Controversy exists regarding the benefit of endoscopic carpal tunnel release versus open carpal tunnel release in terms of grip/pinch strength, scar tenderness, pain, return to work, reversible/irreversible nerve damage, and adverse effects. Although a number of randomized controlled trials and systematic reviews have been published on the subject, to date, no large definitive randomized controlled trial or meta-analysis has been performed comparing endoscopic to open carpal tunnel release. This meta-analysis was undertaken to address the effectiveness of endoscopic carpal tunnel release relative to open carpal tunnel release. Key outcome measures from 13 randomized controlled trials were extracted and statistically combined. Heterogeneity was observed in three of the outcomes (i.e., grip strength, pain, and return to work), but the causes of heterogeneity could not be explained because of insufficient detail in the reported studies. Using the Jadad et al. scale, nine of 13 studies were of low methodologic quality. The effect sizes were compared between the studies that were rated as high quality and the studies that were rated as low quality on the Jadad et al. scale. Similarly, the studies that were rated as high quality on the Gerritsen et al. scale were compared with those that were rated as low quality. No clinically significant difference in effect sizes was apparent between studies of high and low methodologic quality. This meta-analysis supports the conclusion that endoscopic carpal tunnel release is favored over the open carpal tunnel release in terms of a reduction in scar tenderness and increase in grip and pinch strength at a 12-week follow-up. With regard to symptom relief and return to work, the data are inconclusive. Irreversible nerve damage is uncommon in either technique; however, there is an increased susceptibility to reversible nerve injury that is three times as likely to occur with endoscopic carpal tunnel release than with open carpal tunnel release. 相似文献

A systematic review of reviews comparing the effectiveness of endoscopic and open carpal tunnel decompression 总被引:2,自引:0,他引:2
Controversy persists regarding the benefit of endoscopic carpal tunnel release compared with open carpal tunnel release for pain, numbness, strength, return to work and function, scar tenderness, and complications. For surgeons, a recommended first source of information on treatment effectiveness is a review of high-methodologic-quality articles. This review of reviews was undertaken to answer this clinical question regarding these outcomes. Cochrane, MEDLINE, EMBASE, CINAHL, and HealthSTAR databases were searched using the key words "endoscopic carpal tunnel," with limits "review or overview" and dates from 1989 to present. Five key journals were hand-searched. Any review with a reference to at least one randomized controlled trial that compared endoscopic carpal tunnel release to open carpal tunnel release was to be included. Two reviewers independently scanned titles and abstracts for potential relevance. Selection as relevant was confirmed through a review of full texts. Disagreements were resolved through discussion and consensus. The selected reviews were assessed for methodologic quality on the basis of the scale of Hoving et al. Of 48 articles initially identified, seven pertinent reviews were selected. Of these seven, three reviews of high methodologic quality concurred that there is no difference between the two techniques in symptom relief and that the evidence is conflicting for return to work and function. The risk of permanent median nerve injury does not differ between the techniques. The reviews indicated that the endoscopic carpal tunnel release technique is worse in terms of reversible nerve injury but superior in terms of grip strength and scar tenderness, at least in short-term follow-up. Several trials have not been incorporated in these reviews and statistical pooling has not been conducted. Further systematic review with meta-analysis may permit more definitive conclusions about the relative effectiveness of these two techniques, particularly with regard to return to work and function. 相似文献

