PURPOSE: The results of ceramic-on-ceramic (CoC) bearing surfaces in primary total hip arthroplasty (THA) were well known. However, it was not known in revision THA. The purpose of this study is to report the results of revision THA with ceramic articulation. MATERIALS AND METHODS: A total of 112 revision THAs were evaluated. The mean age at the time of surgery was 51.6 years (27.7 to 84.2 years). The mean duration of the follow-up periods was 6.3 years (2.3 to 11.4 years). RESULTS: The Harris hip scores improved from an average of 56.2 at the index surgery to an average of 93.3 at the last follow-up (P<0.001). None of hips showed osteolysis or ceramic head fracture. One hip showed aseptic loosening in the acetabular component with squeaking that caused a re-revision. There were nine cases of dislocation. The survivorship at 5 years was 94.5% (95% confidence interval, 87.9% to 97.6%) with revision for any reason as the endpoint and 100% with femoral revision. CONCLUSION: The ceramic articulation is one of good bearing options for revision THA in patients with a long life expectancy.

Cervical cancer and its precursors are caused principally, if not exclusively, by HPV infection and HPV DNA is found in more than 90% of cervical cancers. Cervical cytology is limited by its false negativity and this may be supplimented by other adjunctive test such as HPV test. It is therefore important to explore the use of HPV DNA detection as a primary or supplementary screening method and to determine whether HPV typing can be used as a predictor of a lesion's clinical behavior. Cervical cytology and Hybrid Capture test for HPV detection were performed in 450 asymtomatic wornen visited Health Care Center in Kangnam St. Mary's Hospital,and none of whom was believed to have current cervical disease. The Papanicolaou cytology results were classified by The Bethesda System : 333(74.%) women were classified to within normal limit, 19(4.2%) benign reactive change, 38(8.4%) ASCUS, 59(13%) low grade SIL, and only one woman high grade SIL. Twenty five of 450(5.6%) women showed HPV infection by Hybid Capture test. Among 98 wornen with abnormal Papanicolaou cytology, 16(16.3%) women showed HPV DNA positivity. (continue)

BACKGROUNDS/AIMS: Growth of tumors and their metastases is dependent on factors that stimulate vessel formation (angiogenesis). Vascular endothelial growth factor (VEGF) is closely related to angiogenesis in various human cancers. The aim of this study was to determine the value of serum VEGF levels in hepatocellular carcinomas as a tumor marker. METHODS: We measured serum VEGF levels, by enzyme immunoassay, and platelet counts in healthy controls (n=22), liver cirrhosis (LC; n=4) and hepatocellular carcinomas (HCC; n=14). RESULTS: The mean serum VEGF levels in controls and the patients with LC and HCC were 251.8+/-121.5 (mean+/-SD), 163.4+/-82.1 and 557.8+/-520.3pg/ml, respectively. The levels were significantly elevated in the HCC group, compared with the control group (p<0.05). Serum VEGF levels in the HCC group were highly correlated with platelet counts (r=0.915, p<0.05). Conclusions : We consider that serum VEGF is a possible tumor marker for HCC. Serum VEGF may be partly derived from platelets.

BACKGROUND/AIMS: Hepatocytes on the hepatic lobule mipate from portal zone to centrilobular mea as the DNA synthesis within it. And also, the xenobiotic reactions reveal characteristic differences associated with zone specific metabolism in the liver acinus. In this study, the zonal distribution of ethylnitrosourea (ENU)-induced hepatic precancerous lesion was stereologically investigated. METHODS: Nine B6C3F1 mices were given I.p. injection of ENU (60 ug/pn body weight) when the pups were 15 days old prior to sacrifices at 8 weeks of life. All the 150 consecutive sections, 3 p m in thickness, were stained with hematoxylin and eosin and identified the basophilic precancerous lesions with 80-165 p m diameter in equatorial plane by the Zeiss microprojector. And then the distances from the center of selected foci to terminal hepatic vein or portal vein branches were estimated under the microscopic fields. As a control group, the same estimations were performed from the random points by the appointments of random digit table. RESULTS: Mean distance between ENU-induced 52 hepatocellular foci and the nearest terminal hepytic vein was 181.15+112.39 p m (Mean+ SD), but that of randomly selected 104 points was 291.73+157.98pm (Mean+5D) (Students t-test, p<0.0005). Substantially, 52.7% of ENU-induced 52 hepatocellular foci were within 300 p m from the terminal hepatic vein, but randomly selected 104 points were only 50.9% (Shapiro Wilk W test, w=0.819857, p=0.048038). Mean distance from ENU-induced 52 foci to portal vein was 398.85+149.98pm (Mean+SD), but that from the randomly selected 104 points was 315.87+145.79 pm (Mean+SD)(Students t-test, p<0.0005). CONCLUSION: Stereologically, ENU-induced mice liver cell foci distribute non-randomly to Zone III, centrilobular zone of mouse hepatic acini where promote invasion toward terminal hepatic veins.

A new phenolic compound and three known flavonoids isolated from the MeOH extracts of Lespedeza tomentosa. Based on spectral data, the isolated compounds were identified as methyl 4,5-dihydroxy-3-methoxy-2-(3-methylbut-2-en-1-yl)benzoate (1), 1-methoxylespeflorin G11 (2), farrerol (3) and 1-methoxylespeflorin I2 (4). Methyl 4,5- dihydroxy-3-methoxy-2-(3-methylbut-2-en-1-yl)benzoate (1) is newly isolated from plant source.

Central nervous system cryptococcosis is common in the AIDS patients with reported incidences ranging from 1.9% to 11.0%. Cryptococcosis may be the initial manifestation of HIV infection or occur simultaneously with other opportunistic infections. HIV-infected patients with central nervous system cryptococcosis complain of fever, headache, nausea and vomiting, and cognitive dysfunction. Meningeal signs and photophobia are less common than in HIV-negative patients. Focal neurologic signs and seizures are uncommon. Disseminated cryptococcosis is often concomitantly found at the time of central nervous system cryptococcosis. We report a case of 49 year-old Korean female with HIV infection who died of disseminated cryptococcosis with autopsy findings.

Leclercia adecarboxylata is a motile, Gram-negative, facultative anaerobic bacillus of the Enterobacteriaceae family. L. adecarboxylata is an opportunistic human pathogen that phenotypically resembles Escherichia coli, although L. adecarboxylata has been rarely isolated from clinical specimens. Here we report a case of diabetic foot infection due to L. adecarboxylata, which has never been reported in Korea.

Cases of anaerobic bacteremia are rare, and the clinical impact of clostridial bacteremia remains to be clarified. Previous clinical reports have suggested that C. bifermentans is less virulent than other Clostridia species. This microorganism has occasionally been reported to cause septic arthritis, necrotizing pneumonia with empyema, brain abscesses, endocarditis, and metastatic osteomyelitis. Herein, we report on a case of C. bifermentans bacteremia in a patient with myelodysplastic syndrome in South Korea.
