The prevention and management of acute skin reactions related to radiation therapy: a systematic review and practice guideline.

GOALS OF WORK: To develop a practice guideline report on the questions: What are the optimal methods to prevent acute skin reactions (occurring within the first 6 months of irradiation) related to radiation therapy? What are the optimal methods to manage acute skin reactions related to radiation therapy? MATERIALS AND METHODS: Cancer Care Ontario's Supportive Care Guidelines Group (SCGG) conducted a systematic review of literature on this topic. Evidence-based recommendations were formulated to guide clinical decision making, and a formal external review process was conducted to validate the relevance of these opinions for Ontario practitioners. MAIN RESULTS: Twenty-eight trials meeting the inclusion criteria were identified. Of the twenty-three trials that evaluated preventative methods, washing was the only practice which significantly prevented skin reaction. Some evidence suggested topical steroid creams and calendula ointment might be effective. None of the five trials evaluating skin reaction management detected a positive effect using steroid cream, sucralfate cream, or dressings. CONCLUSIONS: Skin washing, including gentle washing with water alone with or without mild soap, should be permitted in patients receiving radiation therapy to prevent acute skin reaction. There is insufficient evidence to support or refute specific topical or oral agents for the prevention or management of acute skin reaction. In the expert opinion from the SCGG, the use of a plain, non-scented, lanolin-free hydrophilic cream may be helpful in preventing radiation skin reactions. In addition, a low dose (i.e., 1%) corticosteroid cream may be beneficial in the reduction of itching and irritation.

Weighing the evidence to formulate dietary guidelines.

Dietary guidelines have broad implications for the health of individuals and populations. Increasingly, government agencies and medical organization that issue guidelines have pursued evidence-based approaches. These approaches emphasize a comprehensive, critical, and explicit examination of the scientific evidence that the proposed dietary practice will improve health. Evidence-based guidelines typically feature an explicit methodology, include as their foundation a systematic review of the evidence, provide graded recommendations that are linked directly to the supporting evidence, and state explicitly when recommendations are based on opinion. Guideline development usually involves some combination of six steps: (1) specification of the topic and the guideline development methodology, (2) systematic review of the evidence, (3) consideration of expert opinion, (4) public policy analysis, (5) drafting of the document, and (6) peer review. The supporting evidence undergoes critical appraisal, including an assessment of the magnitude of the effect on outcomes observed in studies, the quality of the studies reporting the effect, or both. Dietary guidelines should also consider untoward effects, potential harms, and economic implications to society, the food industry, and others. A hallmark of evidence-based guidelines is making explicit the strength of recommendations and the quality of the evidence on which they are based. Grading systems are commonly used to rate the quality of the supporting evidence.

Early use of inhaled corticosteroids in the emergency department treatment of acute asthma.

BACKGROUND: Systemic corticosteroids therapy is central to the management of acute asthma The use of inhaled steroids may also be beneficial in this setting. OBJECTIVES: To determine the benefit of ICS for the treatment of patients with acute asthma managed in the emergency department (ED). SEARCH STRATEGY: Randomised controlled trials (RCTs) were identified from the Cochrane Airways Review Group register. Bibliographies from included studies, known reviews, and texts also were searched. SELECTION CRITERIA: Only RCTs or quasi-randomised trials were eligible for inclusion. Studies were included if patients presented with acute asthma to the ED or its equivalent, and were treated with ICS or placebo, in addition to standard therapy. Two reviewers independently selected potentially relevant articles, and then independently selected articles for inclusion. Methodological quality was independently assessed by two reviewers. DATA COLLECTION AND ANALYSIS: Data were extracted independently by two reviewers if the authors were unable to verify the validity of extracted information. Missing data were obtained from the authors or calculated from other data presented in the paper. MAIN RESULTS: Seven trials were selected for inclusion, but data were not available for one of them. In the six usable rials, (4 adult, 2 paediatric), a total of 352 patients were studied (179 ICS, 173 non-ICS treated). Patients treated with ICS were less likely to be admitted to hospital (OR: 0.30; 95% CI: 0.16, 0.57). This benefit was confined to patients not receiving concomitant systemic steroids. Such patients showed the same, but non-significant, trend towards reduced admissions compared to placebo treatment (OR 0.46; 95% CI: 0. 19, 1.11). In children, ICS appeared to be at least as effective as systemic steroids (OR 0.5; 95% CI: 0.24, 1.06). Patients receiving ICS demonstrated small, significant improvements in peak expiratory flows (PEFR WMD: 7%; 95% CI: 3, 13) and forced expiratory volumes (FEV-FEV1 WMD: 5.0%; 95% CI: 0.4, 9.7). The treatment was well tolerated, with few reported adverse side effects. REVIEWER'S CONCLUSIONS: Inhaled steroids reduced admission rates in patients with acute asthma who were not receiving concomitant systemic steroids. In children, inhaled steroids appear to be at least as effective as systemic steroids. Further research is needed to clarify the effect of ICS when used in addition to systemic corticosteroids, and to determine the optimal dose, agent, and frequency of ICS administration.

