Individuals who report psychotic-like experiences are at increased risk of future clinical psychotic disorder. They constitute a unique "high-risk" group for studying the developmental trajectory to schizophrenia and related illnesses. Previous research has used screening instruments to identify this high-risk group, but the validity of these instruments has not yet been established. We administered a screening questionnaire with 7 items designed to assess psychotic-like experiences to 334 adolescents aged 11-13 years. Detailed clinical interviews were subsequently carried out with a sample of these adolescents. We calculated sensitivity and specificity and positive predictive value (PPV) and negative predictive value (NPV) for each screening question for the specific symptom it enquired about and also in relation to any psychotic-like experience. The predictive power varied substantially between items, with the question on auditory hallucinations ("Have you ever heard voices or sounds that no one else can hear?") providing the best predictive power. For interview-verified auditory hallucinations specifically, this question had a PPV of 71.4% and an NPV of 90.4%. When assessed for its predictive power for any psychotic-like experience (including, but not limited to, auditory hallucinations), it provided a PPV of 100% and an NPV of 88.4%. Two further questions-relating to visual hallucinations and paranoid thoughts-also demonstrated good predictive power for psychotic-like experiences. Our results suggest that it may be possible to screen the general adolescent population for psychotic-like experiences with a high degree of accuracy using a short self-report questionnaire.

Background Traumatic events are associated with increased risk of psychotic experiences, but it is unclear whether this association is explained by mental disorders prior to psychotic experience onset. Aims To investigate the associations between traumatic events and subsequent psychotic experience onset after adjusting for post-traumatic stress disorder and other mental disorders. Method We assessed 29 traumatic event types and psychotic experiences from the World Mental Health surveys and examined the associations of traumatic events with subsequent psychotic experience onset with and without adjustments for mental disorders. Results Respondents with any traumatic events had three times the odds of other respondents of subsequently developing psychotic experiences (OR = 3.1, 95% CI 2.7-3.7), with variability in strength of association across traumatic event types. These associations persisted after adjustment for mental disorders. Conclusions Exposure to traumatic events predicts subsequent onset of psychotic experiences even after adjusting for comorbid mental disorders. © The Royal College of Psychiatrists 2017.

Altered social reward functioning is associated with psychosis irrespective of stage and severity. Examining the role of social reward functioning prospectively in relation to psychotic experiences before these become persistent and potentially disabling can aid in elucidating social mechanisms that induce shifts toward more severe psychotic states, without the confounding effects of clinical disorder. In a longitudinal general population sample (N = 566), the experience sampling method (repetitive random sampling of momentary emotions and social context) was used to assess daily life social functioning at baseline. Persistence of subclinical psychotic experiences was based on the Community Assessment of Psychic Experiences assessed three times over 14 months. Analyses examined to what degree i) social context and ii) appreciation thereof differentiated between those who did and did not develop persistent psychotic experiences. Although individuals with persistent psychotic experiences did not differ in overall level of positive effect, the amount of time spent alone or the level of social satisfaction compared to individuals without persistent psychotic experiences, they were more sensitive to the rewarding effects of social company. Alterations in social reward experience may form one of the mechanisms that precede the development of the extended psychosis phenotype over time. © 2013 John Wiley & Sons A/S.

Full Text Available We used Support Vector Machine (SVM to perform multivariate pattern classification based on brain activation during emotional processing in healthy participants with subclinical depressive symptoms. Six-hundred undergraduate students completed the Beck Depression Inventory II (BDI-II. Two groups were subsequently formed: (i subclinical (mild mood disturbance (n = 17 and (ii no mood disturbance (n = 17. Participants also completed a self-report questionnaire on subclinical psychotic symptoms, the Community Assessment of Psychic Experiences Questionnaire (CAPE positive subscale. The functional magnetic resonance imaging (fMRI paradigm entailed passive viewing of negative emotional and neutral scenes. The pattern of brain activity during emotional processing allowed correct group classification with an overall accuracy of 77% (p = 0.002, within a network of regions including the amygdala, insula, anterior cingulate cortex and medial prefrontal cortex. However, further analysis suggested that the classification accuracy could also be explained by subclinical psychotic symptom scores (correlation with SVM weights r = 0.459, p = 0.006. Psychosis proneness may thus be a confounding factor for neuroimaging studies in subclinical depression.

Psychotic experiences and aggression inoutpatients with schizophrenia

Full Text Available Objective: Some authors report that aggressive behaviour in schizophrenia is of heterogeneous sources, for example, aggression may be an impulsive action and even deliberate behaviour designed to intimidate others. Violence and aggressive behaviour may also be associated with psychotic experiences, such as delusions or hallucinations. The aim of this study was to explore the relationship between psychotic experiences and the intensiveness of hostility and aggression in patients with paranoid schizophrenia. Material and method: Seventy outpatients (35 men and 35 women with paranoid schizophrenia were examined. Relevant scales, subscales and indices of the Polish version of Minnesota Multiphasic Personality Inventory (MMPI were used. Results: The analysis of correlation and the factor analysis revealed a number of statistically significant correlations between the scores of the scales assessing psychotic experiences and those assessing the intensiveness of hostility and aggression. Conclusions: The results of this study confirm the presence of a number of relationships between psychotic experiences and felt hostility and aggression. Psychotic symptoms and indices of aggressiveness created five factors: “psychoticism,” “hostility,” “psychopathic aggression,” “poignancy,” “persecutory ideas.” Important for the felt hostility and aggressiveness in patients turned out to be experienced anxiety about their mental health because of the sense of the unreality of what is going on and because of the sense of alienation of their own thoughts. Another important factor turned out to be a sense of being wronged by life, misunderstood by others, and the belief that people have a grudge and try to harm. In contrast, characteristics, attitudes and behaviour which are the opposite of paranoid disorders, i.e. faith in people and optimistic attitude towards them, are an important factor for the inhibition of aggression.

Psychotic experiences are associated with a number of poor clinical outcomes, including multimorbid psychopathology, suicidal behavior, and poor treatment response. We wished to investigate the relationship between psychotic experiences and disability, including the following domains: cognition, mobility, self-care, social interaction, role functioning, and days out of role. We used three nationally representative and racially/ethnically diverse samples of the general US adult population: the National Comorbidity Survey Replication (NCS-R), the National Latino and Asian American Survey (NLAAS), and the National Survey of American Life (NSAL). Multi-variable logistic regression analyses were used to assess the associations between lifetime psychotic experiences (visual and auditory hallucinatory experiences and delusional ideation; WHO Composite International Diagnostic Interview psychosis screen) and 30-day impairments in functioning across disability domains (using the WHO Disability Assessment Schedule II). In all three samples, models were adjusted for socio-demographics and co-occurring psychiatric disorders. In the NCS-R, models were also adjusted for chronic health conditions. Across all three studies, our adjusted models showed that people with disability had anywhere from about 1.5 to over 3 times the odds of reporting lifetime psychotic experiences, depending on the domain. This was true for each disability domain, except self-care in the NLAAS and in the NSAL. Psychotic experiences are markers of risk for disability across a wide range of domains. This may explain the elevated rates of service utilization among individuals who report psychotic experiences and supports the need to assess for and respond to psychotic experiences even in the absence of psychotic disorder.

Most theories of psychotic-like experiences posit the involvement of social-cognitive mechanisms. The current research examined the relations between psychotic-like experiences and two social-cognitive mechanisms, high aberrant salience and low self-concept clarity. In particular, we examined whether aberrant salience, or the incorrect assignment of importance to neutral stimuli, and low self-concept clarity interacted to predict psychotic-like experiences. The current research included three large samples (n = 667, 724, 744) of participants and over-sampled for increased schizotypal personality traits. In all three studies, an interaction between aberrant salience and self-concept clarity was found such that participants with high aberrant salience and low self-concept clarity had the highest levels of psychotic-like experiences. In addition, aberrant salience and self-concept clarity interacted to predict a supplemental measure of delusions in Study 2. In Study 3, in contrast to low self-concept clarity, neuroticism did not interact with aberrant salience to predict psychotic-like experiences, suggesting that the relation between low self-concept clarity and psychosis may not be due to neuroticism. Additionally, aberrant salience and self-concept clarity did not interact to predict to other schizotypal personality disorder criteria, social anhedonia or trait paranoia, which suggests the interaction is specific to psychotic-like experiences. Overall, our results are consistent with several social-cognitive models of psychosis suggesting that aberrant salience and self-concept clarity might be important mechanisms in the occurrence of psychotic-like symptoms.

Bullying Mediates Between Attention-Deficit/Hyperactivity Disorder in Childhood and Psychotic Experiences in Early Adolescence.

2017-09-01

Although a childhood diagnosis of attention-deficit/hyperactivity disorder (ADHD) is known to be linked to psychotic experiences and psychotic disorders in later life, the developmental trajectories that could explain this association are unknown. Using a sample from the prospective population-based Avon Longitudinal Study of Parents and Children (ALSPAC) (N = 8247), we hypothesized that the previously reported association of ADHD combined subtype in childhood and psychotic experiences in early adolescence is mediated by traumatic events and by involvement in bullying. Moreover, we expected this mediation to be specific to ADHD and tested this by comparison with specific phobia. Children with ADHD combined subtype at age 7 were more often involved in bullying at age 10 (OR 3.635, 95% CI 1.973-6.697) and had more psychotic experiences at age 12 (OR 3.362, 95% CI 1.781-6.348). Moreover, children who were involved in bullying had more psychotic experiences (2.005, 95% CI 1.684-2.388). Bullying was a significant mediator between ADHD and psychotic experiences accounting for 41%-50% of the effect. Traumatic events from birth to age 11 were also significantly associated with ADHD combined subtype and psychotic experiences; however, there was no evidence of mediation. Specific phobia was significantly associated with psychotic experiences, but not with bullying. To conclude, bullying is a relevant translating mechanism from ADHD in childhood to psychotic experiences in early adolescence. Interventions that eliminate bullying in children with ADHD could potentially reduce the risk of having psychotic experiences in later life by up to 50%. Clinicians should thus screen for bullying in routine assessments of children with ADHD. © The Author 2016. Published by Oxford University Press on behalf of the Maryland Psychiatric Research Center.

This study aimed to test for overlap in genetic influences between psychotic-like experience traits shown by adolescents in the community, and clinically-recognized psychiatric disorders in adulthood, specifically schizophrenia, bipolar disorder, and major depression. The full spectra of psychotic-like experience domains, both in terms of their severity and type (positive, cognitive, and negative), were assessed using self- and parent-ratings in three European community samples aged 15-19 years (Final N incl. siblings = 6,297-10,098). A mega-genome-wide association study (mega-GWAS) for each psychotic-like experience domain was performed. Single nucleotide polymorphism (SNP)-heritability of each psychotic-like experience domain was estimated using genomic-relatedness-based restricted maximum-likelihood (GREML) and linkage disequilibrium- (LD-) score regression. Genetic overlap between specific psychotic-like experience domains and schizophrenia, bipolar disorder, and major depression was assessed using polygenic risk score (PRS) and LD-score regression. GREML returned SNP-heritability estimates of 3-9% for psychotic-like experience trait domains, with higher estimates for less skewed traits (Anhedonia, Cognitive Disorganization) than for more skewed traits (Paranoia and Hallucinations, Parent-rated Negative Symptoms). Mega-GWAS analysis identified one genome-wide significant association for Anhedonia within IDO2 but which did not replicate in an independent sample. PRS analysis revealed that the schizophrenia PRS significantly predicted all adolescent psychotic-like experience trait domains (Paranoia and Hallucinations only in non-zero scorers). The major depression PRS significantly predicted Anhedonia and Parent-rated Negative Symptoms in adolescence. Psychotic-like experiences during adolescence in the community show additive genetic effects and partly share genetic influences with clinically-recognized psychiatric disorders, specifically schizophrenia and

Exposure to stressful life events during pregnancy has been associated with later schizophrenia in offspring. We explore how prenatal stress and neurodevelopmental abnormalities in childhood associate to increase the risk of later psychotic experiences. Participants from the Mater University Study of Pregnancy (MUSP), an Australian based, pre-birth cohort study were examined for lifetime DSM-IV positive psychotic experiences at 21 years by a semi-structured interview (n = 2227). Structural equation modelling suggested psychotic experiences were best represented with a bifactor model including a general psychosis factor and two group factors. We tested for an association between prenatal stressful life events with the psychotic experiences, and examined for potential moderation and mediation by behaviour problems and cognitive ability in childhood. Prenatal stressful life events predicted psychotic experiences indirectly via behaviour problems at child age five years, and this relationship was not confounded by maternal stressful life events at child age five. We found no statistical evidence for an interaction between prenatal stressful life events and behaviour problems or cognitive ability. The measurable effect of prenatal stressful life events on later psychotic experiences in offspring manifested as behaviour problems by age 5. By identifying early abnormal behavioural development as an intermediary, this finding further confirms the role of prenatal stress to later psychotic disorders. Copyright © 2014 Elsevier Ltd.

We sought to investigate the prevalence and social correlates of psychotic-like experiences in a general population sample of Black and White British subjects. Data were collected from randomly selected community control subjects, recruited as part of the AESOP study, a three-centre population based study of first-episode psychosis. The proportion of subjects reporting one or more psychotic-like experience was 19% (n = 72/372). These were more common in Black Caribbean (OR 2.08) and Black African subjects (OR 4.59), compared with White British. In addition, a number of indicators of childhood and adult disadvantage were associated with psychotic-like experiences. When these variables were simultaneously entered into a regression model, Black African ethnicity, concentrated adult disadvantage, and separation from parents retained a significant effect. The higher prevalence of psychotic-like experiences in the Black Caribbean, but not Black African, group was explained by high levels of social disadvantage over the life course.

Research suggests that altered interregional connectivity in specific networks, such as the default mode network (DMN), is associated with cognitive and psychotic symptoms in schizophrenia. In addition, frontal and limbic connectivity alterations have been associated with trauma, drug use and urban upbringing, though these environmental exposures have never been examined in relation to DMN functional connectivity in psychotic disorder. Resting-state functional MRI scans were obtained from 73 patients with psychotic disorder, 83 non-psychotic siblings of patients with psychotic disorder and 72 healthy controls. Posterior cingulate cortex (PCC) seed-based correlation analysis was used to estimate functional connectivity within the DMN. DMN functional connectivity was examined in relation to group (familial risk), group × environmental exposure (to cannabis, developmental trauma and urbanicity) and symptomatology. There was a significant association between group and PCC connectivity with the inferior parietal lobule (IPL), the precuneus (PCu) and the medial prefrontal cortex (MPFC). Compared to controls, patients and siblings had increased PCC connectivity with the IPL, PCu and MPFC. In the IPL and PCu, the functional connectivity of siblings was intermediate to that of controls and patients. No significant associations were found between DMN connectivity and (subclinical) psychotic/cognitive symptoms. In addition, there were no significant interactions between group and environmental exposures in the model of PCC functional connectivity. Increased functional connectivity in individuals with (increased risk for) psychotic disorder may reflect trait-related network alterations. The within-network "connectivity at rest" intermediate phenotype was not associated with (subclinical) psychotic or cognitive symptoms. The association between familial risk and DMN connectivity was not conditional on environmental exposure.

The aim of the present study was to evaluate the association between sun exposure and psychotic experiences (PEs in a general population sample of Swedish women.MethodsThe study population included participants from The Swedish Women’s Lifestyle and Health cohort study. The 20-item community assessment of psychic experiences (CAPEs was administered between ages 30 and 50 to establish PEs. Sun exposure as measured by (1 sunbathing holidays and (2 history of sunburn was measured between ages 10 and 39. The association between sun exposure and PEs was evaluated by quantile regression models.Results34,297 women were included in the analysis. Women who reported no sunbathing holidays and 2 or more weeks of sunbathing holidays scored higher on the CAPE scale than women exposed to 1 week of sunbathing holidays across the entire distribution, when adjusting for age and education. Similarly, compared with women who reported a history of one sunburn, the women with none or two or more sunburns showed higher scores on the CAPE scale.ConclusionThe results of the present study suggest that, in a population-based cohort of middle aged women, both low and high sun exposure is associated with increased level of positive PEs.

Epidemiological research has shown that hallucinations and delusions, the classic symptoms of psychosis, are far more prevalent in the population than actual psychotic disorder. These symptoms are especially prevalent in childhood and adolescence. Longitudinal research has demonstrated that psychotic symptoms in adolescence increase the risk of psychotic disorder in adulthood. There has been a lack of research, however, on the immediate clinicopathological significance of psychotic symptoms in adolescence.

Recent research conducted in high-income countries suggests psychotic experiences are common in the general population, but evidence from low- and middle-income countries (LMIC) remains limited. Sri Lanka is a LMIC affected by three decades of civil conflict and, in 2004, a devastating tsunami. This study aimed to investigate the prevalence of psychotic experiences in a general population sample in Sri Lanka and associations with conflict- and tsunami-related trauma. This is a first National Mental Health Survey conducted in Sri Lanka. A cross-sectional, multi-stage, cluster sampling design was used to estimate the prevalence of psychotic symptoms. Data on socio-demographic characteristics, conflict- and tsunami-related trauma, and psychotic experiences were collected using culturally validated measures in a sample of 5927 participants. The weighted prevalence of psychotic symptoms was 9.7%. Exposure to one or more conflict-related events (adj. OR 1.79, 95% CI 1.40-2.31, pconflict (adj.

Aetiological mechanisms underlying ethnic density associations with psychosis remain unclear. To assess potential mechanisms underlying the observation that minority ethnic groups experience an increased risk of psychosis when living in neighbourhoods of lower own-group density. Multilevel analysis of nationally representative community-level data (from the Ethnic Minorities Psychiatric Illness Rates in the Community survey), which included the main minority ethnic groups living in England, and a White British group. Structured instruments assessed discrimination, chronic strains and social support. The Psychosis Screening Questionnaire ascertained psychotic experiences. For every ten percentage point reduction in own-group density, the relative odds of reporting psychotic experiences increased 1.07 times (95% CI 1.01-1.14, P = 0.03 (trend)) for the total minority ethnic sample. In general, people living in areas of lower own-group density experienced greater social adversity that was in turn associated with reporting psychotic experiences. People resident in neighbourhoods of higher own-group density experience 'buffering' effects from the social risk factors for psychosis.

War experiences and psychotic symptoms among former child soldiers in Northern Uganda: the mediating role of post-war hardships – the WAYS Study

Psychotic symptoms have been associated with post-traumatic stress disorder and war experiences. However, the relationships between types of war experiences, the onset and course of psychotic symptoms, and post-war hardships in child soldiers have not been investigated. This study assessed whether various types of war experiences contribute to psychotic symptoms differently and whether post-war hardships mediated the relationship between war experiences and later psychotic symptoms. In an ongoing longitudinal cohort study (the War-Affected Youths Survey), 539 (61% male) former child soldiers were assessed for psychotic symptoms, post-war hardships, and previous war experiences. Regression analyses were used to assess the contribution of different types of war experiences on psychotic symptoms and the mediating role of post-war hardships in the relations between previous war experiences and psychotic symptoms. The findings yielded ‘witnessing violence’, ‘deaths and bereavement’, ‘involvement in hostilities’, and ‘sexual abuse’ as types of war experiences that significantly and independently predict psychotic symptoms. Exposure to war experiences was related to psychotic symptoms through post-war hardships (β = .18, 95% confidence interval = [0.10, 0.25]) accounting for 50% of the variance in their relationship. The direct relation between previous war experiences and psychotic symptoms attenuated but remained significant (β = .18, 95% confidence interval = [0.12, 0.26]). Types of war experiences should be considered when evaluating risks for psychotic symptoms in the course of providing emergency humanitarian services in post-conflict settings. Interventions should consider post-war hardships as key determinants of psychotic symptoms among war-affected youths. PMID:24718435

Psychotic Experiences and Overhasty Inferences Are Related to Maladaptive Learning.

Directory of Open Access Journals (Sweden)

Heiner Stuke

2017-01-01

Full Text Available Theoretical accounts suggest that an alteration in the brain's learning mechanisms might lead to overhasty inferences, resulting in psychotic symptoms. Here, we sought to elucidate the suggested link between maladaptive learning and psychosis. Ninety-eight healthy individuals with varying degrees of delusional ideation and hallucinatory experiences performed a probabilistic reasoning task that allowed us to quantify overhasty inferences. Replicating previous results, we found a relationship between psychotic experiences and overhasty inferences during probabilistic reasoning. Computational modelling revealed that the behavioral data was best explained by a novel computational learning model that formalizes the adaptiveness of learning by a non-linear distortion of prediction error processing, where an increased non-linearity implies a growing resilience against learning from surprising and thus unreliable information (large prediction errors. Most importantly, a decreased adaptiveness of learning predicted delusional ideation and hallucinatory experiences. Our current findings provide a formal description of the computational mechanisms underlying overhasty inferences, thereby empirically substantiating theories that link psychosis to maladaptive learning.

A systematic review of genome-wide research on psychotic experiences and negative symptom traits: New revelations and implications for psychiatry.

Science.gov (United States)

Ronald, Angelica; Pain, Oliver

2018-05-08

We present a systematic review of genome-wide research on psychotic experience and negative symptom traits (PENS) in the community. We integrate these new findings, most of which have emerged over the last four years, with more established behaviour genetic and epidemiological research. The review includes the first genome-wide association studies of PENS, including a recent meta-analysis, and the first SNP heritability estimates. Sample sizes of < 10,000 participants mean that no genome-wide significant variants have yet been replicated. Importantly, however, in the most recent and well-powered studies, polygenic risk score prediction and linkage disequilibrium (LD) score regression analyses show that all types of PENS share genetic influences with diagnosed schizophrenia and that negative symptom traits also share genetic influences with major depression. These genetic findings corroborate other evidence in supporting a link between PENS in the community and psychiatric conditions. Beyond the systematic review, we highlight recent work on gene-environment correlation, which appears to be a relevant process for psychotic experiences. Genes that influence risk factors such as tobacco use and stressful life events are likely to be harbouring 'hits' that also influence PENS. We argue for the acceptance of PENS within the mainstream, as heritable traits in the same vein as other subclinical psychopathology and personality styles such as neuroticism. While acknowledging some mixed findings, new evidence shows genetic overlap between PENS and psychiatric conditions. In sum, normal variations in adolescent and adult thinking styles, such as feeling paranoid, are heritable and show genetic associations with schizophrenia and major depression.

Participants were from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally-representative cohort of 2232 British twins who were interviewed about adolescent psychotic experiences at age 18. Urbanicity, neighborhood characteristics, and personal victimization by violent crime were measured during childhood and adolescence via geocoded census data, surveys of over 5000 immediate neighbors of the E-Risk participants, and interviews with participants themselves. Adolescents raised in urban vs rural neighborhoods were significantly more likely to have psychotic experiences (OR = 1.67, 95% CI = 1.21-2.30, P = .002). This association remained significant after considering potential confounders including family socioeconomic status, family psychiatric history, and adolescent substance problems (OR = 1.43, 95% CI = 1.01-2.03, P = .042), but became nonsignificant after considering adverse social conditions in urban neighborhoods such as low social cohesion and high neighborhood disorder (OR = 1.35, 95% CI = 0.94-1.92, P = .102). The combined association of adverse neighborhood social conditions and personal crime victimization with adolescent psychotic experiences (adjusted OR = 4.86, 95% CI = 3.28-7.20, P < .001) was substantially greater than for either exposure alone, highlighting a potential interaction between neighborhood conditions and crime victimization (interaction contrast ratio = 1.81, 95% CI = -0.03 to 3.65) that was significant at the P = .054 level. Cumulative effects of adverse neighborhood social conditions and personal victimization by violent crime during upbringing partly explain why adolescents in urban settings are more likely to report psychotic experiences. Early intervention efforts for psychosis could be targeted towards victimized youth living in urban and socially

Criminal victimization has been associated with elevated risk for psychotic symptoms in the United Kingdom, but has not been studied in low- and middle-income countries (LMICs). Understanding whether crime exposure may play a role in the social etiology of psychosis could help guide prevention and intervention efforts. We tested the hypothesis that criminal victimization would be associated with elevated odds of psychotic experiences in 35 LMICs (N = 146 999) using cross-sectional data from the World Health Organization World Health Survey. Multivariable logistic regression analyses were used to test for associations between criminal victimization and psychotic experiences. Victimization was associated with greater odds of psychotic experiences, OR (95% CI) = 1.72 (1.50-1.98), and was significantly more strongly associated with psychotic experiences in non-urban, OR (95% CI) = 1.93 (1.60-2.33), compared to urban settings, OR (95% CI) = 1.48 (1.21-1.81). The association between victimization and psychosis did not change across countries with varying aggregated levels of criminal victimization. In the largest ever study of victimization and psychosis, the association between criminal victimization and psychosis appears to generalize across a range of LMICs and, therefore, across nations with a broad range of crime rates, degree of urban development, average per capita income, and racial/ethnic make-up. © 2018 John Wiley & Sons A/S.

The relationship between young adulthood, women and psychosis was the focus for this systematic review. Age and gender are factors that can influence responses to illness. Research indicates that there are differences in how young men and women are affected biologically and psychosocially, including the presentation of a constellation of symptoms, response to anti-psychotic medications and how they assess their life circumstances. Yet in literature that examines experiences of young people with psychosis, the specific needs of young women are usually not presented separately. To better understand and address young adult women's healthcare and social service needs, a synthesis of evidence addressing the relationship between young adulthood, women and psychosis is needed. The aim of this systematic review was to synthesize the best available evidence on the experiences of young adult women (aged 18-35 years) living with a psychotic illness in the community. Specifically, the review question was:What are the experiences of young adult women living with a psychotic illness? Participants were young women between 18 and 35 years of age who were living with a psychotic illness in the community. The phenomenon of interest was the experiences of living with a psychotic illness of women aged 18-35 years in the community. Experiences were defined broadly as and inclusive of perceptions and experiences with health and social systems. The context for this review was the community setting. The current review included studies that focused on qualitative data including, but not limited to, designs such as phenomenology, grounded theory, ethnography, action research, feminist research and the qualitative component of mixed methods studies. A three-step search strategy was used to locate both published and unpublished studies. The search was limited to studies published from 1995 to the search date of May 13, 2015. Two reviewers independently appraised the nine included studies

Are genetic risk factors for psychosis also associated with dimension-specific psychotic experiences in adolescence?

Full Text Available Psychosis has been hypothesised to be a continuously distributed quantitative phenotype and disorders such as schizophrenia and bipolar disorder represent its extreme manifestations. Evidence suggests that common genetic variants play an important role in liability to both schizophrenia and bipolar disorder. Here we tested the hypothesis that these common variants would also influence psychotic experiences measured dimensionally in adolescents in the general population. Our aim was to test whether schizophrenia and bipolar disorder polygenic risk scores (PRS, as well as specific single nucleotide polymorphisms (SNPs previously identified as risk variants for schizophrenia, were associated with adolescent dimension-specific psychotic experiences. Self-reported Paranoia, Hallucinations, Cognitive Disorganisation, Grandiosity, Anhedonia, and Parent-rated Negative Symptoms, as measured by the Specific Psychotic Experiences Questionnaire (SPEQ, were assessed in a community sample of 2,152 16-year-olds. Polygenic risk scores were calculated using estimates of the log of odds ratios from the Psychiatric Genomics Consortium GWAS stage-1 mega-analysis of schizophrenia and bipolar disorder. The polygenic risk analyses yielded no significant associations between schizophrenia and bipolar disorder PRS and the SPEQ measures. The analyses on the 28 individual SNPs previously associated with schizophrenia found that two SNPs in TCF4 returned a significant association with the SPEQ Paranoia dimension, rs17512836 (p-value = 2.57×10⁻⁴ and rs9960767 (p-value = 6.23×10⁻⁴. Replication in an independent sample of 16-year-olds (N = 3,427 assessed using the Psychotic-Like Symptoms Questionnaire (PLIKS-Q, a composite measure of multiple positive psychotic experiences, failed to yield significant results. Future research with PRS derived from larger samples, as well as larger adolescent validation samples, would improve the predictive power to test

Studies suggest associations between childhood autistic traits and adolescent psychotic experiences. However, recent research suggests that a general neuropsychiatric problems factor predicts adverse outcomes better than specific diagnostic entities. To examine if the alleged association between autistic traits and psychotic experiences could rather be explained by a general neuropsychiatric problems factor comprising symptoms of ADHD, tic disorder, developmental coordination disorder, and learning disorder, we conducted a prospective cohort study based on the Child and Adolescent Twin Study in Sweden. In addition, we examined the genetic and environmental influences on the associations. A total of 9,282 twins with data on childhood autistic traits and other neuropsychiatric problems, and follow-up data on psychotic experiences at ages 15 and/or 18 years were included. First, psychotic experiences were regressed on autistic traits and second, the general neuropsychiatric problems factor was added to the model. Auditory hallucinations were analyzed separately from the other psychotic experiences. Finally, twin analyses were employed to disentangle genetic from environmental influences in the observed associations. Replicating prior research, significant associations were found between autistic traits in childhood and auditory hallucinations at ages 15 and 18. However, after controlling for the general neuropsychiatric problems factor, the associations between autistic traits and auditory hallucinations disappeared, whereas the association between the general neuropsychiatric problems factor and auditory hallucinations persisted after controlling for autistic traits. Twin analyses revealed that the association between the general neuropsychiatric problems factor and auditory hallucinations was driven by shared genetic influences. © 2015 Wiley Periodicals, Inc. © 2015 Wiley Periodicals, Inc.

Stress has a central role in most theories of psychosis etiology, but the relation between stress and psychosis has rarely been examined in large population-level data sets, particularly in low- and middle-income countries. We used data from 39 countries in the World Health Survey (n = 176 934) to test the hypothesis that stress sensitivity would be associated with psychotic experiences, using logistic regression analyses. Respondents in low-income countries reported higher stress sensitivity (P countries. Greater stress sensitivity was associated with increased odds for psychotic experiences, even when adjusted for co-occurring anxiety and depressive symptoms: adjusted odds ratio (95% CI) = 1.17 (1.15-1.19) per unit increase in stress sensitivity (range 2-10). This association was consistent and significant across nearly every country studied, and translated into a difference in psychotic experience prevalence ranging from 6.4% among those with the lowest levels of stress sensitivity up to 22.2% among those with the highest levels. These findings highlight the generalizability of the association between psychosis and stress sensitivity in the largest and most globally representative community-level sample to date, and support the targeting of stress sensitivity as a potential component of individual- and population-level interventions for psychosis. © The Author 2016.

Full Text Available Abstract Background In primary care, GPs usually provide care for patients with chronic diseases according to professional guidelines. However, such guidelines are not available in the Netherlands for patients with recurring psychoses. It seems that the specific difficulties that GPs experience in providing care for these patients hinder the development and implementation of such guidelines. This study aims to explore the chances and problems GPs meet when providing care for patients susceptible for recurring psychoses, including schizophrenia and related disorders, bipolar disorder, and psychotic depression. Methods A qualitative study of focus group discussions with practising GPs in both town and rural areas. Transcripts from three focus groups with 19 GPs were analysed with the computer program 'Kwalitan'. Theoretical saturation was achieved after these three groups. Results Analysis showed that eight categories of factors influenced the GPs' care for psychotic patients: patient presentation (acute vs. chronic phase, emotional impact, expertise, professional attitude, patient related factors, patient's family, practice organization, and collaboration with psychiatric specialists. Conclusion Current primary care for psychotic patients depends very much on personal characteristics of the GP and the quality of local collaboration with the Mental Health Service. A quantitative study among GPs using a questionnaire based on the eight categories mentioned above would determine the extent of the problems and limitations experienced with this type of care. From the results of this quantitative study, new realistic guidelines could be developed to improve the quality of care for psychotic patients.

Social anhedonia (SA) and withdrawal are clinically relevant phenomena in schizophrenia. To examine the nature of the overlap between SA, withdrawal and positive symptoms, we investigated whether the co-occurrence of these phenotypes is more prominent in siblings of patients with a psychotic disorder compared to healthy controls, and if this association is independent of the amount of distress caused by psychotic experiences (PEs). Data were derived from 646 unaffected siblings and 326 healthy controls who were included in the Dutch Genetic Risk and Outcome in Psychosis (GROUP) study. PEs were assessed with the Community Assessment of Psychic Experiences and the Structured Interview for Schizotypy-Revised was used to examine social anhedonia and withdrawal. Our results show relatively small but significant cross-sectional associations between SA, withdrawal and PEs in unaffected siblings and none in the control group, irrespective of the level of distress caused by PEs. The findings of the present study suggest that the overlap between SA, withdrawal and psychotic symptoms often reported in schizophrenia patients, may at least partly reflect a shared genetic vulnerability, instead of merely being either a state marker of - or reaction to - acute psychotic symptoms.

This thesis assesses psychotic-like symptomatology and reward responsivity in chronic users of two illicit drugs, cannabis and ketamine. As use of these drugs is steadily increasing, with cannabis being the most widely used drug worldwide (following alcohol, caffeine and tobacco) and the recent proliferation of ketamine misuse in parts of Asia, Europe and the United States, it is important to examine the effects of their habitual use. While research has linked cannabis use to sub-clinical psy...

This study investigated how severely depressed individuals experienced the relationship between psychotic symptoms and suicidal ideation and behavior. Semi-structured qualitative interviews were conducted with a purposive sample of nine inpatients from a psychiatric university hospital between September 2012 and May 2013 fulfilling diagnostic criteria for a psychotic depressive episode as part of a unipolar or bipolar disorder. Analysis was conducted using systematic text condensation. Participants experienced (1) being directed to perform impulsive potentially fatal actions, (2) feeling hounded to death, (3) becoming trapped in an inescapable darkness, and (4) being left bereft of mental control. They described how impulsivity directed by delusions and hallucinations resulted in unpredictable actions with only moments from decision to conduct. Suicide was seen as an escape not only from life problems but also from psychotic experiences and intense anxiety. Participants reported being in a chaotic state, unable to think rationally or anticipate the consequences of their actions. Their ability to identify and communicate psychotic symptoms and suicidal ideation and behavior was compromised, leaving them to struggle alone with these terrifying experiences. Suicide risk assessments based on verbal reports from individuals with psychotic depression may not always be valid due to potential impulsivity and underreporting of suicidal ideation. It may be important for clinicians to explore the delusional content of such patients' experiences to assess the possibility of suicide as a result of shame, guilt, remorse, or altruistic intentions to save others from harm.

An evidence base for the treatment of mania and bipolar depression with psychotic symptoms is lacking. Nevertheless, clinicians may have a preference for treating episodes of bipolar disorder with or without psychotic symptoms in different ways, which is likely to reflect notions of differential efficacy of treatments between these subtypes. This study aimed to investigate whether the psychopharmacological treatment of psychotic and non-psychotic episodes of mania and bipolar depression, respectively, differs in clinical practice. We conducted a register-based study assessing the psychopharmacological treatment of all individuals receiving their first diagnosis of mania or bipolar depression between 2010 and 2012. The psychopharmacological treatment within 3 months following the time of diagnosis was considered. Potential differences in psychopharmacological treatment between the psychotic and non-psychotic subtypes of mania and bipolar depression, respectively, were investigated by means of Pearson's χ 2 test and logistic regression adjusted for sex and age at diagnosis of bipolar disorder. A total of 827 patients were included in the analyses. The adjusted odds ratio (aOR) for treatment with an antipsychotic was 1.71 (95% confidence interval [CI]: 1.18-2.48, Pbipolar depression. The aOR for treatment with the combination of an antipsychotic and an anticonvulsant was 1.60 (95% CI: 1.06-2.43, Pbipolar psychotic depression. It would be of interest to conduct studies evaluating whether antipsychotics represent the superior pharmacological treatment for psychotic mania and psychotic bipolar depression. © 2017 John Wiley & Sons A/S.

Full Text Available Although depressive symptoms in first episode psychosis have been associated with cannabis abuse, their influence on the long-term functional course of FEP patients who abuse cannabis is unknown. The aims of the study were to examine the influence of subclinical depressive symptoms on the long-term outcome in first episode-psychosis patients who were cannabis users and to assess the influence of these subclinical depressive symptoms on the ability to quit cannabis use.64 FEP patients who were cannabis users at baseline were followed-up for 5 years. Two groups were defined: (a patients with subclinical depressive symptoms at least once during follow-up (DPG, and (b patients without subclinical depressive symptoms during follow-up (NDPG. Psychotic symptoms were measured using the Positive and Negative Syndrome Scale (PANSS, depressive symptoms using the Hamilton Depression Rating Scale (HDRS-17, and psychosocial functioning was assessed using the Global Assessment of Functioning (GAF. A linear mixed-effects model was used to analyze the combined influence of cannabis use and subclinical depressive symptomatology on the clinical outcome.Subclinical depressive symptoms were associated with continued abuse of cannabis during follow-up (β= 4.45; 95% confidence interval [CI]: 1.78 to 11.17; P = .001 and with worse functioning (β = -5.50; 95% CI: -9.02 to -0.33; P = .009.Subclinical depressive symptoms and continued cannabis abuse during follow-up could be predictors of negative outcomes in FEP patients.

Impact of Adverse Childhood Experiences on Psychotic-Like Symptoms and Stress Reactivity in Daily Life in Nonclinical Young Adults.

Full Text Available There is increasing interest in elucidating the association of different childhood adversities with psychosis-spectrum symptoms as well as the mechanistic processes involved. This study used experience sampling methodology to examine (i associations of a range of childhood adversities with psychosis symptom domains in daily life; (ii whether associations of abuse and neglect with symptoms are consistent across self-report and interview methods of trauma assessment; and (iii the role of different adversities in moderating affective, psychotic-like, and paranoid reactivity to situational and social stressors.A total of 206 nonclinical young adults were administered self-report and interview measures to assess childhood abuse, neglect, bullying, losses, and general traumatic events. Participants received personal digital assistants that signaled them randomly eight times daily for one week to complete questionnaires about current experiences, including symptoms, affect, and stress.Self-reported and interview-based abuse and neglect were associated with psychotic-like and paranoid symptoms, whereas only self-reported neglect was associated with negative-like symptoms. Bullying was associated with psychotic-like symptoms. Losses and general traumatic events were not directly associated with any of the symptom domains. All the childhood adversities were associated with stress reactivity in daily life. Interpersonal adversities (abuse, neglect, bullying, and losses moderated psychotic-like and/or paranoid reactivity to situational and social stressors, whereas general traumatic events moderated psychotic-like reactivity to situational stress. Also, different interpersonal adversities exacerbated psychotic-like and/or paranoid symptoms in response to distinct social stressors.The present study provides a unique examination of how childhood adversities impact the expression of spectrum symptoms in the real world and lends support to the notion that

In Europe, it is widely established that immigration increases risk for psychotic disorder. However, research has yet to confirm this association in the United States, where immigrants paradoxically report better health status than their native-born counterparts. Further, few studies have examined this topic with respect to sub-threshold psychotic experiences, which are more common than psychotic disorders in the general population. This study analyzes the (1) National Comorbidity Survey-Replication, (2) the National Latino and Asian American Survey, and (3) the National Survey of American Life, in order to determine whether generation status had any impact on risk for lifetime and 12-month PE, and whether these associations vary across racial/ethnic groups, adjusting for demographic variables and socioeconomic status. We found an absence of an immigration effect on PE across various ethnic groups and across various geographic areas, and found that immigration is actually protective among Latinos, supporting the idea that the epidemiological paradox extends to the psychosis phenotype.

Alterations in Theory-of-Mind (ToM) are associated with psychotic disorder. In addition, studies in children have documented that alterations in ToM are associated with Psychotic Experiences (PE). Our aim was to examine associations between an exaggerated type of ToM (HyperToM) and PE in children. Children with this type of alteration in ToM infer mental states when none are obviously suggested, and predict behaviour on the basis of these erroneous beliefs. Individuals with HyperToM do not appear to have a conceptual deficit (i.e. lack of representational abilities), but rather they apply their theory of the minds of others in an incorrect or biased way. Hypotheses were tested in two studies with two independent samples: (i) a general population sample of 1630 Danish children aged 11-12 years, (ii) a population-based sample of 259 Dutch children aged 12-13 years, pertaining to a case-control sampling frame of children with auditory verbal hallucinations. Multinomial regression analyses were carried out to investigate the associations between PE and ToM and HyperToM respectively. Analyses were adjusted for gender and proxy measures of general intelligence. Low ToM score was significantly associated with PE in sample I (OR = 1.6 95%CI 1.1-2.3 χ2(4) = 12.42 p = 0.010), but not in sample II (OR = 0.9 95%CI 0.5-1.8 χ2(3) = 7.13 p = 0.816). HyperToM was significantly associated with PE both in sample I (OR = 1.8, 95%CI 1.2-2.7 χ2(3) = 10.11 p = 0.006) and II (OR = 4.6, 95%CI 1.3-16.2 χ2(2) = 7.56 p = 0.018). HyperToM was associated particularly with paranoid delusions in both sample I (OR = 2.0, 95%CI: 1.1-3.7% χ2(4) = 9.93 p = 0.021) and II (OR = 6.2 95%CI: 1.7-23.6% χ2(4) = 9.90 p = 0.044). Specific alterations in ToM may be associated with specific types of psychotic experiences. HyperToM may index risk for developing psychosis and paranoid delusions in particular.

Aims. This study aimed to establish the contribution of hallucination proneness, anxiety, suggestibility, and fantasy proneness to psychotic-like experiences (PLEs) reported during brief sensory deprivation. Method. Twenty-four high and 22 low hallucination-prone participants reported on PLEs occurring during brief sensory deprivation and at baseline. State/trait anxiety, suggestibility, and fantasy proneness were also measured. Results. Both groups experienced a significant increase in PLEs in sensory deprivation. The high hallucination prone group reported more PLEs both at baseline and in sensory deprivation. They also scored significantly higher on measures of state/trait anxiety, suggestibility, and fantasy proneness, though these did not explain the effects of group or condition. Regression analysis found hallucination proneness to be the best predictor of the increase in PLEs, with state anxiety also being a significant predictor. Fantasy proneness and suggestibility were not significant predictors. Conclusion. This study suggests the increase in PLEs reported during sensory deprivation reflects a genuine aberration in perceptual experience, as opposed to increased tendency to make false reports due to suggestibility of fantasy proneness. The study provides further support for the use of sensory deprivation as a safe and effective nonpharmacological model of psychosis. PMID:25811027

State/trait anxiety, suggestibility, and fantasy proneness were also measured. Results. Both groups experienced a significant increase in PLEs in sensory deprivation. The high hallucination prone group reported more PLEs both at baseline and in sensory deprivation. They also scored significantly higher on measures of state/trait anxiety, suggestibility, and fantasy proneness, though these did not explain the effects of group or condition. Regression analysis found hallucination proneness to be the best predictor of the increase in PLEs, with state anxiety also being a significant predictor. Fantasy proneness and suggestibility were not significant predictors. Conclusion. This study suggests the increase in PLEs reported during sensory deprivation reflects a genuine aberration in perceptual experience, as opposed to increased tendency to make false reports due to suggestibility of fantasy proneness. The study provides further support for the use of sensory deprivation as a safe and effective nonpharmacological model of psychosis.

The objective of this study was to examine the relationship between perceived discrimination and psychotic experiences (PE) using validated measures of discrimination and a racially/ethnically diverse population-level sample. Data were drawn from two population-level surveys (The National Latino and Asian American Survey and The National Survey of American Life), which were analyzed together using survey weights and stratification variables. The analytic sample (N=8990) consisted of Latino, Asian, African-American, and Afro-Caribbean adults living in the United States. Separate unadjusted and adjusted multivariable logistic regression models were used, first to examine the crude bivariate relationship between perceived discrimination and PE, and second to examine the relationship adjusting for demographic variables. Adjusted logistic regression models were also used to examine the relationships between perceived discrimination and specific sub-types of PE (auditory and visual hallucinatory experiences, and delusional ideation). When compared to individuals who did not report any discrimination, those who reported the highest levels of discrimination were significantly more likely to report both 12-month PE (Adjusted OR=4.590, pPerceived discrimination is associated with the increased probability of reporting psychotic experiences in a linear Fashion in the US general population.

The Community Assessment of Psychic Experiences (CAPE) is an effective instrument for detection of the presence of psychotic symptoms and associated distress in the general population. However, little research has studied distress associated with positive psychotic-like experiences (PLEs). Our aim is to study PLE-related distress using the CAPE. In this study we analysed factors associated with differences in PLE-related distress in a sample of 200 non-clinical participants recruited by snowball sampling. Presence of PLEs and related psychological distress was measured using the CAPE questionnaire. The influence of age, gender, educational level and drug use was studied. In univariate analysis we found that gender and CAPE positive, depressive and negative scores, were associated with CAPE positive distress. Using multiple linear regression, we found that only the effect of gender, and the interaction between frequency of depression and gender, remained statistically significant. In our sample interaction between gender and depressive symptoms is a determining factor in distress associated with positive PLEs. The results of this study may be useful for the implementation of prevention programs. Copyright © 2017 Elsevier B.V. All rights reserved.

Psychotic experiences and hyper-theory-of-mind in preadolescence

2016-01-01

BACKGROUND: Knowledge on the risk mechanisms of psychotic experiences (PE) is still limited. The aim of this population-based study was to explore developmental markers of PE with a particular focus on the specificity of hyper-theory-of-mind (HyperToM) as correlate of PE as opposed to correlate...... psychiatric liability; parental mental illness during early child development; change in family composition; low family income; regulatory problems in infancy; onset of puberty; bullying; concurrent mental disorder; and HyperToM. When estimating the adjusted effects, only low family income, concurrent mental...... disorder, bullying and HyperToM remained significantly associated with PE. Further analyses of the specificity of these correlates with regard to outcome revealed that HyperToM was the only variable specifically associated with PE without concurrent mental disorder. Finally, HyperToM did not share any...

