Resting metabolic rate, pulmonary functions, and body composition parameters in children with attention deficit hyperactivity disorder.

PURPOSE: Several studies of school-aged children with attention deficit hyperactivity disorder (ADHD) have found a higher prevalence of overweight/obesity compared with the general population. However, the scientific literature contains insufficient evidence to establish clear conclusions on pulmonary functions, resting metabolic rate (RMR), and body composition in children with ADHD. This study therefore investigates the pulmonary functions tests (PFTs), RMR, and body composition parameters in children with ADHD and evaluates their quality of life. METHODS: Forty children with ADHD and 40 healthy controls participated in the study. The children's parents completed Conners' parent rating scale (CPRS) and the pediatric quality of life (PedsQL), and their teachers completed Conners' Teacher rating scale (CTRS). The child participants also completed the PedsQL. RMR, PFTs, and body composition parameters were investigated. RESULTS: No significant differences in age, gender, and socioeconomic level were found. All CPRS subscales, except anxiety and psychosomatic conditions, were significantly different (p < 0.05). According to the CTRS, inattentiveness, hyperactivity, and conduct problems were significantly higher in the ADHD group. The results showed that the ADHD group's quality of life is worse than the control group. Body mass index, body composition parameters, RMR, and PFTs were not statistically different between the children with ADHD and the healthy controls. CONCLUSIONS: Further studies with complex designs are needed to confirm the results.

The Perceived Stigma in Patients with Alopecia and Mental Disorder: A Comparative Study.

AIM: We aimed to measure the perceived stigma, especially in patients with alopecia areata (AA) and to compare the results with patients with mental disorder (MD). MATERIALS AND METHODS: This study included forty patients with AA who were consecutively recruited from dermatology outpatient clinic and 42 patients with MD who were consecutively recruited from psychiatric outpatient clinic. The presence of a MD was assessed by the Diagnostic and Statistical Manual of Mental Disorder Fourth Edition. All participants were asked to complete the 28 items modified stigmatization questionnaire. RESULTS: Total and all subscale scores of stigmatization questionnaire scale were higher in the group of patients with AA than in the patients with MD. CONCLUSION: AA is a condition that leads to more self-stigmatization than MD.

The antioxidant and antiapoptotic effects of crocin pretreatment on global cerebral ischemia reperfusion injury induced by four vessels occlusion in rats.

AIMS: Cerebral ischemia reperfusion (IR) injury is a process in which oxidative and apoptotic mechanisms play a part. Neuroprotective agents to be found could work out well for the efficient and safe minimization of cerebral IR injury. Crocin is a strong antioxidant agent; however the influence of this agent on the experimental cerebral ischemia model has not been studied extensively and thus it is not well-known. The objective of our study was to investigate the antioxidant, antiapoptotic and protective effects of crocin on the global cerebral IR induced by four-vessel occlusion. MAIN METHODS: A total of 30 adult female Sprague-Dawley rats were equally and randomly separated into three groups as follows: sham, IR and IR+crocin (40mg/kg/day orally for 10days). 24h after electrocauterization of bilateral vertebral arteries, bilateral common carotid arteries were occluded for 30min and reperfused for 30min. Oxidative stress parameters (TAS, TOS, OSI), haematoxylin and eosin staining, caspase-3 and hypoxia-inducible factor-1 alpha (HIF-1α) expressions and TUNEL methods were investigated. KEY FINDINGS: There was a significant difference between the IR and sham groups by means of OSI level, histopathological scoring, caspase-3, HIF-1α and TUNEL-positive cell parameters. We have also observed that pre-treatment with crocin reduced these parameter levels back to the baseline. SIGNIFICANCE: The data obtained from the present study suggest that crocin may exert antiapoptotic, antioxidant and protective effects in IR-mediated brain injury induced by four-vessel occlusion. To the best of our knowledge, this would be the first study to be conducted in this field.

Frequency of body dysmorphic disorder among patients with complaints of hair loss.

