PURPOSE: The objective of this study was to evaluate an immunoassay for urinary nuclear matrix protein (NMP22) as an indicator for transitional cell carcinoma of the bladder. MATERIALS AND METHODS: Three groups of subjects attended the trial of NMP22. First group was 27 patients with transitional cell carcinoma of the bladder, second group was 24 patients with other urinary cancer consisted of prostate cancer and renal cell carcinoma, and third group was 24 healthy volunteers. NMP22 was determined using a commercial test kit, which is based on an enzyme-linked immunosorbent assay. RESULTS: In normal healthy volunteers and other urinary cancer group median NMP22 levels were 2.24 and 3.27 U/ml, respectively. Median urinary NMP22 levels in patients with transitional cell carcinoma of the bladder were 54.30 U/ml. It was significantly greater than other two groups. Median NMP22 levels according to the tumor stage and the tumor grade did not show the significant difference statistically. CONCLUSIONS: Urinary NMP22 is a useful marker that is more specific for bladder cancer thsn for other urinary cancer. Further tests are required to clarify the influence of other spe- cific conditions, such as urinary tract infection, and intravesical drug instillation or procedure.

We tried to find out any differences between initial characteristics of androgen receptors and of relapse after castration in 6 stage D2 prostatic cancer (mean age, 68.7+/-4.6) (Gleason score 5, 8, 9 ; 1,3, 2 patients respectively), with immunohistochemical expression using the mouse monoclonal antibody against human androgen receptor. The prostate specimens were obtained by either transrectal needle biopsy or transurethral resection at the time of initial diagnosis and of relapse following castration. The age matched 6 benign prostatic hyperplasia (BPH) specimens were used as control. 200 cancer cells were chosen and staining intensity of each nuclei was graded (O-absent, +1-weak, +2-moderate, +3-strong) from randomly selected and photographed from 10 different fields of each specimen. The means of staining intensity of nuclei from BPH and prostatic cancer before treatment were 1.93+/-0.03 and 1.59+/-0.03 respectively (p<0.05). At the time of relapse after bilateral orchiectomy (mean, 24.5+/-5.0 months), the mean staining intensity of nuclei of all cancer patients (1.38+/-0.03) was significantly different from that of before treatment (p<0.05). But in individual comparison, we could find the decrement in only 2 patients. The intervals of relapse from castration of these two patients (29 and 32 months) were longer than the mean of 6 patients. In conclusion, androgen receptors are still expressed significantly after castration in prostatic cancer. In some patients (2/6), castration down regulates the expression of androgen receptors and the down regulation closely correlated with the relapse time."

The diagnosis of acute undifferentiated leukemia is made when the leukemic cells cannot be classified using morphologic and cytochemical analyses, and do not express myeloid or lymphoid antigens. Trisomy 13 is a rare primary chromosomal abnormality in acute leukemia and associated with lineage inconsistency and poor prognosis. We report a rare case of acute undifferentiated leukemia showing negativity in periodic acid-Schiff (PAS) and myeloperoxidase (MPO) without any lineage-specific cell surface marker expression and having trisomy 13. The patient was a 72- year-old male who visited our hospital because of anemia and general weakness. On examination, leukocytosis with proliferated blasts (76%) in peripheral blood was noted. Bone marrow aspirate showed blast proliferation (74%) with morphologically hand-mirror type. The blast expressed CD34 (96%) and HLA-DR (76%) in immunophenotyping. Cytogenetic study of bone marrow cells showed 46,XY,+13,-21[15]/46,XY[5]. Induction chemotherapy was failed and differentiation to monocytic series was noted.

Duodenal diverticulum is commonly found at 2nd portion of duodenum undergoing duodenal procedure. It is generally asymptomatic and not harmful. But occasionally it causes massive upper gastrointestinal bleeding. Bleeding from duodenal diverticulum is very difficult to diagnose and manage since vision of the lesion by conventional direct endoscope is limited. Recently, emphasis has been placed on aggressive and careful endos- copic diagnosis and hemostasis with hemoclip or local injection. We report a case of massive duodenal diverti- cular bleeding on a senile patient which was treated successfully by endoscopic hemoclip therapy.

