[Standards, options and recommendations: concomitant radiochemotherapy for cancer of the cervix: a critical analysis of the literature and update of SOR].
INTRODUCTION: The "Standards, Options and Recommendations" (SOR) project, started in 1993, is a collaboration between the National Federation of the French Cancer Centres (FNCLCC), the 20 French Cancer Centres (CRLCC) and specialists from French public universities, general hospitals and private clinics. The main objective is the development of clinical practice guidelines to improve the quality of health care and outcome for cancer patients. The methodology is based on literature review and critical appraisal by a multidisciplinary group of experts, with feedback from specialists in cancer care delivery. OBJECTIVES: To update, according to the methodology of SOR, the Standards, Options and Recommendations for the management of patients with cancer of the cervix, and in particular, the place of concomitant radiochemotherapy. METHODS: Data have been identified by a literature search using Medline (to April 1999) and the personal reference lists of experts. Once the guidelines were defined, the document was submitted for review to independent national and international reviewers and to the medical committees of the CRLCC. RESULTS: The principle recommendations concerning the place of radiochemotherapy in the treatment of cancer of the cervix are: 1) the available data shows a significant increase in local control (level of evidence A) and of overall survival (level of evidence B1) following concomitant radiochemotherapy as compared to radiotherapy alone or the combination of radiotherapy-hydroxyurea. For stages IB, IIA, proximal IIB with bad prognostic factors (tumour size greater than 4 cm and/or invasion of pelvic nodes and/or microscopic invasion of the parametrium) and without lumbo-aortic nodal invasion, concomitant radiochemotherapy can be considered as standard treatment. This benefit is less clear for stages distal IIB, III et IVA without para-aortic nodal invasion (level of evidence C) and must be confirmed (expert agreement); 2) the toxicity of radiochemotherapy is essentially haematologic and gastrointestinal (level of evidence B1) and is greater than that of radiotherapy alone (level of evidence B1); 3) these results have been obtained by the combination of chemotherapy based on cisplatin alone, or in combination with 5FU. Although of equal benefit, the toxicity of the cisplatin/5FU/hydroxyurea combination was greater than that of cisplatin alone in a trial comparing the two protocols. A significantly longer survival have also been obtained by the combination of chemoradiation and adjuvant chemotherapy with epirubicin (level of evidence C). These results must be confirmed; 4) the exact means of delivering the chemotherapy has not been clearly established. In fact, in these trials, some protocols use cisplatin weekly at a dose of 40 mg/m2 and others every three or four weeks at doses ranging from 50 to 75 mg/m2. Subsequent randomised studies are likely to establish optimal schema for the delivery of chemotherapy when combined with external radiotherapy and brachytherapy.

A systematic review of telemonitoring for the management of heart failure.
BACKGROUND: Telemonitoring allows a clinician to monitor, on a daily basis, physiological variables measured by patients at home. This provides a means to keep patients with heart failure under close supervision, which could reduce the rate of admission to hospital and accelerate discharge. OBJECTIVE: To review the literature on the application of telemedicine in the management of heart failure. METHODS: A literature search was conducted on studies involving telemonitoring and heart failure between 1966 and 2002 using Medline, Embase, Cochrane Library and Journal of Telemedicine and Telecare. RESULTS: Eighteen observational studies and six randomised controlled trials involving telemonitoring and heart failure were identified. Observational studies suggest that telemonitoring; used either alone or as part of a multidisciplinary care program, reduce hospital bed-days occupancy. Patient acceptance of and compliance with telemonitoring was high. Two randomised controlled trials suggest that telemonitoring of vital signs and symptoms facilitate early detection of deterioration and reduce readmission rates and length of hospital stay in patients with heart failure. One study also showed a reduction in readmission charges. One substantial randomised controlled study showed a significant reduction in mortality at 6 months by monitoring weight and symptoms in patients with heart failure; however, no difference was observed in readmission rates. Another randomised study comparing video-consultation performed as part of a home health care programme for patients with a variety of diagnoses, suggested a reduction in the costs of hospital care, which offset the cost of video-consultation. Patients with heart failure were not reported separately. One randomised study showed no difference in outcomes between the telemonitoring group and the standard care group. CONCLUSION: Telemonitoring might have an important role as part of a strategy for the delivery of effective health care for patients with heart failure. Adequately powered multicentre, randomised controlled trials are required to further evaluate the potential benefits and cost-effectiveness of this intervention.