BACKGROUND: Body dysmorphic disorder (BDD) is a psychiatric condition in which a disabling preoccupation with a non-existent or slight defect in appearance is the main symptom. Hair concerns are frequent in patients with BDD. OBJECTIVES: The purpose of this study was to determine the prevalence of BDD among patients with complaints of hair loss. METHODS: A validated BDD questionnaire (BDDQ) was administered to 150 patients with complaints of hair loss and 150 control subjects who were selected from among general dermatology (GD) patients. Standard statistical tests were performed (descriptive analysis, chi-squared tests, non-parametric tests). Differences that achieved a P-value of <0.05 were considered statistically significant. RESULTS: Among patients with complaints of hair loss, 42 of 142 subjects retained in the study (29.6%; 31 females and 11 males) were diagnosed with BDD. Furthermore, 25.6% of female patients and 52.4% of male patients were diagnosed with BDD (P = 0.013). Hair concerns were more common in males than in females (P < 0.05). In the GD group, four control subjects (2.7%, all female) were diagnosed with BDD; all of their concerns focused on the body and acne. CONCLUSIONS: The incidence of BDD is about 10 times higher in patients with complaints of hair loss than it is in GD patients and is higher in males. Awareness of the condition and the referral of selected patients to mental health professionals is crucial.

Disordered eating attitudes, alexithymia and suicide probability among Turkish high school girls.

We aimed to examine association between disordered eating attitudes (DEAs), alexithymia and suicide probability among adolescent females and to explore potential link between alexithymia and suicide probability in subjects with DEAs. 381 female students completed Eating Attitude Test (EAT-26), Toronto Alexithymia Scale (TAS-20) and Suicide Probability Scale (SPS). It was found that 13.2% (n=52) of the subjects have DEAs. Results indicated that total TAS-20 score and scores of Difficulty in Identifying Feelings (DIF) and Difficulty in Describing Feelings (DDF) subscales were significantly higher in DEAs group than in those non DEAs group (p<0.05). Additionally, total SPS score (p<0.001), Hopelessness (p=0.001), Suicide Ideation (p<0.001) and Hostility (p=0.003) subscales scores of SPS were significantly higher in the alexithymic DEAs than the non-alexithymic DEAs group. In order to control potential effect of depression, SPS subscales were used as covariate factors in ANCOVA. Negative Self-Evaluation subscale yielded a statistically significant difference between groups, other subscales did not. Results point out these; DEAs are relatively frequent phenomenon among female students in Turkey and presence of alexithymia was associated with an increased suicide probability in adolescents with DEAs. The results should be evaluated taking into account that depressive symptomatology was not assessed using a depression scale.

A child death as a result of physical violence during toilet training.

Enuresis and delayed bladder control are a common source of psychosocial concern for both parents and children. Different cultures have different norms with regard to parenting attitudes. The fact that in Turkey, parents consider enuresis or encopresis as a sign of laziness, misbehavior, or disobedience rather than a medical disorder may cause children to be exposed to physical and emotional violence and maltreatment by the family as a corrective strategy. We present a case in this paper which had a fatal outcome due to physical violence against a child as an educational measure and a toilet training method.

Evaluation of physical fitness parameters in patients with schizophrenia.

The aims of this study were to compare aerobic and anaerobic exercise capacities, pulmonary functions, body composition and fat distribution parameters in patients with schizophrenia and healthy controls and to investigate the associations among these parameters. Sixty (30 male, 30 female) patients with schizophrenia and 60 (30 male, 30 female) healthy controls were included in the study. Maximal aerobic capacity was estimated with the Astrand submaximal exercise protocol, and anaerobic performance was determined with a Wingate test. Body composition was established with a bioelectrical impedance analyzer. Pulmonary function tests, skinfold thickness and body circumference measurements were also carried out. Maximal aerobic capacity, maximal anaerobic power, anaerobic capacity and pulmonary function tests (forced vital capacity and maximal voluntary ventilation) were found to be lower in male and female schizophrenic groups as compared to the controls. Body fat percentage, waist and abdomen circumferences, and waist to hip ratio were found to be higher in female schizophrenic patients than in controls. We suggest that maximal aerobic capacity, maximal anaerobic power, and anaerobic capacity are poor in the schizophrenia patients as compared to healthy controls. Low cardiorespiratory fitness is related to reduced pulmonary function and impaired body composition in schizophrenia patients.

Relationship of Internet addiction with impulsivity and severity of psychopathology among Turkish university students.

The previous studies have found a relationship between IA and both impulsivity and psychopathology when they were considered separately. The aim of this study was to investigate the relationship of Internet addiction (IA) with impulsivity and severity of psychopathology among Turkish university students. We also wanted to control the effect of impulsivity dimensions on the relationship between IA and psychopathology. A total of 319 university students from two universities in Ankara participated to the study. Students were assessed through the Internet Addiction Scale (IAS), the Symptom Checklist-Revised (SCL-90-R) and the Barratt Impulsiveness Scale-11 (BIS-11). Correlational analyses revealed that severity of IA was related to both SCL-90-R and BIS-11 scores. Among SCL-90-R subscales, severity of obsessive-compulsive symptoms (OCS) was the only predictor for IAS score. Hierarchical regression analysis indicated that interpersonal sensitivity, additional to attentional and motor impulsiveness, was the predictor of IAS score. Although severity of IA is associated with wide range of psychopathology, particularly OCS, interpersonal sensitivity seems to be the main dimension that predict severity of IAS additional to impulsiveness (attentional and motor). Impulsivity seems to be an important construct when considering IA and its treatment among Turkish university students.

