ReviewMaintenance therapy with oxytocin antagonists for inhibiting preterm birth after threatened preterm labour.
In some women, an episode of preterm labour settles and does not result in immediate preterm birth. Subsequent treatment with tocolytic agents such as oxytocin receptor antagonists may then have the potential to prevent the recurrence of preterm labour, prolonging gestation, and preventing the adverse consequences of prematurity for the infant. ⋯ There is insufficient evidence to support the use of oxytocin receptor antagonists to inhibit preterm birth after a period of threatened or actual preterm labour. Any future trials using oxytocin antagonists or other drugs as maintenance therapy for preventing preterm birth should examine a variety of important infant outcome measures, including reduction of neonatal morbidity and mortality, and long-term infant follow up. Future research should also focus on the pathophysiological pathways that precede preterm labour.

ReviewSedation versus general anaesthesia for provision of dental treatment in under 18 year olds.
A significant proportion of children have caries requiring restorations or extractions, and some of these children will not accept this treatment under local anaesthetic. Historically this has been managed in children by use of a general anaesthetic; however use of sedation may lead to reduced morbidity and cost. The aim of this review is to compare the efficiency of sedation versus general anaesthesia for the provision of dental treatment for children and adolescents under 18 years. ⋯ Randomized controlled studies comparing the use of dental general anaesthesia with sedation to quantify differences such as morbidity and cost are required.

Review Comparative StudyIntrarectal quinine versus intravenous or intramuscular quinine for treating Plasmodium falciparum malaria.
In children with falciparum malaria, a proprietary quinine preparation (adjusted to make it less acidic) administered rectally may be easier to use and less painful than intramuscular or intravenous administration. However, rectal quinine may be less effective. ⋯ We detected no difference in the effect on parasites and clinical illness for intrarectal quinine, but most trials were small. Pain may be less with intrarectal proprietary, buffered quinine preparations (made less acidic by adjustment of the pH to 4.5). Further larger trials in patients with severe malaria and in adults are required before the intrarectal route can be recommended.

Hypothermia has been used in the treatment of head injury for many years. Encouraging results from small trials and laboratory studies led to renewed interest in the area and some larger trials. ⋯ Hypothermia may be effective in reducing death and unfavourable outcomes for traumatic head injured patients, but significant benefit was only found in low quality trials. Low quality trials have a tendency to overestimate the treatment effect. The high quality trials found some statistically non-significant benefit of hypothermia which could be due to the play of chance. Hypothermia may increase the risk of pneumonia. Due to uncertainties in its effects, hypothermia should only be given to patients taking part in a randomised controlled trial with good allocation concealment.

Review Meta AnalysisSingle dose oral paracetamol (acetaminophen) with codeine for postoperative pain in adults.
This is an updated version of the Cochrane review published in Issue 4, 1998. Combining drugs from different classes with different modes of action may offer opportunity to optimise efficacy and tolerability, using lower doses of each drug to achieve the same degree of pain relief. Previously we concluded that addition of codeine to paracetamol provided additional pain relief, but at expense of additional adverse events. New studies have been published since. This review sought to evaluate efficacy and safety of paracetamol plus codeine using current data, and compare findings with other analgesics evaluated similarly. ⋯ This update confirms previous findings that combining paracetamol with codeine provided clinically useful levels of pain relief in about 50% of patients with moderate to severe postoperative pain, compared with under 20% with placebo. New information for remedication shows that the combination extended the duration of analgesia by about one hour compared to treatment with the same dose of paracetamol alone. At higher doses, more participants experienced adequate pain relief, but the amount of information available for the 1000 mg paracetamol plus 60 mg codeine dose was small, and based on limited information.
