BACKGROUND: The analgesic properties of the nonsteroidal antiinflammatory drugs (NSAIDs) have been attributed to their effects on the peripheral synthesis of prostaglandins. Although the preoperative use of NSAIDs has been increasing because of concerns regarding the side effects of opioid analgesics but results of clinical preemptive analgesia studies remain inconclusive. So, we studied the efficacy of preemptive analgesic effects of tenoxicam, new NSAID, on postoperative continuous intravenous analgesia with morphine. METHODS: We studied 40 parturients, undergoing cesarean section, ASA class I or II, randomly divided into two groups. Tenoxicam group were injected tenoxicam 0.3 mg/kg and control group were injected normal saline 3 ml at ten min. before induction. For both groups morphine 0.1 mg/kg was administered as loading dose and 0.015 mg/kg/hr as maintenance dose. We examined verbal quantitative score (VQS) at postoperative 30 min, 1, 6, 12, 24 and 48 hr. Maternal satisfaction, side effects, hepatic and renal function also evaluated after pain control. RESULTS: The values of VQS showed no significant differences between two groups 30 min, 1 and 6hr after start of morphine infusion, but there was significant decrease in tenoxicam group compared to control group 12, 24 and 48 hr after start of morphine infusion (p<0.05). There was no significant difference in maternal satisfaction between two groups and also there were no significant differences in the overall incidences of side effects between two groups. CONCLUSIONS: Preoperative single injection of tenoxicam showed incomplete preemptive analgesic effects on postoperative pain control after cesarean section.

Hepatitis B virus (HBV) and human immunodeficiency virus (HIV) have a common route like sexually transmitted infections (STIs), vertical transmission and blood transfusion, etc. Therefore, it was necessary to be an attempt to confirm the relationship of HBV and HIV in Korea. We investigated the prevalence of Hepatitis B surface antigen (HBsAg) and Hepatitis B core antibody (anti-HBc) in HIV positive groups (n=430) and HIV negative groups (n=434) from January 2014 to October 2015. When comparing the prevalence of anti-HBc between the two groups, HIV positive group (36.0%) showed a higher prevalence than HIV negative group (24.7%), the result was statistically significant (p < 0.05). However, there was a little difference on HBsAg and not significant. Therefore, by showing a clear difference in anti-HBc between the two groups of HIV in Korea, it was confirmed to be associated with co-infections between Hepatitis B and HIV.

PURPOSE: Thanks to hepatitis B immune globulin (HBIG) and antiviral agents such as Lamivudine , HBV cirrhosis is no longer a contraindication of liver transplantation. Actually it is frequent indication for liver transplantation in Korea. However, to date, the most effective HBV prophylaxis regimen has not been determined. The purpose of this study was to evaluate whether the regimen consisting of lamivudine and one-week HBIG for the hepatitis B virus (HBV) prophylaxis following liver transplantation is as effective as a long-term therapy of high dose HBIG. METHODS: From May 1996 to December 1999, 58 patients among a total of 80 cases of liver transplantation were hepatitis B surface antigen positive preoperatively. They were grouped into two protocol regimens, the HBIG group and the Lamivudine combination group, at random. 43 patients (19 patients in the HBIG group, twenty four patients in the Lamivudine combination group) who survived more than 90 days were included in this study. The recurrence was defined as the conversion of HBs-Ag from negative to positive. RESULTS: There was no statistical significance between the two groups in regards to age, sex or the preoperative positive rate of HBeAg. The mean follow-up duration was 27 months (range from 6-55). Of the 43 patients, 5 patients were converted to HBs-Ag positive in serum; two were in theHBIG group and three in the Lamivudine combination group. There was no statistical significance in HBV recurrence rate between the two groups (p=0.97). CONCLUSION: The combined therapy of lamivudine and one week HBIG has an effect equivalent to a long term therapy of high dose HBIG in HBV prophylaxis following liver transplantation.

