Endodontic 'solutions' part 1:A literature review on the use of endodontic lubricants, irrigants and medicaments

Endodontic lubricants, irrigants and medicaments help prepare and disinfect root canal systems (RCS) but primary and secondary cases involve different microbes and therefore it is unlikely that one protocol will be effective for both case types. Each individual 'solution' or sequence of 'solutions' could play a significant role in each case type, but there are no detailed published guidelines in existence. To help inform clinical practice it was decided to undertake a literature review followed by a UK and Republic of Ireland wide audit on current endodontic 'solution' usage within dental schools. The literature review was undertaken under the following headings: pre-op oral rinse; file lubricants; root canal irrigants and intracanal medicaments and provides an evidence base for protocol development for both primary and retreatment cases. The audit project and the protocols developed from the findings of both the literature review and audit will be presented in Part 2.

Race, space and politics in Mid-Victorian Ireland: the ethnologies of Abraham Hume and John McElheran

There has been much scholarly debate about the significance and influence of racialist thinking in the political and cultural history of nineteenth-century Ireland. With reference to that ongoing historiographical discussion, this paper considers the racial geographies and opposing political motivations of two Irish ethnologists, Abraham Hume and John McElheran, using their racialist regimes to query some of the common assumptions that have informed disagreements over the role and reach of racial typecasting in mid-nineteenth-century Ireland. As well as examining in detail the racial imaginaries promulgated by Hume and McElheran, the paper also argues for the importance of situating racialist discourse in the spaces in which it was communicated and contested. Further, in highlighting the ways in which Hume and McElheran collapsed together race, class and religion, the paper troubles the utility of a crisp analytical distinction between those disputed categories.

Paranoia and self-concepts in psychosis: A systematic review of the literature.

The purpose of the present study was to review systematically, research exploring the relationship between self-concepts and paranoia in psychosis. A literature search was performed by two independent raters in relevant databases (MedLine, PsychInfo and Web of Science) and articles meeting the inclusion criteria were cross-referenced. Following scrutiny according to inclusion criteria, 18 studies were selected for review. A narrative synthesis of findings, in which methodological variability is discussed, is presented relative to three key areas: the nature of the relationship between paranoia and self-concepts; the association between paranoia and discrepancies in self-concepts; the nature of the relationship between paranoia and self-concepts when other, dimensional aspects of these constructs are taken into account. The systematic literature review indicated relatively consistent findings, that paranoia is associated with more negative self-concepts when measured cross-sectionally. Results are somewhat more mixed in regards to research on paranoia and self-concept discrepancies. Studies investigating dimensional aspects of self-concepts and paranoia yield findings of particular interest, especially in regards to the association indicated between instability of self-concepts and paranoia. Limitations in research and of the present systematic review are discussed. Clinical and theoretical implications of findings are outlined and possible directions for future research are suggested.

Adherence to oral chemotherapy: a review of the literature

Oncology is rapidly changing. Over the past few years there has been an increase in the number of patients receiving oral chemotherapy, which is often administered as tablets away from the hospital setting and in the absence of direct health professional support. This situation places onus on patients to not only administer their medication, but also to report any deterioration in their health. Medication adherence in oral chemotherapy is therefore a major concern. This article examines medication adherence for people receiving oral chemotherapy and the importance of concordant communication practices.

Catholics, Science and Civic Culture in Victorian Belfast

The connections between science and civic culture in the Victorian period have been extensively, and intensively, investigated over the past several decades. Limited attention, however, has been paid to Irish urban contexts. Roman Catholic attitudes towards science in the nineteenth century have also been neglected beyond a rather restricted set of thinkers and topics. This paper is offered as a contribution to addressing these lacunae, and examines in detail the complexities involved in Catholic engagement with science in Victorian Belfast. The political and civic geographies of Catholic involvement in scientific discussions in a divided town are uncovered through an examination of five episodes in the unfolding history of Belfast's intellectual culture. The paper stresses the importance of attending to the particularities of local politics and scientific debate for understanding the complex realities of Catholic appropriations of science in a period and urban context profoundly shaped by competing political and religious factions. It also reflects more generally on how the Belfast story supplements and challenges scholarship on the historical relations between Catholicism and science.