Ursodeoxycholic acid therapy in primary biliary cirrhosis.
A review is made of the literature regarding the present status of ursodeoxycholic acid in the treatment of primary biliary cirrhosis, focusing on the difficulties encountered in establishing the efficacy of this and any other therapy in the management of the disease. It is concluded that further studies or, at least, an updated meta-analysis including the final data emerging from the multicentre, long-term, randomised, double-blind, controlled trials currently under way are needed to establish the clinical importance of ursodeoxycholic acid as a therapeutic agent in primary biliary cirrhosis.

HMG-CoA reductase inhibitors in osteoporosis: do they reduce the risk of fracture?
Osteoporosis affects a large number of people in industrialised countries. It has clinical and public-health impacts, most importantly due to subsequent fractures. Osteoporotic fractures are one of the most common causes of disability and are associated with enormous healthcare expenditure. The majority of existing treatment options for osteoporosis only inhibit bone resorption and prevent excessive bone loss but are not capable of stimulating bone formation. However, several recent in vitro and in vivo studies in animals demonstrated that HMG-CoA reductase inhibitors stimulate the production of bone morphogenetic protein (BMP-2), which is a potent regulating protein in osteoblast differentiation and activity. This suggests that HMG-CoA reductase inhibitors may have an anabolic effect on bones, making them a potentially interesting treatment option for osteoporosis. Additionally, several studies in humans showed that some HMG-CoA reductase inhibitors may have a beneficial effect on bone turnover and may lead to an increase in bone mineral density. Consequently, several observational studies tried to evaluate whether use of HMG-CoA reductase inhibitors is associated with a decreased risk of fractures. Even though not all results of these epidemiological studies, using different designs in different study populations, were entirely consistent, they provided substantial evidence that HMG-CoA reductase inhibitor use may decrease the bone fracture risk by approximately 50%. On the other hand, reanalysis of two randomised controlled trials of HMG-CoA reductase inhibitor therapy, designed to assess cardiovascular outcomes, could not show that patients treated with HMG-CoA reductase inhibitors had a lower fracture risk in comparison with placebo-treated patients. Therefore, to conclusively assess the potential of HMG-CoA reductase inhibitors in the prevention and treatment of osteoporosis, randomised controlled trials need to be performed to address this conflicting issue. Until the results of such trials are available, practitioners should prescribe the drugs that have been proven to reduce the risk of osteoporotic fractures.

Heated, humidified air for the common cold.
OBJECTIVES: To assess the effects of inhaling heated water vapour with the help of a rhinotherm (an equipment designed to deliver heated water vapour to a person's nasal cavity), in the treatment of the common cold by comparing a. symptoms b. viral shedding c. nasal resistance after a natural or experimentally induced common cold. SEARCH STRATEGY: We searched MEDLINE with MeSH headings: common cold, rhinopharyngitis, inhalation, steam, heated vapour, rhinothermy, till July 1999. EMBASE, Current Contents, review articles, cross references were also searched. Attempts were also made to contact the manufacturers for any unpublished data. SELECTION CRITERIA: Randomized trials using heated water vapour in a standardized way in patients with the common cold or volunteers with experimental induction of rhinovirus infection were included in the review. DATA COLLECTION AND ANALYSIS: All the articles retrieved were initially subjected to a review for inclusion / exclusion criteria. Review articles, editorials, abstracts with inadequate outcome description were excluded. Studies selected for inclusion were subjected to a methodological assessment. MAIN RESULTS: The results of a systematic review of six trials with 319 participants, support the use of warm vapour inhalations in the common cold in terms of relief of symptoms (Odds Ratio with 95 % CI 0.31, 0.16-0.60, Relative risk 0.56, 0.4-0. 79). Results on symptom score indices were equivocal. None of the studies demonstrated a worsening of clinical symptom scores. One study demonstrated increased nasal resistance one week after steam inhalation in contrast to an earlier study which showed improvement in the nasal resistance. There was no evidence of decreased viral shedding measured by virus isolation in the nasal secretions (Tyrrell 1989) or measurement of viral titres in nasal washings among treatment group. The rhinovirus titres in the nasal washings from the treatment group were the same as those of the placebo group on day one prior to the treatment and on all four days after the treatment. The area under curve (Hendley 1994) was also similar in the placebo and treatment groups for titres of virus in the nasal washings as were the average viral titres across five days of follow up, the maximum values after treatment, and viral shedding velocity i.e. amount of virus shed per day (Hendley 1994). Minor side effects due to thermal stress were reported in all the studies. REVIEWER'S CONCLUSIONS: Three trials demonstrated beneficial effects on the symptoms of the common cold. One study from Israel showed a decrease in nasal resistance measured by peak nasal expiratory and inspiratory flow rate. Studies done in North America failed to show any objective improvement in outcome measures with the study intervention. A multi-centre double blind randomised controlled trial testing this therapy with uniform outcome measures is recommended.