Cannabis users are more likely to have psychotic experiences (PEs). The degree to which these associations are driven by genetic or environmental influences in adolescence is unknown. This study estimated the genetic and environmental contributions to the relationship between cannabis use and PEs. Specific PEs were measured in a community-based twin sample (4830 16-year-old pairs) using self-reports and parent-reports. Adolescents reported on ever using cannabis. Multivariate liability threshold structural equation model-fitting was conducted. Cannabis use was significantly correlated with PEs. Modest heritability (37%), common environmental influences (55%) and unique environment (8%) were found for cannabis use. For PEs, modest heritability (27–54%), unique environmental influences (E=12–50%) and little common environmental influences (11–20%), with the exception of parent-rated Negative Symptoms (42%), were reported. Environmental influences explained all of the covariation between cannabis use and paranoia, cognitive disorganization and parent-rated negative symptoms (bivariate common environment=69–100%, bivariate unique environment=28–31%), whilst the relationship between cannabis use and hallucinations indicated familial influences. Cannabis use explains 2–5% of variance in positive, cognitive, and negative PEs. Cannabis use and psychotic experience co-occur due to environmental factors. Focus on specific environments may reveal why adolescent cannabis use and psychotic experiences tend to ‘travel together’. PMID:25912376

Patients with narcolepsy often experience pervasive hypnagogic hallucinations, sometimes even leading to confusion with schizophrenia. We aimed to provide a detailed qualitative description of hypnagogic hallucinations and other "psychotic" symptoms in patients with narcolepsy and contrast these with schizophrenia patients and healthy controls. We also compared the prevalence of formal psychotic disorders between narcolepsy patients and controls. We used SCAN 2.1 interviews to compare psychotic symptoms between 60 patients with narcolepsy, 102 with schizophrenia and 120 matched population controls. In addition, qualitative data was collected to enable a detailed description of hypnagogic hallucinations in narcolepsy. There were clear differences in the pattern of hallucinatory experiences in narcolepsy vs. schizophrenia patients. Narcoleptics reported multisensory "holistic" hallucinations rather than the predominantly verbal-auditory sensory mode of schizophrenia patients. Psychotic symptoms such as delusions were not more frequent in narcolepsy compared to population controls. In addition, the prevalence of formal psychotic disorders was not increased in patients with narcolepsy. Almost half of narcoleptics reported moderate interference with functioning due to hypnagogic hallucinations, mostly due to related anxiety. Hypnagogic hallucinations in narcolepsy can be differentiated on a phenomenological basis from hallucinations in schizophrenia which is useful in differential diagnostic dilemmas.

Favrod Jerome

2012-09-01

Full Text Available Abstract Background Most scales that assess the presence and severity of psychotic symptoms often measure a broad range of experiences and behaviours, something that restricts the detailed measurement of specific symptoms such as delusions or hallucinations. The Psychotic Symptom Rating Scales (PSYRATS is a clinical assessment tool that focuses on the detailed measurement of these core symptoms. The goal of this study was to examine the psychometric properties of the French version of the PSYRATS. Methods A sample of 103 outpatients suffering from schizophrenia or schizoaffective disorders and presenting persistent psychotic symptoms over the previous three months was assessed using the PSYRATS. Seventy-five sample participants were also assessed with the Positive And Negative Syndrome Scale (PANSS. Results ICCs were superior to .90 for all items of the PSYRATS. Factor analysis replicated the factorial structure of the original version of the delusions scale. Similar to previous replications, the factor structure of the hallucinations scale was partially replicated. Convergent validity indicated that some specific PSYRATS items do not correlate with the PANSS delusions or hallucinations. The distress items of the PSYRATS are negatively correlated with the grandiosity scale of the PANSS. Conclusions The results of this study are limited by the relatively small sample size as well as the selection of participants with persistent symptoms. The French version of the PSYRATS partially replicates previously published results. Differences in factor structure of the hallucinations scale might be explained by greater variability of its elements. The future development of the scale should take into account the presence of grandiosity in order to better capture details of the psychotic experience.

Psychotic-like experiences in the general population: characterizing a high-risk group for psychosis.

LENUS (Irish Health Repository)

Kelleher, I

2011-01-01

Recent research shows that psychotic symptoms, or psychotic-like experiences (PLEs), are reported not only by psychosis patients but also by healthy members of the general population. Healthy individuals who report these symptoms are considered to represent a non-clinical psychosis phenotype, and have been demonstrated to be at increased risk of schizophrenia-spectrum disorder. Converging research now shows that this non-clinical psychosis phenotype is familial, heritable and covaries with familial schizophrenia-spectrum disorder. A review of the research also shows that the non-clinical phenotype is associated extensively with schizophrenia-related risk factors, including social, environmental, substance use, obstetric, developmental, anatomical, motor, cognitive, linguistic, intellectual and psychopathological risk factors. The criterion and construct validity of the non-clinical psychosis phenotype with schizophrenia demonstrates that it is a valid population in which to study the aetiology of psychosis. Furthermore, it suggests shared genetic variation between the clinical and non-clinical phenotypes. Much remains to be learned about psychosis by broadening the scope of research to include the non-clinical psychosis phenotype.

Genetic moderation of the effects of cannabis: catechol-O-methyltransferase (COMT) affects the impact of Δ9-tetrahydrocannabinol (THC) on working memory performance but not on the occurrence of psychotic experiences.

Cannabis use can induce cognitive impairments and psychotic experiences. A functional polymorphism in the catechol-O-methyltransferase (COMT) gene (Val(158)Met) appears to influence the immediate cognitive and psychotic effects of cannabis, or ∆(9)-tetrahydrocannabinol (THC), its primary psychoactive ingredient. This study investigated the moderation of the impact of experimentally administered THC by COMT. Cognitive performance and psychotic experiences were studied in participants without a psychiatric diagnosis, using a between-subjects design (THC vs. placebo). The effect of COMT Val(158)Met genotype on the cognitive and psychotic effects of THC, administered intravenously in a double-blind, placebo-controlled manner to 78 participants who were vulnerable to paranoia, was examined. The results showed interactive effects of genotype and drug group (THC or placebo) on working memory, assayed using the Digit Span Backwards task. Specifically, THC impaired performance in COMT Val/Val, but not Met, carriers. In contrast, the effect of THC on psychotic experiences, measured using the Community Assessment of Psychic Experiences (CAPE) positive dimension, was unaffected by COMT genotype. This study is the largest to date examining the impact of COMT genotype on response to experimentally administered THC, and the first using a purely non-clinical cohort. The data suggest that COMT genotype moderates the cognitive, but not the psychotic, effects of acutely administered THC. © The Author(s) 2015.

The association between childhood maltreatment (ChM) and psychotic disorders is well established. However, there is an ongoing debate about which factors account for this relationship. One explanation is that the relationship between ChM and psychosis is mediated by adult attachment style. Therefore, in this study, we aimed to investigate whether adult attachment style mediates the relationship between ChM and positive and negative symptomatology. We investigated the relation between ChM and psychotic symptoms, taking into account levels of (insecure) attachment, in 131 patients with psychotic illness, 123 siblings and 72 controls. ChM was assessed with the Childhood Trauma Questionnaire (CTQ). Attachment dimensions of anxiety and avoidance were measured using the Psychosis Attachment Measure (PAM). In both patients and siblings, ChM predicted positive symptoms and this relationship was partly mediated by attachment style. This relationship was found to be stronger for siblings than for patients. ChM predicted negative symptoms in patients and siblings. In the patient sample, attachment style did not mediate the relationship between ChM and negative symptoms, whereas attachment style was found to be a mediator in the sibling sample. ChM was associated with positive and negative symptomatology in both patients and siblings. Particularly in siblings, the relationship between ChM and psychosis seems to be mediated by adult attachment style. Perhaps attachment style may play a more prominent role on a subclinical level.

Psychotic Experiences and Working Memory: A Population-Based Study Using Signal-Detection Analysis.

Rodolfo Rossi

Full Text Available Psychotic Experiences (PEs during adolescence index increased risk for psychotic disorders and schizophrenia in adult life. Working memory (WM deficits are a core feature of these disorders. Our objective was to examine the relationship between PEs and WM in a general population sample of young people in a case control study. 4744 individuals of age 17-18 from Bristol and surrounding areas (UK were analyzed in a cross-sectional study nested within the Avon Longitudinal Study of Parents and Children (ALSPAC birth cohort study. The dependent variable was PEs, assessed using the semi-structured Psychosis-Like Symptom Interview (PLIKSi. The independent variable was performance on a computerized numerical n-back working memory task. Signal-Detection Theory indices, including standardized hits rate, false alarms rate, discriminability index (d' and response bias (c from 2-Back and 3-Back tasks were calculated. 3576 and 3527 individuals had complete data for 2-Back and 3-Back respectively. Suspected/definite PEs prevalence was 7.9% (N = 374. Strongest evidence of association was seen between PEs and false alarms on the 2-Back, (odds ratio (OR = 1.17 [95% confidence intervals (CI 1.01, 1.35] and 3-back (OR = 1.35 [1.18, 1.54] and with c (OR = 1.59 [1.09, 2.34], and lower d' (OR = 0.76 [0.65, 0.89], on the 3-Back. Adjustment for several potential confounders, including general IQ, drug exposure and different psycho-social factors, and subsequent multiple imputation of missing data did not materially alter the results. WM is impaired in young people with PEs in the general population. False alarms, rather than poor accuracy, are more closely related to PEs. Such impairment is consistent with different neuropsychological models of psychosis focusing on signal-to-noise discrimination, probabilistic reasoning and impaired reality monitoring as a basis of psychotic symptoms.

The comparison of the locus of control in groups of patients hospitalised due to alcohol withdrawal with and without delirium and analysis of psychotic experiences of patients with delirium. 25 patients with alcohol withdrawal with delirium and 25 without delirium took part in the study. They filled-in the Internal-External (I-E) Locus of Control Scale by Rotter; Multidimensional Health Locus of Control (MHLC) scale; the group with delirium also did the Psychopathological Symptoms Inventory, by Bizoń et al. The mean score in I-E Locus of Control Scale in the group with delirium was more external than in the group without delirium (M = 13.28; SD = 2.762 versus M = 11.64; SD = 2.612; t(48) = -2.157; p = 0.036). Group with delirium had also lower mean score in the dimension of internal control in MHLC, than the group without delirium (M = 24.8; SD = 6.149 versus M = 26.8; SD = 4.648; t(48) = 1.99; p = 0.04). There were no statistically significant differences between the groups in the other subscales. The auditory and visual hallucinations were most common among patients with delirium (84%, 80% respectively, as well as delusions of taking part in not existing events (92%) and persecutory delusions (80%). Psychotic experiences influenced behaviour in nearly 50% of the cases. A more external locus of control may be one of the factors contributing to the development of alcohol delirium. The content of psychotic experiences seems to have impact on the behaviour of many patients with alcohol delirium.

Evidence suggests that in affective, non-psychotic disorders: (i) environmental exposures increase risk of subthreshold psychotic experiences (PEs) and strengthen connectivity between domains of affective and subthreshold psychotic psychopathology; and (ii) PEs are a marker of illness severity. In 3021 adolescents from the Early Developmental Stages of Psychopathology cohort, we tested whether the association between PEs and presence of DSM-IV mood disorder (MD)/obsessive-compulsive disorder (OCD) would be moderated by risk factors for psychosis (cannabis use, childhood trauma and urbanicity), using the interaction contrast ratio (ICR) method. Furthermore, we analysed whether the interaction between environment and PEs was mediated by non-psychotic psychopathology. The association between PEs and MD/OCD was moderated by urbanicity (ICR = 2.46, p = 0.005), cannabis use (ICR = 3.76, p = 0.010) and, suggestively, trauma (ICR = 1.91, p = 0.063). Exposure to more than one environmental risk factor increased the likelihood of co-expression of PEs in a dose-response fashion. Moderating effects of environmental exposures were largely mediated by the severity of general non-psychotic psychopathology (percentage explained 56-68%, all p psychopathology. The findings are compatible with a relational model of psychopathology in which more severe clinical states are the result of environment-induced disturbances spreading through a psychopathology network.

Protective Factors for Psychotic Symptoms Among Poly-victimized Children.

Experiencing victimization in early life has been repeatedly shown to be associated with the emergence of psychotic symptoms in childhood. However, most victimized children do not develop psychotic symptoms and why this occurs is not fully understood. This study investigated which individual, family-level, and wider community characteristics were associated with an absence of psychotic symptoms among children at risk for psychosis by virtue of their exposure to multiple victimization experiences (poly-victimization). Participants were from the Environmental Risk Longitudinal Twin Study, a nationally representative cohort of 2232 UK-born twins. Exposure to maltreatment, bullying and domestic violence prior to age 12 was determined from interviews with mothers, children, and observations by research workers at ages 5, 7, 10, and 12. Children were interviewed about psychotic symptoms at age 12. Protective factors were measured at ages 5, 7, 10, and 12. Childhood poly-victimization was associated with age-12 psychotic symptoms (OR = 4.61, 95% CI 2.82-7.52), but the majority of poly-victimized children did not report symptoms (80.7%). Having a relatively high IQ, more positive atmosphere at home, and higher levels of neighborhood social cohesion were found to be protective against childhood psychotic symptoms among poly-victimized children and also in the whole sample. However, "protected" poly-victimized children displayed elevated levels of other mental health problems compared to nonvictimized children. Children's characteristics, family context, and the wider community were all found to protect children from developing early psychotic symptoms, even when they were victimized multiple times. These findings indicate targets for multilevel preventive interventions.

Psychosis is hypothesized to occur on a spectrum between psychotic disorders and healthy individuals. In the middle of the spectrum are individuals who endorse psychotic-like experiences (PLEs) that may not impact daily functioning or cause distress. Individuals with PLEs show alterations in both cognitive ability and functional connectivity of several brain networks, but the relationship between PLEs, cognition, and functional networks remains poorly understood. We analyzed resting-state fMRI data, a range of neuropsychological tasks, and questions from the Achenbach Adult Self Report (ASR) in 468 individuals from the Human Connectome Project. We aimed to determine whether global efficiency of specific functional brain networks supporting higher-order cognition (the fronto-parietal network (FPN), cingulo-opercular network (CON), and default mode network (DMN)) was associated with PLEs and cognitive ability in a non-psychiatric sample. 21.6% of individuals in our sample endorsed at least one PLE. PLEs were significantly negatively associated with higher-order cognitive ability, CON global efficiency, and DMN global efficiency, but not crystallized knowledge. Higher-order cognition was significantly positively associated with CON and DMN global efficiency. Interestingly, the association between PLEs and cognitive ability was partially mediated by CON global efficiency and, in a subset of individuals who tested negative for drugs (N=405), the participation coefficient of the right anterior insula (a hub within the CON). These findings suggest that CON integrity may represent a shared mechanism that confers risk for psychotic experiences and the cognitive deficits observed across the psychosis spectrum.

Recent research indicates that subclinical social anxiety is associated with dysfunctions at multiple psychological and biological levels, in a manner that seems reminiscent of social anxiety disorder (SAD). This study aimed to describe multidimensional responses to laboratory-induced social stress in an analog sample selected for social anxiety symptoms. State anxiety, cognitive biases related to negative social evaluation, speech anxiety behaviors, and cortisol reactivity were assessed in the Trier Social Stress Test (TSST). Results showed that social anxiety symptoms were associated with increased state anxiety, biased appraisals related to the probability and cost of negative social evaluations, behavioral changes in facial expression that were consistent with speech anxiety, and lower cortisol reactivity. In addition, multiple interrelations between responses in the TSST were found, with positive associations between subjective experience, cognitive appraisals, and observable behavior, as well as negative associations between each of the former two types of response and cortisol reactivity. These results show that in response to social stressors, subclinical social anxiety is associated with significant changes in emotional experience, cognitive appraisals, behaviors, and physiology that could parallel those previously found in SAD samples.

Cella, Matteo; Vellante, Marcello; Preti, Antonio

2012-09-01

Paranormal beliefs and Psychotic-like Experiences (PLE) are phenotypically similar and can occur in individuals with psychosis but also in the general population; however the relationship of these experiences for psychosis risk is largely unclear. This study investigates the association of PLE and paranormal beliefs with psychological distress. Five hundred and three young adults completed measures of paranormal beliefs (Beliefs in the Paranormal Scale), psychological distress (General Health Questionnaire), delusion (Peters et al. Delusions Inventory), and hallucination (Launay-Slade Hallucination Scale) proneness. The frequency and intensity of PLE was higher in believers in the paranormal compared to non-believers, however psychological distress levels were comparable. Regression findings confirmed that paranormal beliefs were predicted by delusion and hallucination-proneness but not psychological distress. The use of a cross-sectional design in a specific young adult population makes the findings exploratory and in need of replication with longitudinal studies. The predictive value of paranormal beliefs and experiences for psychosis may be limited; appraisal or the belief emotional salience rather than the belief per se may be more relevant risk factors to predict psychotic risk.

Zamrazil, V

2007-01-01

Subclinical thyroids disease (STD) is recently defined term in clinical thyroidology, which includes mainly functional disorders. Basic diagnostic signs are: normal values of thyroid hormones (fT4, fT3) and elevated TSH level (subclinical hypothyroidism) or suppresed TSH level (subclinical hyperthyroidism). In a category of STD may be included subclinical autoimunne thyroiditis (elevated level of thyroid antigens antibodies and/or hypoechogenity in sonographic screen, increased volume of the thyroid without clinical symptoms and/or autoimminity) and microscopic lesions of papillary thyroid carcinoma. Subclinical hypothyroidism may be dangerous for tendency to development of manifest hypothyroidism and for risk of disorders of lipid profile and development of atherosclerosis and its organ complication (esp. myocardial infarction). Subclinical hyperthyroidism is a risk factor of cardiac arythmias and probably can increase a risk of cardiovascular mortality) as well for osteoporosis (esp. in peri- and post-climacteric women), and last but not least for degenerative diseases of brain (?). Indication of treatment of STD is a matter of controversies. Recomendations of experts, varied from "no therapy, monitoring only" to "treat always". Treatment of risk groups (esp. pregnant women) is probably nowadays a most rationale recommendations since results of sofisticated prospective studies will be available.

Various clinical disorders, including psychopathy, and autism and schizophrenia spectrum disorders, have been linked with impairments in Theory of Mind (ToM). However, although these conditions can co-occur in the same individual, the effect of their inter-play on ToM abilities has not been investigated. Here we assessed ToM abilities in 55 healthy adults while performing a naturalistic ToM task, requiring participants to watch a short film and judge the actors' mental states. The results reveal for the first time that autistic traits and positive psychotic experiences interact with psychopathic tendencies in opposite directions to predict ToM performance-the interaction of psychopathic tendencies with autism traits was associated with a decrement in performance, whereas the interaction of psychopathic tendencies and positive psychotic experiences was associated with improved performance. These effects were specific to cognitive rather than affective ToM. These results underscore the importance of the simultaneous assessment of these dimensions within clinical settings. Future research in these clinical populations may benefit by taking into account such individual differences.

OBJECTIVE: Psychotic depression (PD) is a highly debilitating condition, which needs intensive monitoring. However, there is no established rating scale for evaluating the severity of PD. The aim of this analysis was to assess the psychometric properties of established depression rating scales...... and a number of new composite rating scales, covering both depressive and psychotic symptoms, in relation to PD. METHOD: The psychometric properties of the rating scales were evaluated based on data from the Study of Pharmacotherapy of Psychotic Depression. RESULTS: A rating scale consisting of the 6-item......'s correlation coefficient between change in HAMD-BPRS11 and Clinical Global Impression - Improvement (CGI-I) scores = -0.74--0.78) and unidimensionality (Loevinger's coefficient of homogeneity = 0.41) in the evaluation of PD. The HAM-D6 fulfilled the same criteria, whereas the full 17-item Hamilton Depression...

How to tell a happy from an unhappy schizotype: personality factors and mental health outcomes in individuals with psychotic experiences

Directory of Open Access Journals (Sweden)

Letícia O. Alminhana

Full Text Available Objective: It is unclear why some individuals reporting psychotic experiences have balanced lives while others go on to develop mental health problems. The objective of this study was to test if the personality traits of harm avoidance, self-directedness, and self-transcendence can be used as criteria to differentiate healthy from unhealthy schizotypal individuals. Methods: We interviewed 115 participants who reported a high frequency of psychotic experiences. The instruments used were the Temperament and Character Inventory (140, Structured Clinical Interview for DSM-IV, and the Oxford-Liverpool Inventory of Feelings and Experiences. Results: Harm avoidance predicted cognitive disorganization (β = 0.319; t = 2.94, while novelty seeking predicted bipolar disorder (β = 0.136, Exp [β] = 1.146 and impulsive non-conformity (β = 0.322; t = 3.55. Self-directedness predicted an overall decrease in schizotypy, most of all in cognitive disorganization (β = -0.356; t = -2.95 and in impulsive non-conformity (β = -0.313; t = -2.83. Finally, self-transcendence predicted unusual experiences (β = 0.256; t = 2.32. Conclusion: Personality features are important criteria to distinguish between pathology and mental health in individuals presenting high levels of anomalous experiences (AEs. While self-directedness is a protective factor, both harm avoidance and novelty seeking were predictors of negative mental health outcomes. We suggest that the impact of AEs on mental health is moderated by personality factors.

There have been several attempts to identify individuals potentially at high risk for psychotic-spectrum disorders using brief screening measures. However, relatively few studies have tested the psychometric properties of the psychosis screening measures in representative samples of adolescents. The main purpose of the present study was to analyse the prevalence, factorial structure, measurement invariance across gender, and reliability of the Youth Psychosis At-Risk Questionnaire - Brief (YPARQ-B) in a community-derived sample of adolescents. Additionally, the relationship between YPARQ-B, depressive symptoms, psychopathology, stress manifestations, and prosocial skills was analysed. One thousand and twenty students from high schools participated in a cross-sectional survey. The YPARQ-B, the Reynolds Adolescent Depression Scale, the Strengths and Difficulties Questionnaire, and the Student Stress Inventory - Stress Manifestations were used. A total of 85.1% of the total sample self-reported at least one subclinical psychotic experience. We observed a total of 10.9% of adolescents with a cutoff score of ≥11 or 6.8% with a cutoff score of ≥13. The analysis of internal structure of the YPARQ-B yielded an essentially unidimensional structure. The YPARQ-B scores showed measurement invariance across gender. The internal consistency of the YPARQ-B total score was 0.94. Furthermore, self-reported subclinical psychotic experiences were associated with depressive symptoms, emotional and behavioural problems, poor prosocial skills, and stress manifestations. These results would appear to indicate that YPARQ-B is a brief and easy tool to assess self-reported subclinical psychotic experiences in adolescents from the general population. The assessment of these experiences in community settings, and its associations with psychopathology, may help us to enhance the possibility of an early identification of adolescents potentially at risk for psychosis and mental health

Full Text Available ABSTRACT Objective. The aim of this field trial was to investigate the relationships among subclinical laminitis, hematological, ruminal and faecal alterations. Materials and Methods. To this extent dairy cows presenting subclinical laminitis (n=11 and to those of other healthy cows without laminitis (n=10 were enrolled and assigned into two groups. All animals were receiving the same daily ration formulated to contain 47% cornsilage and 18% hay, mainly. Effects of subclinical laminitis challenges on measurements of feces, and blood samples, were investigated to determine which of these measurements may aid in the diagnosis. pH changes in ruminal fluid collected via rumenocentesis were measured. Besides the following parameters were also measured; blood pH, faecal pH and faecal scoring. Blinded investigators performed the sample collection. Results. No statistical differences between the groups were detected for blood gas values studied regarding pCO2, HCO3, BE, indeed mean that pO2 values decreased statistically (p<0.05 and faecal pH was significantly decreased (p<0.05 in cows with subclinical laminitis in contrast to healthy controls. Conclusions. pO2 values and faecal pH may be valuable as indirect indicators of subclinical laminitis in cattle.

"Living turned inside out": the musical expression of psychotic and schizoid experience in talking heads' Remain in light.

Brog, Michael A

2002-06-01

The rock album form, advantageously suited for the artistic expression of intrapsychic experience, has been virtually ignored by analytic writers. Remain in Light by Talking Heads is presented as an example of an album that effectively utilizes the potentialities of this form to give powerful and disconcerning musical expression to a variety of psychotic and schizoid experiences, bringing to life the formulations for these phenomena of Bion, Winnicott, Guntrip, Ogden, Grotstein and others. The album suggests a variety of mechanisms by which sound and music may serve both defensive and compensatory functions in relation to these phenomena.

The authors sought to model the different trajectories of psychotic-like experiences (PLE) during adolescence and to examine whether the longitudinal relationship between cannabis use and PLE is mediated by changes in cognitive development and/or change in anxiety or depression symptoms. A total of 2,566 youths were assessed every year for 4-years (from 13- to 16-years of age) on clinical, substance use and cognitive development outcomes. Latent class growth models identified three trajectories of PLE: low decreasing (83.9%), high decreasing (7.9%), and moderate increasing class (8.2%). We conducted logistic regressions to investigate whether baseline levels and growth in cannabis use were associated with PLE trajectory membership. Then, we examined the effects of potential mediators (growth in cognition and anxiety/depression) on the relationship between growth in cannabis use and PLE trajectory. A steeper growth in cannabis use from 13- to 16-years was associated with a higher likelihood of being assigned to the moderate increasing trajectory of PLE [odds ratio, 2.59; 95% confidence interval (CI), 1.11-6.03], when controlling for cumulative cigarette use. Growth in depression symptoms, not anxiety or change in cognitive functioning, mediated the relationship between growth in cannabis use and the PLE moderate increasing group (indirect effect: 0.07; 95% CI, 0.03-0.11). Depression symptoms partially mediated the longitudinal link between cannabis use and PLE in adolescents, suggesting that there may be a preventative effect to be gained from targeting depression symptoms, in addition to attempting to prevent cannabis use in youth presenting increasing psychotic experiences. © 2017 Association for Child and Adolescent Mental Health.

In clinical settings, there is substantial evidence both clinically and empirically to suggest that approximately 50% of individuals with borderline personality disorder experience auditory verbal hallucinations. However, there is limited research investigating the phenomenology of these voices. The aim of this study was to review and compare our current understanding of auditory verbal hallucinations in borderline personality disorder with auditory verbal hallucinations in patients with a psychotic disorder, to critically analyse existing studies investigating auditory verbal hallucinations in borderline personality disorder and to identify gaps in current knowledge, which will help direct future research. The literature was searched using the electronic database Scopus, PubMed and MEDLINE. Relevant studies were included if they were written in English, were empirical studies specifically addressing auditory verbal hallucinations and borderline personality disorder, were peer reviewed, used only adult humans and sample comprising borderline personality disorder as the primary diagnosis, and included a comparison group with a primary psychotic disorder such as schizophrenia. Our search strategy revealed a total of 16 articles investigating the phenomenology of auditory verbal hallucinations in borderline personality disorder. Some studies provided evidence to suggest that the voice experiences in borderline personality disorder are similar to those experienced by people with schizophrenia, for example, occur inside the head, and often involved persecutory voices. Other studies revealed some differences between schizophrenia and borderline personality disorder voice experiences, with the borderline personality disorder voices sounding more derogatory and self-critical in nature and the voice-hearers' response to the voices were more emotionally resistive. Furthermore, in one study, the schizophrenia group's voices resulted in more disruption in daily functioning

Post-psychotic depression in schizophrenia.

Chintalapudi, M; Kulhara, P; Avasthi, A

1993-01-01

Post-psychotic depression (PPD) is defined as the development of depression during the phase of remission of schizophrenia. Two groups of DSM-III-R schizophrenics, one with PPD and the other without PPD (30 subjects in each group) were compared. Significantly more patients in PPD group belonged to nuclear families, had longer duration of psychotic phase of the illness, were hospitalised more frequently and had more sadness and anxiety-somatisation during florid illness phase. The PPD group also had more past history of depression. Although PPD patients had better premorbid personal-social adjustment in comparison with non-PPD group, they perceived themselves to be lacking in social support and had experienced more stressful life events. For patients in the PPD group, stepwise multiple regression analysis revealed age of onset, sadness during florid psychotic state, premorbid adjustment, social support and life events as significant determinants of severity of depression in the post-psychotic phase.

Khat use, PTSD and psychotic symptoms among Somali refugees in Nairobi - a pilot study

Full Text Available In East-African and Arab countries, khat leaves are traditionally chewed in social settings. They contain the amphetamine-like alkaloid cathinone. Especially among Somali refugees khat use has been associated with psychiatric symptoms. We assessed khat use patterns and psychiatric symptoms among male Somali refugees living in a disadvantaged urban settlement area in Kenya, a large group that has not yet received scientific attention. We wanted to explore consume patterns and study the associations between khat use, traumatic experiences and psychotic symptoms.Using privileged access sampling we recruited 33 healthy male khat chewers and 15 comparable non-chewers. Based on extensive preparatory work, we assessed khat use, khat dependence according to DSM-IV, traumatic experiences, Posttraumatic Stress Disorder and psychotic symptoms using standardized diagnostic instruments that had been adapted to the Somali language and culture.Hazardous use patterns like chewing for more than 24 hours without interruption were frequently reported. All khat users fulfilled the DSM-IV-criteria for dependence and eighty-five percent reported functional khat-use, i.e. that khat helps them to forget painful experiences. We found that the studied group was heavily burdened by traumatic events and posttraumatic symptoms. Khat users had experienced more traumatic events and had more often PTSD than non-users. Most khat users experience khat-related psychotic symptoms and in a quarter of them we found true psychotic symptoms. In contrast, among control group members no psychotic symptoms could be detected.We found first evidence for the existence and high prevalence of severely hazardous use patterns, comorbid psychiatric symptoms and khat use as a self-medication of trauma-consequences among male Somali refugees in urban Kenyan refugee settlements. There is a high burden by psychopathology and adequate community-based interventions urgently need to be developed.

We retrospectively examined the outcome of patients who underwent laparoscopic adrenalectomy for Cushing's/subclinical Cushing's syndrome in our single institute. Between 1994 and 2008, a total of 114 patients (29 males and 85 females, median age 54 years) with adrenal Cushing's/subclinical Cushing's syndrome were studied. We compared the outcome of patients who underwent laparoscopic adrenalectomy between intraperitoneal and retroperitoneal approaches. Surgical complications were graded according to the Clavien grading system. We also examined the long-term results of subclinical Cushing's syndrome after laparoscopic adrenalectomy. Laparoscopic surgical outcome did not differ significantly between patients with Cushing's syndrome and those with subclinical Cushing's syndrome. Patients who underwent laparoscopic intraperitoneal adrenalectomy had longer operative time than those who received retroperitoneal adrenalectomy (188.2 min vs. 160.9 min). However, operative blood loss and surgical complications were similar between both approaches. There were no complications of Clavien grade III or higher in either intraperitoneal or retroperitoneal approach. We confirmed the improvement of hypertension and glucose tolerance in patients with subclinical Cushing's syndrome after laparoscopic adrenalectomy. Laparoscopic adrenalectomy for adrenal Cushing's/subclinical Cushing's syndrome is safe and feasible in either intraperitoneal or retroperitoneal approach. The use of the Clavien grading system for reporting complications in the laparoscopic adrenalectomy is encouraged for a valuable quality assessment.

Social anxiety commonly occurs across the course of schizophrenia, including in the premorbid and prodromal phases of psychotic disorders. Some have posited that social anxiety may exist on a continuum with paranoia; however, empirical data are lacking. The study aim was to determine whether attenuated positive psychotic symptoms are related to social anxiety. Young adults (N=1378) were administered the Prodromal Questionnaire (PQ), which measures attenuated positive psychotic symptoms (APPS), and the Social Phobia Scale (SPS), which measures a subset of social anxiety symptoms. Confirmatory factor analyses were conducted to address the extent to which social anxiety and APPS tap distinct dimensions. Confirmatory factor analyses support the existence of a separate social anxiety factor scale and four separate, though interrelated, APPS factor domains (unusual thought content, paranoia/suspiciousness, disorganized thinking, and perceptual abnormalities). Additionally, social anxiety was significantly, but not differently related to each APPS domain, although the magnitude was reduced between social anxiety and distressing APPS. The current study suggests that social anxiety and attenuated positive psychotic symptoms are separable constructs, but are significantly associated with each other.

Motives for offending among violent and psychotic men.

Science.gov (United States)

Taylor, P J

1985-11-01

Two hundred and three male remanded prisoners were interviewed with respect to their current offence, mental state, and social and psychiatric histories. All but nine of the sub-group of 121 psychotic men showed active symptoms at the time of committing a criminal offence; 20% of the actively ill psychotics were directly driven to offend by their psychotic symptoms, and a further 26% probably so. If some of the indirect consequences of the psychosis were taken into account, 82% of their offences were probably attributable to the illness. Among the normal and neurotic men, none claimed psychotic motives for offending, but motives suggesting high emotional arousal such as panic or retaliation triggered the greatest violence. Within the psychotic group, those driven to offend by their delusions were most likely to have been seriously violent, and psychotic symptoms probably accounted directly for most of the very violent behaviour.

[Subclinical hyperthyroidism: from diagnosis to treatment].

Science.gov (United States)

Corvilain, B

2012-09-01

Subclinical hyperthyroidism is a common clinical entity. Subclinical hyperthyroidism is defined as a serum TSH below the reference range but a normal T4 and T3 level in an asymptomatic patient. Whether or not subclinical hyperthyroidism should be treated remains a matter of debate. Cross-sectional studies and longitudinal population-based studies demonstrate association between subclinical hyperthyroidism and risk of atrial fibrillation, osteoporosis and cardiovascular and global mortality. However, there are no randomized clinical trials answering the question whether long term-health outcomes are improved by the treatment of subclinical hyperthyroidism. Therefore in the absence of evidence for or against treatment of subclinical hyperthyroidism, it seems appropriate to follow algorithms that consider the level of TSH and the presence of risks factors (age > 65 years, osteoporosis, post menopause and cardiac disease).

Subclinical Cushing's syndrome is a condition of hypercortisolism in the absence of signs specific of overt cortisol excess, and it is associated with an increased risk of diabetes, hypertension, fragility fractures, cardiovascular events and mortality. The subclinical Cushing's syndrome is not rare, being estimated to be between 0.2-2 % in the adult population. Despite the huge number of studies that have been published in the recent years, several issues remain controversial for the subclinical Cushing's syndrome screening, diagnosis and treatment. The Altogether to Beat Cushing's syndrome Group was founded in 2012 for bringing together the leading Italian experts in the hypercortisolism-related diseases. This document represents the Altogether to Beat Cushing's syndrome viewpoint regarding the following controversial issues on Subclinical Cushing's syndrome (SCS): (1) Who has to be screened for subclinical Cushing's syndrome? (2) How to screen the populations at risk? (3) How to diagnose subclinical Cushing's syndrome in patients with an adrenal incidentaloma? (4) Which consequence of subclinical Cushing's syndrome has to be searched for? (5) How to address the therapy of choice in AI patients with subclinical Cushing's syndrome? (6) How to follow-up adrenal incidentaloma patients with subclinical Cushing's syndrome surgically or conservatively treated? Notwithstanding the fact that most studies that faced these points may have several biases (e.g., retrospective design, small sample size, different criteria for the subclinical Cushing's syndrome diagnosis), we believe that the literature evidence is sufficient to affirm that the subclinical Cushing's syndrome condition is not harmless and that the currently available diagnostic tools are reliable for identifying the majority of individuals with subclinical Cushing's syndrome.

We examined the lifetime experience of hallucinations and delusions associated with transient methamphetamine-related psychosis (MAP), persistent MAP and primary psychosis among a cohort of dependent methamphetamine users. Participants were classified as having (a) no current psychotic symptoms, (n=110); (b) psychotic symptoms only when using methamphetamine (transient MAP, n=85); (c) psychotic symptoms both when using methamphetamine and when abstaining from methamphetamine (persistent MAP, n=37), or (d) meeting DSM-IV criteria for lifetime schizophrenia or mania (primary psychosis, n=52). Current psychotic symptoms were classified as a score of 4 or more on any of the Brief Psychiatric Rating Scale items of suspiciousness, hallucinations or unusual thought content in the past month. Lifetime psychotic diagnoses and symptoms were assessed using the Composite International Diagnostic Interview. Transient MAP was associated with persecutory delusions and tactile hallucinations (compared to the no symptom group). Persistent MAP was additionally associated with delusions of reference, thought interference and complex auditory, visual, olfactory and tactile hallucinations, while primary psychosis was also associated with delusions of thought projection, erotomania and passivity. The presence of non-persecutory delusions and hallucinations across various modalities is a marker for persistent MAP or primary psychosis in people who use methamphetamine. Copyright © 2017.

Full Text Available Abstract Background Little is known about the prevalence of khat-induced psychotic disorders in East African countries, where the chewing of khat leaves is common. Its main psycho-active component cathinone produces effects similar to those of amphetamine. We aimed to explore the prevalence of psychotic disorders among the general population and the association between khat use and psychotic symptoms. Methods In an epidemiological household assessment in the city of Hargeisa, North-West Somalia, trained local interviewers screened 4,854 randomly selected persons from among the general population for disability due to severe mental problems. The identified cases were interviewed based on a structured interview and compared to healthy matched controls. Psychotic symptoms were assessed using the items of the WHO Composite International Diagnostic Interview and quantified with the Positive and Negative Symptoms Scale. Statistical testing included Student's t-test and ANOVA. Results Local interviewers found that rates of severe disability due to mental disorders were 8.4% among males (above the age of 12 and differed according to war experiences (no war experience: 3.2%; civilian war survivors: 8.0%; ex-combatants: 15.9%. The clinical interview verified that in 83% of positive screening cases psychotic symptoms were the most prominent manifestations of psychiatric illness. On average, cases with psychotic symptoms had started to use khat earlier in life than matched controls and had been using khat 8.6 years before positive symptoms emerged. In most cases with psychotic symptoms, a pattern of binge use (> two 'bundles' per day preceded the onset of psychotic symptoms, in contrast to controls of the same age. We found significant correlations between variables of khat consumption and clinical scales (0.35 to 0.50; p Conclusion Evidence indicates a relationship between the consumption of khat and the onset of psychotic symptoms among the male

The association between borderline personality disorder and the ultra high risk (UHR) for psychosis state is unclear. The following study aimed to investigate the type of attenuated psychotic symptoms and prevalence of borderline personality pathology in a sample of UHR young people. Additionally, the study aimed to explore whether borderline personality pathology influenced the transition rate to psychosis. Medical records from Orygen Youth Health between 2007 and 2009 were examined. There were 180 patients who met UHR criteria and were included for analysis. Most patients were females (62.8%) and age ranged from 15 to 24 years. A quarter (25.2%) of UHR patients endorsed items consistent with borderline personality pathology. UHR patients with borderline personality pathology experienced a range of attenuated psychotic symptoms and could not be statistically differentiated from UHR patients with less significant or without borderline personality pathology. Borderline personality pathology did not increase or decrease the risk of developing a psychotic disorder. The absence of depression was the only predictor of psychosis. Many UHR patients present with concurrent borderline personality features. The psychotic experiences reported by UHR patients with borderline personality features were not limited to paranoid ideation, supporting the idea that borderline personality disorder may include a wider range of psychotic symptoms than previously thought. It is further possible that the psychotic symptoms experienced in this group could also be indicative of an emerging psychotic disorder. © 2015 Wiley Publishing Asia Pty Ltd.

A population-based study of atopic disorders and inflammatory markers in childhood before psychotic experiences in adolescence.

Schizophrenia is associated with atopy and increased inflammatory markers. We report a population-based longitudinal study of the associations between childhood atopic disorders, subsequent serum inflammatory markers, interleukin 6 (IL-6) and C-reactive protein (CRP), and the risk of psychotic experiences (PEs). PEs were assessed at age 13 years (n=6785). Presence of clinician-diagnosed atopic disorders (asthma and eczema) was determined from parent-completed questionnaires at age 10 years (n=7814). Serum IL-6 and CRP were measured at age 9 years (n=5076). Logistic regression examined the association between (1) atopy and PEs, (2) inflammatory markers and PEs, and (3) mediating effects of inflammatory markers on the atopy-PEs association. Linear regression examined the association between atopy and inflammatory markers. Age, gender, social class, ethnicity and body mass index were included as potential confounders. At age 10 years, about 14% of the sample was reported to have asthma, 12% eczema, and 7% both asthma and eczema. Compared with children with no atopy, risk of PEs at age 13 years was increased for all of these groups; adjusted odds ratios (95% CI) were, respectively, 1.39 (1.10-1.77), 1.33 (1.04-1.69), and 1.44 (1.06-1.94). Atopy was associated with increased serum IL-6 and CRP; however, this did not mediate association between atopy and PEs. Inflammatory markers were not associated with later PEs. Childhood atopic disorders increase the risk of psychotic experiences in adolescence. Follow-up of these individuals will be useful to determine the effect of atopy and inflammation on different trajectories of early-life PEs. © 2013. Published by Elsevier B.V. All rights reserved.

BACKGROUND: Severe unipolar depression is associated with increased risk of suicide, but it remains unknown whether the same risk factors are present in the non-psychotic (non-PD) and psychotic (PD) subtypes respectively. Therefore, this study aimed to identify risk factors for suicide in non......-PD and PD separately, and to investigate if the presence of psychotic symptoms is an independent risk factor for suicide in severe depression. METHODS: This register-based, nationwide, historical prospective cohort study used logistic regression analyses to ascertain risk factors for suicide among all...... adults diagnosed with severe depression at Danish psychiatric hospitals between January 1, 1994 and December 31, 2010. The risk for suicide was expressed as adjusted odds ratios (AOR). RESULTS: A total of 34,671 individuals with severe depression (non-PD: n=26,106 and PD: n=12,101) were included...

Different forms of artistic expression, such as literature and cinema, constitute an inexhaustible source for the study of mental illness. The use of psychodynamic models may contribute to a better understanding of the spectrum between personality disorders and the psychosis spectrum, thus enriching the phenomenological approach in the psychiatric clinical practice. To examine from psychodynamic standpoints the main character of the American film Black Swan, and the nature of her psychotic symptoms. Reviewing of sources and relevant theoretical currents. Analysis shows the usefulness of a psychodynamically- oriented dimensional model for understanding the so-called psychotic breaks as well as the applicability of psychoanalytic psychosis theories in general psychiatric practice, as they may provide a more flexible clinical approach, closer to the patient's subjective experience.

The projected hand illusion (PHI) is a variant of the rubber hand illusion (RHI), and both are commonly used to study mechanisms of self-perception. A questionnaire was developed by Longo et al. (2008) to measure qualitative changes in the RHI. Such psychometric analyses have not yet been conducted on the questionnaire for the PHI. The present study is an attempt to validate minor modifications of the questionnaire of Longo et al. to assess the PHI in a community sample (n = 48) and to determine the association with selected demographic (age, sex, years of education), cognitive (Digit Span), and clinical (psychotic-like experiences) variables. Principal components analysis on the questionnaire data extracted four components: Embodiment of "Other" Hand, Disembodiment of Own Hand, Deafference, and Agency-in both synchronous and asynchronous PHI conditions. Questions assessing "Embodiment" and "Agency" loaded onto orthogonal components. Greater illusion ratings were positively associated with being female, being younger, and having higher scores on psychotic-like experiences. There was no association with cognitive performance. Overall, this study confirmed that self-perception as measured with PHI is a multicomponent construct, similar in many respects to the RHI. The main difference lies in the separation of Embodiment and Agency into separate constructs, and this likely reflects the fact that the "live" image of the PHI presents a more realistic picture of the hand and of the stroking movements of the experimenter compared with the RHI.

Background Schizophrenia has a neurodevelopmental component to its origin, and may share overlapping pathogenic mechanisms with childhood neurodevelopmental disorders (ND). Yet longitudinal studies of psychotic outcomes among individuals with ND are limited. We report a population-based prospective study of six common childhood ND, subsequent neurocognitive performance and the risk of psychotic experiences (PEs) in early adolescence. Methods PEs were assessed by semi-structured interviews at age 13 years. IQ and working memory were measured between ages 9 and 11 years. The presence of six neurodevelopmental disorders (autism spectrum, dyslexia, dyspraxia, dysgraphia, dysorthographia, dyscalculia) was determined from parent-completed questionnaire at age 9 years. Linear regression calculated mean difference in cognitive scores between those with and without ND. The association between ND and PEs was expressed as odds ratio (OR); effects of cognitive deficits were examined. Potential confounders included age, gender, father’s social class, ethnicity and maternal education. Results Out of 8,220 children, 487 (5.9%) were reported to have ND at age 9 years. Children with, compared with those without ND performed worse on all cognitive measures; adjusted mean difference in total IQ 6.84 (95% CI 5.00- 8.69). The association between total IQ and ND was linear (pneurodevelopmental hypothesis of schizophrenia. PMID:25066026

Redford, Christopher; Vaidya, Bijay

2017-06-01

Subclinical hypothyroidism (also known as compensated hypothyroidism or mild hypothyroidism) is a condition associated with a raised serum concentration of thyroid stimulating hormone (TSH) but a normal serum free thyroxine (FT4). It is common, affecting about 10% of women above the age of 55 years. Autoimmunity is the commonest cause of subclinical hypothyroidism. About 2.5% of patients with subclinical hypothyroidism progress to clinically overt hypothyroidism each year; the rate of progression is higher in patients with thyroid autoantibodies and higher thyroid stimulating hormone levels. However, thyroid function normalises spontaneously in up to 40% cases. Only a small minority of patients with subclinical hypothyroidism have symptoms, and the evidence to support that levothyroxine ameliorate the symptoms in these patients is weak. Subclinical hypothyroidism in younger patients (treatment can prevent these risks, although a large observational study of the UK general practice research database has shown that levothyroxine may reduce the risk of coronary heart disease in younger patients (hypothyroidism should be made after careful consideration of the patient's age, the presence of symptoms, the presence of thyroid antibodies and other risk factors such as cardiovascular disease.

Psychotic-like experiences and happiness in the English general population.

Koyanagi, Ai

2017-11-01

Psychotic-like experiences (PLEs) have been associated with a variety of adverse outcomes but how they affect happiness in individuals with PLE is unknown. Thus, the aim of the study was to assess the association between PLEs and happiness, and the factors that may influence this association. Nationally representative data from the 2007 Adult Psychiatric Morbidity Survey including adults aged ≥ 16 years was analyzed. The Psychosis Screening Questionnaire was used to assess past 12-month PLE. Individuals who endorsed at least one of the following were considered to have any PLE: thought control, paranoia, strange experiences, auditory hallucinations. Happiness (3-point scale) was assessed with a validated question with higher scores indicating lower levels of happiness. The association between PLE and happiness was assessed by multivariable ordinal logistic regression. Mediation analysis was also performed. Among the 7363 individuals included in the analysis, the prevalence of any PLE increased with decreasing levels of happiness [very happy (2.3%), fairly happy (5.4%), not too happy (14.9%)]. This was also shown in the multivariable analysis adjusted for sociodemographic factors and stressful life events (from very happy to not too happy: OR = 2.41; 95%CI = 1.86-3.12). Mediation analysis showed that anxiety disorders explained the largest proportion of the association (38.8%) followed by depressive episode (28.5%), insomnia (21.9%), disability (16.5%), pain (12.5%), social support (10.0%), and physical health conditions (6.0%). The cross-sectional design limits causal inference. Interventions to identify and address conditions that may have a negative impact on happiness in individuals with PLE may be important to improve their well-being. Copyright © 2017 Elsevier B.V.

Khandaker, Golam M.; Zammit, Stanley; Lewis, Glyn; Jones, Peter B.

