异位妊娠诊断治疗进展

异位妊娠是是妇产科常见的急腹症之一，随着高敏感度的血β-HCG测定、阴道超声及腹腔镜临床应用，使异位妊娠得以早期诊断。以往异位妊娠的治疗原则以手术治疗为主．异位妊娠的早期诊断使药物治疗和保守性手术治疗成为可能。     

持续性脑脊液耳漏的诊断与治疗

目的：探讨持续性脑脊液耳漏的发病原因、临床表现、诊断及手术处理方法。方法：分析1987年6月－2000年12月收治26例持续性脑脊液耳漏的临床资料，男16例，女10例。成人18例，儿童8例。结果：26例中自发性脑脊液耳漏14例，因乳突及侧颅底手术引起的12例。15例伴有复发性脑膜炎。26例中25例在我院1次手术修补成功，1例听神经瘤术后脑脊液鼻漏行2次手术修补成功。结论：手术是主要的治疗方法，术中应注意颅底的修复，尤其对内听道、鼓室、咽鼓管、乳突尖等重要部位的处理，以预防术后脑脊液耳漏的发生。     

Clinical aspects and immune reactions in sarcoidosis*

Introduction: Sarcoidosis is a granulomatous disorder of unknown aetiology, affecting young adults and frequently involving the lungs. Objective: The aim of the present review was to give an overview of the clinical aspects in sarcoidosis. Results: The majority of patients recover, but some develop a chronic disease that may result in fibrosis and respiratory failure. Besides the lungs, peripheral lymph nodes, the skin, the liver and the eyes are commonly affected as well. The genetic background, as well as environmental factors, is of importance for developing sarcoidosis. The incidence varies in different populations, in the Nordic countries approximately with 20/100 000 new patients yearly. Sarcoidosis is diagnosed when clinical and radiological findings are supported by histological evidence in the form of non‐caseating epithelioid cell granulomas, and when other causes of these features are excluded. Patients in need of treatment are usually treated with corticosteroids, topically or as oral steroids. A clinical effect of immunomodulatory drugs blocking tumour necrosis factor (TNF)α has been suggested from several case reports, while two controlled studies showed only minor effects; however, with a tendency to a more pronounced effect on patients with a more severe disease. The immune response in sarcoidosis, with a typical accumulation of CD4+ T‐cells to the lungs, indicate the existence of specific antigens in this disease. Recently, antigens derived from infectious agents such as Mycobacteria and Proprionibacterium acnes have come into focus. Lymphocyte populations with immunoregulatory functions have recently been investigated and seem to be dysfunctional in sarcoidosis, opening the possibility of developing new treatment strategies in this disease. Conclusion: Recent technical developments have provided better tools, enabling detailed and more thorough analyses of the inflammatory process in sarcoidosis. Please cite this paper as: Grunewald J.

食管胃吻合口-胸腔瘘的影像学诊断和介入治疗

目的：探讨食管胃吻合口-胸腔瘘的影像学特征及其介入治疗方法。方法：回顾性分析6例具有完整临床资料的食管胃吻合口-胸腔瘘的口服碘水造影及CT表现；透视下，置入蘑菇状覆膜内支架封堵瘘口。结果：6例口服碘水造影显示对比剂均经吻合口溢入胸腔；6例螺旋CT检查，其中5例显示吻合口与胸腔相通，1例瘘口小而未显示。全部病例顺利置入内支架，既完全封堵了瘘口，又解决了进食问题。结论：根据口服碘水造影和螺旋CT征象可以诊断食管胃吻合口-胸腔瘘，置入蘑菇状覆膜内支架封堵瘘口操作简单、安全、近期疗效明显，是一项值得推广的新技术。     

斑点酶联免疫吸附试验检测伤寒特异性抗体

目的　验证斑点酶联免疫吸附试验 (Dot -ELISA)检测伤寒抗体的敏感性和特异性。方法　采用Dot -ELISA测定伤寒沙门菌包膜抗原V、菌体抗原O和鞭毛抗原Hd 的特异性抗体 ,并与肥达氏反应相比较。结果　肥达氏反应均为阴性 ,而经Dot -ELISA试验 ,疑似伤寒患者血清中检出 3种抗体阳性 1例 ,非伤寒发热病人血清中检出单项Hd 抗体阳性1例。Dot -ELISA法比肥达氏反应敏感 10倍以上 ,且无交叉反应。结论　该法有较高的特异性和敏感性 ,且操作简单、快速、无需特殊设备 ,宜于临床推广应用。     

纤维支气管镜对右中叶肺不张的诊治价值(附50例报告)

目的：探讨应用纤维支气管镜检查术在右中叶肺不张诊断和治疗中的价值。方法：对50例右中叶肺不张患者应用纤维支气管镜进行诊断和治疗。结果：50例右中叶肺不张中非特异性炎症29例、肺癌12例、结核3例、异物1例、未确定诊断5例，总确诊率90％(45／50)；50例中33例经纤维支气管镜直视下局部治疗后复张，有效率66％(33／50)，术后未见严重并发症。结论：纤维支气管镜对右中叶肺不张有一定的临床诊断和治疗价值。     

眼眶动静脉畸形致眼上静脉扩张的影像学表现

目的探讨眼眶动静脉畸形(AVM)致眼上静脉(SOV)扩张的影像学及血管造影表现。设计回顾性病例系列。研究对象6例临床表现与硬脑膜海绵窦瘘(CCF)相似的眼眶AVM患者。方法总结分析所有患者的影像学检查结果,如CT、MRI和选择性脑血管造影。主要指标影像学征象及血流动力学。结果CT和MRI均可显示所有患者的SOV扩张。另外,尚存在眼球突出、AVM畸形血管团等征象。所有6例AVM均位于眼眶内,1例尚合并颅内AVM。所有患者的主要引流静脉均为SOV,动脉包括脑膜中动脉、上颌动脉和眼动脉。结论眼眶AVM可引起与CCF相似的临床和影像学征象,但AVM通常不引起海绵窦膨大,血管造影仍是确诊的必需手段,而无创技术是辅助血管造影进行明确诊断的重要手段。(眼科,2007,16:395-398)
