ReviewInterventions for replacing missing teeth: maintaining health around dental implants.
To maintain healthy tissues around dental implants it is important to institute an effective preventive regimen (supportive therapy). Different maintenance regimens have been suggested, however it is unclear which are the most effective. ⋯ There is only little reliable evidence for which are the most effective interventions for maintaining health around peri-implant tissues. There was no evidence that the use of powered or sonic toothbrushes was superior to manual toothbrushing. There is weak evidence that Listerine mouthwash, used twice a day for 30 seconds, as adjunct to routine oral hygiene is effective in reducing plaque formation and marginal bleeding around implants. There was no evidence that phosphoric etching gel offered any clinical advantage over mechanical debridement. These findings are based on RCTs having short follow-up periods and few subjects. There is not any reliable evidence for the most effective regimens for long term maintenance. More RCTs should be conducted in this area. In particular, there is a definite need for trials powered to find possible differences, using primary outcome measures and with much longer follow up. Such trials should be reported according the CONSORT guidelines (http://www.consort-statement.org/).

ReviewRadiofrequency thermal ablation versus other interventions for hepatocellular carcinoma.
Hepatocellular carcinoma is one of the most common malignant diseases worldwide. A potential curative option is surgical resection. Due to impaired liver function and/or anatomical reasons only few patients can be treated surgically. For the majority of patients, several interventions have been developed. Among these, local radiofrequency inducing heat production has been used to coagulate the cancer. ⋯ Radiofrequency thermal ablation seems a potentially promising technique for the treatment of small hepatocellular carcinoma. However, more randomised clinical trials are needed.

ReviewInterventions for isolated diaphyseal fractures of the ulna in adults.
Isolated fractures of the shaft of the ulna, which are often sustained when the forearm is raised to shield against a blow, are generally treated on an out-patient basis. ⋯ There is insufficient evidence from randomised trials to determine which method of treatment is the most appropriate for isolated fractures of the ulnar shaft in adults. There is a need to establish the incidence of this injury and the outcome and associated costs of the various forms of treatment. Well designed randomised trials of current forms of conservative treatment are recommended.

Review Meta AnalysisProstaglandins for prevention of postpartum haemorrhage.
Prostaglandins have mainly been used for postpartum haemorrhage when other measures fail. Misoprostol, a new and inexpensive prostaglandin E1 analogue, has been suggested as an alternative for routine management of the third stage of labour. ⋯ Neither intramuscular prostaglandins nor misoprostol are preferable to conventional injectable uterotonics as part of the active management of the third stage of labour especially for low-risk women. Future research on prostaglandin use after birth should focus on the treatment of postpartum haemorrhage rather than prevention where they seem to be more promising.

ReviewSucrose for analgesia in newborn infants undergoing painful procedures.
Management of pain for neonates is less than optimal. The administration of sucrose with and without non-nutritive sucking (pacifiers) has been the most frequently studied non-pharmacological intervention for relief of procedural pain in neonates. ⋯ Sucrose is safe and effective for reducing procedural pain from single painful events (heel lance, venepuncture). There was inconsistency in the dose of sucrose that was effective (dose range of 0.012 g to 0.12 g), and therefore an optimal dose to be used in preterm and/or term infants could not be identified. The use of repeated administrations of sucrose in neonates needs to be investigated as does the use of sucrose in combination with other behavioural (e.g., facilitated tucking, kangaroo care) and pharmacologic (e.g., morphine, fentanyl) interventions. Use of sucrose in neonates who are of very low birth weight, unstable and/or ventilated also needs to be addressed.
