There have been so many methods described for the correction of the deviated noses but it is difficult to get satisfactory results and recurrence rate is high. There is no exact explanation why the recurrences are so high and no estabished guides for techniques according to the surgical pathology. We found the classical swinging door technique effective in cases where the caudal septum deviated from the midline. However, where the caudal septum and the tip stay in the midline, scoring or submucosal resection do not work well enough to cortet them. We used the reverse swinging door technique of our own. After elevation of mucoperichonodrium, we did sagittal section in the posterior septum and moved the septum to the midline on the pivot point of the caudal septum and. The gap created in the posterior portion of the septum were filed with bone grafts, cartilage grafts or Medopor, which were sutured to the septum, We did this technique with or without osteotmies in 56 deviated noses for last 5 years. The results were very satisfactory and there was no complication.

In shape and dimensions, the tibial plateaus are asymmetric with the larger medial tibial plateau and both have a posterior inclination with respect to the shaft of the tibia. Maximizing tibial coverage is an impotant consideration in total knee arthroplasty to provide stahility and load transfer and to improve long-term survival rate of the implants. Most tihial tray designs are symmetric, but several asymmetric designs are available. We evaluated the proximal tibial resection surface during total knee aithroplasty to delineate the tibial plateaus in korean. After tihial bone cut during 100 TKA procedures, the outline of tibial resection suiface was traced and rotational axis of true tibial component was marked intraoperatively. A line was drawn at the maximal anteroposterior (AP) diameter of lateral tibial condyle with parallel to rotational axis of component, and then a transverse axis was drawn at the midpoint of maximal AP diameter of 1ateral tibial condyle. Anteroposterior 10, 20, 30., 40% and midpoint from the media1 and lateral peripheries were calculated manually. The average AP medial 10, 20, 30 and 40% dimensions were 34.7, 43.8, 48.0 and 43.2mm, respectively. The average AP lateral 10, 20, 30 and 40% dimensions were 30.2, 38.4, 42.0 and 40.9mm, respectively. The ratio of medial/lateral AP dimensions 10, 20, 30 and 40% from periphery were 116.9, 114.7, 114.5 and 106.4%, respectively. From these data, we know the asymmetry of the proxirnal tibia1 plateaus in korean. We hope that rnore data will be ohtained in multicenter studies and it will help us to select tibia1 tray and to design the tibial component in korean. But, more accurate standard measures will he need to minimize an error of measurements.

The eosinophilia-myalgia syndrome associated with ingestion of L-tryptophan in man is defined by the CDC(1989) as follows: 1) eosinophil count more than 1,000 cells per microliter; 2) generalized myaligia(at some point during the course of illness) of severity sufficient to affect a patient's ability to pursue his or her usual daily activities; 3) no evidence of any infection(e.g., trichinosis) or neoplasm that would explain either the eosinophila or the myalgia. The pathologic findings of the eosinophilia-myalgia syndrome varies according to the degree of severity and types of inflammatory cells in the skeletal muscle. In order to simulate this syndrome in animals and further determine its histopathogenesis, L-tryptophan was administered to rats in the laboratory at various doses(25 mg/kg, 50 mg/kg, 150 mg/kg) over a set period of time. In this study, positive histopathologic findings were designated according to the inflammatory cell infiltration of the epimysium and epineurium. Most of the pathologic findings in the positive group were that of inflammatory cell infiltration composed mainly of eosinophils in the epimysial, epineurial connective and surrounding adipose tissues. Only a few necrotic muscle fibers were seen, and there was absence of any evidence of inflammatory cell inflitration in endoneurium or axonal degenerations. Of 59 rats which were given L-tryptophan, 27 rats(45.8%) met the criteria and were designated as belongintg to the positive group. Only 2 rats ingested with L-tryptophan(150 mg/kg) for 2 months and 4 months showed an eosinophil count more than 1,000 cells/microliter. The eosinophil count in the positive group showed significantly different levels when compared to the the negative group and control group. On the other hand, there were no significant differences in the electrodiagnostic study and serum CK, SGOT, SGPT level between the positive, negative and control groups. In summary, histopathologic findings similar to the eosinophilia-myalgia syndrome were inducible in rats followign the administration of L-tryptophan.

BACKGROUND: The pediatric CPR is rather uncommon practice than adult CPR in emergency room. Therefore, few interest and studies were focused in pediatric CPR. The object of this study is to make an analysis about pediatric CPR performed within hospital setting. METHOD: From January 1. 1990 to December 31. 1996, a total of 59 patients, less than 15-year-old, who received cardiopulmonary resuscitation were subject of this study. The study was done retrospective chart analysis for sex, age, weight, the place of cardiac arrest, initial EKG rhythms, endotracheal tube size, the causes of arrest, CPR time, ROSC, the amount and types of CPR drugs used during resuscitation. Wilcoxon rank sum test and chi2 test were used to compare the dose of drugs during CPR in each group. RESULTS: There were no statistical difference between ROSC and non-ROSC group in place of arrest, initial EKG rhythms, CPR time, dosage of CPR drugs. CONCLUSION: The uniform reporting guideline of pediatric advanced life support should be used for future pediatric CPR study, such as Utstein style guideline in pediatric CPR.