Principles of evidence based medicine.
Health care professionals are increasingly required to base clinical decisions on the best available evidence. Evidence based medicine (EBM) is a systematic approach to clinical problem solving which allows the integration of the best available research evidence with clinical expertise and patient values. This paper explains the concept of EBM and introduces the five step EBM model: formulation of answerable clinical questions; searching for evidence; critical appraisal; applicability of evidence; evaluation of performance. Subsequent articles will focus on the principles and critical appraisal of randomised controlled trials, systematic reviews, and meta-analyses, and provide a practical demonstration of the five step EBM model using a real life clinical scenario.

Effects of physical training in asthma: a systematic review.
OBJECTIVES: To assess the evidence for the effects of physical training on pulmonary function, symptoms, cardiopulmonary fitness, and quality of life in subjects with asthma. METHODS: A search was conducted for randomised controlled trials of subjects with asthma undertaking physical training using the Cochrane Airways Group register of controlled clinical trials, Medline, Embase, Sportdiscus, Science citation index, and Current contents index. Studies were included in the review if the subjects had asthma, were 8 years of age or older, and had undertaken physical training for at least 20 minutes per session, twice a week, for a minimum of four weeks. The eligibility of trials for inclusion in the review and the quality of the trials were independently assessed by two reviewers. RESULTS: Eight studies with a total of 226 subjects met the inclusion criteria for this review. Physical training had no effect on resting lung function but led to an improvement in cardiopulmonary fitness as measured by an increase in maximum oxygen uptake of 5.6 ml/kg/min (95% confidence interval 3.9 to 7.2). None of the studies measured quality of life. CONCLUSIONS: Physical training improves cardiopulmonary fitness without changing lung function. It is not clear if the improvement in fitness translates into a reduction in symptoms or an improvement in the quality of life. There is a need for further randomised controlled trials of the effects of physical training in the management of asthma.

Hormone replacement therapy in general practice: a survey of doctors in the MRC's general practice research framework.
OBJECTIVES: To survey current prescribing practice for hormone replacement therapy among general practitioners and to elicit their views on the role of hormone replacement therapy in the prevention of osteoporosis and cardiovascular disease; to determine whether they would participate in randomised controlled trials to evaluate the long term beneficial and adverse effects of hormone replacement therapy. DESIGN: Postal questionnaires to general practitioners throughout the United Kingdom. PARTICIPANTS: 1268 general practitioners in the Medical Research Council's general practice research framework. RESULTS: 1081 (85%) doctors in 220 (95%) practices responded. The doctors were currently prescribing hormone replacement therapy to an estimated 9% of their female patients aged 40 to 64, and 55% of doctors were prescribing opposed hormone replacement therapy (oestrogen plus progestogen) to more patients than a year previously. Over half the doctors would consider prescribing hormone replacement therapy for prevention of osteoporosis (670, 62%) and cardiovascular disease (611, 57%) to asymptomatic women. Overall, 79% of the doctors (851) would definitely or probably consider entering women who have had a hysterectomy into a randomised controlled trial comparing unopposed (oestrogen only) hormone replacement therapy with opposed hormone replacement therapy; 49% (524) would enter patients with a uterus into such a trial. Among a subsample, 85% (180/210) would consider entering patients without menopausal symptoms into a trial comparing hormone replacement therapy with no treatment (unopposed in patients who have had a hysterectomy, opposed in those with a uterus). CONCLUSION: There is considerable uncertainty among general practitioners as to the balance of beneficial and harmful effects of hormone replacement therapy in the long term, particularly relating to its use for prevention of osteoporosis and cardiovascular disease. Most of these doctors would be prepared to participate in randomised controlled trials to determine the long term effects of this increasingly widely used treatment.

