Downward deviation of progressive addition lenses in a myopia control trial

PURPOSE: To clarify how the downward deviation of progressive addition lenses (PALs) reduces their near-addition effect in schoolchildren participating in a myopia control trial. METHODS: Among 95 schoolchildren wearing PALs for 6 months (age range: 6-12 years; refractive error range: -6.00 to -1.25 D), facial images were captured with a digital still camera placed 60 cm in front of the eyes while he or she was looking ahead with natural head posture. The vertical deviations of PALs from their ideal position (mm) were evaluated by analysing these images. RESULTS: The mean (+/-SD) downward deviations of PALs for the right and left eyes were 3.7 +/- 2.3 and 3.7 +/- 2.0 mm, respectively, and the largest downward deviation was 10.2 mm. For simulations using the average downward deviation, the near-addition effect of PALs was reduced to 30 and 63% of the expected value at the 10 degrees and 20 degrees downward eye positions, respectively. CONCLUSIONS: The downward deviation of PALs is a significant factor in reducing their therapeutic effect for near-addition. To ensure the proper alignment of PALs in children, the conventional spectacle-frame-fitting procedure is not sufficient, and repeated confirmation using a testing method similar to that used in this study is required.     

哺乳妇女单次注射迪波盖司通~长效避孕针后血清和乳液中MPA浓度变化

目的:探讨中国妇女哺乳期使用迪波盖司通后血清和乳液醋酸甲羟孕酮(MPA)浓度变化。方法:10名产后哺乳妇女单次注射迪波盖司通(含MPA150mg),在注射后的第1、2、4、6、8、10和12周采集血样和乳液样本,用放射免疫方法测定MPA。结果:血清MPA浓度于注射后第1周最高,到第2、4周时下降明显,第4周后浓度下降趋势逐渐缓慢。乳液MPA浓度在第1周为最高,第2周比第1周降低了约1/2,之后10周平均浓度变化波动在5.09-8.15ng/ml之间。观察期间乳液/血清MPA浓度比值和曲线下浓度面积比值均为0.55。对象之间和同一对象不同时间点乳液/血清MPA浓度存在明显个体差异。结论:哺乳期使用迪波盖司通,将导致血液和乳液中含有一定量的MPA。

安桃乐气体吸入在分娩镇痛中对母婴影响的观察分析

目的:探讨安桃乐(ENTONOX)气体吸入对分娩镇痛及母婴结局的影响。方法:将181名无产科或内科合并症的住院产妇随机分成两组,一组由家属全程陪护,另一组由家属全程陪护+安桃乐气体吸入,观察两组产妇的镇痛效果、产程进展、分娩方式、新生儿Apgar评分情况、产后出血量。结果:ENTONOX吸入对分娩镇痛有效率达98.2％,显效率达80.7％,对产程进展有促进作用,对分娩方式、围产儿结局、产后出血量无显著性差异。结论:ENTONOX吸入镇痛是一种安全、有效的辅助分娩技术,作用迅速、费用低廉,是产妇乐意接受的镇痛方法。     

ROMEO: rethink organization to improve education and outcomes.

AIMS: Scarcity of resources, expertise and evidence-based models have so far limited delivery of patient-centred diabetes education. We have developed and validated a group care approach that is applicable to everyday clinical practice and cost-effective in improving metabolic control, knowledge of diabetes, health behaviours, and quality of life in Type 2 diabetes. A clinical trial (ROMEO) was planned to evaluate applicability and reproducibility of group care in other outpatients facilities and assess its impact on a larger patient population. METHODS: Multicentre, randomized, controlled clinical trial of group vs. individual care in the routine management of Type 2 diabetes. Nine hundred patient aged < 80, with diabetes of > or =1 year known duration, treated by either diet alone or diet and oral agents, will be recruited in 15 centres and followed for 4 years. Training of physicians, nurses and dietitians included preparation of operating manual and videos, interactive sessions, and evaluation of local facilities and resources. RESULTS: Primary measurements: 3-monthly HbA1c, fasting blood glucose, body weight, waist-hip ratio, yearly blood lipids, and bi-yearly assessment of knowledge of diabetes, health behaviours and quality of life. Secondary outcomes: systolic and diastolic blood pressure, evaluation of ECG for ischaemia and QT interval, hypoglycaemic and anti-hypertensive medication and cardiovascular events. Analysis will be by intention-to-treat. DISCUSSION: If ROMEO confirms that group care can be successfully implemented in different clinics, a novel clinico-pedagogic tool will have been acquired to support patient-centred education, improve lifestyle and outcomes, support team work, enhance providers' attitudes and competencies and ameliorate diabetes care organization.
