Mass media tobacco control campaigns can reach large numbers of people. Much of the literature is focused on the effects of tobacco control advertising on young people, but there are also a number of evaluations of campaigns targeting adult smokers, which show mixed results. Campaigns may be local, regional or national, and may be combined with other components of a comprehensive tobacco control policy. ⋯ There is evidence that comprehensive tobacco control programmes which include mass media campaigns can be effective in changing smoking behaviour in adults, but the evidence comes from a heterogeneous group of studies of variable methodological quality. One state-wide tobacco control programme (Massachusetts) showed positive results up to eight years after the campaign, while another (California) showed positive results only during the period of adequate funding and implementation. Six of nine studies carried out in communities or regions showed some positive effects on smoking behaviour and at least one significant change in smoking prevalence (Sydney). The intensity and duration of mass media campaigns may influence effectiveness, but length of follow up and concurrent secular trends and events can make this difficult to quantify. No consistent relationship was observed between campaign effectiveness and age, education, ethnicity or gender.

ReviewWITHDRAWN: Home-based support for disadvantaged teenage mothers.
Babies born to socio-economically disadvantaged mothers are at higher risk of injury, abuse or neglect and health problems than babies born to more affluent mothers; disadvantaged teenage mothers are at particular risk of adverse outcomes. Home-visiting programs are thought to improve outcomes for both mothers and children, largely through advice and support. ⋯ This review suggests there is only limited evidence that home-visiting programmes of the kind described in this review can impact positively on the quality of parenting of teenage mothers or on child development outcomes for their offspring. For reasons discussed in the review, this does not amount to a conclusion that home-visiting programmes are ineffective but indicates a need to think carefully about the problems that home visiting might influence and about improvements in the conduct and reporting of outcome studies in this area.

ReviewOxcarbazepine in the maintenance treatment of bipolar disorder.
Some studies have suggested that oxcarbazepine has a role in preventing episode recurrence in bipolar affective disorder. This review attempted to investigate the existing evidence from randomised controlled trials for its use in the maintenance treatment of this illness. ⋯ There is an insufficient methodologically rigorous evidence base to provide guidance on the use of oxcarbazepine in the maintenance treatment of bipolar disorder. Given the need for more efficacious therapeutic agents, there is a need for good quality randomised controlled trials examining the therapeutic potential of this and related agents in bipolar disorder.

Epilepsy is a common serious neurological condition with a 0.5% prevalence. As a result of the perceived deficiencies and suggestions to improve the quality of care offered to people with epilepsy, two models of service provision have been suggested by researchers: specialist epilepsy out-patient clinics (as opposed to the management of patients in general neurology clinics or general medical clinics) and nurse-based liaison services between primary (GP) and secondary/tertiary (hospital-based) care. ⋯ It is clearly plausible that specialist epilepsy nurses could improve quality in epilepsy care. However, there is as yet little evidence to support this assumption as the present research base is small. Further research is needed to investigate the effectiveness of specialist epilepsy nurses before such recommendations can be made.

Metacarpophalangeal (MCP) arthroplasty with implants, which is the replacement of painful knuckle joints with artificial knuckle joints, has been performed for people with rheumatoid arthritis (RA) since the 1960s. The surgery is done because RA can cause damage of the knuckle joints making them unable to straighten out (flexion deformity) and causing them to lean over toward the small finger (flexion or ulnar deviation deformity). For eight to 12 weeks following surgery, patients wear hand splints and perform exercises to maintain and increase motion in the healing hand. Post-operative therapy regimes share common aims of encouraging MCP flexion and extension without the recurrence of flexion or ulnar deviation deformity. ⋯ Well-designed randomised controlled trials which compare the efficacy of different therapeutic splinting programmes following MCP arthroplasty are required. At this time, the results of one study (silver level evidence) suggest that continuous passive motion alone is not recommended for increasing motion or strength after MCP arthroplasty.
