BACKGROUND Cross-sectional studies revealed that cigarette smokers have lower high-density lipoprotein cholesterol (HDL-C) levels and higher levels of total cholesterol (TC), low-density lipoprotein cholesterol (LDL-C), and triglycerides (TG) than nonsmokers. But prospective studies on the effects of cigarette smoking cessation on lipid profile have yielded(More)
We performed a meta-analysis of randomized controlled trials to determine the optimal timing of laparoscopic cholecystectomy and open cholecystectomy for acute cholecystitis. We retrieved randomized controlled trials (RCTs) that compared early with delayed cholecystectomy for acute cholecystitis by systematically searching Medline and the Cochrane Library(More)
OBJECTIVES To compare the results of randomized controlled trials versus observational studies in meta-analyses of digestive surgical topics. SUMMARY BACKGROUND DATA While randomized controlled trials have been recognized as providing the highest standard of evidence, claims have been made that observational studies may overestimate treatment benefits.(More)
BACKGROUND AND OBJECTIVES The prophylactic use of protease inhibitors in patients undergoing ERCP is still controversial. Our purpose was to evaluate the efficacy of protease inhibitors in preventing ERCP-associated complications. DESIGN AND SETTING Meta-analysis; randomized trials that evaluated the efficacy of protease inhibitors were identified. (More)
A 51-year-old woman presented with flexion contractures of the legs. Physical examination showed decreased passive movements of the bilateral hip and knee joints without muscle spasms or neurological abnormalities. Laboratory evaluation showed no response of ACTH or plasma cortisol to stimulation with CRH or insulin. Diagnosis of isolated(More)
BACKGROUND Many studies have investigated the usefulness of adenosine deaminase activity (ADA) in pleural fluid for the early diagnosis of tuberculous pleurisy. To summarize the diagnostic characteristics of ADA we undertook a meta-analysis using a summary receiver operating characteristic (SROC) curve method. METHODS Data sources were MEDLINE(More)
BACKGROUND To compare single- with two- layer intestinal anastomosis after intestinal resection: a meta-analysis of randomized controlled trials. METHODS Randomized controlled trials comparing single- with two-layer intestinal anastomosis were identified using a systematic search of Medline, Embase and the Cochrane Library Databases covering articles(More)
BACKGROUND The effectiveness of prophylactic antibiotics use for acute necrotizing pancreatitis has been explored and a number of systematic reviews have been published with conflicting results. The timing of antibiotics administration can be fundamental to their effectiveness, but thus far no reviews have focused on the timing of administration. METHODS(More)
OBJECTIVES Protease inhibitors are used to treat acute pancreatitis, but their effectiveness remains unclear. We performed a meta-analysis to determine whether treatment with protease inhibitors reduces overall mortality or morbidity from acute pancreatitis. METHODS Articles of randomized controlled trials evaluating effects of protease inhibitors for(More)
PURPOSE To perform meta-analysis of literature about the role of helical computed tomography (CT) and ventilation-perfusion (V-P) scanning in detection of acute pulmonary embolism (PE) by using summary receiver operating characteristic (ROC) curve analysis. MATERIALS AND METHODS V-P scanning articles published from January 1985 to March 2003 and helical(More)