2014-01-01

Objective Schizophrenia is associated with atopy and increased inflammatory markers. We report a population-based longitudinal study of the associations between childhood atopic disorders, subsequent serum inflammatory markers, interleukin 6 (IL-6) and C-reactive protein (CRP), and the risk of psychotic experiences (PEs). Method PEs were assessed at age 13 years (n = 6785). Presence of clinician-diagnosed atopic disorders (asthma and eczema) was determined from parent-completed questionnaires at age 10 years (n = 7814). Serum IL-6 and CRP were measured at age 9 years (n = 5076). Logistic regression examined the association between (1) atopy and PEs, (2) inflammatory markers and PEs, and (3) mediating effects of inflammatory markers on the atopy–PEs association. Linear regression examined the association between atopy and inflammatory markers. Age, gender, social class, ethnicity and body mass index were included as potential confounders. Results At age 10 years, about 14% of the sample was reported to have asthma, 12% eczema, and 7% both asthma and eczema. Compared with children with no atopy, risk of PEs at age 13 years was increased for all of these groups; adjusted odds ratios (95% CI) were, respectively, 1.39 (1.10–1.77), 1.33 (1.04–1.69), and 1.44 (1.06–1.94). Atopy was associated with increased serum IL-6 and CRP; however, this did not mediate association between atopy and PEs. Inflammatory markers were not associated with later PEs. Conclusion Childhood atopic disorders increase the risk of psychotic experiences in adolescence. Follow-up of these individuals will be useful to determine the effect of atopy and inflammation on different trajectories of early-life PEs. PMID:24268471

Update on subclinical hyperthyroidism.

Science.gov (United States)

Donangelo, Ines; Braunstein, Glenn D

2011-04-15

Subclinical hyperthyroidism is defined by low or undetectable serum thyroid-stimulating hormone levels, with normal free thyroxine and total or free triiodothyronine levels. It can be caused by increased endogenous production of thyroid hormone (as in Graves disease or toxic nodular goiter), administration of thyroid hormone for treatment of malignant thyroid disease, or unintentional excessive thyroid hormone therapy. The rate of progression to overt hyperthyroidism is higher in persons who have suppressed thyroid-stimulating hormone levels compared with those who have low but detectable levels. Subclinical hyperthyroidism is associated with an increased risk of atrial fibrillation in older adults, and with decreased bone mineral density in postmenopausal women; however, the effectiveness of treatment in preventing these conditions is unknown. There is lesser-quality evidence suggesting an association between subclinical hyperthyroidism and other cardiovascular effects, including increased heart rate and left ventricular mass, and increased bone turnover markers. Possible associations between subclinical hyperthyroidism and quality of life parameters, cognition, and increased mortality rates are controversial. Prospective randomized controlled trials are needed to address the effects of early treatment on potential morbidities to help determine whether screening should be recommended in the asymptomatic general population.

Trauma and adverse childhood experiences (ACE) occur more often in mental illness, including psychosis, than in the general population. Individuals with psychosis (cases) report a higher number and severity (dose) of adversities than healthy controls. While a dose-dependent increase of adversities has been related to more severe psychopathology, the role of type and timing is still insufficiently understood on the exacerbation of positive and negative psychotic symptoms. Moreover, dissociative symptoms were examined as potential mediator between adversities and severity of psychotic symptoms. Exposure to adversities were assessed by interviews in n=180 cases and n=70 controls. In cases, symptom severities were obtained for psychotic symptoms and dissociation. Conditioned random forest regression determined the importance of type and timing of ACE for positive and negative symptom severity, and mediator analyses evaluated the role of dissociative symptoms in the relationship between adversities and psychotic symptoms. Cases experienced substantially more abuse and neglect than controls. Adversities were related in a dose-dependent manner to psychotic disorder. An array of adversities was associated with more severe positive symptoms, while the conditioned random forest regression depicted neglect at age 10 as the most important predictor. Dissociative symptoms mediated the small relation of trauma load in childhood and positive symptoms. The role of trauma and ACE on psychotic symptoms can be specified by neglect during frontocortical development in the exacerbation of positive symptoms. The mediating role of dissociation is restricted to the relation of childhood trauma and positive symptoms. Copyright © 2017 Elsevier B.V. All rights reserved.

Bradley, H K; Shannon, D; Neilson, D R

1989-08-19

By causing poorer horn quality, subclinical laminitis is considered to be a major predisposing cause of other hoof problems, particularly sole ulcers in newly calved heifers. In this study the hind hooves of 136 female Friesian/Holstein cattle aged between four months and two years were examined to discover at what age the signs of subclinical laminitis appeared. Sole haemorrhages were found in the hoof horn of calves as young as five months. The consistent finding of these lesions in heifers of all ages indicated that subclinical laminitis of varying degree was a common condition during the early growing period of young dairy heifers.

Depression with psychotic features afflicts a substantial number of people and has been characterized by significantly greater impairment, higher levels of dysfunctional beliefs, and poorer response to psychopharmacologic and psychosocial interventions than nonpsychotic depression. Those with psychotic depression also experience a host of co-occurring disorders, including posttraumatic stress disorder (PTSD), which is not surprising given the established relationships between trauma exposure and increased rates of psychosis and between PTSD and major depression. To date, there has been very limited research on the psychosocial treatment of psychotic depression; and even less is known about those who also suffer from PTSD. The purpose of this study was to better understand the rates and clinical correlates of psychotic depression in those with PTSD. Clinical and symptom characteristics of 20 individuals with psychotic depression and 46 with nonpsychotic depression, all with PTSD, were compared before receiving cognitive-behavioral therapy for PTSD treatment or treatment as usual. Patients with psychotic depression exhibited significantly higher levels of depression and anxiety, a weaker perceived therapeutic alliance with their case managers, more exposure to traumatic events, and more negative beliefs related to their traumatic experiences, as well as increased levels of maladaptive cognitions about themselves and the world, compared with participants without psychosis. Implications for cognitive-behavioral therapy treatment aimed at dysfunctional thinking for this population are discussed. © 2011 Elsevier Inc. All rights reserved.

Patanè, Salvatore; Marte, Filippo

2010-11-05

Subclinical hyperthyroidism is an increasingly recognized entity that is defined as a normal serum free thyroxine and free triiodothyronine levels with a thyroid-stimulating hormone level suppressed below the normal range and usually undetectable. It has been reported that sub-clinical hyperthyroidism is not associated with CHD or mortality from cardiovascular causes but is sufficient to induce arrhythmias including atrial fibrillation and atrial flutter. Moreover increased factor X activity in patients with subclinical hyperthyroidism represents a potential hypercoagulable state. It has been also reported an acute myocardial infarction with normal coronary arteries associated with iatrogenic hyperthyroidism and with a myocardial bridge too. It has been also reported an acute myocardial infarction without significant coronary stenoses associated with subclinical hyperthyroidism. Furthermore it has been reported that at highly increased hematocrit levels patients may experience hyperviscosity symptoms. We present a case of atrial fibrillation and acute myocardial infarction without significant coronary stenoses associated with subclinical hyperthyroidism and erythrocytosis. Also this case focuses attention on the importance of a correct evaluation of subclinical hyperthyroidism. Copyright © 2008 Elsevier Ireland Ltd. All rights reserved.

"Subclinical" laminitis in dairy cattle.

Science.gov (United States)

Vermunt, J J

1992-12-01

In dairying countries worldwide, the economic importance of lameness in cattle is now recognised. Laminitis is regarded as a major predisposing factor in lameness caused by claw disorders such as white zone lesions, sole ulcer, and heel horn erosion. The existence of subclinical laminitis was first suggested in the late 1970s by Dutch workers describing the symptoms of sole haemorrhages and yellowish-coloured, soft sole horn. In an attempt to clarify some of the confusing and often conflicting terminology, the literature on laminitis is reviewed. Disturbed haemodynamics, in particular repeated or prolonged dilation of arteriovenous anastomoses, have been implicated in the pathogenesis of both equine and bovine laminitis. Some characteristics of the vascular system of the bovine claw which may be of importance in the pathophysiology of the subclinical laminitis syndrome are therefore discussed. Clinical observations suggest that subclinical laminitis is a multifactorial disease. The different factors that are or may be involved in its aetiology vary in complexity and severity according to the management protocol of the animals. The possible involvement of subclinical laminitis in claw lesions is assessed.

Vasu, Devi

2007-01-01

Convulsive therapy and its progeny, electroconvulsive therapy (ECT), were originally used for the treatment of catatonic schizophrenia, and there is little doubt that ECT remains an effective intervention for the treatment of schizophrenia. However, current practice tends to favor the use of ECT in severe or treatment refractory affective disorders, and its use in schizophrenia and other nonaffective (atypical) psychotic disorders has become controversial. Case reports have suggested a role for ECT in two specific atypical psychotic disorders: Cotard's syndrome and cycloid psychosis. In this article, we review the atypical psychotic disorders and report a series of five case examples that signify the role of ECT in atypical psychotic presentations, particularly when the symptoms resemble those found in Cotard's syndrome and cycloid psychosis.

JTC was not associated with level of psychotic symptoms or specifically delusionality across the different groups. Differences between FEP and controls were independent of sex, educational level, cannabis use and IQ. After one year, 47.8% of FEP with JTC at baseline again displayed JTC.JTC in part reflects trait vulnerability to develop disorders with expression of psychotic symptoms.

Impact of online resources and social media on help-seeking behaviour in youth with psychotic symptoms.

2016-10-01

The objective of the study was to explore the content of existing online resources available to information-seeking youth as psychotic symptoms first emerge and determine how these resources may influence initiation of care. Using 18 hypothetical search terms, developed by the Early Treatment Programme (ETP) staff, we searched three of the most popular websites used by the youth (Google, Facebook and Twitter) and extracted the first five hits from each. Sites were categorized into those that encouraged help seeking, those that potentially contribute to treatment delay, those with an undetermined impact and those that were unrelated to treatment. An alarmingly few of the first five hits from the top three online resources encourage potentially psychotic youth to seek professional evaluation. The majority of our search results yielded unmonitored chat forums that lacked a unified message. The remainder promoted stigma, normalized potentially psychotic experiences or were completely unrelated to mental health. We must develop innovative, easy-to-access and youth-focused online and social media experiences that encourage symptomatic youth to seek care. © 2014 Wiley Publishing Asia Pty Ltd.

[Psychotic parricide. Prevention].

Science.gov (United States)

Cornic, F; Olié, J-P

2006-01-01

Parricide is a rare event. In France, statistics indicate that it accounts for 2 to 3% of all homicides. It also represents an appreciable part (up to 30%) of homicides committed by psychotic subjects. Many studies suggest a strong positive correlation between criminality and characterized mental illness. The correlation is better when there is a diagnosis of schizophrenia, an alcohol or drugs consumption and a past personal history of violence. Parricide is a crime mainly committed by males. The most frequent form of parricide is patricide committed by sons. However, considering only psychotic parricides, the number of mothers killed seems is equal or higher to the number of fathers killed. The typical profile of an adult committing parricide could be described as follows: a young single unemployed male, living with his victim, suffering from schizophrenia with comorbidity of alcohol or drug abuse and consumption, who stops his medication, and having a past history of medicolegal behaviours. The parricide act can be divided into three stages; first, the contention of the emergence of parricide ideas; second, the violence and brutality of the act; third, following a transient appeasement suicidal thoughts or attempts are frequently observed. Preventing parricides and homicides committed by psychotic subjects is a great challenge. Only a few studies aim to a better understanding of the underlying motivations of such criminals. According to theses studies, we can point out several warning signals. Psychiatrist should particularly increase their vigilance to persecutive delusions, history of a long lasting illness with history of violence during acute stages, threats against family or friends, suicidal thoughts, failures of help requests and attempt to escape.

Psychotic symptoms are common in children and adolescents and may be early manifestations of liability to severe mental illness (SMI), including schizophrenia. SMI and psychotic symptoms are associated with impairment in executive functions. However, previous studies have not differentiated between 'cold' and 'hot' executive functions. We hypothesized that the propensity for psychotic symptoms is specifically associated with impairment in 'hot' executive functions, such as decision-making in the context of uncertain rewards and losses. In a cohort of 156 youth (mean age 12.5, range 7-24 years) enriched for familial risk of SMI, we measured cold and hot executive functions with the spatial working memory (SWM) task (total errors) and the Cambridge Gambling Task (decision-making), respectively. We assessed psychotic symptoms using the semi-structured Kiddie Schedule for Affective Disorders and Schizophrenia interview, Structured Interview for Prodromal Syndromes, Funny Feelings, and Schizophrenia Proneness Instrument - Child and Youth version. In total 69 (44.23%) youth reported psychotic symptoms on one or more assessments. Cold executive functioning, indexed with SWM errors, was not significantly related to psychotic symptoms [odds ratio (OR) 1.36, 95% confidence interval (CI) 0.85-2.17, p = 0.204). Poor hot executive functioning, indexed as decision-making score, was associated with psychotic symptoms after adjustment for age, sex and familial clustering (OR 2.37, 95% CI 1.25-4.50, p = 0.008). The association between worse hot executive functions and psychotic symptoms remained significant in sensitivity analyses controlling for general cognitive ability and cold executive functions. Impaired hot executive functions may be an indicator of risk and a target for pre-emptive early interventions in youth.

The aim of this study was to measure maximum P wave duration (Pmax) and P wave dispersion (PWD), which can be indicators for the risk of paroxysmal atrial fibrillation when increased, and to reveal their relationship with thyroid hormone levels in patients with endogenous and exogenous subclinical hyperthyroidism. Seventy-one patients with sublinical thyrotoxicosis (34 endogenous, 37 exogenous) and 69 healthy individuals were enrolled in the study. Pmax and minimum P wave duration (Pmin) on electrocardiogram recordings were measured and PWD was calculated as Pmax-Pmin. Pmax (pendogenous subclinical hyperthyroidism compared with the control group. Pmax (pexogenous subclinical thyrotoxicosis compared with the control group. Pmax (p=0.710) and PWD (p=0.127) were not significantly different in patients with endogenous subclinical hyperthyroidism compared with exogenous subclinical hyperthyroid patients. Pmax and PWD negatively associated with TSH in endogenous and exogenous subclinical hyperthyroidism. In the present study, we observed that Pmax and PWD were longer in patients with endogenous and exogenous subclinical hyperthyroidism. Lack of a difference in Pmax and PWD between patients with endogenous and exogenous subclinical hyperthyroidism seems to support the idea that hormone levels rather than the etiology of thyrotoxicosis affect the heart.

Work with dreams in the group analysis represents an important part of the analytical work, with insight into unconscious experiences of the individual dreamer, and his transferrential relations with the therapist, other members of the group, and with the group as a whole. The way dreams are addressed varies from one therapist to another, and in line with that, members of the group have varying frequency of dreams. In groups of psychotic patients dreams are generally rarely discussed and interpreted by the group, with analysis mainly resting on the manifested content. This paper describes a long-term group of psychotic patients which, after sharing the dreams of several members and daydreams of one female patient, their interpretation and reception in the group achieved better cohesion and improved communication and interaction, i.e. created a group matrix. Furthermore, through the content of dreams in the group, traumatic war experiences of several of the group members were opened and discussed, which brought with it recollections of the traumatic life situations of other group members. In expressing a daydream, a female member of the group revealed the background for her behaviour which was earlier interpreted as a negative symptom of the illness.

A growing number of studies demonstrate high rates of subthreshold psychotic experiences, but there is considerable heterogeneity in rates due to study cohort and design factors, obscuring how prevalent psychotic experiences may or may not relate to rare psychotic disorders. In a representative general population sample (n = 4011) in Izmir, Turkey, the full spectrum of expression of psychosis was categorized across 5 groups representing (1) absence of psychosis, (2) subclinical psychotic experiences, (3) low-impact psychotic symptoms, (4) high-impact psychotic symptoms, and (5) full-blown clinical psychotic disorder and analyzed for continuity and discontinuity in relation to (1) other symptom dimensions associated with psychotic disorder and (2) proxies of genetic and nongenetic etiology. Results were tested for linear and extralinear contrasts between clinical and nonclinical and between disorder and nondisorder expression of psychosis. Demographic variables, indexing premorbid social adjustment and socioeconomic status, impacted mostly linearly; proxy variables of genetic loading (more or more severely affected relatives) impacted in a positive extralinear fashion; environmental risk factors sometimes impacted linearly (urbanicity and childhood adversity) and sometimes extralinearly (cannabis), occasioning a disproportional shift in risk at the clinical disorder end of the spectrum. Affective symptoms were associated with a disproportionally higher risk below the disorder threshold, whereas a disproportionally higher risk above the threshold was associated with psychotic symptom load, negative symptoms, disorganization, and visible signs of mental illness. Liability associated with respectively affective and nonaffective symptom domains, in interaction with environmental risks, may operate by impacting differentially over a quasi-continuous extended psychosis phenotype in the population.

We have previously reported an association between childhood abuse and psychotic experiences (PEs) in survey data from South East London. Childhood abuse is related to subsequent adulthood adversity, which could form one pathway to PEs. We aimed to investigate evidence of mediation of the association between childhood abuse and PEs by adverse life events. Data were analysed from the South East London Community Health Study (SELCoH, n = 1698). Estimates of the total effects on PEs of any physical or sexual abuse while growing up were partitioned into direct (i.e. unmediated) and indirect (total and specific) effects, mediated via violent and non-violent life events. There was strong statistical evidence for direct (OR 1.58, 95% CI: 1.19-2.1) and indirect (OR 1.51, 95% CI: 1.32-1.72) effects of childhood abuse on PEs after adjustment for potential confounders, indicating partial mediation of this effect via violent and non-violent life events. An estimated 47% of the total effect of abuse on PEs was mediated via adulthood adverse life events, of which violent life events made up 33% and non-violent life events the remaining 14%. The association between childhood abuse and PEs is partly mediated through the experience of adverse life events in adulthood. There is some evidence that a larger proportion of this effect was mediated through violent life events than non-violent life events.

Language processing abnormalities in adolescents with psychotic-like experiences: An event related potential study.

LENUS (Irish Health Repository)

Murphy, Jennifer

2012-05-01

Language impairments are a well established finding in patients with schizophrenia and in individuals at-risk for psychosis. A growing body of research has revealed shared risk factors between individuals with psychotic-like experiences (PLEs) from the general population and patients with schizophrenia. In particular, adolescents with PLEs have been shown to be at an increased risk for later psychosis. However, to date there has been little information published on electrophysiological correlates of language comprehension in this at-risk group. A 64 channel EEG recorded electrical activity while 37 (16 At-Risk; 21 Controls) participants completed the British Picture Vocabulary Scale (BPVS-II) receptive vocabulary task. The P300 component was examined as a function of language comprehension. The at-risk group were impaired behaviourally on receptive language and were characterised by a reduction in P300 amplitude relative to the control group. The results of this study reveal electrophysiological evidence for receptive language deficits in adolescents with PLEs, suggesting that the earliest neurobiological changes underlying psychosis may be apparent in the adolescent period.

Emerging integrative metacognitive therapies for schizophrenia seek to promote subjective aspects of recovery. Beyond symptom remission, they are concerned with shared meaning-making and intersubjective processes. It is unclear, however, how such therapies should understand and respond to psychotic content that threatens meaning-making in therapeutic contexts. Accordingly, we sought to understand what factors precede and potentially trigger psychotic content within psychotherapy and what aids in resolution and return to meaning-making. Forty-eight transcripts from a single psychotherapy case were analyzed with thematic analysis. Passages of delusional or disorganized content were identified and themes present prior to the emergence and resolution of such material were identified and coded. Themes that preceded the emergence of psychotic content varied across early, middle, and late phases of therapy. Material related to the patient's experience of inadequacy and potential vulnerability, therapist setting boundaries within the therapeutic relationship and making challenges appeared to trigger psychotic content, especially early in treatment. Psychotic content may emerge in session following identifiable antecedents which change over phases of therapy. Attending to psychotic content by assuming a non-hierarchical stance and not dismissing psychotic content may aid in maintaining intersubjectivity and support patient's movements toward recovery in integrative metacognitive therapies.

Postnatal Mother-to-Infant Attachment in Subclinically Depressed Mothers: Dyads at Risk?

Science.gov (United States)

Behrendt, Hannah F; Konrad, Kerstin; Goecke, Tamme W; Fakhrabadi, Roya; Herpertz-Dahlmann, Beate; Firk, Christine

Dyadic interactions between children and depressed mothers have been characterized as less synchronous and with lower maternal sensitivity, fostering an inharmonious, insecure attachment relationship between mother and child. Thus, these children may experience enhanced early life stress and are at higher risk of disturbed socioemotional development. Recently, this association has also been found in women with mild depressive symptoms. However, potential confounding effects of mother's history of own rearing experiences or infant temperament on the link between depressive symptoms and postnatal mother-to-infant attachment have not yet been investigated. Differences in mother-to-infant attachment (e.g. quality of attachment, absence of hostility, and pleasure in interaction) between mothers with and without symptoms of depression 6-8 months postpartum were analyzed in a low-risk community sample (n = 38, 19 per group). Depressive symptomatology was measured with the Beck Depression Inventory (BDI-II) and the Edinburgh Postnatal Depression Scale (EPDS). Depressed mothers indicated mild-to-moderate depressive symptomatology (mean BDI-II 11.26 ± 3.86) but did not fulfill criteria for a major depressive episode and, thus, were referred to as 'subclinically' depressed. Potential confounders, namely maternal history of own rearing experiences and infant temperament, were explored by multivariate AN(C)OVA. Primiparous mothers with subclinical depression differed significantly from healthy control mothers, i.e. showed poorer mother-to-infant attachment and higher infant-related hostility 6-8 months postpartum. As expected, infant temperament and mother's history of own rearing experiences were both associated with mother-to-infant attachment but did not explain the negative effects of subclinical depression on the mother-infant relationship. Given the high prevalence of maternal depression, the current findings give reason for increased concern for the developing mother

Research has shown that young adults with psychotic disorders frequently have problems relating to sexuality, intimacy and relationships. Such problems are often neglected in clinical practice. To perform a study that explores, on the basis of focus groups, how issues such as sexuality, intimacy and relationships can be addressed as part of the treatment of adolescents suffering from a psychotic disorder. We created eight focus groups consisting of clients attending the department of psychotic disorders and caregivers who worked there. The meetings of each focus group were fully transcribed and analysed by means of Nvivo. Clients indicated they wanted to address the topics of sexuality, intimacy and relationships in a group setting. They expressed the wish to have mixed gender groups and decided that in the group discussions the main focus should be on the exchange of personal experiences. In our view, it is desirable that psychiatry should pay more attention to the subject of sexuality. By giving adolescents suffering from psychotic disorders the opportunity to discuss their experiences, problems and feelings of insecurity in a group setting and in a low-threshold environment, psychiatrists can greatly improve the quality of care that they provide for their patients.

Deficits in working memory (WM) and emotion processing are prominent impairments in psychotic disorders, and have been linked to reduced quality of life and real-world functioning. Translation of knowledge regarding the neural circuitry implementing these deficits into improved diagnosis and targeted treatments has been slow, possibly because of categorical definitions of disorders. Using the dimensional Research Domain Criteria (RDoC) framework, we investigated the clinical and practical utility of transdiagnostic behavioral and neural measures of emotion-related WM disruption across psychotic disorders. Behavioral and functional MRI data were recorded while 53 participants with psychotic disorders and 29 participants with no history of psychosis performed a modified n-back task with fear and neutral distractors. Hierarchical regression analyses showed that psychotic symptoms entered after diagnosis accounted for unique variance in fear versus neutral accuracy and activation in the ventrolateral, dorsolateral, and dorsomedial prefrontal cortex, but diagnostic group entered after psychotic symptoms did not. These results remained even after controlling for negative symptoms, disorganized symptoms, and dysphoria. Finally, worse accuracy and greater prefrontal activity were associated with poorer social functioning and unemployment across diagnostic groups. Present results support the transdiagnostic nature of behavioral and neuroimaging measures of emotion-related WM disruption as they relate to psychotic symptoms, irrespective of diagnosis. They also provide support for the practical utility of these markers in explaining real-world functioning. Overall, these results elucidate key aspects of the RDoC construct of WM maintenance by clarifying its transdiagnostic importance and clinical utility in psychotic disorders.

Background For the purpose of diagnosis, psychopathology can be represented as categories of mental disorder, symptom dimensions or symptom networks. Also, psychopathology can be assessed at different levels of temporal resolution (monthly episodes, daily fluctuating symptoms, momentary fluctuating mental states). We tested the diagnostic value, in terms of prediction of treatment needs, of the combination of symptom networks and momentary assessment level. Method Fifty-seven patients with a psychotic disorder participated in an ESM study, capturing psychotic experiences, emotions and circumstances at 10 semi-random moments in the flow of daily life over a period of 6 days. Symptoms were assessed by interview with the Positive and Negative Syndrome Scale (PANSS); treatment needs were assessed using the Camberwell Assessment of Need (CAN). Results Psychotic symptoms assessed with the PANSS (Clinical Psychotic Symptoms) were strongly associated with psychotic experiences assessed with ESM (Momentary Psychotic Experiences). However, the degree to which Momentary Psychotic Experiences manifested as Clinical Psychotic Symptoms was determined by level of momentary negative affect (higher levels increasing probability of Momentary Psychotic Experiences manifesting as Clinical Psychotic Symptoms), momentary positive affect (higher levels decreasing probability of Clinical Psychotic Symptoms), greater persistence of Momentary Psychotic Experiences (persistence predicting increased probability of Clinical Psychotic Symptoms) and momentary environmental stress associated with events and activities (higher levels increasing probability of Clinical Psychotic Symptoms). Similarly, the degree to which momentary visual or auditory hallucinations manifested as Clinical Psychotic Symptoms was strongly contingent on the level of accompanying momentary paranoid delusional ideation. Momentary Psychotic Experiences were associated with CAN unmet treatment needs, over and above PANSS

Full Text Available Several studies showed the close relationship between Rheumatoid Arthritis (RA and cerebro-cardiovascular events (CVEs and subclinical atherosclerosis. In this study, we investigated the occurrence of CVEs and subclinical atherosclerosis during the course of RA and we evaluated the possible role of both traditional cardiovascular (CV and disease related risk factors to predict the occurrence of new CVEs and the onset of subclinical atherosclerosis.We designed a single centre, bias-adjusted, prospective, observational study to investigate, in a homogeneous subset of RA patients, the occurrence of new onset of CVEs and subclinical atherosclerosis. Statistical analyses were performed to evaluate the role of traditional CV and disease-related risk factors to predict the occurrence of new CVEs and subclinical atherosclerosis.We enrolled 347 RA patients prospectively followed for 12 months. An increased percentage of patients experienced CVEs, developed subclinical atherosclerosis and was affected by systemic arterial hypertension (SAH, type 2 diabetes mellitus and metabolic syndrome (MS, at the end of follow up. Our analysis showed that the insurgence of both SAH and MS, during the follow up, the older age, the CVE familiarity and the lack of clinical response, were associated with a significantly increased risk to experience CVEs and to develop subclinical atherosclerosis.Our study quantifies the increased expected risk for CVEs in a cohort of RA patients prospectively followed for 1 year. The occurrence of both new CVEs and subclinical atherosclerosis in RA patients may be explained by inflammatory burden as well as traditional CV risk factors.

Does the concept of "sensitization" provide a plausible mechanism for the putative link between the environment and schizophrenia?

Science.gov (United States)

Collip, Dina; Myin-Germeys, Inez; Van Os, Jim

2008-03-01

Previous evidence reviewed in Schizophrenia Bulletin suggests the importance of a range of different environmental factors in the development of psychotic illness. It is unlikely, however, that the diversity of environmental influences associated with schizophrenia can be linked to as many different underlying mechanisms. There is evidence that environmental exposures may induce, in interaction with (epi)genetic factors, psychological or physiological alterations that can be traced to a final common pathway of cognitive biases and/or altered dopamine neurotransmission, broadly referred to as "sensitization," facilitating the onset and persistence of psychotic symptoms. At the population level, the behavioral phenotype for sensitization may be examined by quantifying, in populations exposed to environmental risk factors associated with stress or dopamine-agonist drugs, (1) the increased rate of persistence (indicating lasting sensitization) of normally transient developmental expressions of subclinical psychotic experiences and (2) the subsequent increased rate of transition to clinical psychotic disorder.

Management of Subclinical Hyperthyroidism

Santos Palacios, Silvia; Pascual-Corrales, Eider; Galofre, Juan Carlos

2012-01-01

The ideal approach for adequate management of subclinical hyperthyroidism (low levels of thyroid-stimulating hormone [TSH] and normal thyroid hormone level) is a matter of intense debate among endocrinologists. The prevalence of low serum TSH levels ranges between 0.5% in children and 15% in the elderly population. Mild subclinical hyperthyroidism is more common than severe subclinical hyperthyroidism. Transient suppression of TSH secretion may occur because of several reasons; thus, corroboration of results from different assessments is essential in such cases. During differential diagnosis of hyperthyroidism, pituitary or hypothalamic disease, euthyroid sick syndrome, and drug-mediated suppression of TSH must be ruled out. A low plasma TSH value is also typically seen in the first trimester of gestation. Factitial or iatrogenic TSH inhibition caused by excessive intake of levothyroxine should be excluded by checking the patient’s medication history. If these nonthyroidal causes are ruled out during differential diagnosis, either transient or long-term endogenous thyroid hormone excess, usually caused by Graves’ disease or nodular goiter, should be considered as the cause of low circulating TSH levels. We recommend the following 6-step process for the assessment and treatment of this common hormonal disorder: 1) confirmation, 2) evaluation of severity, 3) investigation of the cause, 4) assessment of potential complications, 5) evaluation of the necessity of treatment, and 6) if necessary, selection of the most appropriate treatment. In conclusion, management of subclinical hyperthyroidism merits careful monitoring through regular assessment of thyroid function. Treatment is mandatory in older patients (> 65 years) or in presence of comorbidities (such as osteoporosis and atrial fibrillation). PMID:23843809

Although schizophrenia can be treated, most patients still experience inevitable psychotic episodes from time to time. Precautious actions can be taken if the next onset can be predicted. However, sufficient information is always lacking in the clinical scenario. A possible solution is to use the virtual data generated from limited of original data. Data construction method (DCM) has been shown to generate the virtual felt earthquake data effectively and used in the prediction of further events. Here we investigated the performance of DCM in deriving the membership functions and discrete-event simulations (DES) in predicting the period embracing the initiation and termination time-points of the next psychotic episode of 35 individual schizophrenic patients. The results showed that 21 subjects had a success of simulations (RSS) ≥70%. Further analysis demonstrated that the co-morbidity of coronary heart diseases (CHD), risks of CHD, and the frequency of previous psychotic episodes increased the RSS.

Full Text Available The effect of subclinical thyroid dysfunction on vascular atherosclerosis remains uncertain. The objective of this study was to elucidate the association between sustained subclinical thyroid dysfunction and carotid plaques, which are an early surrogate marker of systemic atherosclerosis.The study included 21,342 adults with consistent thyroid hormonal status on serial thyroid function tests (TFTs and carotid artery duplex ultrasonography at a health screening center between 2007 and 2014. The effect of subclinical thyroid dysfunction on baseline carotid plaques and newly developed carotid plaques during 5-year follow-up was determined by logistic regression analyses and GEE (Generalized Estimating Equations, respectively.Carotid plaques were more common in the subclinical hypothyroidism (55.6% than the euthyroidism (47.8% at baseline. However, in multivariable analysis, thyroid status was not a significant risk for the carotid plaques at baseline. Instead, traditional cardiovascular risk factors, such as age (P <0.001, systolic blood pressure (P = 0.023, fasting blood glucose (P = 0.030, and creatinine (P = 0.012 were associated with baseline carotid plaques in subclinical hypothyroidism. In longitudinal analyses of subjects who were followed up for more than 5 years, there was no significant difference in the cumulative incidence of new carotid plaques according to time between subjects with subclinical hypothyroidism and those with euthyroidism (P = 0.392.Sustained subclinical thyroid dysfunction did not affect the baseline or development of carotid plaques in healthy individuals.

Full Text Available Abstract Background Psychotic depression is a clinical subtype of major depressive disorder. A number of clinical studies have demonstrated the efficacy of the combination of an antidepressant (for example, a tricyclic antidepressant or selective serotonin reuptake inhibitor (SSRI and an atypical antipsychotic or electroconvulsive therapy in treating psychotic depression. In some cases, the clinician or patient may prefer to avoid antipsychotic drugs altogether because of the risk of extrapyramidal side effects (EPS in patients with psychotic depression treated with these drugs. Methods We report five cases where fluvoxamine monotherapy was effective in the patients with psychotic depression. Results The scores on the Hamilton Depression (HAM-D scale and the Brief Psychiatric Rating Scale (BPRS in the five patients with psychotic depression were reduced after fluvoxamine monotherapy. Conclusion Doctors should consider fluvoxamine monotherapy as an alternative approach in treating psychotic depression because it avoids the risk of EPS from antipsychotic drugs.

Psychotic-spectrum symptoms are linked to trauma, substance/alcohol use (SAU), criminality/violence and poor functional outcomes, supporting the need for early detection in vulnerable populations. To better understand high-risk girls' mental health, we assessed: (1) psychotic-spectrum symptoms; (2) cumulative trauma, adversity and loss exposures (C-TALE) and adversity-indicators (symptoms, maladaptive coping, stressor-reactivity); and SAU risk-factors; and (3) relationships among psychotic-spectrum symptoms, adversity-indicators and SAU risk-factors. We administered the Structured Clinical Interviews for Psychotic Spectrum, and Trauma and Loss Spectrum to 158 adolescent delinquent girls. Girls' psychotic-spectrum profiles were similar to previously reported adult psychotic patients and characterized by typical symptoms (hallucinations/delusions, reported largely SAU-independent), interpersonal sensitivity, schizoid traits and paranoia (over-interpretation, anger over-reactivity, hypervigilance). Auditory/visual hallucinations (55.7%), delusions (92.4%), ideas of reference (96.8%) and adversity (90.0% ≥10/24 C-TALE-types) were common. Mean loss (4) and trauma (8) onset-age occurred before SAU-onset (12). Significant positive correlations were found among psychotic-spectrum symptoms, stressor-reactivity, C-TALE, adversity-indicators; and number of SAU-types; and a negative correlation occurred between psychotic-spectrum symptoms and earlier alcohol use onset. After controlling for number of SAU-types, stressor-reactivity and adversity-related numbing individually had the largest associations with total psychotic-spectrum symptoms (b = 2.6-4.3). Girls averaged more than 4 maladaptive coping strategies (e.g., 24.8% attempted suicide) in response to adversity, amplifying potential health-disparities. No racial/ethnic differences emerged on psychotic-spectrum symptoms. This symptom constellation during adolescence likely interferes with social and academic

Magnetic resonance imaging scans of the brain on first-episode patients and on healthy controls. Patients with schizophrenia had a smaller left frontal grey matter volume than the other three groups. Patients with psychotic depression had larger ventricular and posterior sulcal cerebrospinal fluid (CSF) volumes than controls. Patients with depression had larger white matter volumes than the other patients. Left frontal lobe, especially its grey matter volume, seems to be specifically reduced in first-episode schizophrenia. Enlarged cerebral ventricles and sulcal CSF volumes are prevalent in psychotic depression. Preserved or expanded white matter is typical of non-psychotic depression.

The aim of this study was to explore mental health staffs' experiences of assisting people with psychotic disorders to implement lifestyle changes in an effort to prevent metabolic syndrome. Qualitative interviews were conducted with 12 health care professionals working in psychosis outpatient care in Sweden. Data were analysed using a qualitative content analysis. The results illustrate that implementation of lifestyle changes among people with psychotic disorders was experienced as difficult, but possible. The greatest obstacles experienced in this work were difficulties due to the reduction of cognitive functions associated with the disease. Guidelines available to staff in order to help them identify and prevent physical health problems in the group were not always followed and the content was not always relevant. Staff further described feelings of uncertainty about having to motivate people to take anti-psychotic medication while simultaneously being aware of the risks of metabolic deviations. Nursing interventions focusing on organising daily routines before conducting a more active prevention of metabolic syndrome, including information and practical support, were experienced as necessary. The importance of healthy eating and physical activity needs to be communicated in such a way that it is adjusted to the person's cognitive ability, and should be repeated over time, both verbally and in writing. Such efforts, in combination with empathic and seriously committed community-based social support, were experienced as having the best effect over time. Permanent lifestyle changes were experienced as having to be carried out on the patient's terms and in his or her home environment.

To determine whether alterations in pulmonary function takes place in subclinical hypothyroidism by examining the diffusion lung capacity and muscle strength of such patients. This is a descriptive study conducted in 2009 at Haseki Training and Research Hospital, Istanbul, Turkey. Hundred and twenty-six patients with subclinical hypothyroidism and 58 age and sex matched individuals were recruited. Simple spirometry tests were performed, and pulmonary diffusion capacity (DLco) and muscle strength were measured. ScH patients showed a significant reduciton of the following pulmonary function tests (% predicted value) as compared with control subjects: FVC, FEV1, FEV1%, FEF25-75, FEF25-75%, DLco, DLco/VA, Pimax, Pimax% and Pemax%. These data indicate that pulmonary functions are effected in subclinical hypothyrodism. Therefore patients with or who are at high risk of having subclinical hypothyroidism, should be subjected to evaluation of pulmonary functions with simple spirometry.

Lifetime prevalence of psychotic disorders varies widely across studies. Epidemiological surveys have rarely examined prevalences of specific psychotic disorders other than schizophrenia, and the majority used a single-phase design without employing clinical reappraisal interview for diagnostic verification. The current study investigated lifetime prevalence, correlates and service utilization of schizophrenia-spectrum, affective, and other non-affective psychotic disorders in a representative sample of community-dwelling Chinese adult population aged 16-75 years (N = 5719) based on a territory-wide, population-based household survey for mental disorders in Hong Kong. The survey adopted a 2-phase design comprising first-phase psychosis screening and second-phase diagnostic verification incorporating clinical information from psychiatrist-administered semi-structured interview and medical record review to ascertain DSM-IV lifetime diagnosis for psychotic disorders. Data on sociodemographics, psychosocial characteristics and service utilization were collected. Our results showed that lifetime prevalence was 2.47% for psychotic disorder overall, 1.25% for schizophrenia, 0.15% for delusional disorder, 0.38% for psychotic disorder not otherwise specified, 0.31% for bipolar disorder with psychosis, and 0.33% for depressive disorder with psychosis. Schizophrenia-spectrum disorder was associated with family history of psychosis, cigarette smoking and variables indicating socioeconomic disadvantage. Victimization experiences were significantly related to affective psychoses and other non-affective psychoses. Around 80% of participants with any psychotic disorder sought some kind of professional help for mental health problems in the past year. Using comprehensive diagnostic assessment involving interview and record data, our results indicate that approximately 2.5% of Chinese adult population had lifetime psychotic disorder which represents a major public health concern. �

The fragmented self: imbalance between intrinsic and extrinsic self-networks in psychotic disorders.

Ebisch, Sjoerd J H; Aleman, André

2016-08-01

Self-disturbances are among the core features of schizophrenia and related psychotic disorders. The basic structure of the self could depend on the balance between intrinsic and extrinsic self-processing. We discuss studies on self-related processing in psychotic disorders that provide converging evidence for disrupted communication between neural networks subserving the so-called intrinsic self and extrinsic self. This disruption might be mainly caused by impaired integrity of key brain hubs. The intrinsic self has been associated with cortical midline structures involved in self-referential processing, autobiographical memory, and emotional evaluation. Additionally, we highlight central aspects of the extrinsic self in its interaction with the environment using sensorimotor networks, including self-experience in sensation and actions. A deficient relationship between these self-aspects because of disrupted between-network interactions offers a framework to explain core clinical features of psychotic disorders. In particular, we show how relative isolation and reduced modularity of networks subserving intrinsic and extrinsic self-processing might trigger the emergence of hallucinations and delusions, and why patients with psychosis typically have difficulties with self-other relationships and do not recognise mental problems.

2015-01-01

Context: Both subclinical thyroid dysfunction and frailty are common among older individuals, but data on the relationship between these 2 conditions are conflicting. Objective: The purpose of this study was to assess the cross-sectional and prospective associations between subclinical thyroid dysfunction and frailty and the 5 frailty subdomains (sarcopenia, weakness, slowness, exhaustion, and low activity). Setting and Design: The Osteoporotic Fractures in Men Study is a prospective cohort study. Participants: Men older than 65 years (n = 1455) were classified into 3 groups of thyroid status: subclinical hyperthyroidism (n = 26, 1.8%), subclinical hypothyroidism (n = 102, 7.0%), and euthyroidism (n = 1327, 91.2%). Main Outcome Measures: Frailty was defined using a slightly modified Cardiovascular Health Study Index: men with 3 or more criteria were considered frail, men with 1 to 2 criteria were considered intermediately frail, and men with no criteria were considered robust. We assessed the cross-sectional relationship between baseline thyroid function and the 3 categories of frailty status (robust/intermediate/frail) as well as the prospective association between baseline thyroid function and subsequent frailty status and mortality after a 5-year follow-up. Results: At baseline, compared with euthyroid participants, men with subclinical hyperthyroidism had an increased likelihood of greater frailty status (adjusted odds ratio, 2.48; 95% confidence interval, 1.15–5.34), particularly among men aged hyperthyroidism were not consistently associated with overall frailty status or frailty components. Conclusion: Among community-dwelling older men, subclinical hyperthyroidism, but not subclinical hypothyroidism, is associated with increased odds of prevalent but not incident frailty.

Subclinical Cushing's syndrome: current concepts and trends.

Science.gov (United States)

Zografos, George N; Perysinakis, Iraklis; Vassilatou, Evangeline

2014-01-01

Clinically inapparent adrenal masses which are incidentally detected have become a common problem in everyday practice. Approximately 5-20% of adrenal incidentalomas present subclinical cortisol hypersecretion which is characterized by subtle alterations of the hypothalamic-pituitary-adrenal axis due to adrenal autonomy. This disorder has been described as subclinical Cushing's syndrome, since there is no typical clinical phenotype. The diagnosis of subclinical Cushing's syndrome is based on biochemical evaluation; however, there is still no consensus for the biochemical diagnostic criteria. An abnormal 1mg dexamethasone suppression test (DST) as initial screening test in combination with at least one other abnormal test of the hypothalamic-pituitary-adrenal axis has been advocated by most experts for the diagnosis of subclinical Cushing's syndrome. DST is the main method of establishing the diagnosis, while there is inhomogeneity of the information that other tests provide. Arterial hypertension, diabetes mellitus type 2 or impaired glucose tolerance, central obesity, osteoporosis/vertebral fractures and dyslipidemia are considered as detrimental effects of chronic subtle cortisol excess, although there is no proven causal relationship between subclinical cortisol hypersecretion and these morbidities. Therapeutic strategies include careful observation along with medical treatment of morbidities potentially related to subtle cortisol hypersecretion versus laparoscopic adrenalectomy. The optimal management of patients with subclinical Cushing's syndrome is not yet defined. The conservative approach is appropriate for the majority of these patients; however, the duration of follow-up and the frequency of periodical evaluation still remain open issues. Surgical resection may be beneficial for patients with hypertension, diabetes mellitus type 2 or abnormal glucose tolerance and obesity.

Full Text Available The subclinical form of visceral leishmaniasis (VL shows nonspecific clinical manifestations, with difficulties being frequently met in its clinical characterization and diagnostic confirmation. Thus, the objective of the present study was to define the clinical-laboratory profile of this clinical form. A cohort study was conducted in the state of Maranhão, Brazil, from January/1998 to December/2000, with monthly follow-up of 784 children aged 0-5 years. Based on the clinical-laboratory parameters reported in the literature, four categories were established, with the children being classified (according to their clinical-evolutive behavior as asymptomatic (N = 144, as having the subclinical form (N = 33 or the acute form (N = 12 or as subjects "without VL" (N = 595. Multiple discriminant analysis demonstrated that the combination of fever, hepatomegaly, hyperglobulinemia, and increased blood sedimentation rate (BSR can predict the subclinical form of VL as long as it is not associated with splenomegaly or leukopenia. Subjects with the subclinical form did not show prolonged or intermittent evolution or progression to the acute form of VL. Subclinical cases have a profile differing from the remaining clinical forms of VL, being best characterized by the combination of fever, hepatomegaly, hyperglobulinemia, and increased BSR.

Early social and cognitive alterations in psychotic disorder, associated with familial liability and environmental exposures, may contribute to lower than expected educational achievement. The aims of the present study were to investigate (1) how differences in educational level between parents and their children vary across patients, their healthy siblings, and healthy controls (effect familial liability), and across two environmental risk factors for psychotic disorder: childhood trauma and childhood urban exposure (effect environment) and (2) to what degree the association between familial liability and educational differential was moderated by the environmental exposures. Patients with a diagnosis of non-affective psychotic disorder (n = 629), 552 non-psychotic siblings and 326 healthy controls from the Netherlands and Belgium were studied. Participants reported their highest level of education and that of their parents. Childhood trauma was assessed with the Dutch version of the Childhood Trauma Questionnaire-Short Form. Urban exposure, expressed as population density, was rated across five levels. Overall, participants had a higher level of education than their parents. This difference was significantly reduced in the patient group, and the healthy siblings displayed intergenerational differences that were in between those of controls and patients. Higher levels of childhood urban exposure were also associated with a smaller intergenerational educational differential. There was no evidence for differential sensitivity to childhood trauma and childhood urbanicity across the three groups. Intergenerational difference in educational achievements is decreased in patients with psychotic disorder and to a lesser extent in siblings of patients with psychotic disorder, and across higher levels of childhood urban exposure. More research is required to better understand the dynamics between early social and cognitive alterations in those at risk in relation to progress

We investigated the relationship between internalized stigma of mental illness at baseline and depressive and psychotic symptoms 3 and 6 months later, controlling for baseline symptoms. Data on homeless veterans with severe mental illness (SMI) were provided by the Northeast Program Evaluation Center (NEPEC) Special Needs-Chronic Mental Illness (SN-CMI) study (Kasprow and Rosenheck, 2008). The study used the Internalized Stigma of Mental Illness (ISMI) scale to measure internalized stigma at baseline and the Symptom Checklist-90-R (SCL-90-R) to measure depressive and psychotic symptoms at baseline and 3 and 6 month follow-ups. Higher levels of internalized stigma were associated with greater levels of depressive and psychotic symptoms 3 and 6 months later, even controlling for symptoms at baseline. Alienation and Discrimination Experience were the subscales most strongly associated with symptoms. Exploratory analyses of individual items yielded further insight into characteristics of potentially successful interventions that could be studied. Overall, our findings show that homeless veterans with SMI experiencing higher levels of internalized stigma are likely to experience more depression and psychosis over time. This quasi-experimental study replicates and extends findings of other studies and has implications for future controlled research into the potential long-term effects of anti-stigma interventions on mental health recovery.

