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.

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.

Supported decision making: a review of the international literature

Supported decision making (SDM) refers to the process of supporting people, whose decision making ability may be impaired, to make decisions and so promote autonomy and prevent the need for substitute decision making. There have been developments in SDM but mainly in the areas of intellectual disabilities and end-of-life care rather than in mental health. The main aim of this review was to provide an overview of the available evidence relevant to SDM and so facilitate discussion of how this aspect of law, policy and practice may be further developed in mental health services. The method used for this review was a Rapid Evidence Assessment which involved: developing appropriate search strategies; searching relevant databases and grey literature; then assessing, including and reviewing relevant studies. Included studies were grouped into four main themes: studies reporting stakeholders’ views on SDM; studies identifying barriers to the implementation of SDM; studies highlighting ways to improve implementation; and studies on the impact of SDM. The available evidence on implementation and impact, identified by this review, is limited but there are important rights-based, effectiveness and pragmatic arguments for further developing and researching SDM for people with mental health problems.

Fabricated or Induced Illness in Children: A Narrative Review of the Literature

Although child maltreatment due to abuse or neglect is pervasive within our society, less
is known about fabricated or induced illness by carers (FII), which is considered to be a
rare form of child abuse. FII occurs when a caregiver (in 93% of cases, the mother)
misrepresents the child as ill either by fabricating, or much more rarely, producing
symptoms and then presenting the child for medical care, disclaiming knowledge of the
cause of the problem. The growing body of literature on FII reflects the lack of clarity
amongst professionals as to what constitutes FII, the difficulties involved in diagnosis,
and the lack of research into psychotherapeutic intervention with perpetrators. This lack
of clarity further complicates the identification, management and treatment of children
suffering from FII and may result in many cases going undetected, with potentially lifethreatening
consequences for children. It has been suggested that there is a national
under-reporting of fabricated or induced illness. In practice these cases are encountered
more frequently due to the chronic nature of the presentations, the large number of
professionals who may be involved and the broad spectrum including milder cases that
may not all require a formal child protection response. Diagnosis of fabricated disease
can be especially difficult, because the reported signs and symptoms cannot be confirmed
(when they are being exaggerated or imagined) or may be inconsistent (when they are
induced or fabricated). This paper highlights and discusses the controversies and
complexities of this condition, the risks to the child and how it affects children; the
paucity of systematic research regarding what motivates mothers to harm their children
by means of illness falsification; how the condition should be managed and treated for
both mother and child; and implications for policy and practice.
