Temperament traits and psychopathy in a group of patients with antisocial personality disorder.

OBJECTIVE: The Psychopathy Checklist Revised (PCL-R) and Temperament and Character Inventory (TCI) have been used extensively in research of personality disorders; however, no previous study has investigated the relation between psychopathy factors and temperament and character traits in patients with antisocial personality disorder (ASPD). Our aim was to fill this gap in the literature. METHODS: The PCL-R Factor scores and the TCI temperament and character scores were evaluated in 68 men with ASPD and 65 healthy male controls. RESULTS: The ASPD cases had significantly higher PCL-R Factor 1, Factor 2, and Total scores, as well as significantly higher TCI Novelty Seeking and Harm Avoidance scores, whereas the control group had higher TCI Reward Dependence, Persistence, Self-Directedness, and Cooperativeness scores. Correlation analysis revealed that, in the whole study group, PCL-R Factor 1, Factor 2, and Total scores were positively correlated with Novelty Seeking and Harm Avoidance scores and negatively correlated with Reward Dependence, Persistence, Self-Directedness, and Cooperativeness scores. When each group was analyzed separately, the correlations were not significant. Regression analysis supported the main findings. CONCLUSION: Our results showed that both PCL-R Factor 1 score, which is claimed to reflect "core psychopathy," and PCL-R Factor 2 score, which reflects criminal behaviors, were positively correlated with Novelty Seeking and Harm Avoidance and were negatively correlated with Reward Dependence in the whole sample. The reduced variance of PCL-R in each group might lead to nonsignificant associations within groups. Without the subjects with severe psychopathy in the present study, it might not be possible to show the association.

Synaptosomal-associated protein 25 gene polymorphisms and antisocial personality disorder: association with temperament and psychopathy.

OBJECTIVE: The molecular genetic of personality disorders has been investigated in several studies; however, the association of antisocial behaviours with synaptosomal-associated protein 25 (SNAP25) gene polymorphisms has not. This association is of interest as SNAP25 gene polymorphism has been associated with attention-deficit hyperactivity disorder and personality. METHODS: We compared the distribution of DdeI and MnII polymorphisms in 91 young male offenders and in 38 sex-matched healthy control subjects. We also investigated the association of SNAP25 gene polymorphisms with severity of psychopathy and with temperament traits: novelty seeking, harm avoidance, and reward dependence. RESULTS: The MnII T/T and DdeI T/T genotypes were more frequently present in male subjects with antisocial personality disorder (APD) than in sex-matched healthy control subjects. The association was stronger when the frequency of both DdeI and MnII T/T were taken into account. In the APD group, the genotype was not significantly associated with the Psychopathy Checklist-Revised scores, measuring the severity of psychopathy. However, the APD subjects with the MnII T/T genotype had higher novelty seeking scores; whereas, subjects with the DdeI T/T genotype had lower reward dependence scores. Again, the association between genotype and novelty seeking was stronger when both DdeI and MnII genotypes were taken into account. CONCLUSION: DdeI and MnII T/T genotypes may be a risk factor for antisocial behaviours. The association of the SNAP25 DdeI T/T and MnII T/T genotypes with lower reward dependence and higher novelty seeking suggested that SNAP25 genotype might influence other personality disorders, as well.

The Relationship of Smartphone Addiction and Alexithymia.

