ReviewSurgical versus non-surgical treatment for carpal tunnel syndrome.
Carpal tunnel syndrome results from entrapment of the median nerve in the wrist. Common symptoms are tingling, numbness, and pain in the hand that may radiate to the forearm or shoulder. Surgical treatment is widely preferred to non-surgical or conservative therapies for people who have overt symptoms, while mild cases are usually not treated. ⋯ Surgical treatment of carpal tunnel syndrome relieves symptoms significantly better than splinting. Further research is needed to discover whether this conclusion applies to people with mild symptoms.

Colloids are widely used in the replacement of fluid volume. However doubts remain as to which colloid is best. Different colloids vary in their molecular weight and therefore in the length of time they remain in the circulatory system. Because of this and their other characteristics, they may differ in their safety and efficacy. ⋯ From this review, there is no evidence that one colloid solution is more effective or safe than any other, although the confidence intervals are wide and do not exclude clinically significant differences between colloids. Larger trials of fluid therapy are needed if clinically significant differences in mortality are to be detected or excluded.

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.

Alzheimer's disease, vascular and mixed dementia are the commonest forms of dementia in older people. There is evidence that the excitatory activity of L-glutamate plays a role in the pathogenesis of Alzheimer's disease and in the damage from an ischaemic stroke. A low affinity antagonist to N-Methyl-D-aspartate (NMDA) type receptors, such as memantine, may prevent excitatory amino acid neurotoxicity without interfering with the physiological actions of glutamate required for memory and learning. ⋯ Memantine is a safe drug and may be useful for treating Alzheimer's, vascular,and mixed dementia of all severities. Most of the trials so far reported have been small and not long enough to detect clinically important benefits. However there is a possible benefit on cognition and global measures, and an early improvement in behaviour in people with dementia. More studies are needed.

Review Meta AnalysisTopical fluoride (toothpastes, mouthrinses, gels or varnishes) for preventing dental caries in children and adolescents.
Topical fluoride therapy (TFT) in the form of varnish, gel, mouthrinse or toothpaste has been used extensively as a caries-preventive intervention for over three decades. ⋯ The benefits of topical fluorides have been firmly established on a sizeable body of evidence from randomized controlled trials. While the formal examination of sources of heterogeneity between studies has been important in the overall conclusions reached, these should be interpreted with caution. We were unable to reach definite conclusions about any adverse effects that might result from the use of topical fluorides, because data reported in the trials are scarce.