Background
Quality care in health facilities is critical for a sustainable health insurance system because of its influence on clients’ decisions to participate in health insurance and utilize health services. Exploration of the different dimensions of healthcare quality and their associations will help determine more effective quality improvement interventions and health insurance sustainability strategies, especially in resource constrained countries in Africa where universal access to good quality care remains a challenge.Purpose
To examine the differences in perceptions of clients and health staff on quality healthcare and determine if these perceptions are associated with technical quality proxies in health facilities. Implications of the findings for a sustainable National Health Insurance Scheme (NHIS) in Ghana are also discussed.Methods
This is a cross-sectional study in two southern regions in Ghana involving 64 primary health facilities: 1,903 households and 324 health staff. Data collection lasted from March to June, 2012. A Wilcoxon-Mann-Whitney test was performed to determine differences in client and health staff perceptions of quality healthcare. Spearman’s rank correlation test was used to ascertain associations between perceived and technical quality care proxies in health facilities, and ordered logistic regression employed to predict the determinants of client and staff-perceived quality healthcare.Results
Negative association was found between technical quality and client-perceived quality care (coef. = -0.0991, p<0.0001). Significant staff-client perception differences were found in all healthcare quality proxies, suggesting some level of unbalanced commitment to quality improvement and potential information asymmetry between clients and service providers. Overall, the findings suggest that increased efforts towards technical quality care alone will not necessarily translate into better client-perceived quality care and willingness to utilize health services in NHIS-accredited health facilities.Conclusion
There is the need to intensify client education and balanced commitment to technical and perceived quality improvement efforts. This will help enhance client confidence in Ghana’s healthcare system, stimulate active participation in the national health insurance, increase healthcare utilization and ultimately improve public health outcomes. 相似文献6.
Despite recent advances in modeling forest–rainfall relationships, the current understanding of changes in observed rainfall patterns resulting from historical deforestation remains limited. To address this knowledge gap, we analyzed how 40 years of deforestation has altered rainfall patterns in South America as well as how current Amazonian forest cover sustains rainfall. First, we develop a spatiotemporal neural network model to simulate rainfall as a function of vegetation and climate inputs in South America; second, we assess the rainfall effects of observed deforestation in South America during the periods 1982–2020 and 2000–2020; third, we assess the potential rainfall changes in the Amazon biome under two deforestation scenarios. We find that, on average, cumulative deforestation in South America from 1982 to 2020 has reduced rainfall over the period 2016–2020 by 18% over deforested areas, and by 9% over non-deforested areas across South America. We also find that more recent deforestation, that is, from 2000 to 2020, has reduced rainfall over the period 2016–2020 by 10% over deforested areas and by 5% over non-deforested areas. Deforestation between 1982 and 2020 has led to a doubling in the area experiencing a minimum dry season of 4 months in the Amazon biome. Similarly, in the Cerrado region, there has been a corresponding doubling in the area with a minimum dry season of 7 months. These changes are compared to a hypothetical scenario where no deforestation occurred. Complete conversion of all Amazon forest land outside protected areas would reduce average annual rainfall in the Amazon by 36% and complete deforestation of all forest cover including protected areas would reduce average annual rainfall in the Amazon by 68%. Our findings emphasize the urgent need for effective conservation measures to safeguard both forest ecosystems and sustainable agricultural practices. 相似文献

BACKGROUND: Little information is available in Canada about the prevalence of and outcomes associated with a history of slapping and spanking in childhood. The objectives of this study were to estimate the prevalence of a history of slapping or spanking in a general population sample and to assess the relation between such a history and the lifetime prevalence of psychiatric disorders. METHODS: In this general population survey, a probability sample of 9953 residents of Ontario aged 15 years and older who participated in the Ontario Health Supplement was used to examine the prevalence of a history of slapping and spanking. A subgroup of this sample (n = 4888), which comprised people aged 15 to 64 years who did not report a history of physical or sexual abuse during childhood, was used to assess the relation between a history of slapping or spanking and the lifetime prevalence of 4 categories of psychiatric disorder. The measures included a self-administered questionnaire with a question about frequency of slapping and spanking during childhood, as well as an interviewer-administered questionnaire to measure psychiatric disorder. RESULTS: The majority of respondents indicated that they had been slapped or spanked, or both, by an adult during childhood "sometimes" (33.4%) or "rarely" (40.9%); 5.5% reported that this occurred "often." The remainder (20.2%) reported "never" experiencing these behaviours. Among the respondents without a history of physical or sexual abuse during childhood, those who reported being slapped or spanked "often" or "sometimes" had significantly higher lifetime rates of anxiety disorders (adjusted odds ratio [OR] 1.43, 95% confidence interval [CI] 1.04-1.96), alcohol abuse or dependence (adjusted OR 2.02, 95% CI 1.27-3.21) and one or more externalizing problems (adjusted OR 2.08, 95% CI 1.36-3.16), compared with those who reported "never" being slapped or spanked. There was also an association between a history of slapping or spanking and major depression, but it was not statistically significant (adjusted OR 1.64, 95% CI 0.96-2.80). INTERPRETATION: There appears to be a linear association between the frequency of slapping and spanking during childhood and a lifetime prevalence of anxiety disorder, alcohol abuse or dependence and externalizing problems. 相似文献

