ReviewAripiprazole versus typical antipsychotic drugs for schizophrenia.
Aripiprazole is a relatively new antipsychotic drug, said to be the prototype of a new third generation of antipsychotics; the so-called dopamine-serotonin system stabilisers. In this review we examine how the efficacy and tolerability of aripiprazole differs from that of typical antipsychotics. ⋯ Aripiprazole differs little from typical antipsychotic drugs with respect to efficacy, however it presents significant advantages in terms of tolerability. Clearly reported pragmatic short, medium and long term randomised controlled trials are required to replicate and validate these findings and determine the position of aripiprazole in everyday clinical practice.

ReviewWITHDRAWN: Interventions for replacing missing teeth: surgical techniques for placing dental implants.
Many variations in the surgical technique for the placement of dental implants have been developed since the introduction of implant surgery into clinical practice. These include variations in the timing of implant placement in relation to the tooth removal, and variations in the way the recipient bone site is prepared, amongst others. ⋯ This review included studies evaluating the surgical techniques of two versus four implants to support a mandibular overdenture and crestal versus vestibular incision for implant placement. Based on the available results of RCTs, there is no strong evidence supporting superior success with one or other of the alternative techniques for either of these two aspects of surgical technique. These conclusions are based on a few RCTs for each aspect of surgical technique and some with relatively short follow-up periods and few patients.

ReviewHysterectomy versus hysterectomy plus oophorectomy for premenopausal women.
Prophylactic oophorectomy alongside hysterectomy in premenopausal women is common. The decision to remove or conserve the ovaries is often based on the perceived risk for ovarian cancer and the need for other additional gynaecological surgical interventions. The benefits or harms of prophylactic bilateral oophorectomy at the time of hysterectomy in premenopausal women are unknown. ⋯ The conclusions of this review are limited by the lack of data. More research of higher methodological quality is needed.

ReviewTacrolimus (FK506) for induction of remission in refractory ulcerative colitis.
There are a limited number of treatment options for patients with refractory ulcerative colitis. Animal models of inflammatory bowel disease and uncontrolled studies in humans suggest that tacrolimus may be effective treatment for ulcerative colitis. ⋯ Tacrolimus may be effective for short-term clinical improvement in patients with refractory ulcerative colitis. However, these results should be interpreted with caution due to the small number of patients enrolled in the trial and other study limitations. Insufficient treatment and follow-up intervals prevent any conclusions with regard to long term safety and efficacy. The use of tacrolimus in the clinical setting requires careful consideration of risks versus benefits as well as close monitoring for adverse events. More data from well designed and controlled studies are needed to determine the long-term efficacy and safety of tacrolimus.

ReviewPersonal assistance for adults (19-64) with physical impairments.
There is a high incidence of impairments among working age adults. Many countries offer personal assistance in the form of 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. 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 for particular people.
