Changing prevalence and knowledge of urinary incontinence among Hong Kong Chinese women

A territory-wide telephone survey was conducted in Hong Kong to assess the prevalence, knowledge, and treatment-seeking behaviour of Chinese women with urinary incontinence, using validated Chinese version of Urogenital Distress Inventory (UDI-6) and Incontinence Impact Questionnaire (IIQ-7). Women, 540, aged between 17 to 77 years were interviewed. Of the respondents, 40.8% reported stress urinary incontinence, 20.4% had urge incontinence and 15.9% had mixed incontinence. Among these, 16.0% reported quality of life impairment; 9.3% felt frustrated with low morale, and 15.2% had nervous and anxiety problems. However, as many as 78.3% of the respondents did not know that stress urinary incontinence is a disease entity, and 60.6% thought that leakage of urine was a normal aging process. For those respondents having stress urinary incontinence, the first treatment of choice was physiotherapy. The second choice was medication, and surgical treatment was the last option. Respondents with stress urinary incontinence showed higher education level.

非糖皮质激素的免疫抑制方案对同种异体移植胰岛的保护作用

目的　评价非糖皮质激素的免疫抑制方案对防止大鼠同种异体胰岛移植排斥反应的效果。方法　大鼠同种异体胰岛移植后 ,分别应用他克莫司 (FK5 0 6 ) 霉酚酸酯 (MMF)和FK5 0 6 MMF 泼尼松 (Pred)行免疫抑制治疗两周 ,并设对照组 ,动态观察受者血糖、胰岛素及C肽变化 ,并作移植部位的形态学检测。结果　FK5 0 6 MMF组和FK5 0 6 MMF Pred组与对照组相比 ,移植胰岛存活时间明显延长 ,移植后 2个月在受者肝汇管区可见较多形态完整的胰岛细胞。FK5 0 6 MMF组维持术后正常血糖、胰岛素及C肽的时间超过 6 0d ,而FK5 0 6 MMF Pred组与前者比较 ,分泌C肽较少 (P <0 .0 5 ) ,血糖维持在较高水平 (P <0 .0 1) ,胰岛素水平两组差异无显著性。FK5 0 6 MMF Pred组停药两周以后的血糖水平较用药期间、停药两周内有明显降低 (P <0 .0 5 ) ,胰岛素和C肽分泌有所增多 ,但差异无显著性。结论　应用FK5 0 6 MMF和FK5 0 6 MMF Pred均有很强的免疫抑制效应 ,但糖皮质激素对胰岛细胞有毒性作用。小剂量FK5 0 6与MMF联用对移植胰岛细胞有较强的保护作用。     

Pedicle screw fixation with translaminar facet joint screws for the treatment of thoracolumbar fracture

Objective:To evaluate the efficacy of Cotrel-Dubeusset (CD) instrumentation combined with translaminar facet joint screw ( TLS ) in the treatment of thoracolumbar fracture. Methods: A total of six L2-L4 spines were used to establish unstable fracture model with three-dimensional range of motion ( ROM ) of the spines measured. Fixation with CD and fixation with CD combined with translaminar facet joint screw were achieved to compare their stability. Thirty cases of thoracolumbar fracture, in whom the anterior edge of vertebral body was compressed to 59% and the posterior edge compressed to 88%, were treated by pedicle screw fixation combined with TLS. Among them, 19 received posterolateral or anterior-posterior bone grafting Results- There was significant difference in ROM between the two techniques except that in extension. In Group CD TLS, ROM was 5.38% lower, lateral bending 4.91% lower and axial rotation 11.85 % lower than those in Group CD respectively. In the clinical group, the average anterior edge restored to 97 % and posterior edge to 98%. The duration of follow-up was 5-24 months (mean, 10 months). The rate of correction loss on the anterior edge was 4.5%. Among the 19 cases of bone grafting, all of them achieved bony fusion (mean fusion time, 4.3 month) with a correction loss rate of 3.4%. Conclusions:In the treatment of thoracolumbar fracture, pedicle screw fixation combined with TLS can strengthen the stability of pedicle screws, especially antirotation stability and enhance fusion rate and reduce correction loss.     

Evaluating the responsiveness of the endometriosis health profile questionnaire: The EHP-30

OBJECTIVES: To evaluate the sensitivity to change of the Endometriosis Health Profile-30 (EHP-30) questionnaire. SETTING: The Women's Center, John Radcliffe Hospital, Oxford. DESIGN: Postal survey to 66 women undergoing conservative surgery for the treatment of endometriosis-associated pain. The EHP-30 and the Short Form-36 (SF-36) were administered 2 weeks before the operation, and 4 months post-operatively. At T2 a transition question was included to evaluate changes in patients health status. To evaluate responsiveness effect sizes, standardised response means, the index of responsiveness and the minimally and clinically important differences were calculated. RESULTS: Forty (66.6%) patients returned the questionnaires at time 1 and 2. Overall less responsive effect size scores were found for the SF-36 (0.1-0.5) compared to the EHP-30 (-0.1-1.1) for all patients who had undergone treatment. Minimally important differences and the index of responsiveness were overall higher for the EHP-30 (0.4-2.0) compared to the SF-36 (0.1-1.0). Change scores for four of the five scales were significantly correlated with women's responses to the transition question. CONCLUSIONS: Results suggest that the EHP-30 is sensitive to change. Its application in clinical trials should prove beneficial in assessing the impact of medical and surgical interventions upon quality of life for women with endometriosis.
