Background and Objective: Rectal washout with saline solution may theoretically prevent anastomotic recurrence in patients with resectable rectal cancer, although exact clinical effects have not yet been determined. In order to derive a more precise estimation of the relationship, the present meta-analysis was performed. Method: Relevant studies were identified by a search of Medline, Embase and Google Website with no restrictions to September 1, 2013, and included in the systematic review and meta-analysis. Results: 5 trials (642 participants) were included to assess the association between rectal washout with saline solution and anastomotic recurrence. The rate of anastomotic recurrence (AR) was 6.23% (40/642), with the pooled OR derived from the five studies being 0.32 (95 % CI=0.15-0.70, P=0.004). The pooled OR derived from the TME and radical resection subgroups were 0.72 (95%CI=0.16-3.12, P=0.66) and 0.51 (95%CI=0.13-1.96, P=0.32), respectively. Conclusion: Results from this analysis show that intra-operative rectal washout with mere saline solution largely reduces the risk of anastomotic recurrences in patients with resectable rectal cancer.

Background: Radiofrequency ablation (RFA) is the most widely used and studied method internationally for the local treatment of liver tumors. However, the extension of coagulation necrosis in one RFA procedure is limited and incomplete coverage of the damaged area can lead to a high local recurrence rate. Objective: In this study, we compared the effects of different solutions in enhancing hepatic radiofrequency by establishing a rabbit VX2 liver cancer model. We also determined the optimal solution to maximise effects on the extent of RFA-induced coagulation necrosis. Methods: Thirty VX2 tumor rabbits were randomly assigned to five groups: group A, RFA alone; group B, RFA with anhydrous ethanol injection; group C, RFA with 5% hypertonic saline injection; group D, RFA with lidocaine injection; and group E, RFA with a mixed solution. Routine ultrasound examinations and contrast-enhanced ultrasound (CEUS) of the ablation areas were performed after RFA. Then, we measured the major axis and transverse diameter and compared the areas of coagulation necrosis induced by RFA. Results: The mean ablation area range increased in groups B, C and especially E, and the scopes were greater compared with group A. Preoperative application of anhydrous ethanol, hypertonic saline, lidocaine and the mixed solution (groups B, C, D and E, respectively) resulted in larger coagulation necrosis areas than in group A (p<0.05). Among the groups, the coagulation necrosis areas in group E was largest, and the difference was statistically significant compared with other groups (p<0.05). Pathological findings were consistent with imaging results. Conclusions: A mixture of dehydrated alcohol, hypertonic saline and lidocaine injected with RFA increases the extent of coagulation necrosis in the liver with a single application, and the mixed solution is more effective than any other injection alone.

Many chemical disinfectants are using to protect the foot and mouth disease (FMD) and avian influenza (AI) in Korea since 2000. This study was performed to confirm disinfective ability of commercialized chemical disinfectants and to investigate the sterilizing ability of E-ball as alterative to chemical disinfectants. 4 kinds of acidulant, 3 kinds of aldehyde, 1 kind of oxidizer and 300 g of E-ball were used in this study. Dilution rate of disinfective power of all chemical disinfectants were to 200 times. The sterilizing ability of aldehydes were better than the acidulant and oxidizer with Salmonella typhimurium. The sterilizing ability of E-ball treated solution was guessed due to the friction of E-ball deads. In the case of the friction of 2 beads of E-ball, Salmonella typhimurium was sterilizted on $1{\times}10^6/mL$ CFU in the E-ball treated solution. The E-ball treated solution had superior sterizing power compared with the chemical disinfectants in the bacteria of soil for antibacterial examination. E-ball treated solution has a possibility as the substitute of chemical disinfectants to protective the animal diseases contains FMD, AI.

This study attempted to examine what effect knowledge management factors have on cooperative organizational culture regarding knowledge sharing depending on workplace types and occupations in order to seek for solution to increase efficiency and effects of knowledge management in the hospital organization. Key findings are as follows: For members of the hospital organization, the higher their recognition was in relation to 'concern and support of chief executive officer for knowledge management', and 'problem solution by specialists or superior in the organization and acquisition on the task knowledge', the more they worked as factors exerting positive effects on 'cooperative organizational culture regarding knowledge sharing'. And influence factors were different depending on workplace types and occupation.

Purpose: Glucose has been recommended as an analgesic for mild to moderately painful procedures in neonates. The goal of this study was to assess the optimal dextrose concentration for pain control in newborns. Methods: This prospective, randomized, blinded clinical trial included 116 healthy full-term newborns. The neonates were randomly assigned to the following four groups by drawing straws: groups receiving sterile water or a 10%, 20%, or 40% dextrose solution orally. Each group was treated with the assigned solution prior to hepatitis B vaccination. The Neonatal Facial Coding System (NFCS) and the Neonatal Infant Pain Scale (NIPS) scores were evaluated before, immediately after, and 2 minutes after the injection in all neonates. Premature Infant Pain Profile (PIPP) scores were evaluated during the injection. All procedures were video-recorded, and pain scores were assessed by two independent observers who were not involved in the care of the newborns studied. The pain scores were compared among the four groups. Results: The 40% dextrose solution significantly reduced the NFCS (P=0.002) and the PIPP scores (P=0.001) compared with sterile water. No hyperglycemic events were noted in the study subjects 2 hours after the injection. Conclusion: The 40% dextrose solution effectively relieved pain due to intramuscular injection in full-term newborns without causing hyperglycemic events. However, the 10% and 20% dextrose solutions did not affect neonatal pain scores.