Communicating with children and adolescents about their cancer.

BACKGROUND: Communication with children and adolescents with cancer about their disease and treatment and the implications of these is an important aspect of good quality care. It is often poorly performed in practice. Various interventions have been developed that aim to enhance communication involving children or adolescents with cancer. OBJECTIVES: To examine the effects of interventions to enhance communication with children and/or adolescents about their cancer, its treatment and their implications. SEARCH STRATEGY: The following electronic databases were searched: Cochrane Library; Medline; PsycLit; Cinahl; Cancerlit; EMBASE; Sociofile; Health Management Information Consortium; ASSIA; LISA; ERIC; PAIS; Information Science Abstracts; Dissertation Abstracts; JICST; Pascal; Linguistics and Language Behavior Abstracts; Mental Health Abstracts; AMED; MANTIS. Bibliographies of identified studies were also checked and contact made with experts in the field. SELECTION CRITERIA: Randomised and non-randomised controlled trials and before and after studies that evaluated the effects of interventions to enhance communication with children and/or adolescents about their cancer, treatment and related issues. DATA COLLECTION AND ANALYSIS: Data relating to the interventions, populations and outcomes studied and the design and methodological quality of included studies were extracted by one reviewer and checked by another reviewer. A narrative summary of the results is presented. MAIN RESULTS: Six studies met the criteria for inclusion. They were diverse in terms of the interventions evaluated, study designs used, types of people who participated and the outcomes measured. One study of a computer-assisted education programme reported improvements in knowledge and understanding about blood counts and cancer symptoms. Two out of two studies of school reintegration programs reported improvements in some aspects of psychosocial wellbeing (one in anxiety and one in depression), social wellbeing (two in social competence and one in social support) and behavioural problems; and one reported improvements in physical competence. REVIEWER'S CONCLUSIONS: Interventions to enhance communication involving children and adolescents with cancer have not been widely or rigorously assessed. The weak evidence that exists suggests that some children and adolescents with cancer may derive some benefit from specific information-giving programs and from interventions that aim to facilitate their reintegration into school and social activities. More research is needed to investigate the effects of these and other related interventions.

Antithrombotic drugs for carotid artery dissection.

