The t(3;21) (q26;q22) is associated with chronic myelogenous leukemia in blast crisis, leukemia evolving from therapy-related myelodysplasia, and with leukemia following other hematopoietic proliferative diseases. The t(3;21) is rare secondary aberration in blast crisis of Philadelphia(Ph)-positive chronic myeloid leukemia, which may be restricted to patients entering myeloid blast crisis. We report here in one case of chronic myeloid leukemia in blast crisis which reveals both t(9;22) (q34;q11), and t(3;21) (q26 ;q22). A 62-year-old male was diagnosed as chronic myeloid leukemia 5 years ago, received hydroxyurea therapy, and admitted because of gingival bleeding and fever. On examination, splenomegaly and leukocytosis with proliferated blasts(91%) in peripheral blood were noted. Bone marrow aspirate showed hypercellularity with severe blast proliferation(92.5%) which revealed all negative in peroxidase and PAS stain. Cytogenetic study of bone marrow cells showed the karyotype 46, XY, t(3;21) (q26;q22), t(9;22) (q34;q11), which might be suspected as myeloid blast crisis. Above finding was confirmed by the result of immunophenotyping(CD13 43.6%, CD34 68.2%, HLA-DR 91.6%). He received intensive chemotherapy, but still sustained proliferation of blasts was noted . The follow up cytogenetic study was as follows: 46, XY, 4(3;21) (q26:22), t(9;22) (q34;q11)/46, XY, t(3;21)(q26;q22), del(8) (q22), t(9:22) (q34,q11)/46, XY (16/3/1). He died soon from severe pancytopenia and sepsis.

Silicone gel breast implants may induce local(fibrous capsular contracture) or systemic(rheumatoid arthritis, systemic sclerosis, etc) complications. The exact mechanism of fibrous capsular contracture has not been fully understood. In the present study, we tried to find out the effect of silicone gel on the fibroblast proliferation which has been known as a major contributing factor in fibrous capsular contracture formation. In vitro, activated macrophages are known to secrete monokines which affect fibroblast proliferation and collagen synthesis. And tumour necrosis factor-alpha(TNF-alpha) and interleukin-6(IL-6), which were released by macrophages, were reported as potent stimulator of fibroblast proliferation. The goal of this study is to investigate the role of macrophages and tumour necrosis factor-alphaor interleukin-6 in the interaction of fibroblasts and silicone gel. We designed four groups, two experimental and two control, using Institute for Cancer Research(ICR) mouse peritioneal macrophage and silicone gel. For the preparation of the conditioned medium of macrophages, peritoneal macrophages were prepared and cultured for 24 hours on the silicone gel-coated and naked (not coated) surface [silicone gel-macrophage conditioned medium(SCM; experimental group) and normal polystyrene-macrophage conditioned medium(NCM; control group) respectively]. To correct the effect of 10% fetal bovine serum which was included in Rapid Prototyping and Manufacturing Institute (RPMI) 1640 medium and draw the effect only by macrophages, the RPMI 1640 medium with 10% fetal bovine serum was cultured by the same method on the silicone gel-coated and naked surface (silicone gel-macrophage free conditioned medium; SFM and normal polystyrene-macrophage free conditioned medium; NFM respectively). Each conditioned medium was added onto NIH 3T3 fibroblasts culture at a final 25% concentration of total culture medium and followed by the cultivation for 24 hours. For antibody neutralizing experiments, each conditioned medium was preincubated with polyclonal rabbit anti-mouse TNF-alpha antibody or polyclonal rat anti-mouse IL-6 antibody for 1 hour and then, conditioned medium with antibody was added to the culture medium of NIH 3T3 fibroblasts by the same method. After 24 hours cultivation, total number of viable fibroblast(cell growth), DNA synthesis and collagen synthesis of fibroblasts with each medium were measured by sulforhodamine B(SRB) assay, 3H-thymidine and 3H-proline incorporation respectively. The results were as follows: 1. In the experiment about the effect of the conditioned medium on the fibroblast activity, the experimental group(SCM), compared with the control group(NCM), showed a significant increase of the cell growth (p<0.01), a significant decrease of DNA synthesis(p<0.001), but no significant difference in the collagen synthesis. 2. In the experiment about the effect of polyclonal rabbit anti-mouse TNF-alpha antibody on the fibroblast activity, after the addition of antibody the experimental group, compared with the control group, showed a significant decrease of the cell growth(p<0.001), a significant increase of DNA synthesis(p<0.01), but no significant difference in the collagen syn thesis. 3. In the experiment about the effect of polyclonal rat anti-mouse IL-6 antibody on the fibroblast activity, after the addition of antibody the experimental group, compared with the control group, showed a significant decrease of the cell growth(p<0.001), a significant increase of DNA synthesis(p<0.0001), but no significant difference in the collagen synthesis. In conclusion, culture supernatants (conditioned medium) of peritoneal macrophages, activated by silicone gel, stimulate the NIH 3T3 fibroblast proliferation. TNF-alpha and IL-6, products of macrophage, are involved in the stimulation of NIH 3T3 fibroblast proliferation in an in vitro condition.

