INTRODUCTION: There are three anatomic findings that correlate with a patient risk for developing anterior acromial impingement : acromial shape, anterior downsloping of the acromion. To analyze the effect of anterior and lateral downslopings and subacromial interval to the impingement syndrome retrospectively, the authors reviewed 32 patients who performed MRI of the shoulder joint in the Dankook university hoipital. MATERIALS AND METHODS: Eighteen males & fourteen females were reviewed and the average age was 46.6 years old. There were 23 cases of impingement syndrome and 9 cases of control group. The authors analyzed oblique coronal images and oblique sagittal images in shoulder MRI.

PURPOSE: Infant leukemia is rare and accounts for 5% of leukemia in children. It differs from childhood leukemia in biologic and clinical features and has a poor prognosis. Research on infant leukemia is difficult due to the scarcity of cases. We studied the clinical progress and prognosis of infant leukemia diagnosed in our hospital, in order to contribute to the treatment and prognosis of infant leukemia. METHODS: The patients who were diagnosed with leukemia in the first 12 months of life were analysed between January 1991 and December 2000 in Yonsei Medical Center. We analysed the sex, age, clinical features, treatment outcome, prognostic factor, and survival rate. RESULTS: Among a total of 41 cases, 19 cases were diagnosed with acute lymphoblastic leukemia (ALL), 15 cases with acute myelogenous leukemia (AML), 2 cases with chronic myelogenous leukemia (CML), and 5 cases were unclassifed. Twenty-two were males and 19 females; age at diagnosis was 4 months in ALL, 8 months in AML, and 4 months in CML. Common clinical features at diagnosis were pale appearance and fever, others were poor oral intake, abdominal distension, and irritability. Hyperleukocytosis with average over 20,000/mm3, anemia, and thrombocytopenia were seen. By immunologic surface marker analysis, 8 of 15 B-lineage ALL were CALLA negative, early pre-B ALL. The remission induction rate was 79% in ALL and 60% in AML. The 5 year-survival rate of 41 patients was 29.2%. Sex, age at diagnosis, white blood cell count > 50 109/L, hepatomegaly, and CNS involvement were not prognostic factors. CONCLUSION: Infant leukemia differs from childhood leukemia in biological and clinical features and has a poor prognosis. Therefore, further clinical research is needed to improve the outcome of infant leukemia.

PURPOSE: The purpose of this study was to measure the strains of normal and lax anterior cruciate ligament (ACL) under serial loading using specially designed ACL strain analyzer (ASA) during arthroscopic examination. MATERIALS AND METHODS: The study is based on sixty-eight patients. Before the arthroscopic examination, all cases were divided into three groups according to their laxity based on Lachman test, KT2000 arthrometer, and magnetic resonance imaging. During arthroscopic examination, the ASA was connected with ACL using anteromedial portal with the knee flexed in 90. Under serial loading to ACL, the strains were illustrated and calculated. RESULTS: A statistically significant differences had been shown in strains between normal and lax ACL. Using ANOVA test, the ASA results according to preoperatively divided groups showed no significant differences between all groups and each loads. CONCLUSION: We had designed newly diagnostic method for estimate of ACL laxity, and measured the strains of lax ACL compared with normal ACL. This diagnostic method will be helpful to establish treatment plan for injuried ACL during arthroscopic examination.

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.
