Fourty three patients known to hnve cervical intraepithelial neoplasia were assigned to Papanicolaou smear in five different ways, i, e, A) cotion tipped wood applieator at the pasterior vaginal fronix and the ectocervix, B) cotton tipped wood applicator at the ectocervix and the endocervical canal, C) Cytohrush at the endocervical canal, D) Cervexbrusk and E) Cyto-spatula. At the completion of cytologic study, all the subjects were done colposcopically directed biopsy and/or ECC. To evaluate the false negative rates of the cytologic test, cervical cone biopsy or hysteectorny was performed on all the patient. The false negat,ive rates were 53.5% in A) 39.5% in B), 14,0% in C), l8.6% in D), 25.6% in E) and statistical differences occurect between each group, It was also found that bleedings were most frequently endountered in E) and the encocervical cells were most frequently appeared in C). With these results, it can he stated that the rate of negative encocervical cells in the srnear were correlated with the false negative rates of cervical cytology.

BACKGROUND: In recent years, the incidence of extended-spectrum beta-lactamase (ESBL) producing Klebsiella has been steadily increased, and the newer species K. planticola and K terrigena, formerly regarded as nonpathogen, have been reported with astonishing frequency from human infectious processes by some investigators. The aim of this study is to elucidate the isolation rate and antimicrobial susceptibility of recent clinical Klebsiella isolates. METHOD: For the clinical Klebsiella isolates during the period of June 1999 to May 2000, isolation frequency of Klebsiella species by specimen, departments, age, and sex were analyzed. And antimicrobial susceptibilities were also analyzed. RESULT: Isolation rate of Klebsiella in order of decreasing frequency were K. pneumoniae (74:7%), K. oxytoca (12.1%), K. ozaenae(1.7%), K. planticola(1.0%), K. terngena(0.9%), and K, ornithinolytica (0.7%), respectively. K. rhinoscleromatis was not isolated. Compared with outpatients, increase of resistance rates of inpatients's Klebsiella isolates were 10% in ciprofloxacin, 15% in cefoperazone/sulbactam, and the others were ranged from 24% to 31%. Isolation rate of ESBL producing K. pneumoniae by double disk (DD) synergy test was 41%, and detection rates by antimicrobial agents were as follows: cefotaxime (95%), aztreonam (58%), and ceftriaxone (37%). Antimicrobial susceptibility rate with the exception of ampicillin and imipenem decreased from the range of 81%-96% on admission day to 29-62% after one week on admission. CONCLUSION: The isolation rates of K. planticola and K. terrigena were less than 1%. The proportion of ESBL producing K. pneumoniae was 41 %. And the vast majority of multidrug resistant Klebsiella including ESBL producing strains are acquired by hospitalization.

The addition of a monthly course of progesterone decrease the incidence of endometrialhyperplasia and endometrial carcinoma. The progesterones used in hormonal replacementtherapy(HRT) differ markedly in their progesteronic, androgenic and even estrogenicactivities. These characteristics may influence both symptomatic and metabolic side effects.The purpose of this study was to examine effect of bone and lipid metabolism inpostmenopausal women treated with conjugated equine estrogens plus dydrogesterone.A total 131 postmenopausal women(surgical menopause=95, natural menopause=36)and not-treated postmenopausal women(control=22) were invited to participate in thisstudy. Patients were divided into groups which had received conjugated equine estrogen(CEE)0.625 mg/day 21-day-cycle each month(n=20), CEE 0.625 mg/day plus Dydrogesterone 10mg/day 10-day-cycle each month(n=111), and no treatment control group(n=20).Serum lipid and lipoprotein(Triglyceride, Total cholesterol, High density lipoprotein, Lowdensity lipoprotein) and serum osteocalcin, urinary Deoxypyridinoline were examined in allpatients.There were no significant differences in bone and lipid metabolism between CEE andCEE plus Dydrogesterone groups.In conclusion, Dydrogesterone may be used safely in postmenopausal women withoutMetabolic side effect.

The cesarean section has been considered as one of the most prime and most commonly performed operations in the obstetrics and gynecology field. In fact, all cesarean sections have depended upon the operator`s experience. However, there have been several cases reported on new technique of cesarean section in many developed countries, but not in Korea until we started the recent research. We have developed a new type of cesarean section named FAST(Finger Assisted Stretching Technique) through study on strength/weakness of other operation techniques as well as many other researches we conducted in the past plus our own experiences. To find the differences on the following subjects; operating time, postoperative complication, and recovery period. We compared and analyzed data from using new and traditional techniques. We selected 120 patients(group A using FAST: 45 patients, group B using traditional technique: 75 patients) as samples for this study. Together, they were all conducted cesarean section at Korea University, Guro Hospital between May 1993 and December 1995. Student-t-test and chi-square test were used for statistical analysis. We consider that below 0.05 for P value is statistically significant. The results of comparative study between two groups are; 1. There was no comparative difference on average age: group A: 29.6(range 23~39, S/D 7.1) group B: 31.1(range 24~38, S/D 5.4) 2. There was a significant difference on average operation times: group A: 15.4 min.(range 11~19, S/D 3.6) group B: 41.3 min.(range 23~50, S/D 19) 3. There was a significant difference on average amount of bleeding: group A: 580 ml(range 450~750, S/D 101) group B: 916 ml(range 800~1000, S/D 99) 4. There was a significant difference on the value of hemoglobin before and after operation group A: 0.8 g/dl(range 0.4~1.6, S/D 0.25) group B: 1.9 g/dl(range 0.9~2.6, S/D 0.21) 5. There was a significant difference on average period of hospitalization: group A: 3.7 days(range 3~4, S/D 0.7) group B: 6.4 days(range 5~8, S/D 0.6) 6. No one from group A experienced any infection, but 3 cases of wound infection and 2 cases of voiding difficulty were reported from group B. 7. 11 cases from group A and 16 cases from group B had laparotomy for some other reasons, later. There was no adhesion found in group A, but adhesions found in 2 cases from group B.

