目的:明确集中的电话干预能否降低慢性心衰门诊患者死亡或因心衰加重而住院的发生率。设计:多中心、随机对照试验。地点:阿根廷的51个中心(包括公立、私立的医院及流动设施)。参与者:1518例患有稳定的慢性心衰且已接受最佳药物治疗方案治疗的门诊患者,由心脏科主治医师分层后随机分为电话干预组和常规治疗组。干预:在常规治疗的基础上,由一个中心通过护士频繁的电话随访对患者进行教育、辅导和监督。主要观察指标:全因死亡或由于心衰加重而住院。结果:99.5%的患者完成了全部随访。常规治疗组758例患者中由于心衰加重而住院或死亡的比例(235…  相似文献

IntroductionSeptal perforation is a condition characterized by loss of cartilage and/or bony structures along with the mucoperichondrium and mucoperiosteum lining them. The etiology includes a history of nasal surgery or trauma, nose picking, bilateral septal cauterization, overuse of nasal sprays, cocaine abuse, vasculitis, and malignancies.ObjectiveComparison of quality of life in patients with septal perforation after conservative or surgical treatment, and a new approach for the determination of the diameter of the perforation from a different point of view.MethodsThe diameter of septal perforation, total vertical diameter of septum, and horizontal diameter of the perforation were measured in a total of 34 patients. Nineteen of the patients underwent surgical septal perforation repair, and 15 of them received septal button application. The patients were asked to complete the Glasgow Benefit Inventory quality of life questionnaire.ResultsThe septal perforation successfully healed in 18 of 19 patients who underwent surgical treatment. The quality of life scores were statistically significantly higher in the surgical treatment group when compared to the button group (p < 0.05).ConclusionThe septal perforation classification we propose would be beneficial for providing realistic dimensions, treatment methods, and surgical techniques.  相似文献

The aim of this study was to describe clinical features of PBD comorbidity in children with ASD. Forty children with ASD and PBD aged 6–18 years, and 40 age- and sex-matched ASD subjects with no affective episodes were included in the study. Autism Behavior CheckList, Abberant Behavior CheckList, and Young Mania Rating Scale-Parent Version were completed. This study shows that PBD comorbidity in children with ASD involves a highly episodic course, with manic episodes, subsyndromal symptoms and interepisodic periods commonly being described in the manic symptom profile of these children. These findings need to be repeated with large samples, together with controlled studies concerning therapeutic interventions directed toward PBD comorbidity in children with ASD.  相似文献

Objective: To investigate the plasma levels of interleukin-4 (IL-4), IL-6, IL-10, tumor necrosis factor-alpha (TNF-alpha), interferon-gamma (IFN-gamma), transforming growth factor-beta (TGF-beta), IL-17, IL-35 and suppressor of cytokine signaling 3 (SOCS3) in the women with history of idiopathic recurrent pregnancy loss (RPL) and in the fertile controls.

Methods: This study was conducted with 60 idiopathic RPL cases and 40 age-matched fertile controls. Mid-follicular plasma levels of IL-17, IFN-gamma, TNF-alpha, TGF-beta, IL-6, IL-4, IL-10, SOCS3 and IL-35 were assayed by an enzyme linked immunosorbent assay.

Results: The mean age of RPL and control cases were 31.6?±?0.6 and 32.1?±?0.7 years, respectively. While plasma IL-35 and SOCS3 levels of RPL group were significantly lower than that of the control group; IFN-gamma, TNF-alpha, IL-4, IL-6, IL-10, IL-17 and TGF-beta levels of RPL group were significantly higher than that of the control group. The comparison of cytokine ratios between RPL and control groups indicated significantly high TNF-alpha/IL-10, TNF-alpha/IL-4, IFN-gamma/IL-10, IFN-gamma/IL-6 and IFN-gamma/IL-4 ratios in the RPL group. IL-35/IL-17 ratio was significantly low in the RPL group compared to that in the control group. Overstimulation of TNF-alpha presented moderate influence on recurrent miscarriage risk.

Conclusion: Decreased SOCS3 and IL-35 plasma levels and increased Th1/Th2 cytokine ratios in RPL cases pointed out the supression of anti-inflammatory process and this supression might play an important role in the pathogenesis of idiopathic RPL.  相似文献

Corticosteroids are a mainstay of topical therapy for psoriasis. While efficacious and relatively safe when used carefully, the potential for side effects, notably skin atrophy and adrenal suppression, have been associated with excesses in potency, prolonged or widespread use. The International Psoriasis Council Working Group on Topical Therapy has reviewed the efficacy and safety of topical corticosteroids and recommends strategies for safe, long‐term use of these agents.  相似文献

OBJECTIVE: To investigate the effectiveness of a single preoperative dose of misoprostol in abdominal myomectomies. DESIGN: Placebo-controlled randomized prospective study. SETTING: Department of obstetrics and gynecology in a university hospital. PATIENT(S): Twenty-five women with symptomatic uterine leiomyomas. INTERVENTION(S): Among patients undergoing abdominal myomectomies, an hour before the operation women in the study group (n = 13) were given a single dose of vaginal misoprostol (400 microg); those in the control group (n = 12) were given placebo. MAIN OUTCOME MEASURE(S): Intraoperative blood loss, duration of operation, duration of postoperative hospitalization, and the need for blood transfusion were compared between the control and study groups. RESULT(S): Blood loss, operation time, and need for postoperative blood transfusion were significantly reduced in the group given vaginal misoprostol. No difference was observed among patients in terms of the time of hospitalization. CONCLUSION(S): A single preoperative dose of vaginal misoprostol is a simple, reliable method for reducing intraoperative blood loss and need for postoperative blood transfusion after abdominal myomectomies.  相似文献
