Vascular dementia (VD) is a syndrome or diagnosis that has different causes and clinical manifestations relating to several different vascular mechanisms and changes in the brain. Some traditional Chinese herbal medicines were developed for treating VD. DH: Yizhi capsule is one such herbal concoction which is reported to improve clinical symptoms significantly. The efficacy and adverse effects of Yizhi capsule need to be reviewed systematically and assessed critically to inform clinical practice and guide the continued search for new treatment regimens. ⋯ There is no evidence from randomised controlled trials to support or proscribe against the use of 'Yizhi capsule' as a treatment for vascular dementia.

ReviewEditorial peer review for improving the quality of reports of biomedical studies.
Scientific findings must withstand critical review if they are to be accepted as valid, and editorial peer review (critique, effort to disprove) is an essential element of the scientific process. We review the evidence of the editorial peer-review process of original research studies submitted for paper or electronic publication in biomedical journals. ⋯ At present, little empirical evidence is available to support the use of editorial peer review as a mechanism to ensure quality of biomedical research. However, the methodological problems in studying peer review are many and complex. At present, the absence of evidence on efficacy and effectiveness cannot be interpreted as evidence of their absence. A large, well-funded programme of research on the effects of editorial peer review should be urgently launched.

Fungating wounds arise from primary, secondary or recurrent malignant disease and are associated with advanced cancer. A small proportion of patients may achieve healing following surgical excision but treatment is usually palliative. Fungating wound management usually aims to slow disease progression and optimise quality of life by alleviating physical symptoms, such as copious exudate, malodour, pain and the risk of haemorrhage, through appropriate dressing and topical agent selection. ⋯ There is weak evidence from one small trial that 6% miltefosine solution applied topically to people with superficial fungating breast lesions (smaller than 1cm) who have received either previous radiotherapy, surgery, hormonal therapy or chemotherapy for their breast cancer may slow disease progression. There is insufficient evidence in this review to give a clear direction for practice with regard to improving quality of life or managing wound symptoms associated with fungating wounds. More research is needed.