OBJECTIVE: This study aims to evaluate whether smartphone addiction (SA) is associated with social media use and alexithymia levels in university students. METHODS: A group of 935 students aged between 18 and 45 years (509 females and 426 males) was recruited from different universities in Istanbul. SAs, alexithymia and social media use were assessed using the Smartphone Addiction Scale Short Version (SAS-SV), Toronto Alexithymia Scale-20 (TAS-20), and ad-hoc questions regarding social media use. RESULTS: The mean age of participants was 21.89±3.27 years and 509 of participants were female (54.4%). 455 (48.6%) participants were placed in the "SA" and 198 (21.2%) in the "alexithymia" categories. The study found a high level of positive correlation (p<0.001) between both subscale and total TAS-20 scores and SAS-SV scores. Gender (OR=1.496, 95% CI 1.117-2.002, p=0.007) and number of social media by participants (OR=1.221, 95% CI 1.134-1.315, p<0.001) and TAS (OR=1.074, 95% CI 1.059-1.090, p<0.001) were found to be an independent predictors for SA. CONCLUSION: The study revealed a positive correlation between alexithymia and smartphone use severity, and alexithymia was a significant predictor of SA. Future studies focusing on the causal aspect of this relationship will be useful in planning strategies for treatment.

Epileptic seizure during anaesthesia induction with etomidate.

In this report a 20-year-old male patient who had suffered tonic-clonic seizure after a single induction dose of etomidate until a bispectral index value of 60 is presented. Our best knowledge, this case is the first report of pure etomidate (with induction dose) induced generalized tonic clonic seizure proven with EEG. Anaesthesiologists should be careful against such a complication even in the induction stage of anaesthesia during etomidate use.

Accompaniment of Tourette syndrome and neuropsychiatric symptoms.

Tourette syndrome (TS) is a neuropsychiatric disorder characterized by multiple motor tics and one or more vocal tics. Attention deficit, obsessive-compulsive disorder, personality problems, and impulsivity may be associated with TS. Functional neuro-imaging studies indicate that the ventral striatum is the most affected brain area in TS. We report a case with TS who had cerebellar atrophy, cerebellar arachnoid cyst, bilateral congenital triangular alopecia, bilateral strabismus, and oxycephaly. The association among these symptoms and TS is rare, and the possible relationship of these symptoms should be investigated with further studies.

Effects of diagnostic comorbidity and dimensional symptoms of attention-deficit-hyperactivity disorder in men with antisocial personality disorder.

OBJECTIVE: Although children with attention deficit hyperactivity disorder (ADHD) are at increased risk for later onset of antisocial personality disorder (APD) as adults, the utility of ADHD as either a comorbid diagnosis (ADHD(c)) or dimensional symptoms (ADHD(d)) in predicting behaviour and substance use problems in APD subjects has not been examined. METHOD: A total of 105 adult male offenders with Structured Clinical Interview for Axis II Disorders (SCID-II)-based DSM-III-R APD were studied in terms of: (i) psychopathy scores on the Hare Psychopathy Checklist-Revised (PCL-R); (ii) ADHD(c) diagnostic comorbidity on clinically administered DSM-IV questionnaire; and (iii) ADHD(d) dimensional symptoms by means of Wender Utah Rating Scale (WURS) and Conners Adult ADHD Rating Scale (CAARS) during a 12 month study period (May 2005-May 2006). RESULTS: Sixty five per cent of APD subjects met criteria for ADHD(c) diagnostic comorbidity with significantly increased rates of childhood neglect, parental divorce and suicide attempt, but not of psychopathy. APD subjects with ADHD(d) symptoms were noted to have earlier onset and increased rate of self-injurious behaviour (SIB), suicide attempt, and psychopathy. The psychopathy scores, in turn, were predictive of earlier onset of SIB and behavioural problems. CONCLUSION: Both ADHD(c) diagnostic comorbidity and ADHD(d) symptoms need to be assessed in APD subjects and the dimensional measures may be better in detecting earlier onset SIB, suicide attempt and other behavioural problems.

Self-mutilating behavior in patients with dissociative disorders: the role of innate hypnotic capacity.

