重度磨耗患者髁道运动学初步评价

评价重度磨耗患者后方髁道运动学特征 ,探讨髁状突运动与牙合重建的关系。方法 :运用Pantronic髁状突运动描记系统和D5ADenar全调节式咬合架 ,对 15例中老年重度磨耗患者后方髁道决定因素对牙合运动的影响 ,以及对 5例已完成咬合重建的重度磨耗患者髁道运动学特征进行初步评价。结果 :15例重度磨耗患者平均髁间距离为 ( 60 .72± 4.40 )mm ,迅即侧移量 (ISS) 1.3 5mm (右 )和 1.2 4mm (左 ) ,渐进侧移量 (PSS)为14 .65°(右 )与 17.11°(左 ) ,前伸髁导斜度 (PRO)为 2 3 .45°(右 )与 2 6.85°(左 ) ,非工作侧髁道值 (ORB)为 2 6.5 0° ,前伸髁导斜度与非工作侧髁道之间极相关 ,存在较小的Fisher角。结论 :咬合重建主要影响侧移量和Pantronic重复运动指数 (PRI)的大小 ,反映出下颌侧方边缘运动限制所恢复的程度。但牙合重建对非工作侧髁道没有明显的影响 ,运动道的变化并不能预测治疗的效果。

Outcome of a conservative approach in severe ulcerative colitis.

BACKGROUND: Severe ulcerative colitis is potentially life threatening even though a policy of intensive medical management and early colectomy in recent years reduced mortality to almost zero. However, colectomy, with or without ileal-anal anastomosis, has its own problems (morbidity, pouchitis, cuffitis) and no reliable prognostic index of surgical outcome has been developed. Intravenous steroids are still the mainstay of medical therapy but their maximal duration before stating a 'treatment failure' has not been defined. AIM OF THE STUDY: To evaluate the effectiveness, safety and outcome of an intensive medical approach in a series of patients with severe ulcerative colitis. PATIENTS AND METHODS: One hundred and forty-nine episodes of severe ulcerative colitis in 115 patients admitted to a Gastroenterology Unit in a 7-year period were retrospectively evaluated. Intravenous glucocorticosteroids--methylprednisolone 1 mg/kg/day--and topical steroids were administered, and supportive treatments with intensive monitoring were extended to all the patients. Second-line strategies for steroid-refractoriness were prolonged glucocorticosteroids treatment, oral ciclosporin, infliximab or surgery. RESULTS: The median number of Truelove criteria at admission was 3 (range 2-5), median CRP 34 mg/l (range 10-196). Median follow-up after discharge was 49 months. In 84 (57%) episodes an early response was noted, while 65 (43%) did not respond within 10 days to the standard steroid treatment. In the non-responders group, 28 patients went into remission with a prolonged steroid treatment (slow responders); 15 patients were treated with ciclosporin (eight responders) and 6 with infliximab (four responders). A total of 24 colectomies was performed in this group of patients (in 21 cases within 30 days from admission). Slow responders showed lower albumin levels (P = 0.02), higher cumulative dose of glucocorticosteroids in the year prior to admission (P = 0.02) and higher age (P = 0.03), in comparison with early responders. Major complications were noted in four episodes which responded to medical treatment. Disease-related mortality was zero. CONCLUSIONS: Medical treatment and use of second-line therapies were effective in the present series of patients. A group of slow responders has been identified and, if an intensive medical monitoring is guaranteed, steroids can be safely prolonged after the first 10 days of treatment. Cumulatively, about 80% of the patients responded to short-term medical treatment, only 5% of the patients underwent colectomy in the follow-up period. Major adverse events were recorded in four patients, who had recovered completely after adequate medical treatment.     

某医院传染性非典型肺炎疫情分析

目的：分析某医院SARS疫情的发生、发展及控制过程，为疫情控制提供一定的参考依据。方法：依照卫生部推荐的统一个案调查表和临床诊断标准，描述疫情的三间分布以及发放防护用品的数量与病例数的关系。结果：某医院疫情暴发曲线由3个暴发高峰组成，前两个峰较大，后一个峰较小，呈散发。提示病例传染共形成“三代”流行。结论：采用严密的综合防护措施，能够彻底控制SARS疫情在医院的暴发。     

SARS胸部影像表现与评价(附75例分析)

目的：回顾分析75例严重急性呼吸综合症(SARS)病例，探讨该病影像学表现及其与临床治疗有关的问题。方法：全部75例患者均行胸片检查，一般隔日行影像追踪复查。结果：胸部X线表现为肺实质渗出病灶为主，肺内网状改变及肺门片块影较少。影像表现与临床病程有一定关系。结论：胸部影像表现以肺实质渗出病灶较常见。胸片检查是进行本病诊断和评估病程及疗效的重要方法。
