ReviewAntibiotic prophylaxis in clean and clean-contaminated ear surgery.
Ear surgery may be performed in the treatment of chronic otitis media, ossicular chain disorders, tympanic membrane perforations and otitis media with effusion. Postoperative infection in ear surgery may result in: Wound infections Infection of the middle ear or mastoid resulting in discharge from the ear canal Failure of the tympanic membrane to close Labyrinthitis due to infection in, or adjacent to, the inner ear These complications may be associated with discomfort and inconvenience for the patient, an increase in morbidity and an increase in the costs of medical care. ⋯ There is no strong evidence that the large scale use of prophylactic of antibiotics in clean and clean-contaminated ear surgery is helpful in reducing postoperative complications such as wound infection, discharge from the outer ear canal, labyrinthitis and graft failure.

Spinal cord stimulation (SCS) is a form of therapy used to treat certain types of chronic pain. It involves an electrical generator that delivers pulses to a targeted spinal cord area. The leads can be implanted by laminectomy or percutaneously and the source of power is supplied by an implanted battery or by an external radio-frequency transmitter. The exact mechanism of action of SCS is poorly understood. ⋯ Although there is limited evidence in favour of SCS for Failed Back Surgery Syndrome and Complex Regional Pain Syndrome Type I, more trials are needed to confirm whether SCS is an effective treatment for certain types of chronic pain. In addition, there needs to be a debate about trial designs that will provide the best evidence for assessing this type of intervention.

Review Meta AnalysisPalliation of metastatic bone pain: single fraction versus multifraction radiotherapy - a systematic review of the randomised trials.
Recent randomised studies reported that single fraction radiotherapy was as effective as multifraction radiotherapy in relieving pain due to bone metastasis. However, there are concerns about the higher re-treatment rates and the efficacy of preventing future complications such as pathological fracture and spinal cord compression by single fraction radiotherapy. ⋯ Single fraction radiotherapy was as effective as multifraction radiotherapy in relieving metastatic bone pain. However, the re-treatment rate and pathological fracture rates were higher after single fraction radiotherapy. Studies with quality of life and health economic end points are warranted to find out the optimal treatment option.

Wound and bone infections are frequently associated with open fractures of the extremities and may add significantly to the resulting morbidity. The administration of antibiotics is routinely used in developed countries as an adjunct to a comprehensive management protocol that also includes irrigation, surgical debridement and stabilisation when indicated, and is thought to reduce the frequency of infections. ⋯ Antibiotics reduce the incidence of early infections in open fractures of the limbs. Further placebo controlled randomised trials are unlikely to be justified in middle and high income countries. Further research is necessary to the determine the avoidable burden of morbidity in countries where antibiotics are not used routinely in the management of open fractures.

ReviewNaloxone for preventing morbidity and mortality in newborn infants of greater than 34 weeks' gestation with suspected perinatal asphyxia.
Studies in animal models have suggested that naloxone, a specific opiate antagonist, may improve outcomes for newborn infants with perinatal asphyxia. ⋯ There are insufficient data available to evaluate the safety and effectiveness of the routine use of naloxone for newborn infants of greater than 34 weeks' gestation with suspected perinatal asphyxia. A further randomised controlled trial is needed to determine if naloxone benefits newborn infants with suspected perinatal asphyxia. Such a trial should assess clinically important outcomes such as mortality, and adverse short and long term neurological outcomes.
