Primary postpartum haemorrhage is one of the top five causes of maternal mortality in both developed and developing countries. ⋯ Rectal misoprostol in a dose of 800 micrograms could be a useful 'first line' drug for the treatment of primary postpartum haemorrhage. Further randomised controlled trials are required to identify the best drug combinations, route, and dose for the treatment of postpartum haemorrhage.

ReviewCare home versus hospital and own home environments for rehabilitation of older people.
Rehabilitation for older people has acquired an increasingly important profile for both policy-makers and service providers within health and social care agencies. This growing demand for rehabilitation services has generated an increased interest in the use of alternative care environments, for example care home environments, for older persons' rehabilitation. At a time when there is pressure for policy decision-makers and service providers to explore the use of such care settings for the provision of rehabilitation for older people, there appears limited evidence on which to base decisions. ⋯ There is insufficient evidence to compare the effects of care home environments, hospital environments and own home environments on older persons rehabilitation outcomes. Although the authors acknowledge that absence of effect is not no effect. There are three main reasons; the first is that the description and specification of the environment is often not clear; secondly, the components of the rehabilitation system within the given environments are not adequately specified and; thirdly, when the components are clearly specified they demonstrate that the control and intervention sites are not comparable with respect to the methodological criteria specified by Cochrane EPOC group (Cochrane 1998). The combined effect of these factors resulted in the comparability between intervention and control groups being very weak. For example, there were differences in the services provided in the intervention and control arms, due possibly to differences in dominant remuneration systems, nature of the rehabilitation transformation, patient characteristics, skill mix and academic status of the care environment.

Bone metastases manifest through pain, which can arise even before the injury is radiologically detected. Pain occurs as a result of bone destruction and, as more destruction ensues, more pain can be experienced. Radiculopathies, plexopathies and shrinkage of spinal nerves due to tumour growth and fractures are very frequent in these patients. Relief of pain from bone metastasis can be achieved by treating the cancer itself; radiotherapy; conventional analgesics; and specific drugs that work on the bone tumour-induced alteration: biphosphonates, calcitonin or radioactive agents. ⋯ The efficacy of radioisotopes has been assessed in clinical trials with small sample sizes and short-term evaluations of the outcomes. There is some evidence indicating that radioisotopes may give complete reduction in pain over one to six months with no increase in analgesic use, but adverse effects, specifically leukocytopenia and thrombocytopenia, have also been experienced.

ReviewAntibiotics to prevent complications following dental implant treatment.
Some dental implant failures may be due to bacterial contamination at implant insertion. Infections around biomaterials are difficult to treat and almost all infected implants have to be removed. In general, antibiotic prophylaxis in surgery is only indicated for patients at risk of infectious endocarditis, for patients with reduced host-response, when surgery is performed in infected sites, in cases of extensive and prolonged surgical interventions and when large foreign materials are implanted. To minimise infections after dental implant placement various prophylactic systemic antibiotic regimens have been suggested. More recent protocols recommended short term prophylaxis, if antibiotics have to be used. With the administration of antibiotics adverse events may occur, ranging from diarrhoea to life-threatening allergic reactions. Another major concern associated with the widespread use of antibiotics is the selection of antibiotic-resistant bacteria. The use of antibiotics in implant dentistry is controversial. It would be useful to know whether prophylactic antibiotics are effective in reducing failures of dental implants. ⋯ There is not appropriate scientific evidence to recommend or discourage the use of prophylactic systemic antibiotics to prevent complications and failures of dental implants. Even though the present review did not assess the effectiveness of prophylactic antibiotics for patients at risk for endocarditis, it seems sensible to recommend the use of prophylactic antibiotics for patients at high and moderate risk for endocarditis, with immunodeficiencies, metabolic diseases, irradiated in the head and neck area and when an extensive or prolonged surgery is anticipated.

ReviewInterventions for smoking cessation in hospitalised patients.
An admission to hospital provides an opportunity to help people stop smoking. Individuals may be more open to help at a time of perceived vulnerability, and may find it easier to quit in an environment where smoking is restricted or prohibited. Providing smoking cessation services during hospitalisation may help more people to attempt and sustain a quit attempt. ⋯ High intensity behavioural interventions that include at least one month of follow-up contact are effective in promoting smoking cessation in hospitalised patients. The findings of the review were compatible with research in other settings showing that NRT increases quit rates.
