Tinnitus is described as the perception of sound or noise in the absence of real acoustic stimulation. It has been compared with chronic pain, and may be associated with depression or depressive symptoms which can affect quality of life and the ability to work. Antidepressant drugs have been used to treat tinnitus in patients with and without depressive symptoms. ⋯ There is insufficient evidence to say that antidepressant drug therapy improves tinnitus.

ReviewSpeed enforcement detection devices for preventing road traffic injuries.
It is estimated that by 2020, road traffic crashes will have moved from ninth to third in the world ranking of burden of disease, as measured in disability adjusted life years. The identification of effective strategies for the prevention of road traffic injuries is of global public health importance. Measures aimed at reducing traffic speed are considered essential to preventing road injuries; the use of speed enforcement detection devices (including speed cameras and radar and laser devices) is one such measure. ⋯ Despite the methodological limitations of the studies reviewed, the consistency of reported positive reductions in speed and crash outcomes across all studies suggest that SEDs are a promising intervention for reducing the number of road traffic injuries and deaths. More studies of a scientifically rigorous nature are necessary to provide a stronger evidence base that these interventions are worthwhile. There is a need for international harmonisation of data collection methods, including standards on how best to measure speeds and collect crash data, over lengthy intervention and follow-up periods, as well as some consensus as to the expression of outcomes in studies, so that studies can be compared.

ReviewInterventions for ear discharge associated with grommets (ventilation tubes).
The insertion of grommets (also known as ventilation or tympanostomy tubes) is one of the most common surgical procedures performed on children. Postoperative otorrhoea (discharge) is the most common complication with a reported incidence ranging from 10% to 50%. In the UK, many ENT surgeons treat with topical antibiotics/steroid combinations, but general practitioners, mainly through fears of ototoxicity, are unlikely to prescribe these and choose systemic broad-spectrum antibiotics. ⋯ The authors of this review have been unable to identify the most effective intervention or to assess the associated risks. Research is urgently needed into the effectiveness of oral versus topical antibiotics in this group of patients. Clinicians considering antibiotic treatment need to balance any potential benefit against the risks of side effects and antibiotic resistance.

ReviewReplacement arthroplasty versus internal fixation for extracapsular hip fractures in adults.
Internal fixation, commonly used for extracapsular hip fractures, may fail particularly in unstable fractures. Replacement of the hip using arthroplasty, often used for intracapsular fractures, has been used as an alternative. ⋯ There is insufficient evidence from randomised trials to determine whether replacement arthroplasty has any advantage over internal fixation for extracapsular hip fractures. Further larger well-designed randomised trials comparing arthroplasty versus internal fixation for the treatment of unstable fractures are required.

ReviewExternal cephalic version for breech presentation before term.
External cephalic version (ECV) of the breech fetus at term (after 37 weeks) has been shown to be effective in reducing the number of breech presentations and caesarean sections, but the rates of success are relatively low. This review examines studies initiating ECV prior to term (before 37 weeks' gestation). ⋯ Compared with no ECV attempt, ECV commenced before term reduces non-cephalic births. Compared with ECV at term, beginning ECV at between 34 to 35 weeks may have some benefit in terms of decreasing the rate of non-cephalic presentation, and caesarean section. Further trials are needed to confirm this finding and to rule out increased rates of preterm birth, or other adverse perinatal outcomes. A large pragmatic trial is ongoing (www.utoronto.ca/miru/eecv2).