Epidemiological studies in the Netherlands have reported an excessive gender gap in the risk for non-affective psychotic disorder (NAPD) among immigrants from Morocco with a higher risk elevation in males compared to females. We examined the consistency of these findings and their generalizability to immigrants from the Maghreb (Mauritania, Morocco, Algeria, Tunisia and Libya) in other European countries. Systematic review and meta-analysis. Medline, PsychINFO and EMBASE databases were searched for publications in the period from January 1970 to April 2014. We included incidence and prevalence studies of non-affective psychotic disorder (NAPD) among migrants from the Maghreb in Europe and studies of subclinical psychotic symptoms (SPS) in representative samples. A meta-analysis was performed on the subgroup of incidence studies. Five incidence and three prevalence studies of NAPD, and two prevalence studies of SPS, conducted in the Netherlands (n=7), Belgium (n=1), France (n=1) and Italy (n=1) met our inclusion criteria. Across all research designs, the risks of NAPD and SPS were consistently increased among male, not female immigrants from the Maghreb. The meta-analysis of incidence studies of NAPD yielded male-to-female risk ratios of 5.1 [95 % confidence interval (CI) 3.1-8.4] for migrants from the Maghreb, 2.0 (95 % CI 1.6-2.5) for other migrant groups, and 1.8 (95 % CI 1.3-2.5) for non-migrant Europeans. The marked gender gap in psychosis risk among migrants from the Maghreb appears a consistent finding, foremost among the Moroccan-Dutch. The small number of studies limits the strength of conclusions that can be drawn about countries other than the Netherlands. Achievement-expectation mismatch, social marginalization and an increased prevalence of illicit drug use are possible explanations.

Objective While it is now recognized that psychotic experiences (PEs) are associated with an increased risk of later mental disorders, we lack a detailed understanding of the reciprocal time-lagged relationships between first onsets of PEs and mental disorders. Methods The WHO World Mental Health (WMH) surveys assessed lifetime prevalence and age-of-onset of PEs and 21 common DSM-IV mental disorders among 31,261 adult respondents from 18 countries. Results Temporally primary PEs were significantly associated with subsequent first onset of 8 of the 21 mental disorders (major depressive disorder, bipolar disorder, generalized anxiety disorder, social phobia, post-traumatic stress disorder, adult separation anxiety disorder, bulimia nervosa, alcohol abuse), with ORs (95%CI) ranging from 1.3 (1.2–1.5; major depressive disorder) to 2.0 (1.5–2.6; bipolar disorder). In contrast, 18 of 21 primary mental disorders were significantly associated with subsequent first onset of PEs, with ORs (95% CI) ranging from 1.5 (1.0–2.1; childhood separation anxiety disorder) to 2.8 (1.0–7.8; anorexia nervosa). Conclusions While temporally primary PEs are associated with an elevated risk of several subsequent mental disorders, we found that most mental disorder are associated with an elevated risk of subsequent PEs. Further investigation of the underlying factors accounting for these time-order relationships might shed light on the etiology of PEs. PMID:26988628

The use of olanzapine in Huntington disease accompanied by psychotic symptoms

Full Text Available Huntington's disease is an autosomal dominant neurodegenerative disease. The disease begins between the ages of 30-50, including motor symptoms, psychiatric symptoms and is characterized by progressive dementia. Common psychiatric disorders of Huntington’s disease include mood and anxiety disorders, behavior and personality changes. Psychosis is relatively rare. Here, a patient is present, who has Huntington’s disease, which is associated with psychotic symptoms. 61-year-old male patient who were followed for Huntington disease for 25 years was admitted for complaints of thinking of poisoning and refuse to eat something. Patient was started on olanzapine at dose of 5 mg/day. In follow up psychotic symptoms disappeared. Emerging psychotic symptoms in Huntington disease is created a need for antipsychotic treatment. Atypical antipsychotic agents should be preferred in the treatment and as in the case olanzapine may be used as a treatment option should be kept in mind to control both involuntary movements and psychotic symptoms in Huntington's disease with psychotic features.

Subclinical hyperthyroidism appears to be a common disorder. It may be caused by exogenous or endogenous factors: excessive TSH suppressive therapy with L-thyroxine (L-T4) for benign thyroid nodular disease, differentiated thyroid cancer, or hormone over-replacement in patients with hypothyroidism are the most frequent causes. Consistent evidence indicates that 'subclinical' hyperthyroidism reduces the quality of life, affecting both the psycho and somatic components of well-being, and produces relevant signs and symptoms of excessive thyroid hormone action, often mimicking adrenergic overactivity. Subclinical hyperthyroidism exerts many significant effects on the cardiovascular system; it is usually associated with a higher heart rate and a higher risk of supraventricular arrhythmias, and with an increased left ventricular mass, often accompanied by an impaired diastolic function and sometimes by a reduced systolic performance on effort and decreased exercise tolerance. It is well known that these abnormalities usually precede the onset of a more severe cardiovascular disease, thus potentially contributing to the increased cardiovascular morbidity and mortality observed in these patients. In addition, it is becoming increasingly apparent that subclinical hyperthyroidism may accelerate the development of osteoporosis and hence increased bone vulnerability to trauma, particularly in postmenopausal women with a pre-existing predisposition. Subclinical hyperthyroidism and its related clinical manifestations are reversible and may be prevented by timely treatment.

Psychotic symptoms that frequently occur in combat-related posttraumatic stress disorder (PTSD) complicate its pharmacotherapy. We hypothesized that war veterans with psychotic PTSD, resistant to prior antidepressant treatment, would respond well to 6 weeks of treatment with the atypical antipsychotic risperidone, given as a monotherapy. Twenty-six male war veterans with psychotic PTSD (DSM-IV) completed the 6-week inpatient treatment with risperidone (2-4 mg/day) during the period from November 1999 through December 2002. The primary outcome measure was change from baseline to endpoint (6 weeks) in Positive and Negative Syndrome Scale (PANSS) total and subscale scores. Secondary outcome measures were changes in PTSD Interview (PTSD-I) and Clinical Global Impressions-Severity of Illness scale (CGI-S) total and subscale scores. Clinical improvement was assessed by CGI-S, CGI-Improvement scale, and Patient Global Impression of Improvement scale, while adverse events were recorded by Drug-Induced Extrapyramidal Symptoms Scale. Treatment with risperidone for either 3 or 6 weeks in an open trial significantly reduced total and subscales scores on the PANSS and on the PTSD-I and CGI-S when compared to baseline scores in patients with psychotic PTSD. Our preliminary data from the open trial indicate that risperidone decreased most of the psychotic and PTSD symptoms. Psychotic PTSD patients, unresponsive to antidepressant treatment, improved significantly after treatment for either 3 or 6 weeks with risperidone.

Sibutramine is a weight loss agent recently withdrawn from the European market due to cardiovascular risk concerns. It was used for long-term obesity treatment. Zolpidem is a short acting hypnotic agent commonly used in the treatment of insomnia. A number of case reports describing psychotic reaction to sibutramine were reported in the literature. We present a case of a 61-year-old Caucasian woman who developed two psychotic episodes related to sibutramine treatment. The second psychotic episode was complicated with complex behaviours after zolpidem use due to insomnia. Sibutramine and zolpidem discontinuation resulted in rapid resolution of psychotic symptoms. This case suggests a possibility of incidence of psychotic symptoms and complex behaviour disturbances in patients prescribed sibutramine or other monoaminergic reuptake inhibitors.

Comorbidity of psychosis and substance abuse has gained increased attention for some time. However, pharmacological treatment for opioid dependence among psychotic patients is seldom described. We present the treatment of four opioid dependent psychotic patients with methadone and antipsychotic medication. Three of the four patients had initially a period of increased psychotic symptoms, but all four patients have shown marked improvement following the introduction of methadone. Compliance with treatment has increased, they have had enduring non-psychotic periods and a markedly reduced use of illegal substances. The results should obviously be interpreted with caution, given the small number of subjects. Further research is therefore important.

Endogenous subclinical hyperthyroidism and cardiovascular system: time to reconsider?

Patanè, Salvatore; Marte, Filippo; Sturiale, Mauro

2011-05-19

Subclinical hyperthyroidism is an increasingly recognized entity that is defined as a normal serum free thyroxine and free triiodothyronine levels with a thyroid-stimulating hormone level suppressed below the normal range and usually undetectable. Exogenous sublinical hyperthyroidism is a thyroid metabolic state caused by L-thyroxine administration. Endogenous subclinical hyperthyroidism is a thyroid metabolic state in patients with autonomously functioning thyroid nodule or multinodular goiter, various forms of thyroiditis, in areas with endemic goiter and particularly in elderly subjects. Endogenous subclinical hyperthyroidism is currently the subject of numerous studies and it yet remains controversial particularly as it relates to its treatment and to cardiovascular impact nevertheless established effects have been demonstrated. Recently, acute myocardial infarction without significant coronary stenoses and recurrent acute pulmonary embolism have been reported associated with subclinical hyperthyroidism without L-thyroxine administration. So, it is very important to recognize and to treat promptly also endogenous subclinical hyperthyroidism. Copyright © 2009 Elsevier Ireland Ltd. All rights reserved.

To assess the natural history and progression of subclinical hypothyroidism and to study factors which help predict evolution of subclinical hypothyroidism into overt hypothyroidism. Longitudinal study in 40 children (2-16 yrs) presenting with subclinical hypothyroidism in a tertiary care unit in Chennai, India. Patients showing evidence of overt hypothyroidism or thyroid stimulating hormone ≥15 mIU/mL during follow-up were started on thyroxine. Others were followed up with 3-monthly thyroid function tests up to one year. At the end of our study period 3 (7.5%) were overtly hypothyroid, 16 (40%) remained as subclinical hypothyroid, and 21 (52.5%) became euthyroid. Evidence of auto- immunity at baseline was a significant (Phypothyroidism. Subclinical hypothyroidism in children, with thyroid stimulating hormone upto 15 mIU/L and irrespective of thyroid autoimmunity, needs only periodic clinical and biochemical follow up. Thyroid autoimmunity may point to an increased probability of progression to overt hypothyroidism.

Sleep, circadian rhythms, and schizophrenia: where we are and where we need to go.

2018-05-01

The review is designed to give an overview of the latest developments in research exploring the relationship between sleep and psychosis, with particular attention paid to the evidence for a causal relationship between the two. The most interesting avenues currently in pursuit are focused upon sleep spindle deficits which may hallmark an endophenotype; explorations of the continuum of psychotic experiences, and experimental manipulations to explore the evidence for bidirectional causality; inflammatory markers, psychosis and sleep disturbances and finally, treatment approaches for sleep in psychosis and the subsequent impact on positive experiences. Globally, large surveys and tightly controlled sleep deprivation or manipulation experiments provide good evidence for a cause-and-effect relationship between sleep and subclinical psychotic experiences. The evidence for cause-and-effect using a interventionist-causal model is more ambiguous; it would appear treating insomnia improves psychotic experiences in an insomnia cohort but not in a cohort with schizophrenia. This advocates the necessity for mechanism-driven research with dimensional approaches and in depth phenotyping of circadian clock-driven processes and sleep regulating functions. Such an approach would lead to greater insight into the dynamics of sleep changes in healthy and acute psychosis brain states.

Remedy often involves corrective metaphysical intervention, either exclusively or in addition to other methods, such as 'western Medicine'. This 'rule' is said to fit mental illness more than any other type of illness, although there is a lack of empirical data on the subject. This study is aimed at identifying elements of a Yoruba world view, and factors relevant to the perception and treatment of psychotic illness. 500 Yorubas in Lagos were randomly sampled (with a questionnaire), and 100 'home video' films were analyzed. Data were analyzed for: elements of world view; elements that pertain to illness in general; elements that pertain to psychotic illness; how such illness is to be treated. The world view has a significant influence on perception of psychotic illness. It is necessary to understand a people's world view in order to understand (and influence) attitudes towards psychotic illness in themselves and other people.

Thyroid hormone plays a crucial role in the growth and function of the central nervous system. The purpose of the study was to examine the relationships between the status of subclinical thyroid conditions and cognition among adolescents in the United States. Study sample included 1,327 adolescents 13 to 16 years old who participated in the Third National Health and Nutrition Examination Survey (NHANES III). Serum thyroxine (T4) and thyroid stimulating hormone (TSH) were measured and subclinical hypothyroidism, subclinical hyperthyroidism, and euthyroid groups were defined. Cognitive performance was assessed using the subscales of the Wide Range Achievement Test-Revised (WRAT-R) and the Wechsler Intelligence Scale for Children-Revised (WISC-R). The age-corrected scaled scores for arithmetic, reading, block design, and digit span were derived from the cognitive assessments. Subclinical hypothyroidism was found in 1.7% and subclinical hyperthyroidism was found in 2.3% of the adolescents. Cognitive assessment scores on average tended to be lower in adolescents with subclinical hyperthyroidism and higher in those with subclinical hypothyroidism than the score for the euthyroid group. Adolescents with subclinical hypothyroidism had significantly better scores in block design and reading than the euthyroid subjects even after adjustment for a number of variables including sex, age, and family income level. Subclinical hypothyroidism was associated with better performance in some areas of cognitive functions while subclinical hyperthyroidism could be a potential risk factor.

Full Text Available BackgroundA diagnosis of psychotic disorder is traditionally considered incompatible with borderline personality disorder (BPD, even though patients sometimes fulfill the diagnostic criteria for both disorders. How often this happens is barely known, as is the influence of comorbid psychotic disorders on the outcome of BPD. Since studies on isolated auditory verbal hallucinations in patients with BPD indicate that these perceptual symptoms have severe consequences and are associated with suicidal behavior and hospitalization, patients with comorbid psychotic disorders are unlikely to fare better.ObjectiveTo examine the point prevalence of psychotic disorders in patients with BPD, their association with the outcome of BPD, and their predictive value for outcome.MethodsIn a cross-sectional design, 84 female outpatients diagnosed with BPD were interviewed with the aid of the MINI-International Neuropsychiatric Interview to establish the point prevalence of comorbid psychotic and other comorbid disorders. After termination of their treatment at a specialized outpatient clinic, the type of referral was considered to be a “good” outcome when they were referred to their general practitioner or to basic psychiatric care for noncomplex patients, and a “poor” outcome when referred to a specialized psychiatric department or to a psychiatric district team for patients with severe psychiatric disorders.ResultsPsychotic disorders were present in 38% of the patients with BPD. With a prevalence of 20%, psychotic disorder not otherwise specified (NOS was the most common subtype; the least common types were schizophrenia (2%, substance-induced psychotic disorder (2%, and brief psychotic disorder (1%. Among six types of comorbid disorders, only psychotic disorders were associated with a poor outcome; they were also predictors for a poor outcome, along with comorbid mood disorders, eating disorders, and somatoform disorders, as well as the severity of BPD

2011-01-01

Hallervorden-Spatz disease is a rare neurological disorder characterized by pyramidal and extrapyramidal manifestations, dysarthria and dementia. Its onset is usually in childhood and most patients have a fatal outcome in few years. A high percentage of cases are hereditary with a recessive autosomal pattern. In the majority of the patients reported, a mutation of the gene that encodes the pantothenate kinase (PANK2) located in the 20p13-p12.3 chromosome that causes iron storage in the basal ganglia of the brain has been found. Its diagnosis is based on clinical symptoms as well as specific MRI imaging findings. The most common psychiatric features are cognitive impairment as well as depressive symptoms. There are few documented cases with psychotic disorders. We present the case of a patient with late onset Hallervorden-Spatz disease and psychotic symptoms that preceded the development of neurological manifestations. The pathophysiology and the treatment of psychotic symptomatology are presented and discussed. Key words: Psicosis, Hallervorden-Spatz, late onset, Basal ganglia.

Background and Aim: Patients with chronic kidney disease (CKD) often have subclinical hypothyroidism. However, few reports have investigated changes in the status of subclinical hypothyroidism in CKD patients and its clinical significance in CKD progression. Methods: We included 168 patients with nondialysis-dependent CKD stages 2-4. The normalization of subclinical hypothyroidism during follow-up was assessed, and the association between transitions in subclinical hypothyroid status and the rate of decline of the estimated glomerular filtration rate (eGFR) was investigated. Results: At baseline, 127 patients were euthyroid and 41 (24.4%) patients were diagnosed with subclinical hypothyroidism. Of these 41 patients, 21 (51.2%) spontaneously resolved to euthyroid during follow-up. The rate of eGFR decline of patients with resolved subclinical hypothyroidism was similar to that of euthyroid patients. The patients with unresolved subclinical hypothyroidism showed a steeper renal function decline than patients with euthyroidism or resolved subclinical hypothyroidism (all p hypothyroidism than in those who were euthyroid (p = 0.006). In multivariate linear regression for rate of eGFR decrease, unresolved subclinical hypothyroidism (β = -5.77, p = 0.001), baseline renal function (β = -0.12, p hypothyroidism did not resolve to euthyroidism, and this lack of resolution was independently associated with rapid renal function decline.

Subclinical hypothyroidism in childhood - current knowledge and open issues.

Salerno, Mariacarolina; Capalbo, Donatella; Cerbone, Manuela; De Luca, Filippo

2016-12-01

Subclinical hypothyroidism is defined as serum levels of TSH above the upper limit of the reference range, in the presence of normal concentrations of total T 4 or free T 4 . This biochemical profile might be an indication of mild hypothyroidism, with a potential increased risk of metabolic abnormalities and cardiovascular disease recorded among adults. Whether subclinical hypothyroidism results in adverse health outcomes among children is a matter of debate and so management of this condition remains challenging. Mild forms of untreated subclinical hypothyroidism do not seem to be associated with impairments in growth, bone health or neurocognitive outcome. However, ongoing scientific investigations have highlighted the presence of subtle proatherogenic abnormalities among children with modest elevations in their TSH levels. Although current findings are insufficient to recommend levothyroxine treatment for all children with mild asymptomatic forms of subclinical hypothyroidism, they highlight the potential need for assessment of cardiovascular risk among children with this condition. Increased understanding of the early metabolic risk factors associated with subclinical hypothyroidism in childhood will help to improve the management of affected individuals.

Full Text Available A lot of people live situations of mental sickness, from psychotic character, that can cause sufferingboth for the sick and his family. We believe that try this situation means to live with limitations and wearings in thefamiliar everyday, what makes difficult the living with the psychotic person. Considering these aspects, thisresearch has the purpose of knowing the familiar perception about his living with a psychotic bearer person. It isabout a qualitative, explorative and descriptive study, developed in a northwest city of Rio Grande do Sul state,called Ijuí. The people of the investigation are composed of five psychotic’s parents, which frequent the socioterapygroup in Gloria district. The information collection happened trough open interviews, recorded and wrote out at all.The analysis of the obtained data followed MINAYO’s (2002 methodological proposition. By the containedinformation in the stud’s social actor’s declarations, emerged three thematic with a similar nucleus of thoughts. Onfirst thematic, we discussed about the difficulties faced by the familiars in the living with the psychotic in themoment he has the acute symptoms. On the second thematic, we talked about the medical question as bring atherapeutic element that helps the mental sick to keep stable., becoming better the familiars life. The third thematicshows the family conception about mental sickness. With this research we concluded that the living with a mentalsick person is taxing for the familiar and, sometimes, there are difficulties to understand the symptoms showed bythe sick person. Besides that, the family considers the medication one of the most important possibilities ofintervention in the psychotic’s therapy, what is reinforced by the health team that leads with these people.

Convulsive therapy and its progeny, electroconvulsive therapy (ECT), were originally used for the treatment of catatonic schizophrenia, and there is little doubt that ECT remains an effective intervention for the treatment of schizophrenia. However, current practice tends to favor the use of ECT in severe or treatment refractory affective disorders, and its use in schizophrenia and other nonaffective (atypical) psychotic disorders has become controversial.CASE REPORTS HAVE SUGGESTED A ROLE FOR ECT IN TWO SPECIFIC ATYPICAL PSYCHOTIC DISORDERS: Cotard's syndrome and cycloid psychosis. In this article, we review the atypical psychotic disorders and report a series of five case examples that signify the role of ECT in atypical psychotic presentations, particularly when the symptoms resemble those found in Cotard's syndrome and cycloid psychosis.

Cerebral correlates of psychotic syndromes in neurodegenerative diseases.

Science.gov (United States)

Jellinger, Kurt A

2012-05-01

Psychosis has been recognized as a common feature in neurodegenerative diseases and a core feature of dementia that worsens most clinical courses. It includes hallucinations, delusions including paranoia, aggressive behaviour, apathy and other psychotic phenomena that occur in a wide range of degenerative disorders including Alzheimer's disease, synucleinopathies (Parkinson's disease, dementia with Lewy bodies), Huntington's disease, frontotemporal degenerations, motoneuron and prion diseases. Many of these psychiatric manifestations may be early expressions of cognitive impairment, but often there is a dissociation between psychotic/behavioural symptoms and the rather linear decline in cognitive function, suggesting independent pathophysiological mechanisms. Strictly neuropathological explanations are likely to be insufficient to explain them, and a large group of heterogeneous factors (environmental, neurochemical changes, genetic factors, etc.) may influence their pathogenesis. Clinico-pathological evaluation of behavioural and psychotic symptoms (PS) in the setting of neurodegenerative and dementing disorders presents a significant challenge for modern neurosciences. Recognition and understanding of these manifestations may lead to the development of more effective preventive and therapeutic options that can serve to delay long-term progression of these devastating disorders and improve the patients' quality of life. A better understanding of the pathophysiology and distinctive pathological features underlying the development of PS in neurodegenerative diseases may provide important insights into psychotic processes in general. © 2011 The Author Journal of Cellular and Molecular Medicine © 2011 Foundation for Cellular and Molecular Medicine/Blackwell Publishing Ltd.

Full Text Available State of subclinical hypothyroidism can be considered as the optimal model for assessing the significance of thyroid stimulating hormone (TSH for bone tissue in clinical practice. Objective: to make a comparative analysis of the impact of subclinical hyperthyroidism of various origins on the performance of bone mineral density (BMD and bone metabolism parameters. Materials and methods. The study in an outpatient setting included 112 women with a diagnosis of subclinical hyperthyroidism and duration of menopause for at least 5 years. Among the examinees, endogenous subclinical hyperthyroidism has been detected in 78 women (group I, exogenous subclinical hyperthyroidism on the background of suppressive levothyroxine therapy (group II — in 34. The control group (group III included 20 women without thyroid dysfunction. Results. The study first conducted a comparative analysis of bone metabolism, BMD indicators, as well as parameters of phosphorus and calcium, blood lipids in women with subclinical hyperthyroidism of various origins. A positive correlation between markers of bone metabolism and free triiodothyronine (fT3 as hormones necessary for the development of the skeleton and to maintain its homeostasis indicates a physiological effect of parathyroid hormone and fT3 on bone tissue. It is shown that the bone metabolism and BMD depend not only on the content of TSH, but also on the causes of subclinical hyperthyroidism.Conclusions. In postmenopausal women with endogenous subclinical hyperthyroidism, there is a significant decline in BMD indices, more pronounced in the bones with the cortical structure. A negative correlation between markers of bone metabolism and TSH has been observed among all patients included in the study.

Black and minority ethnic (BME) groups are known to have higher prevalences of psychotic disorders and are over-represented in western penitentiaries and forensic psychiatric institutions. Research from regular mental healthcare settings suggests that they could show different and more severe psychotic symptoms. Aims To explore ethnic variations in severity of symptomatology of BME and non-BME detainees with psychotic disorders. In this study, 824 patients with psychotic disorders from seven different ethnic groups, imprisoned in a penitentiary psychiatric centre in the Netherlands, were compared on symptom severity and symptom representation using the BPRS-E clinical interview. Data were analysed by means of a multilevel analysis. BME patients with psychotic disorders are over-represented in forensic psychiatry, and symptom profiles of prisoners with psychotic disorders vary by ethnicity. Additionally, severity levels of overall psychopathology differ between ethnic groups: patients with an ethnic majority status show more severe levels of psychopathology compared with BME patients. There are differences in symptom severity and symptom profiles between BME patients and non-BME patients. Disregarding these differences could have an adverse effect on the outcome of the treatment. Possible explanations and clinical impact are discussed. Declaration of interest None.

Usher syndrome is a heterogeneous autosomal recessive disorder characterized by hearing and visual sensory impairment. Retinitis pigmentosa is essential for its diagnosis. There are only a few reports describing patients with Usher syndrome presenting with psychotic features and the etiology of its psychiatric manifestation is still unknown. Herein, the authors report variable congenital hearing impairment and progressive visual loss occurring in five of seven family members and two of them meeting the diagnostic criteria of Usher syndrome with psychotic features. Furthermore, the authors compare their psychiatric symptoms with other reports and the possible etiologies of psychotic symptoms are discussed.

An experiment to determine the effect of gamma-ray irradiation in debilitating Streptococcus agalactiae as a cause of subclinical mastitis (inflammation of the udder) in cows has been conducted. S. agalactiae bacteria was isolated from subclinical mastitis found in dairy cows in the field was then observed for its cell growth. The bacteria which have reached mid-log phase of growth, were divided into 5 treatment groups, of which each was irradiated at dose level of 0; 25; 50; 75; and 100Gy. Irradiated bacteria subsequently were grown on Brain Heart Infusion agar (BHI), and each of its colonies was counted for LD50 determination. The obtained curves from irradiated treatment bacterial shown viability percentage by the linier equation of Y = 95.414 e -0,0371X ; R 2 = 0.9979, while Y = % viability and X = dose of irradiation. The calculation done in this experiment shows that irradiation dose of 17.4 Gy weaken the bacteria pathogenicity of S. agalactiae to the level of LD 50 . (author)

It has been suggested that the family history of psychotic disorders is useful in defining homogeneous groups of bipolar patients. The plasma homovanillic acid (pHVA) concentrations have been related to the effect of antipsychotic treatment in psychotic patients. We have studied the influence of a positive family history of psychotic disorders both on the variation of pHVA levels and on the relation between pHVA concentrations and the clinical response to treatment. Clinical status and pHVA levels were assessed in 58 medication free patients before and after 4 weeks of treatment with olanzapine and lithium. Clinical improvement correlated positively with pHVA levels on the 28th day of treatment only in the patients having first degree relatives with psychotic disorders. The pHVA levels did not decrease after 28 days of treatment. Our results reinforce the idea that a positive family history of psychosis in psychotic bipolar disorders may constitute a good basis for sub-grouping these patients.

Full Text Available BACKGROUND Psychotic disorders are a group of chronic debilitating psychiatric illness characterised by loss in touch with reality and disorders of thought, behaviour, appearance and speech. The second generation atypical antipsychotic olanzapine has been reported to be the commonly prescribed antipsychotic. However, olanzapine can cause adverse effects like weight gain, hyperglycaemia, diabetes, dyslipidaemia and metabolic syndrome. Quetiapine, another second generation antipsychotic has good efficacy and has become well established in the treatment of schizophrenia and manic episodes. There are reports on adverse effects of hyperglycaemia and diabetes with quetiapine, but these are comparatively lesser than olanzapine. The aim of the study is to compare the efficacy of olanzapine and quetiapine in patients with psychotic disorders. MATERIALS AND METHODS It was an unicentric, open label, prospective and comparative clinical study. Subjects (n=80 who were diagnosed with psychotic disorder were randomly assigned to receive olanzapine (group 1 or quetiapine (group 2. The efficacy of the two drugs was assessed on the basis Brief Psychiatric Rating Scale (BPRS scores at baseline, 1 week and 6 weeks. UKU scale (Udvalg Kliniske Undersogelser and laboratory investigations were used to assess the safety profile. RESULTS The two study groups had comparable sociodemographic profile. Both the groups showed significant reduction in psychotic symptoms as compared from baseline to 1 week and 6 weeks (p<0.001. The intergroup comparison of the efficacy of the two groups did not show any statistically significant results. There was statistically insignificant differences in the occurrence of adverse effects in both the groups. Sedation (50% in both the groups was the most common adverse effect in both the groups. The use of concomitant medications was comparable in both the groups. Benzodiazepines (56.3% in the olanzapine group and 51.9% in the quetiapine group

The present study aimed to examine the prevalence of child abuse across the continuum of psychosis. The sample consisted of 198 individuals divided in three groups: (1) 48 FEP patients, (2) 77 individuals scoring high in Community Assessment of Psychic Experiences (CAPE), classified as "High CAPE" group and (3) 73 individuals scoring low, classified as "Low CAPE" group. Childhood abuse was assessed using self-report instruments. Chi(2) tests and logistic regression models controlling by sex, age and cannabis were used to perform three comparisons: (i) FEP vs. Low CAPE; (ii) FEP vs. High CAPE and (iii) High CAPE vs. Low CAPE. The frequency of individuals exposed to childhood abuse for FEP, High CAPE and Low CAPE groups were 52.1%, 41.6% and 11%, respectively. FEP and High CAPE group presented significantly higher rates of childhood abuse compared to Low CAPE group, however, no significant differences were found between FEP and High CAPE groups regarding the frequency of childhood abuse. There is an increasing frequency of childhood abuse from low subclinical psychosis to FEP patients. However, childhood abuse is equally common in FEP and at risk individuals.

2014-01-01

Impairments in social cognition are now recognized as core illness features in psychotic and affective disorders. Despite the significant disability caused by social cognitive abnormalities, treatments for this symptom dimension are lacking. Here, we describe the evidence demonstrating abnormalities in social cognition in schizophrenia, major depressive disorder, and bipolar disorder, as well as the neurobiology of social cognition including the role of oxytocin. We then review clinical trials of oxytocin administration in psychotic and affective disorders and the impact of this agent on social cognition. To date, several studies have demonstrated that oxytocin may improve social cognition in schizophrenia; too few studies have been conducted in affective disorders to determine the effect of oxytocin on social cognition in these disorders. Future work is needed to clarify which aspects of social cognition may be improved with oxytocin treatment in psychotic and affective disorders. PMID:25153535

Genetic variation in AKT1 may be associated with sensitivity to the psychotomimetic effects of cannabis as well as with increased risk for psychotic disorder following cannabis use. Investigation of the effect of this interaction on relevant intermediate phenotypes for psychosis, such as cognition, may help to clarify the underlying mechanism. Thus, verbal memory (visually presented Word Learning Task), sustained attention (Continuous Performance Test, CPT), AKT1 rs2494732 genotype, and cannabis use were examined in a large cohort of patients with psychotic disorder. No evidence was found for AKT1 × cannabis interaction on verbal memory. Cannabis use preceding onset of psychotic disorder did interact significantly with AKT1 rs2494732 genotype to affect CPT reaction time (β=8.0, SE 3.9, p=0.037) and CPT accuracy (β=-1.2, SE 0.4, p=0.003). Cannabis-using patients with the a priori vulnerability C/C genotype were slower and less accurate on the CPT, whereas cannabis-using patients with the T/T genotype had similar or better performance than non-using patients with psychotic disorder. The interaction was also apparent in patients with psychotic disorder who had not used cannabis in the 12 months preceding assessment, but was absent in the unaffected siblings of these patients and in healthy controls. In conclusion, cannabis use before onset of psychosis may have long-lasting effects on measures of sustained attention, even in the absence of current use, contingent on AKT1 rs2494732 genotype. The results suggest that long-term changes in cognition may mediate the risk-increasing effect of the AKT1 × cannabis interaction on psychotic disorder.

Potential Benefits of Incorporating Peer-to-Peer Interactions Into Digital Interventions for Psychotic Disorders: A Systematic Review.

Biagianti, Bruno; Quraishi, Sophia H; Schlosser, Danielle A

2018-04-01

Peer-to-peer interactions and support groups mitigate experiences of social isolation and loneliness often reported by individuals with psychotic disorders. Online peer-to-peer communication can promote broader use of this form of social support. Peer-to-peer interactions occur naturally on social media platforms, but they can negatively affect mental health. Recent digital interventions for persons with psychotic disorders have harnessed the principles of social media to incorporate peer-to-peer communication. This review examined the feasibility, acceptability, and preliminary efficacy of recent digital interventions in order to identify strategies to maximize benefits of online peer-to-peer communication for persons with psychotic disorders. An electronic database search of PubMed, EMBASE, PsycINFO, Ovid MEDLINE, Cochrane Central Register of Controlled Trials, and Health Technology Assessment Database was conducted in February 2017 and yielded a total of 1,015 results. Eight publications that reported data from six independent trials and five interventions were reviewed. The technology supporting peer-to-peer communication varied greatly across studies, from online forums to embedded social networking. When peer-to-peer interactions were moderated by facilitators, retention, engagement, acceptability, and efficacy were higher than for interventions with no facilitators. Individuals with psychotic disorders were actively engaged with moderated peer-to-peer communication and showed improvements in perceived social support. Studies involving service users in intervention design showed higher rates of acceptability. Individuals with psychotic disorders value and benefit from digital interventions that include moderated peer-to-peer interactions. Incorporating peer-to-peer communication into digital interventions for this population may increase compliance with other evidence-based therapies by producing more acceptable and engaging online environments.

Neurological Soft Signs In Psychoses A Comparison Between Schizophrenia & Other Psychotic Disorders

2002-07-01

Full Text Available Schizophrenia is one of the most important and disabling mental disorders in the world. Males and females are equally affected. Diagnosis is a very difficult problem in this disorder. Because the diagnostic systems such as ICD-10 and DSM-IV are mainly subjective, they are not valid and reliable. Essentially, in the future, we will need to more objective criteria in psychiatry especially in diagnosis of schizophrenia. Neurological soft signs are an example of these objective criteria. In this study we evaluated the prevalence of neurological soft signs in schizophrenic patients and compared it with the prevalence of these signs in other psychotic patients (except mood disorders with psychotic features and normal subjects."nMethods: We compared the neurological soft signs (sensory motor integration, motor. Coordination, consequent complex motor acts, primary reflexes, and eye movements in 30 schizophrenic patients, 30 other psychotic patients (other than mood disorders with psychotic features and 30 normal subjects. Diagnosis of schizophrenia and also other psychoses were based on DSM-IN criteria. Normal subjects have been selected form the staff of Roozbeh hospital randomly."nResults: The difference between the means of motor coordination subscale of neurological soft signs in schizophrenia and other psychotic disorders (other than mood disorders with psychotic features were significant (P value < 0.04. There were no significant differences between the means of other subscales of neurological soft signs in two groups of patients."nConclusion: There are some disturbances of motor coordination subscale of neurological soft signs in patients with schizophrenia. It seems that, these disturbances are evidence of involvements of basal ganglia, motor cerebral cortex, and cerebellum. So it may be suggested that motor coordination as a marker can be used in differentiation between the schizophrenia and other psychotic disorders.

2009-01-01

Narcolepsy is an uncommon chronic, neurological disorder characterized by abnormal manifestations of rapid eye movement sleep and perturbations in the sleep-wake cycle. Accurate diagnosis of psychotic symptoms in a person with narcolepsy could be difficult due to side effects of stimulant treatment (e.g., hallucinations) as well as primary symptoms of narcolepsy (e.g., sleep paralysis and hypnagogic and/or hypnapompic hallucinations). Pertinent articles from peer-reviewed journals were identified to help understand the complex phenomenology of psychotic symptoms in patients with narcolepsy. In this ensuing review and discussion, we present an overview of narcolepsy and outline diagnostic and management approaches for psychotic symptoms in patients with narcolepsy. PMID:19724760

Interpersonal sensitivity defines feelings of inner-fragility in the presence of others due to the expectation of criticism or rejection. Interpersonal sensitivity was found to be related to attenuated positive psychotic symptom during the prodromal phase of psychosis. The aims of this study were to examine if high level of interpersonal sensitivity at baseline are associated with the persistence of attenuated positive psychotic symptoms and general psychopathology at 18-month follow-up. A sample of 85 help-seeking individuals (mean age = 16.6, SD = 5.05) referred an Italian early detection project, completed the interpersonal sensitivity measure and the structured interview for prodromal symptoms (SIPS) at baseline and were assessed at 18-month follow-up using the SIPS. Results showed that individuals with high level of interpersonal sensitivity at baseline reported high level of attenuated positive psychotic symptoms (i.e., unusual thought content) and general symptoms (i.e., depression, irritability and low tolerance to daily stress) at follow-up. This study suggests that being "hypersensitive" to interpersonal interactions is a psychological feature associated with attenuated positive psychotic symptoms and general symptoms, such as depression and irritability, at 18-month follow-up. Assessing and treating inner-self fragilities may be an important step of early detection program to avoid the persistence of subtle but very distressing long-terms symptoms.

Objective: To evaluate the prevalence of subclinical thyroid disease (SCTD) in local population visiting a hospital laboratory for thyroid function tests. Design: It was a hospital - based study carried in consecutive patients who reported for thyroid function tests in the hospital laboratory. Place and duration of study: The study was conducted in combined military Hospital, Quetta during June 1999 to September 2000. Subject and methods: Serum samples of 917 patients living in Quetta and its surrounding were analysed for thyroid stimulating hormone (TSH) free thyroxin (FT4), and total tri-iodothyronine (T3) concentration using chemiluminescence technique on hormone auto analyser (LIA-Mat - Sangtech Germany). Results: Out of 917 patients, 287 (23%) were found to be having SCTD while overt thyroid disease was found in 288 (31%) patients. Prevalence of sub-clinical hypothyroidism (SCO) and sub-clinical hyperthyroidism (sce) was found to be almost equal with a profound female preponderance in both the groups. SCO was more common in children (<12 years of age). Conclusion: Almost every fourth patient reporting for thyroid function tests was diagnosed as having SCTD - a disease entity that is still not well known and that poses diagnostic and management problems for the pathologists and clinicians.

. To examine racial-ethnic differences in the endorsement and attribution of psychotic-like symptoms in a nationally representative sample of African-Americans, Asians, Caribbean Blacks, and Latinos living in the USA. Data were drawn from a total of 979 respondents who endorsed psychotic-like symptoms as part of the National Latino and Asian American Study (NLAAS) and the National Survey of American Life (NSAL). We use a mixed qualitative and quantitative analytical approach to examine sociodemographic and ethnic variations in the prevalence and attributions of hallucinations and other psychotic-like symptoms in the NLAAS and NSAL. The lifetime presence of psychotic-like symptoms was assessed using the World Health Organization Composite International Diagnostic Interview (WMH-CIDI) psychotic symptom screener. We used logistic regression models to examine the probability of endorsing the four most frequently occurring thematic categories for psychotic-like experiences by race/ethnicity (n > 100). We used qualitative methods to explore common themes from participant responses to open ended questions on their attributions for psychotic-like symptoms. African-Americans were significantly less likely to endorse visual hallucinations compared to Caribbean Blacks (73.7% and 89.3%, p supernatural, ghosts/unidentified beings, death and dying, spirituality or religiosity, premonitions, familial and other. Respondents differed by race/ethnicity in the attributions given to psychotic like symptoms. Findings suggest that variations exist by race/ethnicity in both psychotic-like symptom endorsement and in self-reported attributions/understandings for these symptoms on a psychosis screening instrument. Ethnic/racial differences could result from culturally sanctioned beliefs and idioms of distress that deserve more attention in conducting culturally informed and responsive screening, assessment and treatment.

Subclinical Hypothyroidism in Children and Adolescents: Is It Clinically Relevant?

Directory of Open Access Journals (Sweden)

Aneta Gawlik

2015-01-01

Full Text Available Although subclinical hypothyroidism (SH is a common clinical problem, its diagnosis tends to be incidental. According to the definition, it should be asymptomatic, only detectable by screening. The presence or coincidence of any symptoms leads to L-thyroxine treatment. The clinical presentation, especially in younger patients with subclinical hypothyroidism, is still under dispute. Accordingly, the aim of this paper was to review the literature from the past seven years. The literature search identified 1,594 potentially relevant articles, of which 24 met the inclusion criteria. Few studies focus on the symptomatology of subclinical hypothyroidism, and most of them analyzed a small number of subjects. A significant correlation was found by some authors between subclinical hypothyroidism and a higher risk of hypertension, dyslipidemia, and migraine. No evidence of the impact of subclinical hypothyroidism on weight, growth velocity, and puberty was revealed. As the quality of most studies is poor and no definite conclusions can be drawn, randomized, large-scale studies in children and adolescents are warranted to determine the best care for patients with SH.

Subclinical Hyperthyroidism: When to Consider Treatment.

Science.gov (United States)

Donangelo, Ines; Suh, Se Young

2017-06-01

Subclinical hyperthyroidism is defined by a low or undetectable serum thyroid-stimulating hormone level, with normal free thyroxine and total or free triiodothyronine levels. It can be caused by increased endogenous production of thyroid hormone (e.g., in Graves disease, toxic nodular goiter, or transient thyroiditis), by administration of thyroid hormone to treat malignant thyroid disease, or by unintentional excessive replacement therapy. The prevalence of subclinical hyperthyroidism in the general population is about 1% to 2%; however, it may be higher in iodinedeficient areas. The rate of progression to overt hyperthyroidism is higher in persons with thyroid-stimulating hormone levels less than 0.1 mIU per L than in persons with low but detectable thyroid-stimulating hormone levels. Subclinical hyperthyroidism is associated with an increased risk of atrial fibrillation and heart failure in older adults, increased cardiovascular and all-cause mortality, and decreased bone mineral density and increased bone fracture risk in postmenopausal women. However, the effectiveness of treatment in preventing these conditions is unclear. A possible association between subclinical hyperthyroidism and quality-of-life parameters and cognition is controversial. The U.S. Preventive Services Task Force found insufficient evidence to assess the balance of benefits and harms of screening for thyroid dysfunction in asymptomatic persons. The American Thyroid Association and the American Association of Clinical Endocrinologists recommend treating patients with thyroid-stimulating hormone levels less than 0.1 mIU per L if they are older than 65 years or have comorbidities such as heart disease or osteoporosis.

Subclinical hyperthyroidism is defined as normal serum free thyroxine and a free triiodothyronine level, with a thyroid-stimulating hormone level suppressed below the normal range and is usually undetectable. Although patients with this diagnosis have no or few signs and symptoms of overt thyrotoxicosis, there is sufficient evidence that it is associated with a relatively higher risk of supraventricular arrhythmias as well as the acceleration or the development of osteoporosis. Consequently, the approach to the patient with subclinical hyperthyroidism is controversial, that is, therapeutic intervention versus watchful waiting. Regardless, it is imperative for the referring physician to identify the causative thyroid disorder. This is optimally accomplished by a functional study, namely scintigraphy. Recognition of the scan findings of the various causes of subclinical hyperthyroidism enables the imaging specialist to help in diagnosing the underlying condition causing thyroid-stimulating hormone suppression thereby facilitating the workup and management of this thyroid disorder.

There is considerable variation in negative and positive symptoms of psychosis, global functioning, and emotional face perception (EFP), not only in schizophrenia but also in other psychotic disorders and healthy individuals. However, EFP impairment and its association with worse symptoms and global functioning have been examined largely in the domain of schizophrenia. The present study adopted a dimensional approach to examine the association of behavioral and neural measures of EFP with symptoms of psychosis and global functioning across individuals with schizophrenia spectrum (SZ; N = 28) and other psychotic (OP; N = 29) disorders, and never-psychotic participants (NP; N = 21). Behavioral and functional MRI data were recorded as participants matched emotional expressions of faces and geometrical shapes. Lower accuracy and increased activity in early visual regions, hippocampus, and amygdala during emotion versus shape matching were associated with higher negative, but not positive, symptoms and lower global functioning, across all participants. This association remained even after controlling for group-related (SZ, OP, and NP) variance, dysphoria, and antipsychotic medication status, except in amygdala. Furthermore, negative symptoms mediated the relationship between behavioral and brain EFP measures and global functioning. This study provides some of the first evidence supporting the specific relationship of EFP measures with negative symptoms and global functioning across psychotic and never-psychotic samples, and transdiagnostically across different psychotic disorders. Present findings help bridge the gap between basic EFP-related neuroscience research and clinical research in psychosis, and highlight EFP as a potential symptom-specific marker that tracks global functioning.

This study investigates the comorbidity and longitudinal associations between self-reported conduct disorder and subclinical bulimia in a community-based sample of Finnish adolescents in a 2-year prospective follow-up study. There are 2070 adolescents who participated in the survey as ninth graders (mean age 15.5) and followed-up 2 years later. The Youth Self-Report Externalizing scale was used to measure conduct disorder and DSM-IV-based questionnaire to measure bulimia. Co-occurrence of female conduct disorder and subclinical bulimia was found at ages 15 and 17. Subclinical bulimia among girls at age 15 was a risk factor for conduct disorder at age 17, but conduct disorder at age 15 was not predictive of subclinical bulimia at age 17. The pathway from bulimia to conduct disorder may be suggestive of an association with future borderline personality disorder among girls.

Full Text Available Introduction:Increased cardiovascular risk in thyroid dysfunction is associated with disorders of lipid and lipoproteins, endothelial dysfunction, metabolic, hormonal, hemodynamic changes and coagulation disorders. Subclinical hypothyroidism is characterized by a suprarnormal level of TSH with normal levels of thyroid hormones. The correlation between subclinical hypothyroidism of the lipid profile and cardiovascular outcomes remains unclear. Several intervention studies assessed the effect of levothyroxine therapy on the lipid profile of patients with subclinical hypothyroidism and obtained conflicting results. The aim of the research is to determine whether subclinical hypothyroidism is associated with the atherogenic lipid profile and whether these changes are reversible after the introduction of the L-thyroxine replacement therapy. Method: The study included 51 patients over 50 years of age with subclinical hypothyroidism. All the participants were subjected to an examination programme which included a detailed anamnesis and physical examination, laboratory tests (total cholesterol, LDL cholesterol, HDL cholesterol, triglycerides, T3, T4, TSH. After eight weeks of levothyroxine therapy, the same laboratory parameters were determined in the patients. Results: Subjects with subclinical hypothyroidism had high average values: TSH (12.77 + 2.78 mIU / ml, total cholesterol (7.55 ± 0.79 mmol / l, LDL cholesterol (5.03 ± 0.61 mmol / l, triglycerides (2.48 ± 1.01 mmol / l; and the average value of HDL cholesterol was within reference values (1.12 ± 0.21 mmol / l. After eight weeks of levothyroxine replacement therapy, there was a statistically significant reduction of average values (p <0.0001: TSH (3.83 ± 1.33 mIU / ml, total cholesterol (6.28 ± 0.96 mmol / l, LDL cholesterol ( 4.03 ± 0.70 mmol / mmol / l l, triglycerides (1.98 ± 0.87 mmol / l; and the average value of HDL cholesterol increased significantly (p <0.0001 (1.32 ± 0.22 mmol

In this study we examined the hypothesis that depression and anxiety may mediate the relationship between personality traits and both positive and negative psychotic-like experiences (PLEs) in healthy adults. The Community Assessment of Psychic Experiences (CAPE) scale, Temperament and Character Inventory (TCI), Beck Depression Inventory (BDI) and State and Trait Anxiety Inventory (STAI) were administered to 492 healthy individuals. Multiple stepwise regression and mediation analyses were performed to examine whether depressive and anxiety symptoms influence the relationship between the TCI dimensions and positive and negative PLEs. Self-transcendence, persistence, novelty-seeking and self-directedness significantly predicted positive PLEs; self-directedness and harm avoidance were predictable for negative PLEs. Self-transcendence, self-directedness, persistence and harm avoidance also predicted the distress caused by positive PLEs, whereas self-directedness and harm avoidance predicted distress raised by negative PLEs. Depressive symptoms and the state of anxiety partially mediated the linkage between self-directedness and positive PLEs, and between self-directedness, harm avoidance and negative PLEs. Our findings confirm that the personality pattern influences both positive and negative PLEs as well as distress caused by experiencing positive and negative PLEs, and they indicate that certain personality traits may influence the development of PLEs via the emotional pathway of heightened depression and anxiety.

