A new primary dental care service compared with standard care for child and family to reduce the re-occurrence of childhood dental caries (Dental RECUR): study protocol for a randomised controlled trial

Background: In England and Scotland, dental extraction is the single highest cause of planned admission to the hospital for children under 11 years. Traditional dental services have had limited success in reducing this disease burden. Interventions based on motivational interviewing have been shown to impact positively dental health behaviours and could facilitate the prevention of re-occurrence of dental caries in this high-risk population. The objective of the study is to evaluate whether a new, dental nurse-led service, delivered using a brief negotiated interview based on motivational interviewing, is a more cost-effective service than treatment as usual, in reducing the re-occurrence of dental decay in young children with previous dental extractions. Methods/Design: This 2-year, two-arm, multicentre, randomised controlled trial will include 224 child participants, initially aged 5 to 7 years, who are scheduled to have one or more primary teeth extracted for dental caries under general anaesthesia (GA), relative analgesia (RA: inhalation sedation) or local anaesthesia (LA). The trial will be conducted in University Dental Hospitals, Secondary Care Centres or other providers of dental extraction services across the United Kingdom. The intervention will include a brief negotiated interview (based on the principles of motivational interviewing) delivered between enrolment and 6 weeks post-extraction, followed by directed prevention in primary dental care. Participants will be followed up for 2 years. The main outcome measure will be the dental caries experienced by 2 years post-enrolment at the level of dentine involvement on any tooth in either dentition, which had been caries-free at the baseline assessment. Discussion: The participants are a hard-to-reach group in which secondary prevention is a challenge. Lack of engagement with dental care makes the children and their families scheduled for extraction particularly difficult to recruit to an RCT. Variations in service delivery between sites have also added to the challenges in implementing the Dental RECUR protocol during the recruitment phase.

Anticipated regret to increase uptake of colorectal cancer screening in Scotland (ARTICS): Study protocol for a randomised controlled trial

Background: Colorectal cancer is the second leading cause of cancer deaths in the UK. Screening is key to early detection. The Scottish programme of colorectal cancer screening is running successfully, and involves all adults aged between 50 and 74 years being invited to post back a faecal sample for testing every 2 years. However, screening uptake is sub-optimal: for example rates for the period November 2009 to October 2011 ranged from just 39% for males living in the most deprived areas to 67% for least deprived females. Recent research has shown that asking people to consider the emotional consequences of not participating in screening (anticipated regret) can lead to a significant increase in screening uptake. Methods/Design: We will test a simple anticipated regret manipulation, in a large randomised controlled trial with 60,000 members of the general public. They will be randomly allocated to one of 3 arms, no questionnaire, control questionnaire or anticipated regret questionnaire. The primary outcome will be screening test kit return. Results will also be examined by demographic variables (age, gender, deprivation) as these are currently related to screening kit return. Discussion: If this anticipated regret intervention leads to a significant increase in colorectal cancer screening kit returns, this would represent a rare example of a theoretically-driven, simple intervention that could result in earlier detection of colorectal cancer and many more lives saved.

Functional Disorders in Neurology: Case Studies

Functional, often called psychogenic, disorders are common in neurological practice. We illustrate clinical issues and highlight some recent research findings using six case studies of functional neurological disorders. We discuss dizziness as a functional disorder, describing the relatively new consensus term Persistent Posturo-Perceptual Dizziness (PPPD), axial jerking/myoclonus as a functional movement disorder, functional speech symptoms, post-concussion disorder with functional cognitive symptoms and finally advances in treatment of dissociative seizures and functional motor disorders

Doomed to fail:the persistent search for a modernist mental health nurse identity

The perennial issue of the distinctiveness of the mental health nurse (MHN) is once again to the fore. Previous attempts to resolve this apparent identity crisis in the discipline have included proposals for new models, new research and new educational preparation as well as new alliances, and new ways of practising. Now the politically driven concept of the generic nurse is gaining enough momentum to potentially end the discussion once and for all.This paper takes a postmodernist approach to MHN identity that questions the requirement for MHNs to articulate their distinctiveness, and offers alternative constructions of this identity to those promulgated by policy makers and by other health disciplines
