Optic radiation injury in patients with aneurismal subarachnoid hemorrhage: a preliminary diffusion tensor imaging report

Visual field defect is one of the various clinical manifestations in patients with subarachnoid hemorrhage（SAH）. Little is known about the pathogenic mechanism of visual field defect in SAH. In the current study,we investigated the diffusion tensor imaging （DTI） finding of the optic radiation in patients with SAH followingrupture of a cerebral artery aneurysm. We recruited 21 patients with aneurismal SAH （12 males, 9 females, mean age, 52.67 years; range, 41–68 years） who showed no definite lesion along the visual pathway.Twenty-one age-and sex-matched normal control subjects were also recruited. DTI data were acquired at an average of 5.9 weeks （range： 3–12 weeks） after onset and reconstruction of the optic radiation was performed using DTI-Studio software. The fractional anisotropy value, apparent diffusion coefficient value,and fiber number of the optic radiation were measured. The fractional anisotropy value of the optic radiation was significantly decreased, and the apparent diffusion coefficient value was significantly increased, in patients with aneurismal SAH than in normal control subjects. However, there was no significant difference in the fiber number of the optic radiation between patients with aneurismal SAH and normal control subjects. The decrement of fractional anisotropy value and increment of apparent diffusion coefficient value of the optic radiation in patients with aneurismal SAH suggest optic radiation injury. Therefore, we recommend a thorough evaluation for optic radiation injury in patient with aneurismal SAH.

Discrepancies between primary physician practice and treatment guidelines for Helicobacterpylori infection in Korea

瞄准：在 Helicobacter pylori 的诊断和治疗评估主要照顾医生的态度(H。pylori ) 感染。方法：在汉城大城市的区域的主要照顾医生从 1 月回答了自我管理的问询表到 2003 年 3 月。结果：108 位医生对问询表作出回应。为严峻的 H 的最经常的原因。pylori 感染是胃的并且十二指肠溃疡(93.5% 和 88.9% ，分别地) 。为有 H 的病人。pylori 积极消化不良， 28.7% 医生总是试着根除蠕虫并且 34.4% 有选择地对待。主要照顾医生的一个大比例(28.7%) 对待 H。一个病人的请求基础上的 pylori。仅仅， 9.3% 主要照顾医生总是进行了在对待 H 以后测试的后续。pylori 感染。什么时候 H。pylori 没被第一治疗清除， 40.7% 医生再使用一样的政体， 16.7% 改变了到另一三倍的政体并且 25% 到四倍的政体。结论：指南的发行几乎独自没在实践上有很少影响，这很好被记录了。在在连续医药教育形式的主要照顾医生和胃的肠学之间的通讯被要求。
