According to the reports, the prevalence of anti-HCV is about 1%. In past, the results of the prevalence of HBs Ag & HBs Ab in the patients of Hansen's disease were reported. But we don't know about that of anti-HCV. So we study about the prevalence of serum anti-HCV of 60 patients & PALS of Hansen's disease. And we test about Alk. Phosp., ALT, AST, Gtlc HBs Ag & HBs Ab. 1. The prevalence of anti-HCV is 8.33%. It is higher than past reports(about 1-2%). 2. The prevalence of HBs Ag is 3.4% & that of HBs Ab is 36.3%. 3. Because of the high prevalence of anti-HCV in the patients of Hansen's disease & PALS, we think that more studies are need about it.

Malignant tumor have hypoxic cell fraction, which makes radio-resistant and hypoxia in tumor is a result from the blood flow decrease caused by increase in blood flow resistance. Blood viscosity increase is major factor of increased blood flow resistance and it could be attributed to the decrease in blood deformability index. For the evaluation of the change of blood viscosity and blood deformability in oral squamous cell carcinoma, we perform the test of the change of those factors between the normal control group and oral squamous cell carcinoma cell patient group. Relative viscosity measured against distilled water was 5.25+/-0.14 for normal control group, and 5.78+/-0.26 for the SCC patient group and there was statistical significance between the groups. However, there was no significant difference between the groups in blood viscosity between the groups by tumor size (T1+T2 vs T3+T4). Also, there was no significant difference between the normal control group and SCC patient group in blood deformability index and between the groups by tumor size (T1+T2 vs T3+T4). Increase in blood viscosity was confirmed with this study and it can be postulated that modification blood viscosity might contribute to decrease of hypoxia fraction in oral squamous cell carcinoma, thus improve the effect of radiotherapy and it can be assumed that the main factor of blood viscosity increase is not decrease of blood deformability in oral squamous cell carcinoma.

BACKGROUND: When managing patients who require repeated venous access, gaining a viable intravenous route has been problematic. To improve the situation, various studies on techniques for venous access have been conducted. The aim of this study is to evaluate the clinical results of complications following totally implanted central venous access port (TICVAP) insertion. METHODS: A retrospective analysis was conducted on 163 patients, from December 2008 to March 2013. The occurrence of complications was studied in three separate periods of catheter use: the intraoperative period, postoperative period, and period during the treatment. RESULTS: A total of 165 cases of TICVAP insertions involving 156 patients were included in the final analysis. There were 35 complications (21%) overall. Among these, 31 cases of complications (19%) occurred during the treatment period and the other 4 cases were intraoperative and postoperative complications (2%). There were no statistically significant differences in age and gender of the patients between the two groups to be risk factors (p=0.147, p=0.08). Past history of chemotherapy, initial laboratory findings, and the locations of TICVAP insertion also showed no statistical significance as risk factors (p>0.05). CONCLUSION: Because the majority of complications occurred after port placement and during treatment, meticulous care and management and appropriate education are necessary when using TICVAPs.

Purpose: The purpose of this study is to evaluate the value of proliferation factors, Ki67 and PCNA, as prognostic markers predicting the survival and neck metastasis in patients with oral cancer. Methods: 101 patients with HNSCCs, were followed retrospectively for a median period of 60 months(from 16 to 82 months). All tumors were resected surgically and examined by conventional light microscopy, immunohistochemistry. The age, sex, tumor location, clinical stage(size), metastasis, proliferative activity index(assessed by proliferating cell nuclear antigen(PCNA) and Ki67 immunoreactivity) were considered as potential prognostic factors and were correlated with patient survival. Results: Ki67 staining results ranged from 5% to 80% of tumor cell nuclei, with a median of 25%. PCNA staining results ranged from 1% to 90% with a median of 50%. With a cut-off point of 25%, patients with lower Ki67 scores showed survival advantages over those with higher Ki67 scores (p=0.0089). With cut-off point of 50%, patients with lower PCNA scores showed survival advantages over those with higher PCNA scores (p=0.0104). Pathologically neck node positive patients(n=27) showed higher PCNA expression(p=0.02) than pathologically negative neck node patients(n=39). Conclusions: The lower expressions of Ki67 and PCNA were associated with favorable prognosis such as higher survival rate and lower neck node metastasis.