Relationship of internet addiction severity with depression, anxiety, and alexithymia, temperament and character in university students.

The aim of the study was to investigate the relationship of Internet addiction (IA) severity with alexithymia, temperament, and character dimensions of personality in university students while controlling for the effect of depression and anxiety. A total of 319 university students from two conservative universities in Ankara volunteered for the study. Students were investigated using the Toronto Alexithymia Scale-20, the Temperament and Character Inventory, the Internet Addiction Scale, the Beck Anxiety Inventory, and the Beck Depression Inventory. Of the university students enrolled in the study, 12.2 percent (n=39) were categorized into the moderate/high IA group (IA 7.2 percent, high risk 5.0 percent), 25.7 percent (n=82) were categorized into the mild IA group, and 62.1 percent (n=198) were categorized into the group without IA. Results revealed that the rate of moderate/high IA group membership was higher in men (20.0 percent) than women (9.4 percent). Alexithymia, depression, anxiety, and novelty seeking (NS) scores were higher; whereas self-directedness (SD) and cooperativeness (C) scores were lower in the moderate/high IA group. The severity of IA was positively correlated with alexithymia, whereas it was negatively correlated with SD. The "difficulty in identifying feelings" and "difficulty in describing feelings" factors of alexithymia, the low C and high NS dimensions of personality were associated with the severity of IA. The direction of this relationship between alexithymia and IA, and the factors that may mediate this relationship are unclear. Nevertheless, university students exhibiting high alexithymia and NS scores, along with low character scores (SD and C) should be closely monitored for IA.

Alexithymia and personality in relation to social anxiety among university students.

The aims of the present study were to investigate the relationship of social anxiety symptoms with alexithymia and personality dimensions in university students and to control the effects of depression and anxiety on this relationship. A total of 319 university students (85 males and 234 females) from two different universities in Ankara were investigated with the Liebowitz Social Anxiety Scale (LSAS), the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), the Toronto Alexithymia Scale (TAS-20) and the Temperament and Character Inventory (TCI). We found that subscales of the LSAS (fear or anxiety and avoidance) were positively correlated with depression and alexithymia and "difficulty in identifying feelings" (DIF) and "difficulty in describing feelings" (DDF) subscales of the TAS-20. Harm avoidance (HA) showed positive correlations with subscales of the LSAS, whereas self-directedness (SD) showed negative correlations with these subscales. High TAS-20 DDFand HA and low SD predicted fear or anxiety LSAS subscale scores, whereas high TAS-20 DDF, HA and depression scores were predictors for LSAS avoidance subscale scores. Although our sample is not representative of the whole Turkish university student population, we conclude that both fear or anxiety and avoidance were mainly interrelated with DDF and HA, although the causal relationship is not clear.

Association of schizophrenia with T102C (rs6313) and 1438 A/G (rs6311) polymorphisms of HTR2A gene.

OBJECTIVE: The aim of this study is to investigate whether there were any associations between the T102C and 1438 A/G polymorphisms of the 5-HT2A receptor gene and schizophrenia. We conducted a case-control study of the T102C and 1438 A/G polymorphisms in Turkish patients. METHODS: We compared genotypes and allele frequencies of T102C and 1438 A/G polymorphisms of 5-HT2A receptor gene in 102 patients with schizophrenia diagnosed, according to DSM-IV, and 107 healthy controls. Genotyping was performed by real-time polymerase chain reaction. RESULTS: We found no significant association between schizophrenia and genotypic or allele frequencies of HTR2A gene 102T/C (rs6313) and 1438 A/G (6311) polymorphisms. However, comparison of HTR2A gene 102 T/C and 1438 A/G polymorphisms in terms of genotypic and allele frequencies between the two patient groups, with or without a family history of schizophrenia, shows that T- and A-allele frequencies were significantly higher (p < 0.05) in the case group that has a history of schizophrenia in their family. CONCLUSION: In conclusion, our results do not support the hypothesis that the T102C and 1438 A/G polymorphisms in the 5-HT2A receptor gene are associated with schizophrenia, but further studies in a larger sample are needed.
