目的提高药物过敏致急性肺水肿的临床诊断率。方法对35例药物过敏致急性肺水肿患者的影像学检查结果进行回顾性分析。结果数字X线成像检查示Kerley氏B线14例,广泛密度均匀的实变阴影(白肺征)、肺血重新分布及肺纹理及肺门血管增粗、模糊各35例,支气管袖口症、胸腔积液、胸膜增厚各6例,肺泡实变阴影28例,蝶翼征15例,肺内有毛玻璃密度影像(雾蔼征)27例。16排螺旋CT检查表现为小叶间隔增厚,边缘光滑;支气管血管束增粗,光滑;肺内有毛玻璃密度影像。叶间胸膜及其他部位胸膜增厚可发生叶间积液,当病变进展为肺泡性肺水肿时,两肺内有肺泡实变阴影,呈小片状、大片融合状影像,有空气支气管征。结论 X线及CT检查有助于本病早期确诊。
目的 评价电测法+初尖片法在不同根管条件下应用的准确性及影响因素.方法 随机选择临床中完成根管治疗且有完整的病例记录和根尖片的393名患者528颗患牙1296例根管,根据术前片根尖孔的粗细分成根尖孔正常、粗大、细小或闭锁的三种根管,按单独使用电测法(ProPex根管测量仪A组)与使用电测法+初尖片(B组)两种方法,分别对三种根尖孔形态的根管测量其工作长度,进行根管预备,通过试尖过程拍摄主尖片反映的适充情况评价其准确性.结果 根尖孔正常的根管使用两组测量方法测定的准确性之间差异无统计学意义(P＞0.05);测量根尖孔粗大的根管A组适充率是78.69%,低于B(92.31%),P＜0.05.根尖孔细小或闭锁测量的根管A组适充率是85.11%低于B组适充率(91.12%),P＜0.05.结论 初尖片在根管工作长度测量中作用十分必要.
<正>老年性白内障是眼科常见病,但发病过程中其屈光状况的改变报导较少,现将临床确诊为老年性白内障的219人,397只眼测定视力和验光。结果 196只眼不能矫正,201只眼有不同程度的屈光不正,其中远视者136只眼,占67.7%,近视者65眼,占32.3%。1资料与方法本文对眼科门诊中40岁以上的初诊患者均作视力及裂隙
Objective:To explore the chest image appearance in patient with influenza A H1N1 pneumonia.Methods:To collect the imaging findings of 63 patients who were diagnosed with influenza A H1N1,and to retrospectively analyse the imaging characteristics.Results:Among 63 patients with influenza A H1N1,48(76.19%) cases with parenchymal lung lesions,15(23.81%) cases with parenchymal and interstitlal pulmonary diseases,14(22.22%) cases with diffuse pulmonary lesions;Among them,16(25.40%) cases with unilateral lung diseases,47(74.60%) cases with bilateral lung diseases;and 49(77.78%) cases of them with bilateral lung multiple scattered lesions,14(22.22%) cases with focal lesion.25(39.68%) cases manifested as multifocal consolidation.Conclusion:The chief imaging appearances of patients with influenza A H1N1 pneumonia are bilateral lung diseases and multiple patchy shadows,some of them appears as diffuse ground-glass opacity and parenchymal exudation.
笔者自2001年以来,对78例易醒型失眠病例进行了盐酸氟桂利嗪胶囊加舒神灵胶囊中西医结合治疗,取得了良好疗效.现介绍如下:
1临床资料 病例标准 (1)入睡或维持睡眠困难.(2)第(1)症状每周至少发生3次,病期至少1个月,白天疲乏,易激惹,工作效能下降.(3)不只是发生在睡-醒程序紊乱或睡眠异常表现的病程中.(4)除外躯体性疾病或精神障碍症状导致的继发性失眠.(5)年龄大于14岁不超过60岁.(6)曾服苯二氮草类或巴比妥类药物治疗1周以上疗效不满意,每晚睡眠仍不足4h,增加药物剂量患者心理难接受,迫切要求改善治疗者.
目的探讨胆总管结石的超声、磁共振胰胆管成像(MRCP)及X线计算机(CT)的影像学特征,并对比分析3种检查方法的诊断能力及价值。方法52例病例均有完备的超声、CT与MRCP资料。结果以内镜下逆行胰胆管造影术(ERCP)治疗及手术结果为标准,根据诊断试验计算B超、CT、MRCP诊断胆总管结石的敏感度、特异度、假阴性率、假阳性率和准确率。结论诊断胆总管结石CT价值有限,超声与MRCP结合,是诊断胆总管结石的最佳手段。
为探讨下颌阻生第三磨牙的X线表现特征,对1164颗下颌阻生第三磨牙根尖片进行观察及统计分析.结果,阻生牙以近中阻生最多,垂直阻生次之,水平阻生居第三,这三类阻生牙占总数的94.24% ;牙根数目以双根最多,单根次之,多根最少;牙根形态以相对弯曲最多,直根次之,近中弯曲居第三;第二,第三磨牙龋坏与近中阻生关系最为密切.认为通过术前拍片了解牙根数目及形态,是保证顺利拔除该牙的可靠手段,酌情拔除近中阻生的下颌第三磨牙,对于预防下颌第二磨牙龋坏有重要意义.
过去认为脑梗死(Cerebral infaction,CI)多发生于老年人,其病因多为高血压脑动脉硬化,各种心脏病加:心瓣膜病、先天性心脏病、冠心病、心肌梗死、二尖瓣脱垂、心房纤颤等各种原因引起的心力衰竭.糖尿病、吸烟,高脂血症.随着 CT的广泛应用,青壮年脑梗死也不少见,而且病因复杂,除上述常见的病因外还发现了许多新的因素与脑梗死关系密切.如感染、颅脑外伤、低血清胆红素、高同型半胱氨酸血症、偏头痛、脑动脉炎等也可引起 CI.现就以上几种因素引起 CI的情况综述如下.
Objectives To use endoscope to treat choledocholithasis.Methods To use endoscape to finish ERCP and EST under the X ray monitor.Results To use endoscope to treat 65 cases of choledocholithasis diagnosed by ERCP. 64/65 cases were successfully treated by EST. And 63/65(96.7%) were completely purged the stones by grasping basket and balloon catheter.Conclusions (1)ERCP is one of the most important methods to diagnose choledocholithasis.(2) Endoscope can also treat extrahepatic bile duct stones and residual stones after cholecystectomy and choledochotomy.(3) Endscope has the adventages of fewertissue injuries, shorter hospitalization and fewer complications.