Abstract Background There is renewed interest in the relationship between early childhood trauma and risk of psychosis in adulthood. Trauma and stressful events in childhood and adolescence are known to be more prevalent among individuals with schizophrenia and other psychotic disorders than in the general population. Furthermore, other findings support the role of childhood trauma as a socio-environmental risk factor for psychotic symptoms, and research on the potential etiological relationship between trauma/stressful events in childhood/adolescence and psychotic disorders is evolving. The aim of the current study was to examine relations among all items and domains of childhood trauma and schizophrenic symptoms in patients with schizophrenia. The relationship between types of trauma and their association with psychotic symptoms was analysed. Methods In this study, we collected data from 50 schizophrenic patients (39 males and 11 females). All patients met the DSM 5 criteria for schizophrenia. Psychotic symptoms were measured by the Positive and Negative Syndrome Scale (PANSS). Trauma and stressful events in childhood and adolescence were assessed using the Childhood Trauma Questionnaire (CTQ). Results We found significant correlations between emotional and sexual abuse, emotional neglect and denial scale in CTQ with positive symptoms of the PANSS (pagressive behaviours was also described in litterature. These results went along with the stress sensitization model where the HPA axis is over-active and excessively reactive to the subsequent environemental stressors causing positive symptoms of the disease.

Counterfactual Reasoning in Non-psychotic First-Degree Relatives of People with Schizophrenia

Directory of Open Access Journals (Sweden)

Auria eAlbacete

2016-05-01

Full Text Available Counterfactual thinking (CFT is a type of conditional reasoning that enables the generation of mental simulations of alternatives to past factual events. Previous research has found this cognitive feature to be disrupted in schizophrenia. At the same time, the study of cognitive deficits in unaffected relatives of people with schizophrenia has significantly increased, supporting its potential endophenotypic role in this disorder. Using an exploratory approach, the current study examined CFT for the first time in a sample of non-psychotic first-degree relatives of schizophrenia patients (N=43, in comparison with schizophrenia patients (N=54 and healthy controls (N=44. A series of tests that assessed the causal order effect in CFT and the ability to generate counterfactual thoughts and counterfactually derive inferences using the Counterfactual Inference Test was completed. Associations with variables of basic and social cognition, levels of schizotypy and psychotic-like experiences in addition to clinical and sociodemographic characteristics were also explored. Findings showed that first-degree relatives generated a lower number of counterfactual thoughts than controls, and were more adept at counterfactually deriving inferences, specifically in the scenarios related to regret and to judgements of avoidance in an unusual situation. No other significant results were found. These preliminary findings suggest that non-psychotic first-degree relatives of schizophrenia patients show a subtle disruption of global counterfactual thinking compared with what is normally expected in the general population. Because of the potential impact of such deficits, new treatments targeting CFT improvement might be considered in future management strategies.

While contemporary models of psychosis have proposed a number of putative psychological mechanisms, how these impact on individuals to increase intensity of psychotic experiences in real life, outside the research laboratory, remains unclear. We aimed to investigate whether elevated stress sensitivity, experiences of aberrant novelty and salience, and enhanced anticipation of threat contribute to the development of psychotic experiences in daily life. We used the experience sampling method (ESM) to assess stress, negative affect, aberrant salience, threat anticipation, and psychotic experiences in 51 individuals with first-episode psychosis (FEP), 46 individuals with an at-risk mental state (ARMS) for psychosis, and 53 controls with no personal or family history of psychosis. Linear mixed models were used to account for the multilevel structure of ESM data. In all 3 groups, elevated stress sensitivity, aberrant salience, and enhanced threat anticipation were associated with an increased intensity of psychotic experiences. However, elevated sensitivity to minor stressful events (χ2 = 6.3, P = 0.044), activities (χ2 = 6.7, P = 0.036), and areas (χ2 = 9.4, P = 0.009) and enhanced threat anticipation (χ2 = 9.3, P = 0.009) were associated with more intense psychotic experiences in FEP individuals than controls. Sensitivity to outsider status (χ2 = 5.7, P = 0.058) and aberrantly salient experiences (χ2 = 12.3, P = 0.002) were more strongly associated with psychotic experiences in ARMS individuals than controls. Our findings suggest that stress sensitivity, aberrant salience, and threat anticipation are important psychological processes in the development of psychotic experiences in daily life in the early stages of the disorder.

Background Data on the association between subclinical thyroid dysfunction and fractures conflict. Purpose To assess the risk for hip and nonspine fractures associated with subclinical thyroid dysfunction among prospective cohorts. Data Sources Search of MEDLINE and EMBASE (1946 to 16 March 2014) and reference lists of retrieved articles without language restriction. Study Selection Two physicians screened and identified prospective cohorts that measured thyroid function and followed participants to assess fracture outcomes. Data Extraction One reviewer extracted data using a standardized protocol, and another verified data. Both reviewers independently assessed methodological quality of the studies. Data Synthesis The 7 population-based cohorts of heterogeneous quality included 50 245 participants with 1966 hip and 3281 nonspine fractures. In random-effects models that included the 5 higher-quality studies, the pooled adjusted hazard ratios (HRs) of participants with subclinical hyperthyroidism versus euthyrodism were 1.38 (95% CI, 0.92 to 2.07) for hip fractures and 1.20 (CI, 0.83 to 1.72) for nonspine fractures without statistical heterogeneity (P = 0.82 and 0.52, respectively; I2 = 0%). Pooled estimates for the 7 cohorts were 1.26 (CI, 0.96 to 1.65) for hip fractures and 1.16 (CI, 0.95 to 1.42) for nonspine fractures. When thyroxine recipients were excluded, the HRs for participants with subclinical hyperthyroidism were 2.16 (CI, 0.87 to 5.37) for hip fractures and 1.43 (CI, 0.73 to 2.78) for nonspine fractures. For participants with subclinical hypothyroidism, HRs from higher-quality studies were 1.12 (CI, 0.83 to 1.51) for hip fractures and 1.04 (CI, 0.76 to 1.42) for nonspine fractures (P for heterogeneity = 0.69 and 0.88, respectively; I2 = 0%). Limitations Selective reporting cannot be excluded. Adjustment for potential common confounders varied and was not adequately done across all studies. Conclusion Subclinical hyperthyroidism might be associated with

In this study, we researched the effects of maternal subclinical hypothyroidism on the amniotic fluid cells oxidative metabolism during the first trimester of pregnancy. Oxidative stress and damage biomarkers were assayed in the amniotic fluid cells of healthy and pregnant women with subclinical hypothyroidism. Obtained results show that amniotic fluid cells of pregnant women with subclinical hypothyroidism have significantly higher concentrations of oxidative stress biomarkers (superoxide anion, nitric oxide, peroxynitrite) and oxidative damage (lipid peroxide and micronuclei frequency), but lower concentrations of hydrogen peroxide and oxidized glutathione in comparison to healthy pregnant women. We also showed that oxidative stress biomarkers were positively correlated with micronuclei frequency and lipid peroxide concentration in amniotic fluid cells of pregnant women with subclinical hypothyroidism. The present study provides the first evidence for prooxidative effects of maternal subclinical hypothyroidism on the fetus obtained by the estimating oxidative metabolism in the amniotic fluid cells.

Right heart function and mechanics have not been investigated in patients with subclinical hyperthyroidism. Our aim was to investigate right ventricular (RV) and right atrial (RA) function and deformation as evaluated by 3-dimensional echocardiography (3DE) and speckle-tracking 2-dimensional echocardiography (2DE) in these individuals. We included 39 untreated women with endogenous subclinical hyperthyroidism and 39 healthy women matched by age. All participants underwent laboratory analyses that included thyroid hormone levels and comprehensive 2DE and 3DE examinations. Three-dimensional echocardiographic RV volumes were significantly elevated in the patients with subclinical hyperthyroidism (P < .05), whereas the 3DE RV ejection fraction was reduced in this group, but with borderline significance. Two-dimensional echocardiographic longitudinal RV and RA strain were significantly reduced in the patients with subclinical hyperthyroidism. Two-dimensional echocardiographic RV systolic and early diastolic strain rates were reduced, whereas late diastolic strain rates were increased in the patients with subclinical hyperthyroidism. The same changes were detected in RA mechanics among the patients with subclinical hyperthyroidism. The thyrotropin (TSH) level correlated with the left ventricular mass index, transmitral early diastolic peak flow velocity (E)/late diastolic flow velocity (A) ratio, tricuspid E/A ratio, 2DE RV global strain, 2DE RA, strain, and 3DE RV end-diastolic volume. A multivariate regression analysis showed that the mitral E/A ratio, 2DE RV global strain, and 3DE RV end-diastolic volume were independently associated with the TSH level. Right ventricular and RA function as evaluated by 3DE and speckle-tracking 2DE is significantly impaired in patients with subclinical hyperthyroidism. The TSH level correlated with parameters for RV function and mechanics in the whole study population. © 2016 by the American Institute of Ultrasound in Medicine.

Several neuroimaging studies report reduced hippocampal volume in depressed patients. However, it is still unclear if hippocampal changes in healthy individuals can be considered a risk factor for progression to clinical depression. Here, we investigated subclinical depression and its hippocampal correlates in a non-clinical sample of healthy individuals, with particular regard to gender differences. One-hundred-two participants underwent a comprehensive clinical assessment, a high-resolution T1-weighted magnetic resonance imaging and diffusion tensor imaging protocol using a 3T MRI scanner. Data of macro-(volume) and micro-(mean diffusivity, MD) structural changes of the hippocampus were analyzed with reference to the Beck Depression Inventory score. Results of multivariate regression analyses revealed reduced bilateral volume, along with increased bilateral MD in hippocampal formation predicting subclinical depressive phenomenology only in healthy males. Conversely, subclinical depressive phenomenology in healthy female was accounted for by only lower educational level, in the absence of any hippocampal structure variations. To date, this is the only evidence reporting a relationship between subclinical depressive phenomenology and changes in hippocampal formation in healthy individuals. Our findings demonstrated that reduced volume, along with increased MD in hippocampal formation, is significantly associated with subclinical depressive phenomenology in healthy males. This encourages to study the hypothesis that early macro- and microstructural changes in hippocampi associated with subclinical depression may constitute a risk factor of developing depressive disorders in males. © 2013 Elsevier B.V.

Full Text Available Soo-Hyun Joo, Jong-Hyun Jeong, Seung-Chul HongDepartment of Psychiatry, St Vincent's Hospital, College of Medicine, The Catholic University of Korea, Suwon, KoreaAbstract: Abnormalities in thyroid function are associated with many psychiatric symptoms. We present a report of a 15-year-old girl who was admitted to the psychiatry inpatient unit with symptoms of suicidal behavior, irritability, and impulsivity. One year previously, she had become more short-tempered, and had started to cut her wrists impulsively. Laboratory tests revealed subclinical hyperthyroidism. She was treated with anxiolytic and antithyroid drugs, and her suicidal ideation and irritability resolved. This case demonstrates that subclinical hyperthyroidism can be associated with suicidal behavior as well as overt hyperthyroidism. Early intervention is required to prevent suicidal behavior in patients with subclinical hyperthyroidism.Keywords: suicidal behavior, subclinical hyperthyroidism, anxiolytics

Evidence suggests that social networks of patients with psychotic disorders influence symptoms, quality of life and treatment outcomes. It is therefore important to assess social networks for which appropriate and preferably established instruments should be used. To identify instruments assessing social networks in studies of patients with psychotic disorders and explore their properties. A systematic search of electronic databases was conducted to identify studies that used a measure of social networks in patients with psychotic disorders. Eight instruments were identified, all of which had been developed before 1991. They have been used in 65 studies (total N of patients = 8,522). They assess one or more aspects of social networks such as their size, structure, dimensionality and quality. Most instruments have various shortcomings, including questionable inter-rater and test-retest reliability. The assessment of social networks in patients with psychotic disorders is characterized by a variety of approaches which may reflect the complexity of the construct. Further research on social networks in patients with psychotic disorders would benefit from advanced and more precise instruments using comparable definitions of and timescales for social networks across studies.

The prevalence, as well as the effect of subclinical ketosis on daily milk yield, was observed using 1.299,630 test-day records collected from January 2000 to December 2005 on 73,255 Slovenian Holstein cows. Subclinical ketosis was indicated by the fat to protein ratio (F/P ratio) higher than 1.5 in cows that yielded between 33 to 50 kg of milk per day (Eicher, 2004). The ketosis index was defined in relation to the timing of subclinical ketosis detection to the subsequent measures of test-da...

Subclinical delusional ideation and a self-reference bias in everyday reasoning.

Galbraith, Niall; Manktelow, Ken; Morris, Neil

2008-02-01

Previous studies (e.g. Moller & Husby, 2000; Blackwood et al., 2004) have revealed that delusional thinking is accompanied by an exaggerated focus upon the self and upon stimuli that are perceived to be related to the self. The objective was to examine whether those high in subclinical delusional ideation exhibit a heightened tendency for self-reference. Using a mixed design, healthy individuals, classified into high- and low-scoring groups on the Peters et al. Delusions Inventory (Peters, Day, & Garety, 1996), were compared on everyday reasoning tasks across three experiments. High-PDI scorers, in contrast to the low-PDI group, rated self-referent objections to everyday arguments as stronger than other-referent objections and formulated more self-referent assertion-based objections to everyday arguments. The findings support the notion that subclinical delusional ideation is linked to a self-reference bias, which is evident in the sort of everyday thinking that people engage in when forming or evaluating their beliefs and which may contribute to delusion formation.

Association of subclinical hypothyroidism with type 2 diabetes and its complications has been previously documented. These reports were, however, inconclusive and mainly gathered from Chinese and East Asian populations. In this study, we aimed to determine the prevalence of subclinical hypothyroidism and its relationship with diabetic nephropathy in Iranian individuals with type 2 diabetes, drawn from a white Middle Eastern population with an increasing prevalence of diabetes. In this cross-sectional study, 255 Iranian participants with type 2 diabetes and without history of thyroid disorders were included. Patients with TSH > 4.2 mIU/L and normal T4 were classified as having subclinical hypothyroidism. Diabetic nephropathy was diagnosed based on abnormal 24-h urinary albumin or protein measurements (24-h urinary albumin ≥30 mg/day or 24-h urinary protein ≥150 mg/day). Multivariate logistic regression was employed to obtain the OR for the relationship between subclinical hypothyroidism and diabetic nephropathy. We found that subclinical hypothyroidism and diabetic nephropathy were as prevalent as 18.1 and 41.2 %, respectively, among the participants. We also found that subclinical hypothyroidism was independently associated with higher rates of diabetic nephropathy, after multivariable adjustment (OR [95 % CI] 3.23 [1.42-7.37], p = 0.005). We found that the prevalence of subclinical hypothyroidism in Iranian diabetic population was among the highest rates reported to date. Our data supported the independent association of subclinical hypothyroidism with diabetic nephropathy, calling for further investigations to evaluate their longitudinal associations.

To determine the occurrence of subclinical rickets and its causing factors among adolescent students of schools in Kaghan Valley, Pakistan. Observation cross-sectional study. Department of Biochemistry and Health Sciences, Hazara University, Mansehra, Ayub Medical College and Teaching Hospital, Abbottabad, from March to April 2012. Sixty seven students (34 boys and 33 girls) age between 11 - 16 years included in the study from different schools of Kaghan Valley, Pakistan. Characteristic, serum biochemical and nutritional status were measured for all the participants. On the basis of biochemical finding the boys and girls students were divided in to two groups, normal subjects and subclinical rickets (absent symptoms with altered biochemistry). Twenty six participants, 19 (73%) girls and 07 (27%) boys had biochemical abnormality but no clinical signs and symptoms of rickets. Low vitamin D and high alkaline phosphatase level were observed in 26 (100%), 21 (81%), low calcium in 17 (65%) and low phosphorus 7 (27%) subjects with subclinical rickets. None had high parathormone level above normal range. Nutritional intake of calcium, phosphorus and vitamin D was found less than the recommended daily intake in all the participants. Subclinical rickets is common problem among adolescent students especially in girls which is due to low nutritional intakes and avoidance of sunshine due to environmental and traditional impacts.

While contemporary models of psychosis have proposed a number of putative psychological mechanisms, how these impact on individuals to increase intensity of psychotic experiences in real life, outside the research laboratory, remains unclear. We aimed to investigate whether elevated stress sensitivity, experiences of aberrant novelty and salience, and enhanced anticipation of threat contribute to the development of psychotic experiences in daily life. We used the experience sampling method (ESM) to assess stress, negative affect, aberrant salience, threat anticipation, and psychotic experiences in 51 individuals with first-episode psychosis (FEP), 46 individuals with an at-risk mental state (ARMS) for psychosis, and 53 controls with no personal or family history of psychosis. Linear mixed models were used to account for the multilevel structure of ESM data. In all 3 groups, elevated stress sensitivity, aberrant salience, and enhanced threat anticipation were associated with an increased intensity of psychotic experiences. However, elevated sensitivity to minor stressful events (χ(2)= 6.3,P= 0.044), activities (χ(2)= 6.7,P= 0.036), and areas (χ(2)= 9.4,P= 0.009) and enhanced threat anticipation (χ(2)= 9.3,P= 0.009) were associated with more intense psychotic experiences in FEP individuals than controls. Sensitivity to outsider status (χ(2)= 5.7,P= 0.058) and aberrantly salient experiences (χ(2)= 12.3,P= 0.002) were more strongly associated with psychotic experiences in ARMS individuals than controls. Our findings suggest that stress sensitivity, aberrant salience, and threat anticipation are important psychological processes in the development of psychotic experiences in daily life in the early stages of the disorder. © The Author 2016.

Psychotic disorders in DSM-5 and ICD-11.

Science.gov (United States)

Biedermann, Falko; Fleischhacker, W Wolfgang

2016-08-01

The Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5) was published by the American Psychiatric Association (APA) in 2013, and the Work Group on the Classification of Psychotic disorders (WGPD), installed by the World Health Organization (WHO), is expected to publish the new chapter about schizophrenia and other primary psychotic disorders in 2017. We reviewed the available literature to summarize the major changes, innovations, and developments of both manuals. If available and possible, we outline the theoretical background behind these changes. Due to the fact that the development of ICD-11 has not yet been completed, the details about ICD-11 are still proposals under ongoing revision. In this ongoing process, they may be revised and therefore have to be seen as proposals. DSM-5 has eliminated schizophrenia subtypes and replaced them with a dimensional approach based on symptom assessments. ICD-11 will most likely go in a similar direction, as both manuals are planned to be more harmonized, although some differences will remain in details and the conceptual orientation. Next to these modifications, ICD-11 will provide a transsectional diagnostic criterion for schizoaffective disorders and a reorganization of acute and transient psychotic and delusional disorders. In this manuscript, we will compare the 2 classification systems.

To assess the prevalence of psychotic symptoms among youths (14-25 years of age) with a childhood diagnosis of attention-deficit/hyperactivity disorder (ADHD) combined type. Participants in the Multimodal Treatment Study of Children with ADHD (MTA) and a local normative comparison group (LNCG) were systematically assessed 6, 8, 10, 12, 14, and 16 years after the original enrollment at a mean age of 8.5 years. Trained research assistants administered a psychosis screener, and positive screens were referred to study clinicians to confirm or exclude psychosis. Possible associations between screening positive and alcohol or substance use were assessed. Data were available from 509 MTA participants (88% of original MTA sample; mean age 25.1 years) and 276 LNCG participants (96% of original sample; mean age 24.6 years) at year 16. Twenty-six MTA participants (5%; 95% CI 3-7) and 11 LNCG participants (4%; 95% CI 2-6) screened positive for at least 1 psychotic symptom (p = .60). Most psychotic symptoms were transient. The prevalence of clinician-confirmed psychotic symptoms was 1.1% (95% CI 0.2-2.1) in the MTA group and 0.7% (0-1.7) in the LNCG (p = .72). Greater cannabis use was reported by those who screened positive (p ADHD increased the risk for psychotic symptoms. In the ADHD and normative comparison groups, more frequent cannabis use was associated with a greater likelihood of experiencing psychotic symptoms, thus supporting the recommendation that youth should not use cannabis.

Childhood trauma (CT) has been identified as a potential risk factor for the onset of psychotic disorders. However, to date, there is limited consensus with respect to which symptoms may ensue after exposure to trauma in early life, and whether specific pathways may account for these associations. The aim of the present study was to use the novel network approach to investigate how different types of traumatic childhood experiences relate to specific symptoms of psychotic disorders and to identify pathways that may be involved in the relationship between CT and psychosis. We used data of patients diagnosed with a psychotic disorder (n = 552) from the longitudinal observational study Genetic Risk and Outcome of Psychosis Project and included the 5 scales of the Childhood Trauma Questionnaire-Short Form and all original symptom dimensions of the Positive and Negative Syndrome Scale. Our results show that all 5 types of CT and positive and negative symptoms of psychosis are connected through symptoms of general psychopathology. These findings are in line with the theory of an affective pathway to psychosis after exposure to CT, with anxiety as a main connective component, but they also point to several additional connective paths between trauma and psychosis: eg, through poor impulse control (connecting abuse to grandiosity, excitement, and hostility) and motor retardation (connecting neglect to most negative symptoms). The results of the current study suggest that multiple paths may exist between trauma and psychosis and may also be useful in mapping potential transdiagnostic processes. © The Author 2016.

Structural and functional perspectives on classification and seriation in psychotic and normal children.

Science.gov (United States)

Breslow, L; Cowan, P A

1984-02-01

This study describes a strategy for examining cognitive functioning in psychotic and normal children without the usual confounding effects of marked differences in cognitive structure that occur when children of the same age are compared. Participants were 14 psychotic children, 12 males and 2 females, mean age 9-2, matched with normal children at preoperational and concrete operational stage levels on a set of Piagetian classification tasks. The mean age of the normal children was 6-4, replicating the usually found developmental delay in psychotic samples. Participants were then compared on both structural level and functional abilities on a set of tasks involving seriation of sticks; the higher-level children were also administered a seriation drawing task. Analysis of children's processes of seriating and seriation drawings indicated that over and above the structural retardation, psychotic children at all levels showed functional deficits, especially in the use of anticipatory imagery. The implications for general developmental theory are that progress in structural development is not sufficient for imaginal development, and that structural development of logical concepts is relatively independent of the development of imagery. It was suggested that "thought disorder" may not be a disordered structure of thinking or a retardation in psychotic populations but rather a mismatch between higher-level logical structures and lower-level functions.

Knowledge on the risk mechanisms of psychotic experiences (PE) is still limited. The aim of this population-based study was to explore developmental markers of PE with a particular focus on the specificity of hyper-theory-of-mind (HyperToM) as correlate of PE as opposed to correlate of any mental disorder. We assessed 1630 children from the Copenhagen Child Cohort 2000 regarding PE and HyperToM at the follow-up at 11-12 years. Mental disorders were diagnosed by clinical ratings based on standardized parent-, teacher- and self-reported psychopathology. Logistic regression analyses were performed to test the correlates of PE and HyperToM, and the specificity of correlates of PE v. correlates of any Diagnostic and Statistical Manual of Mental Disorders, 4th edition (DSM-IV) mental disorder. Univariate analyses showed the following correlates of PE: familial psychiatric liability; parental mental illness during early child development; change in family composition; low family income; regulatory problems in infancy; onset of puberty; bullying; concurrent mental disorder; and HyperToM. When estimating the adjusted effects, only low family income, concurrent mental disorder, bullying and HyperToM remained significantly associated with PE. Further analyses of the specificity of these correlates with regard to outcome revealed that HyperToM was the only variable specifically associated with PE without concurrent mental disorder. Finally, HyperToM did not share any of the investigated precursors with PE. HyperToM may have a specific role in the risk trajectories of PE, being specifically associated with PE in preadolescent children, independently of other family and child risk factors associated with PE and overall psychopathology at this age.

This study first aimed to establish the prevalence and predictors of subclinical seizures in patients with epilepsy undergoing video electroencephalographic monitoring, then to evaluate the relationship of sleep/wake and circadian pattern with subclinical seizures. We retrospectively reviewed the charts of 742 consecutive patients admitted to our epilepsy center between July 2012 and October 2014. Demographic, electro-clinical data and neuroimage were collected. A total of 148 subclinical seizures were detected in 39 patients (5.3%) during video electroencephalographic monitoring. The mean duration of subclinical seizures was 47.18 s (range, 5-311). Pharmacoresistant epilepsy, abnormal MRI and the presence of interictal epileptiform discharges were independently associated with subclinical seizures in multivariate logistic regression analysis. Subclinical seizures helped localizing the presumed epileptogenic zone in 24 (61.5%) patients, and suggested multifocal epilepsy in five (12.8%). In addition, subclinical seizures occurred more frequently in sleep and night than wakefulness and daytime, respectively, and they were more likely seen between 21:00-03:00 h, and less likely seen between 09:00-12:00 h. Thirty patients (76.9%) had their first subclinical seizures within the first 24 h of monitoring while only 7.7% of patients had their first subclinical seizures detected within 20 min. Subclinical seizures are not uncommon in patients with epilepsy, particularly in those with pharmacoresistant epilepsy, abnormal MRI or interictal epileptiform discharges. Subclinical seizures occur in specific circadian patterns and in specific sleep/wake distributions. A 20-min VEEG monitoring might not be long enough to allow for their detection.

In the field of dual diagnosis, physicians are frequently presented with pharmacological questions. Questions about the risk of developing psychotic symptoms in cocaine users who need treatment with dopaminergic drugs could lead to an undertreatment. Review the presence of psychotic symptoms in patients with cocaine abuse/dependence, in treatment with dopaminergic drugs. Systematic PubMed searches were conducted including December 2014, using the keywords: "cocaine", dopaminergic drug ("disulfuram-methylphenidate-bupropion-bromocriptine-sibutramineapomorphine- caffeine") and ("psychosis-psychotic symptoms-delusional-paranoia"). Articles in English, Spanish, Portuguese, French, and Italian were included. Articles in which there was no history of cocaine abuse/dependence, absence of psychotic symptoms, systematic reviews, and animal studies, were excluded. 313 papers were reviewed. 7 articles fulfilled the inclusion-exclusion criteria. There is a clinical trial including 8 cocaine-dependent patients using disulfiram in which 3 of them presented psychotic symptoms and 6 case-reports: disulfuram (1), methylphenidate (1), disulfiram with methylphenidate (2), and bupropion (2), reporting psychotic symptoms, especially delusions of reference and persecutory ideation. Few cases have been described, which suggests that the appearance of these symptoms is infrequent. The synergy of dopaminergic effects or the dopaminergic sensitization in chronic consumption are the explanatory theories proposed by the authors. In these cases, a relationship was found between taking these drugs and the appearance of psychotic symptoms. Given the low number of studies found, further research is required. The risk of psychotic symptoms seems to be acceptable if we compare it with the benefits for the patients but a closer monitoring seems to be advisable.

Through conceptualising poor insight in psychotic disorders as a form of anosognosia, frontal lobe dysfunction is often ascribed a vital role in its pathogenesis. The objective of this study was to compare the relation of insight in patients with psychotic illness to that of psychopathology and frontal lobe function. Forty patients with psychotic disorder were selected from those attending the Department of Psychiatry in a tertiary care teaching hospital. The evaluation of insight was carried out using the Schedule for Assessment of Insight (SAI), that of frontal lobe function by the Frontal Assessment Battery (FAB) and psychopathology by the Brief Psychiatric Rating Scale (BPRS). The correlation coefficients were determined. A negative correlation between SAI and BPRS scores means that the BPRS score is opposite to SAI scores. When the SAI total score was compared with the FAB total score, the correlation coefficient demonstrated a positive correlation. Better insight predicted lesser psychopathology and also that poor insight would exist with greater psychopathology. Better insight predicted a higher functional status of frontal lobes and prefrontal cortex in particular. Insight deficits in schizophrenia and other psychotic illnesses are multidimensional. Integration of different aetiological factors like biological, psychopathological, environmental ones and others are necessary for a better understanding of insight in psychosis. Copyright © 2013 S.

Myxedema coma is the extreme manifestation of hypothyroidism, typically seen in patients with severe biochemical hypothyroidism. Its occurrence in association with subclinical hypothyroidism is extremely unusual. We describe a patient with subclinical hypothyroidism who developed clinical manifestations of myxedema coma. A 47-year-old woman presented to our endocrine clinic with complaints of fatigue and biochemical findings of subclinical hypothyroidism. She was started on treatment with thyroxine (T4) but remained unwell and was later admitted to hospital with hormone profile showing persisting subclinical hypothyroidism (elevated thyrotropin and normal free T4 [FT4] and free triiodothyronine [FT3]): FT4 10.7 pmol/L (reference range 10.3-24.5), FT3 2.7 pmol/L (reference range 2.67-7.03), and thyrotropin 6.09 mU/L (reference range 0.4-4.0). She subsequently developed hypothermia (temperature 33.2°C), circulatory collapse, and coma. Biochemical profile showed hyponatremia, elevated creatinine phosphokinase, metabolic acidosis, and renal failure. An echocardiogram revealed a moderate-sized pericardial effusion. We diagnosed myxedema coma and started treatment with intravenous T3. She responded dramatically with improvement in level of consciousness and normalization of metabolic parameters. We found no explanation other than hypothyroidism to account for the presentation. Adrenocorticotrophic hormone (ACTH) stimulation tests excluded adrenal insufficiency, and serum gonadotrophins were within the normal reference range. FT4 estimation by equilibrium dialysis excluded analytical interference, and molecular analysis for the thyroid hormone receptor β gene associated with thyroid hormone resistance was negative. To the best of our knowledge this is the first report of myxedema coma in a patient with subclinical hypothyroidism. The reason for normal thyroid hormone levels is unclear but may reflect deviation from a higher pre-morbid set-point. The case

The goal of this study was to determine the effectiveness of the third person interview in increasing the level of insight and cooperation in psychotic patients. We used a quasi-experimental posttest design with an alternative method group. A number of 40 individuals with a definite diagnosis of psychosis were selected using a simple random sampling, and were put randomly in an experimental group (third person interview) and an alternative control group (clinical interview). The results indicated that using the third person interview, the insight level of the psychotic patients increased in all dimensions of insight, except awareness of flat or blunted affect and awareness of unsociability. The results of the independent t-test samples showed no significant difference in cooperation between the two groups of psychotic patients. It seems that the ability to consider one's mental viewpoint from other's, is dependent on the relative ability of psychotic patients to represent other's mental states (theory of mind). But, psychotic patients have severe impairment in the ability to represent their own mental states, resulting in an impairment in the recognition of their mental disorder, psychotic symptoms, the need for therapy, and social consequences of their mental disorder.

Fernández, B.; Betancourt, V.C.; Padilla, P.; De la Barca, M.

2016-01-01

Subclinical hypercortisolism (HS) is diagnosed in a patient with no Cushing's syndrome manifest phenotype but with autonomic cortisol secretion. Harmful effects of chronic subtle excess of cortisol have been demonstrated, such as hypertension (AHT), type 2 diabetes mellitus (DM2) or glucose intolerance, obesity, osteoporosis, vertebral fractures and dyslipidemia. It has been suggested that subclinical hypercortisolism may itself be a vascular risk factor. In order to identify the presence of subclinical hypercortisolism and its main clinical manifestations in patients with adrenal incidentalomas treated at the endocrinology service of the 'Arnaldo Milian Castro' Clinical Surgical Hospital, a descriptive cross-sectional investigation was carried out from 2012 to 2015 The sample of intentional type was made up of 34 patients older than 18 years and diagnosis of adrenal incidentalomas. Age, sex, toxic habits, questioning results, physical examination and the necessary diagnostic investigations were analyzed. The results showed a predominance of females, over 60 years old, with toxic habits and family and personal history of hypertension and DM2. Palpitations, low back pain, asthenia and obesity with pigmentation of the skin were the most frequent clinical manifestations. Hyperglycemia, dyslipidemia, and elevated levels of cortisol occurred in the majority of patients. Imaging diagnosis showed left lesions and less than 4.0 cm and adrenal adenoma was the most frequent histopathological diagnosis. It was demonstrated that subclinical hypercortisolism is present in an important group of patients with adrenal incidentalomas, is not as asymptomatic, and is related to the presence of vascular risk factors, and other comorbidities

The parricide is defined as "murder of the father or the mother or any other legitimate ascendant." It represents 1 to 5% of all homicides and 20 to 30% of psychotic homicides. In Tunisia, few studies have focused on this issue. We propose in this work to describe the profile of psychotic parricide. We tried to identify risk factors in order to prevent this acting out. Our study is retrospective we observed 16 male patients diagnosed with schizophrenia hospitalized between June 1979 and March 2008 in the forensic psychiatry department at the psychiatric hospital in Tunis, discharged for no ground for prosecution following parricide. They accounted for 20.8% of psychotic homicides hospitalized during the same period (16/77) and approximately 30% of homicides committed by schizophrenic patients. We found as many as patricide as matricide. The main factors that have emerged through our study are an early age (28 years), being single (70%), the socio-cultural poverty, unemployment, paranoid delusions, hallucinations and recent treatment interruption. All these factors have been cited by many authors including Millaud et al, they also cited history of violence and violent behavior and alcohol or drug abuse. One important point is that some signs of this imminent gesture are often present but misunderstood, such a sense of situational impasse, a request for help, or reluctance during interview. It is essential to identify risk factors, even to actively seek some warning signs, which often are not spontaneously reported by the psychotic patient. Hospitalization under constraint in psychiatry should be the appropriate response if these dangerousness signals are noticed by the psychiatrist.

Current and emerging somatic treatment strategies in psychotic major depression.

Psychotic major depressive disorder (MDD) is a mood disorder characterized by severe affective and neurovegetative symptoms together with the presence of delusions and/or hallucinations. It is a common disorder seen in a quarter of consecutively admitted depressed patients and is often associated with severe symptomatology, increased suicide risk, poor acute response to antidepressants and poor acute and long-term treatment outcome. It is possible that poor response in psychotic depression is caused by the fact that we have yet to identify the most efficacious treatment protocol for psychotic MDD. Multiple studies have shown that modifications in the treatment paradigm may increase treatment efficacy in psychotic MDD. It has been generally accepted that, during the acute treatment phase, antidepressant-antipsychotic drug combination therapy is more effective than either treatment alone, although this strategy has recently been challenged. The question of the optimal duration of pharmacotherapy in order to prevent relapse and improve long-term (i.e., 5-year) outcome is a focus of current investigation. This article will review currently recommended treatment strategies for the acute, continuation and maintenance phases of therapy. In particular, it will address the role of newer-generation antidepressants, the role of second-generation antipsychotics, the use of mood stabilizers and indications for electroconvulsive therapy. Other possible treatment strategies such as transcranial magnetic stimulation, vagus nerve stimulation, deep-brain stimulation and glucocorticoid receptor antagonists will be discussed. Current recommendations for the prevention of relapse and improvement of long-term outcome will be reviewed.

The 22q11.2 deletion syndrome (22q11DS) is associated with increased rates of psychotic disorders and cognitive deficits, but large scale studies are needed to elucidate their interaction. The objective of this two-center study was to identify the neurocognitive phenotype of individuals with 22q11DS and psychotic disorders. We hypothesized that psychotic 22q11DS individuals compared to nonpsychotic deleted individuals would have more severe neurocognitive deficits, especially in executive function and social cognition. These deficits would be present when compared to IQ- matched individuals with Williams Syndrome (WS). Three groups were ascertained from the Tel Aviv and Philadelphia centers: 22q11DS individuals with a psychotic disorder (n=31), nonpsychotic 22q11DS (n=86) and typically-developing controls (TD, n=828). In Tel Aviv a group of individuals with WS (n=18) matched in IQ to the 22q11DS psychotic group was also included. The Penn Computerized Neurocognitive Battery (CNB) was used to assess a wide-range of cognitive functions and all patients underwent structured psychiatric evaluations. 22q11DS individuals performed poorly on all CNB domains compared to TD. Participants with 22q11DS and psychosis, compared to nonpsychotic 22q11DS, had more severe deficits in global neurocognitive performance (GNP), executive function, social cognition and episodic memory domains. The primary deficits were also significant when comparing the Tel Aviv 22q11DS psychotic group to IQ-matched individuals with WS. In conclusion, 22q11DS individuals with a psychotic disorder have specific neurocognitive deficits that are reliably identified cross nationality using the CNB. These cognitive dysfunctions should be further studied as potential endophenotypes of psychosis in 22q11DS and as targets for intervention. Copyright © 2016 Elsevier B.V. and ECNP.

There has been considerable recent interest in possible causal linkages between exposure to bullying victimization and later psychotic symptomatology. Prior research in this area has had several limitations which make it difficult to ascertain causality, and to determine the extent to which these effects extend beyond adolescence. Data were obtained from the Christchurch Health and Development Study, a 35-year study of a longitudinal birth cohort. This investigation used generalized estimating equation modelling to estimate the associations between bullying victimization (ages 13-16 years) and psychotic symptoms (ages 18-35 years), before and after controlling for possible confounding factors, including: gender; childhood socio-economic status; child intelligence quotient; exposure to sexual abuse in childhood; anxious/withdrawn behaviour and attention problems (ages 7-9 years); and adolescent psychotic symptoms and paranoid ideation (ages 15-16 years). There was a significant (p bullying victimization in adolescence and psychotic symptomatology in adulthood. Successive models controlling for covariation reduced this association to statistical non-significance. After controlling for covariates, those with the highest level of bullying victimization had rates of psychotic symptoms that were 1.21 (95% confidence interval 0.73-1.99) times higher than those who were not victimized. The association between bullying victimization in adolescence and psychotic symptomatology in adulthood could be largely explained by childhood behavioural problems, and exposure to sexual abuse in childhood. The results suggest that bullying victimization was unlikely to have been a cause of adult psychotic symptoms, but bullying victimization remained a risk marker for these symptoms.

Thyroid function disorders lead to changes in the lipoprotein metabolism. To study the lipid and the glycaemic abnormalities in the subclinical hypothyroidism cases and to compare the same with the euthyroid, overt hypothyroid and the hyperthyroid subjects. Four groups, euthyroid (Group-I), hypothyroid (Group-II), subclinical hypothyroid (Group-III) and hyperthyroid (Group-IV), which consisted of 30 subjects each, of either sex, who were aged 25-55 years, underwent Fasting Plasma Glucose (FPG), fructosamine, lipid profile and total T3, T4 and TSH estimations. The subjects who were on lipid lowering or thyroid disorder drugs and known diabetics were excluded from the study. In Group-III, all the lipid fractions were comparable to those of Group-II and they were significantly deranged, as compared to those of Group-I. The fructosamine levels were significantly higher in Group-II and Group-III (phypothyrodism, the subclinical hypothyroid cases also need to be treated similarly. The fructosamine values which are largely in excess of the FPG values, indicate a higher propensity to glycation and a decreased turnover of the proteins in the hypothyroid and the subclinical hypothyroid pools. Vice versa is true of the hyperthyroid pool. Fructosamine can be included in the thyroid work up of the patients to assess the metabolic function and the subsequent response after the initiation of the therapy.

Objective: To determine the occurrence of subclinical rickets and its causing factors among adolescent students of schools in Kaghan Valley, Pakistan. Study Design: Observation cross-sectional study. Place and Duration of Study: Department of Biochemistry and Health Sciences, Hazara University, Mansehra, Ayub Medical College and Teaching Hospital, Abbottabad, from March to April 2012. Methodology: Sixty seven students (34 boys and 33 girls) age between 11 - 16 years included in the study from different schools of Kaghan Valley, Pakistan. Characteristic, serum biochemical and nutritional status were measured for all the participants. On the basis of biochemical finding the boys and girls students were divided in to two groups, normal subjects and subclinical rickets (absent symptoms with altered biochemistry). Results: Twenty six participants, 19 (73%) girls and 07 (27%) boys had biochemical abnormality but no clinical signs and symptoms of rickets. Low vitamin D and high alkaline phosphatase level were observed in 26 (100%), 21 (81%), low calcium in 17 (65%) and low phosphorus 7 (27%) subjects with subclinical rickets. None had high parathormone level above normal range. Nutritional intake of calcium, phosphorus and vitamin D was found less than the recommended daily intake in all the participants. Conclusion: Subclinical rickets is common problem among adolescent students especially in girls which is due to low nutritional intakes and avoidance of sunshine due to environmental and traditional impacts.

The association between cigarette smoking and psychosis remains unexplained, but could relate to causal effects in both directions, confounding by socioeconomic factors, such as ethnicity, or use of other substances, including cannabis. Few studies have evaluated the association between cigarettes and psychotic experiences (PEs) in diverse, inner-city populations, or relationships with number of cigarettes consumed. We assessed associations and dose-response relationships between cigarette smoking and PEs in a cross-sectional survey of household residents (n = 1680) in South East London, using logistic regression to adjust for cannabis use, other illicit substances, and socioeconomic factors, including ethnicity. We found association between any PEs and daily cigarette smoking, which remained following adjustment for age, gender, ethnicity, cannabis and use of illicit stimulant drugs (fully adjusted odds ratio 1.47, 95% confidence interval 1.01-2.15). Fully adjusted estimates for the association, and with number of PEs, increased with number of cigarettes smoked daily, implying a dose-response effect (p = 0.001 and <0.001, respectively). Odds of reporting any PEs in ex-smokers were similar to never-smokers. In this diverse epidemiological sample, association between smoking and PEs was not explained by confounders such as cannabis or illicit drugs. Daily cigarette consumption showed a dose-response relationship with the odds of reporting PEs, and of reporting a greater number of PEs. There was no difference in odds of reporting PEs between ex-smokers and never-smokers, raising the possibility that the increase in PEs associated with smoking may be reversible.

Psychotic relapse leads to repeated hospitalization and negatively affects the clinical prognosis of the patients. Information on prevalence of relapse among patients with psychotic disorders in Ethiopian setting is scarce. This study aimed to assess the prevalence of relapse among patients with psychotic disorders attending services in Jimma University Specialized Hospital (JUSH). Data were collected using interviewer administered questionnaire. We used medication adherence rating scale (MARS) to assess compliance to medication and abnormal involuntary movement scale (AIMS) to detect medication side effects. Logistic regression analysis was used to identify independent predictors of psychotic relapse. All variables with P-value value higher when compared to those who have never experienced medication side effects (aOR = 1.83, 95 % CI = 1.01, 3.31). The high prevalence of relapse among patients with psychotic disorder needs special attention. Clinicians need to pay attention to medication side effects the patient faces. Intervening noncompliance to medication and appropriately managing medication side effects may help in preventing psychotic relapse that may result because of non-compliance. The provision of counseling, psycho education, psycho social support may help patients in improving compliance to medication and reducing psychotic relapse. Developing and strengthening community based rehabilitation services should be emphasized as part of mental healthcare services.

To evaluate the frequency of non-autoimmune subclinical and overt hypothyroidism in children with idiopathic steroid-resistant nephrotic syndrome (SRNS). This cross-sectional study recruited 30 children (age 1-18 y) with idiopathic SRNS; and 30 healthy controls. Serum T3, T4 and TSH were performed in cases as well as controls. Anti-thyroid peroxidase and anti-thyroglobulin antibody tests were performed in all cases. Non-autoimmune subclinical or overt hypothyroidism was detected in 10 out of 30 children with idiopathic SRNS; 2 had overt hypothyroidism, while 8 patients had subclinical hypothyroidism. Children with SRNS had a mean (SD) TSH value 4.55 (4.64) mIU/L that was higher as compared to controls (1.88 (1.04) mIU/L) (Phypothyroidism (2 cases) and grade III subclinical hypothyroidism (1 case) were subsequently started on levothyroxine therapy. The prevalence of subclinical and overt hypothyroidism seems to be high in idiopathic SRNS, with almost one-third of children having overt or subclinical non-autoimmune hypothyroidism.

Skin-picking disorder (SPD) was recognized as its own entity for the first time in DSM-5. The existing SPD literature is limited and, to date, no study has examined the differences between clinical and sub- clinical SPD. Identifying differences between these 2 groups may improve diagnostic accuracy, treatment, and prevention efforts. Israeli adults (N = 4,325) from 2 previous studies were examined for the presence of clinical and subclinical SPD. Individuals with clinical SPD (n = 150) vs subclinical SPD (n = 219) were compared on skin-picking characteristics, psychological phenomena, and clinical correlates. There were many similarities between clinical and subclinical skin pickers. Individuals with clinical SPD, however, had more severe skin picking, greater associated functional impairment, greater perceived stress, and greater depressive and obsessive-compulsive symptoms, and were also more likely to have a first-degree relative with SPD. This study suggests that although there are some similarities between clinical and subclinical SPD, there also are distinct differences in the clinical presentation. Understanding these differences may be an important factor in treatment and prevention planning.

Furnham, Adrian; Petropoulou, Kelly

2018-02-15

This study looked at lay theories of how people with sub-clinical personality disorders experience the world of work. The aim was to investigate the paradox that subclinical and clinical personality disorders are seen as beneficial for success, rather than a handicap in certain jobs. In all, 230 participants read 14 vignettes derived from Oldham and Morris's book describing DSMIII personality disorders for a popular audience. Participants were invited to suggest what type of work each disordered person may be successful at, as well as six ratings of their social adjustment. There was a tendency for people to believe those with OCD to be suited to Accountancy, Narcissism and Paranoia to General Management, Histrionic PD to being an Actor and Schizotypal an Artist. Surprisingly Paranoid and Sadistic people were judged to be good managers and Histrionic, Passive Aggressive and Schizotypal the worst. People in Cluster C were judged as best managers, but those in Cluster B as better adjusted. Results show that lay people believe that certain "dark-side" traits associated with personality disorders, particularly dependency and OCD, are thought to be beneficial for success, rather than failure, in many jobs.

Imagination in human social cognition, autism, and psychotic-affective conditions.

