  • Background: Eosinophilic pleural effusion (EPE) is an eosinophil count more than 10% on cytology of pleural samples. Recently, it was reported that malignancy had been the most prevalent cause inducing EPE. Therefore, we conducted an analysis on the prevalence and etiology of EPE and investigated the relationship between EPE and malignancy. Materials and Methods: Data for pleural cell differential count from patients receiving thoracentesis during the period from January 2008 to December 2013 were compared with clinical data and established diagnosis of patients obtained via electronic chart review. Results: A total of 6,801 requests of pleural cytology from 3,942 patients with pleural effusion who had received thoracentesis were available at Far Eastern Memorial Hospital from 2008 to 2013, and of these subjects, 115 (2.9%) were found to have EPE. The most frequent cause of EPE was malignancy (33.0%, n=38), followed by parapneumonic effusions (27.8%, n=32), tuberculosis pleuritis (13.9%, n=16), transudate effusions (12.2%, n=14) and the presence of blood or air in pleural space (10.4%, n=12). Additionally, an inverse relationship of eosinophilia in pleural fluid was identified in patients with malignancy and EPE. The cut-off eosinophil count in pleural fluid was 15% for the most accurate discrimination between malignancy and benign disorders in patients with EPE. At the cut-off level, the sensitivity and specificity were 65.8% and 67.5%, respectively. Conclusions: Pleural fluid eosinophilia was a speculative negative predictor for malignancy, despite the fact that cancers, including lung cancers and metastatic cancers to lung, were the most leading cause of pleural fluid eosinophilia. An inverse correlation was observed between the pleural eosinophil percentage and the likelihood of malignancy in patients with EPE.

  • Spinal subdural hematoma[SSDH] is rare disease. Furthermore, it rarely occurs as a complication of intracranial surgery. There are few case reports which describing SSDH after craniotomy. Although the exact pathogenetic mechanism is obscure, some investigators propose that downward migration of intracranial hematoma by the effect of gravity is one of the cause of SSDH, and which is commonly suggested. But others propose that cerebrospinal fluid[CSF] hypotension is an another possible mechanism In this paper, we report two cases of SSDH after clipping of an aneurysmal neck.

  • Objective: Computed tomography following myelography (CTM) revealed an unusual flow of contrast dye into the anterior median fissure (AMF) in a patient with cervical spondylotic myelopathy. Since then, several AMF configurations have been observed on CTM. Therefore, we evaluated morphological patterns of the AMF on CTM and investigated the significance and mechanisms of contrast dye flow into the AMF. Methods: Morphological patterns of the AMF on CTM were examined in 79 patients. Group A (24 patients) underwent surgery because of symptomatic cervical myelopathy. Group B (43 patients) had no clinical symptoms but showed spinal cord compression on CTM. Group C (12 patients), who showed neither clinical symptoms nor cord changes, underwent CTM for lumbar lesion evaluation. AMF patterns were classified into 4 types according to their configurations on CTM (reversed T, Y, V, and O types). Results: In group B, the reversed T type and Y type appeared significantly more often near the compressed portion (p<0.001). A similar tendency was seen in group A. The V and O types were most frequently observed in group C (p<0.001). Conclusion: On CTM, contrast dye tends to flow into the AMF of the cervical cord when the spinal cord is compressed. We speculate that there may be 3 possible mechanisms for this phenomenon: deformation of the epipial layer of the AMF due to cervical cord compression, AMF dilatation due to atrophy of the anterior funiculus or anterior horn, and temporary AMF dilatation when it becomes an alternative route for cerebrospinal fluid circulation.

  • Objective : A retrograde clinical study was undertaken to determine the effect of opening lamina terminalis on the development of hydrocephalus after aneurysmal subarachnoid hemorrhage(SAH). We compared the incidence ratios of the development of hydrocephalus with and without opening lamina terminalis during operation after aneurysmal SAH. Patients and Methods : From Oct. 1996 to Sep. 1998, we performed 138 aneurysm surgery for 122 patients. In 98 cases, the lamina terminalis was opened to make direct cerebrospinal fluid flow from the third ventricle to subarachnoid space for prevention of delayed hydrocephalus. We compared the incidence of hydrocephalus after opening lamina terminalis to those without opened lamina terminalis. Results : In 95 cases, the hydrocephalus was noticed in 2 cases(2.2%). It is significantly lower in the group with opening lamina terminalis than the group without opening lamina terminalis(about 10%). Conclusion : It is simple and easy procedure to open the lamina terminalis during aneurysm surgery. With this maneuver, we could reduce the incidence of hydrocephalus after aneurysmal spontaneous SAH. Thus, it is considered that the opening lamina terminalis is one of the effective methods for preventing the development of hydrocephalus after aneurysmal spontaneous SAH.

