Bilateral non-contiguous atypical papillary glioneuronal tumor:case report

Papillary glioneuronal tumor (PGNT) was first described as a distinct clinic-pathological entity by Komori et al. in 1998. Since then it has been included as a mixed neuronal-glial tumor in the revised WHO (2007) classification of central nervous system tumors. On brain imaging, it appears as a demarcated, solid to cystic, contrast-enhancing mass usually located in the temporal lobe. Histologically, it is considered a biphasic tumor characterized by small cuboidal GFAP-positive astrocytes around hyalinised blood vessels and synaptophysin-positive interpapillary collections of neurocytes, large neurons and intermediate-sized "ganglioid cells". Although they are generally regarded as benign WHO Grade I tumors, recent reports have described more pathologically aggressive features. To date, these reports have all been single lesions.

The making of a void sovereignty: political implications of the military checkpoints in the West Bank

Research on the Israeli checkpoints in the West Bank has emphasized not only that these checkpoints have dire implications for the Palestinians living there, at the personal, familial, and communal levels, and devastating eff ects on the Palestinian economy, but also that they have far-reaching consequences for the ability of the Palestinians to establish an independent political entity. At the same time, analysis of the Israeli forms of domination over the Palestinians has also stressed the role of a Palestinian governing authority in sustaining the Israeli rule, since the former relieves the latter of its responsibility to care for the occupied Palestinian population. This paper aims to address this apparent contradiction claiming that a comprehensive analysis of Israeli forms of domination requires a spatial examination of the operation of sovereignty with an assessment of governmentalizing arrays. This combined analysis suggests that a Palestinian sovereignty, but one which is emptied of its actual ruling power, is construed at the checkpoints as an epiphenomenon of Israeli apparatuses of control. © 2013 Pion and its Licensors.

Demos and Denomination::flags, fealty, and the political ontology of protests in Northern Ireland

This paper will examine some of the ways in which processes of denomination
have shaped Northern Irish politics before and after the ‘Belfast’, or ‘Good Friday
Agreement’ of 1998. We concentrate on the formation of the ‘Unionist’ or ‘Loyalist
community’, principally because the flag protests of 2012-2013 have brought the
issue of this community identity to the fore again. The flag is part of a whole
machinery of what we, in this paper, will call ‘denomination’ in Northern Irish
politics and elsewhere. The religious overtones of the term are neither accidental
nor incidental. Acts of denomination posit (assertively, authoritatively) a
collective identity, conceived and constituted ontologically, as an existent entity,
and stake a claim to a whole territory.

Genetic basis of Congenital Erythrocytosis:mutation update and online databases

Congenital Erythrocytosis (CE), or congenital polycythemia, represents a rare and heterogeneous clinical entity. It is caused by deregulated red blood cell production where erythrocyte overproduction results in elevated hemoglobin and hematocrit levels. Primary congenital familial erythrocytosis is associated with low erythropoietin (Epo) levels and results from mutations in the Epo receptor gene (EPOR). Secondary congenital erythrocytosis arises from conditions causing tissue hypoxia and results in increased Epo production. These include hemoglobin variants with increased affinity for oxygen (HBB, HBA mutations), decreased production of 2,3-bisphosphoglycerate due to BPGM mutations, or mutations in the genes involved in the hypoxia sensing pathway (VHL, EPAS1 and EGLN1). Depending on the affected gene, CE can be inherited either in an autosomal dominant or recessive mode, with sporadic cases arising de novo. Despite recent important discoveries in the molecular pathogenesis of CE, the molecular causes remain to be identified in about 70% of the patients. With the objective of collecting all the published and unpublished cases of CE the COST action MPN&MPNr-Euronet developed a comprehensive internet-based database focusing on the registration of clinical history, hematological, biochemical and molecular data (http://www.erythrocytosis.org/). In addition, unreported mutations are also curated in the corresponding Leiden Open Variation Database (LOVD). This article is protected by copyright. All rights reserved.

Considering Just-World Thinking in Counter-Terrorism Cases: Miscarriages of Justice in Northern Ireland

Recent literature has drawn a parallel between the discriminatory application of counterterrorism legislation to the Irish population in the United Kingdom during the Northern Ireland conflict and the targeting of Muslims after September 2001. Less attention has been paid to lessons that can be drawn from judicial decision making in terrorism-related cases stemming from the Northern Ireland conflict. This Article examines Northern Ireland Court of Appeal (“NICA”) jurisprudence on miscarriages of justice in cases regarding counterterrorism offenses. In particular, the Article focuses on cases referred after the 1998 peace agreements in Northern Ireland from the Criminal Cases Review Commission (“CCRC”), a relatively new entity that investigates potential wrongful convictions in England, Wales, and Northern Ireland. Although the NICA’s human rights jurisprudence has developed significantly in recent years, the study of CCRC-referred cases finds that judges have retained confidence in the integrity of the conflict-era counterterrorism system even while acknowledging abuses and procedural irregularities that occurred. This study partially contradicts contentions that judicial deference to the executive recedes in a post-conflict or post-emergency period. Despite a high rate of quashed convictions, the NICA’s decisions suggest that it seeks to limit a large number of referrals and demonstrate a judicial predisposition to defend the justness of the past system’s laws and procedure. This perspective is consistent with what social psychologists have studied as “just-world thinking,” in which objective observers, although motivated by a concern with justice, believe—as a result of cognitive bias—that individuals “got what they deserved.” The Article considers other potential interpretations of the jurisprudence and contends that conservative decision making is particularly dangerous in the politicized realm of counterterrorism and in light of the criminalization of members of suspect communities.