Complex human social cognition has evolved in concert with risks for psychiatric disorders. Recently, autism and psychotic-affective conditions (mainly schizophrenia, bipolar disorder, and depression) have been posited as psychological 'opposites' with regard to social-cognitive phenotypes. Imagination, considered as 'forming new ideas, mental images, or concepts', represents a central facet of human social evolution and cognition. Previous studies have documented reduced imagination in autism, and increased imagination in association with psychotic-affective conditions, yet these sets of findings have yet to be considered together, or evaluated in the context of the diametric model. We first review studies of the components, manifestations, and neural correlates of imagination in autism and psychotic-affective conditions. Next, we use data on dimensional autism in healthy populations to test the hypotheses that: (1) imagination represents the facet of autism that best accounts for its strongly male-biased sex ratio, and (2) higher genetic risk of schizophrenia is associated with higher imagination, in accordance with the predictions of the diametric model. The first hypothesis was supported by a systematic review and meta-analysis showing that Imagination exhibits the strongest male bias of all Autism Quotient (AQ) subscales, in non-clinical populations. The second hypothesis was supported, for males, by associations between schizophrenia genetic risk scores, derived from a set of single-nucleotide polymorphisms, and the AQ Imagination subscale. Considered together, these findings indicate that imagination, especially social imagination as embodied in the default mode human brain network, mediates risk and diametric dimensional phenotypes of autism and psychotic-affective conditions.

Accumulating evidence indicates an impact of childhood adversities on the severity and course of mental disorders, whereas this impact on psychotic disorders remains to be specified. Effects of childhood adversities on comorbidity, on symptom severity of the Positive and Negative Syndrome Scale and global functioning across four months (upon admission, 1 and 4 months after initial assessment), as well as the course of illness (measured by the remission rate, number of re-hospitalizations and dropout rate) were evaluated in 62 inpatients with psychotic spectrum disorders. Adverse experiences (of at least 1 type) were reported by 73% of patients. Patients with higher overall level of childhood adversities (n=33) exhibited more co-morbid disorders, especially alcohol/substance abuse and dependency, and higher dropout rates than patients with a lower levels of adverse experiences (n=29), together with higher levels of positive symptoms and symptoms of excitement and disorganization. Emotional and physical neglect were particularly related to symptom severity. Results suggest that psychological stress in childhood affects the symptom severity and, additionally, a more unfavorable course of disorder in patients diagnosed with psychoses. This impact calls for its consideration in diagnostic assessment and psychiatric care. Copyright © 2015 The Authors. Published by Elsevier Ireland Ltd.. All rights reserved.

Introduction: There are many factors causing endothelial dysfunction. The aim was to observe chosen markers of endothelial function in patients with subclinical and overt hyperthyroidism. Material and methods: We studied 97 patients with hyperthyroidism: 51 with subclinical (44 F/7 M; mean age 49.3 ± 15.9 y) and 46 patients with overt (39 F/7 M, mean age 50.4 ± 13.2 y). The control comprised of 39 healthy volunteers (26 F/13 M, mean age 47.5 ± 11.8 y). Concentration of TSH, FT3, FT4 were measured by MEIA, TPO Ab, TG Ab, E-selectin, interleukin 6, VCAM-1, ICAM-1 by ELISA. Results: The goiter was found in 71 persons 63F/8M, mean age 49.9 ± 15.3 y, (42-subclinical, 29-overt). Morbus Graves--Basedow was diagnosed in 26 persons, 20 F/6 M, mean age 49.5 ± 12.8 y (9-subclinical, 17-overt). There were no significant differences serum concentration of E-selectin, IL-6, ICAM-1 in patients with subclinical and overt hyperthyroidism compared to the control. Statistically significant differences were shown between concentration of IL-6 in patients with Graves-Basedow compared with the control (p < 0.05). Significance of VCAM-1 values were found in the patients with subclinical and overt hyperthyroidism compared to the control (p < 0.001; p < 0.001, respectively). Conclusions: Among persons with overt and subclinical hyperthyroidism occurs endothelial dysfunction which doesn't depends on exciting cause of thyrotoxicosis but on degree of hyperthyroidism. Elevated concentrations of endothelial markers may confirm that persons with thyroid disorders are extremely exposed to the occurrence of the cardiovascular diseases. (author)

Subclinical hyperthyroidism is an increasingly recognized entity that is defined as a normal serum free thyroxine and free triiodothyronine levels with a thyroid-stimulating hormone level suppressed below the normal range and usually undetectable. It has been reported that subclinical hyperthyroidism is not associated with coronary heart disease or mortality from cardiovascular causes but it is sufficient to induce arrhythmias including atrial fibrillation and atrial flutter. Nowadays, there is growing interest regarding endogenous sublinical hyperthyroidism and the cardiovascular system. We present a case of acute myocardial infarction without significant coronary stenoses in a 75-year-old Italian woman with endogenous subclinical hyperthyroidism. Also this case focuses attention on the importance of a correct evaluation of endogenous subclinical hyperthyroidism. Copyright © 2009 Elsevier Ireland Ltd. All rights reserved.

Several research groups have shown that people with schizophrenia who offend do not form a homogenous group. A three-group model claimed by Hodgins proposes distinguishing between people who start offending before the onset of psychosis (early starters), after psychosis onset but at age 34 years or under (late starters) and after psychosis onset but at age 35 years or older (late first offenders). This study aimed to test the hypotheses (1) that the personality of early starters and non-psychotic offenders would be similar, but different from either late-starter group; (2) that the late-starter groups would be more likely to have positive psychotic symptoms than non-criminal patients with schizophrenia; and (3) that symptom types would differentiate the psychotic groups. A retrospective file study was conducted on cases of 97 early starters, 100 late starters and 26 late first offenders all drawn from the Netherlands Institute of Forensic Psychiatry and Psychology (NIFP) archives 1993-2008, 115 non-psychotic offenders from 2005-2008 NIFP archives and 129 patients with schizophrenia and no criminal history from one general service in Rotterdam. Early starters closely resembled the non-psychotic offenders in their premorbid anti-social personality characteristics. The two late-onset offending psychosis groups were more likely to have persecutory and/or grandiose delusions than non-offenders with psychosis, but so were the early starters. In a first study to compare subgroups of offenders with psychosis directly with non-psychotic offenders and non-offenders with psychosis, we found such additional support for a distinction between early and late starters with psychosis that different treatment strategies would seem indicated, focusing on personality and substance misuse for the former but psychotic symptoms for all. It remains to be seen whether the higher rate of alcohol misuse amongst late first offenders is a fundamental distinction or a function of age

Subclinical thyroid disease during pregnancy may be associated with adverse outcomes, including a lower-than-normal IQ in offspring. It is unknown whether levothyroxine treatment of women who are identified as having subclinical hypothyroidism or hypothyroxinemia during pregnancy improves cognitive function in their children. We screened women with a singleton pregnancy before 20 weeks of gestation for subclinical hypothyroidism, defined as a thyrotropin level of 4.00 mU or more per liter and a normal free thyroxine (T 4 ) level (0.86 to 1.90 ng per deciliter [11 to 24 pmol per liter]), and for hypothyroxinemia, defined as a normal thyrotropin level (0.08 to 3.99 mU per liter) and a low free T 4 level (hypothyroidism underwent randomization at a mean of 16.7 weeks of gestation, and 526 with hypothyroxinemia at a mean of 17.8 weeks of gestation. In the subclinical hypothyroidism trial, the median IQ score of the children was 97 (95% confidence interval [CI], 94 to 99) in the levothyroxine group and 94 (95% CI, 92 to 96) in the placebo group (P=0.71). In the hypothyroxinemia trial, the median IQ score was 94 (95% CI, 91 to 95) in the levothyroxine group and 91 (95% CI, 89 to 93) in the placebo group (P=0.30). In each trial, IQ scores were missing for 4% of the children. There were no significant between-group differences in either trial in any other neurocognitive or pregnancy outcomes or in the incidence of adverse events, which was low in both groups. Treatment for subclinical hypothyroidism or hypothyroxinemia beginning between 8 and 20 weeks of gestation did not result in significantly better cognitive outcomes in children through 5 years of age than no treatment for those conditions.

Schizophrenia is a clinically heterogeneous disorder. A multifactorial structure of this syndrome has been described in previous reports. The aim of this study was to evaluate what are the possible diagnostic categories in patients having acute psychotic symptoms, studying their clinical characteristics in a cross-sectional study. An instrument for measuring psychotic symptoms was created using previous scales (SANS, SAPS, BPRS, EMUN, Zung depression scale). Using as criteria statistical indexes and redundance of items, the initial instrument having 101 items has been reduced to 57 items. 232 patients with acute psychotic symptoms, in most cases schizophrenia, attending Clínica Nuestra Señora de la Paz in Bogotá and Hospital San Juan de Dios in Chía have been evaluated from April, 2008 to December, 2009. Multivariate statistical methods have been used for analyzing data. A six-factor structure has been found (Deficit, paranoid-aggressive, disorganized, depressive, bizarre delusions, hallucinations). Cluster analysis showed eight subtypes that can be described as: 1) bizarre delusions-hallucinations; 2) deterioration and disorganized behavior; 3) deterioration; 4) deterioration and paranoid-aggressive behavior; 5) bizarre delusions; 6) paranoia-anxiety- aggressiveness; 7) depressive symptoms and bizarre delusions; 8) paranoia and aggressiveness with depressive symptoms These subtypes allow a more exhaustive characterization that those included in standard classification schemes and should be validated in longitudinal studies.

An association between white noise speech illusion and psychotic symptoms has been reported in patients and their relatives. This supports the theory that bottom-up and top-down perceptual processes are involved in the mechanisms underlying perceptual abnormalities. However, findings in nonclinical populations have been conflicting. The aim of this study was to examine the association between white noise speech illusion and subclinical expression of psychotic symptoms in a nonclinical sample. Findings were compared to previous results to investigate potential methodology dependent differences. In a general population adolescent and young adult twin sample (n = 704), the association between white noise speech illusion and subclinical psychotic experiences, using the Structured Interview for Schizotypy-Revised (SIS-R) and the Community Assessment of Psychic Experiences (CAPE), was analyzed using multilevel logistic regression analyses. Perception of any white noise speech illusion was not associated with either positive or negative schizotypy in the general population twin sample, using the method by Galdos et al. (2011) (positive: ORadjusted: 0.82, 95% CI: 0.6-1.12, p = 0.217; negative: ORadjusted: 0.75, 95% CI: 0.56-1.02, p = 0.065) and the method by Catalan et al. (2014) (positive: ORadjusted: 1.11, 95% CI: 0.79-1.57, p = 0.557). No association was found between CAPE scores and speech illusion (ORadjusted: 1.25, 95% CI: 0.88-1.79, p = 0.220). For the Catalan et al. (2014) but not the Galdos et al. (2011) method, a negative association was apparent between positive schizotypy and speech illusion with positive or negative affective valence (ORadjusted: 0.44, 95% CI: 0.24-0.81, p = 0.008). Contrary to findings in clinical populations, white noise speech illusion may not be associated with psychosis proneness in nonclinical populations.

Acculturation is the phenomenon that results when a group with one culture comes into continuous contact with a host culture. To investigate the correlation between acculturation and psychotic symptomatology in a group of immigrants suffering from psychosis and to explore differences in demographic factors related with the acculturation process between individuals with and without psychosis. Sixty-five patients and 317 non-psychotic immigrants were interviewed using the Immigrant Acculturation Scale (IAS) and a structured questionnaire for demographic data. The Positive and Negative Syndrome Scale (PANSS), the Calgary Depression Scale for Schizophrenia (CDSS) and the Global Assessment of Functioning (GAF) were also administered to all immigrants suffering from psychosis. Total IAS scores, as well as IAS everyday life scores, were positively correlated with GAF scores. IAS everyday life score in the patient group related with religion, marital status, gender and years in Greece, while in the non-psychosis group it was related with gender and years in Greece. IAS wishful orientation/nostos (the strong desire for one's homeland) related with religion in both groups. The IAS identity in the psychosis group did not show any significant relation with any of the variables, while in the non-patient group, it was related with marital status, gender and years in Greece. Age, duration of residence in Greece and higher adoption of Greek ethnic identity were the variables that differentiated the two groups of immigrants. Acculturation in immigrants suffering from psychosis could be seen as a process that does not correlate strongly with the severity of the symptomatology but is probably influenced by different set of factors.

Theorists from a variety of perspectives have asserted that obsessive compulsives are more risk-aversive, perfectionistic and guilt-ridden than non-obsessive compulsives, and that these characteristics are central features of the disorder. Furthermore, several have hypothesized that the parents of obsessive compulsives are characterized by risk-aversion, perfectionism, and high levels of criticism. Little research exists which corroborates these hypotheses, however. The present investigation examined these hypotheses among subclinical obsessive compulsives. In two different samples, subclinical obsessive compulsives were found to be more risk-aversive, perfectionistic, and guilt-ridden. Subclinical obsessive compulsives also perceived their parents to be more overprotective. The findings regarding other parental traits were less clear. There was some support for the hypothesis that the parents of subclinical obsessive compulsives are more risk-aversive, and that fathers are more critical and perfectionistic.

Pathways from Trauma to Psychotic Experiences: A Theoretically Informed Model of Posttraumatic Stress in Psychosis

Directory of Open Access Journals (Sweden)

Amy Hardy

2017-05-01

Full Text Available In recent years, empirical data and theoretical accounts relating to the relationship between childhood victimization and psychotic experiences have accumulated. Much of this work has focused on co-occurring Posttraumatic Stress Disorder or putative causal mechanisms in isolation from each other. The complexity of posttraumatic stress reactions experienced in psychosis remains poorly understood. This paper therefore attempts to synthesize the current evidence base into a theoretically informed, multifactorial model of posttraumatic stress in psychosis. Three trauma-related vulnerability factors are proposed to give rise to intrusions and to affect how people appraise and cope with them. First, understandable attempts to survive trauma become habitual ways of regulating emotion, manifesting in cognitive-affective, behavioral and interpersonal responses. Second, event memories, consisting of perceptual and episodic representations, are impacted by emotion experienced during trauma. Third, personal semantic memory, specifically appraisals of the self and others, are shaped by event memories. It is proposed these vulnerability factors have the potential to lead to two types of intrusions. The first type is anomalous experiences arising from emotion regulation and/or the generation of novel images derived from trauma memory. The second type is trauma memory intrusions reflecting, to varying degrees, the retrieval of perceptual, episodic and personal semantic representations. It is speculated trauma memory intrusions may be experienced on a continuum from contextualized to fragmented, depending on memory encoding and retrieval. Personal semantic memory will then impact on how intrusions are appraised, with habitual emotion regulation strategies influencing people’s coping responses to these. Three vignettes are outlined to illustrate how the model accounts for different pathways between victimization and psychosis, and implications for therapy are

Full Text Available OBJECTIVE: Hypothyroidism may cause neurologic signs and symptoms as its effects neuromuscular system like many other systems. Subclinical hypothyroidism is the most common thyroid dysfuntion, it may cause neuromuscular signs and symptoms. In this retrospective study, it is aimed to compare neuromuscular symptoms and electromyographic (EMG manifestations between hypothyroid patients and control group with normal thyroid function and without a disease causing polyneuropathy. METHODS: 31 overt hypothyroidic, 139 subclinic hypothyroidic patients and 50 individuals with normal thyroid function, without a disease causing polyneuropathy, as control group whom made EMG for another reason were included to the study. Neuromuscular symptoms, neurological examination and electrophysiological findings was obtained from the patient records. RESULTS: In our study, we observed frequent neuromuscular complaints such as fatigue, morning stiffness, cramp, general pain and paresthesia in favor of both for overt and subclinic hypothyroidism. Carpal Tunnel Syndrom(CTS, was statistically higher in overt hypothyroidism group than control group. CTS was also observed higher in subclinic hypothyroidism group when compared with control group but it didn't reach to statistical significance. We did not detect polyneuropathy in any group. Motor nerve velocity and compound muscle action potential amplitudes were found to be statistically significant difference between hypothyroid ve control group. CONCLUSION: Since motor fibres' and neuromuscular area's being affected in hypothyroidism, which we interpret to happen due to basal metabolism's slowing down, can show a significant recovery after thyroid replacement therapy. We consider that, in further studies, comparison of electrophysiological findings after treatment with the findings of pre -treatment is necessary

Koyanagi, Ai; Stickley, Andrew

2015-12-01

To assess the prevalence of sleep problems and their association with psychotic symptoms using a global database. Community-based cross-sectional study. Data were analyzed from the World Health Organization's World Health Survey (WHS), a population-based survey conducted in 70 countries between 2002 and 2004. 261,547 individuals aged ≥ 18 years from 56 countries. N/A. The presence of psychotic symptoms in the past 12 months was established using 4 questions pertaining to positive symptoms from the psychosis screening module of the Composite International Diagnostic Interview. Sleep problems referred to severe or extreme sleep problems in the past 30 days. Multivariable logistic regression was used to estimate the associations. The overall prevalence of sleep problems was 7.6% and ranged from 1.6% (China) to 18.6% (Morocco). Sleep problems were associated with significantly higher odds for at least one psychotic symptom in the vast majority of countries. In the pooled sample, after adjusting for demographic factors, alcohol consumption, smoking, and chronic medical conditions, having sleep problems resulted in an odds ratio (OR) for at least one psychotic symptom of 2.41 (95% confidence interval [CI] 2.18-2.65). This OR was 1.59 (1.40-1.81) when further adjusted for anxiety and depression. A strong association between sleep problems and psychotic symptoms was observed globally. These results have clinical implications and serve as a basis for future studies to elucidate the causal association between psychotic symptoms and sleep problems. © 2015 Associated Professional Sleep Societies, LLC.

Psychosomatic regularities of psychotic disorders of women in involution (pathogenesis, clinics, psychodynamic psychotherapy

Directory of Open Access Journals (Sweden)

2017-08-01

Full Text Available The problem of psychotic disorders with onset in the age of involution from broader perspective, guided by modern multidimensional paradigm, was never discussed before. Involutional psychosis is considered as a constellation of the biological changes that are irrefutable in this age period. Certain personality traits and coping strategies can be predisposing to psychotic response, as well as typical features of the “life curve” and external stressors that can run a psychotic reaction. The paper presents the result of our study. This study pays much attention to study of premorbid personality, with emphasis on characteristic features, peculiarities of the emotional reaction and motivation-behavioral area, which completely coincided with characteristics of the narcissistic personality disorder listed in DSM-V (2013. Aim: To explore the psychosomatic pathogenetic connections inherent involutionary psychosis, given pathogenic and pathoplastic impact of premorbid personality structure their syndromic form and dynamics, determine their place on the psychosomatic continuum and develop adequate and pathogenetic justified method of therapy. Methods. Data obtained by the clinical method were confirmed by the results of experimental psychological and neuropsychological researches. Results. Clinical characteristics of psychotic disorders in the patient population showed in the structure of psychosis the existence of two oppositely directed continuums: affective (depressive and delusional. This allows to allocate four main clinical forms of psychosis and their tendency to unite in two clusters that differed each other by the features, and also by their response to therapy and, therefore, by the prognosis. Conclusions: The psychodynamic approach to understanding the involutional psychosis, that was introduced by the author, got natural development in the proposed method of treatment that included complex medication and psychotherapy.

Context: Studies examining the association between subclinical hypothyroidism and mortality have yielded conflicting results. Emerging data suggest these associations may depend upon underlying congestive heart failure (CHF) and/or race, but this has not been empirically determined. Objective: Our objective was to examine the association between subclinical hypothyroidism and hypothyroidism overall with mortality according to pre-existing CHF and race. Design and Participants: We examined the associations of subclinical hypothyroidism (TSH higher than assay upper limit of normal; total T4 within reference) and hypothyroidism overall (TSH higher than assay upper limit of normal; total T4 below lower limit of normal or within reference) with all-cause mortality among Third National Health and Nutrition Examination Survey participants stratified by CHF and race using multivariable Cox models. To confirm whether differences between strata were statistically significant, we tested for interaction on the basis of CHF (separately) and race by likelihood ratio testing. Results: There were 14 130 (95.0%) euthyroid controls and 749 (5.0%) participants with hypothyroidism, 691 (4.6%) of whom had subclinical disease. Subclinical hypothyroidism vs euthyroidism was associated with greater mortality in those with CHF but not in those without: adjusted hazard ratios (HRs) (95% confidence intervals [CIs]) = 1.44 (1.01–2.06) and 0.97 (0.85–1.11), respectively (P interaction = .03). Similar findings were observed for hypothyroidism overall. Hypothyroidism overall vs euthyroidism was associated with greater mortality in Black participants (HR = 1.44 [95% CI = 1.03–2.03]) but not in non-Blacks (HR = 0.95 [95% CI = 0.83–1.08]) (P interaction = .03). Conclusion: Among participants with CHF, subclinical hypothyroidism and hypothyroidism overall are associated with greater death risk. Additional studies are needed to confirm findings and explore possible mechanisms for the

The phenomenology of the psychotic break and Huxley's trip: substance use and the onset of psychosis.

Nelson, Barnaby; Sass, Louis A

2008-01-01

While considerable research attention has been devoted to the causal relationship between substance use and psychosis, the phenomenology of the association between the two has largely been ignored. This is a significant shortcoming, because it blinds researchers to the possibility that there may be elements of the subjective experience of substance use and psychosis that contribute to their apparent relationship in empirical studies. The current paper examines the phenomenology of the onset of psychosis and the phenomenology of substance intoxication through consideration of two texts: Sass's account of the phenomenology of psychosis onset and Huxley's account of the experience of hallucinogenic intoxication. Sass's account of psychosis onset includes four components: Unreality, Fragmentation, Mere Being, and Apophany. The analysis reveals significant parallels - and also some differences - between this account and the phenomenology of substance intoxication. We discuss the implications of this for the causal relationship between psychosis and substance use and suggest several ways of understanding the overlapping phenomenologies. This includes the suggestion of a shared factor, perhaps best described as psychotic-like experience, which seems to involve a breakdown of the sign-referent relationship and relationship with the common-sense, practical world. However, in the onset of psychosis, this breakdown is primarily experienced as a sense of alienation from self and world, whereas in the hallucinogenic state a sense of mystical union and revelation seems predominant. Further research may extend this analysis by looking at experiences with other drugs, particularly cannabis, and by examining the phenomenology of psychotic disorder beyond the first episode.

MANAGEMENT OF ENDOCRINE DISEASE: Subclinical thyrotoxicosis: prevalence, causes and choice of therapy.

Science.gov (United States)

Carlé, Allan; Andersen, Stine Linding; Boelaert, Kristien; Laurberg, Peter

2017-06-01

Subclinical thyrotoxicosis is a condition affecting up to 10% of the population in some studies. We have reviewed literature and identified studies describing prevalences, causes and outcomes of this condition. Treatment should be considered in all subjects if this biochemical abnormality is persistent, especially in case of symptoms of thyrotoxicosis or in the presence of any complication. In particular, treatment should be offered in those subclinically thyrotoxic patients with a sustained serum TSH below 0.1 U/L. However it is important to recognise that there are no large controlled intervention studies in the field and thus there is no high quality evidence to guide treatment recommendations. In particular, there is no evidence for therapy and there is weak evidence of harm from thyrotoxicosis if serum TSH is in the 0.1-0.4 IU/L range. In this review, we describe the different causes of subclinical thyrotoxicosis, and how treatment should be tailored to the specific cause. We advocate radioactive iodine treatment to be the first-line treatment in majority of patients suffering from subclinical thyrotoxicosis due to multinodular toxic goitre and solitary toxic adenoma, but we do generally not recommend it as the first-line treatment in patients suffering from subclinical Graves' hyperthyroidism. Such patients may benefit mostly from antithyroid drug therapy. Subclinical thyrotoxicosis in early pregnancy should in general be observed, not treated. Moreover, we advocate a general restriction of therapy in cases where no specific cause for the presumed thyroid hyperactivity has been proven. © 2017 European Society of Endocrinology.

Late-night salivary cortisol is a frequently used and easily implemented diagnostically valuable test for the diagnosis of overt Cushing's syndrome. The use of late-night salivary cortisol in the diagnosis of subclinical Cushing's syndrome is somewhat controversial. In this study, we aimed to determine the diagnostic value of late-night salivary cortisol in diagnosing subclinical Cushing's syndrome and compare it with 24-hour urinary free cortisol levels (UFC). The study consisted of 33 cases of subclinical Cushing's syndrome, 59 cases of non-functioning adrenal adenoma, and 41 control subjects. Late-night salivary cortisol and UFC were measured in all the cases. The diagnosis of subclinical Cushing's syndrome was based on combined results of 1 mg dexamethasone suppression test > 1.8 μg/dL and ACTH Cushing's syndrome were significantly higher than in subjects with non-functioning adrenal adenoma and the control group (p Cushing's syndrome were determined as 82% and 60%, respectively. Using a cut-off value of 137 μg/day, the sensitivity and specificity of UFC was determined as 18% and 90%, respectively. Because the sensitivity of late-night salivary cortisol for the diagnosis of subclinical Cushing's syndrome is limited, using it as the sole screening test for subclinical Cushing's syndrome may lead to false negative results. However, using it as an adjunct test to other tests may be beneficial in the diagnosis of subclinical Cushing's syndrome. (Endokrynol Pol 2016; 67 (5): 487-492).

Background Data from prospective cohort studies regarding the association between subclinical hyperthyroidism and cardiovascular outcomes are conflicting. We aimed to assess the risks of total and coronary heart disease (CHD) mortality, CHD events, and atrial fibrillation (AF) associated with endogenous subclinical hyperthyroidism among all available large prospective cohorts. Methods Individual data on 52 674 participants were pooled from 10 cohorts. Coronary heart disease events were analyzed in 22 437 participants from 6 cohorts with available data, and incident AF was analyzed in 8711 participants from 5 cohorts. Euthyroidism was defined as thyrotropin level between 0.45 and 4.49 mIU/L and endogenous subclinical hyperthyroidism as thyrotropin level lower than 0.45 mIU/L with normal free thyroxine levels, after excluding those receiving thyroid-altering medications. Results Of 52 674 participants, 2188 (4.2%) had subclinical hyperthyroidism. During follow-up, 8527 participants died (including 1896 from CHD), 3653 of 22 437 had CHD events, and 785 of 8711 developed AF. In age-and sex-adjusted analyses, subclinical hyperthyroidism was associated with increased total mortality (hazard ratio [HR], 1.24, 95% CI, 1.06–1.46), CHD mortality (HR, 1.29; 95% CI, 1.02–1.62), CHD events (HR, 1.21; 95% CI, 0.99–1.46), and AF (HR, 1.68; 95% CI, 1.16–2.43). Risks did not differ significantly by age, sex, or preexisting cardiovascular disease and were similar after further adjustment for cardiovascular risk factors, with attributable risk of 14.5% for total mortality to 41.5% for AF in those with subclinical hyperthyroidism. Risks for CHD mortality and AF (but not other outcomes) were higher for thyrotropin level lower than 0.10 mIU/L compared with thyrotropin level between 0.10 and 0.44 mIU/L (for both, P value for trend, ≤.03). Conclusion Endogenous subclinical hyperthyroidism is associated with increased risks of total, CHD mortality, and incident AF, with highest

Measurement of sub-clinical atopic dermatitis (AD) is important for determining how long therapies should be continued after clinical clearance of visible AD lesions. An important biomarker of sub-clinical AD is epidermal hypertrophy, the structural measures of which often make optical coherence tomography (OCT) challenging due to the lack of a clearly delineated dermal-epidermal junction in AD patients. Alternatively, angiographic OCT measurements of vascular depth and morphology may represent a robust biomarker for quantifying the severity of clinical and sub-clinical AD. To investigate this, angiographic data sets were acquired from 32 patients with a range of AD severities. Deeper vascular layers within skin were found to correlate with increasing clinical severity. Furthermore, for AD patients exhibiting no clinical symptoms, the superficial plexus depth was found to be significantly deeper than healthy patients at both the elbow (p = 0.04) and knee (p<0.001), suggesting that sub-clinical changes in severity can be detected. Furthermore, the morphology of vessels appeared altered in patients with severe AD, with significantly different vessel diameter, length, density and fractal dimension. These metrics provide valuable insight into the sub-clinical severity of the condition, allowing the effects of treatments to be monitored past the point of clinical remission. PMID:29675335

Subclinical hyperthyroidism is defined as abnormal low TSH level with thyroid hormones within their reference range. This laboratory condition may be symptomatic in a relevant number of patients leading to tachycardia, sweating, nervousness, anxiety and insomnia. The risk for cardiovascular disease is increased with more frequent atrial fibrillation and increased left ventricular mass including diastolic dysfunction. Cardiovascular mortality and overall mortality surmounts the average of the normal population. Longterm TSH suppression leads to decreased bone mineral density and an increased fracture rate in the hip and in the spine. After evaluation of underlying causes, therapy should be considered, especially if TSH levels are below 0.1 mIU/l. © Georg Thieme Verlag KG Stuttgart · New York.

Full Text Available ABSTRACT: A lot of people live situations of mental sickness, from psychotic character, that can cause suffering both for the sick and his family. We believe that try this situation means to live with limitations and wearings in the familiar everyday, what makes difficult the living with the psychotic person. Considering these aspects, this research has the purpose of knowing the familiar perception about his living with a psychotic bearer person. It is about a qualitative, explorative and descriptive study, developed in a northwest city of Rio Grande do Sul state, called Ijuí. The people of the investigation are composed of five psychotic’s parents, which frequent the socioterapy group in Gloria district. The information collection happened trough open interviews, recorded and wrote out at all. The analysis of the obtained data followed MINAYO’s (2002 methodological proposition. By the contained information in the stud’s social actor’s declarations, emerged three thematic with a similar nucleus of thoughts. On first thematic, we discussed about the difficulties faced by the familiars in the living with the psychotic in the moment he has the acute symptoms. On the second thematic, we talked about the medical question as bring a therapeutic element that helps the mental sick to keep stable., becoming better the familiars life. The third thematic shows the family conception about mental sickness. With this research we concluded that the living with a mental sick person is taxing for the familiar and, sometimes, there are difficulties to understand the symptoms showed by the sick person. Besides that, the family considers the medication one of the most important possibilities of intervention in the psychotic’s therapy, what is reinforced by the health team that leads with these people.

Participation in mainstream education and employment facilitates both the recovery and the social inclusion of people with psychotic disorders. As part of the second Australian survey of psychosis, we assessed labour force activity and participation in formal education among working age adults with psychotic disorders. Data were drawn from a large national community prevalence survey of adults with psychotic disorders. Known as the Survey of High Impact Psychosis (SHIP), it was conducted in seven Australian catchment areas during March to December 2010. Current and past year labour force activity, current employment, past year participation in formal education and vocational training, and key clinical and demographic characteristics were examined in a sample of 1825 participants. Only 22.4% of people with psychotic disorders were found to be employed (either full-time or part-time) in the month prior to the survey. In the previous 12 months, 32.7% were employed at some time. Of those in competitive employment, the majority worked part-time (63.9%), while a quarter worked 38 or more hours per week (23.4%). In terms of educational attainment, 18.4% reported difficulties with reading or writing, while 31.9% completed high school, which represents 12 years of formal education. The proportion currently employed has remained stable at 22% since the last national survey in 1997. Policy makers and service providers could do more to ensure people with psychotic disorders obtain access to more effective forms of assistance with respect to both their continuing education and employment. More effective vocational and educational interventions for people with psychotic disorders appear to be urgently needed.

Patients suffering from psychotic disorders have an increased risk of comorbid somatic diseases such as cardiovascular disorders and diabetes mellitus. Doctor-related factors, such as unfamiliarity with these patients, as well as patient-related factors, such as cognitive disturbance and negative symptoms, contribute to suboptimal health care for these patients.General practitioners (GPs) could play a key role in diagnosing and treating this somatic comorbidity as in the Netherlands, almost all residents are registered at a general practice. This study aims to find out whether there are any differences between the levels of health care provided by GPs to patients with psychotic disorders, compared to other types of patients. A cohort of patients with an ICPC code of psychosis and two matched control groups, one consisting of patients with other mental problems and the other one of patients without any mental problems, were followed over a period of 5 years. Patients with psychotic disorders (N = 734) contacted the GP practice more often than patients in the control groups. These patients, both adults (p = 0.051) and the elderly (p 65 years old (p = 0.007). With regard to chronic illnesses, elderly psychosis patients had fewer contacts related to cardiovascular diseases or chronic lung diseases. Patients with psychotic disorders contact the GP practice more frequently than other types of patients. Adult psychosis patients with diabetes mellitus, cardiovascular diseases or chronic lung diseases receive the same amount of health care for these diseases as other primary care patients. The finding that older patients with psychotic disorders are diagnosed with cardiovascular diseases and obstructive lung diseases less frequently than other types of elderly patients requires further study.

Knowledge on the relationship between the autonomic nervous system and subclinical hyperthyroidism is mainly based upon cross-sectional studies in heterogeneous patient populations, and the effect of restoration to euthyroidism in subclinical hyperthyroidism has not been studied. We investigated the long-term effects of exogenous subclinical hyperthyroidism on the autonomic nervous system and the potential effects of restoration of euthyroidism. This was a prospective single-blinded, placebo-controlled, randomized trial. The study was performed at a university hospital. A total of 25 patients who were on more than 10-yr TSH suppressive therapy after thyroidectomy was examined. Patients were studied at baseline and subsequently randomized to a 6-month thyroid hormone substitution regimen to obtain either euthyroidism or maintenance of the subclinical hyperthyroid state. Urinary excretion of catecholamines and heart rate variability were measured. Baseline data of the subclinical hyperthyroidism patients were compared with data obtained in patients with hyperthyroidism and controls. Urinary excretion of norepinephrine and vanillylmandelic acid was higher in the subclinical hyperthyroidism patients compared with controls and lower compared with patients with overt hyperthyroidism. Heart rate variability was lower in patients with hyperthyroidism, intermediate in subclinical hyperthyroidism patients, and highest in the healthy controls. No differences were observed after restoration of euthyroidism. Long-term exogenous subclinical hyperthyroidism has effects on the autonomic nervous system measured by heart rate variability and urinary catecholamine excretion. No differences were observed after restoration to euthyroidism. This may indicate the occurrence of irreversible changes or adaptation during long-term exposure to excess thyroid hormone that is not remedied by 6-month euthyroidism.

Urban upbringing is associated with a 2-fold adulthood psychosis risk, and this association replicates for childhood psychotic symptoms. No study has investigated whether specific features of urban neighborhoods increase children's risk for psychotic symptoms, despite these early psychotic phenomena elevating risk for schizophrenia and other psychiatric disorders in adulthood. Analyses were conducted on over 2000 children from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally-representative cohort of UK-born twins. Neighborhood-level characteristics were assessed for each family via: a geodemographic discriminator indexing neighborhood-level deprivation, postal surveys of over 5000 residents living alongside the children, and in-home interviews with the children's mothers. Children were interviewed about psychotic symptoms at age 12. Analyses were adjusted for important family-level confounders including socioeconomic status (SES), psychiatric history, and maternal psychosis. Urban residency at age-5 (OR = 1.80, 95% CI = 1.16-2.77) and age-12 (OR = 1.76, 95% CI = 1.15-2.69) were both significantly associated with childhood psychotic symptoms, but not with age-12 anxiety, depression, or antisocial behavior. The association was not attributable to family SES, family psychiatric history, or maternal psychosis, each implicated in childhood mental health. Low social cohesion, together with crime victimization in the neighborhood explained nearly a quarter of the association between urbanicity and childhood psychotic symptoms after considering family-level confounders. Low social cohesion and crime victimization in the neighborhood partly explain why children in cities have an elevated risk of developing psychotic symptoms. Greater understanding of the mechanisms leading from neighborhood-level exposures to psychotic symptoms could help target interventions for emerging childhood psychotic symptoms. © The Author 2016.

Full Text Available Aim: Bovine mastitis and lameness are the most common production diseases affecting dairy farms worldwide resulting in huge economic impact and impaired animal welfare. The objective of this field study was to investigate the association of infectious and non-infectious claw disorders with the occurrence of subclinical intramammary infections (IMIs diagnosed by California mastitis test (CMT in dairy cows under Egyptian conditions. Materials and Methods: A total of 43 dairy cows were included in this field study. Subclinical IMI was diagnosed by CMT on all lactating quarters of cows. A cow was considered to have subclinical IMI if it had at least one subclinically infected quarter (=3. Cows were inspected carefully for claw disorders that recorded based on type and site. Locomotion and body condition scores were also recorded for each cow in addition to the limb affected. The association between the CMT and other explanatory variables was tested by Fisher's exact test. Results: The prevalence of infectious and non-infectious claw disorders was 81.4% (35/43 and 32.6% (14/43, respectively. Digital dermatitis (DD and heel horn erosion were the most prevalent infectious type with 79% (34/43 and 58% (25/43, respectively, while wall fissure was the most identified non-infectious one 11.6% (5/43. The prevalence of claw disorders in hind limbs was 88.4% (38/43 and 11.6% (5/43 in the forelimbs. Infectious claw disorders were significantly associated with the subclinical IMI diagnosed by CMT (p<0.05. Non-infectious claw affections, locomotion score, body condition score, and the affected limb had no association with the occurrence of subclinical IMI. Conclusion: DD is the highest prevalent claw disorder observed in dairy cows in Egypt. The hind limbs are more susceptible to claw disorders than the forelimbs. Infectious type of claw disorders is significantly associated with subclinical IMI diagnosed by CMT in dairy cows under Egyptian conditions indicating

Subclinical ketosis (SCK) is simply a condition marked by increased levels of circulating ketone bodies without the presence of the clinical signs of ketosis. Subclinical ketosis can cause economic losses through decreased milk production and association with preparturient diseases. Limited information is available regarding the prevalence of SCK in dairy herds in Southwestern Iran. The objectives of this study were (i) determination of the cutoff point of nonesterified fatty acids (NEFAs) and glucose concentrations for diagnosis of SCK using receiver operating characteristic (ROC) analysis, and (ii) determination of prevalence of subclinical ketosis in apparently healthy dairy cattle in Southwestern Iran. From October to December 2009, a total of 100 clinically healthy multiparous Holstein cows (3-8 years old) were randomly selected from 16 dairy herds around Kazerun, Fars Province, Iran. The cows had two-six lactations, with body weight ranging from 500 to 650 kg. Blood samples for each cow were taken at 2, 4 and 6 weeks post parturition and 3-4h after the morning feeding. The optimal cutoff point was set, by the ROC method, to >0.26 mmol/L for NEFA, and ketosis in all of the 2, 4 and 6 weeks postpartum. The results suggest that, a cut-off point of 0.26 mmol/L for NEFA concentrations can be used during early lactation for diagnosis of subclinical ketosis and making management decisions for prevention and treatment. Glucose cannot be a good criterion for diagnosis of SCK and it does not appear to be useful for monitoring subclinical ketosis. Copyright © 2011 Elsevier B.V. All rights reserved.

Childhood adversity has been associated with onset of psychosis in adulthood but these studies have used only general definitions of this environmental risk indicator. Therefore, we sought to explore the prevalence of more specific adverse childhood experiences amongst those with and without psychotic disorders using detailed assessments in a large epidemiological case-control sample (AESOP).

Lifetime Autism Spectrum Features in a Patient with a Psychotic Mixed Episode Who Attempted Suicide

2014-01-01

Full Text Available We present a case report of a young man who attempted suicide during a mixed episode with psychotic symptoms. The patient’s history revealed the lifetime presence of signs and features belonging to the autism spectrum realm that had been completely overlooked. We believe that this case is representative of an important and barely researched topic: what happens to children with nondiagnosed and nontreated subthreshold forms of autism when they grow old. The issue of early recognition of autism spectrum signs and symptoms is discussed, raising questions on the diagnostic boundaries between autism and childhood onset psychotic spectrums among patients who subsequently develop a full-blown psychotic disorder.

Individuals with schizophrenia have significant deficits in premorbid social and academic adjustment compared to individuals with non-psychotic diagnoses. However, it is unclear how severity and developmental trajectory of premorbid maladjustment compare across psychotic disorders. This study examined the association between premorbid functioning (in childhood, early adolescence, and late adolescence) and psychotic disorder diagnosis in a first-episode sample of 105 individuals: schizophrenia (n=68), schizoaffective disorder (n=22), and mood disorder with psychotic features (n=15). Social and academic maladjustment was assessed using the Cannon-Spoor Premorbid Adjustment Scale. Worse social functioning in late adolescence was associated with higher odds of schizophrenia compared to odds of either schizoaffective disorder or mood disorder with psychotic features, independently of child and early adolescent maladjustment. Greater social dysfunction in childhood was associated with higher odds of schizoaffective disorder compared to odds of schizophrenia. Premorbid decline in academic adjustment was observed for all groups, but did not predict diagnosis at any stage of development. Results suggest that social functioning is disrupted in the premorbid phase of both schizophrenia and schizoaffective disorder, but remains fairly stable in mood disorders with psychotic features. Disparities in the onset and time course of social dysfunction suggest important developmental differences between schizophrenia and schizoaffective disorder. Copyright © 2012 Elsevier B.V.

Full Text Available Insecure attachment styles have received theoretical attention and some initial empirical support as mediators between childhood adverse experiences and psychotic phenomena; however, further specificity needs investigating. The present interview study aimed to examine (i whether two forms of poor childhood care, namely parental antipathy and role reversal, were associated with subclinical positive and negative symptoms and schizophrenia-spectrum personality disorder (PD traits, and (ii whether such associations were mediated by specific insecure attachment styles.A total of 214 nonclinical young adults were interviewed for subclinical symptoms (Comprehensive Assessment of At-Risk Mental States, schizophrenia-spectrum PDs (Structured Clinical Interview for DSM-IV Axis II Disorders, poor childhood care (Childhood Experience of Care and Abuse Interview, and attachment style (Attachment Style Interview. Participants also completed the Beck Depression Inventory-II and all the analyses were conducted partialling out the effects of depressive symptoms.Both parental antipathy and role reversal were associated with subclinical positive symptoms and with paranoid and schizotypal PD traits. Role reversal was also associated with subclinical negative symptoms. Angry-dismissive attachment mediated associations between antipathy and subclinical positive symptoms and both angry-dismissive and enmeshed attachment mediated associations of antipathy with paranoid and schizotypal PD traits. Enmeshed attachment mediated associations of role reversal with paranoid and schizotypal PD traits.Attachment theory can inform lifespan models of how adverse developmental environments may increase the risk for psychosis. Insecure attachment provides a promising mechanism for understanding the development of schizophrenia-spectrum phenomenology and may offer a useful target for prophylactic intervention.

Subclinical hyperthyroidism is associated with adverse cardiovascular events, including stroke and atrial fibrillation. However, its impact on functional outcome after stroke remains unexplored. A total of 165 consecutively recruited patients admitted for ischemic stroke were included in this observational prospective study. Blood samples were taken in the morning within 3 days after symptom onset, and patients were divided into the following 3 groups: subclinical hyperthyroidism (0.1hyperthyroidism, and 23 patients (13.9%) had subclinical hypothyroidism. Patients with subclinical hyperthyroidism had a substantially increased risk of functional disability 3 months after stroke compared with subjects with euthyroid state (odds ratio, 2.63; 95% confidence interval, 1.02-6.82, adjusted for age, sex, smoking status, and time of blood sampling). The association remained significant, when including the baseline NIHSS, TIA, serum CRP, atrial fibrillation, body mass index, and total cholesterol as additional variables (odds ratio, 3.95; 95% confidence interval, 1.25-12.47), and was confirmed by the secondary outcome (Barthel Index: odds ratio, 9.12; 95% confidence interval, 2.08-39.89). Subclinical hyperthyroidism is a risk factor for poor outcome 3 months after ischemic stroke.

Objective: To explore the clinical significance of changes of serum bone metabolic biochemical markers levels in elderly subjects with subclinical hypothyroidism. Methods: Serum S-BGP (with RIA), TSH, FT 4 (with ECLIA), total cholesterol (TC), triglyceride (TG), HDL, LDL, ApoA 1 , ApoB and Ca 2+ (with biochemical methods) were measured in 30 elderly subjects with subclinical hypothyroidism and 30 controls. Results: The serum levels of S-BGP and calcium in elderly subjects with subclinical hypothyroidism (2.78 ± 0.96 μg/L and 2.16 ± 0.17 mmol/L respectively) were significantly lower than those in controls (3.9 ± 1.48 μg/L and 2.31 ± 0.21 mmol/L respectively, both P<0.01). TC and LDL levels in the subclinical hypothyroid subjects (5.58 ± 0.41 mmol/L and 3.67 ± 0.36 mmol/L) were significantly higher than those in controls (P<0.01). Conclusion: The lowering of calcium levels in subjects with subclinical hypothyroidism would lead to loss of bone mass. Decreased S-BGP contents might be the chief cause of osteoporosis in these subjects. (authors)

Background Grey matter, both volume and concentration, has been proposed as an endophenotype for schizophrenia given a number of reports of grey matter abnormalities in relatives of patients with schizophrenia. However, previous studies on grey matter abnormalities in relatives have produced inconsistent results. The aim of the present study was to examine grey matter differences between controls and siblings of patients with schizophrenia and to examine whether the age, genetic loading or subclinical psychotic symptoms of selected individuals could explain the previously reported inconsistencies. Methods We compared the grey matter volume and grey matter concentration of healthy siblings of patients with schizophrenia and healthy controls matched for age, sex and education using voxel-based morphometry (VBM). Furthermore, we selected subsamples based on age (< 30 yr), genetic loading and subclinical psychotic symptoms to examine whether this would lead to different results. Results We included 89 siblings and 69 controls in our study. The results showed that siblings and controls did not differ significantly on grey matter volume or concentration. Furthermore, specifically selecting participants based on age, genetic loading or subclinical psychotic symptoms did not alter these findings. Limitations The main limitation was that subdividing the sample resulted in smaller samples for the subanalyses. Furthermore, we used MRI data from 2 different scanner sites. Conclusion These results indicate that grey matter measured through VBM might not be a suitable endophenotype for schizophrenia. PMID:25768029

Community-based studies have linked psychotic experiences (PEs) with increased risks of suicidal thoughts and behaviors (STBs). However, it is not known if these associations vary across the life course or if mental disorders contribute to these associations. To examine the temporal association between PEs and subsequent STBs across the life span as well as the influence of mental disorders (antecedent to the STBs) on these associations. A total of 33 370 adult respondents across 19 countries from the World Health Organization World Mental Health Surveys were assessed for PEs, STBs (ie, ideation, plans, and attempts), and 21 DSM-IV mental disorders. Discrete-time survival analysis was used to investigate the associations of PEs with subsequent onset of STBs. Prevalence and frequency of STBs with PEs, and odds ratios and 95% CIs. Of 33 370 included participants, among those with PEs (n = 2488), the lifetime prevalence (SE) of suicidal ideation, plans, and attempts was 28.5% (1.3), 10.8% (0.7), and 10.2% (0.7), respectively. Respondents with 1 or more PEs had 2-fold increased odds of subsequent STBs after adjusting for antecedent or intervening mental disorders (suicidal ideation: odds ratio, 2.2; 95% CI, 1.8-2.6; suicide plans: odds ratio, 2.1; 95% CI, 1.7-2.6; and suicide attempts: odds ratio, 1.9; 95% CI, 1.5-2.5). There were significant dose-response relationships of number of PE types with subsequent STBs that persisted after adjustment for mental disorders. Although PEs were significant predictors of subsequent STB onset across all life stages, associations were strongest in individuals 12 years and younger. After adjustment for antecedent mental disorders, the overall population attributable risk proportions for lifetime suicidal ideation, plans, and attempts associated with temporally prior PEs were 5.3%, 5.7%, and 4.8%, respectively. Psychotic experiences are associated with elevated odds of subsequent STBs across the life course that cannot be

The period of subclinical signs that precedes the onset of psychosis is referred to as the prodrome or high-risk mental state. The "Symptom Onset in Schizophrenia (SOS) inventory" is an instrument to characterize and date the initial symptoms of a psychotic illness. The present study aims to provide reliability and validity data for clinical and research use of the Spanish version of the SOS. Thirty-six participants with a first-episode of psychosis meeting DSM-IV criteria for schizophrenia/schizoaffective/schizophreniform disorder were administered the translated SOS and other clinical assessments. The internal validity, intrarater and interrater reliability were studied. We found strong interrater reliability. To detect the presence/absence of prodromal symptoms, Kappa coefficients ranged between 0.8 and 0.7. Similarly, the raters obtained an excellent level of agreement regarding the onset of each symptom and the duration of symptoms until first treatment (intraclass correlation coefficients between 0.9 and 1.0). Cronbach's alpha was 0.9-1.0 for all the items. The interrater reliability and concurrent validity were also excellent in both cases. This study provides robust psychometric properties of the Spanish version of the SOS. The translated version is adequate in terms of good internal validity, intrarater and interrater reliability, and is as time-efficient as the original version. Copyright © 2017 Elsevier B.V.

