Purpose: Management of appendicitis in children has always been an issue in pediatric surgery. Both diagnostic methods and treatment vary significantly among medical centers, and little consensus exists in many aspects of the care for patients with appendicitis. Here, we assessed the value of drain insertion after appendectomy in children. Methods: This study is a retrospective review of pediatric patients who underwent appendectomy for perforated appendicitis at a tertiary medical center between 2003 and 2012. Patients who had a peritoneal drain inserted after appendectomy were compared with patients without drains regarding preoperative features and postoperative outcomes. Statistical analyses included a 2-tailed Student t-test and a chi-square or Fisher exact test. Results: In total, 958 patients were reviewed. Of 342 patients with perforated appendicitis, 108 (31.6%) had Jackson-Pratt (JP) drains inserted. The JP group had a longer hospital stay compared with the non-JP group (6.38 ± 3.59 days vs. 3.87 ± 2.38 days, P < 0.001). The JP group also had higher complication rates (22.2% vs. 6.8%, P = 0.003), including the formation of intra-abdominal abscesses. Conclusion: According to our results, there seems to be little evidence to support peritoneal drain insertion after appendectomy, even in perforated appendicitis cases.

The green roof system in urban area can reduce the heat island effect, which cause smog effect, human thermal discomfort, and especially increasing the energy consumption of cooling in summer. This study aims to analyze the reduction effect of heat island for green roof systems in urban area. In order to analyze the reduction effect, existing researches have been reviewed and the surface temperatures of both green roof system and typical concrete roof system have been measured in spring and summer and then compared together with local weather conditions. As the results of this study, the surface temperature differences between concrete and green roof were maximum 14.1℃ and 11.2℃ in spring and summer, respectively.

This study was designed to investigate the effect of soybean leaf extract on the development of hepatic steatosis in high fat diet-fed mice. Soybean plants were treated with ethephon to enhance the production of isoflavones in the leaves. The mice were fed with normal chow diet(ND), high fat diet(HFD) or HFD+Soybean leaf extract for 9 weeks. HFD feeding significantly increased the body weight gain and visceral and subcutaneous adipose tissue weights compared to ND group in the mice, but these increases were attenuated by Soybean leaf treatment. Soybean leaf also attenuated the increases in hepatic lipid droplet and hepatocellular triglyceride level at 64 days of HFD feeding. Finally, soybean leaf markedly increased the phosphorylation of AMPK and ACC and their protein expression in the liver at 64 days of HFD feeding, while inhibited the increase in fatty acid synthase protein expression. Our results indicate that soybean leaf extract has beneficial effects against hepatic steatosis in HFD-fed mice.

Laparoscopic surgery has become popular in the past few decades, owing to less postoperative pain, fast recovery, and better cosmetic outcomes. The laparoscopic approach has been employed in pediatric surgery for the same reasons. After the first attempts of single incision laparoscopic appendectomy in pediatrics in 1998, single incision laparoscopic surgery (SILS) has recently been proven to be safe and feasible for the pediatric population. However, limitations have been reported for SILS, such as the wide learning curve, compared to standard laparoscopic surgery, and the restricted number of hospitals with surgical training programs including SILS. In this study, we intend to present our initial experiences with SILS in children, and to describe the technique, instruments used, and outcomes. This is a retrospective study of 71 pediatric patients who underwent SILS, at a tertiary medical center, between September, 2012 and August, 2013. Electronic medical records were reviewed for demographics, type of procedure, operation time, use of additional ports, conversion to open surgery, complications and hospital stay. Additional ports were inserted in 4 cases, for the purpose of traction. Postoperative complications were noted in 13 cases, which were mostly related to wound inflammation or formation of granulation tissue. According to our analyses, patients with complications had significantly longer use and more frequent use of pain killers. Notwithstanding the small sample size, many of the procedures performed in pediatric patients seem to be possible with SILS.