Ameloblastomas are generally considered to be benign tumors of odontogenic epithelial origin with high local recurrence. Rarely ameloblastomas exhibit malignant behavior with development of metastases. In this report, we present a 19-year-old woman with ameloblastoma in the right ascending ramus and multiple recurrences. Eleven years after first therapy, ameloblastoma metastasized to ipsilateral submandibular lymph node. We also review literature about cause, treatment and work-up of malignant ameloblastoma.

BACKGROUND: The safety and clinical effectiveness data of peramivir in the real clinical field are limited. A prospective observational study was conducted based on the post-marketing surveillance data to evaluate the post-marketing safety and effectiveness of peramivir in Korean adults with seasonal influenza. METHODS: Among adults aged 20 years or older who were diagnosed with influenza A or B, patients who started peramivir within 48 hours from the initial symptoms of influenza were enrolled. All adverse events (AEs) that occurred within 7 days after administration of peramivir were checked. For the evaluation of effectiveness, changes in the severity of influenza symptoms and daily living performance were examined before and 7 days after the administration of peramivir. The date on which influenza related symptoms disappeared was checked. RESULTS: A total of 3,024 patients were enrolled for safety evaluation and 2,939 patients were for effectiveness evaluation. In the safety evaluation, 42 AEs were observed in 35 (1.16%) patients. The most common AE was fever. AEs were mostly rated as mild in severity. Serious AEs were observed in 10 patients and two of them died. However, both deaths were considered to be less relevant to peramivir. In the effectiveness evaluation, the severity of influenza symptoms decreased by 10.68 ± 4.01 points and daily living performance was improved 5.59 ± 2.16 points. Influenza related symptoms disappeared on average 3.02 ± 2.39 days after peramivir administration. CONCLUSION: Peramivir showed a tolerable safety profile and acceptable effectiveness in Korean adult patients with seasonal influenza.

PURPOSE: To evaluate the incidence and clinical features of age-related macular degeneration (AMD) in Korea. METHODS: Web-based (www.armd-nova.or.kr) registration was conducted for AMD patients aged 50 or more who were newly diagnosed by retinal specialists in Korea from August 20, 2005 to August 20, 2006. Patient data including ophthalmologic examination, fundus photography, fluorescein angiogram and/or indocyanin green angiogram (ICG), past medical history, behavioral habit, combined systemic diseases were up-loaded. RESULTS: Among finally enrolled 1,141 newly diagnosed AMD patients, 690 patients (60.5%) were male and 451 patients (39.5%) were female. The average age of AMD patients was 69.7+/-8.0. Early AMD was observed in 190 patients and 951 patients had late AMD. Classic choroidal neovascular membrane (CNVM) was observed in 18.6% of exudative AMD patients and 63.4 % had occult CNVM. Subfoveal CNVM was observed in 80.4% of the patients with CNVM. Among the 580 exudative AMD eyes that performed indocyanin green angiography (ICG), 184 eyes (31.7%) had polypoidal choroidal vasculopathy (PCV) and 36 eyes (6.2%) showed retinal angiomatous proliferation (RAP). Age, male gender, smoking, diabetes and hypertension significantly increased the risk of the AMD among Koreans. CONCLUSIONS: Because of the low rate of participation by retinal specialists, definite incidence of AMD was not obtainable. However, the estimated 1-year AMD incidence in the Pusan area of Korea is at least 0.4%. In contrast to Western people, 31.7% of exudative AMD cases were revealed to be PCV and 6.2% were revealed to be RAP. This discrepancy between ethnic groups should be considered in the diagnosis and treatment modality selection of Korean AMD patients.
