Review Meta AnalysisShort versus standard duration oral antibiotic therapy for acute urinary tract infection in children.
The optimal duration of oral antibiotic therapy for urinary tract infection (UTI) in children has not been determined. A number of studies have compared single dose therapy to standard therapy for UTI, with mixed results. A course of antibiotics longer than a single dose but shorter than the usual 7-10 days might decrease the relapse rate and still provide some of the benefits of a shortened course of antibiotics. ⋯ A 2-4 day course of oral antibiotics appears to be as effective as 7-14 days in eradicating lower tract UTI in children.

ReviewConservative interventions for treating distal radial fractures in adults.
Fracture of the distal radius is a common clinical problem particularly in elderly white women with osteoporosis. ⋯ There remains insufficient evidence from randomised trials to determine which methods of conservative treatment are the most appropriate for the more common types of distal radial fractures in adults. Therefore, at present, practitioners applying conservative management should use an accepted technique with which they are familiar, and which is cost-effective from the perspective of their provider unit. Patient preferences and circumstances, and the risk of complications should also be considered. Prioritising research questions to clarify the most appropriate conservative treatment for this common fracture is warranted. Researchers should differentiate between extra-articular and intra-articular, and non-displaced and displaced fractures, ascertain patient preferences, and agree a core outcome data set.

Nausea and vomiting are the most common symptoms experienced in early pregnancy, with nausea affecting between 70 and 85% of women. About half of pregnant women experience vomiting. ⋯ Anti-emetic medication appears to reduce the frequency of nausea in early pregnancy. There is some evidence of adverse effects, but there is very little information on effects on fetal outcomes from randomised controlled trials. Of newer treatments, pyridoxine (vitamin B6) appears to be more effective in reducing the severity of nausea. The results from trials of P6 acupressure are equivocal. No trials of treatments for hyperemesis gravidarum show any evidence of benefit. Evidence from observational studies suggests no evidence of teratogenicity from any of these treatments.

Review Meta AnalysisFluoride mouthrinses for preventing dental caries in children and adolescents.
Fluoride mouthrinses have been used extensively as a caries-preventive intervention in school-based programmes and individually at home. ⋯ This review suggests that the supervised regular use of fluoride mouthrinse at two main strengths and rinsing frequencies is associated with a clear reduction in caries increment in children. In populations with caries increment of 0.25 D(M)FS per year, 16 children will need to use a fluoride mouthrinse (rather than a non-fluoride rinse) to avoid one D(M)FS; in populations with a caries increment of 2.14 D(M)FS per year, 2 children will need to rinse to avoid one D(M)FS. There is a need for complete reporting of side effects and acceptability data in fluoride mouthrinse trials.

ReviewTranscranial magnetic stimulation for the treatment of obsessive-compulsive disorder.
Transcranial magnetic stimulation (TMS) was introduced as a neurophysiological technique in 1985 when Anthony Barker and his team developed a compact machine that permitted non-invasive stimulation of the cerebral cortex (Barker 1985). Since its introduction, TMS has been used to evaluate the motor system, to study the function of several cerebral regions, and for the pathophysiology of several neuropsychiatric illnesses. In addition, it has been suggested that TMS might have therapeutic potential. Some controlled studies have evaluated the effects of repetitive TMS (rTMS) in patients with obsessive-compulsive disorder (OCD). Greenberg (Greenberg 1997) observed that a single session of right prefrontal cortex stimulation produced a significant decrease in compulsive urges in OCD patients lasting over eight hours. Other studies have reported transitory improvements in mood but there are no observations for changes in anxiety or obsessions. ⋯ There are currently insufficient data from randomised controlled trials to draw any conclusions about the efficacy of transcranial magnetic stimulation in the treatment of obsessive-compulsive disorder.