Congenital dislocation of the knee is very rare skeletal deformity and was firstly described by Chatelaine in 1822. Since then there have been a few number of case reports and some series discussing the etiology and treatment. The tibia is displaced anteriorly in relation to the femur. It is generally subdassified as simple hyperextention, subluxation, and dislocation depending on the degree of the joint displacement and the severity of disease. Early gentle manipulation and serial splintage or plaster cast are recommended for treatment and were successful in the majority except the case of quadriceps contrarture or late correction. The authors experienced one case of congenital dislocation of the right knee and brief review of the related literatures was made.

This is a comparative study based on the data of legal autopsies performed at the National Institute of Scientific Investigation, Seoul, during the year of 2000. In South Korea, the pathologists usually do not attend the death scene, and the scene investigation is performed only by the law enforcement agency. The latter collects the information needed for clarifying the cause and manner of death. The authors tried to estimate the efficiency of the death investigation through the discrepancy between the presumed and the most possible cause of death. We presumed the cause of death on the ground of police investigation and external examination by the general physicians, The most possible cause of death means the best diagnosis after autopsy by pathologists, with the consideration of police information. Followings are the summary of the results. The coincidence rate with the most possible death are over 90% in presumed trauma, asphyxia, thermal injuries, electrocution, starvation/neglect, and over 80% in drowning and natural deaths. The rate was low in medical injuries(26.6%) and poisoning(67.2%). 7.3 to 8.2% were natural in presumed blunt trauma, traffic injury and fall down injuries. Among 48 cases of presumed ligature strangulation, 6 were other type of asphyxia or other injuries, and 2 unknown. The coincidence rate was only 30.8% in acute alcohol poisoning. 5.9% of presumed fire death was proved other type of violent injuries. In the field of medical practices, only 6.3% of accused general medical procedures were proved dead due to themselves. But the rate was increased up to 49.0% in presumed surgery/anesthetic deaths. 12.9% were violent death in presumed natural death, and 64.6% were dead due to violent causes in the cases of no presumable cause of death.

Spinal dural arteriovenous fistulas are rare abnormal connections of artery and vein within the dura, at the level of the intervertebral foramen. A 57-year-old male developed weakness in both lower extremities and sphincteric dysfunction, which had stepwisely, progressive and fluctuating course since 6 months ago. He showed areflexia in both ankle & right knee. T-spine MRI showed high signal intensity with ill defined margin in T2WI and intensely enhanced by con-trast agent through lower thoracic and lumbosacral spinal cord. Selective spinal angiography revealed a dural arteriove-nous fistula with a nidus at thoracolumbar vertebral level, supplied by the internal iliac artery and enlarged medullary veins. Superselective angiographic embolization was done. Clinically, his symptoms has been ameliorated. We report a rare case of thoracic myelopathy due to spinal dural arteriovenous fistulas exclusively supplied by the branches of internal iliac artery.

Hypereosinophilic syndrome comprises several disorders with the common features of prolonged eosinophilia of an undetectable cause and organ system dysfunction. It is likely that organ damage is due to infiltration by eosinophils or to eosinophil-derived products. We report a case of hypereosinophilic syndrome with multiple mononeuropathy verified by EMG, nerve conduction study, and biosy..

Clinically, the infarction of posterior spinal arteries is rarely recognized due to rich anastomosis. As a result, there have been few clinical reports of posterior spinal artery infarction. A 38-year-old man experienced severe transitory neck and occipital pain after his friend had struck him on the cervical area. A few days later, he developed dysmetria, dysdiadochokinesia, and decreased vibration and position senses on the right side of his body. Routine laboratory find-ings, an echocardiogram, a work-up for connective tissue diseases, and CSF studies were all found to be normal. A MRI showed increased signals in the right posterior and posterolateral part of the lower medulla and some portion of the first cervical cord on T2- and proton-weighted images without significant enhancements. A cerebral angiogram showed a long narrow thread-like segment in the distal portion of the right vertebral artery, which was indicative of a dissection. The right posterior inferior cerebellar artery was not visualized.
