Effect of Tropicamide on Laser Flare Meter Measurements in Patients with Pseudoexfoliation

ABSTRACT

Purpose

To investigate the effect of 1% tropicamide on anterior chamber aqueous flare (ACAF) measurements acquired with laser flare meter in patients with pseudoexfoliation.     

Proximal load transfer with a stemless uncemented femoral implant

Bone stock preservation is crucial when performing total hip replacement in young patients. The aim is to save good bone stock for a possible revision procedure. Furthermore, there is an increasing demand from young and active patients to receive a new joint which allows a normal or nearly normal life style. With this in mind, we began, in 1993, to develop a new femoral implant. The purpose of this ultra-short stem was a physiologic strain distribution on the proximal femur with a proximal load transfer from the implant to the femoral bone. Main features were an almost complete absence of the diaphyseal portion of the stem, a well defined lateral flare with load transfer on the lateral column of the femur, and a very high femoral neck cut. These innovations resulted in a conservative implant on both the bone stock and the soft tissues. This implant, in the first years, was recommended only for young and active patients. Over the last thirteen years, this project has undergone several modifications but the basic principles of the implant have remained the same. In the present review, we present the rationale, the surgical technique and the clinical and experimental results so far obtained with this implant.     

Differences in SLE disease activity between patients of Caucasian and South‐East Asian/Chinese background in an Australian hospital

Aim: We performed a semiprospective and retrospective review of all admissions to a single institution of systemic lupus erythematosus (SLE) patients, admitted due to active disease. The aim was to describe differences in disease activity as a cause of hospital admissions between patients originating from South‐East Asia/China (SAC) and Caucasians. Method: There were 210 patients admitted for active disease, with a total of 567 admissions for active SLE over a 16‐year period. Allowing for patients who had left our database, there was a total of 3415 patient years of observation. Results: Patients from SAC with a flare requiring admission presented earlier in their disease course and with more active disease than did Caucasians (median SLE Disease Activity Index 13 vs. 8, P= 0.002). They had longer inpatient stays (7 vs. 5 days P = 0.03). There was a trend to higher rates of re‐presentation to hospital for flare (59% in SAC patients vs. 41% in Caucasians, P = 0.09) with more subsequent admissions (3 vs. 2 P = 0.06) despite a shorter period of observation. Conclusions: South‐East Asian/Chinese were more likely to be diagnosed with class III/IV glomerulonephritis and require cyclophosphamide both at presentation and subsequent admissions. More patients from SAC were readmitted to hospital for severe central nervous system disease after their first hospital admission. In this population, lupus patients had more severe flares and more frequently required admission for these than Caucasians.     

系统性红斑狼疮的肺胸膜损害

分析了系统性红斑狼疮并肺、胸膜损害30例,胸膜改变占首位,共19例,(63.3％),其中胸膜积液16例,合并心包积液3例。其次为SLE肺炎5例(16.7％),尿毒症肺水肿3例(10％),弥漫性肺间质纤维化2例(6.7％),肺不张1例(3.35％)。对临床表现、诊断、治疗和预后进行了讨论。     

白细胞介素6在狼疮性肾炎患者小管间质的表达及其意义

探讨白细胞介素6(IL-6)在狼疮性小管间质病变中的作用。方法 采用ELISA方法与原位分子杂交技术(后者结合IBAS计算机图像分析系统),分别检测42例活动期狼疮性肾炎(LN)患者尿IL-6浓度与其中的15例肾小管间质IL-6mRNA水平。结果 42例活动期LN患者有36例尿IL-6>5pg/mg·cr,其增高程度与尿β_2-m及NAG活性水平呈显著正相关;其中15例肾组织切片中,肾小管间质均有IL-6mRNA表达,并且小管间质病变愈严重,其表达量愈高,而健康肾组织小管间质几无IL-6mRNA表达。结论 LN患者活动期尿IL-6浓度异常增高与肾小管间质IL-6mRNA异常表达有关,提示IL-6在狼疮性小管间质损害过程中可能具有重要作用。     

系统性红斑狼疮女性患者血清CA125,CA199化学发光法测定的临床应用

目的 :探讨系统性红斑狼疮 (SLE)女性患者血清肿瘤标志物CA12 5 ,CA199含量变化及临床意义。方法 :用化学发光法测定 30例正常女性和 38例SLE女性患者血清中CA12 5 ,CA199含量。结果 :正常组CA12 5含量为 11.14± 6 .4 8U/ml,CA199含量为 3.75± 2 .89U/ml;SLE组CA12 5 ,CA199分别为 2 2 .5 6± 2 0 .4 6U/ml,9.5 7± 9.34U/ml。SLE患者CA12 5 ,CA199阳性率分别为 2 1.1% ,7.89%。结论 :SLE患者血清CAl2 5 ,CA199含量较正常组增高 (P <0 .0 5 )。CA12 5 ,CA199在SLE女性患者中可出现阳性 ,对临床诊断SLE有一定价值。     

免疫荧光技术在口腔扁平苔藓和慢性盘状红斑狼疮诊断中的价值

采用免疫荧光技术对口腔扁平苔藓（ＯＬＰ）和慢性盘状红斑狼疮（ＤＬＥ）的免疫病理学进行了研究，结果表明，ＩｇＧ和纤维蛋白原荧光抗体在上皮基底膜区沉积的阳性率两病之间有显著性差异；而胶样小体中出现的阳性率无显著性差异；两病患者的血清抗核抗体阳性率之间亦无显著性差异。
