healthy control subjects were included in the study. Acne severity was determined by the Global Acne Grading System (GAGS). A psychiatrist interviewed each participant and the Liebowitz Social Anxiety Scale (LSAS) was administered to all participants, who also completed the Hospital Anxiety and Depression Scale (HADS) and Sheehan Disability Scale (SDS). Social phobia was diagnosed in 45.7% of acne vulgaris patients and in 18.4% of control subjects. Acne vulgaris patients demonstrated higher performance avoidance and total avoidance scores in LSAS than controls. Acne vulgaris patients without social phobia had higher scores in HADS and LSAS than the acne vulgaris patients with social phobia. They were more disabled in their occupational, social, and familial lives. Social phobia diagnosis predicted disability at work, whereas education level predicted the disability in family life of acne vulgaris patients. Social phobia seems to be a common psychiatric comorbidity which may give rise to some additional disability among acne vulgaris patients.

We investigated whether prolidase activity has a diagnostic test value in schizophrenia and assessed the relation between prolidase activity and sociodemographic-clinical characteristics of patients with schizophrenia. Fifty patients with schizophrenia (diagnosed as schizophrenia according to DSM-V criteria) and 50 healthy volunteers were included in this study. Case and control groups had a similar distribution in age, sex, body mass index (BMI), and smoking status. Serum prolidase activity was measured in both groups and was determined to be significantly higher in the patient group (509.706±41.918) compared to the control group (335.4±13.6; t=6.231; p=0.0001). A cut-off point of 392.65U/L prolidase was determined for diagnostic measures from the plotted ROC curve. The area under the ROC curve was 1.000, which was significant (p<0.0001). Higher values were assigned as the disease state. Both positive predictive value (PPV) and negative predictive value (NPV) were 100% at the cut-off point of 392.650U/L. The prolidase levels of the control group were all below the cut-off point. There were no statistically significant differences between the two groups with regard to age, gender, or BMI (p>0.05), and no correlation was found between mean prolidase activity and age of onset of the disease, family history, disease duration, number of hospitalizations, subtypes of schizophrenia, PANSS scores or sub-scores, CGI-S scores, S-A scale scores, and the antipsychotic treatment (p>0.05). The results of this study indicate that serum prolidase activity may be a useful diagnostic test for schizophrenia; however, further studies are needed to verify this.

ABSTRACT Objective: To compare the longer-term outcomes of pharmacological treatment of patients with a diagnosis of bipolar affective disorder currently suffering a manic or hypomanic episode prescribed olanzapine or non-olanzapine medication in naturalistic, clinical practice settings in Bosnia-Herzegovina, Slovakia, Slovenia, Turkey, Saudi Arabia and Egypt. Research design and methods: Prospective, observational, non-interventional study conducted over 9 months. Inpatients or outpatients who initiated or changed oral bipolar mania medication were grouped into (1) those prescribed olanzapine at baseline (n = 569) and (2) those not prescribed olanzapine (n = 325). Main outcome measure(s): The change from baseline in the Clinical Global Impression Severity scale for bipolar disorder (CGI-BP-S), the rates of symptomatic response and remission (based on CGI-BP-S) and the frequency and nature of treatment-emergent adverse events. Analyses included (1) linear or logistic regression, with adjustment for confounders, based on the last observation carried forward and (2) weighted repeated measures models that adjusted for treatment switching and patient drop-out. Results: When results were adjusted for treatment switching and patient drop-out, patients prescribed olanzapine had significantly better CGI-BP-S scores (mean difference = −0.24; 95% confidence interval [CI] −0.33, −0.16; p < 0.001) and significantly greater odds of treatment response (odds ratio [OR] = 1.86; 95% CI 1.31, 2.65; p < 0.001) and symptom remission (OR = 1.65; 95% CI 1.18–2.32; p = 0.003) than those not prescribed olanzapine. The frequency of most adverse events decreased in both groups. Patients prescribed olanzapine had significantly greater weight gain from baseline (mean increase = 2.66 kg; 95% CI 2.35, 2.98) compared with those not prescribed olanzapine (mean increase = 1.85 kg; 95% CI 1.51, 2.19; p < 0.001). Conclusions: Inclusion of olanzapine is of benefit for pharmacological treatment of patients with bipolar disorder. However, the favourable outcomes observed cannot be directly attributed to olanzapine alone because of the high prevalence of polypharmacy in the patient population.