2015-01-01

Discussion: The results are suggestive of more dispersed network communication in patients with psychotic disorder, with some evidence for trait-based network alterations in high-schizotypy individuals. Dispersed communication may contribute to the clinical phenotype in psychotic disorder. In addition, higher SMP may contribute to neuro- and social cognition, independent of psychosis risk.

Nicholas H Andrew

2014-01-01

Full Text Available Commotio retinae (CR is an outer retinal disorder following blunt trauma to the eye. Histologically it is characterized by disruption of the photoreceptor outer segments (OS, typically without injury to other retinal layers. Using spectral-domain optical coherence tomography (OCT the condition is visible as hyper-reflectivity of the OS. Most cases of CR are associated with transient grey-white discoloration of the retina and are easily diagnosed clinically, but there have been reports of OCT-confirmed CR without retinal discoloration. It is likely that this subclinical variant of CR is under-recognized as the OCT features of CR are subtle. Here, we report a case of OCT-confirmed subclinical CR that demonstrated prominent infrared hypo-reflectance, using the infrared protocol of the SPECTRALIS® OCT, Heidelberg Engineering. This case suggests that infrared reflectance may have a role in diagnosing cases of subclinical CR.

Full Text Available The factors determining the development or not of visceral leishmaniasis (VL have not been completely identified, but a Leishmania-specific cellular immune response seems to play a fundamental role in the final control of infection. Few studies are available regarding the production of cytokines in the subclinical form of VL, with only the production of IFN-g and TNF-a known. The aim of the present study was to identify immunological markers for the oligosymptomatic or subclinical form of VL. A prospective cohort study was conducted on 784 children aged 0 to 5 years from an endemic area in the State of Maranhão, Brazil, between January 1998 and December 2001. During 30 consecutive months of follow-up, 33 children developed the oligosymptomatic form of the disease and 12 the acute form. During the clinical manifestations, serum cytokine levels were determined in 27 oligosymptomatic children and in nine patients with the acute form using a quantitative sandwich enzyme immunoassay. In the subclinical form of VL, variable levels of IL-2 were detected in 52.3% of the children, IL-12 in 85.2%, IFN-g in 48.1%, IL-10 in 88.9%, and TNF-a in 100.0%, with the last two cytokines showing significantly lower levels than in the acute form. IL-4 was not detected in oligosymptomatic individuals. Multiple discriminant analysis used to determine the profile or combination of cytokines predominating in the subclinical form revealed both a Leishmania resistance (Th1 and susceptibility (Th2 profile. The detection of both Th1 and Th2 cytokine profiles explains the self-limited evolution accompanied by the discrete alterations observed for the subclinical form of VL.

Subclinical thyroid dysfunction is very common in clinical practice and there is some evidence that it may be associated with cardiovascular disease. The aim here was to evaluate the frequencies of subclinical thyroid disease and risk factors for cardiovascular disease among women at a workplace, and to evaluate the association between subclinical thyroid disease and cardiovascular risk factors among them. Cross-sectional study on 314 women aged 40 years or over who were working at Universidade de São Paulo (USP). All the women answered a questionnaire on sociodemographic characteristics and risk factors for cardiovascular disease and the Rose angina questionnaire. Anthropometric variables were measured and blood samples were analyzed for blood glucose, total cholesterol and fractions, high-sensitivity C-reactive protein, thyroid-stimulating hormone (TSH), free thyroxine (free-T4) and anti-thyroperoxidase antibodies (anti-TPO). The frequencies of subclinical hypothyroidism and hyperthyroidism were, respectively, 7.3% and 5.1%. Women with subclinical thyroid disease presented higher levels of anti-TPO than did women with normal thyroid function (P = 0.01). There were no differences in sociodemographic factors and cardiovascular risk factors according to thyroid function status, except for greater sedentarism among the women with subclinical hypothyroidism. Restricting the comparison to women with subclinical hypothyroidism (TSH > 10 mIU/l) did not change the results. In this sample of women, there was no association between poor profile of cardiovascular risk factors and presence of subclinical thyroid disease that would justify screening at the workplace.

A stepwise approach to the evaluation and treatment of subclinical hyperthyroidism.

Mai, Vinh Q; Burch, Henry B

2012-01-01

To review a stepwise approach to the evaluation and treatment of subclinical hyperthyroidism. English-language articles regarding clinical management of subclinical hyperthyroidism published between 2007 and 2012 were reviewed. Subclinical hyperthyroidism is encountered on a daily basis in clinical practice. When evaluating patients with a suppressed serum thyrotropin value, it is important to exclude other potential etiologies such as overt triiodothyronine toxicosis, drug effect, nonthyroidal illness, and central hypothyroidism. In younger patients with mild thyrotropin suppression, it is acceptable to perform testing again in 3 to 6 months to assess for persistence before performing further diagnostic testing. In older patients or patients with thyrotropin values less than 0.1 mIU/L, diagnostic testing should proceed without delay. Persistence of thyrotropin suppression is more typical of nodular thyroid autonomy, whereas thyroiditis and mild Graves disease frequently resolve spontaneously. The clinical consequences of subclinical hyperthyroidism, such as atrial dysrhythmia, accelerated bone loss, increased fracture rate, and higher rates of cardiovascular mortality, are dependent on age and severity. The decision to treat subclinical hyperthyroidism is directly tied to an assessment of the potential for clinical consequences in untreated disease. Definitive therapy is generally selected for patients with nodular autonomous function, whereas antithyroid drug therapy is more appropriate for mild, persistent Graves disease. The presented stepwise approach to the care of patients presenting with an isolated suppression of serum thyrotropin focuses on the differential diagnosis, a prediction of the likelihood of persistence, an assessment of potential risks posed to the patient, and, finally, a personalized choice of therapy.

To explore the lived experiences of patients with a psychotic or bipolar disorder and their families with emergency care during the first contact with a mobile crisis team. Open individual interviews were held with ten patients and ten family members. Content data-analysis was conducted. Communication and cooperation was difficult in several cases. Personal crisis plans were not always used. Stigma was felt, especially when police-assistance was needed. A calm, understanding attitude was appreciated. Focus explicitly on communication with the patient, despite the acute condition, enhances the chance of cooperation. Taking time for contact is important. © 2017 Wiley Periodicals, Inc.

Hypothesis: grandiosity and guilt cause paranoia; paranoid schizophrenia is a psychotic mood disorder; a review.

Science.gov (United States)

Lake, Charles Raymond

2008-11-01

Delusional paranoia has been associated with severe mental illness for over a century. Kraepelin introduced a disorder called "paranoid depression," but "paranoid" became linked to schizophrenia, not to mood disorders. Paranoid remains the most common subtype of schizophrenia, but some of these cases, as Kraepelin initially implied, may be unrecognized psychotic mood disorders, so the relationship of paranoid schizophrenia to psychotic bipolar disorder warrants reevaluation. To address whether paranoia associates more with schizophrenia or mood disorders, a selected literature is reviewed and 11 cases are summarized. Comparative clinical and recent molecular genetic data find phenotypic and genotypic commonalities between patients diagnosed with schizophrenia and psychotic bipolar disorder lending support to the idea that paranoid schizophrenia could be the same disorder as psychotic bipolar disorder. A selected clinical literature finds no symptom, course, or characteristic traditionally considered diagnostic of schizophrenia that cannot be accounted for by psychotic bipolar disorder patients. For example, it is hypothesized here that 2 common mood-based symptoms, grandiosity and guilt, may underlie functional paranoia. Mania explains paranoia when there are grandiose delusions that one's possessions are so valuable that others will kill for them. Similarly, depression explains paranoia when delusional guilt convinces patients that they deserve punishment. In both cases, fear becomes the overwhelming emotion but patient and physician focus on the paranoia rather than on underlying mood symptoms can cause misdiagnoses. This study uses a clinical, case-based, hypothesis generation approach that warrants follow-up with a larger representative sample of psychotic patients followed prospectively to determine the degree to which the clinical course observed herein is typical of all such patients. Differential diagnoses, nomenclature, and treatment implications are

The alterations in cortical morphology, such as cortical thinning, observed in psychotic disorder, may be the outcome of interacting genetic and environmental effects. It has been suggested that urban upbringing may represent a proxy environmental effect impacting cortical thickness (CT). Therefore, the current study examined whether the association between group as a proxy genetic variable (patients with psychotic disorder [high genetic risk], healthy siblings of patients [intermediate risk] and healthy control subjects [average risk]) and CT was conditional on different levels of the childhood urban environment and whether this was sex-dependent. T1-weighted MRI scans were acquired from 89 patients with a psychotic disorder, 95 non-psychotic siblings of patients with psychotic disorder and 87 healthy control subjects. Freesurfer software was used to measure CT. Developmental urban exposure was classified as low, medium, and high, reflecting the population density and the number of moves between birth and the 15th birthday, using data from the Dutch Central Bureau of Statistics and the equivalent database in Belgium. Multilevel regression analyses were used to examine the association between group, sex, and urban upbringing (as well as their interactions) and cortical CT as the dependent variable. CT was significantly smaller in the patient group compared to the controls (B = -0.043, p <0.001), but not in the siblings compared to the controls (B = -0.013, p = 0.31). There was no main effect of developmental urbanicity on CT (B = 0.001, p = 0.91). Neither the three-way group × urbanicity × sex interaction (χ2 = 3.73, p = 0.16), nor the two-way group × urbanicity interaction was significant (χ2 = 0.51, p = 0.77). The negative association between (familial risk for) psychotic disorder and CT was not moderated by developmental urbanicity, suggesting that reduced CT is not the outcome of familial sensitivity to the proxy environmental factor 'urban upbringing'.

O'Donoghue, Brian; Roche, Eric; Lane, Abbie

2016-07-01

The incidence of psychotic disorders varies according to the geographical area, and it has been investigated whether neighbourhood level factors may be associated with this variation. The aim of this systematic review is to collate and appraise the literature on the association between social deprivation and the incidence or risk for psychotic disorders. A systematic review was conducted, and studies were included if they were in English, provided a measure of social deprivation for more than one geographically defined area and examined either the correlation, rate ratio or risk of psychotic disorder. A defined search strategy was undertaken with Medline, CINAHL Plus and PsychInfo databases. A total of 409 studies were identified in the search, of which 28 fulfilled the inclusion criteria. Of these, four examined the association between social deprivation at the time of birth, three examined the putative prodrome of psychosis or those at ultra-high risk (UHR) for psychosis, and 23 examined the time at presentation with a first episode of psychosis (FEP) (one study examined two time points and one study included both UHR and FEP). Three of the studies that examined the level of social deprivation at birth found an association with a higher risk for psychotic disorders and increased social deprivation. Seventeen of the 23 studies found that there was a higher risk or rate of psychotic disorders in more deprived neighbourhoods at the time of presentation; however, adjusting for individual factors tended to weaken this association. Limited research has been conducted in the putative prodromal stage and has resulted in conflicting findings. Research conducted to date has not definitively identified whether the association is a result of social causation or social drift; however, the findings do have significant implications for service provision, such as the location and access of services.

Full Text Available Abstract Background Patients suffering from psychotic disorders have an increased risk of comorbid somatic diseases such as cardiovascular disorders and diabetes mellitus. Doctor-related factors, such as unfamiliarity with these patients, as well as patient-related factors, such as cognitive disturbance and negative symptoms, contribute to suboptimal health care for these patients. General practitioners (GPs could play a key role in diagnosing and treating this somatic comorbidity as in the Netherlands, almost all residents are registered at a general practice. This study aims to find out whether there are any differences between the levels of health care provided by GPs to patients with psychotic disorders, compared to other types of patients. Methods A cohort of patients with an ICPC code of psychosis and two matched control groups, one consisting of patients with other mental problems and the other one of patients without any mental problems, were followed over a period of 5 years. Results Patients with psychotic disorders (N = 734 contacted the GP practice more often than patients in the control groups. These patients, both adults (p = 0.051 and the elderly (p 65 years old (p = 0.007. With regard to chronic illnesses, elderly psychosis patients had fewer contacts related to cardiovascular diseases or chronic lung diseases. Conclusion Patients with psychotic disorders contact the GP practice more frequently than other types of patients. Adult psychosis patients with diabetes mellitus, cardiovascular diseases or chronic lung diseases receive the same amount of health care for these diseases as other primary care patients. The finding that older patients with psychotic disorders are diagnosed with cardiovascular diseases and obstructive lung diseases less frequently than other types of elderly patients requires further study.

Childhood abuse is considered one of the main environmental risk factors for the development of psychotic symptoms and disorders. However, this association could be due to genetic factors influencing exposure to such risky environments or increasing sensitivity to the detrimental impact of abuse. Therefore, using a large epidemiological case-control sample, we explored the interplay between a specific form of childhood abuse and family psychiatric history (a proxy for genetic risk) in the onset of psychosis. Data were available on 172 first presentation psychosis cases and 246 geographically matched controls from the Aetiology and Ethnicity of Schizophrenia and Other Psychoses study. Information on childhood abuse was obtained retrospectively using the Childhood Experience of Care and Abuse Questionnaire and occurrence of psychotic and affective disorders in first degree relatives with the Family Interview for Genetic Studies. Parental psychosis was more common among psychosis cases than unaffected controls (adjusted OR = 5.96, 95% CI: 2.09-17.01, P = .001). Parental psychosis was also associated with physical abuse from mothers in both cases (OR = 3.64, 95% CI: 1.06-12.51, P = .040) and controls (OR = 10.93, 95% CI: 1.03-115.90, P = .047), indicative of a gene-environment correlation. Nevertheless, adjusting for parental psychosis did not measurably impact on the abuse-psychosis association (adjusted OR = 3.31, 95% CI: 1.22-8.95, P = .018). No interactions were found between familial liability and maternal physical abuse in determining psychosis caseness. This study found no evidence that familial risk accounts for associations between childhood physical abuse and psychotic disorder nor that it substantially increases the odds of psychosis among individuals reporting abuse. © The Author 2014.

Cow serum proteome was evaluated by three different complementary approaches in the control group, subclinical and clinical mastitis in order to possibly find differential protein expression useful for a better understanding of the pathophysiology of mastitis as well as for an early diagnosis of the disease. The systemic inflammatory and oxidative stress response in cows with subclinical and clinical mastitis were observed. The collected evidence shows a differential protein expression of serpin A3-1, vitronectin-like protein and complement factor H in subclinical mastitis in comparison with the control. It was also found a differential protein expression of inter-alpha-trypsin inhibitor heavy chain H4, serpin A3-1, C4b-binding protein alpha chain, haptoglobin and apolipoprotein A-I in clinical mastitis compared to the control. Among the inflammatory proteins up-regulated in clinical mastitis, vitronectin is over-expressed in both subclinical and clinical mastitis indicating a strong bacterial infection. This suggests vitronectin as an important mediator in the pathogenesis of the onset of mastitis as well as a valuable marker for diagnosis of the subclinical form of the disease. Obtained data could be useful for the detection of mastitis during the subclinical phase and for a better comprehension of the pathophysiological mechanisms involved in the onset of the disease.

Subclinical hypothyroidism in the first trimester of pregnancy in North India

Directory of Open Access Journals (Sweden)

Jubbin Jagan Jacob

2013-01-01

Full Text Available Subclinical hypothyroidism based on population and trimester specific cut-offs is reported to complicate 1-2% of all pregnancies. Using the recent Endocrine Society guidelines of 2.5 mIU/L of Thyroid Stimulating Hormone as the upper level of normal in the first trimester the reported prevalence of subclinical hypothyroidism is much higher. Recent publications have also emphasized that there is considerable racial variation in the prevalence of thyroid disorders in pregnancy. Among published literature North Indian women appear to have the highest rates of subclinical hypothyroidism in the first trimester of pregnancy. More widespread use of universal screening and trimester specific ranges in pregnancy for thyroid hormonal assays will lead to a large number of North Indian women requiring treatment for thyroid disorders in pregnancy.

Prior research has found bidirectional associations between psychotic experiences (PEs) and selected substance use disorders. We aimed to extend this research by examining the bidirectional association between PEs and various types of substance use (SU) and substance use disorders (SUDs), and the influence of antecedent mental disorders on these associations. We used data from the World Health Organization World Mental Health surveys. A total of 30 902 adult respondents across 18 countries were assessed for (a) six types of life-time PEs, (b) a range of types of SU and DSM-IV SUDs and (c) mental disorders using the Composite International Diagnostic Interview. Discrete-time survival analyses based on retrospective age-at-onset reports examined the bidirectional associations between PEs and SU/SUDs controlling for antecedent mental disorders. After adjusting for demographics, comorbid SU/SUDs and antecedent mental disorders, those with prior alcohol use disorders [odds ratio (OR) = 1.6, 95% confidence interval (CI) = 1.2-2.0], extra-medical prescription drug use (OR = 1.5, 95% CI = 1.1-1.9), alcohol use (OR = 1.4, 95% CI = 1.1-1.7) and tobacco use (OR = 1.3, 95% CI = 1.0-1.8) had increased odds of subsequent first onset of PEs. In contrast, those with temporally prior PEs had increased odds of subsequent onset of tobacco use (OR = 1.5, 95% CI = 1.2-1.9), alcohol use (OR = 1.3, 95% CI = 1.1-1.6) or cannabis use (OR = 1.3, 95% CI = 1.0-1.5) as well as of all substance use disorders (ORs ranged between 1.4 and 1.5). There was a dose response relationship between both count and frequency of PEs and increased subsequent odds of selected SU/SUDs. Associations between psychotic experiences (PEs) and substance use/substance use disorders (SU/SUDs) are often bidirectional, but not all types of SU/SUDs are associated with PEs. These findings suggest that it is important to be aware of the presence of PEs within those with SUDs or at risk of SUDs

Several studies have suggested that lifetime cannabis consumption and childhood abuse synergistically contribute to the risk for psychotic disorders. This study aimed to extend existing findings regarding an additive interaction between childhood abuse and lifetime cannabis use by investigating the moderating role of type and frequency of cannabis use. Up to 231 individuals presenting for the first time to mental health services with psychotic disorders and 214 unaffected population controls from South London, United Kingdom, were recruited as part of the Genetics and Psychosis study. Information about history of cannabis use was collected using the Cannabis Experiences Questionnaire. Childhood physical and sexual abuse was assessed using the Childhood Experience of Care and Abuse Questionnaire. Neither lifetime cannabis use nor reported exposure to childhood abuse was associated with psychotic disorder when the other environmental variable was taken into account. Although the combination of the two risk factors raised the odds for psychosis by nearly three times (adjusted OR = 2.94, 95% CI: 1.44-6.02, P = 0.003), no evidence of interaction was found (adjusted OR = 1.46, 95% CI: -0.54 to 3.46, P = 0.152). Furthermore, the association of high-potency cannabis and daily consumption with psychosis was at least partially independent of the effect of childhood abuse. The heavy use of high-potency cannabis increases the risk of psychosis but, in addition, smoking of traditional resin (hash) and less than daily cannabis use may increase the risk for psychosis when combined with exposure to severe childhood abuse. © 2015 Wiley Publishing Asia Pty Ltd.

This study tested the hypothesis that the presence and characteristics of naturally occurring involuntary imagery would be related to poorer context-dependent spatial memory and higher levels of proneness to psychotic experiences. Poorer contextual memory was also predicted to be associated with a greater sense of "nowness". Participants completed a virtual environment task that assessed contextual memory through responses that required allocentric and egocentric processing of virtual stimuli. Two questionnaires assessing predisposition to psychotic experiences were employed. Finally, participants completed an interview that required details of recent, naturally occurring involuntary images. Reports of involuntary imagery were associated with greater proneness to psychotic experiences but not with memory. In those participants who reported imagery, however, poorer memory performance was associated with more vivid and detailed intrusive imagery. Poorer contextual memory was specifically associated with a greater sense of "nowness". Possible links between contextual memory and proneness to psychosis are discussed.

Previous work has identified associations between psychotic experiences (PEs) and general medical conditions (GMCs), but their temporal direction remains unclear as does the extent to which they are independent of comorbid mental disorders. In total, 28 002 adults in 16 countries from the WHO World Mental Health (WMH) Surveys were assessed for PEs, GMCs and 21 Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM-IV) mental disorders. Discrete-time survival analyses were used to estimate the associations between PEs and GMCs with various adjustments. After adjustment for comorbid mental disorders, temporally prior PEs were significantly associated with subsequent onset of 8/12 GMCs (arthritis, back or neck pain, frequent or severe headache, other chronic pain, heart disease, high blood pressure, diabetes and peptic ulcer) with odds ratios (ORs) ranging from 1.3 [95% confidence interval (CI) 1.1-1.5] to 1.9 (95% CI 1.4-2.4). In contrast, only three GMCs (frequent or severe headache, other chronic pain and asthma) were significantly associated with subsequent onset of PEs after adjustment for comorbid GMCs and mental disorders, with ORs ranging from 1.5 (95% CI 1.2-1.9) to 1.7 (95% CI 1.2-2.4). PEs were associated with the subsequent onset of a wide range of GMCs, independent of comorbid mental disorders. There were also associations between some medical conditions (particularly those involving chronic pain) and subsequent PEs. Although these findings will need to be confirmed in prospective studies, clinicians should be aware that psychotic symptoms may be risk markers for a wide range of adverse health outcomes. Whether PEs are causal risk factors will require further research.

To describe from the perspective of people living with psychotic illness their use of general practitioner services over a 12-month period and the experiences, attitudes and challenges general practitioners face providing health care to this population. A two-phase design was used. Phase 1, screening for psychosis, occurred in public specialised mental health services and non-government organisations within seven catchment sites across Australia. In Phase 2, 1825 people who were screened positive for psychosis were randomly selected for interview which included questions about frequency and reason for general practitioner contact in the 12 months prior to interview. General practitioners (1473) of consenting participants were also surveyed. Almost all (90.3%) survey participants had consulted a general practitioner in the 12-month period, on average 8.9 times, and 28.8% of attenders had consulted 12 times or more. The majority (83.5%) attended one general practitioner practice. Most (77.6%) general practitioners wanted to be involved in the mental health care of their patient. Although 69.1% said the management of their patient was not problematic for their practice, one in five general practitioners reported issues related to patient non-compliance with treatment and non-attendance at scheduled appointments; time constraints; and lack of feedback from treating mental health services. People with psychotic disorders consult general practitioners, some very frequently. Most Australian general practitioners believe they have a responsibility to review the physical and mental health of their patients. Improved communication between general practitioners and mental health services, and easier access to mental health support, may help general practitioners manage the complex mental, physical and social problems of their patients.

Full Text Available Plasma samples were collected from healthy as well as clinical and sub-clinical mastitis affected cows from Barasat, West Bengal, India. Plasma samples, after ammonium sulphate precipitation, were dialyzed against several changes of PBS (pH 7.2 to remove the excess ammonium sulphate. Then plasma fibrinogens were purified by gel filtration chromatography on Sephacryl S-200 HR. SDS-PAGE (10% of purified fibrinogen from plasma of healthy cow revealed polypeptide bands of 74, 67 and 57 kDa which represent the α (alpha, β (beta and γ (gamma- chains respectively. On the other hand, purified fibrinogen from plasma of sub-clinical and clinical mastitis affected cow revealed polypeptide bands of 73 (α-chain, 68 kDa (β-chain and 72 (γ-chain, 68 kDa (β-chain respectively. The SDS-PAGE analysis showed the absence of gamma (γ- chain of fibrinogen in both the samples of sub-clinical and clinical mastitis positive cow. Single precipitin line was observed in double immunodiffusion test when purified fibrinogen from healthy, clinical and subclinical mastitis positive cows reacted with hyper immune sera raised in rabbit. No precipitin line was found against the normal control serum. These purified fibrinogens also showed cross reactivity against antibody raised in rabbit when analyzed by western blot technique.

Objective: To study the incidence and etiology of subclinical thyroid function disorders in 12592 subjects tested. Methods: The etiology of 874 patients with abnormal serum TSH (with IRMA) found in the tested 12592 patients, whose serum T 3 , T 4 , FT 3 , FT 4 , TSH, TGA and TMA were also detected with RIA was analyzed. Results: 874 of 12592 patients had abnormal TSH levels (6.94%). Among them, TSH was elevated in 397 patients (3.15%) and decreased in 477 patients (3.79%). Most of them were associated with obvious related thyroid or other thronic diseases such as hyperthyroidism after therapy, thyroxine replacement treatment of hypothyroidism and other thyroid diseases (thyroiditis, diffuse nontoxic goiter). In the remaining apparently disease-free 143 subjects, there were with subclinical hypothyroidism and 34 (3.89% of 874) with subclinical hyperthyroidism. Also among the 874 patients, 30.78% (n=269) patients had elevated TGA and TMA[16.82% (n=147) had elevated TSH and TGA, TMA simultaneously, 13.96% (n=122) had decreased TSH and elevated TGA and TMA simultaneously]. In the 874 patients, 256 (29.29%) were older than 60. Conclusion: Elderly people has higher incidence of subclinical thyroid function disorders. We should pay more attention to the detection of this condition, especially in elderly patients. (authors)

Aspects of Piaget's cognitive developmental psychology and neurobiology of psychotic disorders - an integrative model.

2008-09-01

Psychological, neurobiological and neurodevelopmental approaches have frequently been used to provide pathogenic concepts on psychotic disorders. However, aspects of cognitive developmental psychology have hardly been considered in current models. Using a hypothesis-generating approach an integration of these concepts was conducted. According to Piaget (1896-1980), assimilation and accommodation as forms of maintenance and modification of cognitive schemata represent fundamental processes of the brain. In general, based on the perceived input stimuli, cognitive schemata are developed resulting in a conception of the world, the realistic validity and the actuality of which is still being controlled and modified by cognitive adjustment processes. In psychotic disorders, however, a disproportion of environmental demands and the ability to activate required neuronal adaptation processes occurs. We therefore hypothesize a failure of the adjustment of real and requested output patterns. As a consequence autonomous cognitive schemata are generated, which fail to adjust with reality resulting in psychotic symptomatology. Neurobiological, especially neuromodulatory and neuroplastic processes play a central role in these perceptive and cognitive processes. In conclusion, integration of cognitive developmental psychology into the existing pathogenic concepts of psychotic disorders leads to interesting insights into basic disease mechanisms and also guides future research in the cognitive neuroscience of such disorders.

Full Text Available Shared psychotic disorder or folie à deux is a rare and relatively unknown syndrome. Large case series are needed to find out and clarify the etiological factors and the phenomenology of shared psychotic disorder by comparing the cases from different society and cultures. In this study, we reviewed all reported cases of shared psychotic disorder that had been published or presented in Turkey since 1962. To reach this aim, we have searched Pubmed/Medline, ScienceDirect, Google Scholar, Ulakbim Turkish Medical Index, Turkish Psychiatric Index databases for published records originating from Turkey. We have also manually searched poster abstract books of congresses held in Turkey between 1962 and 2009. All cases eligible for inclusion into this study have been evaluated one by one and grouped as primary or secondary cases. The features of these cases were investigated for a number of variables including age, sex, educational level, occupation, the presence of shared delusion and hallucinations, diagnosis, management, onset of illness, family history, IQ, social isolation, the nature of the relationship and classification system used for diagnosis. The results have showed that the syndrome is more frequently observed among women, within same family members and between sisters. Social isolation was the most common risk factor in these patients and most patients shared hallucinations with their partners along with their delusions. Several secondary cases required antipsychotic drugs for the treatment of their symptoms. Though these features were inline with literature findings, the present findings from Turkish population were different from previous studies with regards to the presence of olfactory hallucinations, absence of grandiose delusions and the number of affected family members. The results mostly supported the challenges and discussions in western countries. To understand this most pathological form of interpersonal relationships

The examination of potential roles of epigenetic alterations in the pathogenesis of psychotic diseases have become an essential alternative in recent years as genetic studies alone are yet to uncover major gene(s) for psychosis. Here, we describe the current state of knowledge from the gene-specific and genome-wide studies of postmortem brain and blood cells indicating that aberrant DNA methylation, histone modifications and dysregulation of micro-RNAs are linked to the pathogenesis of mental diseases. There is also strong evidence supporting that all classes of psychiatric drugs modulate diverse features of the epigenome. While comprehensive environmental and genetic/epigenetic studies are uncovering the origins, and the key genes/pathways affected in psychotic diseases, characterizing the epigenetic effects of psychiatric drugs may help to design novel therapies in psychiatry.

Full Text Available Background/Aim. The Fracture Risk Assessment Tool (FRAX® score is the 10-year estimated risk calculation tool for bone fracture that includes clinical data and hip bone mineral density measured by dual-energy x-ray absorptiometry (DXA. The aim of this cross-sectional study was to elucidate the ability of the FRAX® score in discriminating between bone fracture positive and negative pre- and post-menopausal women with subclinical hyperthyroidism. Methods. The bone mineral density (by DXA, thyroid stimulating hormone (TSH level, free thyroxine (fT4 level, thyroid peroxidase antibodies (TPOAb titre, osteocalcin and beta-cross-laps were measured in 27 pre- and post-menopausal women with newly discovered subclinical hyperthyroidism [age 58.85 ± 7.83 years, body mass index (BMI 27.89 ± 3.46 kg/m2, menopause onset in 46.88 ± 10.21 years] and 51 matched euthyroid controls (age 59.69 ± 5.72 years, BMI 27.68 ± 4.66 kg/m2, menopause onset in 48.53 ± 4.58 years. The etiology of subclinical hyperthyroisims was autoimmune thyroid disease or toxic goiter. FRAX® score calculation was performed in both groups. Results. In the group with subclinical hyperthyroidism the main FRAX® score was significantly higher than in the controls (6.50 ± 1.58 vs 4.35 ± 1.56 respectively; p = 0.015. The FRAX® score for hip was also higher in the evaluated group than in the controls (1.33 ± 3.92 vs 0.50 ± 0.46 respectively; p = 0.022. There was no correlations between low TSH and fracture risk (p > 0.05. The ability of the FRAX® score in discriminating between bone fracture positive and negative pre- and postmenopausal female subjects (p < 0.001 is presented by the area under the curve (AUC plotted via ROC analysis. The determined FRAX score cut-off value by this analysis was 6%, with estimated sensitivity and specificity of 95% and 75.9%, respectively. Conclusion. Pre- and postmenopausal women with subclinical hyperthyroidism have higher FRAX® scores and thus

Subclinical hypothyroidism can be defined as an asymptomatic state in which a reduction in thyroid activity has been compensated by an increased TSH output to maintain an euthyroid state. We analysed clinical features, laboratory data, and pathologic findings in 39 cases of subclinical hypothyroidism who were diagnosed at the Dept. of Internal Medicine, Chungnam National University Hospital from Aug. 1984 to June, 1985. 1) The age distribution was from sixteen to sixty-nine and mean age was 34.8. Peak incidence was in the 4th decade and 3rd, 5th, 6th decade in order. 2) The sex distribution showed female preponderance with a ratio of 18.5 to 1. 3) The major presenting manifestations were nonspecific ones such as fatigue, indigestion, and anorexia. 4) Physical examination revealed diffuse goiter in 47.6%. Major abnormalities were no gross abnormality (30.9%), nodular goiter and facial edema. 5) There was no significant difference of the basal serum T3 and T4 concentrations between subclinical hypothyroidism and normal controls (p>0.05). 6) The basal serum TSH concentration of subclinical hypothyroidism (32.61±14.95 μU/ml) was significantly higher than that of normal controls (3.92±1.05 μU/ml) (p<0.005). 7) Microsomal antibody was detected in 80.6% and thyroglobulin antibody was detected in 30%. 8) The pathologic findings in 26 cases revealed Hashimoto's thyroiditis in 76.9% (lymphocytic type, 34.6%; oxyphilic type, 26.9%; fibrotic type, 15.4%). The others were adenomatous goiter (15.4%), adenomatous carcinoma (3.8%) and subacute thyroiditis (3.8%).

The purpose of this study was to test the reliability, validity, and factor structure of a Chinese version of the Psychotic Symptom Rating Scale (PSYRATS) in 198 and 202 adult patients with recent-onset and chronic psychosis, respectively. The PSYRATS has been translated into different language versions and has been validated for clinical and research use mainly in chronic psychotic patients but not in recent-onset psychosis patients or in Chinese populations. The psychometric analysis of the translated Chinese version included assessment of its content validity, semantic equivalence, interrater and test-retest reliability, reproducibility, sensitivity to changes in psychotic symptoms, internal consistency, concurrent validity (compared to a valid psychotic symptom scale), and factor structure. The Chinese version demonstrated very satisfactory content validity as rated by an expert panel, good semantic equivalence with the original version, and high interrater and test-retest (at 2-week interval) reliability. It also indicated very good reproducibility of and sensitivity to changes in psychotic symptoms in line with the symptom severity measured with the Positive and Negative Syndrome Scale (PANSS). The scale consisted of four factors for the hallucination subscale and two factors for the delusion subscale, explaining about 80% of the total variance of the construct, indicating satisfactory correlations between the hallucination and delusion factors themselves, between items, factors, subscales, and overall scale, and between factors and relevant item and subscale scores of the PANSS. The Chinese version of the PSYRATS is a reliable and valid instrument to measure symptom severity in Chinese psychotic patients complementary to other existing measures mainly in English language.

The association between subclinical hypothyroidism and cardiovascular disease and the beneficial effect of levothyroxine replacement in subclinical hypothyroidism are still under debate. The present study was designed to determine whether subclinical hypothyroidism is associated with an increase in the intima-media thickness of the common carotid artery (C-IMT) and whether thyroid hormone replacement can reverse this change in the C-IMT. Patients with newly-diagnosed subclinical (n=36) and overt (n=40) hypothyroidism and healthy euthyroid individuals (n=32) participated in this study. All the patients were examined for clinical characteristics, and the serum lipid levels and the C-IMT were measured. Patients with subclinical hypothyroidism had a C-IMT measurement after 18 months of levothyroxine replacement. There were meaningful differences in total cholesterol and LDL-cholesterol levels between patients with subclinical hypothyroidism and euthyroidism. The subjects with subclinical and overt hypothyroidism had a greater C-IMT compared with euthyroid controls (0.66+/- 0.10 and 0.70+/- 0.11 vs. 0.57+/- 0.08 mm, respectively; P replacement significantly decreased the C-IMT (0.67+/- 0.11 to 0.60+/- 0.10 mm; P = 0.021) and improved the lipid profile. Based on multiple regression analysis, the decrement in LDL-cholesterol was independently associated with the regression of the C-IMT. Subclinical hypothyroidism was closely related to an increased C-IMT. Thyroid hormone replacement resulted in regression of the increased C-IMT, which was attributed to the improvement in the lipid profile.

Feasibility and Efficacy of Prolonged Exposure for PTSD among Individuals with a Psychotic Spectrum Disorder

Full Text Available Objective: Few empirical studies have examined the feasibility of trauma-focused treatment among individuals with schizophrenia. This lack of research is important given the substantial overlap of trauma exposure and subsequent PTSD with psychotic spectrum disorders, and the potential for PTSD to complicate the course and prognosis of schizophrenia and other variants of severe mental illness.Method: As part of a larger study, 14 veterans with a psychotic spectrum disorder were enrolled to receive prolonged exposure (PE for PTSD within a single arm open trial study design. Patient reactions and responses to PE were examined using feasibility indices such as attrition, survey reactions, and treatment expectancy; pre and post-changes in PTSD severity and diagnostic status; and thematic interviews conducted post-intervention.Results: Quantitative and qualitative data indicate that implementation of PE is feasible, subjectively well-tolerated, and may result in clinically significant reductions in PTSD symptoms in patients with psychotic spectrum disorders.Conclusion: Consistent with treatment outcome data in clinical populations with a broader range of severe mental illnesses, the current results support the use of PTSD exposure-based interventions, such as PE, for individuals with psychotic spectrum disorders.

The prevalence of psychosis and needs for care among homeless people were studied in inner Melbourne. This was a two-stage nested study within the Australian National Survey of People Living with Psychotic Illness. A screen for psychosis was administered to a representative sample of men and women living in marginal housing in a mental health service catchment area. A selected subsample of 82 screen-positive respondents was interviewed using the Diagnostic Interview for Psychosis (DIP), a semistructured, standardized interview with three modules: (i) demography, functioning and quality of life; (ii) diagnosis; and (iii) service use. An unexpectedly high prevalence of people living with psychotic disorders (estimated lifetime prevalence 42%, 95% CI=37-47%) may reflect a concentration of vulnerable people in the shrinking marginal housing supply in the inner city areas. Disability in everyday, occupational and social functioning is greater for this subgroup than for other people living with psychosis in Australia. Most people were single and unemployed, and many reported social isolation and feeling unsafe. Substance use disorders were common. Most people were using health services, including specialist mental health services, but few were receiving rehabilitation, vocational or housing support. Despite high levels of contact with a well-organized, sectorized mental health service in an affluent country, this pocket of several hundred people had high levels of persisting disability and needs. The literature and local experience suggest that changing this situation is likely to require co-ordinated policy and practice between the health, welfare and housing sectors.

To evaluate the association of diabetic retinopathy with subclinical atherosclerosis in middle-aged and elderly Chinese with type 2 diabetes. A cross-sectional community-based study was performed among 1607 patients aged 40 years or older in Shanghai. Non-mydriatic digital fundus photography examination was used in diabetic retinopathy detection. Presence of elevated carotid intima-media thickness or carotid plaque was defined as subclinical atherosclerosis. The prevalence of diabetic retinopathy was 15.1% in total patients. Patients with diabetic retinopathy were more likely to have elevated carotid intima-media thickness, carotid plaque and subclinical atherosclerosis than those without diabetic retinopathy (37.9% vs 30.7%, 57.6% vs 49.6% and 64.6% vs 57.1%, respectively). The presence of diabetic retinopathy was significantly associated with increased odds of subclinical atherosclerosis (odds ratio = 1.93, 95% confidence interval = 1.03-3.60) after full adjustments. The presence of diabetic retinopathy was significantly associated with subclinical atherosclerosis in middle-aged and elderly patients with type 2 diabetics in China. © The Author(s) 2015.

Selenium (Se) participates in several enzymatic reactions necessary for regulating the homeostasis of thyroid hormones. We aimed to analyze the association between dietary Se intake and subclinical hypothyroidism. Baseline data from the Longitudinal Study of Adult Health (Estudo Longitudinal de Saúde do Adulto-ELSA-Brasil) in Brazil were analyzed, with a final sample size of 14,283 employees of both sexes aged 35⁻74 years. Dietary data was collected using a previously validated food frequency questionnaire. Subclinical hypothyroidism was categorized as thyroid-stimulating hormone levels of >4.0 IU/mL and free prohormone thyroxine levels within normal limits, without administering drugs for thyroid disease. A multiple logistic regression model was used to assess the relationship between the presence of subclinical hypothyroidism and tertiles of Se consumption. The prevalence of subclinical hypothyroidism in the study sample was 5.4% (95% confidence interval [CI], 3.8⁻7.0%). Compared with the first tertile of Se intake, the second (odds ratio [OR], 0.79; 95% CI, 0.65⁻0.96%) and third (OR, 0.72; 95% CI, 0.58⁻0.90%) tertiles were inversely associated with subclinical hypothyroidism, however further research is needed to confirm the involvement of Se in subclinical hypothyroidism using more accurate methodologies of dietary assessment and nutritional status to evaluate this relationship.

Substances such as alcohol, cocaine, amphetamine, and cannabis can produce psychotic reactions in individuals who are otherwise free of serious mental illness. However, persons with primary psychotic disorders, such as schizophrenia and bipolar disorder, who use these substances often present for treatment with signs and symptoms similar to those whose psychosis resulted from the use of drugs alone. While it is often difficult to distinguish substance-induced from primary psychoses, especially early in the course of treatment, this differential diagnosis has important implications for treatment planning. To help clinicians distinguish these two types of presentations, the authors first review the types of psychotic symptoms that can co-occur with substance use. They discuss the prevalence and patterns of substance use that have been found in patients with schizophrenia and other primary psychotic disorders and review the negative outcomes associated with substance use in this population. The prevalence of and types of symptoms and problems associated with psychotic symptoms that occur as a result of substance use alone are also reviewed. The authors describe assessment procedures for differentiating substance-induced and primary psychotic disorders. They stress the importance of accurately establishing the temporal relationship between the substance use and the onset and continuation of psychotic symptoms in making a differential diagnosis, as well as the importance of being familiar with the types of psychological symptoms that can occur with specific substances. The authors review the utility and limitations of a number of diagnostic instruments for assessing patients with co-occurring psychosis and substance use problems, including The Addiction Severity Index, The Michigan Alcohol Screening Test, and diagnostic interviews such as the Schedule for Affective Disorders and Schizophrenia and the Structured Clinical Interview for DSM. They then discuss the

Subclinical hypothyroidism in childhood.

LENUS (Irish Health Repository)

O'Grady, M J

2012-02-01

Subclinical hypothyroidism (SH) is defined as an elevated thyroid stimulating hormone (TSH) in association with a normal total or free thyroxine (T4) or triiodothyronine (T3). It is frequently encountered in both neonatology and general paediatric practice; however, its clinical significance is widely debated. Currently there is no broad consensus on the investigation and treatment of these patients; specifically who to treat and what cut-off level of TSH should be used. This paper reviews the available evidence regarding investigation, treatments and outcomes reported for childhood SH.

Ecstasy use is generally chosen by adolescents and young adults for its entactogenic properties (the production of feelings of empathy, love, and emotional closeness to others.) Despite this desired and frequently realized outcome, Ecstasy use has often resulted in the genesis of psychotic symptoms and aggressive behaviors, particularly after chronic and/or intensive use. To explore the negative consequences of Ecstasy use and to examine the aggressive nature oftentimes seen in many Ecstasy users we employed a case-control study model. We compared, by means of validated psychometric tests, the psychopathological symptoms (BPRS), the aggressiveness (OAS) and the social adjustment (DSM-GAF) of psychotic patients with (n = 23) and without (n = 46) recent user of Ecstasy, during their first psychotic episode and hospitalization. All 23 Ecstasy users were Ecstasy users only. Almost all of the psychotic symptoms were of similar severity in both groups. Blunted affect was milder in users than in non-users, whereas hostility and aggressive behavior was significantly more severe in users than in non-users. psychosis with a high level of aggressiveness and violence constitutes an important 'side-effect' that surely runs counter to the expected entactogenic action of Ecstasy. At a patient psycho-educational level, this study suggests that the use of Ecstasy may be counterproductive with respect to user expectations.

Objective Familial neuropsychological deficits are well established in schizophrenia but remain less well characterized in other psychotic disorders. This study from the Bipolar-Schizophrenia Network on Intermediate Phenotypes (B-SNIP) consortium 1) compares cognitive impairment in schizophrenia and bipolar disorder with psychosis, 2) tests a continuum model of cognitive dysfunction in psychotic disorders, 3) reports familiality of cognitive impairments across psychotic disorders, and 4) evaluates cognitive impairment among nonpsychotic relatives with and without cluster A personality traits. Method Participants included probands with schizophrenia (N=293), psychotic bipolar disorder (N=227), schizoaffective disorder (manic, N=110; depressed, N=55), their first-degree relatives (N=316, N=259, N=133, and N=64, respectively), and healthy comparison subjects (N=295). All participants completed the Brief Assessment of Cognition in Schizophrenia (BACS) neuropsychological battery. Results Cognitive impairments among psychotic probands, compared to healthy comparison subjects, were progressively greater from bipolar disorder (z=−0.77) to schizoaffective disorder (manic z=−1.08; depressed z=−1.25) to schizophrenia (z=−1.42). Profiles across subtests of the BACS were similar across disorders. Familiality of deficits was significant and comparable in schizophrenia and bipolar disorder. Of particular interest were similar levels of neuropsychological deficits in relatives with elevated cluster A personality traits across proband diagnoses. Nonpsychotic relatives of schizophrenia probands without these personality traits exhibited significant cognitive impairments, while relatives of bipolar probands did not. Conclusions Robust cognitive deficits are present and familial in schizophrenia and psychotic bipolar disorder. Severity of cognitive impairments across psychotic disorders was consistent with a continuum model, in which more prominent affective features and less

Multiple Determinations of Sperm DNA Fragmentation Show That Varicocelectomy Is Not Indicated for Infertile Patients with Subclinical Varicocele

2014-01-01

Full Text Available Varicocele is one of the most common causes of low semen quality, which is reflected in high percentages of sperm cells with fragmented DNA. While varicocelectomy is usually performed to ameliorate a patient’s fertility, its impact on sperm DNA integrity in the case of subclinical varicocele is poorly documented. In this study, multiple DNA fragmentation analyses (TUNEL, SCD, and SCSA were performed on semen samples from sixty infertile patients with varicocele (15 clinical varicoceles, 19 clinical varicoceles after surgical treatment, 16 subclinical varicoceles, and 10 subclinical varicoceles after surgical treatment. TUNEL, SCD, and SCSA assays all showed substantial sperm DNA fragmentation levels that were comparable between subclinical and clinical varicocele patients. Importantly, varicocelectomy did improve sperm quality in patients with clinical varicocele; however, this was not the case in patients with subclinical varicocele. In summary, although infertile patients with clinical and subclinical varicocele have similar sperm DNA quality, varicocelectomy should only be advised for patients with clinical varicocele.