BACKGROUND/AIMS: As the incidence rate of and mortality from pseudomembranous colitis (PMC) are increasing worldwide, it is important to study the simple predictive risk factors for PMC among patients with hospital-acquired diarrhea (HAD). This study focused on identifying the clinical risk factors that can easily predict PMC. METHODS: The presumed HAD patients were prospectively recruited at the Hallym University Kangdong Sacred Heart Hospital. RESULTS: Age of 70 and older (adjusted odds ratio [OR], 1.76; 95% confidence interval [CI], 1.12 to 0.75), use of proton pump inhibitors (adjusted OR, 4.07; 95% CI, 2.512 to 6.57), use of cephalosporins (adjusted OR, 2.99; 95% CI, 1.82 to 4.94), and underlying cancer (adjusted OR, 1.72; 95% CI, 1.04 to 2.82) were independent risk factors for PMC in the multivariate logistic regression analysis. The prevalence of PMC was very low in the patients with HAD who exhibited no risk factors. CONCLUSIONS: The risk factors for PMC in patients with HAD included cephalosporin use, proton pump inhibitor use, old age, and cancer. Considering the strongly negative predictive values of these risk factors, endoscopic evaluation can be delayed in patients with HAD without risk of developing PMC.

PURPOSE: Sentinel lymph node biopsy became the standard procedure in early breast cancer surgery. Faculty members might be exposed to a trace amount of radiation. The aim of this study is to quantify the radiation exposure and verify the safety of the procedure and the facilities, especially during pathologic process. MATERIALS AND METHODS: Sentinel lymph node biopsies with Tc-99m human serum albumin were performed as routine clinical work. Exposed radiation doses were measured in pathologic technologist, nuclear medicine technologist, and nuclear medicine physician using a thermoluminescence dosimeter (TLD) during one month. We also measured the residual radioactivities or absorbed dose rates, the exposure distance and time during procedure, the radiation dose of the waste and the ambient equivalent dose of the pathology laboratory. RESULTS: Actual exposed doses were 0.21 and 0.85 (uSv/study) for the whole body and hand of pathology technologist after 47 sentinel node pathologic preparations were performed. Whole body exposed doses of nuclear medicine physician and technologist were 0.2 and 2.3 (uSv/study). According to this data and the exposure threshold of the general population (1 mSv), at least 1100 studies were allowed in pathology technologist. The calculated exposed dose rates (micro Sv/study) from residual radioactivities data were 2.47/ 22.4 micro Sv (whole body/ hand) for the surgeon; 0.22/ 0 micro Sv for operation nurse. The ambient equivalent dose of the pathology laboratory was 0.02-0.03 mR/hr. The radiation dose of the waste was less than 100 Bq/g and nearly was not detected. CONCLUSION: Pathologic procedure relating sentinel lymph node biopsy using radioactive colloid is safe in terms of the radiation safety.

PURPOSE: Thyroglobulin (Tg) may be released from damaged residual thyroid tissues after radioactive iodine (RAI) therapy in patients with differentiated thyroid carcinoma (DTC). We investigated whether altered levels of serum Tg after recombinant human thyrotropin (rhTSH)-aided RAI therapy could be a prognostic marker in patients with DTC.METHODS: We evaluated 68 patients who underwent RAI therapy after total thyroidectomy. Serum Tg levels were measured just before RAI administration (D0Tg) and 7 days after RAI therapy (D7Tg). Patients with a D0Tg level greater than 2.0 ng/mL were excluded to more precisely evaluate the injury effect of RAI in small remnant tissues. The ratioTg was defined as the D7Tg level divided by that on D0Tg. The therapeutic responses were classified as acceptable or non-acceptable. Finally, we investigated which clinicopathologic parameters were associated with therapeutic response.RESULTS: At the follow-up examination, an acceptable response was observed in 50 patients (73.5%). Univariate analysis revealed significant differences in N stage (P = 0.003) and ratioTg (acceptable vs. non-acceptable responses, 21.9 ± 33.6 vs. 3.8 ± 6.5; P = 0.006). In multivariate analysis, only ratioTg significantly predicted an acceptable response (odds ratio 1.104; 95% confidence interval 1.005–1.213; P = 0.040). A ratioTg above 3.5 predicted an acceptable response with a sensitivity of 66.0%, specificity of 83.3%, and accuracy of 70.6% (area under the curve = 0.718; P = 0.006).CONCLUSIONS: Altered levels of serum Tg after RAI therapy, calculated as the ratioTg (D7Tg/D0Tg), significantly predicted an acceptable response in patients with DTC.
