In 1910 Purtscher first presented his original report of "angiopathia retinae traumatica" before the German Congress of Ophthalmology in Heidelberg. Since then many varying fundus pictures have been described as "Purtscher's Disease" and many theories have been advanced as to the cause. In 1962 Marr and Marr provided an extensive review of the literature on traumatie retniopathy and pointed out that the cause of Purtscher's retinopathy was an abrupt rise of intravascular pressure in the vessel entering and leaving the orbit, and in most cases the mechanism of the injury was a sudden and violent compression of the chest. Recently we have experienced a case of bilateral Purtscher's traumatic retinal angiopathy leading to optic nerve atrophy and macular degeneraion. Our patient is a 36-year-old previously healthy Korean male. who had his left chest compressed by a truck when he was working in the country farm. Just after the accident he fall into an unconscious state for a short time. Two days after admission he was referred to our ophthalmologic department because of visual impairment. Funduscopic examination revealed Purtscher's retinopathy in both eyes. His chest X-ray examination showed several fractured ribs anterolaterally. Within several days after the accident the whitish retinal exudates and hemorrhages gradually disappeared in the left ocular fundus, but in the right fundus the retinal edema, situated at posterior pole, persisted for about 7 months duration. During this period optic nerve atrophy developed ill the right fundus. As soon as the retinal edema subsided, retinal degeneration of the macular area appeared in the right fundus. Five months after the accident temporal optic nerve atrophy appeared and the patient complained of marked visual impairment in the left eye. We could not find any similar cases in the literature, that is, after the retinopathy and impaired vision recovered, later, the vision was markedly impaired again due to secondary optic nerve atrophy and development of macular Degeneration. In a survey of literature we want to say that the pathogenesis of Purtscher's traumatic retinal angiopathy is due mainly to the result of a sudden and severe increased intravascular pressure. particularly in the upper portion of body. Following points influenced our thought. 1. The ocular fundus changes similar with Purtscher's retinopathy could be seen in hydrostatic pressure syndrome and compression cyanosis syndrome. 2. Purtscher's retinopathy could developed in minor chest compression which is not strong enough to fracture ribs or other banes. 3. Usually Purtscher's retinopathy is developed in both eyes. If unilateral development occurs, it is almost on the right eye. If bilaterally the right eye is more severe than the left. This is postulated due to the shorter venous path to the rijsht eye. In addition, the prognosis of Purtscher's retinopathy seems to be good but poor result such as in our case and other previously reported cases are also possible.

A survey of the literature on the treatment of ruptures of deltoid ligament associated with fracture of distal part of fibula is controversial. Some authors advocated surgical repair of the ruptured deltoid ligament based on the theoretical consideration, while others advocated non-operative treatment based on the clinical consideration. We studied the results in forty-five patients who were treated for disruption of the deltoid ligament and a distal fibular fracture. The length of follow-up in our series was twelve to twenty-four months, with an average of fifteen months. When the fibular fracture was adequately reduced and medial clear space was returned to its normal width, the 91 percents both of patients of being treated with repair of deltoid ligament and patients of being treated without repair had a good or excellent results.

BACKGROUND AND OBJECTIVES: We investigated in patients with coronary vasospastic angina whether the exercise ECG test results are influenced by the different modes of exercise load and compared the clinical characteristics including coronary risk factors between patients with positive and negative exercise tests. MATERIALS AND METHODS: This study comprised 34 patients with documented coronary artery spasm without significant stenosis (coronary artery luminal diameter narrowing <70%) and treadmill exercise test. Treadmill exercise ECG test was performed based on Bruce's protocol (graded exercise test, GET) and sudden rapid exercise protocol (non-graded exercise test, NGET) in the morning of the same day. RESULTS: 1) Of 29 patients who underwent both GET and NGET, 19 patients manifested positive result by NGET, whereas only 11 patients did by GET (66 vs. 38%, P=0.04). All patients with positive GET had positive NGET and 8 of 18 patients with negative GET had positive NGET. 2) Of 34 patients who underwent GET, there was no significant difference in frequency of hypertension, diabetes, current smoking, presence of effort chest pain by history, mixed disease (fixed stenosis >50%, <70% of luminal diameter) or total cholesterol level between patients with positive and negative results. In 18 typical variant angina patients by clinical history, 8 of 10 patients with high disease activity (5 times or more attack per week) manifested positive result by GET or NGET, whereas 4 of 8 patients with low disease activity (80 vs. 50%, P=NS). CONCLUSION: In patients with coronary vasospastic angina, sudden rapid exercise could induce more frequently coronary artery spasm than multistage exercise. The result of an exercise test may not be correlated with coronary risk factors, coronary anatomy, effort chest pain, and the disease activity.

