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.

Olanzapine is an atypical antipsychotic that is reported to be effective without producing the disabling extrapyramidal side effects associated with the older, typical antipsychotic drugs. ⋯ The large proportions of participants leaving the studies early, in the large multi-centre trials makes it difficult to draw firm conclusions on clinical effects. For people with schizophrenia olanzapine may offer antipsychotic efficacy with fewer extrapyramidal side effects than typical drugs but more weight gain. Large, long-term randomised trials with participants, interventions and primary outcomes that are familiar to those wishing to help those with schizophrenia are long overdue.

ReviewAntimicrobial drugs for treating methicillin-resistant Staphylococcus aureus colonization.
Eradication strategies for methicillin-resistant Staphylococcus aureus (MRSA) are variable. We sought to summarize the evidence for use of antimicrobial agents to eradicate MRSA. ⋯ There is insufficient evidence to support use of topical or systemic antimicrobial therapy for eradicating nasal or extra-nasal MRSA. There is no demonstrated superiority of either topical or systemic therapy, or of combinations of these agents. Potentially serious adverse events and development of antimicrobial resistance can result from therapy.

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.

ReviewTreatments for gestational diabetes and impaired glucose tolerance in pregnancy.
Gestational diabetes and impaired glucose tolerance (IGT) in pregnancy affects between 3 and 6% of all pregnancies and both have been associated with pregnancy complications. A lack of conclusive evidence has led clinicians to equate the risk of adverse perinatal outcome with pre-existing diabetes. Consequently, women are often intensively managed with increased obstetric monitoring, dietary regulation, and in some cases insulin therapy. However, there has been no sound evidence base to support intensive treatment. The key issue for clinicians and consumers is whether treatment of gestational diabetes and IGT will improve perinatal outcome. ⋯ There are insufficient data for any reliable conclusions about the effects of treatments for impaired glucose tolerance on perinatal outcome.
