BACKGROUND: The last two decades have seen an increase in the incidence of cesarean section. Spinal anesthesia has been popular in cesarean delivery because of the ease and effectiveness, as well as the rapidity in estabilishing adequate levels of analgesia. The clinical effects of subarachnoid administeration of preservative-free fentanyl were assessed in 30 healthy women who underwent cesarean section with spinal anesthesia using 0.5% hyperbaric bupivacaine. METHODS: Sixty parturients were allocated to group I; bupivacaine (n=30) only and group II; bupivacaine/fentanyl mixture (n=30) in random order. The dose of bupivacaine varied from 9~10 mg depending on the patients height. Maximum level of sensory blockade, time to reach T4 level, incidence of hypotension, time to get complete motor recovery, perioperative analgesic effect and complications were evaluated. RESULTS: There were no differences in maximum level of analgesia, time to reach T4 level and to get complete motor recovery, and incidence of hypotension between two groups. However, duration of analgesia was longer in group II with the bupivacaine/fentanyl mixture (191.9 +/- 77.6 min) than in group I with the bupivacaine alone (74.2 +/- 30.8 min). Spinal anesthesia was excellent in 100% of the fentanyl mixture group but in 80% of the bupivacine only group. CONCLUSION: 0.5% hyperbaric bupivacaine mixed with 25 g fentanyl provided improved perioperative analgesia without affecting the onset of sensory blockade and duration of motor blockade.

Experimental measurements of dose characteristics with pentagonal applicator at nominal energy of 4, 6, 9, 12 and 15 MeV electron beam were performed for intraoperative radiotherapy (IORT) in ML-15MDX linear accelerator. This paper presents the percent depth dose, surface dose, beam flatness and output factors of using the IORT applicator in different electron beam energy. The output factor showed as a 24 percent higher in IORT applicator than that of reference 10x10 cm? applicator. The surface dose of using the IORT applicator showed 7.7 and 2.7 percent higher than that of reference field in 4 and 15 MeV electron beam, respectively. In our experiments, the variation of percent depth dose was very small but the output factor and flatness at 0.5 cm depth have showed a large value in IORT applicator.

Carcinoma of extrahepatic biliary tract is slow growing tumor but curative resection is rarely successful, Radiation therapy has been introduced for enhancing palliation and possible longterm survival. We treated a case of advanced extrahepatic biliary tract carcinoma with high dose rate remote afterloading system through T-tube as a initial irradiation postoperatively. We hope that this treatment may affect not only ennancing palliation and better quality of life but also in local tumor control.

This is a cross-sectional study to evaluate the serum lipid levels of children living in Pusan in 1996. The distribution of age is from 2 years old to 12 years old. In female children mean total cholesterol is 171.4+/-26.2mg/dl, triglyceride is 104.7+/-50.6mg/dl, HDL-cholesterol is 54.4+/-14.8mg/dl, and LDL-cholesterol is 95.4+/-32.9mg/dl. In male children mean total cholesterol is 167.9+/-25.2mg/dl, triglyceride is 90.6+/-45.5mg/dl, HDL-cholesterol is 55.4+/-11.7mg/dll, and LDL-cholesterol is 94.4+/-23.6mg/dl. The percentile of serum lipid levels is measured in children. The 95th percentile of serum total cholesterol is 210mg/dl in male children, and 214mg/dl in female children. And, the 95th percentile of serum triglyceride is 184mg/dl in male children, and 191mg/dl in female children. And, the 95th percentile of LDL-cholesterol is 133mg/dl in male children, and 135mg/dl in female children. Serum total cholesterol is positively related to age(r=0.18), height(r=0.08), weight(r=0.17), obesity index(r=0.12), and negatively related to father's education level(r=-0.13), mother's education level(r=-0.13). Serum triglyceride is positively related to weight(r=0.23), age(r=0.31) and negatively related to father's education level(r=-0.12), mother's education level(r=-0.18). Serum HDL-C was positively related to mother's education level(r=0.07) and negatively related to height(r=-0.12), weight(r=-0.09). Conclusively, the serum lipid levels of children living in Pusan is generally so high that the family and school must try to control the serum lipid levels.

PURPOSE: The treatment strategy for elderly patients older than 80 years with diffuse large B-cell lymphoma (DLBCL) has not been established because of poor treatment tolerability and lack of data. MATERIALS AND METHODS: This multicenter retrospective study was conducted to investigate clinical characteristics, treatment patterns and outcomes of patients older than 80 years who were diagnosed with DLBCL at 19 institutions in Korea between 2005 and 2016. RESULTS: A total of 194 patients were identified (median age, 83.3 years). Of these, 114 patients had an age-adjusted International Prognostic Index (aaIPI) score of 2-3 and 48 had a Charlson index score of 4 or more. R-CHOP was given in 124 cases, R-CVP in 13 cases, other chemotherapy in 17 cases, radiation alone in nine cases, and surgery alone in two cases. Twenty-nine patients did not undergo any treatment. The median number of chemotherapy cycles was three. Only 37 patients completed the planned treatment cycles. The overall response rate from 105 evaluable patients was 90.5% (complete response, 41.9%). Twentynine patients died due to treatment-related toxicities (TRT). Thirteen patients died due to TRT after the first cycle. Median overall survival was 14.0 months. The main causes of death were disease progression (30.8%) and TRT (27.1%). In multivariate analysis, overall survival was affected by aaIPI, hypoalbuminemia, elevated creatinine, and treatment. CONCLUSION: Age itself should not be a contraindication to treatment. However, since elderly patients show higher rates of TRT due to infection, careful monitoring and dose modification of chemotherapeutic agents is needed.