BACKGROUND: Extracranial internal carotid artery dissection can lead to occlusion of the artery and hence cause an ischemic stroke. It is the underlying stroke mechanism in approximately 2.5% of all strokes, and the second leading cause of stroke in patients younger than 45 years of age. Antithrombotic agents (heparin, oral anticoagulants or antiplatelet drugs) may prevent arterial thrombosis in eICAD, but these benefits may be offset by increased bleeding. OBJECTIVES: To determine whether antithrombotic drugs (antiplatelet drugs, anticoagulation) are effective and safe in treatment of patients with extracranial internal carotid artery dissection, and which is the better treatment. SEARCH STRATEGY: We searched the Cochrane Stroke Group specialised Trials Register for relevant randomised trials and controlled clinical trials. In addition, we performed comprehensive searches of MEDLINE and EMBASE and checked reference lists of all relevant papers for additional eligible studies. SELECTION CRITERIA: Randomised controlled trials, controlled clinical trials assessing the efficacy of antiplatelet drugs or anticoagulants in the treatment of extracranial carotid artery dissection. For non-randomised trials, case series (studies), that reported on antithrombotic treatment with at least 4 patients, were eligible. All trials and studies were assessed for eligibility. Data from all eligible studies were extracted independently by two reviewers. Disagreements were resolved by discussion. DATA COLLECTION AND ANALYSIS: Data on the primary outcome measures were extracted systematically. These were: all deaths, vascular deaths, and disability. Secondary outcomes were: first stroke occurrence, stroke recurrence, any stroke during reported follow-up, extracranial haemorrhage, and intracranial haemorrhage. The first choice treatment was taken for analyses. MAIN RESULTS: No randomised trials and 49 case series (including 683 treated patients) were identified. No reliable comparisons of antiplatelet drugs or anticoagulants with control were available. 24 eligible studies including 286 patients (who either received antiplatelet drugs or anticoagulants) were included in the analysis. There was no significant difference in odds of death comparing antiplatelet drugs with anticoagulants, odds ratio (OR) 2.41, 95% CI 0.27-21.80). There was also no significant difference in the odds of being alive but disabled (OR 1.65, 95% CI 0.50-5.42). Few major haemorrhages were reported. REVIEWER'S CONCLUSIONS: There were no randomised trials comparing either anticoagulants or antiplatelet drugs with control. There is, therefore, no evidence to support their routine use for the treatment of extracranial internal carotid artery dissection. There were also no randomised trials, that directly compared anticoagulants with antiplatelet drugs, and the reported non-randomised studies did not show any evidence of a significant difference between the two. We suggest that a randomised trial including at least 1000 patients in each treatment arm with this condition is clearly needed.

Hospitalisation and bed rest for multiple pregnancy.

BACKGROUND: Bed rest used to be widely advised for women with a multiple pregnancy. OBJECTIVES: The objective was to assess the effect of bed rest in hospital for women with a multiple pregnancy for prevention of preterm birth and other fetal, neonatal and maternal outcomes. SEARCH STRATEGY: The Cochrane Pregnancy and Childbirth Group trials register, the Cochrane Controlled Trials Register and reference lists of relevant articles were searched. Date of last search: January 1999. SELECTION CRITERIA: Randomised trials which compare outcomes in women with a multiple pregnancy and their babies who were offered bed rest in hospital with women only admitted to hospital if complications occurred. DATA COLLECTION AND ANALYSIS: Assessment for inclusion and methodological quality of the trials was done by the reviewer. Data were extracted by the reviewer and double entered. All eligible trials were included in the initial analysis. Prespecified sensitivity analyses have been carried out to evaluate the effect of trial quality, the effects of hospitalisation for bed rest in women with an uncomplicated twin pregnancy, in women with a triplet pregnancy and in women with a twin pregnancy complicated by cervical effacement and dilatation prior to labour. MAIN RESULTS: Six trials were included which involved over 600 women and 1400 babies. (1) Analyses of all trials. Routine bed rest in hospital for multiple pregnancy did not reduce the risk of preterm birth, or perinatal mortality. There was a trend to a decreased number of low birth weight infants born to women in the routinely hospitalised group, which became significant when the trial using alternate allocation was excluded (odds ratio (OR) 0.79; 95% confidence interval (CI) 0.63-0.99). No differences were seen in the number of very low birth weight infants. No support for the policy was found in other neonatal outcomes. No information is available on developmental outcomes for infants in any of the trials. Women's views about the care they received were reported rarely. (2) Analyses of hospitalisation for bed rest in women with an uncomplicated twin pregnancy. The risk of preterm birth was not reduced. Indeed significantly more women delivered very preterm (<34 weeks gestation) (OR 1.84; 95% CI 1.01-3.34). No differences were seen in perinatal mortality, or in other neonatal outcomes. Women receiving hospitalisation for bed rest had a decreased risk of developing hypertension (OR 0.55; 95% CI 0.32-0.97), although this effect was no longer apparent when the trial using alternate allocation was excluded. (3) Analyses of hospitalisation for bed rest in women with a triplet pregnancy. Most of the comparisons made between the hospitalised and control groups suggest beneficial treatment effects from routine hospitalisation for bed rest. However all the differences observed between the experimental and control groups were compatible with chance variation. (4) Analyses of hospitalisation for bed rest in women with a twin pregnancy complicated by cervical effacement and dilatation prior to labour. No differences were seen in the risk of preterm birth, perinatal mortality, fetal growth or in other neonatal outcomes. REVIEWER'S CONCLUSIONS: There is currently not enough evidence to support a policy of routine hospitalisation for bed rest in multiple pregnancy. No reduction in the risk of preterm birth or perinatal death is evident, although there is a suggestion that fetal growth is improved. For women with an uncomplicated twin pregnancy the results of this review suggest that it may be harmful in that the risk of very preterm birth is increased. Until further evidence is available to the contrary, the policy cannot be recommended for routine clinical practice.