Background
Medicinal plants are used by 80% of people from developing countries to fulfill their primary health needs, occupying a key position on plant research and medicine. Taking into account that, besides their pharmaceutical importance, these plants contribute greatly to ecosystems' stability, a continuous documentation and preservation of traditional knowledge is a priority. The objective of this study was to organize a database of medicinal plants including their applications and associated procedures in Canhane village, district of Massingir, province of Gaza, Mozambique.Methods
In order to gather information about indigenous medicinal plants and to maximize the collection of local knowledge, eleven informants were selected taking into account the dimension of the site and the fact that the vegetation presents a great homogeneity. The data were collected through intensive structured and semi-structured interviews performed during field research. Taxonomical identification of plant species was based on field observations and herbarium collections.Results
A total of 53 plant species have been reported, which were used to treat 50 different human health problems. More than half of the species were used for stomach and intestine related disturbances (including major diseases such as diarrhea and dysentery). Additionally, four species with therapeutic applications were reported for the first time, whose potential can further be exploited. The great majority of the identified species was also associated with beliefs and myths and/or used as food. In general, the community was conscientious and motivated about conservational issues and has adopted measures for the rational use of medicinal plants.Conclusions
The ethnomedicinal use of plant species was documented in the Canhane village. The local community had a rich ethnobotanical knowledge and adopted sound management conservation practices. The data compiled in this study show the social importance of the surveyed plants being a contribution to the documentation of PGR at the national and regional level. 相似文献9.

This study compared the deep inferior epigastric perforator (DIEP) flap and the free transverse rectus abdominis myocutaneous (TRAM) flap in postmastectomy reconstruction using a cost-effectiveness analysis. A decision analytic model was used. Medical costs associated with the two techniques were estimated from the Ontario Ministry of Health Schedule of Benefits for 2002. Hospital costs were obtained from St. Joseph's Healthcare, a university teaching hospital in Hamilton, Ontario, Canada. The utilities of clinically important health states related to breast reconstruction were obtained from 32 "experts" across Canada and converted into quality-adjusted life years. The probabilities of these various clinically important health states being associated with the DIEP and free TRAM flaps were obtained after a thorough review of the literature. The DIEP flap was more costly than the free TRAM flap ($7026.47 versus $6508.29), but it provided more quality-adjusted life years than the free TRAM flap (28.88 years versus 28.53 years). The baseline incremental cost-utility ratio was $1464.30 per quality-adjusted life year, favoring adoption of the DIEP flap. Sensitivity analyses were performed by assuming that the probabilities of occurrence of hernia, abdominal bulging, total flap loss, operating room time, and hospital stay were identical with the DIEP and free TRAM techniques. By assuming that the probability of postoperative hernia for the DIEP flap increased from 0.008 to 0.054 (same as for TRAM flap), the incremental cost-utility ratio changed to $1435.00 per quality-adjusted life year. A sensitivity analysis was performed for the complication of hernia because the DIEP flap allegedly diminishes this complication. Increasing the probability of abdominal bulge from 0.041 to 0.103 for the DIEP flap changed the ratio to $2731.78 per quality-adjusted life year. When the probability of total flap failure was increased from 0.014 to 0.016, the ratio changed to $1384.01 per quality-adjusted life year. When the time in the operating room was assumed to be the same for both flaps, the ratio changed to $4026.57 per quality-adjusted life year. If the hospital stay was assumed to be the same for both flaps, the ratio changed to $1944.30 per quality-adjusted life year. On the basis of the baseline calculation and sensitivity analyses, the DIEP flap remained a cost-effective procedure. Thus, adoption of this new technique for postmastectomy reconstruction is warranted in the Canadian health care system. 相似文献