''We are an island”: Geographical Imagery in Accounts of Citizenship, Civil Society, and National Identity in Scotland and in England

In this article we question recent psychological approaches that equate the constructs of citizenship and social identity and which overlook the capacity for units of governance to be represented in terms of place rather than in terms of people. Analysis of interviews conducted in England and Scotland explores how respondents invoked images of Britain as “an island” to avoid social identity constructions of nationality, citizenship, or civil society. Respondents in Scotland used island imagery to distinguish their political commitment to British citizenship from questions relating to their subjective identity. Respondents in England used island imagery to distinguish the United Kingdom as a distinctive political entity whilst avoiding allusions to a common or distinctive identity or character on the part of the citizenry. People who had moved from England to Scotland used island imagery to manage the delicate task of negotiating rights to social inclusion in Scottish civil society whilst displaying recognition of the indigenous population’s claims to distinctive national culture and identity.

A worldwide survey of chronic cough: A manifestation of enhanced somatosensory response:A manifestation of enhanced somatosensory response

Reports from individual centres suggest a preponderance of females with chronic cough. Females also have heightened cough reflex sensitivity. Here we have reviewed the age and sex of unselected referrals to 11 cough clinics. To investigate the cause of any observed sex dimorphism, functional magnetic resonance imaging of putative cough centres was analysed in normal volunteers. The demographic profile of consecutive patients presenting with chronic cough was evaluated. Cough challenge with capsaicin was undertaken in normal volunteers to construct a concentration-response curve. Subsequent functional magnetic resonance imaging during repeated inhalation of sub-tussive concentrations of capsaicin observed areas of activation within the brain and differences in the sexes identified. Of the 10 032 patients presenting with chronic cough, two-thirds (6591) were female (mean age 55 years). The patient profile was largely uniform across centres. The most common age for presentation was 60-69 years. The maximum tolerable dose of inhaled capsaicin was lower in females; however, a significantly greater activation of the somatosensory cortex was observed. Patients presenting with chronic cough from diverse racial and geographic backgrounds have a strikingly homogeneous demographic profile, suggesting a distinct clinical entity. The preponderance of females may be explained by sex-related differences in the central processing of cough sensation.

Intra-testicular varicocele presenting as acute scrotum

The term varicocele describes a dilated, tortuous and elongated pampiniform plexus of veins, which is well known in relation to the spermatic cord. Recently varicocele has also been observed inside the testis, and this new entity is known as intra-testicular varicocele. We present a case of intra-testicular varicocele presenting as acute scrotum and discuss the management issues.

Stereotactic Body Radiotherapy for Oligometastatic Disease

Stereotactic body radiotherapy (SBRT) is now an established therapy in stage I lung cancer with comparable local control rates to surgical resection. Owing to the conformity of treatment dose delivery and with appropriate fractionation considerations, minimal side-effects to surrounding normal tissues are observed in most patients. SBRT is now being used in the treatment of oligometastatic disease, alone or alongside systemic therapy. At present there is a paucity of evidence available showing a clinical benefit, but several international studies are being set-up or have started recruitment. This overview considers the clinical entity of an oligometastatic state, discusses the role of SBRT in the management of oligometastatic disease and discusses potential novel therapy combinations with SBRT.

The Ulster Covenant and the Pulse of Protestant Ulster

The signing of the Ulster Covenant on 28 September 1912 by almost 450,000 men and women was a powerful act of defiance on the part of Unionists in the context of what they perceived as the threat to their way of life represented by the Liberal Government's policy of Irish Home Rule. This article attempts to look beyond the well-studied leadership figures of Carson and Craig in order to fashion insights into the way Ulster Protestant society was mobilised around the Covenant and opposition to Home Rule. It draws attention to hitherto over-shadowed personalities who can be said to have exerted crucial local influence. It also contends that although pan-Protestant denominational unity provided the basis for the success of the Covenant, the Presbyterian community was particularly cohesive and purposeful in the campaign. The article further argues that the risk-taking defiance that came more easily to the Presbyterians, on account of a troubled history, largely evaporated in the new political circumstances of Northern Ireland when it became a separate devolved political entity within the UK from 1921.