Fetal electrocardiogram plus heart rate recording for fetal monitoring during labour.

BACKGROUND: It is thought that adding fetal electrocardiography (ECG) to cardiotocography (CTG) alone may provide better information about fetal heart activity. OBJECTIVES: The objective of this review was to assess the effects of simultaneous recording of fetal electrocardiographic waveforms plus conventional cardiotocography, with cardiotocography alone, during labour. SEARCH STRATEGY: We searched the Cochrane Pregnancy and Childbirth Group trials register. SELECTION CRITERIA: Randomised trials of electrocardiogram waveform analysis with or without cardiotocography during labour. DATA COLLECTION AND ANALYSIS: Trial quality was independently assessed by two reviewers. Data extraction was done by one reviewer and checked by the second reviewer. Study authors were contacted for additional information. MAIN RESULTS: One study of 2434 pregnant women was included. This trial was of sound methodological quality. The number of operative deliveries for fetal distress was reduced by half in the electrocardiographic waveform and cardiotocography group (odds ratio 0.53, 95% confidence interval 0.39 to 0.73). There was no apparent effect on the rate of operative delivery for poor progress of labour (odds ratio 1.05, 95% confidence interval 0.87 to 1.27). The use of the electrocardiographic waveform analysis monitor had no obvious effect on the condition of the newborn. REVIEWER'S CONCLUSIONS: Analysis of the fetal electrocardiographic waveform during labour may be associated with reduced obstetric intervention without jeopardising fetal outcome.

Nutritional supplementation for hip fracture aftercare in the elderly.

BACKGROUND: Fractures of the hip are an important cause of later ill health and mortality in elderly people. People with hip fractures are often malnourished at the time of fracture, and have poor food intake in hospital. OBJECTIVES: This review assesses the effects of nutritional interventions in elderly people recovering from hip fracture. SEARCH STRATEGY: We searched the Cochrane Musculoskeletal Injuries Group trials register, the Cochrane Controlled Trials Register, Medline, Nutrition Abstracts and Reviews, Embase, Biosis, Cinahl, Healthstar and reference lists. We contacted investigators, and hand searched Proceedings of the Nutrition Society, Clinical Nutrition and The Journal of Parenteral and Enteral Nutrition. Date of the most recent search: June 1999. SELECTION CRITERIA: Randomised and quasi-randomised trials of nutritional interventions of mainly older patients (aged over 65 years) with hip fracture. DATA COLLECTION AND ANALYSIS: Trial allocation to included, excluded and awaiting assessment categories, was by consensus. Both reviewers independently extracted data and assessed trial quality. Additional information was sought from all trialists. Pooling of data for primary outcomes and select exploratory analyses were undertaken. MAIN RESULTS: Fifteen randomised trials involving 943 participants were included. Overall the quality of trials was poor; specifically in terms of allocation concealment, assessor blinding and intention to treat analysis. This, and the limited availability of outcome data, mean that the following results must be interpreted with caution. Oral multinutrient feeds (providing non-protein energy, protein, some vitamins and minerals), evaluated by six trials, may reduce unfavourable outcome (death or complications) (14/66 versus 26/73; Peto odds ratio 0.28, 95% confidence interval 0.11 to 0.67), but did not demonstrate an effect on mortality (12/91 versus 14/97; Peto odds ratio 0.82, 95% confidence interval 0.34 to 1.96). Four trials, examining nasogastric multinutrient feeding, showed no evidence for an effect on mortality (Peto odds ratio 0.98, 95% confidence interval 0.44 to 2.17), but the studies were heterogeneous regarding case-mix. Insufficient information was provided to evaluate unfavourable outcome. The effect of protein in an oral feed, tested in two trials, showed no evidence for an effect on mortality (Peto odds ratio 0.93, 95% confidence interval 0.31 to 2.79), but may have reduced days spent in rehabilitation wards. Two trials, testing intravenous thiamin (vitamin B1) and other water soluble vitamins, or 1-alpha-hydroxycholecalciferol (an active form of vitamin D) respectively, produced no evidence of benefit for either vitamin supplement. REVIEWER'S CONCLUSIONS: The strongest evidence for the effectiveness of nutritional supplementation exists for oral protein and energy feeds, but the evidence is still very weak. Future trials are required which overcome the defects of the reviewed studies, particularly inadequate size, methodology and outcome assessment.

