Review Meta AnalysisPharmacological interventions to decrease blood loss and blood transfusion requirements for liver resection.
Blood loss during liver resection is one of the most important factors affecting the peri-operative outcomes of patients undergoing liver resection. ⋯ None of the interventions seem to decrease peri-operative morbidity or offer any long-term survival benefit. Aprotinin and tranexamic acid show promise in the reduction of blood transfusion requirements in liver resection surgery. However, there is a high risk of type I (erroneously concluding that an intervention is beneficial when it is actually not beneficial) and type II errors (erroneously concluding that an intervention is not beneficial when it is actually beneficial) because of the few trials included, the small sample size in each trial, and the high risk of bias. Further randomised clinical trials with low risk of bias and random errors assessing clinically important outcomes such as peri-operative mortality are necessary to assess any pharmacological interventions aimed at decreasing blood loss and blood transfusion requirements in liver resections. Trials need to be designed to assess the effect of a combination of different interventions in liver resections.

Review Meta AnalysisAmifostine for salivary glands in high-dose radioactive iodine treated differentiated thyroid cancer.
Radioactive iodine treatment for differentiated thyroid cancer possibly results in xerostomia. Amifostine has been used to prevent the effects of irradiation to salivary glands. To date, the effects of amifostine on salivary glands in radioactive iodine treated differentiated thyroid cancer remain uncertain. ⋯ Results from two randomised controlled clinical trials suggest that the amifostine has no significant radioprotective effects on salivary glands in high-dose radioactive iodine treated differentiated thyroid cancer patients. Moreover, no health-related quality of life and other patient-oriented outcomes were evaluated in the two included trials. Randomised controlled clinical trials with low risk of bias investigating patient-oriented outcomes are needed to guide treatment choice.

Review Meta AnalysisDay hospital versus outpatient care for people with schizophrenia.
This review considers the use of day hospitals as an alternative to outpatient care. Two types of day hospital are covered by the review: 'day treatment programmes' and 'transitional' day hospitals. Day treatment programmes offer more intense treatment for people who have failed to respond to outpatient care. Transitional day hospitals offer time-limited care to people who have just been discharged from inpatient care. ⋯ Evidence is limited and dated. Day hospital care may help avoid inpatient care but data are lacking on missing on a raft of outcomes that are now considered important, such as quality of life, satisfaction, healthy days, and cost.

Review Meta AnalysisDuloxetine for treating painful neuropathy or chronic pain.
Duloxetine is a balanced serotonin and noradrenaline reuptake inhibitor licensed for the treatment of major depressive disorders, urinary stress incontinence and the management of neuropathic pain associated with diabetic peripheral neuropathy. A number of trials have been conducted to investigate the use of duloxetine in neuropathic and nociceptive painful conditions. ⋯ There is moderately strong evidence that duloxetine 60 mg and 120 mg daily are efficacious for treating pain in diabetic peripheral neuropathy and fibromyalgia but 20 mg daily is not. Minor side effects are common at therapeutic doses but serious side effects are rare. Direct comparisons of duloxetine with other antidepressants and with other drugs already shown to be efficacious in neuropathic pain would be appropriate and should include unbiased economic analyses.

Menorrhagia (heavy menstrual bleeding) is a benign yet debilitating social and health condition. Treatments prescribed in order to reduce excessive menstrual blood loss include prostaglandin synthetase inhibitors, antifibrinolytics, the oral contraceptive pill and other hormones. The combined oral contraceptive pill (OCP) is claimed to have a variety of beneficial, inducing a regular shedding of a thinner endometrium and inhibiting ovulation thus having the effect of treating menorrhagia and providing contraception. ⋯ One small study found no significant difference between groups treated with OCP, mefenamic acid, low dose danazol or naproxen. Overall, the evidence from the one study is not sufficient to adequately assess the effectiveness of OCP.This review was unable to achieve its stated objectives because of the paucity of the data.
