BACKGROUND: We aimed to provide a quantitative analysis of the 1-year clinical outcomes of patients with multisystem coronary artery disease who were included in recent randomized trials of percutaneous coronary intervention with multiple stenting versus coronary artery bypass graft surgery. METHODS: An individual patient database was composed of 4 trials (Arterial Revascularization Therapies Study, Stent or Surgery Trial, Argentine Randomized Trial of Percutaneous Transluminal Coronary Angioplasty Versus Coronary Artery Bypass Surgery in Multivessel Disease 2, and Medicine, Angioplasty, or Surgery Study 2) that compared percutaneous coronary intervention with multiple stenting (N = 1518) versus coronary artery bypass graft surgery (N = 1533). The primary clinical end point of this study was the combined incidence of death, myocardial infarction, and stroke at 1 year after randomization. Secondary combined end points included the incidence of repeat revascularization at 1 year. All analyses were based on the intention-to-treat principle. RESULTS: After 1 year of follow-up, 8.7% of patients randomized to percutaneous coronary intervention with multiple stenting versus 9.1% of patients randomized to coronary artery bypass graft surgery reached the primary clinical end point (hazard ratio 0.95 and 95% confidence interval 0.74-1.2). Repeat revascularization procedures occurred more frequently in patients allocated to percutaneous coronary intervention with multiple stenting compared with coronary artery bypass graft surgery (18% vs 4.4%; hazard ratio 4.4 and 95% confidence interval 3.3-5.9). The percentage of patients who were free from angina was slightly lower after percutaneous coronary intervention with multiple stenting than after coronary artery bypass graft surgery (77% vs 82%; P = .002). CONCLUSIONS: One year after the initial procedure, percutaneous coronary intervention with multiple stenting and coronary artery bypass graft surgery provided a similar degree of protection against death, myocardial infarction, or stroke for patients with multisystem disease. Repeat revascularization procedures remain high after percutaneous coronary intervention, but the difference with coronary artery bypass graft surgery has narrowed in the era of stenting. 相似文献

OBJECTIVE: We describe the mammographic appearance of axillary lymph node calcification in three patients with metastatic ovarian carcinoma. CONCLUSION: Axillary lymph node calcification may be identified mammographically in patients with metastatic ovarian carcinoma and may be evidence of unsuspected metastatic disease. The pattern of calcification differs from that seen with metastatic breast carcinoma. 相似文献

Acute bile duct injury 总被引:7,自引:0,他引:7
Background: An immediate repair is considered optimal in acute biliary duct injuries; however, it may prove to be a challenge, because such repairs are usually performed on small ducts whose viability cannot always be determined. Methods: We performed a retrospective review of the charts of patients with acute bile duct injury who underwent repair at a tertiary care academic university hospital. A total of 204 patients with acute bile duct injury were seen between 1989 and 2002. Of these, 30 were repaired within minutes to hours after the injury. These patients were divided into two groups. Group I patients had a Roux-en-Y hepatojejunostomy below the hepatic junction; Group II patients had a Roux-en-Y hepatojejunostomy at the junction level. We then performed a long-term evaluation of anastomosis function in these patients, using clinical, radiological, and laboratory. Results: Twenty-eight injuries were secondary to a laparoscopy; the other two resulted from open cholecystectomies. All of the patients suffered complex injuries with complete section of the duct and substance loss (Strasberg E). There were 12 patients in group I and 18 in group II. Three cases in group I (25%) and one in group II (5%) developed anastomosis dysfunction. Mean follow-up was 56 months (range, 12–80) in group I and 52 months (range, 10–76) in group II. Two cases in group I (16%) and none in group II (0) required reoperation (p < 0.05). Conclusions: In the acute setting, complex lesions should be treated with a high bilioenteric anastomosis (at the junction level) in the first attempt at repair. Lower-level anastomoses are associated with a higher dysfunction rate and the need for radiological manipulation and reoperation. Also, stenosis of the anastomosis secondary to undetected duct ischemia in the acute repair is more frequent in low bilioenteric anastomoses. 相似文献

Laparoscopic cholecystectomy performed under regional
anesthesia in patients with chronic obstructive pulmonary disease 总被引:1,自引:0,他引:1