Background Suicide is an important health problem in Turkey as it is in all regions of the world. Suicidal behavior has multiple causes, which are broadly divided into those related to proximal stressors and those due to predisposition. Suicide statistics may be associated with mental health disorders, which are among the foremost predictors of suicide attempts. More than 90% of patients who commit suicide have a diagnosable psychiatric disorder, usually a major depressive disorder. Other major risk factors for suicide attempts are history of suicide attempts in the family, stressful life events, sleep disturbances, poor income, unemployment, severity of symptoms of depression, and anxiety. Sleep is a complex phenomenon. Sleep disturbances can therefore be contributed to the emergence of suicidal behavior allowing for the possibility of predicting future suicides. Methods We evaluated 106 patients who were admitted after suicide attempts to the Department of Psychiatry at Dicle University Faculty of Medicine. The recruited subjects were assessed by Structured Clinical Interview for DSM-IV Axis I disorders, and the intensity of symptoms was evaluated using the Beck Anxiety Inventory, Hamilton Depression Rating Scale, and Pittsburgh Sleep Quality Index. The mean values of the subjects attempting multiple and single suicides were compared using appropriate inferential statistical tests. Results Most suicide attempts are believed to be preventable. Our results revealed that a great variety of risk factors are associated with an increased risk for multiple suicide attempts. Most of these attempts appeared to be spontaneous and impulsive rather than planned. In particular, this study highlights the importance of previous suicide attempts, history of suicide in the family, history of stressful life events in the previous 6 months, poor income, unemployment, sleep disturbances, severe hopelessness with depression, and coexisting symptoms of anxiety as risk factors. Conclusion The first step in prevention of suicides is doubtlessly strong and reliable communication, due to the fact that the majority of subjects who commit suicide have had contact with a health professional during the month before the suicide.

Objective: To evaluate the changes in psychological distress level and quality of life (QoL) scores of keratoconus (KC) patients 1 year after corneal collagen cross-linking (CXL). Methods: Observational cross-sectional study. Thirty-three, consecutive progressive KC patients who received CXL treatment were enrolled in the study. All patients were evaluated before and 1 year after CXL ophthalmologically and psychologically. Main outcome measures were the visual, refractive, and topographic changes and the Beck Depression Inventory, State-Trait Anxiety Inventory (STAI), Short Form-36 (SF-36), and The National Eye Institute Visual Function Questionnaire (NEI-VFQ-25). Results: There were significant improvements in the keratometric readings at flat axis, steep axis, the mean keratometric reading, the corneal astigmatism (Kast), and the maximum keratometric reading. State-Trait Anxiety Inventory-II scores, QoL dimensions, such as physical role difficulty, general health, mental health, ocular pain, near activities, distance activities, peripheral vision, and mental health scores, and the composite score of NEI-VFQ-25, were higher after surgery. There was a positive correlation between the changes observed in Kast and mental health; a negative correlation between the changes in Kast and STAI-II, and a negative correlation between the changes in mental health and STAI-II. Change in STAI-II has significantly predicted the improvement observed in general health. Conclusions: Our results suggested lower trait anxiety and better vision-related and health-related QoL in KC patients 1 year after successful CXL treatment. Better QoL in these patients seems to be related not only with the visual and refractive results but also improvement observed in trait anxiety.

Suicide attempt with paliperidone overdose: a case report Suicide is a common problem seen in patients with schizophrenia. Taking overdoses of drugs is a well-known way for committing suicide. We report a case with schizophrenia, who attempted suicide with 243 mg. of paliperidone, a recently marketed atypical antipsychotic, and admitted to our emergency service with restlessness, agitation, mild confusion, and disorganized behavior. Gastric lavage, hydration, and 72 hours monitorization of the patient in intensive care unit ended without any sequelae. Our case, in addition to the limited available data, suggests paliperidone is a relatively safe drug in its overdoses.

Objective: The aim of this study is to investigate the presence of ADHD and other psychiatric disorders among parents with at least one child with ADHD relative to parents with children who do not have ADHD. Method: Eighty five parents of children with ADHD with 68 control parents who had healthy children without ADHD were interviewed for participation in present study. Each parent was evaluated for co-existing psychiatric disorders using the Structured Clinical Interview for the DSM IV Axis I Disorders (SCID I). Results: We found that ADHD and co-morbid psychiatric symptoms were increased in the parents of children with ADHD in comparison with the healthy control group. Conclusion: Psychiatric co-morbidity was more common among the parents of patients with inattentive and combined presentations. Adult ADHD is associated with psychiatric co-morbidities including anxiety disorders, mood disorders, and somatoform disorders as well as substantial role impairment.
