Review Meta AnalysisRadiofrequency denervation for neck and back pain. A systematic review of randomized controlled trials.
The diagnosis of cervical or lumbar zygapophyseal joint pain can only be made by using local anesthesia to block the nerves supplying the painful joint. There is a lack of effective treatment for chronic zygapophyseal joint pain or discogenic pain. Radiofrequency denervation appears to be an emerging technology, with substantial variation in its use between countries. ⋯ The selected trials provide limited evidence that radiofrequency denervation offers short-term relief for chronic neck pain of zygapophyseal joint origin and for chronic cervicobrachial pain; conflicting evidence on the short-term effect of radiofrequency lesioning on pain and disability in chronic low-back pain of zygapophyseal joint origin; and limited evidence that intradiscal radiofrequency thermocoagulation is not effective for chronic discogenic low-back pain. There is a need for further high-quality RCTs with larger patient samples and data on long-term effects, for which current evidence is inconclusive. Furthermore, RCTs are needed in non-spinal indications where radiofrequency denervation is currently used without any scientific evidence.

Review Meta AnalysisPsychological therapies for the management of chronic and recurrent pain in children and adolescents.
An increasing number of children suffer with pain that lasts for six months or longer. Traditional treatment for such pain has been pharmacological and/or physical. Increasingly, following developments in the field of adult chronic pain management, psychological therapies are being employed to treat children with chronic or recurrent pain. ⋯ There is very good evidence that psychological treatments, principally relaxation and cognitive behavioural therapy, are effective in reducing the severity and frequency of chronic headache in children and adolescents. There is at present no evidence for the effectiveness of psychological therapies in attenuating pain in conditions other than headache, and little evidence for the effectiveness of psychological therapies in improving non-pain outcomes.

Review Meta AnalysisCooling for newborns with hypoxic ischaemic encephalopathy.
Newborn animal and human pilot studies suggest that mild hypothermia following peripartum hypoxia-ischaemia in newborn infants may reduce neurological sequelae, without adverse effects. ⋯ Although two small randomised controlled trials demonstrated neither evidence of benefit or harm, current evidence is inadequate to assess either safety or efficacy of therapeutic hypothermia in newborn infants with hypoxic ischaemic encephalopathy. Therapeutic hypothermia for encephalopathic asphyxiated newborn infants should be further evaluated in well designed randomised controlled trials.

Review Meta AnalysisCot-nursing versus incubator care for preterm infants.
An optimal thermal environment is desirable for preterm infants. These infants are usually nursed in incubators, but cot-nursing may provide an alternative. Measures to assist the maintenance of body temperature for smaller infants in open cots include extra clothing/bedding, warming up the nursery and heating the cot mattress. Recently a heated water-filled mattress has been developed to maintain the temperature of a cot-nursed preterm infant. While there may be benefits of nursing preterm infants in open cots, there may be potential risks such as nosocomial infection caused by more handling due to easier access. ⋯ Due to the small numbers of trials included and infants studied, and the resulting imprecision in the measures of effect for all outcomes, the review does not give a clear indication for the role of cot-nursing for preterm infants. Further assessment of the role of cot nursing for preterm infants using randomised controlled trials is necessary.

ReviewNasal continuous positive airways pressure immediately after extubation for preventing morbidity in preterm infants.
Preterm infants being extubated following a period of intermittent positive pressure ventilation via an endotracheal tube are at risk of developing respiratory failure as a result of apnea, respiratory acidosis and hypoxia. Nasal continuous positive airway pressure appears to stabilise the upper airway, improve lung function and reduce apnea and may therefore have a role in facilitating extubation in this population. ⋯ nasal CPAP is effective in preventing failure of extubation in preterm infants following a period of endotracheal intubation and IPPV. Implication for research: further definition of the gestational age and weight groups in whom these results apply is required. Optimal levels of NCPAP as well as methods of administration remain to be determined.