  • Complications experienced during lymphatic surgery have not been ubiquitously reported, and little has been described regarding how to prevent them. We present a review of complications reported during the surgical management of lymphedema and our experience with technical considerations to reduce morbidity from lymphatic surgery. A comprehensive search across different databases was conducted through November 2020. Based on the complications identified, we discussed the best approach for reducing the incidence of complications during lymphatic surgery based on our experience. The most common complications reported following lymphovenous anastomosis were re-exploration of the anastomosis, venous reflux, and surgical site infection. The most common complications using groin vascularized lymph node transfer (VLNT), submental VLNT, lateral thoracic VLNT, and supraclavicular VLNT included delayed wound healing, seroma and hematoma formation, lymphatic fluid leakage, iatrogenic lymphedema, soft-tissue infection, venous congestion, marginal nerve pseudoparalysis, and partial flap loss. Regarding intra-abdominal lymph node flaps, incisional hernia, hematoma, lymphatic fluid leakage, and postoperative ileus were commonly reported. Following suction-assisted lipectomy, significant blood loss and transient paresthesia were frequently reported. The reported complications of excisional procedures included soft-tissue infections, seroma and hematoma formation, skin-graft loss, significant blood loss, and minor skin flap necrosis. Evidently, lymphedema continues to represent a challenging condition; however, thorough patient selection, compliance with physiotherapy, and an experienced surgeon with adequate understanding of the lymphatic system can help maximize the safety of lymphatic surgery.

  • Background: B-1 cells differ from conventional B-2 cells both phenotypically and functionally. The aim of this study was to investigate the difference between peritoneal B-1 cells and splenic B-2 cells in proliferation. Methods: We obtained sorted B-1 cells from peritoneal fluid and B-2 cells from spleens of mice. During the culture of these cells, immunoglobulin secreted into the culture supernatants was evaluated by enzymelinked immunosorbent assay. Entering of S phase in response to LPS-stimuli was measured by proliferative assay. Results: Spontaneous Immunoglobulin M production occurred in peritoneal B-1 cells but not in splenic B-2 cells. LPS stimulated peritoneal B-1 cells secreted IgM at day 1, but splenic B-2 cells at day 2. In thymidine incorporation, peritoneal B-1 cells entered actively S phase after 24hours LPS-stimulation but splenic B-2 cells entered actively S phase after 48 hours. Conclusion: IgM secretion and S phase entering occurred early in peritoneal B-1 cells compared to splenic B-2 cells.

  • 본 연구는 대구 국채보상운동기념 공원 일대를 대상으로 수목이 주변 흐름과 기온에 미치는 영향을 조사하였다. 이를 위하여, 전산유체역학(computational fluid dynamics, CFD) 모델에 수목의 항력 효과와 냉각 효과를 반영하였고 현장 측정 결과와 비교하였다. 기상 유입 경계 조건은 기상청 국지예보모델(local data assimilation and prediction system, LDAPS) 자료를 사용하였다. 수목 유무에 따른 대기 흐름과 기온 분포를 조사하기 위하여, 수목이 존재하는 현재 상태와 수목이 존재하지 않는다고 가정한 상황에 대하여 수치 실험을 수행하였다. 수목이 없는 경우, 공원 내부에서는 장애물 영향이 작아 강한 풍속과 단조로운 흐름이 형성되었다. 기온은 풍속에 반비례하여 풍속이 강한(약한) 지역에서는 낮게(높게) 모의되었다. 반면, 수목이 존재하는 경우, 수목 항력(냉각) 효과는 식재 밀도가 높은 공원 내부의 풍속(기온)을 40 (5)% 이상 감소시켰고 공원 외부 지역까지 영향을 미쳤다. 또한 공원 내부에는 매우 복잡한 흐름이 형성된다. 도로변 근처에서도 가로수에 의해 풍속과 기온이 전체적으로 감소하지만, 수목에 의한 흐름 패턴 변화로 인해 오히려 풍속과 기온이 증가하는 지역도 발생했다. 수목 냉각 효과에 의한 기온 감소는 주간에는 4-6%였지만, 야간에는 1% 미만으로 미비했다. 수목 항력 효과에 의한 풍속 감소는 주·야간 모두 40% 이상 크게 나타났다.