BACKGROUND: Despite the fact that the assumption of a relationship between self-mutilation and dissociative disorders (DD) has a long history, there is little empirical evidence to support this premise. The present study examined this relationship and investigated whether this commonality is associated with innate hypnotic capacity. METHODS: Fifty patients diagnosed with DD and 50 control subjects with major depression were assessed by using a self-mutilation questionnaire, Dissociative Experiences Scale, Traumatic Experiences Checklist, and the Eye-Roll Sign for their self-mutilating behaviors, dissociative symptoms, early trauma, and innate hypnotic capacity, respectively. RESULTS: We have found that 82% of the present sample of patients with DD injured themselves. They had higher scores on trauma, dissociation and eye-roll measurements than controls. In addition, DD patients with self-mutilation were more likely to have high scores of trauma, dissociation and eye-roll than those without self-mutilation. Innate hypnotic capacity was a strong predictor of self-mutilating behavior in DD patients. CONCLUSIONS: This study strongly supports the assumption that patients with DD are at high risk for self-mutilating behavior and points to the necessity of routine screening for self-mutilating behavior as well as the hypnotic capacity which may constitute a high risk for self-injury in this patient group.

[The relationship between subjective sleep quality and aggression in male subjects with antisocial personality disorder]. / Antisosyal kisilik bozuklugu olan erkek bireylerde subjektif uyku kalitesinin saldirganlik ile iliskisi.

OBJECTIVE: The aim of this study was to evaluate subjective sleep quality and to determine its relationship to aggression in male subjects diagnosed with antisocial personality disorder (APD). METHODS: The study included 125 male soldiers with APD that consecutively presented to the outpatient psychiatric unit of GATA Haydarpasa Training Hospital. A control group of 125 normal volunteers with no known medical or psychiatric disorders were selected from among male military personnel. The subjects were evaluated with an assessment battery, which included the Pittsburgh Sleep Quality Index and Aggression Questionnaire, during a semi-structured interview. RESULTS: The main finding was that more of the APD patients suffered from disturbed sleep quality than did the controls. Compared to the matched controls the APD patients had lower subjective sleep quality, longer sleep latency, shorter duration of sleep, less habitual sleep efficiency, more sleep disturbances, more use of sleeping medication, and a higher level of daytime dysfunction. In the APD group, elevated levels of aggression were also significantly correlated with impaired sleep quality. CONCLUSIONS: The present study provides support for a strong link between subjective sleep quality and aggression in APD. Recognition of sleep disturbances in APD patients is also relevant to the management of APD because effective strategies to improve sleep in this patient group might also lead to vast reductions in their aggressive behaviors.

Clinical predictors of therapeutic response to clozapine in a sample of Turkish patients with treatment-resistant schizophrenia.

BACKGROUND: Several lines of evidence suggest that clozapine is more effective than both first- and second-generation antipsychotic drugs in treatment-resistant schizophrenia (TRS). However, clinicians appear to be hesitant to prescribe this drug. It would therefore be extremely valuable if predictors of response to clozapine could be identified. The aim of this study was to evaluate the predictive factors of clinical responses to clozapine in a group of Turkish patients with TRS. METHODS: This was a 16-week uncontrolled open study carried out among 97 TRS patients (80 males and 17 females; DSM-IV diagnosis). All patients fulfilled the criteria for refractory schizophrenia according to the UK guidelines for the National Institute of Clinical Excellence (NICE). After all previous antipsychotic medications had run their course, the patients were started on clozapine according to a standardized titration and dosage schedule. Psychopathology was evaluated before the initiation of clozapine therapy and once every 4 weeks using the Brief Psychiatric Rating Scale (BPRS), the Scale for the Assessment for Positive Symptoms, and the Scale for the Assessment of Negative Symptoms. RESULTS: Of the TRS patients on clozapine, 55.7% achieved a clinical response, defined as at least a 20% decrease in BPRS. We observed a favorable effect of clozapine on both positive and negative symptoms. Logistic regression analysis showed that a good clozapine response was more likely when schizophrenia began at a later age, when negative symptoms were severe, and when patients had an early response at 4 weeks. CONCLUSION: A combination of demographic, baseline clinical, and acute treatment response variables may accurately predict response to clozapine in TRS. Priority should be given to initiating clozapine at the earliest phase of TRS, especially for patients with evident negative symptoms.