International collaboration in conducting systematic reviews: the Cochrane Collaborative Review Group on HIV Infection and AIDS.

To make sound health care decisions, policy makers, providers and researchers need access to relevant research findings. The role of systematic reviews is increasingly acknowledged as an important contribution in evidence-based health care decision making, and several review efforts, including that of the international Cochrane Collaboration, are under way. The Cochrane Collaborative Review Group on HIV Infection and AIDS (CRG on HIV/AIDS), conducts systematic reviews on the prevention and the treatment of HIV infection and AIDS and is guided by the Cochrane Collaboration's principles, which include minimizing potential bias, ensuring quality in the review process, keeping reviews up to date, and enhancing collaboration. The CDC HIV/AIDS Prevention Research Synthesis (PRS) project is working closely with the CRG on HIV/AIDS to produce Cochrane reviews of behavioral prevention interventions and on development and maintenance of a centralized, cumulative electronic database of HIV/AIDS behavioral prevention studies. Systematic reviews can play an important role in advancing evidence-based policy and practice in HIV/AIDS prevention and care.

Immediate post-abortal insertion of intrauterine devices.

OBJECTIVES: To assess the safety and efficacy of IUD insertion immediately after spontaneous or induced abortion. SEARCH STRATEGY: We used Medline, Popline, and EMBASE computer searches, supplemented by review articles and contacts with investigators. SELECTION CRITERIA: We sought all randomized controlled trials that had at least one treatment arm that involved IUD insertion immediately after an induced abortion or after curettage for spontaneous abortion. We identified 12 trials which described random assignment but excluded three from this review. Two of these revealed unethical research conduct, and one used alternate assignment to treatments. DATA COLLECTION AND ANALYSIS: We evaluated the methodological quality of each report and abstracted information onto a data collection form. We focused on gross discontinuation rates (single-decrement life table analysis) for accidental pregnancy, perforation, expulsion, and pelvic inflammatory disease. We entered the data into RevMan 3.1 for analysis of Peto odds ratios. MAIN RESULTS: In large multicenter trials, the TCu 220C device proved superior to either the Lippes Loop D or the Copper 7 IUDs for immediate post-abortal insertion. The Peto OR for discontinuation for pregnancy was 0.4 (95% CI 0.2-0.7) compared with the Lippes Loop D and 0.5 (95% CI 0.3-0.8) compared with the Copper 7. Expulsions were also significantly less common with the TCu 220C than with the other two IUDs. In single-center trials, the Nova T IUD had a signicantly higher discontinuation rate for pregnancy than did the Multiload 250 (OR 4.5; 95% CI 1.0-19.8), while the Nova T had a significantly lower discontinuation rate for pregnancy than did the TCu 200 (OR 0.3; 95% CI 0.1-0.9). Only one trial compared immediate vs. delayed insertion. In this trial, the performance of the Copper 7 IUD inserted immediately after abortion was inferior to that after interval insertion (remote from pregnancy), although the differences were not statistically significant. Addition of copper sleeves to a Lippes Loop D improved its performance, but addition of a topical hydrogel to a Spring Coil did not offer benefit. Overall, rates of perforation and pelvic inflammatory disease were low. REVIEWER'S CONCLUSIONS: Insertion of an IUD immediately after abortion is both safe and practical. This was true for both induced and reported "spontaneous" abortions, many of which may have been induced under clandestine circumstances. IUD expulsion rates were higher after second-trimester abortions than after earlier abortions, so delaying insertion may be advisable after later abortions. Although Copper 7 devices inserted unrelated to pregnancy may perform better than those inserted after abortion, many women who express interest in intrauterine contraception do not return for the scheduled insertion. These women may remain unprotected against unintended pregnancy. However, evidence is inadequate to compare the safety and efficacy of IUD insertion immediately after abortion vs. insertion some weeks later.

