PURPOSE: To determine the relation between clinical results and correction angle in proximal tibial osteotomy through the retrospective study. MATERIALS AND METHODS: Seventy-two valgus osteotomies of the tibia were performed in forty-nine patients from 1985 to 1992; average follow-up period was 7 year 11 months(range, 5 to 12 years). We classi- fied the patients into three groups according to the tibiofemoral angle measured at the last follow-up. Group I includes patients with less than valgus 6 degrees of tibiofemoral angle, Group II with from valgus 7 degrees to 9 degrees and Group III with more than valgus 10 degrees. RESULTS: The Insalls Hospital for Special Surgery knee score was gradually decreased in time as 95 at postoperative 2 years, 92 at 5 years and 82 at the last follow-up. The average preoperative tibiofemoral angle was varus 3.4 degrees and the average postoperative tibiofemoral angle was corrected as valgus 8.0 degrees, 7.9 degrees at two years, valgus 7.0 degrees at five years and valgus 5.4 degrees at the last follow-up. The group I, 40 cases(mean 9 year 7 month follow-up), showed postoperative valgus 6.4(3-15) degrees and val- gus 2.6 degrees at the last follow-up. Loss of correction was 3.8 degrees and knee score was 76 at the last fol- low-up. The group II, 21 cases(8 year 1 month), showed postoperative valgus 9.0(7-11) degrees and 7.6 degrees at the last follow-up. Loss of correction was 1.4 degrees and knee score was 83.5 at the last follow- up. The group III, 11 cases(7 year 7 month) showed postoperative valgus 11.4(10-15) degrees and 10.9 degrees at the last follow-up. Loss of correction was 0.5 degrees and knee score was 97 at the last follow-up. The group III showed better maintenance of postoperative correction angle and clinical results than the other gf OUpS. CONCLUSION: Deductively, it is essential to correct tibiofemoral angle more than 7, especially ranged from 10 to 15 degrees for the best long-term clinical results.

Screw fixation of the tibial component offers advantages in initial fixation in cementless total knee replacement. But the high incidence of screw related osteolysis was reported. The purpose of this study is to evaluate clinical results of cementless total knee replacement and to look for radiographic changes at the screw-bone interface. From January 1988 to December 1991, primary cementless total knee replacements with Miller Galante I (Zimmer, Warsaw. IN) were performed to 53 knees at Kyung Hee university hospital. Among them, 21 cases which could be followed-up for more than 4 years were studied retrospectively about the clinical and radiographic results. The mean follow-up period was 5.5 years(ranged from 4.2 years to 8 years). At the last follow-up period, knee scores of Hospital for Special Surgery were improved from mean 56 points to 90 points and the range of motion from 72 degrees to 110 degrees. In the last follow-up radiographs, osteolysis around screw was classified as linear(type I ), cystic(type II ) and cavitary(type III ) according to the width of the lucency around screws. Among 21 cases, radiographic findings of osteolysis around screw were detected in 10 cases but not in 11 cases. But clinical results were similar between these two groups. Among the total 84 screws(4 screws in each case), 21 screws(25%) showed screw related osteolysis typed as I in 13 screws(15.4%), II in 4 screws(4.8%) and III in 4 screws(4.8%). Among the 13 cases that followed-up more than 6 years, 20 screws(38%) showed screw related osteolysis typed as in 11 screws(21.2%), I in 5 screws(9.6%) and II in 4 screws(7.8%). The most frequently involved site of screw was anteromedial(33.3%). In conclusion, after mean 5.5 year follow-up, the clinical results were satisfactory but the development of osteolysis around screw might be an indicator of the implant failure.

PURPOSE: To analyze the clinical results of treatment for infected TKA and find a reasonable method of treatment. MATERIALS AND METHODS: Between March 1988 and August 1997, 34 patients with infection after total knee arthroplasty were treated at Kyung Hee University Hospital. The average follow-up period was 4 year 8 months. At-the time of infection management, the average age was 59 years (range, 20 to 79 years); there were 31 women and three men. Infected patients were managed with several methods. Twenty patients were treated with one-stage or two-stage reimplantation, and arthrodesis was done in 12 cases. Two cases were treated conservatively. We assessed knee function before and after revision, according to the knee rating system of The Hospital for Special Surgery. RESULTS: Prior to revision operation, the average knee score in 20 reimplantation cases was 52 points, and the average range of motion was 76. After revision, the average knee score was 84 points, and the average range of motion was 90. All patients had complete union at an average 5.3 months after arthrodesis. There were no recurrences of infection after one-stage or two-stage reimplantation, or fusion. CONCLUSIONS: Thoughtful method of treatment should be decided in managing infected total knee arthroplasty.

Globally, there have been a small number of donor cell leukemia cases reported but, to our knowledge, none have been reported in Korea until now. Donor cell leukemia is a rare though well-recognized complication that occurs after allogenic hematopoietic stem cell transplantation (allo-HSCT). Herein, we report the case of an 18-year-old woman who developed acute lymphoblastic leukemia originating from donor cells after allo-HSCT.