Recently the use of I-PSS (International prostate symptom score) is highly recommended for the evaluation of symptomatic benign prostatic hyperplasia (BPH) and many linguistic translations have been made. Regardless the validity and reliability of linguistic translation, there might be several social and cultural factors which affect to the symptom severity in BPH. We tried to show the prevalence of prostatism and the effect of social and cultural background which could affect to the results I-PSS questionnaire in Korea. A total of 841 men (40~79 years) who visited 4 health care center were included. Because of 107 men had medico-surgical history relating to voiding, final eligible subjects were 734. Total symptom scores increased by age decades (40~49, 50~59, 60~ 69, 70~79; median 7, 8, 11, 12 respectively). The rate of mild (0~7); moderate (8~19); and severe (20~35) symptom in 40th, 50th, 60th and 70th were 55.5%; 39.3%; 1.2%, 45.4%; 46.5%; 8.1%, 30.4%; 53.9%; 15.7% and 28.1%; 43.8%; 28.1% respectively. One cause of these high prevalence of prostatism in Korea is relatively very small proportion of readily treated BPH patients in general population (0.5%). Another factor of the high prevalence of prostatism is thought to be the different social and cultural concept to voiding status. These factors limit comparability of I-PSS questionnaire between different countries.

Recently developed International Prostate Symptom Score(I-PSS) is highly recommended for the evaluation of urinary symptoms in benign prostatic hyperplasia(BPH) and many linguistic translations have been made. English version of I-PSS was translated into Korean. Three groups of urologists and ordinary people participated for the translation and back-translation of I-PSS. A Korean version was finalized and translation validity was assessed by a survey with 48 English speaking Korean aged men. Test-retest reliability was confirmed by an another questionnaire survey with 76 aged men. Translation of I-PSS into Korean was valid. The I-PSS Korean version was internally consistent and sensitive as well as specific for the discrimination of symptomatic groups. Also test-retest reliability was acceptable.

We experienced a case in which yeasts in blood sample from a patient with cervical cancer with hepatic metastasis and multiple intraperitoneal cysts interfered with platelet morphology flag in automated blood analyzer. The peripheral blood smear was performed to confirm the flag and revealed intracellular and extracellular yeasts, which were subsequently identified as Candida parapsilosis by blood culture.

Prostate-specific antigen(PSA) in serum exists in several molecular forms that can be measured by immunodetectable assays; free PSA, PSA complexed to alpha1-antichymotripsin and total PSA, which represents the sum of the free and complexed forms. We have determined the amount and ratio of these forms may be seful for increasing the ability of PSA to be used in distinguishing prostate cancer(PCa) from benign prostatic hyperplasia(BPH). We evaluated 117 asymptomatic healthy male controls(mean age 55.8, range 50-71) with no clinical evidence of PCa, 125 men with symptomatic BPH(mean age 67.6, range 52-89) who underwent prostatic surgery(open prostatectomy or TLRP) and 14 men with biopsy-proven, untreated PCa(mean age 71.3 range 54-86). Using ACS-PSA2 assay(Ciba-Corning). we measured the free PSA(F), total PSA(T) and free/total(F/T) ratio. The method utilized was monoclonal-polyclonal immunometric, chemiluminescent assay, using a standardized calibrator 90:10. We also performed total PSA measurement with Tandem-R PSA assay(Hybritech). Correlation between ACS-PSA2 assay and Tandem-RPSA assay was excellent (r2=0.93). Receivr operating characteristics(ROC) analyses between them showed very similar performances. ROC analysis of free to total PSA ratio was more superior than that of free form PSA only. When all subjects were included, the ratio of free to total PSA in controls, BPH and PCa were 0.27, 0.24 and 0.07, respectively. which significantly differentiated between PCa and benign conditions(p<0.01). When the cut-off value (Fr) was set into 0.12, its diagnostic sensitivity and specificity were 86% and 84%, respectively. These findings suggest that free to total PSA ratio may enhance the ability to distinguish benign histologic conditions from cancer.