PURPOSE: This study was performed to evaluate the cosmetic outcome of conservative treatment for early breast cancer and to analyze the factors influencing cosmetic outcome. MATERIALS AND METHODS: From February 1992 through January 1997, 120 patients with early breast cancer were treated with conservative surgery and postoperative radiotherapy. The types of conservative surgery were quadrantectomy and axillary node dissection for 108 patients (90%) and lumpectomy or excisional biopsy for 10 patients (8.3%). Forty six patients (38%) received adjuvant chemotherapy (CMF or CAF). Cosmetic result evaluation was carried out between 16 and 74 months (median, 33 months) after surgery. The cosmetic results were classified into four categories, i.e., excellent, good, fair, and poor. The appearances of the patients' breasts were also analyzed for symmetry using the differences in distances from the sternal notch to right and left nipples. A logistic regression analysis was performed to identify independent variables influencing the cosmetic outcome. RESULTS: Cosmetic score was excellent or good in 76% (91/120), fair in 19% (23/120) and poor in 5% (6/ 120) of the patients. Univariate analysis showed that tumor size (T1 versus T2) (p=0.04), axillary node status (N0 versus N1) (p=0.0002), extent of surgery (quadrantectomy versus lumpectomy or excisional biopsy) (p=0.02), axillary node irradiation (p=0.0005) and chemotherapy (p=0.0001) affected cosmetic score. Multivariate analysis revealed that extent of surgery (p=0.04) and chemotherapy (p=0.0002) were significant factors. For breast symmetry, univariate analysis confirmed exactly the same factors as above. Multivariate analysis revealed that tumor size (p=0.003) and lymph node status (p=0.007) affected breast symmetry. CONCLUSION: Conservative surgery and postoperative radiotherapy resulted in excellent or good cosmetic outcome in a large portion of the patients. Better cosmetic results were achieved generally in the group of patients with smaller tumor size, without axillary node metastasis and treated with less extensive surgery without chemotherapy.

In addition to identifying genetic differences between target populations, it is also important to determine the impact of genetic differences with regard to the respective target populations. In recent years, there has been an increasing number of cases where this approach is needed, and thus various statistical methods must be considered. In this study, genetic data from populations of Southeast and Southwest Asia were collected, and several statistical approaches were evaluated on the Y-chromosome short tandem repeat data. In order to develop a more accurate and practical classification model, we applied gradient boosting and ensemble techniques. To infer between the Southeast and Southwest Asian populations, the overall performance of the classification models was better than that of the decision trees and regression models used in the past. In conclusion, this study suggests that additional statistical approaches, such as data mining techniques, could provide more useful interpretations for forensic analyses. These trials are expected to be the basis for further studies extending from target regions to the entire continent of Asia as well as the use of additional genes such as mitochondrial genes.

Tissue array contains hundreds or thousands tissues from different cases, and has been known useful for rapid analysis of markers in a large numbered work. This has mainly been used in investigative purpose, and few has been reported for diagnostic trial. Diagnosis of early myocardial infarction is important in medicolegal field. Immunohistochemical staining using various antibodies has become a popular tool for this purpose, but standardization and reproducibility have been problems. Use of tissue array is promising in this points. We have made two cardiac tissue arrays using 87 different cases and have verified the feasibility of tissue array in forensic field. Experiences and several issues concerning tissue array are discussed.

There are a considerable number of reports suggesting a common pathogenesis of IgA nephritis(IgAN) and Henoch-Sch nlein purpura(HSP). In previous reports, a patient develops IgAN after kidney transplantation for HSP nephritis, one of Identical twin boys, developed IgAN and the other HSP, and a boy with IgAN later developed HSP. We report two cases, one with IgAN who later developed HSP and the other with HSP who later developed IgAN, suggesting that IgAN and HSP have a common pathogenesis.

PURPOSE: To evaluate the usefulness of internal fixation with plate in treating infected nonunion of long bone. MATERIALS AND METHODS: From March 1993 to February 2004, ten patients who underwent internal fixation with plate and cancellous bone graft on account of infected nonunion of long bone were retrospectively examined. The medical treatment were composed of thorough and adequate debridement of necrotic tissue, irrigation and plate fixation. Two patients were operated on with bridging plate method. Autologous cancellous bone graft was performed in 6 patients. In 2 cases, it was performed 4 weeks after internal fixation. RESULTS: In 9 patients, radiographic union appeared on the average of 6.8months and infections were cured before union occurred. CONCLUSION: Internal fixation with plate is a useful method for the solid fixation in the treatment of infected nonunion. The general concern was that the inserted hardware worsened the infection, which was overcomed with the operative techniques as bridging plate, debridement and cancellous bone graft.