Objectives: ：In this study, elderly hospitalized patients aged 65 years or older who were admitted to a university hospital and referred to the department of psychiatry were classified into youngest-old, middle-old, and oldest-old. It was conducted to find out what factors contribute to the agitation pattern by age group, wheth-er there is a difference in the factors, and whether there is a difference in the severity of the agitation pattern. Methods: ：From July 1, 2021 to December 31, 2021, the medical records of patients aged 65 years or older who were referred to the department of psychiatry were retrospectively reviewed. Age, gender, route of hospitalization, department of referral, reason for referral, treatment method, presence of internal and surgical diseases, and hematological test data were investigated. Results: ：There was a significant correlation with the RASS score in cases of surgery referral and high CRP levels for youngest-old aged 65 to 74 years, in cases of surgery referral, dementia and hyponatremia for middleold aged 75 to 84 years, in case of dementia for oldest-old aged 85 years old or older. In addition, there were differences in the severity of agitation patterns between age groups. Conclusions ：As the age group increases, the agitation of delirium patients becomes more severe, and vari-ous factors contributing to the agitation pattern also differ by age group. Therefore, when treating elderly pa-tients with delirium, attention should be paid to factors that may affect agitation depending on age.

PURPOSE: Neutropenia is common in patients receiving myelotoxic chemotherapy. The aim of this study is to compare the efficacy, safety and adverse events between prophylactically administered Leukokine and Grasin. METHODS: An open-label, randomized, phase III study was designed to compare the effects of a subcutaneous injection of Leukokine (CJ Corp.) 100mug/m2 with Grasin (Jeil Pharm. Inc.) in patients receiving induction chemotherapy for acute leukemia. All patients received one dose of G-CSF every day during the study period. Total period of G-CSF injection was not over 14 days. The administration of G-CSF began on day 14 after beginning of chemotherapy under CCG strategy. In other chemotherapies, the injection of G-CSF started on day 1 from end of chemotherapy. Injection of G-CSF stopped after absolute neutrophil count recovery was achieved. RESULTS: The median numbers of times of administration were 9.6 (2~14) /cycle for Leukokine and 8.8 (2~14) /cycle for Grasin. The time to needed for neutrophil recovery more than 1, 000/mm3 was 6.6 4.9 day and 4.7 4.8 day of the Leukokine and Grasin, respectively (P=0.14). The mean duration of neutropenia less than 500/mm3 was 7.6 5.6 days for Leukokine and 6.1 6.0 days for Grasin (P=0.28). The results for the two groups were also not significantly different in adverse events, physical examination and laboratory findings. CONCLUSION: Leukokine was safe and well tolerated in these patients population. Injection of Leukokine provided neutrophil recovery with safety and efficacy similar to that provided by Grasin.

BACKGROUND: 'Eight drugs in a day' was one of the widely used regimen in medulloblastoma. Result of treatment of this regimen and comparison between pre-RT chemotherapy and post-RT chemotherapy were presented. METHODS: Medical records of children who were diagnosed as medulloblastoma and treated with 8 in 1 therapy in Seoul National University Children's Hospital from January 1986 to June 1997 were reviewed. RESULTS: 1) Forty nine cases(male: 30, female: 19) were analyzed. The age at diagnosis was between 3 months and 15 years 3 months and median age was 7 years 10 months. 2) The T stage by Chang classification revealed T1(2%), T2(26%), T3a(9%), T3b(56%), and T4(7%) in 43 cases. M stage revealed M0(46%), M1(15%), M3(37%), and M4(2%) in 41 cases. The surgical results revealed gross total resection(36%), near total resection(18%), subtotal resection(38%), and partial resection(9%). 3) The 5-yr disease free survival(DFS) rate of all tumors was 53%. There was no difference in DFS about sex, age, pathology, T stage, M stage, and surgical result. 4) Difference of 5-year DFS between pre-RT chemotherapy group(53%) and post-RT chemotherapy group(83%) was significant[-2Log(LR), P=0.023], excluding the patient relapsed or too young(below 18 month, who had more chemotherapy to delay radiation) to be received radiation therapy. CONCLUSIONS: DFS in post-RT chemotherapy was better than pre-RT chemotherapy. As medulloblastoma has the property to confine in CNS system, prior treatment with radiation as a intensive local therapy may be more effective than the systemic chemotherapy. Progression or relapse were the main causes of treatment failure. Result of treatment may be improved by more intensive therapy.

Scanning with whole-body 131I scintigraphy after surgery has been a valuable diagnostic modality in the surveillance of patients with differentiated thyroid cancer. Radioiodine uptake is rarely observed in non-lactating breast tissue, which mimics thyroid cancer metastasis. We now report a case of a 45-year-old female thyroid cancer patient who underwent radioiodine therapy, and in whom breast uptake of radioiodine was observed on a post-therapy whole body scan. Her serum prolactin level was elevated to 328 ng/mL at the time of the radioiodine uptake, and the hyperprolactinemia was induced by her antipsychotic medications. Six months after she discontinued that medication, her serum prolactin level was normalized to 12.6 ng/mL and breast uptake of iodine was no longer present in a follow-up whole body scan.

Previous studies have shown that hematopoietic stem cell transplantation (HSCT) may result in growth impairment. The purpose of this study was to evaluate the growth during 5 yr after HSCT and to determine factors that influence final adult height (FAH). We retrospectively reviewed the medical records of acute myeloid leukemia (AML) patients who received HSCT. Among a total of 37 eligible patients, we selected 24 patients who began puberty at 5 yr after HSCT (Group 1) and 19 patients who reached FAH without relapse (Group 2). In Group 1, with younger age at HSCT, sex, steroid treatment, hypogonadism and hypothyroidism were not significantly associated with growth impairment 5 yr after HSCT. History of radiotherapy (RT) significantly impaired the 5 yr growth after HSCT. Chronic graft-versus-host disease (cGVHD) only temporarily impaired growth after HSCT. In Group 2, with younger age at HSCT, steroid treatment and hypogonadism did not significantly reduce FAH. History of RT significantly reduced FAH. Growth impairment after HSCT may occur in AML patients, but in patients without a history of RT, growth impairment seemed to be temporary and was mitigated by catch-up growth.
