BACKGROUND: Total intravenous anesthesia (TIVA) is one of the anesthetic techniques that needs no inhalational agent but only an intravenous agent for induction and maintenance of anesthesia. Among drugs used in TIVA, propofol is the most popular agent. Rapid emergence and antiemetic characteristics of propofol are well known advantages but a dose dependent cardiovascular depressant effect is one of the disadvantages of this drug. Otherwise, ketamine, a dissociative agent, has been restricted in its use because of bad dreams, delirium and delayed emergence even though it has profound analgesic characteristics. However, ketamine has a stimulatory effect on the cardiovascular system, so it can raise blood pressure and pulse rate and in the case of TIVA, these properties can be advantageous when used with propofol. This study was aimed to decide whether TIVA using propofol and ketamine would have more stable vital signs during anesthesia and more rapid and smoother emergence in comparison with inhalational anesthesia using isoflurane. METHODS: Thirty two patients scheduled for elective general anesthesia were randomly allocated into two groups; I (inhalational anesthesia using isoflurane) group and PK (TIVA using propofol and ketamine) group. I group was controlled with isoflurane 1 - 1.5 vol% and the PK group was controlled with propofol 3 - 12 mg/kg/hr and ketamine 0.5 - 1.0 mg/kg/hr. Arriving at the recovery room, a single observer recorded the time to spontaneous movement, responses to painful pinch and verbal command, and orientation to age, name, place, date and time. At 5, 10, and 30 minutes after anesthesia, a PARS (postanesthesia recovery score), count-down test, and VAS (visual analogue scale) were checked. Postoperative events were checked in the recovery room and 24 hours lator. RESULTS: There was no significant difference in demographic data or characteristics of operation. Compared with the I group, the PK group had significantly rapid orientation responses on place, date and time. Restoration in the count-down test was more rapid in the PK group after 10 minutes in the recovery room. The VAS was lower in the PK group after 30 minutes in the recovery room. CONCLUSIONS: TIVA using propofol and ketamine has a more rapid emergence than inhalational anesthesia using isoflurane and better postoperative analgesic effect without respiratory depression.

BACKGROUND AND PURPOSE: MicroRNA (miRNA) expression has been examined in multiple conditions, including various cancers, neurological diseases, and cerebrovascular diseases, particularly stroke. Existing evidence indicates that miRNA biosynthesis and function play crucial roles in ischemic stroke physiology and pathology. In this study, we selected six known polymorphisms in miRNA-biogenesis genes; DICER rs13078A>T, rs3742330A>G; DROSHA rs10719T>C, rs6877842G>C; Ran GTPase (RAN) rs14035C>T; exportin 5 (XPO5) rs11077A>C. METHODS: We analyzed the associations between these polymorphisms and disease status and clinical factors in 585 ischemic stroke patients and 403 controls. Genotyping was performed with the polymerase chain reaction-restriction fragment length polymorphism method. RESULTS: The DICER rs3742330A>G (AA vs. AG+GG: adjusted odds ratio [AOR], 1.360; 95% confidence interval [CI], 1.024 to 1.807; P=0.034) and DROSHA rs10719T>C polymorphisms (TT vs. CC: AOR, 2.038; 95% CI, 1.113 to 3.730; P=0.021) were associated with ischemic stroke prevalence. During a mean follow-up of 4.80±2.11 years, 99 (5.91%) of the stroke patients died. In multivariate Cox proportional hazard regression models, a significant association was found between RAN rs14035 and survival of large artery disease patients with ischemic stroke (CC vs. TT: adjusted hazard ratio, 5.978; P=0.015). CONCLUSIONS: An association was identified between the DICER and DROSHA polymorphisms and ischemic stroke. Specifically, polymorphisms (rs3742330 and rs10719) were more common in stroke patients, suggesting that they may be associated with an increased risk of ischemic stroke.

