Orbital injury and complications are commonly encountered in endoscopic sinus surgery (ESS) despite advances in techniques and instrumentation. For the recent 10 years, we summarized the experience of the rhinology unit of our department regarding orbital injury and complications of ESS for sinonasal inflammatory disorders. One thousand seventy-three patients (1869 sides) from January 1, 2003 to December 31, 2012 undergoing ESS for sinonasal inflammatory diseases were enrolled in the present study. The age of the patients ranged from 8 to 81 years, mean age 49 years. Orbital injury and complications were observed in 13 patients (13 sides), which corresponded to 0.7% of the operated sides and 1.2% of the patients. Eight patients showed herniation of orbital fat alone through the injury of the lamina papyracea. The protruding orbital fat was snipped and cut using forceps in 2 patients. Removal of exposed orbital fat using powered instruments was performed in 3 patients, two of whom transiently showed periorbital edema postoperatively. No permanent complications were observed. Meticulous preoperative and perioperative planning is critical to prevent orbital complications. Especially, exposure of the periorbit and herniation of orbital fat after lamina injury with powered instrumentation dramatically increases the potential for more severe complications.

日本已成功建立了全面的社会保障体系,实现了全民医疗和全民年金等目标。该制度的演变跨越了漫长的历史,适应了每个时代的挑战。第二次世界大战结束后,日本采取政策措施为生活贫困者、儿童和残疾人建立了相应的社会救助和社会福利制度。从20世纪50年代末到70年代初,日本完善了全民医疗和全民年金等社会保障制度。自20世纪90年代起,日本开始应对出生率下降和人口老龄化问题,并对社会保障制度进行改革,以确保其可持续性。至此,日本建成了包括医疗、年金、长期护理、育儿支持和公共援助在内的全面社会保障体系以保障民生。然而,在未来老龄化社会的背景下,出生率下降、人口减少以及地区差异的存在,都给政策带来了挑战,包括财政的可持续性、基于社区的医疗和社会服务供给的发展以及应对相对贫困等政策。当前人口减少不仅在日本,在中国和韩国也已成为普遍现象。对中日韩的研究人员来说,探讨人口减少背景下的社会保障等政策选择具有重要意义。

It was reported that hemispheric corrosion occurred in copper tubes in an acetic acid environment. When hemispheric corrosion occurred, corrosion could easily progress if water then flowed into the copper pipe, and countermeasures were needed. Therefore, we studied the copper corrosion caused by acetic acid. The present work investigated the relationship between the corrosion form of copper and acetic acid concentration using phosphorous-deoxidized copper, and reported that hemispherical corrosion was observed at acetic acid concentrations of 0.01 to 1 vol.% (0.002 to 0.2 mol·L-1) in the immersion test. In this study, the effects of acetic acid and phosphate on copper corrosion were examined using oxygen-free copper in immersion tests. The results suggested that different concentrations of phosphate in acetic acid solutions and the presence or absence of acetic acid and phosphate affected the corrosion of copper, resulting in different corrosion forms and corrosion progress.