Association between dopamine beta hydroxylase gene polymorphism and age at onset in male schizophrenia.

OBJECTIVES: The heterogeneity of schizophrenia mainly results from variations in clinical expressions of the disease, such as age at onset, gender differences in onset of illness, symptoms and response to antipsychotic treatment. Enhanced sensitisation of dopamine pathways in males, having consistently an earlier onset, might be implicated as disease modifiers for schizophrenia in males. METHODS: In this study, we performed a case (n = 87)-control (n = 100) association study between the DBH5'-ins/del and DBH-444g/a polymorphisms of the DBH gene and also compared the level of psychotic symptoms between patients with different DBH genotypes/haplotypes with respect to antipsychotic therapeutic response and gender difference. RESULTS: No significant differences between allele and genotype and haplotype frequencies at either groups (p < 0.05). When the age is considered in patient group, a significant difference was observed between patients with ID genotype and with II genotype (p = 0.018). Patients with ID genotype have been diagnosed as schizophrenics in early ages when compared to II genotype carriers. We also found a significant difference between II and ID genotype (p = 0.007) when the gender had taken into account, showing that the ID genotype carriers had an early onset to schizophrenia. CONCLUSIONS: This association was more significant in male schizophrenia patients than females. Thus, this finding may constitute a novel biological support for the prior finding that onset of schizophrenia varies with gender. The results also showed that critical genetic vulnerability may be associated with the presence or absence of the ID genotype of DBH5'-ins/del.

Clinical characteristics of self-mutilating behavior in Turkish male subjects with antisocial personality disorder: relationship to psychopathy.

AIMS: The aims of this study were to determine the characteristics of self-mutilation (SM) and examine the relationship between SM and psychopathy in male subjects with antisocial personality disorder (APD). METHODS: APD diagnosis was established by the Structured Clinical Interview for DSM-III-R Axis II Disorders. Subjects (N = 116) were assessed using the Psychopathy Checklist-Revised and a semi-structured self-mutilation questionnaire form. RESULTS: In males with APD, the percentages of psychopathy and SM were 48.3% (N =56) and 96.6% (N = 112), respectively. There were positive correlations between severity of psychopathy and severity, number, and frequency of SM. CONCLUSION: Considerably high rates of SM and psychopathy were found in Turkish males with APD. The features of SM were associated with comorbidity of psychopathy. These results showed the importance of exploring the self-injurious behavior and psychopathy when diagnosed with APD.

Plasma orexin A, ghrelin, cholecystokinin, visfatin, leptin and agouti-related protein levels during 6-week olanzapine treatment in first-episode male patients with psychosis.

The objective of the study was to investigate the change of body mass index (BMI), waist circumference, lipid profile, leptin, ghrelin, orexin, visfatin, agouti-related protein, and cholecystokinin levels during 6 weeks of olanzapine treatment in newly diagnosed first-episode drug naive, young adult, nonobese male patients with psychosis. Twenty male participants who were all first-episode drug naive psychotic patients without prominent affective signs and symptoms and 22 healthy male controls of similar age were included. BMI, waist circumference, fasting glucose, and lipid profiles were measured, and Positive and Negative Syndrome Scale and Brief Psychiatric Rating Scale scores were obtained at baseline, during the second and sixth week of treatment, and the aforementioned neuropeptide levels were measured at baseline and during the sixth week of treatment. Treatment was associated with significant increases in BMI, waist circumference, serum triglyceride, and low-density lipoprotein levels. BMI levels increased more than 7% in over 75% of the patients. Leptin increased, and ghrelin and orexin decreased significantly with olanzapine treatment, whereas cholecystokinin, visfatin, and agouti-related protein levels did not change significantly. In conclusion, consistent with previous studies, we found increased BMI, leptin and lipids during olanzapine treatment. Association of neuropeptide level changes with symptom improvement might be mediated by the dopaminergic and serotonergic systems.

