28例青年人胃癌的临床及病理分析

对２８例青年人胃癌的临床及病理分析结果表明，其发病具有症状隐匿、病程短、进展快的特点，本组病例从出现症状到漏诊在６个月内为５７．１％（１６例），首发症状以上腹部疼痛、吐血、黑便多见，病理特征以结节蕈伞型、高分化腺癌多见。     

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。     

SARS临床特点分析

目的 :探讨SARS的临床特点、诊治方法。方法 :对 2 0 0 3年 3月至 2 0 0 3年 5月收治的 2 9例传染性非典型肺炎患者进行回顾性分析 ,总结其流行病学特点、临床表现、血常规及影像学检查特点。结果 :本组 2 9例全部以发热为首发症状 ,有明确接触史者 2 5例 (占 86 .2 % ) ,第一次血常规白细胞降低者有 8例 (占 2 7.6 % ) ,淋巴细胞计数 <0 .9× 10 9 L者 19例 (占 6 5 .5 % ) ,白细胞计数出现进行性下降者 2 2例 (占 75 .9% )。所有患者胸片显示肺部阴影 ,其中迅速进展者 18例 (占 6 2 .1% )。治疗采用抗病毒、抗感染、支持等综合治疗 ,重症患者使用大剂量甲泼尼龙和无创机械通气。结论 :流行病学史、临床特点是早期诊断的关键 ,治疗采取综合方法 ,对重症患者使用大剂量激素、无创机械通气治疗有效     

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.

垂体脓肿的诊断和治疗(14例报告和文献复习)

目的:探讨垂体脓肿的临床特征和治疗。方法:回顾性分析14例垂体脓肿患者的临床表现、影像学特征、诊断和治疗,并结合文献进行分析。结果:14例患者中头痛13例,垂体功能低下6例,视力视野影响6例,多饮多尿3例,发热3例。MRI增强病灶均呈环状强化。11例经蝶手术治疗,3例经开颅手术。术后随访头痛缓解者10例,视力、视野改善者4例,尿崩者2例恢复正常,垂体功能低下者中4例恢复正常,3例开颅手术者中2例复发,再经蝶手术治愈。结论:应用常规CT和MR术前诊断垂体脓肿困难,对鞍区囊性病变应考虑到垂体脓肿的可能。及早手术、正确选择手术入路、围手术期合理应用抗生素和适当的对症治疗是治疗垂体脓肿的关键。
