Delirium is now the preferred term to describe acute confusional states. It is experienced by 10 to 30% of all hospital inpatients. Delirium is potentially reversible and is related to several adverse outcomes, including increased hospital length of stay, poor functional status, persistent cognitive impairment, need for institutional care and probably mortality. Disruption of the cholinergic system has been proposed as a key mechanism of delirium. Cholinesterase inhibitors enhance the cholinergic system and there have been reports that they might be beneficial in treating delirium. ⋯ There is currently no evidence from controlled trials that donepezil is effective in the treatment of delirium. Further trials using cholinesterase inhibitors for the treatment of delirium are needed.

ReviewOxcarbazepine in the maintenance treatment of bipolar disorder.
Some studies have suggested that oxcarbazepine has a role in preventing episode recurrence in bipolar affective disorder. This review attempted to investigate the existing evidence from randomised controlled trials for its use in the maintenance treatment of this illness. ⋯ There is an insufficient methodologically rigorous evidence base to provide guidance on the use of oxcarbazepine in the maintenance treatment of bipolar disorder. Given the need for more efficacious therapeutic agents, there is a need for good quality randomised controlled trials examining the therapeutic potential of this and related agents in bipolar disorder.

ReviewWITHDRAWN: Mefloquine for preventing malaria in non-immune adult travellers.
Mefloquine is commonly prescribed to prevent malaria in travellers, and has replaced other drugs because Plasmodium falciparum is commonly resistant to them. However, mefloquine may be associated with neuropsychiatric harmful effects. ⋯ Mefloquine prevents malaria, but has adverse effects that limit its acceptability . There is evidence from non-randomised studies that mefloquine has potentially harmful effects in tourists and business travellers, and its use needs to be carefully balanced against this. Trials of comparative effects of antimalarial prophylaxis should include episodes of malaria and withdrawal from prophylaxis as outcomes.

Metacarpophalangeal (MCP) arthroplasty with implants, which is the replacement of painful knuckle joints with artificial knuckle joints, has been performed for people with rheumatoid arthritis (RA) since the 1960s. The surgery is done because RA can cause damage of the knuckle joints making them unable to straighten out (flexion deformity) and causing them to lean over toward the small finger (flexion or ulnar deviation deformity). For eight to 12 weeks following surgery, patients wear hand splints and perform exercises to maintain and increase motion in the healing hand. Post-operative therapy regimes share common aims of encouraging MCP flexion and extension without the recurrence of flexion or ulnar deviation deformity. ⋯ Well-designed randomised controlled trials which compare the efficacy of different therapeutic splinting programmes following MCP arthroplasty are required. At this time, the results of one study (silver level evidence) suggest that continuous passive motion alone is not recommended for increasing motion or strength after MCP arthroplasty.

There is a high prevalence of impairments among people 65+, and the elderly population is increasing in the West. Many countries offer personal assistance, individualised support for people living in the community by a paid assistant other than a healthcare professional for at least 20 hours per week. ⋯ Research in this field is limited. Personal assistance is expensive and difficult to organise, especially in places that do not already have services in place. When implementing new programmes, recipients could be randomly assigned to different forms of assistance. While advocates may support personal assistance for myriad reasons, this review demonstrates that further studies are required to determine which models of personal assistance are most effective and efficient.