Evaluation of general psychopathology, subjective sleep quality, and health-related quality of life in patients with obesity.

OBJECTIVE: Recently, the increasing rate of obesity has been elucidated as a major public health problem. The aim of this study was to examine the psychological distress, subjective sleep quality, and health-related quality of life (HRQOL) in a group of patients diagnosed with obesity. METHODS: A total of 124 obese patients (32 of them Class I obesity (BMI: 30-34.9 kg/m2), 92 Class II obesity (BMI: > or = 35kg/m2)) and 106 healthy control subjects were involved in the study. Subjects were evaluated with self-administered questionnaires including the Symptoms Checklist-90-Revised (SCL-90-R), Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), and Short Form 36 (SF-36). Several clinical and socio-demographic data were also recorded. RESULTS: Class II obesity group had a significantly worse psychological status, quality of life, and sleep quality than control group, Although Class I obesity group did not differ from Class II and control groups according to sleep quality and psychological status, they had worse HRQOL than the control group. BMI scores positively correlated with the majority of subscales of psychological distress (SCL-90-R) and sleep quality (PSQI, ESS) and negatively correlated with all dimensions of HRQOL (SF-36). CONCLUSIONS: Obesity is associated with psychological distress, poor sleep quality, and reduced quality of life. Thus, obesity should be evaluated in a biopsychosocial manner, including management of patients' psychopathology.

A magnetic resonance spectroscopy study of antisocial behaviour disorder, psychopathy and violent crime among military conscripts.

BACKGROUND: Prefrontal and/or temporo-limbic abnormalities associated with antisocial personality disorder (APD), high psychopathy scores and violent behaviours can readily be evaluated by neuroimaging methods. OBJECTIVES: In this study, we compared the brain metabolites in adult male military conscripts with APD, high psychopathy scores and serious violent crimes (n = 15) with age- and educational-level-matched healthy controls (n = 15) by means of magnetic resonance spectroscopy. METHODS: All cases were diagnosed by means of the Diagnostic Statistical Manual-IV APD module of the Structured Clinical Interview for DSM III-R Axis II Disorders (SCID-II) semistructured questionnaire in Turkish. The psychopathy scores were evaluated by means of the Hare Psychopathy Checklist-Revised translated into Turkish (PCL-R). PCL-R is a 20-item, reliable and valid instrument for assessment of psychopathy, both in categorical and dimensional natures. All patients had a total score of 29 (of possible 40) or higher from PCL-R, indicating a high degree of psychopathy. RESULTS: Our results showed no significant differences in ratio of N-acetyl aspartate (NAA), creatine (Cr) and choline-related compounds in the right dorsolateral prefrontal cortex, anterior cingulate cortex (ACC) and amygdala-hippocampus regions of cases compared with controls. ACC NAA/Cr was significantly negatively correlated with both the PCL-R total score and the PCL-R factor I score (interpersonal/affective problems) among the cases. CONCLUSION: As ACC plays an important role in decision-making and emotional information processing, we postulate that the lower NAA/Cr ratio, suggesting impaired neural integrity, may increase the severity of interpersonal/affective problems of the psychopathy factor in male subjects exhibiting APD, high psychopathy overall scores and violent crimes.

A case with euprolactinemic galactorrhea induced by escitalopram.

Endocrine and reproductive side effects of serotonergic antidepressants are uncommon and galactorrhea is only rarely mentioned among SSRI-related side effects. Perhaps through suppression of dopamine neurotransmission releasing prolactin from tonic inhibitor control of dopamine, serotonin-enhancing antidepressants may result in a rise in prolactin levels. However, we here describe a case of euprolactinemic galactorrhea induced by the SSRI escitalopram and discuss potential mechanisms of action.