Leukaemogenesis, gene interplay, and the role of the haemopoietic environment

Malignant initiation, leukaemic transformation, and disease progression in haematological malignancies involves a series of mutational events in genes involved in normal housekeeping functions of the cell. These acquired genetic changes can lead to either increased proliferation or a decreased rate of apoptosis, thus allowing expansion of the malignant clone. Although leukaemia can arise as a de novo disease, it has become increasingly clear that therapies, including the use of irradiation and/or chemotherapy, can give rise to malignancy. Therapy-associated myelodysplasia (t-MDS) and therapy-associated acute myeloid leukaemia (t-AML) account for 10-20% of new cases of these diseases. Although these secondary malignancies have been recognised as a clinical entity for nearly 30 years, molecular studies are now pinpointing various regions of the genome that are susceptible to DNA damage by these chemotherapeutic/radiotherapeutic strategies. The detection of new malignancies (both solid tumours and haematological tumours) following allogeneic bone marrow transplantation (BMT) is also providing us with some clues to the nature of leukaemogenesis, particularly with the observation that leukaemia can occur in donor cells postallogeneic BMT.

Utopia Incomplete: British New Towns and Craigavon

The New towns initiative in the UK and Northern Ireland, enshrined in the Act of 1946, was derived out of a stream of philosophical thought that was a reaction to modernity, paritcularly Victorian industrialisation. This was developed through the writings of Ruskin and Morris and crystalised by Ebenezer Howard in his book Garden Cities of Tomorrow, which culminated with the design of Letchworth by Parker and Unwin (completed 1914). Letchworth however, was a more than just a physical and spatial entity: it was actually a policyscape, a novel economic and social policy landscape that regulated development in a modern and scientific way.

These themes of the scientification of urban design, and the regulation of urban development through policy, run through the whole New Town movement, right up to the development of the eco-towns of today. New Towns, in fact, can be seen as an embodiment of modernity, as well as a reaction to it .

Turing’s Menagerie: Talking Lions, Virtual Bats, Electric Sheep and Analogical Peacocks: Common Ground and Common Interest are Necessary Components of Engagement

This theoretical paper attempts to define some of the key components and challenges required to create embodied conversational agents that can be genuinely interesting conversational partners. Wittgenstein’s argument concerning talking lions emphasizes the importance of having a shared common ground as a basis for conversational interactions. Virtual bats suggests that–for some people at least–it is important that there be a feeling of authenticity concerning a subjectively experiencing entity that can convey what it is like to be that entity. Electric sheep reminds us of the importance of empathy in human conversational interaction and that we should provide a full communicative repertoire of both verbal and non-verbal components if we are to create genuinely engaging interactions. Also we may be making the task more difficult rather than easy if we leave out non-verbal aspects of communication. Finally, analogical peacocks highlights the importance of between minds alignment and establishes a longer term goal of being interesting, creative, and humorous if an embodied conversational is to be truly an engaging conversational partner. Some potential directions and solutions to addressing these issues are suggested.

Individual factors and perceived community characteristics in relation to mental health and mental well-being

Background
It has been argued that though correlated with mental health, mental well-being is a distinct entity. Despite the wealth of literature on mental health, less is known about mental well-being. Mental health is something experienced by individuals, whereas mental well-being can be assessed at the population level. Accordingly it is important to differentiate the individual and population level factors (environmental and social) that could be associated with mental health and well-being, and as people living in deprived areas have a higher prevalence of poor mental health, these relationships should be compared across different levels of neighbourhood deprivation.

Methods
A cross-sectional representative random sample of 1,209 adults from 62 Super Output Areas (SOAs) in Belfast, Northern Ireland (Feb 2010 – Jan 2011) were recruited in the PARC Study. Interview-administered questionnaires recorded data on socio-demographic characteristics, health-related behaviours, individual social capital, self-rated health, mental health (SF-8) and mental well-being (WEMWBS). Multi-variable linear regression analyses, with inclusion of clustering by SOAs, were used to explore the associations between individual and perceived community characteristics and mental health and mental well-being, and to investigate how these associations differed by the level of neighbourhood deprivation.

Results
Thirty-eight and 30 % of variability in the measures of mental well-being and mental health, respectively, could be explained by individual factors and the perceived community characteristics. In the total sample and stratified by neighbourhood deprivation, age, marital status and self-rated health were associated with both mental health and well-being, with the ‘social connections’ and local area satisfaction elements of social capital also emerging as explanatory variables. An increase of +1 in EQ-5D-3 L was associated with +1SD of the population mean in both mental health and well-being. Similarly, a change from ‘very dissatisfied’ to ‘very satisfied’ for local area satisfaction would result in +8.75 for mental well-being, but only in the more affluent of areas.

Conclusions
Self-rated health was associated with both mental health and mental well-being. Of the individual social capital explanatory variables, ‘social connections’ was more important for mental well-being. Although similarities in the explanatory variables of mental health and mental well-being exist, socio-ecological interventions designed to improve them may not have equivalent impacts in rich and poor neighbourhoods.