PURPOSE: The aim of this study is to evaluate long-term survival and prognostic factors for radio-frequency ablation (RFA) in colorectal liver metastases. METHODS: We retrospectively reviewed 35 colorectal liver metastases patients who underwent RFA between 2004 and 2008. We analyzed survival after RFA and prognostic factors for survival. RESULTS: Of the 35 patients, 23 patients were male and 12 were female. Their mean age was 62.40 +/- 12.52 years. Mean overall survival was 38.8 +/- 4.6 months, and mean progression free survival was 19.9 +/- 3.4 months. Three- and 5-year overall survival rates were 42.7 +/- 0.1% and 26.0 +/- 0.1%, respectively. Three- and 5-year progression-free survival rates were 19.6 +/- 0.1% and 4.9 +/- 0.04%, respectively. Overall survival and progression-free survival were significantly improved in male and in patients with carcinoembryonic antigen (CEA) < or = 100 ng/mL, carbohydrate antigen (CA) 19-9 < or = 100 ng/mL, absence of extrahepatic disease, and a unilobar hepatic lesion. In addition, progression-free survival was improved in patients with a solitary hepatic lesion. On the multivariate analysis, significant survival factors were the absence of extrahepatic disease and the presence of a unilobar hepatic lesion. CONCLUSION: RFA for colorectal liver metastases is an effective treatment option in male patients and in patients with CEA or CA19-9 < or = 100, absence of extrahepatic disease, a solitary hepatic lesion, and a unilobar hepatic lesion.

PURPOSE: The purpose was to compare the marginal fidelity and the fracture resistance of the zirconia crowns according to the various coping designs with different thicknesses and cement types. Material and METHODS: Zirconia copings were designed and fabricated with various thicknesses using the CAD/CAM system (Everest, KaVo Dental GmbH, Biberach., Germany). Eighty zirconia copings were divided into 4 groups (Group I: even 0.3 mm thickness, Group II: 0.3 mm thickness on the buccal surface and the buccal half of occlusal surface and the 0.6 mm thickness on the lingual surface and the lingual half of occlusal surface, Group III: even 0.6 mm thickness, Group IV: 0.6 mm thickness on the buccal surface and the buccal half of occlusal surface and the 1.0 mm thickness on the lingual surface and the lingual half of occlusal surface) of 20. By using a putty index, zirconia crowns with the same size and contour were fabricated. Each group was divided into two subgroups by type of cement: Cavitec(R) (Kerr Co, USA) and Panavia-F(R) (Kuraray Medical Inc, Japan). After the cementation of the crowns with a static load compressor, the marginal fidelity of the zirconia crowns were measured at margins on the buccal, lingual, mesial and distal surfaces, using a microscope of microhardness tester (Matsuzawa, MXT-70, Japan, x100). The fracture resistance of each crown was measured using a universal testing machine (Z020, Zwick, Germany) at a crosshead speed of 1 mm/min. The results were analyzed statistically by the two-way ANOVA and oneway ANOVA and Duncan's multiple range test at alpha= .05. RESULTS: Group I and III showed the smallest marginal fidelity, while group II demonstrated the largest value in Cavitec(R) subgroup (P < .05). For fracture resistance, group III and IV were significantly higher than group I and II in Cavitec(R) subgroup (P < .05). The fracture resistances of Panavia-F(R) subgroup were not significantly different among the groups (P > .05). Panavia-F(R) subgroup showed significantly higher fracture resistance than Cavitec(R) subgroup in group I and II (P < .05). CONCLUSION: Within the limitation of this study, considering fracture resistance or marginal fidelity and esthetics, a functional ceramic substructure design of the coping with slim visible surface can be used for esthetic purposes, or a thick invisible surface to support the veneering ceramic can be used depending on the priority.

BACKGROUND: Laparoscopic cholecystectomy is a standard treatment for cholelithiasis and indication is continuously widened to acute and complicated cholecystitis. It has been proved to give advantages such as less postoperative pain, postoperative complications and early recovery. However, postoperative hepatic dysfunction after laparoscopic cholecystectomy has been repeatedly reported and when we evaluate postoperative hepatic dysfunction, laparoscopic surgery has been thought as one of the contributors. So authors planned this study to satisfy the growing need of reevaluation of postoperative hepatic dysfunction because we have had many achivements and improvements in knowledge and operative techniques since a while. METHODS: From January to December in 2000, 182 patients were randomly selected among who had undergone cholecystectomy in one university hospital. The numbers of each group (group OC; open, group LC; laparoscopy) were equal. Demographic data, duration of operation and level of liver enzymes (alanine transferase, alkaline phosphatase, total bilirubin and direct bilirubin) on operation day and one postoperative day were estimated by medical records. RESULTS: Mean operation time was longer in group OC than in group LC. Levels of alanine transferase, total bilirubin and direct bilirubin of postoperative one day were increased significantly in both groups. The degrees of increase of alanine transferase and bilirubin were higher in group OC than group LC in statistically significant manner. CONCLUSIONS: Laparoscopic cholecystectomy has more advantages than open cholecystectomy in many aspects.