Will we ever know when to treat HIV infection?
Confidence in the efficacy of using antiretroviral drugs to treat HIV infection has grown in the past year as a result of the prolonged survival of those randomly allocated to receive an additional drug in comparative controlled trials. HIV remains, however, the only serious infectious disease for which antimicrobial treatment is deliberately delayed. This is because infected subjects can often be symptomless for more than a decade in the absence of any treatment, and results from trials with the nucleoside analogue reverse transcriptase inhibitor zidovudine have failed to show any evidence for extended survival in those beginning treatment early compared with those who deferred treatment. The new confidence in currently available treatments, and in the prospects for new ones, inevitably leads to renewed questioning of the current strategy of waiting for signs of immune deficiency before electing to intervene. A new randomised controlled trial comparing strategies of early and deferred treatment is required to assess whether the time has come for intervention immediately after HIV has been diagnosed.

Routine protein energy supplementation in adults: systematic review.
OBJECTIVES: To determine whether routine oral and enteral nutritional supplementation can improve the weight, anthropometry, and survival of adult patients. DESIGN: Systematic review of randomised controlled trials of oral or enteral protein supplementation in adults. Trials were identified from Medline (Silver Platter 3.11, 1966-96), reference lists of identified studies and review articles, and communication with feed manufacturers. SUBJECTS: Randomised controlled trials comparing oral or enteral protein supplementation with no routine supplementation. All trials of adult subjects were included except those addressing nutrition in pregnancy. MAIN OUTCOME MEASURES: Change in body weight and anthropometry (mid-arm muscle circumference), and all cause case fatality recorded at the end of scheduled follow up. Body weight and anthropometry were analysed as the weighted mean difference and 95% confidence intervals of the percentage change in these variables. Case fatality was analysed with odds ratio and 95% confidence intervals. RESULTS: 32 eligible reports (2286 randomised patients) published between February 1979 and July 1996 were identified, of which 30 (93.8%) (2062 randomised patients) reported outcomes of interest. Case fatality data were available for 1670 (81%) patients, and continuous variable data for up to 1607 (78%) patients. The treatment group receiving routine nutritional supplementation showed consistently improved changes in body weight and anthropometry compared with controls; weighted mean difference 2.06% (95% confidence interval 1.63% to 2.49%) and 3.16% (2.43% to 3.89%) respectively. The pooled odds ratio for death in the treatment group was 0.66 (0.48 to 0.91, 2P<0.01). Apparent benefits were observed in several prespecified subgroups of patients, treatment settings, and interventions, but were not evident if trials with less robust methodology were excluded. CONCLUSIONS: Routine oral or enteral supplementation seems to improve the nutritional indices of adult patients, but there are insufficient data in trials which meet strict methodological criteria to be certain if mortality is reduced. Benefits were not restricted to particular patient groups. Further large pragmatic randomised controlled trials of routine nutritional supplementation are justified.

The safety and efficacy of the administration of recombinant activated factor VII in major surgery and trauma patients.
Recombinant activated Factor VII (rFVIIa) has been successfully used in the treatment of haemophilia A and B with associated inhibitors for some years. Activated Factor VII binds to activated platelets independently of tissue factor. The resulting stimulation of an exaggerated early thrombin burst at sites of vascular injury makes it an attractive potential treatment for massive, uncontrolled bleeding associated with surgery and trauma. This article describes the evidence relating to surgery and trauma. The lack of large, controlled trials of rFVIIa means that a definitive recommendation regarding its use cannot be made at present. However, in the context of clearly defined protocols and balanced treatment strategies, rFVIIa may have a role in traumatic bleeding. Large scale, randomised controlled trials in trauma are required, as is further work on the safety profile of rFVIIa with an independent international safety monitoring committee.

