A very rare case of multifocal eosinophilic granuloma without extraskeletal involvement in 35 year-old ma was experienced. The patient was admitted for the painful swelling of the right clavicular region and was treati with curettage and autograft of iliac bone. Five months later newly developed the pain in the trochanteric lesion left femur without fever, and also was confirmed as the same lesion. Both lesions were treated with curettage and iliac bone graft, and were followed by radiotheraphy. According to the pathological study, those lesions were confirmed as the multifocal eosinophilic granuloma.

One hundred and two patients with fracture of the tibial shaft were treated conservatively at the Department of Orthopaedic Surgery, National Medical Center from 1977 to 1982. In this article, we have analyzed early and late influencing factors upon healing process of the tibial shaft fractures treated with conservative methods. Early factors: Age, fracture type, initial displacement, comminution, open fracture, ipsilateral fibular fracture and associated injuries. Late factors: Interval between accident & final manipulation, distraction of fracture site after skeletal traction, and condition of final apposition. Also, we had the result that the mean healing time of tibial shaft fx. was 17.9 weeks by conservative treatment.

Perfluorodecalin, which is one of the perfluorocarbon liquids, is not established safety in use of long-acting intraocular tamponade. Therefore, to determine its safety we injected it alone and combined with silicone oil into the vitreous of vitrectomized eyes. We evaluated the changes of the fundus, electroretinogram, histopathology as light and electron microgragh after lensectomy and vitrectomy in pigmented rabbits periodically. In rabbits replaced with perfluorodecalin alone, fundus showed mild proliferative vitreoretinopathy and micrographs showed the destruction of the inner and outer segments of the photoreceptors. In rabbits replaced with perfluorodecalin and silicone oil, fundus showed more severe proliferative vitreoretinopathy than perfluorodecalin alone and micrographs showed the destruction of the entire retina. In electroretinogram, the amplitude was decreased markedly. So, it is considered that perfluorodecalin was not tolerant in case of longacting intraocular tamponade and also perfluorodecalin combined with silicone oil developed severe proliferative vitreoretinopathy.

Inspite of technical advances, the need for pharmacologic treatment of proliferative vitreoretinopathy was increased. In order to evaluate the antiproliferative effect of various antimetabolites to the rabbit retinal pigment epithelial cell, we treated cultured rabbit retinal pigment epithelial cell with different concentration of drugs to perform dose inhibition studies. We found that the antimetabolites inhibited the proliferation of rabbit retinal pigment epithelial cell in a dose dependent and a time dependent manner. The drug concentration required for 50% inhibition of cell growth (ID50) were found to be as follows (BCNU; 6.51 mg/L, 5-FU ; 8.94 mg/L, Daunorubicin; 0.03mg/L, Mitomycin-C; 0.26mg/L).

The lack of available cadaveric organs for transplantation has result in an increased number of kidney transplantation from living donors. In order to characterize correlation of variable factors which affect on the renal graft survival and to compare graft survival of living related donor with that of living unrelated donor, the 515 cases of renal transplantation between January 1979 and December 1997 were reviewed. Each effect of factors included recipient age, donor age, infection, acute rejection, tissue typing, type of donor on graft survival was analyzed as well as the interrelationship on graft survival between six risk factors. It was risk factors which effect on the graft survival that acute rejection, tissue typing and type of donor (P=0.00, P=0.001, P=0.00). The 1 and 5 year graft survival rates of cadaveric renal donor group and acute rejection positive group were 64.8-32.4%, 84.5-49.8% for younger recipient group (<30), 81.3-53.9%, 84.5-49.8% for ideal age group (30-49), 0-0%, 44-44% for older recipients group (>50) (0.017). The 1 and 5 year survival rate of cadaveric renal donor group was 42.8% and 28.6% during 1978-1983, 37.5% and 12.5% during 1984-1990 and 100% and 80% during 1991-1997. The grafts survival rate of unrelated living donor is significantly higher than that of cadaveric grafts during 1978-1990 and had a survival rate similar to that of living related donor grafts under all the circumstance given. The tissue typing, acute rejection and type of donor were significant factor which have influence on the graft survival. The cadaveric renal donor & acute rejection had significantly negative effect in older recipients (>50). Recently, the survival rate of cadaveric graft was remarkably increased, but in the future the more data collection for cadaveric graft is required. Living-unrelated renal transplantation provides comparable result to living-related renal transplantation and the unrelated living donor is excellent source of organs for renal transplant recipients.

8.A review of the designated health care institution for child abuse in Korea and the compatible systems in other countries
Pediatric Emergency Medicine Journal 2020;7(1):1-9
This article reviews the designated health care institution for child abuse in Korea and the compatible systems in other countries. The Korean system is ready to be commenced by a relevant law, which came into effect in July 2019. To find lessons for the designated hospital or professional system, we examined the designated institutions for rape victims, tuberculosis patients, and aftercare for emergency department-based suicide attempters. We also looked at safeguarding system of the United Kingdom, which comprises designated and named professionals, and the National Association of Children’s Hospitals and Related Institutions guidelines and specialist system in the United States. The systems in the United States and the United Kingdom may offer insight to improving the planned designated health care institution for child abuse in Korea. This includes policy issues such as qualification control of professionals, role differentiation in accordance with the hospital classification, and assigning the title of the professional and health care institutions.

A glomus tumor is an uncommon soft tissue tumor that is most commonly found in the subungual area and a glomus originating in the trachea is extremely rare. Histologically and ultrastructurally, these tumors have been divided into three subtypes: classic glomus tumors, glomangiomas, and glomangiomyomas. Glomangiomyomas account for less than 10% of all glomus tumors and are the least common type. We report a case of a 54-year-old man with glomangiomyoma of the trachea who presented with stridor. We treated the tumor by segmental resection and primary repair via a transcervical approach.

Pheochromocytoma with pregnancy is very uncommon but it is associated with very high maternal and fetal morbidity and mortality. Antepartum diagnosis and proper management can prevent mother and fetus from potentially lethal outcome. Since pheochromocytoma produces and secretes catecholamines, hemodynamic instability can be brought. The aim of anesthetic management is the avoidance of drugs and episodes that will result in hypertensive crisis, and the selection of safe anesthetic measures and anesthetics to mother and fetus. We report a case of pheochromocytoma with pregnancy managed with combined anesthetic technique-epidural anesthesia for cesarean section and general anesthesia for resection of pheochromocytoma 3 weeks after cesarean section. ?
