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: The combination of Philadelphia chromosome (Ph) and monosomy 7(-7) was rarely observed in acute lymphoblastic leukemia (ALL). With the results from immunophenotyplc and molecular analysis, Philadelphia chromosome positive ALL with monosomy 7[Ph(+)/-7] has been considered that it may be derived from neoplastic transformation at the pluripotent stem cell level. We compared the clini-cal, laboratory, and hematological findings between 5 cases of Ph(+)/-7 and 5 cases of Ph(+) without monosomy 7 [Ph (+) /N7]. METHODS: During the period from January, 1995 to December, 1996, total 72 cases of ALL were confirmed among 259 cases of hematologic malignancy with bone marrow cytogenetic analysis. Among 72 ALL cases, 5 cases of Ph(+)/-7(monosomy 7 or 7q abnormalities) were compared with Ph only or Ph without monosomy 7(ph(+)/N7] on the hematological, immunophenotypic, other laboratory, clinical findings and event ree survival (EFS) The karyotyping of the bone marrow specimens was analysed byshort-term unsynchronized culture methods such as overnight colcemid treatment and 24 hours incubation following ethidium bromide treatment. RESULTS: The mean age of Ph(+)/-7 was 30.6+/-12.8 years, and it was significantly different from that of Ph(+)/N7 (p=0.009), Four cases of Ph(+)/-7 were classified as ALL L2 subtype, and 2 cases revealed CNS involvements. Immunophenotyping was positive in CD10, CDl9, CD2O, CD22 and HLA-DR. But one case revealed e-B-lymphoid lineage with positivity in CD34, CDl3, and CD33. The response to chemotherapy and EFS was very poor in Ph(+)/-7 group, and the mean EFS was 3.2+/-1.9 months(p=0.014). All of cases showed induction on failure in chemotherapy, relapsed with bone marrow, CNS and extramedullary involvements, and expired due to sepsis. CONCLUSIONS: Ph(+)/-7 ALL had very Poor clinical course with being resistant to chemotherapy and unfavorable prognosis, revealed L2 subtype by FAB classification, and was slightly older in ages compared with Ph(+)/N7 ALL.

Vibrio metschnikovii is worldwidely distributed in the aquatic environment and human infections are very rarely associated, such as septicemia, urinary tract infection, wound infection, and peritonitis. V. metschnikovii is negative in nitrate reduction and oxidase reaction, and these findings are different from other vibrio species. V. metschnikovii was isolated from the ascitic fluid and blood of a patient with peritonitis, sepsis and renal insufficiency. This patient was a 41-year old man who suffered from post-necrotic liver cirrhosis, chronic hepatitis B, gastric ulcer, esophageal varix bleeding, and alcoholism. He had neither history of ingestion of seafoods nor exposure to seawater before onset of illness. He was successfully treated with antimicrobial agents. This is the first case report of septicemia and peritonitis by V. metschnikovii in Korea.

Hematuria is a important clinical sign that is a consequence of significant fenal. urologic or sytemic disease. Recently the morphology of the red cell in hematuria has been used to indicate a renal or non-renal source and also the measurement of red cell volume by red cell analyzer has been used to distinguish glomerular from non-glomerular hematuria. In this study. the MCV(mean corpsular red cell voume). RDW(red cell distribution width) and HDW (hemoglobin distribution width) were measured using H-1 system in57 children with hematuria to assess the diagnostic usefulness of the urinary red cell analyzer in the differentation of glomerular and non-glomerular hematuria. The patients were divided into two groups as glomerular diseases(40cases)and non-glomerular diseases(17 cases)and the location of the bleeding was confirmed by renal biopsy, radiology and the clinical findings. The results were as follows. 1) The urinary red cell MCV waslower in patients with glomerular diseases than that in patients with non-glomerular diseases (79.89 +/- 12.0fl vs. 90.93 +/- 9.71fl vs. 90.93+/-9.71 fL; p<0.01) 2) The urinary RDW and HDW were significantly higher in glomerular diseases than those in non-glomerular diseases (RDW; 19.86 +/- 11.28% vs 11.34+/-5.88%, HDW; 3.37+/-2.07 gm vs. 1.86+/-1.43gm). 3) The urinary red cell MCV was correlated well with the RDW and HDW while there was no correlation between the urinary red cell MCV and the urinary SG or pH. 4) The sensitivity, specificity and positive predictability of the urinsary MCV were 37.8%, 94.1% and 93.7% and those of RDW were 62.5%, 82.3% and 89.2% 5) The sensitivity, specificity and positive predictability of the urinary HDW were 42.5%, 88.2% and 89.4% We concluded from above date that the measurment of the urinary MCV, RDW and HDW would be useful as a primary non-invasive screening test in differentation of glomerular and non-glomerular hematuria in children.

BACKGROUND: In spite of appropriate therapy and control for tuberculosis, the prevalence of tuberculosis is still frequent in Korea. Emerging infection and rapid detection of multidrug-resistant Mycobacterium tuberculosis (MDR-TB) are major interests in microbiologic laboratories. In this study, we evaluated the usefulness of random amplified polymorphic DNA (RAPD) genotyping for molecular epidemiological characteristics of MDR-TB. METHODS: We analyzed 64 clinical strains of M. tuberculosis including 35 strains which showed resistance to one or more antimycobacterial drugs and M. tuberculosis H37Rv (ATCC 27294), as a drug-sensitive control strain. RAPD genotyping analysis was carried out under eight reaction conditions and using ten random primers (A-1245, AP-50, B-1245, DKU-44, DKU-49, Leg-1, INS-2, IS-986-FP, PF-15 and MBR). RESULTS: RAPD patterns using six primers (IS-986-FP, DKU-44, DKU-49, INS-2, B-1245, and AP-50) showed marked polymorphisms that were easier to discriminate than those with other primers. RAPD patterns represented various polymorphisms among 64 strains. However, RAPD could not discriminate MDR-TB strains from drug-sensitive ones. CONCLUSIONS: RAPD genotyping is assumed a preferable technique for discrimination among clinical strains of M. tuberculosis but not for specifying MDR-TB strains.

We have experienced a case of pericardial tuberculoma, a very rare disease, with massive pericardial effusion in a 63-year-old veteran. He wdimensional echocardiography. Computed tomographic scans confirmed the presence of a pericardial mass and clinically unsuspected "lung mass". The presence of the lung mass led us a diagnostic and therapeutic dilemma. Surgery confirmed the pericardial mass which revealed tuberculosis by patholohy and loculated pleural effusion at the major fissure, so-called "phantom tumor", not a lung mass.