Techniques for preventing hypotension during spinal anaesthesia for caesarean section.

BACKGROUND: Maternal hypotension is the most frequent complication of a spinal anaesthetic for caesarean section with an incidence approaching 100%. Most workers define hypotension as a maternal systolic blood pressure below 70-80% of baseline recordings and/or an absolute value of < 90 -100mmHg. The frequent occurrence and rapid onset of hypotension during spinal anaesthesia has encouraged anaesthetists to try and prevent or minimise the associated maternal symptoms of nausea and vomiting during the establishment of the block. Untreated, severe hypotension can also pose serious risks to both mother (unconsciousness, pulmonary aspiration, apnoea or even cardiac arrest) and baby (impaired placental perfusion leading to hypoxia, fetal acidosis and neurological injury). A range of strategies is currently used to prevent or minimise hypotension but there is no established ideal technique. OBJECTIVES: To assess the relative efficacy and side effects of prophylactic interventions for hypotension following spinal anaesthesia for caesarean section. SEARCH STRATEGY: The Cochrane Pregnancy and Childbirth Group Trials Register, the Cochrane Controlled Trials Register, other databases and bibliographies of relevant papers are searched according to the strategy developed for the Pregnancy and Childbirth Group as a whole. Date of last search: May 2001. SELECTION CRITERIA: All published or unpublished randomised controlled trials that compare use of an intervention to prevent hypotension with placebo or alternative treatment in patients having spinal anaesthesia for caesarean section. DATA COLLECTION AND ANALYSIS: Trials identified from searching are assessed for inclusion by the same two reviewers independently. Studies are excluded from review for the following reasons: hypotension is not an outcome measure or clearly defined prior to administering a rescue treatment; randomisation is unsatisfactory; the spinal anaesthetic technique or dose of local anaesthetic is not controlled-for; and the intervention is implemented in response to a fall in blood pressure rather than for prevention. Statistical analyses use the Review Manager software for calculation of the treatment effect as represented by the relative risks and proportional and absolute risk reductions. MAIN RESULTS: Twenty trials meet the criteria for inclusion. Four of the twelve interventions reviewed are shown to reduce the incidence of hypotension under spinal anaesthesia for caesarean section: (1) crystalloid 20ml/kg vs control, Relative Risk (RR) 0.78 (95% confidence interval (CI) 0.6, 1.0); (2) pre-emptive colloid administration vs crystalloid, (RR) 0.54 (95% CI 0.37, 0.78); (3) ephedrine vs control, RR 0.70 (95% CI 0.57, 0.85); and (4) lower limb compression vs control, RR 0.75 (95% CI 0.59, 0.94). There are no significant differences in maternal or neonatal side effects in any of the comparisons studied. REVIEWER'S CONCLUSIONS: No studied intervention has been shown to eliminate the need to treat maternal hypotension during spinal anaesthesia for caesarean section. We are unable to draw any conclusions regarding adverse effects of the studied interventions, due to their probable low incidence and the small number of women studied. Further randomised controlled trials are recommended, in particular assessing a combination of the beneficial interventions, i.e. colloid or crystalloid preloading, parenteral ephedrine administration and leg compression with bandages, stockings or inflatable boots.

Environmental determinants of fruit and vegetable consumption among adults: a systematic review.

The current ecological approach in health behaviour research recognises that health behaviour needs to be understood in a broad environmental context. This has led to an exponential increase in the number of studies on this topic. It is the aim of this systematic review to summarise the existing empirical evidence pertaining to environmental influences on fruit and vegetable (FV) consumption. The environment was defined as 'all factors external to the individual'. Scientific databases and reference lists of selected papers were systematically searched for observational studies among adults (18-60 years old), published in English between 1 January 1980 and 31 December 2004, with environmental factor(s) as independent factor(s), and fruit intake, vegetable intake or FV intake combined as one outcome measure as dependent factor(s). Findings showed there was a great diversity in the environmental factors studied, but that the number of replicated studies for each determinant was limited. Most evidence was found for household income, as people with lower household incomes consistently had a lower FV consumption. Married people had higher intakes than those who were single, whereas having children showed mixed results. Good local availability (e.g. access to one's own vegetable garden, having low food insecurity) seemed to exert a positive influence on intake. Regarding the development of interventions, improved opportunities for sufficient FV consumption among low-income households are likely to lead to improved intakes. For all other environmental factors, more replicated studies are required to examine their influence on FV intake.

