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 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 AnalysisBisphosphonates for osteoporosis in people with cystic fibrosis.
Osteoporosis is a bone mineralisation disorder occurring in about one third of adults with cystic fibrosis (CF). Bisphosphonates can increase bone mineral density (BMD) and decrease the risk of new fractures in post-menopausal women and people receiving long-term oral corticosteroids. ⋯ Oral and intravenous bisphosphonates increase BMD in people with CF. Severe bone pain and flu-like symptoms may occur with intravenous agents. Additional trials are needed to determine if bone pain is more common or severe (or both) with the more potent zoledronate and if corticosteroids ameliorate or prevent these adverse events. Trials in larger populations are needed to determine effects on fracture rate and survival.

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.

Review Meta AnalysisTopical capsaicin for chronic neuropathic pain in adults.
Topical creams with capsaicin are used to treat pain from a wide range of chronic conditions including neuropathic pain. Following application to the skin capsaicin causes enhanced sensitivity to noxious stimuli, followed by a period with reduced sensitivity and, after repeated applications, persistent desensitisation. There is uncertainty about the efficacy and tolerability of capsaicin for treating painful chronic neuropathies. ⋯ Capsaicin, either as repeated application of a low dose (0.075%) cream, or a single application of a high dose (8%) patch may provide a degree of pain relief to some patients with painful neuropathic conditions. Local skin irritation, which is often mild and transient but may lead to withdrawal, is common. Systemic adverse effects are rare. Estimates of benefit and harm are not robust due to limited amounts of data for different neuropathic conditions and inconsistent outcome definition.