BACKGROUND: The identification of in vitro hemolysis (IVH) using a hematology analyzer is challenging because centrifugation of the specimens cannot be performed for cell counts. In the present study, we aimed to develop a scoring system to help identify the presence of hemolysis in anticoagulated blood specimens. METHODS: Thirty-seven potassium EDTA anticoagulated blood specimens were obtained, and each specimen was divided into 3 aliquots (A, B, and C). Aliquots B and C were mechanically hemolyzed by aspirating 2 and 5 times, respectively, using a 27-gauge needle and then tested; aliquot A was analyzed immediately without any hemolysis. After the cells were counted, aliquots B and C were centrifuged and the supernatants were tested for the hemolytic index and lactate dehydrogenase levels. RESULTS: The 4 hematologic parameters were selected and scored from 0 to 3 as follows:< 34.0, 34.0-36.2, 36.3-38.4, and > or =38.5 for mean cell hemoglobin concentration (MCHC, g/dL); <0.02, 0.02, 0.03, and > or =0.04 for red blood cell ghosts (10(12)/L); <0.13, 0.13-0.38, 0.39-1.30, and > or =1.31 for difference value (g/dL) of measured hemoglobin and calculated hemoglobin; and <0.26, 0.26-0.95, 0.96-3.34, and > or =3.35 for difference value (g/dL) of MCHC and cell hemoglobin concentration mean. The hemolysis score was calculated by adding all the scores from the 4 parameters. At the cutoff hemolysis score of 3, the IVH of aliquots B and C were detected as 64.9% and 91.9%, respectively. CONCLUSIONS: The scoring system might provide effective screening for detecting spurious IVH.

Aerococcus viridans, a catalase-negative gram-positive coccus rarely causing bacteremia, was isolated from blood cultures of a 52-yr-old man under the gran-ulocytopenic condition. The isolate showed the typical characteristics of A. viridans, i.e., tetrad arrangements in gram stain, positive pyrrolidonyl aminopeptidase (PYR) and negative leucine aminopeptidase (LAP) reactions, and no growth at 45 degrees C.The isolate was revealed to be highly resistant to penicillin, erythromycin, clindamycin, and ceftriaxone, although most strains of A. viridans isolated from the previously reported patients were susceptible to penicillin and other commonly used antibiotics. Even though A. viridans is rarely associated with human infections, it could be a potential causative agent of bacteremia, especially in immunocompromised patients.

BACKGROUND: The VITEK-2 yeast susceptibility test (AST-YS01; bioMerieux, Hazelwood, MO, USA) has recently been introduced as a fully automated, commercial antifungal susceptibility test system that determines MIC endpoints spectrophotometrically, thereby eliminating subjective errors. We compared the ATB FUNGUS 2 (bioMerieux) and VITEK-2 (AST-YS01) systems to the CLSI M27 method for susceptibility testing of Candida isolates. METHODS: We tested 59 Candida species that were isolated from blood cultures at Wonju Christian Hospital between September 2008 and August 2009. We compared MIC results for amphotericin B, flucytosine, fluconazole and voriconazole using the ATB FUNGUS 2 and VITEK-2 (AST-YS01) tests to those obtained by the CLSI M27 broth microdilution method. RESULTS: Within two-fold dilutions of MICs, the agreement of the ATB FUNGUS 2 and VITEK-2 (AST-YS01) tests with the CLSI method according to antifungal agents were: amphotericin B, 100% vs. 100% flucytosine, 100% vs. 100% fluconazole, 83.6% vs. 98.3% and voriconazole, 83.6% vs. 96.7%, respectively. The categorical discrepancies for fluconazole and voriconazole were 20.4% and 18.6% for ATB FUNGUS 2, and 6.8% and 0% for VITEK-2 (ASTYS01). There were no major errors for fluconazole and voriconazole in either ATB FUNGUS 2 or VITEK-2 (AST-YS01) tests. CONCLUSION: The VITEK-2 system (AST-YS01) appears to be rapid and highly correlative with the CLSI method, suggesting that it is effective for antifungal susceptibility testing for Candida species in clinical settings.