Systematic review of the literature on postpartum care: selected contraception methods, postpartum Papanicolaou test, and rubella immunization.

BACKGROUND: The postpartum period is a time when many routine interventions are provided to mothers. This review examined the published evidence for the effectiveness of selected contraceptive methods, Papanicolaou (Pap) tests, and rubella immunization. METHODS: MEDLINE, Cinahl, PsycINFO, and the Cochrane Library were searched for randomized controlled trials of interventions initiated from immediately after birth to 1 year in postnatal women. The initial literature search was done in 1999, and was enhanced in 2003. Studies were categorized and reviewed by topic areas. Data were extracted in a systematic method, and the quality of each study was reviewed. RESULTS: In the 1999 search, 140 studies were randomized controlled trials that met the selection criteria: 5 related to postpartum contraception, 1 to timing of the postpartum Pap test, and 2 to postpartum rubella immunization. In the 2003 searches, 1 additional study related to postpartum contraception was identified. From the published literature on selected contraceptive methods, the intrauterine devices examined were effective in preventing pregnancy and had comparable side effect profiles. No clear recommendation can be made because insertion timing was not randomized in the included trials. Although delaying the postpartum Pap smear until 8 weeks reduces the proportion of inflammatory smears, it is uncertain whether a Pap smear is of benefit to postpartum women. The RA 27/3 postpartum rubella vaccine appears to be more effective than the Cendehill vaccine, but a small proportion of women may develop acute and chronic joint manifestations. CONCLUSIONS: Some evidence is available to support selected postpartum contraceptive methods and the postpartum rubella vaccine, but data are lacking on the effectiveness and optimal timing of the postpartum Pap smear.

Clomiphene citrate for unexplained subfertility in women.

OBJECTIVES: Clomiphene citrate appears to increase ovulation in women with oligo-ovulatory subfertility. It may also work in women with unexplained subfertility, perhaps by correcting an unidentifiable ovulatory dysfunction. The objective of this review was to assess the effects of clomiphene citrate in women with unexplained subfertility. SEARCH STRATEGY: The Cochrane Subfertility Review Group specialised register of controlled trials was searched". SELECTION CRITERIA: Randomised trials of clomiphene citrate (doses of 50 to 250 milligrams per day up to 10 days) compared to placebo or no treatment in women with unexplained subfertility. DATA COLLECTION AND ANALYSIS: Trial quality was assessed and data were extracted independently by two reviewers. MAIN RESULTS: Five studies were included. Four trials were of crossover design, and quality of the randomisation was variable. Compared to placebo, clomiphene citrate was associated with an increase in pregnancy rates. The odds ratio for pregnancy per patient was 2.38 (95% confidence interval 1.22 to 4.62). The odds ratio of pregnancy per cycle was 2.5 (95% confidence interval 1.35 to 4.62). REVIEWER'S CONCLUSIONS: Clomiphene citrate appears to modestly improve pregnancy rates in women with unexplained subfertility. However adverse effects include a possible ovarian cancer risk and risk of multiple pregnancy.

Miscellaneous treatments for neuroleptic-induced tardive dyskinesia.

