ReviewInterventions for replacing missing teeth: bone augmentation techniques for dental implant treatment.
Dental implants require sufficient bone to adequately stabilise. For some patients implant treatment would not be an option without bone augmentation. A variety of materials and surgical techniques are available for use in bone augmentation. ⋯ There is no evidence from available RCTs supporting superior success with one or other of the alternative techniques examined. There was weak evidence that a non-resorbable membrane was better than no membrane for permitting bone growth about dental implants, and that a resorbable membrane over a bone graft may allow healing with fewer infections than a non-resorbable membrane.

ReviewEpinephrine for the resuscitation of apparently stillborn or extremely bradycardic newborn infants.
Epinephrine is a cardiac stimulant with complex effects on the heart and blood vessels. It has been used for decades in all age groups to treat cardiac arrest and bradycardia. Despite formal guidelines for the use of epinephrine in neonatal resuscitation, the evidence for these recommendations has not yet been rigorously scrutinised. While it is understood that this evidence is in large part derived from animal models and the adult human population, the contribution from work in the neonatal population remains unclear. In particular, it remains to be determined if any randomised studies in neonates have helped to establish if the administration of epinephrine in the context of apparent stillbirth or extreme bradycardia might influence mortality and morbidity. ⋯ We found no randomised, controlled trials evaluating the administration of epinephrine to the apparently stillborn or extremely bradycardic newborn infant. Similarly, we found no randomised, controlled trials which addressed the issues of optimum dosage and route of administration of epinephrine. Current recommendations for the use of epinephrine in newborn infants are based only on evidence derived from animal models and the human adult literature. Randomised trials in neonates are urgently required to determine the role of epinephrine in this population.

Nurses have expanded and developed their roles to meet the needs of patients. This review evaluates the safety, effectiveness and health outcomes of nurses practising in autonomous roles, using advanced practice skills, within the context of a dedicated bronchiectasis clinic. ⋯ This review has found one trial that does not demonstrate significant differences in clinical outcomes between nurse led care and doctor led care within the setting of a specialist clinic is, but there may be increased cost implications. Further research is required to review whether nurse led care provides the same outcomes in the community or secondary care setting.

The workplace has potential as a setting through which large groups of people can be reached to encourage smoking cessation. ⋯ We found 1. Strong evidence that interventions directed towards individual smokers increase the likelihood of quitting smoking. These include advice from a health professional, individual and group counselling and pharmacological treatment to overcome nicotine addiction. Self-help interventions are less effective. All these interventions are effective whether offered in the workplace or elsewhere. Although people taking up these interventions are more likely to stop, the absolute numbers who quit are low. 2. Limited evidence that participation in programmes can be increased by competitions and incentives organised by the employer. 3. Consistent evidence that workplace tobacco policies and bans can decrease cigarette consumption during the working day by smokers and exposure of non-smoking employees to environmental tobacco smoke at work, but conflicting evidence about whether they decrease prevalence of smoking or overall consumption of tobacco by smokers. 4. A lack of evidence that comprehensive approaches reduce the prevalence of smoking, despite the strong theoretical rationale for their use. 5. A lack of evidence about the cost-effectiveness of workplace programmes.

ReviewEarly intravenous nutrition for the prevention of neonatal jaundice.
The early institution of enteral feeding in the first few days of life is known to impact on the development of unconjugated hyperbilirubinaemia. However, the effect of early intravenous nutrition on neonatal jaundice remains unknown. ⋯ Decisions regarding the institution of early intravenous nutrition must continue to be based upon factors others than its effect on neonatal jaundice.
