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.

BACKGROUND: Pregabalin is an anticonvulsant and analgesic agent that interacts selectively with the voltage-sensitive-Ca(2+)-channel alpha-2-delta subunit. The aim of this study was to evaluate whether the analgesic action of intrathecal (IT) pregabalin is associated with KATP channels in the rat formalin test. METHODS: IT PE-10 catheters were implanted in male Sprague-Dawley rats (250-300 g) under inhalation anesthesia using enflurane. Nociceptive behavior was defined as the number of hind paw flinches during 60 min after formalin injection. Ten min before formalin injection, IT drug treatments were divided into 3 groups: normal saline (NS) 20 microl (CON group); pregabalin 0.3, 1, 3 and 10 microg in NS 10 microl (PGB group); glibenclamide 100 microg in DMSO 5 microl with pregabalin 0.3, 1, 3 and 10 microg in NS 5 microl (GBC group). All the drugs were flushed with NS 10 microl. Immunohistochemistry for the KATP channel was done with a different set of rats divided into naive, NS and PGB groups. RESULTS: IT pregabalin dose-dependently decreased the flinching number only in phase 2 of formalin test. The log dose response curve of the GBC group shifted to the right with respect to that of the PGB group. Immunohistochemistry for the KATP channel expression on the spinal cord dorsal horn showed no difference among the groups 1 hr after the formalin test. CONCLUSIONS: The antinociceptive effect of pregabalin in the rat formalin test was associated with the activation of the KATP channel. However, pregabalin did not induce KATP channel expression in the spinal cord dorsal horn.

A case of Wegener's granulomatosis is described, with special attention focused on the typical histologic findings and involvement of both middle ear and lung. The patient is a 37-year-old man presented with four-month history of cough and sputum. He had a past history of surgery of both ears because of otitis media followed by left facial palsy. Chest radiographs showed variable sized ill defined nodules in both lower lobes with internal airspace consolidation. Histologic preparations of the open lung biopsy specimens demonstrated a diffusely scattered palisading micro and macrogranulomas with central focus of neutrophils and necrotic collagen surrounded by histiocytes, histiocytic giant cells. Fibrinoid necrosis involved blood vessels and lung parenchyma. Chronic inflammation, diffuse granulation tissue formation and irregular fibrosis are also found in the lung parenchyma. The histologic findings of middle ear which was previously biopsied showed scattered palisading ill defined microgranulomas mixed with fibrotic tissue.

7.Ewing's Sarcoma Mimicking a Meningioma in Radiological Findings: A Case Report.
Journal of the Korean Radiological Society 2007;57(4):327-330
Ewing's sarcoma is an uncommon primary bone tumor. Primary Ewing's sarcoma of the cranium is extremely rare and constitutes only 1% of all Ewing's sarcoma cases. Usually, primary Ewing's sarcoma of the carnium manifests as an expansile osteolytic malignant bone tumor with or without intracranial extension. We report here the radiological findings of a case of Ewing's sarcoma mimicking a meningioma in an 18-year-old man.

To our knowledge, MR findings of neuroshistosomiasis has not been reported in Korea. A case of neuroshistosomiasis involving cerebellum and presumably spinal cord is reported. A 40 year old man who had lived in Middle East complained of low back pain and progressive paraparesis for 6 months, and subsequently developed headache, dizziness and diplopia. On cervical spine MRI, there was diffuse enlargement of cervical cord with increased signal intensity on T2 weighted image and nodular heterogenous enhancement after Gd-DTP^ administration. Brain MR imaging obtained 4 months later showed ill-defined, irregularly enhancing heterogenous mass in cerebellar vermis which was proved to be a granulomatous lesion containing shistosomiasis mansoni ova.

In the past 13 years period, authors experienced 14 cases of giant cell tumor, 3 of which were treated by bone cementing after curettage. The results of various methods of treatment applied were compared and literatures surveyed. The followings were noted: 1. The most efficient method of treatment for giant cell tumor is en bloc resection. 2. The method of bone graft after curettage has such disadvantages as high recurrence rate and sequelae due to long periods of immoblization, especially for the large lesion with severe bone destruction. 3. Bone cementing after curettage seemed to be a choice in the methods of primary treatment of long bone giant cell tumor, especially useful for the tumors near the knee joint; the main advantages over other methods of treatment were considered to be technical simplicity and lack of complications.

The Kuntscher nail has been used widely for the treatment of femoral shaft fracture with the advantage of early weight bearing and early joint movement. But it has some disadvantages that are harmful in bone-union by the wide intramedullary reaming, and rotation and bending of the device. Schneider devised four flanged nail to be able to eliminate the disadvantage of the Kiintscher nail. The author have experienced the 16 cases of Schneider nailing in the fractures of femoral shaft at the Department of Orthopaedic Surgery, Ewha Womans University Hospital from Feb., 1982 to Apr., 1984. The following results were obtained. 1. There were common in male (14 cases) and active ages (13 cases). 2. The most common cause was trauma with 14 cases and the other was pathological fracture. 3. Indications of Schneider nailing were wide than those of Kiintscher nailing. 4. Usual intervals between the injury and operation was one week. 5. Mean operating time was one hour and 25 minutes, and blood loss during the operation was 410cc. 6. After treatment, we usually permitted the exercises of quadriceps setting and non-weight bering walking within 1 week, partial-weight bearing walking within 4 weeks and full weight bearing walking within 4 months. 7. The results of 13 cases among 15 cases were better than good. 8. There were no complications such deformities as rotation, shortening and angulation because of specialized structure of Schneider nail. Also, Schneider nailing could prevent the nonunion and infection because there was need of reaming the medullary canal.