BACKGROUND: Tardive dyskinesia (TD) is a disabling movement disorder associated with the prolonged use of neuroleptic medication. This review, one in a series examining the treatment of tardive dyskinesia, will cover miscellaneous treatments not covered elsewhere. OBJECTIVES: The primary objective of this review was to determine whether the following interventions were associated with a reduction of TD in people with schizophrenia, or others chronic mental illnesses: botulin toxin, endorphin, estrogen, essential fatty acid, EX11582A, ganglioside, lithium, naloxone, periactin, phenylalanine, piracetam, stepholidine, tryptophan, neurosurgery, or ECT. SEARCH STRATEGY: Electronic searches of Biological Abstracts (1982-1995), Cochrane Schizophrenia Group's Register of trials (1995), EMBASE (1980-1995), LILACS (1982-1996), MEDLINE (1966-1995), PsycLIT (1974-1995), and SCISEARCH (1995) were undertaken. References of all identified studies were searched for further trial citations. Principal authors of trials were contacted. SELECTION CRITERIA: The inclusion criteria for all relevant randomised studies were that they should focus on people with schizophrenia or other chronic mental illnesses, with neuroleptic-induced TD and compare the use of the interventions listed above versus placebo or no intervention. DATA COLLECTION AND ANALYSIS: Forty references describing 31 different trials were identified by the search strategy. Of 31 trials, 15 trials were excluded, six trials were included, eight awaiting assessment and a further two trials are pending (awaiting translation, unable to locate). Data were independently extracted by each reviewer and the odds ratio or the average differences were estimated. The reviewers assumed that people who dropped out had no improvement. MAIN RESULTS: Data were available about the efficacy and safety of cerultide, essential fatty acids, estrogen, lithium and insulin. There was a significant improvement in TD associated with the use of insulin compared to placebo (OR = 0.04, 95%CI 0.01-0.24). No significant differences between the other compounds and placebo were identified. REVIEWER'S CONCLUSIONS: There is no strong evidence to support the use of any of the agents included in this review, however because of the small sample sizes, all results must be considered inconclusive. The association between low dose insulin and improvement of TD requires replication.

Long-chain polyunsaturated fatty acid supplementation in infants born at term.

BACKGROUND: This section is under preparation and will be included in the next issue. OBJECTIVES: The n-3 and n-6 essential fatty acids alpha linolenic acid and linoleic acid are the precursors of the n-3 and n-6 longchain polyunsaturated fatty acids (LCPUFA). Controversy exists over whether LCPUFA are essential nutrients during infancy. The aim of this review is to assess whether supplementation of formula with LCPUFA is safe and of benefit to term infants. SEARCH STRATEGY: Trials were identified by MEDLINE, checking reference lists of articles and conference proceedings, and by personal communication. SELECTION CRITERIA: All randomised trials of formula supplemented with LCPUFA and with clinical endpoints were reviewed. DATA COLLECTION AND ANALYSIS: Eight randomised studies were identified. One of these studies was excluded due to supplementation commencing after three weeks of age, and one is awaiting assessment. The remaining six trials were assessed to be of good quality. MAIN RESULTS: Visual acuity was assessed by visual evoked potentials at 4 and 7-8 months in the studies of Makrides et al (1995 & 1996). The supplemented infants had an improved rate of visual maturation at both time points in the first study, but no difference was found between the groups at 4 months in the second study. Visual acuity was assessed by Teller acuity cards in the study of Carlson et al (1996), Clausen et al (1996) and Austed et al (1997). Supplementation had no consistent effect on visual acuity over the first year of life. General development was measured in five studies, all with small numbers. Two suggested a benefit of supplementation. One reported a benefit with supplementation at 4 months ( developmental quotient, DQ measured with the Brunet Lezine test, Agostini et al 1995), but when the groups were reassessed with the same test at 1 and 2 years, no differences were found in DQ (Agostini et al 1997). The other study reported a benefit with supplementation at 9 months (novelty preference measured by Fagan Infantest, Clausen et al 1996). The Adelaide studies showed no effect of supplementation on DQ at one year (Bayley Scales of Infant Development (BSID), Makrides et al 1995 &1996). The Portland study showed no effect of supplementation on development at one year (BSID) or at three years (Stanford Binet IQ test). The Portland study showed no effect of supplementation on language development at one year (McArthur Communicative Development Inventory, Janowsky et al 1995) or at three years (Peabody Picture Vocabulary Test, Scott et al 1997). Growth was measured in a small number of infants in the studies of Makrides et al (1995 & 1996) and Austed et al (1997). There was no suggestion that LCPUFA supplementation reduced the growth of term infants. REVIEWER'S CONCLUSIONS: At present there is little evidence from randomised trials of LCPUFA supplementation to support the hypothesis that LCPUFA supplementation confers any benefit on visual or cognitive development. There are no data from the randomised trials presently available to indicate that LCPUFA supplements influence the growth of term infants.