Anti-tumour necrosis factor therapy for ulcerative colitis: evidence to date.
Infliximab, the chimeric monoclonal antibody directed against tumour necrosis factor (TNF)-alpha, has profoundly changed therapy for Crohn's disease (CD). However, for ulcerative colitis (UC), before the publication of ACT 1 and ACT 2 (Active Ulcerative Colitis Trials 1 and 2), there were only a few open-label and controlled trials that evaluated the role of infliximab in the treatment of UC. Results from these earlier studies were equivocal and ambiguous. However, the ACT 1 and ACT 2 trials were large, randomised and placebo-controlled, and have shown that infliximab is significantly more efficacious than placebo in treating both corticosteroid-responsive and -refractory moderate to severe UC. Data from these two studies showed that in patients with moderate to severe UC, treatment with infliximab (5 and 10 mg/kg), compared with placebo, led to significantly higher rates of clinical response, clinical remission and mucosal healing. However, a significant proportion of patients who were receiving oral corticosteroids at the start of the trials, remained on corticosteroids despite infliximab therapy. Additionally, the safety profile of the drug was found to be similar to what has been reported in clinical studies of infliximab in patients with CD. On the basis of currently available data, we use infliximab as a remission-inducing agent in patients who have moderate to severe UC and are either refractory to or intolerant of mesalazine (5-ASA) products and immunomodulators. Moreover, infliximab seems to be a reasonable therapeutic modality for remission maintenance in those patients with UC in whom mesalazine products and immunomodulators have failed. Although data are limited, infliximab may be considered as a remission-inducing agent in patients with moderate to severe UC which is refractory to oral corticosteroids. However, the role of infliximab in the treatment of UC patients who are dependent on oral corticosteroids is still unclear and, therefore, should be considered only in patients who cannot be successfully transitioned to or are intolerant of oral immunomodulators. Furthermore, infliximab may be an alternative to ciclosporin (cyclosporin) in hospitalised patients with severe to moderately severe but not fulminant UC who do not respond to intravenous corticosteroids. At present, there is insufficient evidence to advocate using infliximab as a first-line agent for UC patients with mild or moderate to severe disease. Future randomised, controlled trials with clearly defined patient populations should further help to clarify the definitive role of infliximab in the therapeutic scheme for UC.

[What is the evidence with regard to the effectiveness of orlistat?].
BACKGROUND: Obesity is worldwide one of today's most important medical and public health problems. Orlistat (Xenical) is a relatively new drug in the pharmacological treatment of obesity which partially blocks fat absorption. The following article analyses the available evidence of orlistat's effectiveness in the treatment of obese patients. METHODS: Three randomised controlled trials investigating the effect of orlistat in the treatment of obesity were identified by systematic Medline search. The internal and external validity of these studies was assessed using systematic criteria. RESULTS: All three studies consistently demonstrate a treatment benefit of orlistat compared to placebo. Patients treated with orlistat lost an average of 3.4 kg more than patients taking placebo while on a hypocaloric diet. Simultaneously, control of cardiovascular risk factors improved independently of the observed weight loss. Up to 40% of all patients experienced gastrointestinal side effects which were generally well tolerated. The studies prove that treatment with orlistat can result in a moderate weight reduction. However, the results of the studies cannot be easily generalised to obese patients in a primary care setting, due to limitations concerning the studies' internal and external validity. CONCLUSIONS: Based on these studies orlistat is an efficient pharmacological treatment for obesity in patients adhering to a hypocaloric diet. Studies demonstrating orlistat's effectiveness in a primary care setting are so far lacking. From a public health perspective there is a need for a randomised controlled trial showing not only orlistat's effectiveness on surrogate markers in a primary care setting but, ideally, a reduction in obesity-related mortality and morbidity.

