A history of severe allergic reaction to iodine contrast leading to anaphylactic shock presents a dilemma in patients requiring cardiac catheterization. As an alternative, gadolinium has been an interesting and potentially useful agent. However, gadolinium produces poor image quality and has been associated with significant arrhythmias in small case series. Furthermore, there is no consensus about the maximal allowable dose that can be administered to a patient. In the present report, a successful combination of gadolinium contrast with a power injector that produced adequate image quality in a patient with severe allergy to iodine contrast is described. The case was complicated by the occurrence of ventricular fibrillation when damping occurred during injection of contrast into the right coronary artery. This complication has been reported previously with intracoronary gadolinium injection. The report is followed by a brief literature review. 相似文献

遗传代谢病是一大类复杂的单基因病,由于代谢通路异常导致物质代谢紊乱,可以引起单系统或多系统损害.血液系统疾病涉及红细胞、白细胞和血小板功能和数量的异常,其中贫血最常见,新生儿到老年均可发病.现有研究发现,多种遗传代谢病可导致贫血,致病机制不同,一些疾病引起铁、维生素B12、叶酸代谢异常,另一些造成红细胞膜、代谢相关酶或血红蛋白合成异常,引起不同类型不同程度的贫血.为了提高临床医生对遗传代谢病所致贫血及血液系统疾病的认识,早期诊断、精准治疗、改善预后,国内多学科专家共同讨论,结合国内外经验及指南,以巨幼细胞性贫血、溶血性贫血、铁粒幼细胞性贫血和小细胞低色素性贫血四类贫血相关的遗传代谢病的病因、发病机制、临床表现和治疗为重点,制定了本共识,以期指导优化临床诊治实践. 相似文献

Bronchiolitis is the most common reason for admission to hospital in the first year of life. There is tremendous variation in the clinical management of this condition across Canada and around the world, including significant use of unnecessary tests and ineffective therapies. This statement pertains to generally healthy children ≤2 years of age with bronchiolitis. The diagnosis of bronchiolitis is based primarily on the history of illness and physical examination findings. Laboratory investigations are generally unhelpful. Bronchiolitis is a self-limiting disease, usually managed with supportive care at home. Groups at high risk for severe disease are described and guidelines for admission to hospital are presented. Evidence for the efficacy of various therapies is discussed and recommendations are made for management. Monitoring requirements and discharge readiness from hospital are also discussed. 相似文献

Acute myeloid leukaemia (AML) with t(6;9)(p23;q34) is a poor-risk entity, commonly associated with FLT3-ITD (internal tandem duplication). Allogeneic stem-cell tranplantation (allo-SCT) is recommended, although studies analysing the outcome of allo-SCT in this setting are lacking. We selected 195 patients with t(6;9) AML, who received a first allo-SCT between 2000 and 2016 from the EBMT (European Society for Blood and Marrow Transplantation) registry. Disease status at time of allo-SCT was the strongest independent prognostic factor, with a two-year leukaemia-free survival and relapse incidence of 57% and 19% in patients in CR1 (first complete remission), 34% and 33% in CR2 (second complete remission), and 24% and 49% in patients not in remission, respectively (P < 0·001). This study, which represents the largest one available in t(6;9) AML, supports the recommendation to submit these patients to allo-SCT in CR1. 相似文献