Purpose:Plaster splints are routinely performed in the Emergency Department (ED) and avoidable complications such as skin ulcerations and fracture instability arise mainly due to improper techniques. Despite its frequent use, there is often no formal training on the fundamental principles of plaster splint application for a medical officer rotating through ED. We aim to use Quality Improvement (QI) methodology to reduce number of incorrect plaster splint application to improve overall patient care via a bundled educational solution. Methods: We initiated a QI program implementing concepts derived from the Institute for Healthcare Improvement models, including Plan-Do-Study-Act (PDSA) cycles, to decrease the rate of incorrect plaster splint application. A bundled education solution consisting of three sequential interventions (practical teaching session, online video lecture and quick reference cards) were formulated to specifically target critical factors that had been identified as the cause of incorrect plaster splints in ED. Results: With the QI intervention, our overall rate of incorrect plaster splints was reduced from 84.1% to 68.6% over a 6-month period. Conclusion: Following the QI project implementation of the bundled educational solution, there has been a sustained reduction in incorrect plaster splints application. The continuation of the training program also ensures the sustainability of our efforts in ED.

The purpose of this study is to evaluate whether water soluble chitosan, a natural nontoxic chelator, can reduce fetal contamination of radiostrontium in pregnant mice. Various forms of water soluble chitosans (10% or 1% powder, or 1% solution) were given to pregnant mice before or after contamination of 0.005 uCi/B.W(g) Sr-85. Transplacental transfer of Sr-85 to fetus was $6.8{\pm}2.7%$ of injected dose, when Sr-85 was administered at the 20th day of pregnancy. Fetal radioactivity was significantly reduced when mother mice were treated with water soluble chitosan before contamination of Sr-85. Water soluble chitosans of 10% or 1% powder, or 1% solution significantly reduced fetal retention of Sr-85 to $2.3{\pm}0.7%$, $2.7{\pm}0.8%$, and $2.0{\pm}0.9%$, respectively. However, fetal contamination was not reduced, when water soluble chitosans of 10% or 1% powder, or 1% solution were administered after maternal contamination of Sr-85. From these data we can conclude that water soluble chitosan could reduce fetal contamination of radiostrontium in pregnant mice, when given before the pregnant mice were exposed to radiostrontium.

Oral rehydration solution (ORS) is safe and effective for the prevention and treatment of dehydration in children. It has been commercially available as a small packaging unit that needs to be taken with a specified amount of water. Intake of incorrectly formulated ORS results in side effects, such as electrolyte imbalance and upper gastrointestinal (GI) disturbance. We experienced a case of severe GI hemorrhage from gastric and duodenal ulcers in a previously healthy child following intake of incorrectly formulated ORS. GI hemorrhage in children is often life threatening and reaching a diagnosis may be challenging. Commercially manufactured packets of powdered oral rehydration salts have been widely used and GI hemorrhage associated with an improperly diluted ORS has been rarely reported. Caution and education for proper preparation of ORS are imperative.

Purpose: The aim of this study was to identify the effect of Dongchimi juice containing kimchi Lactobacillus as an oral hygiene agent and to compare it with that of chlorhexidine solution (0.12% dilution). Methods: This study employed a pretest-posttest experimental design in which a single group of patients was exposed to two different treatments over a period of time. The study included 32 patients hospitalized at a longterm care hospital in Korea. Data were collected between August 12, 2016 and September 28, 2016. The patients first used chlorhexidine solution as an oral care agent for 1 week. After an interval of 2 weeks, they used Dongchimi juice for 1 week. Each agent was applied 2 times a day depending on the protocol. The oral status of the patients was measured using Beck's Oral Exam Guide (OEG) scores. The number of pathogens in the oral cavity was counted by culture, and the patients' subjective satisfaction score for each oral agent was measured using a visual analogue scale. T-test and Mann-Whitney test were performed to identify significant differences between Dongchimi juice and chlorhexidine solution by using PASW Statistics for Windows, Version 18.0 (SPSS Inc., Chicago, IL, USA). Results: The OEG score was not statistically different with the use of chlorhexidine solution and Dongchimi juice. However, decreasing number of pathogens and the subjective satisfaction score were higher with Dongchimi juice than with the chlorhexidine solution. Conclusion: These findings support the use of Dongchimi juice containing kimchi Lactobacillus as an oral hygiene agent for Korean patients.
