BACKGROUND Studies suggest that complementary and alternative medicine (CAM) is widely used in the European Union (EU). We systematically reviewed data, reporting research quality and the prevalence of CAM use by citizens in Europe; what it is used for, and why. METHODS We searched for general population surveys of CAM use by using Ovid MEDLINE (1948 to(More)
Previous studies have shown frequent allelic losses of chromosomes 9p, 10, 17p, and 22q in glial tumors. Other researchers have briefly reported that glial tumors may also show allelic losses of chromosome 19, suggesting a putative tumor suppressor gene locus on this chromo some (D. T. Ransom et al., Proc. Am. Assoc. Cancer Res., 32: 302, 1991). To evaluate(More)
UNLABELLED An increasing number of parents turn to homeopathy for treatment of their hyperactive child. Two publications, a randomised, partially blinded trial and a clinical observation study, conclude that homeopathy has positive effects in patients with attention deficit hyperactivity disorder (ADHD). The aim of this study was to obtain scientific(More)
INTRODUCTION The Health Technology Assessment report on effectiveness, cost-effectiveness and appropriateness of homeopathy was compiled on behalf of the Swiss Federal Office for Public Health (BAG) within the framework of the 'Program of Evaluation of Complementary Medicine (PEK)'. MATERIALS AND METHODS Databases accessible by Internet were(More)
BACKGROUND This study is part of a nationwide evaluation of complementary medicine in Switzerland (Programme Evaluation of Complementary Medicine PEK) and was funded by the Swiss Federal Office of Public Health. The main objective of this study is to investigate patient satisfaction and perception of side effects in homeopathy compared with conventional(More)
Expression of CD44 and of specific splice-variants of CD44 has been causally related to metastatic behaviour in a variety of carcinomas and lymphomas. To elucidate whether, in principle, similar splice-variants could be involved in glioma cell invasion we examined the expression of CD44 and its splice-variants in a series of 38 primary human brain tumors(More)
Pilocytic astrocytomas are the most common astrocytic tumors of childhood and differ clinically and histopathologically from those astrocytomas that affect adults. Studies of adult astrocytic tumors have revealed allelic losses on chromosomes 10, 17p, 19q and alterations in the epidermal growth factor receptor (EGFR) gene. We have previously examined(More)
BACKGROUND The status of complementary and alternative medicine (CAM) within the EU needs clarification. The definition and terminology of CAM is heterogeneous. The therapies, legal status, regulations and approaches used vary from country to country but there is widespread use by EU citizens. A coordination project funded by the EU has been launched to(More)
Iododeoxyuridine (IUdR) uptake and retention was imaged by positron emission tomography (PET) at 0–48 min and 24 h after administration of 28.0–64.4 MBq (0.76–1.74 mCi) of [I]IUdR in 20 patients with brain tumors, including meningiomas and gliomas. The PET images were directly compared with gadolinium contrast-enhanced or T2-weighted magnetic resonance(More)
The use of complementary and alternative Medicine (CAM) has increased over the past two decades in Europe. Nonetheless, research investigating the evidence to support its use remains limited. The CAMbrella project funded by the European Commission aimed to develop a strategic research agenda starting by systematically evaluating the state of CAM in the EU.(More)
