Purpose: To present a patient with bilateral severe and symmetric lower lid lymphedema in the setting of previous neck surgery and chronic psoriasis, and to review the potential relationships of neck surgery, irradiation, psoriasis, and rosacea to chronic lymphedema. Design: Single case report with literature review. Methods: A 60-year-old female with long-standing psoriasis presented with a 2-year history of severe, symmetric bilateral lower eyelid edema that developed after total laryngectomy and selective right neck dissection for recurrent Squamous Cell Carcinoma (SCC). 10 years prior she underwent radiation and radical left neck dissection for metastatic disease. Surgical management entailed transcutaneous debulking of the masses combined with ectropion repair and suture tarsorrhaphy. A comprehensive literature review was performed using Pubmed and Medline. Results: Surgical debulking of the soft tissue masses via a transcutaneous incision resulted in significant improvement in the patient’s lymphedema without recurrence at 5 months follow-up. Histopathologic findings were consistent with chronic eyelid lymphedema. Conclusions: Isolated eyelid lymphedema is rare, with many etiologies, and poses a diagnostic challenge. While ophthalmologists are familiar with the ocular manifestations of rosacea such as conjunctivitis or blepharitis, it is important to consider rosacea as an etiology of eyelid lymphedema. Reviewing the history for previous surgery or radiation to the head and neck, or other dermatologic inflammatory disorders is also warranted. Rosaceous lymphedema is typically less severe than in post-surgical/radiation patients, and does not respond well to medical treatment;however, it often shows a favorable response to debulking blepharoplasty surgery, with or without skin grafting. This patient with a history of severe psoriasis and bilateral neck dissections with radiation for SCC also responded well to surgery without recurrence of lymphedema. Therefore,

中国的快速发展加快了大湄公河次区域大型水电项目的投资,以促进与东亚国家的关系,并重塑区域结构为目标。在此情况,存在的问题是这些发展是否会因通过建立大型技术系统以及其基础政策背后的动机和利益导致中国的“统治”。本研究探讨了中国在大湄公河次区域（GMS）的水电扩张与中国社会技术优势的潜在表现之间的关系。其目标是提供一个新的视角,以了解基础设施的政治层面,以及投资建坝的能力,以促进电力的区域领导/不对称关系。

The BR （Ba River） basin is one of 9 main river basins in Vietnam. In the past 20 years, natural hazards such as flood andinundation have been complex and increased dramatically in both frequency and intensity in the BR basin. Recently, there have beenapproximately 198 large and small operating reservoirs which lead to increase natural hazards in the river basin. An Khe reservoir,one of big reservoirs in the upstream of the Ba river, impacts significantly on flooding in the downstream. This paper useshydrological model to simulate the flows as a basic for the safety operation of An Khe reservoir in order to prevent the downstreamfloods. The results indicate the Nash-Sutcliffe coefficient higher than 0.8 is stable and reliable parameter.