Velo-cardio-facial syndrome and psychotic disorders: Implications for psychiatric genetics

Psychiatric disorders have been reported in over 10% of patients with velo-cardio-facial syndrome (VCFS) in long-term follow-up. To further explore the behavioral and psychiatric findings associated with VCFS in adulthood, detailed clinical histories of two patients - one with VCFS who developed a psychotic illness, and one with schizophrenia who was found to have dysmorphological features associated with VCFS - are described in the current report. The observed overlap of physical and psychiatric symptoms in these two patients suggests that VCFS and psychotic disorders may share a pathogenetic mechanism. This could be consistent with a contiguous gene model for VCFS and psychosis, suggesting chromosome 22q11 as a possible candidate region for genetic studies of schizophrenia. 26 refs., 2 tabs.

Psychotic-like experiences (PLEs) are considered predictive of mental health problems later in life. However, little has been known about the mental health status and psychopathological distress in adolescents with PLEs in the general population. To investigate the associations between PLEs and mental health status or psychopathologies in a community sample of adolescents in a school-based cross-sectional fashion, PLEs were studied using a self-rating questionnaire in 5073 Japanese junior-high school students aged 12-15 years. Mental health status was evaluated using the 12-item General Health Questionnaire (GHQ-12). Psychopathologies, lifestyle, victimization, and interpersonal and help-seeking attitudes were also studied using a self-rating questionnaire. Fifteen percent of the students reported definitely having experienced at least one PLE. A dose-response relationship between the severity of PLEs and the prevalence of poor mental health status was observed. PLEs were also significantly associated with psychopathologies (strong anxiety in the classroom: OR = 1.4, 95% CI 1.2-1.6; suicidal ideation: OR = 2.1, 95% CI 1.8-2.4; self-harm behaviors: OR = 1.4, 95% CI 1.0-1.9; difficulty falling asleep due to hypersensitivity to environmental noise: OR = 1.7, 95% CI 1.4-2.0; difficulty concentrating due to hypersensitivity to environmental noise: OR = 1.5, 95% CI 1.3-1.8; physically assaulting others: OR = 1.3, 95% CI 1.0-1.5; bullying others, OR = 1.3, 95% CI 1.1-1.5; irritability when exchanging e-mails: OR = 1.3, 95% CI 1.0-1.6). Adolescents with PLEs in the community suffer from a wide range of psychopathological problems during crucial developmental periods [corrected

2018-02-01

Neurofibromatosis type 2 (NF2) is mainly associated with central nervous system (CNS) tumors. Peripheral nerve involvement is described in symptomatic patients, but evidence of subclinical peripheral nerve involvement is scarce. We conducted a cross-sectional pilot study in 2 asymptomatic and 3 minimally symptomatic patients with NF2 to detect subclinical peripheral nerve involvement. Patients underwent clinical examination, nerve conduction studies (NCS), and high-resolution ultrasonography (HRUS). A total of 30 schwannomas were found, divided over 20 nerve segments (33.9% of all investigated nerve segments). All patients had at least 1 schwannoma. Schwannomas were identified with HRUS in 37% of clinically unaffected nerve segments and 50% of nerve segments with normal NCS findings. HRUS shows frequent subclinical peripheral nerve involvement in NF2. Clinicians should consider peripheral nerve involvement as a cause of weakness and sensory loss in the extremities in patients with this disease.

Context: Studies of long-term outcomes of subclinical hypothyroidism have assessed only baseline thyroid function, despite natural transitions to euthyroidism and overt hypothyroidism over time. Objective: We provide estimates of persistence, resolution, and progression of subclinical hypothyroidism over 4 yr, stratified by baseline TSH, anti-thyroid peroxidase antibody (TPOAb) status, age, and sex. Design, Setting, and Participants: Participants were 3996 U.S. individuals at least 65 yr old enrolled in the Cardiovascular Health Study. Subclinical hypothyroidism was detected at baseline in 459 individuals not taking thyroid medication. Main Outcome Measure: Thyroid function was evaluated at 2 and 4 yr and initiation of thyroid medication annually. Results were stratified by baseline TSH, TPOAb status, age, and sex. Results: Persistence of subclinical hypothyroidism was 56% at 2 and 4 yr. At 2 yr, resolution was more common with a TSH of 4.5–6.9 mU/liter (46 vs. 10% with TSH 7–9.9 mU/liter and 7% with TSH ≥10 mU/liter; P hypothyroidism (P hypothyroidism were common between 2 and 4 yr. Age and sex did not affect transitions. Conclusions: Subclinical hypothyroidism persists for 4 yr in just over half of older individuals, with high rates of reversion to euthyroidism in individuals with lower TSH concentrations and TPOAb negativity. Future studies should examine the impact of transitions in thyroid status on clinical outcomes. PMID:22438233

Major depressive disorder with psychotic features may lead to misdiagnosis of dementia: a case report and review of the literature.

Major depressive disorder (MDD) with psychotic features is relatively frequent in patients with greater depressive symptom severity and is associated with a poorer course of illness and greater functional impairment than MDD without psychotic features. Multiple studies have found that patients with psychotic mood disorders demonstrate significantly poorer cognitive performance in a variety of areas than those with nonpsychotic mood disorders. The Mini Mental State Examination (MMSE) and the Dementia Rating Scale, Second Edition (DRS-2) are widely used to measure cognitive functions in research on MDD with psychotic features. Established total raw score cut-offs of 24 on the MMSE and 137 on the DRS-2 in published manuals suggest possible global cognitive impairment and dementia, respectively. Limited research is available on these suggested cut-offs for patients with MDD with psychotic features. We document the therapeutic benefit of electroconvulsive therapy (ECT), which is usually associated with short-term cognitive impairment, in a 68-year-old woman with psychotic depression whose MMSE and DRS-2 scores initially suggested possible global cognitive impairment and dementia. Over the course of four ECT treatments, the patient's MMSE scores progressively increased. After the second ECT treatment, the patient no longer met criteria for global cognitive impairment. With each treatment, depression severity, measured by the 24-item Hamilton Rating Scale for Depression, improved sequentially. Thus, the suggested cut-off scores for the MMSE and the DRS-2 in patients with MDD with psychotic features may in some cases produce false-positive indications of dementia.

Evidence suggests that migrant groups have an increased risk of psychotic disorders and that the level of risk varies by country of origin and host country. Canadian evidence is lacking on the incidence of psychotic disorders among migrants. We sought to examine the incidence of schizophrenia and schizoaffective disorders in first-generation immigrants and refugees in the province of Ontario, relative to the general population. We constructed a retrospective cohort that included people aged 14-40 years residing in Ontario as of Apr. 1, 1999. Population-based administrative data from physician billings and hospital admissions were linked to data from Citizenship and Immigration Canada. We used Poisson regression models to calculate age- and sex-adjusted incidence rate ratios (IRRs) and 95% confidence intervals (CIs) for immigrant and refugee groups over a 10-year period. In our cohort (n = 4,284,694), we found higher rates of psychotic disorders among immigrants from the Caribbean and Bermuda (IRR 1.60, 95% CI 1.29-1.98). Lower rates were found among immigrants from northern Europe (IRR 0.50, 95% CI 0.28-0.91), southern Europe (IRR 0.60, 95% CI 0.41-0.90) and East Asia (IRR 0.56, 95% CI 0.41-0.78). Refugee status was an independent predictor of risk among all migrants (IRR 1.27, 95% CI 1.04-1.56), and higher rates were found specifically for refugees from East Africa (IRR 1.95, 95% CI 1.44-2.65) and South Asia (IRR 1.51, 95% CI 1.08-2.12). The differential pattern of risk across ethnic subgroups in Ontario suggests that psychosocial and cultural factors associated with migration may contribute to the risk of psychotic disorders. Some groups may be more at risk, whereas others are protected. © 2015 Canadian Medical Association or its licensors.

Significance of radionucleid examination of joints in diagnosis of subclinical arthritis background

International Nuclear Information System (INIS)

Andersone, D.; Bulina, I.

2005-01-01

Background. A large group of inflammation arthritis is represented by seronegative spondyloarthropathies (SpA), including several nosologies: psoriatic arthritis Bechterev's disease, Reiter's disease, etc. One of the most common SpA forms is Reactive arthritis (ReA). Inflammation process in joints is the most characteristic symptom, which determines severeness, course and prognosis of the disease. One of the most sensitive methods of examination of joints is radionucleid (RN) examination. Increased RNV accumulation in the joints is not a specific feature .for a concrete disease, and growth of its accumulation corresponds to the exudative component of inflammation process which reveals the early stage of joint inflammation (subclinical arthritis). Objectives: To find out how often subclinical inflammation processes (subclinical sinovitis) are observed in patients with minimal systemic activity of ReA. To detect in which joints subclinical sinovitis localizes most commonly. To evaluate significance of radionucleid examinations in diagnosis of subclinical arthritis. Material and methods. RN examination of joints was performed in 41 patient with ReA in I stage of activity and in 35 patients with ReA in II stage of activity, when the causative agent of infection - Chlamydia trachomatis - is localized in the urogenital tract. ReA was diagnosed according to diagnostic criteria of French Rheumatologists Association. For clinical description of joints index was used, characterized by pain intensity during joint palpation, and expressed by gradation degree from 0-3. In 76 patients with ReA I activity degree (ReA I) and ReA II activity degree (ReA II) radionucleid examination was done with marked 99 Tc and analysis of the obtained joint scintigrams for SI area. In the control group, 90 joint scintigrams were analyzed for patients with degenerative joint diseases without palpation pain in the examined joints, determining Tc index (Tc ind) in separate joints and summary Tc ind

MicroRNAs are short, non-coding molecules that regulate gene expression. Here, we investigate the role of microRNAs in depression and electroconvulsive therapy (ECT). We performed three studies: a deep sequencing discovery-phase study of miRNA changes in whole blood following ECT (n = 16), followed by a validation study in a separate cohort of patients pre-/post-ECT (n = 37) and matched healthy controls (n = 34). Changes in an experimentally validated gene target (VEGFA) were then analysed in patients pre-/post-ECT (n = 97) and in matched healthy controls (n = 53). In the discovery-phase study, we found no statistically significant differences in miRNA expression from baseline to end of treatment in the group as a whole, but post hoc analysis indicated a difference in patients with psychotic depression (n = 3). In a follow-up validation study, patients with psychotic depression (n = 7) had elevated baseline levels of miR-126-3p (t = 3.015, P = 0.006) and miR-106a-5p (t = 2.598, P = 0.025) compared to healthy controls. Following ECT, these differences disappeared. Baseline VEGFA levels were significantly higher in depressed patients compared to healthy controls (F(1,144) = 27.688, P = <0.001). Following ECT, there was a significant change in VEGFA levels in the psychotic group only (t = 2.915, P = 0.010). Molecular differences (miRNA and VEGFA) may exist between psychotic and non-psychotic depression treated with ECT. © 2017 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

Epilepsy is the most common serious neurological condition and sudden unexpected death in epilepsy (SUDEP) is the most important direct epilepsy-related cause of death. Information concerning risk factors for SUDEP is conflicting, but high seizure frequency is a potential risk factor. Additionally, potential pathomechanisms for SUDEP are unknown, but it is very probable that cardiac arrhythmias during and between seizures or transmission of epileptic activity to the heart via the autonomic nervous system potentially play a role. In parallel, several studies have shown a link between hormones and epilepsy. However, exact knowledge regarding the association of thyroid hormones and epilepsy is lacking. As subclinical hyperthyroidism has been linked with increased risk of cardiovascular disease, we propose in this paper that SUDEP, at least in some cases, could be related with subclinical thyroid dysfunction.

For people with persisting psychotic disorders, personal recovery has become an important target of mental health services worldwide. Strongly influenced by mental health service consumer perspectives, personal recovery refers to being able to live a satisfying and contributing life irrespective of ongoing symptoms and disability. Contact with peers with shared lived experience is often cited as facilitative of recovery. We aimed to develop and pilot a novel recovery-based digitally supported intervention for people with a psychotic illness. We developed a website to be used on a tablet computer by mental health workers to structure therapeutic discussions about personal recovery. Central to the site was a series of video interviews of people with lived experience of psychosis discussing how they had navigated issues within their own recovery based on the Connectedness-Hope-Identity-Meaning-Empowerment model of recovery. We examined the feasibility and acceptability of an 8-session low intensity intervention using this site in 10 participants with persisting psychotic disorders and conducted a proof-of-concept analysis of outcomes. All 10 participants completed the full course of sessions, and it was possible to integrate use of the website into nearly all sessions. Participant feedback confirmed that use of the website was a feasible and acceptable way of working. All participants stated that they would recommend the intervention to others. Post-intervention, personal recovery measured by the Questionnaire for the Process of Recovery had improved by an average standardized effect of d  = 0.46, 95% CI [0.07, 0.84], and 8 of the 10 participants reported that their mental health had improved since taking part in the intervention. In-session use of digital resources featuring peer accounts of recovery is feasible and acceptable and shows promising outcomes. A randomized controlled trial is the next step in evaluating the efficacy of this low intensity intervention

Fahr's syndrome is a rare disorder characterized by abnormal deposits of calcium in areas of the brain that control movement, including the basal ganglia and the cerebral cortex associated with many neurological and psychiatric abnormalities such as a rigid hypokinetic syndrome, mood disorders and cognitive impairment. Fahr's syndrome is secondary to some disorders, such as hypoparathyroidism. We report the case of a 56 year-old man, with a history of cataract, who was admitted to our psychiatric hospital for the first time in his life because of psychotic symptoms associated with irritability and aggressiveness. Since the age of 38 the patient had become nervous, 10 years later he developed tonic-clonic seizures. Two months ago, he began expressing delusions of persecution against his wife and sons and making fugues. According to his family during this period, he was agitated, aggressive, and suffered from insomnia and anorexia. The general and psychiatric examination showed an upright and bronzed patient with neglected hygiene. He was indifferent to his environment and expressed poor mimics and gestures. He was anxious, suspicious and not very talkative. He was conscious but his attention was slightly decreased. Moreover, he was not aware of his problems. The neurological examination showed extrapyramidal syndrome with postural tremor and cerebellar ataxia. A cranial computed tomography brain scan found bilateral, symmetric basal ganglia calcifications, in favour of Fahr's syndrome. Phosphocalcic investigations revealed low concentration of serum calcium at 1.01mmol/L (normal 2.15 to 2.57mmol/L) and hyperphosphoremia at 2.69mmol/L (normal 0.81 to 1.55mmol/L). He also had low concentrations of 25-OH vitamin as well as decreased urinary levels of phosphate and calcium. The blood level of parathyroid hormone was 0ng/L. The diagnosis of Fahr's syndrome, revealing a hypoparathyroidism was posed. He was supplemented with calcium and alpha cholecalciferol and treated

GABA system genes have been implicated in neurotrophy and neurogenesis, which play pivotal roles in an individual's variation in vulnerability to amphetamine addiction or amphetamine-induced psychosis (AIP). We hypothesized that common genetic variants in the GABA system genes may be associated with amphetamine-induced psychotic disorder. In our study, thirty-six single nucleotide polymorphisms (SNPs) within the GABA system genes were genotyped in 400 amphetamine-induced psychotic disorder patients and 400 amphetamine use disorders patients (AUP) (not including those categorized as psychosis) in the Han Chinese population. In this study, 51.88% of the Han Chinese amphetamine-type substance use disorder patients met the criteria of amphetamine-induced psychotic disorder, and 79.5% amphetamine-induced psychotic disorder patients had auditory hallucinations, while 46.5% had delusions of reference. The allele frequency of rs1129647 showed nominal association with AIP in the Han Chinese population (P=0.03). Compared with AUP group patients, T allele frequency of AIP group patients was significantly increased. The adjustment for age and gender factors in the AIP and AUP patients was executed using unconditional logistic regression under five inheritance models. The genotype frequency of rs1129647 showed nominal association with AIP in the log-additive model (P=0.04). The genotype frequency of rs2290733 showed nominal association with AIP in the recessive model (P=0.04). Compared with female AIP patients, male patients were more likely to have the CC genotype of rs17545383 (P=0.04). Moreover, we determined that more male patients carried the T allele of rs2290733 in the AIP group (P=0.004). Unfortunately, the significant differences did not survive Benjamini-Hochberg false discovery rate correction (adjusted P>0.05). No association between the SNPs of the GABA system genes and amphetamine-induced psychotic disorder risk was identified. No haplotype of the GABA system

The long-term outcome of patients diagnosed with drug-induced psychotic disorders in China is unknown. Assess the course of illness and severity of psychiatric symptoms in patients previously admitted to a psychiatric hospital for treatment of psychotic symptoms that were induced by the use of illicit drugs. Patients with psychotic symptoms at the time of their first psychiatric admission who had used illicit drugs in the month prior to admission were followed up 13 to 108 months after admission. Patients and coresident family members were interviewed about post-discharge drug use and psychotic symptoms. The 258 identified patients were primarily young, unemployed males whose most common drug of abuse was methamphetamines and who had been abusing drugs for an average of 7 years at the time of admission. Among these patients 189 (73%) were located and reinterviewed; 168 (89%) had restarted illicit drug use and 25 (13%) had required rehospitalization over the follow-up period. In 114 patients (60%) the psychotic symptoms resolved in less than 1 month after stopping the drugs, in 56 (30%) the symptoms persisted for 1 to 6 months, and in 19 (10%) the symptoms persisted for longer than 6 months (in 8 of these the diagnosis had changed to schizophrenia). Compared to the other two groups, patients whose symptoms persisted more than 6 months were more likely to have a family history of mental illness, an earlier age of onset and a longer duration of drug abuse prior to the index admission; they were also more likely to have been re-hospitalized during the follow-up period and to have psychotic symptoms at the time of follow-up. Most patients with substance-induced psychotic disorders in our sample had a good long-term prognosis but those who started illegal drug use early, used drugs for prolonged periods, or had a family history of psychiatric illnesses were more likely to develop a chronic psychosis. Further prospective studies are needed to determine the relationship of

Sarcopenia, the age-related decline in muscle mass, affects the muscle strength and muscle quality, and these changes decrease functional capacity. The prevalence of thyroid dysfunction increases with age, and changes in thyroid hormone level lead to neuromuscular deficits. We investigated the effects of subclinical hypothyroidism on the muscle mass, strength or quality in elderly people. One thousand one hundred eighteen subjects aged > or = 65 yr were randomly selected from a local population and classified into a euthyroid (280 men and 358 women), subclinically hypothyroid (61 men and 75 women), or overtly hypothyroid (7 men and 16 women) group. Although women with subclinical hypothyroidism had a higher prevalence of sarcopenia, defined according to the ratio of appendicular skeletal muscle mass to the square of height, muscle mass, strength or quality did not differ in relation to thyroid status in men or in women. Multivariate analysis including age, diabetes, hypertension, acute coronary event, alcohol, smoking, presence of pain, physical activity score, and lipid profile, showed that thyroid-stimulating hormone level was not associated with muscle mass, strength or quality. In conclusion, subclinical hypothyroidism has little influences on muscle mass, strength or quality, and may not be associated with sarcopenia.

Psychotic spectrum disorders present treatment challenges for patients, families, and clinicians. This article addresses the history of the dualism in the field between biological and psychological approaches to mental disorders, and surveys the contemporary literature about the etiology and treatment of psychotic spectrum disorders. An integrative approach to treatment derived from work at Austen Riggs with previously treatment refractory patients with psychotic spectrum disorders is described that combines individual psycho- dynamic psychotherapy, psychopharmacology, family systems approaches, and intensive psychosocial engagement. Helping patients develop their own authority to join the treatment, use relationships for learning, and understand the meaning of their symptoms is central to the treatment at Austen Riggs. An extended case vignette of a patient diagnosed with a schizoaffective disorder is presented illustrating this integrative psychodynamic treatment approach.

Subclinical Hypothyroidism in Children and Adolescents: a single-center retrospective study

Conclusion: The mild form of subclinical hypothyroidism was the most common typepf disease and, among patients managed conservatively, the majority presented normal thyroid function after one year of follow-up and none progressed to overt hypothyroidism. Our results reinforce the idea that, in most patients, subclinical hypothyroidism is a benign condition with a low risk of progression to overt thyroid dysfunction. However, further studies are needed to evaluate the potential long-term effects of the condition in untreated patients and to clarify the best clinical approach and follow-up strategy.

Method: Consecutive patients who were admitted (n = 51 with a confirmed diagnosis of major depression with psychotic features (delusions or hallucinations or both participated in this open-label, naturalistic study. All patients were treated with selective serotonin reuptake inhibitors (SSRIs and serotonin–norepinephrine reuptake inhibitors (SNRIs (citalopram or venlafaxine extended release [XR], and atypical antipsychotic agents were added, as tolerated, during the first week of initiating the citalopram or venlafaxine. There were patients (n = 16 who received risperidone, who received quetiapine (n = 20, and who received olanzapine (n = 15, as an adjunctive treatment to either citalopram or venlafaxine for at least 8 weeks. Outcome measures included the Clinical Global Impression-Severity subscale (CGI-S, as the primary outcome measure, as well as the Hamilton Rating Scale for Depression-21 item (HAM-D21 and the Brief Psychiatric Rating Scale (BPRS. Tolerance to treatments and weight changes were monitored over the period of the trial. Results: All patients completed the trial with no drop outs. At 8 weeks, there was a statistically significant (P 0.01 in the olanzapine group. Conclusion: Quetiapine, risperidone, and olanzapine, given as adjunctive treatment with SSRIS or SNRIs can significantly and equally improve depressive and psychotic symptoms, in the short-term treatment of major depression with psychotic features. The author recommends that large controlled trials be conducted to examine the differences in long-term efficacy and tolerance between the atypical antipsychotic agents, in the treatment of major depression with or without psychotic features.

Obesity and psychotic disorders: uncovering common mechanisms through metabolomics

Directory of Open Access Journals (Sweden)

Matej Orešič

2012-09-01

Full Text Available Primary obesity and psychotic disorders are similar with respect to the associated changes in energy balance and co-morbidities, including metabolic syndrome. Such similarities do not necessarily demonstrate causal links, but instead suggest that specific causes of and metabolic disturbances associated with obesity play a pathogenic role in the development of co-morbid disorders, potentially even before obesity develops. Metabolomics – the systematic study of metabolites, which are small molecules generated by the process of metabolism – has been important in elucidating the pathways underlying obesity-associated co-morbidities. This review covers how recent metabolomic studies have advanced biomarker discovery and the elucidation of mechanisms underlying obesity and its co-morbidities, with a specific focus on metabolic syndrome and psychotic disorders. The importance of identifying metabolic markers of disease-associated intermediate phenotypes – traits modulated but not encoded by the DNA sequence – is emphasized. Such markers would be applicable as diagnostic tools in a personalized healthcare setting and might also open up novel therapeutic avenues.

Background and objectives : Subclinical hypothyroidism is an asymptomatic condition with normal thyroxin and raised thyroid stimulating hormone (TSH) level. The objective of the study was to determine the prevalence of subclinical hypothyroidism in primary health care (PHC) settings in Riyadh and explore the relationship of TSH level with age, gender, family history, body mass index, and co-morbid conditions. Subjects and methods : A cross-sectional study of adult visitors to nine satellites PHC clinics in military housing in Riyadh was carried out. TSH concentration and free T4 levels were measured. Data were collected by nurses and physicians during routine clinical practice in primary care. Descriptive analysis was performed on all variables in study, and relationships were explored using chi-square, t -test, analysis of variance, and linear regression. Results : A total of 340 out of 394 participants in the study gave blood samples. Subclinical hyperthyroidism was identified in 2.1% ( p  = .001) and subclinical hypothyroidism in 10.3% ( p  = .001) of the PHC visitors. TSH levels were found to be significantly higher ( p  = .047) in elderly population of ≥60 years and those with family history of thyroid disease. Non-significant upward trends were noted in TSH levels with hyperlipidemia and increasing blood pressure. No overt hyperthyroidism or hypothyroidism was found in our study sample. Conclusion : Subclinical hypothyroidism has a prevalence of 10% of adults visiting PHC's. TSH levels are higher in the elderly, which warrants screening of those aged 60 years and above.

Childhood trauma is associated with higher risk for mental disorders, including psychosis. Heightened sensitivity to social stress may be a mechanism. This virtual reality study tested the effect of childhood trauma on level of paranoid ideations and distress in response to social stress, in interaction with psychosis liability and level of social stress exposure. Seventy-five individuals with higher psychosis liability (55 with recent onset psychotic disorder and 20 at ultra-high risk for psychosis) and 95 individuals with lower psychosis liability (42 siblings and 53 controls) were exposed to a virtual café in five experiments with 0-3 social stressors (crowded, other ethnicity and hostility). Paranoid ideation was measured after each experiment. Subjective distress was self-rated before and after experiments. Multilevel random regression analyses were used to test main effects of childhood trauma and interaction effects. Childhood trauma was more prevalent in individuals with higher psychosis liability, and was associated with higher level of (subclinical) psychotic and affective symptoms. Individuals with a history of childhood trauma responded with more subjective distress to virtual social stress exposures. The effects of childhood trauma on paranoia and subjective distress were significantly stronger when the number of virtual environmental stressors increased. Higher psychosis liability increased the effect of childhood trauma on peak subjective distress and stress reactivity during experiments. Childhood trauma is associated with heightened social stress sensitivity and may contribute to psychotic and affective dysregulation later in life, through a sensitized paranoid and stress response to social stressors.

Hyperthyroidism is associated with various movement disorders, such as chorea and tremors. We report on a young Chinese woman with an unusual presentation of myoclonus, involving both platysmal muscles, in association with subclinical hyperthyroidism. The myoclonus was preceded by symptoms of hyperthyroidism, namely weight loss, menstrual disturbances, and heat intolerance. The movements abated with clonazepam and hyperthyroidism was treated with carbimazole. The myoclonus recurred briefly when she stopped taking clonazepam, but she has since remained well and euthyroid. Copyright 2005 Movement Disorder Society

The aim of this study was to determine signs of subclinical endometritis found by ultrasound that are associated with reduced fertility in dairy cows. The maximum diameter of the uterine lumen was determined by ultrasound in 324 cows without clinical signs of endometritis after evaluation of the genital tract 21 to 27 days postpartum. Cows were classified into healthy or with subclinical endometritis by three threshold values for the maximum uterine lumen diameter of 0.2 cm, 0.5 cm or 0.8 cm. Examinations by rectal palpation and ultrasound as well as classifications were repeated 14 days later. In addition, ovaries were scanned by ultrasound to determine the stage of the estrous cycle. In a subgroup of 103 cows the echotexture of the uterus and its contents was evaluated. In these cows the diagnosis of subclinical endometritis was performed by a scoring system. The diameter of the uterine lumen was significantly affected by stage of the estrous cycle at the time of examination. However, no effects were found for the stage of the cycle at the time of examination on subsequent reproductive performance. A uterine lumen with a maximum diameter of more than 0.2 cm showed a significant negative association with conception rate and proportion of cows pregnant. Classification based on higher threshold values did not reveal an association with reproductive performance. Echogenic content in the uterus also decreased reproductive performance. A classification based on the echotexture of the uterus and its contents revealed significant differences between healthy cows and cows with subclinical endometritis regarding the proportion of cows inseminated and pregnant. The results of this study showed that the diagnostic of bovine endometritis should be broadend by ultrasonography. The definition of subclinical endometritis diagnosed by means of ultrasonography has to be evaluated in further studies.

Full Text Available BACKGROUND Metabolic Syndrome (MetS is generally characterised as a clustering of the abnormal levels of blood lipids (low HDL and high triglycerides, impaired fasting glucose, elevated blood pressure, and excess abdominal obesity. The objectives of the study areTo evaluate presence of Subclinical Hypothyroidism in the study population of the patients with metabolic syndrome. To find out relation between Subclinical Hypothyroidism and different parameters of metabolic syndrome. To evaluate whether patients of metabolic syndrome with raised hs-CRP have an increased risk of having hypothyroidism. MATERIALS AND METHODS A total of 50 adult patients who met with inclusion criteria were selected. Patients with metabolic syndrome (MetS who fulfilled the NCEP-ATP III criteria: 3 out of 5 criteria positive. Patients with liver disorders, renal disorders, congestive cardiac failure, pregnant women, patients on oral contraceptive pills, statins and other medications that alter thyroid functions (e.g. lithium, amiodarone or γ-interferon were excluded from the study. RESULTS A total of 50 patients of metabolic syndrome were enrolled. Out of which 36 were euthyroid, 3 were overt hypothyroid and 11 were subclinical hypothyroid. Out of 11 patients of subclinical hypothyroidism, 9 were female and 2 were male patients. Out of 28 females, 9 (32% were SCH while out of 22 males, 2 (9% were SCH. Out of 50 patients, 3 were overt hypothyroid. All 3 patients had BP >130/85, waist circumference was >88 cm and HDL of 130/85, HDL 150 mg/dL and fasting blood glucose of >100 mg/dL were more associated with male patients. CONCLUSION Subclinical Hypothyroidism was present in 22% of study population and more so in females having metabolic syndrome (32%. Hence, it will be worthwhile to screen female metabolic syndrome patients for thyroid function abnormality. Abnormal blood pressure, triglycerides and HDL cholesterol levels were more associated with subclinical hypothyroidism

To evaluate the frequency of subclinical lead toxicity. Cross-sectional study. Department of Pathology and Laboratory Medicine, The Aga Khan University Hospital, Karachi, from January 2011 to December 2014. Analysis of laboratory data for blood lead levels (BLL) was performed. Lead was tested by atomic absorption spectrometer. For all subjects, only initial test results were included while the results of repeated testing were excluded. Exemption was sought from institutional ethical review committee. BLL of 2-10 ug/dl and 10-70 ug/dl in children and adults, respectively were taken as subclinical lead toxicity. Amongst the total number of subjects tested (n=524), 26.5% (n=139) were children (lead level 16.9 ug/dl (36.1-4)] and lower level [4.2 ug/dl (6.8-2.6)] in children with lead levels while most had either subclinical (76%, n=106) or toxic lead levels (8%, n=11). In adults, (55%, n=212) subjects had desired lead levels, and 40% (n=154) and 4.99% (n=19) had subclinical and toxic lead levels. Presence of subclinical lead poisoning even after phasing out of lead petroleum in Pakistanis is alarming, especially in children. A national population-based study to determine the lead status and targeted intervention to identify potential sources is need of the time.

The dairy industry has undergone substantial structural changes as intensive farming has developed during recent decades. Mastitis continues to be the most common production disease of dairy cows. Nationwide surveys of mastitis prevalence are useful in monitoring udder health of dairy herds and to study the impact of structural changes on the dairy industry. This survey on bovine subclinical mastitis was the first based on cow composite milk somatic cell count (SCC) data from the Finnish national health monitoring and milk recording database. A cow with composite milk SCC ≥200,000 cells/ml in at least one of the four test milkings during the year was considered to have subclinical mastitis and a cow with composite milk SCC ≥200,000 cells/ml in three or in all four test milkings during the year to have chronic subclinical mastitis. The aim of the study was to determine the prevalence of subclinical mastitis and chronic subclinical mastitis in Finland in 1991, 2001 and 2010 and to investigate cow and herd factors associated with elevated SCC. Prevalence of subclinical mastitis in Finland decreased over recent decades from 22.3% (1991) and 20.1% (2001) to 19.0% (2010). Prevalence of chronic subclinical mastitis was 20.4% in 1991, 15.5% in 2001 and 16.1% in 2010. The most significant cow and herd factors associated with subclinical mastitis or high milk SCC were increasing parity, Holstein breed, free-stalls with an automatic milking system and organic production. Milk SCC were highest from July to September. Main factors associated with chronic mastitis were increasing parity and Holstein breed. Prevalence of subclinical mastitis in Finland decreased over recent decades, the greatest change taking place during the first decade of the study. Prevalence of chronic subclinical mastitis significantly decreased from 1991. The most significant factors associated with both types of mastitis were increasing parity and Holstein breed, and for subclinical mastitis also

Recent life events are associated with transition to and outcome in psychosis. Childhood trauma and personality characteristics play a role in proneness to adult life events. However, little is known about the relative contribution and interrelatedness of these characteristics in psychotic disorders. Therefore, we investigated whether Five-Factor Model (FFM) personality traits and childhood trauma (abuse and neglect) predict adult life events, and whether the effect of childhood trauma on life events is mediated by personality traits. One hundred and sixty-three patients with psychotic disorders were assessed at baseline on history of childhood maltreatment and FFM personality traits, and on recent life events at 3-year follow-up. Childhood abuse is associated with negative life events, and part of the effect of childhood abuse on negative life events is mediated by openness to experience. Openness to experience and extraversion are associated with more positive and negative life events. Childhood neglect and lower extraversion are related to experiencing less positive events. The association between childhood trauma and recent life events is partly mediated by personality. Future research could focus on mechanisms leading to positive life events, as positive life events may buffer against development of mental health problems.

Autism and schizophrenia spectrum research is typically based on coarse diagnostic classification, which overlooks individual variation within clinical groups. This method limits the identification of underlying cognitive, genetic and neural correlates of specific symptom dimensions. This study, therefore, aimed to identify homogenous subclinical subgroups of specific autistic and schizotypal traits dimensions, that may be utilised to establish more effective diagnostic and treatment practices. Latent profile analysis of subscale scores derived from an autism-schizotypy questionnaire, completed by 1678 subclinical adults aged 18-40 years (1250 females), identified a local optimum of eight population clusters: High, Moderate and Low Psychosocial Difficulties; High, Moderate and Low Autism-Schizotypy; High Psychosis-Proneness; and Moderate Schizotypy. These subgroups represent the convergent and discriminant dimensions of autism and schizotypy in the subclinical population, and highlight the importance of examining subgroups of specific symptom characteristics across these spectra in order to identify the underlying genetic and neural correlates that can be utilised to advance diagnostic and treatment practices.

This study investigated the presence of sub-clinical cognitive dysfunction in patients with clinically isolated syndrome (CIS) and the abnormalities of cognitive event-related potentials (ERPs). Subclinical cognitive dysfunction was assessed in 20 patients with CIS and in 20 healthy controls. Patients had impairments in verbal learning and long-term memory, evaluating attention, executive function and visuospatial skills, in decreasing order of frequency. SDLT and SIT were the most, and COWAT and BNT were the least affected tests. The N200 and P200 latencies were prolonged, and N100, N200 and P200 amplitudes were reduced in the patients relative to the controls, from the Fz, Cz and Pz electrode positions (p<0.05). Detailed cognitive testing is valuable in determining subclinical cognitive dysfunction in CIS patients. ERP abnormalities as well as abnormalities in detailed cognitivetesting in patients with CIS are helpful in the diagnosis of sub-clinical cognitive dysfunction.

2007-11-01

Chronic subclinical mastitis is usually not treated during the lactation. However, some veterinarians regard treatment of some types of subclinical mastitis to be effective. The goal of this research was to develop a stochastic Monte Carlo simulation model to support decisions around treatment of chronic subclinical mastitis caused by Streptococcus uberis. Factors in the model included the probability of cure after treatment, probability of the cow becoming clinically diseased, transmission of infection to other cows, and physiological effects of the infection. Using basic input parameters for Dutch circumstances, the average economic costs per cow of an untreated chronic subclinical mastitis case caused by Str. uberis in a single quarter from day of diagnosis onwards was euro109. With treatment, the average costs were higher (euro120). Thus, for the average cow, treatment was not efficient economically. However, the risk of high costs was much higher when cows with chronic subclinical mastitis were not treated. A sensitivity analysis showed that profitability of treatment of chronic subclinical Str. uberis mastitis depended on farm-specific factors (such as economic value of discarded milk) and cow-specific factors (such as day of diagnosis, duration of infection, amount of transmission to other cows and cure rate). Therefore, herd level protocols are not sufficient and decision support should be cow specific. Given the importance of cow-specific factors, information from the current model could be applied to automatic decision support systems.

Full Text Available Background/Aim. Consequences of individual adverse childhood experiences for adult mental health have been precisely studied during past decades. The focus of past research was mainly on childhood maltreatment and neglect. The aim of this paper was to determine association between multiple adverse childhood experiences and psychiatric disorders, as well as their correlation to the degree and type of aggressiveness in adult psychiatric patients. Methods. One hundred and thirteen psychiatric outpatients were divided into three diagnostic groups: psychotics, non-psychotics and alcoholics and compared with fourty healthy individuals. Adverse childhood experiences data were gathered retrospectively, using the Adverse childhood experiences questionnaire and explanatory interview. Aggressiveness was assessed using Buss-Perry Aggression Questionnaire. The Student's t test, ANOVA and correlational analysis were used for evaluation of statistical significance of differences among the groups. A value p < 0.05 was considered statistically significant. Results. Our results showed that the mean number of adverse childhood experiences in each group of psychiatric patients, as well as in the whole group of patients, was statistically significantly higher than in the group of healthy individuals (p < 0.001; there was a statistically significant difference in score of physical aggressiveness between the patients exposed to adverse childhood experiences and those who were not exposed to them (p < 0.05; scores of physical aggressiveness were in positive correlation with the number of adverse childhood experiences (p < 0.05. The highest mean score of adverse childhood experiences was evidenced in the group of patients with psychotic disorders. Conclusion. Multiple adverse childhood experiences are significantly associated with psychotic disorders, nonpsychotic disorders and alcohol dependence in adulthood and their presence is important morbidity risk factor for

The excess mortality associated with depressive disorders has been most often attributed to risks for suicide but diverse findings indicate that depressive disorders also increase risks for cardiovascular (CV) mortality. Among the possible mediators is the hypothalamic-pituitary-adrenal (HPA)-axis hyperactivity that characterizes many cases of relatively severe depressive disorder and severity is characteristic of psychotic depressive disorder. The following describes a 17-year mortality follow-up of 54 patients with Research Diagnostic Criteria (RDC) psychotic major depression or schizoaffective, mainly affective, depression. All had baseline assessments that included a 1mg dexamethasone suppression test with post-dexamethasone samples at 8 a.m., 4 p.m. and 11 p.m. Regression analyses showed that both greater age and higher maximum post-dexamethasone cortisol concentrations predicted deaths due to CV causes (t=4.01, pdepressive disorder to CV mortality.

Full Text Available The human brain develops asymmetrically, such that certain cognitive processes arise predominantly from the left or right side. It has been proposed that variations in this laterality contribute to certain forms of mental illness, such as schizophrenia. A convenient measure of brain laterality is hand dominance, and prior work has found that patients with schizophrenia are more likely to be left-handed than the general population. This finding is not consistent, however, and fewer studies have directly compared handedness between psychiatric diagnoses. We assessed hand dominance in 107 patients presenting to an outpatient psychiatric clinic with diagnoses of a mood or psychotic disorder. The prevalence of left-handedness was 11% for mood disorders, which is similar to the rate in the general population. It was 40% in those with psychotic disorders (adjusted odds ratio = 7.9, p < .001. The prevalence of left-handedness was much higher in psychotic disorders compared with mood disorders in this community mental health sample.

Psychosocial rehabilitation and in particular group dances allow the recovery of lost or compromised ability of patients with mental illness, and they facilitate their reintegration into the social context. The dance group has enabled users of the Day Centre of the Unit of Mental Health Torre del Greco ASL NA 3 south to achieve the objectives of rehabilitation such as: taking care of themselves, of their bodies and their interests, improving self-esteem , the management of pathological emotions, socialization and integration, overcoming the psychotic closing and relational isolation. In particular, patients with schizophrenia, psychotic and mood disorders had a concrete benefit from such rehabilitation activities, facilitating interpersonal relationships, therapy compliance and significantly improved mood, quality of life, providing them with the rhythm and the security in their relationship with each other. The dance group and for some individuals, also psychotherapy and drug therapy, have facilitated social inclusion, improved the quality of life and cured their diseases. The work is carrying out in a group with patients, practitioners, family members, volunteers, social community workers, following the operating departmental protocols. Using the chorus group "Sing that you go" as an operational tool for psychosocial rehabilitation and therapeutic element we promote the psychological well-being and the enhancement of mood.

The recent investigations point out the significant role of oxidative stress in the development of thyroid gland disease. The present study was designed to investigate the variation of oxidative stae in women with non-autoimmunological subclinical hyperthyroidism. The study was conducted on 20 females with non-autoimmunological subclinical hyperthyroidism and 15 healthy women. Manganase-containing superoxide dismutase (Mn-SOD) and extracellular superoxide dismutase (EC-SOD) plasma activity, and malondialdehyde (MDA) plasma concentration were measured. EC-SOD plasma activity was significantly higher in women with subclinical hyperthyroidism when compared with the control group (13.3 +/- 2.1 vs. 10.9 +/- 1.4 NU/ml; p < 0.05), unlike Mn-SOD (4.2 +/- 0.5 vs. 4.0 +/- 1.0 NU/ml). MDA plasma concentration increased significantly in women with subclinical hyperthyroidism (3.5 +/- 1.2 vs. 2.0 +/- 0.6 micromol/l; p < 0.05). The increased EC-SOD plasma activity may reflect disturbances of oxidative state in subclinical hyperthyroidism. Parallel increase of MDA plasma concentration may indicate enhancement of lipid peroxidationin in patients with subclinical hyperthyroidism.

To evaluate the association between subclinical thyroid dysfunction and psychiatric disorders using baseline data from the Brazilian Longitudinal Study of Adult Health (ELSA-Brasil). Cross-sectional study. The study included 12 437 participants from the ELSA-Brasil with normal thyroid function (92·8%), 193 (1·4%) with subclinical hyperthyroidism and 784 (5·8%) with subclinical hypothyroidism, totalling 13 414 participants (50·6% of women). The mental health diagnoses of participants were assessed by trained raters using the Clinical Interview Schedule - Revised (CIS-R) and grouped according to the International Classification of Diseases 10 (ICD-10). Thyroid dysfunction was assessed using TSH and FT4 as well as routine use of thyroid hormones or antithyroid medications. Logistic models were presented using psychiatric disorders as the dependent variable and subclinical thyroid disorders as the independent variable. All logistic models were corrected for multiple comparisons using Bonferroni correction. After multivariate adjustment for possible confounders, we found a direct association between subclinical hyperthyroidism and panic disorder odds ratio [OR], 2·55; 95% confidence Interval (95% CI), 1·09-5·94; and an inverse association between subclinical hypothyroidism and generalized anxiety disorder (OR, 0·75; 95% CI, 0·59-0·96). However, both lost significance after correction for multiple comparisons. Subclinical hyperthyroidism was positively associated with panic disorder and negatively associated with anxiety disorder, although not significant after adjustment for multiple comparisons. © 2015 John Wiley & Sons Ltd.

The aim of this study was to model estimates related to (a) the incidence of psychotic disorders and (b) the mortality associated with these disorders based on a large, population-based prevalence study. Data were drawn from the second national survey of adults with psychotic disorders conducted in seven Australian catchment areas during March to December 2010. To generate incidence rate estimates, we identified recent onset cases recruited as part of the prevalence study and then imputed population-based incidence rates using a set of conservative assumptions. Similarly, for mortality rates, we identified individuals who had died after being identified as 'screen-positive' for psychosis, but prior to full clinical assessment. Using a set of conservative assumptions, we then used these estimates to infer population-based mortality rates. Based on our models, we estimated that the incidence rate for psychotic disorders was 28 cases per 100,000 population. The rate estimates were significantly higher in males than females, with an overall male:female ratio of 1.57:1. Incidence rate estimates peaked in the youngest age group (18-24 years). The adjusted mortality rate estimated during the whole period of observation was 12.5 per 1000 persons, with a standardised mortality ratio of 5.5. Using treated prevalence data and observed deaths with appropriate algorithms, we were able to impute incidence and mortality rates for psychotic disorders consistent with the published literature. While the second national survey of psychotic disorders was not designed to identify mortality, our estimates provide a stark reminder of the increased mortality associated with these disorders.

Context There are contradictory results on the effect of hyperthyroidism on hemostasis. Inadequate population-based studies limited their clinical implications, mainly on the risk of venous thromboembolism (VTE). The present review focuses on hemostatic changes in overt and subclinical hyperthyroidism. Methods A systematic literature search was conducted employing MEDLINE database. The following words were used for the search: Hyperthyroidism; thyrotoxicosis; Graves disease; goiter, nodular; hemostasis; blood coagulation factors; blood coagulation disorders; venous thromboembolism; bleeding; fibrinolysis. The articles that were related to hyperthyroidism and hemostasis are used in this manuscript. Results Hyperthyroidism, either overt or subclinical, renders a hypercoagulable state, although there are several studies with contradictory findings in the literature. Hypercoagulability may be caused by an increase in the level of various coagulation factors such as factor (F) VIII, FX, FIX, von Willebrand F (vWF), and fibrinogen, while hypofibrinolysis by changes in coagulation parameters such as a decrease in plasmin and plasmin activator or an increase in α2-antiplasmin, plasminogen activator inhibitor-1 and thrombin activatable fibrinolysis inhibitor Conclusions Although many reports are in favor of a hypercoagulable state in overt hyperthyroidism but this finding at the biochemical level and its clinical implication, on the occurrence of VTE, has yet to be confirmed.

Full Text Available Aim: To evaluate the effect of hypothyroidism (both overt and subclinical on cognitive function using latencies of P300 auditory evoked potentials (AEPs. P300 latency suggests that shorter latency times are related to better cognitive performance. P300 latencies were also done after thyroxine replacement to see the effect of treatment on cognitive function. Materials and Methods: Biochemically proven new onset cases with hypothyroidism (overt and subclinical were enrolled into the study, AEPs of these two groups when compared with matched controls. After detailed history and physical examination, P300 potentials were recorded at two points Cz and Pz (Cz: On the midline of the head at the vertex, Pz: On the midline of the head between the vertex and occipital protuberance using a Nicolet Viking Select neuro diagnostic system version 10.0. The study was done in electrophysiology lab in Osmania Medical College. Results: A patient characteristics of both cases and controls were comparable. The cases consisted of two groups, overt hypothyroid cases 24, mean thyroid stimulating hormone (TSH values in them was 94, subclinical cases 21 in whom mean TSH value was 12.3. Mean P300 latencies of all cases at Cz was 342.42 ± 29.5 ms, and at Pz was 345.4 ± 30 ms. Mean P300 latencies of controls at Cz was 296.4 ± 34 ms and at Pz was 297.9 ± 33 ms (difference in P < 0.001. Mean P300 values in overt cases were 362.6 ± 32.9 ms at Cz, and at Pz it was 362.5 ± 33.9 ms. Mean P300 values in subclinical cases were 319.3 ± 30.9 ms at Cz, and at Pz it was 316.4 ± 27.9 ms. P300 values in overt cases were highly significant as compared to controls, and P300 values in the subclinical cases versus controls were also significant (P < 0.001. Conclusion: P300 latency prolongation in both clinical and subclinical hypothyroid cases shows that cognitive function is affected adversely in hypothyroidism including the subclinical hypothyroid cases.
