Drainage after total thyroidectomy or lobectomy for benign thyroidal disorders

Objective: This prospective randomized clinical trial was conducted to evaluate the necessity of drainage after total thyroidectomy or lobectomy for benign thyroidal disorders. Methods: A total of 116 patients who underwent total thyroidectomy or lobectomy for benign thyroidal disorders were randomly allocated to be drained or not. Operative and postoperative outcomes including operating time, postoperative pain assessed by visual analogue scale (VAS), total amount of intramuscular analgesic administration, hospital stay, complications, necessity for re-operation and satisfaction of patients were all assessed. Results: The mean operating time was similar between two groups (the drained and non-drained groups). The mean VAS score was found to be significantly low in the non-drained group patients in postoperative day (POD) 0 and POD 1. The mean amount of intramuscular analgesic requirement was significantly less in the non-drained group. One case of hematoma, two cases of seroma and three cases of transient hypoparathyroidism occurred in the non-drained group, whereas one case of hematoma, two cases of seroma, two cases of wound infections and two cases of transient hypoparathyroidism occurred in the drained group. No patient needed re-operation for any complication. The mean hospital stay was significantly shorter and the satisfaction of patients was superior in the non-drained group. Conclusion: These findings suggest that postoperative complications cannot be prevented by using drains after total thyroidectomy or lobectomy for benign thyroid disorders. Furthermore, the use of drains may increase postoperative pain and the analgesic requirement, and prolong the hospital stay. In the light of these findings, the routine use of drains might not be necessary after thyroid surgery for benign disorders.

Mathematics in narratives of Geodetic expeditions

In eighteenth-century France, geodesy (the measure of the earth's shape) became an arena where mathematics and narrative intersected productively. Mathematics played a crucial role not only in the measurements and analysis necessary to geodesy but also in the narrative accounts that presented the results of elaborate and expensive expeditions to the reading public. When they returned to France to write these accounts after their travels, mathematician-observers developed a variety of ways to display numbers and mathematical arguments and techniques. The numbers, equations, and diagrams they produced could not be separated from the story of their acquisition. Reading these accounts for the interplay of these two aspects--the mathematical and the narrative--shows how travelers articulated the intellectual and physical difficulties of their work to enhance the value of their results for specialist and lay readers alike.

反季节冬春蔬菜种植农民收益的初步分析——保山市隆阳区潞江坝的实证研究

本文初步对保山市反季节蔬菜进行分析,纵向从蔬菜种子的来源、蔬菜的栽培、蔬菜的收集销售、贮藏和运输这一商品链出发,逐级分析菜农、蔬菜收集人、菜老板的收益分析,从而在整体上揭示菜农在这条商品链上的收益地位;横向同种植其他经济作物,如香烟和甘蔗的收益作对比分析。说明了西部民族山区的广大农户主要收入来源于种植业的现实,农户如何选择种植的经济作物对提高收入有直接的影响,决定农户种植收益除了市场的因素以外各级政府的行政行为则也起到一定的作用。     

排名前10的与预防运动和体育活动猝死相关的关键问题

参加有组织的体育运动和休闲活动存在发生严重伤病甚至死亡的内在风险。虽然造成体育运动或体育活动中猝死的原因有很多,但运动医学和循证标准治疗方面的进展已使临床医生得以更有效地预防、发现和治疗可能致死的伤患。随着研究与技术不断发展进步,当前的治疗标准正在不断发展以更好地改善患者的治疗效果。本文提出了10个与运动和体育活动中猝死的主要原因及其治疗手段有关的关键问题,未来开展的研究将提高运动员和休闲运动爱好者参与运动的安全度。当前证据表明,如采取正确的预防策略或最佳治疗方案,绝大多数的死亡案例是可以避免的。     

要使查寻科技期刊论文方便快捷I.应考虑的诸方面

只有查寻到论文出处，才能见到论文，然而，期刊中的论文查寻常因作者提供的资料含糊不全或编辑和出版者提供的信息不够充分而遇到困难。因此，编辑和出版者有必要为他们期刊中的论文查寻提供方便——他们应遵循某些基本规则。这些规则主要与一种期刊作为一个整体的外观、一期期刊的外观以及每篇论文特别是论文首页的外观有关。对于应考虑的最重要的诸方面都作了阐述。