[Interactions between radiation and hormonal therapy in breast cancer: simultaneous or sequential treatment].
BACKGROUND: Combining radiation and hormone therapy (administration of selective estrogen receptor modulators) has become common clinical practice in recent years for receptor positive breast cancer. Little is known about a possible interaction of both treatment modalities if they are given simultaneously. Tamoxifen (antiestrogen molecule, triphenylethylene derivative) may theoretically render cancer cells less responsive to radiotherapy arresting hormone-receptor-positive cells in G0/G1 phase and increase the risk of breast and lung fibrosis stimulating the secretion of transforming growth factor beta in human fibroblasts. PURPOSE: This article reviews the published data to assess the impact of sequencing of hormonal and radiation therapy on outcomes in breast cancer. METHODS: Computerised searches for publications debating the sequencing of hormonal therapy relative to radiation therapy were done using MEDLINE data. RESULTS: Results of tamoxifen experiments with cell culture regarding radioprotection of tumour clonogens are conflicting. In contrast to in vitro results, in animal studies no protective effect of tamoxifen was observed. In one in vitro study, letrozole (non-steroid selective aromatase inhibitor) had a radiosensitizing effect on breast-cancer lines. No randomised clinical trials to date have studied sequencing of tamoxifen or other selective estrogen receptor modulators and radiotherapy. Results from retrospective clinical studies which included treatment arms with and without tamoxifen showed reduction in tumour recurrence with tamoxifen. Some of these studies have noted increased risk of lung and breast fibrosis with tamoxifen with radiotherapy. Results of three articles examined the effect of tamoxifen sequence showed no adverse effect on local control or survival in sequential versus concurrent tamoxifen and radiation patients. One of the three studies also assessed the risk of complications with respect to the timing of tamoxifen with radiotherapy. There was no difference in the rates of complications between the two groups. The association of radiation and selective aromatase inhibitors or aromatase inactivators has not been addressed in clinical studies. CONCLUSIONS: Combined application of tamoxifen and radiotherapy improves survival and local control in breast cancer. Available clinical studies do not indicate that the simultaneous application of tamoxifen and radiotherapy is disadvantageous, as was suggested by some of the in vitro studies. The risk of subcutaneous breast and lung fibrosis might be slightly increased if tamoxifen is given simultaneously with radiotherapy. Both treatment modalities should be started early after surgery. There is no sufficient evidence to withhold tamoxifen administration during irradiation of breast cancer. The issue of optimal sequencing of hormonal and radiotherapy should be addressed in randomised clinical trials.

[Chemoradiotherapy and anal canal cancer].
Local control and sphincter preservation are the two challenges of anal canal cancer treatment. These tumors are radio- and chemo-sensitive and treatment moved from surgical approach, with abdominoperineal resection, to definitive radiation therapy with or without concurrent chemotherapy. Randomised trials proved the benefit of combined modality with chemoradiotherapy and of mitomycine C (MMC) compared with radiotherapy alone, with a toxic death rate of about 2%. Indications of chemoradiotherapy are locally advanced tumor T2 > or = 4 cm, T3-4 or N1-3 but the best modalities of combined treatment are still under debate. Standard chemotherapy is 5 flurouracile (5FU) + MMC, but cisplatinum (CDDP) is an effective and well tolerated substitute for MMC. Favourable results with CDDP-containing regimen in term of toxicity and carcinologic control have been reported in phase II and retrospective studies. Total radiation dose, overall duration of radiation therapy, duration of the gap and indications of additional boost are not clear, but it is demonstrated that overall duration of treatment should be as short as possible to improve the therapeutic radio. Phase II and III studies are ongoing, to evaluate the best chemotherapy regimen between 5FU+MMC and 5FU+CDDP, the benefit of neoadjuvant or maintenance chemotherapy and the interest of increased total dose. Next future could be the utilisation of oral 5FU. This article is a review of past randomised trials, phases II and retrospective study on radiochemotherapy of anal canal carcinoma.

[Calcaneal fractures--the most frequent tarsal fractures].
Operative treatment of intra-articular calcaneal fractures with anatomical reduction and early mobilisation has lead to a considerable improvement of the functional results of these severe injuries over the recent two decades. New tendencies like modified approaches tailored according to the vascular anatomy, arthroscopic control of joint reduction in conjunction with open or percutaneous procedures, early flap coverage for severe open fractures or closed fractures with full thickness skin necrosis, the use of interlocking plates that further minimises the need of bone grafting and subtalar arthrolysis at the time of hardware removal for fibrous overgrowth have the potential for further improvement of the outcome. The observation from several comparative studies that operative treatment leads to superior results in displaced intra-articular calcaneal fractures has been qualified in a recent prospective, randomised multicentre trial. This paper presents and the authors' experience with the demanding operative treatment of these fractures together with new developments aiming at improving the clinical results.