Background: Laparoscopic cholecystectomy has been successfully performed using epidural anesthesia. We evaluated our experience
with this surgical approach in high-risk patients. Methods: We present the results of 29 patients with gallstones who, between
1998 and 1999, underwent laparoscopic cholecystectomy with epidural anesthesia. All but 1 patient had chronic obstructive
pulmonary disease. Results: All 29 surgeries were successfully completed via laparoscopy and with the patients under epidural
anesthesia. No patient required endotracheal intubation during surgery or pain medication afterward. Postoperatively, 1 patient
developed a wound infection and 3 patients developed urinary retention. Atlast follow-up (12 months postop), all patients
were in good health. Conclusion: In this series, laparoscopic cholecystectomy was feasible under epidural anesthesia and it
eliminated the need for postoperative analgesia. We believe that this approach should be considered for patients who require
biliary surgery but who are not good candidates for general anesthesia due to cardiorespiratory problems. 相似文献

Due to the presence of two different clones of cells in early embryogenesis, numerous congenital and acquired dermatoses have a linear distribution following the lines of Blaschko. Acquired inflammatory skin diseases are rarely observed in linear patterns. Our patient was born with macrocephaly, left eye glaucoma, and a left facial and contralateral corporal hemihypertrophy, cerebral dysgenesis, and skeletal abnormalities. Hypopigmented S-shaped linear macules on the trunk and linear streaks on the arms and legs were compatible with hypomelanosis of Ito. At 5 years of age the patient presented with an erythematous follicular exanthem compatible with scarlet fever exclusively in the lines of Blaschko. This fact suggests a genetic mosaicism. 相似文献

OBJECTIVE: To evaluate cytokine production and cellular proliferation index (CPI) in peripheral blood mononuclear cells (PBMC) of patients with ankylosing spondylitis (AS), and their association with clinical variables. METHODS: In a cross sectional study we compared the production of tumor necrosis factor-alpha (TNF-alpha), interleukin 1beta (IL-1beta), and IL-10 and CPI in response to phytohemagglutinin (PHA) in PBMC of 27 patients with AS and 24 healthy controls. We also assessed clinical characteristics including disease activity index (BASDAI) and functional index (BASFI). RESULTS: Levels of IL-1beta were higher in patients with AS (median 242 pg/ml) than in controls (median 65 pg/ml); p = 0.002. No differences were observed in median levels of TNF-alpha or IL-10 between AS and controls. Patients had a reduction in CPI (1.2 in AS vs 1.8 in controls; p < 0.001). A positive correlation was observed between IL-10 production and age (rho = 0.34, p = 0.01). A borderline negative correlation was observed between CPI and age (rho = -0.26, p = 0.07). CONCLUSION: Patients with AS had high production of IL-1beta compared with controls and a poor response in CPI. These findings may explain the lack of response for microbial antigens mediated by the innate immune response. 相似文献

BACKGROUND: Use of unmodified interferon alpha-2a in chronic hepatitis C is associated with impaired health-related quality of life during therapy. Treatment with peginterferon alpha-2a (40kD) provides an improved sustained response over unmodified interferon alpha-2a. OBJECTIVES: To compare health-related quality of life during treatment for patients receiving peginterferon alpha-2a (40kD) [Pegasys] versus unmodified interferon alpha-2a [Roferon]. DESIGN: A randomised, international, multicentre, open-label, parallel group study. SETTING: 36 centres worldwide. PATIENTS: Interferon-na?ve patients (n = 531) with chronic hepatitis C. INTERVENTIONS: Peginterferon alpha-2a (40kD) 180 mirog once a week (n = 267) for 48 weeks or unmodified interferon alpha-2a 6 million IU three times a week for 12 weeks followed by 36 weeks of 3 million IU three times a week (n = 264). MEASUREMENTS: Fatigue Severity Scale and 36-item Short-Form Health Survey (SF-36). RESULTS: At weeks 2 and 12, differences favouring peginterferon alpha-2a (40kD) were seen on seven of eight domains and both summary scores of the SF-36 (p < 0.05 to p < 0.01). At weeks 2, 12 and 24, patients receiving peginterferon alpha-2a (40kD) had less disabling fatigue (p < 0.01) than those receiving unmodified interferon alpha-2a. CONCLUSION: Treatment with peginterferon alpha-2a (40kD) is associated with less disabling fatigue and less impairment in patient functioning and well-being during treatment than unmodified interferon alpha-2a. In addition to safety and efficacy, the impact on health-related quality of life may be an important consideration for physicians when selecting an optimal treatment regimen. 相似文献