Journal of the Korean Surgical Society 2010;79(Suppl 1):S16-S25
PURPOSE: Although varicose veins are very common in adults, the mechanism of the disease has not been established. Degradation of the extracellular matrix is regulated by various matrix metallopreteinases (MMPs) and their inhibitors tissue inhibitor of metallaproteinase (TIMPs). This study was performed to analyse the relationship between venous wall degeneration and expression of these matrix proteinases. METHODS: Twelve great saphenous vein (GSV) segments from 7 patients without varicose veins (control) and 86 GSV segments from 18 patients (22 limbs) with varicose veins (C2,4,5EPASPR) were used for this study. Light microscopic examination was used in the evaluation of vein wall degeneration, immunohistochemistry and Western blotting for the expression of MMPs (MMP-1, MMP-2, MMP-9 and MMP-13) and TIMPs (TIMP-1 and TIMP-2), and zymography for gelatinolytic activity of MMP-2 and MMP-9 were performed. RESULTS: MMP-9 was more strongly expressed in the vein wall of both control and patient groups, especially in the endothelial cells and medial muscle layers and TIMP-2 followed. The expression of MMP-9 was closely related to the degree of venous wall degeneration. Activated MMP-2 and MMP-9 were observed in both groups and expressed more in the proximal GSV of the patients. In the Western blotting, the expression of MMP-9 and TIMP-1 were significantly higher than other MMPs and TIMP-2 in the patients with varicose veins. CONCLUSION: MMP-9 is much more expressed in the wall of degenerative veins. This matrix-degrading enzyme may play an important role in the degeneration of venous wall followed by its remodeling.

The present study is aimed to investigate the clinical and pathologic features of GI lymphomas and the immunocytochemical characteristics, using 71 cases of primary GI lymphomas examined at the Department of Pathology, Yonsei University College of Medicine, Youngdong Serverance Hospital and Yonsei University Wonju College of Medicine from January, 1976 to December, 1985. Results obtained were as follows: 1) Sixty eight cases were Non-Hodgkin's lymphoma and 3 Hodgkin's lymphoma. Surgical resection was done in 58 patients and surgical biopsy in 13. 2) The primary sites of the tumors were stomach, small intestine, ileocecal area and large intestine in a descending order of frequency. 3) The mean age at the time of diagnosis was 45 years. The tumor of the small intestine was generally detected in the younger age and that of the large intestine in the older age. The overall male to female ratio was 1.9 : 1. 4) Abdominal pain was the most common presenting symptom irrespective of the sites of the tumor. Duration of the symptoms were evenly distributed from hours to 12 monthes. 5) The size of the tumors was less than 10 cm in the largest dimension in most of the cases (79.3%). The gross types of the GI lymphomas were ulcerative (27.6%), polypoid (20.7%), multinodulated (17.2%) and diffuse thickening. The rate of lymph node involvement was 44.4% in tumors confined to the serosa, while 82.6% in tumors with serosal penetrations. 6) Classification of 68 cases of Non-Hodgkin's lymphoma according to Working Formulation revealed 50 cases of intermediate grade, 13 cases of high grade and 5 cases of low grade. According to Rappaport classification, all were diffuse types, among which diffuse histiocytic type was the most common. According to Lukes-Collins classification, 60 cases were B cell types, 4 cases genuine histiocytes types and 3 cases T cell types. Most of the gastric and intestinal lymphomas belonged to the follicular center cell (small and large cleaved, large cleaved) types. 7) Immunoperoxidase stains were done in 55 cases of malignant lymphomas. Thirty (65.9%) of 47 B cell lymphomas revealed a positivity for B cell markers. Twenty three (48.9%) of them showed a monoclonality, in which kappa/IgG pattern was most frequently demonstrated. Four cases of true histiocytic lymphomas were positive for alpha-1-antichymotrypsin and lysozyme, the former of which was seemed to be a more sensitive marker for histiocytic differentiation. An attempt was made to evaluate the significance of the degree of reactive histiocytic infiltrates within the lymphoma in relation to the progosis, but correlation could not be made because of the limited cases.

BACKGROUND: Ciclopiroxole.minsolution or cream is the topical in imycotic agent which has been known to have the ability to penetrate the horny skin and nail keratin. OBJECTIVES: The purpose of this study was to evaluate the pierapeutic effect of 1% ciclopiroxolamine solution on onychomycosis. METHODS: 1% ciclopiroxolamie solution was applied topically to hentire surface of t,he diseased nail at least twice a day for 12 to 36 weeks according to the verity of nail involvement and degree of improvement in 21 cases of onychomycoses. RESULTS: 1. With only topical application of 1% ciclopiroxolamine solutior, 4 out of 21 cases(67%) showed 25% or more reduction of the affected nail area, and 8 out of 21 cases(38%) showed 50% or more reduction of the affected nail area. 2. There was no significant difference in the degree of improvem of according to the duration of disease. 3. Therapeutic effect was relat.ively high on Candida albicans, while it was relatively low on Aspergillus species. 4. 3 out of 7 cases of mild(up to 30%) involvement showed a 7% or more reduction of the affected nail, while 4 out of 6 cases of severe(60-100%) involvement showed a 25% or less reduction of the affected nail. 5. As side effects during the topical application of 1% ciclopiroxol nr ne solution, periungualer ythema appeared in 3 cases, and a burning sensation in 4 of 21 cases. CONCLUSION: 1% ciclopiroir olaniine solution could be tried as an effctive therapeutic agent on onychomycosis for the patient who would not be tolerable to oral an ifiigal medication for associated systemic diseases or who does not want oral medication.
